Description

Technical Field

[0001] This invention belongs to the field of power construction equipment technology, specifically relating to a pole erection device and method, applicable to concrete / wooden pole erection construction in mountainous areas, fields, forests and other conditions where large lifting machinery cannot enter the site. Background Technology

[0002] When upgrading power distribution networks in remote areas such as mountainous, hilly, and farmland areas, cranes and hydraulic pole erecting machines are difficult to access due to narrow roads and uneven terrain. Most existing pole erecting equipment relies on external power sources such as motors and hydraulic oil sources, and cannot be used in scenarios where there is no power supply or fuel supply in the field.

[0003] The pole erection device disclosed in patent document CN210598374U relies on a dual power drive of hydraulic cylinder and motor. The equipment is integrated and cannot be disassembled for transportation. The hydraulic components are too heavy, making manual transportation difficult on rugged mountain roads. The steel cable pulls the tail of the chute to lift the pole, and the pulling force point is at the rear end of the chute. During the pole erection process, the pole is prone to displacement, and the wall of the pole pit is prone to collapse due to the impact of the pole end.

[0004] Patent document CN113585859A discloses a simple pole erection device. Although it adopts a non-powered pole erection scheme, it cannot flexibly adjust the tilt angle according to the pole specifications, materials and site conditions, and it is not convenient to control the speed of the pole guide. In addition, the baffle structure at the front end of the pole guide groove is inconvenient to operate, resulting in low work efficiency. Furthermore, the device structure is relatively complex.

[0005] In summary, there is an urgent need to develop a pole erection device and method with a simpler overall structure, more convenient pole operation, and flexible tilt angle adjustment, which can efficiently achieve unpowered pole erection in the field. Summary of the Invention

[0006] The purpose of this invention is to develop a pole erection device and method with a simpler overall structure, more convenient pole operation, and flexible adjustable tilt angle, which can efficiently achieve pole erection without power in the field.

[0007] To achieve one of the above-mentioned objectives, the present invention adopts the following technical solution: A pole erection device includes a sliding mechanism disposed on one side of a pole pit and a protective component disposed within the pole pit to protect the pole pit. The protective component is disposed on the opposite side of the sliding mechanism. The sliding mechanism includes a base plate and a mounting plate. A traveling mechanism and a fixing mechanism are disposed below the base plate. The top of the mounting plate is provided with a pole sliding groove for placing the pole. The top of the base plate is provided with a side guard plate and a mounting plate tilt adjustment mechanism. One end of the mounting plate near the pole pit is hinged between two oppositely disposed side guard plates via a pivot. The mounting plate tilt adjustment mechanism is disposed below the mounting plate and is used to adjust the angle between the mounting plate and the horizontal plane between 30° and 60°. The lower end of the pole sliding groove corresponds to the pole pit, and the lower end of the pole sliding groove is provided with a stop mechanism that can be operated from the other end of the mounting plate. The stop mechanism is used to limit the position of the pole before the sliding operation.

[0008] Preferably, the base plate is rectangular, and the traveling mechanism includes casters arranged in an array below the four corners of the base plate to facilitate the movement of the gliding mechanism.

[0009] Preferably, the fixing mechanism includes a fixing plate and a ground-inserting cone. The fixing plate is connected to the end of the base plate away from the pole pit. The upper part of the ground-inserting cone is provided with a threaded section, which is threaded into a threaded hole on the fixing plate. The lower part of the ground-inserting cone is provided with a spiral blade for drilling, and the bottom of the ground-inserting cone is cone-shaped, which can firmly fix the sliding mechanism and prevent the sliding mechanism from moving during sliding operations.

[0010] Preferably, the protective component includes a semi-circular protective plate with an inner diameter larger than the outer diameter of the pole and the outer diameter of the protective plate matching the inner diameter of the pole pit. A support plate fixed to the edge of the pole pit is provided on the side of the protective plate away from the pole. The support plate is provided with a second fixing mechanism, which can effectively protect the pole pit when the pole is discharged, prevent the pole pit from being deformed by force, and affect the erection quality of the pole.

