Double-motor cutting-part loading test device of roller-type coal mining machine

Abstract

The invention discloses a double-motor cutting-part loading test device of a roller-type coal mining machine, which belongs to the technical field of a coal mining machine, and the double-motor cutting-part loading test device comprises a tested double-motor cutting part, a connecting lug supporting frame, a planet head supporting frame, a test connecting sleeve, a universal coupler and a torque loading device, one end of the tested double-motor cutting part is connected with the connecting lug supporting frame, the other end is connected with a second planet heat supporting frame, the test connecting sleeve is installed between a first planet head supporting frame and the second planet head supporting frame, the torque loading device is connected with the universal coupler, and a single-motor cutting part is installed between the connecting lug supporting frame and the planet head supporting frame. The double-motor cutting-part loading test device has beneficial effects that the single-motor cutting part is used for substituting the double-motor cutting part to be connected with the torque loading device, and only one set of torque loading device and one corresponding universal coupler are needed, so that the structure is simple, the test cost is effectively reduced, the test installation time can be shortened, the working efficiency can be improved, and an ideal test effect can be achieved.

Description

technical field [0001] The invention relates to a loading test device for a cutting part of a coal shearer, in particular to a loading test device for a double-motor type cutting part of a drum shearer, which belongs to the technical field of coal mining machines. Background technique [0002] The cutting part of the shearer is the main functional part of the shearer, which undertakes the tasks of cutting and dropping coal. The power of the cutting part accounts for more than 80% of the total power of the shearer. In view of the importance of the cutting part of the coal shearer, a loading test must be done before the cutting part is put into use. [0003] The traditional dual-motor cutting section loading test device (such as figure 1 ) Two sets of torque loading devices for the cutting part are required, and two input shafts are used to input them to the input ends of the double-motor cutting part respectively, and then the test connection sleeve is used to connect anothe...
