[0002] During the installation and construction of power transmission and transformation line equipment, the inspection and replacement of transformers are common in construction. Since heavy machinery and equipment cannot reach some areas, the equipment can only be transported by manpower. The traditional transportation method is: using a hand-cranked hoist to hoist the transformer, but the hand-cranked hoist can only hoist the equipment in the vertical direction. Later, the staff is required to move the equipment from the bottom of the mounting frame to the upper position of the mounting frame (installation position). This method is time-consuming, labor-intensive, and inefficient. In addition, during the transportation process, the transformer will collide with the tower, causing the transformer to be damaged, which not only increases the construction cost but also shortens the service life of the item. Summary of the invention

[0003] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide a 110 kV transmission line equipment installation and conveying device and construction method, which can quickly hoist the equipment above the installation frame and avoid the safety hazard of collision between the equipment and the installation frame.

The ends of the first extension rod and the second extension rod are respectively provided with end wire pulleys. A through hole is arranged at the bottom of the right end of the first extension rod, and an inserted rod is threadedly connected to the through hole. A first pull wire is arranged between the inserted rod and the ground.

[0006] The upper end of the first pull wire is fixedly connected to the insertion rod, and the lower end of the first pull wire is provided with a ring, and the ring is fixedly connected to the ground through a positioning rod, and the first pull wire is in a tensioned state.

[0007] Reinforcement rods are respectively arranged between the lower clamp and the first extension rod, and between the lower clamp and the second extension rod.

[0008] The winding assembly consists of a base frame, a winding frame and a motor. The base frame is provided with a winding frame, the rotating shaft of the winding frame is fixedly connected with the rotating shaft of the motor, and the winding frame is provided with a second pull wire.

[0009] The size of the buckle cover matches the size of the top of the pole.

[0010] The plunger is located at the rear of the end guide wheel.

[0011] The insertion rod is located at an outer position of the equipment mounting frame.

[0012] The construction method of installing a transmission device for a 110 kV power transmission line equipment comprises the following steps: S1. Install the buckle cover on the top of the wire pole, install the wire assembly above and below the equipment mounting frame, and adjust the direction of the end wire wheel and the top wire wheel; S2. According to the distance between the insertion rod and the ground, select the first pull wire of matching length, tie the first pull wire to the insertion rods on the two sets of wire assemblies, and use the positioning rod to fix the ring on the ground, so that the first pull wire is in a taut state; S3, adjusting the position of the first pull wire on the wire assembly below the equipment mounting frame so that the position of the first pull wire there is located inside the first pull wire in the wire assembly above; S4, placing the winding assembly on one side of the wire rod and fixing the winding assembly on the ground with a positioning rod, then pulling out the second pull wire on the winding frame and winding it around the end wire wheel on the left side of the wire assembly, the top wire wheel, and the end wire wheel on the right side of the wire assembly in sequence; S5. Fix the right end of the second pull wire to the equipment to be hoisted, start the motor, and slowly hoist the equipment to the equipment mounting frame.

[0013] The positive beneficial effects of the present invention are: 1. The present invention sets a first pull wire between the insertion rod and the ground, and the insertion rod is located behind the end wire wheel.
