Description
Technical field
The utility model relates to a kind of mine laneway brace summer protective device.
Background technology
Along with the development of China's industry cause, the mineral products needed in the industrial production constantly increase, therefore the exploitation of mineral resources area that China is annual constantly increases, but thing followed accident of mine disaster is also in continuous increase, mine laneway generally adopts H-shaped steel supporting mode, along with the change of ore deposit pressure, the supporting leg of local, tunnel steel I-beam may collapse under pressure, be easy to cause cave in accident as do not adopted remedial measures in time, but set up supporting leg and need the long period in tunnel, interim bracing or strutting arrangement is difficult to again bear larger pressure.
Summary of the invention
For the defect existed in prior art, the utility model provides a kind of mine laneway brace summer protective device, can carry out an overfill protection fast, prevent cave in accident from occurring to the steel I-beam of supporting leg breakage.
Concrete technical scheme is: a kind of mine laneway brace summer protective device, comprise base and supporting mechanism, base is horizontally disposed with, the bottom center position of base is provided with rotating disk, rotating disk is horizontally disposed with and the bolt passed through perpendicular to base end face is connected with base, rotating disk and bolt are matched in clearance, and rotating disk circumference is provided with the equally distributed gear teeth, the bottom surface of base is provided with two T-shaped chutes about rotating disk center of circle symmetry, supporting mechanism comprises gripper shoe, jig and drilling rod, gripper shoe is slided respectively and is arranged in two T-shaped chutes, gripper shoe in two T-shaped chutes stretches out that one end is outside to T-shaped chute respectively and gripper shoe external part in two T-shaped chutes is not identical, gripper shoe lower surface is provided with the projection extend out to outside T-shaped chute, the side of projection be provided with rotating disk outside the teeth of gear teeth meshing, jig and drilling rod are arranged in the part that gripper shoe stretches out outside T-shaped chute, and drilling rod is near the end of gripper shoe external part, drilling rod vertically runs through gripper shoe and with gripper shoe for being threaded, jig comprises montant and horizon bar, montant is vertically arranged and its lower end is fixedly connected with gripper shoe upper surface, horizon bar is perpendicular to montant, horizon bar one end is fixedly connected with montant upper end, the other end is towards base centre position.
Described base length is 1m.
Described gripper shoe length is 0.8m.
The utility model structure is simple; cost is low; when have in tunnel have supporting leg to be damaged time; utilize many this devices of cover with the use of being fixed together by the girder steel with intact supporting leg adjacent with its both sides for steel I-beam corresponding for the supporting leg of damage fast; steel I-beam is protected; thus can obtain the longer time supporting leg damaged is repaired or changed, eliminate and repairing or changing the landslide hidden danger existed during supporting leg.

Fig. 3 be in Fig. 2 A-A to structural representation.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of mine laneway brace summer protective device, comprise base 1 and supporting mechanism, base 1 length is 1m and is horizontally disposed with, the bottom center position of base 1 is provided with rotating disk 2, rotating disk 2 is horizontally disposed with and the bolt 3 passed through perpendicular to base 1 bottom surface is connected with base 1, rotating disk 2 and bolt 3 are matched in clearance, and rotating disk 2 circumference is provided with the equally distributed gear teeth 4, the bottom surface of base 1 is provided with two T-shaped chutes 5 about rotating disk 2 center of circle symmetry, supporting mechanism comprises gripper shoe 6, jig 7 and drilling rod 8, gripper shoe 6 length is 0.8m, gripper shoe 6 is slided respectively and is arranged in two T-shaped chutes 5, gripper shoe 6 in two T-shaped chutes 5 stretches out that one end is outside to T-shaped chute 5 respectively and gripper shoe 6 external part in two T-shaped chutes 5 is not identical, gripper shoe 6 lower surface is provided with the projection 9 extend out to outside T-shaped chute 5, the side of projection 9 is provided with the teeth 10 engaged with the gear teeth 4 outside rotating disk 2, jig 7 and drilling rod 8 are arranged in the part that gripper shoe 6 stretches out outside T-shaped chute 5, and drilling rod 8 is near the end of gripper shoe 6 external part, drilling rod 8 vertically runs through gripper shoe 6 and with gripper shoe 6 for being threaded, jig 7 comprises montant 11 and horizon bar 12, montant 11 vertically arranges and its lower end is fixedly connected with gripper shoe 6 upper surface, horizon bar 12 is perpendicular to montant 11, horizon bar 12 one end is fixedly connected with montant 11 upper end, the other end is towards base 1 centre position.
In use, rotary turnplate 2, make two gripper shoes 6 respectively to two end motions of base 1 by the cooperation of the gear teeth 4 and teeth 10, as shown in Figure 1, find out steel I-beam corresponding to the supporting leg of damage 13 and be adjacent intact steel I-beam 14, between the top flange that the horizon bar 12 of two jigs 7 is positioned over steel I-beam 13 and steel I-beam 14 respectively and bottom flange, then rotating disk 2 is reversely rotated, two gripper shoes 6 are shunk to base 1 centre position, be fixedly connected with steel I-beam 14 with steel I-beam 13 by two jigs 7, then rotating disk 2 is locked by screwing bolts 3, thus two gripper shoe 6 positions are fixed, last rotary drill rod 8, drilling rod 8 is screwed in the ore body above steel I-beam 13 and steel I-beam 14, thus provide certain support force upwards for this device.
Utilize said method, adopt many this devices of group to be fixedly connected with steel I-beam 14 by steel I-beam 13 simultaneously, ensure that the steel I-beam 13 that the supporting leg of damage is corresponding can bear larger load, prevent cave in accident from occurring, the supporting leg be convenient to damaging repairs or replaces.
