In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, proposes a drilling vehicle with a multi-directional support mechanism, including: a drilling vehicle body, the drilling vehicle body has a drill rod portion 1; a plurality of support members 2, the plurality of support members 2 are arranged around the drill rod portion 1, the support members 2 are arranged at an angle to the drill rod portion 1, and the support members 2 include: a base frame 201, the base frame 201 is arranged on the drill rod portion 1; a limit support drill 202, the position of the limit support drill 202 is adjustable and arranged on the base frame 201, after the position of the limit support drill 202 is adjusted, the distance from the drill rod portion 1 changes, and the plurality of limit support drills 202 are used to support the guide drill rod portion 1.

[0024] In this embodiment, in field operation, when the drill rod part 1 of the drilling vehicle body performs drilling operation, several support members 2 arranged around the drill rod part 1 play an important role. The base frame 201 is arranged on the drill rod part 1, providing a stable installation foundation for the position-limiting support drill 202. The position-adjustable design of the position-limiting support drill 202 allows the operator to flexibly adjust the distance between the position-limiting support drill 202 and the drill rod part 1 according to the actual working environment and needs.

[0025] When the drilling vehicle is working in different terrains or complex geological conditions, due to the angled arrangement, the multiple limit support drills 202 can support and guide the drill rod 1 from different directions. This multi-directional support greatly improves the stability of the drill rod 1 during the drilling process, reduces the shaking and deviation caused by external interference, and thus improves the accuracy and quality of the drilling. At the same time, the adjustable limit support drill 202 can adapt to the drilling requirements of different hole diameters, enhancing the versatility and adaptability of the drilling vehicle.

[0026] In actual operation, firstly, according to the terrain of the work site and the drilling requirements, the position of the limit support drill 202 of each support member 2 on the main body of the drilling vehicle is adjusted on the base frame 201 so that it reaches a suitable distance from the drill rod part 1. Before the drill rod part 1 starts working, after the several limit support drills 202 arranged around the drill rod part 1 are adjusted to a suitable position, they drill into the side wall, change the distance from the drill rod part 1, and provide support guidance for the drill rod part 1 from different directions. When the drill rod part 1 is started and encounters external force interference during the drilling process, the multi-directional support can effectively reduce the shaking and deviation of the drill rod part 1, ensure the stable drilling operation, and improve the drilling accuracy and quality. This design also improves the safety of the operation. The stable support can reduce the risk of tipping or accidents of the drilling vehicle during the operation process, and protect the life safety of the operator. In addition, the multi-directional support mechanism also helps to improve the working efficiency of the drilling vehicle, reduce the time wasted due to adjusting the position of the drill rod, and make the drilling operation more efficient and smooth.

[0027] Furthermore, the drill rod portion 1 has a drill bit end 101, and also includes: a supporting sleeve 3, the supporting sleeve 3 is sleeved on the drill rod portion 1, the base frame 201 is set on the drill rod portion 1 through the supporting sleeve 3, the supporting sleeve 3 is a truncated cone, the position adjustment direction of the limiting support drill 202 is parallel to the main line direction of the supporting sleeve 3, and the cross-sectional area of ​​the supporting sleeve 3 gradually decreases from close to to far away from the drill bit end 101.

[0028] In this embodiment, under actual working conditions, the design of the support sleeve 3 of the drilling vehicle with a multi-directional support mechanism brings many beneficial effects. The support sleeve 3 is sleeved on the drill rod 1, providing a stable installation position for the base frame 201. Its truncated cone design and the cross-sectional area gradually decrease from close to far from the drill bit end 101 make the position adjustment direction of the limited support drill 202 parallel to the generatrix direction of the support sleeve 3, which is more in line with the principle of mechanics.

[0029] When the drilling vehicle is drilling, the truncated cone-shaped support sleeve 3 can better disperse the external force on the drill rod 1. As the drilling depth increases, the pressure near the drill bit end 101 is relatively large, and the shape of the support sleeve 3 can transfer part of the pressure to the limit support drill 202 to the surrounding area, thereby reducing the burden on the drill rod 1. The limit support drill 202 adjusts its position along the generatrix direction of the support sleeve 3, and can more accurately adapt to different operating requirements. Under complex geological conditions, the support position can be adjusted according to the actual situation to improve the stability of the drill rod 1, reduce shaking and deviation, and thus ensure the accuracy and quality of drilling. At the same time, this design also enhances the stability of the overall structure of the drilling vehicle, reduces the risk of accidents, and ensures the safety of operators.

