[0011] As a further technical scheme of the present application, the turnover assembly comprises two lower connecting seats fixed on the upper end surface of the moving plate, and upper connecting seats are fixed on both sides of the hopper.

[0012] As a further technical scheme of the present application, one side of the hopper is provided with a placing missing groove used in cooperation with the turnover baffle, a side groove is arranged on the inner wall of each placing missing groove, the control assembly comprises two electromagnets, and each electromagnet is fixed in the corresponding side groove.

[0013] As a further technical scheme of the present application, one side of the turnover baffle is fixed with a connecting block, a pull rope is hingedly connected to the upper end surface of the connecting block, two mounting seats are symmetrically fixed on the inner top of the adjacent connecting frame, a winding cylinder is rotatably arranged between the two mounting seats, the other end of the pull rope is fixedly connected to the inner wall of the winding cylinder, and each mounting seat is provided with a control unit used in cooperation with the winding cylinder.

[0014] As a further technical scheme of the present application, both ends of the winding cylinder are fixed with rotating shafts, one end of each rotating shaft is rotatably penetrated through the corresponding mounting seat and is fixed with a connecting disc, each control unit comprises a torsion spring, each torsion spring is fixed between the corresponding connecting disc and mounting seat, and each torsion spring is movably sleeved on the outer surface of the corresponding rotating shaft.

[0015] As a further technical scheme of the present application, a turnover push plate is rotatably arranged on the inner wall of the hopper and away from one end of the turnover baffle.

[0016] As a further technical scheme of the present application, one side of the hopper is provided with a through groove, a U-shaped frame is movably arranged in the through groove, the open end of the U-shaped frame faces the turnover push plate, a contact wheel is rotatably arranged on the inner wall of the U-shaped frame, and a driving unit used in cooperation with the U-shaped frame is arranged on the hopper.

[0017] As a further technical scheme of the present application, the driving unit comprises a mounting cylinder fixed on the outer side wall of the hopper, a hydraulic rod two is fixed on the inner wall of the mounting cylinder, and the distal end of the telescopic end of the hydraulic rod two is fixedly connected with the side wall of the U-shaped frame.

[0018] The beneficial effects of this invention are:

[0019] 1. During operation, the trestle bridge spans across the excavation pit. Dump trucks pass over the top of the trestle bridge and stop near the automated conveyor system. During this process, excavators and loaders at the bottom of the pit work together to dump the soil into the empty hopper below. The crane then rotates on the automated conveyor system (the crane can rotate automatically and intermittently, or be manually controlled, which is existing technology), thus moving the receiving base and the hopper containing the soil upwards. When the height of the receiving base is higher than the height of the dump truck's hopper, the crane stops rotating. At this point, the translation component moves the moving plate and the hopper containing the soil towards the dump truck. When the end of the hopper moves above the dump truck (at which point the soil in the hopper slides into the dump truck's hopper), the control component releases the tilting baffle. The hopper is sealed at the end, and then continues to move horizontally towards the transport truck until the end of the hopper reaches the middle of the truck bed. During this process, the tipping component causes the end of the hopper away from the truck to tip upward. At this time, the soil clods filled in the hopper fall into the truck bed under the influence of gravity. While this hopper is unloading soil, the empty hopper below the trestle is being filled with soil. After the hopper is unloaded, it moves back into the sliding slot. Then the crane rotates again to move the next hopper filled with soil to the unloading position. This cycle continues until the truck bed is full. Then the truck drives away, and the next empty truck moves to a position near the three-dimensional conveyor frame to prepare for the loading operation. This eliminates the need to drive the truck into the pit to load soil, reducing the risk of getting stuck and improving transport efficiency.

