Description

Shaft tower cable platform work protective cradle
Technical field
Power construction field is the utility model is related to, especially a kind of shaft tower cable platform work protective cradle.
Background technology
With the quickening of urbanization process, from the utilization of urban environmental protection angle and limited space resources and urban Build angle to set out, in construction and reform works in downtown district planning, often require that abovegrade piping enters ground, keep appearance of city attractive in appearance.Institute Being gone underground by power network by open wire line form turns into inevitable choice in the form of cable.
The shaft tower of overhead transmission line is divided into two kinds of forms of steel tower and steel pipe pole.For the cable termination tower of steel pipe pole, often divide Voltage class sets cable platform on shaft or sets independent cable platform.Cable platform is that aerial condutor connects with cable The place connect, to prevent idler from climbing up and workmen's lower work is conveniently generally located on 6 meters away from ground eminences, work Personnel belong to work high above the ground, according to code requirement when installing cable accessory or repair apparatus on cable platform, it is necessary to use peace The personal protective equipments such as full band, safety rope, prevent the generation of personnel's high fall accident.But due to not having above cable platform Component hangs safety belt, and staff can only hang over safety belt on platform, causes safety belt " height hangs low use ", runs counter to《State Family's grid company electric power safety working regulation》Requirement, serious personal safety hidden danger be present.How to ensure staff in electricity Safety when being worked on cable platform, turn into power worker's urgent problem to be solved.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of safe shaft tower cable platform work protection branch Frame.
In order to solve the above-mentioned technical problem, the utility model includes horizontally disposed cross-arm and the oblique branch being connected with cross-arm Support, the cross-arm are provided with multiple hanging points, and described bearing diagonal one end is hinged in the middle part of cross-arm, and the other end is provided with a link, in bar The side of tower and two connecting plates are correspondingly provided with up and down above the cable platform, wherein being additionally provided with connecting plate above One fix bar, the link of the bearing diagonal can be enclosed in fix bar, and the bearing diagonal and cross-arm are separately mounted to corresponding connect Fixed on fishplate bar and using bolt.
The distance between hanging point spaced set on the cross-arm and adjacent two hanging points are 20cm.
The cross-arm and bearing diagonal are made of angle steel or channel-section steel.
The fix bar includes the body of rod being vertically set on connecting plate and the baffle plate for being arranged on rod end, the bar Anti-slip veins are additionally provided with body.
The beneficial effects of the utility model are:The utility model forms triangle using cross-arm and bearing diagonal with shaft tower tower body Rock-steady structure, steadiness is strong, and the hanging point set on cross-arm is available for workmen to hang safety belt or safety rope, prevents personnel to be higher by Fall;And the requirement for being designed to meet multiple workmens while being constructed on cable platform of multiple hanging points;In addition, link Design with fix bar can play a part of auxiliary during installation and removal, be easy to dismount.
Brief description of the drawings
Fig. 1 is the main structure diagram of the utility model shaft tower cable platform work protective cradle;
Fig. 2 is that fix bar is arranged on the side structure schematic view on connecting plate in the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
Referring to Fig. 1 and Fig. 2, shaft tower cable platform work protective cradle of the present utility model includes horizontally disposed cross-arm 1 And the bearing diagonal 2 being connected with cross-arm 1, the cross-arm 1 are provided with multiple hanging points 3, described one end of bearing diagonal 2 is hinged on cross-arm 1 Middle part, the other end are provided with a link 4, and two connecting plates are correspondingly provided with up and down in the side of shaft tower 5 and above cable platform 6, wherein being additionally provided with a fix bar 7 on connecting plate 6 above, the link 4 of the bearing diagonal 2 can be enclosed in fix bar 7, The bearing diagonal 2 and cross-arm 1 are separately mounted to fix on corresponding connecting plate 6 and using bolt.
The distance between the spaced set of hanging point 3 on the cross-arm 1 and adjacent two hanging points 3 are 20cm.
The cross-arm 1 and bearing diagonal 2 are made of angle steel or channel-section steel.
The fix bar 7 includes the body of rod 71 being vertically set on connecting plate and the baffle plate for being arranged on the end of the body of rod 71 72, anti-slip veins are additionally provided with the body of rod 71.Such design can ensure the relative stability between fix bar 7 and link 4.And And link 4 is sleeved in fix bar 7, auxiliary can be played a part of during installation and removal, installation is laborsaving, is easy to tear open Dress.
The utility model is mainly used in, when cable platform installs cable accessory or maintenance, putting down during suitable for before circuit power transmission The safety guarantee to be worked on platform, after the completion of construction, this component is removed.
Protective cradle of the present utility model is arranged on shaft tower tower body, and is higher than 2 meters or so of cable platform, for constructor Member's suspension safety belt or safety rope, prevent personnel are higher by from falling.Cross-arm and bearing diagonal form triangle rock-steady structure with tower body, increase Add its steadiness, be wherein attached by bolt between cross-arm, bearing diagonal and tower body.One is set on cross-arm per 20cm Individual safety belt hanging point, the requirement for meeting multiple workmens while being constructed on cable platform.Shaft tower is pre- by producer in production The hanging point of protective cradle installation can be carried out by reserving, and be installed in tower erection, so as to the cable platform subsequently to carry out Annex installment work is prepared.After cable accessory installs, protective cradle can be removed, and transfer to run unit to take care of, Used when platform from now on overhauls.
In summary, content of the present utility model is not limited in the above embodiments, and those skilled in the art can To propose other embodiments within technological guidance's thought of the present utility model, but these embodiments are included in this practicality newly Within the scope of type.
