Abstract
The utility model discloses a special tool mounting ground wires on an electric pole or an iron tower in power conversion-transformation construction, comprising a hanging cross arm, a wire supporting crossbeam, a guide bar, a base, a screw rod and a ratchet wrench. A ground wire is arranged in the groove of the wire supporting crossbeam, the hanging cross arm is hung on angle steel on top of the electric pole or the iron tower, and then the ground wire can be lifted up by wrenching the ratchet wrench to drive the screw rod and the wire supporting crossbeam to rise. Thus, the utility model changes the original construction method with shoulders and handspikes, lightens labor strength, raises construction progress and ensures construction safety.
Description
The utility model relates to a kind of bar, tower ground wire raiser that is used to send the power transformation construction work.
So far, send the installation method of ground wire in the power transformation circuit to be: earlier ground wire is hung on the coaster of ground line bracket at electric pole or iron tower top, then by the people pickaback or the way of thick stick sled again ground wire is promoted on the wire clamp from coaster, cable clip bolt is clamped, can finish.The shortcoming of this method is: efficient is low, and labor strength is big, particularly in work high above the ground, promptly industrial accident can take place slightly accidentally.
The purpose of this utility model is to provide a kind of and reduce labor intensity, improve speed of application, safe and simple specific purpose tool for ground wire installer in the transmission and transformation engineering.
This purpose can reach by adopting " shaft tower ground wire raiser ".Lifter mainly is made of holder line crossbeam, leading screw and a ratchet spanner, base, two guide posts and a suspension cross-arm.During construction, earlier ground wire is moved on the holder line crossbeam from coaster, to hang then on the angle steel that cross-arm is suspended to electric pole or iron tower top, pull ratchet spanner more repeatedly, then ask the line crossbeam moving on two guide posts under the driving of leading screw, ground wire is also raised simultaneously, when waiting to rise to the wire clamp position, can clamp wire clamp, install and just can finish.
Below by drawings and Examples the utility model is described in further detail.
Fig. 1 is the front view of lifter.
Fig. 2 is the C-C cutaway view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is the B-B cutaway view of Fig. 1.
Referring to accompanying drawing.Base (33) is positioned at the bottom of instrument, and its symmetrical centre has a through hole, and screw mandrel (13) passes from this hole.The lower end of screw mandrel (13) is by bearing (17) supporting that is contained in this through hole, and the upper end is fixed together with pin (12) and holder line crossbeam (11).With screw thread two guide posts (10) that are being fixedly connected, the upper end of guide post is fixing with bifurcation shape jaw (2) respectively by pin (1) respectively in the left and right sides that is symmetrical in the screw mandrel center line on base (33).Hang cross-arm (5) and be circular arc, its two ends is porose, and an end is hinged together by straight pin (3) and a jaw, and the other end is inserted in another jaw, and another straight pin (3) can successfully insert or extract in the hole that hangs cross-arm and this jaw.So, hang between cross-arm and two jaws one of formation and can open the mechanism that can close around straight pin (3).Holder line crossbeam (11) is Contraband shape, and left-right symmetric has two through holes on its web.The external diameter cunning of the diameter in hole and guide post (10) is joined.Two guide posts pass from this two hole respectively.Simultaneously, the Contraband shape web central authorities at holder line crossbeam are shaped on a semicircle holder line groove (35) vertical with web.And, a semicircle holder line groove (36) that radius is less is respectively arranged on two side plates of Contraband shape, the center line of these two semicircle holder line grooves is parallel with Contraband shape web.The radius of groove (35) and (36) equates with the ground wire radius of two kinds of specifications of thickness respectively, they suddenly line use.Also be equipped with one in the bottom of screw mandrel (13) near the place, last plane of base (33) and can drive the upper and lower mobile ratchet spanner of screw mandrel (32).As long as pull ratchet spanner, then ask the line crossbeam to do to rise or fall motion with screw mandrel.In addition, an electric pole circular arc bracing frame (20) is positioned at a side of base (33).This bracing frame comprises two poles (21) of an arc plate and vertical welding with arc plate, and these two poles can be inserted respectively in the hole of bearing side, also can extract from the hole.Like this, also make things convenient for the dismounting of this instrument in the vanning transportation, dwindle the packing case volume.And, when on iron tower, ground wire being installed, also can lay down electric pole circular arc bracing frame, with weight reduction.
Secondly, for reduced volume, convenient transportation also can be divided into two sections and can folding to the handgrip of ratchet spanner (32), promptly two intersegmental be faucet structure, and two is intersegmental hinged by pin (26), can realize this purpose.
The using method of this lifter is:
When being used for the installation of iron tower ground wire, shed electric pole circular arc bracing frame (20), open and hang cross-arm (5), ground wire is moved to the groove (35) of holder line crossbeam from coaster, close and hang cross-arm (5), again it is suspended from the angle steel at iron tower top, pulling ratchet spanner (32) holds up ground wire, after rising to the line height, hold cable clip bolt, take off lifter and get final product.
When being used for the electric pole ground wire and installing, with the difference of iron tower be: (1) loads onto electric pole circular arc supporting bracket (20), and with its arc plate by to the electric pole cylindrical, rise and support positioning action; (2) ground wire is put to the groove (36) of holder line crossbeam.All the other steps are identical.
The utlity model has following advantage and good effect:
1, owing to handle is artificial pickaback, the hoisting way of thick stick sled is changed into specific purpose tool and hoisted, Thereby greatly alleviated installer's labour intensity, improved installation rate, particularly prevented the generation of casualty accident.
2, this instrument is in light weight, and is simple in structure, easy to operate, surely can obtain installer's favor.
