Description

Technical Field

[0001] This utility model relates to the technical field of drilling devices, and in particular to a tunnel fracture drilling device. Background Technology

[0002] my country's complex and diverse topography and landforms mean that tunnel construction is constrained by various complex natural conditions, including geological conditions and geographical environment. Furthermore, improper selection of waterproofing materials, inadequate treatment of construction joints, and subsequent aging of the tunnel structure can all lead to water seepage through tunnel fissures, threatening the stability and service life of the tunnel structure and seriously endangering people's lives and property. When treating tunnel fissures, drilling is required at the fissures. Grouting holes are arranged according to the width and depth of the cracks at the seepage point. Drilling machines are used to drill holes at predetermined locations, and the drilling depth should ideally reach the seepage point. However, currently, drilling during construction is mostly done manually, making it difficult to control the drilling depth. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of existing technologies where it is difficult to control the drilling depth through manual drilling, and provides a tunnel fissure drilling device that can drill to a specified depth after positioning.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tunnel fracture drilling device, comprising: Installation plate, on which a positioning rod is installed; A fastening assembly, wherein the fastening assembly is mounted on a positioning rod; A lifting frame, wherein the lifting frame is mounted on a mounting plate; A drilling machine, wherein the drilling machine is mounted on a lifting frame and is slidably connected to the lifting frame.

[0005] The mounting plate is positioned by a positioning rod, and then the mounting plate is fixed to the surface of the tunnel wall by a fastening component on the positioning rod. This aligns the drilling machine mounted on the mounting plate with the crack. The drilling machine is then driven by a lifting frame to drill a hole in the crack, forming a grouting hole. The drilling machine can drill to a specified depth after positioning, achieving the goal of drilling to a specified depth.

[0006] Preferably, the positioning rods are provided in a plurality of circularly distributed positions, and a positioning block is installed at the lower end of each positioning rod. The positioning block has a triangular cross-sectional shape. The circularly distributed positioning rods can ensure the stability of the positioning plate and facilitate the operation of the drilling machine on the positioning plate. Before drilling, positioning holes need to be drilled in the wall. After the lower end of the drilling machine is aligned with the crack, the positioning point is nailed by the contact between the positioning block at the lower end of the positioning rod and the wall. Then, a positioning hole is drilled at the positioning point. The lower end of the positioning rod and the positioning block are then placed in the positioning hole. The conical positioning block can better perform positioning. This design facilitates positioning.

[0007] Preferably, the positioning rod has a threaded hole, and the fastening assembly includes a sliding block and a screw. The sliding block is placed inside the threaded hole, and there are two sliding blocks, which are respectively placed on both sides of the threaded hole. The positioning rod has a telescopic hole, which corresponds to the sliding block. The bottom surface of the threaded hole has a sliding groove, and a sliding block is installed on the bottom surface of the sliding block. The sliding block is slidably connected to the positioning rod through the cooperation of the sliding block and the sliding groove. The lower end of the screw is placed inside the threaded hole and connected to the threaded hole. A pressing block is installed on the bottom surface of the screw. The sliding block has a pressing slope on the side facing the pressing block, and the pressing block matches the pressing slope. The positioning rod has a threaded hole that opens at the top of the mounting plate. A sliding groove is provided on the bottom surface of the threaded hole. The sliding blocks of the two fastening components are placed on the bottom surface of the threaded hole. The two sliding blocks are respectively placed on both sides of the threaded hole and correspond to the telescopic holes on both sides. The sliding blocks are connected to the threaded hole by the screw rod through the cooperation between the sliding block and the sliding groove. The screw rod is rotated to drive the extrusion block to move down. The moving extrusion block continuously extrudes the extrusion slope of the sliding block, causing the sliding block to move towards the telescopic hole. One end of the sliding block extends out of the telescopic hole and then extends to the side of the extrusion positioning hole, fixing the positioning rod in the positioning hole. This design can fix the positioning rod.

[0008] Preferably, the sliding block is equipped with a spring, with both ends of the spring connected to the sliding blocks on both sides respectively. A fitting block is provided on the side of the sliding block facing the telescopic hole, with one end connected to the sliding block and the other end placed inside the telescopic hole. A screwing block is installed at the upper end of the screw. To achieve the reset of the sliding block after contact fixing, a spring is installed between the two sliding blocks. The spring can pull the sliding block back to its original position. Simultaneously, to better compress the inner wall of the positioning hole, a fitting block is installed on the sliding block. The fitting block is made of a material with a certain degree of elasticity. After the sliding block pushes the fitting block out of the telescopic hole and fits against the positioning hole, it can better compress the inner wall of the positioning hole. At the same time, a screwing block is installed at the top of the screw, which drives the screw to rotate. This design facilitates the compression of the inner wall of the positioning hole.

[0009] Preferably, the mounting plate has through holes. The lifting frame includes a top plate, guide rods, and a bottom plate. Several guide rods are arranged circumferentially. One end of each guide rod is connected to the top plate, and the other end passes through the mounting plate and is positioned on the other side of the mounting plate. The end of the guide rod passing through the mounting plate is connected to the bottom plate, which is connected to the mounting plate. A drop hole is installed on the bottom plate, corresponding to the through holes. The mounting plate has through holes for working on the wall below it. Several guide rods are circumferentially distributed along the axis of the through holes. The guide rods pass through the mounting plate, with the top plate installed at the upper end and the bottom plate installed at the lower end. The bottom plate is fixedly connected to the mounting plate, and a drop hole corresponding to the through hole is opened on the bottom plate. This design allows for the treatment of cracks through the mounting plate.

[0010] Preferably, a pneumatic cylinder is installed on the top plate, and a lifting plate is installed on the top surface of the drilling machine. The lifting plate has lifting holes, and the lifting plate is slidably connected to the guide rod through the lifting holes. The pneumatic end of the pneumatic cylinder is connected to the lifting plate, and the lower end of the drilling machine corresponds to the through hole. The pneumatic cylinder installed on the top plate can drive the drilling machine on the lifting plate to move up and down. The lifting plate can only move up and down along the lifting rod due to the restriction of the lifting holes, ensuring the stability of the drilling machine during movement. The pneumatic cylinder can control the drilling machine to descend a specified distance by moving the lifting plate along the guide rod, and then drill a hole in the crack after passing through the through hole. This design allows for control of the descent distance, as the drilling machine is a machine used for drilling in the prior art.

[0011] The advantages of this utility model are: it can drill to a specified depth after positioning, which is convenient for positioning; it can fix the positioning rod, which is convenient for squeezing the inner wall of the positioning hole; it can pass through the mounting plate to treat the cracks; and it can control the descent distance.
