DETAILED DESCRIPTION

[0025] The following non-limiting examples are used to illustrate the present invention.

[0026] Example 1

[0027] refer to Figure 1 to Figure 4 As shown, a shallow circular silo roof telescopic concrete pouring auxiliary device includes a movable bracket 1, a lifting mechanism 2, a rotating drive mechanism 3, a pouring silo body 4 and a telescopic mechanism 5.

[0028] The existing device (publication (announcement) number - CN218509047U) discloses a shallow circular silo roof concrete pouring auxiliary device. The movable bracket 1, lifting mechanism 2 and rotating drive mechanism 3 in this application document adopt the same technical means in this prior art, and this technical means will not be repeated here one by one.

[0029] Based on this existing subject, this application makes further improvements, please refer to the following disclosed technology for details; to solve the technical problems existing in this existing technology, such as the above background technology disclosed that "although the above design realizes the uniform casting of the shallow circular warehouse roof during use, and enhances the casting effect of the shallow circular warehouse roof, the casting range of the shallow circular warehouse roof is limited due to the fixed integrated design of the casting bin, resulting in insufficient casting, reducing the practical effect of the device, and making it difficult to meet the actual use needs", in terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a telescopic mechanism 5 and a marking mechanism 6 are added to this application document, and the electrical equipment involved in this product is powered by an external power supply.

[0030] The accessories used by the movable bracket 1, the lifting mechanism 2 and the rotating drive mechanism 3 are disclosed by the existing device, and the use effect thereof can be referred to the publication number CN218509047U (that is, the "underframe, movable wheels, columns, push rod motors, movable plates, connecting columns, limit frames, limit frames, support plates, positioning bolts, top frames, transmission racks, transmission frames, connecting plates, casting bins, transmission shafts, transmission gears and drive motor components disclosed in this prior art").

[0031] The mobile bracket 1 drives the entire device to move, so that the position of the device can be directly changed, the device can be moved to another site, and the pouring position can be adjusted. The mobile bracket 1 is provided with a vertically movable lifting mechanism 2, which drives the rotating drive mechanism 3, the pouring bin body 4 and the telescopic mechanism 5 to adjust the vertical position to ensure that the operation is performed above the bin roof.

[0032] The lifting mechanism 2 is provided with a rotary drive mechanism 3 that moves in an arc. The rotary drive mechanism 3 is driven to rotate along a certain center of a circle, preferably the center of a circle where the wall of the shallow circular bin is located. The rotary drive mechanism 3 drives the casting bin body 4 and the telescopic mechanism 5 to rotate, so as to achieve horizontal adjustment of the casting position along the direction of the bin wall. The rotary drive mechanism 3 is provided with a telescopic mechanism 5 that moves radially. The telescopic mechanism 5 slides horizontally along the radial direction, driving the casting bin body 4 to adjust the internal and external positions, and cooperates with the rotary drive mechanism 3 to improve the overall operation span and range. The telescopic mechanism 5 is provided with a casting bin body 4, which is used to unload concrete for the final casting operation.

[0033] When this structural part is in use, the movable bracket 1 is first moved to the outer wall position of the shallow circular warehouse, and then the casting warehouse body 4 is opened to cast the top plate of the shallow circular warehouse. At the same time, the casting warehouse body 4 is lifted and lowered by starting the lifting mechanism 2 until the casting warehouse body 4 moves to a suitable height, and then the rotating drive mechanism 3 is started to drive the casting warehouse body 4 to move along the top of the shallow circular warehouse.

[0034] The telescopic mechanism 5 includes a fixed frame 501, a sliding plate 502, a frame 1 503, a sliding limit assembly, a telescopic drive assembly and a synchronous stirring assembly. The fixed frame 501 is a straight rod structure arranged horizontally in the radial direction, and the fixed frame 501 is fixedly connected to the rotary drive mechanism 3. The sliding plate 502 is a straight rod structure with an inverted U-shaped cross-section, and the sliding plate 502 slides radially on the upper part of the fixed frame 501. The frame 1 503 is an upward C-shaped structure, and the sliding plate 502 is fixedly connected to the casting bin body 4 through the frame 1 503, so that the relative slippage of the sliding plate 502 is converted into the radial movement of the casting bin body 4.

[0035] A telescopic drive assembly and a sliding limit assembly are provided between the fixed frame 501 and the sliding plate 502. The telescopic drive assembly is used to provide power for the sliding of the sliding plate 502, and the sliding limit assembly is used to provide a limit support for the sliding of the sliding plate 502. A synchronous stirring assembly is provided between the fixed frame 501 and the casting bin body 4. During the telescopic sliding, the synchronous stirring assembly converts the relative sliding between the fixed frame 501 and the casting bin body 4 into a rotational motion, and uses a rotating stirring rod to stir the concrete in the bin.

