Description

Technical Field

[0001] This utility model relates to the technical field of garbage compression equipment, specifically a walking mechanism for a vertical garbage compressor. Background Technology

[0002] With the increasing demand for the sorting, processing, compression, and transportation of household waste, more and more medium- and large-sized waste transfer stations are choosing the high-input, horizontal-output vertical waste compression process, which is more conducive to waste sorting, more suitable for large-scale compression and transportation, and has greater environmental advantages. This aims to improve the level of household waste transportation in the region, enhance public health, improve the investment environment, and promote the coordinated development of regional environmental protection and economy.

[0003] Our research into numerous publicly available patents and actual products in the industry revealed that compactors in waste compression stations commonly use two installation methods: ground rail and suspended rail. Both of these methods require modifications to the compactor's structure before they can be installed using either the suspended or ground rail. This results in two different compactor forms for suspended and ground rail installations, meaning the same compactor cannot be used for both. However, in real-world market applications, compactors, as a core component of waste transfer stations, should not have multiple forms, as this would increase production costs and impose higher assembly requirements. Utility Model Content

[0004] The purpose of this invention is to provide a walking mechanism for a vertical garbage compactor to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a walking mechanism for a vertical garbage compactor, comprising a walking mechanism and a compactor, wherein the compactor is movably disposed inside the walking mechanism, the walking mechanism is movably disposed inside the steel structure frame of the garbage compactor, a first walking component is provided at the bottom of the outer wall of the compactor, an X-axis track component matching the walking mechanism is provided on one side of the top of the inner wall of the steel structure frame, and a plurality of first Y-axis track components matching the first walking component are provided on the other side of the top of the inner wall of the steel structure frame, the walking mechanism comprising a support frame and a second walking component, the second walking component being disposed on the outer wall of the support frame, and a second Y-axis track component matching the first walking component being provided on the inner wall of the support frame.

[0006] Furthermore, the first Y-axis track assembly and the second Y-axis track assembly are located on the same horizontal line.

[0007] Furthermore, the second traveling assembly includes a geared motor, a drive gear, and two sets of first and second rollers. The output shaft of the geared motor is connected to the drive gear via a coupling. The drive gear is rotatably mounted on the outer wall of the support frame. The X-axis track assembly includes a rack and two sets of first and second guide rails. The drive gear and rack mesh with each other. The second guide rail is located on the top of the first guide rail, and the rack is located on the side wall of the first guide rail. The first and second rollers are rotatably mounted on the outer wall of the support frame. The first rollers are in rolling contact with the first guide rail, and the second rollers are in rolling contact with the second guide rail.

[0008] Furthermore, in the ground rail installation scheme, the second Y-axis rail assembly is located above the geared motor.

[0009] Furthermore, in the hanging rail installation scheme, the second Y-axis rail assembly is located below the geared motor.

[0010] Furthermore, the rotation axis of the first roller is perpendicular to the rotation axis of the second roller.

[0011] Furthermore, the first walking component includes a power platform and two sets of walking wheels. The two sets of walking wheels are respectively located on both sides of the bottom of the power platform, and the drive motor inside the power platform is connected to the walking wheels for transmission.

[0012] Furthermore, the horizontal distance between the first Y-axis track assembly and the second Y-axis track assembly is less than the center distance between two adjacent walking wheels in each group of walking wheels.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model, by setting up a walking mechanism, a first walking component, an X-axis track component, a first Y-axis track component, a second walking component, and a second Y-axis track component, provides two installation configurations for the walking mechanism. The first configuration is a forward installation, where the walking mechanism is located at the lower half of the compactor, supporting the compactor and enabling movement behind the workstation, thus achieving a ground-rail solution. The second configuration is an inverted installation, where the walking mechanism is located at the upper half of the compactor, suspending the compactor and enabling movement behind the workstation, thus achieving a suspended track solution. Without altering the mechanical structure of the walking mechanism, both configurations can be achieved through the rollers of the walking mechanism and... Different installation positions of the drive unit enable the walking mechanism to meet the application requirements of different solutions. Based on the principle of modular design, the compactor shape is fixed, so that the compactor is no longer limited by the direction of the ground rail or hanging rail solution. The customer's ground rail or hanging rail requirements can be met by changing the installation position of the walking mechanism. In this way, the compactor can be used as a fixed product for different solution requirements, making it more compatible, applicable and flexible. Without changing the mechanical structure of the walking mechanism, the above two forms can meet the application requirements of the walking mechanism in different solutions by different installation positions of the rollers and drive components of the walking mechanism.

