Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to a mobile operating platform for wet joint construction. Background Technology

[0002] A wet joint is a connection method in which a gap of a certain width is left between two adjacent precast beams. After the beams are erected, concrete or other filling materials are poured into the gap to connect the adjacent beams into a whole. It enables adjacent beams to work together and jointly bear vehicle loads and other external forces, enhancing the integrity and stability of the bridge structure, thereby improving the bridge's load-bearing capacity and durability.

[0003] When performing transverse tensioning, grouting, or sealing of wet joints, workers need to be positioned outside the beam and suspended in mid-air. Current techniques often involve attaching ladders to the retaining wall of the beam, with workers standing on the ladders to perform the work. This is difficult and dangerous. Other methods involve erecting simple scaffolding on one side of the beam; however, once the work at the current location is completed, the scaffolding must be dismantled and re-erected at the next location, which is time-consuming and labor-intensive, severely impacting construction efficiency and compromising worker safety. Utility Model Content

[0004] This utility model provides a mobile operating platform for wet joint construction, aiming to solve the technical problem in the prior art that the wet joint construction process is time-consuming and laborious due to the lack of a stable and reliable operating platform, and the personal safety of operators cannot be guaranteed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a mobile operating platform for wet joint construction, comprising:

[0006] The mounting frame is suspended on the retaining wall of the beam, and the mounting frame is connected to the traveling wheels, which roll in cooperation with the top surface of the retaining wall.

[0007] A platform frame, connected below the mounting bracket and located on the outside of the beam, is connected to a chain for securing it to the beam; and

[0008] A ladder frame, connected between the mounting frame and the platform frame, is used to allow operators to pass between the platform frame and the top surface of the beam.

[0009] In one possible implementation, the mounting bracket is further connected to a first positioning wheel group and a second positioning wheel group arranged opposite to each other. The first positioning wheel group rolls with the inner sidewall of the retaining wall, and the second positioning wheel group rolls with the outer sidewall of the retaining wall.

[0010] In some embodiments, the second positioning wheel assembly includes a wheel frame hinged to the mounting bracket and a second positioning wheel rotatably connected to the wheel frame. The second positioning wheel rolls in engagement with the outer wall of the retaining wall, and the wheel frame is used to drive the second positioning wheel to swing vertically along the length of the beam.

[0011] In some embodiments, the wheel frame is provided with an arc-shaped cover for covering the outer periphery of the second positioning wheel.

[0012] In some embodiments, the mounting bracket includes:

[0013] A top beam, located above the retaining wall and connected to the upper end of the ladder frame; and

[0014] The inner stop arm is connected to the inner end of the top beam and is located on the inner side of the retaining wall;

[0015] A hinge seat is connected to the bottom wall of the top beam, and the wheel frame is hinged to the hinge seat.

[0016] In some embodiments, the walking wheel is rotatably connected to the underside of the top beam via a rotating shaft, and a rotary drive component is connected to the top wall of the top beam. The rotary drive component has a horizontally extending drive shaft, and the rotating shaft and the drive shaft are connected by a transmission assembly.

[0017] In some embodiments, the first positioning wheel assembly includes a rotating seat connected to the inner stop arm and a first positioning wheel rotatably connected to the rotating seat, wherein the first positioning wheel and the second positioning wheel are arranged correspondingly inside and outside.

[0018] In one possible implementation, the platform frame includes:

[0019] A support plate, connected to the lower end of the ladder frame, extends horizontally towards one side of the beam; and

[0020] A fence is attached above the support plate and extends circumferentially along the outer edge of the support plate;

[0021] The lower end of the chain is attached to the fence.

[0022] In some embodiments, an auxiliary wheel is rotatably connected to the inner edge of the support plate, the main shaft of the auxiliary wheel extends in the vertical direction, and the auxiliary wheel rolls in cooperation with the side wall of the beam.

[0023] In one possible implementation, the ladder frame includes an upper crossbeam, a lower crossbeam, and a plurality of columns spaced apart between the upper crossbeam and the lower crossbeam. The mounting frame is connected to the inner side of the upper crossbeam, and the platform frame is connected to the inner side of the lower crossbeam. A ladder is provided between two adjacent columns.

