Abstract

The invention discloses a tractor for magnetic levitation traffic installation routing inspection rescue. The tractor is composed of a bearing driving wheel (1), a loading driving wheel (6), a bogie (2), a tractor body (3), a power transmission system (4) and a driving braking system (5). The bearing driving wheel (1) walks on a sliding face (a1) of a rail F (A). The loading driving wheel (6) additionally walks inside a groove-shaped face (a2) opposite to the sliding face (a1) of the rail F (A), so that the friction area of the wheels and the positive pressure of the upper and lower wheels are increased, the frictional force is effectively improved, large traction is obtained, meanwhile, the interior of the groove-shaped face of the reverse face of the rail F is not affected by rain or snow or freeze weather, and it is better ensured that the larger traction is obtained.

Example Embodiment

[0020] Example one:

[0021] Such as figure 1 , figure 2 , image 3 , The tractor is running on the rail row composed of F rail (A) aluminum induction plate (B) and sleeper (C) on the maglev track line;

[0022] The towing vehicle runs on the sliding surface (a1) of the F rail (A) by carrying the driving wheels (1), and then supports the car body (3) through the bogie (2), and the power transmission system (3) is installed on the car body (3). 4) and driving brake system (5);

[0023] A loading driving wheel (6) connected to the bogie (2) is added to the groove-shaped surface (a2) formed by the two magnetic pole legs under the F rail (A), which is the opposite side, and the loading is realized by the hydraulic cylinder (8) to increase The friction area and positive pressure of the wheels are generally not affected in the groove-shaped surface on the reverse side of the F rail in rain, snow, and freezing weather, so it can still provide a stable and large traction;

[0024] The moment formed by loading the load driving wheel (1) and the load driving wheel (6) shall not affect the safety of the bolts connecting the F rail (A) and the sleeper (C) (the picture does not indicate the link bolt);

[0025] The power is driven by the internal combustion engine generator and the hydraulic motor of the hydraulic station. The hydraulic motor is directly installed in each drive unit (not detailed in the figure). It can also be powered by a rechargeable battery or directly installed with an on-board current receiver to be driven by electricity;

[0026] Couplers (not shown in the figure) are set on the front and rear of the tractor to link external vehicles, and the testing equipment can also be directly installed on the tractor;

[0027] The tractor is equipped with two front and rear bogies, and two front and rear guide wheels (7) are arranged on the outside of each bogie. The guide wheels (7) are controlled by the outer side (outside of the braking surface) (a3) of the F rail (A) to achieve guidance ;

[0028] The guide wheels (7) are arranged in groups, each guide wheel group is composed of two front and rear guide wheels (7) with the same line center offset, and the distance between the axles is greater than the link seam of the F rail (A);

[0029] The guide wheel (7) can have a gap control with the guide surface (a3), or it can act elastically on the outer side (outside of the brake surface) (a3) of the F rail (A), and its elastic force guides the bogie (2) in the line In the center position, guide deviation correction.

Example Embodiment

[0030] Embodiment two:

[0031] The first embodiment is usually used when a large traction force is to be obtained, such as pulling a heavy object, climbing a slope, etc., when the tractor is required to drive fast and does not require a large traction force, unlike the first embodiment, the driving wheel (6) is loaded It is separated from the F rail (A) surface, and the guide wheels are also guided by gap control or elastic guide.

[0032] It can be seen from the figure and the above installation steps that the tractor for patrol and rescue of maglev transportation installation of the present invention can provide a reliable and large traction effect.

[0033] All the features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and/or steps, can be combined in any manner.
