Description

Technical Field

[0001] The present application relates to the technical field of tunnel blasting, and in particular to a tunnel blasting blasthole positioning and setting-out device. Background Art

[0002] Tunnel blasting is an important part of drill and blast tunneling. The location of tunnel blasting holes affects the blasting effects such as tunnel over-break, under-break, and rock blockiness.

[0003] Before tunnel blasting, a laser total station is needed to locate and lay out the blastholes. However, most existing laser projectors use a tripod for on-site positioning. Due to the large size of the tripod and the laser, it is very inconvenient to carry deep into the tunnel. In tunnels with dense blastholes, the bulky size of the equipment is very inconvenient, thus affecting construction efficiency. Utility Model Content

At the same time, the horizontal setting of the staking out camera can be adjusted by adjusting the position of the adjusting rod on the movable frame, and the position of the staking out camera in the vertical direction can be adjusted by adjusting the position of the connecting piece on the adjusting rod, which is convenient for adjusting the position of the staking out camera, thereby facilitating the construction process.

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

[0030] The present application embodiment discloses a tunnel blasting hole positioning and setting out device. Figure 1 and Figure 2 The tunnel blasting blasthole positioning and staking out device includes a mobile frame 1, the bottom of the mobile frame 1 is rotatably connected with a mobile wheel through a rotating shaft, the mobile wheel facilitates the sliding of the mobile frame 1, an adjusting rod 2 is slidably provided on the mobile frame 1, a connecting piece 15 is slidably provided on the side wall of the adjusting rod 2, and a staking out camera 3 is detachably connected to the side wall of the connecting piece 15 by bolt fixing, the connecting piece 15 can move on the side wall of the adjusting rod 2 along the axial direction of the adjusting rod 2, the height of the staking out camera 3 can be adjusted by adjusting the position of the connecting piece 15, and the horizontal position of the staking out camera 3 can be adjusted by adjusting the position of the adjusting rod 2 on the mobile frame 1, thereby completing the adjustment of the position of the staking out camera 3, because the overall structure is relatively simple, it occupies less space, which is convenient for the positioning and staking out process in the tunnel.

[0031] Reference Figure 1 and Figure 2, a moving groove 11 is provided on the moving frame 1, a moving plate 12 is arranged in the moving groove 11, and the moving plate 12 is slidably connected to the inner side wall of the moving groove 11, that is, a moving plate 12 is slidably arranged in the moving groove 11, and the moving plate 12 can slide in the sliding groove along the length direction of the sliding groove, and the adjusting rod 2 is fixed to the end face of the moving plate 12 by bolts. By controlling the position of the moving plate 12 in the moving groove 11, the position of the adjusting rod 2 can be controlled, thereby adjusting the position of the layout camera 3; the adjusting rod 2 is hollow, and a thread is provided on the outer side wall of the end of the adjusting rod 2 away from the moving frame 1, and the side wall of the moving frame 1 is detachably connected with a placement box 9 by bolts. A plurality of extension rods 10 are placed in the box 9. The extension rods 10 are hollow, and the outer wall of one end of the extension rod 10 is provided with a thread, and the inner wall of the other end is provided with a thread. The diameter of the outer wall of the extension rod 10 is the same as the diameter of the outer wall of the adjusting rod 2. The extension rod 10 is used to extend the length of the adjusting rod 2 in the direction of its own axis. During use, the thread of the inner wall of the extension rod 10 is connected with the thread of the outer wall of the adjusting rod 2, thereby connecting the extension rod 10 and the adjusting rod 2. When it is necessary to continue to extend, the remaining extension rods 10 can be connected in sequence. Since the diameter of the outer wall of the extension rod 10 is the same as the diameter of the outer wall of the adjusting rod 2, the connection between the extension rod 10 and the connecting rod will not interfere with the movement of the connecting piece 15.

[0032] Reference Figure 1 and Figure 2The connecting member 15 includes a positioning ring 16 and a positioning rod 4. The adjusting rod 2 is penetrated by the positioning ring 16, and the inner wall diameter of the positioning ring 16 is larger than the outer wall diameter of the adjusting rod 2, so that the positioning ring 16 can move on the adjusting rod 2. A positioning hole 5 is provided on the side wall of the positioning ring 16. The positioning hole 5 penetrates the positioning ring 16 along the radial direction of the positioning ring 16. The positioning hole 5 is used to penetrate the positioning rod 4 and the positioning rod 4 can slide in the positioning hole 5 along the axial direction of the positioning hole 5. At the same time, a positioning spring 6 is provided in the positioning hole 5. One end of the positioning spring 6 is bonded to the inner wall of the positioning hole 5 and the other end is bonded to the side wall of the positioning rod 4. The positioning spring 6 is used to pull the positioning rod 4 toward the direction close to the axis of the positioning ring 16. During use, the positioning rod 4 is pulled to move the positioning rod 4 toward the direction away from the axis of the positioning ring 16. At this time, the positioning ring 16 can be adjusted on the adjusting rod 2. The end of the positioning rod 4 facing the axis of the positioning ring 16 is detachably connected with the protective cover 13 by bonding or clamping. The protective cover 13 is made of rubber. The protective cover 13 is used to enhance the friction between the end of the positioning rod 4 and the side wall of the adjusting rod 2, further reducing the possibility of the position of the connecting member 15 being offset; the end of the positioning rod 4 away from the axis of the positioning ring 16 is fixed with a driving plate 14 in an integrally formed manner. The diameter of the driving plate 14 is larger than the diameter of the positioning rod 4. The movement of the driving plate 14 is controlled to drive the positioning rod 4 to facilitate the process of pulling the positioning rod 4.

[0033] Reference Figure 1 and Figure 2 The side wall of the positioning rod 4 is connected to a reinforcing plate 7, and the end surface of the reinforcing plate 7 is fixed with a plurality of reinforcing strips 8 by bonding or clamping. When the positioning rod 4 abuts against the side wall of the adjusting rod 2, the reinforcing strips 8 abut against the side wall of the adjusting rod 2, thereby further improving the stability of the connecting member 15. The reinforcing plate 7 is connected to the side wall of the positioning rod 4 by a rotating shaft, and the end surface of the reinforcing plate 7 in contact with the positioning rod 4 is inclined. When the end surface is in contact with the side wall of the positioning rod 4, the reinforcing plate 7 is inclined. A return torsion spring is provided at the rotating shaft where the reinforcing plate 7 and the positioning rod 4 are rotatably connected. The return torsion spring is used to drive the end surface of the reinforcing plate 7 in contact with the positioning rod 4 to always move in the direction of abutting the side wall of the positioning rod 4, so that the reinforcing plate 7 is always inclined, thereby enhancing the contact area between the reinforcing plate 7 and the side wall of the adjusting rod 2, thereby enhancing the friction between the connecting member 15 and the adjusting rod 2, and reducing the possibility of displacement of the position of the connecting member 15.

[0034] The implementation principle of a tunnel blasting borehole positioning and staking out device in an embodiment of the present application is as follows: the height of the staking out camera 3 can be adjusted by adjusting the position of the connecting piece 15, and the horizontal position of the staking out camera 3 can be adjusted by adjusting the position of the adjusting rod 2 on the mobile frame 1, thereby completing the adjustment of the position of the staking out camera 3. Since the overall structure is relatively simple, it occupies less space, which is convenient for the positioning and staking out process in the tunnel.
