Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of high labor intensity and poor data accuracy caused by the need for manual pressing, which brings the pressure sensor 400 into contact with the deceleration top 200, this invention provides a deceleration top condition detection device. This device utilizes a moving component 300 to move the pressure sensor 400 relative to the rail 100 along its length to position the deceleration top 200 on the rail 100. Simultaneously, driven by a driving component 500, the pressure sensor 400 can move closer to or further away from the deceleration top 200, allowing it to come into contact with the deceleration top 200 and test its condition.

[0021] Please see Figures 1 to 4 , Figure 1 , Figure 2 This is a schematic diagram of a deceleration top condition detection device according to an embodiment of the present invention. The deceleration top condition detection device is configured to connect two parallel and spaced-apart steel rails 100. Multiple deceleration tops 200 are spaced apart along the length of the steel rails 100. The deceleration top condition detection device includes: a moving component 300, a pressure sensor 400, and a driving component 500. The moving component 300 is connected to both steel rails 100 and can move relative to the steel rails 100 along the guide of the steel rails 100. The pressure sensor 400 is connected to the moving component 300 and can move towards or away from the steel rails 100. The driving component 500 has a fixed end and a movable end. The fixed end of the driving component 500 is connected to the moving component 300, and the movable end is connected to the pressure sensor 400, for driving the pressure sensor 400 to abut against or disengage from the deceleration tops 200.

[0022] In this device, compared with the prior art, the moving component 300 drives the pressure sensor 400 to move relative to the rail 100 along the length of the rail 100 to position the deceleration top 200 on the rail 100. At the same time, driven by the driving component 500, the pressure sensor 400 can move closer to or further away from the deceleration top 200, so that the pressure sensor 400 can come into contact with the deceleration top 200 and test the working condition of the deceleration top 200. This solves the technical problem in the prior art that the pressure sensor 400 needs to be manually pressed down to make it come into contact with the deceleration top 200, resulting in high labor intensity for the testing personnel and poor accuracy of the test data.

[0023] Furthermore, the deceleration top working condition detection device also includes at least one rail gripping mechanism 700. The rail gripping mechanism 700 has two mutually hinged claws, which can close or open to grip the rail 100. The rail gripping mechanism 700 is a conventional setting known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN214224507U, entitled "A Manual Deceleration Top 200 Detection Trolley". It will not be described in detail here.

[0024] Furthermore, in some embodiments, such as Figures 1 to 3 As shown, the deceleration top working condition detection device has two rail gripping mechanisms 700. The two rail gripping mechanisms 700 are evenly arranged on both sides of the pressure sensor 400 to form a stable rail gripping structure, which will not be described in detail here.

[0025] Furthermore, in some embodiments, such as Figure 4 As shown, the deceleration top working condition detection device also includes a distance sensor 600. The distance sensor 600 can detect the distance parameter after the deceleration top 200 is pressed down. The distance sensor 600 is a common and readily available device on the market and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0026] Furthermore, the pressure sensor 400 here is a common and readily available device on the market. The detection end of the pressure sensor 400 is connected to the deceleration top 200 via a pressure block to detect the pressure value acting on the deceleration top 200. The distance sensor 600 is used to detect the distance parameter after the deceleration top 200 is pressed down. Users can compare the pressure value and distance parameter with the working condition change curve of the deceleration top 200 to help determine whether the deceleration top 200 is working properly. This is a conventional setting known to those skilled in the art. For reference, please refer to the Chinese utility model patent with publication number CN214224507U, entitled "A Manual Deceleration Top 200 Detection Trolley". Further details are omitted here.

[0027] In this embodiment, as Figure 2 , Figure 3As shown, the moving component 300 includes a movable support 310, at least one first roller 320, and at least one first drive member 330. The movable support 310 is disposed on a rail 100 and is configured to connect to the pressure sensor 400. The first roller 320 is connected to the movable support 310 and is capable of rolling relative to the rail 100. The first drive member 330 is connected to the movable support 310 and the first roller 320 and is used to drive the movable support 310 and the pressure sensor 400 to move relative to the rail 100.

[0028] By using the first driving component 330 to drive the first roller 320 to roll relative to the rail 100, the movable bracket 310 and the pressure sensor 400 can be moved relative to the rail 100.

[0029] Furthermore, the first roller 320 here is a common and readily available wheelset structure on the market, which can achieve guided rolling along the rail 100. The first drive component 330 here includes two synchronous pulleys, a synchronous belt and a stepper motor. The two synchronous pulleys are respectively fixedly sleeved on the first roller 320 and the output shaft of the stepper motor, and the synchronous belt meshes with the two synchronous pulleys. The output shaft of the stepper motor can realize the drive control of the first roller 320.

