Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a segmental beam steel cage splicing device based on BIM technology. Background Technology

[0002] BIM (Building Information Modeling) technology is an advanced digital technology that plays a crucial role throughout the entire lifecycle of segmental beam reinforcement cages, including design, manufacturing, transportation, and installation. Through BIM technology, functions such as 3D modeling, information integration, simulation analysis, and optimization of segmental beam reinforcement cages can be achieved, thereby improving project quality and construction efficiency.

[0003] Chinese Patent Publication No. CN218757050U discloses a segmental beam reinforcement cage splicing device based on BIM technology, comprising a trolley track, a conveying trolley, a main steel frame, a traveling beam, a suspended traveling device, an assembly template, and a suspended platform mechanism. This solution allows for the factory fabrication of segmental beam reinforcement cages with high precision, unaffected by seasons or weather. After forming the segments, they are transported to the construction site and hoisted to the completed bridge location using specialized equipment. The trolley then transports the cages to the construction location, and the suspended traveling device moves them from the trolley to the construction position. This results in a short hoisting distance, low crane load pressure, and high equipment safety. Furthermore, in conjunction with the assembly template and suspended platform mechanism, the segmental beam reinforcement cages can be accurately delivered to the assembly position. The entire construction process is highly mechanized and automated, reducing on-site personnel and time spent working at heights, further reducing on-site construction risks, and achieving the effects of shortening the construction period, improving construction quality, and being economical and environmentally friendly.

[0004] In the aforementioned prior art, the segmental beam reinforcement cage on the trolley can be sent to the construction position by the set hanging walking device, and the segmental beam reinforcement cage can be hoisted and lifted. However, since the segmental beam reinforcement cage is lifted by hoisting, there is a lack of auxiliary support measures during the lifting process. If the wind force is too strong during the hoisting process, the reinforcement cage may swing or tilt. Therefore, a segmental beam reinforcement cage splicing device based on BIM technology is needed to meet people's needs. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a segmental beam reinforcement cage splicing device based on BIM technology, including a segmental beam 100, a conveying trolley 101 and an assembly template 106 mounted on the segmental beam 100, a traveling beam 102 mounted on the conveying trolley 101, a traveling crane 103 movably mounted on the traveling beam 102, a segmental beam reinforcement cage 104 hoisted on the traveling crane 103, and a reserved hole 105 opened inside the segmental beam reinforcement cage 104; a traveling frame 200 movably mounted on the traveling beam 102, an adjusting structure mounted on the traveling frame 200, and an internal sliding mechanism within the traveling frame 200. A U-shaped slide 300 is installed, and a lifting structure is installed on the U-shaped slide 300. A connecting slide 400 is installed on the lifting structure, and a positioning structure is installed on the connecting slide 400. After the segmental beam steel cage 104 is lifted above the assembly template 106 by the traveling crane 103, the positioning structure can be inserted into the reserved hole 105 by the adjustment structure and pressed against the inner wall of the reserved hole 105 to position the segmental beam steel cage 104 and prevent it from shaking when descending. Furthermore, the lifting structure allows the positioning structure to be adjusted to follow the height changes of the segmental beam steel cage 104.

[0024] Furthermore, the adjustment structure includes a dual-axis motor 201, which is mounted on the traveling frame 200. Each of the two output ends of the dual-axis motor 201 is equipped with a pulley 202, which is rotatably mounted inside the dual-axis motor 201. Both pulleys 202 are movably mounted on the traveling beam 102. When the dual-axis motor 201 is turned on, it can drive the pulleys 202 to rotate. The rotating pulleys 202 can roll on the traveling beam 102, thereby driving the traveling frame 200 to move on the traveling beam 102.

[0025] Furthermore, the lifting structure includes a drive motor 301, which is mounted above the U-shaped slide 300. A lead screw 302 is mounted on the output end of the drive motor 301, and a threaded sleeve 303 is threaded onto the lead screw 302. The threaded sleeve 303 is installed inside the traveling frame 200. An L-shaped support plate 304 is mounted on one end of the U-shaped slide 300. The lead screw 302 is rotatably mounted inside the U-shaped slide 300 and the L-shaped support plate 304. Two support diagonal rods 305 are mounted on the L-shaped support plate 304. The output end of the drive motor 301 can drive the lead screw 302 to rotate. The rotating lead screw 302 can be raised and lowered through the threaded engagement with the threaded sleeve 303, thereby driving the L-shaped support plate 304 and the connecting guide rod 400 to rise and fall.

[0026] Furthermore, the walking frame 200 has two guide holes 306 inside, and the U-shaped slide 300 is slidably installed in the two guide holes 306. When the lead screw 302 rotates, it can drive the U-shaped slide 300 to slide vertically in the guide holes 306.

