Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to a positioning device for tunnel measurement. Background Art

[0002] Tunnel engineering surveying is the surveying carried out at various stages of tunnel engineering planning, survey and design, construction and operation management.

[0003] In the related art, the method of construction measurement in a tunnel is generally carried out using optical instruments. First, multiple control points are inserted on the ground of the tunnel to form a control network. A total station is set up at one control point, and a prism is set up at another control point. The light emitted by the total station is reflected by the prism to complete the measurement of the control points in the tunnel. The measurement of the control points plays a decisive role in the penetration of the tunnel. The current existing control point arrangement in the tunnel is not convenient for arranging the arrangement points, and the installation and hanging of the prism is relatively complicated.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a positioning device for tunnel measurement. Figure 1 and Figure 2 The positioning device for tunnel measurement includes a mounting tube 1, which is used to be inserted into a hole punched in the inner wall of the tunnel, so as to fix the position of the mounting tube 1 and facilitate the connection of other components with the mounting tube 1 to complete the positioning; the side wall of the mounting tube 1 is formed, and the end of the mounting tube 1 used to be inserted into the hole is sealed, and the end of the mounting tube 1 sealed is provided with a mounting guide surface 11, and the mounting guide surface 11 makes the end of the mounting tube 1 pointed, which is convenient for inserting the mounting tube 1 into the hole, and at the same time, the outer wall of the mounting tube 1 close to the mounting guide surface 11 is close to the axis of the mounting tube 1, and the outer wall of the mounting tube 1 away from the mounting guide surface 11 is away from the axis of the mounting tube 1, so that the installation process of the mounting tube 1 is facilitated, and at the same time, the diameter of the outer wall gradually increases, which enhances the stability of the mounting tube 1 in the hole and reduces the possibility of the mounting tube 1 detaching.

[0031] Reference Figure 1 and Figure 2The end of the mounting tube 1 is detachably connected to the cleaning tube 2 by means of a threaded connection. At the same time, the mounting tube 1 is hollow, and the outer wall of the cleaning tube 2 is threadedly connected to the inner wall of the mounting tube 1. The end of the cleaning tube 2 away from the mounting tube 1 is rotatably connected to a connecting head 3 by a rotating shaft. The connecting head 3 is detachably connected to a clamping ring 4 by means of a threaded connection. The clamping ring 4 is used to connect to a positioning net or a measuring device, thereby making the installation of the measuring device more convenient.

[0032] Reference Figure 1 and Figure 2 The adjusting ring 5 is screwed to the side wall of the connecting head 3, and the adjusting ring 5 is screwed to the side wall of the connecting head 3, so that the adjusting ring 5 and the connecting head 3 are coaxially arranged. The adjusting ring 5 is fixed with an adjusting rope 6 on the outer wall of the adjusting ring 5 by bolts. In this embodiment, the adjusting rope 6 is a wire rope, and an adjusting rod 7 is fixed to the end of the adjusting rope 6 by bonding. A plurality of adjusting holes 8 are provided on the side wall of the cleaning cylinder 2, and the adjusting holes 8 are used to pass the adjusting rod 7. At the same time, the adjusting rod 7 is threadedly connected to the inner wall of the adjusting hole 8. By passing the adjusting rod 7 through different adjusting holes 8, the length of the adjusting rope 6 can be adjusted, the angle between the connecting head 3 and the cleaning cylinder 2 can be controlled, so as to control the position of the clamping ring 4, which is convenient for fixing the measuring device at the desired position, and reduces the possibility that the measuring device is not easy to be installed to the desired position due to different hole depths or different hole positions. At the same time, the side wall of the connecting head 3 is provided with a thread, so that the adjusting ring 5 is threadedly connected to the side wall of the connecting head 3, and the position of the adjusting ring 5 on the connecting head 3 can be adjusted by rotating the adjusting ring 5, so as to adjust the length of the connecting rope.

[0033] Reference Figure 1 and Figure 2 The cleaning cylinder 2 is hollow, and a plurality of cleaning grooves 9 are provided on the side wall of the cleaning cylinder 2. The plurality of cleaning grooves 9 are evenly distributed around the axis of the cleaning cylinder 2. At the same time, the length direction of the cleaning grooves 9 is parallel to the axis direction of the cleaning cylinder 2. The cleaning grooves 9 penetrate the side wall of the cleaning cylinder 2 along the radial direction of the cleaning cylinder 2. At the same time, a cleaning block 15 is fixed to the same side wall through an integrated molding method. The cleaning block 15 is provided with a cleaning guide surface 10 toward the end of the mounting cylinder 1. The cleaning guide surface 10 is inclined. The side wall of the mounting cylinder 1 is also provided with a cleaning groove 9, so that the soil particles destroyed by the mounting cylinder 1 during the installation process can slide into the cleaning groove 9 on the cleaning cylinder 2 under the action of the cleaning guide surface 10, thereby being discharged, thereby reducing the possibility that the mounting cylinder 1 is difficult to install due to the accumulation of soil particles in the hole.

[0034] Reference Figure 1 and Figure 2An opening 12 is provided on the clamping ring 4 to facilitate the installation process. At the same time, a closing rod 13 is rotatably connected to the opening 12 on the clamping ring 4 through a rotating shaft. The end of the closing rod 13 is fixed with a limiting plate 14 by an integral molding method. When the limiting plate 14 is arranged in an arc shape and the inner side wall of the limiting plate 14 abuts against the side wall of the clamping ring 4, the closing rod 13 cannot move. A reset spring is provided at the end of the closing rod 13. The reset spring is used to drive the closing rod 13 to rotate, so that the closing rod 13 remains in a sealed state with the clamping ring 4, reducing the possibility of the measuring device automatically detaching after installation and enhancing stability.

[0035] The implementation principle of a positioning device for tunnel measurement in an embodiment of the present application is as follows: after assembling the installation tube 1 and the cleaning tube 2, the installation tube 1 is inserted into the drilled hole, and the length of the connecting rope is adjusted so that the connecting head 3 is at a suitable angle. At this time, the connecting head 3 is at a suitable height. At this time, the measuring device is connected to the clamping ring 4, so that the measuring device is installed in a suitable position, reducing the possibility that the measuring device is difficult to install in the specified position due to the influence of the curvature of the inner wall of the tunnel or the influence inside the hole.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
