Description

Technical Field

[0001] The present application relates to the technical field of water-grinding drill installation equipment, and more specifically, to a large-section hard rock tunnel water-grinding drill quick installation bracket and a use method thereof. Background Art

[0002] During the tunnel excavation process, different excavation methods are often required according to the geological conditions in the tunnel. For example, when excavating a tunnel in a large-section hard rock geology, it is often necessary to use a water-grinding drill to carry out excavation construction in order to ensure the safety of the construction.

[0003] Before the water-grinding drill is used for drilling construction, it is often necessary to fix the water-grinding drill in the required position through an installation bracket to prevent the water-grinding drill from shaking or even falling during the drilling process. Some existing installation brackets are used by drilling a small hole on the inner wall of the tunnel, and inserting an anchor rod, which is one of the components of the installation bracket, into the hole to fix the position of the installation bracket, and then the water-grinding drill is installed on the installation bracket for use. This results in low installation efficiency of the installation bracket and is inconvenient to quickly change position to continue drilling after the water-grinding drill completes the drilling operation, which needs to be improved.

[0004] In order to solve the above problems, the present application provides a large-section hard rock tunnel water-grinding drill quick installation bracket and a use method. Summary of the invention

[0006] Through the above technical solution, the threaded rod rotates to drive a sleeve rod to rotate, and the sleeve rod drives the connecting plate and the water drill located below the connecting plate to move positions, so that the water drill can be adjusted to the required position for use.

[0007] Furthermore, the translation assembly includes a slider, a mounting block is fixedly connected to the outer wall of the slider, two grooves are provided at the bottom end of the mounting block, and rotating rods are rotatably installed in the two grooves, and the bottom ends of the rotating rods are fixedly connected to rotating clamps.

[0008] Through the above technical solution, the second threaded rod is rotated to drive the slider to move in translation in the slide groove, thereby driving the water drill to adjust its position for use.

[0009] Furthermore, two connecting screws are provided between the two rotating clamps, and two threaded through holes are provided on the two rotating clamps, and the diameter of the threaded through holes on the rotating clamps is the same as the diameter of the connecting screws.

[0010] Through the above technical solution, the rotating clamp is attached to the water-grinding drill, and then the two rotating clamps are connected together by a connecting screw, so that the two rotating clamps can clamp the water-grinding drill to fix the position of the water-grinding drill.

[0011] Furthermore, the adjustment assembly includes a fixed plate, a side of the fixed plate close to the fixed frame is provided with a plurality of balance rods, a side of the fixed plate away from the balance rod is provided with a groove, and a third threaded rod is provided in the groove, a movable block is movably sleeved on the outer wall of the third threaded rod, a U-shaped block is provided on the top of the movable block, a rotating shaft is rotatably installed in the U-shaped groove on the U-shaped block, an L-shaped rotating plate is fixedly connected to the outer wall of the rotating shaft, a threaded through hole is provided on the L-shaped rotating plate, and an adjusting screw is provided in the threaded through hole, a mounting panel is rotatably connected to one side of the adjusting screw, a support plate and an arc-shaped clamping plate are provided on the side of the mounting panel away from the adjusting screw, and the arc-shaped clamping plate is located above the support plate.

[0012] Through the above technical solution, the third threaded rod is rotated to drive the movable block to move in translation, so as to adjust the position of the U-shaped block. This makes it convenient to adjust the position of the water drill on the support plate by moving the movable block in translation after the water drill is placed on the top of the support plate.

[0013] Furthermore, a threaded hole is provided on the L-shaped rotating plate, and a limiting screw is provided in the threaded hole.

[0014] Through the above technical solution, the limiting screw rotates and fits the bottom inner wall of the fixed frame and makes the bottom end of the adjusting screw contact the top of the fixed frame, which can avoid the water drill being misaligned due to the rotating shaft rotating autonomously during the operation of the water drill.

[0015] Furthermore, two translation rods are fixedly mounted on the installation panel, and the translation rods penetrate the L-shaped rotating plate and extend into the U-shaped groove on the U-shaped block.

[0016] Through the above technical solution, when the installation panel is moved by rotating the adjusting screw, the translation rod moves translationally, and the installation panel will not rotate due to the rotation of the adjusting screw to connect the installation panel.

[0020] Through the above technical solution, the positioning screw passes through the sleeve block to connect the column, so that the height of the sleeve block can be fixed by the positioning screw.

[0021] Furthermore, a plurality of threaded holes are vertically arranged on the outer wall of the column, and the diameter of the threaded holes is the same as the diameter of the positioning screw.

[0022] The above technical solution makes it easy to fix the positioning screw at different heights for use.

[0023] Furthermore, the left side wall of the threaded rod passes through the left inner wall of the translation slot and extends to the left side of the fixed frame, and a handle is fixedly installed on the left side of the threaded rod.

[0024] With the technical solution, during use, by holding the handle and controlling the rotation of the threaded rod, the sleeve rod can be driven to move in translation in the translation groove.

[0025] In summary, this application includes the following beneficial technical effects: (1) The sleeve block is adjusted to the required height on the column, and the threaded rod is controlled to rotate, which drives the connecting plate and the water-grinding drill to adjust the position in translation. Then, the second threaded rod is controlled to rotate, which drives the slider to move and adjust the position of the water-grinding drill for a second time. The water-grinding drill can be adjusted to different positions for horizontal drilling, and the water-grinding drill can be quickly set up for use and quickly changed to continue drilling after the water-grinding drill completes the drilling operation.

[0026] (2) During use, multiple sets of installation components can be added according to construction requirements to facilitate the simultaneous start of multiple sets of water-grinding drills for horizontal drilling, thereby speeding up construction efficiency.

[0027] (3) The water drill is placed on the top of the two support plates and fixed by the arc-shaped clamping plates. The third threaded rod is controlled to rotate to adjust the position of the water drill. The sleeve is controlled to move on the column to adjust the position so that the water drill fits the inner wall of the tunnel, which makes it easier to control the water drill to perform vertical drilling.

[0028] (4) Control the rotation of the two adjusting screws so that the two arc-shaped clamping plates and the two supporting plates on the two adjusting components fit together. The water drill can be removed from the rotating clamping plate on the translation component and placed on the top of the two supporting plates and clamped and fixed by the arc-shaped clamping plates. Through simple disassembly and installation, the horizontal drilling and vertical drilling brackets can be quickly converted, which can improve the overall applicability and save installation time and cost.
