[0056] The core of the present invention is to provide a capacitor transport and replacement device, which can automatically transport capacitors to corresponding positions without manual operation and has more flexible position movement.

[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Figure 1 This is a structural schematic diagram of a capacitor transport and replacement device provided by the present invention, the capacitor transport and replacement device comprises a base 1, a roller 2, a driving device 3, a telescopic device 4 and a fixing device 5;

[0059] A roller 2 and a driving device 3 are arranged below the base 1, and a telescopic device 4 and a fixing device 5 are arranged above the base 1;

[0060] The power supply end of the driving device 3 is connected to a power source, the first output end of the driving device 3 and the driving end of the roller 2 are used to drive the roller 2 to roll so as to drive the capacitor carrying and replacing device to run on the ground, and the second output end is connected to the driving end of the telescopic device 4, and is used to drive the telescopic device 4 to telescope up and down in a direction perpendicular to the ground so as to raise and lower the capacitor;

[0061] The fixing device 5 is connected to the top of the telescopic device 4 and is used to fix the capacitor on the top of the telescopic device 4 .

[0062] The roller 2 is arranged below the base 1. When the roller 2 rolls, the entire capacitor transport and replacement device will move accordingly to transport the capacitor to the target position. However, the installation height of the capacitor may be far from the ground, so a telescopic device 4 is also required to lift the capacitor to the target height. Since the capacitor will move back and forth and rise on the capacitor transport and replacement device, a fixing device 5 is required to fix the capacitor to prevent it from falling during transportation. The driving device 3 arranged below the base 1 is used to drive the roller 2 to roll to change the position of the capacitor, and drive the telescopic device 4 to extend and retract up and down to change the height of the capacitor.

[0063] Furthermore, considering that the capacitor transport and replacement device is constantly moving, the power source for powering the drive device 3 can be set to a portable power source, such as a battery.

[0064] The present application provides a capacitor transport and replacement device, which relates to the field of transportation, and includes a base 1, a roller 2, a driving device 3, a telescopic device 4 and a fixing device 5; the roller 2 and the driving device 3 are arranged below the base 1, and the telescopic device 4 and the fixing device 5 are arranged above the base 1; the power supply end of the driving device 3 is connected to the power supply, the first output end of the driving device 3 is connected to the driving end of the roller 2, and the roller 2 is driven to roll so as to drive the capacitor transport and replacement device to run on the ground, and the second output end is connected to the driving end of the telescopic device 4, and the telescopic device 4 is driven to telescope up and down in a direction perpendicular to the ground so as to raise and lower the capacitor; the fixing device 5 is connected to the top of the telescopic device 4. The driving device 3 drives the roller 2 to rotate to drive the entire device to move to the corresponding position, and then drives the telescopic device 4 to lift the capacitor to the target height, and the fixing device 5 fixes the capacitor to prevent the capacitor from falling. The present application can automatically transport the capacitor to the corresponding position without manual operation, and the position movement is more flexible.

[0065] Based on the above embodiments:

[0066] Figure 2 A schematic diagram of the structure of another capacitor transport and replacement device provided by the present invention;

[0067] Figure 3 A schematic diagram of the structure of a three-star wheel provided by the present invention;

[0068] In some embodiments, the roller 2 includes a three-star wheel 21 and a universal wheel 22;

[0069] The three-star wheel 21 is arranged at one end below the base 1, and the universal wheel 22 is arranged at the other end below the base 1;

[0070] The three-star wheel 21 is used to support and buffer the movement of the capacitor transport and replacement device, and the universal wheel 22 is used to support and rotate the capacitor transport and replacement device.

[0071] The base 1 provides support for the entire device, with a lockable universal wheel 22 installed at one end of the bottom, and the other end is used to fix the motor and the reducer, and a pulley linkage telescopic mechanism and a push handle are installed on the top.

[0072] The brackets of the three-star wheel 21 are installed on both sides of the bottom of the device, and the universal wheel 22 is installed at the other end of the device to provide support and rotation capability for the entire device. The universal wheel 22 has a locking function. When the device reaches the appropriate position, the locking universal wheel 22 prevents the device from deflecting.

[0073] The three-star wheel 21 is arranged at the front end of the base 1 along the traveling direction, and the universal wheel 22 is arranged at the rear end of the base 1 along the traveling direction.

[0074] In some embodiments, the three-star wheel 21 includes a frame and three tires;

[0075] The center of the bracket is connected to the bottom of the base 1, and the three tires are respectively arranged on the three supporting points of the bracket;

[0076] When crossing an obstacle, the bracket is used to rotate along the center and the three tires are used to keep it still. When walking on a flat road, any two of the three tires are used to rotate and the bracket is used to keep it still.

