Abstract
Description
Technical Field
[0001] The utility model relates to the field of safety mother ropes, in particular to a safety mother rope locking device. Background Art
[0002] During the construction of steel structures, safety precautions must be taken for height-based work to prevent workers from falling. Safety ropes are one of the most commonly used safety precautions for height-based work and are widely used in the installation of beam and slab components in multi-story and super-high-rise steel structures.
[0003] In the prior art, the safety rope bracket is fixed to the steel structure beam plate by welding. When in use, the main rope is hung between the two sets of brackets and the sub-rope worn by the construction workers is hung on its surface. Although the welding method has a more stable connection, it is more troublesome to disassemble it later. It needs to be cut from the surface of the steel structure, which easily leads to the bracket being unable to be reused after cutting, increasing the cost of use. In addition, most of the existing brackets fix the main rope to the surface of the lifting ear by knotting, and there is no buffering effect on the lifting ear inside. When the construction worker accidentally falls, the lifting ear is subjected to a large instantaneous impact, and the lifting ear and the rope may break, which cannot be buffered and cannot fully protect the personal safety of the construction workers.
[0004] Therefore, the present invention proposes a safety mother rope locking device to solve the above problems. Utility Model Content
[0005] In order to overcome the defects in the above-mentioned prior art, the utility model provides a safety mother rope locking device. Through the detachable setting of the mounting seat, the bracket body can be used multiple times, and the setting of the pressure block and the fixing bolt can adapt to I-beams of different sizes. The spring and damper can cushion the impact when the worker falls. At the same time, the presence of the connecting frame and the limiting auxiliary block also strengthens the connection strength between the safety mother rope and the limiting main block, making it safer to use.

Specific implementation manners
[0019] To better illustrate and explain the content of the present utility model, the following will be elaborated in conjunction with the accompanying drawings and implementation examples:
[0020] There is Figure 1 - Figure 2 As shown, the present utility model discloses a safety main rope locking device, which includes two pairs of mounting seats 9. A notch 19 is provided on one side of the mounting seat 9 close to the I-beam 1. The notch 19 cooperates with the I-beam 1. An installation mechanism 901 for fixing the mounting seat 9 on the I-beam 1 is provided on the mounting seat 9. A support body 5 is fixedly provided on the mounting seat 9 on one side of the I-beam 1. A fixing mechanism 902 with a buffering effect for fixing the safety main rope 12 is provided between the support bodies 5.
[0021] Furthermore, the fixing mechanism 902 includes an installation space 6 penetrating through the support body 5. A limiting rod 17 is fixedly provided between the upper and lower walls of the installation space 6. A limiting main block 13 is penetrated and slidably connected to the limiting rod 17. An installation through hole 14 for connecting the safety main rope 12 is penetrated through the limiting main block 13.
[0022] Furthermore, limiting auxiliary blocks 11 penetrated by the limiting rod 17 and slidably connected to the limiting rod 17 are further provided on the upper and lower sides of the limiting main block 13. A connecting frame 18 is fixedly connected between the limiting main block 13 and the limiting auxiliary blocks 11.
[0023] Furthermore, a spring 16 penetrated by the limiting rod 17 is fixedly connected between the lower limiting auxiliary block 11 and the bottom wall of the installation space 6. A damper 15 is fixedly connected between the lower limiting auxiliary block 11 and the bottom wall of the installation space 6.
[0024] Furthermore, the installation mechanism 901 includes a chute 3 provided in the bottom wall of the notch 19. A pressing block 10 is slidably provided in the chute 3. The lower end surface of the pressing block 10 is rotatably connected to an extrusion bolt 2 that penetrates and is threadedly connected to the mounting seat 9.
[0025] Furthermore, two through holes 7 are penetrated through the mounting seat 9. A fixing bolt 8 is inserted into the through hole 7. The fixing bolt 8 is threadedly connected to a nut 4 in a matching manner.
[0026] Specifically, when installing the mounting seat 9, the two mounting seats 9 are clamped on the I-beam 1. Then, the fixing bolt 8 is inserted into the through hole 7 to position the mounting seat 9. Then, the extrusion bolt 2 is rotated so that the pressing block 10 abuts against the I-beam 1. At this time, the extrusion bolt 2 is not tightened. Then, the nut 4 is screwed onto the fixing bolt 8 to fix the horizontal position of the mounting seat 9. Finally, the extrusion bolt 2 is tightened to fix the vertical position of the mounting seat 9;
[0027] After connecting the safety main rope 12 to the installation through hole 14, hang the sub-rope on the safety main rope 12. When the worker falls, the safety main rope 12 pulls the limit main block 13 downward. At this time, the damper 15 and the spring 16 are compressed to buffer the limit main block 13;
[0028] Since the safety main rope 12 is pulled and deformed, there is a lateral force of the safety main rope 12 on the limit main block 13, which has a greater impact on the limit main block 13. The presence of the limit auxiliary block 11 and the connecting frame 18 can strengthen the firmness of the limit main block 13 and also enhance the connection stability of the safety main rope 12.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
