The pulley fixing mechanism of the pulley and the inch foot hoop;

As shown in Figure 1, the Cunjiao hoop includes a semicircular hoop piece I 4 and a hoop piece II 5, which form a hoop structure after they are connected relative to each other. The hoop piece I 4 and the hoop piece II 5 are in the At least one hanging foot is provided on the surface of the opposite side during connection; in this embodiment, one hanging foot 6 is respectively provided, and the function of the hanging foot is to facilitate the fixing of the upper end of the hoisting frame on the pole.

As shown in Figure 2, there are two hoisting frames on the pole, and each hoisting frame on the pole is a fork-shaped structure. The independent ends of each are provided with hooks for connecting with the fixing holes on the same cross arm. the

As a further improvement, as shown in Figure 3, the fixed screw mechanism includes an eccentric screw 8 and an eccentric wheel handle 9, one end of the eccentric screw is provided with an eccentric hole, and the eccentric wheel handle is connected to the eccentric hole through a detachable connector 10 Connection, by rotating the handle, the fastening and loosening of the eccentric screw can be realized. The advantage of adopting this structure is that compared with ordinary bolts, installation and disassembly need to be carried out with a wrench, which is laborious and inconvenient, but by using the eccentric screw and eccentric wheel handle, it does not require too much force, so it can be Access to the screw allows for free disassembly without the aid of tools. the

As a further improvement, as shown in Figure 4, the pulley fixing mechanism is a block structure with upper and lower fixing holes, wherein the upper fixing hole is used to penetrate the eccentric screw of the fixing screw mechanism, so that the pulley fixing mechanism is located between the two arms. Between the connecting parts of the hoops, and the fixing holes below are used to hang the tackle. the

The using method of the present utility model comprises the following steps:

Step 1: Determine the installation position of the inch-foot hoop on the base tower, which should be above the installation position of the double-fan cross-arm;

Step 2: Install hoop piece I and hoop piece II on the base pole tower, and connect them relatively through the fixed screw mechanism to complete the installation of the inch foot hoop, and install one end of the pulley fixing mechanism on the inch foot hoop ;

Step 3: Fix the trolley, first hoist one of the cross-arms of the double-fan cross-arm to the installation position through the trolley, hang the reserved holes on the cross-arm respectively through a hoisting bracket on the pole, and then pass the upper end of the hoisting bracket on the pole The hanging ring structure is connected with the hanging foot on one side of the Cunjiao hoop to realize temporary fixation of the cross arm; in the same way, the other cross arm is also hoisted to the installation position to realize temporary fixation; as shown in Figure 5.
