Description

Technical Field

[0001] This disclosure relates to the field of transport vehicle technology, specifically to an automatic loading and unloading unit and an automatic loading and unloading container. Background Technology

[0002] In existing technologies, cargo boxes are commonly used to hold corrosive materials such as household waste. These materials are supported on slats, and automatic unloading is achieved through the reciprocating motion of the slats. The slats are driven by a power unit, and the slats and power unit are typically connected by welding. However, due to the relatively small cross-sectional area of ​​the slats, the structural strength at the weld points is low, making the connections prone to detachment. Once detachment occurs, it not only interrupts normal unloading operations but also involves a complex repair process. Even after repair, the probability of detachment recurring is still high. Furthermore, insufficient connection strength can lead to uneven stress on the slats during transmission, which can easily cause tearing or deformation of the slats, significantly shortening their service life.

[0031] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0032] This disclosure relates to an automatic loading and unloading unit, which can be applied to various transport vehicles, semi-trailers, and engineering dump trucks that require efficient and automated loading and unloading of goods. The truck body is typically used to transport various materials, including corrosive materials such as household waste. The automatic loading and unloading unit is installed inside the truck body and near the front of the truck body to expand the material carrying space. The automatic loading and unloading unit includes a conveying device and a driving device. The conveying device includes multiple fixed plates and movable plates fixed to the bottom of the truck body and extending along the length of the truck body. The fixed plates are spaced apart along the width of the truck body. The two sides of the movable plates in the width direction are respectively guided and engaged with two adjacent fixed plates and can be relatively displaced with the adjacent fixed plates. The material carried on the movable plate moves with the movable plate towards the outlet.

[0033] The drive unit includes a drive unit and a transmission unit. The transmission unit, controlled by the drive unit, drives a movable plate to reciprocate relative to a fixed plate along the length of the vehicle body. To enhance the connection strength between the transmission unit and the movable plate, a first connecting plate is provided at the bottom of the movable plate. The transmission unit is configured to extend along the length of the movable plate, and a second connecting plate is provided at its top. The connection structure between the transmission unit and the movable plate is arranged sequentially from bottom to top in the height direction, consisting of the first connecting plate, the movable plate, the transmission unit, and the second connecting plate. These connection structures are fixed with bolts, thereby enhancing the stability between the drive unit and the transmission device inside the automatic loading and unloading unit. This reduces the problem of tearing or deformation of the movable plate caused by uneven force during transmission due to insufficient connection strength between the transmission unit and the movable plate, and extends the service life of the movable plate.

[0034] The automatic loading and unloading unit disclosed herein effectively enhances the structural strength and stability of the overall connection by adding a first connecting plate and a second connecting plate to the drive device and clamping and fixing the movable plate and the transmission unit between them. This clamping connection method not only improves the connection strength between the transmission unit and the movable plate but also increases the load-bearing capacity of the movable plate, allowing the driving force of the transmission unit to be more evenly distributed on the movable plate during transmission. As a result, the movable plate experiences more balanced force during reciprocating motion, significantly alleviating local stress concentration and greatly reducing the risk of tearing or deformation of the movable plate during use. This extends the service life of the movable plate and improves the overall reliability and safety of the automatic loading and unloading unit.

[0035] For ease of understanding, please refer to the following: Figures 1 to 4 The present disclosure will be described in detail with reference to an embodiment, including the specific structure and working principle of an automatic loading and unloading unit and an automatic loading and unloading vehicle.

[0036] refer to Figure 1 and Figure 2 This disclosure provides an automatic loading and unloading unit installed inside a vehicle body 1. The unit includes a conveying device and a driving device. The conveying device carries materials, and the driving device drives the conveying device to reciprocate and transport the materials to the outlet of the vehicle body 1. The conveying device includes multiple fixed plates 2 for fixing to the bottom of the vehicle body 1. The multiple fixed plates 2 extend along the length of the vehicle body 1 and are arranged at intervals along the width of the vehicle body 1. The transmission device includes multiple movable plates 3. The movable plates 3 in the conveying device carry the materials to be transported in the vehicle body 1. The multiple movable plates 3 extend along the length of the vehicle body 1, and their two sides in the width direction are respectively configured to guide and cooperate with two adjacent fixed plates 2. At least the movable plates 3 are configured to carry materials.

