Abstract
The utility model discloses an outer anticorrosive layer stripping test cart of a steel tube, which comprises a cart frame, walking wheels, a tension sensor, a clamp and a hauling device. The cart frame is a gantry cart frame and comprises two groups of triangular support legs which are arranged symmetrically, a beam and a support arranged at the lower portion of the cart frame. Two walking wheels are arranged below each group of the triangular support legs, and the walking direction of the walking wheels accords with the length direction of the beam. The hauling device is fixedly arranged on the support, and the tension end of the hauling device is sequentially connected with the tension sensor and the clamp. The outer anticorrosive layer stripping test cart of the steel tube has the advantages that an inclined angle is formed by a steel wire rope and the axial line of the steel tube when the steel wire rope is strained, and leads the tension of the steel wire rope to produce a vertical upward component force and a horizontal component force. When the horizontal component force is acted on an outer anticorrosive layer test bar, the outer anticorrosive layer test bar produces a reactive force which drives the cart frame to move forward, thereby realizing constant speed loading, and guaranteeing accuracy of a test.
