The cause of the unstable oil pressure can be determined by whether there is hydraulic oil flowing down. In addition, when the hydraulic oil leaks, it can be determined whether the leak occurs at the oil outlet pipe or the oil inlet pipe, so as to facilitate the maintenance of the hydraulic power equipment;

[0017] 3. An auxiliary detection structure is provided, which can make the cleaning ring and the cleaning scraper move up and down and rotate, scrape the hydraulic oil from the leaking place, so that it can quickly flow into the detection frame and be absorbed by the oil absorption plate, thereby speeding up the detection speed of the device, and can quickly complete the detection of hydraulic power equipment, which is conducive to the detection.

DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 9 A hydraulic power detection device for mechanical testing equipment includes a workbench 1, a fixed bracket 2, a detection frame 5 and a fixed box 6 are fixedly installed on the top of the workbench 1, a clamp assembly 3 is fixedly installed on the fixed bracket 2, and the clamp assembly 3 is composed of commonly used components such as a fixed clamp plate and a fixed bolt, which belongs to the prior art, so no more explanation is given, and the fixed bracket 2 is fixedly clamped by the clamp assembly 3 to hold a hydraulic power assembly 4, and the hydraulic power assembly 4 includes components such as an oil pump, an oil tank, and a hydraulic cavity; the hydraulic cavity is fixedly clamped by the clamp assembly 3, and the oil pump and other components are placed on the workbench 1. The hydraulic power assembly 4 is an existing device, and its working method is also a well-known technical means, so no more explanation is given;

[0029] like Figure 4 , Figure 5 and Figure 6As shown, a first detection structure 7 is installed inside the fixed box 6, and the first detection structure 7 includes a fixed worm 72 rotatably connected to the upper inner wall of the fixed box 6, and a connecting rod 71 is threadedly connected to the fixed worm 72, and the connecting rod 71 passes through the upper inner wall of the fixed box 6 and is fixedly connected to a fixed plate 12, and a return spring is fixedly installed between the fixed plate 12 and the fixed box 6, and a fixed ring 10 is fixedly sleeved on the piston rod of the hydraulic power assembly 4, and the fixed ring 10 is fixedly connected to an extrusion block 11 through a connecting rod. When the hydraulic pressure of the hydraulic power assembly 4 is unstable during operation, the piston rod will shake, and the shaking of the piston rod will cause the fixing ring 10 to shake, thereby causing the connecting rod and the extrusion block 11 to shake together, and the extrusion block 11 is in contact with the fixed plate 12, and the inner wall of the fixed box 6 is rotatably connected to a worm gear shaft 74, and a fixed worm gear 73 is fixedly sleeved on the worm gear shaft 74. 73 meshes with the fixed worm 72, the inner wall of the fixed box 6 is slidably connected with a push rod 78, the push rod 78 penetrates the inner wall of the fixed box 6 and the detection frame 5 and is installed with a second detection structure 8, the push rod 78 is located at one end of the inner side of the fixed box 6 and is fixedly connected with a connecting plate 79, and a fixed spring 710 is fixedly connected to the connecting plate 79, and the fixed spring 710 is fixedly connected to the inner wall of the fixed box 6 through a first pressure sensor 711. The first pressure sensor 711 and the second pressure sensor are both existing equipment, which can convert pressure into electrical signals. When the pressure sensed by them changes, the corresponding alarm on the workbench 1 will sound an alarm. A fixed rack 75 is installed on the connecting plate 79 through a transmission component. The fixed rack 75 is a special-shaped rack, and the shape of its teeth has been specially processed so that it can mesh with the fixed worm gear 73, and the fixed rack 75 meshes with the fixed worm gear 73;

[0030] When the piston rod shakes, the extrusion block 11 will shake, thereby squeezing the fixed plate 12 to move it. When the fixed plate 12 moves downward, it will push the push rod 78 to move. Under the action of the thread, the movement of the push rod 78 will cause the fixed worm 72 to rotate. The rotation of the fixed worm 72 will cause the fixed worm gear 73 meshing with it to rotate accordingly, so that the fixed rack 75 moves. Under the action of the transmission assembly, the movement of the fixed rack 75 causes the connecting plate 79 to move. The movement of the connecting plate 79 will cause the push rod 78 to move accordingly, and at the same time, the fixed spring 710 will be deformed, causing the pressure sensed by the first pressure sensor 711 to change, so that the corresponding alarm will sound an alarm. When the piston rod shakes to other directions, the reset spring and the fixed spring 710 cooperate to reset the fixed plate 12, the push rod 78 and other structures.

