Description

Technical Field

[0001] The invention relates to a single-pendulum swing and a single-pendulum rotating wheel, belonging to amusement facilities. Background Art

[0002] When you see people swinging on the swings in the park, there is no external force pushing or pulling. It all depends on the person swinging to stand up and push off repeatedly. By repeating this action, the swing will swing higher and higher, and some can even do a 360-degree rotation.

[0003] At present, all the amusement facilities in amusement parks that perform rotating or reciprocating swinging motion, such as pirate ships, pendulums, Ferris wheels, etc., are mostly driven by electric motors after the speed is changed by a reduction gearbox, and then driven by transmission parts such as pulleys or rubber friction wheels. This common transmission method has a complex structure, low transmission efficiency, large motor power, and a single motion trajectory.

[0004] In the existing double pendulum device, the movement trajectory of the heavy ball is in a chaotic pendulum state with no regularity and cannot be used. Summary of the invention

[0005] The present invention aims to provide a single pendulum swing and a single pendulum rotating wheel. The single pendulum swing can reduce the cost, save driving power, and reduce operating costs. Furthermore, the single pendulum rotating wheel can increase the motion track, so that tourists can enjoy the feeling of a variety of amusement facilities.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A single-pendulum swing comprises a swing rod and a seat connected to the outer end of the swing rod, and its structural feature is that the swing rod is connected to a telescopic electromagnet that can swing around a rotating shaft;

[0008] The seat has one of the following two states during the swinging process:

[0009] State 1: When the seat moves from the front dead point or the rear dead point to the lowest point, the iron core of the telescopic electromagnet extends so that the seat has the maximum swing radius;

[0010] State 2: When the seat moves from the lowest point to the front dead point or the rear dead point, the iron core of the telescopic electromagnet retracts so that the seat has the minimum swing radius.

[0011] Based on the swinging movement phenomenon, the inventor summarized a law of simple pendulum movement: if the length of the swing arm of a moving simple pendulum can change continuously, and the frequency of change is synchronized with the frequency of the swinging ball and resonates, that is, the swing arm shortens when swinging up and lengthens when swinging down, the energy is superimposed, and the simple pendulum will swing continuously, and the swing amplitude will become larger and larger, and it can even rotate 360 ​​degrees. Using this law, the inventor designed a series of swinging or rotating amusement devices with adjustable pendulum rod length.

[0012] The present invention adopts the law of simple pendulum motion and utilizes telescopic electromagnet drive to repeatedly change the length of the swing arm, so that a gravity difference is generated on the left and right sides of the center line of the amusement device, thereby driving the device to continuously perform reciprocating swing or circular rotation motion. This simplifies the structure, reduces the cost, saves driving power, reduces operating costs, and at the same time increases the motion trajectory, allowing tourists to enjoy the feeling of a variety of amusement facilities.

[0013] According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

[0014] In one of the preferred embodiments, the lower end of the iron core is fixedly connected to the rocker arm via a threaded joint.

[0015] In one of the preferred embodiments, the iron core retracts when the telescopic electromagnet is energized, and extends when the power is off.

[0016] Based on the same inventive concept, the present invention also provides a single pendulum wheel, which comprises a polygonal frame formed by connecting a plurality of guide rails end to end, each guide rail being supported on a central axis through a corresponding wheel hub;

[0017] Each guide rail includes a straight guide rail section and arcuate guide rail sections located at both ends of the straight guide rail section, and baffles are provided at the outer ends of the arcuate guide rail sections;

[0018] A pulley is provided in the guide rail, and two roller shafts are installed on the pulley support plate of the pulley, and pulley rollers are installed on the roller shafts accordingly; a swing rod support shaft extending relative to the side wall of the guide rail is provided in the middle of the pulley support plate, and the single pendulum swing is installed on the swing rod support shaft through a one-way bearing;

[0019] The pulley roller in each guide rail reciprocates between two arc-shaped guide rail sections, and the two arc-shaped guide rail sections face opposite directions.

[0020] In one of the preferred embodiments, a buffer rubber plate or a force storage spring is provided on the inner side of the baffle.

[0021] In one preferred embodiment, the center hole of the baffle is slidably connected to a helical gear slide rod extending from the end of the guide rail, and the force storage spring sleeved on the helical gear slide rod is located between the roller baffle and the end of the guide rail; the helical gear slide rod is provided with an oblique groove;

[0022] A torsion spring is installed on the outer side of the end of the guide rail, and the torsion end of the torsion spring is connected to a lever, which is inserted into the oblique groove of the oblique gear slide rod through an oblique surface pin. When the force storage spring is compressed and the oblique gear slide rod extends outward, the oblique surface pin disengages from the oblique groove.

[0023] In one preferred embodiment, there are six guide rails, which are connected end to end to form a hexagonal frame.

[0024] Based on the same inventive concept, the present invention also provides a hybrid single pendulum swing, which includes a main shaft support seat fixed above a frame, a long pendulum main shaft mounted on the main shaft support seat, a long pendulum square sliding sleeve, a lifting and swinging device, a first force storage device located on the left side of the long pendulum main shaft, a second force storage device located below the long pendulum main shaft, and a third force storage device located on the right side of the long pendulum main shaft;

[0025] The lifting and swinging device comprises a long swing rod A, a short swing rod B and a passenger cabin; one end of the long swing rod A is connected to the main shaft of the square sliding sleeve, the other end of the long swing rod A is hingedly connected to one end of the short swing rod B through a short swing support shaft, and the other end of the short swing rod B is connected to the passenger cabin;

[0026] The first force storage device and the third force storage device are symmetrically arranged relative to the long pendulum main axis and have the same structure;

[0027] The cabin has one of the following two states during the swinging process:

[0028] State 1: when the lifting and swinging device moves from being separated from the first force storage device or the third force storage device to being in contact with the second force storage device and swinging downward, the swing radius of the swinging device is the length L1 of the long swing rod A plus the length L2 of the short swing rod B (referred to as the extended swing rod);

[0029] State 2: When the lifting and swinging device moves from being separated from the second force storage device to being in contact with the first force storage device or the third force storage device and swings upward, the swing radius of the swinging device is (Shortened pendulum C for short).

[0030] In one of the preferred embodiments, the first force storage device and the third force storage device both include a movable inclined pressure plate mounted on a pressure plate fixed rotating shaft, a telescopic electromagnet arranged at the lower side of the movable inclined pressure plate for driving the movable inclined pressure plate to swing, and a pressure plate spring arranged at the upper side of the movable inclined pressure plate for storing energy; when the passenger cabin swings to below the movable inclined pressure plate, the movable inclined pressure plate is driven to swing upward around the pressure plate fixed rotating shaft, thereby compressing the pressure plate spring.

[0031] In one of the preferred embodiments, the second force storage device includes a collision arc seat located directly below the long pendulum main axis and a large force storage spring arranged on the side of the collision arc seat away from the long pendulum main axis; when the cabin swings to the lowest point, the collision roller drives the collision arc seat to compress the large force storage spring to the shortest length.

