Description

Technical Field

[0001] This invention relates to the field of garbage truck technology, specifically to a vibration-resistant lifting and tilting device for hook-lift garbage trucks. Background Technology

[0002] Hook-lift garbage trucks are widely used in urban sanitation waste collection operations. They rely on a lifting and tilting device to lift and unload garbage bins. They are widely used in urban communities, streets, and towns for domestic waste collection. Using a hydraulically driven lifting and tilting mechanism, they can automatically lift and tilt 120-240L standard plastic garbage bins and dump the garbage into the garbage truck compartment. This greatly reduces the labor intensity of sanitation workers and improves the efficiency of garbage collection and transportation. It is the mainstream collection and transportation equipment in the sanitation field.

[0003] However, existing hook-lift garbage truck lifting and dumping devices are relatively traditional, generally using a fixed speed to lift and tip the garbage bins, lacking adaptive speed adjustment based on load. In actual operation, for heavily loaded garbage bins or wet garbage containing sewage, the fixed operating speed easily leads to equipment shaking and severe garbage jolting, frequently resulting in garbage and sewage spillage. This not only causes secondary pollution on the road but also seriously reduces the stability and safety of garbage dumping operations. On the other hand, the core sprocket and chain drive structure of existing lifting devices is exposed to the elements for extended periods, easily accumulating dirt, debris, and other contaminants during operation. Traditional equipment lacks targeted automatic cleaning and lubrication protection structures, allowing debris to easily get stuck in the gaps between the sprockets and chains, causing transmission jamming, sluggish operation, and accelerated wear of parts. This not only increases the probability of equipment failure and subsequent maintenance costs but also significantly shortens the service life of the transmission mechanism. To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration-resistant lifting and dumping device for hanging garbage trucks to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vibration-resistant lifting and tilting device for a hanging garbage truck, comprising a mounting plate fixed to the right side of the garbage truck body, side frames fixed on both the left and right sides of the front of the mounting plate, a tilting mechanism disposed in a slide rail on one side opposite to the two side frames, a connecting block fixed to the rearward side of the tilting mechanism, a screw threadedly connected to the central circular hole of the connecting block, the upper section of the screw being slidably and rotatably connected to the front connecting piece above the mounting plate via a spring, a fixing plate mounted on the front side below the mounting plate, a rotating column rotatably connected to the front circular hole of the fixing plate, and the fixing... A three-gear assembly is rotatably connected to the rear circular hole on the plate. The top of the three-gear assembly is connected to the mounting plate via a motor. The lower section of the screw without a screw groove is slidably connected to the rotating column via a vertical groove. The bottom of the screw is connected to the bottom of the rotating column's inner cavity via a spring. A hydraulic rod is fixed at the center of the bottom of the rotating column's inner cavity. The output end of the hydraulic rod corresponds to the position of the bottom of the screw. An adjustment assembly is provided between the screw, rotating column, and three-gear assembly for adjusting the screw's rotational speed. A lubrication assembly is provided between the hydraulic rod, connecting block, and screw for lubricating and cleaning the screw.

[0006] Optionally, the tilting mechanism includes a sliding frame and a reversing frame. The upper end of the sliding frame is connected to two symmetrical protrusions on the rear side of the middle of the reversing frame via a rotating shaft. Both the sliding frame and the reversing frame are connected to the side frame slide rail via left and right side rotating wheels. The upper part of the side frame slide rail has an arc-shaped flipping section. The top of the front side plate of the reversing frame is used for insertion into the edge of the trash can. A limit rod is installed between the two symmetrical protrusions on the rear side of the upper part of the reversing frame via a motor rotation. A connecting block is fixed to the rear side of the sliding frame.

[0007] Optionally, the adjustment assembly includes a rotating tube rotatably mounted at the bottom of the inner cavity of the rotating column. A thinner tube above the rotating tube is connected to a screw via an inner spiral groove. Three abutting blocks are fixed at equal angles from top to bottom circumferentially on the outer side of the thinner tube above the rotating tube. Each abutting block is rotatably connected to a locking block. The three locking blocks are slidably mounted in a slide groove by spring limiting. The three slide grooves are horizontally connected and vertically arranged at corresponding positions on the upper section of the rotating column. The other end of each of the three locking blocks is inserted and connected to a driven gear ring. The three driven gear rings are rotatably mounted on the outer side of the upper section of the rotating column and are respectively engaged with the corresponding teeth of a three-gear combination.

