Description

Technical Field

[0001] This utility model relates to the field of garbage truck unloading and anti-falling devices, specifically to a safety device for preventing garbage trucks from tipping over and falling into the storage area on an unloading platform. Background Technology

[0002] Waste-to-energy plants incinerate municipal solid waste, which is typically transported by municipal garbage trucks to the incineration plant's unloading hall and dumped into the waste storage pit. When garbage trucks unload into the storage pit through the unloading gate on the unloading platform, the rear of the truck must be directly facing the unloading gate, and the truck body must be repeatedly raised to the maximum angle towards the gate to ensure that all the garbage is unloaded into the storage pit. Some garbage trucks are prone to rear-end imbalance during unloading, which can easily lead to accidents where the garbage truck overturns into the storage pit, posing a significant threat to the personal safety of staff and the economic efficiency of operations.

[0003] In existing technologies, garbage trucks are generally connected to ground anchors using steel wire ropes. However, due to the varying sizes of garbage trucks, even with steel wire ropes of different lengths, the requirements are still not met. When the ground anchor steel wire ropes are attached to most vehicles, they are slack and cannot provide effective protection in the initial stage when the truck's front end lifts up, which can easily cause vehicle damage or personal injury. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a garbage dump anti-fall device.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See Figures 1 to 4As shown, the structure of this utility model is as follows: a safety device for preventing garbage trucks from tipping over and falling into the storage area on an unloading platform, including a slide rail 1; a rack 2, fixedly mounted on the slide rail 1; an anchor 3, slidably mounted on the slide rail 1; a gear 4, rotatably mounted on the anchor 3 and meshing with the rack 2; a locking assembly 5, located on one side of the gear 4, for locking the gear 4; and a lever assembly 6, located on the anchor 3 and connected to the locking assembly 5. The anchor 3 includes a top plate 301, with a first roller 303 rotatably mounted at the bottom of the top plate 301 that abuts against the upper surface of the slide rail 1. Side plates 302 are provided on both sides of the top plate 301, the cross-section of the side plates 302 being L-shaped, and a lever 303 rotatably mounted on the side plates 302 that abuts against the lower surface of the slide rail 1. The second roller 304, specifically, involves pre-embedding the slide rail 1 in front of the unloading gate of the garbage storage, connecting it to the concrete to form a whole. Then, the anchor 3 is installed on the slide rail 1. In use, one end of the steel wire rope is connected to the anchor 3, and the other end is connected to the garbage truck head. Then, the locking component 5 is pushed by the lever assembly 6 to release the gear 4, so that it no longer restricts the movement of the anchor 3. Then, the anchor 3 is adjusted so that the steel wire rope is taut. Then, the locking component 5 locks the gear 4, and the gear 4 locks the rack 2 fixed on the slide rail 1, so that the anchor 3 is fixed and the steel wire rope is always kept taut, preventing the garbage truck head from tilting up during unloading, avoiding vehicle damage or personnel injury, and can also adapt to garbage trucks of different sizes.

[0023] like Figure 4 As shown, the locking assembly 5 includes a pin 501 fixedly mounted on the side plate 302. One end of the pin 501 has a first keyway 502. A sleeve 503 is slidably mounted on the first keyway 502. The sleeve 503 has a first key tooth that matches the first keyway 502. One side of the gear 4 has a second keyway 505. One end of the sleeve 503 has a second key tooth 504 that cooperates with the second keyway 505. The gear 4 is rotatably connected to the pin 501. Specifically, when the sleeve 503 moves forward, the second key tooth 504 inside the sleeve 503 engages with the second keyway 505 on one side of the gear 4, thus restricting the rotation of the gear 4. At this time, the anchor 3 is fixed. When the sleeve 503 moves backward, the second key tooth 504 inside the sleeve 503 separates from the second keyway 505 on one side of the gear 4, and the sleeve 503 no longer restricts the rotation of the gear 4. At this time, the anchor 3 can move along the slide rail 1.

[0024] like Figure 2 As shown, a spring 506 is sleeved on the pin 501. One end of the spring 506 abuts against the side plate 302, and the other end of the spring 506 abuts against the sleeve 503. Specifically, the elastic force of the spring 506 keeps the second key tooth 504 inside the sleeve 503 engaged with the second keyway 505 on one side of the gear 4, so as to prevent the sleeve 503 from slipping out during operation.

[0025] like Figure 3As shown, the lever assembly 6 includes a lever 601 rotatably mounted on the top plate 301. One end of the lever 601 is hinged to a connecting rod 602 connected to the sleeve 503. Specifically, rotating the lever 601 causes the connecting rod 602 to push the sleeve 503 to move back and forth.

[0026] like Figure 3 As shown, the top of the lever 601 is provided with a mounting hole 603 for inserting a force-adding rod. Specifically, the lever principle is used to achieve the effect of saving effort.

[0027] like Figure 1 As shown, the slide rail 1 has stops 7 at both ends. Specifically, the stops 7 are used to prevent the anchor 3 from disengaging from the slide rail 1.

[0028] In practical use, the slide rail 1 is pre-embedded in front of the unloading gate of the garbage storage and connected to the concrete to form a whole. Then, the anchor 3 is installed on the slide rail 1. When in use, one end of the wire rope is connected to the anchor 3 and the other end is connected to the garbage truck head. Then, the lever 601 is rotated. The lever 601 drives the connecting rod 602 to push the sleeve 503 backward. The sleeve 503 no longer restricts the rotation of the gear 4. At this time, the anchor 3 can move along the slide rail 1. Then, the anchor 3 is adjusted so that the wire rope is taut. Then, the lever 601 is released. The sleeve 503 moves forward under the action of the spring 506 and locks the gear 4. The gear 4 locks the rack 2 fixed on the slide rail 1 to fix the anchor 3. The wire rope is always kept taut to prevent the garbage truck head from tilting up when unloading, avoiding vehicle damage or personnel injury. It can also adapt to garbage trucks of different sizes.

[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
