Description

Technical Field

[0001] This invention relates to the field of deep foundation pit engineering machinery technology, and more specifically, to an electric hoisting and automatic dumping device for deep foundation pit excavated soil. Background Technology

[0002] In deep foundation pit construction, traditional slag removal and transportation often uses fixed hooks or simple baskets. During the lifting process, the balance cannot be automatically adjusted according to the real-time load, which poses obvious safety hazards. When multiple load-bearing buckets are lifted at the same time, the difference in load can easily cause the overall center of gravity to shift, leading to lifting swaying or even overturning risks, which seriously restricts the safety and efficiency of lifting operations. In the unloading stage after hoisting, traditional methods often rely on tilting the crane boom at a single angle or manual knocking. Due to its water content and stickiness, the excavated soil easily adheres to the barrel wall, resulting in incomplete unloading in one go. This not only reduces the efficiency of a single transport but also requires repeated operations or manual cleaning. This incomplete unloading method wastes time and equipment, becoming a key bottleneck restricting the efficiency of excavation from deep foundation pits. While some lifting devices or vibratory dumping devices with balancing functions exist on the market, they are usually single-function and independent of each other. There is a lack of a device that can integrate adaptive balance adjustment and efficient automatic dumping functions, making it impossible to achieve dynamic and automatic connection and optimization between lifting stability and thorough dumping. In view of this, we propose an electric lifting and automatic dumping device for deep foundation pit slag. Summary of the Invention

[0003] The purpose of this invention is to provide an electric hoisting and automatic dumping device for deep foundation pit slag, so as to solve the technical problems of hoisting instability caused by uneven load and incomplete automatic dumping in traditional slag transportation.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an electric hoisting and automatic dumping device for deep foundation pit slag, comprising a frame, a hoisting mechanism, a dumping mechanism, a winding assembly and a carrying bucket, wherein the dumping mechanism comprises a dumping module and a balancing module; The tilting module includes a shaft arranged below the hoisting mechanism; The shaft end is hinged with several support frames in a ring array. The support frames can be brought together or unfolded, and can be rotated axially to form a gathered state, a horizontally flat shape, or an umbrella shape. The balancing module includes rigid tubes sleeved inside the support frame, and each rigid tube has several adjustment slots arranged in a linear array on its side surface. Each of the rigid tubes has an internal sealing sleeve with a guide rod corresponding to the position of the adjustment groove, and a secondary sealing cavity is formed between adjacent guide rods; Each of the guide rods is fixedly connected to a hook on its side surface, and the carrying bucket can be hung on the hook; The shaft end is provided with a manifold that communicates with the rigid tube, and the manifold and the flow space of the several rigid tubes form a total sealed cavity. When several support frames are brought together, the weight difference of any bearing tank drives the liquid in the rigid tube to flow in the total sealed cavity through the guide rod, adjusting the distance between each tank and the shaft, and distributing it evenly with the shaft as the center axis. When the support frame unfolds into a flat or umbrella shape, the soil inside the bucket partially tilts, causing a change in weight. This triggers a hydraulic linkage, driving the bucket to move back and forth. Utilizing inertia and the tilting of the bucket, the soil is thoroughly emptied. This invention, through the linkage design of the tilting and balancing modules, utilizes the weight difference of each carrying bucket to drive the hydraulic system when the support frame is closed. This allows the bucket to automatically adjust its distance from the shaft, achieving a uniform distribution with the shaft as the center of gravity. This effectively improves the balance and safety of the hoisting, solving the technical problems of unbalanced loads and easy tipping when multiple lifting points are supported. When the support frame unfolds into a flat or umbrella shape for tilting, the weight change of the soil inside the bucket triggers a hydraulic linkage again, driving the carrying bucket to move back and forth. Combined with inertia and the tilting of the bucket, this significantly improves the thoroughness of soil dumping and emptying efficiency, solving the technical problems of soil sticking to the bucket wall and incomplete dumping.

[0005] Preferably, a track is horizontally installed in the upper part of the main frame of the rack, a pre-embedded net is laid in the lower part of the main frame of the rack, a control cabinet and a fan system are installed on the side of the rack, and the control cabinet is arranged on one side of the fan system.

