[0002] With the rapid development of modern industry, industrial furnaces, as an indispensable and important equipment in the manufacturing industry, play a vital role. Whether it is metal smelting, ceramic firing, or heat treatment, heat treatment and other processes, they are inseparable from efficient and stable industrial furnaces. There are many types of industrial furnaces. According to their uses, they can be divided into melting furnaces, heating furnaces, heat treatment furnaces, etc., and according to heat sources, they can be divided into electric furnaces, gas furnaces, oil furnaces, etc. These industrial furnaces have their own characteristics and are suitable for different industrial production needs. For example, melting furnaces are mainly used for melting metals and preparing alloys, heating furnaces are widely used in material heat treatment, forging, welding and other processes, and heat treatment furnaces are mainly used to improve the properties of materials, such as quenching, annealing, tempering, etc. The traditional furnace top hanging device is not equipped with a buffer protection structure, which leads to excessive gravity at the moment the lifting rope is lifted and subjected to force, which can easily cause the lifting rope to break, posing serious safety hazards and having certain disadvantages.

[0003] In summary, the utility model solves the existing problems by designing a furnace top hanging device with a protective structure. Utility Model Content

[0007] Fixed plates are symmetrically installed at both ends of the bottom of the support plate and inside the through groove, a cross plate is installed between the bottoms of the fixed plates, a second connecting rod is installed at the four corners of the bottom of the cross plate, an electric telescopic rod is installed at the center of the bottom of the cross plate, a fixed block is installed at the bottom of the electric telescopic rod, and movable plates are symmetrically installed on the wider two sides of the outside of the fixed block, and a limiting clamp is installed at one end of the bottom of the movable plate.

[0008] As a preferred solution of the present invention, two groups of first damping rods are provided, and the first damping rods support the support plate through the connecting block. When the support plate is raised and lowered, the two fixed plates are raised and lowered synchronously inside the through groove, and the fixed plates do not contact the inside of the through groove.

[0009] As a preferred solution of the present invention, the outer side surface of the slider is slidably connected to the inner side wall of the sliding groove, and the outer side surface of the slider is fixedly connected to the first damping rod.

[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] For examples, see Figure 1-5 , the utility model provides a technical solution:

[0026] A furnace roof hanging device with a protective structure comprises a support base 1, support frames 2 are symmetrically installed at both ends of the top of the support base 1, a cross bar 3 is installed between the outer sides of the support frame 2, a lifting ring 4 is installed on the top of the cross bar 3, a through slot 101 is provided at the center position of the top of the support base 1, a first damping rod 5 is symmetrically installed at the two longer edges of the top of the support base 1, a connecting block 6 is installed on the top of the first damping rod 5, a support plate 7 is installed between the outer sides of the connecting block 6 and above the through slot 101, a base 8 is symmetrically installed at the two shorter edges of the top of the support base 1, a slide groove 801 is symmetrically opened at both ends of the top of the base 8, a second damping rod 9 is installed on one side wall of the inner side of the slide groove 801, a slider 10 is installed at one end of the second damping rod 9 and inside the slide groove 801, and a first connecting rod 11 is installed on the top of each slider 10;

[0027] Fixed plates 12 are symmetrically installed at both ends of the bottom of the support plate 7 and inside the through groove 101. A cross plate 13 is installed between the bottoms of the fixed plates 12. Second connecting rods 14 are installed at the four corners of the bottom of the cross plate 13. An electric telescopic rod 15 is installed at the center of the bottom of the cross plate 13. A fixed block 16 is installed at the bottom of the electric telescopic rod 15. Movable plates 17 are symmetrically installed on the wider two sides of the outside of the fixed block 16. A limiting clamp 18 is installed at one end of the bottom of the movable plate 17.

[0028] Specifically, refer to Figure 2 、 Figure 3 and Figure 5 The bottom end of the first connecting rod 11 is rotatably connected to the top of the slider 10, and the top end of the first connecting rod 11 is rotatably connected to the bottom of the support plate 7, thereby ensuring that when the support plate 7 is forced downward, the four groups of first connecting rods 11 drive the slider 10 to move inside the slide groove 801 and squeeze the first damping rod 5. The first damping rod 5 thereby applies a reaction force to the support plate 7, thereby buffering the support plate 7, avoiding the risk of the support plate 7 being forced downward without buffering, resulting in the rope on the lifting ring 4 being subjected to excessive gravity at the moment, which may easily cause the rope to break.

