Description

Technical Field

[0001] This utility model relates to the field of lifting machinery technology, specifically to a hook for lifting machinery. Background Technology

[0002] With the rapid development of my country's large-scale infrastructure construction, energy industry, real estate industry, petrochemical industry, and shipbuilding industry this year, the development of my country's heavy machinery manufacturing industry, such as cranes, has been greatly boosted. Cranes use hooks to lift and hold heavy objects, then transfer them, and finally unload them manually. For example, an existing patent for a hook anti-derailment device for crane machinery, patent number CN201921387919.5, although it achieves hook anti-derailment, in practical applications, this patent relies on the weight of the goods to pull the hook downwards for sealing and anti-derailment. Under this method, if the goods are subjected to external forces that cause them to shift and sway, the goods are very likely to squeeze the vertical plate on the left side, causing it to bend or create gaps, affecting safety. In addition, when hanging and picking up items, the position of the hook is higher than the vertical plate. If the position of the goods is lower, the hanging and picking work cannot be completed smoothly. Therefore, we propose a hook for crane machinery. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] This utility model embodiment provides a hook for lifting machinery, such as... Figure 1-5 As shown, it includes a hook structure 1 and a fixing structure 2, with the fixing structure 2 connected to the inner cavity of the hook structure 1.

[0026] The hook structure 1 includes a hook 101, a fixing ring 102, a support plate 103, a placement groove 104, an anti-slip layer 105, a stop block 106, and a fixing plate 107. A fixing ring 102 is welded to the top of the hook 101. The support plate 103 is movably sleeved within the inner cavity of the fixing ring 102. A placement groove 104 is formed at the bottom of the inner cavity of the hook 101. An anti-slip layer 105 for securing goods is fixedly connected to the bottom of the inner cavity of the placement groove 104. A stop block 106 for blocking goods is rotatably connected to the top left side of the hook 101 via a rotating shaft. A fixing plate 107 is welded to the bottom end of the stop block 106. Figure 1-2 As shown, the outer pull block 106 opens the hook 101, then the hook 101 passes through the lifting point of the goods, and the connecting part of the goods is placed in the placement groove 104. The anti-slip layer 105 is used for anti-slip. After lifting, the orientation of the goods can be adjusted by rotating the fixing ring 102 on the outer ring of the support plate 103. This device, together with the fixing structure 2, realizes the stable anti-detachment of the hook of the lifting equipment and improves the safety of the device.

[0027] Furthermore, the fixing structure 2 includes a slide groove 201, a limiting frame 202, a pull rod 203, a spring 204, and a limiting block 205. The slide groove 201 is formed on the left side of the inner cavity of the hook 101. The limiting frame 202 is slidably connected inside the slide groove 201. The limiting frame 202 is movably sleeved on the outer ring of the fixing plate 107. Pull rods 203 are welded to the front and rear sides of the bottom of the limiting frame 202. Both ends of the pull rods 203 pass through the hook 101 and are slidably connected to the outer surface of the hook 101. A spring 204 for driving the limiting frame 202 to move is fixedly connected to the bottom of the limiting frame 202. The bottom end of the spring 204 is fixedly connected to the bottom of the inner cavity of the slide groove 201. Limiting blocks 205 are welded to the front and rear sides of the right side of the limiting frame 202. The limiting blocks 205 are slidably connected to the middle of the left side of the hook 101. Figure 2-4 As shown, after the goods are secured, the spring 204 pushes the limit frame 202 and the limit block 205 to rise and lock onto the outer ring of the fixing plate 107, preventing the stop block 106 from shifting due to the movement of the goods. When disassembling, simply pull down the pull rod 203 to retract the limit frame 202 into the slide groove 201, and the stop block 106 and the fixing plate 107 can be opened.

[0028] Furthermore, a T-shaped arc groove is provided in the middle of the left side of the hook 101, and the limiting block 205 is also a T-shaped metal arc block, such as... Figure 4 As shown, this is to prevent the limit block 205 from falling off and affecting its use.

[0029] Furthermore, two sets of springs 204 are provided, distributed on the front and rear sides of the bottom of the limit bracket 202, as follows: Figure 4 As shown, this makes the movement of the limit frame 202 more stable.

[0030] Furthermore, the hook 101 has an arc-shaped groove on the outer ring of the pull rod 203, and the pull rod 203 is slidably connected in the arc-shaped groove, such as... Figure 3 As shown, the limit frame 202 is moved by using the pull rod 203.

[0031] Furthermore, the outer ring of the fixing plate 107 is fixedly connected with anti-slip pads, such as... Figure 2 As shown, this improves the stability of the device after it is fixed.

[0032] Furthermore, the anti-slip layer 105 consists of six semi-circular rubber strips, evenly distributed within the placement groove 104. Figure 2 As shown, the anti-slip layer 105 increases the friction between the cargo and the hook 101, making the cargo more stable when lifted.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
