Benefits of technology

[0013]According to an optional feature, each frame is further equipped along one side with at least one downwardly opening bracket and along its other side with at least one upwardly opening bracket so that the frames may be interlocked to prevent lateral separation by lowering one frame relative to the other so that the downwardly opening bracket(s) engage the upwardly opening bracket(s).

Problems solved by technology

One problem, however, that characterizes prior art rig mats having disengagable interlocking element assemblies is that mud, dirt and / or ice can accumulate and block in between the locking elements, thereby making the engagement and disengagement of two adjoining mats difficult.

Embodiment Construction

[0026]Reference is made to FIGS. 1-7.

[0027]In use a plurality of rig mats 1 will be interlocked end to end to form a longitudinally aligned arrangement or, alternatively, they will also be interlocked laterally to form a wider arrangement (as shown in FIG. 4).

[0028]One such rig mat 1 will now be described.

[0029]The rig mat 1 comprises a rectangular frame 2 formed of steel wide-flanged I-beams (hereinafter referred to as ‘beams’). The frame has first and second ends 2a, 2b. The frame 2 is formed by a pair of side beams 3a, 3b, a first end beam 4a and a second end beam 4b. In the drawings the end beam 4a is shown as the front beam and the end beam 4b as the rear beam. Each of the side beams 3a, 3b have top and bottom flanges 5, 6. The front end beam 4a has only a top flange 5 while the rear end beam 4b has top and bottom flanges 5, 6. The side and end beams 3a, 3b / 4a, 4b are welded together at their ends. As shown, the frame 2 may be reinforced with an additional longitudinally extend...

Abstract

A pair of disengageably interlocking rig mats are provided. The rig mats are engaged to prevent longitudinal separation. An interlocking mechanism of key and receiver is provided. The key is lockably, slidably engaged with the receiver by lateral movement of one mat relative to the other. The mats are configured such that the interlocking mechanism is protected from dirt and debris.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part application of U.S. patent application Ser. No. 12 / 609,859 filed Oct. 30, 2009, which claims priority from Canadian Patent Application No. 2,642,380 filed Oct. 30, 2008. Each of these applications is hereby incorporated by reference in its entirety as if set forth herein in full.FIELD OF THE INVENTION[0002]The present invention relates to a rig mat having disengagable means for locking to another rig mat.BACKGROUND OF THE INVENTION[0003]“Rig mats” are very rugged, load-bearing mats used, for example, to support the base of a drilling rig in the oil and gas industry or to form a roadway over which heavy, loaded trucks may pass, where the terrain is unstable or environmentally sensitive.[0004]A typical conventional rig mat may comprise:[0005]a rectangular peripheral frame formed by wide flanged, steel I-beams that are welded together at each end to form the four corners of the rectangular frame;[00...
