Abstract
The utility model discloses a mine track limiting device, relates to the field of equipment for coal mines, and provides the mine track limiting device capable of preventing changing of track spacing. The mine track limiting device comprises a connecting shaft and two limiting blocks. The limiting blocks are provided with track grooves with the shapes corresponding to the shapes of the lower portions of tracks. The connecting shaft comprises a middle segment and thread segments located at the two sides of the middle segment, wherein the thread segments are provided with nuts. The two limiting blocks are arranged on the two thread segments in a sleeved mode and are fixed through the nuts, and the distance between the two limiting blocks is the track spacing. The mine track limiting device can be arranged in a special area of transport to limit and fix the transport tracks to prevent the situation of the excessively wide transport track spacing or excessively wide gaps between tracks when heavy equipment passes through or roadways deform, so that it is guaranteed that the transport equipment cannot be derailed, and the transport equipment can transport materials safely, quickly and efficiently.
Description
Technical field
The utility model relates to colliery apparatus field, relates in particular to a kind of mining rail stopping means.
Background technology
At present, along with colliery is to mechanization, large scale development, comprehensive mechanization mining machinery is used widely in coal mining enterprise.Heavy, superduty digging electromechanical equipment is frequent at colliery underground transportation, the transportation of digging electromechanical equipment is more and more higher to mine conveying track quality requirement, to sleeper, track space, between rail, gap requires also more and more stricter, otherwise in the time of transportation jumbo, because being subject to mine pressure, tunnel affects after distortion, easily cause track space, between rail, gap is super wide, particularly turn round in tunnel, climb and fall, the special location such as parking lot, digging electromechanical equipment by time easily slide down, sport car, process extremely difficult, often there is the Electromechanical Transportation security incident of casualties, potential safety hazard is large.
Utility model content
The technical problems to be solved in the utility model is: a kind of mining rail stopping means that can prevent that track space from changing is provided.
For the technical scheme that addresses the above problem employing is: mining rail stopping means comprises connecting axle and two limited blocks; On limited block, be provided with the rail groove corresponding with track lower shape with shape; Connecting axle comprises interlude and is positioned at the thread segment on interlude both sides, is provided with nut on thread segment; Two limited blocks are set with on two thread segments and fix by nut, and the distance between two limited blocks is track space.
Further: on thread segment, be provided with two nuts, limited block is fixed between two nuts.
Further: on thread segment, be provided with a nut, limited block is fixed between nut and interlude.
The beneficial effects of the utility model are: two tracks are penetrated respectively to two rail grooves, and because limited block spacing position is connected axis limit, track space is also defined.This mining rail stopping means is installed in special location in transportation, the fixing conveying track of restriction, can prevent jumbo by or roadway deformation situation under between conveying track spacing, rail gap super wide, guarantee that haulage device does not slide down, make haulage device efficient transportation material safely and fast.
Accompanying drawing explanation:
Fig. 1 is that a kind of embodiment of mining rail stopping means uses state diagram;
Fig. 2 is that the another kind of embodiment of mining rail stopping means uses state diagram;
In figure, be labeled as: thread segment 1, limited block 2, track 3, rail groove 4, nut 5, interlude 6, connecting axle 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Mining rail stopping means comprises connecting axle 7 and two limited blocks 2; On limited block 2, be provided with the rail groove 4 corresponding with track 3 lower shapes with shape; Connecting axle 7 comprises interlude 6 and is positioned at the thread segment 1 on interlude 6 both sides, is provided with nut 5 on thread segment 1; Two limited blocks 2 are set with on two thread segments 1 and by nut 5 to be fixed, and the distance between two limited blocks 2 is track space.
When use, the wavesons such as the gangue of cleaning under mining rail 3, assemble rear cover by mining rail stopping means and install on track 3 (being that track 3 inserts rail groove 4) and be put into track 3 belows.When the assembling of mining rail stopping means, should guarantee that two distances between limited block 2 are identical with two orbit theory distances.
The mode of nut 5 fixing limited blocks 2 can be as shown in Figure 1, is provided with two nuts 5 on thread segment 1, and limited block 2 is fixed between two nuts 5.Also on thread segment 1, be provided with a nut 5 as shown in Figure 2, limited block 2 is fixed between nut 5 and interlude 6.
In order to improve the fastening effect of nut 5, can take to arrange the conventional locking measures such as spring washer.
