Abstract
Description
Technical Field
[0001] The present application relates to the technical field of winch cooling, and in particular to a cooling pipeline structure for a free-fall winch. Background Art
[0002] A winch is a lightweight lifting device that uses a drum-wound wire rope or chain to lift or pull heavy objects. It is widely used in construction, mining, docks, and other fields. Free-fall winches, due to their compact structure and ease of use, offer high efficiency and practical value in lifting and pulling heavy objects.
[0003] Currently, free-fall winches in related technology include a housing, a drum, a built-in speed reducer, a motor, and a free-fall brake. The drum is rotatably connected to the housing, and the built-in speed reducer is located within the drum. While compact, the built-in speed reducer for winches has poor heat dissipation. The built-in speed reducer includes a drive shaft, which rotates to drive the drum for hoisting. The motor is mounted on one end of the drive shaft via a motor flange, driving the shaft's rotation. The free-fall brake is mounted on the outer periphery of the drive shaft via a brake flange, braking the drive shaft with the free-fall brake.
[0004] However, during the operation of the winch, heat will be generated due to factors such as the mechanical movement of the reducer. Since the free fall winch usually adopts a built-in reducer design, such as Figure 1 As shown, the reducer has a compact structure inside the drum and does not have a large space for arranging the cooling structure. Therefore, the pipelines configured for the reducer are only used to calibrate the oil level and for ventilation. There is no cooling interface and cooling pipelines cannot be configured, which will affect the overall performance and service life of the equipment.

[0042] The following is combined with Figure 1 -Attached Figure 8The present application is further described in detail. In this embodiment, unless otherwise specified, the terms "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, and can be understood based on the specific circumstances.

Unless otherwise specified, orientation words such as "inside" and "outside" used in this application refer to the outlines of the corresponding components themselves.
[0044] like Figure 2 As shown, the present invention discloses a cooling pipeline structure for a free-fall winch (hereinafter referred to as the "cooling pipeline structure"). The cooling pipeline structure includes a first oil inlet pipeline 11, a first oil outlet pipeline 12, a measuring pipeline 2, and a vent assembly 3. This enables the free-fall winch to achieve effective cooling while maintaining a calibrated oil level and venting functions.
[0045] like Figure 2 、 Figure 3 and Figure 4 As shown, the free fall winch includes a reducer 100, a motor, and a brake. The motor is coupled to the reducer 100 via a motor flange 200, and the brake is coupled to the reducer 100 via a brake flange 300. The brake flange 300 is provided with a first through hole and a second through hole, both of which are connected to the cavity of the reducer 100.
[0046] A cooler is provided on one side of the reducer 100. The cooler can be of an existing structure. The lubricating oil is cooled in the cooler to form lubricating oil with a cooling effect, i.e., cooling oil. Providing a cooler on the outside of the reducer 100 can reduce the need to occupy the internal space of the reducer 100. The first end of the first oil inlet pipe 11 is connected to the first through hole, and the second end of the first oil inlet pipe 11 is connected to the oil outlet of the cooler. The first end of the first oil outlet pipe 12 is connected to the second through hole, and the second end of the first oil outlet pipe 12 is connected to the oil inlet of the cooler. Since the cooler is connected to the reducer 100 through the first oil inlet pipe 11 and the first oil outlet pipe 12, the length and extension direction of the first oil inlet pipe 11 and the first oil outlet pipe 12 are easy to adjust, so the cooler can be set at a suitable position as needed to meet the compact structure of the built-in reducer and the space limitation in the reel. The first oil inlet line 11 connects the oil outlet of the cooler to the first through-hole on the brake flange 300, allowing the lubricating oil cooled by the cooler to enter the cavity of the reducer 100 through the first through-hole, thereby cooling and lubricating the interior of the reducer 100. At the same time, the first oil outlet line 12 connects the second through-hole to the oil inlet of the cooler, allowing the lubricating oil passing through the reducer 100 to flow back to the cooler through the second through-hole for further cooling, forming a continuously circulating cooling pipeline structure.