[0008] Optionally, a protrusion is fixed on the outer side of the unthreaded section of the screw. The protrusion on the outer side of the screw is used to slide with the spiral groove on the inner side of the upper tube of the rotating tube. The height of the spiral groove on the inner side of the upper tube of the rotating tube corresponds to the height of the vertical groove in the lower section of the screw. The spiral groove on the inner side of the upper tube of the rotating tube is used for the rotating tube to rotate one revolution.

[0009] Optionally, all three abutting blocks are designed with the same arc-shaped structure, and the end faces of adjacent abutting blocks are on the same vertical horizontal plane. The inner sides of the three driven gear rings are designed with circumferential teeth, which are used for the insertion of the locking blocks. The two ends of the three locking blocks are designed with inclined surfaces. The diameter of the three driven gear rings increases sequentially from top to bottom, and the diameter of the outer teeth of the triple gear decreases sequentially from top to bottom.

[0010] Optionally, the lubrication assembly includes a connecting ring and a lubrication ring. The lubrication ring is fixed to the upper end of the connecting block, and the connecting ring is fixed to the outside of the lubrication ring by an outer protruding rod. The connecting ring has a liquid inlet chamber. Multiple sealing sliders are circumferentially and equidistantly installed in the liquid inlet chamber by means of springs. A cleaning block is installed below the multiple sealing sliders, penetrating the bottom section of the connecting ring and extending inward. A brush is provided on the inward side of each of the multiple cleaning blocks. The liquid inlet chamber is connected to the inner cavity of the hydraulic rod through a hose.

[0011] Optionally, the lubrication assembly also includes an oil reservoir formed within the lubrication ring. Multiple opening and closing strips are vertically and slidably passed through the oil reservoir by springs. The multiple opening and closing strips are circumferentially and equidistantly distributed within the oil reservoir. The number of opening and closing strips corresponds to the number of sealing sliders. The top inclined end of each opening and closing strip abuts against the bottom of the sealing slider. An immersion ring is fixed in the annular groove on the inner side of the bottom of the lubrication ring.

[0012] Optionally, each of the opening and closing strips has an opening below it, and the inner wall of the bottom annular groove of the lubrication ring has multiple openings circumferentially. The number of multiple openings on the inner wall of the bottom annular groove of the lubrication ring corresponds to the number of opening and closing strips. The opening below each opening and closing strip and the opening at the corresponding position on the inner wall of the annular groove of the lubrication ring are initially in a staggered and closed state.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention features adaptive speed adjustment based on load capacity, preventing spillage of garbage and wastewater. The device automatically adjusts the lifting and tipping speed according to the weight of the garbage bin. Through a gear switching structure linked by a screw under pressure, it achieves adaptive adjustment where the heavier the load, the slower the operating speed. For wastewater and heavy-duty garbage, it effectively reduces swaying and impact during lifting and tipping, preventing garbage and wastewater spillage caused by excessive operating speed, eliminating secondary pollution, and significantly improving the stability and safety of garbage dumping operations.

[0014] This invention features automatic cleaning and lubrication under heavy loads, extending the service life of the mechanism. The equipment has a heavy-load triggered self-cleaning and self-lubricating function. When the garbage bin is under heavy load and the compression spring reaches its limit, a hydraulic linkage structure drives the cleaning slider to slide against the screw, automatically cleaning dirt, debris, and garbage from the screw surface. This prevents debris from getting stuck in the threaded connection, causing jamming and wear. Simultaneously, the lubrication structure activates, automatically releasing lubricating fluid to evenly lubricate the rotating parts of the screw, effectively reducing frictional wear on components under heavy loads, decreasing the probability of equipment failure, and lowering subsequent maintenance costs.

