Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anchor winch equipment, and particularly relates to a hydraulic anchor winch brake force test bracket and a use method. BACKGROUND

[0002] As a key equipment of a ship, the brake performance of a hydraulic anchor winch is directly related to the safety of the ship when it is moored, so the brake force test before delivery is a core link to ensure the safety of the equipment in use. In the brake force test, a driving assembly (such as a cylinder) needs to be used to apply a driving force to the rotating wheel of the anchor winch to judge the braking effect of the brake assembly, and the driving assembly needs to rely on a special bracket or base to realize support, positioning and height adaptation, so the rationality of the base structure directly affects the efficiency, stability and universality of the test.

[0003] A variety of support devices for brake force test have appeared in the prior art, such as a patent with the patent name of "a base for winch brake force test and winch brake force test device" and the patent number of CN215893875U. The base disclosed in the patent comprises a base body, a handle, a walking mechanism and a limiting assembly: the base body is composed of a bottom plate, a cover plate and a pipeline assembly, the pipeline assembly is connected to the bottom plate and the cover plate at both ends, and the area of the bottom plate and the cover plate is larger than the area of the end face of the pipeline assembly to ensure the stability of the support; the handle is connected to the side face of the pipeline assembly for convenient carrying; the walking mechanism is movably connected to the bottom plate through a second fastener and can be switched between a supporting position and a storage position; the limiting assembly is arranged on the top face of the cover plate to limit the horizontal displacement of the driving assembly; and the base is fixed to a working platform through a third fastener to further improve the stability.

[0004] However, the base of the above-mentioned prior art still has many defects that are difficult to overcome in actual application scenarios, which makes it unable to completely meet the efficient, accurate and universal test requirements. The specific problems are as follows:

[0005] 1. The switching operation of the walking mechanism is complicated: the walking mechanism in the patent needs to be manually disassembled through the second fastener to realize the switching of the support / storage state of the walking wheel —— the fastener needs to be loosened, the support angle needs to be adjusted, and then the fastener needs to be locked again. The base itself is heavy, and when adjusting the walking mechanism, one person needs to lift one side of the base to keep it in the air, and the other person needs to adjust the support frame. Not only is the operation inconvenient, but also it wastes human resources and is easy to injure workers, which has safety hazards.

[0006] 2. The fixed adaptation of the driving assembly is poor: the limiting assembly relies on screws or clamps to realize the horizontal fixation of the driving assembly. If the size and shape of the driving assembly change, the screw spacing needs to be adjusted or the clamp needs to be replaced, which has poor adaptability. During the fixation process, the screws need to be tightened one by one and the position needs to be calibrated, and during the disassembly, the screws also need to be loosened step by step. The overall test preparation time is long and the operation efficiency is low.

[0007] 3. The base is fixed complex: the base of the patent is fixed with the working platform through the third fastener, i.e. the screw fastener, either needs to prepare additional working platform, or needs to punch bolt hole on the deck, not only the operation is inconvenient, but also will damage the deck.

[0008] Therefore, it is necessary to provide a hydraulic anchor winch brake force test bracket and method of using to solve the above technical problems. SUMMARY

[0018] Preferably, at least two lifting lugs are fixedly connected to the outer peripheral wall of the bracket body, and the lifting lugs are used for cooperating with the lifting hooks of the crane to realize the lifting of the bracket body.

[0019] A method for using a hydraulic anchor winch braking force testing bracket includes the following steps:

[0020] Step 1, Pre-test preparation: Use a crane with lifting lugs to lift the main body of the bracket to the designated area on the deck, and transfer the hydraulic cylinder, pressure hose, pressure gauge and hand pump to the anchor winch to be tested; use bolts to fix the adapter plate to the pre-set installation position of the baffle of the anchor winch drum;

[0021] Step 2: Switch the bracket body to the moving mode: With the knob side as the left side of the bracket body, the end with the first drive bevel gear as the rear end of the bracket body, and the end with the second drive bevel gear as the front end of the bracket body; rotate the knob counterclockwise, driving the output bevel gear to rotate counterclockwise synchronously through the output shaft, and the first and second drive bevel gears meshing with the output bevel gear rotate synchronously in the opposite direction; viewed from the front to the rear, the first drive shaft rotates counterclockwise under the drive of the first drive bevel gear, and drives the first support shaft to rotate counterclockwise synchronously through the first transmission component; the second drive shaft rotates clockwise under the drive of the second drive bevel gear, and drives the second support shaft to rotate clockwise synchronously through the second transmission component; the two wheel supports on the left side rotate counterclockwise with the first support shaft, and the two wheel supports on the right side rotate clockwise with the second support shaft, until all four casters are in contact with and supported by the deck, and the bottom surface of the bracket body is completely separated from the deck;

