Description

Technical Field

[0001] This utility model relates to the field of earthquake rescue technology, and in particular to a motion performance testing device for earthquake rescue robots. Background Technology

[0002] Earthquake rescue robots play a crucial role in disaster emergency response. Among them, search and location robots can detect signs of life in earthquake-stricken areas and accurately locate trapped individuals; robots carrying communication equipment can establish temporary communication base stations, facilitating collaboration between rescue personnel and other robots, while also providing communication channels between trapped individuals and the outside world; medical support robots can carry first-aid equipment, telemedicine devices, and medicines to quickly provide assistance to the injured. In addition, earthquake rescue robots also include geological exploration robots and robots with independent power supply capabilities.

[0003] The mobility performance of earthquake rescue robots mainly involves climbing and turning. Due to the complex terrain of earthquake-stricken areas, robots require strong mobility to quickly reach target locations and perform tasks in this environment. During missions, robots often need to climb continuous staircases, which frequently have turns, and whose handrails are often damaged by earthquakes. Therefore, thorough testing and training of the climbing and turning performance of earthquake rescue robots is particularly important.

[0004] Utility model patent CN113561224A discloses a device for testing the stability, climbing, and fall prevention performance of a robot. However, this device only covers a single slope and cannot simulate a real continuous staircase environment. It can only be used to test the climbing performance of earthquake rescue robots and cannot be used to test turning performance. In addition, this utility model relies on handrails for protection when the robot's braking fails, which has potential problems such as damage caused by the robot colliding with the handrail, and cannot simulate whether the robot can automatically brake when the handrail is damaged.

[0005] Therefore, there is an urgent need for a device that can simultaneously test the climbing and turning performance of earthquake rescue robots in order to comprehensively test their mobility in earthquake rubble. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned defects of the prior art, thereby providing a motion performance testing device for earthquake rescue robots, comprising: a first platform 1, a second platform 2, an extension platform 3, a first staircase 4, and a second staircase 5; wherein,

[0010] The first side 201 and the second side 202 of the second platform 2 are connected, and the angle between them is 90 to 180 degrees.

[0011] The first side 201 and the third side 203 of the second platform 2 are arranged opposite each other.

[0013] As an improvement to the above-mentioned device, the extension platform 3 is rotatably connected to the third side 203 of the second platform 2 via a hinge. The testing device also includes a limiting member 6 connected to the extension platform 3 for supporting the extension platform 3 so that the extension platform 3 is parallel to the second platform 2 when it is in the first position of the extension platform.

[0014] As an improvement to the above-mentioned device, the limiting member 6 is a telescopic support; the telescopic support is hinged to the extension platform 3; when the extension platform 3 is in the first position of the extension platform, it extends from the bottom of the extension platform 3 to the ground.

[0018] As an improvement to the above-mentioned device, the testing device further includes: a first guardrail 7, wherein,

[0020] A limit hole is provided at one end of the third side 203 of the second platform 2;

[0021] The bottom edge of the first side of the first guardrail 7 extends into the limiting hole;

[0022] The first guardrail 7 rotates between a first position and a second position with its first side as the center of rotation.

[0023] As an improvement to the above-mentioned device, a locking component is provided on the second side of the first guardrail 7 for locking the first guardrail 7 to the first guardrail first position.

[0035] The technical solution provided by this utility model is further illustrated below with reference to the embodiments.

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides a motion performance testing device for an earthquake rescue robot. The device may include: a first platform 1, a second platform 2, an extension platform 3, a first staircase 4, and a second staircase 5.

