Description

Technical Field

[0001] This utility model relates to the field of garbage bin technology, and in particular to a garbage transfer vehicle. Background Technology

[0002] With the acceleration of urbanization, the number of permanent residents in large and medium-sized cities is increasing rapidly, and the corresponding amount of urban domestic waste is also increasing, thus placing higher demands on the processing capacity of waste transfer stations. The upgrading and renovation of transfer stations in various regions have presented new requirements: to upgrade as much advanced equipment as possible while minimizing costs, while ensuring compatibility with older equipment. This requires that the development of our sanitation equipment be both innovative and possess both advanced technology and excellent adaptability.

[0003] Existing garbage trucks use bottom positioning when placing garbage containers, which requires the rollers at the rear of the tipping frame to support the container on the ground. This requires a certain degree of flatness and slope of the ground. In addition, because the crossbeam at the rear of the tipping frame and the container unloading door are on the same vertical plane, garbage accumulates on the tail beam of the moving frame during unloading.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0054] See Figure 1 and Figure 13 This utility model provides a garbage transfer vehicle, comprising:

[0055] Subframe (1);

[0056] The rear of the tilting support mechanism and the subframe (1) are connected by a first pin, so that the tilting support mechanism can rotate around the first pin.

[0057] The lifting mechanism is connected at one end to the subframe (1) and is used to lift the tilting support mechanism so that the tilting support mechanism can be tilted from the horizontal position to the longitudinal position.

[0058] The front end of the flipping support mechanism is provided with a first locking member (23), and the rear end of the flipping support mechanism is provided with a second locking member (5);

[0059] When the flipping support mechanism is lifted to the longitudinal position, the second locking member (5) is used to limit the main beam on the garbage bin, and the first locking member (23) is used to lock with the corner piece at the top of the garbage bin.

[0060] The top positioning method is adopted, thereby reducing the requirements for the flatness and slope of the transfer station ground when carrying the box;

[0061] The tipping frame adopts a design without a rear crossbeam to avoid the phenomenon of garbage accumulating on the tail beam when the garbage bin is unloaded.

[0062] Furthermore, the tilting support mechanism includes:

[0063] The tilting frame (3) includes the second longitudinal tubes (31) on the left and right sides;

[0064] The movable frame (2) includes a front crossbeam (21) and first longitudinal tubes (22) on the left and right sides. The front crossbeam (21) is provided with a first locking element (23).

[0065] The first longitudinal tube (22) on the left side of the movable frame (2) passes through the second longitudinal tube (31) on the left side of the flipping frame (3), and the first longitudinal tube (22) on the right side of the movable frame (2) passes through the second longitudinal tube (31) on the right side of the flipping frame (3);

[0066] Translation cylinder (7), when the translation cylinder (7) is set on the left side, the translation cylinder (7) is connected to the first longitudinal tube (22) on the left side of the moving frame (2) and the second longitudinal tube (31) on the left side of the flipping frame (3);

[0067] When the translation cylinder (7) is set on the right side, the translation cylinder (7) is connected to the first longitudinal tube (22) on the right side of the moving frame (2) and the second longitudinal tube (31) on the right side of the tilting frame (3);

[0068] The translation cylinder (7) is used to realize the forward and backward translation of the moving frame (2) relative to the flipping frame (3);

[0069] The tail of the tilting frame (3) and the tail of the subframe (1) are connected by a first pin, and the tail of the tilting frame (3) is also provided with a second locking member (5).

[0070] The extension and retraction of the translation cylinder (7) enables the moving frame to move back and forth relative to the tilting frame;

[0071] The second locking component (5) can limit the trash can to the upper and lower limits and to the left and right limits to prevent the trash can from moving up, down, left, and right.

