Background technology
In recent years, improving constantly and the more sophisticated of line channel environment, for circuit along with line voltage distribution grade
Running the consideration of safety, the height of newly-built transmission line of electricity constantly raises, and causes personnel check and accept circuit and face in maintenance process
Increasing falling risk, thus Guo Wang company requires newly-built extra high voltage line and important 500kV and Above Transmission Lines
Anti-fall guide rail must be installed completely to strengthen personnel's safeguard protection during climbing tower.But, in circuit work progress, by
In problem and the integral molding structure of catching device body of construction technology, the mounted anti-fall guide rail of major part is all due to T-shaped
Guide rail merging precision exceed installation requirement cause actually used during catching device be often stuck in rail attachment point and cannot continue to move to,
Operating personnel is caused finally to have to abandon using catching device.Above-mentioned present situation result in anti-fall device and substantially performs practically no function, it is impossible to
Defencive function is played in personal safety to operating personnel.
In order to solve the problems referred to above, the present inventor is by the analysis to catching device action principle, it is judged that catching device is in reality
Border is stuck in rail attachment point during using and uses fixed groove to design mainly due to it, when this will seek guide rails assembling
Must be in certain accuracy rating, otherwise horizontal or longitudinal during guide rail docking installation is crossed skew and all can be caused anti-fall
Device is stuck, and then loses the protective effect to user of service.For the skew situation excessively of guide rail, the present inventor is to catching device
Body construction decomposes so that it is possess a certain degree of range of activity on horizontal and vertical, when rail attachment point blocks
Suitably expand the horizontal and vertical size of groove according to practical situation, make personnel pass through the inept guide rail of merging precision and connect
Point, recovers groove life size, and then the personal safety of continuation guarantee personnel subsequently, and this case is given birth to therefrom.
Summary of the invention
For these reasons, the invention provides a kind of movable catching device of transmission line of electricity, use movable structure, can be right

Detailed description of the invention:
In conjunction with shown in Fig. 1 to Fig. 5, a kind of movable catching device of transmission line of electricity, including the load-bearing chunk 1 of integral structure, load-bearing
It is provided only with monolateral groove on chunk 1, and the opposite side of load-bearing chunk 1 uses activity form to be connected with adjustment block 2, in adjustment block 2
Also being provided with monolateral groove, the groove on load-bearing chunk 1 jointly acts on the groove in adjustment block 2 and is connected to the anti-fall of transmission line of electricity
On guide rail.Offer rectangle groove (not marking in figure) at the middle part of load-bearing chunk 1, eccentric jam plate 3 be installed in groove,
Eccentric jam plate 3 is fixed in groove by eccentric lock board shaft, and eccentric jam plate 3 can rotate along axle.Eccentric jam plate 3 is dashed forward for personnel
When so dropping by locked for catching device on guide rail, thus protect the personal safety of operating personnel.Wherein, eccentric jam plate 3 also sets
There is through hole 32, during the maintenance of operating personnel's conducting transmission line, protection rope can be lain on eccentric jam plate through through hole 32.Work as operation
Personnel's normal operation and catching device along guide rail normally move time, eccentric jam plate 3 is positioned at the position described in Fig. 1, to catching device
Move and do not produce impact；When operating personnel occurs accidental falling, lie in the protection rope with operating personnel under gravity
Suddenly bias jam plate 3 is pulled downward on, make eccentric jam plate 3 and guide rail contact, and contact area increases, and connects to increase further
Touch frictional force, be additionally provided with large-area profile of tooth district 31 at eccentric jam plate 3 at guide rail contact, further increase contact friction
Power, utilizes the friction between guide rail by locked for catching device on guide rail, thus protects the safety of operating personnel.For convenience
Eccentric jam plate 3 can anti-fall locked protection back pull disappear can self-return, in one end of eccentric lock board shaft, bullet is installed
Spring (does not marks in figure).
Adjustment block 2 with the movable connection method of load-bearing chunk 1 is: as it is shown on figure 3, adjustment block 2 and the connection of load-bearing chunk 1
On face, being positioned at upper lateral and be provided with stopper slot 21, bottom is provided with spacing hole 22, stopper slot 21 and spacing hole 22 and is used to adjustment block
Fixing and the adjustment of range of activity of 2.Load-bearing chunk 1 is correspondingly provided with some installing holes with at adjustment block 2 assembling, adjusts
The top of block 2 is fixed on load-bearing chunk 1 through stopper slot 21 by screw, and bottom is inserted spacing hole 22 by latch 4 and fixed
On load-bearing chunk 1.The extracting and inserting of latch 4 for convenience, the head at latch 4 is additionally provided with draw ring 8.Further for keeping away
Exempt from unexpected the loosening of latch 4 to skid off, cause adjustment block 2 to shift at work, latch 4 is fixed by screw 7.Such as figure
Shown in 5, latch 4 inserts the part of adjustment block 2 and is arranged above with ring-type spacing zone 41, installs steel ball 9 in the bottom of screw 7 simultaneously,
After making the screw 7 installing hole from load-bearing chunk 1 insert, steel ball 9 embeds in spacing zone 41 just, to latch 4 at transverse shifting
Fix.
In order to reduce frictional resistance when catching device normally moves on anti-fall guide rail, with guide rail on load-bearing chunk 1
Contact position is provided with a transverse-roller 5, is provided with upper and lower two longitudinal rollers 6 in the groove of load-bearing chunk 1, exists simultaneously
Also upper and lower two longitudinal rollers 6 it are symmetrically installed in the groove of adjustment block 2.
There is the catching device of said structure in use, the groove on load-bearing chunk 1 and adjustment block 2 is stuck in anti-fall guide rail
On, one end of the protection with operating personnel being restricted lies in operating personnel's loins, and the other end lies on the through hole 32 of eccentric jam plate 3.
During operating personnel's normal operation, catching device is followed operating personnel and is moved along guide rail, is stuck when catching device runs into rail attachment point
When cannot pass through, first the protection rope lain on eccentric jam plate 3 is taken off and is lain on shaft tower by operating personnel, then is torn open by screw 7
Under, extract latch 4, move up and down adjustment block 2, expand the groove size between adjustment block 2 and load-bearing chunk 1, make catching device energy
Pass through rail attachment point.After catching device passes through, then by adjustment block 2 return, and turn back to latch 4 and screw 7 to adjustment block 2
Lock, so that catching device can play safeguard protection effect in whole process.
