Description

Technical Field

[0001] This application relates to the field of coal mine equipment technology, and in particular to a four-corner tank guide shaping device. Background Technology

[0002] In mine hoisting systems, the auxiliary shaft, as a crucial link between the underground and surface areas, undertakes the vertical transportation of personnel, materials, and equipment. The four-corner cage guides, a key component of the auxiliary shaft hoisting system, guide the cage to move smoothly and accurately along predetermined tracks, ensuring the safety and efficiency of the hoisting process. However, in actual operation, due to potential unexpected impacts from the cage or oversized materials entering or exiting the cage, the four-corner cage guides may occasionally deform. This deformation not only affects the normal operation of the cage but may also threaten the overall safety of the hoisting system.

[0003] Currently, the main repair method for deformed corner tank passages is physical hammering. Specifically, technicians use tools such as sledgehammers to directly strike the deformed areas, causing plastic deformation of the passage material through external force, thus restoring its original shape. While this method is simple to operate and requires no complex equipment or technical support, it has several limitations in practical application. It relies heavily on the operator's experience and force control, making it difficult to guarantee the precision and consistency of the repair results.

[0004] While using a sledgehammer to reshape the hoisting system can address corner deformation to some extent, this method is time-consuming, labor-intensive, and inefficient, failing to meet the mine's need for rapid system recovery. Secondly, the hammering process may cause deformation in other parts of the hoisting system, leading to unsatisfactory repair results and potentially exacerbating the damage. More seriously, sledgehammering damages the mechanical properties of the metal material, reducing its strength and toughness, thereby increasing the risk of hoisting system breakage and shortening its service life.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0036] For example, in operational scenarios involving the installation and maintenance of corner guideways in mines, industrial shafts, and other similar locations, the integrity and stability of the corner guideways, as critical guiding and supporting structures, are essential for the safe operation of the equipment. However, due to long-term exposure to heavy loads, complex stresses, and potential accidental collisions, the corner guideways 5 undergoing reshaping inevitably experience localized deformation. This deformation not only affects the normal operating trajectory of the equipment and increases operating resistance but may also lead to serious safety hazards. Therefore, timely and effective reshaping and repair of the deformed areas is crucial.

[0037] Current methods for repairing deformed corner tank passageways often rely on manual hammering. This method is not only labor-intensive but also lacks guaranteed repair results. Manual hammering involves significant uncertainty in controlling the force and direction, easily causing new deformations in other previously intact parts of the passageway due to repeated hammering. Consequently, the repair is not only ineffective and fails to achieve the intended correction, but may even further exacerbate the damage to the passageway, significantly shortening its lifespan and increasing equipment maintenance costs and safety risks.

[0038] Because some technologies use a sledgehammer to reshape the corner guideways, the repair results are unsatisfactory and may even worsen the damage. To solve this problem, this application provides a corner guideway reshaping device. The structure of each part of the corner guideway reshaping device is described below:

[0039] like Figure 1 The diagram shown is a structural schematic of the four-corner tank channel shaping device in this application.

[0040] This application provides a four-corner can guide shaping device, comprising:

[0041] A first steel plate 1, with a jack 2 connected to one side of the first steel plate 1; the jack 2 is welded to one side of the first steel plate 1.

[0042] The second steel plate 3 is connected to the first steel plate 1 via a fixing mechanism 4 and is parallel to the first steel plate 1. The jack 2 is located between the second steel plate 3 and the first steel plate 1. A four-corner canal passage 5 to be shaped is provided between the second steel plate 3 and the jack 2. The second steel plate 3 and the first steel plate 1 are both 40mm thick. The first steel plate 1 is fixed by the fixing mechanism 4, and the second steel plate 3 is slidably connected to the fixing mechanism 4. By adjusting the distance between the second steel plate 3 and the first steel plate 1, the four-corner canal passage 5 to be shaped is fixed between the second steel plate 3 and the jack 2.

