Abstract
Disclosed is an anti-falling device for the counter weight of the lifting conveyor, which comprises a breaking mechanism and a starter of the breaking mechanism that are fitted on the side frame of the counter and the bridging beam, and a vertical braking rail fixed on the rack of lifting conveyor. The upper end of the boom of braking starter connects to the drive chain, the lower end links to an elastic connection board and steel wire and the upper end of wheel carrier of a pair of braking wheel that placed between the steering planes of the splayed brake base. The lower part of the braking wheel carrier connects to the brake base master by the extension spring. At the same time, a pair of braking wheels mentioned is placed at the both sides of the vertical braking orbit. The utility model is quick and reliable in movement, simple in structure, lower in manufacture cost. It is especially suitable for the counter weight of the reciprocating lifting conveyor in preventing the falling of the counter weight when the drive chain breaks accidentally.
Description
Technical field
The utility model belongs to the safety device of gig, particularly relates to reciprocal gig and be used for a kind of device of keeping clump weight not fall under its driving chain crack conditions.
Background technology
Back and forth gig is the heavy load transfer device that is used for the vertical transport goods, its loading platform generally all is hung on an end of driving chain, the other end of driving chain then is hung with clump weight, and the effect of this clump weight is the gravity of balance loading platform, to alleviate the load of drive motor.Because the weight of clump weight is all heavier, therefore prevent that clump weight from falling in the work, guarantee that safety in operation is very important.At present, relevant anti-dropping safety device has multiple structures such as electromagnetic type, electromechanical, but most complex structure, the cost height.
Summary of the invention
The purpose of this utility model, it is simple and flexible movements are reliable to provide a kind of structure, and manufacturing cost is lower, is particularly useful for the anti-dropping safety device of reciprocal gig clump weight.
Technical solution of the present utility model is: it is by stop mechanism, brake actuating mechanism and braking rail are formed, its stop mechanism has the drg seat that is installed on the clump weight frame, offer a chamber on the drg seat, the internal face top, both sides in door chamber is provided with and is mutually splay braking spigot surface, the a pair of brake wheel that is installed on the braking wheel carrier is positioned at the door chamber of drg seat, be symmetrically located at the both sides that are fixed on the vertical braking rail on the gig frame simultaneously, the bottom of braking wheel carrier is connected by the bottom surface of extension spring with the drg seat, and its top then is connected with the lower end of pipe link; Brake actuating mechanism has the suspension rod that the upper end is connected with driving chain, the suspension rod lower ends downward is passed the clump weight cruciform bracing and is connected with connecting panel, the startup spring is installed on the boom sections between connecting panel and the crossbeam, and connecting panel is connected with the upper end of braking wheel carrier pipe link by steel rope and pulley simultaneously.
During the gig normal operation, clump weight is hung on the driving chain, and the compression of suspension rod pull-up connecting panel starts spring, and the tension of braking wheel carrier tension spring this moment is in the middle part in drg seat door chamber, and brake wheel is in no restrained condition.In case the driving chain fracture takes place, the suspension rod of brake actuating mechanism promptly loses pulling force, originally hung the startup spring that tension and compression are contracted by suspension rod and connecting panel, release spring is tried hard to recommend the plate that is dynamically connected and is moved downward the pulling steel rope at this moment, because the spring force that starts spring is far longer than the spring force of extension spring, the braking wheel carrier just is pulled up, thereby brake wheel is stuck between the braking spigot surface and vertical braking rail of drg seat, because it is big little under the spacing between braking spigot surface and the braking rail, under the ballasted weight effect, brake wheel is blocked tighter and tighter, thereby avoids clump weight to fall reliably.
The utility model is simple in structure, reliable, flexible movements, and manufacturing cost is lower.
