Description

Technical Field

[0001] This application relates to the field of hole reaming device technology, and more particularly to a hole reaming device for a rotary drilling rig. Background Technology

[0002] The published patent document CN 220769365 U discloses a hole-reaming device for a rotary drilling rig, including a reaming shank and a drill head. The top of the drill head is located at one end of the reaming shank. Two auxiliary grooves are formed on the surface of the reaming shank, and each auxiliary groove contains a moving block. A disc is located on one side of each moving block, and a limit bar is located on one side of the top of the disc. A storage cylinder is located at one end of the limit bar, and the storage cylinder is filled with cutting fluid. By setting up the moving blocks, discs, storage cylinder, collecting rod, and absorbent cotton strips, the two moving blocks move up and down inside the corresponding two auxiliary grooves, which drives the disc to move and inject the cutting fluid into the storage cylinder. The absorbent cotton strips are made of sponge and have water-absorbing properties. After absorbing the cutting fluid, the surface of the drill head becomes gradually wet. Thus, by applying multiple absorbent cotton strips to the surface of the drill head, the lubrication ability of the drill head is increased, the resistance to drilling is reduced, and the drilling process is made easier.

[0003] In actual use, the absorbent tampons are consumables and need to be replaced regularly, which increases maintenance costs and the workload of workers. Therefore, this application provides another solution to this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a hole enlarging device for a rotary drilling rig, which overcomes the shortcomings of the prior art and aims to solve the problem that the above devices are consumables that need to be replaced regularly, which increases maintenance costs and the workload of workers.

[0005] To achieve the above objectives, this application provides the following technical solution: a borehole reaming device for a rotary drilling rig, comprising a drill head, a lower connecting plate fixedly mounted on the top of the drill head, an oil spraying mechanism provided on the top of the lower connecting plate, an upper connecting plate provided on the top of the oil spraying mechanism, a borehole reaming handle fixedly mounted on the top of the upper connecting plate, the oil spraying mechanism comprising a height adjuster, a fixed plate fixedly mounted on the top of the height adjuster, a motor fixedly mounted on the top of the fixed plate, a crossbar fixedly mounted on the output end of the motor, an adjusting rod fixedly mounted on the top of the crossbar, a rotating seat fixedly mounted on the bottom of the upper connecting plate, the top of the adjusting rod rotatably connected to the interior of the rotating seat, an extension rod fixedly mounted on one side of the crossbar, a liquid reservoir fixedly mounted on the top of the crossbar located on one side of the adjusting rod, a suction pipe fixedly mounted on one side of the liquid reservoir, a connecting pipe fixedly mounted inside the extension rod, the connecting pipe communicating with the suction pipe, and a nozzle mounted on the bottom of the extension rod, the nozzle communicating with the connecting pipe.

[0006] By adopting the above technical solution, the cutting fluid in the reservoir is extracted using a suction pipe and transported to the nozzle through a connecting pipe. The cutting fluid is atomized and sprayed out through the nozzle. The rotation of the crossbar and extension rod driven by the motor causes the nozzle to rotate around the lower connecting plate. This facilitates the uniform coverage of the drill bit surface with the cutting fluid, increases the lubrication capacity of the lower connecting plate, and reduces the resistance encountered during drilling. Therefore, drilling is made simpler. At the same time, this solution reduces the need for manual intervention and improves the level of intelligence in the operation.

[0007] As a preferred technical solution of this application, a guide rail is fixedly installed inside the fixed plate, a guide block is fixedly connected to the sliding end of the guide rail, and the top end of the guide block is fixedly installed at the bottom end of the crossbar.

[0008] By adopting the above technical solution, the guide block rotates on the guide rail as the crossbar rotates, which helps to provide support and guidance for the crossbar.

[0009] As a preferred technical solution of this application, a solenoid valve is fixedly installed inside the nozzle.

[0010] By adopting the above technical solution, the solenoid valve facilitates precise control of the cutting fluid flow rate, improving its practicality during use.

[0011] As a preferred technical solution of this application, the nozzle is hinged to the extension rod.

