Description

Technical Field

[0001] This utility model relates to the field of engineering construction layout, and in particular to a layout device for engineering construction. Background Technology

[0002] In the field of engineering construction, the production activities in the engineering construction implementation phase are the construction process of various buildings, including foundation construction, main structure construction, roof construction, decoration construction, etc. During the construction process, a large amount of wiring materials (nylon wire, steel wire, ink line) are needed. When workers are carrying out wiring construction, they usually need to use wiring devices to release the wire rolls.

[0003] In existing technologies, the existing engineering construction line-laying devices mainly consist of a base, a fixed bracket, a winding drum (including a limit baffle), and a manual / electric drive motor, which work together to achieve the line-laying work. However, in actual use, there is a lot of mud, sand, gravel, and cement slurry at the construction site. During the dragging process, the line material (especially nylon line and ink line) is prone to sticking with impurities. If it is not cleaned before winding, the impurities will be embedded in the line fibers or attached to the surface of the line material. Over time, this will lead to wear and breakage of the line material, thus affecting the performance.

[0004] Therefore, it is necessary to propose a line-laying device for engineering construction to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a wire laying device for engineering construction, so as to solve the problem that when the wire is used on site, it is easy for impurities such as mud, sand, gravel and cement slurry to stick to it, and the direct winding will cause the wire to wear and break.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a line-laying device for engineering construction, comprising a movable platform, a drive motor fixedly connected to the upper surface of the movable platform, a pulley assembly provided at the output end of the drive motor, a reciprocating screw mechanism provided on the upper surface of the movable platform, the reciprocating screw rotation shaft of the reciprocating screw mechanism being fixedly connected to a pulley on the side of the pulley assembly away from the output end of the drive motor, and a cleaning mechanism provided on the upper surface of the movable platform; The cleaning mechanism includes a fixed base, which is fixedly connected to the upper surface of the moving platform, and a flexible cleaning brush is rotatably connected inside the fixed base.

[0007] Preferably, the cleaning mechanism further includes a mounting frame, which is fixedly connected to the outer surface of the fixed base. A first gear is rotatably connected to the inner side of the mounting frame, and a second gear is rotatably connected to the inner side of the mounting frame. The first gear and the second gear are rotatably connected. The axis of the second gear is fixedly connected to the rotating shaft of the flexible cleaning brush. The first gear is fixedly connected to the reciprocating screw rotating shaft of the reciprocating screw mechanism and is coaxially arranged.

[0008] Preferably, the output end of the drive motor is fixedly connected to a take-up drum, and a rotating pressure block is externally threaded onto the placement shaft on the take-up drum.

[0009] Preferably, the upper surface of the moving part of the reciprocating screw mechanism is threaded with a first guide wheel, and the side of the moving part of the reciprocating screw mechanism away from the winding drum is rotatably connected with a second guide wheel.

[0010] Preferably, one side of the second guide wheel contacts the cleaning part of the flexible cleaning brush.

[0011] Preferably, the lower surface of the mobile platform is fixedly connected with self-locking casters.

[0012] The technical effects and advantages of this utility model are as follows: 1. In this utility model, the cleaning mechanism is set up so that the flexible cleaning brush rotates under the action of the second gear transmission while the wire is being wound up. This cleans the wire recovered from the construction site and removes the cement slurry, dust and other impurities remaining on the surface of the wire. This prevents impurities from embedding into the wire fibers or adhering to the surface and causing wear on the wire during the winding process, thus extending the service life of the wire. 2. Furthermore, with the first and second guide wheels in place, when using the wire, it must be wound from the top of the first guide wheel and out from the bottom of the second guide wheel. The movement trajectory of the wire is limited by the cooperation of the two guide wheels to prevent the wire from deviating and tangling. Attached Figure Description

Detailed Implementation

[0018] This utility model provides a wire laying device for engineering construction, as shown in Figures 1-4, which aims to solve the problem that when the wire is used on site, it is easy for impurities such as mud, sand, gravel, and cement slurry to stick to it, and direct winding will cause the wire to wear and break.

[0019] The wire laying device used in this construction project includes a movable platform 1, which serves as the basic support structure. A self-locking caster wheel 2 is fixedly connected to the lower surface of the movable platform 1. A drive motor 3 is bolted to the front of the upper surface of the movable platform 1. One end of its output shaft is fixedly connected to a take-up drum 4 via a flat key. The outer surface of the take-up drum 4's placement shaft is machined with external threads, which are compatible with the internal threads of a rotating pressure block 5. After the rotating pressure block 5 is tightened, it can clamp the wire drum between the end face of the take-up drum 4 and the pressure block, preventing the wire drum from slipping or shifting during winding or laying. The output shaft of the drive motor 3 is fitted with a drive pulley set 6, which is connected to the driven pulley via a transmission belt, realizing the branched transmission of power.