[0072] Through the design of the translation cylinder (7), the tipping frame (3), and the moving frame (2), during the process of lowering the garbage bin, the translation cylinder (7) is first used to pull the moving frame (2) back towards the tipping frame (3), so that the garbage bin moves towards the rear of the subframe and partially extends out of the rear of the subframe. Then, the lifting mechanism lifts the tipping support mechanism. When the tipping support mechanism flips around the first pin to the longitudinal position, the rear end of the garbage bin partially touches the ground before the longitudinal position. When the tipping support mechanism reaches the longitudinal position, the lower end of the rear end touches the ground. During the process of carrying the garbage bin, the tipping support mechanism gradually approaches and aligns with the garbage bin in the longitudinal position. The first and second locking parts lock the garbage bin. Then, the lifting mechanism lowers the tipping support mechanism, so that the tipping support mechanism flips around the first pin back to the horizontal position. At this time, the rear end of the garbage bin still extends beyond the rear of the subframe. The translation cylinder (7) pushes the moving frame forward towards the front of the vehicle. The forward movement of the moving frame drives the garbage bin forward, and the rear end of the garbage bin approaches the rear of the subframe.

[0073] Specifically, both the second longitudinal tube (31) and the first longitudinal tube (22) are rectangular tubes.

[0074] Furthermore, lifting mechanisms include:

[0075] The main lifting cylinder (8) is connected to the subframe (1) via a second pin, and the piston rod end of the main lifting cylinder (8) is connected to the tilting frame (3) via a third pin.

[0076] The auxiliary lifting mechanism (4) is used to lift the tilting support mechanism to an inclined position that forms an angle with the horizontal direction when the tilting support mechanism is in a horizontal position, and then the main lifting cylinder (8) continues to lift the tilting support mechanism from the inclined position to the longitudinal position.

[0077] The main lifting cylinder (8) is mounted on the subframe (1) and the tilting frame (3) by means of a pin. The tilting frame (3) and the moving frame (2) can rotate around the rear of the subframe (1) by means of extension and retraction of the main lifting cylinder (8).

[0078] The tilting support mechanism supports the garbage bin. Since the main lifting cylinder (8) is initially horizontal and is connected to the subframe and tilting frame respectively by pins, it is difficult for the main lifting cylinder (8) to directly lift the garbage bin. At this time, the tilting support mechanism is first lifted to a certain tilt angle by the auxiliary lifting mechanism. The auxiliary lifting mechanism gives the tilting support mechanism a certain lifting force. After the tilting support mechanism tilts to a certain degree, the main lifting cylinder can easily lift the tilting support mechanism to the longitudinal position.

[0079] Specifically, there is one main lifting cylinder (8) on each side.

[0080] After the auxiliary lifting mechanism (4) lifts the tilting support mechanism to a certain degree, the main lifting cylinder begins to lift the tilting support mechanism until it reaches the longitudinal position, and the auxiliary lifting mechanism (4) leaves the tilting frame.

[0081] Specifically, the auxiliary lifting mechanism (4) includes a swing arm, an auxiliary lifting cylinder, and a lifting seat;

[0082] The auxiliary lifting cylinder is mounted on the subframe (1), and the piston top of the auxiliary lifting cylinder is connected to the lifting seat; the first end of the swing rod is connected to the lifting seat, and the second end of the swing rod is connected to the first pin and rotates around the first pin.

[0083] During the lifting process of the tilting support mechanism, the piston of the auxiliary lifting cylinder lifts the lifting seat. Since the swing rod is connected to the lifting seat and the swing rod can rotate around the first pin, the first end of the swing rod rotates around the first pin, causing the lifting seat to also make an arc motion around the first pin, lifting the tilting support mechanism from the horizontal position to a certain tilt position.

[0084] Furthermore, the lifting mechanism has one main lifting cylinder on each side (8).

[0085] The two main lifting cylinders on the left and right sides achieve balanced and stable lifting and lowering of the tilting support frame.

[0086] See Figure 13 Furthermore, the front crossbeam (21) of the movable frame (2) has a first locking element (23) on each side.

[0087] Furthermore, the first locking element (23) is a rotary lock.

