Description

Technical Field

[0001] This utility model relates to the field of sling processing technology, and more specifically to a quantitative winding device for elastic slings. Background Technology

[0002] Flexible slings are suspension devices for the overhead contact system of electrified railway traction power supply systems. They are made of Φ35mm magnesium-copper alloy stranded wire, and the spools provided by manufacturers are typically 80cm in diameter, 3000 meters long, and weigh about one ton. Before installation, flexible slings need to be cut to the required length and wound into multiple small rolls before being transported to the installation site. Current methods for cutting flexible slings usually involve multiple workers straightening the wire on the spool, measuring the required length, cutting it, and then winding it into small rolls using a winding reel. This typically requires 6-7 workers, wasting significant manpower, resulting in low efficiency and measurement accuracy. Some existing devices use length sensors to measure the sling length, which improves accuracy, but is more expensive, and the sensors are greatly affected by environmental factors; damage to these sensors can easily prevent further measurements.

[0003] Therefore, how to provide a flexible sling quantitative winding device that saves manpower, is highly efficient, and has high measurement accuracy is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention aims to provide a quantitative winding device for elastic slings to at least partially solve the problems of manual winding being time-consuming, labor-intensive, and inaccurate, and the high accuracy of sensor measurement being greatly affected by environmental factors, and the inability to continue measurement once damaged.

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

[0006] A quantitative winding device for elastic slings includes: a quantitative tube for threading the sling, an unwinding mechanism, a winding mechanism, a marking mechanism, a first marking identification mechanism, a counter, and a wire-cutting mechanism; the unwinding mechanism and the winding mechanism are respectively located at a first end and a second end of the quantitative tube; the marking mechanism is installed at the end of the first end of the quantitative tube to mark the surface of the sling; the first marking identification mechanism is installed at the end of the second end of the quantitative tube; the counter is used to count the number of marks on the sling surface; and the wire-cutting mechanism is installed between the first marking identification mechanism and the winding mechanism.

[0007] The beneficial effects achievable by this invention are as follows: the head of the elastic sling on the unwinding mechanism passes from the first end to the second end of the quantitative tube. When the first marking and identification mechanism detects that the head of the elastic sling has passed through the second end of the quantitative tube, the controller controls the marking mechanism to make a first mark on the surface of the elastic sling corresponding to the first end of the quantitative tube. Then, the elastic sling continues to be fed to the second end of the quantitative tube, and the head of the elastic sling begins to wind on the winding mechanism until the first marking and identification mechanism detects the first mark. At this point, the marking mechanism makes a second mark on the surface of the elastic sling corresponding to the first end of the quantitative tube, and the counter starts counting. Since the length of the quantitative tube is known, the total length of the elastic sling that has passed through the second end of the quantitative tube can be determined based on the count value of the counter. When the total length of the elastic sling reaches the set value, it is cut at the corresponding mark by the wire-cutting mechanism, thus completing the quantitative winding of the elastic sling.

[0008] Furthermore, it also includes multiple quantitative tube support frames, which are arranged at intervals along the axial direction of the quantitative tube and supported at the bottom of the quantitative tube.

[0009] Furthermore, the unwinding mechanism includes an unwinding lifting frame and an unwinding shaft. The unwinding lifting frame is installed at the first end of the quantitative tube, and the unwinding shaft is rotatably installed at the lifting end of the unwinding lifting frame.

[0010] Furthermore, the winding mechanism includes a winding lifting frame, a winding motor, and a winding wheel. The winding lifting frame is installed on the side of the wire cutting mechanism away from the quantitative tube. The winding motor is fixed to the lifting end of the winding lifting frame. The winding wheel is rotatably connected to the lifting end of the winding lifting frame and is drivenly connected to the output end of the winding motor.

[0011] Furthermore, the marking mechanism includes an ink supply system and an inkjet head, with the inlet end of the inkjet head connected to the ink supply system and the outlet end arranged corresponding to the end of the first end of the metering tube.

[0012] Furthermore, a second mark recognition mechanism is provided, which is arranged corresponding to the wire cutting mechanism to recognize the marks on the surface of the sling. The controller is electrically connected to the second mark recognition mechanism to receive its recognition signal and control the wire cutting mechanism to perform cutting.

