Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of lifting appliance, concretely relates to a car coupler adjusting lifting appliance. BACKGROUND
[0002] The magnetic particle flaw detection of the car coupler is carried out in a flaw detection well, so the car coupler needs to be lifted and put into the well, and the car coupler is lifted by a rope before, and such lifting mode has two defects: one is that the rope lifting is not firm and is easy to cause the car coupler to fall off, and the situation of hurting people and equipment occurs; the other is that the rope shields the surface of the car coupler and causes the flaw detection to have a loophole. CONTENT
[0003] The utility model aims at providing a car coupler adjusting lifting appliance, the lifting of the car coupler is realized through the special lifting appliance, and the flaw detection process is safer and more comprehensive.
[0004] Technical scheme as follows:
[0005] The car coupler adjusting lifting appliance comprises a lifting ring, a lifting hook, a limiting groove, a hook head, a movable stopper and a movable stopper handle, the limiting groove is connected with the lifting hook through welding, and the lifting hook and the hook head are connected through bolts.
[0006] Further, the total width of the lifting hook and the movable stopper is 220-230mm.
[0007] Further, the inside of the hook body is a cavity structure, and the tail part is a square opening with a size of 180-190.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] 1. The utility model discloses the traditional rope lifting, uses the special lifting appliance lifting, so the lifting is more firm.
[0010] 2. Because the traditional rope lifting shields the surface of the car coupler workpiece and is easy to cause the flaw detection to be incomplete, so the special lifting appliance of the utility model can make the flaw detection more complete. DRAWINGS

[0017] The following description fully illustrates specific embodiments of the utility model to enable one of ordinary skill in the art to practice and reproduce the same.
[0018] The car hook adjusting lifting appliance comprises a lifting ring 1, a lifting hook 2, a limiting groove 3, a hook head 5, a movable stopper 4 and a movable stopper handle 6, the limiting groove 3 is connected with the lifting hook 2 through welding, and the lifting hook 2 and the hook head 5 are connected through bolts.
[0019] The lifting hook 1 is connected with a hoisting device and plays a role of lifting a workpiece.
[0020] The lifting hook 2 and the hook head 5 are connected through bolts, and the width of the lifting appliance can be adjusted by adjusting the position of the hook head.
[0021] The total width of the lifting hook 2 and the movable stopper 4 is 220-230 mm.
[0022] The hook body of the car hook is a cavity structure, the tail part is small in size and large in internal cavity, and the tail part is a square opening with a size of 180-190.
[0023] The movable stopper 4 plays a role of stopping, and the lifting appliance can be separated from the car hook by lifting the movable stopper through the movable stopper handle 6, and the lifting appliance can be fastened with the car hook by putting down the movable stopper.
[0024] Fastening principle:
[0025] When the movable stopper is lifted, the width of the lifting hook 2 and the hook head 5 is 140 mm, which is smaller than the size of the tail part of the car hook, so that the lifting hook 2 is separated from the car hook; and when the movable stopper 4 is put down, the width of the lifting appliance is 222 mm, which is larger than the width of the tail part of the car hook, so that the lifting hook is connected with the car hook.
[0026] The use process is as follows:
[0027] S1, the movable stopper 4 is lifted by using the movable stopper handle 6;
[0028] S2, the lifting appliance is put into the hollow interior of the car hook, and the hook head 5 is hooked to the edge of the tail part of the car hook;
[0029] S3, the movable stopper 4 is put down to make the hook head 5 be clamped with the tail part of the car hook, so that the hook head 5 cannot be separated;
[0030] S4, the movable stopper 4 is lifted to make the hook head 5 be separated from the tail part of the car hook.
[0031] The terms used in the present utility model are illustrative and not restrictive. Since the present utility model can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above examples are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims, and therefore all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
