Abstract
The utility model relates to a small arm oil cylinder protective device comprising a mechanical arm (1), an oil cylinder outer arm (2) and an oil cylinder inner arm (3) are arranged on the mechanical arm, a metal protective cover (4) is arranged on the periphery of the oil cylinder inner arm along the axial direction, the lower end of the metal protective cover is fixed at the lower end of the oil cylinder inner arm, a guide rail (5) is fixedly arranged on the inner wall of the metal protective cover, and the section of the guide rail is swallow-tail-shaped. A hold hoop (2-2) is arranged in the junction part (2-1) of the oil cylinder outer arm and the oil cylinder inner arm in a sleeved mode, a sliding block (2-3) fixedly provided with a dovetail groove is arranged on the side, close to the guide rail, of the hold hoop, and the sliding block is arranged on the guide rail in a sleeved mode. The length of the portion, matched with the sliding block with the dovetail groove, of the inner wall guide rail of the metal protective cover is larger than the piston stroke of an oil cylinder. The section of the metal protective cover is semi-circular. A hold hoop is fixedly arranged at the lower end of the oil cylinder inner arm, a fixed block provided with a dovetail groove is fixedly arranged on the hold hoop, and the fixed block and the guide rail are fixedly connected together. According to the small arm oil cylinder protective device, the hidden danger that the oil cylinder is crushed and damaged at work is avoided fundamentally, and effective protection of the oil cylinder is achieved.
Description
Technical field
The utility model relates to the forearm oil cylinder of engineering machinery, refers in particular to, and a kind of forearm oil cylinder protector belongs to engineering machinery auxiliary equipment technical field.
Background technology
In large-scale iron and steel enterprise, the engineering machinery of loading and unloading steel scrap mainly contains clamp machine, excavator and large-scale fork truck at present, in daily operation, because the part oil cylinder of mechanical arm is all exposed outside, site work environment is relative complex again, all kinds of wipings in separation operation and shipment steel scrap process are bumped unavoidable, and it is more frequent that the various hard thing bump that human operational error or mechanical breakdown and other reasons cause causes oil cylinder to damage phenomenon.From statistics, the project of reporting for repairment of this class engineering machinery mainly concentrates on damaging, wounding of various types of hardware, and wherein oil cylinder is the project of very easily damaging.Oil cylinder generally can't be repaired after being impacted and damaging, and the price of changing an import oil cylinder is about 30,000 yuan, and maintenance cost is high.Still incomparable at present effectively safeguard procedures suffer direct bump to avoid oil cylinder.
The utility model content
Technical problem to be solved in the utility model is a kind of forearm oil cylinder protector, can avoid materials such as oil cylinder and steel scrap to contact in operation process, realizes the purpose of protection oil cylinder.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of forearm oil cylinder protector comprises mechanical arm, and described mechanical arm is provided with oil cylinder outer arm and oil cylinder inner arm, it is characterized in that:
Described oil cylinder inner arm periphery is provided with protective cover vertically, and the lower end of described protective cover is fixed on the lower end of oil cylinder inner arm, and the inwall of protective cover is installed with the guide rail that the cross section is a swallow-tail form,
Be arranged with anchor ear on the joint portion of described oil cylinder outer arm and oil cylinder inner arm, a side of the close guide rail of described anchor ear sets firmly the slide block with dovetail groove, and described slide block set is located on the guide rail.
Further, according to the length of oil cylinder inner arm, the length of described guide rail and dovetail groove slide block coupling is greater than the piston stroke of oil cylinder.
As preferred version, the cross section of described protective cover is semicircle.
As preferably, the lower end of described oil cylinder inner arm is installed with anchor ear, sets firmly the slide block with dovetail groove on the anchor ear, and described slide block and guide rail are fixed together.
Operating principle of the present utility model is: be provided with protective cover vertically in oil cylinder inner arm periphery; during mechanical arm work; materials such as oil cylinder inner arm and steel scrap are isolated; the situation of having avoided oil cylinder to be bruised or having wounded takes place; and the slide block of oil cylinder inner arm and outer arm junction can move up and down along guide rail in the course of the work, has guaranteed the normal operation of mechanical arm.
Compared with prior art, the beneficial effects of the utility model are:
1, this device has fundamentally been avoided the oil cylinder hidden danger of wounded damage at work, has realized the effective protection to oil cylinder.
2, the cost of this device has only 500 yuan, compares the more price of renew oil cylinder (30,000 yuan), has saved maintenance cost greatly.
3, the regular maintenance to oil cylinder is convenient in this device easy installation and removal.
4, this device volume is moderate, does not influence driver's operation sight line.
5, the protective cover of this device has certain intensity, guarantees that all kinds of situation oil cylinders that occur in daily operation are not damaged.
