DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0029] Please refer to Figures 1-9One embodiment of the present invention is: an electrical control cabinet for a hydraulic pipeline assembly airtightness test bench, comprising a device body 1, a square slot being provided on the right side of the device body 1, an electrical component 2 being provided inside the device body 1, a plurality of electrical wires 21 being provided at the bottom of the electrical component 2, a heat dissipation component 3 being provided at the top of the device body 1, and the heat dissipation component 3 being communicated with the interior of the device body 1, an airtightness detection component 31 being provided on the left side of the device body 1, a fixed plate 6 being fixedly installed at the bottom of the device body 1, and the top of the fixed plate 6 being in contact with the bottom of the airtightness detection component 31, electric push rods 7 being fixedly installed at the four corners of the bottom of the fixed plate 6, the electric push rod 7 being composed of a telescopic end and a fixed end, and the top of the telescopic end of the electric push rod 7 being fixedly installed at the bottom of the fixed plate 6, a bearing plate 8 being fixedly installed at the bottom of the fixed end of the electric push rod 7, a drive disk 9 being provided at the bottom of the bearing plate 8, and an inclined plate 10 being hinged at the top edge of the bearing plate 8. The inclined plate 10 is hinged with a pull plate 11 on one side of the outer wall of the device body 1, and the top of the pull plate 11 is hinged at the bottom edge of the fixed plate 6. The inclined surface of the inclined plate 10 is hinged with a pressure plate 12 on one side of the outer wall of the device body 1, and a gravity block 13 is hinged at the bottom of the pressure plate 12. The bottom plane of the gravity block 13 is fixedly installed at the top center of the load-bearing plate 8. Through the above cooperation, the orientation of the airtight detection component 31 is constantly changing during the test of the hydraulic pipeline assembly to adapt to the actual situation that the pipeline is easily affected by external interference and a certain amount of pulling in actual application, thereby ensuring that the data of the airtight detection is more in line with reality and at the same time testing the durability of the hydraulic pipeline assembly; through the above cooperation, vertical downward stability is provided for the device body 1 and the airtight detection component 31 during the test, avoiding external interference causing the equipment to shake, causing the hydraulic pipeline assembly to be pulled by external force, thereby reducing the accuracy of the test data.

[0030] The driving disk 9 has a built-in motor, and the top of the motor output end passes through and is fixedly installed on the bottom of the load-bearing plate 8. The pressure plate 12 is located below the pull plate 11. A sealing device 4 is provided inside the device body 1 to prevent external moisture from entering the device body 1 when the hydraulic pipeline is subjected to air tightness testing.

[0031] When in use, the hydraulic pipeline assembly is placed inside the airtight detection component 31 and one end of the hydraulic pipeline assembly is fixed in the detection pool. The airtight detection component 31 is started by the electrical component 2 and the test value is set according to the test requirements. The hydraulic pipeline assembly is observed to see whether it leaks and produces bubbles in the detection pool to record the test data, and the heat dissipation component 3 is used to dissipate heat inside the device body 1 to prevent the temperature from being too high. In order to make the test data more in line with reality, the control cabinet controls the built-in motor of the drive disk 9 to start, and the output end of the motor drives the load-bearing plate 8 to rotate. When the load-bearing plate 8 rotates, it drives the electric push rod 7 to move synchronously. The electric push rod 7 drives the fixed plate 6 to rotate, and the fixed plate 6 drives the device body 1 and the airtight detection component 31 to rotate, thereby forming a rotational pulling force on the hydraulic pipeline assembly. At the same time, the electric push rod 7 is started, and the telescopic end of the electric push rod 7 pushes the device body 1 upward. The device body 1 prompts the airtight detection component 31 to drive the hydraulic pipeline assembly to rise synchronously, thereby while the hydraulic pipeline assembly is subjected to the rotational pulling force It will also withstand upward pulling force. Through the above cooperation, the orientation of the airtight detection component 31 is constantly changed during the test of the hydraulic pipeline assembly, so as to adapt to the actual situation that the pipeline is easily affected by external interference and a certain amount of pulling in actual application, thereby ensuring that the airtight detection data is more in line with reality and at the same time testing the durability of the hydraulic pipeline assembly; when the fixed plate 6 rises, the inclined plate 10 is pulled synchronously by the pulling plate 11. At this time, the hinge axis between the inclined plate 10 and the load-bearing plate 8 begins to rotate, and the inclined plate 10 deviates toward the center of the device body 1. The inclined plate 10 drives the pressure plate 12 to move synchronously, and the hinge axis between the pressure plate 12 and the gravity block 13 begins to rotate. At this time, the pressure plates 12 on both sides apply vertical downward pressure to the gravity block 13 in the shape of an isosceles triangle. Through the above cooperation, vertical downward stability is provided for the device body 1 and the airtight detection component 31 during the test, avoiding external interference causing the equipment to shake, causing the hydraulic pipeline assembly to be pulled by external force, thereby reducing the accuracy of the test data.

