[0002] In the development process of the construction industry, the treatment and reuse of construction waste has always been an issue that construction units have been committed to improving. In the process of treating construction waste, the garbage truck loaded with garbage needs to be lifted to a certain height and dumped into a storage bin or garbage treatment equipment for processing.

[0003] To achieve the automated lifting and dumping function of garbage carts, our company's previous design, patent number CN220010879U, uses a chain drive mechanism to lift the lifting platform upward along the vertical trough frame and complete the dumping action along the arc trough frame. The vertical trough frame and the arc trough frame in this patent are a spliced ​​structure connected by a trough, that is, the lifting and dumping of the lifting platform use the same track. In actual application, the following problems are found:

[0004] (1) Most construction waste is heavy garbage such as concrete, tiles, bricks, etc., which makes the garbage cart full of garbage heavier. During the lifting process of the garbage cart, the rigidity of the single track is insufficient and it is easy to deform, which makes the lifting platform not smooth and has a short service life.

[0005] (2) When designing a single-track arc trough frame, the garbage cart fully loaded with garbage is heavy and can easily bend or break the single track. Therefore, the bending angle of the arc trough frame is limited, resulting in the garbage cart's dumping angle being too small and incomplete garbage dumping.

[0006] Therefore, in order to solve the above problems, there is an urgent need for an improved lifting and dumping device for processing construction waste. Utility Model Content

[0030] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0031] Example 1

[0032] like Figures 1-4 The illustrated embodiment of a dual-track lifting and dumping device for construction waste disposal according to the present invention includes a base plate 1, a lifting mechanism 2 mounted on the base plate 1, a dual-track lifting frame assembly 3 symmetrically fixed at both ends of the base plate 1, and a lifting platform 4 connected to the output end of the lifting mechanism 2. The dual-track lifting frame assembly 3 includes two vertical guide rails 31 symmetrically arranged at both ends of the base plate 1 and two dumping guide rails 32 symmetrically fixed at both ends of the base plate 1. The dumping guide rail 32 and the vertical guide rail 31 are arranged side by side at the same end of the base plate 1, and the upper end of the dumping guide rail 32 is bent away from the vertical guide rail 31. The lifting platform 4 includes an L-shaped support frame 41, dumping wheels 43 symmetrically mounted on both sides of the L-shaped support frame 41 via upper ears 42, a guide support assembly 44 mounted at the rear end of the L-shaped support frame 41, and at least two guide wheels 45 symmetrically mounted on both sides of the guide support assembly 44. The dumping wheels 43 slide in conjunction with the corresponding dumping guide rails 32, and the guide wheels 45 slide in conjunction with the corresponding vertical guide rails 31.

[0033] Specifically, the vertical guide rail 31 in this embodiment includes a vertical column 311 fixedly mounted on the base plate 1 and a first guide groove 312 arranged on the inner side of the vertical column 311. The tipping guide rail 32 includes a tipping column 321 fixedly mounted on the base plate 1 and a second guide groove 322 arranged on the inner side of the tipping column 321. When in use, the guide wheel 45 slides in the corresponding first guide groove 312, and the tipping wheel 43 slides in the corresponding second guide groove 322.

[0034] The present embodiment is designed with a double-track lifting frame assembly based on the existing single track, wherein vertical guide rails 31 are arranged side by side on the sides of the dumping guide rails 32, and a dumping wheel 43 is arranged on the upper part of the lifting platform 4 through the upper ear frame 42, and a guide wheel 45 is arranged on the middle and / or lower part of the lifting platform 4 through the guide support assembly 44, and the dumping wheel 43 is cooperated with the corresponding dumping guide rail 32 to slide, and the guide wheel 45 is cooperated with the corresponding vertical guide rail 31 to slide. The utility model arranges the guide wheel 45 and the dumping wheel 43 on two tracks respectively. On the one hand, the two tracks are arranged side by side to increase the bearing capacity. On the other hand, when dumping, the dumping wheel 43 and the guide wheel 45 are located on different tracks, so that the height of the guide wheel 45 in the vertical direction can be higher than the height of the dumping wheel 43, so that the dumping angle is not limited, thereby solving the problems of small load-bearing capacity, variability and incomplete garbage dumping of the guide rails in the prior art.

[0035] like Figure 1 As shown, the vertical columns 311 and the dumping columns 321 in this embodiment are arranged side by side with a gap on the base plate 1. During the process of lifting and dumping the garbage cart 6, the guide wheels 45 on both sides of the guide support assembly 44 are placed in the corresponding vertical columns 311, and the dumping wheels 43 set on both sides of the upper part of the L-shaped load-bearing frame 41 are placed in the corresponding dumping columns 321. The weight of the garbage cart 6 fully loaded with construction waste is distributed on the vertical guide rails 31 and the dumping guide rails 32, thereby increasing the load-bearing capacity of the guide rails. As a preferred embodiment, four guide wheels 45 are provided in this embodiment, and are symmetrically arranged on both sides of the guide frame. Figure 1 and Figure 4 The two guide grooves 322 of the upper part 322 are respectively arranged in the two second guide grooves 322 and 323 of the lower part 323. When the lifting platform 4 is lifted up, the upper end of the lifting platform 4 is lifted up, and the second guide groove 322 is also bent to the same side. The second guide groove 322 guides the tipping wheel 43 to move in the bending direction. At this time, the guide wheels 45 on the guide frame still slide in the vertically arranged first guide groove 312, and the guide frame and the supporting vertical frame are rotated and installed. The supporting vertical frame drives the garbage cart 6 on the pallet to dump the construction garbage into the bending direction cavity, thereby realizing the automatic loading of the construction garbage in the garbage cart 6 into the garbage processing equipment or storage bin, without the need for manual handling, which greatly saves manpower and financial investment.

