Description
Technical Field
[0001] The invention relates to the field of concrete construction, and in particular to a self-propelled construction platform and a construction method suitable for arch bridge outsourcing concrete construction. Background Art
[0002] (1) The movement of the construction platform in traditional outsourced concrete construction requires the use of lifting equipment such as cable cranes and tower cranes. The process is complicated and the construction efficiency is low. In addition, during the outsourced concrete construction process, cable cranes and tower cranes are mainly responsible for the transfer of materials and equipment. The task is heavy and often cannot meet the needs of the construction platform movement, making the entire outsourced concrete construction inefficient.
[0003] (2) When lifting with lifting equipment such as cable cranes and tower cranes, there is too much cross-operation between the lifting equipment, and the lifting ropes are prone to collide with other structures, which can easily affect the construction of other work surfaces and further reduce the efficiency of outsourced concrete construction.
[0004] (3) Conventional sliding trolleys are prone to tilting and deviating during movement, causing movement jams and requiring repeated adjustments during movement, resulting in low construction efficiency.
[0005] (4) Each set of conventional sliding trolleys needs to be equipped with a traction system. For outsourced concrete construction with multiple working surfaces, the large number of platforms requires more traction equipment, which requires a large amount of equipment investment and requires many operators, making management cumbersome and uneconomical. Summary of the invention
[0006] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a self-propelled construction platform and construction method suitable for arch bridge external concrete construction. The self-propelled construction platform adopts a double-rope circular traction method, which can automatically balance the traction force at both ends of the trolley, so that the trolley can move forward smoothly, solving the problem that the conventional sliding trolley is easy to be skewed and offset; the self-propelled construction platform is also suitable for external steel bar construction platform and formwork construction platform, and steel bar construction and formwork construction can be carried out simultaneously without interfering with each other.
[0007] The present invention is implemented by constructing a self-propelled construction platform suitable for arch bridge outer concrete construction, characterized in that: the self-propelled construction platform comprises a sliding trolley, a sliding trolley track, a construction platform, a connecting rope, and a traction system; The sliding trolley adopts a crossbeam and a longitudinal beam to form an overall frame structure, and reinforcement and stabilization measures are arranged in the frame structure to ensure the stability of the frame structure; columns and rollers are arranged under the sliding trolley frame for the sliding trolley to walk on the track; two steering wheels are arranged at the front end of the sliding trolley frame for the traction rope to provide traction; at the same time, the lifting points of the lifting rope are arranged on the sliding trolley, and the lifting points of the lifting rope correspond to the lifting points of the construction platform; The sliding trolley track adopts a special track matched with the roller, and the track is fixed on the arch rib. The track installation ensures that the track is fixed relative to the arch rib axis and the distance between the two tracks remains fixed; The construction platform adopts a construction platform with a stable structure, and the lifting point of the construction platform corresponds to the lifting point of the sliding trolley, and the specifications and length of the lifting rope are determined according to the actual situation; The traction system consists of two winches and traction ropes. The two winches are arranged outside the working area of the sliding trolley. Both ends of a single traction rope are retracted into the winches. The traction rope is routed through the steering wheel of the sliding trolley to connect the traction system with the sliding trolley.