[0006] Preferably, a buckle is fixedly connected to the side surface of the bearing bucket; The main body of the carrying container is a frustum-shaped structure, resembling an inverted truncated cone, which facilitates the pouring of contents.

[0007] Preferably, the hoisting mechanism includes a hook, and the shaft is detachably connected to the lower end of the hook via a connector at its top.

[0008] Preferably, the tilting module further includes an end plate, which is sleeved on the end of the shaft and hinged to the support frame. Each support frame is equipped with a slide rail on one side, and a drive slider is slidably installed on each slide rail. A roller-type linear module is sleeved on the surface of the shaft. The side surface of the roller-type linear module is hinged with a plurality of transmission rods corresponding to the position of the support frame in a circular array, and the transmission rods are hinged to the drive slider. The roller-type linear module consists of several rollers driven by a servo motor that roll on the surface of the shaft, and the roller-type linear module can move up or down on the surface of the shaft.

[0009] Preferably, the balancing module further includes several caps with vent holes, each cap being fitted onto the end of a rigid tube.

[0010] Preferably, the hook passes through the adjustment groove, the carrying bucket is hooked on the hook, and the hook can slide back and forth along the long side of the adjustment groove.

[0011] Preferably, the side surface of the manifold shell is arranged in a ring array with ball joints connected and hinged to an outer pipe corresponding to the position of the rigid pipe. Each outer pipe has an inner pipe sealed at its output end, and the output end of the inner pipe is connected and hinged to the other end of the rigid pipe. The outer pipe and the inner pipe are elastically adapted by a first spring, which is sleeved on the surface of the outer pipe. The expansion and contraction of the outer and inner pipes, along with the fluid conduction, allows several rigid pipes to connect with the manifold, forming a total sealed cavity.

[0012] Preferably, the winding assembly includes several guide plates, with each pair of guide plates fixedly connected to both sides of the support frame. Each guide plate has a slidably fitted sheave housing corresponding to the position of the carrying drum on one side. Inside the sheave housing, a guide wheel is rotatably connected via a rod, and the rod on the guide wheel passes through the sheave housing. A ratchet is fixedly connected to one side of the sheave housing, and a pawl is sleeved on the end of the rod on the guide wheel, with the pawl and ratchet meshing appropriately.

[0013] Preferably, a winding drum is rotatably sleeved on the surface of the shaft, a torsion spring is sleeved inside the winding drum, and the end of the torsion spring is fixedly connected to the surface of the shaft. Several traction ropes are spirally wound on the surface of the winding drum, and the end of each traction rope passes through the groove on the guide wheel and is hooked to a buckle.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the linkage design of the tilting module and the balancing module, utilizes the weight difference of each carrying bucket to drive the hydraulic system when the support frame is gathered, so that the bucket body automatically adjusts the distance between itself and the shaft, achieving uniform distribution with the shaft as the center of gravity, effectively improving the balance and safety of hoisting, and solving the technical problems of unbalanced load-bearing at multiple lifting points and easy tipping; when the support frame is unfolded into a flat or umbrella shape for tilting, the weight change of the slag inside the bucket triggers the hydraulic linkage again, driving the carrying bucket to move back and forth. Combined with inertial force and bucket tilting, it significantly improves the thoroughness of slag dumping and emptying efficiency, solving the technical problems of slag sticking to the bucket wall and incomplete dumping.

[0015] 2. This invention uses a roller-type linear module of the tilting module to drive the support frame to precisely switch between three states: convergence, flattening, and "umbrella" shape. Combined with the traction rope and ratchet pawl mechanism of the winding assembly, it can automatically control and lock the tilting posture of the carrying bucket, effectively preventing overturning, soil falling, or collision accidents that may occur during traditional manual hooking, bucket support, and slag unloading. The hydraulic self-balancing system of the balancing module (composed of a main sealed cavity and a secondary sealed cavity, etc., made of rigid pipes, guide rods, and manifold shells) can automatically adjust the position of each carrying bucket during hoisting, ensuring that the system remains stable with the shaft as the center of gravity, greatly improving the safety of hoisting operations in deep foundation pits. It has solved the technical problems of frequent manual operation, high safety risks, and easy overturning accidents in the traditional deep foundation pit slag hoisting process.

