Description

Technical Field

[0001] This utility model belongs to the field of blasting engineering technology, specifically relating to a drilling machine for blasting engineering with controllable depth. Background Technology

[0002] A drilling machine for blasting engineering is a device specifically designed for drilling in underground blasting operations. Its main purpose is to create holes in materials such as rock, soil, or concrete to facilitate blasting operations. Depending on different needs and operating environments, blasting drilling machines can be divided into various types, which must be determined based on specific engineering requirements and environmental conditions to ensure operational efficiency and safety.

[0003] In some existing drilling machines used in blasting projects, when the drill rod is held by the operator during drilling operations, the exposed part of the drill rod after it has entered the rock mass often lacks an effective length marking device. This makes it difficult for the operator to intuitively and accurately judge the current insertion depth of the drill rod, which in turn affects the precise control and fine-tuning of the hole depth. This not only reduces the accuracy of drilling operations but also increases the construction difficulty and operational inconvenience. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a controllable-depth drilling machine for blasting engineering. This addresses the issue mentioned in the background art where, during drilling operations, some existing drilling machines for blasting engineering, once the drill rod is partially submerged in the rock mass, often lack an effective length marking device for the exposed portion. This makes it difficult for operators to intuitively and accurately judge the current insertion depth of the drill rod, thus affecting the precise control and fine-tuning of the hole depth. This not only reduces the accuracy of drilling operations but also increases construction difficulty and operational inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for blasting engineering with controllable depth, comprising a main body mechanism and a marking mechanism disposed on the outside of the main body mechanism. The marking mechanism includes a collar fixedly connected to the outside of a cylinder body. A first base plate is fixedly connected to the outside of the collar. Several first base plates are symmetrically arranged. A damping pad is fixedly connected to the inside of the first base plate. A screw is movably connected to the inside of the damping pad. A limit ring is fixedly connected to the outside of one end of the screw. A rotating ring is threadedly connected to the outside of the screw. The rotating ring is located on one side of the first base plate. A spring is disposed between the limit ring and the rotating ring. A screw is movably connected to the inside of the spring. A second base plate is fixedly connected to the other end of the screw. An outer ring is fixedly connected to one side of the second base plate. A sliding frame is fixedly connected to one side of one of the second base plates. A first base plate is slidably connected to the outside of the sliding frame. A scale is fixedly connected to the inside of the sliding frame.

[0006] Preferably, the output end of the cylinder is fixedly connected to a connecting end, the outer side of the cylinder is fixedly connected to an outer frame, and a handle is fixedly connected to one side of the outer frame.

[0007] Preferably, an anti-slip pad is fixedly connected to one side of the outer ring.

[0008] Preferably, each of the first substrate and the second substrate is fixedly connected with a reinforcing rib, and a plurality of the reinforcing ribs are symmetrically arranged.

[0009] Preferably, a pinch pad is fixedly connected to the outer side of the rotating ring, and the outer surface of the pinch pad is symmetrically provided with several grooves.

[0010] Preferably, a slide bar is fixedly connected to one side of the slide frame. The slide bar has a T-shaped structure, and a first substrate is slidably connected to the outside of the slide bar.

[0011] Preferably, a reflective sticker is fixedly connected to the other side of the sliding frame, and the reflective sticker is located outside the scale.

[0012] Preferably, the damping pad is made of rubber, and a first substrate is fixedly connected to the outside of the damping pad.

