Description

Eccentric wheel type falling proof device
Technical field
The utility model relates to a kind of falling proof device, specifically eccentric wheel type falling proof device.
Background technology
Current electric block lifting means is widely used in industry-by-industry; especially the application of fixing type electric cucurbit; generally be furnished with in fixing type electric cucurbit elevator system and promote track and cage; but electric block is without rope broken protector; hoisting wirerope is once fracture; lifting thing can directly fall to ground, and likely cause serious safety misadventure or economic loss, system exists potential safety hazard.At present, although elevator industry has falling proof device, complex structure, cost be high, need special track with the use of, so its to be not suitable for frequency of utilization not high, a loading is not manned, the operating mode that installing space is limited.
Utility model content
The purpose of this utility model is to provide eccentric wheel type falling proof device; this falling proof device is by the friction of eccentric wheel and track; can will hang thing when hoisting wirerope ruptures fixing in orbit, and prevent lifting thing from falling, while eliminating safe hidden trouble, protection lifting thing is not impaired.
The technical scheme in the invention for solving the technical problem is: eccentric wheel type falling proof device, its structure comprises cage, track and the arm of force, one end of described cage is dynamically connected by track adjusting wheel and track sliding, the roof of cage is provided with the arm of force, described arm of force one end and cage roof are by the first pinned connection, the arm of force other end is provided with the hanger with electric gourd hook hook, the side of described cage roof track is provided with fall arrest parts, described fall arrest parts comprise eccentric wheel, connecting lever and stay cord, described connecting lever and eccentric wheel are by the second pinned connection, bearing pin between eccentric wheel and connecting lever is provided with torque spring, described eccentric wheel is connected with cage top arm by support.
Further, the stay cord one end in described fall arrest parts is connected with the arm of force, and the other end is connected with the lower end of connecting lever.
Further, described eccentric front side is provided with the first support, eccentric rear side is provided with the second support, described first support is connected with cage with the bottom of the second support, the top of the first support and the second support is respectively equipped with through hole, and described second bearing pin is successively through the through hole of connecting lever, the through hole of the first cantilever tip, eccentric wheel and the second cantilever tip; Described torque spring is arranged on the second bearing pin between the first support and connecting lever.
Further, described torque spring drives connecting lever and eccentric wheel to rotate, eccentric wheel and orbit sidewall friction.
The beneficial effects of the utility model are:
(1) this falling proof device structure is simple, reliably compact, and eccentric wheel is directly installed on cage top by support, and installing space is little, equipment cost is low.
(3) this device can prevent lifting thing from falling impaired, eliminates safe hidden trouble.Cage passes through Bracket setting eccentric wheel, carried out the rotation of control eccentric by stay cord and connecting lever, after the hoisting wirerope fracture of electric block, stay cord loses pulling force, connecting lever rotates under the drive of torque spring, the rotating band movable eccentric wheel of connecting lever rotates, make eccentric wheel directly with orbit sidewall friction, can use without the need to dedicated track cooperation, until during being equal in weight of friction force and lifting thing, eccentric wheel stops operating, and lifting thing stops falling, and prevents lifting thing impaired.

Detailed description of the invention
With reference to Figure of description, eccentric wheel type falling proof device of the present utility model is described in detail below.
As Fig. 1, shown in Fig. 3, eccentric wheel type falling proof device of the present utility model, its structure comprises cage 3, track 1 and the arm of force 4, one end of described cage 3 is by track adjusting wheel 2 and track 1 sliding block joint, the roof of cage 3 is provided with the arm of force 4, the described arm of force 4 one end is connected by the first bearing pin 8 with cage 3 roof, the arm of force 4 other end is provided with the hanger with electric gourd hook hook, the side of described cage 3 roof track is provided with fall arrest parts, described fall arrest parts comprise eccentric wheel 6, connecting lever 7 and stay cord 5, described connecting lever 7 is connected by the second bearing pin 13 with eccentric wheel 6, bearing pin between eccentric wheel 6 and connecting lever 7 is provided with torque spring 9, described eccentric wheel 6 is connected with cage 3 top arm by support.Stay cord 5 one end in described fall arrest parts is connected with the arm of force 4, and the other end is connected with the lower end of connecting lever 7.
The front side of described eccentric wheel 6 is provided with the first support 11, the rear side of eccentric wheel 6 is provided with the second support 12, described first support 11 is connected with cage 3 with the bottom of the second support 12, the top of the first support 11 and the second support 12 is respectively equipped with through hole, and described second bearing pin 13 is successively through the through hole on the through hole on connecting lever 7, first support 11 top, eccentric wheel 6 and the second support 12 top; Described torque spring 9 is arranged on the second bearing pin 13 between the first support 11 and connecting lever 7.
As shown in Figure 2, to stay cord one pulling force upwards, stay cord drives connecting lever to rotate, and eccentric wheel is away from track, and cage can move up and down; The pulling force of stay cord disappears, and torque spring drives connecting lever and eccentric wheel to rotate backward, eccentric wheel and orbit sidewall contact friction.
During use, the hook arm of force top hanger lifting of electric block, the suspension hook of electric block is to arm of force generation pulling force vertically upward, because the arm of force 4 is horizontal by 70-80 ° of angle, so the arm of force 4 can produce pulling force component to stay cord 5, pulling force is passed to connecting lever 7 by stay cord 5 makes connecting lever 7 rotate, connecting lever 7 rotates the moment of torsion needing to overcome torque spring 9 and produce, when the moment of torsion that torque spring 9 produces equal stay cord 5 transmit the moment of torsion of pulling force component to connecting lever 7 time, mechanism is in equilibrium of forces point, now eccentric wheel 6 is followed connecting lever 7 and is turned to the not contact position with track 1, thus ensure that cage 3 can freely move up and down.After the hoisting wirerope of electric block disconnects, the suspension hook of electric block disappears to the pulling force that the arm of force 4 produces vertically upward, thus the pulling force that the arm of force 4 pairs of stay cords 5 produce disappears, the equilibrium of torques power produced with torque spring 9 disappears, the moment of torsion that torque spring 9 produces makes eccentric wheel 6 rotate backward, eccentric wheel 6 rotates rear and track 1 contact friction, the pressure produced between eccentric wheel 6 and track 1 increases with the rotation of eccentric wheel 6, thus the friction force between eccentric wheel 6 and track 1 increases, until being equal in weight of friction force and lifting thing, now eccentric wheel 6 stops operating, lifting thing stops falling, coordinate can use without the need to dedicated track.
The above, just explain through diagrams principles more of the present utility model, this specification sheets is not the utility model to be confined in shown described concrete structure and Applicable scope, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
Except technical characteristic described in specification sheets, all the other technical characteristics are those skilled in the art's known technology.
