Description

Technical Field

[0001] This utility model relates to the field of electric winch technology, and in particular to a portable electric winch. Background Technology

[0002] An electric winch is a mechanical device that uses an electric motor to drive and release cables. It is widely used in traction, towing, and lifting operations involving heavy objects. Installed on off-road vehicles, it can be used to pull vehicles out when they get stuck in mud, sand, or snow. Typically, one end of the cable is fixed to a nearby sturdy object, and the winch is activated to achieve self-rescue. It also plays an important role in rescuing other stranded vehicles, helping them to get out of trouble. In construction sites and mines, electric winches can be used in conjunction with cranes or elevators to lift small building materials and equipment parts, providing auxiliary lifting or traction. This can improve the convenience and efficiency of construction to a certain extent. Especially in areas with limited space that are not suitable for large lifting equipment, the flexibility of electric winches is even more obvious. To enable flexible use in various scenarios, a portable electric winch is needed.

[0003] Currently available portable electric winches mainly consist of a winch body, a motor, and a cable. The installation location of the winch is determined based on the actual usage scenario. The other end of the cable, with a hook, is connected according to specific operational needs, and the motor is started for traction. However, during use, the cable is prone to wear, breakage, or tearing due to repeated friction, bending, and excessive tension. If not addressed promptly, the cable may break during winch operation, leading to safety accidents. To solve these problems, existing technology only selects reliable cable products that meet the winch's rated tensile strength requirements to avoid safety hazards, without improving installation and disassembly. Installation and disassembly require numerous tools, involve complex procedures, and are time-consuming, failing to meet the convenience requirements for emergency use or temporary operations and thus not fulfilling the usage needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable electric winch, which aims to improve the existing technology by not improving the installation and disassembly process. When installation and disassembly are required, many tools are needed, the operation steps are complicated, and the time is long, which does not meet the requirements of convenience for emergency use or temporary work.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable electric winch, comprising a support frame, a motor fixedly connected to the left side of the support frame, a take-up winch fixedly connected to the output end of the motor, a cable fixedly and rotatably connected to the inner outer wall of the take-up winch, multiple fixed rods slidably connected around the bottom of the support frame, a pressing rod slidably connected inside the fixed rod, a limit shaft slidably connected to the bottom of the pressing rod, a spring fixedly connected to the outer wall of the limit shaft, a slot formed at the bottom of the outer wall of the pressing rod, two locking blocks rotatably connected to the front and rear sides of the slot, a locking block fixedly connected to the opposite side of the locking blocks, a threaded wire fixedly connected to the top of the outer wall of the fixed rod, a nut threadedly connected to the outer wall of the threaded wire, and a connecting mechanism provided at the front side of the cable, the connecting mechanism being used to fix the pulled object.

[0006] As a further description of the above technical solution:

[0007] The connecting mechanism includes a hook, with two connecting discs fixedly connected to the upper and lower rear sides of the hook. A vertical rod is slidably connected to the middle of the connecting discs, and a limit rod is slidably connected to the bottom of the vertical rod. A rotating shaft is rotatably connected to the top rear side of the hook, and a compression spring is fixedly connected to the middle of the outer wall of the rotating shaft. A limiting plate is rotatably connected to the front and rear sides of the outer wall of the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] Rotating blocks are fixedly connected to the front and rear sides of the outer wall of the nut, and a washer is fixedly connected to the bottom of the nut.

[0010] As a further description of the above technical solution:

[0011] Rotation grooves are provided on the front and rear sides of the bottom of the outer wall of the fixing rod, and an anti-slip pad is fixedly connected to the bottom of the locking block.

[0012] As a further description of the above technical solution:

[0013] A limiting base plate is fixedly connected to the front side of the support frame, and two limiting rods are fixedly connected to the middle of the front side of the limiting base plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when using the electric winch, the fixing rod is first placed in the predetermined position. The operator needs to lift the pressing rod, and the locking block will engage with the slot at the bottom of the pressing rod. As the pressing rod is lifted, the locking block rotates and opens, allowing the nut to rotate on the thread, quickly fixing the winch and improving work efficiency. When disassembling, the nut is rotated in the opposite direction and the pressing rod is pressed down. The spring retracts, and the locking block merges into the rotating slot, achieving quick disassembly, saving time, and making the operation efficient and convenient.

[0022] 2. In this utility model, during object traction operations, one end of the cable is placed inside the connecting plate, fixed by passing the cable through the upright, and then additionally fixed by the limiting rod. After the connection is completed, the limiting plate is pressed to apply pressure to the spring, and the hook is hung on the traction object. The tension of the spring prevents the hook from falling off during operation, ensuring the safety of the traction operation. Attached Figure Description

[0039] Working principle: In practical applications, when it is necessary to fix the electric winch, the fixing rod 6 should first be placed in the predetermined position. Under the tension of the spring 9, the operator needs to lift the pressing rod 7 upward. The locking block 11 at the bottom of the locking block 12 will accurately lock into the locking groove 10 opened at the bottom of the pressing rod 7. As the pressing rod 7 is lifted upward, the locking block 12 will rotate and open accordingly, so that the nut 14 can rotate on the thread 13, which can quickly fix the electric winch and greatly improve work efficiency. When it is necessary to remove the electric winch, the operator only needs to rotate the nut 14 in the opposite direction and press the pressing rod 7 at the same time. The spring 9 will retract accordingly, and the locking block 12 will merge into the rotating groove 17 opened at the bottom of the fixing rod 6, realizing quick removal and saving a lot of time. The whole operation process is both efficient and convenient.

[0040] When performing object traction operations, place one end of cable 5 into the internal space of the connecting plate 202, and use the upright 203 to pass through this end of cable 5 to ensure that cable 5 can be firmly fixed on the connecting plate 202. Then, use the limiting rod 204 to further fix cable 5. After the connection process is completed, press the limiting plate 207 to apply appropriate pressure to the compression spring 206, and hang the hook 201 on the object to be traction. The tension of the compression spring 206 will play a role in the operation, supporting the limiting plate 207 upward, thereby preventing the hook 201 from accidentally falling off during traction, avoiding possible dangerous situations in traction operations, and ensuring the safety of the entire operation process.
