Description

Technical Field

[0001] This disclosure relates to the field of mine ventilation door equipment technology, and in particular to a mechanical ventilation door opening device. Background Technology

[0002] Mine ventilation doors are generally divided into automatic control switches and manual switches. Automatic control doors are expensive and require a lot of maintenance, making it impossible to automate all underground ventilation doors. The pressure difference between the inside and outside of the safety exit pedestrian door in the return air inclined shaft is often maintained at around -1350Pa. It is very difficult for personnel to open the door by hand, and people with less strength generally cannot open it. However, if they are not careful, they may be injured while opening the door, posing a safety hazard. Utility Model Content

[0003] This disclosure is made in view of the above-mentioned problems. This disclosure provides a mechanical damper opening device.

[0004] According to one aspect of this disclosure, a mechanical damper opening device is provided, comprising an auxiliary rod and an opener;

[0005] One end of the auxiliary rod is hinged to the door frame; one end of the opener is fixedly connected to the auxiliary rod; the opener is used to open the door leaf outward when the auxiliary rod rotates about the hinge point with the door frame.

[0006] Furthermore, according to one aspect of this disclosure, a mechanical damper opening device includes a first connecting part, a second connecting part, and a third connecting part. One end of the first connecting part is fixedly connected to the auxiliary rod, and the other end is fixedly connected to one end of the second connecting part. The other end of the second connecting part is fixedly connected to one end of the third connecting part.

[0007] Furthermore, according to one aspect of this disclosure, a mechanical damper opening device comprises a first connecting portion, a second connecting portion, and a third connecting portion forming a Z-shaped structure.

[0008] Furthermore, according to one aspect of this disclosure, in a mechanical damper opening device, the first connecting portion, the second connecting portion, and the third connecting portion are all plate-shaped structures.

[0009] Furthermore, according to one aspect of this disclosure, in a mechanical damper opening device, the first connecting portion, the second connecting portion, and the third connecting portion are all steel plates.

[0010] Furthermore, according to one aspect of this disclosure, in a mechanical damper opening device, when the auxiliary rod is installed on the outside of the door frame, the second connecting portion is clamped between the door frame and the door leaf; the third connecting portion abuts against the inner side of the door leaf.

[0011] Furthermore, according to one aspect of this disclosure, in a mechanical damper opening device, when the auxiliary rod is installed on the inner side of the door frame, the third connecting portion abuts against the inner side of the door leaf.

[0012] Furthermore, according to one aspect of this disclosure, a mechanical damper opening device has a rolling pulley rotatably mounted on one end of the auxiliary rod near the door frame.

[0013] Furthermore, according to one aspect of this disclosure, a mechanical damper opening device has anti-slip textures on the peripheral side of the auxiliary rod at the end away from the door frame.

[0014] Furthermore, according to one aspect of this disclosure, in a mechanical damper opening device, the auxiliary rod is a cylindrical rod.

[0015] This disclosure involves hinged one end of an auxiliary rod to the door frame, fixedly connecting one end of an opener to the auxiliary rod, and placing the other end of the opener against the inside of the door leaf. Lifting or pressing down on the other end of the auxiliary rod causes it to rotate along the hinge point with the door frame, thereby opening the door leaf a certain distance using the principle of a lever that saves effort. This allows a person to open the door leaf a certain distance with one hand. After the door leaf is opened a certain distance, the high-pressure air outside the door leaf enters the door leaf for depressurization. After depressurization, the person can easily open the door leaf, effectively preventing injury from being pinched when opening the door.

[0016] This invention can shorten the time required for personnel to quickly open safety exit doors and escape in the event of a disaster in a mine, ensuring that a single person can easily open the door, which is beneficial to ensuring the safety of workers and improving work efficiency.