[0016] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0017] Please see Figures 1 to 10This invention provides a technical solution: a shock-resistant lifting and tilting device for a hanging garbage truck, comprising a mounting plate 1 fixed to the right side of the garbage truck body, side frames 2 fixed on both the left and right sides of the front of the mounting plate 1, a tilting mechanism provided in the slide rail on the opposite side of the two side frames 2, a connecting block 5 fixed to the rear side of the tilting mechanism, the tilting mechanism including a sliding frame 3 and a reversing frame 4, the upper end of the sliding frame 3 being connected to two symmetrical protrusions on the rear side of the middle of the reversing frame 4 via a rotating shaft, both the sliding frame 3 and the reversing frame 4 being connected to the slide rail of the side frame 2 via left and right rotating wheels, the upper part of the reversing section of the slide rail of the side frame 2 having an arc-shaped structure, the front side of the reversing frame 4 near the top of the plate for inserting the garbage bin rim, placing the garbage bin on the mounting plate 1, and pushing the garbage bin... When the sliding frame 3 is raised, the reversing frame 4 rises together with it. The concave and convex plates at the upper end of the reversing frame 4 are engaged with the flange of the garbage can opening. A limit rod 41 is installed between the two symmetrical protrusions on the upper rear side of the reversing frame 4 through the rotation of the motor. The limit rod 41 is flipped under the drive of the motor and fastened to both sides of the garbage can opening. The reversing frame 4 lifts the garbage can that is fixed. When the sliding frame 3 and the reversing frame 4 rise, the wheels on both sides of them slide in the slide of the side frame 2. When the wheels of the reversing frame 4 are raised to the arc-shaped structure of the flipping section above the side frame 2, the reversing frame 4 deflects because the reversing frame 4 and the sliding frame 3 are connected by a shaft mechanism, causing the garbage can to flip and dump the garbage in the garbage can.

[0018] A connecting block 5 is fixed to the rear side of the sliding frame 3. A screw 6 is threadedly connected to the central circular hole of the connecting block 5. When the screw 6 rotates, the connecting block 5 fitted on it is lifted by the twisting of the thread. The upper section of the screw 6 is slidably and rotatably connected to the front connecting piece above the mounting plate 1 by a spring. A fixing plate 8 is installed on the front side below the mounting plate 1. A rotating column 7 is rotatably connected to the front circular hole of the fixing plate 8. A triple gear 9 is rotatably connected to the rear circular hole of the fixing plate 8. The top of the triple gear 9 is connected to the mounting plate 1 through a motor. The lower section of the screw 6 without a threaded groove is slidably connected to the rotating column 7 through a vertical groove. The bottom of the screw 6 is connected to... The bottom of the inner cavity of the rotating column 7 is connected by a spring. When the reversing frame 4 lifts the trash can, the weight of the trash can is transferred to the screw 6. The screw 6 is supported by the spring and will descend to different degrees according to the weight of the trash can. An adjustment component 10 is provided between the screw 6, the rotating column 7 and the triple gear 9. The adjustment component 10 is used to adjust the speed of the screw 6. The triple gear 9 drives three driven gear rings 105 of different sizes to rotate, which drives the screw 6 to rotate at different speeds. A lubrication component 12 is provided between the hydraulic rod 11, the connecting block 5 and the screw 6. The lubrication component 12 is used for lubricating and cleaning the screw 6.

[0019] In one embodiment of the present invention, the adjustment assembly 10 includes a rotating tube 101, which is rotatably installed at the bottom of the inner cavity of the rotating column 7. The thinner tube body above the rotating tube 101 is connected to the screw 6 through an inner spiral groove. Three abutting blocks 102 are fixed at equal angles from top to bottom circumferentially on the outer side of the thinner tube body above the rotating tube 101. The lower section of the screw 6 without a spiral groove slides down along the rotating column 7 and presses down through the outer protrusions to squeeze the inner spiral groove of the rotating tube 101. Since the rotating tube 101 is rotatably connected to the rotating column 7, when the inner spiral groove is subjected to downward pressure, the rotating tube 101 will rotate with the downward pressure of the screw 6, causing the abutting blocks 102 on its outer wall to rotate. In one embodiment of the present invention, each abutment block 102 is rotatably connected to a locking block 103. All three locking blocks 103 are slidably mounted in a slide groove 104 by spring limiting. The three slide grooves 104 are horizontally connected and vertically arranged at corresponding positions on the upper section of the rotating column 7. The other end of each of the three locking blocks 103 is inserted into a driven gear ring 105. The three driven gear rings 105 are rotatably mounted on the outer side of the upper section of the rotating column 7, and respectively mesh with the corresponding teeth of the triple gear 9. When the locking block 103 engages with its corresponding driven gear ring 105, the rotating column 7 is driven to rotate by the driven gear ring 105. All three abutment blocks 102 are designed with the same arc-shaped structure, and the end faces of adjacent abutment blocks 102 are on the same vertical horizontal plane. The inner sides of the three driven gear rings 105 are designed with circumferential teeth for the locking blocks 103 to insert into. The three locking blocks 103 are designed with inclined surfaces at both ends. The diameters of the three driven gear rings 105 increase from top to bottom, while the diameters at the outer teeth of the triple gear 9 decrease from top to bottom. After the uppermost contact block 102 rotates and separates from the locking block 103, the uppermost locking block 103 slides along the slide groove 104 under the action of the spring and separates from its corresponding driven gear ring 105. At this time, the lower contact block 102 rotates to its corresponding locking block 103 and presses the inclined sliding surface on it. The locking block 103 is engaged in the inner teeth of its corresponding driven gear ring 105. At this time, the rotating column 7 and the screw 6 are driven to rotate by the driven gear ring 105. Since the size of the driven gear rings 105 is arranged from small to large, under the drive of the triple gear 9, the speed of each driven gear ring 105 gradually decreases from top to bottom, so that the screw 6 lifts and tilts the garbage can at different speeds depending on the weight of the garbage can.