[0030] Furthermore, both ends of the base frame 201 have a clamping portion 203, the length direction of the base frame 201 is parallel to the busbar direction of the supporting sleeve 3, the supporting sleeve 3 has two annular grooves 301, and a clamping portion 203 is adjustably arranged in an annular groove 301. After the position of the clamping portion 203 is adjusted, the relative positions of several base frames 201 change.

[0031] In this embodiment, the length direction of the base frame 201 is parallel to the busbar direction of the support sleeve 3, and the clamping parts 203 at both ends cooperate with the annular groove 301 of the support sleeve 3, so that the position of the base frame 201 can be flexibly adjusted. In actual drilling operations, operators can adjust the position of the base frame 201 according to different drilling requirements and geological conditions, thereby changing the relative position of the limit support drill 202 to achieve the best support effect. This flexible adjustment can improve the stability of the drill rod 1 in different working scenarios, reduce the shaking and deviation caused by external interference, and ensure the accuracy and quality of drilling.

[0032] In the specific operation process, other forms of the clamping part 203 structure may also be used, such as the bolt clamping clamping part 203 structure and the spring clamping clamping part 203 structure. The bolt clamping clamping part 203 structure can fix the clamping part 203 in the annular groove 301 by bolts. The advantage is that it is firmly fixed and not easy to loosen, and can withstand large external forces. However, the adjustment is relatively troublesome and requires the use of tools for operation; the spring clamping clamping part 203 structure uses the elastic force of the spring to clamp the clamping part 203 in the annular groove 301. The adjustment is relatively convenient, and the position can be adjusted by gently pressing or pulling. However, it may be easy to loosen when subjected to large external forces.

[0033] Compared with other forms of the clamping part 203 structure, the clamping part 203 structure of the current design has the advantages of being more convenient to adjust the position, and can be quickly adjusted on the construction site without the aid of complex tools. At the same time, the position adjustment range of the clamping part 203 in the annular groove 301 is large, which can meet more different support requirements. Moreover, this structural design is relatively simple and has high reliability, reducing the risk of failure caused by complex structures.

[0034] Furthermore, the clamping portion 203 has a through groove 204 , and also includes: an annular clamping strip 4 , which is disposed in the annular groove 301 and passes through the through groove 204 , and the clamping portion 203 is adjustable in position in the annular groove 301 through the annular clamping strip 4 .

[0035] In this embodiment, in order to further improve the tightness of the clamping part 203 in the annular groove 301, facilitate adjustment and fixation, and enhance the structural reliability, the annular clamping strip 4 is arranged in the annular groove 301 and penetrates the through groove 204 of the clamping part 203, so that the clamping part 203 can be adjusted in the annular groove 301. In actual operation, when the position of the base frame 201 needs to be adjusted, the operator can easily slide the clamping part 203 along the annular clamping strip 4 to quickly find a suitable position. This adjustment method is very convenient and does not require complicated operation steps, which greatly improves work efficiency. At the same time, the annular clamping strip 4 can play a good fixing role on the clamping part 203, effectively resist external forces, and prevent the clamping part 203 from escaping from the annular groove 301, thereby enhancing the reliability of the entire support mechanism.

[0036] Different drilling tasks may require different support positions and angles. Through the design of the annular clamping strip 4 and the through slot 204, the operator can flexibly adjust the position and angle of the base frame 201 according to the specific drilling requirements, thereby improving the adaptability of the drilling vehicle to different working scenarios. Whether under different geological conditions or under different drilling depth requirements, the best support effect can be achieved by adjusting the position of the clamping part 203 to ensure the smooth progress of the drilling operation.

[0037] Furthermore, the annular clip strip 4 is wavy, and the width of the through slot 204 is smaller than the width of the annular clip strip 4 at the wave crest position.