[0030] Furthermore, in some embodiments, such as Figure 2 As shown, there are two first rollers 320 and two first driving members 330. The two first rollers 320 are distributed on both sides of the movable bracket 310 to form a stable support structure. Under the drive of the two first driving members 330, the two first rollers 320 can roll relative to the rail 100 respectively.

[0031] In this embodiment, as Figure 3 As shown, the drive assembly 500 includes at least one guide rod 510, a lifting platform 520, and a second drive component 530. The second drive component 530 includes a fixed base 531, a screw 532, and a drive motor 533. The second drive component 530 also includes a first synchronous pulley 534, a second synchronous pulley 535, and a first synchronous belt 536. The drive assembly 500 also includes a housing 540. The moving assembly 300 also includes two position sensors 340, a proximity switch 350, at least one second roller 360, a connecting rod 370, and at least one bolt 380.

[0032] The second roller 360 is mounted on another rail 100 and can roll relative to the other rail 100. One end of the connecting rod 370 is connected to the second roller 360 and the other end is detachably connected to the housing 540.

[0033] At least one second roller 360 forms a stable support structure with the movable bracket 310 and the first roller 320 via a connecting rod 370, and is able to travel along two parallel and spaced-apart rails 100.

[0034] Furthermore, the connecting rod 370 is detachably connected to the movable bracket 310, which facilitates the user's disassembly and assembly of the deceleration top condition detection device, thereby making it convenient for the user to install the deceleration top condition detection device on the rail 100 or remove it from the rail 100.

[0035] In one embodiment, please refer to Figure 3 The housing 540 has a slot and at least one second threaded hole communicating with the slot. The side wall of the connecting rod 370 has a fixing groove along its guide. The other end of the connecting rod 370 is inserted into the slot. The moving assembly 300 also includes a bolt 380. The threaded section of the bolt 380 is threadedly connected to the second threaded hole and abuts against the inner wall of the fixing groove.

[0036] The connecting rod 370 is fixed to the slot by inserting it into the slot and using the detachable connection between the bolt 380 and the threaded hole. This not only makes the structure simple but also makes the operation convenient.

[0037] Furthermore, the two opposite side walls of the slot are provided with second threaded holes, and two bolts 380 are threaded into the second threaded holes respectively, and abut against the fixing groove on one end of the connecting rod 370 to limit the sliding of the connecting rod 370 relative to the slot.

[0038] In one embodiment, please refer to Figure 4 Two position sensors 340 are respectively disposed on both sides of the pressure sensor 400 and are both connected to the housing 540, and both position sensors 340 are electrically connected to the first drive component 330.

[0039] By using two position sensors 340 to detect the deceleration top 200, the automatic positioning of the deceleration top 200 can be improved.

[0040] Furthermore, when both position sensors 340 detect the deceleration top 200, it proves that the deceleration top 200 is located directly below the pressure sensor 400. The position sensor 340 is a common and readily available device on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0041] In one embodiment, please refer to Figure 4 The inductive switch 350 is disposed on one side of a position sensor 340 and connected to the housing 540, and the inductive switch 350 is electrically connected to the first driving member 330.

[0042] The inductive switch 350 is used in conjunction with two position sensors 340 to improve the accuracy of the deceleration top 200's position positioning.

[0043] Furthermore, the inductive switch 350 here is a common and readily available inductive inductive switch 350 on the market. The inductive inductive switch 350 can determine whether the object located between the two position sensors 340 is metal, thereby avoiding the interference of weeds next to the rail 100 on the working condition detection and improving the efficiency of retrieval.

[0044] In some embodiments, the inductive switch 350 and the two position sensors 340 are electrically connected to the two stepper motors, and a PLC controller is used to realize automated control. That is, when the inductive switch 350 and the two position sensors 340 detect the deceleration top 200, the inductive switch 350 and the two position sensors 340 send electrical signals to the PLC controller, and the PLC controller issues a command to control the stepper motor to stop driving the first roller 320 to roll.

[0045] Furthermore, the PLC controller is electrically connected to the rail gripping mechanism 700. When the first roller 320 stops rolling and receives a release signal, the PLC controller can control the rail gripping mechanism 700 to grip the rail 100, thereby improving the accuracy of detection. The control logic of the PLC controller here is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0046] In one embodiment, please refer to Figure 3 The guide rod 510 is connected to the movable bracket 310. The lifting platform 520 is slidably sleeved on the guide rod 510 and connected to the pressure sensor 400. The second drive component 530 is connected to the movable bracket 310 and the lifting platform 520, and is used to drive the lifting platform 520 and the pressure sensor 400 to rise and fall relative to the movable bracket 310 along the guide rod 510.

[0047] The guide rod 510 cooperates with the lifting platform 520 to connect and guide the lifting of the lifting platform 520 relative to the movable support 310. The second drive component 530 drives the lifting of the lifting platform 520.

