[0015] The present invention will now be described in detail with reference to specific embodiments:
[0016] like Figs. 1 to 4 The diagram shows a dual-station transport trolley on a small cylindrical welding conveyor line, comprising a hydraulic lifting platform 1, linear guide rails 2, support blocks 3, a drive motor 4, and wheels 5. The wheels 5 are installed at the four corners of the base of the hydraulic lifting platform 1, and the four wheels 5 are placed on the linear guide rails 2. The left and right sets of wheels 5 are fixedly connected by a central axle. The drive motor 4 is fixedly installed on the base of the hydraulic lifting platform 1, and the drive motor 4 is connected to the central axle of one set of wheels 5 through a transmission wheel and a transmission belt. The eight support blocks 3 are divided into two symmetrical groups and fixedly installed on the top frame of the hydraulic lifting platform 1, forming a V-shaped support area between the support blocks 3 in the same group.
[0017] The top frame of the hydraulic lifting trolley 1 is provided with a two-stage lifting mechanism at both ends, which is composed of a support 6, a fixed carrier 7, a movable carrier 8 and a hydraulic cylinder 9. The support 6 is fixedly installed on the top frame of the hydraulic lifting trolley 1. The fixed carrier 7 is fixedly installed on the support 6. The cylinder body of the hydraulic cylinder 9 is fixedly installed on the fixed carrier 7. The piston rod of the hydraulic cylinder 9 is fixedly connected with the movable carrier 8 by sliding through the fixed carrier 7. The same set of supporting blocks 3 are fixedly installed on the movable carrier 8. The supporting surface of the supporting block 3 is fixedly installed with a pad 31 by screwing. The piston rod of the hydraulic cylinder 9 drives the fixed carrier 7 and the supporting block 3 combination to move synchronously up and down. In the case that the height position of the hydraulic lifting trolley 1 is fixed, the single-sided supporting block 3 is lifted by the two-stage lifting mechanism. The pad 31 has an anti-skid function. After the pad 31 is worn out, it can be replaced by simply disassembling it.
[0018] The movable carrier 8 is fixedly installed with a guide column 71 in a rectangular distribution. The fixed carrier 7 is fixedly installed with a guide sleeve. The guide column 71 is slidingly installed in the guide sleeve. The cooperation of the guide column 71 and the guide sleeve can improve the straightness of the upward and downward movement of the movable carrier 8.
[0019] The frame of the hydraulic lifting trolley 1 is made of high-strength steel material, which has good rigidity and stability and can withstand the weight of small cylinder bodies and various forces during transportation.
[0020] The same set of supporting blocks 3 form a bearing mechanism, and the bearing mechanism is provided with a group, which can simultaneously or separately bear different small cylinder bodies. The V-shaped supporting area can adapt to the positioning needs of small cylinder bodies of various diameters, ensuring that the small cylinder bodies maintain stable positions during transportation.
[0021] The driving system is composed of a driving motor 5, a speed reducer and a wheel 5. The driving motor 5 is a servo driving motor. The driving motor provides power. The speed reducer converts the high-speed rotation of the motor into low-speed large-torque output suitable for the wheel 5. The wheel 5 is usually made of materials with good wear resistance and shock absorption performance to ensure the stability of the hydraulic lifting trolley 1 during transportation. The servo driving motor can accurately control the positioning.
[0022] The control system takes PLC as the core and can receive instructions from the main control system of the welding conveying line to control the lifting of the hydraulic lifting trolley 1, the start and stop of the driving motor 5 and the speed reducer, and the extension and retraction of the piston rod of the hydraulic cylinder 9. It is also equipped with an operation box to facilitate manual control by the operator.
[0023] The positioning principle of the hydraulic lifting trolley 1 moving along the linear guide rail 2 is as follows: when the hydraulic lifting trolley 1 runs to the specified work position, the sensor detects the signal and sends it to the control system, and the control system controls the driving system to stop running, so as to realize the precise positioning of the double-station carrying trolley on the linear guide rail 2. The small cylinder welding carrying trolley is equipped with an accurate positioning system and a stable transportation structure, which can ensure the position accuracy and stability of the small cylinder during transportation, provide protection for high-quality welding, reduce welding defects caused by transportation problems, and improve the qualified rate of products.
[0024] The work flow of taking, feeding, welding and discharging is as follows: the small cylinder conveying line is provided with a notch matched with the top frame of the hydraulic lifting trolley 1, and when the double-station carrying trolley feeds and discharges from the conveying line, the top frame of the hydraulic lifting trolley 1 can freely move up and down in the notch of the conveying line. When taking, the hydraulic lifting trolley 1 is lowered to the lowest, the right side bearing mechanism fork is inserted into the conveying line, the hydraulic lifting trolley 1 is lifted to take out the small cylinder, the carrying trolley runs directly below the girth weld special machine, the hydraulic lifting trolley 1 is lowered, the small cylinder falls on the feeding and discharging bracket of the welding special machine, the carrying trolley performs the next process, at the same time, the feeding and discharging bracket of the welding special machine is lifted, the girth weld equipment clamps the cylinder body, the RFID scans and reads the cylinder information for welding operation, the left end bearing mechanism of the carrying trolley takes the small cylinder from the left conveying line, the carrying trolley runs a distance on the side of the welding special machine, the right end bearing mechanism of the carrying trolley waits for the welded cylinder under the welding special machine, after the right end bearing mechanism of the carrying trolley receives the welded cylinder, the bearing mechanism on the left end bearing mechanism of the carrying trolley feeds the small cylinder on the feeding and discharging bracket of the welding special machine, and the carrying trolley places the welded cylinder received by the right end bearing mechanism on the right end conveying line and then receives the cylinder.
