Description

Technical Field

[0001] The present application relates to the technical field of winding equipment, and in particular to a dual-motor driven hydraulic winch. Background Art

[0002] Traditional hydraulic winches are generally driven by a motor and a reducer to directly rotate the drum. The hydraulic motor and the drum are coaxial, and the reducer is directly inserted into the drum. There is a support bearing on the right side of the winch, and the structure is simple.

[0003] Traditional hydraulic winches use a motor reducer to drive the drum to rotate. If the winch power is relatively large, it often requires a large motor reducer to drive it, which will inevitably cause the winch size to become larger and the cost to increase. In addition, as the motor displacement increases, the rated speed will become slower. If a motor drive is used, the maximum speed of the winch will be limited. At the same time, it is also difficult to select a high-power motor and reducer. Summary of the invention

[0004] The present application mainly solves the problems of difficulty in selecting the reducer of the winch motor driven by a traditional single motor, the rated speed of the high-power winch cannot meet the user's needs, and the large size and high cost.

[0005] To achieve the above objectives, the present application provides a dual-motor driven hydraulic winch: comprising a base, a pair of frames fixedly connected to the base, the two frames being rotatably connected to a drum assembly, the end of the drum assembly being fixedly connected to a coaxial large gear, a plurality of hydraulic motors are arranged on the frame near the large gear, the output end of each of the hydraulic motors is fixedly connected to a small gear, and a plurality of the small gears are meshed with the large gear, and the number of the hydraulic motor configurations is variable, thereby providing different rated powers to the winch.

[0006] Preferably, the reel assembly includes a main shaft, a roller is fixedly connected to the outside of the main shaft, both ends of the roller have retaining rings, and the large gear is fixedly connected to one end of the retaining ring facing away from the roller, which is easier to link with the driving mechanism.

[0007] As a preferred embodiment, the two frames on the base are respectively a first frame and a second frame, the first frame is closer to the large gear, the hydraulic motor is fixedly connected to the first frame, and the second frame is provided with a latch suitable for limiting the movement of the reel assembly relative to the second frame to achieve a locking function.

[0008] As a preference, a pin hole is provided on the retaining ring away from the large gear, and the latch comprises a pin column suitable for passing through the second frame and being engaged with the pin hole to facilitate locking and releasing actions.

[0009] Preferably, one end of the pin is fixedly connected to a handle via a limiting ring, and the end of the handle is fixedly connected to a force-applying ball, so that the grip is more comfortable during plugging and unplugging operations.

[0010] As a preference, both ends of the main shaft are connected to the first frame and the second frame respectively through bearings, so as to improve the stability of the main shaft rotation.

[0011] Preferably, shaft support rings are fixedly connected to the upper ends of the first frame and the second frame, and a shaft cover ring is fixedly connected to the top of each shaft support ring. Both the shaft support ring and the shaft cover ring are semicircular rings suitable for being clamped on the outer side of the bearing shell to inhibit the movement of the bearing shell.

[0012] As a preference, two hydraulic motors are provided, and the reel assembly and the large gear are both located between the first frame and the second frame, so that when the reel assembly rotates, the impact on the external connection will be smaller.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] (1) The winch is driven by multiple motors instead of a single motor, and the power is split. As the actual power demand increases, the number of hydraulic motors can be increased accordingly. It is not limited to two motors, but can be driven by two or more motors at the same time, avoiding the problem of matching hydraulic motors and reducers, making it easier to meet customer needs;

