[0046] Please refer to Figures 1 to 6 The present embodiment provides a winch device for hoisting a water-taking robot 7, comprising a hanger 1, a pulley 2, a winch 3, a crossbar 4 and two groups of hoisting rope assemblies 5; the pulley 2 is arranged on the hanger 1 and can rotate relative to the hanger 1; the winch rope 31 of the winch 3 passes through the pulley 2, and the end is connected with the crossbar 4; the two groups of hoisting rope assemblies 5 are symmetrically arranged on opposite sides of the crossbar 4, and the two groups of hoisting rope assemblies 5 are used for detachable connection on opposite sides of the water-taking robot 7.

[0047] The hanger 1 is the supporting structure of the whole device, which is stably installed in a proper position, and in the present embodiment, it can be installed on the chassis of the drainage vehicle. The pulley 2 is supported on the hanger 1 through a shaft, and rotates around itself through the shaft, thereby guiding the movement of the winch rope 31. The rotation of the winch 3 can realize the lifting control of the crossbar 4 and the water-taking robot 7 hoisted thereon.

[0048] Since the crossbar 4 has a certain length, which is adapted to the length or width of the robot, so that the two hoisting rope assemblies 5 located on both sides thereof can avoid the shell of the water-taking robot 7 when hanging down, thereby avoiding the abrasion problem caused by the direct contact of the branch rope 511 with the edge of the robot in the existing hoisting mode.

[0049] Please refer to Figure 2 and Figure 3In the present embodiment, the hoisting rope assembly 5 comprises a first connecting ring 52 and a hoisting rope 51, the first connecting ring 52 is connected with the horizontal bar 4 by bolts, the hoisting rope 51 is connected with the first connecting ring 52, the hoisting rope 51 extends vertically, and the lower end of the hoisting rope 51 is provided with a hook buckle 54 which is detachably connected with the water taking robot 7. The first connecting ring 52 is made of high-strength alloy material to ensure that it can withstand sufficient tension without deformation or breakage during hoisting. The first connecting ring 52 has a protruding part with a threaded hole, and the bolt can be fastened with the horizontal bar 4 by matching the threaded hole. The protruding part of the first connecting ring 52 can abut against the bottom or side wall of the horizontal bar 4. The hook buckle 54 adopts a quick locking and releasing mechanism, which can be easily and detachably connected with the connecting point (such as the lifting ring 71) on the water taking robot 7.

[0050] Please refer to Figure 4 and Figure 5 In the present embodiment, the hoisting rope assembly 5 further comprises a second connecting ring 53, and the hoisting rope is connected with the first connecting ring 52 through the second connecting ring 53. The second connecting ring 53 is introduced as an intermediate connection between the hoisting rope 51 and the first connecting ring 52, so that the first connecting ring 52 and the hoisting rope 51 form an indirect connection. The second connecting ring 53 is also made of high-strength alloy material to ensure the stability and safety of the connection. The second connecting ring 53 and the first connecting ring 52 are connected in series to form an 8-shaped shape. Optionally, one or both of the second connecting ring 53 and the first connecting ring 52 is a detachable structure to facilitate the connection of the connecting ring. In some embodiments, the connecting ring can also be connected without being detachable.

[0051] Please refer to Figure 5 Preferably, the second connecting ring 53 is a detachable structure. The second connecting ring 53 comprises a U-shaped ring 531 and a connecting pin 532, the U-shaped ring 531 has two threaded holes on its two sides, the connecting pin 532 is threadedly connected with the two threaded holes and passes through the first connecting ring 52. This design can easily remove or replace the second connecting ring 53 and the hoisting rope 51 thereon.

[0052] Please refer to Figure 3 In the present embodiment, the hoisting rope assembly 5 further comprises a locking member 55, the locking member 55 comprises a U-shaped bolt 551 and a locking plate 552, the locking plate 552 has two through holes, the U-shaped bolt 551 passes through the two through holes and locks the hoisting rope 51 by matching two nuts 553. The hoisting rope 51 is first hung on the first connecting ring 52. Then, the two through holes of the locking plate 552 are aligned with the hoisting rope 51 and placed. Next, the two arm portions of the U-shaped bolt 551 are respectively passed through the two through holes of the locking plate 552 and made to surround the hoisting rope 51. Finally, the nuts 553 are installed at the ends of the two arm portions respectively, and the U-shaped bolt 551 is fastened by rotating the nuts 553, so that the hoisting rope 51 can be firmly locked at the position close to the connecting ring, greatly improving the stability of the hoisting rope 51.

[0053] It should be noted that in the embodiment without the second connecting ring 53, the hoisting rope 51 can be hung on the first connecting ring 52, and the connection between the hoisting rope 51 and the first connecting ring 52 is locked by the locking member 55. In the embodiment with the second connecting ring 53, the hoisting rope 51 is hung on the second connecting ring 53, and the connection between the hoisting rope 51 and the second connecting ring 53 is locked by the locking member 55.

