Description

Technical Field

[0001] The utility model belongs to the technical field of building production, and in particular relates to a steel cage transfer vehicle, which is suitable for preventing the steel cage from falling off the transfer vehicle. Background Art

[0002] Steel cage is a commonly used steel bar processing product in concrete structure. It is a cage-like structure formed by pre-tying multiple steel bars in a certain arrangement. It is used to enhance and strengthen the strength and bearing capacity of concrete. In bored pile construction, the steel cage is the part that bears the concrete injected into the pile body and is an important part of the pile foundation structure. In concrete structures, when the components are columnar or strip-shaped, steel bars are only arranged under the surface of the component that contacts the air. At this time, the steel cage is also pre-made as a structure for the steel bars around the components. The production and installation of steel cages is one of the important links in construction engineering, and plays a vital role in the structural safety and quality of buildings.

[0003] The traditional method is to manually transport the steel bars in the steel bar processing site and process them on-site. The dead weight of the steel cage after processing is large, and manual transportation is labor-intensive and inefficient. Therefore, it is necessary to develop a steel cage transfer vehicle to assist traction equipment in transporting and moving the steel cage. The invention patent with application number 202110012186.2 discloses a transfer and lifting device for long spiral bored pile steel cages, including a frame, a support frame, an axle and wheels. The axle is arranged at the bottom of the frame through a support frame, and the wheels are arranged at both ends of the axle. Limited position steel bars are arranged on the frame. When transporting the steel cage, one or two transfer and lifting devices are placed under the steel cage, and the excavator is connected to the front end of the steel cage through a traction rope to tow the steel cage to the construction site. Although the transfer device can reduce the handling intensity and improve the handling efficiency, the following problems still exist:

[0004] 1. The traction equipment is connected to the front end of the steel cage, and the steel cage is directly affected by the traction force of the traction equipment, which can easily cause the steel cage to move along the traction direction or even fall off the transfer vehicle.

[0005] 2. There is no connection device between the front and rear transfer vehicles. The forward power of the rear transfer vehicle only comes from the friction with the steel cage. The traction force on the rear transfer vehicle is insufficient, and it is easy to separate from the front transfer vehicle, making it difficult to correctly follow the forward direction of the front transfer vehicle.

[0006] 3. When the transfer vehicle is loading materials or bumping during the transfer process, it is easy to tilt due to unstable center of gravity, causing the front or rear end of the steel cage to warp, which requires manual straightening, otherwise the transfer cannot proceed smoothly.
