Description

Technical Field

[0001] The utility model relates to the technical field of gantry trusses, in particular to a heavy-duty and high-rigidity gantry truss. Background Art

[0002] A gantry is a large metal structure consisting of columns, beams, and diagonal bars. It is commonly used for lifting, loading and unloading, and transportation, and can withstand weights of thousands of tons. Gantry is widely used in manufacturing, construction, docks, mines, shipyards, warehouses, and other fields. Truss structure is the main structural form of gantry. It is composed of many small truss rods.

[0003] The gantry is generally in an external environment. As time goes by, the steel structure is washed by rainwater, and some parts of the structure are corroded, which reduces its structural strength and affects its service life. Based on this, a heavy-duty high-rigidity gantry truss is proposed to add a corresponding structure to the existing gantry truss to improve its structural strength. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a heavy-duty high-rigidity gantry truss, which effectively solves the shortcomings of the prior art.

[0005] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides a heavy-duty and high-rigidity gantry truss, comprising two triangular support frames, the top ends of the two triangular support frames are equipped with horizontally placed trusses, two arc-shaped support assemblies are equipped in the middle of the top surface of the truss, and six mounting seats are installed on the inner walls of both, two connecting rods are installed on both sides of the top surface of the inner wall of the truss, and slings for pulling the middle part of the truss are installed between the two connecting rods and the multiple mounting seats, and reinforcing rods are installed at both ends of the two arc-shaped support assemblies, and the bottom ends of the four reinforcing rods are fixedly connected to the two ends of the inner wall of the truss.

[0006] Preferably, any of the above schemes is that a plurality of stiffening plates are installed on both sides of the bottom surface of the truss, the bottom ends of the plurality of stiffening plates are bent toward each other, and guide rails for the movement of an external overhead crane are installed at the bent positions. By using this scheme, a plurality of stiffening plates are evenly distributed on both sides of the truss, and the bent positions provide installation positions for the guide rails, thereby increasing the contact area between the guide rails and the plurality of stiffening plates, so as to share the lateral load with the truss.

[0007] Preferably, any of the above schemes is that two limit rods are installed in the middle of the top surface of the truss, and the two are placed crosswise. The top ends of the two limit rods are rotatably connected to the middle of the two arc support assemblies respectively. The two limit rods in this scheme facilitate the connection of the two arc support assemblies with the truss. At the same time, the two limit rods are arranged crosswise, thereby preventing the arc support assembly from tilting after being subjected to force, thereby ensuring the stability of the structure. Moreover, both ends of the two limit rods are fixedly connected to the arc support assembly and the truss by fasteners, thereby facilitating assembly and use by users.

[0008] Preferably, any of the above schemes is that the two arc-shaped support assemblies each include a first arc-shaped rod and a second arc-shaped rod, and the two have the same structure, and the adjacent ends are fixedly connected by fasteners. A plurality of fixing rods are arranged between the two arc-shaped support assemblies. By using this scheme, it is convenient to make the first arc-shaped rod and the second arc-shaped rod smaller in size, and they are combined into an arc-shaped support assembly by being connected to each other, which is convenient for processing and manufacturing, as well as subsequent packaging and transportation, and is also convenient for users to assemble and install on site.

When the two connecting rods are installed, the limit blocks facilitate increasing the contact area with the truss, and at the same time are fixedly connected to the truss by fasteners, thereby combining the two support rods and the truss into one, so as to facilitate bearing the lateral load together with the truss.

[0010] The utility model has the following advantages:

[0011] The heavy-duty, high-rigidity gantry truss is provided with a truss, two arc-shaped support assemblies and two connecting rods. The two connecting rods are installed on the top surface of the inner wall of the truss. A plurality of slings are installed between the two arc-shaped support assemblies and the two connecting rods, thereby facilitating the formation of an arched stable structure at the top end of the truss. At the same time, the plurality of slings are used to transfer the gravity of the middle part of the truss to the two arc-shaped support assemblies and convert it into a reverse tension along the length direction of the truss. The two connecting rods and the guide rails improve the tensile performance of the truss and improve the overall structural strength, thereby effectively solving the problems existing in the prior art.

[0019] Multiple stiffening plates 3 are installed on both sides of the bottom surface of the truss 4. The bottom ends of the multiple stiffening plates 3 are bent towards each other, and the bent positions are installed with guide rails 2 for the external crane to travel. As an optional technical solution of the present invention, this makes it easier for multiple stiffening plates 3 to be evenly distributed on both sides of the truss 4. At the same time, the bent positions provide installation positions for the guide rails 2, while increasing the contact area between the guide rails 2 and the multiple stiffening plates 3, so as to share the lateral load with the truss 4.

[0020] Two limiting rods 7 are installed in the middle of the top surface of the truss 4, and the two are placed crosswise. The top ends of the two limiting rods 7 are rotatably connected to the middle of the two arc support components 5 respectively. As an optional technical solution of the present invention, the two limiting rods 7 facilitate the connection of the two arc support components 5 with the truss 4. At the same time, the two limiting rods 7 are arranged crosswise, thereby preventing the arc support components 5 from tilting after being subjected to force, thereby ensuring the stability of the structure. Moreover, both ends of the two limiting rods 7 are fixedly connected to the arc support components 5 and the truss 4 by fasteners, thereby facilitating assembly and use by users.

[0021] Both arc-shaped support assemblies 5 include a first arc-shaped rod 501 and a second arc-shaped rod 502, and the structures of the two are the same. The adjacent ends are fixedly connected by fasteners. A plurality of fixing rods 9 are arranged between the two arc-shaped support assemblies 5. As an optional technical solution of the present invention, this facilitates the first arc-shaped rod 501 and the second arc-shaped rod 502 to be smaller in size. By connecting them to each other, they are combined into an arc-shaped support assembly 5, which is convenient for processing and manufacturing, as well as subsequent packaging and transportation, and is also convenient for users to assemble and install on site.

[0022] The two connecting rods 12 are fixedly connected to the top wall of the truss 4 by fasteners, and the two ends thereof are fixedly connected to the four reinforcing rods 10 respectively.
