Abstract
The invention discloses a lifting hook limiting device applied to hoisting machinery. The lifting hook limiting device comprises a shell, a motor, a limiting rod and a rope guide, wherein one end of the shell is fixedly connected with the motor; a limiter is arranged at the interior of the motor; one end of the limiter is fixedly connected with one end of the limiting rod; the other end of the limiting rod stretches into the other end close to the shell in the shell; a baffle a and a baffle b are arranged at two ends of the limiting rod respectively; the rope guide is arranged between the baffle a and the baffle b; a winding drum is arranged at the bottom of the shell; two ends of the winding drum are fixedly connected with two ends of the shell through a coupler a and a coupler b respectively; a limiting switch is arranged above the winding drum. The lifting hook limiting device has the beneficial effects that the structure is simple, the objects are lifted by a pulley block structure; the time is saved; the labor is saved; the condition that the device stops working due to failure of a potentiometer can also be avoided; the couplers are connected with the winding drum, the vibration can be effectively reduced; meanwhile, nuts and bolts are used for fixing the baffles on the limiting rods; the phenomenon that the baffles move by virtue of reciprocating movement of the rope guide is avoided; the unnecessary economic loss is avoided; the lifting hook limiting device is relatively stable in operation process and high in safety.
Description
Technical field
The present invention relates to a kind of suspension hook limit device for elevator machinery.
Background technology
Elevator machinery manufacturing development in recent years rapidly, uses elevator machinery to have the huge market demand and good economy, elevator machinery, refer to for
verticallylifting or vertical lift the electromechanical appliance of parallel motion weight, main task completes hoisting operation exactly, and hoisting operation is that mechanical equipment or other objects are transported to the industrial process of another place from a place, and most elevator machinery exists
suspendernamely the forced stroke vertically or vertically having level concurrently is started, after arriving destination after feeding
unloading, then idle travel is to feeding place, completes a working cycle, and then carries out second time handling.
In general, during elevator machinery work, feeding, migration and unloading are carried out successively, and the work of each corresponding mechanism is intermittent, and the suspension hook limit device in elevator machinery is mainly used in carrying work piece, can carry after being equipped with grab bucket
coal,
ore,
grainand so on bulk material, be equipped with that contain after bucket can handling molten steel etc.
liquidmaterial, its principle of work is: elevator machinery is hoisted by suspension hook limit device or hoisted and adds moving heavy object, suspension hook limit device is mentioned weight from getting thing place by suspension hook, through operation, revolution or luffing mechanism, weight is shifted, original position is turned back to after weight is transferred in appointed place, but less stable in traditional suspension hook limit device operational process, rope guide easily moves around, often there is the phenomenon be shifted in baffle plate, thus cause suspension hook limit device to lose efficacy, cause unnecessary loss, and easily safety misadventure occurs, safety is lower.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, the suspension hook limit device for elevator machinery of good stability.
The technical solution adopted in the present invention is:
A kind of suspension hook limit device for elevator machinery, comprise housing, motor, position-limited lever and rope guide, described shell one end is fixedly connected with motor, described motor internal is provided with limiting device, described limiting device one end is fixedly connected with position-limited lever one end, the described position-limited lever other end puts in enclosure interior near the housing other end, described position-limited lever two ends are respectively equipped with baffle plate a and baffle plate b, described rope guide is located between baffle plate a and baffle plate b, described housing bottom arranges reel, described reel two ends are fixedly connected with housing two ends respectively by coupler a with coupler b, limit switch is provided with above described reel.
Described reel connects assembly pulley by steel rope, and described assembly pulley comprises a pulley and two weights.
Described assembly pulley is fixedly connected with suspension hook by steel rope.
Described baffle plate a comprises nut a and bolt a, and described baffle plate b comprises nut b and bolt b.
The invention has the beneficial effects as follows: structure is simple, pulley block structure is adopted to get thing both time saving and energy saving, can avoid again causing the out-of-work situation of equipment because potential device lost efficacy, use coupler to connect reel and can reduce vibrations by actv., use nuts and bolt to be fixed on position-limited lever by baffle plate simultaneously, avoid rope guide to move around and cause baffle plate that the phenomenon of displacement occurs, thus avoid unnecessary economic loss, and operational process is more stable, safety is higher.
