Description

Technical Field

[0001] This invention relates to hydraulic auxiliary devices for power supply equipment, and particularly to a portable hydraulic station device for overhead line equipment. Background Technology

[0002] In the construction of overhead power transmission lines, various stringing tools are frequently used to complete operations such as line splicing, line breaking, and conductor tightening. Existing stringing tools include splicing clamp installation tools, line cutters, temporary tensioners, etc. Some stringing tools are hydraulically driven. Hydraulically driven tools require hydraulic drive systems such as oil pumps, oil tanks, and various valve groups. However, existing hydraulic drive systems have the following disadvantages:

[0003] 1. Since the working environment for overhead line work is mostly open-air, the existing complete hydraulic drive system also needs to be equipped with generators and other equipment. The whole system has disadvantages such as large size, inability to achieve remote wireless control for live work, complex equipment, and inconvenience in carrying and relocating. It is not conducive to portability and cannot be used for long-distance wireless remote control of live construction operations.

[0004] 2. Currently, most hydraulic drive systems equipped for overhead line tools are single-circuit systems, with only a single interface for both oil inlet and outlet, which cannot meet the needs of overhead line tools that require continuous oil circulation output.

[0005] The invention disclosed in application number CN202211545636.5 is a hydraulic oil cooling device and cooling method for a hydraulic station, comprising: a support frame, a control module, a monitoring module, a pre-cooling mechanism, a cooling and heat preservation mechanism, an outlet pump, a solenoid valve, an inlet pump, and a refrigeration unit; the control module is located at the bottom front end of the support frame; the pre-cooling mechanism is located inside the support frame; the cooling and heat preservation mechanism is located at the top front of the pre-cooling mechanism; the outlet pump is installed at the top of the pre-cooling mechanism and located in front of the cooling and heat preservation mechanism; the solenoid valve is located on the right side of the top of the pre-cooling mechanism; the inlet pump is located on the rear side of the top of the pre-cooling mechanism; and the refrigeration unit is located on the right side of the pre-cooling mechanism.

[0006] Since the aforementioned patented technology is not designed for overhead line erection tools used in the construction of power transmission and transformation overhead lines, it cannot be used in the construction of power transmission and transformation overhead lines and suffers from all the problems existing in the prior art. Summary of the Invention

[0009] (1) How to reasonably design the internal structure of the hydraulic station device, reduce the overall weight and volume of the hydraulic station device, facilitate its transport and relocation, and meet the needs of continuous construction operations in multiple locations.

[0010] (2) How to design the hydraulic station device as a system where single oil circuit system and dual oil circuit system coexist, so as to meet the various hydraulic drive requirements of the overhead line tool.

[0014] Includes oil pump, oil reservoir, oil outlet module, oil return module, pressure relief valve, and control components;

[0015] The oil reservoir is connected to the oil pump inlet. The oil outlet module is provided with an oil outlet path. The beginning port of the oil outlet path is connected to the oil pump output port, and the end port of the oil outlet path is connected to the external overhead line equipment. The oil outlet module also has a first connecting hole, which is connected to the oil outlet path.

[0016] The oil return module is equipped with an oil return passage. The beginning port of the oil return passage is connected to the external overhead line equipment, and the end port of the oil return passage is connected to the oil reservoir. The oil return module also has a second connecting hole, a first pressure relief hole, a second pressure relief hole, and a plunger hole. One end of the second connecting hole of the oil return module is connected to the first connecting hole of the oil outlet module, and the other end of the second connecting hole of the oil return module is connected to one end of the first pressure relief hole. The other end of the first pressure relief hole is connected to the first connecting hole of the pressure relief valve.

The end of the plunger hole is connected to the second connecting hole of the oil return module through a control port, and the plunger hole is also connected to the oil return passage.

[0017] The control components include a servo motor and a plunger. The plunger is mounted on the servo motor and extends into the plunger hole of the oil return module. The plunger can be sealed and engaged with the control port at the end of the plunger hole. The servo motor can control the plunger to reciprocate along the axial direction of the plunger hole.

[0024] As a preferred option for the portable hydraulic station device specifically designed for this overhead line equipment, the oil pump is powered by a portable power supply.

[0025] 3. Beneficial effects

[0026] With this structure, the oil reservoir stores the oil, and the oil pump outputs the oil from the oil outlet module to the external wiring tool. The oil inside the wiring tool can also be recovered using either the oil outlet module or the oil return module. During use, the pressure value of the pressure relief valve in the oil return circuit can be adjusted by setting the threshold of the pressure relief valve. Furthermore, manual pressure relief and oil return are achieved by using the servo motor of the control component to actuate the plunger. Compared to other pressure relief methods, the servo motor controls the plunger to open the control port at the end of the plunger hole, which can completely remove the oil.

[0027] In addition, by using an oil outlet module and an oil return module to replace the previous pipeline connection, the various liquid circuits are integrated, reducing the space occupied by the original pipelines. Furthermore, by summing up all the liquid circuits into the oil outlet module and the oil return module, the direction of the oil can be defined, and it is also convenient to connect and install with various valve groups, reducing the leakage caused by loose or faulty pipeline connections.

[0028] The beneficial technical effects of this portable hydraulic station device specifically designed for overhead line equipment are as follows:

[0029] (1) This portable hydraulic station for overhead line equipment uses a portable power source and does not require additional equipment such as a generator. With the oil outlet module and oil return module, this portable hydraulic station for overhead line equipment has the advantages of reasonable internal structure distribution, small size and easy to carry, and is suitable for continuous construction operations in multiple locations.

[0030] (2) The dedicated portable hydraulic station device for this overhead line equipment can be a single oil circuit system or can use a dual interface of oil outlet module and oil return module to meet the needs of overhead line tools with continuous oil output.

[0031] (3) Due to the wireless receiving module of the control circuit and the wireless module of the remote control servo motor, all functions of the dedicated portable hydraulic station device for this overhead line equipment can be remotely controlled. Specifically, the output power of the oil pump can be controlled by the wireless receiving module of the control circuit to achieve remote and precise control of the output hydraulic pressure. The speed of oil return and pressure relief can be adjusted by the wireless module of the remote control servo motor.

[0032] Compared to existing technologies, this portable hydraulic station for overhead line equipment not only enables remote control of all functions, but also meets different oil inlet or return requirements according to the needs of external overhead line equipment. Attached Figure Description
