A paste filling support with the function of goaf support

Abstract

The invention discloses a paste filling support with the function of goaf support, which comprises a column, a base and a top beam. There are two hinged paste-filled support plates on the lower end of the roof beam. The front support plate is connected to the inner side of the lower end of the roof beam, and the rear support plate protrudes from the tail end of the roof beam and can rotate up and down. An upper isolation plate support is provided, and the rear support plate is fixedly connected with the upper isolation plate support. The telescopic arm of the first oil cylinder set between the upper isolation plate support and the top beam drives the upper isolation plate support to rotate, and then The shield also rotates thereupon. The telescopic arm of the second oil cylinder set between the upper isolation plate and the top beam pushes the upper isolation plate to rotate, and a backing plate and a lower isolation plate set outside the backing plate are arranged at the end of the base, and the upper and lower isolation plates are perpendicular to the base Lap on plane. The telescopic arm of the third oil cylinder arranged between the lower isolation plate and the backing plate pushes down the lower dividing plate to better isolate the paste in the filling process.

Description

technical field [0001] The invention relates to a paste filling bracket with the function of goaf support. Background technique [0002] Modern large-scale coal mining has caused land subsidence, and the mining of coal resources under buildings involves many problems such as relocation of villages and compensation, resulting in conflicts between workers and farmers. Paste filling mining can realize safe and efficient mining of compressed coal under buildings without relocating villages and reducing compensation. Use the filling support with support function to shorten support time, reduce support cost and increase filling capacity. However, there are many defects in the prior art: First, the support assembly is an integral structure, and the roof of the filling area is uneven. In order to adapt to the roof situation, the length of the support assembly needs to be shortened, and the filling step is limited, which affects the filling efficiency. Two, the support assembly is ...

Problems solved by technology

However, there are many defects in the prior art: First, the support assembly is an integral structure, and the roof of the filling area is uneven. In order to adapt to the roof situation, the length of the support assembly needs to be shortened, and the filling step is limited, which affects the filling efficiency

2. The support components are set on the roof support, pulling and moving the support will damage the temporary support of the roof

3. The bottom of the goaf is uneven, and the isolation device is fixed, resulting in incomplete isolation. After the paste solidifies, it is difficult to detach the bracket

4. During the process of pulling and moving the brackets, adjacent brackets interfere more, which affects work efficiency
