Abstract
The utility model relates to a novel pultrusion fiber reinforced plastic ladder which comprises pultrusion glass fiber reinforced plastic side plates and pultrusion glass fiber reinforced plastic footsteps, wherein connecting rods are arranged inside the pultrusion glass fiber reinforced plastic footsteps, and the pultrusion glass fiber reinforced plastic side plates are fixedly connected with the pultrusion glass fiber reinforced plastic footsteps through the connecting rods. The novel pultrusion fiber reinforced plastic ladder has the advantages of simple structure, high safety factor and long service life.
Description
Technical field
The utility model relates to a kind of ladder, is specifically related to a kind of glass fiber reinforced plastic ladder.
Background technology
In the production operation of common mine, pass in and out up and down mine for ease of the operator, generally need installing in the pit shaft between stepladder, by the ladder mine of coming in and going out.All make of common iron between general stepladder at present, be welded by steel such as steel plate, shaped steel, round steel.Because high humidity under the mine, and contain rotten candle property material, therefore, the solar of being made by steel very easily get rusty rotten candle, the particularly place of being welded to connect easily the generation corrosion come off, there is potential safety hazard, to this, will change member every several years and carry out preservative treatment, the protection difficulty is large, construction quality is difficult to guarantee that maintenance cost is high.Adopting in addition metal edge frame is skeleton outsourcing glass fibre reinforced plastic structure, making is to pass through hand pasting forming, outside the surface of steel, cover glass fiber reinforced plastic, because mine shaft equipment kind and specifications and models are changeable, during making, the mould that needs is more, particularly the designing requirement of each mine pit shaft differs, these moulds are finished and substantially just can not have used afterwards, have greatly wasted resource, have also increased cost of manufacture and cost of production simultaneously.The members such as the fence that hand paste technique is made, landing slab, ladder use a period of time in Minepit environment after, rust water phenomenon can appear, be that moisture can penetrate into component inside by the pore of glass fiber reinforced plastic surface, the steel of etching glass steel inside, the bearing capacity of member is reduced, reduce safety factor.
It is more loaded down with trivial details that hand is stuck with paste technique making glass fiber reinforced plastic member in addition, and quality is unstable, can bring certain potential safety hazard, and there is not re-usable shortcoming in the shaft equipment of making by hand paste technique simultaneously, has greatly wasted resource.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, safety factor height, the novel pultrusion type glass fiber reinforced plastic ladder of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of novel pultrusion type glass fiber reinforced plastic ladder described in the utility model, it comprises pultrusion type fiberglass side board and pultrusion type glass fiber reinforced plastic pedal, be provided with connecting rod in described pultrusion type glass fiber reinforced plastic pedal inside, described pultrusion type fiberglass side board is fixedly connected with by connecting rod with pultrusion type glass fiber reinforced plastic pedal.
Described connecting rod comprises pultrusion type glass fiber reinforced plastic solid core bar and is enclosed within the sleeve pipe of pultrusion type glass fiber reinforced plastic solid core bar outside.
Be provided with two connecting rods in described pultrusion type glass fiber reinforced plastic pedal inside.
The described connecting rod that draws connects by nut screwing clamping.
Described pultrusion type fiberglass side board is the rectangle side plate.
Described connecting rod is cylindrical connecting rod.
The utility model adopts pultrude process: the Non-twisting glass fibre rove on the creel is carried out resin with other continuous reinforcing materials, polyester surface felt etc. soak, then pass through to keep the moulding form of certain cross sectional shape, and make its continuous depanning after the moulding of mould internal heating curing become pultrusion product; Its main raw material(s) adds fire retardant, antistatic additive with the inferior pultrusion 191C of nation resin, the non-twist glass fiber of alkali and glass mat during its reinforcing material adopts.The curing compound of pultrusion resin heat cure is dibenzoyl peroxide BPO and peroxidized t-butyl perbenzoate (TBPB).
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model is simple in structure, safety factor is high, long service life.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pultrusion type fiberglass side board described in the utility model and connecting rod.
Wherein:
1, pultrusion type fiberglass side board; 2, pultrusion type glass fiber reinforced plastic pedal; 3, connecting rod; 4, squeeze type glass fiber reinforced plastic solid core bar; 5, sleeve pipe
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As depicted in figs. 1 and 2, a kind of novel pultrusion type glass fiber reinforced plastic ladder described in the utility model, it comprises pultrusion type fiberglass side board 1 and pultrusion type glass fiber reinforced plastic pedal 2, be provided with connecting rod 3 in described pultrusion type glass fiber reinforced plastic pedal 2 inside, described pultrusion type fiberglass side board 1 is fixedly connected with by connecting rod 3 with pultrusion type glass fiber reinforced plastic pedal 2; Described connecting rod 3 comprises pultrusion type glass fiber reinforced plastic solid core bar 4 and is enclosed within the sleeve pipe 5 of pultrusion type glass fiber reinforced plastic solid core bar 4 outsides; Be provided with two connecting rods 3 in described pultrusion type glass fiber reinforced plastic pedal 2 inside; Described connecting rod 3 connects by nut screwing clamping; Described pultrusion type fiberglass side board 1 is the rectangle side plate; Described connecting rod 3 is cylindrical connecting rod.The utility model is simple in structure, and safety factor is high, long service life.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
