[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined Figure 1 Describe the structure and working principle of this utility model.

[0044] Reference Figure 1 The construction device provided by this utility model includes a moving component 100, a counterweight component 200, a first telescopic component 300, a second telescopic component 400, and a working chamber 500. The counterweight component 200 is disposed on one side inside the moving component 100; the first telescopic component 300 is disposed on the other side of the moving component 100 and is used for telescopic extension and retraction in a first direction; the second telescopic component 400 is disposed at the movable end of the first telescopic component 300 and is used for telescopic extension and retraction in a second direction; the working chamber 500 is disposed at the movable end of the second telescopic component 400, and the working chamber 500 moves under the action of the first telescopic component 300 and the second telescopic component 400.

[0045] This invention achieves overall relocation through a movable component 100, while a counterweight component 200 balances the cantilever load of the first telescopic component 300 and the second telescopic component 400, ensuring operational stability. The first direction is horizontal, and the second direction is vertical. Specifically, the first telescopic component 300 extends and retracts along the first direction to adjust the horizontal distance of the working chamber 500, and the second telescopic component 400 extends and retracts along the second direction to adjust the vertical height of the working chamber 500. Their combined action allows the working chamber 500 to be precisely positioned at the sound insulation panel installation location. The working chamber 500 provides an operating platform, allowing construction personnel to complete the installation of the sound insulation panel without the need for an additional bridge inspection vehicle. This structure reduces the number of equipment coordination steps, lowers construction costs, avoids safety hazards associated with moving multiple pieces of equipment and transferring personnel, and improves construction efficiency.

[0046] Specifically, the counterweight component 200 is located inside the movable component 100 on one side. Its connection to the movable component 100 can be achieved using bolt fastening or an embedded slot structure to ensure counterweight stability. The first telescopic component 300 is connected to the other side of the movable component 100 via a flange or hinge. The flange can be fixed with high-strength bolts, while the hinge allows the first telescopic component 300 to be adjusted within a certain angle range. The second telescopic component 400 is connected to the movable end of the first telescopic component 300 via a slide rail or sleeve structure. The slide rail can use a ball bearing guide to improve telescopic smoothness, while the sleeve structure achieves telescopic guidance through nested engagement. A rotating platform can be provided between the working chamber 500 and the movable end of the second telescopic component 400. The rotating platform achieves horizontal rotation via bearings or a slewing bearing, and the bottom plate of the working chamber 500 is fixed to the rotating platform by welding or bolting. The working chamber 500 can be equipped with a detachable material storage rack, which is fixed to the side wall of the working chamber 500 by hooks or pins for temporary storage of sound insulation panels or installation tools. In practical use, the work chamber 500 can be extended to the outside of the bridge 600 to enable operations to be performed on the outside of the bridge 600.

[0047] Reference Figure 1 In some embodiments of this utility model, the movable component 100 includes a base 110, a cover plate 120, a support frame 130, and a movable component 140. The counterweight component 200 of the base 110 is located at the top of the base 110; the cover plate 120 is spaced apart from the base 110; the support frame 130 is located between the base 110 and the cover plate 120; and the movable component 140 is located at the bottom of the base 110.

[0048] Specifically, the base 110 can be welded from steel plates, with a mounting surface at its top. The counterweight component 200 is fixed to this mounting surface with bolts to ensure the stability of the counterweight. The cover plate 120 is spaced apart from the base 110 and connected by a support frame 130. The support frame 130 can be welded or bolted to the upper surface of the base 110 and connected to the cover plate 120 via a flange or snap-fit ​​structure, forming a stable frame structure. The moving component 140 is located at the bottom of the base 110 and can be either wheeled or tracked. The wheeled moving component 140 is connected to the bottom of the base 110 via a bearing seat, which is fixed with bolts, allowing the moving component 140 to rotate freely. The tracked moving component 140 is connected to the bottom of the base 110 via a drive wheel and a tension wheel. The drive wheel is driven by a geared motor, and the tension wheel allows for track tension adjustment via an adjustable bracket.

[0049] The mobile component 100 is supported by a base 110, and a counterweight component 200 is located on top of the base 110 to balance the overturning moment during operation, enhancing the stability of the device. A rigid structure is formed between the cover plate 120 and the base 110 via a support frame 130, improving overall resistance to deformation. The mobile component 140 allows the device to move flexibly on the construction site; a wheeled structure is suitable for flat ground, while a tracked structure adapts to complex terrain. This structure reduces the need for coordinated operation of cranes and bridge inspection vehicles in traditional construction, lowers equipment costs, avoids safety hazards associated with multiple devices, and improves the efficiency and safety of soundproofing panel installation.

