Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction auxiliary equipment, in particular to a walking device for lateral movement of a variable-section continuous beam. Background Art

[0002] Most of the continuous beams have the same cross-sectional width, and the hanging basket construction can be carried out in a conventional way for continuous segment construction. The sliding beam moves in a straight line with the hanging basket, and the sliding beam supports the outer formwork bracket and the outer formwork and is always within the range of the sliding beam hanger.

[0003] When encountering a continuous beam with a variable cross-section width, the traditional hanging basket construction method of the sliding beam moving in a straight line will encounter difficulties because the sliding beam hanger is directly anchored by fine-rolled threaded steel with an anchor beam above the reserved hole in the continuous beam bridge deck and cannot be changed.

[0004] Since the continuous beam becomes wider or narrower, the front end of the sliding beam is supported by the sling to move in a straight line while following the movement of the hanging basket. The width of the sliding beam hanger is limited and has a movement restriction. Once the front end of the sliding beam moves to the maximum limit position of the hanger, it will interfere with the hanger, resulting in the inability to carry out construction. Although the problem of sliding beam movement can be solved by enlarging the reserved holes in the beam body, the steel bars and prestressed tendons in the concrete beam body will interfere with the reserved holes, and will also weaken the structural strength of the beam body, increasing the construction safety risk. Therefore, the plan to enlarge or increase the reserved holes in the beam body is not advisable. Utility Model Content

[0005] In order to solve the technical problem that the existing sliding beam hanger has limited width and cannot support the construction of variable-section continuous beams, the utility model provides a walking device for lateral movement of variable-section continuous beams.

[0006] The technical solution of the utility model is achieved through the following scheme: a walking device for the lateral movement of a variable-section continuous beam, comprising a continuous beam, a rhombus frame, a middle door frame, an outer mold and an outer mold bracket, the rhombus frame is fixedly installed on the top of the continuous beam, the middle door frame is detachably installed on the rhombus frame, the outer mold is located between the continuous beam and the outer mold bracket, the rhombus frame is connected to a plurality of sliding beams through a sling, the outer mold and the outer mold bracket are overlapped on a plurality of sliding beams, a plurality of the sliding beams are overlapped on a sliding beam hanger, the sliding beam hanger is hung on a transverse support frame, the transverse support frame is fixed to the top bridge deck of the continuous beam through a vertical locking rod, and a limiting rod is installed in the sliding beam hanger.

[0007] Through the above technical scheme, the transverse support frame device can flexibly adapt to variable-section continuous beams of different widths and shapes. Through the combination of the sliding beam hanger and the transverse support frame, and the fixation of the vertical locking rod to the top bridge deck of the continuous beam, the entire walking device can maintain a high degree of stability during the lateral movement. By setting a limit rod in the sliding beam hanger, the sliding beam is prevented from excessively moving in the vertical direction, thereby avoiding construction risks caused by excessive changes in the position of the sliding beam, and ensuring safety and reliability during the construction process.

[0008] Preferably, the transverse support frame includes a plurality of hangers and transverse hanger slide rails, the transverse hanger slide rails are overlapped on a plurality of hangers, a sliding beam hanger is fixedly mounted on the transverse hanger slide rails, and the plurality of hangers are fixed to the top bridge deck of the continuous beam by vertical locking rods.

[0009] Preferably, limit plates are provided at both ends of the transverse hanger slide rail, and the limit plates are movably connected to the hanger via a sliding rod, and the sliding rod passes through the hanger.

[0010] Through the above technical solution, by adopting a combination of several hangers and transverse hanger rails, the sliding beam hanger can move more stably in the lateral direction. Multiple hangers reduce the shaking or deviation that may occur during the movement of the sliding beam hanger, thereby improving the stability and safety during the construction process. The limit plate effectively limits the lateral movement to avoid disengagement due to excessive movement, reducing potential safety risks.

[0011] Preferably, the sliding beam hanger includes a first sliding beam hanger and a second sliding beam hanger, the second sliding beam hanger is located between the first sliding beam hanger and the outer mold, the first sliding beam hanger is provided with a supporting roller, the second sliding beam hanger is provided with a lap beam, and limiting rods are installed on the first sliding beam hanger and the second sliding beam hanger.

[0012] Preferably, the sliding beam is overlapped on the second sliding beam hanger through a lap beam, and the sliding beam is overlapped on the first sliding beam hanger through a supporting roller.

[0013] Preferably, the first sliding beam hanger and the second sliding beam hanger are both hung on the transverse support frame.

[0014] Through the above technical scheme, the combined use of the first sliding beam hanger and the second sliding beam hanger enables the sliding beam to obtain more stable support during the lateral movement. The design of the supporting roller makes the sliding beam smoother during the movement, reduces the heat and wear generated by friction, and the lap beam avoids the possible shaking or deviation of the sliding beam during the movement.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. The utility model can flexibly adapt to variable-section continuous beams of different widths and shapes through the transverse support frame device. Through the combination of the sliding beam hanger and the transverse support frame, and the fixation of the vertical locking rod to the top bridge deck of the continuous beam, the entire walking device can maintain a high degree of stability during the lateral movement. By arranging a limit rod in the sliding beam hanger, the sliding beam is prevented from excessively moving in the vertical direction, avoiding the construction risks that may be caused by excessive changes in the position of the sliding beam, and ensuring the safety and reliability of the construction process.

