Description

Technical Field

[0001] This invention relates to the technical field of pneumatic down-the-hole hammer testing equipment, and specifically to a large-diameter pneumatic down-the-hole hammer pushing device. Background Technology

[0002] In down-the-hole (DH) hammer testing, the installation of the DH hammer is a crucial step, significantly impacting the successful conduct of the test. With the continuous development of related technologies, the demand for and application of large-diameter pneumatic DH hammers is increasing. Efficient and stable DH hammer transportation and installation technologies can improve the utilization efficiency of DH hammers and provide strong support for related engineering construction. Previously, the pushing or transportation of large-diameter pneumatic DH hammers was often done using workshop cranes. Cranes have a certain lifting capacity, capable of lifting the DH hammer and moving it to the appropriate location. However, large-diameter pneumatic DH hammers are quite heavy, and existing testing platforms are enclosed structures, preventing workshop cranes from pushing them into the platform, thus hindering the conduct of DH hammer testing experiments. Summary of the Invention

[0003] In view of this, the present invention provides a large-diameter pneumatic down-the-hole hammer pushing device to solve the problem that large-diameter pneumatic down-the-hole hammers are heavy, and existing testing platforms are enclosed structures, making it impossible for workshop cranes to push them into the platform, thus preventing the conduct of down-the-hole hammer testing experiments.

[0004] In a first aspect, this application discloses a large-diameter pneumatic down-the-hole hammer pushing device, comprising: a support unit, which includes a base and a track, the base being disposed on the ground, the track being laid on the base unit, and the track extending along a transport path; a vehicle body, which has a receiving groove, and the vehicle body is rotatably connected to the track; a down-the-hole hammer body, the hammer head of which is inserted into the receiving groove; and a traction assembly, connected to the vehicle body, for driving the vehicle body to move along the extension direction of the track.

[0005] Beneficial Effects: The base provides an installation foundation for the track, ensuring a firm track installation and extending along the transport path, providing reliable guidance for vehicle movement. The rolling connection between the vehicle and the track reduces friction during vehicle movement, facilitating smooth movement. The receiving slot on the vehicle positions the down-the-hole hammer, allowing the hammer head to be securely placed within the slot via an insertion method, preventing displacement or shaking during transport. The traction component connects to the vehicle, driving it to move along the track's extension direction, thereby moving the down-the-hole hammer along a preset path. This allows for the smooth pushing of large-diameter pneumatic down-the-hole hammers into the enclosed testing platform, solving the problem of existing platforms being unable to conduct tests due to their enclosed structure and the inability of workshop cranes to push them, ensuring the smooth conduct of down-the-hole hammer testing. Furthermore, the overall structure is simple, adaptable to the weight requirements of large-diameter pneumatic down-the-hole hammers, provides stable load-bearing capacity, and is easy to operate.

[0006] In one alternative embodiment, the vehicle body has a through hole that communicates with the receiving groove and is connected to the bottom wall of the receiving groove.

[0007] Beneficial effects: The through-hole on the vehicle body, communicating with and connecting to the bottom wall of the receiving slot, reduces the vehicle's weight and the driving load on the traction components, making movement more effortless and efficient. Furthermore, the through-hole assists in the installation and positioning of the down-the-hole hammer, facilitates observation of the hammer head's fit with the receiving slot, and provides space for pipeline layout and testing operations during testing, enhancing the device's practicality and operational flexibility. In addition, the connection between the through-hole and the receiving slot prevents water and dust accumulation inside the slot, facilitating cleaning and maintenance.

[0008] In an optional embodiment, the system further includes a movable assembly comprising: an inner flange abutting against the inner wall of the receiving groove; an outer flange abutting against the outer wall of the vehicle body, the outer flange being fixedly connected to the inner flange by bolts; a roller having an annular groove thereon, into which a portion of the track segment is inserted; a shaft having one end fixedly connected to the roller and the other end rotatably connected to the inner wall of the outer flange; and a bearing located between the shaft and the inner wall of the outer flange, and sleeved on the outer periphery of the shaft.

