[0002] Foundation pits are spaces below the ground excavated for the construction of building (structure) foundations and underground buildings (structures). Foundation pits can also be divided into primary, secondary and tertiary levels. Primary foundation pits include important projects or supporting structures as part of the main structure, with an excavation depth of more than 10 meters and close to adjacent buildings or important facilities; secondary foundation pits are between primary and tertiary; and tertiary foundation pits refer to foundation pits with an excavation depth of less than 7 meters and no special requirements for the surrounding environment.

[0018] Beneficial effects of the present invention:

[0019] 1. When in use, the trestle body spans across the top of the foundation pit, and the transport muck truck passes through the upper end surface of the trestle body and stops at a position close to the three-dimensional conveying frame. In this process, the excavator and the forklift at the bottom of the foundation pit cooperate with each other to dump the soil blocks to be transferred and transported inside the foundation pit into the empty hopper below, and then the hanger rotates on the three-dimensional conveying frame (the hanger can rotate automatically and intermittently on the three-dimensional conveying frame, or can be manually controlled to rotate, which is the prior art), so as to transfer the receiving base and the hopper containing the soil blocks upward. When the height of the receiving base is higher than the height of the bucket of the transport muck truck, the hanger stops rotating. At this time, under the action of the translation component, the moving plate and the bucket containing the soil blocks are translated toward the transport muck truck. When the end of the hopper moves to the top of the transport muck truck (at this time, the soil blocks in the hopper slide into the bucket of the transport muck truck), the control component releases the flip baffle to the material The end of the bucket is blocked, and then the bucket continues to move horizontally toward the direction of the transport dump truck until the end of the bucket moves to the middle position of the bucket of the transport dump truck. In this process, under the action of the flipping assembly, the end of the bucket away from the transport dump truck is flipped upward. At this time, the soil blocks filled in the bucket fall into the bucket of the transport dump truck under the action of gravity. During the process of unloading soil from this bucket, the empty bucket under the trestle body is loaded with soil, and then the bucket after unloading the soil will move back into the sliding slot, and then the hanger will rotate again to rotate the next bucket filled with soil blocks to the unloading position, and this cycle will continue until the bucket of the transport dump truck is full, and then the transport dump truck drives away, and the next empty transport dump truck moves to a position close to the three-dimensional conveying frame to prepare for loading operations. There is no need to drive the transport dump truck into the foundation pit to load soil, which reduces the risk of the vehicle being stuck and improves the transportation efficiency.

[0020] 2. When the moving plate and the hopper move from the receiving base toward the transport dump truck, the flip baffle and the connecting block move together, thereby pulling the end of the pull rope to move together. During this process, the winding drum rotates in coordination to release the wound pull rope. When the end of the hopper is above the bucket of the transport dump truck, the control component releases the blockage of the end of the hopper by the flip baffle. At this time, the pull rope wound on the winding drum is released, and then the hopper continues to translate toward the direction of the transport dump truck. During the movement of the hopper, the inclined pull rope will pull the connecting block and the flip baffle, causing the flip baffle to flip open to a larger angle during the movement and subsequent flipping of the hopper, thereby reducing the obstruction to the movement of soil blocks and facilitating the transfer of soil blocks in the hopper.

[0021] 3. When the winding drum rotates forward to release the wound pull rope, the winding drum drives the rotating shaft and the connecting disk to rotate together, thereby causing elastic deformation of the torsion spring and storing elastic potential energy. When the soil in the hopper is dumped, the hopper and the movable plate move closer to the receiving base under the action of the translation assembly. During this process, the elastic potential energy stored in the torsion spring is gradually released, prompting the winding drum to rotate in the opposite direction and wind the pull rope to avoid the suspended pull rope being too long, which affects the movement of the hanger on the three-dimensional conveyor frame.

[0022] 4. When the hopper begins to tilt and flip, the flip push plate in the hopper will exert force on the soil blocks still in the hopper under the action of its own gravity, causing the soil blocks in the hopper to move toward the direction close to the flip baffle, thereby assisting in the dumping and transfer of the soil blocks.

