Abstract
A quick dismounting mechanism for a hydraulic oil cylinder in a telescopic machine tail is characterized in that a pushing movable base of the telescopic machine tail is connected with the hydraulic oil cylinder through a pin shaft I, the other end of the hydraulic oil cylinder is connected and fixed with a groove supporting base through a pin shaft II; and the pin shaft I is arranged in the horizontal direction and is vertical to the axis of the hydraulic oil cylinder. With the adoption of the technical scheme, as the pin shaft of the quick dismounting mechanism is arranged in the horizontal direction, the hydraulic oil cylinder can be taken out in the vertical direction after the pin shaft is taken out, so that the hydraulic oil cylinder can pass through the clearance between a power part of a scraper conveyor and a machine tail frame smoothly without dismounting the power part. The quick dismounting mechanism can carry out the quick dismounting when the hydraulic oil cylinder is dismounted off the scraper conveyor, so that the labor intensity is reduced, and the high production and the efficiency of a coal mine can be guaranteed.
Description
Technical field
The utility model relates to the improvement to slat conveyer, specifically relates to the improvement to dismounting hydraulic ram mechanism in the slat conveyer tail position.
Background technology
The hydraulically extensible tail is mainly used in the tensioning of coal mine work area slat conveyer scraper chain.In general, hydraulic ram is arranged between slat conveyer power part and the aircraft tail shelf.Long-term use finds that hydraulic ram often goes wrong, so need often maintenance or replacing.Because passing seat, in the past flexible tail connects hydraulic ram by the vertical direction bearing pin; When needing the dismounting hydraulic ram; After the bearing pin dismounting, at first need the hydraulic ram level be pulled upwardly, the parts that lift the back power part just block hydraulic actuating cylinder; Thereby can not hydraulic actuating cylinder be taken out, need could take out hydraulic ram after the dismounting power part earlier.Because power part weight is big, the down-hole dismounting is more difficult, and needs should avoid by engine request for a long time as far as possible, so brought inconvenience for the coal mining work of down-hole.
Summary of the invention
The purpose of the utility model provides a kind of quickly dismantled hydraulically extensible tail of convenient for maintaining.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises that flexible tail passing seat connects hydraulic ram through the bearing pin I, and the hydraulic ram other end connects the hold down groove supporting seat by the bearing pin II, and said bearing pin I is provided with in horizontal direction, and perpendicular to the hydraulic ram axis.
The bearing pin II also is provided with in horizontal direction.
Adopt the utility model of technique scheme; Place because bearing pin is a horizontal direction, take out after the bearing pin, can vertical direction take out hydraulic ram; Make hydraulic ram from the gap between slat conveyer power part and the aircraft tail shelf, to pass through smoothly, need not dismantle power part.The utility model can be realized fast assembling-disassembling when slat conveyer dismounting hydraulic ram, reduced labour intensity, has guaranteed the colliery high-yield and high-efficiency.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
The specific embodiment
At first the direction of the utility model is like this definition: be as the criterion to keep flat paper, parallel and paper be horizontal motion, what vertically pass paper is perpendicular movement.
As shown in Figure 1, in the utility model, it is U type seat that flexible tail is passed seat 5, and flexible tail is passed seat 5 and connected hydraulic ram 2 through bearing pin I 1, and hydraulic ram 2 other ends connect hold down groove supporting seat 4 by bearing pin II 3.
For when keeping in repair hydraulic actuating cylinder, do not dismantle power part, the utility model is provided with bearing pin I 1 in horizontal direction, and perpendicular to the hydraulic ram axis.Simultaneously, bearing pin II 3 also is provided with in horizontal direction.That is: under these circumstances, hydraulic ram 2 needs half-twist when mounted.
Claims (2)
1. flexible tail hydraulic actuating cylinder fast assembly and disassembly mechanism; Comprise that flexible tail passing seat (5) connects hydraulic ram (2) through bearing pin I (1); Hydraulic ram (2) other end connects hold down groove supporting seat (4) by bearing pin II (3); It is characterized in that: said bearing pin I (1) is provided with in horizontal direction, and perpendicular to the hydraulic ram axis.
