Description
Technical field
This utility model temporary support for drivage face, belongs to coal mining safety support technical field.
Background technology
The advance support of so-called driving face, refers to that at empty top control top in front of driving face meets head on gib
Plate, temporarily provides the supporting of protection for safety work, therefore, during anchor tunnelling, correct selection, reasonable employment are interim
Support form is for reinforcement roof control, it is ensured that safety in production, realizes driving face high-yield and high-efficiency important in inhibiting.But
The gib form for being used under my mine at present is the long girder steel of suspension for plank front-probe support, and what is existed during use mainly asks
Topic：1. meet geological structure, top board it is uneven when can not use；2. easily crumbled in gun diging face supporting, work is dug in machine
Make face easily to be knocked down by cutting head of roadheader, broken, while also restriction production, it is impossible to embody the high-yield and high-efficiency of comprehensive pick；3. interim
Shield is heavier, and during reach, man-hours requirement is more, Ren Yuanduo, high labor intensive；4. supporting area is little, it is impossible to the exposed coal petrography of comprehensive supporting
Body, has leaky roof phenomenon；5. gib poor safety performance, protects top effect poor；6. hinder the construction of permanent support.
Utility model content
This utility model overcomes the shortcomings of that prior art is present, and technical problem to be solved is to provide a kind of being applied to and digs
Enter the device of work surface gib, realize face contact totally-enclosed to top board, improve drivage efficiency and safe effect.
In order to solve above-mentioned technical problem, the technical scheme adopted by this utility model is：Temporary support for drivage face,
Including anchor pole, shield top rack, the long girder steel of suspension, back of the body jack rafter, face roof has the anchor pole of multiple spread configurations, against meeting head on
Two row's anchor poles on be provided with suspension ring, shield top rack be rectangular metal rack and its in the middle of be provided with reserved ring, shield top rack passes through
The long girder steel of at least three suspensions is fixed on face roof, and the middle long girder steel of suspension is through the reserved of shield top rack
Ring, the suspension is long, and girder steel is in the suspension ring that the one end met head on is arranged on anchor pole and its other end is by carrying on the back jack rafter
Fixation is sticked up.
Be coated with wire netting and open and steel band above the rack of the shield top, and the wire netting open with steel band by thin wire with
Shield top rack is buckled bundle and is fixed.
Shield top rack is the rigidity rack that 12# channel-section steels are welded into.
Multiple posts are supported by between the shield top rack and tunnel ground.
Described post is hydraulic safe point post.
This utility model is compared with the existing technology had an advantageous effect in that：This utility model is set using new safety
Apply --- shield top rack, support shield top rack to form totally-enclosed shield top utilities support top board with a post, form totally-enclosed face to top board
The new shield top of contact.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is planar structure schematic diagram of the present utility model.
Specific embodiment
As shown in figure 1, this utility model temporary support for drivage face, including anchor pole 1, the long steel of shield top rack 2, suspension
Beam 3, back of the body jack rafter 4, face roof 5 have the anchor pole 1 of multiple spread configurations, are provided with suspension ring on the two row's anchor poles 1 met head on,
Shield top rack 2 be rectangular metal rack and its in the middle of be provided with reserved ring, shield top rack 2 is by the long girder steel of at least three suspensions 3
It is fixed on face roof 5, the reserved ring of the middle long girder steel 3 of suspension through shield top rack 2, the long girder steel of the suspension
3 in the suspension ring that the one end met head on is arranged on anchor pole 1 and its other end has sticked up fixation by carrying on the back jack rafter 4.
Shield top rack 2 is coated with wire netting above and opens and steel band, and the wire netting is opened and passes through thin wire with steel band
Bundle is buckled with shield top rack 2 to fix.
Roadway supported by bolt it is common for rectangular cross section, shield top rack 2 adopts rectangle rack, and optimal choice is width 1m,
Length is determined according to span length, is roughly divided into two kinds：3.9m（Suitable span length 4.5m-4.6m）And 3.1m（It is adapted to
Span length 3.7m-3.8m）.
Shield top rack 2 is the rigidity rack that is welded into of 12# channel-section steels, its advantage be the structure rack comprcssive strength compared with
Greatly, it is less prone to system unstability.
Multiple posts are supported by between the shield top rack 2 and tunnel ground, support shield top rack to form full envelope with a post
Close shield top utilities support top board.
Described post is hydraulic safe point post, and its stroke is long, lightweight, easy to use.
Using method：
After meeting head on to blow out, to top board and meet head on to look for cash living in time, before work in every of meeting head on, carry out safe work first
Make；
The suspension ring of anchor pole are first installed on the two row's anchor poles met head on, and install the long girder steel of suspension of centre, will shield
Top rack is transported to meets head on to lift, and the middle long girder steel of suspension is reserved from the middle of the rack of shield top and penetrated in ring, upper neat both sides suspention
The long girder steel of formula, the long girder steel afterbody of three suspensions are fixed by a back of the body jack rafter 4 and hold up jointly shield and push up rack so as to contact work
Make face top board 5, reach the purpose on shield top；
If tunnel requires steel band supporting in lapping, in advance wire netting can be opened and be covered in shield top rack 2 together with steel band
On, and tied with thin wire button, then hold in the palm to meeting head on, the array pitch of capturing position, i.e. anchor pole is so required in upper shield top rack 2
And top anchor pole and the position relationship of center line, quick mounting nut is easy to use, it is once that anchor pole is first-class, after anchor pole is first-class, untie
Tied silk, unloads shield top rack 2, and unloads the long girder steel of suspension, suspension ring and other accessories, keep, prevent from deforming and damage.
The roof control of digging laneway it is important that roof control during empty top of meeting head on, by the improvement to gib,
So as in the phenomenon for fundamentally preventing the empty top operation of boring head, it is ensured that boring head management is fulfilled, to realizing essence peace
Have great significance entirely.
