Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a hanging basket device for a cantilever arch bridge. Background Technology

[0002] A bridge formwork is a temporary supporting steel structure primarily used to bear the weight of concrete poured during cantilever construction. In bridge construction, especially in the cantilever casting of large-span prestressed concrete continuous beams (or continuous rigid beams), the formwork plays a crucial role. In the construction of cantilever arch bridges, the formwork is connected to the bridge deck. Load tests are required during construction to simulate actual construction loads and verify the formwork's load-bearing capacity under design loads. These tests verify whether the formwork structure meets design requirements, ensuring its safety and stability during construction.

[0003] In the existing technology, the hanging basket is connected to the bridge deck, anchor cables are installed in the bedrock, and jacks are welded to the hanging basket to connect with the anchor cables. The load change of the hanging basket is observed by pulling the anchor cables. In this method, only the bottom of the jack is fixed. Due to the uneven welding quality, the jack is prone to deviation during the pulling of the anchor cables, which not only affects the test data, but also makes it more troublesome to remove the jack later. Utility Model Content

One end of the top cover is provided with a protrusion, and the top cover is connected to one end of the support cylinder. The protrusion extends into the support cylinder and abuts against the jack.

[0009] Preferably, the top cover has an opening in the middle, and the shaft of the jack is connected to the opening and can extend out from the opening.

[0010] Preferably, the top cover is provided with a plurality of connecting holes I, and the support cylinder is provided with threaded grooves I.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1 , Figure 2 As shown, a cantilever arch bridge hanging basket device is provided. The hanging basket 4 includes several horizontal rails 41, several side rails 43, and a support beam 42. A support base plate 45 is provided between the horizontal rails 41. The support beam 42 is located in the middle of the horizontal rails 41. One end of the side rail 43 is connected to the horizontal rail 41, and the other end is connected to the support beam 42. The horizontal rails 41, side rails 43, and support beam 42 form a triangle. Several connecting rods 44 are provided between the side rails 43 and the horizontal rails 41. The several connecting rods 44 are connected in a triangle between the side rails 43 and the horizontal rails 41, which increases the overall stability of the hanging basket 4. As the bridge deck 2 is continuously constructed, the hanging basket 4 moves forward along the construction direction.

[0024] like Figure 1-4As shown, a load test assembly 5 is provided on the support base plate 45. The load test assembly 5 includes a support member and a jack installed inside the support member. The jack is a hollow hydraulic jack 6, which includes a kit 61 and a shaft 62. The kit 61 is hollow inside, and the shaft 62 is slidably connected inside the kit 61. The kit 61 is also hollow inside. Anchor cable 3 passes through the support member and is connected to the shaft 62 of the hollow hydraulic jack 6. The support member includes a support cylinder 51 and a top cover 52. The support cylinder 51 is hollow inside, and the hollow hydraulic jack 6 is connected inside the support cylinder 51. One end of the top cover 52 is provided with a protrusion 53, which is connected to one end of the support cylinder 51 and extends into the support cylinder 51. The jack abuts against the top cover 52. Because the hollow hydraulic jack 6 generates a large axial force during operation, the protrusion 53 increases the thickness of the top cover 52. This not only secures the hollow hydraulic jack 6 stably but also prevents the top cover 52 from being damaged due to the axial force of the hollow hydraulic jack 6. An opening 54 is provided in the middle of the top cover 52. The shaft 62 of the hollow hydraulic jack 6 is connected to the opening 54 and can extend from the opening 54. Several anchor cables 3 are connected to the shaft 62 and extend from the opening 54. When the shaft of the hollow hydraulic jack 6 pulls the anchor cables 3, the anchor cables 3 give the hanging basket 4 a reaction force. A sensor is set on the hanging basket 4 to detect the change value of the reaction force, thereby realizing the effect of detecting the load of the hanging basket 4.

[0025] like Figure 3 , Figure 4 As shown, the top cover 52 is provided with several connecting holes I 521, and the support cylinder 51 is provided with threaded grooves I 511. When the top cover 52 and the support cylinder 51 are connected, the connecting holes I 521 and the threaded grooves I 511 are aligned. Bolts 8 are detachably connected in the connecting holes I 521 and the threaded grooves I 511, and the bolts 8 fix the top cover 52 and the support cylinder 51. This ensures a stable connection while facilitating disassembly and assembly, greatly reducing the construction cycle and increasing the efficiency of testing. A base plate is provided at one end of the support cylinder 51. 7. The base plate 7 is fixed on the supporting base plate 45. A support 71 is provided on the base plate 7. Several connecting holes II 522 are provided on the top cover 52. The connecting holes II 522 are aligned with the support 71. The support 71 is provided with threaded grooves II 72. A screw 9 is detachably connected between the connecting holes II 522 and the threaded grooves II 72. The screw 9 further improves the connection stability between the top cover 52 and the supporting cylinder 51, so that the hollow hydraulic jack 6 remains stable during operation, thereby making the test results more accurate.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
