Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

Hereinafter, an embodiment of the present utility model will be described in accordance with its entire structure.

The utility model provides a spring gallows convenient to adjust spring interval, as shown in fig. 1-5, including shell 1, the top sliding connection of shell 1 has bracing piece 2, the inside one end butt of being located shell 1 of bracing piece 2 has supporting spring 3, the both ends of supporting spring 3 are a set of extrusion head 4 of fixedly connected with respectively, the one end of the lateral wall fixedly connected with pull rod 5 of extrusion head 4, the other end fixedly connected with sliding frame 6 of pull rod 5, the lateral wall rotation of shell 1 has pivot 9, the one end fixedly connected with carousel 7 that the pivot 9 is located shell 1, the lateral wall fixedly connected with of carousel 7 two sets of catch bars 8, the inner wall at a set of sliding frame 6 of two sets of catch bars 8 respectively sliding connection, make carousel 7 rotate and drive two sets of extrusion heads 4 to draw close in the middle, thereby compress supporting spring 3, make you can relax more convenient when opening spring gallows, and operating personnel are difficult for being broken by the upper cover that flies by the bullet.

On the basis of the above structure, in this embodiment, the inner wall of the turntable 7 is fixedly connected with one end of the rotating shaft 9, the rotating shaft 9 drives the turntable 7 to rotate, the turntable 7 pushes the two groups of sliding frames 6 to slide on the inner wall of the housing 1 through the two groups of pushing rods 8, so that the two groups of sliding frames 6 are close to each other, and the two groups of sliding frames 6 drive the two groups of extrusion heads 4 to approach each other through the pull rod 5, so that the supporting spring 3 is compressed, and the housing 1 cannot be subjected to the elasticity of the supporting spring 3 when the housing 1 is disassembled for maintenance.

Wherein in order to drive the rotating shaft 9 to rotate, a pressing handle is fixedly connected to one end of the rotating shaft 9 positioned outside the shell 1, and the pressing handle is pressed downwards, so that the rotating disc 7 can be driven to rotate conveniently through the lever principle.

On the basis of the above structure, in this embodiment, after compressing the supporting spring 3, the threaded rod 10 is rotated, the threaded rod 10 pushes the sliding tooth 11 to interact with the outside of the turntable 7, so that the rotating tooth is meshed with the fixed tooth 12, the rotating shaft 9 cannot rotate at this time, so that the turntable 7 cannot rotate, then the pressing handle can be loosened to disassemble the casing 1, after maintenance is completed, the pressing handle is pressed by hand, then the threaded rod 10 is reversely rotated, so that the sliding tooth 11 is reset, at this time, the rotating shaft 9 can normally rotate, and then the pressing handle is slowly lifted, so that the spring support hanger can be continuously and normally used.

On the basis of the above structure, in this embodiment, when the pipe is fixed to the spring hanger, by placing the pipe inside the bracket 13, two ends of the bracket 13 are respectively connected with a set of rotating plates 14 in a rotating manner, during the process of placing the pipe, the pipe contacts with two sets of rotating plates 14, so that the rotating plates 14 are pushed by the pipe to rotate, the limiting block 15 and the limiting ring 16 are driven by the rotating plates 14 to turn and approach, when the limiting pin 17 contacts with the limiting ring 16, the limiting ring 16 pushes the limiting pin 17 to rotate inside the limiting block 15 through the inclined surface of the limiting pin 17, and compresses the return spring 18, after the limiting ring 16 completely strokes the limiting pin 17, the return spring 18 pushes the limiting pin 17 to return, and at this time, the limiting pin 17 is blocked by the limiting ring 16, so that the two sets of rotating plates 14 cannot reversely turn.

In order to further improve the convenience of disassembling and assembling the pipeline on the spring support and hanger, when the pipeline is required to be disassembled from the spring support and hanger, the push plate is pushed to drive the limiting pin 17 to rotate to compress the reset spring 18, then the pipeline can be hoisted by the existing hoisting equipment, and in the process, the two groups of rotating plates 14 lose the pushing of the weight of the pipeline, so that the two groups of rotating plates 14 reversely rotate and reset under the pushing of the torsion spring.

When the novel support device is used, the support spring 3 is creatively compressed, and the situation that two ends of the support spring 3 prop against the shell 1 is avoided, so that the shell 1 can be disassembled conveniently and safely in the overhaul process; in this scheme, drive carousel 7 through rotating pivot 9 and rotate, carousel 7 drives slip frame 6 through catch bar 8 and slides to thereby make two sets of pull rods 5 pulling two sets of extrusion heads 4 draw close to the centre and compress supporting spring 3, then rotate threaded rod 10 and drive slip tooth 11 and slide, make slip tooth 11 and fixed tooth 12 meshing, thereby let pivot 9 unable rotation, then can be light unpack shell 1, and avoided the upper cover of shell 1 to bounce and smash the operating personnel.

Although embodiments of the utility model have been shown and described, the detailed description is to be construed as exemplary only and is not limiting of the utility model as the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples, and modifications, substitutions, variations, etc. may be made in the embodiments as desired by those skilled in the art without departing from the principles and spirit of the utility model, provided that such modifications are within the scope of the appended claims.
