Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
The utility model high-altitude maintenance operating ladder fixed structure, as shown in Figure 1, this ladder 1 is made up of the vertical rod of both sides and the cross bar be located at as ladder between two vertical rods, two vertical rod upper ends are equipped with downward arc linkage section 11, the straight inserting section 12 with spliced eye is connected in the lower end of arc linkage section 11, fixed mount 2 is provided with the inserting column 22 be connected with spliced eye in straight inserting section 12, and fixed mount 2 need overhaul transformer upper cover edge by dismountable being fixed on of clamping device 23.This kind of fixed structure, install fixed ladder firm, safety is high, is particularly useful for the special status of transformer high-altitude maintenance.
In the utility model, a kind of embodiment provided, being fixedly connected with for ease of fixed mount, the structure of fixed mount 2 as shown in Figure 2, fixed mount 2 comprises support 21 and provided thereon to be fixedly clamped at the clamping device 23 at transformer edge, support 21 is also provided with the inserting column 22 coordinating grafting with spliced eye stretched out.The U-shaped frame of support 21 for being sidelong, clamping device 23 is located on the side arm of support 21, and a side arm end of U-shaped frame is provided with threaded guide sleeve 211, and screw rod 232 can along fairlead 211 free adjustment height, another side arm of U-shaped frame is provided with the fixture block 212 of plane, to increase clamping area.Clamping device 23 comprises the screw rod 232 coordinating up-down adjustment with threaded guide sleeve 211, controls the distance between fixture block 212 by adjusting screw(rod) 232.By can free adjustment clamping device 23 to clamp the head cover of transformer edge of different-thickness, realize the fixing of fixed mount 2.In order to play anti-skidding effect, skidding 233 of can setting up defences in screw rod 232 one end be placed in inside U-shaped frame, the other end is provided with the adjustment disk 231 controlling screw rod 232 and move, so that regulate manipulation screw rod 232.Preferably, slipmat 233 is rubber pad.U-shaped support 21 is stuck in transformer edge, and adjusting screw(rod) 232 makes it coordinate with fixture block 212 to be fixedly clamped up and down, is plugged on inserting column 22 by the spliced eye 113 of ladder upper end, plays fixing effect after fixing.Unclamping fixed mount 2 can shift position easily, is applicable to multiple occasion of not easily placing fixed ladder, after finishing using, unclamps the screw rod 232 of clamping device 23.
Fixed mount 2 is provided with two, corresponding respectively with two spliced eyes in two straight inserting section 12.Connected by connection cord 4 between two fixed mounts 2, lose when avoiding placing at ordinary times.The stretching length of connection cord 4 level ensures that the center to center distance between two inserting columns 22 is identical with the center to center distance between two spliced eyes, after only needing arbitrarily to fix a fixed mount 2, stretching connection cord 4 is another required fixing position of fixed mount 2, be convenient to install and connect, avoid because permanent position deviation causes being difficult to the problem of corresponding grafting.
The lower end of this ladder 1 liang of vertical rod is equipped with the spliced eye coordinated with inserting column 22.During use, after maintainer utilizes this operating ladder to climb transformer top, can turn round and ladder is smoothly up put forward, then the spliced eye of ladder 1 bottom is inserted on the inserting column 22 on two fixed mounts 2 originally, can be used for maintainer to fix safety belt after fixing to use, can to hang on corresponding ladder cross bar by height difference according to working site situation and regulate.Maintainer using on safety belt efficiently bolt hanging ladder as the strong point, utilize this covering device effectively can solve the security hidden trouble preventing high pendant in puzzlement maintainer Repair of Transformer process for many years, ensure the safety of maintainer.
In order to alleviate the weight of ladder, be easy to carry use, and vertical rod and the cross bar of preferred formation ladder 1 are hollow section, are convenient to grafting simultaneously and install fixing.Selecting of hollow section may the rear supporting capacity of high pendant design according to maintainer, and leaves certain nargin, ensures safety.
Use in transformer station because considering this work high above the ground maintenance ladder being many, preferred ladder skeleton 1 is made up of isolation material or is wound around on ladder 1 edge and covers one deck insulating tape.A cross bar of top is wound around the eye-catching red adhesive tape of color, plays warning and prevent from stepping on empty prompting operation.
The pallet 3 on transformer body is being supported near ladder 1 lower end.This pallet 3 is rotatable foldable structure, and pallet 3 is rotating to be articulated with in vertical rod, and another side supports restriction pallet 3 by the stay cord be connected on ladder 1 and rotates stop.When maintainer utilizes this step ladder to climb the large lid of transformer top, ladder can be picked up lower end is fixed on fixed mount, open pallet 3, pallet 3 both sides stay cord is fixed, ensure that it is vertical with the relative position of ladder 1 or slightly to the certain angle that has a down dip, maintenance tool is placed wherein, forgets after also preventing from while conveniently taking overhaul and take away, really accomplish that work is complete, expect only, place is clear.Upwards can rotate time not no at ordinary times and pack up, the size of pallet 3 is set in the framework that can just pack up and surround to ladder vertical rod and cross bar, and space-saving other functions that also do not affect normally use.Simultaneously, when step ladder, pallet 3 can also play certain supporting role, pull out this pallet 3, make its top on transformer body, ladder 1 upper end is fixed by two fixed mounts 2, the supporting role of auxiliary tray 3 again, form the stability of gusseted, the object done like this prevents ladder from rocking back and forth when ascending a height and climbing transformer body, to increase the stability of itself.Can to set up defences in pallet one end and transformer contact position sliding rubber sheet gasket, to strengthen stability further, improve the safety factor of the work of ascending stair people.
The utility model high-altitude maintenance operating ladder fixed structure, ladder 1, by being connected with fixing fixed mount 2 on the transformer, guarantees stable the fixing of ladder 1, safe and reliable; Detachable fixed mount 2 realizes moving freely position at enough job areas; The clamping device 23 of adjustable gripping is applicable to the transformer upper cover clamping different-thickness, easy to use, fixed; After climbing up eminence, can ladder 1 lower end grafting be fixed on fixed mount 2, maintainer can using on safety belt efficiently bolt hanging ladder as the strong point, utilize this fixed structure effectively can solve the security hidden trouble preventing high pendant in puzzlement maintainer Repair of Transformer process for many years; This high-altitude maintenance operating ladder fixed structure has safety, applicability, fixes the plurality of advantages such as simple and reliable, easy to carry, the safety of maintainer in transformer top maintenance process is greatly enhanced, has stronger practicality.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of various unsubstantialities that method of the present utility model design and technical scheme carry out or directly apply to other occasion, all within protection domain of the present utility model.
