Description
Technical Field
[0001] This utility model relates to the field of power engineering technology, specifically to a cable installation adjustment frame for power engineering construction. Background Technology
[0002] In power engineering construction, especially in the indoor cable laying process, the installation of cable trays is a crucial step. The traditional cable tray hoisting method generally adopts an adjustment frame structure consisting of two threaded rods and an angle plate at their lower ends. The upper ends of the two threaded rods are fixed to the building roof or top plate by expansion nuts and other components, while the lower ends are locked to a horizontal angle plate by nuts. This angle plate is mainly used to fix and support the cable trays during cable installation.
[0003] However, this traditional adjustment frame has significant drawbacks in practical applications. The primary problem is that the installation is inefficient and the adjustment is cumbersome: installers need to adjust the nuts on the two screws separately to accurately control the level of the corner plate and the installation elevation of the cable tray. This is not only time-consuming and laborious, but also requires repeated measurement and adjustment. At the same time, the level accuracy of the corner plate cannot be guaranteed. Secondly, because the entire weight of the cable tray and cables is transferred to the roof through a single connection point at the upper end of two screws, stress concentration is prominent. When the weight of the cables carried by the cable tray is too great, or when subjected to external vibrations or accidental contact during maintenance, the huge concentrated load can easily cause the roof fixing points to loosen, creating a safety hazard. At the same time, if the cable tray and trough are accidentally bumped or vibrated, the pressure will be concentrated in the middle and upper sections of the threaded screws, which may lead to bending deformation or even breakage of the screws. Utility Model Content
[0004] In order to solve the technical problems existing in the prior art, the present invention provides a cable installation adjustment frame for power engineering construction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable installation adjustment frame for power engineering construction, comprising two fully threaded screws and an angle plate sleeved between the lower ends of the two fully threaded screws. The lower part of the angle plate is fixed by a nut threaded to the surface of the fully threaded screws. It also includes an auxiliary component, which includes a synchronization rod disposed on the surface of the angle plate and on the same axis as the fully threaded screws. The upper end of the synchronization rod is fixed with a synchronization plate that is horizontally inserted between the two fully threaded screws and is used to ensure the bending strength of the fully threaded screws. The surface of the synchronization rod is also provided with a retainer for always ensuring that the angle plate is in a horizontal state and for pre-positioning the angle plate by engaging with the inner wall of the fully threaded screw.
[0006] Preferably, the threaded screw is hollow, and the auxiliary components also include through holes on the side of the threaded screw. The synchronizing rods are located between the four through holes. When the two synchronizing rods are inserted into the two threaded screws together, the synchronizing plate contacts the through holes to guide the movement path of the lower corner plate.
[0007] Preferably, the width of the synchronizing plate is greater than the distance between the two threaded screws, and the thickness of the synchronizing plate is equal to the diameter of the perforation.
[0008] Preferably, the auxiliary component further includes an insertion hole on the surface of the angle plate and the shape of which is consistent with the lower end face of the all-thread screw, the insertion hole for the angle plate to be fitted onto the surface of the all-thread screw.
[0009] Preferably, the two sides of the casing are designed with raised edges, and the casing is made of flexible stainless steel.
[0010] Preferably, the auxiliary component also includes a locking tooth disposed on the inner wall of the full-thread screw. The locking tooth is adapted to the locking housing. When the synchronizing rod is inserted into the full-thread screw, the locking housing will follow the synchronizing rod into the full-thread screw and engage with the locking tooth to pre-position the diagonal plate.
[0011] Compared with the prior art, this utility model provides a cable installation adjustment frame for power engineering construction, which has the following advantages: During cable tray installation, the timing rod, which is coaxial with the threaded rod, helps the angle plate to be horizontal and stably and vertically fitted onto the surfaces of the two threaded rods. When the timing rod is inserted into the threaded rod, the retaining clip on the surface of the timing rod can be used to achieve the effect of pre-positioning the angle plate in a standard posture after it is fitted onto the surfaces of the two threaded rods.
