Electromagnetic geomembrane welding device

Abstract

The invention discloses an electromagnetic geomembrane welding device. The electromagnetic geomembrane welding device comprises an upper walking mechanism and a lower walking mechanism. The upper walking mechanism comprises an upper plate. A lower plane of the upper plate is provided with a driving wheel, a controller for controlling a walking direction, a vortex heater, and a magnetic component.The lower walking mechanism comprises a lower plate. An upper plane of the lower plate is provided with a magnetic component fitting component corresponding to the magnetic component. The upper planeof the lower plate is provided with a lower heater corresponding to the vortex heater. A distance between the magnetic component and the magnetic component fitting component is very small in a workingprocess, and an attraction force completely meets requirements of driving and clamping. A cross rod is made of metal with good heat conductivity, and a position in which the cross rod contacts with ageomembrane adopts a circular head or a roller with a smaller frication force. Under the action of a spring, a pressure of a vortex heater spring to a heating head is cooperated, so an overlapping layer of the geomembrane is extruded. In spite of heat melting welding or gluing pressure welding, the connection of the overlapping layer of the geomembrane can be tighter through a larger extruding force, and a water leakage situation does not occur.

Description

technical field [0001] The invention relates to the field of geomembrane laying equipment, in particular to high-efficiency electromagnetic geomembrane welding equipment without an open flame. Background technique [0002] Geomembrane is widely used in the engineering field of leakage prevention, especially in the solid waste disposal process, it is widely used in anti-seepage of landfills, anti-seepage of tailings reservoir areas, and anti-seepage of high-salt water drying ponds, etc. project. When the geomembrane is used in a large area, it is necessary to connect the geomembrane. Most of the current connection equipment is hot-melt welding and adhesive connection. It is difficult to compact the connection between the two membrane surfaces, causing the connection to be disconnected and affecting the construction quality.

Problems solved by technology

When the geomembrane is used in a large area, it is necessary to connect the geomembrane. Most of the current connection equipment is hot-melt welding and adhesive connection. It is difficult to compact the junction of the two membrane surfaces, causing the junction to be disconnected and affecting the construction quality

[0003] Moreover, the welding equipment for two geomembranes with a large overlapping area cannot be extended under the geomembrane for supporting clamping. If only hot-melt or adhesive crimping is performed on the top, the crimping will not be true due to the uneven ground of the geomembrane. It is prone to water leakage, and now we need a device that can be crimped up and down and can move freely according to the electric control, and can be welded or glued and then crimped
