Description

Technical Field

[0001] This utility model relates to the field of cable laying technology using cable reels, and specifically to a device to prevent cable reels from flying off. Background Technology

[0002] During cable laying, cable reels sometimes experience uncontrolled rotation due to external forces, commonly known as "flying discs." Due to inertia, the flying disc phenomenon persists even after the external force disappears. Flying discs cause irregular rotation of the cable reel, leading to cables flying off the reel, reducing construction efficiency, and posing a risk of mechanical injury to workers. Currently, there is no dedicated device to prevent cable reel flying discs during construction. When a flying disc is imminent, manually reducing the reel's rotation speed is ineffective due to the large mass of the cable, ultimately resulting in a significant amount of cable falling to the ground, potentially causing injury to personnel attempting to intervene. Utility Model Content

[0003] The purpose of this utility model is to provide a device to prevent cable reel from flying off the reel. This device can effectively prevent cable reel from flying off the reel, reduce the risk of personnel injury caused by excessive speed of the cable reel, and reduce the extra labor intensity of reorganizing the cable after the cable cannot be laid normally due to the disordered sequence of the cable coming off the cable reel.

[0004] The aforementioned anti-cable reel / flying disc device includes a frame, a connecting mechanism, a triggering device, and a deceleration device;

[0005] A connecting mechanism is provided on one side of the frame, which fixes the frame to the wire feeding reel rotating frame so that it can rotate with the wire feeding reel rotating frame;

[0006] The frame is equipped with a triggering device and a deceleration device. The deceleration device includes a deceleration rod, a deceleration block, and a locking block. The deceleration rod is installed in the frame through a guide groove, and a deceleration block is fixedly installed on its lower end. The deceleration block can slide downwards with the deceleration rod and contact the ground. The upper part of the deceleration rod is located above the guide groove, and a locking block is installed on it. The triggering device controls the locking and releasing of the locking block on the deceleration rod through a switch, so that the deceleration rod can be fixed in the frame or slide downwards based on the guide groove.

[0007] The aforementioned anti-cable reel / flying disc device further includes an anti-detachment device, which comprises a spring I, an anti-detachment rod, and a locking mechanism. The frame contains an anti-detachment rod groove with an open upper end. The lower end of the spring I is located within the anti-detachment rod groove and connected to its bottom surface. The anti-detachment rod is placed within the groove, with its lower end connected to the upper end of the spring I. A locking mechanism is provided on the side wall of the anti-detachment rod, locking the rod and fixing it within the groove. At this time, the spring I is in a compressed state. The triggering device can activate the locking mechanism to unlock, causing the anti-detachment rod to slide upwards along the groove under the action of the spring I, extending beyond the groove.

[0008] The triggering device is an electromagnetic push-pull rod, with both ends of the push rod extending out from both ends. In its natural state, one end of the push rod is positioned below the locking block, supporting it, while the other end corresponds to the locking mechanism. When the triggering device is activated, the push rod moves towards the locking mechanism, contacting and triggering it, while simultaneously disengaging from the locking block. The electromagnetic push-pull rod can be a LY1264 electromagnetic push-pull rod, or other push-pull rods from the prior art.

[0009] The locking mechanism includes a locking groove, a locking pin, a spring II, and a locking pin groove; the anti-detachment rod groove is provided with a locking groove at the corresponding triggering device; the side wall of the anti-detachment rod is provided with a locking pin groove, and the locking pin groove is provided with a spring II and a locking pin; in the natural state, the locking pin extends out of the locking pin groove and inserts into the locking groove under the elastic force of the spring II, locking the locking groove so that the anti-detachment rod cannot be raised.

[0010] The triggering device is controlled by a remote control switch.

[0011] The connecting mechanism includes an upper clamping rod, a lower clamping rod, and bolts; the wire feeding reel rotating frame is provided with connecting plates corresponding to the upper and lower clamping rods, and the upper and lower clamping rods and the connecting plates are provided with corresponding screw holes. The upper and lower clamping rods and the connecting plates are fixedly connected by bolts, thereby fixing the connecting mechanism on the wire feeding reel rotating frame.

[0012] The bottom surface of the deceleration block is provided with a buffer pad made of elastic material.

[0013] The bottom surface of the cushioning pad is wavy.

[0014] The cushioning pad is made of rubber.

[0015] The working principle of this utility model is as follows:

[0016] The cable reel is fixed to the cable reel rotating frame, and the anti-cable reel slippage device is also fixed to the cable reel rotating frame via a connecting mechanism, rotating with the cable reel rotating frame. When the cable reel rotates too fast, it is manually judged. If the cable bends in front of the cable reel and does not travel in a straight line, the trigger device is activated by the remote control switch to disengage from the locking block, causing the deceleration rod to fall. The deceleration block and buffer pad contact the ground to create frictional resistance, reducing the speed of the cable reel. At the same time, the trigger device is activated and provides a pushing force to the locking pin, causing it to overcome the elastic force of spring II and enter the locking pin groove. The anti-slip rod rises under the action of spring I, blocking the cable from slipping outward.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model has a scientific and reasonable structural design. When the cable reel rotates abnormally, the triggering device will cause the deceleration rod to disengage and contact the ground, reducing the speed of the cable reel. At the same time, the anti-disengagement device will activate and the anti-disengagement rod will rise, fixing the cable to the cable reel. This effectively reduces the risk of personnel injury caused by excessive speed of the cable reel, and reduces the extra labor intensity of sorting the cables after the cable cannot be laid normally due to the disordered sequence of the cables disengaging from the cable reel.
