Movable rope winding machine

Abstract

The utility model relates to a movable rope winding machine. The movable rope winding rack comprises a rope winding disc, a frame, a rope feeding mechanism and a transmission mechanism; compared with the prior art, the device is simple in structure, light in weight, powered by a direct-current power supply and convenient to move. In the rope winding process, the motor drives the rope winding disc to rotate so that the steel wire rope can be wound around the peripheries of the four rope winding rods, the Hall element can measure the length of the steel wire rope in the rope winding process, and the length of the steel wire rope can be displayed on the displayer. The friction force between the friction disc and the shaft base plate is adjusted by adjusting the tightness of nuts at the heads of the two shaft screw rods, and when the friction force is exceeded due to the abnormal conditions such as rope clamping, the friction disc and the shaft base plate slip, and the friction disc and the shaft base plate are driven to rotate. Therefore, damage to structural parts of equipment and potential safety hazards to workers caused by accidental strong rotation of the wound rope during rope winding are avoided. And the worker can continuously and normally take up the rope after removing the fault.

[0002] Steel wire ropes are frequently used on construction sites, and after use, they must be wound up using a rope winding machine. However, traditional rope winding machines are complex in structure and mostly large machines. Workers need to manually wind the steel wire rope on-site, then carry it back to the factory for winding with a large rope winding machine, which is time-consuming and labor-intensive. Moreover, in case of abnormal situations such as rope jamming, the accidental and forceful rotation of the winding reel can damage the structural components of the equipment and create safety hazards for workers. This invention develops a mobile rope winding machine that uses a friction disc to drive the winding reel, allowing for direct rope winding on-site, saving manpower, improving work efficiency, and avoiding the safety hazards of accidental and forceful rotation of the winding reel.

Detailed Implementation

[0012] The present invention will be further described below with reference to specific accompanying drawings and embodiments.

[0013] As shown in Figure 1, the present invention mainly consists of a rope winding reel 10, a frame 20, a rope feeding mechanism 30, and a transmission mechanism 40. The rope winding reel 10 includes an outer disc 11, outer disc holes 12, a rope winding rod 13, an inner cylinder 14, pin holes 15, bearing holes 16, and mounting holes 17 (see Figure 1). The two outer discs 11 are thin circular discs, and each outer disc 11 has four outer disc holes 12 and four pin holes 15 evenly arranged on its edge. The inner cylinder 14 is a cylindrical cylinder, and the inner cylinder 14 is welded to the left side of the outer disc 11. The inner cylinder 14 is the same as the outer disc 11. The left end of the winding rod 13 is fixed in the pin hole 15 of the left outer disk 11, and the right end of the winding rod 13 passes through the pin hole 15 of the right outer disk 11. Two mounting holes 17 are provided on the left outer disk 11. The frame 20 includes a base plate 21, wheels 22, pillars 23, a top box 24, a motor 25, threaded pipes 26, an electrical box 27, a display 28, and a Hall element 29 (see Figure 2). The base plate 21 is a welded T-shaped structure of two steel pipes, and the two wheels 22 are mounted on the base plate 21 via bearings. At the rear, a wheel 22 is mounted on the front of the base plate 21 via a bearing. The column 23 is bolted to the upper middle part of the base plate 21. The top box 24 is welded to the top of the column 23. The housing of the motor 25 is fixed to the top box 24. The threaded pipe 26 is fixed to the front middle position of the base plate 21. The electrical box 27 is fixed to the base plate 21. The display 28 is mounted on the electrical box 27 (see Figures 2 and 6). The Hall element 29 is fixed to the root of the threaded pipe 26. Component 29 is connected to the electrical box 27 via a wire. The electrical box 27 is equipped with a DC power supply to power the motor 25. The rope feeding mechanism 30 includes a chassis 31, a chassis shaft 32, a rope winding frame 33, and a wire rope 34 (see Figure 3). The chassis 31 is a circular disc. The chassis shaft 32 is mounted at the center of the chassis 31 via a bearing. The four rope winding frames 33 are right-angled steel rods. The lower parts of the four rope winding frames 33 are evenly welded to the middle of the chassis 31, and the upper parts of the four rope winding frames 33 are fixed to the bearing sleeve of the chassis shaft 32.The transmission mechanism 40 includes a transmission shaft 41, a shaft boss 42, a shaft base 43, shaft screws 44, a friction disc 45, a bearing 46, a shaft cover 47, a shaft cover hole 48, and a shaft hole 49 (see Figure 4). The transmission shaft 41 has the shaft boss 42 in the middle. The shaft base 43 has two shaft screws 44 at its upper and lower ends. The shaft base 43, the friction disc 45, the bearing 46, and the shaft cover 47 all have shaft holes 49 in the middle. The shaft cover 47 has two shaft cover holes 48 at its upper and lower ends. The left end of the transmission shaft 41 passes through the shaft hole 49 on the shaft base 43. Then, the two shaft screws 44 pass through the mounting holes 17 of the two left outer disks 11 respectively (see Figure 1). The right end of the transmission shaft 41 then passes through the outer disks. The bearing hole 16 of drive shaft 11 is engaged with the shaft boss 42. The friction disc 45, the bearing 46, and the shaft cover disc 47 are inserted into the right end of the drive shaft 41 through the shaft hole 49. The friction disc 45 is connected to the drive shaft 41 via a shaft key. Then, two shaft screws 44 are inserted into the two shaft cover holes 48 respectively, and nuts are screwed onto the heads of the two shaft screws 44 (see Figure 5). The drive shaft 41 is then mounted on the bearing hole 16 of the outer disc 11 on the right end via a bearing, thereby connecting and fixing the outer disc 11 on the right end and the outer disc 11 on the left end into a whole (see Figure 6). The left end of the drive shaft 41 is fixed to the shaft of the motor 25, thereby connecting the rope winding disc 10 and the motor 25 (see Figures 2 and 6).

