Description

Technical Field

[0001] This utility model relates to the technical field of waste transfer, and in particular to an automatic locking mechanism for waste containers. Background Technology

[0002] With the rapid advancement of urbanization, the resident population of large and medium-sized cities has surged dramatically, leading to a significant increase in the amount of urban household waste generated. This change places more stringent demands on the processing capacity of waste transfer stations. Simultaneously, the continuous improvement of people's living standards has prompted a growing societal focus on safety, particularly in the household waste transfer process, where safety requirements have reached unprecedented levels.

[0003] In the current waste transfer process, detachable garbage trucks are mainly used. Although these garbage trucks have the advantage of being able to accommodate multiple containers, in actual transfer, especially when passing through bumpy sections or making sharp turns, garbage containers often detach from the superstructure. This not only seriously affects the normal operation of waste transfer work, but also poses a potential threat to the surrounding environment and personnel safety. Utility Model Content

[0004] In view of the aforementioned problems in existing waste transfer systems, this paper aims to provide an automatic container locking mechanism.

[0005] The specific technical solution is as follows:

[0006] An automatic container locking mechanism includes: a support beam for supporting a container, the support beam having at least one locking assembly for longitudinally limiting and locking the container, the locking assembly comprising:

[0007] Two locking blocks are arranged opposite each other and can be slidably mounted on the support beam, moving away from or close to each other. The opposite end faces of the two locking blocks each have a locking part.

[0008] Two limiting plates are provided on the support beam and located between the two locking blocks, and the two limiting plates and the two locking blocks respectively form two locking areas;

[0009] Two bottom beams are provided on the container and supported on the support beam. They are located between the two locking areas respectively. Limiting steps are provided on the side of the two bottom beams that are far apart from each other.

[0010] A driving component is connected to the two locking blocks in a transmission manner, and is used to drive the two locking blocks to move closer to each other, so that the two locking parts move to the top of the two limiting steps respectively, thereby locking and limiting the two limiting steps longitudinally.

[0011] As a further improvement and optimization of this solution, the tops of both limiting plates are inclined toward the side that is close to each other.

[0012] As a further improvement and optimization of this solution, the support beam has multiple support components, which are arranged along the length of the bottom beam. Each support component includes two guide rollers, which are rotatably mounted on the support beam and support the bottom of the two bottom beams respectively.

[0013] As a further improvement and optimization of this solution, the driving component is a double-rod hydraulic cylinder, and the two piston rods of the double-rod hydraulic cylinder are respectively connected to the two locking blocks.

[0014] As a further improvement and optimization of this solution, the piston rod and the locking block are connected by a pull rod. The pull rod can be slidably mounted on the support beam along its own axis, and the axis of the pull rod is set along the sliding direction of the locking block.

[0015] As a further improvement and optimization of this solution, the pull rod is hinged to the piston rod.

[0016] As a further improvement and optimization of this solution, a support plate mounted on the support beam is provided between each of the limiting plates and the double-rod hydraulic cylinder, and a guide sleeve is provided between the support plate and the limiting plate, and the pull rod is slidably disposed coaxially within the guide sleeve.

[0017] As a further improvement and optimization of this solution, the locking assembly also includes two first limiting blocks installed on the support beam. The two first limiting blocks are respectively located on the side where the two locking blocks are close to each other. When the two locking blocks are respectively in limiting contact with the two first limiting blocks, the two locking parts are respectively longitudinally locked and limited by the two limiting steps.

[0018] As a further improvement and optimization of this solution, it also includes two second limiting blocks installed on the support beam. The two second limiting blocks are respectively located on the side away from each other of the two locking blocks. When the two locking blocks respectively make limiting contact with the two second limiting blocks, the two locking parts disengage from the two limiting steps respectively.

[0019] As a further improvement and optimization of this solution, the locking part is a rolling bearing.

[0020] The positive effects of the above technical solution compared with the existing technology are:

[0021] (1) By setting a locking component, the present invention uses a driving component to drive two locking blocks to approach each other, so that the locking part moves to the top of the limiting step to achieve longitudinal locking and limiting, effectively preventing the garbage container from moving up and down during the transfer process, and greatly improving the safety of the garbage transfer process.

[0022] (2) The top of the limiting plate of this utility model is inclined, which can better guide the bottom beam of the container into the locking area.

[0023] (3) The multiple support components and guide rollers of this utility model provide stable and uniform support for the bottom beam of the container. At the same time, the guide rollers can reduce the friction between the bottom beam and the support beam, making the container more stable and smooth during placement and movement, reducing wear and extending the service life of the equipment.

[0024] (4) The pull rod and piston rod of this utility model are hinged, so that there is a certain degree of rotational freedom between them, which can adapt to the force transmission at different angles, reduce stress concentration caused by installation errors or angle changes during movement, reduce the risk of component damage, and improve the durability of the mechanism.

