Description

Technical Field

[0001] This utility model relates to the field of transfer tooling technology, and in particular to a forklift mast painting transfer tooling. Background Technology

[0002] Forklift masts are complex, classified into two- or multi-level masts. Forklifts mostly use two- or three-level fully free masts. A two-level mast consists of an inner mast and an outer mast, and can be further divided into a basic mast and a two-level fully free mast. A three-level mast consists of an inner mast, a middle mast, and an outer mast. The specifications and lengths of the inner, middle, and outer masts vary depending on the load capacity and lifting height. As the main load-bearing structure of the forklift lifting system, the mast is heavy and long. Traditional painting methods use hooks to suspend individual masts into the painting line. Due to the long mast length, and the fixed length of the entire painting line, the number of masts that can be painted after entering the line is limited, resulting in low painting efficiency. After leaving the painting line, the masts need to be transferred from the painting line to the assembly line. If the masts are transferred directly by stacking them individually, the surface coating quality of the masts can easily be damaged. For the transport of masts of vehicles with large tonnage, the method of transporting individual masts one by one is often used. Only one mast section can be transported per trip, which results in low transport efficiency. In order to improve transport efficiency, a forklift mast painting and transport fixture was designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a forklift mast painting and transfer fixture, thereby improving transfer efficiency.

[0004] The forklift mast painting and transfer fixture proposed in this utility model includes two lower crossbeams, with multiple rectangular steel pipes welded and fixed between the lower crossbeams. Support plates are welded and fixed to the middle of the side walls of the lower crossbeams, and upper crossbeams are fixed to the top side walls of the support plates. A flipping frame is movably installed on the surface of the upper crossbeams.

[0005] The flipping frame includes a rotating support plate, and flipping support plates are symmetrically welded and fixed on both sides of the rotating support plate.

[0006] Preferably, the surfaces of the upper crossbeam plate and the flipping bracket plate are provided with pin holes of equal diameter, and a pin shaft is fitted between the upper crossbeam plate and the flipping frame.

[0007] Preferably, the top of the support plate has a receiving position that is adapted to the flip-up bracket plate.

[0008] Preferably, both the upper crossbeam plate and the flipping bracket plate are provided with limiting protrusions, and the flipping bracket and the upper crossbeam plate are used together to hold the gantry.

[0009] Preferably, the surface of the lower crossbeam plate is symmetrically provided with holding positions for holding the gantry.

[0010] Preferably, corner plates are additionally welded and fixed at the weld joints between the rectangular steel pipe and the lower crossbeam plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. Specialized painting hangers suitable for medium and large-sized gantry frames;

[0013] 2. After the gantry rolls off the painting line, it does not need to be transferred to a dedicated transfer fixture. The subsequent transfer processes can be completed directly through this lifting device, reducing intermediate steps and significantly improving transfer efficiency. Attached Figure Description

[0021] Reference Figure 1-6 The forklift mast painting and transfer fixture includes two lower crossbeam plates 1. Multiple rectangular steel pipes 4 are welded and fixed between the lower crossbeam plates 1. Support plates 2 are welded and fixed in the middle of the side walls of the lower crossbeam plates 1. Upper crossbeam plates 3 are fixed on the top side walls of the support plates 2. A tilting frame 6 is movably installed on the surface of the upper crossbeam plates 3.

[0022] The flipping frame 6 includes a rotating support plate 62, and flipping support plates 61 are symmetrically welded and fixed to both sides of the rotating support plate 62. (See reference) Figure 4 When using the lower crossbeam plate 1 at the bottom to place the gantry, the flipping frame 6 can be flipped to contact the upper crossbeam plate 3, freeing up the movement space required for gantry placement. When placing the upper gantry, the flipping frame 6 is rotated back to its original position, so that the flipping gantry and the upper crossbeam plate 3 together form a horizontal holding structure for gantry placement.

[0023] Both the upper crossbeam plate 3 and the tilting bracket plate 61 have pin holes of equal diameter. A pin shaft 7 is fitted between the upper crossbeam plate 3 and the tilting bracket 6. The top of the upper crossbeam plate 3 also has a hoisting hole for overall hoisting.

[0024] The top of the support plate 2 is provided with a receiving position 8 that is compatible with the flip bracket plate 61. The purpose of the receiving position 8 is to level the flip bracket plate 61 and achieve stable placement of the gantry.

[0025] Both the upper crossbeam plate 3 and the flipping bracket plate 61 are provided with limiting protrusions 9. The flipping bracket 6 and the upper crossbeam plate 3 are used together to hold the gantry. (Refer to...) Figure 5 .

[0026] The surface of the lower crossbeam plate 1 is symmetrically provided with holding positions 10 for holding the gantry, for reference. Figure 4 .

[0027] Angle plates 5 are additionally welded and fixed at the weld joints between the rectangular steel pipe 4 and the lower crossbeam plate 1.

[0028] When this device is in use, the upper crossbeam plate 3 and the lower crossbeam plate of the transfer frame are cut according to the gantry opening size, and the height of the support plate 2 is designed according to the height of the painting line. The upper crossbeam plate 3 and the tilting frame 6 are fixed with pins 7 and assembled to form a painting transfer fixture. Therefore, the tilting frame 6 can rotate nearly 180°.

[0029] When the tilting frame 6 is tilted from the horizontal direction to the other end, the overall length of the upper end of the tooling is shortened by half, and the gantry can be lifted by the crane and placed on the lower horizontal plate of the transfer frame. Then, the tilting frame 6 is tilted back, and the upper horizontal beam plate 3 and the tilting frame 6 are in a horizontal state. The gantry can be lifted by the crane and placed on the upper end of the transfer frame. The two lifting holes at the upper end of the transfer frame can be selected according to the height of the line.

[0030] After the two gantry sections are placed on the transfer fixture, they are hoisted onto the painting line according to the hoisting holes. After the painting is completed, the rectangular steel pipe 4 at the lower end of the fixture can not only serve as a connection strength but also be used for fixtures with placed workpieces, and can be transported back and forth by forklift.