[0047] like Figure 2 and Figure 5 As shown, the first through hole is provided above the second through hole, so that the lubricating oil enters from the upper part of the cavity of the reducer 100 and flows out through the lower part of the cavity of the reducer 100. The first end of the measuring line 2 is connected to the first oil outlet line 12, and the second end of the measuring line 2 is used to measure the oil level. Since the first oil outlet line 12 is located at the lower position of the cavity of the reducer 100, it helps to accurately obtain the oil level value in the cavity of the reducer 100. The measuring line 2 is connected to the first oil outlet line 12 and is designed with an oil level measurement function at its second end, so that the oil level condition in the reducer 100 can be monitored at any time, ensuring the reliable lubrication and reducing frictional heat, thereby helping to achieve cooling of the reducer 100.
[0048] Braking flange 300 defines a third through-hole that connects to the cavity of reducer 100. Ventilation assembly 3 connects to this third through-hole, allowing ventilation of the cavity of reducer 100. By connecting to the third through-hole on braking flange 300, ventilation assembly 3 ensures pressure balance inside and outside the cavity of reducer 100, allowing lubricating oil to flow smoothly, effectively cooling and maintaining internal components.
[0049] like Figure 2 and Figure 5As shown, optionally, the breathable component 3 includes a breathable pipeline 31, a liquid storage tank 32 and a breathable cap 33. The first end of the breathable pipeline 31 is connected to the third through hole, the liquid storage tank 32 is arranged at the second end of the breathable pipeline 31, and the breathable cap 33 is arranged at the end of the liquid storage tank 32 away from the breathable pipeline 31. The breathable component 3 can realize the breathability function of the cavity of the reducer 100, balance the pressure inside and outside the reducer 100, reduce the risk of oil seal damage and oil leakage, and ensure the reliability of operation. The liquid storage tank 32 can also collect lubricating oil that may overflow, thereby collecting oil leakage, reducing environmental pollution and maintenance costs. The heat inside the reducer 100 can be effectively dissipated through the breathable component 3. At the same time, the liquid storage tank 32 can collect condensed water, alleviate the problem of lubrication failure caused by condensed water flowing back into the reducer 100, and improve the heat dissipation efficiency and operational reliability of the cooling pipeline structure. The vent assembly 3 can utilize an existing structure; this cooling pipeline structure provides ventilation for the reducer 100 by adding a separate pipeline to accommodate the liquid reservoir 32 and vent cap 33. Optionally, a third through-hole is positioned above the second through-hole, allowing the vent assembly 3 to more effectively exhaust gas from the cavity of the reducer 100. This also reduces the risk of lubricating oil backflowing into the vent line 31 during non-operating conditions, improving the stability and reliability of the cooling pipeline structure.
[0050] like Figure 2 and Figure 5 As shown, the measuring line 2 can optionally be L-shaped, comprising a first section 21 and a second section 22. The L-shaped measuring line 2 helps save space and reduce interference with surrounding structures, allowing the measuring line 2 to be flexibly arranged within a limited space, facilitating connection to the first oil outlet line 12 and oil level measurement. The first section 21 and the second section 22 are arranged at an angle, with the first section 21 connecting to the lower ends of the first oil outlet line 12 and the second section 22, respectively. The second section 22 is arranged vertically. This vertical arrangement facilitates the insertion and reading of the oil dipstick 5, improving the accuracy and convenience of oil level measurement.
[0051] like Figure 2 and Figure 5As shown, optionally, the measuring pipeline 2 includes a flexible connection portion, and the first oil outlet pipeline 12 includes an oil outlet connection portion 121. One end of the oil outlet connection portion 121 is connected to the first oil outlet pipeline 12, the other end of the oil outlet connection portion 121 is connected to the first end of the flexible connection portion, and the second end of the flexible connection portion is connected to the first section 21, so that the axis of the first section 21 and the oil outlet connection portion 121 may not be on the same straight line. The flexible connection portion may be a flexible tubular structure so that the first section 21 and the oil outlet connection portion 121 may be staggered. The oil outlet connection portion 121 enables the measuring pipeline 2 to be connected to the cavity of the reducer 100 to achieve oil level measurement. The provision of the flexible connection portion enables the measuring pipeline 2 to adapt to changes in different working positions, thereby improving the installation adaptability and reliability of the measuring pipeline 2. When the free-fall winch is operating, mechanical vibrations may cause the relative positions of various components to shift. One end of the oil outlet connector 121 is securely connected to the first oil outlet pipeline 12, while the first end of the flexible connector is connected to the other end of the oil outlet connector 121. This helps maintain good sealing and stability even in vibrating environments. The second end of the flexible connector is connected to the first section 21 of the measuring pipeline 2, which not only helps measure oil level changes but also mitigates the effects of vibration to a certain extent, improving the reliability of the entire cooling pipeline structure.
