Description

Technical Field

[0001] This invention relates to the field of sound barriers, and in particular to an automatic assembly device for sound barriers. Background Technology

[0002] On highways, urban elevated roads, and other roads, sound barriers are often used to reduce noise pollution caused by vehicles. The main components of a typical sound barrier include H-beams and plates. During construction, the H-beams are fixed to the concrete guardrails cast along the roadside, and then the sound insulation plates are stacked one after another between two H-beams from top to bottom until a complete sound insulation facade is formed.

[0003] Existing sound barrier assembly typically involves using cranes or lifting equipment to move the sound insulation panels to the top of the H-beams, then adjusting the panels' orientation so they can be vertically inserted between the two H-beams. However, this assembly method has many drawbacks: On the one hand, the sound insulation panels cannot automatically adjust their posture after being hoisted into the air. They need to be manually adjusted during the lowering process, which is not only inconvenient but also poses certain safety hazards, resulting in low overall assembly efficiency.

[0004] On the other hand, when using the hoisting method, after the upper and lower sound insulation panels are stacked, the hoisting tools or ropes are pressed between the two sound insulation panels, making it difficult to remove them and affecting the overall ease of installation. If they are pulled out directly, they are also very likely to damage the sound insulation panels, resulting in poor overall assembly efficiency and reliability. Summary of the Invention

[0005] This invention provides an automatic assembly device for sound barriers. The device clamps and fixes the sound insulation panels using a flipping frame, and the flipping frame can be used to adjust the sound insulation panels between horizontal and vertical positions. This solves the problems of poor installation convenience and low assembly efficiency in the assembly process of sound insulation panels in the prior art.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: An automatic assembly device for a sound barrier includes: a base, the base being connected to a flipping frame via a lifting device, and a driving component for flipping the flipping frame; the flipping frame is connected to a clamping mechanism for clamping and fixing sound insulation panels, and the sound insulation panels can be adjusted between horizontal and vertical positions by flipping the frame, and the lifting device is used to drive the flipping frame to move in the vertical direction to assemble the sound insulation panels between two H-beams.

[0007] As a preferred embodiment of the present invention, the clamping mechanism includes a drive assembly and a clamping frame connected to the flipping frame; the clamping frame is generally U-shaped and includes a connecting part connected to the back side of the flipping frame and a clamping part located on the front side of the flipping frame; the drive assembly is used to drive the connecting part of the clamping frame to move away from the flipping frame, and to use the clamping part to move towards the flipping frame, so as to clamp and fix the sound insulation panel on the flipping frame.

[0008] As a preferred embodiment of the present invention, a connecting column is fixedly connected to the back side of the flipping frame, and the connecting part of the clamping frame is movably inserted and connected to the connecting column, so as to drive the connecting part to rotate through the driving component, thereby adjusting the position of the clamping frame.

[0009] In a preferred embodiment of the present invention, the driving assembly includes an end face cam rotatably connected to the connecting column; the connecting part is fixedly connected to a bushing that mates with the connecting column, and the end face shape of the bushing matches the end face shape of the end face cam; the circumferential surface of the connecting column is provided with an L-shaped channel, the L-shaped channel including a limiting groove arranged along the axial direction of the connecting column and a guide groove arranged along the circumferential direction of the connecting column, and the guide groove and the limiting groove are connected at the end near the flipping frame, so that the guide groove and the limiting groove form an L-shaped structure; the bushing is fixedly connected to a... The L-shaped groove is used to fit the limiting guide post. The connecting post is fitted with an elastic element. One end of the elastic element abuts against the connecting part and is used to push the connecting part towards the flipping frame, so that the end face of the bushing is in close contact with the end face of the end face cam. When the limiting guide post is engaged with the guide groove, the end face cam rotates to drive the clamping frame to rotate synchronously. When the limiting guide post rotates to the limiting groove position, the rotation of the clamping frame is restricted. At this time, the end face cam continues to rotate, which drives the bushing to move axially, that is, drives the clamping frame to move as a whole, so as to realize the clamping action.

[0010] As a preferred embodiment of the present invention, the drive assembly further includes a driven gear fixedly connected to the outer wall of the end face cam, a slider slidably connected to the flipping frame, and a telescopic drive component fixedly connected to the flipping frame, wherein the slider is fixedly connected to a rack meshing with the driven gear.

