Description

Technical Field

[0001] The present invention relates to the field of logistics teaching, and particularly to a somatosensory interaction device for logistics simulation teaching. Background Art

[0002] The modern logistics management major faces the practical difficulties of "high costs, high risks, and high losses" in practical teaching. "High costs" means that modern logistics equipment is expensive, and the cost of teaching scenarios is high and difficult to build; "high risks" means that there are safety risks in the use of modern logistics mechanized equipment, and various problems will occur during actual operation, affecting teaching safety; "high losses" means that modern logistics equipment faces high loss problems during use, such as high energy consumption, large losses, many consumables, and high operating costs of power equipment, refrigeration equipment, and warehousing equipment. "Three difficulties": First, it is difficult to implement. Because large logistics enterprises have strict management and high standardization of operation processes, the number of students that can be absorbed is very small. And because it involves enterprise business secrets, it cannot be retained through shooting or other means in reality; second, it is difficult to reproduce. That is, it is difficult to build the operation sites and real equipment of large logistics enterprises on campus. In reality, large logistics enterprises rarely open such dangerous operation positions, and forklift operations within the enterprise require certificates. It is very difficult for students to truly experience the relevant operation standards and professional operations of large logistics enterprises in reality; third, it is difficult to observe. That is, in reality, in-warehouse operations are closed environment operations, and it is very difficult to open them to students on a large scale for observation.

[0003] Forklift teaching is an extremely important part of logistics management teaching. The weight of the goods lifted by the forklift during work is large, and there are relatively large safety hazards in actual operation. During the actual teaching process, in order to control teaching risks, it is generally difficult for students to personally experience the working body feeling under high load, such as forklift: tipping up, overloading, etc. This has an adverse impact on enhancing students' safety awareness and hidden danger awareness. Therefore, how to enable students to actually experience the operation feeling of the forklift under different loading loads through the operation of the forklift in the learning process through a certain form, and at the same time avoid the safety hazards brought by high weight loads to the greatest extent is an extremely important issue in forklift logistics teaching. Summary of the Invention

[0004] The purpose of the present invention is to provide a somatosensory interaction device for logistics simulation teaching with high safety and capable of realizing load simulation.

[0005] To achieve the above invention purpose, the technical solution adopted by the present invention is: A somatosensory interaction device for logistics simulation teaching, including a mounting frame, a tray arranged in the mounting frame, and a counterweight mechanism for applying a load to the tray;

[0006] The mounting bracket includes two opposing vertical columns on the left and right. The tray is arranged between the two opposing vertical columns. A chute is provided on the side of the vertical column facing the tray, and a slider that forms a sliding fit with the chute is provided on the tray.

[0007] A foundation pit is dug between the two vertical columns on the side of the mounting bracket, and the counterweight mechanism is installed in the foundation pit. Side pulleys are provided on the side walls of the tray. The counterweight mechanism includes a counterweight steel rope and a base fixed to the bottom of the foundation pit. A driving cylinder and a rope-passing cylinder are provided on the top of the base. One end of the counterweight steel rope passes through the rope-passing cylinder and is fixedly arranged on the base, and the other end bypasses the side pulley and is connected to a counterweight assembly installed in the driving cylinder.

[0008] Preferably, the counterweight assembly includes a magnetic counterweight block arranged in the driving cylinder, and two electromagnetic force-enhancing blocks fixedly arranged at the upper and lower ends of the driving cylinder. The magnetic counterweight block is connected to the counterweight steel rope, and the polarity of the lower electromagnetic force-enhancing block is opposite to that of the magnetic counterweight block, and the polarity of the upper electromagnetic force-enhancing block is the same as that of the magnetic counterweight block.

[0009] Preferably, the counterweight mechanism further includes a force-amplifying assembly. The force-amplifying assembly includes a force-amplifying steel rope and a force-amplifying pulley. The force-amplifying pulley is fixedly arranged at one end of the counterweight steel rope opposite to the magnetic counterweight block. One end of the force-amplifying steel rope passes through the rope-passing cylinder and is fixedly arranged on the base, and the other end bypasses the force-amplifying pulley and enters the driving cylinder to be connected to the magnetic counterweight block.

[0010] Preferably, the base includes a column body. A plurality of annular embedded rings are uniformly arranged along the vertical direction on the side wall of the column body, and pouring holes are provided on the embedded rings. The base is fixed to the bottom of the foundation pit by concrete pouring.

[0011] Preferably, two sets of counterweight mechanisms are symmetrically arranged on the left and right sides of the tray.

[0012] Preferably, the tops of the vertical columns are connected by a cross beam to form a square frame structure. The vertical columns and the cross beam are both made of I-beams.