[0032] In one preferred embodiment, when the large force storage spring is in a free state, the length L1 of the long pendulum rod A is greater than the distance between the highest convex surface of the collision arc seat and the rotation center of the long pendulum main shaft;

[0033] When the large force storage spring is in the maximum compression state, the distance between the highest convex surface of the collision arc seat and the rotation center of the long pendulum main shaft is equal to the length L1 of the long pendulum rod A;

[0034] During the rolling of the collision roller along the collision arc seat, the cabin is located in front of the long swing rod A. This is because the collision roller installed on the long swing rod A is subject to resistance, while the short swing rod B is not subject to resistance, so the cabin swings at the original swing speed, while the swing speed of the long swing rod A lags behind.

[0035] In one of the preferred embodiments, inclined guide rails are symmetrically arranged on both sides of the collision arc seat, and when the collision roller moves along the inclined guide rails, the long rocker arm A and the short rocker arm B are located on the same straight line, and the swing radius of the swing device is equal to the length L1 of the long rocker arm A plus the length L2 of the short rocker arm B.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The safety seat of the present invention accurately controls the swing amplitude by adjusting the power-on time and current of the telescopic electromagnet. The on and off of the coil power supply can be automatically controlled or manually controlled by the tourist, so that tourists can flexibly adjust the swing amplitude of the safety seat according to their own physical condition, and it also helps to improve the tourists' reaction ability.

[0038] 2. Through the present invention, tourists can experience the excitement brought by a variety of motion trajectories, and the amount of exercise will also increase accordingly. It is worth mentioning that the entire device does not need to be driven by a high-power motor, and can be driven to operate only by powering on the low-power telescopic electromagnets in sequence. The power-on time of the low-power telescopic electromagnet only needs to meet the time required for a specific turning angle, which greatly saves electricity and effectively reduces operating costs. In addition, this embodiment eliminates the need for rubber friction wheels, reduction boxes, high-power motors, and friction rollers with a diameter of tens of meters, which not only simplifies the structure and reduces the cost, but also enriches the motion trajectory, allowing tourists to experience a variety of amusement facilities and achieve low-cost, high-quality operations.

[0039] 3. The present invention cleverly uses the elastic potential energy stored in the power storage spring to increase the initial velocity of the four-wheel pulley before sliding down, thereby increasing the sliding speed. At the same time, the travel of the telescopic electromagnet is shortened, and the power consumption is also reduced. In addition, this embodiment also uses the impact force of the heavy ball on the roller baffle when it is at the lowest position and the pulling force (i.e., centrifugal force) generated on the swing rod to do work, further saving electricity and reducing operating costs.

[0040] 4. The present invention combines the single pendulum device and the double pendulum device in an orderly manner. When the heavy ball swings downward, the swing arm extends; when it swings upward, the swing arm shortens. This design increases the torque of gravity doing work during the downward swing and reduces the torque of gravity doing negative work during the upward swing, thereby saving driving power.

[0041] 5. The present invention cleverly designs the structure of the long pendulum square sleeve and the square slider. When the pendulum ball swings to the lowest position and the centrifugal force is the largest, the long pendulum square sleeve moves upward a short distance under the action of the collision roller and related parts. At this time, all impact forces and centrifugal forces no longer act on the long pendulum main shaft, but are all pressed on the large force storage spring and converted into elastic potential energy for storage. When the pendulum rod just swings past the vertical position, the long pendulum square sleeve immediately drops and hangs on the square slider. At this time, the weight of the entire swing device is supported by the long pendulum main shaft, and the elastic potential energy stored in the large force storage spring is fully released and converted into kinetic energy, pushing the heavy ball to quickly swing up around the long pendulum main shaft, increasing the upward swing amplitude.

[0042] 6. The present invention ingeniously adopts the timed conversion of single and double pendulums. When the pendulum ball swings down from a high place, the device is a single pendulum structure with a long swing arm, a high swing speed and a large impact force. Before the pendulum ball collides with the spring seat, the device quickly transforms into a double pendulum structure through the inclined guide rail. After the collision, the pendulum ball can still continue to swing at the original speed, and the swing speed is not affected. At this time, the impact force and centrifugal force compress the large spring, and the stored pressure potential energy is released during the upward swing movement, becoming the power to push the heavy ball to swing up quickly.

DETAILED DESCRIPTION

[0058] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0059] Example 1: Telescopic electromagnet single pendulum swing

[0060] See also Figure 1 In the telescopic electromagnet single pendulum swing of this embodiment, a rotating shaft 3 is symmetrically fixedly arranged in the middle of the telescopic electromagnet 1. The two ends of the rotating shaft 3 are connected to the bearing seat (not shown in the figure) through bearings 2. The lower end of the iron core 5 is fixedly connected to the swing rod 7 through a threaded joint 6, and the other end of the swing rod 7 is fixedly connected to the safety seat 8. Figure 2In the figure, the safety seat 8 has been swung to the high position on the right. At this time, the iron core 5 of the telescopic electromagnet 1 has been completely sucked in, and the length of the swing rod 7 is the shortest. Under the action of gravity, when the safety seat 8 is ready to swing down in the clockwise direction, the coil 4 is de-energized. Figure 3 , under the action of gravity, the iron core 5 extends downward, and the swing rod 7 is at its longest size. Figure 3 Swing down clockwise to the high position on the right (see Figure 4 ) is in a vertical position, at which time the swing rod 7 is at its longest dimension, and the torque of the safety seat 8 doing positive work when it swings down is large. Figure 5 At this time, the telescopic electromagnet coil 4 is energized and the iron core 5 is sucked in. At this time, the swing rod 7 is at its shortest size. Under the action of inertia, the safety seat 8 swings clockwise from the lowest vertical position to Figure 6 Left high position shown, see Figure 6 , at this time, the swing rod is the shortest, and the torque of the upward swing is small. When the safety seat 8 is ready to swing down counterclockwise, the telescopic electromagnet coil 4 is powered off. Figure 7 Under the action of gravity, the iron core 5 has been fully extended, and the swing rod 7 is now at its longest dimension, i.e., at its maximum swing radius. At this time, the safety seat 8 begins to swing downward in the counterclockwise direction, and the torque of the downward swing doing positive work increases. Repeat this process. Figure 1 The working sequence of the present invention is that the single pendulum swing of the present invention just keeps swinging.

[0061] The swing amplitude of the safety seat 8 in this embodiment can be controlled by adjusting the power-on time and current of the telescopic electromagnet 1. The on and off of the power supply of the coil 4 can be automatically controlled, or the tourist can manually control the remote control switch. The tourist can adjust the swing amplitude of the safety seat according to his or her own physical condition, and the tourist's reaction ability is also improved.

[0062] In this embodiment, it can be seen that the direction in which the telescopic electromagnet pulls the pendulum rod upward is always perpendicular to the direction in which the heavy ball swings. Since the upward pulling force of the pendulum rod on the heavy ball can do work, the downward pulling force (centrifugal force) of the heavy ball on the pendulum rod can also do work. Based on this inference, the inventor designed the technical solutions of Embodiments 2-4.

[0063] Example 2: Single pendulum wheel with multiple motion tracks

[0064] This embodiment takes a hexagonal wheel as an example, see Figure 8 , 9 , 10, 11 to introduce the structure and working principle of the "multi-motion track single pendulum wheel". Figure 8As shown, six guide rails 221, 222, 223, 224, 225, 226 are arranged in a hexagonal shape, and each guide rail has a small arc track with a rotation angle of 60 degrees at both ends, and the ends are connected. The hexagonal guide rail is evenly supported by six wheel hubs and rotates around the central axis.

