Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a cast-in-place beam hanging basket balancing system. Background Art

[0002] The hanging basket is the main equipment in cantilever construction. It can be divided into four types according to the structural form: truss type, cable-stayed type, steel type and mixed type. When pouring a cantilever beam bridge with a larger span, the hanging basket method is used to perform segmented cantilever operations on site. It does not require the erection of brackets or the use of large cranes. Compared with other methods, the hanging basket construction has the advantages of light structure, simple and convenient assembly, and no pressure.

[0003] The construction of hanging basket is essentially to fix part of the hanging basket on the cantilever beam that has been solidified, hang the other part of the hanging basket outside the cantilever beam, and then lay steel bars and pour concrete in this part to form a new cantilever beam. After solidification, the position of the hanging basket is moved to start a new round of pouring. It can be seen that most of the structure of the hanging basket is fixed together, and the hanging basket is driven to move its position by a moving device (mainly hydraulic drive).

[0004] During the actual movement of the hanging basket, part of the structure of the hanging basket will gradually leave the support of the cantilever beam and be suspended in the air. Although the hanging basket is supported by the guide rail, due to the existence of the gap between the structures, the suspended part of the hanging basket will slightly tilt downward, making the height of the two ends of the hanging basket unbalanced. After stopping moving, the suspended part of the hanging basket needs to be lifted to make the heights of the two ends consistent before subsequent construction can be carried out. This will not only affect the construction quality, but also increase the construction steps and reduce construction efficiency. Utility Model Content

[0024] Embodiment

[0025] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 2 As shown in the figure, the cast-in-place beam hanging basket balance system of this embodiment includes a beam body 11, a hanging basket 12 provided at the end of the beam body 11, including a pair of main rods 13 horizontally arranged on the upper side of the hanging basket 12, a pair of slide rails arranged on both sides of the upper surface of the beam body 11, a first driving device arranged on the slide rails, a driving block 26 arranged at the end of the main rod 13 close to the slide rail, a balance block 31 arranged on the upper side of the main rod 13, and a second driving device for connecting the balance block 31 and the driving block 26; the first driving device is connected to the driving block 26. Specifically, when it is necessary to move the position of the hanging basket 12 for a new round of pouring after a single pouring is completed and solidified, before driving the first driving device, first use the second driving device to pull the balance block 31, and apply an upward acting force to a part of the hanging basket 12 away from the beam body 11 through the balance block 31. Then the first driving device drives the hanging basket 12 to move away from the beam body 11. During this process, a part of the hanging basket 12 gradually leaves the beam body 11 and has a tendency to tilt downward. However, due to the upward pulling effect of the second driving device on this part of the hanging basket 12, this tendency can be offset. In this way, not only can the hanging basket 12 always be in a horizontal state during the movement, but also the deformation of the hanging basket 12 can be effectively avoided, and the balance of the hanging basket 12 itself can be well ensured.

[0026] In this embodiment, there are a pair of first driving devices, and the pair of first driving devices are respectively connected to the pair of slide rails; one first driving device is connected to one driving block 26. Specifically, this can better reduce the burden on the first driving device and make the movement of the hanging basket 12 more stable.

[0027] The first driving device in this embodiment includes a first hydraulic cylinder 21, and a slide plate 22 provided on the side wall of the first hydraulic cylinder 21; the slide plate 22 is slidably provided in the slide rail. The slide plate 22 is provided with a plurality of first plug holes; the slide rail includes a bottom plate 23 detachably connected to the beam body 11, a U-shaped slide groove 24 provided on the bottom plate 23, and a second plug hole 25 provided on the slide groove 24; the first plug hole and the second plug hole 25 are connected by a latch. Specifically, the first hydraulic cylinder 21 performs linear motion on the beam body 11 through the cooperation of the slide groove 24 and the slide plate 22, wherein the bottom plate 23 is fixed to the beam body 11 by bolts, and the bottom plate 23 is spliced ​​from multiple pieces and can be disassembled and reused.

[0028] In this embodiment, the telescopic end of the first hydraulic cylinder 21 is hinged to the driving block 26. Specifically, the second driving device does not essentially pull the hanging basket 12 to produce a position, but only applies an upward force to the hanging basket 12. However, the hanging basket 12 itself will inevitably swing during the movement, so the hinge can prevent the swing of the hanging basket 12 from affecting the first hydraulic cylinder 21.

[0029] The second driving device in this embodiment includes a first connecting rod 32 for connecting a pair of driving blocks 26, a second connecting rod 33 for connecting a pair of balancing blocks 31, and a second hydraulic cylinder 36 hinged to the first connecting rod 32 and the second connecting rod 33. The second driving device also includes a support rod 35 hinged to one end of the driving block 26 close to the main rod 13, a second connecting rod 33 for connecting a pair of supporting rods 35, and a third connecting rod 34 hinged to the ends of the balancing block 31 and the second connecting rod 33; one end of the second hydraulic cylinder 36 is hinged to the second connecting rod 33, and the other end is hinged to the first connecting rod 32. Specifically, the support rod 35 plays a bridging role between the first connecting rod 32, the second connecting rod 33 and the third connecting rod 34, so that the force of the third connecting rod 34 on the balancing block 31 is obliquely upward, so that the balancing block 31 can be subjected to a larger upward component force.

[0030] The balance block 31 in this embodiment is disposed at the middle portion of the main rod 13 .

[0031] In summary, in the cast-in-place beam hanging basket balancing system of the present embodiment, when a single pouring is completed and solidified and the position of the hanging basket 12 needs to be moved for a new round of pouring, before driving the first driving device, the second driving device is first used to pull the balancing block 31, and the balancing block 31 applies an upward force to a part of the hanging basket 12 away from the beam body 11, and then the first driving device drives the hanging basket 12 to move away from the beam body 11. During this process, a part of the hanging basket 12 gradually leaves the beam body 11, and it has a tendency to tilt downward. Since the second driving device has an upward pulling effect on this part of the hanging basket 12, it can offset this tendency. This not only keeps the hanging basket 12 always horizontal during the movement process, but also effectively avoids deformation of the hanging basket 12, thereby ensuring the balance of the hanging basket 12 itself.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