[0011] Preferably, the fixing mechanism two includes a ground-inserting cone two, the upper part of which is provided with a threaded section two, the threaded section two being threadedly connected to a threaded hole two provided in the support plate, the lower part of which is provided with a spiral blade two for drilling, and the bottom of the ground-inserting cone two being cone-shaped, which can firmly fix the protective component and prevent the protective component from moving during the sliding operation.

[0012] Preferably, the protective plate is provided with an anti-wear liner on the side near the pole. The anti-wear liner is made of wear-resistant rubber material, which can effectively prevent the pole from rubbing against the protective plate during the sliding process and damaging the surface of the pole.

[0013] Preferably, the mounting plate tilt adjustment mechanism includes a slider with an arc-shaped support surface and a front support and a rear support correspondingly disposed on the base plate. A screw and a guide rod are arranged parallel between the front support and the rear support, with the guide rod located below the screw. The slider has a screw hole and a guide hole that respectively cooperate with the screw and the guide rod. The slider is slidably connected to the guide rod through the guide hole, and the slider is threadedly connected to the screw through the screw hole. The end of the screw away from the front support passes through the rear support and is fixedly connected to a crank handle. A set screw is threadedly connected to the crank handle. When the set screw is tightened, it can abut against the rear support, enabling quick adjustment of the mounting plate tilt angle to adapt to the slinging operation of poles of different lengths and weights.

[0014] Preferably, the stop mechanism includes a rope hole and a telescopic cavity disposed within the mounting plate. A top rod is slidably connected within the telescopic cavity. The top of the top rod is hemispherical, and a pull plate is provided at the bottom of the top rod. The opening of the telescopic cavity is smaller than the diameter of the pull plate, and a tension spring is provided between the opening of the telescopic cavity and the pull plate. In its natural state, the tension spring pulls the pull plate closer to the opening of the telescopic cavity, causing the top rod to protrude upward into the pole groove, thereby holding the pole in place within the pole groove. A pulley is rotatably connected to the bottom of the telescopic cavity. One end of the rope hole is connected to the bottom of the telescopic cavity, and the other end extends to the end of the mounting plate away from the pole pit. A pulley is correspondingly provided at the end of the mounting plate away from the pole pit. A pull rope is threaded through the rope hole. One end of the pull rope passes around the pulley and is fixedly connected to the bottom of the mounting plate, while the other end of the pull rope passes around the pulley and extends out to the outside of the rope hole. This allows for quick operation of the stop mechanism to release the obstruction of the pole, enabling the pole to slide into the pole pit along the pole groove by its own weight.

[0015] Preferably, the upper part of the pole is provided with an auxiliary hanging lug, and a traction rope is provided on the auxiliary hanging lug, so that after the slinging operation is completed, the position of the pole can be manually adjusted, the protective parts in the pole pit can be removed, the pole can be aligned, and the pole pit can be poured and backfilled.

[0016] To achieve another objective of the present invention, this application proposes a method for erecting utility poles based on the above-described pole erection device, comprising the following steps: S1. Move the slinging mechanism with the pole placed to the side of the pole pit, and place a blocking block next to the pole pit to prevent the slinging mechanism from moving forward. Then fix the slinging mechanism by fixing the fixing mechanism. S2. Secure the protective components from the opposite side of the sliding mechanism into the pole pit; S3. Adjust the angle between the mounting plate and the horizontal plane using the mounting plate tilt adjustment mechanism to a position that allows the pole to slide by its own weight. S4. Quickly operate the stop mechanism to release the obstruction to the pole, allowing the pole to slide into the pole pit along the pole groove by its own weight; S5. Manually adjust the position of the pole, remove the protective parts from the pole pit, align the pole, and pour and backfill the pole pit.

[0017] Compared with the prior art, the present invention has the following technical effects: The invention features a simpler overall structure, more convenient operation of the pole guide, and flexible adjustment of the tilt angle, enabling efficient pole erection without power in the field.
