Description

The invention relates to railway transport, in particular, to mobile technical means used when working on a contact network of electrified railways.

The aim of the invention is to expand the work area.

Figure 1 shows a general view of the proposed vehicle for work; contact network in the folded (transport) position; Fig. 2 schematically shows a possible variant of the working arrangement of the mounting platforms and the rotary device, top view.

The vehicle (Fig. 1) consists of a control cabin 1 mounted on the main frame 2 supported on wheel pairs 3. A removable or stationary working body is also mounted on the frame, consisting of a rotary device 4, at the end of which a telescopic lift 5 is rigidly fixed with rotatable (relative to the vertical axis of the elevator 5) mounting platforms 6 and 7 with a drive and the possibility of their fixation in a predetermined position. The rotator has the possibility of circular rotation by means of a drive 8 on it, for example, an electromechanical one. In this case, the device 4 is supported on the rotation unit 9 and the additional support wheel 4 is supported on the rotation node 9 and the additional support wheel 10, which has a trajectory in the form of a circle 11 during rotation (FIG. 2). The support 12 of the contact network and mechanical clamps are also conventionally depicted 13 for opportunities

temporary local tension, for example, contact suspension. In order to stabilize the elevator 5, which is deployed in its working position, the platforms 6 and 7 are provided with mechanical grippers 14, which allow rigidly to embrace standing reinforced concrete supports.

In the case of winch lifting, it is advisable to bring one of the platforms 6 or 7 to the adjacent support 12 and attach it to it with the help of the grip 14, which increases the stability of the system and allows the winch to lift more heavy loads. The conical shape of the upper part of the support allows when the grip 14 is closed, provide the necessary hard contact between the mounting platform and the support. In order to provide convenience (and, as a result, increase in labor productivity) when working on an installed reinforced concrete support, it may be expedient to attach the site to the support by means of a catch located on the side of the site. For this purpose, the grippers 14 are made removable with the possibility of installation along its sides, the gripper 14 may have an electric lock into the control circuit of the movement of the vehicle in order to prevent it from moving when personnel erroneously act when the gripper is fixed to the support.

To replace, for example, a damaged retainer (insulator), especially on curved sections of lines where temporary tension of the contact suspension is required, the work is carried out as follows. The swivel device 4 turns to contact one of the clips 13c with the contact wire out of its dimension (in plan), after which the wire is firmly fixed by this clip. The swivel device turns in the right direction (in this case, in the direction of the axis of the path), pulling it behind it contact wire. At the required place, the turn is stopped and the lift 5 is fixedly fixed. The damaged retainer (insulator) is replaced, after which, turning in the opposite direction, the device 4 relieves tension and the clamp 13 releases the wire. Some other operations are similarly performed.

work on the contact network, requiring temporary local tension.

Thus, the claimed vehicle has:

- the possibility of movement along the axis

railway track by wheel pairs;

-the possibility of circular rotation and fixation in the desired position of the assembly

device rotation about a vertical axis intersecting with the longitudinal axis of symmetry of the vehicle and the rail track;

- the possibility of circular rotation and fixation in a certain position of the actual installation sites around the vertical axis of the lifting device;

- the possibility of a rigid connection between the installation sites and standing reinforced concrete

supports to increase the stability of the entire vehicle in the unfolded position;

- the possibility of temporary local tension, for example, contact suspension

or a flexible cross member, necessary for carrying out some work on the contact network.

The use of a vehicle can facilitate checking the verticality of the installation of reinforced concrete supports relative to the vertical bar of the lifting device.

The use of the proposed design will allow in practice to significantly increase labor productivity during work on the contact network, side lines of communication, automatic blocking, etc.

Claims (1)

Invention Form Vehicle for Work on a contact network containing a main frame supported on the wheel pairs and a telescopic lift associated with it with two mounting platforms fixed at different levels with the possibility rotation relative to the telescopic elevator, characterized in that, in order to expand the working area, it is provided with a beam with an axis of rotation relative to the main frame at one end thereof, At its other end, a rigid body is rigidly fixed, the beam is placed parallel to the main frame, and the mounting platforms are provided with grippers.  J   9 " Schig.2
