Abstract

The invention relates to a quick combination ladder, wherein, the upper end and the lower end of a building window are combined with attaching clamps, a ladder and safety accessories and a set of combination ladder is arranged along the vertical direction of a building; a temporary passage is quickly formed in the direction needed for climbing, thereby not only trapped people can be rescued in time from a multistory building or a high-rise building but also fire-fighting rescue materials and equipment can be converted from the passage, and the fire-fighting rescue action in a fire scene where normal passages in the building are closed is made to be quick and convenient. The invention has the advantages of simple structure, convenient operation and safety and reliability, and is built in the fire scene where the normal passages in the building are closed and on the basis that other climbing devices can not be used. The invention is most suitable for middle and small cities where buildings are dense and climbing vehicles are in short supply.

Description

Quick assembling ladder

Affiliated technical field:

The present invention relates to a kind of quick assembling ladder, can't normally use, lack again under the situation that ladder truck or ladder truck can not normally use, set up an occasional passage fast at the interior of building passage.

Background technology

The domestic existing fire-fighting equipment of ascending a height has attic ladder at present, hook ladder, draw ladder and ladder truck, the longest 15 meters in three kinds of fire ladders, but it is very heavy, set up difficulty, almost successfully do not use at rescue site, therefore existing fire ladder is difficult to play a role in multilayer and high building fire fighting rescue action, and ladder truck is to environment for use, site requirements is very high, owing to ladder truck under the most of situation of the influence that is subjected to building periphery place and various overhead wires all can't use, cost an arm and a leg owing to ladder truck again, limited amount in each city nearly all is blank in the at county level and following cities and towns of One's name is legion.Therefore, the quick assembling ladder that can vertically set up along building is the important means of multilayer and high-rise building fire-fighting and rescue.

Three, quick assembling ladder comprises geometrical clamp, ladder and safety attachment three parts composition.

At present domestic still do not have like product and to the identification standard of whole combined system, and the rescue of ascending a height provides approach with regard to multilayer and high building fire fighting in the present invention.

Summary of the invention

The scheme that the present invention solves its technical problem is, successively fixing one from bottom to top along building window puts up a ladder, outside the building portion forms a vertical channel fast, realize the fire-fighting rescue of ascending a height, its embodiment is such: the up and down two ends of geometrical clamp at building window are fixed, the locking-type plug on the ladder is inserted in the bayonet socket of geometrical clamp down, movable plug is saved the appropriate location according to the height height of window, in the bayonet socket of geometrical clamp, ladder is fixed on the window in the insertion.

The specific embodiment

Wire rope (1) on the capstan winch (2) is unclamped, clamping plate (5) are adjusted to windowsill body of wall developed width, the windowsill body of wall was tentatively fixing about geometrical clamp (3) was snapped in.With the bayonet socket (6) on the geometrical clamp (3) under the insertion of the locking-type plug (7) on the ladder (9), movable plug (8) is adjusted to suitable height inserts the bayonet socket of going up on the geometrical clamp (3) (6), pull capstan winch (2) tense wire rope (1), ladder (9) is securely fixed on the window.After the levels ladder is fixing, the ladder overlapping part is fixed together, whole combination ladder is fused with buckle (9.6).

Personnel are connected safety hook (9.2) during ladder up and down with safe link on the self-contained safety belt of ascending stair personnel, grab the device (9.4) of restricting and move with personnel's easy on and off.In case when falling, it is locked at the tightrope correspondence position automatically to grab rope device (9.4), guarantees that the ascending stair personnel are perfectly safe.When being positioned at top dead centre or lower dead center, the rope device can make it get back to the position that the user of service needs when grabbing by messenger (9.1).

Claims

1. a quick assembling ladder is a fixed point with two ends about the building window, contains building window two ends ladder geometrical clamp, ladder and safety attachment three parts up and down.It is characterized in that: ladder is fixed on building window two ends up and down with geometrical clamp, begin successively upwards to set up from the bottom of building, form an occasional passage fast, when personnel climb up or down through ladder, self-contained safety belt can be connected with safety attachment on the ladder, guarantee personnel's being perfectly safe of ladder up and down.

2. quick assembling ladder according to claim 1 is characterized in that: the ladder geometrical clamp is made up of clip, wire rope, capstan winch, clamping plate, bayonet socket five parts.The circular arc of clip can adapt to the situation of the outstanding body of wall of part building window, leaves the body of wall certain distance so that climbing after making ladder fixing simultaneously.By regulating the length of steel wire on the capstan winch, can adapt to the requirement of different-thickness body of wall, by capstan winch geometrical clamp is securely fixed on the body of wall.

3. quick assembling ladder according to claim 1 is characterized in that: movable plug can be regulated at two side plate easy on and off of ladder, requires fast ladder to be fixed on the geometrical clamp according to the window of differing heights.

4. quick assembling ladder according to claim 1, it is characterized in that: safety attachment by be fixed on ladder up and down two ends safety rope, messenger and grab the rope device and form, grabbing the rope device links to each other by the self-contained safety belt hook of one section tightrope and hook and ascending stair personnel, grabbing the rope device can be with the activity of ascending stair personnel easy on and off, when falling, then can be fixed on moment certain any on.When grabbing the rope device when being positioned at top dead centre or lower dead center, can make by messenger and grab the rope device and get back to the needed position of user of service.

5. quick assembling ladder according to claim 1 is characterized in that: after floor set up up and down, overlapping part was together fixed by snap, and whole combination ladder is fused, and had further guaranteed the security reliability of combination ladder.