[0025] (5) The limiting part of this utility model is designed as a rolling bearing, which can greatly reduce the friction between the locking part and the limiting step, reduce component wear, and extend the service life of the equipment. Attached Figure Description

Figure 1-3 The diagram illustrates an automatic container locking mechanism according to a preferred embodiment, comprising: a support beam 1 for supporting a container; the support beam 1 having at least one locking assembly 3 for longitudinally limiting and locking the container; the locking assembly 3 including two locking blocks 32, two limiting plates 33, two bottom beams 39, and a driving member 31; the two locking blocks 32 being disposed opposite to each other and slidably mounted on the support beam 1, capable of moving away from or close to each other; each locking block 32 having a locking portion 321 on its opposite end face; and the two limiting plates 33 being disposed on the support beam 1 and located at the two locking blocks 39. Between the blocks 32, and between the two limiting plates 33 and the two locking blocks 32 respectively, two locking areas are formed. The two bottom beams 39 are both provided on the container and supported on the support beam 1, and are located between the two locking areas respectively. The two bottom beams 39 are provided with limiting steps 391 on the side away from each other. The driving member 31 is connected to the two locking blocks 32 for driving the two locking blocks 32 to move closer to each other, so that the two locking parts 321 move to the top of the two limiting steps 391 respectively, thereby locking and limiting the two limiting steps 391 longitudinally.

[0034] In this application, by setting a locking component 3, the driving component 31 drives the two locking blocks 32 to move closer to each other, so that the locking part 321 moves to the top of the limiting step 391 to achieve longitudinal locking and limiting, effectively preventing the garbage container from moving up and down during the transfer process, and greatly improving the safety of the garbage transfer process.

[0035] Furthermore, as a preferred embodiment, the tops of both limiting plates 33 are inclined toward each other. Specifically, the inclined tops of the limiting plates 33 can better guide the bottom beam 39 of the container into the locking area.

[0036] Furthermore, in a preferred embodiment, the support beam 1 has multiple support components 2, which are arranged along the length of the bottom beam 39. Each support component 2 includes two guide rollers 21, which are rotatably mounted on the support beam 1 and respectively support the bottom of the two bottom beams 39. Specifically, the arrangement of multiple support components 2 and guide rollers 21 provides stable and uniform support for the container bottom beam 39. At the same time, the guide rollers 21 can reduce the friction between the bottom beam 39 and the support beam 1, making the container more stable and smooth during placement and movement, reducing wear, and extending the service life of the equipment.

[0037] Furthermore, as a preferred embodiment, the driving component 31 is a double-rod hydraulic cylinder, with its two piston rods connected to the two locking blocks 32 respectively. Specifically, using a double-rod hydraulic cylinder as the driving component 31 provides a stable and powerful driving force, ensuring that the two locking blocks 32 can accurately and reliably move closer or further apart, thereby guaranteeing the stability of the locking and unlocking actions and improving the reliability of the entire automatic locking mechanism.

[0038] Furthermore, as a preferred embodiment, the piston rod and the locking block 32 are connected by a pull rod 34, which is slidably mounted on the support beam 1 along its own axial direction, and the axial direction of the pull rod 34 is set along the sliding direction of the locking block 32.

[0039] Furthermore, as a preferred embodiment, the pull rod 34 is hinged to the piston rod. Specifically, the hinged connection between the pull rod 34 and the piston rod provides a certain degree of rotational freedom, enabling it to adapt to force transmission at different angles, reducing stress concentration caused by installation errors or angle changes during movement, lowering the risk of component damage, and improving the durability of the mechanism.

[0040] Furthermore, in a preferred embodiment, a support plate 35 mounted on the support beam 1 is provided between each limiting plate 33 and the double-rod hydraulic cylinder. A guide sleeve 36 is provided between the support plate 35 and the limiting plate 33, and the pull rod 34 is coaxially slidably disposed within the guide sleeve 36. Specifically, the support plate 35 and the guide sleeve 36 provide precise guidance and stable support for the pull rod 34, ensuring that the pull rod 34 always maintains linear movement during sliding, avoiding deviation or jamming, further improving the smoothness and accuracy of the pull rod 34's movement, thereby ensuring the normal operation of the entire automatic lock box mechanism.

[0041] Furthermore, in a preferred embodiment, the locking assembly 3 also includes two first limiting blocks 37 mounted on the support beam 1. The two first limiting blocks 37 are respectively located on the side where the two locking blocks 32 are close to each other. When the two locking blocks 32 are respectively in limiting contact with the two first limiting blocks 37, the two locking parts 321 are respectively longitudinally locked and limited with the two limiting steps 391. Specifically, the setting of the first limiting blocks 37 provides a clear definition of the locking position of the locking blocks 32, ensuring that the locking blocks 32 can accurately reach the locking position, so that the locking parts 321 and the limiting steps 391 can achieve reliable longitudinal locking and limiting, avoiding safety hazards caused by incomplete locking, and improving the accuracy and reliability of locking.

[0042] Furthermore, as a preferred embodiment, it also includes two second limiting blocks 38 installed on the support beam 1. The two second limiting blocks 38 are respectively located on the side of the two locking blocks 32 that are far apart from each other. When the two locking blocks 32 are respectively in limiting contact with the two second limiting blocks 38, the two locking parts 321 are respectively disengaged from the two limiting steps 391. Specifically, the setting of the second limiting blocks 38 clarifies the relaxed position of the locking blocks 32. When the locking blocks 32 are in contact with the second limiting blocks 38, it can ensure that the locking parts 321 are completely disengaged from the limiting steps 391, so that the container can be smoothly loaded and unloaded from the transfer vehicle or subjected to other operations, avoiding the normal movement of the container due to incomplete relaxation, and improving the convenience and safety of operation.

[0043] Furthermore, as a preferred embodiment, the locking part is a rolling bearing. Specifically, designing the limiting part as a rolling bearing can greatly reduce the friction between the locking part 321 and the limiting step 391, reduce component wear, and extend the service life of the equipment.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
