Description

Technical Field

[0001] This invention belongs to the field of construction equipment technology, and particularly relates to a modular pneumatic escape device and its installation method. Background Art

[0002] With the acceleration of urbanization, high-rise buildings are increasing, and safety issues during the construction phase are becoming increasingly prominent. However, most existing escape devices are designed for existing buildings, such as slide-type escape devices. These devices are often designed for existing buildings and therefore have disadvantages such as occupying a large amount of structural space, high cost, and slow escape speed. Moreover, for various reasons, most of these devices cannot be used during the construction phase.

[0003] Specifically, existing escape devices suffer from the following shortcomings, which limit their application during the building construction phase:

[0004] 1. Complex installation methods and limitations in technical specifications and applicability: Existing escape devices often require fixed installation points or specific building structures for support, while temporary structures or incomplete building environments during the construction phase can hardly meet these technical specification requirements; in addition, these escape devices often lack design considerations for specific risks during the construction phase.

[0005] 2. Large structural space occupation and high cost, posing economic cost issues: Existing escape devices often require a large amount of structural space, while the space during the construction phase may need to be used for other temporary facilities or storage of construction materials, which limits the installation of escape devices; in addition, the cost of escape devices is usually high, and construction units may not be able to afford these costs with limited budgets, especially during the construction phase, when resources and funds tend to be invested in the construction of the main building structure.

[0006] 3. Complex operation, difficult maintenance and upkeep, and safety and efficiency issues: Existing escape devices are complex to operate and require professional training. However, construction personnel may lack the corresponding training and experience, resulting in their inability to effectively use these devices in emergencies. At the same time, complex escape devices require regular maintenance and upkeep, but the construction phase may lack appropriate maintenance conditions and professional personnel, leading to the devices becoming unusable or having reduced reliability. In addition, the dynamic environment during the construction phase increases the complexity and risk of using escape devices, especially in the construction phase of high-rise buildings, where the shortcomings of existing escape devices in terms of escape efficiency and safety are more prominent.

[0007] 4. Psychological and behavioral characteristics: In emergency situations involving fire hazards, especially when the complexity of fire escape and evacuation in high-rise buildings increases, the psychological and behavioral characteristics of construction workers in temporary structures or incomplete building environments during the construction phase may lead to their inability to effectively use fire rescue escape devices, such as fire rescue air cushions and aerial platform vehicles. Furthermore, these escape devices also have limited single-rescue carrying capacity.

[0008] Therefore, in order to solve the problem of the difficulty of escape for high-rise workers in the event of an emergency during the construction phase, it is urgent to develop and design a modular pneumatic escape device and its installation method specifically for the construction phase. The device can be installed at different heights as the building construction progresses and can quickly and safely help high-rise workers escape from the site, thereby meeting the safety requirements of the construction phase and improving the safety of construction workers. Summary of the Invention

[0009] To address the problems existing in the prior art, the present invention aims to provide a modular pneumatic escape device and its installation method. By modularizing the pneumatic escape device and assembling the upper and lower structural outer frames into a complete structural outer frame unit using standard outer frame fasteners, and further reinforcing components such as gusset plates, wall fasteners, and scissor braces, a safe and stable basic frame structure for the escape device can be provided. The device is easy to install and portable, occupies little structural space, and its height can be increased layer by layer during construction, exhibiting wide adaptability. Furthermore, the suspended rescue basket device in this invention adopts a suspended basket platform form and uses a working mode similar to a passenger / freight elevator, providing a safe and stable escape environment for construction workers and increasing the single rescue capacity, significantly improving escape efficiency and safety. This effectively solves the problem of rapid evacuation of high-rise workers when a dangerous situation occurs during construction and the construction elevator is unusable.

[0010] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0011] In a first aspect, the present invention provides a modular pneumatic escape device, comprising an outer frame, standard section fasteners for the outer frame, wall fasteners, structural reinforcement components, a pneumatic lifting device, a top suspension beam, a suspended rescue basket device, and a control module.

