[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a fan and a temperature sensor are provided. During use of the device, the infrared temperature sensor is aimed at the outside of the oil cylinder to detect the temperature of the outside of the oil cylinder. Through this operation mode, when the highest temperature area of ​​the oil cylinder is detected, the annular slider slides in the annular slide groove to drive the movable block to move, so that the fan can be moved to the highest temperature area on the oil cylinder, thereby completing the rapid cooling of the highest temperature area of ​​the oil cylinder, thereby increasing the functional stability of the oil cylinder.

[0018] The present invention is provided with a roller and a pressure sensor. Before the device is used, the roller abuts against the bottom of the first support rod connected to the oil cylinder. Then the staff operates the device to simulate the working state of the oil cylinder. At this time, through the lifting and lowering of the oil cylinder, the first support rod will squeeze the roller, and the roller will drive the second sliding block to slide inside the second slot, so that the spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system, and the background control system compares the pressure value with the standard pressure value. Through this operation mode, the lifting function detection of the oil cylinder can be completed before the device is used, thereby increasing the safety of the device.

[0019] When the device is transporting the workpiece, the roller moves to the bottom of the first support rod connected to the abutment cylinder. When one of the cylinders is slightly damaged, the force of the cylinder connecting to the first support rod to squeeze the roller downward will increase, and the pressure value will be abnormal when compared with the pressure value of the background control system. When the background control system detects this situation, it will issue a warning to the staff. After receiving the warning, the staff can take countermeasures in advance. Through this operation method, the danger prediction of the device during use can be completed, which can increase the operating safety of the staff;

[0020] After the use of the device, the first sliding block is rotated to a use state facing the oil cylinder by rotating the rotating block, and then the roller is allowed to abut the outside of the oil cylinder by extending and retracting the electric lifting rod, and then the movable block is rotated on the outside of the oil cylinder, and the abutment pressure difference between the roller and the oil cylinder during the rotation of the movable block is detected by the pressure sensor, and then the pressure difference is compared with the standard pressure difference to complete the detection of the deformation degree of the oil cylinder. Through this operation method, the oil cylinder can be maintained and replaced in time, which increases the safety of the device.

[0021] The present invention is provided with a cleaning block. When the device is not in use, the electric extension rod drives the cleaning block to extend. When the bottom of the cleaning block moves to the use position above the top of the roller, the cleaning block is driven to rotate by the rotating motor, so that the two cleaning blocks rotate close to each other until the cleaning sponges on the cleaning blocks rotate to a use state in which they abut against each other. Subsequently, the electric extension rod is extended to make the cleaning sponges abut against the outside of the oil cylinder. At this time, the movable block moves on the outside of the oil cylinder to clean the dust on the outside of the oil cylinder, preventing dust from accumulating on the outside of the oil cylinder and affecting the detection effect of the device, and preventing dust from adhering to the outside of the oil cylinder and weakening the heat dissipation effect of the device on the oil cylinder.

A rotating motor 23 is embedded and installed near the electric extension rod 15 on the cleaning block 16, and the installation end of the rotating motor 23 is connected to the extended end of the electric extension rod 15. When the device is not in use, the first sliding block 18 is rotated to a use state facing the oil cylinder 8 by rotating the rotating block 13, and then the electric extension rod 15 drives the cleaning block 16 to extend. When the bottom of the cleaning block 16 moves to the use position above the top of the roller 21, the cleaning block 16 is driven to rotate by the rotating motor 23, so that the two cleaning blocks 16 rotate close to each other until the cleaning sponges on the cleaning blocks 16 rotate to a use state in which they abut against each other, and then the cleaning sponges are extended by the electric extension rod 15 to abut the outer side of the oil cylinder 8. At this time, the movable block 9 moves on the outer side of the oil cylinder 8 to complete the cleaning of the dust on the outer side of the oil cylinder 8, thereby increasing the convenience of use of the device.

[0045] When the present invention is in use, the electric drive equipment used in the device is powered by an external power supply through a wire. The device controls the electrical equipment in the device by setting a control system. The moving parts 6, cylinders 8, mechanical protection locks 7, and hydraulic spring rail clamps 4 used in the device are all existing mature technologies, so they will not be elaborated on in detail. The method of load-balancing the first support rod 1 by the cylinder 8 is an existing mature technology, so it will not be elaborated on in detail. Each first moving block 3 and its two moving parts 6 form a double-track trolley, and four of the six double-track trolleys used in the device are active double-track The trolleys, two of which are passive double-track trolleys, both the active double-track trolleys and the passive double-track trolleys are existing mature technologies, so they will not be elaborated on in detail, and the overall beam transport vehicle is moved by moving the bottom track wheel of the moving part 6 on the track of the bottom bracket 32.

