Abstract
The utility model discloses a steering locked oil cylinder, which comprises an air cylinder body and a hydraulic cylinder body, wherein the air cylinder body is provided with an air inlet oil port; the hydraulic cylinder body is provided with two oil ports; the right end of a solid piston rod of the hydraulic cylinder body is provided with a U-shaped groove; steel ball mounting holes are distributed on the excircle at the left end of a hollow piston rod in the air cylinder body; an air cylinder piston and a sliding sleeve are arranged outside the hollow piston rod; and the sliding sleeve is matched with a spring. By adopting a structure of connecting the hydraulic cylinder with the air cylinder in series, the hydraulic cylinder body is connected with the air cylinder body through a flange and bolts, the utility model finishes the locking and the unlocking of the oil cylinder by the solid piston rod of the hydraulic oil cylinder, the hollow piston rod of the air cylinder, the sliding sleeve, steel balls, the spring and other components, thereby realizing the locking and unlocking functions for the steering of an all-ground crane. The device has simple structure and reliable performance; and since all the solid piston rod of the hydraulic oil cylinder, the hollow piston rod of the air cylinder and an inner hole of the sliding sleeve have enough hardness, favorable wear resistance and impact resistance, the service life of the steering locked oil cylinder can be prolonged.
Description
Technical field
It is used that the utility model relates to steering equipment, has locked and oil cylinder unlocking function.
Background technique
Steering lock dead oil cylinder is that full ground hoist turns to a kind of locking mechanism of fastening, be mainly used at present in the new model of full ground hoist, because the locking function of steering lock dead oil cylinder lost efficacy, it is poor a lot of to cause the back axle of full ground hoist and propons to turn to, cause the unusual of tire, cause tire wear serious, very easily cause a serious accident.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, reliable performance, can be good at satisfying the frequent locked and unlocking function that full ground hoist turns to, and the steering lock dead oil cylinder of long service life.
The purpose of this utility model is achieved in that a kind of steering lock dead oil cylinder, comprise cylinder block and hydraulic cylinder, connect by oil hydraulic cylinder flange, cylinder flange and bolt between cylinder block and the hydraulic cylinder, cylinder block is provided with air and oil, hydraulic cylinder is provided with two hydraulic fluid ports, the solid piston bar right-hand member of hydraulic cylinder is processed with U-groove bevel, be evenly equipped with the steel ball mounting hole on the box type piston bar left end cylindrical in the cylinder block, steel ball places in the steel ball mounting hole, the box type piston bar is provided with cylinder piston and sliding sleeve outward, and sliding sleeve matches with spring.The box type piston bar is provided with meta and detects hydraulic fluid port.
The steering lock dead oil cylinder that the utility model provides, the structure that adopts oil hydraulic cylinder and cylinder to contact mutually, oil hydraulic cylinder links to each other with bolt by flange with cylinder two cylinder bodies, solid piston bar and the parts such as box type piston bar, sliding sleeve, steel ball and spring of the cylinder locked and release of finishing oil cylinder of this device by hydraulic jack is from the frequent locked and unlocking function of realizing that full ground hoist turns to.This apparatus structure is simple, and reliable performance is because the solid piston bar of hydraulic jack and box type piston bar, the sliding sleeve endoporus of cylinder all have enough hardness and good wear resistance, impact resistance, the working life of having improved steering lock dead oil cylinder greatly.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural drawing that steering lock dead oil cylinder is in locking state.
Fig. 2 is a B-B sectional view among Fig. 1.
Fig. 3 is a D-D sectional view among Fig. 1.
Fig. 4 is the structural drawing that steering lock dead oil cylinder is in released state.
Fig. 5 is that steering lock dead oil cylinder is under the released state, the structural drawing when solid piston moves to the neutral position of hydraulic jack.
Embodiment
As shown in Figure 1, the utility model is mainly by solid piston bar 1, oil hydraulic cylinder guide sleeve 2, hydraulic cylinder 3, solid piston 4, cylinder guidance cover 5, spring 6, cylinder block 7, steel ball 8, back-up ring 9, sliding sleeve 10, cylinder piston 11, box type piston bar 12, bolt 13 compositions such as grade, pass through oil hydraulic cylinder flange 14 between cylinder block 7 and the hydraulic cylinder 3, cylinder flange 15 and bolt 13 connect, cylinder block 7 is provided with air and oil 18, hydraulic cylinder 3 is provided with two hydraulic fluid ports 19,19 ', solid piston bar 1 right-hand member of hydraulic cylinder 3 is processed with U-groove bevel 16, be evenly equipped with steel ball mounting hole 17 on the box type piston bar 12 left end cylindricals in the cylinder block 7, steel ball 8 places in the steel ball mounting hole 17, be provided with cylinder piston 11 and sliding sleeve 10 outside the box type piston bar 12, sliding sleeve 10 matches with spring 6.Box type piston bar 12 is provided with meta and detects hydraulic fluid port 19.
Working principle of the present utility model is: oil cylinder is in locking state and sees accompanying drawing 1, the air pressure of 0.8MPa constantly is provided to the air and oil 18 of cylinder block 7, cylinder piston 11 is to left movement in the promotion cylinder, drive sliding sleeve 10 and also be moved to the left pressure spring 6,8 releases of 6X ￠ 15 steel balls, at this moment, the oil pressure of 16MPa is provided for respectively oil hydraulic cylinder two hydraulic fluid ports 20 and 20 ', can drives solid piston bar 1 and move leftwards and rightwards respectively, 6X ￠ 15 steel balls 8 upwards spring in the sliding sleeve 10 naturally.Thereby realize the unlocking function of steering lock dead oil cylinder, the state during release is seen accompanying drawing 2.
Otherwise, when this oil cylinder is in released state, when the solid piston 4 of hydraulic cylinder 3 moves to the neutral position of hydraulic cylinder 3, as shown in Figure 3, the meta of putting into measurer detects hydraulic fluid port 19, the U-groove bevel 16 that can record solid piston bar 1 right-hand member just in time is on the steel ball mounting hole 17 that 6 ￠, 15 steel balls 8 are housed on the box type piston bar 12, and 6 ￠ 15 steel balls 8 can accurately drop in the U-groove bevel 16.At this moment, stop air and oil 18 air feed to cylinder block 7, sliding sleeve 10 is by the elastic reset of spring 6,6 ￠, 15 steel balls 8 are locked, solid piston bar 1 links into an integrated entity with the steel ball 8 of box type piston bar 12 by 6 ￠ 15, promptly play the effect of linkage mechanism, thereby realize the locking function of steering lock dead oil cylinder.
