[0057] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.
[0058] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the
[0059] The disclosure will be described in further detail below with reference to the drawings and specific embodiments. It is to be noted that technical features involved in each of the embodiments of the disclosure described below can be combined if not in conflict. The embodiments described below by reference to the drawings are exemplary and are intended to explain the disclosure and should not be understood as limiting the disclosure.
[0060] As Figures 1 to 3As shown, the present disclosure provides a turnover mechanism 1, which comprises a base weld 11, two swing oil cylinders 12 located on the top of the base weld 11, and a turnover arm 13, the two swing oil cylinders 12 are symmetrically arranged about the base weld 11 and are fixedly connected with the base weld 11.
[0061] It should be noted that the swing oil cylinder 12 in the present disclosure can adopt a rack swing oil cylinder 12, and the base weld 11 and the swing oil cylinder 12 can be fixedly connected by bolts.
[0062] The turnover arm 13 is located on the symmetry axis of the two swing oil cylinders 12. The turnover arm 13 comprises a first end and a second end, which respectively refer to the two ends of the length direction of the turnover arm 13. The first end of the turnover arm 13 is rotatably connected with the two swing oil cylinders 12, and the second end of the turnover arm 13 is used for rotatably connecting with the bucket holding mechanism 2. Among them, the second end of the turnover arm 13 can rotate around its first end, so that the second end of the turnover arm 13 can be rotated at least above its first end.
[0063] Specifically, the first end of the turnover arm 13 can be connected with the two swing oil cylinders 12 through involute spline, the number of teeth of the involute spline is large, which can realize automatic centering, so that the turnover arm 13 can keep coaxial and synchronous rotation with the swing oil cylinder 12 through the involute spline. Most of the teeth in the involute spline work at the same time, which can not only improve the stability of the turnover arm 13 when it is turned with the swing oil cylinder 12, but also can reduce the bending stress and contact extrusion stress of the involute spline under load, thereby enhancing the stability of the connection between the turnover arm 13 and the swing oil cylinder 12, reducing the maintenance cost of the turnover mechanism 1, and improving the market competitiveness of the turnover mechanism 1. In addition, the coupling size of the involute spline is small, so that the turnover mechanism 1 can occupy smaller space under the same load working condition. However, the first end of the turnover arm 13 can also be connected with the two swing oil cylinders 12 through double keys, rectangular splines and other connecting parts, which can be set according to actual conditions.
[0064] In addition, the second end of the turnover arm 13 can be rotatably connected with the bucket holding mechanism 2 through a rotating shaft 131, so that the bucket holding mechanism 2 can be lifted up and down under the driving of the turnover arm 13, and the turnover of the bucket holding mechanism 2 can also be realized through the rotating shaft 131.
[0065] This embodiment of the invention improves the rotational capacity of the second end of the tilting arm 13 around its first end by symmetrically spaced two swing cylinders 12 on the top of the base weld 11. This avoids insufficient power provided by a single swing cylinder 12, which could prevent the tilting arm 13 from failing to tilt, thus ensuring the normal operation of the tilting mechanism 1. The invention also simplifies the structure of the tilting arm 13 by arranging it on the axis of symmetry of the two swing cylinders 12, reducing the space occupied by the tilting arm 13. Furthermore, the two swing cylinders 12 are located on opposite sides of the tilting arm 13, facilitating their installation, removal, and maintenance, thereby reducing the difficulty of these processes.
[0066] In one embodiment of this disclosure, the tilting mechanism 1 may further include two connecting rod assemblies 14. The two connecting rod assemblies 14 and the swing cylinder 12 are located on the same side of the base welded 11, and the two connecting rod assemblies 14 are symmetrically distributed about the tilting arm 13. The first rotating end of the connecting rod assembly 14 is rotatably connected to the base welded 11, and the second rotating end of the connecting rod assembly 14 is rotatably connected to the bucket holding mechanism 2. When the tilting arm 13 tilts, the second rotating end of the connecting rod assembly 14 tilts around its first rotating end, thereby driving the bucket holding mechanism 2 to achieve vertical lifting and lowering.
