Description

Technical Field

[0001] This utility model relates to the field of tunnel blasting technology, specifically a tunnel blasting borehole positioning mechanism. Background Technology

[0002] Tunnels are key and critical projects in the construction of highways and railways. With the development of railway construction and the advancement of technology, tunnel excavation methods have developed rapidly. Commonly used excavation methods include drill-and-blast, shield tunneling, and tunnel boring machine (TBM) excavation. Because the drill-and-blast method is highly adaptable to geological conditions and has low excavation costs, it is particularly suitable for the construction of tunnels in hard rock, broken rock, and a large number of short tunnels. Therefore, the drill-and-blast method is still the commonly used tunnel excavation method at home and abroad.

[0003] According to a search report from a novelty search agency, announcement number CN221271134U discloses a tunnel blasting drilling positioning mechanism, including a mounting shell. A mounting frame is fixedly connected to the bottom of the mounting shell, and multiple anti-slip wheels are rotatably connected to both sides of the mounting frame. A mounting plate is fixedly connected to one side of the mounting shell, and a motor is fixedly connected to the inner wall of one side of the mounting shell. The output shaft of the motor passes through one side of the mounting plate and is fixedly connected to a rotating disk. A rectangular block is fixedly connected to one side of the rotating disk. The mechanism is simple to use. Rotating the bidirectional screw causes two frosted contact plates to move away from each other and abut against the inner wall of the tunnel, braking the mounting shell. Starting the motor drives the electric nozzle and the straight plate to rotate. The electric nozzle can rotate 360 ​​degrees and can be painted on the tunnel wall for marking. After rotation stops, the straight plate, in conjunction with the scale, allows for positioning based on the rotation angle of the electric nozzle.

[0004] The aforementioned technology discloses a tunnel blasting drilling positioning mechanism that can adjust the electric spray head to the required angle according to the positioning needs and scale for painting positioning work. However, it still has the following shortcomings in use:

[0005] 1. The electric nozzles and electric telescopic rods used for adjusting position and painting are directly exposed when not in use, posing a significant risk of accidental damage. There is a lack of safety protection for the electric nozzles and electric telescopic rods after use, resulting in unsatisfactory safety when not in use. 2. There is a lack of a structure for integrated cleaning of the electric nozzles after use, which may affect their future use. Therefore, this application proposes a tunnel blasting drilling positioning mechanism to address the aforementioned problems. Utility Model Content

The inner ring of the first bearing is fixedly fitted with the outer side of the circular protective cover 3, which achieves the effect of rotating the circular protective cover 3. Two L-shaped handles are fixedly connected to the top left side of the trolley base plate 1.

[0028] A rotary drive assembly is fixedly connected between the inside of the circular cover 3 and the top left side of the dial 2. An L-shaped pointer 302, matching the protractor scale, is fixedly connected to the top left side of the circular cover 3. A storage hole 301 is provided on the top of the circular cover 3. An electric telescopic rod 5 is fixedly installed on the inner right side of the circular cover 3. An electric spray head 501 located in the storage hole 301 is fixedly connected to the extended end of the electric telescopic rod 5. A water tank 604 and a paint storage tank 603 are fixedly installed on the top of the trolley base plate 1. The electric telescopic rod 5... A water-paint switchable suction assembly for supplying water or paint to the electric spray head 501 when it is started is fixedly installed on the left side. The bottom end of the water-paint switchable suction assembly extends into the water tank 604 and the paint storage tank 603. Addition pipes are fixedly connected to the top left side of both the water tank 604 and the paint storage tank 603. The right side of the paint storage tank 603 is fixedly connected to the left side of the dial 2. A first storage battery is fixedly installed on the bottom inner wall of the circular cover 3. A through hole is opened on the bottom inner wall of the circular cover 3, and the charging port of the first storage battery is located in the through hole. Both the telescopic rod 5 and the electric nozzle 501 are electrically connected to the first battery via flexible wires. Wireless remote control switches are fixed to the front of both the telescopic rod 5 and the electric nozzle 501 and electrically connected to them. Two wireless remote control switches are matched with the same external remote control, facilitating remote control of the telescopic rod 5 and the electric nozzle 501. The rotary drive assembly drives the circular cover 3 to rotate. The electric telescopic rod 5 rotates with the circular cover 3 to adjust the positioning angle of the electric nozzle 501, and also drives the electric nozzle 501 to move out or in. The L-shaped pointer 302 rotates with the circular cover 3 and measures the rotation angle using a protractor scale. The water-based paint suction assembly performs paint suction when the electric nozzle 501 is started, allowing for clear positioning during paint spraying, facilitating drilling by subsequent workers. After use, it switches to water suction mode to clean the paint channel and the electric nozzle 501.

[0029] Specifically, the rotary drive assembly includes an internal gear ring 4 fixedly fitted inside a circular cover 3. A gear 401 meshes with the top inner side of the internal gear ring 4. A brake motor 402 with its output shaft fixedly connected to the left side of the gear 401 is fixedly installed on the top left side of the dial 2. A circular through hole is provided on the top left side of the dial 2, and a second bearing is fixedly fitted inside the circular through hole.

A second battery electrically connected to the brake motor 402 is fixedly installed on the left side of the dial 2. The internal gear ring 4, gear 401, and brake motor 402 work together to drive the gear 401 to rotate, which in turn drives the internal gear ring 4 to rotate. The rotation of the internal gear ring 4 drives the circular cover 3 to rotate and adjust.

