CN223562593U - A pole-holding device for erecting cement utility poles - Google Patents

Abstract

A pole erection device for cement utility poles is characterized by comprising a flange, legs, a fixed pulley, and a manual winch. Three hinged ears are evenly welded to the bottom surface of the flange, arranged in a circular array around the center of the flange at 120° angles. A hook is positioned at the center of the flange bottom surface to suspend a fixed pulley. The top of each leg is hinged to one of the hinged ears. The leg is divided into two sections, with a limiting ring welded internally at the connection point, and the two sections are connected externally using bolted clamps. The manual winch is fixed to the lower part of either leg and includes a gear set and a locking mechanism. This device effectively solves the problem of installing cement utility poles on hillsides or farmland where truck cranes cannot be used during field power line construction.

Description

Handle device for cement pole upright

Technical Field

The utility model belongs to the field of power line engineering, and particularly relates to a handle device for a cement pole upright.

Background

The electric power construction engineering transmission line construction is often all the ground field, and the pole needs to be erected in the position of mountain slope, farmland etc. unable to use auxiliary pole setting of crane, if only rely on the manpower and do not assist the instrument and be unable to erect the pole, need design department an auxiliary device of carrying out the pole setting.

Disclosure of utility model

The utility model provides a self-control simple and easy barre under the mechanical pole setting operation condition that can't use the crane has simple structure, the cement pole setting that is suitable for the scene is many uses the barre.

A handle device for a cement pole vertical rod is characterized by comprising a flange plate, supporting legs, fixed pulleys and a manual winch, wherein three hinged lugs are uniformly welded on the bottom surface of the flange plate, the hinged lugs are distributed in a circular array at the center of the flange plate, the angle between the hinged lugs is 120 degrees, a hook is arranged at the center of the bottom surface of the flange plate, the fixed pulleys are hung on the bottom surface of the flange plate, the top of each supporting leg is hinged with each hinged lug, the supporting legs are divided into two sections, a limit ring is welded inside the joint of the two sections, the two sections are connected by using a hoop fastened by bolts outside, and the manual winch is fixed on the lower part of any supporting leg and is provided with a gear set and a locking part.

Further, the leg is made of phi 159 x 4.5 steel pipe, the total length of the leg is 7m, and each section is 3.5m.

Further, the flange plate is a round steel plate, and the thickness is 12mm.

Further, the steel rope in the manual winch uses a phi 10mm,6 x 37 fiber core steel rope.

The device has the advantages that the cement pole head can be lifted up by using the device under the condition that the crane cannot be used for pole setting operation, and the root of the pole is placed into a pre-dug pole hole. By utilizing the device, the problem that the cement wire rod cannot be installed by using an automobile crane in hillside fields, farmlands and the like during construction of field power lines can be effectively solved.

Detailed Description

Example 1 an engineering is to erect a cement pole on a hillside land, an operator digs a pole hole in advance, and conveys the pole to the side of the pole hole. Subsequently, a cement pole is erected with a pole device comprising a flange plate 1, a leg 3, a fixed pulley 2 and a manual winch 6, the flange plate 1 being made of a circular steel plate with a thickness of 12mm. The bottom surface of the flange plate 1 is uniformly welded with three hinged ears 7 made of 12mm steel plates, the hinged ears 7 are distributed in a circular array at the center of the flange plate 1, the angle between the hinged ears is 120 degrees, and a hook is arranged at the center of the bottom surface of the flange plate 1 and is hung with a fixed pulley 2. The top of the supporting leg 3 is hinged with the hinged ear 7, the supporting leg 3 is divided into two sections, a limit ring 5 is welded inside the joint of the two sections, the two sections are connected by using a hoop 4 fastened by bolts, the supporting leg 3 is made of phi 159 multiplied by 4.5 steel pipes, the total length of the supporting leg 3 is 7m, and the length of each section is 3.5m. The manual winch 6 is fixed at the lower part of any landing leg 3, a steel rope of phi 10mm and 6 multiplied by 37 fiber core steel wire ropes are used as steel ropes in the manual winch 6, a gear set and a locking part are arranged on the manual winch 6, the gear set is used for reducing the moment of a manual wheel, and the locking device can ensure that the roller is locked when the manual wheel does not apply acting force.

When the device is used, the steel rope of the manual winch 6 is hung into the fixed pulley, and then an operator erects the device and levels the ground where the supporting leg 3 is placed. Because the supporting leg 3 is arranged on the ground, the supporting leg 3 can sink into the ground after being in place and stressed, and a limiting device is not needed to be additionally arranged. The pole uses nylon suspender, and its bolting position selects 3/5 of pole total length to lean on pole upper portion position, and the suspender is connected with the steel cable, and the operating personnel operates manual capstan 6 and lifts the pole to pole root leave ground, rotates the pole, aligns the pole root pole hole, operates manual capstan 6 and slowly puts down the pole and falls into the pole hole.