[0067] It should be noted that in this embodiment, the base welding 11, the tilting arm 13, the bucket holding mechanism 2 and the connecting rod assembly 14 together form a four-bar linkage mechanism. When the swing cylinder 12 rotates, it drives the tilting arm 13 to rotate. Under the constraint of the connecting rod assembly 14, the bucket holding mechanism 2 rotates along the tilting arm 13 along a fixed trajectory, thereby realizing the lifting and lowering action of the bucket holding mechanism 2.
[0068] like Figure 3 As shown, in one embodiment of this disclosure, the flipping mechanism 1 may further include a first position sensor 15, which is fixed to the base weld 11 and located between the base weld 11 and the flipping arm 13, for detecting the position of the flipping arm 13.
[0069] The first position sensor 15 can be fixed to the base weld 11 with bolts, but it is not limited to this. The first position sensor 15 can also be fixed to the base weld 11 in other ways than bolts. This disclosure provides real-time feedback on the position of the tilting arm 13 by setting the first position sensor 15. Then, the operation of each component in the tilting mechanism 1 can be controlled according to the feedback result of the first position sensor 15, so as to improve the stability, accuracy and efficiency of the tilting mechanism 1 and realize the full automation of the lifting and tilting of the tilting mechanism 1.
[0070] In the embodiments of the present disclosure, the turnover mechanism 1 can include a first buffering structure 16 fixed to the top surface of the base weld 11, and when the turnover arm 13 is turned up to the top surface of the base weld 11, the turnover arm 13 abuts against the first buffering structure 16.
[0071] It should be noted that the first buffering structure 16 in the embodiments of the present disclosure can be used to limit the turnover arm 13 and achieve buffering and damping between the turnover arm 13 and the top of the base weld 11, so as to avoid the possibility that the turnover arm 13 exceeds the maximum turning angle when turned up, and then causes the collision between the turnover arm 13 and the base weld 11, thereby reducing the risk of damage to the turnover arm 13 and the base weld 11, prolonging the service life of the turnover arm 13 and the base weld 11, reducing the maintenance cost of the turnover mechanism 1, and ensuring the smooth operation of the turnover mechanism 1.
[0072] In the embodiments of the present disclosure, the maximum turning angle refers to the maximum angle of the turnover arm 13 turned up in the setting program. For example, the maximum turning angle in the embodiments of the present disclosure can be 180°, but is not limited thereto, and the value of the maximum turning angle can be determined according to actual conditions.
[0073] In the embodiments of the present disclosure, the turnover mechanism 1 can include a second buffering structure arranged on the side of the base weld 11 facing the swing oil cylinder 12, and when the turnover arm 13 moves down to the initial position, the turnover arm 13 abuts against the second buffering structure.
[0074] It should be noted that the initial position refers to the position of the second end of the turnover arm 13 located directly below the first end thereof. When the turnover arm 13 is turned down, the turnover arm 13 can collide with the base weld 11 under the action of gravity and the swing oil cylinder 12, thereby possibly causing damage to the base weld 11 and the swing oil cylinder 12. In order to avoid the above situation, the present disclosure provides the second buffering structure arranged on the side of the base weld 11 facing the turnover arm 13, so as to achieve buffering between the turnover arm 13 and the base weld 11 when turned down, thereby reducing the risk of damage to the turnover arm 13 and the base weld 11, prolonging the service life of the turnover arm 13 and the base weld 11, and reducing the maintenance cost of the turnover mechanism 1.
[0075] For example, the first buffering structure 16 and the second buffering structure in the embodiments of the present disclosure can be made of rubber and polyethylene, but are not limited thereto, and other materials that can facilitate buffering between the turnover arm 13 and the base weld 11 can be used to make the first buffering structure 16 and the second buffering structure, which can be included in the embodiments of the present disclosure.
[0076] As shown in FIG. 1, the turnover mechanism 1 can include a base weld 11, a swing oil cylinder 12, a turnover arm 13, a first buffering structure 16, and a second buffering structure 17. Figures 4 to 8As shown in the present embodiment, the flipping mechanism 1 may include a sliding arm mechanism 18, the front end of which is fixedly connected to the side of the base welded 11 away from the swing cylinder 12 by bolts.
