Description

Underground pipeline dredging equipment Technical Field The utility model relates to the technical field of underground pipeline dredging, in particular to underground pipeline dredging equipment. Background In underground pipeline dredging operation, different equipment combinations are usually selected according to pipeline types, blocking degrees and operation environments, and common equipment comprises a high-pressure cleaning machine/vehicle, a sewage suction truck, a spring dredging machine, a steel rope dredging machine, a push rod dredging machine, a CCTV pipeline detection robot, pneumatic dredging equipment, chemical dredging equipment and the like. The high-pressure flushing nozzle, or water mouse, special nozzle for pipeline, pipeline dredging nozzle, pipeline flushing head, etc. is the most important part of high-pressure cleaner/vehicle, and is mainly characterized by that it utilizes high-pressure pump and pipeline to supply water, then the nozzle of tail portion or head portion of the nozzle can spray high-pressure water flow to flush interior of pipeline, so that the impurity of sludge, etc. can be loosely stripped and washed away so as to attain the effect of dredging pipeline. The existing high-pressure flushing spray head is generally made of tungsten carbide, ceramic or stainless steel materials, the tungsten carbide is mainly used for the spray nozzle to bear the impact of high-pressure water flow, the stainless steel is mainly used as a spray head shell, the spray head needs to be moved in a pipeline to increase the flushing area of the pipeline, the spray head needs to be contacted and rubbed with the inner wall of the pipeline and sediment when moving, the spray head is easy to wear and needs to be replaced frequently, structures such as a water channel and a tungsten carbide spray nozzle are arranged in the spray head, and replacement cost is high. Disclosure of utility model Based on this, the present utility model aims to provide an underground pipeline dredging device, so as to solve the technical problems mentioned in the background art. In order to achieve the purpose, the underground pipeline dredging device comprises a device main body, wherein supports are connected below two sides of the device main body, limiting plates are connected to the bottoms of the two supports, a plurality of insertion holes are formed in one side of the tops of the two limiting plates, a plurality of bolts penetrate through one side of the tops of the two supports, one ends of the bolts are connected with bolts, two supporting rods are connected between the bolts and the two limiting plates respectively, and clamping grooves are formed in the two supporting rods.
