[0004] 1. Multiple people pull the cable at the same time to rotate the H-shaped drum, so that the cable wrapped outside is pulled out. When the cable is released, the H-shaped drum is placed vertically and is prone to fall due to frequent pulling of external force when rotating, which may damage the cable or cause harm to the surrounding staff.
[0005] 2. The H-shaped drum will also generate inertia when rotating, which will lead to excessive line release, causing the excess line in the line release device to be spit out. It is necessary to manually rewind the line onto the H-shaped drum, wasting a lot of time for construction workers and making it more troublesome to use. Therefore, a construction line release device is needed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a construction laying-out device, comprising a moving plate 1, a push rod 101 is fixedly connected to the top of the moving plate 1, a plurality of brake universal wheels 102 are fixedly installed at the bottom of the moving plate 1, a laying-out mechanism is arranged at the top of the moving plate 1, and the laying-out mechanism comprises a base 2, the base 2 is fixedly connected to the top of the moving plate 1, a rotating drum 201 is rotatably arranged at the top of the base 2, a top plate 202 is fixedly connected to the top of the rotating drum 201, a hand wheel 203 is fixedly connected to the top of the top plate 202, a cable body 3 is rolled up at the outer end of the rotating drum 201, a plurality of ground nails 103 are installed at the top of the moving plate 1, and the moving plate 1 is pushed to the construction site of the power construction by pushing the push rod 101. At this time, each ground nail 103 is passed through the top of the movable plate 1 and fixed to the ground. After the brake universal wheel 102 steps on the brake plate respectively, the movable plate 1 and the wire-releasing mechanism can be fixed to the ground as a whole. The setting of the ground nail 103 improves the stability of the brake universal wheel 102 and the movable plate 1 fixed on the ground, thereby preventing the wire-releasing mechanism and the movable plate 1 from tipping over due to frequent pulling of the cable by external force, thereby causing damage to the cable or causing harm to the surrounding personnel. A wire transmission component 1 is provided at the top of the movable plate 1, and an installation groove 104 is opened at the top of the movable plate 1. A rebound mechanism is provided inside the installation groove 104, a wire transmission component 2 is provided at the top of the rebound mechanism, and a limiting mechanism is provided at the top of the rebound mechanism.
[0024] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the wire transmission component 1 includes a motor 4, which is fixedly mounted on the bottom end of the moving plate 1, and a rotating rod 401 is fixedly mounted on the output end of the motor 4, and the rotating rod 401 is inserted into the top end of the moving plate 1, and a roller 402 is fixedly connected to the top end of the rotating rod 401;
[0025] The rebound mechanism includes a round rod 5, which is fixedly connected between the inner side ends of the installation groove 104, a spring 1 501 is sleeved on the outer end of the round rod 5, a rectangular sleeve 502 is sleeved on the outer end of the round rod 5, a side plate 503 is fixedly connected to the side end of the rectangular sleeve 502, a wire transmission component 2 is located at the top end of the rectangular sleeve 502, and a limit mechanism is located at the top end of the side plate 503;
[0026] The second wire transmission component includes a second rotating rod 504, which is fixedly connected to the top of the rectangular sleeve 502. The top of the second rotating rod 504 is rotatably provided with a second roller 505. During implementation, by pressing the limit mechanism downward and then pulling the second rotating rod 504, the rectangular sleeve 502 is pressed against the spring 1 501 to shrink. At this time, the head end of the cable body 3 is placed between the roller 1 402 and the second roller 505. Then, after the second rotating rod 504 is released, the spring 1 501 will push against the rectangular sleeve 502 to drive the second roller 505 to rebound. The second roller 505 and the first roller 402 will clamp the cable body 3. Due to the coordinated arrangement of the rebound mechanism and the limit mechanism, the first roller 402 and the second roller 505 can clamp and fix the cable body 3 of different thicknesses.
[0027] When the cable body 3 is located between roller 1 402 and roller 2 505, the motor 4 is started to drive the rotating rod 1 401 and roller 1 402 to rotate. At this time, after cooperating with roller 2 505, the cable body 3 can be unwound by turning the hand wheel 203. The coordinated use of the motor 4, the rotating rod 1 401, the roller 1 402 and the roller 2 505 can increase the unwinding speed of the cable body 3. At the same time, when the unwinding is completed, the motor 4 can be turned off at any time. At this time, after roller 1 402 stops rotating, the clamping force of roller 1 402 and roller 2 505 on the cable body 3 can avoid excessive unwinding of the redundant cable body 3, thereby avoiding the need to manually rewind the wire onto the H-shaped drum, wasting a lot of time of construction personnel and being more troublesome to use.
