Abstract
The utility model discloses a kind of seperated advance timbering pedestals, two base bodies including seperated arrangement side by side, two base body structures are identical, and each base body includes: two pairs of needlings that base body front and rear portions are arranged in, and each pair of needling is horizontally arranged at interval along base body;The two sides of main reinforcement are respectively welded stiffening plate in pedestal between each pair of needling;Auxiliary support plate is respectively welded between each pair of needling and base plate, each pair of needling is mutually welded with the auxiliary support plate respectively, constitutes box-structure between auxiliary support plate and the base plate;It is respectively arranged with a pair of of advancing jack in the front and back ends of base body, fixedly connected to the inner side box pedal channel positioned at base body.The utility model advantage is that bracket support intensity is significantly promoted;Horizontally there are two root posts to be supported simultaneously, support stability is higher.
Description
Technical field
The utility model relates to mine hydraulic brackets, more particularly, to seperated advance timbering pedestal.
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, the continuous increasing of mining depth
Add, coal mining transporting equipment develops to enlargement, and the height and width in coal mine downhole crossheading tunnel, which are also all complied with, increase, has increased
Width, so that Underground pressure shows more acutely, especially at the front 20-30 rice of coal mining activity working face, tunnel can big quantitative change
Shape, advanced pressure is especially big, this just needs advanced hydraulic support to have higher supporting intensity and stability.Pedestal is as hydraulic
The most important load-carrying construction part of bracket, structural shape and intensity not only directly affect the support efficiency of advanced hydraulic support, and
And using effect of the advanced hydraulic support in roadway support is also directly influenced, while being also the basis of support stability.It passes
The advance timbering pedestal of system uses split left and right structure, wherein two needlings of distribution are connected with column before and after each independent seats,
But the support stability of this structural shape is poor, is easy to topple.
Summary of the invention
It is advanced that the utility model aim is to provide the fission that a kind of structural strength is high, support stability is good, to move booster big
Bracket base.
To achieve the above object, the utility model takes following technical proposals:
Fission advance timbering pedestal described in the utility model, two base bodies including seperated arrangement side by side, two institutes
State that base body structure is identical, each base body includes: two pairs of needlings that base body front and rear portions are arranged in, each pair of column
Nest is horizontally arranged at interval along base body;The two sides of main reinforcement are respectively welded stiffening plate in pedestal between each pair of needling;Often
To auxiliary support plate is respectively welded between needling and base plate, each pair of needling is mutually welded with the auxiliary support plate respectively,
Box-structure is constituted between auxiliary support plate and the base plate;A pair of of passage is respectively arranged in the front and back ends of base body
Jack fixedly connected to the inner side box pedal channel positioned at base body.
The utility model advantage embodies in the following areas:
1, side by side each pedestal of two base bodies of seperated arrangement weld there are four needling, with conventional solution phase
Than connection column quantity promotes one times, and bracket support intensity is significantly promoted;Horizontally there are two root posts to be propped up simultaneously
Support, support stability are higher.
2, stiffening plate is welded in main reinforcement two sides in the pedestal between each pair of needling, and it is horizontal to not only increase main reinforcement in pedestal
Section intensity, and the overall width of base body can be compressed under the premise of meeting design requirement as far as possible, positioned at base body
It is fixedly connected to the inner side box pedal channel, ensure that pedestrian space in the middle part of tunnel.
3, each pair of needling is welded on auxiliary support plate, and it is empty that box is formed between auxiliary support plate and understructure body
Between, this kind of structure type effectively increases the rigidity of structure of base body, and shock resistance is stronger.
4, it is separately positioned on a pair of of advancing jack of base body front and back ends, considerably increases drive of the pedestal when moving frame
Power, it is more steady that pedestal moves frame.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model conceals the advancing jack.
Fig. 2 is the structural schematic diagram of two base 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 pedestal described in the utility model, two bottoms including seperated arrangement side by side
Pedestal 1.1,1.2, two base bodies 1.1,1.2 structures are identical, include (being now illustrated with base body 1.1): being arranged the bottom of at
Two pairs of needlings 2,3 of 1.1 front and rear portions of pedestal, each pair of needling 2,3 are horizontally arranged at interval along base body 1.1;Positioned at each pair of needling
2, the two sides of main reinforcement 4 are respectively welded one piece of stiffening plate 5 in the pedestal between 3;Divide between each pair of needling 2,3 and base plate 6
It is not welded with auxiliary support plate 7, each pair of needling 2,3 is welded with 7 phase of auxiliary support plate respectively, auxiliary support plate 7 and base plate 6
Between constitute box-structure;It is respectively arranged with a pair of of advancing jack 8.1,8.2 in the front and back ends of base body 1.1, is located at pedestal
Body 1.1 fixedly connected to the inner side box pedal channel 9.
