Description

Technical Field

[0001] The utility model relates to the technical field of reels, in particular to a reel group with a speed limiting function. Background Art

[0002] Cables and wire ropes of different lengths are required for the installation of gantry cranes and large equipment. In order to deliver the cables and wire ropes to the exact length, the cables need to be cut and then reeled after cutting. Each section of cable and wire rope is 100 meters long and 1.2 meters wide. Therefore, a reel with a speed limit function is required to reel it.

[0003] The existing technology has the following problems:

[0004] In the prior art, when the cable is wound onto the small reel, when the small reel stops rotating, the large reel cannot stop in time, causing the cable wound on the small reel to become loose. At the same time, when the cable is wound onto the small reel, during the winding process, the large reel is rotated by the cable tension, resulting in unstable rotation speed of the large reel. When the large reel rotates too fast due to inertia, the cable wound on the small reel will scatter, reducing the practicality of the device. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 5 As shown, a reel group with a speed limiting function includes a base plate 1, a support plate 11 is fixedly connected to the front and rear of the top of the base plate 1, a mounting plate 12 is fixedly connected to the rear of the top of the base plate 1, the top of the mounting plate 12 is rotatably connected to a rotating shaft 13, the outer wall of the rotating shaft 13 is fixedly connected to a reel 14, the top of the right end of the support plate 11 is fixedly connected to a winding mechanism 2, the front of the base plate 1 is rotatably connected to a quick release mechanism 3, the top of the mounting plate 12 is fixedly connected to a speed limiting mechanism 4, the winding mechanism 2 includes a motor 21, the left end of the motor 21 is fixedly connected to the top of the right end of the support plate 11, the quick release mechanism 3 includes a threaded rod 31, the outer wall of the threaded rod 31 is rotatably connected to the front of the base plate 1, and the speed limiting mechanism 4 includes two fixed frames 41, and the outer wall of the fixed frame 41 is fixedly connected to the top of the mounting plate 12.

[0024] The cable is reeled in by the reeling mechanism 2, thereby driving the rotating shaft 13 and the reel 14 to rotate. During the rotation, the speed limiting mechanism 4 limits the speed of the rotating shaft 13. When the reeling is completed, the speed limiting mechanism 4 brakes the rotating shaft 13, and then the reeled cable can be removed through the quick release mechanism 3.

[0025] like Figure 2-Figure 4 As shown, the output end of the motor 21 is fixedly connected to the rotating rod 22, the outer wall of the rotating rod 22 is rotatably connected to the top of the support plate 11, the outer wall of the rotating rod 22 is slidably connected to the small reel 23 in a linear array, the outer wall of the rotating rod 22 is slidably connected to the stop block 24 in a linear array, one end of the small reel 23 overlaps with one end of the stop block 24, the left end of the rotating rod 22 is rotatably connected to the limiting block 26, the inner walls of the small reel 23 and the stop block 24 are fixedly connected to the limiting strip 25, and the outer wall of the limiting strip 25 is slidably connected to the inner wall of the rotating rod 22.

[0026] By starting the motor 21, the motor 21 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the small reel 23 to rotate synchronously, so that the small reel 23 reels the cable. During the reeling process, the cable drives the reel 14 to rotate, and the reel 14 drives the rotating shaft 13 to rotate synchronously. When the rotating rod 22 rotates, under the action of the limit bar 25, it drives the small reel 23 and the block 24 to rotate synchronously.

[0027] like Figure 2 、 Figure 3 As shown, the outer wall of the threaded rod 31 is threadedly connected to a slider 32, the outer wall of the slider 32 is slidably connected to the front of the base plate 1, the top of the slider 32 is fixedly connected to a movable plate 33, and the top of the movable plate 33 is plugged into the outer wall of the limit block 26.

[0028] By rotating the threaded rod 31, the slider 32 moves on the outer wall of the threaded rod 31, and the slider 32 drives the movable plate 33 to move synchronously, so that the outer wall of the limit block 26 is no longer plugged into the inner wall of the movable plate 33. Then the stop block 24 and the small reel 23 can be removed in turn, driving the limit bar 25 to slide on the inner wall of the rotating rod 22. The limit bar 25 guides the small reel 23 and the stop block 24, thereby facilitating the removal of the small reel 23 wound with the cable, thereby facilitating disassembly.

