AI Technical Summary
In nonferrous metallurgy ore dressing operations, the operators cannot hang the seat belt high and use it low when working on the steel grating, resulting in the inability to unfold the safety rope, and the seat belt cannot play a buffering role when the personnel fall, which can easily cause injuries to people.
A steel grating seat belt fixture is designed, including a vertically arranged support rod, an adjustment mechanism that can move up and down along the support rod, a hook rack and multiple hooks. Through these components, the suspension height of the seat belt can be flexibly adjusted to ensure that the seat belt can be hung high and used low.
The device is simple in structure, low in production cost, and safe and reliable in structure. It effectively solves the problem that workers cannot use seat belts with high hanging and low when working on steel gratings, and ensures the safety of workers.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety protection equipment, and particularly relates to a steel grating safety belt fixator. Background Art
[0002] In non-ferrous metallurgy ore dressing operations, when operating personnel clean the stirring tank and the foam tank for containing flotation foam, they need to remove part of the steel grating fixed above the tank in the operation area before working. Under the existing conditions, the safety belt can only be hung on the steel grating that has not been removed. However, since the operating personnel cannot hang the safety belt high and use it low during the operation, that is, hang and fix the safety belt at a place higher than the standing position of the person, and the working position of the person is lower than the hanging and fixing position of the safety belt, the inability to hang the safety belt high and use it low will cause the safety rope not to be deployed, and the safety belt cannot play a buffering role after the person falls, which does not meet the requirements of the safety belt hanging specification and is likely to cause personal injury accidents. Content of the Utility Model

[0006] Further, the adjusting mechanism includes a threaded sleeve, an external thread is provided on the outer wall of the support rod, and the threaded sleeve is in threaded cooperation with the support rod.
[0007] Further, a rotating handle is provided at the top end of the threaded sleeve.
[0008] Further, the hook rack is a rectangular plate structure, a perforation is provided at the center of the hook rack, and the support rod passes through the perforation.
[0009] Further, the hook rack is movably connected with the hook.
[0010] Further, a through hole is provided near the edge of the hook rack, the hook passes through the through hole and is arranged on the hook rack, a retaining piece is provided at the top end of the hook, and the hook can move up and down along the through hole.
[0011] Further, the safety belt hanging structure includes a cross bar fixed at the top end of the support rod, and a hanging ring is provided at the outer end of the cross bar.
[0012] Furthermore, the cross bar is horizontally arranged and is disposed in a cross shape.
[0013] The beneficial effects of the present utility model are as follows:
[0014] The device has a simple structure, low manufacturing cost, and a safe and reliable structure, effectively solving the problems that when operating on a steel grating, it is impossible to hang the safety belt high and use it low, and there is no place to hang the safety belt when personnel walk and operate at the edge.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solution of the present utility model will be further described below with reference to the drawings.
[0019] As Figure 1-2 shown, a steel grating safety belt fixer includes a vertically arranged support rod 1; a support base 8 is provided at the lower end of the support rod 1 for supporting the overall device, a safety belt hanging structure is provided at the upper end of the support rod 1, and an adjusting mechanism that can move up and down along the support rod 1 is provided on the support rod 1. The adjusting mechanism includes a threaded sleeve 3, an external thread 2 is provided on the outer wall of the support rod, the threaded sleeve 3 cooperates with the external thread 2 on the support rod 1, a rotating handle 13 is provided on the threaded sleeve 3, and by rotating the rotating handle 13, the threaded sleeve 3 moves up and down on the support rod 1. The bottom end of the adjusting mechanism is provided with a lifting chassis 4, the lifting chassis 4 and the threaded sleeve 3 are of an integral structure, and when the threaded sleeve 3 moves up and down, it drives the lifting chassis 4 to move up and down. A hook holder 5 is lapped on the lifting chassis 4, the hook holder 5 is of a rectangular plate-like structure, a perforation 11 is provided at the center of the hook holder 5, and the support rod 1 passes through the hook holder 5 through the perforation 11. When the lifting chassis 4 moves up and down, it drives the hook holder 5 to move up and down. A plurality of hooks 7 are evenly arranged around the support rod 1 on the hook holder 5 for hooking the grid of the steel grating to generate a pulling force, and the overall device is fixed on the steel grating in cooperation with the support base 8. A through hole 12 is provided near the edge of the hook holder 5, the hook 7 passes through the through hole 12 of the hook holder 5 through the perforation 11, the hook 7 is movably connected to the hook holder 5, and a retaining piece 6 is provided at the upper end of the hook 7.
[0020] The seat belt suspension structure is a crossbar 9 fixedly connected to the upper end of the support rod 1. A suspension ring 10 is fixedly connected to the end of the crossbar 9. The crossbar 9 is horizontally arranged and is arranged in a cross shape.
[0021] When the operator uncovers the steel grating for edge operation when cleaning the mixing tank and the foam tank, first place the support base 8 of the fixing device on the fixed steel grating, then rotate the rotating handle 13 to lower the height of the threaded sleeve 3, the lifting chassis 4 and the hook frame 5, so that the lower end of the hook 7 extends into the grid of the steel grating. Then adjust the position of the hook 7 to hook the grid of the steel grating. Then rotate the rotating handle 13 again to raise the height of the threaded sleeve 3, the lifting chassis 4 and the hook frame 5, so that the hook 7 generates a pulling force on the grid, ensuring that the whole device does not shake. By the combined action of the pressure of the support base 8 on the steel grating and the pulling force generated by the hook 7 on the steel grating, the whole device is firmly fixed on the steel grating.
[0022] After the whole device is installed on the steel grating, hang the safety buckle of the seat belt on the suspension ring 10 at the end of the crossbar 9, and the high-hanging and low-using of the seat belt can be realized; when the operator performs edge operation, the safety wire rope can also be passed through the two suspension rings 10 and fixed, and the operator can hang the safety buckle of the seat belt on the wire rope to realize edge walking operation.
