Description

Technical Field

[0001] This utility model relates to an opening mechanism for a transfer box, specifically an opening mechanism for a transfer box, and belongs to the technical field of opening mechanism. Background Technology

[0002] Waste transfer containers are core transfer equipment connecting waste generation sources and final treatment facilities. They are mainly used for centralized collection, temporary storage, and efficient transfer of various types of household waste, kitchen waste, or recyclables, and are widely used in residential areas, commercial areas, industrial parks, and waste transfer stations. Their design typically balances practicality and functionality: in terms of materials, they often use high-strength steel or corrosion-resistant composite materials to resist waste corrosion, external impacts, and the effects of harsh weather, extending their service life; structurally, they are available in sealed and open types (often with lids), and some specialized containers (such as kitchen waste transfer containers) also have leak-proof and odor-proof functions to prevent secondary pollution during transfer; in terms of specifications, they range from small mobile types (suitable for manual or small cleaning vehicles) to large fixed types (connecting to waste compactors and transfer trucks), allowing for flexible matching based on collection volume and transportation vehicles.

[0003] The prior art, patent application number 201420794531.8, entitled "Opening and Closing Device for Transfer Container Door of Vertical Waste Transfer Station," describes a device where a tilting frame is hinged to the upper end of a fixed frame. First drive cylinders on both sides of the fixed frame are hinged to the tilting frame, driving it to rotate around a first pin. A door-hanging beam is fixed between the tilting arms on both sides of the tilting frame. Each end of the beam has a door-hanging sleeve, a first positioning block, and a second positioning block. The door-hanging sleeves are located between the first and second positioning blocks. Door baffles are fixed to both door-hanging sleeves. A connecting extension rod is connected to each door-hanging sleeve on both sides. These two extension rods are connected to a second drive cylinder, which engages and disengages the door-hanging sleeves at both ends from the door mounting brackets. This invention achieves automated opening and closing of the container door, reducing the workload of workers and preventing accidental injuries.

[0004] However, although it does not require operators to connect the container's hydraulic lines to the station's hydraulic system, the door opening mechanism relies on its own independent power or transmission system to open and close the door. If this independent system malfunctions, the door will not be able to open or close properly, and troubleshooting and repair will require a dedicated mechanism, which may increase the difficulty and cost of maintenance. At the same time, if the door opening mechanism is not designed properly, its stability in opening and closing the door may not be as good as that of traditional hydraulic connection methods. When handling heavy waste or in scenarios with extremely high requirements for container sealing, the door may not close tightly, which will affect the transfer efficiency and sealing performance. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a door opening mechanism for a transfer box in order to solve the above-mentioned problems. In this way, the door opening mechanism in the prior art needs to rely on its own independent power or transmission system to open and close the box door. Once the independent system fails (such as mechanical jamming or damage to the power component), the box door will not be able to open or close normally. Furthermore, troubleshooting and repair require a dedicated mechanism, which may increase the difficulty and cost of maintenance.

[0006] This utility model is achieved through the following technical solution: an opening mechanism for a transfer box.

[0007] The enclosure includes a housing with lock holes on both sides and a door on one side. An opening mechanism frame is provided on the outer side of the housing. The lock holes on both sides of the housing can improve locking stability and avoid uneven force on one side. The door provides a channel for the filling material, while the opening mechanism frame provides a stable installation base for each functional component, ensuring the orderly operation of the overall structure.

[0008] Preferably, an opening cylinder is provided on one side of the opening mechanism frame, and a door flipping frame is rotatably connected to one end of the opening cylinder. The opening cylinder provides a stable driving force, and the design of rotatably connecting with the door flipping frame can flexibly drive the door to flip, ensuring that the door can be smoothly opened to a specified angle to meet the filling operation requirements.

[0009] Preferably, a locking cylinder is provided on one side of the door opening mechanism frame, and a locking device fork is provided at one end of the locking cylinder. The locking cylinder provides power for locking and unlocking actions. By driving the locking device fork, power can be accurately transmitted to the subsequent locking components, ensuring that locking and unlocking actions are reliably executed.

