Description

Split type extension ladder

Technical Field

The utility model relates to the technical field of crawling ladders, in particular to a split type extension ladder.

Background

The wind generating set is generally installed in an area with good wind resources and generally consists of a cabin, a tower and an impeller; the wind power blows the impeller to rotate, a generator set in the engine room is driven to run to generate electricity, and the tower is used for supporting the engine room and the impeller; in order to ensure that the impeller is in an ideal angle with the wind direction all the time, the engine room can rotate according to the real-time wind direction to ensure that the impeller faces the wind.

The tower drum which plays a supporting role in the wind generating set and absorbs the vibration of the set is composed of a plurality of sections, the whole body is a cone, the lower part is large and the upper part is small, the lower part is connected with a fan foundation, and the upper part is connected with an engine room. Cabin inner space is narrow and small, and the overall arrangement is complicated, and integral extension ladder easily collides with the under-deck part at the actual installation in-process, needs an extension ladder easy to assemble, especially a split type extension ladder, can be with the extension ladder separation, in narrow and small space, safe convenient installation extension ladder.

Disclosure of Invention

The utility model aims to provide the wind power generator which is low in cost, simple in structure, strong in adaptability, better in structural strength, simpler in structure and easier to install, and can be better adapted to the wind power industry under the condition of severe working conditions of field use.

In order to achieve the aim, the utility model provides a split extension ladder, which comprises a fixed ladder, a movable ladder, a clip-shaped buckle and a rope, wherein the clip-shaped buckle is arranged at the top end of the fixed ladder; one end of the rope is fixed at the lower end of the fixed ladder, the rope upwards penetrates through the clip, the other end of the rope is fixed on the movable ladder, and the fixed ladder comprises an upper fixed ladder and a lower fixed ladder. When the movable ladder is used, the fixed ladder is fixed on the cabin through the double-headed bolts, and the rope is pulled to enable the movable ladder to move on the fixed ladder.

Optionally, the upper fixed ladder on the fixed ladder is connected with the connecting piece through a rivet.

Optionally, one end of the rope is fixed on the fixed ladder, and the other end of the rope is fixed on the movable ladder.

The utility model has the beneficial effects that:

1. the fixed ladder is divided into an upper fixed ladder and a lower fixed ladder, and the split type layout is easy to install in a narrow space;

2. the fixed ladder is fixed on the engine room through the double-headed bolt, so that the stability and the safety of the ladder stand are ensured.

Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships that, without particular explanation, are based on the orientations or positional relationships shown in the drawings only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 5, the present embodiment provides a split extension ladder, which includes a fixed ladder 1, a movable ladder 2, a movable ladder, a stud bolt 3, a clip 4, a rope 5, a lower fixed ladder 11, a connecting member 12, a rivet 13, and an upper fixed ladder 14. Fixed ladder 1 divide into fixed ladder 14 and fixed ladder 11 down, the type of returning detains 4 and installs on fixed ladder 1 top, the lower extreme of going up fixed ladder 14 passes through rivet 13 and links to each other with connecting piece 12, the one end of rope 5 is fixed on fixed ladder 1, passes the type of returning and detains 4, the other end is fixed on removing ladder 2, stud 3 installs on fixed ladder 1. When the movable ladder is installed, the upper fixed ladder 14 is inserted into the lower fixed ladder 11 through the connecting piece 12 on the upper fixed ladder to form the fixed ladder 1, the stud bolts 3 installed on the fixed ladder 1 are fixed with the engine room, when the movable ladder is used, the rope 5 is pulled to unlock the movable ladder 2, the movable ladder 2 slides downwards along the fixed ladder 1 until the telescopic ladder is completely extended, the movable ladder 2 stops sliding due to the pulling force of the rope 5, the extension of the telescopic ladder is completed, and at the moment, the movable ladder 2 reaches the working platform; when the telescopic ladder is folded, the rope 5 is pulled upwards, the movable ladder 2 slides upwards along the fixed ladder 1 until the movable ladder 2 reaches the locking position of the fixed ladder 1, and the telescopic ladder is folded.
