Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drilling machine fixing devices, specifically relating to a quick fixing device for lateral drilling of high-speed railway protective walls. Background Technology
[0002] The construction process standards for high-speed railway signaling engineering require that equipment in the track section within the tunnel be installed in cable troughs, such as... Figure 1 As shown, at the construction site inside the tunnel, the rail lead-out line needs to be drilled through the cable trench wall 6 (the tunnel cable trench wall is 25cm thick). The bottom of the hole is flush with the track bed surface. The cable trench wall protrudes only 30cm above the ballast surface in the tunnel. The water drill support base is only half supported by the cable trench wall, with the other half suspended and unable to be fixed. Drilling causes shaking, forcing the drill to advance slowly and resulting in misalignment, making it difficult to retrieve the drill core. Because the water drill is heavy and lacks stable support, drilling is time-consuming and laborious for operators.
[0003] Therefore, there is an urgent need for a quick-fixing device for lateral drilling of high-speed railway protective walls, which can be easily installed and fixed, and saves time and effort. Utility Model Content
[0004] The purpose of this invention is to provide a quick fixing device for lateral drilling of high-speed railway protective walls, which is suitable for drilling holes in walls where the drilling machine is inconvenient to operate in narrow spaces.

[0006] A quick fixing device for lateral drilling of a high-speed railway protective wall includes a first support frame, a second support frame arranged parallel to the first support frame, and a crossbeam that fixes the first support frame and the second support frame. A connecting plate for fixing a water drill is provided on the upper part of the second support frame. Locking mechanisms for adjusting and fixing the quick fixing device for the water drill are provided on the crossbeam and at the bottom of the first support frame.
[0007] A further improvement of the present invention is that the first support frame and the second support frame are rectangular frames, and the top ends of the second support frame and the first support frame are connected by a crossbeam.
[0008] A further improvement of the present invention is that the locking mechanism is located in the middle of the crossbeam or on the bottom frame of the first support frame. The locking mechanism includes a spiral rod passing through the crossbeam or the frame of the first support frame and a handle located on the top of the spiral rod for operating the rotation of the spiral rod. The crossbeam and the first support frame are provided with threaded holes that cooperate with the spiral rod.
[0009] A further improvement of the present invention is that the first support frame and the second support frame are composed of rods, and the crossbeam includes several crossbars connecting the first support frame and the second support frame.
[0010] A further improvement of this utility model is that: the connecting plate is provided with screw holes for fixing the water drill base, and the bottom of the screw rod of the locking mechanism on the crossbeam is provided with a tray.
[0011] A further improvement of this utility model is that the length of the first support frame is greater than that of the second support frame.
[0012] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:
[0013] This application discloses a rapid fixing device for lateral drilling of high-speed railway protective walls. The design of the first support frame, the second support frame, and the crossbeam is a contour-following design, which can be easily placed on the low wall to be drilled, such as a high-speed railway protective wall. The first support frame and the second support frame are located on both sides of the wall. A connecting plate is set on the second support frame, and the base of the drilling rig can be fixed on the connecting plate.
