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...

The invention discloses a constant-force hanging bracket device. The constant-force hanging bracket device comprises a pipeline lifting lug, a supporting structure, a first fixed pulley, a second fixed pulley, a balancing weight and a connecting piece, wherein the pipeline lifting lug is arranged above a suspended pipeline and is used for providing suspension force for the suspended pipeline; a first fixing part and a second fixing part are arranged on the supporting structure; a first fixed pulley is positioned by the first fixing part; the second fixed pulley is positioned through the secondfixing part; the weight of the balancing weight is the same as the load of the suspended pipeline, and the weight of the balancing weight is less than 493N; and one end of the connecting piece is connected with the pipeline lifting lug, and the other end of the second fixed pulley sequentially penetrates through the first fixed pulley and the second fixed pulley and then is connected with the balancing weight. According to the constant-force hanging bracket device, the small-load large-displacement supporting can be realized, and therefore the problem in the prior art is overcome.
Description
technical field [0001] The invention relates to the technical field of using chemical pipeline support, in particular to a constant force hanger 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 choosing a hanger, it is difficult for designers to choose. They must consider both the span of the hanger 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...