[0013] Furthermore, the first marker recognition mechanism and / or the second marker recognition mechanism is an image acquisition camera or a color sensor.

[0014] Furthermore, the wire-cutting mechanism is a hydraulically controlled or electrically controlled scissor.

[0015] Furthermore, it also includes wire clamps for preventing the sling from slipping off both sides when cut, wherein two clamps are provided and the two clamps are respectively installed on both sides of the wire cutting mechanism.

[0016] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a quantitative winding device for elastic slings, which has the following beneficial effects:

[0017] 1. By utilizing the synergistic effect of the quantitative tube, marking mechanism, first mark recognition mechanism and counter, the length of the sling wound by the winding mechanism can be accurately measured, reducing the difficulty of manual measurement, improving the accuracy of measurement, and avoiding material waste caused by insufficient or excessive sling length; moreover, it eliminates the need for high-cost length sensors and avoids situations where sensors are damaged and measurement is impossible.

[0018] 2. Wire clamps are installed on both sides of the wire cutting mechanism to prevent the sling from coming loose at the cut point, which would affect subsequent measurement and winding work. Attached Figure Description

[0025] Please see Figure 1 This utility model discloses a quantitative winding device for elastic slings, comprising a quantitative tube 1 for threading the sling, an unwinding mechanism 2, a winding mechanism 3, a marking mechanism 4, a first marking identification mechanism 5, a counter 6, and a wire-cutting mechanism 7. The unwinding mechanism 2 and the winding mechanism 3 are respectively installed at the first end and the second end of the quantitative tube 1. The marking mechanism 4 is installed at the end of the first end of the quantitative tube 1 to mark the surface of the sling. The first marking identification mechanism 5 is installed at the end of the second end of the quantitative tube 1 to identify the markings made by the marking mechanism 4 on the surface of the elastic sling 9. The controller receives the identification signal from the first marking identification mechanism 5 to control the marking mechanism 4 to mark and control the counter 6 to count. The wire-cutting mechanism 7 is installed between the first marking identification mechanism and the winding mechanism 3.

[0026] Specifically, it also includes multiple quantitative tube support frames 8, which are arranged at intervals along the axial direction of the quantitative tube 1 and supported at the bottom of the quantitative tube 1 to support the elastic sling 9 and prevent it from dragging and wearing on the ground.

[0027] Specifically, the unwinding mechanism 2 includes an unwinding lifting frame 21 and an unwinding shaft 22. The unwinding lifting frame 21 is installed at the first end of the quantitative tube 1, and the unwinding shaft 22 is rotatably installed at the lifting end of the unwinding lifting frame 21. The coil is installed on the unwinding shaft 22, and the unwinding lifting frame 21 can adjust the height of the coil so that the elastic sling 9 can pass horizontally through the quantitative tube 1, facilitating smooth transport within the quantitative tube 1.

[0028] Specifically, the winding mechanism 3 includes a winding lifting frame 31, a winding motor 32, and a winding reel 33. The winding lifting frame 31 is installed on the side of the wire cutting mechanism 7 away from the metering tube 1. The winding motor 32 is fixed to the lifting end of the winding lifting frame 31. The winding reel 33 is rotatably connected to the lifting end of the winding lifting frame 31 and is driven by the output end of the winding motor 32. The height of the winding reel 33 is adjusted so that the sling is horizontal after passing through the metering tube 1, avoiding friction with the metering tube 1, so that it can be smoothly wound on the winding reel 33.

[0029] Specifically, the marking mechanism 4 includes an ink supply system and an inkjet head. The inlet end of the inkjet head is connected to the ink supply system, and the outlet end is arranged at the end corresponding to the first end of the metering tube 1. The inkjet head sprays fine lines of paint onto the cable surface as markings, so that the length of the wound cable can be determined later based on the number of markings. In some other embodiments, the marking mechanism 4 can also be a marker pen.

[0030] Specifically, a second mark recognition mechanism is also provided, which is arranged in accordance with the wire cutting mechanism 7 to recognize the marks on the surface of the sling.

