Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting machine technology, and specifically relates to a lifting mechanism assembly with anti-wear tires. Background Technology
[0002] A car lift is a piece of equipment used in the automotive repair industry to lift vehicles. It plays a vital role in automotive repair and maintenance, essential for both major overhauls and minor repairs. While existing lifting assemblies can meet the basic needs of lifting vehicles, they typically lack vertical guide structures on the sides of the lifting mechanism. This makes the lifting structure susceptible to direct, non-vertical forces, leading to easy deformation and damage, and consequently significantly impacting the lifespan of the device.
[0003] For example, the utility model patent with announcement number CN219971704U discloses a medium-sized tire lifter. In the technical solution of this patent document, the support base and the threaded rod are used to make the pallet move vertically, thereby lifting the tire and the car. However, since there is no vertical guide structure on the side of the support base and the threaded rod, the threaded rod will directly bear non-vertical forces, making it easy to deform and be damaged. Therefore, it cannot fully meet people's needs. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tire-wear-resistant lifting mechanism assembly. This assembly not only meets the basic requirements for lifting vehicles but also features a vertical guide structure on the side of the lifting structure. This prevents the lifting structure from being easily damaged by non-vertical forces, thus better meeting people's usage needs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tire-wear-resistant lifting mechanism assembly, including a U-shaped base set on the ground, the opening of the base facing forward, and a first telescopic push rod vertically set at each of the four corners of the base. A receiving cavity is opened in the ground to accommodate the fixed end of the telescopic push rod. A U-shaped lifting frame with an open front end is set on the output shaft of the four first telescopic push rods. A climbing ramp with the top of the lifting frame is set at the front end of both ends of the base. A guide rod is vertically set at the bottom of the lifting frame and is vertically inserted and slidably connected to the base. The guide rod is located at the side end of the first telescopic push rod and in the receiving cavity. A guide hole is set on the base and is slidably connected to the guide hole. A tire-wear-resistant limiting module for limiting the tires of the car is also set on the lifting frame.
[0006] As a further improvement of this utility model, the anti-wear tire limiting module includes vertical plates on the front and rear sides of both ends of the lifting frame. A second telescopic push rod is horizontally arranged on the vertical plate. The second telescopic push rod is provided with a mounting groove that is slidably connected to the top of the lifting frame. A bidirectional screw is rotatably arranged in the mounting groove in the front-rear direction. A drive motor for rotating the bidirectional screw is provided on the mounting groove. Mounting blocks that are slidably connected to the mounting groove are screwed to both sides of the bidirectional screw. A guard groove for positioning and fixing the tire in the front-rear direction is provided on the mounting block. An anti-wear component is also provided on the guard groove.
[0007] As a further improvement of this utility model, the retaining groove is also provided with a fixing groove for engaging and fixing with the mounting block, the fixing groove is provided with a fixing bolt for screwing and fixing the mounting block, and the mounting block is provided with a threaded fixing hole for screwing and connecting with the fixing bolt.
[0008] As a further improvement of this utility model, a mounting slider is also provided at the bottom of the mounting groove, and a mounting sliding hole is provided on the lifting frame to slide in connection with the mounting slider. Through the cooperation of the mounting slider and the mounting sliding hole, a sliding connection between the mounting groove and the lifting frame can be achieved.
[0009] As a further improvement of this utility model, the vertical cross-section of both the mounting slider and the mounting slide hole is T-shaped. This prevents the mounting slider from vertically shifting relative to the mounting slide hole and the lifting frame, and also avoids deformation and damage to the second telescopic push rod.
[0010] As a further improvement of this utility model, the anti-wear component is a protective pad disposed on the inner sidewall of the guard groove. The protective pad prevents the guard groove from contacting the tire's front-rear sidewall, thereby preventing damage to both the guard groove and the tire's front-rear sidewall.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Firstly, after the car is driven onto the lifting frame by climbing the ramp, the four tires of the car can be fixed by the modal limiting module to prevent the tires from moving independently relative to the lifting frame. Then, the lifting frame and the car can be moved upward together by the first telescopic push rod. The vertical insertion of the guide rod and guide hole can make the lifting frame move vertically smoothly and prevent the lifting frame from shifting laterally, and prevent the first telescopic push rod from being easily damaged by terrain deformation.
