[0006] In order to achieve the above object, the utility model provides the following technical scheme: A deformation detection device for high -speed rail maintenance, including detection box body, the lower end of left and right sides of detection box body all is provided with guide wheel, the right side of detection box body top installs alarm lamp, the middle position of detection box body top installs servo motor, the lower end of detection box body inside is provided with detection probe, and the output of servo motor extends to the inside of detection probe and is provided with adjusting mechanism for adjusting detection probe height, adjusting mechanism includes threaded rod, and the threaded rod sets up in the output of servo motor, the outside of threaded rod is installed with support rod through movable block, and the bottom of support rod is connected with the top of detection probe, the upper end of left and right sides in detection box body inside all is provided with pressing plate, and the side of pressing plate is provided with dust removal mechanism for dust removal of detection probe.
[0007] Further, the threaded rod and the movable block are threadedly connected, and the support rod is arranged on the left and right sides of the movable block.
[0008] Further, the output of the servo motor is provided with a driving gear, the front and rear ends of the driving gear are engaged with a rack, and the bottom end of the rack is connected with a shielding plate through a connecting rod.
[0009] Further, the bottom end of the detection box body is provided with a first sliding groove, and the inside of the first sliding groove is provided with a matching first sliding block, the bottom end of the detection box body is provided with a second sliding groove, and the inside of the second sliding groove is provided with a matching second sliding block, and the top end of the first sliding block and the second sliding block is connected with the connecting rod.
[0010] Further, the bottom end of the connecting rod passes through the first sliding groove through the first sliding block and is connected with the shielding plate, and the bottom end of the connecting rod is connected with the detection box body through the second sliding block to form a sliding connection.
[0011] Further, the dust removal mechanism includes an elastic air bag, and the elastic air bag is arranged on the side of the pressing plate, the bottom end of the elastic air bag is provided with a jet nozzle through a hose, and the jet nozzle is arranged on the left and right sides of the detection probe.
[0012] Further, the front and rear ends of the side of the pressing plate are provided with return springs, and the pressing plate and the detection box body are connected through the return springs to form an elastic structure.
[0013] Compared with the prior art, the utility model has the advantages that:
[0014] 1. The output end of the servo motor rotates and drives the threaded rod to rotate. During the rotation of the threaded rod, the movable block connected by the external thread moves up and down, and drives the support rod to move up and down. As a result, the detection probe at the bottom of the support rod is pushed out of the bottom of the detection box body along the fixed groove. The detection probe can be used to detect the rail below, so as to better detect the rail below and ensure the safety of the rail during subsequent use.
[0015] Furthermore, the first slider passes through the first groove and connects with the baffle plate, while the second slider slides inside the second groove and supports the left side of the rack. This causes the rack to move synchronously when the servo motor rotates. The bottom end of the rack moves the baffle plate to both sides through the connecting rod, and the baffle plate stops blocking the fixing groove at the bottom of the detection box body. This allows the detection probe to be exposed to the outside world and to detect the track. The baffle plate can protect the detection probe, thereby improving the safety of the detection probe when it is not in use.
[0016] Furthermore, the first slide groove and the second slide groove are respectively set on both sides of the bottom end of the detection box body. At the same time, the first slide groove and the second slide groove have different depths. The first slide groove runs through the bottom end of the detection box body, thereby enabling the first slider to connect the shield and control the shield to move left and right, increasing the applicability during use.
[0017] 2. The meshing between the drive gear and the rack allows the edge of the rack to press against the pressing plate, which in turn presses the elastic airbag. The gas inside the elastic airbag is output through a hose and then through a nozzle to blow air onto the bottom of the detection probe, keeping the probe clean and preventing data deviation caused by dust during use.
[0018] Furthermore, the reset springs at both ends of the pressing plate can assist the pressing plate in quickly resetting when it is not being squeezed, thereby enabling the elastic airbag to reset and inflate when it is not being squeezed, allowing the elastic airbag to be repeatedly squeezed and cleaning the dust from the detection probe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: As Figures 1-6 The technical solution presented addresses the problem that traditional deformation detection devices are inconvenient to store and protect the detection probe during use, leading to reduced applicability and impacting the safety of high-speed rail operations. This high-speed rail maintenance deformation detection device discloses an adjustment mechanism, including a detection box body 1. Guide wheels 2 are installed at the lower ends of both sides of the detection box body 1, and an alarm light 3 is installed on the right side of the top of the detection box body 1. A servo motor 4 is installed at the middle of the top of the detection box body 1. A detection probe 7 is located at the lower end inside the detection box body 1, and the output end of the servo motor 4 extends into the interior of the detection probe 7, where an adjustment mechanism for adjusting the height of the detection probe 7 is provided. The adjustment mechanism includes a threaded rod 5, which is located at the output end of the servo motor 4. A support rod 8 is installed on the outer side of the threaded rod 5 via a movable block 6, and the bottom end of the support rod 8 is connected to the top of the detection probe 7. The threaded rod 5 and the movable block 6 are threadedly connected, and the support rod 8 is located on the left and right sides of the movable block 6.
