Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, specifically relating to an integrated device for feeding, leveling, and discharging materials into a flat warehouse. Background Technology

[0002] Flat warehouses are widely used in grain storage and logistics due to their simple structure, low construction cost, and large storage capacity. However, with the development of the grain storage industry, higher demands are being placed on the efficiency and automation of flat warehouse loading and unloading operations. Traditional loading and unloading operations mainly rely on manual operation and simple machinery, which has many problems: high labor intensity, low efficiency, and difficulty in meeting the needs of large-scale grain loading and unloading; moreover, traditional flattening methods cannot guarantee a flat surface for grain piles, failing to fully utilize warehouse capacity; and there are high safety risks, as equipment is easily buried by grain piles, leading to malfunctions and safety accidents, affecting the continuity and safety of operations.

[0003] Currently available grain distribution equipment for flat warehouses, while capable of leveling materials upon entry and exit, suffers from the following problems:

[0004] (1) The current grain distribution equipment has no other fixing except for the flexible positioning of the steel wire rope. It relies solely on the equipment's own weight to hang down naturally to stabilize the equipment. During the process of entering and leaving the warehouse, the reaction force of the material will cause the equipment to shake, making it impossible to stabilize the material leveling and exiting the warehouse.

[0005] (2) These devices rely on their own weight to exert pressure on the material to scrape it, and the equipment has poor discharge effect when encountering caking material.

[0006] (3) The equipment is at risk of being buried by grain piles. Once buried, the equipment has poor self-rescue ability and is prone to failure. Utility Model Content

[0007] This utility model provides an integrated feeding, leveling, and discharging device for flat warehouses, aiming to solve the problems of current grain distribution equipment relying solely on its own weight for stability, resulting in poor material leveling, poor discharging performance, and poor self-rescue capability after the equipment is buried.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an integrated device for feeding, leveling, and discharging materials into a flat warehouse, comprising:

[0009] A traveling truss is erected on the upper part of the bungalow and is able to move laterally within the bungalow.

[0010] A supporting vertical beam is mounted on the traveling truss at its upper end and suspended at its lower end; the supporting vertical beam moves laterally with the traveling truss.

[0011] A lifting mechanism is installed on the supporting vertical beam and moves along the vertical direction of the supporting vertical beam;

[0012] A material handling mechanism is cantilevered and connected to the lifting mechanism, and moves up and down with the lifting mechanism; and

[0013] A telescopic connection mechanism is rigidly supported between the traveling truss and the material handling mechanism; the reaction force of the material handling mechanism is transmitted to the traveling truss through the telescopic connection mechanism (3) so that the material handling mechanism and the traveling truss move synchronously.

[0014] In one possible implementation, the retractable connection mechanism includes a plurality of rotatably connected folding arms, the upper end of which is rotatably connected to the traveling truss, and the lower end of which is rotatably connected to the material handling mechanism; the folding arms are folded as the material handling mechanism rises and unfolded as the material handling mechanism (4) descends.

[0015] In one possible implementation, a hoisting mechanism is also included, which is mounted on the traveling truss, and the hoisting mechanism’s winding rope is connected to the articulated arm or the material handling mechanism.

[0016] The winding or rewinding of the hoisting mechanism causes the material handling mechanism to tilt downwards or upwards.

[0017] When the lifting mechanism moves the material handling mechanism closer to or away from the material in the flat warehouse, the hoisting mechanism simultaneously unfolds or retracts.

[0018] The folding arm unfolds or folds when the hoisting mechanism unfolds or rewinds.

[0019] In one possible implementation, the material handling mechanism includes a cantilever, a chain drive assembly mounted on the cantilever, and a scraper mounted on the chain drive assembly; the telescopic connection mechanism is connected to the cantilever.

[0020] In one possible implementation, the lifting mechanism is symmetrically provided with mounting plates along the lateral movement direction, and both ends of the first shaft are respectively mounted on the mounting plates; the drive sprocket in the chain drive assembly is mounted on the first shaft.

