Description

Technical Field

[0001] This utility model relates to the field of special equipment, and in particular to a workbench for testing special equipment. Background Technology

[0002] Special equipment refers to eight categories of equipment that involve life safety and are highly dangerous, including boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and special motor vehicles for on-site use. To ensure the safe operation of special equipment, the state has strict regulations on all types of special equipment in terms of production, use, and inspection and testing, and implements full-process supervision.

[0003] Special equipment refers to equipment that may cause accidents during use due to factors such as structure, mechanical strength, electrical issues, safety devices, or management, endangering personal and property safety. To ensure the safe operation of such equipment, it is necessary to conduct regular inspections using specialized testing equipment, such as testing the material strength, wall thickness, and weld quality of pressure-bearing equipment like boilers and pressure vessels.

[0004] When testing special equipment such as pressure cookers, it is necessary to test the material strength of the pressure cooker, as well as its airtightness and safety when used under maximum pressure. Existing workbenches can only test a limited range of data and cannot simultaneously test material strength and sealing performance. Furthermore, the workbenches lack a safe and sealed testing space, making them inconvenient to use for testing special equipment. Therefore, it is necessary to propose a workbench for testing special equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a special equipment testing workbench to solve the problems mentioned in the background art, such as the limited data that existing workbenches can detect, the inability to successively test material strength and sealing performance, and the lack of a safe and sealed testing space during testing, which makes the special equipment testing workbench inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a workbench for testing special equipment, comprising a workbench, a sealing cover hinged to the top of the workbench, an I-shaped plate fixedly connected to the top of the workbench, an L-shaped plate movably sleeved in the middle of the I-shaped plate, a rotating rod rotatably connected to the side of the I-shaped plate, the rotating rod passing through the side of the I-shaped plate and threadedly connected to the L-shaped plate, two limiting rods fixedly connected to the top of the L-shaped plate, a T-shaped plate movably sleeved between the two limiting rods, a hardness tester fixedly connected to the side of the T-shaped plate, and an airtight assembly provided in the inner cavity of the workbench.

[0007] Preferably, the airtight assembly includes an electric telescopic rod fixedly installed at the bottom of the inner cavity of the workbench, a turntable fixedly connected to the output end of the electric telescopic rod, a limit cylinder rotatably connected to the top of the turntable, a plurality of positioning rods threadedly connected to the side of the limit cylinder, a rubber head fixedly connected to the end of each positioning rod, and a thermal imager fixedly installed on the inner wall of the workbench.

[0008] Preferably, a fixing plate is fixedly connected to the side of the limiting cylinder, and a rod is inserted through the top of the fixing plate. A ring of positioning holes is opened on the top of the turntable.

[0009] Preferably, the bottom end of the insertion rod is tapered, and the bottom end of the insertion rod is located in one of the positioning holes.

[0010] Preferably, the top of the L-shaped plate is rotatably connected to a threaded rod, which is threadedly connected to the T-shaped plate.

[0011] Preferably, a ruler is fixedly connected to the top of the L-shaped plate, and a roller is rotatably connected to the inner wall of the bottom of the L-shaped plate.

[0012] Preferably, a pneumatic pipe is fixedly inserted into the side of the workbench, and a valve is fixedly sleeved on the side of the pneumatic pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model can move the L-shaped plate along the I-shaped plate by rotating the rotating rod, so that the hardness tester comes into contact with the surface of the pressure pot to test the strength of the surface material of the pressure pot. The pressure pot can be clamped by the airtight component so that the hardness tester can quickly detect the material strength. The airtight component can also detect the airtightness of the pressure pot. Thus, the workbench can provide a safe testing environment and can continuously test different data, which greatly improves the practicality of the equipment.

