Description

Technical Field

[0001] This utility model relates to the field of production technology, and in particular to an auxiliary device for improving the stacking efficiency of gantry frames. Background Technology

[0002] In the forklift manufacturing industry, it's sometimes necessary to stack semi-finished masts to save floor space. However, the racks used for stacking masts, with their independent rotating support plates, require manual rotation of the support plates when placing the second mast after the first layer. This increases operator workload, impacts efficiency, and introduces a safety hazard. The new auxiliary device, with its redesigned rotating support plates and added connecting plates, allows the second rotating support plate to be pre-positioned to support the second mast after the first layer is in place. This ensures support when the second mast arrives. Similarly, once the second layer is in place, the third rotating support plate is pre-positioned to support the third mast. This eliminates the need for manual rotation of the support plates, reducing operator workload and improving efficiency. It also indirectly enhances operational safety. Utility Model Content

[0003] The technical problem solved by this utility model is that in the scenario of stacking gantry semi-finished products, it is necessary to manually rotate the rotating support plate, which increases the operator's work, affects work efficiency, and also adds a safety risk.

[0005] Load-bearing frame;

[0006] The columns are welded together, with at least two columns, and are fixedly installed on the top surface of the load-bearing frame and extend vertically upwards;

[0010] A connecting plate, one end of which is rotatably connected to the linkage end, and the other end is coupled to the linkage end of the rotating support plate on it;

[0011] The gantry is placed on the support end of the bottom rotating support plate. Pressing the support end rotates it to the horizontal position. At this time, the fixed end is vertically upward, and the rotating support plate above it is driven to move in conjunction through the connecting plate.

[0012] According to this utility model, the rotating support plate is further comprising three groups, which are evenly arranged along the vertical direction of the column welding.

[0013] According to this utility model, the coupling point where the rotating support plate is welded to the column is located on the side biased towards the support end.

[0014] According to this utility model, the two sides of the connecting plate are a round hole and a strip hole, respectively. The strip hole is arranged longitudinally, and the rotating support plate located above it is coupled to it. During the rotation, the coupling component moves from the bottom of the strip hole to the top of the strip hole to complete the rotation movement.

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0031] Please see Figure 1 , Figure 2 As shown in the figure, this application embodiment provides an auxiliary device for improving the stacking efficiency of a gantry, including a load-bearing frame 1, which serves as the main support and provides overall support. At least two upright welded joints 2 are welded to the top surface of the load-bearing frame 1. Each upright welded joint 2 extends vertically upwards and is coupled with a rotating support plate 3 for supporting the gantry. There are at least two rotating support plates 3, distributed along the vertical direction of the upright welded joints 2. The two rotating support plates 3 arranged vertically are connected by a connecting plate 4, enabling the linkage of adjacent rotating support plates 3. The connecting plate 4 is a strip-shaped plate, with its lower end rotatably connected to the rotating support plate 3 below it and its upper end rotatably connected to the rotating support plate 3 above it. After connection, the connecting plate 4 allows adjacent rotating support plates 3 to move together.

[0032] Specifically, please refer to Figure 5The rotating support plate 3 includes a linkage end 31 and a support end 32 that is perpendicular to it and integrally formed. The connecting plate 4 is rotatably connected to the linkage end 31. In the unused state, the support ends 32 of the two lower rotating support plates face the space between the two columns welded together 2 and are inclined upwards. The support ends 32 of the two upper rotating support plates are parallel to the column welded together 2, and the linkage end 31 points to the side away from the column welded together 2.

[0033] Please see Figure 6 The connecting plate 4 has a round hole and a strip hole on each side, with the longitudinal center line of the strip hole coinciding with the longitudinal center line of the connecting plate 4. The linkage end 32 of the rotating support plate has a round hole, and the round hole at the bottom of the connecting plate 4 engages with the round hole at the linkage end 32 of the bottom rotating support plate. The rotating shaft passes through both round holes, enabling the two to rotate at the connecting end. The strip hole at the top of the connecting plate 4 is connected to the round hole at the linkage end 32 of the upper rotating support plate via a rotating shaft. During the rotation of the upper rotating support plate 3, the rotating shaft moves from the bottom of the strip hole to the top of the strip hole, realizing the transmission of linkage motion.

[0034] In this embodiment of the application, to improve the support stability of the auxiliary device, please refer to... Figure 3 and Figure 4 The load-bearing frame 1 is square, and four uprights 2 are welded to the four corners of the load-bearing frame 1. Each upright 2 is coupled with three rotating support plates 3. Adjacent rotating support plates 3 are linked by connecting plates 4. The coupling point between the rotating support plate 3 and the upright 2 is located on the side biased towards the support end 32. When the support end 32 is rotated to a horizontal position by external force, the linkage end 31 is located outside the upright 2, preventing motion interference and ensuring smooth linkage. The working method of the auxiliary device in this embodiment is as follows:

[0035] Step 1: Visually inspect the initial position of the rotating support plate: Please refer to... Figure 7 The first layer of rotating support plates has an initial tilt angle (approximately 45° horizontally). This initial tilt angle ensures that the distance between the two rotating support plates 3 is smaller than the width of the gantry. This ensures that when the first gantry is stacked, the two oppositely positioned rotating support plates 3 can support the gantry. Simultaneously, this small initial tilt angle prevents the second layer of rotating support plates from rotating, allowing the support ends 32 of the second layer of rotating support plates to be in a relatively vertical position (approximately 90° horizontally). This also ensures that the distance between the second layer of rotating support plates 3 is wider than the gantry, facilitating the placement of the gantry.

[0036] Step 2, Place the first gantry: Please refer to Figure 8When the first gantry is placed on the bottom rotating support plate, the gantry presses down on the support end 32 of the first rotating support plate, pressing the support end 32 of the rotating support plate to a horizontal position. Because the bottom rotating support plate 3 is pressed from an inclined position to a horizontal position, the connecting plate 4 causes the support end 32 of the adjacent rotating support plate to rotate to an inclined position (approximately 45° horizontal). This ensures the support of the second gantry when it is stacked. At the same time, this initial inclination angle is small and will not cause the rotating support plate 3 above it to rotate, thus keeping the support end 32 of the third rotating support plate in a relatively vertical position (approximately 90° horizontal), ensuring that the spacing between the third rotating support plates is wider than that of the gantry.

[0037] Step 3, Place the second gantry: Please refer to Figure 9 When the second gantry is placed on the second layer, the gantry presses down on the support end 32 of the rotating support plate on the second layer, pressing the support end 32 of the rotating support plate to a horizontal position. Because the support end 32 of the rotating support plate on the second layer is pressed from an inclined position to a horizontal position, the connecting plate 4 causes the support end 32 of the rotating support plate on the third layer to rotate to an inclined position (approximately 45° horizontal). This ensures that the gantry can be supported when the third gantry is stacked.

[0038] Step 4, Place the third gantry: Please refer to Figure 10 When the third gantry is placed on the third layer, the gantry presses onto the support end 32 of the rotating support plate on the third layer, pressing the support end 32 of the rotating support plate to a horizontal position.

[0039] In summary, the auxiliary device of this utility model, through the combination of a load-bearing frame, welded columns, rotating support plate, and connecting plate, constitutes a reliable, practical, and simple gantry stacking auxiliary device. Its main application scenario is in the production activities of gantry, when it is necessary to stack gantry semi-finished products, reducing operation steps, reducing stacking time, thereby improving employee work efficiency, and also improving work safety.
