Abstract

The vehicle carrier for the comb tooth exchange type parking equipment comprises a main frame with comb teeth, and a shear fork jacking device is arranged below each of the front part and the rear part of the main frame. Each shear fork jacking device comprises a first shear fork rod, a second shear fork rod, a long rocker and a short rocker, wherein the first shear fork rod and the second shear fork rod are combined, and the long rocker and the short rocker are arranged between the shear fork rods.

Compared with the prior art, a long bottom frame is omitted, the structure of a large part is simplified, the process and installation defects of a guide column and guide sleeve mechanism are avoided, the wheel track is widened, the structure height is reduced, and the stability is improved.

Description

Technical Field

[0001] The invention belongs to mechanical parking equipment, and in particular to a vehicle transport device of the parking equipment. Background Art

[0002] Patent number CN0125858.1 introduces a vehicle transporter for comb-tooth exchange parking equipment. The structure of the transporter includes a long bottom frame with running wheels at the front and rear four corners and a lifting frame with cantilevered comb teeth on both sides. The gear on the long bottom frame drives the rack on the lifting frame to make the lifting frame move up and down. The balance between the lifting frame and the long bottom frame is maintained by the guide pillars and guide sleeves set near the four corners.

[0003] Over the years, various comb carrier products based on this patented technology have been found to have the following important defects in actual operation:

[0004] 1. In order to cope with the inner wheel spacing of various commonly used vehicle models, the frame width of the lifting frame can only be limited to about 1 meter wide. In order to make full use of the clearance height of the parking facility, it is necessary to reduce the height of the fixed comb frame as much as possible, which requires the lower limit position of the lifting frame to be as close to the ground as possible. Therefore, the lifting frame can only be designed to have an inner width greater than the outer width of the long bottom frame, so that the lifting frame lowered to the lower limit position is sleeved on the periphery of the long bottom frame. In order to ensure the safety strength of the comb teeth that bear the weight of the vehicle, the cross-sectional width of the lifting frame needs to be wide enough, which results in the left and right side beams of the long bottom frame located in the hollow space of the lifting frame being only about 0.8 meters wide, and the wheelbase of the running wheels installed in the side beams of the long bottom frame being only about 0.78 meters. When carrying a heavy vehicle body with a width of 1.8 meters and moving horizontally, it is difficult to balance the stability, moving speed and acceleration of the transporter, and it is difficult to ensure that the transporter avoids instability and shaking during efficient operation. In order to obtain the widest possible wheelbase of the running wheel, the width of the side beam of the lifting frame can only be narrowed. From the actual product, the width of the lifting frame side beam with comb teeth welded is only 5 cm. This width affects the carrying capacity of the comb teeth, not only reducing the overall carrying capacity of the transporter, but also easily causing the comb teeth to deform excessively under heavy pressure conditions, resulting in tooth collision failure.

[0005] 2. Since the long bottom frame and the lifting frame are usually welded by profiles, the guide posts and guide sleeves are respectively fixed on the non-processed surfaces of the long bottom frame and the lifting frame by welding or bolt connection, so that the above structure has the following common problems: too high installation accuracy requirements, complex installation, and difficult debugging; the more pairs of guide posts and guide sleeves are used, the greater the difficulty of installation and debugging. It is a big problem in the existing mechanical processing, welding, and assembly processes to ensure that each pair of guide posts and guide sleeves maintain sliding fit to obtain higher positioning accuracy, and each pair of guide posts and guide sleeves runs smoothly. Although the method of paired machining can solve the positioning accuracy problem, the processing cost is high and the production efficiency is low. Moreover, under long-term heavy load conditions, the long bottom frame and the lifting frame will inevitably produce undesirable deformation, and the welding stress of the key points will gradually release. In the lightest case, the guide posts and guide sleeves will be stuck in operation, and in the worst case, the lifting frame will not be able to achieve the lifting action and cannot work, and even the welding of the guide posts, guide sleeves and the long bottom frame or lifting frame will be open, and the connecting bolts will be broken, resulting in a high failure rate during use and high maintenance costs.