[0023] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0024] See Figures 1 to 3 As shown, this disclosure presents a mechanical damper opening device, including an auxiliary rod 1 and an opener 2. One end of the auxiliary rod 1 is hinged to a door frame 3; specifically, one end of the auxiliary rod 1 is rotatably mounted on the door frame 3 via a pin. One end of the opener 2 is fixedly connected to the auxiliary rod 1; in specific implementations, the opener 2 and the auxiliary rod 1 can be fixedly connected by welding. The opener 2 is used to open the door leaf 4 outward when the auxiliary rod 1 rotates around the hinge point with the door frame 3. The cross-section of the auxiliary rod 1 can be circular, quadrilateral, pentagon, or other polygonal shapes. The pressure outside the door leaf 4 is greater than the pressure inside the door leaf 4.

[0025] Furthermore, the opener 2 includes a first connecting part 201, a second connecting part 202, and a third connecting part 203. One end of the first connecting part 201 is fixedly connected to the auxiliary rod 1 by welding, and the other end is fixedly connected to one end of the second connecting part 202 by welding. The other end of the second connecting part 202 is fixedly connected to one end of the third connecting part 203 by welding. In specific implementations, the first connecting part 201, the second connecting part 202, and the third connecting part 203 can also be integrally formed.

[0026] The first connecting part 201, the second connecting part 202, and the third connecting part 203 form a Z-shaped structure. Alternatively, the first connecting part 201, the second connecting part 202, and the third connecting part 203 can also be formed by bending a steel plate or a rigid rod.

[0027] As a preferred approach, the first connecting part 201, the second connecting part 202, and the third connecting part 203 are all plate-shaped structures, such as steel plates.

[0028] When the auxiliary rod 1 is installed on the outside of the door frame 3, the second connecting part 202 is sandwiched between the door frame 3 and the door leaf 4; the third connecting part 203 abuts against the inner side of the door leaf 4. When the auxiliary rod 1 is lifted upwards, as the auxiliary rod 1 rotates around the hinge point with the door frame 3, the third connecting part 203 pulls the door leaf 4 outwards while rotating with the auxiliary rod 1, causing the door leaf 4 to open outwards a certain distance. At this time, the high-pressure air outside the door leaf 4 enters to the other side of the door leaf 4 for depressurization. After depressurization, people can easily open the door leaf, effectively preventing people from being pinched when opening the door. Here, "outwards" refers to the side of the door leaf 4 with higher pressure.

[0029] The second connecting part 202 is designed as a plate structure, making it easier for the second connecting part 202 to be clamped between the door frame 3 and the door leaf 4.

[0030] When the auxiliary rod 1 is installed on the inside of the door frame 3, the third connecting part 203 abuts against the inside of the door leaf 4. When the auxiliary rod 1 is pressed down, the third connecting part 203 rotates with the auxiliary rod 1 and squeezes the door leaf 4 outward to open the door leaf 4. The high-pressure air outside the door leaf 4 enters the inside of the door leaf 4 to release pressure, and after the pressure is released, people can easily open the door leaf.

[0031] Furthermore, a rolling pulley 5 is rotatably installed at the end of the auxiliary rod 1 near the door frame 3, which reduces frictional resistance when the damper is opened.

[0032] To increase the friction between the auxiliary rod 1 and the person's hand, anti-slip textures can be provided on the peripheral side of the auxiliary rod 1 at the end away from the door frame 3.

[0033] To facilitate operation of door leaf 4, door leaf 4 is provided with door handle 6. The setting of door handle 6 is existing technology and can be implemented by those skilled in the art, so it will not be described in detail here.

[0034] In practical use, one of the opening devices disclosed herein can be installed on both the inner and outer sides of the door frame 3. Specifically, for example, one of the opening devices can be installed 1.5 meters high on the outer side of the door frame 3, and another opening device can be installed on the inner side of the outer side of the door frame 3, with the two opening devices offset by a certain distance.

[0035] The opening device disclosed herein utilizes the principle of a force-saving lever, enabling a single person to easily open or close the air door by hand, avoiding injury from being pinched when opening the door, and shortening the time available for personnel to quickly open the safety exit air door and escape in the event of a mine disaster.
