Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to a steel structure construction operation platform for highway toll stations. Background Technology

[0002] The high-speed toll station steel structure construction operation platform is a reusable work platform specifically designed for the installation, welding, painting, and maintenance of steel structures in high-speed toll stations (including toll booths, toll island steel structure frames, canopy support components, etc.). It uses a steel structure as its core load-bearing frame, combined with protective facilities, a work panel, and auxiliary systems (such as lifting and fixing devices). This specialized equipment provides a safe and stable working space for construction personnel in high-altitude or complex working environments, while also meeting the construction needs for positioning, splicing, and connecting (welding / bolt tightening) steel structure components.

[0003] Regarding the aforementioned technologies, it is believed that when constructing steel structures for highway toll stations, it is necessary to splice and weld various steel structures, apply various anti-rust coatings, etc. Especially when working at a certain height, it is necessary to use a reusable work platform to lift the work to a suitable height for high-altitude operations, providing an important safe and stable working space for construction workers.

[0004] However, due to the large overall mass of the steel structure after assembly, the working position is usually adjusted by moving the work platform. The ground at the steel structure construction site is not completely flat. After the working position of the mobile work platform is adjusted, the area may be uneven. As a result, when the mobile work platform moves to this position, it may not be able to maintain stability. For example, the support wheels may sway, posing a significant safety risk. This makes it difficult to keep the operating platform stable and makes it impossible to adjust the stability and environmental adaptability of the mobile work platform according to the actual site conditions. Summary of the Invention

[0005] The purpose of this invention is to provide a construction operation platform for steel structures of highway toll stations, which solves the problems mentioned in the background art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A steel structure construction operation platform for a highway toll station includes a mobile vehicle. The mobile vehicle is equipped with a level sensor for monitoring levelness and a support assembly for automatic leveling and adaptation to the construction site environment. A lifting assembly with adjustable construction height is installed on the top wall of the mobile vehicle. An offset mechanism capable of linear short-distance fine-tuning is installed on the top wall of the lifting assembly. An operating platform and a safety railing are installed on the top of the offset mechanism.

[0008] Furthermore, the support assembly includes a lateral movement mechanism, a primary adjustment mechanism, and a secondary adjustment mechanism. The lateral movement mechanism includes a drive motor fixedly installed on the side wall of the mobile carrier. An installation groove is provided in the inner top wall of the mobile carrier. A high-strength bidirectional lead screw is rotatably installed on the inner wall of the installation groove. The power shaft of the drive motor passes through the mobile carrier and is fixedly connected to the bidirectional lead screw via a coupling. Slides that slide on the inner wall of the installation groove are screwed to both sides of the outer wall of the bidirectional lead screw. A moving platform is fixedly installed on the bottom wall of each slide. Limit seats are fixedly installed on the front and rear walls of each moving platform. Limit grooves are provided in the front and rear walls of the mobile carrier. Limit rods are provided on the inner walls of each limit groove. The outer walls of the limit rods are slidably connected to the inner walls of the corresponding limit seats.

[0009] Furthermore, the primary adjustment mechanism includes a mounting plate fixedly installed on the outer wall of the moving platform. Several diagonal braces to increase support stability are installed at an angle on the mounting plate and the outer wall of the moving platform. A primary adjustment push rod is fixedly installed on the top wall of the mounting plate. The movable end of the primary adjustment push rod slides through the mounting plate and a lifting platform is fixedly installed thereon.

[0010] Furthermore, the secondary adjustment mechanism includes a fine-tuning push rod fixedly installed at the front and rear of the top wall of the lifting platform. The movable end of the fine-tuning push rod slides through the lifting platform and is fixedly installed on a support platform. Several abutment platforms are installed at intervals on the bottom wall of the support platform.

[0011] Furthermore, the lifting assembly includes a mounting platform fixedly installed at the bottom of the offset mechanism, positioning frames are fixedly installed at the front and rear of the mobile carrier and the mounting platform, and telescopic positioning pins are fixedly installed at the four corners of the mobile carrier and the mounting platform.

[0012] Furthermore, each of the outer walls of the positioning frame has a positioning groove on the right side, and a positioning rod is fixedly installed on the inner wall of each positioning groove. Each positioning rod has a positioning block that slides in the inner wall of the positioning groove. The positioning block at the bottom and the outer wall of the positioning frame are hinged to a primary lifting frame, and the positioning block at the top and the outer wall of the positioning frame are hinged to a secondary lifting frame. The primary lifting frame and the secondary lifting frame are rotatably connected by a connecting shaft.