[0037] The top of the first staircase 4 is connected to the first platform 1, and the bottom is connected to the first side 201 of the second platform 2; the top of the second staircase 5 is connected to the second side 202 of the second platform 2, and the bottom extends to the ground; the extension platform 3 is rotatably connected to the third side 203 of the second platform 2, and has a first position of the extension platform extending outward parallel to the second platform 2 and a second position of the extension platform overlapping the second platform 2; the first side 201 and the second side 202 of the second platform 2 are connected, and the angle between them is 90 to 180 degrees; the first side 201 and the third side 203 of the second platform 2 are arranged opposite each other. Figure 1 The illustration shows a scenario where the angle between the first side 201 and the second side 202 is 90 degrees, meaning the earthquake rescue robot needs to turn 90 degrees when moving from the first staircase 4 to the second staircase 5. However, in other embodiments, the angle between the first side 201 and the second side 202 can be between 90 and 180 degrees. For example, when the angle is 180 degrees, the first side 201 and the second side 202 are in a straight line, and the facing direction of the first staircase 4 is opposite to that of the second staircase 4. In this case, the earthquake rescue robot needs to turn 180 degrees when moving from the first staircase 4 to the second staircase 5.

[0038] The extension platform 3 can be flipped to the third side 203 of the second platform 2 via a 180-degree limiting hinge, so that the extension platform 3 is parallel to the second platform 2 when it is in the first position of the extension platform. Although Figure 1 The 180-degree limiting hinge is not shown, but it is an existing product, and its installation method is a well-known technique to those skilled in the art.

[0039] The extension platform 3 can also be rotatably connected to the third side 203 of the second platform 2 via a hinge that does not limit the angle, and a limiting member 6 connected to the extension platform 3 is provided to support the extension platform 3 so that the extension platform 3 is parallel to the second platform 2 when it is in the first position of the extension platform.

[0040] It is worth noting that the 180-degree limiting hinge can also be used with the limiting component 6, so that when the extension platform 3 is in the first position, it has a stable supporting force sufficient to support the earthquake rescue robot.

[0041] For easy storage, the limiting member 6 can be a telescopic support column; the telescopic support column is hinged to the extension platform 3; when the extension platform 3 is in the first position, it extends from the bottom of the extension platform 3 to the ground. When the extension platform 3 is in the second position, it can be flipped to overlap with the extension platform 3.

[0042] However, in other embodiments, the limiting member 6 can also be a support rod.

[0043] The first staircase 4 includes a plurality of first steps, the plurality of first steps having the same or different heights; the second staircase 5 includes a plurality of second steps, the plurality of second steps having the same or different heights. The heights of the first and second steps are 210mm to 350mm.

[0044] The testing device further includes a first guardrail 7. The first guardrail 7 is positioned above the second platform 2, having a first guardrail position overlapping the third side 203 of the second platform 2 and a second guardrail position avoiding the second platform 2 and the extended platform 3; a limiting hole is provided at one end of the third side 203 of the second platform 2; the bottom end of the first side of the first guardrail 7 extends into the limiting hole; the first guardrail 7 rotates between the first guardrail position and the first guardrail position with its first side as the rotation center. A locking component is provided on the second side of the first guardrail 7 for locking the first guardrail 7 to the first guardrail position. During testing of the earthquake rescue robot, the first guardrail 7 is in the second position, i.e., the open position. After testing, the first guardrail 7 is in the first position, i.e., the closed position, and locked by the locking component. This avoids the risk of operators falling from the third side 203.

[0045] The testing device further includes four second guardrails 8, which are respectively fixed to both sides of the first staircase 4 and the second staircase 5. The extension platform 3, except for the edges of the first side 201, the second side 202, and the third side 203, is fixedly connected to the guardrails. These guardrails prevent the robot from falling from its designated position and also prevent the operator from falling.

[0046] Before the earthquake rescue robot undergoes climbing and turning tests, the operator can open the first guardrail 7, flip the extension platform 3 to the first position, and make the telescopic pole perpendicular to the bottom surface.

[0047] During climbing and turning tests, the earthquake rescue robot started from the first platform 1, first traversed the first staircase 4, then entered the second platform 2, turned, and climbed to the ground via the second staircase 5. If the earthquake rescue robot failed to brake, decelerate, or turn, its trajectory during the turn might exceed the second platform 2. In this case, the extension platform 3 increased the area where the earthquake rescue robot could move, preventing it from falling and protecting both the robot and the personnel on site.

[0048] As can be seen from the above description, the motion performance testing device for earthquake rescue robots provided by this utility model can simultaneously test the climbing and turning performance of earthquake rescue robots, and prevent earthquake rescue robots from falling off the second platform 2 by extending the platform 3.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