[0010] Preferably, a fork slide groove is provided on one side of the door opening mechanism frame, and one side of the locking device fork is slidably connected to the fork slide groove. The fork slide groove provides motion guidance for the locking device fork, restricts the movement trajectory of the fork, avoids fork deviation leading to action failure, and ensures that the fork can accurately cooperate with other components.

[0011] Preferably, the door opening mechanism frame, the box door flipping frame, and the fork slide are all equipped with sensors. The multiple sensors can comprehensively sense the position status of each component and provide real-time feedback of electrical signals, which facilitates accurate judgment of the working status of the mechanism and improves operational safety and work accuracy.

[0012] Preferably, a three-point locking device is provided on one side of the door opening mechanism frame, and a three-point locking device lever is provided on one side of the three-point locking device. The three-point locking device can enhance the connection stability between the box and the door opening mechanism. As a force transmission component, the lever can effectively bear the driving force of the locking device lever fork, laying the foundation for subsequent linkage actions.

[0013] Preferably, one side of the three-point locking device lever of the housing contacts the locking device fork, and both sides of the three-point locking device lever of the housing are provided with a three-point locking device connecting rod. The lever and the locking device fork are in direct contact to ensure efficient power transmission. The connecting rods on both sides can be driven synchronously, making the locking and unlocking actions more balanced and avoiding damage to components caused by force on one side.

[0014] Preferably, one end of the connecting rod of the three-point locking device for the box is connected to the lever of the three-point locking device for the box, and the other end of the connecting rod extends to the inside of the lock hole of the box. The connecting rod is connected to the lever and extends to the lock hole. The lever can drive the connecting rod to be inserted and pulled out of the lock hole, accurately completing the locking and unlocking, and ensuring the reliable connection and separation of the box and the door opening mechanism.

[0015] This utility model provides an opening mechanism for a transfer box, which has the following beneficial effects:

[0016] 1. This door opening mechanism for transport containers, through an automatic door control and load reduction mechanism, can replace traditional manual operation, significantly reducing the physical exertion of workers pushing and pulling heavy container doors, reducing reliance on dedicated door operators and thus lowering labor costs. Simultaneously, relying on a preset program, it precisely controls the door opening angle, speed, and start / stop timing, avoiding the risk of work-related injuries such as hand squeezing and back sprains caused by door inertia and seal jamming, ensuring personnel safety. Furthermore, through the collaboration of hydraulic cylinders and sensors, it achieves automated and standardized execution of door control actions, ensuring precise door positioning, reducing problems such as packing leakage and insufficient compression caused by door control deviations, and improving operational efficiency. Moreover, the stable output of the mechanical drive can adapt to high-frequency continuous transport operations, avoiding additional wear on components caused by uneven manual operation force, and extending the service life of the door opening mechanism and the container door.

[0017] 2. The door opening mechanism for the transfer box utilizes a wide-fork adaptation and compatibility mechanism (the core of which is a wide-width locking device fork and a matching guide structure). This mechanism expands the contact adaptation range with the three-point locking device blocks of transfer boxes of different sizes and models. It is compatible with small standard boxes and non-standard boxes without the need to replace the fork separately, improving the versatility of the mechanism and reducing equipment replacement costs. Its wider fork contact area allows for a certain positional deviation when the boxes are docked, eliminating the need for repeated high-precision calibration, shortening docking time and improving work efficiency. At the same time, the larger contact area can stably wrap or fit the block, preventing the fork from separating from the block due to transport bumps. This ensures that the connecting rod accurately inserts into the lock hole when locking and smoothly pulls out when unlocking, preventing the box from falling off and material leakage. It also distributes the force to a wider contact surface, reducing the force intensity per unit area, reducing the wear rate of the fork and block, extending the component replacement cycle, and reducing maintenance costs and downtime for repairs.

[0029] This utility model embodiment provides a door opening mechanism for a transfer box.

[0030] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a box body 1, with lock holes 101 on both sides of the box body 1, a door 102 on one side of the box body 1, and a door opening mechanism frame 2 on the outside of the box body 1.

