Description

Technical Field

[0001] This utility model belongs to the technical field of gangue mountain management equipment, specifically relating to a drilling device for installing finned heat pipes in gangue mountains. Background Technology

[0002] The problem of heat storage and spontaneous combustion in coal gangue piles is very common, which not only causes economic losses but also damages the ecosystem. Heat pipe cooling technology, as a new technology for controlling spontaneous combustion in coal gangue piles, has the advantages of low cost, good environmental protection and good tolerance. The evaporation section of the heat pipe is placed in the high-temperature area inside the coal gangue pile, and the condensation section is welded with fins and placed in the air. Heat is introduced into the heat pipe through the shell, where the working fluid evaporates at high temperature. The working fluid gas moves the heat upward to the condensation section of the heat pipe, where it liquefies under the low temperature and flows back to the evaporation section. The working fluid continuously undergoes phase change and circulates inside the heat pipe, achieving the transfer of heat from the self-igniting coal gangue pile. To achieve this effect, a specified number and spacing of heat pipes need to be installed in the coal gangue pile. This requires drilling equipment to drill installation holes for laying the heat pipes. The commonly used drilling equipment in gangue piles is the tracked auger drill. Tracked auger drills are often used for large-area drilling operations. For single or small-scale drilling, smaller drilling equipment is more convenient. Furthermore, smaller drilling equipment is more flexible in construction locations with limited space because it is smaller in size than tracked auger drills.

[0003] The existing drilling process mainly relies on workers to apply pressure by hand using the equipment based on their experience, which makes it difficult to ensure the smoothness of the auger rod advance. The entire drilling operation, from advance to retreat, depends entirely on the physical strength of the workers. Operators need to be close to the drilling point. The composition of the gangue mountain is complex, and the flying debris generated during the drilling process poses a continuous safety threat to personnel, making it highly dangerous.

[0004] Therefore, there is an urgent need for a drilling device for installing finned heat pipes in gangue piles that can overcome the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling device for installing finned heat pipes in gangue mountains, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for installing finned heat pipes in a gangue mountain, comprising a handcart, a gasoline engine, a spiral drill rod, a slide rail, and a slider platform, wherein the top of the handcart is fixedly connected to the slide rail, the outer surface of the slide rail is slidably connected to the slider platform, the top of the slider platform is fixedly connected to the gasoline engine, and the output end of the gasoline engine is connected to the spiral drill rod through a pin; The slide block platform is equipped with a propulsion mechanism. The propulsion mechanism is fixedly connected to the side of the slide block platform away from the auger rod. Several insertion holes are provided at the front and rear of the handcart. A depth adjustment component that limits the horizontal sliding position of the slide block platform on the outer surface of the slide rail is inserted into the insertion holes. The propulsion mechanism includes a support plate fixedly connected to one side of the slider platform. A support rod is fixedly connected to the top of the support plate, and a baffle is fixedly connected to the other end of the support rod. Hollow cylinders are fixedly connected to the front and rear of the baffle, and rubber filler blocks are fixedly connected to the inner wall of the hollow cylinders. A telescopic push rod is fixedly connected to the side of the support plate opposite to the slider platform.

[0007] Using the above scheme, the sliding block platform is pushed horizontally on the outer surface of the slide rail by the propulsion mechanism, and the rotating auger rod is pushed into the gangue pile in a smooth and controllable manner to carry out drilling operations at the current position. At the same time, the propulsion mechanism can keep a certain distance between the workers and the drilling site, so as to avoid the flying debris generated during the drilling process from splashing onto the workers and reducing the safety hazards caused by continuous pushing by workers. The depth adjustment component can precisely control the drilling depth by limiting the sliding distance of the sliding block platform on the slide rail, ensuring that the heat pipe can be installed in the predetermined position and avoiding being too deep or too shallow.

[0008] In a preferred embodiment, the top of the rubber filler block is provided with a plurality of annularly distributed mounting holes, and the bottom of the hollow cylinder abuts against the top of the slider platform.

[0009] Using the above scheme, the heat pipe is usually designed in sections for easy transportation and handling. During operation, it can be moved by the casters on the bottom of the trolley. When working outdoors, the sections of the heat pipe can be inserted into multiple mounting holes, making it more convenient to carry the heat pipe. When drilling is finished and the heat pipe needs to be installed, the sections of the heat pipe placed in the mounting holes can be taken out and assembled. The mounting holes made of rubber are deformable and can accommodate heat pipes of more diameters. The slider platform provides support for the hollow cylinder.

