Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine (TBM) equipment, and in particular to a device for detecting track spacing of a TBM battery-powered vehicle. Background Technology

[0002] The shield tunneling battery vehicle is an indispensable transportation equipment in shield tunnel construction. It is mainly responsible for the transfer of materials inside the tunnel. It can transport the tunnel segments, steel bars, grouting materials and other materials needed for shield tunneling to the working face, as well as transport the excavated soil and waste materials out of the tunnel. It travels on rails and is an "underground transportation hub" to ensure the continuous and efficient progress of shield tunneling.

[0003] Existing detection devices for the track spacing of tunnel boring machine (TBM) battery-powered vehicles mostly employ laser ranging technology, which offers advantages such as high measurement accuracy and intuitive readings. Their structure typically includes a laser rangefinder, a support frame, and a reference plate. The laser rangefinder is fixed to the support frame and calculates the spacing by emitting a laser beam towards the reference plate on the other side of the track and using the reflected signal. Some devices also include a display screen to show the data in real time.

[0004] However, existing laser rangefinders are mostly exposed to the elements. The dust and debris inside shield tunnels can easily cause wear and tear on the instrument lenses or damage from impacts. After long-term use, the accuracy of the instruments is easily affected by dust pollution. Therefore, a device for detecting the track spacing of shield tunnel battery vehicles is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for detecting the track spacing of a shield tunneling battery vehicle, aiming to improve the problem that laser rangefinders in the prior art are easily affected by dust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for detecting track spacing of a shield tunneling battery vehicle includes two pillars, with a crossbar fixedly connected to the bottom of each pillar. A movable rod is slidably connected inside the crossbar, and an adjustment component is installed on the outside of the movable rod. A movable sleeve is slidably connected to one end of the movable rod. An mounting plate is installed at the bottom of each of the two movable sleeves. A guide wheel one and a guide wheel two are respectively installed at the bottom of the two mounting plates. A laser rangefinder is installed on the top of one mounting plate, and a protective component is installed on the outside of one of the movable sleeves.

[0008] The protective assembly includes a protective box, which is rotatably connected to the outside of a movable sleeve via a hinge.

Locking tongues are fixedly connected to the outside of each of the two adjusting plates. A groove is opened inside one of the mounting plates, and the locking tongue is engaged inside the groove. A spring is fixedly connected inside the adjusting plate.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes two sliders, which are fixedly connected to one end of the movable rod. Two grooves are opened on the outer side of the crossbar, and the sliders are slidably connected inside the grooves. Fixed blocks are fixedly connected to both ends of the crossbar, and screws are threaded into the interior of the fixed blocks. The screws abut against the outer side of the movable rod.

[0011] As a further description of the above technical solution:

[0012] A circular groove is provided on the outer side of the protective box;

[0013] As a further description of the above technical solution:

[0022] Each of the two support pillars has a handle fixedly connected to one end, and two reinforcing rods are fixedly connected between the two support pillars. A display screen is installed on the outside of the crossbar.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the protective box can effectively protect the laser rangefinder, significantly reduce the probability of contaminants adhering to the instrument surface, delay the aging of the instrument's optical components, and extend its service life.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0036] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 This utility model provides an embodiment of a device for detecting track spacing of a shield tunneling battery vehicle, comprising two support columns 1, with a crossbar 2 fixedly connected to the bottom of the two support columns 1, the crossbar 2 connecting the two support columns 1 into a whole. A movable rod 11 is slidably connected inside the crossbar 2, allowing it to slide flexibly within the crossbar 2, thus laying the foundation for subsequent adjustment of the device length to adapt to different track spacings. An adjustment component is installed on the outside of the movable rod 11, which is a key part for realizing the adjustment and fixation of the device length. A movable sleeve 13 is slidably connected to one end of the movable rod 11, and the movable sleeve 13 can move with the movable rod. The position is adjusted by the movement of 11 and its own sliding. The bottom of the two movable sleeves 13 is equipped with mounting plates 24. The bottom of the two mounting plates 24 is respectively equipped with guide wheels 14 and 15. Guide wheels 14 and 15 are in contact with the track, which facilitates the movement of the device on the track. They are also important components for positioning the two sides of the track. A laser rangefinder 20 is installed on the top of one mounting plate 24. The laser rangefinder 20 is the core component for measuring the track distance and can obtain the distance data. A protective component is installed on the outside of one movable sleeve 13. The protective component is specifically designed to protect the laser rangefinder 20.

