Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil pipe storage technology, specifically to a hydraulic oil pipe retraction and extension device. Background Technology

[0002] In fields such as engineering machinery and industrial hydraulic equipment, hydraulic hoses are core components for transmitting hydraulic energy, and their operation directly affects the operating efficiency and safety of the equipment. Hydraulic hoses typically have a certain length and weight, and require frequent connection, disassembly, and retraction.

[0003] Traditionally, hydraulic hoses are wound manually using a winding machine.

[0004] Traditional equipment requires manual retraction of the oil pipe after it is pulled out, and sometimes the oil pipe needs to be retracted and extended frequently. Due to the low efficiency of manual retraction and extension, the production progress is slow. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic hose retraction and extension device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A hydraulic hose retraction device includes a base, a housing is fixedly connected to the top of the base, a limit block is fixedly connected to the front of the housing, a through groove is formed on the surface of the limit block, and a hydraulic hose is provided inside the housing. It also includes a limiting mechanism, a fixing mechanism, and a retracting mechanism; The limiting mechanism is used to limit the hydraulic oil pipe; The fixing mechanism is used to fix the extension length of the hydraulic oil pipe; The winding mechanism is located inside the housing and is used to wind up the hydraulic hoses.

[0007] A further improvement of this utility model is that: the launching and retracting mechanism includes a base plate, which is rotatably connected to the top of the base. A rotating cylinder is fixedly connected to the top of the base plate, and a guide plate is fixedly connected to the surface of the rotating cylinder. The guide plate is spiral-shaped, and a hydraulic oil pipe is disposed inside the guide plate. A rotating oil chamber is fixedly connected to the top of the rotating cylinder, and the end of the hydraulic oil pipe extends into the interior of the rotating oil chamber. A sealed bearing is fixedly connected to the top axis of the rotating oil chamber, and an oil inlet pipe is fixedly connected inside the sealed bearing.

[0008] A further improvement of the present invention is that: a rotating shaft is fixedly connected inside the rotating cylinder, the rotating shaft passes through the base plate and extends into the interior of the base, a spiral spring is fixedly connected to the surface of the rotating shaft, and the end of the spiral spring is fixedly connected to the surface of the base.

[0009] A further improvement of the present invention is that the limiting mechanism includes a fixed frame, which is fixedly connected to the top of the base and is located on the front side of the limiting block. Rollers are rotatably connected to the upper and lower sides inside the fixed frame, and a hydraulic oil pipe is rotatably connected to the middle of the two rollers.

[0010] A further improvement of the present invention is that the fixing mechanism includes a mounting frame, which is fixedly connected to the top of the base. A lower clamping block is fixedly connected inside the mounting frame, and a screw is threadedly connected inside the mounting frame. An upper clamping block is rotatably connected to the end of the screw.

[0011] A further improvement of this utility model is that the surfaces of the upper clamping block, the lower clamping block, and the roller are covered with rubber.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model provides a hydraulic oil pipe winding and unwinding device. By pulling out the hydraulic oil pipe, the rotating drum is driven to rotate, compressing the spiral spring to store energy. After use, the spiral spring rebounds and drives the rotating drum to rotate in the opposite direction to wind up the oil pipe, realizing fully automatic winding, shortening operation time and reducing the labor intensity of operators. At the same time, the guide plates on both sides of the oil pipe winding and unwinding path form a clamping and guiding channel through the rollers, which restricts the lateral deviation of the oil pipe and guides its smooth movement, avoiding twisting and knotting, ensuring stable hydraulic oil delivery, and reducing equipment failure.

[0013] 2. This utility model provides a hydraulic hose retraction device, which drives the upper and lower clamping blocks to clamp and fix the hose by rotating the screw. The self-locking function of the thread is used to clamp the hose and prevent it from retracting automatically, thereby adapting to the needs of multiple lengths and improving the safety and flexibility of use.

[0014] 3. This utility model provides a hydraulic oil pipe retraction and deployment device. By covering the surface of the roller and the upper and lower clamping blocks with a rubber layer, direct contact between the metal and the oil pipe is avoided, thereby reducing scratches and wear, extending the service life of the oil pipe, and reducing maintenance costs.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0020] Example 1 This utility model provides a hydraulic oil pipe retraction and extension device, including a base 11, a housing 12 fixedly connected to the top of the base 11, a limiting block 13 fixedly connected to the front of the housing 12, a through groove opened on the surface of the limiting block 13, and a hydraulic oil pipe 21 arranged inside the housing 12. It also includes a limiting mechanism 3, a fixing mechanism 4, and a retracting mechanism 5; The limiting mechanism 3 is used to limit the hydraulic oil pipe 21; The fixing mechanism 4 is used to fix the extension length of the hydraulic oil pipe 21; The winding mechanism 5 is located inside the housing 12 and is used to wind up the hydraulic oil pipe 21.

