Abstract
The utility model belongs to the field of mining machines, and provides a scraper oil cylinder protecting device. The scraper oil cylinder protecting device comprises an oil cylinder, an oil cylinder support and an oil cylinder guard plate arranged above the oil cylinder. The oil cylinder support is movably connected with a piston rod of the oil cylinder. The oil cylinder support is provided with a guard plate support. One end of the oil cylinder guard plate is movably connected with the guard plate support. The other end of the oil cylinder guard plate is arranged on the upper portion of the oil cylinder in a lap joint mode. When the oil cylinder needs to be maintained, only the oil cylinder guard plate needs to be turned over to be away from the upper portion of the oil cylinder, and there is no need to detach the oil cylinder guard plate.
Description
Technical field
The utility model belongs to mining machinery field, relates to a kind of scraper cylinder protection device.
Background technology
At present, scraper working environment, in mine down-hole, due to underground work complex geologic conditions, sometimes has large rock mass and falls, and because ground condition is poor, slope is steep again, curved many, the phenomenon of likely can overturning; The dump cylinder of original scraper is directly exposed in working environment; the dump cylinder of scraper does not have protective device; often can be pounded by weights such as falling rocks, the surface of cylinder piston rod and oil sealing can suffer badly damaged, greatly shorten application life and the economy of oil cylinder.
Chinese patent CN200720071111.7 has announced a kind of cylinder protection device; this cylinder protection device reaches the object of protection oil cylinder by rotary ink tank guard shield is set above oil cylinder; but the rotary ink tank guard shield of this cylinder protection device is fixed on mark post holder; when maintenance oil cylinder, rotary ink tank guard shield need to be disassembled, for overhaul of the equipments is made troubles.
Utility model content
The purpose of this utility model is for problems of the prior art, does not need to dismantle the scraper cylinder protection device of oil cylinder backplate when a kind of maintenance is provided.
A kind of scraper cylinder protection device, comprise oil cylinder, cylinder support, be arranged on the oil cylinder backplate of oil cylinder top, described cylinder support is flexibly connected with the piston rod of oil cylinder, on described cylinder support, be provided with backplate bearing, one end of described oil cylinder backplate is flexibly connected with backplate bearing, and the other end of oil cylinder backplate is overlapped in oil cylinder top;
Described oil cylinder backplate is provided with bent plate near one end of backplate bearing, oil cylinder backplate reversion when prevention oil cylinder is worked under compared with high inclination-angle state;
The length of described oil cylinder backplate is not less than the length of piston rod, guarantees that oil cylinder backplate can not stretch out oversize dropping because of piston rod;
Described oil cylinder backplate is that bearing pin is connected with the flexible connection of backplate bearing.
The utlity model has following beneficial effect:
1. the one end due to oil cylinder backplate is flexibly connected with backplate bearing, and the other end of oil cylinder backplate is overlapped in oil cylinder top, when oil cylinder need to overhaul, only the upset of oil cylinder backplate need to be left to oil cylinder top, and not need oil cylinder backplate to dismantle.
2. the utility model is simple in structure, easy for installation, with low cost, economic and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of scraper cylinder protection device as shown in Figure 1; comprise oil cylinder 1, cylinder support 3, be arranged on the oil cylinder backplate 4 of oil cylinder 1 top; described cylinder support 3 is flexibly connected with the piston rod 2 of oil cylinder 1; on described cylinder support 3, be provided with backplate bearing 5; one end of described oil cylinder backplate 4 is connected by bearing pin with backplate bearing 5; the other end of oil cylinder backplate 4 is overlapped in oil cylinder 1 top; described oil cylinder backplate 4 is provided with bent plate 6 near one end of backplate bearing 5, and the length of described oil cylinder backplate 4 is not less than the length of piston rod 2.
When oil cylinder 1 needs repairing, 4 upsets of oil cylinder backplate are left to oil cylinder 1, then oil cylinder 1 is keeped in repair; When oil cylinder 1 work; the cylinder barrel of oil cylinder 1 protracts; expose the piston rod 2 being arranged in dump cylinder 1; oil cylinder backplate 4 is positioned at the stone of protecting piston rods 2 to avoid being dropped by top in piston rod 2 tops to be damaged; one end of oil cylinder backplate 4 is movably connected on backplate bearing 5, and the other end is overlapped on oil cylinder 1 top, while making oil cylinder 1 around cylinder support 3 motion; oil cylinder backplate 7 and oil cylinder 1 keeps synchronize, and when the bent plate 6 that is arranged on oil cylinder backplate 4 tail ends prevents oil cylinder 1 high inclination-angle work, oil cylinder backplate 7 reverses.
