Abstract
Description
An automatic container door opening device and a waste transfer station Technical Field
[0001] This application relates to the technical field of waste transfer stations, and in particular to an automatic container door opening device and a waste transfer station. Background Technology
[0002] Waste transfer stations are used to collect and transfer waste delivered by containers. The external dimensions and structure of existing internationally accepted standard containers are subject to strict standard specifications. The tail door structure of containers of different sizes is basically the same, consisting of two door leaves on the left and right. Each door leaf has a locking mechanism with pin holes, and the tail door can rotate approximately 270°.
[0003] In existing technologies, the rear doors of containers in waste transfer stations can only be opened manually. This is because the unique structural standards of containers limit the addition of any other automated equipment to achieve automatic opening. However, with the widespread use of containers and their increasingly diverse applications, manually opening the rear doors presents a series of problems. When the composition of household waste is relatively complex and the container is full, the moment the rear door opens, household waste and sewage will fall and overflow. At this time, the staff opening the door risk tripping over the rear door, being injured by falling objects, or being splashed with sewage. Therefore, there is a need for automated opening of the container rear doors.
[0004] The current common practice is to modify the rear door of the container by adding a device to the outside of the container and changing the opening method of the rear door to achieve automatic opening. However, such modifications turn a standard container into a non-standard container, which cannot be adapted to standard containers. Even if ordinary rigid mechanical equipment such as robotic arms or other similar movable mechanical mechanisms can achieve automatic opening of the container, these solutions are very complex and costly. At the same time, they all have a very serious safety problem: once the locking mechanism of the container rear door is released, the domestic waste and sewage loaded in the container may suddenly slip out, causing the container rear door to open suddenly. If the robotic arm or other mechanical structure cannot avoid it in time, the equipment may be damaged. Summary of the Invention

[0032] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] In some embodiments, as shown in Figures 1 and 2, this application provides a waste transfer station, including a site 1, an unloading pit 2, and an automatic container door opening device. The waste transfer station collects and transfers waste delivered by containers 3. Figures 1 and 2 correspond to the specific structures of two different automatic container door opening devices, respectively.
[0034] Specifically, as a preferred embodiment, as shown in Figures 1 and 2, the number of automatic container door opening devices can be two, with the two automatic container door opening devices respectively located on both sides of the unloading pit.
[0035] In some embodiments, the automatic container door opening device is used to automatically open the rear door of the container, and the rear door is provided with a first locking mechanism and a second locking mechanism.
[0036] Specifically, the standard container's rear door has four locking lever devices, with two locking lever devices on each door. The two locking lever devices on the left door constitute the first locking lever mechanism, and the two locking lever devices 24 and 25 on the right door constitute the second locking lever mechanism. The container doors are opened by first opening the right door and then the left door. Since there are many types of containers, but the locking lever mechanisms are basically the same—all being rotary unlocking structures—the automatic container door opening device of this application can drive the first locking lever mechanism and / or the second locking lever structure to rotate.
[0037] In some embodiments, the automatic container door opening device includes a rotary drive assembly, a pulley block, a traction assembly, and a mounting bracket assembly; the traction assembly is connected to the mounting bracket, and the traction assembly is connected to the rotary drive assembly via the pulley block; the mounting bracket assembly is used to connect the first locking rod mechanism and / or the second locking rod mechanism; the rotary drive assembly drives the first locking rod mechanism and / or the second locking rod mechanism to rotate via the traction assembly, the pulley block, and the mounting bracket.
[0038] Specifically, as a preferred embodiment, as shown in Figure 1, the second locking rod mechanism includes a first locking rod device 24; the rotary drive assembly includes a first rotary driver 4; the pulley group includes a first fixed pulley 8, a first support mechanism, a second fixed pulley 12, and a second support mechanism; the traction assembly includes a first wire rope 17; and the hanging device includes a first hook 20; the first hook 20 is used to hook the first locking rod device 24.
[0039] The first fixed pulley 8 is vertically mounted on the first support mechanism, the second fixed pulley 12 is horizontally mounted on the second support mechanism, and the first wire rope 17 is sequentially connected to the first rotary driver 4, the first fixed pulley 8, the second fixed pulley 12, and the first hook 20.
