Description

Technical Field

[0001] This utility model relates to the field of telescopic pole technology, and in particular to a novel telescopic pole. Background Technology

[0002] In various stages of industrial production, the operation of automated equipment, and the manufacturing and operation of precision machinery, specific drive devices are often needed to achieve precise linear motion output. This linear motion output is the key to completing a series of operations such as material handling, component assembly, and precision positioning. As a long-established and widely used linear drive device, the hydraulic telescopic rod has gained widespread recognition and application in specific application areas due to its significant characteristic of being able to output powerful thrust. Its unique structure and principle make it irreplaceable in occasions that require large thrust and a certain degree of precision.

[0003] The speed of existing hydraulic telescopic booms is affected by load changes during operation. When the load increases, the speed tends to decrease, which can cause some inconvenience in actual operation. Especially at low speeds, the viscosity of the hydraulic oil may change, causing the equipment to vibrate and affecting the stability and accuracy of operation. At high speeds, the speed is limited by the upper limit of the hydraulic pump flow, resulting in insufficient flexibility in speed adjustment and making it difficult to accurately control the speed according to actual needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of telescopic rod, which aims to improve the problem of insufficient smoothness of movement of existing telescopic rods during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel telescopic rod, comprising a sealing cylinder for supporting the telescopic rod; a storage cylinder for storing hydraulic oil; a drive mechanism for controlling the extension and retraction of the push rod; an auxiliary mechanism for protecting the drive mechanism; and a sealing mechanism for sealing the storage cylinder. The drive mechanism includes a hydraulic motor and a rotating shaft. The hydraulic motor drives the rotating shaft to rotate. A bevel gear is fixedly connected to the outer wall of the rotating shaft. A worm gear is rotatably connected inside the sealing cylinder. A bevel gear is fixedly connected to one side of the worm gear. The bevel gear meshes with the bevel gear. The sealing cylinder has a worm gear rotatably connected inside, with the worm meshing with the worm gear. A lead screw is fixedly connected inside the worm gear, and a push rod is threadedly connected to the outer wall of the lead screw. A sealing block is fixedly connected inside the sealing cylinder, and the push rod is slidably connected to the sealing block. The auxiliary mechanism includes a curved piston plate and a gear pump. The curved piston plate is fixedly connected to the bottom of the lead screw and slides along the internal cavity of the sealing cylinder. The gear pump is driven by a rotating shaft. The output end of the gear pump is fixedly connected to a first connecting pipe and a second connecting pipe. One side of the first connecting pipe is fixedly connected to the inside of the sealing cylinder, and one side of the second connecting pipe is fixedly connected to the inside of a storage cylinder.

[0006] Furthermore, the sealing mechanism includes a sealing plate disposed at the top of the storage cylinder.

[0007] Furthermore, the outer wall of the sealing cylinder is rotatably connected to a clamp, and the clamp has a second groove inside.

[0008] Furthermore, a slot is provided on the top of the storage cylinder.

[0009] Furthermore, a sealing ring is fixedly connected to the outer wall of the sealing sheet, and the sealing ring is in contact with the inner wall of the second slot.

[0014] 1. In this utility model, a hydraulic motor can synchronously drive a bevel gear one and a gear pump. The bevel gear one drives a worm wheel through a bevel gear two and a worm, causing the worm wheel to drive the lead screw to move linearly. At the same time, the gear pump controls the volume of hydraulic oil inside the sealed cylinder, thereby assisting the lead screw to move linearly through a curved piston plate. This solves the problem of insufficient smoothness of movement of the telescopic rod during operation and improves the stability of the telescopic rod in use.

[0015] 2. In this utility model, the storage cylinder can be opened and closed by the top cover, and the top cover is fixed to the top of the storage cylinder by the clamp.

[0023] 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.

[0024] Reference Figure 1-5 This utility model provides an embodiment of a novel telescopic rod, comprising: a sealing cylinder 1 for supporting the telescopic rod; a storage cylinder 4 for storing hydraulic oil; a drive mechanism for controlling the extension and retraction of a push rod 3; an auxiliary mechanism for protecting the drive mechanism; and a sealing mechanism for sealing the storage cylinder 4. The drive mechanism includes a hydraulic motor 6 and a rotating shaft 14. The hydraulic motor 6 drives the rotating shaft 14 to rotate. A bevel gear 7 is fixedly connected to the outer wall of the rotating shaft 14. A worm gear 9 is rotatably connected inside the sealing cylinder 1. A bevel gear 8 is fixedly connected to one side of the worm gear 9, and the bevel gear 8 meshes with the bevel gear 7. A worm gear 8 is rotatably connected inside the sealing cylinder 1. The worm gear 10 and worm 9 mesh with the worm gear 10. A lead screw 2 is fixedly connected inside the worm gear 10. A push rod 3 is threadedly connected to the outer wall of the lead screw 2. A sealing block 24 is fixedly connected inside the sealing cylinder 1. The push rod 3 and the sealing block 24 are slidably connected. The auxiliary mechanism includes a curved piston plate 23 and a gear pump 12. The curved piston plate 23 is fixedly connected to the bottom of the lead screw 2 and slides along the internal cavity of the sealing cylinder 1. The gear pump 12 is driven by a rotating shaft 14. A connecting pipe 11 and a connecting pipe 2 13 are fixedly connected to the output end of the gear pump 12. One side of the connecting pipe 11 is fixedly connected to the inside of the sealing cylinder 1, and one side of the connecting pipe 2 13 is fixedly connected to the inside of the storage cylinder 4.

