DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0029] The utility model discloses a measuring vehicle for installing a tunnel emergency evacuation platform. Figure 1-9 As shown, it includes a positioning plate assembly 1, a positioning bracket 4, an adjustment mechanism and a measuring vehicle. Among them, one end of the positioning bracket 4 is connected to the positioning plate assembly 1, and the positioning plate assembly 1 is in contact with the inner wall of the tunnel. The other end of the positioning bracket 4 is connected to the measuring vehicle through the adjustment mechanism. An assembly tray 17 is installed on the measuring vehicle, and a laser level is installed on the assembly tray 17. The measuring vehicle is set on a track, and the track is laid in the tunnel. The working principle and advantage of the present utility model are: during the construction of the tunnel emergency evacuation platform, it is necessary to fix a plurality of support frames on the inner wall of the tunnel at intervals along the extension direction of the tunnel to realize the basic support function of the tunnel emergency evacuation platform, and then the platform is built on these support frames. Since the bending, undulation and deflection of the tunnel are unpredictable during the installation of the support frames, it is necessary to use the present utility model to accurately define the installation height of the support frames and the length of the upper and lower ends of the support frames, so that the installed tunnel emergency evacuation platform achieves the predetermined effect. Specifically, the present invention realizes measurement of different positions of the tunnel by measuring the vehicle body walking on the track; when the predetermined installation position of the support frame is reached, the measurement of the vehicle body is stopped, and the adjustment mechanism is controlled to adjust the height of the positioning bracket 4 so that the preset installation height of the support frame is reached, and the positioning bracket 4 is horizontally calibrated by a laser level, and then the positioning bracket 4 is controlled to extend horizontally toward the inner wall of the tunnel until the positioning plate assembly 1 contacts the inner wall of the tunnel, and then a ruler is used to measure the distance from the upper end of the positioning plate assembly 1 to the predetermined position of the positioning bracket 4 and the distance from the lower end of the positioning plate assembly 1 to the predetermined position of the positioning bracket 4, thereby obtaining the length of the upper and lower ends of the support frame, and then a support frame of corresponding size is made to ensure that the constructed tunnel emergency evacuation platform meets the requirements. In summary, the utility model can accurately measure the installation height of the support frame and determine the size and specifications of the support frame, so that the accuracy of the constructed tunnel emergency evacuation platform is higher. The height and size of the installed support frame can be changed accordingly as the height and extension direction of the track change, so that the constructed tunnel emergency evacuation platform also changes accordingly, and the space for train travel will not be blocked.

[0030] As a preferred embodiment of the present invention, Figure 1 、 8As shown, a connecting seat is constructed on the positioning plate assembly 1, and one end of the positioning bracket 4 is connected to the connecting seat via a pin shaft 3.

The measuring vehicle body of this embodiment includes a frame 15 connected to the adjustment mechanism, and two sets of wheel assemblies 16 are respectively installed on both sides of the lower end of the frame 15. The two sets of wheel assemblies 16 located on one side of the frame 15 roll on the corresponding single rail of the track. An assembly tray 17 is installed on the frame 15, and a laser level is installed on the assembly tray 17. This embodiment uses a laser level to perform horizontal correction. When the positioning bracket 4 is deflected, the deflection angle of the positioning bracket 4 is determined, and then the positioning bracket 4 is leveled, thereby preventing the support frame from being installed deflected, and ultimately preventing the tunnel emergency evacuation platform from being installed deflected.

[0031] As a preferred embodiment of the present invention, Figure 2 、 3 As shown, the wheel assembly 16 includes a wheel body rotatably mounted on a mounting shaft 24, the axis of which coincides with the axis of the wheel body. One end of the mounting shaft 24 extends transversely into the lower sidewall of the vehicle frame 15.

A third metal washer 21 and a fourth metal washer 22 are mounted on the fixing bolt 23, and the third and fourth metal washers 21 and 22 are compressed between the fixing bolt 23 and the axial end of the mounting shaft 24. The wheel assembly 16 of this embodiment not only limits the lateral position of the measuring vehicle on the track, but also allows the positioning plate assembly 1 to be disengaged from the tunnel inner wall when the tunnel emergency evacuation platform is subsequently relocated, allowing the measuring vehicle to travel on the track.

