Abstract
The utility model provides a glass fiber reinforced plastics insulating ladder, which includes four support bars. A support plate is fixed on the top end of the support bar, each support bar consists of an air-core FRP liner and a plastic layer which coats the periphery of the air-core FRP liner, the support bar has an open hole, a plastic brace is fixed between every two support bars and two sides of the plastic support brace are fixed in the hole. The utility model makes the insulating ladder using the FRP and plastic, and has advantages of no damage to human body by long-term using and high wear resistance, the guarantee of insulation as well, etc. .
Description
Technical field
The utility model relates to the insulation utensil, is a kind of glass fibre reinforced plastic insulating stepladder.
Background technology
Insulating ladder normally is coated with insulating layer outside metal, this insulating layer is as slight crack occurring or when coming off, electric shock accidents takes place easily, so the most of at present glass fibre reinforced plastic insulating stepladder that uses in this area.But the deficiency of this insulating ladder is: after using a period of time, the outer wearing and tearing of glass fiber reinforced plastic easily make glass fiber expose the skin of harm people, cause phenomenon allergic, that itch comparatively serious, up-to-date report glass fiber is easily carcinogenic, and therefore, many enterprises transfer to select the metal-insulator ladder.
Summary of the invention
The purpose of this utility model is, a kind of glass fibre reinforced plastic insulating stepladder is provided, and adopts glass fiber reinforced plastic and plastics to make insulating ladder, when guaranteeing insulation, makes it have long-term use and human body do not produced damage etc., and make it have the good advantage of abrasion resistance.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of glass fibre reinforced plastic insulating stepladder, comprise four support bars, supporting bar top is installed gripper shoe, every support bar is made up of the plastic layer that hollow glass steel lining and hollow glass steel lining periphery coat, the plastics stull is installed in perforate on the support bar between per two support bars, plastics stull two ends are installed in the hole.Gripper shoe is free core glass steel lining, and plastic layer is covered in the outsourcing of glass steel lining.Support bar is cylindrical.Cavity is set in the middle of the gripper shoe.The gripper shoe lower end is provided with lug, and supporting bar top inserts between two lugs, and bearing pin is with support bar and gripper shoe hinge.Sheath is installed in the support bar bottom.Offer through hole in the stull.
Advantage of the present utility model is: good insulation preformance, long service life can be used in any environment, does not need the wear condition of running check insulating ladder, the allergy to human body skin, injury such as itch do not occur, and is easy to use, is connected firmly etc.
Description of drawings
The specific embodiment
Insulating ladder of the present utility model has four support bars, and supporting bar top is installed gripper shoe 9, and a side of gripper shoe 9 is installed first support bar 2 and second support bar 8, and the opposite side of gripper shoe 9 is installed two support bars in addition.The structure of gripper shoe 9 can have two kinds: a kind of is to adopt glass-reinforced plastic material to make, and the centre is provided with cavity 14; Another kind is to cover plastic layer in the outsourcing of hollow glass steel lining.The support bar of the utility model insulating ladder is formed by hollow glass steel lining with at its periphery coating plastic layer, and plastics stull 7 is installed in perforate on the support bar between per two support bars, and plastics stull two ends are installed in the hole.When the plastic material strength of selecting for use is enough high, can in stull 7, offer through hole 15, to reduce manufacturing cost.Being connected between support bar and the gripper shoe 9 is hinge, is easy to make.The hinge arrangement of long service life is: in gripper shoe 9 lower ends lug 13 is set, lug has 4 groups, every group two, as shown in Figure 1, insert between two lugs at second support bar, 8 tops, adopt bearing pin with second support bar 8 and gripper shoe 9 hinges, other three support bars are identical with second support bar 8 with the connected mode of gripper shoe.Gripper shoe 9 described in the utility model is cylindrical bars, also can use square pole certainly, and the pref. cylindrical bar can reduce manufacturing cost and tool is easy to use.Can sheath be installed every support bar bottom for reducing wear, 1 is bearing pin among the figure, the 3rd, and hollow glass steel lining, 5 is first sheaths, 6 is second sheaths, the 4th, stull, 10 is the 3rd support bars, the 16th, lug.
Claims (7)
1, a kind of glass fibre reinforced plastic insulating stepladder, comprise four support bars, supporting bar top is installed gripper shoe (9), it is characterized in that: every support bar is made up of the plastic layer that hollow glass steel lining and hollow glass steel lining periphery coat, perforate on the support bar, the plastics stull is installed between per two support bars, and plastics stull two ends are installed in the hole.
