The safety door is set in the notch on the coal baffle plate 6, and the overpass can be omitted. The safety door can close the passage during production. When production is stopped, the equipment is shut down and locked, and the passage can be opened. The staff can smoothly enter and exit through the safety door, and the corresponding accessories can also be transported, which is convenient and fast. The locking mechanism is used to lock the door body to prevent the safety door from opening at will and causing danger. The warning mechanism 5 judges the door body state of the safety door through the switch sensor and prompts the door body state through the warning light. The staff can observe the warning light to judge whether the safety door can pass.

[0020] The transfer machine safety door according to the embodiment of the utility model has the advantages of safe passage and convenience.

[0021] In some embodiments, the door body includes a door frame 1 and a door panel 2, the door frame 1 is connected to the coal baffle 6, and the door panel 2 is pivotally connected to the door frame 1.

[0022] Specifically, the size of the door frame 1 is larger than that of the door panel 2 , and the door frame 1 can be embedded in the notch on the coal retaining plate 6 . The door panel 2 can be hinged and fixed to the door frame 1 by hinges, so that the door panel 2 can be opened and closed conveniently.

[0023] In some embodiments, a protective member 3 is disposed on the door panel 2 , a first end of the protective member 3 is pivotally connected to the door panel 2 , and a second end of the protective member 3 is detachably connected to the door frame 1 .

[0024] Specifically, after the safety door is opened, the protective member 3 can be connected to the door frame 1 to form a layer of protection on the top of the door panel 2 to protect the staff passing below. The first end of the protective member 3 is rotatably connected to the door panel 2. When the door panel 2 is closed, the second end of the protective member 3 is close to the door panel 2 to retract the protective member 3. When the door panel 2 is opened, the second end of the protective member 3 is fixed to the door frame 1 to form an inclined protection to protect the safety of the staff.

[0025] Optionally, a support rod is provided, and both ends of the support rod are respectively inserted into preset holes on the door panel 2 and the door frame 1. On the one hand, the support rod locks the position of the door panel 2, and on the other hand, the protective member 3 can be laid on the support rod. The protective member 3 can be better protected by supporting it with the help of the support rod.

[0026] In some embodiments, the protective member 3 includes a hook and a protective member, a first end of the protective member is pivotally connected to the door panel 2 , and a second end of the protective member is connected to a hanging ring on the door frame 1 through the hook.

[0027] Specifically, the first end of the protective member can be rotatably connected to the door panel 2 via a rotating shaft, two hooks are arranged on the second end of the protective member, and two hanging rings are arranged on the door frame 1. The hooks and the hanging rings are overlapped to complete the fixation of the protective member. The position of the first end of the protective member should be close to the top of the door panel 2 so as to increase the opening angle of the door panel 2.

[0028] In some embodiments, the protective member includes a plurality of protective plates 31 , and the protective plates 31 are connected to any adjacent protective plates 31 via flexible connectors to allow the protective member to curl and deform.

[0029] Specifically, multiple protective plates 31 are arranged in sequence in the width direction thereof, and the flexible connector can be a buckle, a rope, a chain, etc. The rope connects multiple protective plates 31 in series to form a protective member. Multiple protective plates 31 can play a hard protection role, and the flexible connector enables the protective member to be curled and folded for easy storage.

[0030] In some embodiments, steel plates 4 are provided on both sides of the locking mechanism and the door frame 1 for protection.

[0031] Specifically, the steel plates 4 are clamped and arranged on both sides of the door frame 1 to ensure the reliability of the equipment during operation, enhance the structural strength of the door frame 1, and prevent the door frame 1 from deforming and the safety door from opening and closing failure. The steel plate 4 increases the thickness of the notch of the coal retaining plate 6, which can protect the locking mechanism and the door frame 1. Optionally, the steel plate 4 is 30 mm thick. Selecting a 30 mm thick steel plate 4 can meet the structural strength requirements.

[0032] In some embodiments, the width of the gap is 0.8m, and the width of the door body is adapted to the width of the gap.

[0033] Specifically, the width of the door body is slightly smaller than the width of the notch so that the door frame 1 can be embedded in the notch. When the width of the door body is about 0.8 m, it can meet the needs of personnel passing through and ensure that the structural strength of the coal retaining plate 6 is minimally affected.

[0034] In some embodiments, the locking mechanism includes a door tongue edge and a locking block, the locking block has a limiting hole, the door tongue edge is connected to the door panel 2, the end of the door tongue edge away from the door panel 2 is a wedge-shaped structure, and at least part of the wedge-shaped structure moves relative to the door panel 2 to enter the limiting hole.

[0035] Specifically, the locking block is connected to the coal blocking plate 6, and the opening size of the limiting hole on the locking block is slightly larger than the size of the door tongue edge. The wedge-shaped structure of the door tongue edge can guide itself to slide into the limiting hole, and the wedge-shaped structure can also form a locking force at the closed position to prevent the door panel 2 from being impacted.
