Description

Technical Field

[0001] The utility model relates to the field of hydraulic stations, in particular to an energy storage hydraulic station. Background Art

[0002] The hydraulic station is an independent hydraulic device that can supply oil according to the requirements of the drive device and effectively control the flow direction, pressure and flow of the hydraulic oil. The user only needs to connect the hydraulic station with the actuator on the host through the oil pipe, and the hydraulic machinery can achieve various prescribed actions and working cycles.

[0003] A hydraulic station usually includes an oil tank, a drive device, a control unit, a sensor instrument, and a valve device. Existing hydraulic stations are usually in the form of direct supply. The control unit controls the drive device to pump fluid from the oil tank. When the hydraulic oil pressure displayed by the sensor instrument reaches the predetermined pressure, the valve device is opened, and the hydraulic oil can be directly pumped to the actuator. However, the hydraulic station in the form of direct supply needs to restart the pressurization of the hydraulic oil every time it is shut down and re-pumped. It takes a long time to reach the predetermined pressure, which is inefficient. Utility Model Content

[0004] In order to improve the operating efficiency of the hydraulic station pump, the utility model provides an energy storage hydraulic station.

[0007] By adopting the above technical solution, by adding an oil storage tank to the system of the hydraulic station, the driving device can first fill the oil storage tank when pumping oil, and then pump the hydraulic oil from the oil storage tank into the external actuator through the valve device. After one pumping, when the driving device is controlled to pump the oil next time, the driving device does not need to pressurize the oil storage tank, but can directly pump out the hydraulic oil. Compared with the direct supply method in the prior art that requires long-term pressurization each time, the above system structure has higher operating efficiency.

[0008] Furthermore, by arranging a shock absorbing mechanism on the mounting device, when the oil storage tank is mounted on the oil tank through the mounting device, the connection stability is better, and it is not easy to be affected by the vibration of the equipment to cause connection abnormalities, and it is not easy to cause oil leakage and the like.

[0010] By adopting the above technical solution, when installing the mounting frame, the mounting frame is first vertically inserted into the mounting vertical bar, and then the mounting frame and the mounting vertical bar are fixed with connecting bolts. The above structural connection has good stability and is fixed by only two bolts, which is convenient for disassembly and assembly.

[0011] Optionally, the mounting frame includes a vertical frame arranged vertically, a mounting cross frame connected to the top of the vertical frame, and a bottom frame horizontally connected to the bottom of the vertical frame and used for mounting the oil storage tank; the mounting groove is located on the mounting cross frame; the shock absorbing mechanism includes a lateral shock absorbing assembly and a longitudinal shock absorbing assembly, the lateral shock absorbing assembly is located on the vertical frame; the longitudinal shock absorbing assembly is located at the bottom of the bottom frame.

[0013] By adopting the above technical solution, when the hydraulic station generates lateral vibration, the vertical frame can move slightly horizontally on the shock-absorbing bolts, and the lateral vibration is released through the shock-absorbing springs on both sides of the vertical frame, so that the oil storage tank is not significantly affected by the vibration.

[0014] Optionally, the longitudinal shock absorbing assembly includes a weight-bearing seat installed on the base frame, a sliding rod horizontally passing through both ends of the weight-bearing seat, a damping column horizontally slidably installed on the sliding rod, and a damping spring; the weight-bearing seat has a movable chamber for the movement of the damping column; the damping spring is mounted on the sliding rod and located at both ends of the damping column to always drive the damping column to be located in the middle of the movable chamber.

[0015] By adopting the above technical solution, when the hydraulic station vibrates longitudinally, the damping column can slide horizontally on the sliding rod and release the longitudinal vibration under the action of the damping springs at both ends. The damping springs on both sides of the damping column can always drive the damping column back to the middle of the moving chamber, so that the damping column always plays a shock-absorbing role.

[0016] Optionally, vertical plates are provided on both sides of the base frame, and the vertical plates, the base frame and the vertical frame surround to form an installation cavity for installing the bottom of the oil storage tank, and a sponge block adapted to the bottom of the oil storage tank is provided in the installation cavity; fixing bolts are provided on the base frame, and the fixing bolts pass through the sponge block, the base frame and the longitudinal shock absorbing assembly to connect and fix the three.

[0017] By adopting the above technical solution, when the oil storage tank is installed in the installation cavity, its bottom can be supported by the sponge block, and when vertical vibration occurs, the sponge block can release the vibration. In addition, the sponge block is relatively soft and can protect the bottom of the oil storage tank.

[0018] Optionally, the vertical frame includes a left vertical frame and a right vertical frame; the right vertical frame is provided with a binding strip that bypasses the oil storage tank and is connected to the left vertical frame to bind the oil storage tank to the vertical frame.

[0020] Optionally, a compression sponge is arranged between the vertical frame and the oil storage tank, and both ends of the compression sponge have penetration holes for the binding strip to pass through. The binding strip passes through one side of the compression sponge and passes through the oil storage tank and then passes through the other side of the compression sponge.

[0021] By adopting the above technical solution, when the binding strip presses the oil storage tank onto the vertical frame, the compression sponge can be pressed between the vertical frame and the oil storage tank, and the compression sponge can fill the gap between the vertical frame and the oil storage tank, thereby further improving the installation stability of the oil storage tank.

