Description
Technical field
The utility model relates to a kind of suspension bracket, and the coaxial constant supporting spring hanger of particularly a kind of roller guiding type is used for the industrial pipeline or the equipment of industries such as electric power, chemical industry and need thermal walking and pipe portion and the root occasion at same vertical line be arranged at vertical direction.
Background technique
Existing coaxial constant supporting spring hanger structure is to have a top to be provided with the cover tube of hanging bearing pin, there is the cover tube end plate of band center hole the lower end of cover tube, on the cover tube end plate, be positioned at cover tube inboard and be provided with spring, the upper end of spring is provided with the pressing plate of band center hole, the upper end of pull bar protrudes upward and the termination is connected to nut from the center hole of pressing plate, stretch out downwards and lower end and extension spring frame join from the center hole that covers tube end plate the lower end of pull bar, the extension spring frame joins by revolution conduction mechanism and load bolt, and load bolt lower end is connected to the degree of tightness nut; Be connected to casing below the cover tube end plate, casing is positioned at the outside of revolution conduction mechanism.During installation, utilization is hung bearing pin this suspension bracket is hung on basic support body, hangs pipeline or relevant device by the degree of tightness nut of below.The gravity of being hung on spring, formed flexible suspension, but in the vertical direction forms a certain amount of thermal walking in running by degree of tightness nut, load bolt, force transmission mechanism, extension spring frame, pull bar and pressing plate function.The suspension bracket of this structure has following shortcoming: spring is compressed in the process, and self can reverse, and drives pull bar and the extension spring frame is also done equidirectional reversing, and at this moment, the extension spring frame can directly produce sliding friction with the side plate of casing.If run into the bigger working condition of load and displacement, it is big that spring force also becomes thereupon, and it is quite obvious that the friction of extension spring frame and casing then becomes, and has a strong impact on the suspension bracket performance, even direct stuck and can't satisfy the displacement of suspension bracket.
Summary of the invention
The purpose of this utility model provides not produce between a kind of stressed post-tensioning spring support and the casing and directly contacts and sliding friction phenomenon, the upper and lower displacement of extension spring frame are convenient freely, the coaxial constant supporting spring hanger of roller guiding type that guarantees suspension bracket proper functioning, no stuck phenomenon, overcomes the deficiencies in the prior art.
The coaxial constant supporting spring hanger of roller guiding type of the present utility model, comprise that the top is provided with the cover tube of hanging bearing pin, there is the cover tube end plate of band center hole the lower end of cover tube, on the cover tube end plate, be positioned at cover tube inboard and be provided with spring, the upper end of spring is provided with the pressing plate of band center hole, the upper end of pull bar protrudes upward and the termination is connected to nut from the center hole of pressing plate, stretch out downwards and lower end and extension spring frame join from the center hole that covers tube end plate the lower end of pull bar, the extension spring frame joins by revolution conduction mechanism and load bolt, and load bolt lower end is connected to the degree of tightness nut; Be connected to casing below the cover tube end plate, casing is positioned at the outside of revolution conduction mechanism; The side of described extension spring frame is symmetrically arranged with roller about the center, is symmetrically arranged with the stiffening plate of vertical direction about the center in the inboard of casing, and roller and stiffening plate match.
The coaxial constant supporting spring hanger of roller guiding type of the present utility model, because the roller that has the stiffening plate with the setting of box inside vertical direction to match at the side of extension spring frame, when the extension spring frame moves up and down, as twist, roller can match with stiffening plate and roll on stiffening plate, has played good leading role, overcome the phenomenon of extension spring frame and box inside surface friction, make the extension spring frame convenient freely up and down, no stuck phenomenon takes place, and has guaranteed the proper functioning of suspension bracket.