[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A door opening mechanism frame 2 is provided with a door opening cylinder 201 on one side. One end of the door opening cylinder 201 is rotatably connected to a door flipping frame 3. A locking cylinder 4 is provided with a locking device fork 401 on one end of the locking cylinder 4. A fork slide groove 402 is provided with a side of the door opening mechanism frame 2. One side of the locking device fork 401 is slidably connected to the fork slide groove 402. Sensors are provided in the door opening mechanism frame 2, the door flipping frame 3 and the fork slide groove 402.

[0032] The automatic door control load reduction mechanism is based on the door opening mechanism frame 2. Its core consists of a door opening cylinder 201, a door flipping frame 3, and a sensor 5. The aim is to replace manual operation with automated drive, achieving labor-saving and precise control of the opening and closing of the door 102. When the door 102 needs to be opened, the system first confirms via the sensor 5 at the fork slide groove 402 that the locking device fork 401 has unlocked the three-point locking device of the box body (connecting rod 602 is pulled out of the box body lock hole 101). Then, it sends a telescopic command to the door opening cylinder 201, causing the piston rod of the cylinder to extend. Because one end of the piston rod is rotatably connected to the door flipping frame 3, the driving force is transmitted to the door flipping frame 3, causing it to rotate around the connection point. Simultaneously, the door flipping frame 3 and the door 102 of the box body 1... The system drives the door 102 to rotate synchronously until the sensor 5 (installed on the door flipping frame 3 or the door opening mechanism frame 2) detects that the door 102 has opened to the preset 135° position. At this point, the door opening cylinder 201 stops operating, completing the door opening. When the door 102 needs to be closed, the system receives a closing signal and controls the piston rod of the door opening cylinder 201 to retract. This retracts the piston rod, which in turn drives the door 102 to rotate in the opposite direction through the door flipping frame 3 until the door 102 is sealed and fitted with the box body 1. At this point, the sensor 5 at the door flipping frame 3 sends a signal indicating that the door is in position, and the door opening cylinder 201 stops retracting, completing the door closing. The entire process does not require manual pushing or pulling of the door. Through the hydraulic cylinder drive and precise monitoring by the sensor, the system reduces the intensity of manual labor and avoids positional deviations caused by manual operation, ensuring stable and reliable door control.

[0033] Example 2, please refer to again. Figure 1 , Figure 2 , Figure 3 and Figure 4A three-point locking device 6 is provided on one side of the door opening mechanism frame 2. A three-point locking device lever 601 is provided on one side of the three-point locking device 6. One side of the three-point locking device lever 601 is in contact with the locking device lever fork 401. A three-point locking device connecting rod 602 is provided on both sides of the three-point locking device lever 601. One end of the three-point locking device connecting rod 602 is connected to the three-point locking device lever 601, and the other end of the three-point locking device connecting rod 602 extends to the inside of the lock hole 101.

[0034] The wide-fork compatible mechanism is centered on the locking device fork 401 (wide design), in conjunction with the fork slide 402, locking cylinder 4, and three-point locking device 6. By expanding the contact adaptation range between the fork and the block, it achieves compatible locking and unlocking for different sizes of cabinets 1. When the cabinet 1 is connected to the opening mechanism, even if there are slight differences in the position of the three-point locking device block 601 of different cabinets 1 (such as left-right offset or height deviation), the wide-designed locking device fork 401 can still cover the block 601 with a larger contact area. When unlocking is required, the piston rod of the locking cylinder 4 retracts after receiving the command, driving the locking device fork 401 to slide along the fork slide 402 towards the locking cylinder 4. After the fork of the wide-width fork contacts the three-point locking device block 601 of the cabinet, it can stably hook the block 601 and lift it to the upper limit position. By pulling the lever 601, the connecting rods 602 on both sides retract synchronously, causing the connecting rods 602 to be pulled out of the lock hole 101 of the housing, thus completing the unlocking. Because the width of the lever fork is sufficient, even if the position of the lever 601 is deviated, it can prevent the lever fork from disengaging from the lever block, ensuring a smooth unlocking action. When locking is required, the piston rod of the locking cylinder 4 extends, pushing the locking device lever fork 401 to slide along the lever fork slide groove 402 away from the locking cylinder 4. The fork of the wide lever fork presses the three-point locking device lever 601 of the housing, causing the lever 601 to descend to the lower limit position, thereby pushing the connecting rods 602 on both sides to extend and accurately insert into the lock holes 101 of the housing 1 on both sides. The wide lever fork can ensure that the pressing force is evenly applied to the lever 601, avoiding the problem of one-sided connecting rod not being inserted due to the position deviation of the lever, realizing stable locking of housings of different specifications and improving the adaptability of the mechanism.

