Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a cable laying device for electrical automation equipment in HVAC engineering. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, such as overhead, underground (ducts and direct burial), underwater, wall, and tunnel laying. For example, urban trunk cables (relay and user trunk cables) are generally laid in ducts to ensure communication security and reliability, convenient installation and replacement, and aesthetic appeal. Therefore, the appropriate selection of cable laying method is crucial for ensuring the transmission quality, reliability, and construction and maintenance of the line.

[0003] However, when cables are in use, their operating temperature changes with the load. These temperature changes cause the cables to expand and contract, increasing the pressure between multiple cables. Over time, this can damage the cable sheath, affecting the cable's daily operation and making it inconvenient to use. Utility Model Content

[0004] To solve the above-mentioned technical problems, a cable laying device for electrical automation equipment in HVAC engineering is provided. This technical solution solves the problem mentioned in the background technology that when cables are used, the operating temperature of the cables changes with the load. The temperature change will cause the cables to expand and contract, which will increase the pressure between multiple cables. Over time, this will cause damage to the cable sheath, thus affecting the daily operation of the cables and making them inconvenient to use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable laying device for electrical automation equipment in HVAC engineering includes a laying frame. The top of the laying frame is provided with a cable placement groove. An adjustment mechanism is provided inside the laying frame. The adjustment mechanism includes a first slide rod. Several sets of the first slide rods are provided. The several sets of the first slide rods are all set in the mounting groove opened at the top of the laying frame. Two sets of movable blocks are slidably installed on the outer surface of the several sets of the first slide rods. The top of the several sets of movable blocks is provided with a movable plate.

[0007] Preferably, both sets of movable plates have movable grooves on their outer sides, both sets of movable grooves have guide rollers rotatably installed inside them, and both sets of movable plates have springs on their inner sides.

[0008] Preferably, the top of the laying frame is provided with a top cover, and two sets of insert frames are provided on the left and right sides of the top cover.

[0009] Preferably, guide strips are provided on the left and right sides of the laying frame corresponding to the positions of the two sets of insert frames, and the two sets of guide strips are slidably installed inside the insert frames.

[0010] Preferably, a connecting frame is provided on the front side of the laying frame, and three sets of connecting frames are provided. A pin is provided on the rear side of the laying frame corresponding to the positions of the three sets of connecting frames.

[0011] Preferably, the inner sides of the laying frame are provided with fixed plates corresponding to the positions of the three sets of movable plates, and the inner sides of the three sets of fixed plates are provided with second slide rods. The front and rear ends of the three sets of movable plates are respectively slidably installed on the outer surface of the second slide rods.

[0012] Preferably, the left and right side walls of the laying frame are provided with the same movable groove as the surface of the movable plate, and the two sets of movable grooves are movably mounted with the same guide rollers.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up an adjustment mechanism, a movable block and a movable plate slidably mounted on the first slide rod, together with a spring on the inner side of the movable plate, can buffer the compressive force caused by the cable's volume change when the cable expands and contracts due to temperature changes. This allows the movable plate to move flexibly according to the cable's expansion and contraction, effectively alleviating the pressure caused by thermal expansion and contraction between multiple cables, preventing damage to the cable sheath due to excessive pressure, and ensuring the normal use of the cable. Secondly, several sets of guide rollers are also set up. By rotating and installing guide rollers on the outer side of the movable plate and in the movable grooves on the left and right side walls of the laying frame, the guide rollers can reduce the friction between the cable and the device when the cable moves within the laying device, thereby reducing cable wear, further protecting the cable, extending its service life, and making the cable more convenient to use.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1 As shown, a cable laying device for electrical automation equipment in HVAC engineering includes a laying frame 1, a top cover 3 at the top of the laying frame 1, two sets of insertion frames 301 on the left and right sides of the top cover 3, and guide strips 101 on the left and right sides of the laying frame 1 corresponding to the positions of the two sets of insertion frames 301. Both sets of guide strips 101 are slidably installed inside the insertion frames 301.

