Description

Technical Field

[0001] The invention relates to the technical field of handling slings, and in particular to a modular flexible connection cantilever sling and an operating method. Background Art

[0002] At present, handling hoists are widely used, especially cantilever cranes, which are widely used because of their mature technology and low cost. Cantilever cranes are generally column-type and fixed to the installation surface. The column is the center of rotation, and the length of the cantilever is the radius of the hoist. The area where the hoist is used is a fan-shaped area with the column as the center and the cantilever as the radius. The radius of the cantilever crane is generally about 4 meters long depending on the load. The radius of the cantilever crane is fixed, and the coverage area is also fixed, but in actual working conditions, it is often necessary to place the workpiece from an open space to some narrow space. There are obstacles in this space, such as columns, equipment, etc. Traditional cantilever cranes cannot adapt to such space changes, especially in narrow spaces, such as brick well platforms, wind power internals, large ship equipment warehouses, engine warehouses, and other working conditions. In some very compact and narrow spaces, lifting and handling equipment, due to the non-retractable characteristics of the cantilever crane radius, it is very inconvenient to lift equipment in a narrow space. In addition, most traditional cantilever cranes are fixed and non-detachable, which is often not suitable for some temporary maintenance and handling conditions. Based on this, there is an urgent need for a cantilever crane that can arbitrarily bend and change its coverage radius, can stretch and bend like a snake, can arbitrarily change the effective radius of the cantilever crane, can flexibly lift equipment in a small space, and can be temporarily assembled and built like building blocks. Summary of the invention

[0003] The present invention aims to solve the drawbacks of traditional cantilever cranes and invents a modular flexible connection cantilever crane and an operating method which can flexibly change the radius of the traditional cantilever crane, can be temporarily assembled and built on site, and can easily lift and transport in a small area.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A modular flexible connection cantilever hanger, comprising a guide column 1, a guide hole 2, a module body 3, a module cavity 4 and a screw hole 5; wherein: Figure 1-Figure 3 The present invention adopts a modular structure and adopts high-strength aluminum extrusion molding to prepare a cavity-shaped module body 3. The top and bottom of the module body 3 can be sealed according to the requirements of the cylinder; Figure 1-Figure 3, module guide holes 2 are provided on both sides of the module body 3, and a guide column 1 is inserted into the rightmost module guide hole 2; the module bodies 3 are connected in series like a chain by inserting the upper and lower guide columns 1 into the adjacent module guide holes 2, and the high-strength module body 3 is used to replace the traditional cantilever structure, so that the sling can bend and retract freely in the horizontal range, and it can become several or even dozens of joints according to the needs of the site, and is not restricted by the narrow and cramped environment.

[0005] The present invention also has the following additional technical features: As a further specific optimization of the technical solution of the present invention: the cavity of the module body 3 is a module cavity 4, and the cross-section of the module cavity 4 is circular; the module cavity 4 can be processed into a cylinder cavity by grinding for placing and installing the cylinder.

[0006] As a further specific optimization of the technical solution of the present invention: a plurality of screw holes 5 are provided on the outer sides of the top and bottom of the module cavity 4, and the upper end cover and the lower end cover of the cylinder are fixedly mounted on the top and the bottom of the module cavity 4 by bolts and the screw holes 5; As a further specific optimization of the technical solution of the present invention: Figure 4 As shown, the module bodies 3 are connected in series through the guide column 1 and fixed by the anti-drop pin 6 to prevent the adjacent module bodies 3 from being detached, so that all the module bodies 3 form a horizontal flexible cantilever that can be freely bent. One end of the flexible cantilever can hang a pneumatic hoist or an electric hoist, and the maximum travel radius is 7 meters and the minimum radius is 0.5 meters.

[0007] As a further specific optimization of the technical solution of the present invention: Figure 5 The flexible spreader is shown in its fully expanded form. Figure 6 It is a bent form of flexible spreader, which consists of a set of spreaders through columns, modular flexible connection cantilever spreaders and lifting devices.

[0008] Compared with the prior art, the present invention has the following advantages: Advantage 1: The present invention is a revolution of the traditional cantilever crane. The working conditions required by the traditional cantilever crane require a space larger than the radius of the sling. If it is smaller than this space, it cannot be used normally. The invention of this flexible sling completely solves the space requirements of the sling, and the equipment can be lifted and transported normally in a small space. The invention of this flexible cantilever crane can use the sling in only about one-fifth of the space of the traditional cantilever crane. It completely solves the lifting and handling needs in small areas, such as cabins, workshops, fan installation and maintenance, aircraft maintenance and installation, etc., and has huge market prospects.

[0009] Advantage 2: The single module of the present invention is not only a component of the flexible cantilever crane, but each module can also form a large-diameter driving cylinder. Through the mechanism with other accessories, it can realize the function of lifting the workpiece. It is driven by compressed air as the air source, which is particularly suitable for working conditions in explosion-proof areas.

[0010] Advantage 3: The present invention can not only be used in narrow space conditions such as brick well platforms, wind power maintenance, and maintenance of ship engine compartments, but its modular structure can be freely extended or shortened, can be freely and conveniently disassembled, and can ensure the safe connection between modules through the anti-drop pin 6 to ensure that the modules will not fall off.

[0011] Advantage 4: The single module of the present invention is about 10KG-30KG, which can be easily disassembled. On site, it can be matched with different anchor point link accessories, can be temporarily assembled and used, and can be quickly disassembled and stored after use. It can be used in various working conditions, such as containers, factory channels, reliable rigid bases, etc. through different link accessories. BRIEF DESCRIPTION OF THE DRAWINGS
