Abstract
The utility model discloses a kind of driving face in coal mine split blade type defense-help network, belong to driving face in coal mine apparatus field, driving face in coal mine split blade type defense-help network, comprise external frame and wire side, external frame is ladder-shaped frame, and shape and the external frame of wire side adapt, and the two ends, left and right of wire side are fixed on inside ladder-shaped frame, wire side has a slice at least, and the requirement according to the different face area in tunnel increases or reduces the quantity of wire side.Split blade type defense-help network of the present utility model is easy to operate, piecemeal protection can be carried out in time to end face of meeting head on, there is feature safely and efficiently, effectively can prevent because wall caving, leakage spoil bring injury to construction operation personnel, thus ensure construction operation personnel personal safety.
Description
Technical field
The utility model relates to driving face in coal mine apparatus field, and specifically, the utility model relates to driving face in coal mine split blade type defense-help network.
Background technology
Wall caving refers to mine, tunnel, culvert excavation, in lining cutting process because of excavation or supporting improper, sidewall is out of shape under action of underground, destroys and the phenomenon that comes off.In mining, modal accident is exactly wall caving, accounts for more than 40% of mining accident.
For preventing wall caving, current common practices pastes side post for beating.If face of adopting is met geological structure, is had trickle, easy wall caving, according to on-site actual situations take the circumstances into consideration every a dozen one or beat to paste and help post strengthening supporting, help with little backboard if desired.The location large to face pressure also needs to carry out injecting glue solidification coal body, prevents wall caving to hurt sb.'s feelings.Especially, in the construction of soft-rock tunnel frame canopy, adopt forestope as temporary lining, though there is certain safety guarantee, during soft rock construction or easily wall caving and security incident occurs.
The end face or use individual prop to coordinate large plate to protect of meeting head on is fixed on after the end face protection that simultaneously driving face is met head on traditional adopts monolithic structure perforating, protective equipment erection procedure is complicated, result of use is poor, and can only install again after rolling at goods, be directly exposed to when protecting without end face time during workman's shipment, effectively can not protect workman.
How to accomplish operating personnel driving face just meeting head on along car, perforating, dig two help to dig the working procedures such as i iron hamstring, shipment time; do not occur because coal wall caving of meeting head on injures the accident of operating personnel by a crashing object, accomplish that construction is one of difficult point of driving face safety management under safeguard protection state.
Summary of the invention
It is simple, easy for installation and ensure the defense-help network of constructor's safety that technical problem to be solved in the utility model is to provide a kind of structure.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: driving face in coal mine split blade type defense-help network, comprise external frame and wire side, described external frame is ladder-shaped frame, shape and the external frame of wire side adapt, the two ends, left and right of wire side are fixed on inside ladder-shaped frame, and wire side encloses formed section and drift section matches, and is close to end face of meeting head on.
Preferably, described wire side has a slice at least, and the requirement according to the different face area in tunnel increases or reduces the quantity of wire side.
Preferably, described external frame horizontal gird is arranged three station posts, described station post is fixedly connected with wire side.
Preferably, described station post is multi-section structure, increases or reduce the joint number of station post as required, is connected between two joints by connecting pin.
Preferably, uniform installing hole on described horizontal gird, column top of standing arranges screw and is cemented on installing hole.
Preferably, described station post is provided with hook, and wire side hangs on hook.
Preferably, described wire side mesh is regular hexagon, and wire side adopts flame-retardant rope braiding to form.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
Split blade type defense-help network convenient disassembly of the present utility model, piecemeal protection can be carried out in time to end face of meeting head on, there is feature safely and efficiently, effectively can prevent because wall caving, leakage spoil bring injury to construction operation personnel, thus ensure construction operation personnel personal safety.
Accompanying drawing explanation
Brief description is made to the content expressed by each accompanying drawing of this manual and the mark in figure below:
Fig. 1 is the structural representation of the utility model split blade type defense-help network;
Fig. 2 is the structural representation of post of standing in Fig. 1;
Mark in above-mentioned figure is: 1, external frame; 11, horizontal gird; 12, installing hole; 2, wire side; 3, to stand post; 31, screw; 32, connecting pin; 33, link up with; 4, tunnel.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operating principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As shown in Figure 1, whole split blade type defense-help network is divided into two parts, upper portion, hypomere part are made up of two little trapezoidal defense-help network faces 2 respectively, and increase the quantity hanging over wire side 2 on the post 3 of station according to actual needs, wire side 2 adopts flame-retardant rope to be woven into orthohexagonal mesh.Three station post 3 side-by-side parallel are fixed on the horizontal gird 11 of external frame 1, horizontal gird 11 are evenly equipped with installing hole 12, and post 3 of standing is screwed in installing hole 12 fixing by the screw 31 on top.As shown in Figure 2, post 3 of standing is made up of plurality of sections of steel pipes, is connected between steel pipe by connecting pin 32, can increase the length of station post 3 so as required, thus can the more wire side 2 of carry.Wire side 2 hangs on the post 2 of station by the hook 33 on the post 3 of station, and post 3 of standing plays strengthens wire side 2 fixing in external frame 1, prevents wire side 2 from causing because area is excessive slack and undisciplined, affects result of use.Because each station post 3 has multiple hook 33, so can by the height regulating wire side 2 position hung on hook 33 to regulate wire side 2, flexible modulation wire side 2.
During use, the external frame 1 of this defense-help network is fixed on pit barring, pit barring supported laneway 4, prevent tunnel 4 from caving in, wire side 2 encloses formed section and tunnel 4 section matches, and be close to end face of meeting head on, the coal on the wall of lane, tunnel 4 drops in wire side 2, thus avoid and injure the accident of operating personnel by a crashing object because rib of meeting head on drops.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
