Description

Multifunctional rotating pole

technical field

The invention relates to a hoisting device used when erecting an iron tower, in particular to a rotating holding pole.

Background technique

In the construction of transmission lines, high-voltage iron towers need to be erected. The high-voltage iron towers are generally four sets of square-shaped iron towers with a truss structure assembled from several steel rods as tower materials. When erecting a high-voltage iron tower, first build the foundation and tower foot on the ground, and then gradually build up the tower material components.

When the high-voltage iron tower is erected to a certain height, in order to safely transport each component to the erected height, it is necessary to use lifting tools to lift the tower material of the high-voltage iron tower. However, due to the distance between the four sets of truss structures of the high-voltage iron tower, and the general terrain of the place where the high-voltage iron tower is erected is generally complex, limited by the lifting height and the conditions of the construction site, it is difficult for ordinary cranes to meet the requirements. The rocker arm holding pole cooperates with the winch, pulley block and steel wire rope to lift the tower material.

The rocker arm includes a main rod, a rocker arm and a bracket for fixing the main rod and the rocker arm. The bracket is fixedly arranged on the center ground of the high-voltage iron tower, the bottom of the main rod is fixed at the center position of the top surface of the bracket, and the rocker arm is hinged on one side of the main rod on the top surface of the bracket. The top of the main rod is sleeved with a rotating cap, which is fixedly connected to the ground through a pull wire to maintain the overall force balance of the main rod and the rocker arm. Two guide pulleys are arranged on the outer end surface of the rotating hood, and the steel wire rope pulled by the hoist placed on the ground is first wound on one of the guide pulleys, and crosses the corresponding other guide pulley to connect with the rocker arm. The top of the rocker arm is sleeved with a cover cap, and a load-bearing pulley and a lifting pulley are arranged on the cover cap, wherein the load-bearing pulley corresponds to the guide pulley on the main pole, and is wrapped around the wire rope drawn by the guide pulley on the main pole to the rocker arm; the lifting pulley The steel wire rope wound on the top is connected with the component, and the other end of the steel wire rope lifts the tower material through the traction of the hoist. When installing the rocker arm pole before use, first fix the main pole vertically at the center of the iron tower, and then lift the tower material hoisted on the top of the rocker arm to the required height through the drive of the hoist and the traction effect of the wire rope. When it is necessary to adjust the height of the rocker arm, by controlling the retraction and release of the wire rope wound on the guide pulley of the main rod, the hinge point at the bottom of the rocker arm is the center of rotation, and the length of the rocker arm is the radius for adjustment. During the hoisting operation of the rocker arm, the tower material to be lifted is generally directly below the rocker arm, and cannot be displaced horizontally. If horizontal rotation displacement is required, the main rod, rocker arm and bracket must be Re-disassembly and overall adjustment of the main rod and rocker arm rotation are cumbersome and require a lot of wasted manpower. Due to the heavy weight of the rocker arm, it is also easy to cause danger.

Contents of the invention

The multifunctional rotating pole includes a main pole with a guide pulley on the top, a rocker arm with a load-bearing pulley and a lifting pulley on the top, and a base with a rotating column vertically arranged in the center, and several rollers are evenly distributed around the rotating column on the base. , the top of the base is provided with a rotating seat that is sleeved on the rotating column and in contact with the rollers. The position of the rotating seat corresponding to the rotating column is fixed with a connecting cover, and the bottom of the main rod is hinged on the upper part of the connecting cover. The arm is hinged on the side wall or swivel seat of the connecting cover.

The further improvement of the present invention is that: two sets of winding shafts and a fixed pulley are also fixedly arranged on the rotating seat.

The further improvement of the present invention is that: the connecting cover includes a connecting plate I fixed above the rotating column through several supporting plates, a four-way seat is fixedly arranged on the connecting plate I, the main rod is hinged on the top of the four-way seat, and the rocker arm is hinged On the side wall of the four-way seat or on the swivel seat.

It is not restricted by the terrain when used, and has a wide range of applications. The tower material can be hoisted conveniently and quickly by using the invention, the hoisting operation is simple, a large amount of manpower and material resources are saved, and the engineering cost is reduced.

The four-way seat fixed on the connecting plate connects the main rod and the rocker arm as a whole, which reduces the shaking during rotation, saves time and effort, and eliminates potential safety hazards. The flat base fixed on the four-way seat is hinged with the lower connecting seat of the fixed main rod, which acts as a buffer for the main rod when rotating. When the rotating seat cannot be set horizontally due to the limitation of the installation position, it can ensure that the main rod can still Keep upright and keep the center of gravity stable during hoisting operation to ensure the safety of equipment and personnel.

Use the working principle of the present invention to be:

After the multifunctional rotating pole is assembled, it includes two sets of wire rope retractable systems. A retractable system is used to fix the main pole 9 and connect the main pole 9 and the rocker arm 10 . Another retractable system is used to control the lifting tower material.

The direction of the wire rope I used to fix the main pole 9 and connect the main pole 9 and the rocker arm 10 is as follows: a hoist is connected to the rope winding shaft I11, and the steel wire rope I on the rope winding shaft I11 is passed through the rotating cover at the top of the main pole 9 On the guide pulley 8-3 on one side of the cap 8, after bypassing the wheel groove of the guide pulley 8-3 on the other side of the rotating cover cap 8, fit the lifting handle on the side wall of the cover cap 7 around the top of the rocker arm 10. Pulley wheel groove, wire rope I terminal is fixed on the lug I 8-4 of rotating cover cap 8.

The direction of the wire rope II used to control the hoisting tower material is as follows: a hoist is connected to the rope winding shaft II12, and the wire rope II on the rope winding shaft II12 is first wound into the wheel groove of the fixed pulley 2-5 fixed on the rotating seat 2 , and then pull the wire rope II around to the hoisting pulley on the other side wall of the cover cap 7, and the terminal of the wire rope II is connected with the tower material.

When hoisting the tower material at the same horizontal position, the hoisting operation can be carried out by controlling the retraction and retraction of the wire rope II by the hoist. When it is necessary to adjust the horizontal height of the rocker arm, start the winch, and change the horizontal position of the rocker arm 10 by retracting and releasing the steel wire rope 1. If the angle needs to be adjusted, since the rotating base 2 is in rolling contact with the base 1, the roller 1-2 on the base 1 rotates, and the rotating base 2 can rotate around the center of the rotating disk 2-2. At the top of the main rod 9, since the axle sleeve on the rotating cover cap 8 is connected with the rotating shaft through a bearing, it can also rotate freely. Therefore, when the rotating base 2 is pushed, the direction of the rocking arm 10 changes accordingly.
