Abstract
The utility model provides a mine equipment's oil cylinder piston rod protection device, including the cylinder, the cylinder links to each other with the piston rod, is equipped with the protection casing, and the bolt fastening is passed through on the articulated shaft of piston rod to protection casing one end, but pivoting, and the other end passes through the roller to be supported the card and on the cylinder, can roll on the cylinder, be equipped with big packing ring and spring washer between bolt and the articulated shaft, the roller supports bottom ann has the gyro wheel, the roller supports to symmetry setting. The utility model discloses how changing regardless of the oil cylinder piston rod stroke, can both protecting naked all piston rod surfaces, the mineral aggregate fish tail of avoiding being dropped, collide with or rub, the effective reliability service of long term of support equipment hydro -cylinder, is dismantled in a flexible way at its installation moreover, can not increase the maintenance degree of difficulty of equipment. The symmetry roller support to make the protection casing can follow the swing of hydro -cylinder closely, avoid when flexible moreover and the cylinder outer wall between the friction.
Description
Technical field
This utility model belongs to mine mechanism field, relates in particular to the oil cylinder piston rod protection device of a kind of mining equiment.
Background technology
At present, oil cylinder as one of most important executive component of mining equiment hydraulic system, is usually used in the lifting of operating mechanism, tumbles and flexible, trackless equipment the completing of function such as turn to.Owing to mining equiment design size, function restriction and oil cylinder installing space are compact, cause when many cylinder piston rods are direct or stretch out exposed outside, lack necessary protection and protection device；Even if some welds one piece of protective plate on cylinder barrel, but owing to the flexible stroke of oil cylinder is relatively big, also the piston rod stretched out cannot be formed and all be effectively protected, and cannot dismantle the maintenance that also have impact on equipment.And mine working condition is severe, underground work is on-the-spot narrow and the scope of operation is muddy jolts, mineral aggregate drops frequently in handling, transportation, it is easy to scratch, collide with or rub exposed piston rod surface.Surface damage on piston rod can quickly cause seal failure and the leakage of oil cylinder, affect mining equiment hydraulic system without normal operation, be greatly reduced oil cylinder service life and mining production efficiency.
Summary of the invention
This utility model provides the oil cylinder piston rod protection device of a kind of mining equiment to solve the problems referred to above.
The technical solution of the utility model is achieved in that the oil cylinder piston rod protection device of a kind of mining equiment; including cylinder barrel; cylinder barrel is connected with piston rod; it is provided with protective cover; protective cover one end is bolted on the jointed shaft of piston rod; can pivoting, the other end is stuck on cylinder barrel by roll support, can roll on cylinder barrel；
Large washer and spring washer it is provided with between described bolt and jointed shaft；
It is equipped with roller bottom described roll support；
Described roll support is for being symmetrical arranged.
The beneficial effects of the utility model are: no matter how the oil cylinder piston throw of lever changes this utility model, exposed all piston rod surfaces can be protected, avoid being dropped mineral aggregate to scratch, collide with or rub, effective reliability service during support equipment oil cylinder long, and it is installed, dismantles flexibly, will not increase the maintenance difficulty of equipment.Symmetrical roll support makes protective cover can follow the swing of oil cylinder closely, and friction when avoiding flexible and between cylinder barrel outer wall.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that the A-A of this utility model Fig. 1 is to structural representation.
Part illustrates: 1, jointed shaft, 2, large washer, 3, spring washer, 4, bolt, 5, piston rod, 6, protective cover, 7, cylinder barrel, 8, roll support.
Detailed description of the invention
In order to be more fully understood that and enforcement, below in conjunction with accompanying drawing, this utility model is further described: the oil cylinder piston rod protection device of a kind of mining equiment, including cylinder barrel 7, cylinder barrel 7 is connected with piston rod 5, protective cover 6 one end is fixed on the jointed shaft 1 of piston rod 5 by bolt 4, can rotate around jointed shaft, large washer 2 and spring washer 3 it is provided with between bolt 4 and jointed shaft 1, protective cover 6 other end utilizes deadweight by claiming the roll support 8 arranged to be stuck on cylinder barrel 7, protective cover 6 is made to swing with cylinder barrel 7 or slide along, protective cover 6 can change along with the change of cylinder piston rod 5 stroke, exposed all piston rod surfaces are effectively protected.It is equipped with roller, friction between protective cover 6 and cylinder barrel 7 outer wall when being avoided that flexible bottom roll support 8.
