Abstract
The invention discloses an anti-folding device of a hydraulic telescopic cage guide, which comprises a limit block blocked between two moveable blocks of a moveable cage guide to prevent the two moveable blocks from being retracted after being expanded, wherein the limit block is driven by an external oil cylinder. The anti-folding device is simple in structure and reasonable in design, the expansion width of the moveable cage guide is enabled to be the same as that of a cage guide channel by a mechanical clamping way which is more firm and reliable than a hydraulic way, so that the telescopic kettle system is more safe and reliable on the whole, therefore, the anti-folding device has good practicability and is capable of bringing good economic benefits and social effects.
Description
Technical field
The present invention relates to the hydraulically extensible cage guide, be 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 that is used for holding the multilevel mine shaft hoist system of cage guide; Existing flexible cage guide (CN101531314B); As shown in Figure 1; Its groundwork principle is: when high pressure oil entering 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 the 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 gets into 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 contractions under the effect of wedge mechanism 3 are on Moving cage guide 4 shrinks under the effect of oil cylinder so fixedly in the cage guide.Stretch out, combine at Moving cage guide and be deployed into width identical with fixing cage guide after, its maintenance that launches cross dimensions of Moving cage guide by hydraulic efficiency pressure system pressurize accomplish.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 are complicated in addition, and cost is high.
Summary of the invention
Goal of the invention: to the deficiency that exists in the prior art, the purpose of this invention is to provide a kind of anti-device that closes up of hydraulically extensible cage guide,, safety and reliable simple with the realization system.Another object of the present invention 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 scheme that the present invention adopts is following:
A kind of anti-device that closes up of hydraulically extensible cage guide comprises the limiting stopper that Moving cage guide shrinks again that prevents that is used to insert Moving cage guide after strutting, described limiting stopper is driven by the peripheral hardware actuating device.
Described limiting stopper links to each other with the expansion link of peripheral hardware oil cylinder, on expansion link, is connected with guide plate.Guide plate play the guiding role to limiting stopper.
Described peripheral hardware oil cylinder is connected on the fixed support.
A kind ofly have an anti-hydraulically extensible cage guide that closes up device, be used to prevent the limiting stopper that shrinks again after Moving cage guide is strutting being provided with on the Moving cage guide, 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 invention; 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 present invention is done further explanation.
As shown in Figure 2, the anti-device that closes up of hydraulically extensible cage guide comprises between two movable blocks 10 that are used to insert Moving cage guide 4 preventing the limiting stopper 6 that two movable blocks 10 shrink that when strutting limiting stopper 6 is driven by peripheral hardware oil cylinder 8.Limiting stopper 6 links to each other with the expansion link of peripheral hardware oil cylinder 8, on expansion link, is connected with guide plate 7.Peripheral hardware oil cylinder 8 is connected on the fixed support 9.
Should anti-close up device is in the Moving cage guide 4 of existing hydraulically extensible cage guide (CN101531314B), to increase a limiting stopper 6 that matches and use with two movable blocks 10; During work; High pressure oil gets into master cylinder 1 epicoele, and piston rod drives Moving cage guide 4, wedge mechanism 3 etc. and stretches out downwards together, when the bullet of movable jar 4 front ends is inserted into down the 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 gets into 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, on Moving cage guide 4 shrinks under the effect of oil cylinder so fixedly in the cage guide 2.
A kind ofly have an anti-hydraulically extensible cage guide that closes up device, be used to prevent the limiting stopper 6 that shrinks again the time after Moving cage guide is strutting being provided with on the 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.
