Description
Technical field
The utility model relates to the technical field of switching device, especially a kind of bidirectional pull switch device.
Background technology
Pull switch is the indispensable fender guard of belt conveyer, when needing for belt conveyer generation emergency episode or maintenance to shut down, can pull steel rope, make conveyer emergency engine kill.
But existing most of pull switch still comes with some shortcomings part in mechanism design, most pull switch to need in specific position just stretchy steel rope, largely reducing the scope that it uses.Meanwhile, when using hand reset, when maintainer does not withdraw or remains under other abnormal condition, conveyer will exist by the hidden danger of error starting, and the safety of maintainer can not get good guarantee.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provides a kind of manipulation convenient, safe and reliable bidirectional pull switch device.
The utility model solves the technical scheme that its technical matters adopts: a kind of bidirectional pull switch device, there is circular shell, described circular shell rear surface is provided with reaction plate with one heart, front surface eccentric setting has rotating disc, described rotating disc is hinged with rocking arm, the two ends of described rocking arm are hinged with draw ring one and draw ring two respectively, described draw ring one and draw ring two are in 360 degree of distributions, draw ring one is connected by stay cord transition with the draw ring two of adjacent switch device, and the draw ring one of the adjacent switching device of draw ring two is connected by stay cord transition; Rotating disc is also hinged with the operating handle started or stoped for controlling rocking arm.
Further specifically, the side of described circular shell is provided with outlet device.
Further specifically, the bottom of described circular shell is provided with the fixed pedestal pin of two mirror image distributions.
Further specifically, described circular shell front surface is also provided with the limiting stopper for limiting rocking arm primary position, the initial position of rocking arm is that draw ring one is positioned at directly over draw ring two.
The beneficial effects of the utility model are: bidirectional pull switch device of the present utility model has the following advantages:
(1) this switch can pull steel rope along optional position, and then makes conveyer at any time can carry out emergency engine kill, ensure that urgent danger prevention or the orderly closedown maintenance of conveyer;
(2), when using hand reset, when maintainer does not withdraw or remains under other abnormal condition, only need the position locking the switch in shutdown, just do not worry that conveyer is by error starting, ensured the personal safety of maintainer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, circular shell, 2, reaction plate, 3, rotating disc, 4, rocking arm, 5, draw ring one, 6, draw ring two, 7, operating handle, 8, outlet device, 9, fixed pedestal pin, 10, limiting stopper.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of bidirectional pull switch device, there is circular shell 1, described circular shell 1 rear surface is provided with reaction plate 2 with one heart, front surface eccentric setting has rotating disc 3, described rotating disc 3 is hinged with Rocker arm 4, the two ends of described Rocker arm 4 are hinged with draw ring 1 and draw ring 26 respectively, described draw ring 1 and draw ring 26 are in 360 degree of distributions, draw ring 1 is connected by stay cord transition with the draw ring 26 of adjacent switch device, and draw ring 26 is connected by stay cord transition with the draw ring 1 of adjacent switch device; Rotating disc 3 is also hinged with the operating handle 7 started or stoped for controlling Rocker arm 4.
Wherein, the side of described circular shell 1 is provided with outlet device 8.The bottom of described circular shell 1 is provided with the fixed pedestal pin 9 of two mirror image distributions.Described circular shell 1 front surface is also provided with the limiting stopper 10 for limiting Rocker arm 4 primary position, the initial position of Rocker arm 4 is that draw ring 1 is positioned at directly over draw ring 26.
This bidirectional pull switch device can be widely used in the various load transfer devices specializing in Bulk material in the fields such as metallurgy, coal, cement, mining, electric power, chemical industry.As conventional band conveyor, reciprocating conveyor, group limit formula feed conveyer, bucket carrier, packaging production line, hoisting crane, excavating machine, steamer loading and unloading system, horizontal-feeding and etc.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
