Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a material lifting device for asphalt concrete. Background Technology

[0002] In the production of asphalt concrete, material lifting is a crucial step. Traditional material lifting methods mostly rely on manual operation, which is not only inefficient and labor-intensive but also prone to human error, thus affecting production progress. For example, when manually handling materials, worker fatigue or improper operation may cause material spillage, affecting the production environment and wasting materials.

[0003] While some existing lifting equipment has improved efficiency to a certain extent, it also has many problems. Some equipment has a complex structure and high installation and maintenance costs, which are difficult for some small businesses to afford.

[0004] Therefore, developing a high-efficiency, low-cost, and highly automated material lifting device for asphalt concrete is of great practical significance in order to address the shortcomings of existing technologies and meet the growing production demands. Utility Model Content

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a material lifting device for asphalt concrete.

[0026] In this embodiment, refer to Figure 1-4 The asphalt concrete material lifting device includes a movable base 1, a material frame 2 for holding materials, a feeding tray 4 mounted on the movable base via a column 3, a vertical frame 5 mounted on the movable base, a lifting mechanism mounted on the vertical frame, a lifting tray 6 mounted parallel to the feeding tray, and a feeding moving module 7 and a discharging moving module 8 respectively mounted below the feeding tray and the lifting tray. Both sides of the feeding tray and the lifting tray are provided with a pushing groove 9. The output end of the feeding moving module is connected to a feeding push rod 10, and the output end of the discharging moving module is connected to a discharging push rod 11.

[0027] In the above technical solution, the mobile base provides mobility, making it convenient to flexibly deploy the device in different work sites; the material frame is used to hold materials; the feeding tray and the lifting tray are responsible for feeding and lifting the material frame, respectively; the lifting mechanism realizes the vertical lifting of materials; the feeding moving module and the discharging moving module, together with the pusher and push rod, realize the automatic feeding and discharging of the material frame. The cooperation of each component lays the foundation for realizing the automated and efficient lifting and conveying of materials.

[0028] The specific operating principle is as follows:

[0029] 1. Preparation stage: First, load the material into the material frame and place the material frame on the feeding tray.

[0030] 2. Feeding Stage: The material-filled frame is placed on the feeding tray. The frame limiting plates on both sides of the feeding tray limit the frame's position, ensuring accurate positioning. At this point, the feeding moving module is activated, with the pushing cylinder acting as the power source, driving the feeding push rod to slide along the pushing groove. Because the surface of the feeding tray is equipped with movable ball bearings, the friction between the frame and the tray is greatly reduced, allowing the feeding push rod to easily and smoothly push the frame towards the lifting tray.

[0031] 3. Lifting Stage: Once the material frame reaches the lifting pallet, the lifting mechanism is activated. The lifting motor is powered on and runs, driving the pulley to rotate via the drive shaft, which in turn drives the lifting belt to move, causing the lifting pallet connected to the lifting belt to rise accordingly.

[0032] 4. Discharge Stage: Once the lifting pallet reaches the designated height, the discharge moving module is activated. The discharge push rod is pushed by the push cylinder, sliding along the push grooves on both sides of the lifting pallet to push the material frame off the lifting pallet, completing the discharge operation and achieving efficient material lifting and conveying.

[0033] Specifically, the movable base includes a base plate 12 and omnidirectional casters 13 fixed on the base plate.

[0034] In this embodiment, omnidirectional casters are provided on the mobile base to facilitate the movement of the device.

[0035] Specifically, the surfaces of the feeding tray and the lifting tray are equipped with movable ball bearings 14.

[0036] In this embodiment, movable ball bearings are installed on the surfaces of the feeding tray and the lifting tray, which effectively reduces the friction between the material frame and the tray. During the process of the feeding push rod pushing the material frame from the feeding tray to the lifting tray, and the discharging push rod pushing the material frame out of the lifting tray, the movable ball bearings make the movement of the material frame smoother, reduce the power required for pushing the material, and also reduce the wear of the material frame and the tray, thus extending the service life of the equipment.

[0037] Specifically, the lifting mechanism includes a mounting plate 15 fixed on a vertical frame, bearing seats 16 fixed at both ends of the mounting plate 15, pulleys 17 connected to the bearing seats, lifting belts 18 connected to the pulleys at both ends, a drive shaft 19 connected to the bearing seats at the bottom of the mounting plate, and a lifting motor 20 driven by the drive shaft. The lifting support plate is connected to the lifting belt.

[0038] In this embodiment, the lifting mechanism adopts a combined design of mounting plate, bearing seat, pulley, lifting belt, drive shaft, and lifting motor, resulting in a compact structure and stable transmission. The lifting motor drives the pulley to rotate via the drive shaft, which in turn drives the lifting belt to achieve smooth lifting and lowering of the lifting pallet. This structure can precisely control the height of the lifting pallet, meeting the material lifting height requirements under different working conditions, and also features low operating noise and low energy consumption, improving the overall performance and stability of the equipment.

[0039] Specifically, both the feeding moving module and the discharging moving module include two upright plates 21 and a pushing cylinder 22 fixed between the two upright plates 21.

[0040] In this embodiment, the feeding moving module and the discharging moving module adopt a structure of two vertical plates and a pushing cylinder. The pushing cylinder serves as a power source to drive the feeding push rod and the discharging push rod.

[0041] Specifically, the feeding tray is provided with material frame limiting plates 23 on both sides.

[0042] In this embodiment, material frame limiting plates are provided on both sides of the feeding tray to limit the material frame placed on the feeding tray. This ensures the accurate positioning of the material frame during the feeding process, prevents the material frame from shifting on the feeding tray, and ensures that the feeding push rod can smoothly push the material frame to the lifting tray, thereby improving the accuracy and stability of material conveying and reducing feeding failures caused by material frame position deviation.

[0043] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
