Description

Technical Field

[0001] This utility model relates to the field of stage machinery and building installation engineering. Specifically, it is a lifting light frame installation base tool suitable for non-horizontal surfaces and multi-load-bearing conditions, used to solve the problems of load distribution and dynamic stability when installing light frames on the top of irregular building structures. Background Technology

[0002] Lifting lighting rigs are widely used in large spaces such as theaters and stadiums. Their installation locations are typically on the top of buildings or roof structures. These areas often have non-horizontal designs such as curved surfaces or stepped structures due to architectural aesthetic requirements, making it difficult to maintain a level foundation for the lighting rig. Furthermore, lifting lighting rigs are heavy and require frequent lifting movements, placing extremely high demands on the pressure distribution and dynamic stability of the load-bearing structure. Current technologies, especially conventional foundation fixtures, are mostly designed for factory settings (such as power equipment and assembly lines), lacking solutions specifically tailored to the unique needs of lifting lighting rigs.

[0003] For example, patent document CN206876394U discloses a general basic tooling for a power transmission test bench, which adapts to the testing needs of power components such as engines and gearboxes through modular design. However, this solution focuses on static load and power transmission and cannot meet the dynamic balance requirements during the lifting and lowering of the lamp holder. Patent document CN203256759U proposes a pre-assembled basic tooling for a crane cylindrical tower body, which relies on embedded parts and foundation filler to fix the tower body. It is suitable for vertical load-bearing structures, but it is difficult to adapt to the multi-point load distribution requirements of irregular curved surfaces on the top of buildings.

[0004] Currently, the installation of lifting light fixtures mostly adopts on-site customized welding or reinforcement support structures, which has the problems of long construction period, high cost, and difficulty in ensuring uniform load distribution. Therefore, there is an urgent need for a basic tooling solution that can adapt to non-horizontal installation surfaces, realize automatic weight distribution at multiple points, and dynamically maintain the stability of the light fixture. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable support module and a linkage balancing mechanism, which enables the rapid installation of lifting light fixtures on irregular building structures, while ensuring uniform load distribution and improved stability during the lifting process. This invention also provides an installation method and its application for improving the flatness of the foundation of the lifting light fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tooling for installing a lifting light fixture foundation, used to improve the flatness of the lifting light fixture foundation on a rectangular steel structure base, includes metal square steel, a movable section of the light fixture foundation, a steel structure load-bearing connecting section, and a lifting light fixture connecting section;

[0008] The bottom of the metal square steel is adjustablely inserted into the movable section of the lamp holder base, and the top of the metal square steel is fastened to the steel structure bearing body connecting section. The steel structure bearing body connecting section adopts an arc-shaped curved surface to support the tooling components.

[0009] The bottom of the movable section of the lamp holder base is fixed to the lifting lamp holder connecting section by bolt two.

[0010] Preferably, the steel structure load-bearing connecting section is fixed to the top of the metal square steel by welding.

[0011] Preferably, the movable section of the lamp holder base is made of square steel structure larger than the metal square steel. Both sides of the movable section of the lamp holder base are provided with positioning openings with waist-shaped hole structures. Both sides of the metal square steel are provided with positioning holes that match the positioning openings. The positioning holes and the positioning openings are locked together by bolts, thereby fixing the height of the metal square steel on the movable section of the lamp holder base.

[0012] Preferably, the connecting section of the steel structure load-bearing body is replaced according to the different body shape and specifications of the lifting lamp holder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model solves the problem of low efficiency and poor accuracy of traditional lamp holder foundation height adjustment and leveling by using the adjustable insertion structure of metal square steel and the movable section of the lamp holder foundation, and by using the locking method of positioning hole + waist hole.

[0015] (2) This utility model solves the problems of uneven stress at the bottom of the lamp holder, poor fit of the mounting surface, and easy deformation or tilting of the foundation by setting a steel structure bearing connecting section with an arc-shaped curved surface to support the lamp holder.

[0016] (3) This utility model solves the problems of needing to re-customize the installation structure of different specifications of lifting lamp holders, poor versatility, and high construction costs by replacing the connecting section of the steel structure bearing body.
