Description

Technical Field

[0001] This utility model relates to the field of steel shell furnace technology, and in particular to a steel shell furnace frame with oil pipes concealed inside. Background Technology

[0002] A steel-shell furnace is a heating device with a steel shell as its core structure. It is widely used in industrial production (such as chemical, metallurgical, and building materials), commercial heating, and small heating stations. Its core function is to transfer heat to the medium (water, air, process fluids, etc.) by burning fuel (oil, gas, biomass, etc.) or electric heating elements to meet the needs of heating, warming, and process reactions.

[0003] In traditional steel-shell furnaces, the hydraulic pipes used to supply hydraulic oil to the tilting cylinders are arbitrarily installed on the outside of the furnace frame. These external hydraulic pipes are not protected by any shell, making them very susceptible to deformation and rupture due to impacts from external objects, resulting in low safety. Moreover, steel-shell furnaces are mostly used in high-temperature environments such as steel plants and foundries, and the hydraulic pipes are also prone to rupture due to prolonged direct exposure to high temperatures, greatly increasing the risk of hydraulic oil leakage. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a steel shell furnace frame with concealed hydraulic oil pipes, which protects the hydraulic oil pipes by concealing them inside the furnace frame, thereby improving the safety of the hydraulic oil pipes and significantly reducing the risk of hydraulic oil leakage.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An internally mounted steel furnace frame includes a furnace frame body and a tilting cylinder for driving the furnace frame body to tilt. The lower end of the furnace frame body is provided with a square base frame. The three side walls of the square base frame are respectively provided with a first mounting cavity, a second mounting cavity, and a third mounting cavity. The first mounting cavity, the second mounting cavity, and the third mounting cavity are equipped with hydraulic oil circuits for supplying oil to the tilting cylinder. The first mounting cavity is provided with a mounting component for fixing the hydraulic oil circuit. The inlet and outlet ends of the hydraulic oil circuit are connected to the inlet and outlet ports of the tilting cylinder through oil delivery hoses. Protective plates are hinged to the openings of the first mounting cavity, the second mounting cavity, and the third mounting cavity. Multiple limiting components for limiting the free ends of the protective plates are fixed on the square base frame.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The limiting component includes a limiting block disposed on the outside of the protective plate. The limiting block is slidably mounted on the square base frame via a sliding rod, and a compression spring is installed between the sliding rod and the square base frame.

[0009] Further optimization: The hydraulic circuit includes a main oil supply pipe and two branch oil supply pipes. The main oil supply pipe and the branch oil supply pipes are arranged perpendicularly. The end of each branch oil supply pipe away from the main oil supply pipe is equipped with an inlet / outlet oil connector. The end of the oil supply hose away from the tilting cylinder is installed on the inlet / outlet oil connector.

[0010] Further optimization: The main oil pipeline is installed horizontally in the first mounting cavity, and two branch oil pipelines are respectively installed in the second and third mounting cavities. The ends of the branch oil pipelines near the main oil pipeline extend into the first mounting cavity and are respectively connected to both ends of the main oil pipeline.

[0011] Further optimization: The mounting assembly includes at least one pair of fixed half-seats and movable half-seats, which are arranged opposite to each other. The oil supply pipe passes through the cylindrical cavity formed between the fixed half-seats and the movable half-seats. The back of the fixed half-seat is fixed to the inner wall of the first mounting cavity. One end of the fixed half-seat is hinged to one end of the movable half-seat via a hinge shaft. A locking pawl is hinged to the other end of the fixed half-seat. A torsion spring is installed at the hinge point between the locking pawl and the fixed half-seat. A locking groove is provided on the outer wall of the other end of the movable half-seat, and the free end of the locking pawl is pressed into the locking groove.

[0012] The present invention adopts the above technical solution and has the following beneficial effects: The present invention adopts the above technical solution, which is ingenious in conception and reasonable in structure. The hydraulic oil circuit is hidden inside the furnace frame body, which avoids the hydraulic oil circuit being directly exposed to the high temperature casting environment for a long time. This not only reduces the risk of the hydraulic oil circuit being impacted by external objects and improves the safety of the hydraulic oil circuit, but also reduces the risk of hydraulic oil leakage by eliminating the need to directly expose the hydraulic oil circuit to the high temperature environment.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown in the figure, a steel shell furnace frame with an internal oil pipe includes a furnace frame body 1 and a tilting cylinder 2 for driving the furnace frame body 1 to tilt.

[0020] In this embodiment, the connection relationship between the tilting cylinder 2 and the furnace frame body 1 and the tilting principle are both existing technologies and are well known to those skilled in the art, so they will not be described in detail here.

[0021] Preferably, the lower end of the furnace frame body 1 is provided with a square base frame 3, and the three side walls of the square base frame 3 are respectively provided with a first mounting cavity 301, a second mounting cavity 302 and a third mounting cavity 303.

[0022] In this embodiment, the first mounting cavity 301 is disposed on the front wall of the square base frame 3, and the second mounting cavity 302 and the third mounting cavity 303 are respectively disposed on the two side walls of the square base frame 3.

[0023] Furthermore, the second mounting cavity 302, the first mounting cavity 301, and the third mounting cavity 303 are connected in sequence.

