Description

Technical Field

[0001] This utility model relates to the field of building hoisting technology, and in particular to a multifunctional adjustable balance frame. Background Technology

[0002] The overall trend of the precast composite floor slab industry is one of growth and optimization. As the construction industry's requirements for quality and efficiency increase, the market demand for precast composite floor slabs, as an integrated and efficient building material, continues to increase. In particular, the application of precast composite floor slabs is becoming more and more widespread in the field of prefabricated buildings, which has promoted the rapid development of the entire industry. With the development of the industry, the product form of precast composite floor slabs has also undergone targeted upgrades: on the one hand, to adapt to the needs of larger and more diverse building spaces, their modular specifications are gradually expanding towards ultra-wide and ultra-long large sizes; on the other hand, the diversified trend of architectural design is driving the modular shapes of composite floor slabs towards irregular and non-standard shapes, and traditional quadrilateral components can no longer meet the market's design needs for unique architectural spaces. However, there are still some problems to be solved in the current hoisting and balancing frames used for precast composite floor slabs in the industry: The existing balance frame connection seats are mostly fixed, which cannot be flexibly adapted to the hoisting stress points as the components are large in size or irregular in shape. This easily leads to the problem of unbalanced hoisting force, which seriously affects the hoisting stability of large-size and irregularly shaped composite floor slabs. Therefore, it is necessary to design a multi-functional adjustable balance frame. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional adjustable balance frame to solve the defect that the position of the steel wire rope installed on the existing hoisting balance frame is relatively fixed, making it difficult to adjust the force balance according to the shape and size of the product.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-functional adjustable balance frame, including a main beam and a secondary beam, wherein the main beam is provided with a first slide rail along its length direction, and the secondary beam is connected in the first slide rail through a first sliding pair, the main beam and the secondary beam are distributed perpendicularly to each other, and the main beam is symmetrically provided with lifting lugs; The secondary beam is provided with a second slide rail, and a connecting seat is connected to the second slide rail through a second sliding pair.

Mounting holes for fixing fixed pulleys are provided on the secondary beam and the main beam. The fixed pulleys are fixed to the bottom of the secondary beam and the main beam by bolts. The wire rope can be fixed on the wire rope by passing around the fixed pulleys installed on the secondary beam and the main beam.

[0009] As a further technical solution of this utility model, a first locking mechanism is provided on the main beam. The first locking mechanism includes a first locking bolt provided on the side wall of the first roller and a first locking hole opened on the first slide. The first locking bolt passes through the first locking hole and is threaded onto the first roller, thereby locking the position of the secondary beam relative to the main beam.

The main beam 1 is symmetrically provided with lifting lugs 10 for docking hoisting equipment. The secondary beam 2 has a second slide rail 4 with a closed U-shaped cross section. The second slide rail 4 is connected to a connecting seat 7 through a second sliding pair 6. The second sliding pair 6 is used to adjust the position of the connecting seat 7 on the secondary beam 2. The connecting seat 7 is used to fix the wire rope for hoisting. The secondary beam 2 and the main beam 1 are provided with mounting holes for fixing pulleys. The pulleys are fixed to the bottom of the secondary beam 2 and the main beam 1 by bolts. The wire rope can pass around the fixed pulleys installed on the secondary beam 2 and the main beam 1 and be fixed on the wire rope.

[0018] Specifically, in use, firstly, adjust the relative position of the secondary beam 2 on the main beam 1 according to the size of the product being hoisted. After adjustment, the first locking screw passes through the first locking hole and is threaded onto the first roller 51, thus locking the position of the secondary beam 2 relative to the main beam 1. Then, adjust the position of the connecting seat 7 on the secondary beam 2. After adjustment, the second locking bolt passes through the second locking hole and is threaded onto the second roller 61, thus locking the position of the connecting seat 7 relative to the secondary beam 2. After the position is locked, install fixed pulleys on the secondary beam 2 and the main beam 1. One end of the wire rope is fixed to the connecting seat 7, and the other end passes around the fixed pulley and the movable pulley of the product being hoisted and connects to the multi-claw lifting chain. During hoisting, the connecting seat 7 can be used as a fixed point for one end of the wire rope to balance the force point of the hoisting. This can meet the needs of prefabricated components of different sizes and shapes, improving the practicality of the product.
