Description

Technical Field

[0001] This invention relates to the field of railway construction platform technology, specifically a construction platform based on a high-rise steel structure. Background Technology

[0002] Railway steel structure construction platforms are high-altitude operation support systems specifically designed for railway engineering construction. They are mainly composed of welded or bolted steel sections (H-beams, I-beams, etc.) and are used to provide a safe and stable construction working surface.

[0003] Publication No. CN223104090U discloses an easily disassembled steel structure construction platform, characterized by comprising several rows of interconnected first and second frames that enclose a cable tower. The first and second frames are bolted to the cable tower. Each first frame includes a first support plate with several first connecting bolt holes and a first walkway located at the upper end of the first support plate. Each second frame includes a second support plate with several second connecting bolt holes and a second walkway located at the upper end of the second support plate. The upper portions of the first and second walkways are respectively equipped with first and second guardrails. The first walkway also has a climbing board, through which a vertically arranged ladder is connected. The ladder is vertically connected to other first frames adjacent in the height direction, facilitating construction at different heights of the cable tower. This device reduces adverse effects on the cable tower, makes installation and disassembly of the construction platform convenient, improves the construction efficiency of the cable tower, and offers high safety and economic practicality.

[0004] However, in actual use, when this device and existing equipment are used for railway construction, it is usually necessary to pour concrete at the railway construction site. During the pouring process, due to the changes in the weight of the concrete and the changes in the pouring point, the load (personnel, tools, materials) will not be evenly distributed on both sides of the platform. The load is concentrated on one side or edge of the platform, causing the center of gravity of the platform to shift, generating additional overturning moment, which causes the angle of the construction platform to change and tilt. This situation obviously poses a great safety hazard.

[0005] Existing equipment typically provides some protection for construction workers when imbalanced. However, when the overturning moment exceeds the platform's anti-overturning capacity, the entire platform may tip over. Existing equipment cannot promptly address the tilt angle of the construction platform in such situations. Simply adjusting the load to maintain a balanced load on the construction platform is obviously cumbersome and significantly reduces railway construction efficiency. There is room for further improvement in the adjustment effectiveness of existing equipment for construction platforms during railway construction. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] Please see Figures 1 to 8A construction platform based on a high-rise steel structure includes a mobile chassis 1 for supporting the platform. A scissor lift structure 10 is fixedly connected to the top of the mobile chassis 1. A balance plate 2 is fixedly connected to the top of the scissor lift structure 10. Two balance chambers 20 are provided on both sides of the balance plate 2, but not at the same horizontal height. Two piston plates 21 are provided and movably connected inside the two balance chambers 20 respectively. Four reset structures 22 are provided, respectively located inside the two balance chambers 20 and at their rear sides. A top column 23 is fixedly connected to the top of one piston plate 21 and the bottom of the other piston plate 21. The top column 23 penetrates the balance chamber 20 and extends to the outside of the balance chamber 20. The top extension of the top column 23 and the bottom extension of the top column 23 on the other side are both fixedly connected to the fixing plate 230. The top of the balance plate 2 is provided with a construction chamber 3. There are two first rotating parts 30, which are symmetrically fixedly connected to the bottom two sides of the construction chamber 3. There are two connecting parts 31, which are symmetrically rotatably connected to the inside of the first rotating part 30 and extend to the outside of the first rotating part 30. The top of the fixing plate 230 on one side is fixedly connected to the bottom of the connecting part 31 on one side, and the bottom of the connecting part 31 on the other side is fixedly connected to the top of the balance chamber 20 on the other side. The fixing plate 230 on the other side is fixedly connected to the top of the balance plate 2. The delivery pipe 24 is fixedly connected between the two balance chambers 20, and the connection between the delivery pipe 24 and the balance chamber 20 is fixedly connected to the hydraulic control check valve 240. The balance chamber 20 is filled with buffer solution.

[0033] In real-world railway construction, existing equipment typically requires concrete pouring at the construction site. During pouring, variations in concrete weight and pouring points cause the load (personnel, tools, materials) to become unevenly distributed across the platform. The load concentrates on one side or edge, shifting the platform's center of gravity and generating additional overturning moments. This results in a change in the platform's angle, causing it to tilt. Existing equipment cannot promptly address this tilt. Simply adjusting the load to maintain balance is cumbersome and significantly reduces railway construction efficiency.

