[0009] The effect achieved by the above components is that during the rotation of the connecting plate, the protruding column fixed on the connecting plate will slide along the inner wall of the sliding hole, thereby achieving the effect of making the rotation process of the connecting plate more stable.

[0010] Preferably, a positioning plate is fixedly connected to one side of the connecting plate, a positioning rod is slidably penetrated through the side of the positioning plate, the cross section of the positioning rod is "L" shaped, and one end of the positioning rod is fixedly connected to the connecting rod.

[0011] The effect achieved by the above components is that when the connecting rod moves along the inner wall of the connecting plate, the positioning plate fixed on the connecting plate will move along the arc surface of the positioning rod, thereby avoiding rotational deviation during the movement of the connecting rod.

[0019] The effect achieved by the above components is that rotating the rotating block can drive the disc, thereby achieving the effect of facilitating the rotation of the disc.

[0020] Compared with the related art, the anchor rod and steel strand bearing tray provided by the utility model has the following beneficial effects:

[0021] The utility model provides a stress-bearing tray for anchor rods and steel strands. By arranging wave patterns on the upper surface of the tray, the wave patterns can be deformed when providing pre-tightening force, the wave-shaped contact surface is larger, and the tray is not easy to break when the pre-tightening force is applied, so as to detect the application of anchor cable pre-tightening force to judge whether the anchor cable pre-tightening force meets the standard. The anchor cable pre-tightening force detection device can conveniently, quickly and comprehensively detect the application of anchor cable pre-tightening force, which can ensure that workers can timely find out whether the anchor cable pre-tightening force meets the standard when constructing the anchor cable, which is convenient for workers to construct, and it is also beneficial for technical personnel to quickly check whether the anchor cable pre-tightening force meets the standard.

[0022] After the pallet body is subjected to force, the connecting rod will move along the inner wall of the connecting plate, and the connecting plate will rotate along the inner wall of the fixing seat. During the movement of the connecting rod along the inner wall of the connecting plate, the positioning plate fixed on the connecting plate will move along the arc surface of the positioning rod, thereby avoiding rotational deviation during the movement of the connecting rod. The rubber pad can increase the friction force at one end of the pressure rod, thereby achieving the effect that the pressure rod can be squeezed and stabilized with the connecting rod with the help of the rubber pad. During the rotation of the connecting plate, the boss fixed on the connecting plate will slide along the inner wall of the sliding hole, thereby achieving the effect of making the rotation process of the connecting plate more stable. By setting up the adjustment structure, during the process of constructing the anchor cable to detect whether the pre-tightening force of the anchor cable meets the standard, the connecting plate and the connecting rod can support and strengthen the overall structure of the pallet body, thereby minimizing the breakage of the pallet body caused by excessive force.

[0023] When the pallet body needs to be fixed firmly on the arc surface of the anchor rod, the disc is manually rotated with the help of a turn block, and the disc drives the screw rod to rotate, and the screw rod drives the arc plate, so that the arc plate moves in the direction of the anchor rod under the limitation of the guide rod, until the arc plate drives the protrusion to abut the arc surface of the anchor rod, and the pallet body can be limited. The protrusion can make the inner wall of the arc plate uneven, thereby increasing the stress points between the arc plate and the anchor rod, thereby improving the limiting effect of the arc plate on the anchor rod. By setting an auxiliary structure, when the force-bearing pallet body is used, the anchor rod and the pallet body can be firmly connected with the arc plate. BRIEF DESCRIPTION OF THE DRAWINGS