[0008] A self-propelled construction method suitable for arch bridge outsourcing concrete construction, the self-propelled construction platform operation process includes: (1) Track installation: The self-propelled construction platform tracks are laid across the entire construction surface. During track installation, the tracks are ensured to be placed smoothly without tilt or distortion. After the tracks are placed, a total station is used to accurately measure the tracks. The measurement points include at least the two end points and the midpoint of the tracks. Fine-tuning is performed based on the measurement data. During the fine-tuning process, a level ruler is used to check the track for tilt and distortion to ensure that the track is positioned normally without tilt or distortion. (2) Processing of sliding trolley: First, weld the roller to the column. After welding, weld the other end of the column to the beam. Before welding, check the verticality between the column and the beam to ensure that the column and the beam are perpendicular to each other. Check the spacing between the two rollers to ensure that the spacing between the rollers matches the spacing between the tracks. After all indicators are checked and qualified, weld the beam and the column. After the cross beams and columns are assembled, the longitudinal beams are installed. First, a seat is set under the two ends of the two cross beams to fix the two cross beams vertically. The seat setting ensures that the cross beams are placed stably. After the cross beams are placed, the longitudinal beams are welded. After the cross beam and the load-bearing longitudinal beam are assembled and welded, the overall frame structure of the trolley is completed, and then the components such as the lifting rope and the steering wheel of the sliding trolley are installed; (3) Lifting of the sliding trolley: After the manufacturing acceptance of the sliding trolley is completed at the manufacturing site, it is transported to the lifting range of the lifting equipment on the arch rib. Before lifting, the lifting capacity of the lifting equipment must be verified to ensure that the lifting of the sliding trolley can be completed smoothly; before lifting the sliding trolley, the fixing device of the sliding trolley must be completed above the arch rib to ensure that the sliding trolley can be fixed after installation; use the lifting equipment to lift the sliding trolley to the position of the thrust device and place the rollers of the sliding trolley on the track; (4) Installation of the construction platform: The construction platform is hoisted with a special hoist. The platform structure must be stable before and after the construction platform is hoisted, and the platform connection measures must be prepared in advance. After the platform is hoisted to the bottom of the sliding trolley, the construction platform hoisting rope is installed. After the construction platform hoisting rope is installed, the construction platform hoist is slowly loosened to allow the rope to be stressed. The construction platform can be put into use only after the installation is completed and accepted; (5) Traction system installation: Each traction system consists of two winches and traction ropes. The winches must be placed on a stable foundation. The traction ropes must be long enough to cover all self-propelled construction platforms. The traction rope passes through the two steering wheels of the sliding trolley to form a double-circulation traction. This traction method makes the traction force on both sides of the sliding trolley self-balanced, ensuring the smooth movement of the sliding trolley; (6) Inspection before moving the self-propelled construction platform: Before each movement of the self-propelled construction platform, a safety inspection of the self-propelled construction platform and related facilities is required to ensure that the structure of the sliding trolley is intact, the winch equipment is operating normally, the connection between the construction platform and the sliding trolley is firm, the items on the construction platform are firmly fixed, the traction rope is reliably connected, and there is no unnecessary restraint on the sliding trolley; (7) Movement of the self-propelled construction platform: The self-propelled construction platform is moved forward as a whole by two winches that pull it slowly and synchronously. When moving the self-propelled construction platform, first move the self-propelled construction platform forward a small step so that the self-propelled construction platform is completely stressed by the traction rope, then release the locking and fixing constraints of the self-propelled construction platform, and then start the winch to slowly and synchronously pull the self-propelled construction platform to the target position; (8) Locking and fixing of the self-propelled construction platform: When the self-propelled construction platform reaches the target position, the entire self-propelled construction platform needs to be locked and fixed. Since the traction rope needs to work back and forth on multiple platforms, it is impossible to use the traction rope to fix the self-propelled construction platform for a long time. Consider using a thrust device to limit the movement of the rollers at the rear wheels of the sliding trolley to lock the entire self-propelled construction platform, or use a wire rope to pull the sliding trolley to lock the self-propelled construction platform; (9) Use the same traction system to move the next platform: All sliding trolleys on the same track can share one traction system. When the self-propelled construction platform has reached its destination, the traction rope is transferred from the self-propelled construction platform that has completed traction to the next self-propelled construction platform to be moved; To transfer the traction rope, the steel wire rope can be removed by disassembling the steering wheel cake of the sliding trolley, and then the traction rope can be transferred to the next position of the self-propelled construction platform to be moved, and the traction rope can be installed by disassembling the steering wheel cake of the sliding trolley; Alternatively, a steel wire rope is reserved at the steering wheel of each sliding trolley. After the self-propelled construction platform moves to its position, the connection between the traction rope and the reserved steel wire rope is disconnected, and then the traction rope is transferred to the position of the next self-propelled construction platform to be moved, and the traction rope is connected to the reserved steel wire rope of the platform to complete the transfer of the traction system.
[0009] The present invention has the following advantages: (1) The construction platform is a self-propelled construction platform. The platform can move independently without relying on lifting equipment such as cable cranes and tower cranes, thereby ensuring the timeliness of the movement of the construction platform and the template, reducing the workload of the lifting equipment, and improving the efficiency of outsourced concrete construction; (2) The self-propelled construction platform adopts a double-rope circular traction method, which can automatically balance the traction force at both ends of the trolley, so that the trolley can move forward smoothly, solving the problem that the conventional sliding trolley is prone to tilting and deflection; (3) The self-propelled construction platform is suitable for both outsourced steel bar construction platforms and template construction platforms, and steel bar construction and template construction can be carried out simultaneously without interfering with each other; (4) The self-propelled construction platform can quickly and flexibly adjust its position according to the requirements of working surface division or construction needs, accurately control the steel bar construction range and template positioning on the platform, and is particularly suitable for outsourced ring-sectioned multi-working surface construction; (5) The self-propelled construction platform only uses one set of traction system to move multiple sets of platforms, reducing the amount of traction equipment and site occupation.

