A geogrid unwinding device and its working steps

Abstract

The invention discloses a geogrid unreeling device and an operation step thereof. The geogrid unreeling device comprises a device base, an unreeling drive mechanism, an ureeling frame, a lifting chuck, an upper device cover, a cutoff tool head, a grid outlet drive mechanism, a tensioning mechanism, a caterpillar drive mechanism, a horizontal movement device and a device casing. The length of geogrids can be controlled through arrangement of a cutting mechanism, the sampled geogrids meet the project requirements, besides, unnecessary waste is avoided, fewer geogrids are used, and the cost is reduced; by means of the caterpillar drive mechanism, the geogrid unreeling device can adapt to different environments; by adopting a motor for driving, labor is saved and the unreeling efficiency is higher; by additionally arranging a tensioning device, grids inside are prevented from loosening and twining around the geogrid unreeling device to result in damage to the device; the geogrid unreelingdevice has higher operation efficiency next time by means of the cutoff tool head with a lock seam; and the geogrid unreeling device not only can avoid unnecessary waste, reduce the number of the geogrids and reduce the cost, but also has high unreeling efficiency.

Description

technical field [0001] The invention belongs to the field of engineering equipment, relates to geogrid unwinding technology, and specifically relates to a geogrid unwinding device and working steps thereof. Background technique [0002] Geogrid is a major geosynthetic material, which has unique performance and efficacy compared with other geosynthetics. Commonly used as reinforcement for reinforced soil structures or reinforcement for composite materials, etc., geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. . The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of polypropylene, polyvinyl chloride and other polymers through thermoplastic or molded. When used as a civil engineering, it is called geotechnical grille. It has high strength, small deformation, small creep, corrosion resistance, long life, and is convenient for co...

AI Technical Summary

Problems solved by technology

It has high strength, small deformation, small creep, corrosion resistance, long life, and is convenient for construction and transportation. At present, the construction and transportation equipment of geogrids are relatively simple and backward, and most of them are transported by trucks and manually rolled up. , when some small construction sites need to be transported manually because trucks cannot reach them, this not only consumes manpower but also reduces the transport efficiency, and may also cause injuries to people during the process of manual transport. Therefore, a combination of transport and rolling Appearance of the device is imminent
