Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically an automatic traveling hanging basket for bridge construction. Background Technology

[0002] The hanging basket is a core specialized piece of equipment for cantilever bridge construction. It is suspended from the completed beam segments through an anchoring system, providing a working platform and load-bearing support for the subsequent reinforcement binding, formwork installation and concrete pouring of the beam segments. As a key piece of equipment for high-altitude operations, it directly affects the accuracy, efficiency and safety of bridge construction, and is widely used in cantilever construction scenarios of structures such as long-span continuous beams and rigid frame bridges.

[0003] Automatic traveling formwork is a core specialized piece of equipment for bridge cantilever construction. It is typically suspended below a poured beam segment and moves forward along a guide rail using its own traveling system to achieve segmented pouring of the beam. Its main body consists of a load-bearing truss, formwork system, traveling mechanism, and anchoring device. It can bear the concrete pouring load and ensure construction accuracy, making it suitable for the high-altitude operation requirements of large-span bridges.

[0004] Currently, when the main body of the automatic walking basket is lifted by the hydraulic cylinder and moved on the pre-laid guide rail by the pushing device, the wind speed will increase significantly due to the high altitude. This will cause the basket to be subjected to strong lateral wind loads. Under the influence of the airflow, the wind will blow towards the sliding part between the main body and the guide rail, causing the basket to sway when it moves, which may cause danger.

[0005] Therefore, an automatic traveling formwork for bridge construction is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An automatic traveling basket for bridge construction, comprising a bridge base, on which a basket body is mounted; multiple fixing blocks are fixedly connected to the surface of the bridge base; the fixing blocks are located on both sides of the basket body; a motor is fixedly connected to the side wall of each fixing block; a threaded rod is fixedly connected to the output end of the motor; the threaded rod is rotatably connected to the fixing block; a first wind deflector is threaded onto the threaded rod; thereby, the first wind deflector blocks the airflow, preventing it from blowing towards the sliding point between the basket body and the guide rail, thus avoiding the basket body from swaying due to the airflow and causing danger; the movable nature of the first wind deflector ensures protection during the movement of the basket body.

[0008] Preferably, a pair of square holes are provided on the surface of the first wind deflector; a louvered air guide fan is fixedly connected in the square hole; multiple louvered air guide fans are provided; the louvered air guide fans are inclined; thus, the louvered air guide fans can guide the airflow smoothly through, avoid frontal hard impact, greatly reduce the wind load on the first wind deflector, and reduce the risk of deformation.

[0009] Preferably, a wind baffle is fixed to the inner side of the first wind deflector; the wind baffle is located inside the square hole; the surface of the wind baffle has multiple holes; thereby the wind baffle and the holes further reduce the impact force of the airflow, allowing the airflow to pass through in a smoother state.

[0010] Preferably, a second wind deflector is fixedly connected to the end of the first wind deflector; the second wind deflector is located on both sides of the main body of the hanging basket; thus, the second wind deflector blocks the airflow above the first wind deflector, further reducing the impact on the main body of the hanging basket and its bottom guide rail.

[0011] Preferably, a wind vane is provided on the bridge base; the wind vane is located in the middle of the bridge base; thus, the wind direction and strength of the airflow can be directly determined through the wind vane.

[0012] Preferably, a ribbon is fixed to the wind vane; the ribbon is located on one side of the wind vane; thus, the ribbon can more clearly indicate the direction of airflow and reduce the judgment error of relying solely on the wind vane.

[0013] The advantages of this utility model are:

[0014] 1. The automatic traveling basket for bridge construction described in this utility model has a first wind deflector that blocks the airflow, preventing the airflow from blowing towards the sliding part between the basket body and the guide rail, thereby avoiding the danger caused by the swaying of the basket body due to the influence of the airflow.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an automatic traveling basket for bridge construction includes a bridge base 1, on which a basket body 101 is mounted; multiple fixing blocks 102 are fixedly connected to the surface of the bridge base 1; the fixing blocks 102 are located on both sides of the basket body 101; a motor 103 is fixedly connected to the side wall of the fixing block 102; a threaded rod 104 is fixedly connected to the output end of the motor 103; the threaded rod 104 is rotatably connected to the fixing block 102; a first windbreak plate 105 is threadedly connected to the threaded rod 104; during operation, after completing the construction work on the bridge ahead, when it is necessary to move the basket body 101 forward, the basket body 101 is first lifted by a hydraulic cylinder, then a pushing device is installed on the guide rail at the bottom of the body, and the pushing device is started to drive the basket body 101 forward. At this time, the fixing blocks 102 on both sides are installed, and then the motors 103 on both sides are started. 03. The motor 103 drives the threaded rod 104 at its output end to rotate within the fixed block 102. When the threaded rod 104 rotates, the first baffle plate 105 on the threaded rod 104 moves with the rotation of the threaded rod 104. Thus, when the pushing device pushes the hanging basket body 101 forward, the first baffle plates 105 on both sides also move synchronously with the hanging basket body 101. Therefore, when the hanging basket body 101 moves, if airflow blows towards the sliding part between the hanging basket body 101 and the guide rail, the first baffle plate 105 can provide wind protection and prevent the airflow from causing swaying. Thus, the first baffle plate 105 blocks the airflow, preventing the airflow from blowing towards the sliding part between the hanging basket body 101 and the guide rail, thereby avoiding the danger caused by the swaying of the hanging basket body 101 due to the influence of airflow. The movable nature of the first baffle plate 105 ensures protection when the hanging basket body 101 moves.

