Abstract
The utility model discloses a reinforced concrete sleeper easy to dismount and mount for mines. The reinforced concrete sleeper easy to dismount and mount for the mines comprises a sleeper body and an elastic bar clamping board fixed to the upper surface of the sleeper body. An elastic bar clamping groove is formed in the elastic bar clamping board, and an elastic bar used for fixing a steel rail is connected to the interior of the elastic bar clamping groove in a clamping mode. The sleeper body comprises a concrete sleeper body and a reinforcing rib frame arranged in the concrete sleeper body. Due to the fact that the elastic bar clamping board is arranged on the sleeper, the steel rail can be fixed and dismounted conveniently by mounting and dismounting the elastic bar, and the sleeper is easy to mount and dismount, high in recovery rate and capable of being used repeatedly. Meanwhile, reinforcing ribs are arranged in concrete, so that the strength of the sleeper is enhanced, and the stability of the sleeper is enhanced.
Description
Technical field
The utility model relates to a kind of mine steel bar concrete sleeper easy to assemble.
Background technology
As everyone knows, existing mine using railroad tie generally comprises concrete sleeper body and is arranged on the fixing hole of the rail on concrete sleeper body, in use by rail by fixing hole be bolted on concrete sleeper body.Such concrete sleeper dismounting is more complicated, and being not suitable for mine using railroad tie needs the often demand of dismounting, and concrete sleeper body intensity is lower simultaneously, can not adapt to the demand of modern mineral exploration and exploitation.It is a kind of easy to assemble that prior art is badly in need of, the large and constitutionally stable mine using railroad tie of intensity.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of easy to assemble, the large and constitutionally stable mine using railroad tie of intensity.
For achieving the above object, the technical solution of the utility model has been to provide a kind of mine steel bar concrete sleeper easy to assemble, described mine steel bar concrete sleeper easy to assemble comprises sleeper body and is fixed on the spring clamp of sleeper body upper surface, described spring clamp is provided with spring draw-in groove, is connected with for the fixing spring of rail in described spring draw-in groove; Described sleeper body comprises concrete sleeper body and is arranged on the intrinsic steel bar framework of concrete sleeper.By spring clamp is set on sleeper, can be easily by installation and removal spring, realize the fixing and dismounting of rail, like this since sleeper described in the utility model easily press readily removablely, the rate of recovery is high, repeatedly Reusability; The intensity that reinforcing bar can strengthen sleeper is set in concrete, its stability is strengthened simultaneously.
As preferably, described sleeper body is the higher concave character type sleeper in lower two ends, middle part, and described spring clamp is arranged on the upper surface of both sides, sleeper body middle part projection, and described spring clamp is fixedly connected with sleeper body by steel part.Concave character type sleeper is from heavy and light, and force structure is reasonable, and moulding is easy, when mine car travels, can avoid the connection chain sleeper of breaking while jolting.Mining narrow gauge light rail load is light in addition, does not generally establish rail support groove.
As preferably, in described sleeper body, be provided with transverse reinforcement, described transverse reinforcement comprises the fine steel rib that is arranged on sleeper body top and the bar reinforcement that is arranged on sleeper body bottom, between described fine steel rib and bar reinforcement, by connecting reinforcement, is welded to connect.Such design makes sleeper strength larger, and sleeper body bottom and top thickness are distinguished design and made to make the best use of everything.
Advantage of the present utility model and beneficial effect are: by spring clamp is set on sleeper, can by installation and removal spring, realize easily the fixing and dismounting of rail, like this, sleeper described in the utility model is easily by readily removable, the rate of recovery is high, repeatedly Reusability; The intensity that reinforcing bar can strengthen sleeper is set in concrete, its stability is strengthened simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A place structure enlarged diagram in Fig. 1.
In figure: 1, sleeper body; 2, spring clamp; 3, spring draw-in groove; 4, rail; 5, spring; 6, steel bar framework; 7, steel part; 8, fine steel rib; 9, bar reinforcement; 10, connecting reinforcement.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of mine steel bar concrete sleeper easy to assemble, described mine steel bar concrete sleeper easy to assemble comprises sleeper body 1 and is fixed on the spring clamp 2 of sleeper body 1 upper surface, described spring clamp 2 is provided with spring draw-in groove 3, is connected with for the fixing spring 5 of rail 4 in described spring draw-in groove 3; Described sleeper body 1 comprises concrete sleeper body and is arranged on the intrinsic steel bar framework 6 of concrete sleeper.
Described sleeper body 1 is the higher concave character type sleeper in lower two ends, middle part, and described spring clamp 2 is arranged on the upper surface of sleeper body 1 both sides, middle part projection, and described spring clamp 2 is fixedly connected with sleeper body 1 by steel part 7.
In described sleeper body 1, be provided with transverse reinforcement, described transverse reinforcement comprises the fine steel rib 8 that is arranged on sleeper body 1 top and the bar reinforcement 9 that is arranged on sleeper body 1 bottom, between described fine steel rib 8 and bar reinforcement 9, by connecting reinforcement 10, is welded to connect.
During use, as long as each sleeper body 1 is laid, after allowing, rail 4 is placed on predetermined spring clamp 2, by spring 5, rail 4 can be used, remove also very simple.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
