Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoist technology, specifically to a hoist material carrying structure that prevents displacement. Background Technology
[0002] Forklifts are industrial handling vehicles capable of loading, unloading, stacking, and short-distance transport of palletized goods. They consist of a vehicle and a lifting mechanism. In the lifting mechanism, the two forks serve as the loading area. By placing goods on top of the forks, and then cooperating with the vehicle's movement and the lifting mechanism's own lifting function, loading and unloading operations are carried out. In actual operation, when transporting some relatively large but lightweight goods, if the vehicle encounters bumps during travel, the goods placed on the forks may shift or sway from side to side. Utility Model Content
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a lifting machine loading structure to prevent displacement, so as to solve the problem mentioned in the background art that when the vehicle encounters bumps during travel, the relatively large but light goods on the forks of the lifting machine as the loading structure are prone to displacement or swaying from side to side, which affects the stability.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a lifting machine material-carrying structure for preventing displacement, comprising a fork plate and two parallel hanging plates slidably engaged with the top of the fork plate. The bottom of each of the two hanging plates is integrally formed with a support frame. The bottom of each of the two support frames on opposite sides is provided with a groove. The inner wall of the groove is equipped with an L-shaped side limiting component. The back of each of the two hanging plates is fixedly installed with a connecting block. Hydraulic cylinders are fixedly installed on the inner walls of both sides of the fork plate, and the free ends of the two hydraulic cylinders are respectively attached to the outer surfaces of the two connecting blocks. The two hydraulic cylinders are arranged in a staggered manner.
[0005] Preferably, the side limiting assembly includes two T-shaped columns arranged front to back and fixedly installed on the top wall of the groove. The outer surfaces of the two T-shaped columns are rotatably fitted with side pull plates, and the two side pull plates are fitted with limiting baffles arranged in an L-shape.
[0006] Preferably, each of the two side pull plates has several circular grooves arranged side by side on opposite sides, and the front and back of the limiting baffle have insertion grooves. A spring is connected inside the circular groove, and one end of the spring is connected to a snap-fit post extending into the insertion groove. Magnetic plates are fixedly fitted on opposite sides of the two side pull plates.
[0007] Preferably, a reinforcing plate arranged in a π-shape and located below the hydraulic cylinder is welded between the inner walls of both sides of the fork plate, and the bottom of the reinforcing plate is fixedly connected to the bottom wall of the fork plate.
[0008] Preferably, the pallet frame consists of a front part, a middle part, and a rear part. The width of the front part gradually decreases from front to back, and the thickness of the front part, middle part, and rear part of the pallet frame increases sequentially, with the overall bottom being arc-shaped.
[0009] Preferably, a multi-section telescopic sleeve is fixedly installed between the two opposite sides of the pallet frame, and the multi-section telescopic sleeve is located in the middle of the pallet frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. In this utility model, the distance between the two structures consisting of a lifting plate and a pallet frame is controlled by the extension and retraction of two hydraulic cylinders, so that it is adapted to the width of the goods. In addition, after the goods are placed on the two pallet frames, the two hydraulic cylinders are used to retract, controlling the two lifting plates to drive their respective structures to retract the distance, so that the two side limiting components clamp the two sides of the goods, preventing the goods from swaying or shifting from side to side during the forklift's movement.
