Description

Technical Field

[0001] The present invention relates to the technical field of wire pay-off machines, and in particular to a precise wire pay-off machine. Background Art

[0002] A pay-off machine is an auxiliary device for wires and cables that works with a stranding machine to pay off the wires. Pay-off machines can generally be categorized into several types: active back-twist pay-offs, vertical power pay-offs, dual-shaft power pay-offs, dual-shaft multi-head drawing disc active pay-offs, and shaftless pay-offs.

[0003] Existing pay-off machines struggle to maintain stable positioning on construction sites with complex terrain, such as uneven terrain, slopes, or soft soil. They are prone to shaking or even tipping over. This instability directly leads to tension fluctuations during the pay-off process, severely impacting pay-off accuracy and making it difficult to ensure the required wire position and tension.

[0004] When changing coils of different diameters on existing pay-off machines, operators often need to disassemble and replace the entire fixture or perform complex mechanical adjustments, which is very time-consuming and labor-intensive. This not only reduces work efficiency but also makes it difficult to meet practical needs when frequent changes in coil specifications are required. Therefore, a precise pay-off machine is needed. Summary of the Invention

[0005] In order to overcome the defects in the prior art, a precise pay-off machine is provided.

[0006] The present invention is achieved through the following solutions:

[0007] A precise wire-laying machine includes a fixed bracket and a supporting foot connected thereto. One side of the fixed bracket is connected to a circular support bracket. The fixed bracket is connected to a control room. Several rollers are evenly arranged around the support bracket. Several rollers are connected to a rotating disk. Several limiting grooves are provided in the rotating disk. Each limiting groove is connected to a limiter. Several claws are evenly arranged on the outside of the rotating disk. The rotating disk is electrically connected to the control room.

[0008] The fixing bracket includes a first bracket and a second bracket vertically added together, and a plurality of supporting legs are correspondingly provided around the periphery of the first bracket and the second bracket.

[0009] The supporting feet are correspondingly arranged below the supporting frame, and the supporting feet include fixed supporting feet and movable supporting feet. Several movable supporting feet are correspondingly arranged around the periphery of the first bracket, and several fixed supporting feet are correspondingly arranged around the periphery of the second bracket.

[0011] The length of the first bracket is smaller than the diameter of the bracket, the length of the second bracket is larger than the diameter of the bracket, and a control chamber is correspondingly provided at one end of the second bracket.

[0012] The rotating disk is correspondingly connected to the fixed bracket through a rotating shaft.

[0013] The rotating shaft is electrically connected to the control chamber, and a running motor is correspondingly provided above the control chamber.

[0014] The limiter can slide correspondingly in the limiting groove. The limiter includes a slider and a fixer. The slider is correspondingly connected to the limiting groove, and the fixer is correspondingly connected to the slider.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention provides a precise pay-off machine with various types of support legs. The height of the movable support legs is adjusted by a lifting screw, so that the support legs can be applied to various complex terrains.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1 and Figure 2As shown, a precise wire-laying machine includes a fixed bracket 3 and a supporting foot 2 connected thereto. One side of the fixed bracket 3 is connected to a ring-shaped support frame 1. The fixed bracket 3 is connected to a control room 4. Several rollers 5 are evenly arranged around the support frame 1. Several rollers 5 are connected to a rotating disk 6. Several limit slots 8 are provided in the rotating disk 6. Each limit slot 8 is connected to a limiter 9. Several claws 10 are evenly arranged on the outside of the rotating disk 6. The rotating disk 6 is electrically connected to the control room 4. The control room 4 of the present invention adopts a PLC or microcomputer control system to support preset parameters such as wire-laying length, speed, and tension. The control room 4 of the present invention is also provided with a tension control system. The tension control system is connected to the control room 4. The tension control system includes brakes, sensors, etc., which play a role in maintaining constant tension. The present invention adjusts the wire-laying tension in real time through the tension control system to prevent the steel strand from being too tight or loose. The present invention can release steel strands efficiently and accurately, and has functions such as intelligent control, tension adjustment, and automatic measurement, which can greatly improve construction efficiency and reduce manual errors.

[0023] The fixed bracket 3 includes a first bracket 31 and a second bracket 32 vertically added together, and a plurality of supporting feet 2 are provided on the periphery of the first bracket 31 and the second bracket 32. The supporting feet 2 are correspondingly arranged below the support frame 1, and the supporting feet 2 include fixed supporting feet 21 and movable supporting feet 22. A plurality of movable supporting feet 22 are provided on the periphery of the first bracket 31, and a plurality of fixed supporting feet 21 are provided on the periphery of the second bracket 32. The movable supporting feet 22 include a positioning frame 221 and a lifting screw 222, and the lifting screw 222 can move correspondingly within the positioning frame 221. The present invention is provided with 4 fixed supporting feet 21 and 4 movable supporting feet 22, and the lifting screw 222 can move up and down inside the positioning frame 221, so the staff can independently adjust the length of the lifting screw 222 of each movable supporting foot 22 extending out of the positioning frame 221 according to the actual undulations of the ground. Through this multi-point independent adjustment method, the present invention can always keep the support frame 1 horizontal and stable even if the ground is uneven, thereby improving the adaptability and overall stability of the present invention on complex terrain and laying a solid foundation for subsequent precise line laying.

[0024] The length of the first bracket 31 is shorter than the diameter of the support frame 1, while the length of the second bracket 32 is longer than the diameter of the support frame 1. A control chamber 4 is located at one end of the second bracket 32. The rotating disk 6 is connected to the fixed bracket 3 via a rotating shaft 7. The rotating shaft 7 is electrically connected to the control chamber 4, and an operating motor 11 is located above the control chamber 4. By providing first and second brackets 31, 32 of different lengths, the present invention achieves a compact structure, reduces floor space, and improves practicality.

[0025] The limiter 9 can slide in the limit slot 8. The limiter 9 includes a slider 91 and a fixer 92. The slider 91 is connected to the limit slot 8, and the fixer 92 is connected to the slider 91. The present invention has four limit slots 8 in the rotating disk 6, and six claws 10 are evenly arranged on the outside of the rotating disk 6. When the steel strand coil is placed in the rotating disk 6, the limiter 9 slides along the limit slot 8. Each limiter 9 clamps the inside of the steel strand coil respectively. The fixer 92 is tightened and fixed. At the same time, the claws 10 on the outside of the rotating disk 6 wrap the steel strand coil to achieve the purpose of fixing the steel strand coil. The limiter 9 of the present invention can be adjusted in the limit slot 8 to support steel strand coils with different inner diameters. At the same time, another function of the claws is that during the pay-off process, since the part of the pay-off will open, the claws are in a slightly open state to avoid affecting the pay-off of the steel strand.

[0026] In a specific embodiment, the height is adjusted by the lifting screw 222 to ensure that the present invention always maintains horizontal stability. The steel strand coil is placed in the rotating disk 6, the limiter 9 clamps the inside of the steel strand coil, and the claw 10 wraps the outside of the steel strand coil. After the control room 4 is powered on, the control motor 11 is controlled to drive the rotating disk 6 to operate. The steel strand coil can be continuously unwound through the action of the winding machine traction rope. The control room 4 system displays the unwound length and tension status in real time. After reaching the set length, the machine is stopped remotely or manually, and the matching cutting equipment is used to cut the steel strand.

[0027] The present invention can be applied to scenarios such as prestressed concrete bridge construction, steel strand tensioning of large building structures, prestressed flexible photovoltaic cable laying, high-voltage transmission line installation, and cable-stayed bridge maintenance.

[0028] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