[0016] 3. The three states of the support frame in this invention correspond to different operational requirements: the converged state is used for safe hoisting; the flat state is suitable for dumping slag containing large particles or with poor flowability, providing stable support; and the "umbrella"-shaped state is for fine slag with good flowability, enabling rapid and thorough emptying; the balancing module not only ensures hoisting balance, but its hydraulically driven reciprocating adjustment function also enhances the dumping effect; the bearing bucket maintains a stable posture and controllable direction during movement and dumping; this multi-mode design allows the device to flexibly cope with the complex composition of slag and different dumping requirements in deep foundation pit construction; it has solved the technical problems of poor adaptability, inability to effectively handle slag of different properties, and incomplete dumping of existing slag hoisting equipment.

[0017] 4. This invention features a compact structure achieved through the convergence of the support frame, facilitating rapid lowering and lifting. When unfolded into a flat or umbrella shape, it allows for the simultaneous dumping of multiple carrying containers. The unique hydraulic feedback system drives the carrying containers to reciprocate during dumping, utilizing inertial force to promote soil detachment. The umbrella shape, in particular, provides a larger tilt angle, resulting in more thorough and rapid dumping. This continuous automated operation, integrating hoisting, balancing, and dumping, avoids frequent waiting and manual intervention in traditional methods, significantly shortening the slag removal cycle.

Detailed Implementation

[0029] like Figure 1 As shown, the present invention relates to an electric hoisting and automatic dumping device for deep foundation pit excavated soil, comprising a frame 1, a hoisting mechanism 2, a dumping mechanism 3, a winding assembly 4, and a carrying bucket 5.

[0030] Specifically, such as Figures 1-3 As shown, within the main frame of the rack 1, a track 11 is horizontally installed at the top, and a pre-embedded net 12 is laid below it; the control cabinet 13 and the fan system 14 are installed on the side of the rack 1, and the control cabinet 13 is arranged on one side of the fan system 14.

[0031] The hoisting mechanism 2 consists of a lifting mechanism and a running mechanism. The lifting mechanism includes a motor, a reducer, a drum, and a hook device to realize the vertical lifting and lowering of the heavy object. The running mechanism moves the hoist horizontally along the I-beam rail 11 via an electric trolley. Both of these are existing technologies and will not be described in detail.

[0032] The side surface of the carrying bucket 5 is fixedly connected with a buckle 51; the main body of the carrying bucket 5 is a frustum-shaped structure, which is larger at the top and smaller at the bottom, and has an inverted frustum shape, which is conducive to pouring out the contents. A metal handle is installed on the top. like Figure 3 and Figure 7 As shown, the tilting mechanism 3 in this embodiment includes a tilting module 31 and a balancing module 32, as detailed below: Combination Figures 3-5 and Figures 7-9 As shown, in this embodiment, the tilting module 31 includes a shaft 311. The shaft 311 is detachably connected to the lower end of the hook via a connector (i.e., a snap ring structure) at its top, allowing the shaft 311 to be suspended along the axial direction of the hook and bear the load of the tripod support structure connected below it. An end plate 312 is sleeved on the end of the shaft 311. At least three support frames 313 are hinged in a circular array on the side surface of the end plate 312. Each support frame 313 has a slide rail 3131 installed on one side, and a drive slider 3132 is slidably installed on each slide rail 3131. A roller-type linear module 314 is sleeved on the surface of the shaft 311. The side surface of the roller-type linear module 314 is... The annular array is hinged with several transmission rods 315 corresponding to the positions of the support frame 313, and the transmission rods 315 are hinged to the drive slider 3132; in the roller linear module 314, several rollers driven by servo motors roll on the surface of the shaft 311, allowing the roller linear module 314 to move upward or downward on the surface of the shaft 311; by moving the roller linear module 314 on the surface of the shaft 311, when the roller linear module 314 moves upward, several support frames 313 can rotate axially to form a converged state; when the roller linear module 314 moves downward, several support frames 313 can rotate axially to form an unfolded state (e.g., ...). Figure 9 As shown); during the unfolding process, several support frames 313 can be laid flat on a horizontal plane (as shown). Figure 10 As shown), it can also rotate axially to form an "umbrella" shape on a flat surface (as shown). Figure 10 (As shown); when several support frames 313 are gathered together, the hoisting mechanism 2 can remove the carrying bucket 5 containing soil and slag from the deep pit; when several support frames 313 are laid flat on a horizontal plane, some soil and slag in the carrying bucket 5 are poured out, resulting in different weights for each carrying bucket 5. After adjustment by the balancing module 32, a pushing or pulling force can be applied to the carrying bucket 5 to assist in the pouring out of the soil and slag inside; when several support frames 313 are in an "umbrella" shape, it not only has the function of dumping soil and slag when several support frames 313 are laid flat on a horizontal plane, but also provides tilt support for the carrying bucket 5, so that the soil and slag inside can be poured out quickly.