DETAILED DESCRIPTION

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0035] Reference Figure 1-Figure 10 A modular circulating foundation pit earthwork transportation system applied to a trestle comprises a three-dimensional conveying frame 2 arranged on one side of a trestle body 1, a circular track is arranged inside the three-dimensional conveying frame 2, and a plurality of hangers 3 are arranged on the three-dimensional conveying frame 2 through the circular track. This part of the structure is a prior art. With reference to a mechanical three-dimensional rotary parking garage, the construction of the trestle body 1 and the three-dimensional conveying frame 2 and the rotation of the plurality of hangers 3 are conventional technical means. The length of the trestle body 1 and the height of the three-dimensional conveying frame 2 can be modularly constructed according to the size of the foundation pit. The size of the hanger 3 is large enough and will not affect the loading operation of the hopper 8 by the excavator and the forklift.

[0036] Each hanger 3 includes a receiving base 4 and two connecting frames 5. A sliding groove 6 is provided on the receiving base 4 on one side close to the pier body 1. A movable plate 7 is movably arranged in the sliding groove 6. A hopper 8 is movably arranged on the upper end surface of the movable plate 7. One end of the lower end surface of the hopper 8 is rotatably connected to the end of the movable plate 7 through a rotating shaft. A flip baffle 9 is rotatably arranged on one side of the hopper 8. A control component for cooperating with the flip baffle 9 is arranged on the hopper 8. A translation component and a limit component for cooperating with the movable plate 7 are arranged on the receiving base 4. A flip component for cooperating with the movable plate 7 is arranged on the receiving base 4.

[0037] When in use, the trestle body 1 spans across the top of the foundation pit, and the transport muck truck 33 passes through the upper end surface of the trestle body 1 and stops at a position close to the three-dimensional conveying frame 2. During this process, the excavator and the forklift at the bottom of the foundation pit cooperate with each other to dump the soil blocks to be transferred and transported inside the foundation pit into the empty hopper 8 below, and then the hanger 3 rotates on the three-dimensional conveying frame 2 (the hanger 3 can be automatically intermittently rotated on the three-dimensional conveying frame 2, or it can be manually controlled to rotate, which is the prior art), so as to transfer the receiving base 4 and the hopper 8 containing the soil blocks upward. When the height of the receiving base 4 is higher than the height of the bucket of the transport muck truck 33, the hanger 3 stops rotating. At this time, under the action of the translation component, the moving plate 7 and the hopper 8 containing the soil blocks are translated toward the transport muck truck 33. When the end of the hopper 8 moves to the top of the transport muck truck 33 (at this time, the soil blocks in the hopper 8 slide into the bucket of the transport muck truck 33), the control component releases the flip baffle 9 to the hopper 8 The end is blocked, and then the hopper 8 continues to translate in the direction of the transport muck truck 33 until the end of the hopper 8 moves to the middle position of the bucket of the transport muck truck 33. In this process, under the action of the flip assembly, the hopper 8 is caused to flip upward away from the end of the transport muck truck 33. At this time, the soil blocks filled in the hopper 8 fall into the bucket of the transport muck truck 33 under the action of gravity. During the process of unloading soil, the empty hopper 8 under the trestle body 1 is loaded with soil, and then the hopper 8 after unloading the soil will move back into the sliding groove 6, and then the hanger 3 rotates again to rotate the next hopper 8 filled with soil blocks to the unloading position, and this cycle is repeated until the bucket of the transport muck truck 33 is full, and then the transport muck truck 33 drives away, and the next empty transport muck truck 33 moves to a position close to the three-dimensional conveying frame 2 to prepare for soil loading operations. There is no need to drive the transport muck truck 33 to the inside of the foundation pit to load soil, which reduces the risk of getting stuck and improves the transportation efficiency.

[0038] The limiting assembly includes limiting sliding blocks 10 fixed to both sides of the moving plate 7 , and limiting sliding grooves 11 used in conjunction with the limiting sliding blocks 10 are provided on the inner wall of the sliding groove 6 .

