Abstract
The utility model relates to a safe falling protector for a gantry crane in process of climbing up and down a straight ladder. The safe falling protector comprises a falling protector, wherein the upper end of the falling protector is fixed on the straight ladder through a hook; a differential mechanism is arranged inside the falling protector and connected with a steel wire rope; a safety buckle is additionally arranged at the lower end of the falling protector and connected with a hauling cable. The safe falling protector has the beneficial effects that the falling protector, upper and lower falling protector mounting buckles and a falling protection traction cable are combined, and meanwhile, the differential mechanism is additionally arranged at the inside of the falling protector, so that the safety of a person climbing up and down the straight ladder can be improved, the safety buckle of the falling protector is pulled down through the rope and connected with a special belt on the person when the person climbs up and down the straight ladder, and the safety buckle is loosened after the person climbs up the straight ladder; if an accident is generated in the climbing process, the wire rope of the falling protector is automatically taken in to prevent the person from falling down when the differential mechanism of the falling protector detects that the speed is too high. Thus, an accident can be effectively prevented.
Description
Technical field
The utility model relates to straddle truck technology, relates in particular to the upper and lower vertical ladder safety anti-falling device of a kind of straddle truck.
Background technology
Portal crane is the one distortion of bridge crane, is mainly used in the handling operation of outdoor goods yard, stock ground goods, bulk goods.Its metal construction, as door-shaped frame, is installed two legs under support main beam, can directly on the track on ground, walk, and girder two ends can have overhanging semi girder; Portal crane has the features such as utilization of area rate is high, job area large, it is wide to adapt to, highly versatile, is used widely in goods yard, harbour.Portal crane can be by sash structure form, press girder form, by main beam structure, by purposes formal classification, but, traditional tire type gantry crane, in the time of driver and the upper and lower straddle truck of maintenance personal, generally have one section of approximately 5 meters of high vertical ladder, for many years, in operating process, all there is the phenomenon of falling in the upper and lower stretched process of driver and maintenance personal, the lighter sprains, and severe one has the danger of fracture.Therefore,, for above aspect, need to reasonably improve prior art.
Utility model content
For above defect, the utility model provide the upper and lower vertical ladder of a kind of personnel of raising safety, guarantee operating process smoothness, can avoid the upper and lower vertical ladder safety anti-falling device of straddle truck of personal injury, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
The upper and lower vertical ladder safety anti-falling device of a kind of straddle truck, comprise catching device, described catching device upper end is fixed on vertical ladder by buckling, be positioned at that catching device inside is provided with box of tricks and this box of tricks is connected with wire rope, described catching device lower end sets up a safety buckle and this safety buckle connects pull rope.
Correspondingly, described pull rope end is suspended from vertical ladder below, and described catching device upper end is by buckling on the horizontal beam that is fixed on vertical ladder.
The beneficial effect of the upper and lower vertical ladder safety anti-falling device of straddle truck described in the utility model is: by by catching device, upper and lower catching device installing tache, anti-fall pull rope combines, simultaneously, set up box of tricks in catching device inside, can improve the safety of the upper and lower vertical ladder of personnel, when the upper and lower vertical ladder of personnel, by rope by catching device safety buckle leave behind with personnel with it Special belt be connected, after climbing up vertical ladder, unclamp, if occur unexpected in the process of climbing, box of tricks by catching device detects excessive velocities, automatically take in the wire rope of catching device, the personnel that prevent are born, can effectively prevent the generation of security incident, guarantee that personnel can not come to harm in the process of upper and lower vertical ladder.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the upper and lower vertical ladder safety anti-falling device of straddle truck structural representation described in the utility model embodiment.
In figure:
1, vertical ladder; 2, buckle; 3, catching device; 4, safety buckle; 5, pull rope; 6, box of tricks.
The specific embodiment
As shown in Figure 1, the upper and lower vertical ladder safety anti-falling device of straddle truck described in the utility model embodiment, comprise catching device 3, described catching device 3 upper ends are fixed on vertical ladder 1 by buckling 2, be positioned at that catching device 3 inside are provided with box of tricks 6 and this box of tricks 6 is connected with wire rope, described catching device 3 lower ends set up a safety buckle 4 and this safety buckle 4 connects pull rope 5, and these pull rope 5 ends are suspended from vertical ladder 1 below.By catching device 3, safety buckle 4, anti-fall pull rope 5 are combined, simultaneously, set up box of tricks 6 in catching device 3 inside, can improve the safety of the upper and lower vertical ladder of personnel, when the upper and lower vertical ladder of personnel, by rope by catching device 3 safety buckles 4 leave behind with personnel with it Special belt be connected, after climbing up vertical ladder, unclamp, if occur unexpected in the process of climbing, box of tricks 6 by catching device 3 detects excessive velocities, automatically take in the wire rope of catching device 3, the personnel that prevent are born, can effectively prevent the generation of security incident.
The above-mentioned description to embodiment is can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various modifications to these examples easily, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement of making for this case and modification all should be in the protection domains of this case.
