Description

[Detailed Description of the Invention] The present invention relates to a track in a continuous earth and sand transportation device.

Among continuous earth and sand transport equipment, gravity type continuous earth and sand transport equipment is installed on an endless track laid at an angle.
Similarly, transport is carried out by connecting ore cars in an endless manner, loading earth and sand into the ore cars one after another at a high slope position, driving the ore car one after another by its gravity, and discharging the earth and sand from the mine car at a lower position. However, in the case of such equipment, the ore cars are connected in an endless manner without any gaps, so the number of mine cars passing per unit time is far greater than that of ordinary track-type transportation equipment. As a result, the wear life of the raceway is shortened, and the raceway must be replaced frequently.

However, on the endless track, the ore cars are connected without any gaps in the same way, so replacing the track means removing the ore cars on the track and removing them from the track. I had to do it after that. Therefore, the entire transportation equipment will be stopped during that time, which will reduce the operating rate of the equipment and further increase maintenance and repair costs as it will take a lot of man-hours to load and unload the mining cars onto and off the tracks. There was a big problem with connecting.

This invention was developed in consideration of the above-mentioned issues, and it is possible to replace the track without taking the mine car off the track, thereby preventing a decline in operating efficiency and reducing maintenance and repair costs. The purpose is to

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is an endless track, 2a, 2
b, 2c, . . . are ore cars placed on this track 1 in an endless manner without gaps.

The mine cars 2a, 2b, 2c, . . . are connected by a coupler 3. In the figure, L indicates the distance between the wheels of adjacent mining cars in the connection direction.

The above-mentioned track 1 has an inner track and an outer track as one set, and this track 1 has three parts as shown in FIG.
It has been assembled. That is, a first orbit A consisting of a first inner orbit A ₁ and a first outer orbit A ₂ , a second orbit B consisting of a second inner orbit B ₁ and a second outer orbit B ₂ , and a third inner orbit C A _third track C consisting of a third outer track _{C2 and} a third outer track C2 is laid with the same gauge (rail gauge RG). Each set of tracks A, B, and C can be cut at a portion thereof.

That is, as shown in FIGS. 6 and 7, each track A, B, and C has a wheel interval L of the adjacent mining cars
Cuts with smaller length spacing are provided. And between each track end 4, 4 in each cut section, a straight exchange track 5, 5... connecting the track ends of each track and a bent exchange track for track exchange, that is, adjacent first bent exchange tracks 6, 6 connecting the second track B and the third track C;
Second bent exchange tracks 7, 7 connecting the third track C and the first track A located on both sides can be installed interchangeably.

In the above configuration, the mine car 2 is run on the intermediate second track B during normal operation. When this second track B reaches the wear limit, remove this second track B and, for example, the straight exchange tracks 5, 5, etc. laid at the cut part of the outer third track C, and , as shown by the solid line in Fig. 7, the second trajectory B
A first bent exchange track 6, 6 connecting the third track C and the third track C is laid. This exchange track exchange is performed between the wheels L of adjacent mining cars.

When the exchange of the first bent exchange track is completed as described above, the coupler 3 between the mine cars located adjacent to this exchange track part is cut off, and then the drive device which installed the mine car 2 on the ground side (not shown) to proceed. In this way, the first ore car 2 that has been separated is sequentially transferred onto the third track C.

Since the track is laid in an endless manner, all the ore cars 2 on the second track B will be transferred to the third track by making exactly one revolution.
Moved onto orbit C.

In the above state, there is no mine car 2 on the inner track B ₁ of the second track B, so this second inner track B ₁ is replaced.

Next, in order to replace the outer track _B2 of the second track B, the second bent exchange track 7, 7 is connected as shown by the chain line in FIG. The cars 2 are made to make one revolution on the orbit and all the cars are moved onto the first orbit A.

In this state, there is no mine car 2 on the outer track _B2 of the second track B, so the second outer track _B2 is replaced. Thereafter, the second bent exchange tracks 6, 6 for exchanging the second and third tracks are connected from the first track A to the second track B, and the mine car 2 is returned to the second track B.

In addition, in the explanation of the operation in the above embodiment, the second orbit B located in the middle among the three sets of orbits A, B, and C
Although the case where the first track A and C are used as auxiliaries is shown, it is also possible to use the first track A and the first track A until they wear out without replacing them in order until the construction is completed.

Moreover, the objects transported by the mining car 2 are not limited to earth and sand.

In the above embodiment, an example of a gravity-type continuous earth and sand transportation device was explained in which an endless track was laid on a slope, and the gravity-type continuous earth and sand transportation device was moved by utilizing the weight of a mine car loaded with earth and sand. A track is laid on a flat ground, and endlessly connected mining cars are placed on this track.
Of course, this may also be applied to a continuous earth and sand transportation device that is driven on the ground.

The present invention is as described above, and in a continuous earth and sand transportation device in which ore cars 2 connected in an endless manner are mounted on an endless track, a plurality of sets of endless tracks A, B,
C is laid, each set of tracks A, B, and C is provided with a cut section having a length shorter than the wheel spacing between adjacent mining cars 2 in the connecting direction, and each track end at each cut section is 4, 4, there are straight exchange tracks 5, 5... that connect the track ends of each set of tracks, and curved exchange tracks 6, 7 that connect the track ends of different sets.
Because of the configuration in which the ore cars 2 connected in an endless manner are selectively connected, the worn track can be replaced without having to lower the endlessly connected ore cars 2 from the track. It is possible to exchange tracks with the transport device without danger. Additionally, since there is no need to lower the ore car from the track, there is no need for a place to unload and store the ore car. Furthermore, work man-hours (costs) can be significantly reduced. Furthermore, when replacing the track, the device only stops when replacing the replacement track, which prevents a decrease in the operating rate due to the track replacement.
