Abstract
The utility model discloses an elevated safety net which comprises a cross rod. Both sides of the cross rod is symmetrically provided with supporting rods. The lower portion of the cross rod is provided with an elevated structure which comprises a sliding rail, a pulley wheel and a hand grip. The cross rod is symmetrically provided with chains. The lower end of the chains is provided with a pawl for hanging the safety net. The elevated safety net has the following benefits that the lower portion of the cross rod is provided with the elevated structure and the elevated structure comprises a sliding rail, a pulley wheel and a hand grip, so the dynamic go up and down of the safety net is achieved and can meet different requirements for construction height. In addition, the cross rod is further provided with the chains and the chains are provided with the pawl, so the erection of the safety net is achieved in the process of elevating the cross rod. The elevated safety net has the advantages of being flexible in operation, labor-saving and material-saving, thus improving the work efficiency.
Description
Technical field
The utility model belongs to building field, is specifically related to a kind of liftable safety net.
Background technology
Safety net is as the labor protection apparatus of a kind of prevention because of people or object fall injury, and the scope of application is extremely wide, mostly is used for various high-rise workings.The high-rise working hidden danger of falling often occurs in shelf, roof, window, suspension, dell, deep trouth etc. and locates.The fall injury degree, different, gently then wounded or disabled, heavy then dead with the falling distance size.Safety net protection principle is: the plain net effect is to block people and the thing that falls, and avoids or alleviate falling and thing wounds evil; Vertical net effect is to prevent that people or thing from falling.
Along with the development of society, the demand that builds a building is large, builds the increasing of worker building site, and the application of safety net is more frequent, and that existing safety net puts up is very inconvenient, consumes a large amount of man power and materials.
The utility model content
In order to solve problems of the prior art, the utility model provides a kind of liftable safety net of flexible operation.
The utility model is realized by following technical proposals:
Comprise cross bar, described cross bar two ends are arranged with respectively pole, and described cross bar bottom is provided with lifting structure, and described lifting structure comprises slide rail, pulley and hand crank, be arranged with chain on the described cross bar, the lower end of described chain is provided be used to the ratchet that hangs safety net.
Angle between the described symmetrically arranged pole is 45 °-180 °.
Be fixed with weight linear meter on the described pole.
Described cross bar, pole and weight linear meter are metal material.
Described chain is fixed on the cross bar by sprocket wheel.
Compared with prior art, the beneficial effects of the utility model are: the cross bar bottom is provided with lifting structure, and lifting structure comprises slide rail, pulley and hand crank, has realized the power lifting of safety net, can satisfy different construction height demands; Also be provided with in addition chain on the cross bar, chain is provided with ratchet, and cross bar has been finished setting up of safety net in the process of lifting, and flexible operation is saved human and material resources, has improved operating efficiency.

Fig. 2 is the structural representation of lifting structure;
Wherein, 1, cross bar, 2, weight linear meter, 3, chain, 4, ratchet, 5, safety net, 6, pole, 11, slide rail, 12, pulley, 13, hand crank.
The specific embodiment
With following embodiment the utility model is further explained, illustrated by reference to the accompanying drawings.
Shown in Fig. 1-2, a kind of liftable safety net, comprise cross bar 1, described cross bar 1 two ends are arranged with respectively pole 6, described cross bar 1 bottom is provided with lifting structure, described lifting structure comprises slide rail 11, pulley 12 and hand crank 13, is arranged with chain 3 on the described cross bar 1, and the lower end of described chain 3 is provided be used to the ratchet 4 that hangs safety net 5.
Angle between the described symmetrically arranged pole 6 is 45 °-180 °.
Be fixed with weight linear meter 2 on the described pole 6.
Described cross bar 1, pole 6 and weight linear meter 2 are metal material.
Described chain 3 is fixed on the cross bar 1 by sprocket wheel.
The course of work: at first by the fixing safety net of ratchet, then produce power by shaking hand crank, realize the lifting of safety net, wherein two poles can be 45 ° of angles, assist the rising of crossbeam, the convenient safety net of setting up.
A kind of liftable safety net of the utility model, the cross bar bottom is provided with lifting structure, and lifting structure comprises slide rail, pulley and hand crank, has realized the power lifting of safety net, can satisfy different construction height demands; Also be provided with in addition chain on the cross bar, chain is provided with ratchet, and cross bar has been finished setting up of safety net in the process of lifting, and flexible operation is saved human and material resources, has improved operating efficiency.
