Abstract
The utility model relates to an overweight protective device of hoisting machine which is controlled wirelessly, belonging to the technical field of the hoisting machine safe protection. The utility model is to solve a technical problem of realizing overweight protection of the hoisting machine by adopting a wireless monitoring mode, meanwhile, the structure is simple and the measurement precision is high. A wireless overweight protector is connected on a section of steel rope between the top of suspension cage and the sliding wheel, and this protector is installed with a weighing sensor and a wireless emitter; the signal output end of the weighing sensor is connected with the signal input end of wireless emitter; a wireless receiver is installed in a control console, and the output end of the control signal is connected with the working coil of overweight protective relay. The utility model is used for overload protection of various hoisting and is especially applied for the elevator of construction site.
Description
Technical field
The utility model relates to elevator machinery security protection technology field, the overweight fender guard of especially a kind of elevator machinery of controlled in wireless.
Background technology
The overweight fender guard of existing a kind of elevator machinery is that load signal is passed to micro-switch, utilizes the normally closed contact of micro-switch to disconnect lifting control power circuit, prevents the lifting of lifting appliance overload thereby reach.This overweight fender guard structure is complicated, and it is not high that counterweight measures accuracy of measurement, and will link to each other with electric wire between micro-switch and the control desk, and this electric wire is followed weight-lifting equipment, does dipping and heaving as cage.This connecting wire is put because of its deadweight, by wind and cage is shed reason such as foreign material and made it to damage, and makes overweight protection lose load signal, and reliability closes, and unavoidable like this can the appearance caused all kinds of safety misadventures because of the cage load exceedance.
Summary of the invention
The technical problems to be solved in the utility model is: (1) adopts the controlled in wireless mode to realize the overweight protection of elevator machinery; (2) structure wants simple, survey precision is high.
The technical solution that the utility model proposed is such: the overweight fender guard of a kind of elevator machinery of controlled in wireless, cage 4 tops of this elevator machinery are connected with the cylinder of pulley 9 with hoisting crane 10 by steel rope 8, control desk 1 is equipped with bridge motor control major loop, be serially connected with wireless overweight protector 6 on one section steel wire rope 8 between described cage 4 tops and the pulley 9, LOAD CELLS 7 and wireless launcher 5 are housed in this protector 6, and LOAD CELLS 7 signal output parts are connected with wireless launcher 5 signal input parts; In described control desk 1 wireless receiver 3 is housed, overweight protective relay normally closed contact is serially connected in the bridge motor control major loop, and the control signal output ends of wireless receiver 3 is connected with described overweight protective relay working coil.Overload warning device 2 also is housed on the described control desk, and a normally open contact of its signal input part and overweight protective relay is connected.
Compared with prior art, the utlity model has following beneficial effect:
Because wireless monitoring technology is applied in the overweight fender guard of elevator machinery, thereby systematic survey and control accuracy height, scope are big, simple in structure, compact, and the reliability height has significantly reduced the various safety misadventures that cause because of the cage load exceedance.
The utility model is applicable to that various elevator machineries do overweight protection, is particularly suitable for the usefulness that pay in advance is made overload protection.
Description of drawings
Fig. 1 is embodiment of the utility model, a kind of elevator machinery of controlled in wireless is overweight fender guard structural representation.
The specific embodiment
By following embodiment the utility model is further elaborated.
The utility model is applied to the overweight fender guard structure of the building hoist of construction trade; referring to shown in Figure 1; the suspension ring of cage 4 and LOAD CELLS 7 lower ends tie with shackle, and its other end is fastened with steel rope 8, lie on the cylinder of hoisting crane 10 after passing pulley 9 again.And in control desk 1, a nothing is installed through line receiver 3 and overload warning device 2.When the goods of cage 4 deliveries surpasses the elevator rated load; voltage signal of output when the pulling force that the LOAD CELLS 7 in the wireless overweight protector 6 are subjected to is equal to or greater than the gravity of rated load; and by wireless launcher 5 emissions; wireless receiver 3 receives its signal; give overweight protective relay coil working from its mouth output control voltage then; the normally closed contact of this relay disconnects bridge motor control major loop; cage 4 stops lifting; and another open contact closure of relay; overload warning device 2; send chimes of doom; remind the operator to notice that the material in the cage 4 overloads; and after should taking corresponding loss of weight measure, could recover normal operation, thereby elevator is not suffered damage because of overload.When the goods of cage 4 deliveries does not surpass nominal payload; LOAD CELLS 7 in the wireless overweight protector 6 can not exported the overload voltage signal; at this moment; wireless receiver 3 is ready; can trigger action relay work, control desk 1 is working properly, and cage 4 and hoisting crane 10 are among the normal operation; ensured the safe operation of weight-lifting equipment, and improved its service life.
