[0004] However, the device still has some shortcomings: the device can dissipate heat and dry the inside of the cabinet, but in the airtight test of the hydraulic pipeline, the position of the airtight test component is fixed, and in the actual application of the pipeline, the pipeline is easily affected by external interference and causes a certain position deviation. Therefore, the cabinet should be adjusted appropriately to ensure that the airtight test data is more in line with reality. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an electrical control cabinet for a hydraulic pipeline assembly airtight test bench, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: an electrical control cabinet for a hydraulic pipeline assembly airtight test bench, comprising a device body, a square groove is arranged on the right side of the device body, an electrical component is arranged inside the device body, a plurality of electrical wires are arranged at the bottom of the electrical component, a heat dissipation component is arranged on the top of the device body, and the heat dissipation component is communicated with the inside of the device body, an airtight detection component is arranged on the left side of the device body, a fixing plate is fixedly installed at the bottom of the device body, and the top of the fixing plate is in contact with the bottom of the airtight detection component, and electric A push rod, the electric push rod is composed of a telescopic end and a fixed end, and the top of the telescopic end of the electric push rod is fixedly installed on the bottom of the fixed plate, and a load-bearing plate is fixedly installed on the bottom of the fixed end of the electric push rod, and a driving disk is arranged at the bottom of the load-bearing plate, and an inclined plate is hinged at the top edge of the load-bearing plate, and a pull plate is hinged at the side of the inclined plate close to the outer wall of the device body, and the top of the pull plate is hinged at the bottom edge of the fixed plate, and a pressure plate is hinged at the inclined surface of the side of the inclined plate close to the outer wall of the device body, and a gravity block is hinged at the bottom of the pressure plate, and the bottom plane of the gravity block is fixedly installed at the center of the top of the load-bearing plate, and the hydraulic pipeline assembly is placed in the airtight inspection The inside of the test component is fixed with one end of the hydraulic pipeline assembly in the test pool, the airtight test component is started through the electrical component and the test value is set according to the test requirements, and the hydraulic pipeline assembly is observed to see whether there is air leakage in the test pool to produce bubbles to record the test data, and the heat dissipation component is used to dissipate heat inside the device body to prevent the temperature from being too high; in order to make the test data more realistic, the built-in motor of the drive disk is started, and the output end of the motor drives the load-bearing plate to rotate, and the rotation of the load-bearing plate drives the electric push rod to move synchronously, and the electric push rod drives the fixed plate to rotate, and the fixed plate drives the device body and the airtight test component to rotate, thereby testing the hydraulic pipeline assembly. A rotational pulling force is generated, and the electric push rod is started at the same time. The telescopic end of the electric push rod pushes the device body to move upward, and the device body prompts the airtight detection component to drive the hydraulic pipeline assembly to rise synchronously. As a result, the hydraulic pipeline assembly is subjected to an upward pulling force while also subjected to a rotational pulling force. When the fixed plate rises, the inclined plate is pulled to move synchronously by the pulling plate. At this time, the hinge shaft between the inclined plate and the load-bearing plate begins to rotate, and the inclined plate deviates toward the center of the device body. The inclined plate drives the pressure plate to move synchronously, and the hinge shaft between the pressure plate and the gravity block begins to rotate. At this time, the pressure plates on both sides apply vertical downward pressure to the gravity block in the shape of an isosceles triangle.

[0007] According to the above technical solution, the driving disk 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. The pressure plate is located below the pull plate. A sealing device is provided inside the device body to prevent external moisture from entering the device body when the hydraulic pipeline is subjected to air tightness testing.

[0008] According to the above technical scheme, the sealing device includes a vertical rod, a horizontal plate, a telescopic sealing plate and a resistance block, the bottom of the vertical rod is fixedly installed at the top edge of the load-bearing plate, the top of the vertical rod movably passes through the inside of the device body, the left side of the horizontal plate is fixedly installed on the right side of the outer wall of the vertical rod, the outer wall of the telescopic sealing plate is fixedly installed on the inner wall of the square groove of the device body, the telescopic sealing plate is composed of a telescopic end and a fixed end, the right side of the resistance block is fixedly installed on the left side of the telescopic end of the telescopic sealing plate, and the top of the resistance block contacts with the bottom of the horizontal plate. When the device body moves upward, it drives the telescopic sealing plate to move synchronously, and when the telescopic end of the telescopic sealing plate moves upward, it drives the resistance block to move synchronously. When the resistance block moves upward, it will contact the horizontal plate, and the horizontal plate is limited by the vertical rod and remains stationary. At this time, the square groove of the device body drives the fixed end of the telescopic sealing plate to continue moving, while the telescopic end of the telescopic sealing plate remains stationary and extends from the inside of the telescopic sealing plate. At this time, the telescopic sealing plate blocks the square groove of the device body to form a relatively sealed environment.