[0013] Compared with the prior art, this utility model provides a drilling machine for blasting engineering with controllable depth, which has the following beneficial effects:

[0014] 1. This utility model connects the drill rod to the connecting end by setting a scale. Then, each rotating ring is rotated counterclockwise on the outside of the screw, moving the rotating ring away from the first base plate. Each screw then slides within the damping pad of the first base plate, causing the outer ring to move until the anti-slip pad and the tip of the drill rod are at the same horizontal level. The position of the outer ring and the anti-slip pad is then corrected. At this point, the rotating ring is rotated in the opposite direction, moving it to a position where one side of the rotating ring contacts the first base plate, preventing the screw from moving towards the rock wall. Simultaneously, the friction between the rubber damping pad and the screw ensures that the screw can stably maintain its position relative to the current rotary table when not under pressure. Finally, after holding the main body mechanism, the drill rod installed at the output end of the main body mechanism is pressed against the rock wall. At this time, the tip of the drill rod and the anti-slip pad on the outer ring side are in contact with the rock wall. Open the cylinder to drive the drill rod on the connecting end side to start drilling. Hold the handle and apply a pushing force towards the rock wall so that the drill rod gradually enters the rock wall. As the main body mechanism moves, since the outer ring and the anti-slip pad on its side are squeezed by the rock wall, the screw and the scale in the slide frame begin to slide at a uniform speed in the first base plate. According to the length information marked by the scale that has moved out, the operator can accurately control the depth of the drill rod in the rock wall, thereby completing the fine adjustment of the drilling depth and reducing the construction difficulty.

[0015] 2. By setting reinforcing ribs, this utility model can effectively ensure the stability of the first substrate and the second substrate structure;

[0016] 3. By setting a pinch pad, this utility model can effectively and conveniently allow personnel to directly pinch and rotate the ring on the outer wall of the screw.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a controllable depth drilling machine for blasting engineering, including a main body mechanism 1 and an marking mechanism 2 disposed on the outside of the main body mechanism 1. The marking mechanism 2 includes a collar 201 fixedly connected to the outside of a cylinder 101. A first substrate 202 is fixedly connected to the outside of the collar 201. Several first substrates 202 are symmetrically arranged. A damping pad 203 is fixedly connected to the inside of the first substrate 202. A screw 204 is movably connected to the inside of the damping pad 203. A limit ring 205 is fixedly connected to the outside of one end of the screw 204. A rotating ring 206 is threadedly connected to the outside of the screw 204. The rotating ring 206 is located on one side of the first substrate 202. A spring 207 is provided between the limiting ring 205 and the rotating ring 206. A screw 204 is movably connected to the inner side of the spring 207. A second base plate 209 is fixedly connected to the other end of the screw 204. An outer ring 208 is fixedly connected to one side of the second base plate 209. A sliding frame 210 is fixedly connected to one side of one of the second base plates 209. A first base plate 202 is slidably connected to the outer side of the sliding frame 210. A scale 211 is fixedly connected to the inner side of the sliding frame 210. The drill rod is connected to the connecting end 103. Then, each rotating ring 206 is rotated counterclockwise outside the screw 204, so that the rotating ring 206 moves away from the first base plate 202. Then, the damping pad 203 of the first base plate 202... The internal sliding screws 204 drive the outer ring 208 to move until the anti-slip pad 3 and the drill rod tip are on the same horizontal line. The positions of the outer ring 208 and the anti-slip pad 3 are then corrected. At this time, the rotating ring 206 is rotated in the opposite direction to move it to the position where it contacts the first substrate 202 on one side of the rotating ring 206, so that the screw 204 has no ability to move towards the rock wall. At the same time, the friction between the rubber damping pad 203 and the screw 204 ensures that the screw 204 can remain stable with the current turntable when it is not under pressure. Finally, after holding the main body mechanism 1, the drill rod attached to the output end of the main body mechanism 1 is pressed against the rock wall. At this point, the tip of the drill rod and the anti-slip pad 3 on one side of the outer ring 208 are in contact with the rock wall. The cylinder 101 is opened, which drives the drill rod on one side of the connecting end 103 to start drilling. The handle 104 is held and pushed towards the rock wall, so that the drill rod gradually enters the rock wall. As the main body mechanism 1 moves, since the outer ring 208 and the anti-slip pad 3 on one side are squeezed by the rock wall, the screw 204 and the scale 211 in the slide frame 210 begin to slide at a constant speed in the first base plate 202. According to the length information marked by the scale 211, the operator can accurately control the depth of the drill rod in the rock wall, thereby completing the fine adjustment of the drilling depth and reducing the construction difficulty.

