Description

Technical Field

[0001] The utility model relates to the field of transport bearing devices, in particular to a transport bearing device for prefabrication of steel-concrete combined beams of bridges. Background Art

[0002] A steel-concrete composite beam of a bridge is a type of bridge structure that combines steel beams and concrete bridge decks through a specific connection method to bear joint loads. Steel beams are generally made of steel and have high strength and rigidity. Concrete bridge decks are usually cast from concrete, providing a bridge deck structure with strong compressive resistance. Steel-concrete composite beams have been widely used in modern bridge projects, such as highway bridges, railway bridges, urban viaducts, etc. A transport and load-bearing device is required during the prefabrication of steel-concrete composite beams of bridges. The current transport and load-bearing device for prefabrication of steel-concrete composite beams of bridges is inconvenient for buffering and protecting the steel-concrete composite beams of bridges. Therefore, a transport and load-bearing device for prefabrication of steel-concrete composite beams of bridges is needed.

[0003] The existing transport and carrying device for prefabricated steel-concrete composite beams of bridges is not convenient for buffering and protecting the steel-concrete composite beams of bridges during use. The rigid contact between the steel-concrete composite beams and the transport and carrying device will make the beam body itself vulnerable to damage, which may cause cracks in the concrete part, affecting its structural integrity and durability. In addition, it is not convenient to limit the steel-concrete composite beams of bridges by ropes, resulting in the displacement of the steel-concrete composite beams of bridges during transportation, and it is also inconvenient to install the traction columns. Therefore, a transport and carrying device for prefabricated steel-concrete composite beams of bridges is urgently needed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a transport and carrying device for prefabricated steel-concrete composite beams of bridges, so as to solve the problems that the existing transport and carrying device for prefabricated steel-concrete composite beams of bridges is inconvenient to provide buffering and protection for the steel-concrete composite beams of bridges, inconvenient to limit the steel-concrete composite beams of bridges by ropes, and inconvenient to install traction columns.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a transport and carrying device for prefabrication of steel-concrete composite beams of bridges, comprising a transport and carrying vehicle, the top of the transport and carrying vehicle is fixedly connected to a guide block, the inside of the guide block is movably connected to a slider, the outer wall of the slider is fixedly connected to a placement plate, and the bottom of the placement plate is fixedly connected to a damping spring.

[0006] The outer wall of the transport carrier is fixedly connected with a side block, a threaded hole is opened inside the side block, a threaded column is installed inside the side block, and a rope ring is fixedly connected to the top of the threaded column.

[0007] The outer wall of the transport carrier is fixedly connected with a frame plate, the interior of the frame plate is movably connected with a limit rod, the outer wall of the limit rod is fixedly connected with a clamping plate, and the outer wall of the limit rod is installed with a traction block.

[0008] Preferably, the guide block is of slotted design, and the guide block and the slider form a sliding structure.

[0009] Preferably, the number of the damping springs is set to two groups, and the damping springs are symmetrically arranged with respect to the central axis of the placement plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model provides a guide block, a slider, a placement plate, and a damping spring. By placing the bridge steel-concrete composite beam on the placement plate, the placement plate can be moved downward due to gravity, causing the slider to slide along the slide groove provided inside the guide block, driving the placement plate to squeeze the damping spring, thereby providing a buffering and protective effect for the bridge steel-concrete composite beam and preventing damage due to rigid contact between the steel-concrete composite beam and the transport bearing device.

[0016] 2. The utility model is provided with side blocks, threaded holes, threaded columns and rope rings. By moving the rope ring, the threaded columns are docked to the top of the side blocks and rotated, so that the threaded columns can be inserted into the threaded holes for positioning. The ropes are passed through the rope rings and tied to the steel-concrete composite beams of the bridge, which facilitates the rope winding and positioning of the steel-concrete composite beams of the bridge and prevents the steel-concrete composite beams of the bridge from deflecting and sliding during transportation.

[0017] 3. The utility model is provided with a transport carrier, a frame plate, a limit rod and a traction block. By pulling the limit rod, the limit rod can be slid along the frame plate, and the traction block is placed between the two frame plates.
