Abstract
The utility model discloses an emergency pullswitch of a spring type belt channel. The emergency pullswitch comprises a piston sleeve, wherein a base connected with a belt rail frame is arranged on the outer wall of the piston sleeve, a front retaining cap of which the middle is provided with through holes is installed at the front end of the piston sleeve, and a rear retaining cap is installed at the rear end of the piston sleeve; the piston sleeve is further internally provided with a spring, the front end of the spring is fixedly installed at the rear end of the front retaining cap, and the rear end of the spring is connected with a piston; a piston rod is fixedly installed on the front end face of the piston, and passes through the interior of the spring and the through holes, and a traction ring is arranged at the front end of the piston rod. The emergency pullswitch further comprises a steel wire rope which passes through the whole belt channel along the belt channel and also passes through the traction ring; an armature induction proximity switch is installed in the rear retaining cap, and the front end of a contact of the armature induction proximity switch penetrates into the piston sleeve and is close to the piston. When a belt needs to stop suddenly, a belt conveyor can be instantaneously controlled to stop, so that the damage to the belt conveyer and the belt is alleviated to the maximum extent and the field safety factor is improved.
Description
technical field
The utility model relates to the emergent pullswitch in a kind of belt road.
background technology
Guarantee personal safety, protect belt to avoid damaging and guarantee belt feeder safe operation, generally in the transportation of mine adopt emergent pullswitch as the emergency stop switch of belt feeder.
Existing emergent pullswitch operated by rotary motion is in down-hole and near belt feeder electric-control system, because distance between operator and switch is uncertain, while being in an emergency, can not guarantee that the very first time stops belt feeder operation, be easy to cause the damage of belt feeder and belt, but also have many potential safety hazards.
In view of above situation, in order to ensure belt feeder safe operation, make belt road emergency switch really reach object safely and efficiently, research and develop and a kind ofly can be applicable to various environment, the emergent pullswitch in spring loaded belt road that particularly subsurface environment is used is industry technical matters urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is, by a kind of spring loaded belt road pullswitch of meeting an urgent need is provided, can in mine, handle any position to emergency switch, needs the anxious stopping time of belt can control belt feeder moment and shuts down.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The spring loaded belt road pullswitch of meeting an urgent need, is characterized in that: it comprises piston bush, is provided with the base for being connected with belt rail bracket on the outer wall of described piston bush, and the front end of piston bush is provided with middle part with the front cap of through hole, and rear end is provided with backstop cap; In described piston bush, be also provided with spring, the front end of spring is fixedly mounted on the rear end of front cap, and rear end is connected with piston; On the front end face of described piston, be installed with piston rod, described piston rod passes from spring inner and described through hole, and front end is provided with eye hitch; Also comprise the steel rope that runs through whole belt road along belt road trend, eye hitch described in described steel wire penetrating; In described backstop cap, armature inductive proximity switch is installed, the contact front end of described armature inductive proximity switch is deep in piston bush and is mutually close with described piston.
Good effect of the present utility model is: need the anxious stopping time of belt, no matter in any position, belt road, as long as touching steel rope promotes piston backward, armature inductive proximity switch contact is contacted with piston, armature inductive proximity switch exports control signal, with belt feeder electric-control system interlocking, control belt feeder and stop.At utmost alleviate the damage of belt feeder and belt, improved site safety coefficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
the specific embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
As Fig. 1, the utility model comprises piston bush 2, is provided with the base 8 for being connected with belt rail bracket on the outer wall of described piston bush 2, and the front end of piston bush 2 is provided with middle part with the front cap 3 of through hole 5, and the rear end of piston bush 2 is provided with backstop cap 1.In described piston bush 2, be also provided with spring 7, the front end of stating spring 7 is fixedly mounted on the rear end of front cap 3, and the rear end of spring 7 is connected with piston 9.
On the front end face of described piston 9, be installed with piston rod 6.Described piston rod 6 passes from the described through hole 5 of spring 7 inside and front cap 3, and front end is provided with eye hitch 4.
The utility model also comprises the steel rope that runs through whole belt road along belt road trend, and eye hitch 4 and two ends are separately fixed on the support on the sidewall in belt road described in described steel wire penetrating.
In described backstop cap 1, armature inductive proximity switch 10 is installed, the contact front end of described armature inductive proximity switch 10 is deep in piston bush 2 and is mutually close with described piston 9.The wire of armature inductive proximity switch 10 is for being connected with belt feeder electric-control system.
Under normal condition, at the contact of the tractive lower armature inductive proximity switch 10 of steel rope, do not contact with piston 9.Need the anxious stopping time of belt, no matter in any position, belt road, as long as touching steel rope promotes piston 9 backward, described contact is contacted with piston 9, armature inductive proximity switch 10 exports control signal, with belt feeder electric-control system interlocking, controls belt feeder and stops.Must can release after manual reset.
100 meters of belt road length need to install a switch of the present utility model with interior just can realize safety guard-safeguard, and 100 meters above can install two or change high elastic force spring.