[0077] The bracket and tire are the parts of the whole device that approach and contact obstacles (such as steps, trenches, etc.). The bracket is installed on both sides of the bottom of the device, and three tires are connected to each side corner. When the driving device 3 generates power, the bracket and tire cross the obstacle by rotating. When the three-star wheel 21 crosses the obstacle, the tire plays a supporting and buffering role. At this time, the tire does not rotate, but the bracket rotates; after climbing over the obstacle, during the human propulsion stage, the tire rotates, but the bracket does not rotate. The advantage of using the three-star wheel 21 is that the bracket can provide the ability to climb obstacles, and any two tires of the three-star wheel 21 can provide driving force when the road is flat.

[0078] In some embodiments, a worm gear reducer 6 is also included;

[0079] The worm gear reducer 6 includes an input shaft and an output shaft, the input shaft and the output shaft are meshed through gears, and the number of teeth of the gear of the input shaft is less than the number of teeth of the gear of the output shaft;

[0080] The input shaft is connected to the driving device 3, and the output shaft is connected to the three-star wheel 21 for speed reduction.

[0081] The bracket of the three-star wheel 21 is made of metal and connected to the worm gear reducer 6 through a bearing. The worm gear reducer 6 reduces the speed of the high-speed power generated by the DC motor by meshing the gear with a small number of teeth on the input shaft with the large gear on the output shaft. It is installed at the bottom of the special base 1, the input shaft is connected to the DC forward and reverse motor, and the output shaft is connected to the bracket of the three-star wheel 21.

[0082] In some embodiments, an energy storage device 7 is also included;

[0083] The energy storage device 7 is a power source connected to the power supply end of the driving device 3 and is used to supply power to the driving device 3 during the operation of the capacitor transport and replacement device.

[0084] The energy storage device 7 is installed at the bottom of the special base 1, and supplies power to the DC forward and reverse motor, the roller 2 and the telescopic device 4, and has a charging function. The energy storage device 7 can be a battery.

[0085] Figure 4 A schematic structural diagram of a driving device provided by the present invention;

[0086] In some embodiments, the driving device 3 includes a first controllable switch KM1, a second controllable switch KM2, a third controllable switch KM3, a fourth controllable switch KM4, a roller 2 driving motor M1 and a telescopic device 4 driving motor M2;

[0087] The first controllable switch KM1, the second controllable switch KM2, the third controllable switch KM3 and the fourth controllable switch KM4 each include two contacts that act simultaneously;

[0088] The first end of the first contact of the first controllable switch KM1 and the first end of the first contact of the second controllable switch KM2 are both connected to the positive output end of the energy storage device, the second end of the first contact of the first controllable switch KM1 is respectively connected to the positive power supply electrode of the roller 2 driving motor M1 and the first end of the second contact of the second controllable switch KM2, the second end of the first contact of the second controllable switch KM2 is respectively connected to the negative power supply electrode of the roller 2 driving motor M1 and the first end of the second contact of the first controllable switch KM1, and the second end of the second contact of the first controllable switch KM1 and the second end of the second contact of the second controllable switch KM2 are both connected to the negative output end of the energy storage device;

[0089] When the two contacts of the first controllable switch KM1 are closed and the two contacts of the second controllable switch KM2 are disconnected, the roller 2 drives the motor M1 for forward rotation; when the two contacts of the first controllable switch KM1 are disconnected and the two contacts of the second controllable switch KM2 are closed, the roller 2 drives the motor M1 for reverse rotation;

[0090] The first end of the first contact of the third controllable switch KM3 and the first end of the first contact of the fourth controllable switch KM4 are both connected to the positive output end of the energy storage device, the second end of the first contact of the third controllable switch KM3 is respectively connected to the positive power supply electrode of the telescopic device 4 drive motor M2 and the first end of the second contact of the fourth controllable switch KM4, the second end of the first contact of the fourth controllable switch KM4 is respectively connected to the negative power supply electrode of the telescopic device 4 drive motor M2 and the first end of the second contact of the third controllable switch KM3, and the second end of the second contact of the third controllable switch KM3 and the second end of the second contact of the fourth controllable switch KM4 are both connected to the negative output end of the energy storage device;

[0091] When the two contacts of the third controllable switch KM3 are closed and the two contacts of the fourth controllable switch KM4 are disconnected, the telescopic device 4 drives the motor M2 for forward rotation; when the two contacts of the third controllable switch KM3 are disconnected and the two contacts of the fourth controllable switch KM4 are closed, the telescopic device 4 drives the motor M2 for reverse rotation.

