Description

Conductor rail holding device {HOLDING DEVICE FOR A CONDUCTOR RAIL}

The present invention relates to a holding device for a conductor rail described in the preamble of claim 1 of the Utility Model Registration Claim.

Devices of the type described above are well known in US Pat. No. 4,230,209. The stopper is a box-shaped side member with a slot formed in the longitudinal axis, which is fastened to the sealing of the tunnel by an insulator, and a pin protrudes through the slot. The stopper is used to hold the conductor rail as an overhead line of the rail mount, the conductor rail having a clamp-in contact wire by a groove-contact wire and bolted to the lower end of the pin.

The upper end provided in the box-shaped side member has a wide head as a junction point of the torsion spring, and the lower end supported by the box-shaped side member or the dish-type centring member has a box-shaped side surface. It is inserted into the member. The conductor rail is provided in such a way as to be restored to the stationary box-shaped side member by the spiral spring, and the spiral spring effectively moves the load of the conductor rail.

The high speed portion of the line travels at 240 Km / h and above and it is effective to ensure that the exact distance between the contact wire and the track is as close as possible to the contact force between the electrical collector and the contact wire of the vehicle.

The changeable distance results in a change in contact force and a change in electrical transition resistance, which results in unexpected sparks caused by friction or spark wear and also increases on the current collector and / or contact wire of the vehicle. Brings about. Oscillation of the conductor rails is vibrated and irregularities in the distance between the contact wires and the roadway are compensated by the spring suspension of the conductor rails, which is a known device, very precisely with respect to the height of the top of the roadway. There is a need for a stationary box-shaped side member. In particular, the adjustment of the box-shaped side members requires an outlay since the tunnel seal is not actually oriented oriented exactly parallel to the roadway or actually oriented. Re-regulation of the line presence is very complicated.

DE 195 17 806 A1 discloses a contact wire suspension in a high speed railway that reduces oscillation by a spring restoring vibration element. The spring used in this case is provided so that the spring corresponds to the upward force from the roadway and the force to lift the contact wire.

A holding device similar to the one described above is disclosed in DE 195 48 103 C1, in which the clip holding the contact wire is fastened to a pin which is pre-stressed by a spring and held in stationary motion. It is fastened to the pin fastened to. In this way the spring presses the contact wire downward in the direction of the roadway. EP 0 572 869 B1 (corresponding invention, DE-GM 92 07 518 U1) comprises a support point as a contact line and the contact wire or the contact rail is suspended in the tunnel sealing by means of a spring restoring damping device. In this case the damping device should include an outer steel casing, an inner steel core and an overlapping rubber. The steel core has a continuous bore into which a fastening bolt for holding the holding device is inserted for the contact wire or the conductor rail. The bolt head is supported on the upper surface side of the damping device. The damping device is connected to the cavity tube in a fixed manner. The cavity tube can be fastened to the anchor plate and replaced in a linear manner in the bore and locked by a centrifugal bolt provided intersecting the cavity longitudinal tube so that the longitudinal position of the conductor rail can be set. . The problem in this case is to hold the hollow tube by an intersecting elongated centrifugal bolt. If the centrifugal bolts are loosened slightly, the damping device and the contact wires together with the hollow tube may fall out of the anchor plate. Therefore, delicate and easy longitudinal control is not possible.

It is an object of the present invention to improve the apparatus for holding the above-mentioned conventional conductor rail and at the same time to improve the adjustment for sufficient longitudinal dynamic operation of the conductor rail. According to the present invention, fine adjustment is possible.

The present invention can be achieved by the features described in claim 1 utility model registration claims. And the effects and additional advantages of the present invention are achieved by other dependencies.

The basic construction of the present invention consists of a threaded sleeve having an outer thread and an inner bore provided in the holding plate, and the second sleeve has an inner thread such as a screw nut mounted in a fixed manner as welded to the holding plate. .

The main shaft is provided in the bore in the first sleep so as to be movable and rotated, and the lower free end of the main shaft supports the conductor rail. The upper free end of the main shaft protrudes out of the first sleeve and is supported by a spring of the upper free end face of the sleeve. In this way the conductor rail is provided in a restoring manner by the main shaft and the rail applies the load of the rail to the spring. The vertical position can be finely adjusted by the outer thread of the first sleeve. The longitudinal axis acts as a rotary or pivot joint and the side rails of the conductor rail with respect to the intermediate part of the roadway are possible without difficulty and the holding plate is held at the fastening point like a tunnel wall by a bearer unit having a second joint.

According to another embodiment of the present invention, the first sleeve has a hexagonal outer side wall on an outer thread of the sleeve. In this way the sleeve can be rotated without difficulty by a spanner or other tool to adjust the vertical position.

In another embodiment of the present invention, the rotational position of the first sleeve can be fixed by a retainer having a central recess that engages the hexagonal outer wall of the first sleeve with a positive lock. The recess is preferably provided in a octagonal shape. The retainer was supported by protrusions or bolts on the holding plate to prevent rotation.

According to yet another embodiment of the present invention, a spring restoring suspension is formed by a spring and the spring is supported by a nut supported at the upper free end of the first sleeve and coupled to the upper free end of the longitudinal axis and the spring is a cup spring. It is preferably formed into a stack.