[0021] In one possible implementation, the outer side of the mounting plate is provided with a tension adjustment assembly for adjusting the chain tension in the chain drive assembly; the tension adjustment assembly includes a fixed plate, a movable plate, an adjusting screw, and a locking nut; the fixed plate is fixed to the outer side of the mounting plate, the movable plate is fitted onto the first shaft, the adjusting screw is installed between the fixed plate and the movable plate, and is locked by multiple locking nuts; the mounting plate is provided with an elongated hole for the first shaft to pass through; when the chain is slack, the adjusting screw and locking nuts drive the movable plate and the first shaft to move to tighten the chain.

[0022] In one possible implementation, the lower end of the retractable connecting mechanism is rotatably connected to the side of the material handling mechanism away from the supporting vertical beam.

[0023] In one possible implementation, the traveling truss is provided with a mounting base, and the upper end of the telescopic connecting mechanism is connected to the mounting base.

[0024] In one possible implementation, the lifting mechanism includes a lifting drive device, a vehicle body, and a limiting wheel mounted on the vehicle body. The supporting vertical beam is provided with a slide rail extending in the vertical direction, and the limiting wheel rolls up and down along the slide rail. The lifting drive device drives the vehicle body to move up and down. The material handling mechanism is rotatably connected to the vehicle body.

[0025] In one possible implementation, the traveling truss includes a horizontal track mounted on the upper part of the bungalow, a traveling trolley that moves laterally along the horizontal track, and a transverse main beam, with both ends of the transverse main beam mounted on the traveling trolley and a supporting vertical beam mounted on one end of the transverse main beam.

[0026] The integrated feeding, leveling, and discharging device for flat warehouses provided by this utility model has the following advantages compared with the prior art:

[0027] (1) This application achieves stable operation of the entire device through rigid connection and force path optimization: a telescopic connection mechanism is set between the material handling mechanism and the traveling truss. The material handling mechanism is rigidly connected to the stable traveling truss through the telescopic connection mechanism. The reaction force of the material handling mechanism as it moves laterally with the traveling truss can be transmitted to the traveling truss through the telescopic connection mechanism, reducing the impact of the reaction force on the material handling mechanism and ensuring that the material handling mechanism can always maintain a relatively fixed posture with the traveling truss. This forces the material handling mechanism to move synchronously with the traveling truss, thereby avoiding the problem of the material handling mechanism lagging behind the traveling truss and swaying unstablely when moving laterally, and improving the stability of the material handling mechanism during material leveling and discharge. The smooth movement of the material handling mechanism also reduces the problem of the material handling mechanism being transmitted to the supporting vertical beam when it is subjected to the reaction force of the material, causing the supporting vertical beam to sway, thus improving the stability of the entire device during material feeding, leveling and discharge.

[0028] (2) Stability of the quadrilateral structure: Through the connection between the supporting vertical beam and the traveling truss, the connection between the material handling mechanism and the supporting vertical beam, and the connection between the telescopic connection mechanism and the traveling truss, a quadrilateral structure based on the traveling truss is formed. These four parts are connected in sequence and mutually restrict each other. When the traveling truss moves laterally, it can drive the parts in the quadrilateral structure to move synchronously, thereby improving the stability of the entire device in feeding, leveling and discharging.

[0029] (3) Versatility of leveling and unloading at different stacking heights: The lifting mechanism drives the material handling mechanism to move up and down along the supporting vertical beam, adjusting the vertical distance between the material handling mechanism and the material, so that the material handling mechanism can achieve the optimal leveling and unloading height, thereby ensuring the smooth and efficient leveling and unloading process. When the material handling mechanism moves up and down to adjust the height, the telescopic connection mechanism can extend or shorten to adapt to the height adjustment of the material handling mechanism.

