Abstract
The utility model discloses a step ladder comprising a main body rod, one or more pedals parallel to and isolated from each other, and a handrail arranged at one side of the pedal(s), wherein the front end of the main body rod is provided with a clamping sleeve for fixing the step ladder, and the pedal(s) is/are arranged on the main body rod. The step ladder avoids the damage to segmented steel plates, can ensure the safety of an operator and is convenient for assembly and disassembly so that the operator can easily assemble, disassemble and carry the step ladder.
Description
Technical field
The utility model relates to a kind of ladder of marking time, particularly a kind of segmentation ladder of marking time.
Background technology
At present, in the shipbuilding operation, when the engineering staff need carry out operation in the segmentation that certain altitude is arranged, must rely on ladder segmentation up and down.The ladder of segmentation is divided into fixed and not fixed two classes about generally being used for.When adopting fixed ladder up and down during segmentation, be used for the hooking structure that ladder is fixed in the segmentation can be marked pit on the steel plate of segmentation, ladder itself also destroys the fillet of steel plate easily simultaneously; When adopting not fixed ladder up and down during segmentation, because ladder just leans on segmented edges, can't provide safeguard to the safety of operating worker, and ladder itself still scratches steel plate easily, these all can cause the damage to the segmentation steel plate, thereby have reduced the quality of segmentation.
The utility model content
The technical problems to be solved in the utility model is to damage the defective of steel plate easily in order to overcome prior art, and a kind of segmentation that can not damage steel plate ladder of marking time is provided.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of ladder of marking time, and its characteristics are that it comprises: a main body bar, its front end are provided with one and are used for fixing this terraced chucking cover of marking time; One or more being parallel to each other and the pedal of space is located on this main body bar; One handrail is located at a side of this pedal.
Wherein, this chucking cover comprises: a upper steel plate that is parallel to each other and a lower steel plate, and this lower steel plate is provided with a bolt hole; One bolt that cooperates with this bolt hole.
Wherein, this main body bar is a steel pipe.
Wherein, this pedal plane is made of the many steel bars that are arranged in parallel.
Positive progressive effect of the present utility model is: the ladder of marking time of the present utility model is guaranteeing to be made on the basis of industry personnel basic function up and down, avoided in use damage to the segmentation steel plate, and can ensure operating personnel's safety, in addition, this ladder of marking time is simple in structure, easy accessibility makes the operating personnel easily to carry out dismounting and carrying to it.

Fig. 2 is the elevation of the ladder of marking time of the present utility model.
Fig. 3 is the vertical view of the ladder of marking time of the present utility model.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the ladder of marking time of the present utility model comprises: a main body bar 1 that plays the main support effect, this main body bar 1 is a steel pipe in the present embodiment, and the front end of this main body bar 1 is provided with a chucking that is used for fixing this ladder of marking time and overlaps 2, and this chucking cover 2 is used for when needs use this to mark time ladder this ladder of marking time being fixed in the steel plate of segmented edges; This ladder of marking time also comprises one or more being parallel to each other and the pedal 3 of the steplength that space one is suitable, be provided with 2 pedals 3 in the present embodiment, pedal 3 is fixed on this main body bar 1 and with this main body bar 1 and is certain inclination angle, with guarantee chucking when main body bar 1 overlap 2 be fixed on the steel plate of segmented edges after, these one or more pedals 3 are horizontal level, trample for the operating personnel; This ladder of marking time also comprises a handrail 4 that vertically is provided with, and this handrail 4 is positioned at a side of pedal 3, and this handrail 4 is arranged at the left side of a pedal 3 at place, higher position in the present embodiment.
Wherein, as shown in Figure 1, this chucking cover 2 comprises: a upper steel plate 5 that is parallel to each other and a lower steel plate 6, and this lower steel plate 6 is provided with a bolt hole; An and bolt 7 that cooperates with this bolt hole.When needs use this to mark time ladder, unclamp bolt 7 earlier, the steel plate at segmented edges place is pressed from both sides between this upper steel plate 5 and lower steel plate 6, and then screw steel plate and the upper steel plate 5 that this bolt 7 compresses the segmented edges place, be anchored on the steel plate at this segmented edges place with ladder that this is marked time; And when no longer needing to use this to mark time ladder, as long as just unclamp this bolt 7 and can easily the ladder of marking time be removed.
In addition, in order to alleviate the weight of the whole ladder of marking time, with convenient carrying, the pedal plane of pedal 3 is not a solid steel plate, but adopts the many steel bars that are arranged in parallel 8 to constitute, as shown in Figure 3.
In sum, the ladder of marking time of the present utility model is guaranteeing to be made on the basis of industry personnel basic function up and down, owing to adopted the method that is fixedly clamped, avoided in use damage, and can ensure operating personnel's safety, in addition the segmentation steel plate, this ladder of marking time is simple in structure, easy accessibility, weight is light, makes the operating personnel easily to carry out dismounting and carrying to it.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
