Description

Technical Field

[0001] The utility model belongs to the technical field of garbage trucks, and particularly relates to a bucket lifting device and a garbage truck. Background Art

[0002] The bucket lifting mechanism is applied to a garbage truck and is an automatic mechanism for vertically lifting a garbage bin to a high position and then turning it upward to dump the garbage in the garbage bin into the carriage. The prior art CN202323193849.9 discloses a bucket lifting mechanism. The bucket lifting mechanism adopts a link type design. The top cover is driven by an oil cylinder at the top of the garbage bin. The top cover pulls the link, and the link drives the bucket turning frame to run in a fixed track. When the bucket turning frame runs to the highest point of the track, the lower pulley of the bucket turning frame disengages from the track, and only the upper pulley is in the track. By continuously driving the top cover, the bucket turning frame can rotate around the central axis of the upper pulley, so as to realize turning and dumping garbage. Although this bucket lifting mechanism can ensure the lifting and turning of the garbage bin, when lowering the garbage bin, it can only rely on the gravity of the garbage bin itself to turn downward, and there is a situation where the upper pulley of the bucket turning frame moves in the track while the lower pulley cannot return to the track, which easily causes damage to the bucket lifting mechanism. Content of the Utility Model

[0042] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0043] The following describes the bucket lifting device and the garbage truck of the present invention with reference to the accompanying drawings.

[0044] As Figure 1 shown, the present invention provides a bucket lifting device, wherein the bucket lifting device includes:

[0045] A bucket lifting frame mechanism, including a track frame 1 and a bucket hanging frame assembly 2. The upper end of the track frame 1 is pivotally hinged to the garbage bin 5. The bucket hanging frame assembly 2 is used to carry the dustbin 7, and the moving pair 21 of the bucket hanging frame assembly 2 is movably arranged on the track frame 1;

[0046] A top cover flipping mechanism 3, which is drivingly connected to the bucket hanging frame assembly 2. The top cover flipping mechanism 3 is used to drive the bucket hanging frame assembly 2 and the dustbin to rise to abut against the upper end of the track frame 1 when the top cover 51 of the garbage bin 5 is opened, so as to cause the track frame 1 to flip upward.

[0047] When using the above bucket lifting device to perform garbage dumping work, the dustbin 7 is fixed on the bucket hanging frame assembly 2. The top cover flipping mechanism 3 drives the bucket hanging frame assembly 2 to rise along the track frame 1. Since the upper end of the track frame 1 is hinged to the garbage bin 5, when the bucket hanging frame assembly 2 and / or the dustbin 7 abut against the upper end of the track frame 1, the top cover flipping mechanism 3 can drive the track frame 1 to flip upward through the bucket hanging frame assembly 2, so that the garbage in the dustbin 7 enters the garbage bin 5 along the feeding port at the top of the garbage bin 5; compared with the existing scheme, the bucket lifting device provided by the present invention can make the bucket hanging frame assembly 2 and the track frame 1 flip synchronously, and the moving pair 21 on the bucket hanging frame assembly 2 does not need to be disengaged from the track frame 1, which can avoid the situation that the moving pair 21 cannot return to the track frame 1, improve the reliability of the bucket lifting device work, and reduce the noise.

[0048] To achieve the upward flipping of the track rack 1, the bucket hanging rack assembly 2 and / or the trash can 7 may be in contact with the upper end of the track rack 1. Preferably, referring to Figure 2 and Figure 3 , a bucket pressing plate 4 is provided at the upper end of the track rack 1. The bucket pressing plate 4 is used to contact the edge of the mouth of the trash can 7, so as to avoid problems such as deformation and noise caused by the collision between the bucket hanging rack assembly 2 and the track rack 1.