[0014] In practical application (see Figure 6), the worker places the initially coiled wire rope 34 around the four winding frames 33, then passes the end of the wire rope 34 through the threaded tube 26 and clamps it between the winding rod 13 and the inner cylinder 14 (see Figure 5). Then, the motor 25 is started to drive the drive shaft 41 to rotate. Since the friction disc 45 is connected to the drive shaft 41 through a key, the friction disc 45 rotates synchronously with the drive shaft 41. The right side of the friction disc 45 is connected to the shaft cover disc 47 through the bearing 46, so the shaft cover disc 47 does not rotate synchronously with the friction disc 45. The left side of the friction disc 45 is in direct contact with the shaft base disc 43, and the friction force drives the shaft base disc 43 to rotate, thereby driving the shaft cover disc 47 to rotate synchronously, and driving the two outer discs 11 on the left and right to rotate synchronously, and finally driving the winding disc 10 to rotate synchronously. The rotation of the winding disc 10 causes the wire rope 34 to be wound around the four winding rods 13 (see Figure 1). During the rope winding process, the Hall element 29 measures the length of the wire rope 34 and displays it on the display 28. The tension of the nuts on the heads of the two shaft screws 44 is adjusted during winding to regulate the friction between the friction disc 45 and the shaft base 43. Under normal operation, this friction is sufficient to rotate the winding disc 10. If a jamming or other abnormal situation occurs and exceeds this friction, slippage occurs between the friction disc 45 and the shaft base 43. The operator resolves the fault and then continues winding normally. After winding is complete, the operator disconnects the drive shaft 41 from the bearing hole 16 of the outer disc 11, removes the right end of the outer disc 11, and then takes out the wound wire rope 34, completing the entire winding process.

[0015] Compared with the prior art, the advantages of this invention are: the mobile rope winding machine has a simple structure, is lightweight, uses DC power supply, and is easy to move. During the rope winding process, the motor 25 drives the winding reel 10 to rotate, causing the wire rope 34 to wind around the four winding rods 13. During the winding process, the Hall element 29 can measure the length of the wire rope and display it on the display 28. During the winding process, the tension of the nuts on the heads of the two shaft screws 44 is adjusted to regulate the friction force between the friction disc 45 and the shaft base plate 43. When an abnormal situation such as rope jamming occurs and exceeds the friction force, the friction disc 45 slips between the shaft base plate 43, thereby avoiding damage to the equipment structure components and safety hazards to workers caused by the accidental and forceful rotation of the winding reel 10 during rope winding. After the worker resolves the fault, the rope winding can continue normally. After the rope winding is completed, the worker can easily remove the outer disc of the winding reel and then take out the wound wire rope, completing the entire rope winding process.