[0052] Optionally, the flexible connection portion is made of rubber. Made of a highly elastic rubber material, the flexible connection portion can effectively absorb stress generated by vibration or thermal expansion and contraction of the measuring pipeline 2 during use. It can better absorb impact forces and reduce wear in complex working environments, thereby extending the service life of the measuring pipeline 2 and improving its reliability.
[0053] like Figure 2 and Figure 5 As shown, optionally, the cooling pipeline structure also includes an oil dipstick 5. The oil dipstick 5 can adopt an existing structure, and the oil dipstick 5 can measure the oil level more conveniently and intuitively, thereby better monitoring the amount of lubricating oil in the cooling pipeline structure and ensuring the normal operation of the cooling pipeline structure. The first end of the oil dipstick 5 is inserted into the second section 22, and the second end of the oil dipstick 5 is detachably connected to the second section 22, so that the operator can easily remove the oil dipstick 5 from the measuring pipeline 2 and check the oil level, thereby realizing the oil level measurement of the second section 22, that is, the oil level measurement in the cavity of the reducer 100. The provision of the breathable component 3 helps to achieve accurate measurement of the oil level inside the cooling pipeline structure, thereby ensuring the stable operation of the cooling pipeline structure.
[0054] like Figure 2 、 Figure 4 and Figure 5As shown, optionally, the cooling pipeline structure also includes a second oil inlet pipeline 41 and a second oil outlet pipeline 42. By adding pipelines, the motor cavity is connected to the reducer 100 cavity, which is used for oil return to the motor cavity. A fourth through hole 43 and a fifth through hole 44 are provided on the motor flange 200, and the fourth through hole 43 and the fifth through hole 44 are both connected to the motor cavity. A sixth through hole is provided on the brake flange 300, and the sixth through hole is connected to the reducer 100 cavity. The first end of the second oil inlet pipeline 41 is connected to the first oil inlet pipeline 11, the second end of the second oil inlet pipeline 41 is connected to the fourth through hole 43, the first end of the second oil outlet pipeline 42 is connected to the fifth through hole 44, and the second end of the second oil outlet pipeline 42 is connected to the sixth through hole. This cooling pipeline structure adds an inlet for forced cooling oil, namely the second end of the first oil inlet line 11. This inlet is divided into two cooling oil channels via a pipe joint: one cooling oil channel enters the motor cavity through the second oil inlet line 41, and the other lubricating oil channel enters the cavity of the reducer 100 through the first end of the first oil inlet line 11. The two cooling oil channels ultimately merge in the cavity of the reducer 100 and are discharged through the first oil outlet line 12 at the cooling oil outlet.
[0055] The provision of the second oil inlet line 41 and the second oil outlet line 42 enables the lubricating oil to effectively cool not only the reducer 100 but also the motor. After the lubricating oil cooled by the cooler enters the cavity of the reducer 100 through the first oil inlet line 11, some of the lubricating oil enters the cavity of the motor through the second oil inlet line 41 for cooling. It then flows out from the fifth through-hole 44 and returns to the cavity of the reducer 100 through the second oil outlet line 42, and finally returns to the cooler through the first oil outlet line 12. This achieves simultaneous cooling of the reducer 100 and the motor, improves cooling efficiency, helps alleviate the problem of poor heat dissipation of the reducer 100 and the motor, and reduces the risk of heat from the motor cavity affecting the reducer 100. This cooling pipe structure improves the structure of the brake flange 300 and the motor flange 200, increases the oil flow channel, and borrows the original through-hole structure of the planetary carrier of the reducer 100 to achieve communication between the opened hole and the cavity of the reducer 100, thereby achieving the cooling oil flow function.
