[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0024] like Figure 1-3As shown, the utility model provides a rake winch for a rake bucket loader, comprising a reduction box 2 and a support frame 4, the top of the support frame 4 is respectively fixedly connected with a first support ring 41 and a second support ring 42, and a movable mechanism 5 is installed above the support frame 4;

[0025] The movable mechanism 5 includes a first mounting plate 52 and a second mounting plate 56, a sliding rod 53 is fixedly connected between the first mounting plate 52 and the second mounting plate 56, a screw rod 54 is arranged on one side of the sliding rod 53, two ends of the screw rod 54 are rotatably connected to the first mounting plate 52 and the second mounting plate 56 respectively, a movable plate 542 is threadedly connected to the surface of the screw rod 54, the movable plate 542 is slidably connected to the sliding rod 53, a guide assembly 55 is installed on the upper end of the movable plate 542, a sliding frame 57 is fixedly connected to the bottom of the second mounting plate 56, the sliding frame 57 is slidably connected to the second mounting plate 56, and a locking rod 572 is threadedly connected to the bottom end of the sliding frame 57, one end of the locking rod 572 passes through the sliding frame 57, and the locking rod 572 abuts against the second supporting ring 42, a sliding groove 421 is opened on the side wall of the second supporting ring 42, a guide block 571 is slidably connected inside the sliding groove 421, and the guide block 571 is fixedly connected to the sliding frame 57. A rotating frame 51 is fixedly connected to the bottom end of the first mounting plate 52 , and the rotating frame 51 is rotatably connected to the first supporting frame 4 .

[0026] The specific configuration and function of this embodiment are described in detail below. When the drive motor 1 is started, it transmits power through the reduction box 2, and then drives the winch body 3 to start working and perform the task of retracting and releasing the wire rope. In this process, in order to ensure that the wire rope can move smoothly and safely, a guide sleeve 551 is specially designed. Passing the wire rope through the guide sleeve 551 not only provides the necessary guidance and ensures that the wire rope moves along the predetermined path, but also significantly reduces the friction between the wire rope and other components.

[0027] In addition, the rotating frame 51 is designed to rotate freely on the surface of the first support frame 4, allowing the operator to adjust the direction of the guide sleeve 551 as needed to adapt to different working scenarios. The sliding frame 57 can slide on the surface of the second support frame 4, further enhancing the flexibility of the guide sleeve 551. During the rotation or sliding process, the guide block 571 is always located inside the sliding groove 421, which not only ensures the stability of the movement of the sliding frame 57, but also prevents equipment failures caused by unexpected situations.

[0028] After being adjusted to a suitable angle, the locking rod 572 can lock the position of the sliding frame 57 by simply rotating, thereby ensuring that the guide sleeve 551 maintains a stable guiding angle in subsequent work. Example

[0029] like Figure 1 and Figure 4As shown, the guide assembly 55 includes a guide sleeve 551 and a rotating rod 552, one end of the rotating rod 552 is fixedly connected to the guide sleeve 551, the rotating rod 552 is rotatably connected to the moving block, and the outer surface of one end of the rotating rod 552 is fixedly connected to the second bevel gear 554. The top side wall of the moving plate 542 is rotatably connected to a knob 555, and the outer surface of the knob 555 is fixedly connected to a first bevel gear 553. The first bevel gear 553 is meshedly connected to the second bevel gear 554, and one end of the screw rod 54 is fixedly connected to the rocker 541. A driving motor 1 is installed on the top of the reduction box 2, and the output end of the driving motor 1 is fixedly connected to the input end of the reduction box 2. The output end of the reduction box 2 is fixedly connected to the winch body 3, and the bottom of the reduction box 2 is fixedly connected to the support frame 4.

[0030] The effect achieved by the whole embodiment is that the rotation of the screw rod 54 can be easily controlled by using the rocker 541. When the screw rod 54 rotates, it interacts with the thread on the moving plate 542, thereby driving the moving plate 542 to move along the axis of the screw rod 54. This design allows the operator to easily adjust the front and rear positions of the guide sleeve 551 to meet different work requirements.

[0031] At the same time, in order to ensure the stability of the moving plate 542 during the movement, in addition to the support of the screw rod 54, a slide bar 53 is also provided under the moving plate 542. While the moving plate 542 slides on the surface of the screw rod 54, it also slides smoothly on the surface of the slide bar 53. This dual support structure not only improves the stability of the moving plate 542, but also effectively reduces equipment failures caused by vibration or impact.

[0032] In addition, the direction of the guide sleeve 551 can also be adjusted by a simple mechanical mechanism. When the operator turns the knob 555, it drives the first bevel gear 553 to rotate. Since the first bevel gear 553 is in meshing with the second bevel gear 554, the rotation of the first bevel gear 553 drives the second bevel gear 554 and the rotating rod 552 connected thereto to rotate. This design allows the operator to change the direction of the guide sleeve 551 without moving it, thereby achieving precise guidance of the wire rope.

[0033] The use method and working principle of the device: When the driving motor 1 is started, the winch body 3 is driven by the reduction box 2 to retract and release the wire rope. At this time, the wire rope can be passed through the guide sleeve 551, which can not only provide guidance for the wire rope, but also effectively prevent the wire rope from rubbing against other objects.

[0034] The rotating frame 51 is allowed to rotate freely on the surface of the first support frame 4, while the sliding frame 57 can slide smoothly on the surface of the second support frame 4. This design allows the angle of the guide sleeve 551 to be flexibly adjusted. During the adjustment process, the guide block 571 always slides in the sliding groove 421, ensuring the stability of the rotation of the sliding frame 57. The rotation of the locking rod 572 can abut against the second support frame 4, thereby locking the position of the sliding frame 57 and further fixing the guide angle of the guide sleeve 551.

[0035] In addition, the screw rod 54 can be easily driven to rotate by the rocker 541. The rotation of the screw rod 54 controls the movement of the moving plate 542, thereby changing the position of the guide sleeve 551. At the same time, the rotation of the knob 555 drives the first bevel gear 553 to rotate, and the meshing action with the second bevel gear 554 causes the rotating rod 552 to rotate, thereby adjusting the direction of the guide sleeve 551.

[0036] When the moving plate 542 slides on the surface of the screw rod 54, it also slides on the surface of the sliding rod 53 at the same time. This double sliding structure greatly enhances the stability of the moving plate 542 when sliding.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
