Description

TECHNICAL FIELD

[0001] The utility model relates to the field of industrial electroplating, especially to a bearing beam anti-shaking support. BACKGROUND

[0002] In the electroplating production process, the workpiece needs to be frequently transported between multiple processing procedures. The traditional workpiece bearing device usually adopts a simple hook type structure. Due to the lack of effective locking mechanism, the bearing device is prone to shaking due to inertia or air flow during the crane lifting process, which may cause workpiece collision damage or electrolyte splashing. Moreover, the existing anti-shaking device adopts a rigid fixed structure, which is prone to mechanical fatigue during frequent start-stop process, resulting in connection failure. Although there are some improved anti-shaking supports in the prior art, such as reducing shaking by adding counterweight or damper, these solutions have the problems of complex structure and high maintenance cost. For example, the patent with publication number CN209685936U discloses a crane flying target anti-shaking device, which still has the following problems in anti-shaking: the guide frame needs to be adapted to a specific flying target and hanger, and has poor compatibility for products of different sizes or shapes, which may need customized modification. SUMMARY

[0003] (I) Technical problem solved

[0004] In view of the deficiencies of the prior art, the utility model aims to provide a bearing beam anti-shaking support, which solves the problems existing in the prior art. The traditional rigid hanger is prone to pendulum effect during lifting process, especially when the crane starts and stops, which aggravates the shaking. The present patent realizes multi-directional anti-shaking through the locking mechanism. The telescopic rod and locking plate in the locking device can form mechanical locking with the crane hook, preventing vertical movement. The mechanical transmission design of the lever can automatically trigger the locking action when the hook is contacted, without manual intervention. Moreover, the present patent realizes automatic clamping with the hook of the crane during lifting operation, and automatic unlocking with the hook after being put down.

The hook of the crane is directly inserted into the interior of the support beam 1 to lift the entire device along with the workpiece. The locking mechanism 2, through the cooperation of various parts, can lock and unlock with the crane hook to prevent the device from swaying during transportation. The connecting beam 3 is fixed to the lower end of the support beam 1 and is used to connect the support beam 1 and the hanger 4. The hanger 4 is fixed to the lower end of the connecting beam 3 and is used to suspend the workpiece to be electroplated, so that the workpiece can be transferred between various electroplating processes.

The second circular hole 2043 is used to fix the lever 204 to the first rotating shaft 2014 at the upper end of the sliding block 201.

[0028] Working principle:

[0029] In the process of transporting the workpiece, the trolley hook extends into the inside of the carrying beam 1, specifically on the locking plate 2068, in the process of slow lifting, when the weight of the device applied on the sliding block 201 decreases, the elastic force of the second spring 20610 is greater than that of the first spring 203, the second spring 20610 pushes the locking plate 2068 in the lock 206 to move upward and clamp the hook, thereby pushing the lever 204 to squeeze the sliding block 201 downward, at this time, the first spring 203 is compressed, and the sliding block 201 moves downward to the original position. The locking function is realized to prevent shaking.

[0030] After the workpiece is transported, the sliding block 201 is prevented on the wall on both sides of the electroplating tank, and as the trolley hook descends, the weight of the device gradually bears on the sliding block 201, and as the sum of the weight of the device and the first spring 203 gradually increases, the sliding block 201 is pushed to move upward, thereby pushing the lever 204 to squeeze the stressed plate 2065, at this time, the second spring 20610 is compressed, and the locking plate 2068 moves downward due to gravity, and the unlocking is realized.

[0031] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
