[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 It can be seen that a water conservancy construction line-laying device includes a fixed plate 1, a support leg 2 is provided below the fixed plate 1, a line-laying box 3 is provided above the fixed plate 1, a spool 4 and a lead screw 5 are arranged in parallel in the line-laying box 3, the spool 4 is driven by a motor 6, and a first gear 7 connected via a first clutch and a second gear 8 connected via a second clutch are respectively arranged at both ends of the spool 4, a third gear 9 and a fourth gear 10 are respectively arranged at both ends of the lead screw 5, the third gear 9 is meshed with the first gear 7 via a fifth gear 11, and the fourth gear 10 is meshed with the second gear 8, a wire rack 12 is arranged on the lead screw 5, the wire rack 12 is threadedly connected to the lead screw 5, and a line-laying hole 13 is provided at the front end of the line-laying box 3.
[0016] When the utility model is used in a specific way,
[0017] The wire rope is wound around the bobbin 4, passes through the wire frame 12 and then extends out of the wire-paying box 3 from the wire-paying hole 13. When paying out the wire, the motor 6 drives the bobbin 4 to rotate, the wire rope is loosened, and is discharged from the wire-paying hole 13 for the wire-paying operation. While paying out the wire, the wire frame 12 moves laterally to match the position of the wire rope on the bobbin 4 to avoid the smooth progress of the wire-paying by knotting or deflection. Similarly, when collecting the wire, the wire rope is wound around the bobbin 4 after passing through the wire frame 12, so that the wire rope is even and has appropriate tightness, which is convenient for subsequent wire-paying.
[0018] During the process of paying out the line, only one of the first clutch and the second clutch is in working state, that is, the first gear 7 or the second gear 8 rotates synchronously with the spool 4, thereby realizing the transmission of the lead screw 5. When the first gear 7 rotates synchronously with the spool 4, the lead screw 5 and the spool 4 rotate in the same direction, and the wire frame 12 moves toward the first gear 7. When the second gear 8 rotates synchronously with the spool 4, the lead screw 5 and the spool 4 rotate in opposite directions, and the wire frame 12 moves toward the second gear 8. The switching between the first clutch and the second clutch is carried out when the wire frame 12 moves to the end of the lead screw 5, thereby realizing the reciprocating movement of the wire frame 12 on the lead screw 5.
[0019] The supporting leg 2 is a retractable tripod that can be adjusted according to the conditions at the construction site.
[0020] The transmission ratio of the first gear 7 to the third gear 9 is 1:1, and the transmission ratio of the second gear 8 to the fourth gear 10 is 1:1, so that the rotation speed of the screw 5 is the same as that of the spool 4, and the moving speed of the wire rack 12 matches the rotation speed of the spool 4, making the winding density of the rope more reasonable.
[0021] The wire rack 12 includes a sleeve shaft 14 threadedly connected to the lead screw 5, a guide rod 15 is provided above the sleeve shaft 14, a wire plate 16 is provided on the side of the sleeve shaft 14 facing the wire release hole 13, a wire hole 17 is opened on the wire plate 16, a limiting rod 18 extends from the bottom of the sleeve shaft 14, and a limiting groove 19 is provided at the bottom of the wire release box 3, and the limiting rod 18 slides in the limiting groove 19.
[0022] The wire rope passes between the guide rod 15 and the sleeve shaft 14 , and then extends out of the wire release box 3 from the wire release hole 13 through the wire hole 17 . The cooperation between the limit rod 18 and the limit groove 19 enables the wire rack 12 to move horizontally on the lead screw 5 .
[0023] A first touch switch 20 is provided under the third gear 9, a second touch switch 21 is provided under the fourth gear 10, touch rods 22 extend from both sides of the limit rod 18, and the first touch switch 20 and the second touch switch 21 are electrically connected to the first clutch and the second clutch.
[0024] When the wire rack 12 moves on the screw 5 so that the contact rod 22 contacts the first touch switch 20, the first clutch is closed and the second clutch is disconnected, so that the first gear 7 rotates synchronously with the spool 4, the screw 5 and the spool 4 rotate in the same direction, and the wire rack 12 switches the moving direction. Similarly, when the contact rod 22 contacts the second touch switch 21, the first clutch is disconnected and the second clutch is closed, so that the second gear 8 rotates synchronously with the spool 4, the screw 5 and the spool 4 rotate in the opposite direction, and the wire rack 12 switches the moving direction, so that the winding direction of the rope on the spool 4 is continuously switched.
[0025] Compared with the prior art, the utility model has the following beneficial effects: a wire rack is arranged on the side of the spool to guide the wire rope, so that the wire rope is evenly wound on the spool, avoiding undesirable conditions such as uneven wire release speed or wire jamming caused by uneven wire rope, and ensuring smooth wire release.