DETAILED DESCRIPTION
[0011] The following will be combined with the attached Figure 1-Figure 15 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0012] The present invention provides a self-propelled construction platform suitable for arch bridge outer concrete construction, as shown in the figure, which can be implemented in the following manner; the self-propelled construction platform comprises a sliding trolley, a sliding trolley track, a construction platform, a connecting rope, and a traction system; (1) Sliding trolley: The sliding trolley uses cross beams and longitudinal beams to form an overall frame structure, and reinforcement and stabilization measures are set inside the frame structure to ensure the stability of the frame structure. Columns and rollers are set under the sliding trolley frame for the sliding trolley to travel on the track. Two steering wheels are set at the front end of the sliding trolley frame for the traction rope to provide traction. At the same time, the lifting points of the lifting rope are arranged on the sliding trolley, and the lifting points of the lifting rope correspond to the lifting points of the construction platform. Figure 1 Front view of the skid trolley structure, Figure 2 Sliding trolley side view structure diagram, Figure 3 Top view of the skid trolley structure, Figure 4 Schematic diagram of the steering wheel of the skid trolley.
[0013] (2) Sliding trolley track: The sliding trolley track adopts a special track matched with rollers. The track is fixed on the arch rib. The track installation ensures that the track is fixed relative to the arch rib axis and the distance between the two tracks remains fixed. Figure 5 Schematic diagram of the skid trolley rollers and tracks.
[0014] (3) Construction platform and connecting rope: The construction platform adopts a stable structural structure, and the lifting point of the construction platform corresponds to the lifting point of the sliding trolley. The specifications and length of the lifting rope are determined according to the actual situation. Figure 6 Schematic diagram of the sliding trolley lifting rope and construction platform.
[0015] (4) Traction system: The traction system consists of two winches and traction ropes. The two winches are arranged outside the working area of the sliding trolley. Both ends of the single traction rope are retracted into the winches. The traction rope is routed through the steering wheel of the sliding trolley to connect the traction system with the sliding trolley. Figure 7 Schematic diagram of the traction system.
[0016] Self-propelled construction platform operation process: (1) Track installation: The self-propelled construction platform track is laid throughout the entire construction surface. When the track is installed, it is ensured to be placed smoothly, without tilt or distortion. After the track is placed, the track is accurately measured using a total station. The measurement points include at least the two end points and the midpoint of the track. Fine-tuning is performed based on the measurement data. During the fine-tuning process, a level ruler is used to check the track tilt, distortion, etc. to ensure that the track is normally offset and has no tilt or distortion.
[0017] (2) Sliding trolley processing: First, weld the roller to the column. After welding, weld the other end of the column to the beam. Before welding and fixing, check the verticality between the column and the beam to ensure that the column and the beam are perpendicular to each other. Check the spacing between the two rollers to ensure that the spacing between the rollers matches the spacing between the tracks. After all indicators have been checked and passed, weld and fix the beam and column. Figure 8 Schematic diagram of the welding of the sliding trolley column.
[0018] After the crossbeams and columns are assembled, the longitudinal beams are installed. First, the tire seats are set under the two ends of the two crossbeams to fix the two crossbeams vertically. The tire seats are set to ensure that the crossbeams are placed stably. After the crossbeams are placed, the longitudinal beams are welded. Fig. 9 Schematic diagram of making the tire seat using a sliding trolley.
[0019] After the crossbeam and the load-bearing longitudinal beam are assembled and welded, the overall frame structure of the trolley is completed, and then the lifting ropes, lifting points, steering wheels and other components of the sliding trolley are installed.
[0020] (3) Lifting with skid trolley: After the skid trolley is manufactured and inspected at the manufacturing site, it is transported to the lifting range of the lifting equipment on the arch rib. Before lifting, the lifting capacity of the lifting equipment must be verified to ensure that the skid trolley can be lifted smoothly. Before lifting the skid trolley, the fixing device of the skid trolley must be completed above the arch rib to ensure that the skid trolley can be fixed after installation. Use the lifting equipment to lift the skid trolley to the position of the thrust device and place the skid trolley rollers on the track. Fig.10 Schematic diagram of skid trolley installation.
