Description

Technical Field

[0002] The crawler-type automatic cable retracting and releasing device is a mechanical device that integrates the functions of cable winding, storage and release. It is mainly installed at the tail or specific position of the crawler-type equipment. Through the internal mechanical structure, it can automatically reel and release the cable, thereby ensuring that the cable can remain orderly and untangled during the movement or operation of the crawler-type equipment, and maintain an appropriate distance from the equipment to avoid being crushed by the crawler tracks or scratched by other obstacles. The device can automatically reel and release the cable, thereby simplifying the cable management process and reducing the labor intensity of the operator. The automatic cable retracting and releasing device can ensure that the cable is not crushed by the crawler tracks or scratched by other obstacles during the movement or operation, thereby extending the service life of the cable. The automatic cable retracting and releasing device reduces the safety hazards caused by cable entanglement, confusion or damage, and ensures the safety of the crawler-type equipment during operation. By reducing the potential risks of operators in managing cables, the safety of the overall working environment is improved.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) When the soil on the ground is uneven, the operator starts the hydraulic cylinder to drive the connecting frame to move downward. The connecting frame drives the supporting frame to rotate downward through the cooperation of the latch and the hollow bar, thereby driving the two leveling rollers to move down to the ground. At the same time, the operator starts the servo motor to drive the worm to rotate, and the worm drives the worm wheel to drive the rotating rod to rotate. When the rotating rod rotates, it drives the two first shaft rods to rotate along the inside of the two first shaft sleeves. When the two first shaft rods rotate, they drive the two leveling rollers to rotate, and start the chassis to drive the two crawlers to move, so that the device can be controlled to level the land, so that the two crawlers can be stably supported on the ground to prevent the device from tilting;

[0016] (2) When disassembling the saturated reel, the operator starts the driving motor to run forward. When the driving motor runs forward, it drives the first bevel gear to rotate. The first bevel gear drives the second shaft rod to rotate inside the two second shaft sleeves through the second bevel gear. When the second shaft rod rotates, it drives the two threaded rods to rotate. When the two threaded rods rotate, they drive the two threaded sleeves to move back and forth. When the two threaded sleeves move, they both drive the limit blocks to slide along the inside of the limit groove, thereby improving the stability of the two threaded sleeves when they move. When the two threaded sleeves move back and forth, they drive the two moving rods to move back and forth. When the two moving rods move, they both drive the first sliding block to slide along the inside of the first sliding groove, thereby improving the stability of the two moving rods when they move. When the two moving rods move back and forth, they drive the two first racks to move back and forth through the two connecting rods. When the two first racks move back and forth, they drive the two second racks to move toward each other through the two transmission gears.

[0017] When the two second racks move toward each other, they drive the two transmission bars to move toward each other. When the transmission bars move, they drive the second slider to slide along the inside of the second slide slot, thereby improving the stability of the two transmission bars when moving. When the two transmission bars move toward each other, the two contact blocks push the two rectangular rods to move upward along the inside of the two rectangular sliding sleeves, and at the same time squeeze the two springs. When the two rectangular rods move upward, they drive the two lifting frames to move upward to support the two positioning cylinders, thereby lifting the reel as a whole; when the two moving rods move back and forth, they also drive the left moving platform and the right moving platform to move back and forth, thereby driving the left clamping rod and the right clamping rod to withdraw from the inside of the two positioning cylinders to release the limit, thereby quickly completing the disassembly of the reel;

[0018] (3) When fixing a new reel, the operator places the positioning cylinders at both ends of the new reel on the two lifting frames, and then the operator starts the driving motor to run in the reverse direction. When the driving motor runs in the reverse direction, the two threaded sleeves are driven to move toward each other through the two threaded rods. When the two threaded sleeves move toward each other, the left moving platform and the right moving platform are driven to move toward each other through the two moving rods, thereby driving the left clamping rod and the right clamping rod to be inserted into the interior of the two positioning cylinders for limited installation; while the two moving rods move toward each other, they will also drive the two first racks to move toward each other through the connecting rod. When the two first racks move toward each other, the two second racks are driven to move back and forth through the two transmission gears. When the two second racks move back and forth, they drive the two transmission bars to move back and forth, so that the two transmission bars no longer push the two contact blocks, thereby driving the two rectangular rods to move downward under the elastic force of the two springs. When the two rectangular rods move downward, they drive the two lifting frames away from the two positioning cylinders to prevent the two lifting frames from affecting the rotation of the reel; when in use, the operator starts the retracting and discharging motor to run forward and reverse, thereby driving the reel to retract and release the cable.

[0019] (4) The crawler-type automatic cable retracting and releasing device can conveniently disassemble and assemble the reel, and can level the land to avoid the overall tilt of the device caused by uneven land, thereby ensuring the cable retracting and releasing effect.
