Description
Technical field
The present invention relates to ladder field, particularly relate to the mounting attachment of steel tube tower and the improvement of using method thereof.
Background technology
In order to be conducive to controlling of urban planning, the shaft tower that overhead wire is used in electric power facility, adopts steel tube tower to build usually.And when construction, consider that steel tube tower weight is large, by landform restriction, from factors such as the charged close together of bypass, often adopt the steel tube tower that only gin pole or crane merogenesis group are stood.Between adjacent two joint steel tube towers, adopt flange plate structure to connect, and interfixed by the uniform screw bolt and nut of a circle on flange.But, staff is when climbing up steel tube tower and installing screw bolt and nut, the staff limited length because steel tube tower diameter is comparatively large, when causing staff to stand in high-altitude erection bolt, staff cannot get at all bolt installation sites simultaneously, meanwhile, staff cannot change position again in the air easily at height.Therefore, when installing steel tube tower or overhauling, how can provide effective support to human body, can facilitate again, safety the high-level position of conversion human body become those skilled in the art's technical problem urgently to be resolved hurrily.
For the problems referred to above, traditional construction method can be following several usually:
One, outside steel tube tower, except the vertical cat ladder of routine, set up a pair symmetrically arranged auxiliary cat ladder, and auxiliary cat ladder is fixedly connected on the outer wall of steel tube tower; This type of auxiliary cat ladder using method is simple, and safety and reliability is high; But, if also also exist construction cost high, cannot use when overhauling old steel tube tower time steel tube tower diameter excessive (more than 10 meters) and still cannot get at the defects such as all bolt installation sites;
Two, carrying an annular safety rope by operating personnel and climb up vertical cat ladder, and be connected on flange by the top of safety rope, making operating personnel can step on safety rope by a pin when operating, a pin is stepped on vertical cat ladder and is installed bolt; But this type of safety rope is only applicable to the installation of the steel tube tower of minor diameter, Simultaneous Stabilization is poor, operation time security risk large;
Three, owing to being typically provided with reinforcing rib between bolt hole adjacent on flange, and reinforcing rib is typically provided with eyelet, therefore operating personnel can carry a mounting attachment and climb up steel tube tower, and by iron wire etc., mounting attachment is connected to below eyelet, thus operating personnel are stood on mounting attachment can install bolt; But operating personnel find in practice, this type of mounting attachment rocks comparatively large and mobile very inconvenience when work high above the ground, uses that operating efficiency is extremely low and construction effect is poor.
Therefore, above-mentioned three kinds of construction methods all cannot effectively solve can provide effective support to human body, can facilitate again, the problem of the high-level position of conversion human body of safety.In addition, in above-mentioned several construction method, operating personnel all stand in below and install the bolt more than crown, waste time and energy, and after installing, bolt very easily produces loosening, brings great potential safety hazard.
Summary of the invention
The present invention is directed to above problem, provide a kind of delicate structure, easy to use and use safety coefficient is high, good stability, effective support can be provided to human body, can facilitate again, safety the high-level position of conversion human body, be in mounting attachment and the using method thereof of the steel tube tower in below operating personnel chest when making bolt install simultaneously.
Technical scheme of the present invention is: the end face of described steel tube tower is provided with flange, and described flange is provided with the installing hole of some equally distributed bolts, and the below of adjacent described installing hole is provided with reinforcing rib, and described reinforcing rib is provided with eyelet; Described mounting attachment comprises flexible hanger and supporting ladder;
Described flexible hanger comprises a pair hanger and at least one slide track component; Described hanger top is provided with at least one pair of hook, and described in a pair, hook is rotatably connected on described hanger top; Described slide track component is located at described in a pair between hanger, and hanger described in a pair is slidably connected by slide track component;
Hanger described in a pair is divided into hanger one and hanger two, and described supporting ladder is fixedly connected on the side end face of described hanger one away from described hanger two.
Described slide track component comprises mutually adaptive arc shaped slider and arc chute;
The cross section of described arc shaped slider is in T shape and be fixedly connected on the end face of described hanger two, and described arc chute is T-slot and is fixedly connected on the end face of described hanger one; The length of described arc chute is greater than the width sum of hanger described in a pair.
Described slide track component comprises mutually adaptive arc fin and arc dovetail groove;
The cross section of described arc fin is trapezoidal and is fixedly connected on the end face of described hanger one, and described arc dovetail groove is fixedly connected on the end face of described hanger two; The length of described arc dovetail groove is greater than the width sum of hanger described in a pair.
