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.

[0022] like Figures 1 to 5As shown, the utility model provides an auxiliary installation mechanism for a coal mine hydraulic support, comprising a base plate 1, a mounting plate 4 fixedly connected to the upper side of the middle portion of the inner surface of the base plate 1, hollow blocks 2 movably connected to the left and right sides of the bottom of the inner surface of the base plate 1, two hollow blocks 2, the front sides of the upper surfaces of the two hollow blocks 2 are movably connected to a second clamping block 11, the middle portions of the upper surfaces of the two hollow blocks 2 are movably connected to a support hydraulic cylinder 5, the rear sides of the upper surfaces of the two hollow blocks 2 are movably connected to a first clamping block 3, and the bottom ends of the first clamping block 3 and the second clamping block 11 both penetrate the hollow blocks. 2 and extends to the interior of the hollow block 2. The outer surfaces of the No. 1 clamping block 3 and the No. 2 clamping block 11 are movably connected to the inner surface of the hollow block 2. The No. 1 motor 7 is fixedly installed on the upper surface of the mounting plate 4. The bottom end of the No. 1 motor 7 passes through the mounting plate 4 and extends to the bottom of the mounting plate 4. The other end of the output shaft of the No. 1 motor 7 is fixedly sleeved with a round shaft 8. The outer surface of the round shaft 8 is fixedly sleeved with an active rod 9. Both ends of the active rod 9 are hinged with a driven rod 10. There are two driven rods 10. The other ends of the two driven rods 10 are respectively hinged to the outer surfaces of the two hollow blocks 2.

[0023] When the operator starts the No. 1 motor 7, the circular shaft 8 and the active rod 9 will start to rotate. At this time, the driven rod 10 will be driven by the rotation of the active rod 9 and start to rotate. At the same time, the other end of the driven rod 10 will drive the hollow block 2, causing the two hollow blocks 2 to start to move.

[0024] Among them, the front and rear sides of the left end of the inner surface of the base plate 1 are fixedly connected to the limiting rod 12, the right end of the limiting rod 12 passes through the hollow block 2 and extends to the right end of the inner surface of the base plate 1 and is fixedly connected to the base plate 1, and the outer surface of the limiting rod 12 and the inner surface of the hollow block 2 are movably connected.

[0025] The design of the limiting rod 12 limits the overall movement of the two hollow blocks 2.

[0026] The middle of the top surface of the inner cavity of the two hollow blocks 2 is fixedly connected with a fixed shaft 13, and the outer surface of the fixed shaft 13 is movably sleeved with a driving rod 14.

[0027] The design of the fixed shaft 13 enables the driving rod 14 to rotate around the fixed shaft 13 as the axis.

[0028] The outer surface of the second clamping block 11 is fixedly connected to the side plate 15 located inside the hollow block 2 , and the bottom end of the outer surface of the side plate 15 is movably connected to the inner surface of the front side of the driving rod 14 .

[0029] The design of the side plate 15 enables the side plate 15 to drive the driving rod 14 when the second clamping block 11 as a whole moves, and causes the driving rod 14 to rotate around the fixed shaft 13 as the axis.

[0030] Among them, the outer surface of the No. 1 clamping block 3 is fixedly connected to the cylinder 16 located inside the hollow block 2, and the bottom end of the outer surface of the cylinder 16 is movably connected to the inner surface of the rear side of the driving rod 14.

[0031] When the driving rod 14 starts to rotate, the inner surface of the driving rod 14 drives the cylinder 16 , causing the first clamping block 3 and the cylinder 16 to start moving.

[0032] Among them, the tops of the inner cavities of the two hollow blocks 2 are fixedly connected with fixed plates 17 located on the front and rear sides of the No. 2 clamping block 11, and the front surface of the fixed plate 17 is fixedly installed with the No. 2 motor 18 located inside the hollow block 2. The other end of the output shaft of the No. 2 motor 18 is fixedly sleeved with a threaded rod 19. The rear end of the threaded rod 19 passes through the fixed plate 17 and the No. 2 clamping block 11 in sequence and extends to the rear surface of the fixed plate 17. The outer surface of the threaded rod 19 is threadedly sleeved with the inner surface of the No. 2 clamping block 11.

[0033] When the second motor 18 is running, the threaded rod 19 will start to rotate. At this time, the second clamping block 11 as a whole will move toward the fixed shaft 13 driven by the threaded rod 19 .

[0034] The top end of the support hydraulic cylinder 5 is fixedly connected to a support top plate 6 , and the shape of the support top plate 6 is square.

[0035] When the support hydraulic cylinder 5 operates, the support top plate 6 starts to move upward.

[0036] The working principle and use process of this utility model:

[0037] First, the operator starts the No. 1 motor 7. As the No. 1 motor 7 runs, the circular shaft 8 and the active rod 9 will start to rotate. At the same time, the two driven rods 10 will rotate with the two ends of the active rod 9 as the axis, and the two hollow blocks 2 as a whole will be driven by the other ends of the two driven rods 10 and start to move toward and away from each other under the limit of the limit rod 12 until the distance between the two No. 1 clamping blocks 3 is equal to the distance between the two support hydraulic cylinders 5.

[0038] Then the operator places both support hydraulic cylinders 5 between the No. 1 clamping block 3 and the No. 2 clamping block 11 and starts the No. 2 motor 18. As the No. 2 motor 18 runs, the threaded rod 19 will start to rotate. At this time, the No. 2 clamping block 11 and the side plate 15 will move toward the fixed axis 13 driven by the threaded rod 19, and the movement of the side plate 15 will cause the driving rod 14 to start rotating with the fixed axis 13 as the axis. At the same time, the inner surface of the rear side of the driving rod 14 will drive the cylinder 16, causing the cylinder 16 and the No. 1 clamping block 3 to start moving toward the fixed axis 13. Finally, as the No. 1 clamping block 3 and the No. 2 clamping block 11 move toward each other, the No. 1 clamping block 3 and the No. 2 clamping block 11 will clamp the outer surface of the support hydraulic cylinder 5 to keep the support hydraulic cylinder 5 stable, thereby facilitating the operator to carry out subsequent installation work.
