Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary device for pouring concrete for basement roof slabs. Background Technology
[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various types of building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. Concrete pouring is an indispensable process in construction engineering.
[0003] A concrete pouring auxiliary device, disclosed in publication number CN 214365010 U, includes two sets of crossbeams. A slide rail is mounted on the upper surface of each crossbeam. A connecting plate spans the two sets of crossbeams above the crossbeams. A pulley is located below the connecting plate and rests on the slide rail. A storage box is positioned above the connecting plate, containing a push rod with a boss fixed to its lower end. A discharge port is located below the storage box, and the boss engages with the discharge port. This invention is applicable to concrete pouring. By using a push rod and a boss within the storage box, the height of the boss can be controlled to regulate the concrete discharge rate, improving the device's applicability. It also enables automatic discharge, eliminating the need for manual guidance via a flexible hose, reducing manual labor intensity, and preventing potential hazards.
[0004] However, the above-mentioned device still has some shortcomings in use. Its structural design lacks flexibility in terms of height adjustment and horizontal position adjustment, making it difficult to adapt to the construction needs of different heights and areas when pouring the basement roof slab. At the same time, the fixing method of the pouring pipe is relatively simple, which may cause shaking in complex construction environments, affecting the pouring accuracy. Utility Model Content

[0013] Compared with existing technologies, this utility model provides an auxiliary device for pouring concrete for basement roof slabs, which has the following advantages: In use, the device is moved to the location via a push handle and casters on the base plate. The discharge end of the concrete pouring pipe passes between the two clamps of the connecting ring. The screw is then rotated to clamp the pouring pipe. The rotation of the first motor drives the first and second bevel gears, thereby raising and lowering the screw rod, threaded sleeve, connecting ring, and pouring pipe, adjusting their height to suit different pouring positions. Simultaneously, the rotation of the second motor drives the worm gear and worm wheel, which in turn rotate the rotating rod, connecting disc, connecting ring, and pouring pipe, adjusting their position and broadening its applicability. The device securely and reliably fixes the pouring pipe with clamps and screws. By utilizing motors and bevel gears to achieve the raising, lowering, and rotation of the pouring pipe, the height and position can be flexibly adjusted to meet different pouring needs, expanding its applicability and improving construction convenience and efficiency.