[0035] Working Principle: The automatic door control load reduction mechanism is based on the door opening mechanism frame 2. Its core consists of the door opening cylinder 201, the door flipping frame 3, and the sensor 5. The aim is to replace manual operation with automated drive, achieving labor-saving and precise control of the opening and closing of the door 102. When the door 102 needs to be opened, the system first confirms through the sensor 5 at the fork slide groove 402 that the locking device fork 401 has unlocked the three-point locking device of the box body (connecting rod 602 is pulled out of the lock hole 101). Then, it sends a telescopic command to the door opening cylinder 201, causing the piston rod of the cylinder to extend. One end of the piston rod rotates with the door flipping frame 3. Upon connection, the driving force is transmitted to the door flipping frame 3, causing it to rotate around the connection point. Simultaneously, the door flipping frame 3 connects to the door 102 of the container 1, causing the door 102 to rotate synchronously until the sensor 5 (installed on the door flipping frame 3 or the door opening mechanism frame 2) detects that the door 102 has opened to a preset 135° position. At this point, the door opening cylinder 201 stops operating, completing the door opening. When it is necessary to close the door 102, the system receives a closing signal and controls the piston rod of the door opening cylinder 201 to retract, causing the door flipping frame 3 to rotate in the opposite direction until the door 102 is sealed tightly against the container 1. Sensor 5 at door tilting frame 3 provides a positioning signal, causing door opening cylinder 201 to stop retracting and close the door. The entire process requires no manual pushing or pulling of the door. Through cylinder drive and precise sensor monitoring, it reduces manual labor intensity and avoids positional deviations during manual operation, ensuring stable and reliable door control. The wide-fork compatible mechanism, with locking device fork 401 (wide design) as its core, works in conjunction with fork slide 402, locking cylinder 4, and three-point locking device 6. By expanding the contact range between the fork and the block, it achieves compatible locking and unlocking for different sizes of cabinets 1. When cabinet 1 is connected to the door opening mechanism, even if different cabinets 1 have different three-point locking mechanisms... Even with slight differences in the position of the locking device lever 601 (such as left-right offset or height deviation), the wide-width locking device lever fork 401 can still cover the lever 601 with a larger contact area. When unlocking is required, the piston rod of the locking cylinder 4 retracts after receiving the command, causing the locking device lever fork 401 to slide along the lever fork slide groove 402 towards the direction closer to the locking cylinder 4. After the fork of the wide lever fork contacts the three-point locking device lever 601 of the housing, it can stably hook the lever 601 and drive it to rise to the upper limit position. Then, the lever 601 pulls the connecting rods 602 on both sides to retract synchronously, causing the connecting rods 602 to be pulled out of the housing lock hole 101, thus completing the unlocking.Furthermore, due to the sufficient width of the shift fork, even if the position of the shift block 601 is off, it can prevent the shift fork from disengaging from the shift block, ensuring a smooth unlocking action. When locking is required, the piston rod of the locking cylinder 4 extends, pushing the locking device shift fork 401 to slide along the shift fork slide groove 402 away from the locking cylinder 4. The wide shift fork presses against the shift block 601 of the three-point locking device of the housing, causing the shift block 601 to descend to the lower limit position, thereby pushing the connecting rods 602 on both sides to extend and accurately insert into the housing lock holes 101 on both sides of the housing 1. The wide shift fork ensures that the pressing force is evenly applied to the shift block 601, avoiding the problem of one-sided connecting rods not being inserted properly due to the positional deviation of the shift block, achieving stable locking of housings of different specifications and improving the adaptability of the mechanism.
