Abstract
The utility model discloses an oil cylinder piston rod protector used on excavators and loaders. A protecting steel plate of which the length is a little longer than that of a piston rod is arranged above the piston rod and an oil cylinder. One end of the steel plate is fixed to the top end of the piston rod, and the other end of the steel plate is supported by a support frame fixed on the oil cylinder. Two rolling barrels by which the bar-shaped steel plate is clamped in parallel are arranged on the support frame for supporting the steel plate. When the piston rod extends and retracts in the oil cylinder, the steel plate at the upper end of the piston rod can extend and retract between the two rolling barrels backwards and forwards. An original device does not need to be changed. When the protector is additionally installed on a piston rod of an oil cylinder on the existing excavator or the existing loader, the protector can prevent the front surface of the piston rod of the oil cylinder from being knocked by stones or other heavy objects or from being shocked by high-voltage wires, so the surface damage of the piston rod is avoided. Therefore, oil leakage from an oil seal can not happen, the whole oil cylinder or the whole piston rod does not need to be replaced and unnecessary casualty loss is reduced.
Description
Technical field
The utility model relates to construction machinery product, specifically a kind ofly is applied to excavator, dress cuts the oil cylinder piston bar protective gear above the machine.
Background technique
Existing excavator, dress cut the oil cylinder piston bar unprotect device above the machine.During work because the electric shock that is subjected to the collision of stone or other weight or is subjected to high-tension busbar makes piston rod surface impaired, thereby cause the oil sealing leakage of oil, serious meeting causes oil cylinder inner wall impaired, can only change a whole set of oil cylinder or piston rod, oil sealing, spend thousands of units or tens thousand of unit, cause the very big loss of equipment and engineering.
The model utility content
The purpose of this utility model is to provide a kind of electric shock that can protect the oil cylinder piston bar can not be subjected to the collision of stone or other weight or be subjected to high-tension busbar to make the impaired oil cylinder piston bar protective gear of piston rod surface.
The technical solution of the utility model: above piston rod and oil cylinder, be provided with a block length and slightly be longer than piston rod and the protection steel plate parallel with piston rod; one end of steel plate is fixed on the piston rod top; the steel plate the other end supports by the support that is fixed on the oil cylinder; being provided with two cylinders above the support of supporting steel plate clamps the long strip steel plate is parallel; when piston rod is flexible in oil cylinder; the steel plate of piston rod upper end can be flexible back and forth between two cylinders; to reduce friction, steel plate is swung up and down.
The shape of described steel plate can be the long strip flat board, can be the rectangular curved plate of arc for cross section also.
The steel plate that is fixed on the protection piston rod on piston rod top can be fixed by support, and also the fastening piece of available other circular arc is fixed, also can be directly fixing at 1-2 screw rod of piston rod top welding or nut.
The support that is fixed on the piston rod top can be achieved like this: respectively be welded with one in steel plate one end two sides and be with semicircular iron hoop, other two bails are connected together by a steel pipe welding, flexibly connect and constitute two circle cards by two bails on screw rod and the long strip steel plate, two circles fasten on the piston rod top, and are fastening by screw rod.
The support that is fixed on the oil cylinder can be fixed on two iron plates on the oil cylinder by 2-4 root screw rod, connects two cylinders (steel pipe) between two iron plates, the movable support frame the when steel plate of formation protection piston rod is flexible back and forth.
Also can be supported on the oil cylinder by two semicircular iron hoops.The iron hoop upper end is connected with two cylinders (steel pipe) by polylith iron plate, the movable support frame the when steel plate of formation protection piston rod is flexible back and forth.
Also available other relevant mode constitutes the steel plate of the protection piston rod movable support frame when flexible back and forth.
The utility model does not change original equipment; as long as on have excavator now, adorn the oil cylinder piston bar that cuts above the machine, install this protective gear additional; the electric shock that just can protect the oil cylinder piston bar can not be subjected to the head-on crash of stone or other weight or be subjected to high-tension busbar makes piston rod surface impaired; thereby can not cause the oil sealing leakage of oil; do not need to change a whole set of oil cylinder or piston rod, oil sealing; prevent the fortuitous event generation, reduced unnecessary economic loss.
