[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.

[0016] Example 1 like Figures 1 to 5 As shown in this embodiment, a cable tray for use on offshore platforms includes: The outer U-shaped cable tray seat 1 has a rectangular through hole 101 on its bottom inner wall, and an inner U-shaped cable tray seat 2 is provided on its inner side. Limiting sliding holes 201 are provided on the front and rear inner walls of the inner U-shaped cable tray seat 2. The anti-wear lateral guide slide assembly consists of two sets, which are respectively fixedly connected to the inner front wall and the inner rear wall of the outer U-shaped cable tray seat 1, and are respectively located in the corresponding limiting slide holes 201; the anti-wear lateral guide slide assembly is used to guide the inner U-shaped cable tray seat 2 in the lateral direction of anti-wear through the corresponding limiting slide holes 201. A rectangular guide rod 302 is fixedly connected between the inner walls of both sides of the rectangular perforation 101, and a hard anti-slip rubber pad 303 is embedded and fixed on the front side of its bottom. A rectangular sliding sleeve 3 is fixedly connected to the bottom left side of the inner U-shaped cable tray seat 2. Two first anti-wear balls 301 are movably embedded on its top inner wall, bottom inner wall, front inner wall and rear inner wall. A rectangular guide rod 302 is located between eight first anti-wear balls 301 and is in movable contact with the first anti-wear balls 301. The spring-loaded clamping assembly is embedded and fixed at the bottom of the rectangular sliding sleeve 3 and is pressed tightly against the bottom of the hard anti-slip rubber pad 303. A U-shaped handle 404 is fixedly connected to its bottom end. The spring-loaded clamping assembly is used to lock the rectangular sliding sleeve 3 in conjunction with the hard anti-slip rubber pad 303, and is used to easily unlock and drive the rectangular sliding sleeve 3 to move laterally when the U-shaped handle 404 is pulled down and moved laterally. The lateral movement of the rectangular sliding sleeve 3 drives the inner U-shaped cable tray seat 2 to move laterally. The lateral movement of the inner U-shaped cable tray seat 2 is used to remove it to adjust the total length formed by it and the outer U-shaped cable tray seat 1. The fixing plate 5 is connected to the front side of the outer U-shaped cable tray seat 1, and a clamp 501 is fixedly connected to the bottom of its front side; the clamp 501 is used for personnel to temporarily fix it to the fixed bracket of the offshore platform by bolts. In this embodiment, the two first anti-wear balls 301 at the bottom are located behind the hard anti-slip pad 303; wherein the bottom of the rectangular guide rod 302 is provided with an insert groove for bonding and fixing to the outside of the hard anti-slip pad 303.

[0017] Furthermore, the fixing plate 5 is welded to the front side of the outer U-shaped cable tray seat 1.

[0018] Furthermore, such as Figure 1 , 3 As shown in Figure 5, the anti-wear transverse guide slide assembly includes a limiting slider 202. The opposing sides of the two limiting sliders 202 are fixedly connected to the front inner wall and the rear inner wall of the outer U-shaped cable tray seat 1, respectively. The limiting sliders 202 are located in the corresponding limiting slide holes 201. Two second anti-wear balls 203 are movably embedded in the top and bottom of the limiting sliders 202. The top inner wall and the bottom inner wall of the limiting slide holes 201 are in active contact with the corresponding two second anti-wear balls 203, respectively. In this embodiment, by means of the cooperation between the limiting slider 202 and the second anti-wear ball 203, when the inner U-shaped cable tray seat 2 moves laterally, the two limiting sliding holes 201 are driven to slide laterally in the corresponding four second anti-wear balls 203 respectively. By utilizing the method that the multiple second anti-wear balls 203 can rotate due to friction, the anti-wear guiding effect is achieved during the lateral movement.