[0013] Secondly, the tire can be limited and fixed from the front and rear directions by the cooperation of the mounting groove, the first vertical screw, the drive motor, the mounting block and the guard groove. Attached Figure Description

Detailed Implementation
[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0022] like Figure 1 , 2As shown in Figure 5, a tire-wear-resistant lifting mechanism assembly includes a U-shaped base 101 set on the ground, with the opening of the base 101 facing forward. First telescopic push rods 102 are vertically arranged at the four corners of the base 101. A receiving cavity is provided in the ground to accommodate the fixed ends of the telescopic push rods. A U-shaped lifting frame 103 with an open front end is provided on the output shaft of the four first telescopic push rods 102. Climbing ramps 104, flush with the top of the lifting frame 103, are provided at the front ends of both ends of the base 101. A guide rod 105, vertically inserted and slidably connected to the base 101, is provided at the bottom of the lifting frame 103. The guide rod 105 is located at the side end of the first telescopic push rods 102 and within the receiving cavity. A guide hole 106, slidably connected to the guide hole 106, is provided on the base 101. A tire-wear-resistant limiting module for limiting the tires of a vehicle is also provided on the lifting frame 103.
[0023] like Figure 3 As shown, the anti-wear tire limiting module includes vertical plates 201 on the front and rear sides of both ends of the lifting frame 103. A second telescopic push rod 202 is horizontally arranged on the vertical plates 201. The second telescopic push rod 202 has a mounting groove 203 that is slidably connected to the top of the lifting frame 103. A bidirectional screw 204 is rotatably arranged in the mounting groove 203 in the front-rear direction. A drive motor 205 for rotating the bidirectional screw 204 is provided on the mounting groove 203. Mounting blocks 206, slidably connected to the mounting groove 203, are screwed to both sides of the bidirectional screw 204. The mounting blocks 206 have retaining grooves 207 for positioning and fixing the tire in the front-rear direction. Anti-wear components are also provided on the retaining grooves 207. The inner walls of the retaining grooves 207 and the anti-wear components are both arc-shaped.
[0024] First, the car is driven up the ramp 104 onto the lift 103. Then, the car is stopped and the engine is turned off. After that, the second telescopic push rod 202 drives the guard groove 207 to move to the front and rear sides of the corresponding tires. The drive motor 205 is started to rotate the bidirectional screw 204, driving the mounting blocks 206 on both sides to move closer to each other until the guard groove 207 and the anti-wear components on both sides abut against the front and rear ends of the tires, thereby preventing the car tires from shifting in the front and rear direction relative to the lift 103.
[0025] Then, the four first telescopic push rods 102 can be activated, causing the lifting frame 103 and the car to move upward together. During this process, the vertical insertion and cooperation of the guide rod 105 and the guide hole 106 allows the lifting frame 103 to move vertically smoothly, preventing the lifting frame 103 from shifting laterally and preventing the first telescopic push rods 102 from being easily damaged by terrain changes.
[0026] According to another embodiment of the present invention, such as Figure 3As shown, the retaining groove 207 is also provided with a fixing groove 209 for engaging and fixing with the mounting block 206. The fixing groove 209 is provided with a fixing bolt 210 for screwing and fixing the mounting block 206. The mounting block 206 is provided with a threaded fixing hole for screwing and connecting with the fixing bolt 210.
[0027] Simply engage the fixing slot 209 with the mounting block 206, and then pass the fixing bolt 210 through the side wall of the fixing slot 209 and screw it into the threaded fixing hole to achieve flexible fixation of the retaining groove 207 and the mounting block 206. Simply separate the fixing bolt 210 from the threaded fixing hole to release the fixation between the retaining groove 207 and the mounting block 206, and the retaining groove 207 can be removed for replacement of the worn anti-wear component and the retaining groove 207 together.
[0028] According to another embodiment of the present invention, such as Figure 1 , 3 As shown in Figure 4, a mounting slider 302 is also provided at the bottom of the mounting groove 203, and a mounting sliding hole 301 is provided on the lifting frame 103 to slide and connect with the mounting slider 302. Through the cooperation of the mounting slider 302 and the mounting sliding hole 301, the mounting groove 203 and the lifting frame 103 can be slidably connected.
[0029] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, both the mounting slider 302 and the mounting hole 301 have T-shaped vertical sections. This prevents the mounting slider 302 from shifting vertically relative to the mounting hole 301 and the lifting frame 103, and also prevents the second telescopic push rod 202 from deforming and being damaged.
[0030] According to another embodiment of the present invention, such as Figure 3 As shown, the wear-resistant component is a protective pad 208 disposed on the inner wall of the guard groove 207. This allows the protective pad 208 to directly contact the front and rear ends of the tire, preventing the guard groove 207 from contacting the tire's front-rear sidewalls, thus avoiding damage to the guard groove 207 and the tire's front-rear sidewalls. The inner wall of the protective pad 208 is curved.
[0031] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
