Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, and in particular to a method for on-site assembly of a banana screening box and an auxiliary assembly device. Background Technology

[0002] As a key process equipment in industries such as coal mining, chemical industry, and construction, the banana screen ensures the continuous operation of the production system. During the production process, harsh operating environments, high-cycle fatigue damage, high-load operation, and the impact of materials on the equipment lead to the need for periodic maintenance or replacement of the banana screen.

[0003] However, banana screens are often installed on higher floors of factory buildings, and the installation of banana screens usually takes place during the construction of the factory building, with the equipment hoisted into the building and installed before the roof is sealed. This makes it difficult to complete the overall hoisting of banana screens when replacing them later due to site conditions. Summary of the Invention

[0004] To address the above problems, embodiments of the present invention provide a method for on-site assembly of a banana sieve box and an auxiliary assembly device.

[0005] One aspect of this invention provides a method for on-site assembly of a banana sieve box, comprising:

[0006] The auxiliary assembly device is cut according to the design dimensions of the banana screen. The auxiliary assembly device includes: a horizontal mounting beam and a vertical mounting beam.

[0007] The auxiliary assembly device and the various loose parts of the banana screen are hoisted to the on-site installation position of the banana screen. The banana screen includes: the left side plate mounting plate of the screen machine, the right side plate mounting plate of the screen machine, the screen machine crossbeam, the screen support angle steel, and the screen plate.

[0008] Multiple longitudinal installation beams are placed in parallel on a horizontal ground, and multiple transverse installation beams are fixed in parallel on the multiple longitudinal installation beams.

[0009] Hoist the left side panel mounting plate of the screening machine onto the horizontal mounting beam and fix it. During the fixing process, ensure the verticality of the left side panel mounting plate of the screening machine. Hoist the right side panel mounting plate of the screening machine onto the horizontal mounting beam and fix it. During the fixing process, ensure the verticality of the right side panel mounting plate of the screening machine and adjust the distance between it and the left side panel mounting plate of the screening machine to meet the design dimensions of the banana screening machine.

[0010] Hoist the screen beam between the left side plate mounting plate and the right side plate mounting plate of the screen machine and install it. Install the screen support angle steel on the screen beam and install the screen plate on the screen support angle steel.

The mounting holes include lower mounting holes for screwing with the side plate mounting bend.

[0016] During the process of hoisting and fixing the left and right side plate mounting bends of the screening machine onto the horizontal mounting beam, first screw the side plate mounting bends into the lower mounting holes of the left and right side plate mounting bends of the screening machine. Then, hoist the left and right side plate mounting bends of the screening machine onto the horizontal mounting beam, adjust their positions so that the side plate mounting bends are positioned with the corresponding side plate connection holes, and then screw the side plate mounting bends onto the horizontal mounting beam.

[0017] Optionally, the auxiliary assembly device also includes: an adjustable support rod, an upper support base, and a lower support base, wherein the two ends of the adjustable support rod are hinged to the upper support base and the lower support base respectively; the horizontal mounting beam is also drilled with a support connection hole for screwing the lower support base; the mounting hole also includes an upper mounting hole for screwing the upper support base.

[0018] During the process of ensuring the verticality of the mounting plates on the left and right sides of the screening machine, the lower support seat is screwed onto the horizontal mounting beam, and the upper support seat is screwed into the upper mounting hole. The extension and retraction of the adjustable support rod is adjusted to ensure the verticality of the mounting plates on the left and right sides of the screening machine.

[0019] Optionally, the auxiliary assembly device may also include: a removable pad;

[0020] During the process of screwing the side plate mounting plates into the lower mounting holes of the left and right side plate mounting plates of the screening machine, a removable pad is inserted between the side plate mounting plates of the left or right side plate and the side plate mounting plate to facilitate the subsequent hoisting of the screening machine crossbeam between the left and right side plate mounting plates.

[0021] Optionally, during the installation process of hoisting the screen beam between the left side plate mounting bend and the right side plate mounting bend of the screen machine, the mounting holes of the screen beam are pre-fixed to the left side plate mounting bend and the right side plate mounting bend of the screen machine using positioning pins on the diagonal lines of the flange.

[0022] After pre-fixing, remove the removable pad strip, use rivets to tighten the mounting holes in the screen beam that are not equipped with positioning pins, remove the positioning pins, and tighten the remaining mounting holes with rivets.
