Description
Technical field
The utility model relates to a kind of road pillow, specifically, relates to a kind of U-bolt formula cement road pillow.
Background technology
The road pillow claims again sleeper or sleeper, belongs to one of railway casting.Road pillow original adoption timber is made, and after the World War II, because various countries' timber lacks, the road pillow that gradually adopts concreting to form is commonly called as " cement road pillow ", and cement road pillow has economical with materials, long service life, characteristics that track stability is good.
In the hole, mine ore deposit in colliery, for the ease of carrying mineral aggregate, usually adopt middle-size and small-size railcar, correspondingly, can normally use in order to make railcar, need to lay track.Lay at present track and generally use spike-type, T-shaped bolt type, pre-buried lockpin-type road pillow etc., in use, be easy to cause security incident because long-time vibrations make bolt looseness cause track to come off; And the acid colliery water that contains free sulfuric acid that exists in the hole, mine ore deposit in colliery has corrosiveness to metal, is easy to corrode pre-buried metal fastener, can cause equally bolt looseness to come off and causes security incident.
The utility model content
The purpose of this utility model is to provide a kind of U-bolt formula cement road pillow, and the structure that solves present cement road pillow connects unreasonable and has the problem of serious security incident hidden danger.
To achieve these goals, the technical solution adopted in the utility model is as follows:
U-bolt formula cement road pillow comprises by steel concrete and builds the road pillow body that forms, and is used for connecting U-bolt and the nut of road pillow body, and is used for fixing pressing plate; The upper lateral of described road pillow body is provided with two pairs of perforations through hole up and down, two pairs of through holes are symmetrical with the longitudinal centre line of road pillow body, pressing plate is arranged at pillow body top, and U-bolt passes successively through hole and pressing plate and is connected and fixed with nut from pillow body bottom, road.
Further, be provided with the draw-in groove of being convenient to place U-bolt that is interconnected between every pair of through hole of pillow body bottom, described road.
In order to increase application life, described road is rested the head between body and the pressing plate and is equipped with pad in the draw-in groove.
For economical with materials, described pad is made by elastomeric material, and this pad adopts elastomeric material waste and old in the colliery to make usually.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model is simple in structure, and is cheap, easy to use, is fit to apply.
(2) the utility model adopts U-bolt to be connected and fixed, the nut difficult drop-off, and the architectural characteristic of utilizing U-bolt self makes pillow body and track interfix effectively, even nut loosening, track is dropped from road pillow body, thereby greatly improved safety in utilization of the present utility model.
(3) road of the present utility model is rested the head on body and is provided with the through hole corresponding with the U-bolt shape and draw-in groove, it is stable fixing after U-bolt is installed, be difficult for sliding and break away from, further improve safety, and avoided metal fastener pre-buried in the existing road pillow easily by the shortcoming of acid colliery aqueous corrosion.
(4) the utility model utilize pressing plate with track fixing with road pillow body on, increased the degree of fixation of track, thereby improved safety.
(5) the utility model is provided with rubber sheet gasket, slows down railcar through the jerk of out-of-date generation, has improved application life, and this rubber adopts elastomeric material waste and old in the colliery usually, and raw material has been saved in twice laid.
(6) the utility model uses U-bolt directly and the road is rested the head on the body through hole and draw-in groove are fixed, metal parts by acid colliery aqueous corrosion after, only needing to change corresponding metal parts gets final product, road pillow body itself does not damage, can reuse, the manufacturing that has reduced road pillow body drops into, thereby has saved cost.
Description of drawings
Fig. 1 is the plan structure schematic diagram of pillow body in road in the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is that the utility model uses view.
In the above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
Shown in Fig. 1～3, U-bolt formula cement road pillow is mainly used in the delivery track in the hole, mine ore deposit in colliery, comprises by steel concrete and builds the road pillow body 1 that forms, and is used for connecting U-bolt 2 and the nut 3 of road pillow body, and is used for fixing pressing plate 4; The upper lateral of described road pillow body 1 is provided with two pairs of perforations through hole 11 up and down, two pairs of through holes are symmetrical with the longitudinal centre line of road pillow body, its spacing is corresponding with the track width on being installed on pillow, pressing plate 4 is arranged at pillow body top, and U-bolt 2 passes successively through hole and pressing plate and is connected and fixed with nut 3 from pillow body bottom, road.Be provided with the draw-in groove 12 of being convenient to place U-bolt that is interconnected between every pair of through hole of pillow body bottom, road.Described road is rested the head between body 1 and the pressing plate 4 and is equipped with pad 5 in the draw-in groove 12, and this pad is made by elastomeric material, and this pad adopts elastomeric material waste and old in colliery to make usually, and twice laid economizes in raw materials.
In the actual use procedure, a road pillow body is furnished with 2 U-bolts, 4 nuts, 4 pressing plates, 4 pads, and two tracks.Track is generally the track of I shape, the bottom surface of a track is positioned between a pair of through hole of upper surface of pillow body between be separated out, and between track and road pillow body, add Upper gasket; In the bottom surface draw-in groove of road pillow body, place pad, and the bottom surface through hole of U-bolt from road pillow body gone out to penetrate, the end of U-bolt passes from the upper surface of road pillow body, pressing plate is penetrated the U-bolt end again and pushes down the whippletree place, bottom of I shape track, and fastening nut is fixing to be got final product.
Because road pillow body is to be built by steel concrete to form, normal service life is very long, and the metal parts such as U-bolt are subject to the corrosion of acid colliery water easily in the colliery, after it damages, only need to change corresponding metal parts and get final product, realize real recycling.
According to above-described embodiment, just can realize well the utility model.
