Abstract
The utility model discloses a speed measurement and strip breakage protection device for an escalator and a moving pavement. The device comprises a retaining plate, a connecting rod, a contact circular ring, a strip breakage detection switch, a speed measurement wheel, a speed detection switch and a counter weight, wherein the speed measurement wheel is matched with a handrail strip; the counter weight is pivotally connected with a torsion arm; the torsion arm is pivotally connected with a pivot shaft of the speed measurement wheel; the contact circular ring is pivotally connected on the retaining plate; the strip breakage detection switch is arranged on the retaining plate; a contact of the strip breakage detection switch is matched with an axial groove of the contact circular ring; and one end of the connecting rod is fixedly or pivotally connected with the pivot shaft of the speed measurement wheel, while the other end is fixedly connected with a shaft on the contact circular ring. The speed measurement wheel is pressed on the handrail strip under the action of the counter weight; the speed detection switch detects the rotation speed of the speed measurement wheel and transmits a signal to a processor; and when the handrail strip is broken, the connecting rod and the contact circular ring are driven to rotate under the action of the counter weight, and a contact switch is pressed down to transmit the signal to a control box. The device has the advantages of triggering the strip breakage detection switch through the rotation of the contact circular ring, along with light structure. The device can be integrated with speed measurement monitoring.
Description
Technical field
The utility model relates to a kind of escalator or pavement.
Background technology
Present prior art, escalator and automatic pedestrian path are in operational process, when following situation occurring: handrail breaks away from Armrest guide rail; The handrail fracture; The handrail elongation reaches certain-length; The velocity contrast of handrail and step reaches permissible value; Velocity contrast between the handrail reaches permissible value.Need to shut down, carry out general complete overhaul.
Summary of the invention
The purpose of this utility model is: the belt break protection device that tests the speed of a kind of escalator and automatic pedestrian path is provided, and it not only can be monitored the handrail rotating speed, but also can protect broken belt.
The utility model is achieved in that the belt break protection device that tests the speed of a kind of escalator and automatic pedestrian path, it is characterized in that: it comprises adapter plate, connecting rod, contact annulus, broken belt detector switch, fifth wheel, switch for over speed detection and weight;
Fifth wheel cooperates with handrail, and weight articulates with turning round arm, and the pivot of turning round arm and fifth wheel articulates;
The contact annulus is articulated on the adapter plate, and the broken belt detector switch is arranged on the adapter plate, the contact head of broken belt detector switch and the groove fit vertically that contacts annulus;
The pivot captive joint of connecting rod one end and fifth wheel or pivot joint, the other end and contact annulus on the axle captive joint.
The belt break protection device that tests the speed of a kind of escalator of the utility model and automatic pedestrian path, owing to adopt such structure, the effect that the deadweight of weight produces is pressed on the handrail fifth wheel.Straight-line motion with handrail rotates.Switch for over speed detection, the rotating speed of detection fifth wheel.Signal is passed to treater, compare with setting speed.Judge that whether speed is unusual, finishes the operation of testing the speed.The characteristics of this speed measuring device are: rely on weight to make fifth wheel compress handrail, simple in structure, stability is better, and failure rate is extremely low.Even the handrail elongation still can guarantee the substantially invariable thrust between fifth wheel and the handrail, thereby guarantee that handrail moves with fifth wheel.
During broken belt, handrail does not support fifth wheel, and the contact head of inductive switch is positioned at the groove of contact annulus.During broken belt, because of losing the bearing force of handrail, because the action of gravity of weight, drivening rod and contact annulus, together around rotation, contact switch is depressed, thereby sends signal to control box.So it, structure is light and handy, triggers the broken belt detector switch by the rotation that contacts annulus.And can combine together with speed measuring and monitoring.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, the belt break protection device that tests the speed of a kind of escalator and automatic pedestrian path comprise adapter plate 1, connecting rod 2, contact annulus 3, broken belt detector switch 4, fifth wheel 5, switch for over speed detection 6 and weight 7;
Contact annulus 3 is articulated on the adapter plate 1, and broken belt detector switch 4 is arranged on the adapter plate 1, the contact head of broken belt detector switch 4 and the groove fit vertically that contacts annulus 3;
The pivot captive joint of connecting rod 2 one ends and fifth wheel 5 or pivot joint, the other end and contact annulus 3 on the axle captive joint.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