[0025] Specifically, during the operation of the telescopic rod, the hydraulic motor 6 starts and drives the rotating shaft 14 to rotate. As the rotating shaft 14 rotates, the connected bevel gear 7 also rotates. The rotation of bevel gear 7, through the transmission action of bevel gear 8, further drives the worm 9 to rotate. The rotation of the worm 9 transmits power to the worm wheel 10, causing the worm wheel 10 to also start rotating. The rotation of the worm wheel 10 drives the lead screw 2 to move, while the curved piston plate 23 at the top of the lead screw 2 slides in the internal cavity of the sealed cylinder 1. Due to the special shape design of the curved piston plate 23, it can effectively limit the movement trajectory of the lead screw 2, ensuring that the worm wheel 10 can accurately control the linear movement of the lead screw 2, thereby realizing the telescopic function of the top rod 3. At the same time, when the rotating shaft 14 rotates, it also synchronously drives the gear pump 12. During the extension of the push rod 3, the gear pump 12 draws hydraulic oil from the storage cylinder 4 through the connecting pipe 13 and injects it into the cavity at the bottom of the curved piston plate 23 in the sealed cylinder 1. This high pressure of the hydraulic oil effectively supports the lead screw 2, preventing damage under significant external forces. When the push rod 3 needs to retract, the gear pump 12 reverses its movement, returning the hydraulic oil from the sealed cylinder 1 to the storage cylinder 4. The hydraulic oil inside the storage cylinder 4 can be replaced through the opening at its top to ensure normal system operation. When sealing the storage cylinder 4, the top cover 22 is placed over the opening at the top of the storage cylinder 4. A sealing sheet 19 is placed between the two, and the sealing ring 21 at the bottom of the sealing sheet 19 will be inserted into the pre-set slot 17 at the top opening of the storage cylinder 4. At the same time, the sealing ring 20 around the sealing sheet 19 will tightly wrap the storage cylinder 4 and the top cover 22 to ensure the sealing effect. After the sealing sheet 19 and the top cover 22 are installed in place, the clamp 5 on the sealing cylinder 1 will fix them. In addition, the sealing ring 20 will be inserted into the slot 18 opened in the inner wall of the clamp 5 to further enhance the sealing performance. Finally, the clamp 5 is tightly fixed in the appropriate position through the cooperation of the threaded post 15 and the nut 16 to ensure the sealing and stability of the entire system.

[0026] Working principle: When the telescopic rod is in operation, the hydraulic motor 6 drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the bevel gear 7 to rotate, which in turn drives the worm gear 9 through the transmission of the bevel gear 8. The rotation of the worm gear 9 drives the worm wheel 10 to rotate, which in turn drives the lead screw 2. The curved piston plate 23 at the top of the lead screw 2 slides within the cavity of the sealed cylinder 1. Due to the shape of the curved piston plate 23, the movement trajectory of the lead screw 2 is restricted, allowing the worm wheel 10 to control the linear movement of the lead screw 2, thereby achieving the extension and retraction of the top rod 3. Simultaneously, the rotation of the rotating shaft 14 drives the gear pump 12. When the top rod 3 extends, the gear pump 12 draws hydraulic oil from the storage cylinder 4 through the connecting pipe 13 and injects it into the cavity at the bottom of the curved piston plate 23 in the sealed cylinder 1, thus utilizing the pressure of the hydraulic oil... The screw 2 is strongly supported to prevent it from being damaged due to excessive force. When the push rod 3 retracts, the gear pump 12 will move in the opposite direction, thereby transporting the hydraulic oil inside the sealing cylinder 1 to the storage cylinder 4. The hydraulic oil inside the storage cylinder 4 can be replaced through the opening at the top of the storage cylinder 4. When sealing the storage cylinder 4, the top cover 22 can be placed over the opening at the top of the storage cylinder 4, and a sealing plate 19 can be placed between the two. The sealing ring 21 at the bottom of the sealing plate 19 will be inserted into the slot 17 opened at the top opening of the storage cylinder 4. At the same time, the sealing ring 20 around the sealing plate 19 will wrap around the storage cylinder 4 and the top cover 22. After the sealing plate 19 and the top cover 22 are placed, they will be fixed by the clamp 5 on the sealing cylinder 1, and the sealing ring 20 will be inserted into the slot 18 opened on the inner wall of the clamp 5, thereby further sealing. The clamp 5 is tightened and fixed by the threaded post 15 and the nut 16.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
