Description

Technical Field

[0001] The invention belongs to the field of construction engineering, and in particular relates to a fertilizer tank protection device. Background Art

[0002] When working on the top plate of the structure next to the fertilizer tank, a protective device must be installed to prevent construction workers from falling into the fertilizer tank and causing safety accidents. Since the other side of the fertilizer tank is the side wall of the foundation pit, it is difficult to fix the protective device between the structure and the side wall of the foundation pit. However, if the protective device such as a guardrail is fixed on the top plate of the structure, it will not only damage the top plate structure of the structure, but also be time-consuming and labor-intensive to install and remove. At present, there are some safety protection devices for fertilizer tanks, but most of them are complex in structure and inconvenient to use. Summary of the invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a fertilizer tank protection device.

[0004] The present invention is achieved through the following technical solutions:

[0005] A fertilizer trough protection device comprises a top plate support frame and a side wall support frame which are perpendicular to each other, and the top plate support frame and the side wall support frame are fixedly connected together by a horizontal fixed shaft; a plurality of one-way bearings are evenly installed on the fixed shaft along the length direction of the fixed shaft, a sleeve is fixed on the outer ring of the one-way bearing, the one-way bearing can rotate unidirectionally around the fixed shaft, a plurality of rectangular grooves are evenly arranged around the outer surface of the sleeve, a protection rod is inserted into the rectangular groove, and the length of the protection rod is greater than the width of the fertilizer trough.

[0006] Preferably, rollers are provided on both the top plate support frame and the side wall support frame.

[0007] Preferably, the top plate support frame and the side wall support frame are both rectangular frames.

[0008] Preferably, a protrusion is provided at the upper end of the protection rod.

[0022] 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.

[0023] The fertilizer tank protection device of this embodiment includes a top plate support frame 1 and a side wall support frame 2. The top plate support frame 1 and the side wall support frame 2 are perpendicular to each other. The top plate support frame 1 is used to be placed on the top plate of the structure on one side of the fertilizer tank, and the side wall support frame 2 is placed on the side wall of the fertilizer tank on one side of the top plate of the structure. The top plate support frame 1 and the side wall support frame 2 can be in various shapes, such as a triangular support frame, a herringbone support frame, a rectangular support frame, etc. The present invention does not limit this. In this embodiment, a rectangular support frame is used, and the top plate support frame 1 and the side wall support frame 2 are both rectangular frames. The top plate support frame 1 and the side wall support frame 2 are fixedly connected together by a horizontal fixed shaft 3. In order to make the entire device more convenient to move, preferably, rollers 8 are provided on the top plate support frame 1 and the side wall support frame 2. A plurality of rollers 8 are provided on the bottom surface of the top plate support frame 1, so that the top plate support frame 1 can slide on the top plate of the structure. Similarly, a plurality of rollers 8 are also provided on the side of the side wall support frame 2 facing the structure, so that the side wall support frame 2 can slide along the side wall of the fertilizer trough (the side wall of the structure).

[0024] Several one-way bearings 4 are evenly installed on the fixed shaft 3 along the length direction of the fixed shaft 3. The outer ring of the one-way bearing 4 is fixed with a sleeve 5. The sleeve 5 can be a steel sleeve. The one-way bearing 4 can rotate unidirectionally around the fixed shaft 3. The sleeve 5 rotates with the one-way bearing 4. The direction of rotation of the one-way bearing 4 is toward the side wall of the foundation pit. Several rectangular grooves 6 are evenly arranged around the outer surface of the sleeve 5. The depth of the rectangular groove 6 is 4-6cm. The protective rod 7 can be inserted into the rectangular groove 6. The size of the protective rod 7 is consistent with the rectangular groove 6, that is, the protective rod 7 can just be inserted into the rectangular groove 6. In this embodiment, six rectangular grooves 6 are evenly arranged around the outer surface of the sleeve 5. The length of the protective rod 7 is greater than the width of the fertilizer groove. Preferably, the length of the protective rod 7 is 20-60cm greater than the width of the fertilizer groove. The appropriate length of the protective rod 7 is selected according to the width of the fertilizer groove. Generally, when it plays a protective role, the inclination angle of the protective rod 7 is preferably between 15-45°. Each one-way bearing 4 corresponds to a sleeve 5, and a sleeve 5 is connected to a protection rod 7, so the uniformly arranged protection rods 7 form a protection effect in the form of a guardrail. In this embodiment, the spacing between the one-way bearings 4 is preferably 10-25 cm, that is, a protection rod 7 is arranged every 10-25 cm. The length of the fixed shaft 3 is the length of the entire device, which is also the length of the protection. The length of the fixed shaft 3 is preferably 2-4 m, that is, the length of each protection device is preferably 2-4 m, which is convenient for moving and storing.

[0025] The end of the protective rod 7 close to the side wall of the foundation pit, i.e., the upper end of the protective rod 7, is preferably provided with a protrusion 9. Preferably, the protrusion 9 is perpendicular to the protective rod 7. The protrusion 9 can be a convex point or a convex block, and it is better to have a pointed bottom. Since the side wall of the foundation pit is an uneven surface, arranging the protrusion 9 at the upper end of the protective rod 7 can increase the friction between the protective rod 7 and the side wall of the foundation pit, thereby further increasing the firmness of the device.

[0026] When the present invention is in use, the device of the present invention is placed on the fertilizer trough within the working range of the construction workers. If the working range of the construction workers is large, multiple devices of the present invention can be placed. When placing, the top plate support frame 1 is placed on the top plate of the structure, the side wall support frame 2 is parallel to the side wall of the fertilizer trough, the fixed shaft 3 is located at the upper edge of the top plate of the structure, the protective rod 7 is inserted into the rectangular groove 6, and then the protective rod 7 is rotated. The protective rod 7, the sleeve 5 and the one-way bearing 4 are rotated toward the side wall of the foundation pit until the upper end of the protective rod 7 is tightly against the side wall of the foundation pit and cannot be rotated anymore. A large friction force is formed between the protective rod 7 and the side wall of the foundation pit. At this time, the roller 8 of the side wall support frame 2 also tightly presses against the side wall of the fertilizer trough. When all the protective rods 7 are pressed against the side wall of the foundation pit, multiple protective rods 7 form a stable protection similar to a guardrail at the fertilizer trough. The more downward force the formed protection has, the tighter the protective rod 7 is stuck to the side wall of the foundation pit. If the construction workers change the construction position, they can gently lift the side wall support frame 2 or any protective rod 7 upwards, let the entire device rotate a little toward the structure, make the protective rod 7 slightly separate from the side wall of the foundation pit, and then slide the entire device to the required position, and then reposition the device. When dismantling after use, they can also gently lift the side wall support frame 2 or any protective rod 7 upwards, first let the protective rod 7 separate from the side wall of the foundation pit, and then drag the entire device to the top plate of the structure, and remove the protective rods 7 one by one.

[0027] 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.
