Chinese patent CN202680386 discloses a railway locomotive limit detection device, the detection device is fixed, and the replacement and adjustment of the limit gauge is inconvenient
[0006] Chinese patent application CN105438219A discloses a simple limit gauge for railway locomotives. The detection device as a whole is a limit detection tool. The size of the device is large, and it can only be applied to a certain model. It has a single function and is inconvenient to use.
[0007] Chinese patent CN204264182U discloses a rolling stock limit detection device. The detection device uses the limit size of a certain type of rolling stock as a sample, and the sample is fixed on the supporting frame. The overall structure is simple, inconvenient to use, and cannot be adjusted.

Embodiment Construction

[0048] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0049] A rail vehicle limit detection device, such as figure 1 As shown, it includes the main components such as the lifting mechanism, the mechanical self-connecting mechanism and the limit gauge 3. Wherein the lifting device comprises: a gantry frame 1, a driving device 2, a wire rope 7, a pulley 6, a guide rail 4, and a movable frame 5. The mechanical self-connecting hanging mechanism includes: lower hook plate 8, reset plate 9, upper hook plate 10, ...

Abstract

The invention discloses a railway vehicle clearance detection device and a detection method. The clearance detection device comprises a gantry frame and a moving bracket used for installing a clearance gauge. The moving frame can be driven by a driving device to do reciprocating motion along the height direction of the gantry frame. A self-coupling mechanism used for locking the moving bracket on the top of the gantry frame and a reset element used for releasing the lock are arranged between the top of the gantry frame and the moving bracket. The clearance gauge can be replaced conveniently and quickly during clearance measurement of different models of locomotives vehicles. After clearance measurement, the clearance gauge can be lifted up and reliably coupled by a mechanical device. When the device is used next time, the clearance gauge can be loosened automatically.

Description

technical field [0001] The invention relates to a rail vehicle limit detection device and a detection method, belonging to the field of rail vehicle limit detection. Background technique [0002] In the production process of rail vehicles, it is necessary to measure and verify the outline dimensions of rail vehicles to ensure that the dimensions of the vehicles meet the national standards and the requirements of the contracting party, and to prevent rail vehicles from colliding with the surrounding area when passing bridges, tunnels or curves. equipment collision interference. [0003] Due to the limitation of production conditions, the production line used for limit inspection is usually used to store or debug various types of rolling stock. Therefore, after the limit detection is completed, the limit gauge needs to be raised and fixed to facilitate other types of rolling stock. Pass or deposit. [0004] At present, the top beam of the mechanical limit detection device us...
