[ technical field ] A method for producing a semiconductor device
The utility model relates to a bridge engineering assists the apparatus field, concretely relates to light cat ladder that steel bridge welding used.
[ background of the invention ]
In recent years, steel structure bridges are increasingly applied to municipal highway engineering, and welding between steel structures is an inevitable link. The welding can be divided into according to the relative position of the space between the weldment of the welding seam: the flat welding, the vertical welding, the horizontal welding and the overhead welding are carried out, and construction operators need to weld different positions of the bridge member, and the upper part, the lower part and the upper part are inevitable.
The welding requirements of workers at different positions are traditionally realized through climbing ladders or specially-made steel structure climbing ladders with handrails from the ground. However, the ladder stand does not have handrails, so that the safety of the ladder stand is not guaranteed, and the steel-structure ladder stand with the handrails is too heavy and difficult to move. The ladder has the same defect that the ladder is required to be transferred through the ground, is often blocked by the ground obstacle and is difficult to pass through.
[ Utility model ] content
The to-be-solved technical problem of the utility model lies in providing a light cat ladder that steel bridge welding used, sets up its fixed point at steel construction bridge vertical and horizontal roof beam from top to bottom and realizes crawling, and can realize shifting on steel construction bridge, need not through ground transfer position, and it still has that overall structure is simple light, the installation is convenient, safe and reliable simultaneously to and improve work efficiency's advantage.
The utility model discloses a realize like this:
a portable crawling ladder for welding a steel bridge comprises a climbing ladder part, wherein vertical supports are arranged on two sides of the climbing ladder part;
the upper ends of the two vertical braces are respectively connected with a horizontally arranged top brace, and the two top braces are horizontally arranged; the free ends of the two top struts are provided with downward top clamping hooks;
one side of the bottom of the stair climbing part is connected with a horizontally arranged bottom support, and the direction of the bottom support is consistent with that of the top support; the bottom opposite side of stair portion is provided with the operation panel of level setting, the free end both sides of operation panel with it is provided with the bracing to connect between the top of the corresponding side erects the bracing of stair portion.
Furthermore, a reinforcing support is connected between the two top supports.
Furthermore, the bottom support and the adjacent end of the operating platform are connected with each other and integrally formed.
Furthermore, the middle part of the operating platform is of a connecting rod structure or a complete panel structure.
Furthermore, the portable ladder stand is formed by welding steel bars
The utility model has the advantages of:
the utility model discloses utilize steel structure bridge characteristics, design out a light cat ladder that steel bridge welding used, from top to bottom realize crawling its fixed point setting at steel structure bridge beam roof beam about freely and quickly, and can realize shifting on steel structure bridge, need not through ground shift position. In a word, the utility model has the advantages of simple and light overall structure, convenient, the safe and reliable of installation, can improve work efficiency, practice thrift the cost.
[ description of the drawings ]
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is the structure schematic diagram of the portable ladder used for welding the steel bridge of the utility model.
Fig. 2 is the utility model relates to a portable cat ladder and girder steel complex schematic diagram that steel bridge welding used.
[ detailed description ] embodiments
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings and the detailed description. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