[0026] In this utility model, preferably, the output end of the cylinder 101 is fixedly connected to the connecting end 103, the outer frame 102 is fixedly connected to the outer side of the cylinder 101, and the handle 104 is fixedly connected to one side of the outer frame 102. The drill rod is connected to the connecting end 103, and the cylinder 101 is opened to drive the drill rod to work after holding the handle 104.

[0027] In this invention, preferably, an anti-slip pad 3 is fixedly connected to one side of the outer ring 208, which can effectively improve the stability of the device when it is pressed against the rock wall.

[0028] In this utility model, preferably, each of the first substrate 202 and the second substrate 209 is fixedly connected with a reinforcing rib 4, and a plurality of reinforcing ribs 4 are symmetrically arranged, which can effectively ensure the stability of the structure of the first substrate 202 and the second substrate 209.

[0029] In this utility model, preferably, a pinch pad 5 is fixedly connected to the outer side of the rotating ring 206. Several grooves are symmetrically arranged on the outer surface of the pinch pad 5, which can effectively facilitate personnel to directly pinch and rotate the rotating ring 206 on the outer wall of the screw 204.

[0030] In this utility model, preferably, a slider 6 is fixedly connected to one side of the slider frame 210. The slider 6 has a T-shaped structure, and a first substrate 202 is slidably connected to the outside of the slider 6, which can effectively ensure the stability of the position of the slider frame 210 during the sliding process.

[0031] In this utility model, preferably, a reflective sticker 7 is fixedly connected to the other side of the sliding frame 210. The reflective sticker 7 is located outside the scale 211 and can mark the position of the sliding frame 210 in a relatively dim environment.

[0032] In this utility model, preferably, the damping pad 203 is made of rubber, and the first substrate 202 is fixedly connected to the outside of the damping pad 203. It has a certain expansion and contraction capacity, which can effectively limit the position of the screw 204 to keep it stable, while not affecting the sliding ability of the screw 204 after being squeezed.

[0033] The working principle and usage process of this utility model are as follows: In use, the drill rod is connected to the connecting end 103. Then, each rotating ring 206 is rotated counterclockwise on the outside of the screw 204, moving the rotating ring 206 away from the first substrate 202. Next, each screw 204 slides within the damping pad 203 of the first substrate 202, causing the outer ring 208 to move until the anti-slip pad 3 and the drill rod tip are at the same horizontal level. The positions of the outer ring 208 and the anti-slip pad 3 are then corrected. At this point, the rotating ring 206 is rotated in the opposite direction, moving it to a position where it contacts the first substrate 202 on one side of the rotating ring 206. This prevents the screw 204 from moving towards the rock wall. Simultaneously, the friction between the rubber damping pad 203 and the screw 204 ensures that the screw 204 is not subjected to pressure. When the main body mechanism 1 is in a stable position, the drill rod attached to the output end of the main body mechanism 1 is pressed against the rock wall. At this time, the tip of the drill rod and the anti-slip pad 3 on the side of the outer ring 208 are in contact with the rock wall. The cylinder 101 is opened to drive the drill rod on the side of the connecting end 103 to start drilling. The handle 104 is held and pushed towards the rock wall, so that the drill rod gradually enters the rock wall. As the main body mechanism 1 moves, the outer ring 208 and the anti-slip pad 3 on its side are squeezed by the rock wall. Therefore, the screw 204 and the scale 211 in the slide frame 210 begin to slide at a uniform speed in the first base plate 202. According to the length information marked by the scale 211, the operator can accurately control the depth of the drill rod in the rock wall, thereby completing the fine adjustment of the drilling depth and reducing the construction difficulty.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
