Description

Technical Field

[0001] This utility model relates to the field of pit-type carburizing furnace technology, and in particular to a fixed base for pit-type carburizing furnace. Background Technology

[0002] The pit-type carburizing furnace is a new type of energy-saving, cyclic-operation heat treatment electric furnace, mainly used for gas carburizing of steel parts. It has a single-chamber structure, with the furnace body constructed of high-grade refractory bricks. It employs a zoned heating design and uses a PID parameter-controlled power regulator to ensure uniform temperature and save energy. When machining the top of the pit-type carburizing furnace, most operators use ladders to stand directly on top, but the limited space at the top restricts operation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixed base for a pit-type carburizing furnace.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixed base for a pit-type carburizing furnace includes a main mounting frame on which a furnace body is mounted. A limiting protrusion for placing the furnace body is provided in the middle of the upper surface of the main mounting frame. Mounting columns are vertically installed at the four corners of the upper surface of the main mounting frame. Mounting top plates are horizontally installed on the top of the mounting columns. Multiple support plates are evenly arranged horizontally on the mounting top plates. Protective baffles are vertically inserted between the mounting columns on adjacent sides. A ladder is installed on the surface of one of the mounting columns with a larger area.

[0006] In addition, a preferred structure is that slots for installing protective baffles are vertically provided on both sides of the mounting column, and mounting holes are symmetrically provided on one of the mounting columns with a ladder installed.

[0007] In addition, a preferred structure is that each of the mounting columns is provided with a positioning column at the top, and a pull ring is fixedly connected to one side wall of the top of each mounting column.

[0008] In addition, in a preferred configuration, positioning holes for matching with positioning posts are provided at the four corners of the mounting top plate, and a first mounting groove and a second mounting groove are symmetrically provided on the upper surface of the mounting top plate, which are used to install the support plate.

[0009] Furthermore, in a preferred configuration, the support plate comprises a first plate and a second plate, wherein the area of ​​the first plate is larger than that of the second plate, and handles are symmetrically arranged on the first plate.

[0010] In addition, a preferred structure is that the top of the ladder is provided with a mounting plate for installation at the mounting hole, and multiple support columns are evenly arranged on both sides of the ladder frame in the vertical direction, and a top block is fixedly connected to each support column.

[0011] The beneficial effects of this utility model are as follows: The limiting protrusion in the middle of the main frame is embedded in the bottom of the furnace body, which effectively prevents the furnace body from shifting. The mounting top plate is connected to the positioning column through the positioning hole to ensure the installation accuracy of the top platform. The support plate is divided into a first plate and a second plate. The first and second mounting slots of the mounting top plate can be quickly disassembled and installed through the handle to form a customized work surface. It is also convenient for workers to stand up and complete the processing of the top of the pit carburizing furnace. The operating space for mounting the furnace body on the fixed base is larger.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-5A fixed base for a pit-type carburizing furnace includes a main frame 1, on which a furnace body 2 is mounted. A limiting protrusion 15 for placing the furnace body 2 is provided in the middle of the upper surface of the main frame 1. Mounting columns 12 are vertically arranged at the four corners of the upper surface of the main frame 1. A mounting top plate 3 is horizontally mounted on the top of the mounting column 12. Multiple support plates 4 are evenly arranged horizontally on the mounting top plate 3. Protective baffles 5 are vertically inserted between the mounting columns 12 on adjacent sides. A ladder 6 is installed on the surface of one of the mounting columns 12 with a larger area. The ladder 6 facilitates the operator to climb up.

[0020] The mounting column 12 has vertical slots 121 for installing protective baffles 5 on both sides of its sidewalls. One of the mounting columns 12 with a ladder 6 installed has symmetrical mounting holes 122. The protective baffles 5 provide good protection.

[0021] In addition, each of the mounting columns 12 is equipped with a positioning column 14 at the top, and a pull ring 13 is fixedly connected to one side wall of the top of each mounting column 12. The pull ring 13 facilitates the lifting of the main frame 1.

[0022] In addition, positioning holes 31 for matching with positioning posts 14 are provided at the four corners of the mounting top plate 3. The upper surface of the mounting top plate 3 is symmetrically provided with a first mounting groove 32 and a second mounting groove 33. The first mounting groove 32 and the second mounting groove 33 are used to install the support plate 4. The support plate 4 includes a first plate body 41 and a second plate body 42. The area of ​​the first plate body 41 is larger than that of the second plate body 42, and handles 43 are symmetrically provided on the first plate body 41. The support plate 4 is convenient for the operator to stand on.

[0023] Furthermore, the top of the ladder 6 is provided with a mounting plate 61 for installation at the mounting hole 122. Multiple support columns 62 are evenly arranged on both sides of the ladder 6 frame in the vertical direction, and a top block 63 is fixedly connected to each support column 62. The ladder 6 makes it easy for operators to climb up the top support plate 4.

[0024] In this embodiment, when the top of the pit-type carburizing furnace needs to be processed and assembled, the fixed base of this utility model can be used to complete the task. By hoisting the furnace body 2 onto the limiting protrusion 15, the operator installs the top plate 3 and then fastens the support plate 4 to each of the first mounting slots 32 and the second mounting slots 33. The operator can then climb up to the support plate 4 via the ladder 6 and complete the processing of the top of the furnace body 2 on the support plate 4. The protective baffle 5 can also play an effective protective role.

[0025] Furthermore, the support column 62 of the ladder 6, together with the top block 63, can effectively support the ladder 6 on the mounting column 12, preventing the ladder 6 from collapsing.

[0026] In this utility model, the limiting protrusion 15 in the middle of the main frame 1 is embedded in the bottom of the furnace body 2 to effectively prevent the furnace body from shifting. The mounting top plate 3 is inserted into the positioning column 14 through the positioning hole 31 to ensure the installation accuracy of the top platform. The support plate 4 is divided into a first plate 41 and a second plate 42. The first mounting slot 32 and the second mounting slot 33 of the mounting top plate 3 can be quickly disassembled and installed through the handle 43 to form a customized work surface, which is convenient for workers to stand up and complete the processing of the top of the pit carburizing furnace.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
