Description

Technical Field

[0001] This utility model belongs to the field of fire protection technology, and specifically relates to a mobile multifunctional support frame. Background Technology

[0002] In the firefighting field, support frames, as a basic auxiliary tool, are widely used to support and carry rescue equipment and materials. However, as the demands for efficiency, flexibility, and versatility in firefighting continue to increase, traditional support frames are gradually revealing their limitations and failing to meet the diverse needs of modern firefighting operations. Most traditional support frames are designed with a fixed height, making it difficult to change the height once installed. This design is extremely inconvenient when dealing with rescue equipment at different heights or different operational requirements. For example, during a rescue operation, firefighters may need to adjust the support frame according to the height of different floors to better support rescue equipment or materials. However, fixed-height support frames cannot meet this need, forcing firefighters to frequently replace frames at different heights, increasing workload and time costs. Therefore, we need to propose a mobile, multi-functional support frame to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a mobile, multi-functional support frame. Through a lifting component, the height of the support frame can be flexibly adjusted according to different usage scenarios and the required height of objects. This height adjustment function allows the support frame to adapt to various fire rescue work scenarios, especially in special environments such as deep well rescues and high-altitude rope rescues. Traditional rope rescue support devices often have a fixed structure, making it difficult to quickly adapt to changes in the environment when facing rescues at different depths in wells, vertical rescues within limited space in buildings, or rescues in complex terrains such as mountains and canyons, resulting in low rescue efficiency. This invention, with its adjustable height, convenient mobility, and rapid assembly, can significantly improve the operational efficiency of fire rescue personnel in various rope rescue scenarios, shorten rescue response time, increase rescue success rate, and thus better protect the lives of trapped personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile multifunctional support frame, including a base, a top plate mounted on the base, a crossbeam mounted on the top plate, a lifting component for adjusting the height of the support frame between the base and the top plate, and the lifting component, base, and top plate are all detachable.

All four sets of columns and lifting grooves are hollow.

[0006] Furthermore, each of the four sets of columns and lifting rods has multiple sets of positioning holes, which are equidistantly arranged. The columns and lifting rods are fixed by positioning pins and positioning holes.

[0007] Furthermore, the load-bearing component includes two sets of support plates, with both ends of the two sets of support plates respectively mounted on four sets of columns, and the two sets of support plates are arranged in parallel. Limiting columns are fixedly installed on both sets of support plates.

[0008] Furthermore, a load-bearing plate is detachably provided between the two sets of support plates, and each end of the load-bearing plate is provided with a limiting hole for use with the limiting post.

[0009] Furthermore, the two sets of support plates are provided with connecting holes that cooperate with the positioning holes, and the support plates are fixed to the column by positioning pins.

[0010] Furthermore, the movable component includes four sets of brake casters, which are detachably mounted on two sets of columns. Each of the four sets of brake casters is provided with a screw that is inserted into a positioning hole, and each of the four sets of screws is threaded with a nut.

[0011] Furthermore, the base and the top plate are each provided with four sets of mounting blocks. Each of the four sets of mounting blocks has a mounting groove for insertion into the column and the lifting rod.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a mobile multifunctional support frame.

[0025] The system includes a base 110, a top plate 120 mounted on the base 110, a crossbeam 130 mounted on the top plate 120, a lifting assembly for adjusting the height of the support frame between the base 110 and the top plate 120, and the lifting assembly, the base 110, and the top plate 120 are all detachable. The lifting assembly is detachably equipped with a moving component to facilitate the movement of the support frame, and a load-bearing component for supporting objects is mounted on the lifting assembly.

[0026] The base 110 and top plate 120 provide a stable support platform, the lifting assembly allows for flexible adjustment of the frame height, the moving assembly enables the entire frame to be easily moved to the required position, and the load-bearing assembly is used to support and secure items. This design not only improves the versatility and adaptability of the frame but also facilitates transportation and storage through its detachable design. In deep well rescue operations, the base 110 can be firmly placed around the well opening, ensuring the stability of the entire support frame; the top plate 120 and crossbeam 130 provide solid mounting points for the rope system, enabling firefighters to safely descend into the well.

