Description

Technical Field

[0001] This invention relates to an auxiliary system and method for installing air-raid shelter doors, and more particularly to an installation system and method for double-leaf air-raid shelter doors. Background Technology

[0002] As a core protective device in civil air defense projects, air defense doors are mainly used to block harmful substances such as shock waves and toxic agents from passing through the project openings. Their installation quality directly determines the protective effectiveness and safety reliability of the civil defense project, and they are widely used in various civil defense projects such as underground buildings, civil defense fortifications, and tunnel entrances. Among them, double-leaf air defense doors, with their advantages of flexible opening, high passage efficiency, and adaptability to large-span openings, are widely used in the entrances and exits of large-sized civil defense projects. However, their special structure, consisting of two independent door leaves, results in a large overall span and a heavy weight for each door leaf, causing many inconveniences in installation and construction.

[0003] Currently, during the installation of air-raid shelter doors, due to limitations in construction site conditions and insufficient versatility of installation equipment, most construction units still use the traditional method of manual labor combined with electric hoists for suspension. While this method can achieve the hoisting and positioning of the door panels to a certain extent, it has many shortcomings that urgently need to be addressed in practical applications, making it difficult to meet the requirements for efficient, safe, and precise installation of double-leaf air-raid shelter doors. The specific shortcomings are as follows:

[0004] First, the installation of electric hoists requires finding or installing additional lifting points, resulting in a large workload for construction preparation. Civil defense engineering construction sites are often unfinished underground spaces or fortifications, with complex environments and a lack of pre-designed dedicated lifting points. Before installation, construction workers must spend a significant amount of time inspecting the site's load-bearing structure and finding temporary lifting points that meet the load-bearing requirements, such as steel beams or load-bearing columns. If there are no suitable natural lifting points on site, temporary simple lifting points must be installed. The installation of temporary lifting points not only increases construction procedures and labor costs but also requires repeated testing of the lifting points' load-bearing capacity to ensure they meet the weight requirements for hoisting the civil defense doors, further extending the construction preparation period and affecting the construction progress.

[0005] Secondly, the stability and safety of electric hoists during suspension installation are relatively poor. Electric hoists primarily rely on single or simple combinations of slings to connect the door panels, and their core design is vertical lifting. However, during the installation of air-raid shelter doors, the door panel's posture often needs to be adjusted, which can easily generate lateral traction. This causes the door panel to sway and shift during suspension, making it difficult to accurately control the door panel's spatial position. This not only affects installation accuracy, resulting in a loose fit between the door panel and the door frame, compromising the airtightness of the air-raid shelter door, but also risks accidents caused by the door panel swaying and colliding with equipment, walls, or construction workers at the construction site.

[0006] Finally, for double-leaf air-raid shelter doors, their large span and heavy individual leaf weight necessitate multiple lifting points for electric hoist installation, resulting in low construction efficiency. The span of a double-leaf air-raid shelter door is typically much larger than that of a standard single-leaf door. A single lifting point cannot meet the load-bearing and balance requirements of the door leaf. Construction workers must set up multiple lifting points at different locations on the door leaf, using multiple electric hoists working in tandem for suspension installation. However, the precise positioning and installation of multiple lifting points requires precise control of spacing and force balance, making operation difficult. Furthermore, the synchronous control of multiple electric hoists is challenging, easily leading to uneven force distribution at the lifting points and door leaf tilting. This necessitates repeated adjustments to the lifting point positions and door leaf posture during installation, significantly increasing construction procedures and operation time, and markedly reducing construction efficiency. In addition, the multiple lifting points further increase the workload of finding and installing them, exacerbating the problem of low construction efficiency.

[0007] In summary, the existing installation methods for air-raid shelter doors mainly rely on electric hoists for suspension, which has many drawbacks such as cumbersome hoisting point settings, poor stability and safety, and low installation efficiency. These methods are no longer suitable for the efficient and safe installation requirements of double-leaf air-raid shelter doors. Therefore, developing an installation system for double-leaf air-raid shelter doors that can solve the above-mentioned shortcomings of existing technologies has important practical significance and application value.

[0035] The lifting support mechanism, rotating support mechanism, and cantilever support mechanism enable spatial position adjustment of the double-end suspension mechanism, providing a wide range of hoisting space for the installation of the air-raid shelter door 100. This eliminates the need for manual intervention to damage the wall installation points, and the hoisting and installation of the air-raid shelter door 100 can be completed with minimal manpower through the drive control of the control cabinet 5. The double-end suspension mechanism and tilt adjustment mechanism allow for precise adjustment based on the installation docking angle of the air-raid shelter door 100, ensuring efficient installation. The movable support mechanism facilitates system movement and transportation. The door frame positioning mechanism locks the system relative to the door frame 102, ensuring the stability of the system support.

