Description

Technical Field

[0001] This utility model relates to waste collection and belongs to the field of logistics and transfer, specifically to a space transfer device for underground waste collection bins. Background Technology

[0002] Underground garbage collection bins are garbage collection facilities that are set up underground, with only the disposal opening remaining on the ground. They have advantages such as hiding garbage containers, optimizing space utilization, and preventing garbage exposure, and can significantly improve the hygiene, aesthetics, and convenience of underground garbage collection points.

[0003] The common method for transferring underground garbage collection bins is as follows: the bins are first collected at underground collection points. When transferring, a transport vehicle travels underground to the collection point, where a hooklift truck removes the bin. During the transfer, the transport vehicle inevitably needs to turn and make U-turns, requiring a large transfer space and being constrained by the underground pipeline network. Alternatively, some garbage collection bins have their own drive mechanisms to move between the underground collection point and the transfer point, reducing the need for transport vehicles to enter underground. However, this structure results in high manufacturing costs and limited load-bearing capacity / volume, and the drive mechanism is easily damaged during transfer. In particular, when the distance between the underground collection point and the transfer point is too large, the travel time of the garbage collection bin increases, resulting in low transfer efficiency and poor flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a space transfer device for underground garbage collection bins, which can transfer the collection bins horizontally and vertically. It occupies little space, avoids the need for transfer vehicles to enter from underground, and the mobile vehicle body moves synchronously with the mobile vehicle body. It is low-cost, more flexible, and effectively improves transfer efficiency.

[0005] To achieve the above objectives, the underground waste collection bin space transfer device includes:

[0006] The collection box is driven to move between the underground collection point and the underground lifting point;

[0007] The mobile vehicle is located below the collection box and actively moves between the underground collection point and the underground lifting point. The mobile vehicle has a positioning component that extends and connects to the lower end of the collection box. Under the action of the positioning component, the collection box can move synchronously with the mobile vehicle.

[0008] The lifting mechanism has a pair of lifting plates that are driven to move synchronously, and the lifting plates move vertically between the underground lifting point and the ground lifting point;

[0009] A pair of lifting plates are arranged perpendicular to the direction of movement of the collection box;

[0010] The gap between the pair of lifting plates is larger than the outer contour of the moving vehicle body but smaller than the lower outer contour of the collection box, so that the pair of lifting plates can support the area below the collection box.

[0011] In some examples of this utility model, the mobile vehicle body has:

[0012] The drive unit has a dual-output shaft structure;

[0013] The drive wheel is fixedly connected to the dual output ends of the drive component via the first shaft.

[0014] The first shaft is rotatably mounted on the support plate via bearings.

[0015] In some examples of this utility model, the lower end of the collection box is provided with a positioning plate having positioning holes;

[0016] The positioning component is fixedly located at the upper end of the support plate, including:

[0017] Telescopic components are installed on the upper part of the mobile vehicle body;

[0018] The positioning rod is fixedly connected to the output end of the telescopic component. Under the action of the telescopic component, the positioning rod can be inserted into the positioning hole of the positioning plate.

[0019] In some examples of this utility model, the two ends of the first shaft are respectively rotatably mounted on the lower end of the support plate via bearings;

[0020] The first end cap and the second end cap are installed on both sides of the first shaft body, and correspondingly form a sealed first cavity and a sealed second cavity;

[0021] The first cavity is provided with a first oil nozzle, and the second cavity is provided with a second oil nozzle.

[0022] In some examples of this utility model, a plurality of fixing blocks are fixedly arranged at the lower end of the collection box;

[0023] A second shaft is fixed on the fixed block, and a roller is rotatably mounted on each second shaft;

[0024] The second shaft is provided with a first hole arranged along the axis, closed at one end and open at the other end and connected to the third oil nozzle;

[0025] The second shaft has a radially arranged second hole that communicates with the first hole.

[0026] In some examples of this utility model, the lifting mechanism also includes a plurality of vertically arranged support columns, a support slider that rolls on the support columns, and a lifting motor mounted on the support columns;

[0027] The lifting motor drives the support slider to move on the support column via a transmission rope;

[0028] The lifting plate is fixedly connected to the supporting slider.

[0029] In some examples of this utility model, a transfer point is provided at the extension of the line connecting the underground collection point to the underground lifting point;

[0030] There are multiple collection boxes, which are located between the waiting point and the underground lifting point;

[0031] The mobile vehicle can move between the waiting point and the underground lifting point.