[0019] Furthermore, such as Figure 3 and 4 As shown, the spring-loaded compression assembly includes a rectangular sleeve 4, a rectangular pressure block 401, two vertical guide rods 402, and two compression springs 403 in a compressed state. The top of the rectangular sleeve 4 is set as an opening and is embedded and fixed to the bottom of the rectangular sliding sleeve 3. The rectangular pressure block 401 is slidably sleeved in the rectangular sleeve 4. The top of the rectangular pressure block 401 is set as a sawtooth anti-slip structure and is pressed tightly against the bottom of the hard anti-slip rubber pad 303. The two vertical guide rods 402 are fixedly connected to the bottom of the rectangular pressure block 401. The bottom ends of the two vertical guide rods 402 slide out to the bottom of the rectangular sleeve 4 and are fixedly connected to the top of the U-shaped handle 404. The two compression springs 403 are fixedly connected between the bottom of the rectangular pressure block 401 and the inner wall of the bottom of the rectangular sleeve 4. The two compression springs 403 are respectively movably sleeved on the corresponding vertical guide rods 402. In this embodiment, the bottom of the rectangular sliding sleeve 3 is provided with an insert hole that is fixedly connected to the outside of the rectangular sleeve 4; the bottom inner wall of the rectangular sleeve 4 is provided with two vertical guide holes that are respectively slidably fitted onto the outside of the corresponding vertical guide rod 402, so as to guide the vertical sliding of the vertical guide rod 402. In this implementation scheme, the rectangular sleeve 4, rectangular pressure block 401, vertical guide rod 402, and compression spring 403 work together. The elastic force of the two compressed springs 403 elastically tightens the rectangular pressure block 401 upwards, causing its top serrated anti-slip structure to press tightly against the bottom of the hard anti-slip pad 303. The friction between these two components locks the rectangular sleeve 3 in place, thus unlocking the inner U-shaped cable tray seat 2. When adjusting horizontally, the operator first pulls down the loop handle 404, causing it to move the rectangular pressure block 401 downwards through the two vertical guide rods 402, separating it from the hard anti-slip pad 303. This further compresses the two compression springs 403, releasing the lock. Then, the loop handle 404 is moved horizontally, causing the rectangular sleeve 4 to move horizontally through the two vertical guide rods 402. The rectangular sleeve 4 then moves the rectangular sleeve 3 horizontally, causing the eight first anti-wear balls 301 to roll outside the rectangular guide rod 302. The horizontal movement of the rectangular sleeve 3 moves the inner U-shaped cable tray seat 2. The inner U-shaped cable tray seat 2 moves laterally to adjust its total length with the outer U-shaped cable tray seat 1, allowing for convenient and flexible adjustment of the cable tray length. After adjustment, the downward pull on the U-shaped handle 404 is released. The elastic force of the two compression springs 403, which are in a compressed state, drives the rectangular pressure block 401 to move upward, causing the serrated anti-slip structure at its top to press against the bottom of the hard anti-slip pad 303, thus locking it in place. This allows for convenient and quick unlocking and adjustment of the total length of the outer U-shaped cable tray seat 1 and the inner U-shaped cable tray seat 2, improving the flexibility of use. The adjustable total length reduces the amount of cable tray used, and the telescopic adjustable design allows for easy retraction of the inner U-shaped cable tray seat 2 back into the outer U-shaped cable tray seat 1, reducing the occupied length, facilitating transportation, and improving overall flexibility.

[0020] It should be noted that the rectangular guide rod 302, rectangular sliding sleeve 3, limit slider 202, rectangular sleeve 4, rectangular pressure block 401, vertical guide rod 402, outer U-shaped cable tray seat 1 and inner U-shaped cable tray seat 2 are preferably made of stainless steel. The stainless steel material has the advantages of high hardness, high wear resistance and good maintenance-free effect, which ensures the stability and life of long-term cyclic temporary application. It should be further explained that the clamp 501 consists of two semi-circular clamps, two fixing bolts, two nuts, and two anti-slip rubber pads. The above components are all conventional components of the existing clamp 501. During installation, the clamp 501 is clamped onto the offshore platform mounting bracket by passing the fixing bolts through the bolt holes at the corresponding positions of the two semi-circular clamps and then tightening them with the nuts. This installation and fixing method is a well-known and mature technology in the industry and will not be described in detail here.

