A high-pressure steam-curing preparation device for autoclaved aerated concrete blocks

Abstract

The present invention relates to the technical field of autoclaved aerated concrete block processing equipment, and particularly to a high-pressure steam curing preparation device for autoclaved aerated concrete blocks. The autoclaved aerated concrete blocks are stacked and transported by using a transport trolley, and are guided and transported along a movable track that is elastically extended outward and extends out of the outer end of a high-pressure steam curing kettle. When the transport trolley reaches a cross baffle, it pushes the cross baffle and the movable track to move into the kettle. When the movable track is completely inserted into the high-pressure steam curing kettle, it pushes the cross baffle to rotate to transport the blocks deep into the kettle. The relaxed movable track is elastically reset to allow the next transport trolley to guide the blocks into the kettle. Each transport trolley slides in reverse along the fixed guide rail and the movable track in turn, pushing the cross baffle to rotate in reverse to exit the kettle. This solves the problems of difficult direction control, time-consuming and labor-intensive operation of the transport trolley on site, or frequent assembly and disassembly of the guide rail, which is cumbersome to operate.

Description

Technical Field

[0001] The invention relates to the technical field of autoclaved aerated concrete block processing equipment, in particular to a high-pressure steam-curing preparation device for autoclaved aerated concrete blocks. Background Art

[0002] As a new type of building material, autoclaved aerated concrete blocks generally go through the following processing steps: batching, mixing, injection molding, demoulding, cutting, and autoclaving. In the existing autoclave curing step, a transport trolley is used to transport the cut autoclaved aerated concrete blocks in stacks, and multiple blocks on the trolleys are pushed into the autoclave for autoclaving in sequence. The autoclave is provided with a fixed guide rail for guiding the transport trolley into the autoclave along the fixed guide rail. However, if the fixed guide rail is limited to the autoclave, the transport trolley for stacking blocks is large in size and weight, and it is difficult to control the direction during on-site operation, and it is time-consuming and laborious to accurately guide the transport trolley into the autoclave. Moreover, if the fixed guide rail is detachably constructed and extended out of the autoclave, the guide rail needs to be frequently assembled and disassembled during on-site operation to close the autoclave door for autoclave curing, which is cumbersome and affects the efficiency of continuous and efficient autoclave preparation of autoclaved aerated concrete blocks. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide an autoclaved aerated concrete block high-pressure steam curing preparation device to solve the problem that if the fixed guide rails are limited to the high-pressure steam curing autoclave, the direction of the transport trolley for stacking the blocks is difficult to control during on-site operation, and accurately guiding them into the autoclave is time-consuming and labor-intensive. If the fixed guide rails are detachably constructed and extended out of the high-pressure steam curing autoclave, the guide rails need to be frequently assembled and disassembled in order to close the autoclave door for closed steam curing, which is cumbersome to operate and affects the efficiency of the continuous and efficient high-pressure steam curing preparation of autoclaved aerated concrete blocks.

[0004] Based on the above objectives, the present invention provides an autoclaved aerated concrete block autoclave preparation device, comprising an autoclave and a transport trolley for stacking and transporting the blocks, wherein a fixed guide rail is laid in the autoclave, and the transport trolley is guided into the autoclave along the fixed guide rail, and further comprising:

[0005] The movable track is elastically connected to one end of the fixed guide rail. In the initial state, the movable track is elastically extended outwards through the outer end of the autoclave to guide the transport trolley into the autoclave.

[0006] The cross baffle is erected in the middle of the movable track and is rotatably connected to the movable track. When the cross baffle is rotated and erected, it is used to abut and block the transport trolley. When the movable track passes out of the high-pressure autoclave, the cross baffle maintains a unidirectional rotation state toward the outer end of the high-pressure autoclave. When the movable track is completely inserted into the high-pressure autoclave, the cross baffle is in a bidirectional rotation state along the length direction of the movable track.

[0007] Preferably, the fixed guide rail is a circular tube arranged parallel to the bottom end of the autoclave, and the movable track is a circular tube arranged along the same length direction as the fixed guide rail.

[0008] Preferably, the bottom end of the transport trolley is provided with a guide rail groove wheel for clamping on the movable rail and guiding the sliding of the upper end of the fixed guide rail.

[0009] Preferably, the front end of the fixed guide rail is designed to be a hollow structure, one end of the movable rail is inserted into the hollow interior of the fixed guide rail, and a first elastic member is connected between the movable rail and the hollow interior of the fixed guide rail.

[0010] Preferably, a groove is provided in the middle of the movable track, the bottom end of the cross baffle is rotatably connected to the bottom end of the groove, a stop block is provided in the groove close to the fixed guide rail, and a second elastic member is connected to the end of the groove away from the fixed guide rail, which is used to elastically push the cross baffle to rotate upright so that the cross baffle is against the stop block for limiting the position.

[0011] Preferably, the groove is designed to be in a V-shape with an open end facing upward.

