Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a mechanical locking hydraulic cylinder with auxiliary fixing function. Background Technology

[0002] Hydraulic cylinders are widely used in many industrial fields such as construction machinery, mining machinery, and metallurgical equipment. They mainly convert hydraulic energy into mechanical energy to achieve linear reciprocating motion, thereby driving working parts to complete various operations. In some specific working conditions, such as the lifting of aerial work platforms and the extension and fixing of crane booms, after the hydraulic cylinder drives the working parts to the designated position, it is necessary to maintain the stability of its position to ensure operational safety and accuracy.

[0003] The applicant found through a search that a Chinese patent discloses "a hydraulic cylinder with mechanical locking function", with publication (announcement) number "CN210397315U". This patent mainly improves the device, adds the cylinder locking function, and makes it more convenient to replace the cylinder later. However, the existing hydraulic cylinder has poor stability, is not convenient for auxiliary fixation, and will vibrate during operation, resulting in insufficient stability. Therefore, we propose a mechanical locking hydraulic cylinder with auxiliary fixation function. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical locking hydraulic cylinder with auxiliary fixing function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical locking hydraulic cylinder with auxiliary fixing function, comprising a load-bearing plate, a cylinder and a fixing assembly, wherein the fixing assembly includes a motor and a connecting slide plate, the motor is connected to a bidirectional threaded rod via a transmission rod, the bidirectional threaded rod is connected to a support block via a sliding support rod, the support block is connected to a support plate via a first spring, and the support plate is connected to a clamping plate via a screw rod.

[0006] As a preferred embodiment, two baffles are fixedly connected to the surface of the load-bearing plate, and a placement block is fixedly connected to the corresponding side of the two baffles. The fixing component and the protective component are both set on the surface of the load-bearing plate, and the hydraulic cylinder is set inside the protective component.

[0007] As a preferred embodiment, the bottom of the motor is fixedly installed on one side of the surface of the load-bearing plate, one end of the transmission rod is fixedly connected to the output end of the motor, one end of the bidirectional threaded rod is fixedly connected to the other end of the transmission rod, the internal thread below the sliding support rod is connected to the circumferential surface of the bidirectional threaded rod, the bottom of the support block is fixedly connected to the top of the sliding support rod, and two sets of connecting slide plates are provided, with the corresponding sides of the two sets of connecting slide plates fixedly connected to both sides of the support block.

[0008] As a preferred embodiment, the first spring is sleeved on the outer wall of the support block, one side of the support plate is fixedly connected to one end of the support block, the screw rod is threadedly connected to the support plate, and one end of the clamping plate is rotatably connected to one end of the screw rod.

[0009] As a preferred embodiment, the protective component includes a fixing plate, one end of which is fixedly connected to a first arc-shaped plate, both ends of the inner wall of the first arc-shaped plate are fixedly connected to connecting blocks, and a connecting rod is fixedly connected to the corresponding side of each connecting block.

[0010] As a preferred embodiment, the connecting rod is fixedly connected to two ends near the connecting block with a second spring, and the other end of the second spring is fixedly connected to a slider. The slider is connected to a pad through a connecting shaft. The slider is rotatably connected to the connecting shaft, and the connecting shaft is rotatably connected to the pad. A second arc-shaped plate is fixedly connected to one side of the pad, and the outer walls of the oil cylinder and the second arc-shaped plate abut against each other.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. With the fixed components in place, when the motor is started, the output end of the motor drives the transmission rod to rotate, and the transmission rod drives the double-threaded rod at one end to rotate. The sliding support rod moves linearly on the surface of the double-threaded rod. As the double-threaded rod rotates, the sliding support rod will move towards or away from each other along the axial direction of the double-threaded rod. When it moves to the appropriate position, the distance between the clamping plates can be adjusted by rotating the screw rod. This can adapt to the fixing requirements of parts of different sizes and shapes, thereby fixing the hydraulic cylinder and ensuring its stability.

[0013] 2. With the protective components in place, when an object hits the second arc plate, the second arc plate will cause the pad to squeeze the slider. The slider slides along the connecting rod and compresses the second spring. The second spring absorbs the impact energy through elastic deformation, thereby reducing the impact force transmitted to the cylinder body, reducing the risk of damage to the cylinder due to collisions, vibrations and other external forces, and extending the service life of the cylinder.

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.

[0022] Example 1:

[0023] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4A mechanical locking hydraulic cylinder with auxiliary fixing function includes a load-bearing plate 1, a cylinder 2, and a fixing assembly 3. The fixing assembly 3 includes a motor 301 and a connecting slide plate 306. The motor 301 is connected to a bidirectional threaded rod 303 via a transmission rod 302. The bidirectional threaded rod 303 is connected to a support block 305 via a sliding support rod 304. The support block 305 is connected to a support plate 308 via a first spring 307. The support plate 308 is connected to a clamping plate 310 via a screw rod 309. Two baffles 5 are fixedly connected to the surface of the load-bearing plate 1. A placement block 6 is fixedly connected to the corresponding side of the two baffles 5. The fixing assembly 3 and the protective assembly 4 are both disposed on the surface of the load-bearing plate 1. The cylinder 2 is disposed inside the protective assembly 4. The bottom of the motor 301 is fixedly mounted on a... Mounted on one side of the surface of the load-bearing plate 1, one end of the transmission rod 302 is fixedly connected to the output end of the motor 301, one end of the bidirectional threaded rod 303 is fixedly connected to the other end of the transmission rod 302, the internal thread below the sliding support rod 304 is connected to the circumferential surface of the bidirectional threaded rod 303, the bottom of the support block 305 is fixedly connected to the top of the sliding support rod 304, two sets of connecting slide plates 306 are provided, and the corresponding sides of the two sets of connecting slide plates 306 are fixedly connected to the two sides of the support block 305, the first spring 307 is sleeved on the outer wall of the support block 305, one side of the support plate 308 is fixedly connected to one end of the support block 305, the screw rod 309 is threadedly connected to the support plate 308, and one end of the clamping plate 310 is rotatably connected to one end of the screw rod 309.

