On-board firefighting capstan comprehensive testing device and testing method thereof

Abstract

The invention relates to an on-board firefighting capstan comprehensive testing device. The on-board firefighting capstan comprehensive testing device comprises a control system, a power mechanism, a breaking testing device, and a capstan testing device. A breaking testing oil cylinder and a first traction rope test piece are vertically fixedly connected with an experimental testing arm. The end of the first traction rope test piece is fixedly connected with a first fixing device. The capstan testing device comprises a capstan tension sensor, a capstan installation rack, and a power roller device. A tested capstan is fixedly disposed on the capstan installation rack, and two ends of a second traction rope are respectively disposed on the tested capstan and a drum in a coiled manner. The on-board firefighting capstan comprehensive testing device is advantageous in that an application range is wide; an industrial brake is adopted, and a range of carrying capacity is adjustable; the fast installation of the capstan and the adjustment of the lengths of the traction ropes are realized, and the extending angles of the traction ropes are adjustable, and testing adjustment at different angles can be simulated conveniently.

Description

technical field [0001] The invention relates to a comprehensive test device for a vehicle-mounted fire winch, belonging to the technical field of vehicle-mounted fire winch testing. Background technique [0002] There are two types of vehicle-mounted winches: electric winches and hydraulic winches. At present, the load of the winch test device is divided into manual and automatic. The manual device needs to be manually controlled by reading instrument data. The automatic test device can test electric winches and hydraulic winches. Follow the setup procedure to load, test and record the results. The Chinese patent document whose authorized notification number is CN203148658U discloses a "testing device for a winch", which can only be used to test the load resistance of the winch mechanism as a whole. In addition, the Chinese utility model patent with the authorized announcement number CN201233291Y discloses an "intelligent test bench for electro-hydraulic control winch", whi...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is: the existing vehicle-mounted fire winch testing device has a single function, and cannot obtain test parameters such as voltage and current for electric motors, and cannot directly obtain test parameters such as flow rate and pressure for hydraulic motors ;The test load force is not adjustable, which makes it impossible to simulate different loads conveniently; it is impossible to simulate the working performance of the winch traction rope at different angles; the breaking test of the winch accessories is inconvenient and the test accuracy is not high; The impact force is large, easy to damage, and it is quite different from the real situation of the initial force of the vehicle-mounted fire winch
