Description

TECHNICAL FIELD

[0001] The utility model relates to a handrail mounting structure for rail vehicle and belongs to the field of railway vehicle. BACKGROUND

[0002] With the rapid development of social economy, people's life rhythm gradually speeds up, and convenient and fast rail vehicles become one of the preferred traffic tools for people's daily travel. Especially for part of the office workers, taking the subway has become an indispensable traffic tool for going to work and coming back home, and with the increase of the number of passengers, a large number of handrails need to be arranged on the vehicle for passengers to hold.

[0003] With the increase of the number of handrails, the mounting of the handrails becomes one of the difficulties of the vehicle. If the handrails are connected between the top plate, the strength of the top plate is affected. If the handrails are directly connected between the vehicle body, the handrails need to pass through the roof, although the strength problem of the top plate can be solved, but since the handrails are the last process for the installation of the roof area, the handrails may interfere with the top plate due to the accumulation of tolerances, and the mounting seat of the handrails needs to be adjusted twice, which affects the work efficiency. SUMMARY

[0004] The utility model mainly aims at providing a handrail structure which is beautiful, high in strength and convenient to install, solves the problem of difficult installation with the increase of the number of handrails, and can improve the work efficiency.

[0005] The utility model is realized by the following technical schemes:

[0006] A handrail mounting structure for rail vehicle, comprising a mounting seat 1, a center column assembly 2 and a top plate 3, the center column assembly 2 comprises a top seat 2-1, a variable-diameter handrail rod 2-2, a buckle cover 2-3, a center column rod 2-4 and a flange plate 2-5 from top to bottom, the upper end of the mounting seat 1 is connected with the vehicle body through bolts, the lower end is connected with the top seat 2-1 of the center column assembly 2, the small-diameter end of the variable-diameter handrail rod 2-2 is matched with the top plate 3, the top plate 3 is split at the center of the center column, and meanwhile, the buckle cover 2-3 is buckled on the matching part of the variable-diameter handrail rod 2-2 and the top plate 3 from below the top plate 3.

[0007] The mounting seat 1 is a truss type structure.

[0008] The utility model has the following beneficial effects:

[0009] (1) high strength: the center column assembly is directly connected with the vehicle body, and the overall strength of the handrail is improved;

[0010] (2) high work efficiency: the structure of the split top plate and the variable-diameter handrail increases the gap between the handrail and the top plate, greatly improves the installation process, avoids the secondary adjustment problem caused by the accumulation of tolerances, and improves the work efficiency of the operator;

[0011] (3) beautiful: in the handrail approaches the top plate place, set up the buckle cover that modeling is beautiful, shield the gap between the top plate and the handrail, avoid because the gap is more, produce the problem of disorderly, improve the beautiful nature. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is the mounting seat axis measurement schematic view:

[0013] Figure 2 It is the middle column composition axis measurement schematic view;

[0014] Figure 3 It is the installation drawing. DETAILED DESCRIPTION

[0015] The utility model handrail structure mainly includes mounting seat 1, middle column composition 2, top plate 3, and middle column composition mainly includes top seat 2-1, variable diameter handrail rod 2-2, buckle cover 2-3, middle column rod 2-4 and flange plate 2-5.

[0016] The structure is characterized in that: before installing the roof, first install the mounting seat 1 of truss type structure, and the mounting seat 1 is directly connected with the vehicle body through bolt, can improve the strength of handrail, and the mounting seat of truss type structure is high in strength itself; then, install the middle column composition 2, and the middle column composition 2 is connected with the mounting seat 1 through bolt, since the top plate 3 is divided at the middle column center, can facilitate the installation of top plate 3, and the area of top plate 3 is passed through setting variable diameter handrail rod 2-2 of smaller diameter, increases the gap between variable diameter handrail rod 2-2 and top plate 3, avoids the interference of top plate 3 and variable diameter handrail rod 2-2, prevents secondary adjustment handrail mounting seat 1, improves the work efficiency of operator; in the middle column rod 2-4 and top plate 3 gap smaller at variable diameter handrail rod 2-2 approaches top plate 3, can set up the buckle cover 2-3 of smaller volume, shield the gap between top plate 3 and handrail, improve the beautiful nature; the lower part of middle column rod 2-4 is provided with flange plate 2-5, this is mature structure, and will not be repeated here.