[0077] like Figure 5 As shown, the sliding arm mechanism 18 may include an outer base assembly 181 and an inner telescopic tube assembly 182. The outer base assembly 181 is bolted to the chassis of the vehicle body. The outer base assembly 181 is hollow, and a removable rear cover 1811 may be provided on the rear end face of the outer base assembly 181. The inner telescopic tube assembly 182 is embedded inside the outer base assembly 181. A flip-up bracket 183 may be provided at the front end of the inner telescopic tube assembly 182. The flip-up bracket 183 is fixed to the top surface of the inner telescopic tube assembly 182 to achieve a fixed connection with the base welding 11.
[0078] It should be noted that the rear end face of the outer base assembly 181 refers to the side of the outer base assembly 181 that is away from the base welding 11.
[0079] Furthermore, the outer base assembly 181 is provided with a telescopic cylinder 184, which includes a front cylinder shaft 1841 and a rear cylinder shaft 1842. The front cylinder shaft 1841 is hinged to the front end of the inner telescopic tube assembly 182, and the rear cylinder shaft 1842 is hinged to the rear end of the outer base assembly 181.
[0080] It should be noted that the front end of the inner telescopic tube assembly 182 refers to the end of the inner telescopic tube assembly 182 that is close to the base weld 11, and the rear end of the outer base assembly 181 refers to the end of the outer base assembly 181 that is far away from the base weld 11. The telescopic cylinder 184 is connected to the inner wall of the sliding arm mechanism 18 through the cylinder front shaft 1841 and the cylinder rear shaft 1842.
[0081] By placing the telescopic cylinder 184 inside the outer base assembly 181, this disclosure reduces the space occupied by the tilting mechanism 1 and simplifies the shape of the tilting mechanism 1, so as to facilitate increasing the telescopic range of the sliding arm mechanism 18 in the future.
[0082] The telescopic oil cylinder 184 can provide power for the telescopic movement of the sliding arm mechanism 18. Specifically, when the rodless cavity of the telescopic oil cylinder 184 is filled with oil, the telescopic oil cylinder 184 pushes the inner telescopic pipe assembly 182 to extend outwardly from the outer base assembly 181 to complete the extension action. When the rod cavity of the telescopic oil cylinder 184 is filled with oil, the telescopic oil cylinder 184 pulls the inner telescopic pipe assembly 182 to retract inwardly from the outer base assembly 181 to complete the retraction action. After the rodless cavity of the telescopic oil cylinder 184 stops being filled with oil, the inner telescopic pipe assembly 182 will immediately stop the telescopic movement. The base weld 11 is fixedly connected with the sliding arm mechanism 18, so that the sliding arm mechanism 18 can drive the base weld 11 to move in the extension direction of the sliding arm mechanism 18 during the telescopic movement, so as to adjust the distance between the base weld 11 and the vehicle body, thereby expanding the range of the bucket holding mechanism 2.
[0083] Further, as shown in Figure 6 the sliding arm mechanism 18 in the embodiment of the present disclosure can further include an upper sliding block 185 and a lower sliding block 186. The upper sliding block 185 is located at the rear end of the inner telescopic pipe assembly 182, and the upper sliding block 185 can be connected with the outer side wall of the inner telescopic pipe assembly 182 by bolts and in contact with the inner side wall of the outer base assembly 181. The lower sliding block 186 is located at the front end of the outer base assembly 181, and the lower sliding block 186 can be connected with the inner side wall of the outer base assembly 181 by bolts and in contact with the outer side wall of the inner telescopic pipe assembly 182.
[0084] It should be understood that the rear end of the inner telescopic pipe assembly 182 refers to the end of the inner telescopic pipe assembly 182 away from the base weld 11, and the front end of the outer base assembly 181 refers to the end of the outer base assembly 181 close to the base weld 11.
