Description

Technical Field

[0002] A winch is a device used to lift or pull heavy objects. It is usually composed of a motor, gears, a drum, wire ropes, chains, control systems, and other parts. It is widely used in construction engineering, mining, shipping, logistics, and other industries that require lifting and handling. The winch can be fixed or portable and can be configured on construction machinery such as cranes, tower cranes, and excavators. The basic working principle of the winch is to use the rotation of gears and drums to wind or unwind wire ropes or chains to achieve vertical or horizontal movement of objects. The motor provides power, reduces the speed through the reducer and increases the output torque, thereby driving the drum to rotate. The wire rope or chain is wrapped around the drum, one end is connected to the load, and the other end has an appropriate tension device. The main features and technical parameters of the winch include the maximum lifting capacity, the maximum load that the winch can lift, the lifting height, the maximum vertical distance that the wire rope or chain can lift, the lifting speed, the speed at which the object is lifted, the motor power, the power of the motor that drives the winch, the control method, the winch can be manually controlled, remotely controlled or automatically controlled, the rated voltage, the voltage required for the normal operation of the equipment, and the safety operating procedures must be strictly followed when using the winch to prevent accidents such as overloading, improper operation, and insufficient maintenance. Regular inspection and maintenance are also essential to ensure the safe operation of the winch. When choosing a winch, the appropriate model and specifications should be selected according to the operating requirements and the operating environment.

[0003] Therefore, the winch is very complicated in the production and manufacturing process, with many steps, and requires repeated testing and verification.

The slope rail 1 20 and the slope rail 2 21 are matched with the traction drive disk 19, and the traction drive disk 19 is connected to the load box 2 18. When the load box 2 18 is dragged and moved, the traction drive disk 19 moves accordingly, and the limit test can be carried out safely. When the steel rope 2 17 breaks during the limit test, the load box 2 18 will slide downward along the test slope 14 together with the traction drive disk 19, and will not tilt and cause danger.

[0026] A horizontal test track 22 is fixedly connected to the right end of the base plate 1, and a horizontal guide rail 23 is connected to the top of the horizontal test track 22 by bolts.

[0029] The top of the inner wall of the load box 12 and the bottom of the inner wall of the load box 12 are both provided with an inner cavity 32, the front end of the inner cavity 32 is provided with a suction pump 33, the bottom of the inner wall of the inner cavity 32 is welded with five anti-sway baffles 34 and are evenly spaced. The load box 12 itself has the weight of metal parts. In order to increase the weight and perform the limit weight test, the weight of the load box 12 is changed by inputting and discharging water. When there is no water in the two inner cavities 32, the load box 12 only has the weight of its own metal parts and the outer shell. When the suction pump 33 is running, water can be drawn in by connecting to an external pipeline and poured into the inner cavity 32. Increasing or filling the water source can increase the weight and perform the limit weight test.

[0030] The top of the inner wall of the load box 18 and the bottom of the inner wall of the load box 18 are both provided with two inner cavities 35, the front end of the two inner cavities 35 are both provided with suction pumps 36, and the bottom of the inner wall of the two inner cavities 35 are both welded with five anti-sway baffles 37 and are evenly spaced and distributed. The load box 18 itself has the weight of metal parts. In order to increase the weight and perform the limit weight test, the weight of the load box 18 is changed by inputting and discharging water. When there is no water in the two inner cavities 35, the load box 18 only has the weight of its own metal parts and the outer shell. When the suction pump 36 is running, water can be drawn in by connecting to an external pipeline and poured into the two inner cavities 35. Increasing or filling the water source can increase the weight and perform the limit weight test.

