Description

Technical Field

[0001] The present application relates to the technical field of oil cylinder detection equipment, and in particular to a locking oil cylinder leakage detection device. Background Art

[0002] At present, the oil cylinder, also known as the hydraulic cylinder, is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. However, oil cylinders often have leakage problems in actual applications. Leakage will lead to reduced efficiency and performance of the hydraulic system, and may even cause safety accidents in severe cases. Therefore, it is very important to detect and repair oil cylinder leakage in a timely manner.

The utility model adopts the cooperation of a hydraulic lifting cylinder, a load-bearing plate, a data transmission device, a connecting column, a pressure detection device and an extrusion plate, and can pressurize the inside of the hydraulic oil cylinder, and cooperate with the control data processing device to detect the change of pressure, so as to judge whether the oil cylinder has a leak.

[0004] The above-mentioned related technologies have the following defects: when leak detection is performed on the locking cylinder, it is usually necessary to pump hydraulic oil into the cylinder, and at the same time, it is determined whether new hydraulic oil needs to be replaced based on the quality of the hydraulic oil in the cylinder. The above-mentioned technical solution cannot perform these two tests at the same time, resulting in low maintenance efficiency of the locking cylinder. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0018] The present application embodiment discloses a locking cylinder leakage detection device. Figure 1 A locking oil cylinder leakage detection device includes a workbench 1, on which an oil storage tank 2, an oil pump 3 and an oil pipe 4 are arranged, and a pressure detection device 5 is arranged on the oil pipe 4, and the pressure detection device 5 is set as a pressure gauge or a pressure gauge; the workbench 1 is also provided with an oil return pipe 6 and an oil return tank 7, and the oil pipe 4 and the oil return pipe 6 are respectively provided with a first valve 41 and a second valve 61, and the pressure detection device 5 is arranged between the first valve 41 and the free end of the oil pipe 4. A transparent observation tube 8 is connected between the oil return pipe 6 and the oil return tank 7, and the transparent observation tube 8 is made of transparent hard plastic or transparent soft plastic, such as PEEK or silicone rubber.

[0019] When the technician is testing the locking cylinder, he moves the workbench 1 to the vicinity of the locking cylinder, and then aligns the oil pipe 4 and the return oil pipe 6 on the workbench 1 with the oil inlet and the oil outlet on the locking cylinder in sequence and tightens them, closes the second valve 61, opens the first valve 41 on the oil pipe 4, and then starts the oil pump 3, the hydraulic oil inside the oil storage tank 2 is transported to the locking cylinder, then closes the oil pump 3 and the first valve 41, and observes the pressure change in the oil pipe 4 through the pressure detection device 5 on the oil pipe 4, and then detects whether the locking cylinder is leaking. After the detection is completed, the second valve 61 on the oil outlet pipe can also be opened, at this time the original hydraulic oil in the locking cylinder flows out, the technician can observe and analyze the specific situation of the hydraulic oil inside the return oil pipe 6 through the transparent observation tube 8 between the return oil pipe 6 and the return oil tank 7, and can make a timely prediction through the transparent observation tube 8, that is, the hydraulic oil can be replaced in time, thereby improving the detection efficiency, and also enriching the detection function of the detection device of the present application.

[0020] Specifically, refer to Figure 1 A convex lens 81 is attached to the transparent observation tube 8, and a U-shaped portion is provided on the transparent observation tube 8. The convex lens 81 is provided on the horizontal section of the U-shaped portion. After such a setting, the convex lens 81 on the transparent observation tube 8 can be used for magnified observation, so that the sediment in the hydraulic oil can be more clearly seen; and after the U-shaped portion is provided on the transparent observation tube 8, the hydraulic oil can flow slowly in the horizontal section of the U-shaped portion. When there are sediments or particles in the original hydraulic oil in the locking oil cylinder, they can sink to the U-shaped portion, which is convenient for the inspection personnel to observe in time and perform oil change and maintenance on the locking oil cylinder.

[0021] In addition, refer to Figure 1 , the end of the transparent observation tube 8 away from the return oil pipe 6 is connected to a three-way control valve 82, one outlet of the three-way control valve 82 is connected to the return oil tank 7, and the other outlet is connected to the oil storage tank 2; after such arrangement, when the transparent observation tube 8 observes that the color of the hydraulic oil becomes turbid or particles are precipitated in the hydraulic oil, the three-way control valve 82 can be turned to the end connected to the return oil tank 7, and the hydraulic oil in the return oil pipe 6 flows to the return oil tank 7 and is abandoned for oil change maintenance; on the contrary, if the observed hydraulic oil is bright in color and free of particles, the three-way control valve 82 is turned to the end connected to the oil storage tank 2, and the hydraulic oil can flow back to the oil storage tank 2 and circulate into the locking cylinder again, thereby improving the efficiency of maintenance and inspection.

[0022] At the same time, refer to Figure 1 The oil delivery pipe 4 and the oil return pipe 6 are both hoses. A reel 9 for reeling in the oil delivery pipe 4 and the oil return pipe 6 is installed on the workbench 1, and a roller 10 is installed at the bottom of the workbench 1. After such arrangement, when the technicians have completed the maintenance and inspection of the locking cylinder, the hoses can be neatly rolled up to avoid the oil delivery pipe 4 and the oil return pipe 6 being messy and unsightly, while also facilitating their unfolding at the next work, thereby improving work efficiency and safety. In addition, the roller 10 at the bottom of the workbench 1 allows the workbench 1 to slide freely on a plane, making it easy to operate at different positions.

[0023] The implementation principle of a locking cylinder leakage detection device in the embodiment of the present application is as follows:

[0024] When the technician is testing the locking cylinder, he moves the workbench 1 to the vicinity of the locking cylinder, and then aligns the oil pipe 4 and the return oil pipe 6 on the workbench 1 with the oil inlet and the oil outlet on the locking cylinder in sequence and tightens them, closes the second valve 61, opens the first valve 41 on the oil pipe 4, and then starts the oil pump 3, the hydraulic oil inside the oil storage tank 2 is transported to the locking cylinder, then closes the oil pump 3 and the first valve 41, and observes the pressure change in the oil pipe 4 through the pressure detection device 5 on the oil pipe 4, and then detects whether the locking cylinder is leaking. After the detection is completed, the second valve 61 on the oil outlet pipe can also be opened, at this time the original hydraulic oil in the locking cylinder flows out, the technician can observe and analyze the specific situation of the hydraulic oil inside the return oil pipe 6 through the transparent observation tube 8 between the return oil pipe 6 and the return oil tank 7, and can make a timely prediction through the transparent observation tube 8, that is, the hydraulic oil can be replaced in time, thereby improving the detection efficiency, and also enriching the detection function of the detection device of the present application.