[0009] Beneficial effects: The inner flange abuts against the inner wall of the receiving tank, and the outer flange abuts against the outer wall of the vehicle body. The outer flange is fixedly connected to the inner flange with bolts, ensuring a reliable connection. This connection can withstand the load from the weight of the large-diameter pneumatic down-the-hole hammer, preventing the moving components from falling off or loosening during use. The annular groove on the roller can be inserted into the track section to limit the roller's movement, preventing it from deviating from its intended path and ensuring the vehicle body moves along the track. The shaft rotatably connects the roller to the inner wall of the outer flange. A bearing, fitted around the outer circumference of the shaft and located between the shaft and the inner wall of the outer flange, reduces rotational friction between the shaft and the outer flange, making the roller rotate more smoothly. This further reduces resistance during vehicle movement, improving the stability and flexibility of the vehicle's movement, while also reducing component wear and extending the device's service life.

[0010] In one alternative embodiment, two tracks are provided, at least two moving components are provided, the two moving components are provided on both sides of the vehicle body, and two track segments are respectively inserted into the two annular grooves.

[0011] Beneficial effects: By setting up two tracks and cooperating with at least two moving components on both sides of the vehicle body, the annular groove of each moving component is inserted into the corresponding track segment, so that both sides of the vehicle body can obtain stable support and guidance, and the force is balanced. This avoids the vehicle body from tilting or deforming due to excessive force on one side caused by the large weight of the large-diameter pneumatic down-the-hole hammer, and improves the stability of the vehicle body under load and the smoothness during movement.

[0012] In one optional embodiment, the traction assembly includes: a first motor, fixedly connected to the factory floor; a reducer, drivingly connected to the output shaft of the first motor; a reel, sleeved on the outer periphery of the output shaft of the reducer and fixedly connected to the output shaft of the reducer; and a wire rope, wound on the reel, with one end of the wire rope connected to the vehicle body.

[0013] Beneficial Effects: The first motor is fixedly connected to the factory floor, ensuring a stable installation and providing consistent power output for traction. The reducer is connected to the output shaft of the first motor, allowing adjustment of the motor's output speed and torque. This ensures the power output is better suited to the weight requirements of the vehicle and the down-the-hole hammer, preventing unstable pushing or failure to push due to excessive speed or insufficient torque. The reel is sleeved and fixed on the reducer's output shaft, rotating synchronously with it to wind and unwind the wire rope. The wire rope drives the vehicle's movement, resulting in high transmission efficiency and stable power transmission. This traction structure eliminates the need for manual pushing, achieving a high degree of automation and saving labor costs. It also allows control of the vehicle's speed and distance, ensuring the down-the-hole hammer is pushed to the designated position on the test platform, improving the efficiency and accuracy of test preparation.

[0014] In one alternative embodiment, the traction assembly further includes a wire rope clip mounted on the vehicle body for detachable connection with the wire rope.

[0015] Beneficial effects: Adding a wire rope clip mounted on the vehicle body to the traction assembly allows for detachable connection of the wire rope, making connection and disconnection of the wire rope to the vehicle body more convenient. Once the down-the-hole hammer is pushed to the designated position, the connection between the wire rope and the vehicle body can be quickly detached without affecting the hammer's testing operation. When it is necessary to move the down-the-hole hammer or perform maintenance on the device, the wire rope can also be easily separated from the vehicle body, improving the device's operational flexibility and maintenance convenience. Simultaneously, the reliable connection method of the wire rope clip ensures a secure connection between the wire rope and the vehicle body during traction, preventing the wire rope from detaching and causing interruptions in pushing or safety accidents, thus guaranteeing the safety and stability of the traction operation.

[0016] In one optional embodiment, the traction assembly further includes: a friction disc, coaxially arranged with the reel; a brake drive, fixedly connected to the factory floor; and a first brake block and a second brake block arranged opposite to each other, both of which are connected to the brake drive; the brake drive is capable of driving the first brake block and the second brake block to move closer or further apart from each other to grip or release the friction disc.