[0030] (4) It has the effect of breaking up hardened materials: The telescopic connection mechanism is connected between the material handling mechanism and the traveling truss. The traveling truss is supported in the flat warehouse as a rigid component and has a certain height. The telescopic connection mechanism has a downward force on the material handling mechanism by relying on the traveling truss. Moreover, the gravity of the telescopic connection mechanism can also be applied to the material handling mechanism. Therefore, when the material handling mechanism encounters hardened materials, the reaction force of the hardened materials on the material handling mechanism cannot be offset by the power of the material handling mechanism during movement and the gravity borne by the material handling mechanism. Therefore, the material handling mechanism can break up the hardened materials, thereby improving the material discharge effect and the feeding and leveling effect.

[0031] (5) It has the ability to rescue itself when buried by materials: When the material handling mechanism is buried in materials, it can be moved upward by the lifting mechanism and the telescopic connection mechanism to pull the material handling mechanism out of the materials, thereby avoiding the problem that the materials stick to the chain and sprocket of the material handling mechanism, causing the material handling mechanism to jam and fail to rotate normally to perform the flat material discharge operation.

[0040] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] Before demonstrating the specific embodiments of this application, it is necessary to explain the flat warehouse in order to gain a deeper understanding of the technical solution and the effects that can be achieved. Flat warehouses have a large effective area and load capacity. The standard dimensions of tall flat warehouses are usually a span of 21m to 30m, a length of 60m, and a grain stacking height of not less than 6m. Due to the large span and long length of flat warehouses, the suspended material handling mechanism will experience significant disturbance and swaying caused by the reaction force of the material when moving laterally.

[0042] Please refer to the following: Figures 1 to 6 The present invention will now describe the integrated feeding, leveling, and discharging device for flat warehouses. The integrated feeding, leveling, and discharging device for flat warehouses includes: a traveling truss 1, a supporting vertical beam 8, a lifting mechanism 7, and a telescopic connecting mechanism 3.

[0043] The traveling truss 1 is erected on the upper part of the flat warehouse and can move laterally within the warehouse. Specifically, regarding the installation of the traveling truss 1, multiple columns can be symmetrically arranged on two opposite inner sides inside the flat warehouse, and the traveling truss 1 is installed on the columns. The installation method of the traveling truss 1 is the conventional installation method in flat warehouses for large factories or grain storage. The structure, function, and role of the traveling truss 1 are equivalent to the overhead crane installed in a large factory, and will not be described in detail in this embodiment.

[0044] The upper end of the support vertical beam 8 is mounted on the traveling truss 1, and the lower end is suspended. The support vertical beam 8 moves laterally with the traveling truss 1. Only one support vertical beam 8 is provided, with the lower end not fixed and the upper end fixed. The support vertical beam 8 provides support for the lifting mechanism 7 and also for the material handling mechanism 4.

[0045] The lifting mechanism 7 is installed on the support beam 8 and moves up and down along the support beam 8. The function of the lifting mechanism 7 is to drive the material handling mechanism 4 to move up and down, and adjust the distance between the material handling mechanism 4 and the material, thereby ensuring the leveling and unloading effect.

[0046] The material handling mechanism 4 is cantilevered and mounted on the lifting mechanism 7. The material handling mechanism 4 is connected to the lifting mechanism 7 via a first shaft 46 and moves up and down with the lifting mechanism 7. The material handling mechanism 4 is used for leveling or unloading materials. Located below the traveling truss 1, it moves up and down under the action of the lifting mechanism 7. Due to the connection between the material handling mechanism 4 and the lifting mechanism 7, the material handling mechanism 4 can also tilt upwards or downwards under the unfolding and rewinding of the hoisting mechanism 2 to adapt to the needs of material adjustment. When the material handling mechanism 4 moves upwards, it is achieved through the cooperation of the hoisting mechanism 2 and the lifting mechanism 7.

[0047] The telescopic connection mechanism 3 is rigidly supported between the traveling truss 1 and the material handling mechanism 4; the reaction force on the material handling mechanism 4 is transmitted to the traveling truss 1 through the telescopic connection mechanism 3 so that the material handling mechanism 4 and the traveling truss 1 move synchronously.

[0048] The lifting mechanism 7 moves the material handling mechanism 4 closer to or further away from the materials in the flat warehouse, adjusting the height of the material handling mechanism 4. The telescopic connecting mechanism 3 extends or shortens synchronously, always providing rigid support for the material handling mechanism 4.

