Description

TECHNICAL FIELD

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

[0003] Publication No. CN223104090U discloses an easy-to-disassemble steel structure construction platform, characterized by: a plurality of rows of interconnected first and second frame bodies enclosing the cable tower, the first and second frame bodies are bolted to the cable tower, the first frame body includes a first support plate with a plurality of first connection screw holes bolted to the cable tower and a first walkway located at the upper end of the first support plate, the second frame body includes a second support plate with a plurality of second connection screw holes bolted to the cable tower and a second walkway located at the upper end of the second support plate, the first and second walkways are respectively provided with first and second guardrails, the first walkway is further provided with a climbing board, the climbing board is connected with a vertically arranged ladder, the ladder is vertically connected to the adjacent first frame body in the height direction, so as to facilitate construction at different heights of the cable tower, the device can reduce the adverse effects on the cable tower, the installation and disassembly of the construction platform are more convenient, the construction efficiency of the cable tower is improved, and the safety is high, economical and practical.

[0004] However, in actual use, the device and existing equipment usually need to pour concrete at the railway construction site during railway construction, and due to the weight change of the concrete and the change of the pouring site, the load (personnel, tools, materials) will not be evenly distributed on both sides of the platform, and the load will be concentrated on one side or edge of the platform, causing the center of gravity of the platform to shift and generate an additional overturning moment, thereby changing the angle of the construction platform and causing it to tilt. This situation obviously has great safety hazards.

[0005] The existing equipment usually takes certain protective measures for construction personnel when it is out of balance, but when the overturning moment exceeds the anti-overturning capacity of the platform, the entire platform may overturn, and the existing equipment cannot timely process the tilt angle of the construction platform in this case. The method of adjusting the load to keep the construction platform in balance is obviously more cumbersome and significantly reduces the efficiency of railway construction, and there is further room for improvement in the adjustment effect of the existing equipment on the construction platform during railway construction.