[0032] As a preferred embodiment of the present invention, Figure 1As shown, the positioning bracket 4 includes a connecting arm 8 extending laterally along the track, and a measuring positioning ring 6 is mounted on the connecting arm 8 for locating the distance between the tunnel emergency evacuation platform to be installed and the track. The distance measured by the above-mentioned ruler is the horizontal distance between the measuring positioning ring 6 and the upper end and the lower end of the connecting seat. A fastening bolt 5 is threadedly connected to the measuring positioning ring 6, and the fastening bolt 5 is locked on the connecting arm 8. By loosening the fastening bolt 5, the position of the measuring positioning ring 6 on the connecting arm 8 is adjusted. In this embodiment, a pull ring 7 for lifting is connected to the connecting arm 8. One end of the wire rope is connected to the pull ring 7, and the other end of the wire rope is connected to one of the plate rulers 9 of the adjustment mechanism. The wire rope is in a tensioned state. By adjusting the length of the wire rope, the positioning bracket 4 can be leveled.

[0033] As a preferred embodiment of the present invention, Figure 1 、 5 As shown in Figures 9 and 9, the adjustment mechanism includes plate rulers 9 spaced apart along the length of the connecting arm 8. Two plate rulers 9 are detachably connected to the upper end of the measuring vehicle. Two connecting screws 12 are fixed side by side to the measuring vehicle. Each connecting screw 12 extends vertically and has its upper end passed through an assembly bracket 17. Two locking nuts 30 are threaded onto the connecting screws 12 and tightened onto opposite end surfaces of the assembly bracket 17. In this embodiment, each plate ruler 9 is connected to the connecting arm 8 via a locking assembly. A vertical adjustment assembly is installed between the locking assembly and the plate ruler 9. In this embodiment, the locking assembly locks the connecting arm 8 and the plate ruler 9. When the locking assembly is released, the vertical and lateral relative positions of the plate ruler 9 and the connecting arm 8 can be adjusted. After adjustment is complete, the locking assembly is locked to the connecting arm 8. When the relative position of the plate ruler 9 is adjusted, the plate ruler 9 drives the measuring vehicle to move laterally and / or vertically.

[0034] As a preferred embodiment of the present invention, Figure 1 、 5 As shown in Figures 7 and 8, a first strip-shaped hole extending along the length of the connecting arm 8 is formed. The locking assembly includes a locking handwheel 14, which is threadedly connected to a connecting rod. The connecting rod extends perpendicularly through the first strip-shaped hole in a horizontal direction. A lead screw nut 29 is configured at the end of the connecting rod away from the locking handwheel 14. In this embodiment, the locking handwheel 14 is rotated to gradually approach the connecting arm 8 until it is locked onto the connecting arm 8, thereby achieving locking.

[0035] As a preferred embodiment of the present invention, Figure 6 、 7As shown in Figures 9 and 10, the vertical adjustment assembly includes a vertically arranged adjustment screw 28. The upper portion of the adjustment screw 28 is rotationally connected to the plate ruler 9 via a rolling bearing 27. A thrust bearing cap 11 is detachably connected to the upper end of the plate ruler 9 and secured to the upper end of the plate ruler 9 via a locking bolt 26. In this embodiment, the upper end of the adjustment screw 28 is coaxially assembled with the operating handwheel 10 via a fastening nut 25. The operating handwheel 10 is mounted with a handle 13. The adjustment screw 28 is threadedly connected to a screw nut 29. In this embodiment, a vertically extending slot 32 is constructed on the plate ruler 9, and the screw nut 29 is slidably assembled within the slot 32. A second vertically extending strip hole is formed in the plate ruler 9, through which the connecting rod passes. In this embodiment, the operating handwheel 10 is rotated to drive the adjustment screw 28. During rotation, the adjustment screw 28, due to its threaded connection with the screw nut 29, moves vertically within the guide slot 32 of the plate ruler 9, thereby adjusting the vertical relative position of the connecting arm 8 and the measuring vehicle body, so that the connecting arm 8 reaches a predetermined height, thereby facilitating the measurement and determination of the support frame specifications at the corresponding location in the tunnel. In this embodiment, the plate ruler 9 is moved laterally by moving the locking assembly and the plate ruler 9 along the length of the first strip hole. After adjustment, the locking handwheel 14 is tightened.
