Description

Technical Field

[0001] This invention belongs to the field of rolling technology, specifically relating to a rolling device for garbage truck side plates. Background Technology

[0002] The side panels of garbage trucks are key components of the truck body, typically working in conjunction with the front, rear, and floor panels to form the garbage loading cavity. These components are mostly made of high-strength steel or lightweight alloy materials, possessing impact resistance, wear resistance, and corrosion resistance. They can withstand the friction and compression during garbage loading, adapting to complex and harsh operating conditions. Currently, garbage truck side panels are generally manufactured using rolling mills.

[0003] Chinese patent CN120885564B discloses a garbage truck side plate rolling device, including a carrier plate. A power input mechanism is mounted on the upper surface of the carrier plate, and a transmission box is mounted on the upper surface of the carrier plate. The output end of the power input mechanism is fixedly connected to the input end of the transmission box. Two symmetrically arranged transmission rods are mounted on the output end of the transmission box, and a frame is fixedly connected to the upper surface of the carrier plate. In this invention, the material support mechanism can be started synchronously when the side plate is discharged. After one end of the side plate rests on the roller, the servo motor drives the slide and the stop block to move upward through the threaded rod, pressing the belt tightly against the inner wall of the through hole of the mounting block. The belt drive keeps the roller and the side plate discharge speed consistent, forming a continuous follow-up support, which can effectively support the discharged side plate, prevent the side plate from bending, warping and other deformations due to its own weight, and reduce the plate loss rate. It is especially suitable for the rolling processing of long garbage truck side plates.

[0004] However, in practical applications, the aforementioned technical solutions typically require adjustment of the spacing between the rolls to accommodate plates of varying thicknesses. Furthermore, the lifting and lowering of the rolls and their rotation drive often need to be synchronized. Therefore, existing technologies usually incorporate universal joints between the rolls and the drive unit to achieve transmission and prevent interference between their movements. However, existing universal joints are mostly exposed on the outside of the equipment, increasing the overall footprint and making their surfaces prone to accumulating metal shavings and other impurities, thus significantly shortening their service life. Summary of the Invention

[0005] The purpose of this invention is to provide a garbage truck side plate rolling device, which aims to solve the problem that the exposed transmission components of the equipment in the prior art lead to an increase in the overall size of the equipment and the overall floor space.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a garbage truck side plate rolling device, comprising a frame, an upper roll and a lower roll rotatably mounted on the frame, and a drive device disposed on one side of the frame. The frame includes two symmetrically arranged vertical plates, with the upper roll and the lower roll disposed between the two vertical plates. An adjusting plate is disposed on the vertical plates and slides on the vertical plates. The end of the upper roll is rotatably mounted on the adjusting plate. A drive assembly for driving the two adjusting plates to move up and down synchronously is also provided above the frame. A through hole is provided in the middle of the adjusting plate for a transmission component to pass through. The diameter of the through hole is larger than the diameter of the transmission component to provide sufficient clearance for the up and down movement of the adjusting plate. The output end of the drive device is directly connected to the lower roll, and a transmission component is provided between the drive device and the upper roll. The drive device drives the upper roll to rotate through the transmission component. A cavity is provided inside the upper roll, and the transmission component is disposed inside the cavity. One end of the transmission component is connected to the drive device, and the other end is connected to the upper roll.

[0007] A further technical solution of the present invention is that two cavities are provided, symmetrically distributed at the left and right ends of the upper roll, and the two cavities are isolated from each other, with the two cavities forming an opening at the end of the upper roll.

[0008] A further technical solution of the present invention is that the upper roll is provided with a disassembly structure inside, which is used to realize the detachable connection between the transmission component and the upper roll.

[0009] A further technical solution of the present invention is that the disassembly structure includes an installation hole opened inside the upper roll and an installation sleeve inserted into the installation hole. The installation hole is a blind hole and its open end faces the drive device. A keyway is opened on the inner wall of the installation hole, and a spline is provided on the installation sleeve to slide with the keyway. A rectangular shaft is fixedly provided at one end of the transmission component near the upper roll. A rectangular hole adapted to the shape of the rectangular shaft is opened inside the installation sleeve. The rectangular shaft is inserted into the rectangular hole and fixedly connected to the installation sleeve by bolts.

[0010] A further technical solution of the present invention is that the upper roller is also provided with a locking structure, which is used to restrict the axial sliding of the mounting sleeve in the mounting hole; the locking structure includes a locking groove opened at the opening end of the mounting hole, a locking tongue slidably disposed in the locking groove, and an elastic element that pushes the locking tongue to move towards the mounting hole; the locking tongue is in the shape of a right trapezoid, the inclined part of which extends into the mounting hole, and the inclined surface is inclined from top to bottom towards the direction close to the driving device; a pull rope is also connected to the locking tongue, the pull rope extends into the cavity and is connected to a pull ring, and pulling the pull rope can retract the locking tongue into the locking groove.

