Description

Technical Field

[0001] The utility model relates to the technical field of pick teeth, in particular to a multifunctional pick tooth performance detection tool for coal mining machines. Background Art

[0002] Picks are widely used in coal mining machines. Picks have the characteristics of wear resistance, high rigidity and high strength, which makes them very suitable for crushing ore in coal mining machines and tunneling machines. Picks are generally fixed on the outside of the rotating turntable, and the rotation of the turntable drives the picks to crush coal seams and rock layers.

[0003] The performance of existing pick heads needs to be tested during the production process. Usually, the internal flux is tested to see if it is intact and whether there are bubbles. However, when testing the grinding performance of the pick heads on the spot, the produced pick heads need to be installed on coal mining machines and tested in different regions and mining areas. After the on-site testing, the testers need to bring the pick heads back for analysis. The back and forth and installation are quite troublesome. The grinding performance of the pick heads is mainly affected by stones. The pick heads cannot be adjusted during use. In order to improve the testing effect, we provide a multifunctional coal mining machine pick performance testing tool to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A movable mechanism 7 that can move left and right is provided in the driven wheel 13 and the shell 1. The movable mechanism 7 is fixed with a fixed ring 6, and the fixed ring 6 is provided with a clamping mechanism 8 for clamping different ores. A first motor 4 is fixed inside the shell 1, and a clamp 5 for clamping the pick head is fixed on the output shaft of the first motor 4. The center lines of the first motor 4 and the clamp 5 are at the same horizontal position as the center lines of the fixed ring 6, the second motor 11 and the active disk 10.

[0027] The above scheme uses the second motor 11 to drive the active disk 10 and the driven wheel 13 to rotate. The thread provided inside the driven wheel 13 and the cooperation with the thread on the surface of the movable mechanism 7 can enable the movable mechanism 7 and the clamping mechanism 8 to move left and right inside the shell 1, thereby clamping the cover plate 2 at the position of the ore, avoiding the operation of stopping the machine to move the ore, and avoiding the harm caused by the operator's contact with the internal machine during work.

[0028] Specifically, the movable mechanism 7 includes a fixed plate 701 evenly fixed around the fixed ring 6, bearings 702 fixed between the fixed plates 701, a rotating shaft 703 passing through the bearing 702, a threaded rod 704 fixed by the rotating shaft 703 passing through the fixed plate 701, the threaded rod 704 passes through the driven wheel 13 and the housing 1 in turn, and a limiting block 705 is fixed at one end of the threaded rod 704, and the threaded rod 704 is connected to the driven wheel 13 through a threaded connection. By adopting the threaded rod 704 in the movable mechanism 7 and the thread of the driven wheel 13, the entire movable mechanism 7 can be moved under the action of the rotating shaft 703 and the bearing 702, so that the position can be adjusted during grinding, thereby improving the overall grinding effect and facilitating the separation of the clamping mechanism 8 from the pick head in the later stage, so as to facilitate the removal of the pick head for measurement in the later stage.

[0029] Specifically, the clamping mechanism 8 includes a slide rod 802 that is inserted into the slide hole 14 of the fixed ring 6, a clamping plate 804 is fixed to the bottom end of the slide rod 802, an anti-slide plate 806 is provided at the bottom end of the clamping plate 804, and the anti-slide plate 806 is threadedly connected to the clamping plate 804 through a bolt 805, and the bolt 805 passes through the clamping plate 804 to adjust the distance between the anti-slide plate 806 and the clamping plate 804, a spring 803 is sleeved on the surface of the slide rod 802, the upper end of the spring 803 overlaps the inner wall of the fixed ring 6, and the lower end of the spring 803 Overlapping with the surface of the clamping plate 804, a top block 801 is fixed to the upper end of the slide bar 802. The spring 803 in the clamping mechanism 8 can lift the clamping plate 804 upward under the action of elastic force, and then the pick head to be tested can be placed under the clamping plate 804. At the same time, the bolt 805 and the anti-slip plate 806 can be used in combination to clamp the mining ore to be simulated, so that the pick head can continuously grind the ore, thereby testing the performance of the pick head under the ore and reducing the testing process in field use.

[0030] Specifically, the surface of the shell 1 is movably connected to a cover plate 2 via a hinge, and a handle is provided on the surface of the cover plate 2. A protective cover 3 is fixed to the side of the shell 1, and the protective cover 3 is provided at the position of the second motor 11.

[0031] Working principle: When in use, the operator opens the cover plate 2 upwards through the handle provided on the surface of the cover plate 2 under the action of the hinge, rotates the clamp 5 to place the pick head to be tested in the middle of the clamp 5 and fixes it, and then places the ore to be simulated in the anti-slip plate 806 between the clamping plates 804, and clamps the anti-slip plate 806 with the bolt 805. After fixing, start the second motor 11, and the second motor 11 drives the active disk 10 to rotate. The rotation of the active disk 10 will drive the driven wheel 13 between the track disk 9 to rotate, and the rotation of the driven wheel 13 will drive the threaded rod 704 to rotate through the internal thread. The threaded rod 704 rotates, and the cooperation between the bearing 702 at one end and the rotating shaft 703 pushes the fixed plate 701, the fixed ring 6 and the clamping mechanism 8 to move left and right. After adjusting the position, the first motor 4 is started, and the first motor 4 rotates to drive the clamped pick head to rotate and grind in the ore. The working time is set. During rotation, the elastic force of the spring 803 will gradually move the clamped ore closer to the pick head. After the rotation is completed, the pick head and the ore are taken out, the surface of the pick head is inspected, and the degree of wear of the ore is measured. The degree of wear of the pick head when working under the ore is analyzed by an external analysis instrument.
