[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0033] Currently, the drilling equipment on the market usually involves mounting drilling equipment on an engineering vehicle. This type of drilling equipment can be adjusted with multiple degrees of freedom and can be used for drilling in different directions and angles. However, this type of equipment is often complex in structure, large in size, and not suitable for construction in mountainous mining areas with complex terrain conditions.
[0034] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the blast hole construction device for mining engineering includes:
[0035] Vehicle body 10; Vehicle body 10 has the function of self-propelled movement, for example, by using existing unmanned vehicle technology, the vehicle body is controlled to move by a remote control. Tracked wheels 11 are installed on the vehicle body 10 to adapt to driving under different terrain conditions.
[0036] Drilling unit; The drilling unit includes a fixed frame 21 mounted on the vehicle body, a drill bit, and a drive mechanism. The fixed frame 21 is fixedly mounted on the vehicle body. The drill bit for drilling is mounted on a sliding member 22. The sliding member 22 is slidably fitted on the fixed frame 21 so that the sliding member can slide on the fixed frame. A drive mechanism is set between the sliding member and the fixed frame. The drive mechanism drives the sliding member to slide on the fixed frame so that the drill bit can drill along the vertical direction of the vehicle body to perform drilling operations.
[0037] Support unit; The support unit is installed on the vehicle body and includes at least three support members 31 that can extend and retract along the vertical direction of the vehicle body. The support members 31 are arranged around the perimeter of the vehicle body. When the support members are supported on the ground, they can support the vehicle body. The vehicle body can be adjusted to be horizontal by adjusting the support of multiple support members.
[0038] The tracked wheels enable the self-propelled vehicle to move freely in complex mining conditions, without being restricted by the conditions of the construction site.
[0039] In actual construction sites, due to limitations in ground conditions, the vehicle body may be tilted and unstable at the construction location. Under such circumstances, drilling operations often struggle to guarantee the quality of the drilling. Using support units to support the vehicle body ensures its stability, and the support forces provided by multiple supports at different locations allow for adjustments to the vehicle body's position.
[0040] The vehicle body is adjusted using a support unit, and during drilling, the vehicle body is adjusted to be horizontal. Since the drill bit on the drilling unit is set to drill vertically along the vehicle body, the verticality of the borehole can be well guaranteed when the drill bit is adjusted to be horizontal.
[0041] The drilling unit is fixedly mounted on the vehicle body, which is simple in structure and has few moving parts, resulting in better overall stability and thus ensuring the construction quality of the boreholes.
[0042] In some embodiments, the drive mechanism includes a drive motor 23 and a lead screw 24 mounted on a fixed frame. The lead screw 24 is rotatably connected to the fixed frame 21 at both ends via bearings. The drive motor drives the lead screw to rotate. A sliding member 22 is connected to the lead screw 24 via a transmission connection, and the rotation of the lead screw 24 drives the sliding member to move. Using a lead screw drive not only improves the accuracy of the feed but also enhances the stability of the drilling feed.
[0043] In some embodiments, a drill template 26 is provided at the lower end of the fixing frame 21. The drill template 26 has a drill jig hole 261 that mates with the drill bit. When machining deep and long holes, it can guide the drill bit and ensure drilling quality. Generally, a drill bushing can be installed in the drill jig hole. The drill bushing is usually made of cemented carbide, and the drill bushing is usually designed to be detachably connected to the drill template for easy replacement.
[0044] The drilling template also serves as a protective measure, preventing material from splashing during drilling.
[0045] Based on the setup of the drill template, guide posts 27 are installed between the drill template 26 and the fixed frame 21. Generally, two guide posts can be used to connect the sliding component to the guide posts in a sliding fit. Through the sliding fit between the guide posts and the sliding component, the stability of the sliding component's movement is further improved, ensuring the drilling accuracy of the drill bit.
[0046] Drilling tools typically include a drill rod 252 and a motor 251. The motor 251 drives the drill rod 252 to rotate, and the drill rod performs drilling operations under the feed force of the lead screw.
[0047] Reference Figure 1 A stabilizer 28 is installed on the polished section of drill rod 252. The drill rod 252 and the stabilizer 28 are rotatably connected, while the stabilizer 28 and the guide post 27 are slidably connected. In this configuration, the stabilizer, along with the guide post, guides and supports the drill rod, ensuring its stability during drilling and preventing it from jumping during drilling in hard rock formations.
[0048] Reference Figure 4 The centralizer 28 includes a centralizer plate 281, a rolling bearing 282 mounted on the centralizer plate, two stabilizing arms 283 connected to the centralizer plate, and centralizer sleeves 284 connected to the stabilizing arms. The centralizer is fixedly connected to the drill pipe via the rolling bearing, achieving a rotatable connection between the drill pipe and the centralizer; the two centralizer sleeves are respectively fitted onto the guide post and slidably connected to the guide post, achieving a sliding connection between the centralizer and the guide post.
[0049] In some embodiments, the borehole construction apparatus further includes a level 40 for detecting the levelness of the vehicle body. The level 40 is mounted on the vehicle body or on the drilling template, and is used to detect the levelness of the vehicle body in its current state. The level can be mechanical or electronic.
[0050] In some embodiments, a frame 13 is provided on the vehicle body 10, and the support unit adopts four support members 31. The four support members 31 are fixedly arranged on the frame 13 around the vehicle body to ensure the stability of the connection between the support members and the vehicle body, so as to achieve stable support for the vehicle body.
[0051] Support component 31 adopts an electric push rod, which is electrically controlled to realize the extension and retraction adjustment of each support component. A support plate is set at one end of the electric push rod, and the electric push rod and the support plate are connected by a ball joint. While increasing the contact area between the support component and the ground, it can adapt to stable support under various terrain conditions.
[0052] The adjustment of the vehicle body level can be achieved by program control. Accordingly, an electronic level is used. By acquiring data from the electronic level, control commands are output to each electric push rod to control the extension and retraction of the electric push rods, so that the vehicle body is automatically adjusted to be level. The control program can be implemented based on existing control logic and commands.
[0053] A scale 29 is provided on the fixed frame 21. During the drilling operation, the drilling depth can be obtained by reading the movement distance of the sliding part, thus realizing the measurement of the hole depth.
[0054] A counterweight 12 is installed on the vehicle body 10 to increase the weight of the vehicle body and ensure the stability of the drilling operation.
[0055] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0056] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0057] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
