Abstract
The utility model discloses an anti-folding apparatus of hydraulic shaft guide with flexibility and the apparatus comprises a limited block clutched between two movable blocks of a movable shaft guide and the limited block prevents the two movable blocks from converging after a distraction. The limited block is driven by an outer oil tank. The anti-folding apparatus is simple in structure and good in design; a mechanical chucking method is employed to ensure an expansion width of the movable shaft guide which is the same as a fixed shaft guide; the method is more reliable and firmer than a hydraulic method; by the method, the whole hydraulic flexible pot is safer and more reliable, thereby enabling the pot with good practicality and producing great economic and social effects.
Description
Technical field
The utility model relates to the hydraulically extensible cage guide, is specifically related to a kind of anti-device that closes up of hydraulically extensible cage guide.
Background technology
Flexible cage guide is a kind of shaft equipment for the multilevel mine shaft hoist system of end cage guide, existing flexible cage guide (CN101531314B), as shown in Figure 1, its groundwork principle is: when high pressure oil enters master cylinder 1 epicoele, piston rod drives Moving cage guide 4, wedge mechanism 3 etc. and stretches out downwards together.When the bullet of Moving cage guide 4 front ends was inserted into down cone tank on the fixing cage guide 5, Moving cage guide 4 launched under the effect of wedge mechanism 3, and its developed width is with last fixedly cage guide 2 and fixedly cage guide 5 is identical down.When high pressure oil enters master cylinder 1 cavity of resorption, piston rod drives Moving cage guide 4, wedge mechanism 3 etc. and upwards lifts together, and movable jar, 4 shrink under the effect of wedge mechanism 3, and Moving cage guide 4 shrinks under the effect of oil cylinder fixedly in the cage guide like this.Stretch out at Moving cage guide, in conjunction with and be deployed into width identical with fixing cage guide after, the maintenance of its expansion cross dimensions of Moving cage guide by hydraulic efficiency pressure system pressurize finish.Because there are danger such as booster, card valve in hydraulic efficiency pressure system, after master cylinder epicoele dwell pressure was lower than setting pressure, Moving cage guide will shrink under external force, influenced lifting container to pass through, and had major safety risks; Hydraulic pressure, electric system complexity in addition, the cost height.
The utility model content
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of anti-device that closes up of hydraulically extensible cage guide,, safety and reliable simple with the realization system.Another purpose of the present utility model provides a kind of anti-hydraulically extensible cage guide that closes up device that has.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of anti-device that closes up of hydraulically extensible cage guide comprises that described limiting stopper is driven by the peripheral hardware actuating device for the limiting stopper that Moving cage guide shrinks again that prevents that inserts Moving cage guide after strutting.
Described limiting stopper links to each other with the expansion link of peripheral hardware oil cylinder, is connected with guide plate at expansion link.Guide plate play the guiding role to limiting stopper.
Described peripheral hardware oil cylinder is connected on the fixed support.
A kind of hydraulically extensible cage guide of preventing closing up device that has is provided with the limiting stopper that shrinks again after Moving cage guide from strutting be used to preventing at Moving cage guide, and described limiting stopper is driven by the peripheral hardware actuating device.
When hydraulically extensible cage guide anti-closed up device work, with after fixedly cage guide touches mutually and launches down, limiting stopper was imported between two movable blocks by guide plate under hydraulic-driven at Moving cage guide, tightened and the holding position immobilizes; When Moving cage guide will shrink, regain limiting stopper earlier, then at the contraction movement cage guide.
Beneficial effect: the anti-device that closes up of hydraulically extensible cage guide of the present utility model; simple in structure; reasonable in design; the mode that adopts machinery to tighten guarantees the developed width of Moving cage guide and fixedly cage guide is identical; this mode is more solid and reliable than the mode of hydraulic pressure; make that whole hydraulically extensible can system is safer and reliable, have good practicability, can produce good economic benefits and social effect.
Description of drawings
Fig. 1 is the structural representation of existing hydraulically extensible cage guide;
Fig. 2 is the anti-structural representation that closes up device.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in Figure 2, the anti-device that closes up of hydraulically extensible cage guide comprises that limiting stopper 6 is driven by peripheral hardware oil cylinder 8 for preventing the limiting stopper 6 that two movable blocks 10 shrink between two movable blocks 10 that insert Moving cage guide 4 when strutting.Limiting stopper 6 links to each other with the expansion link of peripheral hardware oil cylinder 8, is connected with guide plate 7 at expansion link.Peripheral hardware oil cylinder 8 is connected on the fixed support 9.
Should anti-close up device is to increase a limiting stopper 6 that matches and use with two movable blocks 10 in the Moving cage guide 4 of existing hydraulically extensible cage guide (CN101531314B), during work, high pressure oil enters master cylinder 1 epicoele, piston rod drives Moving cage guide 4, wedge mechanism 3 etc. and stretches out downwards together, when the bullet of movable jar of 4 front ends is inserted into down cone tank on the fixing cage guide 5, Moving cage guide 4 launches under the effect of wedge mechanism 3, and its developed width is with fixedly cage guide is identical.Limiting stopper 6 inserts under the driving of peripheral hardware oil cylinder 8 in two movable blocks 10 of Moving cage guide 4 then, and it is constant to guarantee that two movable blocks 10 keep it to launch cross dimensions under external force.When Moving cage guide 4 need be mentioned, limiting stopper 6 was extracted out from two movable blocks 10 under the driving of peripheral hardware oil cylinder 8, and high pressure oil enters master cylinder 1 cavity of resorption, and piston rod drives Moving cage guide 4, wedge mechanism 3 etc. and upwards lifts together.Moving cage guide 4 shrinks under the effect of wedge mechanism 3, and Moving cage guide 4 shrinks under the effect of oil cylinder fixedly in the cage guide 2 like this.
A kind ofly have an anti-hydraulically extensible cage guide that closes up device, be provided with the limiting stopper 6 that shrinks again the time after Moving cage guide from strutting be used to preventing at Moving cage guide, limiting stopper 6 is driven by the peripheral hardware actuating device.Anti-closing up in the hydraulically extensible cage guide of device is being housed, and the mode that adopts machinery to tighten guarantees the developed width of Moving cage guide 4 and fixedly cage guide is identical, and this mode is more solid and reliable than the mode of hydraulic pressure, makes that whole hydraulically extensible can system is safer and reliable.