[0037] Specifically, the automatic loading and unloading unit provided in this disclosure is installed inside the carriage 1 to transport the materials carried in the carriage 1 to the outlet of the carriage 1. The automatic loading and unloading unit consists of two parts, including a conveying device and a driving device. The driving device is used to provide power and drive the conveying device to convey materials. The conveying device includes multiple fixed plates 2 and movable plates 3 extending along the length direction of the carriage 1. The movable plates 3 in the conveying device are used to carry the materials to be transported in the carriage 1. The fixed plates 2 are fixedly connected to the bottom of the carriage 1, and a movable plate 3 is provided between two adjacent fixed plates 2. The two sides of the movable plate 3 in the width direction can respectively guide and cooperate with the adjacent fixed plates 2 and slide relative to the fixed plates 2 in the length direction of the carriage 1 to transport the materials carried on the movable plate 3 to the outlet of the carriage 1.

[0038] The drive unit includes a drive unit 4 and a transmission part 5. The transmission part 5 is configured to extend along the length direction of the movable plate 3. A first connecting plate 6 is provided at the bottom of the movable plate 3, and a second connecting plate 7 is provided at the top of the transmission part 5. The first connecting plate 6, the movable plate 3, the transmission part 5, and the second connecting plate 7 are arranged sequentially in the height direction and are fixedly connected by bolts 8. The transmission part 5 is configured to be controlled by the drive unit 4 to drive the movable plate 3 to reciprocate relative to the fixed plate 2 along the length direction of the carriage 1.

[0039] Specifically, since the vehicle body 1 can transport corrosive materials, including household waste, this disclosure utilizes a sealing structure to create a sealed space at the front of the vehicle body 1 to prevent corrosion of the drive unit. The drive unit is then installed within this sealed space, effectively preventing contact between corrosive materials and the drive unit, thus eliminating the possibility of corrosion. This sealing structure includes a sealing bracket 13 and a sealing plate 14. The sealing bracket 13 is connected to the inner wall of the vehicle body 1 on all four sides. The sealing plate 14 is fixedly installed on the sealing bracket 13 and cooperates with it to form a sealed space at the front of the vehicle body 1. Furthermore, the vehicle body 1 of this disclosure also has a maintenance entrance at the front, allowing maintenance personnel to access the front of the vehicle body 1 for maintenance of the drive unit, reducing the health hazards posed by harmful gases in the materials to maintenance personnel.

[0040] Furthermore, the drive device is equipped with multiple transmission parts 5, all of which are controlled by the drive unit 4 and can start moving under the action of the drive unit 4. Thus, the transmission parts 5 are set above the movable plate 3 as a bridge for transmitting motion. The transmission parts 5 extend along the length direction of the carriage 1 and are shorter than the length of the sealed space in the length direction of the carriage 1. When transporting materials, the multiple transmission parts 5 reciprocate along the length direction of the carriage 1 in the sealed space, and gradually transport the materials carried on the movable plate 3 to the outlet of the carriage 1 through the action of friction.

[0041] For example, suppose the drive unit has 10 transmission units 5, numbered 1, 2...10. When material transport begins, transmission units 1, 3, 5, 7, and 9 move forward a predetermined distance. Due to friction, the material carried on the movable plate 3 moves forward with it. Then, transmission units 2, 4, 6, 8, and 10 also begin to operate. Simultaneously, transmission units 1, 3, 5, 7, and 9 stop and return to their initial positions, preparing for the next cycle. This process is repeated, with each selection of transmission units 5 being pushed while the previously moving units retract. The purpose of this is to create a wave-like effect, allowing the material to move smoothly towards the exit of the carriage 1 during a series of brief pushes.

