Description

Technical Field

[0001] The utility model relates to the technical field of track detection, in particular to a track detection and maintenance device. Background Art

[0002] Railway tracks are usually composed of two parallel rails, which are fixed on sleepers so that trains can run without turning. After a period of use, the railway tracks need to be inspected. Inspection of the flatness of the rails is an important part of ensuring track quality and improving driving safety.

[0003] After checking the public (announcement) number: CN218141510U, a track detection device for railway engineering maintenance is disclosed. This technology discloses "a track detection device for railway engineering maintenance, including a platform, a bearing seat and a through slot are arranged on the platform, the bearing seat is symmetrically fixed to the middle two ends of the top of the platform by screws, a bidirectional screw is connected to the bearing seat through a bearing interference fit, the middle section of the bidirectional screw is integrally formed and connected with a hexagonal column, and the through slot is symmetrically opened on both sides of the top of the platform" and other technical solutions, which have "the flatness of the railway track can be easily detected, effectively improving the detection efficiency" and other technical effects;

[0004] When the device in the above scheme is used, it is placed directly on the rail and moves along the rail to perform the detection task. However, the device relies on the H-shaped track wheel to slide on the rail, which makes it difficult to ensure the stability of the device during movement. Due to the vibration that may be generated during the movement, the pulley may be separated from the rail, which will have an adverse effect on the detection result of the distance sensor and reduce the accuracy of the detection. Utility Model Content

[0016] Beneficial Effects

[0017] The utility model provides a track detection and maintenance device. Compared with the prior art, it has the following

[0018] Beneficial effects:

[0019] (1) When the device is placed on the rail as a whole, and the single-sided track wheel is placed on the top surface of the rail, the extension frame on the slide is driven to move by rotating the knob bolt, so that the ball on the extension frame contacts the waist of the rail, thereby limiting the position of the device as a whole to avoid shaking during movement and affecting detection.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution for a track detection and maintenance device: a track detection and maintenance device, comprising a main frame 1, a detection mechanism 2 is provided on the main frame 1 and is used to detect the flatness of the rail surface, a guide mechanism 3 is provided on the main frame 1 and is used to ensure the stability of the main frame 1 during movement, and the guide mechanism 3 includes:

[0028] The mobile assembly 31 includes a frame body 312 rotatably mounted at four corners of the bottom of the main frame 1 through a rotating shaft 311, a wheel frame 313 is fixed at the bottom of the frame body 312, and a single-side track wheel 314 is rotatably mounted inside the wheel frame 313;

[0029] The positioning assembly 32 includes a slide 321 installed in a transverse sliding manner in the frame 312 . A knob bolt 322 is threadedly installed on the inner end of the slide 321 , and the knob bolt 322 is rotatably connected to the frame 312 . An extension frame 323 is fixed to the bottom of the outer end of the slide 321 .

[0030] In this embodiment, when the entire device is placed on the rail, and the single-sided track wheel 314 is placed on the top surface of the rail, the extension frame 323 on the slide 321 is driven to move by rotating the knob bolt 322, so that the lower end of the extension frame 323 is placed at the waist of the rail, thereby limiting the position of the entire device to avoid shaking during movement and affecting detection.

[0031] Specifically, a ball bearing 324 is installed inside the lower end of the extension frame 323 .

[0032] In this embodiment, the lower end of the extension frame 323 is in contact with the waist of the rail through the ball bearing 324 to reduce the friction.

[0033] Specifically, the testing organization 2 includes:

[0034] The actuator assembly 21 includes a sleeve frame 211 fixed on both sides of the rear end of the main frame 1, a bracket 212 is fixed to the rear end of the sleeve frame 211, and a distance sensor 213 is installed inside the upper end of the bracket 212;

[0035] The auxiliary component 22 includes a detection rod 221 that is slidably installed inside the sleeve frame 211, a guide wheel 222 is installed at the bottom of the detection rod 221, a docking joint 223 is installed on the top of the detection rod 221 and is used in conjunction with the distance sensor 213, and a baffle 224 is fixed to the outer wall of the lower end of the detection rod 221.

[0036] In this embodiment, when the main frame 1 moves along the rail through the guide mechanism 3, it also drives the guide wheel 222 to roll along the rail. When passing through an uneven area on the rail, the guide wheel 222 moves up or down, and at the same time drives the docking joint 223 on the detection rod 221 to move up or down, so that the distance between the docking joint 223 and the distance sensor 213 changes, thereby realizing the detection of the flatness of the rail surface.

[0037] Specifically, the auxiliary component 22 further includes a plurality of rollers 225 rotatably mounted on four surfaces of the outer wall of the detection rod 221 .

[0038] In this embodiment, when the detection rod 221 slides along the sleeve frame 211 , the roller 225 is driven to roll along the inside of the guide groove 214 , thereby improving the smoothness of the detection rod 221 in the process of moving up and down.

[0039] Specifically, the actuator 21 further includes guide grooves 214 which are formed on four surfaces of the inner wall of the sleeve 211 and cooperate with the rollers 225 .

[0040] In this embodiment, the roller 225 is limited by the guide groove 214 so that the detection rod 221 always moves vertically when sliding along the detection rod 221 .

[0041] Specifically, the detection mechanism 2 further includes a spring 23 sleeved and mounted on the detection rod 221 , and the spring 23 is located between the bottom of the sleeve frame 211 and the top of the baffle 224 .

[0042] In this embodiment, the rebound pressure of the spring 23 pushes the baffle 224 to drive the guide wheel 222 on the detection rod 221 to move downward, so that the guide wheel 222 can always fit the surface of the rail.

[0043] The working principle and use process of the utility model are as follows: first, when the device is placed on the rail as a whole, and the single-side track wheel 314 is placed on the top surface of the rail, the extension frame 323 on the slide 321 is driven to move by rotating the knob bolt 322, so that the ball 324 on the extension frame 323 contacts the waist of the rail, thereby limiting the position of the device as a whole to avoid shaking during the movement and affecting the detection;

[0044] Then, when the device moves along the rail, it drives the guide wheel 222 to roll along the rail. When passing through an uneven area on the rail, the guide wheel 222 moves up or down, and at the same time drives the docking joint 223 on the detection rod 221 to move up or down, so that the distance between the docking joint 223 and the distance sensor 213 changes, thereby realizing the detection of the flatness of the rail surface.

[0045] The model of the distance sensor is: LDM4X. As it adopts existing mature technology products, it will not be elaborated in detail here. All the electrical components appearing in this article are connected to the external main controller and 220V AC power.

Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