[0013] Furthermore, the same fixed platform is fixedly installed between the positioning frames at the bottom, and the same control seat is provided between the secondary lifting frames. Hydraulic push rods are hinged to the front and rear parts of the top wall of the fixed platform, and the movable end of the hydraulic push rod is hinged to the outer wall of the control seat.

[0014] Furthermore, the offset mechanism includes a base fixedly installed at the bottom of the mounting platform. A track groove is provided in the middle of the top wall of the base. A high-power electric slide rail is installed on the inner wall of the track groove. A matching electric slider is provided on the outer wall of the electric slide rail. The top wall of the electric slider is fixedly connected to the bottom wall of the operating platform.

[0015] Furthermore, the distance between the electric slider and the electric slide rail is half the overall length of the base, thereby controlling the operating platform to extend half a distance to the left or right along the outer wall of the base, expanding the operating platform's working area and extension length at height and preventing the center of gravity from shifting.

[0016] Furthermore, the base has embedded grooves on both the front and rear sides of its top wall, and optical axes are provided on the inner walls of the embedded grooves. A fixing block that is fixedly connected to the bottom wall of the operating table is slidably installed on the outer wall of the optical axis.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This steel structure construction operation platform for highway toll stations is highly adaptable to various terrains, overcoming the limitations of complex construction environments. Through a multi-level horizontal adjustment mechanism of "lateral movement control + first-level coarse adjustment + second-level fine adjustment," combined with real-time monitoring by horizontal sensors and manual observation, the equipment can quickly adapt to diverse and complex terrains such as gravel ground, slopes, and potholes in the highway toll station construction area. Even when facing rugged ground with significant elevation differences, it can ensure that the mobile vehicle always maintains a stable posture by cyclically adjusting the support landing point. This completely solves the problem of traditional equipment being unable to operate or having limited operation due to uneven ground, greatly expanding the applicable scenarios of the equipment.

[0019] 2. The steel structure construction operation platform of this highway toll station combines automatic leveling with manual observation, which makes the vehicle stable and quick to adjust without moving the whole equipment. The operation platform is driven by electric slider to switch work points in a short distance, eliminating the tedious process of readjusting and raising. The efficiency of work point switching is improved. The multi-stage lifting frame can accurately raise the operation platform to the target height, reducing the time spent on height adjustment. This allows construction personnel to quickly focus on core tasks and significantly reduces the time cost of non-operational links.

[0020] 3. The steel structure construction operation platform of this highway toll station forms a complete safety guarantee from foundation stability to personnel protection. Horizontal adjustment prevents the vehicle from swaying. The design of the safety fence and protective equipment mounting, and the dual positioning (positioning block + telescopic positioning pin) during the lifting process enhance the structural stability. When switching short distances, the movement range of the operating platform is strictly controlled (not exceeding 1 / 2 of the overall length) to ensure that the center of gravity always falls within the support area, effectively avoiding high-risk risks such as equipment tipping and personnel falling, and meeting the safety specifications for high-risk operations such as high-altitude welding and painting.

[0021] 4. The steel structure construction operation platform of this highway toll station features a stable vehicle posture, which avoids weld deviation caused by equipment shaking during welding and uneven coating caused by platform bumps during painting. The double limiting structure (positioning block + positioning groove, fixing block + optical axis) during lifting ensures that the platform does not wobble or deviate. The path is precise and controllable during short-distance movement, allowing construction personnel to accurately align with the work points, improving the fit of the steel structure installation, the welding qualification rate, and the uniformity of the coating, thus ensuring the delivery of the steel structure construction of the highway toll station.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Please see Figures 1-10 This invention provides a steel structure construction operation platform for a highway toll station, including a mobile vehicle 1. The mobile vehicle 1 is equipped with a level sensor for monitoring levelness. The mobile vehicle 1 is also equipped with a support component 2 for automatic leveling and adaptation to the construction site environment. The top wall of the mobile vehicle 1 is equipped with a lifting component 3 that can be raised and lowered to control and adjust the construction height. The top wall of the lifting component 3 is equipped with an offset mechanism 4 that can be linearly adjusted by short distances. The top wall of the offset mechanism 4 is equipped with an operating platform 5 and a safety fence 6 installed on the top of the operating platform 5.