[0054] It should be noted that the hoisting rope 51 is usually made of high-strength steel wire to ensure that it can withstand large tension and pressure. In order to further enhance the fixing effect of the hoisting rope 51, we can flexibly set multiple locking members 55 at different positions of the hoisting rope 51. Figure 3 It is shown that the connection between the hoisting rope 51 and the first connecting ring 52 has two locking members 55. These locking members 55 can accurately lock the hoisting rope 51 at a specific position, effectively preventing the hoisting rope 51 from slipping or falling off during hoisting. By adopting this multi-locking member 55 design, not only the stability of the hoisting rope 51 is improved, but also the reliability and safety of the winch device under various complex working conditions are ensured.

[0055] Please refer to Figures 3 to 5 In this embodiment, the hoisting rope 51 has two branch ropes 511, and each branch rope 511 has a hook buckle 54 connected to the lower end. The middle part of the hoisting rope 51 is hung on the connecting ring, and the two ends of the hoisting rope 51 naturally fall to form two branch ropes 511, which can jointly bear the weight of the object, thereby improving the stability of the hoisting process. Figure 4 It is shown that the crossbar 4 is along the width direction of the water taking robot 7, and the two branch ropes 511 are along the length direction of the water taking robot 7.

[0056] Please refer to Figure 6 In this embodiment, the water taking robot 7 has two left and right track wheels, and the outer wall of the track wheel shell is provided with a lifting ring 71, one lifting ring 71 corresponding to one hook buckle 54, and the winch device has four lifting rings 71 and four hook buckles 54. The inside of the track wheel shell has a transmission assembly and a motor, and the transmission assembly drives the track to rotate. The track wheel shell serves as a support and protection structure for the track, and is usually made of solid metal or alloy materials to ensure its durability and stability in harsh environments. The lifting ring 71 is arranged on the outer wall of the track wheel shell and can be fixed on the shell by welding or other firm connection methods.

[0057] Please refer to Figure 1 , Figure 2 and Figure 4In this embodiment, the top of the hanger 1 has a receiving opening 11, and the pulley 2 is located in the receiving opening 11 and connected to the top of the hanger 1 through a support 12, wherein the pulley 2 can rotate relative to the support 12, and the pulley 2 can be supported on the support 12 through a shaft. The winch 3 is arranged on the side wall of the hanger 1 and located obliquely below the pulley 2. The design of the receiving opening 11 enables the pulley 2 to be compactly installed on the top of the hanger 1, and the winch 3 is located obliquely below the pulley 2, which saves installation space.

[0058] Referring to Figure 2 and Figure 4 In this embodiment, the support 12 is located in the receiving opening 11, and the end of the support 12 away from the pulley 2 has a clamping groove 121 which is clamped and welded with the upper edge and the lower edge of the receiving opening 11. Through the clamping and welding between the clamping groove 121 and the edge of the receiving opening 11, a stable connection between the support 12 and the hanger 1 is achieved, which can withstand greater tension and torque, thereby improving the overall structural strength of the winch device. In some embodiments, the clamping groove 121 and the edge of the receiving opening 11 can also be bolted.

[0059] Referring to Figure 7 In this embodiment, the winch device further comprises a rotating member 6, and the end of the winch rope 31 is connected to the crossbar 4 through the rotating member 6, and the rotating member 6 is used to rotate the crossbar 4 left and right. The rotating member 6 can be a connecting component with a bearing or a sliding mechanism to ensure that the crossbar 4 can move smoothly and stably during rotation. The winch device can allow the crossbar 4 to rotate left and right under manual operation to adjust the position of the water taking robot 7. When manually rotating the crossbar 4, the rotating member 6 plays a key supporting and guiding role. It allows the crossbar 4 to rotate left and right while maintaining connection with the winch rope 31 without being restricted or interfered by the winch rope 31.

[0060] Referring to Figure 7 In this embodiment, the top of the rotating member 6 has a circular ring for hanging the fixed hook at the end of the winch rope 31. The rotating member 6 has a bearing inside, and the crossbar 4 is sleeved on the outer ring position of the bearing, so that the crossbar 4 can be manually pushed left and right, and the crossbar 4 rotates around the rotating member 6.

[0061] Referring to Figure 1 , Figure 2 and Figure 4 In this embodiment, the crossbar 4 extends beyond the two sides of the hanger 1. Figure 1 , Figure 2 and Figure 4It is shown that the crossbar 4 not only spans the width of the hanger 1, but also extends outward a distance at both ends. In practical applications, the hanger 1 is relatively narrow, and the crossbar 4 is relatively long. This design enables the crossbar 4 to provide a wider support surface, which facilitates the connection between the water collection robot 7 and the hanger rope assembly 5 without contacting the shell of the water collection robot 7.

[0062] The embodiment also provides a drainage vehicle, which includes a chassis, a winch device and the water collection robot 7. The winch device is arranged on the chassis, and the chassis can provide the water collection robot 7 with power required for operation, such as hydraulic energy or electric energy. The winch device is the winch device described in any of the above embodiments, and the water collection robot 7 is hoisted by the winch device. By integrating the winch device and the water collection robot 7, the drainage vehicle can achieve rapid and accurate identification and drainage operation on narrow and difficult-to-reach targets.

[0063] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, the patent protection scope of the present application should not be limited.
