Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of pressure vessels, in particular to a pressure vessel inspection and detection device. Background Art

[0002] In fire-fighting equipment, gas cylinders are containers for storing fire-extinguishing gas. The gas pressure inside the gas cylinders generally reaches more than a dozen atmospheres. If gas cylinders that have not been tested for air tightness are directly used in production practice, there will be a potential danger of gas cylinder rupture and injury. Therefore, for the quality and safety of the fire-fighting equipment itself, all fire-fighting gas cylinders need to undergo air tightness testing before they are filled and shipped out of the factory;

[0003] In the prior art, the Chinese utility model with announcement number: CN213779410U discloses a fire-fighting gas cylinder air tightness detection device, including a support plate, a fixed plate is fixedly installed on the upper surface of the support plate, a slide groove is provided on the inner lower surface of the fixed plate, a slide plate is slidably connected inside the slide groove, the lower surface of the slide plate is fixedly installed on the middle position of the upper surface of the pad plate, an electric push rod is fixedly installed on the lower surface of the pad plate, the end of the electric push rod is fixedly installed on the upper surface of the lifting plate, a first placement seat and a second placement seat are provided on the lower surface of the lifting plate, a first card groove is provided on the inner lower surface of the first placement seat, and a second card groove is provided on the inner lower surface of the second placement seat; the electric push rod is controlled to stretch, thereby pushing the lifting plate to move downward, and at the same time driving the fire-fighting gas cylinder to move downward until the fire-fighting gas cylinder enters the water tank, so as to detect the air tightness of the fire-fighting gas cylinder, after the detection is completed, the electric push rod is controlled to shrink, thereby pulling the lifting plate to move upward, and then the fire-fighting gas cylinder can be removed;

[0004] Although the above technical scheme can realize the air tightness detection of the pressure vessel, the above technical scheme increases the labor intensity of the staff in the process of lifting and fixing the pressure vessel by lifting the pressure vessel. The high labor intensity when loading and unloading the pressure vessel leads to inconvenience in disassembly and assembly. The disassembly and assembly efficiency of the pressure vessel needs to be further improved. Therefore, we need to propose a pressure vessel inspection and testing device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a pressure vessel inspection and detection device, comprising:

[0025] A water tank 1, with driving mechanisms 3 disposed on both sides of the water tank 1, a mounting mechanism 4 mounted on one end of each of the two sets of driving mechanisms 3, and two sets of limiting mechanisms 5 symmetrically disposed on the mounting mechanism 4;

[0026] The driving mechanism 3 comprises a fixed frame 31, in which a lifting cylinder 32 is installed, and a connecting right-angle plate 33 is fixedly connected to the telescopic end of the lifting cylinder 32;

[0027] The installation mechanism 4 includes an installation block 41. On both sides of the installation block 41, multiple groups of installation grooves 42 are provided, and a support mesh plate 46 is fixedly connected to the lower surface of the installation block 41;

[0028] The limiting mechanism 5 includes a limiting frame 51. On one side of the limiting frame 51, multiple groups of limiting grooves 53 are provided. On one side of each group of limiting grooves 53, multiple telescopic rods 54 are fixedly connected, and springs 55 are sleeved outside the multiple telescopic rods 54. One ends of the multiple groups of telescopic rods 54 are fixedly connected with anti-slip clamping plates 56.

[0029] One side of the limiting frame 51 adjacent to the multiple groups of limiting grooves 53 is hinged to the installation block 41. On the other side of the limiting frame 51 adjacent to the multiple groups of limiting grooves 53, two groups of connecting buckles 52 are provided. The limiting frame 51 can be opened and closed conveniently through the connecting buckles 52, and can quickly fix the pressure vessel between the limiting frame 51 and the installation block 41, thereby improving the efficiency of loading and unloading the pressure vessel.

[0030] Anti-slip inner plates 45 are bonded to the inner sides of the multiple groups of installation grooves 42. The multiple groups of installation grooves 42 are arranged at equal intervals, and the horizontal cross-section of the installation groove 42 is semicircular. The pressure vessel is clamped by the anti-slip inner plate 45 and the anti-slip clamping plate 56, thereby increasing the friction coefficient with the pressure vessel immersed in water, and thus ensuring the stability of the pressure vessel during airtightness detection in water.

[0031] Multiple groups of water guiding through holes 43 are provided on the upper surface of the installation block 41. Four groups of water guiding side holes 44 communicating with the installation grooves 42 are provided inside the water guiding through holes 43, and each group of water guiding side holes 44 has multiple ones. Through the water guiding through holes 43, the water can quickly submerge the pressure vessel, and then through the water guiding side holes 44, the pressure vessels in each installation groove 42 can be quickly submerged in water.

[0032] Two groups of jack holes 35 are provided on the upper surface of the fixed frame 31. Plug plates 34 are welded on both sides of the connecting right-angle plate 33, and the plug plates 34 are slidably inserted into the jack holes 35. The stability of the pressure vessel during lifting is improved through the connecting right-angle plate 33 and the plug plates 34.

[0033] A control panel 2 is installed on one side of the water tank 1 adjacent to the two groups of fixed frames 31. The control panel 2 is electrically connected to the two groups of顶升 cylinders 32 respectively. Multiple groups of legs are provided on the lower surface of the water tank 1. Through the control panel 2, it is convenient to control the start and stop of the顶升 cylinders 32, and thus it is convenient to control the lifting of the pressure vessel after airtightness detection by immersion in water, and the operation is simple.

[0034] The vertical cross-section of the fixed frame 31 is in an inverted U shape. Multiple groups of connecting bolts are inserted on one side of the connecting right-angle plate 33, and the multiple groups of connecting bolts are bolted to the installation block 41. The opening on one side of the fixed frame 31 is convenient for repairing the顶升 cylinder 32, and at the same time, it is convenient to disassemble, repair and clean the installation mechanism 4 through the connecting bolts.

[0035] When in use, the mounting mechanism 4 is above the water tank 1, the connecting buckle 52 of the limiting mechanism 5 is opened to place the pressure vessel in the mounting groove 42, and then the limiting frame 51 is closed. When closed, the anti-skid splint 56 contacts the pressure vessel and compresses the spring 55, thereby increasing the clamping force on the pressure vessel, and the anti-skid splint 56 and the anti-skid inner plate 45 increase the friction coefficient with the pressure vessel, and the control panel 2 controls the retracting end of the lifting cylinder 32 to insert the plug plate 34 into the plug hole 35, so that the mounting mechanism 4 and the limiting mechanism 5 are immersed in the water of the water tank 1, and the water is immersed in the pressure vessel placement cavity formed by the mounting groove 42 and the limiting groove 53 through the supporting mesh plate 46, and at the same time, the water flows into each pressure vessel placement cavity from the water guide hole 43 of the mounting block 41 from the water guide side hole 44, thereby accelerating the efficiency of water immersion of the pressure vessel, thereby facilitating the staff to observe the air tightness of the pressure vessel, and simultaneously detect the air tightness of multiple pressure vessels, thereby improving the efficiency of the air tightness detection of the pressure vessel.