[0006] 3. The guide post and guide sleeve mechanism provide balance for the lifting frame, and sufficient height space needs to be provided for the guide post and guide sleeve. This allows the overall height of the transporter to remain high after the lifting frame is lowered to the lower limit position. In specific implementation, the space between the running wheels is generally sought downward, which results in the need to reserve a depth of about five centimeters between the ground tracks of the parking space of the parking facility, or to set the track height to more than five centimeters. This increases the overall investment of the project, reduces the headroom utilization efficiency of the parking building space, and relatively reduces the height of the preset vehicle model.

[0007] 4. The rack and pinion lifting mechanism has the following defects: First, the entire load of the transporter is borne by only a few tooth pairs, which can easily cause wear and deformation and malfunction; second, the rack and pinion has no limit self-locking function. After reaching the limited height, it can only rely on sensors, travel switches, and motor brake self-locking mechanisms to ensure the accuracy of the lifting height and self-locking positioning. The reliability is not easy to guarantee, and the motor control system has high requirements. It is easy to have inaccurate height positioning, resulting in gear collision accidents; third, the rack and pinion transmission cannot provide smooth starting and braking effects for the lifting process, and can only rely on motor frequency conversion control or servo motor to provide a smooth stroke.

[0008] 5. In order to reduce the overall height of the carrier and make full use of the lifting height that the guide column and guide sleeve can provide, existing products generally use two comb teeth with an ultra-wide spacing of more than 25 cm for positioning wheels. This width of the tooth gap is not only harmful to the wheel body with a smaller diameter, but also makes it easier for the chassis of the low-chassis vehicle to collide with the carrier when a pair of wheels sink too much. Reducing the tooth gap of the positioning comb teeth will affect the vehicle positioning effect and cause the vehicle to become inertially unstable and dislocated. If three comb teeth are used to form a concave layout with higher sides and lower middle, although a much better wheel positioning posture can be obtained, the lower comb teeth will increase the preset lifting height of the lifting frame, thereby increasing the overall height of the carrier.

[0009] 6. Since a gear rack mechanism and a guide column and guide sleeve mechanism are arranged between each pair of travel wheels, there is no space for installing a common shaft between each pair of travel wheels, resulting in the use of two diagonally arranged drive motors to drive one travel wheel respectively. This not only increases the number of motors, but also requires the system to achieve precise synchronization of the two travel drive motors, increasing the difficulty of control. Summary of the invention

[0010] In order to solve the above defects of the prior art, the present invention proposes the following technical solutions:

[0011] This is a vehicle carrier for comb-tooth exchange parking equipment, characterized in that:

[0012] The main frame includes long longitudinal beams arranged on the left and right sides, and the outer side of each long longitudinal beam is provided with comb teeth extending outward laterally; the long longitudinal beams on both sides are connected by a main cross beam;

[0013] There are scissor lift devices at the front and rear of the main frame.

[0014] The scissor lift device comprises a first scissor rod and a second scissor rod arranged on the left and right sides, and the middle part of the first scissor rod on each side is hinged with the middle part of the second scissor rod to form a scissor mechanism;

[0015] The scissor lift device includes a scissor rod base frame;

[0016] The first end of the first scissor rod on each side is hinged to the long longitudinal beam, and the second end is slidably connected to the scissor rod base frame;

[0017] The first end of the second scissor rod on each side is hinged to the scissor rod base frame, and the second end is slidably connected to the long longitudinal beam;

[0018] The scissor lift device includes a lift drive mechanism, which drives the angle between the first scissor rod and the second scissor rod to change in a predetermined manner, thereby driving the long longitudinal beam to rise and fall within a preset range;

[0019] Travel wheels and guide wheels are installed on both sides of the scissor rod base frame.

