Description

Изобретение относится к элементам крепления, подвергаемым нестационарным температурным воздействиям и может быть использовано, в частности для подвешивания стояков к барабану котла.The invention relates to fasteners subjected to non-stationary temperature effects and can be used, in particular, for hanging risers to the boiler drum.

Наиболее близким к предлагаемому является узел соединения стояка с барабаном, охваченным полухомутом, выполненным из звеньев, шарнирно соединенных между собою Г13 ·Closest to the proposed is the connection node of the riser with the drum covered by a half-clamp made of links articulated between themselves G13 ·

Недостаток известной конструкции низкая надежность, обусловленная перемещением подвески и скольжением звеньев полухомута по барабану при нестационарном температурном режиме.A disadvantage of the known design is low reliability due to the movement of the suspension and the sliding links of the coupling half on the drum under non-stationary temperature conditions.

Цель изобретения - повышение надежности . зпThe purpose of the invention is to increase reliability. sn

Поставленная цель достигается тем, что корпус барабана снабжен упорами, шарнирно соединенными со звеньями полухомута, крайние из которых также шарнирно соединены со стояком, причем ближайшие к горизонтальной оси барабана упоры расположены со смещением от последней в сторону стояка.This goal is achieved by the fact that the drum body is equipped with stops pivotally connected to the links of the coupling half, the last of which are also pivotally connected to the riser, the stops closest to the horizontal axis of the drum being offset from the latter towards the riser.

На фиг.1 изображено соединение стояка с барабаном, общий вид; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows the connection of the riser to the drum, a General view; figure 2 is a section aa in figure 1.

Устройство.содержит барабан 1, охваченный полухомутом, образованным шарнирно соединенными между собою звеньями 2 и 3. Крайние звенья полухомута соединены шарнирно, через серь ги 4 со стояком 5, который отводами 6 подключен по рабочей среде к барабану 1.The device comprises a drum 1, covered by a half-clamp formed by links 2 and 3 pivotally interconnected. The extreme half-clamp links are pivotally connected through the earrings 4 to the riser 5, which is connected to the drum 1 via working medium by taps 6.

Корпус барабана 1 снабжен упорами 7, шарнирно соединенными со звеньями полухомута, причем ближайшие к горизонтальной оси барабана упоры расположены со смещением от этой оси в сторону стояка 5.The housing of the drum 1 is equipped with stops 7, pivotally connected to the links of the coupling half, and the stops closest to the horizontal axis of the drum are offset from this axis towards the riser 5.

В процессе работы котла температурные удлинения корпуса 1 и звеньев 2 и 3 полухомута различны. Разность температурных удлинений компенсируется перемещением звеньев полухомута вокруг упоров 7.During the operation of the boiler, the temperature elongations of the housing 1 and the links 2 and 3 of the coupling half are different. The difference in temperature elongations is compensated by the movement of the half-clamp links around the stops 7.

Наличие на поверхности барабана упоров, шарнирно .соединенных со звеньями полухомута, позволяет повысить надежность работы предлагаемого узла.The presence on the surface of the drum stops, pivotally connected to the links of the coupling, improves the reliability of the proposed site.

Claims

The invention relates to fasteners subjected to non-stationary temperature effects and can be used, in particular, for suspending the drains from the boiler drum. Closest to the present invention is a node connecting the drain with a drum covered by a semi-hose made of links hinged between one another. A disadvantage of the known construction is low reliability due to movement of the suspension and sliding of the semi-hose links along the non-stationary temperature mode. The goal is achieved by the fact that the drum casing is provided with stops hingedly connected to the heatsink links, the outermost of which are also hingedly connected to the stand, with the stops closest to the horizontal axis of the drum located offset from the last to the stand. Figure 1 shows the connection of a stand with a drum, a general view; figure 2 - section aa in figure 1. The device contains a drum 1, covered by a half-hose, formed by arnirno connected between themselves links 2 and 3. The extreme links of the half-hose are pivotally connected, through earrings 4 to the stand 5, which branches 6 are connected to the drum 1 by means of the working medium. 7, which are pivotally connected with the half-hub links, with the stops closest to the horizontal axis of the drum being offset from this axis toward the stand 5. During the boiler operation, the temperature lengthening of the housing 1 and the links 2 and 3 of the half-hitch are different. The difference in temperature lengthening is compensated by moving the half-hub links around the stops 7. The presence of the stops on the drum surface, which are hingedly connected to the half-hub links, makes it possible to increase the reliability of the proposed unit. Claim 1. Blend assembly with drum covered by semi-hose, ball
