Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic tipping cylinders, and particularly relates to a self-balancing and stable hydraulic tipping cylinder. Background Technique

[0002] In life, the degree of mechanization is getting higher and higher. Hydraulic cylinders are often used in the process of realizing mechanical automation. Hydraulic cylinders can convert hydraulic energy into mechanical energy for realizing the tipping of objects;

[0003] After retrieval, the existing patent (publication number: CN218226540U) discloses a tipping cylinder, which includes a cylinder body and a piston rod arranged in the cylinder body. A lifting lug for connecting an object is further arranged at the end of the piston rod, and a cooling device is also included. The cooling device includes a housing. The inventor found the following problems in the process of realizing the utility model:

[0004] The existing hydraulic tipping cylinders have the cylinder body burst and lose balance and stability because the piston rod and the cylinder body cannot bear the pressure of descending and retracting. And at the moment when the piston rod of the hydraulic tipping cylinder pushes, the cylinder body will bear the maximum pressure at this time, resulting in the inability of the cylinder body to be relieved due to excessive pressure extrusion, increasing the loss in the cylinder and reducing the service life;

[0005] Therefore, a self-balancing and stable hydraulic tipping cylinder is proposed for the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a self-balancing and stable hydraulic tipping cylinder to solve the problems proposed in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: A self-balancing and stable hydraulic tipping cylinder, which includes a hydraulic tipping cylinder, a pressure reducing mechanism and a fixing sleeve. The surface of the hydraulic tipping cylinder is attached with a fixing sleeve. The surface of the fixing sleeve is attached with a hoop member. Two groups of fixing rods penetrate through the inside of the fixing sleeve. A protection plate is arranged above the fixing rods. Two groups of pressure reducing mechanisms are attached to the surface of the protection plate. A fixing block is arranged above the two groups of pressure reducing mechanisms. A connecting head is communicated above the fixing block. A connecting rod is arranged below the fixing sleeve. A fixing steel plate is arranged below the connecting rod;

[0008] A buffer mechanism is attached below the fixing rod. A sealing layer is attached below the buffer mechanism. A pressure reducing air hole is arranged below the sealing layer. A knob is arranged on one side of the pressure reducing air hole.

[0009] Preferably, the hydraulic tipping cylinder includes a cylinder body and a piston rod. The piston rod is welded at the center of the fixing block. The cylinder body is arranged below the piston rod.

[0010] Preferably, the pressure reducing mechanism includes a guide plate, a spring and a damper. The surface of the fixed block is attached to the damper. There are two groups of guide plates above the damper, and a spring is arranged between the two groups of guide plates.

[0011] Preferably, connecting pieces are arranged on both sides of the hoop member, and a first bolt is arranged at the center of the connecting piece.

[0012] Preferably, a second bolt is arranged below the fixed steel plate.

[0013] Preferably, the buffer mechanism includes a compression spring and a guide rod. The compression spring is attached to the surface of the sealing layer, and guide rods are arranged on both sides of the compression spring.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. Compared with the existing technology, the self-balancing and stable hydraulic tilting cylinder distributes part of the pressure borne by the piston rod through the pressure reducing mechanism below the fixed block, reduces the pressure when the piston rod is pushed, prevents excessive internal pressure of the cylinder body, and prolongs the service life of the hydraulic tilting cylinder.

[0016] 2. Compared with the existing technology, when the piston rod of the self-balancing and stable hydraulic tilting cylinder descends and retracts, the descending speed is slowed down by the buffer mechanism and the sealing layer inside the fixed sleeve. The air pressure generated by the descent of the sealing layer in the sealed fixed sleeve will rebound to the fixed rod and the protection plate. At the same time, the air pressure will expand and contract the pressure reducing air hole through the adjustment knob to control the descending speed of the fixed rod. Because the buffer mechanism and the sealing layer distribute part of the pressure inside the fixed sleeve, it can be achieved that the inside of the hydraulic tilting cylinder will not bear the maximum pressure throughout the descent, protecting the quality and safety of the cylinder body and the piston rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0024] As shown in the attached Figures 1 to 2 A self-balancing and stable hydraulic tilting cylinder shown in the figure includes a hydraulic tilting cylinder 3, a decompression mechanism 4 and a fixed sleeve 11. The surface of the hydraulic tilting cylinder 3 is attached with a fixed sleeve 11. The surface of the fixed sleeve 11 is attached with a hoop member 6. Two groups of fixed rods 5 penetrate through the inside of the fixed sleeve 11. Above the fixed rods 5 is provided a protective plate 1. The surface of the protective plate 1 is attached with two groups of decompression mechanisms 4. Above the two groups of decompression mechanisms 4 is provided a fixed block 2. Above the fixed block 2 is communicated with a connecting head 9. Below the fixed sleeve 11 is provided a connecting rod 13. Below the connecting rod 13 is provided a fixed steel plate 12;

[0025] Below the fixed rod 5 is attached a buffer mechanism 17. Below the buffer mechanism 17 is attached a sealing layer 14. Below the sealing layer 14 is provided a decompression air hole 15. On one side of the decompression air hole 15 is provided a knob 16.