[0027] Furthermore, the positioning structure includes a slide 401, which is slidably installed inside the connecting slide 400. The connecting slide 400 is installed on one side of the L-shaped support plate 304. Two connecting rods 402 are rotatably mounted on one side of the slide 401. A connecting seat 403 is rotatably mounted on each of the two connecting rods 402. A connecting rod 404 is rotatably mounted on each of the two connecting seats 403. One end of each connecting rod 404 is rotatably mounted on the connecting slide 400. A positioning pressure plate 405 is installed on one side of each of the two connecting seats 403. An auxiliary motor 406 is installed on one side of the L-shaped support plate 304. An adjusting screw 407 is installed at the output end of 6. The adjusting screw 407 is rotatably installed inside the L-shaped support plate 304 and the connecting slide 400. The slide 401 is threaded onto the adjusting screw 407. The auxiliary motor 406 is turned on to drive the adjusting screw 407 to rotate. When the adjusting screw 407 rotates, it can drive the slide 401 to move. The moving slide 401 will push the connecting seat 403 to move through 402, so that the connecting seats 403 on both sides drive the two positioning pressure plates 405 to move away from each other, so that the two positioning pressure plates 405 press on the inner walls of the two sides of the reserved hole 105 respectively, and position the segmental beam reinforcement cage 104.

[0028] Furthermore, the slide block 401 has a threaded hole 408 inside, and the adjusting screw 407 is threadedly installed in the threaded hole 408. When the adjusting screw 407 rotates, it can drive the slide block 401 to move through the threaded engagement with the threaded hole 408.

[0029] Furthermore, the connecting slide 400 has a guide slide hole 409 inside, and the slide block 401 is slidably installed in the guide slide hole 409. The moving slide block 401 will slide in the guide slide hole 409 on the connecting guide rod 400, thereby restricting the movement direction of the slide block 401.

[0030] The working principle is as follows: Before construction, the steel reinforcement binding and prestressed ducts of the segmental beam are prefabricated in the factory. A BIM model of the continuous beam segmental steel reinforcement binding and prestressed ducts is established to guide the factory fabrication, forming the segmental beam steel reinforcement cage 104. After being transported to the construction site, it is assembled using the segmental beam steel reinforcement cage splicing device of this invention. The conveying trolley 101 moves the segmental beam steel reinforcement cage 104 to the end of the segmental beam 100, and the traveling crane 103 lifts the segmental beam steel reinforcement cage 104 above the assembly template 106, so that the reserved holes 105 on the segmental beam steel reinforcement cage 104 correspond to the connecting guide rods 400. At this point, the dual-axis motor 201 can be turned on. The pulley 202 rotates, causing it to roll on the traveling beam 102. This movement of the traveling frame 200 on the traveling beam 102 causes the traveling frame 200 to move. The movement of the traveling frame 200 causes the U-shaped carriage 300 and the L-shaped support plate 304 to move, which in turn causes the connecting guide rod 400 to move into the reserved hole 105. At this time, the auxiliary motor 406 is turned on to drive the adjusting screw 407 to rotate. When the adjusting screw 407 rotates, it can drive the slide 401 to move through the threaded engagement with the threaded hole 408. The moving slide 401 slides in the guide hole 409 on the connecting guide rod 400, thus restricting the direction of movement of the slide 401. The continuously moving slide 401 can push the two sides One end of connecting rod 402 moves and rotates, causing the other end of connecting rod 402 to rotate on connecting seat 403. Simultaneously, this pushes connecting seat 403 to move. As connecting seat 403 moves, it is influenced by connecting rod 404 and moves away from connecting guide rod 400. During this process, connecting rod 404 rotates on connecting guide rod 400 and connecting seat 403 to adapt to the positional changes of connecting seat 403. This allows the two connecting seats 403 to move the two positioning plates 405 away from each other, causing the two positioning plates 405 to press against the inner walls of the reserved holes 105 on both sides, positioning the segmental beam reinforcement cage 104 and preventing it from swaying due to wind during hoisting. The segmental beam reinforcement cage 104 is positioned to ensure it is aligned with the top of the assembly template 106. Then, the traveling crane 103 lowers the segmental beam reinforcement cage 104 into the assembly template 106. During this process, the drive motor 301 can be turned on. The output end of the drive motor 301 can drive the lead screw 302 to rotate. The rotating lead screw 302 can be lowered through the threaded engagement with the threaded sleeve 303, thereby causing the lead screw 302 to drive the U-shaped slide 300 to slide vertically in the guide hole 306, which in turn drives the L-shaped support plate 304 and the connecting guide rod 400 to descend, so that the positioning pressure plate 405 can follow the segmental beam reinforcement cage 104 to descend, ensuring the stability of the segmental beam reinforcement cage 104 during the descent process.
