Description

Technical Field

[0001] This utility model belongs to the field of rope lifting winches, specifically a rope lifting winch device. Background Technology

[0002] A rope winch is a mechanical device that lifts or lowers heavy objects by changing the direction of force. It is widely used in self-protection and traction devices for vehicles and ships. Its basic principle is to use a rope or chain that rotates around a spool to lift heavy objects or change the direction of force transmission. When the handle or lever of the winch is turned, the internal planetary reduction gear converts the rotational force into a linear force transmitted along the rope, thus easily lifting heavy objects. Depending on the power source, winches can be divided into manual winches and electric winches. Traditional manual winch devices generally use a single gear transmission method in their design and construction. The characteristic of this transmission method is that the transmission ratio is fixed and cannot be adjusted according to actual needs. Therefore, when the operator needs to lift heavy objects using the winch, a large torque must be applied to complete the operation. In this case, the operator's labor intensity increases significantly, which affects work efficiency. At the same time, due to the large torque, the operation process also becomes more strenuous, resulting in low overall work efficiency and failing to meet the need for convenient operation.

Detailed Implementation

[0014] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0015] Example 1 like Figure 1-8As shown, this is the first embodiment of the present invention. This embodiment provides a rope lifting winch device, including an anchor plate 100 for supporting and installing the entire device. A housing 200 is installed on the front of the anchor plate 100. The housing 200 includes a fixing base 210, an end cap 220 located on the front of the fixing base 210, and a through groove 230 formed on the upper surface of the end cap 220. The winch assembly 300 includes a coil sleeve 310 sleeved on the surface of the end cap 220, an internal toothed ring 320 located at one end of the coil sleeve 310, and a rope locking disc 330 located at the other end of the coil sleeve 310. The power assembly 400 includes a power unit located inside the fixing base 210. The drive assembly 500 comprises a first gear 410 at the front end of the cavity, a first ratchet 420 located inside the cavity of the first gear 410, a second gear 430 located on the back of the first gear 410, a third gear 440 meshing with the second gear 430, a fourth gear 450 located at the upper end of the cavity of the fixed seat 210 and meshing with the third gear 440, a second ratchet 460 located inside the cavity of the fourth gear 450, and a fifth gear 470 fixed to the front of the second ratchet 460. The through slot 230 of the fifth gear 470 meshes with the internal gear ring 320, and the first gear 410 meshes with the fifth gear 470.

[0016] like Figure 1-8 As shown, the anchor plate 100 is fixed on the support point tripod and connects the lifting rope and the webbing. The back of the anchor plate 100 has a pin hole, which can be quickly installed on the rescue tripod through the pin. It is suitable for lifting needs in a variety of complex environments. The locking rope reel 330 has a V-shaped groove to increase the friction with the rope, thereby effectively preventing the rope from falling off. After the rope is wound on the surface of the reel 310, it is wound inside the locking rope reel 330. The outer shell 200 provides protection and installation space for the power component 400. The drive assembly 500 also includes a drive shaft 510 and a handle 520. The handle 520 is mounted on the drive shaft 510. The drive shaft 510 rotates clockwise, driving the first ratchet 420 and the second gear 430. The ratchet teeth on the surface of the first ratchet 420 rotate clockwise, resulting in no movement between them and the first gear 410. The clockwise rotation of the second gear 430 drives the third gear 440 to rotate counterclockwise. The counterclockwise rotation of the third gear 440 drives the fourth gear 450 to rotate clockwise. The internal tooth groove in the fourth gear 450 engages the second ratchet 460, enabling it to drive the fifth gear 470 to rotate clockwise. The clockwise rotation of the fifth gear 470 drives the internal tooth ring 320 to rotate, thereby driving the sleeve 310 to rotate. The clockwise rotation of the fifth gear 470 also drives the first gear 410 to rotate counterclockwise. The first gear 410 and the first ratchet 420 perform no movement between them, thus achieving effortless rotation. Rotating the transmission shaft 510 counterclockwise drives the first ratchet 420 and the second gear 430 to move counterclockwise. The ratchet teeth of the first ratchet 420 engage the internal tooth groove in the first gear 410, causing it to rotate counterclockwise. The counterclockwise movement of the first gear 410 directly drives the fifth gear 470 to rotate clockwise. The clockwise rotation of the fifth gear 470 drives the sleeve 310 to rotate through the internal tooth ring 320. The other gears perform ineffective movements, thereby achieving higher efficiency rotation.

