Independent tensioning is extremely important.
Utility model content
The utility model provides a kind of chain dual drive wheel lazy-tongs that can be independently tensioned, and solving the prior art cannot
The problem of independent tensioning.A kind of chain dual drive wheel lazy-tongs that can be independently tensioned, including the first rack for being arranged symmetrically
With the second rack, the first driving gear driven by the first motor is installed, with first sliding tooth in first rack
Take turns the first reduction gearing of engagement, the first synchromesh gear engaged with first reduction gearing, with first reduction gearing
Coaxial mounted first sprocket wheel is correspondingly separately installed with the second sliding tooth driven by the second motor in second rack
Wheel, the second reduction gearing engaged with the second driving gear, the second synchromesh gear engaged with second reduction gearing,
With coaxial mounted second sprocket wheel of second reduction gearing.
Further, the first reduction gearing number of teeth is more than the first driving number of gear teeth and described first slows down
Number of gear teeth is more than the first synchromesh gear number of teeth；Correspondingly, the second reduction gearing number of teeth is more than the second driving gear
The number of teeth and the second reduction gearing number of teeth are more than the second synchromesh gear number of teeth.
Further, it is connected by shaft coupling between first synchromesh gear and second synchromesh gear.
Preferably, the shaft coupling is Rzeppa constant velocity joint.
Further, it is provided with first hydraulic cylinder in first rack, the second hydraulic pressure is provided in second rack
Cylinder is respectively used to the independent tensioning for the chain installed on the first sprocket wheel and the second sprocket wheel.
Optionally, first sprocket wheel and the second sprocket wheel and chain parallel arrangement.
Optionally, first sprocket wheel and the angled arrangement of the second sprocket wheel and chain.
Compared with prior art, the utility model respectively drives two chains by two motors, and realizes that two chains are same
Step transmission, solves the problems, such as that the prior art cannot be independently tensioned.

Specific implementation mode
With reference to figure 1 and Fig. 2, a kind of chain dual drive wheel lazy-tongs that can be independently tensioned, including be arranged symmetrically
One rack 4 and the second rack 4 ' are equipped with the first driving gear 2 driven by the first motor 1 in first rack, and described
First reduction gearing 3 of the first driving gear engagement, the first synchromesh gear 5 engaged with first reduction gearing are and described
Coaxial mounted first sprocket wheel 6 of first reduction gearing is correspondingly separately installed in second rack and is driven by the second motor 1 '
The second dynamic driving gear 2 ', the second reduction gearing 3 ' engaged with the second driving gear, with second reduction gearing
Second synchromesh gear 5 ' of engagement, with coaxial mounted second sprocket wheel 6 ' of second reduction gearing.
The first reduction gearing number of teeth is more than the first driving number of gear teeth and the first reduction gearing number of teeth is big
In the first synchromesh gear number of teeth, so that it is guaranteed that the high rotating speed of the first motor input is converted into the slow-speed of revolution of sprocket wheel output；Correspondingly,
The second reduction gearing number of teeth is more than described second and number of gear teeth and the second reduction gearing number of teeth is driven to be more than second together
Walk number of gear teeth.
With reference to figure 4 and Fig. 5, it is provided with first hydraulic cylinder 9 in first rack, second is provided in second rack
Hydraulic cylinder 9 ' is respectively used to the independent tensioning for the chain installed on the first sprocket wheel 6 and the second sprocket wheel 6 '.Because using process
In, the shake allowance of two chains is inconsistent, and carrying out tensioning to different chains respectively is more advantageous to operation and maintenance.
With reference to figure 6, connected by shaft coupling 7 between first synchromesh gear and second synchromesh gear.Particularly, institute
It is Rzeppa constant velocity joint to state shaft coupling.After Rzeppa constant velocity joint may be implemented in independent tensioning, first is same
When walking gear and not coaxial the second synchromesh gear, constant speed synchronizing function still may be implemented.
With continued reference to Fig. 6, first sprocket wheel, 6 and second sprocket wheel 6 ' and chain can be arranged in parallel.When required cutting pours
When concrete diaphragm wall is non-parallel, first sprocket wheel, 6 and second sprocket wheel 6 ' and chain can also be at an angle of arrangement.
In a kind of embodiment, if required cutting force is little, the shaft coupling 7 between the first sprocket wheel 6 and the second sprocket wheel 6 ' is taken off
It opens, the first motor 1 or the second motor 1 ' can be only there are one moving, to save the energy.
Example discussed above is only the chain dual drive wheel lazy-tongs that can be independently tensioned to the utility model
Embodiment is described, and is not defined to the scope of the utility model, is not departing from the spirit of the design of the utility model
Under the premise of, the various modifications and improvement that those of ordinary skill in the art make the technical solution of the utility model should all be fallen into
In the protection domain that the utility model claims book determines.
