Abstract
The utility model discloses a wire lifting tool which comprises a screw rod, lifting rods and cross arms, wherein an adjusting spanner with a steering device is arranged in the middle of the screw rod; the upper end of the screw rod is connected with each cross arm through a U-shaped tool ring and a rope sleeve, and the lower end is connected with each lifting rod; each cross arm is arranged on each lifting rod; two lifting rods are provided, and an adjusting hole is formed beside each lifting rod; the two lifting rods are in dislocated connection through the adjusting holes so as to adjust the up-down distance for placing an insulator; two cross arms are mounted between the two lifting rods respectively; and an up-raising structure is arranged at the two ends of the cross arms respectively so as to prevent a safety belt from dropping and the feet from sliding when stepping on the cross arms. The wire lifting tool disclosed by the utility model is applied to high-place operation of power transmission lines, and fundamentally overcomes the limitation of the traditional operation mode; and the tool has compact structure and light weight, is convenient to transfer up and down, simple to assemble and disassemble and convenient to use, and improves the working efficiency and the operation safety factor. Since the tool is simple to process and assemble, the tool is easily popularized and applied to power construction and has obvious economic and social benefits.
Description
Technical field
The present invention relates to a kind of transmission line high-rise working instrument, particularly a kind of transmission line straight line pole operation lead promotes instrument.
Background technology
In the transmission line operation process, the operating personnel usually can carry out work down to lead on the shaft tower from cross-arm.During operation, the way that the lower wire process is traditional is on straight line pole: the staff earlier between lead and cross-arm frame one save 2 meters rope ladders how long, then along rope ladder on lead.
Change insulator if change suspension clamp or have a power failure, all will raise up lead.Traditional method is: the operating personnel is behind lead, and another person matches with him on cross-arm, is loaded on Lever Blocks between lead and the cross-arm, tightens up the Lever Blocks chain, and lead is mentioned.
In the entire job process, which position no matter operating personnel's safety belt be contained on the lead, no matter be on the lead, on the Lever Blocks or on the insulator, certain danger arranged all, can only rely on two pipe protections rope as main protection, hides some dangers for to job safety.
In sum, in present transmission line straight line pole rolls off the production line operation process,, use heavy instruments such as rope ladder, Lever Blocks, and have potential safety hazard because the entire job process is loaded down with trivial details.If can the lifting instrument be carried out integrated repacking, will improve operating efficiency.
Summary of the invention
The utility model is to present transmission line straight line pole deficiency and the defective that operation process exists that roll off the production line; Provide a kind of lead to promote instrument; This lead promotes rope ladder and the Lever Blocks that the alternative traditional work of instrument is used; Link to each other implementation tool integrated and oversimplifying, not only convenient construction but also can guarantee on-line operation personnel's safety with adjustable lifting rod with leading screw.
The technical scheme that the utility model adopts is following:
This lead lifting instrument comprises leading screw, lifting rod and stull.The adjusting spanner of band conversion direction device is housed in the middle of the said leading screw, and the leading screw upper end is connected with cross-arm through U type tool links and rope sling, and the lower end is connected with lifting rod, and stull is housed on the lifting rod.
Said lifting rod is generally two.According to the insulator voltage grade and the different of material of insulating, required installation of insulator or adjustable range are also different.In view of the above; The side of every lifting rod is provided with several adjustment holes; Two lifting rods can be in order to increase the distance up and down of its adjusting through adjustment hole dislocation connection one, and the upper end lifting rod links to each other with leading screw, and the lower end lifting rod connects also installs thread-lifting hook in order to the hook guide line.
Said stull is two, is loaded on respectively between two lifting rods, and the two ends place of each stull chooses the formula structure on being, and is available to prevent that safety belt from falling down and slippage when stepping on is pedaled in foot.
The utility model adopts leading screw to link to each other with lifting rod, and during operation, the operating personnel on the cross-arm is connected in this instrument between lead and the cross-arm earlier, suitably tightens up.Rolling off the production line the operating personnel can be along the stull of installing on the lifting rod of this instrument on lead, safety belt around hanging in the stull.When promoting lead like need, the operating personnel can tighten up leading screw on the cross-arm, makes on the lifting rod that is connected on the leading screw to move, thereby raises up lead.
The utility model is applied in the transmission line high-rise working, has fundamentally solved the limitation of traditional work method, the solid tool compact conformation; In light weight, to be convenient to transmit up and down, loading and unloading are simple; Easy to use, can increase work efficiency, and the coefficient of safety when having improved operation greatly.Because this lead promotes tool processes and simple and convenient assembly, is easy in power construction, apply, economic and social benefits are obvious.
Description of drawings
Accompanying drawing 1 is the structural front view of the utility model;
Accompanying drawing 2 is structure left views of the utility model.
Embodiment
Further introduce the embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2, the utility model mainly is made up of leading screw 2, lifting rod 5, stull 4 etc.
Leading screw 2 is processed for the all-metal alloy steel material, and the adjusting spanner 3 of band conversion direction device is equipped with in the centre, and leading screw 2 upper/lower terminals respectively have one of perforation, and lower end perforation 7 is connected with lifting rod 5, bores a hole and 1 can be connected with cross-arm through U type tool links and rope sling in the upper end.
During concrete construction, adopt bolt and nut to be fixed together leading screw 2 and lifting rod 5 upper ends, lifting rod 5 is according to field operation shaft tower insulator length, selects the adjustment hole 6 of two lifting rod 5 required correspondences and with bolt the two is fixed together.The below lifting rod penetrates U type screw and connects the hook that lifts lead in the perforation 7 down.Promptly accomplish the ground assembly working that this lead promotes instrument.
After the operating personnel puts in place on the shaft tower; Be passed to the cross-arm place to entire tool through transmitting rope; Operating personnel on the cross-arm penetrates U type screw, and utilizes rope sling to be fixed in leading screw 2 upper ends on the cross-arm after hooking lead to this instrument below hook earlier in last perforation 1; The adjusting spanner 3 of operation leading screw 2 suitably tightens up entire tool.The operating personnel can be along the stull 4 of installing on the lifting rod 5 of this instrument on lead; Install around safety belt in stull 4, make operating personnel's safety have the relatively fixed position of safety, if occur unexpected; Stull 4 also can tangle safety belt, and the people is unlikely to from high falling.During like need lifting and whereabouts lead, the leading screw that the operating personnel can operate on the leading screw 2 on the cross-arm is regulated spanner 3, and the lifting rod 5 that is connected on the leading screw 2 is moved up and down, thereby lead is promoted and the whereabouts.Accomplish the entire job process.
