[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0031] The special tool for lifting machine seal boxes provided in this embodiment of the invention uses a clamping structure to hold the machine seal box during movement and a fixing structure to secure it, thus preventing the machine seal box from slipping while being moved. Therefore, the special tool for lifting machine seal boxes provided in this embodiment of the invention avoids the safety hazard of multiple people wearing protective gloves and lifting the machine seal box during disassembly and assembly operations, which poses a risk of injury from slipping machine seal boxes.
[0032] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the special tool and system for hoisting mechanical seal boxes provided in the embodiments of this utility model.
[0033] Figure 1 This is a structural schematic diagram of a special tool for lifting mechanical seal boxes, provided in an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating an application scenario of a special tool for lifting mechanically sealed boxes, provided as an embodiment of this utility model. (See diagram below.) Figure 1 and Figure 2 As shown, the special tool for lifting mechanical sealing boxes includes: a clamping structure 10, a perforated structure 12, a lifting ring structure 13, and a fixing structure 14; the perforated structure 12 is fixed to the top of the clamping structure 10, and the lifting ring structure 13 is located above the clamping structure 10 through the perforated structure 12; the clamping structure includes a U-shaped frame 11 and a support plate 15; the U-shaped frame 11 includes a first clamping arm 111, a second clamping arm 112, and a third clamping arm 113 integrally formed, with a clamping opening 16 formed between the first clamping arm 111 and the third clamping arm 113; the perforated structure 12 is fixedly installed on the first clamping arm 111;
[0034] The support plate 15 is fixed on the side of the third clamping arm 113 facing the clamping opening 16 at the position corresponding to the clamping opening 16, and the fixing structure 14 is set on the first clamping arm 111 corresponding to the clamping opening 16; the clamping structure 10 is used to clamp the machine seal box 18, and the fixing structure 14 is used to fix the machine seal box 18.
[0035] Specifically, using the special hoisting tool for machine seal boxes provided in this embodiment of the invention, when moving the machine seal box 18, the clamping structure 10 clamps the machine seal box 18, and the fixing structure 14 fixes the machine seal box 18 (e.g., ...). Figure 2 As shown in the figure, this allows the mechanical seal box 18 to be moved, avoiding the safety hazard of the mechanical seal box 18 slipping and injuring personnel that is often caused by the method of carrying and disassembling the machine while wearing anti-smashing gloves in related technologies.
[0036] The special tool for lifting mechanical seal boxes provided in this embodiment of the utility model includes: a clamping structure 10, a perforated structure 12, a lifting ring structure 13, and a fixing structure 14; the perforated structure 12 is fixed to the top of the clamping structure 10, and the lifting ring structure 13 is located above the clamping structure 10 through the perforated structure 12; the clamping structure 10 includes a U-shaped frame 11 and a support piece 15; the U-shaped frame 11 includes a first clamping arm 111, a second clamping arm 112, and a third clamping arm 113 integrally formed, with a clamping opening 16 formed between the first clamping arm 111 and the third clamping arm 113; the perforated structure 12 is fixedly disposed on the first clamping arm 111; the support piece 15 is fixed on the side of the third clamping arm 113 facing the clamping opening 16, corresponding to the position of the clamping opening 16, and the fixing structure 14 is disposed on the first clamping arm 111 corresponding to the clamping opening 16; the clamping structure 10 is used to clamp the mechanical seal box 18, and the fixing structure 14 is used to fix the mechanical seal box 18. The special tool for lifting machine seal boxes 18 provided in this embodiment of the utility model uses a clamping structure 10 to hold the machine seal box 18 during movement, and a fixing structure 14 to fix the machine seal box 18. This prevents the machine seal box 18 from slipping while being moved. Therefore, the special tool for lifting machine seal boxes provided in this embodiment of the utility model avoids the safety hazard of the machine seal box 18 slipping and injuring personnel, which is a common practice in related technologies where multiple people wearing protective gloves are used for lifting and disassembly operations.
[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the support piece 15 is arc-shaped, with the curvature of the arc facing the third clamping arm 113. Specifically, since the mechanical seal box 18 is usually circular, when the clamping structure 10 clamps the mechanical seal box 18, the arc-shaped support piece 15 can match the inner wall of the shaft in the mechanical seal box 18, which is beneficial for supporting the mechanical seal box 18 during the moving process.
[0038] In some embodiments, the support piece 15 may be configured in other shapes to match the mechanical seal box 18 of other shapes to be clamped by the clamping structure 10, and this embodiment of the present invention is not limited in this respect.
