Description

Technical Field

[0001] This utility model relates to the field of anchor body testing technology, and in particular to a high temperature and high pressure testing device. Background Technology

[0002] In deep geotechnical engineering projects such as deep mining and deep-buried tunnels, the underground environment is characterized by high temperature and high pressure. With increasing depth, the geothermal gradient causes a rise in temperature, and the weight of the overlying rock and soil generates high pressure. Taking deep gold mining as an example, when the mining depth exceeds 1,000 meters, the geothermal temperature can reach over 50°C, and the pressure generated by the geostress can reach tens of megapascals. High-temperature and high-pressure testing of anchor bodies can assess their ability to adapt to special geological conditions and ensure project safety. During the testing process, high-temperature and high-pressure test chambers are commonly used to test the anchor bodies. High-precision sensors such as thermocouples and strain gauges are accurately installed at key locations on the anchor body to monitor key parameters such as temperature, stress, and strain in real time. During the heating and pressurization process, the sensor data is closely observed to ensure that the temperature and pressure rise steadily to the set values. After reaching the set high-temperature and high-pressure state, the environment is maintained for a period of time to allow the anchor body to be fully loaded, simulating long-term working conditions. Changes in parameters such as stress, strain, and displacement of the anchor body are continuously monitored, data are recorded, and any cracks or deformations are observed.

[0003] After testing anchors using common high-temperature and high-pressure test chambers, the anchors are usually in a high-temperature state. At this time, it is necessary to use auxiliary tools to remove the anchors. Moreover, even if they are successfully removed, the anchors can only rely on their own slow heat dissipation and cannot achieve rapid cooling. In practical applications, it is of great significance to quickly remove the tested anchors and cool them down in time for improving testing efficiency, ensuring the continuity of subsequent testing processes, and ensuring the timeliness of test data. Based on this situation, in order to effectively solve the above problems, this application proposes a novel high-temperature and high-pressure testing device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high temperature and high pressure testing device to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-temperature and high-pressure testing device includes a main body, with a test chamber opened in the upper half of the front of the main body. Two positioning rods symmetrically distributed on the left and right are fixedly installed at the inner end of the test chamber. A storage frame is movably sleeved on the two positioning rods. Two sets of telescopic suspension components are provided on the storage frame. A storage box is hung between the two sets of telescopic suspension components. The storage box is vertically connected, and a storage net is provided at the opening at the bottom of the storage box. A door that can be closed at the opening of the test chamber is hinged to the front of the main body. A spray box is fixedly installed in the lower half of the front of the main body. A liftable storage plate is provided inside the spray box. A spray assembly is provided on the front of the spray box.

[0006] Furthermore, the storage frame includes two sleeves and two connecting rods. The two sleeves are movably fitted onto the two positioning rods, and the two connecting rods are fixedly connected between the two ends of the two sleeves. Two sets of telescopic suspension components are movably inserted into the two connecting rods.

[0007] Furthermore, the telescopic suspension assembly includes two adjusting bolts, a hanging rod, and two springs. Both ends of the sidewalls of the two connecting rods are provided with through holes. The two adjusting bolts are respectively inserted into the two through holes on the corresponding connecting rods. The hanging rod is fixedly connected between the ends of the two adjusting bolts that are close to the storage box. The two springs are respectively sleeved on the two adjusting bolts, and the two ends of the springs are respectively fixedly connected to the ends of the adjusting bolts away from the hanging rods and the outer walls of the connecting rods.

[0008] Furthermore, inverted U-shaped hanging brackets are fixedly installed at both ends of the front and rear sides of the storage box, and the U-shaped hanging brackets on both sides of the storage box are respectively hung on the hanging rods of the two sets of telescopic suspension components.

[0009] Furthermore, a first hydraulic rod is fixedly installed on the right side of the inner wall of the test chamber. A Z-shaped connecting plate is fixedly connected to the telescopic end of the first hydraulic rod, and the end of the connecting plate away from the first hydraulic rod is fixedly connected to the side wall of the inner end of the right sleeve. The top of both positioning rods is provided with a sliding groove, and the top of the inner wall of both sleeves away from the door is provided with a ball groove. Rotatable balls are provided in both ball grooves. The two balls are located in the sliding grooves on the two positioning rods and can roll inside them.

