Becoming the framework main body 1 that the present invention is bent upwards apparatus main body is to be combined by triangular truss, the one end stretches out the distortion quadrilateral structure that forms to the upper right side of Fig. 1, in the part that is positioned near the rail end of this framework main body 1, form supporting device by cranse support 4 and spheric seat 5, will be by this spheric seat 5 in order to the cranse 2,2 of controlling rail ' hang.Because cranse 2,2 ' can load and unload and be installed on the support 4 freely and usefulness spheric seat 5 supports, so freely swing on left and right directions that it can be in Fig. 1 and the direction perpendicular to the paper of Fig. 1.And as shown in Figure 2, cranse 2,2 ' can abut against rail's end portion rightly at the assigned position place of rail.By clamp with clamping component 11 cranses 2,2 ' the bottom, cranse 2,2 ' reliably can be fastened on rail's end portion.With cranse support 4, spheric seat 5 and cranse 2,2 ' formation traction and fixation portion.
In the rail pressurization part that is set to the mechanical function point of this device on the position of the rail pars intermedia direction of this traction and fixation portion certain distance, said device is added to compressive force on the rail by support 7 and spheric seat 6.And on the top ends of stretching out of the framework main body 1 of the rail pars intermedia side more farther, the support 8 with concavity inner face is set than this rail pressurization part distance.The shape of the recess of this support 8 as shown in Figure 1, the cross section of seeing from the front of framework main body 1 is arc, is rectangle from the cross section that perpendicular direction is seen.That is to say, identical with the shape of cutting off this resulting cross section of cylinder in place along the side near cylinder sides.With these support 8 support hydraulic cylinder portions 10.
There is hydraulic cylinder shell in hydraulic cylinder portion 10, and cantilever beams portion is arranged on the top of this hydraulic cylinder shell 10, the protuberance that stretches out to the below that the recess with support 8 engages be arranged on this cantilever beams portion below.This protuberance matches with the shape of above-mentioned recess, and this concave depth of its aspect ratio is bigger.Hydraulic cylinder portion 10 can load and unload and be installed in freely on the support 8.
And, hydraulic cylinder and be arranged on the inside of this hydraulic cylinder portion 10 along the piston that this hydraulic cylinder inner face slides, oil pressure is supplied with this piston by the outside, so piston promptly moves to the direction near framework main body 1 upward.Cranse 3,3 ' be installed in from piston and stretch on the bar of below.By clamp with clamping component 12 these cranses 3,3 ' the bottom, can be with cranse 3,3 ' be fastened on rail's end portion.Drag the bottom with support 8, hydraulic cylinder portion 10 and cranse 3,3 ' formation main body.
At this moment, get the distance of traction between fulcrum, promptly to drag the distance between the bottom be one meter for rail pressurization part and framework, and then to drag the ratio of the distance between the rail pressurization part of distance relative traction and fixation portion between the bottom and intermediate compression fulcrum be 1: 3 for rail pressurization part and framework.As a result, be bent upwards 22 tons of the traction load less thaies that needed framework drags the bottom, can make this device do very compact small and exquisitely for making 50N rail (being the rail of 50kg/m).
About 50 centimeters of this height of devices, about 50 kilograms of body weight.Framework main body 1 is that preferably the steel that are suitable for welding of 10～16mm are made with wall thickness 4～20mm.
In addition for this device can be bent upwards rail local arbitrarily, traction and fixation portion takes with cranse 2,2 ' the catch mode of rail's end portion, usually in order vertically to pressurize to the rail head end face, the rail pressurization part that becomes the compression fulcrum is pressurizeed by support 7 by being installed in the spheric seat 6 on the apparatus main body.
And then for making this device be convenient to move, also be provided with its wheel 13,13 of supporting ', the time take to lift framework main body 1 in operation and make wheel float off the mode of rail with above-mentioned support 7.
In above-mentioned traction and fixation portion and since be by constituting by spheric seat 5 and cranse support 4 supporting device supporting cranse 2,2 ', so even cranse 2,2 ' slightly variant two cranses that also can make of length bear impartial load.
