Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional parking devices, and more specifically, to a basic comb-tooth limiting device for a mechanical three-dimensional parking garage. Background Art

[0002] The comb-tooth type is a form of transportation for stereo garage products. The structure is divided into a lifting channel and a berth. The lifting channel is equipped with a lifting comb frame and a lifting system. The lifting comb is divided into two parts: the front wheel comb and the rear wheel comb. The berth is a transverse comb frame distributed on both sides of the lifting channel. The entrance and exit are set in the lifting channel on the ground floor, or a fixed turntable is provided. When parking a car, the lifting comb frame is exchanged with the transverse comb frame to reach the designated layer, and the transverse comb frame is used to move horizontally to realize the transportation from the channel to the berth. The transverse turntable is used to realize the vehicle turning around and entering and exiting the warehouse.

[0003] Existing mechanical multi-story parking garages generally store and retrieve vehicles in the following or opposite method: first, the vehicle is parked in the access room, then the vehicle is moved to the lifting or transverse movement device by a carrier, and then the lifting or transverse movement device transports the vehicle to the parking layer where the target parking space is located, and finally the vehicle is parked in the parking space by the carrier.

[0004] When customers park their cars, if the car is not parked in the center of the comb platform, but is biased or tilted to the left or right, it will cause difficulties for the lifting system to complete its task, and may even cause an accident in serious cases.

[0005] Customers can only adjust the position of the car by observing the position of the car with their eyes, which requires a high level of reverse parking skills, and the customer's satisfaction with the use of the three-dimensional parking garage is affected. Possible dangerous situations include: 1. The lifting system starts working before the front wheels of the vehicle reach the front wheel comb position of the lifting comb; 2. The lifting system starts working when the front wheels of the vehicle only reach a part of the front wheel comb or only one front wheel reaches the front wheel comb; 3. The vehicle stops on the upper side of the lifting comb or stops diagonally. If the parking staff does not notice the above situation and the lifting system starts working, it may cause damage to the vehicle or personnel.

[0006] Therefore how to park the car on the comb rack quickly and accurately, improve the structure of mechanical three-dimensional parking garage, and better adapt to market demand, has huge practical significance. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a basic comb tooth limit device for a mechanical multi-story parking garage in response to the above-mentioned shortcomings. This limit device cooperates with the comb tooth structure of the original multi-story parking garage. According to actual parking and parking needs, limit comb teeth are added to the basic comb tooth limit device, which can accurately and quickly allow the driver to find the exact position where the wheels need to be parked. In order to ensure that the vehicle is parked in a safe position on the lifting comb tooth frame, an automatic detection protection is added to see whether the vehicle position meets the requirements, thereby improving the safety and efficiency of storing and retrieving vehicles, and adding a safety protection system for unmanned intelligent mechanical parking equipment.

[0008] The purpose of the present invention is achieved through the following technical solutions:

[0009] Provided is a mechanical three-dimensional parking garage basic comb limit device, comprising symmetrically arranged front wheel basic comb teeth and rear wheel basic comb teeth, wherein the front wheel basic comb teeth and the rear wheel basic comb teeth each comprise a plurality of comb tooth structures, wherein the comb tooth structure comprises a bottom plate, wherein at least two column structures are longitudinally mounted on the bottom plate, and a crossbeam structure is connected to the top end of the column structure, so that the comb tooth structure is a hollow rectangular structure;

[0010] A limited position comb tooth is arranged between the comb tooth structures of the front wheel basic comb teeth, and a front wheel positioning device is arranged on the limited position comb tooth; the front wheel positioning device comprises a front wheel positioning support plate and a flap movably connected to the edge of the front wheel positioning support plate;

[0011] An adjustment structure is installed downwardly from the upper surface of the front wheel in place support plate and penetrates through the interior of the front wheel in place support plate, and the adjustment structure includes a pressure rod structure, a compression spring and a spring pad; a bearing structure is installed at the top of the pressure rod structure; a compression spring is provided on the outer wall of the pressure rod structure, one end of the compression spring abuts against the bearing structure, and the other end abuts against the spring pad;

[0012] The adjusting structure is provided with a guide sleeve outside, the inner wall of the guide sleeve is provided with a stop step, and the stop step is provided with a spring pad sleeved on the outer wall of the pressure rod structure;

[0013] A travel switch pressure plate is fixed to the end of the pressure rod structure; one end of the travel switch pressure plate extends to one side of the limit switch to control the opening and closing of the switch.

