DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with specific embodiments.

[0024] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0025] like Figures 1 to 8As shown, the utility model provides a combustion chamber end cover weld detection device, including a frame 1, on which a water detection device 3 is arranged, the water detection device 3 includes a high-pressure water pump 31, a high-pressure resistant hose 33, a quick-release interface 34, a sealing flange 24 and a blocking portion 14, the sealing flange 24 is installed on the intake pipe 21 or the oil intake pipe 20, a one-way valve 25 is arranged on the sealing flange 24, the high-pressure water pump 31 is installed on the frame 1, the high-pressure water pump 31 is connected to the quick-release interface 34 through the high-pressure resistant hose 33, the quick-release interface 34 is detachably connected to the one-way valve 25, and the blocking portion 14 is installed on the frame 1. The blocking portion 14 can block the intake pipe 21 or the oil intake pipe 20 away from the sealing flange 24.

[0026] Through the above-mentioned design scheme, the sealing flange 24 can seal one end of the air intake pipe 21 or the oil intake pipe 20. When it is necessary to detect a certain air intake pipe 21 or the oil intake pipe 20, the blocking portion 14 is used to block the other end of the corresponding air intake pipe 21 or the oil intake pipe 20, so that the air intake pipe 21 or the oil intake pipe 20 is in a sealed state. After the quick-release interface 34 is installed on the one-way valve 25, water can flow from the one-way valve 25 into the sealed air intake pipe 21 or the oil intake pipe 20 through the quick-release interface 34, and the air intake pipe 21 or the oil intake pipe 20 is detected by air tightness.

[0027] In this embodiment, the quick-release interface 34 may be a commonly used quick-change connector, and the one-way valve 25 is compatible with the quick-change connector.

[0028] In this embodiment, a switch valve and a pressure detector are provided on the blocking portion 14, and a pressure indicator 13 is installed on the frame 1. The pressure indicator 13 is electrically connected to the pressure detector.

[0029] When water pressure detection is required, the blocking portion 14 needs to block the end of the air intake pipe 21 or the oil intake pipe 20 away from the sealing flange 24 to prevent water from flowing out from the other end of the air intake pipe 21 or the oil intake pipe 20. The pressure detector can detect the water pressure in the air intake pipe 21 or the oil intake pipe 20, and then display it through the pressure indicator 13 for easy observation. If there are holes or gaps in the weld, the water flow pressure in the air intake pipe 21 or the oil intake pipe 20 will gradually decrease. If the weld is normal, the pressure in the air intake pipe 21 or the oil intake pipe 20 will remain unchanged for a certain period of time.

[0030] In this embodiment, the switch valve can be an electromagnetic valve. After the power is turned on, the electromagnetic valve closes, so that the air intake pipe 21 or the oil intake pipe 20 is in a closed state. After the electromagnetic valve is opened, water flows out of the electromagnetic valve. The discharged water flow can also bring impurities into the air intake pipe 21 or the oil intake pipe 20. The air intake pipe 21 or the oil intake pipe 20 can also be cleaned while the detection is being carried out.

[0031] In this embodiment, a hinge bracket 11 and a support rod 10 are provided on the frame 1, and a detachable shaft rod 22 is provided on the end cover body 2. The shaft rod 22 can be placed in the hinge bracket 11. The support rod 10 is used to support one side of the end cover body 2, and the blocking part 14 is installed on the support rod 10.

[0032] Through the above-mentioned design scheme, when the end cover body 2 needs to be inspected, the staff only needs to install a shaft rod 22 at each end of the end cover body 2, and then place the end cover body 2 with the shaft rod 22 installed into the hinge bracket 11. The shaft rod 22 can rotate in the hinge bracket 11, which is convenient for the staff to flip the end cover body 2 for operation.

[0033] In this embodiment, an air pump 4 is provided on the frame 1, and the air pump 4 is connected to an air spray gun 40 through an air pipe, and a placement seat 41 for placing the air spray gun 40 is installed on the frame 1. The air pump 4 delivers high-pressure airflow to the air spray gun 40 through the air pipe. After the water pressure test, the water droplets remaining on the air inlet pipe 21, the oil inlet pipe 20 or the end cover body 2 will affect the subsequent processing, so the high-pressure airflow blown out by the air spray gun 40 is required to dry the remaining water droplets to avoid affecting the subsequent processing.

[0034] In this embodiment, a lifting assembly 5 is arranged above the frame 1, and the lifting assembly 5 includes a guide rail 50 and a slide 51. The slide 51 can slide on the guide rail 50, and a lifting ring 52 is arranged at the bottom of the slide 51, and a lifting rope 53 is arranged on the lifting ring 52; an auxiliary ring 23 is arranged on the end cover body 2, and the lifting rope 53 is connected to the auxiliary ring 23 through a buckle 54.

[0035] In this embodiment, the guide rail 50 can be suspended on the ceiling by means of suspension screws, or installed on the frame 1 by means of a bracket, and the slide seat 51 can lift the end cover body 2 by means of the auxiliary ring 23 for transportation; or the end cover body 2 can be lifted and rotated at the hinge bracket 11 until the end cover body 2 is in a vertical state, so as to facilitate the installation of the blocking portion 14 at the bottom of the end cover body 2.

[0036] In this embodiment, a water circulation component is provided on the frame 1, and the water circulation component includes a filter 32 and a return water tank 30. The return water tank 30 is provided below the end cover body 2, and the filter 32 is installed on the frame 1. The filter 32 is connected to the return water tank 30 and the high-pressure water pump 31 through a pipe 35 respectively.

[0037] Through the above design scheme, the water flow that has passed the pressure test flows from the air inlet pipe 21 or the oil inlet pipe 20 to the return water tank 30. The return water tank 30 collects the water flow and supplies it to the high-pressure water pump 31 through the pipe 35 and the filter 32. The filter 32 can filter the water flow in the return water tank 30 to prevent impurities from affecting the normal operation of the high-pressure water pump 31.

[0038] In this embodiment, an auxiliary lamp 12 and a main control unit 6 are provided on the frame 1. The auxiliary lamp 12 is used to illuminate the end cover body 2 in the frame 1, so as to facilitate the operation of the staff; the main control unit 6 is respectively connected to the high-pressure water pump 31, the air pump 4, the blocking unit 14, the auxiliary lamp 12 and the pressure detector, and the main control unit 6 can control these components respectively.
