Description

Technical Field

[0001] This utility model belongs to the field of cast-in-place technology for large-span beams, specifically relating to a new hydraulic walking-type ultra-large segment hanging basket traveling system. Background Technology

[0002] With the continuous advancement of construction technology, the design span of bridges is gradually increasing. The hanging basket construction process is suitable for long-span bridges. The hanging basket is a mobile scaffold that can move along a track, suspended from the already constructed box girder segment. The rear end of the hanging basket is fixed to the box girder segment by a rear anchor. By moving the hanging basket, the formwork, reinforcing bars, and pipes for the next segment can be erected, concrete poured, and prestressed tensioning and grouting operations can be performed.

[0003] The existing construction formwork requires the removal of the rear anchor before it can move along the track, allowing the formwork to tilt freely forward and the rear hook wheel on the formwork to hook onto the track. After installing an anti-overturning device, the formwork can move. However, during this construction process, the anti-overturning device is not installed when the rear anchor is removed, and the rear hook wheel of the formwork is prone to detaching from the track, which is not conducive to safe construction. Furthermore, when the formwork moves, relative sliding occurs between the formwork and the track, and the sliding friction between the two is relatively large, which can easily cause wear on the track and the formwork, and is also not conducive to saving energy.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figure 1 The present invention provides a novel hydraulic walking-type ultra-large segment hanging basket traveling system. The system includes a traveling track 10, a main beam 20, a traveling mechanism 30, and at least two sets of hydraulic lifting components 40. The traveling track 10 is mounted on the upper surface of the box girder 60. The main beam 20 is located above the traveling track 10, with a first anti-locking wheel 21 at one end, which rolls upward against the traveling track 10. A groove 22 is provided on the side wall of the main beam 20. The traveling mechanism 30 is slidably connected above the traveling track 10 and abuts upward against and supports the main beam 20. A second anti-locking wheel 331 is provided on the traveling mechanism 30, which extends into the groove 22 and rolls downward against the groove wall. At least two sets of hydraulic lifting components 40 are horizontally spaced and vertically mounted on the box girder 60. The output end of each hydraulic lifting component 40 is connected to the main beam 20 to support it.

[0025] It should be noted that the traveling track 10 can be I-shaped. The first anti-rolling wheel 21 can form an upward rolling state in the side groove of the traveling track 10. The first anti-rolling wheel 21 is used to balance the overturning moment of the main beam 20 in the traveling state. One first anti-rolling wheel 21 is provided on each side of the main beam 20, which can be anti-rolled onto the traveling track 10. The traveling mechanism 30 is located between the traveling track 10 and the main beam 20 and supports one side of the main beam 20. The traveling mechanism 30 has a second anti-rolling wheel 331, which can be anti-rolled into the groove 22 on the main beam 20. The first anti-rolling wheel 21 and the second anti-rolling wheel 331 can prevent the main beam 20 from overturning. The excessive forward tilting disengages the main beam 20 from the travel track 10, which in turn improves the connection strength between the main beam 20 and the travel track 10. It can also replace the sliding fit with a rolling fit, which can reduce the wear between the main beam 20 and the travel track 10 and reduce the external force applied when the main beam 20 moves, thus increasing construction safety. The hydraulic lifting component 40 can lift the main beam 20 and reduce the pressure of the main beam 20 on the travel mechanism 30, so that the travel mechanism 30 can move first, and the main beam 20 can follow the travel mechanism 30 to move in the next step. This can accurately push the main beam 20 to the predetermined fixed position and improve construction efficiency.

[0026] The beneficial effects of the hydraulic walking type ultra-large segment hanging basket traveling system provided by this utility model are as follows: Compared with the prior art, the main beam 20 of this utility model is provided with a first anti-locking wheel 21 and a sliding groove 22, and the traveling mechanism 30 slidably set on the traveling track 10 is provided with a second anti-locking wheel 331. The first anti-locking wheel 21 rolls against the traveling track 10 and is locked onto the traveling track 10 to prevent the main beam 20 from leaving the traveling track 10; the second anti-locking wheel 331 slides with the sliding groove 22 and can abut against the sliding groove 22. The first buckle wheel 21 abuts against the travel track 10, and the second buckle wheel 331 abuts against the inner wall of the slide groove 22. They can cooperate to increase the connection strength between the main beam 20 and the travel track 10, prevent the main beam 20 from detaching from the travel track 10, prevent the hanging basket from falling, and improve construction safety. The rolling cooperation of the first buckle wheel 21 and the second buckle wheel 331 can reduce the sliding friction between the main beam 20 and the travel track 10. When moving the hanging basket, it can reduce the sliding wear between the travel track 10 and the main beam 20, and save power and energy.