[0092] In some embodiments, the driving device 3 further includes an air switch S3, a voltage dividing resistor R1, a first reset switch S1 and a second reset switch S2;

[0093] The first end of the air switch S3 is connected to the positive output end of the energy storage device, the second end of the air switch S3 is respectively connected to the first end of the voltage-dividing resistor R1, the first end of the first reset switch S1 and the first end of the second reset switch S2, the second end of the voltage-dividing resistor R1 is connected to the negative output end of the energy storage device, the second end of the first reset switch S1 is connected to the first end of the first contact of the first controllable switch KM1, and the second end of the second reset switch S2 is connected to the first end of the first contact of the third controllable switch KM3;

[0094] The air switch S3 is used to disconnect the driving device 3 , the first reset switch S1 is used to control the power supply of the motor of the roller 2 , and the second reset switch S2 is used to control the power supply of the driving motor M2 of the telescopic device 4 .

[0095] The DC in the figure is the DC power supply output by the energy storage device. A power management integrated chip is welded to feedback the battery status, charge and discharge rate, etc. The air switch S3 is responsible for breaking the entire circuit; the voltage-dividing resistor R1 is used to share the excess voltage to ensure that the voltage on both sides of the drive motor is the rated value; the first reset switch S1 is a self-reset rebound switch. After the knob conversion switch selects the forward and reverse rotation of the motor, pressing the first reset switch S1 can energize the roller 2 drive motor M1 and provide power for the three-star frame; the lifting drive module is the power part of the pulley linkage telescopic mechanism. The second reset switch S2 is a self-reset rebound switch. After the knob conversion switch selects the forward and reverse rotation of the motor, pressing the second reset switch S2 can energize the telescopic device 4 drive motor M2 and provide power for the pulley lifting. ; The knob conversion switch of the traveling module includes two pairs of contacts, the first controlled switch KM1 and the second controlled switch KM2. When the first controlled switch KM1 is switched to the normally closed state and the second controlled switch KM2 is switched to the normally open state, the current flows into the positive pole and flows out of the negative pole of the roller 2 driving motor M1 for forward rotation. Otherwise, the roller 2 drives the motor M1 to reverse. Similarly, the knob conversion switch of the lifting module includes two pairs of contacts, the third controlled switch KM3 and the fourth controlled switch KM4. When the third controlled switch KM3 is switched to the normally closed state and the fourth controlled switch KM4 is switched to the normally open state, the telescopic device 4 drives the motor M2 for forward rotation. Otherwise, the telescopic device 4 drives the motor M2 for reverse rotation.

[0096] Figure 5 A schematic structural diagram of a telescopic device provided by the present invention;

[0097] In some embodiments, the telescopic device 4 includes a motor 41, a hydraulic push rod 42, a first pulley 43, a second pulley 44, a third pulley 45, a fourth pulley 46, a first-level mechanism 47, a second-level mechanism 48, a third-level mechanism 49, a fourth-level mechanism 410, a first connecting line 411, a second connecting line 412 and a third connecting line 413;

[0098] The first-stage mechanism 47 and the motor 41 are fixed on the top of the base 1, and the hydraulic push rod 42 is fixed on the top of the motor 41. The motor 41 is used to control the lifting and lowering of the hydraulic rod;

[0099] The first pulley 43 is arranged on the top of the hydraulic rod;

[0100] The second pulley 44 is arranged at a second preset height of the hydraulic rod from the motor 41;

[0101] The third pulley 45 is disposed on the top of the fourth-level mechanism 410;

[0102] The fourth pulley 46 is arranged at the bottom of the second stage mechanism 48;

[0103] The bottom of the second stage mechanism 48 is connected to a first fixed point Q1 of the hydraulic rod at a first preset height from the motor 41, and the second preset height is higher than the first preset height;

[0104] The two ends of the first connecting line 411 are respectively fixed to the second fixed point Q2 at the bottom of the third-stage mechanism 49 and the third fixed point Q3 on the motor 41, and are wound around the first pulley 43;

[0105] The two ends of the second connecting line 412 are respectively fixed to the fourth fixing point Q4 at the bottom of the third and the fifth fixing point Q5 at the top of the hydraulic push rod 42, and pass around the second pulley 44 and the third pulley 45 in sequence;

[0106] Two ends of the third connecting line 413 are respectively fixed to the sixth fixed point Q6 at the top of the first-stage mechanism 47 and the seventh fixed point Q7 at the bottom of the fourth-stage mechanism 410, and are wound around the fourth pulley 46;

[0107] The hydraulic push rod 42 is used to sequentially drive the second-stage mechanism 48 , the third-stage mechanism 49 and the fourth-stage mechanism 410 to rise or fall based on the control of the motor 41 .