[0036] like Figure 1-3 As shown, the movable support mechanism includes a longitudinal support beam 1, two transverse support beams 2, and four casters 3. The two transverse support beams 2 are respectively fixed laterally to the middle of the left and right sides of the longitudinal support beam 1. The four casters 3 are respectively installed below the front and rear ends of the longitudinal support beam 1 and below the cantilevered ends of the two transverse support beams 2. A door frame positioning mechanism is connected to the rear end of the longitudinal support beam 1, and a lifting support mechanism is fixed to the middle of the upper side of the longitudinal support beam 1. The four casters 3 support the cross-shaped support frame formed by the longitudinal support beam 1 and the two transverse support beams 2, thereby facilitating the movable support mechanism to achieve movable support.

[0038] like Figure 1-3 As shown, multiple pin holes are provided on the hinge seat 7, and a swing positioning hole is provided on the auxiliary support rod 8. A positioning pin 9 is inserted into each hinge seat 7, and the positioning pin 9 passes through a pin hole and is inserted into the swing positioning hole, thereby realizing the swing limit of the auxiliary support rod 8.

[0039] like Figure 1-3As shown, the door frame positioning mechanism includes a folding connecting rod 51, a bottom clamping unit, and a telescopic support unit. One end of the folding connecting rod 51 is fixedly connected to the bottom clamping unit, and the other end is pivotally hinged to the rear end of the longitudinal support beam 1. The bottom clamping unit is used to clamp onto the lower side frame of the door frame 102. The lower end of the telescopic support unit is pivotally hinged to the bottom clamping unit, and the upper end is supported on the upper side frame of the door frame 102. When folded, the upper end of the telescopic support unit is in a snap-fit ​​state. The bottom clamping unit can be clamped onto the lower side frame of the door frame 102, thereby connecting the movable support mechanism to the door frame 102 via the folding connecting rod 51, enhancing the support stability of the movable support mechanism. At the same time, it cooperates with the upper horizontal support unit to provide stable support for the lifting support column 15, ensuring the stability of the air defense door 100 during hoisting. The telescopic support unit can enhance the installation reliability of the bottom clamping unit and prevent displacement and shaking of the bottom clamping unit during the hoisting of the air defense door 100.

[0040] like Figure 1-3 As shown, the bottom clamping unit includes a bottom support plate 50 and multiple clamping bolts 53. The bottom support plate 50 is horizontally supported on the lower side frame of the door frame 102, and multiple clamping seats 65 are spaced apart on the front and rear sides of the bottom support plate 50. Each clamping bolt 53 is longitudinally threaded and screwed onto each clamping seat 65, and a clamping disc 55 is rotatably installed on the clamping end of each clamping bolt 53. Each clamping disc 55 is used to support the front and rear sides of the lower side frame of the door frame 102, so that it can be rotated and adjusted when the clamping bolt 53 is pressed. A clamping handle 54 is provided on the other end of each clamping bolt 53, so as to facilitate manual and quick rotation of the clamping bolt 53.

[0041] like Figure 1-3As shown, the telescopic support unit includes a telescopic support tube 59, a telescopic support stud 61, and a threaded drive seat 62. The lower end of the telescopic support tube 59 is pivotally hinged to the center of the upper side of the bottom support plate 50 via a support hinge seat 64. The threaded drive seat 62 is rotatably mounted at the upper end of the telescopic support tube 59, and a rotary adjustment handle 63 is provided on the threaded drive seat 62 for easy manual rotation. The lower end of the telescopic support stud 61 is threadedly screwed onto the threaded drive seat 62, and a top support disc 60 is fixedly mounted on the upper end, thereby achieving stable support for the upper end of the telescopic support stud 61 and preventing the telescopic support stud 61 from rotating along with the threaded drive seat 62. A folding limit seat 66 is provided on the longitudinal support beam 1, and a limit slot 67 for partially inserting and limiting the top support disc 60 is inclinedly provided on the folding limit seat 66, thereby limiting the top support disc 60 during folding and transportation and ensuring stability during transportation.

The horizontal support screw 21 is threaded through and screwed onto the support adjustment threaded hole. The roller support seat 22 is fixedly installed on the outer end of the horizontal support screw 21. Each wall support roller 23 is rotatably installed on the two vertical sides of the roller support seat 22, thus providing rolling support on the vertical wall 101.

