Description

Technical Field

[0001] This utility model relates to the field of pipe testing technology, specifically a hydrostatic testing machine. Background Technology

[0002] The hydrostatic testing machine is mainly used to test the pressure resistance and burst strength of materials (such as pipes, hoses, containers, thermoplastic pipes, composite pipes, etc.) under long-term constant internal pressure and constant temperature. This equipment can simulate pressure and temperature changes under actual working conditions to perform hydrostatic tests on materials to evaluate their performance and safety during use.

[0003] In existing hydrostatic testing machines, during testing, the access to and retrieval of test materials typically requires manual opening and closing of the media tank door. The high temperature and pressure environment inside the equipment during testing poses a risk of injury to personnel, thus reducing the safety of the equipment. Furthermore, the testing requires securing the test tubing to improve accuracy, but the clamps used for this purpose are usually non-adjustable. When testing different tubing specifications, it's necessary to change to clamps of the corresponding specifications, increasing procurement costs and reducing testing efficiency due to the frequent clamp changes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes the extension of the piston rod of the second cylinder to drive the transmission rod forward, thereby pushing the first rotating rod to rotate counterclockwise. As the rotation angle of the first rotating rod changes, one side of the chamber door rises, while the other side of the chamber door rotates along the rotating shaft via the connecting seat, allowing the chamber door to open, thus improving the safety of the device. The first cylinder is activated, and its piston rod drives the adjusting block upward.

The chiller 5 is a high-power industrial chiller used to improve the cooling effect of the equipment. A door 3 is mounted on the top of the medium tank 2. A fixing frame 6 is fixedly connected to the bottom inner side of the medium tank 2, and a fixing rod 7 is fixedly connected to the inner wall of the medium tank 2. A heating pipe 8 and a circulation pump 9 are installed inside the medium tank 2. The heating pipe 8 heats the medium according to the user-set temperature to achieve the required test temperature. The circulation pump 9 circulates the medium within the medium tank 2 through a circulation pipeline to ensure uniform temperature distribution. The machine also includes a drive assembly 10 mounted at the bottom of the fixing frame 6. The inner side of the fixing frame 6... The device is equipped with two connecting shafts 11, which facilitate the rotation of the connecting rod 12 around its center. Connecting rods 12 are rotatably connected to the outer sides of both connecting shafts 11. When the adjusting block 102 moves up and down, the lever 131 slides along the guide groove 132, thereby causing the connecting rod 12 to rotate around the connecting shaft 11. The other end of the lever 12 then drives the clamping block 14 to adjust its spacing. A lever assembly 13 is provided inside the drive assembly 10, and one end of the connecting rod 12 is provided with a fixing device. The clamping block 14 for the test material is provided with a guide component 15 on its outer side to improve its movement stability; a connecting component 16 is provided at the bottom of the box door 3; a transmission component 17 is provided on the outer side of the fixing rod 7; two sets of folding components 18 are symmetrically provided on the outer side of the transmission component 17; a sealing component 19 is provided at the bottom of the box door 3; a silicone rubber strip sealing gasket is provided at the bottom of the box door 3 by providing the sealing component 19; a corresponding sealing groove is provided at the top of the medium tank 2, so that there is no air leakage inside the medium tank 2 when the temperature is high, thereby improving the sealing performance of the equipment.

[0024] The drive assembly 10 includes a first cylinder 101 disposed at the bottom of the fixed frame 6. When the piston rod of the first cylinder 101 moves, it drives the adjusting block 102 to move up and down. The piston rod of the first cylinder 101 is provided with the adjusting block 102. When the adjusting block 102 moves, the change in height causes the toggle block 131 to slide along the inner side of the guide groove 132, thereby changing the position of one end of the connecting rod 12. The actuation assembly 13 includes a toggle block 131 fixed to one end of the connecting rod 12. The toggle block 131 facilitates the movement of the toggle block along the guide groove 132. The guide groove 132 slides inside, causing the connecting rod 12 to rotate at a certain angle; the guide groove 132 is provided on the inner side of the adjusting block 102, and the outer side of the lever 131 is slidably connected to the inner side of the guide groove 132; the guide assembly 15 includes a slider 151 fixed to the outer side of the clamping block 14, and a slide groove 152 is provided on the top of the fixing frame 6. By setting the guide assembly 15, when the clamping block 14 moves, it causes the slider 151 to slide along the slide groove 152. The slide groove 152 guides the movement path of the clamping block 14, thereby improving the stability of the movement of the clamping block 14.

[0025] The connecting assembly 16 includes a rotating shaft 161 disposed inside the medium tank 2. Two connecting seats 162 are rotatably connected to the outer side of the rotating shaft 161, and the outer sides of the two connecting seats 162 are fixedly connected to the bottom of the tank door 3. By setting the connecting assembly 16, when the tank door 3 is opened, one side of the tank door 3 rotates around the rotating shaft 161 via the connecting seats 162. The transmission assembly 17 includes a second cylinder 171 disposed outside the fixed rod 7. By setting the second cylinder 171, its bottom is rotatably connected to the outer side of the fixed rod 7, and its piston rod is rotatably connected to the outer side of the transmission rod 172. When its piston rod extends, it drives the transmission rod 172 to move forward, thereby pushing the first rotating rod 181 to rotate counterclockwise. The piston rod of cylinder 171 is provided with a transmission rod 172. When the transmission rod 172 moves, it will drive the first rotating rod 181 and the second rotating rod 182 to fold or unfold. The folding assembly 18 includes a first rotating rod 181 fixed to one end of the transmission rod 172. One end of the first rotating rod 181 is rotatably connected to the second rotating rod 182. The other end of the second rotating rod 182 is rotatably connected to the outside of the fixed rod 7, and the other end of the first rotating rod 181 is rotatably connected to the bottom of the door 3. When the first rotating rod 181 rotates counterclockwise, as the rotation angle changes, it will drive one side of the door 3 to rotate and open.

[0026] Working principle: In use, the chamber door 3 needs to be opened first. The piston rod of the second cylinder 171 extends and drives the transmission rod 172 to move forward, thereby pushing the first rotating rod 181 to rotate counterclockwise. As the rotation angle of the first rotating rod 181 changes, it will drive one side of the chamber door 3 to rise. At the same time, the other side of the chamber door 3 rotates along the rotating shaft 161 through the connecting seat 162, so that the chamber door 3 is opened. Then, the test material is put into the medium box 2. Then the first cylinder 101 is started, and its piston rod drives the adjusting block 102 to move upward. Through the change of height, the lever 131 slides into the low point of the guide groove 132, thereby changing the position of one end of the connecting rod 12, so that the connecting rod 12 rotates around the connecting shaft 11 as the center. Its other end drives the clamping block 14 to tighten inward, clamping and fixing the test material.