[0065] Each guide rail is equipped with a Fig.17 The four-wheeled pulley 442 shown, see Fig. 9 , the pulley roller 204 slides on the inner wall 202 of the guide rail. Figure 8 and Fig. 9 A short section of circular arc guide rail with a 60-degree angle is fixedly connected to the two ends of the linear guide rail. A baffle 203 is fixedly arranged at the outer end of the circular arc guide rail, and a buffer rubber plate 211 is arranged on the inner side of the baffle 203 for buffering. Fig.10 , the figure is attached Fig. 9 B-direction sectional view. Four roller shafts 205 are fixedly arranged at both ends of the pulley support plate 206. Four pulley rollers 204 are correspondingly mounted on the four roller shafts 205. In the middle of the pulley support plate 206, a swing rod support shaft 207 is extended from a side. The swing rod 7 is fixedly connected to the swing rod bearing sleeve 209, and its inner hole is connected to the swing rod support shaft 207 through a one-way bearing 208. The swing rod 7 can rotate in one direction around the swing rod support shaft 207. Fig.11 for Fig. 9 AA rotated section view, from Fig.11 As can be seen from the figure, the outer diameter of the pulley roller 204 is smaller than the inner space of the guide rail inner wall 202, and the pulley roller 204 can only slide on any side of the guide rail inner wall 202. Fig.10 and Fig.11 It can also be seen that the rocker arm support shaft 207 extends out from the guide rail side groove 201, and a one-way bearing 208 and a rocker arm assembly are installed on its journal.

[0066] The working principle is introduced below: Figure 8 The first guide rail 221 and the fourth guide rail 224, the four-wheel pulley 442 are all stopped at the upper ends of the first guide rail 221 and the fourth guide rail 224, which are inclined at 30 degrees. The baseline of the four-wheel pulley 442 (i.e., the pulley support plate 206) is parallel to the guide rails, i.e., it is also inclined at 30 degrees. Under the action of the gravity of the heavy ball, the pendulum 7 is in a vertical state. That is, the included angle with the baseline of the four-wheel pulley 442 is 60 degrees. A telescopic electromagnet 1 is set on the upper half of each pendulum 7. At this time, the iron core 5 is pushed out, so the pendulum 7 has the longest dimension. See the attached Fig.12The first guide rail 221 and the fourth guide rail 224 in the embodiment, the four-wheel pulley 442 slides from the upper end of the first guide rail 221 and the fourth guide rail 224 of the 30-degree slope to the lower end. At this time, the baseline of the four-wheel pulley 442 is parallel to the guide rail, that is, it is also inclined at 30 degrees. At this time, the swing rod 7 is still in a vertical state, and the length of the swing rod 7 is still the longest dimension. Fig.13 The first guide rail 221 and the fourth guide rail 224 in the four-wheel pulley 442 slide down to the end of the 60-degree angle circular arc guide rail, and return to the middle of the short circular arc guide rail after colliding with the rubber baffle 211. At this time, the baseline of the four-wheel pulley 442 is in a horizontal state. At this time, the swing rod 7 cannot swing down in the clockwise direction under the action of the one-way bearing 208, and still maintains a state of 60 degrees with the baseline of the four-wheel pulley 442. At this time, the telescopic electromagnet 1 is positively energized through the carbon brush conductive ring, and its iron core 5 is sucked in. The swing rod 7 is in the shortest state. Under the action of inertia, the heavy ball swings up counterclockwise around the center of the swing rod support shaft 207. See Fig.14 When the heavy ball is swinging counterclockwise upward, the swing rod 7 has the shortest dimension, so the swing amplitude is increased a lot. At this time, the swing rod 7 swings counterclockwise to the outside of the first guide rail 221 and the fourth guide rail 224 with a slope of 30 degrees. Fig.15 After the weight ball ends its upward swinging motion, the telescopic electromagnet 1 is reversely energized through the carbon brush conductive ring and its iron core 5 is pushed out. At this time, the swing rod 7 is at its longest dimension. Since the one-way bearing 208 controls the swing rod 7 to swing counterclockwise, it cannot swing clockwise. Fig.15 The six pendulums in the system all maintain the angle between the corresponding guide rails and the uppermost position, and cannot make a clockwise downward swing motion, thus increasing the torque for doing positive work. At this time, the three weight balls corresponding to the three guide rails 221, 222, and 223 on the right side of the vertical center line of the hexagonal guide rail are far away from the vertical center line, while the three weight balls corresponding to the three guide rails 224, 225, and 226 on the left side of the center line are close to the vertical center line, that is, the downward torque on the right side of the center line is greater than the downward torque on the left side of the center line, and at this time the hexagonal guide rail rotates clockwise around the central axis. See Fig.16 At this time, the hexagonal guide rail rotates 30 degrees clockwise around the center of the circle. Fig.15The sixth guide rail 226, which was tilted at an angle of 30 degrees in the upper left center, has now been rotated to a horizontal position directly above. At this time, the angles between the upper and lower horizontal sixth guide rails 226 and the third guide rail 223 and the corresponding swing rods cannot be greater than 90 degrees due to the effect of the one-way bearing 208, while the angles between the swing rods corresponding to the other four guide rails all maintain the angles when the swing rods are swung to the highest position. At this time, there are 4 heavy balls on the left side of the vertical center line, but they are very close to the vertical center line. There are only two heavy balls on the right side of the vertical center line, but they are very far away from the vertical center line. At this time, the downward torque on the right side of the center line is still greater than the downward torque on the left side of the center line. The hexagonal guide rail continues to rotate 30 degrees clockwise and returns to the clockwise direction. Figure 8 See Figure 8 The first guide rail 221 and the fourth guide rail 224, and their corresponding two pendulum rods 7 are both in a vertical state, and the angle between them and the guide rails is 60 degrees, instead of 90 degrees as shown by the dotted positions 231 and 232 of the heavy ball in the figure. This is because the one-way bearing allows the pendulum rod 7 to rotate counterclockwise, and under the action of gravity, the pendulum rod 7 swings counterclockwise to a vertical position, which increases the torque for doing positive work. At this time, the pendulum rod 7 is at its longest dimension, and under the action of gravity, it begins to slide down along the 30-degree inclined guide rail, repeating the previous working cycle. In this way, the hexagonal guide rail operates over and over again. In order to simplify the drawing, Figure 8 , Figure 12-16 A heavy ball was used instead of a safety seat.

[0067] Through this embodiment, tourists can enjoy the stimulation of multiple motion trajectories and increase the amount of exercise. The total platform machine in this embodiment does not need a high-power motor to drive, but only needs to be powered on sequentially by low-power telescopic electromagnets. In addition, the power-on time of the low-power telescopic electromagnet is only 90 degrees of rotation time, which greatly saves electric energy and reduces operating costs. This embodiment saves rubber friction wheels, reduction boxes, high-power motors, and friction rollers with a diameter of tens of meters, simplifies the structure, reduces the cost, increases the motion trajectory, and enables tourists to enjoy a variety of amusement facilities. At the same time, it also reduces operating costs and is inexpensive and good quality.

