Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rescue apparatus, especially to a multi-person combined force rescue tripod. BACKGROUND

[0002] The existing unpowered rescue tripod system usually comprises four core modules of a triangular support main body, a sling assembly, a manual capstan and an annular protection chain. When implementing vertical rescue operation, the operator needs to control the load lifting through a single capstan drive mechanism. However, the structure design has the following significant technical bottlenecks:

[0003] Defects in ergonomics: the capstan transmission system is only configured with a single drive shaft interface, which results in that even in the scene where there are sufficient rescue personnel, the synchronous force exertion mechanism is still missing, and multiple people cannot be driven cooperatively. Research shows that two-person cooperative operation can improve the load lifting efficiency by 60%-80%, but the existing structure forces the additional human resources to be idle.

[0004] Insufficient power input redundancy: when encountering an overrated load (such as >200kg) or complex terrain, single-point driving is easy to cause instantaneous torque overload of the gear box, causing abnormal wear of the worm transmission system, and the failure rate is increased by about 40%.

[0005] Risk of losing dynamic balance: due to the lack of multi-directional force coupling mechanism, asynchronous human input will cause the sling tension to fluctuate, significantly increasing the stress concentration risk of the protection chain.

Therefore, it is urgent to develop a multi-person combined force rescue tripod, which can involve multiple people to lift the capstan, jointly shake the capstan to lift the heavy object, fully exert the rescue force, and increase the weight and speed of lifting the heavy object.

[0026] In the embodiment, the power output shaft can directly serve as the power input shaft of the gear transmission assembly when the power output shaft transmits power to the power input shaft of the adjacent gear transmission assembly.

[0027] In the embodiment, the rotating shaft of the winch can be coaxially fixedly connected with the power output main shaft, and the rotating shaft of the winch can directly serve as the power output main shaft.

[0028] In the multi-person operation, each operator can input power through the power input left shaft 5 and the power input right shaft 4 respectively. The left half shaft gear 8 and the right half shaft gear 9 are engaged with the planetary gear 11, so that the planetary gear 11 can rotate along the axial direction and the circumferential direction of the driving gear 10, thereby transmitting power to the power output shaft 6 and the power output main shaft 7, and the rotation of the winch 13 is realized through the engagement of the driven gear 12 and the driving gear 10. The structure design enables multiple operators to apply force synchronously, avoiding the redundancy deficiency and dynamic imbalance risk of single-point driving in the prior art.

[0029] Through the multi-directional force coupling mechanism of the planetary gear 11 differential, the input power of multiple operators can be effectively balanced, and the hoisting rope tension fluctuation caused by asynchronous human input can be avoided, thereby improving the stability and reliability of the system. Therefore, the rescue efficiency and system reliability are significantly improved.

[0030] Through the use of the planetary gear 11 differential, the rescue efficiency can be effectively improved, especially in the multi-person collaborative operation, the load lifting efficiency is significantly improved, the risk of abnormal wear of the gear box is reduced, and the reliability and stability of the system are improved. Compared with the prior art, the planetary gear 11 differential is introduced in the utility model, multi-person combined driving is realized, the collaborative effect of rescue personnel is fully utilized, and the efficiency and safety of the whole rescue operation are improved.

[0031] Through the introduction of multiple power input shafts and the planetary gear 11 differential, the problem of multi-person collaborative operation difficulty caused by the single driving shaft interface in the prior art is solved. Through the design of the planetary gear 11 differential, the power synthesis of multiple power input shafts is realized, which can effectively improve the load lifting efficiency, especially in the case of sufficient rescue personnel, human resources can be fully utilized. In addition, through the design of the power output shaft 6, power can be transmitted to the adjacent gear transmission assembly, multi-point driving is realized, and the stability and reliability of the system are further improved.

[0032] The power output shaft 7 is used for transmitting the power synthesized by the plurality of power input shafts to the winch 13. The planetary gear 11 differential is a key component for realizing power synthesis, including the left half shaft gear 8, the right half shaft gear 9, the driving gear 10 and the planetary gear 11. The power input shafts include the power input left shaft 5 and the power input right shaft 4, and the left half shaft gear 8 and the right half shaft gear 9 are fixedly connected with the corresponding power input left shaft 5 and the power input right shaft 4 respectively. The power output shaft 6 and the power output total shaft 7 are provided with the driven gear 12 meshing with the driving gear 10, and the planetary gear 11 is fixedly arranged on the driving gear 10, and the left half shaft gear 8 and the right half shaft gear 9 mesh with the planetary gear 11 for driving the planetary gear 11 to rotate along the axial direction and the circumferential direction of the driving gear 10.

[0033] Compared with the prior art, the technical scheme introduces the planetary gear 11 differential and the plurality of power input shafts, realizes the collaborative work of multiple people, improves the load lifting efficiency and the stability of the system. In addition, through the design of the power output shaft 6, multi-point driving is realized, which can effectively avoid the problem of instantaneous torque overload of the gear box easily caused by single-point driving in the prior art, and reduces the failure rate of the system.