[0014] Furthermore, the front wheel in place support plate is a block structure, the upper surface forms an angle of 5° to 30° with the horizontal plane, and the lower surface is parallel to the bottom plate.

[0015] Furthermore, the flap is installed on the edge of the highest side of the front wheel in place support plate through a rotating shaft, and a positioning block is provided on the inner surface of the flap, and the positioning block is adapted to the groove structure provided on the front wheel in place support plate.

[0016] Furthermore, the bearing structure is a deep groove ball bearing, and the bearing structure is installed through a shaft rod at the top end of the pressure rod structure, and the deep groove ball bearing is sleeved on the shaft rod.

[0017] Furthermore, the outer wall of the guide sleeve is provided with a connecting ear, and the guide sleeve is fixedly connected to the mounting plate through the connecting ear, and the mounting plate is arranged parallel to the lower surface of the front wheel positioning device.

[0018] Furthermore, the crossbeam structure is a rectangular structure, and the plurality of comb tooth structures form comb tooth planes with the same intervals.

[0019] Furthermore, the crossbeam of the comb tooth structure on the adjacent side of the limiting comb tooth is an inclined surface structure, forming a V-shaped positioning groove structure with the front wheel positioning device of the limiting comb tooth.

[0020] Furthermore, rib plates are provided between adjacent comb tooth structures of the rear wheel basic comb teeth.

[0021] The mechanical stereo parking garage basic comb limit device of the present invention is installed in the lifting comb pit of the garage entrance and exit. When the front wheel of the car presses the flap of the front wheel in place device, the flap rotates downward through the movable connection structure (such as a hinge) to fit the slope surface of the front wheel in place support plate, and at the same time forces the pressure rod structure to move downward through the guide sleeve. The pressure rod structure is equipped with a travel switch pressure plate, and the travel switch pressure plate contacts the limit switch contact.

[0024] When the vehicle is parked, the lifting comb frame is lowered and passes through the front and rear basic comb frames. The front and rear basic comb frames and the lifting comb frame are at the same height. When the vehicle enters the lifting channel, only when the front wheels on both sides press the flap can the two safety protection switches be triggered. These two safety protection switches are connected in series in the safety circuit of the PLC control system of the mechanical parking equipment, indicating that the front and rear and left and right positions of the vehicle meet the parking requirements before the lifting comb can be lifted. This avoids the dangerous situation that the front wheels are not parked in place, or the vehicle (a vehicle with a narrow wheelbase) is parked sideways and only presses the lifting comb on one side.

[0025] The basic comb limit device of the mechanical three-dimensional parking garage of the present invention not only improves the comfort of drivers entering and exiting the garage and facilitates parking and retrieval of vehicles, but also limits the position of the vehicle on the lifting comb teeth, adds an automatic vehicle position protection device, prevents vehicle damage caused by the vehicle not being parked in place or parking sideways, and improves the safety and efficiency of parking and retrieval of vehicles.

[0035] like Figure 1 to Figure 6 As shown, the basic comb teeth limiting device of the mechanical stereoscopic parking garage includes a front wheel basic comb teeth 1 and a rear wheel basic comb teeth 2 symmetrically arranged on both sides of a lifting comb teeth frame 3. The front wheel basic comb teeth 1 and the rear wheel basic comb teeth 2 both include a plurality of comb tooth structures.

In the present embodiment, the column structures 14 are arranged in two, which are respectively arranged on both sides of the bottom plate 11; and the top end of the column structure 11 is connected to a crossbeam structure 15, so that the comb tooth structure and the bottom plate 11 form a rectangular hollow structure; the crossbeam structure 15 is a rectangular structure, and the plurality of comb tooth structures form planes with the same spacing.