[0017] 2. By adopting a combination of several hangers and transverse hanger rails, the sliding beam hanger can move more stably in the lateral direction. Multiple hangers reduce the shaking or deviation that may occur during the movement of the sliding beam hanger, thereby improving the stability and safety during the construction process. The limit plate effectively limits the lateral movement to avoid disengagement due to excessive movement, reducing potential safety risks.

[0018] 3. The combined use of the first sliding beam hanger and the second sliding beam hanger enables the sliding beam to obtain more stable support during lateral movement. The design of the support roller makes the sliding beam smoother during movement, reduces the heat and wear caused by friction, and the lap beam avoids possible shaking or deviation of the sliding beam during movement.

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

The transverse support frame 1 is anchored by an anchor beam above the reserved hole on the bridge deck of the continuous beam 101 through the finely rolled threaded steel bar, ensuring the stability of the transverse support frame 1 and preventing possible displacement or shaking. The overall hanging installation is under the flange of the continuous beam 101. When the diamond frame 102 is dragged forward by the sling 5, the transverse support frame 1 will also move laterally, thereby driving the sliding beam hanger 2 to move. The sliding beam 4 and the sliding beam hanger 2 can move in a coordinated manner, reducing the downtime adjustment time caused by interference, thereby improving construction efficiency, reducing equipment damage caused by friction, collision, etc., thereby reducing maintenance and disassembly and replacement costs. When the width of the continuous beam 101 changes, the sliding beam hanger 2 and the transverse support frame 1 system can be adjusted accordingly to ensure that the sliding beam 4 can move smoothly and smoothly, thereby ensuring the continuity and efficiency of the construction.

[0031] like Figure 7 and Figure 8 As shown, the transverse support frame 1 includes a plurality of transverse fixed hangers 11 and transverse hanger slide rails 12. The transverse hanger slide rails 12 are overlapped on the plurality of transverse fixed hangers 11. The sliding beam hanger 2 is fixedly installed on the transverse hanger slide rails 12. The plurality of transverse fixed hangers 11 are fixed to the top bridge deck of the continuous beam 101 through the vertical locking rods 8. The number of transverse fixed hangers 11 is preferably two, and the two transverse fixed hangers 11 have a certain distance, so that the transverse hanger slide rails 12 have a high balance no matter how they move transversely. The transverse fixed hanger 11 is claw-shaped, and its transverse hanger slide rails 12 pass through and overlap the transverse fixed hanger 11. On the top, the transverse hanger slide rail 12 and the sliding beam hanger 2 are welded, and limit plates are provided at both ends of the transverse hanger slide rail 12. The limit plates are movably connected to the transverse fixed hanger 11 through the sliding rod 7. The sliding rod 7 runs through the transverse fixed hanger 11. The sliding rod 7 further enhances the flexibility and safety of operation and enhances the overall stability. The limit plates effectively limit the movement range of the slide rail and prevents the slide rail from exceeding the predetermined safety area during movement. The sliding rod 7 runs through the transverse fixed hanger 11 so that the slide rail can cooperate with the transverse fixed hanger 11 to maintain better stability and reliability when it is under load or subjected to external impact.

[0032] like Figure 5 , Figure 6 and Figure 8As shown, the sliding beam hanger 2 includes a first sliding beam hanger 21 and a second sliding beam hanger 22, the second sliding beam hanger 22 is located between the first sliding beam hanger 21 and the outer mold 104, the first sliding beam hanger 21 is provided with a supporting roller 3, the second sliding beam hanger 22 is provided with a lap beam 9, the first sliding beam hanger 21 and the second sliding beam hanger 22 are both installed with a limiting rod 6, the first sliding beam hanger 21 and the second sliding beam hanger 22 have the same external structure, the sliding beam 4 is overlapped on the second sliding beam hanger 22 through the lap beam 9, the sliding beam 4 is overlapped on the first sliding beam hanger 21 through the supporting roller 3, the first sliding beam hanger 21 and the second sliding beam hanger 22 are both hung on the transverse support frame 1, and their hanging and installation are also consistent. The construction personnel can follow the same procedure during installation, and there is no need to install them on both sides. The working method of switching between different types of transverse fixed hangers 11 improves the installation efficiency. The only difference between the first sliding beam hanger 21 and the second sliding beam hanger 22 is that one has wheels and the other does not. To avoid waste, the supporting roller 3 facilitates the feeding and walking of the sliding beam 4. The second sliding beam hanger 22 ensures the stability and balance of the sliding beam 4, reducing the risk of damage or accidents caused by shaking or tilting. The first sliding beam hanger 21 and the second sliding beam hanger 22 are both equipped with a limit rod 6. The first sliding beam hanger 21 and the second sliding beam hanger 22 are both installed with a limit rod 6. The limit rod 6 is used to control the vertical movement range of the sliding beam 4, effectively preventing the sliding beam 4 from accidentally falling or overturning during the lifting process, thereby greatly improving the safety of construction.

[0033] Working principle: the sliding beam 4 passes through the first sliding beam hanger 21 and the second sliding beam hanger 22, and is limited in vertical height by the limit rod 6 on the sliding beam hanger 2. The sliding beam hanger 2 is hung under the flange of the continuous beam 101 by the transverse fixed hanger 11, and the end is fixed to the diamond frame 102 by the sling 5. When the diamond frame 102 drags the sliding beam 4 to move, the sliding beam 4 can easily move and feed with the help of the supporting roller 3. When the continuous beam 101 becomes wider and narrower, when the sliding beam 4 moves to the maximum width of the sliding beam hanger 2, the sliding beam hanger 2 is driven by the force to drive the transverse hanger slide rail 12 welded to it to move transversely on the transverse fixed hanger 11.
