[0002] Top-mounted horizontal hydraulic power units are a common type of hydraulic power device. Their main components include a hydraulic pump, electric motor, oil tank, hydraulic valves, hydraulic cylinders, and a control system, and they are widely used in various industrial fields. Their main feature is that the hydraulic pump and electric motor are combined and installed as a whole on top of the hydraulic power unit, thus saving space and improving installation convenience.

[0003] In the prior art, the hydraulic oil tank of the top-mounted horizontal hydraulic station is generally made of metal. Since the working environment of the hydraulic station is often harsh, it is easily corroded by chemical substances in the environment and eroded by rainwater, which makes the hydraulic oil tank easy to corrode and shorten its service life. Therefore, we propose a corrosion-resistant top-mounted horizontal hydraulic station. Utility Model Content

This utility model is convenient to use, easy to operate, has good stability, and high reliability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a hydraulic oil tank, with an electric motor, hydraulic valve, and hydraulic cylinder installed at the top of the hydraulic oil tank. A metal protective block is provided on the outer wall of the hydraulic oil tank, and a protective cover is welded to the outer wall of the hydraulic oil tank outside the metal protective block. An extrusion plate is provided on one side inside the protective cover, and baffles are provided at the top and bottom of the extrusion plate. A handle is provided on the outer side of the protective cover, and two push rods are fixed to the surface of the handle. The push rods pass through through holes in the outer wall of the protective cover and are fixedly connected to the extrusion plate. A spring is installed at the outer end of the push rod, and the spring is located between the inner wall of the protective cover and the extrusion plate. A limit block is provided on the inner wall of the top of the protective cover, and a first elastic pressure plate and a second elastic pressure plate are welded to both sides of the bottom end of the limit block.

[0006] Furthermore, the top of the hydraulic oil tank is welded with lifting lugs, and there are four lifting lugs in total, which are distributed at the corner positions of the top of the hydraulic oil tank.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1-2 This utility model provides a corrosion-resistant, top-mounted horizontal hydraulic station technical solution: including a hydraulic oil tank 1, an electric motor 2, a hydraulic valve 3, and a hydraulic cylinder 4 installed at the top of the hydraulic oil tank 1, a metal protective block 6 provided on the outer wall of the hydraulic oil tank 1, a protective cover 10 welded on the outer wall of the hydraulic oil tank 1 outside the metal protective block 6, an extrusion plate 11 provided on one side inside the protective cover 10, and baffles 20 provided at the top and bottom of the extrusion plate 11;

[0022] Specifically, the metal protective block 6 is installed on the outer surface of the hydraulic oil tank 1. The metal protective block 6 is in close contact with the hydraulic oil tank 1 through the connecting support 7. The metal protective block 6 is made of zinc alloy. By using the sacrificial anode protection method, the metal protective block 6 with strong reducing properties is used as the protective electrode and connected to the hydraulic oil tank 1 to form a galvanic cell. The metal protective block 6, as the negative electrode, undergoes an oxidation reaction and is consumed. The hydraulic oil tank 1, as the positive electrode, can slow down corrosion. The metal protective blocks 6 are evenly distributed on the outer surface of the hydraulic oil tank 1 to ensure uniform current distribution. By effectively utilizing the sacrificial anode protection of the hydraulic oil tank 1 of the top-mounted horizontal hydraulic station, the corrosion of the hydraulic oil tank 1 can be slowed down and its service life extended.

[0023] A handle 14 is provided on the outer side of the protective cover 10, and two push rods 12 are fixed on the surface of the handle 14. The push rods 12 pass through the through hole 15 on the outer wall of the protective cover 10 and are fixedly connected to the extrusion plate 11. A spring 13 is installed on the outer end of the push rod 12 and the spring 13 is located between the inner wall of the protective cover 10 and the extrusion plate 11. A hollow protective ring 16 is slidably sleeved on the outer wall of the push rod 12. The hollow protective ring 16 has external threads on the outside and internal threads in the through hole 15. The hollow protective ring 16 is threaded inside the through hole 15. A limit block 17 is provided on the inner wall of the top of the protective cover 10, and a first elastic pressure plate 18 and a second elastic pressure plate 19 are welded on both sides of the bottom end of the limit block 17.

[0024] When installing the metal protective block 6, first pull the handle 14 to make the push rod 12 move the pressing plate 11 horizontally. At this time, the push rod 12 moves outward to press the spring 13. Then, the metal protective block 6 is pushed into the protective cover 10 from below. The limiting block 17 limits the metal protective block 6. Then release the handle 14 so that the push rod 12 pushes the pressing plate 11 under the elastic force of the spring 13 to lock the metal protective block 6. The pressing plate 11 limits the metal protective block 6 through the stop edge 20.

[0025] Please see Figure 3-5 The top of the hydraulic oil tank 1 is welded with lifting lugs 5, and there are four lifting lugs 5 distributed at the corners of the top of the hydraulic oil tank 1. The lifting lugs 5 facilitate the movement of the upper horizontal hydraulic station by hoisting.