[0036] The telescopic drive assembly includes a drive member, a rack 1 506, a gear 1 507 and a frame 2 511. The frame 2 511 is a downward C-shaped structure, and the frame 2 511 is fixedly arranged above the fixed frame 501. The drive member is arranged on the frame 2 511, and a rotating gear 1 507 is installed in the frame 2 511. A transmission shaft is fixed inside the gear 1 507, and both ends of the transmission shaft are rotatably connected to the frame 2 511 through bearings. The drive member is connected to the gear 1 507, and the drive member is used to provide power for the rotation of the gear 1 507. The rack 1 506 is fixedly arranged on the upper surface of the sliding plate 502, and the gear 1 507 is meshed with the rack 1 506. Then the rotation of the gear 1 507 acts on the rack 1 506, providing a force for the rack 1 506 to slide horizontally.

[0037] The driving part includes a servo motor 510, a worm gear 508 and a worm 509. The servo motor 510 is fixed above the frame 2 511, the servo motor 510 is connected to the worm 509, the worm 509 is meshed with the worm gear 508, and the worm gear 508 is connected to the gear 1 507 through a transmission shaft. The servo motor 510 uses the worm gear and the worm gear to convert the vertical rotation into the horizontal rotation, driving the worm gear 508 and the gear 1 507 to rotate synchronously.

[0038] A worm 509 is fixed to the output end of the servo motor 510, and the other end of the worm 509 is rotatably connected to a fixed block through a bearing, and the fixed block is fixedly connected to the frame 2 511. The surface of the worm 509 is meshedly connected to a worm wheel 508, and the worm wheel 508 is fixed to the surface of the transmission shaft. The servo motor 510 is started, and the worm 509 is driven to rotate. Since the worm 509 and the worm wheel 508 are meshedly connected, the worm wheel 508 is driven to rotate, and the transmission shaft is driven to rotate through the worm wheel 508, and the gear 1 507 is driven to rotate through the transmission shaft. The coordinated use of the worm 509 and the worm wheel 508 can provide a larger transmission ratio, which makes it very useful in situations where it is necessary to significantly reduce the speed and increase the torque.

[0039] The sliding limit assembly includes a limit rod 504 and a limit block 505. The two sides of the fixed frame 501 are symmetrically provided with sliding grooves, the fixed frame 501 is provided with a limit rod 504, and the sliding plate 502 is provided with a limit block 505. The limit rod 504 and the limit block 505 are both located in the sliding groove, and the limit rod 504 and the through hole on the limit block 505 are slidably matched. That is, through the sliding guide match between the limit rod 504 and the limit block 505, and through the sliding guide match between the limit block 505 and the sliding groove, the sliding of the sliding plate 502 is guided and limited on both sides, ensuring smooth sliding and sliding accuracy.

[0040] When this structural part is in use, after the casting bin body 4 moves one circle, the servo motor 510 is started to drive the transmission shaft to rotate, and the gear 507 is driven to rotate through the transmission shaft. Since the gear 507 and the rack 506 are meshed and connected, the rack 506 is driven to move, and the sliding plate 502 is driven to move through the rack 506, so that the sliding plate 502 slides on the fixed frame 501. At the same time, it drives the limit block 505 to slide on the limit rod 504. Through the setting of the limit block 505 and the limit rod 504, the fixed frame 501 can be limited, so that the sliding plate 502 is more stable during the movement process. Through the movement of the sliding plate 502, the frame 1 503 is driven to move, and then the casting bin body 4 is driven to move through the frame 1 503, so that the casting bin body 4 can be moved horizontally. After the casting bin body 4 is moved to a certain distance, it is rotated for one circle with the cooperation of the moving bracket 1 and the rotating drive mechanism 3. Through this operation, the casting range of the shallow circular warehouse roof can be wider, and the casting operation can be realized at any position on the top of the shallow circular warehouse roof, making the overall casting more comprehensive and uniform, improving the use effect of the device, and meeting the actual use needs.

[0041] The synchronous stirring assembly includes a rack 2 512, a gear 2 513 and a stirring rod 514. The rack 2 512 is fixedly arranged inside the fixed frame 501, and the stirring rod 514 is rotatably mounted on the casting bin body 4 through a bearing. The stirring part of the stirring rod 514 is located inside the casting bin body 4, and the upper end of the stirring rod 514 is fixedly connected to the gear 2 513, and the gear 2 513 is meshed with the rack 2 512.

[0042] When the casting bin body 4 moves in the radial direction by telescopic sliding, it also drives the stirring rod 514 and the gear 2 513 to move. Since the gear 2 513 and the rack 2 512 are meshed and connected, the gear 2 513 rotates, and the stirring rod 514 is driven to rotate by the gear 2 513, so that the concrete inside the casting bin body 4 can be stirred, the uniformity of the concrete can be maintained, the separation of aggregate and slurry can be prevented, the formation of hard lumps or stratification of concrete can be prevented, and the construction quality can be guaranteed.