[0028] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the limiting mechanism includes a hollow rod 6, which is fixedly connected to the top of the side plate 503, and the inner bottom end of the hollow rod 6 is fixedly connected to a spring 2 601, and the top of the spring 2 601 is fixedly connected to a limiting plate 602, and the top of the limiting plate 602 is fixedly connected to a limiting rod 603, and the side end of the limiting rod 603 is fixedly connected to a pull plate 604, and the top of the movable plate 1 is fixedly connected to a side frame 7, and the top of the side frame 7 is provided with a plurality of round holes 701. In the implementation, the head end of the cable body 3 is placed on the roller 14 02 and roller 2 505, and then one hand releases the rotating rod 2 504, and the other hand keeps pressing the pull plate 604, at this time, the spring 1 501 will push against the rectangular sleeve 502 to drive the roller 2 505 to rebound, and the roller 2 505 and roller 1 402 will clamp the cable body 3. At this time, after releasing the pull plate 604, the spring 2 601 pushes against the limit plate 602 to drive the limit rod 603 to rebound, and the limit rod 603 is reinserted into the round hole 701, so as to facilitate fixing the position of the roller 2 505.
[0029] Working principle: During the implementation of the wire-laying device for power construction, the push rod 101 is pushed to push the mobile plate 1 to the construction site of the power construction. At this time, each ground nail 103 is passed through the top of the mobile plate 1 and fixed to the ground. After the brake universal wheel 102 steps on the brake plate respectively, the mobile plate 1 and the wire-laying mechanism can be fixed to the ground as a whole. The setting of the ground nail 103 improves the stability of the brake universal wheel 102 and the mobile plate 1 fixed to the ground, thereby preventing the wire-laying mechanism and the mobile plate 1 from tipping over due to frequent pulling of the cable by external force, thereby causing damage to the cable or causing harm to the surrounding workers;
[0030] Then, by turning the hand wheel 203, the drum 201 is rotated. At the same time, by pulling the pull plate 604 downward, the pull plate 604 drives the limit rod 603 to move toward the inside of the hollow rod 6, and the spring 2 601 is squeezed by the limit plate 602 and contracts. At this time, the limit rod 603 leaves the circular hole 701. At this time, by pulling the rotating rod 2 504, the rectangular sleeve 502 presses the spring 1 501 to contract. At this time, the head end of the cable body 3 is placed on the roller 1 4 02 and roller 2 505, then one hand releases the rotating rod 2 504, and the other hand keeps pressing the pull plate 604, at this time, the spring 1 501 will push against the rectangular sleeve 502 to drive the roller 2 505 to rebound, and the roller 2 505 and roller 1 402 will clamp the cable body 3, at this time, after releasing the pull plate 604, the spring 2 601 pushes against the limit plate 602 to drive the limit rod 603 to rebound, and the limit rod 603 is re-inserted into the round hole 701, thereby pressing the roller 2 505. 05 is fixed in position. Due to the coordinated arrangement of the rebound mechanism and the limit mechanism, the roller 1 402 and the roller 2 505 can clamp and fix the cable body 3 of different thicknesses. When the cable body 3 is located between the roller 1 402 and the roller 2 505, the motor 4 is started to drive the rotating rod 1 401 and the roller 1 402 to rotate. At this time, after cooperating with the roller 2 505, the cable body 3 can be unwound by turning the hand wheel 203. The coordinated use of the motor 4, the rotating rod 1 401, the roller 1 402 and the roller 2 505 can increase the unwinding speed of the cable body 3. At the same time, when the unwinding is completed, the motor 4 can be turned off at any time. At this time, after the roller 1 402 stops rotating, the clamping force of the roller 1 402 and the roller 2 505 on the cable body 3 can avoid excessive unwinding of the redundant cable body 3, thereby avoiding the need to manually rewind the wire onto the H-shaped drum, wasting a lot of time for construction personnel and making it more troublesome to use.
[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
