Description

Technical Field

[0001] This utility model belongs to the field of land planning technology, and in particular relates to a land planning cable laying and unlaying device. Background Technology

[0002] In fields such as land planning, engineering surveying, building construction, and agricultural land delineation, the operation of taking in and releasing measuring ropes, lines, or cables is a frequent and fundamental task. Traditional wire taking in and releasing devices typically consist of simple components such as take-up rollers, supports, and cranks, and their function is limited to the storage and release of cables, lacking the ability to accurately measure the length of the wire taken in and released.

[0003] Currently, when workers need to measure cable length, they mainly rely on the following two methods: Manual memory and estimation: Operators estimate the length by memorizing the number of rotations of the take-up roller and multiplying it by the circumference of the take-up roller. This method is very prone to huge errors due to distraction or misremembering the number of rotations, has poor reliability, and cannot be used for accurate measurement. External electronic measuring equipment: Some solutions employ external electronic meter counters, encoders, or GPS-based ranging devices. While these devices offer high accuracy, they have significant drawbacks: First, they are expensive, increasing project budgets; second, electronic equipment relies on power supplies, resulting in insufficient battery life in unpowered environments, and is susceptible to harsh conditions such as rain and sandstorms, exhibiting poor reliability and adaptability. To address these issues, a land planning line laying and unlaying device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a land planning and layout device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a land planning line laying and take-up device, comprising a base, a first mounting frame, and a vertical plate. Both the first mounting frame and the vertical plate are fixedly mounted on the upper surface of the base. A motor is fixedly mounted on one surface of the vertical plate, and a drive wheel is fixedly connected to the output end of the motor. One surface of the drive wheel is fixedly connected to a take-up and take-up roller via a connecting rod. The take-up and take-up roller is installed inside the first mounting frame. The motor drives the take-up and take-up roller to rotate clockwise to lay out the line and counterclockwise to take back the line. A connecting shaft is fixedly connected to the other end of the take-up and take-up roller, and a counting mechanism is fixedly connected to one end of the connecting shaft. The counting mechanism includes at least one mechanical reset counter. When the take-up and take-up roller rotates, it drives the counting mechanism to rotate via the connecting shaft to calculate the length of the line laid out and taken back.

[0006] Preferably, a second mounting bracket is fixedly provided on the upper surface of the base. The second mounting bracket is provided with a reciprocating lead screw and a limiting guide rail. The limiting guide rail is fixedly connected to the second mounting bracket. A driven wheel is fixedly connected to one end of the reciprocating lead screw. A transmission belt is connected between the driving wheel and the driven wheel. A moving ring is provided on the circumferential side of the reciprocating lead screw. A guide rod and a limiting rod are fixedly connected to the circumferential side of the moving ring. A limiting wheel is connected to the bottom end of the limiting rod. An inclined plate is fixedly provided in the guide rod. Two guide rods are fixedly connected to the upper surface of the inclined plate.

[0007] Preferably, the counting mechanism includes a protective box, inside which a worm and a worm wheel are provided. One end of the worm is fixedly connected to a connecting shaft, and a drive shaft is fixedly connected to one surface of the worm wheel. A counting shaft is provided on one side of the mechanical reset counter, and the drive shaft is fixedly connected to the counting shaft. A connecting plate is fixedly provided on one side of the protective box, and the mechanical reset counter is fixedly mounted on the upper surface of the connecting plate.

[0008] Preferably, the limiting wheel is rotatably connected to the limiting rod, and the reciprocating screw is rotatably connected to the second mounting bracket.

[0009] Preferably, the limiting wheel and the limiting guide rail are in frictional engagement.

[0010] Preferably, the drive shaft is rotatably connected to the protective box, and the worm gear meshes with the worm wheel.

[0011] This utility model has the following beneficial effects: 1. This utility model realizes the automatic and accurate measurement of the take-up and unwinding length. Specifically, by setting a worm gear fixed coaxially with the take-up and unwinding rollers, and a worm wheel meshing with the worm gear and driving the mechanical reset counter, the number of rotations of the take-up rollers is successfully converted into the measurement of the cable length. This structure has precise transmission, no risk of slippage, and fundamentally solves the problem of easy errors in manual counting. The measurement results are accurate and reliable. 2. The entire measuring unit of this utility model is a purely mechanical structure and does not contain any electronic components. Its performance is not affected by harsh outdoor environments such as rain, sand, and humidity, and it does not require a power supply. It solves the technical problems of electronic measuring equipment being prone to failure and having short battery life outdoors, and is particularly suitable for long-term operation under conditions without power supply. 3. This utility model can guide the cable and scrape off dust and impurities adhering to the cable surface during cable winding and unwinding. Specifically, it is equipped with a reciprocating screw, a moving ring, and a guide rod. During winding and unwinding, the cable is placed between two guide rods. The winding and unwinding roller rotates, which drives the reciprocating screw to rotate through the transmission mechanism. The moving ring then drives the guide rod to move, so that the position of the cable always corresponds to the position of the winding and unwinding roller, ensuring the neatness of the cable winding and unwinding. In addition, the cable rubs against the guide rod during the winding and unwinding process, thereby scraping off the dust and impurities adhering to the cable surface.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figures 1-4 As shown, this utility model is a land planning and layout device, including a base 1, a first mounting frame 2 and a vertical plate 4. The base 1 serves as the supporting foundation for the entire device and is usually made of metal sheet to ensure overall stability. The first mounting frame 2 and the vertical plate 4 are fixed to the upper surface of the base 1 by welding or bolt connection. A motor 5 is fixedly mounted on one surface of the vertical plate 4. The motor 5 is preferably a DC motor or servo motor with a reducer that can rotate in both directions to control the speed and direction of the take-up and undo roller 6. The output end of the motor 5 is fixedly connected to a drive wheel 7. One surface of the drive wheel 7 is fixedly connected to the take-up and undo roller 6 through a connecting rod. The take-up and undo roller 6 is installed in the first mounting frame 2 and is used to wind the cable. The motor 5 drives the take-up and undo roller 6 to rotate clockwise to realize the function of undoing the cable and to rotate counterclockwise to realize the function of taking up the cable. The other end of the take-up / delivery roller 6 is fixedly connected to a connecting shaft 23. One end of the connecting shaft 23 is fixedly connected to a counting mechanism. The counting mechanism includes at least one mechanical reset counter 11. The counting mechanism includes a protective box 10, which contains a worm gear 24 and a worm wheel 25. The worm gear 24 meshes with the worm wheel 25. The protective box 10 is used to protect the internal worm gear 24 and worm wheel 25 from dust and impact. One end of the worm gear 24 is fixedly connected to the connecting shaft 23. The worm gear 24 rotates synchronously with the take-up / delivery roller 6. A drive mechanism is fixedly connected to one surface of the worm wheel 25. The drive shaft 19 is rotatably connected to the protective box 10. The mechanical reset counter 11 has a counting shaft 20 on one side. The drive shaft 19 and the counting shaft 20 are fixedly connected by a coupling or set screw, thereby transmitting power to the counter. The protective box 10 has a connecting plate 18 fixedly installed on one side. The mechanical reset counter 11 is fixedly installed on the upper surface of the connecting plate 18. Its display window should face a direction that is easy for the operator to observe. When the take-up and release roller 6 rotates, it will drive the counting mechanism to rotate through the connecting shaft 23 to calculate the length of the take-up and release line.

