Description
Technical field
This patent is related to high-altitude working safety protection technology field, more particularly, to a kind of high voltage transmission line tower operation fall arrest dress
Put.
Background technology
Now with the high speed development of power industry, high-voltage and ultra-high transmission line of electricity uses large-scale steel tower, due to steel tower
It is all higher, to circuit work high above the ground certain risk is brought, in order to prevent operating personnel's accidental falling, ensure operating personnel
Personal safety, it is many it is contemplated that having gone out many schemes, numerous fall protection device for working at height come out, particularly high-voltage line
Tower T-shaped rail catching device, the overwhelming majority is all present；In upper and lower operation process, to slide the dumb, locking that falls unreliable etc. all
Many deficiencies and shortcoming.
The content of the invention
The purpose of this patent is directed at present；During T-shaped rail catching device has the upper and lower pylon of operation, slide not
The present situation of the locking that flexibly, falls many deficiencies such as unreliable and shortcoming, and a kind of high voltage transmission line tower operation fall arrest dress for providing
Put.
This patent solves the technical scheme that its technical problem used；The housing for using high strength steel to make is " C "
Type notch, " C " type structure draw-in groove coordinates with T-shaped rail, and draw-in groove corresponds to T-shaped rail inside both sides, respectively inlays by two
Block magnet, make its in moving up and down can not slidably, the front of the corresponding T-shaped rail in housing front, be provided with it is fixed multiple
Close the locking groove of piece, compound locking piece of stopping of stopping and enclosure slot the inside, housing outer end peace are fixed on by flat spring of stopping, with fixed screw
Dress torque arm, torque arm, locking cam are structure as a whole, are fixed together by torque arm fixing axle and housing, and locking cam the right is installed
Torque arm spring, the locking cam left side makes the locking pawl end for having latch ratchet and locking SR and coordinates, locking SR
Locking SR spring is installed, housing left side is fixed on by push button shaft, interconnect and constituted.
Wherein；Housing, torque arm, locking cam, latch ratchet, locking SR, torque arm fixing axle, push button shaft are used
High strength steel is manufactured, and compound locking stops piece rubbing surface for asbestos bakelite material, back clad steel plate, increased and T-shape rail
The rubbing surface in road, increase frictional force, when locking cam action, locking effect more preferably, due also to the chute of torque arm upwards to
It is interior, when making to move up, the stress point that pulls up of safety rope link it is basic in vertical top, the very smooth spirit of upward sliding
It is living, without catching phenomenon, safety rope link is linked into the chute of torque arm, and when personnel move down, translational speed and pulling force do not surpassing
Cross under the elastic force of torque arm spring, this patent smooth can be moved down, when move down speed accelerate suddenly, strength increase when, torque arm drive lock
Only cam, piece of being stopped to compound locking apply thrust, and compound locking is stopped, and piece is locked with T-shaped rail plane, stopping is slided, locking
Ratchet by locking pawl locking, prevent from sliding again, avoid and glide again, after only unlocking again, could again move and use,
During unblock；Hold torque arm, press the release torque arm of locking SR, torque arm resets naturally under the action of the spring.
The beneficial effect of this patent is：Due to draw-in groove inner edge be inlaid with magnet, will not be free in the movement with track
It is mobile, due also to employ the compound piece of stopping of large area, improve locking effect, due also to operation torque arm is employed upwards inwardly
Chute, when moving up operating personnel, can smooth flexible movement, due also to employing ratchet on locking cam shaft end
Structure, secure ratcs is fixed when there is tenesmus, is easy to personnel to process calmly, can be just continuing with after manual unlocking, due to
Go up some；Safety that is more convenient to use, being effectively guaranteed user really.

Specific embodiment
This patent is included in accompanying drawing：Housing (1) from T-shaped rail (9) with, " C " type structure draw-in groove (2), draw-in groove
(2) the internal both sides of T-shaped rail (9) are corresponded to, is respectively inlayed by two pieces of magnet (10), the corresponding T-shaped rail in housing (1) front
(9) front, it is provided with the stop groove of piece (8), compound locking of fixed compound locking and stops piece (8) by flat spring of stopping (17), with piece of stopping
Fixed screw (16) is fixed on housing (1) groove the inside, and torque arm (3), locking cam (4), torque arm (3), lock are installed in housing (1) outer end
Only cam (4) is structure as a whole, is fixed together with housing (1) by torque arm fixing axle (6), and locking cam (4) the right is installed and drawn
Arm spring (7), locking cam (4) left side makes the locking pawl (15) for having latch ratchet (13) and locking SR (11) and holds
Coordinate, locking SR (11) install locking SR spring (14), be fixed on by push button shaft (12) housing (1) left side connect
It is connected together and is constituted.
This patent due also to, the internal both sides of the draw-in groove (2) of housing (1) correspondence T-shaped rail (9), respectively inlay by two blocks of magnetic
Iron (10), makes the patent not moved in the case where any position does not have external force, wherein；Housing (1), torque arm (3), locking are convex
Wheel (4), latch ratchet (13), locking SR (11), torque arm fixing axle (6), push button shaft (12) use high strength steel
Manufacture.
This patent due also to, employ compound locking and stop piece (8)；Compound locking stops piece (8) rubbing surface for asbestos bakelite material
Material, back clad steel plate, increased the rubbing surface with T-shaped rail (9), when locking cam (4) is acted, locking effect more
It is good.
This patent due also to, torque arm (3) makes inside torque arm chute (5) upwards；When deployed, what is pulled up receives
Force is basic in vertical top, upward sliding very it is smooth flexibly, without catching phenomenon.
This patent due also to, safety rope link is linked into the chute (5) of torque arm (3), when personnel move down, translational speed
And pulling force, under no more than the elastic force of torque arm spring (7), this patent smooth can be moved down, when moving down, speed is accelerated suddenly, strength adds
When big, torque arm (3) drives locking cam (4), piece (8) of being stopped to compound locking applies thrust, and compound locking is stopped piece (8) and " T "
Type track (9) locking, stop movement, latch ratchet (13) by locking pawl (15) locking, prevent from sliding again, only unlock again
Afterwards, could again move and use, during unblock；Tense torque arm (3), press locking SR (11), unclamp torque arm (3) make its from
So reset.
Due to the unique design of this patent, due to draw-in groove (2) inner edge be inlaid with magnet (10), with T-shaped rail (9)
Will not be moved freely in movement, due also to the compound locking for employing large area is stopped piece (8), improve locking effect, due also to
Operation torque arm (3) employ upwards inside torque arm chute (5), when moving up operating personnel, can smooth flexible movement,
Due also to secure ratcs is fixed when latch ratchet (13) structure is employed on locking cam (4) left end, tenesmus is produced, it is easy to
Personnel process calmly, be manually pressed by locking SR (11) unblock after can just be continuing with, due to more than some；Use
Safety that is more convenient, being effectively guaranteed user really.
Above-described is only the optimal enforcement mode of this patent, it is noted that for the ordinary skill of the art
For personnel, on the premise of the art of this patent principle is not departed from, some improvement and replacement can also be made and technology is prolonged
Stretch, these improvement and replacement and technology extend the technology category that also should be regarded as this patent, also belong to the protection model of this patent
Enclose.