[0085] Wherein, the upper sliding block 185 is in surface contact with the inner side wall of the outer base assembly 181, and the lower sliding block 186 is also in surface contact with the outer side wall of the inner telescopic pipe assembly 182, and the lower sliding block 186 and the upper sliding block 185 are located on the same side of the telescopic oil cylinder 184.
[0086] For example, as shown in Figures 6 to 7 the outer base assembly 181 in the present disclosure can be a hollow four-prism, and the bottom surface of the outer base assembly 181 is fixedly connected with the base of the vehicle body, at this time, a set of sliding blocks can be arranged on any one of the four side perimeters of the sliding arm mechanism 18. However, the outer base assembly 181 in the present disclosure can be other hollow shapes other than the four-prism.
[0087] For example, a set of sliding blocks can be arranged on the side surface of the sliding arm mechanism 18 close to the vehicle body base, that is, an upper sliding block 185 is arranged on the outer side wall of the inner telescopic pipe assembly 182 close to the vehicle body base, and a lower sliding block 186 is arranged on the inner side wall of the outer base assembly 181 close to the vehicle body base. When the inner telescopic pipe assembly 182 extends outward from the outer base assembly 181, the upper sliding block 185 approaches the lower sliding block 186 until the upper sliding block 185 abuts against the lower sliding block 186.
[0088] In the embodiment of the present disclosure, the upper sliding block 185 and the lower sliding block 186 are arranged on the same side of the telescopic oil cylinder 184 to limit and guide the telescopic movement of the inner telescopic pipe assembly 182, so that the inner telescopic pipe assembly 182 does not completely separate from the outer base assembly 181 during the extension process, thereby ensuring that the base weld 11 can be driven by the sliding arm mechanism 18 to extend in the extension direction of the sliding arm mechanism 18.
[0089] In addition, by arranging the upper sliding block 185 on the outer side wall of the inner telescopic pipe assembly 182 to abut against the outer base assembly 181, and arranging the lower sliding block 186 on the inner side wall of the outer base assembly 181 to abut against the inner telescopic pipe assembly 182, the friction between the inner telescopic pipe assembly 182 and the outer base assembly 181 during the telescopic movement of the sliding arm mechanism 18 can be reduced, thereby reducing the risk of damage to the inner telescopic pipe assembly 182 and the outer base assembly 181, and prolonging the service life of the inner telescopic pipe assembly 182 and the outer base assembly 181.
[0090] More than two sets of upper sliding blocks 185 and lower sliding blocks 186 can also be arranged in the sliding arm mechanism 18. Taking the outer base assembly 181 as an example, which is a hollow quadrangular prism, one set of upper sliding blocks 185 and lower sliding blocks 186 can be arranged on two, three or four side surfaces of the quadrangular prism to enhance the limiting effect of the inner telescopic pipe assembly 182 and the outer base assembly 181, and further reduce the friction between the inner telescopic pipe assembly 182 and the outer base assembly 181.
[0091] It should be noted that the upper sliding block 185 and the lower sliding block 186 in the embodiment of the present disclosure can be made of wear-resistant materials such as nylon to prolong the service life of the upper sliding block 185 and the lower sliding block 186 and reduce maintenance costs.
[0092] As shown in FIG. 1, Figure 8 In the embodiment of the present disclosure, the sliding arm mechanism 18 can include a bearing set support 187 arranged at the front end of the outer base assembly 181. The bearing set support 187 is embedded in the outer base assembly 181 and in contact with the bottom line of the inner telescopic pipe assembly 182 to provide support for the inner telescopic pipe assembly 182.
[0093] For example, the bearing set support 187 in the embodiment of the present disclosure can be a rolling bearing, so that when the sliding arm mechanism 18 performs the telescopic movement, the bearing set support 187 can provide rolling support for the inner telescopic pipe assembly 182 to reduce the sliding friction between the inner telescopic pipe assembly 182 and the outer base assembly 181, and improve the smoothness and stability of the telescopic movement of the sliding arm mechanism 18.
