Nut blocks are threadedly installed on the rod body of the bidirectional screw at intervals. A hollow clamping rod is fixedly installed at the lower end of the nut block. A support screw is rotatably installed inside the hollow clamping rod, and a bottom plate is fixedly installed at the lower end of the support screw. The patent can realize the fixed support of the container from multiple directions by cooperating with the hollow clamping rod and the bottom plate, thereby improving the stability of the container lifting. The overall fixing effect of the device is good, the lifting stability is high, and the manufacturing cost is low, the practicality is high, and it is easy to promote.

[0004] The above technical solution twists the bidirectional screw rod through the handle, and the rotating bidirectional screw rod drives the two nut blocks to move toward each other, and then drives the two hollow clamping rods to move toward each other, so as to clamp and fix the container. However, the device needs to be manually operated and the locking cap needs to be manually twisted to fix it each time, which increases the labor intensity of the workers. Utility Model Content

[0006] The technical solution to achieve the purpose of the utility model is: a container lifting device, including a mounting plate, two lifting rings are fixedly installed on the top wall of the mounting plate, and also includes;

[0007] A reciprocating motor, wherein the reciprocating motor is fixedly mounted on the top wall of the mounting plate, threaded rods are fixedly mounted on two output ends of the reciprocating motor, two through holes are provided on the side wall of the mounting plate, guide rods are slidably mounted on the inner side walls of the through holes, a movable plate is slidably sleeved on the side walls of the guide rods, sleeve rods are fixedly mounted on both sides of the bottom wall of the movable plate, limiting plates are fixedly mounted on both ends of the side walls of the two guide rods, and connecting rods are fixedly mounted on the side walls of the sleeve rods.

[0008] In some embodiments, a limit block is fixedly mounted on the top wall of the connecting rod, and the wall of the limit block on one side away from the sleeve rod is inclined.

[0009] In some embodiments, two fixing blocks are fixedly mounted on the top wall of the mounting plate, and two threaded rods penetrate the two fixing blocks respectively.

[0010] In some embodiments, a spring is fixedly mounted on the inner top wall of the sleeve rod, and a support rod is fixedly mounted on the other end of the spring.

During the unloading process, the universal wheel 7 will first contact the ground before the container lands. Then, during the descent of the mounting plate 1, the support rod 5 can be gradually retracted into the inner side of the sleeve rod 4, so that the spring 42 absorbs the impact force transmitted by the support rod 5, thereby improving the stability of the container when it lands, avoiding collision when the container lands and causing chaos of the internal goods, and improving safety. Finally, the reciprocating motor 2 is remotely started to drive the threaded rod 21 to rotate in the opposite direction, so that the distance between the movable plates 22 on both sides is increased, and at the same time, the connecting rod 6 is separated from the container top lifting ring 11, so that the mounting plate 1 is separated from the container to complete the unloading, and no manual operation is required, which simplifies the lifting process and reduces the labor intensity of workers.