[0017] Beneficial effects: The newly added friction disc in the traction assembly is coaxially arranged with the reel. The brake drive unit moves the first and second brake blocks, which are positioned opposite each other, closer or further apart, thus tightening or loosening the friction disc. When the vehicle needs to stop moving or remain in a specific position, the brake drive unit drives the two brake blocks to tighten the friction disc, limiting the rotation of the reel through friction, thereby fixing the wire rope and preventing the vehicle from slipping due to inertia or the weight of the down-the-hole hammer. This ensures the accuracy of the down-the-hole hammer's position during pushing and its parking safety. When it is necessary to continue moving the vehicle, the brake blocks release the friction disc without affecting the normal rotation of the reel. The operation is flexible and the braking is reliable, further improving the safety performance and operational stability of the entire device.

[0018] In one alternative embodiment, at least two carrier units are provided, and the two carrier units are spliced ​​end to end.

[0019] Beneficial effects: The system uses at least two carrier units, spliced ​​end-to-end. The number of carrier units can be flexibly adjusted according to the location of the testing platform and the required pushing distance of the down-the-hole hammer, thereby extending the total length of the track and adapting to different pushing scenarios, improving the versatility and adaptability of the device. The spliced ​​structure facilitates the transportation, installation, and disassembly of the carrier units. When the testing site changes or the device needs to be moved, the carrier units can be disassembled for transport, reducing operational difficulty. Simultaneously, the overall support after multiple carrier units are spliced ​​is stable, providing continuous and reliable support for the track and vehicle body, ensuring that the down-the-hole hammer maintains stable movement during long-distance pushing and avoiding the impact of insufficient track length or unstable support on the pushing effect.

[0028] This application mainly uses a base 101, a track 102, a car body 201, a down-the-hole hammer, and a traction assembly to achieve the effect of smoothly pushing a large-diameter pneumatic down-the-hole hammer into the closed testing platform, ensuring the smooth conduct of the test. The following is a further detailed description of this application.

[0029] The large-diameter pneumatic down-the-hole hammer pushing device provided in the embodiments of this application, such as Figures 1 to 5As shown, the system includes a support unit, a vehicle body 201, a down-the-hole hammer body 301, and a traction assembly. The support unit's base 101 is placed on the ground, and a track 102 is laid on the base 101 and extends along the transport path. The vehicle body 201 is rotatably connected to the track 102. The hammer head of the down-the-hole hammer body 301 is inserted into the receiving groove 2011 on the vehicle body 201. The traction assembly is connected to the vehicle body 201 and drives the vehicle body 201 to move along the extension direction of the track 102. This achieves the effect of smoothly pushing a large-diameter pneumatic down-the-hole hammer into the enclosed testing platform, solving the problem that existing platforms cannot conduct testing experiments due to their enclosed structure. The base 101 provides a stable installation foundation for the track 102, ensuring that the track 102 is laid firmly and can guide the movement of the vehicle body 201; the rolling connection between the vehicle body 201 and the track 102 reduces friction and makes the vehicle body 201 move smoothly; the receiving groove 2011 positions the down-the-hole hammer body 301 to prevent it from shifting or shaking during transportation; the traction component drives the vehicle body 201 to move the down-the-hole hammer body 301.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the supporting unit includes a base 101 and a track 102. The base 101 is made of metal; in this embodiment, it is made of alloy steel. Alloy steel ensures that the base 101 has sufficient strength and stability to support the weight of the track 102, the vehicle body 201, and the down-the-hole hammer. The base 101 can be block-shaped or plate-shaped, and those skilled in the art can select according to the actual site and usage requirements. In an alternative embodiment, the base 101 can also be made of cast concrete to enhance its bonding force and stability with the ground. The base 101 is fixed to the ground by bolts or welding to ensure its fixed position. The track 102 is generally made of steel rails, which have high hardness and wear resistance, and can withstand the pressure of the vehicle body 201 and the down-the-hole hammer. The track 102 is laid on the base 101 and extends along the transport path; its extension direction is planned according to the transport requirements of the down-the-hole hammer. The track 102 can be installed by fixing it to the seat 101 with bolts, or by using a slotted connection to ensure a tight fit between the track 102 and the seat 101. The combination of the seat 101 and the track 102 provides a solid foundation and reliable guidance for the movement of the vehicle body 201, enabling the vehicle body 201 to move smoothly along a preset path.

