Description

Technical Field

[0001] This invention relates to the field of garage traction devices, and in particular to a vertical lifting garage traction hook. Background Technology

[0002] Vertical lift parking garages are mostly two-tiered structures. Each parking space has a platform for carrying vehicles. The upper platform only moves vertically, while the ground-level platform only moves laterally. One empty space on the ground level can be moved left or right as the platform moves laterally, causing the corresponding upper platform to descend to the ground, allowing vehicles to enter or exit the parking space. For the lower platform, vehicles can directly enter or exit the parking space. The main method of transporting vehicles to their destination is through the lifting or lateral movement of the platform.

[0003] Existing towing hooks used for lifting and lowering vehicle platforms result in concentrated stress on the lifting section of the platform where the hook connects. During long-term lifting and lowering, uneven stress on this section can lead to loss of structural prestress. Furthermore, to facilitate disassembly of the hook and lifting section, a gap is typically left during connection. Over time, this gap can cause the towing hook and connection to sway, affecting the stability of the platform. When the platform descends to the ground, a rigid collision can easily occur between the hook and the lifting section, reducing their structural strength. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a traction hook for a vertical lift-type garage.

[0005] To achieve the above objectives, this application provides the following technical solution: a vertical lifting garage traction hook, comprising a car carrier plate installed in the garage, a pair of barrier beams fixed on the surface of the car carrier plate, and lifting assemblies detachably connected to both the front and rear ends of the barrier beams, with a hook assembly adapted to the lifting assembly above the lifting assembly, and a traction chain movably installed on the hook assembly.

[0006] The hoisting assembly includes a support base, an extension piece is fixedly connected to the bottom of the support base, and a through hole adapted to the support base is opened on the surface of the barrier beam. When the hoisting assembly and the hook assembly are installed together, the support base passes through the through hole and extends above the barrier beam.

[0007] A further improvement of the technical solution of the present invention is that the hoisting assembly further includes a collar, the surface of the support base is provided with a channel, the collar is symmetrically arranged on the inner side of the channel, and the inner side of the collar is rotatably connected with a swing bar.

[0008] The swing bars are arranged in a square shape. In their natural state, the ends of a pair of collars abut against the inner wall of the channel, and the tops of a pair of swing bars face each other, forming a triangular structure.

[0009] A further improvement of the technical solution of the present invention is that each of the swing bars is fitted with a limiting pin, and when the hoisting assembly and the hook assembly are installed together, the hook assembly passes through a pair of limiting pins.

[0010] A further improvement of the technical solution of the present invention is that the hook assembly includes a connecting part that can be fixed to the chain, a positioning seat is fixed on the inner side of the connecting part, and an extension shaft passes through the positioning seat.

[0011] The bottom of the extension shaft is fixedly connected to a balance hook, which includes a flat part. The two ends of the flat part extend in an inclined convex shape. When the hook assembly passes through a pair of limiting pins, the limiting pins are symmetrically distributed on the balance hook.

[0012] A further improvement of the technical solution of the present invention is that the hook assembly further includes a compression spring, and a pad is fixed to the bottom of the compression spring.

[0013] The bottom of the compression spring is fixed with a pad, which is fixed below the balance hook. When the balance hook is pressed down, the balance hook slides close to the pad, and the compression spring contracts under the pressure of the balance hook.

[0014] A further improvement of the technical solution of the present invention is that a central plate is fixed inside the channel opened on the surface of the support base, and round rods are fixed on both sides of the central plate, with sliding sleeves installed at the ends of the round rods.

[0015] The sliding sleeves located on both sides of the central plate are fixed to the surface of the collar. Pushing the bottom of the swing bar, the collar and sliding sleeves approach the central plate, and the end of the swing bar rises until a pair of limit pins disengage from the balance hook.

[0016] A further improvement of the technical solution of the present invention is that an extension washer is fixed to one end of the round rod located inside the sliding sleeve, a compression spring II is fixed to the surface of the extension washer, and the other end of the compression spring II is fixed to the inner wall of the sliding sleeve.

