Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a support beam assembly for cranes. Background Art

[0002] Light gantry crane, also known as mobile gantry crane, is a light and practical lifting equipment. It has a door-shaped structure and can perform cyclic and intermittent movements in various industrial sites. It is widely used in warehouses, docks, workshops and other scenes, especially in places where hanging cranes are inconvenient or uneconomical to use. Light gantry cranes can play their unique advantages.

[0003] The existing light gantry crane has a complex structure and requires professional personnel to operate during disassembly, which is not only time-consuming and labor-intensive, but also prone to operational errors that may cause equipment damage. Therefore, the existing Chinese utility model patent with publication number CN208378217U: a hinged device that facilitates the installation of a gantry crane. The application sets a hinged device between the main beam and the outrigger to flexibly connect the main beam and the outrigger. By lifting the main beam, the outrigger will naturally connect with the main beam, which greatly saves installation time. However, due to the particularity of the use of the gantry crane, the use of the hinged device will increase the instability of the structure. When lifting heavy objects, the hinge point between the main beam and the outrigger may become a weak link in the force and is easily deformed by external forces. In addition, the hinged device may introduce additional degrees of freedom of movement. During the lifting process, if the hinged device is improperly designed or the operation is inaccurate, the relative position between the main beam and the outrigger may change, which will affect the overall stability of the crane and increase safety risks.

[0026] like Figure 2 , Figure 4-Figure 5As shown, both sides of the support column 2 are provided with through grooves 18, and both sides of the through grooves 18 are provided with second card slots 19. A fixed skirt 20 is fixedly installed on the outside of the mounting tube 11, and a transverse slot 21 is provided on the mounting tube 11 below the fixed skirt 20. Both sides of the mounting tube 11 are provided with first telescopic grooves 22, and both sides of the first telescopic grooves 22 are provided with limiting through grooves 23. Both sides of the first limit block 12 are fixedly installed with second limit blocks 24, and the two first limit blocks 12 are provided with second telescopic grooves 25 on the opposite sides thereof, and a card block 26 is inserted and installed in the second telescopic groove 25, and a magnetic block is fixedly installed on one side of the card block 26, and the two first limit blocks 12 are respectively inserted and installed in the corresponding first telescopic grooves 22, and the second limit blocks 2 4 is inserted and installed in the limiting through groove 23, and a compression spring 27 is also inserted and connected with one side of the first limiting block 12 and the first telescopic groove 22. A clamping block 26 is inserted and installed on one side of the first limiting block 12. After the first limiting block 12 is pressed and stored in the first telescopic groove 22, one end of the clamping block 26 is inserted into the second clamping groove 19, so as to telescope and limit the first limiting block 12. The installation tube 11 located above the fixed skirt 20 is inserted and installed in the supporting column 2 by the lower end of the supporting column 2, and the fixed skirt 20 is fixedly connected to the lower end of the supporting column 2 by a plurality of screws. By arranging the installation tube 11 and the first limiting block 12 at the lower end of the supporting column 2, when the supporting column 2 is lifted from the column 1, the supporting column 2 can be limited step by step, which is convenient for the stable lifting of the supporting column 2.

[0027] It should be noted that the utility model is a support beam assembly for a crane. When assembling a gantry crane, it is only necessary to place the two track wheels 4 at the lower ends of the two support beams 3 on the corresponding tracks respectively, and adjust them through the screw supporter 5 so that the lower ends of the screw supporter 5 are supported on the track, so that the support beam 3 and the column 1 are initially placed. Then, the two ends of the track beam of the gantry crane are fixed on the corresponding support columns 2 by bolts respectively, and then, the track beam is lifted by lifting manpower with the help of a lifting rod or an external lifting device. Then, the track beam synchronously drives the two support columns 2 to move up so that when the lower ends of the two support columns 2 are respectively moved up in the corresponding columns 1, the first limit blocks 12 on both sides of the installation tube 11 are clamped with the help of the force of the compression spring 27. In the corresponding first slot 17, the downward movement of the support column 2 is limited, the stability of the lifting of the support column 2 is improved, and the sudden fall of the support column 2 and the track beam due to the sudden failure of the external lifting force is prevented. When the lifting of the support column 2 is completed, its first limit block 12 is clamped in the first slot 17 at the uppermost position on one side of the column 1. Then, the adjusting handle 13 can be rotated, so that the adjusting handle 13 rotates in the screw hole 15 at the lower end of the limit column 9, so that the limit column 9 enters the column 1 and is placed at the lower end of the support column 2, thereby supporting and limiting the support column 2. At the same time, the insert block 16 at the upper end of the limit column 9 is inserted and installed in the slot 21 in the installation tube 11, so as to complete the upward limit of the support column 2, thereby completing the installation of the entire gantry crane;

[0028] When disassembling the gantry crane, it is only necessary to press the two first limit blocks 12 at the lower ends of the two support columns 2 into the corresponding first telescopic grooves 22 respectively, and push the block 26 to one side in the second telescopic groove 25 so that one end of the block 26 is inserted into the corresponding second slot 19, so that the first limit block 12 is no longer placed in the first slot 17, and then, the adjusting handle 13 is rotated in the opposite direction so that the adjusting handle 13 drives the adjusting screw 8 to rotate in the screw hole 15, so that the limit column 9 is gradually moved out of the column 1. When the limit column 9 no longer supports the support column 2, the support column 2 falls to the bottom of the column 1, and then, the track beam between the two support columns 2 can be disassembled, so that the combination of the column 1, the support column 2, and the support beam 3 can be moved out for transportation.
