Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, specifically a forklift hoisting equipment designed to prevent detachment. Background Technology

[0002] In current forklift lifting operations, a set of circular lifting ropes is typically used to suspend the uppermost set of axles on the forklift carriage. During lifting, the workpiece changes from a horizontal to an vertical position. It is necessary to press the lifting ropes inwards by hand to prevent them from slipping during the lifting process. Care must be taken to avoid collisions between the workpiece and the lifting ropes during transport to prevent the ropes from slipping. If the workpiece is misaligned and needs to be corrected during re-lifting, care must be taken to prevent the lifting ropes from slipping.

[0003] The existing hoisting method has safety hazards. The shaft at the suspension point is a bare shaft, which cannot function as a limiter for the hoisting rope, making it prone to detachment. The operation requires using an overhead crane to hang the workpiece on the rack; if the workpiece collides with the rack or is repositioned during transport, it is even more likely to fall. Furthermore, the operation usually requires manual assistance, with personnel standing near the workpiece, which is highly dangerous. Utility Model Content

[0004] The purpose of this utility model is to provide a forklift lifting device that prevents detachment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A forklift lifting device for preventing detachment includes a bushing, a vertical connecting plate on one side of the bushing, a lifting ring mounting plate on the side of the vertical connecting plate away from the bushing, and an anti-detachment device on the vertical connecting plate, the anti-detachment device including a limiting plate located outside the lifting ring mounting plate.

[0007] As a further embodiment of this utility model: the bushing is sleeved on the fork shaft.

[0008] As a further embodiment of this utility model: the lifting ring mounting plate is provided with mounting holes for connecting lifting equipment, and the width of the mounting holes is not greater than the width of the bushing.

[0009] As a further embodiment of this utility model: the anti-detachment device includes a transverse connecting plate located on one side of the vertical connecting plate, the transverse connecting plate being arranged along the axial direction of the bushing, and the limiting plate being fixedly connected to the end of the transverse connecting plate away from the vertical connecting plate.

[0010] As a further embodiment of this utility model, the distance between the limiting plate and the vertical connecting plate is not less than the thickness of the forklift crossbeam.

[0011] As a further embodiment of this utility model: the distance between the limiting plate and the vertical connecting plate is not greater than the sum of the thickness of the fork carriage crossbeam and the thickness of the bushing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During the hoisting process, the lifting device automatically locks due to gravity when it is lifted to a vertical position, eliminating the need for manual locking. After the workpiece is hoisted, the lifting rope is loosened, and the lifting device automatically unlocks due to gravity. Compared with the original rope hoisting structure, it is more stable and reliable. Even if the workpiece collidees with the material rack during the hoisting process, the tension of the lifting rope changes, or the hoisting is incorrect and requires re-hoisting, there will be no problem of detachment, improving safety performance and effectively increasing work efficiency. At the same time, the lifting device of this application has a simple structure, is easy to use, and has low cost. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 In this embodiment of the utility model, a fork carriage lifting device that prevents detachment includes a bushing 1. The bushing has a circular structure and is sleeved on the fork shaft head 6, thereby facilitating the connection between the lifting device and the fork carriage.

[0019] A vertical connecting plate 2 is provided on one side of the bushing 1, and a lifting ring mounting plate 3 is provided on the side of the vertical connecting plate 2 away from the bushing 1. The lifting ring mounting plate 3 is provided with mounting holes for connecting lifting equipment. The width of the mounting holes is not greater than the width of the bushing 1 to ensure stability during lifting.

[0020] An anti-detachment device is provided on the vertical connecting plate 2. The anti-detachment device includes a horizontal connecting plate 4 and a limiting plate 5. The horizontal connecting plate 4 is fixedly connected to one side of the vertical connecting plate 2 and is arranged along the axial direction of the bushing 1. The limiting plate 5 is fixedly connected to the end of the horizontal connecting plate 4 away from the vertical connecting plate 2. The limiting plate 5 is located outside the lifting ring mounting plate 3. Furthermore, the distance between the limiting plate 5 and the vertical connecting plate 2 is not less than the thickness of the fork carriage crossbeam, and the distance between the limiting plate 5 and the vertical connecting plate 2 is not greater than the sum of the thickness of the fork carriage crossbeam and the thickness of the bushing 1. This ensures that during the lifting process, the limiting plate 5 can smoothly engage with the other side of the fork carriage crossbeam 7, and also prevents the bushing 1 from falling off the fork carriage shaft head 6 when the limiting plate 5 engages with the other side of the fork carriage crossbeam 7.

[0021] In the initial state, such as Figure 2 As shown, the fork carriage is in a horizontal state at this time. The bushing 1 of this embodiment is fitted onto the fork shaft head 6. At this time, the transverse connecting plate 4 is pressed against the upper end of the fork carriage crossbeam 7. Looking from the axial direction of the bushing 1, the limiting plate 5 has not entered behind the fork carriage crossbeam 7. Then, the lifting equipment is connected to the lifting hole on the lifting ring mounting plate 3, and the lifting equipment is started to lift the fork carriage. During the lifting process, as the lifting device rises, one end of the fork carriage will rise with the lifting device, while the other end remains on the production line. That is, the bushing 1 and the fork carriage bushing 6 rotate relative to each other. During this rotation, the limiting plate 5 gradually rotates to the rear of the fork carriage crossbeam 7. When the fork carriage is completely lifted, as shown... Figure 3 As shown, at this time, the limiting plate 5 is located behind the fork carriage crossbeam 7. The limiting plate 5 allows the bushing 1 to move axially on the fork carriage bushing 6, effectively preventing the fork carriage from falling off during the hoisting process.