[0010] Furthermore, two support pipes are fixedly installed at the bottom of the spray box, and a second hydraulic rod is fixedly installed inside each of the two support pipes. The telescopic ends of the two second hydraulic rods are respectively fixedly connected to the two ends of the bottom of the shelf. A sealing ring fitted on the telescopic end of the second hydraulic rod is fixedly installed at the opening at the top of each of the two support pipes.

[0011] Furthermore, the water pump is fixedly installed at the bottom of the front of the spray box, with the water inlet end of the water pump connected to the bottom of the inner cavity of the spray box. The bottom end of the water pump pipe is fixedly connected to the water outlet end at the top of the water pump. The water storage pipe is fixedly installed at the top of the front of the spray box, with the top end of the water pump pipe connected to the water storage pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. After the anchor is inspected, open the box door and control the first hydraulic rod to extend. The first hydraulic rod can move the storage frame out of the test chamber through the connecting plate. At this time, the storage box is just above the storage plate in the spray box. Then control the second hydraulic rod to extend and move the storage plate up. When the storage plate contacts the storage box and pushes it up, the U-shaped hangers on both sides of the storage box will disengage from the hanging rod. At the moment of disengagement, the spring will release its elastic force to push the adjusting bolt to move the hanging rod away from the storage box. Then the storage plate will descend to a height that can remove the storage box from between the two telescopic suspension components.

[0015] 2. After removing the storage box from the shelf, lower the height to bring the storage box into the spray box. Then, run the water pump to draw water from the bottom of the spray box into the storage pipe through the water pumping pipe. Then, spray the water out through several nozzles. The water sprayed from the nozzles will spray onto the anchors inside the storage box, thereby cooling down the anchors that have just been inspected inside the storage box.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a high-temperature and high-pressure testing device, including a main body 1. A test chamber is formed in the upper half of the front of the main body 1. Two positioning rods 4, symmetrically distributed, are fixedly installed at the inner end of the test chamber. A storage frame 5 is movably sleeved on the two positioning rods 4. Two sets of telescopic suspension components 6 are provided on the storage frame 5. A storage box 7 is hung between the two sets of telescopic suspension components 6. The storage box 7 is vertically continuous, and a storage net is provided at the opening at the bottom of the storage box 7. A door 2, which can be closed at the opening of the test chamber, is hinged to the front of the main body 1. The lower part of the front of the main body 1... The half-section is fixedly installed with a spray box 10. Inside the spray box 10, there is a liftable shelf 11. The front of the spray box 10 is equipped with a spray assembly. After the anchor is tested, the first hydraulic rod 8 is extended through the connecting plate 9 to move the shelf frame 5 out of the test chamber. Then, the shelf 11 is moved up to push the shelf box 7, which can be removed from between the two telescopic suspension components 6 on the shelf frame 5. Then, the shelf 11 is moved down to bring the shelf box 7 into the spray box 10. Then, the spray assembly can cool down the anchor that has just been tested inside the shelf box 7.

[0025] like Figure 2 and Figure 3 As shown, the storage frame 5 includes two sleeves 51 and two connecting rods 52. The two sleeves 51 are movably sleeved on the two positioning rods 4 respectively, and the two connecting rods 52 are fixedly connected between the two ends of the two sleeves 51 respectively. Two sets of telescopic suspension components 6 are movably inserted into the two connecting rods 52 respectively. The storage box 7 can be erected through the storage frame 5 and the two sets of telescopic suspension components 6.