[0024] The surface of the load-bearing plate 1 is provided with a groove that matches the connecting slide plate 306, allowing the bottom of the connecting slide plate 306 to slide inside the load-bearing plate 1, thereby increasing the stability of the fixing component 3. The inside of the baffle 5 is provided with a rotating hole that matches the bidirectional threaded rod 303, thereby facilitating the movement of the bidirectional threaded rod 303 inside. The end of the bidirectional threaded rod 303 away from the motor 301 is rotatably connected to an anti-detachment block, which is located on the outside of the baffle 5. The anti-detachment block serves to support the movement of the bidirectional threaded rod 303. The surface of the support block 305 is provided with a hole that matches the screw rod 309. The bidirectional threaded rod 303 is located inside the placement block 6, and the inside of the placement block 6 is provided with a groove to facilitate the movement of the bidirectional threaded rod 303. The other end of the screw rod 309 is fixedly connected to a handle, which can be used to fix one end of the hydraulic cylinder 2.

[0025] Specifically, after the motor 301 starts, its output end drives the transmission rod 302 to rotate, which in turn drives the connected bidirectional threaded rod 303 to rotate, causing the sliding support rod 304 to move linearly on the surface of the bidirectional threaded rod 303, realizing axial movement towards or away from each other. When the sliding support rod 304 moves to a suitable position, the screw rod 309 is rotated to adjust the spacing of the clamping plate 310, thereby fixing the oil cylinder 2 and ensuring its stability.

[0026] Example 2:

[0027] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6 Furthermore, based on Embodiment 1, the protective component 4 includes a fixing plate 401. One end of the fixing plate 401 is fixedly connected to a first arc-shaped plate 402. Both ends of the inner wall of the first arc-shaped plate 402 are fixedly connected to connecting blocks 403. A connecting rod 404 is fixedly connected to the corresponding side of the connecting block 403. A second spring 405 is fixedly connected to both ends of the connecting rod 404 near the connecting block 403. A slider 406 is fixedly connected to the other end of the second spring 405. A pad 408 is connected to the slider 406 through a connecting shaft 407. The slider 406 is rotatably connected to the connecting shaft 407. The connecting shaft 407 is rotatably connected to the pad 408. A second arc-shaped plate 409 is fixedly connected to one side of the pad 408. The outer walls of the oil cylinder 2 and the second arc-shaped plate 409 abut against each other.

[0028] The two ends of the connecting shaft 407 can be compressed on the slider 406 and the pad 408 according to the size of the oil cylinder 2, thereby protecting the oil cylinder 2.

[0029] Specifically, when an object impacts the second arc-shaped plate 409, the second arc-shaped plate 409 causes the pad 408 to press against the slider 406. The slider 406 slides along the connecting rod 404 and compresses the second spring 405. The second spring 405 absorbs energy through elastic deformation, reducing the impact force transmitted to the cylinder 2 body, reducing the risk of damage to the cylinder 2 due to collision and vibration, and extending its service life.

[0030] Working principle of this utility model: This utility model is a mechanical locking hydraulic cylinder 2 with auxiliary fixing function. After the motor 301 is started, the output end drives the transmission rod 302 to rotate, which in turn drives the bidirectional threaded rod 303 to rotate in the rotating hole of the baffle 5. One end is supported by the anti-detachment block. The rotating bidirectional threaded rod 303 causes the threaded sliding support rod 304 to move linearly in the slide groove of the load-bearing plate 1. When the sliding support rod 304 reaches the appropriate position, the screw rod 309, which is threadedly connected to the support plate 308 and has a clamping plate 310, is rotated to adjust the distance to fix the cylinder 2. During this process, the distance between the support block 305 and the support plate 308 is adjusted. The first spring 307 acts as a buffer, adapting to certain dimensional deviations and vibrations, enhancing stability and reliability. When an object impacts the second arc-shaped plate 409, the connecting shaft 407 can be compressed according to the size of the cylinder 2. The second arc-shaped plate 409 pushes the pad 408 to squeeze the slider 406. The slider 406 slides along the connecting rod 404 and compresses the second spring 405. The second spring 405 absorbs the impact energy through elastic deformation, reducing the impact force transmitted to the cylinder 2 body, reducing the risk of damage due to collision and vibration, extending the life of the cylinder 2, and providing all-round protection for the cylinder 2 under complex working conditions, ensuring its safe and stable operation.