[0017] The surface of the sliding sleeve has a groove that matches the extension pad. When the collar and the sliding sleeve are close to the central plate, the compression spring II contracts under the compression of the sliding sleeve.

[0018] In summary, the technical effects and advantages of this invention are as follows:

[0019] This invention improves the balance of the barrier beam and vehicle platform during lifting and lowering, dispersing concentrated tension and ensuring uniform stress on the entire lifting assembly. It effectively avoids the swaying phenomenon that occurs during traditional hook-traction lifting, ensuring the stability of the lifting assembly, barrier beam, and vehicle platform during the lifting process. Simultaneously, it provides a buffering effect between the lifting assembly and hook assembly as they descend to the ground, further reducing rigid friction between them. This provides protection for both. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Reference Figure 1-4 The illustrated vertical lift parking garage traction hook includes a vehicle carrier platform 1 installed inside the garage. A pair of barrier beams 2 are fixed to the surface of the vehicle carrier platform 1. Lifting assemblies 3 are detachably connected to both the front and rear ends of the barrier beams 2. Hook assemblies 4, adapted to the lifting assemblies 3, are mounted above the lifting assemblies 3, and a traction chain is movably mounted on the hook assemblies 4. During the use of the automated parking garage, after a vehicle enters the vehicle carrier platform 1, the barrier beams 2 effectively prevent lateral displacement of the vehicle, thus limiting its movement. There are four lifting assemblies 3 and four hook assemblies 4, distributed at the four corners above the vehicle carrier platform 1.

[0032] The servo motor can control the chain rotation. A hook assembly 4 is fixed below the chain. By connecting the hook assembly 4 at the four corners to the lifting assembly 3, the hook assembly 4 can lift the barrier beam 2 and the vehicle platform 1 to drive the vehicle platform 1 to rise.

[0033] The hoisting assembly 3 includes a support base 31, with an extension piece 32 fixedly connected to the bottom of the support base 31. A through hole 5, matching the support base 31, is provided on the surface of the barrier beam 2. When the hoisting assembly 3 and the hook assembly 4 are installed together, the support base 31 passes through the through hole 5 and extends above the barrier beam 2. By sequentially passing fastening bolts through the support base 31, the barrier beam 2, and the extension piece 32, the support base 31 and the extension piece 32 within the hoisting assembly 3 can be fixed to the surface of the barrier beam 2, thus completing the installation of the hoisting assembly 3 and the barrier beam 2.

[0034] By adopting a bent structure for the extension piece 32, the connection strength between the lifting assembly 3 and the barrier beam 2 can be improved. During the lifting and lowering process of the lifting assembly 3 through the hook assembly 4, the phenomenon of bolt loosening, which would cause gaps between the lifting assembly 3 and the barrier beam 2, can be effectively avoided. This improves the tightness of the connection between the lifting assembly 3 and the barrier beam 2 during the lifting and lowering process, effectively ensuring the balance of the barrier beam 2 and the vehicle platform 1 during the lifting and lowering process, and improving the safety performance of the hook structure.

[0035] like Figure 4 , Figure 5 As shown, the hoisting assembly 3 also includes a collar 33. The surface of the support base 31 has a channel, and the collar 33 is symmetrically arranged inside the channel. The inner side of each collar 33 is rotatably connected to a swing bar 34.

[0036] The swing bars 34 are arranged in a U-shape. In their natural state, the ends of a pair of collars 33 abut against the inner wall of the channel, and the tops of the pair of swing bars 34 face each other, forming a triangular structure. During the lifting and lowering movement of the hook assembly 4 and the hoisting assembly 3, because the pair of swing bars 34 extend above the support base 31, and the three form a triangular force-bearing structure, the pair of swing bars 34 can make the tension on the support base 31 more uniform and disperse the concentrated tension during the lifting and raising of the hoisting assembly 3 by the hook assembly 4, so that multiple hoisting assemblies 3 can be lifted smoothly. This effectively improves the stability of the hoisting assembly 3 during the lifting and lowering process.