[0027] In practical fire and rescue applications, the stability of the base 110 is crucial to the entire rescue process. For example, during rescue operations involving urban underground pipeline accidents, the base 110 needs to be placed on potentially damp or uneven ground, requiring its design to incorporate anti-slip and self-adjusting functions. The base 110 features a wide design, increasing the contact area with the ground and improving overall stability. Simultaneously, the addition of anti-slip pads on the bottom enhances its adaptability to various terrains, ensuring the safety of rescuers and those being rescued is not compromised during deep well rescues.

[0028] The lifting assembly includes four sets of columns 210. One end of each of the four sets of columns 210 is detachably mounted on the base 110. The other end of each of the four sets of columns 210 is provided with a lifting groove. Lifting rods 220 are slidably connected in each of the four sets of lifting grooves. The ends of the four sets of lifting rods 220 away from the columns 210 can be detachably mounted on the top plate 120. All four sets of columns 210 and lifting grooves are hollow.

[0029] The lifting assembly, through the design of four sets of columns 210 and lifting rods 220, achieves flexible height adjustment of the support frame. One end of the column 210 is detachably mounted on the base 110, and the lifting rod 220 is slidably connected in the lifting slot at the other end. The other end of the lifting rod 220 is detachably mounted on the top plate 120. This design not only improves the flexibility of the frame but also reduces the overall weight through its hollow structure, facilitating movement and adjustment. This height adjustment function is particularly important in deep well rescue operations, as different wellhead heights and surrounding environments often require different support heights. For example, when rescuers need to conduct rescues in urban underground pipe networks, the wellhead may be located at different heights. By adjusting the height of the lifting assembly, it can be ensured that the rope system can be correctly positioned, allowing rescuers to descend smoothly into the well for rescue. Simultaneously, this adjustability also allows the support frame to adapt to various rescue scenarios, such as vertical rescues in high-rise buildings and rope rescues in mountain canyons.

[0030] In fire and rescue practice, the material selection for the support column 210 and the lifting pole 220 is also crucial. Considering the complexity and harshness of the rescue environment, these components are made of high-strength aluminum alloy. This ensures sufficient strength and rigidity to withstand various loads during rope rescues; furthermore, the lightweight nature of aluminum alloy makes the entire support frame easier to carry and deploy, especially in emergency rescue situations requiring rapid response. The hollow design not only reduces weight but also improves the strength-to-weight ratio of the structure, allowing the support frame to maintain sufficient load-bearing capacity and stability while remaining relatively lightweight.

[0031] Each of the four sets of columns 210 and lifting rods 220 has multiple sets of positioning holes 230, which are equidistantly arranged. The columns 210 and lifting rods 220 are fixed by positioning pins and positioning holes 230.

[0032] The column 210 and lifting rod 220 are stably fixed after height adjustment through the design of positioning holes 230 and positioning pins. The positioning holes 230 are equidistantly arranged on the column 210 and lifting rod 220. Positioning pins are inserted into the corresponding positioning holes 230 to ensure that the column 210 and lifting rod 220 are stably fixed at the adjusted height. This design not only improves the accuracy of adjustment but also ensures the stability of the frame during use through the fixing of the positioning pins. This stability is particularly important in deep well rescue operations, as any shaking or instability could lead to safety risks for rescue personnel working underground.

[0033] The equidistant design of the positioning holes 230 allows firefighters to precisely adjust the height of the support frame according to the specific well depth and rescue needs. For example, during underground pipeline accident rescues, the initial position of the rope system may need to be adjusted depending on the well depth. With the equidistant positioning holes 230, rescuers can quickly and accurately set the height of the support frame based on the pre-calculated depth, reducing rescue preparation time and improving rescue efficiency. Meanwhile, the positioning pins are made of high-strength alloy steel, ensuring that they will not bend or break under high load conditions, providing reliable connection and fixation for the entire support system.

