Description

Technical Field

[0001] The present application belongs to the technical field of emergency escape passages, and in particular, relates to a locking device for an emergency escape passage. Background Art

[0002] Emergency escape routes refer to routes that can ensure safe evacuation of personnel and smooth access for firefighters to carry out rescue operations in emergency situations, such as fires. These routes are crucial to protecting people's lives and must be strictly set up and maintained. Evacuation routes and emergency exits in production and operation sites must be kept unobstructed to ensure that people can evacuate quickly and safely in an emergency to reduce casualties.

[0003] At present, some emergency escape passages still use locks, and they must be opened temporarily with keys when encountering dangerous situations. For example, some existing production operation platforms are equipped with two emergency escape passages in opposite directions, but they are locked with ordinary open locks. For example, on the gas production operation platform, every time gas operation and maintenance are carried out, a special person must be arranged to manually open the escape protection door of the steel inclined ladder. First, if this operation step is forgotten, once a sudden gas leakage accident occurs, it may cause a serious production safety accident; second, it increases the operation steps for gas operators; and third, it wastes human resources. Summary of the invention

[0004] The present application aims to at least to some extent solve the technical problem that the emergency passage door is inconvenient to open. To this end, the present application provides an emergency escape passage locking device that can quickly open the emergency passage to ensure smooth flow, thereby reducing the occurrence of safety accidents and ensuring personnel safety.

[0005] The embodiment of the present application provides an emergency escape passage locking device, which includes:

[0006] Gravity ring, used to be installed next to the locked door of the emergency escape passage;

[0007] A slider, used for connecting the lock door, the slider is provided with a notch;

[0008] The slider can slide between a first position and a second position, the gravity ring is movable relative to the lock door and can be inserted into or disengaged from the slot, when the slider is in the first position, the gravity ring is inserted into the slot, and when the slider is in the second position, the slider is separated from the gravity ring, allowing the lock door to open.

[0009] In some embodiments, the first position is higher than the second position, and the first position and the second position are on an inclined line.

[0010] In some embodiments, a slide rail is further included, and the slide rail is used to be fixed on the lock door, and the slide rail is slidably matched with the slider.

[0011] In some embodiments, the slider is tilted so that the first position is located at an end of the slider away from the locking door, and the second position is located at an end close to the locking door.

[0012] In some embodiments, the range of motion of the gravity ring satisfies: the distance between the gravity ring and the slide rail ∈[a, b], where a is less than the distance d that the slider protrudes from the slide rail, and b is greater than the distance d that the slider protrudes from the slide rail.

[0013] In some embodiments, a positioning rod is further included, which is used to be fixed next to the lock door of the emergency escape passage and to hang a gravity ring. When the gravity ring is hung on the positioning rod, the gravity ring can clamp the slider.

[0014] In some embodiments, a pull wire is further included, one end of which is connected to the gravity ring, and the other end of the pull wire is used to extend to an emergency escape passage spaced apart from the locked door.

[0015] In some embodiments, a protective cover is further included, and the protective cover shields the gravity ring and the sliding block by a covering manner.

[0016] In some embodiments, a pull ring is further included, wherein the pull ring is connected to the end of the pull wire and is used to pull the pull wire.

[0017] In some embodiments, a pipe fitting is further included, and the pipe fitting is used to be fixed in the emergency escape passage. The pipe fitting is sleeved on the pull wire, and the inner diameter of the pipe fitting is smaller than the outer diameter of the pull ring.

[0018] It can be seen from the above technical solution that the beneficial effects of this application are:

[0019] The present application sets a gravity ring, which can activate the gravity ring to open the passage between the first position and the second position when encountering danger, so that the slider can slide from the first position to the second position after the gravity ring is activated. When the slider is in the first position, the gravity ring clamps the slider, and then the locking door can close the emergency escape passage. When the slider is in the second position, it is no longer clamped by the gravity ring, and the locking door can open the emergency escape passage. In this way, the emergency passage can be opened quickly to ensure smooth flow, thereby reducing the occurrence of safety accidents and ensuring the safety of personnel.

