The protection net disclosed by the utility model is relatively convenient and firm by regulating the whole height through the fixing device capable of being opened and closed on the front frame and the rear frame, and the net wires are inserted into the insert holes in the inner sides of the front frame and the rear frame, so that the protection net is simple in process and firm in structure, and is convenient and practical.
Description
Technical field
The utility model relates to protecting wire net, is specifically related to protecting wire net.
Background technology
In Coal mine excavation, safety in production is primary, and therefore the outfit of various Safety protectors is very important.Use hydraulic support in work, for the coal cinder that prevents from coming off injures the operating personnel by a crashing object, generally all be provided with protecting wire net in the front of hydraulic support.
Existing protecting wire net mostly is the wire gauze of braiding, and the edge joint weld of wire gauze is connected on the framework or passes through the iron wire bolt on framework, and the welding of twine and framework is more loaded down with trivial details, and long easy sealing-off of time one, more insecure with the iron wire bolt, therefore existing protecting wire net is made more loaded down with trivial details, and application life is short.It is inconvenient lift adjustment height according to hydraulic prop that existing protecting wire net also has a shortcoming, affects protection effect.
The utility model content
Technical problem to be solved in the utility model is to solve the protecting wire net complex manufacturing technology, and application life is short, highly regulates inconvenient problem.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts provides a kind of protecting wire net, comprise the framework of rectangle and be fixed on the interior a plurality of twines of described framework, described twine arranged crosswise, described framework comprises two forward and backward frameworks that forward lap and arrange, and but one of them described framework is provided with the fastening devices of folding, described fastening devices is fixed together described forward and backward framework, along circumferentially having a plurality of jacks, the two ends of described twine are inserted in respectively in the described jack on the medial surface of described forward and backward framework.
In above-mentioned protecting wire net, the infall of two described twines welds together.
In above-mentioned protecting wire net, described forward and backward framework is that cross section is the steel pipe of rectangle.
In above-mentioned protecting wire net, described twine is the stainless steel rod iron.
In above-mentioned protecting wire net, described fastening devices is fixed in the top of described front baffle and is two groups that arrange up and down, every group is two and is individually fixed on the left and right sides side of described front baffle, described fastening devices comprises stay hook, nylon block and bolt, described stay hook is that U-shaped and the outside are long limit, the inboard is minor face, the front end on described long limit is welded on the lateral surface of described front baffle, end is resisted against respectively on the described long limit about described afterframe, described nylon block is square and is positioned at described stay hook, described nylon block is resisted against on the trailing flank of described afterframe, and described bolt is screwed on the rear end of described stay hook and is resisted against on the described nylon block.
In above-mentioned protecting wire net, be welded with on the left and right sides side of described front baffle for the fixing connector of protecting wire net, have through hole on the described connector.
But the fastening devices of the protecting wire net that the utility model provides by folding on the forward and backward framework regulated whole height, and be convenient and firm, and twine is inserted in the jack of forward and backward framework inboard, and technique is simple, and sound construction is convenient and practical.
Description of drawings
The Facad structure schematic diagram of the protecting wire net that Fig. 1 provides for the utility model;
The left TV structure schematic diagram of the protecting wire net that Fig. 2 provides for the utility model;
The plan structure schematic diagram of the protecting wire net that Fig. 3 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the protecting wire net that the utility model provides comprises the forward and backward framework 1,2 of rectangle, forward and backward framework 1,2 setting that forward laps, be fixed with a plurality of twines 3 in the forward and backward framework 1,2, twine 3 arranged crosswise, the infall of twine 3 welds together, and has increased the fastness of protecting wire net.Along circumferentially having a plurality of jack (not shown)s, the two ends of twine 3 are inserted in respectively in the jack on forward and backward framework 1,2 the medial surface, and this inserting mode technique is simple, and sound construction is convenient and practical.Forward and backward framework 1,2 is for cross section is the steel pipe of rectangle in the present embodiment, and twine 3 is the stainless steel rod iron.
As shown in Figure 3, but front baffle 1 is provided with the fastening devices of folding, and fastening devices is fixed together forward and backward framework 1,2.Fastening devices is fixed in the top of front baffle 1 and is two groups that arrange up and down, every group is two and is individually fixed on the left and right sides side of front baffle 1, fastening devices comprises stay hook 4, nylon block 5 and bolt 6, stay hook 4 is that U-shaped and the outside are long limit 41, the inboard is minor face 42, the front end on long limit 41 is welded on the lateral surface of front baffle 1, end is resisted against respectively on the long limit 41 about afterframe 2, nylon block 5 is square and is positioned at stay hook 4, nylon block 5 is resisted against on the trailing flank of afterframe 2, and bolt 6 is screwed on the rear end of stay hook 4 and is resisted against on the nylon block 5.After unclamping bolt 6, afterframe 2 can move up and down at stay hook 4 interior relative front baffles 1, thereby regulates the height of protecting wire net; Behind the fastening nut 6, nut 6 withstands on nylon block 5 on the afterframe 2, thereby forward and backward framework 1,2 is fixed together, and this fixed form is simple and practical, is connected firmly, and it is convenient to adjust.
As shown in Figure 1, also be welded with on the left and right sides side of front baffle 1 for the fixing connector 7 of protecting wire net, have through hole on the connector 7, connector 7 can be screwed on the hydraulic support.
But the fastening devices of the protecting wire net that the utility model provides by folding on the forward and backward framework 1,2 regulated whole height, and be convenient and firm, and twine 3 is inserted in the jack of forward and backward framework 1,2 inboards, and technique is simple, and sound construction is convenient and practical.