[0036] The basic comb tooth limiting device of the mechanical stereoscopic parking garage is used in conjunction with an existing lifting comb tooth frame, and the gaps in the comb tooth structure can accommodate the comb teeth of the lifting comb tooth frame 3.

[0037] A limited comb tooth is arranged between the comb tooth structures of the front wheel basic comb teeth 1, and a front wheel positioning device is arranged on the limited comb tooth; the front wheel positioning device comprises a front wheel positioning support plate 124 and a flap 121 movably connected to the edge of the front wheel positioning support plate 124; the front wheel positioning support plate 124 is a block structure, and its upper surface is inclined at an angle of 5° to 30° with the horizontal plane, and the front wheel positioning support plate 124 is arranged parallel to the bottom plate 11 on the lower surface. More specifically, the flap 121 is installed on the edge of the highest end of the front wheel positioning support plate 124 through a rotating shaft 123, and a positioning block 122 is arranged on the inner surface of the flap 121, and the positioning block 122 is adapted to the groove structure on the front wheel positioning support plate 124.

[0038] The basic comb teeth limiting device of the mechanical three-dimensional parking garage of this embodiment is provided with limiting comb teeth on the basic comb teeth 1 of the front wheel. When the vehicle is parked, the lifting comb teeth frame 3 is lowered and passes through the front and rear basic comb teeth frames. The front and rear basic comb teeth frames and the lifting comb teeth frame are at the same height. When the vehicle enters the lifting channel, only when the front wheels on both sides press the flap, can the two safety protection switches be triggered. The two safety protection switches are connected in series in the safety circuit of the PLC control system of the mechanical parking equipment, indicating that the front and rear and left and right positions of the vehicle meet the parking requirements, and the lifting comb teeth can be lifted. It avoids the dangerous situation that the front wheel is not parked in place, or the vehicle (a vehicle with a narrow wheelbase) is parked sideways, and only one side of the lifting comb teeth is pressed.

[0039] In addition, an adjustment structure is installed downwardly extending from the upper surface of the front wheel support plate 124 and penetrating through the interior of the front wheel support plate 124, and the column height 14 is greater than the height of the adjustment structure; the adjustment structure includes a pressure rod structure 18, a compression spring 191 and a spring pad 192; a bearing structure 17 is installed on the top of the pressure rod structure 18, and a compression spring 191 is provided on the outer wall of the pressure rod structure 18, one end of the compression spring 191 abuts against the bearing structure 17, and the other end abuts against the spring pad 192; a guide sleeve 19 is provided on the outside of the adjustment structure, and a stop step is provided on the inner wall of the guide sleeve 19, and a spring pad 192 is provided on the outer wall of the pressure rod structure 18.

[0042] As a preferred solution of this embodiment, the bearing structure 17 is a deep groove ball bearing, and the bearing structure 17 is sleeved on a shaft (not shown) installed at the top end of the pressure rod structure 18.

[0043] The mechanical stereo parking garage basic comb limit device of the present invention is installed in the lifting comb pit of the garage entrance and exit. When the front wheel of the car presses the flap of the front wheel in place device, the flap rotates downward through the movable connection structure (such as a hinge) to fit the slope surface of the front wheel in place support plate, and at the same time forces the pressure rod structure to move downward through the guide sleeve. The pressure rod structure is equipped with a travel switch pressure plate, and the travel switch pressure plate contacts the limit switch contact. When the travel switch pressure plate moves downward, the limit switch action is triggered, thereby indicating that the front wheel has been in place. When the front wheel of the car leaves the flap, the compression spring is restored, the flap is lifted, and the pressure rod structure moves upward, thereby realizing the restoration of the limit switch contact, indicating that the front wheel has left.

[0044] As a preferred solution of this embodiment, the crossbeam of the comb structure on the adjacent side of the limiting comb is an inclined structure 16, which forms a V-shaped positioning groove structure with the front wheel positioning device of the limiting comb. The setting of this structure is conducive to positioning the front wheel between the front wheel basic comb teeth 1, and can accurately and quickly allow the driver to find the exact position where the wheel needs to be parked.

[0045] In order to enhance the strength of the rear wheel base comb teeth, rib plates 20 are provided between adjacent comb tooth structures.