[0022] Step 3, Initial positioning of the bracket body: Move the bracket body to the position directly below the hinged side of the adapter plate and the output end of the hydraulic cylinder using the casters; place the hydraulic cylinder in the center positioning area on the top surface of the bracket body, and hinge one side of the adapter plate to the output end of the hydraulic cylinder; connect the hand pump to the cylinder body of the hydraulic cylinder through the pressure hose, and install a pressure gauge at the preset interface of the pressure hose to complete the initial assembly and positioning of the test equipment;

[0023] Step 4: Final positioning of the bracket body and switching to the storage support mode: Fine-tune the horizontal position of the bracket body until the hinge point of the adapter plate and the output end of the hydraulic cylinder, the center line of the hydraulic cylinder, and the center line of the bracket body are collinear; rotate the knob clockwise to drive the output bevel gear to rotate clockwise synchronously through the output shaft, while the first transmission bevel gear and the second transmission bevel gear rotate counterclockwise synchronously; viewed from the front to the rear, the first transmission shaft rotates clockwise and drives the first support shaft to rotate clockwise synchronously through the first transmission component, while the second transmission shaft rotates counterclockwise and drives the second support shaft to rotate counterclockwise synchronously through the second transmission component; the left wheel bracket rotates clockwise with the first support shaft, and the right wheel bracket rotates counterclockwise with the second support shaft until the caster wheels are completely separated from the deck, and the bottom surface of the bracket body is in contact with the deck for support. At this time, the second magnet at the bottom of the bracket body is attracted and fixed to the deck;

[0024] Synchronously, when the first drive shaft rotates clockwise, the left lever arm assembly applies an upward driving force to the bottom end of the left guide post through the linkage of the first and second lever arms; when the second drive shaft rotates counterclockwise, the right lever arm assembly applies an upward driving force to the bottom end of the right guide post through the linkage of the first and second lever arms; the two guide posts slide vertically upward along the guide sleeve, the first magnet at the top of the guide post is in contact with the top surface inside the bracket body, and the steel cylinder body of the hydraulic cylinder is attracted and fixed to the top surface of the bracket body under the magnetic force of the first magnet;

[0027] Step 7, Lifting and Storage of the Bracket Body: Push the bracket body to the crane operating area, fix it to the crane hook through the lifting lugs, start the crane to lift the bracket body off the deck and transfer it to the designated storage location.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. Efficient and safe switching of the walking mechanism: Through the linkage design of knob + transmission bevel gear set + transmission component, rotating the knob can drive the universal wheels to unfold or retract without disassembling fasteners; a single person can complete the switching operation, avoiding the cumbersome process of "requiring multiple people to cooperate" in the existing technology, eliminating the risk of falling injury, and improving the safety and efficiency of operation.

[0030] 2. The drive components are easy to install and disassemble and have strong adaptability: The steel cylinder body is attracted by the first magnet, eliminating the need for rigid fasteners such as screws and clamps, and adapting to cylinders of different sizes and shapes; the adsorption-type fixation eliminates the need for individual calibration and tightening / loosening of parts, making the installation and disassembly process quick and solving the problems of "poor adaptability and long test preparation time" in existing technologies.

[0031] 3. The base is easy to fix and does not damage the working environment: The bottom of the bracket is fixed to the deck by adhering to the second magnet, which eliminates the need for an additional working platform and drilling holes in the deck to install fasteners, thus avoiding the defects of existing technologies that are "complex to fix and damage the deck structure".

[0032] 4. Improved overall portability and operational flexibility: The preliminary and final positioning processes are simplified, and the cylinder and adapter plate can be precisely aligned by adjusting the bracket with the universal wheels, further improving testing efficiency.