[0027] In one possible implementation, please refer to Figures 1 to 3 The side wall of the traveling track 10 is provided with a first limiting groove 11; wherein, the first reverse buckle wheel 21 is located in the first limiting groove 11 and rolls upward against the upper groove wall of the first limiting groove 11.

[0028] It should be noted that the first limiting groove 11 can be a concave groove. When the main beam 20 travels on the travel track 10, the side of the main beam 20 away from the first reverse wheel 21 is suspended. One end of the suspended main beam 20 drives the first reverse wheel 21 to move upward. The first reverse wheel 21 rolls against the upper groove wall of the first limiting groove 11 and is limited by the limiting groove, preventing the first reverse wheel 21 from sliding upward out of the first limiting groove 11, so that the main beam 20 and the travel track 10 are connected.

[0029] In one possible implementation, please refer to Figures 1 to 3 The bottom wall of the main beam 20 is provided with a limiting plate 23 protruding to both sides. A groove 22 is formed between the limiting plate 23 and the main beam 20. The second reverse wheel 331 rolls on the upper surface of the limiting plate 23.

[0030] It should be noted that the upper surface of the limiting plate 23 forms the inner wall of the sliding groove 22. When one end of the suspended main beam 20 drives the first anti-locking wheel 21 to move upward and roll against the inner wall of the first limiting groove 11, the second anti-locking wheel 331 abuts against the limiting plate 23 and is limited by the limiting plate 23, preventing the second anti-locking wheel 331 from detaching from the bottom wall of the main beam 20, increasing the connection strength between the main beam 20 and the traveling track 10, preventing the main beam 20 from derailing from the track, improving construction safety, and eliminating the need to install an additional anti-overturning device after removing the rear anchor, which simplifies the construction process.

[0031] In one possible implementation, please refer to Figures 1 to 3 The traveling mechanism 30 includes two traveling beams 31, a front support 32, and a rear support 33. The two traveling beams 31 are spaced apart and are slidably connected to the traveling track 10. The front support 32 is located on the traveling beam 31 away from the first reverse wheel 21, and a support wheel 321 is provided on the front support 32 for abutting against the bottom wall of the main beam 20. The rear support 33 is located on the traveling beam 31 close to the first reverse wheel 21, and a second reverse wheel 331 is provided on the rear support 33.

[0032] It should be noted that the traveling mechanism 30 includes two traveling beams 31 spaced apart and both slidingly engaged with the traveling track 10. A front support 32 and a rear support 33 are respectively mounted on the two traveling beams 31. The front support 32 abuts against the bottom wall of the main beam 20 via a support wheel 321, which reduces the sliding friction between the support wheel 321 and the main beam 20 during travel, thus reducing wear on the main beam 20. When the main beam 20 is traveling, the front support 32 first travels within the traveling track 10, which changes the position of the support wheel 321 relative to the main beam 20. The support position of the bottom wall of the main beam 20 prevents the support position of the support wheel 321 from getting too close to the rear support 33 during the movement of the main beam 20, which would increase the overturning moment on the side of the main beam 20 away from the first anti-locking wheel 21 and increase the risk of the main beam 20 leaving the walking track 10; the alternating walking of the front support 32 and the main beam 20 is conducive to the smooth connection between the main beam 20 and the walking track 10; after the front support 32 moves to the designated position, the main beam 20 drives the rear support 33 to slide along the walking track 10.

[0033] In one possible implementation, please refer to Figure 2 The bottom of the traveling beam 31 is provided with a second limiting groove 311, and the two sides of the traveling track 10 are respectively slidably engaged with the two second limiting grooves 311.

[0034] It should be noted that the second limiting groove 311 can be a concave groove. While the second limiting groove 311 is slidably connected to the traveling track 10, the two sides of the traveling track 10 are respectively slidably embedded in the two second limiting grooves 311. This can limit the vertical displacement of the traveling beam 31 when it slides on the traveling track 10, and prevent the traveling beam 31 from detaching from the traveling track 10 when the main beam 20 tilts forward due to the second anti-locking wheel 331 locking the main beam 20. The fixed horizontal position of the traveling track can improve the connection strength between the main beam 20 and the traveling track 10 and improve construction safety.

[0035] In one possible implementation, please refer to Figure 2 The front support 32 is provided with a lower step 322, the support wheel 321 is located on the lower step 322, and a pad 323 is detachably connected to the front support 32, the pad 323 abuts against the lower surface of the main beam 20.

[0036] It should be noted that the front support 32 can adopt a stepped box structure welded from steel plates. The support wheel 321 is located on the first lower step 322 at the front end of the front support 32. The pad 323 between the support frame and the main beam 20 can be 30mm thick, which can serve as the bottom support of the main beam 20 when the main beam 20 is stationary. When the main beam 20 travels on the travel track 10, the pad 323 can be removed to allow the main beam 20 to move while supported on the support wheel 321.

