Summary of the invention
cause detecting constant to overhead electric power transmission transmission tower and easily producing the problem of potential safety hazard for lacking convenient ladder durable again in prior art, the embodiment of the present invention proposes one and is easy to operation and the simple electric power pylon of structure detects and uses detachable ladder.
to achieve these goals, the embodiment of the present invention puts forward the detection of a kind of electric power pylon and uses detachable ladder, comprises multiple cover connected components, pedestal, the top connector that can mutually be detachably connected;
wherein every suit connected components all comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, and described crosspiece is all perpendicular to described left support post and right support post; The top of wherein said left support post and right joint pin is provided with the joint pin extending described support column body, described connecting hole is provided with through hole perpendicular to axial direction, and bottom is provided with and the length of described joint pin and the suitable connecting hole of external diameter, and connecting hole is also provided with the through hole perpendicular to connecting hole axis, and the position of the through hole of the through hole of described connecting hole and described joint pin and internal diameter suitable;
wherein said pedestal comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, the top of wherein said left support post and right joint pin is provided with the joint pin extending described support column body, described connecting hole is provided with through hole perpendicular to axial direction, and bottom is provided with rubber earring moulding;
wherein said top connector comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, the top of wherein said left support post and right joint pin is provided with the crotch extending described support column body, and described crotch external surface is coated with rubber layer; And described joint pin, described connecting hole is provided with through hole perpendicular to axial direction.
wherein, the two ends of described crosspiece connect left support post, right support post by gusset, and are fixed by rivet.
wherein, also comprise connection hitching post, the aperture of the through hole of the external diameter of described connection hitching post and the through hole of described connecting hole, described joint pin is suitable.
wherein, one end of described connection hitching post is provided with rubber handle.
the invention has the beneficial effects as follows: the electric power pylon that technique scheme proposes detects and uses detachable ladder, the ladder of arbitrary height can be spliced into as required, and be fixed in overhead electric power transmission transmission tower by the top connector at top, there is sufficiently long distance on the ladder distance ground that overhead electric power transmission transmission tower so just can be made to carry, prevents other people from climbing.This ladder structure can be convenient to simply again dismounting simultaneously.
Accompanying drawing explanation
by the description carried out a preferred embodiment of the present invention below in conjunction with accompanying drawing, technical scheme of the present invention and technique effect thereof will become clearly, and more should be readily appreciated that.Wherein:
fig. 1 is the structural representation of the cover connected components of the embodiment of the present invention.
Detailed description of the invention
below with reference to appended accompanying drawing, a preferred embodiment of the present invention is described.
the embodiment of the present invention puts forward the detection of a kind of electric power pylon and uses detachable ladder, comprises multiple cover connected components, pedestal, the top connector that can mutually be detachably connected.Wherein, the structure of every suit connected components as shown in Figure 1, comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, and described crosspiece is all perpendicular to described left support post and right support post; The top of wherein said left support post and right joint pin is provided with the joint pin extending described support column body, described connecting hole is provided with through hole perpendicular to axial direction, and bottom is provided with and the length of described joint pin and the suitable connecting hole of external diameter, and connecting hole is also provided with the through hole perpendicular to connecting hole axis, and the position of the through hole of the through hole of described connecting hole and described joint pin and internal diameter suitable; Wherein said pedestal comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, the top of wherein said left support post and right joint pin is provided with the joint pin extending described support column body, described connecting hole is provided with through hole perpendicular to axial direction, and bottom is provided with rubber earring moulding; Wherein said top connector comprises left support post, right support post, is arranged at least two crosspieces be parallel to each other between two support columns, the top of wherein said left support post and right joint pin is provided with the crotch extending described support column body, and described crotch external surface is coated with rubber layer; And described joint pin, described connecting hole is provided with through hole perpendicular to axial direction.
