Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature pit furnaces, and particularly relates to a high-temperature pit furnace with an assembled suspension structure. Background Technique

[0002] The high-temperature pit furnace is a periodic operation furnace, which is suitable for the heat treatment of rod-shaped and long-axis parts. Its structure includes a cylindrical furnace body, and the workpiece is vertically loaded into the furnace for heating by a special crane. The high-temperature pit furnace can use gas or liquid fuel, or can be electrically heated. When using gas fuel, usually multiple small-energy burners are installed along the tangent direction of the inner wall of the furnace chamber to avoid the direct scouring of the flame on the workpiece and ensure uniform temperature in the furnace; the high-temperature pit furnace has a good application effect in the spherical treatment of carbide in steel, and a protective atmosphere often appears, so that the surface accuracy of the workpiece can be guaranteed after heat treatment, effectively ensuring the toughness and stiffness of the workpiece.

[0003] For a conventional high-temperature pit furnace, its furnace cover needs external equipment for hoisting and moving to realize combination or separation with the furnace body. Therefore, a suspension structure on the furnace cover needs to be used, but the conventional suspension structure and the furnace cover itself adopt an integral structure, which is relatively limited in terms of convenience and flexibility in use, resulting in a certain degree of structural interference in maintaining the equipment.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a high-temperature pit furnace with an assembled suspension structure is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-temperature pit furnace with an assembled suspension structure to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-temperature pit furnace with an assembled suspension structure, including a furnace body assembly and a suspension frame assembly. A furnace cover assembly is installed at the top of the furnace body assembly, and a locking assembly is installed around the furnace cover assembly. The suspension frame assembly is connected directly above the furnace cover assembly, and a fixed pile vertically penetrates through the middle of the suspension frame assembly. The suspension frame assembly includes an annular frame, a suspension bracket, a movable frame, and a hook. Four suspension brackets are installed at the top edge of the annular frame in a circular array with the annular frame as the center, and six movable frames are installed on the bottom surface of the annular frame in a circular array with the annular frame as the center. Moreover, one end of the movable frame away from the annular frame is connected with a hook.

[0007] Furthermore, the furnace body assembly includes a high-temperature pit-type furnace body, a limiting ring, a positioning pile and a sealing ring. A limiting ring is arranged on the top of the high-temperature pit-type furnace body, and the side of the limiting ring is connected to the positioning pile, and a sealing ring is installed on the surface of the limiting ring away from the positioning pile.

[0008] Furthermore, the positioning piles are fixedly connected to the limiting ring, and six groups of positioning piles are installed in a circular array with the limiting ring as the center.

[0009] Furthermore, the furnace cover assembly includes a furnace cover body, connecting piles, a fixing seat and hanging ears. The sides of the furnace cover body are connected with connecting piles in a circular array with the furnace cover body as the center, and six groups are arranged. A fixing seat is installed in the middle of the top of the furnace cover body, and the top edge of the furnace cover body is connected with hanging ears in a circular array with the furnace cover body as the center, and six groups are arranged.

[0010] Furthermore, the locking assembly includes a track column, a lifting slider, a servo motor and a fastening screw. The lifting slider is slidably installed on the surface of the track column, and the servo motor is vertically installed on the side of the lifting slider away from the track column, and the bottom power output end of the servo motor is vertically installed with a fastening screw through a coupling.

[0011] Furthermore, the connecting pile and the positioning pile are connected to each other by an inserting structure, and the connecting pile and the positioning pile are both threadedly connected to the fastening screw.

[0012] Furthermore, the fixing pile comprises a connecting pile, a lifting ring and a fixing ring. The top of the connecting pile is connected with the lifting ring, and the middle section of the connecting pile is connected with the fixing ring.

[0013] Furthermore, the connecting piles are respectively connected to the annular frame, the fixing seat and the lifting ring by threads, and the connecting piles and the lifting ring are connected by welding.

[0014] The utility model provides a high-temperature pit furnace with an assembled suspension structure, which has the following beneficial effects:

[0015] 1. In this utility model, a suspension frame assembly and a fixing pile are provided. By utilizing the structural mobility of the movable frame, the hook and the hanging ear are hooked to each other. Then, the connecting pile is screwed vertically into the middle of the annular frame, and the lower end of the connecting pile is further screwed into the fixing seat. At the same time, a fixing ring is used to further fix the connecting pile and the annular frame. By using the above structure, through the connection and assembly of the suspension frame assembly, it is convenient for external equipment to hoist and move the furnace cover assembly, so that the workpiece materials to be processed can be taken out or put into the furnace body assembly easily, avoiding structural interference. At the same time, the suspension frame assembly and the furnace cover assembly are connected and fixed to each other by the fixing pile, which not only enables the two structures to have flexible and convenient structural disassembly, but also the four groups of hanging frames arranged at the top of the annular frame can ensure that when the external equipment hoists the furnace cover assembly through the suspension frame assembly, it has sufficient firmness and stability.

[0016] 2. In this utility model, six locking components are annularly arranged at the edge of the furnace cover assembly. At the same time, in cooperation with the connecting piles annularly distributed on the side of the furnace cover body and the positioning piles annularly distributed on the side of the limiting ring, when the furnace cover assembly is covered on the top of the furnace body assembly vertically from top to bottom, the connecting piles will be vertically inserted into the positioning piles. At the same time, the lifting slider will drive the servo motor to move vertically along the surface of the track column, and the servo motor will drive the fastening screw installed at the bottom to rotate axially vertically, so that it can be screwed into the connecting piles and the positioning piles in turn. By using the above structure, the quick locking or structural separation between the furnace body assembly and the furnace cover assembly can be realized, avoiding the time-consuming and laborious problem of manual operation, and also avoiding the emergence of unnecessary safety hazards, providing a certain degree of safety protection for the operators.
