A pressure-resistant, high-load-bearing hydraulic cylinder

Abstract

This utility model discloses a pressure-resistant, high-load-bearing hydraulic cylinder, relating to the field of hydraulic cylinder technology. The pressure-resistant, high-load-bearing hydraulic cylinder includes a hydraulic cylinder with a support mechanism and a lifting mechanism on its outer wall. The support mechanism includes a support portion and a limiting portion. The support portion includes two connecting frames and two support plates, and the limiting portion includes two connecting brackets. The outer wall of the hydraulic cylinder is fixedly connected to the outer walls of the two connecting frames. The technical advantage is that the support mechanism, through the linkage structure of the connecting frames, moving blocks, and connecting rods, can adjust the position and angle of the support plates, increasing their contact area with the supporting surface. This effectively disperses the pressure on the hydraulic cylinder during operation, preventing deformation of the cylinder body due to excessive local stress, and enhancing the pressure resistance and stability of the hydraulic cylinder under high-pressure environments. Simultaneously, the sliding cooperation between the limiting rails and the connecting brackets restricts the movement trajectory of the support plates, preventing them from shifting under load.

Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically to a pressure-resistant, high-load-bearing hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It can convert hydraulic energy into mechanical energy to realize the linear reciprocating motion or oscillation of a mechanism, outputting force and speed. It is widely used in the hydraulic systems of various machines.

[0003] Existing hydraulic cylinders expand the contact area through auxiliary support structures, but most of these auxiliary support structures are fixed designs and cannot flexibly adjust the support range and angle according to the working conditions of different support surfaces, resulting in poor adaptability. Therefore, a pressure-resistant and high-load-bearing hydraulic cylinder is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pressure-resistant, high-load-bearing hydraulic cylinder, which solves the problem that most auxiliary support structures are fixed designs, making it impossible to flexibly adjust the support range and angle according to the working conditions of different support surfaces, resulting in poor adaptability.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a hydraulic cylinder, and the outer wall of the hydraulic cylinder is provided with a support mechanism and a lifting mechanism;

[0008] The supporting mechanism includes a supporting part and a limiting part;

[0009] The supporting part includes two connecting frames and two supporting plates, and the limiting part includes two connecting brackets;

[0010] The outer wall of the hydraulic cylinder is fixedly connected to the outer walls of the two connecting frames. Two moving blocks are slidably arranged on the inner sides of the two connecting frames. Two connecting rods are hinged to the inner sides of the two moving blocks. The outer walls of the two connecting rods are hinged to the outer walls of the two support plates.

[0011] Preferably, the lifting mechanism includes two expansion frames, and a fixed box is fixedly installed on the outer wall of the output end of the hydraulic cylinder. The two expansion frames extend through the outer wall of the fixed box to the inner side of the fixed box on the same side. The two expansion frames in the lifting mechanism expand outward, which increases the force-bearing area during lifting, reduces the load pressure per unit area, and increases the upper limit of the hydraulic cylinder's load capacity.

[0012] Preferably, a fixed frame is fixedly provided on the outer wall of the hydraulic cylinder, and a control frame is fixedly provided on the outer wall of each of the two moving blocks. The inner side of the control frame is slidably connected to the outer wall of the fixed frame, and a pressing screw is threaded through the outer wall of the control frame and extends to the inner side of the fixed frame. The locking structure of the control frame and the pressing screw can be quickly fixed after the support plate is adjusted to the correct position, which further improves the reliability of the overall structure.

[0013] Preferably, two guide rails are slidably provided on the inner sides of the two connecting frames, and the outer walls of the two guide rails are slidably connected to the inner sides of the two moving blocks, so that the two moving blocks will not detach from the two connecting frames when they move.

[0014] Preferably, the outer wall of the hydraulic cylinder is fixedly provided with a limiting rail, the outer wall of the limiting rail is slidably connected to the inner side of the two connecting frames respectively, and the outer walls of the two connecting frames are fixedly connected to the outer walls of the two support plates respectively. The limiting rail and the two connecting frames can prevent them from shifting when subjected to force, thereby further enhancing the support stability.

[0015] Preferably, an extrusion block is slidably provided through the inner side of the fixed box, extending to the outer wall of the fixed box. Two connecting plates are hinged to the bottom surface of the extrusion block. The two connecting plates are respectively hinged to the outer walls of the two expansion frames on one side near the two expansion frames. An elastic element is provided between the two expansion frames. The outer wall of the elastic element is fixedly connected to the outer walls of the two expansion frames. The elastic element provided between the expansion frames will generate a restoring elastic force after the lifting operation ends and the external force is removed, pulling the two expansion frames to retract inward.

[0016] (III) Beneficial Effects

[0017] This invention provides a pressure-resistant, high-load-bearing hydraulic cylinder. It has the following beneficial effects:

[0018] (I) This pressure-resistant, high-load-bearing hydraulic cylinder has a support mechanism that, through the linkage structure of the connecting frame, the moving block, and the connecting rod, can adjust the position and angle of the support plate, increase its contact area with the support surface, effectively disperse the pressure on the hydraulic cylinder during operation, prevent the cylinder body from deforming due to excessive local stress, and enhance the pressure resistance stability of the hydraulic cylinder under high pressure. At the same time, the sliding cooperation between the limit rail and the connecting frame restricts the movement trajectory of the support plate, preventing it from deviating when under force. The locking structure of the control frame and the extrusion screw can be quickly fixed after the support plate is adjusted to the correct position, further improving the reliability of the overall structure.