[0034] The utility model can make multiple rescue workers can simultaneously through respective power input shaft, the planetary gear 11 differential will be synthesized after the power of the power input shaft of the gear transmission assembly, through power output shaft 6 and finally transmit to power output total shaft 7, drive winch 13 rotation. Thus realized the collaborative work of multiple people, improved the load lifting efficiency and the stability of the system. In addition, through the design of the power output shaft 6, multi-point driving is realized, which further improves the reliability of the system, realizes the collaborative work of multiple people, improves the load lifting efficiency and the stability of the system. The planetary gear 11 differential realizes the power synthesis of the plurality of power input shafts through the mutual cooperation of the left half shaft gear 8, the right half shaft gear 9, the driving gear 10 and the planetary gear 11. The power output shaft 6 transmits the synthesized power to the power output total shaft 7 through the driven gear 12 meshing with the driving gear 10, and drives the winch 13 to rotate. Through this design, the problem of instantaneous torque overload of the gear box easily caused by single-point driving in the prior art can be effectively avoided, and the failure rate of the system is reduced.

[0035] The multi-person combined rescue tripod further comprises a shell 2 for carrying the winch 13, the gear transmission assembly and the power output shaft 7, the power input shaft is rotationally arranged in the shell 2, and the shell 2 has a through hole for the winch 13 rope to extend out. The design of the shell 2 plays an important protective and supporting role in the rescue tripod. The shell 2 not only effectively protects the internal winch 13 and gear transmission assembly from the external environment, but also ensures the stable operation of the power output shaft 7 and the power input shaft. By providing a through hole on the shell 2, the winch 13 rope can smoothly extend out and perform rescue operations, improving the structural stability and service life of the entire device.

[0036] A handle 3 is rotationally arranged on the shell 2 and is used to drive the power input shaft. The handle 3 is rotationally arranged on the shell 2 and is used to drive the power input shaft, and the handle 3 is arranged so that the rescuer can rotate the power input shaft through the handle 3, thereby driving the winch 13 to rotate, improving the rescue efficiency.

[0037] The handle 3 can be designed in various ways, for example, it can be designed as an ergonomic grip to make the rescuer more comfortable and labor-saving during operation. The handle 3 can be made of lightweight and strong materials such as aluminum alloy or high-strength plastic to ensure its durability and reliability.

[0038] The handle 3 is slidably arranged along the axial direction of the power input shaft, and further comprises a limiting member for limiting the rotation of the handle 3. The handle 3 is slidably arranged along the axial direction of the power input shaft, which can conveniently store the handle 3 when not in use and quickly adjust it to the appropriate position when in use. By adding the limiting member for limiting the rotation of the handle 3, accidental rotation of the handle 3 during use can be effectively prevented, ensuring the stability and safety of the operation. By adding the axial sliding fit of the handle 3 and the limiting member, the technical problems of inconvenient operation and accidental rotation of the handle 3 in the prior art are solved, improving the operation convenience and safety of the rescue tripod.

[0039] The limiting member is a positioning block 14 arranged on one side of the handle 3 close to the box body, and a positioning groove is formed on the box body, and the positioning block 14 is clamped in the positioning groove to limit the rotation of the handle 3. By setting the cooperation structure of the positioning block 14 and the positioning groove, the rotation of the handle 3 can be effectively limited to ensure that the handle 3 can stably transmit power during operation. Specifically, the positioning block 14 is fixed on the handle 3, and when the handle 3 is slid along the power input shaft to the appropriate position, the positioning block 14 will be clamped into the positioning groove on the box body to prevent the handle 3 from rotating in an unintended state. Thus, the safety and stability of the operation can be improved, and the operation error caused by accidental rotation of the handle 3 can be avoided.

[0040] The structure of the positioning block 14 and the positioning groove can have various implementations. For example, the positioning block 14 can adopt a rectangular, circular or other suitable geometric shape to ensure that it can be stably clamped into the positioning groove. The depth and width of the positioning groove should match the positioning block 14 to ensure the firmness and reliability of the clamping. As a preferred implementation, the positioning block 14 can be fixed on the handle 3 by means of screws or welding, and the positioning groove can be formed on the box body by means of machining or casting.

[0041] The multi-person cooperative rescue tripod further comprises a resilient member for applying a pre-tightening force to the handle 3 in the direction of the shell 2, so that the positioning block 14 can be clamped with the positioning groove. By arranging the resilient member between the handle 3 and the shell 2, the pre-tightening force can be effectively applied to the handle 3, so that the positioning block 14 can be stably clamped in the positioning groove, thereby limiting the rotation of the handle 3. This design not only simplifies the operation process, but also improves the stability and safety of the device. When the operator accidentally separates from the handle 3, the resilient member will drive the handle 3 to slide inward, allowing the positioning block 14 to be clamped with the positioning groove during the rotation of the handle 3, thereby limiting the rotation of the handle 3, improving safety and preventing accidental falling from causing the winch 13 to lose control.

[0042] The bottom foot of the frame body 1 is provided with a ring-shaped protective chain. Specifically, a high-strength metal chain can be arranged around the bottom foot of the frame body 1 to form a closed ring structure. Further, the ring-shaped protective chain can be provided with multiple fixing points to ensure that stress can be evenly distributed when the ring-shaped protective chain is stressed, thereby avoiding stress concentration.

[0043] By arranging the ring-shaped protective chain at the bottom foot of the frame body 1, the technical solution of the present application can significantly improve the stability of the rescue tripod, reduce the risk of loss of dynamic balance control, and thereby improve the rescue efficiency and the reliability of the system. This design effectively solves the technical bottleneck in the prior art, making it possible for multiple people to operate cooperatively, fully utilizing the strength of the rescue personnel and improving the safety and efficiency of the rescue operation.

[0044] In the present embodiment, the frame body 1 adopts a tripod, which comprises a mounting seat and three vertical rods rotatably arranged on the mounting seat. Each vertical rod is formed by a telescopic fixed rod. The shell 2 is mounted on the mounting seat.

[0045] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