[0020] 2. When the moving plate and hopper move from the receiving base towards the dump truck, the tilting baffle and connecting block move together, pulling the end of the pull rope. During this process, the winding drum rotates to release the wound pull rope. When the end of the hopper is above the dump truck bed, the control component releases the tilting baffle from the end of the hopper. At this point, the pull rope wound on the winding drum is released, and the hopper continues to move horizontally towards the dump truck. During the movement of the hopper, the tilted pull rope pulls the connecting block and tilting baffle, allowing the tilting baffle to open at a larger angle during the movement and subsequent tilting of the hopper, reducing the obstruction to the movement of soil and facilitating the transfer of soil in the hopper.

[0021] 3. When the winding drum rotates forward to release the winding pull rope, the winding drum drives the rotating shaft and the connecting disc to rotate together, thereby causing the elastic deformation of the torsional spring and storing the elastic potential energy. When the soil blocks in the hopper are dumped, the hopper and the moving plate move towards the receiving base under the action of the translation assembly. In this process, the elastic potential energy stored in the torsional spring is gradually released, which promotes the reverse rotation of the winding drum to wind the pull rope, so as to avoid the excessively long pull rope that affects the movement of the hanging bracket on the three-dimensional conveying frame.

[0022] 4. When the hopper starts to tilt and overturn, the overturning push plate in the hopper will exert force on the soil blocks still in the hopper under the action of its own gravity, which promotes the soil blocks in the hopper to move towards the overturning baffle, thereby assisting the dumping and transfer of the soil blocks.

DETAILED DESCRIPTION

[0035] Reference Figures 1-10 A modular circulating foundation earthwork transportation system applied to a stack, comprising a three-dimensional conveying frame 2 arranged on one side of the stack body 1, wherein an annular track is arranged in the three-dimensional conveying frame 2, and a plurality of hanging brackets 3 are arranged on the three-dimensional conveying frame 2 through the annular track. This part of the structure is a prior art, and reference is made to a mechanical three-dimensional rotary parking garage. The construction of the stack body 1 and the three-dimensional conveying frame 2 and the rotation of the plurality of hanging brackets 3 are conventional technical means. The length of the stack 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 hanging bracket 3 is large enough and will not affect the earthwork operation of the excavator and the forklift on the hopper 8.

[0036] Each hanging bracket 3 comprises a receiving base 4 and two connecting frames 5. The receiving base 4 is provided with a sliding slot 6 on the side close to the stack body 1. A moving plate 7 is movably arranged in the sliding slot 6. A hopper 8 is movably arranged on the upper end surface of the moving plate 7. One end of the lower end surface of the hopper 8 is movably connected to the end of the moving plate 7 through a rotating shaft. A turnover baffle 9 is movably arranged on one side of the hopper 8. A control assembly for cooperating with the turnover baffle 9 is arranged on the hopper 8. A translation assembly and a limiting assembly for cooperating with the moving plate 7 are arranged on the receiving base 4. A turnover assembly for cooperating with the moving plate 7 is arranged on the receiving base 4.

[0037] In use, the trestle body 1 spans above the foundation pit, the dump truck 33 passes through the upper end face of the trestle body 1 and stops at a position close to the three-dimensional conveying frame 2, in the process, the excavator at the bottom of the foundation pit and the forklift cooperate with each other to dump the soil to be transferred 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 automatically and intermittently rotate on the three-dimensional conveying frame 2, or the rotation can be manually controlled, which is prior art), so as to transfer the receiving base 4 and the hopper 8 filled with soil upwards, when the height of the receiving base 4 is higher than the height of the car hopper of the dump truck 33, the hanger 3 stops rotating, at this time, under the action of the translation assembly, the moving plate 7 and the hopper 8 filled with soil are translated towards the dump truck 33, when the end of the hopper 8 moves above the dump truck 33 (at this time, the soil in the hopper 8 falls into the car hopper of the dump truck 33), the control assembly releases the blocking of the end of the hopper 8 by the turnover baffle 9, and then the hopper 8 continues to translate towards the dump truck 33 until the end of the hopper 8 moves to the middle of the car hopper of the dump truck 33, in the process, under the action of the turnover assembly, the end of the hopper 8 away from the dump truck 33 is turned upwards, at this time, the soil filled in the hopper 8 falls into the car hopper of the dump truck 33 under the action of gravity, in the process of unloading the soil, the empty hopper 8 below the trestle body 1 is filled with soil, then the hopper 8 unloaded of soil moves back to the sliding slot 6, and then the hanger 3 rotates again to rotate the next hopper 8 filled with soil to the unloading position, and the cycle continues until the car hopper of the dump truck 33 is filled, and then the dump truck 33 drives away, and the next empty dump truck 33 moves to a position close to the three-dimensional conveying frame 2 to prepare for the soil loading operation, without the need to drive the dump truck 33 into the foundation pit for soil loading, reducing the risk of getting stuck and improving the conveying efficiency.