This device of above-mentioned this spline structure is installed near the rail that takes place the end of rail that rail joint sinks, by the cranse 2,2 of traction and fixation portion ' control rail's end portion both sides inside and outside between the rail of end of rail and fixing, drag the cranse 3,3 of bottom ' control rail's end portion both sides inside and outside between the rail of rail pars intermedia and fixing with clamping component 12 by main body with clamping component 11.Then drag hydraulic cylinder supply oil pressure and framework main body 1 is drop-down to the rail side in the hydraulic cylinder portion 10 of bottom to this main body.At this moment traction and fixation portion becomes the fulcrum on the mechanics, and the rail pressurization part becomes application point, and main body is draged the bottom becomes the force, with lever principle the rail compressive force is added to the rail pressurization part.Thereby the position in the rail pressurization part can easily make end of rail be bent upwards.
For the rail main body is bent upwards, in any case between itself and apparatus main body, apply tractive force to two ends, supporting-point adds compressive force therebetween, will be bent upwards in this position.Because heal greatly in the position that this is bent upwards, more close the end of rail then bending of rail, be necessary to make and reduce as far as possible near the tractive force of rail end and the interval of compressive force.
In the present embodiment hydraulic cylinder is installed in main body and drags the bottom, drag the directly fixing top of stretching out of rail and framework main body 1, bottom, should consider and to be arranged on the rail pressurization part in order to the jack etc. that the power of rail and framework main body 1 is drawn back in generation by this main body.Yet the compressive force of aforementioned its rail pressurization part of this situation is compared with the situation of present embodiment and is about 2～6 times, and this is unsafty.
In the present embodiment, as the traction and fixation portion of framework main body one end as fulcrum, near the part of the support 7 of this point supporting framework main body as application point, point-to-area being positioned at across this application point, apart from the framework top ends of application point certain distance as the force, utilize power that the lever principle hydraulic jack adds to the force with between fulcrum-application point between distance and fulcrum-force the ratio of distance double, this power that has doubled is added to application point.The practical value of this ratio preferably 2～7: 1.
At this moment in order to catch rail and, between the jack installation portion of apparatus main body and rail, to leave suitable space to lower traction equipment.For reality is implemented this apparatus main body, and make it the weight minimum, will cooperate with spandrel frame stable on mechanics, use the apparatus main body that is made of distortion quadrangle skeleton as the jack installation portion, said distortion quadrangle skeleton is that an end of framework is stretched out to the upper right side.
With this device end of rail is bent upwards from the mechanics angle, compression fulcrum place at the traction fulcrum and the pars intermedia of end of rail side, the device with rail between do not have relative displacement, and at the traction fulcrum of the rail central portion side that must add motility, along with the device end is drawn downwards, the relative rail of apparatus main body just has corresponding gradient.
Therefore, in order also at an easy rate tractive force to be added on the rail in heeling condition, the main body that hydraulic cylinder is housed is draged the bottom, owing to support with barrel surface, thereby framework main body 1 is swung to the left and right directions of Fig. 1 freely relatively, and owing to the top ends of hanging, thereby loading and unloading easily in the framework main body.
When realizing this device, can to transmit reliably in order exerting all one's strength and to make the sheet material that constitutes framework main body 1 that certain thickness be arranged, by changing the width of framework bar part, and can only support loading with sheet material.At this moment power can very reasonably be transmitted, thereby can make it lightweight.
Because the present invention constitutes as described above, so can obtain following effect.
Because make the traction fulcrum of end of rail side as much as possible little, so can make being bent upwards of the big end of rail of curvature nearby with the spacing of compression fulcrum.
Because the traction fulcrum of traction fulcrum that rail is distolateral and rail central portion side is enough big with respect to the ratio of the distance between the compression fulcrum, therefore just can make the end of rail bending with very little power.
Because be, with certain thickness sheet material constituent apparatus main body, so device can be done very light based on spandrel frame stable on the mechanics.
Because except that the rail pressurization part of centre, all be with spheric seat supporting traction fulcrum, so the framework main body is vertically stably fixing with respect to the rail installed surface when the rail end is bent upwards.The cranse that drags the bottom by main body can often vertically and stably be added to rail with tractive force.
Because it is the structure that can swing in barrel surface that main body is draged the end of bottom, and be suspension type, so can be implemented on the mechanics rationally, device loading and unloading on rail can be guaranteed safety during operation rapidly.
