The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a lifting device for a preform box provided in the present invention.
The utility model provides a lifting device of prefabricated excellent box, the structure is as shown in figure 1, including frame 4, load-bearing platform 3 and elevating system 2. Wherein, frame 4 includes base and crane, and crane and load-bearing platform 3 all set up on the base. The crane is located one side of load-bearing platform 3, the lower part and the base fixed connection of crane, and elevating system 2 is located the crane. Bearing platform 3 is used for placing and supporting prefabricated excellent box, and elevating system 2 links to each other with bearing platform 3, is used for driving bearing platform 3 and goes up and down. The lifting device further comprises a controller connected with the lifting mechanism 2, and the controller can send a control instruction to the lifting mechanism 2 so as to control the lifting mechanism 2 to lift. The controller can be a singlechip, an MCU microcontroller and the like.
Alternatively, the lifting mechanism 2 may include a lead screw, a nut, and a driving motor. As shown in figure 1, the lifting frame is of a rectangular frame structure, and the screw rod is arranged in the lifting frame along the vertical direction. Specifically, the upper portion of crane is equipped with the installation roof beam, is equipped with the connecting block on the installation roof beam, and the connecting block is rotationally connected with the lead screw. The lower part of the mounting rack is also provided with a connecting block. The driving motor is positioned in the base, and the screw rod penetrates through the connecting block at the lower part of the mounting frame to be in transmission fit with the driving motor. The nut is sleeved on the periphery of the screw rod and is fixedly connected with the bearing platform 3. Meanwhile, the screw nut is in threaded connection with the screw rod, so that the screw rod rotates to drive the bearing platform 3 to move in the vertical direction. Of course, the user may select an air cylinder or an oil cylinder as the lifting mechanism 2 according to the requirement, which is not limited herein.
Optionally, 2 upper portions of elevating system are equipped with the proximity switch that is used for detecting 3 high of load-bearing platform, and when load-bearing platform 3 reached appointed height, proximity switch sent the signal that targets in place to the controller, and then the steerable driving motor stall of controller to carry out follow-up operation to prefabricated excellent box.
In one embodiment of the present application, the lifting mechanism 2 is a screw rod. In order to limit the rotation of the load-bearing platform 3, the lifting frame is also provided with a linear guide rail 1. As shown in figure 1, the linear guide rails 1 are positioned on two sides of the screw rod, and the linear guide rails 1 can support the bearing platform 3 from two sides in the rotation process of the screw rod, so that the circumferential force generated by the screw rod is offset. In addition, the bearing platform 3 is provided with a guide groove which is in clearance fit with the linear guide rail 1. Further limiting the bearing platform 3.
In another embodiment of the present application, the lifting mechanism 2 employs at least two lead screws. Two lead screws are respectively connected with the bearing platform 3 through nuts and driven by the driving motor to synchronously rotate, and the two lead screws can jointly act to limit the rotation of the bearing platform 3.
The material of the prefabricated rod is brittle, so that the prefabricated rod is easy to crack due to sudden motion and sudden stop. The preform box needs to be slowly accelerated and decelerated during the lifting process. Therefore, the driving motor is a speed regulating motor, and the controller is connected with the speed regulating motor. The controller can slowly accelerate in the first half section of rising and slowly decelerate in the second half section according to a preset speed control curve. The impulse generated by the sudden speed change is prevented from damaging the preform rod on the premise of ensuring the rapid lifting.
In addition, the preform box needs to be fixed on the carrying platform 3 during the lifting process. Thus, the load-bearing platform 3 is provided with a fixing mechanism 5. Specifically, the fixing mechanism 5 is a clamping block located on the side of the bearing platform 3 except for the lifting frame, as shown in fig. 1, clamping blocks are arranged on the two sides of the bearing platform 3 except for the lifting frame, and the other side of the bearing platform is used for loading the prefabricated rod box. The clamping block is provided with a clamping screw. The clamping screw is matched with the box body of the prefabricated rod box for fixing. Of course, the user may also use an air cylinder, an oil cylinder or an electromagnet to fix the preform box as required, which is not limited herein.
In this embodiment, elevating gear can replace the transportation dolly to go up and down to prefabricated excellent box, therefore the transportation dolly only need shift prefabricated excellent box can. The length of occupying of the transfer trolley is reduced, and the use efficiency of the transfer trolley is improved. In addition, the speed regulating motor is matched with the screw rod, so that the speed regulation of the lifting process is realized. On one hand, the prefabricated rod box can be lifted at a higher speed, and the lifting efficiency is improved; on the other hand, the driving motor is slowly accelerated in the lifting process, so that the prefabricated rod is prevented from being damaged by the inertia force.
