Specifically, the upper end of the first ladder 1 or the second ladder 2 is provided with a lighting device 4. In the present embodiment, the lighting device 4 is provided at the upper end of the first ladder 1. Through setting up lighting device 4, when the maintenance environment was darker, lighting device 4 can provide the light source for the maintenance personal, has guaranteed that maintenance work can normally go on.

Specifically, the lighting device 4 includes a ratchet seat 401, a universal tube 402 and a lighting lamp 404, in this embodiment, one end of the universal tube 402 is connected to the first ladder 1 through the ratchet seat 401, in other embodiments, the ratchet seat 401 may also be connected to the second ladder 2, and the other end of the universal tube 402 is connected to the lighting lamp 404. The maintenance personnel can rotate the ratchet seat 401 and twist the universal tube 402 to adjust the illumination direction of the illuminating lamp 404, so that convenience can be further provided for the maintenance personnel by arranging the ratchet seat 401 and the universal tube 402.

Specifically, the lighting device 4 further includes a fixing base 403, one end of the universal tube 402 close to the lighting lamp 404 is fixedly connected to the fixing base 403, and the fixing base 403 is detachably connected to the lighting lamp 404. Through setting up fixing base 403 and can dismantle with light 404 and be connected, when light 404 appears damaging, can change light 404 alone to the cost of maintenance that realizes reducing the engineering ladder.

Specifically, in this embodiment, a storage device 5 is further disposed between the first ladder 1 and the second ladder 2, and two sides of the storage device 5 are respectively connected to the first ladder 1 and the second ladder 2. A plurality of maintenance tools are needed during maintenance, and the storage device 5 is arranged, so that a temporary storage point can be provided for the maintenance tools during maintenance, and maintenance personnel can conveniently take and use the maintenance tools; after the use, the maintenance tool can be put back into the storage device 5, so that the condition that the maintenance tool is lost due to improper storage is avoided.

Specifically, storage device 5 includes folding box 501, and box 501 includes that the second holds chamber and second opening, and the second opening holds chamber and outside intercommunication with the second, and box 501 is close to a set of parallel both sides limit of second opening and is provided with axis of rotation and overlap joint position 502 respectively, and box 501 is articulated through axis of rotation and second ladder 2, and first ladder 1 is provided with the overlap joint pole of cooperation overlap joint position 502, during the use, takes overlap joint position 502 in the top of overlap joint pole. Because connect through articulated mode between first ladder 1 and the second ladder 2, when the engineering ladder need not use, can rotate first ladder 1 and second ladder 2 to the laminating and conveniently accomodate, and storage device 5 sets up between first ladder 1 and second ladder 2, at this moment, through setting up overlap joint position 502, overlap joint pole and folding box 501, when the engineering ladder finishes using and needs folding accomodating, box 501 can accomodate together along with the engineering ladder, need not take off from the engineering ladder and place in addition, avoided box 501 to take place because of depositing the improper phenomenon of losing.

Preferably, in this embodiment, the material of the box body 501 may be cloth, and may also be other flexible materials, in other embodiments, the box body 501 may also be formed by combining a plurality of rigid plates, the plurality of rigid plates are hinged, and when the box body 501 needs to be stored, the storage box may be folded and stored according to a certain folding manner.

Specifically, because the first ladder 1 and the second ladder 2 are connected in a hinged manner, when a maintenance worker uses the engineering ladder to perform climbing operation, under the action of gravity, an included angle between the first ladder 1 and the second ladder 2 always tends to increase, in the embodiment, non-end areas of the first ladder 1 and the second ladder 2 are respectively connected through two ends of a connecting belt 7, and by arranging the connecting belt 7, partial gravity component force can be offset, so that the engineering ladder is prevented from being damaged due to an overlarge included angle formed between the first ladder 1 and the second ladder 2, and the service life of the engineering ladder is prolonged; the connecting band 7 has formed the triangle-shaped structure with being between the first ladder 1 and the second ladder 2 of contained angle, and the triangle-shaped structure is firm, consequently sets up connecting band 7 and can further improve the stability of engineering ladder, has ensured the security that maintenance personal ascended a height the operation.

Specifically, the connecting belt 7 may have an elastic tension belt, and when the tension belt is stretched, the elastic force of the tension belt may offset a part of the gravity component, thereby preventing the engineering ladder from being damaged and improving the service life of the engineering ladder.

Certainly, under the maintenance environment of difference, need adjust the contained angle size between first ladder 1 and the second ladder 2 in order to adapt to different service environment, consequently, can set up adjustable length's connecting band 7 and connect first ladder 1 and second ladder 2, when using, can adjust the angle of first ladder 1 and second ladder 2 earlier, then adjust the length of connecting band 7, make connecting band 7 be in by tensile state, like this, the tension of connecting band 7 can offset partial gravity component, thereby avoid the damage of engineering ladder, the life of engineering ladder has been improved. Through the connecting band 7 that sets up adjustable length, can improve the application scope of engineering ladder, further provide convenient for maintenance personal.

Specifically, the bottom ends of the first ladder 1 and the second ladder 2 are both provided with anti-slip devices. Because the maintenance environment is changeable and unpredictable, the ground of partial maintenance environment is more smooth, and the focus is higher when maintenance personal ascends the operation, and stability is relatively poor, through setting up antiskid, can increase the frictional force between engineering ladder and the ground to avoid the engineering ladder to appear skidding, improved the security of maintenance personal operation.

Specifically, antiskid is antiskid 6, and the bottom of first ladder 1 and second ladder 2 is provided with through-hole 8, and antiskid 6 is provided with through-hole 8 articulated complex hinge bar 601. Because the contained angle between first ladder 1 and the second ladder 2 is adjustable, when changing the contained angle size between first ladder 1 and the second ladder 2, the angle of skid-proof base 6 can carry out adaptability ground adjustment, stability when improving the engineering ladder and using.