[0019] (II) The pressure-resistant, high-load-bearing hydraulic cylinder has a fixed box for the lifting mechanism that is fixedly connected to the output end of the hydraulic cylinder, providing a stable installation base for components such as the expansion frame. When the output end of the hydraulic cylinder extends to perform lifting operations, the extrusion block moves inward to the fixed box under the action of external force. Through the hinged connecting plate, it drives the two expansion frames to unfold outward, increasing the force-bearing area during lifting, reducing the load pressure per unit area, and increasing the upper limit of the hydraulic cylinder's load capacity. The elastic element set between the two expansion frames will generate a reset elastic force after the lifting operation ends and the external force is removed, pulling the two expansion frames to retract inward. Through the connecting plate, it drives the extrusion block to reset, ensuring the stability and reliability of the mechanism for repeated use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides a technical solution: including a hydraulic cylinder 1, wherein the outer wall of the hydraulic cylinder 1 is provided with a support mechanism 2 and a lifting mechanism 3;

[0028] Supporting body 2 includes a supporting section and a limiting section;

[0029] The supporting part includes two connecting frames 21 and two supporting plates 23, and the limiting part includes two connecting brackets 28;

[0030] The outer wall of the hydraulic cylinder 1 is fixedly connected to the outer walls of two connecting frames 21. Two moving blocks 27 are slidably arranged on the inner sides of the two connecting frames 21 respectively. Two connecting rods 22 are hinged on the inner sides of the two moving blocks 27 respectively. The outer walls of the two connecting rods 22 are hinged to the outer walls of the two support plates 23 respectively. A fixed frame 25 is fixedly arranged on the outer wall of the hydraulic cylinder 1. A control frame 24 is fixedly arranged on the outer walls of the two moving blocks 27 respectively. The inner side of the control frame 24 is slidably connected to the outer wall of the fixed frame 25. A pressing screw 210 is threaded through the outer wall of the control frame 24 and extends to the inner side of the fixed frame 25. Two guide rails 26 are slidably arranged on the inner sides of the two connecting frames 21 respectively. The outer walls of the two guide rails 26 are slidably connected to the inner sides of the two moving blocks 27 respectively. A limit rail 29 is fixedly arranged on the outer wall of the hydraulic cylinder 1. The outer walls of the limit rails 29 are slidably connected to the inner sides of the two connecting frames 28 respectively. The outer walls of the two connecting frames 28 are fixedly connected to the outer walls of the two support plates 23 respectively.

[0031] The lifting mechanism 3 includes two expansion frames 34. A fixed box 31 is fixedly installed on the outer wall of the output end of the hydraulic cylinder 1. The two expansion frames 34 extend through the outer wall of the fixed box 31 to the inner side of the fixed box 31 on one side. A pressing block 32 is slidably installed through the inner side of the fixed box 31 and extends to the outer wall of the fixed box 31. Two connecting plates 33 are hinged to the bottom surface of the pressing block 32. The two connecting plates 33 are respectively hinged to the outer wall of the two expansion frames 34 on one side. An elastic element 35 is provided between the two expansion frames 34. The outer wall of the elastic element 35 is fixedly connected to the outer wall of the two expansion frames 34 respectively.

[0032] When in use, the hydraulic cylinder 1 serves as the core power component, while the support mechanism 2 on its outer wall is used to enhance the stability and pressure resistance of the hydraulic cylinder during operation, and the lifting mechanism 3 at the output end is used to improve the load-bearing capacity.

[0033] The support mechanism 2 is fixed to the outer wall of the hydraulic cylinder 1 via the connecting frame 21. When the support range needs to be adjusted, the moving block 27 can slide along the guide rail 26 on the inner side of the connecting frame 21. The guide rail 26 ensures the linearity and stability of the movement of the moving block 27. When the moving block 27 moves, its hinged connecting rod 22 will drive the support plate 23 to move synchronously, realizing the adjustment of the contact angle or position between the support plate 23 and the support surface. By increasing the contact area between the support plate 23 and the support surface, the pressure on the hydraulic cylinder 1 can be distributed, and the pressure resistance performance can be improved. The connecting frame 28 is along the limiting rail 26 on the outer wall of the hydraulic cylinder 1. 9. The sliding mechanism and the fixed connection between the connecting frame 28 and the support plate 23 restrict the movement trajectory of the support plate 23, preventing it from shifting under force and further enhancing the support stability. After the position of the support plate 23 is adjusted, it can be fixed by the cooperation of the control frame 24 and the fixed frame 25: the control frame 24 moves synchronously with the moving block 27 and slides along the fixed frame 25. The compression screw 210 is rotated to press the inner wall of the fixed frame 25, and the position of the control frame 24 is locked by friction, thereby fixing the moving block 27 and the support plate 23, ensuring that the support mechanism remains stable under high pressure.

[0034] The fixed box 31 of the lifting mechanism 3 moves synchronously with the output end. When the output end of the hydraulic cylinder 1 extends to perform the lifting operation, the pressing block 32 moves inward toward the fixed box 31 under the action of external force. The two hinged connecting plates 33 drive the two expansion frames 34 to unfold outward. The expansion frames 34 penetrate the fixed box 31 and extend outward, thereby increasing the force-bearing area during lifting and improving the load-bearing capacity of the hydraulic cylinder.

[0035] When the lifting operation ends and the external force is removed, the elastic element 35 will generate a restoring force, which will pull the two expansion frames 34 to retract inward, and drive the compression block 32 to reset through the connecting plate 33, so that the lifting mechanism returns to its initial state for the next operation.
