Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary legs of rescue equipment, and in particular to a leg of modular rescue equipment and rescue equipment using the leg. Background Art

[0002] Rescue equipment is mainly used to replace rescuers to enter disaster sites with complex terrain to complete tasks such as environmental monitoring and life search. According to different movement forms and functions, it can be divided into tracked rescue equipment, wheeled rescue equipment, and bionic rescue equipment. Tracked rescue equipment has the advantages of large support area and good movement performance on rough roads. It is one of the most widely used movement methods for rescue equipment.

[0003] The current problem is that no matter it is a tracked rescue equipment or a wheeled rescue equipment, its ability to climb a steep slope (at least 40°) and stay on a slope is relatively poor. To improve the climbing and staying on a slope ability, the method currently commonly used is to install outriggers on the front and rear sides of the equipment. However, the movement trajectory of the existing outriggers is an arc, which is prone to soil digging, especially in soil with high humidity. This situation is more obvious, and this working condition will be accompanied by soil accumulation. Therefore, its climbing and staying on a slope ability will be relatively greatly reduced. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a support leg of modular rescue equipment and rescue equipment using the support leg, so as to improve the climbing and staying ability of the rescue equipment.

[0008] Furthermore, the free ends of the pitch cylinder, the upper connecting outer rod, the lower connecting outer rod and the translation cylinder are all hingedly provided with hinged mounting seats.

[0009] Furthermore, the pitch cylinder and the translation cylinder are oil cylinders or air cylinders.

[0010] Furthermore, the upper connecting outer rod and the upper connecting inner rod, the lower connecting outer rod and the lower connecting inner rod, and the adjusting inner rod and the adjusting outer rod are all sealed and slidably sleeved.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-2 As shown, the legs of the modular rescue equipment of this embodiment include an upper connecting arm, a lower connecting arm, an adjusting connecting rod, a translation cylinder 3, an L-shaped connecting rod 7 formed by integrally forming a vertical rod body and a horizontal rod body, a foot-type hoe stopping mechanism 8 and a pitch cylinder 13; the upper connecting arm and the lower connecting arm are arranged vertically and parallel, the upper connecting arm includes a sliding sleeve upper connecting outer rod 2 and an upper connecting inner rod 11, the lower connecting arm includes a sliding sleeve lower connecting outer rod 4 and a lower connecting inner rod 6, the adjusting connecting rod includes a sliding sleeve adjusting inner rod 9 and an adjusting outer rod 10; the free ends of the upper connecting inner rod 11 and the lower connecting inner rod 6 They are respectively hinged to the upper and lower ends of the side wall of one side of the vertical rod body, the free end of the adjusting outer rod 10 is hinged to the upper end of the side wall of the other side of the vertical rod body, and the free ends of the adjusting inner rod 9 and the horizontal rod body are both hinged to the foot-type hoe stopping mechanism 8; the cylinder barrel of the pitch cylinder 13 is hinged to the upper connecting outer rod, and the upper connecting outer rod 2 and the lower connecting outer rod 4 are connected across with an intermediate connecting rod 5. Specifically, the two ends of the intermediate connecting rod 5 are respectively connected to the side walls of the upper connecting outer rod 2 and the lower connecting outer rod 4 through connecting ears 12; the intermediate connecting rod 5 ensures the consistency of the movements of the upper connecting outer rod 2 and the lower connecting outer rod 4. The piston rod of the translation cylinder 3 is hinged to the L-shaped connecting rod. Specifically, the cylinder barrel of the pitch cylinder 13 is hinged to the upper connecting outer rod 2 through a hinge seat, the upper connecting inner rod 11, the piston rod of the translation cylinder 3 and the lower connecting inner rod 6 are all hinged to one side wall of the vertical rod body through a hinge seat, the free end of the adjusting outer rod 10 is hinged to the other side wall of the vertical rod body through a pin shaft, and the free ends of the adjusting inner rod 9 and the horizontal rod body are both hinged to the foot-type hoe stopping mechanism 8 through a hinge seat.

[0021] The free ends of the pitch cylinder 13, the upper connecting outer rod 2, the lower connecting outer rod 4 and the translation cylinder 3 are all hingedly provided with an articulated mounting seat 1; the pitch cylinder 13 and the translation cylinder 3 are oil cylinders or air cylinders, and the oil cylinder is selected in this embodiment; the upper connecting outer rod 2 and the upper connecting inner rod 11, the lower connecting outer rod 4 and the lower connecting inner rod 6, and the adjusting inner rod 9 and the adjusting outer rod 10 are all sealed and slidably sleeved to avoid the sliding pair from being stuck due to sand and stones.

[0022] like Figure 3As shown, this embodiment also discloses a rescue equipment. Specifically, legs are provided on the front and rear sides of the rescue equipment body 14. The front and rear legs are respectively connected to the front and rear sides of the body through hinged mounting seats.

[0023] When climbing a slope, the front outrigger is lowered and its foot-type hoe mechanism is inserted into the ground, and then the front translation cylinder is retracted; at the same time, the rear outrigger is lowered to the slope in the same way and its foot-type hoe mechanism is inserted into the slope, and the rear outrigger is extended outward. The whole machine uses the pulling force of the front outrigger and the supporting force of the rear outrigger to assist the crawler to climb the slope. This reciprocating cycle can enable the platform to climb steep slopes in a walking-foot working form.

[0024] The foot-type hoe stopping mechanism of this embodiment has a parallel four-bar linkage formed between the adjusting connecting rod and the L-shaped connecting rod, and a parallel four-bar linkage formed between the vehicle body, the upper connecting arm, the lower connecting arm and the vertical rod body of the L-shaped connecting rod. The two sets of parallel four-bar linkages ensure the stability of the foot-type hoe stopping mechanism 8 at any time. During operation, through the coordinated action of the pitch cylinder 13 and the translation cylinder 4, the supporting legs are lowered as a whole, and the foot-type hoe stopping mechanism is gradually inserted into the ground, or the supporting legs are lifted as a whole, so that the foot-type hoe stopping mechanism is pulled out in a direction perpendicular to the ground, so as to perform the next hoe stopping movement. The whole process avoids the "digging soil" phenomenon and greatly improves the climbing and staying ability of the rescue assembly. Thereby, the "digging soil" phenomenon can be avoided.

[0025] Compared with other rescue equipment, modular rescue equipment equipped with this highly mobile obstacle-crossing mechanism has better adaptability to working conditions, can cope with steep slopes well, and can stay on the slope. The entire mechanism adopts hydraulic transmission, which can output greater torque than other transmission methods, and achieve low-speed and large-tonnage propulsion. At the same time, under the same power conditions, the hydraulic transmission device is small in size, light in weight, and compact in structure. Hydraulic components can be connected by pipes or integrated connections, and their layout and installation are very flexible.

[0026] In addition, the legs are of assembled design to facilitate disassembly and transportation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