[0021] (4) Construction platform installation: The construction platform is hoisted with a special hoist. The platform structure must be stable before and after the hoisting, and the platform connection measures must be prepared in advance. After hoisting to the bottom of the sliding trolley, the construction platform hoisting rope is installed. After the construction platform hoisting rope is installed, slowly loosen the construction platform hoisting device to make the rope bear force. The construction platform can be put into use only after the installation is completed and accepted. Fig.11 Schematic diagram of construction platform installation.
[0022] (5) Traction system installation: Each traction system consists of two winches and traction ropes. The winches must be placed on a stable foundation. The traction ropes must be long enough to cover all self-propelled construction platforms.
[0023] The traction rope passes through the two steering wheels of the sliding trolley to form a double-circulation traction. This traction method makes the traction force on both sides of the sliding trolley self-balanced, ensuring the smooth movement of the sliding trolley. Fig.12 Schematic diagram of the traction system.
[0024] (6) Inspection before moving the self-propelled construction platform: Before each movement of the self-propelled construction platform, a safety inspection must be carried out on the self-propelled construction platform and related facilities to ensure that the structure of the sliding trolley is intact, the winch equipment is operating normally, the connection between the construction platform and the sliding trolley is firm, the items on the construction platform are firmly fixed, the traction rope is reliably connected, and the sliding trolley has no unnecessary constraints.
[0025] (7) Movement of self-propelled construction platform: The mobile self-propelled construction platform is pulled slowly and synchronously by two winches to move the self-propelled construction platform forward as a whole.
[0026] When moving the self-propelled construction platform, first move the self-propelled construction platform forward a small step so that the self-propelled construction platform is completely stressed by the traction rope, then release the locking and fixing constraints of the self-propelled construction platform, and then start the winch to slowly and synchronously pull the self-propelled construction platform to the target position.
[0027] (8) Locking and fixing of self-propelled construction platform: When the self-propelled construction platform reaches the target location, the entire self-propelled construction platform needs to be locked and fixed. Because the traction rope needs to work back and forth on multiple platforms, it is impossible to use the traction rope to fix the self-propelled construction platform for a long time. Consider using a thrust device to limit the movement of the rollers at the rear wheels of the sliding trolley to lock the entire self-propelled construction platform, or use a wire rope to pull the sliding trolley to lock the self-propelled construction platform. Fig.13 Schematic diagram of the thrust device fixing the sliding trolley, Fig.14 Schematic diagram of the wire rope fixed sliding trolley.
[0028] (9) Use the same traction system to move the next platform: All the sliding trolleys on the same track can share one traction system. When the self-propelled construction platform moves to its position, the traction rope is transferred from the self-propelled construction platform that has completed traction to the next self-propelled construction platform that needs to be moved.
[0029] The traction rope can be transferred by disassembling the steering wheel cake of the sliding trolley to remove the wire rope, and then transferring the traction rope to the next position of the self-propelled construction platform to be moved, and installing the traction rope by disassembling the steering wheel cake of the sliding trolley in the same way.
[0030] Alternatively, a steel wire rope is reserved at the steering wheel of each sliding trolley. After the self-propelled construction platform moves to its position, the connection between the traction rope and the reserved steel wire rope is disconnected, and then the traction rope is transferred to the position of the next self-propelled construction platform to be moved, and the traction rope is connected to the reserved steel wire rope of the platform to complete the transfer of the traction system. Fig.15 Schematic diagram of the shared traction system of multiple self-propelled construction platforms (before and after the traction rope is transferred).
[0031] This patent has the following advantages and beneficial effects: (1) The construction platform is a self-propelled construction platform. The platform can move independently without relying on lifting equipment such as cable cranes and tower cranes, which ensures the timeliness of the movement of the construction platform and formwork, reduces the workload of the lifting equipment, and improves the efficiency of outsourced concrete construction.
[0032] (2) The self-propelled construction platform adopts a double-rope circular traction method, which can automatically balance the traction force at both ends of the trolley, so that the trolley can move forward smoothly, solving the problem that conventional sliding trolleys are prone to tilting and deflection.
[0033] (3) The self-propelled construction platform is suitable for both the outsourced steel bar construction platform and the formwork construction platform, and the steel bar construction and formwork construction can be carried out simultaneously without interfering with each other.
[0034] (4) The self-propelled construction platform can quickly and flexibly adjust its position according to the requirements of work surface division or construction needs, and accurately control the steel bar construction range and template positioning on the platform. It is particularly suitable for outsourced multi-work surface construction in rings and segments.
[0035] (5) The self-propelled construction platform only uses one traction system to move multiple platforms, reducing the amount of traction equipment and site occupation.
