Embodiment Construction
[0029] Combine below Figure 1 to Figure 6 The technical solution provided by the present invention is described in more detail.
[0030] This embodiment provides a railway work tool including a locking device, a fixing part 3 and a part to be locked 4 , and the locking device includes a clamping part 1 and a driving part 2 . The clamping part 1 is rotatably connected to the fixing part 3 and carried by the fixing part 3 , and the driving part 2 is drivingly connected to the clamping part 1 . Wherein, the driving part 2 can drive the clamping part 1 to switch between the working position and the non-working position; when the clamping part 1 is in the working position, the clamping part 1 can clamp the component 4 to be locked. When the clamping part 1 is in the non-working position, the clamping part 1 is separated from the component to be locked 4 .
[0031] When in use, the locking device is installed on the fixing part 3 , and the clamping part 1 of the locking device is...

The invention discloses a railway operation machine tool and railway maintenance equipment, relates to the field of railway maintenance equipment and is used for ensuring the stable reliability of theequipment after the leveling of the railway operation machine tool. The railway operation machine tool comprises a locking device, a fixing component and a to-be-locked component. The locking devicecomprises a clamping portion and a driving portion. The clamping portion and the fixing component are rotatably connected and are carried by the fixing component. The driving portion and the clampingportion are in driving connection. The driving portion can drive the clamping portion to switch between a working position and a non-working position, when the clamping portion is in the working position, the clamping portion can clamp the to-be-locked component; and when the clamping portion is in the non-working position, the clamping portion and the to-be-locked component are separated. By adopting the technical solution, the clamping portion is arranged on the fixing component, the stress of the clamping portion is finally transmitted to the fixing component, and the load borne by the clamping portion per se is limited, so that the performance reliability can be effectively maintained.
Description
technical field [0001] The invention relates to the field of railway maintenance equipment, in particular to a railway working tool and railway maintenance equipment. Background technique [0002] The railway maintenance vehicle is a special maintenance equipment for railways. The multi-functional operating tools are installed on the maintenance vehicle, which can realize the setting-out, detection and maintenance operations of the catenary. At the corner of the railway, there will be a height difference between the two rails (the outer rail superelevation can reach up to 180mm), and the maximum slope of the locomotive can reach ±8°. In order to ensure that the working surface of the machine tool remains level, a leveling mechanism will be installed at the connection part of the machine tool and the locomotive. When the maintenance vehicle is running, in order to prevent accidental tipping of the equipment, it is necessary to design safe railway operation equipment. [000...
