Limit switch also known as travel switch, for controlling stroke and the position limitation protection of mechanical equipment.In actual production, travel switch is arranged on prearranged position, when being loaded on the module impact stroke switch on manufacturing machine movable parts, the contact action of travel switch, the switch of realizing circuit or switching.Travel switch be a kind of according to the travel position of movable parts the electrical equipment of commutation circuit, its action principle and button similar.Travel switch is widely used in all kinds of lathe and elevator machinery, in order to control its stroke, to carry out terminal position limitation protection.
Overhead traveling crane has the advantage that structure is simple, easy to maintenance, hoisting capacity greatly, does not take up an area face working area, not only alleviates the manual labor of workman, can also enhance productivity, so it is widely used in commercial production; But easily there is de-groove fault because ongoing operations uses, if operating personal can not Timeliness coverage withdraw from use, the length of steel rope time of overhead traveling crane can be caused to take off groove and use, will the fault such as damage, fracture of steel rope, assembly pulley be caused; More serious, cause serious accident by due to steel rope, dropping of assembly pulley.
Utility model content
The utility model technical issues that need to address are to provide a kind of overhead traveling crane warning steel cable slot disengaging, when steel rope comes off from fixed pulley groove, power-off can be carried out in time, and remind staff to get rid of fault, avoid the damage of steel rope, pulley, operational security improves greatly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of overhead traveling crane warning steel cable slot disengaging, the fixed pulley comprise crane carriage, arranging between the vehicle frame of crane carriage, the top of fixed pulley is provided with hook housing, described hook housing comprises cross bar and the vertical pole of several welding edges on cross bar, the afterbody of vertical pole is provided with the crotch for hook steel rope, and each fixed pulley both sides are respectively provided with a crotch bent to fixed pulley; Described vehicle frame is provided with the hook housing limit switch be connected with the lifting position-limit switch of overhead traveling crane, hook housing limit switch connects warning device; The two ends of cross bar are overlapped on hook housing limit switch.
The further improvement of technical solutions of the utility model is: described crane carriage is provided with angle bar, and hook housing limit switch is fixedly connected with the vehicle frame of crane carriage by angle bar.
The further improvement of technical solutions of the utility model is: described warning device is connected with the lighting circuit of electric mechanism.
The further improvement of technical solutions of the utility model is: described hook housing limit switch is two, is symmetricly set on the vehicle frame of pulley both sides.
The further improvement of technical solutions of the utility model is: the crotch of vertical pole afterbody and the distance of fixed pulley are less than the diameter of steel rope.
The further improvement of technical solutions of the utility model is: the crotch of vertical pole afterbody and the distance range of fixed pulley are between 0 to 15 millimeters.
Owing to have employed technique scheme, the technological advance that the utility model obtains is:
A kind of overhead traveling crane warning steel cable slot disengaging of the present utility model, when steel rope comes off from fixed pulley groove, can carry out power-off in time, and remind staff to get rid of fault, avoid the damage of steel rope, pulley, operational security improves greatly.
Steel rope in fixed pulley groove in crown sheave group probably comes off in the process run from groove, and the utility model installs hook housing additional above groove, and hook housing connects hook housing limit switch, and hook housing limit switch is connected with the lifting position-limit of overhead traveling crane electric mechanism.When steel rope comes off from groove, steel rope pulls hook housing to sink, and hook housing touches hook housing limit switch, cuts off the power plant power supply of overhead traveling crane, prevents the damage such as steel rope, pulley, avoid the accident because steel cable slot disengaging may cause; Hook housing limit switch is also connected with warning device, warning device is power taking from lighting circuit, when cutting off overhead traveling crane power plant power supply, warning device normally works, when steel rope comes off shake-up warning device from groove, warning device sends sound and light alarm, reminds staff to get rid of steel cable slot disengaging fault in time, safe operation.
Hook housing limit switch is symmetrical arranged on the both sides, vehicle frame of fixed pulley, and no matter steel cable slot disengaging drops to which side of fixed pulley, can both touch and touch hook housing limit switch by hook housing, and then reports to the police.The crotch of vertical pole afterbody and the distance of fixed pulley side are less than the diameter of steel rope, during to ensure that steel cable slot disengaging drops, can fall in crotch, affect hook housing, trigger hook housing limit switch.