[0049] The integrated feeding, leveling, and discharging device for flat warehouses provided by this utility model has the following advantages compared with the prior art:

[0050] (1) This application achieves stable operation of the entire device through rigid connection and force path optimization: a telescopic connection mechanism 3 is set between the material handling mechanism 4 and the traveling truss 1. The material handling mechanism 4 is rigidly connected to the stable traveling truss 1 through the telescopic connection mechanism 3. The reaction force of the material handling mechanism 4 as it moves laterally with the traveling truss 1 can be transmitted to the traveling truss 1 through the telescopic connection mechanism 3, reducing the impact of the reaction force on the material handling mechanism 4 and ensuring that the material handling mechanism 4 can always maintain a relatively fixed posture with the traveling truss 1. This forces the material handling mechanism 4 to move synchronously with the traveling truss 1, thereby avoiding the problem of the material handling mechanism 4 lagging behind the traveling truss 1 and swaying unstablely when moving laterally, and improving the stability of the material handling mechanism 4 during material leveling and discharge. The smooth movement of the material handling mechanism 4 also reduces the problem of the material handling mechanism 4 being transmitted to the supporting vertical beam 8 when it is subjected to the reaction force of the material, causing the supporting vertical beam 8 to sway, thus improving the stability of the entire device during material feeding, leveling and discharge.

[0051] (2) Stability of the quadrilateral structure: Through the connection between the supporting vertical beam 8 and the traveling truss 1, the connection between the material handling mechanism 4 and the supporting vertical beam 8, and the connection between the telescopic connection mechanism 3 and the material handling mechanism 4 and the traveling truss 1, a quadrilateral structure based on the traveling truss 1 is formed. These four parts are connected in sequence and mutually restrict each other. When the traveling truss 1 moves laterally, it can drive the parts in the quadrilateral structure to move synchronously, thereby improving the stability of the entire device in feeding, leveling and discharging.

[0052] (3) Versatility of leveling and unloading at different stacking heights: The lifting mechanism 7 drives the material handling mechanism 4 to move up and down along the supporting vertical beam 8, adjusting the vertical distance between the material handling mechanism 4 and the material, so that the material handling mechanism 4 reaches the optimal leveling and unloading height, thereby ensuring the smooth and efficient leveling and unloading process. When the material handling mechanism 4 moves up and down to adjust its height, the telescopic connecting mechanism 3 can extend or shorten to adapt to the height adjustment of the material handling mechanism 4. When the telescopic connecting mechanism 3 moves upward, the lifting mechanism 7 and the hoisting lifting mechanism 2 work together to lift the material handling mechanism 4 upward from two points, ensuring the smoothness of the overall upward movement of the material handling mechanism 4.

[0053] (4) It has the effect of breaking up hardened materials: The telescopic connecting mechanism 3 is connected between the material handling mechanism 4 and the traveling truss 1. The traveling truss 1 is supported in the flat warehouse as a rigid component and has a certain height. The telescopic connecting mechanism 3 has a downward force on the material handling mechanism 4 by relying on the traveling truss 1. Moreover, the gravity of the telescopic connecting mechanism 3 can also be applied to the material handling mechanism 4. Therefore, when the material handling mechanism 4 encounters hardened materials, the reaction force of the hardened materials on the material handling mechanism 4 cannot withstand the power of the material handling mechanism 4 during movement and the gravity borne by the material handling mechanism 4. Therefore, the material handling mechanism 4 can break up the hardened materials, thereby improving the material discharge effect and the feeding and leveling effect.

[0054] (5) It has the ability to rescue itself when buried by materials: When the material handling mechanism 4 is buried in materials, the material handling mechanism 4 is pulled out of the materials by the upward movement of the lifting mechanism 7 and the telescopic connection mechanism, thereby avoiding the material from sticking to the chain 42 and sprocket of the material handling mechanism 4, causing the material handling mechanism 4 to jam and fail to rotate normally to perform the flat material discharge operation.