[0043] The jack 2 is configured to reshape the deformed parts of the four corner cannula 5 to be reshaped. By aligning the deformed parts of the four corner cannula 5 to be reshaped with the power unit 22 of the jack 2, the jack 2 is activated, thereby reshaping the deformed parts of the four corner cannula 5 through the power unit 22. This saves manpower and prevents deformation of other parts of the cannula due to repeated hammering, which could lead to unsatisfactory repair results or even aggravate the damage to the cannula, thus increasing the service life of the four corner cannula.

[0044] This application provides a four-corner can guideway shaping device, which precisely aligns the deformed parts of the four-corner can guideway 5 to be shaped with the power unit 22 of the jack 2. The jack 2, as a mature hydraulic or mechanical power device, has a power unit 22 with powerful pushing or stretching capabilities. After ensuring accurate positioning, the jack 2 is activated, and the power unit 22 begins to apply force according to a preset force and direction. Under the powerful force of the power unit 22, the deformed parts of the four-corner can guideway 5 gradually deform, restoring to their original standard shape. Using this method, the entire shaping process eliminates the need for extensive manual hammering, significantly saving labor costs. Simultaneously, because the jack 2 can precisely control the magnitude and direction of the force, it effectively avoids deformation of other parts of the can guideway caused by improper human operation. This allows the repaired four-corner can guideway 5 to better restore its original geometry and mechanical properties, ensuring the stability and safety of equipment operation, thereby increasing the service life of the four-corner can guideway, reducing downtime for maintenance due to frequent can guideway damage, and improving production efficiency.

[0045] In this embodiment, the jack 2 includes:

[0046] The main body 21 is connected to the first steel plate 1 on one side and a power unit 22 is provided on the other side of the main body 21. The power unit 22 is configured to shape the deformed parts of the four corner tank passages 5 to be shaped. The operating handle 23 is provided on the main body 21 and connected to the power unit 22.

[0047] Specifically, when the operating handle 23 is rotated in the first direction, the power unit 22 moves closer to the location of the second steel plate 3; when the operating handle 23 is rotated in the second direction, the power unit 22 moves away from the location of the second steel plate 3; the second direction is opposite to the first direction. The first direction is clockwise, and the second direction is counterclockwise. When the operating handle 23 is rotated in the first direction, the power unit 22 moves closer to the location of the second steel plate 3, thereby shaping the deformed parts of the four corner guideways 5 to be shaped; when the operating handle 23 is rotated in the second direction, the power unit 22 moves away from the location of the second steel plate 3, restoring its original position.

[0048] In this embodiment, the handle of the operating handle 23 is provided with a rubber sleeve. Since the operating handle 23 is typically made of hard materials such as metal, its surface is relatively smooth and its texture is hard. When the user rotates the operating handle 23, especially when a large force is required to operate the jack, a large frictional force and relative sliding tendency will occur between the hand and the operating handle 23. The user's hand is easily injured during the friction with the operating handle 23, such as skin abrasion. To effectively prevent hand injury when rotating the operating handle 23, this application specifically provides a rubber sleeve on the handle of the operating handle 23. The rubber sleeve has good elasticity and softness; it can fit tightly against the surface of the handle of the operating handle 23, increasing the friction between the hand and the operating handle 23, allowing the user to grip the operating handle 23 more stably and reducing the risk of hand slippage. At the same time, the soft texture of the rubber sleeve can act as a cushion, dispersing the pressure on the hand when the user applies force, reducing the hard contact between the hand and the operating handle 23, thereby preventing hand injury due to excessive friction and pressure.

[0049] In this embodiment, openings are provided opposite to each other along the length direction of the first steel plate 1 and the second steel plate 3, and the openings are respectively provided on both sides of the first steel plate 1 and the second steel plate 3; wherein, the fixing mechanism 4 passes through the openings to connect the first steel plate 1 to the second steel plate 3.