A method of using the hydraulic anchor winch braking force test bracket according to any one of claims 1-4, characterized in that, Includes the following steps: Step 1, Pre-test preparation: Use a crane with lifting lugs to lift the main body of the bracket to the designated area on the deck, and transfer the hydraulic cylinder, pressure hose, pressure gauge and hand pump to the anchor winch to be tested; use bolts to fix the adapter plate to the pre-set installation position of the baffle of the anchor winch drum; Step 2: Switch the bracket body to the moving mode: With the knob side as the left side of the bracket body, the end with the first drive bevel gear as the rear end of the bracket body, and the end with the second drive bevel gear as the front end of the bracket body; rotate the knob counterclockwise, driving the output bevel gear to rotate counterclockwise synchronously through the output shaft, and the first and second drive bevel gears meshing with the output bevel gear rotate synchronously in the opposite direction; viewed from the front to the rear, the first drive shaft rotates counterclockwise under the drive of the first drive bevel gear, and drives the first support shaft to rotate counterclockwise synchronously through the first transmission component; the second drive shaft rotates clockwise under the drive of the second drive bevel gear, and drives the second support shaft to rotate clockwise synchronously through the second transmission component; the two wheel supports on the left side rotate counterclockwise with the first support shaft, and the two wheel supports on the right side rotate clockwise with the second support shaft, until all four casters are in contact with and supported by the deck, and the bottom surface of the bracket body is completely separated from the deck; Step 3, Initial positioning of the bracket body: Move the bracket body to the position directly below the hinged side of the adapter plate and the output end of the hydraulic cylinder using the casters; place the hydraulic cylinder in the center positioning area on the top surface of the bracket body, and hinge one side of the adapter plate to the output end of the hydraulic cylinder; connect the hand pump to the cylinder body of the hydraulic cylinder through the pressure hose, and install a pressure gauge at the preset interface of the pressure hose to complete the initial assembly and positioning of the test equipment; Step 4: Final positioning of the bracket body and switching to the storage support mode: Fine-tune the horizontal position of the bracket body until the hinge point of the adapter plate and the output end of the hydraulic cylinder, the center line of the hydraulic cylinder and the center line of the bracket body are collinear; Rotating the knob clockwise drives the output bevel gear to rotate clockwise synchronously via the output shaft, while the first and second transmission bevel gears rotate counterclockwise synchronously. Viewed from the front to the rear, the first transmission shaft rotates clockwise and drives the first support shaft to rotate clockwise synchronously via the first transmission component, while the second transmission shaft rotates counterclockwise and drives the second support shaft to rotate counterclockwise synchronously via the second transmission component. The left wheel support rotates clockwise with the first support shaft, and the right wheel support rotates counterclockwise with the second support shaft until the caster wheels are completely separated from the deck, and the bottom surface of the bracket body is in contact with and supported by the deck. At this time, the second magnet at the bottom of the bracket body is attracted and fixed to the deck. Simultaneously, when the first drive shaft rotates clockwise, the left lever arm assembly applies an upward driving force to the bottom end of the left guide post through the linkage of the first lever arm and the second lever arm; When the second drive shaft rotates counterclockwise, the right lever arm assembly applies an upward driving force to the bottom of the right guide post through the linkage of the first and second lever arms; the two guide posts slide vertically upward along the guide sleeve, the first magnet at the top of the guide post is in contact with the top surface inside the bracket body, and the steel cylinder of the oil cylinder is attracted and fixed to the top surface of the bracket body under the magnetic force of the first magnet. Step 5: Complete the anchor winch braking force test; Start the anchor winch braking force test by adjusting the hydraulic cylinder output pressure through a hand pump and combining the pressure gauge reading to complete the braking force test. Step 6: Switch the bracket body to the moving mode again: Disconnect the hinge connection between the adapter plate and the output end of the hydraulic cylinder, repeat the operation of Step 2, rotate the knob counterclockwise until the caster wheel is in contact with the deck for support, and the bottom surface of the bracket body separates from the deck; at the same time, the guide column slides vertically downward along the guide sleeve, the first magnet separates from the top surface inside the bracket body, the hydraulic cylinder body is freed from the magnetic constraint, and the hydraulic cylinder, pressure hose, pressure gauge and hand pump are disassembled and stored in sequence; Step 7, Lifting and Storage of the Bracket Body: Push the bracket body to the crane operating area, fix it to the crane hook through the lifting lugs, start the crane to lift the bracket body off the deck and transfer it to the designated storage location.
