Description

Pole hoisting transport device

technical field

The utility model belongs to the technical field of the electric power industry, in particular to an electric pole hoisting transportation device. the

Background technique

At present, when the pole is transported, the pole is usually lifted by a tripod and a chain block, and then the pole is placed between the front beam and the pole clip on the rear beam of the pole transport vehicle, and then the four-wheel tractor pulls the pole. It is not only labor-intensive, but also low work efficiency. the

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a pole hoisting and transporting device with simple structure, low labor intensity and high work efficiency. the

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the pole hoisting transport device includes a four-wheel tractor with a hydraulic drive system, and the rear upper part of the four-wheel tractor is provided with a gantry frame and a fixed frame, and the fixed frame is low. On the gantry frame and located behind the gantry frame, the beam of the gantry frame is rotatably connected with a casing, the casing is vertically connected with a boom extending backward, and a hydraulic cylinder tilting toward the rear and upward is fixed on the fixed frame, and the piston of the hydraulic cylinder The upper end of the rod is connected with a channel steel with an open top through a hinge, the front middle part of the suspender is slidingly connected in the groove of the channel steel, and the lower part of the rear end of the suspender is provided with a hook. the

A reinforcing bar is provided between the front part of the four-wheel tractor and the upper end of the gantry frame, and a traction frame is provided at the lower part of the rear side of the four-wheel tractor. the

The front part of the suspender is provided with a limit post located in front of the channel steel. the

The upper side of the rear part of the boom is provided with a fixed column for hanging a suspension rope. the

With the above technical solution, when hoisting the pole, use a hoop to clamp and fix one end of the pole, and the hoop is hung on the hook at the rear end of the boom through a sling to operate the hydraulic drive system on the four-wheel tractor. The piston rod extends upwards and pushes against the channel steel. Since the inclination angle of the hydraulic cylinder is fixed, the boom slides along the groove of the channel steel and rotates upward around the beam of the gantry frame, so that one end of the pole is lifted, and then transported Push the car under the electric pole, and then operate the hydraulic drive system on the four-wheel tractor to retract the piston rod of the hydraulic cylinder, then place the electric pole on the transport vehicle, and finally pass the hoop fixed on the electric pole through the rope and the snap ring It is fixedly connected to the traction frame, and the transport vehicle can be transported by turning on the four-wheel tractor to pull the transport vehicle. After transporting to the destination, untie the rope and hoop on the traction frame, and repeat the above actions to place the pole on the ground. the

The reinforcing rod plays the role of enhancing the strength of the gantry frame, and the limit post plays the role of limiting the position of the channel steel, that is, limiting the retraction amount of the piston rod of the hydraulic cylinder. The anchor post on the boom provides another way to hang the rope so that it does not come unhooked compared to the hook. the

The utility model can be improved on the existing four-wheel tractor, effectively improves the lifting speed and efficiency of the electric pole, ensures labor-saving and cost-saving transportation of the electric pole, shortens the transportation time of the electric pole, and ensures The poles are quickly and safely transported to the construction site on the road, which provides a guarantee for speeding up the power grid transformation process. the
