Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, specifically a rail-mounted garbage truck. Background Technology

[0002] In the daily operation of a city, waste disposal is a crucial task that requires efficient execution. As key equipment for waste collection and transportation, the performance of garbage trucks affects the environmental sanitation quality of the entire city. With the continuous expansion of urban scale and the continuous growth of population, the amount of waste generated is increasing day by day, which puts forward higher requirements for the working efficiency and safety of garbage trucks.

[0003] Currently, mainstream garbage trucks on the market suffer from numerous problems that urgently need to be addressed. Most existing garbage trucks can only empty one garbage bin at a time. When multiple bins at a garbage collection point typically require emptying, this design forces the truck to operate on each bin individually, significantly increasing collection time and reducing work efficiency. Furthermore, each time garbage is dumped, it lands in the same spot on the truck, easily leading to uneven garbage accumulation. This wastes the truck's internal storage space, reducing its loading capacity, and may also affect the vehicle's stability. In addition, during the dumping and lifting process, the lack of reliable securing and protective measures poses a risk of garbage bins falling, potentially damaging the bins and surrounding facilities, and also threatening the safety of operators and pedestrians. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rail-mounted garbage truck that solves the problems of low efficiency in existing garbage trucks, which require emptying one bin at a time and operating one bin at a time; uneven accumulation of garbage in the same place, affecting load capacity and stability; and bins not being reliably fixed during lifting, which can easily fall off and endanger safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rail-mounted garbage truck, comprising two rail vertical beams and a fixed shaft. A lifting assembly is provided between the upper ends of the two rail vertical beams. Both ends of the fixed shaft slide longitudinally through the interior of the two rail vertical beams, and a garbage bin lifting plate for lifting garbage bins is provided on the exterior of the fixed shaft between the two rail vertical beams. An anti-detachment mechanism for fixing the garbage bins is provided on the garbage bin lifting plate. A rack is provided on one edge of each of the two rail vertical beams, and the rack is higher than the side plate of the vehicle body. A traveling mechanism is provided on the rear side of each of the two rail vertical beams and is mounted on the side plate of the vehicle body. Both ends of the fixed shaft are provided with gears adapted to the racks. Limiting sleeves are rotatably fitted on the exterior of both ends of the fixed shaft inside the rail vertical beams, and torsion springs are fitted on the exterior of both ends of the fixed shaft. The two ends of the torsion springs are respectively connected to the limiting sleeves and one side of the gears.

[0006] Preferably, when the gear moves upward, it passes through the position of the traveling mechanism and engages with it.

[0007] Preferably, the limiting sleeve is provided with T-shaped blocks on both the front and rear sides, and the inner sides of the track vertical beam are provided with T-shaped grooves that are adapted to the T-shaped blocks, and the T-shaped blocks are slidably disposed in the T-shaped grooves.

[0008] Preferably, the lifting assembly includes a limiting shaft rotatably disposed between the upper ends of the two track beams, and a lifting servo motor installed on one side of the upper end of one of the track beams to drive the rotation of the limiting shaft. Both ends of the limiting shaft are provided with winding wheels inside the two track beams, and steel wire ropes are wound on the winding wheels. One end of the steel wire ropes is connected to the limiting sleeve.

[0009] Preferably, the traveling mechanism includes an L-shaped locking block disposed on the rear side of the track vertical beam, the L-shaped locking block being fitted onto the side panel of the vehicle body, and a traveling motor being installed on the side of the L-shaped locking block away from the track vertical beam. The output shaft of the traveling motor is located inside the L-shaped locking block and connected to a traveling wheel, which is slidably disposed on the upper side of the side panel of the vehicle body.

[0010] Preferably, the trash can lifting plate includes two limiting plates that are respectively fixedly sleeved on the outside of both ends of the fixed shaft. The two limiting plates are located between two track vertical beams, and a plate body is vertically arranged between one end of the two limiting plates. A plurality of protrusions for hanging the trash can are equidistantly arranged on the upper side of the plate body. When the torsion spring is in the reset state, the plate body is in the vertical state.