[0042] To strengthen the connection between the transmission unit 5 and the movable plate 3, this disclosure provides a first connecting plate 6 at the bottom of the movable plate 3 and a second connecting plate 7 at the top of the transmission unit 5. This forms a connection structure in the height direction, with the first connecting plate 6, movable plate 3, transmission unit 5, and second connecting plate 7 arranged sequentially from bottom to top. These components are then connected and fixed using bolts 8. By clamping and fixing the movable plate 3 and transmission unit 5 between the first connecting plate 6 and the second connecting plate 7, the structural strength and stability of the overall connection are effectively enhanced. This clamping connection method allows the driving force of the transmission unit 5 to be more evenly distributed on the movable plate 3 during transmission, resulting in more balanced force distribution during reciprocating motion of the movable plate 3. This prevents localized stress concentration, significantly reducing the risk of tearing or deformation of the movable plate 3 during use, thereby extending its service life and improving the overall reliability and safety of the automatic loading and unloading unit.

[0043] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, the two ends of the transmission part 5 are configured to be fixedly connected to the movable plate 3 by bolts 8, respectively.

[0044] Specifically, to enhance the stability of the connection between the transmission part 5 and the movable plate 3, bolts 8 can be used to connect both ends of the transmission part 5. However, due to the limited thickness of the area where the transmission part 5 connects to the movable plate 3, there are structural problems of insufficient connection strength and limited load-bearing capacity. To improve the connection stability between the transmission part 5 and the movable plate 3 and ensure that power can be effectively transmitted to the movable plate 3, this disclosure provides a first connecting plate 6 at the bottom of the movable plate 3 and a second connecting plate 7 at the top of the transmission part 5. The lengths of the first connecting plate 6 and the second connecting plate 7 are adapted to the length of the transmission part 5, and the first connecting plate 6, the second connecting plate 7, the transmission part 5, and the movable plate 3 are reliably connected by bolts 8. The presence of the first connecting plate 6 and the second connecting plate 7 not only expands the connection area between the transmission part 5 and the movable plate 3, improving the rigidity and stability of the overall structure, but also disperses the stress, avoiding local stress concentration that could lead to damage to the connection structure or tearing of the movable plate 3.

[0045] refer to Figure 2 In one embodiment of this disclosure, a first groove 9 is provided in the middle region of the lower end of the movable plate 3. The first groove 9 is configured to extend through the opposite ends of the movable plate 3 in the length direction. A first connecting plate 6 is configured to be located in the first groove 9 and is configured to fit against the lower end surface of the movable plate 3.

[0046] Specifically, a first groove 9 is provided in the middle area of ​​the lower end of the movable plate 3. The first groove 9 extends from one edge of the movable plate 3 to the other edge, forming an embedded space for accommodating the first connecting plate 6. The first connecting plate 6 is embedded inside the first groove 9 and fits tightly against the bottom surface of the first groove 9. In this way, it can ensure that the force transmission during the transmission process is more uniform and avoid vibration, displacement or stress concentration caused by poor connection. In addition, the first groove 9 and the first connecting plate 6 are connected by bolts 8, which is a detachable structure and facilitates later maintenance and replacement.

[0047] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, the fixed plate 2 is provided with outwardly extending guide rail portions 21 on opposite sides; the movable plate 3 is configured to have downwardly extending extension portions 31 on both sides, and the extension portions 31 are provided with guide grooves 311 that guide and cooperate with the guide rail portions 21; wherein, the extension portions 31 on both sides are configured to form a first groove 9.