[0055] Combination Figure 3 As shown, the telescopic connection mechanism 3 includes multiple rotatably connected folding arms. The upper end of the folding arm is rotatably connected to the traveling truss 1, and the lower end of the folding arm is rotatably connected to the material handling mechanism 4. The folding arm is folded as the material handling mechanism 4 rises and unfolded as the material handling mechanism 4 falls.

[0056] The upper and lower ends of the folding arm refer to the two free ends of multiple folding arms that are rotatably connected. Since the angle of the folding arm needs to change when it is in different states, both the upper and lower ends of the folding arm are rotatably connected so that the angle can be adjusted at any time according to the different lifting heights of the material handling mechanism.

[0057] Specifically, the multiple folding arms include a first arm 31 and a second arm 32 that are rotatably connected end to end. The lower end of the first arm 31 is rotatably connected to the upper end of the second arm 32, the upper end of the first arm 31 is rotatably connected to the traveling truss 1, and the lower end of the second arm 32 is rotatably connected to the material handling mechanism 4. The V-shaped angle formed by the first arm 31 and the second arm 32 decreases as the material handling mechanism 4 rises and increases as the material handling mechanism 4 falls.

[0058] The telescopic connection mechanism 3 provided in this embodiment is a linkage telescopic structure. Compared with the soft connection of the winding rope 21 of the hoisting mechanism 2, this structure is a rigid connection. The material handling mechanism 4 can move synchronously with the traveling truss 1 through the telescopic connection mechanism 3, thereby avoiding the risk of the material handling mechanism 4 swinging or shaking due to the lateral reaction force of the material, which would cause the entire device to be unstable. On the positive side, the telescopic connection mechanism 3 can ensure that the material handling mechanism 4 can still maintain the stability of the equipment after being subjected to lateral force, and ensure the stability of feeding, leveling and discharging.

[0059] Since this linkage telescopic structure only unfolds or folds with the lifting mechanism, although it has the function of transmitting force, it cannot assist in lifting the material handling mechanism. Therefore, the linkage telescopic structure is used in conjunction with the winch lifting mechanism 2. The winch lifting mechanism 2 can be used in conjunction with the lifting mechanism to lift the material handling mechanism, thereby improving the stability of the material handling mechanism during lifting.

[0060] Further, see Figure 3 A hinge support 33 is provided at the connection end between the first arm 31 and the second arm 32. The second arm 32 is rotatably connected to the hinge support 33 via a second shaft, and the first arm 31 is rotatably connected to the hinge support 33 via a third shaft. This application improves the firmness and reliability of the connection between the first arm 31 and the second arm 32 by providing a hinge support 33 between them.

[0061] The retractable connection mechanism 3 provided in this application can take many forms.

[0062] For example, the telescopic connection mechanism 3 can be replaced by a telescopic mechanism such as a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod, to achieve a rigid connection between the material handling mechanism 4 and the traveling truss 1, and to achieve height adjustment of the material handling mechanism 4. In this case, the telescopic connection mechanism has an active telescopic function, and there is no need to configure a hoisting mechanism 2.

[0063] When the telescopic connecting mechanism 3 is a telescopic cylinder, the cylinder body is fixed to the traveling truss 1, while the cylinder rod is rotatably connected to the material handling mechanism 4. This is to allow the material handling mechanism 4 to tilt upwards or downwards under the drive of the telescopic connecting mechanism 3, while the lifting mechanism 7 remains stationary. In this case, the telescopic connecting mechanism 3 is rotatably connected to the lifting mechanism 7 via the first shaft 46.

[0064] It should be noted that when the telescopic connection mechanism is used only as a rigid force transmission mechanism, its lower end can also be fixedly connected to the material handling mechanism.