[0021] In this embodiment, as Figure 1 As shown, the hydraulic hose 21 is first pulled out from the inside of the retracting mechanism 5. When it extends to the required length, the extension length is fixed by the fixing mechanism 4. During the pulling process, the retracting mechanism 5 can ensure the smooth movement of the hose.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a take-up and release mechanism 5 and a limiting mechanism 3; Preferably, the launching and retracting mechanism 5 includes a base plate 51, which is rotatably connected to the top of the base 11. A rotating cylinder 52 is fixedly connected to the top of the base plate 51. A guide plate 53 is fixedly connected to the surface of the rotating cylinder 52. The guide plate 53 is spiral-shaped. A hydraulic oil pipe 21 is disposed inside the guide plate 53. A rotating oil chamber 54 is fixedly connected to the top of the rotating cylinder 52. The end of the hydraulic oil pipe 21 extends into the interior of the rotating oil chamber 54. A sealed bearing 57 is fixedly connected at the top axis of the rotating oil chamber 54. An oil inlet pipe 58 is fixedly connected inside the sealed bearing 57.

[0023] A rotating shaft 55 is fixedly connected inside the rotating cylinder 52. The rotating shaft 55 passes through the base plate 51 and extends into the interior of the base 11. A spiral spring 56 is fixedly connected to the surface of the rotating shaft 55. The end of the spiral spring 56 is fixedly connected to the surface of the base 11.

[0024] The limiting mechanism 3 includes a fixed frame 31, which is fixedly connected to the top of the base 11. The fixed frame 31 is located on the front side of the limiting block 13. Rollers 32 are rotatably connected to the upper and lower sides inside the fixed frame 31, and a hydraulic oil pipe 21 is rotatably connected to the middle of the two rollers 32.

[0025] In this embodiment, as Figure 2-5 As shown, by pulling the hydraulic oil pipe 21 out from the base 11, the hydraulic oil pipe 21 is pulled out and at the same time, it drives the rotating drum 52 on the base plate 51 to rotate inside the base 11. At the same time, it is driven by the rotating shaft 55, thereby compressing the spiral spring 56. At this time, the hydraulic oil pipe 21 is released along the spiral channel of the guide plate 53, and then hydraulic oil is injected into the rotating oil chamber 54 through the oil inlet pipe 58. The hydraulic oil is transported through the hydraulic oil pipe 21. After use, the spiral spring 56 rebounds, thereby driving the rotating shaft 55 to rotate in the opposite direction, and then the hydraulic oil pipe 21 is wound into the inside of the guide plate 53, thereby realizing automatic winding. During the winding and extension process, the hydraulic oil pipe 21 is clamped by the roller 32, thereby ensuring the smoothness of the hydraulic oil pipe 21 transportation.

[0026] Example 3 The difference from Embodiment 2 is that this embodiment discloses a fixing mechanism 4; Preferably, the fixing mechanism 4 includes a mounting frame 41, which is fixedly connected to the top of the base 11. A lower clamping block 42 is fixedly connected inside the mounting frame 41, and a screw 44 is threadedly connected inside the mounting frame 41. An upper clamping block 43 is rotatably connected to the end of the screw 44.

[0027] The surfaces of the upper clamping block 43, the lower clamping block 42, and the roller 32 are covered with rubber.

[0028] In this embodiment, as Figure 2 As shown, when it extends to the specified length, the upper clamping block 43 moves downward by rotating the screw 44, thereby clamping and fixing the hydraulic oil pipe 21 and preventing it from automatically retracting into the base 11. By covering the surfaces of the roller 32, the lower clamping block 42 and the upper clamping block 43 with a layer of rubber, the hydraulic oil pipe 21 can be prevented from being scratched during movement, thereby increasing the service life of the hydraulic oil pipe 21.

[0029] The working principle of this utility model is as follows: First, the hydraulic hose 21 is pulled out from inside the base 11. As the hydraulic hose 21 is pulled out, it drives the rotating drum 52 on the base plate 51 to rotate inside the base 11. Simultaneously, this rotation is transmitted through the rotating shaft 55, thereby compressing the spiral spring 56. At this time, the hydraulic hose 21... The hydraulic oil is released along the spiral channel of the guide plate 53 and then injected into the rotating oil chamber 54 through the oil inlet pipe 58. The hydraulic oil is transported through the hydraulic oil pipe 21. After use, the spiral spring 56 rebounds, thereby driving the rotating shaft 55 to rotate in the opposite direction, and then the hydraulic oil pipe 21 is wound into the interior of the guide plate 53, thereby realizing automatic winding. During the winding and extension process, the hydraulic oil pipe 21 is clamped by the roller 32, thereby ensuring the smooth transport of the hydraulic oil pipe 21. When it extends to the specified length, the upper clamping block 43 is moved downward by rotating the screw 44, thereby clamping and fixing the hydraulic oil pipe 21 and preventing it from automatically retracting into the base 11. By covering the surface of the roller 32, the lower clamping block 42 and the upper clamping block 43 with a layer of rubber, the hydraulic oil pipe 21 can be prevented from being scratched during the movement, thereby improving the service life of the hydraulic oil pipe 21.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
