Abstract
Description
Technical Field
[0001] This application relates to the field of power line construction technology, and in particular to an installation tool for power duct laying. Background Technology
[0002] Power ducts are specialized conduits designed to meet the requirements of substation cable entry / exit channels and overhead line burial, providing power supply channels for adjacent plots. Also known as cable conduits, power cable conduits, cement cable conduits, and power ducts, power ducts are characterized by high strength and low frictional resistance. They are typically constructed concurrently with road or municipal pipeline projects. However, current technologies for power duct installation have some shortcomings. One step in power pipeline construction is the lowering of the power ducts. Power ducts are dedicated conduits for substation cable entry / exit and overhead line burial, and they also provide supporting power to adjacent plots. Current power duct lowering operations typically employ mechanical batch hoisting or manual individual lowering. However, due to the depth of the power pipeline pit, it is difficult for machinery operators or workers to control the power ducts during the lowering process. This leads to excessive wear and tear due to frequent slippage and contact with the pit walls, and also increases the risk of safety accidents. Summary of the Invention
[0003] This application provides an installation tool for power ductwork to solve the problems of excessive wear and safety accidents caused by frequent slippage and collisions with the pit walls during the lowering process of power ductwork in existing mechanical batch hoisting or manual individual lowering, due to the deep pit of the power ductwork and the difficulty for machine operators or workers to control the ductwork during the lowering process. The tool uses a hydraulic station to flow hydraulic oil into the cylinder through hydraulic hoses. The cylinder controls the up and down movement of the support plate. The crane places the ductwork onto the support plate, and the support plate moves down through the cylinder to transport the ductwork into the deep pit. The mechanism is simple, the transportation is stable, and no manual transportation is required, saving time and effort.
[0004] This application provides an installation tool for power duct laying, including a positioning frame, characterized in that: a hydraulic cylinder is fixed to the positioning frame, a load-bearing plate is fixed to the hydraulic cylinder, a guide ring bracket is fixed to the load-bearing plate, a guide ring is fixed to the guide ring bracket, a guide rod is movably connected to the guide ring, the guide rod is fixed to the positioning frame, a hydraulic station is fixed to the positioning frame, and the hydraulic station is pipe-connected to the hydraulic cylinder.
[0005] Preferably, the load-bearing plate is fixed with an anti-roll bracket, and the anti-roll bracket is fixed with a rubber block.
[0006] Preferably, a square tube is fixed below the load-bearing plate.
[0007] Preferably, the guide rod is provided with buffer blocks at the top and bottom.
[0008] Preferably, the positioning frame is fixed with a crossbeam.
[0009] Preferably, a motor is fixed below the positioning frame, and the motor is fixed with rollers.
[0010] Preferably, the positioning frame is fixed with reinforcing ribs.
[0011] Beneficial effects:
[0012] Considering that existing power duct laying operations usually employ mechanical batch hoisting or manual one-by-one laying methods, the deep depth of power pipeline pits makes it difficult for machinery operators or workers to control the power ducts during the laying process. This results in excessive wear and tear on the power ducts due to frequent slippage and contact with the pit walls, which can easily lead to safety accidents.