[0011] As a preferred embodiment of the present invention, the flipping frame is rotatably connected to at least one rotating shaft, and is fixedly connected to a driving device that is connected to the rotating shaft for transmission; the rotating shaft is fixedly connected to a support plate, which is used to support and limit the sound insulation panel through the support plate, and drives the support plate to rotate toward the back side of the flipping frame through the rotating shaft, thereby releasing the support of the sound insulation panel.

[0012] As a preferred embodiment of the present invention, the lifting device is connected to a bracket, the bracket is slidably connected to two connecting arms, and a telescopic drive component is fixedly connected to drive the connecting arms to move; the tilting frame is hinged to the connecting arms, and a telescopic device is connected between the tilting frame and the connecting arms, which is used to drive the tilting frame to tilt relative to the connecting arms through the telescopic device, and to adjust the position of the tilting frame by using the movement of the connecting arms.

[0013] As a preferred embodiment of the present invention, the bracket is fixedly connected to a support shaft that is rotatably connected to the lifting device, and the driving component is connected to the support shaft in a transmission manner.

[0014] As a preferred embodiment of the present invention, it also includes an in-vehicle platform, and the base is slidably connected to the in-vehicle platform.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a clamping mechanism on a flipping frame to clamp and fix the sound insulation panel, and flips the frame to adjust the sound insulation panel between horizontal and vertical positions. A lifting device is used to move the flipping frame vertically, so that the sound insulation panel can be quickly assembled between two H-beams, which effectively improves the overall assembly convenience and efficiency.

[0017] 2. This invention adapts the end face shape of the bushing to the end face shape of the end face cam, allowing the end face cam to drive the clamping frame to rotate synchronously, thereby changing the position of the clamping frame and avoiding positional interference during material handling and installation. Furthermore, when the limiting guide post rotates to the limiting groove position, the rotation of the clamping frame is restricted. At this time, the end face cam continues to rotate, driving the bushing to move axially, which in turn drives the entire clamping frame to move, thus clamping the sound insulation panel. This improves the fixing effect of the sound insulation panel without affecting the positional interference caused by the clamping frame during installation, effectively improving the overall practicality and assembly reliability.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1 On major traffic arteries such as highways and urban elevated roads, sound barriers are key facilities for reducing traffic noise pollution. Their main structure typically consists of two H-beams pre-fixed to concrete guardrails and sound-insulating panels stacked layer upon layer between the two H-beams. Current assembly methods often involve using cranes or lifting equipment to hoist the sound-insulating panels to the top of the H-beams, then manually adjusting the panels' orientation from horizontal to vertical before inserting them into the flange grooves of the two H-beams from top to bottom.

[0022] This traditional assembly method has two significant technical drawbacks: First, once the soundproofing panels are hoisted into the air, their posture cannot be automatically adjusted. They rely entirely on manual pushing, pulling, and straightening at height, which is not only extremely inconvenient but also poses safety hazards to workers, such as falls and being crushed by the panels. The overall assembly efficiency is also low. Second, when one panel is stacked on top of another, the hoisting equipment or ropes are tightly pressed between the two panels, making removal extremely difficult. Forcibly pulling them out can easily scratch or damage the anti-corrosion layer or sound-absorbing material on the surface of the soundproofing panels, causing product quality damage. This affects both the soundproofing effect and reduces the overall installation reliability and aesthetics.

[0023] like Figure 1 , Figure 2 and Figures 6 to 8 As shown, in order to solve the above-mentioned technical problems, the present invention provides an automatic assembly device for a sound barrier, including a base 1, a lifting device, a flipping frame 2, and a clamping mechanism.

[0024] The base 1 serves as the supporting foundation for the entire device, and a tilting frame 2 is connected to it via a lifting device. The tilting frame 2 can move up and down in a wide range in the vertical direction under the drive of the lifting device. The lifting device can be a telescopic boom or a double-column lift, or other existing devices capable of lifting and lowering the tilting frame 2.

[0025] A drive unit 101 for driving the tilting frame 2 to tilt is also connected between the tilting frame 2 and the lifting device. A clamping mechanism is connected to the tilting frame 2 for firmly clamping and fixing the sound insulation panel 6.

