[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example 1 like Figure 1-4 As shown, the present invention provides a testing device for industrial control equipment, including a test bench 1, which has two symmetrical guide grooves 14 on it, and a movable platform 2 is movably provided on the surface of the guide grooves 14, and a clamping plate 3 is provided on the surface of the movable platform 2. A hydraulic pump 18 is installed at the bottom of the test bench 1, and the output shaft of the hydraulic pump 18 is fixedly connected to a lifting push plate 17. Both sides of the lifting push plate 17 are rotatably connected to a retraction push rod 16, and the end of the retraction push rod 16 away from the lifting push plate 17 is rotatably connected to a guide push plate 15, and the end of the guide push plate 15 away from the lifting push plate 17 is respectively connected to the bottom of the movable platform 2, and a limiting plate groove 9 is respectively provided on the side away from each other of the two clamping plates 3, and a movable limiting plate 7 is respectively slidably provided in the limiting plate groove 9, and the bottom of the movable limiting plate 7 is fixedly connected to a limiting rod 13, and the limiting rod 13 is arranged through the clamping plate 3, and a lifting platform 5 is installed in the middle of the surface of the test bench 1.

[0029] As an embodiment of the present invention, adapter grooves are respectively provided on both sides of the lifting push plate 17, one end of the guide push plate 15 is rotatably connected to the adapter groove, and the other end of the guide push plate 15 passes through the guide groove 14 through a rotating shaft and is rotatably connected to the bottom of the movable platform 2. The present invention provides adapter grooves on both sides of the lifting push plate 17 and rotatably connects one end of the guide push plate 15 to these adapter grooves. This design ensures a stable connection between the lifting push plate and the guide push plate. This connection method can prevent the lifting push plate from offsetting or shaking during the lifting process, thereby improving the stability of the entire structure. The other end of the guide push plate 15 passes through the guide groove 14 through a rotating shaft and is rotatably connected to the bottom of the movable platform 2. This design allows the guide push plate to rotate within a certain range. This flexibility not only helps to adapt to different work scenarios and lifting requirements, but also reduces friction and wear caused by mechanical movement.

[0030] As an embodiment of the present invention, the surface of the movable platform 2 is respectively provided with an adjustment inner groove 4, one end of the clamping plate 3 is slidably connected in the adjustment inner groove 4, and a plurality of limiting holes 11 are provided on the movable platform 2, the limiting holes 11 are arranged along the length direction of the adjustment inner groove 4, and the limiting holes 11 are connected to the adjustment inner groove 4. The adjustment inner groove 4 provided on the surface of the movable platform 2 allows one end of the clamping plate 3 to slide inside it. This design provides great flexibility, so that the position of the clamping plate 3 can be precisely adjusted according to actual needs. By providing a plurality of limiting holes 11 on the movable platform 2 and arranging these limiting holes in the length direction of the adjustment inner groove 4, it can be ensured that the clamping plate 3 can be stably fixed after being adjusted into place. The limiting holes 11 are connected to the adjustment inner groove 4, which means that some kind of locking mechanism (such as bolts, pins, etc.) can be used to pass through the limiting holes 11 to fix the position of the clamping plate 3 to prevent it from moving during operation.

[0031] As an embodiment of the present invention, two mutually symmetrical through holes 10 are provided at the bottom of the clamping plate 3, and one end of the limiting rod 13 is movable through the through hole 10 and inserted into the limiting hole 11 of the movable platform 2. Through the combination of the through hole 10 and the limiting rod 13, a flexible and stable connection is established between the clamping plate 3 and the movable platform 2. This design allows the clamping plate 3 to be adjusted or moved as needed while maintaining a certain position stability. One end of the limiting rod 13 is movable through the through hole 10 and inserted into the limiting hole 11 of the movable platform 2. This structure effectively limits the movement of the clamping plate 3 in the horizontal direction, thereby enhancing the stability of the entire device. The design of the through hole 10 and the limiting rod 13 makes the connection between the clamping plate 3 and the movable platform 2 simple and quick.

[0032] As an embodiment of the present invention, the two ends of the movable limit plate 7 are respectively slidably connected to the inner walls on both sides of the limit plate groove 9, and the top of the movable limit plate 7 is connected to the top of the limit plate groove 9 by a plurality of restoration springs 8. The sliding connection design ensures that the movable limit plate 7 can move smoothly and smoothly in the limit plate groove 9, and is not prone to jamming or offset, thereby improving the stability and reliability of the entire structure. The setting of the restoration spring 8 plays an important role in buffering and shock absorption. When the movable limit plate 7 is subjected to external force, the restoration spring 8 can absorb and disperse the impact force, protect other components from damage, and enable the movable limit plate 7 to quickly return to its original position. Due to the elastic action of the restoration spring 8, the movable limit plate 7 can automatically return to its initial position after being deviated from its original position by external force. This self-resetting ability simplifies structural control, reduces maintenance costs, and improves operating efficiency.

