Description

Technical Field

[0001] This utility model relates to the field of rope throwing technology, specifically to an electromagnetic rope throwing device. Background Technology

[0002] A line thrower is a device that uses air pressure or gunpowder to project a rope over a long distance to a target location, helping to establish a temporary connection. It is primarily used for heeling operations, throwing the cable towards a dock or other vessels. Its core function is to transmit tension through a lightweight heeling line, delivering the heavy mooring line to the dock bollard. When there is a significant distance between the vessel and the dock, directly delivering the heavy cable is difficult; a heeling line can establish a connection channel first. Compared to small boats or mechanical devices carrying mooring lines, heeling lines can quickly complete the mooring. The heeling line usually has a hard rubber, sandbag, or metal ball at its front end as a heeling head, providing launching inertia and facilitating directional flight during casting; the rear end of the heeling line has a single loop that can be secured to the wrist or railing to prevent slippage.

[0003] Traditional rope throwers use air pressure or gunpowder, requiring gas cylinders and repeated refilling for reuse. This is inconvenient, and the cylinders and gunpowder pose safety hazards. While utility model patent CN217929973U provides an electromagnetic rope thrower capable of multiple re-launches, it doesn't address the retrieval of the lead cable after throwing, leaving room for further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electromagnetic rope thrower that solves the technical problems of traditional rope throwers being unable to be quickly reused and difficult to retrieve. To achieve the above objective, the technical solution provided by this invention is as follows.

[0005] An electromagnetic rope thrower includes a housing, and the housing contains:

[0006] An electromagnetic transmitting device, comprising a transmitting tube with a coil sleeved on its outer periphery;

[0007] A cable take-up device is located at the end of the launching tube and includes a take-up roller connected to the output shaft of a drive motor; the drive motor is connected to the inside of the take-up roller via a clutch mechanism.

[0008] The circuit control device includes a circuit board and a battery compartment. The circuit board is electrically connected to the coil and the drive motor, and the contacts of the battery compartment are connected to the circuit board.

[0009] A power switch is installed through the housing, and the contacts of the power switch are connected to the circuit board.

[0010] Furthermore, the clutch mechanism includes a sleeve fitted onto the output shaft of the drive motor. The sleeve penetrates the housing and is threadedly connected to it. A rotating handle is provided at the end of the sleeve located outside the housing. A gear ring is provided on the inner wall of the sleeve located inside the housing. A drive gear is coaxially provided on the output shaft of the drive motor. A driven gear is provided on the outer wall of the sleeve, and a take-up gear is provided on the inner wall of the take-up roller. The drive gear is adapted to the gear ring, and the driven gear is adapted to the take-up roller.

[0011] Furthermore, multiple coils are provided, the emitting tube is transparent, and infrared lamp beads and sensing crystals are provided in the gaps between multiple adjacent coils. The infrared lamp beads and sensing crystals are electrically connected to the circuit board.

[0012] Furthermore, a trigger-type safety switch is also provided on the outside of the housing, with the contacts of the safety switch located between the battery compartment contacts and the circuit board contacts.

[0013] Furthermore, a support cylinder extends inward from the housing, and the drive motor is installed inside the support cylinder. The outer periphery of the support cylinder is fitted onto the inner side of the bearing, and the inner side of the take-up roller is in contact with the outer side of the bearing.

[0014] Furthermore, a wire guide is also provided between the take-up roller and the launch tube.

[0015] Furthermore, the wire guide includes a wire guide screw, the axial direction of which is parallel to the axial direction of the take-up roller. A wire guide block is sleeved on the outer periphery of the wire guide screw, and the wire guide block has a wire guide hole arranged radially along the wire guide screw. A guide post is arranged inside the housing parallel to the axial direction of the wire guide screw. The wire guide block has a guide through hole adapted to the guide post. A slider adapted to the wire guide screw is rotatably arranged inside the wire guide block.

[0016] Furthermore, a cover plate is provided on the side wall of the housing, and the cover plate is detachably connected to the housing. Opening the cover plate can expose at least one of the following mechanisms: support cylinder, cable guide, take-up roller, battery compartment, etc.

[0017] Furthermore, the circuit board is also electrically connected to an LED display screen, which is embedded in the housing and used to display the battery level.

[0018] Furthermore, a projectile is installed inside the launch tube, and a guide cable is connected to the tail end of the projectile. The end of the guide cable away from the projectile passes through the launch tube and the cable routing hole in sequence, then winds around the take-up roller and is fixed to the take-up roller.

[0019] The advantages and beneficial effects of this utility model are as follows: By replacing traditional pneumatic or gunpowder power with an electromagnetic launch device, the risks of cylinder explosions and gunpowder storage are avoided. A trigger-type safety switch prevents accidental launch. This rope launcher eliminates the need for repeated filling of gunpowder or compressed gas; battery power enables rapid launching, significantly improving operational efficiency. It also integrates a cable retrieval system, using a rotating handle to control the engagement of the sleeve with the drive motor's gears, allowing for rapid switching between launching and retrieval modes. A cable guide ensures the cable is evenly wound onto the take-up roller. The launch tube is equipped with infrared LEDs and a sensing crystal to switch the coil's energization status efficiently and conveniently. A removable cover exposes components such as the battery compartment and take-up roller, facilitating quick battery replacement, drive motor maintenance, or cable replacement.

[0029] Example 2

[0030] An electromagnetic rope thrower, based on embodiment 1, includes a clutch mechanism comprising a sleeve 8 fitted onto the output shaft of a drive motor 5.
