Description

Technical Field

[0001] This utility model belongs to the field of inspection and maintenance technology, specifically relating to a stop protection device for a maintenance ladder of a high-speed train. Background Technology

[0002] Every 90 days, the maintenance team needs to inspect and clean the windshield wipers, windshields, and other equipment at both ends. This inspection, cleaning, and troubleshooting requires the use of a straight ladder longer than 2 meters, necessitating manual safety precautions. Due to the small friction area between the ladder and the track platform slab, and the smooth surface of the slab, the ladder is prone to slipping, potentially causing falls and injuries to personnel. Currently, to ensure safety, additional manual safety measures are typically required, necessitating three people: one working on the ladder and two holding it for safety. This traditional method consumes more labor and increases labor costs. Currently, there is a lack of a stop and safety device for the EMU maintenance ladder to provide effective stopping and limiting, preventing slippage and reducing the risk of falls for personnel.

[0003] Therefore, a new technology is needed to address the lack of a stop and protection device for maintenance ladders on high-speed trains in the existing technology. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a stop and protection device for a maintenance ladder on a high-speed train. This device can provide an effective stop and limit for the ladder, preventing it from slipping and reducing the risk of people falling off the ladder.

[0005] The present invention adopts the following technical solution:

[0006] A stop protection device for a maintenance ladder for high-speed trains includes a stop body and several stop limiting bodies; a first hook is provided at the first end of the stop body, which is used to hang on a ramp; several limit bodies are provided on the stop body, and a set distance between adjacent limit bodies is maintained; the limit bodies are used to restrict the movement of the ladder.

[0007] Furthermore, the main body of the stop is a steel plate structure.

[0008] Furthermore, the thickness of the stop body is 2mm to 4mm.

[0009] Furthermore, the first hook body is a hook body made of steel plate, and the first hook body and the stop body are an integrated structure.

[0010] Furthermore, the first hook body includes a first steel plate and a second steel plate; the first steel plate is connected to the flat plate of the stop body at a first predetermined angle; the second steel plate is connected to the first steel plate at a second predetermined angle.

[0011] Furthermore, the limiting body has two positions; the second end of the stop body has the first-position limiting body; the second-position limiting body maintains a set position distance from the first-position limiting body and is disposed on the stop body.

[0012] Furthermore, the limiting body of the first stage and the stop body are an integrated structure; the limiting body of the second stage is welded to the stop body.

[0013] Furthermore, the limiting body of the first stage is a third steel plate; the third steel plate is connected to the flat plate of the stop body at a third predetermined angle.

[0014] Furthermore, it also includes a second hook body, which is provided on the third steel plate. The second hook body includes a fourth steel plate and a fifth steel plate. The fourth steel plate is connected to the third steel plate at a fourth predetermined angle, and the fifth steel plate is connected to the fourth steel plate at a fifth predetermined angle.

[0015] Furthermore, it also includes stiffening ribs; the first-stage limiting body is reinforcedly connected to the flat plate of the stop body through the stiffening ribs; the second-stage limiting body is reinforcedly connected to the flat plate of the stop body through the stiffening ribs.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model discloses a stop protection device for a maintenance ladder on a high-speed train, comprising a stop body and several stop limiting bodies. The first end of the stop body is provided with a first hook, which can be hooked onto the track platform slab to restrict the movement of the stop body. The stop body is provided with several stop limiting bodies, and adjacent limit bodies maintain a set distance between them. These limit bodies restrict the movement of the bottom of the ladder. During operation, the bottom of the ladder (maintenance ladder) can abut against the limit bodies at different positions, adjusting the ladder's contact angle and height, effectively improving the flexibility of spatial operations. Simultaneously, due to the limiting effect of the limit bodies, the bottom of the ladder is less likely to move after contact, thus improving operational safety. Previously, before this utility model, three people were required for the operation; with this utility model, this can be reduced to two people. For example, with the stop protection device limiting the bottom of the ladder, one person works on the ladder while the other holds it, allowing for smooth inspection, cleaning, and troubleshooting work. This utility model reduces labor costs.

[0018] This utility model discloses a stop and protection device for a maintenance ladder for high-speed trains. It can provide an effective stop and limit for the ladder, preventing the ladder from slipping and reducing the risk of people falling off the ladder. Attached Figure Description