[0049] In addition, in the prior art solutions, to meet the flipping of the bucket hanging rack, the moving pair of the bucket hanging rack adopts the design of upper and lower pulleys, and a guiding groove is provided on the arc section of the slide rail. The lower pulley disengages from the slide rail along the guiding groove. The dimensions of the slide rail and the pulleys determine the distance between the upper and lower pulleys. In order to ensure the width and height dimensions of the whole vehicle, the distance between the upper and lower pulleys is generally set to be small, resulting in a large flipping moment borne by the upper and lower pulleys during the process of lifting the trash can 7, which is likely to cause serious wear to the slide rail and itself, increasing the after-sales maintenance cost. Different from this, in the bucket lifting device provided by the present utility model, the track rack 1 will flip synchronously with the bucket hanging rack assembly 2, and the moving pair 21 does not need to disengage from the lifting guide rail 121, so the moving pair 21 is preferably a slider. Compared with the solution using pulleys, on the one hand, the cost can be reduced; on the other hand, the contact area between the slider and the lifting guide rail 121 is larger, thereby reducing the local load on the lifting guide rail 121 and the moving pair 21 and reducing wear.

[0050] Furthermore, the bucket hanging rack assembly 2 includes a moving pair 21, a connecting plate 22 and a supporting rod 23. The moving pair 21 is movably arranged in the lifting guide rail 121. The inner side of the moving pair 21 is connected to the connecting plate 22. The connecting plate 22 is connected to the pull rod 32 of the top cover flipping mechanism 3. The supporting rod 23 extends upward from the connecting plate 22; when performing the dumping operation, the operator first aligns the bucket hanging rack assembly 2 with the trash can 7. In the initial state, the bucket hanging rack assembly 2 is located at the lowest point of the track. The mouth of the trash can 7 is higher than the bucket hanging rack assembly 2, and a groove 71 with a downward opening is provided at the edge of the mouth. The top cover flipping mechanism 3 drives the bucket rack assembly to move along the lifting guide rail 121 of the track rack 1. During the process of driving the bucket rack assembly to rise, the supporting rod 23 extends into the groove 71 to drive the trash can 7 to rise synchronously. When the trash can 7 rises vertically to contact the bucket pressing plate 4, the supporting rod 23 and the bucket pressing plate 4 cooperate to clamp the trash can 7 to prevent the trash can 7 from falling when the track rack 1 is in the flipping state; the process of lifting and fixing the trash can 7 utilizes the existing structure of the trash can 7 without the need to improve the trash can 7, and has strong versatility.

[0051] Such as Figure 3As shown, in the embodiment of the present utility model, the track frame 1 includes a track main body 12 and a connecting portion 11. The track main body 12 allows the hanging bucket frame assembly 2 to move up and down. The connecting portion 11 is provided at the upper end of the track frame 1, and the connecting portion 11 includes a vertical section 111 connected to the track frame 1 and a horizontal section 112 extending and bending from the upper end of the vertical section 111 towards the trash bin 5. One end of the horizontal section 112 away from the vertical section 111 is hinged to the trash bin 5, and the pressing bucket plate 4 is connected to the vertical section 111. Compared with the solution of directly hinging the track main body 12 to the trash bin 5, through the bent connecting portion 11, the pressure angle when the top cover flipping mechanism 3 drives the track frame 1 is reduced, and the driving force of the top cover flipping mechanism 3 can be set smaller, thereby reducing the load of the track frame 1 and the hanging bucket frame assembly 2. Specifically, the track main body 12 includes two parallel tracks and a cross beam connected between the two tracks, and the number of the connecting portions 11 is also set to two, and the two connecting portions 11 are respectively connected to the two tracks correspondingly.

[0052] Further, referring to Figure 3 and Figure 4 , in the embodiment of the present utility model, the track main body 12 is formed with a lifting guide rail 121 for the hanging bucket frame assembly 2 to move up and down, and a notch 41 is formed on the pressing bucket plate 4. The upper end of the lifting guide rail 121 is arranged vertically along the vertical section 111 through the notch 41. The moving pair 21 of the hanging bucket frame assembly 2 can pass through the notch 41 along the lifting guide rail 121, and the trash can 7 is stopped and limited at the pressing bucket plate 4. By opening the notch 41 on the pressing bucket plate 4, it can be ensured that the hanging bucket frame assembly 2 runs up and down without interference and collision, and at the same time, the guiding overlapping area between the moving pair 21 and the track can be further increased, and the interaction force area can be increased.