[0010] In a preferred embodiment, the telescopic push rod includes an internally threaded tube fixedly connected to one side of the support plate, an externally threaded tube one end threadedly connected to the end of the internally threaded tube away from the support plate, an extension tube one end fixedly connected to the other end of the externally threaded tube, an externally threaded tube two end fixedly connected to the other end of the extension tube, and a handle fixedly connected to the other end of the externally threaded tube two.

[0011] Using the above solution, the telescopic push rod can adjust its length to meet the length requirements in drilling operations, allowing workers to continuously push the auger drill rod to drill into the gangue pile without moving their own position. At the same time, through the threaded connection, the extension tube can be retracted into the internal threaded tube when not in operation, reducing the amount of external space occupied.

[0012] In a preferred embodiment, the outer diameter of the internally threaded tube is the same as the outer diameter of the grip rod, and the external threads of both the first and second externally threaded tubes are adapted to the internal threads of the internally threaded tube.

[0013] Using the above scheme, both external threaded tube one and external threaded tube two can be threadedly connected to internal threaded tube. When external threaded tube one is threadedly connected to internal threaded tube, the extension tube is on the outside and is used to extend the length of the telescopic push rod. When external threaded tube two is threadedly connected to internal threaded tube, the extension tube can be retracted into internal threaded tube. The outer diameter of the extension tube is smaller than the inner diameter of internal threaded tube. When external threaded tube one is threadedly separated from internal threaded tube, the extension tube can slide into internal threaded tube for retraction.

[0014] In a preferred embodiment, the depth adjustment component includes a locking block with a concave groove at the rear and a damping shaft fixedly connected to the top of the locking block. A stop bar is fixedly connected to the outer surface of the damping shaft. A movable groove is provided on one side of the top of the locking block, and a limiting square plate is fixedly connected inside the movable groove. A through hole is provided at the front of the locking block, and a pin is inserted into the through hole.

[0015] Using the above scheme, the locking block is fixed to the handcart by a pin, and the stop bar is rotated to the top of the slide rail by a damping shaft to block the slider platform sliding on the outer surface of the slide rail. The sliding of the slider platform can be restricted according to the drilling depth requirements, and the limiting square plate is used to limit the position of the stop bar.

[0016] In a preferred embodiment, the pin passes through the perforation of the locking block and extends into the handcart's insertion hole, and one side of the limiting square plate abuts against one side of the stop bar.

[0017] Using the above solution, the pin passes through the locking block and extends into the handcart's insertion hole to fix the position of the depth adjustment component, and the limiting square plate acts as a stop for the stop bar.

[0018] In a preferred embodiment, the limiting square plate includes a spring, one end of which is fixedly connected to the bottom of the movable groove of the limiting square plate, and the other end of which is fixedly connected to the plate body.

[0019] Using the above solution, the spring force pushes the limiting square plate to block the stop bar. When it is necessary to adjust the angle of the stop bar, simply press the limiting square plate to compress the spring, so that the height of the limiting square plate is lower than the stop bar, and then the stop bar can be rotated. The operation is convenient.

[0020] Compared with the prior art, the beneficial effects of this utility model are: The sliding block platform is propelled horizontally on the outer surface of the slide rail by the propulsion mechanism, smoothly and controllably pushing the rotating auger rod into the rock pile for drilling operations at the current location. Simultaneously, the propulsion mechanism ensures a safe distance between the worker and the drilling site, preventing flying debris from hitting the worker and reducing safety hazards caused by continuous pushing. Before use, according to the operator's habits and work location, the external threaded tube is screwed into the internal threaded tube via the threaded connection, extending the extension tube to a suitable length for comfortable operation. When transporting or storing the equipment, the telescopic push rod can be fully screwed into the retracted state, reducing space occupation and offering high flexibility.

[0021] The depth adjustment component enables precise, reliable, and rapid setting of drilling depth. The combination of pin positioning and stop lever limiting results in a simple structure with strong anti-interference capabilities. During operation, simply selecting the insertion hole, inserting the pin, and lowering the stop lever completes the depth setting. The limiting square plate automatically locks the stop lever under spring action, ensuring reliable limiting. This design guarantees the consistency of heat pipe mounting hole depth, ensuring that the evaporation sections of all heat pipes accurately reach the predetermined heat-damaging zone, significantly improving heat pipe installation accuracy.