[0020] Compared with the prior art, the present invention eliminates the long bottom frame component and replaces the lifting frame and the long bottom frame of the prior art with a single main frame, thereby avoiding the spatial size contradiction between the lifting frame and the long bottom frame in the prior art, allowing the main frame to form an ideal cross-sectional shape, not only providing a much stronger base support for the comb teeth, improving the carrying capacity of the carrier, but also providing ideal conditions for compressing the overall height of the carrier as much as possible. In addition, the single main frame method can widen the wheelbase of the walking wheel as much as possible, improving the stability of the carrier when walking.

[0021] The present invention replaces the vertical guide mechanism of the guide column and guide sleeve and the gear rack lifting mechanism with a scissor lift device, which not only eliminates the aforementioned defects caused by the guide column and guide sleeve mechanism in the prior art, but also avoids the aforementioned defects of the gear rack mechanism.

[0022] Preferably,

[0023] The scissor lift device comprises a lift drive shaft driven by a motor and installed on the first scissor rods on the left and right sides.

[0024] The driving mechanism includes a short rocker and a long rocker located on the left and right sides of the scissors-type jacking device, one end of the short rocker is fixedly connected to the jacking drive shaft, the other end of the short rocker is hinged to the lower end of the long rocker located above, and the upper end of the long rocker is hinged to the first scissors-type rod.

[0025] or,

[0026] The scissor lift device comprises a lift drive shaft driven by a motor and installed on the second scissor rods on the left and right sides.

[0028] The lifting mechanism adopts a combination of long and short rockers to achieve reliable and smooth speed change effects at the starting point and end point of the lifting stroke. Moreover, it does not need to rely on high-precision sensors and other locking mechanisms to achieve repeatable high-precision positioning and reliable locking and braking effects at the upper and lower limit positions of the lifting stroke.

[0029] Preferably,

[0030] A travel drive shaft driven by a motor is provided between the left and right sides of the scissor rod base frame;

[0031] The travel wheels are mounted at both ends of the travel drive shaft;

[0032] One end of the second scissor rod is hinged to the travel drive shaft.

[0033] The above additional preferred features enable the carrier to maintain a relatively low overall height while the lifting mechanism can easily provide a lifting range of more than 18 cm, so that the overall height of the comb tooth component can be increased to allow a three-comb structure with a concave layout to be set.

[0034] Preferably,

[0036] The first end of the first scissor rod is hinged to the scissor rod top frame;

[0039] Preferably,

[0040] The driving motors of the lifting driving shaft and the traveling driving shaft are installed on the second scissor rod.

[0093] The operating principle of a design scheme of a scissor lift device 2 applied to an embodiment of the carrier proposed by the present invention is as follows: Figures 1 to 3 shown.

[0094] See also Figure 1 The scissor lift device 2 includes a first scissor rod 21, a second scissor rod 22, a scissor rod base frame 23, a scissor rod top frame 24, a short rocker 25 and a long rocker 26.

[0095] Among them, the front hinge hole 211 of the first scissors rod is hinged to the front hinge hole 2421 of the top frame side beam at the front end of the top frame side beam 242 of the scissors rod top frame 24 by means of an axis; the middle hinge hole 212 of the first scissors rod is hinged to the middle hinge hole 222 of the second scissors rod by means of an axis; the rear hinge hole 213 of the first scissors rod is slidably connected to the rear slide groove 2322 of the bottom frame side beam of the scissors rod bottom frame 23 by means of other sliding parts such as rollers or sliders.

[0096] The front hinge hole 221 of the second scissors rod is hinged to the front hinge hole 2321 of the base frame side beam at the front end of the base frame side beam 232 of the scissors rod base frame 23; the rear hinge hole 223 of the second scissors rod is slidably connected to the rear slide groove 2422 of the top frame side beam of the scissors rod top frame 24 by means of other sliding parts such as rollers or sliders.

[0097] The long rocker root hinge hole 261 is hinged to the first scissor rod drive hinge hole 214 by means of a shaft, and the long rocker dynamic hinge hole 262 is hinged to the short rocker dynamic hinge hole 252 by means of a shaft; the short rocker root hinge hole 251 is hinged to the second scissor rod drive hinge hole 224 by means of a jacking drive shaft 27.