[0034] This invention discloses a construction platform based on a high-rise steel structure. During railway construction, workers can stand inside the construction chamber 3 and close the door. Operators located on the mobile chassis 1 can activate the scissor lift structure 10 via the control center. The scissor lift structure 10 moves the balance plate 2 and the construction chamber 3 upwards until the construction chamber 3 reaches the railway construction area. At this point, workers can proceed with railway construction. The top sides of the two balance chambers 20 are respectively loaded with buffer fluid. When the construction platform tilts due to load changes inside the construction chamber 3, for example... Figure 4 When the right side of the construction platform tilts, the construction platform applies a downward force to the connecting member 31 at that location through the first rotating member 30 on the right side, causing the connecting member 31 to move downward. The downward movement of the connecting member 31 drives the right balance chamber 20 to move downward. Since the right fixed plate 230 is fixedly connected to the top of the balance plate 2, the right fixed plate 230 will not move during the downward movement of the right balance chamber 20. That is, the right top column 23 and the right piston plate 21 will not move. Thus, the right piston plate 21 maintains its original height during the downward movement of the right balance chamber 20. At this time, the capacity of the buffer solution in the right balance chamber 20 decreases, which increases the air pressure inside the right balance chamber 20 and transports a portion of the buffer solution to the left balance chamber 20 through the delivery pipe 24. The right hydraulic check valve 240 is used to prevent the buffer solution from flowing back into the right balance chamber 20.

[0035] After the buffer solution is obtained in the left-side balance chamber 20, the internal air pressure increases. Since the left-side balance chamber 20 is fixedly connected to the balance plate 2, it cannot move. This means that the left-side piston plate 21, left-side top column 23, and left-side fixed plate 230 can all move up and down. At this time, the increased air pressure inside the left-side balance chamber 20 causes the left-side piston plate 21 to move downwards. This downward movement of the left-side piston plate 21 causes the elastic element 220 to undergo elastic deformation, which in turn causes the left-side fixed plate 230 to move downwards via the left-side top column 23. The movement of the left-side fixed plate 230, through the left-side connecting member 31 and the left-side first rotating member 30, causes the left side of the construction platform to move downwards. The two first rotating members 30 and the two connecting members 31 simultaneously limit the movement of the construction platform. When the air pressure inside the two balance chambers 20 is the same, the construction platform remains horizontal, thus completing the automatic correction of the construction platform when the load changes or the platform tilts. Figure 4As shown, after the construction chamber 3 rises, the weight inside it will not continue to increase. That is, a continuous force is applied to the right side of construction chamber 3, and this force will not increase further. The two balancing chambers 20 only need to balance once to maintain the construction chamber 3 at a horizontal height. As the weight of the heavy object (concrete, putty, etc.) decreases through spraying, the two balancing chambers 20 can continuously adjust the tilt of construction chamber 3 as the weight decreases, minimizing any safety hazards to construction workers caused by the tilt of construction chamber 3. Figure 4 When the left side of the construction platform tilts, the equipment can be adjusted in the same way. The only difference is that the liquid delivery direction is reversed when adjusting the two hydraulic control check valves 240. The device can automatically complete the adjustment of the construction platform without significantly reducing the efficiency of railway construction, which is convenient for users.

[0036] Please see Figures 4 to 8 Further described above, the reset structure 22 includes a blocking frame 223. The blocking frame 223 has two elastic elements 220 inside, with the elastic elements 220 near the balance chamber 20 respectively positioned between the piston plate 21 and the bottom inner wall of the balance chamber 20. Mounting plates 221 are fixedly connected to the top and bottom of each elastic element 220. A clamping plate 222 is fixedly connected to the top of each mounting plate 221. Two mounting plates 221 on one side of the top are slidably connected to the blocking frame 223 at that location, while two mounting plates 222 on the other side of the bottom are slidably connected to the other side of the bottom. The mounting plate 221 is slidably connected to the sealing frame 223 at that location. The two mounting plates 221 near the balance chamber 20 and located on the top side are respectively engaged with the piston plate 21 and the bottom inner wall of the balance chamber 20 through the two clamping plates 222 on the top side and the clamping grooves opened on the piston plate 21 and the bottom inner wall of the balance chamber 20. The rear end of the balance chamber 20 is not closed. A sealing plate is fixedly connected to the inner wall of the sealing frame 223. The inner walls on both sides of the sealing frame 223 near the balance chamber 20 are tightly fitted to the left and right surfaces of the balance chamber 20, respectively.

