The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] like Figure 1 As shown, the present invention provides a thread cleaning device, which is used for cleaning the internal and external threads at the end of a petroleum casing. The thread cleaning device comprises: a thread cleaning mechanism, a positioning mechanism, a frame and a control console; the frame is fixedly arranged on the ground, the positioning mechanism is arranged on the frame, the positioning mechanism can drive the petroleum casing to the thread cleaning mechanism, the thread cleaning mechanisms can be movably arranged at both ends of the frame, the thread cleaning mechanism can clean the internal and external threads at the end of the petroleum casing, and the control console is electrically connected to the thread cleaning mechanism and the positioning mechanism.

[0042] In this embodiment, the thread cleaning device is provided at both ends of the frame through the thread cleaning mechanism so that the thread cleaning device can clean the oil casing located on the frame, avoiding the traditional cleaning of both ends of the oil casing by multiple workers, saving labor costs, improving cleaning efficiency, and improving cleaning quality. And the structural setting of the thread cleaning mechanism can prevent the splashing of cleaning liquid and cleaning oil during the cleaning process. Furthermore, in order to make the cleaning of the oil casing more convenient, the thread cleaning device is provided with a positioning mechanism on the frame, and the oil casing on the frame is transferred by the positioning mechanism, so that the oil casing placed on the frame can be accurately and stably transferred to the thread cleaning mechanism, further improving the cleaning efficiency of the thread cleaning device and avoiding the inconvenience of transferring the oil casing.

[0043] See also Figure 1 and Figure 2 The thread cleaning mechanism includes a male end cleaning component 1, a female end cleaning component 2, a recovery component 3 and a walking component; the male end cleaning component 1 and the female end cleaning component 2 are connected to the recovery component 3 to recover the cleaned oil and cleaning liquid, the male end cleaning component 1, the female end cleaning component 2, and the recovery component 3 are all arranged on the walking component, and the male end cleaning component 1, the female end cleaning component 2, and the walking component are all electrically connected to the control console.

[0044] In this embodiment, the male end cleaning component 1 and the female end cleaning component 2 are correspondingly arranged on both sides of the frame, so that the oil casing located at the cleaning station on the frame can clean the male end thread and the female end thread at the same time, which greatly improves the cleaning efficiency of the oil casing. The setting of the recovery component 3 enables the thread cleaning device to complete the recovery of oil stains and cleaning liquid at the same time during the cleaning process, avoiding the process of manual cleaning and recovery of oil stains after cleaning, saving labor, reducing labor costs, and improving the economy of the device. Furthermore, the setting of the walking component enables the thread cleaning mechanism to adaptively adjust the cleaning positions of the male end cleaning component 1 and the female end cleaning component 2 according to the different lengths of the oil casing, thereby improving the applicability of the device.

[0045] The male end cleaning component 1 includes a cylindrical brush head 11, a brush head height adjustment member 12 and a cleaning liquid injection member; the brush head height adjustment member 12 is fixedly arranged on the walking component, the cylindrical brush head 11 is arranged at the output end of the brush head height adjustment member 12, and the cleaning liquid injection member is arranged in the cylindrical brush head 11. When the cylindrical brush head 11 abuts against the oil casing, the cleaning liquid injection member outputs cleaning liquid to the oil casing, and the cleaning liquid output by the cleaning liquid injection member can be recovered through the recovery component 3.

[0046] The female end cleaning component 2 includes a scrub brush head 21, a brush head telescopic rod 22 and a cleaning liquid spray component; the brush head telescopic rod 22 is fixedly arranged on the walking component, the scrub brush head 21 is arranged at the output end of the brush head telescopic rod 22, and the cleaning liquid spray component is arranged in the scrub brush head 21. When the scrub brush head 21 abuts against the oil casing, the cleaning liquid spray component outputs cleaning liquid to the oil casing, and the cleaning liquid output by the cleaning liquid spray component can be recovered through the recovery component 3.

[0047] In this embodiment, brush heads of different shapes are arranged in the male end cleaning component 1 and the female end cleaning component 2 to facilitate cleaning of the internal and external threads of the oil casing. In the thread cleaning mechanism, the male end cleaning component 1 cleans the external threads of the oil casing through the cylindrical brush head 11, and in the thread cleaning mechanism, the female end cleaning component 2 cleans the internal threads of the oil casing through the set plate brush. The brush heads of different shapes can achieve a better cleaning effect on the internal and external threads at both ends of the oil casing.

