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.

As shown in fig. 1 and 2, the still kettle rail docking device of the present invention includes a kettle front rail 10, a kettle inner rail 20, and a connecting rail 30 movably disposed between the kettle front rail 10 and the kettle inner rail 20, wherein the connecting rail 30 includes a fixed rail 31 and a movable rail 32, the movable rail 32 is rotatably connected to the fixed rail 31, one end of the movable rail 32 far from the fixed rail 31 is provided with a concave portion 321, an end portion of the kettle inner rail 20 is provided with a convex portion matched with the concave portion 321, the movable rail 32 is rotated to be flush with the kettle inner rail 20, the convex portion is inserted into the concave portion 321, and a reserved distance exists between an end surface of the convex portion and a bottom surface of the concave portion 321. The reserved distance is the distance between the kettle inner rail 20 and the movable rail 32 when the movable rail 32 can just rotate to the position flush with the kettle inner rail 20 relative to the fixed rail 31 under the condition that the fixed rail 31 is flush with the kettle front rail 10 in the butt joint. In the presence of the predetermined distance, the movable rail 32 can rotate smoothly to be flush with the rail 20 in the tank.

When the device is used, the connecting track 30 is arranged between the kettle front track 10 and the kettle inner track 20, the fixed track 31 is flush with the kettle front track 10, the movable track 32 is opened by rotating to drive the movable track to rotate relative to the fixed track 31 to be flush with the kettle inner track 20, and the convex part is inserted into the concave part 321, so that the butt joint work of the kettle front track 10 and the kettle inner track 20 is completed, and the subsequent steam-curing trolley enters the still kettle to work; after the steam-curing trolley enters the still kettle for a plurality of times, the movable rail 32 is rotated and folded to be attached to the fixed rail 31, so that the connecting rail is moved to a kettle door closing position where the connecting rail does not interfere with the still kettle. The movable rail 32 rotates and extends into the still kettle to realize butt joint with the inner rail 20 of the still kettle, and the interval between the connecting rail 30 and the inner rail 20 of the still kettle can be effectively reduced, so that the collision between the steam-curing trolley and the inner rail 20 of the still kettle is reduced, and the driving stability of the steam-curing trolley is improved. In addition, after the movable rail 32 is in butt joint with the rail 20 in the kettle, due to the arrangement of the convex part and the concave part 321, the interval between the rails spliced by the movable rail 32 and the rail 20 in the kettle is presented on the top surface of the rails in a staggered manner, so that the movable rail 32 and the rail 20 in the kettle are always continuous without the interval crossing the whole top surface of the rails, continuous support can be provided for the steam-curing trolley, the contact area between the wheels of the steam-curing trolley and the rails when the wheels of the steam-curing trolley pass through the interval gaps is effectively increased, and the running stability of the wheels of the steam-curing trolley is not; and, movable rail 32 rotates to be connected on fixed rail 31, and it can rotate to laminating with fixed rail 31 for the length of whole connecting rail 30 is less than the distance of track 10 to the still kettle body tip before the cauldron, thereby can not hinder connecting rail 30's removal, provides sufficient space for opening and closing of still kettle door.

The operating environment in the still kettle is high temperature and high pressure, the rail 20 in the kettle can generate the effect of expansion with heat and contraction with cold under the operating environment, when the rail 20 in the kettle expands with heat, the length of the rail can be increased, the distance between the rail and the fixed rail 31 can be shortened, and the end part of the movable rail 32 can be blocked by the rail 20 in the kettle when the movable rail rotates and deflects.

The first and

second spaces

33 and 34 are provided to allow a margin for thermal expansion of the rails 20 in the autoclave due to the operation of the autoclave. The first intervals 33 and the second intervals 34 are staggered on the track, and the support for the wheels of the steam-curing trolley is continuous, so that the stability of the steam-curing trolley in the running process is not weakened.

Referring to fig. 2 again, the distances from the end surfaces of the movable rail 32 on both sides of the concave portion 321 to the bottom surface of the concave portion 321 are not uniform. The second intervals 34 on the two sides of the convex part are also staggered, so that on the basis of ensuring that the rail supports the wheels continuously, the contact area between the wheels and the rail when the wheels pass through each interval is increased, and the driving stability of the steam-curing trolley is improved.

Referring to fig. 1 again, the movable trolley 35 is disposed below the connecting rail 30, the movable trolley 35 is provided with a first supporting column 351 and a second supporting column 352, one end of the first supporting column 351 is connected to the movable trolley 35, the other end of the first supporting column is connected to the fixed rail 31, the second supporting column 352 is disposed below the movable rail 32, and when the movable rail 32 rotates to be flush with the fixed rail 31, the lower portion of the movable rail abuts against the top of the second supporting column 352. A slide rail 36 is arranged between the kettle front rail 10 and the kettle inner rail 20, the slide rail 36 extends along the direction vertical to the kettle front rail 10 or the kettle inner rail 20, and the movable trolley 35 is arranged on the slide rail 36 in a sliding manner. In order to ensure that the connecting track 30 cannot move relative to the inner kettle track 20 and the outer kettle track when the steam-curing trolley enters the still kettle through the connecting track 30, the connecting track 30 is respectively connected with the front kettle track 10 and the inner kettle track 20 through connecting pins 37.

When the steam-curing trolley is fully loaded with steam-adding bricks and enters the still kettle, the movable trolley 35 is pushed to return and slide to the front of the still kettle, so that the fixed rail 31 is aligned with the front rail 10 of the still kettle, the connecting pin 37 is inserted, the movable rail 32 is rotated to be opened, the movable trolley is driven to rotate relative to the fixed rail 31 to be flush with the inner rail 20 of the still kettle, the convex part is inserted into the concave part 321, and the connecting pin 37 is inserted, so that the butt joint work of the front rail 10 of the still kettle and the inner rail 20 of the still kettle is completed. At the moment, the steam-curing trolley can smoothly enter the still kettle through the device.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