[0012] Preferably, a bottom groove is provided at the bottom end of the autoclave, and a third elastic member is provided in the bottom groove. When the movable track is completely inserted into the autoclave, the stopper moves downward to pass through the bottom groove and compress the third elastic member.

[0013] Preferably, a plurality of rolling elements are connected to the bottom end of the movable track for rolling and sliding along the ground, wherein at least one rolling element is connected to the bottom end of the stopper.

[0014] The beneficial effects of the present invention are as follows: a movable track is elastically connected to one end of a fixed guide rail, a cross baffle is vertically provided in the middle of the movable track, and a transport trolley is used to stack and transport the cut autoclaved aerated concrete blocks, and the blocks are guided and transported along the movable track elastically penetrating the outer end of the high-pressure autoclave. When the movable track passes through the outside of the high-pressure autoclave, the cross baffle keeps rotating in a unidirectional manner toward the outer end of the high-pressure autoclave, so that when the transport trolley reaches the cross baffle, it pushes the cross baffle and the movable track to move into the autoclave until the movable track is completely inserted into the high-pressure autoclave. The plate is in a state of bidirectional rotation along the length direction of the movable track, that is, it continues to push the transport trolley to push the cross baffle to rotate so as to transport it deep into the autoclave. The relaxed movable track is re-springing and reset to allow the next transport trolley to guide it into the autoclave, thereby pushing multiple trolleys of building blocks into the high-pressure steam curing autoclave for steaming in sequence. When the building blocks are taken out of the autoclave after steaming, each transport trolley slides in the opposite direction along the fixed guide rail and the movable track in sequence, pushing the cross baffle to rotate in the opposite direction to take them out of the autoclave. This solves the problems of difficult direction control, time-consuming and labor-intensive operation of the transport trolley on site, or frequent assembly and disassembly of the guide rails, which is troublesome to operate.

[0029] like Figures 1 to 9 As shown, a high-pressure steam-curing preparation device for autoclaved aerated concrete blocks includes a high-pressure steam-curing kettle 1 and a transport trolley 3 for stacking and transporting blocks 2. A fixed guide rail 4 is laid in the high-pressure steam-curing kettle 1, and the transport trolley 3 is guided into the kettle along the fixed guide rail 4. The high-pressure steam-curing kettle also includes a movable track 5 elastically connected to one end of the fixed guide rail 4. In the initial state, the movable track 5 elastically penetrates the outer end of the high-pressure steam-curing kettle 1 to guide the transport trolley 3 into the kettle. A cross baffle 6 is erected in the middle of the movable track 5, and the cross baffle 6 is rotatably connected to the movable track 5. When the cross baffle 6 is rotated and erected, it is used to abut and block the transport trolley 3. When the movable track 5 passes through the outside of the high-pressure steam-curing kettle 1, the cross baffle 6 maintains a unidirectional rotation state toward the outer end of the high-pressure steam-curing kettle 1. When the movable track 5 is completely inserted into the high-pressure steam-curing kettle 1, the cross baffle 6 is in a bidirectional rotation state along the length direction of the movable track 5.

[0030] When the movable rail 5 is fully inserted into the autoclave 1, the cross baffle 6 is in a bidirectional rotation state along the length direction of the movable rail 5, so that the cut autoclave aerated concrete blocks 2 can be stacked and transported. When the moving rail 5 is fully inserted into the autoclave 1, the cross baffle 6 is in a state of bidirectional rotation along the length direction of the movable rail 5, that is, it continues to push the transport trolley 3 to push the cross baffle 6 to rotate, so as to transport it deeper into the autoclave. The relaxed movable rail 5 is resiliently reset to the outside to guide the next transport trolley 3 into the autoclave, thereby pushing multiple building blocks into the autoclave at intervals for steaming. When the building blocks are steamed out of the autoclave, each transport trolley 3 slides in the opposite direction along the fixed guide rail 4 and the movable rail 5 in turn, pushing the cross baffle 6 to rotate in the opposite direction to exit the autoclave, thereby solving the problem of difficult direction control, time-consuming and labor-intensive, or frequent assembly and disassembly of the guide rails, and troublesome operation when the transport trolley 3 is operated on site.

[0031] Specifically, the rear end of the transport trolley 3 is provided with a hanging ear, so that in actual operation, a long rod is hooked on the hanging ear to push and pull the transport trolley 3. Figure 5 As shown, a closing kettle door 13 is hinged at the top of the autoclave 1 .

[0032] In an embodiment of the present invention, Figures 1 to 4 As shown, the fixed guide rail 4 is a circular tube parallel to both sides of the bottom end of the autoclave 1, and the movable track 5 is a circular tube arranged along the same length direction of the fixed guide rail 4. Preferably, the circular tube can be made of steel tube.