[0025] In this solution, the guide bar 101 is slidably installed inside the insert frame 301, which realizes convenient opening and closing and stable connection between the top cover 3 and the laying frame 1, and facilitates the maintenance of the adjustment mechanism 4.

[0026] Reference Figure 1-2 As shown, a connecting frame 102 is provided on the front side of the laying frame 1, and three sets of connecting frames 102 are provided. A pin 103 is provided on the rear side of the laying frame 1 at the position corresponding to the three sets of connecting frames 102.

[0027] In this solution, the quick splicing and fixing of multiple laying frames 1 is achieved through the cooperation of the pin 103 and the connecting frame 102. The length of the device can be flexibly adjusted according to actual needs to meet the cable laying requirements in different scenarios.

[0028] Reference Figure 1-3As shown, the inner top of the laying frame 1 is provided with a cable placement groove 2. The laying frame 1 is provided with an adjustment mechanism 4. The adjustment mechanism 4 includes a first slide rod 401. Several sets of first slide rods 401 are provided. The several sets of first slide rods 401 are all set in the mounting groove 104 opened at the inner top of the laying frame 1. Two sets of movable blocks 402 are slidably installed on the outer surface of the several sets of first slide rods 401. Movable plates 403 are provided at the top of the several sets of movable blocks 402. Movable grooves 404 are opened on the outer side of the two sets of movable plates 403. Guide rollers 405 are rotatably installed inside the two sets of movable grooves 404. Springs 406 are provided on the inner side of the two sets of movable plates 403. Fixed plates 407 are provided on the front and rear inner sides of the laying frame 1 corresponding to the positions of the three sets of movable plates 403. Second slide rods 408 are provided on the inner side of the three sets of fixed plates 407. The front and rear ends of the three sets of movable plates 403 are respectively slidably installed on the outer surface of the second slide rods 408.

[0029] In this design, the sliding of the movable block 402 on the first slide bar 401 enables the flexible horizontal movement of the movable plate 403. Furthermore, the second slide bar 408 further limits and guides the movable plate 403, ensuring its stability during movement and improving the overall reliability of the device. Secondly, the guide rollers 405 facilitate smooth cable sliding during installation, reducing friction between the cable and the device, preventing cable surface wear, and extending cable lifespan. Simultaneously, the elasticity of the spring 406 provides a buffer when the cable experiences thermal expansion and contraction, allowing for adaptive adjustment based on cable thickness.

[0030] Reference Figure 2 As shown, the left and right side walls of the laying frame 1 are provided with the same movable grooves 404 as those on the surface of the movable plate 403, and the two sets of movable grooves 404 are movably mounted with the same guide rollers 405.

[0031] In this solution, by also installing guide rollers 405 on the side wall of the laying frame 1, the cable can be laid smoothly in all directions inside the device, and the cable can be further protected no matter which direction it enters or exits from the device.

[0032] The working principle of this utility model is as follows: During use, the top cover 3 and the laying frame 1 are slidably installed inside the insertion frame 301 via the guide strip 101, achieving convenient opening and closing and a stable connection, facilitating maintenance of the adjustment mechanism 4. Secondly, when multiple laying frames 1 cooperate with the connecting frame 102 via the pin 103, rapid splicing and fixing can be achieved, and the length of the device can be flexibly adjusted according to actual needs. Furthermore, when the adjustment mechanism 4 is working, the movable block 402 slides on the first slide rod 401, driving the movable plate 403 to move flexibly in the horizontal direction. The movable plate 403 slides on the outer surface of the second slide rod 408 at its front and rear ends, further ensuring the stability of movement. The guide roller 405 rotates in the movable groove 404 on the outer side of the movable plate 403 and the movable groove 404 on the side wall of the laying frame 1, so that the cable can slide smoothly during the laying process, reduce friction, and avoid wear on the cable surface. The spring 406 is inside the movable plate 403. When the cable expands and contracts due to heat, the spring 406 generates an elastic effect, so that the movable plate 403 generates a certain buffer, which can be adaptively adjusted according to the thickness of the cable.
