Description

Technical Field

[0001] The utility model relates to the technical field of automobile winches, in particular to an automatic mud-clearing automobile winch. Background Art

[0002] Automobile winches are usually used in special engineering rescue vehicles. They are generally used to drag larger equipment or vehicles in trapped scenarios by reeling in the steel cable. Alternatively, after the steel cable has completed the towing and rescue, the external steel cable can be slowly reeled in.

[0003] In actual use, existing automobile winches are mostly used in muddy scenes to drag and rescue equipment or vehicles that are stuck in the mud and cannot move. In this environment, the steel cable pulled outside the winch will be more or less adhered to impurities and sludge. After the rescue is completed, the steel cable with sludge impurities will bring the sludge impurities back into the winding structure during the winding process, resulting in the problem of reduced service life of the winding structure. Therefore, the existing automobile winch will automatically drive mud from the wound-up steel cable through the brush structure during winding. However, the mud driving effect and mud driving efficiency will have certain defects if the mud is only driven by the contact between the steel cable and the brush during winding. Therefore, technical personnel in this field provide an automatic mud cleaning automobile winch to solve the problems raised in the above background technology. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic mud-clearing automobile winch, comprising a mounting base, a fixing plate and a water-passing collar, wherein the upper end surface of the mounting base is fixedly connected to the fixing plate at the middle position of the front end, the upper end surface of the fixing plate is fixedly connected to the fixing frame at the positions of the two sides of the front end, the upper end of the fixing frame is fixedly connected to the water-passing collar, the upper end surface of the fixing plate is fixedly connected to the mounting plate at the rear end position, the front end of the mounting plate is fixedly connected to the second mud-driving ring at the position corresponding to the annular center of the water-passing collar, and the inner side of the water-passing collar A plurality of high-pressure spray guns are fixedly connected at equal intervals, and the plurality of high-pressure spray guns are all connected to the inner side of the water-passing collar. A booster pump is fixedly connected to one side of the upper end surface of the fixing plate and located at the position of the mounting plate and the fixing frame. The output and input ends of the booster pump are both connected with external water pipes. The side of the external water pipe away from the output end of the booster pump is connected with the input end of the water-passing collar. A winch protection box is fixedly connected to the upper end surface of the mounting base plate at the rear end, and a winding roller is rotatably connected to the interior of the winch protection box, and a steel cable is fixedly connected to one side of the roller body of the winding roller.

[0006] Furthermore, a hydraulic motor is fixedly connected to one end surface of the winch protection box, and the output end of the hydraulic motor rotates through the winch protection box and is fixedly connected to the winding roller. The connection relationship between the hydraulic motor and the output end of the hydraulic motor and the winding roller makes it convenient for the device to provide driving force for the winding of the winding roller through the hydraulic motor.

[0007] Furthermore, an end cover is fixedly connected to the upper end of the winch protection box, and a matching groove is provided at the upper position of the front end surface of the winch protection box. The end cover installed at the upper end of the winch protection box can protect the winding structure in the winch protection box.

[0008] Furthermore, both ends of the inner side of the second mud driving ring are chamfered, and the inner diameter of the second mud driving ring is 1-5mm larger than the outer diameter of the steel cable. The chamfered angle on the second mud driving ring and the design that the inner diameter is 1-5mm larger than the outer diameter of the steel cable can not only remove the mud impurities adhering to the steel cable through the second mud driving ring, but also avoid friction between the mud driving ring inlet and outlet surface and the outer side of the steel cable, which causes severe wear.

With the design of this structure, the threaded screw on the inner side of the fixed frame will drive the threaded sleeve mounted on the threaded screw to adjust its position under the operation of the synchronous motor, and the operation of the synchronous motor can provide power for the operation of this structure.

[0010] Furthermore, a brush mounting frame is fixedly connected to the inner side of the fixed frame at the rear end position by fixing bolts, and multiple hard brushes are fixedly connected to the inner side of the frame body of the brush mounting frame, and multiple hard brushes are frictionally matched with the steel cable. The design of this structure allows the steel cable to continuously rub against the hard brush on the inner side of the brush mounting frame during the winding process, and can clean out some impurities remaining on the steel cable after being flushed by a high-pressure water gun and passing through the first mud driving ring and the second mud driving ring. At the same time, the fixed bolt installation form also facilitates the regular replacement of the hard brushes on the brush mounting frame.

The chamfered angle on the first mud driving ring and the design that the inner diameter is 1-5mm larger than the outer diameter of the steel cable can not only remove the mud impurities adhering to the steel cable through the first mud driving ring, but also avoid friction between the mud driving ring entrance and exit surfaces and the outer side of the steel cable, resulting in severe wear.

[0012] Furthermore, the threaded sleeve is fixedly connected to a limit slider at the middle position of the upper and lower ends, and the inner upper and lower end surfaces of the fixed frame are provided with limit slide rails at positions corresponding to a pair of limit slide rails, and the limit slide rails and the limit slide rails are mutually limited and slidably matched.

[0014] The automobile winch of this design, through the designed water supply structure in the form of an external water source, cooperates with the set booster pump, water-passing ring and multiple high-pressure spray guns surrounding the inner side of the water-passing ring, to achieve strong and all-round high-pressure water flushing of the just-reeled steel cable, and cooperates with the two mud-driving rings with chamfered arc angles to remove most of the mud impurities adhering to the surface of the steel cable, and can also prevent the moving steel cable from driving the cleaned mud impurities into the brush cleaning section. The practicality of its structure makes the equipment, compared with the traditional brush mud cleaning winch, through full-angle high-pressure flushing combined with two ring structures, greatly improves the mud cleaning efficiency and mud cleaning quality of the steel cable, and greatly reduces the accumulation rate of mud impurities in the brush.

[0031] Working principle and use process of the utility model: When the device is actually used:

After two steps of mud driving and flushing, the steel cable 9 will be rubbed and cleaned by the hard brush 23 to remove the last small amount of sludge, impurities and water, and finally complete the automatic mud cleaning work during the winding of the steel cable. Its overall design greatly improves the cleaning efficiency and cleaning quality of sludge impurities.
