[0013] Figure 4 This is a schematic diagram of the structure of the present invention after the test furnace door is installed. Detailed Implementation

[0014] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1 to 4 As shown, a furnace door cleaning test door hook device includes a base 1 and a fixed column 2 installed on the base 1. A transverse frame 3 is slidably installed on the base 1. The transverse frame 3 is located on one side of the fixed column 2. A ring beam 4 is installed on the top of the transverse frame 3. The ring beam 4 is fitted onto the fixed column 2. A door hook structure is installed on the transverse frame 3. The door hook structure is used to install the test furnace door.

[0016] This utility model uses a base 1 and a fixed column 2 to form a fixed seat. A sliding transverse frame 3 is installed on the base 1. A door hook structure is installed on the transverse frame 3, which allows the installation of the test furnace door, facilitating cleaning tests of the furnace door. The door hook structure includes an offset frame 13, an offset cylinder 14, and a door hook 15. The transverse frame 3 is a frame structure, and fixed plates 16 are installed on both sides of the transverse frame 3. The offset frame 13 is installed inside the transverse frame 3, and its middle part is mounted on the fixed plate 16 via a rotating shaft 17. Door hooks 15 are installed on the upper and lower parts of the offset frame 13, respectively. An offset cylinder 14 is also installed on the side of the transverse frame 3, and the piston rod of the offset cylinder 14 is connected to the offset frame 3. The offset frame 13 is mounted on the transverse frame 3 via the rotating shaft 17, and the offset cylinder 14 can control the deflection of the offset frame 13.

[0017] The base 1 is equipped with a semi-circular track 5, and the bottom of the transverse frame 3 is equipped with a semi-circular grooved roller 6. The semi-circular grooved roller 6 is mounted on the semi-circular track 5, and a transverse movement cylinder 7 is also installed on one side of the semi-circular track 5. The piston rod of the transverse movement cylinder 7 is connected to the transverse frame 3. Through the cooperation of the semi-circular track 5 and the semi-circular grooved roller 6, it is possible to ensure that the semi-circular grooved roller 6 can deflect left and right relative to the semi-circular track 5. The inner diameter of the annular beam 4 is directly larger than the outer diameter of the fixed column 2, and a support roller 8 is installed between one side of the fixed column 2 and the annular beam 4, while an adjusting pad 9 is installed between the other side of the fixed column 2 and the annular beam 4. There is sufficient clearance between the annular beam 4 and the fixed column 2, which ensures that the transverse frame 3 has sufficient space, and the support roller 8 and adjusting pad 9 can position the transverse frame 3 after adjustment.

[0018] In addition, a wedge-tightening cylinder 10 is installed on the fixed column 2. A wedge-tightening block 11 is installed on the piston of the wedge-tightening cylinder 10. The wedge-tightening block 11 is located inside the annular beam 4, and a wedge-tightening seat 12 is installed on the outer wall of the fixed column 2 inside the annular beam 4. The wedge-tightening block 11 is installed on the wedge-tightening seat 12. The wedge-tightening cylinder 10 can control the wedge-tightening block 11 to snap into the wedge-tightening seat 12, thereby fixing the annular beam 4.

[0019] In practical use, after installing the test furnace door on the door hook structure of the horizontal movement frame 3, the wedge block 11 is first loosened by the wedge cylinder 10. Then, the horizontal movement frame 3 is pushed by the horizontal movement cylinder 7 to move slightly laterally. During this process, the mechanical furnace door cleaning device cleans the test furnace door, completing the horizontal movement test. Then, the horizontal movement cylinder 7 is reset. By adjusting the thickness of the adjusting shim 9, the test furnace door can achieve different pitch angles. During this process, the mechanical furnace door cleaning device cleans the test furnace door, completing the pitch test. Then, the adjusting shim 9 is fixed. The deflection frame 3 is deflected by the offset cylinder 14. During this process, the mechanical furnace door cleaning device cleans the test furnace door, completing the deflection test. Through continuous testing, the mechanical furnace door cleaning device is tested, which facilitates product improvement. After the test is completed, the wedge block 11 is tightened by the wedge cylinder 10 to complete the locking and fixing.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