The left end of the cam is rotatably mounted on the left side of the inner wall of the device body, and the outer wall of the cam is located inside the sliding ring. The right side of the cam is fixedly mounted on the left side of the pushing plate. The telescopic end of the telescopic sealing plate limits the transmission plate. When the transmission plate is stationary, the device body drives the pushing plate to move upward to form a resistance force on the transmission plate. At this time, the hinge shaft between the transmission plate and the pushing plate starts to rotate and the transmission plate pushes the pushing plate to slide to the left along the bottom of the inner wall of the device body. The pushing plate drives the sliding ring to slide along the outer wall of the non-self-locking spiral groove on the left side of the rotating rod. The restriction of the spiral groove on the sliding ring and the continuous resistance of the internal block of the sliding ring to the inner wall of the spiral groove cause the rotating rod to start rotating. At the same time, the pushing plate drives the low-temperature component to slide to the left to dissipate cold air and mix it with the heat inside the device body, and then extract it from the inside of the device body through the heat dissipation component.

[0010] According to the above technical solution, the outer wall of the rotating rod passes through the inside of the push plate, a spiral groove is provided on the left side of the outer wall of the rotating rod, and the spiral groove is located on the movement trajectory of the sliding ring, and an anti-oxidation device is provided on the right side of the outer wall of the rotating rod to prevent the heat generated when the equipment inside the device body is running and the water vapor generated after mixing with the cold air of the low-temperature component to accelerate the oxidation of the rubber skin on the surface of the electrical wire.

[0012] According to the above technical solution, a reciprocating spiral groove is opened on the outer wall of the ring, the inner wall of the transmission ring contacts the reciprocating spiral groove of the outer wall of the ring, and several swing plates are located adjacent to the electrical wires, and the front side of the swing plate is located on the movement trajectory of the groove plate.

[0013] The cam is provided with a plurality of spring plates, a plurality of spring plates and a plurality of spring plates, and the spring plates are provided with a plurality of spring plates at a plurality of intervals so as to prevent the plurality of spring plates from sliding and rubbing against each other.

[0014] The present invention provides an electrical control cabinet for a hydraulic pipeline assembly airtight test bench, which has the following beneficial effects:

[0015] (1) The present invention coordinates a fixed plate, an electric push rod, a load-bearing plate, a drive plate, an inclined plate, a pulling plate, a pressing plate and a gravity block to cause the position of the airtight detection component to change continuously during the test of the hydraulic pipeline assembly, so as to adapt to the actual situation that the pipeline is easily disturbed by the outside world and is pulled to a certain extent in actual application, thereby ensuring that the airtight detection data is more in line with reality and testing the durability of the hydraulic pipeline assembly; at the same time, it provides vertical downward stability for the device body and the airtight detection component 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.

[0016] (2) The present invention adopts the setting of a sealing device, and cooperates with vertical rods, horizontal plates, telescopic sealing plates, abutment blocks, transmission plates, push plates, sliding rings, rotating rods and low-temperature components to avoid the hydraulic pipeline assembly from constantly disturbing the water flow inside the detection pool during the air-tightness detection, increasing the humidity around the device body, and preventing moisture from entering the device body through the square groove, causing water vapor to corrode internal circuits such as electrical wires, thereby increasing the risk of short circuits; and expanding the cold air diffusion range of the low-temperature component to prevent the cold air emitted from the low-temperature component at a fixed point from mixing rapidly with the heat of the equipment to generate a large amount of fog that permeates the inside of the device body and blocks the line of sight of the inspectors, which may easily lead to a certain deviation in the recorded test data by the inspectors and require a secondary test.

[0017] (3) The present invention sets an anti-oxidation device, and cooperates with a rotating rod, a sleeve ring, a transmission ring, an L-shaped plate, a groove plate, a swing plate, a moisture-proof plate, a slide plate, a sliding rod and a friction column, so that the swing plate prevents moisture or fog from floating around the electrical wire and liquefying into water droplets attached to the outside of the rubber surface of the line, and shields 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 and other lines from accelerating and causing the line to be exposed; at the same time, the moisture-proof plate is prompted to rotate and absorb the water vapor that is easily deposited at the lower part of the inside of the device body, thereby ensuring that the inside of the device body has a good drying effect. At the same time, the friction column rubs the water droplets attached to the outer wall of the moisture-proof plate in multiple directions, thereby expanding the contact area of ​​the water droplets on the outer wall of the moisture-proof plate and accelerating its drying or absorption speed, further preventing the precision equipment inside the device body from being accelerated by the attachment of water vapor and oxidation, thereby increasing the maintenance cost.

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 changed during the test of the hydraulic pipeline assembly to adapt to the actual situation that the pipeline is easily disturbed by the outside world and is pulled to a certain extent in actual applications, 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, so as to avoid external interference causing the equipment to shake and 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 tested for air tightness.

