Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model provides a continuous movable temporary support device, this continuous movable temporary support device includes direction channel-section steel 1 and adjusting screw 3, direction channel-section steel 1 is equipped with guide way 2, adjusting screw 3 includes top nut 4, group stock 5, support tray 6, group nut 7, rotatory hand (hold) 8, adjusting screw 3 begins to pass guide way 2 upwards from top nut 4, block to support tray 6 department, so that support direction channel-section steel 1 with support tray 6, adjust the height of direction channel-section steel 1 so that it fully contacts the roof through adjusting the height of group nut 7 below support tray 6; a certain gap is formed between the anchor rod 5 and the guide groove 2 of the guide channel steel 1, so that the guide channel steel 1 can slide on the anchor rod 5, and in the use state, the continuously movable temporary supporting device is connected with a top anchor rod screw head of a tunnel top plate through a top nut 4 and compacts the guide channel steel 1 and the tunnel top plate through adjusting a top nut 7.
For further understanding of the present invention, the working process thereof will now be further described.
1. When the device is used, after the permanent support of a working face is completed, one adjusting screw rod 3 penetrates through a guide groove 2 of a guide channel steel 1, a top nut 4 is screwed on the anchor rod screw head of a supported first row of top anchor rods, the other adjusting screw rod 3 penetrates through the guide groove 2 and is screwed on the anchor rod screw head of a second row or a third row of top anchor rods, and the guide channel steel 1 is pushed so that the foremost end of the guide channel steel 1 supports the head of a roadway and is used for supporting the empty top range of the head of the roadway without the permanent support;
2. Adjusting the nut 7 of the two adjusting screws 3 to enable the supporting tray 6 to tightly press the guide channel steel 1, and the guide channel steel 1 tightly presses the top nut 4 so that the guide channel steel 1 fully contacts the top plate;
3. After the forward permanent support is continued, only the adjusting screw 3 at the rear end needs to be dismounted from the head of the anchor rod of the top plate of the roadway, penetrate out of the guide groove 2 of the guide channel steel 1, and then push the guide channel steel 1 forward, so that the foremost end of the guide channel steel 1 props against the head of the roadway;
4.