[0013] Preferably, supporting pads are provided at the bottoms of the front and rear sides of the tray. The supporting pads are stacked by a plurality of strip-shaped rubber bodies.

[0014] Preferably, the tray includes two U-shaped steel channels arranged side by side and extending in the front-rear direction with openings facing downwards, and a plurality of square steels welded side by side on the tops of the two steel channels.

[0015] The beneficial effects of the present invention are mainly reflected in: it can simulate the counterweight in forklift operation, facilitating trainees to personally experience the forklift operation feeling under high counterweight, simulating the operation physical feeling feedback to the forklift under high counterweight, effectively improving the intuitiveness of forklift teaching, while reducing the risks brought by high counterweight in forklift teaching and ensuring teaching safety. Specifically, during the working process of the present invention, the teacher first adjusts the counterweight parameters of the counterweight mechanism for the pallet as needed. The trainee operates the forklift fork arm to extend into the bottom of the pallet to lift the pallet. During the lifting process, due to the downward pulling force exerted by the counterweight mechanism on the pallet through the counterweight steel rope, the cargo counterweight on the pallet is simulated. Based on the forklift operation experience of the trainee and the intuitive physical feeling brought by the reaction force feedback from the pallet to the forklift, the trainee can effectively understand the key points and precautions during the forklift operation process, providing a strong guarantee for improving the forklift teaching effect. At the same time, since the present invention uses a counterweight mechanism to simulate the pallet counterweight, there is no need to actually stack goods on the pallet, eliminating risks such as tipping and collapse, greatly improving the teaching safety, and is especially suitable for use in the primary early practical teaching of forklifts. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic structural diagram of the present invention;

[0017] Figure 2 is Figure 1 the enlarged view of part A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Combined with Figure 1-2 as shown, a somatosensory interaction device for logistics simulation teaching is mainly applied in logistics management teaching to train trainees in forklift operation, and is especially suitable for safe operation practice teaching during the initial training period. It solves the practical problems of large counterweight, high risk and inconvenient adjustment of counterweight existing in traditional practical teaching, enabling trainees to personally experience the somatosensory feedback under high counterweight in forklift operation, and has the characteristics of good teaching effect and high safety.

[0019] As Figure 1 shown in

[0020] The mounting bracket of the present invention serves as the mounting foundation for the pallet 0. It limits the pallet 0 in the up-down, left-right, and front-back directions, allowing only the up-down movement of the pallet 0 to meet the needs of primary forklift teaching. As Figure 1 shown in the figure, the mounting bracket includes two pairs of opposing columns 1. That is to say, a total of 4 columns 1 are provided, with two of them as a pair, respectively located on the left and right sides of the pallet 0 (that is, Figure 1 the front and back sides in the perspective of the figure), and the pallet 0 is arranged between the two pairs of columns 1. To further improve the integrity and structural strength of the mounting bracket, the tops of the columns 1 are connected by a crossbeam 14 to form a square structure. The columns 1 and the crossbeam 14 are generally made of I-beams.

[0021] A chute is arranged on the side of the column 1 facing the pallet 0, and a slider that forms a sliding fit with the chute is arranged on the pallet 0. The simplest chute can be directly formed by the side groove of the I-beam, and the slider can be formed by welding a cylindrical block or a square block that matches the side groove of the I-beam on the side wall of the U-shaped channel steel of the pallet 0. Among them, the cylindrical block has better sliding smoothness.

[0022] Considering that during the process of the pallet 0 being lifted and then lowered, to avoid the pallet 0 hitting the ground too quickly due to improper operation, the present invention can set sleepers between the columns 1, or can be provided with supporting pads 15 at the bottom of the front and back sides of the pallet 0. The supporting pads 15 are stacked by a number of strip-shaped rubber bodies. Compared with the sleepers, the overall cushioning performance of the supporting pads 15 is better, which can effectively avoid the falling impact.

[0023] As the core structure for simulating the counterweight of the pallet 0 in the present invention, the counterweight mechanism of the present invention adopts the following design: A foundation pit 2 is dug between the two columns 1 on the side of the mounting bracket. On the one hand, the foundation pit 2 serves as the installation pit for the counterweight mechanism, and on the other hand, it serves as the maintenance pit for the counterweight mechanism. The counterweight mechanism is installed in the foundation pit 2. To ensure the balanced force on both sides of the pallet 0, usually two groups of counterweight mechanisms are symmetrically arranged on the left and right sides of the pallet 0.

