the single-side track wheels are sleeved on the key grooves at the two ends of the main shaft and fixedly connected with the main shaft through flat keys, each single-side track wheel comprises a large wheel and a small wheel, the small wheels are used for pressing the top surface of the track, the large wheels are used for limiting the small wheels on the track, the outer peripheral surface of each small wheel comprises a cylindrical surface and two conical surfaces, the two conical surfaces are connected to the two ends of the cylindrical surface, and the section diameters of the two conical surfaces are gradually reduced from the middle to the two sides.

Preferably, a bearing is installed between the main shaft and the main shaft connecting part.

Preferably, a plurality of parallel rollers are mounted on the top of the vehicle body, and two ends of each roller are rotatably connected with the vehicle body.

Preferably, along the arrangement direction of the rollers, a pin shaft detachably connected is mounted in the middle of two ends of the top of the vehicle body, and the pin shaft extends upwards from the top surfaces of the rollers.

Preferably, in the moving direction of the unilateral rail wheel, the two ends of the vehicle body are provided with handles for pushing and pulling the vehicle body.

On the basis of the common knowledge in the field, the above preferred conditions can be combined at will to obtain the preferred embodiments of the present invention.

The utility model discloses an actively advance the effect and lie in: only the cylindrical surface in the unilateral rail wheel is contacted with the rail, thereby reducing the frictional resistance between the rail car and the rail and reducing the abrasion of the rail surface.

Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

Fig. 1-2 show an unpowered rail car comprising: vehicle body 100, main axle 200, and a plurality of single-sided rail wheels 300. The vehicle body 100 has a main shaft coupling part 110 at a bottom thereof, and a main shaft 200 passes through the main shaft coupling part 110 and is rotatably coupled to the main shaft coupling part 110. The spindle 200 has key slots 210 at both ends, and the single-side rail wheel 300 is sleeved on the key slots 210 at both ends of the spindle 200 and fixedly connected with the spindle 200 through a flat key (not shown in the figure). As shown in fig. 3, the unilateral rail wheel 300 includes a large wheel 310 and a small wheel 320, the small wheel 320 is used for pressing the top surface of the rail 800, the large wheel 310 is used for limiting the small wheel 320 on the rail 800, the outer circumferential surface of the small wheel 320 includes a cylindrical surface 321 and two tapered surfaces 322, the two tapered surfaces 322 are connected to two ends of the cylindrical surface 321, and the cross-sectional diameters of the two tapered surfaces 322 gradually decrease from the middle to two sides.

In the scheme, the structural design of the outer peripheral surface of the small wheel 320 can avoid the contact between the outer peripheral surface of the whole small wheel 320 and the track surface, and the contact area between the outer peripheral surface and the track surface is reduced, so that the friction resistance is reduced, and the abrasion of the track surface is reduced. As the small wheel 320 of the single-side rail wheel 300 is worn, the area of the cylindrical surface 321 is increased, and the area of the conical surfaces on both sides is decreased.

In order to reduce rotational frictional resistance between the main shaft 200 and the main shaft connecting part 110, a bearing 400 is installed between the main shaft 200 and the main shaft connecting part 110.

In practical application, the unpowered railcar truck is mainly used for transporting heavier objects, so that the difficulty in moving the railcar up and down is high, and in order to solve the problem, in the scheme, a plurality of parallel rollers 500 are mounted at the top of the railcar body 100, and two ends of the rollers 500 are rotatably connected with the railcar body 100. On the production line, the assembly line platform butted with the unpowered rail car is also provided with rollers 500 or a conveyor belt and the like, so that the parallel rollers 500 can be used for horizontally moving objects, the up-and-down transportation is avoided, and the labor intensity is reduced.

In order to prevent the objects from sliding off the rollers 500 during the movement of the unpowered rail car, the pins 600 are detachably connected to the middle of the two ends of the top of the car body 100 along the arrangement direction of the rollers 500, and the pins 600 extend upward from the top surfaces of the rollers 500. The pin 600 mainly serves as a stopper, i.e., the pin 600 is removed when transferring objects, and the pin 600 is mounted during movement.

In addition, both ends of the vehicle body 100 have grips 700 for pushing and pulling the vehicle body 100 in the moving direction of the one-sided rail wheel 300.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