[0026] Its working process and principle are as follows: Figure 3 , Figure 6 and Figure 8 As shown, at the material handling station, the flipping frame 2 is in a horizontal position. After the sound insulation panel 6 is pushed onto the flipping frame 2, the clamping mechanism firmly clamps and fixes a sound insulation panel 6 to the upper surface of the flipping frame 2.

[0027] Subsequently, as Figure 4 , Figure 5 , Figure 14 and Figure 17 As shown, the drive unit 101 drives the tilting frame 2 to rotate 90 degrees, changing it from a horizontal to a vertical position, and the sound insulation panel 6 also becomes vertical. Then, the lifting device lifts the tilting frame 2, which is in a vertical position, together with the sound insulation panel 6, to directly above the two H-beams, and slowly lowers it, vertically and smoothly inserting the sound insulation panel 6 between the two H-beams, completing its stacking with the previously installed sound insulation panel 6. Throughout the entire process, construction personnel do not need to directly touch or adjust the sound insulation panel 6 in the air.

[0028] It should be emphasized that the core improvement of this embodiment lies in the construction of an automated assembly device that integrates flipping and lifting functions. The flipping frame 2 automatically converts the horizontal posture of the sound insulation panel 6 during loading to its vertical posture during installation, and the lifting device completes precise positioning and placement. This completely changes the traditional high-altitude manual assistance operation mode, solving the engineering pain points of difficult posture adjustment of sound insulation panels, low installation efficiency, and potential safety hazards, and achieving safe, efficient, and high-quality mechanized automated assembly.

[0029] It should be noted that, in order to prevent the clamping mechanism from interfering with the position of the H-beam during material handling and installation, the clamping mechanism includes a drive assembly connected to the flipping frame 2 and a clamping frame 3.

[0030] like Figures 6 to 9 As shown, the clamping frame 3 has an overall U-shaped structure, including a connecting part 301 located on the back side of the flipping frame 2 (i.e., the side of the flipping frame 2 facing away from the H-beam when it is in a vertical position) and a clamping part 302 located on the front side of the flipping frame 2 (i.e., the side of the flipping frame 2 facing the H-beam when it is in a vertical position).

[0031] The drive assembly can drive the connecting part 301 of the clamping frame 3 to move away from the flipping frame 2, thereby causing the clamping part 302 to move towards the flipping frame 2, ultimately firmly clamping and fixing the sound insulation panel 6 onto the flipping frame 2. This clamping method, which pulls from the back, ensures that the clamping part 302 only needs to contact the sound insulation panel 6 at the edge of the flipping frame 2, without occupying too much space on the front side of the flipping frame 2. This ensures that most of the front surface area of ​​the sound insulation panel 6 is exposed, facilitating its smooth entry into the flange groove of the H-beam and improving the stability of the sound insulation panel during flipping and assembly.

[0032] Example 2 Understandably, in the first embodiment, the clamping part 302 of the clamping frame 3 is located on the front side of the flipping frame 2 when clamped, fixing the sound insulation panel 6. However, the position of the clamping frame 3 is not always the optimal choice during material handling and installation. For example, when the flipping frame 2 is horizontally handling material from the rack, if the clamping part 302 is above the flipping frame 2, it will prevent the sound insulation panel 6 from falling onto the surface of the flipping frame 2 from above, or from moving horizontally onto the flipping frame 2; while when the flipping frame 2 is vertically placing the panel downwards, if the clamping part 302 is below or to the sides of the flipping frame 2, it may collide and interfere with the flanges of the H-beam. Therefore, the circumferential position of the clamping frame 3 needs to be flexibly adjustable to adapt to the space requirements of different working stages.

[0033] To address the aforementioned issues of adjusting the circumferential position of the clamping frame and avoiding interference, such as... Figures 9 to 11 and Figure 13 As shown, in this embodiment, the clamping frame 3 is designed as a rotatable and adjustable structure. A connecting column 201 is fixedly connected to the back side of the flipping frame 2, and a bushing 303 is fixed on the connecting part 301 of the clamping frame 3. The bushing 303 is movably sleeved on the connecting column 201. By driving the connecting part 301 to rotate around the connecting column 201 through the driving assembly, the circumferential position of the clamping frame 3 can be flexibly adjusted.

