The moving type security plain net
Technical field
The utility model relates to a kind of moving type security plain net.
Background technology
In the engineering construction process, often need carry out work high above the ground, except personal protection apparatus such as needs wear safety belt, also need below the operating area, set up measures such as safe plain net and protect during operation.
Traditional means of defence is to choose steel pipe outside on scaffold and spread safe plain net and protect.It is slower that this means of defence is set up speed, and, activity duration less in amount of high-altitude operation is short and job area when big, and apparent is economical inadequately.
Summary of the invention
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of moving type security plain net, and it is not only simple in structure; Easy to use, all can use whenever and wherever possible, and production and installation is simple and convenient; Can reuse, practice thrift wide variety of materials and human input.
The utility model technical scheme is to constitute like this, and a kind of moving type security plain net is characterized in that: it comprises support, crosses at above protective screening of one deck on the support and the mobile device that is connected in frame bottom.
In order further to strengthen protection effect, the quantity of said protective screening be two-layer more than, and each layer protective screening laid from top to bottom.
During field operation, can make several moving type security plain nets as required, be arranged in the scope that needs protection, when the operation personnel movement, promote the moving type security plain net accordingly, can satisfy the protection needs to the position that needs protection.
Compared to prior art, the utlity model has following advantage: the utility model is not only simple in structure, and is easy to use, all can use whenever and wherever possible, and production and installation is simple and convenient, can reuse, and practiced thrift wide variety of materials and human input.
Description of drawings
Fig. 1 is the example structure sketch map of a kind of moving type security plain net of providing of the utility model.
Label declaration among the figure: 1, protective screening, 2, castor, 3, montant or vertical tube, 4, cross bar or transverse tube.
The specific embodiment
Below in conjunction with the Figure of description and the specific embodiment the utility model content is elaborated:
Be illustrated in figure 1 as a kind of moving type security plain net that the utility model provides, it is characterized in that: it comprises support, crosses at above protective screening 1 of one deck on the support and the mobile device that is connected in frame bottom.
The quantity of said protective screening 1 be two-layer more than, and each layer protective screening 1 laid from top to bottom.
Said mobile device is made up of castor 2, and as required, said mobile device also can drive the device that support is movably walking by the guide wheel guide assembly that cooperatively interacts or other and constitute.
Said support is by being fixedly connected on montant or the vertical tube 3 around the protective screening 1 and being connected between adjacent two montants or the vertical tube 3 and the cross bar or the transverse tube 4 that are positioned at protective screening 1 below constitutes.