[0026] like Figure 2 and Figure 3As shown, the telescopic suspension assembly 6 includes two adjusting bolts 61, a hanging rod 62, and two springs 63. Both ends of the sidewalls of the two connecting rods 52 have through holes 21. The two adjusting bolts 61 are respectively inserted into the two through holes 21 on the corresponding connecting rods 52. The hanging rod 62 is fixedly connected between the ends of the two adjusting bolts 61 closest to the storage box 7. The two springs 63 are respectively sleeved on the two adjusting bolts 61, and both ends of the springs 63 are fixedly connected to the ends of the adjusting bolts 61 away from the hanging rods 62 and to the outer wall of the connecting rods 52. When setting up the storage box 7, first, the two U-shaped hanging pieces 71 on one side of the storage box 7 are engaged with the hanging rod 62 in one set of telescopic suspension assemblies 6. Then, the storage box 7 is pulled to engage the two U-shaped hanging pieces 71 on the other side with the hanging rod 62 in the other set of telescopic suspension assemblies 6. After setting up the storage box 7, the springs 63 in both sets of telescopic suspension assemblies 6 are in a compressed state.

[0027] like Figure 2 and Figure 3 As shown, inverted U-shaped hangers 71 are fixedly installed at both ends of the front and rear sides of the storage box 7, and the U-shaped hangers 71 on both sides of the storage box 7 are respectively hung on the hanging rods 62 in the two sets of telescopic suspension assemblies 6. When the storage plate 11 pushes the storage box 7 to move upward, the U-shaped hangers 71 can be disengaged from the hanging rods 62, so that the storage box 7 can be removed from between the two sets of telescopic suspension assemblies 6.

[0028] like Figure 2 and Figure 4 As shown, a first hydraulic rod 8 is fixedly installed on the right side of the inner wall of the test chamber. A Z-shaped connecting plate 9 is fixedly connected to the telescopic end of the first hydraulic rod 8.

When the first hydraulic rod 8 is extended, the connecting plate 9 can drive the storage frame 5 to move out of the test chamber along the direction of the two positioning rods 4. Through the cooperation of the balls 20 and the sliding grooves 19, the movement range of the storage frame 5 can be limited to prevent the storage frame 5 from detaching from the positioning rods 4.

[0029] like Figure 2 and Figure 5As shown, two support pipes 16 are fixedly installed at the bottom of the spray box 10. A second hydraulic rod 17 is fixedly installed inside each of the two support pipes 16. The telescopic ends of the two second hydraulic rods 17 are respectively fixedly connected to the two ends of the bottom of the shelf 11. A sealing ring 18 is fixedly installed at the opening at the top of each of the two support pipes 16 and sleeved on the telescopic end of the second hydraulic rod 17. By controlling the second hydraulic rod 17, the shelf 11 can be pushed upward, so that the shelf 11 can remove the shelf box 7 and bring it into the spray box 10.

[0030] like Figure 2 and Figure 5 As shown, the spray assembly includes a water suction pipe 12, a water storage pipe 13, a water pump 15, and several nozzles 14. The water pump 15 is fixedly installed at the bottom of the front of the spray box 10, and the water inlet of the water pump 15 is connected to the bottom of the inner cavity of the spray box 10. The bottom end of the water suction pipe 12 is fixedly connected to the water outlet at the top of the water pump 15. The water storage pipe 13 is fixedly installed at the top of the front of the spray box 10, and the top end of the water suction pipe 12 is connected to the water storage pipe 13. Several nozzles 14 are evenly fixedly installed on the side of the water storage pipe 13, and each nozzle 14 penetrates the side of the spray box 10 and extends into its interior. Each nozzle 14 is configured as follows: Tilting downwards at 20°, the placement plate 11 brings the placement box 7 to the spray box 10. The water pump 15 is then operated to pump water from the bottom of the spray box 10 into the storage pipe 13 through the water extraction pipe 12. The water is then sprayed out through several nozzles 14. The water sprayed from the nozzles 14 will spray onto the anchors inside the placement box 7, thereby cooling the anchors that have just been tested inside the placement box 7. After removing the placement box 7, it can be re-erected between the two telescopic suspension components 6. Then, the first hydraulic rod 8 is controlled to retract, bringing the placement box 7 into the test chamber, where other anchors to be tested can be subjected to high temperature and high pressure tests.

[0031] like Figure 1 As shown, a control unit 3 is fixedly installed on the right side of the main body 1. A display screen and control buttons are provided on the front of the control unit 3. The temperature and pressure inside the test chamber can be monitored in real time through the display screen on the control unit 3, and the device can be operated through the control buttons.
