Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology for building energy-saving engineering, and in particular to a mobile cable laying device for building energy-saving engineering. Background Technology

[0002] Mobile layout devices in construction engineering are portable equipment used for rapid and accurate positioning and marking on construction sites. They are mainly used for laying out building axes, elevation lines, and outlines. In the construction process of energy-saving building projects, layout work is a fundamental and crucial procedure, and its accuracy and efficiency directly affect the quality and progress of subsequent construction.

[0003] Traditional wire laying devices often have some shortcomings, such as: poor compatibility with wire laying reels of different sizes, difficulty in quick replacement and fixation, affecting construction efficiency; inability to accurately control the tension of the wire during the laying process, easily leading to problems such as wire tangling and slackness, resulting in reduced laying accuracy; and the fact that mortar is usually spread manually, which can easily cause uneven mortar application and increase the labor intensity of construction workers. To address these issues, we have designed a mobile wire laying device for building energy-saving engineering. Utility Model Content

It can adapt to wire laying reels of various sizes, improve the versatility of the device, guide the wire laying direction, reduce tangling, ensure uniform wire tension, improve wire laying accuracy, and can also spread ash evenly, clear the ash spreading port in real time, ensure continuous and uniform ash spreading and drawing of lines, reduce manual intervention, and reduce labor intensity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile wire-laying device for building energy-saving engineering includes a base and a wire-laying reel. Multiple locking casters are installed at the bottom of the base, and a rotatable turntable is installed at the top of the base. The turntable is equipped with a wire-receiving and wire-laying assembly that fixes the wire-laying reel and drives its rotation. A limiting assembly is fixedly connected to the top of the turntable, allowing the free end of the wire to pass through and adjusting its tension. A bracket is fixedly connected to the bottom of the base, and a dust-spreading box is pulled out and connected within the bracket. A baffle is rotatably connected to the front side of the bracket, abutting against the front wall of the dust-spreading box. A driving assembly for driving the dust-spreading box to spread dust is provided on the base.

[0007] Preferably, a first drive motor is installed at the bottom of the base, and the output shaft of the first drive motor is connected to the turntable.

[0008] Preferably, the take-up and unload assembly includes a guide groove formed on the upper end of the turntable, and two matching guide sliders are slidably connected in the guide groove. The upper ends of the two guide sliders are fixedly connected to vertical plates, and the opposite side walls of the two vertical plates are rotatably connected to conical fixed cylinders. The two conical fixed cylinders are respectively inserted into the inner walls of the two ends of the unload reel, and the conical fixed cylinder on one of the vertical plates is driven to rotate by a second drive motor.

[0009] Preferably, a double-ended screw extending to the outside of the turntable is rotatably connected inside the guide groove, and two opposite threaded sections on the double-ended screw thread through the two guide sliders respectively, and a rotating handle is fixedly connected to the end of the double-ended screw.

[0010] Preferably, the limiting component includes an annular limiting plate fixedly connected to the upper end of the turntable, the free end of the line passes through the annular limiting plate, and a limiting block that abuts against the line is vertically slidably connected inside the annular limiting plate.

[0011] Preferably, the upper end of the limiting block is fixedly connected to a guide rod that slides through the upper side wall of the annular limiting plate, and the upper end of the limiting block is rotatably connected to an adjusting screw, the adjusting screw threaded through the upper side wall of the annular limiting plate.

[0012] Preferably, the ash-spreading box includes a box body and a cover body. The cover body is inserted and closed onto the box body. The bottom of the box body has a through-hole for ash spreading. A T-shaped slide rod is slidably connected through the cover body. The T-shaped slide rod slides through the ash spreading hole. Multiple springs are connected between the T-shaped slide rod and the upper end of the cover body.

[0013] Preferably, the drive assembly includes a third drive motor mounted on the front sidewall of the base via a fixing frame, and an elliptical wheel is mounted at the end of the output shaft of the third drive motor, the elliptical wheel abutting against the upper end of the T-shaped slide bar.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. This building energy-saving project uses a mobile wire-laying device. Rotating the double-headed screw can cause the two vertical plates to move the conical fixed cylinder horizontally. The spacing can be adjusted to accommodate wire-laying reels of different lengths. The anti-slip pad on the outside of the conical fixed cylinder increases the friction with the inner wall of the wire-laying reel, stabilizing the wire-laying reel. At the same time, by adjusting the insertion depth, it can adapt to wire-laying reels of various sizes, improving the versatility of the device. Furthermore, controlling the rotation of the turntable can also adjust the direction of ash spreading.

