(2) technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic pressure shoving rake, its structure comprise claw box frame frame, the claw that is positioned at frame front and roller, are positioned at oil cylinder, hydraulic station on the oil cylinder hold-down support of frame rear portion; Described oil cylinder front end connects hydraulic station by high-pressure oil pipe, and the rear end is connected on the claw by the oil cylinder plunger; Described hydraulic station control oil cylinder drives the claw that is connected on the claw oil cylinder plunger and moves around.
The roller of described frame front is divided into two-layer being installed on the roller bracket up and down; Roller is installed on the upper strata one, the parallel installation eight road rollers of lower floor, and claw lies in the middle of the two-layer roller.
Described claw front end is made outer case with heat-resisting steel sheet and plate, and the inner kilneye of filling waters material feeding; The claw rear end is separated into two parts, is welded into box frame; The front portion of described oil cylinder is placed in the middle of the two-box type framework, is fixed on the claw outer case at front end oil cylinder plunger, and the rear end is fixed on the frame.
Described hydraulic station with the claw frame separately is positioned on the fuel tank, is connecting Oil pump electrical machinery and oil pump by pressure piping.
Described hydraulic station adopts the inserted valve hydraulic system and changes the stretching out and withdraw of opening sequence control claw oil cylinder plunger of inserted valve by electric-control system.
(3) beneficial effect
A kind of hydraulic pressure shoving rake of the present utility model is compared with prior art, has following beneficial effect:
The utility model is reasonable in design, simple in structure, adopt this device can be implemented in high temperature chamotte appearance heap " snowman " phenomenon on the grate cooler, guarantee under the rotary kiln normal operation, by workman's remote-controlled operation button, just can push the material of accumulation timely and effectively open.After solution need stop the kiln cooling in the past, disclose the long-pending material of reactor startup with club by the workman.And the workman is when operation, and in the face of the high heat of high temperature, security and environment is relatively poor in the past causes the problem of personal injury easily.

The specific embodiment
Next explain below with reference to Figure of description a kind of hydraulic pressure shoving rake of the present utility model being done.
A kind of hydraulic pressure shoving rake of the present utility model, its structure comprise claw box frame frame, the claw that is positioned at frame front and roller, are positioned at oil cylinder, hydraulic station on the oil cylinder hold-down support of frame rear portion; Described oil cylinder front end connects hydraulic station by high-pressure oil pipe, and the rear end is connected on the claw by the oil cylinder plunger; Described hydraulic station control oil cylinder drives the claw that is connected on the claw oil cylinder plunger and moves around.Described hydraulic station with the claw frame separately is positioned on the fuel tank, is connecting Oil pump electrical machinery and oil pump by pressure piping.Described hydraulic station adopts the inserted valve hydraulic system and changes the stretching out and withdraw of opening sequence control claw oil cylinder plunger of inserted valve by electric-control system.
Roller bracket 2 is welded on claw box frame frame 1 front portion, have 8 roads " U " shape notch on the roller bracket 2, lower floor's roller 3 parallel cards are in roller bracket 2 " U " shape notch, weld out with band steel by angle steel at roller bracket 2 middle parts, have " U " shape notch support equally, roller 4 same parallel cards in upper strata screw in " U " on roller bracket 2 tops shape notch.Claw 5 lies in the middle of the two-layer roller.
Separately shelve with claw frame 2 at hydraulic cartridge valve station 11, and the twice pressure piping connects A mouth 15 connections, the oil cylinder 6 cavity of resorption oil connections 8 of oil cylinder 6 epicoele oil connections 7 with inserted valve station 11 respectively with the B mouth 16 at inserted valve station 11.
During operation, press the start button on the electric cabinet 17, Oil pump electrical machinery 13 drives oil pump 12 rotations, and the hydraulic oil in the fuel tank 14 is squeezed in the inserted valve station 11.Press the forwarding button on the electric cabinet 17, hydraulic oil is from B mouth 16 output at inserted valve station 11, enters the cavity of resorption of oil cylinder 6 by pressure piping, and the oil cylinder plunger 9 in the oil cylinder 6 stretches out, and promotes claw 5 and moves ahead, and pushes the material thing of piling up on the grate plate of front open.Press the back on the electric cabinet 17, hydraulic oil is from A mouth 15 output at inserted valve station 11, enters the epicoele of oil cylinder 6 by pressure piping, and oil cylinder plunger 9 withdrawals in the oil cylinder 6 drive claw 5 and return in the frame.Because claw 5 fastened fixing between upper strata roller 4 and the lower floor's roller 3, when claw 5 seesaws, define claw 5 and go here and there movingly up and down, simultaneously owing to the rolling of roller, reduced the frictional resistance of claw.
The above embodiment is a kind of of the more preferably concrete embodiment of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