[0033] This invention achieves a compact device structure through the convergence of the support frame 313, facilitating rapid lowering and lifting. When unfolded into a flat or umbrella shape, multiple carrying buckets 5 can be dumped simultaneously. The unique hydraulic feedback system drives the carrying buckets 5 to move back and forth during dumping, utilizing inertial force to promote the detachment of slag. In particular, the umbrella shape provides a larger tilt angle, making the dumping of slag more thorough and faster. This continuous automated operation, integrating hoisting, balancing, and dumping, avoids frequent waiting and manual intervention in traditional methods, significantly shortening the slag removal cycle.

[0034] Combination Figures 7-9As shown, in this embodiment, the balancing module 32 includes a manifold housing 321, which is fixedly connected to the bottom of the end plate 312. Each support frame 313 has a rigid tube 322 sleeved inside. Each rigid tube 322 has at least two adjustment slots 3221 linearly arrayed on its side surface. Each rigid tube 322 has a top cap 3222 with an air vent sleeved at its end. Each rigid tube 322 has a guide rod 323 sealed inside, corresponding to the position of the adjustment slot 3221. A secondary sealed cavity is formed between two adjacent guide rods 323 within each rigid tube 322. Each guide rod 323 has a hook 3231 fixedly connected to its side surface, and the hook 3231 passes through the adjustment slot 322. 1. The carrying bucket 5 is hung on the hook 3231, which can slide back and forth along the long side of the adjusting groove 3221. The side surface of the manifold 321 has an annular array of ball joints connected and hinged to an outer pipe 324 corresponding to the position of the rigid pipe 322. Each outer pipe 324 has an inner pipe 325 sealed at its output end, and the ball joint of the inner pipe 325 is connected and hinged to the other end of the rigid pipe 322. The outer pipe 324 and the inner pipe 325 are elastically adapted by a first spring 326, which is sleeved on the surface of the outer pipe 324. Through the expansion and contraction connection and fluid conduction between the outer pipe 324 and the inner pipe 325, several rigid pipes... 322 is connected to the manifold 321 to form a total sealed cavity; specifically, when several support frames 313 are gathered together, the carrying bucket 5 is hooked on the hook 3231. Due to the different weights of each carrying bucket 5 containing slag, the guide rod 323 corresponding to the heavier carrying bucket 5 moves within the rigid pipe 322, pushing the liquid within the rigid pipe 322 to be transported through the manifold 321 to the remaining rigid pipes 322, thereby pushing the corresponding guide rod 323 to move, realizing the automatic adjustment of the distance between the carrying bucket 5 and the shaft 311, so that the total weight of each support frame 313 and its components and the carrying bucket 5 tends to be the same, thus making the several support frames 313 evenly distributed around the shaft 311 as the center axis, in deep The system can maintain balance within the pit and be moved out of the deep foundation pit. When the support frames 313 are laid flat or in an "umbrella" shape, the bearing bucket 5 will naturally spill some soil, causing a change in the weight of the bearing buckets 5. This causes the guide rod 323 to be driven by the liquid transport in the total sealed cavity to move and adjust the bearing bucket 5. During the movement, the soil in the bearing bucket 5 is spilled out due to force and inertia, forming a reciprocating cycle. When the support frames 313 are in an "umbrella" shape, most of the bearing bucket 5 is spilled out. The liquid flow in the total sealed cavity creates a stronger negative pressure or pressure difference, causing the movement range of each bearing bucket 5 to be greater than that of the bearing bucket 5 when the support frames 313 are laid flat, and the spillage is faster.