[0016] 2. The mobile wire laying device used in this building energy-saving project has an annular limiting plate in the limiting component that can guide the wire laying direction and reduce tangling. By rotating the adjusting screw, the limiting block can be moved up and down, which can precisely adjust the pressure force of the limiting block on the wire, thereby controlling the tightness of the wire during the laying process, ensuring uniform wire tension, improving laying accuracy, and providing a reliable baseline for subsequent construction.

[0017] 3. This building energy-saving project uses a mobile line-laying device. The bottom of the ash-spreading box is inclined towards the ash-spreading opening, which facilitates the accumulation of ash in the ash-spreading opening. The third drive motor drives the elliptical wheel to rotate, which, together with the spring, makes the T-shaped slide rod slide up and down in the ash-spreading opening. This not only can evenly control the amount of ash spread, but also clear the ash-spreading opening in real time, avoiding the accumulation and blockage of ash, ensuring continuous and uniform ash-spreading and line drawing, reducing manual intervention, reducing labor intensity, and improving construction efficiency and line drawing quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 A mobile wire laying device for building energy conservation engineering includes a base 1 and a wire laying reel 8. The upper end of the base 1 is equipped with a push handle for moving it. The bottom of the base 1 is equipped with multiple locking casters 2. The locking casters 2 are existing technology and can move the device and fix it. The upper end of the base 1 is equipped with a rotatable turntable 3. The bottom of the base 1 is equipped with a first drive motor. The output shaft of the first drive motor is connected to the turntable 3. The first drive motor drives the turntable 3 to rotate, which can adjust the wire laying direction.

[0027] The turntable 3 is equipped with a take-up and feed assembly that fixes the feed reel 8 and drives it to rotate for feed. The take-up and feed assembly includes a guide groove 4 on the upper end of the turntable 3. Two matching guide sliders are slidably connected within the guide groove 4. Vertical plates 5 are fixedly connected to the upper ends of both guide sliders. The guide sliders slide within the guide groove 4, guiding the two vertical plates 5 and allowing them to move horizontally, closer to or further apart. Conical fixing cylinders 7 are rotatably connected to the opposite side walls of the two vertical plates 5. The two conical fixing cylinders 7 are respectively inserted into the inner walls of both ends of the feed reel 8. The outer wall is provided with anti-slip pads, which can increase the friction between the pay-off reel 8 and the inner wall, thereby stably fixing the pay-off reel 8 in the two conical fixing cylinders 7. By adjusting the depth of the conical fixing cylinders 7 inserted into the pay-off reel 8, pay-off reels 8 of various sizes can be fixed. One of the conical fixing cylinders 7 on the vertical plate 5 is driven to rotate by the second drive motor 9. The second drive motor 9 drives the conical fixing cylinder 7 to rotate, thereby enabling the pay-off reel 8 to rotate for take-up or pay-off work. The two vertical plates 5 on both sides and the conical fixing cylinders 7 can support and fix the pay-off reel 8, ensuring the stability of the pay-off reel 8 during rotation.

[0028] A double-ended screw 6 extending to the outside of the turntable 3 is rotatably connected inside the guide groove 4. Two opposite threaded sections on the double-ended screw 6 are threaded through the two guide sliders respectively. A rotating handle is fixedly connected to the end of the double-ended screw 6. The rotating handle facilitates the rotation of the double-ended screw 6. When the double-ended screw 6 rotates, the two guide sliders can drive the two vertical plates 5 to move closer or further apart under the action of their thread meshing, thereby fixing the wire feeding reels 8 of different lengths.

[0029] A limiting component is fixedly connected to the upper end of the turntable 3, which allows the free end of the line to pass through and adjusts its tension. The limiting component includes an annular limiting plate 10 fixedly connected to the upper end of the turntable 3. The free end of the line passes through the annular limiting plate 10, which guides the line feeding and reduces tangling during feeding. A limiting block 11 that abuts against the line is vertically slidably connected inside the annular limiting plate 10. A guide that slides through the upper side wall of the annular limiting plate 10 is fixedly connected to the upper end of the limiting block 11. The upper end of the rod 12 and the limiting block 11 is rotatably connected to the adjusting screw 13. The adjusting screw 13 is threaded through the upper side wall of the annular limiting plate 10. The guide rod 12 and the adjusting screw 13 work together to restrict the limiting block 11, so that the limiting block 11 can only move up and down. Rotating the adjusting screw 13 can drive the limiting block 11 to move up and down, adjust the magnitude of the pressure force of the limiting block 11 on the line, adjust the tightness of the line during the unwinding process, and reduce the marking deviation caused by the line winding and uneven tension.

