Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to an adjustable large-item unloading and transportation device. Background Technology

[0002] Heavy-duty unloading and transportation equipment is a specialized engineering device designed for the safe and efficient handling of goods. It primarily addresses the problems of traditional tools being unable to bear the load, ill-suited to the size of the goods, or prone to damage. Forklifts play a multi-functional hub role in unloading and transportation, using their mast lifting mechanisms to match the unloading height of trucks and containers, eliminating the need for manual handling.

[0003] During the unloading and transportation of goods by forklifts, the distance between the forks on both sides needs to be adjusted according to the width of the opening on the pallet. Traditionally, this is achieved by loosening a large number of locking bolts (usually 2-4) one by one with a wrench, then manually pushing the forks to slide, and finally retightening the bolts. This method of adjusting the forks is cumbersome, requiring the rotation of numerous locking bolts, which is inconvenient for users. Therefore, there is an urgent need for an unloading and transportation device that facilitates the adjustment of the distance between the forks on both sides. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable large-item unloading and transportation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable heavy-duty unloading and transport device includes a gantry. Multiple support rods are fixedly mounted on the gantry. Adjustable forks are installed at both ends of the support rods. A fixed post is provided behind each fork, and a locking post is vertically and movably mounted on each fixed post. Adjustment cavities are provided on each support rod corresponding to the fixed posts. Multiple locking cavities adapted to the locking posts are provided on both sides of the adjustment cavities. A pressure plate for pressing the locking posts is vertically and movably mounted above the support rods.

[0007] In addition, a preferred structure is that each of the fixed columns has a transverse cavity, and the transverse cavity is adapted to and engaged with the adjustment cavity.

[0008] In addition, in a preferred structure, each of the fixed columns has a downward-facing vertical cavity at its top, the locking columns are adapted to move within the vertical cavity, and the vertical cavity is adapted to communicate with the horizontal cavity.

[0009] Furthermore, in a preferred configuration, each locking pin has a side cavity, and the side cavities are adapted and aligned with the locking cavity.

[0010] In addition, a preferred structure is that guide posts are adapted to fit the pressure plates on both sides of the top of the support rod, and the pressure plates are guided to move by the guide posts.

[0011] In addition, a preferred structure is that a lead screw is adapted to the top of the support rod corresponding to the pressure plate, and the pressure plate moves vertically via the lead screw.

[0012] The beneficial effects of this utility model are as follows: by locking the locking pin in different locking cavities and pressing and fixing the locking pin with the pressure plate, the forks can be fixed in different positions, thereby realizing the adjustment of the distance between the forks on both sides. The adjustment method in this device is simple and quick, and convenient for users to use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5An adjustable large-item unloading and transportation device includes a gantry 1. Multiple support rods 3 are fixedly mounted on the gantry 1. Adjustable forks 2 are installed at both ends of each support rod 3. A fixed post 20 is installed behind each fork 2, and a locking post 23 is vertically movably mounted on each fixed post 20. Adjustment cavities 31 are adapted to each fixed post 20 on each support rod 3. Multiple locking cavities 32 adapted to the locking posts 23 are opened on both sides of each adjustment cavity 31. A pressure plate 4 for pressing the locking posts 23 is vertically movably mounted above the support rod 3.

[0021] Each of the fixed columns 20 has a transverse cavity 21, and each transverse cavity 21 is adapted to and snapped into the adjustment cavity 31. By snapping the transverse cavity 21 into the adjustment cavity 31, stable support for the forks 2 can be achieved.

[0022] Each of the fixed posts 20 has a downward-facing vertical cavity 22 at its top, and each locking post 23 is adapted to move within the vertical cavity 22, with the vertical cavity 22 communicating with the horizontal cavity 21. Each locking post 23 has a side cavity 24, which is aligned with the locking cavity 32.

[0023] The support rod 3 has guide posts 41 on both sides of its top, corresponding to the pressure plate 4, and the pressure plate 4 is guided to move by the guide posts 41. The guide posts 41 improve the stability of the pressure plate 4 during movement.

[0024] The support rod 3 has a lead screw 42 fitted to the top of the pressure plate 4, allowing the pressure plate 4 to move vertically via the lead screw 42. A knob is provided on the lead screw 42, allowing the user to rotate it and thus adjust the pressure plate 4 vertically. A lead screw hole is provided on the pressure plate 4 to fit the lead screw 42, and both the lead screw 42 and the lead screw hole are equipped with a threaded damping locking mechanism. It is worth noting that these are existing technologies and not part of the technical problem of easy adjustment required by this solution; therefore, they will not be elaborated upon further.

[0025] In this embodiment, the mast 1 is fixedly mounted on the vertical moving mechanism of the forklift to realize the lifting and lowering of the mast 1 and the forks 2, thereby realizing the unloading and transportation of goods. It is worth noting that these are all prior art and are not part of the technical problem of easy adjustment that needs to be solved in this technical solution, so they will not be described in detail.

[0026] Furthermore, when the user needs to adjust the distance between the forks 2 on both sides of the mast 1, he / she only needs to rotate the screw 42 by turning the knob, thereby driving the pressure plate 4 to move upward by rotating the screw 42.

[0027] When the pressure plate 4 moves to the top, the user can pull the locking pin 23 upwards. When the locking pin 23 moves to the top, the side cavities 24 on the locking pin 23 are all aligned with the locking cavity 32. At this time, the locking pin 23 is no longer locked to the locking cavity 32, and the user can control the fork 2 and the fixed pin 20 to move laterally. When the user adjusts the fixed pin 20 to the appropriate position, simply press the locking pin 23 downwards to make the locking pin 23 re-lock into the locking cavity 32, thereby fixing the fork 2 and the fixed pin 20 again. Finally, simply move the pressure plate 4 downwards via the screw 42 so that the pressure plate 4 presses against the top of the locking pin 23.

[0028] Furthermore, the support rod 3 has multiple locking cavities 32 adapted to the locking pin 23. Users can lock the locking pin 23 into different locking cavities 32 to fix the fork 2 in different positions, thereby achieving adjustment and fixation of the fork 2.

[0029] In this invention, by locking the locking pin 23 in different locking cavities 32 and pressing and fixing the locking pin 23 with the pressure plate 4, the fork 2 can be fixed in different positions, thereby realizing the adjustment of the distance between the forks 2 on both sides. The adjustment method in this device is simple and quick, and convenient for users to use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
