Description

Technical Field

[0001] The utility model relates to the technical field of ore body blasting, in particular to a blast hole arrangement structure for ore body roadway tunneling blasting. Background Art

[0002] Full-face blasting is a controlled blasting carried out by reasonably arranging peripheral holes according to the designed contour line of the roadway section, adopting a reasonable charge structure, and selecting an appropriate amount of explosive. The basic starting point of smooth blasting is to control the scope and direction of the blasting effect, minimize the disturbance to the surrounding rock, and make the current situation of the surrounding rock of the roadway after blasting regular and smooth, meeting the design requirements. Therefore, in the process of ore body roadway tunneling blasting, how to arrange the blast holes is also an important step.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: During the hole-opening process of the ore body roadway, a machine is used for hole-opening. However, due to being inside the ore body roadway, the ground is not flat enough, resulting in the drill rig being unable to maintain balance during the hole-opening process, and thus it is easy to shake during the process of drilling the holes, which affects the quality of the drilled holes and reduces the stability of the device. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a blast hole arrangement structure for ore body roadway tunneling blasting.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: The blast hole arrangement structure for ore body roadway tunneling blasting includes a device main body. On the device main body, crawlers for driving the device main body are symmetrically arranged. On the upper surface of the device main body, a sliding rod is fixedly arranged. A connecting device is sleeved on the outer wall of the sliding rod, and the connecting device is slidably connected with the sliding rod. A drilling device for drilling holes is arranged on the connecting device. A supporting device for supporting the device main body is arranged on the device main body.

[0006] By adopting the above technical solutions, when the staff needs to carry out blast hole opening on the ore body roadway, the staff needs to install the used drill bit on the drilling device. Subsequently, the staff carries out hole opening on the ore body roadway. During this process, the staff can adjust the height of the drill bit by sliding the connecting device. In addition, during the hole-opening process, the staff needs to start the supporting device to support the device main body, thereby reducing the probability of the device main body shaking during the hole-opening process and improving the stability of the device.

[0007] Furthermore, a plurality of mounting grooves are arrayed and opened on the bottom surface of the device main body. The supporting device includes a plurality of first hydraulic rods respectively installed in the plurality of mounting grooves, a plurality of first support plates respectively arranged at the ends of the hydraulic shafts of the plurality of first hydraulic rods, two second hydraulic rods symmetrically arranged on the upper surface of the device main body, and two second support plates respectively arranged at the ends of the hydraulic shafts of the two second hydraulic rods.

[0008] By adopting the above technical solution, when hole opening is required, the staff needs to start the first hydraulic rod and the second hydraulic rod, so that the first support plate and the second support plate move towards the ground and the top of the mine tunnel respectively under the action of the first hydraulic rod and the second hydraulic rod, and then the first support plate and the second support plate respectively abut against the ground and the top of the mine tunnel. At this time, during the hole opening process, since the first support plate and the second support plate respectively abut against the ground and the top of the mine tunnel, the probability of the device main body shaking during the hole opening process is reduced, thereby improving the stability of the device.

[0009] Furthermore, the connecting device includes a frustum sleeved on the outer wall of the sliding rod, a U-shaped member fixedly arranged on the outer wall of the frustum, and a third hydraulic rod fixedly arranged on the outer wall of the frustum. The drilling equipment is fixedly connected to the hydraulic shaft of the third hydraulic rod.

[0010] By adopting the above technical solution, during the hole opening process, the staff needs to start the third hydraulic rod, so that the hydraulic shaft of the third hydraulic cylinder moves, thereby enabling the drilling equipment to move under the action of the hydraulic shaft, and further enabling the hole opened by the drill bit under the action of the drilling equipment to reach the required depth. During this process, the difficulty for the staff to move the drilling equipment is reduced, thereby reducing the work difficulty of the staff.

[0011] Furthermore, rotating blocks are fixedly arranged at the ends of the hydraulic shafts of the first hydraulic rod and the second hydraulic cylinder. Rotating grooves are opened on the side walls of the plurality of rotating blocks, and rotating rods are rotatably arranged in the plurality of rotating grooves. The plurality of rotating rods are respectively fixedly connected to the adjacent first support plate or second support plate.

[0012] By adopting the above technical solution, when the first support plate and the second support plate respectively abut against the ground and the top of the mine tunnel, since the ground and the top of the mine tunnel are not flat enough, the first support plate and the second support plate rotate under the action of the rotating rod, so that the first support plate and the second support plate are flush with the ground and the top of the mine tunnel under the action of the rotating rod, thereby reducing the probability of damage to the first support plate and the second support plate.

[0013] Furthermore, a rotating groove is opened inside the rotating groove, and a rotating rod is rotatably arranged in the rotating groove. The rotating rod penetrates through the rotating rod and is fixedly connected to the rotating rod.

