Clamping oil cylinders 6 are hingedly installed in the inner chambers at both ends of the bracket respectively. The two clamping oil cylinders act synchronously and have the same stroke. The middle part of the rod is hingedly connected, and the installation end of the swing rod is hingedly connected with the support through a rotating shaft, so that when the piston rod of the clamping cylinder is extended or retracted, the swing rod can be driven to swing around its own hinge point. A clamping block 62 is hingedly installed on the free end of each swinging rod through a rotating shaft, and a torsion spring is arranged on the rotating shaft connecting the clamping block and the swinging rod. The side on which it is located is sloped. The acting end of the clamping block is arc-shaped, and a rubber pad is arranged on the acting end of the clamping block to prevent the cement rod from being damaged by the clamping block when the swinging rod shakes the cement rod. A pressure sensor is provided at the acting end of the clamping block to sense the pressure between the clamping block and the cement rod. The pressure sensor is connected with the signal of the controller on the bracket, and the controller is connected with the signal of the solenoid valve of the clamping oil cylinder. As shown in Figure 3, after the piston rod of the clamping cylinder is stretched out, the swing rod swings and drives the clamping block closer to the cement rod, and the clamping block gradually contacts with the cement rod and generates a positive pressure between the two. When the pressure value between reaches the set value, the clamping cylinder will stop acting. At this time, the cement rod is placed between the two clamping blocks and the bracket, but the cement rod can slide relative to the clamping block and the bracket, and the sliding direction is the axial direction of the cement rod.

In order to drive the movement of the cement rod in the clamping assembly, a delivery cylinder 5 is fixedly installed in the inner cavity at both ends of the bracket, and a second hydraulic motor and a reduction box 51 are fixed at the free end of the piston rod of the delivery cylinder.

The second hydraulic motor and the reduction box are driven by the delivery cylinder 5 on the bracket. Slide on the top to realize the mutual approach or distance of the two conveying wheels. When the two conveying wheels clamp the cement pole, the second hydraulic motor acts to output the rotary motion, which is transmitted to the conveying wheel after being decelerated by the reduction box. When the two conveying wheels clamp the cement pole, the two conveying wheels rotate around their own axes. And the rotation directions of the two conveying wheels are opposite. When the two conveying wheels rotate, the cement rod is moved downward. The clamping block and the conveying wheel are at different height positions, so that the setting of the clamping block can reduce the inclination angle of the cement rod, so that the cement rod is in a vertical state as far as possible.

When the present invention is working, it first drives the lifting cylinder to retract, as shown in Figure 5, so that the free end of the lifting arm faces downward, and drives the swing cylinder to extend, so that the clamping cavity of the bracket faces downward and is placed on the cement rod Up; drive the swing cylinder to move, so that the clamping block at the free end of the swing rod gradually approaches the cement rod until the clamping block lifts the cement rod, and the clamping block and the bracket clamp the cement rod. As shown in Figure 6, the piston rod of the lifting cylinder is driven to extend, so that the lifting arm lifts the support. As shown in Figure 7, the first hydraulic motor is driven to rotate to drive the bracket to rotate until the cement rod is in a vertical state. Then the second hydraulic motor is driven to make the delivery wheel rotate, and the delivery wheel and the cement rod roll relative to each other to realize the release of the cement rod, and the cement rod moves downward in the vertical direction to insert the cement rod into the foundation 8 in the pre-dug fixing holes. After the staff has supported the cement pole, the soil on the ground can be pushed into the fixing hole by the bulldozer blade, so as to realize the fixing of the cement pole. In this way, the cement pole lying flat on the ground is erected and placed in the hole on the foundation. This action is completed by the clamping assembly, the conveying assembly, the rotating assembly, the lifting cylinder and the swinging cylinder. The actions are successively connected with each other, which improves the work efficiency when the cement pole is erected. The whole work is completed by the equipment, which reduces the physical labor of people.