[0048] Furthermore, the movable bracket 310 has a through slot, the movable plate is connected to the lifting platform 520 and is movably inserted into the through slot, and the pressure sensor 400 and the distance sensor 600 are connected to the lifting platform 520 through the movable plate. The cooperation structure between the movable plate and the through slot is used to improve the stability of the lifting process.

[0049] In one embodiment, please refer to Figure 3The lifting platform 520 has a through hole, the fixed seat 531 is connected to the lifting platform 520, and a first threaded hole is opened opposite the through hole. One end of the screw 532 passes through the through hole and the first threaded hole in sequence, and is rotatably connected to the movable bracket 310. The fixed end of the drive motor 533 is connected to the movable bracket 310, and the output shaft is connected to the other end of the screw 532, which is used to drive the lifting platform 520 to rise and fall relative to the movable bracket 310.

[0050] The fixed base 531, screw 532 and drive motor 533 form a linear drive structure similar to a ball screw and nut pair. The output shaft of drive motor 533 rotates relative to its fixed end, which can drive the lifting platform 520 to rise and fall relative to the movable bracket 310, thereby realizing the movement of pressure sensor 400 and distance sensor 600 relative to deceleration top 200.

[0051] Furthermore, the screw 532 here is rotatably connected to the movable bracket 310 via a rotary bearing, which will not be described in detail here.

[0052] In one embodiment, please refer to Figure 3 The first synchronous pulley 534 is fixedly sleeved on the screw 532, and the second synchronous pulley 535 is fixedly sleeved on the output shaft of the drive motor 533. The first synchronous belt 536 meshes with both the first synchronous pulley 534 and the second synchronous pulley 535.

[0053] The transmission structure consisting of the first synchronous pulley 534, the second synchronous pulley 535, and the first synchronous belt 536 enables the transmission of motion and allows for a reasonable distribution of structural space and installation position.

[0054] In one embodiment, please refer to Figure 3 The housing 540 is covered by the fixed base 531, screw 532, drive motor 533, first synchronous pulley 534, second synchronous pulley 535 and first synchronous belt 536, and is connected to the movable bracket 310.

[0055] The housing 540 structure protects the fixed base 531, screw 532, drive motor 533, first synchronous pulley 534, second synchronous pulley 535 and first synchronous belt 536, thereby improving the stability of the device during operation.

[0056] In some embodiments, the connecting rod 370 is also provided with a storage tray for placing items, and a power supply that is electrically connected to the drive motor 533, stepper motor, rail gripping mechanism 700, pressure sensor 400 and distance sensor 600, position sensor 340 and inductive switch 350. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: A pressure sensor 400 is mounted on a moving component 300. Driven by the moving component 300, the pressure sensor 400 moves along the guide rail 100. The pressure sensor 400 is connected to the moving component 300 via a driving component 500. The fixed end of the driving component 500 is connected to the moving component 300, and the movable end is connected to the pressure sensor 400. This drives the pressure sensor 400 to move closer to or away from the deceleration top 200, and to come into contact with the deceleration top 200, thus detecting the operating condition of the deceleration top 200. Compared to existing technologies, the moving component 300 moves the pressure sensor 400 relative to the rail 100 along the length of the rail 100 to position the deceleration top 200 on the rail 100. Simultaneously, driven by the driving component 500, the pressure sensor 400 can move closer to or away from the deceleration top 200, allowing it to come into contact with the deceleration top 200 and test its operating condition.

[0058] In the specific working process of this utility model, during use, the user first installs the first roller 320 on one rail 100 and the second roller 360 on another rail 100, and the overall structure is installed through the connecting rod 370. Then, driven by the stepper motor, the first roller 320 and the second roller 360 enable the detection device to move along the length direction of the rail 100. Then, when both position sensors 340 and the inductive switch 350 detect the deceleration top 200, the stepper motor stops driving the first roller 320, and the detection device stops moving. The pressure sensor 400 is positioned above the deceleration top 200 after fine-tuning. Finally, the rail-grabbing mechanism 700 grips the rail 100, and the lifting platform 520 descends under the drive of the drive motor 533. This causes the detection end of the pressure sensor 400 to contact the deceleration top 200 and press down on it. During the pressing process, the pressure sensor 400 and the distance sensor 600 continuously collect and provide feedback on the pressure and distance parameters to assist the inspection personnel in judging the working condition of the deceleration top 200.

[0059] Furthermore, after a measurement is completed, the lifting platform 520 causes the pressure sensor 400 to separate from the deceleration top 200, and the stepper motor continues to drive the first roller 320, so that the detection device moves above the next detection object, and so on.

[0060] This application, through the above structure, can solve the technical problem in the prior art where the pressure sensor 400 needs to be manually pressed down to make contact with the deceleration top 200, resulting in high labor intensity for testing personnel and poor accuracy of testing data.

[0061] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
