Description

Technical Field

[0001] This utility model belongs to the field of auxiliary technology for hook replacement, specifically a device for quick replacement of port cargo hooks. Background Technology

[0002] With the continuous development of global trade and the increasing prosperity of the port logistics industry, the efficiency of port cargo loading and unloading has become one of the key factors affecting port operational efficiency and cost control. In the process of loading and unloading cargo at ports, the hook, as a key component of lifting equipment, directly affects the efficiency of the entire loading and unloading operation through its replacement efficiency and convenience.

[0003] For example, Chinese Patent Publication No. CN214496508U discloses a replaceable counterweight shot blasting hook, including a suspension rod, a hook body, and a rotating shaft. The upper end of the suspension rod is connected to the lifting equipment, and the lower end of the suspension rod is provided with a primary connecting lug and a secondary connecting lug, which are symmetrically arranged. By setting a counterweight shot blasting hook composed of a suspension rod, a hook body, and a rotating shaft, and providing a connecting groove, a secondary guide groove, and a positioning groove on the tertiary connecting lug on the hook body, a primary magnet is set on the positioning seat of the secondary connecting lug, a positioning protrusion is set on the rotating shaft, and a secondary magnet is set in the secondary magnet groove on the end face of the rotating shaft, thereby pushing the positioning protrusion into the positioning groove through the repulsive action between the primary and secondary magnets, thus achieving rapid installation of the hook body. However, it is not convenient to stabilize the hook when disassembling the hook body, which makes the hook easy to shake and thus affects the speed of disassembly and replacement. In addition, the hook body is large in size and it is difficult to move it to the accurate and appropriate height when replacing it. Utility Model Content

[0029] It should be noted that a slot is provided on one side of the limiting plate 207 to make the limiting plate 207 fit more closely with the hook 7.

[0030] In this embodiment, preferably, the sliding block 202 is slidably connected in the groove 201, the threaded column 204 passes through and is rotatably connected to one side of the support block 200, and the connecting rod 205 is perpendicular to the connecting plate 206.

[0031] In this embodiment, preferably, a hook 7 is attached to the side of the limiting plate 207 away from the connecting plate 206, and a connecting plate 6 is hinged to one side of the hook 7, while the connecting plate 6 is placed on the limiting plate 207.

[0032] It should be noted that the connecting plate 6 is provided with connecting holes, making it easier to connect the connecting plate 6 to the port cargo hoisting device.

[0033] In this embodiment, preferably, a spacing adjustment component 1 is also included. The spacing adjustment component 1 includes a vehicle plate 100. A spacing adjustment motor 105 is fixedly connected to one side of the vehicle plate 100, and a double lead screw 104 is fixedly connected to the output end of the spacing adjustment motor 105. A moving block 103 is threadedly connected to the double lead screw 104.

[0034] The movable groove 101 is located in the middle of the vehicle plate 100, and a partition block 102 is fixedly connected to the middle of the vehicle plate 100, and the partition block 102 is installed in the middle of the movable groove 101.

[0035] In this embodiment, preferably, the double-threaded lead screw 104 passes through and is rotatably connected to the middle of the vehicle plate 100 and the partition block 102. The double-threaded lead screw 104 is provided with two sets of opposite threads and the partition block 102 serves as the dividing line.

[0036] It should be noted that the shape of its moving groove 101 is square, which makes it more convenient to move and adjust the moving block 103.

[0037] In this embodiment, preferably, the movable block 103 is slidably connected to the movable groove 101, and the side of the movable block 103 away from the movable groove 101 is connected to the support block 200. Both the movable block 103 and the height adjustment component 2 are provided in two sets and are arranged symmetrically.

[0038] In this embodiment, preferably, a caster wheel 3 is fixedly installed on the lower surface of the vehicle platform 100, and four sets of caster wheels 3 are arranged around the lower surface of the vehicle platform 100.

[0039] In this embodiment, preferably, an electric push rod 4 is fixedly connected to one side of the vehicle plate 100, and a support plate 5 is fixedly connected to the output end of the electric push rod 4. At the same time, four sets of support plates 5 and electric push rods 4 are provided and arranged around the vehicle plate 100.

[0040] It should be noted that the support plate 5 is made of rubber, which can effectively adhere to the ground and provide support.

[0041] The working principle of this utility model is as follows: During use, a spacing adjustment motor 105 is installed. The output end of the spacing adjustment motor 105 drives a double-rotating lead screw 104 to rotate along the middle of the vehicle platform 100 and the partition block 102. The rotation of the double-rotating lead screw 104 causes both sets of moving blocks 103 to move inward along the moving groove 101 and the double-rotating lead screw 104. Each moving block 103, along with two sets of support blocks 200, sliding blocks 202, connecting rods 205, connecting plates 206, and limiting plates 207, moves inward to clamp the hook 7 and the connecting disc 6. This makes it easier and more stable to clamp the connecting disc 6 and the hook 7 during disassembly and replacement, preventing them from shaking and affecting the disassembly process. To adjust the unloading speed, a height-adjusting motor 203 is installed. The output end of the height-adjusting motor 203 rotates the threaded column 204. The rotation of the threaded column 204 causes the sliding block 202 to move downward or upward along the slide groove 201 and the threaded column 204 through the limit of the support block 200. The sliding block 202 moves upward or downward along the connecting rod 205, the connecting plate 206, and the limiting plate 207 to adjust the height. The two sets of limiting plates 207 move upward or downward along the hook 7 and the connecting plate 6 to adjust the height. This makes it easier to adjust the height of the connecting plate 6 and the hook 7 when disassembling or replacing them, avoiding the need for a lot of manpower due to the large weight of the connecting plate 6 and the hook 7.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