[0032] In some examples of this utility model, the mobile vehicle is equipped with sensors for locating underground collection points, underground lifting points, and transfer points;

[0033] The sensor can transmit signals to the controller, which then controls the positioning components and the moving vehicle to move.

[0034] In some examples of this utility model, a negative pressure mechanism is provided at the ground lifting point;

[0035] When the collection box is raised to the ground lifting point, the controller controls the negative pressure mechanism to generate negative pressure.

[0036] Compared with existing technologies, this underground waste collection container space transfer device achieves both horizontal and vertical transfer of the collection container because the mobile vehicle located below can move synchronously between the underground collection point and the underground lifting point, and the lifting mechanism can move the collection container vertically between the underground lifting point and the ground lifting point. It occupies less space overall and avoids the need for transfer vehicles to enter underground. In addition, the synchronous movement of the mobile vehicle is cost-effective and more flexible, effectively improving transfer efficiency.

[0037] Because there is a transfer point at the extension of the line connecting the underground collection point to the underground lifting point, empty collection boxes can be moved to the transfer point. When the collection box is lifted away from the underground lifting point, the mobile vehicle can move laterally to the left to the transfer point and move the corresponding collection box to the underground collection point. This can reduce the blank time at the underground collection point and improve the efficiency of garbage collection and transfer. Attached Figure Description

[0052] like Figures 1 to 3 , Figure 5 As shown, the underground waste collection bin space transfer device includes:

[0053] Collection box 10 is driven to move between the underground collection point and the underground lifting point;

[0054] The mobile vehicle 20 is located below the collection box 10 and actively moves between the underground collection point and the underground lifting point. The mobile vehicle 20 has a positioning component that extends and connects to the lower end of the collection box 10. Under the action of the positioning component, the collection box 10 can move synchronously with the mobile vehicle 20.

[0055] The lifting mechanism has a pair of lifting plates 43 that are driven to move synchronously, and the lifting plates 43 move vertically between the underground lifting point and the ground lifting point;

[0056] A pair of lifting plates 43 are arranged perpendicular to the moving direction of the collection box 10;

[0057] Among them, the gap between the pair of lifting plates 43 is greater than the outer contour of the moving vehicle body 20 and smaller than the lower outer contour of the collection box 10, so that the pair of lifting plates 43 can support the area below the collection box 10.

[0058] Specifically, for ease of description, we will use the following example: the collection box 10 and the mobile vehicle 20 move horizontally left and right. The underground collection point is located on the right side of the horizontal movement. The underground lifting point is indicated as the lifting position on the first underground floor, and the ground lifting point is indicated as the lifting position on the first floor above ground.

[0059] During the civil construction phase, a concrete platform is reserved on the first basement floor to form the base 30. Holes are reserved at the ground lifting point. The outside of the holes is a closed structure with opening and closing doors to facilitate the transfer of transport vehicles. The base 30 is equipped with horizontally arranged inner and outer double tracks 50. The inner track 50 is used for the movement of the mobile vehicle 20, and the outer track 50 is used for the movement of the collection box 10, making the movement smoother.

[0060] The collection box 10 is a box structure with one end that can be opened and closed to allow garbage to enter; the mobile vehicle 20 moves below the collection box 10 to avoid collisions; the lifting mechanism has a lifting plate 43 that is driven to move up and down, and the movement is located between the underground lifting point and the ground lifting point;

[0061] When the underground garbage collection bin space transfer device is in use, a compaction device 60 can be installed at the underground collection point. The compaction device 60 can compact the garbage to reduce the space occupied.

[0062] Initially, the collection box 10 is located at the underground collection point, and the lifting plate 43 in the lifting mechanism is located at the bottom and is lower than the bottom of the collection box 10. The garbage is put in from the ground floor and can be compacted by the compaction device 60 and pushed into the collection box 10. When the garbage in the collection box 10 reaches a certain weight, the mobile vehicle 20 moves to the bottom of the collection box 10, the positioning component is activated, and the connection between the collection box 10 and the mobile vehicle 20 is completed.

[0063] The mobile vehicle 20 moves the collection box 10 laterally to the left to the underground lifting point, and the positioning component is disconnected from the collection box 10; the lifting mechanism is activated, and the lifting plate 43 is driven to move upward, first passing the mobile vehicle 20 and then contacting the lower end of the collection box 10, and then lifting the collection box 10 to the ground lifting point.