[0012] The outer frame of the structure is a rectangular hollow column structure, symmetrically arranged layer by layer from bottom to top. Longitudinal movable grooves are formed on the opposite end faces of the symmetrically arranged outer frames. The positions of these grooves correspond to the positions of the top suspended beams, allowing the top suspended beams to move vertically. The number of layers of the outer frame is determined based on the building height and the height of the outer frame itself. Two adjacent outer frames are fixedly connected by standard frame section fasteners. Wall fasteners are fixed to the wall, and each outer frame is fixedly connected to the wall via these fasteners. The structural reinforcement component includes a connecting plate, which is positioned between two adjacent outer frames on the same layer, located at the end furthest from the wall, to reinforce and fix adjacent outer frames.

[0013] At each of the four corners of the bottom of the outer frame of the structure located at the bottom layer, a base is welded and fixed. The outer frame of the structure at the bottom layer is fixedly connected to the ground foundation through the bases. The outer frame of the structure at the bottom layer also has a base plate, on which the pneumatic lifting device is fixed. The pneumatic lifting device includes a pneumatic pump, a vent valve, and a first-stage pneumatic cylinder, a second-stage pneumatic cylinder, ... and an nth-stage pneumatic cylinder arranged concentrically from the outside to the inside. The pneumatic pump and the vent valve are both connected to the control module. The control module controls the start and stop of the pneumatic pump and injects gas into each stage of the pneumatic cylinder in sequence to provide lifting power. The control module also controls the opening and closing of the vent valve and discharges the gas in each stage of the pneumatic cylinder in sequence, thereby controlling the pneumatic lifting devices on the left and right sides to perform synchronous vertical lifting and lowering movements. In addition, when all stages of the pneumatic lifting device are fully lifted and extended, the upper surface of the pneumatic lifting device is not lower than the target height of the building.

[0014] The inner side of the outer frame of the structure is provided with several telescopic limiting components. Each telescopic limiting component is horizontally distributed along the height direction of the outer frame of the structure. The telescopic limiting components are signal connected to the control module. The control module controls the telescopic limiting components to perform horizontal telescopic movement, so that the front end of each telescopic limiting component contacts the outer wall of the pneumatic lifting device at the same height, in order to limit the pneumatic cylinders at each level and assist the vertical lifting of each pneumatic cylinder.

[0015] The left and right ends of the top suspended crossbeam pass through the longitudinal movable slots on the left and right sides respectively, and are fixed to the top of the pneumatic lifting device on the left and right sides.

[0016] The suspended rescue basket device includes a basket for carrying people and a fine-tuning suspension mechanism. The basket for carrying people is fixed to the top suspension beam through the fine-tuning suspension mechanism. The fine-tuning suspension mechanism is signal-connected to the control module. The control module controls the fine-tuning suspension mechanism to operate and drive the basket for carrying people up and down to adjust the height of the basket for carrying people.

[0017] As a preferred technical solution, the standard section fastener of the outer frame includes a fixing head and a fastening bolt. The fixing head is provided at the top four corners of the lower outer frame, and a fixing socket is provided at the bottom four corners of the upper outer frame. The fixing socket has a shape that matches the shape of the fixing head. The fixing head at the top of the lower outer frame is inserted into the fixing socket at the bottom of the upper outer frame and locked in place by the fastening bolt.

[0018] As a preferred technical solution, the structural reinforcement component also includes scissor bracing; starting from the second layer of the outer frame, a scissor bracing is provided between every two layers of the outer frame, and the scissor bracing connects the upper and lower layers of the outer frame in a cross shape.

[0019] As a preferred technical solution, the telescopic limiting assembly includes several limiting telescopic rods. The rear ends of the limiting telescopic rods are all fixed to the inner sidewall of the outer frame of the structure. Each of the front ends of the limiting telescopic rods is provided with a sliding roller, and the sliding rollers are all in contact with the outer sidewall of the pneumatic lifting device.

[0020] As a preferred technical solution, each of the pneumatic cylinders is provided with an inlet valve, an outlet valve, and a positioning pin at its bottom. The pneumatic pump and the vent valve are respectively connected to the inlet valve and the outlet valve of the first-stage pneumatic cylinder. The positioning pin is used to fix the pneumatic cylinders after they are lifted into place.