[0043] The mobile bracket 1 is provided with an inward and outward telescopic marking mechanism 6, and the extended marking mechanism 6 can be used to mark the moving position, distance, route, etc. of the mobile bracket 1, so as to judge whether the movement of the mobile bracket 1 is accurate, stable and complete.

[0044] The marking mechanism 6 includes a mounting seat 601, a sliding ear 602, a marking pen 603, an operating panel 604 and a spring 605. The mounting seat 601 is symmetrically fixed on both sides of the mobile bracket 1, the sliding ear 602 is vertically slidably arranged on the mounting seat 601, and the marking pen 603 is telescopically arranged on the sliding ear 602. The marking pen 603 is controlled to extend outside the warehouse wall to mark and draw lines, and the position of the mark is adjusted by the vertical sliding of the sliding ear 602, so that the marked area can be increased. An operating panel 604 is arranged at the tail end of the marking pen 603, and a spring 605 is arranged between the sliding ear 602 and the operating panel 604.

[0045] When the movable bracket 1 moves along the edge of the shallow circular bin, the marking pen 603 is moved by pressing the operating disk 604, and the spring 605 is compressed at the same time. As the marking pen 603 moves, until the marking pen 603 contacts the outer wall of the shallow circular bin, marking is performed by the marking pen 603, and at the same time, the sliding ear 602 is slid to move on the surface of the mounting seat 601, thereby increasing the marking area for easy observation later. By marking the two ends, the positions of the two ends are made corresponding after the movable bracket 1 moves a certain distance, thereby avoiding the spacing error at the two ends and causing the casting bin main body 4 to leak, thereby further improving the casting uniformity and meeting the actual use needs.

[0046] The working principle and use process of the utility model are as follows: first, the mobile bracket 1 is moved to the position of the outer wall of the shallow circular warehouse, and then the casting warehouse body 4 is opened to cast the top plate of the shallow circular warehouse, and at the same time, the casting warehouse body 4 is lifted and lowered by starting the lifting mechanism 2 until the casting warehouse body 4 moves to a suitable height, and then the rotating drive mechanism 3 is started to drive the casting warehouse body 4 to move along the warehouse roof of the shallow circular warehouse.

[0047] After driving the casting bin body 4 to move one circle, the servo motor 510 is started, which drives the worm 509 to rotate. Since the worm 509 is meshed with the worm wheel 508, the worm wheel 508 is driven to rotate, and the transmission shaft is driven to rotate through the worm wheel 508, and the gear 1 507 is driven to rotate through the transmission shaft. Since the gear 1 507 is meshed with the rack 1 506, the rack 1 506 is driven to move, and the sliding plate 502 is driven to move through the rack 1 506, so that the sliding plate 502 slides on the fixed frame 501, and at the same time drives the limit block 505 to slide on the limit rod 504. Through the setting of the limit block 505 and the limit rod 504 , it can limit the fixed frame 501, so that the sliding plate 502 is more stable during movement, and the sliding plate 502 moves, and the frame 1 503 is driven to move, and then the casting bin body 4 is driven to move through the frame 1 503, so that the casting bin body 4 can be moved horizontally. After the casting bin body 4 is moved to a certain distance, it is rotated one circle with the cooperation of the mobile bracket 1 and the rotating drive mechanism 3. Through this operation, the casting range of the shallow circular warehouse roof can be wider, and the casting operation can be realized at any position on the top of the shallow circular warehouse roof, making the overall casting more comprehensive and uniform, improving the use effect of the device, and meeting the actual use needs.

[0048] When the casting bin body 4 moves, the stirring rod 514 and the gear 2 513 are driven to move. Since the gear 2 513 and the rack 2 512 are meshed and connected, the gear 2 513 is rotated, and the stirring rod 514 is driven to rotate by the gear 2 513, so that the concrete inside the casting bin body 4 can be stirred, the uniformity of the concrete can be maintained, the separation of aggregate and slurry can be prevented, the formation of hard lumps or stratification of concrete can be prevented, and the construction quality can be guaranteed.

[0049] When the movable bracket 1 moves along the edge of the shallow circular bin, the marking pen 603 is moved by pressing the operating disk 604, and the spring 605 is compressed at the same time. As the marking pen 603 moves, until the marking pen 603 contacts the outer wall of the shallow circular bin, marking is performed by the marking pen 603, and at the same time, the sliding ear 602 is slid to move on the surface of the mounting seat 601, thereby increasing the marking area for easy observation later. By marking the two ends, the positions of the two ends are made corresponding after the movable bracket 1 moves a certain distance, thereby avoiding the spacing error at the two ends and causing the casting bin main body 4 to leak, thereby further improving the casting uniformity and meeting the actual use needs.
