Description

Technical Field

[0001] This utility model relates to the field of liquid tank transfer technology, and in particular to a liquid tank transfer mechanism for a small-capacity gantry crane. Background Technology

[0002] With the development of gas carriers, the volume of liquid tanks is getting larger and larger, and the manufacturing sections are also getting larger. The core component of a gas carrier is the liquid tank, which is used to safely store and transport cryogenic liquefied gases. The transfer of these sections usually requires the use of large gantry cranes. A gantry crane, also known as a portal crane, is a large lifting device that spans across rails or the ground. It consists of a main beam, outriggers, a lifting trolley, a traveling mechanism, etc.

[0003] In the existing technology, due to the limitations of the equipment lifting weight and the center of gravity position of the liquid tank section, although the weight of the liquid tank section is within the allowable range of the crane, it requires two trolleys to lift it. However, because the center of gravity position cannot be used to arrange lifting points for lifting with two trolleys, the liquid tank section cannot be transferred. Utility Model Content

[0004] The purpose of this utility model is to provide a liquid tank transfer mechanism for a small-capacity gantry crane, so as to solve the problem mentioned in the background art that the liquid tank cannot be transferred in sections because the center of gravity cannot be arranged to place the lifting point and two trolleys are used for lifting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a transfer assembly comprising a lifting trolley, a first connecting steel rope, lifting lugs, a lifting bar, a second connecting steel rope, and a connecting hook. A lifting and arranging mechanism is provided at the bottom of the transfer assembly, comprising a connecting frame, an adjusting frame, a threaded groove, a fastening threaded rod, a stabilizing block, a lifting frame, an adjusting groove, a sliding groove, and a locking groove. A stabilizing assembly is provided at the bottom of the lifting and arranging mechanism, comprising a connecting belt, a main lifting arm, and a support belt. A liquid tank segment body is provided at the top of the stabilizing assembly.

[0006] In a preferred embodiment, the lifting trolley is provided in two sets, and the bottom pulleys on both sides of the lifting trolley are movably connected to the top outer wall of the first connecting steel rope, and the bottom outer wall of the first connecting steel rope is movably connected to the inner wall of the lifting lug.

[0007] In a preferred embodiment, the inner wall of the lifting lug is rotatably connected to the outer walls of both ends of the lifting bar, and the bottom of the lifting lug is movably connected to the top outer wall of the second connecting steel rope, and the bottom outer wall of the second connecting steel rope is movably connected to the top of the connecting hook.

[0008] In a preferred embodiment, the bottom of the connecting hook is movably connected to the outer wall of the connecting frame, and one side of the connecting frame is fixedly connected to one side of the adjusting frame. The other side of the adjusting frame has a threaded groove, and the inner wall of the threaded groove is threadedly connected to the outer wall of the fastening threaded rod.

[0009] In a preferred embodiment, the top end of the fastening threaded rod is fixedly connected to the bottom end of the stabilizing block, and the top of the stabilizing block is provided with a pentagonal groove, and the outer wall of the adjusting frame is movably connected to the inner wall of the hanging frame.

[0010] In a preferred embodiment, the hanging frame has an adjustment groove inside, a sliding groove at the top of the adjustment groove, and multiple sets of slots on the inner wall of the sliding groove. The inner wall of the connecting hook is movably connected to the outer wall of the connecting frame.

[0011] In a preferred embodiment, the inner wall of the sliding groove is movably connected to the outer wall of the fastening threaded rod, and the outer wall of the stabilizing block is movably connected to the inner wall of the slot.

[0012] In a preferred embodiment, the bottom of the connecting frame is movably connected to the top of the connecting belt, and the bottom of the connecting belt is movably connected to the bottom of the main crane, while the bottom of the main crane is movably connected to the top of the support belt.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model stabilizes the lifting lugs by means of a lifting bar. Since the connecting hooks are connected by a connecting frame and a lifting frame, the center of gravity of the liquid tank section is kept stable when the liquid tank section is lifted. Through the connection of the connecting frame and the lifting frame, the transfer of the liquid tank section is not limited by the lifting weight of the crane or the position of the center of gravity of the liquid tank section, thus ensuring the safety of the transfer of the liquid tank section.

[0015] 2. In this utility model, the threaded groove drives the stabilizing block to move upward, so that the stabilizing block is away from the inside of the slot. The connecting frame is moved, and at the same time, the adjusting frame is moved inside the adjusting groove. Meanwhile, the fastening threaded rod moves inside the sliding groove. After the position of the connecting frame is adjusted, the stabilizing block is rotated so that the stabilizing block enters the inside of the slot, thereby stabilizing the length adjustment of the connecting frame and the lifting frame. This facilitates the lifting of different sections of the liquid tank body while ensuring the stability of the center of gravity. Attached Figure Description

[0028] Specifically, the setting of the lifting bar 104 ensures the stability between the two sets of lifting trolleys 101.

[0029] In one embodiment, the bottom of the connecting hook 106 is movably connected to the outer wall of the connecting frame 201, and one side of the connecting frame 201 is fixedly connected to one side of the adjusting frame 202. The other side of the adjusting frame 202 has a threaded groove 203 inside, and the inner wall of the threaded groove 203 is threadedly connected to the outer wall of the fastening threaded rod 204.

[0030] Specifically: the threaded groove 203 drives the stabilizing block 205 to move upward, so that the stabilizing block 205 moves away from the inside of the slot 209.

[0031] In one embodiment, the top end of the fastening threaded rod 204 is fixedly connected to the bottom end of the stabilizing block 205, and the top of the stabilizing block 205 is provided with a pentagonal groove, and the outer wall of the adjusting frame 202 is movably connected to the inner wall of the hanging frame 206.

[0032] Specifically: As the connecting frame 201 moves, the fastening threaded rod 204 moves inside the sliding groove 208. The sliding groove 208 facilitates the movement of the fastening threaded rod 204. The lifting frame 206 ensures that the transfer of the liquid tank section body 4 is not limited by the crane's lifting weight or the center of gravity of the liquid tank section body 4, thus ensuring the safety of the transfer of the liquid tank section body 4.

[0033] In one embodiment, the hanging frame 206 has an adjustment groove 207 inside, and a sliding groove 208 is provided at the top of the adjustment groove 207.

[0039] Working principle: The support belt 303 is fitted onto the bottom of the liquid tank section body 4. The liquid tank section body 4 is lifted by the movement and lifting of the lifting trolley 101. During the lifting process, the lifting lugs 103 are stabilized by the lifting bar 104. Since the connecting hooks 106 are connected by the connecting frame 201 and the lifting frame 206, the center of gravity of the liquid tank section body 4 is kept stable when it is lifted. The stabilizing block 205 is rotated using a tool, which in turn drives the fastening threaded rod 204 to rotate. At the same time, the fastening threaded rod 204 rotates through the thread groove. 203 drives the stabilizing block 205 to move upward, so that the stabilizing block 205 is away from the inside of the slot 209, moves the connecting frame 201, and at the same time drives the adjusting frame 202 to move inside the adjusting groove 207.