[0021] As a preferred technical solution, the fine-tuning suspension mechanism includes a fine-tuning motor, a fine-tuning pulley, and a fine-tuning suspension rope. The lower end of the fine-tuning motor is fixedly connected to the top of the upper-level suspended basket, and the upper end of the fine-tuning motor is provided with the fine-tuning pulley. The lower end of the fine-tuning suspension rope passes through the fine-tuning pulley and is connected to the fine-tuning motor. The upper end of the fine-tuning suspension rope is fixed to the top suspension beam. The fine-tuning suspension rope can be wound and tightened or loosened as the fine-tuning motor rotates in both directions, thereby driving the upper-level suspended basket to move up and down.

[0022] As a preferred technical solution, the bottom of the suspended platform is also equipped with a telescopic footboard.

[0023] As a preferred technical solution, the height of the outer frame of the structure ranges from 3m to 5m, and the height of the outer frame of the structure is determined according to the height of each floor of the building.

[0024] As a further preferred technical solution, the wall fasteners are pre-embedded in the wall during the pouring of each wall layer.

[0025] A second aspect of the present invention provides a method for installing a modular pneumatic escape device, comprising the following steps:

[0026] S1. Determine the height of the external structural frame based on the single-story height of the building, and determine the number of external structural frames based on the target height of the building. Pre-embed wall fasteners when pouring the walls of each floor.

[0027] S2. Install the outer frame of the bottom structure symmetrically, and fix the outer frame of the bottom structure to the ground and wall through the base and wall fasteners. Reinforce the connection of the outer frames of the bottom structure on the left and right sides with the splicing plate.

[0028] S3. Determine the height of the pneumatic jacking device according to the target height of the building, install the pneumatic jacking device inside the outer frame of the bottom structure and connect it to the control module, and then install the top suspension beam on the pneumatic jacking device.

[0029] S4. Install a suspended rescue basket device on the top suspension beam;

[0030] S5. Based on the current height of the building, install the external frame of each floor in sequence;

[0031] S6. Test whether the pneumatic lifting device is operating normally through the control module, and adjust the extension length of each extension limit component.

[0032] As described above, the present invention has the following beneficial effects:

[0033] (1) The present invention provides a modular pneumatic escape device and its installation method. The device of the present invention has a simple structure and is easy to install. The outer frame of the structure adopts a relatively simple standard section structure. By modularizing the escape device, it has the advantages of light weight, convenient installation and disassembly, low cost and wide range of applications. At the same time, by using a single outer frame as a standard section, the number of required outer frames is determined according to the total height of the building on site and the height of the single outer frame itself. This determines the number of standard section fasteners for fixing two adjacent outer frames. Multiple standard sections of the outer frame are connected together by the standard section fasteners to form a whole, which can adapt to different building heights and expand the range of applications.

[0034] (2) The present invention provides a modular pneumatic escape device and its installation method. The pneumatic lifting device in the pneumatic escape device adopts a dual lifting power mode. By setting a fine-tuning suspension mechanism and combining it with the pneumatic lifting device, different rescue heights can be adjusted at will, ensuring the safety and efficiency of the pneumatic escape device during operation. At the same time, the suspended rescue basket device in this escape device adopts a suspended personnel basket platform, similar to the working mode of a personnel and freight elevator, providing a safe and reliable descent platform that can be used by multiple people at the same time, and significantly improving the rescue speed. In addition, the control module of the pneumatic escape device can work independently to complete the rescue of high-rise personnel without being affected by fire or other related dangers. This satisfies the need to rescue high-rise workers to the ground when a danger occurs at the construction site during the construction phase and the construction elevator cannot be used, so as to achieve the purpose of quickly escaping the scene.

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific direction, and therefore should not be construed as a limitation of this invention.

[0045] Example 1

[0046] like Figures 1-7 As shown, this embodiment provides a modular pneumatic escape device, including an outer frame 11, standard section fixing parts 14, wall fasteners 31, structural reinforcement components, a pneumatic lifting device 4, a top suspension beam 21, a suspended rescue basket device 2, and a control module 8.

