TECHNICAL FIELD

[0001] The utility model relates to the equipment technical field of corrugated board production, especially to a supporting and lifting structure and a tool for rack assembly. BACKGROUND

[0002] In the unit equipment of corrugated box production linkage line, such as paper feeding, printing, drying, line pressing, slotting, die cutting, oscillation and box pasting, the structures of the racks are mostly similar, and each includes two wallboards and a plurality of upper and lower support rods installed between the two wallboards, so as to build a machine frame with the two wallboards and the plurality of upper and lower support rods, facilitating the installation of the processing structure of the unit equipment in or outside the rack.

[0003] At present, the assembly of the rack often relies on manual assistance for assembly and calibration. The specific process is as follows: first, the lower support rods are installed between the bottoms of the two wallboards, and then the upper support rods are installed between the tops of the two wallboards. When the lower support rods are installed, the lower support rods can be supported by the shims. However, when the upper support rods are installed, the upper support rods are mainly lifted to the position between the tops of the two wallboards by a crane, and then installed in the lifted state. There is a lack of structure for supporting the upper support rods, the assembly efficiency is low, and there is a certain safety risk. SUMMARY

[0004] The utility model aims to provide a supporting and lifting structure and a tool for rack assembly, so that the supporting and lifting structure supports the upper support rods when the upper support rods are installed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A supporting and lifting structure is installed on a displacement support, which includes two lifting arms and two groups of lifting and lifting modules. The displacement support has a positioning surface at one end for abutting against a wallboard. The two groups of lifting and lifting modules are arranged on the side surfaces of the displacement support. Each lifting and lifting module includes two bearing seats arranged opposite to each other on the top and bottom of the side surface of the displacement support, a lifting screw rotatably arranged between the two bearing seats, a lifting seat capable of lifting along the lifting screw with the rotation of the lifting screw, and a rotary drive module for driving the rotation of the lifting screw.

[0007] Each lifting arm is installed on a lifting seat corresponding to each lifting arm, which includes a hinge seat and an arm rod. One end of the hinge seat is hinged to the lifting seat, and the other end of the hinge seat is provided with the arm rod. When the lifting seat lifts along the lifting screw, the lifting arm is lifted, and the hinge seat rotates around the hinge with the lifting seat, and the arm rod is swung into the direction of the positioning surface of the displacement support. The lifting rod can be placed between the arm rods of the two lifting arms in the swung state, so that the lifting rod supports the upper support rods.

[0008] As a further technical scheme of the utility model: the side surface of the displacement support is provided with lifting rails parallel to the lifting lead screws, lifting blocks are slidably arranged on the lifting rails, and the lifting blocks are connected with the lifting seats.

[0009] In addition, the utility model provides a rack assembly tool with the support lifting structure.

[0010] A rack assembly tool comprises an assembly platform, a positioning support, a displacement support, a displacement driving structure, a plurality of auxiliary jacks and a support lifting structure. The positioning support is mounted at one end of the top of the assembly platform to position a wallboard. The displacement driving structure and the displacement support are mounted at the other end of the top of the assembly platform. The displacement support can be displaced relative to the positioning support under the driving of the displacement driving structure to position another wallboard. The assembly platform forms an assembly area between the positioning support and the displacement support. The plurality of auxiliary jacks are arranged at the bottom of the assembly area to support an upper support rod when the two wallboards are positioned.

[0011] Compared with the prior art, the utility model has the advantages that the support lifting structure and the rack assembly tool can support an upper support rod with lifting rods when the upper support rod is installed, effectively improve the rack assembly efficiency, and make the assembly process safer and reduce the labor intensity in the assembly process.
