Description
Technical field：
The present invention relates to escalator or moving sidewalk field, more particularly to a kind of handrail strap tensioning device.
Background technology：
Handrail is the important component of escalator, and existing handrail strap tensioning device uses spring structure substantially,
Such as a kind of handrail strap tensioning device of external wheel of patent CN101590969A, the general one day escalator operation time only has several small
When, but either whether staircase is in running order, handrail remains that handrail is in tensioner state, is helped after long-time
Phenomena such as hand strap occurs cracking, elongation, and the structure swelling device needs the periodic de-regulation spring pressure of maintenance staff
Contracting amount, is easy for producing phenomena such as handrail belt sag skids if do not adjusted, and thinks that adjusting need to largely dismount work.
The content of the invention：
The purpose of the present invention and provides a kind of handrail strap tensioning device, using flexible aiming at the deficiency of the prior art
Hydraulic cylinder provides expanding force, controls telescopic hydraulic cylinder pressure with valve group, valve group is electrically connected switch board, when escalator operation time control
Hydraulic pressure in-cylinder pressure is constant is kept constant in some rational fixed value, i.e. expanding force for the control of cabinet processed instruction valve group, makes handrail
Fully reasonable effective tensioner, and when escalator, job control hydraulic cylinder does not reduce pressure, alleviates handrail strap tensioning state, subtracts
Few handrail fatigue usage time, so that the service life of handrail is greatly improved, and it is automatically controlled using switch board, it can fill
Code insurance demonstrate,proves the stability of handrail strap tensioning, improves safe handling property, the work of periodic adjustment spring is avoided, when saving maintenance
Between.
The technology solution of the present invention is as follows：
A kind of handrail strap tensioning device, including handrail, roller station, press nips, further include installing plate, are fixed on the peace
Telescopic hydraulic cylinder in loading board, the telescopic hydraulic cylinder external part are fixedly connected with press roll component, and the telescopic hydraulic cylinder connects
Valve group is connect, valve group ensures that telescopic hydraulic cylinder hydraulic pressure in-cylinder pressure when staircase is run is constant, and the valve group is electrically connected switch board.
Preferably, the installing plate is equipped with two sliding slots, the press roll component is equipped with welded nut, and bolt passes through
Sliding slot is connected with welded nut, and the bolt leaves gap with installing plate.
Preferably, the installing plate is fixed on truss.
Preferably, the roller of the press roll component is at least 3
The beneficial effects of the present invention are：Expanding force is provided using telescopic hydraulic cylinder, telescopic hydraulic cylinder pressure is controlled with valve group
Power, valve group are electrically connected switch board, and when escalator operation, switch board instruction valve group control hydraulic pressure in-cylinder pressure is constant at some
Rational fixed value, i.e. expanding force are kept constant, and make handrail fully reasonable effective tensioner, and when escalator does not work control
Hydraulic cylinder processed reduces pressure, alleviates handrail strap tensioning state, reduces handrail fatigue usage time, is helped so as to greatly improve
The service life of hand strap, and it is automatically controlled using switch board, it can fully ensure that the stability of handrail strap tensioning, improve safe handling
Property, the work of periodic adjustment spring is avoided, saves the maintenance time.
Brief description of the drawings：
The following drawings is only intended to, in doing schematic illustration and explanation to the present invention, not delimit the scope of the invention.Wherein：
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is A-A cuttings partial schematic diagram of the present invention,
Fig. 3 is enlarged diagram at B of the present invention；
Fig. 4 is control system schematic diagram of the present invention
Embodiment：
As shown in Fig. 1 to Fig. 4, a kind of handrail strap tensioning device, including handrail 1, roller station 2, press nips 3, further include
Installing plate 6, the telescopic hydraulic cylinder 4 being fixed on the installing plate 6,4 external part of telescopic hydraulic cylinder are fixed with press roll component 3
Connection, the telescopic hydraulic cylinder 4 connect valve group 9, and valve group 9 ensures the hydraulic cylinder internal pressure when staircase is run of telescopic hydraulic cylinder 4
Power is constant, and the valve group 9 is electrically connected switch board 10.
Preferably, the installing plate 6 is equipped with two sliding slots 5, the press roll component 3 is equipped with welded nut 11, spiral shell
Bolt 7 is connected through sliding slot 5 with welded nut 11, and the bolt 7 leaves gap 12 with installing plate 6.
Preferably, the installing plate 6 is fixed on 8 on truss.
Preferably, the roller 13 of the press roll component 3 is at least 3
Operation principle：Pinch roller assembly is driven using telescopic hydraulic cylinder, pinch roller assembly upper pressure wheel is pressed on the inside of handrail, from
And making handrail strap tensioning, telescopic hydraulic cylinder pressure is constant, and the expanding force that handrail is subject to is constant, and telescopic hydraulic is controlled with valve group
Cylinder pressure, valve group be electrically connected switch board, when escalator operation, switch board instruction valve group control hydraulic pressure in-cylinder pressure it is constant
Some rational fixed value, i.e. expanding force are kept constant, and make the fully reasonable effective tensioner of handrail, and work as escalator not work
Making control hydraulic cylinder reduces pressure, alleviates handrail strap tensioning state, handrail fatigue usage time is reduced, so as to greatly improve
The service life of handrail, and it is automatically controlled using switch board, it can fully ensure that the stability of handrail strap tensioning, improving safety makes
With property, the work of periodic adjustment spring is avoided, saves the maintenance time.
The energy embodiment is to be illustrated the present invention, not for the limitation present invention.Any people in the art
Member can modify the embodiment under the spirit and scope without prejudice to the present invention, therefore the rights protection of the present invention
Scope, should be as listed by the claim of the present invention.
