Abstract
The utility model discloses a roadway caving transfer chute which comprises a chute body. The bottoms of the two ends of the chute body are connected with a pair of long supporting legs and a pair of short supporting legs respectively in a hinged mode, the supporting legs are used for adjusting the height of the two ends of the chute body, a telescopic connecting rod is hinged to one of the long supporting legs, the end portion of the telescopic connecting rod is connected with the lower portion of the chute body to prevent the chute body from swinging left and right, and the two sides of the upper portion of the chute body are connected with a steel chain to prevent the chute body from toppling. The roadway caving transfer chute is simple in structure, convenient to adjust, strong in on-site applicability and good in safety, can effectively improve roadway caving efficiency, and guarantees a safe, continuous and efficient roadway caving process.
Description
Technical field
The utility model relates in Roadway Sub-Level Caving reprints the transfer chute in drag conveyor by the roadway roof coal of emitting.
Background technology
In Roadway Sub-Level Caving process, in view of tunnel coal discharge outlet and drag conveyor have certain space distance, need to adopt transfer chute connect tunnel coal discharge outlet and drag conveyor, thereby the top coal that tunnel coal discharge outlet is emitted is reprinted on drag conveyor.Existing common transfer chute exists efficiency low, and the deficiencies such as poor stability, need further improvement.
Utility model content
The purpose of this utility model is to provide a kind of transfer chute being applicable in Roadway Sub-Level Caving process.
The technical solution that the utility model adopts is:
Roadway Sub-Level Caving transfer chute, comprise chute body, bottom, the two ends hinged a pair of long support leg of difference and a pair of short supporting leg at chute body, a hinged extensible link on a wherein long support leg of a pair of long support leg, the end of extensible link is connected with the bottom of chute body, and the both sides, top of chute body are connected with a steel chain respectively.
Preferably, in the end of extensible link and two steel chains, be provided with hook, in bottom and the both sides, top of chute body, be provided with and link up with the nose-ring matching.
Preferably, described extensible link comprises first connecting rod and second connecting rod, one end coupling hook of first connecting rod, the other end of first connecting rod is provided with screw thread, one end of second connecting rod and long support leg are hinged, the other end of second connecting rod connects a sleeve pipe, in sleeve pipe inner side, is provided with thread groove, and first connecting rod is established threaded end and is screwed in sleeve pipe.
Preferably, the cross section of described chute body is semicircle.
Useful technique effect of the present utility model is:
This utility structure is simple, easy to adjust, and on-the-spot applicability is strong, and safety is good, can effectively improve Roadway Sub-Level Caving work efficiency, ensures the safe, continuous, efficient of tunnel drawing coal technology process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view.
In figure: 1-chute body, 2-long support leg, the short supporting leg of 3-, 4-drag conveyor, 5-extensible link, 501-first connecting rod, 502-second connecting rod, 503-screw thread, 504-sleeve pipe, 6-hook, 7-nose-ring, 8-steel chain.
The specific embodiment
By reference to the accompanying drawings, Roadway Sub-Level Caving transfer chute, comprises chute body 1, and the length of chute body 1 can be set according to on-site actual situations, and the cross section of chute body 1 is semicircle.At the hinged a pair of long support leg 2 of the bottom, two ends of chute body 1 difference and a pair of short supporting leg 3, for regulating the height at chute body 1 two ends.The length of short supporting leg should be greater than the height of 1.5 times of drag conveyors 4, and the length of long support leg should be greater than the length of 2 times of short supporting legs 3.In the wherein hinged extensible link 5 of long support midleg of a pair of long support leg, the end of extensible link 5 is connected with the bottom of chute body 1, prevents that chute body 1 from vacillating now to the left, now to the right.Extensible link 5 comprises first connecting rod 501 and second connecting rod 502, and one end of first connecting rod 501 is provided with screw thread 503, and the other end coupling hook 6 of first connecting rod 501, at the welding of the bottom of chute body 1 and hook 6 nose-rings that match 7.One end of second connecting rod 502 and long support leg are hinged, and the other end of second connecting rod 502 connects a sleeve pipe 504, in sleeve pipe 504 inner sides, are provided with thread groove.First connecting rod 501 is established threaded end and is screwed in sleeve pipe 504.The degree of depth that is screwed into sleeve pipe 504 by first connecting rod 501 realizes the flexible of extensible link.The both sides, top of chute body 1 are connected with a steel chain 8 respectively.The top of steel chain 8 is fixedly connected with top board girder steel, and the bottom of steel chain 8 is provided with hook 6, at two symmetrical nose-rings 7 of the both sides, top of chute body 1 welding.Steel chain 8 plays the effect that prevents that chute body 1 from skewing.
The relevant technologies content of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
It should be noted that, under the instruction of this manual, any equivalents that those skilled in the art have done, or obvious variant, all should be within protection domain of the present utility model.
