Description
Technical Field
The utility model relates to belt winding type lifting equipment, in particular to a unbalanced belt breakage detection mechanism used in the belt winding type lifting equipment.
Background
In the belt winding type lifting equipment, a belt is used as a force transmission medium to complete corresponding lifting and reciprocating actions; in each action cycle, the belt will undergo two operating conditions, namely a winding condition and a winding release condition; in the winding state of the belt, if a certain belt does not work, the belt is likely to break; in the belt winding release state, if a certain belt does not work, the belt possibly breaks, or the belt side is accidentally blocked to cause the phenomenon of belt loosening; if the abnormal state of the belt can not be detected in time and the belt is stopped, alarming and asking for help, serious damage to equipment can be caused, and even serious safety accidents are caused; the existing belt breakage or belt loosening detection method generally adopts a travel switch direct detection method, namely a deflector rod roller of the travel switch directly abuts against a running belt, and when the belt is in a belt loosening and belt breakage state, the deflector rod roller swings back to trigger a belt breakage detection switch to send out a belt breakage signal; in the detection mode, the diameter of the deflector rod roller is smaller, the detected belt drives the deflector rod roller to rotate at high speed, the defect that a switch is easy to damage exists, and in addition, the switch can send an alarm signal by mistake due to the fact that the roller jumps at an excessive speed; how to overcome the above defects becomes a problem to be solved in the field.
Disclosure of Invention
The utility model provides a weight-bias type broken belt detection mechanism used in belt hoisting type lifting equipment, which solves the technical problems that a switch is easy to damage and false alarm is easy to occur in the existing travel switch direct detection method.
The utility model solves the technical problems by the following technical proposal:
the utility model provides a disconnected area detection mechanism of unbalance weight formula that uses in belt hoist formula jacking equipment, including belt hoist formula equipment support, be provided with the belt pulley of belt power on the left side facade of the stand lower extreme of belt hoist formula equipment support, be provided with the belt steering wheel on the stand top of belt hoist formula equipment support, be provided with the hoist belt between belt pulley and belt steering wheel, be provided with the round pin axle at the stand middle part of belt hoist formula equipment support, it has the V-arrangement swing arm to articulate at the round pin axle, be connected with the rubber running roller at the left end of V-arrangement swing arm, the rubber running roller top is connected with on the right flank of hoist belt, and, the hoist belt provides a side downward pressure for the rubber running roller, be connected with the counter weight roller at the right-hand member of V-arrangement swing arm, be provided with trigger switch on the middle part crossbeam of belt hoist formula equipment support on counter weight roller right side, trigger pendulum rod contact setting is in the right side below of counter weight roller.
An adjusting nut is arranged at the right part of the V-shaped swing arm, an adjusting screw is connected in the adjusting nut in a threaded manner, and the lower end of the adjusting screw is arranged above a middle cross beam of the belt hoisting type equipment bracket; the length of the rubber roller is greater than the width of the hoisting belt.
The utility model overcomes the defect that the traditional trigger switch roller is easy to generate over-speed jump so as to send an alarm signal by mistake, and the broken belt detection is sensitive and reliable; and the detection sensitivity can be dynamically adjusted through the matching of the adjusting nut and the adjusting screw.

FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic structural view of the V-shaped swing arm 6 of the present utility model.
Description of the embodiments
The utility model is described in detail below with reference to the attached drawing figures:
the utility model provides a disconnected area detection mechanism of unbalance weight formula that uses in belt hoist formula lifting device, including belt hoist formula equipment support 1, be provided with belt winding wheel 2 with power on the left side facade of the stand lower extreme of belt hoist formula equipment support 1, be provided with belt steering wheel 3 on the stand top of belt hoist formula equipment support 1, be provided with hoist belt 4 between belt winding wheel 2 and belt steering wheel 3, be provided with round pin axle 5 at the stand middle part of belt hoist formula equipment support 1, it has V-arrangement swing arm 6 to articulate on round pin axle 5, be connected with rubber roller 7 at the left end of V-arrangement swing arm 6, rubber roller 7 top is on hoist belt 4's right flank, and, hoist belt 4 provides a side down force for rubber roller 7, be connected with counter weight roller 8 at the right-hand member of V-arrangement swing arm 6, be provided with trigger switch 9 on the middle part crossbeam of belt hoist formula equipment support 1 on counter weight roller 8 right side, trigger switch 9 trigger pendulum contact 10 sets up in counter weight roller 8's right side.
An adjusting nut 11 is arranged at the right part of the V-shaped swing arm 6, an adjusting screw rod 12 is connected in the adjusting nut 11 in a threaded manner, and the lower end of the adjusting screw rod 12 is arranged above the middle cross beam of the belt hoisting type equipment bracket 1; the length of the rubber roller 7 is greater than the width of the hoisting belt 4.
The V-shaped swing arm 6 is hinged on the pin shaft 5, and the balance weight roller 8 is heavier, so that the V-shaped swing arm 6 rotates clockwise, but when the rubber roller 7 is propped against the inner side surface of the hoisting belt 4 in rotation, the hoisting belt 4 in the collapse operation forms lateral downward pressure on the rubber roller 7, the moment formed by the lateral pressure and the lower swing moment formed by the balance weight roller 8 on the V-shaped swing arm 6 are balanced with each other, the balance weight roller 8 is positioned right above the trigger swing rod contact 10, and the trigger switch 9 is in an un-triggered state; if the winch belt 4 in the collapse operation breaks off, the side downward pressure of the winch belt 4 to the rubber roller 7 disappears, the weight of the counterweight roller 8 enables the V-shaped swing arm 6 to rotate and swing clockwise, the counterweight roller 8 is in contact with the trigger swing rod contact 10, the trigger switch 9 is triggered, and an alarm signal is sent; the touch time of the counterweight roller 8 and the trigger swing rod contact 10 can be adjusted by rotating the adjusting screw 12 in the adjusting nut 11, so that the multi-angle reliable triggering of the detection mechanism under various conditions is ensured.
