Embodiment one:
as shown in fig. 1 to 8, an anti-running car limiting device is mounted on a track running car device. The track traveling trolley 10 is a track trolley for tensioning a coal mine belt conveyor, and adopts a traction steel wire rope 11 for traction to tension a belt 12. The track-moving carriage 10 moves over a track 30, the track 30 being a railroad rail. In this embodiment, the rear end is the end where the track traveling trolley is pulled in the working state, and the traction wire rope 11 pulls the track traveling trolley 10 at the rear end, so as to realize tensioning of the belt.
The rail at the rear side of the rail traveling trolley 10 is provided with an anti-running limiter 20, and two rails are respectively provided with an anti-running limiter 20. The anti-running limiter is provided with the anti-running clamping block 21, the anti-running clamping block 21 is embedded into the web groove 31 of the track 30, and a moving gap C1 is reserved between the anti-running clamping block 21 and the web of the track 30, so that the anti-running clamping block 21 (and the anti-running limiter 20) can move along the track 30, and the anti-running limiter 20 can be kept to be erected on the track. The anti-running fixture block 21 and the upper side face of the track web groove are provided with a dumping interval C2, the dumping interval C2 enables the anti-running limiter 20 to generate dumping movement towards the track travelling trolley, and the dumping angle of the anti-running limiter can be controlled to be 2-4 degrees. The lower part of the anti-running limiter is provided with a portal structure 22 which spans on the track, and two anti-running clamping blocks 21 are respectively arranged in two sides of the portal structure. For easy to assemble, prevent running the fixture block and fix at the two inside walls of portal structure through bolt 23. The upper end of the anti-running limiter is higher than the rail, the upper end of the anti-running limiter is provided with a pin shaft hole 27, a connecting chain pin shaft 41 is arranged in the pin shaft hole 27, and the distance L from the connecting chain pin shaft 41 to the rail surface 32 of the rail is not smaller than 2.5 times of the width W of the anti-running limiter.
The running stop 20 is seated on the rail surface 32 of the rail, with the front end surface 2a of the running stop facing the rail traveling car 10, the front end surface 2a of the running stop being perpendicular to the rail, i.e., perpendicular to the rail surface 32 of the rail. The upper side of the anti-running limiter portal structure is provided with a sliding surface 25, the sliding surface 25 slides on a rail surface 32, and one end of the sliding surface, facing the rail traveling trolley, is provided with a tilting slope angle 26. The angle α of the dump ramp angle 26 is 6 °.
The rear end of the track traveling trolley is provided with a push arm 50 for pushing the anti-running limiter 20 to move, and the push arm 50 is fixed at the rear end of the track traveling trolley through a bolt 54. The push arm 50 is provided with a push plate 51 for pushing the anti-running limiter, the push plate 51 extends out of the rear end of the track traveling trolley for a distance S, and the plate surface of the push plate is parallel to the front end surface 2a of the anti-running limiter, namely, the plate surface of the push plate is also perpendicular to the rail surface 32 of the track. The lower edge 52 of the push plate corresponds to the lower edge 24 of the anti-running limiter, and the upper edge 53 of the push plate is higher than the gravity center G of the anti-running limiter.
The upper end of the anti-running limiter is connected with the track traveling trolley through a connecting chain 40, the connecting chain 40 is a metal chain, and two ends of the connecting chain are respectively provided with a horseshoe ring 42. One section of the connecting chain is hinged with a connecting chain pin shaft 41 at the upper end of the anti-running limiter through a horseshoe ring, and the other section of the connecting chain is hinged with the track traveling trolley through the horseshoe ring.
When the track traveling trolley 10 moves backward (in the direction B in which the traction wire rope 11 is pulled), the push plate 51 can push the running stop 20, and the front end face 2a of the running stop is perpendicular to the track due to the fact that the push plate is higher than the gravity center G of the running stop, and the running stop slides backward on the track 30 in a vertical state under the action of horizontal pushing force.
Once the traction wire rope breaks, as shown in fig. 8, the belt 12 pulls the track traveling trolley 10, and the track traveling trolley pulls the anti-running limiter 20 through the connecting chain 40, because the hinge position of the connecting chain and the anti-running limiter is much higher than the rail surface of the track, and friction exists between the rail surface 32 and the sliding surface 25 of the anti-running limiter, the pulling force F of the connecting chain can generate a moment for enabling the anti-running limiter to topple towards the track traveling trolley, and the anti-running limiter topples. When the connecting chain further pulls the anti-running limiter, the moment generated by the connecting chain can enable the anti-running limiter (comprising the anti-running clamping block 21) to be clamped on the track, and a stopping effect is generated, so that the track traveling trolley is prevented from running in the direction of pulling the belt.
The utility model adopts the metal chain as the connecting chain, the metal chain has good tensile strength, and also has certain buffer function, thus ensuring the working safety.
To ensure that the pulled anti-run stop produces a tipping rotation, the link chain must pull the anti-run stop at a sufficient height. Due to the difference of working conditions, the friction force between the rail surface of the rail and the sliding surface of the anti-running limiter is different, and according to engineering practice, when the distance between the pull point of the connecting chain and the rail surface of the rail is greater than 2.5 times of the width W of the anti-running limiter, the anti-running limiter can reliably generate tilting rotation.
The inclination of the anti-running limiter can be increased by setting the inclined angle 26. The angle of the incline 26 also improves the contact between the sliding surface 25 of the anti-run stop and the rail surface.
The push plate 51 extends out of the rear end of the track traveling trolley by a distance S, so that the distance between the push plate and the anti-running limiter is relatively close (when the connecting chain is straightened), and when the push plate is contacted with the anti-running limiter, the connecting chain cannot excessively droop and is clamped between the push plate and the anti-running limiter, and the normal movement of the anti-running limiter is affected.
