Description
Technical field
The utility model relates to a kind of bridge construction device, particularly relates to a kind of bridge construction anti-drop device.
Background technology
In the middle of bridge construction process, it is a lot of that the work climbed down climbed up by needs, and safety problem also just can not be ignored naturally; China is injures and deaths numerous in bridge construction or other construction works every year; a main reason is that the safety device of construction equipment is perfect not; such as carry out in the bottom of bridge pavement spraying paint etc. construction time; need to adopt the equipment climbings such as ladder to get on to construct; equipment conventional is at present common ladder; substantially without the protection of safety device, therefore there is very large potential safety hazard.
Utility model content
The utility model is exactly for the problems referred to above, proposes a kind of bridge construction anti-drop device, and this device can prevent workman from work progress, fall event occurring well, even and if fall and also can guarantee safety.
For solving the problems of the technologies described above, a kind of bridge construction anti-drop device that the utility model provides, comprise the lift that two ends are hinged with bracing frame, described lift both sides have been threaded left handrail and right handrail respectively, described left handrail or right handrail are connected with the elastic webbing that some movable ends are connected with butt hook, and described left handrail or right handrail are provided with the cliver that can connect described butt hook; Be provided with one bottom described lift with the inflatable packer of electric inflating pump simultaneously, described lift top be provided be electrically connected with described electric inflating pump and the gauge tap of this electric inflating pump can be controlled.
Further, described lift top is provided with connecting ring, described connecting ring is hinged with enclosed elastic bar.
The utility model, by arranging elastic safety guard fence and arrange the mode of air cushion in bottom around ladder, farthest prevents workman to fall in work progress, thus greatly protects the life security of workman.

Shown in Fig. 1 is side of the present utility model appearance assumption diagram;
Shown in Fig. 2 is front appearance structure chart of the present utility model;
Wherein: 1, bracing frame; 2, lift; 3, left handrail; 4, right handrail; 5, butt hook; 6, elastic webbing; 7, cliver; 8, electric inflating pump; 9, inflatable packer; 10, gauge tap; 11, connecting ring; 12, enclosed elastic bar.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Composition graphs 1 and Fig. 2 known, a kind of bridge construction anti-drop device, comprise the lift 2 that two ends are hinged with bracing frame 1, lift 2 both sides have been threaded left handrail 3 and right handrail 4 respectively, left handrail 3 or right handrail 4 are connected with the elastic webbing 6 that some movable ends are connected with butt hook 5, left handrail 3 or right handrail 4 are provided with the cliver 7 that can connect this butt hook 5; Bottom lift 2, be provided with one with the inflatable packer 9 of electric inflating pump 8 simultaneously, lift 2 top be provided be electrically connected with electric inflating pump 8 and the gauge tap 10 of this electric inflating pump 8 can be controlled.
Workman, before climbing lift 2, first can be connected by the cliver 7 on the adjacent handrail of butt hook 5 on elastic webbing 6, thus prevent layback to fall; Simultaneously after climbing to top, gauge tap 10 can be pressed, by electric inflating pump 8, inflatable packer 9 is inflated, like this, also have inflatable packer 9 as protection even if fall.
Be provided with connecting ring 11 on lift 2 top, this connecting ring 11 is hinged with enclosed elastic bar 12.After being connected with corresponding fastening devices by connecting ring 11, the fixing and convenient effect of throwing off of safety can be played by enclosed elastic bar 12, thus ensure the event that can not to come off in fixation procedure.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
