The technical scheme of the invention is as follows:
the utility model provides a down-the-hole drill mount for anchor rope drilling construction which characterized in that: the device comprises a support, wherein the support comprises a horizontally arranged rectangular base, two front supporting legs and two rear supporting legs are respectively welded at the front end and the rear end of the base, the rear supporting legs are higher than the front supporting legs, a horizontal front cross rod is connected between the upper ends of the two front supporting legs, a horizontal rear cross rod is welded between the upper ends of the two rear supporting legs, a guide rail is welded between the front cross rod and the rear cross rod, a limiting plate is welded at the rear end of the guide rail along the cross section of the guide rail, a down-the-hole drill is arranged on the top surface of the guide rail, a drill bit of the down-the-hole drill faces the front end of the guide rail, an advancing and retreating rod is respectively arranged along two sides of the guide rail, the two advancing and retreating rods are movably inserted on the limiting plate, a limiting nut is screwed at the outer side of the limiting plate at the rear end of each advancing and retreating rod, a connecting rod perpendicular to the advancing and retreating rod is, and the inner side edges of the two connecting plates are respectively close to the upper edges of the two sides of the guide rail.
The utility model discloses fix the down-the-hole drill on the support, by support regulation drilling angle, displacement about advance and retreat pole and deflector restriction down-the-hole drill has effectively solved the manual work and has mastered and adjust the drilling accuracy not enough difficult problem that arouses to the down-the-hole drill, has improved the accuracy of anchor rope drilling, guarantees constructor's personal safety, has improved the efficiency of construction.
Drawings
Fig. 1 is a schematic side view of the present invention;
fig. 2 is a schematic cross-sectional structure of the present invention.
Detailed Description
As shown in figure 1, the utility model comprises a support, the support comprises a rectangular base 1 which is horizontally arranged, the front end and the rear end of the base are respectively welded with two front support legs 2 and two rear support legs 3, the height of the rear support leg 3 is higher than that of the front support leg 2, a horizontal front cross rod 4 is connected between the upper ends of the two front support legs 2, a horizontal rear cross rod 5 is welded between the upper ends of the two rear support legs 3, a guide rail 6 is welded between the front cross rod 4 and the rear cross rod 5, the rear end of the guide rail 6 is welded with a limit plate 7 along the cross section of the guide rail, the top surface of the guide rail 6 is provided with a down-the drill 8, the drill bit of the down-the-guide rail 6 is towards, a connecting plate 12 is welded at the upper end of the connecting rod 11, the connecting plate 12 is fixedly connected with a bottom plate 13 of the down-the-hole drill 8 through a bolt 14, and the inner side edges of the two connecting plates 12 are respectively close to the upper edges of the two sides of the guide rail 6.
As shown in fig. 2, the cross section of the guide rail 6 of the present invention is i-shaped. During specific implementation, the guide rail 6 can adopt two channel steels, waist plates of the two channel steels are oppositely arranged left and right, leg plates at the bottoms of the two channel steels are welded with a front cross rod 4 and a rear cross rod 5 of the support, and a bottom plate 13 of the down-the-hole drill 8 is supported on the leg plates at the tops of the two channel steels. The guide rail 6 can also be made of I-steel, the lower flange plate of the I-steel is welded with the front cross rod and the rear cross rod of the bracket, and the bottom plate of the down-the-hole drill is supported on the upper flange plate of the I-steel.
In order to prevent the drill rod of the down-the-hole drill from shaking too much in the drilling process and ensure the construction safety, a guide plate 15 parallel to the cross section of the guide rail can be welded at the top of the front end of the guide rail 6, and a guide hole for the down-the-hole drill to pass through is arranged in the middle of the guide plate.
The utility model discloses during operation, the support supports subaerial, aligns the design drilling position on the rock mass with the drill bit of down-the-hole drill, can set up the inclination of backing plate adjustment support on ground according to drilling angle, starts the down-the-hole drill, and the drill bit passes by the guiding hole on the deflector and begins drilling, creeps into the in-process, and down-the-hole drill and advance and retreat the pole and slide forward along the guide rail, and the connecting plate of advance and retreat pole front end is pressed close to in the guide rail both sides, controls about the restriction down-the-hole drill.
