Description

Technical Field

[0001] The utility model belongs to the technical field of wire reel discs, and in particular relates to a power-assisted wire reel disc device for counting and communicating wires. Background Art

[0002] In the process of continuous development and improvement of various construction projects in my country, there are still some dangerous factors of small-diameter deep wells, whether in remote rural areas or some industrial sites. Due to disrepair, lack of funds and energy for operation and maintenance, these deep wells are often not backfilled or closed in time, which is a great hidden danger for children and the elderly with poor safety awareness. In recent years, many accidents of falling into wells and being trapped have occurred. At the same time, shallow coal resources are gradually exhausted due to mining and utilization, resulting in the gradual deepening of mining depth. The average mining depth of most mines has exceeded 800m. Due to the deep mining depth and the complex geological conditions of the tunnels, the proportion of roof collapse and water seepage accidents in the coal mining process has increased. Once an underground production safety accident occurs, drilling vertical rescue becomes an effective rescue method.

[0003] At present, life information detection systems are used in deep well rescue and mine drilling vertical rescue. The line reel in the life information detection system usually only has the function of reeling and releasing the line. When the well is deep, it is difficult to clearly know the reeling and releasing distance. Moreover, the reeling and releasing process uses proportional manual transmission, which is time-consuming and labor-intensive. There is a lack of precise control and power-assist design during the reeling and releasing process. The existing automatic control reel has poor environmental applicability and low stability in harsh environments. It is difficult to meet the requirements of line reel stability, controllability and reeling and releasing length accuracy during the rescue process. Utility Model Content

[0042] Example 3

[0043] On the basis of Example 2, Figure 5 As shown, the power-assisted brake module in the power-assisted reel-type wire counting and communication wheel device of this embodiment includes a driven gear 14 sleeved on the load-bearing middle shaft 10, and the driven gear 14 is fixedly connected to the winding wheel 5 by bolts. The driven gear 14 is also meshed with the driving gear 13, and the diameter ratio of the driving gear and the driven gear is 1:2. The purpose of power-assisted wire reeling is achieved by changing the transmission ratio. The load-bearing middle shaft 10 passes through the rear belt base bearing 11, the driven gear 14, the winding wheel 5 and the front belt base bearing 29 to achieve coaxial and stable rotation of the wheel.

[0044] A short middle shaft 34 is axially passed through the axis center of the driving gear 13, and a turntable 16 is fixedly connected to the end of the short middle shaft 34 away from the driving gear 13, and a handle 17 is vertically fixedly connected to the side of the turntable 16 away from the driving gear 13, so that the staff can easily rotate the turntable 16.

That is, the driven gear limiter 20 limits the rotation of the winding wheel 5 by shrinking into the limiting hole 19.

[0047] Example 4

[0048] On the basis of Example 3, Figure 6 As shown, the counting module in the power-assisted retractable counting communication wheel device of this embodiment includes a counting roller bracket consisting of a pair of fixed brackets 22, a movable bracket a23 and a movable bracket b25, and the pair of fixed brackets 22 are fixedly connected to the wheel support frame 1 by fixing bolts 38.

[0049] A rubber counting roller 24 is arranged between the movable bracket a23 and the movable bracket b25, and the cable contacts the rubber counting roller 24. Limiting springs 27 are connected to the fixed brackets 22 on both sides. The end of the limiting spring 27 away from the fixed bracket 22 is respectively connected to the movable bracket a23 and the movable bracket b25. The movable range of the rubber counting roller 24 is limited by the tension of the limiting spring 27 to ensure that the cable and the rubber counting roller 24 maintain continuous soft friction.

[0050] Furthermore, two ends of the rubber counting roller 24 are respectively nested and connected with the movable bracket a23 and the movable bracket b25 through bearings, so that the rubber counting roller 24 can rotate freely relative to the movable bracket a23 and the movable bracket b25.

[0051] One end of the rubber counting roller 24 close to the movable bracket b25 is connected to a coupling a26, and the other end of the coupling a26 is connected to an encoder 28. The encoder 28 is connected to the monitoring terminal through an external data transmission line of the signal transmission port 37, and the encoder 28 is fixedly connected to the movable bracket b25.

[0052] Since the life information detection device connected by the cable has a certain weight, the cable is always kept in a straightened state, and the cable is closely fitted with the rubber counting roller 24. In addition, the limit spring 27 limits the range of movement of the rubber counting roller 24 through the spring tension, ensuring that the cable and the rubber counting roller 24 maintain continuous soft friction. When the cable is retracted or released, the friction force drives the rubber counting roller 24 to rotate, and the rubber counting roller 24 drives the encoder 28 through the coupling a26 to achieve real-time counting of the retracted and released wires.
