Description

Technical Field

[0001] This utility model relates to the technical field of cable winding and unwinding devices, specifically a mobile winding and unwinding device for long-distance flexible temperature measuring cables. Background Technology

[0002] Long-distance flexible temperature measuring cables are widely used in industrial testing, geological exploration, environmental monitoring and other fields. They can transmit temperature signals over long distances to achieve remote temperature measurement.

[0003] Patent CN220334431U discloses a mobile cable winding and unwinding device, relating to the field of cable winding and unwinding technology. It includes a base, a drive motor, a cable reel, and a cable reel shaft. The drive motor is located on the base in front of the cable reel. Brackets are fixedly mounted on both sides of the base. The brackets are arc-shaped, with the center of the arc-shaped bracket being the axis of the drive motor's output shaft. The output shaft of the drive motor is connected to the cable reel shaft via a transmission chain. This patent not only solves the problem of the entire cable winding and unwinding device being too wide due to the drive motor being mounted outside the mounting base, but also optimizes the adjustment process by eliminating the need to adjust the transmission chain between the drive motor and the cable reel shaft when adjusting the height of the mounting base, as the length of the transmission chain remains constant at the same radius.

[0004] As shown in the above technology, the temperature measuring head at the end of the existing long-distance temperature measuring cable is easily damaged during the winding and unwinding process. Due to its precision and susceptibility to impact, it lacks effective protective measures and may be squeezed or collided during handling or winding, resulting in a decrease in measurement accuracy or direct failure.

[0014] Preferably, a bottom frame is fixedly connected to the surface of the tray, an elastic block is fixedly connected to one side of the bottom frame surface, and a locking post is fixedly connected to one side of the elastic block via a movable plate.

[0015] This utility model provides a mobile retraction and deployment device for long-distance flexible temperature measuring cables. Compared with the prior art, it has the following advantages:

[0016] 1. This long-distance flexible temperature measuring cable mobile deployment and retraction device utilizes a temperature protection component, the core innovation of this device, specifically designed to protect the temperature measuring head. The support plate and base provide a stable mounting foundation for the temperature measuring head, preventing it from shaking during movement or deployment.

The sliding fit between the dovetail groove and the dovetail block allows for quick installation and removal of the protective cover. The structure of the protective cover and the embedded slot block ensures a secure lock when not in operation, preventing the protective cover from loosening during transportation or storage. The design of the base frame, elastic blocks, and locking posts ensures the protective cover is effectively fixed, preventing unauthorized sliding that could affect the normal operation of the temperature measuring head.

[0017] 2. This mobile winding and unwinding device for long-distance flexible temperature measuring cables utilizes a winding and unwinding assembly for efficient winding and unwinding of long-distance flexible temperature measuring cables. The mounting frame provides a robust base for the winding mechanism, ensuring that the components do not shift position during operation. The winding motor provides stable and controllable power output, avoiding the uneven tension and tangling risks associated with manual winding and unwinding. The cooperation between the turntable and the central shaft ensures that the cable is evenly arranged during winding and unwinding, reducing bending and wear. Compared to traditional manual reels, this structure significantly improves work efficiency while extending the cable's service life. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides two technical solutions:

[0025] Example 1: A mobile retraction and deployment device for long-distance flexible temperature measuring cables, comprising:

[0026] Stabilizer 1, with a universal brake wheel 2 fixedly connected to one side of stabilizer 1;

[0027] The take-up and rewind assembly 3 is fixedly connected to the top of the stabilizer 1 on one side. The take-up and rewind assembly 3 is used to rotate and rewind the long-distance flexible temperature measuring cable. The cable 4 is fixedly connected to the surface of the take-up and rewind assembly 3.

[0028] Temperature protection component 5 is fixedly connected to one end of cable 4 on one side. It provides protection for the long-distance flexible temperature measuring mechanism. This component is the core innovation of this device, specifically designed to protect the temperature measuring head. The support plate 51 and base 52 provide a stable mounting foundation for the temperature measuring head, preventing it from shaking during movement or storage. The combination of the top cover 54 and the enclosing slot 59 provides all-around physical protection for the temperature measuring head 53 during storage, preventing damage from dust, debris, and impacts. The sliding fit between the dovetail groove 57 and the dovetail block 58 allows for quick installation and removal of the protective cover 510. The structure of the protective cover 510 and the embedded slot 511 ensures a secure lock when not in operation, preventing the protective cover from loosening during transportation or storage. The design of the base frame 512, elastic block 513, and locking post 514 ensures that the protective cover 510 is effectively fixed, preventing it from sliding and affecting the normal operation of the temperature measuring head 53.