[0015] 2. In this utility model, the walking mechanism drive mechanism is not used for load-bearing, but only for driving movement. The load-bearing of the mechanism relies on the first and second rollers of the walking mechanism, both of which are driven wheels. The driving of the walking mechanism, i.e., the X-axis movement, adopts a gear and rack meshing drive scheme to avoid positioning errors caused by the sliding friction of the brake rollers. An encoder is used to record the precise position of the walking mechanism, and the encoder data is calibrated by proximity switches at each parking spot to ensure accurate positioning of the walking mechanism. The drive gear transmits the torque of the drive reduction motor through a universal joint coupling to reduce the installation difficulty between the reduction motor and the drive gear and improve product reliability. The rack is fixed in the X-axis track beam of the steel structure, and the rotation of the drive gear drives the walking mechanism to move in the X-axis direction. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-11This utility model provides a technical solution: a walking mechanism for a vertical garbage compactor, including a walking mechanism 2 and a compactor 4. The compactor 4 is movably disposed inside the walking mechanism 2, and the walking mechanism 2 is movably disposed inside the steel structure frame 1 of the garbage compactor. A first walking component 9 is provided at the bottom of the outer wall of the compactor 4. An X-axis track component 7 matching the walking mechanism 2 is provided on one side of the top of the inner wall of the steel structure frame 1. The X-axis track component 7 is located behind the unloading berth. A plurality of first Y-axis track components 6 matching the first walking component 9 are provided on the other side of the top of the inner wall of the steel structure frame 1. The first Y-axis track components 6 are located above the unloading berth. The first Y-axis track components 6 and the X-axis track components 7 are connected in terms of walking route or space. The walking mechanism 2 includes a support frame 5 and a second walking component 3. The second walking component 3 is disposed on the outer wall of the support frame 5. A second Y-axis track component 8 matching the first walking component 9 is provided on the inner wall of the support frame 5.

[0031] In one embodiment, the first Y-axis track assembly 6 and the second Y-axis track assembly 8 are located on the same horizontal line to ensure the smooth movement of the first traveling component 9 of the compactor 4 from the first Y-axis track assembly 6 and the second Y-axis track assembly 8.

[0032] In one embodiment, the second traveling assembly 3 includes a reduction motor 301, a drive gear 302, and two sets of first rollers 303 and second rollers 304. The output shaft of the reduction motor 301 is connected to the drive gear 302 via a coupling. The drive gear 302 is rotatably mounted on the outer wall of the support frame 5. The X-axis track assembly 7 includes a rack 701 and two sets of first guide rails 702 and second guide rails 703. The drive gear 302 and the rack 701 mesh with each other. The second guide rail 703 is located on the top of the first guide rail 702, and the rack 701 is located on the side wall of the first guide rail 702. The first rollers 303 and the second rollers 304 are evenly distributed. The first roller 303 and the second roller 304 are mounted on the outer wall of the support frame 5 and roll in contact with the first guide rail 702. When the second walking component 3 is working, the reduction motor 301 drives the drive gear 302 to rotate through the coupling. The drive gear 302 meshes with the rack 701, so that the drive gear 302 can roll along the rack 701. The first roller 303 rolls along the first guide rail 702, and the second roller 304 rolls along the second guide rail 703. This can effectively ensure the stability of the movement of the second walking component 3, and thus ensure the stability of the movement of the walking mechanism 2.

[0033] In one embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7As shown, the second Y-axis track assembly 8 is located below the reduction motor 301. At this time, the walking mechanism 2 is located in the upper part of the compactor 4, suspending the compactor 4 to move on the rear side of the workstation, thus realizing the hanging rail scheme and realizing the hanging rail installation of the compactor 4.

[0034] In one embodiment, such as Figure 5 , Figure 8 As shown, the second Y-axis track assembly 8 is located above the reduction motor 301. At this time, the walking mechanism 2 is located in the lower half of the compactor 4, supporting the compactor 4 to move behind the workstation, thus realizing the ground rail solution and realizing the ground rail installation of the compactor 4.

