Description

Technical Field

[0001] The utility model relates to the technical field of blasting drilling, in particular to an open-air blasting drilling device. Background Art

[0002] The most commonly used construction method for open-pit blasting is the drilling and blasting method, which is a method of excavating rocks by drilling, charging, and blasting. The drilling step mainly involves drilling a regular number of blast holes on the construction surface through a drilling device, then placing explosives into the blast holes, igniting the explosives, and blasting and demolishing the buildings that need to be demolished. In some cases, manual drilling is required, such as in areas with complex terrain, such as steep slopes, gullies, etc., where mechanical equipment is difficult to reach or operate stably; or because there are a large number of cracks and voids in the rock, it is difficult for mechanical drilling equipment to operate stably.

[0003] In the prior art, there is a blasting drilling device for open-pit mining proposed in the publication number CN213869718U, which includes a bottom box, a working box, a controller and a drilling box, a vertical plate is arranged at the upper end of the bottom box, the lower end of the vertical plate is fixedly connected to the upper end of the bottom box, a working box is arranged at the upper end of the vertical plate, the outer wall of the working box is rotatably connected to the upper end of the vertical plate through an axis, a hydraulic push rod is arranged below the left end of the working box, the upper end of the hydraulic push rod is rotatably connected to the lower end of the working box through a hinge seat, a drilling box is arranged at the left end of the working box, a drilling motor is arranged inside the drilling box, and a drill bit is arranged in the middle of the left end of the drilling box. The utility model can adjust the drilling position distance and angle of the ore by arranging a drilling box that is easy to move and a working box that can be rotated up and down, and the inserted rods arranged at the same time can reinforce the device and improve the working efficiency.

At this time, when it is necessary to drill a hole in the ground, the drilling mechanism is not convenient for drilling vertically downward. At the same time, some steep terrains make it difficult to move the bottom box, which in turn affects the progress of the drilling work. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example: Refer to Figure 1-Figure 4 The open-air blasting drilling device disclosed in the utility model comprises a support rod 1 and a drilling mechanism 2, characterized in that a mounting block 3 is connected to the side of the support rod 1, an adjusting member 4 is connected to the end of the mounting block 3, and a fixing member 5 is arranged on the outer peripheral side of the support rod 1;

[0027] The adjusting member 4 includes a load-bearing rod 6, a fixed block 7, a slide rail 8 and a slider 9. The load-bearing rod 6 is fixedly installed on the side of the mounting block 3. The fixed block 7 is sleeved on the end of the load-bearing rod 6 and is rotatably connected to the load-bearing rod 6. An avoidance groove 10 is provided at the end of the fixed block 7 away from the support rod 1. An adjusting rod 11 is provided on the side of the fixed block 7. The end of the adjusting rod 11 passes through the fixed block 7 and is fixedly connected to the fixed block 7. The slide rail 8 is provided in the avoidance groove 10. The slide rail 8 is sleeved on the adjusting rod 11 and is rotatably connected to the adjusting rod 11. The slider 9 is slidably installed on the slide rail 8. The drilling mechanism 2 is fixedly installed on the side of the slider 9 away from the slide rail 8.

[0028] In this embodiment, when in use, the support rod 1 is inserted into the soil around the hole to be blasted and rotated, and the rotation drives the drilling mechanism 2 to a suitable position, and then fixed by the set fixing piece 5, and then the drilling mechanism 2 is held by hand, and the slide rail 8 is driven to rotate on the adjustment rod 11 by pushing or pulling the drilling mechanism 2, and at the same time, the set fixing block 7 can be driven to rotate on the bearing rod 6, so that the drilling mechanism 2 can adjust the angle in multiple directions, wherein the avoidance groove 10 is used to avoid the slide rail 8, so as to avoid the slide rail 8 being limited by the fixing block 7 when rotating, thereby affecting the rotation, wherein the installation block 3 is used to separate the slide rail 8 from the support rod 1, so as to avoid the slide rail 8 from touching the support rod 1 and being resisted when rotating, and the width of the installation block 3 can be adjusted according to the implementation situation;

