Disposer for removing rubbish adhered on spring flexible shaft and retracting method of spring flexible shaft of dredging trolley

Abstract

The invention discloses a disposer for removing rubbish adhered on a spring flexible shaft and a retracting method of the spring flexible shaft of a dredging trolley, and belongs to the technical field of pipeline dredging. The disposer for removing rubbish adhered on the spring flexible shaft comprises a support, a left shell, a right shell and a hook cutter assembly, wherein the left shell and the right shell are correspondingly arranged on the support, the hook cutter assembly is arranged in the left shell and the right shell, and a discharging channel is formed in the bottom of the left shell and the bottom of the right shell. The retracting method of the spring flexible shaft of the dredging trolley comprises the following steps that a power device of the dredging trolley is started to enable the spring flexible shaft to rotate reversely and roll back, and in the rolling process of the spring flexible shaft, the rubbish deposit carried in the spring flexible shaft is hooked under the action of hook cutters and discharged through the discharging channel to complete the retracting of the spring flexible shaft. According to the disposer and the retracting method, the rubbish can be prevented from being retained in the spring flexible shaft, so that the cleanliness of the spring flexible shaft and the pipeline dredging trolley is guaranteed, the spring flexible shaft and the pipeline dredging trolley are protected against the pollution and corrosion of the rubbish, the service life of the pipeline dredging trolley is further guaranteed and the maintenance frequency of the whole trolley is reduced.

Description

technical field

[0001] The invention belongs to the technical field of pipeline dredging, and in particular relates to a spring flexible shaft garbage adhesion processor and a recovery method for the spring flexible shaft of a wrecker truck. Background technique

[0002] The applicant's previous patent application for pipeline dredging wrecker-CN201310422518.X disclosed a device for dredging pipelines through a spring flexible shaft and a drill bit. During the dredging work, the spring flexible shaft is driven by the power of the wrecker truck. The obstacle sewage pipeline rotates forward rapidly, so as to dredging and cleaning the pipeline, and when the work is completed, it is reversed and exited. However, during the withdrawal of the spring flexible shaft, a large amount of garbage will be brought out from the inside of the flexible shaft spring and on the spring, which is adhered to the flexible shaft spring. This garbage is strongly adhered to the flexible shaft spring ...
