Description
Technical field
The utility model relates to multi-rope friction hoisting machine fields more particularly to a kind of tower multi-rope friction hoisting machine to look for
Positive anti-deflection device.
Background technique
Multi-rope friction hoisting machine is widely used in the industries such as coal, non-ferrous metal, ferrous metal, nonmetallic, chemical industry
To promote mineral, lifts personnel and material and equipment etc. in lifting system, it also can be used as other traction transporting equipments and use.
Multi-rope friction hoisting machine uses flexible body frictional drive principle, and wirerope is centered around on friction pulley, utilizes wirerope and friction
Frictional force between liner causes on reel to promote lower section weight or personnel, the wirerope-winding for solving cylindrical drum hoist
Reel is relatively large in diameter, and is restricted the promotion speed of elevator and efficiency, and the number of bends of wirerope more causes
The problem of operating condition of wirerope is poor, makes the service life reduction of wirerope.
The arrangement of multi-rope friction equipment can be divided into tower and two class of console mode.The frictional mine of ground-type multi-cable
On the ground, wirerope introduces in well after passing through the deflecting of day wheel system and is connected with hoisting container the main body arrangement of elevator, though
Right derrick is low and facilitates installation, but because having used day wheel system, and the number of bends for increasing wirerope reduces making for wirerope
With the service life, and increase cost.The main body of tower multi-rope friction type mine hoist is arranged in headframe top tower, wirerope
Both ends naturally droop and fall into well from friction pulley, compact-sized province and to be not exposed to wirerope outdoor, make wirerope
Possess preferable working environment and increase rope service-life, but because wirerope naturally droops, it is difficult to solve to wear because of lining pad
And the reasons such as steel rope abrasion and the promotion sideslip problem that generates, and in order to solve the problems, such as sideslip, existing common methods are
Guiding head sheave is added below the main drum of tower multi-rope friction type mine hoist to carry out centering and guiding to wirerope, but
Adding guiding head sheave can make wirerope generate back-flexing, influence the service life of wirerope, also make Structure of hoist complicated, at
This increase；Meanwhile there are also the prior arts, and fixed mechanical structure is arranged around wirerope, such as limit rope, limit
Block, spacing collar etc., be in contact with it wirerope can when sideslip occurs, and prevent sideslip with this to limit the displacement of wirerope,
But doing so can make wirerope during lifting and the contact of the mechanical structure of above-mentioned fixation and friction and wear occurs, both shadow
The lifting for ringing wirerope can also reduce the service life of wirerope.
Utility model content
The purpose of this utility model is to solve above-mentioned problem of the prior art, provides a kind of tower multi-rope friction hoisting machine
From centering anti-deflection device, centering is carried out with anti-deviation to wirerope in the operational process of tower multi-rope friction hoisting machine.
Used technical solution is the utility model to solve above-mentioned technical problem: a kind of tower multi-rope friction type promotion
Machine is wrapped from centering anti-deflection device suitable for having set up n root wirerope, and the tower multi-rope friction hoisting machine of n > 2 on reel
First pulley group and second pulley group are included, the first pulley group includes n+1 pulley, and the n+1 pulley is along reel
It axially sets gradually, the axle center of the n+1 pulley is identical and parallel to each other at a distance from ground, makes the outer of two neighboring pulley
Race on circumference is opposite and is located at the axial two sides along reel of steel cable, passes through two neighboring pulley
Race cooperation on excircle limits axial displacement of the steel cable along reel, and the n+1 pulley is threaded through short pin
On axis, the two sides of the first pulley group are set there are two the first fixed frame, and all short pin shafts are installed in two the first fixed frames
Between；
The second pulley group is located at side of the first pulley group far from reel, and the second pulley group includes n to pulley,
The n is identical at a distance from ground to the axle center of pulley, two pulleys in each pair of pulley be located at steel cable along
The radial two sides of reel keep the race on the excircle of two pulleys of each pair of pulley opposite and are located at steel cable
The radial two sides along reel, by the race cooperation limitation steel cable on the excircle of two pulleys along reel
Radial displacement, the n are threaded through pulley respectively in two long pin shafts, and two long pin shafts are mounted on several the second fixed frames
On.
According to the above technical scheme, the beneficial effects of the utility model are:
A kind of tower multi-rope friction hoisting machine provided by the utility model passes through first pulley group from centering anti-deflection device
Axial displacement of each wirerope along reel is limited, radial position of each wirerope along reel is limited by second pulley group
It moves, sideslip occurs during lifting to avoid wirerope, it is simple and reasonable, it is easy to install and use and low in cost, and
And solving when tower multi-rope friction hoisting machine carries out centering to wirerope using guiding head sheave can be such that wirerope generates reversely
Bending, the problem of influencing the service life of wirerope, and make Structure of hoist complexity increased costs；Meanwhile because this programme makes
It is rotary pulley, rather than limits the displacement of wirerope using fixed mechanical structure, so when wirerope is sent out
Pulley can be rotated with the lifting of wirerope when raw sideslip, i.e., the present apparatus will not make wirerope and fixation while anti-deviation
Mechanical structure contact and friction and wear occurs, the lifting of neither influence wirerope will not reduce service life of wirerope.
