The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As Fig. 1～shown in Figure 4; mine hoist safety fender guard of the present utility model; comprise and be used for to be pulled through the haul device automatic locking mechanism of haul device 2 pinnings of lifting track 1 limit position more than one group with fall arrest; automatic locking mechanism comprises the lock part and the hanging hook assembly 8 that can fasten mutually; lock part is located on the haul device 2, and hanging hook assembly 8 is installed in and promotes track 1 top.By automatic locking mechanism is set, when haul device 2 was pulled through limit position, hanging hook assembly 8 can hook lock part, prevented that wire cable rupture from causing haul device by gravity to drop fast, causes safety misadventure.
In the present embodiment, haul device automatic locking mechanism is provided with two groups, is that the center is symmetrical arranged with the vertical center line that promotes track 1.Lock part on the haul device 2 is preferably the lock groove of being located on the haul device 2 both sides crossbeams 12 5.Hanging hook assembly 8 comprises hook 13, retracing spring 16 and firm banking 14, and retracing spring 16 and firm banking 14 all are fixed in the top that promotes track 1.Hook 13 is one shaft-like, its end relative with crossbeam 12 is provided with a hook portion, this hook portion and crossbeam 12 relative sides are provided with the guide part 17 of the wedge shape under being tilted to, be convenient to slide into or skid off lock groove 5, the middle part of shaft-like hook 13 is articulated on the firm banking 14 by set pin 15, and can rotate around this its hinge-point, the afterbody support and connection of shaft-like hook 13 are in the top of retracing spring 16, be the both sides that the retracing spring 16 and the hook portion of hook 13 are located at hinge-point, when crossbeam 12 collides hook 13 the time, the guide part 17 of linking up with 13 front sides can make hook 13 around set pin 15 clickwises, this moment, retracing spring 16 was compressed, if crossbeam 12 continues to move to the hook portion of lock groove 5 and hook 13 at once, hook 13 spring 16 that promptly is reset promotes left-hand revolutions and buckles in the lock groove 5, realizes the locking to haul device 2.
In the present embodiment, also comprise two groups of bumper assemblies, two groups of bumper assemblies are that the center is symmetrical arranged with the vertical center line that promotes track 1, each bumper assembly includes crash bar 6 and the bump rubber 7 that cooperatively interacts, crash bar 6 is installed in the front portion of haul device 2, bump rubber 7 is installed in the top that promotes track 1, and crash bar 6 is corresponding with the position of bump rubber 7.When haul device 2 moves to the vertex that promotes track 1, crash bar 6 will strike on the bump rubber 7, can stop or slow down the further motion of haul device 2, prevent that the steel rope 9 of gig from being broken.
When being equiped with the gig work of the utility model safety guard, drive winch cylinder 4 by electrical motor 11 and reductor 10, winch cylinder 4 moves back and forth in promoting track 1 by the steel rope 9 pulling haul devices 2 that are set around on the pulley 3.
When gig work was normal, the stroke of haul device 2 can not arrive the vertex that promotes track 1, and the crash bar 6 on the haul device 2 can not bump against on the bump rubber 7.
When the appearance of top lander do was unusual, haul device 2 may move to the vertex that promotes track 1, and at this moment the crash bar 6 on the haul device 2 will strike on the bump rubber 7; If winch cylinder 4 also continues haul device 2 is up drawn, the crossbeam 12 of haul device 2 both sides will strike hook 13, make hook 13 around set pin 15 rotations, retracing spring 16 is compressed, if crossbeam 12 continues to move to the hook portion position of its lock groove 5 and hook 13 at once, hook 13 spring 16 that can be reset promotes to buckle in the lock groove 5.If at this moment steel rope 9 is broken, haul device 2 is just held by hook 13, can prevent from that haul device 2 by gravitys from falling downwards to cause safety misadventure.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite all should be considered as protection domain of the present utility model.
