Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a boiler furnace bottom supporting device. Background Art

[0002] A boiler is an energy conversion device. Energy input to the boiler includes chemical energy from fuel and electrical energy, and the boiler outputs a certain amount of thermal energy in the form of steam, high-temperature water, or an organic heat carrier. The original meaning of "pot" refers to a container for holding water heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main components: the pot and the furnace. The hot water or steam produced by the boiler can directly provide heat energy for industrial production and daily life. It can also be converted into mechanical energy through a steam power plant, or further converted into electrical energy through a generator. The bottom of the boiler typically requires a support structure to support the boiler and provide protection and stability.

[0003] Currently, the support device used for the bottom of the boiler is usually directly welded to the bottom of the boiler through a fixed metal frame to achieve the function of supporting stability. However, the welded base support frame cannot adjust its support range, which makes the adaptability of this type of base support frame poor and cannot be adjusted to barrel-shaped boilers of different sizes and types. Therefore, a boiler bottom support device is proposed to solve the above problem. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a boiler furnace bottom support device, which has a base support suitable for different types of barrel-shaped boilers, and has a wide support surface and good support stability.

[0005] The utility model provides a boiler furnace bottom support device, comprising two support frames, a base plate connected between the tops of the two support frames, two connecting support plates connected in the middle of the two support frames, and the two connecting support plates are respectively arranged on the left and right sides of the two support frames, four hinged seats are fixedly installed on the top of the base plate, the four hinged seats are hinged to one end of the arc-shaped steel frame, the other ends of the four arc-shaped steel frames are fixedly installed with a hinged frame, the four hinged frames are hinged to one end of the electric push rod, the other ends of the four electric push rods are movably installed on the top of the two connecting support plates, the four arc-shaped steel frames are divided into two groups, and the top of each group of the arc-shaped steel frames is laid with an arc-shaped support plate.

[0006] Preferably, a connecting rod is connected between each group of the arc-shaped steel frames, the top of the arc-shaped support plate is adapted to barrel-type boilers of different sizes and types, and both ends of the base plate are inserted into the opposite side surfaces of the two support frames.

[0007] Preferably, the bottom of the arc-shaped support plate is welded to the top of each group of the arc-shaped steel frames, and a control box for controlling the synchronous start-up of the four electric push rods is provided on the support frame.

[0008] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0009] The boiler furnace bottom support device uses an electric push rod to support the lifting of one end of the arc-shaped steel frame to change the height of one side of the two arc-shaped support plates, so that the arc-shaped support plates can adapt to the furnace walls of various barrel-shaped boilers, thereby improving the adaptability of the base support frame. At the same time, the width of the arc-shaped support plates increases the contact with the boiler, thereby improving the stability of the support device and the boiler.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0017] like Figure 1-3 As shown, the utility model proposes a boiler furnace bottom support device, including two support frames 1, which are supported by the ground and are composed of two ground support feet and an isosceles trapezoidal block on the top. A base plate 2 is connected between the tops of the two support frames 1, which mainly serves as a long plate-shaped support plate for supporting the boiler. Two connecting support plates 3 are connected in the middle of the two support frames 1. The long metal strips are arranged on the left and right sides of the two support frames 1 respectively. Four hinge seats 8 are fixedly installed on the top of the base plate 2. 8 are hinged to one end of the arc-shaped steel frame 4, the arc-shaped steel frame 4 can adapt to the curvature of the outer wall of the boiler, and serve as the main supporting structure for the boiler. The other ends of the four arc-shaped steel frames 4 are fixedly installed with an articulated frame 5, and the four articulated frames 5 are hinged to one end of the electric push rod 9, which serves as the power source for adjusting the arc-shaped steel frame 4. The other ends of the four electric push rods 9 are movably installed on the top of the two connecting support plates 3. The four arc-shaped steel frames 4 are divided into two groups, and the top of each group of arc-shaped steel frames 4 is laid with an arc-shaped support plate 7, which is used to support the arc-shaped metal plate of the boiler furnace wall.

[0018] In an optional embodiment, a connecting rod 6 is connected between each group of arc-shaped steel frames 4, the top of the arc-shaped support plate 7 is adapted to barrel-type boilers of different sizes and types, and the two ends of the base plate 2 are inserted into the opposite side surfaces of the two support frames 1.

[0019] It should be noted that the connecting rod 6 connects the two sets of arc-shaped steel frames 4 to strengthen their stability.

[0020] In an optional embodiment, the bottom of the arc-shaped support plate 7 is welded to the top of each group of arc-shaped steel frames 4, and a control box for controlling the synchronous start-up of the four electric push rods 9 is provided on the support frame 1.

[0021] It should be noted that the control box contains a control system for controlling the boiler, including control of the electric push rod 9 .

[0022] Specifically, when a supporting device is needed to support the boiler, the barrel-shaped boiler can be pulled up by a lifting device and placed between the two arc-shaped support plates 7. The two arc-shaped support plates 7 are then adjusted according to the size of the boiler barrel diameter. The electric push rod 9 needs to be started to squeeze the arc-shaped steel frame 4, so that the arc-shaped steel frame 4 lifts up one side of the top of the arc-shaped support plate 7 so that the arc-shaped support plate 7 is completely consistent with the boiler furnace wall, thereby achieving the purpose of adapting to barrel-shaped boilers of different sizes.

[0023] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