[0037] The protective assembly includes a protective case 17, which is rotatably connected to the outside of a movable sleeve 13 via a hinge 16. The hinge 16 allows the protective case 17 to open and close flexibly, facilitating operation of the internal laser rangefinder 20. A housing 18 is fixedly connected to the outside of the protective case 17. Two adjusting plates 22 are slidably connected inside the housing 18, allowing them to slide within the housing 18. Locking tongues 23 are fixedly connected to the outside of each adjusting plate 22. The locking tongues 23 are crucial for locking the protective case 17. A mounting plate 24 has a groove 19 inside, and the locking tongues 23 engage with the inside of the groove 19. The locking tongue 23 engages with the groove 19 to securely fix the protective box 17. A spring 26 is fixedly connected inside the adjusting plate 22, which provides elastic force for the adjustment plate 22 and the locking tongue 23 to reset. A circular groove 21 is provided on the outside of the protective box 17. The position of the circular groove 21 corresponds to the measurement direction of the laser rangefinder 20. Its size and shape are designed to allow the laser emitted by the laser rangefinder 20 to pass through smoothly. This will not hinder the measurement operation, and the protective box 17 can effectively protect the laser rangefinder 20 without affecting the measurement, preventing dust and other debris from directly adhering to the instrument surface.

[0038] A partition 27 is fixedly connected inside the outer casing 18. The partition 27 divides the internal space of the outer casing 18 and restricts the spring 26 to prevent the spring 26 from sliding out. This ensures that the movement of the adjusting plate 22 and the locking tongue 23 is more reliable and that the locking and opening process of the protective box 17 is smooth. Two springs 26 are fixedly connected to both sides of the partition 27. A guide rod 25 is fixedly connected to the middle of the partition 27. The guide rod 25 provides a clear guide path for the extension and retraction of the springs 26. Both springs 26 are sleeved on the outside of the guide rod 25.

[0039] Reference Figure 1 , Figure 3 and Figure 4The adjusting assembly includes two sliders 6, which are fixedly connected to one end of the movable rod 11. Two grooves 5 are formed on the outer side of the crossbar 2, providing a path and guide for the sliders 6 to slide. The sliders 6 are slidably connected inside the grooves 5. Fixed blocks 7 are fixedly connected to both ends of the crossbar 2, providing support for the installation of the screw 9. The screw 9 is threadedly connected inside the fixed blocks 7, allowing the screw 9 to move axially by rotation. When the screw 9 moves to the position abutting the movable rod 11, the position of the movable rod 11 is fixed, thus allowing the device to... After adjusting the approximate length, it can be quickly fixed without multiple adjustments. The screw 9 abuts against the outside of the movable rod 11. The movable rod 11 has an abutment groove 12 inside. One end of the screw 9 is fixedly connected to a rubber block 10. The rubber block 10 is relatively soft and has a large friction, which can more stably fix and abut against the abutment groove 12, so that the movable rod 11 is fixed. The rubber block 10 abuts against the inside of the abutment groove 12. The end of the screw 9 away from the rubber block 10 is fixedly connected to a handle 8. The handle 8 is set to provide a convenient force application point for the operator to rotate the screw 9. The handle 8 is located on the outside of the fixed block 7.

[0040] Reference Figures 1-3 Each of the two support pillars 1 has a handle 3 fixedly connected to one end. The handle 3 is easy for the operator to hold and provides a convenient point of force for the operator when the device needs to be moved or pushed on the track, making the movement of the device more flexible. Two reinforcing rods 4 are fixedly connected between the two support pillars 1. The reinforcing rods 4 further strengthen the connection between the two support pillars 1 and improve the structural stability of the entire device. A display screen 28 is installed on the outside of the crossbar 2. The display screen 28 can be connected to the laser rangefinder 20 and can display the track spacing data measured by the laser rangefinder 20 in real time and intuitively, making it convenient for the operator to quickly read and record the data.

[0041] Working principle: First, when the distance needs to be measured, place the device on the track and slide the slider 6 to adjust the approximate length of the device so that the guide wheel 14 and guide wheel 2 15 are exactly on both sides of the track. Then, rotate the handle 8 to make the screw 9 rotate, so that the rubber block 10 just abuts against the movable rod 11, completing the initial adjustment. The initial adjustment can adjust the measuring distance of the device more quickly and accurately, without the need for multiple adjustments through adaptive extension as in the original method. This improves the measurement efficiency and prevents the guide wheel 14 and guide wheel 2 15 from getting too close to the guide rail, which could cause the device to jam. It also avoids measurement errors caused by excessive distance from the guide rail.

[0042] Secondly, when conducting distance measurement work in the tunnel, dust will adhere to the surface of the laser rangefinder 20, which will affect the measurement results. The protective box 17 can effectively protect the laser rangefinder 20. At the same time, the circular groove 21 will not hinder the measurement operation. When it is necessary to check the laser rangefinder 20, simply pinch the adjusting plate 22 to force the spring 26 to contract, which will drive the locking tongue 23 to disengage from the groove 19, and the protective box 17 can be opened and closed quickly, which is convenient for the maintenance of the laser rangefinder 20.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