[0047] The outer frame 11 is a rectangular hollow column structure. A longitudinal movable groove 112 is provided at the center of one side of the outer frame 11 for the two ends of the top suspended crossbeam 21 to pass through. The outer frame 11 is arranged layer by layer from bottom to top, and the end faces of the outer frame 11 with the longitudinal movable groove 112 are arranged opposite each other. The number of layers of the outer frame 11 is determined according to the height of the building on site and the height of the outer frame 11, so that the height of the uppermost outer frame 11 is not lower than the height of the building on site. Two adjacent outer frames 11 are fixedly connected by the outer frame standard section fastener 14 to form a whole. The standard section fasteners 14 of the outer frame are distributed at the top four corners of the lower outer frame 11. Each standard section fastener 14 includes a fixing head 141 and a fastening bolt. The fastening bolt uses a fixing screw 142 and a fixing nut 143. A fixing head 141 is provided at each of the top four corners of the lower outer frame 11, and a fixing socket is provided at each of the bottom four corners of the upper outer frame 11. The fixing socket has a shape that matches the shape of the fixing head 141, thereby facilitating... The two adjacent structural outer frames 11 are assembled and fixed together; the fixing pile head 141 and the fixing socket are provided with matching fastening bolt holes. The two adjacent structural outer frames 11 are connected by insertion. In operation, the fixing pile head 141 at the top of the lower structural outer frame 11 is inserted into the fixing socket at the bottom of the upper structural outer frame 11, and then locked and fixed by fixing screw 142 and fixing nut 143, so that the two adjacent structural outer frames 11 form a whole and form a reliable connection.

[0048] In this embodiment, the outer structural frame 11 adopts a standard section structure and is made of steel frame material, which has the advantages of light weight, convenient installation and disassembly, low cost, and wide applicability. The height range of the outer structural frame 11 is 3m-5m. In the actual installation process, different height specifications of the outer structural frame 11 can be selected according to the height of each floor of the building at the current construction stage, so that the height of the outer structural frame 11 is not less than the height of a single floor of the building. This facilitates the selection of a suitable outer structural frame 11 and makes it easy to assemble and use the escape device, thus having wide applicability.

[0049] The wall fasteners 31 are fixed to the wall 6, and the back ends of each structural outer frame 11 are fixedly connected to the wall fasteners 31, so that each structural outer frame 11 is fixed to the wall 6 through the wall fasteners 31, forming a stable structural unit. Preferably, the wall fasteners 31 are pre-embedded in the wall 6 and can be set during the pouring of each layer of the wall 6, thereby increasing the structural stability.

[0050] The structural reinforcement component is used to strengthen and fix adjacent structural outer frames 11. The structural reinforcement component includes a connecting plate 32, which is horizontally positioned between two structural outer frames 11 on the same layer. This connects the two opposing structural outer frames 11, enhancing overall stability and preventing interference with the suspended rescue basket device 2. Further, in a preferred embodiment, the structural reinforcement component also includes scissor braces 33. Starting from the second layer of structural outer frames 11, a scissor brace 33 is provided between every two layers of structural outer frames 11, and the scissor braces 33 connect the upper and lower layers of structural outer frames 11 in a cross shape.

[0051] At each of the four bottom corners of the outer frame 11 located at the bottom layer, a base 13 is welded and fixed. The base 13 is securely fixed to the ground 7 using anchor bolts 131. The base 13 increases the stability between the outer frame 11 and the ground 7, and also ensures the stability and levelness of the pneumatic lifting device 4 even on uneven ground 7, thereby improving the reliability and efficiency of the pneumatic lifting device 4. Simultaneously, a base plate 111 is provided at the lower end of the outer frame 11 located at the bottom layer for placing... The pneumatic lifting device 4 is positioned, and the base plate 111 is made of a material with good pressure resistance and wear resistance to withstand pressure and friction during long-term use. In other embodiments, several adjustable support legs are provided below the base plate 111. The height of the adjustable support legs can be adjusted by telescopic extension. The lower end of the adjustable support legs is placed on the ground 7, and the upper end of the adjustable support legs is tightened against the lower end surface of the base plate 111 by telescopic extension to match the ground 7 foundation under different construction stages, and to improve the operational stability of the pneumatic lifting device 4 by increasing support.

