Multiple sets of mounting holes are formed on each baffle, with two holes in each set parallel to the mounting plate. Clamping components are provided on each baffle corresponding to one set of mounting holes. Each clamping component includes a fixing post corresponding to one set of mounting holes. Connecting plates are provided on both fixing posts, and a fixing plate is connected to the two connecting plates. A circular through hole is provided at the center of the fixing plate, and a rotating rod is installed within the circular through hole. A pulley is connected to the rotating rod. The fixing posts are connected by screws passing through the mounting holes. Therefore, this utility model provides a cable pulley bracket that can fix the pulley using mounting holes and two sets of clamping components, thereby allowing for height adjustment when supporting cables, making operation more convenient.
[0004] This patent allows the pulley to be fixed by mounting holes and two sets of clamping components, which can adjust its height when supporting the cable, making the operation more convenient. However, the existing pulley does not have the function of monitoring cable pressure, and cannot detect real-time monitoring and deformation risk control problems during cable laying in a timely manner. The safety and reliability of cable laying need to be improved. Summary of the Invention
[0005] The purpose of this invention is to address the limitations of existing structures, which can only protect a single group of pins at a time. This single-group protection method is inconvenient during chip installation or removal, increasing operation time and potentially reducing the precision of the fit between the pins and the protective sleeve due to repeated operations, thus affecting the stability and reliability of the chip. Furthermore, it fails to provide comprehensive protection for all pins at once.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a smart pulley for cable tray installation, comprising a cable tray body, wherein a convenient replacement component is connected to the surface of the cable tray body, the convenient replacement component includes a support frame, the support frame has a slot, a bidirectional screw is inserted into the support frame near the slot, one end of the bidirectional screw is connected to a throttle, two sets of moving blocks are symmetrically connected to the surface of the bidirectional screw, the top of each set of moving blocks is connected to a limit plate, and a pressure sensor is provided between the two sets of limit plates.

[0013] Furthermore, one end of the push rod is connected to a handle, the other end of the push rod is connected to a push plate, the surface of the push plate is connected to an insert block, and the surface of the insert block is provided with a bevel.
[0014] Furthermore, the position and size of the insert block match the position and size of the slot, and the insert block and the slot form an interlocking connection. The two side surfaces of the photoelectric length sensor are in contact with the two sets of fixing blocks.
[0015] Furthermore, the push plate and the spring form an elastic structure.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the pressure sensor at the bottom of the pulley body can be used to test the pressure.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, as Figure 1 - Figure 4 As shown, this utility model provides an intelligent pulley for cable tray installation, including a cable tray body 1. A convenient replacement component 2 is connected to the surface of the cable tray body 1. The convenient replacement component 2 includes a support frame 201. The support frame 201 has a slot 202 inside. A bidirectional screw 203 is inserted into the support frame 201 near the slot 202. One end of the bidirectional screw 203 is connected to a handle 204. Two sets of moving blocks 205 are symmetrically connected to the surface of the bidirectional screw 203. The top of each set of moving blocks 205 is connected to a limit plate 206. A pressure sensor 207 is provided between the two sets of limit plates 206. The bidirectional screw 203 and the handle 204 are fixedly connected. The bidirectional screw 203 and the moving blocks 205 are threadedly connected. The inner wall of the limit plate 206 is provided with an anti-slip pad. The limit plate 206 is arc-shaped. The size of the limit plate 206 matches the size of the pressure sensor 207.
