Technical field
The utility model relates to backguy strand mill, especially relates to a kind of electric power circuit and sets up with portable hand ceeling mill.
Background technology
At present, need to promote in the events in operation of lead in the electric transmission line isolator replacing of routine, wire clamp replacing etc., because vertical span and vertical load are less, when utilizing the operation of assembly pulley cucurbit rope, ground 2-3 people can finish, and can time promote and put in place.But along with the increase that transmission line of electricity vertical span and vertical load, the lifting pulling force of assembly pulley cucurbit rope becomes original several times, and ground 3-5 people also is difficult to upgrade lead, and adopting usually increases by a cover assembly pulley cucurbit rope again on shaft tower, to reduce pulling force.Because cucurbit rope expansion and contraction is big (being generally 30%-40%), when utilizing conventional assembly pulley cucurbit to restrict lifting lead operations such as changing the straight line insulator, be easy to elongation after the cucurbit rope is stressed, can not once promote lead and put in place, need change the lifting suspension centre repeatedly, time-consuming, effort, inefficiency, and when changing the lifting suspension centre and change auxiliary pulley group cucurbit rope again, security and stability is poor.
The utility model content
It is a kind of that the purpose of this utility model is to provide
For achieving the above object, the utility model is by the following technical solutions:
A kind of portable hand ceeling mill of the present utility model, strand mill base is provided with strand mill frame, on the strand mill frame grinding roller is installed.Coaxial successively from inside to outside ratchet, the reducing gear of being fixedly connected with of one end of described grinding roller, the coaxial reducing gear that is fixedly connected with of the other end of grinding roller, the reducing gear at grinding roller two ends meshes with the concentric transmission gear that is located on the strand mill frame respectively, two transmission gears respectively with stir hand and be connected, be provided with the ratchet that cooperates with ratchet on strand mill frame, ratchet resets by the ratchet spring in the ratchet rotating shaft.
Described strand mill base be provided with the V-type bayonet socket that is used to hold fixing angle steel and with the corresponding movable deck of V-type bayonet socket, movable deck grinds base and is connected with twisting by bolt.
Above-mentioned portable hand ceeling mill, described movable deck is provided with clip.
Above-mentioned portable hand ceeling mill, described ratchet are provided with and are used to make ratchet to break away from the projection of ratchet.
The beneficial effects of the utility model are:
The utility model utilizes the principle of work of palm cucurbit and motor-driven strand mill, combines with the advantage of cucurbit twisting mill, adopts gear change to drive grinding roller and rotates, and the appropriate design gear multiplication makes full use of gear transmission and recently reduces lead lifting pulling force.The tail rope of cucurbit rope is entangled to the reel of coaxial rotation, and a people shakes strand mill handle, a people holds tail rope, can once promote lead and put the pulling force when reducing to promote lead in place.When successfully having solved the big lifting operating cost of vertical load when changing straight line insulator, wire clamp replacing etc. and promoting the lead operation, the drawback of effort, inefficiency, poor stability.
Adopt transmission gear, ratchet and grinding roller to combine, utilize the principle of work of palm cucurbit and motor-driven strand mill, combine with the advantage of cucurbit twisting to grind, adopt the engagement of transmission gear and reducing gear to drive the grinding roller rotation, make full use of gear transmission and recently reduce lead lifting pulling force.
Adopt strand mill base to be provided with to be used to hold fixing angle steel the V-type bayonet socket and with the corresponding movable deck of V-type bayonet socket, movable deck grinds base and is connected with twisting by bolt; Movable deck is provided with clip. can make this device and various model angle bar realize anchoring with angle steel for facing the anchor stress point, perhaps with the line bar for facing the anchor stress point, all can realize twisting and grind operation, convenient and swift, the saving human resources.
The utility model weight is easy to on-the-spot transportation and is not subjected to restrictions such as natural environment, workyard about 20kg, and on-the-spot use need not can be installed by special tool, and personnel need not carry out Special Training yet, as long as 2 people's compounding practices can realize promoting the lead operation.With low cost, the stable performance of field application, easy to utilize, maintenance cost is low, at ordinary times maintaining that need not be special.Especially when the transmission line wire lifting work of big crossing span, stable performance, easy for installation, simple to operate, successful solution tradition Work tool promote the difficult problem in big span, the construction of two division large-section lead.
The utility model can be applicable to the various events in operation that electric transmission line isolator replacing, wire clamp replacing etc. need to promote lead, reduce during on-the-spot the use lead promote pulling force, reduce the Ground Operation personnel, easy to carry, simple to operate, safety performance is good, can reach the purpose of simplifying task program, shortening production time, increase work efficiency simultaneously.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification sheets, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
