Abstract

The utility model provides a winch which is characterized in that the all diameters or part of diameters of the drum of the winch are different, and the variation can be discontinuous as well as continuous; the small-diameter part of the drum corresponds to the region having a requirement for low winching linear speed, generally a region in which operation just starts or nearly stops; and the large-diameter part of the drum corresponds to the operation region having a requirement for high winching linear speed and quickly running. The winch can realize different linear speeds in winching process by utilizing the varied diameter of the drum under the condition that the drum of the winch rotates at relatively constant speed. Accordingly, the winch meets the requirements of different running speeds in different regions such as winching starting, acceleration, high speed and deceleration, and meanwhile, meets the requirement for large traction force when the winch just starts. The winch is suitable for the fields with simple winching program and relatively fixed starting points, such as stereoscopic warehouses, stereoscopic garages, etc. The winch in the structure has the advantages of small cost investment, low running cost and high safety and reliability.

Description

A kind of winch
Technical field
The utility model relates to winch.
Background technology
Winch (being winch again) is a device of being finished traction work by mechanical powered drive reel, winch rope.Can vertical-lift, level or inclination drag and draw weight.The reel of existing winch all is cylindric, and reel diameter everywhere is equal substantially, and under the geostationary situation of the rotating speed of reel, pull wire speed also is geostationary.Therefore, in that trailed weight is at the early-stage maybe will stop the time, in order to alleviate being pulled the thing vibration and impacting, need slower linear velocity, prior art is that the rotating speed with reel reduces, and it mainly is to adopt method such as buncher that the rotating speed of reel is carried out speed governing.Because the cost input of speed governing system is bigger, fields such as, initial point relatively-stationary tiered warehouse facility simple, multi-storied garage for the elevator program, if still adopt speed governing systems such as buncher, so not only cost have high input, over-the-road expense height and the comparatively trouble of safeguard also.
Summary of the invention
The purpose of this utility model is that prior art is carried out useful replenishing, and a kind of winch is provided, and that cost drops into is little, over-the-road expense is low, safe and reliable.
The technical scheme that realizes the utility model purpose is: a kind of winch, reel are installed on the frame, and lift rope is wrapped on the reel, it is characterized in that the whole diameters or the section diameter of reel is unequal.The middle part equal diameters of reel, and the two-end part diameter of reel is less than the middle part.
The novel whole diameters or the section diameter of reel of utilizing of this reality is unequal, under the fixed condition of lifting drum rotating speed weighing apparatus, can realize different linear velocities in the elevator process, has satisfied the large traction demand when winch is at the early-stage simultaneously.The winch of this structure can not use the rotating speed speed governing system and realize the adjustment of linear velocity, is applicable to fields such as the elevator program is simple, the relatively-stationary tiered warehouse facility of initial point, multi-storied garage.
Description of drawings
Fig. 1 is the structural representation that the utility model relates to a kind of winch.
The specific embodiment
As shown in Figure 1, reel 2 is installed on the frame 1, and the middle a spot diameter of reel 2 S. A.s is big, and the two ends b point and the c spot diameter of reel 2 S. A.s are little, and lift rope 3 is wrapped on the reel 2.During work, reel 2 rotations.When the rotating speed of reel 2 was constant, because the drum diameter at b point place and c point place is little, the drum diameter at a point place was big, so,, that is to say when rotating speed at reel 2 is constant if use identical rotating speed, the linear velocity that lift rope 3 is ordered at b point and c is just slow, and the linear velocity that a order is just very fast relatively.In specifically executing, determine the length of lift rope 3 according to being pulled the weight operating range, according to starting, quicken, at a high speed, deceleration equal time and rate request, and drum speed, decide each position diameter on the reel, so just can form whole diameters or some position diameter is unequal reel 2.Do not need to be equipped with the rotating speed speed governing system, as under the drive of common electric machine, the rotating speed of reel 2 remains unchanged substantially, and then realizes the velocity variations of lift rope, has satisfied the big power demand when winch is at the early-stage simultaneously.

Claims (2)