[0014] By adopting the above technical solution, when the rotating rod rotates, the rotating bar rotates under the action of the rotating rod. During this process, the rotating bar limits the rotation of the rotating rod, thereby reducing the probability of shaking during the rotation of the rotating rod and improving the stability of the device.

[0015] Further, a reset groove is formed on the inner wall of the rotating groove, a torsion spring is fixedly arranged on the inner wall of the reset groove, and the other end of the torsion spring is fixedly arranged on the side wall of the rotating rod.

[0016] By adopting the above technical solution, when the first support plate and the second support plate are separated from the ground and the top of the mine tunnel, the rotating rod is reset under the action of the torsion spring, so that the first support plate and the second support plate are reset, thereby reducing the difficulty for the staff to reset the first support plate and the second support plate.

[0017] Further, a cylinder is fixedly arranged on the upper surface of the device body, and the end of the piston rod of the cylinder is fixedly connected with the connecting device.

[0018] By adopting the above technical solution, the cylinder reduces the difficulty for the staff to move the connecting device up and down, thereby reducing the difficulty for the staff to move the drilling equipment up and down, and thus reducing the working difficulty of the staff.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to perform blasting and opening on the ore body roadway, the staff needs to install the used drill bit on the drilling equipment. Subsequently, the staff opens the ore body roadway. During this process, the staff can adjust the height of the drill bit by sliding the connecting device. In addition, during the opening process, the staff needs to start the supporting device to support the device body, thereby reducing the probability of shaking of the device body during the opening process and improving the stability of the device;

[0021] 2. In this application, when opening is required, the staff needs to start the first hydraulic rod and the second hydraulic rod, so that the first support plate and the second support plate move towards the ground and the top of the mine tunnel respectively under the action of the first hydraulic rod and the second hydraulic rod, so that the first support plate and the second support plate are respectively abutted against the ground and the top of the mine tunnel. At this time, during the opening process, since the first support plate and the second support plate are respectively abutted against the ground and the top of the mine tunnel, the probability of shaking of the device body during the opening process is reduced, thereby improving the stability of the device;

[0022] 3. In this application, during the hole-opening process, the staff needs to start the third hydraulic rod, thereby moving the hydraulic shaft of the third hydraulic cylinder, so that the drilling equipment moves under the action of the hydraulic shaft, and then the depth of the hole drilled by the drill bit under the action of the drilling equipment meets the standard. During this process, the difficulty for the staff to move the drilling equipment is reduced, thus reducing the work difficulty of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-4 shown, the embodiment of the present application discloses a blasting hole layout structure for orebody roadway tunneling, including a device main body 1, crawlers 11, sliding rods 12, a connecting device 13, drilling equipment 14, a supporting device 3, a rotating block 4, a rotating rod 41, a rotating rod 5, and a torsion spring 6. Two crawlers 11 are provided and symmetrically arranged on the device main body 1 for driving the device main body 1. The sliding rod 12 is a round rod-shaped structure with its axis vertical, and the sliding rod 12 is fixedly arranged on the upper surface of the device main body 1. The connecting device 13 is sleeved on the outer wall of the sliding rod 12, and the connecting device 13 is slidably connected to the sliding rod 12. The drilling equipment 14 is arranged on the connecting device 13 for drilling.

[0030] When the staff needs to blast and open holes in the ore body roadway, the staff needs to install the drill bit used on the drilling equipment 14. Subsequently, the staff opens holes in the ore body roadway. During this process, the staff can adjust the height of the drill bit through the sliding connection device 13. In addition, during the hole-opening process, the staff needs to start the support device 3 to support the device body 1, thereby reducing the probability of the device body 1 shaking during the hole-opening process, and thus improving the stability of the device.

[0031] A plurality of installation grooves 2 are arranged in an array on the bottom surface of the device body 1. The support device 3 is arranged on the device body 1 and is used to support the device body 1. The support device 3 includes a first hydraulic rod 31, a first support plate 32, a second hydraulic rod 33, and a second support plate 34. A plurality of first hydraulic rods 31 are provided and are respectively installed in the plurality of installation grooves 2, and the axis of its hydraulic shaft is vertical. The first support plate 32 is a rectangular plate-like structure. A plurality of first support plates 32 are provided and are respectively arranged at the ends of the hydraulic shafts of the plurality of first hydraulic rods 31. Two second hydraulic rods 33 are provided and are symmetrically arranged on the upper surface of the device body 1, and the axis of its hydraulic shaft is vertical. The second support plate 34 is a rectangular plate-like structure. A plurality of second support plates 34 are provided and are respectively arranged at the ends of the hydraulic shafts of the two second hydraulic rods 33.