[0020] The reciprocating screw mechanism 10 consists of a reciprocating screw, a moving block, a guide rod, a bracket, and bearings. The reciprocating screw is the core transmission component and is in movable cooperation with the moving block. The moving block is in sliding cooperation with the guide rod, and the guide rod is fixed on the bracket. The bracket is used for fixed installation. The bearings reduce the rotational friction of the screw. Driven by the motor, the rotation of the screw can drive the moving block to reciprocate along the axial direction to guide the wire. This is existing technology and will not be described in detail here.

[0021] The reciprocating screw mechanism 10 is fixed to the upper surface of the moving table 1 by the brackets on both sides and is located behind the take-up drum 4. One end of its reciprocating screw rotation shaft is fixedly connected to the driven wheel of the pulley group 6 through a coupling, and can rotate synchronously under the drive of the drive motor 3. The upper surface of the moving block of the reciprocating screw mechanism 10 is connected to the bracket of the first guide wheel 7 through a threaded hole. The side of the moving block away from the take-up drum 4 is rotatably connected to the second guide wheel 8 through a rotating shaft. When the wire is used, it needs to be wound from the top of the first guide wheel 7 and out from the bottom of the second guide wheel 8. The movement trajectory of the wire is limited by the cooperation of the two guide wheels to avoid the wire from deviating and tangling.

[0022] The cleaning mechanism 9 is welded to the upper surface of the moving table 1 via a fixed base 91 and is located on the side of the second guide wheel 8 away from the take-up drum 4. A mounting frame 92 is welded to the outer wall of the fixed base 91. The inner side of the mounting frame 92 is rotatably connected to the first gear 93 and the second gear 94 via bearings. The two gears mesh with each other. The first gear 93 is fixed to the reciprocating screw rotation shaft of the reciprocating screw mechanism 10 by a set screw and is coaxial with the rotation shaft. The axis of the second gear 94 is fixedly connected to the rotation shaft of the flexible cleaning brush 95 via a flat key. The bristles of the flexible cleaning brush 95 extend to the inner side of the fixed base 91 and contact the side wall of the second guide wheel 8 to ensure that the wire can fit tightly with the bristles when passing through the second guide wheel 8.

[0023] During the use of the device, first, place the spool of the wire to be used, such as nylon wire or ink wire, onto the placement shaft of the take-up drum 4, and rotate the pressure block 5 clockwise until the pressure block is in close contact with the end face of the spool to fix the spool and prevent the spool from loosening during unwinding, which would cause unstable wire tension.

[0024] Pull the free end of the wire and pass it around the top of the first guide wheel 7 and the bottom of the second guide wheel 8 in sequence, so that the wire fits against the side wall of the second guide wheel 8. At this time, the wire naturally comes into contact with the bristles of the flexible cleaning brush 95.

[0025] The entire device is pushed and moved to the designated position by the self-locking casters 2. The drive motor 3 is started, which drives the take-up drum 4 to rotate. The wire is gradually released from the take-up drum 4 to meet the construction wire length requirements. At the same time, the drive motor 3 drives the screw of the reciprocating screw mechanism 10 to rotate through the pulley group 6. This causes the moving block to move back and forth along the screw axis with the first guide wheel 7 and the second guide wheel 8, ensuring that the wire is released evenly and avoiding wire knots caused by local accumulation. The free end of the wire is then manually pulled to move to the designated position.

[0026] During the winding process, the pulley assembly 6 continuously drives the reciprocating screw mechanism 10. The moving block, along with the first guide wheel 7 and the second guide wheel 8, reciprocates, guiding the wire to be evenly wound onto the spool of the winding drum 4, preventing the wire from overlapping and being squeezed. Simultaneously, during this process, the reciprocating screw rotating shaft on the reciprocating screw mechanism 10 drives the first gear 93 to rotate. Through gear meshing, the second gear 94 and the flexible cleaning brush 95 rotate. The brush bristles wipe the surface of the moving wire. The flexible cleaning brush 95 continues to rotate during winding, cleaning the wire recovered from the construction site and removing residual cement slurry, dust, and other impurities from the wire surface. This prevents impurities from embedding into the wire fibers or adhering to the surface, thus avoiding wear and tear on the wire during the winding process and extending the service life of the wire.

[0027] After the wire is completely wound onto the spool, turn off the drive motor 3, rotate the rotating pressure block 5 counterclockwise, and remove the spool from the placement shaft of the winding drum 4 to complete the entire operation. If it is to be used again later, the spool can be reinstalled and the above operation can be repeated without additional cleaning steps, thus improving construction efficiency.