[0068] Example 3: Spring-powered pendulum wheel

[0069] from Figure 8 , 9As can be seen from Figures 1 and 12, when the four-wheel pulley 442 slides from the upper dead point of the 30-degree inclined first guide rail 221 to the lower dead point, the pulley roller 204 collides with the buffer rubber baffle 211 for buffering, and then the four-wheel pulley 442 stops. At this time, the swing rod 7 continues to swing counterclockwise around the one-way bearing 208 under the inertia force of the heavy ball. The impact force at this time and the pulling force (centrifugal force) on the swing rod 7 when the heavy ball swings counterclockwise are all absorbed by the buffer rubber baffle 211, and cannot do work to the outside. In this embodiment, the buffer rubber baffle 211 is changed to Fig.18 The spring force storage device shown can convert the impact force and the pulling force (centrifugal force) of the heavy ball on the swing rod 7 into power to increase the initial speed of the four-wheel pulley 442 when it slides down in the next working cycle.

[0070] Fig.18 It is a partial enlarged view of the spring force storage component. When the four-wheel pulley 442 is at the position of the upper dead point of the first guide rail 221 at an angle of 30 degrees, the gravity of the heavy ball causes the four-wheel pulley 442 to start sliding down through the action of the swing rod 7 and the one-way bearing 208 and other components. The initial velocity at this time is 0. At this time, the pulley support plate 206 is parallel to the first guide rail 221, and both are inclined at an angle of 30 degrees to the horizontal line. The swing rod 7 is in a vertical state under the gravity of the heavy ball, and the angles with the first guide rail 221 and the pulley support plate 206 are both 60 degrees. The four-wheel pulley 442 slides down from the upper dead point of the first guide rail 221. When it is about to reach the lower dead point, the pulley roller 204 collides with the roller baffle 219, and the force storage spring 220 begins to be compressed. When the four-wheel pulley 442 slides to the middle of the short arc guide rail, the force storage spring 220 has been compressed to a certain extent, and the helical gear slide bar 213 extends a certain length to the right outer end. Under the action of the torsion spring 214, the lever 215 presses the inclined surface pin 216 downward in the clockwise direction 228 and locks the helical tooth slide bar 213. At this time, the force storage spring 220 converts the impact kinetic energy of this (first) cycle into elastic potential energy and stores it. At this time, the pulley support plate 206 is in a horizontal state, and the swing rod 7 cannot swing in the clockwise direction under the action of the one-way bearing 208, and still maintains an angle of 60 degrees with the pulley support plate 206. In other words, at this time, the swing rod 7 swings 30 degrees counterclockwise from the vertical state.

[0071] Since the initial velocity of the four-wheel pulley 442 is 0 when it slides down from the top dead point of the 30-degree inclined first guide rail 221 in this cycle (the first cycle), its final velocity can be calculated as a free fall, and its descending height is a 30-degree sine, which is exactly equal to half the length of the inclined first guide rail 221. Assuming that the length of the first guide rail 221 is 4 meters, its descending height is 2 meters at this time. If the friction resistance is negligible, the final velocity when sliding down is 6.26m / s. At this time, the impact force of 6 times the mass of the heavy ball acts on the power storage spring 220 and compresses it to a certain size. When the four-wheel pulley 442 is stopped by the roller baffle 219, the swing rod 7 is still in the direction of movement under the action of the inertia force of the heavy ball, and continues to swing counterclockwise at the original speed around the center of the one-way bearing 208 with the swing rod 7 as the radius. At this time, the centrifugal force generated acts on the power storage spring 220 through the one-way bearing 208, the swing rod support shaft 207 and other components, further compressing it. At this time, the helical gear slide 213 extends a certain length to the right outer end again, and the lever 215 presses the inclined surface pin 216 downward in the clockwise direction 228 under the action of the torsion spring 214, and the helical gear slide 213 is stuck and cannot rebound. In this (first) cycle, the kinetic energy of the four-wheel pulley 442 acting on the power storage spring 220 is all stored as elastic potential energy.

[0072] Wait until the next working cycle, see Fig.19 As shown, after the first guide rail 221 with an inclination of 30 degrees rotates 180 degrees clockwise and turns to the position of the fourth guide rail 224 with an inclination angle of 30 degrees, near its upper dead center, the inclined surface bump block 233 of the lever 215 fixed there presses the ball head 229 of the lever 215 in the counterclockwise direction. At this time, the inclined surface latch 216 is pulled up, and the elastic potential energy of the force storage spring 220 is converted into kinetic energy, pushing the roller baffle 219 forward and pushing the four-wheel pulley 442 to slide down quickly along the fourth guide rail 224 with an inclination of 30 degrees. In this (second) cycle, the initial speed of the four-wheel pulley 442 will be greatly improved. Fig.10 , Fig.18 Due to the one-way bearing 208, the pendulum 7 cannot swing clockwise. At this time, the support shaft 207 drives the pendulum 7 and the heavy ball to slide down synchronously and quickly through the one-way bearing 208 and the pendulum bearing sleeve 209. Fig.18 and Fig.19, when the four-wheel pulley 442 quickly slides to the lower dead point of the fourth guide rail 224, the pulley roller 204 collides with the roller baffle 219, and the force storage spring 220 is compressed again. Since the initial velocity of this (second) cycle has increased, its final velocity has also increased accordingly, and its collision force has also increased a lot. At this time, the centrifugal force of the heavy ball and the swing rod 7 doing counterclockwise upward swinging motion has also increased a lot, and the height of the heavy ball swinging upward has also increased accordingly. At the same time, the pressure acting on the force storage spring 220 has also increased a lot, that is, in this (second) cycle, the elastic potential energy stored by the force storage spring 220 is greater than that in the last (first) cycle. Wait until the next (third) cycle to release the stored elastic potential energy, and push the four-wheel pulley 442 to slide down quickly to obtain a larger initial speed.

[0073] The upper end of the swing rod 7 of this embodiment is also provided with a telescopic iron 1 (not shown in the figure). When the swing rod 7 is swinging upward, its length is shortened to reduce its upward swing resistance. When the swing rod 7 is swinging downward, the swing rod is extended to increase the torque of its downward swing to do positive work. Fig.19 , the four-wheel pulley 442 is ready to slide down at the top dead center of the first guide rail 221, at which time the swing rod 7 is at its longest size and the heavy ball is at the position 18-a. When the four-wheel pulley 442 slides to the bottom dead center of the first guide rail 221, before the swing rod 7 is ready to swing upward, that is, before the four-wheel pulley 442 collides with the roller baffle 219, the telescopic electromagnet 1 is energized in the forward direction through the carbon brush collector ring, and its iron core 5 is sucked in, causing the length of the swing rod 7 to shorten, and the heavy ball is shortened from the position 18-a to the position 17-B, thus reducing the resistance of the heavy ball when it swings upward. When the heavy ball swings upward to the position 17-B1, the telescopic electromagnet is energized in the reverse direction, and its iron core extends, causing the swing rod 7 to lengthen, and the heavy ball is translated to the position 18-a1, thus increasing the torque of the downward swing.

