Description

Technical Field

[0001] This invention relates to the field of rock drilling technology, specifically to a rock drilling device for engineering geological exploration. Background Technology

[0002] Engineering geological investigation is a geological survey and research work conducted to identify the geological factors affecting engineering structures. The geological factors to be investigated include geological structure or geological formation: landforms, hydrogeological conditions, physical and mechanical properties of soil and rock, natural (physical) geological phenomena, and natural building materials. After identifying the engineering geological conditions, it is necessary to predict the mode, characteristics, and scale of the interaction between the engineering structure and the geological environment (i.e., engineering geological processes) based on the structural and operational characteristics of the designed structure, and to make a correct evaluation, providing a basis for determining protective measures to ensure the stability and normal use of the structure.

[0003] Existing rock drilling equipment for engineering geological exploration typically sprays water to suppress dust during drilling. However, the amount of water sprayed cannot be flexibly adjusted according to the working conditions, which easily leads to the waste of water resources. Furthermore, the water outlet is directly exposed to the outside and is easily blocked by flying rock cuttings and dust, affecting normal water spraying and making it impractical. Therefore, it is necessary to provide a rock drilling equipment for engineering geological exploration to solve the above-mentioned technical problems. Summary of the Invention

The bottoms of the two electric telescopic rods extend through the top wall of the collar receiving body and are fixedly connected to the top of the hollow inner ring.

[0008] Preferably, a water guide pipe is fixedly provided on the top left side of the receiving collar body, and the top left side of the hollow inner ring is fixedly connected to the top wall of the left inner cavity of the receiving collar body through a telescopic hose, and the water guide pipe, the telescopic hose and the interior of the hollow inner ring are in a connected state.

[0013] Beneficial effects

[0014] This invention provides a rock drilling device for engineering geological exploration. Compared with the prior art, it has the following advantages:

[0015] (1) The rock drilling equipment for geological exploration in this project has a hollow inner ring penetrating inside the receiving ring body. Electric telescopic rods are fixedly installed on the top left and right sides of the receiving ring body. The bottom of the two electric telescopic rods penetrates the top wall of the receiving ring body and is fixedly connected to the top of the hollow inner ring. A water guide pipe is fixedly installed on the top left side of the receiving ring body. The top left side of the hollow inner ring is fixedly connected to the top wall of the left inner cavity of the receiving ring body through a telescopic hose. The water guide pipe, telescopic hose and the interior of the hollow inner ring are in a connected state. Through the cooperation between the receiving ring body, the hollow inner ring, the electric telescopic rod and the telescopic hose, the horizontal height of the hollow inner ring can be flexibly adjusted according to the working conditions, thereby adjusting the number of water outlet short pipes exposed. When there is a lot of dust, the number of water outlet short pipes exposed is increased, thereby increasing the amount of water sprayed. When there is little dust, the number of water outlet short pipes exposed is reduced, thereby reducing the amount of water sprayed, thus avoiding the waste of water resources.

[0016] (2) The rock drilling equipment for geological exploration in this project is fixedly connected to the upper part of the left and right side walls of the hollow inner ring by two limiting sliders respectively. A barrier ring is fixedly installed between the upper and lower walls of the inner cavity of the hollow inner ring. Several water outlet short pipes are evenly fixedly installed between the barrier ring and the inner wall of the hollow inner ring. A support rod is fixedly installed between the upper and lower walls on the side of the water outlet short pipe near the barrier ring. A shaft is rotatably installed in the middle of the support rod. An impeller is fixedly installed at the end of the shaft near the barrier ring, and a spiral dredging rod is fixedly installed at the end of the shaft away from the impeller. Through the mutual cooperation between the barrier ring, the water outlet short pipe, the impeller, and the spiral dredging rod, the impeller will be driven to rotate under the impact of the water flow, which will in turn cause the spiral dredging rod to rotate. During the rotation, the spiral dredging rod can dredge the inside of the water outlet short pipe, preventing external flying rock chips and dust from clogging the water outlet short pipe and ensuring the normal operation of water spraying.

[0017] (3) The rock drilling equipment for geological exploration in this project has a cleaning scraper fixedly installed at the bottom of the receiving ring body. The inner cavity of the receiving ring body has a limit groove on both the left and right sides. The two limit grooves are equipped with limit sliders. The cleaning scraper can clean the part of the hollow inner ring in time. The cleaning is timely. The structure is simple but the function is powerful. When water is not sprayed, the hollow inner ring can re-enter the receiving ring body to protect the outside of the hollow inner ring. It is highly practical. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides two technical solutions:

[0026] like Figure 1 The first embodiment is shown: a rock drilling device for engineering geological exploration, including a plurality of drilling rig anti-slip bases 1, a connecting plate 2 fixedly installed on the top of each of the plurality of drilling rig anti-slip bases 1, a functional collar assembly 3 fixedly installed between the plurality of connecting plates 2, a limiting long slide rod 4 fixedly installed on the top of each connecting plate 2, a connecting reinforcement frame 5 fixedly installed between the tops of the plurality of limiting long slide rods 4, a bearing platform 6 slidably sleeved between the outer sides of the plurality of limiting long slide rods 4, a first servo motor 7 fixedly installed on the top of the bearing platform 6, a spiral drill rod 8 for drilling into the rock strata for engineering geological exploration fixedly installed through the bottom of the bearing platform 6 at the output end of the first servo motor 7, a second servo motor 9 fixedly installed on the top right side of the bearing platform 6, a spur gear 10 fixedly installed at the output end of the second servo motor 9, and a rack 11 fixedly installed between the right side of the functional collar assembly 3 and the right side of the connecting reinforcement frame 5.