[0011] A further technical solution of the present invention is that the frame includes a base and two upright plates fixed on the base, with the two upright plates spaced apart to form an installation space, and the upper roller and the lower roller are both disposed between the two upright plates.

[0012] A further technical solution of the present invention is that each of the two vertical plates is provided with a sliding groove extending in the vertical direction, an adjusting plate is slidably arranged in the sliding groove, the end of the upper roller is rotatably mounted on the adjusting plate, and a driving assembly is also provided above the frame, the driving assembly being used to drive the two adjusting plates to move up and down synchronously along the sliding groove.

[0013] A further technical solution of the present invention is that an installation ring is provided on the side of the adjusting plate near the upper roller, a bearing is installed on the installation ring, an installation platform is provided at the opening of the cavity, and the outer ring of the bearing is installed on the installation platform, so that the upper roller is rotated and installed on the adjusting plate.

[0014] A further technical solution of the present invention is that the transmission component is a universal joint.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention provides a cavity inside the upper roll and houses the transmission component for connecting the drive device and the upper roll in the cavity, so that the transmission component no longer occupies extra space outside the equipment, significantly reducing the overall footprint of the rolling device, which is beneficial for the layout and installation of the equipment in narrow factory areas.

[0017] 2. This invention completely houses the transmission components within the cavity of the upper roll. The outer wall of the upper roll forms a physical barrier, effectively preventing metal shavings, dust, and coolant generated during rolling from splashing onto the surface of the transmission components. This significantly reduces the risk of wear, jamming, and corrosion caused by impurities, thereby significantly extending the service life of the transmission components and reducing equipment maintenance frequency and replacement costs. Furthermore, this cavity structure increases the heat dissipation area of ​​the upper roll, allowing it to dissipate heat to the surrounding environment more quickly during continuous high-speed rolling. This effectively suppresses temperature rise on the roll surface, reduces thermal fatigue and wear, and further improves the roll's durability and machining accuracy retention.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0027] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0029] Please see Figures 1-6 The present invention provides the following technical solution: a garbage truck side plate rolling device, including a frame 1, on which an upper roll 2 and a lower roll 3 are rotatably arranged, the upper roll 2 being adjustable up and down on the frame 1; a drive device 4 is also provided on one side of the frame 1, the output end of the drive device 4 being directly connected to the lower roll 3, and simultaneously connected to the upper roll 2 via a transmission component 5, so that the drive device 4 can simultaneously drive the upper roll 2 and the lower roll 3 to rotate, so as to roll the side plate.

[0030] Please see Figure 1 and Figure 2 The frame 1 includes a base 11 and two upright plates 12. Two upright plates 12 are provided, both mounted on the base 11, with a gap between them. The upper roller 2 and the lower roller 3 are both positioned between the two upright plates 12. Each upright plate 12 has a groove 13 extending upwards and downwards (see [reference]). Figure 4 The slide 13 has an adjusting plate 14 that slides inside it. The upper roller 2 is mounted on the adjusting plate 14 and can move up and down with the adjustment plate 14, thereby adjusting the distance between the upper roller 2 and the lower roller 3. The frame 1 also includes a drive assembly 6 above it, which drives the two adjusting plates 14 to move synchronously along the slide 13. Preferably, the drive assembly 6 can be a combination transmission structure of worm gear and lead screw, wherein the lead screw is rotatably connected to the upper part of the adjusting plate 14 and threadedly connected to the top plate above the frame 1. The worm gear is fixed above the lead screw, and a worm is engaged on one side of the worm gear. The worm is driven by a motor, so that the two lead screws can rotate synchronously and drive the two adjusting plates 14 to move up and down synchronously. The drive assembly 6 can also be a dual hydraulic cylinder synchronous drive structure. Since the drive assembly 6 is a known technology in the art, its specific structure will not be described in detail in this application.

[0031] Please see Figures 2-4 The upper roll 2 has two cavities 21 symmetrically distributed at its left and right ends, with flared openings at the ends. The two cavities 21 are isolated from each other, and their axial cross-section is I-shaped. The transmission component 5 is located inside the cavity 21 near the drive device 4 and is mounted on the inner bottom wall of the cavity 21. The other end of the transmission component 5 extends outward from the cavity 21 and connects to the drive device 4, allowing the drive device 4 to drive the upper roll 2 to rotate via the transmission component 5. The transmission component 5 is a universal joint. By placing the transmission component 5 inside the upper roll 2, the overall footprint of the equipment can be reduced. At the same time, the location of the transmission component 5 inside the upper roll 2 can prevent metal impurities or dust on the side plate from falling onto the transmission component 5, thus avoiding affecting the transmission performance of the transmission component 5. In addition, the cavity 21 inside the upper roll 2 increases its heat dissipation area, allowing the upper roll 2 to dissipate heat more quickly, reduce temperature rise, slow down wear, and extend service life.