[0038] The limiting assembly comprises limiting sliding blocks 10 fixed on both sides of the moving plate 7, and limiting sliding grooves 11 are formed in the inner wall of the sliding slot 6 to cooperate with the limiting sliding blocks 10.

[0039] The cooperation of the limiting sliding blocks 10 and the limiting sliding grooves 11 avoids the falling of the moving plate 7 from the sliding slot 6 during translation.

[0040] The translation assembly comprises a rack 12 fixed on the lower end face of the moving plate 7, a lower groove 13 is formed in the inner bottom of the sliding slot 6, a gear 14 is rotatably arranged on the inner wall of the lower groove 13, the gear 14 is in meshing connection with the rack 12, a cavity is formed in the receiving base 4, a motor is arranged in the cavity to cooperate with the rotation of the gear 14, the motor is provided with a self-locking function, and a plurality of rollers 15 are rotatably arranged on the lower end face of the moving plate 7.

[0041] The roller 15 is arranged to reduce the friction between the moving plate 7 and the sliding groove 6, facilitating the movement of the moving plate 7 and the hopper 8. When the moving plate 7 needs to be translated, the motor drives the gear 14 to rotate. Since the gear 14 is connected with the rack 12, the rotation of the gear 14 drives the rack 12, the moving plate 7 and the hopper 8 to translate.

[0042] The overturning assembly comprises two lower connecting seats 16 fixed to the upper end surface of the moving plate 7, and two upper connecting seats 17 fixed to the two sides of the hopper 8. Each upper connecting seat 17 is hingedly connected with a corresponding lower connecting seat 16.

[0043] In the initial state, the telescopic end of the hydraulic rod I 18 is in the retracted state, and the hopper 8 is in the horizontal state. When the hopper 8 needs to be overturned to dump the soil, the telescopic end of the hydraulic rod I 18 is extended to overturn the hopper 8.

[0044] The hopper 8 is provided with a placing groove 19 on one side for cooperating with the overturning baffle 9. The inner wall of each placing groove 19 is provided with a side groove, and the control assembly comprises two electromagnets 20, each of which is fixed in a corresponding side groove.

[0045] When the electromagnet 20 is powered on, it magnetically attracts the side wall of the overturning baffle 9, and at this time the overturning baffle 9 is in a vertical state and blocks the end of the hopper 8. When the electromagnet 20 is powered off, the electromagnet 20 no longer magnetically attracts the overturning baffle 9, and the soil accumulated in the hopper 8 collapses towards the direction of the overturning baffle 9, which is in contact with the overturning baffle 9 and is overturned by a certain angle, and then falls into the car hopper of the transport dump truck 33. When the hopper 8 starts to overturn, the included angle between the overturning baffle 9 and the placing groove 19 increases, so that the soil in the hopper 8 can slide into the car hopper of the transport dump truck 33.

[0046] The overturning baffle 9 is fixed with a connecting block 21, the upper end surface of the connecting block 21 is hingedly connected with a pull rope 22, the inner top of the adjacent connecting frame 5 is symmetrically fixed with two mounting seats 23, a winding cylinder 24 is rotatably arranged between the two mounting seats 23, the other end of the pull rope 22 is fixedly connected with the inner wall of the winding cylinder 24, and a control unit is arranged on each mounting seat 23 for cooperating with the winding cylinder 24.

