Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: a kind of coal seam lane side drill site frame canopy method.
Wherein, the canopy body set up of the invention includes along the spaced multiple support components of the lane side, Mei Gezhi
Support component includes a capplce 2 of two canopy legs 1 of two canopy legs 1 and connection, and canopy body is cut into three sections using 36U shape steel, and divides
Not Wei two canopy legs 1 and a capplce, U-shaped steel can be matched with the lane side inner wall of U-shaped structure, and be close to the interior of lane side
Wall, support effect is good, stabilized structure, and the length of the U-shaped steel and wide ratio are 200:150, and two canopy legs 1 are symmetrical set, and canopy leg 1 has
There are a straight-bar and a curved bar, one end of one end connection straight-bar of curved bar, the other end of curved bar connects one end of capplce 2, directly
Bar and curved bar are integrally formed, and capplce 2 is arcuate structure, and capplce 2 and canopy leg 1 constitute U-shaped structure, and the both ends of capplce 2 pass through respectively
One limiting card cable 7 is fixedly connected with the upper end of a canopy leg 1, limiting card cable 7 by the interior inner hole with accommodating capplce 2 and canopy leg 1,
And limiting card cable 7 is fixed by fixing bolt, drill site 5 is located at the side of canopy body, and is provided with and dials between drill site 5 and canopy body
Door, being located on the capplce 2 for dialling door section for canopy body are welded with reinforcement 8, and there are two the settings of reinforcement 8, and the first reinforcement 8 is located at
At capplce inner sidewall medium position, the second reinforcement 8 is located at the side of the close drill site 5 of the second reinforcement 8.
The section of reinforcement 8 is v-shaped structure, and reinforcement 8 is fixed by welding on capplce 2, and door is dialled in being located at for canopy body
The canopy leg 1 of side at position is not installed in construction, so that drilling machine be facilitated to enter, reinforcement 8 is V-arrangement girder steel, and reinforcement 8
Upper surface tool there are two contact surface, and two contact surfaces are tightly attached on capplce 2, and by being welded and fixed, to solve
Lack side canopy leg 1 and the insufficient problem of the stability that generates, so that canopy body keeps firm dialling the structure at door position.
The tilt angle of the roof of drill site 5 and the tilt angle of roof are identical, and the bottom of drill site 5 is provided with drill site bottom
Plate, and drill site bottom plate, in being horizontally disposed with, the lower section of drill site bottom plate is the rock positioned at bottom, and drill site bottom plate passes through coal seam bottom
The rock support in portion is provided with anchor net on the inner wall of drill site 5, and the anchor pole 6 in insertion coal seam is provided on the roof of drill site 5 with fixation
Anchor net.
A kind of coal seam lane side drill site frame canopy method of the invention the following steps are included:
Preparatory trial assembly canopy body on the ground fixes all capplces 2 and the installation of canopy leg 1, after ensuring the installation of canopy body
Structural stability, so that canopy body energy normal mounting in lane side, and using safe.
Canopy body is set up along lane side, first canopy leg 1 is buried in the bottom of the two sidewalls of lane side, the lower end of canopy leg 1 is inserted into lane
Below ground in side, then the both ends of capplce 2 are separately connected to the upper end of two canopy legs 1, and capplce 2 and canopy leg have coincidence part
Point, it is no less than 400mm using the length that limiting card cable binds intersection and intersection, is then tightened by fixing bolt solid
It is fixed, it is only embedded far from the canopy leg 1 for dialling door side when canopy body, which is inserted into, to be dialled at door position, it is not buried positioned at the canopy leg 1 for dialling door side
If two reinforcements 8, which are respectively welded, is fixed on capplce 2 being located at two reinforcements 8 of installation for dialling the capplce 2 at door position
At middle part and right side half position, thus by 8 reinforced shed body of reinforcement, thus what supplement lacked because lacking canopy leg 1
Stability then proceedes to set up canopy body along lane side, and two canopy legs 1 of normal mounting and a capplce 2.
Dial door position at carry out drill site construction, along roof inclination angle excavate duct, in duct install anchor net with
The inner wall in duct is supported, then the anchor pole 6 of insertion roof is installed on the roof in duct, the lower end of anchor pole 6 is welded and fixed
At the top of anchor net, thus fixed anchor net, the bottom wall in duct is the rock along the bottom in coal seam.
The horizontally disposed drill site bottom plate of installation on the bottom wall in duct, horizontally disposed drill site bottom plate can facilitate the later period
Drilling machine construction, enable drilling machine even running on drill site bottom plate, to carry out safe bore operation.
A kind of coal seam lane side drill site frame canopy method of the invention, by being first inserted into canopy body and dialling door when setting up canopy body
Then section is being located at the top for dialling the capplce 2 of canopy body of gate segment and is installing reinforcement 8 at shoulder nest, and dialling when canopy body is inserted into
It is only embedded not buried far from the canopy leg 1 for dialling door side positioned at the canopy leg 1 for dialling door side when at door position, then carrying out drill site
When 5 construction, the inclination angle along roof is excavated, and carries out supporting, stable structure, finally at the bottom of drill site 5 by anchor net
Drill site bottom plate is arranged in portion, and the present invention has the characteristics that working procedure is simple, the construction period is short, construction is safer.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
