Abstract
The utility model discloses a supporting fixing structure of a telescopic oil cylinder. A telescopic arm (1) is sleeved in a basic arm (2). Two ear rings of the telescopic arm (3) are respectively hinged with a base on the telescopic arm (1) and the basic arm (2). One end of the telescopic cylinder (3), which is next to a piston rod, is fixedly provided with a supporting frame (5). The supporting frame (5) is fixedly provided with a sliding shoe (4) which slidably contacts with the inner wall of the telescopic arm (1). The supporting fixing structure of the utility model has the advantages of: convenient installation, high guiding performance, strong stability, increased efficiency in the production and operation process of machineshop truck, and prolonged service life of the telescopic oil cylinder.
Description
Technical field
The utility model relates to a kind of support fixed structure of telescopic oil cylinder.
Background technique
Telescopic boom is the main actuator of hoist lifting weight, material adopts the low-alloy high-strength steel plate welding with big bending rigidity to make the Thin walled Box structure, load capacity is very big, the armed lever that is sleeved in the basic arm can freely be stretched by oil hydraulic cylinder control, satisfies the needs of different hoisting heights.
Telescopic boom also is widely used in engineering machinery such as telescopic boom excavator, forklift truck, fork truck, truck-mounted crane now except that being used for hoist, also more and more higher for every performance requirement of telescopic boom.Telescopic boom, telescopic oil cylinder etc. are installed in the basic arm, and when telescopic oil cylinder stretched by oil-feed and oil extraction, telescopic boom can stretch out in basic arm or regain.
The effect of telescopic oil cylinder is the length that changes telescopic boom, and bears up weight, the caused thrust load of telescopic boom weight and other external force.Present telescopic oil cylinder is because two earrings of telescopic oil cylinder are hinged on respectively on the bearing on telescopic boom and the basic arm, and the telescopic oil cylinder middle part is unsettled, and it assemble inconvenience, and guidance quality is not high, poor stability, thus have influence on working life of telescopic oil cylinder.
The model utility content
Technical problem to be solved in the utility model provides a kind of easy to assembly, the guidance quality height, and stability is strong, can increase work efficiency in engineering truck production and working procedure, and can improve the support fixed structure of telescopic oil cylinder in the working life of telescopic oil cylinder.
In order to solve the problems of the technologies described above, the support fixed structure of the telescopic oil cylinder that the present invention adopts, telescopic boom is enclosed within the basic arm, two earrings of telescopic oil cylinder are hinged on respectively on the bearing on telescopic boom and the basic arm, an end that closes on its piston rod on described telescopic oil cylinder is fixed with supporting frame, on described supporting frame, be fixed with piston shoes, the inwall sliding contact of described piston shoes and described telescopic boom.
Adopt the support fixed structure of the telescopic oil cylinder of technique scheme, be fixed with supporting frame owing on telescopic oil cylinder, close on an end of its piston rod, on supporting frame, be fixed with piston shoes, it is unsettled that the inwall sliding contact of piston shoes and telescopic boom, supporting frame and piston shoes are supported telescopic oil cylinder middle part not have, and makes the easy to assembly of telescopic oil cylinder, the guidance quality height, stability is strong, in engineering truck production and working procedure, can increase work efficiency, thus the working life of improving telescopic oil cylinder.
In sum, the utility model is a kind of easy to assembly, the guidance quality height, and stability is strong, can increase work efficiency in engineering truck production and working procedure, and can improve the support fixed structure of telescopic oil cylinder in the working life of telescopic oil cylinder.
Description of drawings
Fig. 1 is the assembly relation between telescopic oil cylinder and telescopic boom, the basic arm;
Fig. 2 is the assembly relation between piston shoes and the supporting frame.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, telescopic boom 1 is enclosed within the basic arm 2, and two earrings of telescopic oil cylinder 3 are hinged on respectively on the bearing on telescopic boom 1 and the basic arm 2, between piston shoes 4 and the supporting frame 5.An end that closes on its piston rod on telescopic oil cylinder 3 has been bolted to connection supporting frame 5, has been bolted to connection piston shoes 4 on supporting frame 5, the inwall sliding contact of piston shoes 4 and telescopic boom 1.
Referring to Fig. 1 and Fig. 2, be fixed with supporting frame 5 owing on telescopic oil cylinder 3, close on an end of its piston rod, on supporting frame 5, be fixed with piston shoes 4, it is unsettled that the inwall sliding contact of piston shoes 4 and telescopic boom 1, supporting frame 5 and piston shoes 4 are supported the telescopic oil cylinder middle part not have, and makes the easy to assembly of telescopic oil cylinder, the guidance quality height, stability is strong, in engineering truck production and working procedure, can increase work efficiency, thus the working life of improving telescopic oil cylinder.
The form of fracture of telescopic boom 1 and basic arm 2 comprises rectangle, triangle or other shape.
Claims (1)
