Description

A kind of finishing carrying implement

Technical field

The present invention relates to be a kind of applicable house decoration the time carrying heavy goods carrying implement.

Background technology

In the existing house decoration process, carrying heavy goods is generally undertaken by pulley gear, pulley gear has manual drive and motor drive mode, hand-driven pulley gear shortcoming is a lot, motor-driven pulley gear is obviously laborsaving, but also there is larger shortcoming, 1. the rising of weight and decline all need actuating motor to finish, weight rises and can play the labour-saving effect take motor as power, motor was no-load run when but weight descended, the adverse consequences of empty load of motor operation is that motor generates heat easily, and motor is short service life, and reactive power consumption is large; 2. slow by motor-driven weight descending speed, the weight descending speed is close with the weight ascending velocity, and efficient is low.

Summary of the invention

Carrying heavy goods when technical matters to be solved by this invention provides a kind of applicable house decoration, the finishing carrying implement with the advantage such as energy-conservation, that efficient is high, electrical machinery life is long.

The present invention implements by following technical solution:

A kind of finishing carrying implement, it is characterized in that: comprise the braking motor retarder, reel, drum shaft and permanent seat, drum shaft rotatably arranges, the left end of drum shaft is connected with the mouth of braking motor retarder, right-hand member is provided with power-transfer clutch, power-transfer clutch is comprised of halfbody A and halfbody B, halfbody A slides and is located on the drum shaft, halfbody A is provided with fork slot, fork slot is stirred by the shift fork of shifting fork mechanism, halfbody B empty set is located on the drum shaft captives joint with reel, and the clutch tooth back of tooth of halfbody A and halfbody B is the inclined-plane, and described reel passes through the bearing pivoting support on drum shaft.Finishing carrying implement provided by the invention, at the weight ascent stage, motor power can be delivered to reel by power-transfer clutch makes reel rotate the rising of drive weight, and in the weight decline stage, power-transfer clutch can automatically switch to disengaged condition, so reel freely rotates, under the out-of-run state of motor, can realize the fast-descending of weight.

Described reel right side end plate is provided with speed controller, speed controller comprises brake ring, fulcrum, cam and retracing spring, brake ring can be opened or close up, the annular friction face that brake ring had when brake ring was opened contacts with the inner headed face of reel right side end plate, brake ring is comprised of two brake semi-rings, two brake semi-rings are take fulcrum as a spot wobble setting, fulcrum is located on the permanent seat, cam rotatably arranges between the folding end of two brake semi-rings, cam is connected with speed control handle, and described retracing spring is connected on two brake semi-rings the tension of two brake semi-rings.For avoiding the weight descending speed too fast, the present invention is provided with the velocity of rotation that speed controller is controlled reel, principle of work is: pull speed control handle cam is rotated, cam working face after the rotation leans two brake semi-rings opens brake ring, the annular friction face that brake ring has contacts with the inner headed face of reel right side end plate, reel is applied friction drag, thereby reach the purpose of control weight descending speed.

Described shifting fork mechanism comprises clutch handle, shift fork and torsion spring, the setting that swings of the permanent seat of clutch handle outside the end plate of described reel right side, the bottom moved end of clutch handle is connected with the fixing shifting fork bar of shift fork, one of described torsion spring is connected to the bottom moved end of clutch handle, the other end is connected on the torsion spring seat, torsion spring seat fixedly mounts at permanent seat, and under the effect of torsion spring power, clutch handle can rest on after pulling to be pulled the position and prevent from automatically returning.In the said mechanism, because the existence of torsion spring, must apply the resistance that certain power overcomes torsion spring at clutch handle and could realize disengagement and the combination of power-transfer clutch, thereby preventing that the external factors such as power-transfer clutch is vibrated are disturbed in the carrying heavy goods process produces misoperation.

The specific embodiment

Describe details and the principle of work of the specific embodiment of the invention in detail below in conjunction with accompanying drawing:

As shown in the figure, finishing carrying implement of the present invention, comprise braking motor retarder 1, reel 2, drum shaft 3 and permanent seat 14, drum shaft 3 rotatably arranges, the left end of drum shaft 3 is connected with the mouth of braking motor retarder 1, right-hand member is provided with power-transfer clutch, power-transfer clutch is comprised of halfbody A and halfbody B, halfbody A slides by the endoporus spline and is located on the drum shaft 3, halfbody A can be free to slide in drum shaft but can not relatively rotate, halfbody A is provided with fork slot, and fork slot is stirred by the shift fork 4 of shifting fork mechanism, and halfbody B empty set is located on the drum shaft 3 captives joint with reel 2, the clutch tooth back of tooth of halfbody A and halfbody B is the inclined-plane, described reel 2 passes through the bearing pivoting support on drum shaft 3, when direction of drum shaft is rotated the mutual interlock of clutch tooth of halfbody A and halfbody B, drum shaft band movable reel rotates, when the rotation of drum shaft opposite sense, the clutch tooth of halfbody A and halfbody B is thrown off mutually, and drum shaft can not be with movable reel to rotate; Described reel right side end plate 2a is provided with speed controller, speed controller comprises brake ring (being comprised of two brake semi-rings 6), fulcrum 8, cam 13 and retracing spring 15, brake ring can be opened or close up, the annular friction face that brake ring had when brake ring was opened contacts with the inner headed face of reel right side end plate 2a, two brake semi-rings 6 are take two fulcrums 8 as a spot wobble setting, fulcrum 8 is captiveed joint with permanent seat 14, cam 13 rotatably arranges between the folding end of two brake semi-rings 6, cam 13 is connected with speed control handle 12, and described retracing spring 15 is connected on two brake semi-rings 6 tension of two brake semi-rings; Described shifting fork mechanism comprises clutch handle 7, shift fork 4 and torsion spring 11, setting swings take bearing pin 9 as fulcrum on the permanent seat 14 of clutch handle 7 outside the end plate of described reel right side, the bottom moved end of clutch handle 7 is connected with the fixing shifting fork bar 5 of

shift fork

4,11 1 of described torsion springs are connected to the bottom moved end of clutch handle 7, the other end is connected on the torsion spring seat 10, torsion spring seat 10 is in permanent seat 14 fixed installations, under the effect of torsion spring power, clutch handle 7 can rest on after pulling to be pulled the position and prevents from automatically returning.

The present invention is like this work: when the needs lifting heavy, shift clutch handle 7 onto Fig. 1 state position, the power-transfer clutch combination, then actuating motor, motor power can be delivered to reel by power-transfer clutch makes reel 2 rotate the rising of drive weight, when needs put down weight, as long as the crawl motor makes motor reversal, power-transfer clutch automatically switches to disengaged condition (certainly can directly make throw-out-of clutch with the hand propelled clutch handle), so reel 2 freely rotates, under the out-of-run state of motor, realize the fast-descending of weight; For avoiding the weight descending speed too fast, pulling speed control handle 12 rotates cam 13, cam after the rotation can make brake ring open, the annular friction face that brake ring has contacts with the inner headed face of reel right side end plate 2a, reel 2 is applied friction drag, thereby reach the purpose of control weight descending speed, put on the power of speed control handle by control, can reasonably regulate the weight descending speed easily.
