Abstract
The invention provides a speed reducer for a lifting device, which integrates three functions of overload protection, travel control and manual input into one whole body. A safety load is set by regulating a screw; when an output torque exceeds the set safety load, a worm axially moves to squeeze a spring and a spring sleeve touches and controls an overload protection safety switch to stop outputting; when an output shaft of the speed reducer for the lifting device is lifted or descended to a set travel position, a stop lever on a screw rod touches the travel control switch to implement functions of stopping outputting, reversely outputting or outputting in a decelerated manner and the like; under the condition of power failure or under other specific conditions, a machine cannot be driven and lifting equipment can be manually driven by a hand crank.
Description
Technical field
The present invention relates to a kind of lifting device speed reducer, is a kind of Stroke Control that has, the lifting device speed reducer of torque overload protection and manual drives function.
Background technique
Lifting device speed reducer has deceleration and increases torque functions, in the transmission system of various machinery, is widely used.It has many advantages such as compact structure, easy for installation, long service life.There is following problem in common lifting device speed reducer: when overload work, easily causes driving mechanism and operation mechanism's damage, greatly reduce working life; There is no effective travel control device, can not circular flow, and lift stroke is accurate not, and reliability is not high; Can not normal operation under power-off or specified conditions.The disclosed novel overload protection arrangement of patent No. CN200720148982.4 and electric chain hoister thereof, be to utilize slip gear, and the frictional force of utilizing spring extruding to produce maintains transmission.This structure can not be set output loads, has narrow limitation; The disclosed lifting gear travel control device of patent No. CN200910266197.2, lift and corresponding controlling method are to utilize counter and encoder feedback signal to control stroke to controller.Its control procedure is more complicated, high expensive; The disclosed a kind of hand hoisting device of patent No. CN201020607277.8, is manually inputted by two half-coupling connecting handles, needs manually to connect two half-couplings and could realize manually input, and this structure is relatively loaded down with trivial details; Above three kinds of lifting device speed reducers all can not realize simultaneously overload protection, manually input and stroke control function.
Summary of the invention
The object of the present invention is to provide a kind of have overload protection, manually input and the lifting device speed reducer of stroke control function simultaneously.
Technical solution of the present invention is:
A kind of lifting device speed reducer; comprise and promote gear worm lifting decelerator, lifting motor, main driving worm-gear speed reducer, screw mandrel and output shaft; lifting motor connects lifting worm-gear speed reducer; promote worm gear and the screw mandrel engagement of worm-gear speed reducer; screw mandrel bottom connects output shaft; output shaft is connected to the worm gear of main driving worm-gear speed reducer through spline, described lifting device speed reducer is provided with travel control device; The worm screw of described main driving worm-gear speed reducer connects overload protection safety installations; Described lifting gear worm speed reducer is provided with wind.
Further, described travel control device comprises upper stroke switch, lower stroke switch and pin, and pin is connected on screw mandrel, and pin touches the state of upper stroke switch and lower stroke switch while being difference between upper stroke switch and lower stroke switch.
Further; described overload protection safety installations comprises adjusting screw, spring, spring housing and Overload Protection switch; spring one end connects adjusting screw; spring the other end linking springs cover; spring housing is axially connected in the worm screw main shaft of main driving worm-gear speed reducer, and spring housing and Overload Protection switch are and contact or contact condition not.
Again further, described wind is axially connected in the worm screw that promotes worm-gear speed reducer.
Take after above technological scheme, the beneficial effect that the present invention reaches is:
(1) can set safe load by adjusting screw rod, when output torque surpasses the safe load of setting, worm screw generation axial displacement extrusion spring.Spring housing touch-control overload protection safety switch, output stops.Therefore speed reducer always works under safe load, be improved working life.
(2) when the output shaft of lifting device speed reducer is elevated to the travel position of setting, the pin on screw mandrel touches travel control switch, realizes and stops, oppositely exporting or the functions such as output of slowing down.Utilize Stroke Control can more accurately control lifting displacement.
(3) under power-off or other particular cases, machine cannot drive, and can utilize wind manual drives jacking equipment, and purposes is more extensive.