[0024] On the side wall of the tray 0, side pulleys 3 are provided. The side pulleys 3 serve as transition components of the counterweight mechanism that directly transmit the counterweight force towards the tray 0. The axle of the side pulley requires reliable welding, and reinforcement steel plates can be used to strengthen the axle part. The counterweight mechanism includes a counterweight steel rope 4 and a base 5 fixed at the bottom of the foundation pit 2. The base 5 serves as the fixed node of the entire counterweight mechanism and is required to have excellent installation and fixing stability. The base 5 includes a column 12. On the side wall of the column 12, a plurality of annular embedded rings 13 are uniformly arranged vertically. Pouring holes are provided on the embedded rings 13. The base 5 is fixed at the bottom of the foundation pit 2 by concrete pouring. During production, after excavating a groove for burying the base 5 at the bottom of the foundation pit, the base 5 (together with the driving cylinder 6 and the rope-passing cylinder 7 thereon) is placed into the foundation pit 2 as a whole. After tamping, it is covered with concrete pouring. The pouring holes can facilitate the flow of concrete and avoid air accumulation. After the concrete block is completely dry, the force-bearing parameters of the base 5 are detected. Only after meeting the requirements can the subsequent installation construction be carried out.

[0025] On the top of the base 5 of the present invention, a driving cylinder 6 and a rope-passing cylinder 7 are provided. One end of the counterweight steel rope 4 passes through the rope-passing cylinder 7 and is fixedly arranged on the base 5, and the other end bypasses the side pulley 3 and is connected to a counterweight assembly installed in the driving cylinder 6. There are many specific structures of the counterweight assembly. It amplifies the force through the counterweight steel rope 4 and applies it to the side pulley 3, and is conducted to the tray 0 through the side pulley 3 for counterweight simulation. The simplest counterweight assembly is a large-weight counterweight block, but in this way, the upper limit of the counterweight is restricted by its overall size and cannot be flexibly adjusted according to actual teaching needs.

[0026] Therefore, a better way in the present invention is that the counterweight assembly includes a magnetic counterweight block 8 arranged in the driving cylinder 6, and two electromagnetic force-enhancing blocks 9 fixedly arranged at the upper and lower ends of the driving cylinder 6. The magnetic counterweight block 8 is connected to the counterweight steel rope 4, and the polarity of the lower electromagnetic force-enhancing block 9 is opposite to that of the magnetic counterweight block 8, and the polarity of the upper electromagnetic force-enhancing block 9 is the same as that of the magnetic counterweight block 8. That is, simple counterweight can be carried out solely relying on the weight of the magnetic counterweight block 8, or magnetic repulsive force (at the bottom) and suction force (at the top) can be applied through the electromagnetic force-enhancing blocks 9. In this way, not only the size of the overall counterweight has the characteristic of being adjustable, but also through the real-time adjustment of the force output size parameters of the upper and lower two electromagnetic force-enhancing blocks 9, the output of the overall counterweight force can be made more stable, so that the counterweight force remains at the initial set level throughout the lifting process, avoiding counterweight fluctuations.

[0027] During the operation of the present invention, the teacher first adjusts the counterweight parameters of the counterweight mechanism for the tray 0 according to needs. The trainee operates the forklift fork arm to extend into the bottom of the tray 0 to lift the tray 0. During the lifting process, since the tray 0 is subjected to the downward pulling force applied by the counterweight mechanism through the counterweight steel rope 4, the weight of the goods on the tray 0 is simulated. Based on the operation experience of the forklift and the intuitive physical feeling brought by the reaction force feedback from the tray 0 to the forklift, the trainee can effectively understand the key points and precautions during the operation of the forklift, providing a strong guarantee for improving the teaching effect of the forklift. At the same time, since the present invention uses a counterweight mechanism to simulate the counterweight of the tray 0 and does not require stacking goods on the tray 0 in reality, there are no risks such as tipping and collapse, greatly improving the teaching safety, especially suitable for use in the primary early practical teaching of forklifts.

[0028] In addition, in order to further increase the counterweight upper limit of the present invention and reduce the volume of the counterweight mechanism, the counterweight mechanism further includes a force amplification component. The force amplification component includes a force amplification steel rope 10 and a force amplification pulley 11. The force amplification pulley 11 is fixedly arranged at the end of the counterweight steel rope 4 opposite to the magnetic counterweight block 8. One end of the force amplification steel rope 10 passes through the rope passing cylinder 7 and is fixedly arranged on the base 5, and the other end bypasses the force amplification pulley 11 and enters the driving cylinder 6 to be connected with the magnetic counterweight block 8. The force amplification steel rope 10 and the force amplification pulley 11 act as a movable pulley group to amplify the counterweight force twice, which can greatly increase the overall counterweight upper limit.