[0047] like Figure 1-3As shown, the rotating support mechanism includes a rotating support sleeve 16 and a rotating drive motor 17. The rotating support sleeve 16 is rotatably mounted on the lifting support column 15. The rotating drive motor 17 is fixedly mounted on the upper side of the lifting support column 15 via an upper motor support 56, and drives the rotating support sleeve 16 to rotate via a top worm gear transmission unit. The cantilever support mechanism and the tilt adjustment mechanism are both mounted on the rotating support sleeve 16, thereby achieving synchronous rotation of the cantilever support mechanism and the tilt adjustment mechanism. The rotating drive motor 17 is driven and controlled by the control cabinet 5.

[0048] like Figure 1-3 As shown, a support ring 58 is provided on the lifting support column 15, and the lower end of the rotating support sleeve 16 is rotatably supported on the support ring 58, thereby ensuring the vertical support stability of the lifting support column 15 on the rotating support sleeve 16.

[0049] like Figure 1-3 As shown, the top worm gear transmission unit includes a rotary drive worm wheel 18 and a rotary drive worm 19.

The U-shaped movable seat 29 is slidably mounted on the cantilever beam 24, and a translation drive seat 27 is provided on the top of the U-shaped movable seat 29, with the translation drive screw 26 threadedly screwed onto the translation drive seat 27. A double-end suspension mechanism is mounted on the U-shaped movable seat 29. The translation drive motor 28 is driven and controlled by the control cabinet 5. The U-shaped movable seat 29 is fastened to the cantilever beam 24 and moves along the cantilever beam 24, thereby ensuring the stability of the U-shaped movable seat 29.

[0051] like Figure 1 , 2As shown in Figure 4, a roller support groove 25 is provided along the length direction on the vertical side of the cantilever beam 24, and multiple support rollers 30 are provided on both vertical side plates of the U-shaped moving seat 29. Each support roller 30 supports the movement within the roller support groove 25 on the corresponding side, thereby ensuring the stability of the movement of the U-shaped moving seat 29 and reducing the movement resistance.

[0052] like Figure 1 , 2 As shown in Figure 4, the double-end suspension mechanism includes two lifting drive motors 33, two steel rope winding and unwinding units, two steel wire ropes 35, and two hooks 36. The two steel rope winding and unwinding units and the two lifting drive motors 33 are all mounted on the U-shaped movable seat 29, and the two lifting drive motors 33 drive the two steel rope winding and unwinding units respectively. One end of each of the two steel wire ropes 35 is connected to one of the two steel rope winding and unwinding units, and the other end is connected to one of the two hooks 36 respectively. The two lifting drive motors 33 are driven and controlled by the control cabinet 5. By using the two lifting drive motors 33 to drive the two steel rope winding and unwinding units respectively, the two hooks 36 can be suspended at different heights. During the hoisting process of the air-raid shelter door 100, the tilt angle of the air-raid shelter door 100 can be adjusted as needed.

[0053] like Figure 1 , 2 As shown in Figure 4, the steel rope winding and unwinding unit includes a winding and unwinding winch 31, a winding and unwinding drive worm gear 32, and a winding and unwinding drive worm 37. The winding and unwinding winches 31 of the two steel rope winding and unwinding units are rotatably mounted between the two vertical side plates of the U-shaped moving base 29 via winch shafts 34, and are located at the lower part of the U-shaped moving base 29. The winding and unwinding drive worm gears 32 of the two steel rope winding and unwinding units are respectively fixedly mounted on the two winch shafts 34 and rotate synchronously with the winding and unwinding winches 31. The two winding and unwinding drive worm gears 37 are rotatably mounted on the U-shaped moving base 29, and the two winding and unwinding drive worm gears 37 are respectively meshed with the two winding and unwinding drive worm gears 32. The output shafts of the two lifting drive motors 33 are respectively connected to the ends of the two winding and unwinding drive worm gears 37. The upper ends of the two steel wire ropes 35 are respectively wound and fixed on the two winding and unwinding winches 31. By utilizing the cooperation between the worm gear 32 and the worm 37, the rotation drive of the winch 31 can be realized, and the rotation limit of the winch 31 can be set after the rotation stops, so as to ensure the stability of the hoisting of the air defense door 100.

