Abstract
Description
Technical Field
[0001] The utility model relates to the field of slings, in particular to a special sling for super-long cold-bent steel. Background Art
[0002] Cold-formed steel, also known as steel cold-bent profiles or cold-formed profiles, is a steel profile of various cross-sectional shapes and sizes made by bending hot-rolled or cold-rolled strip steel as a blank. At present, a hoist is required for lifting cold-formed steel.
[0003] At present, the structure of the lifting claw of the slings used on the market is fixed, and the length of the mounting beam of the lifting claw cannot be adjusted. When lifting the extra-long cold-bent steel, even if it is hung at the center of the extra-long cold-bent steel, the extra-long cold-bent steel may easily tilt, resulting in an accident where the cold-bent steel and the lifting claw slip. It is not suitable for lifting cold-bent steels of different lengths. At the same time, after the lifting claw of the traditional sling is stuck with the cold-bent steel, when it is lifted to the specified position, the staff needs to manually separate the lifting claw and the cold-bent steel. There is a lack of automatic separation structure, and the staff are very tired. Utility Model Content

[0006] By adopting the above technical scheme, the utility model designs extension seats at both ends of the connecting seat. When the adjusting screw rod is rotated, the distance between the extension seat and the connecting seat can be adjusted, thereby achieving the purpose of adjusting the position of the lifting claw at the bottom of the extension seat, so that it can be suitable for lifting cold-bent steels of different lengths, and prevent the cold-bent steels from tilting and slipping during the lifting process. By installing a hydraulic cylinder on the extension seat, when the hydraulic cylinder drives the connecting block to rise and fall, the first claw seat and the second claw seat can be driven to grasp and open and close under the action of the support rod, thereby achieving the purpose of automatically separating the lifting claw and the cold-bent steel after lifting the cold-bent steel to the specified area, without the need for manual separation by staff, thereby improving work efficiency.
[0007] The utility model is further configured as follows: both ends of the connecting seat are provided with extension grooves, and the extension grooves are slidably connected with the extension rods.
[0008] The adoption of the technical solution facilitates the storage and positioning of the extension rod.
[0009] The utility model is further configured as follows: guide rods are symmetrically bolted on the extension seat, and guide grooves used in conjunction with the guide rods are provided at both ends of the connection seat.
[0010] The above technical solution is adopted to limit the extension seat.
[0011] The utility model is further configured as follows: a fixing block is symmetrically bolted on the top of the connecting seat, and the fixing block is threadedly connected to the adjusting screw rod.
[0012] The above technical solution is adopted to limit the adjusting screw rod.
[0013] The utility model is further configured as follows: the top of the hanging seat is symmetrically bolted with limit blocks, and a hanging rod is bolted between the two limit blocks.
[0014] The above technical solution is adopted to facilitate the hook hanging of the external lifting equipment.
[0015] The utility model is further configured as follows: a clamping seat is bolted to the bottom of the extension seat, and a rotating rod rotatably connected to the first claw seat and the second claw seat is fixedly sleeved inside the clamping seat.
[0016] By adopting the above technical solution, the first claw seat and the second claw seat are rotationally limited.
[0017] The utility model is further configured as follows: one end of the adjusting screw rod away from the extension seat is fixedly sleeved with a rotating disk.
[0018] The adoption of the technical solution makes it convenient for the staff to rotate the adjusting screw rod.
[0019] The utility model is further configured as follows: the output end of the hydraulic cylinder is fixedly sleeved with a connecting block, and the other end of the support rod is hinged to the connecting block through a hinge.
[0020] The above technical solution is adopted to facilitate driving the support rod to move.
[0021] In summary, the utility model has the following beneficial effects:
[0022] 1. The utility model is designed with extension seats at both ends of the connecting seat. When the adjusting screw rod is rotated, the distance between the extension seat and the connecting seat can be adjusted, thereby achieving the purpose of adjusting the position of the lifting claw at the bottom of the extension seat, so that it can be suitable for lifting cold-bent steels of different lengths, and prevent the cold-bent steels from tilting and slipping during the lifting process;
[0023] 2. The utility model installs a hydraulic cylinder on the extension seat. When the hydraulic cylinder drives the connecting block to rise and fall, the first claw seat and the second claw seat can be driven to grasp and open and close under the action of the support rod, so as to achieve the purpose of automatically separating the lifting claw and the cold-bent steel after the cold-bent steel is lifted to the specified area, without the need for manual separation by the staff, thereby improving work efficiency.
