[0003] However, traditional rock drilling rigs often have many limitations when facing construction sites with different geological conditions. For example, in soft soil layers, their supporting structure cannot effectively achieve stable leveling, causing the drilling rig to shake easily during operation, affecting the rock drilling accuracy and efficiency. At the same time, it increases the workload and cost of pre-construction preparations, and requires a lot of manpower and material resources to level the site or build complex supporting devices. In hard soil or rock formations, the supporting components of traditional drilling rigs are difficult to embed firmly into the ground and cannot provide sufficient stability, which limits their ability to operate under such geological conditions.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Excellent site adaptability and efficient operation support:

[0020] The height-adjustable support leg of the present invention adopts an innovative structural design, which cleverly combines a connecting tube, a threaded lifting tube, an internally threaded tube, a conical drill bit, a rubber airbag and an anti-cutting pad. In actual application, when the drilling rig arrives at the construction site and faces a soft soil layer, the operator can drive the threaded lifting tube to rise and fall in the connecting tube by turning the first hand wheel, preliminarily adjust the horizontality of the base, and then turn the second hand wheel to lower the internally threaded tube, and use the conical drill bit at the bottom of the tube to drill a hole. Subsequently, the natural gas inflation pump inflates the rubber airbag through a rigid U-shaped air guide tube and an air guide hose, and the airbag expands outward through the airbag expansion opening, and is stably supported on the inner wall of the drill hole with the help of the protective effect of the anti-cutting pad, thereby achieving fast and stable support and Leveling; For hard soil or rock formations, you can first drill a hole with a handheld rock drill, and then put the internal threaded barrel into the preset hole and inflate it for support; this unique support and leveling system greatly expands the application scenarios of the drilling rig, enabling it to be quickly deployed and stably operated at construction sites with different geological conditions such as building foundation construction, mining and other types of rock drilling projects, effectively reducing construction difficulties caused by site conditions, significantly improving construction efficiency, and reducing the manpower, material and time costs of pre-construction preparations, which effectively improves the practicability and market competitiveness of the product in complex and changeable construction environments, and provides a solid and reliable basic guarantee for the efficient development of rock drilling operations.

[0021] 2. Comprehensive advantages of accurate and efficient rock drilling operations:

[0022] The present invention adopts a feed guide rail adjustment system in which a multi-stage hydraulic cylinder and a multi-section telescopic rod work in coordination, and a unique design equipped with an intelligent inflation control support system, which brings significant comprehensive advantages to rock drilling operations; in actual operation, the multi-stage hydraulic cylinder, with its powerful power output and large stroke range, can quickly push the feed guide rail to make large-scale angle adjustments and position movements, meeting the initial setting requirements for feed direction and depth in different rock drilling operation scenarios. For example, when facing large-scale rock mining operations, the drill bit can be quickly positioned to the approximate operating area; and the multi-section telescopic rod, with its precise locking mechanism, can perform high-precision fine-tuning on the feed guide rail, further accurately control the rock drilling position and angle, and ensure that the drill bit can accurately act on the target rock part; At the same time, with the stable support of the rubber airbag in the height-adjusting support leg, the shaking of the natural gas-driven integrated full-hydraulic rock drilling rig during operation is effectively avoided; this innovative combined adjustment method greatly improves the drilling quality and greatly reduces the problems of drilling deviation and incomplete rock crushing caused by inaccurate positioning or shaking of the natural gas-driven integrated full-hydraulic rock drilling rig. It not only improves the quality of a single rock drilling operation, but also reduces the number of repeated operations caused by quality problems, thereby significantly reducing construction costs and time costs. Compared with traditional drilling rigs with a single adjustment method, the present invention shows obvious technical advantages in the accuracy, efficiency and economy of rock drilling operations, and provides a more reliable and efficient solution for modern rock drilling projects.

[0023] 3. Stable and reliable operating performance:

[0024] The densely arranged damping shock absorbers, buffer rubber pads and rubber airbags in the height-adjusting support legs can effectively reduce the damage to the natural gas-driven integrated full-hydraulic rock drilling rig caused by vibration and impact force during the rock drilling process, extend the service life of the invention, and reduce the maintenance frequency and cost of the invention; the stable operating state can also improve the working comfort and safety of the operator, reduce the safety accidents caused by failure or excessive vibration of the natural gas-driven integrated full-hydraulic rock drilling rig, ensure the continuity and stability of the construction process, and further enhance the practicability of the product in actual engineering applications.

