Abstract
The utility model discloses an automatic alarm protection device for tension interference of a belt, which can provide reliable protection when the belt tension is over large. The automatic alarm protection device comprises a belt conveyer, wherein a belt conveyer fixing frame, a belt conveyer tension drum and a belt conveyer comprehensive protector are designed on the belt conveyer; a hydraulic jack is designed between the belt conveyer fixing frame and the belt conveyer tension drum; the two ends of the hydraulic jack are connected with a connecting device respectively; one end of the hydraulic jack is connected with the belt conveyer tension drum through a belt tension rope, and the other end of the hydraulic jack is connected with the belt conveyer fixing frame through a wire rope; the hydraulic jack is fixedly connected with a pressure gauge with electric contact; and the pressure gauge with electric contact is connected with a belt conveyer comprehensive protection switch through a pressure load line.
Description
Technical field
The utility model relates to a kind of interference fender guard, relates in particular to a kind of belt tension tension interference automatic alarm protecting.
Background technology
The integrated protection of present each colliery general-duty belt transportation system; Generally be provided with following protection: coal piling, smog, overtemperature watering, sideslip, speed, tear band, along the line anxious protection such as stop; In the production application process, can't change and realize protection, can not satisfy on-the-spot demand fully the tension of belt.When the belt transportation distance is grown or other unforeseen circumstancess occurred; Because excessive the causing of belt tension drawn bad belt head fixed border frame; Draw the race belt machine end, change the angle of belt tension car, cause belt to tear band, winding; Even break serious accident such as belt, the personal safety that influence is produced even jeopardized the field operation personnel.
Summary of the invention
The purpose of the utility model provides and a kind ofly when the belt tension is excessive, reliable protection can be provided, and guarantees the belt tension tension interference automatic alarm protecting of belt normal operation.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of belt tension tension interference automatic alarm protecting; Comprise belt feeder; Be designed with belt feeder fixed mount, belt feeder tensioner cylinder and integrated belt machine protection machine on the belt feeder, it is characterized in that: be designed with hydraulic jack between described belt feeder fixed mount and the belt feeder tensioner cylinder, the two ends of hydraulic jack are connected with connecting device respectively; Hydraulic jack one end is connected with belt feeder tensioner cylinder through the belt tension rope; The other end of hydraulic jack is connected with the belt feeder fixed mount through steel rope, is fixedly connected with electro connecting pressure gauge on the hydraulic jack, and electro connecting pressure gauge is connected with the integrated belt machine protection switch through the pressure load line.
The utility model has the advantages of and be: because the utility model utilizes jack and electro connecting pressure gauge; So can the belt tension be changed into electric signal; Electric signal is transferred to the integrated belt machine protection switch; Send alerting signal, break off the belt feeder power supply simultaneously, reach the protection belt purpose of normal operation under any circumstance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the another kind of structural representation of the utility model;
Fig. 3 is the electrical schematic diagram of the utility model;
Fig. 4 is the structural representation of integrated belt machine protection switch.
In the accompanying drawing: 1, belt feeder tensioner cylinder; 2, connecting device; 3, electro connecting pressure gauge; 4, integrated belt machine protection switch; 5, belt feeder fixed mount; 6, steel rope; 7, hydraulic jack; 8, belt tension rope.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
The utility model is like Fig. 1,2,3, shown in 4; A kind of belt tension tension interference automatic alarm protecting; Comprise belt feeder; Be designed with belt feeder fixed mount 5, belt feeder tensioner cylinder 1 and integrated belt machine protection machine 4 on the belt feeder, it is characterized in that: be designed with hydraulic jack 7 between described belt feeder fixed mount 5 and the belt feeder tensioner cylinder 1, the two ends of hydraulic jack 7 are connected with connecting device 2 respectively; Hydraulic jack 7 one ends are connected with belt feeder tensioner cylinder 1 through belt tension rope 8; The other end of hydraulic jack 7 is connected with belt feeder fixed mount 5 through steel rope 6, is fixedly connected with electro connecting pressure gauge 3 on the hydraulic jack 7, and electro connecting pressure gauge 3 is connected with integrated belt machine protection switch 4 through the pressure load line.In the present embodiment, connecting device 2 is for connecting pulley.
Use the utility model; The jack that will have electro connecting pressure gauge is fixed between belt feeder fixed mount and the belt feeder tensioner cylinder; The piston rod of jack is connected with the belt tension rope through connecting device; When tension changed, piston rod was flexible along with tension changes, and tension is changed into pressure; Pressure signal after the change is sent on the electro connecting pressure gauge, makes it to become electric signal; When pressure changed the setting value that surpasses electro connecting pressure gauge, the electric contact corresponding actions was transferred to belt integrated protection main frame with electric signal, sends alerting signal, breaks off the belt feeder power supply simultaneously, reaches the purpose of protection.
Use the utility model, the one, for long when the belt transportation distance or when other unforeseen circumstancess occurring, owing to excessive the causing of belt tension drawn bad belt head fixed border frame; Draw the race belt machine end, change the angle of belt tension car, cause belt to tear band, winding; Even break serious accident such as belt and carried out actv. prevention and control; Reduce the belt accident rate, effectively avoided the appearance of belt serious accident, guaranteed carrying out smoothly of safety in production; The 2nd, can intuitive judgment belt tension degree when carrying out work such as belt tension, defence belt tension tension and when producing, impact the accident of production; Reduced the input of the various material accessories that cause because of accident simultaneously, saved production cost, economic benefit is obvious.
