Description

Technical Field

[0001] This utility model relates to the field of rapid drilling devices for blasting holes, and in particular to a rapid drilling device for blasting holes. Background Technology

[0002] In many areas of the mining construction industry, blasting devices are frequently used to blast open mine areas, which can greatly reduce the danger to workers. Blasting can be carried out simply by placing explosives into pre-drilled blasting holes. The detonators used in blasting require pre-drilling and positioning of the holes before installation; the accuracy of the drilling largely determines the accuracy of the blast. Therefore, this utility model mainly provides a device for positioning and drilling holes, improving drilling accuracy.

[0003] In existing technologies, such as the "Positioning and Drilling Device for Blasting" (Chinese Patent Publication No. CN220487502U), a support plate and a drilling shaft are included. A motor for driving the drilling shaft is mounted on the upper side of the support plate. The drilling shaft passes vertically through the center of the support plate. The support plate is provided with a guide post for moving the motor, limiting the motor's movement along the length of the guide post. The guide post is vertically fixed to the support plate. A through hole for the drilling shaft to move is opened in the center of the support plate. First, the drilling position is located, then the support plate is installed and supported on the ground by a support frame (a flat strip structure) to ensure stability. The drilling shaft is then used for positioning and drilling. The motor is then moved along the drilling direction to perform the drilling, achieving fast and accurate drilling operations.

[0004] In existing technologies, when drilling blasting holes, the soil in most boreholes is quite hard, requiring manual pressing of the handle to sink the drill shaft into the ground, which makes drilling quite laborious.

[0005] Therefore, it is necessary to provide a rapid drilling device for blasting holes to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a rapid drilling device for blasting holes, which solves the problem that drilling is laborious because most drilling geology and soil are relatively hard, requiring manual pressing of the handle to sink the drill shaft into the ground.

[0007] To solve the above-mentioned technical problems, this utility model provides a rapid drilling device for blasting holes, including a support platform, a limiting column fixedly connected to the top of the support platform, a top plate fixedly connected to the top of the limiting column, a lifting frame movably sleeved on the outside of the limiting column, a drive motor fixedly installed inside the lifting frame, a drilling impeller fixedly connected to the output shaft of the drive motor, a first gear fixedly sleeved on the output shaft of the drive motor, a threaded rod movably sleeved inside the lifting frame, a second gear fixedly sleeved at the bottom of the threaded rod, a counterweight mechanism provided on the top of the support platform, a bearing movably sleeved on the top of the lifting frame, and a moving mechanism provided on the bottom of the support platform.

[0008] Preferably, the second gear meshes with the first gear, and there are two second gears, which are symmetrically distributed about the first gear as an axis of symmetry.

[0009] Preferably, the limiting posts and the support platform are perpendicular to each other, and the number of limiting posts is four.

[0010] Preferably, the counterweight mechanism includes a threaded column, which is threadedly sleeved on the top of the support platform, and a counterweight block is movably sleeved on the outside of the threaded column.

[0011] Preferably, the bearing is movably sleeved on the outside of the threaded rod, and the number of bearings is four.

[0012] Preferably, the moving mechanism includes a pusher frame, which is fixedly connected to one side of the top of the support platform, and a support column is fixedly connected to the bottom of the support platform, with sliding wheels installed at the bottom of the support column.

[0013] Compared with related technologies, the rapid drilling device for blasting holes provided by this utility model has the following beneficial effects:

[0014] This utility model provides a rapid drilling device for blasting holes. By setting a second gear, when blasting hole drilling is required, the drive motor is started, which drives the drilling impeller to rotate. At this time, the drive motor drives the second gear through the first gear to rotate, which drives the threaded rod to rotate. This allows the threaded rod to slowly descend inside the top plate, which in turn drives the lifting frame to slowly descend. This achieves the effect of the drilling impeller slowly descending during drilling, thus bringing great convenience to blasting drilling.

[0015] By setting up a moving mechanism, when the drilling device needs to be moved and transported, the pusher frame is pushed so that the sliding wheel can drive the support platform to move horizontally through the support column, which in turn drives the drilling impeller to move horizontally, thereby achieving the effect of moving and transporting the drilling device, and thus bringing convenience to the moving operation of the drilling device.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of a rapid drilling device for blasting holes provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a drilling impeller in a rapid drilling device for blasting holes. Figure 3 for Figure 1 The image shows a front view of a support platform in a rapid drilling device for blasting holes. The device includes a support platform 1, a limiting post 2 fixedly connected to the top of the support platform 1, a top plate 3 fixedly connected to the top of the limiting post 2, a lifting frame 4 movably sleeved outside the limiting post 2, a drive motor 5 fixedly installed inside the lifting frame 4, a drilling impeller 6 fixedly connected to the output shaft of the drive motor 5, a first gear 7 fixedly sleeved on the output shaft of the drive motor 5, a threaded rod 8 movably sleeved inside the lifting frame 4, a second gear 9 fixedly sleeved at the bottom of the threaded rod 8, a counterweight mechanism 10 on the top of the support platform 1, a bearing 11 movably sleeved on the top of the lifting frame 4, and a moving mechanism 12 on the bottom of the support platform 1.

