Description
Technical Field
[0001] This utility model relates to the field of static blasting technology, specifically to a static blasting fixed-depth drilling device. Background Technology
[0002] In the construction of underground utility tunnels, it is often necessary to break up the rock strata along the route to ensure the smooth construction of the main structure of the tunnel. Since underground utility tunnels are mostly located in or around urban built-up areas, traditional blasting operations are prone to generating strong vibrations, noise and flying rocks, which not only pose safety hazards to surrounding buildings and underground pipelines, but may also cause environmental nuisance. Therefore, static blasting technology has become the preferred solution for breaking up rock strata in underground utility tunnels.
[0003] Static blasting technology involves drilling holes in rock strata, filling the holes with a static fracturing agent, and utilizing the expansion pressure generated by the hydration reaction of the agent to crack and break the rock strata. During drilling operations, the drilling depth directly determines the effectiveness of static blasting: if the drilling depth is too shallow, the rock strata may not be completely cracked, requiring secondary drilling and blasting, increasing construction costs and time; if the drilling depth is too deep, it may penetrate underground pipelines or foundation structures beneath the rock strata, causing safety accidents such as pipeline leaks and structural damage. Furthermore, drilling operations generate dust problems. This dust, mainly composed of rock debris and ash, not only directly pollutes the construction site environment but also poses potential health hazards to construction workers.
[0004] Therefore, based on the above problems, a static blasting fixed-depth drilling device is proposed. Utility Model Content

Detailed Implementation
[0017] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0018] Embodiment 1 of this utility model: as follows Figures 1-3As shown, this embodiment provides a static blasting depth drilling device, including a mobile vehicle 1. The mobile vehicle 1 is equipped with a control cabinet for controlling the operation of the electrical equipment of this utility model. The top of the mobile vehicle 1 is provided with a linear module 3, also known as a linear module, linear slide, or linear slide table. It is a mechanical component in the field of industrial automation that realizes linear reciprocating motion and is widely used in scenarios that require high-precision positioning, repetitive motion, or automated conveying.
[0019] The linear module 3 is provided with a drilling assembly 4 on one side. Specifically, the drilling assembly 4 includes a platform 41. The top of the platform 41 is provided with a motor cover 42. A drill rod 43 is rotatably provided at one end of the motor cover 42. A motor for driving the drill rod 43 to rotate is fixed inside the motor cover 42. A slide plate 44 is fixed at the bottom of the motor cover 42. The slide plate 44 is slidably connected to the top of the platform 41 through a slide rail. A hydraulic cylinder 45 for driving the slide plate 44 to move is fixed at the top of the platform 41 to drive the drill rod 43 to move.
[0020] The mobile vehicle 1 is equipped with a collection component 2 at its top. The collection component 2 includes a collection box 21. The linear module 3 is fixed to the top of the collection box 21. The platform 41 is rotatably equipped with a mounting seat 7 on the side near the linear module 3. The mounting seat 7 is fixed on the linear module 3. An electric push rod 8 is provided between the top of the collection box 21 and the bottom of the platform 41. The two ends of the electric push rod 8 are rotatably connected to the platform 41 and the collection box 21, respectively.
[0021] During drilling operations, the present invention is first moved to the position where drilling is required, then the moving vehicle 1 is stopped and locked. Then, the platform 41 is driven to rotate by the electric push rod 8 to adjust the angle of the drill rod 43 so as to adjust the drilling angle. Then, the motor is started to drive the drill rod 43 to rotate, and at the same time, the hydraulic cylinder 45 is started to drive the slide plate 44 forward, thereby driving the motor cover 42 and the drill rod 43 forward to drill. This embodiment realizes convenient adjustment of the angle of the drill rod 43, adapts to the multi-angle drilling needs in different scenarios, and expands the application range of this device.
[0022] Embodiment 2 of this utility model: as follows Figures 1-3 As shown, a limiting component 6 is provided on the top of the drilling assembly 4 for static blasting depth drilling operations; specifically, the limiting component 6 includes a fixing pipe 61, which is fixed to the top of the platform 41 near the straight module 3 by a connecting block 62, and a slip ring 63 slides on the outer wall of the fixing pipe 61, and the slip ring 63 is fixed to the fixing pipe 61 by a locking bolt.
