Abstract
A maintenance device for remotely maintaining the inside of a structure, for example, by deploying a maintenance tool to remotely clean, sandblast using various blast media, and/or paint an interior surface of a building structure.
Claims13
1:
- A device adapted to maintain an inner surface inside of a structure, the device comprising:
- a support system that extends inside of the structure;
- a lifting system coupled to the support system inside the structure;
- a maintenance arm including at least one maintenance tool that is coupled to the lifting system, the maintenance arm configured to perform a maintenance action to the inner surface;
- and
- wherein the lifting system is configured to move the maintenance arm up and/or down within the structure.
3 more elements
2:
- The device of claim 1, further including a drive arm coupled to the support structure, wherein the drive arm is configured to move the maintenance arm around the inner surface of the structure.
3:
- The device of claim 2, wherein the drive arm is configured to move the maintenance arm in an approximately horizontal plane within the structure and wherein the lifting system moves the drive arm and maintenance arm in an approximately vertical plane within the structure.
4:
- The device of claim 3, wherein the drive arm is coupled to the lifting system in a position approximately opposite a position of the maintenance arm.
5:
- The device of claim 1, wherein the support structure includes an anchor and at least one support cable, the anchor configured to secure the support structure at or near a top portion of the structure and the at least one support cable extending into the structure where is it coupled to a position at or near a bottom location of the structure, the lifting system coupled to the at least one support cable.
6:
- The device of claim 5, the lifting system including at least one lifting cable and at least one lifting device, the at least one lifting cable having a first end that is attached to a location at or near the top of the structure and a second end that is attached to the lifting device, the lifting device configured to move the lifting system up and down along the at least one support cable.
7:
- The device of claim 6, wherein the at least one lifting cable includes a first lifting cable and a second lifting cable, and the at least one lifting device includes a first lifting device and a second lifting device;
- wherein the first lifting cable has a first end that is attached to a location at or near the top of the structure and a second end that is attached to the first lifting device, the first lifting device configured to move the lifting system up and down along the at least one support cable;
- wherein the second lifting cable has a first end that is attached to the maintenance arm and a second end that is attached to the second lifting device, the second lifting cable extending through a point at or near the top of the structure, the second lifting device configured to move the maintenance arm in a vertical plane.
8:
- The device of claim 7, wherein the at least one lifting cable includes a third lifting cable and the at least one lifting device including a third lifting device;
- wherein the third lifting cable has a first end that is attached to the drive arm and a second end that is attached to the third lifting device, the third lifting cable extending through a point at or near the top of the structure, the third lifting device configured to move the drive arm in a vertical plane.
9:
- The device of claim 8, wherein a swivel plate connects the anchor to the first support cable and is configured to allow rotation of the lifting system about the inner side of the structure.
10:
- The device of claim 8, wherein the drive arm is a telescoping arm.
11:
- The device of claim 8, wherein the maintenance arm is a telescoping arm.
12:
- The device of claim 1, wherein the maintenance tool is a blasting device.
13:
- The device of claim 8, the lifting system further including a base plate and wherein the base plate is coupled to the support cable and each of the lifting devices, the maintenance arm, and the drive arm are coupled to the base plate.
