With the continuous improvement of voltage grade, large-scale iron towers are widely used in ultra-high voltage power transmission and transformation projects, and generally, the steel pipe tower parts are large, the cross arm is long, the structure size is large, and the single piece is heavy, which leads to relatively large difficulty in tower assembly construction, and the parallel line with point line is often characterized, the traditional embrace pole is relatively large influenced by topographic conditions, and part of tower positions cannot meet the actual demand of normal tower assembly.

DETAILED DESCRIPTION

[0024] The technical scheme in the embodiment of the utility model will be clearly and completely described below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art belong to the scope of protection of the utility model.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection or a movable connection, a detachable connection or a non-detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection or a connection that can communicate with each other; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements, an indirect connection, or an interaction between two elements.

[0029] The present invention will now be described in detail with reference to the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] This utility model addresses the high failure rate of existing fuel-driven hydraulic systems by providing a ground-mounted, pole-lifting, new energy electric hydraulic pump station, such as... Figure 1 , 2 As shown, the hydraulic pump station is used to drive the ground-mounted mast. It includes a pump station frame 1, and a hydraulic oil tank 2, an oil pump 4, and a hydraulic valve group 3 connected in sequence inside the pump station frame 1. The pump station frame 1 also includes an electric motor 5 and a storage battery 6. The oil pump 4 is driven by the electric motor 5, which is a DC electric motor 5 and can be powered by the storage battery 6. The outlet of the hydraulic valve group 3 is provided with a quick connector 10 for connecting the cylinder of the hydraulic mast.

[0031] Furthermore, it also includes an electrical control box 7 and an operation panel 8. The electrical control box 7 is used to control the electric motor 5 and the hydraulic valve group 3. The operation panel 8 is equipped with a display screen, which can display the data of the hydraulic system in real time, such as the voltage and current of the electric motor 5, the speed of the hydraulic motor, the usage and remaining working time of the lithium battery, the hydraulic oil temperature, the system pressure and other related parameters, which facilitates human-machine interaction.

[0032] By using an electric motor (5) instead of a traditional diesel or gasoline engine, the hydraulic oil flow rate in the hydraulic circuit can be significantly improved, thereby achieving stable control of the lifting speed during the ground-mounted boom lifting operation and ensuring the overall dynamic response and energy efficiency of the hydraulic system. Overall, this results in a highly efficient and energy-saving hydraulic power source system, improving system stability and reducing system energy consumption. Furthermore, it significantly reduces the size of the device.

[0033] By setting up a storage battery 6 for energy storage, an electrical control box 7 for control, and a display screen on the operation panel 8 for information display, the system achieves efficient storage and scheduling of electrical energy for the new energy electric hydraulic system used for lifting the ground-mounted pole. By precisely adjusting the power output of the electric motor 5, the system maximizes the utilization of resources.

[0034] In a preferred embodiment of this utility model, a remote control terminal is also included, which is wirelessly connected to the electrical control box 7.

[0035] During operation, the DC motor 5 drives the oil pump 4 to rotate, thereby causing the hydraulic oil to flow in the pipeline. The hydraulic valve group 33 uses a manual / electric dual-control valve, which can be operated manually or controlled by the electrical control box 7, and can be remotely controlled by a wireless remote control terminal.

[0036] like Figure 3 As shown, in a preferred embodiment of this utility model, the hydraulic valve group 3 includes a first check valve 31 and a second check valve 32 to realize a bidirectional locking circuit. When the first check valve 31 is opened, the hydraulic oil tank 2 discharges hydraulic oil outward and enters the lower chamber of the lifting cylinder. At the same time, by controlling the opening of the check valve at the outlet of the upper chamber of the lifting cylinder, the hydraulic oil in the upper chamber of the lifting cylinder returns to the oil tank, thereby achieving the lifting effect. When the second check valve 32 is opened, the hydraulic oil returns to the hydraulic oil tank 2.

[0037] The operation of lifting poles on the ground often requires the coordinated operation of two lifting hydraulic cylinders on both sides of the lifting mechanism. In order to ensure construction quality, improve lifting efficiency, and ensure construction safety, it is necessary to consider the synchronous lifting of the two lifting cylinders. The new energy electric hydraulic system for lifting poles on the ground achieves synchronous lifting of the poles on the ground by installing a first diverter valve 21, a second diverter valve 22, a first throttle valve 41, a second throttle valve 42, a third throttle valve 51, and a fourth throttle valve 52.

[0038] In a preferred embodiment of this utility model, the hydraulic valve group 3 further includes a safety relief valve, which reduces the pressure of the hydraulic circuit by discharging hydraulic oil.

[0039] The hydraulic cylinder needs to be synchronized during lifting and lowering, requiring speed regulation. Therefore, speed regulation devices need to be added to the inlet and outlet ports of the hydraulic cylinder, including a first speed regulation device and a second speed regulation device. The first speed regulation device is connected in series with the first check valve 31, and the second speed regulation device is connected in series with the second check valve 32. In the inlet throttling speed regulation circuit, the return oil line pressure is low. During the lifting process of the landing mast, the piston rod can be pushed out of the hydraulic cylinder at a low speed with a large thrust. However, because the cylinder has no back pressure and the movement is unstable, vibration and creep of the lifting cylinder occur during the lifting process. In addition, this circuit is prone to leakage when the oil temperature rises. Therefore, it is suitable for low-speed operation under load changes.

[0040] In a preferred embodiment of this utility model, the hydraulic valve group 3 further includes two three-position four-way valves, including three-position four-way valve A61 and three-position four-way valve B62, which are used for reversing operations. Their function is to ensure that when the landing boom stops at any position during the lifting or lowering process, the three-position four-way valve is switched to the middle position, so that the hydraulic cylinder can achieve bidirectional locking.

[0041] In summary:

[0042] The utility model discloses a battery 6 as energy source instead of internal combustion engine drive pump station with power control management system, and realizes modular installation and removal, and is convenient for maintenance, transportation. Through closed loop control strategy and sensor feedback, realize the closed loop control of hydraulic system jacking driving force, realize the synchronous jacking of pole holding through the intelligent management of electric proportional valve program, and further improve the reliability and stability of landing pole holding hydraulic jacking system, improve the efficiency and construction safety of transmission line group tower construction.

[0043] The above only for the preferred embodiment of the utility model, and is not used to limit the utility model, for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