[0034] In actual rope rescue operations, rescuers typically need to install various rescue equipment on the support frame, such as rope pulleys, safety locks, and descenders. The design of the positioning hole 230 facilitates the installation of these devices. Rescuers can select the positioning hole 230 at an appropriate height to install auxiliary equipment, meeting different rescue needs, depending on the equipment's installation requirements. For example, in deep well rescues, multiple pulleys may be needed to change the rope direction. By installing pulley supports at positioning holes 230 at different heights, complex rope systems can be constructed to meet specific rescue requirements.

[0035] The load-bearing component includes two sets of support plates 410. The two ends of the two sets of support plates 410 are respectively installed on four sets of columns 210, and the two sets of support plates 410 are arranged in parallel. Limiting columns 430 are fixedly installed on both sets of support plates 410.

[0036] A load-bearing plate 440 is detachably provided between the two sets of support plates 410. Both ends of the load-bearing plate 440 are provided with limiting holes 450 for use with limiting posts 430.

[0037] The load-bearing component provides stable support for objects through the design of two sets of support plates 410 and a load-bearing plate 440. The two ends of the support plate 410 are mounted on the uprights 210, and the limiting posts 430 are fixed to the support plate 410. The load-bearing plate 440 is detachably installed between the two sets of support plates 410, engaging with the limiting posts 430 through limiting holes 450. This design not only improves the load-bearing capacity but also allows for easy adjustment of the position and number of load-bearing plates 440 as needed through its detachable design. During deep well rescue operations, the load-bearing component can be used to support rope systems, rescue equipment, and even rescued personnel.

[0038] The load-bearing components are designed with diverse needs in fire and rescue operations in mind. For example, during deep well rescues, the load-bearing plate 440 can be used as a temporary working platform for rescuers to prepare at the wellhead; it can also support the rope pulley system, ensuring smooth rope movement and preventing damage from friction. Furthermore, the detachable design of the load-bearing plate 440 makes the entire system more flexible. Rescuers can adjust the position or number of load-bearing plates 440, or even remove unnecessary load-bearing plates, depending on the specific rescue situation, to reduce overall weight and improve equipment mobility.

[0039] In practical rescue applications, the support plate 410 and load-bearing plate 440 typically need to withstand significant loads, thus requiring special consideration in their material and structural design. The support plate 410 is made of high-strength alloy material, possessing excellent strength and rigidity, enabling it to remain stable in various harsh environments. The load-bearing plate 440 features an anti-slip design with a special textured surface, ensuring a stable standing platform for rescuers even in wet or oily environments. Furthermore, the edges of the load-bearing plate 440 are rounded to prevent sharp corners from injuring rescuers or equipment, thus improving the overall system safety.

[0040] The two sets of support plates 410 are provided with connecting holes 420 that cooperate with the positioning holes 230. The support plates 410 are fixed to the column 210 by positioning pins.

[0041] The support plate 410 achieves a stable connection with the column 210 through the design of the connecting hole 420 and the positioning hole 230. The connecting hole 420 cooperates with the positioning hole 230 on the column 210, and the support plate 410 is fixed to the column 210 by a positioning pin. This design not only improves the installation stability of the support plate 410, but also, through its detachable design, facilitates the adjustment of the position and angle of the support plate 410 as needed. During deep well rescue operations, this flexibility allows rescuers to adjust the position of the support plate 410 according to the shape of the wellhead and the surrounding environment, ensuring the stable operation of the rescue equipment.

[0042] The design of the connection hole 420 also takes into account various complex situations that may be encountered during rescue operations. For example, in some deep well rescue scenarios, the wellhead may not be a standard circle, but an irregular shape, or there may be obstacles around the wellhead affecting the placement of the support frame. By adjusting the position and angle of the support plate 410, the entire support system can better adapt to these non-standard conditions, ensuring the smooth progress of the rescue operation.