[0050] Reference Figure 1 In some embodiments of this utility model, the counterweight assembly 200 includes a counterweight chamber 210 and a counterweight body 230. The counterweight chamber 210 has a limiting cavity inside, with an opening on at least one side; the counterweight body 230 is disposed inside the limiting cavity to improve the stability of the moving assembly 100.

[0051] Specifically, the counterweight compartment 210 can be welded from steel plates, with its internal limiting cavity slightly larger than the counterweight body 230 to facilitate loading and unloading. The open side of the counterweight compartment 210 can be equipped with an openable and closable door, which is hinged to the side wall of the counterweight compartment 210 and secured by a pin or locking mechanism. The counterweight body 230 can be made of cast iron or concrete. Cast iron counterweight body 230 has higher density and corrosion resistance, while concrete counterweight body 230 has a lower cost advantage. An anti-slip rubber pad can be provided between the counterweight body 230 and the limiting cavity to prevent displacement of the counterweight body 230 during movement. Drainage holes can be provided at the bottom of the counterweight compartment 210 to prevent rainwater accumulation in the limiting cavity.

[0052] In this embodiment, the counterweight component 200 increases the overall weight of the moving component 100 through the counterweight body 230, effectively balancing the overturning moment generated by the first telescopic component 300 and the second telescopic component 400 during operation, thus improving the stability of the device. The limiting cavity of the counterweight chamber 210 can restrict the movement range of the counterweight body 230, preventing it from shaking or shifting during operation. The counterweight body 230 can be added, removed, or replaced according to actual working conditions to adapt to different operational needs. This structural design is simple and reliable, significantly improving the safety and stability of the construction device, while also facilitating the adjustment and maintenance of the counterweight.

[0053] In some possible embodiments, the counterweight chamber 210 may have multiple limiting cavities, each of which can hold an independent counterweight body 230, to achieve modular adjustment of the counterweight. The side walls of the counterweight chamber 210 may be reinforced with stiffeners to improve its structural strength. The surface of the counterweight body 230 may be provided with lifting rings for easy loading and unloading using lifting equipment. A sliding door may be provided on the open side of the counterweight chamber 210, which slides with the counterweight chamber 210 via guide rails and is fixed in position by limiting blocks when fully open. This design makes counterweight adjustment more flexible and convenient, while enhancing the structural reliability and ease of use of the counterweight chamber 210.

[0054] Reference Figure 1 In some embodiments of this utility model, the counterweight chamber 210 has an opening on one side, that is, the opening is located on the side of the counterweight chamber 210; the counterweight assembly 200 also includes a limiting plate 220, which is detachably provided at the opening and is used to close the opening.

[0055] Specifically, the openings of the limiting plate 220 and the counterweight chamber 210 are detachably connected. The limiting plate 220 can be bolted to the edge of the opening of the counterweight chamber 210. The edge of the opening of the counterweight chamber 210 has a flange with bolt holes. Corresponding through holes are provided on the limiting plate 220, and high-strength bolts with anti-loosening nuts are used for a secure connection. Alternatively, the limiting plate 220 can be installed using a sliding insertion method. Guide grooves are provided on both sides of the opening of the counterweight chamber 210, and matching flanges are provided on both sides of the limiting plate 220. Installation and positioning are achieved by sliding into the grooves, and locking is achieved with pins after positioning. The limiting plate 220 is made of Q235 steel plate, with the thickness determined according to the load-bearing requirements. The surface can be treated with rust prevention to improve durability. A sealing strip can be provided on the upper edge of the opening of the counterweight chamber 210 to achieve a seal and dust prevention when the limiting plate 220 is closed.

[0056] In this embodiment, the limiting plate 220 detachably closes the opening of the counterweight chamber 210, facilitating the loading and unloading of the counterweight body 230 while ensuring its stability during operation. When counterweight adjustment is needed, the limiting plate 220 can be removed to add, remove, or replace the counterweight body 230. During operation, the limiting plate 220 is securely installed to effectively prevent the counterweight body 230 from accidentally coming loose. The bolted connection provides high connection strength and is suitable for conditions with significant vibration; the sliding plug connection facilitates quick assembly and disassembly, making it suitable for situations requiring frequent adjustments. This structural design ensures both the convenience of counterweight adjustment and the safety and reliability during construction, while the sealing design extends the service life of the counterweight assembly 200.

