Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to an automatic turning device for a casting sand box. Background Technique

[0002] A fire-fighting sand box is a necessary sand storage tool for fire-fighting. An opening is provided at the upper end of the fire-fighting sand box. When using the fire-fighting sand in the fire-fighting sand box to extinguish a fire, people need to use a fire-fighting shovel or a fire-fighting bucket to take out the fire-fighting sand from the opening of the sand box and cover it on the fire source.

[0003] After patent retrieval, it is found that the publication number: CN112933488A discloses a fire-fighting sand box, which includes a box body. An opening is provided above the box body. A box cover for covering the opening is arranged on the box body. The box body includes a connecting frame and box bodies stably connected to both sides of the connecting frame respectively. A guide cylinder is fixedly arranged on the connecting frame. A sliding shaft is slidably connected in the guide cylinder. One end of the sliding shaft extending out of the guide cylinder is fixedly provided with a roller; a starting mechanism is arranged on the connecting frame. After the starting mechanism is started, it can apply a force to the sliding shaft to make the sliding shaft slide away from the guide cylinder, and the roller abuts against the ground to tightly support the box body. This application has the effect of facilitating the movement of the fire-fighting sand box during a fire.

[0004] The existing sand-taking port of the fire-fighting sand box is located at the top of the sand box. The fire-fighting sand needs to be shoveled out from the top of the sand box. The operation is very inconvenient when shoveling, and the shoveling speed is relatively slow, so rapid fire extinguishing cannot be carried out. To solve the above problems, an automatic turning device for a casting sand box is proposed in this application. Content of the Utility Model

The columns 2 are symmetrically welded to both ends of the upper surface of the base 1. A sand box 3 is rotatably provided between the two groups of columns 2. Rotary seats 6 are rotatably provided at the tops of the inner walls of the columns 2. Rotary shafts 7 are welded to the positions of the two ends of the sand box 3 corresponding to the rotary seats 6. The rotary shafts 7 are respectively rotatably connected to the rotary seats 6;

[0028] One of the rotary shafts 7 penetrates through the rotary seat 6 and the wall of the column 2. A worm gear 8 is fixedly connected to the end of the rotary shaft 7. A worm 9 is drivingly connected to one side of the worm gear 8. A driving handwheel 10 is fixedly connected to the top of the worm 9;

[0029] A first sand discharging port 11 is provided on one side surface of the sand box 3, and a second sand discharging port 12 is provided on the other side surface of the sand box 3.

[0030] It should be noted that the fire sand is filled in the sand box 3. The lock catch 5 can lock the upper cover 4, and the upper cover 4 can close the sand box 3. When the fire sand needs to be taken out, first open the upper cover 4. By rotating the driving hand wheel 10, the driving hand wheel 10 drives the worm 9 to rotate. The worm 9 is in transmission connection with the worm gear 8. The worm gear 8 can drive the sand box 3 to turn under the cooperation of the rotating seat 6 through the rotating shaft 7. When the top opening of the sand box 3 turns and inserts down, the fire sand in the sand box 3 can be quickly discharged. The combination of the worm gear 8 and the worm 9 has a self-locking function, and the sand box 3 can be automatically locked after turning, which is convenient to take out the fire sand from the sand box 3 and improves the safety when taking the sand at the same time.

[0031] In this embodiment, as Figure 1 shown, the top of the sand box 3 is an open structure. The top of the sand box 3 is rotatably connected with an upper cover 4. A lock catch 5 is provided at the connection between the sand box 3 and the upper cover 4, and the lock catch 5 is arranged symmetrically.

[0032] It should be noted that the upper cover 4 can close the top of the sand box 3, and the lock catch 5 can lock the upper cover 4.

[0033] In this embodiment, as Figure 3 and Figure 4 shown, guide rails 13 are provided on the surfaces at both ends of the first sand discharge port 11 and the second sand discharge port 12. The guide rails 13 are welded to the surface of the sand box 3. Covers 14 are slidably arranged in the inner cavities of the guide rails 13. Handles are provided on the surfaces of the covers 14. Locking lead screws 15 are threadedly connected to both ends of the surfaces of the covers 14, and the ends of the locking lead screws 15 abut against the surface of the sand box 3.

[0034] It should be noted that the guide rails 13 can play a guiding role in the lifting of the covers 14.

The worm wheel 8 can drive the sand box 3 to turn over under the cooperation of the rotating seat 6 through the rotating shaft 7. When the top opening of the sand box 3 turns over and inserts down, the fire sand in the sand box 3 can be quickly discharged. The combination of the worm wheel 8 and the worm 9 has a self-locking function, and the sand box 3 can be automatically locked after turning over, which is convenient to take out the fire sand from the sand box 3 and improves the safety when taking out the sand at the same time. When the sand box 3 turns over, the first sand discharge port 11 or the second sand discharge port 12 can be selected according to the storage height of the fire sand in the sand box 3. The cover plate 14 can be lifted by the handle, and the guide rail 13 can play a guiding role in the lifting of the cover plate 14. After the cover plate 14 is opened, it is convenient to take out the fire sand from the first sand discharge port 11 or the second sand discharge port 12, making the sand taking more labor-saving and fast.
