Technical Field

[0001] This utility model relates to the technical field of lifting rod devices for hoisting, and in particular to a lifting rod device for cable tray hoisting. Background Technology

[0002] Cable tray hoisting devices are commonly used in the field of building electrical systems. They are suitable for cable tray installation in office buildings, factories, shopping malls, and other scenarios. Their core function is to stably suspend the cable tray from the ceiling, floor, or steel structure, enabling neat cable laying. They can support the weight of the cable tray and cables, ensuring the accuracy of the cable tray installation. They also facilitate later inspection and maintenance and can be flexibly adjusted according to the height of the space to meet the wiring needs of different scenarios. They are a key supporting component of electrical wiring systems.

[0003] In practical work, the existing cable tray hoisting lifting device, using lifting rods and expansion bolts in combination, can meet the basic requirements for stabilizing cable trays, but the following problems still exist: Common cable tray hoisting devices are usually installed and fixed with expansion bolts. When the installation environment is in a humid environment such as a basement or garage, moisture can seep into the connection gaps, causing electrochemical corrosion, which eventually leads to the weakening of bolt strength and affects the overall service life. Therefore, this application provides a cable tray hoisting device to meet the requirements. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figure 1 - Figure 6 As shown, this embodiment provides a technical solution: a lifting rod device for cable tray hoisting, including a lifting rod body 1 and an expansion bolt 11 disposed on the top of the lifting rod body 1, and further including: Limiting component 2 includes a fixing ring 21 disposed on the side of the lifting rod body 1, a first support plate 22 connected to the top of the fixing ring 21, a second support plate 23 connected to the side of the first support plate 22, and a touch ring 25 disposed at the bottom of the second support plate 23. The protective component 3 includes a protective plate 31 disposed on the side of the first support plate 22, a spring piece 24 connected to the bottom of the second support plate 23, the bottom of the spring piece 24 being fixedly connected to the top of the contact ring 25, a groove 26 being formed on the outer surface of the first support plate 22, a slide rod 27 being slidably connected to the inner cavity of the groove 26, and a snap-fit ​​groove 28 being formed on the outer surface of the first support plate 22. By setting a fixing ring 21, the first support plate 22 can be supported. After connecting the suspension rod body 1 to the expansion screw 11, the protective plate 31 is pushed counterclockwise upwards by hand, which causes the slide rod 27 to move along the inner cavity of the groove 26. When the slide rod 27 moves to a certain position, the top of the slide rod 27 contacts the bottom of the contact ring 25, which causes the spring piece 24 to be compressed. At this time, the slide rod 27 continues to move. When the sliding rod 27 moves into the inner cavity of the slide groove 26, the spring piece 24 releases stress, thereby causing the contact ring 25 to reset. This ensures that the sliding rod 27 is engaged with the inner cavity of the slide groove 26, thus fixing the position of the protective plate 31 and ensuring that the protective plate 31 can provide protection for the connection between the lifting rod body 1 and the expansion bolt 11. When it is necessary to perform safety maintenance on the connection between the lifting rod body 1 and the expansion bolt 11, the protective plate 31 is first pushed upward, which causes the sliding rod 27 to push the contact ring 25 upward, thereby disengaging the sliding rod 27 from the inner cavity of the slide groove 26. Continuing to rotate the protective plate 31 clockwise causes the sliding rod 27 to move to the top of the fixing ring 21, which in turn causes the protective plate 31 to move downward, releasing the protection provided to the connection between the lifting rod body 1 and the expansion bolt 11.

[0017] Furthermore, such as Figure 3 and Figure 5As shown: The inner wall of the protective plate 31 is provided with a protective coating 32. The protective coating 32 is specifically an epoxy coal tar coating. The coating is composed of epoxy resin and coal tar. After curing, the two will form a dense cross-linked structure, which can completely isolate water vapor penetration and has extremely strong adhesion to the metal substrate, thus preventing the coating from peeling off. Through the cooperation of the protective plate 31 and the protective coating 32, the connection between the suspension rod body 1 and the expansion bolt 11 can be protected against moisture, effectively extending the overall service life. Example

[0018] like Figure 1-6 As shown: In use: First, connect the bottom of the lifting rod body 1 to the expansion bolt 11. Then, manually push the protective plate 31 upwards counterclockwise, which will cause the sliding rod 27 to move along the inner cavity of the slide groove 26. When the sliding rod 27 moves to a certain position, the top of the sliding rod 27 contacts the bottom of the contact ring 25, which will cause the spring 24 to be compressed. At this time, the sliding rod 27 continues to move and enters the inner cavity of the slide groove 26. When the sliding rod 27 and the slide groove 26 are engaged, the spring 24 releases stress, which will cause the contact ring 25 to reset. This allows for auxiliary fixation of the position of the slide rod 27. Similarly, when safety maintenance is required at the connection between the suspension rod body 1 and the expansion bolt 11, the protective plate 31 is first pushed upwards, which causes the slide rod 27 to push the contact ring 25 upwards, thereby achieving the effect of the slide rod 27 disengaging from the inner cavity of the slide groove 26. Continuing to rotate the protective plate 31 clockwise causes the slide rod 27 to move to the top of the fixing ring 21, which in turn causes the protective plate 31 to move downwards, releasing the protection provided to the connection between the suspension rod body 1 and the expansion bolt 11.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