[0057] In some possible embodiments, the limiting plate 220 may be provided with an observation window made of tempered glass or transparent polycarbonate sheet, facilitating a direct view of the status of the counterweight body 230. Multiple sets of connection holes may be provided on the edge of the opening of the counterweight chamber 210, allowing the limiting plate 220 to be adjusted vertically according to the loading height of the counterweight body 230. A buffer layer made of rubber or polyurethane material may be provided on the inner side of the limiting plate 220 to reduce the impact between the counterweight body 230 and the limiting plate 220. A drainage channel may be provided on the lower edge of the opening of the counterweight chamber 210 to drain any rainwater that may enter. This design enhances the functionality and adaptability of the counterweight assembly 200, making counterweight adjustment more convenient, while also improving protective performance and the level of visual management.

[0058] Reference Figure 1 In some embodiments of this utility model, the first telescopic component 300 includes a first driving member 310 and a first sliding member 320. The first driving member 310 is disposed on the moving component 100; the first sliding member 320 is slidably disposed on the first driving member 310, and extends and retracts horizontally under the drive of the first driving member 310. A first reinforcing member 330 is detachably disposed between the moving component 100 and the first driving member 310, the first reinforcing member 330 being used to improve the stability of the first driving member 310.

[0059] Specifically, the first driving component 310 is fixedly mounted on the base 110 of the moving assembly 100 via a flange connection. The base 110 has a positioning stop, and the mounting end of the first driving component 310 has a matching flange. The two are connected circumferentially by eight M12 high-strength bolts, with rubber gaskets added to the mating surfaces for shock absorption and anti-loosening. The first sliding component 320 is slidably mounted on the first driving component 310 via a linear guide pair. The guide rail is made of 45# steel with a surface hardening treatment and is fixed to the driving component housing by countersunk screws. The slider assembly is made of aluminum alloy and has an internal ball bearing circulation structure, connected to the first sliding component 320 by four M8 socket head cap screws. The piston rod end of the first driving component 310 is machined with external threads, which mate with the internal threaded hole of the first sliding component 320, and a double-nut anti-loosening measure is used. Stainless steel dust scrapers are provided on both sides of the guide rail to prevent construction dust from entering the slider. The first reinforcing member 330 can be connected to the support frame 130 and the first driving member 310 by bolts. Multiple installation positions can be set to facilitate adjustment of the angle of the first reinforcing member 330 according to the actual situation.

[0060] In this embodiment, the first driving component 310 drives the piston rod to extend and retract via hydraulic or electric means, causing the first sliding component 320 to move horizontally linearly along the guide rail. The precise fit of the linear guide rail pair ensures the smoothness and positioning accuracy of the extension and retraction movement, while the dustproof design extends its service life. The flange connection ensures that the driving component is firmly installed and can withstand vibration and impact loads during operation. This structure enables precise adjustment of the horizontal position of the working chamber 500, offering advantages such as smooth movement, accurate positioning, and high reliability compared to traditional crane operation methods. It also simplifies the equipment structure and reduces maintenance costs. The anti-loosening design effectively prevents connection loosening after long-term use, ensuring construction safety. The triangular support structure of the first reinforcing component 330 effectively disperses the force on the first driving component 310, reduces stress concentration at the root connection, and improves overall stability.

[0061] In some possible embodiments, the first sliding member 320 may be equipped with an auxiliary guide wheel assembly. These guide wheels, made of nylon, engage with guide grooves on the side of the drive member housing to share the load on the guide rail under heavy loads. The piston rod surface of the first drive member 310 may be hard chrome plated to improve wear resistance and corrosion resistance. Polyurethane buffer pads may be installed at both ends of the guide rail to reduce the impact when the sliding member reaches its limit position. The connection surface between the first sliding member 320 and the second telescopic assembly 400 may be machined into a serrated mating surface, and the connection rigidity is enhanced by bolt tightening. This design further improves the load-bearing capacity and operational stability of the first telescopic assembly 300, enabling it to adapt to more complex construction environments and heavier workloads.

[0062] Reference Figure 1 In some embodiments of this utility model, the second telescopic component 400 includes a second driving member 410 and a second sliding member 420. The second driving member 410 is disposed at the end of the first sliding member 320 away from the first driving member 310; the second sliding member 420 is slidably disposed at the end of the second driving member 410 away from the first sliding member 320, and the second sliding member 420 extends and retracts in the vertical direction under the drive of the second driving member 410. A second reinforcing member 430 is detachably provided between the second driving member 410 and the first sliding member 320, and the second reinforcing member 430 is used to provide stability for the second driving member 410. The second telescopic component 400 is similar in configuration to the first telescopic component 300, and the specific configuration can be referred to the configuration of the first telescopic component 300, which will not be repeated here.

[0063] Reference Figure 1 In some embodiments of this utility model, the movable component 140 is provided with a parking component, which is used to control the movement of the movable component 140. Specifically, the parking component can be a foot-operated brake. When parking is required, the brake is used to engage the movable component 140 to prevent it from moving.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
