Description
Technical field
The present invention relates to underground coal mine auxiliary construction equipment, specially a kind of torque multiplier of anchor rod.
Background technology
High pre-stress strength support system is especially suitable for high stress tunnel condition under strong mining influence through checking.The body
It is predominantly 2 points of core content：One is, using high intensity high rigidity reinforced anchor rod anchor cable, to increase supporting intensity；Two is using high
Pretightning force, provides strong early stage supporting intensity in time.High pre-stress strength support system proposes higher to construction equipment
Requirement, the applying of particularly high pre-stress becomes the key of construction, and existing anchor pole, anchor cable construction equipment can not substantially meet to be applied
Work is required.
The content of the invention
The present invention can not substantially meet asking for high pre-stress strength supporting to solve existing anchor pole, anchor cable construction equipment
A kind of topic, there is provided torque multiplier of anchor rod.
The present invention adopts the following technical scheme that realization：Torque multiplier of anchor rod, including counter-force arm section and torsion times
Increase part, torsion enlarged portion main body is formed by ring gear main body and cover combination, capping is supported by input shaft, and input shaft is worn
Cross ring gear main body and be connected with output planetary support body, output planetary support body is connected to counter-force arm, and output planetary support body is formed around
Planetary gear, planetary gear are specifically supported by planet wheel spindle and are distributed in ring gear main body, are provided between input shaft and ring gear main body
Former and later two thrust bearings, counter-force arm end are V-arrangement and are provided with bayonet socket.
During work, the circumference gear in ring gear main body is engaged with internal planetary gear gear, relative to revolve with internal planetary gear
Then speech, direction of rotation is contrary；Counter-force arm can prevent ring gear main body from rotating, and planetary gear is rotated around central axis,
So as to output torque.
Beneficial effects of the present invention are as follows：By increasing axial thrust bearing, strengthen overall anti-axial thrust ability；Close
The planetary stage rotational structure design of reason prevents the excessive heating under high rotational speeds；Counter-force arm flies improvement and is allowed to convenient connection anchor
Bar and rig, and adapt to the requirement of underground coal mine anchor pole pretension.Present configuration is simple, reasonable in design, reliable convenient, can
To realize that bolt pretension reaches 600kN or so, prefastening torque is made to reach 6 times of jumbolter.