[0065] The device provided in this application also includes a winch lifting mechanism 2, which is mounted on the traveling truss 1. The winch lifting mechanism 2's winding rope 21 is connected to the articulated boom or material handling mechanism 4. The material handling mechanism 4 is rotatably connected to the lifting mechanism 7 via a first shaft 46. The winding rope 21 of the winch lifting mechanism 2 unfolds or rewinds, causing the material handling mechanism 4 to tilt downwards or upwards. In this case, since the articulated boom does not have an active lifting function, the active lifting function of the winch lifting mechanism 2 can assist the material handling mechanism 4 to rise rapidly to achieve height adjustment.

[0066] The hoisting lifting mechanism 2 is installed on the traveling truss 1. The function of the hoisting lifting mechanism 2 is to lift the material handling mechanism 4. At the same time, the hoisting rope 21 is lowered as the lifting mechanism 7 descends, and the hoisting mechanism 4 is always lifted. The hoisting rope 21 of the hoisting lifting mechanism 2 can be directly installed on the material handling mechanism 4. By lifting the material handling mechanism 4, the telescopic connecting mechanism 3 can be retracted. Alternatively, the hoisting rope 21 of the hoisting lifting mechanism 2 can be directly installed on the telescopic connecting mechanism 3. The telescopic connecting mechanism 3 can drive the material handling mechanism 4 to be lifted.

[0067] When the lifting mechanism 7 moves the material handling mechanism 4 closer to or further away from the material in the flat warehouse, the hoisting mechanism 2 simultaneously unfolds or retracts; in this case, when the lifting mechanism moves the material handling mechanism 4 up and down, the hoisting mechanism 2, as an auxiliary, also simultaneously retracts or releases the rope.

[0068] The folding arm unfolds or folds when the hoisting mechanism 2 unfolds or retracts; in this case, the folding arm unfolds or folds as the hoisting mechanism 2 and the lifting mechanism 7 rise and fall.

[0069] The material handling mechanism 4 features an adaptive tilt adjustment function achieved through a winch lifting mechanism in conjunction with a folding arm structure. When the lifting mechanism 7 is stationary, the winch lifting mechanism 2 can unwind the winding rope 21, causing the material handling mechanism 4 to tilt downwards under its own weight. Alternatively, when the winding rope 21 is wound up, it pulls the material handling mechanism 4 upwards, thus meeting the requirements for adjusting the angle of the scraper 43 during material leveling and discharge, thereby improving the leveling and discharge efficiency. By adjusting the tilt angle of the material handling mechanism 4 through the winch lifting mechanism 2 in conjunction with the lifting mechanism 7, the scraper 43 conveying component is made to conform to the material, ensuring the stability of the device during material leveling and discharge.

[0070] Therefore, when the hoisting mechanism 2 provided in this application is used in conjunction with a folding arm that does not have an active lifting adjustment function, the lower end of the folding arm is rotatably connected to the material handling mechanism 4, and the upper end is rotatably connected to the traveling truss 1. The hoisting mechanism 2 can serve as the power source for the folding arm to unfold or retract. The winding rope 21 of the hoisting mechanism 2 is connected to the folding arm or the material handling mechanism 4. When the lifting mechanism 7 moves upward, it drives the material handling mechanism 4 to move upward, and also drives the folding arm to retract and shorten. When the lifting mechanism 7 moves downward, it drives the material handling mechanism 4 to move downward, and also drives the folding arm to unfold and extend. The unfolding or rewinding of the hoisting mechanism 2 causes the material handling mechanism 4 to tilt downward or upward around the first axis 46.

[0071] In some embodiments, see Figure 1 As shown, the material handling mechanism 4 includes a cantilever frame 41, a chain drive assembly mounted on the cantilever frame 41, and a scraper 43 mounted on the chain drive assembly; the telescopic connection mechanism 3 is connected to the cantilever frame 41.

[0072] The coiled rope 21 can be optionally connected to the cantilever 41 (in this application). Figure 1 The diagram shown illustrates the connection of the lower end of the coiled rope 21 to the cantilever frame 41. The lower end of the coiled rope 21 can be locked to the cantilever frame 41 using a rope clamp.

