Description

Technical Field

[0001] The invention belongs to the technical field of through-tunnel rain test, and in particular relates to a through-tunnel rain test device. Background Art

[0002] Gangway showering is an essential step in the overall inspection process after gangway assembly. It determines critical quality issues such as leaks and sealing. Low-floor gangways, such as those in Huangshi and Huangpu, have large exterior dimensions and high traffic volume, making proper showering impossible with existing carriages. However, this is a necessary test. The typical showering process involves an overhead crane hoisting the gangway onto a pallet at the entrance, covering the end face, and then transporting it to the shower room by forklift, which is very inconvenient. Furthermore, the customer required a specific distance between the sprinkler head and the gangway. The existing system uses a screw-driven mechanism, which rusts and becomes immobile due to long-term exposure to rain and fog. This often results in the distance from the sprinkler head to the end face failing to meet the test requirements, severely impacting test results. In particular, various data requirements cannot be met during review. Furthermore, the gangway carriages are manually moved by pushing and pulling. As the shower platform weighs nearly 0.5 tons, it is laborious for one person to push it, resulting in uneven force distribution and frequent jamming.

[0003] Therefore, there is an urgent need for a through-channel rain test device that is easy to adjust the spray stroke and easy to move to solve the problems existing in the prior art. Summary of the Invention

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] Example:

[0030] refer to Figure 1A through-passage rain test device includes a test frame 1, a test bench 2, a carrying trolley 3 and a spray assembly 4; the test bench 2 is arranged below the test frame 1 and is used to place the through-passage 6 to be tested; the carrying trolley 3 is movably arranged on a track 4.31 below the test frame 1 and is detachably connected to the test bench 2, and the carrying trolley 3 is provided with a compartment 5 connected to the through-passage 6 to be tested; the spray assembly 4 is movably arranged on the test frame 1 and is used to spray the compartment 5 and the through-passage 6 below.

[0031] The movable spray assembly makes it easy to adjust the spray stroke, and the carrying trolley makes it easy to move the carriage. The above-mentioned coordinated settings make the distance from the nozzle to the end face adjustable to meet the test requirements and improve the test effect. The movement of the carriage in the through-channel helps to reduce the manual burden, and the force is more evenly distributed, which makes it less likely to get stuck.

[0032] refer to Figure 1 and Figure 3 , the spray assembly 4 includes a top spray head 4.1, a side spray head 4.2 and a moving assembly 4.3;

[0033] The top sprinkler head 4.1 is fixedly arranged on the top of the test frame 1; the movable component 4.3 is movably arranged on the top of the test frame 1, and the side sprinkler heads 4.2 are arranged on both sides of the through channel 6 through the movable component 4.3, and the side sprinkler heads 4.2 are adjusted in distance from the sides of the through channel 6 through the movable component 4.3.

[0034] The sprinkler head is set on the top of the test frame through a movable assembly, which is conducive to uniform spraying on the one hand and avoids interference with the carrying trolley on the other hand.

[0035] The moving assembly 4.3 includes a track 4.31 and a flatbed trolley 4.32; the track 4.31 is arranged on both sides of the top of the test frame 1, the flatbed trolley 4.32 is slidably arranged on the track 4.31 through bearings 4.34, and the side sprinkler head 4.2 is arranged on the flatbed trolley 4.32.

[0036] The upper part is set as a flatbed trolley. In order to ensure the stability of operation, four pairs of bearing rollers are provided. Each pair has one track bearing responsible for movement, and the other is responsible for preventing the rain nozzle from tipping over during movement. It is a buckle bearing. The buckle bearing is used in conjunction with the anti-roll bar. The anti-roll bar limits the position of the buckle bearing to avoid tipping over. The track bearing is used in conjunction with the track, which ensures both stable operation and anti-tipover.

[0037] The moving assembly 4.3 also includes a cylinder mounted on the test stand 1. This cylinder is connected to a flatbed trolley 4.32 and is used to propel the trolley 4.32 along the track 4.31. Once the gangway reaches its desired position, the sprinkler heads on both sides are adjusted. The cylinder is used as the power mechanism, avoiding issues such as water resistance and rust associated with conventional electric screws.

[0038] The moving assembly 4.3 further includes an anti-roll bar 4.33, which is arranged above the track 4.31 and parallel to the track 4.31, and is used to prevent the flatbed trolley 4.32 from overturning on the track 4.31.

[0039] The bearings 4.34 include track bearings and buckle bearings arranged in parallel. The track bearings are used for the flatbed trolley 4.32 to move along the track 4.31, and the buckle bearings are used to support the anti-roll bar 4.33 and prevent the flatbed trolley 4.32 from overturning on the track 4.31.

[0040] refer to Figure 2 The carrier trolley 3 is also equipped with a power assembly 3.1, which includes a drive motor 3.11, a planetary reducer 3.12, a steering box 3.13, a connecting rod 3.14, and a drive wheel 3.15. The drive motor 3.11 and the planetary reducer 3.12 are mounted on the frame 3.16 of the carrier trolley 3 via a connector 3.17. The drive motor 3.11, the planetary reducer 3.12, and the steering box 3.13 are sequentially connected in a transmission manner. The steering box 3.13 is connected to the drive wheels 3.15 on both sides via a connecting rod 3.14. The drive wheels 3.15 are connected to the track 4.31. The steering box 3.13 is an ARA series spiral bevel gear steering box.

[0041] This embodiment adopts the form of drive wheels plus rails, and the drive wheels adopt a dual-wheel synchronous drive mode. Driven by the drive wheels on both sides, it is ensured that the drive wheels of the through-tunnel car can move in and out at the same speed, and ensure that they do not deviate to one side to meet the requirements of simultaneous entry and exit of the through-tunnel and the car.

[0042] The test bench 2 is movably arranged on the rail 4.31 via rollers.

[0043] The ground under the test bench 2 is provided with a slope for following the water.

[0044] In this embodiment, after the car body is connected with the carrying trolley, the gangway is hoisted onto the test bench by an overhead crane and connected to the car body. After moving to the bottom of the test frame, the sprinkler components on both sides need to be adjusted before raining. Through the track added on the top of the rain frame, the sprinkler head can move with the rain spray stroke adjustment component. The cylinder is installed at the bottom, and the distance of the sprinkler head can be manually adjusted by the cylinder. After the distance between the sprinkler head and the gangway is adjusted, raining can be realized. After the raining is completed, the car body is manually controlled to make the entire gangway rained and then transported back to the factory area. The crane is hoisted into the inspection area, making the entire raining platform semi-automated.

[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
