Description

A kind of electric power extension type closes ladder

Technical field

Ladder is closed the present invention relates to a kind of electric power extension type, the conjunction ladder of special construction is specifically employed, employed Stretching structure closes ladder with a kind of of disc structure is stablized, and belongs to power maintenance tool field.

Background technology

When repairing or installing some power equipments, it is a kind of work that power domain staff is commonly used to close ladder Tool, because its working environment is complicated, do not fix, special requirement, such as power equipment maintaining is it is also proposed to the instrument that operator uses Personnel may in the wild carry out for a long time power equipment inspection or maintenance work at a distance, or not peaceful on some ground Conjunction is terraced, it is necessary to constantly employment is moved for steady local work, it requires that the conjunction ladder that work is used needs to be convenient for carrying, and reduces institute Take up space, can move well to save muscle power, Simultaneous Stabilization will get well, to ensure security, but at present on the market this Planting can be mostly that ladder length is fixed, it is not possible to adjust, and need artificial with telescopic and good stability conjunction ladder seldom Go to move and close moving back and forth for ladder, therefore in the urgent need to a kind of suitable power domain operating personnel use or fit up usually personnel The conjunction ladder for using.

The content of the invention

For above-mentioned deficiency, ladder is closed the invention provides a kind of electric power extension type.

The present invention is achieved by the following technical solutions：A kind of electric power extension type closes ladder, is closed by connecting shaft, first Section ladder, second joint ladder, the 3rd joint ladder, support column, fixing nut, stabilization disk, bolt, steady pin, threaded post, ten thousand Constituted to wheel, sliding block, horizontal ladder.

It is characterized in that：The top of the first joint ladder is provided with through hole, and two the first joint ladders are cut with scissors at top by connecting shaft It is connected together, the first joint ladder is terraced with second joint, and second joint ladder and the 3rd joint ladder are fixed on by bolt Together, the size of the 3rd joint ladder size terraced with second joint more than the first joint ladder, ladder, second joint ladder in the first joint Internal with the 3rd joint ladder to be provided with chute, horizontal ladder is fixedly connected with a slide block together, and sliding block can be slided in chute, sliding block and Connecting hole is all provided with first joint ladder, second joint ladder, the 3rd joint ladder, is linked together by steady pin, closed the 3rd The bottom for saving ladder is provided with screwed hole, and support column surface is designed with screw thread, and support column is coordinated installed in the 3rd joint ladder by screw thread Bottom, stabilization disk is fixedly mounted on support column bottom, and fixing nut is provided with above disk stablizing, and threaded post passes through screw thread Coordinate and be arranged on the 3rd joint ladder bottom, universal wheel is installed with below threaded post.

The usefulness of the invention is that a kind of electric power extension type closes ladder, in the form of three joint ladder combinations, due to The size of the 3rd joint ladder is maximum, second joint echelon it, so can easily twitch joint ladder after use, make the first pass Section ladder and corresponding the 3rd joint ladder that is placed on of second joint ladder are internal, realize the effect freely stretched, and can freely adjust conjunction Terraced height, while being all provided with chute in three joints ladder inside, sliding block can be moved freely in chute, therefore horizontal terraced and sliding The height of block can also be adjusted freely, and closing ladder can take out open steady pin after use, and horizontal ladder just can be under the drive of sliding block Moved freely in chute, all of horizontal ladder can be moved to all the bottommost of the 3rd joint ladder, save the space for closing ladder, side Portable belt, support column is provided with the bottommost for closing ladder, and wherein support column surface is designed with screw thread, can turn round support column It is dynamic just to adjust the height of stabilization disk, while stablizing fixing nut is installed above disk, by turning fixing nut Just stabilization disk can be fixed, wherein stable circular tray designs are concave shapeds into bottom, surface is designed with tongue and groove, and at it Skid resistant course is installed on surface, can keep stability in different ground, makes conjunction ladder safer when in use, while screw thread Column bottom is provided with universal wheel, by rotating the length of regulation threaded post and coordinating the length adjustment of support column, it is possible to achieve Operationally, stabilization disk landing, universal wheel is hanging, when mobile conjunction ladder is needed after work, universal wheel is landed, and makes to stablize circle Disk detachment ground, realizes the double effectses of the movement and security of closing ladder, therefore a kind of electric power extension type conjunction ladder can be real It is now free flexible, it is also possible to the position of horizontal ladder freely to be adjusted, while also achieving the effect that security is higher and is moved easily Really.

Brief description of the drawings

Accompanying drawing 1 is the structural representation of the present invention, and accompanying drawing 2 is unilateral ladder bed structure schematic diagram, and accompanying drawing 3 is the part of Fig. 1 Sectional view.