[0029] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Please refer to Figure 1 and Figure 2 , the embodiment of the present application provides an emergency escape passage lock device, which is installed in the emergency escape passage 20 of industrial production, such as installed at the personnel escape steel fence door of the two-way ladder of the gas operation platform. The two-way ladder adopts a steel ladder and is set at an angle. Taking the emergency escape passage 20 as an example, the device includes a gravity ring 11 and a slider 12. The gravity ring 11 is ring-shaped. The gravity ring 11 is used to be set next to the lock door 30 of the emergency escape passage 20. The gravity ring 11 adopts an iron ring. The gravity ring 11 is movably connected to the steel ladder, such as the gravity ring 11 is hung on the transverse beam of the steel ladder, so that the gravity ring 11 has a larger activity space; the slider 12 is used to connect the lock door 30, such as one end of the slider 12 is welded and fixed to the lock door 30, and the other end of the slider 12 extends toward the steel ladder. A notch 123 is set on the slider 12, and the notch 123 passes through the slider 12. The gravity ring 11 When the slider 12 is connected to the lock door 30, the lock door 30 is locked by the gravity ring 11; the slider 12 can slide between the first position 121 and the second position 122. For example, the top of the slide rail 13 is the first position 121 and the bottom is the second position 122. At the first position 121, the gravity ring 11 can be adjusted to clamp the slider 12, so as to complete the connection between the gravity ring 11 and the slider 12, that is, the lock door 30 is closed. In order to increase stability, a groove can be provided at the bottom of the slider 12, and the gravity ring 11 is clamped in the groove and fixed. When the lock door 30 needs to be opened, the gravity ring 11 is adjusted to make the gravity ring 11 move and disengage from the slider 12. The slider 12 falls to the bottom under the action of gravity, and the lock door 30 is opened.

[0031] In some embodiments, the gravity ring 11 and the slide rail 13 can also be matched in other ways, such as providing a slide rail 13 or a slide groove on the lock door 30, and the slider 12 slides and matches with the slide rail 13 or the slide groove. Taking the slide groove as an example, the slider 12 can be placed in the slide groove and move relative to the slider 12. The first position 121 is located at one end of the slide rail 13, and the second position 122 is located at the other end of the slide rail 13. When in the first position 121, the gravity ring 11 is inserted into the groove 123 provided on the slider 12 and is in a locked state. After the gravity ring 11 moves, it disengages from the slider 12, and the slider 12 can slide to the second position 122 to unlock. The slide groove is set in the horizontal direction or the vertical direction. In order to quickly open the lock door 30, the slide groove can be set to the vertical direction. The gravity ring 11 is movable relative to the lock door 30 and can be inserted into or separated from the notch 123. When the slider 12 is in the first position 121, the gravity ring 11 is inserted into the notch 123. When the slider 12 is in the second position 122, the slider 12 is separated from the gravity ring 11, so that the lock door 30 is opened. In this way, it can prevent people outside the lock door 30 from opening, and the gravity ring 11 can be moved to quickly open the lock door 30 when escaping. The slider 12 can be closely matched with the gravity ring 11. In the first position 121, the gravity ring 11 clamps the slider 12 to close the lock door 30. In the second position 122, the gravity ring 11 separates from the slider 12 to open the lock door 30, effectively ensuring the locking and rapid opening between the slider 12 and the gravity ring 11 without delay, ensuring the effective unblocking of the emergency escape passage 20, and optimizing the ease of operation of the passage, which is suitable for emergency use.

