Abstract
The utility model discloses a light-duty staircase step tripod, including the slice main part, a plurality of polygons well kenozooecium have been seted up at slice main part middle part, well kenozooecium perisporium edge forms the strengthening rib towards one side turn-ups. The utility model provides the high tripod bears the ability of normal pressure and side torsion, under the prerequisite of assurance tripod intensity, can alleviate the weight of tripod, has reduced manufacturing material's use to reduce consumeing of electric energy when the elevator moves, practice thrift production and running cost.
Description
Technical field
The utility model relates to a kind of light-duty ladder stair tripod.
Background technology
Ladder step tripod is one of basic building block of existing assembly type step, is made by the sheet metal backfin, and support body is roughly triangular in shape, and the middle part has the triangle hollow bulb.Stair step generally includes two spiders of vertically installing, being parallel to each other, and the spider top is connected with the pedal assembly of trampling for the passenger; The rear end is connected with the kickplate assembly of step; Front end is connected with in order to strengthen the loading strength of stair step, particularly bears the effect from the power of vertical directions such as pedal assembly, and the front cross rail that is subjected to displacement of the spider that is parallel to each other of restriction and the main wheel axle bed that is used to form loop pulling ladder road; The lower end of spider is connected with the jockey pulley of supporting step to move by the jockey pulley seat.During the step operation, two vertical installations, spiders parallel to each other must bear from the power on the vertical directions such as pedal assembly and passenger weight, also must bear the tractive force from the main wheel axle bed simultaneously.Therefore, spider is the load-bearing core component of stair step, for the loading strength that guarantees staircase when operation meets the safe operation standard and step is integrally-built stable, prevent the bending that is distorted under the effect of spider because of the tractive force of undercapacity in the vertical direction and front end, cause whole terraced road et out of order, and then bring hidden danger to passenger safety, the support body of spider must be selected more thick and heavy sheet metal for use, but adopt the stair step weight of this structure spider heavier, the productive costs height, electric energy was wasteful when the ladder road was moved, the operating cost height.
Summary of the invention
The utility model purpose provides a kind of light-duty ladder stair tripod, it has improved the ability that spider bears positive pressure and side torsion, under the prerequisite that ensures spider intensity, can alleviate the weight of spider, reduced the use of producing material, and the expending of electric energy when having reduced the elevator operation, save and produce and operating cost.
The technical solution of the utility model is: a kind of light-duty ladder stair tripod, comprise flake main body, and described flake main body middle part offers some polygon hollow bulbs, and all mural margins of described hollow bulb form reinforced rib towards a side flanging.
The technical solution of the utility model is: a kind of light-duty ladder stair tripod, comprise flake main body, and described flake main body middle part offers some polygon hollow bulbs, and all mural margins of described hollow bulb form reinforced rib towards a side flanging; Described flake main body edge reinforced rib outside a side flanging forms, described outer reinforced rib and reinforced rib homonymy are provided with; Described flake main body be provided with the main wheel axle bed on the cooresponding knock hole of locating convex block, described flake main body and main wheel axle bed be by locating convex block and cooresponding knock hole positioning combination, and connect with welding method.
The utility model advantage is:
1. the utility model is offered some hollow bulbs at spider flake main body middle part, and hollow bulb perisporium and flake main body edge be provided with respectively reinforced rib and outside reinforced rib, can prevent effectively that spider from producing the distortion bending because of the effect from pedal assembly, passenger weight and tractive force, increase of the effect of the intensity of support body with the power of the bigger vertical direction of supporting, also help to increase support body for load-bearing rigidity, improve the bending resistance folding endurance under loading condition from the main wheel tractive force.
2. the utility model satisfies under the situation of step operation bearing safety requirement in intensity, and flake main body can adopt the thin sheet material manufacturing of relative thickness, alleviates support body weight, thereby the step gross weight that realizes same specification reduces, and saves and produces and operating cost.
3. the knock hole that is provided with of the utility model spider cooperates location and riveted joint with positioning boss on the main wheel axle bed, connects with welding method again, and the assembling location is convenient, has changed the loosening defective of screw ease of connection of former mounting structure simultaneously.
Description of drawings
Fig. 1 is the perspective view of the utility model specific embodiment;
Fig. 2 is the perspective view at the another visual angle of the utility model specific embodiment;
Fig. 3 is the application state scheme drawing of the utility model specific embodiment.
Wherein: 1 flake main body; 2 hollow bulbs; 3 reinforced ribs; 4 outer reinforced ribs; 5 knock holees; 6 main wheel axle beds; 7 locating convex blocks; 8 pedal assemblies; 9 kickplate assemblies; 10 jockey pulley assemblies.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as depicted in figs. 1 and 2, a kind of light-duty ladder stair tripod, comprise flake main body 1, described flake main body 1 middle part offers a triangle hollow bulb 2 and 2, two hollow bulbs of a quadrangle hollow bulb, 2 all mural margins form reinforced rib 3 towards a side flanging.
Described flake main body 1 edge reinforced rib 4 outside a side flanging forms, described outer reinforced rib 4 and reinforced rib 3 homonymy settings.
Described flake main body 1 is provided with knock hole 5, and this knock hole 5 cooperates location and riveted joint with positioning boss 7 on the main wheel axle bed 6, connects with welding method again, and the assembling location is convenient, has changed the loosening defective of screw ease of connection of former mounting structure simultaneously.
Be illustrated in figure 3 as the structural representation of stair step, wherein the top of spider is connected and fixed pedal assembly 8, and the rear end of spider connects the kickplate assembly, and the below of spider front end is connected with main wheel axle bed 6, and the below of rear end is connected with jockey pulley assembly 10.
The utility model has improved the ability that spider bears positive pressure and side torsion, under the prerequisite that ensures spider intensity, can alleviate the weight of spider, reduced the use of producing material, and the expending of electric energy when having reduced the elevator operation, save and produce and operating cost.
