Description
Technical field
The utility model is related to novel underlying computer room drive chain swelling device, belong 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.Since the type ladder amount is few, therefore seldom
Drive chain needs tensioner when having producer to pay close attention to underlying computer room.It is all filled substantially without underlying computer room drive chain tensioner in usual products
It sets.A small number of producers squeeze drive chain by nylon block and reach tensioner effect, but which so that nylon block is easy to wear, Buddhist nun after abrasion
Imperial block is not easy to replace, and drive chain tensioner amount can not be automatically adjusted, and increases the difficulty of staircase maintenance.
Invention content
Technical problem to be solved in the utility model is：There is provided one kind can automatic tension, avoid later stage maintenance time-frequency
The novel underlying computer room drive chain swelling device of numerous adjustment.
For the above technical problem, the utility model is related to novel underlying computer room drive chain swelling device, there is driving
Motor and the head sprocket on driving motor is connected to by drive chain, drive chain side is provided with tensioner chainlet wheel assembly, tensioner
Chainlet wheel assembly is connected with guide spiro rod, and block is fixed on guide spiro rod, is equipped with and is mounted between block and tensioner minor sprocket
Spring on guide spiro rod, guide spiro rod are connected with the support plate being fixed on computer room truss, and support plate is arranged in guide spiro rod
Both ends.
Preferably, tensioner chainlet wheel assembly be arranged on the right side of drive chain, using tensioner chainlet wheel assembly to drive chain into
Row tensioner can improve service life, needed as needed during use to rising to avoid using nylon block disadvantage easy to wear
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 in tensioner chainlet wheel assembly and block
Between, it is equipped with the nut for adjusting stop location on the right side of block, by adjusting nut compressed spring, squeezes tensioner minor sprocket group
Part plays the role of drive chain to compress tensioner.
Preferably, guide spiro rod both ends are bolted in support plate.
Compared with prior art, the usefulness of the utility model is：Underlying computer room drive chain can not only be reached by tensioner
Effect, and with generally with nylon block compressible drive chain mode compared with, the present apparatus use the flank of tooth quench minor sprocket, be not easy to grind
Damage, the service life is longer；It is reached by spring-compressed minor sprocket tensioner drive chain as long as adjusting spring Suitable compression amount when dress ladder
To suitable pretightning force, drive chain can be compressed automatically, without frequently manually adjusting in later stage maintenance.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is novel underlying computer room drive chain swelling device use state diagram；
Fig. 2 is novel underlying computer room drive chain swelling device structural schematic diagram.
In figure：1, driving motor；2, drive chain；3, head sprocket；4, tensioner chainlet wheel assembly；5, guide spiro rod；6, block；

Both ends.
Preferably, tensioner chainlet wheel assembly 4 is arranged on 2 right side of drive chain, using tensioner chainlet wheel assembly 4 to drive chain
2 carry out tensioner, service life can be improved, as needed to rising during use to avoid using nylon block disadvantage easy to wear
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, the setting of block 6, on 4 right side of tensioner chainlet wheel assembly, spring 7 is arranged in 4 He of tensioner chainlet wheel assembly
Between block 6,6 right side of block is equipped with the nut 9 for adjusting 6 position of block, and by 9 compressed spring 7 of adjusting nut, extruding is risen
Tight chainlet wheel assembly 4 plays the role of drive chain 5 to compress tensioner, and 5 both ends of guide spiro rod are bolted on support plate 8
On.
It is emphasized that：It the above is only the introduction and description of the occupation mode of the utility model, it is not new to this practicality
Type makes any form of restriction, made by the above technical examples according to the technical essence of the present invention any simply to repair
Change, equivalent variations and modification, is still within the scope of the technical solutions of the present invention.
