Description

Technical Field

[0001] This utility model relates to the field of tippler technology, and in particular to a hydraulic system for stabilizing the chassis of a tippler. Background Technology

[0002] The hydraulic system of the tippler stabilizes the chassis, which is the core functional unit that ensures safety and stability during tippler operation. Relying on the controllable power provided by the hydraulic system, it dynamically adjusts the chassis's support force and balance during the tippler's tilting process to adapt to carts of different weights and center of gravity distributions, effectively suppressing the impact and vibration generated during tilting and preventing the equipment from overturning or shifting.

[0003] The existing tippler hydraulic system stabilizes the chassis, but the disassembly and maintenance of the hydraulic cylinders are extremely inconvenient. Traditional methods often require a lot of manpower and time, using complex tools, which is not only inefficient but may also damage components due to improper operation, increasing maintenance costs. At the same time, the connecting pin area lacks an effective cleaning mechanism. In actual operation, dust and impurities easily accumulate in this area, leading to poor connection, jamming, and even accelerated pin wear. This seriously affects the normal operation of the hydraulic system stabilizing the chassis, reducing the reliability and safety of the tippler operation. Utility Model Content

[0007] Preferably, in order to move the movable threaded block by controlling the rotation of the miniature threaded rod, thereby driving the connecting pin to move via the bending plate, the miniature threaded rod is rotatably inserted into the extension seat, the movable threaded block is threaded onto the miniature threaded rod, the connecting pin is fixedly connected to the movable threaded block via the bending plate, and one end of the miniature threaded rod is connected to the transmission connection assembly.

[0008] Preferably, in order to enable the micro threaded rod to rotate by controlling the micro motor to turn on, the micro motor is fixedly mounted on one end of the extension seat, and the micro threaded rod is fixedly connected to the output shaft of the micro motor.

[0009] Preferably, in order to limit the movement of the threaded block by means of the limiting slide rod, one end of the threaded block is slidably sleeved on the limiting slide rod fixed on the inner wall of the extension seat.

[0010] Preferably, in order to clean the connecting pin using the cleaning sleeve, the rotary cleaning assembly includes the cleaning sleeve rotatably mounted on the U-shaped positioning seat, the cleaning sleeve being horizontally aligned with the connecting through hole, and the driving gear ring being fixedly sleeved on the cleaning sleeve, the driving gear ring being connected to the transmission connection assembly.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-4 As shown, this embodiment provides a hydraulic system stabilizing chassis for a tipper, including a fixed chassis 1, a rotating chassis 2, and a pin-type rotating connection assembly 3, which is fixedly connected to the tipper as a connecting member; the rotating chassis 2 is rotatably connected to the fixed chassis 1 via a rotating seat; the pin-type rotating connection assembly 3 is divided into two groups, which are respectively fixed on the fixed chassis 1 and the rotating chassis 2. The pin-type rotating connection assembly 3 includes a U-shaped positioning seat 301 installed on the fixed chassis 1 and the rotating chassis 2, and a connecting pin 4 is inserted into the corresponding connecting through holes opened on the U-shaped positioning seat 301 and the hydraulic cylinder 6. An extension seat 302 is fixedly installed on the side wall of the U-shaped positioning seat 301, and a miniature threaded rod 30 is rotatably inserted into the extension seat 302. 3. A movable threaded block 304 is threaded onto the miniature threaded rod 303. The connecting pin 4 is fixedly connected to the movable threaded block 304 via a bending plate 305. One end of the miniature threaded rod 303 is connected to the transmission connection assembly 7. A miniature motor 306 is fixedly installed at one end of the extension seat 302. One end of the miniature threaded rod 303 is fixedly connected to the output shaft of the miniature motor 306. One end of the movable threaded block 304 is slidably sleeved on the limiting slide rod 307 fixed on the inner wall of the extension seat 302. In use, the miniature motor 306 at the end of the extension seat 302 is started, which drives the miniature threaded rod 303 to rotate, causing the movable threaded block 304 to move along the limiting slide rod 307. The bending plate 305 drives the connecting pin 4 to move in the connecting through hole of the U-shaped positioning seat and the hydraulic cylinder 6, realizing the installation or removal of the hydraulic cylinder 6, which improves the convenience of disassembly and maintenance.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 4As shown, a connecting pin 4 and a rotating cleaning assembly 5 horizontally corresponding to the connecting pin 4 are mounted on the pin-type rotating connection assembly 3. A hydraulic cylinder 6 is rotatably mounted on the connecting pin 4. The rotating cleaning assembly 5 is connected to the pin-type rotating connection assembly 3 via a transmission connection assembly 7. The rotating cleaning assembly 5 includes a cleaning sleeve 501 rotatably mounted on a U-shaped positioning seat 301. The cleaning sleeve 501 is horizontally corresponding to the connecting through hole. A drive gear ring 502 is fixedly sleeved on the cleaning sleeve 501, and the drive gear ring 502 is connected to the transmission connection assembly 7. The transmission connection assembly 7 includes a connecting column 701 rotatably mounted on a U-shaped positioning seat 301. A drive gear 702 is fixedly sleeved on the connecting column 701, and the drive gear 702 meshes with a drive gear ring 502. One end of the connecting column 701 is connected to one end of a miniature threaded rod 303 via a timing belt 703. In use, the miniature threaded rod 303 rotates, which drives the connecting column 701 to rotate via the timing belt 703. The drive gear 702 on the connecting column 701 rotates accordingly. Because the drive gear 702 meshes with the drive gear ring 502 on the cleaning sleeve 501, it drives the cleaning sleeve 501 to rotate. The cleaning sleeve 501 is horizontally aligned with the connecting through hole of the connecting pin 4. During its rotation, it can clean the connecting pin 4 that passes through or is located in the connecting through hole, ensuring the cleanliness of the connection part and ensuring the stable operation of the hydraulic system and the normal operation of the chassis.
