Description

Technical Field

[0001] The present invention relates to the technical field of improved processes for transport large chains, and particularly to an improved process for the transport large chain of a frame-type support carrier vehicle. Background Art

[0002] In the material transportation links of industries such as coal mining and heavy machinery manufacturing, the transportation of the conveyor large chain and the transfer machine large chain is an extremely important part. As a key component, the safety and efficiency of the large chain transportation directly affect the smooth progress of subsequent production operations.

[0003] The conveyor large chain and the transfer machine large chain are usually loaded by a special large chain bucket. The current transport large chain bucket is relatively large in size and requires an 80-ton frame-type support carrier vehicle or a scraper-type support carrier vehicle for transportation. During the use of the frame-type support carrier vehicle, due to the narrow gap between the U-shaped frame and the large chain bucket and the small lifting holes, the hook cannot be firmly hung into the lifting holes.

[0004] Therefore, aiming at the problem that when the frame-type support carrier vehicle is used in combination with the traditional large-sized large chain bucket, the hook cannot be firmly hung into the lifting hole, resulting in unstable connection of the transport large chain, inconvenient operation, and insufficient safety guarantee, an improved process for the transport large chain of the frame-type support carrier vehicle can be designed. Summary of the Invention

[0007] Preferably, in step S2, the disassembly tool is selected according to the specific connection structure between the lifting hook and the frame-type bracket transporter. For the lifting hook connected with the standard hexagonal bolt, a wrench of the corresponding specification is selected; for the connection with the hexagonal bolt, a socket wrench is selected; for the scenario that requires quick disassembly, a ratchet wrench is selected.

[0008] Preferably, in step S3, the connection portion between the lower end of the lifting chain and the butterfly ring is cleaned before connection to remove oil, rust and other impurities to ensure that the connection surface fits tightly.

[0009] Preferably, in step S3, a torque wrench is used to perform the connection operation according to the specified tightening torque to ensure uniform connection strength. Anti-loosening nuts and spring washers are used as anti-loosening measures to prevent the connection from loosening due to vibration during transportation. Tensile testing equipment is used to perform a tensile test on the entire connection to verify the firmness of the connection and ensure that there is no risk of loosening or slipping.

[0010] Preferably, the supporting connection device in step S4 uses bolts and pins that have undergone high-strength heat treatment and surface anti-corrosion treatment, and the specifications of the bolts and pins are accurately selected according to the load-bearing weight of the large chain bucket and the connection size of the fixed lifting ring and the butterfly ring.

[0011] Preferably, in step S4, an electric wrench is used to tighten the bolts according to the specified tightening torque to ensure that the tightening degree of each bolt is consistent to avoid connection failure due to uneven force; or a hydraulic pin installer is used to accurately drive the pin into the pin hole to ensure that the pin is firmly installed; and during the installation process, a diagonal detection method is used to ensure that both sides of the large chain bucket are firmly installed, including using an angle measuring instrument to measure the inclination angle on both sides of the large chain bucket.

[0012] Preferably, in step S4, the driver can use the precise positioning auxiliary system equipped on the frame-type support transporter, including a laser positioning device, to emit a laser beam to accurately mark the alignment position of the fixed lifting ring and the butterfly ring; use the camera monitoring system to transmit the image of the connection between the large chain bucket and the lifting chain in real time, and the driver can clearly observe the connection status through the display screen inside the vehicle.

[0013] Preferably, in step S5, an angle sensor installed on the large chain bucket is used to real-time monitor the inclination angle of the large chain bucket, and a displacement sensor is used to real-time monitor the lifting height and horizontal displacement of the large chain bucket. These sensors are connected to the central control system of the frame-mounted support vehicle. Once the detected inclination angle or displacement of the large chain bucket exceeds the preset threshold, the central control system will automatically issue an alarm and stop the lifting operation, and the driver can make timely adjustments according to the feedback information to ensure good balance and fixation of the large chain bucket during the lifting process.

[0014] Preferably, in step S6, the intelligent monitoring system equipped on the vehicle can real-time monitor the status of the large chain bucket, including monitoring the connection condition between the fixed lifting ring and the butterfly ring of the large chain bucket through image recognition technology, and once any abnormality is found, the driver will be reminded to take measures in a timely manner.