[0094] It is to be noted that, in the present disclosure, the bearing set support 187 can be arranged at the front end of the outer base assembly 181, and the upper slider 185 can be arranged at the rear end of the outer wall of the inner telescopic pipe assembly 182, and the upper slider 185 and the bearing set support 187 are located on the same side of the telescopic oil cylinder 184. When the inner telescopic pipe assembly 182 extends outward from the outer base assembly 181, the upper slider 185 approaches the bearing set support 187 until abuts against the bearing set support 187. That is, the present disclosure can limit the telescopic distance of the inner telescopic pipe assembly 182 by the cooperation of the bearing set support 187 and the upper slider 185.
[0095] In the embodiment of the present disclosure, the sliding arm mechanism 18 can include a second position sensor 188. The second position sensor 188 is arranged at the front end of the outer base assembly 181 to detect the position of the inner telescopic pipe assembly 182.
[0096] For example, when the second position sensor 188 detects that the inner telescopic pipe assembly 182 is located inside the outer base assembly 181, the telescopic oil cylinder 184 can drive the inner telescopic pipe assembly 182 to extend a certain distance from the inside of the outer base assembly 181 according to the detection result of the second position sensor 188, so as to drive the base weld 11 and the bucket mechanism 2 to move away from the outer base assembly 181. When the second position sensor 188 detects that part of the inner telescopic pipe assembly 182 is located outside the outer base assembly 181, the telescopic oil cylinder 184 can drive the inner telescopic pipe assembly 182 to retract into the outer base assembly 181 according to the detection result of the second position sensor 188, so as to drive the base weld 11 and the bucket mechanism 2 to move close to the outer base assembly 181.
[0097] In addition, when the sliding arm mechanism 18 performs the telescopic movement, the turnover arm 13 and the bucket mechanism 2 can also be synchronously turned over.
[0098] Specifically, as shown in Figure 3 、 Figures 9 to 11 The working process of the turnover mechanism 1 in the embodiment of the present disclosure can be: according to the distance between the bucket mechanism 2 and the garbage can 4, the inner telescopic pipe assembly 182 is controlled to extend a certain distance from the outside of the outer base assembly 181, so that the bucket mechanism 2 tightly holds the garbage can 4. The swing oil cylinder 12 rotates to drive the turnover arm 13 to turn over from the initial position through the first position to the second position, so as to realize the dumping of garbage.
[0099] When the garbage can 4 is held by the bucket holding mechanism 2, the turnover arm 13 is turned from the initial position to the first position, and at the same time, the inner telescopic pipe assembly 182 can be retracted into the inner part of the outer base assembly 181, so that the bucket holding mechanism 2 is close to the vehicle body. In addition, during the process of turning the turnover arm 13 from the initial position to the first position, the rotating shaft 131, which realizes the connection between the second end of the turnover arm 13 and the bucket holding mechanism 2, is also turned, so that the garbage can 4 held by the bucket holding mechanism 2 is kept vertical, and the opening end of the garbage can 4 is upward, thereby avoiding the situation that the garbage in the garbage can 4 leaks out when the turnover arm 13 has not reached the second position.
[0100] When the turnover arm 13 is moved from the first position to the second position, the inner telescopic pipe assembly 182 is retracted into the inner part of the outer base assembly 181, the second end of the turnover arm 13 is moved above the first end, the rotating shaft 131 is turned, the opening end of the garbage can 4 on the bucket holding mechanism 2 is inclined to the vehicle body, so that the opening end of the garbage can 4 is aligned with the vehicle body, and the garbage in the garbage can 4 can be poured onto the vehicle body under the action of gravity.
[0101] When the garbage in the garbage can 4 is poured, the turnover arm 13 is turned downward from the second position to the initial position through the first position, and during the process of turning the turnover arm 13 downward, the rotating shaft 131 is turned to keep the garbage can 4 in the state of the opening end upward, so as to avoid the situation that the residual garbage in the garbage can 4 leaks out. At the same time, the telescopic oil cylinder 184 can drive the inner telescopic pipe assembly 182 to extend outward from the outer base assembly 181, so as to use the bucket holding mechanism 2 to put the garbage can 4 back to the original position. When the garbage can 4 is released, the clamping on the bucket holding mechanism 2 is in the maximum open state, and after the garbage can 4 is released, the slide arm mechanism 18 is retracted, so that the base weld 11 and the bucket holding mechanism 2 move to the side edge of the vehicle body.