[0074] See also Fig.19At the point on the first guide rail 221 inclined at 30 degrees, the swing rod 7 is in a vertical state under the gravity of the heavy ball. When the heavy ball swings from the position 18-a to the position 18-a1, the swing rod 7 is in a horizontal state, and the angle between the swing rod 7 and the first guide rail 221 inclined at 30 degrees is 150 degrees. Due to the effect of the one-way bearing 208, the swing rod 7 cannot swing downward in the clockwise direction and can only remain in the original state. When the first guide rail 221 rotates clockwise to the position of the second guide rail 222, the heavy ball rotates from the position 18-a1 to the position 18-a2, and the angle between the swing rod 7 and the guide rail is still 150 degrees. When the first guide rail 221 rotates to the position of the third guide rail 223, if the angle between the swing rod 7 and the guide rail is still 150 degrees, the heavy ball needs to rotate from the position 18-a1 to the position 18-a3. When the first guide rail is rotated clockwise to the position of the fourth guide rail 224, if the swing rod 7 and the guide rail still maintain an angle of 150 degrees, the heavy ball will rotate from the position 18-a1 to the position 18-a4. If this is the case, the torque of doing negative work will be greatly increased. Due to the effect of the one-way bearing 208, the swing rod 7 will not swing past the vertical position of the corresponding point, which can greatly reduce the torque of doing negative work.

[0075] This embodiment utilizes the elastic potential energy stored in the force storage spring 220 to increase the initial velocity of the four-wheel pulley 442 before sliding down, and its final velocity is also increased accordingly, the stroke of the telescopic electromagnet 1 used is also shortened accordingly, and its power consumption is also reduced accordingly. This embodiment utilizes the impact force of the heavy ball on the roller baffle 219 and the pulling force (i.e., centrifugal force) generated on the swing rod 7 when the heavy ball is at the lowest position to do work, which plays a role in saving electric energy and reducing operating costs.

[0076] Embodiment 4: A "hybrid single pendulum swing" with an orderly spring force storage motion trajectory.

[0077] In the existing double pendulum device, the motion trajectory of the heavy ball is a chaotic pendulum with no rules. This embodiment controls it to become a hybrid single pendulum device with an orderly motion trajectory. Under the action of the storage spring and other components, the structure of the device is regularly converted between a single pendulum and a double pendulum during the swinging process, so that the swing arm of the hybrid single pendulum swing is shortened when doing the upward swing movement, and the swing arm is extended when doing the downward swing movement, so as to achieve the purpose of saving energy consumption by the continuous swinging of the device.

[0078] See also Figure 20-21The main shaft support seat 45 fixed on the frame is connected to the two shaft heads of the long pendulum main shaft 44 and fixed by the set screw 43. The square slider 42 is rollingly connected to the long pendulum main shaft 44 through two main shaft bearings 46. The inner guide rail of the long pendulum square sliding sleeve 41 is rollingly connected to the outer guide rail of the square slider 42 through the sliding ball 430, so that it can slide freely up and down. The lower end of the long pendulum square sliding sleeve 41 is fixedly connected to two symmetrical long pendulum rods A47, and its length is L1. The short pendulum support hole 429 is correspondingly opened at the lower end of the long pendulum rod A47, and two support shaft bolts 420 pass through the short pendulum support hole 429 and fix the short pendulum support shaft 422 on the two symmetrical long pendulum rods A47. The short pendulum positioning bearing sleeve 419 is connected with the short pendulum support shaft 422 by two short pendulum bearings 421 in a rolling manner. A tapered hole for inserting the movable taper pin 411 is provided above the short pendulum positioning bearing sleeve 419. When the movable taper pin 411 is inserted into the tapered hole, it becomes a single pendulum device, i.e., the long pendulum rod A47 and the short pendulum rod B423 become a whole, and simultaneously do a single pendulum motion around the long pendulum main shaft 44. When the movable taper pin 411 is pulled out of the tapered hole, it becomes a double pendulum device, i.e., the short pendulum rod B423 can swing freely to the left and right sides around the short pendulum support shaft 422. However, the swing amplitude can only be within the range of 90 degrees to the left and right, because when the short pendulum rod B423 swings up to a position at an angle of 90 degrees with the long pendulum rod A47, the short pendulum positioning block 431 will be blocked by the two sides of the sliding sleeve 416 at the lower end of the taper pin, so that it can no longer continue to swing up. Two symmetrical short pendulum rods B423 are welded below the short pendulum positioning bearing sleeve 419. The short pendulum rods B423 are fixedly connected to the cabin 424 (i.e., the heavy ball) below. The length of the short pendulum is L2. Immediately above the short pendulum positioning bearing sleeve 419, a corresponding sliding sleeve square hole 434 for fixing the lower end sliding sleeve 416 of the cone pin is opened on the long pendulum rod A47. Two sliding sleeve caps 415 are placed outside the lower end sliding sleeve square hole 434 to fix the lower end sliding sleeve 416 of the cone pin on the long pendulum rod A47. The lower end journal of the movable cone pin 411 can slide freely up and down in the hole in the middle of the lower end sliding sleeve 416 of the cone pin. Located above the lower end sliding sleeve square hole 434, a moving rod rectangular hole 413 for the cone pin moving rod 427 to move up and down is opened on the long pendulum rod A47. The movable cone pin 411 is fixedly connected to the cone pin movable rod 427 through the movable rod screw 428, and collision rollers 412 are respectively installed on the two symmetrical movable rod shaft heads 414 extending out of the movable rod rectangular hole 413. Two groups of collision arc seats 417 are symmetrically arranged below it, and a vertically installed large force storage spring 418 is respectively fixed just below the middle part, and large force storage springs 418 are respectively installed obliquely at both ends of the collision arc seat 417 to reduce the left and right swing amplitude of the collision arc seat 417 when it is hit by the collision roller 412. The lower ends of the large force storage springs 418 are fixedly connected to the frame. Inclined guide rails 433 are respectively installed above the two sides of the end of the collision arc seat 417, and the back side thereof is fixedly connected to the frame.When the collision roller 412 rolls from the upper end to the lower end of the inclined guide rail 433, due to the gradual reduction of the radius of its lower end, the cone pin moving rod 427 begins to gradually rise, and the cone pin small spring 426 sleeved outside the largest journal in the middle of the moving cone pin 411 is gradually compressed to the shortest size (i.e., it can no longer be compressed). At this time, the moving cone pin 411 has been pulled out of the corresponding cone pin hole. Since the weight of the moving cone pin 411 is very light, the elastic force of the cone pin small spring 426 is also very small, and the resistance generated is also very small, which has little effect on the speed of the swing movement of the cabin 424. Because the elastic force of the cone pin small spring 426 is very small, the large spring for storing power is not compressed at this time, and then the collision roller 412 begins to collide with the collision arc seat 417. Since the mass of the heavy ball is very large, and the heavy ball is close to the lowest position at this time, its swing speed is also very fast, and the swing radius (the swing radius is L1+L2 at this time) becomes longer, the impact force at this time is correspondingly large, and the large spring for storing power 418 at this time begins to be compressed under this huge impact force. During the collision, the friction force generated has a certain influence on the swing speed of the long pendulum A47, but the swing speed of the cabin 424 is not affected. The reason is that before the collision, the moving pin 411 has been pulled out of the corresponding tapered hole, and the long pendulum A47 and the short pendulum B423 have been transformed into a double pendulum device. At this time, the short pendulum B423 can swing freely around the short pendulum support shaft 422. When the collision roller 412 and the collision arc seat 417 begin to collide, the swing speed of the long pendulum A47 lags a little, but the cabin 424 still swings forward quickly around the short pendulum support shaft 422 at the original speed with the short pendulum B423 as the radius. When the short swing rod B423 swings up to form a 90 degree angle with the long swing rod A47, the short swing positioning block 431 collides with the side of the sliding sleeve 416 at the lower end of the cone pin, and the short swing rod B423 cannot swing up any further at this time. Under the action of the inertial force, the cabin 424 drives the short swing rod B423 and the long swing rod A47 to swing up together around the long swing main axis 44 while maintaining a 90 degree angle. Fig.25 As shown, the length of the swing arm at this time is the shortened swing rod C439, and its length is (i.e. the length of the hypotenuse of the right triangle). The length of the extended pendulum rod for the previous downward swing movement was L1+L2, which is much longer than the arm length of the shortened pendulum rod C439 for the current upward swing movement.

