Problems solved by technology
For medium and large cast pipes around DN1000, due to the increase in the diameter of the cast pipe, the head of the pipe pulling forceps becomes large and heavy.
If the oil cylinder and guide column structure are still used, firstly, it will cause serious wear between the guide column and the guide sleeve; secondly, the structure is not coordinated and reasonable

Embodiment Construction
[0009] Such as figure 1 , 2 As shown, the bottom of the box-type trolley 2 is hinged with casters 6, and the casters 6 are seated on the guide rail 4 fixed on the ground. The box-type trolley 2 is fixed, and the other end is hinged with a support 5 fixed on the ground.
[0010] The guide rail 4 is a channel steel wheel guide rail, which can prevent the box type trolley 2 from tipping over when the tube is pulled out.
[0011] The retaining wheel device 7 is fixed on the guide rail 4, which can block the axial movement of the pipe mold.
[0012] The expansion and contraction of the piston rod of oil cylinder 3 drives the car body to advance and retreat.

The invention relates to a tube drawing trolley for a centrifugal machine, wherein the bottom of a box body type trolley is hinged with trundles which are fixed on guiderails on the ground, an expansion device for a tube drawing wrench is fixed at the upper part of the box body type trolley, one end of an oil cylinder is fixed with the box body type trolley, and the other end of the oil cylinder is hinged with a support fixed on the ground.
Description
technical field [0001] The invention relates to a tube extubation vehicle for a centrifuge. Background technique [0002] For the tube-extracting structure of the two-station centrifuge tube-extracting tongs for ductile iron pipes below DN800, one oil cylinder and two horizontal guide columns are used to complete the extraction of the cast tube from the pipe mold. And for medium and large cast pipes around DN1000, due to the increase in cast pipe caliber, the head of the pipe pulling forceps becomes large and heavy. If the structure of the oil cylinder and the guide post is still adopted, firstly it will cause severe wear between the guide post and the guide sleeve; secondly, the structure is not coordinated and reasonable. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides a tube extubation cart for a centrifuge. It runs smoothly, has a reasonable structure and is durable. [0004] The technical solution ad...
