TECHNICAL FIELD

[0001] The present application belongs to the technical field of fertilizer groove construction, and particularly relates to a movable safety belt hanging point facility for a fertilizer groove. BACKGROUND

[0002] A fertilizer groove is a part excavated for providing a work surface, and generally refers to a gap between a structure outer wall and a foundation pit side enclosure structure. When workers work in the fertilizer groove or on the structure roof beside the fertilizer groove, they need to hang a safety belt. Since there is no suitable safety belt hanging point around the fertilizer groove, a mobile small crane is generally used as a safety belt hanging point beside the fertilizer groove at present. Since the mobile small crane is light in weight, a counterweight needs to be added to the bottom disc of the mobile small crane to ensure the safety of the workers. However, in this way, the workers cannot conveniently move the safety belt position when working, which brings inconvenience to construction. SUMMARY

[0003] The present application aims to overcome the deficiencies of the background art and provide a movable safety belt hanging point facility for a fertilizer groove.

[0004] The present application is implemented by the following technical solutions:

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] The fat groove movable safety belt hanging point facility of the embodiment comprises mutually perpendicular horizontal frame 1 and vertical frame 2, and the vertical frame 2 is welded at the front end of the horizontal frame 1. The horizontal frame 1 of the embodiment is preferably 50-80 cm in length in the left-right direction and 40-60 cm in length in the front-back direction, and the vertical frame 2 can be the same size as the horizontal frame 1, and the horizontal frame 1 and the vertical frame 2 can both be welded from common rectangular square tubes on the construction site. A plurality of universal wheels 3 are arranged on the lower surface of the horizontal frame 1, and a plurality of universal wheels 3 are also arranged on the rear surface of the vertical frame 2. In the embodiment, two rows of universal wheels 3 are arranged on the horizontal frame 1 and the vertical frame 2, with two universal wheels 3 in each row.

[0023] Two connecting rods 4 are symmetrically fixed on the left and right sides of the horizontal frame 1 upwardly and obliquely, the upper ends of the two connecting rods 4 are fixed on the rear surface of the fixed plate 5, and two oblique support rods 6 are symmetrically fixed between the connecting rod 4 and the vertical frame 2, the upper ends of the two oblique support rods 6 are fixed on the upper part of the connecting rod 4, and the lower ends of the two oblique support rods 6 are fixed on the middle part of the vertical frame 2, and the oblique support rod 6 supports the connecting rod 4. The angle between the connecting rod 4 and the horizontal direction is preferably 20-35°.

[0024] A rotating plate 7 is hingedly connected to the upper end of the fixed plate 5, and in the embodiment, the upper end of the fixed plate 5 is hingedly connected to the upper end of the rotating plate 7 through a hinge 13. A support top rod 11 is vertically upwardly fixed on the rotating plate 7, and the support top rod 11 also uses a rectangular square tube, and the upper end of the support top rod 11 is provided with a universal wheel 3, and a plurality of safety belt hanging rings 12 are arranged on the support top rod 11, and the safety belt hanging rings 12 are used for hanging safety belts. A bolt hole 8 is arranged on the rotating plate 7, the bolt hole 8 is a light hole, a screw rod 9 is downwardly arranged in the bolt hole 8, the lower end of the screw rod 9 is fixed on the fixed plate 5, and the screw rod 9 is fixed with the rotating plate 7 through a nut 10. When the rotating plate 7 rotates around the hinge 13, the angle between the rotating plate 7 and the fixed plate 5 changes, and the angle between the rotating plate 7 and the fixed plate 5 is fixed through the nut 10 and the screw rod 9. In order to make the angle adjustment range larger and more convenient to adjust, the bolt hole 8 of the embodiment is preferably a long hole, so that when the angle between the rotating plate 7 and the fixed plate 5 changes, the screw rod 9 can slide in the long hole to adapt to the change of the angle between the rotating plate 7 and the fixed plate 5. In actual use, the angle between the support top rod 11 and the horizontal direction is generally adjusted to be between 35-45°, which is slightly larger than the angle between the connecting rod 4 and the horizontal direction, and this angle generally meets the use of the facility in the common width fat groove 14.

[0025] The application is used as follows: the horizontal frame 1 is placed on the top plate of the structure 15 beside the fertilizer groove 14, the included angle between the rotating plate 7 and the fixed plate 5 is adjusted according to the width of the fertilizer groove 14, the upper end universal wheel 3 of the upward inclined supporting top rod 11 is pressed against the side wall of the retaining pile 16 beside the fertilizer groove 14, at the same time, the universal wheel 3 of the vertical frame 2 is attached to the vertical side wall of the structure 15, after the adjustment, the screw rod 9 is fixed through the nut 10, then the safety belt is hung on the safety belt hanging ring 12. Since the supporting top rod 11 is pressed against the side wall of the retaining pile 16 and the vertical frame 2 is pressed against the vertical side wall of the structure 15, the universal wheel 3 cannot be displaced in the vertical direction, but can only be displaced in the horizontal direction, which ensures the safety of the worker during operation, at the same time, the worker can make the both ends of the application facility slide along the side wall of the structure 15 and the retaining pile 16 through the universal wheel 3, so as to change the position of the safety belt hanging point. If the worker constructs on the top plate of the structure 15, the worker directly pushes the horizontal frame 1 to move the whole facility on the top plate of the structure 15, if the worker constructs in the fertilizer groove 14, the worker can stand on the scaffold in the fertilizer groove 14 to pull the safety belt, and pull the whole facility to slide through the safety belt. When the application facility is used, the worker directly stands on the top plate of the structure 15 to pull the facility out of the fertilizer groove 14 through the safety belt to the structure 15.

[0026] The application facility can not only conveniently change the position of the safety belt hanging point, but also can change the length of the supporting top rod 11 in the horizontal direction by adjusting the included angle between the rotating plate 7 and the fixed plate 5, so as to adapt to the fertilizer groove 14 with different widths, and the applicability is wider.

[0027] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, but not to limit them; those skilled in the art should understand that the technical solutions recorded in the above examples can be modified, or some technical features can be replaced by equivalents; 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 embodiments of the application.