[0108] The motor 41 controls the hydraulic rod to start and stop lifting. The first-level mechanism 47 is fixed to the special base 1 and is inactive. The second-level mechanism 48 is directly fixedly connected to the hydraulic rod (see the first fixed point Q1). When the hydraulic rod rises, the second-level mechanism 48 rises synchronously. The third-level mechanism 49 cooperates with the first pulley 43 by a line starting from the second fixed point Q2 and ending at the third fixed point Q3. When the hydraulic rod pushes the first pulley 43 to rise, the second fixed point Q2 pulls the third-level mechanism 49 to rise. The fourth-level mechanism 410 cooperates with the second pulley 44 and the third pulley 45 by a line starting from the fourth fixed point Q4 and ending at the fifth fixed point Q5. When the fifth fixed point Q5 at the top of the hydraulic rod rises, it drives the second pulley 44 to rise, indirectly causing the fourth-level mechanism 410 to rise. It can be seen that when the hydraulic rod rises, it pushes the second, third, and fourth-level mechanisms 410 to move simultaneously, but the inconsistent force action strokes lead to inconsistent movement speeds among the three-level mechanisms. Since it is directly connected to the hydraulic rod, the second stage mechanism 48 rises the fastest, responds to the rising torque first, and reaches its highest position first; by analogy, the third stage responds to the rising torque later than the second stage, and the fourth stage responds to the rising torque later than the third stage.

[0109] Similarly, when descending, the second-level mechanism 48 is still the first to respond to the descending torque and move downward first. While the second-level mechanism is moving, the third-level mechanism 49 is indirectly lowered through the fourth pulley 46 and the line connecting the sixth fixed point Q6 and the seventh fixed point Q7. During the descent of the hydraulic rod, the fifth fixed point Q5 and the second pulley 44 are simultaneously lowered, and the fourth fixed point Q4 of the third-level mechanism 49 is used to force the fourth-level mechanism 410 to descend. Therefore, when descending, the second-level mechanism 48 is directly lowered, the third-level mechanism 49 is lowered by the second-level mechanism 48, and the fourth-level mechanism 410 is lowered last by the second and third-level mechanisms.

[0110] Therefore, no matter whether the linkage mechanism is raised or lowered, the second-level mechanism 48 is always activated first and reaches its highest position first, followed by the third-level mechanism 49 and finally the fourth-level mechanism 410.

[0111] It should be noted that the first pulley 43 , the second pulley 44 , the third pulley 45 and the fourth pulley 46 are all fixed pulleys.

[0112] In some embodiments, further comprising a rotating bearing;

[0113] A rotation bearing is provided on the top of the fourth stage mechanism 410 for rotating to change the angle of the capacitor.

[0118] In some embodiments, the fixing device 5 includes a limiting rod 51, a limiting baffle 52, a limiting rod slide 53, a clamping plate 54 and a fixing bolt 55;

[0119] The two clamping plates 54 are arranged in parallel, the limiting rod slideway 53 is arranged between the two clamping plates 54 and perpendicular to the clamping plates 54, and the long side of the limiting rod 51 is placed along the limiting rod slideway 53 and slides on the limiting rod slideway 53;

[0120] The clamping plates 54 are provided with fixing bolts 55 for fixing the distance between the clamping plates 54;

[0121] The limiting baffle 52 is perpendicular to the limiting rod 51 and is fixedly arranged on a side of the limiting rod 51 away from the clamping plate 54. The limiting baffle 52 and the limiting rod 51 form an L-shaped structure.

[0122] Each limiting rod slideway 53 includes an upper slideway and a lower slideway, and both the upper slideway and the lower slideway are provided with an L-shaped structure. When the distance between the two clamping plates 54 reaches the farthest, the two limiting baffles 52 are tightly attached.

[0123] The clamping plate 54 provides a lock for adjusting the capacitor's posture and lifting it to prevent the capacitor from tilting or falling.

[0124] Figure 6 The figure shows the state when the distance between the two clamping plates 54 reaches the maximum, and the two limit baffles 52 are close together to play a role of locking. When the distance between the two clamping plates 54 reaches the minimum, the distance between the clamping plates 54 is at least the length of the limit rod 51. Therefore, the length of the limit rod 51 and the width of the baffle of the limit rod 51 directly affect the distance between the clamping plates 54.

[0125] When the fixing bolts are tightened, the distance between the two clamping plates 54 will no longer change, and the electric motor will no longer shake after the capacitor is clamped.

[0126] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