[0079] See also Figure 20-21On the taper pin moving rod 427, outside the middle step of the moving taper pin 411, a small taper pin spring 426 is sleeved, and its upper end is against the bottom plane of the outer taper pin sliding sleeve 425. The small journal at the top of the moving taper pin 411 can slide freely up and down in the center hole of the outer taper pin sliding sleeve 425. The outer taper pin sliding sleeve 425 is screwed into the inner taper pin sliding sleeve seat 410, and is fixed by the taper pin sliding sleeve and cap 48 on the top. At the same time, the upper and lower distances of the outer taper pin sliding sleeve 425 can be adjusted. A sliding sleeve seat square hole 432 for fixing the inner taper pin sliding sleeve seat 410 is opened at the corresponding position of the long swing rod A47, and two sliding sleeve seats and caps 49 are provided. Outside the sliding sleeve seat square hole 432, the inner taper pin sliding sleeve seat is fixed on the long swing rod A47.

[0080] Before the large force storage spring 418 is compressed, that is, before the collision roller 412 collides with the collision arc seat 417, the long pendulum square sleeve 41 is suspended on the square slider 42 under the action of gravity, and the weight of the entire swing device is supported by the long pendulum main shaft 44. Before the collision occurs, under the action of the inclined guide rail 433, the small cone pin spring 426 has been compressed to the shortest size. When the collision roller 412 and the collision arc seat 417 begin to collide, the cone pin moving rod 427 continues to rise. At this time, the small cone pin spring 426 can no longer be compressed, so it moves upward along the sleeve ball 430 against the long pendulum square sleeve 41 through the cone pin sleeve 425 above. When the long pendulum rod A47 swings down to a vertical position, that is, the lowest position of the heavy ball, as shown in FIG. Fig.24 As shown, at this time, there is a gap H between the long pendulum square sliding sleeve 41 and the square slider 42, that is, at this time, the weight of the entire swing device is not hung on the long pendulum main shaft 44, but is supported by the large force storage spring 418, see Figure 20-21 At this time, the impact force and centrifugal force of the cabin 424 when it swings down are transmitted to the large force storage spring 418 through the short swing support shaft 422, and then through the cone pin moving rod 427, the collision roller 412 and the collision arc seat 417. These forces compress the large force storage spring 418. Fig.24 , the compressed length is L. HL = 1-5mm, in other words, when the cabin 424 swings down to the lowest position, there is a 5mm gap between the upper inner side of the long pendulum square sliding sleeve 41 and the upper outer side of the square slider 42. By adjusting the external taper pin sliding sleeve 425 and the taper pin sliding sleeve cap 48, the gap between the long pendulum square sliding sleeve 41 and the square slider 42 can be controlled to be about 1mm. In other words, as long as the long pendulum main shaft 44 is not subjected to force, the smaller the gap, the better.

[0081] The working principle of this embodiment is introduced below:

[0082] See also Fig. 22As can be seen from the figure, the movable cone pin 411 has been inserted into the corresponding cone hole under the action of the cone pin small spring 426. At this time, the long pendulum A47 and the short pendulum B423 become a whole, and together do a single pendulum motion around the long pendulum main axis 44. At this time, the total length of the pendulum is the long pendulum A47 plus the short pendulum B423, that is, L1+L2, which is referred to as the extended pendulum below. Before starting, if Fig. 22 As shown, firstly, the cabin 424 is lifted upwards over the horizontal line by external force, and is ready to swing downwards. At this time, the inner and outer sides of the long pendulum square sliding sleeve 41 and the top of the square slider 42 are tightly attached together, that is, the weight of the heavy ball and the entire swing device are supported by the long pendulum main shaft 44. When the cabin 424 swings downwards, the cabin 424 swings downwards in a counterclockwise direction around the center of the long pendulum main shaft 44 with the extended pendulum rod as the radius. When the cabin 424 is lifted upwards by external force, the short pendulum limit roller 437 installed on the short pendulum rod B423 pushes the movable inclined pressure plate 435 upwards, so that the movable inclined pressure plate 435 swings upwards in an arc around the pressure plate fixed rotating shaft 438. At this time, the pressure plate spring 440 movably connected to the upper side thereof is compressed, and the iron core 5 of the telescopic electromagnet 1 movably connected to the lower side thereof is pulled out a part of the length. When the external force lifts the extended swing rod just above the horizontal position, the external force pushing the cabin 424 upward is removed. Under the action of gravity and the elastic force of the pressure plate spring 440, the cabin 424, together with the extended swing rod, begins to swing downward with a relatively large initial speed around the center of the long swing main shaft 44. At this time, the contact switch one-way bumper 441 swings upward, and the upper plane of its inclined end surface collides with the bumper of the first relay (not shown in the figure), and the power supply of its magnetic coil is turned on. At this time, the first AC contactor (not shown in the figure) starts to work and connects the telescopic electromagnet 1 to a 380-volt power supply. At this time, the iron core quickly attracts and quickly pulls the movable inclined pressure plate 435 downward, and assists the cabin 424 to swing downward quickly through the short swing limit roller 437.

[0083] See also Fig.23 When the cabin 424 swings down to the point where the collision roller 412 just touches the upper end of the inclined guide rail 433, the small cone pin spring 426 has not been compressed yet, and the movable cone pin 411 is still inserted in the corresponding cone hole. When the collision roller 412 rolls to the lower end of the inclined guide rail 433, since its R is a constant velocity helix, the radius is shortened by a corresponding size, and the small cone pin spring 426 is compressed upward, and the movable cone pin 411 is pulled out of the corresponding cone hole. Fig.23As shown. Because the elastic force of the small cone pin spring 426 is not large, the friction resistance of the collision roller 412 has little effect on the swing speed of the cabin 424. At this time, the swing device changes from a single pendulum structure to a double pendulum structure, and the top inner side of the long pendulum square sliding sleeve 41 and the top outer side of the square slider 42 are still attached together, that is, the entire weight is still supported by the long pendulum main shaft 44. Then the collision roller 412 collides with the collision arc seat 417. At this time, the cabin 424 swings down from the horizontal position to a nearly vertical position (i.e., close to the lowest position). At this time, the total length of the extended pendulum is L1+L2. Assuming L1=1.5 meters and L2=0.5 meters, the total length of the extended pendulum is L1+L2=2 meters. At this time, when the cabin 424 swings to the lowest position, its final velocity is 6.26m / S, and the impact force is about 6 times the mass of the heavy ball. Its centrifugal force (that is, the pulling force of the heavy ball on the pendulum) is also about 3 times the mass of the heavy ball. These are indeed two large kinetic energies.