[0032] When hole opening is required, the staff needs to start the first hydraulic rod 31 and the second hydraulic rod 33, so that the first support plate 32 and the second support plate 34 respectively move towards the ground and the top of the mine tunnel under the action of the first hydraulic rod 31 and the second hydraulic rod 33, so that the first support plate 32 and the second support plate 34 respectively abut against the ground and the top of the mine tunnel. At this time, during the hole-opening process, since the first support plate 32 and the second support plate 34 respectively abut against the ground and the top of the mine tunnel, the probability of the device body 1 shaking during the hole-opening process is reduced, thereby improving the stability of the device.

[0033] The connection device 13 includes a frustum 131, a U-shaped member 132, and a third hydraulic rod 133. The frustum 131 is sleeved on the outer wall of the sliding rod 12, and its axis coincides with the axis of the sliding rod 12. The cross-section of the U-shaped member 132 is U-shaped, and the U-shaped member 132 is fixedly arranged on the side wall of the frustum 131. The third hydraulic rod 133 is fixedly arranged on the outer wall of the frustum 131, the axis of its hydraulic shaft is horizontal, and the drilling equipment 14 is fixedly connected to the hydraulic shaft of the third hydraulic rod 133.

[0034] During the hole-opening process, the staff needs to start the third hydraulic rod 133, so that the hydraulic shaft of the third hydraulic cylinder moves, so that the drilling equipment 14 moves under the action of the hydraulic shaft, so that the depth of the hole drilled by the drill bit under the action of the drilling equipment 14 meets the standard. During this process, the difficulty for the staff to move the drilling equipment 14 is reduced, thereby reducing the work difficulty of the staff.

[0035] A plurality of rotating blocks 4 are provided and are respectively fixedly arranged at the ends of the hydraulic shafts of a plurality of first hydraulic rods 31 and second hydraulic rods 33. Rotating grooves 21 are formed in the side walls of the plurality of rotating blocks 4. A plurality of rotating rods 41 are provided and are respectively rotatably arranged in the plurality of rotating grooves 21, and the plurality of rotating rods 41 are respectively fixed to the adjacent first support plate 32 or second support plate 34.

[0036] When the first support plate 32 and the second support plate 34 are respectively abutted against the ground and the top of the mine tunnel, since the ground and the top of the mine tunnel are not flat enough, the first support plate 32 and the second support plate 34 rotate under the action of the rotating rod 41, so that the first support plate 32 and the second support plate 34 are flush with the ground and the top of the mine tunnel under the action of the rotating rod 41, thereby reducing the probability of damage to the first support plate 32 and the second support plate 34.

[0037] A rotating groove 22 is formed in the inner part of the rotating groove 21. The rotating rod 5 is in a round rod shape structure, and its axis is horizontal. The rotating rod 5 is rotatably arranged in the rotating groove 22, and the rotating rod 5 penetrates through the rotating rod 41 and is fixed to the rotating rod 41.

[0038] When the rotating rod 41 rotates, the rotating rod 5 rotates under the action of the rotating rod 41. During this process, the rotating rod 5 limits the rotating rod 41, thereby reducing the probability of the rotating rod 41 shaking during rotation, and thus improving the stability of the device.

[0039] A reset groove 23 is formed in the inner wall of the rotating groove 22. One end of the torsion spring 6 is fixedly arranged on the inner wall of the reset groove 23, and the other end of the torsion spring 6 is fixedly arranged on the side wall of the rotating rod 5.

[0040] When the first support plate 32 and the second support plate 34 are separated from the ground and the top of the mine tunnel, the rotating rod 41 is reset under the action of the torsion spring 6, so that the first support plate 32 and the second support plate 34 are reset, thereby reducing the difficulty for the staff to reset the first support plate 32 and the second support plate 34.

[0041] In order to reduce the working difficulty of the staff, a cylinder 7 is fixedly arranged on the upper surface of the device main body 1, and the end of the piston rod of the cylinder 7 is fixed to the connecting device 13. The cylinder 7 reduces the difficulty for the staff to move the connecting device 13 up and down, thereby reducing the difficulty for the staff to move the drilling device 14 up and down, and thus reducing the working difficulty of the staff.

[0042] In this embodiment, the working principle of the blast hole layout structure for ore body roadway tunneling is as follows: When workers need to blast and drill holes in the ore body roadway, they need to install the drill bit used on the drilling equipment 14. Subsequently, the workers drill holes in the ore body roadway. During this process, the workers can adjust the height of the drill bit by driving the connecting device 13 through the cylinder 7. In addition, during the hole drilling process, the workers need to start the first hydraulic rod 31 and the second hydraulic rod 33, so that the first support plate 32 and the second support plate 34 move towards the ground and the top of the mine tunnel respectively under the action of the first hydraulic rod 31 and the second hydraulic rod 33, and then the first support plate 32 and the second support plate 34 are respectively pressed against the ground and the top of the mine tunnel. At this time, during the hole drilling process, since the first support plate 32 and the second support plate 34 are respectively pressed against the ground and the top of the mine tunnel, the probability of the device main body 1 shaking during the hole drilling process is reduced, thereby improving the stability of the device.
