Embodiment
The specific embodiment of the present invention is described in detail with reference to Fig. 1-Fig. 5：
The present invention includes hanging ladder body 1, and the hanging ladder body 1 includes the crossbeam between the montant I 11 and montant I 11 of both sides
12, hook I 13 is provided with the front end of the hanging ladder body 1, a montant II 14 is set between two montants I 11,
Slideway 141, and the bottom opening of the slideway 141 are provided with the montant II 14.The fixed form of montant II 14 is preferable
It is as follows：Card slot 121 is provided among crossbeam 12, montant II 14 is just caught in the card slot 121, then from bolt or welding
Mode is fixed.Since the upper end of hanging ladder body 1 may be fixed on different objects when fixed, such as cable or cross-arm,
But current hanging ladder front end is only fixedly installed hook, link up with unstable when being fixed with cross-arm, it is easy to slide, therefore,
In order to be adapted to different environment, jack 15 is provided with the front end of the hanging ladder body 1, is provided with the hook I 13
The contiguous block 131 coordinated with the jack 15, is equipped with coaxial pin hole on the jack 15 and contiguous block 141.
Sliding block 2, chain 3, chain wheel I 4 and chain wheel II 5, the bottom of the sliding block 2 is set to set in the slideway 141
Hook II 21 is equipped with, the hook II 21 stretches out the slideway 141 from the bottom opening of the slideway 141, and links up with II 21
It is open towards the rear end of hanging ladder body 1.Hook II 21 slides after hanging on cable in order to prevent, in the hook II 21
Side is provided with rubber antiskid layer 213.
Fluted 211 are set in the front end of the hook II 21, baffle 212, the gear are provided with the groove 211
Plate 212 is vertically arranged, and the bottom of baffle 212 and the front end of groove 211 are articulated and connected, and torsion is provided with articulated connection
Spring.In normal state, baffle 212 is vertical, and baffle 212 can be rotated along hinge joint into groove 211, and turn to baffle
In 212.
A cavity 22 is provided with the sliding block 2, is provided with a sphere 23 in the cavity 22, the sphere 23 with
One end connection of a piece tension spring 24, the other end of the tension spring 24 connect with the cavity 22 close to one end of hanging ladder body rear end
Connect, the effect of tension spring 24 is the pulling force to sphere 23 produced for offsetting chain due to gravity, and certainly, sphere 23 can be with
Square, however, it is preferred to for sphere, so can prevent sphere from being blocked in cavity 22.One end of the sphere 23 connects
Be connected to drawstring 25, the other end of the drawstring 25 through the hook II 21 after the groove 211 stretching with the baffle 212
Front end connection.In order to allow drawstring 25 to pull smoothly, further, the rear of the cavity 22 is located on the sliding block 2
A roller I 26 is provided with, roller II 27 is provided with the front end of the groove 211, the drawstring 25 bypasses the roller I 26
With roller II 27.
One end of the chain 3 is connected through the cavity 22 with the sphere 23, and the other end is connected with the sliding block 2；
The chain wheel I 4 is located at the front end of the montant II 14, and the chain wheel II 4 is located at the rear end of the montant II 14, and described
Chain 3 bypasses the chain wheel I 4 and chain wheel II 5.
Since operating personnel is in order to facilitate the operation, described in the bad grasp of high aerial operation balance, very painstaking and danger
Chain wheel I 4 and chain wheel II 5 are horizontally set in montant II 14, and the crank way is opening up.Set on the chain wheel I 4
Crank connecting pin is equipped with, and crank way is offered on montant II 14, crank 6 coordinates after passing through the crank way with crank connecting pin
The fit system of connection, crank 6 and crank connecting pin can use the crank mode on present tractor.Crank is opening up,
Operating personnel need not bend to operate when operating, and straight and upright upper body just can rotate crank 6, ensure that the safety of operating personnel.
, it is necessary to which fixed chain has prevented from moving again, around the crank way after hook II 21 is stuck on cable
Through hole I 142 is evenly equipped with, one week through hole II is also evenly equipped with the chain wheel I 4, after the through hole I 42 and the alignment of through hole II
Pluggable latch is fixed.It is so not only easy to operate, and reliability is high.
The application method of the present invention is as follows：I 13 front ends for being fixed on hanging ladder body 1 will be linked up with, hook I is then hung over into horizontal stroke
The position such as load or cable, then rides over the other end of hanging ladder body 1 on cable.After crank 6 and crank connecting pin are connected
Start to shake crank, hook II moves forward under the drive of chain, and cable is snapped into hook II after touching baffle 212, so
Rear baffle 212 resets under the active force of wind spring.So hanging ladder is just fixed.When needing to pull down hanging ladder, opposite direction turns
Shaking 6, chain 3 pulls sphere 23 to be moved to the left, so as to drive drawstring 25 that baffle 212 is pulled down to groove 211, sphere afterwards
23 are located at the left end of cavity 22, start band movable slider 2 and retreat, at this moment cable is exited out of hook II.
The above is described above in detail the preferred embodiment of the present invention and embodiment with reference to attached drawing, but the present invention is not
The above-described embodiment and examples are confined to, for those skilled in the art, are not departing from structure of the present invention
On the premise of think of, some other improvement and modification can also be made, these improvements and modifications also should be regarded as the protection model of the present invention
Enclose.
