[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.
[0041] In addition, the described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations or operations are not shown or described in detail to avoid blurring various aspects of the present disclosure.
[0042] The present disclosure is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.
[0043] like Figures 1 to 4 As shown, an embodiment of the present disclosure provides a gripping mechanism 1 , comprising a base weld 11 , a gripping assembly 12 and a material guide plate 13 .
[0044] Among them, such as Figure 1 As shown in Figures 2 and 3, the grabbing assembly 12 is arranged on the base weld 11; the grabbing assembly 12 includes two grabbing arms 121, one end of the two grabbing arms 121 is movably connected to the base weld 11, and the other end can move closer to or farther away from each other to grab the trash can 2 or put down the trash can 2.
[0045] It should be noted that the two gripping arms 121 in the gripping assembly 12 can be symmetrically arranged about the central axis of the base weld 11 .
[0046] Furthermore, the gripping arm 121 may include a master arm 1211 and a slave arm 1212. The master arm 1211 is movably connected to the base weld 11 via a rotating shaft, so that the master arm 1211 can rotate around the base weld 11. The non-end portion of the slave arm 1212 is movably connected to the master arm 1211 via the rotating shaft, and the slave arm 1212 can rotate around the master arm 1211. The slave arm 1212 in the present disclosure may be an integrally formed part, thereby simplifying the manufacturing and connection process of the slave arm 1212.
[0047] In the embodiment of the present disclosure, the driven arm 1212 can rotate synchronously around the base weld 11 under the drive of the active arm 1211. When the active arms 1211 on the two grabbing arms 121 approach each other, the driven arms 1212 on the two grabbing arms 121 also approach each other, so that the two grabbing arms 121 can grab the trash can 2.
[0048] In addition, the gripping assembly 12 in the embodiment of the present disclosure may also include two connecting rod parts 122 and a bucket holding cylinder 124, which are symmetrically arranged about the central axis of the base weld 11. One end of the connecting rod part 122 is movably connected to the base weld 11, and the other end is movably connected to the driven arm 1212. The bucket holding cylinder 124 is arranged in the base weld 11, thereby reducing the space occupied by the gripping assembly 12. One end of the bucket holding cylinder 124 is fixedly connected to the base weld 11, and the other end is movably connected to the active arm 1211, wherein the bucket holding cylinder 124 can provide kinetic energy for the movement of the gripping arm 121 to grab and put down the trash can 2.
[0049] Specifically, the base weld 11, the active arm 1211, the driven arm 1212 and the connecting rod assembly 122 in the embodiment of the present disclosure together form a four-bar linkage mechanism. Driven by the bucket holding cylinder 124, the active arm 1211 moves around the base weld 11, thereby driving the driven arm 1212 and the connecting rod assembly 122 to move together, and then the two grabbing arms 121 can be moved closer to each other to grab the trash can 2, and the two grabbing arms 121 can be moved away from each other to put down the trash can 2.
[0050] In the disclosed embodiment, the gripping assembly 12 may further include two gripping straps 123, one end of each gripping strap 123 being connected to the base weld 11, and the other end being connected to the end of the driven arm 1212 away from the connecting rod 122. The gripping straps 123, the base weld 11, and the driven arm 1212 may be connected by bolts. When the driven arm 1212 rotates around the base weld 11, the gripping straps 123 move along with the driven arm 1212. When the trash can 2 is gripped, the side of the gripping straps 123 facing away from the driven arm 1212 abuts against the outer wall of the trash can 2. The provision of the gripping straps 123 increases the contact area between the gripping assembly 12 and the trash can 2 when gripping the trash can 2, thereby increasing friction and reducing the possibility of the trash can 2 slipping off the two gripping arms 121.
[0051] For example, the gripping strap 123 in the disclosed embodiment can be made of a combination of woven fabric and rubber. The rubber material can be a special rubber with excellent friction, tensile strength, anti-aging, and acid and alkali resistance, thereby reducing the risk of damage to the gripping strap 123 and extending its service life.
