Abstract
The utility model relates to a stair subsidence protective device which is used for subsidence protection of stairs or footboards of an escalator and a moving sidewalk and belongs to protective devices for escalators. The stair subsidence protective device comprises a hexagonal steel fixing rod, U-shaped plates, a nylon fixing sleeve, a leaf spring and a plurality of screws. The U-shaped plates are installed at the two ends of the hexagonal steel fixing rod. The U-shaped plates and the hexagonal steel fixing rod are installed on a stair guide rail through bolts. The nylon fixing sleeve and the leaf spring are installed on the inner sides of the U-shape plates at the two ends of the hexagonal steel fixing rod respectively. The screws are installed on the portion, between the nylon fixing sleeve and the leaf spring, of the hexagonal steel fixing rod. The stair subsidence protective device is applied to the escalators or moving sidewalks and has the advantages of being high in strength, light in material, good in tenacity, convenient to assemble and the like.
Description
Technical field
The utility model relates to a kind of safety guard while sinking for escalator and step of moving pavement or pedal, specifically relates to a kind of stairs sinking protection device for sinking device under step or pedal.
Background technology
In escalator or moving sidewalk use procedure, because staircase structure is complicated, part position exists gap to cause foreign matter to be absorbed in or mechanical breakdown causes the problems such as stair step misplaces, sink, and has a strong impact on safety.When step or pedal sink, a safe fixed cover can be set conventionally, conventional sagging fixed cover generally adopts round steel to make, the fixed cover of round steel material exists feed consumption many, volume weight, processing difficulties, the problems such as dismounting is loaded down with trivial details, simultaneously, because staircase is used for outdoor, the situations such as getting rusty very easily appears in round steel fixed cover, this affects its outward appearance on the one hand, also shortened its service life on the other hand, what is more important, the fixed cover getting rusty can rupture at any time, and this fracture is negative, in most cases be difficult for realizing, thereby safety factor is lower, fracture hidden danger is failed and constantly, damage to the pedestrian who takes elevator.
Utility model content
For overcome the safety factor existing in prior art low, the defect loaded down with trivial details, service life is short is installed, the utility model provides that a kind of intensity is high, material light, good toughness, staircase safety guard easy to assembly.
For achieving the above object, the technical scheme that the utility model is taked is as follows:
A kind of step sinking protection device; comprise hexagonal steel fixed link, U-shaped plate, nylon fixed cover, sheet spring and some screw rods; described U-shaped plate is installed on the two ends of hexagonal steel fixed link; U-shaped plate and hexagonal steel fixed link are installed on step roller track by bolt; nylon fixed cover and sheet spring are installed on respectively the U-shaped plate inner side at hexagonal steel fixed link two ends, and screw rod is installed on the hexagonal steel fixed link between nylon fixed cover and sheet spring.
For realizing better result of use, further arranging of technique scheme is as follows:
Described U-shaped plate opening is relative, and nylon fixed cover and sheet spring are installed on respectively in the opening of U-shaped plate.
Described screw rod is installed on hexagonal steel fixed link with the Central Symmetry of hexagonal steel fixed link, and the spacing of adjacent screw rod is identical.
Described U-shaped plate and nylon fixed cover are fixed on hexagonal steel fixed link by elastic cylindrical pin respectively.
The stairs sinking protection device that adopts technique scheme, its principle of work and beneficial effect are as follows:
In the utility model, fixed cover adopts nylon material, guarantee its powerful in, the quality of having given full play to nylon material is light, the advantage of good toughness, environmental protection, simultaneously, process also easy, importantly: in the utility model, fixed cover, U-shaped plate, screw rod all can be distinguished moulding, have shortened the process-cycle, have improved work efficiency, then by bolt, pin etc., realize and installing, both be conducive to dismounting and installed, and can improve again the degree of utilization of each parts, corresponding cost also can be reduced; And for the metals such as round steel, there is not the problem such as rotten of getting rusty in nylon material, avoided maintenance, potential safety hazard, and outward appearance is better, can meet user demand, can keep graceful outward appearance again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1-nylon fixed cover, 2-hexagonal steel fixed link, the U-shaped plate of 31-first, the 32, second U-shaped plate, 4-screw rod, 5-sheet spring, 61-elastic cylindrical pin one, 62-elastic cylindrical pin two, 7-step roller track, 81-bolt one; 82-screw rod two.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of novel step sinking protection device of the present embodiment; in conjunction with Fig. 1; comprise nylon fixed cover 1, hexagonal steel fixed link 2, U-shaped plate, some screw rods 4 and sheet spring 5; the U-shaped plate 32 of the first U-shaped plate 31, second is installed on respectively the two ends of hexagonal steel fixed link 2; the first U-shaped plate 32 of U-shaped plate 31, second and hexagonal steel fixed link 2 are installed on step roller track 7 by bolt 8; nylon fixed cover 1 and sheet spring 5 are installed on respectively U-shaped plate 3 inner sides at hexagonal steel fixed link 2 two ends, and screw rod 4 is installed on the hexagonal steel fixed link 1 between nylon fixed cover 1 and sheet spring 5.
Wherein, in the present embodiment, in installation process, first each screw rod 4 is equidistantly sleeved on hexagonal steel fixed link 2, after nylon fixed cover 1 and the first U-shaped plate 31 are sleeved on one end of hexagonal steel fixed link 2, and the first U-shaped plate 31 use bolts 1 are fixed on to the below of step roller track 7, with elastic cylindrical pin 1, nylon fixed cover 1 is fixed on hexagonal steel fixed link 2; Again sheet spring 5 upper ends and the second U-shaped plate 32 are sleeved on hexagonal steel fixed link 2, the second U-shaped plate 32 use bolts 2 82 are fixed on step roller track 7 belows, sheet spring 5 lower ends are fixed on after the second U-shaped plate 32, by elastic cylindrical pin 2 62, the second U-shaped plate 32 is fixing with hexagonal steel fixed link 2, whole sinking protection device installs; When not needing practicality or parts wherein to have the defects such as damage, then elastic cylindrical pin, disassembling bolts can be taken off to corresponding U-shaped plate, sheet spring 5, screw rod 4 or nylon fixed cover 1, only remove the parts that cannot normally work.
Adopt the utility model sinking protection device, fixed cover adopts nylon material to form nylon fixed cover 1, guarantee its powerful in, the quality of having given full play to nylon material is light, the advantage of good toughness, environmental protection, simultaneously, process also easy, importantly: in the utility model, fixed cover, U-shaped plate, screw rod 4 all can be distinguished moulding, have shortened the process-cycle, have improved work efficiency, then by bolt, pin etc., realize and installing, both be conducive to dismounting and installed, and can improve again the degree of utilization of each parts, corresponding cost also can be reduced; And for the metals such as round steel, there is not the problem such as rotten of getting rusty in nylon material, avoided maintenance, potential safety hazard, and outward appearance is better, can meet user demand, can keep graceful outward appearance again.