[0031] Specifically, such as Figure 1 and Figure 2As shown, a receiving groove 2011 is provided on the vehicle body 201, and the vehicle body 201 is rotatably connected to the track 102. The vehicle body 201 can be a rectangular structure, which is simple and has good stability. The material of the vehicle body 201 can be high-strength alloy steel to ensure that it can withstand the weight of the down-the-hole hammer. The receiving groove 2011 is provided on the vehicle body 201, and its shape and size are adapted to the hammer head of the down-the-hole hammer body 301, so that the hammer head can be tightly inserted into the receiving groove 2011. The inner wall of the receiving groove 2011 can be lined with cushioning materials such as rubber pads to reduce the collision and wear between the down-the-hole hammer and the vehicle body 201 during transportation. The rotatable connection between the vehicle body 201 and the track 102 can be achieved by rollers 503 installed at the bottom of the vehicle body 201. The rollers 503 can be made of high-strength bearing steel 505, which has good wear resistance and rotation performance. The roller 503 contacts the track 102 via rolling friction, which greatly reduces the friction when the vehicle body 201 moves, making the movement of the vehicle body 201 smoother. The receiving groove 2011 on the vehicle body 201 plays a role in positioning and fixing the down-the-hole hammer body 301, while the rolling connection between the vehicle body 201 and the track 102 ensures that the vehicle body 201 can move flexibly along the track 102.

[0032] Specifically, such as Figure 1 As shown, the hammer head of the down-the-hole hammer body 301 is inserted into the receiving groove 2011. The down-the-hole hammer body 301 is the object to be transported, and its hammer head is designed to match the shape of the receiving groove 2011. In this embodiment, the hammer head of the down-the-hole hammer body 301 is cylindrical. The surface of the hammer head can be smoothed to reduce friction with the inner wall of the receiving groove 2011. When the hammer head is inserted into the receiving groove 2011, a tight fit can be achieved, preventing the down-the-hole hammer from shaking or shifting during transportation.

[0033] Specifically, such as Figure 1 and Figure 5As shown, the traction assembly is connected to the vehicle body 201 and is used to drive the vehicle body 201 to move along the extension direction of the track 102. The first motor 401 of the traction assembly is fixedly connected to the factory floor by bolts to ensure that the first motor 401 is securely installed. The first motor 401 can be an AC motor or a DC motor, which can be selected by those skilled in the art according to the actual power requirements. The reducer 402 is drivenly connected to the output shaft of the first motor 401. The function of the reducer 402 is to adjust the output speed and torque of the first motor 401 so that the power output is more suitable for the weight requirements of the vehicle body 201 and the down-the-hole hammer. The reducer 402 can be a gear reducer 402 or a planetary reducer 402. The reel 403 is sleeved on the outer circumference of the output shaft of the reducer 402 and is fixedly connected to the output shaft of the reducer 402. When the output shaft of the reducer 402 rotates, the reel 403 rotates synchronously. The reel 403 is usually made of metal and the surface can be treated with anti-slip treatment to ensure that the wire rope 404 can be firmly wound on it. The wire rope 404 is wound around the reel 403, and one end is connected to the vehicle body 201. When the reel 403 rotates, the wire rope 404 winds and unwinds, thereby driving the vehicle body 201 to move along the extension direction of the track 102. The traction assembly is powered by the first motor 401. After being adjusted by the reducer 402, the reel 403 and the wire rope 404 traction the vehicle body 201, enabling the vehicle body 201 to drive the down-the-hole hammer body 301 to move.

[0034] In this embodiment, the large-diameter pneumatic down-the-hole hammer pushing device provides support and guidance for the vehicle body 201 through the base 101 of the support unit and the track 102. The receiving groove 2011 on the vehicle body 201 positions and fixes the down-the-hole hammer body 301. The traction component drives the vehicle body 201 to move along the track 102, thereby smoothly pushing the large-diameter pneumatic down-the-hole hammer into the enclosed inspection and testing platform. This solves the problem that the workshop crane cannot push the down-the-hole hammer due to the enclosed platform structure, ensuring the smooth conduct of down-the-hole hammer testing. At the same time, the overall structure is simple, adaptable to the weight requirements of the large-diameter pneumatic down-the-hole hammer, has stable load-bearing capacity, is easy to operate, and improves the transportation efficiency of the down-the-hole hammer.