[0037] The sealing frame 223 can be used to seal the inside of the balance chamber 20, maintaining a sealed space within the balance chamber 20. The elastic element 220 is used to allow the equipment to automatically reset itself after the railway construction work is completed, assisting in readjusting the air pressure and buffer solution in the two balance chambers 20 to their initial state through the elastic deformation of the elastic element 220, thus completing the reset of the construction platform. The slot and block design is for subsequent replacement of the elastic element 220. Two mounting plates 221 on the top of one side are slidably connected to the sealing frame 223 at that location, and two mounting plates 221 on the bottom of the other side are slidably connected to the sealing frame 223 at that location for... Figure 4When the piston plate 21 on the left side moves and the balance chamber 20 on the right side moves, interference with their movement is avoided. At the same time, the movement of the elastic element 220 can be limited to a certain extent to avoid the elastic element 220 deflecting during elastic deformation or elastic deformation reset, which would make it difficult for it to complete the reset later.

[0038] Please see Figures 5 to 7 Furthermore, as described above, two switching components 25 are fixedly connected to the top rear side of the balance plate 2, and the two switching components 25 are respectively located at one end near the two balance chambers 20. The switching component 25 includes a first rotary drive component 250, which is specifically a drive motor. A rotating rod 251 is fixedly connected to the bottom output end of the first rotary drive component 250. A connecting plate 252 is fixedly connected to the bottom of the rotating rod 251. Grouping plates 253 are fixedly connected to the front and rear ends of the connecting plate 252. Two linear drive components 254 are fixedly connected to the end of the grouping plate 253 away from the connecting plate 252. The linear drive components 254 are configured as hydraulic cylinders. The output end of the linear drive components 254 away from the grouping plate 253 is fixedly connected to the reset structure 22.

[0039] During prolonged use of the construction platform, the elastic element 220 may experience elastic fatigue due to long-term elastic deformation, making it difficult to return to its elastic deformation state. After construction, the operator at the mobile chassis 1 can determine whether the elastic element 220 has experienced elastic fatigue and needs replacement by observing whether the construction platform is tilted after being reset. If the construction platform remains tilted after being reset, it indicates that the elastic element 220 has experienced elastic fatigue and is difficult to return to its elastic deformation state. In this case, the operator can activate the four linear drive components 25 at the front end through the control center. 4. The four linear drive components 254 are activated, causing the front-end reset structure 22 to disengage from the two balance chambers 20. The control center then activates the first rotary drive component 250, which in turn drives the rotating rod 251 to rotate. The rotating rod 251 rotates, which in turn drives the connecting plate 252 to rotate. The rotating plate 252 rotates, which in turn drives the four linear drive components 254 to rotate via the grouping plate 253, until the four elastic elements 220 that were originally located at the rear are now facing the two balance chambers 20 at the front. The four elastic elements 220 that were originally used are now located at the rear of the two balance chambers 20.

[0040] At this time, the linear drive assembly 254 is activated by the control center. The linear drive assembly 254 drives the reset structure 22 to move towards the balance chamber 20 until the two blocking frames 223 block the two balance chambers 20. The top and bottom plates 222 of the unused elastic element 220 are engaged with the bottom of the piston plate 21 and the groove on the bottom inner wall of the balance chamber 20. During this period, the operator can also replenish the buffer in the two balance chambers 20. After the above steps are completed, the equipment completes the replacement of the reset structure 22, avoiding the situation where the elastic element 220 cannot be elastically deformed and reset after long-term use, and the construction platform is difficult to reset, which is convenient for users.