The lifting devices are existing mature technologies, so they will not be elaborated on in detail.

[0046] Before the device is used, the movable block 9 is extended upward by the electric telescopic rod 30 and combined with the electric lifting rod 14 to extend upward, so that the roller 21 abuts the bottom of the first support rod 1 connected to the oil cylinder 8. At this time, the height of the roller 21 is higher than the height of the mechanical protection lock 7. Then the staff controls the device to simulate the working state of the oil cylinder 8. At this time, the oil cylinder 8 contracts downward, and the first support rod 1 will squeeze the roller 21. The roller 21 will drive the second sliding block 20 to slide toward the inside of the second slot 25, so that the spring telescopic rod 26 squeezes the pressure sensor 27. The pressure sensor 27 transmits the measured pressure value to the background control system, and the background control system compares this pressure value with the standard pressure value. Through this operation method, it can simulate the actual use of the device. When the load on the partition of the first support rod 1 is uneven, the oil cylinder 8 is lifted to complete the adjustment of the balance of the first support rod 1, thereby completing the detection of the lifting function of the oil cylinder 8 itself before the device is used, thereby increasing the safety of the device.

[0047] When the device is transporting the workpiece, the roller 21 moves to abut the bottom of the first support rod 1 connected to the cylinder 8. When one of the cylinders 8 is slightly damaged, the supporting capacity of the cylinder 8 is reduced. The force of the cylinder 8 connecting to the first support rod 1 to squeeze the roller 21 downward will increase, and this pressure value will be abnormal when compared with the pressure value of the background control system. When the background control system detects this situation, it will issue a warning to the staff. After receiving the warning, the staff can take countermeasures in advance. Through this operation method, the danger prediction of the device during use can be completed, which can increase the operating safety of the staff.

[0048] During use of the device, the electric rotating shaft 22 drives the rotating block 13 to rotate, so that the first sliding block 18 rotates to the use direction facing the oil cylinder 8. At this time, the infrared temperature sensor 19 is aligned with the outside of the oil cylinder 8, and the movable block 9 is driven to move up and down by the electric telescopic rod 30. Combined with the sliding mode of the annular slider 11 in the annular slide groove 10, the infrared temperature sensor 19 can detect the temperature of different parts of the outside of the oil cylinder 8, thereby detecting the use temperature of the oil cylinder 8, and through this operation mode, when the highest temperature area of ​​the oil cylinder 8 is detected, the movable block 9 is driven to move by the sliding of the annular slider 11 in the annular slide groove 10, so that the fan 12 can be moved to the highest temperature area on the oil cylinder 8, thereby completing the rapid cooling of the highest temperature area of ​​the oil cylinder 8, thereby increasing the functional use stability of the oil cylinder 8.

[0049] After the use of the device, the first sliding block 18 is rotated to a use state facing the cylinder 8 by rotating the rotating block 13, and then the roller 21 can abut the outside of the cylinder 8 by extending and retracting the electric lifting rod 14, and then the movable block 9 is rotated on the outside of the cylinder 8. The abutment pressure difference between the roller 21 and the cylinder 8 during the rotation of the movable block 9 is detected by the pressure sensor 27, and then the pressure difference is compared with the standard pressure difference to complete the detection of the deformation degree of the cylinder 8. Through this operation method, the cylinder 8 can be maintained and replaced in time, which increases the safety of the device.

[0050] When the device is not in use, the first sliding block 18 is rotated to a use state facing the cylinder 8 by rotating the rotating block 13, and then the electric extension rod 15 drives the cleaning block 16 to extend. When the bottom of the cleaning block 16 moves to the use position above the top of the roller 21, the cleaning block 16 is driven to rotate by the rotating motor 23, so that the two cleaning blocks 16 rotate closer to each other until the cleaning sponges on the cleaning blocks 16 rotate to a use state in which they abut against each other, and then the cleaning sponges abut against the outside of the cylinder 8 by extending the electric extension rod 15. At this time, the movable block 9 moves on the outside of the cylinder 8 to clean the dust on the outside of the cylinder 8, prevent dust from accumulating on the outside of the cylinder 8 and affecting the detection effect of the device, and prevent dust from adhering to the outside of the cylinder 8 to weaken the heat dissipation effect of the device on the cylinder 8.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