[0032] Please see Figure 4 and Figure 6 An installation ring 141 is provided on the side of the adjusting plate 14 near the upper roller 2. A bearing 142 is installed on the installation ring 141. An installation platform is provided at the opening of the cavity 21. The outer ring of the bearing 142 is installed on the installation platform, so that the upper roller 2 can be installed on the adjusting plate 14 and can rotate stably on the adjusting plate 14.

[0033] The adjustment plate 14 has a through hole 143 in the middle. The transmission component 5 is connected to the drive device 4 and the upper roller 2 through the through hole 143. The diameter of the through hole 143 is larger than the diameter of the transmission component 5, so that the through hole 143 has a gap 1431 that allows the transmission component 5 to move inside.

[0034] Please see Figure 3 and Figure 5 A disassembly structure 7 is provided in the middle of the upper roll 2. This disassembly structure 7 facilitates quick assembly and disassembly of one end of the universal joint inside the upper roll 2. Specifically, it includes a mounting hole 71 opened inside the upper roll 2. The mounting hole 71 is a blind hole, with one open end facing the drive device 4. A mounting sleeve 72 is inserted into the mounting hole 71. The mounting sleeve 72 and the mounting hole 71 are clearance-fitted, allowing the mounting sleeve 72 to be inserted and removed inside the mounting hole 71. A keyway 73 is opened on the mounting hole 71, and the keyway 73 extends along the length of the mounting hole 71. The mounting sleeve 72 is provided with a spline 74 that can slide inside the keyway 73. The keyway 73 and spline 74 prevent relative rotation between the mounting sleeve 72 and the upper roller 2. A rectangular hole is provided inside the mounting sleeve 72. A rectangular shaft 75 that matches the shape of the rectangular hole is fixedly provided at one end of the transmission component 5. The rectangular shaft 75 is inserted into the rectangular hole and fixed inside the rectangular hole by bolts at the bottom of the mounting sleeve 72 to prevent the rectangular shaft 75 from moving axially inside the rectangular hole.

[0035] The upper roll 2 is also provided with a locking structure 8, which is used to limit the axial sliding of the mounting sleeve 72 in the mounting hole 71. The locking structure 8 specifically includes a locking groove 81 opened at the opening end of the mounting hole 71. The locking groove 81 extends radially along the mounting hole 71. A locking tongue 82 is slidably disposed in the locking groove 81. The locking tongue 82 is in the shape of a right-angled trapezoid, and a portion of its inclined surface extends upward into the mounting hole 71. The inclined surface slopes downward toward the direction close to the drive device 4. An elastic element 83 is provided in the locking groove 81 to push the locking tongue 82 toward the mounting hole 71. The elastic element 83 is a compression spring, one end of which is fixed inside the locking groove 81 and the other end of which is fixed on the locking tongue 82. A pull rope 84 is fixed below the locking tongue 82. A pull rope through hole is provided inside the upper roller 2. The through hole extends from the inside of the locking groove 81 to the cavity 21. The other end of the pull rope 84 passes through the through hole into the cavity 21 and is connected to a pull ring. The operator can pull the pull rope 84 by pulling the pull ring.

[0036] When assembling the transmission component 5 with the upper roll 2, first insert the rectangular shaft 75 into the rectangular hole and fix the rectangular shaft 75 and the mounting sleeve 72 together with bolts. Then, align the spline 74 with the keyway 73 and insert the mounting sleeve 72 into the mounting hole 71. At this time, one end of the mounting sleeve 72 presses against the inclined surface of the locking tongue 82, pushing the locking tongue 82 into the locking groove 81, so that it is completely retracted into the locking groove 81 and slides along the outer surface of the mounting sleeve 72. When the mounting sleeve 72 moves to the bottom of the mounting hole 71, the locking tongue 82 moves out of the mounting hole 71. One end of the sleeve 72 extends to the other end and, under the action of the elastic element 83, pops out towards the mounting hole 71, causing the locking tongue 82 to abut against the end of the mounting sleeve 72 and limit its axial direction, thereby preventing the mounting sleeve 72 from falling out of the mounting hole 71. When it is necessary to disassemble the transmission component 5, first pull the pull rope 84 to retract the locking tongue 82 into the locking groove 81, release the limitation on the mounting sleeve 72, and then the mounting sleeve 72 can be taken out from the mounting hole 71, thereby realizing the quick installation and disassembly of the upper roll 2, which is convenient for the maintenance and replacement of the roll.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
