Description

Axle gear box fixing device for two-axle locomotive to fall

Technical Field

The utility model belongs to the track traffic field for shunting operation and track laying operation, concretely relates to diaxon locomotive falls automobile-used axletree gear box fixing device.

Background

The existing locomotive is generally provided with a bogie, the bogie is two shafts or three shafts, and an axle gear box is fixed by a draw arm and a third universal shaft on the bogie and cannot rotate and incline around an axle when the locomotive falls off, so that the bogie can be directly placed on a track at a certain interval and then the locomotive falls off, but the bogie is expensive in manufacturing cost and is not suitable for all locomotives; therefore, a two-axle locomotive still exists, namely a pair of wheel set driving devices are respectively arranged at the front and the rear of the lower part of the locomotive, namely the locomotive has no bogie, so that a universal shaft and a pull arm seat of the locomotive are both arranged at the lower part of a locomotive body, and an axle gear box on a single wheel set cannot keep balance when the locomotive falls down, and cannot keep level due to the action of gravity and can rotate around the axle so as to ensure accurate falling and butt joint of the universal shaft. It is therefore necessary to fix the axle gear box when the vehicle is dropped. However, the bottom shapes and heights of different axle gear boxes are different, so that the common fixing device is difficult to meet the fixed requirements of the axle gear boxes.

Disclosure of Invention

The utility model provides a technical problem be: a fixing device capable of being adjusted in multiple directions is provided, so that the mounting requirements of all axle gear boxes can be met.

The utility model adopts the technical scheme as follows:

an axle gear box fixing device for two-axle locomotive falling comprises a base and a plurality of sliding grooves formed in the base, wherein the sliding grooves are distributed uniformly in a divergent mode on the center of the base, at least three sliding grooves are provided with slidable sliding screw rods, fixing structures are arranged on the sliding screw rods and used for fixing the sliding of the sliding screw rods, and the sliding screw rods are in threaded connection with an upper threaded sleeve.

Preferably, the sliding groove is a T-shaped groove, and the sliding screw is a T-shaped sliding screw.

Preferably, the base is cylindrical.

Preferably, the fixing structure is a locking plate, and a threaded hole matched with the thread of the sliding screw is formed in the center of the locking plate.

Preferably, the upper threaded sleeve is a threaded sleeve which is connected with each other and internally provided with threads, and a top support surface arranged at the top of the threaded sleeve.

Preferably, the top bracing surface is cylindrical.

Preferably, the threaded sleeve and the top bracing surface are integrally formed.

Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

Example 1

An axle gear box fixing device for two-axle locomotive falling is shown in figures 1-4 and comprises a base 1 and a plurality of sliding grooves 2 arranged on the base, wherein the sliding grooves 2 are distributed uniformly in a divergent mode in the center of the base 1, at least three sliding grooves 2 are provided with slidable sliding screw rods 3, fixing structures 5 are arranged on the sliding screw rods 3 and used for fixing the sliding of the sliding screw rods 3, and the sliding screw rods 3 are in threaded connection with upper threaded sleeves 4. The utility model discloses an axle gear box fixing device for two-axle locomotive to fall off, including base 1, is used for placing on the ground, is provided with a plurality of spouts 2 on base 1, and a plurality of spouts 2 are with base 1 center form divergence form evenly distributed, explain that spout 2 on base 1 distributes in different position, and have at least three spout 2 is provided with slidable sliding screw 3, sliding screw 3 is provided with fixed knot structure 5 for the slip of fixed sliding screw 3, sliding screw 3 and last swivel nut 4 threaded connection, this is because according to the bottom shape and the height difference of different axle gear boxes, the strong point that needs to set up on base 1 is different, need 3 strong points at minimum to guarantee that the axle gear box does not rotate, therefore, have at least three spouts 2 to be provided with slidable sliding screw 3, according to actual conditions, need several strong points, namely, sliding screw rods 3 are arranged on the corresponding sliding chutes 2; meanwhile, the sliding screw 3 can slide on the sliding chute 2, so that the gear box can be fixed by selecting the most suitable fixing point, the sliding of the sliding screw 3 is stopped at the most suitable point, and the sliding screw 3 is fixed by the fixing structure 5, however, the heights of the axle gear boxes can be different, so that the upper threaded sleeve 4 can be screwed out to the fixing surface of the fixed gear box by screwing the upper threaded sleeve 4 in threaded connection with the sliding screw 3 out, and the function of supporting and fixing the gear box is achieved. When the car falls, the main weight of axletree gear box is born by axletree and wheel pair, consequently fixing device only need carry on a little atress support can, consequently the utility model discloses with slide sleeve 4 on a plurality of revolve out the stationary plane of top at the gear box from sliding screw 3, can play and support fixed gear box to the problem that the axletree gear box overturns around the axletree when making the diaxon locomotive fall makes the convenient operation of falling. And the axle gear box fixing device meets the fixing requirements of all axle gear boxes by the movement of the sliding screw 3 on the base 1 and the up-down movement of the upper threaded sleeve 4 above the sliding screw 3.

Example 2
