Description

Technical Field

[0001] This application relates to the field of sanitation equipment technology, and in particular to a tipping bucket connection assembly and a garbage truck. Background Technology

[0002] Garbage trucks are the core equipment of the urban sanitation system, undertaking key functions such as garbage collection, compression, and transportation. The tipping mechanism is the core component for realizing automated garbage collection. It mainly uses a hydraulic system to lift and tip the garbage bins to dump the garbage into the truck compartment.

[0003] The lifting mechanism of the bucket tipping mechanism is mainly achieved by the rotation of the lifting arm relative to the support frame. The contact surface of the rotating pair between the lifting arm and the support frame is lubricated by the bushing. The bushing is a wear part. When the wear exceeds a certain range, it will affect the working stability of the feeding mechanism and increase the noise. It needs to be replaced in time.

[0004] However, the current lifting arm adopts an integrated design, which has good overall integrity and strong stability during operation. However, since the lifting arm is the main support and drive component of the bucket tipping mechanism, it is heavy. The rotating sleeve is fitted into the long holes on both sides of the lifting arm, which are deep and thin. When replacing the rotating sleeve, special lifting tools are required to disassemble the lifting arm, remove the pins on the support frame, and then take out the rotating sleeve from the long holes on both sides of the lifting arm for replacement. Removing the rotating sleeve is difficult and cannot be done manually, which is labor-intensive, material-intensive, and costly. Utility Model Content

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0049] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] like Figure 1 As shown, in the prior art, an integral round tube is set on the lifting arm 100, which runs horizontally through the entire lifting arm 100. In this way, bushings 300 can be installed in the elongated holes on both sides of the lifting arm 100, so that the pins 400 on the support frame 200 can be inserted into the two bushings 300 from both sides to achieve a rotatable connection between the lifting arm 100 and the support frame 200.

[0051] When disassembling the bushing 300, a special lifting tool is needed to lift the lifting arm 100, and then the pins 400 on both sides are disassembled. After the entire lifting arm 100 is disassembled, the rotating sleeve is taken out from the long holes on both sides. The rotating sleeve is difficult to remove and cannot be done by manpower alone, which consumes manpower and resources and is costly.

[0052] To address the aforementioned issues, the inventors developed a tipping bucket connection assembly that allows for the replacement of the two side sleeves by a single person without the need for specialized lifting equipment, saving manpower and resources and reducing costs.

[0053] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] This application discloses a tipping bucket connection assembly, which is mainly used in garbage trucks and serves to install tipping buckets on the garbage truck and lift the tipping buckets.

[0055] In the embodiments of this application, combined with Figures 2 to 5 The tipping bucket connection assembly includes a lifting arm 100 and a support frame 200. One of the support frame 200 and the lifting arm 100 is fitted with a removable sleeve 600, and the other is connected to a shaft 500. That is, the support frame 200 can be fitted with the removable sleeve 600, and the corresponding lifting arm 100 can be connected to the shaft 500; alternatively, the support frame 200 can be connected to the shaft 500, and the corresponding lifting arm 100 can be fitted with the removable sleeve 600. A bushing 300 is fixed inside the removable sleeve 600, and the shaft 500 is rotatably inserted into the bushing 300.

[0056] In this way, by connecting the insert shaft 500 to the support frame 200 or the lifting arm 100, installing the detachable sleeve 600 onto the lifting arm 100 or the support frame 200, and then rotatably inserting the insert shaft 500 into the bushing 300 fixed inside the detachable sleeve 600, the connection between the lifting arm 100 and the support frame 200 is achieved. When it is necessary to remove the bushing 300, simply remove the removable sleeve 600 on one side from the lifting arm 100 or the support frame 200, remove the bushing 300 inside the removable sleeve 600, replace it with a new bushing 300, and then reinstall the removable sleeve 600 onto the lifting arm 100 or the support frame 200. Then, repeat the process of removing the removable sleeve 600 on the other side, replacing the bushing 300, and reinstalling it. This process can replace the bushings 300 on both sides. Throughout the replacement process, one side of the lifting arm 100 is always connected to the support frame 200 through the removable sleeve 600 and the insert shaft. Therefore, it is not necessary to use special lifting tools to lift the lifting arm 100, which increases the maintainability of the product. The replacement of the bushing 300 can be completed by a single person, saving manpower and resources and reducing costs.

[0057] Optionally, in order to limit the axial lateral movement of the lifting arm 100, a first step 530 is formed on the insert shaft 500, which is opposite to the removable sleeve 600.

