Description

The invention relates to the field of operation of electrified railways and can be used in the design of contact suspensions of electrified railways.

An analogue of the flexible clamp of contact wires from a steel bar was the clamp of the contact wire of the contact network, patent application number of the Russian Federation 2003109390, publication date 20.11.2004.

On curved sections of the track (on the outside), to fix the position of the contact wire in the plan, flexible clamps are used - "guardrails" made of stranded copper or bimetallic wire (usually 4-7 cores). Due to the high wear of the conductors, breaks of the "guardrails" take place, which leads to the exit of the contact wires beyond the size of the current collector, followed by the break of the latter.

The design of a flexible clamp of contact wires from a steel bar in the form of a rod with a cross section of 10 mm (Fig. 1.), consists of an unregulated part [1], an adjustable part [2], fastening and adjusting fittings, a clip with an eyelet [3] (KS-040 ), a two-footed eyelet [4] (KS-013), flexible strip clamps [5] for one or two contact wires and prevents damage to electric locomotive current collectors in units with a flexible clamp.

The non-adjustable part [1] is rigidly attached to the strip clamps through the fixing ring [6] of the non-adjustable part on one side and inserted into the eye of the KS-040 clamp [3] by the fixing ring [7] of the non-adjustable part on the other side (Fig. 2.). The seams of the rings [8] are arc welded.

The non-adjustable part [1] can be of two types: 1 - in the form of a bar with two fixing rings at the ends; 2 - in the form of a ring with a diameter of 70 mm, fastening the strip clamps and a clip with an eyelet (KS-040) [3].

The adjustable part [2] is an adjusting rod with a locking ring on one side [9] and a safety hook on the other side [10]. The fixing ring [9] is connected to the two-fingered eyelet [11] (KS-013). The seam of the ring is welded [8] by arc welding. The safety hook [10] 10 mm long is bent at an angle of 100 ° and serves as a protection against slipping of the clip with the eyelet (KS-040) [3]. The main purpose of the safety hook [10] is to engage it with blocks when adjusting the structure. An angle of 100 ° is used for secure engagement of the blocks, preventing them from slipping.

Suggested sizes for manufacturing:

Pros:

• reliability;

• ease and speed of adjustment of the zigzag contact wire;

• quickness of installation and replacement;

• the presence of a safety hook.

The complete assembly is shown as in FIG. 3.