[0084] The following describes how the present invention utilizes these two kinetic energies to do work.

[0085] When the collision roller 412 collides with the collision arc seat 417, the cabin 424 is close to the lowest position, and its swing speed is very fast. In addition, the mass of the cabin 424 is very large, and the impact force is naturally very large. At this time, the large force storage spring 418 begins to be compressed. As the collision roller 412 rolls toward the center of the collision arc seat 417 (i.e., the highest point of the convex arc), the degree of compression of the large force storage spring 418 increases. At this time, the long pendulum square sliding sleeve 41 gradually rises until a gap appears between it and the square slider 42. At this time, the long pendulum main shaft 44 does not support any weight. At this time, the impact force and centrifugal force are transferred from the collision roller 412 to the large force storage spring 418 through the collision arc seat 417. There is no additional friction resistance during the collision process, and only the friction force of the upper main shaft bearing 46 is transferred to the lower collision roller 412. It is just that the friction distance of the rolling wheel 412 is slightly longer than that of the main shaft bearing 46, so that the swing speed of the long swing rod A47 lags slightly behind the swing speed of the short swing rod B423. At this time, the swing speed of the cabin 424 is not affected at all, because the cabin 424 is an independent short swing device unrelated to the long swing rod A47. At this time, the cabin 424 and the short swing rod B423 swing rapidly in the counterclockwise direction at the original speed around the short swing support shaft 422.

[0086] See also Fig.24When the long pendulum beam A47 swings to the vertical position, the cabin 424 has already swung forward by about 60 degrees. At this time, the collision roller 412 has already run to the highest position of the collision arc seat 417, and the height to which the long pendulum square sleeve 41 rises along the sleeve ball 430 is H. Part of the impact force generated when the cabin 424 swings down past the vertical position (i.e., the lowest position) is directly transferred from the collision arc seat 417 to the large force storage spring 418 and compresses it. All the pulling force (centrifugal force) generated by the cabin 424 on the short pendulum beam B423 is also transferred to the large force storage spring 418 and compresses it through the short pendulum support shaft 422, the collision roller 412, and the collision arc seat 417. Under this dual force, the height to which the large force storage spring 418 drops after being compressed is L. As Fig.24 As shown, the distance L between the collision arc seat 417 and the inclined guide rail 433 is the height to which the large force storage spring 418 drops after being compressed. At this time, the convex arc of the collision arc seat 417 lifts the long pendulum square sleeve 41 up to a height of H, and the length to which the large force storage spring 418 is compressed downward is L, HL=5mm. As a result, there is still a gap of 5mm, which can be reduced to about 1mm by fine-tuning the external tap pin sleeve 425 and the taper pin sleeve and cap 48, that is, the long pendulum square sleeve 41 is not pressed on the square slider 42. At this time, the long pendulum rod A47 has a certain lag in its swing speed in the counterclockwise direction, but the cabin 424 together with the short pendulum rod B423 still moves rapidly in the counterclockwise direction around the center of the short pendulum positioning bearing sleeve 419 at the original speed. As shown Fig.24As shown in the figure, when the long swing rod A47 swings to the vertical position, the short swing rod B423 has advanced by about 45 degrees. At this time, the main shaft bearing 46 above the machine is not subjected to force, but is transferred to the two symmetrical collision rollers 412 below, and the entire device does not increase new friction resistance. At this time, all the external forces borne by the collision roller 412 are transmitted to the large force storage spring 418 through the collision arc seat 417 and stored in the form of elastic potential energy. After the collision roller 412 rolls over the highest position (i.e., after the long pendulum rod A47 swings over the vertical position), the long pendulum square sliding sleeve 41 quickly presses onto the square slider 42 (because the taper pin sliding sleeve and the cap 48 have already adjusted their gap to the minimum size), at this time, all gravity is supported by the long pendulum main shaft 44, and there is no more pressure on the large spring 418, at this time, all the elastic potential energy stored is converted into elastic kinetic energy and released, pushing the collision arc seat 417 to rise rapidly, at this time, the collision roller 412 slides rapidly from the center to the edge along the convex arc on the collision arc seat 417, and is superimposed with the original swing speed of the long pendulum, so that it can obtain a higher swing speed in the counterclockwise direction. At this time, the present embodiment uses part of the impact force of the heavy ball and all the centrifugal force (i.e., the total pulling force of the heavy ball on the swing rod) to do work. It can also be seen from the figure that the swing speed of the short pendulum B423 is faster than that of the long pendulum A47. When the long pendulum A47 is in the vertical position, the short pendulum B423 has already swung ahead by 45 degrees.

[0087] See also Fig.25 As can be seen from the figure, the collision roller 412 has rolled to the rightmost side of the collision arc seat 417, and the elastic kinetic energy has been completely released. The large force storage spring 418 has returned to its normal height before being compressed. At this time, the long pendulum square sliding sleeve 41 is still pressed on the square slider 42, and the weight of the entire device is supported by the long pendulum main shaft 44. Under the action of inertia, the cabin 424, together with the short pendulum rod B423, swings counterclockwise around the short pendulum support shaft 422 to a position perpendicular to the long pendulum rod A47. At this time, due to the collision between the short pendulum positioning block 431 and the side of the sliding sleeve 416 at the lower end of the cone pin, the cabin 424 cannot continue to swing upward around the short pendulum support shaft 422. Due to the effect of inertia, the cabin 424 drives the short pendulum B423 and the long pendulum A47 together, and maintains an angle of 90 degrees, and continues to swing counterclockwise around the center of the long pendulum main axis 44. At this time, the whole device returns to the form of a single pendulum, except that the long section of the pendulum is shown by the dotted line 439. At this time, it is called the shortened pendulum C439, and its length is It is much shorter than the extended swing length L1+L2.

[0088] See also Fig. 22When the heavy ball starts to swing downward, the cabin 424 has a large initial velocity when it swings downward due to the assistance of the pressure plate spring 440 and the large pulling force generated by the telescopic electromagnet 1 after it is connected to the 380V power supply. Fig.25 In addition, when the cabin 424 starts to swing upward, the torque of the negative force of gravity during the upward swing is reduced due to the assistance of the large force storage spring 418 and the shortening of the swing arm length. At this time, after the cabin 424 swings to the lowest position, it swings upward counterclockwise at a faster speed.