[0040] In this implementation plan, each component adopts a modular integrated design. The mobile vehicle 1 serves as the core load-bearing foundation and is made of high-strength alloy steel in one piece, which ensures the rigidity of the overall structure while reducing its own weight for easy and flexible movement. The horizontal sensor adopts a high-precision tilt sensor, which can capture the changes in the vehicle's attitude in real time and provide accurate data support for subsequent leveling operations. All components work together to achieve an integrated operation process of "leveling-lifting-translation", which completely solves the pain points of traditional construction platforms such as poor terrain adaptability and limited operating range.

[0041] Specifically, the support component 2 includes a lateral movement mechanism, a primary adjustment mechanism, and a secondary adjustment mechanism. The lateral movement mechanism includes a drive motor 24 fixedly installed on the side wall of the mobile carrier 1. The inner top wall of the mobile carrier 1 has an installation groove 21. A high-strength bidirectional lead screw 23 is rotatably installed on the inner wall of the installation groove 21. The power shaft of the drive motor 24 passes through the mobile carrier 1 and is fixedly connected to the bidirectional lead screw 23 via a coupling. Slides 25 that slide on the inner wall of the installation groove 21 are screwed to both sides of the outer wall of the bidirectional lead screw 23. A moving platform 28 is fixedly installed on the bottom wall of the slide platform 25. Limit seats 27 are fixedly installed on the front and rear walls of the moving platform 28. Limit grooves 22 are opened on the front and rear walls of the mobile carrier 1. Limit rods 26 are provided on the inner walls of the limit grooves 22. The outer walls of the limit rods 26 are slidably connected to the inner walls of the corresponding limit seats 27.

[0042] In this implementation scheme, the bidirectional lead screw 23 is made of alloy material to ensure the smoothness and synchronization of the slide table 25 movement. The drive motor 24 is a servo motor equipped with a planetary reducer, which has a large output torque and high control precision, and can realize precise control of the extension distance of the moving table 28. The limit seat 27 and the limit rod 26 adopt a clearance fit design to ensure smooth sliding and to offset the radial force of the bidirectional lead screw 23 through a double guide structure, preventing the moving table 28 from deflecting or shaking when it extends. The maximum extension distance can be designed according to construction requirements, effectively widening the support span and providing more landing point options for leveling complex terrain.

[0043] Specifically, the primary adjustment mechanism includes a mounting plate 29 fixedly installed on the outer wall of the moving platform 28. Several diagonal braces to increase support stability are installed at an angle on the mounting plate 29 and the outer wall of the moving platform 28. A primary adjustment push rod 210 is fixedly installed on the top wall of the mounting plate 29. The movable end of the primary adjustment push rod 210 slides through the mounting plate 29 and a lifting platform 211 is fixedly installed thereon.

[0044] In this implementation scheme, the diagonal brace adopts a triangular stable structure design and is fixed to the mounting plate 29 and the moving platform 28 by welding. This can disperse the lateral force generated when the first-level adjustment push rod 210 is working, and avoid the long-term deformation of the mounting plate 29 under load. The first-level adjustment push rod 210 is an electric hydraulic push rod with a lifting stroke of up to 300mm, which can quickly offset the height difference of 10-20cm on the ground and realize the coarse adjustment of the vehicle's attitude.

[0045] Specifically, the secondary adjustment mechanism includes a fine-tuning push rod 212 fixedly installed on the front and rear of the top wall of the lifting platform 211. The movable end of the fine-tuning push rod 212 slides through the lifting platform 211 and is fixedly installed on a support platform 213. Several abutment platforms 214 are installed at intervals on the bottom wall of the support platform 213.

[0046] In this implementation scheme, the fine-tuning push rod 212 adopts a servo electric push rod, which can achieve millimeter-level height compensation to accurately offset small differences in ground elevation. It forms a closed-loop control with the level sensor to ensure that the vehicle's levelness error is small. The support platform 213 adopts an integral steel structure with 3-4 evenly distributed abutment platforms 214 at the bottom. The bottom of the abutment platforms 214 is equipped with anti-slip rubber pads, which not only increases the contact area with the ground and reduces the pressure per unit area to avoid sinking into soft ground, but also improves the stability of the support and prevents sliding and deviation.

