Description

IN-TRAFFIC VEHICLE

The utility model relates to mapping and may be

used in the automation of work (for example, flaw detection) in pipes with a cross-section of various configurations made of various materials, both seamless and with internal seams, longitudinal, spiral, transverse, on flat sections, vertical and with bends in various planes, ducts and closed volumes of various devices.

Known in-vehicle vehicle used to move cleaning tools in pipelines and containing a running gear, a housing and a control system (see description to AS USSR No. 820927, BOSH 9/04, 1979 L /). A disadvantage of the known means is its low maneuverability and design complexity.

Known in-tube vehicle containing several propulsors and means for pressing them against the moving surface, made in the form of power cylinders (see the description to the AS of the USSR No. I7I0430, V62D 57/02, 1989 / 2/) .. A disadvantage of the known device is slotted construction, bulkiness and low speed of movement.

Closest to the claimed in its technical essence is the well-known in-line vehicle containing several propulsors made in the form of wheels or tracks and means for pressing them against the moving surface, made in the form of spring-loaded supports. (see the description of the patent of France No. 2662989, V62D 57/028, 1990/3 /).

A disadvantage of the known device is its bulkiness and design complexity, which limits the scope of its application, for example, for pipelines of small cross-section (20-50 mm).

The inventive utility model is aimed at simplifying the design.

The specified result is achieved by the fact that the in-tube vehicle contains several movers and a means of pressing them against the displacement surface, made in the form of a coil spring placed between the movers.

A distinctive feature of the claimed in-line vehicle is the implementation of the means for pressing the propulsors to the displacement surface in the form of a rolled rod placed between them.

The implementation of the means of pressing the propulsion to the displacement surface in the form of a coil spring simplifies the design of the device, because due to its structural properties, the spring provides the transfer of constant force to several propulsors at once, regardless of their movement relative to each other in a certain range. In addition, the spring provides a sufficiently high force with small dimensions and weight, which makes it possible to produce small-sized in-tube vehicles capable of moving through pipes of small diameter (20-50 mm)

The essence of the claimed utility model is illustrated by the presented graphic materials.

Figure 1 schematically shows an embodiment of an in-line vehicle designed to move along boxes (pipes) of rectangular cross section, while in Fig. Ka) a side view is shown, and in Fig. 1 (6) is a front view. Fig. 2 shows an embodiment of an in-tube vehicle for moving round or oval cross-sections through pipes. Figure 2 (a) shows a front view, and figure 2 (b) the device is depicted in a perspective view.

The in-tube vehicle contains several propulsors made, for example, in the form of wheeled carts I (or tracks, as in .. e), with two or four wheels 2, which are equipped with a corresponding drive 3, made, for example, in the form of an electric motor installed either on the axis connecting the wheels, or directly on one of the wheels.

Between the propulsors there was placed a self-twisting coil spring 4 of constant pressure, which was connected to them using an articulated frame 5 containing hinges 6.

The device operates as follows. Due to the force of the spring 4, the vehicle located outside the pipe is in a position with the motors as far apart as possible, therefore, to place it in the pipe, it is necessary to apply some force to overcome the spring resistance and bring the engines closer

I at a distance equal to the cross section of the pipe. As a result of compression of the spring 4, the propellers will be pressed to the displacement surface with a constant force, which is transmitted from the spring through the hinge frame 5 with hinges 6. On command from the control panel (not shown in the drawings), the 3 wheel drive 2 is turned on and the vehicle starts to move.

Due to the pressing of the propulsors against the walls of the pipe, their good adhesion to the displacement surface is provided, which allows them to move along pipes located not only horizontally, but also vertically.

To increase the carrying capacity without reducing maneuverability, the vehicle may be constructed with a straight link consisting of several sections shown in FIG. I and 2, connected by appropriate couplers.
