Description

Technical Field

[0001] This utility model relates to the field of automated conveying equipment technology, specifically a two-stage lifting and positioning mechanism for a double-speed chain conveyor. Background Technology

[0002] In the context of modern industrial production, high-speed chain conveyor systems, with their superior efficiency and stable material handling capabilities, have been widely used in various assembly and processing production lines. This system is a crucial link in modern industrial production processes, playing an indispensable role in improving production efficiency and ensuring product quality.

[0003] Traditional related devices typically employ a single-stage lifting structure. This structure reveals numerous drawbacks in practical applications, particularly in achieving precise height adjustments to tooling plates or workpieces. This is because the single-stage lifting structure has inherent design limitations; it lacks a more complex and precise adjustment mechanism, thus often proving inadequate for tasks requiring precise height adjustments.

[0004] Traditional lifting devices suffer from another serious problem during operation. Because they often rely solely on a single cylinder for lifting or lack effective synchronization mechanisms in their overall design, the lifting platform is prone to tilting or swaying. This can disrupt the entire production process, potentially causing interruptions or inaccuracies in material transport. Reduced reliability means the equipment is more susceptible to various problems during long-term operation. As usage time increases, the hidden dangers caused by tilting or swaying of the lifting platform gradually accumulate, potentially leading to equipment failure and impacting the normal operation of the entire production line, resulting in production delays, increased costs, and other adverse consequences for the company.

[0010] Preferably, the limiting block on the primary lifting module is connected to the limiting guide rail, and the transmission chain is pulled up by the lifting of the hydraulic device, thereby driving the pallet to rise and fall.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This two-stage lifting and positioning mechanism of the double-speed chain conveyor features a hydraulic system providing significant lifting force, suitable for lifting heavy objects. The chain disc and transmission chain ensure reliable transmission, while limit blocks and support rods on both sides of the chain enhance stability. The limit blocks, connected to limit guide rails, precisely control the lifting trajectory of the pallet, ensuring smooth and accurate operation. In the secondary lifting module, a receiving plate is mounted on the support plate of the connecting block.

[0018] 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.

[0019] Example: Please refer to Figure 1 This utility model provides a technical solution: a two-stage lifting and positioning mechanism for a double-speed chain, including a main body 1, a limiting guide rail 2 installed on the main body 1, a first-stage lifting module 3 installed on the limiting guide rail 2, and a second-stage lifting module 4 installed on the first-stage lifting module 3.

[0020] The first-stage lifting module 3 includes a fixed base 5, a fixed seat 12 is installed on the fixed base 5, a hydraulic device 8 is installed above the fixed seat 12, a chain 10 is installed above the hydraulic device 8, a transmission chain 11 is installed on the chain 10, limit blocks 6 are installed on both sides of the transmission chain 11, support rods 9 are installed on the limit blocks 6, and a support plate 7 is installed in front of the limit blocks 6.

[0021] Among them, the limit block 6 on the first-level lifting module 3 is connected to the limit guide rail 2, and the transmission chain 11 is pulled up by the lifting of the hydraulic device 8, thereby driving the pallet 7 to rise and fall.

[0022] In this embodiment, a solid foundation for the stability of the entire module is established. A hydraulic device is installed above it, providing a considerable lifting force as a power source. The chain track, located above the hydraulic device, works in conjunction with the drive chain, a transmission method characterized by high reliability. A limit block is connected to a limit guide rail; this connection method precisely controls the lifting trajectory of the pallet, ensuring accuracy during lifting and making the entire lifting operation smoother. This effectively avoids potential equipment damage or material spillage due to shaking.

[0023] The secondary lifting module 4 includes a connecting block 13, a support plate 14 mounted on the connecting block 13, a receiving plate 15 mounted on the support plate 14, an installation hole 17 on the receiving plate 15, a positioning pin 16 mounted on the installation hole 17, a limit post 19 mounted at the lower end of the receiving plate 15, and a lifting device 18 mounted on the left side of the limit post 19.

[0024] The lifting device 18 includes a pneumatic motor 20, with an air supply pipe 21 installed at the right end of the pneumatic motor 20. A pressure device 22 is installed on the air supply pipe 21, a top column 23 is installed on the left side of the pressure device 22, and a slider 24 is installed on the left side of the top column 23. A roller 25 is installed above the slider 24, and a support block 26 is installed above the roller 25.

[0025] In this embodiment, the receiving plate is easily connected to or positioned with other components. It can be accurately fixed in position, ensuring the continuity and accuracy of material transport. A limit post is installed at the lower end of the receiving plate to prevent excessive descent and damage to the equipment or collision with other components. The lifting device is also an important component of the secondary lifting module. It is powered by a pneumatic compressor, which transmits the power to the pressure device through an air supply pipe. Compared to a hydraulic system, it eliminates the problem of oil leakage. The pressure device effectively converts the pneumatic power generated by the compressor into lifting force, and the cooperation of the slider, roller, and support block makes the lifting process smoother, greatly reducing the impact of friction on lifting efficiency.

[0026] Working principle: In actual operation, the first step is to catch the material using the positioning pin 16 on the receiving plate 15. This ensures that the material falls accurately onto the receiving plate 15.

[0027] After the material is received, the primary lifting module 3 starts working. This primary lifting module 3 is a crucial component of the entire lifting system. Specifically, it uses a hydraulic device 8 to lift the chain wheel 10. The hydraulic device 8 has a powerful output capability, providing a stable lifting force to the chain wheel 10. When the chain wheel 10 is lifted, the drive chain 11, under the upward force of the chain wheel 10, drives the limit block 6 to rise along the limit guide rail 2. The limit guide rail 2 provides a fixed track for the rise of the limit block 6, ensuring the accuracy of its upward direction. The rise of the limit block 6 further drives the pallet 7 to rise, and the pallet 7 rises smoothly along with the limit block 6 during this process.

[0028] Subsequently, after the primary lifting module 3 reaches a certain height, the secondary lifting module 4 begins operation. The secondary lifting module 4 plays a unique role in the entire lifting process. Specifically, it works by using a pneumatic motor 20 to provide pressure to the pressure device 22. Upon receiving pressure, the pressure device 22's top column 23 is pushed, causing the slider 24 to move to the left. The slider 24 slides to the left under the push of the top column 23; this sliding process is crucial. As the slider 24 moves to the left, the roller 25 connected to it moves upward. The upward movement of the roller 25 then drives the support block 26, ultimately lifting the receiving plate 15 to the correct position via the support block 26.
