Description

Technical Field

[0001] The invention relates to the technical field of underground space infrastructure design, and in particular to an upward-flipping integrated pipe gallery escape hatch cover device. Background Art

[0002] Urban underground utility corridors are municipal public facilities built underground in cities for laying municipal utility pipelines, which are implemented with unified planning, design, construction and maintenance. Urban underground utility corridors refer to structures and ancillary facilities built underground in cities to accommodate two or more types of engineering pipelines such as water supply, drainage, heat, electricity and communications. The safe and effective operation of municipal pipelines inside underground utility corridors is very important for ensuring the normal operation of cities, and is known as the "lifeline" of modern urban operations.

[0003] All underground utility corridors must be equipped with escape passages so that when a fire or other disaster occurs in the corridor, maintenance personnel in the corridor can quickly escape from the corridor. The existing corridor escape structure is mostly just a simple cover plate, and the escape holes generally have electric opening functions. Although they can be opened and closed electrically, if a disaster occurs, the transmission lines are easily damaged, resulting in failure of electric opening and closing and escape failure, which poses a great risk.

DETAILED DESCRIPTION

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. In the figures, the thickness of regions and layers are exaggerated for clarity. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0022] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention.

[0023] The following example describes an embodiment of the flip-up integrated pipe gallery escape hatch cover device of the present invention. This example is only a part of the embodiments of the present invention, but the protection scope of the present invention is not limited to this. All other embodiments obtained by ordinary technicians in this field without creative work should be included in the protection scope of the present invention.

[0024] Please refer to Figures 1 to 4According to an embodiment of the present invention, a flip-up integrated pipe gallery escape hatch cover device is provided, comprising a cover plate 1 and a cover plate frame 2, wherein the cover plate frame 2 is formed with an escape hatch, the cover plate 1 is hinged to one side of the cover plate frame 2, and has a first position capable of blocking the escape hatch and a second position at a preset opening angle to the horizontal plane, and also comprises an actuating assembly, the actuating assembly being capable of supporting the cover plate 1 so that the cover plate 1 is maintained in the second position, the actuating assembly being capable of applying force to the cover plate 1 in the second position so that the cover plate 1 can switch from the second position to the first position under the action of its own weight, the specific size of the preset opening angle being based on whether a human body can smoothly enter and exit the escape hatch, and in order to ensure that the cover plate 1 will not flip to a side away from the escape hatch due to its own weight, the preset opening angle is generally not greater than 90°, and in a specific implementation, the preset opening angle can be designed to be 90°. In this technical solution, the cover plate 1 can be stably and reliably placed in the second position (i.e., the cover plate is open) through the actuating assembly, an initial downward pressure can be given to the cover plate 1, and the escape opening can be closed (i.e., the first position) under the action of its own weight. The cover plate 1 can be automatically and smoothly opened to ensure that personnel can smoothly enter and exit the escape opening in an emergency. The escape opening cover device fully utilizes the own weight of the cover plate to achieve the blocking of the escape opening, and has a simple structure.