[0033] In an embodiment of the present invention, Figure 9 As shown, the bottom end of the transport trolley 3 is provided with a guide rail groove wheel 7 for clamping on the movable rail 5 and the upper end of the fixed guide rail 4 to guide sliding.

[0034] In an embodiment of the present invention, Figures 1 to 4As shown, the front end of the fixed guide rail 4 is designed to be a hollow structure, one end of the movable rail 5 is inserted into the hollow interior of the fixed guide rail 4, and a first elastic member is connected to the hollow interior of the fixed guide rail 4. Specifically, the first elastic member can be a component such as a spring, so as to push the movable rail 5 outward to penetrate the outer end of the high-pressure steam curing autoclave 1 in the initial state.

[0035] In an embodiment of the present invention, Figures 6 to 8 As shown, a groove 51 is provided in the middle of the movable track 5, and the bottom end of the cross baffle 6 is rotatably connected to the bottom end of the groove 51. A stopper 8 is provided at one end of the groove 51 close to the fixed guide rail 4, and a second elastic member 9 is connected to one end of the groove 51 away from the fixed guide rail 4. The second elastic member 9 can be a component such as a spring, which is used to elastically push the cross baffle 6 to rotate and stand upright, so that the cross baffle 6 is pressed against the stopper 8 for limiting the position. Therefore, when the movable track 5 passes through the outside of the autoclave 1, the cross baffle 6 remains in a rotating upright position and can only rotate in one direction toward the outer end of the autoclave 1 to allow the transport trolley 3 to freely exit the autoclave. When entering the autoclave, the cross baffle 6 and the movable track 5 are pushed to move into the autoclave.

[0036] In an embodiment of the present invention, Figures 6 to 8 As shown, the groove 51 is designed to be in a V-shaped shape with an open end facing upward. When the transverse baffle 6 rotates toward both ends, it is retracted into the V-shaped groove 51 .

[0037] In an embodiment of the present invention, Figure 8 As shown, a bottom groove 10 is provided at the bottom end of the autoclave 1, and a third elastic member 11 is provided in the bottom groove 10. The third elastic member 11 can be made of components such as a spring. When the movable track 5 is completely inserted into the autoclave 1, that is, the stop block 8 moves to the position of the bottom groove 10 and continues to push the transport trolley 3. The transport trolley 3 pushes the cross baffle 6, so that the cross baffle 6 pushes the stop block 8. The stop block 8 is pushed downward and penetrates into the bottom groove 10, and compresses the third elastic member 11, so that the transport trolley 3 passes over the cross baffle 6 and continues to be transported deep into the autoclave. The third elastic member 11 can be made of components such as a spring. After the transport trolley 3 passes over the cross baffle 6 and is transported deep into the autoclave, the third elastic member 11 rebounds and pushes the stop block 8 to move up and reset. The first elastic member pushes the movable track 5 outward and penetrates the outer end of the autoclave 1 to allow the next transport trolley 3 to be transported into the autoclave.

[0038] In an embodiment of the present invention, Figures 6 to 8 As shown, a plurality of rolling members 12 are connected to the bottom end of the movable track 5 for rolling and sliding along the ground, wherein at least one rolling member 12 is connected to the bottom end of the block 8. Optionally, the rolling member 12 can be a ball movably connected to the bottom end of the movable track 5 to facilitate flexible rolling transportation.

[0039] In the autoclaved aerated concrete block high-pressure steam curing preparation device disclosed in the present invention, when in use, a movable track 5 is elastically connected to one end of the fixed guide rail 4, and a cross baffle 6 is vertically provided in the middle of the movable track 5. The cross baffle 6 is rotatably connected to the movable track 5. When the cross baffle 6 is rotated and erected, it is used to abut and block the transport trolley 3. The transport trolley 3 is used to stack and transport the cut autoclaved aerated concrete blocks, and guide the transport along the movable track 5 that is elastically penetrated out of the outer end of the high-pressure steam curing kettle 1. Since the movable track 5 penetrates the outside of the high-pressure steam curing kettle 1, the cross baffle 6 maintains a unidirectional rotation state toward the outer end of the high-pressure steam curing kettle 1, thereby When the transport trolley 3 reaches the cross baffle 6, it pushes the cross baffle 6 and the movable track 5 into the autoclave. Until the movable track 5 is completely inserted into the high-pressure steaming autoclave 1, the cross baffle 6 is in a two-way rotation state along the length direction of the movable track 5, that is, it continues to push the transport trolley 3 to push the cross baffle 6 to rotate to transport it deep into the autoclave. The relaxed movable track 5 is re-springing and reset to allow the next transport trolley 3 to guide it into the autoclave, thereby pushing multiple car blocks into the high-pressure steaming autoclave at intervals for steaming. When the blocks are steamed out of the autoclave, each transport trolley 3 slides in the opposite direction along the fixed guide rail 4 and the movable track 5 in turn, pushing the cross baffle 6 to rotate in the opposite direction to get out of the autoclave.
