The bracket anti-toppling device is rational in design, simple in structure, easy to manufacture and convenient to use; the working efficiency can be improved; a good effect of preventing the bracket from toppling is achieved; the working efficiency is effectively improved; and the bracket anti-toppling device is high in practicability and easy to popularize and apply.
Description
Technical field
The utility model belongs to the Safety of Coal Mine Production technical field of construction, relates in particular to a kind of metallic support tunnel and uses the support anti-tipping apparatus.
Background technology
In flat oblique gallery construction process; Metallic support set up very difficulty of installation, topple over easily in the unstable and erection process of supporting leg sometimes, bring potential safety hazard; Cause security incident in order to prevent that metallic support from toppling over, use interim stay bolt device that the metallic support of erection process is protected at present usually.This stay bolt apparatus structure is complicated, use inconvenience, badly influences operating efficiency and construction speed.
The utility model content
The utility model provides a kind of metallic support tunnel simple in structure, easy to use, that can increase work efficiency to use the support anti-tipping apparatus in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the support anti-tipping apparatus is used in the metallic support tunnel, comprises the jig of the supporting leg that is used for fixing support, is provided with draw rod tension mechanism between adjacent two jigs.
Said jig comprises bearing pin and four clamps; Four all inside bendings in clamp top form a hook; Wherein the adjacent and hook of two clamps is oppositely arranged, rotates an end that is located at bearing pin; In addition the adjacent and hook of two clamps is oppositely arranged, rotates the other end that is located at bearing pin, and four clamp left and right sides are fixedly connected with a rectangular plate that is parallel to bearing pin respectively, form one wedged hole between the two block length battens.
Said draw rod tension mechanism comprises the branch sleeve that has pull bar, has internal thread, flat junction plate, U type junction plate, leading screw; Branch sleeve peace junction plate is located at the pull bar two ends respectively; The bottom of leading screw one end and U type junction plate flexibly connects; The leading screw other end is threaded with branch sleeve, offers connecting hole respectively on flat junction plate and the U type junction plate, and pull bar is provided with two clapboards that cooperate with wedged hole.
Adopt technique scheme; Connect a jig on the supporting leg of metallic support respectively, through being fastenedly connected of draw rod tension mechanism, four supporting legs of two metallic supports are fixed together between adjacent two jigs; Can not topple over again, reach the good anti-effect of toppling over.
Four clamps of jig just in time wrap up supporting leg, and hook plays the effect that articulates back timber.
According to the distance between the adjacent legs; The draw rod tension mechanism use of can connecting; Connect through connecting pin between average junction plate and the U type junction plate,, thereby play the effect of tensioning through being threaded of leading screw and branch sleeve; Wedge shape grafting fast and wedged hole cooperates, and jig and pull bar are fixed as one.
The utility model is reasonable in design, simple in structure, be easy to make, easy to use, can increase work efficiency, support is played the good anti-effect of toppling over, improved operating efficiency effectively, practical, be easy to apply.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of draw rod tension mechanism in the middle of Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
Like Fig. 1～shown in Figure 3, the support anti-tipping apparatus is used in the metallic support tunnel of the utility model, comprises the jig of the supporting leg 1 that is used for fixing support, is provided with draw rod tension mechanism between adjacent two jigs.
Jig comprises bearing pin 2 and four clamps 3; Four all inside bendings in clamp 3 tops form a hook 4; Wherein two clamps 3 are adjacent and link up with 4 and be oppositely arranged, rotate an end that is located at bearing pin 2; In addition two clamps 3 are adjacent and link up with 4 and be oppositely arranged, rotate the other end that is located at bearing pin 2, and four clamp 3 left and right sides are fixedly connected with respectively between rectangular plate 5, the two block length battens 5 that are parallel to bearing pin 2 and form one wedged hole 6.
Draw rod tension mechanism comprises the branch sleeve 8 that has pull bar 7, has internal thread, flat junction plate 9, U type junction plate 10, leading screw 11; Branch sleeve 8 peaceful junction plates 9 are located at pull bar 7 two ends respectively; The bottom of leading screw 11 1 ends and U type junction plate 10 flexibly connects; Leading screw 11 other ends are threaded with branch sleeve 8, offer connecting hole 12 respectively on flat junction plate 9 and the U type junction plate 10, and pull bar 7 is provided with two clapboards 13 that cooperate with wedged hole 6.
When work was used, four clamps 3 were clamped the supporting leg 1 of the good metallic support of frame, and pull bar 7 passes between four clamps 3; Clapboard 13 on the pull bar 7 is inserted in the wedged hole 6, and pull bar 7 is fixed together through four clamps 3 and supporting leg 1, on the supporting leg 1 of another metallic support that adjacent preparation is set up, also presss from both sides upper clip 1 and pull bar 7 simultaneously; Two pull bars 7 can pass through rotational lead screw 11 free adjustment tensioning degrees; Put on connecting pin at flat junction plate 9 and the connecting hole 12 on the U type junction plate 10, such two metallic supports connect together, and the supporting leg 1 on both sides is fixed together; Two metallic supports become one, and that plays entire bracket anti-ly topples over effect.Thereby safe construction plays bigger safety precaution effect in the road, flat inclined gallery of steel lining, has improved operating efficiency effectively.