[0052] It should be noted that, since there is currently no fixed national standard for plastic trash cans 2 in China, trash cans 2 vary in size and shape. To expand the applicability of the gripping mechanism 1, the disclosed embodiment can control the rotation angle of the two gripping arms 121 to enable the gripping mechanism 1 to grip trash cans 2 of various sizes (e.g., 120L, 240L, etc.) and shapes (circular, rectangular, etc.). Furthermore, the disclosed embodiment provides a gripping belt 123 to enable the gripping mechanism 1 to effectively grip trash cans 2 of varying sizes and shapes, thereby improving the efficiency of the gripping mechanism 1 and expanding its application scenarios.
[0053] In addition, the entire process from grabbing the trash can 2, to dumping the garbage, and then putting the trash can 2 back to its original position can be controlled by the driver sitting in the car through a program. This avoids a large amount of manpower input in the operation of collecting the trash can 2, reduces the labor intensity of the workers, and improves the efficiency of the operation of collecting the trash can 2.
[0054] The gripping assembly 12 in the embodiment of the present disclosure can be connected to the flipping mechanism in the sanitation vehicle. Specifically, the flipping mechanism can be connected to the top of the base weld 11 through a rotating shaft, so that the gripping assembly 12 can be lifted and lowered and flipped while the flipping mechanism is flipping. When the gripping assembly 12 grabs the correct position on the trash can 2 and the gripping assembly 12 rises to above the filling hopper in the sanitation vehicle under the drive of the flipping mechanism, the rotating shaft is rotated to tilt the open end of the trash can 2 toward the filling hopper, and then the open end can be aligned with the top of the filling hopper, so that the garbage can enter the filling hopper smoothly, thereby reducing the risk of garbage leakage when dumping the garbage.
[0055] It should be noted that the aforementioned correct position on the trash can 2 grasped by the gripping assembly 12 is such that the open end of the sanitation vehicle is positioned directly above the filling hopper when dumping the trash. For example, the correct position on the trash can 2 grasped by the gripping assembly 12 may be at the height center of the trash can 2, but this is not limited to this. The correct position on the trash can 2 grasped by the gripping assembly 12 may be determined based on actual circumstances.
[0056] Since the gripping position of the gripping assembly 12 may be different each time it grips the trash can 2, when the gripping assembly 12 does not grip the correct position on the trash can 2, there may be a certain distance between the open end of the trash can 2 and the top of the filling hopper when dumping the trash, which may cause the trash to leak out.
[0057] To avoid the above situation, if Figures 3 and 4As shown, in the embodiment of the present disclosure, a guide plate 13 is provided in the gripping mechanism 1. The guide plate 13 is located above the base weld 11. The guide plate 13 has a guide surface that faces the trash can 2 gripped by the gripping assembly 12. When the gripping assembly 12 is not gripped in the correct position on the trash can 2, and there is a certain distance between the open end of the trash can 2 and the area directly above the filling hopper during the process of dumping the trash, the guide plate 13 protrudes from the open end of the trash can 2 in the height direction. When dumping the trash, the guide plate 13 can guide the trash in the trash can 2 into the filling hopper, thereby reducing the possibility of the trash falling outside the filling hopper.
[0058] In addition, the guide plate 13 can also be used as a height reference when the gripping assembly 12 grabs the trash can 2. For example, when grabbing the trash can 2, it is possible to avoid the side of the guide plate 13 close to the base weld 11 being higher than the opening end of the trash can 2, thereby reducing the situation where the guide plate 13 cannot guide the garbage into the filling hopper when the opening end of the trash can 2 is too far away from the filling hopper, thereby reducing the risk of garbage leakage.
[0059] In the disclosed embodiment, the guiding surface of the guide plate 13 can be a vertical surface parallel to the vertical direction, but is not limited thereto. The top of the guiding surface can also be an inclined surface inclined at a certain angle away from the trash can 2, which can be determined according to actual conditions.
[0060] For example, when the diameter of the trash can 2 increases from bottom to top, the outer wall of the trash can 2 is tilted relative to the vertical direction. At this time, the guide surface can be set as an inclined surface, and the angle between the guide surface and the vertical direction is equal to the angle between the trash can 2 and the vertical direction. In this way, the connection inside the trash can 2 can slide along the guide surface into the filling hopper under the action of gravity, so that the garbage can be smoothly dumped into the filling hopper.
