Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric winch technology, specifically to an electric winch that prevents the rope from loosening. Background Technology
[0002] An electric winch is a mechanical device that uses an electric motor to drive a drum to wind a cable, thereby pulling or lifting heavy objects. It boasts advantages such as strong and stable power, convenient and efficient operation, and high safety. It is used in automotive rescue, engineering construction, outdoor operations, and industrial production.
[0003] During the winding and unwinding process of an electric winch, it is crucial to maintain uniform tension on the cable. If the cable is not fully straightened before winding, uneven tension will occur when the cable winds around the drum, resulting in localized loose windings that will loosen under subsequent stress. Chinese Patent No. CN221971132U describes an electric winch for preventing rope loosening. It includes a base, a motor fixedly connected to the top right side of the base, a shaft seat fixedly connected to the top left side of the base, an anti-loosening component located in the middle of the shaft seat above the base, a storage component on the outside of the base, and a top cover rotatably connected to the rear side of the base. The anti-loosening component includes a turntable, with a bidirectional lead screw fixedly connected to the middle of the turntable. A square notch is provided in the middle of the base, and the right end of the bidirectional lead screw passes through the base and rotatably connects to the inside of the square notch. In use, the square notch, bidirectional lead screw, turntable, clamping ring, groove, electric telescopic rod, and pressure plate effectively secure the wound rope, preventing it from loosening or falling off.
[0004] The aforementioned electric winch for preventing rope loosening achieves this by compressing and limiting the wound cable. However, this method still cannot solve the problem of the cable not being fully straightened during winding and unwinding. This results in uneven cable slack during use, making it impossible to guarantee uniform traction force or ensure the rope remains straight during use, thus causing the rope to still appear "loose" during use and winding. Utility Model Content
[0005] In view of the above problems, an electric winch preventing rope body loosening is provided. A pressing-down component is matched with an upper lifting rod, and a driving component drives the pressing-down component and a lower pressing rod through a transmission component to adjust the extrusion force on the cable rope body according to the use state of a winch component, so as to straighten the cable rope body, fix and clamp the end of the cable rope body after the cable rope body is completely wound and unwound, and effectively avoid loose winding of the cable; when the clamping force between the lower pressing rod and the upper lifting rod is gradually reduced, a buffer member will push the lower pressing rod downward to contact with the outer surface of the cable rope body, so as to better straighten the cable rope body and absorb the vibration generated by the cable rope body during use.
[0006] To solve the problems in the prior art, the utility model provides an electric winch preventing rope body loosening, which comprises a mounting seat, and further comprises a driving component and a winch component arranged above the mounting seat;
[0007] The utility model further comprises a fixed frame fixedly mounted above the mounting seat, wherein an upper lifting rod and a lower pressing rod are horizontally arranged on the fixed frame right in front of the winch component, both ends of the upper lifting rod are fixedly connected with the fixed frame, and the lower pressing rod is vertically and movably arranged right above the upper lifting rod;
[0008] The top of the lower pressing rod is provided with the pressing-down component, a transmission component is arranged on the side, away from the driving component, of the winch component and the pressing-down component, and the winch component and the transmission component are sequentially arranged at the output end of the driving component;
[0009] The pressing-down component comprises a lower push rod fixedly arranged right above the lower pressing rod, a bidirectional threaded rod and a guide rod are horizontally arranged above the lower push rod, a group of pushing blocks capable of sliding along the extension direction of the bidirectional threaded rod and the guide rod are further arranged on the bidirectional threaded rod and the guide rod, and the bottom of each pushing block is in contact with the upper surface of the lower push rod.
[0010] Preferably, the lower push rod is arranged in a "mountain" shape, the inner walls of two grooves formed by inward recessing of the lower push rod are both arranged in a circular arc shape, and the bottom of the pushing block is semi-cylindrical to facilitate moving along the circular arc grooves.
[0011] Preferably, two ends of the guide rod are fixedly connected with the fixed frame, one end of the bidirectional threaded rod is rotationally connected with one side of the fixed frame, the other end of the bidirectional threaded rod transversely penetrates through the fixed frame to form a connecting part, and the end of the connecting part is connected with the transmission component.
[0012] Preferably, the transmission component comprises a driving gear arranged at the output end of the driving component and a transmission gear fixedly connected with the end of the connecting part, and a speed change gear located in the same vertical plane as the driving gear and the transmission gear is further arranged between the driving gear and the transmission gear.
[0013] Preferably, a bearing seat is horizontally provided in the middle of the gear and fixedly connected thereto, and a mounting part is vertically extended above the fixing frame to be connected to the bearing seat. Both the drive gear and the transmission gear are meshed with the gear.
[0014] Preferably, both ends of the pressure rod are fixedly connected to sliding blocks, and a set of vertical grooves that cooperate with the sliding blocks are vertically opened inside the fixing frame.
[0015] Preferably, a buffer is installed on the inner wall at the top of each vertical groove, and the bottom of each buffer is in close contact with the top of the sliding block directly below it.
[0016] The advantages of this utility model compared to the prior art are:
[0017] 1. The lowering component works in conjunction with the upper lifting rod, and the driving component drives the lowering component and the lowering rod to adjust the squeezing force on the cable body according to the use status of the winch component, thereby straightening the cable body and fixing and clamping the end of the cable body after it is fully wound and unwound, effectively avoiding the occurrence of cable tangling.
[0018] 2. As the clamping force between the lower pressure rod and the upper lifting rod gradually decreases, the buffer will push the lower pressure rod downward, ensuring that the bottom of the lower pressure rod is always in contact with the outer surface of the cable. This allows for better straightening of the cable and also absorbs vibrations generated during use, further preventing the cable from becoming loose. Attached Figure Description

Buffer component. Detailed Implementation
[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0027] See Figure 1 As shown, an electric winch for preventing rope loosening includes a mounting base 1, and a drive assembly 2 and a winch assembly 3 disposed above the mounting base 1.