[0031] like Figure 4 and Figure 7As shown, the second detection structure 8 includes a connecting shaft 87, the bottom end of the connecting shaft 87 is fixedly connected with a detection block 82, the bottom end of the detection block 82 is fixedly connected with a side plate, an oil suction plate 83 is slidably connected between the side plates, the top of the oil suction plate 83 is fixedly connected with a connecting spring 86, the connecting spring 86 is fixedly connected to the detection block 82 through a second pressure sensor, the lower inner wall of the detection frame 5 is rotatably connected with a sliding shaft 81, if there is a problem in the connection between the oil outlet pipe and the oil inlet pipe and the hydraulic cavity, hydraulic oil will flow down, and the hydraulic oil will flow into the detection frame 5, the sliding shaft 81 penetrates the oil suction plate 83 and is slidably connected with the oil suction plate 83, a connecting ratchet 84 is fixedly sleeved on the connecting shaft 87, a connecting ratchet 85 meshing with the connecting ratchet 84 is rotatably connected to the push rod 78 through a one-way bearing, and a detection auxiliary structure 9 is installed on the oil outlet pipe and the oil inlet pipe of the hydraulic power assembly 4;

[0032] As the push rod 78 moves, the connecting ratchet 85 installed on the push rod 78 moves accordingly. When the connecting ratchet 85 moves toward the first detection structure 7, the corresponding connecting ratchet 84 rotates, thereby rotating the connecting shaft 87, so that the detection block 82 and the oil absorption plate 83 connected to the detection block 82 through the side plate rotate together. If hydraulic oil drips, the oil absorption plate 83 absorbs the dripping hydraulic oil when it rotates. At this time, the mass of the oil absorption plate 83 increases, thereby stretching the connecting spring 86, and the pressure sensed by the second pressure sensor increases. The second pressure sensor controls the corresponding alarm to sound an alarm.

[0033] like Figure 8 and Fig. 9 As shown, the detection auxiliary structure 9 includes a cleaning ring 94 sleeved on the outside of the oil inlet pipe and the oil outlet pipe, the cleaning ring 94 and the oil inlet pipe and the oil outlet pipe are not connected, the inner wall of the cleaning ring 94 is fixedly connected with a cleaning scraper 97, the cleaning scraper 97 is in contact with the outer wall of the corresponding oil inlet pipe and the oil outlet pipe, and the cleaning rings 94 are connected by a belt transmission assembly 98, a mounting plate 95 is rotatably connected to the cleaning ring 94, the mounting plates 95 are fixedly connected by a mounting rod 96, a mounting rack 910 is slidably connected to the mounting plate 95 on one side, a mounting gear 99 meshing with the mounting rack 910 is fixedly sleeved on the corresponding cleaning ring 94, a mounting block 91 is fixedly connected to the push rod 78 through a telescopic rod 93, the telescopic rod 93 is an elastic structure and can be automatically extended and retracted, a pushing rod 92 is fixedly connected to the bottom end of the mounting block 91, a moving block 911 is fixedly connected to the mounting block 91 and the mounting rack 910, and a moving rod 912 is rotatably connected between the moving blocks 911;