[0053] As Figure 5 and Figure 6 shown, in the embodiment of the present utility model, the bucket lifting device further includes a frame fixing component 6, and the frame fixing component 6 can limit the track frame 1 that is flipped downwards in place to prevent the track frame 1 from shaking during the operation of the garbage truck. Specifically, referring to Figure 6, in an embodiment of the present utility model, the frame fixing assembly 6 includes a downward movement limiting member 61 and a downward movement limiting channel 62. The downward movement limiting member 61 is provided on the hanging bucket frame assembly 2, and the channel space of the downward movement limiting channel 62 is arranged along the lifting direction of the hanging bucket frame assembly 2. When the hanging bucket frame assembly 2 descends to the lowest position, the downward movement limiting member 61 enters the channel space. When the hanging bucket frame assembly 2 ascends to a certain height, the downward movement limiting member 61 disengages from the channel space; in another embodiment of the present utility model, the frame fixing assembly 6 includes a downward pressing limiting member 63 provided on the top cover 51. The downward pressing limiting member 63 is provided with a pressing rod, and the pressing rod passes through the top cover 51. When the top cover 51 is closed, the pressing rod presses on the track frame 1 to prevent the track frame 1 from flipping before the top cover 51 is opened. It should be noted that the above two embodiments can be set simultaneously or one of them can be selected and set alone. Of course, the present utility model is not limited thereto. The frame fixing assembly 6 can also be set as structures such as a buckle or a locking pin, and it is also possible for the operator to manually lock the track frame 1.

[0054] As Figure 2 shown, in an embodiment of the present utility model, a buffer block 13 is further provided on the side of the track frame 1 facing the trash bin 5. The setting of the buffer block 13 can prevent the track frame 1 from directly colliding with the trash bin 5 and damaging the equipment, and at the same time can also reduce noise.

[0055] As Figure 2 shown, in an embodiment of the present utility model, the top cover flipping mechanism 3 includes a telescopic driving member 31 and a pull rod 32. The telescopic driving member 31 is provided on the trash bin 5 and is drivingly connected to the top cover 51. The two ends of the pull rod 32 are respectively hinged to the hanging bucket frame assembly 2 and the top cover 51 in a one-to-one correspondence. The top cover flipping mechanism 3, the hanging bucket frame assembly 2, and the top cover 51 of the trash bin 5 form a mechanism that moves synchronously, which can reduce the number of driving members.

[0056] Specifically, referring to Figure 7 , a top cover 51 is provided on the top plate of the trash bin 5. First hinge seats 52 and second hinge seats 53 are arranged at intervals on the side of the top cover 51. The first hinge seat 52 is used for hinging the top cover 51, and the second hinge seat 53 is used for hinging the telescopic driving member 31 and the track frame 1. Raised connecting plate portions are provided on both sides of the top cover 51. The connecting plate portions include a first connecting section 511, an intermediate section 512, and a second connecting section 513 that are sequentially connected along the width direction of the trash bin 5. A first hinge point and a second hinge point are provided on the first connecting section 511. The connection line from the first hinge point to the second hinge point extends obliquely upward along the width direction of the trash bin 5. The first hinge point corresponds to the first hinge seat 52, and the second hinge point corresponds to the telescopic driving member 31; the second connecting section 513 extends downward and bends from the intermediate section 512 and is connected to the pull rod 32.

[0057] In the embodiment of the present utility model, the pull rod 32 is inclined upward from bottom to top towards the garbage bin 5 when the top cover 51 is in the closed state. When the hanging bucket frame assembly 2 moves upward along the lifting guide rail 121, the center line of the pull rod 32 always deviates towards the side of the garbage bin 5, and the horizontal component force of the top cover flipping mechanism 3 on the hanging bucket frame assembly 2 points to the side where the garbage bin 5 is provided, thereby pressing the track frame 1 against the side wall of the garbage bin 5 to prevent the track frame 1 from flipping before the trash can 7 abuts against the pressing bucket plate 4.
