Description
Technical field
The utility model relates to a kind of coaster with overload protection device of weighing, and belongs to handling machinery technical field.
Background technology
The tackle block of current application is mainly known or clearly for suspended object own wt, just can specify the specification of coaster, to realize the object of safty hoisting before lifting.But when coaster be used for the weight weight unknown that lifts really and be used for salvaging rescue time, just there will be overloading, there is potential safety hazard, for this reason, coaster is possessed weigh and overload protection function to promote the safety of tackle block, reliability is the task of top priority.
Utility model content
The utility model provides a kind of coaster with overload protection device of weighing.
The technical solution of the utility model is: a kind of coaster with overload protection device of weighing, comprise upper pulley, lower block, swivel joint, lever and pulling force sensor, described upper pulley is connected by steel rope with lower block, described lever and described upper pulley hinged, one end of described lever long end and described pulling force sensor is hinged, one end of the lever other end and described swivel joint is hinged, and described lever is the level of state, described pulling force sensor is vertical state, the other end and the described upper pulley of described pulling force sensor are hinged, the other end of described swivel joint is connected with one end of steel rope, the other end of steel rope is connected with winch, the pulling force data information obtained is sent to data processing module by described pulling force sensor, draw load data, if overload will be reported to the police.
Preferably, also comprise movable joint and hanging axis, described movable joint is connected with described upper pulley, and hanging axis is equipped with in described movable joint upper end.
Preferably, described lower block lower end is connected with shackle hook.
Preferably, also comprise lever postive stop baffle, described lever postive stop baffle is arranged on described upper pulley, and is positioned at described lever top position.
The beneficial effects of the utility model: coaster of the present utility model can directly read suspended object weight in hoisting process, in addition, this coaster in use can carry out examination to the true object of suspended object weight unknown and hang, and has overload warning function, avoid overload to damage coaster, reduce the loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model with the coaster of overload protection device of weighing;
Fig. 2 is the lateral plan of Fig. 1;
Fig. 3 is that the utility model is weighed overload protection device workflow diagram;

Detailed description of the invention
By reference to the accompanying drawings the embodiment that the utility model provides is described in further detail:
As Fig. 1, shown in 2, a kind of coaster with overload protection device of weighing, comprise upper pulley 3, lower block 9 and overload protection device of weighing, described upper pulley 3 is connected by steel rope 8 with lower block 9, overload protection device of weighing comprises swivel joint 7, lever 5, lever postive stop baffle 4 and pulling force sensor 6, described lever 5 is hinged with described upper pulley 3, one end of described lever 5 long end and described pulling force sensor 6 is hinged, one end of lever 5 other end and described swivel joint 7 is hinged, and described lever 5 is the level of state, described pulling force sensor 6 is in vertical state, the other end and the described upper pulley 3 of described pulling force sensor 6 are hinged, the other end of described swivel joint 7 is connected with one end of steel rope 8, the other end of steel rope 8 is connected with winch 10, described lever postive stop baffle 4 is arranged on described upper pulley 3, and be positioned at described lever 5 top position, lower block 9 lower end is connected with shackle hook 11.
In the present embodiment, also comprise movable joint 2 and hanging axis 1, described movable joint 2 is connected with described upper pulley 3, and hanging axis 1 is equipped with in described movable joint 2 upper end.
Working process of the present utility model: after shackle hook 11 and suspended object connect, winch 10 hoisting rope, lifting heavy, steel rope 8 stress load increases, this power is by swivel joint 7, lever 5 is proportional reaches pulling force sensor 6, pulling force sensor 6 produces number range between the 4-20mA dynamically continuous equivalent or value data signal that moves within narrow limits, the feedway of this signal in pulling force sensor 6 reaches the signal receiving device in weight-lifting equipment operator's compartment, receiving device will send into plc data processing module after signals revivification, through computing output overloading alerting signal or payload data, payload data shows, realize load monitoring and load-carrying accumulative (as shown in Figure 3).
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
