Description

Technical Field

[0001] The invention belongs to the technical field of slope drilling, and in particular relates to open-air slope drilling construction equipment and a use method thereof. Background Art

[0002] Open-pit mine slope reinforcement is to improve the stability of open-pit mine slopes by setting up slope foot retaining walls at the foot of the slope fracture zone, setting anti-slide piles in the local fracture zone or on the slope, and grouting into rock strata with open joints and cracks. The working principle of slope drilling construction equipment mainly depends on the mechanical crushing ability of the drilling rig.

[0003] After searching, the publication number: CN221682902U announced a drilling device for open-pit mining slope blasting construction. The support tube is rotated inside the rotating seat, and then the insertion rod is pulled out and inserted into the ground. At this time, the movable rod rotates with the support tube, so that the slider slides inside the sliding box. When the angle adjustment of the support tube is completed, the extrusion block is driven to extrude the T-bar by rotating the screw rod. At this time, the movement of the T-bar causes the first telescopic spring to stretch, so that the insertion block and the slot are engaged and fixed, thereby achieving the effect of quickly adjusting the support shell. The effect of the slider sliding inside the sliding box makes it easier to fold the support tube later, which brings convenience to the staff when using it. After the insertion rod is inserted into the ground, the fixing knob is tightened, so that the staff can adjust and fix it according to the hardness of the ground.

[0004] The above patent only realizes the directional drilling operation of the equipment. When the height of the slope is high and the slope is steep, this equipment cannot adjust the drilling direction according to the slope of the slope, thereby failing to ensure the vertical consolidation of the anchor rod or fixing device in the slope. When drilling, due to the large amount of heat and gas generated by the friction and cutting action of the drill bit, the drill bit is subjected to high pressure, high temperature and friction during the drilling process for a long time, which will destroy its original structural strength and lead to reduced drilling efficiency. In addition, the drilling distance of traditional equipment is limited and its practicality is average.

[0043] like Figure 1-8 An open-air slope drilling construction equipment shown in the figure includes a crawler body 1, a mounting frame 2, a Z-axis movable table 3, a drill nut 4, a rotating assembly 5, a lowering drill assembly 6 and an exhaust assembly 7, wherein the rotating assembly 5 is rotatably connected to one side of the crawler body 1, the mounting frame 2 is fixedly connected to the outer side of the rotating assembly 5, the Z-axis movable table 3 is sleeved on the inner side of the mounting frame 2, the drill nut 4 is arranged below the Z-axis movable table 3, the lowering drill assembly 6 is installed on the top of the mounting frame 2, and the exhaust assembly 7 is arranged on the inner side of the drill nut 4;

[0044] The mounting frame 2 is driven by the driver to drive the crawler vehicle body 1 to the drilling position of the open-air slope and is used to support the lower drilling assembly 6. The lower drilling assembly 6 is used to connect the barrel drill 4 and extend the lower drilling. The rotating assembly 5 is used to drive the mounting frame 2 and the outer barrel drill 4 to fine-tune along the slope and drill perpendicular to the slope of the slope. The barrel drill 4 is used for drilling holes in the open-air slope. The exhaust assembly 7 is used to absorb the internal heat of the high-speed rotating barrel drill 4 and discharge it.

[0045] The device controls the outer mounting frame 2 and the barrel drill 4 through the rotating component 5 to make fine adjustments along the slope, ensuring that the barrel drill 4 always drills perpendicular to the slope of the slope, so that the drilled hole after drilling can ensure that the anchor rod or fixing device is vertically consolidated in the slope, thereby improving stability and safety.

[0046] The drilling assembly 6 includes a connecting cover 61, a DC motor 62, a threaded rod 63, a protective cover 64, an asynchronous motor 65, a drill rod 66 and a re-extension portion 67. The DC motor 62 is threadedly connected to the top of the mounting frame 2, the threaded rod 63 is installed below the output end of the DC motor 62 and is screwed to one side of the Z-axis movable table 3, the connecting cover 61 is fixedly connected to the top of the Z-axis movable table 3, the protective cover 64 is movably connected to the bottom of the Z-axis movable table 3, the asynchronous motor 65 is threadedly connected to the inside of the protective cover 64, the drill rod 66 is fixedly connected to the outside of the output end of the asynchronous motor 65, and the re-extension portion 67 is arranged inside the connecting cover 61.

[0047] The mounting frame 2 and the drill bit 4 are connected to the crawler vehicle body 1 through a rotating joint 51. The coordinated action of the heavy oil cylinder 52 and the articulated rod 53 enables the mounting frame 2 and the drill bit 4 to be fine-tuned along the slope to ensure the verticality of the drilling hole.

[0048] The exhaust assembly 7 includes a clamping plate 71, a supporting truncated cone 72, an axial flow fan 73, a porous ventilation pipe 74 and an exhaust pipe 75. The clamping plate 71 is slidably sleeved on the inner side of the top of the barrel drill 4, the supporting truncated cone 72 is fixedly connected to one end of the clamping plate 71, the axial flow fan 73 is installed in the middle of the top of the supporting truncated cone 72, the porous ventilation pipe 74 is installed below the air inlet end of the axial flow fan 73, and the exhaust pipe 75 is installed on the outside of the output end of the axial flow fan 73.

