In order to achieve the purpose, the utility model adopts the technical scheme as follows: the utility model provides a light-duty safety device of hoist walking passageway, includes two crane girders, two the top of crane girder slides and is equipped with the monkey, two one side that the top of crane girder is close to each other all is equipped with the support post, be equipped with two speed differentiators on the support post, the leading-out terminal of speed differentiator is connected with the protection network, and the one end that the speed differentiator was kept away from to the protection network is connected with the monkey.
Preferably, two fixing rings are arranged on the crane trolley, two hooks are arranged at one end, away from the speed difference device, of the protective net, and the hooks are sleeved on the fixing rings.
Preferably, the height of the support column is 1500mm, and a reinforcing rib is arranged between one side of the bottom of the support column and the crane main beam.
Preferably, a travelling rail is arranged on the crane girder, and the crane trolley is arranged on the travelling rail in a sliding manner.
Preferably, a guardrail is arranged on one side of the top of the crane main beam, and the diameter of the grid on the protective net is 100mm.
Preferably, two suspension points are arranged on the support upright, and the speed differentiator is arranged on the suspension points.
Compared with the prior art, the utility model has the advantages of:
through setting up the support post, the speed differentiator, the protection network, the monkey, driving track and couple isotructure, wherein the monkey can drive the protection network and move about, the protection network can stimulate the speed differentiator and stretch the activity simultaneously like this, make things convenient for the drawing of protection network, when the operation personnel fall to the passageway inboard because of the accident, the protection network drives speed differentiator variable speed automatic locking and dies, effectively block the personnel eminence of empting and fall, this scheme simple structure, and the modern design, make things convenient for the monkey to carry out normal operating through setting up protection network and speed differentiator, can not bring the hindrance for the monkey, utilize the speed differentiator to carry out the auto-lock when taking place the accident, thereby it is fixed to hold the protection network, can prevent that personnel's eminence from falling like this, effectively protect operation personnel's walking safety.