[0035] In one embodiment, the rotation axis of the first roller 303 is perpendicular to the rotation axis of the second roller 304, so that the first roller 303 and the second roller 304 perform rolling guidance processing on the walking mechanism 2 in two different directions, which can effectively ensure the stability of the movement of the walking mechanism 2.

[0036] In one embodiment, the first traveling component 9 includes a power platform 901 and two sets of traveling wheels 902. The two sets of traveling wheels 902 are respectively located on both sides of the bottom of the power platform 901. A drive motor inside the power platform 901 is connected to the traveling wheels 902. The drive motor drives the traveling wheels 902 to rotate, thereby driving the compactor 4 to travel in the Y-axis direction. The horizontal distance between the first Y-axis track assembly 6 and the second Y-axis track assembly 8 is less than the center distance between two adjacent traveling wheels 902 in each set. Two sets of traveling wheels 902 are provided, and the center distance between two adjacent traveling wheels 902 in each set is greater than the mating gap between the first Y-axis track assembly 6 and the second Y-axis track assembly 8. To ensure that at least three rollers are located on top of the first Y-axis track assembly 6 and the second Y-axis track assembly 8 when crossing the docking gap, the compactor 4 can smoothly pass through the docking gap and travel from the walking area to the compression area for compression operations. Conversely, the compactor 4 can also smoothly travel from the compression area to the walking area, return to the walking mechanism track beam, and travel with the walking mechanism 2 to other berths. The power platform 901 is also equipped with a mechanism that interlocks with the walking mechanism 2. When traveling in the X direction, the support frame 5 of the power platform 901 and the walking mechanism 2 is locked. When traveling in the Y direction, the support frame 5 of the power platform 901 and the walking mechanism 2 is unlocked, ensuring that there is no relative displacement between the compactor 4 and the walking mechanism 2 when the walking mechanism travels in the X direction, making the equipment operate more safely.

[0037] The working principle of this utility model:

[0038] Refer to the instruction manual appendix Figures 1-11This utility model is constructed by setting up a walking mechanism 2, a first walking component 9, an X-axis track component 7, a first Y-axis track component 6, a second walking component 3, and a second Y-axis track component 8.

[0039] The ground-rail scheme refers to a system where the X-axis traveling track is located at the bottom of the compactor, and its installation height is slightly higher than the unloading area elevation, such as... Figure 5 , Figure 8 As shown; the suspended rail scheme refers to the X-axis traveling rail being located at the top of the compactor, with its installation height significantly higher than the unloading area elevation, such as... Figure 4 , Figure 6 As shown;

[0040] Based on the modular design principle, this utility model fixes the form of the compactor 4, so that the compactor 4 is no longer restricted by the direction of the ground rail scheme or the hanging rail scheme. The customer's ground rail or hanging rail needs can be met by changing the installation position of the walking mechanism 2. In this way, the compactor 4 can be used as a fixed product for different scheme needs, making it more compatible, applicable and flexible.

[0041] This traveling mechanism 2 has two installation configurations. The first configuration is a forward installation, in which the traveling mechanism 2 is located at the lower half of the compactor 4, supporting the compactor 4 to move behind the workstation, thus realizing a ground rail solution. Figure 5 , Figure 8 As shown; the second configuration is an inverted installation, in which the traveling mechanism 2 is located on the upper half of the compactor 4, suspending the compactor 4 to achieve movement behind the workstation, thus realizing the overhead rail solution, as shown. Figure 4 , Figure 6 , Figure 7 As shown; without changing the mechanical structure of the walking mechanism 2, the above two forms can meet the application requirements of the walking mechanism 2 in different schemes by different installation positions of the rollers and drive components of the walking mechanism 2.

[0042] The drive mechanism of the traveling mechanism 2 is not used for load-bearing; it only drives the movement. The load-bearing mechanism relies on the first roller 303 and the second roller 304 of the traveling mechanism 2, both of which are driven wheels. The drive of the traveling mechanism 2, i.e., X-axis movement, adopts a gear and rack meshing drive scheme to avoid positioning errors caused by the sliding friction of the brake rollers. An encoder is used to record the precise position of the traveling mechanism, and the encoder data is calibrated by proximity switches at each parking spot to ensure accurate positioning. The drive gear 302 transmits the torque of the drive reduction motor through a universal joint coupling, reducing the installation difficulty between the reduction motor 301 and the drive gear 302 and improving product reliability. The rack 701 is fixed inside the X-axis track beam of the steel structure, and the rotation of the drive gear 302 drives the traveling mechanism 2 to move in the X-axis direction. Figure 7 As shown;

[0043] The walking mechanism can adapt to different application requirements without changing the mechanical structure, using different installation positions of the walking wheels and drive unit. The modular design of the walking mechanism can reduce the production and inventory costs of materials, shorten the design and production cycle, and improve resource utilization efficiency.

