Technical Field

[0001] The utility model belongs to the field of building construction safety, and in particular relates to a fertilizer trough safety protection device. Background Art

[0002] The fertilizer trough refers to the part that is excavated to provide a working surface. Generally, it refers to the space between the outer wall of the structure foundation and the supporting edge of the foundation pit after earthwork excavation. When workers are working on the top plate of the structure next to the fertilizer trough, safety protection devices need to be installed to prevent workers from falling into the fertilizer trough. At present, guardrails or protective nets are generally used for protection. The installation and removal of guardrails or protective nets are relatively complicated and require damage to the structure. Summary of the invention

[0006] Preferably, the support plate is fixed to the upper surface of the foundation pit by anchor bolts.

[0007] Preferably, the support plate has a width of 1-2 m.

[0008] Preferably, the protective frame is provided with handles at both left and right ends, and the handles are parallel to the horizontal protective rod.

[0009] Preferably, the insert block is a rectangular block or a trapezoidal block that is wider at the top and narrower at the bottom.

[0010] Preferably, the protective frame is 2-5m in length.

[0011] The fertilizer trough safety protection device of the present invention only requires the insert block of the protection frame to be aligned with the rectangular hole and inserted and laid flat. The disassembly and assembly are faster than traditional guardrails or protection nets, and there is no need to punch holes or damage the top plate of the structure.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] The fertilizer tank safety protection device of this embodiment includes a support plate 2, which is fixed to the ground on the upper surface of the foundation pit 1 by anchor bolts 13. The support plate 2 preferably has a width of 1-2m. A plurality of vertical rods 3 are evenly fixed downward on the edge of the support plate 2 close to the fertilizer tank 7. The vertical rods 3 are arranged along the length direction of the support plate 2 and are evenly spaced. Two parallel cross rods 4 are integrally connected to the bottom surface of the vertical rods 3. The two cross rods 4 connect the vertical rods 3 together. There is a gap between the two cross rods 4, so that a plurality of rectangular holes 5 are enclosed between the vertical rods 3 and the cross rods 4, and these rectangular holes 5 are evenly spaced.

[0021] The present invention also includes a protective frame 6, which is used to be placed at the position of the fertilizer tank 7 to protect the safety of workers. The length of the protective frame 6 is preferably 2-5m, and the width of the protective frame 6 is greater than the width of the fertilizer tank 7, and the width of the protective frame 6 is about 0.3-1m greater than the width of the fertilizer tank 7. The protective frame 6 includes a plurality of evenly spaced horizontal protective rods 8, which are perpendicular to the vertical rods 3 and the horizontal rods 4, and the ends of the plurality of horizontal protective rods 8 close to the structure 9 are fixed together with the horizontal connecting plate 10. The horizontal protective rod 8 corresponds to the rectangular hole 5, and the end of the horizontal protective rod 8 close to the foundation pit 1 is vertically downwardly provided with an insert block 11, which matches the rectangular hole 5, and the insert block 11 can be inserted into the rectangular hole 5. The insert block 11 can be a rectangular block, which is more convenient for inserting the insert block 11 into the rectangular hole 5. The insert block 11 can also be a trapezoidal block with a wide top and a narrow bottom. The insert block 11 used in this embodiment is a rectangular block, and the size of the rectangular block can be slightly smaller than the rectangular hole 5, so that it is more convenient to insert into the rectangular hole 5. The height of the plug block 11 is greater than the height of the rectangular hole 5. The height here refers to the dimension in the vertical direction, that is, after the plug block 11 is inserted into the rectangular hole 5, a part of it can be exposed below the rectangular hole 5, which can better ensure the stability of the device. In order to facilitate the placement and removal of the protective frame 6, handles 12 are provided on both ends of the protective frame 6. The handles 12 are fixed on the horizontal connecting plate 10 and the horizontal protective rod 8, and the handles 12 are parallel to the horizontal protective rod 8. The upper surface of the cross bar 4 is flush with the upper surface of the top plate of the structure 9, so that the protective frame 6 can be laid flat.

[0022] When in use, the support plate 2 is fixed on the upper surface of the foundation pit 1, and the vertical rod 3 connected to the support plate 2 is close to the side wall of the foundation pit 1, with a distance of 3-5 cm from the side wall of the foundation pit 1. Then the worker lifts the end of the plug block 11 of the protection frame 6 on the top plate of the structure 9, aligns it with the rectangular hole 5 and puts the protection frame 6 down, inserts the plug block 11 into the rectangular hole 5, and places the horizontal connecting plate 10 of the protection frame 6 on the top plate of the structure 9. At this time, the protection frame 6 is in a horizontal state, forming a guardrail above the fertilizer tank 7. According to the scope of workers' work activities, the number of protection frames 6 to be placed is selected as needed to ensure the safety of workers during construction.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