[0040] As a preferred embodiment, as shown in Figure 1, the second locking rod mechanism further includes a second locking rod device 25, and the opening rotation directions of the first locking rod device 24 and the second locking rod device 25 are the same; the hanger further includes a second hook 201; the tail end of the first wire rope 17 includes a first hanging rope 171 and a second hanging rope 172; the first hanging rope 171 is used to connect the first hook 20, and the second hanging rope 172 is used to connect the second hook 201; the second hook 201 is used to hook the second locking rod device 25.
[0041] Specifically, in some embodiments, as shown in Figure 1, the locking lever mechanisms on both sides of the container open and rotate in the same direction. For example, the locking lever mechanisms on the right side of the container can all rotate counter-clockwise, and the locking lever mechanisms on the left side can all rotate clockwise. To address this, the tailgate is opened by simultaneously rotating the first hook 20 and the second hook 201 using the first rotary actuator 4. The specific implementation steps are as follows: First, the transport vehicle carrying the container 3 enters the unloading area 1 and parks the container 3 near the unloading pit 2. Then, the operator releases the first locking lever device 24 and the second locking lever device 25 from the container 3 (the container's locking lever mechanism may be fitted with a lead seal or other safety device, which the operator needs to remove during this process). After releasing the first locking lever device 24 and the second locking lever device 25, the first hook 20 and the second hook 201 are connected to the pin holes of the first locking lever device 24 and the second locking lever device 25. At this time, the first hook 20 and the second hook 201 are connected by the first hanging rope 171 and the second hanging rope 172 at the tail end of the first wire rope 17. The other two locking devices are connected to the hooks using the same method. After hooking, the transport vehicle can park container 3 at the unloading position according to site requirements. At this time, the operator operates the remote control of the door opening mechanism to control the first rotary drive 4. Under the action of the first rotary drive 4, the first hook 20 and the second hook 201 drive the first locking device 24 and the second locking device 25 of the right tail door of container 3 to rotate. When the first locking device 24 and the second locking device 25 of container 3 rotate more than 90°, the right tail door is unlocked. Then, the operator uses the remote control to operate the third rotary drive 6 to open the two locking devices of the left tail door of the container, thus completing the opening of the container tail door. Finally, the operator releases the action of the first rotary drive 4 and the third rotary drive 6, allowing them to move freely, and the container can begin unloading. Before the transport vehicle leaves site 1 after unloading, the operator removes all four hooks. The operation is complete.
[0042] In some embodiments, as a preferred solution, as shown in FIG2, the second locking mechanism includes a first locking device 24 and a second locking device 25, and the opening rotation directions of the first locking device 24 and the second locking device 25 are opposite. Similarly, the opening rotation directions of the two locking devices of the first locking mechanism are also opposite.
[0043] The rotary drive assembly further includes a second rotary driver 5; the pulley block further includes a third fixed pulley 9, a third support mechanism, a fourth fixed pulley 13, and a fourth support mechanism; the traction assembly further includes a second wire rope 16; the hanging device further includes a third hook 23;
[0044] The third fixed pulley 9 is vertically mounted on the third support mechanism, the fourth fixed pulley 13 is horizontally mounted on the fourth support mechanism, and the second wire rope 16 is sequentially connected to the second rotary driver 5, the third fixed pulley 9, the fourth fixed pulley 13, and the third hook 23.
[0045] The first hook 20 is used to connect to the first locking lever mechanism, and the third hook 23 is used to connect to the second locking lever mechanism; alternatively, the first hook 20 is used to connect to the second locking lever mechanism, and the third hook 23 is used to connect to the first locking lever mechanism; or the first hook 20 and the third hook 23 are used to connect to the first locking lever mechanism; or the first hook 20 and the third hook 23 are used to connect to the second locking lever mechanism. The specific connection method between the hook and the tailgate locking lever mechanism can be adjusted according to the opening rotation direction of the container tailgate locking lever device. Different opening directions can be achieved through different combinations of the hook and the locking lever device.
[0046] As a preferred embodiment, the first rotary drive includes a motor and a turntable, with the head end of the first wire rope 17 wound around the turntable.
