Description
Technical field：
The present invention relates to escalator or moving sidewalk field, more particularly to a kind of hydraulic cylinder type handrail strap tensioning to fill
Put.
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
Hand strap occurs cracking, and phenomena such as elongation, and the structure swelling device needs the periodic de-regulation spring pressure of maintenance staff
Contracting amount, it is easy for producing phenomena such as handrail belt sag skids if do not adjusted, and thinks that regulation 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 prior art
Hydraulic cylinder provides expanding force, and telescopic hydraulic cylinder pressure, valve group electrical connection switch board, when escalator operation time control are controlled with valve group
Cabinet instruction valve group control hydraulic pressure in-cylinder pressure processed is constant to be kept constant in some rational fixed value, i.e. expanding force, 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 as to greatly improve the service life of handrail, 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 hydraulic cylinder type handrail strap tensioning device, including handrail, bottom roller group part, handrail driving wheel, truss,
Also include installing plate, telescopic hydraulic cylinder, bottom roller group part is movably fixed on the installing plate, the telescopic hydraulic cylinder
Base is fixed with truss, and the telescopic hydraulic cylinder telescoping cylinder is fixedly connected with bottom roller group part, 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 electrically connects switch board.
Preferably, the installing plate is provided with chute, bottom roller group part is fixed by bolts and nuts activity
On the installing plate.
Preferably, the bolt root uses flat tenon structure, the flat tenon structure is stuck in chute.
Preferably, the roller of bottom roller group part is at least 3.
The beneficial effects of the present invention are：The handrail strap tensioning fatigue time is reduced, improves service life, working condition is steady
It is fixed, safety in utilization is not only improved, also 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 structural representation of the present invention；
Fig. 2 is control system sketch of the present invention,
Fig. 3 is bolt side view；
Fig. 4 is bolt top view
Embodiment：
As shown in Fig. 1 to Fig. 4, a kind of hydraulic cylinder type handrail strap tensioning device, including handrail 1, bottom roller group part 5,
Handrail driving wheel 3, truss 2, in addition to installing plate 6, telescopic hydraulic cylinder 4, bottom roller group part 5 are movably fixed to described
On installing plate 6, the base of telescopic hydraulic cylinder 4 is fixed with truss 2, the telescoping cylinder of telescopic hydraulic cylinder 4 and bottom roller group part 5
It is fixedly connected, the telescopic hydraulic cylinder 4 connects valve group 9, and valve group 9 ensures the hydraulic cylinder when staircase is run of telescopic hydraulic cylinder 4
Interior pressure is constant, and the valve group 9 electrically connects switch board 10.
Preferably, the installing plate 6 is provided with chute 7, bottom roller group part 5 is lived by bolt 8 and nut 11
It is dynamic to be fixed on the installing plate 6.
Preferably, the root of bolt 8 uses flat tenon structure 12, the flat tenon structure 12 is stuck in chute 7.
Preferably, the roller 13 of bottom roller group part 5 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 electrical connection 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 keep constant, 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, the stability of handrail strap tensioning is can fully ensure that, improving safety makes
With property, the work of periodic adjustment spring is avoided, saves the maintenance time.
The energy embodiment is to the illustrative present invention, not for the limitation present invention.Any people in the art
Member can modify under the spirit and scope without prejudice to the present invention to the embodiment, therefore the rights protection of the present invention
Scope, should be as listed by the claim of the present invention.