[0029] Example 2 differs from Example 1 primarily in that it includes a long-distance flexible temperature measuring cable mobile winding and unwinding device. The winding and unwinding assembly 3 includes a mounting frame 31 fixedly connected to the top of the stabilizer 1. A winding motor 32 is fixedly connected to one side of the mounting frame 31. One end of the output shaft of the winding motor 32 passes through the mounting frame 31 and extends to one side of the mounting frame 31. A turntable 33 is fixedly connected to one end of the output shaft of the winding motor 32. A central shaft 34 is fixedly connected to one side of the turntable 33. The temperature measuring protection assembly 5 includes a support plate 51 fixedly connected to one end of the cable 4. A base 52 is fixedly connected to one side of the support plate 51. A temperature measuring head 53 is fixedly connected to one side of the base 52. A top cover 54 is fixedly connected to one side of the temperature measuring head 53. A through groove is provided on the surface of the top cover 54 to allow a sealing block 59 to pass through. A positioning block 5 is fixedly connected to one side of the top cover 54. 5. The inner wall of the positioning slot 55 is provided with a threaded groove, and a screw 56 is threadedly connected to the inner wall of the positioning slot 55. The surface of the base 52 is provided with a dovetail groove 57, and a dovetail block 58 is slidably connected to the inner wall of the dovetail groove 57. A closing slot 59 is fixedly connected to one side of the dovetail block 58. The inner wall of the closing slot 59 is provided with a threaded groove. A protective cover 510 is fixedly connected to the outer side of the dovetail block 58. An embedded slot 511 is fixedly connected to one side of the protective cover 510. A bottom frame 512 is fixedly connected to the surface of the support plate 51. An elastic block 513 is fixedly connected to one side of the surface of the bottom frame 512. The elastic block 513 has great elasticity. A locking post 514 is fixedly connected to one side of the elastic block 513 through a movable plate. The locking post 514 and the embedded slot 511 are mutually adapted. With the setting of the winding and unwinding assembly 3, this assembly is used to realize the efficient winding and unwinding of long-distance flexible temperature measuring cables. The mounting frame 31 provides a solid mounting base for the winding mechanism to ensure that the position of each component does not shift during operation. The winding motor 32 provides stable and controllable power output, avoiding the risks of uneven tension and tangling caused by manual winding and unwinding. The cooperation between the turntable 33 and the central shaft 34 ensures that the cable is evenly arranged during winding and unwinding, reducing bending and wear. Compared with traditional manual reels, this structure can significantly improve work efficiency and extend the service life of the cable.

[0030] The temperature sensor 53 uses the thermistor principle (RTD), relying on the characteristic that the resistance of a metal (such as platinum) changes with temperature to measure temperature. It has high accuracy and good stability, but the temperature measurement range is relatively narrow (-200℃ to 850℃). Common models include Pt100 and Pt1000.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the stabilizer 1 is pushed to the working position, the universal brake wheel 2 rolls on the ground, the cable 4 is pulled to extend and be placed in the working position, the central shaft 34 rotates simultaneously, the screw 56 on the surface of the rotating positioning slot 55 is rotated, the screw 56 is separated from the closed slot 59, the protective cover 510 is pulled outward, the dovetail block 58 slides along the dovetail groove 57 on the inner surface of the base 52, the temperature measuring head 53 is exposed, the locking pin 514 is pulled, the elastic block 513 on one side of the bottom frame 512 is pressed, and the protective cover 510 is released. When the bottom contacts the top of the tray 51, release the locking pin 514. The locking pin 514 and the embedded slot block 511 engage with each other, and the protective cover 510 is effectively fixed. Then, start the normal temperature measurement operation and wind up the cable 4. Before winding up the cable 4, the above steps need to be reversed to cover and protect the temperature measuring head 53. Turn on the winding motor 32 on one side of the mounting frame 31 to drive the turntable 33 and the central shaft 34 to rotate, and then wind up the cable 4. When the device operation is completed, restore the device to its original state.