[0058] For example, the insert shaft 500 includes a fixed portion 510 and an extended shaft portion 520 that are relatively fixed. The outer diameter of the extended shaft portion 520 is smaller than the outer diameter of the fixed portion 510, so that a first step 530 is formed between the extended shaft portion 520 and the fixed portion 510. The first step 530 is an annular area on the end face of the fixed portion 510 that is not covered by the extended shaft portion 520. The fixed portion 510 is connected to the lifting arm 100 or the support frame 200, and the end face of the fixed portion 510 is opposite to the end face of the removable sleeve 600. At least a portion of the extended shaft portion 520 protrudes from the end face of the fixed portion 510 near the removable sleeve 600, and the portion of the extended shaft portion 520 protruding from the fixed portion 510 is rotatably inserted into the bushing 300.

[0059] Thus, by designing the insert shaft 500 as a stepped structure consisting of the protruding shaft portion 520 and the fixing portion 510, the axial lateral movement of the entire lifting arm 100 is restricted by the end face contact between the detachable sleeve 600 and the fixing portion 510, thereby achieving a limiting function.

[0060] Of course, in some embodiments, the first step 530 can also be formed as a convex ring on an optical axis by welding or integral molding.

[0061] In detail, Figure 2 and Figure 3 In the embodiment shown where the insert shaft 500 is connected to the lifting arm 100, the insert shaft 500 can be an integral stepped shaft, that is, the protruding shaft portion 520 is integrally connected to the end of the fixing portion 510, and the fixing portion 510 is connected to the lifting arm 100, reducing the number of parts.

[0062] Among them, the insert shaft 500 can be integrally formed with the lifting arm 100, that is, the fixing part 510 is integrally connected with the lifting arm 100. In this way, the lifting arm 100 still adopts an integrated design. The extended shaft parts 520 on both sides are inserted into the internal bushing 300 of the detachable sleeve 600 and connected to the support frame 200, thereby ensuring the stability and reliability of the bucket tipping mechanism.

[0063] The support frame 200 is provided with an assembly hole 210, and the detachable sleeve 600 passes through the assembly hole 210. The end of the detachable sleeve 600 away from the fixing part 510 is detachably connected to the support frame 200 so as to facilitate the removal of the detachable sleeve 600 from the outside of the support frame 200.

[0064] The removable sleeve 600 has a first flange ring 610. Specifically, the removable sleeve 600 has an integral first flange ring 610 at the end away from the fixed part 510. The first flange ring 610 is connected to the support frame 200 by bolts, thereby installing the removable sleeve 600 onto the support frame 200.

[0065] Since the lifting arm 100 is far from the support frame 200 on both sides, the inner hole of the removable sleeve 600 can be designed as a stepped hole to accurately position the shorter bushing 300. Specifically, the inner hole of the removable sleeve 600 includes a first hole segment 620 and a second hole segment 630 connected in sequence. The first hole segment 620 is closer to the first step 530 than the second hole segment 630, and the inner diameter of the first hole segment 620 is larger than the inner diameter of the second hole segment 630. A second step 650 is formed between the first hole segment 620 and the second hole segment 630. The bushing 300 is fixed in the first hole segment 620, for example, by a tight fit. One end of the bushing 300 abuts against the second step 650, which serves as a positioning function, limits the position of the bushing 300, ensures sufficient contact area between the bushing 300 and the protruding shaft 520, and facilitates the installation of the bushing 300 in place during the process of inserting it into the removable sleeve 600. In addition, even if the bushing 300 comes loose, the two ends of the bushing 300 are limited by the second step 650 and the end face of the fixing part 510, respectively, which can play a role in limiting and preventing it from coming loose.

[0066] Of course, in some embodiments, the insert shaft 500 can also be fixed to the lifting arm 100 by a separate connection. For example, the insert shaft 500 is an integral stepped shaft structure, the lifting arm 100 is provided with a through hole, the insert shaft 500 passes through the through hole, and both ends of the insert shaft 500 extend out of the side of the lifting arm 100 and are inserted into the detachable sleeve 600 installed on the support frame 200. The insert shaft 500 and the lifting arm 100 can be fixedly connected by welding or other methods, thus achieving a fixed connection between the insert shaft 500 and the lifting arm 100.

[0067] In addition, the inner hole of the removable sleeve 600 can also be a smooth hole with a constant diameter. The bushing 300 has a flange extending radially outward at one end. The flange and the end face of the removable sleeve 600 can also play a role in limiting and preventing disengagement.

[0068] In such Figure 4 In the embodiment where the insert shaft 500 is connected to the support frame 200, the insert shaft 500 has a split structure. For example, the fixing part 510 is connected to the support frame 200 and has a sleeve-like structure. The length of the protruding shaft part 520 is greater than the length of the fixing part 510. The protruding shaft part 520 passes through the fixing part 510 and is connected to the support frame 200. In this way, the fixing part 510 increases the support area of ​​the protruding shaft part 520, improving the connection reliability of the protruding shaft part 520 relative to the support frame 200. At the same time, the end face of the fixing part 510 near the lifting arm 100 serves as a first step 530.

