The numbers in the figure respectively indicate that 1-a bracket main body, 2-wheels, 3-wheel driving motors, 4-a stool storage cavity, 5-a first support column, 6-a second support column, 7-a folding stool, 8-a wheel shaft, 9-a support column and 10-a driving shaft sleeve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution:

as shown in fig. 1-2, an anti-skid electric flat car frame running on a subway steel rail comprises a bracket main body 1, wheels 2, a wheel driving motor 3, a stool storage cavity 4 and a folding stool 7,

a flat plate for supporting personnel and materials is arranged on the upper surface of the support main body 1, and wheels 2 for running on subway steel rails are arranged below the support main body 1;

the wheel driving motor 3 is arranged between the wheels 2 and used for driving the wheels 2;

the stool storage cavity 4 is arranged below the bracket main body 1;

the folding stool 7 is folded and stored in the stool storage cavity 4.

In one embodiment, the wheels 2 are installed in two groups, which are respectively installed at the front and the rear of the bracket body 1, a wheel shaft 8 is arranged between the two wheels 2 at the front of the bracket body 1, a driving bushing 10 is arranged between the two wheels 2 at the rear of the bracket body 1, and the bracket body 1 is fixed on the wheel shaft 8 and the driving bushing 10 through a supporting column 9.

A driving shaft connected with the wheel driving motor 3 is arranged in the driving shaft sleeve 10, and the driving shaft drives the two wheels 2 at the rear part of the support main body 1 so as to drive the whole vehicle frame to run.

In one embodiment, a first pillar 5 is installed below the folding stool 7, the upper end of the first pillar 5 is hinged with the bottom of the folding stool 7, the lower end of the first pillar 5 is hinged with the bottom of the stool storage chamber 4, and a second pillar 6 is hinged in the middle of the first pillar 5.
