The utility model can be installed and applied with the channel steel framework, which can effectively solve the ascending and hoisting problem in the field work; the utility model is equipped with the working platform, which ensures the working reliability of the worker; the enclosure rail not only is convenient to be dismounted, but also plays the safety roles which can not be attained through a common safety belt.
Description
Technical field:
The utility model relates to a kind of ladder, specifically a kind of ladder that is applicable to power system substation equipment maintenance and repair specialty usefulness.
Background technology:
The maintenance ladder of ascending a height for the GW-220kv isolating switch have many products to select in the market, but most product base adopts Corner Strapped, and structure is too complicated, and can not split, and brings very big inconvenience to carrying transportation; On the isolating switch that is meeting two ground cutter, fixedly the tending to of base conflicted mutually with ground cutter, waling stripe, makes the ladder of ascending a height can't normally fix use.In addition, 220KV disconnecting link current-carrying part is heavier, if the maintainer that ascends a height directly puts it to ground with hand or transmission rope, exists very big potential safety hazard.The patent No. is that 200520089514.5 Chinese patent discloses a kind of isolating switch maintenance special-purpose ladder, just the safety belt lock ring is set on the top of cleat stanchion, system is locked in the safety that guarantees the operating personnel in the safety belt lock ring with safety belt, but owing to adopted freestanding cleat stanchion, although have latch hook up and down, if want the fixed effect that reaches good, to the requirement of strength harshness of latch hook and cleat stanchion up and down.
The utility model content:
Technical problem to be solved in the utility model is exactly that a kind of 220kv is provided at above deficiency multi-functional maintenance ladder, and this ladder is in conjunction with the channel-section steel framework, and supporting capacity is strong, detachable, part-structure can fold, and it is extremely convenient to assemble, transport, and distinctive hoisting structure can lift by crane the weight of constant weight.
Technical solution adopted in the utility model is:
The multi-functional maintenance ladder of a kind of 220kv mainly is made of base and main ladder, wherein: have support on the base; Two cleat stanchions and crossbeam about main ladder comprises, cleat stanchion is connected on the support, has working platform between the crossbeam on cleat stanchion and top, also is provided with the fence of living and connecting on the cleat stanchion.
The middle part of base has elongated slot, and cross-under has fastening bolt in the elongated slot, in order to be connected and then firm banking with channel-section steel.
Cleat stanchion has insulated pipes used to make, and support is the projection that is fixed on the base, and the lower end of cleat stanchion is plugged on the support, and locks with pin.
One end of working platform is socketed on the crossbeam, and the other end of working platform is connected with cleat stanchion by the double link that rivet connects, and double link is free to rotate, and so just can reach working platform can be along the folded lengthwise of cleat stanchion.
Fence blocks for the U type encloses, and adopts thin aluminium-alloy pipe to make, and the fence two ends adopt pivot pin to be connected on the cleat stanchion, encloses to reach that block can be along the purpose of the folded lengthwise of cleat stanchion.
Also live on the cleat stanchion and be connected with the soft drawn rope, when the staff works, at the equipped soft drawn rope of the load-bearing dorsal part of cleat stanchion, to guarantee the security reliability of work.
Be socketed with hook on the cleat stanchion, and lock with pin for suppressing metal, the end of hook has been provided with Hanging roller, with the weight of slinging.
The beneficial effect that the utility model can reach is:
1, the utility model is the combined type framework, and part-structure can fold again, so fractionation, transportation and assembled on site are all extremely convenient.
2, the utility model can cooperate with the channel-section steel framework and installs and uses, and can effectively solve practical problems such as ascending a height of existing in the site work, lifting.
3, the utility model has been equipped with folding working platform, and at the equipped soft drawn rope of the load-bearing dorsal part of cleat stanchion, staff's functional reliability is protected; The U type encloses that block not only can be for convenience detach, and has played the inaccessible safety effect of half safety belt.
Whether 4, the distinctive hoisting structure of the utility model not only can be selected to install according to working condition, can lift by crane the general manual weight that can't transmit of people after the installation, and safe and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1: the base 2 of the multi-functional maintenance ladder of this 220kv adopts stainless steels, and base 2 middle parts are rectangle elongated slot 13, and elongated slot 13 is used for fastening decides bolt 3, and according to the width of framework channel-section steel 1, the width between two set bolts 3 can be adjusted immediately; Two set bolts, 3 belows are two blocks of little steel plates of cross-under respectively, in the time of fixedly, base 2 are placed on the channel-section steel 1, and two blocks of little steel plates are put into respectively in framework channel-section steel 1 groove, and it is fastening to go up lower steel plate with set bolt 3 then; Base 2 upper ends have the support 14 of projection formula, and cleat stanchion 5 is socketed on the support 14, and lock with pin 4; Has working platform 6 between the crossbeam 15 on cleat stanchion 5 and top, one end of working platform 6 is socketed on the crossbeam 15, the other end of working platform 6 is connected with cleat stanchion 5 by the double link 16 that rivet 8 connects, double link 16 is free to rotate, and so just can reach working platform 6 can be along the folded lengthwise of cleat stanchion 5; Cleat stanchion 5 is made by insulated pipes used, the upper end of cleat stanchion 5 also is provided with the fence 7 of living and connecting, and fence 7 blocks for the U type encloses, and adopts thin aluminium-alloy pipe to make, fence 7 two ends adopt pivot pin to be connected on the cleat stanchion 5, with reach enclose block 7 can be along the purpose of the folded lengthwise of cleat stanchion 5; Also be socketed with hook 10 on the cleat stanchion 5 wherein, and connect with pin for suppressing metal 9, the end of hook 10 has been provided with Hanging roller 11, with the weight of slinging, also live on the cleat stanchion and be connected with soft drawn rope 12, when the staff works, at the equipped soft drawn rope 12 of the load-bearing dorsal part of cleat stanchion 5, to guarantee the security reliability of work.
