Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workpiece movement, in particular to a lifting frame. Background Art
[0002] During the transportation of wash basins, the wash basins need to be transported from the first-level conveyor line to the second level. Due to the various specifications and sizes of wash basins, when traditional lifts encounter irregular shapes or a certain difference in weight on both sides, the cylinders on both sides will not lift synchronously during lifting, which will cause the slider connected to the frame to be stuck on the guide rod. Summary of the invention
[0003] The utility model aims to provide a lifting frame with cylinders on both sides lifting synchronously during lifting.
[0004] The lifting frame of the utility model is implemented as follows, including a frame, cylinders arranged on both sides of the frame, and a movable frame driven to rise and fall by the cylinders. The special feature of the utility model is that more than one set of lifting auxiliary mechanisms are arranged, and the lifting auxiliary mechanisms include lower pulleys fixed on both sides of the bottom of the frame, upper pulleys arranged on both sides of the top of the frame, and two ropes wound around the lower pulley and the upper pulley, one of which is connected to one side of the movable frame and passes through the lower pulley on one side, the upper pulley on one side, and the upper pulley on the other side in sequence, and then is connected to the other side of the movable frame, and the other rope connected to the other side of the movable frame passes through the lower pulley on the other side, the upper pulley on the other side, and the upper pulley on one side in sequence, and then is connected to one side of the movable frame.
[0005] During the transportation of the wash basin, the wash basin is placed on a movable frame, and the cylinders on both sides drive the movable frame to rise and fall so as to transfer the wash basin to the corresponding shelf. During the lifting process, as one side of the movable frame rises and falls, the two ropes driven by it also synchronously drive the other side of the movable frame to rise and fall, thereby avoiding the situation where the cylinders on both sides of the traditional lift are not lifted synchronously when encountering wash basins with various specifications and sizes or with a certain weight difference on both sides.
[0006] Preferably, a pair of lower pulley frames, a pair of upper pulley frames and a pair of lifting frame fixing members are provided, the lower pulley is fixed on the lower pulley frame, the upper pulley is fixed on the upper pulley frame, one end of the two ropes is connected to one of the lifting frame fixing members, the other ends of the two ropes are connected to the other lifting frame fixing member, the upper pulley is connected to the top of the frame through the upper pulley frame, the lower pulley is connected to the bottom of the frame through the lower pulley frame, and the ends of the ropes are connected to the movable frame through the lifting frame fixing member. In this way, the lifting auxiliary mechanism can be installed on the original lifting frame through a pair of lower pulley frames, a pair of upper pulley frames and a pair of lifting frame fixing members without changing the original lifting frame structure, which facilitates the modification of the original lifting frame.
[0007] Preferably, there are two sets of lifting auxiliary mechanisms, which are respectively arranged on the front and rear sides of the movable frame.
[0008] Compared with the prior art, the utility model has the advantage that the cylinders on both sides can be lifted synchronously during lifting. BRIEF DESCRIPTION OF THE DRAWINGS
