Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for welding automobile bodies. Background Technology

[0002] Box trucks rely on their cargo boxes to transport goods. The main materials for the cargo boxes include corrugated iron, color steel plates, flat aluminum plates, and corrugated aluminum alloy. In the actual processing, multiple steps are required, such as forging, bending, and welding. During the welding process, in order to facilitate the placement of the cargo box panels, corresponding hook assemblies are usually used to lift the cargo box panels.

[0003] However, traditional hoisting methods mostly involve first securing the truck bed with straps, and then using a hook assembly in conjunction with a crane to lift the straps and complete the hoisting of the truck bed. In the above process, the straps are mostly directly hooked to the hooks. Thus, during the hoisting process, when the truck bed is affected by external forces or improper securing of the truck bed causes uneven stress in various parts, the straps located at the hooks are prone to slippage, affecting the stability of the hoisting process. Therefore, this utility model proposes a hoisting device for welding truck beds to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology that when the car body is affected by external forces or improper restraints cause uneven stress on various parts of the car body during the hoisting process, the straps at the hook part are prone to slippage, which affects the stability of the hoisting process. Therefore, a hoisting device for welding car bodies is proposed.

[0030] Reference Figures 1-4 A lifting device for welding automobile bodies, comprising:

[0031] Main frame 1;

[0032] Sliding bracket 2, there are four sliding brackets 2, and the four sliding brackets 2 are slidably connected to the left and right sides of the bracket respectively;

[0033] There are two sets of adjusting and fixing mechanisms, with the adjusting mechanism cooperating with the fixing mechanism and the sliding frame 2 respectively.

[0034] The hoisting mechanism consists of four sets, including: sleeve 3, electric push rod 4, and lifting rod 5;

[0035] The sleeve 3 is fixedly connected to the sliding frame 2, the electric push rod 4 is fixedly connected to the sliding frame 2, the output shaft of the electric push rod 4 extends to the inside of the sleeve 3, the output shaft of the electric push rod 4 is fixedly connected to the hanger 5, and the hanger 5 is slidably connected to the inside of the sleeve 3.

[0036] With the above structure, by adjusting the distance between the two sliding frames 2, the two sliding frames 2 can be adapted to various models and sizes of carriages. There are four sliding frames 2, which can be used to lift the carriages from both sides, so that the carriages are evenly stressed during lifting, do not shake, have high stability, and are quick and convenient.

[0037] As a preferred embodiment of this utility model, the adjustment mechanism includes: a rotating frame 6, a threaded rod 7, a driving gear 8, a power gear 9, and a crank handle 10;

[0038] The rotating frame 6 is fixedly installed on the top of the main frame 1. The outer side of the threaded rod 7 is rotatably connected to the inner side of the rotating frame 6. The two ends of the threaded rod 7 are respectively threadedly connected to the two sliding frames 2. The driving gear 8 is fixedly sleeved on the outer side of the threaded rod 7. The power gear 9 is fixedly connected to the crank handle 10. The crank handle 10 is rotatably connected to the inner side of the rotating frame 6. The power gear 9 meshes with the driving gear 8. A rectangular through hole is opened on the crank handle 10. After the crank handle 10 is rotated, the crank handle 10 can drive the power gear 9 to rotate. The power gear 9 then drives the threaded rod 7 to rotate. The threaded rod 7 can drive the two sliding frames 2 to move closer to each other, thereby adjusting the distance between the two sliding frames 2 and the position of the two lifting rods 5, thus adjusting the lifting position of the two lifting rods 5 on the car body.

[0039] As a preferred embodiment of the present invention, the fixing mechanism includes: a positioning ring 11, a positioning rod 12 and a spring 13;

[0040] The positioning ring 11 is fixedly installed on the rotating frame 6. The positioning rod 12 is slidably connected to the crank handle 10. The spring 13 is fixedly connected to the crank handle 10. After the positioning rod 12 and the positioning ring 11 are engaged, the positioning rod 12 can block the crank handle 10 from rotating, so that the crank handle 10 cannot rotate, preventing the crank handle 10 from being accidentally touched, and preventing the threaded rod 7 from being affected by external factors, thereby affecting the position of the sliding frame 2.

[0041] As a preferred embodiment of this utility model, the inner side of the positioning ring 11 is provided with a plurality of positioning grooves arranged at equal intervals. The rear end of the positioning rod 12 can be detachably engaged with the inner wall of the positioning groove. After the positioning rod 12 is inserted into the inner side of the positioning groove, the positioning rod 12 can prevent the crank handle 10 from rotating.

[0042] As a preferred embodiment of this utility model, the outer side of the positioning rod 12 is slidably connected to the inner wall of the rectangular through hole, and the spring 13 is fixedly connected to the inner wall of the rectangular through hole. The spring 13 is used to reset the position of the positioning rod 12, so that the positioning rod 12 can automatically block the rotation of the crank handle 10.

[0043] As a preferred embodiment of this utility model, movable through holes are provided on both the left and right sides of the bracket. The two sliding frames 2 are slidably connected to the inner walls of the two movable through holes respectively. The movable through holes allow the sliding frames 2 to move on the main frame 1 to adjust the distance between the two sliding frames 2.

[0044] It should be noted that the specific model of electric linear actuator 4 to be used is to be selected by those skilled in the art, and the electric linear actuator 4 mentioned above is all existing technology, which will not be elaborated on in this solution.

[0045] The working principle of this utility model is as follows: When the carriage needs to be hoisted, the gantry frame is used to drive the support to move, and then the support is moved to the top of the carriage. The sliding frame 2 moves to both sides of the carriage. Then, the electric push rod 4 is activated, which pushes the lifting rod 5 to insert into the inside of the carriage, driving the gantry frame to move the main frame 1. The main frame 1 and the sliding frame 2 can then lift the carriage, realizing the hoisting of the carriage. There are four sliding frames 2, which can hoist both sides of the vehicle, making the carriage evenly stressed during hoisting, preventing swaying and ensuring high stability. When the distance between the two sliding frames 2 on one side is not appropriate and needs to be adjusted, first pull the positioning rod 12 to disengage from the positioning ring 11, unlock the crank handle 10, and then turn the crank handle 10. Then, the crank handle 10 drives the power gear 9 to rotate, which in turn drives the threaded rod 7 to rotate. The threaded rod 7 then drives the two sliding frames 2 to move closer together, thus adjusting the distance between the two sliding frames 2 and the position of the two lifting rods 5. This adjusts the lifting position of the two lifting rods 5 on the car body. After adjustment, the positioning rod 12 is released, allowing it to automatically engage with the positioning ring 11. Once engaged, the positioning rod 12 prevents the crank handle 10 from rotating, thus preventing accidental activation of the crank handle 10 and preventing the threaded rod 7 from being affected by external factors, which could affect the position of the sliding frames 2. This greatly increases the stability of the sliding frames 2, allowing for stable lifting of the car body using the sliding frames 2.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