EMBODIMENT

[0022] Please refer to Figures 1 to 8The utility model provides a kind of construction platform based on high-rise steel structure, including the mobile chassis 1 for supporting the construction platform based on high-rise steel structure, the top of mobile chassis 1 is fixedly connected with scissor lift structure 10, the top of scissor lift structure 10 is fixedly connected with balance plate 2, balance chamber 20 is provided with two and is arranged at the both sides of balance plate 2, and two balance chambers 20 are not arranged at the same horizontal height, piston plate 21 is provided with two and is respectively movably connected in the inside of two balance chambers 20, reset structure 22 is provided with four, which are respectively arranged in the inside of two balance chambers 20 and at the rear side of two balance chambers 20, the top of one side piston plate 21 and the bottom of the other side piston plate 21 are fixedly connected with top column 23, top column 23 penetrates balance chamber 20 and extends to the outside of balance chamber 20, the top of one side top column 23 top extension and the bottom of the other side fixed column bottom extension are fixedly connected with fixed plate 230, the top of balance plate 2 is provided with construction chamber 3, first rotating part 30 is provided with two, which are symmetrically fixedly connected at the bottom of both sides of construction chamber 3, connecting piece 31 is provided with two, which are symmetrically rotatably connected in the inside of first rotating part 30 and extend to the outside of first rotating part 30, one side fixed plate 230 top is fixedly connected at the bottom of one side connecting piece 31, the bottom of the other side connecting piece 31 is fixedly connected at the top of the other side balance chamber 20, the other side fixed plate 230 is fixedly connected at the top of balance plate 2, delivery pipe 24 is fixedly connected between two balance chambers 20, and liquid control check valve 240 is fixedly connected at the connection of delivery pipe 24 and balance chamber 20. In actual life, the existing device usually needs to carry out concrete pouring treatment on the railway construction site when carrying out railway construction. In the pouring process, due to the weight change influence of concrete and the change of pouring site, the load (personnel, tools and materials) cannot be evenly distributed on both sides of the platform, and the load is concentrated on one side or edge of the platform, so that the gravity center of the platform deviates, an additional overturning moment is generated, the angle of the construction platform changes, and the construction platform is inclined. The existing device cannot timely process the inclination angle of the construction platform, and only adjusts the load to keep the construction platform balanced, which is obviously more tedious and significantly reduces the railway construction efficiency. The utility model discloses a kind of construction platform based on high-rise steel structure, when participating in railway construction, construction personnel of railway construction can stand in the inside of construction chamber 3 and close opening and closing door, operating personnel located at mobile chassis 1 can open scissor lift structure 10 by control center, scissor lift structure 10 drives balance plate 2, construction chamber 3 to move upwards, until construction chamber 3 moves to railway construction area, at this time, construction personnel can normally carry out railway construction treatment, the top of two balance chambers 20 inside is respectively loaded with buffer liquid, when the construction platform is inclined due to load change in the inside of construction chamber 3, for example, Figure 4When the right side of the construction platform appears to be tilted, the construction platform gives the connecting piece 31 at this position a downward force through the first rotating piece 30 at the right side, so that the connecting piece 31 at this position moves downward, and the downward movement of the connecting piece 31 drives the right side of the balance chamber 20 to move downward. Since the right side of the fixed plate 230 is fixedly connected at the top of the balance plate 2, the right side of the fixed plate 230 does not move during the downward movement of the right side of the balance chamber 20, that is, the right side of the top column 23 and the right side of the piston plate 21 do not move, so that the right side of the piston plate 21 keeps the original height unchanged during the downward movement of the right side of the balance chamber 20. At this time, the loadable capacity of the buffer liquid in the right side of the balance chamber 20 is reduced, so that the air pressure in the right side of the balance chamber 20 increases and a part of the buffer liquid is transported into the left side of the balance chamber 20 through the conveying pipe 24. The hydraulic control one-way valve 240 at the right side is used to avoid the backflow of the buffer liquid into the right side of the balance chamber 20. After obtaining this part of the buffer liquid in the left side of the balance chamber 20, the air pressure in the left side of the balance chamber 20 increases. Since the left side of the balance chamber 20 is fixedly connected with the balance plate 2, the left side of the balance chamber 20 cannot move, that is, the left side of the piston plate 21, the left side of the top column 23 and the left side of the fixed plate 230 can move up and down. At this time, the increase of the air pressure in the left side of the balance chamber 20 drives the left side of the piston plate 21 to move downward, and the downward movement of the left side of the piston plate 21 causes the elastic deformation of the elastic piece 220 and drives the left side of the fixed plate 230 to move downward through the left side of the top column 23. The movement of the left side of the fixed plate 230 drives the left side of the construction platform to move downward through the left side of the connecting piece 31 and the left side of the first rotating piece 30. The two first rotating pieces 30 and the two connecting pieces 31 simultaneously limit the construction platform. When the air pressures in the two balance chambers 20 are the same, the construction platform keeps the horizontal height, so that the device completes the automatic correction of the construction platform when the load changes or the construction platform tilts. Since the weight in the construction