Embodiment Construction

[0014] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0015] The main functions of the pick friction and wear test device of the present invention include that the angle of the test pick relative to the grinding wheel is adjustable, the pressure of the pick relative to the grinding wheel is adjustable, and the linear velocity of the pick relative to the grinding wheel is adjustable. The device of the present invention comprises seven parts, such as figure 1 , namely drive assembly, loading assembly, clamping assembly, grinding wheel assembly, protection assembly, transmission assembly and frame assembly. The rack assembly is the foundation of the equipment, and other components are installed on the rack assembly. The motor of the drive assembly drives the grinding wheel assembly to rotate through the transmission assembly, and the motor adopts frequency conversion to control the speed to achieve the ...

Abstract

The invention belongs to the technical field of pick performance test in coal mine machinery, in particular relates to a pick friction and wear testing device, and solves the problems of existing pick performance evaluation. The device includes a driving component, a loading component, a clamping component, a grinding wheel component, a transmission component and a rack component. The driving component drives the grinding wheel component to rotate through the transmission component, the loading component includes a hydraulic cylinder, the hydraulic oil cylinder is connected with the clamping component, and the clamping component is equipped with a test pick capable of adjusting sliding and rotation positions. The invention realizes the friction and wear test of pick at different installation angles, cutting velocity and pressure, and can detect the wear resistance of the pick under the working conditions of installation angle of 0-90 DEG, linear velocity of 0-5 m / s and the pressure of 0-30 kN; at the same time, the device provided by the invention is also base equipment for studying pick working state, and can provide the basic test data for optimization design of pick parameters and design of operating mechanism of digging machinery.

Description

technical field [0001] The invention belongs to the technical field of coal mine mechanical pick performance test, and in particular relates to a pick friction and wear test device. Background technique [0002] Picks are widely used working parts in coal mining machinery. They are mainly used in roadheaders, shearers and other equipment. As the main consumables in the production process of mines, wear is the main failure mode. Therefore, the wear resistance of picks has a great impact on The performance of mining equipment, mine production capacity and economic benefits all have a great influence. At present, the parameters such as materials, heat treatment methods and structural forms used by various pick manufacturers are quite different, resulting in different performances. Correctly evaluating the wear resistance of picks is of great significance for the design of mining machinery and the actual production of mines. [0003] At present, the pick performance test genera...