[0037] In one possible implementation, please refer to Figure 4 The hydraulic jacking component 40 includes a jacking frame 41 and a hydraulic cylinder 42. The jacking frame 41 is mounted on the main beam 20, and one end of the hydraulic cylinder 42 is connected to the jacking frame 41, while the other end is connected to the box beam 60.

[0038] It should be noted that the lifting frame 41 can be an inverted U-shaped gantry composed of a crossbeam and outriggers, with the outriggers and crossbeam connected by high-strength bolts; the crossbeam is supported on the lower surface of the main beam 20, and the lower ends of the outriggers are supported on the top surface of the box girder 60 via hydraulic cylinders 42; the main beam 20 and the front support 32 move alternately within the traveling track 10, and the farthest distance that the front support 32 slides within the traveling track is the distance between the front support 32 and the lifting frame 41 when the main beam 20 is stationary. The alternating movement of the front support 32 and the main beam 20 allows... The front support 32 and the main beam 20 form a walking motion, which can accurately push the main beam 20 to the predetermined fixed position and improve construction efficiency. The number of lifting frames 41 can be one or two. When there is one lifting frame 41, the lifting frame 41 is located on the side of the front support 32 away from the rear support 33 and is spaced apart from the front support 32. When there are two lifting frames 41, the two lifting frames 41 are located on both sides of the front support 32 and are spaced apart from the front support 32.

[0039] In one possible implementation, please refer to Figure 1 Multiple cushions 12 are spaced apart below the travel track 10, with the cushions 12 below the end of the travel track 10 away from the first reverse wheel 21 being densely arranged.

[0040] It should be noted that the bolster 12 can support the traveling track 10, maintain the stability of the traveling track 10, and transmit the pressure of the main beam 20 on the traveling track 10; the bolster 12 is connected to the traveling track 10 through fasteners, playing the role of supporting the rail and ensuring the stability of the rail position; the bolster 12 can transmit the huge pressure of the main beam 20 to the box girder 60 in the future, preventing the traveling track 10 from sinking due to the pressure of the main beam 20; the bolster 12 can be made of rubber, and is densely installed below the end of the traveling track 10 away from the first anti-locking wheel 21, which can effectively reinforce the traveling track 10, prevent the traveling track 10 from deviating from the box girder 60, and effectively transmit the huge pressure from the main beam 20, protecting the traveling track 10.

[0041] In one possible implementation, please refer to Figure 5 There are multiple main beams 20, and each main beam 20 is distributed at intervals along a direction perpendicular to the travel track 10 and is connected by a connecting beam 50.

[0042] It should be noted that the movement of the main beam 20 on the traveling track 10 can rely on the traveling cylinder. The traveling cylinder can be a 60-ton engineering cylinder with a stroke of 1.0m. It is centrally controlled by a 30-channel intelligent synchronous control system of PLC to ensure that multiple main beams 20 move synchronously and prevent multiple main beams 20 from shifting laterally.

[0043] In one possible implementation, please refer to Figure 1 The end of the travel track 10 away from the first reverse wheel 21 is provided with a traction rod 13, which is connected to the main beam 20.

[0044] It should be noted that the main beam 20 is equipped with a traveling cylinder, which is connected to the traction rod 13. The traveling cylinder pulls the traction rod 13 and drives the main beam 20 to travel on the traveling track 10 through the pushing action of the traveling cylinder.

[0045] The working principle of the hydraulic walking type ultra-large segment hanging basket traveling system provided by this utility model is as follows: When the hanging basket needs to move forward, the rear anchor is removed from one end of the main beam 20. At this time, the middle part of the main beam 20 is supported by the support wheel 321 on the front support 32 and the other end moves downward, causing the main beam 20 to tilt so that the first anti-locking wheel 21 locks the traveling track 10. The pad 323 on the front support 32 is removed, so that the support wheel 321 is supported on the lower surface of the main beam 20. The second anti-locking wheel 331... The sliding groove 22 is reversed. At this time, the main beam 20 is raised in height by the hydraulic cylinder 42, and the front support 32 is controlled to slide within the traveling track 10 to the lifting frame 41. The hydraulic cylinder 42 causes the main beam 20 to press against the support wheel 321 again. The main beam 20 is moved by the traction rod 13. The front support 32 and the main beam 20 move alternately in a stepping manner. Finally, the main beam 20 moves to the predetermined position and is fixed to the top surface of the box girder 60 by the rear anchor, and concrete pouring is carried out.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
