The specific embodiment
Consult Fig. 1, the utility model safety device 1 is applied on the jib 2 of hoisting crane (not indicating).Safety device 1 comprises first support 11, second support 12, safe stay cord 13 and ratchet fastener (not shown).
By above-mentioned setting, when on the needs jib 2 during operation, the safety strap that the workmen wears can conveniently be inserted on the safe stay cord 13, thereby prevents from falling down in the process of workmen's aloft work or safety misadventure such as fall on jib.The safe stay cord 13 that is arranged so that of ratchet fastener remains tension, further improves the aloft work safety.
Below in conjunction with Fig. 2 to Fig. 5 the utility model safety device is described in detail.
Welded and installed seat 17 is metal sheets, and the one end is soldered to first end of jib 2, the relative jib 2 unsettled settings of the other end.A plurality of first through holes (not shown) are set on the welded and installed seat 17.
The structure of first support 11 and second support 12 is similar.First support 11 comprises rack body 111, is arranged at the link 112 of rack body 111 1 ends, is arranged at the screw thread installation portion 113 of rack body 111 other ends and the stop section 114 that arranges near screw thread installation portion 113.Link 112 is used for connection stay cord 13, and stop section 114 is carried in the mounting sleeve portion 151, and screw thread installation portion 113 protrudes mounting sleeve portion 151 and by nut 115 first support 11 is secured to first carrier base 15.
Because first carrier base 15 is fixed to jib 2 by welded and installed seat 17, and second carrier base 16 is fixed to jib mount pad 4 by postive stop baffle 18.Therefore first carrier base 15 to the spacing of the axis of jib less than the spacing of second carrier base 16 to the axis of jib 2.In order to make safe stay cord 13 be parallel to the axis setting of jib 2, the rack body 121 of second support 12 is towards jib 12 curved design.Safe stay cord 12 be arranged in parallel with jib 2 axis, guarantees that the holdback force that workmen in use receives in each position of jib equates.
Further, the stop section 114 of first support 11 and second support 12,124 bottom position place arrange boss 116,126 respectively, and the mounting sleeve portion 151 of first carrier base 15, second carrier base 16,161 corresponding position arranges respectively and the recesses 155,165 of boss 116,126 couplings.Boss 116,126 cooperates with recess 155,165 respectively, prevents that first strut bar 11 and/or second strut bar 12 from rotating under stressing conditions.
In the present embodiment, the two ends of safe stay cord arrange the locking hook of the link 122 of the link 112 that is connected in first support 11 and second support 12 respectively, prevent the workmen when falling suddenly safe stay cord 13 in link 112 or link 122, come off.
Be different from prior art, the utility model safety device 1 is applied on the crane arm support 2, the safety strap that the workmen wears can conveniently be inserted on the safe stay cord, thereby prevent from falling down in the process of workmen's aloft work or safety misadventure such as on jib 2, fall, moreover, the ratchet fastener that arranges on the safety device 2 makes safe stay cord 13 remain tension, has further improved operational security.
Further, the easy disassembly of the utility model safety device, alerting ability height.Safe stay cord 13 is adjusted length by the ratchet fastener, can satisfy the demand of different jib length.
The utility model further provides a kind of hoisting crane, and this hoisting crane comprises the safety device described in the above-mentioned safety device embodiment.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
