Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of curtain wall material construction and transportation, in particular to a heavy-duty mold which changes the transportation mode of a forklift. Background Art
[0002] During conventional curtain wall construction, forklifts are commonly used to transport materials, but this traditional lifting and transportation method has limitations. For example, when transporting small amounts of glass or aluminum window frames protected by wooden planks, the limitations of this lifting and transportation method can lead to problems such as the inability to transport multiple or diverse materials at once. Furthermore, without additional securing measures during transportation, there is a risk of tipping over. In traditional construction, cranes or tower cranes are typically used to transport small amounts of glass or aluminum window frames. Compared to forklifts, transporting the same amount of material requires more manpower and carries greater risks. Furthermore, existing forklift transportation methods present certain difficulties when navigating complex sites and confined spaces, limiting their applicability. Traditional lifting methods also introduce additional vibration and impact, potentially damaging the glass and window frame materials. This is crucial in curtain wall projects, which demand high quality exterior facades. Utility Model Content

[0013] The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.
[0014] Reference Figure 1The utility model is a heavy-duty mold that changes the transportation mode of forklifts. It includes a square mold formed by welding steel at the bottom to perfectly fit with the forklift, a supporting steel frame 1, and a single steel 2 on the top. The square mold includes a frame surrounded by first steel pipes 3 and second steel pipes 4 alternately. The middle parts of the first steel pipes 3 and the second steel pipes 4 are fully welded with three steel sheets, and the supporting steel frame 1 is connected by punched bolts. A forklift fork scale 5 is installed at the tail of the two first steel pipes 3. The bottom of the supporting steel frame 1 is connected to the frame by bolts, and the top is welded and fixed to the top single steel 2 by bolts to form a load-bearing frame; three R-shaped steel plates of the same specification are welded at equal intervals on the lower part of the top single steel 2. , a hook is installed at the lower end of each R-shaped steel plate, and two equal-height R-shaped steel plates 6 are installed on the upper part of the top single steel 2. A lifting steel 7 is welded in the middle to increase the height of the pulley set at the top, and a wire rope 9 is arranged between the pulleys. In the present utility model, the mold usage requirements must be clarified according to the tonnage and fork scale size of the forklift. Taking a 3t forklift as an example, the standard configuration of the fork scale is 1070mm, and the extended 1220mm, 1370mm, 1520mm, 1670mm, etc. can be selected. The specific size of the heavy-duty mold that can be assembled will also be different according to the different fork scale configurations. The present invention uses the normal 3t forklift standard fork scale as the mold carrier. The main profile of this heavy-duty mold is Q235A, and the skeleton steel of the heavy-duty mold is mainly hollow square steel of 60*80*6mm, 80*90*6mm, and 100*90*6mm. The steel skeletons are connected by welding and bolts to ensure the stress performance. Triangular stress areas are formed in many positions to ensure the safety and stability of the structure when transporting goods, and additional stress stability verification can be performed.
[0015] According to the principle of torque lever, it is easy to know that under the premise of using only one steel hook at a time, the steel hook at the front end of the mold is the minimum load-bearing point, and the force verification needs to be focused on. The maximum load-bearing capacity of the forklift mold is 510 kg, so it is necessary to focus on the verification and analysis of the position of the steel hook at the front end of the mold.
[0016] In the present invention, the bottom of the heavy-duty mold is formed by welding steel to form a square mold that can perfectly fit with the forklift. A square steel with a slightly larger size and thicker wall is selected near the forklift fork scale 5, specifically the first steel pipe 3, to ensure the durability and ease of operation of this mold. The middle part is fully welded with three-sided steel sheets, and the supporting steel frame is connected with punched bolts. The square steel at the far fork end is the second steel pipe 4, two L-shaped steel sheets are fully welded on both sides of the upper part, and three-sided steel sheets are fully welded in the middle. Holes are punched for bolting the supporting steel frame 1. The mold supporting steel frame 1 is fixed to the top and bottom of the mold by bolt connection and full welding to form the main force-bearing frame, wherein multiple positions can form triangular force. Three R-shaped steel plates 6 of the same specification are welded at equal intervals at the lower front end position of the single steel 2 profile at the top of the mold. Small, medium and large-sized steel hooks are installed from the far end to the near end as the main force-bearing components for transporting materials. Two equal-height R-shaped steel plates 6 are welded at the top position of the single steel 2 profile at the top of the mold, and a lifting steel is welded in the middle to increase the height of the top pulley. The lifting steel is a 60*80*6mm hot-dip galvanized steel pipe.
[0017] In the present invention, the first steel pipe 3 is a 100*90*6mm hot-dip galvanized steel pipe, the second steel pipe 4 is an 80*90*6mm hot-dip galvanized steel pipe, and a galvanized trapezoidal steel plate 8 is arranged between the supporting steel skeleton 1 and the top single steel 2, and between the supporting steel skeleton 1 and the frame, and is fixedly connected by an M16 stainless steel bolt group 10. The supporting steel skeleton 1 and the top single steel 2 are both made of 60*80*6mm hot-dip galvanized steel pipe material, the thickness of the 60*80*6mm hot-dip galvanized steel pipe is 23mm, and the steel wire rope 9 is a 5.0mm galvanized steel wire rope 9.
[0018] The implementation method of the utility model is as follows:
[0019] 1. Choose the steel hooks according to the material stacking position (height, distance from the wall) and weight. Steel hooks of different specifications and sizes can be freely replaced.
[0020] 2. During the welding process of each steel component, ensure that the 50*120*6mm steel pipe is vertical and free of deformation. Pay attention to the quality of the weld (no undercuts, pores, cracks, etc.). After the construction is completed, promptly carry out anti-corrosion and anti-rust treatment. This directly affects the safety and service life of the mold.
[0021] 3. All parts fixed with bolts shall use M16 bolts, and accessories such as square washers and spring washers shall not be missing.
[0022] 4. After welding and bolting the overall structure, the steel surface needs to be sanded to remove rust, oxide layers, and burrs, achieving a smooth surface and enhancing surface adhesion. A water-based iron red primer is used as the primer for the entire steel. Apply one or two coats by brush, and proceed to the next step after drying. Fluorocarbon paint is used as the topcoat and can be applied by brush, roller, or spray. When painting, follow the principle of "painting the large surfaces first, then the details" to ensure an even coating. The number of coats will be determined by the design requirements.
[0023] 5. The top steel rope zipper can be freely replaced with different lengths, thicknesses of steel ropes and locks according to different usage environments to secure goods or tighten them to improve the integrity and load-bearing capacity of the mold.
[0024] This utility model utilizes a specially designed metal mold installed on the forklift's fork 5, enabling the forklift to transition from a lifting mode to a hook-hook mode. This innovative method effectively addresses the challenge of efficiently transporting materials without pallets or additional securing measures. It prevents the tipping of materials such as glass and aluminum alloy window frames protected by slender wooden planks, improving transportation safety and ensuring efficient and economical transport. The invention aims to provide a more efficient, reliable, and economical solution for transporting curtain wall materials.
[0025] As above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