[0033] As an embodiment of the present invention, a plurality of guide rails 6 are installed on the surface of the test bench 1, and track grooves 12 are respectively provided at both ends of the bottom of the mobile platform 2. The guide rails 6 and the track grooves 12 are arranged in a one-to-one correspondence, and the track grooves 12 are respectively slidably connected to the guide rails 6. The sliding connection between the guide rails 6 and the track grooves 12 ensures the smooth movement of the mobile platform 2 on the surface of the test bench 1. This design reduces the bumps and vibrations during the movement, so that the mobile platform 2 can maintain a stable motion trajectory. The one-to-one correspondence between the guide rails 6 and the track grooves 12 provides a precise guiding effect. This design ensures that the mobile platform 2 will not deviate from the predetermined path during the movement, thereby improving the accuracy and reliability of the test. Through the sliding connection between the guide rails 6 and the track grooves 12, a stable structural system is formed between the test bench 1 and the mobile platform 2. This design enhances the stability of the entire device and reduces the risk of structural deformation or damage caused by movement.

[0034] As an embodiment of the present invention, a hydraulic pump 18 is installed in the middle position of the bottom of the test bench 1, and a plurality of guide rods 19 are installed at the bottom of the test bench 1. The guide rods 19 are movable through the outer side of the lifting push plate 17, and a protruding block is provided at one end of the guide rod 19 that passes through the lifting push plate 17.

[0035] Example 2 The present invention provides a method for using a testing device for industrial control equipment, comprising the following steps: Step 1: Place the industrial control equipment to be tested on the surface of the elevated platform 5, between the two movable platforms 2; Step 2: Adjust the position of the clamping plate 3 on the movable platform 2 again. Slide the clamping plate 3 to raise the position of the limit rod 13, push the clamping plate 3, bring the clamping plate 3 close to the industrial control device, and move it to both sides of the industrial control device. Step 3: Start the hydraulic pump 18, which pushes the lifting push plate 17, which moves downward, and retracts the push rod 16 to pull the two moving platforms 2 closer to each other, and fix the industrial control equipment and test the industrial control equipment.

[0036] Use the two clamping plates 3 to make adjustments, pull the clamping plates 3, and after the limiting rod 13 is away from the limiting hole 11, the position of the clamping plates 3 can be freely slid, and the clamping plates 3 are moved to both sides of the industrial control equipment, so that the clamping distance of the hydraulic pump 18 is shortened, and the hydraulic pump 18 does not need to move over a large range. In the natural state, the recovery spring 8 supports the mobile limiting plate 7 in the clamping plate 3, so that the limiting rod 13 is always inserted into the limiting hole 11, locking the position of the clamping plate 3; When the movable platform 2 is clamped, it is pushed by the hydraulic pump 18 to move on the surface of the test bench 1. The movable platform 2 slides along the guide rail 6, and the guide rail 6 defines the direction and path of movement. When the hydraulic pump 18 moves downward, the retracted push rod 16 pulls the guide push plates 15 on both sides closer together, thereby clamping them. When the hydraulic pump 18 moves upward, the retracted push rod 16 pushes the guide push plates 15 on both sides away from each other, thereby separating the two clamping plates 3.

[0037] In summary, the present invention can adapt to industrial control equipment of different sizes by adjusting its position on the mobile platform through a sliding clamping plate. This flexibility ensures that the test device can be widely used for equipment of various sizes and shapes. The design of the limit rod and limit hole allows the clamping plate to be fixed in position when needed and to move freely when not needed, which increases the convenience of operation. The hydraulic pump pushes the lifting push plate downward, and the two mobile platforms are pulled closer together by retracting the push rod, achieving rapid fixation of the industrial control equipment. This design improves testing efficiency. The guide rail not only defines the movement direction and path of the mobile platform, but also increases its stability during movement, preventing testing errors caused by shaking or offset. The design of the clamping plate can firmly clamp the industrial control equipment, preventing it from moving or falling during the test process, thereby ensuring the safety of the test. The use of components such as the hydraulic pump and the retracting push rod are proven and reliable technologies that can ensure the stability and reliability of the test device during long-term use. The present invention adapts to equipment of different sizes by adjusting the position of the clamping plate, avoiding the need to customize a dedicated test fixture for each device, thereby reducing testing costs. The structure of the test device is compact and efficient, which can fully utilize the test space and improve the utilization rate of test resources.
