Abstract
The present invention discloses a kind of step ladder, including operating desk, and the operating desk is triangle, and three sides connect different ladders respectively, and each ladder is constituted by two support frames and some pedals being arranged between support frame, and three solars are provided with stopping means.Its operating desk includes fixed station and lifting platform, and ladder is connected with fixed station, and hydraulic pressure lifting device is provided between lifting platform and fixed station.The present invention have the advantages that simple in construction, stability it is good, using safe.
Description
Technical field
The present invention relates to ascending tool, more particularly to a kind of step ladder.
Background technology
The places such as the mountain ridge, hills, suburb being erected at transmission line of electricity, the economic trees such as willow, method paulownia are often planted in circuit protection channel by construction of line area peripheral edge peasant household, and the economic tree fast growth, height is high more.In order to ensure line security stable operation, line upkeep worker often needs to trim trees.Auxiliary is carried out commonly using step ladder in the process to remove obstacles work, operating personnel must stand and carry out tree trimming work using high handsaw on ladder.Original chevron shaped step ladder, is two to the contact point on ground during opening, and in the case of the injustice of ground, ladder easily tilts, it is necessary to which support staff is staircase.Ascend a height in operation process because ladder stabilizer is poor, handsaw operational security is poor, while branch fallen etc. easily injures the support staff of staircase by a crashing object.
The content of the invention
The purpose of the present invention is to overcome above-mentioned technological deficiency there is provided a kind of step ladder, and its stability is good, it is ensured that safety operation of the operating personnel on ladder;Without special messenger helping, the branch etc. that can avoid the occurrence of falling injures staircase by a crashing object person.
The technical solution adopted in the present invention is:A kind of step ladder, including operating desk, the operating desk are triangle, and three sides connect different ladders respectively, and each ladder is constituted by two support frames and some pedals being arranged between support frame, and three solars are provided with stopping means.
As a kind of preferred embodiment, stopping means is the equilateral triangle band of three ribbon compositions, and three angles of equilateral triangle band are connected to three ladders with the pedal of position.
As a kind of preferred embodiment, operating desk includes fixed station and lifting platform, and ladder is connected with fixed station, and hydraulic pressure lifting device is provided between lifting platform and fixed station.
As a kind of preferred embodiment, step ladder is made of aluminum alloy materials.
The step ladder of the present invention uses the structure of three face ladders, and the moulding similar to pyramid is formed after expansion, and its stability is good, and operating personnel's job safety type on ladder is high, and staircase is aided in without special messenger.Operating desk can be lifted, in the case of ladder insufficient height, can lifting operation platform, the requirement for height of satisfaction operation by hydraulic pressure lifting device.

Embodiment
Step ladder of the present invention, is made up of operating desk 1, three ladders 2 and stopping means 3, and operating desk 1 is triangle, and three sides connect different ladders respectively, and the connection between ladder 2 and operating desk 1 can be using modes such as gemel connections.Each ladder 2 is constituted by two support frames 21 and some pedals 22 being arranged between support frame, and three solars are provided with stopping means 3.
The equilateral triangle band that stopping means 3 in the present embodiment is made up of three ribbons, three angles of equilateral triangle band are connected to three ladders with the pedal of position.Equilateral triangle band can pull three ladders, prevent ladder from excessively opening.Equilateral triangle band drawing is balanced in power, simple in construction, convenient to install.
Operating desk 1 includes fixed station 11 and lifting platform 12, and ladder 2 is connected with fixed station 11, and hydraulic pressure lifting device 4 is provided between lifting platform 12 and fixed station 11.Fig. 4 be lifting platform 12 by the jack-up of hydraulic pressure lifting device 4, the structural representation separated with fixed station 11.Lifting platform 12 can be all mutually triangle or square, the circular configuration less than fixed station with the structure of fixed station 11.
The present invention have the advantages that simple in construction, stability it is good, using safe.
