Abstract
The utility model relates to a bridge crane guardrail. Brackets are manufactured at the tail ends of a track of a trolley of a bridge crane; pulleys are mounted on the brackets; one end of a steel rope long enough is formed on a trolley body of the crane; and the other end of the steel rope passes through the pulleys of one bracket at the end part of the track, then the trolley body and to the pulleys of the bracket at the other end of the track, returns to the trolley body and is fixed on the trolley body. The guardrail is a dynamic device guardrail, can have a safety protection effect, is not limited by a field, occupies very small space, can be dynamically adjusted, can be adjusted according to site requirements, is convenient to mount and dismount, and can ensure normal operation of equipment.
Description
Affiliated technical field
This utility model belongs to the hoisting crane affiliated facility, particularly the crane in bridge type guardrail.
Technical background
Known weight-lifting equipment safety barrier all is fixed, be to be welded by one by one pipe or angle steel, its safety precaution effect is no doubt very strong, but, be subjected to place and space constraint, the safety barrier of the type can't be installed on the girder of overhead traveling crane equipment is walked on stage, and walking on stage with regard to the girder that has caused overhead traveling crane equipment does not like this have safety barrier, has major safety risks.
The utility model content
Be subjected to place and space constraint and defective that can not dynamic adjustments in order to overcome the fixation type safety guardrail, the utility model provides a kind of crane in bridge type guardrail, it is a cover dynamic apparatus guardrail, not only can play the safety precaution effect, not limited by the place, it is minimum to take up room, and can dynamic adjustments, easy accessibility can be regulated guardrail according to on-the-spot needs.
The technical scheme that its technical matters that solves the utility model adopts is: the crane in bridge type guardrail, track end at the dolly of crane in bridge type is made a support, adorn pulley on the support, with a sufficiently long steel cable, an end is fixed on the little car body of hoisting crane, and the other end passes the pulley of a support of rail end, pass little car body again, again to the support pulley of the track other end, and then get back to little car body, be fixed on the little car body.So just formed twice steel cable guardrail, and this guardrail can move along with the motion of dolly, can normally not move dolly and produce any influence,
Effect of the present utility model is: it is a cover dynamic apparatus guardrail, not only can play the safety precaution effect, not limited by the place, it is minimum to take up room, and can dynamic adjustments, can regulate easy accessibility to guardrail according to on-the-spot needs, the normal operation of equipment can be guaranteed, also the safety precaution effect can be played.
Description of drawings
Accompanying drawing is crane in bridge type guard bar structure scheme drawing.
Among the figure: 1-pulley bracket, 2-steel cable, 3-dolly, 4-pulley, 5-pipe, 6-trolley track, 7-girder platform.
The specific embodiment
As shown in drawings, the crane in bridge type guardrail is installed in 8 pulleys on pulley bracket 1 and the dolly 3 earlier, two pulley brackets 1 is separately fixed on the girder platform 7 of inboard, trolley track 6 two ends again.Need reserve the position earlier before fixing, pulley bracket 1 can not influence dolly 3 and normally move, and then steel cable 2 one ends of Φ 12 are fixed on the A of dolly 3, the other end is fixed on the other end B of dolly 2 after passing 8 pulleys again, fixedly should be earlier with its tension before the steel cable 2, to guarantee that simultaneously A point and B point are roughly on same horizon, with Φ 25 pipes it is blocked between the clearance C point that is left between the dolly 3 and the D point, so just can guarantee when dolly 3 when trolley track 6 moves, steel cable 2 is in tensioning state all the time, and then plays the effect of guard rail.
Claims (1)
