Description

Technical Field

[0001] This utility model belongs to the field of engineering construction technology, and more specifically, it relates to a wire take-up and release device for engineering surveying. Background Technology

[0002] Engineering surveying plays a crucial role in engineering construction. Surveying equipment is used to verify data during construction, reduce errors, and ensure construction quality. Layout surveying is frequently required during engineering surveying. Existing layout equipment typically uses a winding roller to wind and rewind the surveying line. During the measurement process, the surface of the surveying line easily accumulates dust and dirt. Directly winding the line onto the roller results in a large amount of dust affecting the uniformity of the winding, impacting subsequent layout use, and ultimately shortening the lifespan of the surveying line over time.

[0003] Existing technology includes a device titled "A Cable Rewinding and Laying Device for Engineering Measurement with Intelligent Sensors," with publication number CN120397845A. This technology discloses a cable rewinding and laying device for engineering measurement with intelligent sensors, relating to the field of engineering measurement technology. The present invention includes a housing with a leveling device at the bottom. The leveling device includes a laser, a support, a level detector, and a telescopic leg. The laser is fixed to the top surface of the housing, the support is fixed to the bottom surface, the level detector is fixed to the front of the support, and the telescopic leg is fixed to the bottom of the support. The present invention, through the leveling device, allows the laser, support, level detector, and telescopic leg to work together. When using the cable rewinding and laying device, the level of the laser is observed by the level detector. If the leveling device is not level enough, the telescopic leg is activated, adjusting the level of the support, which in turn adjusts the level of the housing, keeping the cable rewinding and laying device level. This prevents the device from tipping over during use and avoids inaccurate laying results due to tilting. However, this technology does not address the technical problems and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an engineering measurement wire feeding and take-up device that is simple in structure, effectively cleans the dust and dirt on the surface of the measuring wire during take-up while ensuring convenient and quick wire feeding and take-up, avoids the impact of dirt and dust on the uniformity of wire winding and subsequent wire feeding, improves the service life of the wire harness, and can also achieve the collection and discharge of clean dust and dirt.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a wire take-up and release device for engineering measurement. The device box is equipped with a roller brush, and the side of the device box is equipped with an adjustment port, which includes a U-shaped groove and a U-shaped groove. The roller brush is installed in the adjustment port. The bottom of the device box is equipped with a dust collection baffle. A push plate is provided on one side of the bottom of the device box. The push plate is connected to an electric telescopic rod, and the electric telescopic rod is fixedly connected to the device box.

[0006] Each end of the first roller brush is movably connected to the side of the device housing via a connecting shaft, and each end of the second roller brush is movably installed in the corresponding adjustment port on the side of the device housing via a connecting shaft.

[0007] The device housing has two upright plates on its bottom surface, and a winding roller is movably installed between the two upright plates. A motor is installed on the outside of one of the upright plates, and the drive shaft of the motor is fixedly connected to one end of the winding roller.

[0008] The roller brush one and roller brush two are arranged in parallel, with roller brush two located directly above roller brush one. The bottom of U-shaped groove one is at a lower horizontal level than the bottom of U-shaped groove two. A limiting cylinder is installed on the side of the device box directly above U-shaped groove one.

[0009] The device housing has two upright plates on its bottom surface, and a reciprocating lead screw is movably installed between the two upright plates. A drive belt is fitted onto the drive wheel of the motor drive shaft and the driven wheel of the reciprocating lead screw.

[0010] The reciprocating screw is located between the winding roller and the second brush.

[0011] The reciprocating lead screw has a movable guide seat. A horizontal plate is provided on the bottom surface of the device box below the reciprocating lead screw. A sliding groove is provided on the upper surface of the horizontal plate. The slider fixed at the lower part of the guide seat is movably engaged in the sliding groove.

[0012] Two vertical plates are fixed to the bottom of the device box, and two vertical plates are fixed to the bottom of the device box.

[0013] The discharge port is located on the side of the device housing facing the push plate.

[0014] The device housing has a wire outlet and a ray hole at the front, and an infrared lamp on the inner side of the rear of the device housing.

