Description

Technical Field

[0001] This utility model relates to the field of jack technology, specifically a high and low temperature cycle durability test bench for jacks. Background Technology

[0002] As a commonly used lifting tool, the sealing performance and mechanical strength of jacks are prone to degradation under extreme temperatures, such as extremely cold or high temperature environments. Therefore, it is essential to conduct high and low temperature durability tests.

[0003] However, existing jack durability tests are typically conducted at room temperature, failing to simulate extreme conditions. Using a constant temperature chamber for testing is problematic because jack operation usually requires manual operation of the lever and valve, making prolonged operation within the sealed high / low temperature chamber difficult. Frequent opening of the chamber door for manual operation leads to temperature fluctuations, disrupting the experimental environment and resulting in inaccurate test results. Furthermore, repeated manual lever operation is labor-intensive, inefficient, and inconsistent in the stroke and force applied each time. Therefore, there is an urgent need for equipment that can automatically perform high / low temperature cyclic durability tests on jacks while maintaining a sealed chamber and stable temperature.

The telescopic end of the electric cylinder 308 is rotatably connected to the latch 310 through the rotating shaft 309. The latch 310 is sleeved and fixed to the end of the operating lever 202. When the electric cylinder 308 extends or retracts, it drives the latch 310 to move up and down. Due to the presence of the rotating shaft 309, the latch 310 is allowed to rotate adaptively with the angle change of the control lever 202, thereby smoothly driving the control lever 202 to complete the pumping action of the jack. The electric cylinder 308 is equipped with a control unit 311 on the right side. The control unit 311 is installed on the right side above the base 101. The outer wall of the control unit 311 is equipped with a display screen 312. Below the display screen 312 are multiple control buttons 313. The elastic sealing gasket 307 is used to maintain a tight seal with the control lever 202 when the control lever 202 moves.

[0023] The housing 102 is equipped with a jack structure 2. The jack structure 2 includes a hydraulic jack housing 201, a control lever 202, and a return valve 203. The hydraulic jack housing 201 is located on the inner side of the housing 102. The control lever 202 is installed in the middle of the outer wall of the hydraulic jack housing 201. The return valve 203 is installed on the right side of the outer wall of the hydraulic jack housing 201.

[0024] The middle position inside the housing 102 is on the same horizontal line as the middle position of the hydraulic jack housing 201.

[0025] The return valve 203 and the fixing hole 302 are respectively set.

[0026] The outer wall of the connecting return valve clamp 304 and the inner wall of the sealing ring 303 are correspondingly arranged.

[0027] The sealing ring 303 is fitted tightly against the inner wall of the fixing hole 302.

[0028] The inner wall of the fixing groove 306 and the elastic sealing gasket 307 are designed to fit tightly together.

[0029] The pivot 309 and the latch 310 are rotatably connected, and the housing 102 is integrated with the fixing hole 302 and the fixing groove 306.

The temperature control component 301 includes a heating tube and a cooling tube, and its operation is controlled by the control unit 311 to create a preset high temperature or low temperature environment inside the chamber 102.

[0032] Working principle: First, the hydraulic jack housing 201 is placed inside the housing 102, and its return valve 203 is connected to the return valve clamp 304. The operating lever 202 passes through the fixing groove 306 and rotates to be parallel to the base 101. The user uses the buckle 310 to put on the outer wall of the operating lever 202 and close the housing door 106. When in use, the operating lever 202 extends to the outside of the housing 102 through the fixing groove 306. In order to ensure that the temperature environment inside the housing 102 does not leak, the elastic sealing gaskets 307 on both sides inside the fixing groove 306 are made of elastic rubber. The two elastic sealing gaskets 307 are tightly attached to both sides of the operating lever 202. When the electric cylinder 308 drives the operating lever 202 to swing up and down in the fixing groove 306, the elastic sealing gaskets 307 deform but always maintain contact with the surface of the operating lever 202, thereby achieving dynamic sealing. The control button 313 activates the temperature control component 301 to heat or cool down, simulating extreme temperatures. The loading cylinder 103 drives the pressing plate 104 to press down the hydraulic jack housing 201. The pressure sensor 105 provides real-time pressure feedback to the display screen 312. The rotary cylinder 305 switches the return oil valve 203 via the connecting return oil valve clamp 304 to achieve jack reset. The electric cylinder 308 drives the latch 310 to repeatedly push and pull the control lever 202, completing the cycle in conjunction with the loading and reset actions. The control unit 311 coordinates the actions of each component and automatically completes the durability test according to the preset parameters.