[0015] (2) The motor of this design is not limited to being installed on the same side, but can be installed on both sides. Therefore, the number of hydraulic motors that can be configured can be very large. The rated power upper limit of the winch is much higher than that of high-power, large-sized motors and reducers, and it can handle a wider range of work. There is no need to use high-power, large-sized motors and reducers, which effectively reduces the configuration cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] like Figure 1-4The dual-motor driven hydraulic winch shown in the figure comprises a fixedly arranged base 1, a pair of frames are fixedly connected to the base 1, namely a first frame 3 and a second frame 4, the two frames are connected to a reel assembly 5 for rotation together, the specific structure of the reel assembly 5 comprises a main shaft 501, the two ends of the main shaft 501 are respectively connected to the first frame 3 and the second frame 4 through bearings 502, for the convenience of disassembly and assembly, the upper ends of the first frame 3 and the second frame 4 are fixedly connected with shaft support rings 301, and each shaft support ring 301 A shaft cover ring 302 is fixedly connected to the top, and the two are fixedly connected by bolts and other connecting parts. Both the shaft support ring 301 and the shaft cover ring 302 are semicircular rings, which can be stuck in the outer side of the bearing shell 502. Under normal circumstances, the two ends of the bearing shell 502 will protrude from the end face of the shaft support ring 301 or the shaft cover ring 302, and expand outward along the diameter direction to form a flange, which is just stuck in the end face of the shaft support ring 301 or the shaft cover ring 302, which can effectively limit the circumferential movement of the bearing shell 502, thereby ensuring the stability of the main shaft 501.

[0026] A roller 503 is fixedly connected to the outside of the main shaft 501. The outer side surface of the roller 503 is usually a cylindrical surface, which is the place where the material is rolled up. Both ends of the roller 503 are provided with a retaining ring 504, which is used to prevent the rolled material from exceeding the two ends of the roller 503. The end of the reel assembly 5 is fixedly connected to a large gear 6, which is coaxial with the reel assembly 5. The large gear 6 is fixedly connected to one end of the retaining ring 504 facing away from the roller 503 and facing the frame. The reel assembly 5 and the large gear 6 are both located between the first frame 3 and the second frame 4, so that the moving parts have less interference with the external connection.

[0027] A plurality of hydraulic motors 2 are arranged on the frame near the large gear 6. The number of hydraulic motors 2 can be changed according to the actual power demand, and two or more can be arranged. In the attached figure of this embodiment, two hydraulic motors 2 are arranged as a distance. Because the first frame 3 is closer to the large gear 6, the hydraulic motor 2 needs to be fixedly connected to the first frame 3 or the second frame 4. Two large gears 6 can also be arranged at the same time. Because the number of hydraulic motors 2 is large, the single-sided installation may be crowded. The output end of each hydraulic motor 2 is fixedly connected to a small gear 7, and several small gears 7 are meshed with the large gear 6, and together drive the drum assembly 5 to rotate through the large gear 6. Because the number of small gears 7 can be changed with the number of hydraulic motors 2, the entire winch has multiple levels of power.

[0028] A latch 8 is provided on the second frame 4 for limiting the movement of the reel assembly 5 relative to the second frame 4, thereby locking the reel and the frame; a pin hole 505 is provided on the retaining ring 504 away from the large gear 6; the latch 8 includes a pin column 801, which just passes through the second frame 4 and is engaged with the pin hole 505, thereby realizing the locking function; one end of the pin column 801 is fixedly connected to a handle 803 through a limiting ring 802; the limiting ring 802 is used to limit the maximum insertion depth of the pin column 801; a force ball 804 is fixedly connected to the end of the handle 803; compared with the handle 803, the force ball 804 is more rounded and smooth, has a larger diameter, is easier to disperse the force, and is more comfortable to hold.

[0029] Working principle: The winch is driven by two or more hydraulic motors 2. The small gear 7 at the output end of the hydraulic motor 2 can simultaneously drive the large gear 6 installed on the drum, thereby driving the drum to rotate. The drum is connected to the main shaft 501. Bearings 502 are provided at both ends of the main shaft 501 and supported in the frame to improve the stability of the main shaft 501 during rotation. A latch 8 is also provided on the right side of the winch, which can lock the drum and the frame after shutdown, thereby avoiding unnecessary shaking of the drum assembly 5 during transportation.

[0030] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