[0047] When the mobile plate 7 and the hopper 8 move from the receiving base 4 to the transport dump truck 33, at this time, the turnover baffle 9 and the connecting block 21 move together, thereby pulling the end of the pull rope 22 to move, in the process, the winding drum 24 is matched to rotate, the wound pull rope 22 is released, when the end of the hopper 8 is above the vehicle hopper of the transport dump truck 33, at this time, the control assembly releases the sealing of the end of the hopper 8 by the turnover baffle 9, at this time, the wound pull rope 22 on the winding drum 24 is released, then the hopper 8 continues to translate towards the transport dump truck 33, in the process of moving, the inclined pull rope 22 pulls the connecting block 21 and the turnover baffle 9, so that the turnover baffle 9 can be turned open to a larger angle during the movement and subsequent turnover of the hopper 8, thereby reducing the obstruction to the movement of the soil, facilitating the transfer of the soil in the hopper 8.

[0048] Both ends of the winding drum 24 are fixed with rotating shafts 25, one end of each rotating shaft 25 is rotatably penetrated through the corresponding mounting seat 23 and is fixed with a connecting disc 26, each control unit comprises a torsion spring 27, each torsion spring 27 is fixed between the corresponding connecting disc 26 and the mounting seat 23, and each torsion spring 27 is movably sleeved 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 disc 26 to rotate, thereby causing the elastic deformation of the torsion spring 27 and storing the elastic potential energy, when the soil in the hopper 8 is completely poured, the hopper 8 and the mobile plate 7 move towards the receiving base 4 under the action of the translation assembly, in the process, the elastic potential energy stored in the torsion spring 27 is gradually released, thereby causing the winding drum 24 to rotate reversely to wind the pull rope 22, so as to avoid that the pull rope 22 is too long and affects the movement of the hanger 3 on the three-dimensional conveying frame 2.

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

[0051] When the hopper 8 starts to tilt and turn over, the turnover push plate 28 in the hopper 8 applies a force to the soil still in the hopper 8 under the action of its own gravity, thereby causing the soil in the hopper 8 to move towards the direction close to the turnover baffle 9, and assisting in the pouring and transfer of the soil.

[0052] A through slot is formed in one side of the hopper 8, a U-shaped frame 29 is movably arranged in the through slot, the open end of the U-shaped frame 29 faces the turnover push plate 28, a contact wheel 30 is rotatably arranged on the inner wall of the U-shaped frame 29, and a driving unit that cooperates with the U-shaped frame 29 is arranged on the hopper 8.

[0053] When the hopper 8 starts to tilt and the turnover push plate 28 cannot rotate, the U-shaped frame 29 and the abutting wheel 30 are driven by the driving unit to move towards the direction of the turnover push plate 28, thereby cooperating with the turnover of the turnover push plate 28.

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

[0055] In the initial state, the telescopic end of the hydraulic rod 32 is in the contracted state, and when it is needed to push the turnover push plate 28 to turn over, the telescopic end of the hydraulic rod 32 is elongated to push the U-shaped frame 29 and the abutting wheel 30 to move towards the direction of the turnover push plate 28.

[0056] In use, the construction of the trestle body 1 and the three-dimensional conveying frame 2 and the rotation of the plurality of hanging frames 3 are conventional technical means, and 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.