[0034] When the push rod 78 moves back and forth, the mounting block 91 connected to it through the telescopic rod 93 moves accordingly, and the moving block 911 fixedly connected to the mounting block 91 moves back and forth together. Under the action of the moving rod 912, the other moving block 911 and the mounting rack 910 will move up and down, thereby driving the mounting plate 95 and the cleaning ring 94 to move up and down. When the cleaning ring 94 moves up and down, the cleaning scraper 97 on the inside thereof also moves up and down to scrape the flowing hydraulic oil downwards to facilitate the hydraulic oil to flow down. At the same time, when the push rod 78 moves back and forth, the oil absorption plate 83 will rotate, and the push rod 78 moves back and forth once, and the rotation amplitude of the oil absorption plate 83 is small. Therefore, when the push rod 78 moves back and forth, that is, toward the detection frame 5 When the oil absorption plate 83 moves in the opposite direction, the oil absorption plate 83 will not rotate, and the pushing rod 92 will be squeezed with the oil absorption plate 83, so that the pushing rod 92 moves in the horizontal direction. When the push rod 78 moves outward, the pushing rod 92 is separated from the oil absorption plate 83, and the installation block 91 moves back and forth with the automatic extension and retraction of the telescopic rod 93. At the same time, under the action of the moving block 911 and the moving rod 912, the installation rack 910 moves back and forth accordingly. The back and forth movement of the installation rack 910 will cause the corresponding installation gear 99 to rotate back and forth, so that the corresponding cleaning ring 94 rotates back and forth. Under the action of the belt transmission assembly 98, the other cleaning ring 94 also rotates together, and the cleaning scraper 97 rotates accordingly, thereby improving the scraping effect of the cleaning scraper 97 on the hydraulic oil.

[0035] like Figure 3 and Figure 8 As shown, a fixing rod 13 is fixedly connected to the mounting plate 95, and the fixing rod 13 is slidably connected to the fixing bracket 2. A sliding block 14 is fixedly connected to the side wall of the fixing rod 13. A sliding groove 15 matching the sliding block 14 is opened on the fixing bracket 2. An elastic member 16 is fixedly connected between the sliding block 14 and the sliding groove 15. The sliding block 14, the sliding groove 15 and the elastic member 16 cooperate to facilitate the upward and downward movement of the fixing rod 13 and the mounting plate 95; as shown in FIG. Fig. 9 As shown, the cleaning scraper 97 is arc-shaped, and a chamfer is formed on the cleaning scraper 97, so that the cleaning scraper 97 can scrape off the hydraulic oil, and the arc-shaped cleaning scraper 97 is also conducive to the scraped hydraulic oil flowing downward when the cleaning scraper 97 rotates;

[0036] like Figure 5 As shown, the transmission assembly includes an adjusting rod 77, an adjusting block is slidably connected to the adjusting rod 77, an adjusting shaft is rotatably connected to the adjusting block, the adjusting shaft is fixedly connected to the inner wall of the fixed box 6, and the adjusting shaft acts as a fulcrum. When one end of the adjusting rod 77 moves, the other end of the adjusting rod 77 will move in the opposite direction with the adjusting shaft as the fulcrum. The two ends of the adjusting rod 77 are rotatably connected to fixed blocks 76. The fixed block 76 on one side is fixedly connected to the fixed rack 75, and the fixed block 76 on the other side is slidably connected to the connecting plate 79, as shown in FIG. Figure 5As shown, when the fixed rack 75 moves downward, the corresponding fixed block 76 moves downward accordingly, thereby pulling the adjustment rod 77 at this end to move, and the other end of the adjustment rod 77 moves to the right;

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the detection frame 5 is divided into two parts, and the positions of the two parts match the oil inlet pipe and the oil outlet pipe respectively, so that the hydraulic oil flowing from the oil outlet pipe and the oil inlet pipe flows to different positions in the detection frame 5, so that the specific position of the hydraulic leakage can be detected.

