Description

Technical Field

[0001] This invention relates to a cable winding and unwinding vehicle, and particularly to the field of cable winding and unwinding equipment technology. Background Technology

[0002] Cable reel-in / delivery vehicles are power engineering machines equipped with an autonomous power system and complete braking and anti-reverse devices, capable of self-lifting cable spool operations. They are mainly used in rural and urban power grid renovation projects for cable reel-in, cable laying, and cable replacement operations. A diesel or gasoline engine drives a reduction gear to achieve the complete reel-in or unwinding of the conductor. This mechanical operation mode replaces the traditional manual cutting of conductors and ground-based reel-pushing methods, reducing the risk of damage to crops and urban facilities. It also supports the reuse of empty cable spools and adjustable laying length.

[0003] The current cable winding and unwinding operations mainly rely on manual labor, which has problems such as low efficiency, high labor intensity and high safety risks. When two cable unwinding vehicles work together, there is no effective speed regulation and matching mechanism, making it difficult to ensure the synchronization and stability of the cable unwinding and unwinding processes. In addition, the equipment has limited adaptability to cable reel specifications, making it difficult to meet the operational needs of cable reels of different sizes. Summary of the Invention

[0004] This invention provides a cable winding and unwinding vehicle to overcome the shortcomings of existing technologies, such as low efficiency, high cost, and significant safety hazards associated with manual operations, as well as poor equipment adaptability and difficulty in matching the speed of coordinated operations.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention discloses a cable reeling and laying vehicle, including a vehicle body, with independently operating left and right reeling and laying components respectively located on the front sides of the vehicle body. Above the left and right reeling and laying components, there are cabs and covers respectively. Front wheels are located below the left and right reeling and laying components, and rear wheels are located at the bottom of the vehicle body.

[0006] The left retraction and extension assembly includes a left lifting arm, which is connected to a chuck via a power system, and a left transverse frame is located below it.

[0007] The right retraction assembly includes a right lifting arm and a right transverse frame located below it.

[0008] The power system includes a hydraulic motor, which controls the rotational speed of the gear module connected to it, and the gear module is connected to a chuck.

[0009] Furthermore, both the left and right lifting arms achieve lifting and lowering actions through lifting cylinders respectively installed on the left and right transverse frames. The left and right transverse frames are connected by transverse cylinders to achieve independent horizontal adjustment. Both ends of the two frames are equipped with front telescopic cylinders and rear telescopic cylinders respectively to achieve independent length adjustment.

[0010] Furthermore, a hydraulic oil tank is located between the cab and the cover, and a gearbox is located below the hydraulic oil tank. The travel motor is connected to the gearbox, the gearbox is connected to the drive shaft, and the drive shaft is connected to the drive steering axle to drive the rear wheels.

[0011] Furthermore, the cab includes a seat, with a rotary switch and throttle control knob on one side and a pilot switch and aviation handle on the other side. Below the seat are two-way pedals, and in front of it is a steering wheel with a key switch. In front of the steering wheel are a handbrake and an instrument panel with a display screen. In front of the instrument panel is a control cabinet.

[0012] Furthermore, a diesel tank and battery are installed in the vehicle body below the cab. One end of the pump is connected to the hydraulic oil tank, and the other end is connected to the multi-way valve in the electro-hydraulic system. The radiator is connected to both the multi-way valve and the hydraulic oil tank. A pilot oil source valve is installed at the rear end of the pump, and the pilot oil source valve is connected to the electro-hydraulic system.

[0013] Furthermore, a canopy is provided above the cab, with taillights on the rear side and headlights and turn signals on the front side.

[0014] The beneficial effects achieved by this invention are as follows: by setting an independent engine speed regulating device to adjust the oil supply of the hydraulic pump to control the rotation speed of the rotary motor, the problem of speed matching in linkage operation is solved; the large load-bearing structure design and adjustable fixing mechanism are adopted to adapt to various cable reel specifications; and with the hydraulic control system and remote control operation, mechanized collaborative operation is realized, effectively improving work efficiency and safety.