[0047] Specifically, the lifting assembly 3 includes a mounting platform 31 fixedly installed at the bottom of the offset mechanism 4, positioning frames 33 fixedly installed at the front and rear of the mobile carrier 1 and the mounting platform 31, and telescopic positioning pins 32 fixedly installed at the four corners of the mobile carrier 1 and the mounting platform 31.

[0048] In this implementation plan, the mounting platform 31 is equipped with internal reinforcing ribs that have excellent bending and torsional strength, which can evenly distribute the load-bearing pressure of the operating platform 5. The telescopic positioning pin 32 adopts a multi-section telescopic rigid structure, which automatically locks as the mounting platform 31 rises and falls synchronously, forming multi-node support, improving wind load resistance and preventing swaying caused by airflow disturbance during the lifting process. The positioning frame 33, the mobile carrier 1, and the mounting platform 31 are all symmetrically arranged front and back to ensure balanced lifting force and avoid unilateral tilting.

[0049] Specifically, each of the right sides of the outer wall of the positioning frame 33 has a positioning groove 34, and each of the inner walls of the positioning groove 34 has a positioning rod 35 fixedly installed. Each of the outer walls of the positioning rod 35 has a positioning block 36 that slides in the inner wall of the positioning groove 34. The positioning block 36 at the bottom and the outer wall of the positioning frame 33 are hinged to a first-stage lifting frame 37, and the positioning block 36 at the top and the outer wall of the positioning frame 33 are hinged to a second-stage lifting frame 38. The first-stage lifting frame 37 and the second-stage lifting frame 38 are rotatably connected by a connecting shaft 312.

[0050] In this implementation scheme, the positioning block 36, positioning groove 34, and positioning rod 35 form a double guiding constraint, which strictly limits the movement trajectory of the primary lifting frame 37 and the secondary lifting frame 38, and prevents left and right swaying or twisting during the lifting process. The primary lifting frame 37 and the secondary lifting frame 38 adopt a scissor-type structure design, which is suitable for the steel structure operation requirements of different heights in highway toll stations. The connecting shaft 312 adopts a needle roller bearing design to ensure that the lifting frame rotates flexibly, the power transmission loss is small, and the lifting process is smooth and without jerking.

[0051] Specifically, the same fixed platform 39 is fixedly installed between the positioning frames 33 at the bottom, and the same control seat 310 is set between the secondary lifting frames 38. Hydraulic push rods 311 are hinged to the front and rear parts of the top wall of the fixed platform 39, and the movable end of the hydraulic push rod 311 is hinged to the outer wall of the control seat 310.

[0052] In this embodiment, the fixed platform 39 and the positioning frame 33 form a stable support base, ensuring that the hydraulic push rod 311 is firmly installed and does not shift during operation; the hydraulic push rod 311 drives the secondary lifting frame 38 to rise and fall smoothly to avoid tilting of the mounting platform 31, and can adapt to the angle changes during the movement of the lifting frame, ensuring smooth power transmission and improving the continuity and reliability of the lifting action.

[0053] Specifically, the offset mechanism 4 includes a base 41 fixedly installed at the bottom of the mounting platform 31. A track groove 43 is provided in the middle of the top wall of the base 41. A high-power electric slide rail 47 is installed on the inner wall of the track groove 43. A matching electric slider 46 is provided on the outer wall of the electric slide rail 47. The top wall of the electric slider 46 is fixedly connected to the bottom wall of the operating platform 5.

[0054] In this implementation scheme, the track groove 43 adopts a closed design with an internal dustproof sealing gasket to prevent dust, gravel and other debris from entering, protecting the electric slide rail 47 and the electric slider 46 and extending their service life; the electric slide rail 47 uses a linear module equipped with a high-precision ball screw, and the high-horsepower drive motor 24 can realize the operation panel 5 to start and stop quickly and respond rapidly, meeting the needs of rapid switching between short-distance operation points.

[0055] Specifically, the electric slider 46 slides along the electric slide rail 47 at a distance equal to half the overall length of the base 41, thereby controlling the operating platform 5 to extend half a distance to the left or right along the outer wall of the base 41, expanding the operating platform 5's working area and extension length at height and preventing the center of gravity from shifting.

[0056] In this implementation scheme, the spacing design is based on the center of gravity balance analysis. By limiting the maximum extension distance of the operating platform 5 to 1 / 2 of the length of the base 41, it is ensured that even when working at the edge of the operating platform 5, the overall center of gravity still falls within the support range of the base 41 and the mobile carrier 1. This design maximizes construction safety without sacrificing operational flexibility, avoids the risk of equipment tipping over due to center of gravity shift, and effectively expands the work coverage area, reduces the number of times the overall equipment is moved, and improves work efficiency.