[0037] like Figure 5 As shown, each swing bar 34 has a limiting pin 35 fitted at its top. When the lifting assembly 3 and the hook assembly 4 are installed together, the pair of swing bars 34 and the support base 31 form a triangular force-bearing structure, with the ends of the swing bars 34 close together, and further, the limiting pins 35 close together. The hook assembly 4 passes through the pair of limiting pins 35. The limiting pins 35 and the hook assembly 4 are detachable, so that the lifting assembly 3 and the hook assembly 4 can be disassembled for maintenance.

[0038] Example 2: As Figure 5 , Figure 6 As shown, the hook assembly 4 includes a connecting part 41 that can be fixed to the chain, a positioning seat 42 is fixed on the inner side of the connecting part 41, an extension shaft 43 passes through the positioning seat 42, and the extension shaft 43 can rotate on the positioning seat 42.

[0039] A balance hook 44 is fixedly connected to the bottom of the extension shaft 43. The balance hook 44 includes a flat part with inclined protrusions at both ends. When the hook assembly 4 passes through a pair of limit pins 35, the limit pins 35 are symmetrically distributed on the balance hook 44. The pair of limit pins 35 are located on the left and right sides of the extension shaft 43, respectively. When the hook assembly 4 is connected to the lifting assembly 3 for lifting, the balance hook 44, as a connecting component, effectively avoids the swaying phenomenon in the traditional hook traction lifting process by adopting a symmetrical structure and connecting it with a pair of limit pins 35, thus ensuring the stability of the lifting assembly 3, the barrier beam 2, and the vehicle platform 1 during the lifting process.

[0040] like Figure 7 , Figure 8 As shown, the hook assembly 4 also includes a compression spring 45, and a pad 46 is fixed to the bottom of the compression spring 45.

[0041] A pad 46 is fixed to the bottom of the compression spring 45 and is fixed below the balance hook 44. When the balance hook 44 is pressed down, the balance hook 44 slides close to the pad 46, and the compression spring 45 contracts under the compression of the balance hook 44. When the vehicle platform 1 is lowered to the ground, a rigid collision is likely to occur between the hoisting assembly 3 and the hook assembly 4.

[0042] At this time, the compression spring 45 deforms under the pressure of the limiting pin 35 and the balance hook 44, which buffers the lifting assembly 3 and the hook assembly 4, effectively preventing the collision between the balance hook 44 and the limiting pin 35, and further reducing the rigid friction between the hook assembly 4 and the lifting assembly 3. It protects both of them.

[0043] like Figure 5 , Figure 6 As shown, a central plate 6 is fixed inside the channel opened on the surface of the support base 31, and round rods 7 are fixed on both sides of the central plate 6. A sliding sleeve 8 is installed at the end of the round rod 7.

[0044] The sliding sleeves 8 located on both sides of the central plate 6 are fixed to the surface of the collar 33. Pushing the bottom of the swing bar 34, the collar 33 and sliding sleeves 8 approach the central plate 6, the end of the swing bar 34 rises, and the position of the limiting pin 35 rises. At this time, the limiting pin 35 presses against the pad 46, the compression spring 45 is compressed and contracted, the distance between the balance hook 44 and the pad 46 shortens, and then the limiting pin 35 is pulled outward until the limiting pin 35 disengages from the balance hook 44, thus completing the disassembly and separation between the lifting assembly 3 and the hook assembly 4.

[0045] like Figure 5 , Figure 6 As shown, an extension washer 9 is fixed to one end of the round rod 7 located inside the sliding sleeve 8. A compression spring 10 is fixed to the surface of the extension washer 9, and the other end of the compression spring 10 is fixed to the inner wall of the sliding sleeve 8.

[0046] The surface of the sliding sleeve 8 has a groove that matches the extension pad 9. When the collar 33 and the sliding sleeve 8 approach the central plate 6, the compression spring 10 contracts under the compression of the sliding sleeve 8. The purpose of providing the compression spring 10 is to drive the collar 33 to abut tightly against the inner wall of the channel opened in the support base 31 during the lifting and lowering process of the hoisting assembly 3, and to drive the tops of the pair of swing bars 34 to move closer, so as to ensure that the hoisting assembly 3 and the hook assembly 4 are always in a tight connection state during the lifting and lowering process.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