[0015] 2. This utility model can drive the pressure cooker to rotate synchronously through the rotating limiting cylinder, so that the hardness tester can test the material strength of different positions of the pressure cooker. By inserting the insertion rod into the positioning hole, the pressure cooker can be prevented from deflecting, thereby ensuring the force balance between the contact surface of the hardness tester and the pressure cooker, so as to obtain accurate test data.

[0016] 3. This utility model enables the T-shaped plate to move up and down along the limiting rod via the threaded rod, so as to facilitate the hardness tester to perform strength tests on pressure cookers of different sizes at different heights. The rollers can reduce the wear caused by the friction between the L-shaped plate and the workbench surface, and the scale can accurately move the T-shaped plate to the specified height, thereby facilitating the standardized recording of test conditions and data.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] This utility model provides, for example Figures 1 to 4 The workbench for testing special equipment shown includes a workbench 1, a sealing cover 2 hinged to the top of the workbench 1, an I-shaped plate 3 fixedly connected to the top of the workbench 1, an L-shaped plate 4 movably sleeved in the middle of the I-shaped plate 3, a rotating rod 5 rotatably connected to the side of the I-shaped plate 3, the rotating rod 5 passing through the side of the I-shaped plate 3 and threadedly connected to the L-shaped plate 4, two limiting rods 6 fixedly connected to the top of the L-shaped plate 4, a T-shaped plate 7 movably sleeved between the two limiting rods 6, and a hardness tester 8 fixedly connected to the side of the T-shaped plate 7. In use, the L-shaped plate 4 can be moved along the I-shaped plate 3 by rotating the rotating rod 5, so that the hardness tester 8 comes into contact with the surface of the pressure cooker to test the strength of the surface material of the pressure cooker.

[0024] In practical use, the I-shaped plate 3 consists of two vertical plates and a straight rod, and the L-shaped plate 4 is movably sleeved on the outside of the straight rod. When the pressure cooker is clamped and fixed in place... Figure 1When the sealing cover 2 is in position, the L-shaped plate 4 moves linearly along the I-shaped plate 3 by rotating the rotating rod 5. When the L-shaped plate 4 moves towards the sealing cover 2, the hardness tester 8 will come into contact with the surface of the pressure cooker. The indenter of the hardness tester 8 applies pressure to the surface of the pressure cooker material, causing a pit of a certain depth on the surface of the pressure cooker. Then, the hardness tester 8 can calculate a hardness value based on the change in the depth of the indenter to indicate the hardness of the pressure cooker material. After this is completed, the turntable 10 is rotated in the opposite direction so that the hardness tester 8 is no longer in contact with the pressure cooker, and the test data is recorded, so that the next test can be carried out.

[0025] The inner cavity of the workbench 1 is equipped with an airtight component, which can clamp the pressure cooker so that the hardness tester 8 can quickly test the material strength. The airtightness of the pressure cooker can also be tested through the airtight component. Thus, the workbench 1 can provide a safe testing environment and continuously test different data, which greatly improves the practicality of the equipment.

[0026] The airtight assembly includes an electric telescopic rod 9 fixedly installed at the bottom of the inner cavity of the workbench 1. A turntable 10 is fixedly connected to the output end of the electric telescopic rod 9. A limiting cylinder 11 is rotatably connected to the top of the turntable 10. Multiple positioning rods 12 are threadedly connected to the side of the limiting cylinder 11. A rubber head 13 is fixedly connected to the end of each positioning rod 12. A thermal imager 14 is fixedly installed on the inner wall of the workbench 1. In use, a handle is provided on the top of the sealing cover 2 to control its opening and closing. When the sealing cover 2 is opened, the turntable 10 can be pushed upwards by the electric telescopic rod 9. After the turntable 10 moves above the workbench 1, the pressure cooker can be placed inside the limiting cylinder 11. Then, by rotating the three positioning rods 12, their rubber heads 13 come into contact with the surface of the pressure cooker to clamp it. The limiting cylinder 11 can rotate on the turntable 10 to allow for... The user rotates the positioning rod 12 to fix the pressure cooker. After fixing, the pressure cooker can be tested for material hardness by the hardness tester 8. After the hardness test is completed, the electric telescopic rod 9 drives the turntable 10 to descend into the inner cavity of the workbench 1. Then, the handle closes the sealing cover 2 to make the inner cavity of the workbench 1 a sealed space. The pressure cooker then heats the water inside and creates a high-pressure environment in its inner cavity. The temperature of the pressure cooker surface can be observed by the thermal imager 14. At this time, the sealed space in the workbench 1 provides a safe and air-free testing environment. When the pressure cooker leaks, high-temperature gas will leak from a local area of ​​the pressure cooker and be captured and recorded by the thermal imager 14. After the airtightness test is completed, the sealing cover 2 can be opened and the pressure cooker can be removed. This improves the safety of the design and increases the number of testable items, greatly increasing the practicality of the equipment.