[0019] A second mounting bracket 3 is fixedly mounted on the upper surface of the base 1. A reciprocating lead screw 12 and a limiting guide rail 15 are housed within the second mounting bracket 3. The reciprocating lead screw 12 is rotatably connected to the second mounting bracket 3, and the limiting guide rail 15 is fixedly connected to the second mounting bracket 3. The length of the limiting guide rail 15 matches the effective stroke of the reciprocating lead screw 12. A driven wheel 8 is fixedly connected to one end of the reciprocating lead screw 12. A transmission belt 9 connects the driving wheel 7 and the driven wheel 8, thus forming a belt drive mechanism that transmits the power of the motor 5 to the reciprocating lead screw 12. A moving ring 1 is provided on the circumferential side of the reciprocating lead screw 12. 3. A wire seat 17 and a limiting rod 14 are fixedly connected to the circumferential side of the moving ring 13. A limiting wheel 16 is connected to the bottom end of the limiting rod 14. The limiting wheel 16 is rotatably connected to the limiting rod 14. The groove of the limiting wheel 16 is in frictional engagement with the track of the limiting guide rail 15, thereby limiting and guiding the movement path of the moving ring 13 and preventing it from rotating with the reciprocating screw 12. An inclined plate 21 is fixedly provided inside the wire seat 17. Two wire rods 22 are fixedly connected to the upper surface of the inclined plate 21. A wire channel is formed between the two wire rods 22 to guide and limit the position of the cable.

[0020] Working principle: In operation, motor 5 is started, and motor 5 drives the take-up and untake-up rollers 6 to rotate via the drive wheel 7. When motor 5 rotates clockwise, the take-up and untake-up rollers 6 release the cable, realizing the cable unloading function; when motor 5 rotates counterclockwise, the take-up and untake-up rollers 6 wind up the cable, realizing the cable take-up function. Simultaneously with motor 5 driving the take-up and untake-up rollers 6, power is transmitted to the reciprocating screw 12 via the drive wheel 7, transmission belt 9, and driven wheel 8, causing it to rotate synchronously. The rotational motion of the reciprocating screw 12 is converted into the linear reciprocating motion of the moving ring 13 via a screw thread. The moving ring 13 drives the guide seat 17 and guide rod 22 on it to move axially along the reciprocating screw 12. The limiting wheel 16 at the bottom of the guide rod 14 rolls along the limiting guide rail 15, providing stable guidance and support for the movement of the moving ring 13 and preventing it from jamming. Through this structure, the guide rod 22 guides the cable to be wound or released evenly and orderly on the take-up and release roller 6, effectively avoiding the tangled and jammed cable caused by the concentrated accumulation of cable in a certain section, ensuring the neatness of take-up and release. At the same time, when the cable passes through the guide rod 22, its surface will rub against the guide rod 22, thereby scraping off some of the dust and impurities, playing a certain cleaning role. When the take-up and release roller 6 rotates, it drives the worm gear 24 to rotate synchronously through the connecting shaft 23. The worm gear 24 drives the worm wheel 25 meshing with it to rotate. The high reduction ratio of the worm gear pair converts the multiple rotations of the take-up and release roller 6 into a small number of rotations of the worm wheel 25. The worm wheel 25 transmits the rotational motion to the counting shaft 20 of the mechanical reset counter 11 through the drive shaft 19, driving the internal counting mechanism to count. The mechanical reset counter 11 converts the number of rotations of the worm wheel 25 into a length value for direct display. Since the circumference of the take-up and release roller 6 is a fixed value, by precisely calculating and selecting the transmission ratio between the worm gear 25 and the worm 24, the displayed value of the counter can be made to correspond precisely with the actual length of the take-up and release of the cable (for example, display 1 represents the actual release or retraction of 1 meter of cable), thus achieving accurate measurement. When a reset is required, the mechanical reset counter 11 can be disassembled, and the reset button on the mechanical reset counter 11 can be manually operated to return the displayed value to zero.
