Description
Technical Field
The utility model relates to a coal mining technical field, concretely relates to pipeline rust cleaning device in colliery.
Background
When the rust removing and paint brushing device is installed on a working surface under a coal mine, pipelines such as air pipes, water pipes, grouting pipes, water discharging pipes and the like of a track roadway and a transportation roadway need to be derusted and painted, pipelines of thousands of meters all need to be derusted manually, and the workload is quite large. Because the working environment and conditions in the pit are limited, workers all remove rust by means of a sickle in the past, and because the sickle is not a special tool for removing rust, the sickle is very inconvenient, wastes time and labor and has lower rust removal efficiency.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a simple structure, convenient operation can solve the colliery pipeline rust cleaning device of the inconvenient, time-consuming and energy-consuming problem of current rust cleaning instrument operation.
The utility model adopts the technical proposal that: a rust removing device for a coal mine underground pipeline comprises: the blade seat, the connecting rod, the push rod and the rust removing blade; the blade seat comprises an arc-shaped supporting plate and a base connected with one end of the supporting plate; one end of the connecting rod is connected with the base, and the other end of the connecting rod is connected with the push rod; blade clamping grooves are formed in two sides of the supporting plate; the rust removing blade is in an arc shape which is the same as the shape of the supporting plate, and can move along the blade clamping groove; the processing of the rust removing blade is arc-shaped, so that the contact area of the rust removing device and a pipeline is increased, and the rust removing speed can be improved.
Furthermore, the rust removing blade comprises a blade body and a blade edge, and the blade edge is provided with inclined fine sawteeth. When the sickle is used for derusting, the knife edge faces to the face of a worker, the worker applies force to scrape rust from outside to inside, the labor is high, the derusting blade is processed to be the knife edge to outside, and the worker uses thrust to push the derusting blade to remove rust, so that the labor is saved.
Furthermore, the connecting rod is formed by connecting a plurality of steel pipes in a threaded manner; a nut is welded on the surface of the base, a threaded hole is formed in the middle of the push rod, and the connecting rod is in threaded connection with the base and the push rod. The connecting rod of the rust removing device is designed into a detachable structure, so that workers can conveniently remove rust on a higher pipeline, and the application range is wider.
Furthermore, a layer of rubber anti-slip sleeve is arranged on the surface of the push rod, and anti-slip lines are arranged on the surface of the rubber anti-slip sleeve.
Compared with the prior art, the utility model has the following advantages: the utility model discloses simple structure, convenient operation can improve the efficiency that workman derusted in the pit, through designing the rust cleaning blade into detachable construction, the rust cleaning blade can change the rust cleaning blade and continue to use because of using for a long time to grind the blunt back, avoids the abandonment of whole rust cleaning device, has improved the life of equipment; in addition, the rust removing blade is processed into an arc shape, so that the contact area of the rust removing device and a pipeline is increased, and the rust removing efficiency can be improved; the connecting rod of the rust removing device is designed into a detachable structure, so that workers can conveniently remove rust on a higher pipeline, and the rust removing range is wider.
