Description
Technical field
The present invention relates to gig, refer in particular to a kind of simple and easy gig with unpowered safety device.
Background technology
The mine hoist safety device is dynamic at present; This safety device provides guarantee for the safe operation of gig really; But this covering device investment is bigger, and therefore many enterprises do not have safety device at the simple and easy gig of usefulness at present, makes to produce to can not get safety control; Often because of the steel cable fracture brings bigger economic loss, the life accident takes place in weight person.Use enterprise invar silk fracture of rope to take place and to promote the accident that goods falls from several meters eminences in case and the case through regular meeting; The lighter will promote case and break distortion; And to repair in narrow space at gig also be a very difficult thing; Weight person breaks institute's delivery of cargo thing or causes casualties, and the operator is trembled with fear.
Summary of the invention
The objective of the invention is to improve and innovate, a kind of simple and easy gig with unpowered safety device is provided to the defective that exists in the background technology and problem.
Technical scheme of the present invention is that a kind of steel rope, electric block and hook and wire cable rupture of promoting object of comprising of structure stops the unpowered safety device that promotes the object tenesmus, wherein:
Unpowered safety device comprises corresponding two tracks that are provided with; Correspondence is arranged on the track both sides and is fixed on voussoir, braking voussoir, the track adjusting wheel that promotes on the case; With with hook bonded assembly cross bar; And cross bar top coupling hook, the bottom connects hanging hook through extension spring, and the cross bar two ends connect the braking voussoir of each suspension rod and track both sides respectively through lever;
Described braking voussoir is located between track and the voussoir and moves; And the braking voussoir contacts with the voussoir inclined-plane; The voussoir inclined-plane is wide at the top and narrow at the bottom, the braking voussoir is up-narrow and down-wide, and steel rope or hanging hook fracture braking voussoir stop through the top that extension spring effect upward movement is fastened on voussoir; Described braking voussoir contacts with track friction, and friction moves up to grip track and stops.
Advantage of the present invention and beneficial effect:
The present invention is simple in structure, and is safe and reliable, in real-world operation, repeatedly saves the accident of pulling apart initiation because of steel rope and takes place, simultaneously economical and practical, owing to simple in structurely only need at ordinary times to keep that several hinge-points are hinged to get final product flexibly.
Description of drawings
Fig. 1 is a structural principle scheme drawing of the present invention.
The specific embodiment
Can know by Fig. 1, the present invention includes steel rope 13, the electric block 14 that promotes object and link up with 9 and steel rope 13 fractures stop the unpowered safety device that promotes the objects tenesmus, wherein:
Unpowered safety device comprises corresponding two tracks 1 that are provided with; Correspondence is arranged on track 1 both sides and is fixed on voussoir 4, braking voussoir 5, the track adjusting wheel 3 that promotes on the case 2; With with the hook 9 bonded assembly cross bars 8; And cross bar 8 top coupling hooks 9, the bottom connects hanging hook 12 through extension spring 10, and cross bar 8 two ends connect the braking voussoir 5 of each suspension rod 6 and track 1 both sides respectively through lever 7;
Described braking voussoir 5 is located in motion between track 1 and the voussoir 4; And braking voussoir 5 contacts with voussoir 4 inclined-planes; Voussoir 4 inclined-planes are wide at the top and narrow at the bottom, braking voussoir 5 is up-narrow and down-wide, and braking voussoir 5 stops through the top that extension spring 10 effect upward movements are fastened on voussoir 4 when steel rope 13 fractures or hanging hook 12 fractures; Described braking voussoir 5 and track 1 wipe contact, friction moves up to grip track 1 and stops.
Described each lever 7 of the present invention is provided with fulcrum 11, and the cross bar coupling end is stressed moves downward for lever 7, and mentions lever 7 other end bonded assemblys braking voussoir 5 upward movements through fulcrum 11 simultaneously.Described cross bar 8 two ends connect two groups of levers 7 respectively through hinge.
Structure of the present invention and principle of work:
The similar elevator of gig of the present invention is made up of two tracks 1, lifting case 2 and electric block 14; Wherein promote four track adjusting wheels 3, four voussoirs 4, four fulcrums 11,12, extension springs 10 of hook are installed on the case 2; Extension spring 10 1 ends in succession the hook 12 other ends be pulled on the cross bar 8, the two ends of cross bar 8 are connecting four levers 7 respectively through hinge, the other end of lever 7 is connecting suspension rod 6; Suspension rod 6 links to each other with braking voussoir 5 at last, and the fishhook hook of electric block 14 cross bar 8.
The present invention's fishhook hook of electric block 14 in normal operation the pulling force that cross bar 8 overcomes extension spring 10; Carrying lifting case up-and-down movement through steel rope 13; In case steel rope 13 fractures, cross bar 8 drives lever 7 under the effect of extension spring 10 mentions suspension rod 6 through fulcrum 11, and suspension rod 6 is mentioned braking voussoir 5 again; Voussoir 4 inclined-planes that promote on the case are close on the inclined-plane of the braking voussoir of carrying on this moment 5; Another of braking voussoir 5 faced directly and is close to track 1 and does the friction motion, when this friction during greater than the gravity that promotes case and its cargo four braking voussoirs 5 will clamp two tracks, whole lifting case is still in its cargo in the air.Protected the lifting case to fall and broken distortion, also avoided the loss and the personal casualty of goods from freedom of the air.Only need gig upwards be promoted behind the steel rope that more renews and brake voussoir 5 brake off under the opposite force effect of each mechanism this moment, gig recovers normal operation.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention, engineering staff make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention; The technology contents that the present invention asks for protection all is documented in claims.