[0035] It is worth noting that both the main sealed chamber and the secondary sealed chamber are filled with liquid, which is used to drive the guide rod 323 to move within the rigid tube 322.

[0036] In this invention, the support frame 313 has three states corresponding to different operational needs: the converged state is used for safe hoisting; the flat state is suitable for dumping slag containing large particles or with poor flowability, providing stable support; and the "umbrella"-shaped state is for fine slag with good flowability, enabling rapid and thorough emptying. The balancing module 32 not only ensures hoisting balance, but its hydraulically driven reciprocating adjustment function also enhances the dumping effect; the bearing bucket 5 maintains a stable posture and controllable direction during movement and dumping; this multi-mode design allows the device to flexibly cope with the complex composition of slag and different dumping requirements in deep foundation pit construction; it has solved the technical problems of poor adaptability, inability to effectively handle slag of different properties, and incomplete dumping of existing slag hoisting equipment.

[0037] like Figures 3-6 and Figure 10 As shown, the winding assembly 4 in this embodiment includes several guide plates 41. Each pair of guide plates 41 is fixedly connected to both sides of the support frame 313. Each guide plate 41 has a slidably fitted sheave housing 42 corresponding to the position of the carrying drum 5 on one side. Inside the sheave housing 42, a guide wheel 43 is rotatably connected via a rod. The rod on the guide wheel 43 passes through the sheave housing 42. A ratchet 44 is fixedly connected to one side of the sheave housing 42. A pawl 45 is sleeved on the end of the rod on the guide wheel 43, and the pawl 45 and the ratchet 44 mesh properly. A winding drum 46 is rotatably sleeved on the surface of the shaft 311. A torsion spring 47 is sleeved inside the winding drum 46, and the end of the torsion spring 47 is fixedly connected to the surface of the shaft 311. Several traction ropes 48 are spirally wound on the surface of the winding drum 46. The end of each traction rope 48 passes through the groove on the guide wheel 43 and is hooked to the buckle 51. When several support frames 313 are laid out flat or in an "umbrella" shape, each support frame 313 rotates axially, and the traction rope 48 pulls the end of the carrying bucket 5 to apply force. The body of the carrying bucket 5 is in contact with one side of the support frame 313, causing the carrying bucket 5 to tilt, which facilitates the dumping of the slag inside. At the same time, when several support frames 313 are laid out flat or in an "umbrella" shape, the carrying bucket 5 moves, and the traction rope 48 is tightened due to pulling the carrying bucket 5. As a result, during the movement of the carrying bucket 5, the guide wheel 43 slides on the guide plate 41, and the pawl 45 and ratchet 44 engage, so that the guide wheel 43 can only rotate in one direction or be locked. The traction rope 48 cannot retract through the guide wheel 43, so that the carrying bucket 5 always remains in an tilted state to prevent the outlet orientation of the carrying bucket 5 from changing during shaking (reciprocating movement).

[0038] This invention uses the roller-type linear module 314 of the tilting module 31 to drive the support frame 313 to precisely switch between three states: gathering, spreading, and "umbrella" shape. Combined with the traction rope 48 and ratchet pawl 45 mechanism of the winding assembly 4, it can automatically control and lock the tilting posture of the carrying bucket 5, effectively preventing overturning, soil falling, or collision accidents that may occur during traditional manual hooking 3231, bucket lifting, and slag unloading. The hydraulic self-balancing system of the balancing module 32 (composed of a main sealed cavity and a secondary sealed cavity, including rigid pipe 322, guide rod 323, and manifold shell 321) can automatically adjust the position of each carrying bucket 5 during hoisting, so that the system always remains stable with the shaft 311 as the center of gravity, greatly improving the safety of hoisting operations in deep foundation pits. It has solved the technical problems of frequent manual operation, high safety risks, and easy overturning accidents in the traditional deep foundation pit slag hoisting process.