[0064] The rear of the transfer vehicle moves to the ground lifting point, and the collection box 10 is transported away by the hook-lift truck. Similarly, the transfer vehicle can place the empty collection box 10 at the ground lifting point by the hook-lift truck. The lifting mechanism drives the empty collection box 10 down to the underground lifting point. The moving vehicle body 20 then moves the empty collection box 10 laterally to the right to the underground collection point, waiting for the next collection.

[0065] In some examples of this utility model, such as Figure 3 As shown, the mobile vehicle body 20 has:

[0066] Drive component 21 has a dual output shaft structure;

[0067] The drive wheel 23 is fixedly connected to the dual output ends of the drive component 21 via the first shaft 22;

[0068] The first shaft 22 is rotatably mounted on the support plate 24 via a bearing;

[0069] Specifically, the drive component 21 is a dual-output shaft motor, with both ends connected to the drive wheel 23 via the first shaft 22. The drive component 21 can be connected to a controller, which automatically controls the start of the drive component 21. The first shaft 22 drives the corresponding drive wheel 23 to rotate synchronously, thereby realizing the lateral movement of the moving vehicle body 20. Note that the drive wheel 23 is matched with the inner track 50 on the base 30.

[0070] In some examples of this utility model, such as Figure 3 , Figure 5 As shown, the lower end of the collection box 10 is provided with a positioning plate 12 having positioning holes;

[0071] The positioning component is fixedly located at the upper end of the support plate 24, including:

[0072] Telescopic component 25 is installed on the upper end of the mobile vehicle body 20;

[0073] The positioning rod 26 is fixedly connected to the output end of the telescopic component 25. Under the action of the telescopic component 25, the positioning rod 26 can be inserted into the positioning hole of the positioning plate 12.

[0074] Specifically, the positioning plate 12 can be an angle steel, and the angle steel has a positioning hole with a size slightly larger than that of the positioning rod 26;

[0075] The telescopic component 25 can be a telescopic rod with dual-axis output and can be controlled by a controller. When the telescopic component 25 is started, its output end will drive the positioning rod 26 to move longitudinally, thereby inserting it into the positioning hole to achieve positioning.

[0076] Additionally, a positioning sleeve 27 can be fixed on the support plate 24, and the positioning rod 26 can slide within the positioning sleeve 27 to ensure the stability of the positioning rod 26's movement.

[0077] In some examples of this utility model, such as Figure 4 As shown, the two ends of the first shaft 22 are rotatably mounted on the lower end of the support plate 24 via bearings;

[0078] The first end cap and the second end cap are installed on both sides of the first shaft 22, and correspondingly form a sealed first cavity 221 and a second cavity 223;

[0079] The first cavity 221 is provided with a first oil nozzle 222, and the second cavity 223 is provided with a second oil nozzle 224;

[0080] Specifically, a pair of spaced supports can be fixed at the lower end of the support plate 24. The first shaft 22 is rotatably connected to the support by means of shaft shoulder, collar, etc. The drive wheel 23 is located between the pair of supports, and a sealing structure is provided between the support and the first shaft 22.

[0081] Due to the underground environment, the rotating bearing between the first axle 22 and the drive wheel 23 is prone to wear during long-term load-bearing and movement of the mobile vehicle body 20, which reduces the movement effect of the mobile vehicle body 20.

[0082] Operators can periodically inject lubricating oil into the first cavity 221 and the second cavity 223 through the first grease nipple 222 and the second grease nipple 224 respectively. The lubricating oil can be stored to ensure sufficient lubrication of the bearing.

[0083] In some examples of this utility model, such as Figure 2 As shown, the lifting mechanism also includes a plurality of vertically arranged support columns 41, a support slider 42 that rolls on the support columns 41, and a lifting motor mounted on the support columns 41.

[0084] The lifting motor drives the support slider 42 to move on the support column 41 via the transmission rope;

[0085] The lifting plate 43 is fixedly connected to the supporting slider 42;

[0086] Specifically, there can be four support columns 41, which are vertically arranged in four positions. The support slider 42 is equipped with pulleys, and the pulleys are limited and installed on the support columns 41.

[0087] As one embodiment of the lifting method, the output end of the lifting motor is connected to a drum, and the support column 41 is provided with multiple guide wheels. One end of the traction rope is connected to the support slider 42, and the other end is wrapped around the outside of the guide wheel and connected to the drum. Multiple lifting motors operate synchronously, and the support slider 42 and the lifting plate 43 are lifted by winding / unwinding the transmission rope through the drum.