[0034] Its working process is as follows: Figure 3 , Figure 6 and Figure 8 As shown, during the material handling stage, the drive assembly drives the clamping frame 3 to rotate, positioning its clamping part 302 at both sides of the flipping frame 2, thus creating space for the sound insulation panel 6 to fall onto the flipping frame 2. After the sound insulation panel 6 is pushed onto the flipping frame 2 from the horizontal direction, the drive assembly drives the clamping frame 3 to rotate, causing its clamping part 302 to rotate to the same side of the flipping frame 2 (i.e., the upper side when the flipping frame 2 is in a vertical position, such as...). Figures 13 to 17 (As shown).

[0035] Thus, as Figure 4 and Figure 5 As shown, during the subsequent lifting and installation process, the clamping part 302 only applies clamping force above the tilting frame 2. It will not interfere with the flange of the H-beam at any position, nor will it conflict with the installed sound insulation panel 6.

[0036] It should be emphasized that the core improvement of this embodiment is that the clamping frame 3 is designed to be rotatable around the connecting column 201, so that its clamping part 302 can flexibly change its circumferential position in different working stages. This not only meets the requirement of unobstructed material dropping during material picking, but also avoids the problem of interference with H-beams during installation, which significantly improves the adaptability of the device to working conditions and the flexibility of operation.

[0037] Understandably, the clamping frame 3 in this embodiment needs to perform two different actions: first, circumferential rotation around the connecting column 201 to change its position; and second, axial movement along the connecting column 201 to clamp and release the sound insulation panel 6. If separate drive devices are configured for these two actions, not only will the structure of the flipping frame 2 become bulky and complex, but the timing control of the two actions will also be prone to errors. A more ingenious design approach is to use the same drive source to sequentially complete the rotation and axial movement actions according to a preset mechanical logic.

[0038] To address the combined driving and timing issues of the aforementioned rotation and clamping actions, such as... Figure 9 , Figure 10 , Figure 11 and Figure 18 As shown, this embodiment provides a linkage mechanism for an end face cam 202. Specifically, the driving component includes an end face cam 202 rotatably connected to a connecting post 201. A bushing 303 that mates with the connecting post 201 is fixedly connected to the connecting part 301, and its end face shape is machined into a curved surface that matches the end face shape of the end face cam 202.

[0039] like Figure 13 , Figure 15 and Figure 18 As shown, the drive assembly also includes a driven gear 206 fixedly connected to the outer wall of the end face cam 202, a slider 207 slidably connected to the tilting frame 2, and a telescopic drive component 208 (which may be a cylinder, hydraulic cylinder, or electric push rod, etc.) fixedly connected to the tilting frame 2. The slider 207 is fixedly connected to a rack 209 that meshes with the driven gear 206.

[0040] An L-shaped groove is formed on the circumferential surface of the connecting column 201. This groove consists of two sections: a limiting groove 203 arranged along the axial direction of the connecting column 201, and a guide groove 204 arranged along the circumferential direction of the connecting column 201. The guide groove 204 communicates with the end of the limiting groove 203 near the tilting frame 2. A limiting guide post 304 is fixedly connected to the bushing 303. The end of the limiting guide post 304 is embedded in the L-shaped groove, serving as a constraint on movement. An elastic element 205 (such as a compression spring) is also fitted on the connecting column 201. One end of the elastic element 205 abuts against the connecting part 301, constantly applying a thrust pointing in the direction of the tilting frame 2.

[0041] Its working process and principle are as follows: Rotation phase: In the initial state, such as Figure 9 , Figure 10 , Figure 13 and Figure 16As shown, the limiting guide post 304 is located within the guide groove 204. When the telescopic drive component 208 drives the rack 209 to move, and drives the end face cam 202 to rotate via the driven gear 206, the limiting guide post 304, constrained by the guide groove 204, can only move in the circumferential direction and cannot move axially. At this time, under the action of the elastic component 205, the end face of the bushing 303 is in close contact with the end face of the end face cam 202, and the rotational torque of the end face cam 202 is transmitted to the bushing 303 through end face engagement, causing the clamping frame 3 to rotate synchronously around the connecting post 201, thus completing the adjustment of the circumferential position.

