The invention discloses a rope, net, wire and belt abrasion resistance testing device and relates to a rope and net testing device. The rope, net, wire and belt abrasion resistance testing device comprises a friction testing mechanism, a constant-tension mechanism, a control mechanism and a cooling mechanism which are arranged inside a box body shell (9), wherein the constant-tension mechanism is connected with the friction testing mechanism and the cooling mechanism respectively in a pneumatic drive mode and used for achieving fixing of a test piece (31) of the friction testing mechanism and meanwhile achieving flushing and heat exchange of the cooling mechanism, the control mechanism is connected with the friction testing mechanism, the constant-tension mechanism and the cooling mechanism respectively, and operating state control of the whole device is achieved through a control panel (2) arranged at the top of the box body shell (9). The rope, net, wire and belt abrasion resistance testing device conducts corresponding adjustment on testing parameters according to different testing products, achieves testing of multiple samples, such as rope, nets, wires and belts, and is convenient to use, safe, reliable and wide in application range.
