Abstract
The utility model discloses digging tunnel face guard, belong to digging supporting field, including supporting guard beam, supporting guard beam forms colliery tunnel support, in addition to face guard, and one end of face guard is " u "-shaped crotch, the crotch of face guard one end is hooked on supporting guard beam, the other end of face guard is stretched out outside roadway support, and face guard is provided with multiple, and multiple face guards simultaneously form a face baffle plate together.Tunnel face guard of the present utility model can be with roadway support, in one protection face of upper formation of roadway support, the protection face can move extension with the extension of roadway support, and the staff or equipment for making working face are under the protection of protection face all the time, are advantageous to Safety of Coal Mine Production.
Description
Technical field
Digging supporting field is the utility model is related to, specifically, the utility model is related to a kind of digging tunnel face guard.
Background technology
Supporting is the stabilization and construction safety after underground passage excavates, and the structure for support, reinforcement or the coated country rock taken
The general name of part or other measures.During using traditional mining method construction, Support types with a hook at the end ore pillar, erection bracket, reinforce rock
Three kinds.
Coal mining tunnel is mostly coal road, is constructed using fully-mechanized digging machine.It is comprehensive excavated goods after, meet head on regular to use defense-help network
Sealed a mountain pass temporarily to meeting face, but two help can not advance support, side portion's wall caving falls cash accident and happens occasionally.For this this project team of phenomenon
The mode that the continuous shift-forward type of forestope uses is imitated, in advance with face guard, improves safety in production coefficient.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of coal mine roadway face guard, and the face guard can be with lane
Road construction speed shifts to an earlier date supporting, improves safety in production coefficient.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：Digging tunnel face guard, including
Supporting guard beam, the supporting guard beam form colliery tunnel support, in addition to face guard, and one end of the face guard is curved for " u "-shaped
Hook, the crotch of face guard one end are hooked on supporting guard beam, and the other end of face guard is stretched out outside roadway support, and the face guard is provided with
Multiple, multiple face guards simultaneously form a face baffle plate together.
Preferably, the face guard is provided with clamp with supporting guard beam contact position, face guard is contacted more with supporting guard beam
Step up close.
Using the technical solution of the utility model, following beneficial effect can be obtained：
Tunnel face guard of the present utility model can be protected with roadway support in the upper formation one of roadway support
Face, the protection face can move extension with the extension of roadway support, make working face staff or equipment be in all the time it is anti-
Under the protection of mask, be advantageous to Safety of Coal Mine Production.
Brief description of the drawings
Brief description is made to the content expressed by each accompanying drawing of this specification and the mark in figure below：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of face guard in Fig. 1；
Mark in above-mentioned figure is：1st, supporting guard beam；2nd, face guard；3rd, clamp；4th, crotch.
Embodiment
Below against accompanying drawing, by the description to embodiment, to specific embodiment of the present utility model as involved
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of each component, construction, each several part etc. make into
The detailed description of one step.
As shown in figure 1, this digging tunnel face guard includes supporting guard beam 1, supporting guard beam 1 forms colliery tunnel support, also
Including face guard 2, as shown in figure 1, one end of face guard 2 is " u "-shaped crotch 4, the crotch 4 of the one end of face guard 2 is hooked in supporting shield
On beam 1, the other end of face guard 2 is stretched out outside roadway support, and face guard 2 is provided with multiple, and multiple face guards simultaneously form one together
Face baffle plate, face guard 2 are provided with clamp 3 with the contact position of supporting guard beam 1, face guard 2 is contacted with supporting guard beam 1 even closer.
Tunnel face guard 2 can be with roadway support during use, and in one protection face of upper formation of roadway support, this is anti-
Mask can move extension with the extension of roadway support, the staff of working face or equipment is in the anti-of protection face all the time
Under shield, be advantageous to Safety of Coal Mine Production.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that methodology and technical scheme of the present utility model are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in the utility model
Protection domain within.