[0012] By adopting the above technical solution, the nozzle and extension rod are hinged together, allowing the spray direction of the nozzle to be adjusted, thus improving the flexibility of use.

[0013] As a preferred technical solution of this application, the top of the liquid reservoir is threadedly connected to a liquid filling pipe, and a filter plate is installed inside the liquid filling pipe.

[0014] By adopting the above technical solution, the liquid reservoir can be easily replenished through the liquid filling pipe, and impurities can be filtered through the filter plate to ensure the cleanliness of the added lubricant. This prevents impurities from clogging the nozzle when they are delivered to it, thus improving the protection effect on the nozzle.

[0015] As a preferred technical solution of this application, the height adjuster is an electric push rod, and the adjusting rod is a telescopic rod.

[0016] By adopting the above technical solution, the height of the extension rod is adjusted by the electric telescopic extension of the height adjuster. When the crossbar rises, it compresses the adjusting rod, making it easy to adjust the position of the extension rod when it is not in use.

[0017] As a preferred technical solution of this application, the top of the liquid filling tube is threaded with a cap.

[0018] By adopting the above technical solution, the liquid filling tube is connected to the cap by a thread, which facilitates the disassembly and cleaning of the liquid filling tube.

[0019] As a preferred technical solution of this application, a liquid level observation window is fixedly installed on the outer surface of the liquid reservoir.

[0020] By adopting the above technical solution, the liquid level in the reservoir can be observed through the liquid level observation window, which makes it easy for operators to intuitively understand the remaining amount of cutting fluid and facilitates timely replenishment.

[0021] The beneficial effects of this application are:

[0022] 1. The cutting fluid in the reservoir is extracted using a suction pipe and transported to the nozzle through a connecting pipe. The cutting fluid is atomized and sprayed out through the nozzle. The rotation of the crossbar and extension rod driven by the motor causes the nozzle to rotate around the lower connecting plate. This facilitates the even coverage of the cutting fluid on the surface of the drill bit, increases the lubrication capacity of the lower connecting plate, and reduces the resistance encountered during drilling. Therefore, drilling is made easier. At the same time, this solution reduces the need for manual intervention and improves the level of intelligence in the operation.

[0023] 2. As the crossbar rotates, it drives the guide block to rotate on the guide rail, which helps to provide support and guidance for the crossbar. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A hole-reaming device for a rotary drilling rig includes a drill head 1, a lower connecting plate 2 fixedly mounted on the top of the drill head 1, an oil spraying mechanism 3 disposed on the top of the lower connecting plate 2, an upper connecting plate 4 disposed on the top of the oil spraying mechanism 3, a hole-reaming handle 5 fixedly mounted on the top of the upper connecting plate 4, the oil spraying mechanism 3 including a height adjuster 301, a fixing plate 302 fixedly mounted on the top of the height adjuster 301, a motor 303 fixedly mounted on the top of the fixing plate 302, a crossbar 304 fixedly mounted on the output end of the motor 303, an adjusting rod 306 fixedly mounted on the top of the crossbar 304, and a bottom end of the upper connecting plate 4. A rotating base 305 is fixedly installed. The top of the adjusting rod 306 is rotatably connected to the inside of the rotating base 305. An extension rod 307 is fixedly installed on one side of the crossbar 304. A liquid reservoir 308 is fixedly installed on the top of the crossbar 304, located on one side of the adjusting rod 306. A liquid extraction pipe 309 is fixedly installed on one side of the liquid reservoir 308. A connecting pipe 310 is fixedly installed inside the extension rod 307 and is connected to the liquid extraction pipe 309. A nozzle 311 is installed at the bottom of the extension rod 307 and is connected to the connecting pipe 310. A solenoid valve 312 is fixedly installed inside the nozzle 311.