[0024] The advantages of this mobile operating platform for wet joint construction are as follows: By installing wheels on the mounting frame, allowing it to roll along the top surface of the retaining wall, the entire operating platform can be easily moved along the length of the beam, significantly saving transfer time between different construction positions and improving construction efficiency. The platform frame provides operators with a safe and stable construction platform and a storage platform for construction tools. A chain connecting the platform frame to the beam effectively secures the platform frame, ensuring it remains stable and undisturbed during operation, greatly enhancing operator safety. A ladder connects the mounting frame and the platform frame into a single, robust operating platform structure. This facilitates operator movement between the top surface of the beam and the platform frame. When the entire operating platform needs to be moved, operators on the platform frame can climb the ladder and access the top surface of the beam via the mounting frame, avoiding the need for personnel to be carried during movement and further improving operator safety.

[0025] Compared with existing technologies, the mobile operating platform for wet joint construction provided in this embodiment can complete the wet joint construction of the entire bridge length in one go after being placed in place once on the bridge. This reduces the labor intensity of operators, shortens the construction cycle, and greatly improves construction efficiency. At the same time, it provides safe and reliable construction conditions for operators and effectively protects their personal safety. It has high application value in the field of railway bridge construction. Attached Figure Description

[0037] Please refer to the following: Figures 1 to 6This invention provides a mobile operating platform for wet joint construction. The mobile operating platform for wet joint construction includes a mounting frame 1, a platform frame 2, and a ladder frame 3. The mounting frame 1 is suspended from the retaining wall 101 of the beam 10, and is equipped with wheels 11 that roll in contact with the top surface of the retaining wall 101. The platform frame 2 is connected below the mounting frame 1 and located on the outside of the beam 10. A chain 21 is connected to the platform frame 2, and the upper end of the chain 21 is used to fix it to the beam 10. The ladder frame 3 connects the mounting frame 1 and the platform frame 2, allowing operators to pass between the platform frame 2 and the top surface of the beam 10.

[0038] This embodiment provides a mobile operating platform for wet joint construction. By installing wheels 11 on the mounting frame 1, it can roll along the top surface of the retaining wall 101, allowing the entire operating platform to move easily along the length of the beam 10, significantly saving transfer time between different construction locations and improving construction efficiency. The platform frame 2 provides a safe and stable construction platform for operators and a storage platform for construction tools. A chain 21 connects the platform frame 2 to the beam 10, effectively fixing the platform frame 2 and ensuring that it does not shake or sway during operation, greatly enhancing the safety of operators. The ladder frame 3 connects the mounting frame 1 and the platform frame 2 into one unit, forming a stable operating platform structure. It also facilitates the passage of operators between the top surface of the beam 10 and the platform frame 2. When it is necessary to move the entire operating platform, operators on the platform frame 2 can climb up the ladder 34, pass through the mounting frame 1, and enter the top surface of the beam 10, avoiding the need for personnel to move and further improving the safety of operators.

[0039] Compared with existing technologies, the mobile operating platform for wet joint construction provided in this embodiment can complete the wet joint construction of the entire bridge length in one go after being placed in place once on the bridge. This reduces the labor intensity of operators, shortens the construction cycle, and greatly improves construction efficiency. At the same time, it provides safe and reliable construction conditions for operators and effectively protects their personal safety. It has high application value in the field of railway bridge construction.

[0040] In this embodiment, three traveling wheels 11 are spaced apart along the length of the retaining wall 101. The traveling wheels 11 are made of rubber tires and their width is slightly narrower than the width of the retaining wall 101, which further increases the stability of the entire operating platform during movement. The upper end of the chain 21 passes through the drain on the beam 10 and is fixed to the top surface of the beam 10, making it easy for the operator to lower the chain 21 from the top surface of the beam 10.

[0041] When using this operating platform, a crane or similar lifting equipment is first used to raise the entire platform and attach the mounting frame 1 to the retaining wall 101 of the beam 10. Simultaneously, the crane is used to place the tensioning machine, grouting equipment, generator, and other construction tools onto the platform frame 2. When moving the operating platform later, the construction tools do not need to be removed and can move synchronously with the platform, eliminating the need for manual movement of the tools and reducing the labor intensity of the operators.

[0042] After the operator lowers the chain 21 through the drain outlet on the top surface of the beam 10, they use the ladder 3 to descend to the platform frame 2, and then fix the lower end of the chain 21 to the platform frame 2 to ensure that the platform frame 2 will not sway or shake. Furthermore, multiple chains 21 can be installed to fix the platform frame 2 at multiple points, further ensuring the stability of the platform frame 2 and improving the operator's sense of security.

[0043] After securing the platform frame 2 with chain 21, construction operations can commence at the current location. Upon completion of construction at this location, operators first disconnect chain 21 from the platform frame 2, then climb to the top surface of the beam 10 using ladder 3. The platform is then moved to the next construction location using wheels 11, ensuring that no personnel are carried on the platform during movement to guarantee operator safety. This process is repeated until the entire bridge construction is completed. Finally, a mobile crane is used to remove the entire platform and transfer it to the next construction site, enabling reuse of the platform.

