During the observation, it is necessary to manually patrol around carefully, which may inevitably lead to carelessness and omissions. In addition, when sealing the cylinder mouth, it is necessary to dock the sealing sleeve. If the sealing sleeve is not tightened, it will affect the sealing test result, so it needs to be improved.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model is provided with a bubble observation device, which is conducive to filling water into the glass water cylinder, making the water level higher than the cylinder mouth of the cylinder body, observing whether there are bubbles to judge whether the cylinder mouth is sealed and docked, and driving the C-shaped frame downward by the hydraulic cylinder to move the cylinder body in the clamping plate downward, and squeeze and dock with the sealing rubber plate, and start the second water pump to pump water in the water tank into the glass water cylinder. Because the water storage in the water tank is equal to the water demand of the glass water cylinder, the water level of the glass water cylinder can be higher than the sealing position of the cylinder mouth of the cylinder body, and through the perspective of the glass water cylinder, it is observed whether there are bubbles, so it can be judged whether the cylinder mouth is sealed and docked;

Because the air supply pipe and the sealing rubber plate are connected by a movable joint, the sealing rubber plate can be tilted at an angle, and the inclined cylinder oil cylinder port can also be squeezed and docked. After the docking is completed, the air pump inputs gas and pressurizes it, and transmits it into the middle through hole of the sealing rubber plate through the air supply pipe, so as to pressurize the oil cylinder port with gas.

DETAILED DESCRIPTION

[0025] 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 them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field of sealing detection without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and 2As shown, the utility model provides a cylinder sealing detection device, including a casing 1: a glass water cylinder 11 is fixedly provided on the inner side of the casing 1, a supporting slide plate 12 is movably provided in a groove on the inner side of the casing 1, a switch door 4 is movably connected to one side of the casing 1 through a hinge, a hydraulic cylinder 5 is penetrated through the upper end of the casing 1, a C-shaped frame 7 is fixedly provided on the output end of the hydraulic cylinder 5, threaded rods 8 are respectively penetrated on both sides of the C-shaped frame 7, the outer surface of the threaded rod 8 is threadedly connected with the inner side of the C-shaped frame 7, a rotating handle 6 is fixedly provided at one end of the threaded rod 8, a clamping plate 9 is fixedly provided at the other end of the threaded rod 8, a limiting slide rod 10 is fixedly provided on one side of the clamping plate 9, and the limiting slide rod 10 penetrates one side of the C-shaped frame 7.

[0027] In order to determine whether the oil cylinder mouth is sealed and docked, a bubble observation device 2 capable of pouring water into the glass water cylinder 11 is provided on one side of the housing 1, which is used to pour water into the glass water cylinder 11 so that the water level is higher than the oil cylinder mouth of the cylinder body, and observe whether there are bubbles to determine whether the oil cylinder mouth is sealed and docked;

[0028] like Figure 3 As shown, the bubble observation device 2 includes a water tank 21, which is fixedly arranged on one side of the casing 1. A first water pump 22 and a second water pump 23 are fixedly arranged at the lower end of the water tank 21, respectively. One side of the glass water cylinder 11 is connected with two water pipes 24, which penetrate one side of the inner wall of the casing 1, and are fixedly connected to the output end of the second water pump 23 and the input end of the first water pump 22, respectively. Receiving grooves 25 are provided on both side walls of the upper end of the glass water cylinder 11. The C-shaped frame 7 is pressed downward by the hydraulic cylinder 5, so that the cylinder body in the clamping plate 9 is moved downward and squeezed and docked with the sealing rubber plate 31. The second water pump 23 is started to pump the water in the water tank into the glass water cylinder 11. Because the amount of water in the water tank 21 is equal to the water demand of the glass water cylinder 11, the water level of the glass water cylinder 11 can be higher than the sealing position of the cylinder oil cylinder mouth. Through the perspective of the glass water cylinder 11, it is observed whether bubbles appear, so it can be judged whether the oil cylinder mouth is sealed and docked.

[0029] Furthermore, in order to determine whether the cylinder body is sealed, a leak detection device 3 capable of sealingly docking with the cylinder body oil cylinder port is provided on the inner side of the glass water cylinder 11, which is used to seal and dock with the cylinder body oil cylinder port and supply gas to the oil cylinder port for pressurization;

[0030] like Figure 4As shown, the pressure leakage detection device 3 includes an air filter 36, which is fixedly arranged at the lower end of one side of the casing 1, an air pipe 33 is fixedly arranged on one side of the air filter 36, a one-way valve 34 and an air pump 35 are fixedly arranged in the middle section of the air pipe 33, an active joint 32 is fixedly arranged on the upper end of the air pipe 33, a pressure gauge 37 is connected to one side of the air pipe 33, and a sealing rubber plate 31 is connected to the upper end of the active joint 32. By pressing down the hydraulic cylinder 5, the cylinder port of the cylinder body is connected to the sealing rubber plate 31, thereby squeezing and sealing. The plates 31 are connected by a movable joint 32, so that the sealing rubber plate 31 can be tilted at an angle, and the tilted cylinder oil cylinder port can also be squeezed and docked. After the docking is completed, the air pump 35 inputs gas and pressurizes it, and transmits it to the middle through hole of the sealing rubber plate 31 through the air pipe 33, so as to pressurize the gas at the oil cylinder port. After the pressurization is completed, the air pump 35 is turned off, and the one-way valve 34 can effectively prevent gas backflow. After the pressurization is completed, observe the changes in the pressure gauge 37. When the value of the pressure gauge 37 drops rapidly, it can be judged that the cylinder sealing is unqualified.

[0031] The working principle is as follows: when the utility model is in use, the switch door 4 is opened, the supporting slide 12 is inserted, and the cylinder body is pushed on the supporting slide 12 into the C-shaped frame 7. By rotating the rotating handle 6 and cooperating with the limiting slide bar 10, the two clamping plates 9 can clamp the cylinder body. After the clamping is completed, the supporting slide 12 is pulled out, and the hydraulic cylinder 5 is started to press down, and the cylinder body is pressed down to the sealing rubber plate 31 for docking. Because the upper end of the glass water cylinder 11 is provided with a storage groove 25, the threaded rod 8 and the rotating handle 6 are stored. After the sealed docking, the bubble observation device 2 can be used to observe the bubbles to determine whether the docking is sealed, and then the leakage pressure detection device 3 performs a pressurization test, and the cylinder body sealing is determined by observing the changes in the barometer 37.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
