Background

In recent years, with the rapid development of intelligent technology, the system development and application technology of the mine underground unmanned electric locomotive is widely popularized. From the application practice, it can be seen that accurate positioning has important significance for reliable operation of the unmanned electric locomotive. Due to the severe environment conditions of high humidity and much dust in the underground, in order to realize the precise positioning and stopping technology of the locomotive, besides the application of the photoelectric sensing device, a rotary counter of a mechanical device is usually configured to improve the positioning reliability.

Because the unmanned electric locomotive in operation has the characteristic of large inertia due to the self-weight, the phenomenon that wheels are locked and do not rotate any more but still slide on a track can usually occur when the unmanned electric locomotive is braked, so that the accurate positioning parking effect is influenced. That is, the running distance of the vehicle cannot be accurately obtained by counting the number of revolutions of the wheels of the locomotive. Therefore, it is generally adopted that a driven wheel is fixedly mounted on the vehicle body, and the driven wheel is not restricted by braking, so long as the driven wheel is kept in contact with the rail, the counting can be accurately performed. In practical applications, however, due to the complex operating conditions encountered, such completely fixed conventional constructions encounter situations,

(1) the driven wheel is not in real contact with the guide rail, and the phenomenon of slipping exists. Because the driven wheel is fixed at the side plate of the electric locomotive, the driven wheel is connected with the side plate of the electric locomotive, the field guide rail is uneven, and the driven wheel can be suspended temporarily in the running process of the electric locomotive.

(2) When a curve turns, the driven wheel is often suspended outside the track due to the action of a straight contact formed between the front wheel and the rear wheel of the locomotive body, and the driven wheel and the track cannot normally contact with each other.

(3) The auxiliary rail limiting the running track of the locomotive wheels is arranged at a bend and an ore unloading station, and forms different height differences with the top surface of the rail, so that the auxiliary rail can interfere with the end surface of a roller of a driven wheel, and the driven wheel mechanism is damaged.

Due to the situation, the fixed driven wheel mechanism is difficult to normally play, and the abundance and the application effect of the locomotive accurate positioning technical means are seriously limited.

Detailed Description

Embodiment 1, as shown in fig. 1-fig. 2, the utility model provides an unmanned electric locomotive walking counting assembly, including locomotive body 1, one side of locomotive body 1 is equipped with height-adjustable's connecting seat, and the fixed mount 3 that is provided with of lower extreme of connecting seat, the lower extreme left and right sides of mount 3 are equipped with bearing body 4 respectively, and it has gyro wheel 5 to articulate between two bearing body 4, and gyro wheel 5 is the ellipsoid-shaped structure and one end that extend about the major axis level and is connected with belt pulley 8, and the top of belt pulley 8 is equipped with rotary counter 10, and rotary counter 10 sets up on mount 3 and realizes the transmission through drive belt 9 and belt pulley 8.

The lower side surface of the roller 5 is sequentially abutted with the rail 7 and the secondary rail 6 from the center to the outer side, so that the roller 5 is always in contact with the rail 7 and the secondary rail 6 in the process of rolling along the rail 7.

Wherein, the connecting seat includes tensioning spring 2, locating support 11, locating lever 12 and adjusting nut 13, locating support 11 is totally two and respectively one on one side of locomotive body 1, locating lever 12 runs through two locating support 11 and has nested tensioning spring 2 on the part below locating support 11 of below, tensioning spring 2's lower extreme supports to have solid fixed ring and upper end to support and lean on the lower terminal surface at locating support 11 of below, gu fixed ring fixes on locating lever 12, threaded nest has adjusting nut 13 on the part that locating lever 12 stretches out locating support 11 of the top, adjusting nut 13's lower extreme supports to support and leans on the up end at locating support 11 of the top, the lower extreme of locating lever 12 is fixed to be set up on mount 3.

And a vertical surface 121 is arranged on the side surface of the part of the positioning rod 12 below the middle part between the two positioning supports 11, a parallel vertical surface 111 is arranged on the through hole of the positioning support 11 at the lowest part corresponding to the vertical surface 121, and the vertical surface 121 and the parallel vertical surface 111 are attached together, so that the positioning rod 12 cannot rotate relative to the positioning supports 11.

After the whole connection of the device is finished, the positioning support 11 and the locomotive body are fixedly connected through bolts, and the positioning rod 12 is connected with the positioning support 11 through the tensioning spring 2 and the adjusting nut 13. Thus, when adjusting the adjusting nut 13, the positioning rod 12 can only ascend or descend without axial rotation due to the limitation of the positioning groove on the positioning support 11 at the lowest position, and the whole counting device is adjusted to be at a proper height position just by the ascending and descending action of the positioning rod 12.

The fixing frame 3 is used for connecting the roller 5, the bearing body 4, the rotary counter 10 and the like into a functional main body and connecting the functional main body with the positioning rod 12, so that a complete framework of the walking counting device of the unmanned electric locomotive is formed.

When the locomotive runs normally, the roller 5 is contacted with the track 7 to roll, the belt pulley 8 connected with the roller rotates along with the rolling, the rotary counter 10 is driven to work through the belt, and counting information is transmitted to an automatic control system of the locomotive running through signals.

When the vehicle is turning in a curve, the driven wheel assembly, which is located between the front and rear wheels, is moved away from the track 7 by the action of the straight line of the front and rear wheels, where the secondary rail 6, which prevents the wheels from derailing, is often provided. Therefore, on one hand, the oval roller 5 can compensate the distance change in the length direction, and the effective contact with the track 7 is ensured; on the other hand, even if the height difference is generated between the auxiliary rail 6 and the rail 7, the oval roller 5 can still smoothly go up the auxiliary rail 6, and the side surface jamming phenomenon between the auxiliary rail 6 and the rail cannot occur.

When the locomotive arrives at the unloading station, the whole walking counting device can be lifted along with the lifting of the locomotive body due to the position limiting effect of the positioning rod 12, and the abnormal touch phenomenon with the outside cannot occur.