chamber 3 does not continue to increase after the construction chamber 3 rises in the Figure 4 As shown in the figure, the right side of the construction chamber 3 continuously applies the force and the force no longer continues to increase after the construction chamber 3 rises, and the two balance chambers 20 only need to balance once to continuously keep the horizontal height of the construction chamber 3. In the case that the weight (concrete, putty, etc.) is continuously reduced by spraying, the two balance chambers 20 can continuously adjust the tilting degree of the construction chamber 3 as the weight continuously reduces, so as to make the tilting degree of the construction chamber 3 as small as possible to not cause safety hazards to the construction personnel. Figure 4 When the left side of the construction platform appears to be tilted in the device, the device can adjust in the same way, and only the liquid conveying directions of the two hydraulic control one-way valves 240 are opposite at this time. This is the only different step. The device can automatically complete the adjustment of the construction platform without significantly reducing the railway construction efficiency, which is convenient for users to use. Please refer to Figures 4 to 8Further in the foregoing description, the reset structure 22 comprises a blocking frame 223, the inside of the blocking frame 223 is provided with two elastic members 220, and the elastic members 220 near the balance chamber 20 are respectively arranged between the piston plate 21 and the inner wall of the bottom side of the balance chamber 20, the top and bottom of the elastic member 220 are fixedly connected with the mounting plate 221, the top of the mounting plate 221 is fixedly connected with the clamping plate 222, the two mounting plates 221 on one side of the top are slidingly connected with the blocking frame 223 at the position, the two mounting plates 221 on the other side of the bottom are slidingly connected with the blocking frame 223 at the position, the two mounting plates 221 near the balance chamber 20 and located on the top are clamped with the piston plate 21 and the inner wall of the bottom side of the balance chamber 20 through the two clamping plates 222 on the top and the clamping grooves opened on the piston plate 21 and the inner wall of the bottom side of the balance chamber 20, and the rear end of the balance chamber 20 is not closed, the inner wall of the blocking frame 223 is fixedly connected with the sealing plate, and the inner walls of the blocking frame 223 near the balance chamber 20 are tightly attached to the left and right surfaces of the balance chamber 20; The blocking frame 223 can be used for blocking treatment in the case of the balance chamber 20, so that the balance chamber 20 maintains a sealed space, the elastic member 220 is used for subsequent reset of the equipment through elastic deformation of the elastic member 220 after the railway construction treatment of the construction personnel is completed, to assist in adjusting the air pressure and the buffer liquid in the two balance chambers 20 to the initial state again, so that the reset treatment of the construction platform is completed, the design of the clamping groove and the clamping block is used for subsequent replacement treatment of the elastic member 220, and the sliding connection of the two mounting plates 221 on one side of the top with the blocking frame 223 at the position and the sliding connection of the two mounting plates 221 on the other side of the bottom with the blocking frame 223 at the position are used for avoiding interference with the movement of the piston plate 21 on the left side and the balance chamber 20 on the right side when the piston plate 21 on the left side and the balance chamber 20 on the right side move, and also can limit the movement of the elastic member 220 to a certain extent, to avoid the deflection of the elastic member 220 when the elastic member 220 is elastically deformed or reset, so that the elastic member 220 is difficult to complete the reset subsequently; Figure 4 The blocking frame 223 can be used for blocking treatment in the case of the balance chamber 20, so that the balance chamber 20 maintains a sealed space, the elastic member 220 is used for subsequent reset of the equipment through elastic deformation of the elastic member 220 after the railway construction treatment of the construction personnel is completed, to assist in adjusting the air pressure and the buffer liquid in the two balance chambers 20 to the initial state again, so that the reset treatment of the construction platform is completed, the design of the clamping groove and the clamping block is used for subsequent replacement treatment of the elastic member 220, and the sliding connection of the two mounting plates 221 on one side of the top with the blocking frame 223 at the position and the sliding connection of the two mounting plates 221 on the other side of the bottom with the blocking frame 223 at the position are used for avoiding interference with the movement of the piston plate 21 on the left side and the balance chamber 20 on the right side when the piston plate 21 on the left side and the balance chamber 20 on the right side move, and also can limit the movement of the elastic member 220 to a certain extent, to avoid the deflection of the elastic member 220 when the elastic member 220 is elastically deformed or reset, so that the elastic member 220 is difficult to complete the reset subsequently; Please refer to Figures 5 to 7 Further in the foregoing description, the balance plate 2 is fixedly connected with two exchange assemblies 25 on the top rear side, and the two exchange assemblies 25 are respectively arranged near one end of the two balance chambers 20, the exchange assembly 25 comprises a first rotary driving assembly 250, which is a driving motor, the bottom output end of the first rotary driving assembly 250 is fixedly connected with a rotating rod 251, the bottom of the rotating rod 251 is fixedly connected with a connecting disc 252, the front end and the rear end of the connecting disc 252 are fixedly connected with a grouping plate 253, two linear driving assemblies 254 are fixedly connected with the end of the grouping plate 253 away from the connecting disc 252, the linear driving assembly 254 is a hydraulic cylinder, and the end output end of the linear driving assembly 254 away from the grouping plate 253 is fixedly connected with the reset assembly; When the construction platform is used for a long time, the