Technical Field

[0001] The present application relates to the technical field of foundation pit drilling, and in particular to a seismic-proof drilling device for a well track foundation pit. Background Art

[0002] Drilling in underground rail pits requires a drilling machine. A drilling machine is a general term for machinery and equipment that uses a tool harder and sharper than the target object to create a cylindrical hole or hole in the target through rotary cutting or extrusion. It is also known as a drilling rig, punching machine, eyelet drill, or through-hole machine.

[0003] The patent with the published authorization announcement number CN209654038U discloses a drilling rig comprising a frame, a base, a column mounted on the base, the column connected via a jack, a lifting frame mounted on the column, a pulley mounted on the jack, a rotating shaft mounted on the base, a rope reel mounted on the shaft, a lifting rope mounted on the rope reel, a lifting rope passing over the pulley and a hook mounted thereon, and a drilling mechanism comprising a motor and a gearbox, a belt drive between the motor and the gearbox, a hollow drill rod vertically mounted within the gearbox, the top end of the hollow drill rod connected to a water pipe via a rotary joint, and a drill bit mounted at the bottom end of the hollow drill rod; a mounting plate mounted on the frame, a lead screw mounted on the mounting plate, a movable plate mounted on the lead screw, and an arc-shaped locking plate mounted on the movable plate. The beneficial effects of this utility model are simple structure, compact size, and easy installation and disassembly.

[0031] See Figure 1 The bottom of the spiral blade 5 is fixedly connected with a pin 6, which is conical in shape, so that the pin 6 can be inserted into the soil first when drilling, thereby facilitating the spiral blade 5 to drill into the soil for drilling operations, and ensuring that the spiral blade 5 will not swing easily when it starts to contact the soil.

[0032] See Figure 2 and Figure 3 The slider 10 is slidably connected to the inner wall position of the damper 8 and the positioning bar 7. The outer diameter of the slider 10 is adapted to the inner wall diameter of the damper 8 and the positioning bar 7, so that when the spiral blade 5 is working, part of the vibration generated will be transmitted upward step by step through the spiral blade 5. When it reaches the frame 2, the damper 8 and the shock-absorbing spring 9 can achieve a double shock-absorbing effect. The damper 8 can absorb kinetic energy and reduce shock. At the same time, the rubber block 12 also has a certain shock-absorbing effect to ensure the overall stability of the frame 2.

[0033] See Figure 1 and Figure 2 Two crawlers 13 are symmetrically fixedly installed on the bottom of the platform 1, so that the device can be moved to any place of use, thereby ensuring stability during driving and being able to pass through muddy and uneven roads.

When it reaches the frame 2, the damper 8 and the shock-absorbing spring 9 can achieve a double shock-absorbing effect. The damper 8 can absorb kinetic energy and reduce shock. At the same time, the rubber block 12 also has a certain shock-absorbing effect to ensure the overall stability of the frame 2. At the same time, the hook 18 and the ring 20 can be used to connect the counterweight 19 and the wire rope 17, so as to realize the counterweight of the device and ensure that the spiral blade 5 will not easily tilt during operation. At the same time, the servo motor 15 can be driven to drive the winding wheel 16 to rotate to adjust the height of the counterweight 19, so that the height of the counterweight 19 can be adjusted according to the terrain environment, and then the weight of the counterweight can be adjusted.