[0057] Specifically, the base 41 has an embedded groove 42 on the front and rear of the top wall, and an optical axis 44 is provided on the inner wall of the embedded groove 42. A fixing block 45 that is fixedly connected to the bottom wall of the operating table 5 is slidably installed on the outer wall of the optical axis 44.

[0058] In this embodiment, the fixing block 45 and the optical axis 44 are fitted with a clearance, forming a double guide structure with the electric slide rail 47, which completely prevents the operation table 5 from deflecting, jamming or shifting when it moves, and ensures that the movement path is accurate and controllable; at the same time, the fixing block 45 is rigidly connected to the bottom wall of the operation table 5, which can distribute the load-bearing pressure of the operation table 5, enhance the overall structural stability, and ensure that it is not easily deformed during long-term use.

[0059] Working principle of this device: The power and control system of this device is modularly designed. The drive motor 24, the first-stage adjustment push rod 210, the fine-tuning push rod 212, the hydraulic push rod 311, the electric slider 46 and the electric slide rail 47 are stably connected to the external power supply. All of the above-mentioned actuators are electrically interconnected with the external controller. Their signal input terminals are connected to the controller's signal output terminals to form a closed-loop control link of "command issuance - action execution". The high-precision level sensor built into the mobile carrier 1 has its signal feedback terminal connected to the controller in real time, providing data support for equipment leveling and ensuring the accuracy and timeliness of attitude control.

[0060] Lateral movement control: Start the drive motor 24 to drive the bidirectional lead screw 23 to rotate smoothly in the mounting slot 21 inside the mobile carrier 1. Through the lead screw transmission principle, drive the slide 25 screwed to it to move away synchronously in the opposite direction along the outer wall of the bidirectional lead screw 23. The slide 25 is rigidly connected to the moving platform 28, driving the moving platform 28 to gradually extend outward from inside the mobile carrier 1.

[0061] During the extension process, the moving platform 28 drives the limiting seat 27 to slide synchronously along the outer wall of the limiting rod 26 and the inner wall of the limiting groove 22. The double limiting structure not only strictly limits the outward movement path of the moving platform 28, but also improves the support rigidity by dispersing the force, avoiding deformation or shaking during the extension process. The synchronously extended mounting plate 29, the first-level adjustment mechanism and the second-level adjustment mechanism, together with manual visual observation and horizontal sensor data reference, can be quickly positioned to a relatively flat support area, laying the foundation for subsequent leveling operations.

[0062] Level adjustment: Activate the first-level adjustment push rod 210, whose telescopic end pushes the lifting platform 211 to drive the second-level adjustment mechanism to descend vertically, precisely driving the support platform 213 and the contact platform 214 to contact the ground. If the contact platform 214 forms a surface contact with the ground and establishes a stable support, the mobile carrier 1 immediately presents a horizontal posture. At this time, the built-in level sensor continuously monitors the overall stability, and the data is fed back to the controller in real time, forming a dynamic monitoring closed loop to ensure that the support status is stable and without fluctuations. This level of adjustment can quickly offset slight undulations in the ground and is suitable for construction sites with small slopes and gentle undulations, greatly shortening the initial leveling time.

[0063] Secondary leveling adjustment: If the abutment platform 214 still cannot form effective support with the ground after the primary adjustment push rod 210 is driven (such as in complex situations such as deep pits or protrusions on the ground), the controller immediately triggers the fine-tuning push rod 212 to compensate for the non-contact gap through its precise extension and retraction, pushing the support platform 213 and the abutment platform 214 to achieve fine-tuning until a stable support is formed in close contact with the ground. The introduction of secondary adjustment enables the equipment to have multi-level adaptation capabilities of "coarse adjustment + fine adjustment", and can quickly level even when facing complex ground with large height differences.