[0029] like Figure 2 、 Figure 5As shown, the bottom end of the right fixed frame 41 is fixedly connected to a motor 2 42, the output end of the motor 2 42 is fixedly connected to a bidirectional threaded rod 1 43, the outer wall of the bidirectional threaded rod 1 43 is rotatably connected to the inner wall of the fixed frame 41, the top of the outer wall of the bidirectional threaded rod 1 43 is fixedly connected to a driving wheel 44, the outer wall of the driving wheel 44 is transmission-connected to a transmission belt 45, the left part of the transmission belt 45 is transmission-connected to a driven wheel 46, the axis of the driven wheel 46 is fixedly connected to a bidirectional threaded rod 2 47, the outer wall of the bidirectional threaded rod 2 47 is rotatably connected to the inner wall of the left fixed frame 41.

[0030] By starting the second motor 42, the second motor 42 drives the bidirectional threaded rod 1 43 to rotate, so that the bidirectional threaded rod 1 43 drives the driving wheel 44 to rotate synchronously, the driving wheel 44 drives the transmission belt 45 to rotate, the transmission belt 45 drives the driven wheel 46 to rotate, and the driven wheel 46 drives the bidirectional threaded rod 2 47 to rotate.

[0031] like Figure 2 、 Figure 5 As shown, the upper and lower parts of the outer walls of the bidirectional threaded rod 1 43 and the bidirectional threaded rod 2 47 are both threadedly connected with a slider 2 48, the outer wall of the slider 2 48 is slidably connected to the inner wall of the fixed frame 41, the front end of the slider 2 48 is fixedly connected with a clamping plate 49, the front part of the clamping plate 49 is fixedly connected with an anti-wear protrusion 491, and the inner wall of the anti-wear protrusion 491 is fixedly connected with anti-wear convex strips in a circular array.

[0032] When the two-way threaded rod 1 43 and the two-way threaded rod 2 47 rotate, the slider 2 48 moves, and the slider 2 48 drives the clamping plate 49 to move synchronously, and the clamping plate 49 drives the anti-wear protrusion 491 to move synchronously, so that the outer wall of the anti-wear protrusion 491 contacts the outer wall of the rotating shaft 13, generating friction, thereby forming a certain resistance to the rotating shaft 13, limiting the rotation speed of the rotating shaft 13, and avoiding the difficulty in slowing down the rotation speed of the rotating shaft 13 due to inertia, thereby achieving the effect of speed limiting.

[0033] The working principle of the present invention is as follows: when in use, the multiple groups of cables wound on the reel 14 are wound on a number of small reels 23 respectively, and then the motor 1 21 can be started, the motor 1 21 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the small reel 23 to rotate synchronously, so that the small reel 23 can reel the cable. During the reeling process, the cable drives the reel 14 to rotate, and the reel 14 drives the rotating shaft 13 to rotate synchronously. After rotating for a period of time, the motor 2 42 is started, and the motor 2 42 drives the bidirectional threaded rod 1 43 to rotate, so that the bidirectional threaded rod 1 43 drives The driving wheel 44 rotates synchronously, the driving wheel 44 drives the transmission belt 45 to rotate, the transmission belt 45 drives the driven wheel 46 to rotate, the driven wheel 46 drives the two-way threaded rod 47 to rotate, thereby moving the slider 48, the slider 48 drives the clamping plate 49 to move synchronously, the clamping plate 49 drives the anti-wear convex piece 491 to move synchronously, so that the outer wall of the anti-wear convex piece 491 contacts the outer wall of the rotating shaft 13 to generate friction, thereby forming a certain resistance to the rotating shaft 13, limiting the speed of the rotating shaft 13, and avoiding the rotating shaft from being slowed down due to inertia. The rotation speed of the shaft 13 is difficult to slow down, which has the effect of speed limiting. Later, when the winding work is about to end, the motor 121 is turned off, and the anti-wear convex piece 491 is slowly squeezed toward the shaft 13, so that the outer wall of the anti-wear convex piece 491 is pressed against the outer wall of the shaft 13, thereby slowing down the rotation speed of the shaft 13 until the shaft 13 stops rotating. Due to the effect of frictional resistance, the rotation speed of the shaft 13 is always lower than the rotation speed of the rotating rod 22. Therefore, the problem that the shaft 13 is still rotating when the rotating rod 22 stops rotating can be avoided, which has the effect of braking. The small reel 23 can be removed by rotating the threaded rod 31 to make the slider 32 move on the outer wall of the threaded rod 31. The slider 32 drives the movable plate 33 to move synchronously, so that the outer wall of the limit block 26 is no longer plugged into the inner wall of the movable plate 33. Then the stop block 24 and the small reel 23 can be removed in turn, driving the limit bar 25 to slide on the inner wall of the rotating rod 22. The limit bar 25 guides the small reel 23 and the stop block 24, thereby making it convenient to remove the small reel 23 wound with the cable, which makes it easy to disassemble and greatly improves the user experience.