[0026] Among them: The hydraulic tilting cylinder 3 can apply an external force to an object for mechanical movement. The fixed sleeve 11 can fix the lower part of the internal fixed rod 5 to prevent deviation. With the assistance of the buffer mechanism 17 and the sealing layer 14, the fixed rod 5 improves the stability and balance of the hydraulic tilting cylinder 3. The hoop member 6 closely fits the fixed sleeve 11 on the surface of the hydraulic tilting cylinder 3. The protective plate 1 fixes the upper part of the fixed rod 5. The piston rod 32 penetrates through the center of the protective plate 1. The fixed block 2 is fixed on the surface of the piston rod 32. The pressure reduction mechanism 4 is fixed on the surface of the fixed block 2. The pressure reduction mechanism 4 reduces the pressure received by the hydraulic tilting cylinder 3. The connecting head 9 is used to form a movable connection with an object. The connecting rod 13 is fixed by the fixing steel plate 12, so that the fixed sleeve 11 bears the pressure received by the hydraulic tilting cylinder 3. The pressure reduction air hole 15 can reduce the pressure when the fixed rod 5 descends. The knob 16 can adjust the pressure reduction degree of the pressure reduction air hole 15. Embodiment 2

[0027] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 5 shown, and the details are described below:

[0028] As a preferred embodiment, the hydraulic tilting cylinder 3 includes a cylinder body 31 and a piston rod 32. The piston rod 32 is welded at the center of the fixed block 2. The cylinder body 31 is arranged below the piston rod 32. Further, relying on high-pressure hydraulic oil as the power source, by sending the hydraulic oil into the internal part of the cylinder body 31, a force for the piston rod 32 on the cylinder body to move up and down is generated.

[0029] As a preferred embodiment, the pressure reduction mechanism 4 includes a guide plate 41, a spring 42 and a damper 43. The surface of the fixed block 2 fits the damper 43. Two groups of guide plates 41 are arranged above the damper 43. A spring 42 is arranged between the two groups of guide plates 41. Further, the spring 42 bears the pressure, and the spring 42 fixes the direction of the rebound force through the guide plate 41 and the damper 43 to prevent the spring 42 from deviating.

[0030] As a preferred embodiment, connecting pieces 8 are arranged on both sides of the hoop member 6. A first bolt 7 is arranged at the center of the connecting piece 8. Further, the connecting piece 8 makes the hoop member 6 more stably locked. After the connecting pieces 8 overlap, the hoop member 6 is fixed by the first bolt 7.

[0031] As a preferred embodiment, a second bolt 10 is arranged below the fixing steel plate 12. Further, the connecting rod 13 and the fixing steel plate 12 are fixedly connected by the second bolt 10.

[0032] As a preferred embodiment, the buffer mechanism 17 includes a compression spring 171 and a guide rod 172. The compression spring 171 is attached to the surface of the sealing layer 14, and the guide rods 172 are arranged on both sides of the compression spring 171. Further, the compression spring 171 can withstand the pressure when it descends to the peak, and the guide rods 172 ensure that the rebound force of the compression spring 171 will not deviate.

[0033] The working process of the present utility model is as follows: First, after forming a connection with an object through the connector 9, the hydraulic tilting cylinder 3 pushes out the piston rod 32. The pressure reducing mechanism 4 relieves part of the pressure of the piston rod 32. While the piston rod 32 is being pushed out, it drives the protection plate 1 through its own protrusion. While the protection plate 1 is being pushed out, it drives the fixed rod 5 to be pulled out. When descending, part of the pressure when the piston rod 32 retracts is shared by the pressure reducing mechanism 4, and the air pressure generated by the descent of the sealing layer 14 at the end of the fixed rod 5 in the space sealed by the fixed sleeve 11 rebounds to the piston rod 32 to relieve the pressure. The knob 16 and the pressure reducing air hole 15 can adjust the air pressure generated by the descent. The buffer mechanism 17 can protect the fixed rod 5 from the pressure it bears at the pressure peak being buffered and absorbed, thereby protecting the fixed rod 5.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
