Abstract

The utility model discloses a foldable railing, which comprises at least one lower part upright post (1) and an upper part railing (4), wherein the lower part upright post (1) is in a double-sectional-steel structure, a vertical part of the upper part railing (4) is hinged inside the double sectional steel, a pair of reverse V-shaped chutes which are symmetrical to the axial line direction of the lower part upright post and a pair of I-shaped chutes are sequentially arranged on and under the lower part upright post (1), the length of the I-shaped chutes is greater than or equal to the length of chutes of the sealed ends of the reverse V-shaped chutes, one ends of the V-shaped chutes are in an open type, and one end of the upper part railing (4) hinged inside the double-sectional-steel structure is fixedly connected with fixed pin shafts (2) corresponding to the reverse V-shaped chutes and the I-shaped chutes. The foldable railing has a simple structure and is convenient to manufacture, the normal protection function of the railing is not influenced, the railing can be folded when being not used, and the problems of the space waste and even the problem of interference with other equipment caused by fixed railing height are solved.

Description

Foldable balustrade

Technical field

The utility model belongs to mechanical field, relates in particular to a kind of Foldable balustrade that uses on mechanical equipment.

Background technology

At present, at many machineries and other equipment,, all need to install protection railing as elevator machinery.Sometimes because the space constraints of objective environment in order to prevent the mutual interference of equipment room, must limit the height of railing.Like this, might violate relevant regulations, cause rail height to be not enough to play the effect of protection personal safety simultaneously.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the railing of existing form because the mutual interference of the equipment room that altitude hold may cause.This device can not only effectively reduce the height of railing under non-application state, and when having personnel to pass through passage must to use railing, is elevated to required safe altitude simply and easily.

The technical solution of the utility model is: a kind of Foldable balustrade is provided, comprises: at least 1 lower pole and upper rail; Described lower pole is the dimorphism steel structure, and a upper rail part is articulated in dimorphism steel structure inside; Described lower pole is provided with a pair of up and down and reverse V-shaped chute and a pair of I type chute its axis direction symmetry successively, and the length of described I type chute is more than or equal to the length of the chute of the closed end of reverse V-shaped chute; One end of described V-type chute is open; Described upper rail is articulated in dimorphism steel structure in-to-in one end and is fixedly connected with and reverse V-shaped chute and the cooresponding fixed pin shaft of I type chute.

Foldable balustrade one optimal technical scheme that provides according to the utility model is that described railing comprises: at least 2 pairs of lower pole and upper rail are provided with the bottom crosspiece between described adjacent 2 pairs of lower pole.

The beneficial effects of the utility model are simple in structure, and are easy to make, do not influence the normal defencive function of railing; Railing can fold when not using, and has overcome owing to rail height is fixed space waste that causes even the problem of interfering with other equipment.

The specific embodiment

Be described in detail specific embodiment of the utility model below in conjunction with technical scheme and accompanying drawing.

Embodiment:

As shown in Figure 3, the Foldable balustrade of present embodiment comprises two lower pole 1, produce two chutes of inverted V-shaped and I type on it, upper rail 4 is installed two cylindrical fixed pin shafts 2 in corresponding position, requires fixed pin shaft 2 and upper rail 4 to be welded to connect or guarantees that with additive method relative motion can not be arranged.Install according to illustrated in figures 1 and 2.

Like this, the first half can be rotated the junction around between two parts.At ordinary times, the first half of falling, like this, the height of railing has only about half of desired height, can save the space of platform top greatly; By platform, when needing railing protection personal safety, erect upper rail as personnel, two fixed pin shafts on the upper rail column are stuck in the chute of bottom railing, thereby reach required safe altitude.

Fell railing process as shown in Figure 4.(1) is initial condition; Upper rail is upwards mentioned, made two fixed pin shafts arrive the apical position of two chutes, shown in Fig. 4 (2); Along reverse V-shaped chute inclined upper railing slowly, shown in (3)-(7) that Fig. 4 plants.The upper rail of falling fully reaches state shown in Figure 5.

The process of desired height railing was opposite with above process when railing became personnel by passage by the state of falling.

Claims

1. a Foldable balustrade is characterized in that, described railing comprises: at least 1 lower pole (1) and upper rail (4); Described lower pole (1) is the dimorphism steel structure, and upper rail (4) vertically part is articulated in dimorphism steel inside; Described lower pole (1) is provided with a pair of up and down and reverse V-shaped chute and a pair of I type chute its axis direction symmetry successively, and the length of described I type chute is more than or equal to the length of the chute of the closed end of reverse V-shaped chute; One end of described V-type chute is open; Described upper rail (4) is articulated in dimorphism steel structure in-to-in one end and is fixedly connected with and reverse V-shaped chute and the cooresponding fixed pin shaft of I type chute (2).

2. Foldable balustrade according to claim 1 is characterized in that, described railing comprises: at least 2 pairs of lower pole (1) and upper rail (4) are provided with bottom crosspiece (3) between described adjacent 2 pairs of lower pole (1).
