Problems solved by technology
[0003] However, when using a sling to fix the steel, the steel will often shake in the air due to the wind force, and the steel will often fall, which will eventually cause an accidental safety accident. Among them, the lifting rope can only move in one direction, and it is impossible to realize the simultaneous unloading of the upper end and the loading of the lower end, which reduces the transportation efficiency of the steel. Only when the ropes are disassembled can the cutting of the steel be realized, so that the transportation efficiency of the steel is further reduced

The present invention relates to the field of bridge engineering, in particular to a steel transportation device for bridge engineering construction, which includes a fixed base, a support frame, a lifting mechanism, a driving mechanism, a fixing mechanism, a linkage mechanism, a translation mechanism and a lifting slide. A support frame is fixedly connected to the middle position of the upper end, a support plate is fixedly connected to the rear side of the support frame, and two lifting slide plates are slidably connected to the front side of the support frame. Through the rotation of the active rotating shaft of the driving mechanism, the two threaded rods of the lifting mechanism can be driven to reverse the rotating shaft, so that the two lifting slides can slide in the front side of the support frame. An elevating slide plate is used for loading materials at the lower end, thereby avoiding the situation that the unloading at the upper end and the loading at the lower end cannot be carried out synchronously during the loading process using a sling, and the transportation efficiency of steel materials is improved.
Description
technical field [0001] The invention relates to the field of bridge engineering, in particular to a steel transportation device for bridge engineering construction. Background technique [0002] The steel transportation device for bridge engineering construction is a kind of construction transportation equipment used for transshipment of steel during bridge construction. Usually, the steel is fixed from a low place with a sling, and then lifted to a high place to unload it, so as to realize the need Use of steel for quick transfer. [0003] However, when using a sling to fix the steel, the steel will often shake in the air due to the wind force, and the steel will often fall, which will eventually cause an accidental safety accident. Among them, the sling can only move in one direction, and it is impossible to realize the simultaneous unloading of the upper end and the loading of the lower end, which reduces the transportation efficiency of the steel. At the same time, the ...