The holding plate is preferably mounted in such a way that it is laterally moved relative to the support structure. In this way the lateral position of the conductor rail can be set during the first adjustment. Since the longitudinal axis acting as a rotary joint can be rotated with respect to the first sleeve, the conductor rails will be outward of the joint with the cut joint of the supporting structure in case of changes in length due to ambient temperature and electric current heating. You can pivot The counterjunction is mounted at the rear end of the support structure between the insulator and the suspension post.

Sufficient current collection can be achieved by the present invention because a uniform degree of restoration is made beyond the length of the conductor rail portion. Since a large amount applies point-wise to the current conductor, each element holding the contact wire and the conductor rail can result in unstable points. Since the pivot head of the conductor rail or contact wire clip is relaxed, not only the vibration but also the "floating" of the current conductor is achieved by a spring. The spring structure is a stack spring structure and has a load load of a current conductor applied to a suspension point. This stack spring is constantly prestressed by the load of the current conductor, which relaxes the spring when the current conductor is raised by the current collector. Since the damping of the spring is reduced, the current conductor can be lifted up and the current collector of the vehicle can be pushed upwards, which results in a reduction in the contact force between the current conductor and the current collector. As a result of fine longitudinal controllability, the contact force can be affected in a high positive manner.

Hereinafter, the most preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings in order to be described in detail that can be easily carried out by those of ordinary skill in the art. . Other objects, features, and operational advantages, including the object, operation, and effect of the present invention, will become more apparent from the description of the preferred embodiment.

Figure 1 shows a front view of the holding device according to the present invention, Figure 2 shows a side view of the holding device as shown in FIG. The holding device 1 for holding the conductor rail 2 holds the groove-contact wire 3, has a cylindrical spindle 4, and the mounting plate 5 at the lower end in a general operating position, such as welding. To be combined. The conductor rail 2 is fastened to the coupling plate 5 by a bolt having a clamping angle 6 and a nut 7. The clamping angle clamps the intersecting axis 8 of the conductor rail between the angle and the mounting plate 5.

The main shaft 4 is provided in the first sleeve 9 so as to move in a linear manner and in a rotational manner. The sleeve 9 has an outer thread 10 which is screwed into the inner thread 11 ′ of the second sleeve 11. The second sleeve 11 is fastened to the holding plate 12 by a fastening method such as welding. The holding plate is fastened by screws 13 to the support structure described in detail in FIG. The upper part of the main shaft 4 protrudes out of the sleeve 9 and directly supports the upper end face of the sleeve or a spring 14 supported by the washer 15. The other end of the spring 14 is supported by the washer 16 by the washer 16 and by the nut 17 which is screwed into the thread 18 at the free end of the spindle. In this case the spring 14 becomes a stack of cup springs. Generally other shapes of springs may be used, for example elliptical springs, elastic sleeves or other forms of springs may be used.

The nut 17 prevents rotation of the main shaft and can be prevented by a bore 19 in which a locking pin is inserted and extending through the main shaft 4 and the nut 17.

The sleeve 9 is adjusted in the vertical position of the holding plate 12 in a stationary state by the rotation of the second sleeve 11, as a result of which the mounting plate 5, the conductor rail 2 and the contact are The vertical position of the wire 3 can be provided in a continuous and delicate manner. In order to fix the rotational position of the sleeve 9, the retainer 20 is provided to be coupled to the upper portion of the sleeve 9, and is located on the upper side of the holding plate 12 and prevents rotation of the bolt 13 in a manner to prevent rotation. Supported.

10 and 13, the sleeve 9 has an outer hexagonal side and the retainer 20 has a central opening in the case of a octagonal shape and the sleeve 9 rotates. Can be locked in a fixed manner. The outer thread 10 of the sleeve 9 thus has a side member which is hexagonal in cross section, ie a side member in which the support thread turn is at each hexagonal point in each case.

Instead of the retainer 20, a locking nut may be provided which is screwed into the outer thread 10 of the spindle 4 and clamped against the upper side of the holding plate 912.

The spring 14 is pre-stressed or loaded by the load of the conductor rail 2 with the contact wire 3 so that the conductor rail 2 is elastically suspended to the spring 14 in a floating manner. It can be lifted by the current collector of the vehicle with the action of the spring 14 in a vertical upward force.

As a result of elastically supporting the load on the conductor rails, improved dynamic operation of the conductor rails is achieved and oscillation induced by the current collector of the vehicle is vibrated in an improved manner and the part of the line is greater than 240 km / h. Can be trebled at a higher speed. Since only the contact force between the current collector and the contact wire or conductor rail can be generated, less spark and improved current transfer are achieved and smaller on the current collector and / or contact wire of the vehicle. By setting the vertical axis, the conductor rail can be adjusted more accurately and the tolerance of the support structure can be compensated more. The vertical axis adjustment can be supported when the conductor rail is supported. Only the washer 20 is lifted and the sleeve 9 is rotated. The retainer washer 920 is then allowed to fall to the holding plate 912 and is blocked between the bolts 13.

The main shaft 4 can also be rotated about the longitudinal axis of the sleeve 9. It is possible to design the support structure of the conductor rail to pivot in this way, and it is possible to design the conductor rail to pivot laterally to be practical for maintenance and repair. It can also be intercepted by this method of spreading between the conductor rails.