[0041] Please see Figures 3 to 9 Furthermore, as described above, a fixing groove 310 is provided at the front end extension of the connector 31, and fixing chambers 4 are symmetrically fixedly connected to the bottom sides of the construction chamber 3. A second rotary drive assembly 40 is fixedly connected to the front inner wall of the fixing chamber 4. The second rotary drive assembly 40 is specifically a drive motor. A screw 41 is fixedly connected to the rear output end of the second rotary drive assembly 40. A push rod 42 is threadedly connected to the outer surface of the screw 41 and extends through and to the rear outer side of the fixing chamber 4. The push rod 42 is rectangular. A limit sleeve 420 is fixedly connected to one end of the push rod 42 near the second rotary drive assembly 40. A fixing block 421 with the same shape and size as the fixing groove 310 is fixedly connected to the extension of the push rod 42. The total mass of the four reset structures 22 is the same as the total mass of the two fixing chambers 4.

[0042] During the marking and electrical wiring processes in railway construction, small equipment is used, making it difficult to assess the load on the construction platform. However, vibrations from train travel in the railway construction environment can cause resonance, leading to platform resonance. While the platform won't tilt at a large angle, the vibrations repeatedly exert force on the connecting member 31 through the first rotating component 30, causing the platform to tilt after adjusting the buffer solution in the two balance chambers 20. This can result in accidental contact between the two balance chambers 20. At this point, the operator at the mobile chassis 1 can activate the two second rotary drive components 40 via the control center. The activation of the two second rotary drive components 40 drives the two screws 41 to rotate. The rotation of the screws 41 causes the push rod 42 to move backward, which in turn moves... The fixing block 421 moves toward the fixing groove 310 until it is engaged inside the fixing groove 310. The device uses a drive motor, screw 41, and push rod 42 to replace the common hydraulic cylinder and pneumatic cylinder. On the one hand, the drive motor responds faster, and on the other hand, the screw 41 and push rod 42 have a self-locking mechanism, making the connection between the fixing block 421 and the fixing groove 310 tighter. At the same time, unlike the large energy required to keep it fixed by the hydraulic cylinder, this connection method consumes less energy and is more suitable for railway construction. After the fixing block 421 is engaged in the fixing groove 310, the first rotating part 30 and the connecting part 31 can no longer rotate, and the two balance chambers 20 can no longer adjust the buffer fluid. That is, the two balance chambers 20 will not cause accidental contact, which is convenient for users.

[0043] The total mass of the four reset structures 22 is the same as the total mass of the two fixed chambers 4, and is used to adjust the overall mass of the balance plate 2-construction chamber 3 structure;

[0044] Please see Figures 1 to 4 Furthermore, as described above, a second rotating component 32 is fixedly connected to the bottom center of the construction chamber 3, and an opening and closing door is rotatably connected to the front end of the construction chamber 3.

[0045] The second rotating component 32 is used to connect an external ladder. When construction workers on the ground need to go up, they can climb the ladder into the construction room 3 without having to reset the scissor lift structure 10, which is convenient for users.

[0046] Please see Figures 1 to 2 Furthermore, in the above description, the mobile chassis 1 consists of a frame, a driving structure, a steering assembly, four tires, a power source, an emergency stop system, and a control center. The frame is fixedly connected to the driving structure, the steering assembly, and the four tires, and the power source is electrically connected to the driving structure, the emergency stop system, and the control center.

[0047] Please see Figures 1 to 2Furthermore, as described above, the control center consists of a central processing unit, a memory, input / output interfaces, expansion interfaces, a power supply, and a communication interface, and the central processing unit, memory, input / output interfaces, expansion interfaces, power supply, and communication interfaces are electrically connected to each other.

[0048] Please see Figures 1 to 2 Furthermore, in the above description, the scissor lift structure 10 consists of multiple scissor arm assemblies, a hydraulic drive system, a limiting structure, an upper hinge point, and a lower support base. The hydraulic drive system, the limiting structure, the upper hinge point, and the lower support base are fixedly connected to each other, and the multiple scissor arm assemblies are rotatably connected to each other.