[0069] The fixing part 510 can be fixedly connected to the support frame 200 by welding. The protruding shaft part 520 has a third flange ring 521. Specifically, the end of the protruding shaft part 520 away from the detachable sleeve 600 has an integrally formed third flange ring 521. The third flange ring 521 is connected to the support frame 200 by bolts to fix the protruding shaft part 520 relative to the support frame 200.

[0070] The lifting arm 100 has a mounting hole 110, and a removable sleeve 600 passes through the mounting hole 110. The end of the removable sleeve 600 away from the fixing part 510 is detachably connected to the lifting arm 100, which makes it convenient to remove the removable sleeve 600 from the middle break of the lifting arm 100.

[0071] The removable sleeve 600 has a second flange ring 640. Specifically, the removable sleeve 600 has an integrally formed second flange ring 640 at the end away from the fixed part 510. The second flange ring 640 is connected to the lifting arm 100 by bolts to achieve the fixation of the removable sleeve 600 relative to the lifting arm 100.

[0072] In this embodiment, due to the width limitation of the lifting arm 100, two detachable sleeves 600 need to be installed on the lifting arm 100 to cooperate with the insert shafts 500 on both sides respectively. Therefore, the length of the detachable sleeves 600 is relatively short, and there is a certain gap between the two detachable sleeves 600. At this time, the inner hole of the detachable sleeve 600 can be designed as a smooth hole with a constant diameter. The length of the bushing 300 can also be the same as the length of the detachable sleeve 600. In this way, during the installation of the bushing 300, the two ends of the bushing 300 can be flush with the two ends of the detachable sleeve 600 to ensure that the installation is in place.

[0073] Of course, in some embodiments, if the width of the lifting arm 100 is sufficient, it is feasible to design the length of the removable sleeve 600 to be greater than the length of the bushing 300. In this case, the inner hole of the removable sleeve 600 can also be designed as follows: Figure 3 The stepped hole in the embodiment.

[0074] It should also be noted that, in Figure 5 In some embodiments shown, if the lateral width space on the support frame 200 for mounting the lifting arm 100 is limited, the insert shaft 500 can be designed as a split structure to improve structural compactness, and the fixing part 510 is a sleeve-shaped structure. The fixing part 510 is fixedly connected to the lifting arm 100. The length of the protruding shaft part 520 is greater than the length of the fixing part 510. The protruding shaft part 520 passes through the fixing part 510 and is fixed relative to the fixing part 510. In this way, both ends of the protruding shaft part 520 can extend from both ends of the fixing part 510 and extend into the bushing 300 fixed in the detachable sleeve 600 mounted on the support frame 200. At this time, the end face of the fixing part 510 near the support frame 200 serves as the first step 530.

[0075] The fixing part 510 is integrally connected to the lifting arm 100 to improve structural strength. Of course, the fixing part 510 can also be separately connected to the lifting arm 100. For example, the lifting arm 100 can be provided with through holes for the fixing part 510 to pass through and then fixedly connected by welding or other methods.

[0076] To secure the protruding shaft portion 520 relative to the fixed portion 510, a locking pin 700 can be used, which passes radially through the insert shaft 500 into both the fixed portion 510 and the protruding shaft portion. Specifically, the fixed portion 510 has a radially penetrating first locking hole 511, and the protruding shaft portion 520 has a radially penetrating second locking hole 522. The locking pin 700 passes through the first locking hole 511 and the second locking hole 522 to lock the protruding shaft portion 520.

[0077] The connection method between the detachable sleeve 600 and the support frame 200 and Figure 3 The structures shown are the same, so they will not be described again.

[0078] In addition, this application also discloses a garbage truck, which includes the tipping bucket connecting assembly of the above embodiments, and therefore also has the corresponding structure and beneficial effects, which will not be described in detail here.

[0079] In summary, this application discloses a tipping bucket connection assembly and a garbage truck. By connecting the insert shaft 500 to the support frame 200 or the lifting arm 100, and installing the detachable sleeve 600 onto the lifting arm 100 or the support frame 200, the insert shaft 500 is rotatably inserted into the bushing 300 fixed within the detachable sleeve 600. When it is necessary to remove the bushing 300, simply detach one side of the detachable sleeve 600 from the lifting arm 100 or the support frame 200, remove the bushing 300 inside the detachable sleeve 600, and replace it with a new bushing 300. Then, the removable sleeve 600 is reinstalled onto the lifting arm 100 or the support frame 200. Then, the removable sleeve 600 on the other side is removed, the bushing 300 is replaced, and then reinstalled. This process can replace the bushings 300 on both sides. Throughout the replacement process, one side of the lifting arm 100 is always connected to the support frame 200 through the removable sleeve 600 and the insert shaft. Therefore, it is not necessary to use special lifting tools to lift the lifting arm 100, which increases the maintainability of the product. The replacement of the bushing 300 can be completed by a single person, saving manpower and resources and reducing costs.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
