Description

Technical Field

[0001] This utility model belongs to the field of emergency rescue technology, and in particular relates to an emergency rescue device. Background Technology

[0002] Emergency rescue generally refers to the activities and plans for prevention, preparedness, response, and recovery in response to sudden and destructive emergencies. Depending on the type of emergency, it can be categorized into areas such as health emergencies, transportation emergencies, fire emergencies, earthquake emergencies, factory and mine emergencies, and home emergencies. Generally, rescuers need equipment with cutting, clamping, or spreading functions to facilitate rescue operations. In complex situations, the combined use of cutting and clamping may be necessary. For example, hydraulic clamps may be used to spread the object before hydraulic shears are used to cut it; or hydraulic shears may be used to cut the object before hydraulic clamps are used to pull or compress it.

[0003] Therefore, some existing small manual rescue equipment such as hydraulic spreaders, hydraulic jacks, and crack openers are unable to complete rescue work due to their small size and inability to exert large forces; moreover, they are inefficient in disaster relief. Consequently, emergency rescue devices suffer from poor environmental adaptability, low stability, and weak rescue professionalism. Utility Model Content

[0039] The following is in conjunction with the appendix Figures 1 to 7 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0040] like Figure 1As shown, in one embodiment of this utility model, the emergency rescue device includes a power source component 200, a driven component 300, a gear traction component 500, and at least two movable components 400. The power source component 200 includes a first housing 210 and a drive component 221. The drive component 221 is disposed inside the first housing 210. The driven component 300 includes a second housing 310 and a driven assembly. The second housing 310 is stacked with the first housing 210. The driven assembly is disposed inside the second housing 310 and connected to the drive component 221. The gear traction component 500 is stacked on the upper end of the second housing 310, and the movable end of the gear traction component 500 is connected to the driven assembly. All the movable components 400 are respectively connected to the drive end of the gear traction component 500, so that the movable components 400 can perform closing or opening movements.

[0041] The technical solution of this utility model utilizes the driving force of a driving component and the driven action of a driven component to cause the gear traction component to rotate, thereby causing the movable component 400 to perform closing or opening movements. This enables the movable component 400 to perform closing or opening movements without hydraulic power. This effectively reduces the excessive weight of components such as hydraulic pumps, improves ease of use, and ensures the stability of the movable component's operation. In addition, the stacked gear traction component and second housing, as well as the second housing and the first housing, achieve a more compact structure, reduce its space occupation, and thus improve ease of use and the range of applicable environments.

[0042] Among them, such as Figure 5 As shown, the first housing 210 has a first inner cavity 211; the driving component 221 is connected to the inside of the first inner cavity 211; the second housing 310 has a second inner cavity 311; and the driven component is connected to the inside of the second inner cavity 311. The first inner cavity 211 and the second inner cavity 311 can improve the protection of the driving component 221 and the driven component, preventing them from being directly damaged by the outside world.

[0043] The gear traction component 500 and the power source component 200 are both located on the same outer end of the second housing 310. This structure effectively improves the structural compactness of the emergency rescue device and ensures the smoothness and stability of its drive operation.

[0044] Among them, the driving component 221 is a drive motor; through the drive of the drive motor and the traction of the gear traction component 500, the movable component 400 can be driven to close or open without hydraulic power; thereby effectively reducing the weight of the emergency rescue device, improving the convenience of use, and ensuring the stability of the movable component's operation.

[0045] Among them, such as Figure 5As shown, the power source component 200 also includes a drive traction component 222; one end of the drive traction component 222 is connected to a drive motor; the other end of the drive traction component 222 is connected to a driven component. Further, as... Figure 5 As shown, the drive traction component 222 includes a first traction wheel 2221, a traction shaft 2222, and a second traction wheel 2223; the interior of the first traction wheel 2221 is connected to the motor shaft of the drive motor; the first traction wheel 2221 is connected to the second traction wheel 2223 via a traction chain; the middle part of the second traction wheel 2223 is connected to one end of the traction shaft 2222; the other end of the traction shaft 2222 passes through the first inner cavity 211 and into the second inner cavity 311; and the other end of the traction shaft 2222 is connected to the driven component.

