As shown in fig. 1 and 2, the utility model provides a driving device for low-speed conveying of high-temperature materials, which comprises a horizontally arranged driving shaft 1, wherein driving sprockets 2 for driving a transmission chain to rotate are arranged at two ends of the driving shaft 1, heat preservation devices 3 are respectively arranged at the outer sides of the driving sprockets 2 at two ends, driving ratchet wheels 4 for driving the driving shaft 1 to rotate are arranged at the outer sides of the heat preservation devices 3, the driving device further comprises a driving oil cylinder 6, a pawl 5 is arranged on a piston rod of the driving oil cylinder 6, and the pawl 5 is meshed with external teeth of the driving ratchet wheels 4 and pushes down a piston rod of the driving oil cylinder 6 to drive the driving ratchet wheels 4 to rotate unidirectionally.
The technical scheme disclosed by the patent is applied to occasions where the driving chain wheel 2 drives the transmission chain to move at a low speed, and the requirements of continuous conveying are avoided, the transmission speed is generally crossed, and the scheme driving of the conventional common motor acceleration and deceleration machine cannot select such a large speed ratio. In the scheme, when the driving oil cylinder 6 works, thrust is applied to the meshed driving ratchet wheel 4 through the pawl 5 arranged at the end part of the piston rod, so that torque is generated, the driving ratchet wheel 4 rotates for a certain angle in a unidirectional rotation mode, then the piston rod is retracted and then extends out, the pawl 5 is continuously meshed with other external teeth of the driving ratchet wheel 4 and pushes the driving ratchet wheel 4 to rotate for a limited angle again, and accordingly the driving sprocket wheel 2 rotates at a low speed to drive materials to advance.
In this structure, because the driving components such as the driving ratchet wheel 4 and the driving oil cylinder 6 are all arranged outside the heat preservation device 3, and the components such as the driving oil cylinder 6 which are sensitive to temperature do not form a whole with the main body transmission components such as the driving shaft 1 in the main body, the heat of the high-temperature material only has an influence on the parts such as the driving sprocket 2 and the driving shaft 1 between the heat preservation devices 3, the driving oil cylinder 6 and the like cannot have a heat influence, and the service life of the hydraulic part is ensured.
Meanwhile, the average rotating speed of the driving ratchet wheel 4 can be controlled by adjusting the working frequency and the running speed of the driving oil cylinder 6, and as the driving chain wheel 2 and the driving ratchet wheel 4 are both arranged on the driving shaft 1 and have the same rotating speed, the driving chain wheel 2 can rotate at the same average rotating speed at a low speed under the driving of the driving ratchet wheel 4, so that the low-speed conveying of high-temperature materials is realized.

The traction effect of the return spring 7 can ensure that the pawl 5 is always attached to the external teeth of the driving ratchet wheel 4, and when the piston rod is retracted after the pushing of one working process is finished, the pawl 5 can be quickly meshed with the external teeth of the driving ratchet wheel 4 under the traction of the return spring 7, so that the next working process is ready.
The two driving ratchet wheels 4 are respectively arranged on the outer sides of the heat preservation devices 3 at the two ends, and the two driving ratchet wheels 4 are respectively driven to rotate in a unidirectional way by the corresponding driving oil cylinders 6. By arranging the driving ratchet wheel 4 and the driving oil cylinders 6 on both sides, on one hand, the stress on both sides is uniform, the stress structure of the driving shaft 1 is balanced, the faults of chain clamping, chain releasing and the like are avoided, meanwhile, the driving oil cylinders 6 on both sides can be adjusted to be consistent or opposite in working beats in actual working, when the working beats are consistent, the driving moment on the driving shaft 1 can be obviously increased, and the carrying capacity is increased; when the working beats are opposite, the driving ratchet wheels 4 at the two sides are alternately and continuously applied with the rotating moment, so that the rotating speed of the driving ratchet wheels 4 can be increased, and the acceleration conveying is realized.
