DETAILED DESCRIPTION

[0024] The following description is only for disclosing the utility model so that those skilled in the art can implement the utility model. The examples in the following description are only as examples, and those skilled in the art can think of other obvious modifications. The basic principles of the utility model defined in the following description can be applied to other implementation schemes, modification schemes, improvement schemes, equivalent schemes and other schemes without departing from the spirit and scope of the utility model.

[0025] Example 1:

[0026] A car changing and repairing hoist with the anti-falling function, as shown in the figure, Figure 1 , comprises a frame assembly 1, a lifting drive assembly 2 and a loading platform assembly 3.

[0027] As shown in the figure, Figure 1 , the frame assembly 1 is a frame composed of a plurality of vertical and horizontal rod bodies, used for supporting the lifting drive assembly 2 and the loading platform assembly 3.

[0028] The frame assembly 1 is provided with a support part, which is two groups of support rods 11 in front and back, and the support rod 11 is a horizontal pull rod for composing the frame assembly 1.

[0029] The frame assembly 1 is internally provided with a plurality of guide rails 12, and in the embodiment, four groups of guide rails 12 are provided, two groups in front and back, used for guiding the lifting of the loading platform assembly 3.

[0030] The frame assembly 1 is provided with a top buffer 14.

[0031] The frame assembly 1 is provided with a buffer support 13, and the loading platform frame 33 is provided with a bottom buffer 34 used for contacting the buffer support 13.

[0032] The top buffer 14 and the bottom buffer 34 respectively serve to buffer the loading platform when it reaches its upper and lower limit positions.

[0033] like Figure 1 , Figure 2 The loading platform assembly 3 is mounted on the frame assembly 1, and the lifting drive assembly 2 is used to drive the loading platform assembly 3 to lift and lower on the frame assembly 1. The loading platform assembly 3 includes a loading platform frame 33, a suspension track 31 mounted on the loading platform frame 33, and a fall protection positioning assembly 32.

[0034] The loading platform frame 33 can move up and down along the guide rail 12, and the loading platform frame 33 is provided with guide wheels 35 for contacting the guide rail 12.

[0035] The suspended vehicle track 31 is used to dock with the overhead suspended track / parking track 41.

[0036] Fall arrestor positioning assembly 32 includes a vertical plate 321, a positioning block 322, a limiting body 324, a positioning block rotation drive, and a hydraulic buffer 327, such as Figure 2 , Figure 3 Two sets of upright plates 321 are installed on the loading platform frame 33. Positioning blocks 322 are installed at the front and rear positions between the two sets of upright plates 321. The rotation drive of the positioning blocks includes a drive cylinder 325. The piston rod of the drive cylinder 325 is hinged to the hinge point 326 on the positioning block 322. The drive cylinder 325 is hinged to the upright plate 321. The extension and retraction of the piston rod controls the rotation of the positioning block 322.

[0037] Specifically, the positioning block 322 is installed between the two sets of upright plates 321 via the rotary shaft 323. The limiting body 324 is a shaft used to contact the tail of the positioning block 322 for limiting. The limiting body 324 is provided with a through hole for installing the hydraulic buffer 327.

[0038] Positioning block 322 has a positioning state and a retracted state, such as Figure 3 In the positioning state, the positioning block 322 can contact the support part to achieve the support effect of the loading platform component 3, thereby ensuring stability when getting on and off the vehicle. Since the anti-fall positioning component 32 has a simple structure, it can meet the stability requirements without the need for a complex loading platform structure, thus reducing the weight of the loading platform. The limiting body 324 is used to limit the positioning block 322 in the positioning state to prevent support failure. The hydraulic buffer 327 is used to buffer the positioning block 322, effectively reducing collisions, reducing noise, and improving the service life of the equipment.

[0039] In this embodiment, four sets of positioning blocks 322 are arranged symmetrically on both sides of the loading platform frame 33.

[0040] Preferably, the positioning block 322 is a wedge-shaped block, with the side that contacts the support being a flat surface and the top surface being an inclined surface.

[0041] When in use, the parking rack 4 is set on one side of the equipment, and the parking rack 4 has a parking rail 41.

[0042] The lifting path of the loading platform assembly 3 has three positions: high, medium, and low.

[0043] The high position is above the support rod 11. This position is used to switch the state of the positioning block 322. In the middle position, the suspension vehicle track 31 is connected to the overhead suspension track, and the positioning block 322 is in contact with the support rod 11 for the suspension vehicle to enter / exit. In the low position, it is in contact with the buffer bracket 13, and the suspension vehicle track 31 is connected to the parking track 41.

[0044] Work process: The suspended vehicle drives into the loading platform assembly 3 according to the instructions. The lifting drive assembly 2 lifts the loading platform assembly 3 to a high position. The four sets of positioning blocks 322 set on the top of the loading platform assembly 3 retract synchronously under the drive cylinder 325. Finally, the loading platform assembly 3 descends to a low position and aligns with the ground parking track 41. Then the suspended vehicle drives away from the vehicle replacement and maintenance lift.

[0045] After maintenance, the suspended vehicle enters the loading platform of the maintenance elevator via the ground-based vehicle-changing track (parking track 41). The loading platform is raised to the high position, and then the positioning block 322 extends, switching to the positioning state. The loading platform descends to the middle position, and the positioning block 322 rests on the support rod 11 set on the elevator frame, which serves to prevent settling and falling. At this time, the aluminum rail of the loading platform connects with the overhead track, and the suspended vehicle leaves the elevator.

[0046] In other words, the aluminum rails inside the loading platform rise and fall with the platform. At the low position, it connects with the ground-based vehicle-changing rails, allowing for vehicle changing. At the middle position, it connects with the overhead suspended rails, allowing the suspended vehicle to enter and exit the hoist. The high position is for extending or retracting the telescopic wedges.

[0047] This solution uses a positioning block 322 on the top of the loading platform, which enhances the stability and safety of the loading platform when loading and unloading, simplifies the structure of the loading platform, reduces its weight, and lowers the power of the lifting motor, thereby reducing equipment costs.

[0048] Example 2:

[0049] Based on Embodiment 1, this embodiment provides an implementation method for boosting the driving component 2, specifically, as follows: Figure 1The lifting driving assembly 2 comprises a lifting motor 21, a lifting chain 22 and a counterweight assembly 23, the lifting motor 21 drives the lifting chain 22 through a driving shaft and a driving sprocket, and the lifting chain 22 is connected with the counterweight assembly 23 and the cargo platform frame 33 through a plurality of reversing sprockets.

[0050] It will be understood by those skilled in the art that the embodiments of the present application described above and shown in the drawings are merely exemplary and do not limit the present application. The purpose of the present application has been fully and effectively achieved. The function and structural principle of the present application have been demonstrated and described in the embodiments, and the embodiments of the present application can be any deformation and modification without departing from the principle.