[0032] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes a sealing device 4;

[0033] The sealing device 4 includes a vertical rod 41, a horizontal plate 42, a telescopic sealing plate 43 and a resistance block 44. The bottom of the vertical rod 41 is fixedly installed at the top edge of the load-bearing plate 8, and the top of the vertical rod 41 is movable through the inside of the device body 1. The left side of the horizontal plate 42 is fixedly installed on the right side of the outer wall of the vertical rod 41. The outer wall of the telescopic sealing plate 43 is fixedly installed on the inner wall of the square groove of the device body 1. The telescopic sealing plate 43 consists of a telescopic end and a fixed end. The right side of the resistance block 44 is fixedly installed on the left side of the telescopic end of the telescopic sealing plate 43. The top of the resistance block 44 contacts the bottom of the horizontal plate 42. Through the above cooperation, the hydraulic pipeline assembly is prevented from constantly disturbing the water flow inside the detection pool during the airtightness detection, increasing the humidity around the device body 1, and preventing moisture from passing through the square groove into the inside of the device body 1, causing water vapor to erode internal circuits such as the electrical wire 21, thereby increasing the risk of short circuit.

[0034] The sealing device 4 also includes a transmission plate 45, a push plate 46, a sliding ring 47, a rotating rod 48 and a low-temperature component 49. The top of the transmission plate 45 is hinged to the left side of the telescopic end of the telescopic sealing plate 43, and the right side of the push plate 46 is hinged to the bottom of the transmission plate 45. The bottom of the push plate 46 is slidably installed on the bottom of the inner wall of the device body 1, and the right side of the sliding ring 47 is fixedly installed at the center of the left side of the push plate 46. The left end of the rotating rod 48 is rotatably installed on the left side of the inner wall of the device body 1, and the outer wall of the rotating rod 48 is located inside the sliding ring 47. The right side of the low-temperature component 49 is fixedly installed on the left side of the push plate 46. The above cooperation expands the cold air diffusion range of the low-temperature component 49 to prevent the cold air emitted from the low-temperature component 49 at a fixed point from mixing rapidly with the heat of the equipment to generate a large amount of fog that fills the inside of the device body 1 and blocks the line of sight of the inspector, which easily leads to a certain deviation in the recorded test data by the inspector and requires a second test.

[0035] The outer wall of the rotating rod 48 passes through the inside of the push plate 46. A spiral groove is provided on the left side of the outer wall of the rotating rod 48, and the spiral groove is located on the movement trajectory of the sliding ring 47. An anti-oxidation device 5 is provided on the right side of the outer wall of the rotating rod 48 to prevent the heat generated by the internal equipment of the device body 1 during operation from mixing with the water vapor generated by the cold air of the low-temperature component 49 to accelerate the oxidation of the rubber skin on the surface of the electrical wire 21.

[0036] When in use, the device body 1 moves upward, driving the telescopic sealing plate 43 to move synchronously, and the telescopic end of the telescopic sealing plate 43 moves upward, driving the resistance block 44 to move synchronously, and the resistance block 44 contacts the horizontal plate 42 when it moves upward. The horizontal plate 42 is limited by the vertical rod 41 and remains stationary. At this time, the square groove of the device body 1 drives the fixed end of the telescopic sealing plate 43 to continue to move, while the telescopic end of the telescopic sealing plate 43 remains stationary and extends from the inside of the telescopic sealing plate 43. At this time, the telescopic sealing plate 43 blocks the square groove of the device body 1 to form a relatively sealed environment. Through the above cooperation, the hydraulic pipeline assembly is prevented from constantly disturbing the water flow inside the detection pool during the airtightness detection, increasing the humidity around the device body 1, and preventing moisture from entering the device body 1 through the square groove, causing water vapor to erode internal circuits such as the electrical wires 21, thereby increasing the risk of short circuit; the telescopic end of the telescopic sealing plate 43 limits the transmission plate 45, and when the transmission plate 45 is stationary, the device body 1 drives The upward movement of the push plate 46 forms a resistance force on the transmission plate 45. At this time, the hinge shaft between the transmission plate 45 and the push plate 46 begins to rotate and the transmission plate 45 pushes the push plate 46 to slide to the left along the bottom of the inner wall of the device body 1. The push plate 46 drives the sliding ring 47 to slide along the outer wall of the non-self-locking spiral groove on the left side of the rotating rod 48. The restriction of the spiral groove on the sliding ring 47 and the continuous resistance of the internal block of the sliding ring 47 to the inner wall of the spiral groove cause the rotating rod 48 to start rotating. At the same time, the push plate 46 drives the low-temperature component 49 to slide to the left to release cold air and mix it with the heat inside the device body 1, and then it is extracted from the inside of the device body 1 through the heat dissipation component 3. The above cooperation expands the cold air diffusion range of the low-temperature component 49, prevents the cold air emitted by the low-temperature component 49 at a fixed point from mixing rapidly with the heat of the equipment to generate a large amount of fog that fills the inside of the device body 1 and blocks the line of sight of the inspector, which easily causes the inspector to have a certain deviation in the recorded test data and requires a second test.

