Description

  The present invention relates to a positioner for a switch adjuster that can complete all operations with a minimum of personnel to newly install or replace a switch adjuster.

  Generally, a railway track has a branch line separated from a main line, and a so-called branching device is provided at an intersection of the branch line with the main line. This branching unit is provided with a switch adjuster that smoothly performs conversion. The switch adjuster is a device that plays the role of adjusting the stroke of the rolling mill to the stroke of the Tongrel and pressing the Tongrel against the basic rail with a constant pressure (referred to as close contact).

  By the way, the switch adjuster is required to operate precisely in order to push the Tongler to the basic rail with a constant pressure, and in the inspection of the track, the degree of adhesion of the Tongrel is periodically measured. If a problem such as insufficient force for pressing the Tongler is confirmed in the measurement of the degree of adhesion, it is necessary to replace the switch adjuster in use with a new one.

  Normally, this replacement operation is performed according to the following procedure. That is, as shown in FIG. 5, the arm bracket 31 of the switch adjuster is loosened with the bolt 33 and the nut 34 that are fixed to the rolling bar 32 that is connected to the tongrel (not shown), and the arm 33 is pulled out by pulling out the bolt 33. Pull 31 away from the rolling bar 32 and remove the switch adjuster. In order to mount the switch adjuster, the arm of the new switch adjuster is applied to the lower side of the rolling bar 32, and the bolt 33 is passed through the arm bracket and the rolling bar 32 so that the screw of the bolt 33 is passed through the rolling bar 32. The procedure is such that the nut 34 faces the upper surface, and the nut 34 is screwed into the screw of the bolt 33 and tightened.

  By the way, in order to attach a new switch adjuster to the rolling bar 32 by the above-described replacement work, one worker supports the switch adjuster from the bottom and another worker supports the bolt hole of the arm bracket and the rolling bar. Positioning so as to match the 32 bolt holes, passing the bolts 33 through the respective bolt holes, and then screwing and tightening the nuts 34 is an operation involving two persons at the same time. Normally, the switch adjuster is a heavy device, which puts a considerable burden on the workers who support the full weight.

  As a method of reducing the burden on such workers, it is conceivable to use a platform or rest of an appropriate height that supports the switch adjuster, but the height from the track surface to the rolling bar is the same as that of the turnout structure. It is not constant due to differences and the like, and the height of the platform must be adjusted each time the replacement work is performed, which takes time.

  The work performed simultaneously by two persons often wastes time, and if possible, the work with the minimum number of people is preferable. In addition, such work is often performed at night when the vehicle is stopped, and work by a minimum number of people is preferable in order to suppress high costs due to overtime work.

  An object of the present invention is to provide a positioning device for a switch adjuster capable of completing all the operations with a minimum number of people to newly install or replace the switch adjuster.

  The positioning device for a switch adjuster according to the present invention is a positioning device for a switch adjuster that positions an arm bracket at a predetermined position of the rolling rod prior to fixing the arm bracket to the rolling rod by a fastening member provided from the arm bracket to the rolling rod.
