Abstract
The utility model relates to the mechanical field of the electrical and machinery industry, in particular to a lifting traction device for a cable terminal, which comprises a supporting column, a hoisting frame, an upper pulley, a lower pulley, a wire rope, a cable tension meter and an electric hoist, wherein the hoisting frame is arranged at the upper part of the supporting column; the upper pulley is arranged at the upper end of the hoisting frame; the lower pulley is arranged at the lower part of the supporting column; the wire rope winds the upper pulley and the lower pulley; the cable tension meter is arranged on the hoisting frame; the electric hoist is arranged at the lower end of the cable tension meter; in addition, one end of a cable is connected with the electric hoist, and the other end of the cable is connected with a twisting resistant rotary connector. By adopting the technical characteristics, the lifting traction device needs small working space, can also lift larger cross section of the cable rapidly, can closely monitor the pulling force when lifting and tugging the cable, can prevent a cover layer of the cable from fracturing caused by the overlarge lifting force of the electric hoist, can prevent the cable from wringing, twisting and deforming during the stressed process, can rotate 360 degrees, and ensures that the cable can pass through a pulley groove in a minimum frictional force as well as the electric hoist can output the minimum tractive force.
Description
Technical field
The utility model relates to the electrical and machinery industry mechanical field, is specifically related to a kind of cable terminal and promotes draw gear.
Background technology
Increase along with power consumption, the construction working amount of cable terminal not only rolls up, and sectional area is also continuing to increase, but owing to improving constantly of land price, the space of cable terminal installation site is more and more narrower, and particularly the lifting traction problems of cable terminal has become the road blocking tiger of installation.Continually developing of high residential building, the generally use of household electrical appliance causes the cross-section of cable to amass and continues to increase, and maximum reaches 4*150mm
2Cable heavy in section like this is through 90 ° elbow, difficulty is big, improving constantly of land price, make the space of installation site of joint box more and more narrower, further strengthen cable terminal and promote the difficulty that traction is laid, have a strong impact on the progress of power construction, and the cable terminal heavy in section that has is that traction is motionless by manpower.Therefore, be badly in need of research and development one cover and replace the artificial electric hoist draw gear that promotes cable terminal.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of cable terminal and promotes draw gear, and this device working space is little, again can the big cross-section of cable of fast lifting, and can promote traction to cable and carry out the pulling force of overall process and monitor.
A kind of cable terminal promotes draw gear, comprise pillar stiffener, be located at pillar stiffener top raising legs, be hung at raising legs upper end top sheave, be located at the pillar stiffener bottom lower sheave, be set around top sheave and lower sheave steel rope, be located at cable tensiometer on the raising legs, be located at the electric block of cable tensiometer lower end, described steel rope one end links to each other with electric block, the other end changes adaptor union with anti-twisting and links to each other, described anti-twisting is changeed adaptor union and is provided with cable grip, and described cable grip is installed on cable terminal.
Described pillar stiffener lower end is provided with runners, the entablatrance of described raising legs is provided with a plurality of hanging holes, the cross sill of described pillar stiffener also is provided with a plurality of hanging holes, the hanging hole of described entablatrance is equipped with two swivels, the hanging hole of described cross sill also is equipped with a swivel, described top sheave and electric block are installed on respectively on the swivel of entablatrance, and described lower sheave is installed on the swivel of cross sill, and swivel and electric block can be according to adjusting flexibly about actual lifting situation.
Described raising legs is adjustable U type frame, establishes a symmetrical adjustment hole every 0.2 meter, and described pillar stiffener correspondence is provided with adjustment hole, and described adjustment hole is provided with binding bolt, can adjust height up and down according to the actual position of switch box, and described raising legs top is provided with by frame.
Owing to be provided with above-mentioned technical characterictic, this device working space is little, again can the fast lifting big cross-section of cable, cable is promoted traction carry out the pulling force of overall process and monitor, can prevent that the electric block hoisting force from crossing the fracture of ambassador's cable sheath simultaneously, can prevent that cable is in stressed process, wringing, torsional deflection, can 360 ° of rotations, guarantee cable with the friction of minimum through pulley groove, the minimum tractive force of cucurbit output.
