Summary of the invention
The objective of the invention is provides a kind of Simple-structure hoisting machine with power-free safety device for the defective that exists in background technology and problem improvement and bring new ideas in addition.
Technical scheme of the present invention is that structure a kind ofly comprises steel rope, electric block and the hook that promotes object, and wire cable rupture stops and promote the power-free safety device that object drops, wherein:
Power-free safety device comprises corresponding two tracks that arrange, correspondence is arranged on track both sides and is fixed on voussoir, braking voussoir, track adjusting wheel on lift tank, with the cross bar that is connected with hook, and cross bar top coupling hook, the bottom connects hanging hook by extension spring, and cross bar two ends connect respectively the braking voussoir of each suspension rod and track both sides by lever;
Described braking voussoir is located between track and 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 by 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 occurs, simultaneously economical and practical, only needs at ordinary times to keep due to simple in structure that several hinge-points are hinged to be got final product flexibly.
Description of drawings
Fig. 1 is structural principle schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes steel rope 13, the electric block 14 that promotes object and link up with 9, and the power-free safety device of steel rope 13 fracture prevention lifting object tenesmus, wherein:
Power-free safety device comprises corresponding two tracks 1 that arrange, correspondence is arranged on track 1 both sides and is fixed on voussoir 4, braking voussoir 5, track adjusting wheel 3 on lift tank 2, with with the hook 9 cross bars that are connected 8, and cross bar 8 top coupling hooks 9, the bottom connects hanging hooks 12 by extension spring 10, and cross bar 8 two ends connect respectively the braking voussoir 5 of each suspension rod 6 and track 1 both sides by lever 7;
Described braking voussoir 5 is located in motion between track 1 and 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 by the top that extension spring 10 effect upward movements are fastened on voussoir 4 when steel rope 13 fractures or hanging hook 12 fracture; 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 by fulcrum 11 braking voussoir 5 upward movements that lever 7 other ends connect simultaneously.Described cross bar 8 two ends connect respectively two groups of levers 7 by hinge.
Structure of the present invention and principle of work:
The similar elevator of gig of the present invention is comprised of two tracks 1, lift tank 2 and electric block 14, four track adjusting wheels 3, four voussoirs 4, four fulcrums 11,12, extension springs 10 of a hook wherein are installed on lift tank 2, extension spring 10 1 ends in succession the hook 12 other ends be pulled on cross bar 8, the two ends of cross bar 8 are connecting respectively four levers 7 by hinge, the other end of lever 7 is connecting suspension rod 6, suspension rod 6 is connected 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 the lift tank up-and-down movement by steel rope 13, in case steel rope 13 fractures, cross bar 8 drives lever 7 and by fulcrum 11, suspension rod 6 is mentioned under the effect of extension spring 10, suspension rod 6 is mentioned braking voussoir 5 again, voussoir 4 inclined-planes on lift tank are close on the inclined-plane of the braking voussoir 5 of carrying on this moment, another of braking voussoir 5 faced directly and is close to track 1 do friction motion, when this friction during greater than the gravity of lift tank and its cargo four braking voussoirs 5 will clamp two tracks, whole lift tank and its cargo are still in the air.Protect lift tank to fall from freedom of the air and broken distortion, also avoided loss and the personal casualty of goods.Only need after the steel rope that more renews gig is upwards promoted 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 is only the description that the preferred embodiment 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; various modification and improvement that in this area, engineering staff make technical scheme of the present invention; 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.
