Description

Technical Field

[0001] This utility model belongs to the field of lifting gear reinforcement technology, and in particular relates to a lifting gear reinforcement structure for container equipment. Background Technology

[0002] The reinforcement structure of container spreader refers to the strengthened structure formed by adding reinforcing ribs, thickening plates, optimizing welding processes, or using high-strength alloy materials to the main frame, connection parts, and key load-bearing areas of the spreader. This structure is used to improve the overall deformation resistance and load-bearing stability of the spreader. Container spreaders need reinforcement structures because they frequently bear the weight of containers during operation and often face the impact force at the moment of lifting, the swaying torque during lifting, and the adaptation pressure of different container sizes. The reinforcement structure can effectively avoid safety hazards such as breakage and deformation caused by long-term stress or sudden stress, ensuring the safety of lifting operations and the service life of the spreader.

[0003] However, due to the lack of necessary reinforcement during use, existing lifting equipment is prone to breakage when working with the lifting frame. This not only causes safety accidents and significant economic losses, but also poses a considerable safety risk. Utility Model Content

The bottom end of the locking block 324 extends into the mounting groove 322 and is slidably connected to the mounting groove 322. Springs 325 are wound around the outer walls of both slide rods 323.

One end of each spring 335 is fixedly connected to the slide rod assembly 332, and the other end of each spring 335 is fixedly connected to the anti-detachment plate 333.The sliding rod assembly 332 is a structure composed of two sliding rods and a fixed plate. By setting the reinforcing part 3, if reinforcement of the lifting device 1 and the lifting frame 211 is required, the operation is as follows: First, weld the reinforcing frame 311 to the bottom of the lifting device 1. Then, use bolt nut assembly 320 to fix the fall arrestor chain 318 to the lifting lug 319 on the lifting frame 211. Next, insert the fall arrestor chain 318 into the notch 315 on the limiting turntable 314. After insertion, slide it upwards for two... The locking block 324 on the slide rod 323 compresses the spring 325 on the outer wall of the two slide rods 323 when it slides upward, allowing it to accumulate elastic potential energy. The upward movement of the locking block 324 prevents interference with the rotation of the limiting turntable 314. Then, rotating the actuating rod 317 on the limiting turntable 314 counterclockwise causes the limiting turntable 314 to rotate within the reinforcing frame 311, blocking the notch 315 on the limiting turntable 314 and thus preventing interference with the internal rotation. The fall arresting chain 318 is limited. When the limiting turntable 314 rotates to the appropriate position, the locking block 324 can be released. At this time, the locking block 324, under the pushing force of the spring 325 on the outer wall of the two slide rods 323, inserts into the limiting groove 321 on the limiting turntable 314, limiting the limiting turntable 314 and keeping it in this position to prevent the fall arresting chain 318 from sliding out of the notch 315 of the limiting turntable 314. The locking block 324 fixes the limiting turntable 314. Then, by pulling the lever 334 outward, the anti-detachment plate 333 is driven to compress the two springs 335 on the slide bar assembly 332 outward, accumulating elastic potential energy. Then, the pin on the anti-detachment plate 333 is aligned with the anti-detachment groove 331 on the locking block 324. After alignment, the lever 334 can be released, and the springs 335 on the slide bar assembly 332 will push the pin on the anti-detachment plate 333 into the anti-detachment groove 331 on the locking block 324, thus limiting the locking block 324.

[0030] A specific application of this embodiment is as follows: If it is necessary to reinforce the lifting device 1 and the lifting frame 211, the operation steps are as follows: First, the lower anti-fall chain 214 and the upper anti-fall chain 217 are sleeved together. Then, using bolt nut group one 213 and bolt nut group two 216 respectively, the sleeved lower anti-fall chain 214 and the upper anti-fall chain 217 are fixed to the lower lifting lug 212 and the upper lifting lug 215 installed at the main force angle between the lifting device 1 and the lifting frame 211. There are four of these reinforcement structures. The other three need to be installed at the other three main force angle positions of the lifting device and the lifting frame according to the same steps. Through this operation, the lifting device 1 can be reinforced. The reinforcement of the lifting frame 211 effectively prevents its breakage, avoiding accidents and losses. If it is necessary to strengthen the lifting device 1 and the lifting frame 211, the operation is as follows: First, weld the reinforcing frame 311 to the bottom of the lifting device 1. Then, use bolt nut group three 320 to fix the fall arrest chain 318 to the lifting lug 319 on the lifting frame 211. Then, insert the fall arrest chain 318 into the notch two 315 on the limit turntable 314. After insertion, slide the locking block 324 on the two slide rods 323 upward. When the locking block 324 slides upward, it will compress the spring one 325 on the outer wall of the two slide rods 323, allowing it to accumulate elastic potential energy. Moving the locking block 324 upwards avoids interfering with the rotation of the limiting turntable 314. Then, rotating the lever 317 on the limiting turntable 314 counterclockwise causes the limiting turntable 314 to rotate within the reinforcing frame 311, blocking the notch 315 on the limiting turntable 314 and thus limiting the internal fall arrestor chain 318. When the limiting turntable 314 rotates to the appropriate position, the locking block 324 can be released. At this point, under the pushing force of the spring 325 on the outer wall of the two sliding rods 323, the locking block 324 inserts into the limiting groove 321 on the limiting turntable 314, limiting the limiting turntable 314 and allowing it to... Maintaining this position prevents the anti-fall chain 318 from sliding out of the notch 315 of the limiting turntable 314. After the locking block 324 fixes the limiting turntable 314, the pull rod 334 can be pulled outward to drive the anti-detachment plate 333 to compress the two springs 335 on the slide rod assembly 332 outward, so that it accumulates elastic potential energy. Then, align the pin on the anti-detachment plate 333 with the anti-detachment groove 331 on the locking block 324. After alignment, the pull rod 334 can be released, and the springs 335 on the slide rod assembly 332 will push the pin on the anti-detachment plate 333 to insert into the anti-detachment groove 331 on the locking block 324, thereby limiting the locking block 324.
