Description

Technical Field

[0001] This utility model relates to the field of coal mining and heavy machinery handling technology, specifically to a lifting device for the middle trough of a transport machine. Background Technology

[0002] In modern coal mining, the efficient installation of the fully mechanized longwall face is crucial for improving overall production efficiency. Among these components, the central trough of the conveyor, as a key component connecting and transporting coal, directly impacts the overall layout progress and safety of the longwall face. However, due to its irregular shape and significant weight, the central trough presents numerous challenges during lifting and handling.

[0003] Traditional lifting methods rely primarily on selecting appropriate lifting points and connecting them to the central channel via chains or wire ropes. However, due to the complex shape of the central channel, determining suitable lifting points is extremely difficult, and improper selection can easily lead to the risk of disengagement or falling during lifting, resulting in safety accidents. Furthermore, while hydraulically controlled robotic arms can achieve a degree of automation, the lack of effective fixing and stabilization mechanisms makes the central channel prone to swaying in the air, further increasing operational risks and affecting installation accuracy.

[0004] In view of the above, there is an urgent need for a specially designed lifting device that can not only ensure the stability of the central trough during lifting and prevent swaying and falling due to center of gravity shift, but also simplify the operation process, improve work efficiency, and ensure the safety of operators. Therefore, this utility model proposes a lifting device for the central trough of a transport machine to solve the above-mentioned defects in the prior art and meet the needs of actual production.

[0008] Furthermore, a wrench for lifting the crossbeam is inserted into the adjustment hole at the middle position of the lifting beam.

Detailed Implementation

[0016] The following combination Figure 1-2The contents of this utility model will be described in detail through specific embodiments. Example

[0017] The lifting device for the middle trough of the transport aircraft includes main components such as a clamping base 1, a clamping lever 2, a connecting rod 3, and a lifting beam 4. The clamping base 1 is made of high-strength alloy steel to ensure it will not deform or be damaged under high-load operating conditions. Symmetrically arranged on the left and right sides of the clamping base 1 are protrusions 101 connected to the clamping lever 2 via pins; these protrusions 101 have grooves 104 to ensure smooth movement of the clamping lever 2 and provide stable support. Symmetrically arranged on the left and right ends of the clamping base 1 are lower clamping parts 102, used to form a tight clamping structure with the clamping lever 2. A limiting part 103 is vertically arranged in the middle, which not only prevents the lifting beam 4 from moving forward, backward, left, or right, but also ensures balanced force during lifting.

[0018] The outer end of the clamping lever 2 is provided with an upper clamping part 201, which cooperates with the lower clamping part 102 to form a concave structure for firmly clamping the upper edges of both sides of the central groove 7. This design effectively avoids the risk of the central groove falling off or swinging during lifting, greatly improving operational safety.

[0019] The two ends of the connecting rod 3 are hinged to the inner end of the clamping lever 2 and the outer end of the lifting beam 4 respectively through pins, which makes the whole device flexible.

[0020] The lower part of the lifting beam 4 is provided with an insertion part 401, which is movably inserted into the groove of the limiting part 103, ensuring the positioning accuracy and stability of the lifting beam 4. Several adjustment holes 402 are arranged horizontally at intervals on the upper part of the lifting beam 4 for fixing the shackles 6. This allows for flexible adjustment of the shackle position according to different lifting needs, improving ease of use and adaptability. Furthermore, a wrench 5 is inserted into the adjustment hole in the middle of the lifting beam, facilitating manual adjustment by the operator and simplifying the lifting preparation process.

[0021] The usage process of this utility model:

[0022] Before use, connect the entire device to the lifting hook using shackle 6 and lifting chain. Place the lifting device on the central groove to be lifted, ensuring that the upper edges of both sides of the central groove are within the concave structure between the clamping lever 2 and the clamping base 1. Then, use wrench 5 to lift the lifting beam 4, ensuring that the upper edges of both sides of the central groove are securely clamped. Next, during the lifting process, as the lifting hook is raised, the lifting beam 4 rises accordingly, and the connecting rod 3 drives the clamping lever 2 to rotate around the pin, thereby firmly clamping the central groove and ensuring that it is safely and smoothly lifted to the designated position.