[0020] In one embodiment of the present invention, a hydraulic rod 11 is fixed at the center of the bottom of the inner cavity of the rotating column 7. The upper output end of the hydraulic rod 11 corresponds to the bottom position of the screw 6. The lubrication assembly 12 includes a connecting ring 121 and a lubrication ring 122. The lubrication ring 122 is fixed to the upper end of the connecting block 5. The connecting ring 121 is fixed to the outside of the lubrication ring 122 by an outer protruding rod. An inlet chamber 123 is provided in the connecting ring 121. Multiple sealing sliders 124 are circumferentially and equidistantly installed in the inlet chamber 123 by springs. Cleaning blocks 125 are installed on the inner side of the bottom section of the connecting ring 121 below the multiple sealing sliders 124. Brushes are provided on the inner side of the multiple cleaning blocks 125. The inlet chamber 123 is open to... The hose is connected to the inner cavity of the hydraulic rod 11. When the weight of the trash can causes the spring below the screw 6 to be compressed to the maximum extent, as the unthreaded section of the screw 6 is pressed down, the lowest locking block 103 engages with its corresponding driven toothed ring 105, and the rotation speed of the screw 6 reaches its slowest. During this process, the lower end of the screw 6 presses against the contact end of the hydraulic rod 11, forcing the oil in the hydraulic rod 11 through the hose into the inlet chamber 123 of the connecting ring 121. As the oil is injected, the sealing sliders 124 of the circumferential array on the connecting ring 121 are pushed by the oil and slide along the slide towards the screw 6, causing the cleaning block 125 to apply greater pressure to the screw 6 and sweep off the dirt, debris and other substances with strong adhesion to its surface.

[0021] In one embodiment of the present invention, the lubrication assembly 12 further includes an oil storage cavity 128 formed within the lubrication ring 122. Multiple opening and closing strips 126 are vertically and slidably disposed within the oil storage cavity 128 via springs. The multiple opening and closing strips 126 are circumferentially and equidistantly distributed within the oil storage cavity 128. The number of opening and closing strips 126 corresponds to the number of sealing sliders 124. The top inclined end of each opening and closing strip 126 abuts against the bottom of the sealing slider 124. An immersion ring 127 is fixed within the annular groove on the inner side of the bottom of the lubrication ring 122. An opening is formed below each opening and multiple openings are formed circumferentially on the inner wall of the annular groove at the bottom of the lubrication ring 122. The number of openings on the inner wall corresponds to the number of opening and closing strips 126. The opening below each opening and closing strip 126 is initially staggered and closed with the opening at the corresponding position on the inner wall of the annular groove of the lubrication ring 122. When the blocking slider 124 moves, its lower end presses the inclined sliding surface at the top of the opening and closing strip 126, causing the opening and closing strip 126 to move down in the lubrication ring 122. The staggered openings of the opening and closing strip 126 and the lubrication ring 122 coincide when it moves down. The lubricating fluid in the oil storage chamber 128 overflows from the opening and wets the wetting ring 127. As the screw 6 rotates, the wetting ring 127 attached to the screw 6 applies the lubricating fluid to the surface of the screw 6, so as to lubricate and protect the lifting mechanism when the lifting weight is too large.

