Abstract

The utility model discloses an anti-falling apparatus for a hydraulic flexible shaft guide and the apparatus comprises a movable shaft guide. Movable blocks of the movable shaft guide are provided with blocks; an anti-falling board preventing the movable shaft guide from falling is arranged below the blocks; the anti-falling board matches with the blocks; and the anti-falling board is driven by an externally-arranged oil tank. The anti-falling apparatus for a hydraulic flexible shaft guide is simple in structure and good in design; a mechanical blocking method is employed to prevent the movable shaft guide from falling; the method is firmer than a hydraulic method; the mechanical blocking method enables the whole hydraulic flexible pot system safer and more reliable; and the anti-falling apparatus for a hydraulic flexible shaft guide possesses great practicality, thereby enabling generating great economic and social effects.

Description

A kind of anti-fall device of hydraulically extensible cage guide

Technical field

The utility model relates to the hydraulically extensible cage guide, is specifically related to a kind of anti-fall device 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, 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upwards lifts together, and movable jar 4 is shunk under the effect of wedge mechanism 3, and Moving cage guide 4 is withdrawn under the effect of oil cylinder fixedly in the cage guide like this.After Moving cage guide is regained, by the hydraulic lock on the master cylinder oil cylinder piston lever lock is lived, prevent that Moving cage guide from down falling.Because hydraulic efficiency pressure system exists booster, danger such as card valve etc., Moving cage guide down falls automatically sometimes, analogue all occurs as Pan Beikuang, the Wang Feng Gang Kuang of Huainan Mining Group, has potential safety hazards such as personal casualty, device damage.

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-fall device of hydraulically extensible cage guide,, safety and reliable simple with the realization system.Another purpose of the present utility model provides a kind of hydraulically extensible cage guide that has anti-fall device.

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-fall device of hydraulically extensible cage guide is provided with block at the movable block of Moving cage guide, has with suitable being used for of block at described block and prevents the anti-fall plate that Moving cage guide falls, and described anti-fall plate is by the peripheral hardware hydraulic oil cylinder driving.

Described anti-fall plate links to each other with the piston rod of peripheral hardware oil cylinder, and guide plate play the guiding role to anti-fall plate.

Described peripheral hardware oil cylinder is connected on the fixed support.

A kind of hydraulically extensible cage guide that has anti-fall device comprises Moving cage guide, is provided with block at Moving cage guide, has with suitable being used for of block at described block and prevents the anti-fall plate that Moving cage guide falls, and described anti-fall plate is by the peripheral hardware hydraulic oil cylinder driving.

During the work of the anti-fall device of hydraulically extensible cage guide, in the Moving cage guide retraction fixedly behind the cage guide, by below the guide plate importing block, and the holding position immobilizes anti-fall plate under hydraulic-driven; When Moving cage guide will stretch out, regain anti-fall plate earlier, stretching out Moving cage guide then.

Beneficial effect: the anti-fall device of hydraulically extensible cage guide of the present utility model; simple in structure; reasonable in design; adopt the mode of mechanical stop to guarantee that Moving cage guide does not fall; this mode is more firm 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.

Fig. 2 is the structural representation of anti-fall device;

Fig. 3 is that the AA of Fig. 2 is to view;

Fig. 4 is the cutaway view of anti-fall device.

The specific embodiment

Below in conjunction with concrete accompanying drawing the utility model is described further.

Shown in Fig. 2,3 and 4, the anti-fall device of hydraulically extensible cage guide comprises Moving cage guide 4, movable block 10 at Moving cage guide 4 is provided with block 7, below block 7, be provided with suitable being used for of block 7 prevent that Moving cage guide 4 from falling anti-fall plate 6, this anti-fall plate 6 is driven by peripheral hardware oil cylinder 8, and anti-fall plate 6 links to each other with the piston rod of peripheral hardware oil cylinder 8, and guide plate 9 links to each other with anti-fall plate 6,9 pairs of anti-fall plates 6 of guide plate play the guiding role, and peripheral hardware oil 8 is connected on the fixed support 11.

This anti-fall device is to increase an anti-fall plate 6 that matches and use with block 7 in the Moving cage guide 4 of existing hydraulically extensible cage guide, and anti-fall plate 6 is driven by peripheral hardware oil cylinder 8.During work, when Moving cage guide 4 need be mentioned, 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 Moving cage guide 4 shrinks under the effect of wedge mechanism 3, and withdrawal is fixedly in the cage guide 2 under the effect of oil cylinder, this moment, anti-fall plate 6 was under the driving of peripheral hardware oil cylinder 8, along the guiding of guide plate 9, stretch into the block 7 times on the movable block 10, and after cooperating, block 7 can effectively prevent falling of Moving cage guide 4.When Moving cage guide 4 needs to fall, anti-fall plate 6 is earlier under the driving of peripheral hardware oil cylinder 8, guiding along guide plate 9, block from movable block 10 is extracted out for 7 times, high pressure oil enters 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 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.

A kind of hydraulically extensible cage guide that has anti-fall device comprises Moving cage guide 4, is provided with block 7 at Moving cage guide 4, has with block 7 suitable being used at block 7 and prevents the anti-fall plate 6 that Moving cage guide falls, and anti-fall plate 6 is by the peripheral hardware hydraulic oil cylinder driving.In the hydraulically extensible cage guide of anti-fall device is housed, adopt the mode of mechanical stop to guarantee that Moving cage guide does not fall, this mode is more firm than the mode of hydraulic pressure, makes that whole hydraulically extensible can system is safer and reliable, has good practicability.