[0035] Example 1: This example provides a semi-automatic winding method, taking a 9-meter-long quantitative tube 1 as an example to achieve quantitative winding of an 18-meter-long elastic sling 9:

[0036] Workers 1 and 2 are positioned at opposite ends of the metering tube. Worker 1 pulls the free end of the elastic sling 9 on the unwinding mechanism 2, allowing it to pass through the first end of the metering tube 1 and continuously feed the wire forward. When Worker 2 observes that the free end of the elastic sling 9 reaches the second end of the metering tube 1, Worker 1 draws a first marking line on the surface of the elastic sling 9 corresponding to the end of the metering tube 1 using a marker. Then, the elastic sling 9 continues to be fed. Worker 2 fixes the head of the elastic sling 9 to the take-up reel and starts the take-up motor 32 to perform the take-up operation, continuously observing the feeding of the elastic sling 9 at the second end of the metering tube 1. When Worker 2 observes that the first marking line reaches the second end of the metering tube 1, Worker 1 draws a second marking line on the surface of the elastic sling 9 corresponding to the first end of the metering tube 1. When Worker 2 observes that the second marking line emerges from the second end of the metering tube 1, Worker 1 draws a third marking line on the surface of the elastic sling 9 corresponding to the first end of the metering tube 1. Since the elastic sling 9 corresponding to the second marking line is the length of two quantitative tubes 1, reaching the required 18-meter length, the feeding and winding of the wire is paused when worker number 2 observes the second marking line being fed to the wire cutting mechanism 7. Worker number 2 secures the slings on both sides of the second marking line to the anchoring devices on both sides of the wire cutting mechanism 7 with steel wire to prevent the slings from loosening after cutting. Then, the elastic sling 9 is cut at the second marking line using the wire cutting mechanism 7. The elastic sling 9 on the winding reel is then secured with cable ties. The corresponding steel wire is untied, and the tied elastic sling is removed and placed in the storage area, completing the winding operation of the first roll of elastic sling 9. Subsequently, the other steel wire is untied, and the remaining elastic sling 9 is wound onto the winding reel. When the third marking line reaches the second end of the quantitative tube 1, the fourth marking line is drawn as above, and the above steps are repeated to complete the quantitative winding operation of the elastic sling 9. It can be seen that this embodiment only requires two workers to work together to complete the winding operation of the elastic sling 9, reducing manpower and improving work efficiency.

[0037] Example 2:

[0038] This embodiment provides a fully automated winding method, taking the quantitative winding operation of an 18-meter-long elastic sling 9 using a 9-meter-long quantitative tube 1 as an example:

[0039] The worker marks the head of the sling with paint and inserts the sling from the first end of the metering tube 1. When it emerges from the second end of the metering tube 1, the first marking recognition mechanism 5 detects the mark on the sling head. At this time, the controller controls the inkjet head to spray the first marking line onto the sling surface corresponding to the first end of the metering tube 1. The sling continues to be conveyed, and the worker winds the sling head onto the take-up reel 33 and starts the take-up mechanism to take it up. When the first marking line emerges from the second end of the metering tube 1, the first marking recognition mechanism 5 detects the marking signal and feeds it back to the controller. The controller controls the counter 6 to start counting, and the count is 1 at this time. At the same time, the controller controls the inkjet head to draw the second marking line. When the first marking recognition mechanism 5 detects the second marking line, the counter 6 counts to 2, and the inkjet head draws the third marking line. When the second marker recognition mechanism detects the second marker line, the controller controls the take-up motor 32 to pause winding and controls the wire clamps on both sides to clamp the slings on both sides of the second marker line. The wire cutting mechanism 7 is then activated to cut the slings. At this time, the counter 6 returns to zero (the distance between the second end of the quantitative tube 1 and the wire cutting mechanism 7 is less than the length of the quantitative tube 1, i.e., less than 9 meters). After cutting, the wire clamp near the take-up reel 33 is opened, and the worker securely ties the slings on the take-up reel 33 before removing and storing them. Then, the controller controls the clamp near the quantitative tube 1 to open, and the worker re-fixes the cut cable end onto the take-up reel 33 to continue winding. When the first marker recognition mechanism 5 detects the third marker line, the counter 6 counts back to 1, and the inkjet head draws the fourth marker line. The above steps are repeated to complete the quantitative winding operation of the elastic sling 9. In summary, this embodiment requires only one worker to perform auxiliary work to complete the automated quantitative winding operation of the elastic sling 9.

[0040] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
