Description
Technical field
The utility model relates to colliery technical field of operation, particularly relates to a kind of joist structure.
Background technology
Support is the necessary equipment of underground coal mine, plays the important function supporting tunnel.Joist is a square body structure.Joist is arranged in the rail groove below set cap with safety hanging device, can along back timber bottom surface forward slip.
When any frame support prepares to move forward, the column of this support is unloaded and mention, and at this moment back timber drops on joist, carries the back timber in reach by joist.
If the support of full face can be connected into as a whole, the resistance to overturning of support just can be strengthened.In addition, when joist has certain gradient relative to back timber, joist is just difficult to slide swimmingly along the rail groove on back timber, even if slide reluctantly, also easily forms the phenomenon of draw-in groove.
Utility model content
The purpose of this utility model is to provide a kind of joist and the modular support joist unit that can be connected easily between joist for entirety, and there will not be draw-in groove phenomenon when sliding along the rail groove of back timber.
For achieving the above object, modular support joist unit of the present utility model is included in the box-shaped joist of parallel two of being arranged side by side in cuboid in same level, two joist structure are identical, and joist top face is interval with two terminal pads for being slidably connected with the rail groove on set cap; Be provided with sleeve in joist below each terminal pad, be provided with telescopic mast in sleeve, sleeve bottom end stretches out joist downwards;
The bottom fixed cover of telescopic mast is connected to the platen of annular, and the telescopic mast between platen and joist roof is arranged with stage clip; The top of described telescopic mast protrudes upward joist and is connected with junction plate, and described terminal pad is fixedly connected on junction plate;
The both ends of described joist are equipped with joist pin-and-hole, and joist one end is arranged with joist cover, and joist puts and is parallelly provided with two side by side and overlaps pin-and-hole with for the joist corresponding with joist pin-and-hole; Two joists cover pin-and-hole be respectively used to be docking together two joists on joist pin-and-hole corresponding;
Joist cover is by being fixedly connected on joist through the straight pin of described joist cover pin-and-hole and joist pin-and-hole and the cottor pin that is located in straight pin end;
Linked together by two parallel adapter sleeves be arranged side by side between two joists of described modular support joist unit.
In two joists of described modular support joist unit, the middle part of at least one joist is provided with the connecting pin running through joist up and down, connecting pin top is stretched out joist and is formed the forced section for connecting jack, and forced section is fixed together by fixed head and joist.
Multiple modular support joist unit of the present utility model can be linked together by joist cover, form an overall structure, thus strengthen the resistance to overturning of support.
When joist is out-of-level, between the back timber that joist is coupled, there is the gradient of a bit.Terminal pad is slidably connected in the rail groove on back timber, when a certain terminal pad to be subject to power upwards because joist is out-of-level, upwards can pull telescopic mast thus relatively joist moves up certain distance, ensure that terminal pad can not be stuck in rail groove, avoid draw-in groove phenomenon.The setting of stage clip, can ensure when not stressing, terminal pad can automatically reset, and ensures that terminal pad can not Free Slosh.
The extension bar of jack and the forced section of connecting pin hinged, the setting of connecting pin is convenient to connect jack, thus moves integrally the utility model.
Traditionally during structure fabrication joist, 2 riveter and electric welders are needed to spend just can complete one 6 man-hours.And during by structure fabrication extensible canopy of the present utility model, then only need 2 riveter and electric welders to spend just can complete one 3 man-hours.The utility model both can ensure the requirements such as supporting structure stability, intensity, greatly enhanced productivity again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, modular support joist unit of the present utility model is included in the box-shaped joist 1 of parallel two of being arranged side by side in cuboid in same level, two joist 1 structures are identical, and joist 1 top face is interval with two terminal pads 2 for being slidably connected with the rail groove on set cap; Be provided with sleeve 3 in joist 1 below each terminal pad 2, be provided with telescopic mast 4 in sleeve 3, sleeve 3 bottom stretches out joist 1 downwards;
The bottom fixed cover of telescopic mast 4 is connected to the platen 5 of annular, and the telescopic mast 4 between platen 5 and joist 1 roof is arranged with stage clip 6; The top of described telescopic mast 4 protrudes upward joist 1 and is connected with junction plate 7, and described terminal pad 2 is fixedly connected on junction plate 7;
The both ends of described joist 1 are equipped with joist pin-and-hole 8, and joist 1 one end is arranged with joist cover 9, parallelly on joist cover 9 are provided with two side by side and overlap pin-and-hole 10 with for the joist corresponding with joist pin-and-hole 8; Two joists cover pin-and-hole 10 be respectively used to be docking together two joists 1 on joist pin-and-hole 8 corresponding;
Joist cover 9 is by being fixedly connected on joist 1 through the straight pin 11 of described pin-and-hole (comprising joist cover pin-and-hole 10 and joist pin-and-hole 8) and the cottor pin 12 that is located in straight pin 11 end.
Linked together by two parallel adapter sleeves 13 be arranged side by side between two joists 1 of described modular support joist unit.Adapter sleeve 13 is made up of square tube.Square tube wall thickness selects 10-12mm.
In two joists 1 of described modular support joist unit, the middle part of at least one joist 1 is provided with the connecting pin 14 running through joist 1 up and down, connecting pin 14 top is stretched out joist 1 and is formed the forced section 15 for connecting jack, and forced section 15 is fixed together by fixed head 16 and joist 1.Structural strength when fixed head 16 can strengthen stressed.
Described telescopic mast 4, straight pin 11, cottor pin 12, connecting pin 14, set cap and rail groove, column etc. are prior art, and figure does not show described column, set cap and rail groove thereof.
During use, multiple modular support joist unit of the present utility model can be docking together, and joint uses same joist to overlap 9 connections, two joists be docking together 1, and joist cover 9 is connected with joist 1 with cottor pin 12 by straight pin 11.Therefore, multiple modular support joist unit of the present utility model can be linked together by joist cover 9, form an overall structure, thus strengthen the resistance to overturning of support.
When joist 1 is out-of-level, between the back timber that joist 1 is coupled, there is the gradient of a bit.Terminal pad 2 is slidably connected in the rail groove on back timber, when a certain terminal pad 2 is subject to power upwards because joist 1 is out-of-level, can upwards pull telescopic mast 4 thus relatively joist 1 moves up certain distance, ensure that terminal pad 2 can not be stuck in rail groove.The setting of stage clip 6, can ensure when not stressing, terminal pad 2 can automatically reset, and ensures that terminal pad 2 can not Free Slosh.
The setting of connecting pin 14 is convenient to connect jack.During work, the extension bar of jack and the forced section 15 of connecting pin 14 hinged.During mobile joist 1, the masthead that stretches out of jack presses connecting pin 14, thus drives joist 1 to move integrally.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