[0030] Furthermore, the water-based paint switchable suction assembly includes an L-shaped tube 503 fixedly installed on the left side of the electric telescopic rod 5. A flexible hose 502 is fixedly connected between the top of the L-shaped tube 503 and the inlet end of the electric spray head 501. A horizontal tube 6 with a sealing structure at the left end is rotatably fitted on the L-shaped tube 503. Three sealing bearings are fixedly fitted between the inner side of the horizontal tube 6 and the outer side of the L-shaped tube 503, which achieves the effect of sealing and rotating the L-shaped tube 503. The horizontal tube 6 is located inside the internal gear ring 4. A through hole is opened at the center of the right side of the scale 2, which is fixedly connected to the outer side of the horizontal tube 6. Two valves 601 are fixedly connected to the bottom of the horizontal tube 6. The bottom ends of the two valves 601 are fixedly connected to suction pipes 602. The bottom ends of the two suction pipes 602 extend into the water tank 604 and the paint storage tank 603, respectively. The L-shaped tube 503, flexible hose 502, horizontal tube 6, valves 601 and suction pipes 602 work together to utilize the paint spraying... During the clear positioning process, the operator opens the valve 601 on the right and closes the valve 601 on the left. When the electric spray head 501 is started, the paint in the paint storage tank 603 is drawn sequentially through the hose 502, L-shaped tube 503, horizontal tube 6, right valve 601, and right suction tube 602, and sprayed onto the location to be clearly positioned. After the multi-point spray positioning is completed by adjusting the angle, during cleaning, the left valve 601 is opened and the right valve 601 is closed. At this time, when the electric spray head 501 is started, it changes to drawing water from the water tank 604 sequentially through the hose 502, L-shaped tube 503, horizontal tube 6, left valve 601, and left suction tube 602, and spraying it out. The water flows through the paint passage formed by the hose 502, L-shaped tube 503, and horizontal tube 6, as well as inside the electric spray head 501, to perform the cleaning work, achieving the effect of cleaning the paint passage and electric spray head 501 in one go after use.

[0031] The usage method of this embodiment is as follows: In tunnel blasting positioning work, the personnel first push the device to the position to be positioned inside the tunnel, and then step on and lock the locking universal wheel 101. When positioning at multiple points, first adjust the angle of the electric nozzle 501 according to the first position to be positioned. During adjustment, start the brake motor 402 to drive the gear 401 to rotate. The gear 401 drives the circular guard 3 to rotate through the meshing internal gear ring 4. The circular guard 3 drives the electric telescopic rod 5 to rotate. The electric telescopic rod 5 drives the electric nozzle 501 and the L-shaped tube 503 to rotate as a whole. The circular guard 3 also drives the L-shaped pointer 302 to rotate. By observing the position of the L-shaped pointer 302 aligned with the angle measuring scale line on the dial 2, the personnel can accurately judge the adjustment angle. After the adjustment is appropriate, turn off the brake motor 402 and use the external... The remote control starts the electric telescopic rod 5, which drives the electric spray head 501 to move outward from the storage hole 301. When it moves to the appropriate length, the electric telescopic rod 5 is closed, the valve 601 on the right is opened and the valve 601 on the left is closed, and the electric spray head 501 is started. When the electric spray head 501 is started, it sequentially draws paint from the paint storage tank 603 through the hose 502, L-shaped tube 503, horizontal tube 6, valve 601 on the right and suction tube 602 on the right, and sprays it to the place that needs to be positioned for clear positioning. Then the brake motor 402 can be started again to rotate to the next angle that needs to be painted for painting positioning. This process is repeated to achieve multi-point clear positioning. Then the device can be unlocked and removed, and personnel can use drilling equipment to drill holes at the painting positioning position.

[0032] After the paint spraying positioning is completed, the operator opens the valve 601 on the left and closes the valve 601 on the right, then restarts the electric spray head 501. At this time, the electric spray head 501 switches to drawing water from the water tank 604 and spraying it out through the hose 502, L-shaped pipe 503, horizontal pipe 6, left valve 601, and left suction pipe 602 in sequence. The water flows through the paint passage formed by the hose 502, L-shaped pipe 503, and horizontal pipe 6, as well as within the electric spray head 501, to perform cleaning. This achieves the effect of cleaning the paint passage and electric spray head 501 in one go after use, reducing the phenomenon of paint residue solidifying at the end of the electric spray head 501 and affecting the next use, thus improving the usage effect. In addition, the paint storage tank 603 is fixed and does not rotate. Compared with the existing paint storage tank 603 rotating with the paint, this prevents the paint from shaking and splashing out due to the paint storage tank 603 rotating with the paint, or makes it difficult to draw out stably when the paint is low, thus making the use more stable.

[0033] After use, the electric telescopic rod 5 is reversed to drive the electric spray head 501 into the storage hole 301. At this time, the circular cover 3 protects the adjustment and painting structure of the electric telescopic rod 5 and the electric spray head 501, achieving the effect of safe storage and shielding protection of the adjustment and painting structure of the electric telescopic rod 5 and the electric spray head 501 after use, reducing the possibility of accidental damage when they are directly exposed to the outside and improving safety when not in use.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
