Coiler and drill jumbo with same

Abstract

The invention discloses a coiler. The coiler comprises a fixing shaft, a roller and a guide wheel, wherein the roller is used for winding a pipeline, the guide wheel is used for winding a steel wire rope, the guide wheel and the roller are both rotatably arranged on the fixing shaft in a sleeve mode, and the guide wheel and the roller are detachably connected. According to the coiler, the guide wheel and the roller can be connected in a detachable manner and can be separated, so that the relative fixation of the guide wheel and the roller is guaranteed, and the guide wheel and the roller can rotate synchronously; the replacement performance of the guide wheel is also ensured, so that replacement with a new guide wheel is only needed after the local guide wheel is damaged, the whole rollerdoes not need to be replaced, the material cost is saved, the labor intensity is reduced, and the maintenance time is shortened; and in a preferred embodiment, the coiler is provided with a top anti-collision structure, and in another embodiment, the coiler can prevent the steel wire rope from falling off the guide wheel. The invention further discloses a drill jumbo with the coiler.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, and more specifically, to a pipe reel. In addition, the present invention also relates to a rock drilling jumbo comprising the above-mentioned hose reel. Background technique [0002] As a common tool for retracting and unwinding pipelines, the hose reel plays an important role in construction machinery and is usually used in various engineering equipment, such as rock drilling rigs. [0003] In the rock drilling jumbo, the hose reel is applied on the rock drilling machine propulsion beam to retract and release the oil pipe connected to the rock drilling machine. The hose reel usually includes a drum for winding the oil pipe. The drum is provided with a guide wheel for winding the wire rope. During the operation of the rock drilling jumbo, the cylinder of the rock drilling machine is used to drive the wire rope to rotate, and then the wire rope drives the drum to rotate. In order ...

AI Technical Summary

Problems solved by technology

[0004] However, as the use time increases, the wire rope is easy to loosen, and the rope skipping phenomenon often occurs, causing the guide wheel to be damaged.

After the guide wheel is damaged, the entire drum will not be usable, and the entire drum needs to be shut down to replace it

However, the replacement process of the drum is quite complicated, and the on-site replacement is very difficult, which not only affects the rock drilling efficiency, but also increases the maintenance cost. On the other hand, this will also lead to waste of materials and increase the engineering cost.