[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing structure 14 includes a nut 141 and a bolt 142 that matches the nut 141; the nut 141 is fixedly connected to the first clamping arm 111, and the screw-in and screw-out directions of the bolt 142 correspond to the location of the clamping opening 16.
[0040] Specifically, to prevent the mechanical seal box 18 from falling off, a fixing structure 14 is welded onto the first clamping arm 111. The fixing structure 14 can be an 8.8 grade nut 141 or a high-strength bolt 142, thereby fixing the mechanical seal box 18.
[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamping structure 10, the perforated structure 12, and the lifting ring structure 13 are all made of metal, which is carbon steel or alloy steel.
[0042] Carbon steel and alloy steel have the advantages of high strength and durability, as well as high temperature resistance and corrosion resistance. Setting the clamping structure 10, the perforation structure 12 and the lifting ring structure 13 as carbon steel or alloy steel is beneficial to extending the service life of the special tool for lifting mechanical seal boxes.
[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the surfaces of the clamping structure 10, the perforated structure 12, and the lifting ring structure 13 are provided with an anti-rust coating, which includes a zinc plating layer and / or a paint layer.
[0044] Specifically, by applying an anti-rust coating to the surfaces of the clamping structure 10, the perforated structure 12, and the lifting ring structure 13, it is beneficial to extend the service life of the special tool for lifting mechanical seal boxes and reduce maintenance costs. For example, the anti-rust coating can form a dense barrier, isolating the surface of the special tool for lifting mechanical seal boxes from direct contact with corrosive substances such as water, oxygen, and salt, thereby extending the service life of the special tool for lifting mechanical seal boxes.
[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the outer corners between the first clamping arm 111 and the second clamping arm 112 are set as rounded corner structures 17, and the outer corners between the second clamping arm 112 and the third clamping arm 113 are also set as rounded corner structures 17.
[0046] Specifically, the rounded corner structure 17 improves the stability of the clamping structure 10. Simultaneously, the rounded corner structure 17 reduces burrs or sharp edges, enhancing safety and preventing operator injury. Furthermore, the rounded corner structure 17 makes the clamping structure 10 appear smoother and more aesthetically pleasing.
[0047] For example, the preparation process of the special tool for sealing the hoisting machine provided in this embodiment of the utility model can be as follows: First, prepare the materials for making the hoisting machine sealing box, using more than 10 steel plates cut into different shapes, as well as 8.8 grade bolts, steel bars, and flat iron to prepare the materials for making the special tool for sealing the hoisting machine sealing box; Second, use curved iron plates and shapes cut by gas cutting to make the frame of the hoisting machine sealing box; Third, to prevent the sealing box from falling off, weld 8.8 grade nuts on the top of the steel plates and use high-strength bolts for fixing; Fourth, to facilitate the hoisting of the sealing box, weld lifting rings on the special tool for easy use with hand chain hoists or electric hoists for hoisting.
[0048] Figure 3This is a schematic diagram of a special lifting system for mechanically sealed boxes provided by this utility model, as shown in the embodiments of this utility model. Figures 1 to 3 The special system for hoisting mechanical seal boxes includes the special tools for hoisting mechanical seal boxes as described in the above embodiments, and therefore has the same or similar beneficial effects, which will not be elaborated here.
[0049] Specifically, the special system for hoisting mechanical seal boxes includes a lifting device, which uses a lifting ring structure to lift the special hoisting tool for the mechanical seal box 18.
[0050] In some embodiments, such as Figure 3 As shown, the lifting device includes a hoist 21, a rope 20, and a drive component 22; the drive component 22 is connected to the hoist 21 via the rope 20, and the hook 19 of the hoist 21 is used to lift the lifting ring structure 13.
[0051] Specifically, the hook 19 of the hoist 21 can lift the lifting ring structure 13, and in conjunction with the drive component 22, it can move the mechanical seal box 18.
[0052] Therefore, to facilitate routine maintenance and replacement of mechanical seals, this utility model embodiment uses steel plates and bolts to create a special tool for lifting mechanical seal boxes. A frame for lifting the mechanical seal box is made using a curved iron plate and a shape cut with an oxy-acetylene torch. To prevent the mechanical seal box from falling off, nuts are welded to the top of the steel plate and bolts are used for fixation. Lifting rings are welded to the special tool for easy lifting with a hand-operated hoist. Using this special tool, the mechanical seal box can be easily and smoothly removed from the pump shaft. This standardizes routine maintenance operations, effectively avoids the safety hazards of multiple people lifting the mechanical seal box (such as crushing or squeezing injuries), and improves the inherent safety of maintenance operations.