[0046] Specifically, in some implementations, such as Figure 2 As shown, the gear traction component 500 includes a limiting component 510 and a gear mechanism 520; the mounting end of the limiting component 510 is connected to the first housing 210; the limiting end of the limiting component 510 is connected to the top of the gear mechanism 520; the bottom of the gear mechanism 520 is mounted on the second housing 320 and connected to the driven assembly; the side end of the gear mechanism 520 is connected to the movable component 400. Wherein, as... Figure 2 and 3As shown, the gear mechanism 520 includes a stationary fixed block 521, a connecting component, a rotating block 522, a traction gear 5231, a traction rod 5232, and at least two mounting blocks 416; the connecting component includes a first rotating gear 5211, a connecting rod 5212, and a second rotating gear 5213; one end of the traction rod 5232 passes through the rotating block 522 and the stationary fixed block 521 respectively, and is movably connected to the inner top (middle bearing) of the rotating block 522; one mounting block 416 is connected to the stationary fixed block 521, and the other mounting block 416 is connected to the rotating block 522; the other end of the traction rod 5232 passes through the second housing 320 and is connected to the driven component; the traction gear 5231... The connecting rod 5212 is connected to the outer surface of the traction rod 5232 and is located inside the stationary fixed block 521. There are two rotating blocks 522, which are rotatably located at the upper and lower ends of the stationary fixed block 521 (their bottoms are connected to the rotating column). The inner wall of the rotating block 522 is provided with a traction tooth surface 5221. The first rotating gear 5211 is located inside the stationary fixed block 521 and is connected to the traction tooth surface 5221 and the traction gear 5231 respectively. The two ends of the connecting rod 5212 are fixedly connected to the first rotating gear 5211 and the second rotating gear 5213 respectively. The second rotating gear 5213 is located inside the rotating block 522 and is connected to the traction tooth surface 5221. In other words, after the driving component 221 is driven, it causes the driven component to rotate, thereby pulling the traction rod 5232 and the traction gear 5231 to rotate. The rotation of the traction gear 5231 drives the rotation of the first rotating gear 5211, the connecting rod 5212, and the second rotating gear 5213, thereby pulling the stationary fixed block 521 to remain stationary, and pulling the rotating blocks 522 on the upper and lower sides to move towards or in opposite directions relative to the stationary fixed block 521, thus achieving opening or closing motion. In some embodiments, such as... Figure 2 and 4 As shown, the limiting component 510 includes a positioning block 511, a rotating component 512, and a limiting handle 513. The positioning block 511 is connected to the first housing 210. One end of the rotating component 512 is connected to the gear mechanism 520. The other end of the rotating component 512 passes through the positioning block 511 and is rotatably connected to the positioning block 511. The other end of the rotating component 512 is detachably connected to the limiting handle 513 via a thread. In other words, by fixing one end of the rotating component 512 and allowing it to rotate, the positioning block 511 and the rotating component 512 can move correspondingly, enabling the gear mechanism 520 and the movable component 400 to swing within a certain range (70 degrees), thus enabling use in more diverse scenarios. Specifically, the movable component 400 allows the tool to operate at different angles in confined spaces and restricted positions, improving the ease of use of the tool. Furthermore, as... Figure 4As shown, the rotating component 512 includes a first connecting rod 5121 and a first connecting block 5123; one end of the first connecting rod 5121 is detachably connected to the limiting handle 513 via a thread; the other end of the first connecting rod 5121 passes through the positioning block 511 and is connected to the first connecting block 5123; the first connecting block 5123 is connected to the gear mechanism 520. Further, as... Figure 4 As shown, the first connecting rod 5121 has a limiting protrusion 5122 on its side end, and the positioning block 511 has a limiting groove 5111 inside, with the width of the limiting groove 5111 being greater than the width of the limiting protrusion 5122. In other words, the limiting groove 5111 of a suitable width ensures the limiting effect on the first connecting rod 5121 and also allows the first connecting rod 5121 to rotate within a certain range, adapting to various environments. Specifically, by rotating the gear mechanism 500 and the movable part 400, the first connecting rod 5121 rotates within the limiting groove 5111. Simultaneously, the rotation of the traction rod 5232 allows the gear mechanism 500 and the movable part 400 to rotate within a certain range, adapting to various environments.

[0047] Specifically, in some implementations, such as Figure 4 and 5 As shown, the first housing 210 is provided with a first limiting plate 810 and a second limiting plate 820 disposed opposite to each other; and a limiting cavity 801 is provided between the first limiting plate 810, the second limiting plate 820 and the first housing 210; the gear traction component 500 is disposed inside the limiting cavity 801, and one end of the gear traction component 500 passes through the second limiting plate 820. This structure, through the limiting effect of the first limiting plate 810 and the second limiting plate 820, can effectively prevent the gear traction component 500 and the moving component 400 from falling off, thereby improving the stability and safety of use. For example, Figure 2 and 4 As shown, the bottom of the gear traction component 500 is provided with an abutment plate 530, which abuts against the second limiting plate 820.

