Description

Technical Field

[0001] This utility model relates to the technical field of sliding supports for boiler connection structures, and in particular to a sliding support for a boiler connection structure used to connect steel beams and boiler steel frames. Background Technology

[0002] In power generation projects, the coal bunker and boiler steel frame of the main plant of thermal power plants are designed by different design units and are two independent structures. However, according to process requirements, a connecting platform is needed between the two in the operating layer and other parts to facilitate operation. When the staff connects the two, the sliding support of the boiler connection structure used to connect the steel beam and the boiler steel frame is often used.

[0003] A sliding support for a boiler connection structure, used to connect steel beams and boiler steel frames, disclosed in publication number CN212535261U, includes a first connecting plate and a second connecting plate. The first connecting plate has a rectangular slot at its top. The top of the second connecting plate is fixedly connected to the bottom of a sliding guide rail. The inner walls of both sides of the sliding guide rail contact the bottom ends of a T-shaped sliding rod. The top of the T-shaped sliding rod extends through the rectangular slot on the first connecting plate and is fixedly connected to the bottom of a pad. The inner wall of the rectangular slot is fixedly connected to the left side of a left sliding plate, and the inner wall of the left sliding plate contacts the left side of a sliding plate. This sliding support for a boiler connection structure, used to connect steel beams and boiler steel frames, generates a first buffering effect by the sliding of the T-shaped sliding rod, which compresses a first buffer spring. The sliding plate also generates a second buffering effect by the pressure plate, which compresses a left moving rod and a second buffer spring. Simultaneously, the pressure plate also compresses a right moving rod and a second buffer spring.

[0004] However, this sliding support used to connect steel beams and boiler steel frames has the following disadvantages: the preload force on the buffer spring is small during use, its buffering method is relatively simple, and the buffering capacity of the buffer spring gradually decreases when the use time is too long, resulting in a shortened service life and affecting subsequent work efficiency. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a sliding support for connecting steel beams and boiler steel frames that is highly practical, easy to operate, and has a simple structure. This solves the problems mentioned in the background art, such as the small preload force on the buffer spring during use, the relatively simple buffering method, and the gradual reduction in the buffering capacity of the buffer spring over a long period of use, which leads to a shortened service life and affects subsequent work efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a sliding support for connecting steel beams and boiler steel frames, comprising a base, a buffer assembly on the top surface of the base, a polytetrafluoroethylene plate on the top of the buffer assembly, a mirror steel plate overlapping the top surface of the polytetrafluoroethylene plate, a silicone grease layer applied to the top surface of the mirror steel plate, and grooved rods welded to both sides of the base.

[0007] Optionally, the buffer assembly includes a first flexible rubber sheet, the bottom of which overlaps the middle of the top surface of the base, a thin steel plate overlaps the top surface of the first flexible rubber sheet, and a second flexible rubber sheet overlaps the top of the thin steel plate.

[0008] Optionally, the inner top wall of the grooved rod is engaged with both sides of the top surface of the mirror steel plate, and the number of grooved rods is four.

[0009] Optionally, a reinforcing plate is fixedly installed at the bottom of the first flexible rubber sheet, and reinforcing ribs are embedded at equal intervals inside the reinforcing plate.

[0010] Optionally, threaded holes are provided on both sides of the top surface of the base, and a fixed cone is passed through the internal thread of the threaded hole.

[0011] Optionally, welding strips are provided on both sides of the bottom of the base, and a counterweight is provided in the middle of the bottom of the base.

[0012] This utility model provides a sliding support for a boiler connection structure that connects steel beams and boiler steel frames, which has the following advantages:

[0013] 1. The sliding support for the boiler connection structure used to connect the steel beam and the boiler steel frame, through the setting of the buffer component and the base, when the base is subjected to greater pressure during use, the pressure is transmitted along the mirror steel plate to the interior of the second flexible rubber plate. Subsequently, the second flexible rubber plate, together with the thin steel plate and the first flexible rubber plate, causes the first and second flexible rubber plates to be squeezed and deformed, thereby reducing the pressure and improving the buffering performance of the base.