[0031] The inner wall of the load box three 24 is provided with four three-box inner cavities 38, and the right side of the three-box inner cavities 38 is provided with a suction pump three 39. The inner wall of the three-box inner cavities 38 is welded with three anti-sway baffles three 40 and they are evenly spaced. The load box three 24 itself has the weight of metal parts. In order to increase the weight and perform the limit weight test, the weight of the load box three 24 is changed by inputting and discharging water. When there is no water inside the four three-box inner cavities 38, the load box three 24 only has the weight of its own metal parts and outer shell. When the suction pump three 39 is running, it can draw water into the three-box inner cavities 38 by connecting to the external pipeline. Increasing or filling the water source can increase the weight and perform the limit weight test.

[0032] Working principle: The test pit 3 is equipped with a pit bottom protection seat 4, which can safely carry out limit tests. When the steel rope 11 breaks during the limit test, the load box 12 will fall to the pit bottom protection seat 4 area and will be unloaded by the multi-level buffer pit 5 filled with fillers. The fillers are sand and gravel layers and hard synthetic thick rubber pads. The support frame 16 and the support frame 27 are deployed upright on the left and right to maintain the stability of the vertical height of the winch deployment and the vertical lifting support effect. When the winch 9 deployed by the mounting seat 8 is running, the steel rope 11 drives the load box 12 to realize the test of vertical lifting dynamics. The rope delivery port 10 is convenient for the up and down passage of the steel rope 11. The elevated seat 13 can provide a high-position installation area, and is equipped with a test slope 14 to form a slope inclined traction route. The bottom of the slope stabilizing frame 15 relies on the base plate 1 to form a stable support for the test slope 14, and the base plate 22 can provide stable support for the front end of the test slope 14. When the winch 216 deployed by the elevated seat 13 is running, the steel rope 217 drives the load box 218 to realize the test slope tilting and dragging dynamics. When the test slope is tilted and dragged, a follow-up support component needs to be deployed at the bottom of the load box 21. Therefore, the test slope 14 is deployed with a slope slide rail 120 and a slope slide rail 21. The slope slide rail 120 and the slope slide rail 21 are matched with a dragging drive disk 19. The dragging drive disk 19 is connected to the load box 218. When the load box 218 is dragged and moved, the dragging drive disk 19 moves accordingly, and the limit test can be carried out safely. When the steel rope 217 is in the limit test, the limit test can be carried out safely. When the test breaks, the load box 2 18 will slide down along the test slope 14 together with the traction drive plate 19, and will not sway to cause danger. The horizontal test track 22 is matched with the horizontal guide rail 23, and then connected to the load box 3 24, so as to form a horizontal moving load test route. When the winch 3 26 deployed by the loading frame 25 is running, the steel rope 3 27 drives the load box 3 24 to realize the horizontal moving load test dynamic. When the limit test is carried out in the test slope 14 area, when the steel rope 2 17 breaks, the test protection box 1 28 can play the role of overall external covering protection, which can prevent the broken steel rope from splashing and other dangerous accidents. When the limit test is carried out in the horizontal test track 22 area, when the steel rope 3 27 breaks, the test protection box 2 29 can play the role of overall external covering protection, which can prevent the break. In order to prevent dangerous accidents such as cracked steel rope splashing, multiple protective plates 1 30 and protective plates 2 31 deployed in multiple places can further play a role of shielding and protection, and provide safety protection during extreme testing. Load box 1 12, load box 2 18 and load box 3 24 have their own metal parts weight. In order to increase the weight and conduct extreme weight testing, the weight of multiple load boxes is changed by inputting and discharging water. When there is no moisture in the two openings 32 in the first box, load box 12 only has its own metal parts and shell weight. The suction pump 1 33 can be operated to draw water into the opening 32 in the first box by connecting the external pipeline. When there is no moisture in the opening 35 in the second box, load box 2 18 only has its own metal parts and shell weight.When the suction pump 2 36 is running, water can be sucked in through the external pipeline and poured into the second box inner cavity 35. When there is no water inside the four third box inner cavities 38, the load box 3 24 only has its own metal parts and shell weight. When the suction pump 3 39 is running, water can be sucked in through the external pipeline and poured into the third box inner cavity 38. Increasing or filling the water source can perform the weight increase and limit weight test.
