Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments.

Referring to fig. 1 and 2, the return track 40 system of the invention comprises a kettle front track 10, a kettle inner track 20, a kettle rear track 30 and a return track 40, wherein the kettle rear track 30 and the return track 40, the return track 40 and the kettle front track 10 are connected through a ferry track 50, the ferry track 50 is provided with a ferry vehicle 60 in a sliding manner, a steam curing trolley fully loaded with cut-formed brick blanks runs along the kettle front track 10 to enter the kettle inner track 20 of the autoclave for steam curing, the steam curing trolley after steam curing is pulled out of the autoclave to enter the kettle rear track 30, and is ferred to the return track 40 through the ferry track 50 and then is ferred to the kettle front track 10 through the ferry track 50, thereby completing a circulation flow. The ferry track 50 of the present invention includes an upper running track 51, a lower running track 52, and a lifting device 53, wherein the lifting device 53 is disposed at both ends of the upper running track 51 and the lower running track 52, and the upper running track 51, the lower running track 52, and the lifting device 53 constitute a circulating track of the ferry vehicle 60.

After autoclaved curing is completed, the aerated bricks are driven out of an autoclave along with a steam curing trolley and enter a post-kettle track 30, a ferry vehicle 60 runs along an upper running track 51 to be in butt joint with the post-kettle track 30 corresponding to the steam curing trolley to be ferried, the steam curing trolley drives up the ferry vehicle 60, runs along the ferry vehicle 60 to be in butt joint with a return track 40, the steam curing trolley drives into the return track 40, then the ferry vehicle 60 continuously runs to a lifting device 53, descends to the height of a lower running track 52 along the lifting device 53, then the ferry vehicle 60 drives into the lower running track 52, runs to the lifting device 53 at the other end along the lower running track 52, and ascends to the height of the upper running track 51 under the action of the lifting device 53, and then circulation of the ferry vehicle 60 is realized. At least two ferry vehicles 60 can be arranged on the whole circulating track, so that when one or more of the ferry vehicles 60 are in the circulating process, the other one or more of the ferry vehicles 60 are in the state of transporting the steam-cured trolleys, and the return speed of the steam-cured trolleys in the whole steam-oxygen flow is increased. The same is true for the working principle of the ferry track 50 connecting the return track 40 and the pre-tank track 10.

Referring to fig. 2 again, the lifting device 53 of the present invention includes a lifting platform 531, a telescopic cylinder 532 and a support base 533, wherein an output end of the telescopic cylinder 532 is connected to the lifting platform 531, and the other end of the telescopic cylinder 532 is fixed on the support base 533, and the lifting platform 531 is driven by the telescopic cylinder 532 to move to be flush with the upper running rail 51 or the lower running rail 52. The lifting platform 531 is provided with a parking track 5311 along the extending direction of the upper running track 51, the parking track 5311 runs along with the lifting platform 531 to be butted with the upper running track 51 or the lower running track 52 under the driving of the telescopic cylinder 532, so that the ferry vehicle 60 conveniently and quickly runs on the lifting platform 531. In order to prevent the ferry vehicle 60 from running out of the parking track 5311 and separating from the whole ferry track 50, a fixed limiting piece 5312 is arranged at one end of the parking track 5311 far away from the upper running track 51, and a limiting groove matched with the roller of the ferry vehicle 60 is formed in one surface, facing the ferry vehicle 60, of the fixed limiting piece 5312. The ferry vehicle 60 drives into the parking track 5311 and is finally embedded in the limiting groove. The fixed limiting part 5312 has a fixing effect on the ferry vehicle 60 to a certain extent, and can ensure the stability of the ferry vehicle 60 in the lifting process. The limiting groove is provided with a pressure sensor which receives pressure from the roller of the ferry vehicle 60. When the ferry vehicle 60 slides to the parking track 5311, the pressure sensor receives the pressure from the roller of the ferry vehicle 60 and transmits a pressure signal to the PLC controller, the PLC controller controls the telescopic cylinder 532 of the lifting device 53 to contract, and the lifting platform 531 descends until the parking track 5311 is in butt joint with the lower running track 52.

In order to better fix the ferry vehicle 60 on the lifting platform 531 and prevent the ferry vehicle 60 from moving relative to the parking track 5311 during the lifting process, a movable track 5313 is hinged to one end of the parking track 5311 close to the upper running track 51, and the movable track 5313 is movably supported on the lifting platform 531 through a telescopic rod 5314. The output shaft of the telescopic rod 5314 is hinged with the movable rail 5313, and the other end is fixed on the lifting platform 531. Specifically, the platform surface of the lifting platform 531 is provided with a mounting groove 5315 downwards, and the telescopic rod 5314 is mounted in the mounting groove 5315. When the telescopic rod 5314 is in a retracted state, the upper end surface of the movable rail 5313 is flush with the upper end surface of the parking rail 5311, and when the telescopic rod 5314 extends, the movable rail 5313 is driven to rotate by a certain angle relative to the parking rail 5311. When the ferry vehicle 60 is parked on the lifting platform 531, one set of rollers of the ferry vehicle 60 is embedded in the fixed position-limiting piece 5312, the other set of rollers is located at the hinge joint of the movable rail 5313 and the parking rail 5311, and after the movable rail 5313 rotates for a certain angle relative to the parking rail 5311, the end surface of the movable rail 5313 is abutted against the rollers, so that the ferry vehicle 60 is confined between the movable rail 5313 and the fixed position-limiting piece 5312.

Because the movable rail 5313 is hinged to the parking rail 5311, in order to ensure smooth rotation of the movable rail 5313 and good butt joint of the movable rail 5313 with the upper cloud planet rail or the lower running rail 52, first inclined surfaces are arranged at two ends of the upper running rail 51 and the lower running rail 52, and a second inclined surface which is matched with the first inclined surfaces is arranged at the movable end of the movable rail 5313.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments.