[0039] The cooperation between the limiting sliding block 10 and the limiting sliding groove 11 can prevent the movable plate 7 from falling off from the sliding groove 6 during the translation process.

[0040] The translation assembly includes a rack 12 fixed to the lower end surface of the moving plate 7, a lower groove 13 is provided at the inner bottom of the sliding groove 6, a gear 14 is rotatably provided on the inner wall of the lower groove 13, the gear 14 is meshed and connected with the rack 12, a cavity is provided in the receiving base 4, a motor is provided in the cavity for rotating with the gear 14, the motor is provided with a self-locking function, and a plurality of rollers 15 are rotatably provided on the lower end surface of the moving plate 7.

[0041] The roller 15 is provided to reduce the friction between the moving plate 7 and the sliding groove 6, so as to facilitate the movement of the moving plate 7 and the hopper 8. When it is necessary to cause the moving plate 7 to translate, the motor drives the gear 14 to rotate. Since the gear 14 is suitable for meshing connection with the rack 12, when the gear 14 rotates, it drives the rack 12, the moving plate 7 and the hopper 8 to translate.

[0042] The flip assembly includes two lower connecting seats 16 fixed to the upper end surface of the moving plate 7, and upper connecting seats 17 are fixed on both sides of the hopper 8. A hydraulic rod 18 is hinged between each upper connecting seat 17 and the corresponding lower connecting seat 16.

[0043] In the initial state, the telescopic end of the hydraulic rod 18 is in a retracted state, and the hopper 8 is in a horizontal state. When the hopper 8 needs to be turned over to empty the materials, the telescopic end of the hydraulic rod 18 is extended to cause the hopper 8 to turn over.

[0044] A placement notch 19 for cooperating with the flip baffle 9 is provided on one side of the hopper 8, and a side groove is provided on the inner wall of each placement notch 19. The control component includes two electromagnets 20, and each electromagnet 20 is fixed in a corresponding side groove.

[0045] When the electromagnet 20 is energized, it magnetically adsorbs the side wall of the flip baffle 9. At this time, the flip baffle 9 is in a vertical state, blocking the end of the hopper 8. When the electromagnet 20 is powered off, the electromagnet 20 no longer magnetically adsorbs the flip baffle 9, and the soil blocks accumulated in the hopper 8 will collapse toward the flip baffle 9, flipping the flip baffle 9 at a certain angle, and then falling into the bucket of the dump truck 33. When the hopper 8 starts to flip, the angle between the flip baffle 9 and the placement slot 19 becomes larger, which makes it convenient for the soil blocks in the hopper 8 to slide into the bucket of the dump truck 33.

[0046] A connecting block 21 is fixed to one side of the flip baffle 9, and a pull rope 22 is hinged on the upper end surface of the connecting block 21. Two mounting seats 23 are symmetrically fixed to the inner top of the adjacent connecting frame 5. A winding drum 24 is rotatably arranged between the two mounting seats 23. The other end of the pull rope 22 is fixedly connected to the inner wall of the winding drum 24. A control unit for use with the winding drum 24 is provided on each mounting seat 23.

[0047] When the movable plate 7 and the hopper 8 move from the receiving base 4 to the transport dump truck 33, the flip baffle 9 and the connecting block 21 move together, thereby pulling the end of the pull rope 22 to move together. During this process, the winding drum 24 cooperates to rotate and releases the wound pull rope 22. When the end of the hopper 8 is above the bucket of the transport dump truck 33, the control component releases the blockage of the flip baffle 9 on the end of the hopper 8. At this time, the pull rope 22 wound on the winding drum 24 is released, and then the hopper 8 continues to translate toward the direction of the transport dump truck 33. During the movement of the hopper 8, the inclined pull rope 22 will pull the connecting block 21 and the flip baffle 9, so that the flip baffle 9 can be flipped open at a larger angle during the movement and subsequent flipping of the hopper 8, thereby reducing the obstruction to the movement of soil blocks and facilitating the transfer of soil blocks in the hopper 8.