[0088] join Figure 10-12 Furthermore, the second locking element (5) is an automatic locking / unlocking mechanism, including:

[0089] The cylinder (51) has two winding shafts (52) symmetrically arranged on both sides. One end of each winding shaft (52) is connected to one telescopic end of the cylinder (51). The other end of each winding shaft (52) is provided with a guide plate (53). The cylinder (51) drives the winding shaft (52) to extend and retract, thereby driving the guide plate (53) to move back and forth to lock and unlock the connecting frame of the garbage bin.

[0090] The specific structure of the automatic locking and unlocking mechanism is as described in patent application CN202321751754.1, which discloses an automatic locking and unlocking mechanism for a transfer box. The connecting frame of the garbage box is an L-shaped structure, which consists of a first section and a second section that are perpendicular to each other. The winding shaft (52) is also provided with an annular limiting boss (55), and the first section of the two L-shaped structures of the garbage box is limited to the left and right by the annular limiting boss (55) on the two winding shafts (52) of the automatic locking and unlocking mechanism. The guide plate (53) is provided with a limiting roller (54), and the second section of the L-shaped structure extends into the lower part of the limiting roller (54) above the winding shaft (52). The winding shaft (52) and the limiting roller (54) limit it vertically. The automatic locking and unlocking mechanism locks the garbage box, but the garbage can slide back and forth relative to the automatic locking and unlocking mechanism in the direction of the front and rear of the vehicle. The winding shaft is used to lock and unlock the box, which improves the degree of automation.

[0091] Furthermore, it also includes:

[0092] The vehicle chassis (6), the main beam of the vehicle chassis and the subframe (1) are connected by bolts through connecting plates.

[0093] See Figure 2-4 During the garbage truck's container placement process, firstly, the piston of the translation cylinder (7) retracts, causing the moving frame to move towards the rear of the vehicle. Because the first locking piece (23) is locked to the garbage container, the garbage container also moves backward. Then, the auxiliary lifting mechanism partially lifts the flipping support mechanism and rotates it around the first pin shaft, gradually lifting the garbage container backward. The main lifting cylinder continues to lift the garbage container, and the bottom of the garbage container gradually touches the ground. After the main lifting cylinder lifts the flipping support mechanism and flips it to the longitudinal position, the garbage container stands vertically on the ground. Then, the first and second locking pieces are unlocked, causing the flipping support mechanism and the garbage container to separate. The container placement process is completed, and the vehicle drives away.

[0094] See Figure 5-8 During the process of transporting the garbage truck to the back of the garbage container, firstly, the vehicle gradually approaches and aligns with the garbage container, then reverses. As it approaches the garbage container, the second locking piece can press against the main beam of the garbage container, i.e., the connecting frame, so that the longitudinal center of the garbage container coincides with the longitudinal center of the garbage truck. Then, the first locking piece and the corner piece at the top of the garbage container are locked. After that, the main lifting cylinder descends, and the tilting support mechanism gradually tilts and lowers the garbage container from the longitudinal position to the horizontal position. After reaching the horizontal position, the piston of the translation cylinder (7) extends, moving the moving frame towards the front of the garbage truck. The garbage container also moves towards the front of the truck, and the rear of the garbage container is gradually retracted into the garbage truck.

[0095] See Figure 9This diagram illustrates the unloading process of a garbage truck's container. The truck's tilting support mechanism is tilted to a specific angle, such as the unloading angle. The unloading door is opened via a quick-connect connector at the rear and by operating a corresponding switch in the driver's cab, initiating unloading. Once unloading is complete, the unloading door is closed, the quick-connect connector is removed, and the vehicle drives away. Unloading via the quick-connect connector at the rear is existing technology and will not be elaborated upon here. This invention eliminates the reliance on the ground surface during container loading and unloading, and also addresses the issue of garbage accumulation at the rear during unloading. Furthermore, the automatic locking and unlocking mechanism of the rear winding shaft enhances the automation of the entire process.

[0096] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any 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.
