Detailed Description

The utility model provides a roller components mechanism for water drilling machine lift body, includes the lifting body 1 and takes tooth side pipe 2, take tooth side pipe 2 slip cover to establish in the lifting body 1, take the outside of tooth side pipe 2's both ends all stretch out the lifting body 1, take outer wall one side of tooth side pipe 2 to be provided with rack 2-1 along its length direction, install the gear train of being connected with rack 2-1 meshing in the lifting body 1, drive lifting body 1 when the gear train rotates and do elevating movement along taking tooth side pipe 2, the gear train is connected with the drive arrangement that the driving gear rotated usefulness, lifting body 1 in install roller components mechanism, when lifting body 1 is elevating movement along taking

tooth side pipe

2, 3 rolls from top to bottom along the outer wall of taking tooth side pipe 2 of roller components mechanism's gyro wheel.

The roller component mechanism comprises a roller half shaft 4, an outer section of the roller half shaft 4 is fixed on the lifting body 1, an inner section of the roller half shaft 4 extends into the lifting body 1, the roller 3 is rotatably installed on the inner section of the roller half shaft 4, and the outer wheel wall of the roller 3 is in contact with the outer wall of the square pipe 2 with teeth and can roll up and down along the outer wall of the square pipe 2 with teeth.

As shown in fig. 1, 2 and 3, in the scheme of the application, a roller assembly mechanism is adopted, sliding friction is changed into rolling friction, when the lifting body 1 lifts up and down along the square pipe 2 with teeth, the outer wheel wall of the roller 3 is contacted with the outer wall of the square pipe 2 with teeth, and the roller 3 rolls up and down along the outer wall of the square pipe 2 with teeth.