[0026] The metal protective block 6 is made of zinc alloy and has a regular cuboid structure. Connecting feet 7 are provided on both sides of the metal protective block 6. The surface of the connecting feet 7 is provided with a first pressing end face 71 and a second pressing end face 72, and the second pressing end face 72 is tightly fitted to the outer surface of the hydraulic oil tank 1. The end face of the connecting feet 7 near the hydraulic oil tank 1 is provided with a snap-fit ​​protrusion 8, and a snap-fit ​​groove 9 is provided on the outer wall of the hydraulic oil tank 1 at the position of the snap-fit ​​protrusion 8, and the snap-fit ​​protrusion 8 and the snap-fit ​​groove 9 are tightly engaged.

[0027] Furthermore, the connecting legs 7 on both sides of the metal protective block 6 are inserted into the inner side of the first elastic pressure plate 18 and the second elastic pressure plate 19 at the bottom of the limiting block 17. The first elastic pressure plate 18 and the second elastic pressure plate 19 respectively press and fit the first pressing end face 71 and the second pressing end face 72 of the connecting leg 7, so that the second pressing end face 72 is tightly fitted with the outer surface of the hydraulic oil tank 1. The snap-fit ​​protrusion 8 is snapped into the snap-fit ​​groove 9 on the outer surface of the hydraulic oil tank 1, which not only increases the contact area between the connecting leg 7 and the hydraulic oil tank 1, but also prevents the metal protective block 6 from loosening. The metal protective block 6 is installed on the hydraulic oil tank 1 by snap-fit, which is convenient for installation and easy for the metal protective block 6 to be disassembled and replaced.

[0028] The protective cover 10 has an opening at the lower end, and the surface of the protective cover 10 is coated with anti-rust paint;

[0029] The protective cover 10 can protect the metal protective block 6 from rain and dust, extend its service life, and reduce the number of replacements.

[0030] Detailed implementation: First, a metal protective block 6 is installed on the outer surface of the hydraulic oil tank 1. The metal protective block 6 is in close contact with the hydraulic oil tank 1 via connecting legs 7. The metal protective block 6 is made of zinc alloy, which is based on the principle of sacrificial anode protection. In the sacrificial anode protection system, because zinc alloy has strong reducing properties, the metal protective block 6 is used as the sacrificial anode (protective electrode) and is tightly connected to the hydraulic oil tank 1 of the upper-mounted horizontal hydraulic station via connecting legs 7, thus forming a complete galvanic cell circuit.

[0031] In this galvanic cell, the metal protective block 6, acting as the negative electrode, preferentially undergoes oxidation and is gradually consumed over time. Meanwhile, the hydraulic oil tank 1, acting as the positive electrode, has its surface oxidation suppressed by the galvanic cell, thus effectively slowing down the corrosion rate.

[0032] Furthermore, to ensure the protection effect, multiple metal protective blocks 6 (only one is shown in the figure) can be installed on the outside of the hydraulic oil tank 1. The metal protective blocks 6 are evenly distributed on the outer surface of the hydraulic oil tank 1. This distribution method can ensure that the current is evenly distributed on the surface of the hydraulic oil tank 1, avoiding local insufficient protection or over-protection. By using the sacrificial anode protection method in this scientific and reasonable way, the service life of the hydraulic oil tank 1 in the top-mounted horizontal hydraulic station can be significantly extended, and the maintenance costs and equipment failure risks caused by corrosion can be reduced.

[0033] When installing the metal protective block 6, first pull the handle 14 to cause the push rod 12 to move the pressing plate 11 horizontally, pushing the metal protective block 6 into the protective cover 10 from below. The limiting block 17 limits the metal protective block 6. Then release the handle 14 so that the push rod 12, under the elastic action of the spring 13, pushes the pressing plate 11 to lock the metal protective block 6. The pressing plate 11 fixes the metal protective block 6 through the stop 20. The connecting feet 7 on both sides of the metal protective block 6 are inserted into the inner side of the first elastic pressure plate 18 and the second elastic pressure plate 19 at the bottom of the limiting block 17. The first elastic pressure plate 18 and the second elastic pressure plate 19 are separated. Do not press and fit the first crimping end face 71 and the second crimping end face 72 of the connecting leg 7 together, so that the second crimping end face 72 is tightly fitted to the outer surface of the hydraulic oil tank 1. The snap-fit ​​protrusion 8 is snapped into the snap-fit ​​groove 9 on the outer surface of the hydraulic oil tank 1. This not only increases the contact area between the connecting leg 7 and the hydraulic oil tank 1, but also prevents the metal protective block 6 from loosening. The metal protective block 6 is installed on the hydraulic oil tank 1 by snap-fit, which is convenient for installation and easy to disassemble and replace. The protective cover 10 can protect the metal protective block 6 from rain and dust, extend its service life and reduce the number of replacements.
