[0001] Machine for cleaning access mats FIELD
[0002] There is described a machine that was developed for the purpose of access mats.
BACKGROUND
BACKGROUND
[0003] In order to create a temporary road across environmentally sensitive areas, road mats are laid end to end. These road mats have come into common usage in the oil and gas industry during initial oil and gas exploration and to access service oil or gas well sites.
When using drilling rigs for drilling for oil and gas, it is not unusual for the entire site to be covered with rig mats the are placed side by side and end to end to support the drilling rig and associated equipment. The term access mats is used to describe dual purpose mats that can be used as either road mats or rig mats. For the purpose of this description, use of the term access mat shall be considered to include road mats and rig mats. At the end of a project, the site is restored and the access mats (both road mats and and rig mats) are moved to the next environmentally sensitive site where they are required.

For the purpose of this description, use of the term access mat shall be considered to include road mats and rig mats. At the end of a project, the site is restored and the access mats (both road mats and and rig mats) are moved to the next environmentally sensitive site where they are required.
[0004] An increased emphasis upon safety has lead to increased regulation and oversight by government authorities. Damage has been sustained by vehicles following trucks that are transporting access mats. The damage has been caused by chunks of snow and ice or mud and rock falling off the access mats during transport. Highway traffic authorities are now inspecting loads of access mats for such potential hazards. At the present time, this problem is being addressed by having heavy equipment that is used to load the access mats onto trucks also used to scrape off excessive buildups of snow and ice or mud and rock that are observed during the loading process.
SUMMARY
SUMMARY
[0005] There is provided a machine for cleaning access mats. Each mat has a first face, a second face, a first side edge, a second side edge and opposed ends. The machine includes a housing defining a processing tunnel through which each mat must pass. The processing tunnel has an inlet end and an outlet end. A first flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the first face of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. A second flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the second face of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. A
third flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the first side edge of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. A fourth flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the second side edge of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. Guides are provided for supporting and guiding each mat. A drive mechanism is provided for propelling each mat through the processing tunnel from the inlet end to the outlet end.
third flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the first side edge of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. A fourth flailing roller is provided for knocking accumulated snow and ice or mud and rocks from the second side edge of each mat as the mat passes from the inlet end to the outlet end of the processing tunnel. Guides are provided for supporting and guiding each mat. A drive mechanism is provided for propelling each mat through the processing tunnel from the inlet end to the outlet end.
[0006] With the machine, described above, considerable time is saved by simply feeding the mats sequentially into inlet end of the processing tunnel where they are flailed by the first, second, third and fourth rollers as they travel through the processing tunnel to the outlet end.
[0007] One area of the mat that is difficult to clean, even with flailing rollers is an interlock that is positioned at the opposed ends of the mat. For this reason, it is preferred that at least one interlock cleaning blade be provided. The interlock cleaning blade engages the interlock at each of the opposed ends of each mat passing through the processing tunnel to dislodge any accumulation of snow and ice or mud and rock from the interlock.
[0008] Access mats can be rejected and access refused to the next environmentally sensitive site due to a presence of environmental contaminants. These environmental contaminants can take a number of forms, such as weed seeds, insect larva, or invasive plant species. Where this is a potential issue, a spray assembly may be positioned in the processing tunnel downstream of the first, second, third and fourth flailing rollers. The spray assembly may simply provide a washing action or, where required, may deliver a chemical decontaminant to address the environmental contaminant identified.