[0048] Specifically, guide rails 21 are provided on both sides of the fixed plate 2. These guide rails 21 extend outward from the main body of the fixed plate 2 and upward at a certain angle, forming a guide rail for guiding the movement of the movable plate 3. Extensions 31 are provided at both ends of the movable plate 3. These two extensions 31 extend downward from the sides of the movable plate 3 to form a first groove 9, and a guide groove 311 is provided at the end of each extension 31. This guide groove 311 matches the guide rails 21 on the fixed plate 2 and forms a guiding engagement, allowing the movable plate 3 to slide smoothly with the two adjacent fixed plates 2. The guide rails 21 and the extensions 31 have a certain angle of inclination, which helps reduce frictional resistance during sliding, making it easier for the movable plate 3 to reciprocate under the drive of the transmission unit 5. This ensures the stability of the movable plate 3's movement direction and avoids deviation, jamming, or shaking during movement.

[0049] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, the first connecting plate 6 is provided with a threaded hole, and the bolt 8 passes through the through hole provided on the second connecting plate 7, the transmission part 5, and the movable plate 3 from top to bottom and is then locked with the threaded hole.

[0050] Specifically, to further enhance the stability of the connection structure, this disclosure provides through holes adapted to bolts 8 on the second connecting plate 7, the transmission part 5, and the movable plate 3. These through holes provide a fixing channel for the bolts 8. Since the first connecting plate 6 is located at the bottom of the movable plate 3, at the lowest point of the connection structure, to strengthen the stability of the connection structure, this disclosure provides multiple threaded holes adapted to bolts 8 on the first connecting plate 6. These threaded holes are arranged along the length of the first connecting plate 6 to facilitate fixing the second connecting plate 7, the transmission part 5, the movable plate 3, and the first connecting plate 6 together using bolts 8, and locking them to the first connecting plate 6 through the threaded holes. Compared to fixing methods relying solely on welding, the bolt 8 connection provides higher connection strength and detachability, facilitating later maintenance and replacement.

[0051] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, a second groove 10 is provided in the middle region of the upper end of the movable plate 3, and the transmission part 5 is configured to be disposed in the second groove 10.

[0052] Specifically, the movable plate 3, as the intermediate structure for carrying materials, needs to be connected to the transmission part 5 at its top via a connecting structure. In order to realize the reciprocating motion of the movable plate 3 and drive the materials forward, a second groove 10 for carrying the transmission part 5 needs to be set in the middle area of ​​the upper end of the movable plate 3, thereby optimizing the spatial layout and making the overall structure more compact.

[0053] Furthermore, the middle part of the upper end of the movable plate 3 is the position where the force is most evenly distributed. Installing the transmission part 5 here can make the transmission force more evenly distributed on the entire movable plate 3, reducing the structural deformation or movement direction deviation of the movable plate 3 caused by uneven force distribution.

[0054] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, the transmission part 5 is configured as a tubular structure with a hollow cavity, and the second connecting plate 7 is configured to penetrate into the hollow cavity of the transmission part 5.

[0055] Specifically, the lighter transmission section 5 reduces energy consumption during start-up and shutdown, and improves system response speed. Therefore, this disclosure makes the transmission section 5 a hollow structure, which reduces its weight while ensuring sufficient strength. Furthermore, the second connecting plate 7 passing through the hollow cavity enhances the bending stiffness of the transmission section 5, making it more stable under radial loads.

[0056] refer to Figure 1 and Figure 2 In one embodiment of this disclosure, a notch 11 is provided on the top of the transmission part 5 corresponding to the position of the bolt 8.

[0057] Specifically, in order to facilitate the installation and disassembly of the connection structure between the transmission part 5 and the movable plate 3, this disclosure provides a notch 11 in the area corresponding to the bolt 8 connection position at the top of the hollow cavity of the transmission part 5. The notch 11 provides an operating space for the operator, so that when the operator fixes the second connecting plate 7 to the transmission part 5, it is easier to align the through hole and complete the fastening or disassembly operation.

[0058] refer to Figures 1 to 4 In one embodiment of this disclosure, the bottom of the transmission part 5 is configured to engage with the second groove 10 of the movable plate 3; the drive unit 4 includes a horizontal plate 12 connected to the output end of the drive unit 4, the horizontal plate 12 is configured to connect to the top of the corresponding transmission part 5; the drive unit 4 is configured to drive the corresponding transmission part 5 and the movable plate 3 to move through the horizontal plate 12.

