Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drilling, in particular to a tunnel blasting positioning structure and blasting blasthole drilling equipment. Background Art

[0002] Tunnel drilling and blasting is a construction method that involves drilling holes on the working surface, placing explosives in the holes and detonating the crushing medium to excavate the tunnel. For large-scale tunnel construction, intelligent drilling vehicles are usually used to drill blasting holes, while in small tunnels, patios, shafts, quarries, and open-pit mines in special environments, shallow hole blasting and secondary blasting, manually operated pneumatic rock drills are often used for the drilling process. The rock drills are operated by the constructors to drill deep holes into the rock layer on the inner wall of the tunnel to form multiple groups of blasting holes, which are convenient for subsequent blasting projects.

[0003] The light and dust environment in the tunnel construction area are limited, especially for small tunnels that are not convenient for intelligent drilling vehicles to enter. In order to achieve the expected secondary blasting effect, construction workers are often required to repeatedly locate and measure when drilling blast holes, which greatly limits the efficiency of drilling blast holes. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a tunnel blasting positioning structure and a blasting blast hole drilling device that can facilitate tunnel blast hole positioning drilling.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a tunnel blasting positioning structure and blasting blasthole drilling equipment, including a frame, a transverse movement component, a longitudinal movement component and a drilling machine;

[0006] The transverse movement assembly includes an adjustment seat, and the adjustment seat is arranged on the top of the frame through a connecting piece;

[0007] The longitudinal movement assembly includes a rack, a movable block and a gear, wherein the rack is fixed above the adjustment seat, the movable block is slidably sleeved on the outside of the rack and the adjustment seat, a gear is rotatably arranged in the movable block, the gear is meshed with the rack, and the rotating shaft of the gear extends out of the movable block and a handle is fixed on the outside;

[0008] The drilling machine comprises a motor and a drill bit, wherein the motor is fixed above the movable block, and the drill bit is drivingly connected to the motor.

[0009] The beneficial effects of the above technical solution are: the movable block is moved longitudinally on the rack by rotating the gear with the handle, and the motor of the drilling rig is fixed on the movable block, that is, the drilling rig moves longitudinally with the movable block to achieve the purpose of drilling, the rack of the longitudinal movement component is fixed on the adjustment seat, and the transverse movement component can move transversely on the frame, that is, the drilling rig can adjust its position laterally in the tunnel. When the position of the tunnel blasting hole is changed, the horizontal positioning of the blasting hole is more convenient, thereby improving the efficiency of the drilling operation.

[0010] Furthermore, the rack is marked with length marks.

[0011] Beneficial effect: The depth of the drilling hole can be accurately determined by the length scale on the rack, so as to accurately reach the predetermined depth position of the blast hole and ensure the blasting effect.

[0012] The connecting part includes a bolt, and there are limit rods at the front and rear ends of the top of the frame. The adjustment seat is arranged between the limit rods at the front and rear ends. A transverse long hole is opened on the limit rod, and threaded holes are opened at both ends of the adjustment seat. The bolt passes through the long hole and is adapted to be connected with the threaded hole at the end of the adjustment seat.

[0013] Beneficial effect: The bolt mainly plays a positioning role. After the lateral movement of the adjusting seat is completed, it is locked and connected with the limit rod through the bolt to prevent the adjusting seat from moving when the drilling rig is working, thereby ensuring the lateral accuracy of the blasting hole drilling.

[0014] Furthermore, the limiting rod is an L-shaped angle steel, the adjustment seat is clamped between two L-shaped angle steels, and the openings of the L-shaped angle steels at the front and rear ends are opposite to each other.

[0015] Beneficial effect: The limit rod can fix the longitudinal position of the adjustment seat, preventing the longitudinal position deviation of the adjustment seat when it moves horizontally, thereby affecting the normal use of the drilling rig.

[0016] Furthermore, at least one of the limit rods at the front and rear ends is marked with a length scale line.

[0017] Beneficial effect: The lateral movement distance of the drilling rig can be accurately determined by the length scale on the limit rod, so as to accurately reach the predetermined lateral position of the blasthole, further ensuring the accurate positioning of the blasthole.

[0018] A support plate and a base are arranged below the frame, and the support plate and the base are connected via a hydraulic lifting rod.

[0019] Beneficial effect: The hydraulic lifting rod can move the frame vertically, that is, the drilling rig can also adjust its position vertically, which is more convenient for positioning and drilling operations of tunnel blasting holes.

[0020] Furthermore, there is an escape space between the support plate and the movable block.

[0021] Beneficial effect: When the drilling rig is operating, the movable block moves longitudinally, and the support plate avoids the movable block to prevent the contact between the support plate and the movable block from affecting the longitudinal movement of the movable block, thereby affecting the normal operation of the drilling rig.

[0022] Furthermore, a roller is installed at the bottom of the base.

[0023] Beneficial effect: It facilitates the movement and transportation of the entire frame, making the drilling rig more flexible in tunnel drilling operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment, the drilling of the tunnel blasting hole is achieved by a longitudinal movement assembly. After the drill bit 10 is aligned with the predetermined position of the hole, the handle 7 is turned. The handle 7 drives the gear 5 to move on the rack 3 through the rotating shaft 6, and the drill bit 10 is inserted into the tunnel wall. As the depth of the drill bit 10 increases, the exposed distance of the rear end of the rack 3 becomes longer. The rack 3 is marked with a length scale. The drilling construction personnel can accurately determine the depth of the drill hole through the length scale on the rack 3, thereby accurately reaching the predetermined depth position of the hole and ensuring the blasting effect.

The adjusting seat 2 is arranged between the limit rods 11 at the front and rear ends. Specifically, the limit rod 11 is an L-shaped angle steel, and the adjusting seat 2 is stuck between the two L-shaped angle steels.