[0043] In fire and rescue practice, the support plate 410 is not only part of the load-bearing components but can also serve as a mounting platform for other equipment. For example, during deep well rescue operations, it may be necessary to install lighting, communication, or monitoring equipment around the wellhead. The connection holes 420 on the support plate 410 can provide mounting points for these auxiliary devices, making the entire rescue system more complete and efficient. The design of the support plate 410 also takes this versatility into account, with sufficient space and mounting points reserved on its surface to install various auxiliary equipment as needed, thereby improving the overall rescue capability.

[0044] The movable component includes four sets of brake casters 310, which are detachably mounted on two sets of columns 210. Each of the four sets of brake casters 310 is provided with a screw 320 that is inserted into a positioning hole 230, and each of the four sets of screws 320 is threaded with a nut 330.

[0045] The movable component utilizes four sets of brake casters 310 to enable flexible movement of the support frame. The brake casters 310 are detachably mounted on the column 210 and secured in the positioning holes 230 on the column 210 via screws 320 and nuts 330. This design not only improves the frame's mobility but also ensures its stability during use through a braking function, preventing accidental movement. During deep well rescue operations, this mobility allows rescuers to quickly move the support frame to the optimal position, saving valuable rescue time.

[0046] The Brake Caster 310 is designed with the complexity of rescue environments in mind. In real-world rescue scenarios, the ground may be uneven, contain various obstacles, or be soft soil or gravel. The Brake Caster 310 features a large diameter and wide wheel surface, enhancing its adaptability to uneven terrain and ensuring the support frame can move smoothly. Simultaneously, the wheel surface is made of a special rubber material, improving grip and wear resistance, enabling it to adapt to various ground conditions and maintain excellent mobility.

[0047] The braking function is particularly important during rescue operations. Once the support frame is in place, rescuers can immediately lock the brake casters 310 to ensure the support frame remains stable and provides a stable platform for subsequent rescue operations. The braking mechanism employs a double-locking design, locking both the rotation of the wheels and the direction of the caster shaft, ensuring the support frame remains stable in any direction and will not move due to external forces. This double-locking function is crucial for ensuring safety during rescue operations, especially in deep well rescues, where any instability could lead to serious accidents.

[0048] The design of screw 320 and nut 330 also reflects the reliability and ease of operation of the entire system. Screw 320 is made of high-strength alloy material, capable of withstanding large shear and tensile forces, ensuring a firm and reliable connection between brake caster 310 and column 210. Nut 330 features an anti-loosening design to prevent loosening due to vibration or impact during use, further improving the reliability of the entire system. At the same time, the design of screw 320 and nut 330 also considers the ease of operation for rescue personnel in emergency situations, employing an easy-to-grip shape and size, allowing rescue personnel to easily complete installation and adjustment operations even while wearing gloves.

[0049] In fire rope rescue, the detachable nature of the moving components provides additional flexibility. In certain special rescue scenarios, such as in confined spaces or challenging terrain, wheeled support frames may not be usable. In these situations, rescuers can quickly remove the brake casters 310, allowing the support frame to be placed directly on the ground, or employ other securing methods to ensure its stability. This detachable design enhances the adaptability of the entire system, enabling it to cope with various complex rescue environments.

[0050] The base 110 and the top plate 120 are each provided with four sets of mounting blocks 140. Each of the four sets of mounting blocks 140 has a mounting groove 150 for insertion into the column 210 and the lifting rod 220. The side wall of each mounting block 140 has a mounting hole 160 for use with the positioning hole 230. The column 210 and the lifting rod 220 are respectively mounted on the base 110 and the top plate 120 by positioning pins.

