Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing equipment for the interface of a railway tunnel chute. Background Technology

[0002] Railway tunnel chutes used for overhead contact line installation are special fixing foundations pre-embedded in the tunnel lining. They are processed into an arc shape according to the radius of the tunnel surface and used with T-bolts to accurately fix the overhead contact line hanging columns, positioning devices and conductors.

[0003] After the tunnel lining is poured, if the width of the chute is not up to standard, the T-bolts will not be able to be inserted, directly affecting the stability of the contact wire components. Secondly, if the alignment of multiple chutes is inconsistent, precise alignment will be impossible when installing the hanging columns and positioning devices later. This will not only increase the workload of on-site adjustments but also cause uneven suspension of the contact wire. Therefore, it is necessary to conduct inspections and make timely corrections in advance. For example, the existing Chinese utility model patent with publication number CN222652091U, "A Detection Device for Pre-embedded Chutes in Contact Wire Tunnels," includes a movable plate with wheels at each of the four corners of its bottom. There is an adjustment platform with a detection plate mounted on top. Two sets of laser devices are slidably mounted on the detection plate, and a scale is set on the side of the detection plate. Therefore, when this application detects the width of the pre-embedded trough, it is necessary to turn on the laser instrument, push the laser mounting platform, and make the laser align with the trough to read the data from the scale. However, a large number of tunnel troughs are pre-embedded in the tunnel lining, and only a small number of tunnel troughs can be detected at a time. It is also impossible to detect whether several troughs in the tunnel are installed sequentially in the standard path, which makes the detection efficiency low. Moreover, when detecting tunnel troughs in the inner side lining of the tunnel, it is impossible to quickly adjust the projection angle of the laser instrument. Utility Model Content

[0004] The purpose of this invention is to provide a railway tunnel chute interface detection device, which can quickly detect the width and alignment of the chute through a laser emitter. With the help of an electric turntable, servo motor, and equipment mounting plate, the distance between the two laser beams can be flexibly adjusted. Multiple chutes can be measured at once, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A railway tunnel chute interface detection device includes a mobile platform, a carrier fixedly connected to the mobile platform, an electric turntable fixedly connected to the front of the carrier, a bracket fixedly connected to the front of the electric turntable, an installation platform fixedly connected to the bracket, a laser width detection module disposed on the installation platform, the laser width detection module further includes a plurality of bearings fixedly connected to the installation platform, and an equipment mounting plate movably connected between two adjacent bearings, a first base symmetrically fixedly connected to the lower end of the equipment mounting plate, and a connecting plate movably connected between the plurality of first bases, a laser emitter and an tilt sensor respectively fixedly connected to the laser width detection module, and the electric turntable, the laser emitter, and the tilt sensor are electrically connected to the main control module inside the mobile platform through connecting lines.

[0007] As a further preferred embodiment of this utility model, a servo motor is fixedly connected to the lower end of the mounting platform. The servo motor is electrically connected to the main control module inside the mobile platform through a connecting line. The output end of the servo motor is fixedly connected to a lead screw through a coupling and extends to the upper position of the mounting platform, thereby providing a power source for adjusting the angle of the two equipment mounting plates.

[0008] As a further preferred embodiment of this utility model, a second base is fixedly connected to one side of the bottom of the equipment mounting plate, and the second base is rotatably connected between two of the bearing seats by a pin.

[0009] As a further preferred embodiment of this utility model, a side stop bar is rotatably connected to one side of the shaft seat, and a first slide rail is provided inside the side stop bar. A limit bolt is threadedly connected to one side of the first base, and the limit bolt passes through the first slide rail, which can provide a stable guiding function for the equipment mounting plate during the angle adjustment process.

[0010] As a further preferred embodiment of this utility model, two first bases at the lower end of the same equipment mounting plate are respectively fixedly connected to side plates on opposite sides. The side plates are provided with second slides, which allow the two sides of the connecting plate to slide between several side plates, thereby adjusting the angle of the two equipment mounting plates synchronously by vertically moving the connecting plate.

[0011] As a further preferred embodiment of this utility model, a screw hole is provided at the center of the connecting plate, and connecting shafts are fixedly connected to both sides of the connecting plate. The front and rear sides of the connecting shafts are slidably connected to one of the second slide rails, and the screw hole is threadedly connected to a lead screw. When the servo motor is started, it drives the lead screw to rotate in the screw hole, which makes the connecting plate move vertically. This allows the angles of the two device mounting plates to be adjusted synchronously with several second slide rails, thereby adjusting the projection position of the laser emitter, that is, adjusting the width of the laser beams projected by the two laser emitters.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the laser emitter, in conjunction with the electric turntable, can flexibly adapt to the inspection requirements of tunnel curved surfaces, enabling the inspection of tunnel grooves at different locations inside the tunnel. Furthermore, the servo motor drives the lead screw to move the connecting plate, allowing for simultaneous adjustment of the angles of the two equipment mounting plates. This eliminates the need for repeated manual adjustments and allows for the adjustment of the distance between the two laser beams according to different types of groove standards, significantly improving inspection efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-6As shown, the present invention provides a railway tunnel chute interface detection device, including a mobile platform 1, a platform 2 fixedly connected to the mobile platform 1, an electric turntable 3 fixedly connected to the front of the platform 2, a bracket 4 fixedly connected to the front of the electric turntable 3, an installation platform 5 fixedly connected to the bracket 4, a laser width detection module 6 provided on the installation platform 5, the laser width detection module 6 also includes a plurality of bearing seats 7 fixedly connected to the installation platform 5, and an equipment mounting plate 8 movably connected between two adjacent bearing seats 7, a first base 9 symmetrically fixedly connected to the lower end of the equipment mounting plate 8, and a connecting plate 10 movably connected between the plurality of first base seats 9, a laser emitter 11 and an inclination sensor 12 fixedly connected to the laser width detection module 6 respectively, and the electric turntable 3, the laser emitter 11, and the inclination sensor 12 are electrically connected to the main control module inside the mobile platform 1 through connecting lines.