[0021] This embodiment allows for convenient and quick unlocking and horizontal adjustment of the total length of the outer U-shaped cable tray seat 1 and the inner U-shaped cable tray seat 2, thereby achieving convenient, quick, and flexible adjustment of the cable tray length, improving usability. By adjusting the total length, the amount of cable tray used is reduced, and by utilizing the telescopic adjustable method, it is convenient to retract the inner U-shaped cable tray seat 2 into the outer U-shaped cable tray seat 1, thereby reducing the occupied length, facilitating transportation, and improving usability and convenience.

[0022] The usage method of this embodiment is as follows: When using the cable tray applied to the offshore platform, the clamp 501 is used for personnel to temporarily clamp and fix it to the fixed support of the offshore platform with bolts to support the external U-shaped cable tray seat 1. When the total length needs to be adjusted, the personnel first pull down the loop handle 404, which causes the rectangular pressure block 401 to move downward through the two vertical guide rods 402 and separate from the hard anti-slip rubber pad 303, and continue to compress the two compression springs 403 to release the locking state. Then, the loop handle 404 is moved horizontally. 4. The rectangular sleeve 4 moves laterally via two vertical guide rods 402. The rectangular sleeve 4 moves laterally via the rectangular sliding sleeve 3. The rectangular sliding sleeve 3 causes eight first anti-wear balls 301 to roll outside the rectangular guide rods 302. The lateral movement of the rectangular sliding sleeve 3 causes the inner U-shaped cable tray seat 2 to move laterally. When the inner U-shaped cable tray seat 2 moves laterally, it causes two limiting sliding holes 201 to slide laterally on the corresponding four second anti-wear balls 203. By utilizing the friction of multiple second anti-wear balls 203, they can rotate, thus achieving the effect of anti-wear and lateral guidance during lateral movement. The inner U-shaped cable tray seat 2 is moved laterally to adjust its total length with the outer U-shaped cable tray seat 1, achieving convenient and flexible adjustment of the cable tray length. After adjustment, the downward pull on the U-shaped handle 404 is released. At this time, the elastic force of the two compression springs 403 in the compressed state drives the rectangular pressure block 401 to move upward, so that the serrated anti-slip structure at its top is pressed against the bottom of the hard anti-slip pad 303. The friction between the two is used to lock the rectangular sliding sleeve 3, and then the cable tray is moved again. The inner U-shaped cable tray seat 2 is locked in place, allowing for convenient and quick unlocking and horizontal adjustment of the total length of the outer U-shaped cable tray seat 1 and the inner U-shaped cable tray seat 2. This enables convenient, quick, and flexible adjustment of the cable tray length, improving usability. The adjustable total length reduces the amount of cable tray used, and the telescopic adjustable design allows the inner U-shaped cable tray seat 2 to be easily retracted into the outer U-shaped cable tray seat 1, reducing the occupied length, facilitating transportation, and improving usability and convenience.

[0023] Example 2 like Figure 6As shown, this embodiment differs from Embodiment 1 in that: the fixing plate 5 is detachably connected to the front side of the outer U-shaped cable tray seat 1; the fixing plate 5 is in movable contact with the front side of the outer U-shaped cable tray seat 1; the front side of the outer U-shaped cable tray seat 1 has three threaded grooves in a triangular shape; the threaded grooves are threaded with hexagonal socket bolts 502; the front side of the fixing plate 5 has three bolt holes that are in movable contact with the outer side of the corresponding hexagonal socket bolts 502; the inner wall of the front side of the hexagonal socket bolts 502 is in tight contact with the front side of the fixing plate 5.

[0024] This embodiment allows for the disassembly and assembly of the fixing plate 5, enabling personnel to flexibly replace fixing plates 5 of different lengths according to usage needs, thereby further improving the flexibility of use.

[0025] The method of use in this embodiment is as follows: The difference from the first embodiment is that it also has the following functions: By using the set threaded groove, the internal hex bolt 502 and the bolt through hole, the fixing plate 5 is threadedly fixed. Afterwards, the personnel can operate the internal hex bolt 502 with a hex wrench to rotate it in the opposite direction, so as to separate it from the corresponding threaded groove, release the locking of the fixing plate 5, and then the fixing plate 5 can be disassembled. By using the detachable method of the fixing plate 5, the personnel can flexibly replace the fixing plate 5 of different lengths according to the usage needs, further improving the flexibility of use.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
