Description

Technical Field

[0001] The utility model belongs to the technical field of drilling tool accessories, in particular to a cleaning device for a long spiral drilling machine. Background Art

[0002] Long spiral drill rigs are commonly used basic construction equipment for pile foundation operations. They are used in housing construction, public construction and other construction fields. They are characterized by low construction vibration, low noise and fast hole-making speed. When the long spiral drill rig drills a hole, the power head of the drill rig drives the spiral drill rod and drill bit, causing the spiral blades to rotate downward to cut the soil layer. The cut soil layer is automatically discharged out of the hole along the spiral blades as the drill bit rotates. In actual construction, when drilling into relatively moist silty clay and silty soil, the drill bit and part of the long spiral drill rod are prone to drilling stickiness, that is, clay or silt adheres to the drill rod and spiral blades and is not easy to be thrown off, thereby causing drilling blockage and affecting the long spiral drilling speed; when drilling into dry sandy soil and silty clay, the drill rig is prone to generate dust, which affects on-site environmental protection management.

[0003] like Figure 1 As shown, the current long spiral drilling rigs are generally not equipped with soil cleaning and dust reduction devices. The mud adhering to the spiral drill rod is cleaned manually, which has many problems such as labor-consuming, time-consuming and unsafe. Therefore, a cleaning device for a long spiral drilling rig is provided to solve the above technical problems. Utility Model Content

[0024] The embodiment of the utility model provides a cleaning device for a long spiral drilling machine, which is described below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 As shown, a cleaning device for a long spiral drill can be connected to a long spiral drill 1 and a drill rod 4, including an inner cylinder 2 connected to the long spiral drill 1, a cleaning assembly 3 arranged on the inner side wall of the inner cylinder 2, and the drill rod 4 penetrates the inner cylinder 2 and contacts the cleaning assembly 3. When the drill rod is working, the cleaning assembly 3 can clean the impurities retained on the surface of the drill rod 4. In this embodiment, the drill rod 4 penetrates the inner cylinder 2 and contacts the cleaning assembly 3 on the inner side wall of the inner cylinder 2. When the drill rod 4 is working, the drill rod 4 moves downward and drives the drill rod 4 to rotate through the drilling rig power head. As the drill rod 4 moves and rotates, the cleaning assembly 3 distributed on the outside can scrape off the impurities retained on its surface. When the drill rod 4 is not working, it moves upward, and the impurities that are not cleaned up on the drill rod 4 will still be cleaned by the cleaning assembly 3, achieving the effect of secondary cleaning. Using this device, it is no longer necessary to manually clean the soil attached to the drilling rig, saving labor while avoiding safety problems such as falling objects from high altitude, and it is safer and more reliable.

[0026] Preferably, the inner cylinder 2 is a hollow tubular structure so that the cleaned impurities can be discharged from the bottom thereof.

[0027] Preferably, a plurality of cleaning components 3 are arranged along the inner wall of the inner tube 2 , and each cleaning component 3 comprises a baffle base 31 arranged on the side wall of the inner tube 2 , and a baffle 32 contacting the drill pipe 4 through the baffle base 31 .

[0028] Preferably, the sides of the multiple groups of baffles 32 away from the baffle base 31 are spiral-shaped and avoid the spiral blades 41 on the surface of the drill rod 4.

[0029] Preferably, Figure 6 As shown, the baffle base 31 includes a threaded bolt 312 connected to the inner wall of the inner tube 2, a hexagonal nut 311, a connecting plate 313 and a pad 314. The connecting plate 313 is connected to the inner wall of the inner tube 2 through the pad 314. The hexagonal nut 311 connects the threaded bolt 312, the connecting plate 313 and the pad 314 together. The side of the connecting plate 313 away from the pad 314 is connected to the baffle 32. Figure 5As shown, in this embodiment, four sets of threaded bolts 312 are provided on the connecting plate 313 to realize the detachable connection between the baffle base 31 and the inner tube 2. The pad 314 is placed between the inner tube 2 and the connecting plate 313 to fill the gap and protect the connection from loosening, etc., so as to facilitate later maintenance and repair.

[0030] Preferably, the baffle 32 is a length-adjustable member. In this embodiment, a baffle 32 of a suitable length is selected according to the size of the drill rod 4, so that the baffle 32 is away from the side of the baffle base 31 and contacts the surface of the drill rod, while avoiding the spiral blades 41 on the surface of the drill rod 4. When the drill rod 4 is needed, the inner tube 2 is relatively fixed to the long spiral drill 1. As the drill rod 4 moves and rotates, the baffle 32 scrapes off the dirt and other impurities trapped on its surface, and no separate cleaning time is required, saving construction time. It should be noted that the length-adjustable member is common knowledge in the art, and the user can flexibly adjust the length of the baffle 32 according to actual applications, which will not be further elaborated here.

