Description

[0001] The utility model relates to the technical field of shearer for thin coal seams, in particular to a cutting motor fixing device for a shearer for thin coal seams. Background Art

[0002] With the deep exploitation of thin coal seam fields, it is required that the cutting power of the shearer suitable for this coal seam is large. However, due to the limitation of the height of the shearer on the coal seam working face, the rocker arm motor must not be a motor with too large power. In order to meet the cutting power requirement of the shearer, a large-power shearer for thin coal seams adopts the method of installing two motors on one rocker arm to increase the cutting power. The cutting motor is the power source of the rocker arm of the shearer, and the output shaft end of the cutting motor extends into the gear cavity of the rocker arm to transmit power to the gear.

[0003] In the installation process of the existing shearer cutting motor, it is connected by the way of being penetrated and fixed by multiple bolts. During installation, it is necessary to manually align the installation holes between the motor base and the installation seat inside the shearer one by one, and then penetrate the bolts. During the penetration process, since the bolts need to be fixed one by one, the forces on multiple positioning holes are inconsistent, resulting in the phenomenon of offset between the installation holes, which causes inconvenience to the installation.

At this time, the positioning rods 13 are squeezed to generate a locking phenomenon, so that the positioning rods 13 contract into the fixed base 4. When the cutting motor body 1 reaches the specified area, the push blocks 12 will move downward under the elastic force of the short springs 11, and then drive the positioning rods 13 to be in a clamped state with the corresponding positioning holes 14, so as to realize the initial fixed state of the cutting motor body 1 and play an important positioning role, reducing the phenomenon of position deviation of the bolts during the fixing process. And through the cooperation of the slide rail grooves 8 and the slide rail blocks 9, it is convenient for the fixed base 4 below the cutting motor body 1 to slide in, which can improve the installation efficiency and installation accuracy of the cutting motor body 1, making the installation steps more convenient.

And through the cooperation of the slide rail groove 8 and the slide rail block 9, it is convenient for the fixed base 4 below the cutting motor body 1 to slide in, which can improve the installation efficiency and installation accuracy of the cutting motor body 1 and make the installation steps more convenient;

[0032] After the cutting motor body 1 is installed on the inner wall of the shearer body, through the action of the torsion spring 15, it can drive the clamping plate 16 to rotate, so that one end of the clamping plate 16 is always in contact with the corresponding card slot 6, further improving the stability of the cutting motor body 1 during use and making it not easy to slide, thereby ensuring the firmness of the installation of the cutting motor body 1.
