Abstract
The utility model discloses a rapid installation suspender for distribution grid cross arms. The rapid installation suspender comprises an upper pulley assembly and a lower pulley assembly, the upper pulley assembly is provided with an electric pole hoop, and the lower pulley assembly is provided with suspension rope suspension members. The upper pulley assembly and the lower pulley assembly respectively comprise support frames, and at least one pulley is disposed in each support frame through a wheel shaft. According to the suspender, labor intensity is largely reduced, safety factor of operation on rods can be improved, and installation operation efficiency of the cross arms can be greatly improved.
Description
Technical field
This practical electric construction tool technical field, relates in particular to a kind of distribution cross-arm Fast Installation suspender.
Background technology
The installation of traditional distribution cross-arm, adopts single-point lifting conventionally, and its method is, lifting pulley is fixed on to electric pole upper end, and lifting rope one end is through pulley, and the other end ties up to the middle part of cross-arm, by ground staff by cross-arm lifting to installation position, and in rear bar, personnel are fastened on its installation on electric pole.The defect of this mode is that if lifting rope ties up to the slightly deviation of position of cross-arm, when lifting, cross-arm can vertically be sling, and needs personnel on bar to be adjusted to horizontal level installation when installation, wastes time and energy; As lifting rope tied up to the centre position of cross-arm, can level lift by crane, but in the time winching to installation site, tether lashing location can affect again to install to be fixed, and needs equally can install after adjustment.Secondly, because cross-arm is heavier, operation inconvenience on bar in addition, adjusts cross-arm position and extremely bothers, and not only installation effectiveness is low, and seriously has unsafe factor.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, provides one can increase substantially cross-arm installation effectiveness, easy to operate, safe and reliable distribution cross-arm Fast Installation suspender.
The technical scheme taked is for achieving the above object: a kind of distribution cross-arm Fast Installation suspender, comprise top sheave assembly and lower sheave assembly, and described top sheave assembly arranges Hoop for electric pole, and lower sheave assembly arranges outstanding rope suspension member.
Described top sheave assembly and lower sheave assembly comprise respectively bracing frame, in support frame as described above, by wheel shaft, at least one pulley are set.
Lifting rope connector is set on the bracing frame of described top sheave assembly.
Distribution cross-arm Fast Installation suspender of the present utility model, because outstanding rope is that contact has been avoided cross-arm and electric pole connection position, and cross-arm remains level in lifting and installation process, so personnel only need righting cross-arm to carry out fitting operation on bar, greatly alleviate labour intensity, and improved the coefficient of safety of operation on bar.Simultaneously by the assembly pulley also corresponding labour intensity that alleviates Ground Operation personnel.Thus, also increased substantially the installation exercise efficiency of cross-arm.The utility model is simple in structure, easy and simple to handle, cheap, has good practical and popularizing value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, distribution cross-arm Fast Installation suspender of the present utility model, comprise top sheave assembly and lower sheave assembly, described top sheave assembly and lower sheave assembly respectively have a frame-type bracing frame 1,4, in support frame as described above 1,4, be installed with wheel shaft 3,8, on wheel shaft 3,8, be coated with by bearing the pulley 2,7 that at least one can freely rotate, be used for installing lifting rope 10, pulley 2 on top sheave assembly is fixed pulley, pulley 7 on lower sheave assembly is movable pulley, forms thus the assembly pulley that can alleviate cross-arm 5 lifting labour intensity.One side of the bracing frame 1 of described top sheave assembly is connected with Hoop for electric pole (not shown) by connecting bolt, and bracing frame 4 two ends, the bottom symmetries of described lower sheave assembly are fixedly connected with and are useful on is hook or the link 9 that connects outstanding rope 6.Bracing frame 1 bottom of described top sheave assembly can be fixedly connected with for being to connect lifting rope 10 connecting rings 11.
While using this suspender to carry out cross-arm installation exercise, first fixing the upper end of lifting rope 10 system is connected on connecting ring 11, and lifting rope 10 was worn successively to each pulley 2,7 of assembly pulley, then by Hoop for electric pole, top sheave assembly is fixed on to the top of electric pole by personnel on bar; Ground staff is to be respectively connected on described hook or link 9 by one end of two isometric outstanding ropes 6, and other end symmetric system is connected on the both sides of cross-arm 5 mid points to be installed; Can be pulled by ground staff the lower end of lifting rope 10, light and fast ground is the installation position to electric pole upper end by cross-arm 5 liftings, by personnel on bar by cross-arm 5 install fixing after, take off the outstanding rope 6 tying up on cross-arm 5, ground staff unclasps lifting rope 10, lower sheave assembly falls naturally by self gravitation, can carry out the installation of a time cross-arm.After the cross-arm on electric pole all installs, on bar, personnel unload top sheave assembly.In installation process, because outstanding rope 6 is that contact has been avoided cross-arm 5 and electric pole connection position, and cross-arm 5 remains level in lifting and installation process, so personnel only need righting cross-arm on bar, carries out like a dream fitting operation.
