the guide bearing 14 is arranged on the connecting rod 13 and used for being abutted against and limited by the inner wall of the C-shaped square pipe 5;
wherein, be provided with the sensor on the C shape side's pipe to whether rotate to antifriction bearing and/or direction bearing and detect.
Particularly, the height of the inside of the C-shaped square pipe is preferably larger than the diameter of the rolling bearing, so that when the guide trolley moves in the C-shaped square pipe, the rolling bearing only contacts with the top surface or one surface of the inner bottom surface of the C-shaped square pipe, and the rolling bearing can roll smoothly; the width of the inner part of the C-shaped square pipe is preferably larger than the diameter of the guide bearing, so that when the guide trolley moves in the C-shaped square pipe, the guide bearing only contacts with one side of the inner left side surface or the inner right side surface of the C-shaped square pipe, and the guide bearing can roll smoothly.
Specifically, the sensor can be a friction force sensor, when the friction force sensor is installed, a window can be formed in the bottom of the C-shaped square pipe, the friction force sensor is installed on the window, the detection surface of the sensor is flush with the inner bottom surface of the C-shaped square pipe, when the guide trolley passes through, the rolling bearing of the guide trolley can be judged to roll or slide (the rolling friction force is far smaller than the sliding friction force), whether the rolling bearing of the guide trolley is damaged or not is judged, and similarly, the friction force sensor can also be installed on the side surface of the C-shaped square pipe, and whether the guide bearing is damaged or not is detected.
In addition, the sensor can also be a displacement sensor, when the displacement sensor is installed, a strip-shaped hole can be formed in the bottom of a C-shaped square pipe, the displacement sensor is installed on the outer bottom surface of the C-shaped square pipe, a stroke rod of the displacement sensor moves along the conveying direction or the reverse conveying direction, a contact piece is arranged on the inner bottom surface of the C-shaped square pipe, the contact piece is connected with the stroke rod of the displacement sensor through a connecting rod penetrating through the strip-shaped hole, if a rolling bearing of the guide trolley rolls, the friction force between the rolling bearing and the contact piece is small, the contact piece cannot be dragged to move forwards, but the rolling bearing of the guide trolley slides, the friction force between the rolling bearing and the contact piece is large, the contact piece can be dragged to move forwards, and whether the rolling bearing of the guide trolley is damaged or not can be judged through signals of the displacement sensor. In a similar way, the displacement sensor and the contact piece can also be arranged on the side surface of the C-shaped square pipe to detect whether the guide bearing is damaged and does not rotate.
In the use process of the embodiment, the starting motor drives the head wheel roller 6 to rotate, the head wheel roller 6 drives the upper layer of the conveying belt 9 to move towards the tail wheel roller 7 along the conveying direction, after the direction of the conveying belt is changed by the tail wheel roller 7, the lower layer of the conveying belt 9 moves towards the head wheel roller 6 along the conveying direction, in the moving process of the conveying belt 9, the guide trolley 15 connected with the conveying belt 9 moves synchronously with the conveying belt 9 along the running track, and the guide trolley 15 is always limited in the running track, so that the conveying belt 9 is also limited, and the drifting deviation of the conveying belt in the running process is avoided.
