Description

Technical Field

[0001] The utility model relates to the technical field of spring hangers, in particular to a sleeve spring type variable spring hanger. Background Art

[0002] ‌The variable spring hanger is a hanger that allows the pipe to move vertically within a limited range. It is equipped with a spring and is suitable for pipes with vertical displacement. After searching, the existing technology (Announcement No.: CN202120705709.7) is a variable spring hanger with damping. The article records that "when encountering a moment of gravity hanging, the damping spring inside the damping sleeve is pulled by the hanger buckle, causing it to also produce a relatively large elastic deformation. This elastic deformation will share part of the tension on the tension spring, so that the tension spring is buffered to a certain extent, and when the second metal support plate drops to a When the spring is pulled to a certain degree, its outer wall will contact the inductive switch, activating the inductive switch and moving the metal pin, so that the metal pin is inserted into the inner wall of the damping sleeve and just fits into the clamping hole at its upper end, thereby stopping the deformation of the damping spring and reducing the risk of damage to the damping spring. The whole process makes the hanger itself have a certain buffering effect and will not be damaged by instantaneous pulling force, thereby improving the safety of the device. However, in the prior art, the insertion of the pin in the spring hanger is controlled by the inductive switch. When the damping spring deformation descending speed is inconsistent with the insertion speed, it is difficult for the pin to be accurately locked to prevent the damping spring from deforming.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Reference Figures 1 to 4 As shown, the utility model provides a sleeve spring type variable spring hanger, comprising: a variable spring hanger housing 1 and a load column 2, wherein the load column 2 is provided inside the variable spring hanger housing 1.

[0020] A cylindrical coil spring 3 is distributed around the inside of the variable spring hanger housing 1. The cylindrical coil spring is located on the lower surface of the load column 2. The lower end of the load column 2 is connected to a limiting pressure plate 31. The lower end of the limiting pressure plate 31 is fixed with a compression spring tube 4. The inside of the compression spring tube 4 is connected to a fixing block 43 through a chromium-molybdenum alloy steel spring 42. A compression support 41 is welded to the upper end of the fixing block 43. The compression support 41 passes through the inner end of the cylindrical coil spring 3.

[0021] First, the sleeve spring type variable spring hanger is connected to the pipeline or equipment through the lifting assembly, and the compression support 41 pushed by the chromium-molybdenum alloy steel spring 42 in the compression spring tube 4 supports the downward load column 2, and cooperates with the cylindrical coil spring 3 to bear the load force of the load column 2, so as to prevent the cylindrical coil spring in the variable spring hanger from excessive deformation and failure or breakage, enhance the load of the sleeve spring type variable spring hanger, facilitate the sleeve spring type variable spring hanger to more stably support the suspended equipment, and improve the durability of the sleeve spring type variable spring hanger.

[0022] In this embodiment, a mounting base 11 is welded to the lower end of the variable spring hanger housing 1. Mounting holes are defined in the mounting base 11. A top cover 12 is screwed to the upper end of the variable spring hanger housing 1. The lower end of the load column 2 is secured to the variable spring hanger housing 1 via a locating pin. The upper end of the load column 2 extends through the upper end of the top cover 12.

[0023] As a preferred embodiment, the damping ring block 5 facilitates positioning of the load column 2, facilitating stable support via the cylindrical coil spring 3 after assembly of the load column 2 with the hoisting rod. The variable spring hanger housing 1 passes through the center sleeve 13 via the hoisting rod and is screwed to the upper surface of the load column 2. The weight of the pipe or equipment suspended at the lower end of the hoisting rod causes the load column 2 to move downward, allowing the cylindrical coil spring 3 and compression spring tube 4 to cushion the downward pressure on the load column 2, thereby stably supporting the suspended pipe or equipment.

[0024] In this embodiment, a central sleeve 13 is welded to the center of the inner side of the variable spring hanger housing 1. The cylindrical coil spring 3 and the compression spring tube 4 are located at the outer end of the central sleeve 13. Four sets of through-grooves 32 are formed on the surface of the limiting pressure plate 31. Compression-resistant struts 41 extend through these grooves. The outer sides of the compression struts 41 are tightly attached to the inner wall of the variable spring hanger housing 1 and the outer surface of the central sleeve 13 via the damping ring block 5.

[0025] As a preferred embodiment, the cylindrical coil spring 3 and the compression spring barrel 4 serve as the primary and secondary support structures for the downward-pressing load column 2, effectively buffering the deformation of the cylindrical coil spring 3 under compression. Furthermore, the chromium-molybdenum alloy steel spring 42 within the compression spring barrel 4 exhibits excellent, long-lasting elasticity and resists plastic deformation during use, thereby extending the service life of the sleeve-spring variable spring hanger. The damping ring block 5 acts as a vibration damper and reduces impact.

[0026] In this embodiment, the cylindrical coil spring 3 , the limiting pressure plate 31 , the compression spring tube 4 , the compression support 41 and the chromium-molybdenum alloy steel spring 42 constitute a dual elastic support structure of the variable spring hanger housing 1 .

[0027] As a preferred embodiment, the dual elastic support structure of the variable spring hanger housing 1 facilitates the coordinated bearing of the load force exerted on the load column 2, prevents the cylindrical coil spring inside the variable spring hanger from excessive deformation and failure or breakage, and enhances the load of the sleeve spring type variable spring hanger.

[0028] The sleeve spring type variable spring hanger of the utility model can effectively solve the problem in the prior art that the pin is difficult to accurately engage to prevent the damping spring from deforming when the damping spring deformation descending speed is inconsistent with the plug-in speed, and is convenient for preventing the cylindrical coil spring in the variable spring hanger from excessive deformation and failure or breakage, thereby enhancing the load of the sleeve spring type variable spring hanger, facilitating the sleeve spring type variable spring hanger to more stably support the suspended equipment, and improving the durability of the sleeve spring type variable spring hanger, and is suitable for the sleeve spring type variable spring hanger.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