[0044] In some embodiments, the mounting bracket 1 and the retaining wall 101 are connected by a method such as Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The mounting bracket 1 is also connected to a first positioning wheel group 12 and a second positioning wheel group 13 that are arranged opposite to each other. The first positioning wheel group 12 rolls with the inner side wall of the retaining wall 101, and the second positioning wheel group 13 rolls with the outer side wall of the retaining wall 101.

[0045] The first positioning wheel set 12 and the second positioning wheel set 13 clamp and limit the entire operating platform from the inside and outside of the retaining wall 101. At the same time, they combine with the traveling wheels 11 to provide travel support on the top surface of the retaining wall 101, forming a stable three-dimensional positioning structure. This effectively prevents the operating platform from shaking, shifting to the side or overturning during construction, ensuring the safety of the operators.

[0046] On the other hand, when the operating platform is moved to the designated construction position, the first positioning wheel set 12 and the second positioning wheel set 13 can be rolled and fitted one by one with the inner and outer walls of the retaining wall 101, so as to quickly and accurately position and install the operating platform, which helps to improve the construction speed.

[0047] In addition, the first positioning wheel set 12 and the second positioning wheel set 13 contact the ballast wall 101 through rolling friction, which greatly reduces the friction between the mounting frame 1 and the ballast wall 101 compared to sliding friction. This not only reduces the wear of the mounting frame 1 and the ballast wall 101, but also reduces the noise generated during the movement of the operating platform.

[0048] In some embodiments, the second positioning wheel set 13 described above adopts the following... Figure 2 The structure shown. See also Figure 2 The second positioning wheel assembly 13 includes a wheel frame 131 hinged to the mounting frame 1 and a second positioning wheel 132 rotatably connected to the wheel frame 131. The second positioning wheel 132 rolls with the outer wall of the retaining wall 101. The wheel frame 131 is used to drive the second positioning wheel 132 to swing vertically along the length of the beam 10.

[0049] It should be noted that multiple T-shaped steel sections 102 are spaced apart on the outer wall of the retaining wall 101. In actual construction scenarios, the T-shaped steel sections 102 can serve as reliable connection points for connecting various ancillary facilities, such as temporary support structures, guardrails, and inspection ladders during construction. Specifically, the upper horizontal plate of the T-shaped steel section 102 is embedded in the retaining wall 101, and the extended plate with multiple mounting holes extends outward from the retaining wall 101.

[0050] Because the second positioning wheel set 13 rolls with the outer wall of the retaining wall 101, when the operating platform moves along the length of the retaining wall 101 and encounters the protruding T-shaped steel 102, the second positioning wheel set 13 needs to cross the T-shaped steel 102 to avoid affecting the movement of the entire operating platform.

[0051] In this embodiment, the hinged connection between the wheel frame 131 and the mounting frame 1 allows the wheel frame 131 to drive the second positioning wheel 132 to swing vertically. When the second positioning wheel 132 contacts the T-shaped steel 102, the T-shaped steel 102 creates resistance to the movement of the second positioning wheel assembly 13. This resistance causes the wheel frame 131 to swing vertically around its hinge point with the mounting frame 1, raising the position of the second positioning wheel 132 accordingly, allowing it to pass over the top of the T-shaped steel 102. After passing over the T-shaped steel 102, the wheel frame 131 drives the second positioning wheel 132 to automatically return to its original position under the influence of gravity. This design avoids the problem of the operating platform being unable to move due to the obstruction of the T-shaped steel 102, ensuring that the operating platform can continuously move along the length of the beam 10, guaranteeing the continuity of wet joint construction, and significantly improving construction efficiency.

[0052] In some embodiments, the wheel frame 131 adopts as follows: Figure 2 and Figure 5 The structure shown. See also Figure 2 and Figure 5The wheel frame 131 is provided with an arc-shaped cover 133 for covering the outer periphery of the second positioning wheel 132. The arc-shaped cover 133 effectively buffers the impact force when the second positioning wheel assembly 13 collides with the T-shaped steel 102, allowing the second positioning wheel 132 to pass over the T-shaped steel 102 more smoothly, avoiding jamming during the movement of the operating platform, and improving the performance of the operating platform.