[0023] A slider 64 is fixed to the top of the motor cover 42. The slider 64 is sleeved on the outer wall of the fixed tube 61 and slidably connected to the fixed tube 61.
[0024] The outer wall of the connecting block 62 is machined with scale lines to indicate the distance between the slider 64 and the slip ring 63, i.e., the drilling depth.
[0025] Before drilling, loosen the locking bolt on the slip ring 63, and then slide the slip ring 63 along the fixed pipe 61 to adjust the distance between the slip ring 63 and the slider 64. This distance is the drilling depth. Then tighten the locking bolt. During drilling, the slider 64 moves forward with the motor cover 42 and the drill rod 43. When the slider 64 moves to contact the slip ring 63, it stops. At this time, the motor cover 42 and the drill rod 43 no longer move forward, which makes it easier to control the drilling depth. This achieves fixed-depth drilling, which not only ensures the integrity and efficiency of rock blasting and avoids the cost accumulation of secondary construction, but also provides reliable depth protection for underground concealed facilities and foundation structures, significantly reducing construction safety risks and accidental losses.
[0026] Embodiment 3 of this utility model: as follows Figures 1-6 As shown, a dust collection component 5 is provided on the side of the drilling assembly 4 away from the linear module 3, which is used to handle the debris and dust generated during drilling operations. Specifically, the dust collection component 5 includes a hollow ring 51, the space in the middle of the hollow ring 51 is convenient for the drill rod 43 to pass through, the end of the fixing tube 61 near the hollow ring 51 is fixed to the top of the hollow ring 51, the bottom of the hollow ring 51 is fixed with a collection box 52 for collecting debris, and a plurality of suction holes 55 for absorbing dust are opened on the inner side of the hollow ring 51.
[0027] The hollow ring 51 is located at the end of the drill rod 43 away from the motor cover 42. The inner cavity of the hollow ring 51 is divided into cavity one 53 and cavity two 54 by two partitions. Multiple suction holes 55 are connected to cavity one 53. Cavity one 53 has a through-hole 56 at both the top and bottom. The top of the collection box 52 has a through-hole 57. Cavity two 54 is connected to the inside of the collection box 52 through through-hole one 56 and through-hole two 57. The side of the collection box 52 closest to the motor cover 42 is fixed to the platform 41. The bottom of the collection box 52 is open, and a cover plate 58 is hinged to the bottom of the collection box 52.
[0028] A filter screen 22 is fixed inside the collection box 21, which divides the inside of the collection box 21 into a collection chamber 23 and an installation chamber 24 distributed vertically. A suction pipe 27 is fixed between one side of the top of the collection box 21 and the end of the fixed pipe 61 away from the hollow ring 51. The hollow chamber 53, the fixed pipe 61, the suction pipe 27 and the collection chamber 23 are connected in sequence. An air outlet pipe 28 is fixedly connected to the other side of the top of the collection box 21. One-way valves are fixed on both the suction pipe 27 and the air outlet pipe 28. The one-way valve on the suction pipe 27 only allows the medium in the suction pipe 27 to enter the collection chamber 23, and the one-way valve on the air outlet pipe 28 only allows the medium in the collection chamber 23 to be discharged through the air outlet pipe 28.

[0030] During drilling, the end of the dust collection component 5 furthest from the drilling component 4 is attached to the drilling surface. The drill rod 43 passes through the space in the middle of cavity 53 and drills into the drilling surface. Heavier rock debris discharged from the drilled hole falls and is collected in collection box 52 through opening 56, cavity 54, and opening 57. Simultaneously, the suction fan 25 starts, and lighter dust and other impurities in the hole are sucked into cavity 53 through suction hole 55. The dust then enters collection chamber 23 along fixed pipe 61 and suction pipe 27. After drilling is completed, opening cover 58 facilitates cleaning the inside of collection box 52, and opening box cover 29 facilitates cleaning the inside of collection box 21. This embodiment facilitates the collection of rock debris, dust, and other impurities generated during drilling, not only maintaining a clean and orderly construction site and reducing the workload and cost of subsequent cleaning, but also effectively reducing the health hazards to construction workers.