[0073] In this application, the cantilever 41 is connected to the lifting mechanism 7 via the first shaft 46. The cantilever 41 is welded from structural steel to form a frame structure. The chain drive assembly is installed on the cantilever 41. The chain drive assembly includes a drive sprocket, a driven sprocket 44, and a chain drive motor 47. The chain drive motor 47 is installed on the outside of the cantilever 41. The drive sprocket is installed on the first shaft 46 and shares the first shaft 46 with the cantilever 41. The driven sprocket 44 is installed at the end of the cantilever 41 away from the lifting mechanism 7 via the fourth shaft 45. Space is provided inside the cantilever 41 for the rotation of the chain 42.

[0074] Two drive sprockets are installed on the first shaft 46, and two driven sprockets 44 are installed on the fourth shaft 45, which work together to wind two chains 42. Scrapers 43 are evenly arranged around the chains 42, and the two ends of the scrapers 43 are fixed on the two chains 42. They scrape the material as the chains 42 rotate, thus achieving material leveling and discharge.

[0075] In some embodiments, see Figure 1 and Figure 2 The lifting mechanism 7 is symmetrically provided with mounting plates 6 along the lateral movement direction, and both ends of the first shaft 46 are respectively mounted on the mounting plates 6; the drive sprocket in the chain drive assembly is mounted on the first shaft 46. In this embodiment, the mounting plates 6 provide mounting support for the chain drive assembly.

[0076] In some embodiments, see Figure 2 The outer side of the mounting plate 6 is provided with a tension adjustment component 5 for adjusting the tension of the chain 42 in the chain drive assembly. The tension adjustment component 5 includes a fixed plate 51, a movable plate 54, an adjusting screw 52, ​​and a locking nut 53. The fixed plate 51 is fixed to the outer side of the mounting plate 6, the movable plate 54 is fitted onto the first shaft 46, and the adjusting screw 52 is installed between the fixed plate 51 and the movable plate 54 and locked by multiple locking nuts 53. The mounting plate 6 is provided with an elongated hole for the first shaft 46 to pass through. When the chain 42 is slack, the adjusting screw 52 and the locking nut 53 drive the movable plate 54 and the first shaft 46 to move to tighten the chain 42.

[0077] During long-term rotational transmission, both chain 42 and sprocket inevitably wear down. After wear, chain 42 loosens, and the increased pitch leads to misalignment with the sprocket, causing tooth skipping and chain slippage, directly affecting transmission accuracy and stability. Therefore, chain 42 needs timely adjustment after wear to extend the service life of the chain drive assembly. Furthermore, the tension of chain 42 also needs to be adjusted during initial installation to ensure optimal transmission performance.

[0078] Therefore, this application provides tension adjustment components 5 on the outer sides of both mounting plates 6, and adjusts the tension of the chain 42 through the elongated holes provided on the mounting plates 6.

[0079] The tension adjustment assembly 5 includes multiple locking nuts 53 used in conjunction. Supports are provided on both the fixed plate 51 and the movable plate 54. The supports are provided with through holes through which the adjusting screw 52 passes. Locking nuts 53 are used to lock the adjusting screw 52 on both sides of the support. When the chain 42 is slack, the locking nuts 53 are loosened first. The adjusting screw 52 drives the movable plate 54 and the first shaft 46 to move and tighten the chain 42. Then the locking nuts 53 are locked.

[0080] At the free end of the cantilever 41, a tension adjustment component 5 is also provided corresponding to the driven sprocket 44.

[0081] Alternatively, the material handling mechanism 4 can also be another handling method such as a screw conveyor.

[0082] In some embodiments, see Figure 1 The lower end of the telescopic connecting mechanism 3 rotates the material handling mechanism 4 away from the supporting vertical beam 8. That is, the telescopic connecting mechanism 3 acts as a rigid support, resting on the suspended end of the material handling mechanism 4, particularly by eccentrically connecting the material handling mechanism. This ensures that the center of gravity of the material handling mechanism is between the telescopic connecting mechanism 3 and the supporting vertical beam 8, providing stable support and ensuring the synchronization of the material handling mechanism's movement with the traveling truss 1. The hoisting mechanism 2 is also eccentrically installed on the side of the traveling truss 1 away from the supporting vertical beam 8.