[0102] It should be noted that the initial position of the turnover arm 13 can correspond to Figure 3 the position of the turnover arm 13. The turning angle of the turnover arm 13 from the initial position to the first position can be 90°, and the specific turning angle can be referred to Figure 10 the position of the turnover arm 13. The turning angle of the turnover arm 13 from the initial position to the second position can be 180°, and the specific turning angle can be referred to Figure 11 the position of the turnover arm 13. However, it is not limited to this, and the turning angle of the turnover arm 13 from the initial position to the first position and the second position can be set according to the actual situation.
[0103] In the embodiments of the present disclosure, the turnover mechanism 1 can further include a support structure 171 and a drag chain 17. The support structure 171 is fixed to the base weld 11 on the side away from the swing oil cylinder 12 and is arranged adjacent to the sliding arm mechanism 18. The drag chain 17 extends along the length direction of the sliding arm mechanism 18. One end of the drag chain 17 is connected to the support structure 171, and the other end is fixedly connected to the base of the vehicle body. When the sliding arm mechanism 18 performs the extension and retraction movement, the drag chain 17 can perform the extension and retraction movement together in the extension direction of the sliding arm mechanism 18, so as to realize the traction and protection of the hydraulic oil pipes and electrical harnesses in the turnover mechanism 1.
[0104] It should be noted that the drag chain 17 in the present disclosure can be arranged on the top surface of the sliding arm mechanism 18 (i.e., the side away from the base of the vehicle body), but is not limited thereto. The drag chain 17 can also be arranged on the side surface of the sliding arm mechanism 18. At this time, the drag chain 17 is fixed side by side with the sliding arm mechanism 18, so as to reduce the gap between the top surface of the sliding arm mechanism 18 and the vehicle body, and further increase the volume of the filler hopper arranged on the top surface of the sliding arm mechanism 18, so as to increase the capacity of the filler hopper for loading garbage.
[0105] The embodiments of the present disclosure further provide a sanitation vehicle, which includes a vehicle body, a bucket holding mechanism 2, and any one of the turnover mechanisms 1 as described above, and the turnover mechanism 1 is connected to the vehicle body.
[0106] In the embodiments of the present disclosure, the outer base assembly 181 can be fixed to the auxiliary frame or the upper surface of the chassis beam in the vehicle body. The base weld 11 and the bucket holding mechanism 2 in the turnover mechanism 1 can be arranged on one side edge of the vehicle body, for example, the base weld 11 and the bucket holding mechanism 2 are arranged on the right side edge of the vehicle body. When the sliding arm mechanism 18 performs the extension and retraction movement, the base weld 11 and the bucket holding mechanism 2 can extend from the right side edge of the vehicle body to the position of the garbage can 4, so as to facilitate the bucket holding mechanism 2 to hold the garbage can 4.
[0107] The bucket holding mechanism 2 on the sanitation vehicle can adapt to garbage cans 4 of various specifications, such as 120L, 240L, and the like, so as to improve the practicability of the bucket holding mechanism 2.
[0108] Further, the sanitation vehicle can further include a buffer 3. The buffer 3 is located on the side of the base weld 11 away from the swing oil cylinder 12 and is fixedly connected to the top of the base weld 11. When the base weld 11 moves towards the vehicle body, the buffer 3 abuts between the base weld 11 and the vehicle body, so as to reduce the impact between the base weld 11 and the vehicle body, thereby reducing the risk of damage to the base weld 11 and the vehicle body, and reducing the maintenance cost of the base weld 11 and the vehicle body.
[0109] In the embodiments of the present disclosure, the operation of the turnover mechanism 1 and the bucket holding mechanism 2 can be fully automated, which can improve the efficiency of garbage recycling and reduce the working intensity of the staff. With the development of unmanned technology, the turnover mechanism 1 in the present disclosure can also be applied to the unmanned sanitation vehicle.