[0025] 4. Reduced energy costs:

[0026] Using natural gas to drive hydraulic pumps to power the drilling rig not only reduces energy costs but also reduces environmental pollution compared to traditional fuel or electric drive methods. This is in line with the trend of modern industrial demand for clean energy and is a novel attempt at a rock drilling rig power system, providing a new energy utilization idea for industry development.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figure 1-Figure 10 As shown, an integrated full-hydraulic rock drilling rig driven by natural gas includes a base 1 and a feed guide rail 2 installed on the base 1. A natural gas engine 101 and a hydraulic pump 102 are fixedly installed on the base 1. The natural gas engine 101 is connected to the hydraulic pump 102 through a specific transmission mechanism. The natural gas engine 101 converts the chemical energy of natural gas into mechanical energy, drives the hydraulic pump 102 to operate, and provides a power source for the hydraulic system of the entire integrated full-hydraulic rock drilling rig driven by natural gas.

[0040] refer to Figure 1 It can be seen that two forklift connection ports 103 are provided on one side of the base 1. The cross-section of the base 1 is rectangular. A notch for passing the end of the feed guide rail 2 is provided on one side of the base 1. Four height-adjusting support legs 3 are evenly and vertically installed on the four edges of the base 1. An inflation device 4 connected to the height-adjusting support legs 3 is also fixedly installed on the base 1.

[0041] refer to Figure 2-Figure 5It can be seen that the height-adjusting support leg 3 includes a connecting tube 301, a threaded lifting tube 302, an internally threaded tube 304 and a rubber airbag 305. The connecting tube 301 is fixedly connected to the base 1. The outer thread of the threaded lifting tube 302 is installed in the connecting tube 301. The lower end of the threaded lifting tube 302 is coaxially fixedly installed with an annular support plate 303. The top of the threaded lifting tube 302 is coaxially fixedly installed with a first hand wheel 306. The outer thread of the internally threaded tube 304 is installed in the threaded lifting tube 302. The internally threaded tube 304 is installed in the threaded lifting tube 302. An airbag installation cavity 307 is provided at the lower end of the tube 304, and the outer wall of the rubber airbag 305 is fittedly installed on the inner wall of the airbag installation cavity 307 at the lower end of the internal threaded tube 304, and the periphery of the airbag installation cavity 307 is evenly connected and provided with more than two airbag expansion openings 308. A second hand wheel 309 is fixedly installed on the upper end of the internal threaded tube 304, and a conical drill bit 315 is coaxially fixedly connected to the lower bottom surface of the internal threaded tube 304, and the conical drill bit 315 is arranged below the airbag installation cavity 307.

[0042] refer to Figure 3 and Figure 4 It can be seen that a plurality of radial round rods 316 are fixedly installed on the outer rings of the first hand wheel 306 and the second hand wheel 309, so that the steel pipe can be sleeved on the radial round rods 316, and the steel pipe can be used to more labor-savingly rotate the first hand wheel 306 or the second hand wheel 309. By rotating the first hand wheel 306 clockwise or counterclockwise, the threaded lifting cylinder 302 in the support leg 3 at the four corners of the base 1 can be driven to be raised and lowered, so as to adjust the horizontality of the four corners of the base 1. By rotating the second hand wheel 309 clockwise or counterclockwise, the internal threaded cylinder 304 can be driven to be spirally lifted along the inner cavity of the threaded lifting cylinder 302, so as to adjust the height of the internal threaded cylinder 304 in the threaded lifting cylinder 302.

[0043] refer to Figure 3 It can be seen that a plurality of anti-cut pads 314 are attached to the outer wall of the rubber airbag 305 . The plurality of anti-cut pads 314 are respectively arranged on the outer wall of the rubber airbag 305 at a plurality of airbag expansion openings 308 . The anti-cut pads 314 are preferably made of polyurethane material.

