Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a steel bar installation and positioning device for a large cylindrical granary. Background Art

[0002] A cylindrical granary refers to a facility designed with a cylindrical structure for storing grain. This type of granary usually has a large capacity and a sturdy and durable structure, which can effectively prevent the grain from getting damp, moldy and worm-eaten, ensuring the quality and safety of the grain. The following are the specific functions of a cylindrical granary:

[0003] Large-capacity storage: Due to its unique cylindrical design, the cylindrical granary can provide a large storage space to meet the storage needs of a large amount of grain. This is of great significance for ensuring food supply and stabilizing food prices. Moisture-proof and mildew-proof: The wall of the cylindrical granary is usually made of waterproof materials such as steel plates or concrete, which can effectively prevent the intrusion of external moisture and keep the warehouse dry. At the same time, the warehouse can also be equipped with a ventilation system to further reduce humidity and prevent grain from mold and deterioration. Insect and rodent-proof: The cylindrical granary has excellent sealing performance, which can effectively prevent the intrusion of insects and rodents and protect grain from loss. This is crucial to maintaining the hygiene and quality of grain. Easy to manage: The structural design of the cylindrical granary makes it easier to enter, exit and manage grain. For example, a dust suction device can be set on the top of the silo to facilitate cleaning of dust in the silo; a measuring hole and a lifting hook can be set on the silo wall to facilitate measuring the amount of grain and lifting operations. Significant economic benefits: Although the initial investment of the cylindrical granary is relatively high, in the long run, the economic benefits it brings are obvious. By reducing grain losses and improving storage efficiency, cylindrical grain silos can save grain companies a lot of costs and improve their market competitiveness.

[0004] However, when the existing technology is actually used, the traditional method of installing and positioning steel bars in large cylindrical granaries mainly relies on manual installation operations, which has many disadvantages. First, it is difficult to guarantee accuracy. Due to errors in manual measurement and operation, the actual position of the steel bar deviates greatly from the designed position, often exceeding the allowable range. This will not only weaken the structural strength of the granary, but may also cause cracks and deformations due to uneven local force during subsequent use, seriously affecting the service life of the granary and the safety of grain storage. Secondly, during the traditional steel bar installation and positioning process, construction personnel need to repeatedly measure and adjust, which consumes a lot of time and manpower. Moreover, due to the large circumference and height dimensions of large cylindrical granaries, the installation and construction of steel bars is difficult, which further reduces the construction efficiency, extends the entire granary construction period, and increases the construction cost.

[0018] When the mobile trailer of the present invention remains stable, the electromagnetic suction cup is controlled to be turned on. When the electromagnetic suction cup is turned on, the arc-shaped opening is cooperated to magnetically fix the steel bar to be installed. When the steel bar is magnetically fixed, the support electric telescopic rod is controlled to be turned on. When the support electric telescopic rod is turned on, the support shaft is driven to rotate through the support connecting rod. When the support shaft rotates, the support platform is driven to swing upward. When the support platform swings upward, the steel bar fixed by the magnetic attraction is synchronously driven to swing upward. When the steel bar fixed by the magnetic attraction swings upward, the electric telescopic rod is controlled to be turned on and adjusted. When the electric telescopic rod is adjusted and turned on, the installation connecting rod is driven to move linearly inside and outside. When the installation connecting rod moves linearly inside and outside, the steel bar fixed by the magnetic attraction is synchronously driven to perform internal and external installation positioning movement adjustment. After the steel bar is positioned and installed to the desired position, the electromagnetic suction cup is controlled to be turned off.

The swing electric telescopic rod is controlled to start. When the swing electric telescopic rod is turned on, the swing platform is driven to swing left and right in sequence. When the swing platform swings left and right, the steel bars fixed by the magnet are synchronously driven to swing left and right over a large range for adjustment. Thus, the steel bars are installed and positioned, and it is convenient to adjust the installation and positioning position linearly upward and swing left and right over a large range.

[0020] When the adjusting motor is turned on, the present invention will drive the adjusting seat to move outward or inward in a straight line synchronously in sequence. When the adjusting seat moves outward or inward in a straight line synchronously, it will drive the adjusting electric telescopic rod to move outward or inward in a straight line synchronously. When the adjusting electric telescopic rod moves outward or inward in a straight line synchronously, it will drive the installing connecting rod to move outward or inward in a straight line synchronously. When the installing connecting rod moves outward or inward in a straight line synchronously, it will synchronously drive the steel bars fixed by magnetic attraction to move outward or inward in a straight line synchronously to adjust the installation spacing.

[0035] When the present invention is in use, the mobile trailer 1 is towed and moved by the traction frame 101 in cooperation with the external traction equipment. When the mobile trailer 1 is towed and moved to the installation position of the steel bars of the large cylindrical granary, the first electric telescopic rod 102 is controlled to be opened. When the first electric telescopic rod 102 is opened, it will drive the supporting roller 103 to move linearly downward.

When the lifting platform 3 moves linearly upward, it will synchronously drive the steel bar fixed by the magnet to move linearly upward for adjustment. By controlling to open the swing electric telescopic rod 403, when the swing electric telescopic rod 403 is turned on, it will drive the swing shaft 401 to rotate through the swing connecting rod 402. When the swing shaft 401 rotates, it will drive the swing platform 4 to swing left and right. When the swing platform 4 swings left and right, it will synchronously drive the steel bar fixed by the magnet to swing left and right in a large range, thereby realizing the installation and positioning of the steel bar, while facilitating the installation and positioning position of the upward linear and large-range left and right swing adjustment.

[0038] At the same time, by controlling to turn on the adjusting motor 405, when the adjusting motor 405 is turned on, it will drive the first adjusting sprocket 406 to rotate. When the first adjusting sprocket 406 rotates, it will drive the second adjusting sprocket 407 to rotate through the chain transmission. When the second adjusting sprocket 407 rotates, it will drive the adjusting screw rod 408 to rotate, and the outer curved threads at both ends of the adjusting screw rod 408 are in opposite directions, so that when the adjusting screw rod 408 rotates, it will drive the adjusting seat 409 to move outward or inward in a straight line synchronously through the screw nut transmission. When the adjusting seat 409 moves outward or inward in a straight line synchronously, it will drive the adjusting electric telescopic rod 410 to move outward or inward in a straight line synchronously. When the adjusting electric telescopic rod 410 moves outward or inward in a straight line synchronously, it will drive the installation connecting rod 5 to move outward or inward in a straight line synchronously. When the installation connecting rod 5 moves outward or inward in a straight line synchronously, It will synchronously drive the steel bars fixed by the magnet to synchronously move outward or inward in a straight line to adjust the installation spacing. The installation motor 502 is turned on by control. When the installation motor 502 is turned on, it will drive the installation gear 503 to rotate. When the installation gear 503 rotates, it will engage and drive the installation toothed disc 504 to rotate. When the installation toothed disc 504 rotates, it will drive the installation shaft 501 to rotate. When the installation shaft 501 rotates, it will drive the mounting seat 505 to swing left and right. When the mounting seat 505 swings left and right, it will drive the electromagnetic suction cup 506 to swing left and right. When the electromagnetic suction cup 506 swings left and right, it will synchronously drive the steel bars fixed by the magnet to swing in a small range for adjustment. Therefore, while realizing the installation and positioning of the steel bars, it is convenient to synchronously move outward or inward in a straight line to adjust the installation spacing of the steel bars and swing left and right in a small range to adjust the installation positioning angle of the steel bars.
