Description

Technical Field

[0001] The utility model relates to the technical field of electric winch brakes, in particular to a brake control mechanism for an electric winch used in marine vessels. Background Art

[0002] An electric winch refers to a light and small lifting device that winds a wire rope or chain around a drum to lift or tow heavy objects, also known as a winch. A winch can vertically lift, horizontally or obliquely tow heavy objects. Winches are divided into three types: manual winches, electric winches, and hydraulic winches. The electric winch is the main one. It can be used alone or as a component in machinery such as lifting, road construction, and mine hoisting. It is widely used because of its simple operation, large rope winding capacity, and convenient relocation. It is mainly used for the lifting or horizontal towing of materials in construction, water conservancy projects, forestry, mines, docks, etc. At present, when a marine vessel is in use, an electric winch is needed to wind up the anchor chain or rope. The brakes of traditional electric winches are relatively simple, and it is inconvenient to replace the worn brake blocks. Moreover, due to the single braking position, the brake is prone to slipping problems. For this reason, we propose a brake control mechanism for an electric winch used in marine vessels. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a brake control mechanism for an electric winch used in marine vessels. The motor drives the screw to rotate to adjust the height of the brake block, which cooperates with the brake disc to brake the drum, and it is also convenient for replacement. At the same time, the hydraulic rod drives the pressing plate to press down to fix the anchor chain or rope, so as to prevent slipping problems during braking, and the problems in the background art can be effectively solved.

[0004] To achieve the above object, the utility model provides the following technical solution: A brake control mechanism for an electric winch used in marine vessels, including a chassis and a brake disc;

[0005] Chassis: Brackets are fixed on both the left and right sides. A drum is rotatably connected inside the two brackets. The left end of the drum is connected to the right end of a coupling. There are two brake discs, which are respectively installed on the left and right sides of the drum. An adjusting unit is provided on the side of the bracket. An installation block is inserted into the adjusting unit. The top of the installation block is connected to the bottom surface of the brake block. A fixing unit is provided on the front side of the chassis;

[0006] Among them, it further includes a controller, which is arranged on the left side of the chassis. The input end of the controller is electrically connected to the output end of an external power supply.

[0007] The coupling at the left end of the drum is connected to an external speed reducer to rotate it, thereby completing the winding and unwinding of the anchor chain or rope. When the brake block contacts the brake disc, it can brake the drum.

[0008] Further, the adjusting unit includes a fixed seat, a carriage, a screw rod, a connecting plate, a motor and a fixing bolt. The connecting plate is fixed to the side surface of the bracket. A motor is fixed to the bottom surface of the connecting plate. The output shaft of the motor is connected to the bottom end of the screw rod. The carriage is slidably connected to the chute on the side surface of the bracket. A fixed seat is fixed to the inner end of the carriage. The mounting groove on the top surface of the fixed seat is correspondingly inserted with the mounting block. The fixing bolt is threadedly connected to the threaded hole on the front side surface of the fixed seat. The input end of the motor is electrically connected to the output end of the controller. The brake block can be installed on the top surface of the fixed seat by using the fixing bolt. Starting the motor to drive the screw rod to rotate can adjust the height of the brake block, so that when it contacts the brake disc, it can brake the drum.

[0009] Further, the fixing unit includes a pressing plate, a placing rack, a hydraulic rod, a bolt and a supporting frame. Supporting frames are fixed to both sides of the bottom surface of the placing rack. The supporting frames are correspondingly inserted into the grooves on the front side surface of the bottom frame.

Hydraulic rods are installed on both the left and right side surfaces of the placing rack. The top end of the hydraulic rod is connected to one side of the bottom surface of the pressing plate. The input end of the hydraulic rod is electrically connected to the output end of the controller. The supporting frame is installed and fixed by using the bolt. Starting the hydraulic rod to drive the pressing plate to press down can press and fix the anchor chain or rope, thereby improving the efficiency and effect of braking.

[0010] Further, the fixing unit further includes a clamping frame, a rubber pressing block and an arc seat. Clamping frames are fixed to both sides of the top surface of the rubber pressing block. The clamping frames are correspondingly clamped into the clamping grooves on the surface of the pressing plate. The arc seat is fixed to the bottom surface inside the placing rack. The clamping frames are clamped into the clamping grooves to install the rubber pressing block, thereby increasing the stability of the pressing and fixing of the anchor chain or rope. At the same time, the arc seat can prevent large abrasions and wear during the retraction and release of the anchor chain or rope.

[0011] Further, it further includes a protective shell, a T-shaped block and a retaining rod. A T-shaped block is fixed inside the protective shell. The T-shaped block is correspondingly clamped into the T-shaped groove on the surface of the bracket. The retaining rod is rotatably connected to the top end of the outer side surface of the bracket. The T-shaped block is inserted into the T-shaped groove to install the protective shell, and the protective shell is fixed by rotating the retaining rod, which can protect against the splashing slag during braking.

[0012] Further, it further includes a laser speed detector. The laser speed detector is fixed to the bottom end of the inner side surface of the bracket. The output end of the laser speed detector is electrically connected to the input end of the controller. The laser speed detector can detect the rotation speed of the drum, thereby automatically adjusting the position of the brake block.

Starting the hydraulic rod drives the pressing plate to press down to press and fix the anchor chain or rope, thereby improving the efficiency and effect of braking. The clamping frame is clamped into the clamping groove to install the rubber pressing block to increase the stability of the pressing and fixing of the anchor chain or rope. At the same time, the arc seat can prevent large abrasions and wear during the retraction and release of the anchor chain or rope. BRIEF DESCRIPTION OF THE DRAWINGS