[0047] In some embodiments, as a preferred solution, as shown in Figures 1-3, the first fixed pulley 8 is vertically disposed on the first support mechanism; the first support mechanism includes an inner column 801, an outer column 802, and a positioning mechanism; the first fixed pulley is disposed on the inner column 801, the inner column 801 is sleeved inside the outer column 802, and the inner column 801 can move up and down within the outer column 802 and is positioned by the positioning mechanism to adjust the height of the first fixed pulley 8.
[0048] As a preferred embodiment, the positioning mechanism includes a cotter pin 804 and a pin 803; the outer column 802 is provided with a plurality of first positioning holes 805 / 806 / 807 / 808, and the inner column 801 is provided with a second positioning hole; the inner column 801 moves up and down within the outer column 802, and when the second positioning hole and the first positioning hole are aligned, the cotter pin 804 and the pin 803 are inserted into the second positioning hole and the first positioning hole for positioning.
[0049] As shown in Figure 3, when height adjustment is needed, first remove the cotter pin 804, then pull out the pin 803, raise the inner column 801 to hole position 806, and then reinstall the pin 803 and cotter pin 804. This completes the height adjustment. The same method can be used to adjust the height of the inner column 801 to holes 807 and 808.
[0050] In some embodiments, as a preferred option, a controller is further included, coupled to the rotary drive assembly; the controller is used to control the rotary drive assembly to drive the first locking rod mechanism and / or the second locking rod mechanism to rotate 90° via the traction assembly, the pulley block and the hanger.
[0051] In some embodiments, specifically as shown in Figures 2 and 3, the opening and rotation directions of the two locking devices of the first and second locking mechanisms of the tailgate of container 3 are opposite. First, the transport vehicle carrying container 3 enters the unloading area 1 and parks container 3 near the unloading pit 2. Then, the operator releases the first locking device 24 and the second locking device 25 from the container (the container's locking mechanism is fitted with a lead seal or other safety device, which the operator must remove during this process). After releasing the first locking device 24 and the second locking device 25, the first hook 20 is simultaneously connected to the first locking device 24, and the fourth hook 21 is connected to the pin hole of the second locking device 25. The other two locking devices are connected to the fifth hook 22 and the third hook 23 respectively using the same method. After the container is properly attached, the transport vehicle can park container 3 at the unloading position according to site requirements. At this point, the operator uses the remote control of the door opening mechanism to control the first rotary actuator 4 and the third rotary actuator 6. Under the action of the first rotary actuator 4 and the third rotary actuator 6, the first hook 20 and the fourth hook 21 drive the first locking lever device 24 and the second locking lever device 25 of the right rear door of the container to rotate. When the first locking lever device 24 and the second locking lever device 25 of container 3 rotate more than 90°, the right rear door is unlocked. Then, the operator uses the remote control to operate the second rotary actuator 5 and the fourth rotary actuator 7 to open the two locking lever devices of the left rear door of the container, thus unlocking the container rear door. Finally, the operator releases the action of the first, second, third, and fourth rotary actuators 4, 5, 6, and 7, allowing them to move freely. Container 3 can then begin unloading. Before the transport vehicle leaves site 1 after unloading, the operator removes the first, fourth, fifth, and third hooks 20, 21, 22, and 23. The operation is complete.
[0052] Different types of container tailgate locking levers rotate in different directions, either left-hand or right-hand. The handle heights also vary; not all four lever handles are on the same horizontal plane. This application addresses these variations by requiring the operator to pay attention to the rotation direction of the locking lever when connecting the hooks. For example, to rotate right, use the right-hand hooks (e.g., fourth hook 21 and fifth hook 22); to rotate left, use the left-hand hooks (e.g., first hook 20 and third hook 23). Regarding the handle height, this application uses a wire rope drive, which allows for some inherent error. Furthermore, the fixed pulleys 8, 9, 10, 11, 12, 13, 14, and 15 are designed to be height-adjustable, allowing for adjustments as needed.
