Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to one arm shaft of one arm shaft to be connected to a ground guard for signal security equipment (hereinafter, simply referred to as ground guard) fixed above a sleeper in a railway. The present invention relates to a mounting member for a ground signal for railway signal security equipment, which is capable of avoiding an undesired expansion of the ground element setting space by allowing the end portion to face downward near the side edge in the longitudinal direction of the ground element.

[Conventional technology]

As a means for attaching the ground element, which is fixed above the sleepers in the railway, to the rail, there is a demand for miniaturization of the ground element 2 by setting a pair of arm shafts 1 and 1 at positions indicated by chain lines in FIG. 7, for example. Although satisfied, it is difficult to set the arm shafts 1 and 1 to the alternate long and short dash line positions because the distance between the sleepers 3 and 3 and the attachment position to the ground element 2 or the position to pull out the ground element lead wire and various other members are required. Also, the magnetic field generated by a magnetic material such as an iron component on the arm shafts 1, 1 and the like becomes an obstacle to the coupling with the train side car top passing above the ground element 2, and this coupling is reduced. Therefore, it becomes difficult for the train side to quickly and surely grasp the signal status of the ground element 2. Therefore, as one of the measures to prevent the reduction of the coupling due to the magnetic material,
In FIG. 7, it has been proposed to set the arm axis at the 5,5 position. In the figure, 6 is a trough, 7 is a lead wire, and 8 is a gravel stop.

[Problems to be solved by the device]

Although the reduction of the coupling between the ground element 2 and the vehicle upper element due to the magnetic material can be avoided by setting the arm shaft to the 5,5 position in the above-mentioned prior art section, the setting space is reduced by downsizing the ground element 2 itself. It is difficult to satisfy both the narrowing of the armature and the generous arrangement of various members other than the ground element 2. In the end, either the chain line of the pair of arm shafts 1,1 or the setting to the 5,5 position is either on the ground. There is a problem in that it is difficult to avoid the disadvantages of the attachment means of the child 2.

The present invention was proposed by focusing on the above-mentioned problems, and the purpose thereof is to satisfy the demand for downsizing of the ground element, while the connection between the ground element and the train side car upper element is connected. It is an object of the present invention to provide a mounting bracket for a ground signal for railway signal security equipment that is not reduced by the magnetic field of a magnetic material such as an arm shaft.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the mounting brackets of the ground signal for railway signal security equipment according to the present invention are provided with an inner and outer award set on the left side of the sleeper and an inner and outer award set on the right side. The left and right arm shafts are screwed and penetrated into each of the above, and the ground conductors for the railway signal security equipment are attached to the first and second non-magnetic support plates fixed to the respective ends of these arm shafts. The mounting bracket of one of the arm shafts has one end faced downward near the side edge parallel to the long axis of the ground element, and the lower part of the mounting shaft is penetrated and fixed to this end. One end of the first backing plate is penetrated and fixed upward, and the other end of the first backing plate is fixed to the inside of the ground element by a mounting bolt. The other arm shaft has an end portion orthogonal to the side edge. The lower end of the mounting shaft is penetrated and fixed to this end, and one end of the second receiving plate is penetrated and fixed above the mounting shaft. The other end of the second backing plate is fixed to the inside of the ground element with a mounting bolt, the first backing plate is set orthogonally to the long axis, and the second backing plate is parallel to the long axis. It is set.

[Action and effect]

In this invention, of the pair of arm shafts having one end fixed to the ground element, one end of one arm shaft is made to face downward near the side edge along the long axis of the ground element, and the lower end is penetrated and fixed to this end. One end of the non-magnetic first receiving plate is penetrated and set above the mounting shaft, and the other end of the first receiving plate is fixed to the inside of the ground element with a mounting bolt. By setting it perpendicular to the long axis of the child, and by setting the second non-magnetic support plate fixed above the other arm axis parallel to the long axis, the ground child is expanded to an unnecessary extent. However, it is possible to prevent the coupling between the ground element and the train-side car upper element from being reduced by the magnetic field generated from the magnetic substance such as the arm shaft. Compared with the above, it is possible to avoid expanding the setting space of the ground element, and to reduce the coupling due to the magnetic field. Rapid and reliable command from the ground element at all times, can be granted to the train side of the car upper child Te.
