[0030] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0031] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0033] See also Figures 1 to 7 , the utility model provides a friction enhanced integrated winch.

[0034] like Figures 1 to 3 As shown, in one embodiment of the present utility model,

[0035] The friction-enhanced integrated winch comprises a mounting base 1, a drum 2, a rocker 3 and a transmission device 4. The mounting base 1 comprises a base plate 11 and vertical plates 12 arranged on both sides of the base plate. A cable plate 21 and a gear plate 22 are arranged on the drum 2. A cable fixing device 23 is arranged on the cable plate 21, and a cable driving gear 24 is synchronously arranged on the gear plate 22.

[0036] like Figure 2-4 As shown: the transmission device 4 includes a transmission shaft 41 and a transmission gear 42, the two ends of the transmission shaft 41 are respectively fixed on the two vertical plates 12, the transmission gear 42 and the transmission shaft 41 rotate synchronously, the transmission gear 42 and the cable driving gear 24 are meshed, and a self-locking device 5 and a brake assembly 6 are also provided on the transmission shaft 41. The self-locking device 5 includes a self-locking ratchet 51 and a pawl 52. The self-locking ratchet 51 is clamped on the transmission shaft 41, and the pawl 52 is fixed on the vertical plate 12 where the self-locking ratchet 51 is located. The brake assembly 6 includes a plurality of brake pads 61, and each brake pad is sleeved on the transmission shaft 41.

[0037] like Figure 3-Figure 4As shown, there are two brake pads 61, and the two brake pads 61 are respectively against the self-locking ratchet 51, and the brake pads 61 are brass friction pads. The brass friction pads have the characteristics of fast heat absorption and heat dissipation, high temperature resistance, and wear resistance.

[0038] The rocker and transmission device in the existing winch are basically fixedly connected. In particular, in order to reduce the input transmission force, the lever arm of the rocker is designed to be very long in the entire device. The length of the rocker is basically larger than the transmission device and the drum in the entire winch. In order to solve the problem of handling and transferring, especially when transferring large quantities, the winch occupies a larger space, but the space utilization rate is low. In order to solve this problem, the rocker 3 and the transmission device 4 are detachably connected.

[0039] Specifically, Figure 5-Figure 6 As shown:

[0040] A connecting block 411 is disposed at the end of the transmission shaft 41 , a sleeve 31 is disposed at the end of the rocker 3 , a connecting slot 310 is disposed in the sleeve 31 , and the connecting block 411 is snap-connected in the connecting slot 310 .

[0041] The connecting block 411 is a regular hexagon, and the connecting slot 310 is also a regular hexagon with the same cross-sectional size as that of the connecting block 411 .

[0042] The connection block 411 is provided with two positioning holes 410 , and the sleeve 31 is provided with two connecting holes 311 corresponding to the positioning holes 410 . A screw 32 is provided between each positioning hole 410 and the corresponding connecting hole 311 for fixed connection.

[0043] By setting the connecting block 411 and the connecting slot 310, quick installation and disassembly can be achieved. After disassembly, the space occupied by a large number of products during transportation and transfer can be saved. When installing and using, it is only necessary to connect the connecting block 411 and the connecting slot 310, and then use the screw 32 to further fix it, and then it can be put into rotation and lifting.

[0044] The existing cable is provided with a clamping block at the end of the cable and then wound around the drum, which provides an insurance policy. If the tail end of the cable rotates and oscillates after long-term use, causing the clamping block to loosen and fall off, and there are no other protective measures, the cable may fall off during the transfer of the entire winch device, which may easily cause damage to the cargo. In order to avoid the above problem, a cable fixing device 23 is additionally designed.

[0045] Specifically, Figure 7 As shown: a cable hole 211 and a plurality of fixing holes 212 are provided on the cable plate 21, and a cable fixing device 23 is fixed on the fixing hole 212. In conventional equipment, only a plurality of circular cable holes 211 are provided without any extra fixing measures.

[0046] The cable hole 211 is a conventional circular hole, which is only used for passing cables. The area of ​​the fixing hole 212 is larger than that of the cable hole 211. Half of the fixing hole is for passing cables, and the other half of the fixing hole 212 is actually used to install the cable fixing device 23 to clamp the cables and increase the friction between the fixing hole 212 and the cables.

[0047] The fixing hole 212 is a straight slot type, and the cable fixing device 23 includes a bolt column 231, a wire pressing plate 232 and a locking nut 233. The wire pressing plate 232 is rotatably sleeved on the bolt column 231, and the bolt column 231 passes through one of the fixing holes 212. The end of the bolt column 231 is threadedly connected to the locking nut 233.

[0048] A protective cover 13 is also provided on the vertical plate 12. The self-locking ratchet 51 and the pawl 52 are located inside the protective cover 13. The protective cover 13 is used to isolate dust and water vapor and protect the internal gears and friction plates.

[0049] The present embodiment relates to a friction-enhanced integrated winch. By providing a cable fixing device, the wire pressing plate can fix the end position of the cable, increase the friction between the cable and the cable plate, and further restrict the cable to prevent it from loosening and falling off at the tail end, thereby improving the stability of the entire equipment and the safety of operation; a new brass friction plate is provided to increase the overall service life of the friction plate during the reverse lifting process, and can also increase the friction and improve the rotation efficiency of the operator; by providing a connecting block and a connecting slot, it can be quickly installed and disassembled. After disassembly, it can save the space occupied by a large number of products during the handling and transfer process. When installing and using, it only needs to be clamped and then further fixed with a screw.

[0050] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
