Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to an auxiliary installation device for installing a lifting sling. Background Art

[0002] To facilitate the installation and maintenance of large equipment in nuclear power plants, the ceilings are often equipped with lifting points (such as hooks or rings). Maintenance personnel must thread lifting slings through these points during lifting operations. Because the ceilings are often very high, maintenance personnel must erect scaffolding and then ascend using the scaffolding to thread the slings through the points. To ensure safety, maintenance personnel must also wear safety belts.

[0003] It can be seen from this that the seemingly simple operation of "threading the lifting sling into the lifting point" often consumes a lot of time of maintenance personnel, thereby extending the maintenance period. Summary of the Invention

[0004] Based on this, it is necessary to provide an auxiliary installation device for installing a lifting sling, which is intended to reduce the time consumed by maintenance personnel to thread the lifting sling into the lifting point, so as to shorten the maintenance period.

[0043] like Figures 1 to 3 As shown, an embodiment of the present application provides an auxiliary installation device 10 for installing a lifting sling. The auxiliary installation device 10 includes a long rod assembly 100, a mounting frame 200, a first rolling member 300, a second rolling member 400, a first drive assembly 500, and a second drive assembly 600. Specifically, the mounting frame 200 is disposed at one end of the long rod assembly 100, and the first rolling member 300 and the second rolling member 400 are disposed parallel to each other. There is a gap between the first rolling member 300 and the second rolling member 400 for the lifting sling to pass through. The first rolling member 300 is mounted on the mounting frame 200 via the first drive assembly 500, and the second rolling member 400 is mounted on the mounting frame 200 via the second drive assembly 600. The first drive assembly 500 and the second drive assembly 600 are configured to drive the first rolling member 300 and the second rolling member 400 to rotate at the same speed in opposite directions.

[0044] It can be understood that the first rolling element 300 and the second rolling element 400 are arranged parallel to each other, which means that the axis of the first rolling element 300 and the axis of the second rolling element 400 are arranged parallel to each other.

[0045] The auxiliary installation device 10 for installing a lifting belt in an embodiment of the present application can be used to insert the lifting belt into a lifting point (such as a hook or ring) set on the factory ceiling. During operation, the maintenance personnel can first insert one end of the lifting belt into the gap between the first rolling element 300 and the second rolling element 400, and use the first rolling element 300 and the second rolling element 400 to clamp the end of the lifting belt. Then, the long rod assembly 100 of the auxiliary installation device 10 is held and lifted to deliver the end of the lifting belt to the location of the lifting point on the factory ceiling. The first drive assembly 500 and the second drive assembly 600 are then activated. Under the drive action of the first drive assembly 500 and the second drive assembly 600, the first rolling element 300 and the second rolling element 400 rotate in opposite directions and at the same speed to transport the lifting belt in the direction of the lifting belt, thereby inserting the lifting belt into the lifting point. The auxiliary installation device 10 for installing a lifting sling in the embodiment of the present application allows maintenance personnel to insert the lifting sling into the lifting point without setting up scaffolding or climbing to a height. This simple operation helps reduce the time taken for the operation, thereby shortening the maintenance period. In addition, it can also avoid maintenance personnel having to climb to a height, thereby improving the safety of the operation process.

[0046] In some embodiments, the auxiliary installation device 10 further includes a guide slot 700 disposed on the mounting frame 200. The guide slot 700 is disposed on one side of the first rolling element 300 and the second rolling element 400, and is positioned near the gap. This arrangement allows the ends of the lifting belt to move in a desired direction while the first and second rolling elements 300 and 400 are conveying the lifting belt, thereby preventing the ends of the lifting belt from sagging due to gravity. This significantly improves the success rate of the lifting belt ends entering the lifting point. It is understood that maintenance personnel can adjust the position of the mounting frame 200 so that the guide slot 700 contacts the lifting point. In this way, once the lifting belt is freed from the guide slot 700 during conveyance, it can be inserted into the lifting point.

[0047] In some embodiments, the extending direction of the guide groove 700, the axial direction of the first rolling element 300, and the extending direction of the long pole assembly 100 are perpendicular to each other. This arrangement makes the relative position relationship between the conveying direction of the lifting belt and the long pole assembly 100 clear, allowing maintenance personnel to more easily control the movement direction of the lifting belt when using the auxiliary installation device 10.

[0048] It can be understood that the extension direction of the guide groove 700, the axial direction of the first rolling element 300, and the extension direction of the long rod assembly 100 are perpendicular to each other. Specifically, the axial direction of the first rolling element 300 is perpendicular to the extension direction of the long rod assembly 100, the extension direction of the guide groove 700 is perpendicular to the extension direction of the long rod assembly 100, and the extension direction of the guide groove 700 is also perpendicular to the axial direction of the first rolling element 300.

