Description

Technical Field

The utility model relates to the technical field of building construction equipment, in particular to a large-span and super-heavy steel beam supporting and moving device.

Background Art

In recent years, the application of long-span design in building structures has become more and more widespread. In the construction process of building structures, steel structures are often used as the main load-bearing components, such as light wells and roof steel structures. Due to the large span, the size of steel components such as steel beams is large, and the weight is heavy, the movement and transportation of steel components on the construction site are difficult.

Chinese utility model patent CN212861517U discloses a steel component transport device for construction sites, including a load-bearing frame structure, a load-bearing plate and a plurality of roller assemblies, wherein the load-bearing frame structure includes a load-bearing frame and a support assembly disposed in a frame opening of the load-bearing frame, the load-bearing plate is disposed at the upper end of the load-bearing frame structure, and at least partially disposed on the load-bearing frame, the steel component to be transported is placed on the upper end surface of the load-bearing plate, and a plurality of roller assemblies are arranged at the lower end of the support assembly. The transport device has the following shortcomings:

1. When moving steel structures by rollers, due to the complex construction site environment, uneven ground, and heavy weight of steel components, the rollers are easily damaged by uneven force or impact during transportation, affecting transportation efficiency and safety.

2. Since the steel components of the large-span structure are relatively long, the size of the load-bearing frame structure also needs to be correspondingly large, the volume and mass of the transportation device are large, the cost is high, and the turnover is inconvenient.

3. Since the load-bearing frame structure is a planar structure, it is not conducive to the lateral protection of steel components. Once it is subjected to lateral vibration during transportation, it is easy to cause the steel components to shift or even fall, posing a great safety hazard.

Therefore, it is necessary to provide a large-span, super-heavy steel beam supporting mobile device, which can solve the problems in the prior art that the rollers are easily damaged, the transport device is large in size and mass, and the steel components are prone to lateral falling.

Please refer to Figure 1. Each group of lateral protection frames 2 includes a vertical protection rod 201 and an oblique support rod 202. The vertical protection rod 201 is vertically arranged on the bottom frame 1, and a U-shaped limiting space is formed between the vertical protection rod 201 of a pair of lateral protection frames 2 and the bottom frame 1; the oblique support rod 202 is obliquely arranged between the vertical protection rod 201 and the bottom frame 1 and is located on the outside of the U-shaped limiting space.

A pair of sliding components 3 are symmetrically arranged, and the force is evenly and stably applied, so that they can provide stable support for the ends of the large-span and super-heavy steel beams, and have high balance and safety when moving the large-span and super-heavy steel beams.

Please refer to Figures 1 and 2. Each group of sliding components 3 includes a pulley frame 301 and a pulley 302; the pulley frame 301 is an inverted L-shaped structure, one end of the pulley frame 301 is fixedly connected to the inner side of the vertical protection rod 201 through a mounting plate 303, and the other end of the pulley frame 301 is fixedly connected to the bottom frame 1; the pulley 302 is rotatably mounted on the horizontal section of the pulley frame 301 through a wheel bearing.

The axle of the roller 302 can be used as the horizontal section of the pulley frame 301, and the triangular bracket can be used as the vertical section of the pulley frame 301, which is used to install and support the pulley 302. The pulley frame 301 can be made of steel material and welded to the bottom frame 1 and the vertical protection rod 201. It has strong integrity and bearing capacity and can support large-span and super-heavy steel beams.

Please refer to Figure 3. A tenon structure 101 is provided on the bottom surface of the bottom frame 1, and a mortise structure 401 is provided on the top of the floor tank 4. The mortise structure 401 is matched with the tenon structure 101 and is reinforced by bolts, so that the floor tank 4 is installed on the bottom surface of the bottom frame 1.

The ground tank 4 can operate safely in the complex environment of the construction site, and the movement stability of the entire mobile component is improved, thereby safely, stably and efficiently transporting large-span and extra-heavy steel beams.

Please refer to Figures 1 to 3, the method of using the utility model is:

Two moving components are respectively arranged under the two ends of the large-span super-heavy steel beam, and the number of moving components can also be increased according to the length of the large-span super-heavy steel beam, so that the large-span super-heavy steel beam is placed in the U-shaped limiting space of the two moving components, and the moving components at both ends provide stable support for the large-span super-heavy steel beam. Through the arrangement of the ground tank 4, the four ground tanks 4 at the bottom of the two moving components operate synchronously, so that the large-span super-heavy steel beam is driven to move in a specified direction through the two moving components, thereby realizing the transportation of the large-span super-heavy steel beam.

The ground tank 4 increases the contact area with the ground through the tank chain, and has higher running stability and safety than the roller of the prior art. The ground tank 4 is a commonly used transport auxiliary component, and the structure and working principle of the ground tank 4 are not described here.

During the movement, both ends of the large-span and heavy-duty steel beam are in contact with the buffer ring 304, and the self-weight of the large-span and heavy-duty steel beam is used to make the large-span and heavy-duty steel beam and the pulley 302 have a high relative stability, so that the large-span and heavy-duty steel beam moves synchronously with the two moving components. During the movement, a low speed and a uniform speed are ensured to reduce the influence of acceleration and deceleration on the stable setting of the large-span and heavy-duty steel beam.

After moving into position, an axial force is applied to the large-span and extra-heavy steel beam through lifting equipment or manpower. Since the pulley 302 can rotate through the wheel bearing, the large-span and extra-heavy steel beam can be translated out of the U-shaped limit space under the action of the axial force, thereby unloading the large-span and extra-heavy steel beam from the moving component, and operations such as hoisting of the large-span and extra-heavy steel beam can be carried out, which saves effort.

The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
