Description

Technical Field

[0001] This utility model relates to the field of arch flatbed cart technology, and more specifically, to a moving device for an arch flatbed cart for an externally enclosed arch bridge. Background Technology

[0002] The main arch of the upper-bearing, rigid-framed, concrete-encased arch bridge is divided into three main arch ribs laterally. The entire bridge comprises 69 segments and 50 crossbeams, interconnected to form a stable system. The concrete encasing construction sequence is: bottom slab → web → top slab. During bottom slab construction, each arch rib is divided into 10 large working faces, each further divided into 10 smaller working faces, each approximately 4.5 meters long. When tying the bottom slab reinforcement, a scaffold is installed on each bank of each rib for reinforcement tying. The scaffold consists of an arch-back flatcar and a suspended platform, connected by four 28mm steel cables and four 10-ton chain hoists. The lifting frame is moved as follows: two 28mm steel cables are fixed to the nodes of the two chord tubes at the top, and two 28mm steel cables are fixed to the nodes of the arch back flatcar at the bottom. Two 10-ton chain hoists are set between the upper and lower 28mm steel cables. The lifting frame is moved by manually pulling the 10-ton chain hoists on both sides.

[0003] The existing technology uses a 10-ton chain hoist to move the gantry, which is physically demanding for the operators and has low moving efficiency. Moving a single gantry takes up to 9 hours. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a moving device for the flatcar on the arch of an externally clad arch bridge. This device uses a drive component fixed to the chord tube to drive the flatcar on the arch, thereby reducing the physical exertion on the operators.

[0005] This utility model is achieved through the following technical solution: a moving device for the flatbed of an outer arch bridge, including a flatbed, with steel strands fixedly connected to both sides of the flatbed. It also includes two drive components, each of which is fixedly connected to a spreader beam. The spreader beam has holes for the steel strands to pass through. The drive components are used to pull the steel strands away from the flatcar at the top of the arch. The spreader beam is detachably connected to a U-shaped saddle clamp, which engages with the chord of the outer arch bridge.

[0006] Furthermore, the arch flatcar and the steel strand are fixedly connected by an anchoring extrusion head.

[0007] Furthermore, the arched flatcar includes an outer frame, within which reinforcing beams are fixedly connected.

[0008] Furthermore, a safety steel rope is fixedly connected to the bottom of the arched flatcar, and a suspended basket is fixedly connected to the end of the safety steel rope away from the arched flatcar.

[0009] Furthermore, it also includes a displacement detection box, which includes a box body with a magnetic suction component at the bottom. The box body has a cavity, a trigger switch on one side of the cavity, a stop block slidably connected inside the cavity, and an elastic component fixedly connected to the side of the cavity away from the trigger switch. The end of the elastic component near the trigger switch is fixedly connected to the stop block, and a rope is fixedly connected to the side of the stop block away from the trigger switch. The rope extends out of the box body, and the end of the rope away from the stop block is fixedly connected to a U-shaped saddle clip.

[0010] Furthermore, an indicator light and a buzzer are fixedly connected to the box, and the indicator light and buzzer are electrically connected to the trigger switch.

[0011] The technical solution of this utility model has at least the following beneficial effects: The arch-top flatcar is deployed on the arch of an outer arch bridge, serving as a mobile device to facilitate the transport of work materials. The drive mechanism replaces manual pulling of the arch-top flatcar by extending a steel cable away from it, thus reducing the physical exertion of the operators.

[0012] Since the driving direction is mostly from both sides of the arch towards the top of the middle section of the arch, the driving component should be positioned in the direction of the arch top flatcar towards the middle section of the arch. A spreader beam is fixed to the driving component, with holes for the steel strands to pass through. This constrains the position of the steel strands and, through cooperation with U-shaped clamps, forms a rigid connection with the chord of the outer arch bridge, thus creating a stable reaction structure. When driving the steel strands, the reverse force is transmitted to the chord. Since the chord, as the load-bearing frame of the bridge, has a very high load-bearing capacity, the U-shaped clamps rigidly connect the driving component to the chord, creating a support point in the direction of the middle section of the arch.

[0013] The steel strands and drive components are each equipped with two, so that the two sides of the arch flatcar are respectively subjected to the tension along the two chords of the outer arch bridge, making the force posture more stable and less prone to tilting due to uneven force.

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following detailed description illustrates the specific implementation method: Example 1: As attached Figures 1-7 As shown: A moving device for the flatbed of an outer arch bridge includes a flatbed 1. Steel strands 2 are fixedly connected to both sides of the flatbed 1 by anchoring compression heads 103. The anchoring compression heads 103 clamp the steel strands 2 after plastically deforming them.

[0020] It also includes two drive components 3, each a 24-ton single-pull jack. Each drive component 3 is bolted to a spreader beam 4, which has holes 5 for the steel strand 2 to pass through. The drive component 3 is used to pull the steel strand 2 away from the arch flatcar 1. The spreader beam 4 is detachably connected to a U-shaped saddle clamp 6, which engages with the chord tube 8 of the outer arch bridge 7.