[0028] It should be noted that drive assembly 2 consists of a drive motor and a reduction gear used in conjunction with the drive motor, and the winch assembly consists of a winch drum and a cable, with the winch drum installed at the output end of drive assembly 2. In use, the drive motor drives the winch drum to rotate through the reduction gear and its output end to wind or release the cable.
[0029] See Figure 1 and 2 As shown, it also includes a fixed frame 4 fixedly installed above the mounting base 1. The fixed frame 4 has an upper lifting rod 4a and a lower pressing rod 4b horizontally arranged in front of the winch assembly 3. Both ends of the upper lifting rod 4a are fixedly connected to the fixed frame 4, and the lower pressing rod 4b is vertically movably arranged directly above the upper lifting rod 4a.
[0030] It should be noted that the upper lifting rod 4a and the lower pressing rod 4b are designed to limit the height of the cable at the winch drum, preventing situations where successful winding is difficult due to rope bouncing and tangling.
[0031] See Figure 1 , Figure 2 and Figure 4 As shown, a pressing component is provided at the top of the pressing rod 4b, and a transmission component 5 is provided on the side of the winch assembly 3 and the pressing component away from the drive assembly 2. The winch assembly 3 and the transmission component 5 are arranged sequentially at the output end of the drive assembly 2.
[0032] It should be noted that both the winch assembly 3 and the transmission assembly 5 are powered by the drive assembly 2 to ensure the consistency of their operation, thereby achieving better control over the movement of the cable and straightening the cable.
[0033] See Figure 3-6As shown, the pressing-down assembly comprises a lower push rod (4b1) fixedly arranged directly above a lower pressing rod (4b), a bidirectional threaded rod (4c) and a guide rod (4d) are horizontally arranged above the lower push rod (4b1), a group of pushing blocks (4c1) capable of sliding along the extension direction of the bidirectional threaded rod (4c) and the guide rod (4d) is further arranged at the bidirectional threaded rod (4c) and the guide rod (4d), and the bottom of the pushing block (4c1) is in contact with the upper surface of the lower push rod (4b1).
[0034] It should be noted that, in use, the bidirectional threaded rod (4c) rotates, drives the pushing blocks (4c1) to move along the guide rod (4d) through external threads, the pushing blocks (4c1) will contact the lower push rod (4b1) during movement, so as to drive the lower push rod (4b1) and the lower pressing rod (4b) connected with the lower push rod (4b1) to move, adjust the clamping state of the lower pressing rod (4b) and an upper lifting rod (4a) on a cable body, and straighten the cable body at the same time.
[0035] See Figure 6 As shown, the lower push rod (4b1) is arranged in a "mountain" shape, inner walls of two grooves concavely formed inward in the lower push rod (4b1) are both arranged in a circular arc shape, and the bottom of the pushing block (4c1) is a semi-cylinder facilitating movement along the circular arc grooves.
[0036] It should be noted that the "mountain"-shaped lower push rod (4b1) is provided with two sections of grooves, which facilitates the two pushing blocks (4c1) to better push the lower push rod (4b1) when the cable body is completely wound and completely released, so that the lower pressing rod (4b) and the upper lifting rod (4a) tightly clamp the cable body, achieving the effect of preventing the cable body from slipping off or loosening.
[0037] Meanwhile, the circular arc arrangement of the inner walls of the grooves can realize clamping adjustment of different degrees on the cable body during winding or releasing of the cable body, and can also achieve the effect of regulating the cable body, facilitating use of the cable body.
[0038] See Figure 4 and Figure 5 As shown, two ends of the guide rod (4d) are fixedly connected with a fixing frame (4), one end of the bidirectional threaded rod (4c) is rotatably connected with one side of the fixing frame (4), the other end of the bidirectional threaded rod (4c) transversely penetrates through the fixing frame (4) to form a connecting part, and the end of the connecting part is connected with a transmission assembly (5).
[0039] See Figure 1-3 As shown, the transmission assembly (5) comprises a driving gear (5a) arranged at the output end of a driving assembly (2) and a transmission gear (5b) fixedly connected with the end of the connecting part, and a speed change gear (5c) located in the same vertical plane as the driving gear (5a) and the transmission gear (5b) is further arranged between the driving gear (5a) and the transmission gear (5b).
[0040] It should be noted that the drive gear 5a is the main drive gear connected to the output end of the drive assembly 2, and the speed change gear 5c is a component used to change the speed transmitted by the drive gear and then transmit that speed to the transmission gear 5b, so as to better clamp the cable to different degrees according to the state of the cable.
[0041] A bearing seat is horizontally provided in the middle of the gear 5c and fixedly connected thereto. The mounting part of the fixing frame 4 extends vertically above to form a mounting part connected to the bearing seat. The drive gear 5a and the transmission gear 5b are both meshed with the gear 5c.
[0042] See Figure 1 and Figure 5 As shown, both ends of the pressing rod 4b are fixedly connected to sliding blocks 4b2, and a set of vertical grooves that cooperate with the sliding blocks are vertically opened inside the fixing frame 4.
[0043] Each of the vertical grooves is equipped with a buffer 6 on the inner wall at the top, and the bottom of each buffer 6 is in close contact with the top of the sliding block 4b2 directly below it.
[0044] It should be noted that the buffer 6 consists of a buffer spring and a hard rubber plate. When in use, the vibration generated at the Range Rover rope will spread along the pressure bar 4b to the sliding block 4b2, and then be absorbed by the buffer 6 at the top of the sliding block 4b2, thereby reducing the vibration force of the Range Rover rope during use.
[0045] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
