Abstract
The utility model discloses a laneway bracket base, which comprises a base, wherein the base is divided into a left part and a right part; the left base and the right base are connected by a connecting piece; the upper end of the connecting piece is provided with a rotatable supporting body which is rotatably arranged on the connecting piece; the middle part of the rotatable supporting body is provided with an outer ring part which is outwards extruded; a plurality of distance rods are distributed along the circumference of the outer ring part; the upper end of each distance rod is provided with a sliding wheel; a groove used for containing the sliding wheel is arranged in the outer ring part; the position on the lower end part of each distance rod, which is contacted with the base, is provided with a spring component; the lower end of the base is provided with a travelling caterpillar band. According to the laneway bracket base disclosed by the utility model, the deficiency in the prior art is overcome, the laneway bracket base has the advantages of compact structure and reasonable layout; the lower end of the base is provided with the travelling caterpillar band, thereby being convenient for controlling movement; meanwhile, the upper end of the base is provided with a rotating body so as to conveniently regulate the position of an upper supporting plate; the rotating body is provided with a stress decomposition mechanism; the rotating body is provided with the distance rods, so that the stress can be effectively decomposed, the base is enabled to move conveniently, stress is guaranteed, and the laneway bracket base is safe and reliable to use.
Description
Technical field
The utility model relates to coal mining auxiliary equipment technical field, specifically belongs to a kind of excavation support base.
Background technology
Excavation support comprises base at present, base is connected with back timber by column and linkage, the governor motion that support does not have the various complex situations that may occur with roadway floor to adapt, to such an extent as to existing front and rear monolithic advance timbering is poor to the situation compliance of tunnel roof and floor injustice, in the time meeting the severe situation of roadway floor, support easily tilts and makes support connect top perpendicular to top board, is unfavorable for support state-maintenance; Owing to mining to the later stage, when coal seam coal is fewer and feweri, the position of excavation support just is more and more difficult to put, and regulates comparatively loaded down with trivial details simultaneously.
Utility model content
The purpose of this utility model has been to provide a kind of excavation support base, the deficiencies in the prior art are overcome, project organization compactness, rationally distributed, be convenient to control mobile by traveling crawler is set in base lower end, base upper end is provided with rotor simultaneously, be convenient to regulate the position of upper backup pad, upper backup pad is arranged on rotor, bear body of wall pressure, so just need on rotor, be provided with decomposition force mechanism, adopt and on rotor, establish multiple support bars, so just can effectively decompose stressed, ensure base conveniently moving, stressed secure, safe and reliable.
The technical solution adopted in the utility model is as follows:
A kind of excavation support base, comprise base, described base is divided into two parts in left and right, between left and right base body, connect by connector, connector upper end is provided with the rotation of rotational support body and is arranged on connector, rotational support body mid portion has outwards outstanding outer ring portion, be provided with multiple support bars along outer ring portion circle distribution, post upper has movable pulley, in outer ring portion, there is the groove of placing movable pulley, support bar bottom and base contact portion are provided with spring members, and described base lower end is not provided with traveling crawler.
Described left and right base body outside is provided with Anti-inclining mechanism, and described Anti-inclining mechanism is made up of sliding connector and cylinder, and sliding connector rotates and arranges on base, and sliding connector one end connects promotion cylinder.
Between described left and right base body and connector, be provided with multiple perforation, between multiple perforation, fix by fixed bar.
Described support bar and the angle of horizontal plane are 30-60 degree.
Described described spring members is spring or rubber pad.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is convenient to control mobile by traveling crawler is set in base lower end, base upper end is provided with rotor simultaneously, be convenient to regulate the position of upper backup pad, upper backup pad is arranged on rotor, bears body of wall pressure, so just need on rotor, be provided with decomposition force mechanism, adopt and on rotor, establish multiple support bars, so just can effectively decompose stressed, guarantee base conveniently moving, stressed secure, safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
Referring to accompanying drawing, a kind of excavation support base, comprise base 1, described base is divided into two parts in left and right, left, between right base body, connect by connector 2, connector 2 upper ends are provided with 3 rotations of rotational support body and are arranged on connector 2, rotational support body 3 mid portions have outwards outstanding outer ring portion 301, be provided with multiple support bars 4 along outer ring portion 301 circle distribution, support bar 4 upper ends have movable pulley 401, in outer ring portion, there is the groove 302 of placing movable pulley, described base lower end is not provided with traveling crawler 101, a described left side, right base body outside is provided with Anti-inclining mechanism, described Anti-inclining mechanism is made up of sliding connector 5 and cylinder 6, sliding connector rotates and arranges on base, sliding connector one end connects promotion cylinder, left, between right base body and connector 3, be provided with multiple perforation 7, fixing by fixed bar 8 between multiple perforation 7, be convenient to like this installing/dismounting.Upper backup pad is arranged on rotor, bears body of wall pressure, so just need on rotor, be provided with decomposition force mechanism, adopt and on rotor, establish multiple support bars 4, so just can effectively decompose stressed, guarantee base conveniently moving, stressed secure, safe and reliable.Support bar 4 bottoms and base 1 contact portion are provided with spring members 9, can effectively alleviate support bar stressed, extend support bar application life.