[0023] The overall effect of Embodiment 1 is that, during use, the pulley body 4 is fixed to the surface of the pressure sensor 207 by the limiting block 5, and the pressure sensor 207 achieves the purpose of pressure detection. When the pressure sensor 207 needs to be disassembled and replaced after long-term use, the handle 204 can be rotated in the reverse direction to drive the bidirectional screw 203 to reverse. When the bidirectional screw 203 reverses, it will also rotate in the opposite direction with the two sets of moving blocks 205 at the same time. In turn, the two sets of limiting plates 206 will move to both sides through the reverse rotation of the screw, thereby releasing the limiting fixation of the pressure sensor 207. Then the pressure sensor 207 can be removed and a new pressure sensor 207 can be installed. 07 is placed in the slot 202. At this time, the handle 204 can be rotated forward, so that the two sets of moving blocks 205 can drive the limit plate 206 to move inward, thereby clamping and fixing the pressure sensor 207. Then, the pulley body 4 is placed on the surface of the pressure sensor 207. Both sides of the pulley body 4 are fitted with bearing sleeves to reduce wear on the pressure sensor 207. Then, the limit block 5 is fixed to the upper ends of both sides of the pulley body 4. In this way, the cable pressure can be monitored in real time, effectively preventing deformation and damage, and ensuring the stable and safe power transmission. At the same time, through the design of the connecting iron plate 6, the angle between each pulley body 4 can be adjusted individually from 0° to 90°, which is suitable for various laying scenarios. When the surface pressure of the pressure sensor 207 is too high and exceeds the set safety threshold, the alarm 7 will automatically sound to remind the construction personnel, effectively reducing the probability of cable damage.
[0024] Example 2, as Figure 5 and Figure 6 As shown, a set of support frames 201 is connected to a convenient installation component 3 at the top. The convenient installation component 3 includes a fixing frame 301. Fixing blocks 302 are connected to the top of both sides of the fixing frame 301. A photoelectric length sensor 303 is arranged between the two sets of fixing blocks 302. Slots 304 are opened on both sides of the photoelectric length sensor 303. Springs 305 are connected inside the two sets of fixing blocks 302. A push rod 306 is inserted into the spring 305. A handle 307 is connected to one end of the push rod 306. A push plate 308 is connected to the other end of the push rod 306. An insert block 309 is connected to the surface of the push plate 308. The surface of the insert block 309 is provided with a bevel. The position and size of the insert block 309 match the position and size of the slot 304. The insert block 309 and the slot 304 form an insert connection. The two sides of the photoelectric length sensor 303 are in contact with the two sets of fixing blocks 302. An elastic structure is formed between the push plate 308 and the spring 305.
[0025] The effect achieved by the entire embodiment 2 is that when installing the photoelectric length sensor 303, it can be pushed between the two sets of fixing blocks 302. When the angled positions of the two sets of insert blocks 309 are squeezed by the photoelectric length sensor 303, they will automatically retract into the fixing blocks 302. When the photoelectric length sensor 303 is completely pushed into the surface of the fixing frame 301, the spring 305 will push the push plate 308 through its own elastic force, which will drive the insert block 309 to be inserted into the slot 304 for fixing. This completes the installation of the photoelectric length sensor 303. After the photoelectric length sensor 303 is turned on, it will perform displacement measurement by emitting and receiving light signals. When an object moves in the optical path, it reflects or blocks the light signal, thereby achieving high-precision measurement. It is usually used to monitor rapid dynamic changes and can be used in cable length measurement scenarios. The length is measured by monitoring the reflection or blocking of the light signal during the movement of the cable. When the photoelectric length sensor 303 is not needed for measurement, the handles 307 can be pulled to both sides at the same time, so that the handles 307 can drive the push plate 308 to squeeze the spring 305 through the push rod 306, and the insert block 309 can be pulled out from the slot 304. At this time, the photoelectric length sensor 303 can be removed directly.
[0026] Working principle: The pressure sensor 207 at the bottom of the pulley body 4 can be used to test the pressure. When the pressure sensor 207 is damaged, the handle 204 can be turned to drive the bidirectional screw 203 to rotate. The screw rotation will cause the two sets of limit plates 206 to move away from the pressure sensor 207. Then the pressure sensor 207 can be removed and replaced. In this way, the cable pressure can be monitored in real time, effectively preventing deformation and damage, and ensuring the stability and safety of power transmission. The cable length can be measured by activating the photoelectric length sensor 303. After data calibration, the laying length can be measured, which is convenient for the construction manager to count materials and construction progress, and facilitates project management.
[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
