The working principle of the invention is as follows: when the traction device is used, the traction wheel to be detected is placed between the two vertical plates, the traction wheel is fixed on an output shaft of the motor, then one end of the pin shaft is inserted into a central hole of the traction wheel, and then the other end of the pin shaft is fixed in the pin hole. And then sliding the base to enable the base to move towards the traction sheave, wherein a support plate is fixedly connected to the base, a detection piece corresponding to each sliding groove of the traction sheave is arranged on the support plate, a display screen is arranged on the support plate and is in electrical signal connection with the detection piece, the base moves towards the traction sheave until each detection piece is positioned in the sliding groove corresponding to the traction sheave and is in contact with the bottom of the sliding groove, at the moment, the motor is started, the traction sheave is fixed on an output shaft of the motor, the motor drives the traction sheave to rotate when the motor operates, and the detection piece transmits a pressure value between the detection piece and the traction sheave to the display screen when the traction sheave rotates for one circle and displays the pressure value through the display screen. At the moment, whether the abrasion degree of each sliding groove and the abrasion degree of each sliding groove are the same or not can be known according to the pressure value on each display screen.
The invention has the beneficial effects that: this scheme is through detecting piece and driving the driving sheave rotation through motor and traction sheave spout direct contact, and the place that the spout wearing and tearing degree is strong this moment then and the distance between the detection piece is a little far away, so the pressure value that detects will be less, and the place that the wearing and tearing degree is weak then and the distance between the detection piece advances a little, so the pressure value that detects will be great. The wear condition of the traction sheave can be rapidly detected through the scheme, and whether the wear degree of each sliding groove is the same or not can be directly known.
Further, every the detection piece includes a fixed cylinder, and a fixed cylinder is fixed on the extension board, piston connection has the movable rod in the fixed cylinder, the spring has been cup jointed on the movable rod, be equipped with pressure sensor on the fixed cylinder, pressure sensor is located between a fixed cylinder and the spring, and every pressure sensor corresponds a display screen, and pressure sensor and the display screen signal connection who corresponds, the one end fixedly connected with fixed block of a fixed cylinder is kept away from to the movable rod, rotates on the fixed block to be connected with and is used for stretching into the gyro wheel in the spout. When the traction device is used, the idler wheels are positioned in the sliding grooves of the traction wheel, if the abrasion degree of each sliding groove of the traction wheel is different, the length of each movable rod in the fixed cylinder is different under the elastic force action of the spring when the movable rod is extended and is in contact with the sliding groove, and the abrasion degree of each sliding groove is different at the moment. Because the length of the movable rod extending under the action of the elastic force of the spring is different, the deformation amount of the spring is also different, so that the sliding groove is seriously abraded, the movable rod extends out longer under the action of the elastic force of the spring, the pressure generated by the spring on the pressure sensor is smaller at the moment, the pressure value transmitted to the display screen by the pressure sensor is also smaller, and the abrasion degree of the sliding groove can be known to be serious.
Further, a ball bearing is arranged in the pin hole. Its purpose reduces the frictional force between round pin axle and the pinhole through this kind of setting, avoids sending out heat and scalding because of frictional force is too big to lead to rotating the junction.
Further, the roller is made of rubber. The roller made of rubber has certain flexibility, and cannot be in hard contact with the traction wheel, so that the traction wheel is prevented from being secondarily damaged or secondarily abraded due to the hard contact in the detection process.
Furthermore, the contact surface of the idler wheel and the sliding groove of the traction wheel is provided with anti-skid lines. Its purpose is, through this kind of setting avoid the gyro wheel to skid.