[0051] The base 110 and top plate 120, through the design of mounting blocks 140 and mounting slots 150, achieve stable installation of the column 210 and lifting rod 220. The mounting slots 150 on the mounting blocks 140 interlock with the column 210 and lifting rod 220, and the column 210 and lifting rod 220 are fixed to the base 110 and top plate 120 through the cooperation of positioning pins and mounting holes 160. This design not only improves installation stability but also facilitates transportation and storage through its detachable design, enhancing the frame's versatility and adaptability. In fire rope rescue, this stable connection ensures that the entire support system can withstand various loads and stresses during rope rescue operations.

[0052] The design of mounting block 140 fully considers various complex situations that may be encountered during fire rescue operations. Made of high-strength alloy material, mounting block 140 maintains structural integrity under high load conditions, ensuring reliable connections. The dimensions and shape of mounting groove 150 are precisely designed to fit tightly with column 210 and lifting rod 220, reducing gaps and potential loosening at the connection points and improving the overall system stability. Simultaneously, the number and distribution of mounting blocks 140 are optimized to ensure that the load is evenly distributed on base 110 and top plate 120, avoiding structural risks caused by localized stress concentration.

[0053] The design of mounting hole 160 also reflects the ease of operation and safety of the entire system. Mounting hole 160 features a through-hole design, allowing the locating pin to pass completely through mounting block 140 and column 210 or lifting rod 220, providing maximum connection strength. Simultaneously, the mounting hole 160 is precisely aligned with the locating hole 230 on column 210 and lifting rod 220, enabling rescue personnel to quickly complete the installation operation and reduce preparation time. The locating pin employs a quick-lock design, with one end fixed and the other end equipped with a spring-loaded locking mechanism, allowing rescue personnel to complete installation and disassembly operations without tools, improving the system's operational convenience.

[0054] In fire rescue practice, the connection stability between the base 110 and the top plate 120 is crucial to the entire rescue process. Especially during deep well rescues, the base 110 typically needs to withstand significant downward forces, while the top plate 120 needs to support the rope system and potential upward forces. Through the combined design of the mounting block 140, mounting groove 150, and mounting hole 160, the entire system can form a stable mechanical structure, distributing various forces across the entire frame to ensure the system's stability and safety.

[0055] In actual rope rescue operations, the efficiency of assembling and disassembling the support frame is a crucial factor affecting the rescue outcome. The design of the mounting block 140 allows for rapid assembly and disassembly of the entire support frame without the need for complex tools, significantly reducing preparation time. For example, in rescue operations following urban underground pipeline accidents, rescuers may need to deploy the support frame quickly to begin the rescue operation. Through the simplified installation design, rescuers can assemble the support frame within minutes, rapidly commencing the rescue operation and buying precious survival time for those trapped.

[0056] Application examples of this utility model in fire rope rescue:

[0057] Case 1: Rescue Operations for Urban Underground Pipeline Accidents

[0058] A sudden underground pipeline rupture in a city trapped several workers inside, creating a critical situation. Upon receiving the alarm, the fire and rescue team quickly arrived at the scene with this new type of mobile multi-functional support frame. The scene was complex, with uneven ground around the manhole and limited space. Rescuers, based on the situation, placed the base 110 around the manhole and adjusted the height of the four sets of uprights 210 and the lifting rod 220 to position the top plate 120 optimally, providing a stable support point for the rope system. Simultaneously, a working platform was installed in the middle of the frame using load-bearing components for rescuers to use when operating the rope system.

[0059] During this rescue operation, the height adjustment function of the support frame played a crucial role. Due to the low location of the wellhead, rescuers needed to adjust the support frame to a lower height to safely descend into the well for the rescue. Through the coordination of the positioning hole 230 and the positioning pin, rescuers could precisely adjust the height of the support frame, ensuring their smooth entry into the well and the safe evacuation of the rescued person to the surface.

[0060] The design of the brake caster 310 also demonstrated its value in this rescue. Rescuers first pushed the support frame near the wellhead, then locked the brake caster 310 to ensure the support frame remained stable during the rescue. This design allowed rescuers to quickly deploy equipment within a limited space, gaining valuable rescue time.