[0035] In this embodiment, as Figure 3As shown, a through hole 2012 is provided on the vehicle body 201, which communicates with the receiving groove 2011 and is connected to the bottom wall of the receiving groove 2011. The through hole 2012 can be circular, square, or other common shapes. The function of the through hole 2012 is twofold: firstly, to reduce the weight of the vehicle body 201 itself, thereby reducing the driving load on the traction component and making the movement of the vehicle body 201 more effortless and efficient. When the weight of the vehicle body 201 is reduced, the driving force required by the first motor 401 will be reduced accordingly, thus reducing energy consumption. Secondly, the through hole 2012 can assist in the installation and positioning of the down-the-hole hammer body 301. The operator can observe the insertion and fit between the hammer head and the receiving groove 2011 through the through hole 2012 to ensure accurate installation. At the same time, during the testing process, the through hole 2012 can also reserve space for the layout of related pipelines and testing operations, improving the practicality and operational flexibility of the device. Furthermore, the connection between the through hole 2012 and the receiving groove 2011 prevents water and dust accumulation inside the receiving groove 2011, facilitating cleaning and maintenance of the interior of the receiving groove 2011. The through hole 2012 on the vehicle body 201 optimizes its structure, reducing its weight and driving load, while also providing convenience for the installation, inspection, and maintenance of the down-the-hole hammer, further enhancing the performance and practicality of the large-diameter pneumatic down-the-hole hammer pushing device.

[0036] In this embodiment, as Figure 1 and Figure 3As shown, the system also includes a moving assembly, which comprises an inner flange 501, an outer flange 502, a roller 503, a shaft 504, and a bearing 505. The inner flange 501 abuts against the inner wall of the receiving groove 2011, and its shape and size are adapted to the inner wall of the receiving groove 2011. The inner flange 501 is made of metal; in this embodiment, it is made of aluminum alloy, which has certain strength and corrosion resistance. The surface of the inner flange 501 can be smoothed to reduce friction with the inner wall of the receiving groove 2011. The outer flange 502 abuts against the outer wall of the vehicle body 201 and is also made of metal. The outer flange 502 is fixedly connected to the inner flange 501 by bolts. This connection method is reliable and can withstand the load from the weight of the large-diameter pneumatic down-the-hole hammer, preventing the moving assembly from falling off or loosening during use. The roller 503 has an annular groove into which a section of the track 102 is inserted. The roller 503 is made of high-strength alloy steel, possessing good wear resistance and strength. The size and shape of the annular groove match the track 102 section, enabling the track 102 to limit the movement of the roller 503 and prevent the roller 503 from deviating while rolling on the track 102. One end of the shaft 504 is fixedly connected to the roller 503, and the other end is rotatably connected to the inner wall of the outer flange 502. The shaft 504 can be a solid shaft or a hollow shaft, selected according to the actual load-bearing requirements. The surface of the shaft 504 can be heat-treated to improve its hardness and wear resistance. The bearing 505 is located between the shaft 504 and the inner wall of the outer flange 502, and is sleeved on the outer circumference of the shaft 504. The bearing 505 can be a rolling bearing 505, which has low friction and high rotational efficiency. The combination of inner flange 501, outer flange 502, roller 503, shaft 504, and bearing 505 enables the moving assembly to be stably mounted on the vehicle body 201 and achieves a rolling connection between the vehicle body 201 and the track 102, further improving the smoothness and flexibility of the vehicle body 201's movement. The connection between the inner flange 501 and the outer flange 502 securely mounts the moving assembly on the vehicle body 201; the annular groove of the roller 503 engages with the track 102 to guide and limit the movement of the vehicle body 201; and the engagement of the shaft 504 and bearing 505 reduces rotational friction, making the movement of the vehicle body 201 smoother. Compared to existing technologies, the addition of the moving assembly improves the stability and reliability of the large-diameter pneumatic down-the-hole hammer pushing device.

