Description

Technical Field

[0001] This utility model belongs to the field of T-beam construction technology and relates to a T-beam side formwork grinding and cleaning mechanism. Background Technology

[0002] The formwork system in the T-beam production line consists of three parts: side formwork, bottom formwork, and end formwork. The side formwork is fixed, while the bottom formwork is a longitudinally moving bottom formwork platform. Due to the change in beam length, the relationship between the side formwork and the end formwork is that the side formwork is wrapped around the end.

[0003] Main materials for side formwork: Stainless steel panels for the front panels and T12 steel strips for the connecting plates. Side formwork demolding method: Automated mold closing and demolding via a hydraulic system. Side formwork connection method: Beams are connected as a whole along their length using bolts, and connected as a whole along their cross-section using upper and lower tie rods. Shared side formwork method: Considering beam length variations of ±500mm for spans of 25m / 40m, the side formwork length is designed to be 26m / 40m, and the beam height is designed to be 1.75m / 2.5m. To save on formwork, prefabrication of 80-type and 160-type expansion joints is achieved by replacing movable blocks at the beam ends. Side formwork types: Side formwork is divided into center beam side formwork and edge beam side formwork. Both center beam and edge beam side formwork consist of five main parts: formwork section, bottom support, sliding block, comb plate, and platform system.

[0004] The movable bottom formwork platform consists of three main parts: the bottom formwork template, the main beam, and the longitudinal trolley. The bottom formwork template is placed directly on the main beam, and the traveling system is assembled with the main beam as a whole via connecting plates. The bottom formwork template is made of T6 steel plate, with channel steel used for longitudinal reinforcement at the bottom of the panel. The bottom formwork width is designed to be 600mm, and movable templates are designed at the bottom lifting points of the beams for easy lifting. The main beam adopts a double-section H-beam steel structure, divided into three sections, with the longest single section being 12m. The longitudinal trolley consists of four main parts: wheel boxes, wheel sets, drive unit, and motor protective cover.

[0005] End formwork: The end formwork is connected to the side formwork using a side formwork clamping method. The end formwork panel is made of T6 steel plate, and the connecting plates and reinforcing ribs are all made of T8 steel strip. The end formwork is placed directly above the bottom formwork (concrete surface), and the top surface of the end formwork has a 2% slope; sealing strips are installed at the connection points between the end formwork and the bottom and side formwork to ensure strong sealing and prevent grout leakage during prefabrication.

[0006] After the side formwork is demolded after construction, it usually needs to be manually polished. Due to its height, manual polishing is time-consuming, labor-intensive, and has poor operational safety. Utility Model Content

The vertical dust suction hood 6021 is connected to the second negative pressure dust suction device through a pipe. The second negative pressure dust suction device is installed on the electric walking mechanism 1. It uses the dust suction pipe to suction the surface of the polished side mold and then blows away the dust that is not completely suctioned. The dust suction hood has elastic contact and can also play a certain scraping role. The air jet holes are tilted backward to avoid affecting the dust suction effect.

[0047] The second blowing and dust-collecting mechanism 7 includes a horizontal dust-collecting hood 701 and a horizontal air jet pipe 702. The horizontal dust-collecting hood 701 is a strip structure, horizontally installed at the bottom of the traveling frame 102 of the electric traveling mechanism 1 and elastically in contact with the top surface of the bottom mold 5 of the traveling trolley.

The horizontal air jet pipe 702 is provided with air jet holes facing the top surface of the bottom mold of the traveling trolley. The horizontal dust-collecting hood 701 is connected to a third negative pressure dust-collecting device through a pipe. The third negative pressure dust-collecting device is installed on the traveling frame 102 of the electric traveling mechanism 1. Through the horizontal dust-collecting pipe, the surface of the bottom mold after grinding is vacuumed, and the areas that are not completely vacuumed are blown away, resulting in a thorough effect. The elastic contact of the horizontal dust-collecting hood also plays a certain scraping role.

[0048] The first negative pressure vacuuming device, the second and third negative pressure vacuuming devices can share one, and the three vacuuming circuits are controlled by different electromagnetic inventions for vacuuming control.

[0049] An operation method using the T-beam template grinding and cleaning device is as follows: After the T-beam is poured, the two T-beam side molds are moved to a set position and the bottom mold of the traveling trolley is controlled to be located between the two T-beam side molds. The T-beam template grinding and cleaning device is placed at one end of the bottom mold of the traveling trolley. The side and top grinding mechanism, the bottom grinding mechanism, and the first blowing and dust suction mechanism are started. The side and top grinding mechanism and the bottom grinding mechanism are controlled to contact the T-beam side mold and the bottom mold of the traveling trolley respectively. The electric traveling mechanism is controlled to travel at a constant speed. When traveling to one end, grinding, blowing, and dust suction are performed simultaneously during the travel. Then, the device travels in the opposite direction to perform grinding, blowing, and dust suction. The grinding, cleaning, and dust suction operations are completed after several cycles of traveling back and forth.
