Description

Movable insulating support pole

technical field

The utility model relates to a device for connecting or supporting a low-voltage line, in particular to a movable insulating support pole.

Background technique

In the early days, all kinds of electric poles started from wooden poles, even including high-voltage electric poles whose voltage level was not too high. Later, due to the development of steel bars and concrete, combined with technical exploration, and using the principle of centrifugal force to manufacture, reinforced concrete conical cement poles and equal-diameter cement poles replaced most of the wooden poles. The cement poles are durable, corrosion-resistant, and temperature-resistant. , high strength, crack resistance. However, piling is required to fix it to the ground. On the one hand, it will destroy the original topography. On the other hand, it is necessary to wear heavy anti-skid shoes during maintenance, which poses a relatively high personal risk. In addition, because the cables at the upper end of the cement poles require a lot of tension to straighten the cables, and it is difficult to guarantee the firmness of the cement poles after they are driven into the ground. The bolt increases the land use area. When someone needs to go up for maintenance, the center of gravity of the pole will be shifted when the person climbs to the top of the pole. If it is not fixed firmly, it is easy to cause personal injury.

At present, the top of the pole is equipped with a fixed cross arm, the cross arm is equipped with an insulator, and the upper end of the pole is also equipped with a stay wire to ensure that the pole is in balance when subjected to external force. The line output on the pole can be divided into L-shape, straight-line, cross-shape, etc., which requires the pole to have good multi-directional bearing capacity and flexible adjustment. Usually some utility poles need to be moved, and traditional utility poles are difficult to move and easily cause damage.

Utility model content

In order to solve the deficiencies in the above-mentioned technologies, the purpose of this utility model is to provide a movable insulating support pole, which is convenient to move, safe and environmentally friendly, reduces the difficulty of construction, does not destroy the original landform of the installation position, and effectively improves the firmness of the pole. sex.

For solving its technical problem, the technical scheme that the utility model takes is:

The movable insulating support pole includes a screw pile base, a chassis is fixed on the top of the screw pile base, the chassis is fixedly connected to the pole, and a cross arm is arranged on the upper part of the pole. The cross arm includes a high-voltage cross-arm and a low-voltage cross-arm. Set above the low-pressure cross-arm, there is a balance bar between the high-pressure cross-arm and the low-pressure cross-arm, and support rods are symmetrically arranged on both sides of the high-pressure cross-arm, balance bar and low-pressure cross-arm, and the two support rods are fixed by ring hoops On the line pole, the two ends of the balance bar are connected with the stay wire, the middle position of the stay wire is provided with tension insulators and turnbuckle bolts, the tail of the stay wire is provided with a pulley reel, and the pulley reel is fixed underground. Through the pulley, one end of the steel wire extends out of the pole and connects to the ring-shaped counterweight, and the other end extends to the middle and lower part of the pole through the pulley, and the middle and lower part of the pole is equipped with a hand crank corresponding to the steel wire.

The utility model adopts a screw pile base. When installing, only the screw pile base needs to be driven into the ground, which has no effect on the original landform of the installation location. The high-voltage cross-arm and low-voltage cross-arm set above can be connected to the cable through insulators, and the fixed direction of the two can be adjusted arbitrarily through the ring hoop to ensure that the tension of the cable exerts the least force on the pole, and the balance bar can be adjusted according to the alignment of the cable The force direction of the pole is adjusted to ensure that the force exerted by the pull wire on the pole can exactly offset the force exerted by the tensioned cable on the pole. There are tension insulators and turnbuckle bolts in the middle of the pull wire, and the turnbuckle bolts can be adjusted according to the tension. Corresponding tightness adjustment, there is a cable reel at the end of the cable, and the cable reel is placed underground to fix it, which can effectively prevent the cable from being pulled out. If you need to move it, you only need to separate the screw pile base from the wire rod, and then use a pile rotary machine to rotate the screw pile base. It can be done without destroying the original landform and causing damage to the utility pole.

The top of the wire rod is closed, the pulley is fixed, and a steel wire is passed through the pulley. When the maintenance personnel need to climb up the wire rod for maintenance or operation, they can use the hand crank to put down the end of the steel wire with the ring weight, and then put the ring weight The weight is connected with the safety device worn by the maintenance personnel. Shaking the hand crank can easily send the maintenance personnel to the designated position of the line pole. Inside the hand crank is a reel for storing excess steel wire, because the hand crank is fixed on the line pole. The pulley is at the top of the wire rod. After the maintenance personnel ascend, all the gravity of the human body acts on the wire rod, and it is vertically downward, so that no inclined plane stress will be caused to the wire rod. For the wire rod, the force in the up and down direction does not need to be used. The external force is balanced, so it is safer and more reliable. In order to prevent the steel wire from rebounding after the maintenance personnel ascend, a hand crank with a self-locking component is selected. This kind of hand crank is a product currently on the market, and its specific structure will not be repeated here.

Among them, the preferred scheme is:

The pulley is 10-30 centimeters away from the top of the wire pole to ensure that maintenance personnel can reach the top of the wire pole through the pulley for maintenance.

The two ends of the balance bar are provided with pull buckles, and the pull buckles are connected with the pull wires. The pull buckle and the balance bar can be arranged as an integrated structure, and one end of the pull wires is fixed through the pull buckles.

The hand crank is 1-1.5 meters away from the bottom of the line pole, and the height is moderate, which is suitable for maintenance personnel to operate the hand crank while standing on the ground.

The diameter of the chassis is 1.4-1.8 times the diameter of the top surface of the screw pile base. There are multiple connection holes on the chassis, generally 8-12, which are used for the connection between the wire rod and the screw pile base, and the bottom surface of the wire rod and the screw pile. The chassis on the top surface of the base is correspondingly provided with a chassis and connecting holes, and the wire rod and the screw pile base are fixed together through the connecting holes with screw washers and nuts.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model is convenient to move, safe and environment-friendly, reduces construction difficulty, does not destroy the original landform of the installation position, and effectively improves the firmness of the wire pole. During installation, only the base of the screw pile needs to be driven into the ground, which has no effect on the original landform of the installation location. There is a chassis above the base of the screw pile, and the pole is fixed on the base of the screw pile through the chassis. The fixing direction of the hoop can be adjusted arbitrarily to ensure that the force of the tensioned cable on the pole is minimal. The balance bar can be adjusted according to the direction of the force of the cable on the pole to ensure that the force of the cable on the pole can be as tight The force exerted by the cable on the pole is exactly offset. If you need to move, you only need to separate the chassis of the screw pile from the pole, and then use a pile screwdriver to unscrew the base of the screw pile. The pole causes damage; the top of the pole is closed, the pulley is fixed, and the steel wire and the hand crank are used to realize the lifting of the maintenance personnel on the pole. During the lifting process, no inclined plane stress will be caused to the pole, and the pole does not need to use external force to maintain the vertical direction.