[0024] Preferably, the first mounting cavity 301, the second mounting cavity 302 and the third mounting cavity 303 are equipped with hydraulic oil circuits 4 for supplying oil to the tilting cylinder 2. The first mounting cavity 301 is provided with a mounting assembly 5 for fixing the hydraulic oil circuit 4. The oil inlet and outlet ends of the hydraulic oil circuit 4 are connected to the oil inlet and outlet ports of the tilting cylinder 2 through oil delivery hoses 6. Protective plates 7 are hinged at the openings of the first mounting cavity 301, the second mounting cavity 302 and the third mounting cavity 303. Multiple limiting assemblies 8 for limiting the free ends of the protective plates 7 are fixed on the square base frame 3.

[0025] like Figure 1 and Figure 3 As shown in the figure, the limiting component 8 includes a limiting block 801 disposed on the outside of the protective plate 7. The limiting block 801 is slidably mounted on the square base frame 3 via a slide rod 802. A compression spring 803 is installed between the slide rod 802 and the square base frame 3.

[0026] In this embodiment, the limiting component 8 limits and blocks the free end of the protective plate 7, so as to completely enclose the oil hose 6 inside the square bottom frame 3, avoiding the hydraulic oil circuit from being directly exposed to the high temperature casting environment for a long time. This not only reduces the risk of the hydraulic oil circuit 4 being impacted by foreign objects and improves the safety of the hydraulic oil circuit 4, but also eliminates the need to directly expose the hydraulic oil circuit 4 to the high temperature environment, thus reducing the risk of hydraulic oil leakage.

[0027] When maintenance is required on oil pipeline 4:

[0028] First, the maintenance personnel raise the limit block 801 upwards. The limit block 801 drives the slide rod 802 to move upwards and compresses the compression spring 803 until the limit block 801 disengages from the protective plate 7. The maintenance personnel can then open the protective plate 7 outwards and release the limit block 801. The limit block 801 returns to its original position under the elastic force of the compression spring 803.

[0029] Afterwards, the maintenance personnel inspected the hydraulic oil circuit 4 located inside the square bottom frame 3. After the inspection was completed, the maintenance personnel raised the limit stop 801 again and rotated the protective plate 7 to close it.

[0030] Finally, the maintenance personnel released the limit block 801, which, under the elastic force of the compression spring 803, moved downward and pressed against the outer wall of the protective plate 7, thus limiting and fixing the free end of the protective plate 7.

[0031] like Figure 1 and Figure 2 As shown in the figure, the hydraulic circuit 4 includes a main oil supply pipe 401 and two branch oil supply pipes 402. The main oil supply pipe 401 and the branch oil supply pipes 402 are arranged perpendicularly. Each branch oil supply pipe 402 is equipped with an inlet / outlet connector 403 at the end away from the main oil supply pipe 401. The end of the oil supply hose 6 away from the tilting cylinder 2 is installed on the inlet / outlet connector 403.

[0032] The main oil pipeline 401 is installed horizontally in the first mounting cavity 301, and two branch oil pipelines 402 are respectively installed in the second mounting cavity 302 and the third mounting cavity 303. The end of each branch oil pipeline 402 near the main oil pipeline 401 extends into the first mounting cavity 301 and is connected to both ends of the main oil pipeline 401.

[0033] like Figure 1 and Figure 3 As shown, the mounting assembly 5 includes at least one pair of fixed half-seats 501 and movable half-seats 502. The fixed half-seats 501 and movable half-seats 502 are arranged opposite to each other. The oil supply pipe 401 passes through the cylindrical cavity formed between the fixed half-seats 501 and movable half-seats 502. The back of the fixed half-seat 501 is fixed to the inner wall of the first mounting cavity 301. One end of the fixed half-seat 501 is hinged to one end of the movable half-seat 502 through a hinge shaft 503. A locking claw 504 is hinged to the other end of the fixed half-seat 501. A torsion spring 505 is installed at the hinge point between the locking claw 504 and the fixed half-seat 501. A locking groove 506 is provided on the outer wall of the other end of the movable half-seat 502. The free end of the locking claw 504 is pressed into the locking groove 506.

[0034] After maintenance, the method for replacing hydraulic circuit 4 is as follows:

[0035] First, the maintenance personnel rotate the locking claw 504 downwards so that the free end of the locking claw 504 is disengaged from the movable half seat 502, and then the movable half seat 502 can be rotated outwards to open it.

[0036] Afterwards, the maintenance personnel removed the inlet and outlet ends of the two oil supply branch pipes 402 from the inlet and outlet connectors 403. Then, the maintenance personnel held the main oil supply pipe 401 and pulled it outwards. As the main oil supply pipe 401 moved outwards away from the square base frame 3, it also caused the oil supply branch pipes 402 to move outwards, and finally the entire hydraulic oil circuit 4 was separated from the square base frame 3.

[0037] Next, after inserting the new hydraulic oil circuit 4 into the square base frame 3, the main oil supply pipe 401 enters the half cavity of the fixed half seat 501, and then the locking claw 504 is rotated downwards again to avoid the locking claw 504 from obstructing the engagement of the movable half seat 502. After the movable half seat 502 is engaged, the oil supply branch pipe 402 is connected to the inlet and outlet oil connector 403.

[0038] Finally, fasten the protective plate 7 securely.

[0039] Based on the above description, the present invention has a simple structure and is easy to operate. Moreover, it does not require much modification to the entire steel shell furnace frame and can be processed and improved on the existing steel shell furnace frame, thereby reducing the cost of the present invention.

[0040] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