[0048] A rotating shaft 25 is fixed at both ends of the winding drum 24, one end of each rotating shaft 25 rotates through the corresponding mounting seat 23 and is fixed with a connecting disk 26, each control unit includes a torsion spring 27, each torsion spring 27 is fixed between the corresponding connecting disk 26 and the mounting seat 23, and each torsion spring 27 is movably mounted on the outer surface of the corresponding rotating shaft 25.

[0049] When the winding drum 24 rotates forward to release the wound pull rope 22, the winding drum 24 drives the rotating shaft 25 and the connecting plate 26 to rotate together, thereby causing elastic deformation of the torsion spring 27 and storing elastic potential energy. When the soil blocks in the hopper 8 are dumped, the hopper 8 and the movable plate 7 move closer to the receiving base 4 under the action of the translation assembly. During this process, the elastic potential energy stored in the torsion spring 27 is gradually released, prompting the winding drum 24 to rotate in the opposite direction to wind the pull rope 22, thereby preventing the suspended pull rope 22 from being too long and affecting the movement of the hanger 3 on the three-dimensional conveying frame 2.

[0050] A flip push plate 28 is rotatably provided on the inner wall of the hopper 8 and at one end away from the flip baffle 9 .

[0051] When the hopper 8 starts to tilt and flip, the flip push plate 28 in the hopper 8 will exert a force on the soil blocks still in the hopper 8 under the action of its own gravity, prompting the soil blocks in the hopper 8 to move toward the flip baffle 9, thereby assisting the dumping and transfer of the soil blocks.

[0052] A through slot is provided on one side of the hopper 8, in which a U-shaped frame 29 is movably arranged, the open end of the U-shaped frame 29 faces the flip push plate 28, a resistance wheel 30 is rotatably arranged on the inner wall of the U-shaped frame 29, and a driving unit used in conjunction with the U-shaped frame 29 is provided on the hopper 8.

[0053] When the hopper 8 begins to tilt and flip, and the flip push plate 28 cannot rotate, the driving unit pushes the U-shaped frame 29 and the abutment wheel 30 to move toward the flip push plate 28 to cooperate with the flipping of the flip push plate 28 .

[0054] The driving unit includes a mounting cylinder 31 fixed on the outer wall of the hopper 8 , a hydraulic rod 32 is fixed on the inner wall of the mounting cylinder 31 , and the end of the telescopic end of the hydraulic rod 32 is fixedly connected to the side wall of the U-shaped frame 29 .

[0055] In the initial state, the telescopic end of the hydraulic rod 2 32 is in a retracted state. When the flip push plate 28 needs to be flipped, the telescopic end of the hydraulic rod 2 32 extends to push the U-shaped frame 29 and the abutment wheel 30 to move toward the flip push plate 28 .

[0056] When the present invention is used, the construction of the trestle body 1 and the three-dimensional conveyor frame 2 and the rotation of the multiple hangers 3 are conventional technical means. The length of the trestle body 1 and the height of the three-dimensional conveyor frame 2 can be modularly constructed according to the size of the foundation pit;