[0088] As another embodiment of the lifting, the output end of the lifting motor is connected to a gear, the upper and lower ends of the support column 41 are respectively provided with guide wheels, the traction rope is a chain structure, and one end of the rope is connected to the upper end of the support slider 42, and the other end is successively wrapped around the outside of the upper guide wheel and the lower guide wheel before being connected to the lower end of the support slider 42. At the same time, the gear is meshed with the traction rope.

[0089] The lifting motor can be connected to the controller, and the controller can start the lifting motor to make multiple lifting plates 43 move synchronously.

[0090] In some examples of this utility model, such as Figure 6 As shown, a plurality of fixing blocks 14 are fixedly arranged at the lower end of the collection box 10;

[0091] A second shaft 13 is fixed on the fixed block 14, and a roller 11 is rotatably mounted on each second shaft 13;

[0092] The second shaft 13 is provided with a first hole 131 arranged along the axis, closed at one end and open at the other end and connected to the third oil nozzle 133;

[0093] The second shaft 13 is provided with a second hole 132 arranged radially and communicating with the first hole 131;

[0094] Specifically, in this example, the lubricant is used to lubricate the lower roller 11 of the collection box 10. The lubricant enters from the third oil nozzle 133 into the first hole 131 and exits from the second hole 132, so that the roller 11 and the second shaft 13 are filled with lubricant to avoid damage caused by dry friction between the roller 11 and the second shaft 13 for a long time.

[0095] In some examples of this utility model, such as Figure 1 As shown, a transfer point is provided at the extension of the line connecting the underground collection point to the underground lifting point;

[0096] There are multiple collection boxes (10 in total), which are located between the waiting point and the underground lifting point.

[0097] Specifically, a transfer point is set on the left side of the underground lifting point, and the collection box 10 and the mobile vehicle 20 can move smoothly between the transfer point, the underground lifting point, and the underground collection point.

[0098] When the collection box 10 is lifted away from the underground lifting point, there is no collection box 10 at the underground collection point for garbage collection. Therefore, the mobile vehicle 20 can move laterally to the left to the waiting point and be located below the corresponding collection box 10. Under the action of the positioning component, the collection box 10 moves to the underground collection point.

[0099] Similarly, the empty collection box 10 at the ground lifting point can be transferred to the waiting point via the lifting mechanism and the mobile vehicle 20;

[0100] In this example, by setting up a transfer point, the additional collection box 10 can be temporarily stored at the transfer point and moved to the underground collection point in a timely manner, which can reduce the blank time at the underground collection point and improve the efficiency of garbage collection and transfer.

[0101] In some examples of this utility model, the mobile vehicle body 20 is equipped with sensors for locating underground collection points, underground lifting points, and transfer points;

[0102] The sensor can transmit signals to the controller, and after receiving the signals, the controller controls the movement of the positioning component and the moving vehicle 20.

[0103] Specifically, the sensor can be a photoelectric sensor. When the mobile vehicle 20 moves to the underground collection point, underground lifting point, or waiting point, it can identify the collection box 10 at the corresponding location and use the positioning hole on the collection box 10 as a reference for positioning. For example, when the mobile vehicle 20 moves to the underground collection point, the photoelectric sensor identifies the collection box 10 at that location, the controller controls the mobile vehicle 20 to stop moving, and the positioning component on the mobile vehicle 20 can match the positioning hole to complete the positioning of the positioning rod 26 and the positioning hole.

[0104] Alternatively, a vision sensor can be installed on the mobile vehicle body 20 to assist in adjusting the position of the mobile vehicle body 20.

[0105] In some examples of this utility model, a negative pressure mechanism is provided at the ground lifting point;

[0106] When the collection box 10 is raised to the ground lifting point, the controller controls the negative pressure mechanism to generate negative pressure;

[0107] Specifically, a hole is reserved in the floor slab of the lifting mechanism. The outside of the hole is a closed structure with an opening and closing door. When the opening and closing door is opened, in order to prevent the garbage odor from overflowing, the controller controls the negative pressure mechanism to start. At this time, the air pressure inside the hole is lower than that outside.

[0108] The above description, with reference to preferred embodiments, details an exemplary implementation of the underground garbage collection bin space transfer device proposed by this utility model. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this utility model, and various combinations can be made to the various technical features and structures proposed by this utility model without exceeding the protection scope of this utility model, which is determined by the appended claims.
