Abstract

The invention discloses a falling protection device for a hydraulically telescopic cage guide, which comprises a movable cage guide. A stopper is arranged on a movable block of the movable cage guide, and a falling protection plate for preventing the movable cage guide from falling is arranged below the stopper, matched with the stopper and driven by an external cylinder. The falling protection device is simple in structure and reasonable in design, and the movable cage guide is prevented from falling by a mechanical stopping method which is more reliable than a hydraulic method, so that a whole hydraulically telescopic cage system is safer and more reliable, has excellent practicability and can achieve excellent economic benefits and social effects.

Description

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

Technical field

The present invention relates to the hydraulically extensible cage guide, be 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 that is used for holding the multilevel mine shaft hoist system of cage guide; Existing flexible cage guide; 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lifts together, and movable jar 4 contraction under the effect of wedge mechanism 3 is on Moving cage guide 4 is withdrawn under the effect of oil cylinder so fixedly in the cage guide.After Moving cage guide is regained, lean on the hydraulic lock on the master cylinder that the 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 like Pan Beikuang, the Wang Feng Gang Kuang of Huainan Mining Group, has potential safety hazards such as personal casualty, device damage.

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-fall device of hydraulically extensible cage guide,, safety and reliable simple with the realization system.Another object of the present invention 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 scheme that the present invention adopts is following:

A kind of anti-fall device of hydraulically extensible cage guide is provided with block on the movable block of Moving cage guide, have with suitable being used to of block at described block and prevent 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, on Moving cage guide, is provided with block, has with suitable being used to 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 invention; 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 present invention is done further explanation.

Like Fig. 2, shown in 3 and 4, the anti-fall device of hydraulically extensible cage guide comprises Moving cage guide 4, on the movable block 10 of Moving cage guide 4, is provided with block 7; Below block 7, be provided with block 7 suitable being used to 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 in the Moving cage guide 4 of existing hydraulically extensible cage guide, to increase an anti-fall plate 6 that matches and use with block 7, 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 got into 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, under the effect of oil cylinder, withdrawing fixedly in the cage guide 2; 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 needed to fall, anti-fall plate 6 was earlier under the driving of peripheral hardware oil cylinder 8, along the guiding of guide plate 9; Block from movable block 10 is extracted out for 7 times; 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.

A kind of hydraulically extensible cage guide that has anti-fall device comprises Moving cage guide 4, on Moving cage guide 4, is provided with block 7, 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.