[0012] 2. In this utility model, by squeezing the snap-fit post, the spring contracts and disengages from the insertion slot. Then, by applying a pulling action, the limiting baffle and the side pull plate can be separated, making the side limiting component easy to remove from the tray frame. This allows the user to choose whether to install or replace it according to actual needs. 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] To address the issue that existing hoists, when encountering bumps during vehicle movement, can cause relatively large but lightweight loads on the forks (which act as the load-bearing structure) to shift or sway, affecting stability, please refer to [the relevant documentation / reference]. Figures 1-3 One embodiment provided by this utility model:
[0019] A lifting hoist loading structure for preventing displacement includes a fork plate 1 and two parallel hanging plates 2 that are slidably engaged with the top of the fork plate 1. The bottom of each hanging plate 2 is integrally formed with a pallet frame 3. The bottom of each pallet frame 3 on opposite sides is provided with a groove 301. The inner wall of the groove 301 is fitted with an L-shaped side limiting component 4. The back of each hanging plate 2 is fixedly installed with a connecting block. Hydraulic cylinders 101 are fixedly installed on the inner walls of both sides of the fork plate 1. The free ends of the two hydraulic cylinders 101 are respectively attached to the outer surfaces of the two connecting blocks. The two hydraulic cylinders 101 are staggered. The pallet frame 3 is composed of a front part, a middle part and a rear part. The width of the front part gradually decreases from front to back. The thickness of the front part, the middle part and the rear part of the pallet frame 3 increases sequentially and the bottom of the whole is arc-shaped.
[0020] This structure, as part of the forklift lifting mechanism, is combined with the lifting mechanism via a fork plate 1. The fork plate 1, together with two lifting plates 2 and two pallet frames 3, forms a loading area. In actual use, two hydraulic cylinders 101 are operated according to the width of the goods to be transported, causing them to extend outward. This generates a pushing force in opposite directions on the two connecting blocks, gradually increasing the distance between the two lifting plates 2. Eventually, the distance between the opposite sides of the two side limiting components 4 is greater than the width of the goods. When the goods are forked onto the two pallet frames 3, the two hydraulic cylinders 101 are operated again to retract inward, controlling the two lifting plates 2 to retract the distance between their respective structures. This allows the two side limiting components 4 to clamp the sides of the goods, preventing the goods from swaying or shifting during forklift movement. In addition, when the forklift is not in use, the two hydraulic cylinders 101 can be adjusted to a retracted state to prevent the distance between the two side limiting components 4 from exceeding the width of the forklift. The shape of the pallet frames 3 can effectively assist in inserting them under the goods.
[0021] Please see Figure 2 and Figure 3 One embodiment provided by this utility model:
[0022] The side limiting assembly 4 includes two T-shaped posts 401 arranged front to back, which are fixedly installed on the top wall of the groove 301. The outer surfaces of the two T-shaped posts 401 are rotatably fitted with side pull plates 402. The two side pull plates 402 are fitted with L-shaped limiting baffles 403. Several circular grooves are opened on the opposite side of the two side pull plates 402. The front and back of the limiting baffles 403 are opened with insertion grooves 404. A spring 405 is connected inside the circular groove. One end of the spring 405 is connected to a snap-fit post 406 that extends into the insertion groove 404. Magnetic suction pieces 407 are fixedly fitted on the opposite side of the two side pull plates 402.
[0023] Based on the previous embodiment, the side limiting component 4 in this structure can be easily disassembled, which allows users to choose whether to install or replace it according to actual needs. By squeezing the locking post 406, the spring 405 contracts and disengages from the insertion slot 404, adjusting the locking post 406 to be flush with the side of the side pull plate 402. At this time, the limiting baffle 403 and the side pull plate 402 can be separated by pulling. Then, the side pull plate 402 is moved, and the side pull plate 402 is more firmly stored in the space of the groove 301 by using the property of the magnetic piece 407 and the iron tray 3 to attract each other.
[0024] like Figure 1 As shown, a reinforcing plate 102 arranged in a π shape and located below the hydraulic cylinder 101 is welded between the inner walls of both sides of the fork plate 1. The bottom of the reinforcing plate 102 is fixedly connected to the bottom wall of the fork plate 1. Multiple telescopic sleeves 5 are fixedly installed between the opposite sides of the two pallet frames 3, and the multiple telescopic sleeves 5 are located in the middle of the pallet frame 3.
[0025] The reinforcing plate 102 can enhance the structural strength of the forklift plate 1. The multi-section telescopic sleeve 5 is located at the front of the pallet frame 3, which can effectively prevent debris on the ground from entering under the goods placed on the pallet frame 3, and its length is adjusted accordingly as the distance between the two pallet frames 3 changes.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