[0053] This application discloses an automatic rear door opening device for standard containers and a waste transfer station. The device comprises a rotary drive, fixed pulleys, a wire rope, a hook, and a control system. The rotary drive consists of a motor and a turntable connected to the wire rope, enabling the rope to extend and retract. Two sets of fixed pulleys are installed on the front of the rotary drive; one set is vertically installed, and the other is horizontally installed. The vertically installed pulley adjusts the height of the wire rope, while the horizontally installed pulley adjusts the angle at which the wire rope connects to the container door locking mechanism. A hook is installed at the other end of the wire rope, the size of which matches the handle bolt hole on the locking mechanism of the container door opening structure. The rotary drive is controlled by a control system equipped with a remote control, which allows control of the rotary drive's operation, thus extending and retracting the wire rope.
[0054] Since there are many types of containers, but the locking mechanism of different containers is basically the same, all of which are rotary unlocking structures, this application is fully compatible with different types of containers and can realize automatic opening of containers.
[0055] The rotary actuator of this application has a motor and a turntable installed inside. The turntable is connected to a wire rope. The motor drives the turntable to rotate, causing the wire rope to wind around the turntable, thereby realizing the elongation and shortening of the wire rope.
[0056] The fixed pulleys of this application can be set into two or more sets according to the on-site working conditions. The first set of fixed pulleys makes the wire rope flush with the locking bar device of the container that needs to be opened after passing over the fixed pulley. When the wire rope passes over the fixed pulley and connects with the container locking bar mechanism, the angle of the second set of fixed pulleys can be automatically adjusted so that there is no need to worry about the wire rope derailing or other problems.
[0057] Furthermore, the height of the fixed pulley is designed to be adjustable, allowing for adjustments as needed. The hook in this application is shaped like a lifting hook, designed to connect to the container locking mechanism. One end of the hook is connected to a wire rope, allowing the locking mechanism to rotate during the pulling of the wire rope, thus enabling the door to open.
[0058] The positions of the rotary drive device and the fixed pulley, as well as the length of the wire rope in the device of this application, need to be reasonably arranged and installed according to the conditions of the container unloading site. The rotary drive device is preferably installed on both sides of the unloading pit as far away from the unloading side as possible, so as to avoid being damaged by other debris.
[0059] This application allows for the installation of vertical and horizontal fixed pulleys, ensuring that the angle between the wire rope and the locking mechanism is less than 90° and greater than 0° when the wire rope pulls the container locking mechanism. This automatic adjustment eliminates concerns about the wire rope derailing from the pulleys. Furthermore, the installation height of the fixed pulleys is designed to be freely adjustable, ensuring that the height of the wire rope is essentially flush with the height of the container locking device, thus increasing the stability of the device. The length of the wire rope can be configured according to site requirements, with a basic length being the distance from the installation position of the rotary drive to the position where the container is prepared for reversing into place before unloading.
[0060] Furthermore, the fixed pulley system of this application is designed for height adjustment. The pulley system's uprights consist of inner and outer layers. The inner upright can slide up and down along the outer upright. Both the inner and outer uprights are designed with positioning holes. A pin passes through the positioning holes and is fixed with a cotter pin. When height adjustment is required, simply move the inner upright up and down until the inner and outer positioning holes on the upright are aligned, and then re-fix it with the pin to complete the height adjustment.
[0061] This application addresses the problems associated with using existing rigid mechanical devices such as robotic arms or other similar movable mechanical mechanisms to automatically open container doors. These solutions are complex and costly, and also present a serious safety issue: if the locking mechanism of the container tail door is disengaged, the cargo loaded in the container may suddenly slip, causing the tail door to open abruptly. If the robotic arm or other mechanical structure cannot avoid this sudden movement, damage may occur. This application utilizes a steel wire rope to pull the container's locking mechanism to open the door. The flexibility of the steel wire rope easily eliminates and offsets the effects of sudden load changes without damaging the rope. The ingenious and refined design of this application achieves efficient, stable, and reliable automatic opening of standard container tail doors. It offers advantages such as low cost, convenient installation and maintenance, and overcomes the long-standing limitation that standard container tail doors can only be opened manually, allowing for widespread application.
[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The above-described embodiments are merely illustrative of several implementation methods of this application and are only used to illustrate the technical solutions of this application, not to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application. For those skilled in the art, several variations and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application.