[0037] In this embodiment, as Figure 3As shown, two tracks 102 are provided, and at least two moving components are provided. The two moving components are located on both sides of the vehicle body 201, with two track 102 segments inserted into each of the two annular grooves. The two tracks 102 are laid parallel to the base 101, providing more stable support and guidance for the vehicle body 201. The spacing of the tracks 102 is determined according to the width of the vehicle body 201 and design requirements, ensuring that the vehicle body 201 can move smoothly on the tracks 102. The moving components are located on both sides of the vehicle body 201, with each moving component's annular groove inserting into a corresponding track 102 segment, ensuring stable support and guidance on both sides of the vehicle body 201. This arrangement ensures balanced force on the vehicle body 201, preventing tilting and deformation caused by excessive force on one side due to the large weight of the large-diameter pneumatic down-the-hole hammer, thus improving the stability of the vehicle body 201 under load and its smoothness during movement. The arrangement of two tracks 102 and at least two moving components optimizes the stress structure of the vehicle body 201, making it more stable and smoother when transporting large-diameter pneumatic down-the-hole hammers. Compared to a single track 102 and a single moving component, this structure can better accommodate the weight and size of large-diameter pneumatic down-the-hole hammers, improving the load-bearing capacity and transport performance of the device.

[0038] In this embodiment, the traction assembly also includes a wire rope 404 clip 405, a friction disc, a brake drive component, a first brake block, and a second brake block. At least two load-bearing units are provided, with the two load-bearing units spliced ​​end-to-end. The wire rope 404 clip 405 is mounted on the vehicle body 201 for detachable connection with the wire rope 404. The wire rope 404 clip 405 can adopt a quick-connect structure, such as a locking type or a bolt-fastening type, facilitating quick connection and disconnection of the wire rope 404 by operators. When the down-the-hole hammer is pushed to the designated position, the connection between the wire rope 404 and the vehicle body 201 can be quickly disassembled without affecting the testing operation of the down-the-hole hammer. When it is necessary to move the down-the-hole hammer or perform maintenance on the device, the wire rope 404 can also be easily separated from the vehicle body 201, improving the operational flexibility and maintenance convenience of the device. Meanwhile, the connection method of the wire rope 404 and the buckle 405 is reliable, ensuring that the wire rope 404 is firmly connected to the vehicle body 201 during traction, preventing the wire rope 404 from falling off and causing interruption of pushing or safety accidents. The friction disc and the reel 403 are coaxially arranged, and the brake drive component is fixedly connected to the factory floor. The first and second brake blocks, which are arranged opposite each other, are both connected to the brake drive component. The brake drive component can be hydraulically driven or electrically driven, and can drive the first and second brake blocks to move closer or further apart to tighten or loosen the friction disc. When the vehicle body 201 needs to stop moving or be held in a specific position, the brake drive component drives the two brake blocks to tighten the friction disc, limiting the rotation of the reel 403 through friction, thereby fixing the wire rope 404 and preventing the vehicle body 201 from slipping due to inertia or the weight of the down-the-hole hammer, ensuring the positional accuracy and parking safety of the down-the-hole hammer during pushing. When it is necessary to continue moving the vehicle body 201, the brake blocks release the friction disc without affecting the normal rotation of the reel 403. The device comprises at least two carrier units, which are spliced ​​end-to-end. The carrier units can be spliced ​​using bolts or slots to ensure a tight connection. This allows for flexible adjustment of the number of carrier units based on the location of the testing platform and the required pushing distance of the down-the-hole hammer, thereby extending the total length of track 102 and adapting to different pushing scenarios, enhancing the device's versatility and adaptability. The spliced ​​structure facilitates the transportation, installation, and disassembly of the carrier units. When the testing site changes or the device needs to be moved, the carrier units can be disassembled for transport, reducing operational difficulty. Simultaneously, the overall support provided by multiple spliced ​​carrier units is stable, offering continuous and reliable support to track 102 and vehicle body 201, ensuring the down-the-hole hammer maintains stable movement during long-distance pushing. The addition of wire rope 404 clips 405, friction discs, brake drive components, first brake block, and second brake block improves the functionality of the traction assembly, enhancing the safety and controllability of the traction process. The wire rope 404 clip 405 facilitates the connection and disassembly of the wire rope 404 and the vehicle body 201; the cooperation of the friction disc and the brake block enables the braking and positioning of the vehicle body 201.The splicing design of the load-bearing unit allows the device to flexibly adjust the length of the track 102 according to actual needs, improving the device's versatility and adaptability. Compared with existing technologies, it can better meet the transportation needs of large-diameter pneumatic down-the-hole hammers in different scenarios.
