Although this patent solves the above problem, there is still the problem of inconvenient operation, so a belt clamping device for coal mine belt conveyor is proposed to solve the above problem. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a belt clamping device for a coal mine belt conveyor in view of the deficiencies in the above-mentioned prior art.

When the lifting block and the sliding cam are lifted up, the lifting block can be easily moved, and the lifting block can be easily moved.

[0006] The top end of the lifting link rod is fixedly connected with the lifting link rod, and the bottom end of the lifting link rod is fixedly connected with the L-shaped baffle plate, the bottom end of the lifting link rod is fixedly connected with the L-shaped baffle plate, the bottom end of the lifting link rod is fixedly connected with the L-shaped baffle plate, the inner surface of the lifting link rod is slidably connected with the transmission slider, the transmission slider is slidably connected to the inner wall of the telescopic slide rod, the L-shaped baffle plate is slidably connected to the inner wall of the telescopic slide rod, the When the electric telescopic rod is started, the telescopic sleeve rod is driven to slide forward and backward on the slide rail by the translation slide, and the telescopic sleeve rod drives the telescopic slide rod to move forward and backward. When the translation slide stops and the socket is aligned with the positioning hole one, the positioning screw is rotated, and the positioning screw is threadedly connected with the positioning shaft and rotated downward and inserted into the positioning hole one and the socket, thereby locking the translation slide bar and the slide rail, pulling the telescopic slide bar, and making the telescopic slide bar slide up and down in the telescopic sleeve rod, thereby changing the height of the clamping device. When the height adjustment of the telescopic slide bar is completed, the electric telescopic rod is started, and the electric telescopic rod drives the lifting slide bar to rise, and the lifting slide bar drives the lifting connecting rod to rise, and the lifting connecting rod drives the L-shaped baffle plate to rise. After the L-shaped baffle plate rises, the card shaft one loses its resistance, and then it pops out from the inside of the telescopic sleeve shaft one to the outside through the elastic force of the spring one and is inserted into the positioning hole two to lock the telescopic slide bar and the telescopic sleeve rod.

When the inclined surface of the trapezoidal positioning block contacts the arc surface of the clamping shaft 2, the clamping shaft 2 is pushed to slide and shrink into the telescopic sleeve shaft 2 through the guidance of the inclined surface. When the slot hole on the trapezoidal positioning block is aligned with the clamping shaft 2, the clamping shaft 2 is affected by the elastic force of the spring 2 and pops out of the telescopic sleeve shaft 2 and is inserted into the trapezoidal positioning block, thereby locking the supporting structures such as the lifting slide block and the toggle connecting rod.

[0010] 3. The belt clamping device for the coal mine belt conveyor has a telescopic slide rod that slides up and down in the telescopic sleeve rod, thereby changing the height of the clamping device, and then clamping conveyor belts of different heights, further improving the applicability of the device. The clamping shaft 1 pops out from the inside of the telescopic sleeve shaft 1 to the outside through the elastic force of the spring 1 and is inserted into the positioning hole 2 to lock the telescopic slide rod and the telescopic sleeve rod, further improving the stability of the device after adjustment.

[0011] 4. The belt clamping device for the coal mine belt conveyor rotates the first adjusting block and the second adjusting block, thereby driving the upper clamping plate and the lower clamping plate to fit the outer surface and the inner surface of the conveyor belt, thereby increasing the clamping area of ​​the device. The compression nut squeezes the upper clamping arm and the lower clamping arm, making the first adjusting block and the second adjusting block unable to rotate, preventing the upper clamping plate and the lower clamping plate from loosening and increasing the clamping strength.

[0012] 5. In the belt clamping device for the coal mine belt conveyor, the clamping shaft 2 is affected by the elastic force of the spring 2 to pop out the telescopic sleeve shaft 2 and insert it into the trapezoidal positioning block, thereby locking the supporting structures such as the lifting slider and the toggle connecting rod, thereby improving the supporting stability and further improving the clamping strength of the upper clamping arm.