[0049] In some embodiments, as Figures 2 to 5 As shown, the mounting frame 200 includes a fixed bracket 220 and an adjustable bracket 210 connected to the fixed bracket 220, and the long rod assembly 100 is connected to the fixed bracket 220. The adjustable bracket 210 includes a first frame body 211, a second frame body 212 and a locking buckle 213, wherein the first frame body 211 is connected to the fixed bracket 220, the first drive assembly 500 is disposed on the first frame body 211, and a sleeve 2111 is formed on the first frame body 211. The second drive assembly 600 is disposed on the second frame body 212, and a plug-in portion 2121 is provided on the second frame body 212. The plug-in portion 2121 cooperates with the sleeve 2111, and the locking buckle 213 is sleeved on the sleeve 2111 for locking the sleeve 2111 with the plug-in portion 2121.

[0050] In this embodiment, the first drive assembly 500 is disposed on the first frame 211 of the adjustable bracket 210, and the second drive assembly 600 is disposed on the second frame 212 of the adjustable bracket 210. The first frame 211 is formed with a sleeve 2111, and the second frame 212 is provided with an inserting portion 2121 that can be inserted into the sleeve 2111. The inserting portion 2121 and the sleeve 2111 can be locked by a locking buckle 213, thereby making the distance between the first drive assembly 500 and the second drive assembly 600 adjustable. The specific adjustment process is: first, open the locking buckle 213, then adjust the depth of the inserting portion 2121 inserted into the sleeve 2111, and then lock the locking buckle 213 after the adjustment is completed. By adjusting the distance between the first drive assembly 500 and the second drive assembly 600, the size of the gap between the first rolling element 300 and the second rolling element 400 can be adjusted so that the gap can be adapted to lifting slings of different specifications, thereby making the auxiliary installation device 10 suitable for the installation process of lifting slings of various specifications.

[0051] Of course, in other embodiments, a plug-in portion is provided on the first frame 211, and a sleeve is provided on the second frame 212. The first frame 211 and the second frame 212 cooperate with each other through the plug-in portion and the sleeve to achieve the first frame 211 and the second frame 212 being closer to or farther away from each other, thereby adjusting the distance between the first drive assembly 500 and the second drive assembly 600.

[0052] In some embodiments, as Figure 2 、 Figure 4 As shown, the side wall of the sleeve 2111 is provided with a sliding groove 2112, the extension direction of the sliding groove 2112 being parallel to the axial direction of the sleeve 2111, and the plug-in portion 2121 is provided with a protrusion structure 2122 adapted to the sliding groove 2112. The engagement between the protrusion structure 2122 and the sliding groove 2112 restricts the rotation of the plug-in portion 2121 relative to the sleeve 2111, thereby facilitating the first rolling element 300 and the second rolling element 400 to always remain parallel to each other.

[0053] In some embodiments, as Figure 4 、 Figure 5 As shown, the first drive component 500 is connected to the first frame 211 through the elastic component 800; the elastic component 800 includes a guide column 810, a linear bearing 820 and a spring 830, both ends of the guide column 810 are connected to the first frame 211, the linear bearing 820 is connected to the first drive component 500, the linear bearing 820 is sleeved on the guide column 810, and the spring 830 is sleeved on the guide column 810 and one end is against the linear bearing 820.

[0054] Because the thickness of the lifting belt changes after long-term use, the thickness of different parts of the lifting belt will be uneven. During the process of the lifting belt being transported by the first rolling element 300 and the second rolling element 400, the thicker part of the lifting belt may get stuck when it moves to the gap between the first rolling element 300 and the second rolling element 400. To avoid the above problem, in this embodiment, an elastic component 800 is provided between the first drive component 500 and the first frame 211. The linear bearing 820 in the elastic component 800 can move up and down along the guide column 810. Moreover, under the action of the spring 830, the first drive component 500 always maintains a movement tendency toward the second drive component 600. Therefore, during the transportation of the lifting belt, as the thickness of the lifting belt changes, the distance between the first drive component 500 and the second drive component 600 can be adaptively changed, thereby avoiding the problem of the lifting belt getting stuck due to the uneven thickness.

