Hydraulic ice raker

Abstract

The invention discloses a hydraulic ice raker; a pair of vertical tracks are oppositely arranged; the upper end of each track is provided with a hydraulic cylinder; the front end of a piston rod of the hydraulic cylinder faces downwards; the front end of the piston rod of each hydraulic cylinder is connected with the upper end of a pull rod in the corresponding track; the lower end of each pull rod is connected with a hydraulic motor; two ends of a rotary drum arranged between one pair of tracks are connected with a rotation shaft of the hydraulic motor; and more than two groups of rake pawls are arranged at the outer side of the rotary drum. The hydraulic ice raker is arranged at lock chambers at two sides of a gate in riverway fork; when an ice discharging brake at the rear side of the gate is closed and more floating ice accumulates on the water surface, the hydraulic cylinder drives the rotary drum to move to the water surface, the motor is started, the rake pawls on the rotating rotary drum can crush the floating ice in the lock chamber and push the floating ice to the ice discharging brake, and the accumulated floating ice can cross the ice discharging brake under the pushing of the rake pawls along with the continuous rotation of the rotary drum so as to fall to the downstream.

Description

technical field [0001] The invention relates to equipment for clearing lock chambers on both sides of gates in water conservancy projects and canal projects, in particular to a hydraulic ice rake machine for clearing floating ice in lock chambers in cold weather. Background technique [0002] In cold weather conditions, there will be ice floes in the lock chambers of water conservancy projects or canal projects. When the above-mentioned projects discharge or transport water, a large number of floating ice will cause the lock chambers to be blocked and the flow of water will not be smooth. At present, manual cleaning has been used to deal with the ice floes in the lock chamber, which has the problems of low labor efficiency, high labor intensity and poor work safety. Contents of the invention [0003] The object of the present invention is to provide a hydraulic ice raking machine, which can efficiently clean the floating ice in the lock chamber. [0004] In order to achie...

AI Technical Summary

Problems solved by technology

[0002] In cold weather, there will be ice floes in the lock chambers of water conservancy projects or channel projects. When the above projects discharge or transport water, a large number of floating ice will cause blockage of the lock chambers and poor flow of water.

At present, manual cleaning has been used to deal with the floating ice in the lock chamber, which has the problems of low labor efficiency, high labor intensity, and poor work safety.
