Technical Field
[0001] The utility model belongs to the technical field of gantry frames, in particular to a gantry frame which is easy to assemble. Background Art
[0002] The gantry crane is a kind of equipment widely used in industries such as industry, logistics and engineering. It is designed to simplify the installation and disassembly process and facilitate transportation and storage. The gantry crane usually adopts a modular structure, and the components can be quickly disassembled and assembled, reducing labor and time costs.
[0003] According to a publicly disclosed, easy-to-assemble gantry (publication number: CN 219990943 U), it includes triangular columns, each with an annular clamping assembly at its upper end, and a telescopic crossbeam assembly between the two annular clamping assemblies. This allows the triangular arrangement of the triangular columns to effectively withstand heavier weights. The gantry requires assembly and disassembly during use. If users cannot assemble and disassemble quickly, it may lead to extended downtime of the production line or project, thereby affecting overall work efficiency and progress. The internal coordination of the aforementioned annular clamping assemblies makes it difficult to effectively enhance the stability of the joints to prevent loosening or shifting during use. This also makes it difficult to reduce the need for professional skills and enable more people to participate in assembly, which needs to be improved. Summary of the Invention
[0004] The purpose of the utility model is to provide a gantry that is easy to assemble. By assembling and splicing the connecting pipe, threaded rod, sleeve, fixed plate and other components inside the structure, the sleeve is tightly sleeved on the connection between the connecting pipe and the threaded rod, which plays a self-locking role and completes the assembly. Through the threaded connection and the pull ring mechanism, the user can complete the assembly and disassembly in a short time. It is suitable for occasions that require frequent movement and adjustment. The simple splicing design reduces the demand for professional skills, enables more people to participate in the assembly, and saves labor costs. The self-locking design of the sleeve and the connecting rod can effectively enhance the stability of the connection and prevent loosening or displacement during use, thereby improving the safety of use and solving the existing problems.

[0007] Furthermore, the sleeve is located between the threaded rod and the connecting tube. Two connecting rods are provided and are symmetrical to each other along the vertical center axis of the circular tube. The sleeve is used to cover the gap between the threaded rod and the connecting tube to strengthen the connection.
[0008] Furthermore, there are two bottom bars, vertical bars and cross bars, which are symmetrical to each other along the vertical center axis of the casing. There are two hooks at the bottom of the cross bar, which is conducive to improving the stability of the gantry.
[0009] Furthermore, an anti-jamming device is provided on the circumferential surface of the threaded rod, and the anti-jamming device includes a thin rod, one end of the thin rod is fixedly connected to the side of the pull ring plate, the side of the thin rod is fixedly connected to an extrusion rod, and the circumferential surface of the threaded rod is fixedly connected to an airbag, the side of the airbag is penetrated by an oil outlet pipe, and a spring is provided inside the airbag, and the threaded rod is lubricated with lubricating oil to prevent the threaded rod from being difficult to rotate when the gantry is dismantled.
[0010] Furthermore, the airbag is located on the displacement track of the extrusion rod, the oil outlet pipe is located at the top of the threaded rod, and the end of the oil outlet pipe away from the airbag is rotatably connected to a cover plate. The design of the cover plate is conducive to covering the oil outlet pipe when oil is not needed to prevent continuous oil discharge.
[0011] Furthermore, a supplementary tube passes through the side of the airbag, and two springs are provided along a linear array on the inner wall of the airbag. The design of the spring is conducive to the automatic reset of the airbag when the airbag is not squeezed.

[0013] The utility model has the following beneficial effects:
[0014] The utility model realizes that the sleeve is tightly sleeved on the connection between the connecting pipe and the threaded rod through the mutual cooperation between the connecting pipe, threaded rod, sleeve, fixing plate and other components inside the assembly splicing structure, which plays a self-locking role and completes the assembly. Through the threaded connection and the pull ring mechanism, the user can complete the assembly and disassembly in a short time, which is suitable for occasions that require frequent movement and adjustment. The simple splicing design reduces the demand for professional skills, enables more people to participate in the assembly, and saves labor costs. The self-locking design of the sleeve and the connecting rod can effectively enhance the stability of the connection and prevent loosening or displacement during use, thereby improving the safety of use.
[0015] The utility model realizes that the thin rod, air bag, spring, extrusion rod, oil outlet pipe and other components inside the anti-stuck device cooperate with each other, so that when the air bag is squeezed, oil will flow out of the oil outlet pipe, lubricating the threaded part of the threaded rod, reducing the jamming during disassembly, and the user can disassemble the gantry more easily. Through the lubrication mechanism of the air bag, the user can quickly and effectively lubricate the threaded rod without disassembling the entire gantry. This design simplifies the maintenance process and saves time and labor costs.

[0027] The sleeve 33 is located between the threaded rod 32 and the connecting tube 31. Two connecting rods 39 are provided and are symmetrical to each other along the vertical center axis of the circular tube 37. The sleeve 33 is used to cover the gap between the threaded rod 32 and the connecting tube 31 to strengthen the connection.
[0028] There are two bottom bars 1, vertical bars 2 and cross bars 313, which are symmetrical to each other along the vertical center axis of the sleeve 33. There are two hooks 7 at the bottom of the cross bar 313, which is beneficial to improving the stability of the gantry.
[0029] An anti-jamming device 4 is provided on the circumferential surface of the threaded rod 32, and the anti-jamming device 4 includes a thin rod 41, one end of the thin rod 41 is fixedly connected to the side of the pull ring plate 312, and the side of the thin rod 41 is fixedly connected to the extrusion rod 44, and the circumferential surface of the threaded rod 32 is fixedly connected to the airbag 42, and the side of the airbag 42 is penetrated by an oil outlet pipe 47, and the inside of the airbag 42 is provided with a spring 43, and the threaded rod 32 is lubricated with lubricating oil to prevent the threaded rod 32 from being difficult to rotate when the gantry is dismantled.

When the gantry has been used to a certain extent and needs to be disassembled but the threaded rod 32 is rusted and stuck, the movement of the above-mentioned middle pull ring plate 312 will drive the thin rod 41 to move, and the movement of the thin rod 41 will drive the extrusion rod 44. The airbag 42 is located on the movement trajectory of the extrusion rod 44. When the extrusion rod 44 moves downward, it will squeeze the airbag 42. Lubricating oil is stored inside the airbag 42. When the airbag 42 is squeezed, oil will flow out of the oil outlet pipe 47 to lubricate the threaded part of the threaded rod 32, reducing the jamming during disassembly. The user can disassemble the gantry more easily. Through the lubrication mechanism of the airbag 42, the user can quickly and effectively lubricate the threaded rod 32 without disassembling the entire gantry. This design simplifies the maintenance process and saves time and labor costs. When oil is not needed, the oil outlet pipe 47 is covered with a cover plate 45 to prevent continuous oil discharge.
