Embodiment 1

[0053] A device for adjusting and simulating the space pose of the trough in the middle of the scraper conveyor, such as Figure 1-4 As shown, including a base 15, a support plate 4, a plurality of ball joints, a plurality of hydraulic cylinders and a PLC controller, the base 15 is placed on the ground;

[0054] The support plate 4 is an L-shaped plate made of a horizontal base plate and a vertical side plate, and the middle groove 1 of the scraper conveyor is placed on the horizontal base plate of the L-shaped plate;

[0055] The number of ball hinges is six, which are No. 1 ball hinge 5, No. 2 ball hinge 7, No. 3 ball hinge 9, No. 4 ball hinge 11, No. 5 ball hinge 2 and No. 6 ball hinge 13. The number of hydraulic cylinders There are also six hydraulic cylinders, No. 1 hydraulic cylinder 6, No. 2 hydraulic cylinder 8, No. 3 hydraulic cylinder 10, No. 4 hydraulic cylinder 12, No. 5 hydraulic cylinder 3 and No. 6 hydraulic cylinder 14, and they correspond to the ball hinges on...

Embodiment 2

[0061] A device for adjusting and simulating the space pose of the trough in the middle of the scraper conveyor, as described in Embodiment 1, the difference is that the L-shaped plate is a steel plate with a thickness of 5-10 mm.

Embodiment 3

[0063] A device for adjusting and simulating the pose of the slot in the middle of the scraper conveyor, as described in Embodiment 1, the difference is that the ball hinge includes a ball joint, a connecting rod fixedly connected to the ball joint, and a ball joint for accommodating the ball. The hinge base of the head, the connecting rod is connected with the piston rod of the corresponding hydraulic cylinder, and the hinge base is fixed on the four corners of the horizontal bottom plate or the end surface of one side of the middle groove near the vertical side plate of the L-shaped plate.

Abstract

The invention provides a device for adjusting and simulating the spatial pose of a middle groove of a scraper conveyor and a working method of the device, and belongs to the field of coal mine machineries. The device comprises a base, a supporting plate, six spherical hinges, six hydraulic cylinders and a PLC, the supporting plate is an L-shaped plate composed of a horizontal bottom plate and a vertical side plate, and the middle groove is placed on the horizontal bottom plate; the bottoms of the first to fourth hydraulic cylinders are all fixed to the base, piston rods of the first to fourthhydraulic cylinders are connected with one ends of the spherical hinges with the corresponding numbers respectively, and the other ends of the first to fourth spherical hinges are fixed to the four corners of a horizontal bottom plate of the L-shaped plate. The bottoms of the fifth hydraulic cylinder and the sixth hydraulic cylinder are fixed to vertical side plates of the L-shaped plates, and piston rods of the fifth hydraulic cylinder and the sixth hydraulic cylinder are connected with one ends of corresponding numbered spherical hinges. The first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder and the sixth hydraulic cylinder are all connected with the PLC and control piston rods of the hydraulic cylinders to stretch out and draw back through the PLC. According to the invention, the spatial pose of the middle groove under different complex geological and topographic conditions and in the pushing and sliding working process of the hydraulic support canbe adjusted and simulated.

Description

technical field [0001] The invention relates to a device and a working method for adjusting and simulating the spatial position and posture of a trough in the middle of a scraper conveyor, belonging to the technical field of coal mine machinery. Background technique [0002] The scraper conveyor is an important transportation equipment in the coal mining face of the coal mine at present. It is not only the running track of the coal mining machine, but also provides traction and guidance for the coal mining machine, and at the same time provides a connection point for the hydraulic support, so as to realize the hydraulic support along the Along with the advancing direction of the coal mining face, it keeps moving. However, due to the complex geological and topographical conditions in coal mines, the spatial pose of the trough in the middle of the scraper conveyor is complex and changeable, which has a great impact on the working performance of the scraper conveyor. In order ...