[0015] The working principle and beneficial effects of this utility model are as follows: The engineering surveying wire winding and unwinding device of this utility model is structurally designed such that the device housing forms the basis for the related components. Two rollers, one and two, are parallel. The measuring wire (wire bundle) passes between rollers one and two. After measurement, when the measuring wire is not in use, it is wound onto the winding roller. When in use, the motor rotates in one direction, driving the winding roller to unwind the wire. Simultaneously, the connecting shafts at both ends of roller two are pushed, moving roller two into the U-shaped groove two of the adjustment port. At this point, roller two does not contact roller one, avoiding interference with the measurement. Friction is generated by the wire to avoid affecting the stability of the wire feeding; when the wire is wound up, the motor reverses and the reciprocating screw rotates under the drive belt, causing the guide seat to move in the direction of the slide groove to guide the wire harness. The measuring wire is evenly wound onto the winding roller. At the same time, the second roller brush is clamped into the U-shaped groove of the first roller brush along the adjustment port. The second roller brush is close to the first roller brush. The wire harness passing between the two roller brushes is swept to remove dust and dirt. The dust and dirt fall to the bottom of the box and are pushed out of the device box from the discharge port by the push plate driven by the electric telescopic rod. The device of this utility model (1) allows the position of the roller brush 2 to be moved by adjusting the two U-shaped grooves of the port. When the wire is released, the wire bundle does not contact the roller brush 2, reducing friction and making the wire release faster and more stable. When the wire is taken back, the roller brush 2 is moved directly above the roller brush 1. The wire bundle passes through the roller brush 1 and the roller brush 2 to clean off the dust and dirt, avoiding affecting the stability of the next wire release and extending the service life. (2) The electric telescopic rod 7 extends to push the push plate to move, which can push the dust and dirt that fall at the bottom of the device box to the outside of the device box.

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 -Appendix Figure 4 As shown, this utility model is a wire take-up and release device for engineering surveying. A roller brush 3 is installed inside the device housing 1. An adjustment port 5 is provided on the side of the device housing 1. The adjustment port 5 includes a U-shaped groove 24 and a second U-shaped groove 25. The roller brush 4 is installed inside the adjustment port 5. A dust collection baffle 6 is located on the bottom surface of the device housing 1. A push plate 8 is provided on one side of the bottom surface of the device housing 1. The push plate 8 is connected to an electric telescopic rod 7, which is fixedly connected to the device housing 1. The above structure addresses the shortcomings of the prior art and proposes an improved technical solution. In the structural setup, the device housing 1 serves as the foundation for the related components. Brush 1 (3) and Brush 2 (4) are parallel. The measuring wire (wire harness) passes between Brush 1 (3) and Brush 2 (4). After measurement, when not in use, the measuring wire is wound onto the winding roller 13. When in use, the motor 12 rotates in one direction, causing the winding roller 13 to release the wire. Simultaneously, the connecting shafts at both ends of Brush 2 (4) are pushed, moving Brush 2 (4) into the U-shaped groove 25 of the adjusting port 5. At this point, Brush 2 (4) does not contact Brush 1 (3), preventing friction on the measuring wire and avoiding interference. Stability of wire feeding; When winding, motor 12 reverses, and reciprocating screw 15 rotates under the drive of drive belt 14, causing guide seat to move in the direction of slide groove 18 to guide the wire harness. The measuring wire is evenly wound onto winding roller 13. At the same time, roller brush 2 4 is clamped into the U-shaped groove 24 of roller brush 1 3 along the adjustment port 5. Roller brush 2 is close to roller brush 1. The wire harness passing between the two roller brushes is swept away of dust and dirt. The dust and dirt fall to the bottom of box 1 and are pushed out of the device box 1 by push plate 8 driven by electric telescopic rod 7. The device of this utility model (1) allows the position of the second roller brush to be moved by adjusting the two U-shaped grooves of the port. When releasing the wire, the wire bundle does not contact the second roller brush, reducing friction and making the wire release faster and more stable. When retracting the wire, the second roller brush is moved directly above the first roller brush. The wire bundle passes through the first and second roller brushes to clean off dust and dirt, avoiding affecting the stability of the next wire release and extending the service life. (2) The electric telescopic rod 7 extends to push the push plate to move, which can push the dust and dirt that fall at the bottom of the device box to the outside of the device box. The wire release and take-up device for engineering measurement described in this utility model has a simple structure. Under the premise of ensuring convenient and quick wire release and take-up, it effectively cleans the dust and dirt on the surface of the wire during take-up, avoiding the dirt and dust from affecting the uniformity of the wire bundle winding and affecting the subsequent wire release, improving the service life of the wire bundle, and also realizing the collection and discharge of clean dust and dirt.

