Description

The invention relates to the field of transport engineering, in particular to rail transport and installation equipment, and in particular to the structures of stands.

The invention can be used for assembling / assembling and moving large-sized units on a movable platform along a rail track to the assembly unit of the test bench.

State of the art in the field of the claimed invention.

Known rail undercarriage support stand, containing wheel pairs on shafts, a rectangular frame (see the description to the patent of the Russian Federation No. 2392201, IPC B64G 1/64, B64F 5/00, 2010).

The closest to the claimed object of the invention of the same purpose and general in technical essence, the achieved result and in terms of the totality of features is a transport platform moving along rail guides, containing a base made in the form of a rectangular frame, with load-bearing wheelsets mounted on the edges, fixed on the axles passing through the base (see description for RF patent No. 2582527, IPC В61В 3/00, В61В 13/00, B65G 63/02, taken as a prototype).

The disadvantage of the described devices is the impossibility of accurate positioning of the unit relative to the elements of the assembly unit of the stand due to the absence of means of spatial regulation of the unit in their composition, which complicates the process of docking and installation of the unit as a whole.

The technical result to be achieved by the claimed invention is the creation of a structure that provides accurate positioning of the unit to the mounting unit of the stand, and, as a consequence, simplifies the assembly / installation process.

The specified technical result is achieved by the fact that the transport and installation platform contains a base made in the form of a rectangular frame, with bearing wheelsets installed along the edges with flanges preventing lateral displacement, elements for fixing the unit relative to the platform, elements for fixing the platform at the place of use.

New in the invention is that the base contains a flat mechanism made in the form of a rocker arm, forming a rotational pair with the central axis of the base and having a non-rigid connection with the frame, with one wheelset movably mounted on the rocker arm, and the second wheelset movably mounted on the frame, at the ends of the axle of each wheel pair, a device for adjusting the platform in the vertical and transverse directions relative to the wheels is installed, rigidly fixed on the base and containing a housing with an axle box installed in it with a rolling bearing and a sliding sleeve covering the end of the axle of the wheel pair and allowing it to move relative to the axle box when using a power screw with an emphasis on the end face of the axle of the wheelset, installed in the axle box body, which has a guide that allows the axle box to move relative to the body of the platform control device by means of a power screw with an emphasis on the axle box body installed in the body of the control device pl atforms.

The use of a rocker arm in the platform design makes it possible to achieve a stable position of the platform on the rail track during movement and installation, and the platform control device in the vertical and transverse directions allows achieving accurate positioning of the installed unit relative to the test bench.

The transport and installation platform contains a base 1 (Figs. 1, 2), made in the form of a rectangular frame 2 (Figs. 1, 2), with load-bearing wheelsets 3 (Figs. 1, 2, 4) installed along the edges with flanges 4 ( Fig. 2, 4), preventing lateral displacement. The platform also contains fixing elements 5 (Fig. 1, 2) of the unit relative to the platform, fixation elements 6 (Fig. 1, 2) of the platform at the place of use.

The base 1 (Fig. 1, 2) contains a flat mechanism made in the form of a rocker arm 7 (Fig. 1, 2, 3), forming a rotational pair with a central axis 8 (Fig. 3) of the base 1 (Fig. 1, 2).

The rocker arm 7 (Fig. 1, 2, 3) has a non-rigid connection with the frame 2 (Fig. 1, 2). In this case, one wheel pair 3 (Fig. 1, 2, 4) is movably mounted on the rocker arm 7 (Fig. 1, 2, 3), and the second wheel pair 3 (Fig. 1, 2, 4) is movably mounted on the frame 2 ( Fig. 1, 2).

At the ends of the axle 9 (Fig. 2, 5, 4) of each wheel pair 3 (Fig. 1, 2, 4) there is a device 10 (Fig. 4) for adjusting the platform in the vertical and transverse directions.

The device 10 (Fig. 4) for regulating the platform is rigidly fixed on the base 1 (Figs. 1, 2) and contains a housing 11 (Fig. 4) with an axle box 12 (Figs. 5, 4) installed in it with a rolling bearing 13 (Figs. 5, 4) and sliding sleeve 14 (Fig. 5, 4).