[0048] Moreover, the cleaning liquid spraying member is arranged on the surface of the brush head so that when the brush head contacts the surface of the oil casing, the cleaning liquid can be immediately sprayed on the surface of the oil casing, which not only improves the cleaning quality of the oil casing, but also reduces the labor intensity of the staff. There is no need for the staff to repeatedly spray the cleaning liquid, which reduces the labor cost and improves the cleaning efficiency.

[0049] In one embodiment, the cleaning liquid injection device includes: a cleaning liquid nozzle, a self-priming pump and a cleaning liquid storage box. The cleaning liquid nozzle is installed on the inner surface of the brush head. The cleaning liquid nozzle is connected to the cleaning liquid storage box placed outside the frame through the self-priming pump. In addition, the brush head telescopic rod 22 includes a driving motor and a telescopic rod. The driving motor is arranged on the walking assembly. The driving motor drives the telescopic rod to extend and retract so that the brush head can go deep into the oil casing for cleaning. The brush head height adjustment member 12 includes a bracket, a screw rod and a driving member. The bracket is fixedly arranged on the walking assembly. The bracket is provided with a threaded hole matching the screw rod. The driving member is installed on the bracket and connected to the screw rod through the threaded hole to drive the screw rod to reciprocate in the height direction of the bracket. A mounting plate is arranged on the side of the bracket close to the brush head. The mounting plate is fixedly connected to the screw rod. The cylindrical brush head 11 is arranged on the mounting plate.

[0050] In a preferred embodiment, the threaded cleaning mechanism also includes a pair of brush head rotating parts 4, the brush head telescopic rod 22 in the female end cleaning component 2 is fixedly mounted on one of the brush head rotating parts 4, and the other brush head rotating part 4 is mounted on the brush head height adjustment part 12 of the male end cleaning component 1 to adjust the height position of the cylindrical brush head 11.

[0051] See also Figure 3The recovery component 3 includes a recovery cover 31, a recovery tank 32 and a recovery bucket; the recovery cover 31 is arranged outside the male end cleaning component 1 and the female end cleaning component 2, the recovery tank 32 is arranged below the male end cleaning component 1 and the female end cleaning component 2 and abuts against the inner wall of the recovery cover 31 to recover the cleaning liquid and oil splashed during the cleaning process, and the recovery tank 32 is connected to the recovery bucket. The walking component includes a frame and at least four walking wheels; the male end cleaning component 1, the female end cleaning component 2, and the recovery component 3 are all arranged on the frame, the frame is connected to the walking wheels, and the walking wheels are rollingly connected to the frame.

[0052] In a preferred embodiment, the positioning mechanism includes a rotating roller, a longitudinal adjustment roller and a work position sensor; the rotating roller is arranged on the frame to transmit the oil casing and the rotating roller is perpendicular to the frame of the frame, the longitudinal adjustment roller is arranged on the frame to adjust the position of the oil casing and the longitudinal adjustment roller is parallel to the frame of the frame, and a pair of work position sensors are arranged at the corresponding thread cleaning mechanism of the frame to adjust the thread cleaning mechanism according to the position of the oil casing detected by the work position sensor, and the work position sensor, rotating roller and longitudinal adjustment roller are all electrically connected to the control console.

[0053] In this embodiment, the setting of the rotating roller in the positioning mechanism makes it unnecessary for the staff to manually carry the oil casing on the frame. The oil casing to be cleaned and the cleaned oil casing are transferred by the rotating roller, thereby realizing continuous cleaning of the oil casing and greatly improving the cleaning efficiency. The setting of the longitudinal adjustment roller further facilitates the alignment of the ends of the oil casing, avoiding the movement of the rotating roller during the transportation process, which causes the oil casing to be unable to align with the cleaning mechanism. In addition, the station sensor can be an infrared sensor or a pressure sensor. When the station sensor senses the position of the oil casing, the oil casing is adjusted by the rotating roller and the longitudinal adjustment roller so that the oil casing is aligned with the brush head of the cleaning mechanism, further ensuring the cleaning quality and avoiding the low cleaning quality caused by the position deviation of the oil casing.

[0054] In a preferred embodiment, the control console includes a PLC console, which is installed on the thread cleaning mechanism, and the PLC console is electrically connected to the positioning mechanism and the thread cleaning mechanism to control the transportation and cleaning of the oil casing.

[0055] Moreover, for products with heavy oil pollution, the thread cleaning device can realize two cleaning processes of rough cleaning and fine cleaning, and can self-clean the brush head to ensure the cleaning effect. Every equipment action in the whole process can be automatically controlled by the control panel.
