Description

Technical Field

[0001] The utility model relates to the field of pressure vessels, in particular to an impact resistance detection device for pressure vessels which is easy to fix. Background Art

[0002] Pressure vessels refer to closed equipment that holds gas or liquid and bears a certain pressure. Pressure vessels are divided into reaction vessels, heat transfer vessels, separation vessels and storage and transportation vessels according to their uses. The design pressure of pressure vessels is divided into four pressure levels: low pressure, medium pressure, high pressure and ultra-high pressure. Pressure vessels are mainly used to complete the physical and chemical reactions of working media, which are called reaction vessels. Leakage and explosion may occur during use. The power generated by leakage and explosion is very strong and will cause serious consequences. Therefore, pressure vessels are specified as special equipment, and there are strict requirements for their production and use.

[0003] After searching, a utility model patent with the publication number CN210108845U specifically discloses a fixing device for testing the pressure resistance of pressure vessels, which relates to the technical field of pressure vessels. The fixing device for testing the pressure resistance of pressure vessels comprises a fixing plate, the upper surface of which is fixedly connected with symmetrical fixing legs, the upper surface of which is provided with a placement groove, the interior of which is provided with a pressure vessel, and the sides of the two fixing legs close to each other are fixedly connected with symmetrical strong springs. The fixing device for testing the pressure resistance of pressure vessels can make the two sliding plates close to each other through the elastic force provided by the strong springs, and the pressure vessel can be fixed by the sliding plates close to each other in cooperation with the sponge plates, and the sliding plates can drive the two sliders close to each other in cooperation with the insertion rod, so that the two clamping plates can be brought close to each other, thereby better fixing the pressure vessel and avoiding the pressure vessel from not having a fixed effect.

[0004] In the above patent, the pressure vessel is fixed by bringing the sliding plates closer to each other, so that the two sets of sliders are close to each other and cooperate with the insert rod to bring the clamping plates closer to each other. However, during use, since the container needs to be fixed by clamping it closer to each other, the exposed part of the container is reduced, and the position after fixation is limited. The stamping detection device can only perform stamping tests from a single angle because of the container clamping and fixation. Since the stamping test needs to be performed from different angles of the container, when the angle needs to be changed, the container needs to be released and then fixed again, which greatly reduces the efficiency of the detection.

[0005] Therefore, it is necessary to invent a pressure vessel impact resistance detection device that is easy to fix to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a pressure vessel impact resistance testing device which is easy to fix. By controlling the fixed half ring through bolts, the pressure vessel can quickly adjust the angle of the stamping test, so as to solve the problem in the prior art that changing the angle during the stamping test of the pressure vessel requires a lot of cumbersome operations, thereby reducing the efficiency of the test.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure vessel impact resistance detection device that is easy to fix, comprising: a base, electric slide rails are symmetrically connected to the top of the base, and three groups of electric slide rails are arranged in sequence, two of each group, and fixed frames are symmetrically slidably connected to the top of the symmetrical electric slide rails, and the electric slide rails are used to drive the two groups of fixed frames to slide toward each other;

[0008] A fixing assembly, installed in two sets of fixing frames, for fixing the pressure vessel;

[0009] The stamping assembly is installed in two sets of fixed frames and is used to perform stamping inspection on pressure vessels.

[0010] Preferably, the fixing assembly includes: a threaded hole, which is symmetrically opened on the inner wall of the fixing frame, a bolt is threaded in the threaded hole, a fixing half ring is rotatably connected to one side of the bolt, a rubber pad is fixedly connected to the inner side of the fixing half ring, the fixing half ring is arranged in the fixing frame, and the nut part of the bolt is arranged on the outside of the fixing frame.

[0011] Preferably, guide holes are symmetrically provided on the inner wall of the fixed frame, and the guide holes are symmetrically provided in groups of two on the inner wall of the fixed frame, and the guide holes are respectively arranged in groups of two on both sides of the threaded hole, and a guide rod is symmetrically installed on one side of the fixed half ring, and the guide rod is connected with the corresponding guide hole.

[0012] Preferably, the stamping assembly comprises: a limiting groove, which is symmetrically arranged on the upper and lower inner walls of the fixed frame, a limiting block is slidably connected in the limiting groove, a connecting frame is arranged in the fixed frame, and the connecting frame is fixedly connected to the limiting block.

[0013] Preferably, a servo motor is installed on the outside of the fixed frame, and a screw is fixedly connected to the output end of the servo motor. The screw is rotatably connected to the outside of the fixed frame, an internal thread block is threaded on the screw, and a connecting rod is fixedly connected to one side of the internal thread block. A through groove is opened on the surface of the fixed frame, and the through groove is slidably connected to the connecting rod.

[0014] Preferably, the connecting rod is fixedly connected to the outer side of the connecting frame, three groups of cylinders are installed on the inner wall of the connecting frame, and the output end of the cylinder is fixedly connected to an extrusion ring.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] By moving the two sets of fixing frames, the fixing half ring slightly fixes the pressure vessel. At this time, by turning the bolt, the fixing half ring completely fixes the pressure vessel. At this time, the cylinder drives the extrusion ring to perform stamping inspection on the surface of the pressure vessel, and the extrusion ring can change the inspection position through the cooperation of the screw and the internal thread block. When the inspection angle needs to be changed, it is only necessary to slightly loosen the fixing half ring by turning the bolt so that the pressure vessel is still between the two sets of fixing half rings. At this time, the fixing half ring can be re-fixed after the angle of the pressure vessel is rotated. Through this operation, the operating process of the pressure vessel stamping inspection can be effectively simplified, and the efficiency of the pressure vessel stamping inspection can be greatly improved.

[0030] like Figure 4 and Figure 5 As shown, guide holes 203 are symmetrically provided on the inner wall of the fixed frame 102, and the guide holes 203 are symmetrically provided in groups of two on the inner wall of the fixed frame 102, and the guide holes 203 are respectively provided in groups of two on both sides of the threaded hole 201, and a guide rod 204 is symmetrically installed on one side of the fixed half ring 205, and the guide rod 204 is connected through the corresponding guide hole 203, and the fixed half ring 205 can be limited when moving through the cooperation of the guide rod 204 and the guide hole 203.

[0031] like Figure 2 and Figure 3 As shown, the stamping component 003 includes: a limit groove 301, which is symmetrically arranged on the upper and lower inner walls of the fixed frame 102, a limit block 302 is slidably connected in the limit groove 301, and a connecting frame 303 is arranged in the fixed frame 102, and the connecting frame 303 is fixedly connected to the limit block 302, and the fixed frame 102 is limited by the limit block 302.
