Abstract

The new underlying computer room drive chain swelling device of one kind of the present invention, belongs to field of elevator control.The head sprocket that it has motor and is connected to by drive chain on motor, drive chain side is provided with tensioner chainlet wheel assembly, tensioner chainlet wheel assembly is connected with guide spiro rod, block is fixed with guide spiro rod, the spring being arranged on guide spiro rod is provided between block and tensioner minor sprocket, guide spiro rod is connected with the supporting plate being fixed on computer room truss, and supporting plate is arranged on the both ends of guide spiro rod.Usefulness of the present invention is:Underlying computer room drive chain can not only be reached by the effect of tensioner, and compared with typically with nylon block compressible drive chain mode, the present apparatus uses the minor sprocket that the flank of tooth quenches, and not easy to wear, service life is longer;By spring-compressed minor sprocket tensioner drive chain, as long as adjusting spring Suitable compression amount when filling terraced, reach suitable pretightning force, drive chain can just be compressed automatically, without frequently manually adjusting in later stage maintenance.

Description

A kind of new underlying computer room drive chain swelling device
Technical field
The new underlying computer room drive chain swelling device of one kind of the present invention, belongs to field of elevator control.
Background technology
GB16899-2011《The manufacture of escalator and moving sidewalk and installation safety standard》It is middle to cancel underlying computer room This type of escalator.The underlying equal exportation abroad of computer room staircase of existing manufacturer's production.Because the type ladder amount is few, therefore seldom Drive chain needs tensioner when having producer's concern underlying computer room.All filled substantially without underlying computer room drive chain tensioner in usual products Put.A small number of producers extrude drive chain by nylon block and reach tensioner effect, but which make it that nylon block is easy to wear, Buddhist nun after abrasion Imperial block is not easy to change, and can not be automatically adjusted for drive chain tensioner amount, increases the difficulty of staircase maintenance.
The content of the invention
The technical problems to be solved by the invention are:There is provided one kind can automatic tension, avoid frequently adjusting during later stage maintenance Whole new underlying computer room drive chain swelling device.
For above technical problem, the new underlying computer room drive chain swelling device of one kind of the present invention, there is driving Motor and the head sprocket being connected to by drive chain on motor, drive chain side are provided with tensioner chainlet wheel assembly, tensioner Chainlet wheel assembly is connected with guide spiro rod, and block is fixed with guide spiro rod, is provided with and is arranged between block and tensioner minor sprocket Spring on guide spiro rod, guide spiro rod are connected with the supporting plate being fixed on computer room truss, and supporting plate is arranged on guiding spiral shell The both ends of bar.
Preferably, tensioner chainlet wheel assembly is arranged on the right side of drive chain, drive chain is entered using tensioner chainlet wheel assembly Row tensioner, the shortcomings that can avoiding using nylon block easy to wear, service life is improved, is needed during use as needed to rising The flank of tooth of minor sprocket in tight chainlet wheel assembly carries out Quenching Treatment, to improve the intensity of minor sprocket.
Preferably, block is arranged on the right side of tensioner chainlet wheel assembly, spring is arranged between tensioner minor sprocket and block, The nut for being used for adjusting stop location is provided with the right side of block, by adjusting nut compression spring, extrudes tensioner chainlet wheel assembly, it is right Drive chain plays a part of compressing tensioner.
Preferably, guide spiro rod both ends are bolted in supporting plate.
Compared with prior art, usefulness of the present invention is:Underlying computer room drive chain can not only be reached by the effect of tensioner Fruit, and compared with typically with nylon block compressible drive chain mode, the present apparatus uses the minor sprocket that the flank of tooth quenches, not easy to wear, makes It is longer with the life-span;By spring-compressed minor sprocket tensioner drive chain, as long as adjusting spring Suitable compression amount when filling terraced, reach suitable Pretightning force, drive chain can just be compressed automatically, without frequently manually adjusting in later stage maintenance.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is new underlying computer room drive chain swelling device use state diagram;
Fig. 2 is new underlying computer room drive chain swelling device structural representation.
In figure:1st, motor;2nd, drive chain;3rd, head sprocket;4th, tensioner chainlet wheel assembly;5th, guide spiro rod;6th, block; 7th, spring;8th, supporting plate;9th, nut.
Embodiment
The new underlying computer room drive chain swelling device of one kind of the present invention, there is motor 1 and pass through drive chain 2 The head sprocket 3 being connected on motor 1, the side of drive chain 2 are provided with tensioner chainlet wheel assembly 4, and tensioner chainlet wheel assembly 4 connects Guide spiro rod 5 is connected to, block 6 is fixed with guide spiro rod 5, is provided between block 6 and tensioner minor sprocket 4 and is arranged on guide spiro rod Spring 7 on 5, guide spiro rod 5 are connected with the supporting plate 8 being fixed on computer room truss, and supporting plate 8 is arranged on guide spiro rod 5 Both ends.
Preferably, tensioner chainlet wheel assembly 4 is arranged on the right side of drive chain 2, using tensioner chainlet wheel assembly 4 to drive chain 2 carry out tensioner, the shortcomings that can avoiding using nylon block easy to wear, service life are improved, as needed to rising during use The flank of tooth of minor sprocket in tight chainlet wheel assembly 4 carries out Quenching Treatment, to improve the intensity of minor sprocket.
Preferably, block 6 is arranged on the right side of tensioner chainlet wheel assembly 4, spring 7 is arranged on the He of tensioner chainlet wheel assembly 4 Between block 6, the right side of block 6 is provided with the nut 9 for being used for adjusting the position of block 6, and by the compression spring 7 of adjusting nut 9, extruding is risen Tight chainlet wheel assembly 4, drive chain 5 is played a part of to compress tensioner, the both ends of guide spiro rod 5 are bolted on supporting plate 8 On.
It is emphasized that:It the above is only the introduction and description of the occupation mode of the present invention, not the present invention made any Formal limitation, any simply modification, the equivalent variations that every technical spirit according to the present invention is made to above example With modification, in the range of still falling within technical solution of the present invention.