[0017] Example 2 Reference Figure 1 , 2 3 and 8 are the second embodiment of this utility model, which is based on the previous embodiment.

[0018] In this embodiment, the fixing seat 210 is fixedly connected to the anchor plate 100 by bolts, and the fixing seat 210 is fixed to the end cover 220 by bolts.

[0019] The internal toothed ring 320 is fixedly connected to the sleeve 310, the sleeve 310 is rotatably connected to the end cover 220 through a bearing, and the rope locking disc 330 is fixed to the end of the end cover 220 away from the fixed seat 210 by bolts.

[0020] The winch assembly 300 also includes a guide ring 340, which is fixed to one end of the front side of the anchor plate 100.

[0021] like Figure 1 , 2 As shown in Figures 3 and 8, the anchor plate 100, the outer shell 200, and the winch assembly 300 are fixed together by bolts for easy disassembly and maintenance. The fixing seat 210 and the end cover 220 adopt a detachable structure for easy maintenance of the internal power assembly 400. The guide ring 340 is fixed to the front of the anchor plate 100 to provide a guiding path for the rope and prevent tangling or deviation. The coil sleeve 310 is connected to the end cover 220 through a bearing to ensure smooth rotation and reduce friction loss.

[0022] Example 3 Reference Figure 1-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0023] In this embodiment, the inner cavities of the first gear 410 and the fourth gear 450 are both provided with internal tooth grooves, and they mesh with the first ratchet 420 and the second ratchet 460 respectively. The power assembly 400 is rotatably connected to the inner wall of the fixed seat 210 through a bearing.

[0024] The drive assembly 500 includes a drive shaft 510 and a handle 520 located on the front of the locking cord reel 330. One end of the handle 520 extends through the inner cavity of the drive shaft 510 and engages with the inner cavity of the drive shaft 510.

[0025] The end of the drive shaft 510 away from the handle 520 passes through the end cover 220 and the first ratchet 420 and extends into the inner cavity of the second gear 430, and is connected to the inner cavity of the second gear 430 in a drive connection.

[0026] like Figure 1-8 As shown, the handle 520 is inserted into the inner cavity of the drive shaft 510, which can rotate the drive shaft 510, thereby driving the power component 400 to operate. The handle 520 can also be replaced with an electric drill. The output shaft of the electric drill is inserted into the inner cavity of the drive shaft 510. The rotation of the electric drill output shaft drives the drive shaft 510 to rotate. By controlling the forward and reverse rotation of the drive shaft 510 to drive the power component 400, two lifting modes can be achieved: labor-saving lifting and high-efficiency lifting. The slow release of the rope can be controlled, which can be used for different scenario needs.

[0027] In use, first, fix the anchor plate 100 to the tripod at the support point, connect the lifting rope and the webbing, then wrap the lifting rope around the surface of the sleeve 310. Rotate the drive shaft 510 clockwise or counterclockwise via the handle 520. The rotation of the drive shaft 510 will sequentially drive the gears in the power assembly 400 to mesh and transmit power. When rotating clockwise, the first ratchet 420 and the first gear 410 make no effort to move, while the second gear 430 drives the subsequent gear chain to achieve effortless rotation. When rotating counterclockwise, the ratchet teeth of the first ratchet 420 engage the first gear 410, achieving more efficient rotation. This process... In the process, the engagement of the fifth gear 470 with the internal gear ring 320 allows the coil sleeve 310 to rotate smoothly, thereby winding up the lifting rope. The lifted rope is then wound around once inside the rope locking disc 330, which secures the rope and prevents it from falling off. The guide ring 340 ensures that the rope will not tangle or shift during the lifting process, guaranteeing the stability and safety of the operation. In addition, the design of the drive component 500 allows the handle 520 to be operated manually or replaced with power tools such as an electric drill to adapt to the lifting needs in different scenarios, further improving the practicality and flexibility of the device.