The sliding sleeve 14 (Fig. 5, 4) covers the end of the axle 9 (Fig. 2, 5, 4) and allows the movement of the axle 9 (Fig. 2, 5, 4) of the wheelset 3 (Fig. 1, 2, 4) relative to the axle box 12 (Fig. 5, 4) with the help of the power screw 15 (Fig. 5, 4), abutting against the end face of the axle 9 (Fig. 2, 5, 4) of the wheelset 3 (Fig. 1, 2, 4). The power screw 15 (Fig. 5, 4) is installed in the housing 16 (Fig. 5, 4) of the axle box 12 (Fig. 5, 4).

The axle box 12 (Fig. 5, 4) has a guide 17 (Fig. 5), which allows its movement relative to the housing 11 (Fig. 4) of the device 10 (Fig. 4) for regulating the platform by means of a power screw 18 (Fig. 4), abutting against the body 16 (Fig. 5, 4) axlebox 12 (Fig. 5, 4). The power screw 18 (Fig. 4) is installed in the housing 11 (Fig. 4) of the device 10 (Fig. 4) for regulating the platform.

The device works as follows.

The transport and installation platform is installed on the rail track. In a place accessible for the operation of the lifting device by means of fixing elements 5 (Figs. 1, 2), the unit is mounted on the base 1 (Figs. 1, 2) of the platform.

The platform with the unit located on it moves along the track to the assembly unit of the stand.

In the area of unevenness of the track, due to the rotation of the rocker arm 7 (Fig. 1, 2, 3) on the central axis 8 (Fig. 3) relative to the frame 2 (Fig. 1, 2), a constant stable support of the platform on all four wheels is provided, which contributes to more even distribution of the load between the wheels and eliminates the unstable position of the unit. In this case, the rocker arm 7 (Fig. 1, 2, 3) has a non-rigid connection with the frame 2 (Fig. 1, 2).

The ribs 4 (Fig. 2, 4) of the wheel pairs 9 (Fig. 2, 5, 4) prevent the lateral displacement of the platform.

At the place of application, the unit is positioned relative to the assembly unit, after which the platform is fixed to the foundation by means of elements 6 (Figs. 1, 2).

The positioning of the unit relative to the mounting unit is carried out by means of devices 10 (Fig. 4) for adjusting the platform in the vertical and transverse directions, installed at the ends of each axle 9 (Figs. 2, 5, 4) of wheel sets 3 (Figs. 1, 2, 4).

The control device 10 (Fig. 4) is rigidly fixed on the base 1 (Fig. 1, 2) of the platform and contains a housing 11 (Fig. 4) with an axle box 12 (Fig. 5, 4) installed in it with a rolling bearing 13 (Fig. 4). 5, 4) and sliding sleeve 14 (Fig. 5, 4).

The sliding sleeve 14 (Fig. 5, 4) covers the end of the axle 9 (Fig. 2, 5, 4) of the wheel pair 3 (Fig. 1, 2, 4) and allows its movement relative to the axle box 12 (Fig. 5, 4) ...

The platform is adjusted in the transverse direction by turning the power screw 15 (Figs. 5, 4) and converting the rotary motion into translational motion. The end of the power screw 15 (Fig. 5, 4), resting on the axle 9 (Fig. 2, 5, 4) of the wheelset 3 (Fig. 1, 2, 4), moves the axle box 12 (Fig. 5, 4) to the required provisions.

The axle box 12 (Fig. 5, 4) has a guide 17 (Fig. 5), allowing the movement of the axle box 12 (Fig. 5, 4) relative to the body 11 (Fig. 4) of the platform control device 10 (Fig. 4) by turning the power screw 18 (Fig. 4) and converting rotary motion into translational motion. The end of the power screw 18 (Fig. 4) installed in the housing 11 (Fig. 4) of the platform control device 10 (Fig. 4), abutting against the housing 16 (Fig. 5, 4) of the axlebox 12 (Fig. 5, 4), moves the axle box 12 (Fig. 5, 4) to the required position.

After positioning, the unit is connected to the assembly unit of the stand.

Dismantling is carried out in the reverse order. The use of the proposed technical solution makes it possible to create a transport and installation platform that is simple in design and reliable in operation, which has the ability to accurately position the unit of a relative test bench.

An additional advantage from the use of the proposed invention is the stable movement of the transport platform along the track.
