Abstract

The utility model discloses a drawing line stopping switch, which comprises a switch and a drawing line. The switch is provided with a rotating arm, the two ends of the drawing line are provided with a pressure spring component, the core prod of the pressure spring is arranged with scale, one end of the rotating arm is connected with the middle part of the drawing line, and the drawing line is provided with a euphroe. The drawing line can be tighten, when drawing the drawing line, the drawing force can be transmitted to the rotating arm at once with very quick response; besides, when the drawing line at one side of the rotating arm is broken, the pressure spring component on the drawing line at the other side of the rotating arm can automatically draw the rotating arm to rotate, the switch operates and the operator can find at once and replace the drawing line in time, which improves the reliability. The utility model can be used on belt-typed moving tail, plate-typed moving tail, chain-typed moving tail and other continuous moving machines.

Description

The stay cord emergency stop switch
Technical field
The utility model relates to a kind of switching device, relates in particular to a kind of stay cord emergency stop switch.
Background technology
For guaranteeing that ribbon conveyer, apron conveyor, chain-linked conveyer move safely and reliably, be provided with multiple electric protective device, one of them is exactly the stay cord emergency stop switch of arranging along the conveyer total length.
As shown in Figure 1, existing stay cord emergency stop switch comprises several parts such as switch body 1, stay cord 2, support ring 3, and switch body is provided with pivoted arm 7, and the two ends of pivoted arm 7 are respectively equipped with stay cord 2.Pulling stay cord 2, pivoted arm 7 rotates, switch motion, conveyer stops.One group of controllable length of pull switch is about 30-50m.Like this, patrol and examine personnel and all can spur stay cord 2 nearby, conveyer is stopped in any position unusual circumstance along conveyer.
There is following shortcoming at least in above-mentioned prior art; The stay cord 2 of stay cord emergency stop switch relaxes, and can not tighten, in case tighten, switch will move, when pulling stay cord 2, at first will be with stay cord 2 tensions, and switch could move, and reaction speed is slower.Stay cord 2 is generally thinner in addition, is easy to be subjected to the influence of natural environment and corrosion fracture or be subjected to the collision of external force and rupture.After stay cord 2 fracture, the maintenance personal is if in time find, when running into the emergency operating personnel and spurring stay cord 2, conveyer will can not stop, and reliability is not high.
Summary of the invention
The stay cord emergency stop switch that the purpose of this utility model provides and a kind ofly is swift in response, reliability is high.
The purpose of this utility model is achieved through the following technical solutions:
Stay cord emergency stop switch of the present utility model comprises switch body, and described switch body is provided with pivoted arm, also comprises stay cord, and the two ends of described stay cord are respectively equipped with compression spring component, and an end of described pivoted arm is connected with the middle part of stay cord.
Also be provided with euphroe on the described stay cord.
Described compression spring component comprises housing, and the inside of described housing is provided with core bar, is provided with spring between the inwall of housing and the core bar.
Be carved with scale on the described core bar.
The two ends of described stay cord are separately fixed on the fixed mount.
Described stay cord is provided with a plurality of support rings.
Described stay cord is connected by rope clamp with an end of pivoted arm.
The technical scheme that is provided by above-mentioned the utility model as can be seen, stay cord emergency stop switch described in the utility model, owing to comprise switch body and stay cord, switch body is provided with pivoted arm, the two ends of stay cord are respectively equipped with compression spring component, and an end of pivoted arm is connected with the middle part of stay cord.Therefore stay cord can be tightened, and during the pulling stay cord, can immediately pulling force be passed to pivoted arm, is swift in response; In addition, when the stay cord of pivoted arm one side ruptured, the compression spring component on the stay cord of pivoted arm opposite side can spur pivoted arm automatically and rotate, switch motion, and operating personnel can find immediately, in time change stay cord, have improved reliability.Can use on ribbon conveyer, apron conveyor, chain-linked conveyer and other continuous conveyor.
Description of drawings
Fig. 1 is the structural representation of prior art stay cord emergency stop switch;
Fig. 2 is the structural representation of the utility model stay cord emergency stop switch;
Fig. 3 is the structural representation of compression spring component in the utility model.
Embodiment
The preferable embodiment of the utility model stay cord emergency stop switch as shown in Figure 2, comprise switch body 1, described switch body 1 is provided with pivoted arm 7, also comprises stay cord 2, the two ends of described stay cord 2 are respectively equipped with compression spring component 5, and an end of described pivoted arm 7 is connected with the middle part of stay cord 2.Also be provided with euphroe 4 on the described stay cord 2.
The pivoted arm 7 of switch body 1 both direction to the left and right turns an angle.No matter to which direction rotate, switch all can send stop sign.Specifically an end of stay cord 2 can be fixed on the compression spring component 5, the other end is fixed on the euphroe 4, and euphroe 4 is connected with another compression spring component 5 again, forms a string.Two ends with this string unit are connected with two fixed mounts 6 respectively then.Every about 3m, establish a support ring 3 in the middle of the stay cord 2.Tighten stay cord 2 by euphroe 4, connect with stay cord 2 with the pivoted arm 7 of rope clamp 8 then switch body 1.
As shown in Figure 3, described compression spring component 5 comprises housing 9, and the inside of described housing 9 is provided with core bar 10, and described core bar 10 is provided with scale 11, is provided with spring 12 or other elastomeric element between the inwall of housing 9 and the core bar 10.When tightening stay cord 2 by euphroe 4, level of tightness as required, corresponding graduation mark 12 exposes till the housing on the core bar 10.
If the fracture of the stay cord of a certain side, stay cord is stressed with imbalance, and the compression spring component 5 of opposite side rotates Drawing switch pivoted arm 7, sends stop sign.Thereby improved the reliability of stay cord emergency stop switch.In the use, when ambient temperature has bigger variation, should in time adjust euphroe 4, make stay cord 2 keep the tension force that needs.
Can use on ribbon conveyer, apron conveyor, chain-linked conveyer and other continuous conveyor.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
