Description

Technical Field

[0001] This utility model relates to the field of lifting clamp technology, specifically a lifting clamp for processing steel structural parts. Background Technology

[0002] During the processing of steel structural components, a crane is needed to lift them. For safety, lifting clamps can be used to hold the steel structural components during the lifting process. According to the patent authorization announcement number: CN219449070U, a lifting clamp for processing steel structural components is disclosed. This utility model discloses a lifting clamp for processing steel structural components, including a mounting beam. The top surface of the mounting beam is connected to a lifting ring that is connected to a crane. Two guide holes are opened on the mounting beam, and clamping assemblies are set in both guide holes. A driving assembly for driving the two clamping assemblies to move is installed on the mounting beam. The clamping assembly includes an L-shaped clamping plate, and an adjustable pressure plate is connected to the clamping plate. The top surface of the I-beam flange abuts against the bottom surface of the pressure plate.

[0003] However, in existing lifting clamps, the clamp frame moves and grips the steel structure via a threaded connection, causing the clamp to sway during lifting. This swaying can loosen the threads, affecting lifting safety. Furthermore, the threaded connection is required for locking the steel structure, but this method is slow and reduces lifting efficiency. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting fixture for processing steel structural components, comprising a lifting plate, a positive and negative screw mounted on the upper end of the lifting plate via bearings, a threaded frame connected to the outer side of the positive and negative screws via threads, a fixture frame fixedly connected to the lower end of the threaded frame, a lower pressure plate slidably connected to the outer side of the fixture frame, a positioning mechanism provided on the fixture frame, a housing fixedly connected to the outer side of the lifting plate, a worm gear fixedly connected to the left outer side of the positive and negative screws, a worm mounted on the upper left side of the lifting plate via bearings, a gear one fixedly connected to the outer side of the worm, a motor fixedly mounted on the upper end of the lifting plate, and a gear two fixedly connected to the outer side of the output end of the motor.

[0006] Preferably, the threaded frame is slidably connected to the lifting plate, and the clamp frame is slidably connected to the lifting plate, so that the threaded frame can drive the clamp frame to move.

[0007] Preferably, the upper end of the lifting plate is equipped with a plurality of evenly distributed mounting brackets, which are fixedly connected to the outer shell and can be used to connect to a crane.

[0008] Preferably, the second gear meshes with the first gear, and the worm gear meshes with the worm, so that the worm gear cannot drive the worm to rotate.

[0009] Preferably, a bracket is fixedly installed on the upper end of the hoisting plate, and the bracket is connected to the connecting shaft of the second gear through a bearing, so that the bracket can support the second gear.

[0010] Preferably, the positioning mechanism includes a connecting cover, a connecting cover is fixedly connected to the outer side of the lower pressure plate, a positioning post is slidably connected inside the connecting cover, a connecting pin is fixedly connected to the outer side of the positioning post, a spring is provided on the outer side of the connecting pin, a positioning groove is opened on the outer side of the clamp frame, the positioning post is slidably connected to the positioning groove, and the positioning post can position the lower pressure plate through the connecting cover.

[0011] Preferably, one end of the spring is fixedly connected to the positioning post, the other end of the spring is fixedly connected to the connecting cover, the connecting pin is slidably connected to the connecting cover, and the spring can automatically reset the positioning post through its elastic force.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adds a worm gear, gear set and motor to the hoisting plate. When it is necessary to clamp the steel structure, the gear set can drive the worm to rotate. During the rotation, the worm can drive the positive and negative screws to rotate through the meshing with the worm gear. After the rotation stops, the self-locking property between the worm and the worm gear can limit the positive and negative screws, thereby effectively preventing the threaded fit of the positive and negative screws from loosening.

[0014] 2. This utility model adds a connecting cover, positioning pin, and positioning groove to the clamping plate. During use, the positioning pin can be driven by the spring force to slide into the positioning groove, thereby completing the positioning of the lower pressure plate and the connecting cover. This allows the lower pressure plate to be positioned quickly. Attached Figure Description