[0022] Working principle: When using the lifting and dumping device of the hook-lift garbage truck, first place the garbage can on the mounting plate 1, push the garbage can to make it fit with the reversing frame 4, and when the screw 6 rotates, the connecting block 5 on it is lifted by the twisting of the thread, and the sliding frame 3 slides upward along the slide of the side frame 2. When the sliding frame 3 is lifted, the reversing frame 4 rises together with it. The concave and convex plates at the upper end of the reversing frame 4 are engaged with the flange of the garbage can opening. At the same time, the limiting rod 41 is flipped under the drive of the motor and is fixed on the top two sides of the garbage can opening. The reversing frame 4 lifts the fixed garbage can. When the sliding frame 3 and the reversing frame 4 rise, the rotating wheels on both sides slide in the slide of the side frame 2. When the rotating wheels of the reversing frame 4 are lifted to the arc-shaped structure slide of the flipping section above the side frame 2, since the reversing frame 4 and the sliding frame 3 are connected by the shaft mechanism, the reversing frame 4 deflects, causing the garbage can to flip and dump the garbage in the garbage can. During the aforementioned lifting process, in the initial state, the locking block 103 on the rotating column 7 is supported by the uppermost abutment block 102 and inserted into its corresponding driven gear ring 105. The driven gear ring 105 is driven by the triple gear 9 meshing with it, causing the rotating column 7 to rotate on the fixed plate 8. The screw 6 rotates together with the rotating column 7. When the reversing frame 4 lifts the trash can, the weight of the trash can is transferred to the screw 6. The screw 6 is supported by a spring and will descend to different degrees according to the weight of the trash can. The lower section of the screw 6 without a screw groove slides down along the rotating column 7 and presses down, and squeezes the inner spiral groove of the rotating tube 101 through the outer protrusion. Since the rotating tube 101 is rotatably connected to the rotating column 7, when the inner spiral groove is subjected to the downward force, the rotating tube 101 will rotate with the downward pressure of the screw 6, causing the abutment block 102 on its outer wall to rotate. After the abutment block 102 rotates and separates from the locking block 103, the uppermost locking block 103 slides along the slide groove 104 under the action of spring reset and separates from its corresponding driven gear ring 105. At this time, the lower abutment block 102 rotates to its corresponding locking block 103 and presses the inclined sliding surface on it. The locking block 103 is locked into the inner tooth of its corresponding driven gear ring 105. At this time, the rotating column 7 and the screw 6 are driven to rotate by the driven gear ring 105. Since the size of the driven gear ring 105 is arranged from small to large, under the drive of the triple gear 9, the speed of each driven gear ring 105 gradually decreases from top to bottom. This achieves that the screw 6 lifts and tilts the garbage can at different speeds depending on the weight of the garbage can, preventing the garbage can from being too heavy, especially sewage garbage, from spilling garbage and sewage during the lifting and tilting process.

[0023] During the above process, when the weight of the trash can causes the spring below the screw 6 to compress to its maximum extent, as the unthreaded section of the screw 6 is pressed down, the lowest locking block 103 engages with its corresponding driven gear ring 105, and the rotational speed of the screw 6 reaches its slowest point. During this process, the lower end of the screw 6 presses against the contact end of the hydraulic rod 11, forcing the oil in the hydraulic rod 11 through the hose into the inlet chamber 123 of the connecting ring 121. As the oil is injected, the sealing sliders 124 of the circumferential array on the connecting ring 121 are pushed by the oil and slide along the slide towards the screw 6, causing the cleaning block 125 to apply greater force to the screw 6. The pressure is applied to the screw 6 and removes dirt and debris from its surface, preventing them from entering the connection between the screw 6 and the connecting block 5. At the same time, when the blocking slider 124 moves, its lower end presses against the inclined sliding surface at the top of the opening and closing strip 126, causing the opening and closing strip 126 to move downward within the lubrication ring 122. The misaligned openings of the opening and closing strip 126 and the lubrication ring 122 coincide when it moves downward, and the lubricating fluid in the oil storage chamber 128 overflows from the opening to wet the wetting ring 127. As the screw 6 rotates, the wetting ring 127, which is attached to the screw 6, applies the lubricating fluid to the surface of the screw 6, thereby achieving lubrication protection for the lifting mechanism when the lifting weight is too large.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