[0057] When in use, the trestle body 1 spans across the top of the foundation pit, and the transport muck truck 33 passes through the upper end surface of the trestle body 1 and stops at a position close to the three-dimensional conveying frame 2. During this process, the excavator and the forklift at the bottom of the foundation pit cooperate with each other to dump the soil blocks to be transferred and transported inside the foundation pit into the empty hopper 8 below, and then the hanger 3 rotates on the three-dimensional conveying frame 2 (the hanger 3 can be automatically intermittently rotated on the three-dimensional conveying frame 2, or it can be manually controlled to rotate, which is the prior art), so as to transfer the receiving base 4 and the hopper 8 containing the soil blocks upward. When the height of the receiving base 4 is higher than the height of the bucket of the transport muck truck 33, the hanger 3 stops rotating. At this time, under the action of the translation component, the moving plate 7 and the hopper 8 containing the soil blocks are translated toward the transport muck truck 33. When the end of the hopper 8 moves to the top of the transport muck truck 33 (at this time, the soil blocks in the hopper 8 slide into the bucket of the transport muck truck 33), the control component releases the flip baffle 9 to the hopper 8 The end is blocked, and then the hopper 8 continues to move horizontally towards the direction of the transport muck truck 33 until the end of the hopper 8 moves to the middle position of the bucket of the transport muck truck 33. In this process, under the action of the turning component, the hopper 8 is caused to turn upward away from the end of the transport muck truck 33. At this time, the soil blocks filled in the hopper 8 fall into the bucket of the transport muck truck 33 under the action of gravity. During the process of unloading soil, the empty hopper 8 under the trestle body 1 is loaded with soil, and then the hopper 8 after unloading the soil will move back into the sliding slot 6, and then the hanger 3 rotates again to rotate the next hopper 8 filled with soil blocks to the unloading position, and this cycle is repeated until the bucket of the transport muck truck 33 is full, and then the transport muck truck 33 drives away, and the next empty transport muck truck 33 moves to a position close to the three-dimensional conveying frame 2 to prepare for soil loading operations. There is no need to drive the transport muck truck 33 to the inside of the foundation pit to load soil, which reduces the risk of getting stuck and improves the transportation efficiency.

[0058] When the electromagnet 20 is powered on, it magnetically adsorbs the side wall of the flip baffle 9. At this time, the flip baffle 9 is in a vertical state, blocking the end of the hopper 8. When the electromagnet 20 is powered off, the electromagnet 20 no longer magnetically adsorbs the flip baffle 9, and the soil blocks accumulated in the hopper 8 collapse toward the flip baffle 9, turning the flip baffle 9 to a certain angle, and then falling into the bucket of the transport muck truck 33. When the hopper 8 starts to flip, the angle between the flip baffle 9 and the placement slot 19 becomes larger, which facilitates the soil blocks in the hopper 8 to slide into the bucket of the transport muck truck 33.

[0059] When the moving plate 7 and the hopper 8 move from the receiving base 4 to the transport muck truck 33, the flip baffle 9 and the connecting block 21 move together, thereby pulling the end of the pull rope 22 to move together. In this process, the winding drum 24 rotates in coordination to release the wound pull rope 22. When the end of the hopper 8 is above the bucket of the transport muck truck 33, the control component releases the blocking of the flip baffle 9 on the end of the hopper 8. At this time, the pull rope 22 wound on the winding drum 24 is released, and then the hopper 8 continues to move horizontally in the direction of the transport muck truck 33. During the movement of the hopper 8, the inclined pull rope 22 will pull the connecting block 21 and the flip baffle 9, so that the flip baffle 9 can be flipped to a larger angle during the movement and subsequent flipping of the hopper 8, thereby reducing the obstruction to the movement of the soil blocks and facilitating the transfer of the soil blocks in the hopper 8.

[0060] When the winding drum 24 rotates forward to release the wound rope 22, the winding drum 24 drives the rotating shaft 25 and the connecting plate 26 to rotate together, thereby causing elastic deformation of the torsion spring 27 and storing elastic potential energy. When the soil blocks in the hopper 8 are dumped, the hopper 8 and the moving plate 7 move closer to the receiving base 4 under the action of the translation assembly. During this process, the elastic potential energy stored in the torsion spring 27 is gradually released, prompting the winding drum 24 to rotate in the opposite direction to wind the rope 22, thereby preventing the rope 22 from being suspended too long and affecting the movement of the hanger 3 on the three-dimensional conveying frame 2.

[0061] When the hopper 8 begins to tilt and flip, the flip push plate 28 in the hopper 8 will exert a force on the soil blocks still in the hopper 8 under the action of its own gravity, prompting the soil blocks in the hopper 8 to move toward the direction close to the flip baffle 9, thereby assisting in the dumping and transfer of the soil blocks. When the hopper 8 begins to tilt and flip, the flip push plate 28 cannot rotate. At this time, the U-shaped frame 29 and the resistance wheel 30 are pushed toward the direction of the flip push plate 28 by the drive unit, thereby cooperating in the flipping of the flip push plate 28.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