[0031] Preferably, the inner tube 2 is connected to the base 6 via a support rod 5 , and the base 6 is connected to the long spiral drilling rig 1 via a fixed bracket 7 .

[0032] Preferably, the fixing bracket 7 is provided with a through hole, and the drill rod 4 passes through the through hole. In this embodiment, from top to bottom, the drill rod 4 passes through the inner tube 2 and the through hole in sequence, and the construction operation is carried out. The drill rod 4 can be cleaned while falling, which is more efficient.

[0033] Preferably, an outer cylinder 8 is provided on the outer side of the inner cylinder 2 , and the two are rotatably connected via a rolling bearing 13 .

[0034] Preferably, sealing rings are provided on both sides of the rolling bearing 13 along the direction of the inner cylinder 2 to limit the mutual movement between the inner cylinder 2 and the outer cylinder 8 .

[0035] Preferably, the outer cylinder 8 is connected to a driving motor to provide power for its rotation. In this embodiment, the outer side of the inner cylinder 2 is wrapped with the outer cylinder 8, and the outer cylinder 8 is rotatably connected to the support rod 5. A turntable 14 fixed to the support rod 5 is provided at the bottom of the outer cylinder 8. The driving motor can drive the outer cylinder 8 to rotate around the support rod 5. The top of the support rod 5 is fixedly connected to the inner cylinder 2 to limit the rotation of the inner cylinder 2, providing a good working environment for the cleaning operation.

[0036] Preferably, the outer cylinder 8 is rotatably connected to the support rod 5. In this embodiment, a plurality of bases 6 are provided on the top of the fixed bracket 7, the top of the base 6 is connected to the support rod 5, the top of the support rod 5 is simultaneously connected to the inner cylinder 2 and the outer cylinder 8, so as to stably support the entire cleaning device, the inner cylinder 2 is fixedly connected to the support rod 5, and the outer cylinder 8 is rotatably connected to the support rod 5, so that the inner cylinder 2 and the outer cylinder 8 can rotate relative to each other but cannot move relative to each other, and the outer side of the outer cylinder 8 is connected to the output end of the driving motor.

[0037] Preferably, a pressurized water tank 9 is provided on the outside of the outer cylinder 8, and the pressurized water tank 9 is connected to the atomizing nozzle 11 through the conduit 10. In this embodiment, when the dust generated by the drilling rig 4 during construction is large, the pressurized water tank 9 can be opened, and the water flows through the conduit 10 and is sprayed out from the atomizing nozzle to spray the dust during construction, thereby achieving the purpose of dust reduction treatment. In the past, the only way to deal with the dust problem generated during the construction process was to use a fog cannon for dust reduction. The fog cannon is large in size and requires external cables. During the construction process, it is manually moved to follow the movement of the drilling rig, and most of the construction sites are not hardened. Moving the fog cannon is time-consuming and laborious. By using this cleaning device, the spray range can be adjusted at any time according to the construction dust situation to achieve the construction dust reduction effect.

[0038] Preferably, the atomizing nozzle 11 is connected to the outer cylinder 8 via a fixing rod 12. In this embodiment, as the outer cylinder 8 rotates, the spraying range is wider, a better spraying effect is achieved, and a construction dust reduction effect is achieved.

[0039] The construction steps are as follows:

[0040] (1) During the assembly of the long spiral drilling rig, the cleaning device is fixed on the lower fixed bracket 7 of the drilling rig 4 in advance, and the bottom of the cleaning device is connected to the fixed bracket 7 through the base 6 to ensure the stability of the cleaning device during the cleaning process.

[0041] (2) The drill rod 4 penetrates the inner tube 2 and the fixed bracket 7 of the cleaning device at the same time.

[0042] (3) Drilling begins, and the drill rod 4 passes through the cleaning device when it goes down, and performs the first cleaning.

[0043] (4) After the drilling rig successfully drills a hole, the drill rod 4 is lifted, and the soil adhering to the drill rod 4 is cleaned again by passing through the cleaning device. A gap of 20-30 cm is left between the baffle plate 32 and the base 31 of the soil cleaning device to facilitate the discharge of the soil in the cleaning device, ensuring that the cleaning function is available regardless of whether the drilling rig is reversed or directly lifted.

[0044] (5) If dust occurs during the construction process, the pressurized water tank 9 can be opened for spraying, and the dust reduction effect can be achieved by adjusting the spray range.

[0045] The advantages and positive effects of the utility model are: impurities attached to the drill rod are cleaned in time by the baffle plate arranged on the inner side of the inner tube, and dust reduction treatment is performed on the dust generated during construction, thereby saving the labor cost of manually cleaning the soil attached to the drill rod during the construction process, avoiding safety problems such as falling objects from high altitude (soil on the drill rod falling from high altitude), and at the same time, dust reduction treatment is performed to protect workers from the influence of dust.

[0046] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
