Technical field
The utility model relates to a kind of upkeep operation ladder, is applicable to the novel ladder of high-power transformer sleeve pipe.
Background technology
The 110kV transformer is common power transmission and transforming equipment, and sleeve pipe is its main accessories, is used for external lead wire support and insulation.Because the outer porcelain insulating creepage distance of sleeve pipe constantly increases; For guaranteeing the insulation and the anti-pollution flashover ability of sleeve pipe; Sleeve pipe exposes vertical height and also is increased to more than the 1.9m thereupon; In the monitoring test and service work of routine, when removing the lead-in wire termination, have following problem: 1, because the height of sleeve pipe, maintainer's point of must standing on tiptoe just can be disassembled work.2, the operator causes the activity duration to prolong the influence power supply because the semi-girder and the sharp operation easy fatigue of standing on tiptoe must be alleviated in the operation interval.3, owing to do not observe the back side of sleeve pipe top and lead-in wire connecting plate, operating personnel's instrument is placed not in place, is prone to make instrument to fall or the sleeve pipe of damaging, and influences repair quality.4, in order to observe sleeve pipe top situation, the maintainer stretches into sleeve pipe porcelain patticoat slit ascend operation with tiptoe, and slippage produces industrial accident easily.
The utility model content
The utility model technical problem to be solved provides a kind of bushing shell for transformer operation special-purpose ladder, has simple in structurely, and the characteristics of personal equipment breakdown are avoided in easy installation and removal,
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: bushing shell for transformer operation special-purpose ladder is characterized in that: comprise job platform, carriage and be connected the device of bushing shell for transformer; Said job platform is the flat board that a side has arc gap, and said carriage upper end is connected below the job platform, and said carriage is connected with the device that is connected bushing shell for transformer.
The further improvement that the utility model is done is: said carriage comprises two upright legs and crossbeam, and said crossbeam is connected between the upright leg, and said carriage is provided with connecting plate and is connected with the device that is connected bushing shell for transformer.The device of said connection bushing shell for transformer comprises soft anchor ear and binding strap; Said connecting plate is the rectangular slab that has hook, and said rectangular slab is separately fixed at the two ends up and down of two upright leg outer side faces, and said soft anchor ear is connected with hook through binding strap around bushing shell for transformer and at two ends.The device of said connection bushing shell for transformer comprises the spring steel band and the nut of two ends connecting bolt; Said connecting plate is for connecting the rectangular slab of angle bar; Said rectangular slab is separately fixed at the two ends up and down of two upright leg outer side faces; Said spring steel band is sleeved in the flexible protective casing, and said spring steel band passes bolts at two ends bolt hole on the angle bar of connecting plate and fastening by nut around bushing shell for transformer.Be provided with self-locking tension gear between said soft anchor ear and the binding strap.
Adopt the beneficial effect that technique scheme produced to be:
1, the ladder of ascending a height is not limited by the oil tank of transformer top duct, conveniently installs with sleeve pipe and combines firm.
2, the ladder height makes operating personnel's posture be in optimum state, is convenient to observe the raising repair quality.
3, terraced body adopts the epoxy resin material to be connected firmly, and is easy for installation.
4, strain self-locking device with gear, prevent the loosening unsafe factor that causes of soft anchor ear and binding strap.
5, job platform adopts the anti-on-slip of anti-skidding resin plate to fall.
6, simple in structure easy to use, raise labour efficiency, ensure personal device security.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the sterogram of installing and using of the utility model.
As shown in Figure 1: 1 bushing shell for transformer, 2 job platforms, 3 carriages, 4 soft anchor ears, 5 binding straps, 6 connecting plates, 7 hooks.
