Embodiment Construction
[0023] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0024] Such as figure 1 As shown, the embodiment of the present invention includes: a working plate 1, a pull plate rod 2, a frame plate 3, a frame rod 4, a nut 5, a lifting screw 6, and a powerful disk 7.
[0025] Specifically, such as Figure 1-Figure 3 As shown, the working plate 1 has a rectangular plate-shaped structure, and a plurality of first long holes 11 and a driving hole 12 are provided thereon, and the plurality of first long holes 11 are symmetrically distributed on both sides of the driving hole 12. In the embodiment, the number of the first long holes 31 is two.
[0026] Such as figure 1 and Figure 4-Figure 5 As shown, this embodiment includes two pull-plate rods 2, but the number is not limited to this, and can be changed as needed, but the number is the same as the number of the first elongated holes. The upper end of the pull plate rod...

The invention provides a combined puller which comprises a work plate, a plurality of plate pulling rods, a lifting lead screw, a frame plate and a plurality of frame rods, wherein the work plate is provided with a plurality of first long holes and a drive hole, and the first long holes are symmetrically distributed in the two sides of the drive hole; the upper ends of the plate pulling rods movably penetrate through the first long holes respectively and are provided with separating prevention structures for preventing the plate pulling rods from being separated from the first long holes; the bottom of the lifting lead screw is inserted into the drive hole in the work plate, the upper end of the lifting lead screw is provided with a rotating drive structure, and the bottom end of the lifting lead screw is provided with a plate pulling structure, so that when the rotating drive structure drives the work plate to move, the lifting lead screw is prevented from being separated from the work plate; the frame plate is provided with a plurality of second long holes and a lead screw hole, the second long holes are symmetrically distributed in the two sides of the lead screw hole, and the lifting lead screw is meshed into the lead screw hole; the upper ends of the frame rods movably penetrate through the second long holes respectively and are provided with positioning structures for stably arranging the frame plate at the upper end of the frame rods. The combined puller can be flexibly used in a narrow space and is simple in structure, flexible to operate and wide in use range.
Description
Technical field [0001] The invention relates to the technical field of equipment maintenance, disassembly and installation tools, in particular to a combined puller. Background technique [0002] In the current industrial equipment, with the development of science and technology, the volume of the equipment is getting larger and the assembly accuracy is getting higher and higher. A large-scale equipment often requires a large number of parts to be assembled, and the complexity of the equipment is getting higher and higher. When one of the parts is damaged, it is limited by the equipment space and installation location, and sometimes requires tedious disassembly to complete the replacement of equipment parts. However, the current puller has a single structure and solidification, which is difficult to adjust in time, which affects work efficiency and use range. Summary of the invention [0003] The purpose of the present invention is to provide a combined puller to change the struc...
