Description
technical field:
The utility model relates to a kind of steel rail pre-bending device that the tracks such as light rail, heavy rail carry out pre-bending that is applicable to, particularly be a kind of simple and easy pre-bending device of rail that is applicable to carry out under building site, field non-transformer and severe environmental conditions rail all directions and different size track.
background technology:
At present, the mounting method that pressure steel pipe of hydropower station installation adopts track to coordinate transport trolley to draw substantially, carries out track according to penstock general arrangement situation during still general penstock rail transport and buries underground.Now, there will be warp rail, the arc track of arc track as reclinate in level and buckling.And in Hydropower Station Construction, purchase more modern bending machine or jim crow and certainly will increase engineering cost input, be unfavorable for reducing construction investment, bending machine and jim crow need construction power supply and require the restrictions such as operating environment in addition, do not possess penstock quick, the severe construction requirement of construction environment are installed, and the installation of penstock conveying track must launch in advance, otherwise construction in later period cannot be carried out.
utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, provide a kind of and can meet track installation needs, can also effectively reduce labour intensity simultaneously, effectively improve the conevying efficiency of penstock, also to reach instructions for use to the required radian of track pre-bending simultaneously, solve the problem of penstock conveying track all directions, different size curved in tracks, reach that penstock track is steady, the simple and easy pre-bending device of the rail of safe and reliable requirement.
The purpose of this utility model is achieved like this:
The simple and easy pre-bending device of the utility model rail, the two ends of work type beam are contained in respectively in first load clamp lower end work type beam the first draw-in groove and second load clamp lower end work type beam the second draw-in groove, on the first load clamp and the second load clamp upper end opposite position, have respectively and the rail draw-in groove for the treatment of that pre-bending rail coordinates, jackscrew is positioned between the first load clamp, the second load clamp and is placed on work type beam.
The track two ends of with first, second load clamp, need being carried out to pre-bending during the utility model work are locked, the work type beam of usining is installed jackscrew as bearing capacity face, screw pair transmission by manual operation jack, to reach jack top, raise the head and hoist, raising the head and act on rail contact surface in top, obtains the effect that rising of required radian reaches pre-bending.
The utility model device has substituted the equipment such as bending machine or jim crow needs construction power supply or gadget supporting place placement to require harsh operating environment; Be specially adapted to carry out under building site, field non-transformer and severe environmental conditions the crooked pre-bending construction operation of rail all directions and different size track, this device reduces labour intensity, increases work efficiency, improves track construction difficulty, can by the required pre-bending of field working conditions, go out the orbital planes such as horizontal curve, longitudinal radian, operating environment requires simple.The utility model installation weight is little, and cost of manufacture is low, fills, tears open flexible, reusable, simple to operate, safe and reliable.
Press market Inquiry: rail bender purchase cost approximately: 6.38 ten thousand yuan/platform, approximately 2.1 ten thousand yuan of costs of transportation, installation and adjustment operating cost is about 1.2 ten thousand yuan.Total needs ten thousand yuan of input cost 6.38+2.1+1.2=9.68.The utility model device cost of manufacture is about 0.8 ten thousand yuan of left and right, by contrast, cost-saving being about: 8.88 ten thousand yuan, and install reusable.The buckling problem that has solved penstock conveying track each side, different size track, reaches steady, the safe and reliable requirement of penstock track.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is load clamp structure schematic diagram.
Fig. 4 is work type structural representation.
the specific embodiment:
Referring to Fig. 1～Fig. 4, the simple and easy pre-bending device of the present embodiment rail, the two ends of work type beam 1 are contained in respectively in i beam first draw-in groove 3 and second load clamp 4 lower end work type beam the second draw-in grooves 5 of the first load clamp 2 lower ends.On the first load clamp and the second load clamp upper end opposite position, have respectively and the rail draw-in groove 7 for the treatment of that pre-bending rail 6 coordinates.Jackscrew 8 is positioned between first, second load clamp and is placed on work type beam.Rail pre-bending direction changes, and the shape of rail draw-in groove is wanted corresponding adjustment.In Fig. 1, F, H are respectively rail pre-bending direction, pre-bending sagitta.
In the present embodiment, load clamp can adopt steel plate cutting to make, and arranges rail draw-in groove and work type beam draw-in groove, fixes and is connected rail and work type beam, is main load parts.Work type beam: adopt steel plate cutting, welding production, the reverse power transmission supporting rail of support helix jack, makes rail surrender pre-bending, is critical piece.Jackscrew: buy finished product, model is by the yield strength meter of pre-bending rail, is main stressed, force transferring part, and the sagitta of the effective adjustment of displacement rail pre-bending radian by screw pair transmission (lever plug) reaches the effect of pre-bending track; The core component of this device.
The simple and easy pre-bending device of the utility model rail is installed, disassembly procedure is as follows:
(1) making of simple and easy pre-bending device: utilize steel plate to process two cover load clamps and a set of work type beam by Fig. 3, Fig. 4, load clamp cutting of steel rail clip groove, by the cutting of instructions for use direction, after cutting polishes flat draw-in groove; Work type beam is welded by frange plate 9 and strength plate 10 as shown in Figure 4.In welding process, to control the deflection after frange plate welding deformation, be convenient to work type beam and load clamp and install.
(2) installation of simple and easy pre-bending device (Fig. 3, Fig. 4):
First first, second load clamp is installed on to two sections, work type beam, then utilizes cushion block 11 that two sections, work type beam is leveled up whole, guarantee that load clamp can normally slide at load clamp activity interval, then by locked on the rail draw-in groove of two load clamps of rail insertion; Jackscrew is positioned over to work type beam top flange plate plane place, and by the auxiliary driving (lever plug) of manpower rotational screw jack, jack pushes up the sagitta of effective adjustment of displacement rail pre-bending radian of raising the head, and reaches the effect of pre-bending track.
(3) dismounting of simple and easy pre-bending device: device integral body is padded with cushion block 11, first by work type beam, the work type beam draw-in groove by load clamp slowly takes out, then monolithic load clamp is taken out along the rail surface slip of pre-bending moulding, this device can recycle after preserving.