[0055] Furthermore, the linear bearing 820 is provided with an anti-rotation limit structure 821 for preventing the linear bearing 820 from rotating, thereby maintaining the first rolling element 300 in a parallel relationship with the second rolling element 400. In one example, the anti-rotation limit structure 821 is a limit block provided on the linear bearing 820, which abuts against the first frame 211, thereby preventing the linear bearing 820 from rotating relative to the first frame 211. In another example, the anti-rotation limit structure 821 is a limit groove provided on the inner surface of the linear bearing 820. Correspondingly, the outer surface of the guide post 810 is provided with a protrusion that matches the limit groove, thereby preventing the linear bearing 820 from rotating relative to the guide post 810.

[0056] In some embodiments, the auxiliary installation device 10 further includes a guide wheel 900, which is positioned near the first end of the first rolling element 300 and covers the gap. The first end of the first rolling element 300 is the end of the first rolling element 300 facing away from the adjustable bracket 210. The guide wheel 900 has two functions. First, the guide wheel 900 forms a barrier at the first end of the first rolling element 300, thereby preventing the lifting belt from slipping out of the first end of the first rolling element 300. Second, if the lifting belt deviates during transportation and contacts the guide wheel 900, the guide wheel 900 can allow the lifting belt to continue moving in the direction of transportation.

[0057] In some embodiments, as Figure 5 As shown, the first drive assembly 500 includes a first motor bracket 510 and a first motor 520 mounted on the first motor bracket 510. The first motor 520 is connected to the first rolling element 300. The second drive assembly 600 includes a second motor bracket 610 and a second motor 620 mounted on the second motor bracket 610. The second motor 620 is connected to the second rolling element 400. In this embodiment, the first motor 520 is mounted on the first motor bracket 510, which provides a mounting position for the first motor 520. The first motor 520 is connected to the first rolling element 300 and is used to provide power to rotate the first rolling element 300. Similarly, the second motor 620 is mounted on the second motor bracket 610, which provides a mounting position for the second motor 620. The second motor 620 is connected to the second rolling element 400 and is used to provide power to rotate the second rolling element 400.

[0058] In some embodiments, the first rolling element 300 is a first roller, and the first drive assembly 500 is disposed inside the first rolling element 300. The second rolling element 400 is a second roller, and the second drive assembly 600 is disposed inside the second rolling element 400. In this embodiment, the first rolling element 300 is a first roller and the first drive assembly 500 is disposed inside the first rolling element 300, and the second rolling element 400 is a second roller and the second drive assembly 600 is disposed inside the second rolling element 400. This configuration makes the auxiliary installation device 10 compact and can reduce the overall volume of the auxiliary installation device 10.

[0059] In some embodiments, as Figure 6As shown, both the first and second rolling elements 300 and 400 include a rigid support body 1501 and a flexible layer 1502 covering the rigid support body 1501. Friction grooves 1503 are provided on the surface of the flexible layer 1502. In this embodiment, the rigid support body 1501 in the first and second rolling elements 300 and 400 serves to enhance the structural strength and rigidity of the first and second rolling elements 300 and 400, making them less susceptible to damage and deformation. Furthermore, the first and second rolling elements 300 and 400 are further provided with a flexible layer 1502 covering the rigid support body 1501. During transport of the lifting belt, the flexible layer 1502 maintains close contact with the lifting belt, thereby preventing wear and tear. Furthermore, the friction grooves 1503 on the surface of the flexible layer 1502 increase friction between the flexible layer 1502 and the lifting belt, thereby preventing slippage during transport.

[0060] In some embodiments, the long rod assembly 100 includes a telescopic rod 110 and a lock 120 provided on the telescopic rod 110, and the mounting frame 200 is provided at one end of the telescopic rod 110. By adjusting the length of the telescopic rod 110, the auxiliary installation device 10 can cover different height ranges. In actual applications, the telescopic rod 110 can be adjusted to a suitable length according to the height of the lifting point. After the telescopic rod 110 is adjusted to a suitable length, the telescopic rod 110 can maintain the length unchanged through the locking action of the lock 120. It can be understood that the telescopic rod 110 can be any existing telescopic rod 110 that can be telescoped, and the lock 120 can be any existing lock 120 that can lock the telescopic rod 110. This application will not elaborate on this.

[0061] In some embodiments, the long pole assembly 100 further includes an anti-slip handle 130, which is disposed at an end of the telescopic pole 110 away from the mounting bracket 200. Maintenance personnel can hold the anti-slip handle 130 when using the auxiliary installation device 10, so that it is less likely to slip when held.

[0062] In some embodiments, a remote control switch 1000 is provided at the end of the telescopic rod 110 away from the mounting bracket 200. The remote control switch 1000 is wirelessly connected to the first drive assembly 500 and the second drive assembly 600. This arrangement avoids the problem of wired connections that make it difficult to retract and extend the cable when the length of the telescopic rod 110 changes.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