[0098] The two ends of the travel drive shaft 28 are provided with the carrier travel wheels 3 .

[0099] When the lifting drive shaft 27 is driven by the motor to rotate 180° counterclockwise, the short rocker 25 will press the scissor rod top frame 24 fixedly connected to one end of the main frame of the carrier to rotate. Figures 1 to 3 The order is from the lowest position to the highest position.

[0100] from Figure 1 and Figure 3 It can be seen that when the short rocker 25 rotates to 270° and the upper and lower limit positions of 90°, the height position of the scissor rod top frame 24 will be rigidly locked. From the principle of the rocker mechanism, it can be seen that even if the positioning angle of the short rocker 25 at the upper and lower limit positions has a small deviation, it will also maintain a high locking force and positioning accuracy. In addition, due to the principle of the rocker mechanism, the lifting process of the scissor rod top frame 24 has a gentle acceleration and deceleration effect.

[0123] Fig.26 , Fig. 27The display carrier uses the running wheels and the guide wheels to enter the parking space under the guidance of the carrier guide rail 7 at a parking space, aligns and stops below the parking space front comb teeth 61 and the parking space rear comb teeth 62, and allows the carrier's front comb teeth 131 and rear comb teeth 132 to rise and fall in the parking space comb teeth gaps.

[0124] from Fig.28 and Fig.29 It can be seen that the left and right two of the three front comb teeth 131 of the carrier are arranged inwardly in the shape of a wheel with a diameter of 60 cm, and the middle front comb tooth 131 is at a lower position. This arrangement shape can obviously provide a more stable and reliable wheel lifting and positioning effect without excessively squeezing the tire than the prior art with only two comb teeth. However, this will cause the comb teeth to occupy a space height in the horizontal projection direction that is about 2 cm higher than the height of a single comb tooth. In other words, the height space between the bottom surface of the comb teeth at the lowest position and the top edge of the comb teeth at the highest position reaches about 8 cm. In order to ensure that there is no tooth collision accident during the operation of the carrier, the lifting range of the comb teeth of the carrier should not be less than 18 cm. In the prior art, the lifting stroke according to the gear rack method is generally not easy to reach this height. Or, even if this height is reached, the overall height of the carrier will be increased. However, the lifting method of the long and short rocker + scissor rod proposed by the present invention can easily reach a lifting range of more than 18 cm and will not increase the total height of the carrier.

[0125] from Fig.30 and Fig.31 It can be seen that when the comb teeth of the carrier of the present invention are at the highest position and the lowest position, a safety gap of about 2 cm can be maintained between the comb teeth of the parking space.

[0126] Although the long and short rocker arm lifting scheme described in the present invention has good application effects, it is obvious that the long and short rocker arm lifting mechanism proposed in the present invention in conjunction with the scissors rod mechanism can be simply replaced by existing technologies such as a screw lifting mechanism, a hydraulic jacking rod mechanism, various cam mechanisms, and a gear rack mechanism, and achieve similar effects.

[0127] from Fig.28 It can be seen that the scissor-type lever mechanism proposed in the present invention provides a scissor-type lever base frame 23 that always maintains a horizontal suspended state as a stable installation base for the guide wheel 4.

[0128] from Fig.29 , Fig.31 , Fig.31 It can be seen that the drag chain mounting frame 9 arranged on the side of a scissor lift device 2 can be used to install a drag chain for arranging the power supply cable of the carrier.

[0129] The travel drive shaft 28 of the present invention is directly and rigidly connected to the carrier travel wheels 3 at both ends of the shaft through keyways. After the motor drives one travel drive shaft 28 to rotate, the two travel wheels 3 at the ends of the shaft can be operated synchronously. The front and rear scissor lift devices 2 of the carrier of the present invention can both be provided with travel drive shafts 28. Therefore, in actual application, if the load allows, only one of the travel drive shafts 28 can be equipped with a drive motor. In this case, compared with the prior art, one travel drive motor can be reduced.