[0049] The DC motor 62 drives the threaded rod 63 to rotate, driving the Z-axis movable table 3 and the barrel drill 4 to descend in the vertical direction. The asynchronous motor 65 drives the drill rod 66 to rotate to achieve the drilling operation. The hydraulic cylinder 671 and the push rod 672 provide additional drilling force and stability.

[0050] The rotating assembly 5 includes a rotating joint 51, a heavy-duty oil cylinder 52 and an articulated rod 53.

One side of the articulated rod 53 is fixedly connected to the output end of the heavy-duty oil cylinder 52, and the other side of the articulated rod 53 is hinged to the bottom surface of one side of the mounting frame 2.

[0051] This device absorbs and discharges the heat inside the barrel drill 4. The device can maintain the normal operating temperature of the drill bit, extend its service life, and avoid the reduction of drilling efficiency due to high temperature. The heat and gas are compressed by the axial flow fan 73 and discharged through the exhaust pipe 75 to ensure the normal operating temperature of the barrel drill 4.

[0052] The further extension portion 67 includes a hydraulic cylinder 671 and a push rod 672 . The hydraulic cylinder 671 is threadedly connected to the inner side of the connecting cover 61 . The push rod 672 is fixedly connected below the output end of the hydraulic cylinder 671 and is fixedly connected to the middle of the top end of the protective cover 64 .

[0053] By controlling the speed and direction of the DC motor 62, the descending speed of the Z-axis movable table 3 and the barrel drill 4 can be accurately adjusted to control the depth of the drilling. The hydraulic cylinder 671 applies additional thrust to the protective cover 64 through the push rod 672 to further increase the stability and depth of the drilling.

[0054] The axial flow fan 73 sucks the heat and gas inside the barrel drill 4 through the porous ventilation pipe 74, and discharges them through the exhaust pipe 75 after compression, thereby ensuring the normal working temperature of the barrel drill 4.

[0055] The drilling assembly 6 of the device has a longer drilling distance, so that the equipment can perform drilling operations in deeper slopes, thereby improving the practicability and application range of the equipment.

[0056] The bottom of the drill bit 4 is also provided with a plurality of groups of annular arrays of insert teeth 8 .

[0057] Several groups of annular arrays of insert teeth 8 arranged at the bottom enhance the efficiency and accuracy of drilling.

[0058] A linear shaft 9 is also provided on the inner side of the mounting frame 2 . The linear shaft 9 passes through the inner side of the Z-axis movable table 3 and is fixedly connected to the surface of the mounting frame 2 .

[0059] The Z-axis movable table 3 has a thread groove 10 and a through hole 11 respectively penetrating therein, the thread groove 10 and the through hole 11 being matched with the sizes of the threaded rod 63 and the linear axis 9 .

[0060] The threaded rod 63 and the linear axis 9 are connected to each other through the threaded groove 10 and the through hole 11, respectively, to achieve vertical movement and stability. The hydraulic buffer 12 further improves the stability and safety of the Z-axis movable table 3 during movement.

[0061] Hydraulic buffers 12 are also installed around the Z-axis movable table 3.

[0062] A method for using the open-pit slope drilling construction equipment is also proposed, which is carried out using the above-mentioned device and includes the following steps:

[0063] S1, the driver drives the crawler body 1 to the predetermined open-pit slope drilling position;

[0064] S2. According to the specific slope of the slope, the angles of the mounting frame 2 and the drill 4 are adjusted by the rotating assembly 5;

[0065] S3, start the drilling assembly 6, drive the barrel drill 4 to start drilling, and simultaneously adjust the height of the Z-axis movable table 3 to control the feeding depth of the barrel drill 4;

[0066] S4, the exhaust assembly 7 operates to absorb the heat inside the barrel drill 4 and discharge it.

[0067] Working principle: The driver drives the crawler body 1 to the predetermined open-air slope drilling position. The crawler is designed to enable it to travel stably in rugged terrain. According to the slope of the slope, the angles of the mounting frame 2 and the barrel drill 4 are fine-tuned through the rotating assembly 5 to ensure that they can drill perpendicular to the slope of the slope. The DC motor 62 is started to drive the threaded rod 63 to rotate. Since the threaded rod 63 is screwed to one side of the Z-axis movable table 3, the rotation of the threaded rod 63 will drive the Z-axis movable table 3 and the barrel drill 4 below it to descend in the vertical direction. At the same time, the asynchronous motor 65 is started inside the protective cover 64 to drive the drill rod 66 to rotate, thereby driving the barrel drill 4 to perform drilling operations; by controlling the speed and direction of the DC motor 62, the descending speed of the Z-axis movable table 3 and the barrel drill 4 can be accurately adjusted to control the depth of the drilling. The hydraulic cylinder 671 applies additional thrust to the protective cover 64 through the push rod 672 to further increase the stability and depth of the drilling. During the drilling process, the high-speed rotation of the barrel drill 4 will generate a lot of heat. At this time, the exhaust assembly 7 starts to work, the axial flow fan 73 starts, and the heat and gas inside the barrel drill 4 are sucked in through the porous ventilation pipe 74. After the heat and gas are compressed by the axial flow fan 73, they are discharged through the exhaust pipe 75 to ensure the normal working temperature of the barrel drill 4. When the predetermined drilling depth is reached, the DC motor 62 and the asynchronous motor 65 are stopped.

[0068] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
