Problems solved by technology

Because the minimum load value given in the standard is 493N, if it is lower than 493N, the model cannot be selected in the standard, which has caused great design difficulties for designers.
That is, if it is necessary to realize large-displacement support under a small load scenario of less than 493N, there is no effective way to realize it

Embodiment Construction

[0036] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, those skilled in the art Modifications to various equivalent forms of the present invention fall within the scope defined by the appended claims of the present application.

[0037] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar exp...

Abstract

The invention discloses a constant force bracket device. The device comprises a pipeline lifting lug, a supporting structure, a first fixed pulley, a second fixed pulley, a counterweight block and a connecting piece, wherein the pipeline lifting lug is arranged below a supported pipeline and used for providing supporting force for the supported pipeline; a first fixing part and a second fixing part are arranged on the supporting structure; the first fixed pulley is positioned by the first fixing part, and the second fixed pulley is positioned through the second fixing part; the weight of the counterweight block is the same as the load of the supported pipeline, and the weight of the counterweight block is less than 493 N; and one end of the connecting piece is connected with the pipeline lifting lug, and the other end of the connecting piece sequentially penetrates through the first fixed pulley and the second fixed pulley and then is connected with the counterweight block. According to the constant force bracket device, the small-load large-displacement support can be realized, so that the problem in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of using chemical pipeline support, in particular to a constant force support device applied in the scene of small load and large displacement. Background technique [0002] In a large number of petrochemical installations currently in operation in China, the actual situation that small diameters are often connected to high-temperature equipment is often encountered. When designers choose supports, it is difficult to choose. They must consider both the span of the support and the vertical displacement. [0003] For example, the gasifier in a coal chemical plant has a furnace body length of 60m and a design temperature of the outer wall of the furnace at 260°C. Furnace body equipment has thermal expansion at relatively high temperature, and the fixing frame moves up or down with the displacement of the furnace body equipment. The support of the furnace body is in the middle and upper part of the furnace bod...
