[0001] The utility model relates to the technical field of steel rope or steel cable bearing parts, in particular to a combined friction lining. Background Art

[0002] Friction pad is a pad installed on the friction wheel of the friction hoist for mining. It is a very important component used by the friction hoist to drive the wire rope and lift the load. The friction pad bears the weight of the entire wire, the weight of the container, the weight of the cargo, the weight of the balance tail rope, and various dynamic loads and impact loads during operation. The quality of the friction performance will directly affect the working capacity and efficiency of the hoist.

[0003] In the existing friction pads, the pads are fixed on the friction wheel of the hoist by screws. The pads are of non-modular structure. When the pads are damaged, the entire pads need to be disassembled and replaced, which increases the cost of use. At the same time, it is also troublesome to disassemble and install the pads.

[0010] The clamping mechanism includes a control rod, a control handle, a rotating rod, a limit block, a connecting groove, a limit groove, a clamping top block and a spring.

[0011] Preferably, the control rod is rotatably connected to the bottom wall of the control slot, and the control rod is arranged on the lower side of the slot cover;

[0012] The control handle is fixedly connected to the upper end of the control rod, and the rotating rod is fixedly connected to the lower end of the control rod.

[0013] Preferably, the lower end of the rotating rod rotates and extends out of the lower side of the friction pad body, and the limit block is fixedly connected to the lower end of the rotating rod;

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the present invention provides a combined friction pad with the following beneficial effects:

[0021] (1) The combined friction pad, when the control handle is turned, the control handle will release the clamping limit between the limit groove and the limit block after transmission, and then the friction pad body can be removed and replaced by pulling it upward. When installing, the limit block is aligned with the connecting groove and moved downward. After the limit block moves to the inside of the limit groove, the control handle is turned. According to the above, the limit block will also rotate, and then the limit block will no longer be adapted to the connecting groove, and then the limit block will be clamped inside the limit groove. In this way, the friction pad body can be connected together by a combined clamping method, so that when a part of the pad is damaged, it only needs to release the clamping of this part of the pad to replace it, so that there is no need to replace the entire pad, thereby reducing the use cost of the friction pad.

[0022] (2) After the installation of the combined friction pad body is completed, the spring will push the clamping top block to move upward, and then the clamping top block will push the limit block to move upward, so that the limit block will fit with the top wall of the limit groove, and the limit block will not rotate by itself during the working process, thereby ensuring the stability of the clamping mechanism.

[0027] 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.

[0028] See also Figures 1 to 3 The utility model provides a new technical solution: a combined friction pad, including a mounting base 1, a friction pad main body 2 is arranged on the upper side of the mounting base 1, and two wire rope grooves 3 are integrally formed on the outer surface of the friction pad main body 2, and the two wire rope grooves 3 are arranged in front and behind.

The limit block 9 is fixedly connected to the lower end of the rotating rod 8. The limit block 9 is in the shape of a rectangular block. The connecting groove 10 is opened on the upper side of the mounting base 1. The connecting groove 10 is a rectangular groove adapted to the limit block 9. The limit groove 11 is opened inside the mounting base 1. The interior of the limit groove 11 is connected with the interior of the connecting groove 10. The limit block 9 cooperates with the limit groove 11 to form a card connection. The clamping top block 12 is fixedly connected to the inside of the limit groove 11.

[0030] Furthermore, when the friction pad main body 2 is worn and needs to be replaced, the staff first removes the slot cover 5, and then the structure inside the control slot 4 will be exposed, and then the control handle 7 is turned, and the control handle 7 drives the control rod 6 to start rotating synchronously, and the control rod 6 drives the rotating rod 8 to start rotating synchronously, and the rotating rod 8 drives the limit block 9 to start rotating synchronously, and the limit block 9 rotates inside the limit slot 11.