[0026] like Figures 1 to 5 As shown, a pair of square holes 2 are provided on the surface of the first wind deflector 105; a louvered guide fan 201 is fixedly connected in the square hole 2; multiple louvered guide fans 201 are provided; the louvered guide fans 201 are inclined; during operation, when airflow blows towards the surface of the first wind deflector 105, the airflow will pass through the square holes 2 provided on the surface of the first wind deflector 105, and multiple louvered guide fans 201 are provided in the square holes 2. The airflow will be guided by the inclination of the louvered guide fans 201, so that after the airflow passes through the louvered guide fans 201, it will blow towards both sides of the hanging basket body 101, thereby avoiding the airflow directly impacting the first wind deflector 105; thus, the louvered guide fans 201 can directionally guide the airflow to pass smoothly, avoid direct hard impact, greatly reduce the wind load borne by the first wind deflector 105, and reduce the risk of deformation.

[0027] like Figures 1 to 5As shown, a baffle plate 3 is fixedly connected to the inner side of the first baffle plate 105; the baffle plate 3 is located inside the square hole 2; the surface of the baffle plate 3 is provided with multiple holes 301; during operation, after the airflow passes through the louvered guide fan 201 in the square hole 2 and is guided, it will be blocked by the baffle plate 3 on the inner wall of the louvered guide fan 201, and finally blow out from the holes 301 on the surface of the baffle plate 3. After the louvered guide fan 201 guides the airflow and reduces part of the impact force of the airflow, the direct impact force of the airflow is further weakened by the baffle plate 3 and the holes 301; thus, the baffle plate 3 and the holes 301 further reduce the impact force of the airflow, allowing the airflow to pass through in a smoother state.

[0028] like Figures 1 to 5 As shown, a second wind deflector 4 is fixedly connected to the end of the first wind deflector 105; the second wind deflector 4 is located on both sides of the main body 101 of the hanging basket; during operation, airflow will blow from above the first wind deflector 105 to the inside of the guide rail, at which time the second wind deflector 4 above the first wind deflector 105 will block this airflow, preventing it from blowing from above the first wind deflector 105 to the guide rail at the bottom of the main body 101 of the hanging basket; thus, the second wind deflector 4 blocks the airflow above the first wind deflector 105, further reducing the impact on the main body 101 of the hanging basket and its bottom guide rail.

[0029] like Figures 1 to 2 As shown, a wind vane 5 is installed on the bridge base 1; the wind vane 5 is located in the middle of the bridge base 1; when working, the wind vane 5 will be blown by the airflow and shake, so that the direction of the current dominant airflow can be intuitively fed back by observing the wind vane 5, and the strength of the airflow can also be known; thus, the wind direction and strength of the airflow can be intuitively known through the wind vane 5.

[0030] like Figures 1 to 2 As shown, a ribbon 6 is fixed to the wind vane 5; the ribbon 6 is located on one side of the wind vane 5; during operation, the ribbon 6 can assist in the observation of the wind vane 5. By observing the wind vane 5 and observing the direction and dynamic changes of the ribbon 6, further assistance can be provided in the judgment based on the observation of the wind vane 5; thus, the ribbon 6 can more clearly confirm the direction of the airflow and reduce the judgment error of relying solely on the wind vane 5.

[0031] Working principle: After completing the construction work on the bridge ahead, when it is necessary to move the main body 101 of the hanging basket forward, the main body 101 is first lifted by the hydraulic cylinder. Then, the pushing device is installed on the guide rail at the bottom of the main body, and the pushing device is started to drive the main body 101 forward. At this time, the fixing blocks 102 on both sides are installed, and the motors 103 on both sides are started. The motors 103 will drive the threaded rods 104 at their output ends to rotate within the fixing blocks 102. When the threaded rods 104 rotate, the first wind deflector 105 on the threaded rods 104 will rotate with the threaded rods 104. As the basket body 101 moves forward, the first wind deflectors 105 on both sides also move synchronously with it. When the basket body 101 moves, and airflow blows towards the sliding part between the basket body 101 and the guide rail, the first wind deflectors 105 provide wind protection, preventing the airflow from causing swaying. When airflow hits the surface of the first wind deflector 105, it passes through the square holes 2 on the surface of the first wind deflector 105. Multiple louvered guide fans 201 are installed inside the square holes 2, and the airflow follows the louvered guide fans 201. The tilt of 01 guides the airflow, causing it to blow towards both sides of the main body 101 of the hanging basket after passing through the louvered guide fan 201, thus preventing the airflow from directly impacting the first wind deflector 105. After the airflow is guided by the louvered guide fan 201 inside the square hole 2, it is blocked by the wind deflector 3 on the inner wall of the louvered guide fan 201, and finally blown out from the hole 301 on the surface of the wind deflector 3. After the louvered guide fan 201 guides the airflow and reduces some of the impact force, the wind deflector 3 and the hole 301 further reduce the direct impact force of the airflow. The airflow will then flow from the first... The airflow blows from above the first wind deflector 105 onto the inner side of the guide rail. At this time, the second wind deflector 4 above the first wind deflector 105 will block this airflow, preventing it from blowing from above the first wind deflector 105 onto the guide rail at the bottom of the hanging basket body 101. The wind vane 5 will sway due to the airflow, allowing for direct feedback on the direction of the prevailing airflow and its strength. The ribbon 6 can assist in observing the wind vane 5. By observing the wind vane 5 and observing the direction and dynamic changes of the ribbon 6, further assistance can be provided in judging the wind vane 5 based on the observation.
