Description

Technical Field

[0002] A modular foundation pit earthwork transportation system is mainly used for the fast and efficient transportation of earthwork during the foundation pit excavation process on the construction site. During the foundation pit excavation process, a large amount of earthwork will be generated. The modular foundation pit earthwork transportation system can transport the earthwork from the foundation pit to the designated stacking location or directly transport it out. Efficient earthwork transportation can reduce the use of manpower and machinery, reduce construction costs, and adapt to different construction needs. The modular foundation pit earthwork transportation system is an important equipment for improving efficiency, reducing costs, and protecting the environment in modern construction.

[0003] The Chinese patent authorization announcement number is CN114715609B, and its name is a foundation pit earthwork lifting and transportation device, which includes parallel side frames, and the inner sides of both ends of the side frames are provided with rotating conveying rollers, and also includes a bracket, a swinging side support and a connecting piece; the bracket is fixed to the outer side of one end of the side frame, and the swinging side support is rotatably connected to the bracket, and the end of the swinging side support away from the side frame is provided with a rotating conveying roller, and the connecting piece is rotatably connected to the other end of the swinging side support, and the brackets on both sides are provided with rotating mounting parts, and the connecting part and the mounting part are connected by the setting adjustment parts, and the conveying rollers on the inner side of the side frame and the swinging side support are provided with the same conveyor belt. Its beneficial effects are: it solves the problem of material leakage at the joint, and the two ends of the device can adjust the angle direction, which is more conducive to loading and unloading operations, and realizes that multiple devices can be set on the foundation pit slope and connected end to end, which not only simplifies the work of installation and disassembly, but also makes adjustment very convenient;

[0020] Advantages of the present invention:

[0021] 1. In the vertical transportation mechanism of the present invention, the transportation box is used to load earthwork. It is connected to the reel through a winding rope. The motor is rotated to drive the rotating shaft, and the rotating shaft drives the reel to rotate, thereby lifting or lowering the transportation box to achieve the vertical transportation of earthwork. There is a rotating plate at the bottom of the transportation box, which is connected to the motor through a rotating mechanism. When the motor drives the first rotating gear to rotate, the rotating plate is driven to rotate through the first rack. The rotating plate rotates through the rotating wheel, so that the rotating plate rotates obliquely, pouring the earthwork in the transportation box into the trolley. The trolley is used to transport earthwork. The trolley cooperates with the slide rail on the bottom plate through the universal wheel and can move on the slide rail, combining vertical transportation and horizontal transportation, simplifying the operation process and reducing the steps of manual handling.

[0022] 2. The connecting plate and the connecting frame of the present invention are used to connect the electric telescopic rod and the second rotating gear, realizing the telescoping and rotation of the auxiliary wheel. The second rotating gear drives the engaged second rack to move, so that the connecting plate moves to both sides of the trolley, and then the position of the auxiliary wheel is moved through the telescoping of the electric telescopic rod. During transportation, especially on uneven or rough terrains, the position adjustment of the auxiliary wheel can provide better support, reduce the tilt and shaking of the trolley, and enhance the overall stability. By adjusting the position of the auxiliary wheel, the best support points can be provided on different terrains, reducing the tilt and shaking of the trolley, thereby enhancing the overall stability.

[0023] 3. The leveling mechanism on the trolley of the present invention is used to level the earthwork during transportation. The winding wheel drives the leveling rod to move through the pulling rope, and the earthwork in the trolley is evenly leveled by the leveling rod, which can reduce the tilt and shaking caused by the center of gravity shift of the earthwork during transportation, thereby improving the transportation stability. The stable transportation state can reduce accidents caused by the sliding of the earthwork and improve the safety during transportation. Description of the Drawings

[0035] Multiple sets of universal wheels 24 are connected to the bottom of the trolley 15. Brake pads are connected to the universal wheels 24. The universal wheels 24 are arranged in cooperation with the slide rails 3 on the mounting plate 2. A fixed block 25 is connected to the trolley 15. A push rod 26 is connected to the fixed block 25.

[0036] Multiple sets of auxiliary stabilizing mechanisms are connected to both sides of the trolley 15.

[0037] Working principle of the present invention: The bottom plate 1 is the base of the entire system. In the vertical transportation mechanism, the transportation box 9 is used to load earthwork and is connected to the reel 7 through the winding rope 8. The rotation motor 5 drives the rotating shaft 6, and the rotating shaft 6 drives the reel 7 to rotate, thereby lifting or lowering the transportation box 9 to achieve the vertical transportation of earthwork. There is a rotating plate 10 at the bottom of the transportation box 9, which is connected to the electric motor through a rotating mechanism (rotating gear one 11 and rack one 12). When the electric motor drives the rotating gear one 11 to rotate, the rotating plate 10 is driven to rotate through the rack one 12. The rotating plate 10 rotates through the rotating wheel 14, causing the rotating plate 10 to rotate obliquely and pour out the earthwork in the transportation box 9 into the trolley 15. The trolley 15 is used to transport earthwork. The trolley 15 cooperates with the slide rail 3 on the bottom plate 1 through the universal wheels 24 and can move on the slide rail 3. The protective plate 13 is located between the rotating plate 10 and the transportation box 9 and is used to maintain the fixation of the rotating plate 10. The trolley 15 is connected with a fixed block 25 and a push rod 26 for pushing the trolley 15. The leveling mechanism includes a leveling rod 22 and a winding wheel 23, which are used to level the earthwork during transportation. The winding wheel 23 drives the leveling rod 22 to move through the pulling rope to level the earthwork in the trolley 15 and prevent unstable transportation;

[0038] The auxiliary stability mechanism includes an electric telescopic rod 19 and an auxiliary wheel 21, which are used to provide additional stability and support during transportation. The connecting plate 18 and the connecting frame 16 are used to connect the electric telescopic rod 19 and the rotating gear two 17 to achieve the telescopic and rotation of the auxiliary wheel 21. The meshing rack two 20 is driven to move by the rotating gear two 17, causing the connecting plate 18 to move to both sides of the trolley 15. Then, through the telescopic movement of the electric telescopic rod 19, the position of the auxiliary wheel 21 is adjusted. During transportation, especially on uneven or rough terrains, the position adjustment of the auxiliary wheel 21 can provide better support, reduce the tilt and shake of the trolley 15, and enhance the overall stability. When the amount of earthwork loaded on the trolley 15 is different, by adjusting the height of the auxiliary wheel 21, the weight can be better distributed to prevent the trolley 15 from losing balance due to uneven load;

[0039] The earthwork is loaded into the transportation box 9 through the trolley 15, and then the earthwork is lifted to a specified height through the vertical transportation mechanism. During transportation, the rotating plate 10 and the leveling mechanism stir and level the earthwork, and the trolley 15 and the auxiliary stability mechanism ensure the stability and safety during transportation.

[0040] The above has described an embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention.
