Description

Technical Field

[0001] This utility model relates to the technical field of devices for cleaning debris in fire channels, and in particular to a device for cleaning debris in fire channels. Background Technology

[0002] In coke ovens that have been in use for a long time, the surface of the coke oven wall is subjected to long-term pressure from the coke pusher and the coke oven. This can cause the internal structure of the combustion chamber to loosen and bricks to fall off. Because the combustion chamber is a small space, the bottom lamp head bricks are often blocked by falling silica bricks, which can obstruct the gas passage, affect normal heating, and cause local immaturity of the coke, seriously affecting the heating regime.

[0003] The existing method involves using a long metal tube to extend from the inspection hole into the combustion chamber, aiming at one side of the brick, and moving the brick away from the lamp holder brick's position. This operation cannot remove the brick from the combustion chamber, and is extremely difficult due to the small diameter of the inspection hole. Utility Model Content

[0004] Therefore, it is necessary to provide a device for cleaning debris in the fire channel to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a device for cleaning debris in a fire channel, comprising a rotating rod and a handle. The rotating rod is rotatably mounted inside the handle, and a nut is installed at the bottom of the handle. The rotating rod is threadedly connected to the nut. Two telescopic rods are hinged to the handle, and the two telescopic rods are symmetrically arranged. A hinge rod is rotatably mounted on the telescopic rod, and a second telescopic rod is rotatably mounted on the hinge rod. The ends of the two second telescopic rods away from the hinge rod are hinged to the same nut. The rotating rod is threadedly connected to the nut. A clamp is installed at the output end of both the first and second telescopic rods.

[0006] Preferably, the second nut is installed inside the fixed ring, and the second telescopic rod is hinged to the fixed ring.

[0007] Preferably, the telescopic rod one and the telescopic rod two are arranged in two symmetrical sets, each set including two telescopic rods one and two telescopic rods two.

[0008] Preferably, the hinge rod is a long rod, and the two sets of telescopic rod one and telescopic rod two share two hinge rods.

[0009] Preferably, a plurality of stabilizing rings are installed inside the grip, and the rotating rod is rotatably slidably connected to the stabilizing rings.

[0010] Preferably, a handle is installed on the rotating rod.

[0011] Preferably, the grip bar is equipped with a handle.

[0012] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0013] By using the combination of the rotating rod and the grip rod, two symmetrical telescopic rods 1 and 2 can be driven to form a diamond telescopic frame, and with the help of nuts 1 and 2, they can extend and retract, thus conveniently clamping bricks and enabling timely cleaning when bricks fall into the combustion chamber, shortening maintenance time and reducing the workload of operators.

[0014] By using the combination of nut one and nut two, after the brick is clamped, the different thread directions of the two nuts together limit the rotation rod, so that the operator does not have to keep controlling the rotation rod to clamp the brick out.

[0015] By using two sets of symmetrically arranged telescopic rods, the gripping effect on bricks is improved. The large gripping area of ​​the two clamping blocks on each side makes it less likely for the bricks to fall after being gripped. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 3This application provides a device for cleaning debris in a fire channel, including a rotating rod 1 and a gripping rod 2. The rotating rod 1 is rotatably installed inside the gripping rod 2. A nut 3 is installed at the bottom of the gripping rod 2. The rotating rod 1 is threadedly connected to the nut 3. Two telescopic rods 4 are hinged to the gripping rod 2. The two telescopic rods 4 are symmetrically arranged. A hinged rod 5 is rotatably installed on the telescopic rod 4. A second telescopic rod 6 is rotatably installed on the hinged rod 5. The ends of the two second telescopic rods 6 away from the hinged rod 5 are hinged to the same nut 7. The rotating rod 1 is threadedly connected to the nut 7. A clamping block 8 is installed at the output end of both the first telescopic rod 4 and the second telescopic rod 6.

[0022] In this embodiment, the threads on nut 3 and nut 7 are opposite in direction. During operation, the operator holds the handle 2 and the rotating rod 1 to insert the entire device into the combustion chamber through the observation hole at the top of the combustion chamber. After the clamping block 8 at the bottom of the device reaches the vicinity of the brick, the relative distance between nut 3 and nut 7 on the rotating rod 1 is adjusted by rotating the rotating rod 1. This causes the telescopic rods 4 and 6 to bulge to both sides or retract together, thereby adjusting the opening and closing degree of the bottom of the two telescopic rods 6. After the clamping block 8 is located on both sides of the brick, the rotating rod 1 is quickly rotated to make nut 3 and nut 7... The increased distance between them allows the telescopic rods 4 and 6 to lengthen, enabling the ends of the two telescopic rods 6 to close together. This allows the clamping block 8 to hold the brick in place. If the brick is small, the tool can be quickly lifted to remove it. If the brick is large, it can be moved to a position that does not obstruct the airflow from the lamp holder brick. Then, the rotating rod 1 can be turned in the opposite direction to release the brick and quickly pull out the tool. The hinge rod 5 is designed to coordinate the opening and closing of the telescopic rods 4 and 6. The nuts 3 and 7 allow for faster retraction and expansion compared to a single nut.

[0023] In some embodiments, a retaining ring 9 is provided to facilitate the hinge of the telescopic rod 6, and a nut 7 is installed inside the retaining ring 9, so that the telescopic rod 6 is hinged to the retaining ring 9.

[0024] In some embodiments, to enable the device to grip heavier bricks, two sets of telescopic rods 4 and 6 are symmetrically arranged, each set including two telescopic rods 4 and 6. The two sets of telescopic rods 4 and 6 can respectively grip both sides of the larger brick, thereby working together to lift the brick.

[0025] In some embodiments, to improve the linkage between the two sets of telescopic rods 4 and 6, the hinge rod 5 is set as a long rod, and the two sets of telescopic rods 4 and 6 share two hinge rods 5.

[0026] In some embodiments, to improve the stability of the rotating rod 1 when it rotates within the grip 2, a plurality of stabilizing rings 10 are installed inside the grip 2, and the rotating rod 1 is rotatably slidably connected to the stabilizing rings 10.

[0027] In some embodiments, a handle 11 is provided on the rotating rod 1 to facilitate its rotation.

[0028] In some embodiments, to further improve the stability of the grip 2 when the lever 1 rotates, a handle 12 is provided on the grip 2.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