[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, and whether the hydraulic pipeline assembly leaks in the detection pool to produce bubbles 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, and the load-bearing plate 8 rotates and drives the electric push rod 7 to move synchronously, and 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, and at the same time starting the electric push rod 7, the telescopic end of the electric push rod 7 pushes the device body 1 to move upward, and 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 to adapt to the actual situation that the pipeline is easily disturbed by the outside world and is pulled to a certain extent in actual application, thereby ensuring that the data of the airtight detection is more in line with reality and at the same time detecting 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.

[0032] See also Figure 1-Figure 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, 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 is composed 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, and 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 airtight 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, 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, 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, and 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 fixed point of the low-temperature component 49 from mixing rapidly with the heat of the equipment to generate a large amount of fog that permeates 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 secondary test.

[0035] The outer wall of the rotating rod 48 passes through the push plate 46, and 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 when the internal equipment of the device body 1 is running and the water vapor generated after mixing with 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. The telescopic end of the telescopic sealing plate 43 moves upward, driving the resistance block 44 to move synchronously. 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 water flow inside the detection pool is prevented from being constantly disturbed during the air-tightness detection of the hydraulic pipeline assembly, 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 push plate 46 moves upward to form 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 spiral groove restricts the sliding ring 47 and the internal block of the sliding ring 47 continuously resists the inner wall of the spiral groove, causing 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 emit cold air and mix with the internal heat of the device body 1, and then extract it 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 with the heat of the equipment rapidly 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 secondary test.

[0037] See also Figure 1-Figure 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 collar 51, a transmission ring 52, an L-shaped plate 53, a groove plate 54 and a plurality of swing plates 55. The inner wall of the collar 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 collar 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 the plurality of swing plates 55 are 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 skin of the electrical wire 21 and other lines from accelerating and causing the line to be exposed.

[0039] The outer wall of the ring 51 is provided with a reciprocating spiral groove, the inner wall of the transmission ring 52 is in contact with the reciprocating spiral groove of the outer wall of the ring 51, and a plurality of swing plates 55 are located adjacent to the electrical wire 21, and the front side of the swing plate 55 is located on the movement track of the groove plate 54.

[0040] The anti-oxidation device 5 also includes a plurality of moisture-proof plates 56, a slide plate 57, a sliding rod 58 and a friction column 59. The plurality of moisture-proof plates 56 are equidistant and fixedly mounted on the right side of the outer wall of the rotating rod 48. The left side of the slide plate 57 is fixedly mounted on the right side of the outer wall of the transmission ring 52. The left end of the sliding rod 58 is slidably mounted inside the slide plate 57, and a spring is arranged between the sliding rod 58 and the inside of the slide plate 57. The inner wall of the friction column 59 passes through and is fixedly mounted on the outer wall of the sliding rod 58, and the friction column 59 is located on the movement trajectory of the moisture-proof plate 56. Through the above cooperation, the moisture-proof plate 56 is driven to rotate and absorb the water vapor easily deposited at the lower part of the inside of the device body 1, so as to ensure that the inside of the device body 1 has a good drying effect. At the same time, the friction column 59 performs multi-directional friction on the water droplets attached to the outer wall of the moisture-proof plate 56, 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 accelerating oxidation, thereby increasing the maintenance cost.

[0041] When in use, the rotating rod 48 rotates to drive the collar 51 to rotate. When the collar 51 rotates, the reciprocating spiral groove on its outer wall restricts the transmission ring 52, and the built-in block in the transmission ring 52 continuously contacts the inner wall of the reciprocating spiral groove to enable the transmission ring 52 to slide back and forth along the outer wall of the collar 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 swing plate 55 is connected to the inner wall of the device body 1 and the hinge shaft 56 starts to rotate, so that the swing plate 55 swings back and forth between the adjacent electric wires 21. The swing plate 55 prevents moisture or fog from floating around the electric wires 21 and liquefying into water droplets attached to the outside of the rubber surface of the line, and shields the water vapor generated by the mixture of cold and hot air flows to prevent the electric wires 21 and other lines from being exposed due to the accelerated oxidation rate of the line 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 outer wall of the rubbing column 59 generates friction, and the sliding rod 58 limits the friction column 59 at this time, so that the arc-shaped outer wall of the moisture-proof plate 56 slides and rubs along the outer wall of the friction column 59. The friction column 59 drives the sliding rod 58 to slide along the inside of the slide groove plate 57 away from the center of the rotating rod 48 through the resistance force generated by the rotation of the moisture-proof plate 56 and the arc-shaped guiding force. When the moisture-proof plate 56 no longer resists the friction column 59, the sliding rod 58 drives the friction column 59 to reset when it is reset by the spring force. At the same time, the friction column 59 realizes left and right sliding friction on the outer wall of the moisture-proof plate 56 through the transmission ring 52. Through the above cooperation, the moisture-proof plate 56 is caused to rotate and absorb the water vapor easily deposited at the lower part of the inside of the device body 1, so as to ensure that the inside 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 accelerating oxidation, thereby increasing the maintenance cost.
