Abstract
The present invention relates to a mobile pipe lining apparatus for installing strip lining material into a host pipe. The apparatus comprises a lining machine for receiving a feed of strip lining material and placing it in a host pipe to form a new pipe lining, a carriage attached to the lining machine such that the full weight of the lining machine is borne by the carriage, and adjusting means for adjusting a position of the lining machine relative to the carriage.
Claims18
A mobile pipe lining apparatus for installing strip lining material into a host pipe, comprising:
- a lining machine for receiving a feed of strip lining material and placing it in a host pipe to form a new pipe lining;
- a carriage attached to the lining machine such that at least a portion of the weight of the lining machine is borne by the carriage;
- and
- adjusting means for adjusting a position of the lining machine relative to the carriage,
- wherein the adjusting means comprises:
- a joint arranged between the carriage and the lining machine, and
- adjustable stabilizers, each adjustable stabilizer comprising a bar extending between the carriage and the lining machine;
- and
- wherein the carriage comprises:
- a weight holder for holding weighted objects to counterbalance the weight of the lining machine, and
- a weight distributor for distributing the weight of the forming frame and the weighted objects over a defined surface area sufficient to prevent damage to the new pipe lining, the weight distributor being configured as a pivot point on which the weight of the lining machine and the weight of the weighted objects are counterbalanced.
The apparatus of claim therein the adjusting means adjust a lean angle of the lining machine relative to the carriage.
