By adopting the bracket, no ladder is needed for climbing operation, so that independent operation of one person can be realized, and the safety problems that the drilling dust or particles enter eyes of an operator and the like are avoided because the operator is far away from the percussion drill. Not only improves the drilling operation efficiency of the top plate, but also ensures the operation safety.
Description
Technical Field
The utility model relates to a percussion drill support, in particular to a downhole top plate percussion drill support.
Background
In mine down-hole operations, it is often necessary to drill holes in the roof of a roadway or work surface using a pilot drill for securing and installing the corresponding equipment. Because of the lack of a convenient bracket device at present, the drilling operation needs at least two persons to work cooperatively, one person supports the ladder, and the other person climbs the ladder to perform the drilling operation. Not only the operation efficiency is lower, but also there is the safety risk that dust or particles generated by the dumping and punching of the ladder enter eyes of operators and the like.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a downhole roof impact drill support, which is used for realizing that a person operates to finish roof drilling and eliminating construction potential safety hazards.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the underground top plate impact drill support is characterized by comprising a support rod and a feed rod which are arranged in parallel, and further comprising a connecting rod with two ends respectively hinged to the support rod and the feed rod and a lever positioned below the connecting rod; one end of the lever is hinged with the feed rod, and the other end of the lever is connected with a treading driving mechanism through a connecting rope; the lever is also hinged with the supporting rod; the feeding rod is fixedly provided with a support for installing the impact drill and a stop lever for hanging a pull ring serving as an impact drill switch operating mechanism.
Preferably, the treading driving mechanism comprises a pedal and at least two inclined rods which are positioned on the upper side of the pedal and fixed on the pedal, wherein the lower ends of the inclined rods are fixed on the pedal, the upper ends of the inclined rods are connected with each other and connected with the lower end of the connecting rope in parallel; a gap penetrating into the foot of an operator is arranged between the adjacent diagonal rods.
Preferably, the lower side of the stop lever is provided with a concave cambered surface.
The utility model has the positive effects that:
the utility model uses lever principle, uses pedal to press the free end of lever, to make the impact drill receive upward thrust, to complete drilling operation. By adopting the bracket, no ladder is needed for climbing operation, so that independent operation of one person can be realized, and the safety problems that the drilling dust or particles enter eyes of an operator and the like are avoided because the operator is far away from the percussion drill. Not only improves the drilling operation efficiency of the top plate, but also ensures the operation safety.
When the top plate is drilled, the drilling head is ensured to move vertically upwards all the time by means of the four-bar linkage mechanism, and the requirement of underground conventional shallow hole operation can be met.
The support can be formed by assembling and welding steel pipes, and has the characteristics of light weight, portability, labor saving in drilling operation of the top plate and the like.

Detailed Description
The utility model is further described below with reference to the drawings and examples.
As shown in fig. 1, the underground top plate impact drill support of the present embodiment includes a support rod 1 and a feed rod 4 which are vertically arranged and parallel to each other, a connecting rod 3 with left and right ends respectively hinged to the support rod 1 and the feed rod 4, and a lever 2 positioned below the connecting rod 3, wherein one end (i.e., the right end in fig. 1) of the lever 2 is hinged to the feed rod 4, the hinge point is usually positioned at the lower end of the feed rod 4, the other end (i.e., the left end in fig. 1) is used as a free end, and a pedal driving mechanism 9 is connected to the lever 2 through a connecting rope, and the hinge point is usually positioned in the middle of the lever 2.
The pedal driving mechanism 9 generally comprises a pedal and at least two inclined rods which are positioned on the upper side of the pedal and fixed on the pedal, wherein the lower ends of the inclined rods are welded on the upper side surface of the pedal, the upper ends of the inclined rods are mutually welded and connected with the lower ends of the connecting ropes. A gap penetrating into the foot of an operator is arranged between the adjacent diagonal rods.
The feeding rod 4 is fixedly provided with a support 6 for seating and installing the impact drill 5, the impact drill 5 is connected with a pull ring 7 serving as a switch operating mechanism through an elastic pull rope, and the feeding rod 4 is fixedly provided with a stop lever 8 for hanging the pull ring 7. The switch operating process comprises the following steps: when the pull rope is pulled downwards through the pull ring 7, the percussion drill 5 starts to operate, and when the pull rope is loosened, the percussion drill 5 stops. In order to prevent the pull ring 7 from falling off the stop lever 8 in a vibration state, the lower side of the stop lever 8 is processed into a concave cambered surface 8-1. When the pull ring is hung on the stop lever 8, the pull ring 7 is clamped at the highest position where the center of the concave cambered surface 8-1 contacts with the stop lever 8.
In use, an operator places the hammer drill 5 on the support 6 and positions the drill body of the hammer drill against the side of the feed rod 4, securing the hammer drill 5 and the feed rod 4 together with a tie. The bottom of the supporting rod 1 is placed on the ground, and when the top plate is too high, the bottom of the supporting rod 1 is placed on the cushion block. Pulling the pull ring 7 starts the percussion drill 5, and hanging the pull ring 7 on the stop lever 8, the continuous work of the drilling machine can be kept, and the pedal of the driving mechanism 9 is stepped down by feet, so that the drilling machine performs the drilling operation vertically upwards.
After the drilling is finished, the pedal is loosened, the pull ring 7 is removed from the stop lever 8, the impact drill is stopped, and the drilling is finished. The whole operation process only needs about 5 minutes.
The impact drill according to the embodiment of the present utility model is typically a battery type impact drill.