[0052] The pneumatic lifting device 4 includes a pneumatic pump 41, a vent valve 42, and concentrically arranged primary pneumatic cylinders 43, secondary pneumatic cylinders 44, ... and n-stage pneumatic cylinders 45 from the outside in. Each stage of the pneumatic cylinders has an inlet valve 47, an outlet valve, and a positioning pin 46 at its bottom. Adjacent stages of the pneumatic cylinders are connected via the inlet valve 47 and the outlet valve. The pneumatic pump 41 and the vent valve 42 are both signal-connected to the control module 8, thereby ensuring synchronous vertical lifting and lowering of the pneumatic lifting devices 4 on both sides. The inlet valve 47 on the primary pneumatic cylinder 43 is connected to the pneumatic pump 41 via the inlet valve 47. The air pipe 411 is connected, and the control module 8 controls the air pump 41 to inject gas into each stage of the air cylinder from the outside to the inside to provide lifting power; the air outlet valve on the first-stage air cylinder 43 is connected to the air release valve 42 through the air outlet pipe, and the control module 8 controls the gas in each stage of the air cylinder to be discharged from the outside to the inside through the air release valve 42; the positioning and fixing pin 46 is used to fix the air cylinder located on the inner side of the two adjacent stages of air cylinders after it has been lifted into place; and when all stages of air cylinders in the air lifting device 4 are fully lifted, the upper end face of the air lifting device 4 is not lower than the target height of the building. In this embodiment, there are two air lifting devices 4, which are respectively set inside the outer frame 11 of the structure on the left and right sides connected to the ground 7, and the air lifting devices 4 are installed at the center of the bottom plate 111 of the corresponding outer frame 11.

[0053] The inner side of the outer frame 11 is also provided with telescopic limiting components 12. Each telescopic limiting component 12 is horizontally distributed along the height direction of the outer frame 11, and the inner end of each telescopic limiting component 12 contacts the outer wall of the pneumatic lifting device 4 at the same height position, used to limit the movement of each stage of the pneumatic cylinder and assist in the vertical lifting and lowering of each stage of the pneumatic cylinder. Each telescopic limiting component 12 includes several limiting telescopic rods 121, and all the limiting telescopic rods 121 within any telescopic limiting component 12 are located on the same horizontal plane. The rear ends of the limiting telescopic rods 121 are all fixed to the inner side wall of the outer frame 11 of the structure. Each front end of the limiting telescopic rod 121 is provided with a sliding roller 122. The limiting telescopic rod 121 is connected to the control module 8 by signal. The control module 8 controls the limiting telescopic rod 121 to perform horizontal telescopic movement, so that the sliding rollers 122 contact the outer side wall of the air cylinder at the corresponding height on the air pressure lifting device 4, so as to limit the air cylinders of each stage of the air pressure lifting device 4 and assist the vertical lifting of each stage of the air pressure cylinder. In this embodiment, two sets of telescopic limiting components 12 are horizontally arranged on the inner side of the outer frame 11, and each set of telescopic limiting components 12 includes eight limiting telescopic rods 121 with rolling pulleys on the top. The eight limiting telescopic rods 121 are evenly distributed in pairs on the four inner sidewalls of the outer frame 11. Each outer frame 11 has 16 limiting telescopic rods 121 on its inner side. That is, the outer frame 11 has two layers of telescopic limiting components 12, each layer has eight limiting telescopic rods 121, and two are distributed on each side. A single outer frame 11 has a total of 16 limiting telescopic rods 121. Preferably, the distance from the limiting telescopic rod 121 to the inner wall of the nearest structural outer frame 11 is greater than the distance from the outer wall of the pneumatic cylinder at the current height of the pneumatic lifting device 4 to the inner wall of the nearest structural outer frame 11, thereby ensuring that after the limiting telescopic rod 121 performs telescopic movement, the rolling pulley can always contact the outer wall of the pneumatic cylinder at the same height.

[0054] The left and right ends of the top suspended beam 21 pass through the longitudinal movable slots 112 on the left and right side outer frames 11, respectively, and are fixed at the top center of the left and right side pneumatic lifting devices 4, that is, fixed at the top center of the innermost n-stage pneumatic cylinder 45 of the pneumatic lifting device 4. During operation, the top suspended beam 21 can move up and down synchronously with the lifting or lowering of the pneumatic lifting devices 4 on both sides. In another embodiment, a spray device 5 is also installed on the lower end face of the top suspended beam 21. The spray device 5 is located above the suspended rescue basket device 2 and is controlled by the control module 8 to start and stop, thereby ensuring the safety within the range of the suspended rescue basket device 2 and reducing the threat of high temperature to escapers and escape devices.

