Abstract

DEVICE FOR WELDING AND CONTINUOUS LAYING OF LONG-DIMENSIONAL fia: I - .-. OBJECTS containing a platform mounted on the chassis on which a welding mechanism is installed, characterized in that in order to increase productivity, it is provided with support rollers mounted along the form plate and parallel pressing rollers arranged above them, which are mounted behind the mechanism for welding along the platform movement the latter is mounted on the chassis with the possibility of rotation in the horizontal and vertical planes.

Description

eleven

The invention relates to transportation, primarily for the welding and laying of rails and pipes.

A device for welding and continuous laying of lengthy objects is known, which comprises a platform mounted on the chassis, on which the welding mechanism is installed -1 j.

A disadvantage of the known device, characterized by the ability to provide its chassis with the ability to move over rough terrain while bearing on it an extended body of high flexural rigidity, is the limited ability to center and extend this extended body on the platform due to the absence of special guides.

The purpose of the invention is to increase productivity.

The goal is achieved by the device for welding and continuous laying of lengthy objects, mainly rails, containing a platform mounted on the chassis, on which the welding mechanism is installed, equipped with supporting rollers mounted along the platform and parallel pressing rollers arranged above them, which are mounted behind the welding mechanism along the movement of the platform, the latter being mounted on the chassis with the possibility of rotation in the horizontal and vertical planes.

FIG. 1 shows a device for welding and continuous laying of long objects, a general view; in fig. 2 shows a section A-A in FIG.

The device includes a turntable 2 placed on the running chassis 1, which is provided with a rear set of support 3 and a front set of 4 guide rollers with transversely placed axes 5 arranged parallel to the plane of the platform. The rear set of support rollers 3 is provided with a set of crimping rollers 6 arranged above it, the axes 7 of which are connected to the axes of the support rollers 3 by means of 8 links.

The platform is equipped with hydraulic cylinders 9 and 10 for its fixation in the off position. The cylinders 9 and tO are hinged to the swivel base 11 mounted in the running chassis 1, and their rods are pivotally connected to the platform 2, to ensure that the angle of inclination of the platform 2 relative to the running chassis 1 is connected by the hinge 12 to the swivel base 11.

The device works as follows.

After the vehicle is delivered to the location 5 of the installation of a lengthy object on

its platform 2 is successively centering and then attaching (e.g., welding using resistance welding machine 13) new sections 14 and lowering the long-length object 15 formed onto the subgrade while the chassis is being towed 16.

25 After touching the lengthy object 15 with its free end of the ground, the hydraulic cylinders 9 and 10 are placed in a floating position and the platform

2 adopts a fixed inclined 30 at an angle oi position to the level of the horizon under the influence of the elastic forces of a long object, the working end of which is clamped between sets of supporting

3 crimping 6 rollers. Specified

The compressed position does not change and, therefore, the angle practically does not change either (L tilts the platform to the horizon even if the running chassis 1 moves through the transverse folds

40 terrain, as the platform rotates, pressed by the extended body around the hinge 12. At the same time, the stability of the platform 2 is lost on the running chassis and sliding

45 of the working end of the extended body from the welding zone is prevented by the presence of crimping rollers b.

Thus, the presence of rollers makes it possible to center 50 and build up a long-legged object on a device for welding and continuous laying of long objects.