[0044] refer to Figure 1 It can be seen that the inflation device 4 includes a natural gas inflation pump 401 and a rigid U-shaped air guide tube 402, both of which are fixedly installed on the base 1, the air inlet of the rigid U-shaped air guide tube 402 and the air outlet of the natural gas inflation pump 401 are interconnected, and the inner cavity of the rigid U-shaped air guide tube 402 is respectively interconnected with the inner cavities of the rubber air bags 305 in several rigid U-shaped air guide tubes 402.

[0045] refer to Figure 3 and Figure 4It can be seen that the top of the rubber airbag 305 is fixedly connected to a vertical pipe 310, and the top of the vertical pipe 310 is fixedly connected to a one-way valve 312. The one-way valve 312 is mainly used for the natural gas inflation pump 401 to unidirectionally inflate the rubber airbag 305. The air inlet of the one-way valve 312 is connected to an air hose 313 through a rotating joint. The top of the air hose 313 is fixedly connected to the bottom of the rigid U-shaped air pipe 402. The upper end of the vertical pipe 310 is vertically connected to an exhaust valve 311, and the exhaust valve 311 is arranged below the one-way valve 312. When it is necessary to fold the integrated full-hydraulic rock drilling rig driven by natural gas or adjust the support position of the integrated full-hydraulic rock drilling rig driven by natural gas, the gas in the rubber airbag 305 can be discharged through the exhaust valve 311, which is convenient for operation.

[0046] In this embodiment, the workflow of raising the supporting leg 3 is as follows:

[0047] When the natural gas-driven integrated fully hydraulic rock drilling rig arrives at the work site, a suitable support method is first selected according to the ground conditions under the base 1.

[0048] If the soil is relatively soft, the height of the threaded lifting cylinder 302 is adjusted by turning the first hand wheel 306 to preliminarily adjust the horizontality of the base 1, and then the second hand wheel 309 is turned to lower the internal threaded cylinder 304, and a hole is drilled using the conical drill bit 315. Then the natural gas inflation pump 401 inflates the rubber airbag 305 through the rigid U-shaped air guide tube 402, the air guide hose 313, and the vertical pipe 310, so that it expands and supports on the inner wall of the drill hole to achieve stable support, and the anti-cut pad 314 is used to prevent the airbag from being cut.

[0049] If it is harder soil or rock, first use a handheld rock drill to drill a hole, then put the internal threaded tube 304 into the preset hole, and then perform the inflation operation to ensure the stable support of the base 1. When the above-mentioned integrated full-hydraulic rock drilling rig driven by natural gas generates vibration during operation, the rubber airbag 305 itself has elasticity, which can buffer and absorb part of the vibration from the ground, just like an elastic pad. For example, when the impact force generated during the rock drilling process is transmitted to the drilling rig base 1, the rubber airbag 305 can disperse and weaken these impact forces through its own elastic deformation, thereby reducing the vibration amplitude transmitted to the base 1, and the support system composed of the rubber airbag 305 and the inflation device 4 can adaptively adjust the support state according to the ground conditions, and has a certain buffering capacity for vibrations of different frequencies and intensities. The auxiliary damping shock absorber 8 and the buffer rubber pad 9 and other components work together to further improve the shock absorption effect of the entire drilling rig.

[0050] refer to Figure 6 and Figure 7It can be seen that an articulated seat 5 is arranged between the base 1 and the feed guide rail 2, and the articulated seat 5 includes a articulated seat plate 501, two first articulated blocks 502 and a second articulated block 503.

The ends of the telescopic ends of the two multi-stage hydraulic cylinders 6 are respectively rotatably installed on both sides of the other end of the feed guide rail 2. A stable triangular structure is formed between the multi-stage hydraulic cylinder 6, the articulated seat 5 and the feed guide rail 2, and the multi-stage hydraulic cylinder 6 can achieve self-locking through the oil circuit.

The lengths of the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705, the fourth telescopic rod 706, and the fifth telescopic rod 707 in the multi-section telescopic rod 7 are mainly fixed by four locking mechanisms.