elastic member 220 may be difficult to elastically deform and reset due to long-term elastic deformation, and the operator at the moving base 1 after the construction is completed can determine whether the elastic member 220 is elastically deformed and fatigued and whether the elastic member 220 needs to be replaced by observing whether the horizontal of the construction platform after reset is inclined. When the construction platform remains inclined after reset, that is, the elastic member 220 is elastically fatigued and difficult to elastically deform and reset, the operator can open the four linear drive assemblies 254 at the front end by the control center, the four linear drive assemblies 254 are opened to drive the reset structure 22 at the front end to separate from the two balance chambers 20, and the first rotary drive assembly 250 is opened by the control center. The first rotary drive assembly 250 is opened to drive the rotating rod 251 to rotate, the rotating rod 251 drives the connecting disc 252 to rotate, the connecting disc 252 drives the four linear drive assemblies 254 to rotate through the grouping plate 253 until the four elastic members 220 originally at the rear side are opposite to the two balance chambers 20 at the front end, and the four elastic members 220 originally used are at the rear side of the two balance chambers 20. At this time, the linear drive assembly 254 at this position is opened by the control center, the linear drive assembly 254 is opened to drive the reset structure 22 to move towards the balance chamber 20, until the two blocking frames 223 block the two balance chambers 20, the clamping plates 222 at the top and bottom of the unused elastic member 220 are clamped in the clamping groove at the bottom of the piston plate 21 and the inner wall at the bottom side of the balance chamber 20, and the operator can also supplement the buffer liquid in the two balance chambers 20 during this period. When the above steps are completed, the equipment completes the replacement of the reset structure 22, avoids the situation that the elastic member 220 cannot elastically deform and reset due to long-term use and elastic deformation fatigue, and the construction platform is difficult to reset, thereby facilitating the use of the user. Please refer to Figures 3 to 9 Further in the above description, the front end extension portion of the connecting piece 31 is provided with a fixing groove 310, the bottom of the construction chamber 3 is fixedly connected with a fixed chamber 4 symmetrically at both sides, the front end inner wall of the fixed chamber 4 is fixedly connected with a second rotary drive assembly 40, the second rotary drive assembly 40 is a driving motor, the rear end output end of the second rotary drive assembly 40 is fixedly connected with a screw rod 41, the outer surface of the screw rod 41 is threadedly connected with a push rod 42 and the push rod 42 penetrates and extends to the rear end outside of the fixed chamber 4, the push rod 42 is rectangular, one end of the push rod 42 close to the second rotary drive assembly 40 is fixedly connected with a limiting sleeve 420, and the extension portion of the push rod 42 is fixedly connected with a fixed block 421 which is the same in shape and size as the fixed block 421, and the total mass of the four reset structures 22 is the same as the total mass of the two fixed chambers 4. During the steps of marking spraying and electrical wiring in railway construction, it is difficult to form an impression of the load of the construction platform because small equipment is used. However, when the vibration caused by the movement of the train in the railway construction environment resonates and causes the construction platform to resonate, the construction platform will not tilt at a large angle at this time, but the vibration of the construction platform will repeatedly exert force on the connecting member 31 through the first rotating member 30, causing the buffer liquid to appear in the two balance chambers 20. After adjustment, the construction platform tilts, that is, the two balance chambers 20 are accidentally touched. At this time, the operator at the mobile chassis 1 can turn on the two second rotary drive assemblies 40 through the control center. The two second rotary drive assemblies 40 are turned on to drive the two screws 41 to rotate. The rotation of the screw 41 drives the push rod 42 to move backward, and the movement of the push rod 42 drives The fixing block 421 moves toward the fixing groove 310 until the fixing block 421 is engaged with the inside of the fixing groove 310. The device adopts a driving motor, a screw 41, and a push rod 42 to replace the common hydraulic cylinder and air cylinder. On the one hand, the driving motor has a faster response. On the other hand, the screw 41 and the push rod 42 have a self-locking property, which makes the connection between the fixing block 421 and the fixing groove 310 tighter. At the same time, unlike the hydraulic cylinder that consumes a lot of energy to keep it fixed, this connection mode has lower energy consumption and is more suitable for use in railway construction. After the fixing block 421 is engaged with the fixing groove 310, the first rotating member 30 and the connecting member 31 cannot continue to rotate, and the two balancing chambers 20 can no longer produce the adjustment of the buffer liquid, that is, the two balancing chambers 20 will not be accidentally touched, which is convenient for users to use. 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; See also Figures 1 to 4 , further in the above description, a second rotating member 32 is fixedly connected to the bottom center of the construction room 3, and an opening and closing door is rotatably connected to the front end of the construction room 3; The second rotating member 32 is used to connect an external ladder. When construction workers on the ground need to go up, they can use the ladder to climb into the construction room 3 without having to reset the scissor-type lifting structure 10, which is convenient for users to use. See also Figures 1 to 2 Further in the above description, the mobile chassis 1 is composed of a frame, a travel drive structure, a steering assembly, four tires, a power source, an emergency stop system and a control center. The frame and the travel drive structure, the steering assembly and the four tires are fixedly connected to each other, and the power source is electrically connected to the travel drive structure, the emergency stop system and the control center.
