Description

Technical Field

[0001] The utility model specifically relates to the technical field of galvanizing of automobile parts, in particular to a galvanizing gantry line for automobile parts. Background Art

[0002] Galvanizing of auto parts can bring many benefits to auto parts. The galvanized layer can provide excellent corrosion resistance. Auto parts will face various harsh environmental conditions during use, such as humid and high-salt air, chemicals on the road, etc. The galvanized layer can effectively prevent these factors from eroding the parts and extend the service life of the parts. Galvanizing can also increase the wear resistance of the parts. During the operation of the car, some parts will constantly rub and collide. The galvanized layer can reduce wear and maintain the size and shape accuracy of the parts.

[0003] At present, traditional galvanizing equipment uses large overhead cranes to lift the hangers when galvanizing auto parts. The traditional lifting device is large in size, so it can only install one device. When the equipment fails or needs maintenance, it needs to be shut down, which makes it impossible to effectively carry out the galvanizing work, reducing the working efficiency of the equipment.

In addition, the device in the above patent can only spray one liquid. However, in the galvanizing process, it is necessary to effectively react the automotive parts with different liquids. However, the structure in the above patent cannot effectively meet the needs of galvanizing. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 In an embodiment of the present invention, a galvanizing gantry line for automotive parts includes a galvanizing solution pool 1; a plurality of galvanizing solution pools 1 are provided; a frame 2 is provided outside the galvanizing solution pool 1; a plurality of gantries 3 are mounted on the frame 2; the gantries 3 include two symmetrically arranged mobile frames 33; L-shaped frames 314 are fixedly mounted on the four corners of the mobile frames 33; rollers 34 are mounted on the bottoms of the plurality of L-shaped frames 314; the rollers 34 are located on both sides of the support beam of the frame 2;

[0028] A measuring rod 30 is fixedly installed between the two movable frames 33 ; the top of the measuring rod 30 is fixedly installed with the top beam 311 .

[0029] More specifically, the two measuring struts 30 are arranged in a C shape; a screw rod 32 is installed inside each of the measuring struts 30; a lifting frame 31 is movably installed between the two screw rods 32; a plurality of hooks 310 are integrally provided on one side of the lifting frame 31; the hook 310 is installed in close contact with the hanger 4.

[0030] By adopting the above technical solution, when in use, the hanger 4 is mounted on the hook 310 on one side of the lifting frame 31. By rotating the screw rod 32, the lifting frame 31 drives the hanger 4 to be immersed in different galvanizing solution pools 1. A reaction occurs between the hanger 4 and the different liquids, effectively ensuring the galvanizing quality of the automotive parts.

[0031] In this embodiment, the two movable frames 33 are both equipped with driving wheels 39. The driving wheels 39 are provided in two groups. One group of driving wheels 39 is respectively equipped with a first driving shaft 312 and a second driving shaft 313 and a reducer, and the other group of driving wheels 39 is movably connected by a connecting rod 316. The driving wheels 39 are in contact with the top surface of the support beam of the frame 2.

[0032] The reducer and the mobile drive motor 36 are fixedly mounted in the middle of the first U-shaped frame 35; both ends of the first U-shaped frame 35 are fixedly mounted to the mobile frame 33; the connecting rod 316 is cooperatively mounted inside the second U-shaped frame 38; both ends of the second U-shaped frame 38 are fixedly mounted to the mobile frame 33;

[0033] By adopting the above technical solution, during the galvanizing process, the first drive shaft 312 and the second drive shaft 313 are driven by the mobile drive motor 36 to rotate in the same direction. The drive wheels 39 installed at the ends of the first drive shaft 312 and the second drive shaft 313 rub against the top surface of the frame 2 to drive the movable frame 33 to move forward and backward. During the movement, the rollers 34 installed on the L-shaped frame 314 contact the side of the frame 2, effectively preventing the movable frame 33 from deflecting during the movement.

[0034] In this embodiment, two symmetrically arranged guide rods 315 are installed between the top beam 311 and the lifting frame 31;

[0035] Among the two measuring struts 30, a lowering drive motor 37 is fixedly mounted on the top of one of the measuring struts 30; the lowering drive motor 37 is fixedly mounted to the screw rod 32 inside the measuring strut 30;

[0036] By adopting the above technical solution, during the galvanizing process, the gantry 3 drives the hanger 4 to pass through different galvanizing solution pools 1 in sequence, so that the auto parts on the hanger 4 react with different solutions, effectively ensuring the quality of galvanizing;

[0037] Furthermore, multiple gantries 3 can be installed on the frame 2. In this way, when one of the gantries 3 fails or needs maintenance during use, the remaining gantries 3 can effectively complete the galvanizing effect of automobile parts, thereby improving work efficiency.

[0038] The working principle of the present invention is as follows: when in use, the hanger 4 is mounted on the hook 310 on one side of the lifting frame 31. By rotating the screw rod 32, the lifting frame 31 drives the hanger 4 to be immersed in different galvanizing solution pools 1. A reaction occurs between the hanger 4 and the different liquids, effectively ensuring the galvanizing quality of the automotive parts.

[0039] When the galvanizing process is being carried out, the lifting frame 31 is first driven by the screw rod 32 to move the hanger 4 to a safe position, and then the position of the hanger 4 is moved by the rolling of the driving wheel 39. The reducer is driven by the mobile driving motor 36 to drive the first driving shaft 312 and the second driving shaft 313 to rotate in the same direction. The driving wheels 39 installed at the ends of the first driving shaft 312 and the second driving shaft 313 rub against the top surface of the frame 2 to drive the moving frame 33 to move forward and backward. During the movement, the contact between the rollers 34 installed on the L-shaped frame 314 and the side of the frame 2 effectively prevents the moving frame 33 from deviating during the movement.

[0040] During the galvanizing process, the gantry 3 drives the hanger 4 to pass through different galvanizing solution pools 1 in sequence, so that the auto parts on the hanger 4 react with different solutions. The galvanizing solution pool 1 includes a degreasing solution, a pickling solution, an activation solution, a galvanizing solution, a passivation solution, a sealing solution, etc. In this way, during the galvanizing process, impurities on the surface of the auto parts are effectively removed and galvanized. After the galvanizing process is completed, the protective performance of the galvanized layer on the auto parts can be further improved, and the gaps in the smile can be filled.

[0041] A plurality of gantries 3 can be installed on the frame 2. In this way, when one of the gantries 3 fails or needs maintenance during use, the remaining gantries 3 can also effectively complete the galvanizing effect of automobile parts, thereby improving work efficiency.
