Description
Technical field
The present invention relates to cable apparatus for examination and repair technical field more particularly to a kind of cable cover lifters.
Background technique
With the development of urbanization, urban district and converting station electric power cable run will increasingly increase, into cable duct patrol, in advance
It is also increasingly frequent to order inspection work for a trial.In order to reach the requirement of resistance to compression and external force damage prevention, cable passage cover board requires to do thicker heavier.
Usually need more people's cooperations that could open cable cover in operations such as maintenance, and outdoor cable cover board has as time goes by
It is a degree of to expand with heat and contract with cold, along with cable passage is commonly distributed on pavement, the easy dust accumulation contamination in cable cover gap
Cause cable cover to be closely attracted with the borehole wall, increases difficulty of uncapping.It depends manpower alone to be difficult to open cover board, and needs longer consumption
When.If the time for robbing reparation will be largely effected on by meeting rush repair work.In conclusion current cable cover plays double recipe
Formula is there are inconvenient, the problems such as needing to expend a large amount of manpowers and low operating efficiency.
Summary of the invention
The present invention is the problems such as crane system of solution existing cable cover board is inconvenient and laborious, provides a kind of cable
Cover board lifter.
To realize the above goal of the invention, and the technological means used is:
A kind of cable cover lifter, including bracket, transmission mechanism and pulley mechanism,
The bracket includes upper mounted plate and bottom plate, is opened up respectively at the center of fixed plate and bottom plate
Through-hole；
The transmission mechanism include master gear, from gear, handle and set axis, the handle pass through the master gear center with
The master gear is fixedly connected, and the set axis sequentially passes through described from gear centre and the through-hole of the first fixed plate and described from tooth
Wheel is fixedly connected, and the pulley mechanism and the set axis are rotatablely connected and between the first fixed plate and the second fixed plate；
It further include rope and hook, on pulley mechanism, the other end of the rope passes through the one ends wound of the rope
The through-hole and hook of bottom plate connect.
Since transmission mechanism is provided with master gear with from gear in this programme, the rotation of master gear is controlled by shake handle
And drive from gear and rotate, to drive set axis and rotationally connected pulley mechanism rotation, realize rope in pulley mechanism
On kinking and unwrapping wire, that is, realize the lifting of hook.The liter of hook is more effortlessly controlled using the transmission mechanism of gear combination
Drop, so that the structure of cable cover lifter of the present invention is more reasonable.
Preferably, the pulley mechanism includes the first lateral shaft, the second lateral shaft, the first I-beam wheel, the second I-shaped
Take-up pulley and rope are taken turns,
The first lateral shaft and the second lateral shaft are parallel and be relatively arranged in the four columns, described first
Lateral shaft and the second lateral shaft are located at the centre of upper mounted plate and bottom plate；
The center of first I-beam wheel passes through and fixes to the first lateral shaft, and the center of second I-beam wheel passes through
And it is fixed on the second lateral shaft, first I-beam wheel and second I-beam wheel are symmetrical arranged；
The center of the take-up pulley passes through and fixes to the set axis, and the take-up pulley is vertically arranged to upper mounted plate under
Among fixed plate, for the one ends wound of the rope in take-up pulley, the other end of the rope passes through the through-hole and extension of bottom plate
In hook connects.Kinking of the rope on pulley mechanism is realized in the running of transmission mechanism when promoting cable cover, that is, realizes hook
It rises.
Preferably, the rope has two, further includes symmetrically arranged two pendants, two ropes on the take-up pulley
One end of rope is hung on two pendants respectively and is wound in respectively the first I-beam wheel and the second I-beam wheel, two ropes
The other end passes through the through-hole of bottom plate and hook connects.
Preferably, lifter further includes stop pin, and the stop pin passes through upper mounted plate and is movably set in from gear and master
Between gear.Since stop pin can stop the rotation of principal and subordinate's gear, that is, the running of transmission mechanism and pulley mechanism is limited, thus
Fixed cable cover lifts height；Stop pin is extracted to the rotation for having restored principal and subordinate's gear.
Preferably, the bracket further includes four columns, and fixed plate is fixed at the top of the four columns,
The bottom plate is fixedly installed on the underface of fixed plate by the four columns.
Preferably, the four columns are respectively arranged below idler wheel.Since this cable cover lifter uses Shi Yaoyi
To the surface of cable cover, idler wheel, which is arranged, keeps the movement of the lifter more convenient laborsaving.
Preferably, the hook is crotch or I-shaped hook.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Due to transmission mechanism of the invention be provided with master gear with driven when from the gear combination of gear, rotating master gear from
Gear rotation realizes kinking of the rope on pulley mechanism to drive set axis and rotationally connected pulley mechanism rotation
With unwrapping wire, that is, realize the lifting of hook.The lifting of hook is more effortlessly controlled using the transmission mechanism of gear combination；While by
It hang on two pendants on take-up pulley respectively in two ropes and is wound in the first I-beam wheel and the second I-beam wheel respectively, rotates and receives
Line wheel can two ropes of synchronous drive so that the structure of cable cover lifter of the present invention more it is firm rationally, solve existing
There is the problems such as crane system of cable cover is inconvenient and laborious.