[0025] In some embodiments, the actuating assembly includes a screw 31, a reciprocating seat 32 threadedly connected to the screw 31, and a driving component (such as a driving motor 36) capable of driving the screw 31 to rotate, the reciprocating seat 32 is hinged to the first end of the support arm 33, the second end of the support arm 33 is hinged to the first end of the rocker 34, the cover 1 is hinged to the cover frame 2 through the first rotating shaft 11, the second end of the rocker 34 is rotatably mounted on the first rotating shaft 11, the reciprocating seat 32 can realize its reciprocating linear motion under the action of the thread of the rotating screw 31, and when the cover 1 is in the second position, the rocker 34 is at least partially in supporting contact with the cover 1 toward the first side surface of the cover 1. In this technical solution, the reciprocating seat 32, the support arm 33 and the rocker 34 serve as a linked connecting rod mechanism. When the reciprocating seat 32 moves toward the first direction, it can drive the rocker 34 to move close to the cover plate 1 and form a fold at the hinge point between the rocker 34 and the support arm 33. The folded rocker 34 is pushed to the inner side of the cover plate 1 and finally fits with the inner side of the cover plate 1. At this time, the position of the support arm 33 no longer changes. The support arm 33 is supported between the cover plate 1 and the cover plate frame 2 and maintained in the second position. The thread-driven reciprocating seat 32 effectively prevents the cover plate 1 from closing toward the escape port side under the action of external force due to the effect of the thread self-locking angle, thereby preventing accidents. It should be particularly noted that the first rotating shaft 11 and the rocker 34 in this technical solution are rotatably connected, that is, the opening of the cover plate 1 is only controlled by the supporting effect of the support arm 33 on it, rather than the torque on the first rotating shaft 11. Such a design makes it possible to manually open the cover 1. Specifically, since the actuating assembly is rotatably connected to the first rotating shaft 11 of the cover 1 through the rocker arm 34, whether it is in the first position (that is, when the escape hatch is blocked, that is, when the support arm 33 does not play a supporting role), when a driving component of the actuating assembly fails (for example, the drive motor 36 cannot be started due to lack of power due to long-term non-use), it does not prevent the operator from manually opening or blocking the escape hatch, thereby ensuring the availability of the escape hatch.

[0026] In order to ensure smooth linear motion of the reciprocating seat 32 , the actuating assembly further includes a linear guide rail 35 , and the reciprocating seat 32 is also slidably connected to the linear guide rail 35 .

[0027] like Figure 2 As shown, the position where the first side surface is in contact with the support of the cover plate 1 has a limiting structure. As a specific implementation method, the limiting structure includes a limiting groove 341 constructed on the first side surface and a limiting protrusion 12 constructed on the side of the cover plate 1 facing the rocker 34. When the cover plate 1 is in the second position, the limiting protrusion 12 is in the limiting groove 341. Through the limiting structure, reliable and stable support of the support arm 33 can be guaranteed.

[0028] In some embodiments, the first end of the rocker 34 has a hook 342, and the cover 1 also has a hanging ring 13 on the side facing the rocker 34. The hanging ring 13 is rotatably connected to the cover 1. In this way, the hanging ring 13 can always be in a vertical state under the action of its own weight during the position switching process of the cover 1. For this reason, when the cover 1 is in the second position (specifically opened 90°), the hook 342 can be buckled in the hanging ring 13, and when the cover 1 is in the process of being in the second position to the first position, the hanging ring 13 can move away from the hook 342 to make the hook 342 fall out of the hanging ring 13. In this technical solution, when the cover 1 is in the second position, the hook 342 can be hooked in the hanging ring 13. When the cover 1 needs to be closed, the actuating assembly can be controlled to operate so that the reciprocating seat 32 moves away from the cover 1 (that is, the first rotating shaft 11). The hook 342 of the rocker 34 will apply force to the cover 1 through the hanging ring 13, so that the cover 1 is deflected from the second position toward the first position under the action of its own weight, and the reciprocating seat 32 moves away from the first rotating shaft 11 synchronously. Since the own weight of the hanging ring 13 always maintains a vertical state, it will move away from the hook 342 and finally cause the hook 342 to escape from the hanging ring 13. In this process, the actuating assembly only applies force to the cover 1 at the starting position of the second position and relies on its own weight to block the escape port after the cover 1 is deflected by a certain angle (deviating from the 90° position). The structural design is novel, the actuating assembly does very little work, and reduces the energy consumption of the driving components.

[0029] The hook 342 can be detachably assembled to the first end of the rocker 34. Preferably, the hook 342 and the rocker 34 are integrally formed, which can simplify the assembly process and reduce the occurrence of failures.