[0038] In this embodiment, the wave-shaped design of the annular clamping strip 4 and the characteristics that the width of the through slot 204 is smaller than the width of the wave crest position enable the clamping portion 203 to be firmly fixed on the annular clamping strip 4. During the operation of the drilling vehicle, even if it is subjected to strong vibration and external force impact, the clamping portion 203 will not easily fall off the annular clamping strip 4. At the same time, the wave-shaped annular clamping strip 4 can provide multiple different clamping positions, so that the clamping portion 203 can be positioned more accurately when adjusting the position.

[0039] Although there will be a certain resistance when the clamping part 203 is inserted into the annular clamping strip 4, this resistance does not affect the convenience of adjustment. On the contrary, it can prevent the clamping part 203 from accidentally sliding to a certain extent. When the position of the base frame 201 needs to be adjusted, the operator only needs to push the clamping part 203 hard, without the need to use additional tools or complicated operating steps, which greatly improves work efficiency.

[0040] Furthermore, the support member 2 further comprises: a slide rail 205 , which is slidably arranged on the base frame 201 along the generatrix direction of the supporting sleeve 3 , and the position-limiting support drill 202 is adjustable on the base frame 201 through the slide rail 205 .

[0041] In this embodiment, in actual application, the slide rail 205 is slidably set on the base frame 201 along the busbar direction of the support sleeve 3, so that the position adjustment of the limit support drill 202 is more flexible. On the one hand, by adjusting the position of the limit support drill 202 through the slide rail 205, different drilling requirements and working environments can be more accurately adapted. For example, under complex geological conditions, the position of the limit support drill 202 can be quickly adjusted according to actual conditions to ensure the best support effect on the drill rod part 1. On the other hand, the setting of the slide rail 205 improves the efficiency and convenience of adjustment. The operator does not need to perform complicated operations, but only needs to slide the limit support drill 202 along the slide rail 205 to complete the position adjustment, saving time and labor costs. At the same time, this design also enhances the stability and reliability of the entire support mechanism, ensuring that the drilling vehicle can operate stably during the drilling operation and improving the accuracy and quality of drilling.

[0042] Furthermore, there are three support members 2 , two position-limiting support drills 202 , and both sides of the slide rail 205 are provided with sliding holes 206 , and one position-limiting support drill 202 is slidably disposed in one sliding hole 206 .

[0043] In this embodiment, three support members 2 are used to fully support the drill rod portion 1. When the drill rod portion 1 is perpendicular to the drilling surface, the three support members 2 are evenly distributed around the drill rod portion 1 at intervals of 120 degrees. Otherwise, they are arranged at appropriate positions and angles.

[0044] Furthermore, sliding holes 206 are opened on both sides of the sliding rail 205 of each group of support members 2, that is, a total of six limit support drills 202 are equipped on a group of drill rod parts 1, and the limit support drills 202 are slidably connected with the support members 2 separately. This is because in order to ensure a more stable support effect, the depth of each group of limit support drills 202 drilling into the side wall may be different, and the same applies to the angle. Therefore, they are arranged in advance in the form of fasteners, etc., and this relative position can ensure a stable support effect, so as to ensure that each limit support drill 202 can be extended to an appropriate depth.

[0045] Furthermore, the position-limiting support drill 202 includes: a sliding portion 207 slidably disposed in the sliding hole 206 ; a drill head 208 , the drill head 208 being disposed at one end of the sliding portion 207 , the drill head 208 having a position-limiting support ring 209 , the position-limiting support ring 209 being used to abut against the drill wall to support the position-limiting support drill 202 .

[0046] In this embodiment, when the drilling vehicle performs drilling operations, the position of the base frame 201 on the support sleeve 3 and the position of the limit support drill 202 on the slide rail 205 of the base frame 201 are first adjusted according to actual conditions. After the position is determined, the drill rod portion 1 of the drilling vehicle starts to work and drills underground. As the drilling progresses, if the limit support drill 202 needs to play a role, the sliding portion 207 slides in the sliding hole 206 to push the drill head 208 toward the borehole wall. The limit support ring 209 of the drill head 208 abuts against the drill wall, providing a support point for the entire limit support drill 202, thereby supporting and guiding the drill rod portion 1 from different directions.

[0047] Among them, the limit support ring 209 can accurately abut the drill wall, providing a stable support point for the limit support drill 202. This design makes the support more accurate, can effectively reduce the shaking and deviation of the drill rod 1 during the drilling process, and improve the accuracy and quality of the drilling.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
