Description

Technical Field

[0001] This utility model relates to the field of metal oil drum opening technology, specifically, to a high-sealing metal oil drum opening structure. Background Technology

[0002] Metal oil drums are containers primarily used for storing and transporting liquids. They are typically made of metal materials such as iron, aluminum, or stainless steel and are widely used for storing and transporting various liquids, including chemicals, paints, and solvents. The design of metal oil drums takes into account durability, sealing, and safety, ensuring that they can effectively protect the contents in various environments. When using metal oil drums, a lid-opening structure is required to complete the opening operation. In practice, they have advantages such as simple operation, stable structure, and good opening effect.

[0003] In existing opening structures, opening a metal oil drum requires the use of a metal blade for rotation. However, the position of the metal blade is fixed, and the diameter of the opening cannot be adjusted according to the actual size of the metal oil drum, thus reducing the applicability of the opening structure. At the same time, the metal oil drum has a large weight, making it cumbersome, time-consuming, and laborious to move the metal oil drum to the opening position, which reduces the practicality of this utility model.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a highly airtight metal oil drum opening structure, which has the following beneficial effects:

[0018] (1) This utility model is equipped with a concave frame. When using the high-sealing metal oil drum opening structure, the gantry frame can be moved to the high-sealing metal oil drum using four sets of first universal wheels. Then, the two sets of arc plates are moved in opposite directions. When multiple sets of balls contact the high-sealing metal oil drum, the four sets of mounting screws and four sets of mounting nuts are engaged with each other. The operator rotates the four sets of mounting nuts clockwise and counterclockwise by hand. When the four sets of mounting nuts are in close contact with the gantry frame, the first control panel is used to extend the first electric telescopic rod. At the same time, the self-locking forward and reverse motor is activated. The output end of the self-locking forward and reverse motor can drive the bidirectional screw lever to rotate. Since the bidirectional screw lever and the two sets of screw sleeves are engaged with each other, the rotating bidirectional screw lever can push the two sets of screw sleeves closer or further apart. When the gap length between the two sets of sleeve plates reaches the preset value, the self-locking forward and reverse motor is stopped using the first control panel. Then, the two sets of cutting blades are moved down. When the two sets of cutting blades are moved out of the two sets of built-in slots, the four sets of connecting screws and four sets of connecting nuts engage with each other. The operator rotates the four sets of connecting nuts clockwise by hand. When the four sets of connecting nuts contact the two sets of socket plates, the two sets of cutting blades are stably fixed. The two sets of cutting blades that have moved down can be inserted into the interior of the high-sealing metal oil drum. Then the gantry can be rotated. During this process, the two sets of cutting blades can cut off the cover plate of the high-sealing metal oil drum. After the cover plate is cut off, the first electric telescopic rod is shortened using the first control panel. Then the four sets of connecting nuts are rotated counterclockwise to move the two sets of cutting blades into the two sets of built-in slots. Then the four sets of connecting nuts are rotated clockwise again. When the four sets of connecting nuts contact the two sets of socket plates again, the two sets of cutting blades are stably fixed inside the two sets of built-in slots. Through the concave frame, it can be used to open the lids of metal oil drums of various sizes, improving the applicability of the high-sealing metal oil drum lid opening structure.

[0019] (2) This utility model is equipped with counterweights. According to the above operation, before the two sets of cutting blades open the lid, the first control panel is used to de-energize multiple sets of electromagnets. Then, multiple sets of iron counterweights can be moved. When multiple sets of arc-shaped brake pads contact the outer wall of the high-sealing metal oil drum, multiple sets of second control panels are used to shorten multiple sets of second electric telescopic rods. During this process, four sets of lifting plates gradually move into the interior of four sets of grooves. When multiple sets of brake pads contact the ground, friction can be used to ensure the stability of the high-sealing metal oil drum. Then, the lid opening operation can be performed. After the lid is opened, multiple sets of second electric telescopic rods are extended using multiple sets of second control panels. When four sets of second universal wheels on the same side support a set of counterweights on the same side, multiple sets of counterweights can be attached to multiple sets of electromagnets. Then, the first control panel is used to energize multiple sets of electromagnets to complete the connection of multiple sets of iron counterweights. With the counterweights, the lid opening operation can be achieved without moving the metal oil drum, which improves the usability of the high-sealing metal oil drum lid opening structure.