[0024] Please see Figure 1-5This utility model provides a drilling device for installing finned heat pipes in a gangue mountain, including a handcart 1, a gasoline engine 3, a spiral drill rod 4, a slide rail 6 and a slider platform 7. The top of the handcart 1 is fixedly connected to the slide rail 6, the outer surface of the slide rail 6 is slidably connected to the slider platform 7, the top of the slider platform 7 is fixedly connected to the gasoline engine 3, and the output end of the gasoline engine 3 is connected to the spiral drill rod 4 through a pin. The slide block platform 7 is fixedly connected to the propulsion mechanism 2 on the side away from the auger rod 4. Several insertion holes are opened at the front and rear of the handcart 1. A depth adjustment component 5, which restricts the horizontal sliding position of the slide block platform 7 on the outer surface of the slide rail 6, is inserted into the insertion holes. The propulsion mechanism 2 includes a support plate 25 fixedly connected to one side of the slider platform 7. One end of a support rod 24 is fixedly connected to the top of the support plate 25, and a baffle 23 is fixedly connected to the other end of the support rod 24. Hollow cylinders 21 are fixedly connected to both the front and rear parts of the baffle 23. Rubber filler blocks 22 are fixedly connected to the inner wall of the hollow cylinder 21. A telescopic push rod 26 is fixedly connected to the side of the support plate 25 opposite to the slider platform 7. The propulsion mechanism 2 pushes the slider platform 7 horizontally across the outer surface of the slide rail 6, smoothly and controllably pushing the rotating auger rod 4 into the waste rock pile for drilling operations. Simultaneously, the propulsion mechanism 2 maintains a safe distance between the worker and the drilling site, preventing flying debris from hitting them and reducing safety hazards associated with continuous pushing. The depth adjustment component 5 precisely controls the drilling depth by limiting the sliding distance of the slider platform 7 on the slide rail 6, ensuring the heat pipe can be installed in the predetermined position. To avoid drilling too deep or too shallow, stand the device upright with the auger rod 4 facing the ground. Vertical drilling can be performed using the auger rod 4. This device has multiple drilling modes. In normal operation, it is in horizontal drilling mode, which makes it easier to move the device. If the heat pipe to be installed is long and requires a deep drilling depth, pre-drilling can be performed using this device. That is, a specified number of marker holes are drilled at designated locations and intervals. Subsequently, workers can quickly identify the location for drilling using the marker holes, and then drill deeper holes based on the existing holes to meet the installation requirements of heat pipes of different depths.

[0025] The top of the rubber filler block 22 is provided with multiple annularly distributed mounting holes, and the bottom of the hollow cylinder 21 abuts against the top of the slider platform 7. Heat pipes are typically designed in segments for easy transport and handling. During operation, they are moved using the casters on the bottom of the trolley 1. When working outdoors, the segmented heat pipes can be inserted into multiple mounting holes, making it more convenient to carry them. When drilling is complete and the heat pipes need to be installed, the segmented heat pipes placed in the mounting holes can be removed and assembled. The mounting holes, made of rubber, are deformable and can accommodate heat pipes of various diameters. The slider platform 7 provides support for the hollow cylinder 21.

[0026] The telescopic push rod 26 includes an internally threaded tube 261 fixedly connected to one side of the support plate 25. The end of the internally threaded tube 261 away from the support plate 25 is threadedly connected to one end of an externally threaded tube 262. The other end of the externally threaded tube 262 is fixedly connected to one end of an extension tube 263. The other end of the extension tube 263 is fixedly connected to one end of an externally threaded tube 264. The other end of the externally threaded tube 264 is fixedly connected to a handle 265. The telescopic push rod 26 can adjust its length to meet the length requirements in drilling operations, allowing the operator to continuously push the auger drill rod 4 to drill the gangue mountain without moving its own position. At the same time, through the threaded connection, the extension tube 263 can be retracted into the internal threaded tube 261 when not in operation, reducing the external space occupied.

[0027] The outer diameter of the internally threaded tube 261 is the same as the outer diameter of the handle 265. The external threads of the externally threaded tube 262 and the externally threaded tube 264 are both adapted to the internal thread of the internally threaded tube 261. Both external threaded tube 262 and external threaded tube 264 can be threadedly connected to internal threaded tube 261. When external threaded tube 262 is threadedly connected to internal threaded tube 261, extension tube 263 is on the outside and is used to extend the length of telescopic push rod 26. When external threaded tube 264 is threadedly connected to internal threaded tube 261, extension tube 263 can be retracted into internal threaded tube 261. The outer diameter of extension tube 263 is smaller than the inner diameter of internal threaded tube 261. When external threaded tube 262 is threadedly separated from internal threaded tube 261, extension tube 263 can slide into internal threaded tube 261 and be retracted.