[0057] In use, the trestle body 1 spans above the foundation pit, the dump truck 33 passes through the upper end face of the trestle body 1 and stops at a position close to the three-dimensional conveying frame 2, in the process, the excavator at the bottom of the foundation pit and the forklift cooperate with each other to dump the soil to be transferred 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 automatically rotate intermittently on the three-dimensional conveying frame 2, or can be manually controlled to rotate, which is prior art), so as to transfer the receiving base 4 and the hopper 8 filled with soil upwards, when the height of the receiving base 4 is higher than the height of the car hopper of the dump truck 33, the hanger 3 stops rotating, at this time, under the action of the translation assembly, the moving plate 7 and the hopper 8 filled with soil are translated towards the dump truck 33, when the end of the hopper 8 moves above the dump truck 33 (at this time, the soil in the hopper 8 slides into the car hopper of the dump truck 33), the control assembly releases the blocking of the end of the hopper 8 by the turnover baffle 9, and then the hopper 8 continues to translate towards the dump truck 33 until the end of the hopper 8 moves to the middle of the car hopper of the dump truck 33, in the process, under the action of the turnover assembly, the end of the hopper 8 away from the dump truck 33 is turned upwards, at this time, the soil filled in the hopper 8 falls into the car hopper of the dump truck 33 under the action of gravity, in the process of unloading the soil, the empty hopper 8 below the trestle body 1 is filled with soil, and then the hopper 8 unloaded of soil moves back to the sliding slot 6, and then the hanger 3 rotates again to rotate the next hopper 8 filled with soil to the unloading position, and the cycle continues until the car hopper of the dump truck 33 is filled, and then the dump truck 33 drives away, and the next empty dump truck 33 moves to a position close to the three-dimensional conveying frame 2 to prepare for soil loading operation, without the need to drive the dump truck 33 into the foundation pit for soil loading, reducing the risk of getting stuck and improving the conveying efficiency;

[0058] When the electromagnet 20 is powered on, it magnetically adsorbs the side wall of the turnover baffle 9, at this time, the turnover baffle 9 is in a vertical state and blocks the end of the hopper 8, when the electromagnet 20 is powered off, the electromagnet 20 no longer magnetically adsorbs the turnover baffle 9, and the soil accumulated in the hopper 8 collapses towards the turnover baffle 9, which abuts against the turnover baffle 9 and turns a certain angle, and then falls into the car hopper of the dump truck 33, when the hopper 8 starts to turn, the included angle between the turnover baffle 9 and the placing slot 19 increases, which facilitates the soil in the hopper 8 to slide into the car hopper of the dump truck 33;

[0059] When the mobile plate 7 and the hopper 8 move from the receiving base 4 to the transport dump truck 33, at this time, the turnover baffle 9 and the connecting block 21 move together, thereby pulling the end of the pull rope 22 to move, in the process, the winding drum 24 is matched to rotate, the wound pull rope 22 is released, when the end of the hopper 8 is above the car hopper of the transport dump truck 33, at this time, the control assembly releases the sealing of the end of the hopper 8 by the turnover baffle 9, at this time, the wound pull rope 22 on the winding drum 24 is released, then the hopper 8 continues to translate towards the transport dump truck 33, in the process of moving, the inclined pull rope 22 pulls the connecting block 21 and the turnover baffle 9, so that the turnover baffle 9 can be turned open to a larger angle during the movement and subsequent turnover of the hopper 8, thereby reducing the obstruction to the movement of the soil, facilitating the transfer of the soil in the hopper 8;

[0060] 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 disc 26 to rotate, thereby causing the elastic deformation of the torsional spring 27 and storing elastic potential energy, when the soil in the hopper 8 is dumped, the hopper 8 and the mobile plate 7 move towards the receiving base 4 under the action of the translation assembly, in the process, the elastic potential energy stored in the torsional spring 27 is gradually released, so that the winding drum 24 reversely rotates to wind the pull rope 22, thereby avoiding the excessively long suspension of the pull rope 22, which affects the movement of the hanger 3 on the three-dimensional conveying frame 2.

[0061] When the hopper 8 starts to tilt and turn over, the turnover push plate 28 in the hopper 8 applies force to the soil still in the hopper 8 under the action of its own gravity, so as to facilitate the movement of the soil in the hopper 8 towards the direction close to the turnover baffle 9, thereby assisting the dumping and transfer of the soil, when the hopper 8 starts to tilt and turn over, the turnover push plate 28 cannot rotate, at this time, the U-shaped frame 29 and the abutting wheel 30 are driven by the driving unit to move towards the turnover push plate 28, thereby assisting the turnover of the turnover push plate 28.