[0061] Throughout the rescue operation, the support frame demonstrated its excellent stability and load-bearing capacity, successfully supporting the rope system and rescue personnel, ultimately leading to the safe rescue of the trapped worker. After the rescue, the support frame was quickly dismantled and loaded onto rescue vehicles, ready for the next rescue mission.

[0062] Case 2: Deep Well Rescue in Mountainous Areas

[0063] In a mountainous area, a villager accidentally fell into an abandoned well while inspecting it. The well was approximately 20 meters deep and had a narrow opening. Due to the complex terrain, conventional rescue equipment was difficult to transport to the scene. The fire and rescue team carried the mobile multi-functional support frame of this invention, transported it to the nearest road using a four-wheel drive vehicle, and then had rescuers manually carry it to the accident site.

[0064] Upon arrival at the scene, rescuers found that the terrain around the wellhead was uneven and the space was narrow, making conventional rescue methods difficult to implement. At this point, the modular design advantages of this invention became apparent. Rescuers quickly removed the brake casters 310 and placed the base 110 directly on the ground around the wellhead. Through simple adjustments, the base 110 was made adaptable to the uneven ground. Then, based on the location and shape of the wellhead, the heights of the four sets of columns 210 and the lifting rod 220 were adjusted so that the top plate 120 could be correctly positioned above the wellhead.

[0065] In this rescue operation, the detachable and height-adjustable features of the support frame played a crucial role. Due to transportation limitations in the mountainous area, rescuers needed to disassemble the support frame into smaller components for easy manual transport. Upon arrival at the site, the support frame was quickly deployed through simple assembly steps. Simultaneously, due to the unique location of the wellhead, rescuers needed to precisely adjust the height and position of the support frame to ensure the rope system was correctly positioned, creating conditions for the well-entry rescue.

[0066] The load-bearing components also played a crucial role in this rescue. Rescuers installed a specially designed pulley system on support plate 410 to change the direction of the ropes, allowing them to descend to the bottom of the well more safely. Meanwhile, support plate 440 provided a stable support platform for the rescue equipment, ensuring the smooth progress of the entire rescue operation.

[0067] After careful preparation and operation, rescuers successfully descended into the well and safely rescued the trapped person. Throughout the rescue process, the support frame demonstrated its adaptability and reliability in complex environments, providing strong support for the successful rescue.

[0068] Case 3: Vertical Rescue Inside a High-Rise Building in the City

[0069] In a high-rise building in a city, a worker became trapped in an elevator shaft during maintenance and required vertical rescue. Due to the confined space inside the elevator shaft, conventional rescue equipment was difficult to deploy. The fire and rescue team arrived at the scene with this utility model's mobile multi-functional support frame, facing the challenge of deploying rescue equipment within the limited space.

[0070] Rescuers first assessed the situation and found that while space at the elevator shaft opening was limited, there was sufficient flat area around it to place the support frame. By adjusting the position and orientation of the base 110, rescuers were able to securely place the support frame on the flat surface near the elevator shaft opening. Then, by precisely adjusting the height of the four sets of uprights 210 and the lifting rod 220, the top plate 120 was correctly positioned above the elevator shaft opening, providing a support point for the rope system.

[0071] In this rescue operation, the precise height adjustment function of the support frame was particularly important. Due to the special structure of the elevator shaft, rescuers needed to adjust the support frame to a specific height so that the rope system could be correctly aligned with the location of the trapped person inside the shaft. Through the cooperation of positioning holes 230 and positioning pins, rescuers could adjust the height of the support frame with centimeter-level precision, ensuring the accuracy of the rescue operation.

[0072] The movable components also played a crucial role in this rescue. Because the support frame needed to be moved inside the building, the braked casters 310 allowed rescuers to easily push the support frame into the optimal position and then lock the brakes to ensure the support frame remained stable during the rescue. This design significantly reduced manpower requirements and improved rescue efficiency.
