Description
Technical field
The present invention relates to methane tank body and manufacture field, particularly a kind of many trains lifting drive system.
Background technique
The assembled tank of biogas, as a kind of new methane tank body form, is applied increasingly extensive in biogas industry.As shown in Figure 1, in the installation process of assembled tank, the assembled plate 2 of whole circle with layer on assembled tank 1 upwards need to be promoted to identical specified altitude along lift simultaneously, then on lift, carry out the installation of next layer of assembled plate 2, and then pass through elevator lifting, thereby carry out from level to level the installation of assembled plate 2, so circulation is until install.This mounting type needs special auxiliary drive apparatus to carry out synchronous lifting to assembled plate.
As shown in Figure 2, existing driving arrangement mainly comprises 3 one of speed reducers and a sprocket wheel (not shown).This driving arrangement directly drives sprocket rotation by middle speed reducer, and sprocket wheel drives lift 4 by a chain 5.Bottom, the assembled joint of assembled tank is respectively equipped with lift 4, and lift is for promoting tank body assembled plate around.Driving arrangement is delivered to lifting force on all lifts 4 by this chain 5, then drives the assembled plate 2 of whole circle by lift 4, with this, makes the assembled plate 2 of a circle increase.This equipment facts have proved, small-sized tank body can carry out the installation of assembled tank 1 smoothly by this lifting gear.
But the assembled tank of biogas is larger, the defective mounting that this drive system exists is also just more obvious.In this drive system, only contain a chain, the larger corresponding chain of tank body specification is also just longer.Because chain exists error in tensioning process, and every sections of chain all can have error, and the longer cumulative error of chain is also just larger.Because the accumulated deformation of chain makes the closer to chain end amount of deformation larger; thereby the lift 4 that is arranged on tank body assembled joint around can not synchronous working; thereby just need to be within an operation cycle (lifting of a laminate); shut down for several times; manually the feed screw nut of described lift is adjusted, every lift is on equal height.So not only strengthen workload, and manually the flexible of chain controlled, tended to personnel to cause accidental injury.
In order to overcome the above problems, the present invention has done useful improvement.
Summary of the invention
(1) technical problem that will solve
The object of this invention is to provide a kind of pleiotaxy lifting drive system, overcome existing driving arrangement and can not guarantee the technical problem of tank body Synchronous lifting because of chain cumulative error.
(2) technological scheme
The present invention is achieved by the following technical solutions: a kind of many trains lifting drive system, comprises speed reducer, gear drive and a plurality of sprocket wheel; Described speed reducer drives described a plurality of sprocket wheels by described gear drive; Described each sprocket wheel is connected by a chain with one or more elevator mechanisms accordingly.
Wherein, described gear drive comprises main drive gear and a plurality of driven gear, and described a plurality of driven gears and described a plurality of sprocket wheel connect one to one; Described speed reducer drives described main drive gear to rotate, and described main drive gear drives driven gear to rotate again, thereby drives described a plurality of sprocket wheel.
Further, described a plurality of driven gear arranges respectively around described main drive gear; Described sprocket wheel is arranged on described driven gear downside, and described sprocket wheel and described driven gear coaxial transmission.
Further again, described a plurality of driven gears are evenly distributed on described main drive gear around.
Preferably, described gear drive comprises five driven gears.
Wherein, described many trains lifting drive system also comprises a plurality of automatic chain tensioning devices, and described automatic chain tensioning device is arranged on described chain.
(3) beneficial effect
Compare with product with prior art, the present invention has the following advantages:
The present invention adopts gear drive to drive a plurality of chain drive elevator mechanisms, adopt a plurality of chains, therefore reduced the length of chain, the cumulative error of chain is reduced greatly, error is controlled in allowed band, guarantee the big-and-middle-sized methane tank body Synchronous lifting of assembled plate around, saved cost of labor, guaranteed manufacturing efficiency.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
As shown in Figure 3 and Figure 4, the present embodiment provides a kind of many trains lifting drive system, comprises driving arrangement 6 and a plurality of sprocket wheel 10; Described driving arrangement 6 comprises speed reducer 3 and gear drive; Described speed reducer 3 drives described a plurality of sprocket wheels 10 by described gear drive; Elevator mechanism adopts lift 4 to promote assembled plate.Speed reducer 3 operated by rotary motion are in assembled tank neutral position; Described each sprocket wheel 10 is connected by a chain 5 with one or several lift 3 accordingly.The present invention coordinates with sprocket wheel by gear drive, by elevator mechanism of single chain drive, thereby, at tank for sewage gas tank body around in assembled plate installation process, by elevator lifting with the assembled plate of layer to setting height.Owing to adopting a plurality of sprocket wheels and corresponding many chains that connect, single chain length is shorter, also just reduced the cumulative error of every chain, make error in allowed band, thereby guaranteed the Synchronous lifting of the assembled plate in tank for sewage gas tank body border, without the artificial elevator mechanism of adjusting, improved manufacturing efficiency.
Particularly, as shown in Figure 4 and Figure 5, described gear drive can comprise main drive gear 8 and a plurality of driven gear 9, and described a plurality of driven gears 9 connect one to one with described a plurality of sprocket wheels 10; Described speed reducer 3 drives described main drive gear 8 to rotate, and described main drive gear 8 drives driven gear 9 to rotate again, thereby drives described a plurality of sprocket wheel 10.The structure that adopts a plurality of driven gears and described a plurality of sprocket wheel to connect one to one, guarantees that the driving torque of each sprocket wheel is identical, is the stressed even of every chain, guarantees stably Synchronous lifting of assembled plate.