[0038] In the present invention, when the device is in use, the oil pump is started and the running state of the oil pump is adjusted to make the piston rod move back and forth. During the movement of the piston rod, if the piston rod shakes, the extrusion block 11 will shake, thereby squeezing the fixed plate 12 to make it move. When the fixed plate 12 moves downward, it will push the push rod 78 to move. Under the action of the thread, the movement of the push rod 78 will cause the fixed worm 72 to rotate. The rotation of the fixed worm 72 will cause the fixed worm wheel 73 meshing with it to rotate accordingly, so that the fixed rack 75 moves. Under the action of the transmission assembly, the fixed rack 75 The movement makes the connecting plate 79 move, and the movement of the connecting plate 79 makes the push rod 78 move accordingly. At the same time, the transmission assembly and the push rod 78 and other structures can amplify the displacement caused by the shaking of the piston rod, making it more intuitive, and can cause the fixed spring 710 to deform, so that the pressure sensed by the first pressure sensor 711 changes, so that the corresponding alarm alarms. When the piston rod shakes to other directions, the reset spring and the fixed spring 710 cooperate to reset the fixed plate 12, the push rod 78 and other structures to determine whether the hydraulic pressure of the hydraulic power assembly 4 is stable;

[0039] At the same time, as the push rod 78 moves, the connecting ratchet 85 installed on the push rod 78 moves accordingly. When the connecting ratchet 85 moves toward the first detection structure 7, the corresponding connecting ratchet 84 will rotate, thereby rotating the connecting shaft 87, so that the detection block 82 and the oil absorption plate 83 connected to the detection block 82 through the side plate rotate together. If hydraulic oil drips, the oil absorption plate 83 will absorb the dripping hydraulic oil when it rotates. At this time, the mass of the oil absorption plate 83 increases, thereby stretching the connecting spring 86, and the pressure sensed by the second pressure sensor increases. The second pressure sensor controls the corresponding alarm to alarm, thereby judging whether there is a problem with the pipeline setting of the hydraulic oil pipe or whether the hydraulic oil leaks and causes hydraulic instability;

[0040] Moreover, when the push rod 78 moves back and forth, the mounting block 91 connected thereto through the telescopic rod 93 moves accordingly, and the moving block 911 fixedly connected to the mounting block 91 moves back and forth together. Under the action of the moving rod 912, the other moving block 911 and the mounting rack 910 move up and down, thereby driving the mounting plate 95 and the cleaning ring 94 to move up and down. When the cleaning ring 94 moves up and down, the cleaning scraper 97 inside it also moves up and down to scrape the flowing hydraulic oil downwards, so as to facilitate the hydraulic oil to flow down. Figure 8 As shown, taking the push rod 78 as a reference, when the push rod 78 moves to the left, that is, moves toward the direction close to the fixed box 6, the oil absorption plate 83 will rotate, and the mounting block 91, the telescopic rod 93 and the pushing rod 92 will also move to the left, and the pushing rod 92 will be away from the oil absorption plate 83. When the push rod 78 moves to the right, the oil absorption plate 83 stops, and the telescopic rod 93, the mounting block 91 and the pushing rod 92 move to the right, and the pushing rod 92 will be squeezed with the side wall of the oil absorption plate 83, so that the pushing rod 92 moves in the direction away from the push rod 78. Then, when the push rod 78 moves to the left again, the pushing rod 92 moves to the left again and separates from the oil absorption plate 83, and the automatic extension of the telescopic rod 93 is cooperated. The mounting block 91 shrinks and moves back and forth until the oil absorption plate 83 rotates to the point that the back and forth movement of the pushing rod 92 can no longer produce extrusion therewith. At this time, the pushing rod 92 and the mounting block 91 no longer move back and forth. At the same time, under the action of the moving block 911 and the moving rod 912, the mounting rack 910 moves back and forth accordingly. The back and forth movement of the mounting rack 910 causes the corresponding mounting gear 99 to rotate back and forth, allowing the corresponding cleaning ring 94 to rotate back and forth. Under the action of the belt drive assembly 98, the other cleaning ring 94 also rotates together, and the cleaning scraper 97 rotates accordingly, thereby improving the scraping effect of the cleaning scraper 97 on the hydraulic oil, allowing the hydraulic oil to flow down quickly, so as to facilitate its detection, thereby shortening the time required for detection.
