Abstract
The utility model discloses a shed type roadway advanced support device. The shed type roadway advanced support device is mainly composed of a trapezoidal support which is formed by supporting legs and a supporting beam. The shed type roadway advanced support device is characterized in that a front detecting beam is arranged on the upper portion of the supporting beam, and a connecting steel plate is arranged on the front detecting beam. The shed type roadway advanced support device has the advantages of being simple in structure, safe and reliable, and good in supporting effect.
Description
Technical field
The utility model relates to a kind of mine roadway support device, specifically a kind of canopy formula lame advanced supporting device.
Background technology
Mining industry shed ding support cross-section shape of roadway commonly used is generally trapezoidal and the garden arch, and trapezoidal cross-section supporting steel used are generally mining i beam, and crowned section supporting steel used in garden are generally the mine U-shaped steel.In shed ding support tunnelling work progress, after tunnel, the place ahead has just excavated, need to the top board of supporting carry out leading interim control to the place ahead after, then carry out the operation of frame canopy, guarantee job safety.Now canopy formula lame advanced supporting mode commonly used is generally suspension type, and namely forestope is suspended in below rack beams, and the forestope front end is controlled the place ahead top board temporarily.Mainly there is following problem in this method: have a larger space between (1) forestope and top board, more difficult top board is directly controlled, supporting effect is poor; (2) forestope and the below that is connected jig and is positioned at rack beams, often encounter workman's health, affects the operation of workman's normal construction.
Summary of the invention
Task of the present utility model is to provide a kind of simple in structure, and is safe and reliable, the shed ding support lame advanced supporting device that supporting effect is good.
For realizing above-mentioned task, technical solution of the present utility model is:
A kind of canopy formula lame advanced supporting device, the trapezoidal supporting that mainly is made of rack leg and rack beams consists of, and its design feature is that forestope is set above rack beams, and junction steel plate is set on forestope.
The utlity model has simple in structure, safe and reliable, the advantage that supporting effect is good.
