Description

Technical Field

[0001] This utility model relates to the field of disassembly technology, specifically to an auxiliary device for disassembling a boiler burner. Background Technology

[0002] Boilers are widely used energy conversion devices in industrial production. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. The hot water or steam produced in the boiler can directly provide the heat energy needed for industrial production and daily life, or it can be converted into mechanical energy through a steam power unit, or further converted into electrical energy through a generator. The burner, as the core component of the boiler, is usually installed on the outside of the boiler end, and there is a certain distance between the burner and the ground. When the burner needs to be disassembled or assembled during boiler maintenance, an auxiliary support frame must be used for support.

[0003] A review of utility model publication CN 203249234U reveals a multi-functional burner frame, comprising a lifting frame, a movable fixing clamp, and a movable support base. Four wheels are evenly distributed at the bottom of the lifting frame for movement, and a fixed support base is connected to the center of the bottom of the lifting frame for securing its movement. This allows for installation or disassembly with the assistance of only two people, facilitating burner replacement and maintenance, increasing automation, and reducing manpower. While this device supports the burner during assembly and disassembly, a drawback in practical use is that during installation, the burner must be placed on a top plate. To ensure the burner's flange aligns with the boiler's flange, the burner needs to be moved on the top plate. However, the burner's weight makes this movement difficult. To overcome this drawback, this utility model provides an auxiliary device for boiler burner disassembly. Summary of the Invention

[0004] The purpose of this utility model is to provide an auxiliary device for disassembling a boiler burner, so that the burner can be easily moved on the device, thereby enabling the flange of the burner to fit properly with the flange of the boiler during installation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An auxiliary device for disassembling a boiler burner includes a base plate and a lifting plate. A fork-shaped lifting mechanism is provided between the base plate and the lifting plate. The fork-shaped lifting mechanisms are connected by multiple rotating shafts. A first driving mechanism for pushing the rotating shafts to move linearly is provided on the base plate. A movable plate is slidably disposed on the lifting plate. The movable plate moves along the length of the lifting plate and a supporting rotating seat is rotatably disposed on the movable plate. A second driving mechanism for pushing the movable plate to move linearly is disposed on the base plate.

[0006] Furthermore, the bottom of the base plate is provided with a support column and a moving wheel is provided at the bottom end of the support column, and a push rod is also provided on one side of the base plate.

[0022] refer to Figure 1-2 As shown, this utility model provides an auxiliary device for disassembling a boiler burner, including a base plate 1 and a lifting plate 8. A fork-shaped lifting mechanism 7 is provided between the base plate 1 and the lifting plate 8. The fork-shaped lifting mechanisms 7 are connected by multiple rotating shafts 15. A first driving mechanism for pushing the rotating shafts 15 to move linearly is provided on the base plate 1. Specifically, in order to adjust the height of the lifting plate 8 through the lifting mechanism 7, the connection relationship of the lifting mechanism 7 is as follows: the base plate 1 and the lifting plate 8 are provided with a rotating shaft support 5 and a rotating shaft sliding seat 6 on their opposite sides. The rotating shaft sliding seat 6 is provided with a sliding bar hole 61, which is arranged horizontally. Two rotating shafts 15 located on one side of the fork-shaped lifting mechanism 7 are rotatably connected to the rotating shaft support 5. Two rotating shafts 15 on the other side of the fork-shaped lifting mechanism 7 are inserted between the sliding bar holes 61, so that pushing the rotating shaft 15 on this side can realize the lifting process of the lifting mechanism 7.

[0023] refer to Figure 3 As shown, in some embodiments, the first driving mechanism includes a movable sleeve 13 and a first screw 14. The movable sleeve 13 has two through holes, one of which passes through the rotating shaft 15, and the other through hole through which a lead screw sleeve 131 passes. The first screw 14 is threaded into the lead screw sleeve 131. The first screw 14 is perpendicular to the rotating shaft 15, and its end is rotatably connected to the base plate 1. In practice, rotating the first screw 14 allows the rotating shaft 15 to move linearly along the sliding bar hole 61, thereby adjusting the lifting and lowering of the lifting plate 8.

[0024] A movable plate 10 is slidably disposed on the lifting plate 8. The movable plate 10 moves along the length direction of the lifting plate 8 and a supporting rotating seat 11 is rotatably disposed on the movable plate 10.

[0025] Specifically, the bottom of the movable plate 10 is provided with at least two sliding protrusions 101, and the lifting plate 8 is provided with a strip-shaped sliding hole 81. The sliding protrusions 101 pass through the strip-shaped sliding hole 81, thereby causing the movable plate 10 to move along the direction of the strip-shaped sliding hole 81.

[0026] In some embodiments, the second drive mechanism includes a second screw 16 and a screw seat 17. The screw seat 17 is fixedly disposed at the edge of the lifting plate 8 and has an internal threaded hole. The second screw 16 is threadedly connected in the internal threaded hole and the end of the second screw 16 is rotatably connected to the moving plate 10, so that the moving plate 10 can be moved back and forth by rotating the second screw 16. Controlling the back and forth movement of the burner by the second screw 16 is easier and less strenuous than moving it directly.

[0027] refer to Figure 4 As shown, to enable the rotatable configuration of the support rotating seat 11, a cylindrical boss 102 is provided at the center of the upper surface of the movable plate 10, and a plane bearing 18 is provided on the cylindrical boss 102. The middle part of the support rotating seat 11 is sleeved on the cylindrical boss 102 and contacts the plane bearing 18, thereby making the rotation more flexible. In order to enable the support rotating seat 11 to have high support strength, multiple annular protrusions are concentrically arranged on the bottom surface of the support rotating seat 11, among which the annular protrusion with the smallest diameter is sleeved on the cylindrical boss 102.

[0028] In addition, to facilitate the movement of the device, a support column 2 is provided at the bottom of the base plate 1 and a moving wheel 3 is provided at the bottom end of the support column 2. A push rod 12 is also provided on one side of the base plate 1.
