[0002] The connecting passageway is a crucial component commonly found in rail vehicles, used to connect two adjacent carriages, facilitating passenger passage and providing a sense of safety and comfort. During rail vehicle operation, the connecting passageway undergoes movement along six axes: lateral, longitudinal, vertical, rotational, roll, and nodding. It must also meet the requirements for navigating curves. To verify whether the connecting passageway meets relevant standards and customer technical specifications in these six axes, and to validate its durability after numerous operational cycles, a connecting passageway testing device is essential. Existing testing devices cannot meet these requirements. For example, Chinese Patent 201110028509.3 discloses a windshield testing device for high-speed trains, which has a left frame and a right frame. The end walls of the left and right frames are equipped with positioning seats for positioning the windshield. The end walls of the left and right frames are equipped with locking plates that cooperate with the locking hooks of the windshield for locking. The end walls of the left and right frames are provided with U-shaped cavities that can be squeezed with the rubber sealing strip of the windshield to form a sealed space. An entrance and exit gate is opened on the end wall of the left or right frame. The entrance and exit gate is equipped with a sealing ring and a clamping bolt for pressing the entrance and exit gate. The left and right frames are equipped with limit rods. The bottom of the left and right frames is equipped with lockable wheels.

Chinese Patent 202410918939.X discloses a windshield load-bearing capacity testing device, comprising: a test fixture, the test fixture including a frame-shaped fixture plate that fixes the windshield to its inner periphery; a plurality of actuators, one end of each actuator being fixed and the other end being directly or indirectly connected to at least one loading point on the outer side of the fixture plate; and a strain sensor, the strain sensor being installed on the windshield, the windshield fixed to the fixture plate and the test fixture forming a chamber, the windshield load-bearing capacity testing device also having a pressure regulating device to regulate the pressure inside the chamber, the windshield fixed to the fixture plate and the test fixture forming a chamber, the windshield load-bearing capacity testing device also having an internal temperature regulating device to regulate the temperature inside the chamber, at least one actuator being connected to the plurality of loading points via a lever mechanism, the strain sensor being a strain gauge, the windshield including a windshield body and a windshield plate disposed on the outer periphery of the windshield body, the windshield being fixed to the inner periphery of the fixture plate at the windshield plate by fasteners. Therefore, it is necessary to develop and design a through-passage testing device that meets the requirements for six-axis detection of the through-passage's lateral displacement, longitudinal displacement, vertical displacement, rotation angle, roll angle, and nodding angle. At the same time, it is also necessary to meet the requirements for detecting the through-passage's limit displacement and limit angle in the above six axes and for motion durability testing.

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a through-passage testing device to test the function of the through-passage, ensure that the through-passage meets the requirements of relevant standards and customer technical specifications, and guarantee the safety and comfort of rail vehicles.

[0004] To achieve the above objectives, the main structure of the through-channel test device of this utility model includes a left mounting base and a right mounting base that are independently arranged, and a transverse frame, a triangular frame and a vertical frame arranged in sequence on the left mounting base, and a side rolling frame, a nodding frame and a rotating frame arranged in sequence on the right mounting base.

[0005] The left mounting base is connected to the horizontal frame, the horizontal frame to the triangular frame, and the triangular frame to the vertical frame, respectively, via corresponding linear guides and lead screws.

[0006] The right mounting base is connected to the side rolling frame, the side rolling frame is connected to the nodding frame, and the nodding frame is connected to the rotating frame via corresponding linear push rods and bearings.

[0007] When using the through-passage testing device of this utility model, after connecting it to an external industrial control computer and servo motor, the left and right halves of the through-passage are respectively installed on the vertical frame and the rotating frame.

[0008] Based on the corresponding linear guide and lead screw:

[0009] The transverse frame drives the passageway to move horizontally.

[0010] The triangular frame drives the passageway to undergo longitudinal compression and lifting movements;

[0011] The vertical frame drives the through passage to move vertically upward and downward;

[0012] Based on the corresponding linear actuator and bearings:

[0013] The side roll frame drives the through channel to perform a horizontal side roll motion;

[0014] The nodding frame drives the passageway to nod.

[0015] The rotating frame drives the through-passage to rotate.

[0016] This enables the control and detection of movement in six axial directions of the through channel: lateral, longitudinal, vertical, rotational, nodding, and side roll.

[0017] Compared with the prior art, this utility model consists of two parts for installing the through-passage. One part has the functions of lateral displacement, longitudinal displacement, and vertical displacement, so that the through-passage can be moved laterally, longitudinally, and vertically. The other part has the functions of rotation, flipping, and head-turning, so that the through-passage can be rotated, flipped, and head-turning. In use, the servo motor is controlled by an external industrial control computer to make the two parts of the through-passage move and rotate in six directions. Its structure is simple, easy to operate, and has the advantages of high detection accuracy and accurate action, which greatly improves the reliability and safety of through-passage testing and is of great significance for the functional testing of through-passages.