[0083] Explained, the lifting point of the hoisting mechanism 2 for the material handling mechanism 4 is far away from the connection point between the material handling mechanism 4 and the supporting vertical beam 8, so that the lifting point and the connection point are located on opposite sides of the center of the material handling mechanism 4. This arrangement can improve the balance of the suspended end of the material handling mechanism 4, prevent the material handling mechanism 4 from swinging or shaking when it moves, and improve the stability of the device during use.

[0084] In some embodiments, see Figure 3 The traveling truss 1 is equipped with a mounting base 34, and the upper end of the telescopic connecting mechanism 3 is connected to the mounting base 34. Different telescopic connecting mechanisms 3 use fixed or rotating connections, as analyzed above, and will not be repeated here. If a hoisting mechanism 2 is provided, the hoisting mechanism 2 is also mounted on the mounting base 34.

[0085] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The lifting mechanism 7 includes a lifting drive device, a vehicle body 71, and a limiting wheel 72 mounted on the vehicle body 71. A slide rail (not shown in the figure) extending in the vertical direction is provided on the support vertical beam 8. The limiting wheel 72 rolls up and down along the slide rail. The lifting drive device drives the vehicle body 71 to move up and down. The material handling mechanism 4 is rotatably connected to the vehicle body 71.

[0086] Optionally, the lifting drive device includes a lifting drive motor, a drive gear connected to the lifting drive motor, and a rack (not shown in the figure) fixed vertically on the support beam 8. The vehicle body 71 is connected to the gear via a shaft. The lifting drive motor drives the shaft to rotate, which in turn drives the gear to rotate along the rack, thereby realizing the lifting of the lifting mechanism 7. The limiting wheel 72 serves as a guide and limiter, ensuring that the vehicle body 71 moves vertically without the risk of deviation. A guide beam 81 that cooperates with the limiting wheel 72 is provided on the support beam 8. The guide beam 81 is provided with a slide rail to prevent the limiting wheel 72 from deviating. Alternatively, the limiting wheel 72 may be provided with a stop in the axial direction, which can also prevent the limiting wheel 72 from deviating from the guide beam 81. In this case, the guide beam 81 does not need to be provided with a slide rail.

[0087] Optionally, the lifting drive device is an electric sliding table structure or a worm gear lifting structure.

[0088] The supporting vertical beam 8 is also a frame structure, made of welded steel. The supporting vertical beam 8 has a channel for the lifting mechanism 7 to rise and fall. At the same time, there are four limiting wheels 72, which guide and limit the lifting mechanism 7 from two opposite directions, limiting the vehicle body 71 within the supporting vertical beam 8, ensuring that the vehicle body 71 will not deviate when moving up and down.

[0089] Specifically, the mounting plate 6 is fixed to the vehicle body 71, and the suspension bracket of the material handling mechanism 4 is mounted on the mounting plate 6.

[0090] In some embodiments, see Figure 1 , Figure 4 and Figure 5 The traveling truss 1 includes a horizontal track 13 installed on the upper part of the flat warehouse, a traveling trolley 12 that moves laterally along the horizontal track 13, and a transverse main beam 11. Both ends of the transverse main beam 11 are installed on the traveling trolley 12; a supporting vertical beam 8 is installed on one end of the transverse main beam 11; and the hoisting mechanism 2 is also installed on the transverse main beam 11.

[0091] The hoisting mechanism 2 can be an electric hoist or a winch; and the entire traveling truss 1, including the hoisting mechanism 2, is similar to a crane, and the specific structure and working principle will not be described in detail.

[0092] The device provided in this application, in conjunction with an electrical system, integrates control, communication, and detection modules, enabling intelligent control and monitoring of material leveling and unloading, achieving fully automated and intelligent operation, improving the reliability and safety of device operation, enabling continuous operation, and increasing the efficiency of material leveling and unloading.

[0093] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0094] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