[0012] When the synchronizing rod is inserted into the inside of the threaded screw, the synchronizing plate at the upper end of the synchronizing rod will be inserted horizontally into the through holes of the two threaded screws, so that the pressure after one side is subjected to force can be evenly distributed through the synchronizing plate, improving the strength of the main stress range of the threaded screw and enhancing the stability of the cable tray.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0016] like Figure 1-6 As shown, this embodiment proposes a cable installation adjustment frame for power engineering construction to improve the horizontal stability of cable tray installation. It includes two fully threaded screw rods 1 and an angle plate 2 sleeved between the lower ends of the two fully threaded screw rods 1. The angle plate 2 is used to install the cable tray. The lower part of the angle plate 2 is fixed by a nut 3 threaded to the surface of the fully threaded screw rod 1. It also includes an auxiliary component 4, which includes a synchronization rod 403 set on the surface of the angle plate 2 and on the same axis as the fully threaded screw rod 1. The upper end of the synchronization rod 403 is fixed with a synchronization plate 404 that is horizontally inserted between the two fully threaded screw rods 1 and is used to ensure the bending strength of the fully threaded screw rod 1. The surface of the synchronization rod 403 is also provided with a retainer 405 to always keep the angle plate 2 in a horizontal state and to engage with the inner wall of the fully threaded screw rod 1 to pre-position the angle plate 2. In power engineering construction, especially in the indoor cable laying process, the installation of cable trays is a crucial step. Generally, cable trays are supported and fixed by being suspended from the roof cable trays. When installing the cable tray, first use expansion bolts to fix the upper end of the threaded rod 1 to the roof. After the two threaded rods 1 are fixed, the angle plate 2 can be placed on the surface of the two threaded rods 1. Finally, the nut 3 is put on the lower end of the threaded rod 1 to limit the height of the angle plate 2. The all-thread screw 1 is hollow. The auxiliary component 4 also includes a through hole 401 on the side of the all-thread screw 1. The synchronizing rod 403 is located between the four through holes 401. When two synchronizing rods 403 are inserted into two all-thread screws 1 together, the synchronizing plate 404 contacts the through holes 401 to guide the movement path of the lower corner plate 2. The width of the synchronizing plate 404 is greater than the distance between the two all-thread screws 1, and the thickness of the synchronizing plate 404 is equal to the diameter of the through holes 401. When the angle plate 2 is fitted onto the surface of the two fully threaded screws 1, the synchronizing rod 403 above the angle plate 2 is first pre-inserted into the two fully threaded screws 1. The synchronizing rod 403 and the fully threaded screws 1 are on the same axis, so the angle plate 2 can be adjusted in attitude after it is fitted onto the surface of the two fully threaded screws 1, so that the angle plate 2 is in a horizontal state. Meanwhile, a synchronization plate 404 is provided between the upper ends of the two synchronization rods 403. When the synchronization plate 404 follows the synchronization rod 403 into the interior of the two threaded screws 1, it is in a horizontal state and its surface is in contact with the through hole 401 of the threaded screw 1. After the corner plate 2 is installed, the horizontally inserted synchronization plate 404 can cooperate with the two threaded screws 1 to form a stable frame to resist external pressure. At the same time, it can also effectively avoid the problem of pressure concentration on the upper section of the threaded screw 1 due to external pressure or the movement of the slot, causing the connection point between the threaded screw 1 and the roof to loosen and the section of the threaded screw 1 to be severely stressed. The auxiliary component 4 also includes a socket 406 formed on the surface of the angle plate 2 and with the same shape as the lower end face of the all-thread screw 1. The socket 406 allows the angle plate 2 to be fitted onto the surface of the all-thread screw 1. When the angle plate 2 is fitted onto the surface of the two threaded screws 1, the lower end of the threaded screw 1 will first enter the insertion hole 406 of the angle plate 2. The shape of the insertion hole 406 is consistent with the shape of the lower end face of the threaded screw 1. Therefore, by using the insertion hole 406 in conjunction with the threaded screw 1, the angle plate 2 can be adjusted so that the angle plate 2 is installed in a horizontal position. The 405 caliper has a raised edge design on both sides and is made of flexible stainless steel. The auxiliary component 4 also includes a locking tooth 402 disposed on the inner wall of the full-thread screw 1. The locking tooth 402 is adapted to the locking housing 405. When the synchronizing rod 403 is inserted into the full-thread screw 1, the locking housing 405 will follow the synchronizing rod 403 into the full-thread screw 1 and engage with the locking tooth 402 to pre-position the diagonal plate 2. When the angle plate 2 is installed with the assistance of the synchronizing rod 403, the retaining shell 405 will follow the synchronizing rod 403 into the interior of the threaded screw 1. Since the two sides of the retaining shell 405 are designed with raised edges, and the lower part of the retaining tooth 402 is set at an angle, the retaining shell 405 will continuously squeeze against the inclined surface of the retaining tooth 402 and repeatedly perform contraction / expansion movements as it moves upward. When the angle plate 2 is fitted onto the two four-piece surfaces and reaches the specified height, since the raised edge range of the retaining shell 405 is greater than or equal to the upper area of the retaining tooth 402, the personnel can stop the rise of the angle plate 2, so that the angle plate 2 can be pre-positioned in a horizontal position. Finally, the personnel pinch and gather the lower end of the threaded screw 1, and put the nut 3 on the lower end of the threaded screw 1 and turn it upward until the upper end of the nut 3 is in contact with the lower part of the corner plate 2, thus completing the overall installation of the cable tray. In actual operation, firstly, the upper end of the threaded rod 1 is fixed to the roof using expansion bolts. After the two threaded rods 1 are fixed, the angle plate 2 can be placed on the surface of the two threaded rods 1. Finally, the nut 3 is fitted onto the lower end of the threaded rod 1 to limit the height of the angle plate 2. When the angle plate 2 is fitted onto the surface of the threaded rod 1, the synchronous rod 403, which is on the same axis as the threaded rod 1, can help the angle plate 2 to be in a horizontal state and stably and vertically fitted onto the surface of the two threaded rods 1. When the step rod 403 is inserted into the full-thread screw 1, the synchronization plate 404 at the upper end of the synchronization rod 403 will be inserted laterally into the through holes 401 of the two full-thread screws 1, so that the pressure after one side is subjected to force can be evenly distributed through the synchronization plate 404, improving the strength of the main force range of the full-thread screw 1, enhancing the stability of the cable tray, and using the retainer 405 on the surface of the synchronization rod 403, after the corner plate 2 is sleeved on the surface of the two full-thread screws 1, the corner plate 2 can be pre-positioned in a standard posture.