[0054] like Figure 1-3As shown in Figure 5, the tilt adjustment mechanism includes an adjustment drive motor 42, an adjustment support shaft 45, a rotating support sleeve 46, a tilting support shaft 47, and two adjustment push rods 48. One end of the adjustment support shaft 45 is vertically fixed to the lower end of the rotating support sleeve 16, and the rotating support sleeve 46 is rotatably mounted on the other end of the adjustment support shaft 45. The adjustment drive motor 42 is fixedly mounted on the adjustment support shaft 45 via a lower motor support 41, and drives the rotating support sleeve 46 to rotate via an adjustment worm gear unit. The tilting support shaft 47 is rotatably mounted through the middle of the rotating support sleeve 46, and the tilting support shaft 47... The rotation involves a certain amount of rotational friction to prevent the two adjusting push rods 48 from tipping over freely. The two adjusting push rods 48 are vertically fixed at both ends of the flip support shaft 47, and are parallel to each other. The distance between the two adjusting push rods 48 is greater than the thickness of the air-raid shelter door 100. A rotation limit block 50 is provided on the flip support shaft 47, and a limit stop block 71 is provided on the rotation support sleeve 46 to block the rotation limit block 50. When the limit stop block 71 blocks the rotation limit block 50, the two adjusting push rods 48 are in a longitudinal horizontal state. The adjusting drive motor 42 is driven and controlled by the control cabinet 5. The rotating support shaft 47 allows the two adjusting push rods 48 to be switched between vertical and horizontal states. Therefore, after the air-raid shelter door 100 is lifted, the two adjusting push rods 48 can be swung from a vertical position to a horizontal position, or after the air-raid shelter door 100 is installed, the two adjusting push rods 48 can be swung from a horizontal position to a vertical position, thus not affecting the lifting and releasing of the air-raid shelter door 100. The adjusting drive motor 42 drives the rotating support sleeve 46 to rotate via the adjusting worm gear unit, thereby bringing the two adjusting push rods 48 close to the side of the air-raid shelter door 100 after rotation. The two adjusting push rods 48 are adjusted to different heights. The push rod 48 clamps and pushes the air defense door 100 to adjust its tilt angle. If it needs to tilt to the other side, the rotating support sleeve 46 is driven in the opposite direction to switch the pushing direction of the two adjusting push rods 48. The rotating limit block 50 and the limit stop block 71 can be used to limit the rotation of the flip support shaft 47, preventing the two adjusting push rods 48 from swinging downwards and failing to clamp onto the air defense door 100. The two adjusting push rods 48 can also limit the air defense door 100 during large-scale horizontal transfer to prevent it from shaking too much and ensure the safety of hoisting.

[0055] like Figure 1-3As shown in Figure 5, the adjusting worm gear unit includes an adjusting drive worm gear 44 and an adjusting drive worm 43. The adjusting drive worm gear 44 is mounted on the rotating support sleeve 46, and the adjusting drive worm 43 is rotatably mounted on the lower motor support 41, with the adjusting drive worm gear 44 and adjusting drive worm 43 meshing together. The output shaft of the adjusting drive motor 42 is connected to the end of the adjusting drive worm 43. Wear-resistant sleeves 49 are fitted on both adjusting push rods 48, allowing the air defense door 100 to be lifted and lowered during clamping. By utilizing the cooperation of the adjusting drive worm gear 44 and the adjusting drive worm 43, the rotating support sleeve 46 can be driven to rotate, and when not driven to rotate, the rotating support sleeve 46 can be limited to rotate, thus maintaining the air defense door 100 in the tilted state after adjustment.

[0056] like Figure 1 , 2 As shown in Figure 7, in the double-leaf air-raid shelter door installation system disclosed in this invention, the control cabinet 5 is equipped with a controller, a power module, a charging and discharging circuit, a charging interface, an adjustment drive circuit, a translation drive circuit, a lifting drive circuit, a rotation drive circuit, a first lifting drive circuit, a second lifting drive circuit, an up button, a down button, a first lifting button, a second lifting button, a first release button, a second release button, a left button, a right button, an extension button, a retraction button, a forward rotation button, and a reverse rotation button. The controller is electrically connected to the adjustment drive circuit, the translation drive circuit, the lifting drive circuit, the rotation drive circuit, the first lifting drive circuit, the second lifting drive circuit, the up button, the down button, the first lifting button, the second lifting button, the first release button, the second release button, the left button, the right button, the extension button, the retraction button, the forward rotation button, and the reverse rotation button.

The pull drive circuit and the second lift drive circuit are electrically connected to the adjustment drive motor 42, the translation drive motor 28, the lifting drive motor 14, the rotation drive motor 17, and the two lift drive motors 33, respectively. The adjustment drive circuit, translation drive circuit, lifting drive circuit, rotation drive circuit, first lift drive circuit, and second lift drive circuit all use existing stepper motor drive circuits to perform stepper drive control on the adjustment drive motor 42, translation drive motor 28, lifting drive motor 14, rotation drive motor 17, and two lift drive motors 33, respectively. The power module supplies power to the controller, adjustment drive circuit, translation drive circuit, lifting drive circuit, rotation drive circuit, first lift drive circuit, and second lift drive circuit through the charging and discharging circuit. The charging interface charges the power module through the charging and discharging circuit. The controller can use an existing microcontroller control module to send control commands to the corresponding motor drive circuits based on button triggers.