[0055] The suspended rescue basket device 2 includes a person-access basket 22 and a fine-adjustment suspension mechanism 23. The person-access basket 22 is fixed to the top suspension beam 21 via the fine-adjustment suspension mechanism 23, which is used to adjust the height of the person-access basket 22. Specifically, the fine-adjustment suspension mechanism 23 includes a fine-adjustment motor 231, a fine-adjustment pulley 232, and a fine-adjustment suspension rope 233. The lower end of the fine-adjustment motor 231 is fixedly connected to the top of the person-access basket 22, and the upper end of the fine-adjustment motor 231 is provided with the fine-adjustment pulley 232. The lower end of the fine-adjustment suspension rope 233 passes through the fine-adjustment pulley 232 and is wound and fixed to the fine-adjustment motor 231. The upper end of the fine-adjustment suspension rope 233 is fixed to the top suspension beam 21. The fine-tuning motor 231 is signal-connected to the control module 8. The control module 8 controls the fine-tuning motor 231 to rotate forward or backward, causing the fine-tuning suspension rope 233 to tighten or loosen as the fine-tuning motor 231 rotates in both directions. This, in turn, drives the sling basket 22 to move up and down, achieving fine-tuning control of the height of the sling basket 22. This ensures that the height of the telescopic step 221 on the sling basket 22 is consistent with the height of the exit of the floor to be escaped from, thus ensuring a smooth escape for the escaped personnel. The bottom of the sling basket 22 is also equipped with a telescopic step 221, which provides a foothold for the escaped personnel, making it easier for them to enter the sling basket 22 from various floors. Preferably, the length of the telescopic step 221 extending beyond the edge of the sling basket 22 is greater than the distance from the side of the sling basket 22 against the wall 6 to the wall 6, allowing the telescopic step 221 to be attached to the exit of the floor to be escaped from. In this embodiment, there are two fine-tuning suspension mechanisms 23, and each fine-tuning suspension mechanism 23 consists of two fine-tuning motors 231, two fine-tuning pulleys 232, and two fine-tuning suspension ropes 233. The fine-tuning suspension ropes 233 are made of steel strands. The fine-tuning suspension mechanism 23 facilitates flexible adjustment of the personnel basket 22 within a certain height. Preferably, the personnel basket 22 is a hollow frame type basket, and the bottom of the personnel basket 22 is covered with a board, thereby effectively reducing the overall weight of the personnel basket 22 and ensuring the stable operation of the pneumatic lifting device 4.

[0056] Example 2

[0057] like Figure 6 As shown, this embodiment provides an installation method for a modular pneumatic escape device applied to Embodiment 1, including the following steps:

[0058] S1. Determine that the height of the outer frame 11 is not less than the single-story height of the building, and determine the number of outer frames 11 according to the target height of the building to meet the overall height requirements of the building; during construction, when pouring each wall 6, pre-embed wall fasteners 31 to ensure that the length of the wall fasteners 31 protruding from the wall does not exceed the length of the telescopic tread 221.

[0059] S1-1. Determine the height of the structural outer frame 11 according to the building's floor height. The height of the structural outer frame 11 shall not be less than the height of a single floor of the building. Determine the number of structural outer frames 11 according to the target height of the building to ensure that the overall height of the final completed structural outer frame 11 is not less than the target height of the building.

[0060] S1-2. During the construction of each floor wall 6, the wall fasteners 31 are pre-embedded in the wall 6, and the length of the wall fasteners 31 protruding from the wall 6 is not greater than the length of the telescopic pedal 221 extending out of the edge of the upper basket 22, so as to ensure that the telescopic pedal 221 on the escape device completed later can be erected at the exit of the wall 6 of the escape floor of the building.

[0061] S2. The bottom structure outer frame 11 is symmetrically installed, and the bottom structure outer frame 11 is fixedly connected to the ground 7 and the wall 6 through the base 13 and the wall fastener 31. The left and right bottom structure outer frames 11 are reinforced by the connecting plate 32.

[0062] S2-1. Fix a base 13 at each of the four bottom corners of the bottom outer frame 11. Fix the bottom outer frame 11 to the ground 7 through the base 13, ensuring that the side of the outer frame 11 with the longitudinal movable groove 112 is set opposite to each other, and the plane between the left and right longitudinal movable grooves 112 is parallel to the outer surface of the wall 6.
