Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1, a safe drilling device for track construction, including support frame 1, clamp bolt 2, nut adjusting device 3, piston rod 4, energy storage spring 5, spring cylinder 6, drill bit sleeve 7, ratchet wrench 8, drill bit 9 and track 10, support frame 1 includes upper portion and lower part, form by two different thickness's steel sheet welding, clamp bolt 2 lower part passes the steel sheet on support frame 1 upper portion and is connected with piston rod 4 upper end, nut adjusting device 3 installs on the steel sheet right side on support frame 1 upper portion, piston rod 4 lower extreme and energy storage spring 5 fix in spring cylinder 6, drill bit sleeve 7 upper end connection spring cylinder 6, drill bit 9 is connected to the lower extreme, ratchet wrench 8 installs on drill bit sleeve 7 right side, drill bit 9 front end contacts on track 10 surfaces.
The lower part of the support frame is a steel plate, the bottom of the steel plate is bent into a hook shape, the upper part of the support frame is also a steel plate, and the upper steel plate and the lower steel plate are vertically connected.
The left side and the right side of the inner wall of the spring cylinder body are respectively milled with a vertical groove.
The drill sleeve is used for clamping the drill and is connected with the spring cylinder.
The using method comprises the following steps: firstly, a hook head of a support frame of a track drilling machine is used for clamping a track, a drill bit is selected, and then all parts are installed according to requirements. Adjusting the nut adjusting device to enable the drill bit to be aligned to the track drilling position. And the compression bolt is screwed to enable the energy storage spring to store energy. The energy storage spring extends along with the increase of the depth of the drilling hole, so that the compression bolt is prevented from being fastened all the time in the drilling process. The ratchet wrench is continuously rotated to rapidly drill the track. And after the drilling is finished, the compression bolt is retreated to the initial position, and the drilling machine is taken down. If drilling is continued, the machine does not need to be disassembled, the next drilling position of the track is directly lifted, and the drilling can be carried out after the compression bolt is screwed.
Round holes with the depth of 20mm are formed in the bottoms of the compression bolts and are in clearance fit with the upper ends of the piston rods. The piston rod and the energy storage spring are fixed in the spring barrel. In order to prevent the energy storage spring from being damaged due to the rotation of the spring cylinder during the drilling operation, vertical grooves are respectively milled on the left side and the right side of the inner wall of the spring cylinder, and the piston is designed into a corresponding shape, so that the piston can only move up and down in the spring cylinder, and the energy storage spring is prevented from being damaged due to torsion.
The upper part and the lower part of the support frame are formed by welding two steel plates with different thicknesses. The bottom of the steel plate at the lower part of the support frame is bent into a hook shape so as to clamp the track during drilling operation; the upper steel plate of the support frame is large in thickness, the middle milling groove is formed, and the nut adjusting device is installed, so that the compression bolt can move in the horizontal direction, the drilling position can be adjusted, and the purpose of drilling different types of tracks is achieved.
