Description

Technical Field

[0001] This utility model belongs to the field of drill rod cleaning technology for roller cone drills, and specifically relates to a drill rod cleaning device for roller cone drills. Background Technology

[0002] Roller cone drills are mainly used in mining and other fields, and also have some applications in geological exploration. Cleaning the drill rod of a roller cone drill includes removing surface dirt, lubrication, and inspecting for cracks and wear.

[0003] After repeated use, drill pipes need to be removed and cleaned of dirt and other contaminants. This is usually done manually with a handheld hose to wash away the dirt, making the drill pipe easier to transport and use. However, this method of cleaning drill pipes is time-consuming and labor-intensive, impacting their usability.

[0004] Patent (publication number: CN218133521U) discloses a maintenance device for geological exploration drill rods. The device uses a rotating cleaning brush roller to perform rotational brushing, and the drill rod is pressed down by a clamping mechanism. Water is sprayed onto the drill rod for a period of time before the drill rod rotates, which improves the flushing efficiency. When cleaning and maintenance of the drill rod is required, manually pull the clamping mechanism upwards to place the drill rod between the two cleaning brush rollers, pressing it firmly against them. Clean water is then introduced into the equipment and sprayed from the spray nozzles onto the cleaning brush rollers, rinsing away dirt and other contaminants from the drill rod surface. The rinse water falls into the overflow tank below, accumulating and raising the water level. When the water level reaches the height of the level sensor, the controller activates the motor, causing the cleaning brush rollers to rotate, with different sides of the drill rod facing the spray nozzles for thorough rinsing and maintenance. All the rinsed wastewater falls into the wastewater collection tank for collection and treatment. After rinsing, the water supply is stopped. The cleaning brush rollers continue to rotate, and hot air can be sprayed from the hot air nozzles for drying. The wastewater level in the overflow tank drops until it falls below the level sensor, at which point the controller stops the motor, and the cleaning brush rollers stop rotating, allowing the drill rod to be safely removed.

[0005] The aforementioned patent has the following problems: When operators clean the drill rod, due to its heavy weight, it is inconvenient to directly lift the drill rod to the top of the cleaning brush roller when using a crane to lift it, as it is blocked by the top plate. Furthermore, the sewage containing mud after cleaning can easily clog the first and second sewage pipes. The water sprayed from the spray head can also easily cause water to splash on the surface of the drill rod, polluting the working environment. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a drill rod cleaning device for roller cone drilling rigs, which can effectively solve problems such as serious dust accumulation on drill rods, inconvenient cleaning, and pollution of the working environment.

The water inlet pipe 401 is fixedly connected to the water inlet of the arc-shaped water pipe. The sliding mechanism 5 includes two roller assemblies that are tactilely connected to the sliding frame 12. Each roller assembly includes a front roller frame 501, a rear roller frame 502, a transverse connecting plate 503 connecting the two roller frames, and an L-shaped connecting rod 504.

[0021] The roller drive mechanism 505 of this utility model includes a drive motor 5051, a drive gear 5052, a driven gear 5053, and a first bevel gear 5054. The drive motor frame is fixedly installed on the upper end of the front roller frame 501. The drive gear 5052 is connected to the output shaft of the drive motor 5051.

The two roller assemblies symmetrically arranged on the base 1 reciprocate left and right on the sliding frame 11 under the drive of the roller drive mechanism, thereby driving the cleaning mechanism 4 to move left and right on the sliding frame 12.

[0022] The wastewater tank 2 of this invention has a constricted opening on one side, and the bottom surface of the tank slopes downwards on one side. The wastewater tank 5 is made of stainless steel, and its inner wall is coated with an anti-stick coating. This effectively prevents impurities in the wastewater from adhering, facilitating the discharge of wastewater containing mud.

[0023] The support wheel assembly 32 of this utility model consists of two support wheel components mounted on each gantry 31. Each support wheel assembly comprises a support base 321 and two support wheels 322 with internal bearings. The support bases 321 are fixed to the two gantry 31 respectively, and the two support wheels 322 are rotatably mounted on the top of the support base 321. The two support wheel assemblies provide rotational support for the drill rod body 6 of the rotary drill. By setting an open-top sewage tank 2, the arc-shaped cover blocks splashing sewage, allowing sewage to smoothly enter the interior of the sewage tank. The sewage tank, which is inclined and has an inner wall coated with an anti-stick coating, can smoothly guide and discharge sewage containing mud, facilitating subsequent sewage treatment.

[0024] The working principle of this utility model: By setting up a movable cleaning mechanism, when the cleaning mechanism is moved to the right side of the base plate, the top space of the support wheel is open, which facilitates the use of external hoisting equipment to lift the heavy roller drill rod body 6 to the top of the support wheel 32. This allows the arc-shaped tube 303 to move without obstructing the support wheel 32, making the top space of the support wheel 32 open. At this time, the use of external hoisting equipment to lift the roller drill rod body 6 to the top of the support wheel 32 solves the problem in the prior art that when cleaning the drill rod, the heavy weight of the drill rod is obstructed by the top plate, making it inconvenient to lift the drill rod to the top of the cleaning brush roller.

[0025] The support wheel assembly 32 of this utility model consists of two support wheel components mounted on each gantry 31. Each support wheel assembly consists of two support seats 321 and two support wheels 322 with internal bearings. The support seats 321 are fixed on the two gantry 31 respectively, and the two support wheels 322 are rolled on the top of the support seats 321 respectively. The two support wheel assemblies provide rotational support for the drill rod body 6 of the rotary drill. Then, an external high-pressure water source is connected to the water inlet pipe 401 to provide high-pressure water flow for cleaning the drill rod body 6 of the rotary drill. Then, the drive motor 5051 is controlled by an external controller to work. The roller drive mechanism drives the sliding frame 11 to roll back and forth, thereby driving the cleaning mechanism 4 to move left and right on the sliding frame 12, so that the arc-shaped pipe can be moved. As the 403 moves, the inlet pipe 401 delivers high-pressure water to the arc-shaped pipe 403, and then sprays high-pressure water through several nozzles 404 to wash away dirt and other impurities on the surface of the drill rod body 6 of the rotary drill. The arc-shaped cover 402 surrounds the nozzles 404, effectively preventing sewage from splashing and allowing the sewage to fall into the inclined sewage tank 2. As the arc-shaped pipe 403 moves, the nozzles 404 can wash different parts of the drill rod body 6 of the rotary drill. The cleaned sewage flows into the sewage tank 2 through the obstruction of the arc-shaped cover 402. The support block 11 at the bottom of the sewage tank 2 tilts the sewage tank 2 onto the base plate 1. The sewage tank 2 is made of stainless steel and the inner wall is coated with an anti-stick coating, which can effectively prevent impurities in the sewage from adhering and facilitate the discharge of sewage containing mud.
