Abstract
The end face that contacts with each other of a pair of rail is connected, compress jointly, do the pressurization welding of rail, the clamping operation is divided into mutually independently perpendicular positioning clamping and lateral register clamping.Face timing when contact jaw, earlier the head soffit of two rail ends is upwards lifted, make the soffit of the upper surface of two rails, determine the preconditioning reference altitude against level gauge.Use a pair of clamping device at rail web sandwich rail end then.At this moment, against a clamping device of rail web one side, with stronger power, rail web is shifted onto on the preset reference position, another clamping device pushes the side in addition of rail web round about with more weak power.
Description
When the relevant end face with a pair of rail of the present invention is done the pressurization welding,, and carry out the used chucking device of this method with the method for rail by correct relative position relation clamping.
On a pair of rail end face with pressure bonding access the connection status of joint, if any laterally offset appears in joint, or the connection status that changes or the like of the straightening of the height of the upper surface of joint and joint, can influence the ride comfort sense of rail vehicle greatly, operation stability, peak of noise or the like, the especially rail joint of the hot-short operation accuracy of having relatively high expectations.This shortcoming of rail joint, be because railway itself has the problem of the accuracy of manufacture, or there is the rail clip before the pressurization welding to decide precision problem, so rail to be connect must be eliminated the accuracy of manufacture problem of rail, by the correct relative relation, correctly join end to end, especially before welding, eliminate the bending change of rail.
This type before a pair of rail pressure bonding with the method and apparatus of rail clamping, one for example 56-136292 number this patent that discloses of Japanese patent laid-open publication gazette awarded people and the application's case with.But, because this traditional clamp method and equipment, use a system, with single hydraulic cylinder group, pass through linkage, the folder of a pair of rail being made simultaneously vertical direction and side direction is fixed, decide in the process at folder, after rail being done the adjusting of opposing vertical position and lateral position, the adjusting operation of necessary control shaft cylinder group, especially lateral position requires the operator to climb to below the press welder, replacing is fixed by bolts to a pair of folder on the clamping device, or pad is done the adjusting of lateral position between insert regulating.Because determining the action need of straightening between this operation and two rails repeats repeatedly, usually need about ten minutes more than owing to correctly folder is fixed in a straight line with two rails, again because pressurization welding subsequently itself only needs a few minutes, so disadvantage is the time of almost all handling, and has all consumed on the position adjustments of rail.
One object of the present invention is the clamp method equipment that proposes a kind of rail, and purpose of design is to overcome the above-mentioned defective that has earlier in the skill field, particularly can simply promptly carry out the calibrating operation of the vertical relatively and lateral position of a pair of rail.
According to the present invention, why above-mentioned purpose can obtain, and is the clamping with each track, is divided into mutually independently perpendicular positioning clamping and two steps of lateral register clamping.
Particularly, according to an aspect of the inventive method, when two contact jaws are faced timing, two rail ends are at first located in vertical plane, the soffit of two rail head portions to pop-up, is made the soffit of the upper surface of rail head against level gauge, and level gauge provides the reference levels of pre-straightening.Use the both sides of a pair of clamping device clamping rail web on two rail ends then, method of clamping is in two clamping devices, one side of contact rail web, rail web is shifted onto on the reference position of pre-alignment with stronger power, the opposite side of another clamping device contact rail web uses more weak power to the rail web reinforcing in the opposite direction.
The alignment in vertical direction of the method according to this invention, rail can done before the clamping, and the reference altitude by each the level gauge soffit that is adjusted in each rail end is determined reaches requirement alignment precision.And, before doing clamping, regulate by the reference position that the stroke end of the clamping device on each rail end is determined, just can similarly be adjusted to permissible accuracy to the side direction alignment of track.
Be used for realizing that the equipment of the inventive method has a pair of chuck, in order to a pair of rail of clamping, the contact end face of rail is relative, two chucks corresponding to rail vertically on, only can to a direction mutually near or transport out of.Each chuck has a level gauge that the position is adjustable, determine reference altitude in the vertical direction with its soffit, hydraulic means is used to contact rail head both sides soffit, rail is upwards lifted, first clamping device is used for the side against the rail soffit of girder, rail web is shifted onto the stroke end of pre-straightening, just on the reference position, second clamping device is used for the side in addition against rail web, with more weak power rail web is pushed to first clamping device.Preferably make the soffit of level gauge,, can do some slips, thereby make rail can do a spot of side direction activity with respect to rail with the part that contacts the rail head soffit of hydraulic means, and do not cause hydraulic means on the power of lifting significantly decrease.On the other hand, the front end of first and second clamping device still can clamp rail web and not let alone to slide in the centre.In a kind of desirable form, each clamping device has a hydraulic cylinder group and is installed in clamping plate on the hydraulic cylinder group piston rod front end.The hydraulic cylinder group of first clamping device has position, adjustable stroke end, and for accomplishing the concrete arrangement of this point, for example, making the hydraulic cylinder group is the fixed journey system length type, thereby the position can be regulated.
