Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a detachable gantry crane. Background Technology

[0002] Lifting frames are used to lift heavy equipment and move it to a designated area. They are widely used in industries such as industrial production, transportation, and maintenance.

[0003] Most of the gantry cranes currently in use are integrally welded structures. Although this structure is relatively sturdy, its application range is relatively limited. The height of the crane cannot be freely adjusted, and the crossbeams at the top of the crane cannot be freely disassembled and reassembled, resulting in a large space occupation when stored. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable gantry crane, which has the advantages of height adjustment and quick disassembly, thus solving the aforementioned problems.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned purpose of height adjustment and quick disassembly, this utility model provides the following technical solution: a detachable gantry crane, including a horizontal frame, a vertical frame fixedly installed on the top of the horizontal frame, a movable frame inserted inside the vertical frame, fixed components on both sides of the movable frame, an I-beam frame detachably installed on the top of the movable frame, an electric hoist and hook provided at the bottom of the I-beam frame, and insert blocks fixedly installed at both ends of the bottom of the I-beam frame, with insertion holes opened on the surface of the insert blocks.

[0008] Preferably, both sides of the bottom of the horizontal frame are fixedly installed with casters, and a diagonal frame is fixedly installed between the horizontal frame and the vertical frame.

[0009] Preferably, an upper limit frame is fixedly installed on the outer wall of the movable frame, and a lower limit frame is fixedly installed on the inner wall of the vertical frame.

[0010] Preferably, a fixed frame is fixedly installed on the inner wall of the mobile frame, a lead screw sleeve is embedded inside the fixed frame, a lead screw shaft is threaded inside the lead screw sleeve, and the bottom of the lead screw shaft is fixedly installed with the output end of the servo motor.

[0011] Preferably, the fixing component includes a housing, the side of which is fixedly mounted to the movable frame via a mounting plate, a rod is inserted inside the housing, a limit plate is fixedly mounted on the outside of the rod, a spring is fitted on the outside of the rod, and a handle is fixedly mounted on the tail end of the rod.

[0012] Preferably, the insert block is inserted into the top of the movable frame, and the insert rod is inserted into the interior of the socket.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a detachable gantry crane, which has the following advantages:

[0015] 1. This detachable gantry crane uses a servo motor to drive the lead screw shaft to rotate, which in turn causes the lead screw sleeve to move up or down on the lead screw shaft. Consequently, the moving frame moves up or down within the vertical frame, thereby adjusting the horizontal height of the I-beam frame, electric hoist, and hook.

[0016] 2. This detachable gantry crane allows for easy disassembly of the mobile frame by pulling the insert rod outward with the handle, which passively compresses the spring and causes one end of the insert rod to leave the insertion hole, thus freeing the insert block from being restricted. Then, pulling up the I-beam frame allows the insert blocks at both ends of the I-beam frame to leave the top of the mobile frame, thereby achieving the disassembly of the mobile frame and solving the problem of traditional gantry cranes occupying a large amount of space when not in use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 A detachable gantry crane includes a horizontal frame 1, with casters 2 fixedly installed on both sides of the bottom of the horizontal frame 1 to facilitate the movement of the entire gantry crane; a vertical frame 3 is fixedly installed on the top of the horizontal frame 1, and a diagonal frame 4 is fixedly installed between the horizontal frame 1 and the vertical frame 3 to increase the strength of the horizontal frame 1 and the vertical frame 3; a movable frame 5 is inserted inside the vertical frame 3, and the movable frame 5 can move up and down in the vertical frame 3; fixing components 7 are provided on both sides of the movable frame 5 to ensure the fixation of the I-beam frame 8.

[0024] Please see Figure 1-3 The top of the mobile frame 5 is detachably equipped with an I-beam frame 8. The bottom of the I-beam frame 8 is equipped with an electric hoist and a hook 9. Both ends of the bottom of the I-beam frame 8 are fixedly equipped with plug blocks 15. The surface of the plug blocks 15 is provided with plug holes 16. The plug blocks 15 are inserted into the top of the mobile frame 5.

[0025] Please see Figure 1-3 The outer wall of the movable frame 5 is fixedly equipped with an upper limit frame 6 to prevent the movable frame 5 from continuously moving downward; the inner wall of the vertical frame 3 is fixedly equipped with a lower limit frame 10 to prevent the movable frame 5 from continuously moving downward; the inner wall of the movable frame 5 is fixedly equipped with a fixed frame 11, and a lead screw sleeve 12 is embedded inside the fixed frame 11. The lead screw sleeve 12 is threadedly connected to a lead screw shaft 13. The bottom of the lead screw shaft 13 is fixedly installed with the output end of the servo motor 14. The servo motor 14 can drive the lead screw shaft 13 to rotate, and then the lead screw sleeve 12 moves up or down outside the lead screw shaft 13, and then the movable frame 5 moves up or down in the vertical frame 3.

[0026] Please see Figure 3-4 The fixing component 7 includes a housing 70, of which there are two sets of two housings in each set, arranged symmetrically. The side of the housing 70 is fixedly installed to the movable frame 5 via a mounting plate 71. A plug rod 72 is inserted inside the housing 70 and passes through the inside of the insertion hole 16. A limit plate 73 is fixedly installed on the outside of the plug rod 72, a spring 74 is fitted on the outside of the plug rod 72, and a handle 75 is fixedly installed at the tail end of the plug rod 72.

[0027] Working principle: During use, the servo motor 14 drives the lead screw shaft 13 to rotate, and then the lead screw sleeve 12 moves up or down on the lead screw shaft 13. Subsequently, the moving frame 5 moves up or down in the vertical frame 3, thereby adjusting the horizontal height of the I-beam frame 8, the electric hoist and the hook 9.

[0028] By pulling the plug rod 72 outward with the handle 75, the spring 74 is passively compressed, and one end of the plug rod 72 will leave the plug hole 16, so the plug block 15 will not be restricted. Then, the I-beam 8 is pulled up, so that the plug blocks 15 at both ends of the I-beam 8 leave the top of the moving frame 5, thereby realizing the disassembly of the moving frame 5 and solving the problem of large space occupation when the traditional gantry crane is not in use.

[0029] Conversely, insert the plugs 15 at both ends of the I-beam 8 into the top of the vertical frame 3, release the pull of the handle 75, and the spring 74 pushes the plug rod 72 into the plug hole 16 on the surface of the plug 15, thereby locking the plug 15 and preventing the I-beam 8 from shaking and falling.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