[0027] like Figures 3 to 4As shown, a fixing plate 15 is fixedly connected to the side of the limiting cylinder 11, and a rod 16 is provided through the top of the fixing plate 15. A ring of positioning holes 17 is opened on the top of the turntable 10. When in use, the rod 16 can be inserted into the positioning hole 17 to prevent the pressure cooker from deflecting, thereby ensuring the force balance between the hardness tester 8 and the contact surface of the pressure cooker, so as to obtain accurate test data.

[0028] In practical use, the limiting cylinder 11 is rotated to adjust the hardness tester 8 to test different positions of the pressure cooker. When rotating the limiting cylinder 11, the insertion rod 16 is first pulled upward to disengage it from the positioning hole 17. Then the limiting cylinder 11 is rotated to the designated position, and the insertion rod 16 is inserted into the positioning hole 17 at the corresponding position to lock the limiting cylinder 11 and prevent the limiting cylinder 11 from deflecting when the hardness tester 8 comes into contact with the pressure cooker.

[0029] Furthermore, the bottom end of the insertion rod 16 is tapered, and the bottom end of the insertion rod 16 is located in one of the positioning holes 17. When in use, the bottom of the insertion rod 16 is tapered, and the diameter of the bottom is smaller than the diameter of its middle part, so that the insertion rod 16 can be quickly inserted into the corresponding positioning hole 17, which facilitates use and improves the detection speed.

[0030] like Figures 1 to 2 As shown, the top of the L-shaped plate 4 is rotatably connected to the threaded rod 18, which is threadedly connected to the T-shaped plate 7. The threaded rod 18 allows the T-shaped plate 7 to move up and down along the limiting rod 6, so that the hardness tester 8 can perform strength tests on pressure cookers of different sizes at different heights.

[0031] In practical use, rotating the threaded rod 18 allows the T-shaped plate 7 to move up and down along the two limiting rods 6. When pressure cookers of different heights are clamped in the limiting cylinder 11, the height of the hardness tester 8 can be adjusted to test the strength of pressure cookers of different lengths. It can also test the strength of the materials used for different heights of the pressure cooker itself.

[0032] Furthermore, a ruler 19 is fixedly connected to the top of the L-shaped plate 4, and a roller 20 is rotatably connected to the inner wall of the bottom of the L-shaped plate 4. During use, the roller 20 can reduce the wear caused by friction between the L-shaped plate 4 and the surface of the workbench 1, and improve the smoothness of the L-shaped plate 4 moving along the I-shaped plate 3. The ruler 19 can accurately move the T-shaped plate 7 to the specified height, thereby facilitating the standardized recording of test conditions and data.

[0033] Furthermore, a pressure pipe 21 is fixedly inserted into the side of the workbench 1, and a valve is fixedly sleeved on the side of the pressure pipe 21. During use, when the pressure cooker is tested for pressure sealing, if the pressure cooker itself leaks, causing the internal pressure of the workbench 1 to increase, the valve can be opened to release the pressure through the pressure pipe 21 to avoid accidents.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
