Description

Technical Field

[0001] The utility model relates to the technical field of chemical detection, in particular to a chemical tank weld detection device. Background Art

[0002] With the rapid development of the national economy, large-scale factories such as petroleum, chemical, and steel enterprises are being built continuously. There are many pressure vessels in these large enterprises, especially vertical storage tanks. Vertical storage tanks are generally composed of bottom plates, vertical wall panels, and conical or elliptical top plates. The various parts are connected by welding. If the welding quality is poor, the storage tank is at risk of explosion. Most fracture and explosion accidents are caused by the welding seams on the tank body. Therefore, welding quality control is the key to ensuring the safety and reliability of petrochemical equipment.

[0003] At present, the inspection of tank welds is generally carried out using a radiographic flaw detector. The radiation source is placed in an appropriate position so that the center of the radiation beam is aligned with the center of the inspected area and perpendicular to the normal of the plane or curved surface for inspection. However, existing storage tanks are large in size, heavy in weight, and cumbersome to move. It is not easy for the radiographic flaw detector to conduct a comprehensive inspection of the welds on the storage tanks, and positioning inspection is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art and to propose a device that is convenient for positioning and comprehensively detecting the welds of chemical tanks.

[0030] Reference Figure 1-3 , a chemical tank weld detection equipment, is used for chemical tank weld detection, in order to facilitate the positioning detection of large tank welds.

[0031] The chemical tank weld detection equipment comprises a base 1, a support frame 2, two clamping rods 11 and a mounting block 6;

[0032] The bottom of the base 1 is provided with universal wheels 101, which facilitates the movement of the base 1, so that the equipment can be moved around the tank body 8 to perform a comprehensive inspection of the welds of the tank body 8;

[0033] The support frame 2 is fixedly connected to the base 1, and a first fixed wheel 9 is provided on one side of the support frame 2. One end of the two clamping rods 11 is rotatably connected to the support frame 2, and a second fixed wheel 10 is provided on the other end. A threaded rod 3 is rotatably connected to one side of the support frame 2. The external thread of the threaded rod 3 is connected to a threaded sleeve 4. A connecting rod 5 is rotatably connected between the threaded sleeve 4 and the two clamping rods 11. A hand wheel 301 is provided at one end of the threaded rod 3. The hand wheel 301 is used to facilitate the rotation of the threaded rod 3, so that the threaded sleeve 4 moves outside the threaded rod 3. The threaded rod 3 and the two clamping rods 11 are connected to each other. The axes of the connecting rod 5 and the two clamping rods 11 are all located on the same horizontal plane. The two connecting rods 5 drive the two clamping rods 11 to rotate respectively, so that the clamping rods 11 are opened or closed to clamp the tank body 8 between the first fixed wheel 9 and the two second fixed wheels 10. The two clamping rods 11 are arc-shaped, and the first fixed wheel 9 and the two second fixed wheels 10 are all located on the same horizontal plane, so that it is convenient for the clamping rods 11 to clamp the tank body 8. The outside of the first fixed wheel 9 and the two second fixed wheels 10 are provided with rubber sleeves to prevent the fixed wheels from causing damage to the outside of the tank body 8.

[0034] A slide groove 201 is provided on the support frame 2, and a screw 12 is provided inside the slide groove 201. The mounting block 6 is arranged on the screw 12, and the mounting block 6 is slidably connected in the slide groove 201, and a detector probe 7 is provided on one side of the mounting block 6. An X-ray machine is provided on the base 1, and the X-ray machine is connected to the detector probe 7. A servo drive motor is provided inside the slide groove 201, and the output shaft of the servo drive motor is connected to the screw 12. The servo drive motor can drive the screw 12 to rotate, thereby driving the mounting block 6 to move up and down inside the slide groove 201, thereby adjusting the position of the detector probe 7 so that it is aligned with the weld of the tank body 8, which is convenient for accurate detection of the weld of the tank body 8.

[0035] The working principle of the chemical tank weld detection equipment is as follows: when in use, the equipment is first moved to one side of the tank body 8 to be detected, so that the first fixed wheel 9 is against the outer wall of the tank body 8, and then the threaded rod 3 is rotated by the handwheel 301 to make the threaded sleeve 4 move on the outside of the threaded rod 3, thereby driving the two clamping rods 11 to rotate through the two connecting rods 5, so that the clamping rods 11 are opened or closed to clamp the tank body 8 between the first fixed wheel 9 and the two second fixed wheels 10, and then the servo drive motor drives the lead screw 12 to rotate, driving the mounting block 6 to move up and down inside the slide groove 201, thereby adjusting the position of the detector probe 7 to align it with the weld of the tank body 8, and finally the equipment can be pushed to move through the universal wheel 101. Since the first fixed wheel 9 and the two second fixed wheels 10 clamp the tank body 8, the equipment is moved around the tank body 8, so that the detector probe 7 moves along the weld of the tank body 8, and the weld is comprehensively and accurately detected.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
