Description

Technical Field

[0001] The utility model relates to the technical field of foundation brake assembly, and more specifically to a hook of a brake hub for assembling a foundation brake. Background Art

[0002] The basic braking device refers to the transmission part of the braking device of a locomotive vehicle, from the brake cylinder piston push rod to the brake shoe and a series of levers, pull rods, brake beams and so on. During the basic braking process, the braking device is lifted by a hook for easy later operation. The hook is a common lifting device in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of pulley blocks and other components. The lifting devices used for lifting include multi-claw lifting devices, L-shaped hooks, etc., which have a complex structure and are inconvenient to use, which greatly affects the lifting efficiency of the braking device.

[0003] After searching, the Chinese patent with publication number CN210825109U discloses a hook for a brake hub, which is formed by setting a longer lifting rod and a horseshoe-shaped hook, and the lifting rod and the hook are connected as a whole at an angle, and the hook includes a U-shaped groove, a left clamping plate and a right clamping plate distributed on both sides of the U-shaped groove. After adjusting the length of the adjusting screw, the U-shaped groove of the hook is clamped on the brake hub, and the lifting hook is lifted. The brake hub generates a torque on the hook due to its own gravity, that is, the hook generates an upward prying torque on the brake hub, so that the brake hub will not fall and the brake hub is lifted.

[0004] However, when this structure is actually used, the gravity of the brake hub itself is used to generate a lever force, so that the brake hub is stuck in the hook for fixation. When the structure shakes, the lever force is damaged and the brake hub is easily removed from the hook, thereby affecting the use effect and posing a safety hazard. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a hook for assembling a brake hub of a foundation brake to solve the problems raised in the above background technology.

[0013] By adopting the above technical solution: in order to improve the anti-slip effect, secondary protection is also done, thereby further improving safety and reducing the risks of pinching and smashing.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a fixing mechanism, compared with the prior art, the movable plate is moved upward to open the hook body, one side of the brake device is placed on the hook body, and then the movable plate is moved downward, thereby driving the limit plate to move downward, and the handle is rotated counterclockwise, thereby driving the screw to rotate counterclockwise, thereby driving the movable plate to move to the side away from the handle, so that the limit plate on one side of the movable plate is clamped on the surface of the brake device for preliminary fixation, thereby eliminating the need for manual handling, reducing physical harm to employees, and the operation is convenient and simple, and can be completed by one person, reducing manpower allocation;

[0016] 2. By setting the hanging rod, lever hanging seat, auxiliary strip and anti-slip strip, compared with the prior art, the guide strip is inserted into the inside of the placement groove and then welded and fixed. Therefore, when installing the guide strip and the lever hanging seat, since the two sides of the lever hanging seat are convex and the middle is concave, it is convenient to guide, and the problem of difficulty in hole alignment is effectively solved. At the same time, the auxiliary strip fixes the other side of the braking device, making the fixation more firm. The braking device contacts the anti-slip strip on one side of the contact plate, which greatly improves the friction during the lifting process, thereby preventing the braking device from falling. It is in full automatic mode during transportation, which greatly improves safety and reduces the risk of pinching and smashing. BRIEF DESCRIPTION OF THE DRAWINGS