[0011] Preferably, the anti-detachment mechanism includes a long strip plate hinged to the upper part of one side of the plate body, an L-shaped strip corresponding to each protrusion on the upper side of the long strip plate, the upper end of the L-shaped strip being located above the corresponding protrusion, a raised strip being provided at the upper edge of one side of the long strip plate, and the anti-detachment mechanism also includes a hydraulic cylinder installed on one side of the plate body, the output shaft of the hydraulic cylinder being hinged to a connecting rod, and the other end of the connecting rod being hinged to one end of the raised strip.

[0019] 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.

[0020] Please see Figures 1-3 This utility model provides three technical solutions:

[0021] Example 1

[0022] Please see Figures 1-2In this embodiment of the utility model, a rail-mounted garbage truck includes two rail vertical beams 1 and a fixed shaft 3. A lifting assembly 2 is provided between the upper ends of the two rail vertical beams 1. The two ends of the fixed shaft 3 slide longitudinally through the interior of the two rail vertical beams 1, and a garbage bin lifting plate 4 for lifting garbage bins is provided on the outside of the fixed shaft 3 between the two rail vertical beams 1. An anti-detachment mechanism 5 for fixing garbage bins is provided on the garbage bin lifting plate 4. A rack 6 is provided on one side edge of each of the two rail vertical beams 1. The rack 6 is higher than the side plate of the vehicle body. A traveling mechanism 7 is provided on the rear side of each of the two rail vertical beams 1. The traveling mechanism 7 is installed on the side plate of the vehicle body. A gear 8 adapted to the rack 6 is provided at both ends of the fixed shaft 3. A limiting sleeve 9 is rotatably sleeved on the outside of both ends of the fixed shaft 3 inside the rail vertical beam 1. A torsion spring 10 is sleeved on the outside of both ends of the fixed shaft 3. The two ends of the torsion spring 10 are respectively connected to the limiting sleeve 9 and one side of the gear 8.

[0023] Please see Figures 1-2 In this embodiment of the present invention, when the gear 8 moves upward, it will pass through the position of the walking mechanism 7 and mesh with it.

[0024] In the above scheme: after the trash can is fixed, the lifting component 2 drives the trash can lifting plate 4 to lift. When the gear 8 moves to the position of the rack 6, the rack 6 will cause the gear 8 to rotate clockwise, thereby causing the trash can lifting plate 4 to rotate the trash can, allowing the trash inside the trash can to be poured into the vehicle.

[0025] For further details, please refer to Figures 1-2 In this embodiment of the utility model, T-shaped blocks 11 are provided on both the front and rear sides of the limiting sleeve 9, and T-shaped grooves adapted to the T-shaped blocks 11 are provided on both sides of the inner side of the track vertical beam 1. The T-shaped blocks 11 are longitudinally slidably disposed in the T-shaped grooves, which play a limiting role for the limiting sleeve 9.

[0026] For further details, please refer to [link / reference]. Figure 1 In this embodiment of the present invention, the lifting assembly 2 includes a limiting shaft 21 rotatably disposed between the upper ends of two track beams 1, and a lifting servo motor 22 installed on one side of the upper end of one of the track beams 1 to drive the rotation of the limiting shaft 21. Both ends of the limiting shaft 21 are provided with winding wheels inside the two track beams 1, and steel wire ropes are wound on the winding wheels. One end of the steel wire rope is connected to the limiting sleeve 9. The lifting servo motor 22 drives the winding wheels at both ends of the limiting shaft 21 to rotate. The winding wheels cause the steel wire rope to be unwound or wound up, which enables the garbage bin lifting plate 4 to move longitudinally, making it convenient to tilt the garbage bin.

[0027] For further details, please refer to Figure 1 and Figure 3In this embodiment of the utility model, the garbage bin lifting plate 4 includes two limiting plates 41 respectively fixedly sleeved on the outside of both ends of the fixed shaft 3. The two limiting plates 41 are located between the two track vertical beams 1, and a plate body 42 is vertically arranged between one end of the two limiting plates 41. A plurality of protrusions 43 for hanging garbage bins are equidistantly arranged on the upper side of the plate body 42. When the torsion spring 10 is in the reset state, the plate body 42 is in the vertical state. When a fully loaded garbage bin is hung on the plate body 42, the elastic force of the torsion spring 10 is greater than the weight of the garbage bin, so that the plate body 42 can still be in the vertical state, so that the garbage bin will not tip over during lifting.