[0028] In this example, the output of the servo motor 4 rotates, driving the threaded rod 5 to rotate. During the rotation of the threaded rod 5, the movable block 6 connected by the external thread moves up and down, driving the support rod 8 to move up and down. This causes the detection probe 7 at the bottom of the support rod 8 to be pushed out of the bottom of the detection box body 1 along the fixed groove. The detection probe 7 can be used to detect the rails below, and to detect the distance and gauge between the two rails, ensuring that the spacing between the rails meets the internationally accepted standard gauge. The height deviation of the rail surface and the directional deviation of straight and curved sections need to be controlled within the specified range. The detection probe 7 can detect these data, thereby ensuring the safety of the high-speed rail track during subsequent use.
[0029] Example 2: Figures 1-5 The technical solution shown addresses the problem that the lower end of the detection probe 7 remains exposed after being stored inside the detection box body 1, making it susceptible to damage from flying debris during the movement of the detection box body 1. This high-speed rail maintenance deformation detection device discloses a protective mechanism: a drive gear 9 is installed at the output end of the servo motor 4, and racks 10 mesh at both ends of the drive gear 9.

The top ends of both the first slider 12 and the second slider 16 are connected to the connecting rod 11. The bottom end of the connecting rod 11 passes through the first sliding groove 13 via the first slider 12 and is connected to the baffle plate 14. The bottom end of the connecting rod 11 is slidably connected to the detection box body 1 via the second slider 16.
[0030] In this case, the output end of the servo motor 4 can drive the driving gear 9 to rotate when rotating, and the driving gear 9 is in meshing with the rack 10 when rotating, so that the rack 10 can drive the connecting rod 11 at the lower end to move, and the first sliding block 12 and the second sliding block 16 are arranged at the bottom of the connecting rod 11, the first sliding block 12 passes through the first sliding groove 13 and is connected with the shielding plate 14, and the second sliding block 16 slides in the second sliding groove 15 and supports the left side of the rack 10, so that the rack 10 is synchronously driven to move when the servo motor 4 rotates, and the bottom of the rack 10 drives the shielding plate 14 to move to both sides through the connecting rod 11, and the shielding plate 14 stops shielding the fixed groove at the bottom of the detection box body 1, so that the detection probe 7 can be exposed to the outside and detect the track; the first sliding groove 13 and the second sliding groove 15 are arranged on both sides of the bottom of the detection box body 1, and the depths of the first sliding groove 13 and the second sliding groove 15 are different, the first sliding groove 13 penetrates the bottom of the detection box body 1, so that the first sliding block 12 can connect the shielding plate 14 and control the shielding plate 14 to move left and right, increasing the applicability during use.
[0031] Embodiment three: as shown in the technical scheme of Figure 1 、 Figure 2 and Figure 5 , in order to solve the problem that the surface of the detection probe 7 is left with dust during use, affecting the detection accuracy: the deformation detection device for high-speed rail maintenance discloses a dust removal mechanism, the upper end of the left and right sides in the detection box body 1 is provided with a pressing plate 17, and the side of the pressing plate 17 is provided with a dust removal mechanism for removing dust from the detection probe 7; the front and rear ends of the side of the pressing plate 17 are provided with a reset spring 19, and the pressing plate 17 and the detection box body 1 constitute an elastic structure through the reset spring 19.
[0032] In this case, the output end of the servo motor 4 drives the driving gear 9 to rotate, the driving gear 9 is in meshing with the rack 10, so that the side of the rack 10 can extrude the pressing plate 17, so that the pressing plate 17 can press the elastic air bag 18, the gas in the elastic air bag 18 is output through the hose, then the gas is output to the outside through the air jet nozzle 20, and the bottom of the detection probe 7 is blown, so that the probe at the bottom of the detection probe 7 can keep clean, avoiding the case that the detection data is deviated due to dust when the detection probe 7 is used; the reset spring 19 arranged at the front and rear ends of the pressing plate 17 can assist the pressing plate 17 to reset quickly when it is not extruded, so that the elastic air bag 18 can reset and inflate when it is not extruded, so that the elastic air bag 18 can be extruded repeatedly and clean the dust of the detection probe 7.
[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