[0064] Cyclic control mechanism: If the level sensor still detects that the mobile vehicle 1 has not reached the stable standard after the first and second level adjustments, the system will automatically repeat the lateral movement control process, driving the mobile platform 28, the mounting plate 29 and the adjustment mechanism to extend further outward. After reselecting the support landing point, the two-level level adjustment will be restarted. The coordinated cooperation of manual observation and automatic monitoring not only shortens the leveling time, but also enables the equipment to cope with the diverse and complex environment commonly found in highway toll station construction areas, such as gravel ground, slopes, and potholes, through a multi-level control mechanism. Precise level control not only keeps the mobile vehicle 1 in a stable posture, but also eliminates slight shaking during the construction process, laying a solid safety foundation for high-altitude operations, welding operations and other high-risk operations, and avoiding safety hazards such as equipment tilting and personnel falling due to uneven ground.

[0065] Work preparation and safety protection: After the mobile vehicle 1 has been stabilized and leveled, before the construction personnel climb onto the operating platform 5, they must securely attach safety hooks, safety belts and other protective equipment to the safety fence 6. The safety fence 6 is made of high-strength alloy material, and the height and spacing of the fence meet the safety standards for high-altitude operations. Its protection range fully covers the edge of the operating platform 5. Combined with the double protection of the protective equipment, a safety guarantee system without blind spots is formed to avoid the risk of personnel falling from the source.

[0066] Lifting control: The hydraulic push rod 311 on the fixed platform 39 is activated, and its powerful telescopic end pushes the control seat 310 and the secondary lifting frame 38 to rise vertically. The secondary lifting frame 38 is connected to the primary lifting frame 37 through the connecting shaft 312, and synchronously drives the primary lifting frame 37 to rise together. During the lifting process, the primary lifting frame 37 and the secondary lifting frame 38 drive the positioning block 36 to slide synchronously along the outer wall of the positioning rod 35 and the inner wall of the positioning groove 34. The dual positioning structure strictly limits the lifting path to ensure that there is no swaying or bumping during the lifting process, and the lifting posture is always stable.

[0067] Telescopic positioning pin 32 assistance: When the secondary lifting frame 38 is raised, the telescopic positioning pin 32 is stretched synchronously. Its insertion positioning design can not only accurately limit the lifting route, but also distribute the load-bearing pressure of the lifting frame through rigid support, and improve the overall structure's resistance to wind load and vibration. The installation platform 31, base 41 and operating platform 5 are accurately raised to the working point height. Construction personnel can carry out installation, welding, painting and maintenance of the steel structure of the highway toll station on the stable operating platform 5, which can adapt to the working needs of different heights.

[0068] Short-distance work point switching: When a short-distance work point switching is required, the construction personnel need to squat down to lower their center of gravity and firmly hold onto the safety railing 6. The electric slide rail 47 is activated to drive the electric slider 46 to slide smoothly along the outer wall of the track groove 43. The electric slider 46 is rigidly connected to the operating table 5, which drives the operating table 5 to achieve short-distance left and right adjustment. During the adjustment process, the operating table 5 drives the fixed block 45 to slide along the outer wall of the optical axis 44 and the inner wall of the embedded groove 42. The double limit structure effectively prevents the operating table 5 from deflecting or shifting, ensuring that the movement path is accurate and controllable.

[0069] The short-distance adjustment stroke of the control panel 5 is strictly limited to 1 / 2 of its overall length. The core of this design is to ensure that the overall working center of gravity of the control panel 5 and the safety fence 6 always falls within the support range of the base 41 and the mobile carrier 1, thereby increasing the equipment's anti-tipping coefficient. This not only avoids the risk of equipment tipping due to center of gravity shift, but also allows construction personnel to quickly switch work points without leaving the machine, improving work efficiency. At the same time, it eliminates the cumbersome process of moving and re-leveling the entire equipment, achieving a dual unity of "efficient operation" and "safety assurance".

[0070] This equipment, through its integrated design of "multi-level leveling + precise lifting + flexible translation", not only solves the core pain points in the construction of steel structures for highway toll stations, such as adapting to complex terrain, stabilizing high-altitude operations, and quickly switching work points, but also reduces construction safety risks through multiple safety protection structures (such as safety fence 6, telescopic positioning pin 32, and center of gravity control design) and a precise control system.

[0071] In welding operations, a stable carrier posture can prevent weld deviation and improve welding quality; in painting operations, a shaky operating table 5 ensures uniform coating and reduces material waste; in maintenance operations, precise lifting and translation functions allow construction personnel to quickly locate maintenance points and shorten the operation cycle.

[0072] It fully embodies the design effect of "strong adaptability, high safety, outstanding efficiency and excellent precision", and provides reliable equipment support for the construction of steel structure of highway toll stations.

Although the present invention 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.
