DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0024] As Figures 1-3 shown, a pipeline support device for thermal power plant transformation proposed by the present utility model, the base mechanism includes a base plate 11 and a support plate 13 stacked, and a plurality of counterweights 12 are arranged between the base plate 11 and the support plate 13;

[0025] The ring frame mechanism includes an outer ring member 31 disposed above the pallet 13. An inner ring member 33 is provided inside the outer ring member 31. The middle parts of the outer ring member 31 and the inner ring member 33 are connected by a vertical plate 32, and a plurality of spring members 34 are arranged in the gap.

[0026] The locking mechanism includes clamping plates 41 formed at the edge of the outer ring member 31. Two adjacent clamping plates 41 are connected by a clamping plate bolt 42. The end of the clamping plate bolt 42 passes through the base plate 11 and the bolt sleeve 43 installed on the pallet 13.

[0027] The chain locking mechanism includes locking grooves 51 formed on the clamping plates 41. A locking groove ring 53 is clamped in the locking groove 51. Two locking groove rings 53 are connected by a chain 52. Another locking groove ring 53 is connected to the angle seat 54.

[0028] It should be noted that: both the outer ring member 31 and the inner ring member 33 are semi-circular structures. A pipe is clamped between the two inner ring members 33. When supporting the pipe, the inner ring member 33 is attached to the pipe. At this time, the outer ring member 31 and the inner ring member 33 respectively form an inner ring and an outer ring. The inner ring is used for wrapping and limiting, and the outer ring is used for the installation of the locking mechanism.

[0029] In this embodiment, the basic reinforcement of the pipe after support is realized through the locking mechanism. One end of the clamping plate bolt 42 passing through the bolt hole on the clamping plate 41 is screwed into the bolt sleeve 43 installed on the base plate 11 and the pallet 13, and multi-point basic reinforcement of the combined ring frame is carried out at the corners of the base mechanism.

[0030] Through the design of the chain locking mechanism, the external reinforcement of the combined ring frame is increased. One locking groove ring 53 at one end of the chain 52 is connected to the locking groove 51, the chain 52 is pulled outwards to be tightened, and the other locking groove ring 53 is connected to the angle seat 54. The angle seat 54 is fixed on the ground, and then the chain 52 can be pulled outwards. At this time, the chain 52 forms an inclined structure with an inclination angle of 45°, increasing the stress points of the combined ring frame and improving the installation stability of the ring frame.

[0031] It should be added that a screw hole is formed at the bottom of the angle seat 54, and a locking bolt is installed in the screw hole.

[0032] In order to improve the seismic and shock resistance performance of the pipe, further, a rubber support block 2 is arranged in the gap between the outer ring member 31 and the pallet 13. The rubber support block 2 is an elastic member. The upper part of the rubber support block 2 is in direct contact with the outer ring member 31, and the rubber support block 2 disperses the downward gravity, solving the problem of single-point stress on the pallet 13.

[0033] It can be understood that since a spring member 34 is arranged between the inner ring and the outer ring, and the spring member 34 is a deformation structure, it can conduct the impact force of external shocks through it and release the impact force through elastic deformation, thus improving the seismic and shock resistance performance.

[0034] For the convenience of heat dissipation of the pipeline, further, a cavity is left between the outer ring member 31 and the inner ring member 33. The cavity is a through structure, and heat exchange of the pipeline is carried out through the cavity to prevent the inner ring covering the outer wall of the pipeline from hindering heat dissipation.

[0035] As Figure 4 shown, pull up the two groups of chains on the opposite sides to fix the angle seat 54 at a high position, so that the chains form an "X-shaped" structure, and the force is dispersed along the four angles facing the outside to improve the installation stability of the ring frame.

[0036] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
