Abstract
The utility model discloses a structure for preventing a crane track from loosing. The utility model is formed by that a connecting bolt is fixed on a crane beam made of reinforced concrete; the connecting bolt is connected with a steel shim plate on which a fixing piece of the crane track is fixed; the crane track which is arranged on the steel shim plate is fixed with the steel shim plate into a whole through the fixing piece of the crane track. The utility model can ensure the control of the height mark of the track top of the crane track on one hand, and solve the problems that when the track is subjected to the function of horizontal force, the pressure the pressing plate of the fixing piece of the track is bore by the steel shim plate, and is diffused into shim layers; the shim layers only plays the function of adjusting the height mark. The structure of the utility model has clear routes force transmission, simple construction and safe performance, avoiding the serious result that the connection of the whole track is ineffective due to the partial failure of the shim layers. The utility model the advantages of high safety performance and stable operation.
Description
Technical field:
The utility model relates to a kind of structure that prevents that crane runway is loosening, belongs to rail mounted crane runway technique for fixing field.
Background technology:
At present, the existing longitudinal movement along factory building of sports equipment of the prior art such as crane also has by its dolly along horizontal the moving of factory building.Particularly in the nonferrous metallurgy industry, as the electrolysis multilift, its above characteristics are obvious especially.These cranes have on the one hand that tonnage function big, operation is many, the characteristics of dolly Heavy Weight, have the characteristic of hard hook block car on the other hand simultaneously.When its dolly cross motion, the horizontal force that acts on track and crane girder is bigger, and is high for the anti-loosening requirement of track.And in the prior art, adopting traditional track connecting mode to be on the ferro-concrete crane girder: concrete secondary screed-coat Thickness Design requires to be controlled between 30 ~ 50 (mm) according to standard drawing between with track and crane girder, but because post bracket top mark height and crane girder height unavoidably can produce error in the construction of reality, the stack of the two error, may make above-mentioned control data out of reach in the construction of reality, the situation of 10 ~ 15mm in practice of construction, often occur having only.When above-mentioned control data is less than normal, be difficult to guarantee the density of secondary screed-coat, can not reach the requirement of full-page proof in the standard drawing.And pressing plate in the crane runway connecting element and secondary screed-coat area of contact only are 30 * 90 (mm2), and the pressing plate end is apart from the screed-coat edge only about 23mm.The QU100 track selected for use of electrolysis multilift routine particularly, the general track of its orbit altitude wants high, and the distance of crane horizontal force action point at the bottom of the track is bigger, and the side direction bending moment of generation is also relatively large.This part bending moment passes to crane girder by pressing plate, and the pressing plate end is because very big local pressure appears in the rotation trend of track at this moment, and very big pressure is born in secondary screed-coat part, is often damaged by pressure.After the secondary screed-coat under the pressing plate end destroyed, the whole rail joint piece was just ineffective, and this moment, track was moved under bigger horizontal force action, had a strong impact on the normal operation of crane, also bigger accident might take place.Therefore the existing mode that connects track on the ferro-concrete crane girder can not guarantee that track satisfies the requirement of crane safe operation.
Summary of the invention:
The purpose of this utility model is: provide a kind of structure that crane runway is loosening that prevents that can guarantee the crane safe and reliable operation, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises the crane runway (1) that is located on the ferro-concrete crane girder (6), on ferro-concrete crane girder (6), be fixed with tie bolt (2), on tie bolt (2), be connected with billet (4), be fixed with crane runway connecting element (7) on billet (4), crane runway (1) is placed on that billet (4) is gone up and pressing plate and billet (4) by crane runway connecting element (7) are fixed as one; Between billet (4) and ferro-concrete crane girder (6), be provided with the bed course (5) of adjusting orbit altitude.
Owing to adopted technique scheme, the utility model can guarantee on the one hand the control of crane runway tread absolute altitude, and when having solved track on the other hand and being subjected to horizontal force action, the pressure of fixture of the rail pressing plate is born by billet, and be diffused in the bed course, bed course only works to adjust absolute altitude.Horizontal force is passed to billet by the track joint piece, and billet is coupled as one by bolt and ferro-concrete crane girder, and the vertical, horizontal horizontal force is reached on the ferro-concrete crane.Structure power transmission route of the present utility model is clear, and construction is simple, the performance insurance.Avoided because the local failure of bed course causes whole rail to connect the serious consequence that lost efficacy.Therefore, the utility model compared with prior art the utlity model has the advantage of safety performance height, working stability.
Description of drawings:
Accompanying drawing 1 is a planar structure scheme drawing of the present utility model;
Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;
Accompanying drawing 3 is the B-B cross-sectional schematic of accompanying drawing 1.
The specific embodiment:
Embodiment of the present utility model: the crane runway (1) that is located on the ferro-concrete crane girder (6) can directly adopt crane runway of the prior art, the fixing respectively tie bolt (2) of going up on ferro-concrete crane girder (6), tie bolt (2) can adopt common C grade standard bolt, billet (4) is fastened on the tie bolt (2) by nut and spring washer (3), between billet (4) and ferro-concrete crane girder (6), make the bed course (5) that one deck is adjusted orbit altitude with high strength contraction-free grouting concrete pouring then, and the absolute altitude of levelling track, after treating that the grouting material reaches prescribed strength, go up by the fixing crane runway connecting element (7) of going up of the method for welding at billet (4), crane runway connecting element (7) can adopt TG50 standard mount or general crane runway connecting element series of products in " 00G514 (six) ", then crane runway (1) is placed on that billet (4) is gone up and the pressing plate by crane runway connecting element (7) is fixed as one itself and billet (4).
Claims (2)
1. structure that prevents that crane runway is loosening, it comprises the crane runway (1) that is located on the ferro-concrete crane girder (6), it is characterized in that: on ferro-concrete crane girder (6), be fixed with tie bolt (2), on tie bolt (2), be connected with billet (4), be fixed with crane runway connecting element (7) on billet (4), crane runway (1) is placed on that billet (4) is gone up and pressing plate and billet (4) by crane runway connecting element (7) are fixed as one.
2. the structure that prevents that crane runway is loosening according to claim 1 is characterized in that: be provided with the bed course (5) of adjusting orbit altitude between billet (4) and ferro-concrete crane girder (6).
