Abstract
The invention provides a belt breakage preventing overload protective system for a belt lifter. The belt breakage preventing overload protective system comprises a belt, a belt clip, a connecting bolt, a supporting frame, a stud, a support and an alarm system. The system is directly connected with the belt and capable of directly utilizing the stress on the belt, and therefore, the load of the belt can be determined; besides, a sliding rod is driven by the belt to slide to compress a spring and a disc spring, and if different stresses are applied to the belt, the compression degrees of the spring and the disc spring are different, and consequently, the positions of a positioning block are changeable and working state grooves I and II formed in the positioning block are in contact with different travel switches, and therefore, the load conditions of the belt can be reflected immediately and accurately and accidents can be avoided.

Yet existing belt be all by people for watching, whether surpass rated load, error is large especially, thereby and is often out of one's reckoning mutually accidents caused.
Summary of the invention
While the object of the invention is for solution belt broken belt or overload, cannot find in time and detect problem not in time, anti-broken belt overload protective device for a kind of belt lifting machine is provided, this system is by being directly connected with belt, the power that can directly utilize belt to be subject to, thereby formulate its load, and slide by belt band moving slide-bar, pressuring spring and dish spring, belt is subject to different power, will make spring and dish spring level of compression different, the position that makes locating piece is in diverse location, the mode of operation groove I offering on it can contact from different travel switches with II, thereby can be in time and react accurately the load condition of belt, avoid the generation of accident.
The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
Anti-broken belt overload protective device for a kind of belt lifting machine, comprise belt, belt clamp, tie bolt, holding frame, double end stud, support and warning, described strap end is bolted on one end of belt clamp, the other end of belt clamp is connected with holding frame by tie bolt, double end stud is installed on holding frame, on described support, slidably connect slide bar, slide bar one end is connected with double end stud, setscrew nut is installed on the other end, on slide bar, between self-align nut and support, be arranged with successively from top to bottom locating piece, spring and dish spring, between spring and dish spring, be provided with a spacer sleeve, one end of spring is fixed on locating piece, the other end compresses dish spring by spacer sleeve, spacer sleeve is supported in dish spring one end, the other end is connected on support, on locating piece, offer mode of operation groove I and mode of operation groove II, on support, by strut bar, be connected and installed with travel switches I and travel switches I I, by the stressed variation band of belt moving slide-bar, sliding up and down pressuring spring contacts with travel switches I I with control travel switches I with mode of operation groove II with dish spring control locating piece mode of operation groove I, travel switches I is all connected with warning with travel switches I I, this warning is conventional warning device, when forming switch I action, having the emergency alarm bell sound rises, and bright by warning light, form the tinkle of bells and display lamp action that switch I I action has cooperation simultaneously.
Described dish spring is connected with support by sliding sleeve.
Described strut bar is fixed on support by pedestal.
The invention has the beneficial effects as follows: this system is by being directly connected with belt, the power that can directly utilize belt to be subject to, thereby formulate its load, and slide by belt band moving slide-bar, pressuring spring and dish spring, belt is subject to different power, will make spring and dish spring level of compression different, the position that makes locating piece is in diverse location, the mode of operation groove I offering on it can contact from different travel switches with II, thereby can be in time and react accurately the load condition of belt, avoid the generation of accident.