[0050] In this embodiment, the fixing mechanism 4 includes a double-ended bolt 41, which passes through the opening to connect the first steel plate 1 to the second steel plate 3; the double-ended bolt 41 is long. 20; Nut 42, which is screwed onto the double-ended bolt 41 to fix the four corner tank passage 5 to be shaped between the second steel plate 3 and the jack 2.

[0051] In this embodiment, the diameter of the opening is larger than the diameter of the double-ended bolt 41. By setting the diameter of the opening to be larger than the diameter of the double-ended bolt 41, the second steel plate 3 can be slidably connected to the double-ended bolt 41, thereby fixing the four-corner can channel 5 to be shaped between the second steel plate 3 and the first steel plate 1.

[0052] In this embodiment, the two ends of the double-ended bolt 41 are provided with sliding portions 411, and a snap-fit ​​portion 412 is provided between the sliding portions 411; the diameter of the sliding portion 411 is smaller than the diameter of the opening; the diameter of the snap-fit ​​portion 412 is larger than the diameter of the opening; wherein, the projection of the snap-fit ​​portion 412 toward the jack 2 completely covers the jack 2.

[0053] For example, by providing the sliding part 411, since the diameter of the sliding part 411 is smaller than the diameter of the opening, the second steel plate 3 can be slidably connected to the double-ended bolt 41. By providing the snap-fit ​​part 412, since the diameter of the snap-fit ​​part 412 is larger than the diameter of the opening, the second steel plate 3 cannot pass through the snap-fit ​​part 412. Since the projection of the snap-fit ​​part 412 onto the jack 2 completely covers the jack 2, the second steel plate 3 is prevented from contacting the power unit 22, thereby avoiding damage to the power unit 22 due to frequent impacts from the second steel plate 3 and improving the service life of the jack 2.

[0054] like Figure 2 The diagram shown is a structural schematic of the pre-tightening device in this application.

[0055] In this embodiment, the device further includes:

[0056] A pre-tightening device 6 is configured to screw the nut 42 onto the stud bolt 41. The pre-tightening device 6 includes: a pre-tightening portion 61, the inner shape of which is the same as the outer shape of the nut 42; and a handle 62 connected to the pre-tightening portion 61. The pre-tightening device 6 is adapted to the nut 42 and can fit tightly against it, allowing the user to screw the nut 42 onto the stud bolt 41 using the handle 62.

[0057] In this embodiment, the inner side of the preload portion 61 is provided with threads. The main function of the preload portion 61 is to screw the nut 42 onto the stud bolt 41. By providing threads on the inner side of the preload portion 61, the accuracy and stability of the screwing are ensured. During the screwing process of the nut 42, even under the action of external forces such as vibration and impact, the nut 42 is not easy to loosen, ensuring that the nut 42 is stably and quickly screwed onto the stud bolt 41.

[0058] This application provides a four-corner tank track shaping device, including a jack 2, the bottom of which is welded to a 40mm thick first steel plate 1. Holes are made at the four corners of the first steel plate 1, and long... 20 double-ended bolts are fixed with nuts 42. After the double-ended bolts 41 pass through the four corner guides 5 to be shaped, the other end is also made of a 40mm thick second steel plate 3. Holes are drilled at the four corners of the second steel plate 3, and the bolts are installed on the other end of the double-ended bolts 41 and pass through nuts 42. In order to fix them on the four corner guides 5 to be shaped, the four corner nuts 42 can be tightened with a pre-tightening device 6. The four corner guides 5 to be shaped are pre-tightened with jack 2 and the second steel plate 3. Then, the deformed parts of the four corner guides 5 to be shaped are shaped with the operating handle 23 of jack 2. This reduces the labor intensity of users and improves the shaping efficiency. At the same time, the four corner guide shaping device can reduce the wear and fatigue of the four corner guides, reduce the number of shaping times, and improve the safety and stability of the four corner guide operation. It effectively solves the problem that the current shaping method of using a sledgehammer to strike the four corner guides for deformation problems leads to unsatisfactory repair results and may even aggravate the damage of the four corner guides.
