Description

Technical Field

[0001] This utility model relates specifically to a self-elevating support system for door groove embedded parts. Background Technology

[0002] In water conservancy and hydropower engineering construction, the pre-embedding of gate slot components is a crucial step in gate installation, and its construction quality directly affects the gate's operational performance and the overall safety of the project. Traditional gate slot component pre-embedding typically employs a two-stage installation and pouring method. This method suffers from problems such as difficulty in controlling component positioning accuracy, low construction efficiency, long construction period, high labor intensity, and high risks associated with high-altitude operations. To address these issues, through engineering practice and technological innovation, a self-elevating support system for the one-stage installation of gate slot components has been invented. With the assistance of this system, the one-stage installation of gate slot components can be achieved. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Reference Figure 1-7 The specific embodiment adopts the following technical solution: a self-elevating support system for door slot embedded parts, including a truss support structure 1, a magnetic adjustment structure 2, a support roller structure 3, a lifting structure 4, a measurement and monitoring system 5, and a work platform 6. Multiple work platforms 6 are arranged between the truss support structures 1. A lifting structure 4 is arranged in the truss support structure 1. Multiple magnetic adjustment structures 2, support roller structures 3, and measurement and monitoring systems 5 are arranged on the truss support structure 1.

[0024] It is worth noting that the truss support structure 1 is composed of welded I-beams, square tubes, angle steel, and round tubes. The entire truss support structure is assembled in the factory and then welded as a whole on site. The height of the truss support structure is twice the size of a single section of the embedded parts, typically 10-12m. Each operating platform is 2.4m high, facilitating personnel to work from the platform. The operating platforms are connected by stairs, and all operating platforms are interconnected.

[0025] It is worth noting that the magnetic adjustment structure 2 includes a magnetic adjustment rod 21, a fine-tuning gear 22, a permanent magnet chuck 23, and a first U-shaped screw fixing structure 24. The magnetic adjustment rod 21 is connected to the permanent magnet chuck 23 by bolts, and the magnetic adjustment rod 21 is connected to the truss support structure 1 by the first U-shaped screw fixing structure 24. By rotating the fine-tuning gear 22, the position of the permanent magnet chuck can be finely adjusted, thereby achieving precise positioning of the embedded part. An embedded part main rail 7 is installed on the outside of the magnetic adjustment structure 2, and an embedded part reverse rail 8 is hoisted thereon.

[0026] It is worth noting that the supporting roller structure 3 includes an adjustable roller support 31, a roller 32, and a second U-shaped screw fixing structure 33. The roller 32 is fixed to the adjustable roller support 31 by bolts. The adjustable roller support 31 is connected to the truss support structure 1 through the second U-shaped screw fixing structure 33. A measurement and monitoring system 5 is set on the main working surface of the embedded part. The measurement and monitoring system includes an angle measurement sensor 51 and a displacement measurement sensor 52, and both the angle measurement sensor 51 and the displacement measurement sensor 52 are connected to the monitoring platform.

[0027] It is worth noting that the lifting structure 4 includes a steel strand jack 41, a lifting guide pulley 42, a lifting steel strand 43, and a steel wire rope 44. The steel strand jack 41 is connected to the steel wire rope 44 through the lifting steel strand 43, and the steel wire rope 44 is connected to the lifting lug 45 on the embedded part through the lifting guide pulley 42.

[0029] The self-elevating support system for the first-phase installation of the slot embedded parts in this specific embodiment is a truss support structure made of profiles, possessing high rigidity and stability. In the first-phase pre-embedding construction of the slot embedded parts, the self-elevating support system serves as the positioning and fixing device for the slot embedded parts, providing accurate positioning benchmarks and support structures. By installing the slot embedded parts onto the self-elevating support system, forming an integrated structure, the embedded parts can maintain a stable position and posture during concrete pouring, and their status can be monitored continuously throughout the pouring process.

[0030] The positioning reference surface of the self-elevating support system is precisely machined and measured according to the design dimensions and positions of the gate slot embedded parts, ensuring that each positioning surface of the formwork is consistent with the design positions of the embedded parts. During construction, the position and elevation of the self-elevating support system are precisely adjusted and controlled using measuring instruments to meet design requirements. Then, the gate slot embedded parts are installed on the self-elevating support system according to design requirements. The positioning surfaces and fixing devices of the formwork are used to accurately position and fix the embedded parts, ensuring that parameters such as position, elevation, and verticality of the embedded parts meet design requirements.

[0031] The process flow for the self-elevating support system used in the first phase of the door slot embedded parts installation is as follows: Construction preparation → Overall assembly of the self-elevating support system → Installation of the first main rail section (installation of embedded main rail 7) → Hoisting and positioning of the self-elevating support system → Horizontal adjustment of the self-elevating support system → Positioning of the magnetic adjustment structure for the main rail → Hoisting of the first reverse rail section (installation of embedded reverse rail 8) → Positioning of the magnetic adjustment structure for the reverse rail → Overall reinforcement and inspection and acceptance → Installation of the measurement and monitoring system → Concrete pouring → Re-measurement of the door slot embedded parts support → Adjustment and positioning of the support roller structure → Contraction of the magnetic adjustment structure → Overall lifting of the self-elevating support system → Fixing of the self-elevating support system → Positioning of the magnetic adjustment structure (at the location of the poured concrete) → Repeat the above process for construction.