[0029] Furthermore, two groups of first damping rods 5 are provided, and the first damping rods 5 support the support plate 7 through the connecting block 6. When the support plate 7 is raised and lowered, the two fixed plates 12 are raised and lowered synchronously inside the through groove 101, and the fixed plates 12 do not contact the inside of the through groove 101, thereby ensuring that the two groups of first damping rods 5 play an auxiliary buffering role on the support plate.

[0030] Furthermore, the outer side surface of the slider 10 is slidably connected to the inner wall of the slide groove 801, and the outer side surface of the slider 10 is fixedly connected to the first damping rod 5, thereby ensuring that the slider 10 moves inside the slide groove 801 and squeezes the first damping rod 5. The sliding connection and tight fit between the outer side surface of the slider 10 and the inner wall of the slide groove 801 increase the stability of the movement of the slider 10.

[0031] Furthermore, four groups of second connecting rods 14 are provided, and the top ends of the four second connecting rods 14 are rotatably connected to the four corners of the bottom of the horizontal plate 13, and the bottom ends of the four second connecting rods 14 are rotatably connected to the top ends of the two movable plates 17 away from the fixed block 16, respectively, thereby ensuring that the fixed block 16 drives the two movable plates 17 to move when the fixed block 16 is raised and lowered to adjust the angle, and the four groups of second connecting rods 14 are driven to move synchronously by the arrangement of four groups of second connecting rods 14. The stability of the clamping and limiting of the industrial furnace for the angle adjustment of the two movable plates 17 is increased by providing four groups of second connecting rods 14.

[0032] For details, please refer to Figure 3 The two sides of the fixed block 16 are respectively rotatably connected to one end of the two movable plates 17. When the electric telescopic rod 15 contracts, the angle between the two movable plates 17 gradually decreases and approaches each other. When the electric telescopic rod 15 extends, the angle between the two movable plates 17 gradually increases and moves away from each other, thereby ensuring that when the electric telescopic rod 15 drives the fixed block 16 to rise and fall, the two movable plates 17 are synchronously driven to adjust the angle, and the two limit clamps 18 are used to facilitate the clamping and limiting of the industrial furnace.

[0033] The working process of the utility model: using a furnace top hanging device with a protective structure designed by the present invention, in the process of hanging and moving the industrial furnace, first, the electric telescopic rod 15 drives the fixed block 16 to be lifted and lowered, and simultaneously drives the two movable plates 17 to adjust the angle, and the two limit clamps 18 are used to facilitate the clamping and limiting of the industrial furnace. When the electric telescopic rod 15 contracts, the angle between the two movable plates 17 gradually decreases and approaches each other. When the electric telescopic rod 15 extends, the angle between the two movable plates 17 gradually increases and moves away from each other. When the fixed block 16 is lifted and lowered to drive the two movable plates 17 to adjust the angle, it simultaneously drives the four groups of second connecting rods 14 to move. By setting four groups of second connecting rods 14, the two movable plates 17 are increased to adjust the angle, and the stability of the clamping and limiting of the industrial furnace is improved. The lifting rope is connected to the external lifting equipment through the lifting ring 4. When the lifting rope pulls the lifting ring 4 to rise, the weight of the industrial furnace will cause the support plate 7 to drop. When the support plate 7 is forced downward, the four groups of first connecting rods 11 drive the corresponding slider 10 to move inside the slide groove 801 and squeeze the first damping rod 5. The first damping rod 5 thereby applies a reaction force to the support plate 7, thereby buffering the support plate 7 and avoiding the risk of the lifting rope on the lifting ring 4 being subjected to excessive gravity at the moment when the support plate 7 is forced downward without buffering, which may easily cause the risk of the lifting rope breaking. The sliding connection and tight fit between the outer side surface of the slider 10 and the inner side wall of the slide groove 801 increase the stability of the movement of the slider 10, and the two groups of first damping rods 5 play an auxiliary buffering role on the support plate 7, thereby playing a certain protective role.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
