Description
Technical field
The utility model is related to ladder field, more particularly to the mounting attachment of steel tube tower is improved.
Background technology
In order to be conducive to controlling for urban planning, the shaft tower in electric power facility used by overhead transmission line, generally using steel pipe
Tower is built.And in construction, it is contemplated that steel tube tower weight is big, is limited by landform, from the powered factor such as closer to the distance of bypass,
Frequently with the vertical steel tube tower of only gin pole or crane merogenesis group.Connected using flange plate structure between two adjacent section steel tube towers,
And interfixed by the uniform screw bolt and nut of the circle on ring flange.However, staff is climbing up steel tube tower pair
When screw bolt and nut is installed, the staff limited length because steel tube tower is relatively large in diameter causes operator station to pacify in high-altitude
Staff cannot simultaneously get at all of bolt installation site during dress bolt, meanwhile, staff in the air again cannot be convenient in height
Change position.Therefore, when being installed to steel tube tower or being overhauled, how can give people body and effectively support, and energy side are provided
Just, the safe high-level position of conversion human body becomes those skilled in the art's technical problem urgently to be resolved hurrily.
For the problems referred to above, traditional construction method generally can be following several：
First, a pair symmetrically arranged auxiliary cat ladders are set up in addition to conventional vertical cat ladder outward in steel tube tower, and will auxiliary
Cat ladder is fixedly connected on the outer wall of steel tube tower；Such auxiliary cat ladder using method is simple, and safety and reliability is high；However,
If there is also that construction cost is high, cannot use when overhauling to old steel tube tower, steel tube tower diameter it is excessive（More than 10 meters）
When still cannot get at the defects such as all of bolt installation site；
2nd, carry an annular safety rope by operating personnel and climb up vertical cat ladder, and flange will be connected at the top of safety rope
On disk so that operating personnel in operation can a pin step on safety rope, a pin steps on vertical cat ladder and bolt is installed；So
And, such safety rope is only applicable to the installation of the steel tube tower of minor diameter, Simultaneous Stabilization is poor, operation when security risk it is big；
3rd, due to being typically provided with reinforcement between bolt hole adjacent on ring flange, and eyelet is typically provided with reinforcement,
Therefore operating personnel can carry a mounting attachment and climb up steel tube tower, and mounting attachment is connected to into eyelet lower section by iron wire etc., so as to
So that standing can be installed on mounting attachment to bolt；However, operating personnel are in practice, it has been found that such auxiliary
Ladder rocks larger and mobile extremely inconvenience in 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 cannot effectively solve that body offer effectively support, and energy side can be given people
The problem of just, the safe high-level position of conversion human body.Additionally, in above-mentioned several construction methods, operating personnel stand under
Side installs to the bolt more than crown, wastes time and energy, and installation rear bolt easily produces loosening, brings great safety
Hidden danger.
In this regard, State Bureau disclose on March 25th, 2015 a entitled " a kind of mounting attachment using method of steel tube tower ",
The Chinese invention patent of Application No. " 201310260307.0 ", however, people have found after actually used, such technical scheme
Prior to opening up eyelet on the reinforcement of the lower section of ring flange, therefore certain volume must be brought in the manufacturing cost of ring flange
Outer increase, and cause the mounting attachment of such steel tube tower that there is great defect in versatility.
Utility model content
The utility model is directed to problem above, there is provided a kind of delicate structure, easy to use and high, steady using safety coefficient
It is qualitative good, on the premise of ring flange original structure is not changed, body can be given people effectively support is provided, and can convenient, safety
The high-level position of conversion human body, while so that bolt is in the auxiliary of steel tube tower below operating personnel chest when installing
Ladder.
The technical solution of the utility model is：For the abutting joint of steel tube tower upper flange plate, the ring flange is located at steel
On the end face of pipe tower and ring flange is provided with the installing hole of some equally distributed bolts, the lower section of the ring flange is fixed and is connected
Connect and be evenly equipped with some reinforcements；The mounting attachment includes flexible hanger and supporting ladder；

It is in below operating personnel chest, is easy to operating personnel to have an effect.
The bottom of linkage section 222 of the supporting ladder 22 is provided with an at least strut 223, and the strut 223 is expansion link, described
Strut 223 is connected with horizontally disposed pulley 1 away from one end of the supporting ladder 22；So, the length of strut can be done
Go out adaptability regulation so that in the steel tube tower for different size, pulley one can effectively prop up the outer of steel tube tower for this case
Wall.On the one hand, the bottom to supporting ladder provides effectively support, improves overall stability and intensity；On the other hand, keep away
Exempted from supporting ladder to be directly fitted on the outer wall of steel tube tower, left sufficiently large human users space, improve it is overall can
Operability and usability.
The top of the support section of the supporting ladder 22 is provided with an at least jury strut 224, the jury strut 224 away from
One end of support ladder 22 has been threaded connection connecting rod, and the bottom of the connecting rod is connected with the pulley 2 2240 being vertically arranged.
So, the height that pulley two is located can easily be adjusted so as to the top of the ring flange of upside can be fitted in when in use
On face, so that while pulley one, pulley two integrally play the guiding role to supporting ladder, making with a certain degree of support
With.
The first embodiment of slide track component in the utility model, the slide track component 213 includes the arc being mutually adapted
Shape slide block 2131 and arc chute 2132；The section of the arc shaped slider 2131 is in T shape and is fixedly connected on the hanger two
On 212 end face, the arc chute 2132 is T-slot and is fixedly connected on the end face of the hanger 1.
Second embodiment of slide track component in the utility model, the slide track component 213 includes the arc being mutually adapted
Shape fin and arc dovetail groove；
The section of the arc fin is trapezoidal and is fixedly connected on the end face of the hanger one, the arc dovetail
Groove is fixedly connected on the end face of the hanger two.
The strap 215 towards ambulatory splint 216 end face and ambulatory splint 216 towards strap 215 end
Slipmat is fixedly connected with face, the slipmat is serrated or wavy.
Use according to the following steps, as shown in Fig. 9-14：
1）, mounting：Manually mounting attachment is hung on ring flange, and the height of the length to strut and pulley two is adjusted
Section so that mounting attachment is stable to be articulated on ring flange；