[0031] The cutting fluid in the reservoir 308 is extracted using the extraction pipe 309 and transported to the nozzle 311 via the connecting pipe 310. The cutting fluid is atomized and sprayed out through the nozzle 311. The rotation of the crossbar 304 and extension rod 307 driven by the motor causes the nozzle 311 to rotate around the lower connecting plate 2. This facilitates the uniform coverage of the drill bit surface with cutting fluid, increases the lubrication capacity of the lower connecting plate 2, and reduces the resistance encountered during drilling, thus making drilling easier. At the same time, this solution reduces the need for manual intervention and improves the level of intelligence in the operation. The solenoid valve 312 allows for precise control of the cutting fluid flow rate, improving its practicality during use.

[0032] Reference Figure 1-3 The guide rail 6 is fixedly installed inside the fixed plate 302. The sliding end of the guide rail 6 is fixedly connected to the guide block 7. The top end of the guide block 7 is fixedly installed at the bottom end of the crossbar 304. The nozzle 311 is hinged to the extension rod 307. The height adjuster 301 is an electric push rod, and the adjusting rod 306 is a telescopic rod.

[0033] As the crossbar 304 rotates, it drives the guide block 7 to rotate on the guide rail 6, which helps to provide support and guidance for the crossbar 304. The nozzle 311 is hinged to the extension rod 307, which allows the spray direction of the nozzle 311 to be adjusted, improving the flexibility of use. The height of the extension rod 307 is adjusted by the electric extension and retraction of the height adjuster 301. When the crossbar 304 rises, it compresses the adjusting rod 306, which facilitates the position adjustment of the extension rod 307 when it is not in use.

[0034] Reference Figure 4 The top of the reservoir 308 is threadedly connected to a filling pipe 9, and a filter plate 10 is installed inside the filling pipe 9. A cap 11 is threadedly connected to the top of the filling pipe 9. The filling pipe 9 facilitates the replenishment of the reservoir 308. The filter plate 10 filters impurities to ensure the cleanliness of the added lubricant and prevents impurities from being transported to the nozzle 311 and causing blockage, thus improving the protection of the nozzle 311. The threaded connection between the filling pipe 9 and the cap 11 facilitates the disassembly and cleaning of the filling pipe 9.

[0035] Reference Figure 2 A liquid level observation window 12 is fixedly installed on the outer surface of the liquid reservoir 308; the liquid level in the liquid reservoir 308 can be observed through the liquid level observation window 12, which makes it easy for operators to intuitively understand the remaining amount of cutting fluid and facilitates timely replenishment.

[0036] Working principle: The cutting fluid in the reservoir 308 is extracted using the extraction pipe 309 and transported to the nozzle 311 through the connecting pipe 310. The cutting fluid is atomized and sprayed out through the nozzle 311. The rotation of the crossbar 304 and the extension rod 307 driven by the motor causes the nozzle 311 to rotate around the lower connecting plate 2. This allows the cutting fluid to evenly cover the surface of the drill bit, increases the lubrication capacity of the lower connecting plate 2, and reduces the resistance to drilling, thus making drilling easier. At the same time, this solution reduces the need for manual intervention and improves the level of intelligence in the operation. During the rotation of the crossbar 304, the guide block 7 rotates on the guide rail 6, which helps to provide support and guidance for the crossbar 304.

[0037] Among them, the solenoid valve 312 is conducive to precise control of the flow rate of cutting fluid, which improves the practicality of use. The nozzle 311 is hinged to the extension rod 307, which allows the spray direction of the nozzle 311 to be adjusted, improving the flexibility of use.

[0038] Meanwhile, the liquid filling pipe 9 facilitates the replenishment of the liquid reservoir 308, and the filter plate 10 filters impurities to ensure the cleanliness of the added lubricant, preventing impurities from clogging the nozzle 311 when it is transported to the nozzle 311, thus improving the protection effect of the nozzle 311; the height of the extension rod 307 is adjusted by the electric extension and retraction of the height adjuster 301, and the rise of the crossbar 304 compresses the adjusting rod 306, which facilitates the position adjustment of the extension rod 307 when it is not in use;

[0039] In addition, the addition pipe 9 is threadedly connected to the cap 11, which facilitates the disassembly and cleaning of the addition pipe 9. The liquid level in the reservoir 308 can be observed through the liquid level observation window 12, which allows the operator to intuitively understand the remaining amount of cutting fluid and facilitates timely replenishment.