[0028] Example 2 differs from Example 1 in that:

[0029] Please see Figure 1 In this embodiment of the utility model, the walking mechanism 7 includes an L-shaped locking block 71 disposed on the rear side of the track vertical beam 1. The L-shaped locking block 71 is fitted onto the side plate of the vehicle body, and a walking motor 72 is installed on the side of the L-shaped locking block 71 away from the track vertical beam 1. The output shaft of the walking motor 72 is located inside the L-shaped locking block 71 and connected to a walking wheel 73. The walking wheel 73 is slidably disposed on the upper side of the side plate of the vehicle body. By driving the walking wheel 73 to rotate through the walking motor 72, the device can be driven to move on the vehicle and change the position of garbage dumping.

[0030] Example 3 differs from Example 1 in that:

[0031] Please see Figure 1 and Figure 3 In this embodiment of the present invention, the anti-detachment mechanism 5 includes a long strip 51 hinged to the upper part of one side of the plate 42. The upper side of the long strip 51 is provided with an L-shaped strip 52 corresponding to each protrusion 43. The upper end of the L-shaped strip 52 is located above the corresponding protrusion 43. A protruding strip 53 is provided at the upper edge of one side of the long strip 51. The anti-detachment mechanism 5 also includes a hydraulic cylinder 54 installed on one side of the plate 42. The output shaft of the hydraulic cylinder 54 is hinged to a connecting rod 55. The other end of the connecting rod 55 is hinged to one end of the protruding strip 53.

[0032] In the above scheme: the trash can is moved to the position of the trash can lifting plate 4, and then the lifting servo motor 22 drives the winding wheels at both ends of the limit shaft 21 to rotate. The winding wheels cause the wire rope to be unloaded, and under the gravity of the trash can lifting plate 4, it moves downward. Then the hydraulic cylinder 54 drives the connecting rod 55 to move, and the connecting rod 55 drives the long strip plate 51 to rotate downward, so that the upper end of the L-shaped strip 52 leaves the position of the protrusion 43 on the plate body 42. Then the trash can is hung on the protrusion 43 on the plate body 42. By setting multiple protrusions 43 on the plate body 42, multiple trash cans can be hung at one time. After hanging, the hydraulic cylinder 54 is activated to make the long strip plate 51 rotate upward, so that the upper end of the L-shaped strip 52 presses on the upper edge of the trash can, which plays a role in fixing the trash can.

[0033] Working principle: The trash can is moved to the position of the trash can lifting plate 4. Then, the lifting servo motor 22 drives the winding wheels at both ends of the limit shaft 21 to rotate. The winding wheels cause the wire rope to be unloaded. Under the gravity of the trash can lifting plate 4, it moves downward. Then, the hydraulic cylinder 54 drives the connecting rod 55 to move. The connecting rod 55 drives the long plate 51 to rotate downward, so that the upper end of the L-shaped strip 52 is away from the protrusion 43 on the plate 42. Then, the trash can is hung on the protrusion 43 on the plate 42. Multiple trash cans can be hung at one time by setting multiple protrusions 43 on the plate 42. After hanging, the hydraulic cylinder 54 is activated to make the long plate 51 rotate upward, so that the upper end of the L-shaped strip 52 presses on the upper edge of the trash can, which plays a role in fixing the trash can.

[0034] After the trash can is fixed, the lifting component 2 drives the trash can lifting plate 4 to lift. When the gear 8 moves to the position of the rack 6, the rack 6 will cause the gear 8 to rotate clockwise, thereby causing the trash can lifting plate 4 to rotate the trash can, so that the trash can can be poured into the vehicle. The walking motor 72 drives the walking wheel 73 to rotate, which can drive the device to move on the vehicle and change the position of the trash dumping.

[0035] When the lifting assembly 2 moves the trash can lifting plate 4 downward, the rack 6 will cause the gear 8 to rotate counterclockwise, returning the trash can lifting plate 4 to its initial position. Under the elasticity of the torsion spring 10, the trash can lifting plate 4 will not continue to rotate downward in the initial position, preventing the trash can from rotating downward when it is being lifted.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