[0089] Please refer to Fig.26 , when the center of the cabin 424 swings up to the horizontal position, the long swing rod A47 is still at a certain angle ∝ from the horizontal position, and the pressure plate spring 440 movably connected to the movable inclined pressure plate 435 is in a relaxed state, and its length is the longest dimension. Under the gravity of the movable inclined pressure plate 435 swinging down around the pressure plate fixed shaft 438, the iron core 5 of the telescopic electromagnet 1 movably connected thereto is pressed to the lowest position. At this time, the contact switch one-way bumper 441 swings up to the highest position, and its inclined end does not contact the bumper of the first relay or the second relay (not shown in the figure). When the short swing limit roller 437 set on the short swing rod B423 collides with the movable inclined pressure plate 435 tilted at 45 degrees, the short swing limit roller 437 slides obliquely to the right along the direction of the movable inclined pressure plate 435, and the cabin 424 swings to the right in an approximately horizontal direction. At this time, the long swing rod A47 swings up in the counterclockwise direction around the long swing main axis 44. At this time, the angle between the short pendulum rod B423 and the long pendulum rod A47 gradually increases, and as the above movement is made, the angle becomes larger and larger. Fig. 27 At this time, under the action of the small cone pin spring 426, the cone head of the movable cone pin 411 slides on the outer circle of the short pendulum positioning bearing sleeve 419 toward the cone hole direction, see Fig.21 , until it is inserted into the corresponding tapered hole. At this time, the long pendulum A47 and the short pendulum B423 become a whole again, and the total length of the entire pendulum becomes an extended pendulum, that is, the length is L1+L2. At this time, the iron core of the telescopic electromagnet 1 is pulled upward for a short distance, and the pressure plate spring 440 is also compressed to a certain extent. The contact switch one-way bump block 441 also swings downward to a certain arc, and its inclined surface contacts the corresponding bump block of the corresponding first relay. At this time, as long as the contact switch one-way bump block 441 swings upward, the magnetic coil of the first relay can be connected to the power supply, and the 380V AC contactor can be started to supply power to the telescopic electromagnet 1.

[0090] Due to the various assisting factors mentioned above, after the cabin 424 is swung up to a horizontal position, see Fig. 27, there is still a large inertia force to continue the counterclockwise upward swing movement, and the inclined movable pressure plate 435 continues to swing upward clockwise around the pressure plate fixed shaft 438 under the push of the short swing limit roller 437. At this time, the pressure plate spring 440 is further compressed, and the iron core 5 of the telescopic electromagnet 1 is correspondingly pulled outward for a distance. At this time, the contact switch one-way bumper 441 swings downward clockwise around the pressure plate fixed shaft 438, and the contact switch one-way bumper 441 does not contact the bumper of the first relay (not shown in the figure), so the first relay has not yet worked.

[0091] See also Fig.28 , when the long swing rod A47 swings over the horizontal line and continues to swing counterclockwise for a certain arc, the upward swinging movement stops when the inertial force of the upward swinging is equal to the elastic force of the pressure plate spring 440. At this time, the iron core 5 of the telescopic electromagnet 1 has been fully extended. At this time, the one-way bump block 441 of the contact switch swings down to the lowest position, and its inclined end face collides with the bump block of the second relay (not shown in the figure). When it swings up again, the magnetic coil of the second relay will be connected to the power supply. At this time, the pressure plate spring 440 has been further compressed and has stored a large amount of elastic potential energy. When the cabin 424 swings down in the clockwise direction under the action of gravity, the elastic potential energy of the pressure plate spring 440 is fully released and converted into kinetic energy, which pushes the cabin 424 to accelerate the clockwise downward swinging movement through the tilting movable pressure plate 435 and the short swing limit roller 437. At this time, the one-way contact block 441 of the contact switch swings clockwise, and its end plane moves the contact block of the second relay (not shown in the figure), energizing its magnetic coil, and causing the second AC contactor (not shown in the figure) to start working, and connect the telescopic electromagnet 1 to the 220V power supply, while also disconnecting the normally closed contact of the first relay magnetic coil. At this time, the iron core 5 of the telescopic electromagnet 1 quickly closes, assisting the cabin 424 to swing down quickly. Since the elastic potential energy stored in the pressure plate spring 40 increases at this time, the power of the telescopic electromagnet 1 can be reduced accordingly, so the original 380V power supply is replaced with a 220V power supply at this time, thereby saving energy consumption of the entire device.

[0092] With the help of the pressure plate spring 440 and the telescopic electromagnet 1, the cabin 424 starts to swing down clockwise at a large initial speed. When the long swing rod A47 swings down to the horizontal position, the end plane of the contact switch one-way bump block 441 contacts the bump block of the 380V first relay, so that the circuit of its magnetic coil is connected. However, since its normally closed contact is disconnected, the first relay cannot work. At this time, the cabin 424 swings down clockwise at a very fast speed, and the collision roller 412 collides with the inclined guide rail 433 on the right again..., thus repeating the above-mentioned movement process, but the swing direction is opposite, but the movement principle is the same, which will not be repeated.

[0093] If there is no lifting device such as long pendulum square sliding sleeve 1:

[0094] 1. After the large force storage spring 418 is compressed, its pressure is transmitted to the main shaft bearing 46 through the long pendulum rod A47 and other parts, which increases its friction resistance and slows down the swing speed. Even the long pendulum rod A47 is stuck before it swings down to the vertical position, not to mention using the impact force of the cabin 424 to do work.

[0095] 2. The pulling force when the heavy ball swings down is also transmitted to the long pendulum main shaft 44 through the long pendulum rod A47. Because the long pendulum rod A47 cannot be stretched, the large spring 418 cannot be compressed, and the centrifugal force when the cabin 424 swings down cannot be used to do work.

[0096] In summary, this embodiment has the following three key technologies:

[0097] 1. This embodiment combines a single pendulum device and a double pendulum device in an orderly manner, so that the swing arm of the heavy ball extends when the heavy ball swings downward, and shortens when the heavy ball swings upward. This increases the torque of gravity doing work during the downward swing, and reduces the torque of gravity doing negative work during the upward swing, thereby achieving the purpose of saving driving power.

[0098] 2. This embodiment uses the centrifugal force of the swing ball on the swing rod to do work. In the existing single pendulum device, the pulling force of the swing ball on the swing rod cannot do work. Because the direction of the pulling force is always perpendicular to the direction of the swing ball. This embodiment cleverly designs the structural form of the long pendulum square sliding sleeve 41 and the square slider 42. When the swing ball swings to the bottom position and the pulling force on the swing rod is the largest, the long pendulum square sliding sleeve 41 moves upward for a short distance under the action of the collision roller 412 and related parts. At this time, all gravity does not fall on the long pendulum main shaft 44, but is all pressed on the large force storage spring 418. The present invention converts it into elastic potential energy and stores it. When the swing rod just swings past the vertical position, the long pendulum square sliding sleeve 41 immediately drops and hangs on the square slider 42 again. At this time, the weight of the entire swing device is fully supported by the long pendulum main shaft 44. At this time, the elastic potential energy stored in the large force-storing spring 418 is completely released and converted into kinetic energy, which helps the cabin 424 to swing upward quickly, and no new friction resistance is added at this time, thus achieving the purpose of increasing its upward swing amplitude.

[0099] 3. The present embodiment also utilizes the impact force when the swing ball is swinging down to do work. In the existing dynamic single pendulum device, the impact force cannot be utilized to do work, because when the swing ball is doing the swinging motion, no matter what object the swing ball hits, its swing speed will slow down or even stop. The present embodiment cleverly adopts the key technology of single and double pendulum timing conversion. When the swing ball swings downward from a height, the whole device is a single pendulum structure at this moment, so the swing arm is long, the swing speed is large, and its impact force is naturally also very large. Before the swing ball is about to collide with the spring seat, the whole device is transformed from a single pendulum into a double pendulum structure. After the collision occurs, the swing ball still swings forward at the original speed, and its swing speed is not affected. At this moment, the impact force compresses the large spring 418 for storing power, and the stored pressure potential energy will be released when doing the upward swing motion, and is transformed into the power that promotes the heavy ball to swing up quickly.

[0100] Due to the above advantages, this embodiment reduces driving power, saves energy consumption and reduces operating costs.