[0022] Optionally, the left vertical frame is provided with a locking assembly for locking one end of the binding strip, and the locking assembly includes a grille frame, and the grille frame is horizontally provided with a plurality of grille holes for the binding strip to pass through in an S-shape for locking.

[0023] By adopting the above technical solution, when one end of the tie strip is passed through in an S shape, the friction between the tie strip and the grid frame is relatively large, and the tie strip is not easy to be pulled out of the grid frame, so that the tie strip can always press the oil storage tank tightly on the vertical frame.

[0025] By adopting the above technical solution, a locking hole is penetrated through the locking plate and inserted into the grille hole. Due to the obstruction of the locking plate, the tie strip cannot be withdrawn from the grille frame, which further improves the locking of the end of the tie strip, so that the tie strip can always press the oil storage tank tightly on the vertical frame.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

After one pumping, when the drive device is controlled to pump the oil next time, the drive device does not need to pressurize the oil storage tank, but can directly pump out the hydraulic oil. Compared with the direct supply method in the prior art that requires long-term pressurization each time, the above system structure has higher operating efficiency;

[0028] When the hydraulic station vibrates laterally, the vertical frame can move slightly horizontally on the shock-absorbing bolts, and the shock-absorbing springs on both sides of the vertical frame can release the lateral vibration, so that the oil storage tank is not significantly affected by the vibration; when the hydraulic station vibrates longitudinally, the damping column can slide horizontally on the sliding rod, and under the action of the damping springs at both ends, the longitudinal vibration is released, and the damping springs on both sides of the damping column can always drive the damping column back to the middle of the moving chamber, so that the damping column always plays a shock-absorbing role;

[0039] When the energy storage hydraulic station is in operation, the control unit 3 drives the drive device 2 to pump oil into the oil storage tank 5, first fills the oil storage tank 5 with hydraulic oil and pressurizes it to a predetermined pressure, and then opens the valve device 4 to supply the hydraulic oil to the external actuator. After completing one execution, when the energy storage hydraulic station is in operation for the next time, the drive device 2 does not need to pressurize the oil storage tank 5. The drive device 2 can directly pump the pressurized hydraulic oil to the valve device 4 through the oil storage tank 5, thereby improving the working efficiency of the hydraulic station.

[0043] The top edge of the oil tank 1 has a mounting vertical bar 11 in the circumference, and the mounting vertical bar 11 is vertically arranged. When the mounting frame 61 is installed on the oil tank 1, the mounting vertical bar 11 is vertically inserted into the mounting groove 6121 of the mounting cross frame 612, and the connecting bolt 6122 passes through the mounting vertical bar 11, so that the mounting frame 61 is pre-fixed on the side wall of the oil tank 1.

[0044] Reference Figure 1 and Figure 2 The hydraulic station will vibrate during operation, and the shock absorbing mechanism 62 is used to absorb the shock of the oil storage tank 5 installed on the mounting frame 61, so that the installation of the oil storage tank 5 is more stable and the connection between the oil storage tank 5 and the driving device 2 and the valve device 4 is more firm and not prone to oil leakage.

[0045] The shock absorbing mechanism 62 includes a lateral shock absorbing component 621 and a longitudinal shock absorbing component 622, wherein the lateral shock absorbing component 621 is used to release the lateral vibration generated by the hydraulic station, and the longitudinal shock absorbing component 622 is used to release the longitudinal vibration generated by the hydraulic station.

[0046] The lateral shock absorbing assembly 621 is arranged on the vertical frame 611, and the left vertical frame 6111 and the right vertical frame 6112 both have symmetrical lateral shock absorbing assemblies 621. The lateral shock absorbing assembly 621 includes a shock absorbing bolt 6211 and a shock absorbing spring 6212. A mounting seat 12 having a threaded hole is welded and fixed to the side wall of the oil tank 1.

The sliding rod 6222 is horizontally passed through the two ends of the weight seat 6221 and passes through the moving chamber 6225. The damping column 6223 is located in the moving chamber 6225, and the damping column 6223 is sleeved on the sliding rod 6222 and can slide on the sliding rod 6222. There are two damping springs 6224, both of which are sleeved on the sliding rod 6222. One end of the damping spring 6224 is connected to the damping column 6223, and the other end is connected to the inner wall of the weight seat 6221. The damping spring 6224 drives the damping column 6223 to always be located in the middle of the moving chamber 6225. When longitudinal vibration occurs, the damping column 6223 can slide on the sliding rod 6222 and make the damping spring 6224 expand and contract, thereby releasing the vibration.

[0048] There may be a plurality of longitudinal shock absorbing components 622, which are horizontally spaced and arranged at the bottom of the base frame 613. The longitudinal shock absorbing components 622 can also be used as counterweights to make the installation of the mounting frame 61 more stable.

The binding strip 632 extends from one side of the left vertical frame 6111 and goes around the side of the oil storage tank 5 away from the vertical frame 611 and is fixed to the right vertical frame 6112. The binding strip 632 presses the oil storage tank 5 against the vertical frame 611.

[0053] The compression sponge 633 is used to enhance the compression stability of the tie strip 632 on the oil storage tank 5. The compression sponge 633 is arranged between the vertical frame 611 and the oil storage tank 5. Both ends of the compression sponge 633 are provided with penetration holes 6331.