[0013] Hydraulic oil is pumped through a hydraulic station and hydraulic hoses into a hydraulic cylinder. The cylinder controls the up-and-down movement of the load-bearing plate, allowing a crane to place the pipeline onto the plate. The load-bearing plate then lowers via the hydraulic cylinder, transporting the pipeline into the pit. The mechanism is simple, provides stable transport, and eliminates the need for manual labor, saving time and effort. Anti-roll supports with rubber blocks are installed on the load-bearing plate to prevent the pipeline from rolling sideways during the descent. The rubber blocks protect the pipeline from damage caused by mechanical vibrations during transport. A square tube beneath the load-bearing plate increases its rigidity, significantly enhancing its load-bearing capacity. Buffer blocks above and below the guide rods reduce vibration during the load-bearing plate's movement, especially at its limit positions, protecting the mechanical structure and extending its lifespan. A crossbeam in the positioning frame enhances its rigidity, reducing machine vibration. A motor with rollers located beneath the positioning frame allows workers to adjust the pipeline's lowering position based on its location, eliminating the need for manual or heavy machinery handling, reducing costs and increasing efficiency. By adding reinforcing ribs to the positioning frame, the rigidity of the positioning frame is enhanced, increasing its strength and indirectly strengthening the load-bearing capacity of the load-bearing plate.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-4 The installation tool for power duct laying shown includes a positioning frame 1, a hydraulic cylinder 2 fixed to the positioning frame 1, a load-bearing plate 3 fixed to the hydraulic cylinder 2, a guide ring bracket 4 fixed to the load-bearing plate 3, a guide ring 5 fixed to the guide ring bracket 4, a guide rod 6 movably connected to the guide ring 5, a guide rod 6 fixed to the positioning frame 1, a hydraulic station 8 fixed to the positioning frame 1, and a hydraulic station 8 pipe connected to the hydraulic cylinder 2.
[0029] Hydraulic oil is pumped from hydraulic station 8 through hydraulic hose into cylinder 2. Cylinder 2 controls the up and down movement of support plate 3, allowing the crane to place the pipe onto support plate 3. Support plate 3 then moves down via cylinder 2 to transport the pipe into the deep pit. The mechanism is simple, the transport is smooth, and no manual transport is required, saving time and effort.
[0030] The load-bearing plate 3 is fixed with an anti-roll bracket 10, and the anti-roll bracket 10 is fixed with a rubber block 11.
[0031] Among them, the anti-roll bracket 10 is set by the load-bearing plate 3, and the anti-roll bracket 10 is equipped with rubber blocks 11, so that the pipeline will not roll sideways during the downward movement of the load-bearing plate 3, and the rubber blocks 11 protect the pipeline from collision damage caused by mechanical vibration during transportation.
[0032] A square tube 15 is fixed below the load-bearing plate 3.
[0033] The square tube 15 installed below the load-bearing plate 3 increases the rigidity of the load-bearing plate 3, greatly enhancing its load-bearing capacity.
[0034] The guide rod 6 is equipped with buffer blocks 12 at the top and bottom.
[0035] Among them, buffer blocks 12 are provided above and below the guide rod 6, which reduces the vibration of the load-bearing plate 3 when it stops at the limit position during the up and down movement, thus protecting the mechanical structure and increasing its service life.
[0036] The positioning frame 1 is fixed with a crossbeam 13.
[0037] The use of a crossbeam 13 in the positioning frame 1 improves the rigidity of the positioning frame 1 and reduces machine vibration.
[0038] A motor 14 is fixed below the positioning frame 1, and a roller 9 is fixed to the motor 14.
[0039] The system features a motor 14 positioned below the positioning frame 1, with rollers 9 mounted on the motor 14. This allows workers to adjust the pipe's lowering position based on its location below, eliminating the need for manual or heavy machinery handling, thus reducing costs and increasing work efficiency.
[0040] The positioning frame 1 is fixed with reinforcing ribs 7.
[0041] The rigidity of the positioning frame 1 is enhanced by setting the reinforcing rib 7, which increases the strength of the positioning frame 1 and indirectly enhances the load-bearing capacity of the load-bearing plate 3.
[0042] Working principle: When using this installation tool for power duct laying, hydraulic oil is pumped through the hydraulic station 8 and flows into the cylinder 2 via the hydraulic hose. The cylinder 2 controls the up and down movement of the support plate 3, allowing the crane to place the pipe onto the support plate 3. The support plate 3 is then lowered by the cylinder 2 to transport the pipe into the pit. The support plate 3 is equipped with an anti-roll bracket 10, which has rubber blocks 11 to prevent the pipe from rolling sideways during the descent of the support plate 3. The rubber blocks 11 protect the pipe from collision damage caused by mechanical vibration during transportation. A motor 14 with rollers 9 is installed below the positioning frame 1, allowing workers to adjust the lowering position of the pipe according to its location. This eliminates the need for manual or heavy machinery handling, reducing costs and increasing work efficiency.
[0043] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it.
