Description
Technical field
The utility model belongs to colliery technical field of boring equipment, is related to a kind of adjustable digging laneway supporting shed of spacing
Frame.
Background technology
In the tunneling process of colliery, in order to prevent the generation of roof fall accident, it is necessary to carry out supporting to tunnel using frame.Tradition
U-shaped canopy support system in, the distance between two adjacent U-shaped supports are fixed, it is impossible to according to the requirement of the actual supporting in tunnel
And adjust, operational many inconveniences are caused, supporting effect is influenceed.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that prior art is present there is provided a kind of simple in construction, operation flexibly
The good spacing adjustable digging laneway supporting frame of convenient, supporting effect.
For realizing that the technical solution of the utility model purpose is as described below.
A kind of spacing adjustable digging laneway supporting frame, including multiple inverted U supports, are erected in each inverted U branch
The upper and lower part of mast body front and rear sides is respectively welded with a positioning steel tube, symmetrical between two neighboring inverted U support
The change range adjuster of length can be transversely even adjusted equipped with four, the two ends for becoming range adjuster are arranged with pluggable positioning steel
Shank in pipe.
The above-mentioned adjustable digging laneway of spacing is with supporting frame, and change range adjuster is by a sleeve pipe with internal thread hole
Connector, two symmetrical connect mounted in the L-type connector at thimble connector two and two locking nuts compositions, two L-types connections
The transverse bar pieces of device are fixed to can be inserted into provided with that can be fitted into the external screw thread of thimble connector, the vertical bar segment of two L-type connectors
Shank in the steel pipe of position, two locking nuts are set in the transverse bar pieces of a correspondence L-type connector.
The above-mentioned adjustable digging laneway of spacing is welded with one with supporting frame in the stage casing set of thimble connector outer tube wall
Adjusting nut.
The above-mentioned adjustable digging laneway of spacing with supporting frame, inverted U support by two root posts and by bolt and
Nut is even constituted mounted in the arch back timber of two root posts upper end.
During the utility model assembling product, multiple change range adjuster two ends are connected to each adjacent inverted U support one by one
On the corresponding column body of rod.In concrete application, according to the requirement of the actual supporting in tunnel, distance tune is become by rotating forward or backwards
The thimble connector on device is saved, increases or decreases the length of change range adjuster, and then make the distance between supporting on request
Elongate or shorten.
Compared with prior art, the distance between each adjacent inverted U support in supporting frame described in the utility model can
To adjust as needed, have the advantages that simple in construction, flexible and convenient operation, supporting effect are good.

Embodiment
Referring to accompanying drawing, the adjustable digging laneway of spacing described in the utility model is with supporting frame by multiple inverted U supports 5
And multiple change range adjuster compositions.The structure of inverted U support 5 is as shown in figure 1, it is by bolt 1, arch back timber 2, column 3
Constituted with fixing bolt 1, nut 4, a use is respectively welded with the upper and lower part of the column body of rod front and rear sides of inverted U support 5
In the fixed positioning steel tube 6 for becoming range adjuster.As shown in Figures 2 and 3, it is by one with interior spiral shell for the structure of change range adjuster
The thimble connector 9 of pit, two symmetrical L-type connectors 12 and 7 connected mounted in the two of thimble connector 9 or so, two lockings
Nut 8 and 11 is constituted.Wherein, the connecting portion of the traversing section of left side L-type connector 12 and thimble connector 9 for dextrorotation (left-handed) outside
Screw thread, the traversing section of right side L-type connector 7 is left-handed (dextrorotation) external screw thread, thimble connector 9 with the connecting portion of thimble connector 9
Two ends are respectively internal thread, and the stage casing of thimble connector 9 is welded with adjusting nut 10, the vertical bar of two L-type connectors 7 and 12
Duan Junwei bottoms carry the shank inserted in positioning steel tube 6 of tapering point.
Operation principle of the present utility model is such：The L-type connector 12 and 7 of the left and right sides of range adjuster will be become
Tapering point be inserted into respectively in the positioning steel tube 6 that two adjacent inverted U supports 5 are welded, realize two adjacent inverted U branch
The connection of frame.In concrete application, according to the requirement of the actual supporting in tunnel, rotate each in certain direction successively and become range adjuster
Adjusting nut 10, the concomitant rotation of thimble connector 9, the right side L-type connector 7 and left side L-type that are connected with thimble connector 9 connect
Connect device 12 can be movable relatively, become the length increase (reduction) of range adjuster, so as to increase (reduction) two adjacent inverted U supports
The distance between；Similarly, opposite direction rotates adjusting nut 10, and opposite direction is rotated thimble connector 9 therewith, with thimble connector 9
The right side L-type connector 7 and left side L-type connector 12 of connection can opposite direction motions, the length reduction (increasing of change range adjuster
Greatly), so as to reduce the distance between (increase) two adjacent inverted U supports.When the distance between two adjacent inverted U supports are proper
When after, tighten the locking nut 8 and 11 at the two ends of L-type connector 7 and 12, prevent thimble connector 9 to be connected with left and right sides L-type
Loosening is produced between device 12 and 7.Other inverted U supports 5 are linked in sequence again in connection method by becoming range adjuster according to this,
So as to the supporting frame formed a whole.
