Trackless trolley and construction method for transporting reinforcement mesh of face of rockfill dam

Abstract

The invention provides a trackless trolley and a construction method for transporting reinforcement mesh sheets of the face of a rockfill dam. The bottom of the trolley frame is provided with a plurality of walking tire devices, and the walking tire devices are connected to the trolley frame through a lifting mechanism; The bottom of the vehicle frame is also provided with a plurality of liftable hooks. The construction method includes the following steps: when the walking tire device of the trackless trolley transfers the steel mesh sheet on the post-casting block, the height of the trolley is adjusted to suit the construction site through the cooperation of the lifting mechanism and the liftable hook, and the liftable hook is hung Steel mesh, use the trolley to transport the steel mesh to the set position, after completing the layout of the current row of steel mesh, move the trackless trolley to other rows, and continue the above steps; realize the transfer of the steel mesh through the above steps . Through the set up and down walking tire device, it can adapt to the rapid installation, transfer, and quick installation and construction of steel mesh sheets with various thicknesses of panels in the construction of first pouring blocks and post-casting blocks.

Description

technical field [0001] The invention relates to the field of teaching devices, in particular to an interactive trigonometric function teaching device and method. Background technique [0002] The current knowledge inheritance is mostly based on the teaching method of books. Students read books combined with teacher's explanations to learn, which is inefficient, especially for boring mathematics, physics and chemistry knowledge. Low. At present, knowledge is growing at an unprecedented rate, so that human beings need to spend a lot of time on learning and consolidating knowledge. It takes at least 19 years to go from elementary school to doctorate. There are also teaching methods using audio-visual teaching in the prior art, but in actual work, audio-visual teaching is only used to play teaching materials such as ppt, and the interactive ability is not strong. One is that teachers, as non-professionals, lack the ability to write more interactive software; the other is that ...

[0003] Chinese patent document CN104809939A records a teaching aid for trigonometric functions, which has high interactivity and intuition, but the structure of the teaching aid is complex, and there are still deficiencies in intuition

Chinese patent document CN206505320U records a trigonometric function teaching device, the structure is relatively simple and intuitive, but the functional relationship that can be expressed by this scheme is still insufficient, especially the intuitive relationship between the triangle and each parameter and the relationship between the variation trends of each parameter Difficult to express directly