[0042] Clamping stage: such as Figure 11 , Figures 14 to 18 As shown, when the clamping frame 3 rotates to the predetermined position, the limiting guide post 304 just reaches the intersection of the guide groove 204 and the limiting groove 203. At this time, the circumferential rotation of the clamping frame 3 is blocked by the side wall of the limiting groove 203 and cannot continue to rotate. The end face cam 202 continues to rotate, and the curved surface profile of its end face begins to slide relative to the end face of the bushing 303. During this process, since the clamping frame 3 cannot rotate, the end face cam 202 forcibly pushes the bushing 303 and the entire clamping frame 3 to move along the axial direction of the connecting post 201 in a direction away from the flipping frame 2. This axial movement causes the clamping part 302 to move closer to the flipping frame 2, that is, to move towards the flipping frame 2, thereby clamping the sound insulation panel 6.

[0043] Release phase: The end face cam 202 rotates in the reverse direction, and the elastic force of the elastic element 205 pushes the end face of the bushing 303 to always be in close contact with the end face of the end face cam 202, causing the clamping frame 3 to move axially towards the flipping frame 2 to reset, and the clamping part 302 is released. When the limiting guide post 304 retracts into the guide groove 204, the end face cam 202 continues to rotate in the reverse direction, which can drive the clamping frame 3 to rotate in the reverse direction to reset.

[0044] It should be emphasized that the core improvement of this embodiment lies in the innovative mechanical linkage between the end face cam 202 and the L-shaped channel, perfectly realizing the sequential action of first rotating into position and then axially clamping through purely mechanical logic. A single drive source solves the coupling and decoupling problem between the two actions of clamping frame position adjustment and clamping force application. The structure is extremely ingenious, the action logic is reliable, and no complex electrical control is required.

[0045] Example 3 Understandably, in the clamping mechanism of Embodiment 2, the sound insulation panel 6 is clamped and fixed on the flipping frame 2. During the flipping process of the flipping frame 2 from a horizontal to a vertical position, and during lifting and lowering installation in a vertical position, the sound insulation panel 6 is mainly subjected to the frontal pressing force of the clamping part 302. However, the direction of gravity changes during the flipping process, especially when approaching a vertical position, where most of the weight of the sound insulation panel 6 acts on its lower end. If there is no additional support at the lower end, the sound insulation panel 6 risks sliding downwards. Relying solely on the friction between the clamping part 302 and the panel surface to resist all the gravity is unreliable; once slippage occurs, it will not only lead to installation positioning failure but may also damage the panel.

[0046] To address the issues of reliable support and anti-slip properties of the sound insulation panel 6 during the aforementioned flipping process, such as... Figure 7 , Figure 8 and 12 As shown, in this embodiment, a rotatable tray support mechanism is added to the lower end of the flipping frame 2. Specifically, at least one rotating shaft 210 is rotatably connected to the flipping frame 2. In this embodiment, taking the attached figure as an example, there are two rotating shafts 210.

[0047] Each rotating shaft 210 is fixedly connected to a support plate 212. A drive device 211, which is connected to the rotating shaft 210, is fixedly connected to the tilting frame 2. The drive device 211 can be a cylinder or a hydraulic cylinder. A gear is fixedly connected to the rotating shaft 210. A guide rod is slidably connected to the tilting frame 2 through a bracket and a linear bearing. Both ends of the guide rod are fixedly connected to cylindrical racks that mesh with the gears. The guide rod is fixedly connected to the telescopic end of the drive device 211. Thus, the drive device 211 drives the guide rod bearing to move, which in turn drives the rotating shaft 210 to rotate through the two cylindrical racks.

[0048] Its working process is as follows: Figure 8 As shown, during the material handling and flipping stage, the drive device 211 drives the rotating shaft 210 to rotate, so that the pallet 212 is in an upright state, that is, its supporting plane faces the front of the flipping frame 2. At this time, the pallet 212 and the front of the flipping frame 2 together form an L-shaped support structure.

[0049] like Figure 15 and Figure 16 As shown, after the sound insulation panel 6 is clamped, its lower edge rests precisely on the support plate 212, with the support plate 212 bearing most of the weight. The clamping part 302 only needs to provide auxiliary anti-tipping force, greatly improving the reliability of the fixation. When the sound insulation panel 6 is installed in place and the assembly device needs to be removed, the drive device 211 drives the rotating shaft 210 to rotate and tilt the support plate 212 towards the back of the flipping frame 2, thereby releasing the bottom support of the sound insulation panel 6 and allowing the flipping frame 2 to be smoothly pulled out from the back of the installed sound insulation panel 6.