[0030] In some embodiments, a torsion spring 4 is mounted on the first rotating shaft 11, and the torsion spring 4 can simultaneously apply force between the cover plate 1 and the cover plate frame 2 so that the cover plate 1 has a tendency to open relative to the cover plate frame 2 when it is in the first position, and has a tendency to close relative to the cover plate frame 2 when it is in the second position. In a specific embodiment, the above function can be realized by a torsion spring with variable stiffness. Specifically, the two force-applying ends of the torsion spring 4 are respectively abutted against the cover plate 1 and the cover plate frame 2. When the cover plate 1 is in the first position, it is subjected to the action of the compression force and thus reacts on the two contact parts so as to have a tendency to open. When the cover plate 1 is in the second position, it is subjected to the action of the tensile force and thus reacts on the two contact parts so as to have a tendency to close. In this state, due to the support of the support arm 33, the cover plate 1 is kept in the second position (for example, vertical) without falling or flipping to the other side. It can be understood that due to the design of the torsion spring 4, it can offset the deadweight of the cover plate 1 to the greatest extent, thereby effectively reducing the force required to manually open the cover plate 1 and effectively reducing the difficulty of manually opening the cover plate 1.

[0031] In some embodiments, a manual locking device 5 is further provided on the side of the cover plate 1 facing the escape hole, so as to lock the cover plate 1 from the inside of the pipe gallery to prevent it from being opened when not needed. The manual locking device 5 specifically includes a rotating hand wheel 51 provided on the cover plate 1 and a corresponding fixed lock buckle 52 provided on the cover plate frame 2. The rotating hand wheel 51 has a rotating lock tongue matched with the fixed lock buckle 52. The rotating lock tongue can be engaged with the fixed lock buckle 52 to form a lock when the rotating hand wheel 51 is rotated in one direction, or released from the fixed lock buckle 52 to form an unlock when the rotating hand wheel 51 is rotated in another direction.

[0032] The cover frame 2 is formed by assembling a plurality of hollow beams, and the actuating components are located in the hollow beams, so that the moving parts are in an independent relatively closed space, preventing possible harm caused by accidental touch by the operator, and making the device structure more compact. A detachable maintenance cover 21 is provided on at least one side wall of the hollow beam facing the escape hole, and the maintenance cover 21 can cover the maintenance window, through which the actuating components located therein can be maintained.

[0033] The following is combined with Figure 1 The working process of the upward-flipping integrated pipe gallery escape hatch cover device of the present invention is further described.

[0034] When the escape hatch needs to be opened electrically, the rotary wheel mechanism (i.e. the aforementioned manual locking device 5) of the cover plate 1 is rotated manually, and the door seat lock tongue (i.e. the aforementioned fixed lock buckle 52) on the escape hatch seat (i.e. the aforementioned cover plate frame 2) rotates to open, and then the motor (i.e. the aforementioned drive motor 36) is started to drive the screw rod 31 to rotate, and the screw rod 31 pulls the push-pull slider seat (i.e. the aforementioned reciprocating seat 32), and the slider seat drives the rocker arm (i.e. the aforementioned rocker 34) to fold and rise upward, driving the hinge mechanism (i.e. the first rotating shaft 11) to rotate and open the cover plate 1 until the cover plate 1 is at a right angle to the escape hatch, and the escape hatch is fully opened.

[0035] When the escape hatch needs to be closed electrically, the motor drives the screw rod 31 to rotate in the opposite direction, and the screw rod 31 pushes the push-pull slider seat. The slider seat drives the rocker arm to fold downward, and the hinge mechanism rotates in the opposite direction to close the cover plate 1 until the cover plate 1 and the escape hatch are completely closed. At this time, the wheel mechanism of the cover plate is rotated manually, and the door seat lock tongue on the escape hatch seat rotates and closes, and the escape hatch is completely closed.

[0036] When the motor fails, manual operation becomes an alternative to electric opening and closing. Although the cover 1 has a large mass, the torsion spring only requires a small amount of manpower to flip up or press down the cover to open and close.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
