[0028] In order to further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0029] See figure 1 with figure 2 , figure 1 It is a schematic diagram of the top view structure of the tank container assembly station of the present invention, figure 2 It is a schematic diagram of the side structure of the tank container assembly station of the present invention. The tank container assembly stand 1 of the present invention is used to assemble and weld the cylinder body 31 with end frames, top side beams, bottom side beams and other components according to technical requirements, or directly process the cylinder body 31 itself, for example, overflow Flow box polishing and matching operation, bottom discharge hole profiling operation. The tank container assembly station 1 includes an assembly area 10, a plurality of lifting platforms arranged in the assembly area 10, a plurality of station assembly stations, a fixed platform 15, a fixed platform 14, and a tank for carrying and conveying. The input and output equipment 11 of the barrel 31 of the container.
[0030] The input and output device 11 is an electro-hydraulic vehicle, and the cylinder 31 is placed horizontally above the electro-hydraulic vehicle. The electro-hydraulic vehicle inputs the barrel 31 from the input port at the front end of the assembly area 10 to the corresponding position of the first station assembly station 131 in the assembly area 10, and then the barrel 31 is transferred from the electro-hydraulic vehicle to the first station assembly On the platform 131, after the transfer is completed, the electro-hydraulic car will be removed from the first station assembly station 131. After the first station assembly is completed, the electro-hydraulic car will then transfer the assembled cylinder 31 to the next station assembly station. . According to the above transportation method, the electro-hydraulic vehicle transports the product to the second station assembly station and the third station assembly station for assembly. After the assembly of all stations is completed, the electro-hydraulic vehicle outputs the product from the output port at the back of the assembly area 10. .
[0031] The multiple lifting platforms include a first lifting platform 121, a second lifting platform 122, and a third lifting platform 123. The multiple station assembly stations include a first station assembly station 131 and a second station assembly station 132. , A third station assembly table 133. The first lifting platform 121, the second lifting platform 122, and the third lifting platform 123 are parallel to each other and arranged horizontally in the assembly area 10. The first station assembly station 131, the second station assembly station 132, and the third station assembly station 133 are arranged transversely between the first lifting platform 121 and the second lifting platform 122, between the second lifting platform 122 and the third lifting platform 123, and between the third lifting platform 123 and the fixed platform 15 respectively. The fixed platform 14 extends in the longitudinal direction from both ends of the first lifting platform 121 until it reaches the fixed platform 15. When the lifting platform is raised to the same height as the fixed platform 14, the fixed platform 14 communicates with the lifting platform. The platform 15 can also be connected to the fixed platform 14 through a ladder 101 to form an interoperable general assembly platform that can assemble the three work stations through each other, thereby increasing the activity space of the operators and improving the assembly efficiency. , A top side beam stacking area 1201 and a bottom side beam stacking area 1202 for stacking top side beams and bottom side beams can be respectively arranged above and below each lifting platform to increase the stacking space of parts and improve the utilization rate of space. Here, it should be noted that the first station assembly station 131 is mainly used to complete the assembly work of the overall shape of the tank container 1, such as the positioning and welding of the end frame, the top side beam, the bottom side beam and the cylinder 31 Work, the second station assembly station 132 mainly completes the bottom discharge hole profiling work, and the third station assembly station 133 mainly completes the grinding and matching work of the overflow box.

The frames 1215 interfere with each other and affect the structural stability and service life of the lifting platform 1211, the first lifting sliding frame 1214, the second lifting sliding frame 1215, and the interconnecting parts. The lifting platform 1211 of the present invention is fixed at one end , The floating structure design at the other end just solves the above problems.

The lateral adjustment unit 172 includes a screw rod 1722, a linear guide 1724, a screw nut 1723 arranged on the screw rod 1722, and a roller carrier base 1725 connected to the screw nut 1723. The screw rod 1722 is connected to the motor, the starter motor, and the screw rod When 1722 rotates, the screw nut 1723 on the screw 1722 moves linearly, and drives the roller carrier base 1725 to move along the linear guide rail 1724 in the lateral direction, thereby realizing the movement of the cylinder 31 in the lateral direction. Such as Figure 5a As shown in the figure, both the B area and the B'area are provided with the lateral adjustment unit 172, and the adjustment units 172 in the B area and the B'area have the same structural features, so they will not be repeated here.