[0050] It should be emphasized that the core improvement of this embodiment is that a flip-up tray is added to the flipping frame, which provides reliable bottom physical support for the sound insulation panel, so that the panel has a place to land and something to support it during posture changes and lifting, fundamentally eliminating the risk of slipping due to gravity. The structure is simple and the support is reliable.

[0051] Example 4 It is understandable that in the above embodiments, when the tilting frame 2 delivers the sound insulation panel 6 to the top of the H-beam and begins its descent for installation, the sound insulation panel 6 needs to be precisely placed into the flange slots of the two H-beams. However, in addition, the assembly device itself may also produce positioning errors during movement and lifting. If the tilting frame 2 and the lifting device are rigidly connected, there will be no room for fine-tuning. Once a misalignment occurs, the sound insulation panel 6 will not be able to smoothly enter the slots, and forcibly pressing it down will cause damage to the sound insulation panel 6 or the H-beam.

[0052] To solve the problems of precise alignment and fine-tuning in the installation process, such as Figures 6 to 8 and Figure 13 As shown, this embodiment provides a flexible adaptive adjustment mechanism. A bracket 4 is connected to the top of the lifting device, and two connecting arms 401 are slidably connected on the bracket 4, as well as a telescopic drive component 402 (hydraulic cylinder or electric push rod) that drives the connecting arms 401 to move, which is fixedly connected to the bracket.

[0053] The bracket 4 is fixedly connected to a support shaft 404 that is rotatably connected to the lifting device, and the drive member 101 is connected to the support shaft 404 in a transmission manner. The drive member 101 drives the support shaft 404 to rotate, thereby causing the bracket 4 to flip.

[0054] The two sides of the tilting frame 2 are hinged to the front ends of the two connecting arms 401 respectively. A telescopic device 403 (cylinder or hydraulic cylinder) is also connected between the tilting frame 2 and the connecting arms 401.

[0055] The working process is as follows: When the sound insulation panel 6 descends close to the top of the H-beam, if a positional deviation is detected, the construction personnel can control the telescopic drive component 402 to activate, driving the connecting arm 401 to finely adjust the tilting frame 2 and the sound insulation panel 6 relative to the bracket 4 in the front-to-back direction. Simultaneously, after the tilting frame 2 is tilted into position, the telescopic device 403 can also perform fine-tuning of the pitch angle. These two sets of adjustment degrees of freedom allow the sound insulation panel 6 to adaptively find the entrance to the H-beam flange groove, achieving a flexible and unobstructed smooth entry into the groove.

[0056] It should be emphasized that the core improvement of this embodiment is that the combination of the sliding connecting arm 401 and the hinge structure provides two key degrees of freedom for the tilting frame 2: translation and pitch fine adjustment. This solves the problem of precise alignment caused by installation errors and makes the assembly process smoother and more reliable.

[0057] Example 5 Understandably, the entire upper assembly assembly (including bracket 4, connecting arm 401, and tilting frame 2) in Embodiment 5 needs to be supported and lifted by a lifting device. Simultaneously, to meet the requirements of mobile vehicle operations, the entire assembly unit needs to be integrated onto a mobile platform with continuous automatic feeding capabilities. If manual handling and reloading are required for each panel installed, automation efficiency will be significantly reduced.

[0058] To address the issues of onboard integration and continuous automatic feeding of the aforementioned devices, such as... Figure 1 and Figure 2 As shown, this embodiment provides a system integration solution. The entire device also includes a vehicle-mounted platform 5, with the base 1 slidably connected to the vehicle-mounted platform 5, allowing the entire assembly device to move along the vehicle body direction. The vehicle-mounted platform 5 is provided with at least one sound insulation panel storage rack 501 for storing stacked sound insulation panels 6 to be installed.

[0059] The sound insulation panel storage rack 501 is internally connected to a lifting device 502 (such as a scissor lift), and the top is connected to a pushing assembly 503. The pushing assembly 503 can be a cylinder, and the telescopic end of the cylinder is connected to a push plate, which is approximately the same size as the end face of the sound insulation panel 6.

[0060] The sound insulation panels 6 are stacked on the lifting device 502 in sequence. The lifting device 502 lifts the top layer of sound insulation panels 6 to the top of the storage rack in sequence.
