The light type shield type temporary support facility for roadway excavation has the advantages that in the excavation process, the temporary support facility is light, the forward stretching is convenient, the assembly and the disassembly are convenient, the roof control is timely, the labor intensity of workers is reduced, and the work efficiency is improved. The light type shield type temporary support facility has the characteristics that the structure is simple and light, the support effect is good, the structure is simple, the operation is convenient and the like, so that the field adaptability is higher, and the occurrence of the roof accidents can be effectively avoided.
Description
Technical field
The utility model relates to a kind of colliery digging laneway temporary support, the light-duty protected type temporary lining of especially a kind of digging laneway facility.
Background technology
Bolt support driving face, the temporary lining important construction link that is absolutely necessary." roof control detailed rules for the implementation " regulation: driving face is between the permanent support, must use falsework, or the metal cantilever timbering, forbids the operation of sky top.
The temporary lining facility that each driving face of present domestic colliery uses mostly is suspension drifting roof and point of safes post.Drifting roof generally adopts Φ 57mm * 3500mm steel pipe processing.Though it is simple in structure, use also uncomplicated.But move inconvenience when the driving of upper and lower mountain, result of use is bad when roof cracking or top board out-of-flatness.Mainly showing as drifting roof sticks up less than top board or because of top board rises and falls and causes the drifting roof reach untimely etc.Point of safes post heaviness, the control top area is little, and globality is bad, does not also have the effect of temporary lining usually, is unfavorable for safety in production.The on-the-spot bad adaptability of driving face temporary lining facility drifting roof or point of safes post, supporting effect is bad, is unfavorable for safety in production.
Summary of the invention
The purpose of this utility model is to provide a kind of: the light-duty protected type temporary lining of digging laneway facility, solution big gun pick lane space is little, construction technology is complicated, the unmanageable problem of roof cracking.
The purpose of this utility model is achieved in that this supporting facility comprises Hu Ding hurdle, Chain block, connecting rod and hanging hook, the rear end that on first row's roof timbering anchor pole, connects the Hu Ding hurdle, on first row's roof timbering anchor pole, be connected with Chain block simultaneously by hanging hook, connecting rod is an eighty percent discount, be that first connecting rod and second connecting rod join end to end, Chain block is connected with the second connecting rod of connecting rod break section, be connected with an end of second connecting rod by hanging hook on second row's roof timbering anchor pole, the other end of first connecting rod is connected with the centre position on Hu Ding hurdle.
Beneficial effect, owing to adopted such scheme, this device mainly is made up of Hu Ding hurdle, hinged quadric chain and Chain block three parts.Hu Ding hurdle, hinged quadric chain adopt steel pipe processing, constitute to stick up top mechanism, and be light and simple in structure, installation and easy to operate.By operating the motion state of hinged quadric chain, realize protecting the top temporarily.By utilizing Chain block to control this motion of mechanism state, stick up the top thereby realize protecting the top.After the Hu Ding hurdle is raised to top board, the artificial operation Chain block that continues, its pulling force is delivered to the top board of the empty top zone of meeting head on by quadric chain, gives setting load of top board.It is big to protect top area, and the constructor has spacious more safety operation space.
1. the Hu Ding hurdle of design adopts Φ 18.5mm steel pipe and the processing of Φ 10mm reinforcing bar, and the about 20kg of weight is convenient to carrying, installs and is used.
2. the Hu Ding hurdle mode taking to hang rotation is protected the top, and is simple to operate.On-the-spot compliance is strong.
3. on the Hu Ding hurdle, arrange the steel band hook, hooking into the Hu Ding hurdle, to hang the design length of side be the array pitch of an anchor pole, with steel band, wire lath hang over hook go up rotate to top board with the Hu Ding hurdle after, in the steel band hole, directly beat the bolt support top board, be convenient to control the anchor pole array pitch.
Solved that big gun pick lane space is little, construction technology is complicated, the unmanageable problem of roof cracking, reaches the purpose of this utility model.
Advantage: in the tunneling construction light, the preceding spy of temporary lining facility convenient, be convenient to install and remove, the control top in time, reduce worker's labour intensity, improve work efficiency.Realize temporary lining, avoid the operation of sky top.The temporary lining facility can not only play the effect of temporary lining top board, and have the control top area big, simple and light, characteristics such as supporting effect is good, simple in structure, and is easy to operate have been improved the operating environment of boring head, on-the-spot compliance is stronger, thereby has effectively avoided the generation of roof accident.

The specific embodiment
Embodiment 1: this supporting facility comprises Hu Ding hurdle 1, Chain block 2, connecting rod 3 and hanging hook 4, the rear end that on first row's roof timbering anchor pole, connects Hu Ding hurdle 1, on first row's roof timbering anchor pole, be connected with Chain block 2 simultaneously by hanging hook 4, connecting rod 3 is an eighty percent discount, be that first connecting rod and second connecting rod join end to end, Chain block 2 is connected with the second connecting rod of connecting rod 3 break sections, be connected with an end of second connecting rod by hanging hook 4 on second row's roof timbering anchor pole, the other end of first connecting rod is connected with the centre position on Hu Ding hurdle.
The course of work: 1. the Hu Ding hurdle is hung on suspension ring, and networking hangs over colluding for a short time of Hu Ding hurdle to steel band.Link assembly and Hu Ding hurdle is hinged.
2. the manually-operated Chain block is controlled hinged quadric chain, makes Hu Ding hurdle band steel band and wire lath rotates together, till being adjacent to top board.
3. after the Hu Ding hurdle is adjacent to top board, use roof-bolter to carry out bolt support.