[0053] Specifically, the process for the second positioning wheel set 13 to cross the T-beam 102 is described in [link to procedure]. Figure 6 As the operating platform moves forward along the length of the beam 10, the second positioning wheel 132, located at the foremost end, first approaches the pre-embedded T-shaped steel 102. Its outer arc-shaped cover 133 first collides with the edge of the T-shaped steel 102. The resistance generated by the collision causes the wheel frame 131 to swing backward and upward around its hinge point with the mounting frame 1. As the operating platform continues to move forward, the T-shaped steel 102 continuously pushes the arc-shaped cover 133 upward, and the position of the second positioning wheel 132 rises accordingly until it passes over the top of the T-shaped steel 102. During this process, the arc-shaped cover 133, with its special arc-shaped structure, guides the second positioning wheel 132 to smoothly cross the T-shaped steel 102, avoiding direct impact and reducing the impact force. After the second positioning wheel 132 passes over the T-shaped steel 102, the wheel frame 131, under the action of gravity, drives the second positioning wheel 132 back down, allowing the second positioning wheel 132 to re-engage with the outer wall of the retaining wall 101, continuing to guide the stable movement of the operating platform. The two second positioning wheel sets 13 located at the rear pass over the T-shaped steel 102 in the same manner, enabling the operating platform to operate continuously across obstacles and ensuring continuous construction of the wet joint.

[0054] In some embodiments, the mounting bracket 1 described above adopts the following... Figure 2 The structure shown. See also Figure 2 The mounting frame 1 includes a top beam 14 and an inner stop arm 15. The top beam 14 is located above the retaining wall 101 and is connected to the upper end of the climbing frame 3. The inner stop arm 15 is connected to the inner end of the top beam 14 and is located on the inner side of the retaining wall 101. A hinge seat 141 is connected to the bottom wall of the top beam 14, and the wheel frame 131 is hinged to the hinge seat 141.

[0055] In this embodiment, three mounting frames 1 are spaced apart along the length of the beam 10, and three traveling wheels 11 are connected to the three mounting frames 1 in a one-to-one correspondence. The top beam 14 and the inner stop arm 15 combine to form a mounting frame 1 with an inverted "L" shape, which allows the mounting frame 1 to be hung more stably on the retaining wall 101, ensuring that the entire operating platform will not tip over. By setting a hinge seat 141 on the bottom wall of the top beam 14, the wheel frame 131 is hinged to the hinge seat 141. On the one hand, this enables the vertical swing of the wheel frame 131. On the other hand, the above arrangement makes the structure of the mounting frame 1 more compact, which to some extent reduces the distance between the climbing frame 3 and the inner stop arm 15, and helps to increase the stability of the entire operating platform.

[0056] Specifically, both the top beam 14 and the inner retaining arm 15 are made of I-beams, which can ensure load-bearing strength, and the use of structural steel as raw material can help reduce production costs.

[0057] In some embodiments, the aforementioned walking wheel 11 and mounting bracket 1 are connected by, for example, Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4 The walking wheel 11 is rotatably connected to the bottom of the top beam 14 via the rotating shaft 16. A rotary drive 17 is connected to the top wall of the top beam 14. The rotary drive 17 has a horizontally extending drive shaft. The rotating shaft 16 and the drive shaft are connected by a transmission assembly 18.

[0058] In this embodiment, the rotary drive component 17 adopts a 220V drive motor. The rotary drive component 17 is set on the top wall of the top beam 14, which optimizes the space utilization and makes the structure of the mounting frame 1 simple and compact. At the same time, using the drive motor as the rotary drive component 17 to drive the rotating shaft 16 to rotate facilitates remote control. Specifically, a control module can be set on the drive motor and equipped with a remote control, so that the operator can remotely control the rotary drive component 17 from a safe position on the top surface of the beam 10, further ensuring the safety of construction.

[0059] Optionally, the transmission assembly 18 includes a first sprocket 181, a second sprocket 182, and a chain 183. The first sprocket 181 is connected to the rotating shaft 16; the second sprocket 182 is connected to the drive shaft; and the chain 183 is sleeved on the outer periphery of the first sprocket 181 and the second sprocket 182 and passes through the top beam 14 in the vertical direction.

[0060] Since the drive shaft is located above the top beam 14 and the rotating shaft 16 is located below the top beam 14, the use of a chain 183 and sprocket transmission ensures transmission stability. Simultaneously, by providing a through hole in the top beam 14, the chain 183 passes through the hole to engage with the first sprocket 181 and the second sprocket 182. This fully utilizes the vertical space of the mounting frame 1, avoids occupying too much space in the horizontal direction, and makes the structure of the mounting frame 1 more compact and the overall layout more reasonable.