[0023] like Figure 3 As shown, a servo motor 13 is fixedly connected to the lower end of the mounting platform 5. The servo motor 13 is electrically connected to the main control module inside the mobile platform 1 through a connecting cable. The output end of the servo motor 13 is fixedly connected to a lead screw 14 through a coupling and extends to the upper position of the mounting platform 5, thereby providing a power source for the angle adjustment of the two equipment mounting plates 8.

[0024] like Figures 3-6 As shown, a second base 17 is fixedly connected to one side of the bottom of the equipment mounting plate 8. The second base 17 is rotatably connected between two bearing seats 7 via a pin. A side stop 15 is rotatably connected to one side of the bearing seat 7. A first slide rail 16 is provided inside the side stop 15. A limit bolt 22 is threadedly connected to one side of the first base 9, and the limit bolt 22 passes through the first slide rail 16. This provides a stable guiding function for the equipment mounting plate 8 during angle adjustment. Side plates 18 are fixedly connected to the opposite sides of the two first bases 9 at the lower end of the same equipment mounting plate 8. A second slide rail 19 is provided inside the side plate 18, allowing the two sides of the connecting plate 10 to slide between several side plates 18. The angles of the two device mounting plates 8 can be adjusted synchronously by vertically moving the connecting plate 10. A screw hole 20 is provided in the center of the connecting plate 10. Connecting shafts 21 are fixedly connected to both sides of the connecting plate 10. The front and rear sides of the connecting shafts 21 are slidably connected to one of the second slide rails 19. The screw hole 20 is threadedly connected to the lead screw 14. The servo motor 13 starts and drives the lead screw 14 to rotate in the screw hole 20, which makes the connecting plate 10 move vertically. This allows the angles of the two device mounting plates 8 to be adjusted synchronously with several second slide rails 19, thereby adjusting the projection position of the laser emitter 11, that is, adjusting the width of the laser beam at the projection point of the two laser emitters 11.

[0025] It should be noted that this utility model is a railway tunnel chute interface testing device. Before testing, the mobile platform 1 is moved to the location to be tested in the tunnel by the control computer, so that the device is located close to the center line in the tunnel. Then, several adjacent chutes on the top of the tunnel are selected as references. The servo motor 13 is started by the main control module in the mobile platform 1 through the control computer. The output end of the servo motor 13 drives the lead screw 14 to rotate in the screw hole 20 through the coupling. Thus, the height of the connecting plate 10 is adjusted by the forward and reverse rotation of the lead screw 14, so that the connecting plate 10 slides in the second slide rail 19 of two side plates 18 respectively through the connecting shafts 21 on both sides. Then, the device mounting plate 8 rotates around the second base 17 as the axis, so that the projection angle of the laser emitter 11 can be adjusted. Therefore, after adjusting the projection angle of the laser emitter 11, the laser emission... The emitter 11 projects two laser beams, which extend along the tunnel extension path to form two reference lines. Most of the pre-selected chutes are located at one or close to one of the reference lines (because the chutes are prefabricated and embedded in the tunnel, there will be errors in meeting the standard due to the impact of concrete during the pre-installation process). Thus, the moving platform 1 can be controlled to move at a constant speed along the preset path in the tunnel. At this time, the moving platform 1 drives the laser width detection module 6 to move synchronously through the platform 2, the electric turntable 3, and the installation platform 5, so that the reference lines projected by the two laser emitters 11 can move and extend synchronously. This allows the installation path of the pre-embedded chutes in the tunnel to be visualized directly in the tunnel, as well as whether the installation of some pre-embedded chutes has deviated from its path. It can also help detect whether the width of the tunnel chutes at the top of the tunnel is standard.

[0026] When inspecting the tunnel chute on the inner side of the tunnel, the projection distance of the two laser beams is adjusted as described above. Then, the main control module issues a command, and the electric turntable 3 drives the bracket 4 and the mounting platform 5 to rotate together. This adjusts the orientation of the laser width detection module 6, thereby enabling the inspection of the tunnel chute on the inner side of the tunnel.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
