Abstract
The utility model relates to a suspended type telescopic ladder, and belongs to the field of auxiliary devices for high-altitude operations. The suspended type telescopic ladder comprises a back ladder frame, a front ladder frame and a position-limiting mechanism, wherein support beams on the two sides of the back ladder frame are provided with inner slideways, the support beams on the two sides of the front ladder frame are provided with outer slideways, the back ladder frame is in sliding connection with the front ladder frame through the inner and the outer slideways, the position-limiting mechanism is arranged on the front ladder frame, the position-limiting mechanism comprises a main pin shaft, an auxiliary pin shaft, a clamping block and a stop block, the clamping block is in rotatable connection with the front ladder frame through the main pin shaft, the clamping block takes the shape of a curved hook, a jaw is arranged in the front of the curved hook, and a fixing pin is arranged at the upper end of the back ladder frame. A handle is arranged at the lower end of the front ladder frame, and pedals are respectively arranged on the front and the back ladder frames. The suspended type telescopic ladder disclosed by the utility model has the advantages of simple structure and easiness in operation; and as the suspension way is adopted, the limitations that the telescopic ladder can only be supported by the bottom and the ladder can not be pulled downwards for extending the ladder can be improved, and application places of the telescopic ladder become more extensive.
Description
Technical field
The utility model relates to the work high above the ground servicing unit.Be specifically related to a kind of suspension type extension ladder.
Background technology
Extension ladder is widely used in work high above the ground as common tool in the ascend operation, also ubiquity in the large-scale engineering machinery operation.Employed in the market extension ladder all is that the ladder lower end is supported, and extension ladder is upwardly extending then, needs to seek on the reliable supporting face; Supporting surface must be touched in the lower end of this kind ladder; Implement during the inconvenience special operation, especially when the device self that needs climbing need stretch adjustment, existing extension ladder used inconvenience especially; And existing extension ladder need be regulated ladder height, troublesome poeration through stay cord.
Summary of the invention
The purpose of the utility model provides a kind of suspension type extension ladder, to remedy the limitation that existing extension ladder can only lean on bottom support.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of suspension type extension ladder; Comprise back ladder, preceding ladder and position-limit mechanism; Be characterized in that the supported on both sides beam of said back ladder is provided with inner slide, the supported on both sides beam of said preceding ladder is provided with external slideway; Said back ladder and preceding ladder are slidingly connected through said inside and outside slideway, and said preceding ladder is provided with said position-limit mechanism.
Further; Said position-limit mechanism comprises stub axle, secondary bearing pin, fixture block and block; Said fixture block through the stub axle and said before ladder be rotatably connected, said fixture block is hook solid, ladder is fixedly the time; The claw of the front portion through crotch is connected with the pedal of front and back ladder, and the tail end of said crotch passes through secondary bearing pin and is connected with said block.
Further, the upper end of said back ladder is provided with steady pin.
Further, the lower end of said preceding ladder is provided with handle.
Further, be respectively equipped with pedal on the said forward and backward ladder.
The beneficial effect of the utility model is: the steady pin through ladder upper end, back can be suspended on high aerial, has avoided extension ladder in the prior art that the needs of bottom support face must be arranged, and makes that also the application of extension ladder is more extensive; Change the height of extension ladder through sliding in the slideway of ladder before the handle push-and-pull between preceding ladder and back ladder; Need to confirm to limit the slip between preceding ladder and the back ladder by position-limit mechanism behind the height; The position-limit mechanism of extension ladder is simple in structure, easy operating.

The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Arrive shown in Figure 5 like Fig. 1; A kind of suspension type extension ladder comprises back ladder 2, preceding ladder 3 and position-limit mechanism, is characterized in; The supported on both sides beam of said back ladder 2 is provided with inner slide; The supported on both sides beam of ladder 3 is provided with external slideway before said, and said back ladder 2 is slidingly connected through said inside and outside slideway with preceding ladder 3, and said preceding ladder 3 is provided with said position-limit mechanism.Said position-limit mechanism comprises stub axle 4, secondary bearing pin 7, fixture block 5 and block 6; Said fixture block 5 is rotatably connected through stub axle 4 and said preceding ladder 3; Said fixture block 5 is hook solid; Ladder is connected through the pedal of crotch place claw with the front and back ladder fixedly the time, and the tail end of said crotch passes through secondary bearing pin 7 and is connected with said block 6.The upper end of said back ladder 2 is provided with steady pin 1.The lower end of ladder 3 is provided with handle 8 before said.Be respectively equipped with pedal 9 on the said forward and backward ladder.
The operating principle of the utility model is following: on the position-limit mechanism shown in Figure 1 fixture block 5 can stop before ladder 3 the back ladder 2 on to lower slider.When upwards promoting handle 8; Position-limit mechanism is at the effect lower swing of back ladder 2 upper footboards 9; And then can be so that preceding ladder 3 slides smoothly; When fixture block on the position-limit mechanism 5 had just slipped over pedal 9, position-limit mechanism is swing naturally under the effect of self gravitation, if ladder 3 can be realized extension ladder carrying work before spurring downwards this moment again; Extend ladder if desired, pull handle 8 gets final product downwards, and this moment, block 6 was swung at the effect lower swing and the drive position-limit mechanism of pedal 9 together, the slip of ladder 3 on the ladder 2 of back before guaranteeing.If drop-down certain distance need stop, oppositely promoting, make fixture block 5 put pedal 9, and then the carrying work that pulls handle downwards and can realize extension ladder.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