[0059] Specifically, the transmission unit 5 is installed in the second groove 10 on the movable plate 3, so that the transmission unit 5 cooperates with the second groove 10. This allows the transmission force to be distributed more evenly across the entire movable plate 3, reducing structural deformation or deviation in the direction of movement of the movable plate 3 caused by uneven force. The output end of the drive unit 4 is connected to multiple horizontal plates 12. These horizontal plates 12 are arranged along the width direction of the carriage 1 and are all shorter than the width of the carriage 1. That is to say, the horizontal plates 12 do not penetrate the entire transverse space of the carriage 1. Below each horizontal plate 12, several transmission units 5 are connected. These transmission units 5 are responsible for driving the movable plate 3 connected to them to move, thereby using friction to gradually transport the material on the support plate to the outlet of the carriage 1.

[0060] Furthermore, assuming that the drive unit 4 has three horizontal plates 12, denoted as the first horizontal plate, the second horizontal plate, and the third horizontal plate, they are arranged at intervals along the length of the carriage 1 and form a one-to-one connection with the corresponding transmission parts 5. For example, several transmission parts 5 are connected below the first horizontal plate, and these transmission parts 5 are uniformly driven by the first horizontal plate; the second and third horizontal plates drive the transmission parts 5 below them respectively, forming a multi-point drive and zoned control structure. The presence of multiple horizontal plates 12 allows the drive unit 4 to drive different transmission parts 5 in different areas, thereby achieving the drive of the entire movable plate 3. The number and position of the transmission parts 5 driven by each horizontal plate 12 can be flexibly adjusted according to the actual material distribution and the efficiency of friction transmission, thereby improving the uniformity and efficiency of material conveying.

[0061] refer to Figures 1 to 2 This disclosure also discloses an automatic loading and unloading vehicle body 1, including the vehicle body 1 and an automatic loading and unloading unit located inside the vehicle body 1.

[0062] Specifically, this disclosure also discloses, as follows: Figure 1 The automatic loading and unloading vehicle 1 shown has an internal cavity for accommodating materials, and the aforementioned automatic loading and unloading unit is installed in the cavity, including a conveying device and a driving device. The fixed plates 2 in the conveying device are spaced apart along the length of the vehicle 1 at the bottom of the vehicle 1, and the movable plates 3 in the conveying device are guided and engaged with the two adjacent fixed plates 2 to carry materials.

[0063] Furthermore, this disclosure creates a sealed space on the front side of the carriage 1 using a sealing bracket 13, and installs the drive unit within this sealed space, thereby effectively preventing corrosive materials from contacting the drive unit and eliminating the possibility of corrosion of the drive unit by materials. Multiple transmission units 5 in the drive unit are controlled by the drive unit 4. Thus, the transmission units 5, acting as a bridge for transmitting motion, are positioned above the movable plate 3 and fixedly connected to it. Within the sealed space, the multiple transmission units 5 drive the movable plate 3 to reciprocate along the length of the carriage 1, gradually conveying the material carried on the movable plate 3 to the outlet of the carriage 1 through friction.

[0064] The automatic loading and unloading unit and automatic loading and unloading vehicle disclosed herein effectively enhance the structural strength and stability of the overall connection by adding a first connecting plate and a second connecting plate to the drive unit and clamping and fixing the movable plate and the transmission unit between them. This clamping connection method not only improves the load-bearing capacity of the connection point but also distributes the tension applied to the movable plate by the transmission unit during movement more evenly. As a result, the movable plate experiences more balanced force during reciprocating motion, significantly alleviating local stress concentration and greatly reducing the risk of tearing or deformation of the movable plate during use. This extends the service life of the movable plate and improves the overall reliability and safety of the equipment.
