Description

Technical Field

[0001] The utility model belongs to the technical field of port engineering, and in particular relates to a clamping device used for cutting rectangular steel pipes. Background Art

[0002] Rectangular steel pipes are used in the construction of port projects. At the construction site, it is often necessary to use an electric saw to cut rectangular steel pipes. At this time, workers usually put the rectangular steel pipe to be cut on the ground, hold the rectangular steel pipe with one hand, and use the other hand to cut the rectangular steel pipe with an electric saw. During the cutting process, because the worker needs to hold the rectangular steel pipe to be cut with one hand, he can only use the other hand to hold the electric saw for cutting. When the worker's physical strength decreases, the hand holding the electric saw will swing, resulting in poor precision of the cut rectangular steel pipe, which does not meet the use requirements; sometimes, after the rectangular steel pipe is cut, the electric saw cuts the ground, which not only damages the ground, but also damages the electric saw, reducing the service life of the electric saw; sometimes, the electric saw even cuts the worker's palm pressing the rectangular steel pipe.

[0003] Based on the above problems, the port engineering site needs a self-made simple steel pipe clamping device for cutting rectangular steel pipes that is easy to make, easy to use, safe and reliable, and low in cost. Utility Model Content

[0006] The fixed limit block is provided with a fixed sleeve installed on the horizontal cantilever, and a fixed clamping plate is provided on the fixed sleeve. The sliding limit block is provided with a sliding sleeve installed on the horizontal cantilever, and a movable clamping plate is provided on the sliding sleeve.

[0007] The fixed clamping plate and the movable clamping plate are both made of angle steel and are arranged back to back.