[0052] refer to Fig. 9 and Fig.10It can be seen that the locking mechanism includes a screw 715, a circular slider 709 and two annular wear-resistant rubber blocks 710. The outer walls of the circular sliders 709 and the annular wear-resistant rubber blocks 710 in the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705 and the fourth telescopic rod 706 are respectively interlocked with the inner cavities of the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705 and the fourth telescopic rod 706, that is, the four circular sliders 709 and the four annular wear-resistant rubber blocks 710 in the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705 and the fourth telescopic rod 706 are different in size.

The circular slider 709 is coaxially telescopically installed in the first telescopic rod 703 or the second telescopic rod 704 or the third telescopic rod 705 or the fourth telescopic rod 706, and the inner walls of the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705, and the fourth telescopic rod 706 are all provided with a sliding groove 713. The pitch of the internal thread of the circular slider 709 and the internal thread of the pitch-adjusting nut 702 are the same, and the inner walls of the first telescopic rod 703, the second telescopic rod 704, the third telescopic rod 705, and the fourth telescopic rod 706 are fixedly connected with a plurality of equidistantly arranged anti-slip grooves 714.

[0053] In this embodiment, the locking process of the length of the multi-section telescopic rod 7 is as follows:

[0054] First, fix the fourth telescopic rod 706, rotate the fifth telescopic rod 707, and push the annular wear-resistant rubber block 710 close to the guide bar 712 by the limit block 711 in the locking mechanism at the head end of the fifth telescopic rod 707, that is, the total length between the fourth telescopic rod 706 and the fifth telescopic rod 707 becomes longer, so that the outer ring of the annular wear-resistant rubber block 710 is deformed and squeezed and fixed on the inner wall of the fourth telescopic rod 706;

When the first telescopic rod 703 is rotated, one end of the first telescopic rod 703 drives the circular slider 709 therein to rotate away from the second telescopic rod 704, and the other end of the first telescopic rod 703 is screwed close to the bottom cylinder 701. The length of the contraction of the pitch-adjusting nut 702 is used to compensate for the increased length between the first telescopic rod 703 and the second telescopic rod 704.

[0057] As can be seen from the above, the multi-stage hydraulic cylinder 6 and the multi-section telescopic rod 7 act together on the feed guide rail 2. The multi-stage hydraulic cylinder 6 provides the main thrust and pulling force to achieve a large angle adjustment and position movement of the feed guide rail 2. The multi-section telescopic rod 7 plays a role of auxiliary support and fine-tuning. Through its unique locking mechanism, the length of each section of the telescopic rod can be accurately fixed, further enhancing the stability and positioning accuracy of the feed guide rail 2 to meet the needs of different rock drilling operation scenarios.

The skirt 901 in the buffer rubber pad 9 is surrounded and arranged on the outer wall of the hinge seat plate 501 for dust prevention. The hinge seat plate 501 in the hinge seat 5 is connected to the base 1 through the damping shock absorber 8 and the buffer rubber pad 9, which effectively reduces the impact force and vibration transmission of the feed guide rail 2 to the base 1 during the rock drilling process, thereby ensuring the stability of the entire integrated full-hydraulic rock drilling rig driven by natural gas.

[0059] It should be added that the high-pressure oil output by the hydraulic pump 102 is connected to the multi-stage hydraulic cylinder 6 through a series of control valves and pipelines. By controlling the opening and closing of the hydraulic valves and the flow direction and flow of the oil, the telescopic action of the multi-stage hydraulic cylinder 6 is realized, thereby accurately controlling the angle and position of the feed guide rail 2 to meet the different needs of rock drilling operations. For example, when performing rock drilling operations, according to the hardness of the rock and the depth requirements of the drilling hole, the hydraulic pump 102 is driven by the natural gas engine 101 to provide the multi-stage hydraulic cylinder 6 with appropriate pressure and flow, so that it can stably push the feed guide rail 2 to ensure the efficiency and accuracy of the rock drilling process. The natural gas inflation pump 401 is equipped with a pressure sensor and a flow controller, which can monitor and control the pressure and flow of the rubber airbag 305 in real time to ensure that the rubber airbag 305 is evenly and stably inflated to achieve the best support effect, while avoiding damage to the rubber airbag 305 caused by excessive inflation. The above-mentioned pressure sensor and flow controller are not shown in the figure.
