Abstract
Description
Technical Field
[0001] The utility model relates to a friction lining and belongs to the technical field of friction linings. 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] Deviations in the groove diameter of the friction linings of multi-rope friction hoists, differences in the mechanical properties of the friction linings, variations in the length of the suspension wire ropes, and variations in the mechanical properties of the different wire ropes themselves are among the primary factors that can disrupt the balanced tension of the wire ropes. Unbalanced wire rope tension can lead to increased wear of the linings, rapid breakage of wires and strands in the highly tensile wire ropes, shortening their service life and even causing serious accidents such as tilting of the hoisting vessel and jamming of the hoist. The Coal Mine Safety Regulations stipulate that the difference between the tension of any individual wire rope and the average tension must not exceed ±10%. Therefore, the ability to accurately and effectively measure this difference in real time and report the results is an urgent issue. Utility Model Content
[0004] The purpose of the utility model is to provide a friction pad to solve the technical problems existing in the prior art as mentioned above.
[0005] The technical solution provided by the utility model is as follows: a friction pad, comprising a plurality of friction linings, wherein the friction linings include a friction lining body, a pressure guide column and a pressure sensor, a rope groove is provided on the friction lining body, the rope groove is used to place a steel wire rope, one end of the pressure guide column extends into the rope groove and contacts the steel wire rope, and is used to transmit the pressure of the steel wire rope, and the other end of the pressure guide column is connected to the pressure sensor, and is used to transmit the pressure to the pressure sensor.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows:
[0007] Furthermore, the pressure guide column is slidably connected to the inner surface of the friction lining, so as to prevent the friction between the pressure guide column and the friction lining from affecting the accuracy of the pressure transmission of the pressure guide column.
[0008] Furthermore, the pressure sensor is located inside the friction pad body, and the pressure sensor is used to detect and convert a pressure signal.
[0009] Furthermore, the bottom curvature of the friction lining is the same as the peripheral curvature of the friction wheel.
[0010] Furthermore, the friction lining is made of wear-resistant material to improve the durability of the wear-resistant lining.
[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:
[0012] The utility model sets a pressure sensor on the friction lining, so that the hoist can measure and report the current tension and the tension balance status of multiple wire ropes in real time in both static and running states, which helps to adjust the running time and running value of the hoist, reduce adjustment auxiliary time, improve production capacity and economic benefits, reduce uneven wear of the friction lining, reduce the number of rope groove maintenance times, and extend the service life of the friction lining. The wire rope tension balance helps to reduce the occurrence of wire rope breakage and other diseases, extend the service life of the wire rope, and can improve the lifting capacity and safety performance of the hoist, reduce the occurrence of major production safety accidents, and at the same time, the tension is measured and reported in real time, which is convenient for improving the management level of mine hoists and meeting the national smart mine construction needs.

[0017] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.
[0018] like Figure 1-3As shown, a friction pad includes multiple friction pads, and the friction pads include a friction pad body 1 and a pressure guide column 2 and a pressure sensor 3 arranged inside the friction pad. The friction pad body 1 is provided with a rope groove, and the rope groove is used to place a wire rope 4. One end of the pressure guide column 2 extends into the rope groove and contacts the wire rope 4, and is used to transmit the pressure of the wire rope 4. The other end of the pressure guide column 2 is connected to the pressure sensor 3, and is used to transmit the pressure to the pressure sensor 3; the pressure sensor 3 outputs the pressure signal to the signal collector, and the signal collector processes and calculates multiple pressure signals, determines which pressure sensor 3 exceeds the allowable range, and then performs corresponding setting processing, so as to monitor the tension and balance state of the wire rope 4 in real time, reduce the uneven wear of the friction pad, extend the service life of the wire rope 4 and the friction pad, and reduce the occurrence of safety accidents. The pressure guide column 2 is slidably connected to the inner surface of the friction lining. The pressure guide column 2 is made of a material with a small friction coefficient to avoid the friction between the pressure guide column 2 and the friction lining affecting the accuracy of the transmitted pressure; the bottom curvature of the friction lining is the same as the outer peripheral curvature of the friction wheel, so that the friction lining and the friction wheel can be fit together. The friction lining is made of wear-resistant material to improve the durability of the wear-resistant lining.
[0019] When the friction pad of the present invention is used, first the fixed end of the wire rope 4 of the hoist is fixedly connected to the load, the hoist is started to lift the load, and during the lifting process, the pressure of the load is transmitted to the pressure guide column 2 through the wire rope 4; the pressure guide column 2 then transmits the pressure to the pressure sensor 3; after the pressure sensor 3 detects the pressure change, it outputs an electrical signal through the signal conversion unit, and after the signal collector receives the electrical signal, it processes multiple pressure signal values to determine which pressure sensor 3 exceeds the allowable range, and then corresponding processing can be performed to ensure the safety of the hoist operation.
[0020] The pressure sensor 3 needs to be uniformly calibrated on a measuring platform before installation, so that inaccurate signal acquisition will not occur due to errors of the pressure sensor 3 during subsequent use.
[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
