Abstract

The utility model relates to a stair of a railway wagon ladder. The stair is characterized by comprising a stair body, wherein a plurality of symmetric grooves extending in the length direction of the stair body are formed in the upper end surface of the stair; the middle upper part of each of the two side walls of the stair body is a plane; the two sides of the middle lower part of each of the two side walls of the stair body adopt inwards recessed circular pocket-type structures; the lower end surface of the stair is an arc surface. As the plurality of symmetric grooves extending in the length direction of the stair are formed in the upper end surface of the stair, rubber at the sole is easy to embed into the stair when feet of operators tread on the upper end surface of the stair, the possible sliding in treading is effectively prevented, the potential safety hazard is reduced, and the essential safety of a wagon is improved. The two sides of the middle lower part of each of the two side walls of the stair adopt the inwards recessed circular pocket-type structures, so that the fact that fingers can hold tightly without sliding when the operators hold the ladder by hands is ensured, and the effect is more remarkable particularly when the operators wear relatively thick gloves in winter. Therefore, the stair can be widely applied to railway wagon ladder.

Description

A kind of step of rail wagon ladder
Technical field
The utility model relates to a kind of step, particularly about a kind of step of rail wagon ladder.
Background technology
On the side wall of railway freight-car, headwall, be provided with for lorry handling goods or in the time shunting for the upper and lower staircase of operating personnel, owing to being subject to the restriction of lorry width, the thickness of staircase can not arrange larger, and the step of staircase generally by the round steel of 16mm~20mm is made.Lorry is when sleety weather carries out operation out of doors, and operating personnel gets on or off the bus needs the step with hand grip, foot-operated staircase, and easily causes landing because step exists water, ice, snow, causes operating personnel to be prone to unexpected security incident.At present, because the cost reason of the restriction in the space of lorry own and step, the step structure of lorry staircase changes not yet, therefore still has potential safety hazard.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of step that conveniently grasps and prevent the rail wagon ladder of landing.
For achieving the above object, the utility model is taked following technical scheme: a kind of step of rail wagon ladder, is characterized in that: it comprises a step body, and the upper surface of described step has upwardly extending some symmetrical grooves along described step body length side; The middle and upper part of described step body two side is a plane, and both sides, middle and lower part all adopt the circular nested structure of indent; The lower surface of described step is an arc surface.
Each corner of described step all arranges arc chord angle transition.
The material of described step is straight carbon steel, weather-proof steel or stainless steel.
On the upper surface of described step, be two grooves, and groove is inverted trapezoidal groove, depth of groove is 0.6mm~1mm.
The length and width degree of cross section of described step is 20mm~26mm, and degree of growing tall is 20mm~22mm most.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is owing to having in the upper surface of step along some symmetrical grooves of extending on step length direction, therefore operating personnel rides in the time of the upper surface of step, the rubber of sole easily embeds, effectively prevent the landing that may occur while riding, reduce potential safety hazard, to improve the safety of lorry.The utility model also all adopts the circular nested structure of indent in the both sides, middle and lower part of step two side, to ensure that operating personnel is when the hand grip, finger grips is not slided, and when operating personnel is with compared with muffler especially in the winter time, effect is more obvious.2, each corner of the utility model step all arranges arc chord angle transition, is a smooth continuous curve surface that there is no sharp corners to form the external surface of step, in the time that operating personnel uses hand grip, can firmly hold with a firm grip, can not cause the injury to operating personnel.The special cross-section of the similar T shape structure that 3, the utility model adopts, the length and width degree of its cross section is 20mm~26mm, degree of growing tall is 20mm~22mm most, in exterior surface area of the present utility model and existing step, adopts 20mm round steel exterior surface area is suitable, but adopt vertical, the horizontal bending resistant section coefficient of the utility model step larger, and it is existing while utilizing the lorry staircase step that round steel makes to adopt the utility model to substitute, neither need other part to change, do not increase again the weight of extra step.4, the utility model adopts the material of low cost of manufacture, as the steel such as steel, weathering steel, stainless steel for ordinary construction use hot rolling process to be rolled into strip by rolling mill, sawing length while only needing blanking, neither need it to carry out machining, therefore can reduce manufacturing cost, additionally not increase again the cost of manufacture of step.In view of above advantage, the utility model can be widely used in rail wagon ladder.

Detailed description of the invention
Be described in detail of the present utility model below in conjunction with drawings and Examples.
As shown in FIG. 1 to 3, the utility model comprises a step body 1, and the upper surface 11 of step body 1 has some symmetrical grooves 12 of extending along on step 1 length direction, so that operating personnel rides in the time of the upper surface 11 of step 1, the rubber of sole easily embeds, and prevents landing.The middle and upper part of the two side 13 of step 1 is a plane, and both sides, middle and lower part all adopt the circular nested structure of indent, to ensure that operating personnel is in the time of hand grip, finger grips is not slided.The lower surface 14 of step 1 is an arc surface, makes the cross section of step 1 be approximate T shape.
In above-described embodiment, each corner of step 1 all arranges arc chord angle transition, is a smooth continuous curve surface that there is no sharp corners to form the external surface of step 1, in the time that operating personnel uses hand grip, can firmly hold with a firm grip, can not cause the injury to operating personnel.Step 1 utilizes the material of low cost of manufacture, as straight carbon steel, weathering steel, stainless steel etc. use hot rolling process to be rolled into strip by rolling mill, and need to intercept suitable length according to the staircase width that will install.
In above-described embodiment, be preferably two grooves 12 on upper surface 11, and groove 12 is inverted trapezoidal groove, depth of groove is 0.6mm~1mm.
In above-described embodiment, as shown in Figure 1, the length and width degree of the cross section of step 1 is 20mm~26mm, and degree of growing tall is 20mm~22mm most, in the cross sectional area of the step 1 of equal length and existing step, adopts the cross sectional area of 20mm round steel is suitable, and step 1 vertically and laterally has larger bending resistant section coefficient.
