Abstract
The utility model discloses a kind of seperated advance timbering top beams, two top beam bodies including seperated arrangement side by side, two top girder constructions are identical, and each top beam body includes: two pairs of needlings that top beam body front and rear portions are arranged in, and each pair of needling is horizontally arranged at interval along top beam body；Main reinforcement two sides are respectively welded stiffening plate in top beam between each pair of needling；Auxiliary support plate is respectively welded between each pair of needling and top beam top plate, each pair of needling is mutually welded with the auxiliary support plate respectively, constitutes box-structure between auxiliary support plate and the top beam top plate.The utility model advantage is that each top beam body is welded there are four needling, compared with conventional solution, can connect column quantity and promote one times, bracket support intensity is significantly promoted；Laterally above while there are two root posts to be supported in each top beam body simultaneously, support stability is higher.
Description
Technical field
The utility model relates to mine hydraulic brackets, more particularly, to seperated advance timbering top beam.
Background technique
Downhole crossheading tunnel is to modernize fully-mechanized mining working important material transportation and underground ventilating channel.Due to underground
Complex geologic conditions, terrane stress distribution are difficult to accurately calculate, and back is caused to deform, and roadway's sides inwardly squeeze contraction,
Personnel and equipment safety are directly affected, therefore the supporting of crossheading haulage drift is highly important.It is asked to solve above-mentioned roadway support
Topic mostly uses advanced hydraulic support to carry out mechanization supporting at present.
With the development of fully mechanized mining technology, mining depth is continuously increased, and coal mining transporting equipment develops to enlargement, underground coal mine
The height and width of gate road, which are also all complied with, increase, is broadening, and Underground pressure shows more acutely, especially in work of mining
At front 20-30 meters of industry working face, tunnel can largely be deformed, and advanced pressure is especially big, this just needs advanced hydraulic support to have
There are higher supporting intensity and stability.Direct contact component of the top beam as hydraulic support and top plate, structural strength and shape
Formula directly affects advanced hydraulic support to the supporting effect and service efficiency of back.Patent publication No. CN101191419,
Advance timbering top beam disclosed in CN101634230 uses split left and right formula, wherein being distributed two columns before and after each independent top beam
Nest is connected with column, this kind of structure type support stability is poor, and toppling property is strong；Surpass in patent CN201137500, CN2828315
Fore-stock top beam uses integral form, and top beam is divided into four needlings of cloth in vertical and horizontal respectively and connect with column, this kind of structure
Though ensure that the overall stability of bracket, bracket need to integrally move frame when mobile, and operating flexibility is poor.
Summary of the invention
The utility model aim is to provide a kind of seperated advance timbering top beam.
To achieve the above object, the utility model takes following technical proposals:
Fission advance timbering top beam described in the utility model, two top beam bodies including seperated arrangement side by side, two institutes
State that top girder construction is identical, and each top beam body includes: two pairs of needlings that top beam body front and rear portions are arranged in, each pair of column
Nest is horizontally arranged at interval along top beam body；Main reinforcement two sides are respectively welded stiffening plate in top beam between each pair of needling；It is each pair of
Auxiliary support plate is respectively welded between needling and top beam top plate, each pair of needling is mutually welded with the auxiliary support plate respectively, auxiliary
It helps between support plate and the top beam top plate and constitutes box-structure.
The utility model advantage major embodiment is in the following areas:
1, each top beam body is welded there are four needling, compared with conventional solution, can be connected column quantity and be promoted one
Times, bracket support intensity is significantly promoted；Laterally above while there are two root posts to be supported in each top beam body simultaneously, props up
Frame stability is higher.
2, stiffening plate is respectively welded in main reinforcement two sides in top beam, improves the cross-section surface intensity of main reinforcement in top beam, while meeting
Top beam overall width can be compressed under the premise of design requirement as far as possible, is not take up the other equipment arrangement spaces in tunnel.
3, each pair of needling is respectively welded on auxiliary support plate, and box knot is constituted between auxiliary support plate and top beam top plate
Structure, effectively increases the rigidity of structure of top beam body, and shock resistance is stronger.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of two top beam bodies of arrangement seperated side by side described in the utility model.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, seperated advance timbering top beam described in the utility model, two tops including seperated arrangement side by side
Beam body 1.1,1.2, two top beam bodies 1.1,1.2 structures are identical, are now illustrated by taking top beam body 1.1 as an example: before top beam body 1.1,
Rear portion is respectively arranged with two pairs of needlings 2,3, and each pair of needling 2,3 is horizontally arranged at interval along top beam body 1.1；Positioned at each pair of needling 2,3
Between top beam in 4 two sides of main reinforcement be respectively welded stiffening plate 5；It is respectively welded between each pair of needling 2,3 and top beam top plate 6 auxiliary
Support plate 7 is helped, each pair of needling 2,3 is welded with 7 phase of auxiliary support plate respectively, constitutes case between auxiliary support plate 7 and top beam top plate 6
Type structure.