[0037] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-oxidation device 5;

[0038] The anti-oxidation device 5 includes a ring 51, a transmission ring 52, an L-shaped plate 53, a groove plate 54 and several swing plates 55. The inner wall of the ring 51 is fixedly mounted on the outer wall of the rotating rod 48, the inner wall of the transmission ring 52 is sleeved and slidably mounted on the outer wall surface of the ring 51, the top of the L-shaped plate 53 is fixedly mounted on the bottom of the outer wall of the transmission ring 52, the bottom of the L-shaped plate 53 is slidably connected to the bottom of the inner wall of the device body 1, the front of the groove plate 54 is fixedly mounted on the back of the L-shaped plate 53, and the backs of several swing plates 55 are all hinged to the back of the inner wall of the device body 1. The above cooperation with the swing plate 55 prevents moisture or fog from floating around the electrical wire 21 and liquefying into water droplets attached to the outside of the rubber skin of the line, and blocks the water vapor generated by the mixture of cold and hot air flows to prevent the oxidation rate of the surface of the electrical wire 21 and other lines from accelerating and causing the line to be exposed.

[0039] The outer wall of the sleeve ring 51 is provided with reciprocating spiral grooves, the inner wall of the transmission ring 52 is in contact with the reciprocating spiral grooves of the outer wall of the sleeve ring 51, and the swing plates 55 are located adjacent to the electrical wires 21.

[0040] The anti-oxidation device 5 further comprises a plurality of moisture-proof plates 56, a sliding groove plate 57, a sliding rod 58 and a friction column 59. The plurality of moisture-proof plates 56 are equidistantly and fixedly installed on the outer wall right side of the rotating rod 48. The sliding groove plate 57 is fixedly installed on the outer wall right side of the transmission ring 52. The left end of the sliding rod 58 is slidingly installed in the sliding groove plate 57, and a spring is arranged between the sliding rod 58 and the sliding groove plate 57. The inner wall of the friction column 59 penetrates and is fixedly installed on the outer wall of the sliding rod 58, and the friction column 59 is located on the movement track of the moisture-proof plate 56. Through the above cooperation, the moisture-proof plate 56 is used to rotate and absorb the water vapor deposited at the lower part of the inside of the device main body 1, so as to ensure that the inside of the device main body 1 has good drying effect. At the same time, the friction column 59 is used to rub the water droplets attached to the outer wall of the moisture-proof plate 56 in multiple directions, so as to expand the contact area of the water droplets on the outer wall of the moisture-proof plate 56, accelerate the air-drying or absorption speed of the water droplets, and further prevent the precision equipment in the device main body 1 from being oxidized by the water vapor, thereby increasing the maintenance cost.

[0041] When in use, the rotation of the rotating rod 48 drives the ring 51 to rotate. When the ring 51 rotates, the reciprocating spiral groove on its outer wall restricts the transmission ring 52, and the built-in block of the transmission ring 52 continuously contacts the inner wall of the reciprocating spiral groove, so that the transmission ring 52 can slide back and forth along the outer wall of the ring 51. The transmission ring 52 drives the L-shaped plate 53 to move synchronously, and the L-shaped plate 53 drives the groove plate 54 to slide synchronously along the bottom of the inner wall of the device body 1. When the groove plate 54 slides, the inner wall of the groove on the back of the groove continuously contacts the swing plate 55. The arc surface, at this time, the hinge shaft between the swing plate 55 and the inner wall of the device body 1 starts to rotate, causing the swing plate 55 to swing back and forth between the adjacent electrical wires 21. By cooperating with the swing plate 55, moisture or fog is prevented from floating around the electrical wires 21 and liquefying into water droplets attached to the outside of the rubber surface of the line, and the water vapor generated by the mixing of cold and hot air flows is blocked to prevent the electrical wires 21 and other lines from being exposed due to accelerated oxidation rate of the surface; when the rotating rod 48 rotates, it drives the moisture-proof plate 56 to rotate, and when the moisture-proof plate 56 rotates, it will contact the friction The friction column 59 is moved along the outer wall of the sliding plate 56 by the friction force generated by the rotation of the moisture-proof plate 56 and the guiding force of the arc, so that the sliding rod 58 can slide along the inner wall of the sliding groove plate 57 away from the center of the rotating rod 48. When the moisture-proof plate 56 no longer resists the friction column 59, the sliding rod 58 is reset by the spring force, and the friction column 59 is reset. At the same time, the friction column 59 can slide left and right through the transmission ring 52 to rub the outer wall of the moisture-proof plate 56. Through the above cooperation, the moisture-proof plate 56 is rotated to absorb the water vapor easily deposited at the lower part of the internal part of the device body 1, so as to ensure that the internal part of the device body 1 has a good drying effect. At the same time, the friction column 59 rubs the water droplets attached to the outer wall of the moisture-proof plate 56 in multiple directions, thereby expanding the contact area of ​​the water droplets on the outer wall of the moisture-proof plate 56 to accelerate its drying or absorption speed, and further prevent the precision equipment inside the device body 1 from being attached by water vapor and accelerated oxidation, thereby increasing maintenance costs.