[0022] Gear 9 is meshed with gear 7, and there are two gears 9, which are symmetrically distributed about gear 7. By setting gear 9, when drilling for blasting holes, the drive motor 5 is started, which drives the drilling impeller 6 to rotate. At this time, the drive motor 5 drives gear 9 to rotate through gear 7, which in turn drives the threaded rod 8 to rotate. This causes the threaded rod 8 to slowly descend inside the top plate 3, which in turn drives the lifting frame 4 to slowly descend. This achieves the effect of the drilling impeller 6 slowly descending when drilling, which greatly facilitates blasting drilling.

[0023] The limiting posts 2 are perpendicular to each other and there are four limiting posts 2. By setting the limiting posts 2, when the threaded rod 8 drives the lifting frame 4 to move up and down, the limiting posts 2 can limit the lifting frame 4 to move up and down, so as to avoid the problem of deflection when the lifting frame 4 moves up and down, thereby improving the stability of the drilling impeller 6 when it rises and falls.

[0024] The counterweight mechanism 10 includes a threaded post 101, which is threaded onto the top of the support platform 1. A counterweight block 102 is movably sleeved on the outside of the threaded post 101. By setting the counterweight mechanism 10, when drilling blast holes, the counterweight block 102 greatly increases the weight of the support platform 1, thereby avoiding the problem of the support platform 1 swaying up and down when the drilling impeller 6 is drilling, thus improving the stability of the support platform 1.

[0025] The bearing 11 is movably sleeved on the outside of the threaded rod 8, and there are four bearings 11. By setting the bearings 11, when the threaded rod 8 rotates, the bearings 11 can limit the rotation of the threaded rod 8, thereby avoiding the problem of friction between the threaded rod 8 and the lifting frame 4 during long-term rotation, thus improving the smoothness of the rotation of the threaded rod 8.

[0026] The moving mechanism 12 includes a pusher frame 121, which is fixedly connected to one side of the top of the support platform 1. A support column 122 is fixedly connected to the bottom of the support platform 1, and a sliding wheel 123 is installed at the bottom of the support column 122. By setting up the moving mechanism 12, when it is necessary to move and transport the drilling device, the pusher frame 121 is pushed, so that the sliding wheel 123 can drive the support platform 1 to move horizontally through the support column 122, that is, drive the drilling impeller 6 to move horizontally, thereby achieving the effect of moving and transporting the drilling device, and thus bringing convenience to the moving operation of the drilling device.

[0027] The working principle of the rapid drilling device for blasting holes provided by this utility model is as follows:

[0028] First, when drilling for blasting holes is required, the drive motor 5 is started, causing the drill impeller 6 to rotate. The drive motor 5 then drives the second gear 9 via the first gear 7, which in turn drives the threaded rod 8 to rotate. This causes the threaded rod 8 to slowly descend inside the top plate 3, thus slowly lowering the lifting frame 4. This achieves the effect of the drill impeller 6 descending slowly during drilling, greatly facilitating blasting drilling. When the threaded rod 8 moves the lifting frame 4 up and down, the limiting post 2 limits the movement of the lifting frame 4, preventing deflection and improving the stability of the drill impeller 6 during lifting. During drilling, the counterweight 102 greatly increases the weight of the support platform 1, preventing the drilling impeller 6 from causing the support platform 1 to sway up and down, thus improving the stability of the support platform 1. When the threaded rod 8 rotates, the bearing 11 limits the rotation of the threaded rod 8, preventing the threaded rod 8 from rubbing against the lifting frame 4 during long-term rotation, thus improving the smoothness of the rotation of the threaded rod 8. When the drilling device needs to be moved and transported, the pusher frame 121 is pushed, so that the sliding wheel 123 can drive the support platform 1 to move horizontally through the support column 122, that is, drive the drilling impeller 6 to move horizontally, thus achieving the effect of moving and transporting the drilling device, thereby bringing convenience to the moving operation of the drilling device.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