[0032] The emergency passage door of the prior art is inconvenient to open because the emergency passage door adopts a lock. When in danger, you must hold a key to open it. In case of danger, it may cause serious production safety accidents. However, the present application sets a gravity ring 11, which can move the gravity ring 11 to open the passage between the first position 121 and the second position 122 when in danger. In this way, the slider 12 can slide from the first position 121 to the second position 122 after the gravity ring 11 is moved. When the slider 12 is in the first position 121, the gravity ring 11 clamps the slider 12, and then the lock door 30 can close the emergency escape passage 20. When the slider 12 is in the second position 122, it is no longer clamped by the gravity ring 11, and the lock door 30 can open the emergency escape passage 20. In this way, the emergency passage can be opened quickly to ensure smooth flow, thereby reducing the occurrence of safety accidents and ensuring the safety of personnel; at the same time, the lock of the lock door 30 is omitted, which can reduce the configuration cost of the emergency escape passage 20.

[0033] Please refer to Figure 3In some embodiments, the height of the first position 121 is higher than the second position 122, and the first position 121 and the second position 122 are on an inclined line. For example, the top and bottom ends of the slide groove are respectively used as the first position 121 and the second position 122. The first position 121 is higher than the second position 122 so that when the slider 12 is separated from the gravity block, that is, when the gravity block no longer clamps the slider 12, the slider 12 can slide downward under the action of gravity, and the slider 12 has less friction when sliding. In some embodiments, the device also includes a slide rail 13, which is used to be fixed to the lock door 30. The slide rail 13 is slidably matched with the slider 12. The slide rail 13 is a conventional device. One end of the slide rail 13 is fixed to the inner side of the lock door 30, such as by welding or screw fixing. The other end of the slide rail 13 extends in the direction of the gravity ring 11, so that when the lock door 30 is closed, the first position 121 of the slide rail 13 can reach the range of motion of the gravity ring 11.

[0034] In some embodiments, the slider 12 is tilted so that the first position 121 is located at the end of the slider 12 away from the lock door 30, and the second position 122 is located at the end close to the lock door 30. The tilt angle is designed according to needs. For example, when the friction between the slide rail 13 and the slider 12 is small, the tilt angle may be between 15° and 30°. When the friction is large, the tilt angle may be greater than 45° or 60°. The second position 122 is the bottom end of the slide rail 13, adjacent to the lock door 30, and the first position 121 is the top end of the slide rail 13, close to the gravity ring 11. In some embodiments, the range of motion of the gravity ring 11 satisfies: the spacing between the gravity ring 11 and the slide rail 13 ∈ [a, b], wherein a is less than the distance d that the slider 12 protrudes from the slide rail 13, and b is greater than the distance d that the slider 12 protrudes from the slide rail 13. When the slide rail 13 is tilted, the spacing between the gravity ring 11 and the slide rail 13 and the distance that the slider 12 protrudes from the slide rail 13 are parameters perpendicular to the oblique direction of the slide rail 13 in the tilted state. The spacing between the gravity ring 11 and the slide rail 13 is the shortest distance between the outer edge of the gravity ring 11 and the slide rail 13, and the distance that the slider 12 protrudes from the slide rail 13 is the distance between the top surface of the slider 12 and the top surface of the slide rail 13. The above a, b, and d are all length parameters greater than 0, so that the gravity ring 11 can both clamp the slider 12 in the first position 121 and separate from the slider 12 after being lifted, allowing the slider 12 to slide from the first position 121 to the second position 122.

