Detailed Description

In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides embodiments or examples to implement the structures of the present invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the utility model. The terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the utility model and for simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the utility model. 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 should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 to 4 show an embodiment of the utility model, and as shown in the drawing, a crane boom comprises a bottom rod 1, a top rod 2 and a connecting rod group 3, wherein the bottom rod 1 is U-shaped, the insides of the bottom rod 1 are connected through a cross rod 4, the top rod 2 is arranged in the center of the upper part of the bottom rod, the top rod 2 is connected with the bottom rod 1 through the connecting rod group 3, the crane boom further comprises a support rod 5, a bottom frame 6, a guardrail 7 and a guard rod 8, the bottom of the outer side of the bottom rod 1 is connected with the bottom frame 6 through the support rod 5, the guardrail 7 is vertically arranged on the bottom frame 6, the top of the guardrail 7 is connected with the guard rod 8 through a plurality of groups of short rods 9, and a plurality of groups of limiting bulges 10 are uniformly arranged on the guard rod 8.

By arranging the support rod 5 and the bottom frame 6, an overhaul channel can be provided for operators to walk; by arranging the guardrail 7, the maintainers can hold the guardrail, so that the safety of the maintainers is improved, and the risk of accidental falling of the maintainers is reduced; by arranging the protective rod 8, a maintainer can hang a safety rope in a sleeving manner, so that the safety is improved; through setting up spacing arch 10, can hang aloft and when upwards climbing at the maintainer, spacing safety rope makes safety rope fixed position, prevents that safety rope from sliding.

The distance between the support rods 5 is 0-200 mm. Be 0 ~ 200mm through setting up the interval between each bracing piece 5, can guarantee that the maintainer can step on many bracing pieces 5 simultaneously, improve the stability of trampling.

The distance between the short rods 9 is larger than or equal to the distance between the railings of the guardrail 7. Through setting up the interval of 7 railings of interval more than or equal to guardrail between the quarter butt 9, can reduce the maintainer and dismantle the number of times of hanging the safety rope when guaranteeing that guard bar 8 is stable firm.

The limiting protrusions 10 are arranged on the inner side of the guard bar 8 in an obliquely upward mode, and the distance between every two limiting protrusions 10 is 0-100 mm. Through setting up spacing arch 10 in the inboard oblique top of protective rod 8, make spacing arch 10 only produce the effect when the maintainer accident falls, can not hinder the removal of safety rope when normally walking in guardrail 7.

The supporting rod 5 is provided with a protective net 11, and the protective net 11 is arranged between the bottom rod 1 and the bottom frame 6. Through setting up protection network 11, can further improve the stability that the maintainer stepped on, prevent to step on empty.

When the safety rope is used, firstly, a first safety rope is hung on the protection rod 8 by a maintainer, then the guardrail can hold the guardrail 7 and walk on the protection net 11 supported by the support rod 5, because the maintainer walks on the inner side of the protection rod 8, the outer side of the safety rope slides on the protection rod 8, the inner side of the safety rope cannot be in contact with the limiting bulge 10 on the inner side of the protection rod 8, namely the limiting bulge 10 cannot obstruct the normal sliding of the safety rope, the protection net 11 can provide stable friction for the maintainer, the maintainer is prevented from skidding when walking, and the guardrail 7 can protect the maintainer and prevent the maintainer from accidentally falling; along with the forward overhaul of the maintainer, the safety rope slides on the protective rod 8 along with the maintainer until the safety rope touches the short rod 9, the maintainer firstly sleeves and hangs a second safety rope on the protective rod 8 on the other side of the short rod 9, and then the first safety rope is detached so as to continue to move forwards; when the maintenance personnel accidentally fall, the maintenance personnel are hung in the air, the safety rope on the inner side is tightly attached to the inner side of the protection rod 8, the safety rope can be limited by the limiting bulge 10 in the process that the maintenance personnel shake in the air and climb upwards, the safety rope is prevented from moving greatly and even not moving, the maintenance personnel can stably borrow the safety rope and quickly return to the protective net 11 on the inner side of the guardrail 7, the safety rope protection device can not only facilitate the maintenance personnel to maintain the crane boom of the crane, but also prevent the safety rope from shifting when the maintenance personnel accidentally fall and climb upwards, and the safety of the maintenance personnel is effectively protected.

Although the present invention has been described with reference to the specific embodiments shown in the drawings, it is not intended to limit the scope of the present invention, and various modifications and variations can be made by those skilled in the art without inventive changes based on the technical solution of the present invention.
