Abstract

The utility model provides a winding engine driven by hands or electric power, which can use a hand-operated device to continuously host and install goods or equipment to be hoisted through engaging and disengaging when power is suddenly cut off. An electric motor 1 in the winding engine driven by hands or electric power is connected with a main axle 5 through a clutch 3, the outward extending end of a speed reducer 6 is provided with a gear 8, a reel 4 is supported on the main axle 5 through a bearing, and the gear 8 is engaged with an inner gear of the left end of the reel 4. The utility model is characterized in that a high-speed axle of the speed reducer 6 is a double-extending axle, the extending end of a right-end axle is connected with a handle 7 through a key, and the handle is axially fixed on the main axle 5.

Description

Winding engine driven by hand or electric power

The utility model belongs to building whim, is a kind of manual below 1 ton and 1 ton, electronic volume field machine specifically.

At present, building whim below 1 ton and 1 ton has (JK) and (JM) two series fast at a slow speed, and the lifting or the equipment that are mainly used in goods below 1 ton and 1 ton are installed.Its type of belt drive is electrical motor---coupler---drg---retarder---volume simple device, it is electronic, automatically controlled that working forms is, and when unexpected power failure, the goods that is hung (as floor, machinery and equipment etc.) can only be parked in the space, very dangerous, have only the incoming call of wait.When unexpected incoming call, motor hurriedly starts, and the goods vibration beat that is hung is big, dangerous big, and particularly the rural area power failure is frequent, makes troubles for building lifting, installation.

The purpose of this utility model then is the problem at above-mentioned existence, provides a kind of when unexpected the power failure, can continue goods that is hung or equipment with manual unit manual, the electric winch below 1 ton and 1 ton of lifting, installation by clutch.

The utility model technical solution:

A kind of manual, electric winch below 1 ton and 1 ton, wherein electrical motor 1 links by power-transfer clutch 3 and main shaft 5, retarder 6 overhanging ends are equipped with gear 8, reel 4 is bearing on the main shaft 5 by bearing, gear 8 is meshed with reel 4 right-hand member inner geares, it is characterized in that retarder 6 high speed shafts are two shafts, right-hand member shaft extension end links by key and handle 7, and handle 7 is axially fixed on the main shaft 5.

The utility model has following advantage compared to existing technology:

In vast rural area, outlying mountain area, district newly developed, on the ship, place short of electricity such as forest or when having a power failure, the utility model can solve the lifting, installation, dilatory etc. of goods below 1 ton and 1 ton by manual unit.Improved farm building troop family widely and chosen the backward situation that the people shoulders, had the electric energy lifting to install, having a power failure also can work on, and safe and reliable.

Fig. 1 is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model is further described:

Electrical motor 1 is the Cone-shaped electric machine of band brake, its tie-plate links by bolt and support 2, the shaft extension end of electrical motor 1 links by power-transfer clutch 3 and main shaft 5, main shaft 5 left ends are bearing on the support 2 by bearing, and main shaft 5 right-hand members are gear wheel shaft, and gear wheel shaft links by the casing of bearing and retarder 6, and with the casing right-hand member supporting support, the high speed shaft of retarder 6 and main shaft 5 unite two into one, and its slow-speed shaft overhanging end links with key and gear 8, and gear 8 is meshed with reel 4 right-hand member inner geares.When electricity was arranged, power-transfer clutch 3 closed, and transmission of power is: electrical motor 1---power-transfer clutch 3---main shaft 5---retarder 6 high speed shafts---retarder 6 slow-speed shafts---gear 8---reel 4 right-hand member inner geares---reel 4.After the power failure, cut off motor power, its transmission of power is: people's (manually), and------retarder 6 high speed shafts are by gear mesh retarder 6 slow-speed shafts, and---gear 8---reel 4 right-hand member inner geares---reel 4 drives reel 4 and rotates handle 7, guarantees that goods hoists or descends.

Claims

1, a kind of manual, electric winch below 1 ton and 1 ton, wherein electrical motor (1) links by power-transfer clutch (3) and main shaft (5), retarder (6) overhanging end is equipped with gear (8), reel (4) is bearing on the main shaft (5) by bearing, gear (8) is meshed with reel (4) right-hand member inner gear, it is characterized in that retarder (6) high speed shaft is two shafts, right-hand member shaft extension end links by key and handle (7), and handle (7) is axially fixed on the main shaft (5).