[0048] Specifically, in some implementations, such as Figure 5 As shown, the driven assembly includes a first driven wheel 320, a transmission chain 330, and a second driven wheel 340. The first driven wheel 320 is movably connected to the interior of the second inner cavity 311 and is connected to the movable end of the traction shaft 2222. The transmission chain 330 is arranged around the surfaces of the first driven wheel 320 and the second driven wheel 340. The bottom of the gear traction component 500 (traction rod 5232) is fixedly connected to the middle of the second driven wheel 340. This structure, through the mutual transmission of multiple sets of driven wheels, can ensure the stability of driven traction and also ensure the stress of closing or opening, improving the smoothness of use.

[0049] Specifically, in some of these implementations, such as Figure 6 As shown, the movable component 400 is an expansion clamp rod 410; the expansion clamp rod 410 includes an expansion inclined section 411, a first straight section 412, and a second straight section 413 connected in sequence. The second straight section 413 is connected to the gear traction component 500 (the first connecting block 416 in the middle). The expansion clamp rod 410 includes a stationary clamp rod and a movable clamp rod; the stationary clamp rod is connected to a stationary fixed block 521; the movable clamp rod is connected to a rotating block 522. This structure, through multi-segment contact expansion, can increase the contact area, thereby increasing the expansion support stress and ensuring the orderly progress of the expansion operation. For example, Figure 6 As shown, the outer surface of the expansion inclined section 411 is provided with at least two first protrusions 417, which are arranged in an increasing stepped manner from the first straight section 412 toward the expansion inclined section 411; the outer surface of the first straight section 412 is provided with at least two second protrusions 414, which are arranged at equal intervals; the outer surface of the second straight section 413 is provided with a third protrusion 415; and the protrusion thickness of the third protrusion 415 is greater than that of the second protrusion 414. Further, the first protrusions 417 are square or rectangular protrusions; the second protrusions 414 are trapezoidal protrusions. This structure increases the contact area through multiple protrusions in multiple segments, and the lifting effect can be improved under the strong driving force of the gear traction component 500, which can further increase the lifting stress, thereby ensuring the orderly progress of expansion rescue.

[0050] Specifically, in other implementations, such as Figure 7 As shown, the movable component 400 is a cutting lever 420; and the inner end of the cutting lever 420 is provided with a cutting surface 422; one end of the cutting lever 420 is connected to the gear traction component 500. The cutting lever 420 includes a stationary lever and a movable lever; the stationary lever is connected to a stationary fixing block 521; and the movable lever is connected to a rotating block 522. This structure, through the strong driving force of the cutting lever 420 and the gear traction component 500, can improve the cutting effect while also ensuring the overall structural lightness.

[0051] In other words, the emergency rescue device has expansion clamps 410 and shearing clamps 420 of different types, and each tool head can be quickly replaced according to the needs of the rescue response (e.g., in about 20 seconds). Furthermore, the tool heads will have different designs depending on the functional requirements.

[0052] Specifically, in some implementations, such as Figure 1As shown, the emergency rescue device also includes a power supply component 100; the power supply component 100 is stacked on top of the power source component 200 and is positioned opposite to the driven component 300. The power supply component 100 is a battery; that is, by mounting the battery on top of the power source component 200, the battery can be easily installed and removed, and power can be provided, thereby reducing the need for excessively long power cables and enabling use in multiple scenarios. The battery is a PWR-L i2X lithium-ion battery pack (13.2V lithium-ion battery); its weight is 1.3kg. During rescue operations, the PWR-L i2X lithium-ion battery pack (13.2V lithium-ion battery) allows for rescue work in any harsh environment (including low temperature, low pressure, etc.), thereby significantly reducing casualties in a short time. This solves the problem that most current rescue tools on the market cannot be used in low temperature or confined environments, especially those using hydraulic tools. Furthermore, its lightweight design (1.3kg) and 13.2V capacity make it more portable and meet aviation transport standards. In addition, when the lithium battery pack is low on power, the PWR-Li2X lithium-ion battery pack (13.2V lithium-ion battery) can be removed from the main unit, and the main unit can be connected to the car's 12V battery via a 12V adapter and battery clips to obtain the corresponding power.

[0053] Specifically, in some implementations, such as Figure 1 As shown, the emergency rescue device also includes a handle ring 600 and a handle bracket 700; the two ends of the handle bracket 700 are respectively connected to the two opposite end faces of the power source component 200; the handle ring 600 is connected to the back end of the power source component 200 and is positioned away from the gear traction component 500. The handle bracket 700 is a U-shaped handle bracket; the handle ring 600 is a circular handle bracket. In other words, during use, the operator can hold both the U-shaped handle bracket and the circular handle bracket to adapt to more different scenarios, thereby improving ease of use.
