In order to achieve the purpose, the utility model discloses an RGV trolley track, which comprises a main track and a plurality of sections of auxiliary tracks arranged in parallel, wherein each section of auxiliary track is connected with the main track into a whole through a connecting block, and a grid structure is formed between the main track and the auxiliary track;

a plurality of first rail accessories and a plurality of second rail accessories are installed on the surface of the main rail respectively, the top surfaces of the auxiliary rail, the first rail accessories and the second rail accessories are flushed to form a rail car running plane, the rail car is provided with walking wheels, and the difference between the outer diameters of the flanges and the outer diameters of the walking surfaces of the walking wheels is equal to two times of the height difference between the auxiliary rail and the connecting block.

Preferably, the connection blocks are installed at both sides of the main rail for supporting and connecting the sub rail.

Preferably, the first rail attachment and the second rail attachment are each fixed to the main rail by a screw.

Preferably, the running surface of the primary rail and the running surface of the secondary rail are flush with each other.

Compared with the prior art, the utility model discloses a RGV dolly track has following beneficial effect:

the scheme simplifies the structure of the matched rail car, lightens the weight of the rail car and reduces the running fault risk of the matched rail car; the installation is convenient, the maintenance is easy, and the working efficiency of the rail car is greatly improved.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 6 to 8, an embodiment of the present invention discloses an RGV trolley track, which includes a main track 1 and a plurality of sections of auxiliary tracks 2 arranged in parallel, each section of the auxiliary tracks 2 is connected with the main track 1 into a whole through a connecting block 3, the connecting blocks 3 are installed on two sides of the main track 1 for supporting and connecting the auxiliary tracks 2, a grid structure is formed between the main track 1 and the auxiliary tracks 2, and the auxiliary tracks 2 and the main track 1 are fixed and assembled together through the fixing effect of the connecting blocks 3.

A plurality of first rail accessories 4 and a plurality of second rail accessories 5 are installed on the surface of the main rail 1 respectively, the first rail accessories 4 and the second rail accessories 5 are fixed on the main rail 1 through screws, the walking surface of the main rail 1 and the walking surface of the auxiliary rail 2 are flush with each other, and the rail car can walk stably.

Through the whole fixed track of above-mentioned mode, the stable use of whole track of being convenient for, simultaneously because it adopts assembled structure, when the in-service use, some structures take place wearing and tearing can carry out the local change of dismantling, need not demolish the change completely, more convenient and fast.

Set up walking wheel 6 on the railcar, the difference of the flange external diameter of walking wheel 6 and walking face external diameter equals the twice of height drop between accessory track 2 and connecting block 3, because height drop equals the flange external diameter of walking wheel 6 and half of the difference of walking face external diameter between accessory track 2 and connecting block 3, when walking wheel 6 walks on the track, walking wheel 6 is when through main track 1 and accessory track 2 hookup location and break away from the contact with the track face, make the flange excircle of walking wheel 6 all the time with connecting block 3 surface contact, thereby make walking wheel 6 remain steadily throughout at the in-process of walking, improve the stability that the vehicle travel.

Specifically, suppose that the height drop between the secondary track 2 and the connecting block 3 is h, and the flange external diameter and the walking face external diameter of walking wheel 6 are poor to be d, make h equal to d/2, then when the railcar moves on the track, through main track 1 and secondary track 2 butt joint department, when connecting block 3's position department promptly, walking wheel 6 has not detached with the track walking face yet, the flange excircle of walking wheel 6 has contacted with connecting block 3, and when the flange excircle of railcar walking wheel 6 is about to detach from connecting block 3, walking wheel 6 contacts with the track walking face in advance again, support the railcar and walk on the track, thereby make the railcar can even running.

Similarly, the top surfaces of the auxiliary track 2, the first track accessory 4 and the second track accessory 5 are flush, so that the walking wheels 6 are more stable when walking on the auxiliary track 2, the walking wheels are not prone to shaking, and the walking wheels can still be stable when passing through the joints between the tracks.

For traditional dolly track, this scheme has effectively solved the railcar and has had the problem of safe risk in the operation on the track, effectively prevents that the condition of derailing or unstable from appearing in the dolly on the track.

The scheme not only simplifies the structure of the matched rail car, but also lightens the weight of the rail car; and the running fault risk of the matched rail car is reduced, and the device is convenient to install and easy to maintain.

The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