[0039] Working principle:

[0040] In actual use of the high-sealing metal oil drum opening structure, the gantry frame 1 can be moved to the high-sealing metal oil drum using four sets of first universal casters 22. Then, the two sets of arc-shaped plates 6 move in opposite directions. When multiple sets of ball bearings 9 contact the high-sealing metal oil drum, the four sets of mounting nuts 7 are threadedly engaged by two sets of mounting screws 5 and four sets of mounting nuts 7. The operator manually rotates the four sets of mounting nuts 7 clockwise and counterclockwise. When the four sets of mounting nuts 7 are in tight contact with the gantry frame 1, the first control panel extends the first electric telescopic rod 2, simultaneously activating the self-locking forward and reverse motor 20. The output of the self-locking forward and reverse motor 20 can drive the bidirectional lead lever 11 to rotate. Because the bidirectional lead lever 11 and the two sets of lead screw sleeves 12 are threadedly engaged, the rotating bidirectional lead lever 11 can push the two sets of lead screw sleeves 12. When the lever sleeves 12 move closer or further apart, and the gap between the two sets of connecting plates 13 reaches a preset value, the self-locking forward and reverse motor 20 is stopped using the first control panel. Then, the two sets of cutting blades 16 are lowered. When the two sets of cutting blades 16 are removed from the two sets of internal slots 15, the four sets of connecting screws 18 and four sets of connecting nuts 19 engage with each other. The operator manually rotates the four sets of connecting nuts 19 clockwise. When the four sets of connecting nuts 19 contact the two sets of connecting plates 13, the two sets of cutting blades 16 are stably fixed. The lowered two sets of cutting blades 16 can then be inserted into the interior of the high-sealing metal oil drum. The gantry frame 1 can then be rotated. During this process, the two sets of cutting blades 16 can cut off the cover plate of the high-sealing metal oil drum. After the cover plate is cut, the first... The control panel shortens the first electric telescopic rod 2. Then, rotating the four sets of connecting nuts 19 counterclockwise moves the two sets of cutting blades 16 into the two sets of internal grooves 15. Rotating the four sets of connecting nuts 19 clockwise again, when they contact the two sets of sleeve plates 13 again, the two sets of cutting blades 16 are stably fixed inside the two sets of internal grooves 15. The concave frame 4 allows for opening various sizes of metal oil drums, improving the applicability of the high-sealing metal oil drum opening structure. Furthermore, according to the above operation, before the two sets of cutting blades 16 open the lid, the first control panel de-energizes multiple sets of electromagnets 21, allowing the movement of multiple sets of iron counterweights 10. When multiple sets of arc-shaped brake pads 28 contact the high-sealing metal oil drum... After the outer wall is closed, multiple sets of second electric telescopic rods 24 are shortened using multiple sets of second control panels. During this process, four sets of lifting plates 25 gradually move into the interior of four sets of grooves 23. When multiple sets of brake blocks 27 contact the ground, friction ensures the stability of the highly sealed metal oil drum, allowing for opening. After opening, multiple sets of second electric telescopic rods 24 are extended using multiple sets of second control panels. When four sets of second universal wheels 26 on the same side support a set of counterweights 10 on the same side, multiple sets of counterweights 10 can be attached to multiple sets of electromagnets 21. Then, the first control panel is used to energize the multiple sets of electromagnets 21, completing the connection of the multiple sets of iron counterweights 10. Through the counterweights 10, the opening operation can be achieved without moving the metal oil drum.This improves the usability of the opening structure for high-sealing metal oil drums.
