Abstract
The utility model relates to a stall and broken-belt grasping device for a cam belt-pressing type rubber-belt conveyer, which belongs to a broken-belt protecting device for a rubber-belt conveyer. The utility model is provided with a machine frame, the upper end of which is connected with an eccentric wheel, one side of the eccentric wheel is connected with an electromagnet controller, and the lower end of the machine frame is connected with a belt-pressing plate corresponding to the eccentric wheel. The stall and broken-belt grasping device for cam belt-pressing type rubber-belt conveyer is installed on both sides of a rubber belt of the conveyer; when the rubber belt of the conveyer generates a stalling and a belt breaking phenomena, the utility model can be rapidly rotated downwards to be pressed on the rubber belt and extrude the rubber belt of the conveyer so that the rubber belt stops sliding down. The utility model has the advantages of compact structural design, small size, reliable operation, convenient use, easy restoration after working and obvious economical benefit; when used, the utility model can effectively prevent belt breaking accident from being enlarged or materials from being stacked and control the belt breaking accident at the initial stage; a definite distance is arranged between the rubber belt and the belt pressing plate, so the utility model can keep the rubber belt have no abrasion as well as ensure that the utility model doesn't affect the rubber belt grasping effect when working.
Description
Technical field
The utility model relates to a kind of travelling apron belt break protection device, and the stall of particularly a kind of cam press belt type travelling apron, broken belt are arrested device.
Background technology
At present; the travelling apron belt break protection device of present domestic use is mechanical; below the adhesive tape of travelling apron, be connected with eccentric wheel; the adhesive tape operation of oppositely gliding when the adhesive tape broken belt of travelling apron; when the adhesive tape that glides reaches certain speed, drive eccentric running roller and squeeze and capture the adhesive tape of transferring.Shortcoming: 1. drive eccentric wheel by adhesive tape, functional reliability is poor; 2. under transport the belt broken belt and stall inoperative; 3. for last fortune belt, near the top broken belt time, can not arrest the belt of broken belt point top.
Summary of the invention
The purpose of this utility model is a kind of functional reliability height will be provided, can arrest device to transporting the stall of cam press belt type travelling apron, the broken belt that belt broken belt and stall works simultaneously down.
The purpose of this utility model is achieved in that this arrests device one frame is arranged, and is connected with eccentric wheel in the upper end of frame, is connected with electromagnet controller in an eccentric side, is connected with the pressure zone plate in the lower end and the cooresponding position of eccentric wheel of frame.
Eccentric wheel is one 1/4 circular eccentric wheel, is connected with torque spring in eccentric wheel S. A. position, has one concavo-convex on eccentric sidewall.
Beneficial effect: owing to adopt such scheme, this arrests the both sides that device is installed in travelling apron, when the adhesive tape stall that conveyer takes place, during broken belt, the stall that is detected, the action of break signal control electromagnet controller, extract out in electromagnet armature concavo-convex from the eccentric wheel sidewall, eccentric wheel is under the effect of torque spring, be rotated down rapidly and be pressed on the adhesive tape, the distance between eccentric wheel and the pressing plate has been dwindled in the continuous displacement of adhesive tape, the adhesive tape of extruding conveyer, adhesive tape is stopped gliding, the functional reliability height, can arrest the broken belt and the stall of transporting belt down simultaneously, reach the purpose of this utility model.Advantage: this apparatus structure is compact to design, volume is little, reliable operation, easy to use, and recover easily the action back; In use can effectively prevent the expansion or the solid accumulation of broken belt accident, the broken belt accident is controlled at the starting stage, reduce the broken belt settlement of accident time, remarkable in economical benefits has popularizing application prospect preferably; Between adhesive tape and pressure zone plate, maintain certain distance each other, can keep not grinding adhesive tape, do not influence in the time of guaranteeing mechanism action again and arrest effect tape.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
Embodiment 1: this arrests device a frame 4 above travelling apron, be connected with eccentric wheel 1 in the upper end of frame 4, is connected with electromagnet controller 3 in a side of eccentric wheel 1, is connected with pressure zone plate 5 in the lower end and the eccentric wheel 1 cooresponding position of frame 4.Eccentric wheel 1 is positioned at the top of adhesive tape 6, is connected with carrying roller 8 below adhesive tape 6.Eccentric wheel 1 is one 1/4 circular eccentric wheel, is connected with torque spring 7 in eccentric wheel S. A. position, has one concavo-convex on the sidewall of eccentric wheel 1.
Principle of work: 1. pressure zone cam arcwall face (one side that contacts with adhesive tape) is processed with decorative pattern, but actv. increases the friction force between pressure zone cam arcwall face and adhesive tape, and it is sliding that actv. prevents adhesive tape to amplify.
2. pinch roller is designed to 1/4 cam, when travelling apron generation stall, broken belt backward, and the magnet control mechanism action, the pressure zone cam is transferred under the effect of torque spring and deadweight and is squeezed band, adhesive tape 6 continues to glide, and continues to drive the cam arcwall face, and pressure zone is pressed tighter and tighter.
3. the installation of pressure zone plate 5 is a little less than belt roller 8, and adhesive tape 6 grinds in mechanism in the time of can preventing normal operation.
Claims (2)
1, a kind of cam press belt type travelling apron stall, broken belt are arrested device, it is characterized in that: this arrests device a frame, upper end in frame is connected with eccentric wheel, is connected with electromagnet controller in an eccentric side, is connected with the pressure zone plate in the lower end and the cooresponding position of eccentric wheel of frame.
2, cam press belt type travelling apron according to claim 1 stall, broken belt are arrested device, it is characterized in that: eccentric wheel is one 1/4 circular eccentric wheel, is connected with torque spring in eccentric wheel S. A. position, has one concavo-convex on eccentric sidewall.
