Using said structure, staff's rotating shaft is facilitated by handwheel, it is easy to operate.
More preferably:The bolt body upper surface is provided with right-angled intersection and for showing cam rotation status Index line.
Using said structure, because anchor pole is absorbed in injecting cement paste, two side shields can not be observed whether in stretching shape State, the right-angled intersection index line set by bolt body upper surface, the retracted positions of two side shields can be appeared clearly from.
More preferably:The drive device includes rotating shaft, abutted with two side shields and in the abutting block of circular platform type, institute State abutting block to be fixed in rotating shaft, a threaded rod is threadedly coupled in the bolt body, threaded rod one end passes through a thrust bearing It is connected with axis of rotation, the other end extends outside bolt body, and provided with a handwheel for facilitating rotating threaded rod.
Using said structure, promote its threaded rod to bottom offset with respect to bolt body by handwheel rotating threaded rod and turn Axle is arranged to circular platform type towards bolt body basal sliding, by abutting block and abutted with two side shields, makes its two side shield slowly To bolt body lateral displacement, in embedded injecting cement paste;Due to being rotatablely connected between threaded rod and rotating shaft by thrust bearing, can make During its rotating threaded rod, it is not required to rotate whole rotating shaft, operation is more easily laborsaving.
More preferably:One end above and below Dao You oblique angle of the baffle plate with respect to bolt body.
Using said structure, by the oblique angle having on baffle plate, make its baffle plate towards injecting cement paste one end be in oblique angle state, just In inserting in injecting cement paste.
More preferably:There is the oblique angle in convenient insertion anchor hole the bolt body lower end.
Using said structure, the oblique angle having by bolt body lower end, it is easy to insert anchor pole in anchor hole.
More preferably:The baffle plate is evenly arranged with some groups along bolt body length direction.
Using said structure, by multigroup baffle plate of setting, strengthen the stable fastness between anchor pole and injecting cement paste, enter one Step avoids anchor pole from coming off, and strengthens the intensity, stability and bearing capacity of whole rock-soil layer.
In summary, the utility model has the advantages that:
1st, by setting bolt body both sides and the telescopic baffle plate of relative bolt body, enhancing anchor pole and injecting cement paste are reached Between fastness, be easy to deposit anchor pole effect;
2nd, the flexible of two side shields is promoted with moving cam by handwheel rotating shaft, reaches easy to operation, improve work effect The effect of rate.