[0039] Working principle: This embodiment provides an electric hoisting and automatic dumping device for deep foundation pit slag. During installation, the frame 1 is first installed on the ground, and then the soil is covered on the pre-buried net 12 to make the device firmly installed on the ground. Then, the lifting mechanism in the hoisting mechanism 2 moves the hook carrying the shaft 311 and support frame 313 and other components down into the pit. Several support frames 313 are gathered together (such as) Figure 9 As shown): The external circuit mechanism enables the roller linear module 314 to work. The roller driven by the servo motor rolls on the surface of the shaft 311, driving the transmission rod 315 to rotate axially and applying tension to several support frames 313 hinged to the end plate 312, causing the support frames 313 to converge. Then, the load-bearing bucket 5 is hung on the hook 3231, and the end of the traction rope 48 is hung on the buckle 51. At this time, due to the difference in the weight of the slag in each load-bearing bucket 5, the heavier bucket will apply pressure to the liquid in the rigid pipe 322 where it is located through the hook 3231 and the guide rod 323. The pressurized liquid automatically flows to the rigid pipe 322 with lower pressure through the manifold 321, pushing the corresponding guide rod 323 to move, dynamically adjusting the distance between each load-bearing bucket 5 and the center of the shaft 311, realizing automatic torque balance, so that all support frames 313 and load-bearing buckets 5 are evenly distributed with the shaft 311 as the axis, ensuring the stability of the hoisting process. Several support frames 313 are laid out flat and in an "umbrella" shape: When the carrying bucket 5 is moved out of the pit by the lifting mechanism of the hoisting mechanism 2, the running mechanism in the hoisting mechanism 2 moves on the track 11, causing the carrying bucket 5 to move out of the pit opening. At this time, the external circuit mechanism first activates the roller linear module 314, which drives the rollers to move on the shaft 311 via the servo motor. Then, the transmission rod 315 drives the several support frames 313 to unfold, achieving a flat state. Furthermore, the support frames 313 are axially... During rotation, the guide wheel 43 rotates in a non-meshing sliding state through the ratchet 44 and pawl 45. The traction rope 48 pulls the end of the carrying bucket 5, causing the bucket body of the carrying bucket 5 to completely adhere to one side of the support frame 313 and tilt. At this time, each support frame 313 is in a horizontal state, and some soil in the carrying bucket 5 is poured out, causing the weight of each carrying bucket 5 to change. The initial position of the guide rod 323 in the rigid tube 322 is moved by the hydraulic change of the manifold 321, driving the carrying bucket 5 to move back and forth. During the movement, the slag is further dumped due to force and inertia. On the basis of the flat state, the roller linear module 314 continues to move downward, driving the support frame 313 to rotate further axially and unfold in an "umbrella" shape. At this time, the support frame 313 forms a certain angle with the horizontal plane, and the tilt angle of the carrying bucket 5 is larger. The slag is dumped out quickly and in large quantities under the action of gravity. In the umbrella state, most of the slag in the carrying bucket 5 is dumped out, and the liquid flow in the total sealed cavity forms a stronger negative pressure or pressure difference, which makes the movement range of each carrying bucket 5 larger than in the flat state and the dumping speed faster. At the same time, the traction rope 48 is kept taut during the movement of the carrying bucket 5. The guide wheel 43 and the ratchet mechanism ensure that the carrying bucket 5 is always in the preset tilt posture, preventing the slag from spilling or the outlet direction from shifting due to shaking during the dumping process. The umbrella state is suitable for dumping soil with good fluidity. Through the reciprocating movement with a large tilt angle and a large stroke, the slag is dumped quickly and thoroughly, which greatly improves the work efficiency.

[0040] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