[0061] The aforementioned transmission component 18 can also adopt a pulley and transmission belt structure, or a synchronous pulley and synchronous belt structure, without specific limitations.

[0062] In some embodiments, the first positioning wheel set 12 adopts, as follows: Figure 2 The structure shown. See also Figure 2 The first positioning wheel assembly 12 includes a rotating seat 151 connected to the inner stop arm 15 and a first positioning wheel 121 rotatably connected to the rotating seat 151. The first positioning wheel 121 and the second positioning wheel 132 are arranged correspondingly inside and outside.

[0063] In this embodiment, two first positioning wheels 121 and two second positioning wheels 132 are respectively arranged at intervals along the vertical direction. The first positioning wheels 121 and the second positioning wheels 132 are arranged in a one-to-one correspondence between the inner and outer sides to ensure stable and effective support for the operating platform.

[0064] In some embodiments, the platform frame 2 described above adopts, for example... Figure 1 The structure shown. See also Figure 1 The platform frame 2 includes a support plate 22 and a railing 23. The support plate 22 is connected to the lower end of the climbing ladder frame 3 and extends horizontally to one side of the beam 10. The railing 23 is connected to the upper part of the support plate 22 and extends circumferentially along the outer edge of the support plate 22. The lower end of the chain 21 is connected to the railing 23.

[0065] The support plate 22 extends horizontally to one side of the beam 10, providing operators with a spacious and stable standing and operating space. This facilitates wet joint construction on the platform frame 2, reduces fatigue during long hours of work, and helps improve construction efficiency. Simultaneously, the spacious support plate 22 provides storage space for construction tools and materials, preventing clutter caused by haphazard placement and improving site management efficiency.

[0066] The fence 23 extends circumferentially along the outer edge of the support plate 22, forming a continuous protective barrier around the operator, effectively preventing the risk of falling. At the same time, connecting the lower end of the chain 21 to the fence 23 strengthens the connection between the platform frame 2 and the beam 10, further ensuring the safety of the operator.

[0067] Specifically, the support plate 22 can be made by welding I-beams into a frame, and then laying wire mesh or thin steel plates on top of the frame to ensure load-bearing strength while ensuring the flatness of the support surface. The fence 23 is made by welding angle steel and round steel, which reduces the processing and manufacturing cost. The fence 23 is 1.2-1.5 meters high.

[0068] In some possible embodiments, an auxiliary wheel 24 is rotatably connected to the inner edge of the support plate 22. The main shaft of the auxiliary wheel 24 extends in the vertical direction, and the auxiliary wheel 24 rolls with the side wall of the beam 10.

[0069] In this embodiment, the auxiliary wheel 24 rolls in contact with the side wall of the beam 10, adding a support point to the operating platform. Together with the first positioning wheel group 12, the second positioning wheel group 13, and the traveling wheel 11, it forms a stable support system. Under severe weather conditions such as strong winds, or when lateral forces are generated during construction, the auxiliary wheel 24 can provide a reverse support force through close contact with the side wall of the beam 10, effectively resisting the influence of lateral forces, preventing lateral displacement or overturning of the operating platform, and ensuring its stability.

[0070] During the movement of the operating platform, the auxiliary wheel 24 can roll smoothly along the side wall of the beam 10, providing guidance and auxiliary support for the movement of the operating platform, making the movement of the operating platform more flexible and stable.

[0071] In some embodiments, the aforementioned ladder frame 3 adopts, for example... Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The ladder frame 3 includes an upper crossbeam 31, a lower crossbeam 32, and multiple columns 33 spaced apart between the upper crossbeam 31 and the lower crossbeam 32. The mounting frame 1 is connected to the inner side of the upper crossbeam 31, and the platform frame 2 is connected to the inner side of the lower crossbeam 32. A ladder 34 is provided between two adjacent columns 33.

[0072] The upper crossbeam 31, lower crossbeam 32, and multiple columns 33 form a stable ladder frame 3 structure, providing reliable support for the ladder 34. At the same time, the stable ladder frame 3 connects the mounting frame 1 and the platform frame 2 into a single structure, making the entire operating platform an organic whole and enhancing the structural strength and stability of the operating platform.

[0073] Mounting frame 1 is connected to the inner side of the upper crossbeam 31, and platform frame 2 is connected to the inner side of the lower crossbeam 32, so that platform frame 2 and mounting frame 1 are located on the same side of ladder frame 3. This not only facilitates the vertical correspondence of support points and stress points and optimizes the stress on the operating platform, but also allows operators on platform frame 2 to be closer to the construction points on beam 10, making construction operations easier.