[0021] The arched flatcar 1 includes an outer frame 101, and a reinforcing beam 102 is welded and fixed inside the outer frame 101. A safety steel rope 9 is fixedly connected to the bottom of the arched flatcar 1, and a suspended basket 10 is fixedly connected to the end of the safety steel rope 9 away from the arched flatcar 1.

[0022] The arch-top flatcar 1 is deployed on the arch of the outer arch bridge 7, serving as a mobile device extending the arch to facilitate the transport of work materials. The outer frame 101 increases the structural strength of the arch-top flatcar 1, and the reinforcing beams 102, including cross beams and prismatic beams, reduce the probability of structural deformation due to excessive load. A safety steel rope 9 connects to a suspended basket 10, which transports work materials. Operators can place work materials in the basket 10 and drive the arch-top flatcar 1, thereby moving the basket 10.

[0023] The drive unit 3 is used to replace manual pulling of the arch flatcar 1. It pulls the arch flatcar 1 by pulling the steel strand 2 away from the arch flatcar 1, thereby reducing the physical exertion of the operator.

[0024] Since the driving direction is mostly from the sides of the bridge arch towards the top of the middle section of the arch, the position of the driving component 3 should be in the direction of the arch top flatcar 1 towards the middle section of the arch. A spreader beam 4 is fixed to the driving component 3, with holes 5 for the steel strands 2 to pass through. This constrains the position of the steel strands 2 and, through cooperation with U-shaped saddle clamps 6, forms a rigid connection with the chord tubes 8 of the outer arch bridge 7, thus forming a stable reaction structure. When driving the steel strands 2, the reverse force is transmitted to the chord tubes 8. Since the chord tubes 8 serve as the load-bearing frame of the bridge structure, they have a large load-bearing capacity. The rigid connection between the driving component 3 and the chord tubes 8 via the U-shaped saddle clamps 6 creates a force support point located in the middle section of the arch. Two steel strands 2 and two driving components 3 are configured, deployed on both sides of the bridge structure, so that the arch top flatcar 1 is subjected to tension along the chord tubes 8 on both sides of the outer arch bridge 7, resulting in a more stable force posture and preventing tilting due to uneven force distribution.

[0025] Compared to existing technologies, conventional manual traction takes 9 hours, while using a cable hoisting system occupies critical equipment. This embodiment is more efficient, completing the same task in just 3 hours without occupying a cable hoisting system, increasing efficiency by 200%, significantly reducing manual input and labor intensity, freeing up critical equipment resources, and improving equipment turnover rate.

[0026] Example 2: The difference from the above embodiment is that it also includes a displacement detection box 11. The displacement detection box 11 includes a box body 1101. A magnetic suction element 1102 is provided at the bottom of the box body 1101. The magnetic suction element 1102 is a magnet. The attraction force of the magnetic suction element 1102 is greater than the force threshold required for the rope 1107 to break. A cavity 1103 is provided inside the box body 1101. A trigger switch 1104 is installed on one side of the cavity 1103. A stop block 1105 is slidably connected inside the cavity 1103. An elastic element 1106 is welded and fixed to the side of the cavity 1103 away from the trigger switch 1104. The end of the elastic element 1106 near the trigger switch 1104 is welded and fixed to the stop block 1105. A rope 1107 is bonded and fixed to the side of the stop block 1105 away from the trigger switch 1104. The rope 1107 extends out of the box body 1101. The end of the rope 1107 away from the stop block 1105 is bonded and fixed to a U-shaped saddle clip 6.

[0027] An indicator light 1108 and a buzzer 1109 are bolted to the housing 1101. The indicator light 1108 and the buzzer 1109 are electrically connected to the trigger switch 1104.

[0028] When the driving component 3 pulls the steel strand 2, the string tube 8 will experience a reaction force. If the U-shaped saddle clip 6 is not secured tightly enough, the spreader beam 4 and the driving component 3 will slip, creating a safety hazard. The box body 1101 can be attached to the string tube 8 by the magnetic component 1102. During initial deployment, the rope 1107 is straightened, causing the abutment block 1105 to be pulled by the rope 1107, pressing the elastic component 1106. If the U-shaped saddle clip 6 does not slip, the force on the rope 1107 will remain unchanged. If the U-shaped saddle clip 6 slips, the rope 1107 will continue to pull the stop block 1105, causing the stop block 1105 to continue pressing the elastic element 1106. As the elastic element 1106 is continuously compressed, the elastic force it generates increases. When the sliding distance of the U-shaped saddle clip 6 exceeds a certain value, the elastic force of the elastic element 1106 will exceed the force threshold required for the rope 1107 to break. The rope 1107 will break, and the elastic element 1106 will push the stop block 1105 out, causing the stop block 1105 to press the trigger switch 1104. After the trigger switch 1104 is pressed, the indicator light 1108 and the buzzer 1109 will activate, prompting the operator to promptly check and maintain the fixing relationship between the U-shaped saddle clip 6 and the string tube 8.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
