Abstract

A multi-group linkage friction wheel driving mechanism comprises a base and more than one friction wheel unit. Each friction wheel unit is composed of a swinging arm, chain wheels and a chain friction wheel, and the upper end of the swinging arm is connected with a friction wheel through a friction wheel shaft. The friction wheel driving mechanism further includes a long shaft, two ends of the long shaft are fixed on a bearing seat of the base through a rolling bearing sleeve piece, and one end of the long shaft is connected with a rotating driving device. A shaft hole at the lower end of the swinging arm is in rotatable connection with the long shaft, the friction wheel shaft and the long shaft are respectively connected with the chain wheels, and the corresponding chain wheels are connected with each other through chains.

Description

A kind of friction wheel driving mechanism of many group interlocks

Technical field

The utility model relates to a kind of fraction wheel drive device, is particularly useful for the drawing cable of multi-joint cable reel.

Background technology

At present, domestic friction wheel driving mechanism is simply connected mechanism, and as shown in Figure 1, friction wheel driving mechanism is made up of base plate, arm shaft, swing arm axle bed, friction wheel, friction wheel axle, sprocket wheel, chain, spring, swing arm and spring perch; Described swing arm axle bed and spring perch are separately fixed on the base plate, and described swing arm is fixed on the swing arm axle bed by arm shaft; Described both ends of the spring is separately fixed in spring perch and the swing arm, the swing arm other end links to each other with friction wheel by friction wheel axle, corresponding sprocket wheel is housed respectively on friction wheel axle and arm shaft, is connected by a closed loop chain on two sprocket wheels, arm shaft rotating band dynamic friction wheel rotates synchronously.This friction wheel driving mechanism only can carry out drawing cable to single cable reel; and carrying out multi-joint cable reel when carrying out folding and unfolding; existing mechanism then can't realize; usually can adopt manual folding and unfolding mode to carry out; so not only influence the operation process, and increased the labour intensity of operating worker.

Summary of the invention

In order to solve the drawing cable problem of existing multi-joint cable reel, the utility model provides a kind of friction wheel driving mechanism of many group interlocks, and this device can not only be to every group of cable reel simultaneously or folding and unfolding separately, and simple to operate, safe and reliable.

The technical scheme that realizes the utility model purpose is:

A kind of friction wheel driving mechanism of many group interlocks comprises base and more than one friction wheel unit, and each friction wheel unit is made up of swing arm, sprocket wheel, chain friction wheel, and the swing arm upper end links to each other with friction wheel by friction wheel axle; Described friction wheel driving mechanism also comprises major axis, and the major axis two ends are fixed on by the antifriction-bearing box external member on the bearing seat of base, and major axis one end is connected with rotating driving device; The axis hole of described swing arm lower end is connected with major axis is rotatable, is connected with described sprocket wheel on friction wheel axle and major axis respectively, and described chain couples together cooresponding sprocket wheel.

In the utility model, the major axis two ends are fixed on the base by the antifriction-bearing box external member, some swing arms are housed on major axis, swing arm can freely be rotated around major axis, friction wheel and sprocket wheel are housed in each swing arm, couple together by chain and the sprocket wheel that is fixed on the major axis, major axis is rotated under the driving of actuating device, drive all sprocket wheels and friction wheel from rotation, realize the synchronous folding and unfolding of multi-joint cable reel.Each swing arm can rotate freely around major axis, can select to carry out the cable reel of folding and unfolding.

Described antifriction-bearing box external member comprises antifriction-bearing box, circlip for shaft and circlip for bore.

The axis hole and the major axis of described swing arm lower end are connected on the described major axis by antifriction-bearing box and spacer.

Described actuating device can be HM Hydraulic Motor or electrical motor.

As further improvement of the utility model, on major axis, the axial location circle is loaded onto at each swing arm two ends respectively, and the swing arm position can be carried out longitudinal travel as required and be moved the location, back.

The beneficial effects of the utility model are, have solved the drawing cable problem of multi-joint cable reel, and can regulate each friction wheel position change in displacement on major axis as required, have reduced operation labor intensity, and are simple in structure.
