Description

Technical Field

[0001] This utility model relates to the field of traveling wheel disassembly technology, and in particular to a traveling wheel disassembly device for a gantry crane. Background Technology

[0002] A gantry crane is a special type of equipment that uses a portal frame structure to lift and transport heavy objects. It mainly consists of a gantry, outriggers, traveling mechanism, and trolley. It completes horizontal and vertical transportation through cables and pulley blocks. The traveling wheels of the gantry crane are devices used to support the movement of the crane on the track, and mainly undertake the functions of load transfer and equipment operation.

[0003] After high-intensity transportation, the traveling wheels of gantry cranes need to be disassembled, maintained, and lubricated. However, the traveling wheels of gantry cranes are usually fixed with bolts or screws. After long-term movement, the bolts or screws may rust, making it more troublesome to disassemble and maintain the traveling wheels. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for dismantling the traveling wheels of a gantry crane.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gantry crane traveling wheel dismantling device includes a gantry crane body, with connecting seats provided on both sides of the bottom of the gantry crane body, and a traveling wheel mechanism provided at the bottom of the connecting seats. The bottom center of the connecting seat has a sliding groove, and the two sides of the sliding groove have mating grooves. The top of the traveling wheel mechanism is provided with a connecting cover plate, and the top center of the connecting cover plate is provided with a second plug-in block. The upper side of the second plug-in block near the connecting cover plate is provided with a limit block, and the other side of the limit block is provided with a connecting rod. The top of the connecting rod is provided with a threaded rod, and the diameter of the connecting rod is the same as the length of the sliding groove.

[0006] In addition, a preferred structure is that the top of the walking wheel mechanism is provided with an extension block, and the extension block is adapted to the mating grooves opened on both sides of the bottom of the connecting seat.

[0007] Furthermore, in a preferred configuration, when the first insertion block at the top center of the connecting cover is inserted into the slot in the middle of the connecting seat, the length of the connecting rod at the top of the first insertion block is adapted to the length of the slide groove, and the threaded rod at the top of the connecting rod protrudes from the top of the connecting seat.

[0008] Furthermore, in a preferred configuration, a limiting mechanism is provided on the threaded rod, and a threaded sleeve is provided on one side of the limiting mechanism, and a spring washer is provided at the bottom of the threaded sleeve, and the threaded sleeve and the threaded rod are mutually adapted.

[0009] In addition, a preferred structure is that the other end of the limiting mechanism has a docking hole, and the two sides of the docking hole have grooves, and a limiting rod is inserted into the docking hole.

[0010] Furthermore, in a preferred configuration, a limiting hole is provided on the top of the connecting seat on the other side of the slide, and a slot is provided on the vertical surface of the other side of the connecting seat.

[0011] Furthermore, in a preferred configuration, a first insertion block is provided on the vertical surface of the other side of the connecting cover plate, and the first insertion block is adapted to the slot, and the limiting insertion rod is adapted to the limiting hole.

[0012] Furthermore, in a preferred configuration, when the threaded sleeve on the limiting mechanism is fully screwed onto the threaded rod, the mating hole on the limiting mechanism is always on the same axis as the limiting hole.

[0013] The beneficial effects of this utility model are as follows: First, by inserting and removing the limiting rod, the limiting mechanism can be freely deflected. Then, by using a wrench to rotate the threaded sleeve on the limiting mechanism, it can be disengaged from the threaded rod on the traveling wheel mechanism, so that the traveling wheel mechanism can be quickly disassembled from the gantry crane body. Furthermore, by setting the limiting rod, the deflection of the limiting mechanism during the limiting process can be effectively prevented. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A gantry crane traveling wheel dismantling device includes a gantry crane body 1, connecting seats 2 are provided on both sides of the bottom of the gantry crane body 1, and a traveling wheel mechanism 3 is provided at the bottom of the connecting seats 2. A sliding groove 21 is provided in the middle of the bottom of the connecting seat 2, and mating grooves 22 are provided on both sides of the sliding groove 21. A connecting cover plate 4 is provided on the top of the traveling wheel mechanism 3, and a second insertion block 45 is provided in the middle of the top of the connecting cover plate 4. A limit block 42 is provided on the side of the second insertion block 45 near the connecting cover plate 4, and a connecting rod 43 is provided on the other side of the limit block 42. A threaded rod 44 is provided on the top of the connecting rod 43, and the diameter of the connecting rod 43 is the same as the length of the sliding groove 21.