[0014] 2. The sliding support of the boiler connection structure used to connect the steel beam and the boiler steel frame, through the setting of polytetrafluoroethylene plate, buffer component and mirror steel plate, can shift left and right with the vibration of the boiler during the operation of the boiler, thereby improving the vibration damping of the boiler and reducing the occurrence of boiler damage caused by severe vibration during the operation of the boiler.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a sliding support for connecting steel beams and boiler steel frames, including a base 1, a buffer assembly 2 on the top surface of the base 1, the buffer assembly 2 including a first flexible rubber plate 21, the bottom of the first flexible rubber plate 21 overlapping the middle of the top surface of the base 1, the top surface of the first flexible rubber plate 21 overlapping a thin steel plate 22, and the top of the thin steel plate 22 overlapping a second flexible rubber plate 23.

[0022] With the buffer assembly 2 and the base 1 in place, when the base 1 is subjected to a large pressure during use, the pressure is transmitted along the mirror steel plate 4 to the interior of the second flexible rubber plate 23. Subsequently, the second flexible rubber plate 23, together with the thin steel plate 22 and the first flexible rubber plate 21, causes the first flexible rubber plate 21 and the second flexible rubber plate 23 to be squeezed and deformed, thereby reducing the pressure and improving the buffering performance of the base 1.

[0023] Please see Figure 3 The top of the buffer assembly 2 is provided with a polytetrafluoroethylene plate 3, and the top surface of the polytetrafluoroethylene plate 3 is overlapped with a mirror steel plate 4, and the top surface of the mirror steel plate 4 is coated with a layer of silicone grease.

[0024] With the installation of polytetrafluoroethylene plate 3, buffer component 2 and mirror steel plate 4, the mirror steel plate 4 can shift left and right with the vibration of the boiler during the operation of the boiler, thereby improving the vibration damping of the boiler and reducing the occurrence of boiler damage caused by severe vibration during operation.

[0025] Please see Figure 2 The base 1 has four grooved rods 5 welded on both sides. The inner top wall of the grooved rod 5 is engaged with both sides of the top surface of the mirror steel plate 4.

[0026] By setting the grooved rod 5, during the sliding damping process of the base 1, the grooved rod 5 integrates and limits the mirror steel plate 4.

[0027] Please see Figures 1 to 4 A reinforcing plate 6 is fixedly installed at the bottom of the first flexible rubber plate 21. Reinforcing ribs 7 are embedded at equal intervals inside the reinforcing plate 6. Welding strips 9 are provided on both sides of the bottom of the base 1. A counterweight block 10 is provided in the middle of the bottom of the base 1.

[0028] By setting the reinforcing plate 6 and the reinforcing rib 7, when the base 1 is used for too long, the reinforcing plate 6 and the reinforcing rib 7 can enhance the toughness of the base 1 and improve the service life of the base 1.

[0029] By adding counterweight 10, the weight of base 1 is increased, thereby improving the stability of base 1;

[0030] Please see Figure 1 Both sides of the top surface of the base 1 are provided with threaded holes, and the internal threads of the threaded holes are penetrated by a fixing cone 8;

[0031] With the setting of the fixing cone 8, during the process of the worker installing the base 1, the fixing cone 8 can be used to fix the base 1 to the designated working position, thereby facilitating the installation of the base 1 by the installer.

[0032] In this invention, the working steps of the device are as follows:

[0033] When workers use the sliding support of the boiler connection structure, they first use the fixed cone 8 to install the base 1 to the designated working position, and then use it with the welding rod 9. Afterwards, workers can install the sliding support of the boiler connection structure between the boiler and the steel beam. During the operation of the boiler, when vibration occurs, the pressure is transmitted along the mirror steel plate 4 to the interior of the second flexible rubber plate 23. Then, under the combined action of the second flexible rubber plate 23, the thin steel plate 22, and the first flexible rubber plate 21, the first flexible rubber plate 21 and the second flexible rubber plate 23 are squeezed and deformed. As the pressure is reduced, the mirror steel plate 4 can shift left and right with the boiler vibration, which improves the vibration damping of the boiler and reduces the occurrence of boiler damage caused by severe vibration during operation.