[0035] Clear reference Figure 3In some embodiments, the device further includes a positioning rod 14, which may be a rod made of steel. The positioning rod 14 is used to be fixed next to the lock door 30 of the emergency escape passage 20 and to hang the gravity ring 11. For example, the positioning rod 14 is welded to the steel ladder and arranged horizontally. When the gravity ring 11 is hung on the positioning rod 14, the gravity ring 11 can clamp the slider 12 at the first position 121, that is, the gravity ring 11 clamps the slider 12 in the natural state of the gravity ring 11 being suspended; after the positioning rod 14 is set, the inner side of the gravity ring 11 leans against the positioning rod 14, and the gravity ring 11 can move freely under the constraint of the positioning rod 14 on the inside, such as the inner edge of the gravity ring 11 can always stick to the positioning rod 14 to make a circular movement, so that when the lock door 30 needs to be locked, the lock door 30 is pushed, and the slider 12 moves to the first position 121 and is clamped with the gravity ring 11, and the lock door 30 can be closed. In order to facilitate the installation of the positioning rod 14, a mounting plate 15 is also provided. The mounting plate 15 is fixed to the end of the steel ladder close to the locking door 30. For example, the mounting plate 15 is welded to the end of the steel ladder and is located in the middle of the steel ladder column. The positioning rod 14 is welded to the mounting plate 15. The mounting plate 15 can effectively prevent the locking door 30 from failing due to structural deformation.

[0036] Please refer to Figure 2 In some embodiments, the device further includes a pull wire 16, which is made of a steel wire rope, a rope or other tough wire. One end of the pull wire 16 is connected to the gravity ring 11, and the pull wire 16 is tied and fixed to the gravity ring 11. The other end of the pull wire 16 is used to extend to the emergency escape passage 20 separated from the locked door 30. For example, this end of the pull wire 16 extends to the middle position of the handrail of the steel ladder. In this way, when people pass through the emergency passage, they can operate the pull wire 16 on the handrail to pull the gravity ring 11, thereby separating the slider 12 from the gravity ring 11. In some embodiments, the device further includes a protective cover 19, which shields the gravity ring 11 and the slider 12 by a covering manner. The protective cover 19 may be in a box-like, spherical or other shapes. The protective cover 19 is a shell that can surround or enclose the gravity ring 11 and the slider 12. After the protective cover 19 is used, the gravity ring 11 and the slider 12 are both in the protective cover 19, wherein the pull wire 16 passes through the protective cover 19 without affecting the operation of the pull wire 16, thereby ensuring that the gravity ring 11 and the slider 12 work normally and are not affected by mechanical damage or operational use; at the same time, the locking device is not affected by rainy and snowy weather, reduces corrosion caused by weather changes, and reduces damage and replacement frequency.

[0037] Please refer to Figure 2In some embodiments, the device further includes a pull ring 17, which is connected to the end of the pull wire 16. The pull ring 17 is annular, and the pull ring 17 is tied and fixed to the pull wire 16. The pull ring 17 is used to pull the pull wire 16 to open the lock door 30. The pull ring 17 is convenient for personnel to hold and operate. In this way, one end of the pull wire 16 is connected to the gravity ring 11, and the other end is connected to the pull ring 17. When the lock door 30 needs to be opened, the gravity ring 11 can be pulled to move by pulling the pull ring 17, that is, the gravity ring 11 can be pulled to a state of separation from the slider 12. After separation, the slider 12 is no longer constrained by the gravity ring 11, and then the lock door 30 is opened; the pull ring 17 is located on the handrail of the steel ladder, specifically located at the handrail 2m away from the lock door 30, so that when the escapee passes through the emergency escape passage 20, it is convenient to use, and the lock door 30 can be opened by directly pulling the pull ring 17. In some embodiments, the device also includes a pipe fitting 18. The pipe fitting 18 is made of a steel pipe, and can also be made of a PVC pipe or other pipe. The pipe fitting 18 is used to be fixed in the emergency escape passage 20. The pipe fitting 18 is arranged along the emergency escape passage 20, such as welding the pipe fitting 18 to the inner side of the handrail of the steel ladder, or fixing it with screws. The pipe fitting 18 is provided with a channel, and the pull wire 16 passes through the channel, so that the pipe fitting 18 is sleeved on the pull wire 16, and the inner diameter of the pipe fitting 18 is smaller than the outer diameter of the pull ring 17, which is convenient for holding; the pipe fitting 18 protects the pull wire 16, which will not affect the handrail function.
