Detailed description of the invention
below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be those skilled in the art will recognize that thus make more explicit defining to protection scope of the present invention.
shown in composition graphs 1, the present invention is a kind of overload protection device for chain delivery machanism 1, and this chain delivery machanism 1 is used in cleaning machine, and load-transfer device 11 used is guipure.Direction shown in the arrow of Fig. 1 middle and upper part is the transmission direction of load-transfer device 11, and direction shown in the arrow at right part second sprocket wheel 21 place is the rotation direction of the second sprocket wheel 21.Multiple first sprocket wheels 12 that described chain delivery machanism is comprised load-transfer device 11, is connected by described load-transfer device 11, load-transfer device 11 is driven by least one drive sprocket, and drive sprocket is by the motor-driven rotation of chain delivery machanism.When load-transfer device 11 is because of reason overloads such as jams; load-transfer device 11 is owing to being subject to resistance or friction force and being tending towards running slowly; but because chain delivery machanism is still in running state; drive sprocket still orders about load-transfer device 11 with normal speed drive and runs; this is tending towards increasing with regard to making the tension force of load-transfer device 11; if shut down by chain delivery machanism not timely, then the tension force of load-transfer device 11 increases further until load-transfer device 11 is pulled bad even breaks.
shown in composition graphs 1 to Fig. 3, described overload protection device 2 comprises frame, the second sprocket wheel 21 rotated is driven by motor, there is the detection zone 22 of pilled-in selvedge and slack list, be arranged at the detection wheel 20 in frame actively, be fixedly installed on the first sensor 28 in frame, described detection zone 22 drives running by the second sprocket wheel 21 and the pilled-in selvedge of detection zone 22 and the second sprocket wheel 21 have a contact point A, one of them described first sprocket wheel 12 to be connected with the second sprocket wheel 21 by detection zone 22 and this first sprocket wheel 12 has a contact point B with the pilled-in selvedge of detection zone 22, described detection wheel 20 rollably contacts with the pilled-in selvedge of detection zone 22 and has a contact point C mutually, when described load-transfer device 11 normal operation, as shown in phantom in Figure 1, contact point A, B, C forms a triangle, when by jam, tension force increases described load-transfer device 11, as shown in solid lines in fig. 1, contact point C is close to the line of contact point A, B, and described first sensor 28 detects that detecting wheel 20 moves, and described conveying mechanism is shut down.Described detection wheel 20 is positioned at the outside of detection zone 22, described second link is positioned at the below detecting wheel 20, described induction wheel 27 is positioned at the below detecting wheel 20, swing component 23 is arranged in frame rotationally by a rotating shaft 24, and rotating shaft 24 has certain distance apart from the first end of swing component 23 and the second end.
this overload protection device also comprises the attaching parts 26 that a swing component 23, be arranged at rotationally in described frame has relative first end and the second end; described swing component 23 has relative first end and the second end; described detection wheel 20 is arranged on the first end of swing component 23 rotationally, and the second end of described swing component 23 is connected in frame actively by a return unit.The first end of described attaching parts 26 is connected to frame rotationally; second end of described attaching parts 26 is provided with an induction wheel 27 rotationally; described induction wheel 27 rollably contacts all the time mutually with the second end of swing component 23; when by jam, tension force increases described load-transfer device 11; described induction wheel 27 moves to the induction region place of first sensor 28, and described conveying mechanism is shut down.
what described frame was also fixed is provided with one second sensor 29; when the tension force of described load-transfer device 11 is too small; the line of contact point C contact point A, B further away from each other, described induction wheel 27 moves to the induction region place of the second sensor 29, and described conveying mechanism is shut down.When chain delivery machanism normally runs, induction wheel 27 is just to a zero position, and first sensor 28 and the second sensor 29 lay respectively at the both sides of zero position.The maximum tension that first sensor 28 should can bear according to load-transfer device 11 apart from the distance of zero position and setting, with ensure when first sensor 28 by detect induction wheel 27 sense detection wheel 20 move right time, the tension force still unlikely fracture in tolerance range of load-transfer device 11.The minimum tension that second sensor 29 can should drive transported material to run according to load-transfer device 11 apart from the distance of zero position and setting, detect before wheel 20 is moved to the left to ensure can sense at the second sensor 29, load-transfer device 11 can both have enough tension force to transport transported material.When load-transfer device 11 tension force increases; detecting wheel 20 drives the second end of swing arm to swing left; induction wheel 27 is moved to the left thereupon; when entering into the monitored area of first sensor 28 to induction wheel 27; first sensor 28 detects signal, and then sends signal by control conveying mechanism shutdown such as controllers.
described first return unit is spring, specific in the present embodiment for extension spring 25.Extension spring 25 1 aspect resets to make detection take turns 20, the sensitivity of adjustable detection on the other hand.
described detection zone 22 is chain, and described detection wheel 20 is sprocket wheel, and described detection wheel 20 is meshed with the pilled-in selvedge of detection zone 22.
when the load-transfer device 11 jammed moment of chain delivery machanism, drive sprocket due to load-transfer device 11 is still driven by the motor of conveying mechanism and carries out high-speed operation, the instantaneous tension force of load-transfer device 11 is then made to increase, first sprocket wheel 12 of load-transfer device 11 slows down or stall, and the second sprocket wheel 21 still drives normal operation by the motor of overload protection device, then making the tension force of detection zone 22 pilled-in selvedge constantly increase makes the pilled-in selvedge of detection zone 22 constantly tighten, i.e. contact point A, distance between C and contact point C, distance sum between B constantly reduces, and then promotion detection wheel 20 moves, when first sensor 28 to sense by detecting induction wheel 27 and whether arriving its monitored area detect wheel 20 mobile time, send control signal, and then control chain delivery machanism shutdown, the tension force of real time on-line monitoring load-transfer device 11, tension force continues to increase because of reasons such as jams to avoid load-transfer device 11, prevent load-transfer device 11 from being pulled bad or breaking.
above-described embodiment for technical conceive of the present invention and feature are described, is only a kind of preferred embodiment, its object is to person skilled in the art and can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.The equivalent transformation that all Spirit Essences according to the present invention are done or modification, all should be encompassed within protection scope of the present invention.