[0061] The guide plate 13 can be made of elastic steel. By providing a certain degree of rigidity, the guide plate 13 can provide support for the trash can 2 during the dumping process, thereby preventing the trash can 2 from tipping over beyond its maximum limit and damaging the gripper assembly 12. Furthermore, by providing a certain degree of elasticity, the guide plate 13 can automatically recover after being deformed by pressure.
[0062] In the disclosed embodiment, a buffer member 14 can be provided on the guide plate 13. The buffer member 14 is disposed on the guide surface and is elastic. Positioned between the trash can 2 and the guide plate 13, the buffer member 14 can reduce the impact force between the trash can 2 and the guide plate 13, thereby reducing the risk of damage to the trash can 2 and the guide plate 13. Specifically, the buffer member 14 in the disclosed embodiment can be made of rubber, but is not limited to this. Other elastic materials can also be used to make the buffer member 14 in the disclosed embodiment.
[0063] In addition, the present disclosure may also provide a mounting bracket 15 between the guide plate 13 and the base weld 11. The mounting bracket 15 is attached to the side of the guide plate 13 facing away from the guide surface and is detachably connected to the guide plate 13. The mounting bracket 15 is also detachably connected to the base weld 11. The provision of the mounting bracket 15 in the disclosed embodiment can alleviate the stress concentration problem at the connection between the guide plate 13 and the base weld 11, and can also enhance the overall structural strength of the guide plate 13, thereby improving the support performance of the guide plate 13 for the trash can 2. By detachably connecting the mounting bracket 15 to the base weld 11 and the guide plate 13, the disclosed embodiment facilitates the maintenance and replacement of the guide plate 13 and the mounting bracket 15, thereby reducing maintenance time for the gripping mechanism 1.
[0064] In the embodiment of the present disclosure, the grabbing mechanism 1 may include a buffer structure 16, which is arranged at the front of the base weld 11 and connected to the base weld 11 by bolts, wherein the front of the base weld 11 is located on the side of the base weld 11 close to the trash can 2 grabbed by the gripping assembly 12, and when grabbing the trash can 2, the buffer structure 16 is located between the base weld 11 and the trash can 2.
[0065] Among them, the buffer structure 16 has a certain elasticity. The buffer structure 16 can be set on the side of the guide plate 13 close to the base weld 11, and the side of the buffer structure 16 facing the trash can 2 can be protruded from the guide surface. When grabbing the trash can 2, the trash can 2 abuts against the buffer structure 16, which can reduce the risk of severe impact between the trash can 2 and the base weld 11, thereby reducing the possibility of damage to the trash can 2 and the base weld 11, so as to extend the service life of the trash can 2 and the base weld 11.
[0066] In the disclosed embodiment, the gripping mechanism 1 may further include a position sensor 17 , which is located in the base weld 11 and is used to sense the position of the gripping arm 121 at the base weld 11 in real time.
[0067] For example, the position sensor 17 can be used to detect the position of the active arm 1211 on the base weld 11. When the two active arms 1211 approach each other and grab the trash can 2, the gripping arm 121 is in a fully closed state, and the active arm 1211 moves to the bottom of the position sensor 17. At this time, the position sensor 17 can send a signal that the gripping arm 121 is closed; when the two active arms 1211 move away from each other and put down the trash can 2 they have grabbed, the gripping arm 121 is in an open state, and the active arm 1211 leaves from directly below the position sensor 17. When the distance between the active arm 1211 and the position sensor 17 exceeds a set value, the signal of the position sensor 17 is lost, that is, the present disclosure can judge the position of the gripping arm 121 at the base weld 11 through the detection result feedback from the position sensor 17, thereby facilitating the automation of the operation of the gripping assembly 12 grabbing or putting down the trash can 2, while reducing the labor intensity of the staff, and improving the working efficiency of the gripping mechanism 1.
[0068] The present disclosure provides a sanitation vehicle comprising a vehicle body and any of the aforementioned gripping mechanisms 1, with a base welded to the vehicle body 11. The gripping mechanism 1 can be disposed on a side of the vehicle body and can be moved relative to the vehicle body. The gripping mechanism 1 can be moved to the location of a trash can 2 to thereby grip the trash can 2.