[0036] In order to meet the dumping requirements of the garbage cart 6, the construction waste in the garbage cart 6 is completely dumped into the garbage processing equipment or storage bin, such as Figure 2 As shown, the vertical height of the vertical column 311 in this embodiment is greater than the vertical height of the dumping column 321. The vertical height of the vertical column 311 is greater than the vertical height of the dumping column 321, so that the position of the guide wheel 45 on the guide rail can be higher than the position of the tilting wheel, so that the L-shaped carrier frame 41 can flip over a larger angle, driving the garbage cart 6 to flip over a larger angle, so that the construction waste in the garbage cart 6 can be completely and residue-free dumped into the garbage treatment equipment or storage bin.

[0037] It should be understood that the L-shaped support frame 41 in the first embodiment is also equipped with a limiting mechanism 5 to prevent the garbage cart 6 from falling during the dumping or lifting process. As a preferred embodiment, the L-shaped support frame 41 includes a vertical frame, a horizontal frame fixedly connected to the vertical frame, and a support plate mounted on the horizontal frame. The limiting mechanism 5 includes an inverted L-shaped limiting plate 51 provided on the L-shaped support frame 41 and a hanging bracket 52 provided on the bottom of the garbage cart 6. Specifically, the inverted L-shaped limiting plate 51 is fixedly mounted on the support plate. When in use, the garbage cart 6 is pushed onto the support plate on the horizontal frame, so that the hanging bracket 52 on the garbage cart 6 is sleeved on the inverted L-shaped limiting plate 51, effectively preventing the garbage cart 6 from separating from the support plate and falling from the dumping side during dumping.

[0038] like Figure 2 As shown, the lifting mechanism 2 in the present invention can be driven by a cylinder or an electric push rod. As an implementation method, the lifting mechanism 2 in this embodiment 1 includes a two-stage lifting assembly 22 and a first-stage lifting cylinder 21 vertically installed on the base plate 1. The fixed end of the first-stage lifting cylinder 21 is installed on an external mounting platform for fixing the lifting mechanism 2, and the output end of the first-stage lifting cylinder 21 rotates with the base plate 1. The setting of the first-stage lifting cylinder 21 can adjust the distance between the base plate 1 and the ground, which facilitates the movement of the external mounting platform for fixing the lifting mechanism 2. When the mounting platform needs to be moved, the first-stage lifting cylinder 21 is in a retracted state, so that the base plate 1 is set away from the ground. When the garbage cart 6 needs to be pushed onto the lifting platform 4, the first-stage lifting cylinder 21 is in an extended state, and the base plate 1 falls to the ground to solve the problem of inconvenient movement of the mounting platform.

[0039] It should be understood that the first-stage lifting cylinder 21 in this embodiment 1 can also be replaced by an electric push rod. As long as the component has a telescopic function, it can be applied to this embodiment 1. On the basis of this application, the replacement made by technical personnel in this field without creative work should be within the scope of protection of this utility model.

[0040] like Figure 1 and Figure 2As shown, the secondary lifting assembly 22 in the first embodiment includes a secondary lifting cylinder 221 whose fixed end is fixedly mounted on the base plate 1, a lifting rod 222 fixedly mounted to the output end of the secondary lifting cylinder 221, lifting sprockets 223 respectively mounted on both ends of the lifting rod 222, a lifting beam 224 fixed to two tilting columns 321, and a lifting chain connected to the lifting sprockets 223. One end of the lifting chain is mounted on the L-shaped support frame 41 of the lifting platform 4, and the other end is mounted on the lifting beam 224. Specifically, one end of the lifting chain is mounted on the lifting platform 4, and the other end passes around the lifting sprocket 223 and is fixed to the lifting beam 224. In this embodiment, the lifting beam 224 is set in the middle of the vertical column 311. Of course, the lifting beam 224 can also be installed at other positions on the vertical column 311. As long as the length of the lifting chain and the position of the lifting beam 224 meet the lifting requirements, the position of the lifting beam 224 is not absolutely limited here. It is only necessary to start the secondary lifting cylinder 221 to drive the dumping wheel 43 to roll upward in the second guide groove 322, and at the same time drive the guide wheel 45 to roll upward in the first guide groove 312 to achieve the lifting or dumping of the garbage cart 6.

[0041] The flipping angle of the lifting platform 4 in this embodiment on the double-track lifting frame assembly 3 can be adjusted according to the requirements of use by adjusting the bending angle of the upper end of the tipping column 321 or the height of the tipping column 321 and the vertical column 311, and can be adapted to larger flipping angle requirements. At the same time, the guide wheel 45 and the tipping wheel 43 slide on separate tracks, which greatly improves the load-bearing capacity of the double-track lifting frame assembly 3, increases the service life of the lifting device and the flipping and dumping accuracy.

[0042] Example 2

[0043] Compared to the first embodiment, the second embodiment differs in that the vertical columns 311 and the tilting columns 321 are arranged side by side without gaps on the base plate 1; the vertical columns 311 and the tilting columns 321 are fixed together by welding or screws. During the lifting and tilting process of the garbage cart 6, the vertical columns 311 and the tilting columns 321 are arranged side by side without gaps in the untilted portions, further increasing their load-bearing capacity and facilitating the sliding installation of the vertical columns 311 and the tilting columns 321 relative to the mounting platform.

[0044] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