[0029] After the angle adjustment is completed, the drilling mechanism 2 is pushed so that the drilling mechanism 2 moves on the slide rail 8 through the slider 9, and the drill bit of the drilling mechanism 2 is pressed against the position where the hole needs to be drilled. At this time, the drill bit finds the fulcrum, and the drilling mechanism 2 is started and drilling is performed. As the drilling mechanism 2 drives the drill bit to drill, the drilling mechanism 2 will continue to slide in the direction of drilling on the slide rail 8 through the slider 9, thereby achieving the purpose of drilling. During the drilling work, the end of the drill bit of the drilling mechanism 2 and the position of the hole are used as fulcrums. Therefore, the angle of the slide rail 8 and the angle of the fixed block 7 are limited by the drill bit of the drilling mechanism 2 and cannot change the angle. At the same time, there is a support rod 1 for support, thereby ensuring that the angle deviation is avoided during drilling.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, a driving motor 12 is fixedly connected to the bottom end of the slide rail 8 , a driving screw 13 is connected to the output end of the driving motor 12 , and an end of the driving screw 13 passes through the slider 9 and is threadedly connected to the slider 9 .

[0031] In this embodiment, the driving motor 12 is arranged to drive the driving screw 13 to rotate, and then the sliding block 9 is driven to move on the sliding rail 8 through the rotation of the driving screw 13. Therefore, when performing drilling work, the staff only needs to hold the drilling mechanism 2 in the initial state to adjust the angle. When the drill bit of the drilling mechanism 2 is drilling, it only needs to control the drive of the driving motor 12 so that the drilling mechanism 2 can gradually move in the direction of drilling, which simplifies the working steps during drilling work and improves practicality.

[0032] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the fixing member 5 includes a driving part and a limiting part, the limiting part includes a number of notches 14, the notches 14 are opened at the bottom of the outer peripheral side of the support rod 1, a rotating shaft 15 is rotatably connected in the notch 14, a clamping rod 16 is rotatably connected on the rotating shaft 15, a number of resistance pieces 17 are fixedly connected to the bottom end of the clamping rod 16, the support rod 1 is hollow, and a shift plate 19 is fixedly connected to the top of one side of the clamping rod 1 close to the support rod 1.

[0033] In this embodiment, after the support rod 1 is inserted into the ground, the driving unit pushes the dial plate 19 and drives the clamping rod 16 to rotate on the rotating shaft 15, so that the resistance piece 17 at the bottom of the clamping rod 16 resists the side wall of the hole and is inserted into the soil at the same time, to prevent the vibration generated by the support rod 1 when the drilling mechanism 2 is drilling, which drives the position or angle of the support rod 1 to deviate, thereby affecting the progress of the drilling work.

[0034] In a further preferred embodiment of the present invention, Figure 3-4As shown, torsion springs 18 are disposed at both ends of the rotating shaft 15 , and both ends of the torsion spring 18 are fixedly connected to the side wall of the clamping rod 16 and the inner side wall of the notch 14 , respectively.

[0035] In this embodiment, when the clamping rod 16 rotates, it will also drive the torsion spring 18 to rotate, and cause the torsion spring 18 to generate a reaction force of movement. After the drilling is completed, when the support rod 1 needs to be pulled out, the limit on the clamping rod 16 is released by the driving part, so that the clamping rod 16 can be driven to reset by the reaction force of the torsion spring 18, thereby facilitating the support rod 1 to be taken out of the hole.

[0036] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the driving part includes a limiting screw rod 20 , and the limiting screw rod 20 is inserted from the top of the support rod 1 and is threadedly connected to the support rod 1 .

[0037] In this embodiment, the limiting screw rod is arranged to rotate inside the support rod 1, so that the limiting screw rod 20 moves downward, thereby pushing the shift plate 19. The shift plate 19 will drive the clamping rod 16 to rotate on the rotating shaft 15, thereby inserting the resistance piece 17 into the inner wall of the hole, thereby completing the positioning of the support rod 1 and improving the stability of the drilling mechanism 2 during drilling.

[0038] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the bottom end of the limiting screw rod 20 is rotatably connected to a mounting shaft 21 , and the bottom end of the mounting shaft 21 is fixedly connected to a push plate 22 , and the push plate 22 is slidably connected to the inner peripheral wall of the support rod 1 .

[0039] In this embodiment, the installation shaft 21 is used to install the push plate 22, so that when the limiting screw 20 rotates downward, it will drive the push plate 22 to slide downward, thereby pushing the dial plate 19, thereby avoiding the rotation of the screw and the friction between the dial plate 19, which increases the wear after long-term use and reduces the service life of the dial plate 19.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