[0027] By cooperating with the housing collar body 31, the hollow inner ring 32, the electric telescopic rod 33, and the telescopic hose 35, the horizontal height of the hollow inner ring 32 can be flexibly adjusted according to the working conditions, thereby adjusting the number of exposed water outlet short pipes 310. When there is a lot of dust, the number of exposed water outlet short pipes 310 is increased, thereby increasing the amount of water sprayed. When there is less dust, the number of exposed water outlet short pipes 310 is reduced, thereby reducing the amount of water sprayed, thus avoiding the waste of water resources.

[0028] like Figure 2-5 The second embodiment is shown, the main difference from the first embodiment being: a rock drilling device for engineering geological exploration, wherein the bottom of the spiral drill rod 8 passes through a functional collar assembly 3, the right side of the spur gear 10 meshes with the left side of the rack 11, the functional collar assembly 3 includes a collar receiving body 31, a hollow inner ring 32 passing through the interior of the collar receiving body 31, electric telescopic rods 33 fixedly installed on the left and right sides of the top of the collar receiving body 31, the bottom of the two electric telescopic rods 33 passing through the top wall of the collar receiving body 31 and fixedly connected to the top of the hollow inner ring 32, a water guide pipe 34 fixedly installed on the top left side of the collar receiving body 31, and the top left side of the hollow inner ring 32 being fixedly connected to the top wall of the left inner cavity of the collar receiving body 31 by a telescopic hose 35, and the water guide pipe 34, the telescopic hose 35, and the interior of the hollow inner ring 32 are connected. In the connected state, a cleaning scraper ring 36 is fixedly installed at the bottom of the receiving collar body 31. Limiting grooves 37 are opened on both the left and right sides of the inner cavity of the receiving collar body 31. Limiting sliders 38 are slidably installed inside the two limiting grooves 37. The two limiting sliders 38 are fixedly connected to the upper part of the left and right side walls of the hollow inner ring 32 respectively. A barrier ring 39 is fixedly installed between the upper and lower walls of the inner cavity of the hollow inner ring 32. Several water outlet short pipes 310 are evenly fixedly inserted between the barrier ring 39 and the inner wall of the hollow inner ring 32. A support rod 311 is fixedly installed between the upper and lower walls on the side of each water outlet short pipe 310 near the barrier ring 39. A shaft 312 is rotatably inserted through the middle of the support rod 311. An impeller 313 is fixedly installed at the end of the shaft 312 near the barrier ring 39. A spiral unblocking rod 314 is fixedly installed at the end of the shaft 312 away from the impeller 313.

[0029] Through the cooperation of the blocking ring 39, the outlet short pipe 310, the impeller 313, and the spiral unblocking rod 314, the impeller 313 will rotate under the impact of the water flow, which in turn will cause the spiral unblocking rod 314 to rotate. During the rotation, the spiral unblocking rod 314 can unclog the inside of the outlet short pipe 310, preventing external flying rock debris and dust from clogging the outlet short pipe 310 and ensuring the normal operation of water spraying. The cleaning scraper ring 36 can promptly scrape the part passed by the hollow inner ring 32, which is relatively timely. The structure is simple but powerful. When water spraying is not needed, the hollow inner ring 32 can re-enter the receiving ring body 31 to protect the outside of the hollow inner ring 32. It is highly practical.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] In use, place the equipment at the work site, then start the first servo motor 7 and the second servo motor 9. The first servo motor 7 drives the spiral drill rod 8 to rotate, and the second servo motor 9 drives the spur gear 10 to rotate. Since the spur gear 10 meshes with the rack 11, the spur gear 10 moves downward along the rack 11 during rotation, and the spiral drill rod 8 moves downward while rotating, drilling into the rock strata below. Adjust the horizontal height of the hollow inner ring 32 according to the drilling progress, i.e., adjust the number of exposed water outlet pipes 310. When there is a lot of dust generated during drilling, increase the number of exposed water outlet pipes 310. During the process, activate the electric telescopic rod 33 to push the hollow inner ring 32 downward a suitable distance. Simultaneously, the limit slider 38 slides downward along the limit groove 37, making the water outlet pipes 310 exposed to a suitable extent. Start the external water pump to draw external water into the water guide pipe 34, and then the water enters the hollow inner ring 32 through the telescopic hose 35, finally spraying out through the various water outlet pipes 310 connected to the outside, thereby increasing... The large volume of water sprayed out during the process causes the impeller 313 to rotate under the impact of the water flow, which in turn causes the spiral unblocking rod 314 to rotate. During the rotation of the spiral unblocking rod 314, the internal part of the water outlet short pipe 310 is unblocked, while preventing external flying rock debris and dust from clogging the water outlet short pipe 310. When the dust generated during drilling is small, the amount of water outlet short pipe 310 exposed is reduced, and the electric telescopic rod 33 is activated to lift the hollow inner ring 32 to a suitable height, allowing part of the water outlet short pipe 310 to enter the receiving collar. Inside the main body 31, the receiving collar body 31 simultaneously seals the internal water outlet short pipe 310, thereby reducing the amount of water sprayed out and avoiding waste of water resources. During the upward movement of the hollow inner ring 32, the cleaning scraper ring 36 can promptly scrape the part that the hollow inner ring 32 passes through, removing the dust adhering to the part that the hollow inner ring 32 passes through. When dust suppression is not required, the electric telescopic rod 33 is activated to completely pull the hollow inner ring 32 into the receiving collar body 31, using the receiving collar body 31 to protect the hollow inner ring 32.