[0018] Each end of the roller brush 3 is movably connected to the side of the device housing 1 via a connecting shaft, and each end of the roller brush 4 is movably installed in the corresponding adjustment port 5 on the side of the device housing 1 via a connecting shaft. In this structure, the connection position between the roller brush 1 and the device housing is fixed, and the roller brush 1 can only rotate relative to the device housing without moving its position. The roller brush 2 can switch between two states. During wire feeding, the roller brush 2 is located in the U-shaped groove 25, away from the roller brush 3, and does not contact the measuring line, ensuring smooth wire feeding. During wire retraction, the roller brush 2 is located in the U-shaped groove 24, close to the roller brush 1, and contacts the measuring line to clean dust and dirt. The cleaned dust and dirt fall onto the device housing position on the side of the dust collection baffle 6, and then the electric telescopic rod 7 extends to push the push plate to move, thus pushing the dust and dirt to the outside.

[0019] The device housing 1 has two upright plates 10 on its bottom surface, and a winding roller 13 is movably installed between the two upright plates 10. A motor 12 is installed outside one of the upright plates 10, and the drive shaft of the motor 12 is fixedly connected to one end of the winding roller 13. In this structure, the two upright plates 10 are used to install the winding roller, on which the measuring line is wound, enabling the winding and unwinding of the measuring line.

[0020] The roller brush 3 and roller brush 4 are arranged in parallel, with roller brush 4 positioned directly above roller brush 3. The bottom of U-shaped groove 24 is horizontally lower than the bottom of U-shaped groove 25. A limiting cylinder 23 is installed on the side of the device housing 1 directly above U-shaped groove 24. In this structure, when roller brush 2 is within U-shaped groove 24, the limiting cylinder extends, restricting the position of roller brush 4 and ensuring that roller brush 4 can only rotate and cannot leave U-shaped groove 24. When roller brush 2 leaves U-shaped groove 24, the limiting cylinder retracts, no longer preventing roller brush 2 from leaving.

[0021] The top of the device housing 1 is fixedly connected to a cover plate with screws, and a handle 2 is provided on the cover plate for easy movement of the device. Two upright plates 11 are provided on the bottom surface of the device housing 1, and a reciprocating lead screw 15 is movably mounted between the two upright plates 11. A drive belt 14 is fitted onto the drive wheel of the motor 12's drive shaft and the driven wheel of the reciprocating lead screw 15. The reciprocating lead screw 15 is located between the winding roller 13 and the roller brush 4. A wire guide seat 16 is movably mounted on the reciprocating lead screw 15. A horizontal plate 19 is provided on the bottom surface of the device housing 1 below the reciprocating lead screw 15, and a sliding groove 18 is provided on the upper surface of the horizontal plate 19. A slider 17 fixed at the lower part of the wire guide seat 16 is movably engaged in the sliding groove 18. In this structure, the two upright plates 11 are used to mount the reciprocating lead screw, which rotates under the action of the drive belt. When the reciprocating lead screw rotates, it drives the wire guide seat 16 to move back and forth, guiding the measuring line. This ensures that the measuring line can be evenly wound on the winding roller, avoiding excessive winding in local areas. Specifically, the reciprocating screw drives the guide wire seat to wind the wire onto the winding roller, ensuring uniform winding of the wire bundle. The motor 12 rotates simultaneously, driving the winding roller 13 and the reciprocating screw 15 to rotate, resulting in rapid and stable winding. The measuring wire has a lead end left outside the wire outlet 20 for easy access, allowing for reliable pulling of the lead end to release the measuring wire during the next unwinding process.

The winding roller is perpendicular to the first vertical plate and parallel to the bottom surface of the device housing. Two vertical plates 21 are fixed vertically to the bottom surface of the device housing 1. The reciprocating screw is perpendicular to the second vertical plate and parallel to the bottom surface of the device housing.

[0023] A discharge port 9 is provided on the side of the device housing 1 facing the push plate 8. With the above structure, when the push rod 8 moves toward the discharge port 9, it can push the dust and dirt that fall on the bottom surface of the device housing 1 to the position of the discharge port 9, and thus push them out of the device housing 1 from the position of the discharge port 9.

[0024] The device housing 1 has a wire outlet 20 and a ray aperture 22 at its front, and an infrared lamp 21 on the inner rear side of the housing 1. In this structure, the detection component includes an infrared lamp 21 and a ray aperture 22. The infrared lamp 21 is fixed to the inner wall of the housing 1, and the ray aperture 22 is located above the wire outlet 20, used to emit stable reference light. In this structure, the infrared lamp 21 emits stable light as a reference line during measurement, helping the operator to more accurately locate the measurement point; the ray aperture 22 is used for the light emitted by the infrared lamp 21 to exit.