[0030] A bracket 14 is fixedly connected to the bottom of the base 1. A dust-spreading box is pulled out of the bracket 14. The front opening of the bracket 14 allows the dust-spreading box to be inserted into the bracket 14 through the front opening. A baffle 21 is rotatably connected to the front of the bracket 14 and abuts against the front wall of the dust-spreading box. Rotating the baffle 21 so that it abuts against the front wall of the dust-spreading box can fix the dust-spreading box in the bracket 14. Rotating the baffle 21 so that it is in a vertical position can remove the dust-spreading box. The rear and bottom of the bracket 14 are hollowed out to facilitate pushing the dust-spreading box out of the bracket 14.

[0031] The ash-spreading box includes a box body 15 and a cover 16. The cover 16 is inserted and closed onto the box body 15. The bottom of the cover 16 is provided with an inner lining plate extending into the box body 15, which facilitates the stable insertion and removal connection between the cover 16 and the box body 15. The bottom of the box body 15 has a ash-spreading opening. A T-shaped slide rod 17 is slidably connected through the cover 16. The T-shaped slide rod 17 slides through the ash-spreading opening. Multiple springs 18 are connected between the T-shaped slide rod 17 and the upper end of the cover 16. The springs 18 are elastic springs, which can push the T-shaped slide rod 17 upward in the natural state. The inner bottom of the box body 15 is inclined towards the ash-spreading opening, so that the ash can move towards the ash-spreading opening and be sprinkled out from the ash-spreading opening. The bottom of the T-shaped slide rod 17 is set with a pointed cone shape. The T-shaped slide rod 17 slides up and down in the ash-spreading opening, which can clear the ash-spreading opening and facilitate the ash to fall from the ash-spreading opening for ash-spreading and marking.

[0032] The base 1 is equipped with a drive assembly for driving the ash-spreading box to spread ash. The drive assembly includes a third drive motor 19 mounted on the front side wall of the base 1 via a fixing bracket. An elliptical wheel 20 is installed at the end of the output shaft of the third drive motor 19. The elliptical wheel 20 abuts against the upper end of the T-shaped slide bar 17. The third drive motor 19 drives the elliptical wheel 20 to rotate, which can work together with the spring 18 to make the T-shaped slide bar 17 slide up and down stably within the ash-spreading port.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] In this utility model, when the mobile wire-laying device for building energy-saving engineering is working, the device is pushed to the place where wire needs to be laid and fixed. The wire-laying reel 8 is placed between the two conical fixed cylinders 7. The rotating handle is turned to make the double-headed screw 6 rotate. Under its thread meshing action, the two guide sliders can drive the two vertical plates 5 to move closer to each other. The two conical fixed cylinders 7 are respectively inserted into the two ends of the wire-laying reel 8, which can stably fix the wire-laying reel 8.

[0035] The yarn is passed through the annular limiting plate 10, which guides the direction of yarn release and reduces tangling during release. The adjusting screw 13 is rotated, and under the thread engagement between the adjusting screw 13 and the top of the annular limiting plate 10, the adjusting screw 13 can drive the limiting block 11 to move up and down, adjusting the tightness of the limiting block 11 against the yarn. The second drive motor 9 drives the conical fixed cylinder 7 to rotate, which can drive the release reel 8 to rotate for releasing the yarn. Similarly, the yarn can also be taken back.

[0036] When it is necessary to sprinkle ash for marking lines, open the cover 16 and put the ash into the box 15. Push the ash box into the bracket 14 and rotate the baffle 21 to fix the ash box. The elliptical wheel 20 abuts against the upper end of the T-shaped slide rod 17. Start the third drive motor 19 to drive the elliptical wheel 20 to rotate. It can work together with the spring 18 to make the T-shaped slide rod 17 slide up and down stably in the ash sprinkling port. The up and down sliding of the T-shaped slide rod 17 in the ash sprinkling port can clear the ash sprinkling port, which is conducive to the ash falling from the ash sprinkling port for ash sprinkling and marking lines, and avoids blockage.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