[0018] The top of the walking wheel mechanism 3 is provided with an extension block 31, and the extension block 31 is compatible with the docking grooves 22 opened on both sides of the bottom of the connecting seat 2.

[0019] Meanwhile, when the first insertion block 41 at the top center of the connecting cover plate 4 is inserted into the slot 24 in the middle of the connecting seat 2, the length of the connecting rod 43 at the top of the first insertion block 41 is matched with the length of the slide groove 21, and the threaded rod 44 at the top of the connecting rod 43 protrudes from the top of the connecting seat 2.

[0020] In addition, a limiting mechanism 5 is provided on the threaded rod 44, and a threaded sleeve 51 is provided on one side of the limiting mechanism 5, and a spring washer 52 is provided at the bottom of the threaded sleeve 51, and the threaded sleeve 51 is adapted to the threaded rod 44.

[0021] Furthermore, the other end of the limiting mechanism 5 is provided with a docking hole 53, and grooves 55 are provided on both sides of the docking hole 53, and a limiting rod 54 is inserted into the inside of the docking hole 53.

[0022] Furthermore, a limiting hole 23 is provided on the top of the connecting seat 2 on the other side of the slide 21, and a slot 24 is provided on the vertical surface of the other side of the connecting seat 2.

[0023] Furthermore, a first insertion block 41 is provided on the vertical surface of the other side of the connecting cover plate 4, and the first insertion block 41 is compatible with the slot 24, and the limiting insertion rod 54 is compatible with the limiting hole 23.

[0024] It is worth noting that when the threaded sleeve 51 on the limiting mechanism 5 is fully screwed onto the threaded rod 44, the mating hole 53 on the limiting mechanism 5 is always on the same axis as the limiting hole 23.

[0025] In this embodiment, when the traveling wheel mechanism 3 of the gantry crane body 1 needs to be disassembled and maintained, one side of the gantry crane 1 is first lifted by a high-strength hydraulic device. At this time, the traveling wheel mechanism 3 of the gantry crane body 1 is in a suspended state, and it can then be disassembled.

[0026] Firstly, compared to traditional traveling wheel mechanisms 3, which are mostly fixed to the bottom of the gantry crane body 1 with bolts and screws, these mechanisms are prone to rust and stripping after long-term transportation, making it difficult to disassemble the traveling wheel mechanism 3.

[0027] First, during disassembly, the limiting rod 54 is removed from the mating hole 53 on the limiting mechanism 5 and the limiting hole 23 on the connecting seat 2 according to the grooves 55 on both sides. Then, the threaded sleeve 51 on the limiting mechanism 5 can be rotated with a wrench. At this time, the threaded sleeve 51 will disengage from the threaded rod 44, so that the connecting rod 43 on the traveling wheel mechanism 3 can be removed from the sliding groove 21 on one side of the connecting seat 2. At this time, the traveling wheel mechanism 3 can be completely removed from the connecting seat 2 at the bottom of the gantry crane body 1, so that the traveling wheel mechanism 3 can be disassembled for maintenance.

[0028] After maintenance, simply insert the first plug-in block 41 on the top of the connecting cover plate 4 on both sides of the traveling wheel mechanism 3 into the interior of the slide groove 21, and move the connecting rod 43 at the top along the slide groove 21, thereby driving the entire traveling wheel mechanism 3 to engage with the interior of the connecting seat 2. Then, use the threaded sleeve 51 on the limiting mechanism 5 to fit the threaded rod 44, and use a wrench to rotate the limiting mechanism 5 again, so that the limiting mechanism 5 limits the bottom of the traveling wheel mechanism 3. When it is rotated to the limit position, insert the limiting plug 54 into the docking hole 53 opened on one side of the limiting mechanism 5, so that the limiting mechanism 5 will not deflect due to external force, thereby limiting the traveling wheel mechanism 3 to the gantry crane body 1.

[0029] In this utility model, the limiting mechanism 5 can be freely deflected by first inserting and removing the limiting rod 54. Then, the threaded sleeve 51 on the limiting mechanism 5 is rotated by using a wrench, so that it can be disengaged from the threaded rod 44 on the traveling wheel mechanism 3, so that the traveling wheel mechanism 3 can be quickly disassembled from the gantry crane body 1. Furthermore, the setting of the limiting rod 54 can effectively prevent the limiting mechanism from deflecting when it is limiting.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