[0028] The depth adjustment component 5 includes a locking block 51, a concave locking groove at the rear of the locking block 51, a damping rotating shaft 52 fixedly connected to the top of the locking block 51, a stop bar 54 fixedly connected to the outer surface of the damping rotating shaft 52, a movable groove at one side of the top of the locking block 51, a limiting square plate 53 fixedly connected in the movable groove, and a through hole at the front of the locking block 51, into which a pin 55 is inserted and installed. The locking block 51 is fixed to the handcart 1 by the pin 55. The stop bar 54 is rotated above the slide rail 6 by the damping shaft 52 to block the slider platform 7 sliding on the outer surface of the slide rail 6. The slider platform 7 can be restricted from sliding according to the drilling depth requirements. The limiting square plate 53 is used to limit the position of the stop bar 54.

[0029] The pin 55 passes through the through hole, passes through the locking block 51, and extends into the insertion hole of the handcart 1. One side of the limiting square plate 53 abuts against one side of the stop bar 54. The pin 55 passes through the locking block 51 and extends into the insertion hole of the handcart 1 to fix the position of the depth adjustment component 5, and the limiting square plate 53 blocks the stop bar 54.

[0030] The limiting square plate 53 includes a spring 532. One end of the spring 532 is fixedly connected to the bottom of the movable groove of the limiting square plate 53, and the other end of the spring 532 is fixedly connected to the plate body 531. The elastic force of spring 532 pushes the limiting square plate 53 to block the stop bar 54. When it is necessary to adjust the angle of the stop bar 54, simply press the limiting square plate 53 to compress the spring 532, so that the height of the limiting square plate 53 is lower than the stop bar 54, and then the stop bar 54 can be rotated. The operation is convenient.

[0031] In use, the operator starts the gasoline engine 3, and the auger drill rod 4 begins to rotate. The operator, positioned behind the handcart 1, grips the handle 265 of the telescopic push rod 26 to apply force to the slider platform 7, pushing the slider platform 7, the top-mounted gasoline engine 3, and the auger drill rod 4 together to slide smoothly forward along the slide rail 6, thus drilling holes in the waste rock pile. The uniform, straight-line forward movement facilitates the formation of the installation hole. Before use, according to the operator's habits and work position, the external threaded tube 262 is screwed into the internal threaded tube 261 via a threaded connection, allowing the extension tube 263 to extend to a suitable length. To achieve a comfortable operating distance, during drilling operations, the hollow cylinder 21 and baffle 23 located between the auger rod 4 and the operator provide protection for the operator and block drilling debris, ensuring the operator's safety. After drilling is completed, the segmented heat pipes inserted into the rubber filler block 22 are removed for heat pipe assembly and installation. During drilling, the equipment is also equipped with a depth adjustment component 5 to precisely control the drilling depth. Several insertion holes are provided on the front and rear side beams of the handcart 1, allowing for adjustments based on the required depth. Select the corresponding insertion hole on the handcart 1. This can be measured using a ruler or similar measuring tool. Secure the concave groove of the locking block 51 onto the handcart 1. Then, pass the pin 55 through the through hole into the insertion hole of the handcart 1 for fixation. At this point, the stop rod 54 is positioned horizontally above the slide rail 6, abutting against the plate 531. The plate 531 is located in the forward direction of the slider platform 7, thus being blocked by the stop rod 54. A spring 532 is connected to the bottom of the plate 531, providing elasticity to the plate 531, thereby locking the stop rod 54 and achieving mechanical self-locking. When the slider platform 7 is in direct contact with the stop bar 54, the movement of the slider platform 7 is blocked, and the drilling stops. At this time, the drilling reaches the preset depth. Press the plate 531 of the limiting square plate 53 to compress the spring 532, so that the height of the plate 531 is lower than the stop bar 54. Then the stop bar 54 can be rotated through the damping shaft 52 to release the limit. If the depth adjustment component 5 is not needed, the pin 55 can be pulled out from the insertion hole of the handcart 1 to remove the depth adjustment component 5. In addition, when it is necessary to transport or store the equipment, the telescopic push rod 26 can be fully screwed into the retracted state to reduce the space occupied.
