In the figure: clamping rod 1, eccentric wheel 2, first pin shaft 3, plate 4, traction rope 5, connection block 6, guide block 7, hoisting block 8, guide rod 9, limit block 10, hoisting ring 11, The second pin shaft 12, the groove 13, the pin hole 14, and the anti-skid layer 15.

Detailed ways

As shown in Figure 1-2, a symmetrical sheet clamper device with an eccentric wheel includes a clamping rod 1 and a connecting block 6. There are two clamping rods 1, and one end of the two clamping rods 1 passes through the first Two pin shafts 12 are movably connected on the connecting block 6, and the other ends of the two clamping rods 1 are provided with eccentric wheels 2, and the eccentric wheels 2 are connected with the clamping rods 1 through the first pin shaft 3.

In a preferred solution, the connecting block 6 is provided with a trapezoidal groove 13, the lower bottom of the trapezoid is the opening surface of the groove 13, and the groove 13 is set downward, and the groove 13 is provided with a second pin 12 through the pin hole 14. With the above-mentioned structure, the rotation angle of the clamping rod 1 is limited by the trapezoidal groove 13 , so as to avoid the situation that the angle between the two clamping rods 1 is too large to clamp the plate 4 .

In the preferred scheme, the top of the connecting block 6 is provided with a guide rod 9, the outer wall of the guide rod 9 is sleeved with a hoisting block 8, the top of the hoisting block 8 is provided with a hoisting ring 11, and the bottom surface of the hoisting block 8 is provided with a traction rope 5 One end of the traction rope 5 is connected to the bottom surface of the hoisting block 8, and the other end is connected to the end of the clamping rod 1 provided with the eccentric wheel 2. With the above structure, when the weight of the hoisting board 4 is greater, the clamping force given by the two eccentric wheels 2 is greater, which ensures the hoisting stability of the heavy weight board 4 .

In a preferred solution, the two sides of the connection block 6 are provided with vertical through holes on the guide block 7 , and the traction rope 5 passes through the through holes provided in the guide block 7 . By adopting the above structure, the guiding of the traction rope 5 is realized, and the stress of the system is optimized.

In a preferred solution, a limit block 10 is provided at the top of the guide rod 9 . The set limit block 10 avoids slipping of the guide rod 9 and the lifting block 8 .

In a preferred solution, an anti-slip layer 15 is provided on the outer wall of the eccentric wheel 2 .

The working principle of this device is as follows:

Set the two eccentric wheels 2 on both sides of the plate 4 to be hoisted respectively, and then use the hoisting equipment to lift slowly. Due to the weight of the plate, when the hoisting block 8 is rising, the plate 4, the eccentric wheel 2, the clamping rod 1, The connecting block 6 and the guide bar 9 are in a connected state, so they will not move up. At this time, the hoisting block 8, the guide bar 9, and the connecting block 6 are relatively displaced, and the end of the traction rope 5 connected to the hoisting block 8 rises, driving the other end. One end of the clamping rod 1 rises, and the angle between the two clamping rods 1 increases. When it increases to a certain extent, it cannot continue to increase due to the limitation of the groove 13. At this time, the eccentric wheel 2 has exerted a large force on the plate 4. Clamping force, and continuous lifting makes relative displacement no longer occur in the whole system, and the device drives the plate 4 to rise together for hoisting operation.
