An anti-skid pad 10 is fixedly connected to the side of the second wedge block 9 corresponding to the steel structure column 1. The anti-skid pad 10 fits the steel structure column 1. A spring 11 is evenly fixedly connected to the bottom surface of the second wedge block 9, and the spring 11 is fixedly connected to the top surface of the support plate 8. The first wedge block 7 is a right triangle, and the second wedge block 9 is a right trapezoid. The inclined surface of the first wedge block 7 fits and slides with the inclined surface of the second wedge block 9.
[0022] The device is hooked on the steel structure column 1 through the clamping seat 4, and cooperates with the hanging hole 6 to provide a safety rope for hanging. When in use, the spring 11 provides an upward elastic force. At this time, the second wedge block 9 moves upward, and with the cooperation of the first wedge block 7, the second wedge block 9 is squeezed close to the steel structure column 1, thereby forming a clamping limit through the anti-slip pad 10 and the front inner wall of the clamping seat 4. When falling, the anti-slip pad 10 is subjected to an upward friction force, so that the second wedge block 9 is further pushed upward. At this time, with the cooperation of the first wedge block 7, the second wedge block 9 further squeezes the anti-slip pad 10 and the steel structure column 1, thereby hindering the downward fall, effectively playing an anti-fall effect.
[0023] The inner wall of the side of the clamping seat 4 is fixedly connected to the steel structure column 1 with a plane bearing 12. Through the arrangement of the plane bearing 12, the support seat 4 can roll smoothly on the side of the eye column 1, effectively reducing the side friction and jamming.

[0031] The working principle of the utility model is:
[0032] When in use, the back plate 3 is fitted with the steel structure column 1, and the connecting beam 15 is placed corresponding to the threaded rod 16, so that the threaded rod 16 passes through the connecting beam 15, and is locked by the nut 17, so that the clamping seat 4 is clamped on both sides of the steel structure column 1. During the clamping process, the second wedge block 9 is pressed down to control the gap of the clamping seat 4 of the anti-skid pad 10, so that the edge of the steel structure column 1 is convenient to be inserted. After insertion, the second wedge block 9 is released, and the second wedge block 9 is bounced up under the action of the spring 11. Through the inclined surface cooperation of the first wedge block 7, the second wedge block 9 drives the anti-skid pad 10 to move closer to the steel structure column 1, thereby forming an extrusion clamping effect. At this time, the safety rope can be installed corresponding to the hanging hole 6 to play an anti-fall protection effect. During the process, the equipment is directly lifted by the handle 19. At this time, the anti-skid pad 10 is subjected to downward friction. , so that the second wedge block 9 remains in a downward state and the clamping state is released. At this time, the equipment can slide upward along the steel structure column 1, and the spring 11 provides an upward elastic force. At this time, the second wedge block 9 moves upward, and with the cooperation of the first wedge block 7, the second wedge block 9 is squeezed and close to the steel structure column 1, thereby forming a clamping limit with the anti-slip pad 10 and the front inner wall of the clamping seat 4. When falling, the anti-slip pad 10 is subjected to an upward friction force, so that the second wedge block 9 is further pushed upward. At this time, with the cooperation of the first wedge block 7, the second wedge block 9 further squeezes the anti-slip pad 10 and brings it close to the steel structure column 1, thereby hindering the downward fall and effectively preventing it from falling. When removing it, the pull rope 14 can be directly pulled to pull the second wedge block 9 downward, thereby releasing the clamping, so that the equipment can be towed and dropped as a whole.
