Description

Technical Field

[0001] The utility model relates to the field of metallurgical workpiece packaging, in particular to a cast pipe packaging vehicle. Background Art

[0002] Ductile iron pipe (referred to as cast pipe) is a pipe made by high-speed centrifugal casting of molten iron by centrifugal ductile iron casting machine after adding spheroidizing agent. Socket-type pipe joints are usually used between adjacent pipe bodies, so there is a situation where the outer diameter of the pipe body is inconsistent. At present, both at home and abroad, cast pipes need to be packaged after production before they can be transported. The main packaging method at home and abroad is to complete the packaging manually, which is as follows: first, the cast pipes are placed in a staggered manner according to the sockets, and then the middle pads are placed between each layer of ductile iron pipes. The bottom layer needs to be placed with grooved bottom wood, and finally the steel belt for packaging is passed through the groove of the bottom wood to complete the packaging.

[0003] Whether before or after packaging, or during transportation, multiple cast pipes need to be constrained, and their spatial positions must be constrained to form a rectangular shape before they can be packaged or transported after packaging. Especially in the process of packaging and transporting small and medium-caliber cast pipes, since a single cast pipe is long, it is necessary to provide a transportation device that is convenient for later packaging, and a simple basket structure cannot be used for stacking.

[0004] Therefore, there is an urgent need for a transport trolley that is convenient for packaging and can be adjusted into a stack shape according to packaging requirements. Summary of the invention

[0039] In order to overcome the technical defect of the prior art that there is no packing and transporting trolley, the inventor uses a swing arm type restraint method and designs a barrier arm that can be laid flat and upright at the four corners of the load-bearing platform. The barrier arm is set at the end to avoid blocking the insertion of the packing belt or the pad, thus achieving the dual functions of restraining the bundling before packing and safe transportation after packing. Figures 1 to 5 The technical solution adopted by the present invention is: a cast pipe packaging vehicle, comprising:

[0040] The trolley 100 is a powered transport trolley. In the present application, the transport trolley proposed should not be limited to a trolley driven by a power mechanism or constrained on a track, but should also include a trolley with an intelligent operating system, such as an AGV trolley.

[0041] A scissor lift device 200 is fixed to the upper part of the trolley 100;

[0042] The packing base 300 is located at the lifting end of the scissor lift device 200 and is a horizontally arranged rigid plane;

[0043] During transportation, the cast pipes are placed on the upper part of the packaging base 300 in multiple rows and columns in the form of a rectangular parallelepiped;

[0044] The innovation of the present application is to integrate the tooling for packaging and transportation on the basis of the lifting trolley in the prior art. The present application scheme also includes: four sets of swing arm assemblies 400 located on the outer side of the end of the packaging base 300 and fixedly connected on both sides of the axial direction of the cast pipe, and the packaging base 300 is divided into two sets along one side of the axial direction of the cast pipe; the two sets of the swing arm assemblies 400 located at the same end of the packaging base 300 are mirror-symmetrical; please refer to Figure 3 During the design process, the inventor took into account the influence of the swing radius of the swing arm on the plane of the packaging base 300, and specially designed the swing arm assembly 400 at the end to utilize the end space to reduce the influence of the swing on the plane of the packaging base 300.

[0045] The swing arm assembly 400 includes:

[0046] The arm slide 410 is a long strip of slot body with a C-shaped cross section; the back of the arm slide 410 C-shaped structure is fixedly connected to the packaging base 300 and protrudes from the packaging base 300 along the length direction; please refer to Figure 5 The C-shaped structure referred to in the present application does not simply refer to a C-shaped structure with an arc circumferential edge, but refers to a C-shaped structure with one end open and the movable part 450 can be mounted inside and slide relatively.

[0047] The movable portion 450 is sleeved inside the barrier arm slide groove 410 and can slide relatively along the barrier arm slide groove 410;

[0051] The retaining arm 440 is flipped with the help of the linear drive device 420 and can be in a vertical position on the plane where the packaging base 300 is located; in some packaging operations, the retaining arm 440 is not completely perpendicular to the plane, which depends on the packaging form. At present, the packaging of cast pipes adopts a rectangular stacking structure, but in some non-socket packaging processes of steel pipes, they will be packaged into a diamond shape. The inventor believes that although it is limited to vertical, on the basis of the same function, there is reason to believe that the upright position with a certain inclination angle is equivalent to the vertical position described in this application.

[0052] The driving part drives the movable part 450 to move. The function of the driving part is to realize the movement of the interface part 430, which can be driven by a gear rack, a cylinder, an oil cylinder, an electric steel, etc.

The trolley 100 is transported to the station for wrapping the strapping tape, or in the stopped position, the packaging and bundling machine passes the strapping tape through the gaps between the support ribs 310 to package into bundles / stacks. The above operations can also be completed manually. After packaging is completed, the trolley 100 is transported to the outbound station, and the bundled / stacked cast pipes are loaded into the outbound carrier by the equipment. When the order has requirements for the size of the bundle / stack, or the outbound carrier has requirements for the size, the position of the movable part 450 or the length of the support plate 320 is adjusted to meet the corresponding size.

[0063] Compared with the prior art, the utility model has the following beneficial effects: integrating transportation and lifting, and cooperating with the swing arm assembly to realize the restraint and transportation of the cast pipes before and after packaging; using the screw rod to realize the extension and extension of the blocking arm, so that when the width of the stacked cast pipe increases, it can be adjusted; using the crank and the screw rod to realize simple manual adjustment.
