Adding pads for support is relatively troublesome, and it is not easy to find suitable pads. In order to solve the above problems, a support device for maintenance of mining machinery is urgently needed. Utility Model Content

[0013] (III) Beneficial effects

[0014] The utility model provides a supporting device for maintenance of mining machinery, which has the following beneficial effects:

[0015] 1. A support device for maintenance of mining machinery has the effect of improving the support stability of the support device through the arrangement of the sleeve leg, the telescopic leg, the first positioning hole, the second positioning hole and the latch. When in use, the support device is placed at a suitable fulcrum under the machinery to be repaired. After placement, the first rotating block is rotated to the right by an iron rod, and the first rotating block drives the first screw rod to rotate. When the first screw rod rotates, it drives the moving block connected by the thread on the other side to move inward, and the movement of the moving block drives the first support leg and the second support leg to move. The connection moves inward, and the angles of the third supporting leg and the fourth supporting leg change accordingly, so that the top plate and the anti-slip pad move upward. While moving, the telescopic leg slides outward in the leg sleeve. After the machine is supported, the first positioning hole and the second positioning hole at the overlapping position of the leg sleeve and the telescopic leg are aligned, and then the pin is inserted into the first positioning hole and the second positioning hole to limit the leg sleeve and the telescopic leg, thereby completing the support. The device increases the supporting area by supporting the second base frame, the leg sleeve and the telescopic leg, can better support the machine, and achieves the purpose of improving the stability of the support.

[0016] 2. The support device for maintenance of mining machinery has the effect of being easy to use on uneven ground through the arrangement of the groove block, the bidirectional screw rod, the support rod and the telescopic block. When in use, when the machine stops at a position with uneven ground for maintenance, the support device is placed at the fulcrum. At this time, the support device needs to be leveled. During the leveling process, the staff uses an iron rod to rotate the second rotating block, and the bidirectional screw rod is driven to rotate through the second rotating block, so that the two sliders threadedly connected on the surface of the bidirectional screw rod move inward or outward synchronously. During the movement of the slider, the limit position on the upper surface of the slider The block slides in the limit groove, which plays a role of limiting. By making the two sliders move synchronously, the angles of the two support rods are changed at the same time, which in turn drives the telescopic block to move inside the groove block, thereby playing a role in adjusting the height of the fulcrum of the support device. According to the actual situation of the road surface, the four telescopic blocks are adjusted separately until the support device is in a horizontal state, and then the supporting operation is carried out. When the device faces an uneven road surface, there is no need to use pads for support. By adjusting the position of the telescopic block, the support device can be quickly placed in a horizontal state, thereby achieving the purpose of being easy to use in the mine.