[0044] The steel frame 1 provides overhead support for the walking mechanism 2 and the compactor 4. The walking mechanism 2 can drive the compactor 4 to move along the X-axis track assembly 7 inside the steel frame 1, so that the compactor 4 moves along the X-axis track assembly 7 in the X-axis direction. The first walking component 9 at the bottom of the outer wall of the compactor 4 can move along the second Y-axis track assembly 8 in the Y-axis direction, so that the compactor 4 can better exit from the walking mechanism 2 and enter the first Y-axis track assembly 6. The first walking component 9 at the bottom of the outer wall of the compactor 4 can move along the first Y-axis track assembly 6 in the Y-axis direction, so that the compactor 4 can move to the top of the transfer container, ensuring that the compactor 4 accurately compresses the waste in the transfer container.

[0045] The compression equipment area is further divided into a compression area in front of the berth and a travel area behind the berth. Before the compactor 4 travels to the station that needs to be compressed, it no longer needs to judge whether there is a collection vehicle unloading on the travel route, and can reach any berth to carry out compression operations.

[0046] The first traveling assembly 9 on the compactor 4, the second traveling assembly 3 on the traveling mechanism 2, the second Y-axis track assembly 8, the X-axis track assembly 7, and the first Y-axis track assembly 6 work together to enable the compactor 4 to travel in the X and Y directions on the compressor. Specifically, the compactor 4's movement between different berths is called X-axis movement; the compactor 4's movement from the rear traveling area to the front compression area is called Y-axis movement; and the compaction cylinder extending to drive the compactor 4 to compress vertically downwards after the compactor head reaches the predetermined position is called Z-axis compression. Figure 2 , Figure 3 As shown;

[0047] The process flow is as follows: After the transfer container is filled with garbage, ① the traveling mechanism 2 drives the compactor 4 to move along the track X direction to the back of the target container's workstation to wait for the compression command; ② the closed door between the unloading area and the traveling area is opened; ③ the compactor 4 moves along the track Y direction to the top of the target container; ④ the compactor 4's pressure head Z direction compresses the garbage inside the container; ⑤ the compactor 4 returns to the traveling area to wait for boxing or moves to other workstations that are full and need to be compressed for operation; ⑥ garbage is unloaded into the container again, and after it is full, it is compressed again (repeating the above steps ① to ⑤) until the garbage in the container reaches the designed loading capacity, and the unloading chute is retracted and the feed door at the top of the container is closed; the above steps ① to ⑤ are one-button operations, only issuing the workstation number command that needs to be compressed, and the equipment actions are all automatically controlled by the program;

[0048] To enable the compactor 4 to advance to the compression berth, the Y-axis track needs to be divided into two sections. One section is built into the track beam of the traveling mechanism 2 to ensure that the compactor 4 moves with the traveling mechanism 2 in the X-axis direction. The other section is fixed to the steel structure compression berth to ensure that the compactor 4 can detach from the traveling mechanism 2 and reach the compression berth. To ensure that the compactor 4 can smoothly advance to the compression berth, the positioning accuracy of the traveling mechanism 2 in the X-axis direction and the sufficient docking accuracy of the two Y-axis track sections must be guaranteed to be within a reliable range. The specific solution is as follows:

[0049] The drive mechanism of the walking mechanism 2 is driven by a variable frequency geared motor and equipped with an encoder. The walking mechanism 2 can perform actions such as "acceleration → constant speed → deceleration → braking" according to the travel distance. The walking speed is controllable and adjustable, and the operation is smooth, reliable, without jamming or slippage. It avoids equipment failure caused by inertial action due to sudden braking at high speeds, and improves the docking accuracy and precision of the Y-axis track inside the walking mechanism 2 and the Y-axis track of the steel structure.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
