Abstract
The utility model provides a locomotive gear box gland locking device is equipped with a L shape depression bar of constituteing by montant and horizontal pole on gear box one side lateral wall, and the montant welding is on the gear box lateral wall, and the horizontal pole height is higher than the gear box gland, has welded a fixation nut at the horizontal pole end, and the fixation nut in-connection has the lock bolt, and the lock bolt lower extreme has at least one roof pressure nut, and the roof pressure nut bottom surface of bottom compresses tightly on the gear box gland. The utility model discloses can effectively alleviate the vibrations harm that the locomotive operation in-process striking caused, reduce gear box screw thread wearing and tearing, prevent that the gland from droing, reduce spare part consumption and maintenance work volume, avoid the locomotive derailment accident.
Description
Technical Field
The utility model belongs to the railway vehicle equipment field especially relates to a simple and easy locking device for locomotive gear box gland.
Background
The traveling gearbox of the electric locomotive in the transport operation area ZG46T of the saddle steel share chemical industry department is made of a 10mm thick steel plate, a box body of the gearbox is provided with screw threads, a gland of the gearbox is provided with inner screw threads, and the gland and the box body are connected in a threaded manner and are fastened and sealed by bolts. Because the running time is long, and in addition, the impact in the running process of the locomotive causes the screw thread of the box body of the gear box to be worn, the fastening effect cannot be realized, the phenomenon that the gland of the gear box falls off frequently occurs, the spare part consumption and the maintenance workload are increased, and the locomotive derailment accident is very easy to cause if the gland falls off a rail.
Disclosure of Invention
The utility model aims at providing a prevent that the gland from droing, reduce spare part consumption and maintenance work volume, avoid locomotive derailment accident's locomotive gear box gland locking device.
Therefore, the utility model discloses the technical solution who takes does:
a locomotive gear box gland locking device comprises a pressure rod, a fixing nut, a locking bolt and a jacking nut; the side wall of one side of the gear box is provided with an L-shaped pressure rod consisting of a vertical rod and a horizontal rod, the vertical rod is welded on the side wall of the gear box, the horizontal rod is higher than the gear box pressing cover, a fixing nut is welded at the end of the horizontal rod, a locking bolt is connected in the fixing nut, the lower end of the locking bolt is provided with at least one jacking nut, and the bottom surface of the jacking nut at the lowest end is tightly pressed on the gear box pressing cover.
The cross rod is higher than the gear box gland by more than 50 mm.
The utility model has the advantages that:
the utility model discloses compress tightly the gland on the gear box, can effectively alleviate the vibrations harm that the striking caused in the locomotive operation process, reduce gear box screw thread wearing and tearing to prevent that the gland from droing, reduce spare part consumption and maintenance work volume, avoid the locomotive derailment accident.
Drawings
Fig. 1 is a schematic perspective view of a locking device for a gland of a gearbox of a motorcycle.
In the figure: the gear box comprises a gear box 1, a vertical rod 2, a gland 3, a cross rod 4, a fixing nut 5, a locking bolt 6 and a jacking nut 7.
Detailed Description
As shown in the attached figure 1, the locking device for the locomotive gearbox gland of the utility model consists of a pressure rod, a gland 3, a fixing nut 5, a locking bolt 6 and a jacking nut 7; the compression bar is L-shaped and consists of an integrated vertical bar 2 and a cross bar 4. The left front side wall of the gear box 1 is additionally provided with a locking device, wherein a vertical rod 2 of a pressure rod is welded on the left front side wall of the gear box 1, the height of a cross rod 4 is 60mm higher than that of a gland 3, a fixing nut 5 is welded at the end of the cross rod 4, a locking bolt 6 with the length of 100mm is connected in the fixing nut 5, the lower end of the locking bolt 6 is provided with a jacking nut 7, the bottom surface of the jacking nut 7 is tightly pressed on the gland 3 of the gear box 1, and the gland 3 is tightly pressed and locked on a box body of the gear box 1. The specifications of the internal threads of the fixing nut 5 and the jacking nut 7 and the external threads of the locking bolt 6 are all phi 10 mm.
