Each time, it is necessary to remove four inlet locking screws, and it is difficult to close after opening. After multiple operations, high-temperature coal slag leakage has occurred, resulting in personal injury or boiler shutdown. Therefore, it is necessary to study a safe, reliable and easy-to-operate safety lock for the slag cooler manhole. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a safety lock for the inlet door of a slag cooler, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety lock for the inlet door of a slag cooler, comprising a slag cooler body, an inlet door body of the slag cooler body installed at the inlet of the slag cooler body, a movable pull rod fixedly installed on one side of the outer wall of the inlet door body, a movable plate slidably connected to the side wall of the slag cooler body at the inlet, a limit plate and an insertion plate welded to the bottom of the movable plate respectively, and a movable latch hinged to the front side of the movable plate.

[0005] As a preferred technical solution of this utility model, the main body of the slag cooler is provided with two sets of sliding grooves on one side of the inlet, and a slider is placed in the sliding groove. The outer wall of the slider is fixedly connected to the two sides of the moving plate near the main body of the slag cooler, and the cross-section of the sliding groove is T-shaped.

[0006] As a preferred technical solution of this utility model, the movable tie rod has a groove on the side near the body of the slag cooler.

[0007] As a preferred embodiment of this utility model, the gap between the limiting plate and the insertion plate welded to the bottom of the movable plate can accommodate the movable pull rod, and the insertion plate can be inserted into the groove opened by the movable pull rod.

[0008] As a preferred technical solution of this utility model, the movable plate is made of a steel plate with a thickness of 14mm, a length of 150mm, and a width of 80mm.

[0009] As a preferred embodiment of this utility model, a connecting plate is welded to the top of the movable plate, and a lifting plate is welded to one side of the connecting plate.

[0010] As a preferred embodiment of this utility model, the side of the insertion plate closest to the limiting plate is inclined, and the bottom side of the movable locking pin is also inclined.

[0011] Compared with the prior art, this utility model provides a safety lock for the inlet door of a cold slag machine, which has the following advantages:

[0012] 1. This safety lock for the inlet door of a cold slag machine, by setting a movable locking pin, a limiting plate, a moving plate and an insertion plate, can push the lifting plate, and can drive the moving plate to move through the connecting plate, so that the insertion plate can be inserted into the groove opened in the movable pull rod, and the limiting plate is located on the outer surface of the movable pull rod. When the moving plate moves, the movable locking pin can be locked on the movable pull rod, which can limit the moving plate, thereby locking the inlet door of the cold slag machine to the cold slag machine body, which is convenient to operate;

[0013] 2. This type of safety lock for the inlet door of a cold slag machine, by setting up a lifting plate, a connecting plate, a moving plate, a limiting plate, and an insertion plate, allows the movable locking pin to be pulled outward, causing it to disengage from the movable pull rod. Then, the lifting plate can be pushed upward, which in turn moves the moving plate upward through the connecting plate, thereby disengaging the limiting plate and the insertion plate from the movable pull rod. At this point, the inlet door of the cold slag machine can be opened by the movable pull rod, making the operation relatively convenient. Attached Figure Description

[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] Please see Figure 1-Figure 3In this embodiment: a safety lock for the inlet door of a slag cooler includes a slag cooler body 1, an inlet door body 2 installed at the inlet of the slag cooler body 1, a movable pull rod 3 fixedly installed on one side of the outer wall of the inlet door body 2, the inlet door body 2 can be opened or closed by the movable pull rod 3, a movable plate 6 is slidably connected to the side wall of the slag cooler body 1 at the inlet, the movable plate 6 can move on the side wall of the slag cooler body 1 at the inlet, a limit plate 5 and an insertion plate 8 are welded to the bottom of the movable plate 6 respectively, which can limit the movable pull rod 3, and a movable locking pin 4 is hinged to the front side of the movable plate 6 to limit the movable plate 6.

[0020] In this embodiment, the slag cooler body 1 has two sets of sliding grooves on one side at the inlet, and a slider is placed in the sliding groove. The outer wall of the slider is fixedly connected to both sides of the movable plate 6 near the slag cooler body 1. The cross-section of the sliding groove is T-shaped to facilitate the movement of the movable plate 6. The movable pull rod 3 has a groove on the side near the slag cooler body 1, and the insertion plate 8 can be inserted into the groove. The gap between the limiting plate 5 welded to the bottom of the movable plate 6 and the insertion plate 8 can accommodate the movable pull rod 3, which can limit the movement of the movable pull rod 3. The insertion plate 8 can... The movable plate 6 is made of steel plate with a thickness of 14mm, a length of 150mm, and a width of 80mm. A connecting plate 7 is welded to the top of the movable plate 6, and a lifting plate 9 is welded to one side of the connecting plate 7. Pushing the lifting plate 9 can move the connecting plate 7. The side of the insertion plate 8 near the limiting plate 5 is set at an angle, so that it can be easily inserted into the groove of the movable pull rod 3. The bottom side of the movable locking pin 4 is also set at an angle, so that it can be easily locked on the movable pull rod 3 when the movable locking pin 4 moves downward.
