Description

Technical Field

[0001] The utility model belongs to the technical field of mud cleaning equipment, and in particular relates to a dredging power head device. Background Art

[0002] In drilling and other operations, it is often necessary to clean the sediment inside the mud tank. The traditional operation method is for workers to enter the mud tank, use basins and buckets to scoop out the thin and thick sediments, and use shovels to shovel out the harder sediments. Due to the limited space inside the mud tank, polluted air, and harsh working environment, it is difficult to work in the tank for a long time, so there are problems such as poor cleaning effect and low cleaning efficiency. At the same time, the harmful gases generated by the mud in the tank during work affect the safety of the workers, which ultimately makes the cleaning of the mud tank very cumbersome.

[0003] In the existing mud cleaning equipment in the tank, the negative pressure adsorption head device uses a negative pressure straw to clean the mud. As time goes by, the mud will settle and harden. The existing mud adsorption head device is a negative pressure straw, and the hardened block-shaped soil often easily blocks the pipe, resulting in poor mud cleaning effect. At the same time, the existing mud cleaning equipment needs to extend the head of the hose into various places inside the mud tank through external equipment, which is difficult to operate and inefficient. At the same time, the suction pipe used in the existing equipment is a rubber hose that can withstand high pressure, with a diameter of DN100 and a length of about 50 meters, which is very bulky. It is difficult to operate by manually moving it outside the tank by manpower. Therefore, when cleaning the mud in the tank, there is an urgent need for a dredging power head device that can break the hardened soil and can perform cleaning in multiple directions in the tank.

The driving module 62 includes a driving box 620, and a driving box partition is provided inside the driving box 620. The driving box partition divides the driving box 620 into a first cavity and a second cavity. A driving pneumatic motor 621 is installed in the first cavity. A driving sprocket 622 is installed on the side of the driving box 620. The driving sprocket 622 is sleeved on the end of the rotating shaft of the driving pneumatic motor 621. When the driving pneumatic motor 621 is working, the driving sprocket 622 is driven to rotate. A box negative pressure suction pipe 623 is installed on the top of the driving box 620. The box negative pressure suction pipe 623 is connected to the first cavity. A box lifting cylinder 624 is installed at the end of the driving box 620. The end of the piston rod of the box lifting cylinder 624 is connected to a lifting box connecting rod 625. The end of the lifting box connecting rod 625 is fixedly connected to the dredging box 610.

[0021] In this embodiment, the dredging pneumatic motor 611, the driving pneumatic motor 621, the box negative pressure suction pipe 623 and the box lifting cylinder 624 are all connected to the existing air source equipment. The air source equipment includes an air compressor, etc., which can generate vacuum adsorption force and high-pressure thrust. The air source equipment is connected to the dredging pneumatic motor 611, the driving pneumatic motor 621 and the box negative pressure suction pipe 623 through pipelines to control the operation of the dredging pneumatic motor 611, the driving pneumatic motor 621 and the box negative pressure suction pipe 623 respectively.

[0022] The mud to be cleaned is discharged or recovered through the box negative pressure suction pipe 623 under the combined action of the dredging spiral cutter 612 and the air adsorption force in the box negative pressure suction pipe 623.

[0023] The driving pneumatic motor 621 and the driving sprocket 622 constitute a set of driving devices. Two driving devices are installed in parallel in the driving box 620. The adjacent driving devices are connected by a chain 627. The chain 627 includes a chain inner section 6271 and a chain outer section 6272 that are fixed together. The chain inner section 6271 is sleeved on the driving sprocket 622 and meshed. The cross section of the chain outer section 6272 is "U" shaped. By arranging the "U" shaped chain outer section 6272 outside the chain inner section 6271, the chain 627 can better grasp the ground during movement, increase stability, and will not slip.

[0024] The utility model drives the pneumatic motor 621 to drive the driving sprocket 622 to rotate, thereby causing the chain 627 to move, thereby driving the entire device to move.

[0025] A tensioning device 626 is installed on the side of the driving box 620, and the tensioning device 626 includes a tensioning fixed block 6261, a tensioning slider 6262 and a tensioning wheel 6263.

[0026] During use of the utility model, if the chain 627 becomes loose, the position of the tensioning wheel 6263 can be adjusted to make the tensioning wheel 6263 mesh with the chain 627, thereby supporting the chain 627 and putting the chain 627 in a tensioned state.

[0027] The tensioning block 6261 is provided with a threaded hole, and the tensioning slider 6262 is a rectangular plate-shaped structure. The tensioning slider 6262 is provided with two parallel waist-shaped holes along the long side direction, and a bolt is inserted into the waist-shaped hole. The end of the bolt passes through the waist-shaped hole and cooperates with the threaded hole on the tensioning block 6261, thereby fixing the tensioning slider 6262 to the tensioning block 6261. When the position of the tensioning slider 6262 needs to be adjusted, it is only necessary to loosen the bolt, adjust the position of the bolt in the waist-shaped hole, and then fix it, thereby completing the position adjustment of the tensioning slider 6262. A rotating shaft is inserted into the center of the tensioning wheel 6263, and the rotating shaft is fixedly connected to the end of the tensioning slider 6262, thereby enabling the tensioning wheel 6263 to rotate around the rotating shaft.

[0028] A driving box guide rod 6201 is installed at the front end of the driving box 620, and a dredging box guide piece 6101 is provided on the dredging box 610.