[0056] like Figure 4 、 Figure 6 and Figure 7 As shown, optionally, the fourth through hole 43 is arranged on the upper side of the motor flange 200, and the fifth through hole 44 is arranged below the fourth through hole 43, so that the lubricating oil can flow smoothly into the cavity of the motor, and flow out through the second oil outlet pipe 42 and return to the cavity of the reducer 100, effectively improving the efficiency and cooling effect of the entire cooling pipe structure, optimizing the flow path of the lubricating oil, and improving the lubrication effect.
[0057] like Figure 2 、 Figure 4 and Figure 5As shown, the first oil outlet line 12 can optionally be positioned below the motor flange 200, and the fifth through hole 44 can be positioned on the side of the motor flange 200. This allows the second oil outlet line 42 and the first oil outlet line 12 to be positioned on different sides of the motor. This improves the cooling system layout, effectively mitigates interference between the second oil outlet line 42 and the first oil outlet line 12, and enhances the layout rationality and maintenance ease of the entire cooling system. Furthermore, this optimizes the flow path of the lubricating oil, the cooling medium, helping to enhance the cooling effect, improve the ease of installation, and enhance the overall compactness of the cooling system.
[0058] like Figure 2 、 Figure 6 and Figure 8 As shown, the addition of a cooling pipeline structure to the free-fall winch reducer 100 can alleviate the heat transferred from the motor into the reducer 100, lowering the temperature of the reducer 100 itself, allowing the reducer 100 to adapt to more severe operating conditions and thereby extending the service life of the lubricating oil and oil seals within the reducer 100. Since the brake friction plate 6 is located between the motor and reducer 100, when the temperature of the motor and reducer 100 drops, the heat transfer to the friction plate 6 between them is reduced, thereby helping to lower the temperature of the friction plate 6, reducing the risk of damage to the parking friction plate 6 due to overheating, and ensuring that the friction plate 6 maintains a good braking effect.
[0059] In this embodiment, the first oil inlet pipeline 11, the first oil outlet pipeline 12, the oil outlet connection portion 121, the first section 21, the second section 22, the flexible connection portion, the air vent pipeline 31, the second oil inlet pipeline 41, the second oil outlet pipeline 42 and other structures can all include a pipe body for achieving fluid transportation and a connecting structure for achieving pipe body connection. The connecting structure can be selected from existing structures, including but not limited to connecting flanges and pipe joints. The connection method can be threaded, welded or other methods, as long as the pipe body can achieve a reliable connection. It is understood that the cooling pipeline structure also includes necessary structures for connection, support, drive, positioning, limiting, sealing and control functions to enable the normal operation of the cooling pipeline structure. The parameters such as the shape, size, material and number of settings of each part of the cooling pipeline structure can be determined as needed to achieve the corresponding function.
[0060] The implementation principle of a cooling pipeline structure for a free fall winch in an embodiment of the present application is as follows: a first oil inlet pipeline 11 connects the oil outlet of the cooler with the first through hole on the brake flange 300, so that the cooled lubricating oil can enter the cavity of the reducer 100 through the first through hole, thereby realizing cooling and lubrication of the inside of the reducer 100; at the same time, the first oil outlet pipeline 12 connects the second through hole with the oil inlet of the cooler, so that the lubricating oil passing through the reducer 100 can flow back to the cooler through the second through hole for re-cooling, thereby forming a continuous circulation cooling pipeline structure; the measuring pipeline 2 is connected to the first oil outlet pipeline 12 and is designed with an oil level measurement function at its second end, which monitors the oil level status in the reducer 100 at any time, ensures reliable lubrication, and realizes cooling of the reducer 100; the breathable component 3 ensures the air pressure balance inside and outside the cavity of the reducer 100 by connecting to the third through hole on the brake flange 300, so that the lubricating oil can flow smoothly, thereby achieving the effect of effectively cooling and maintaining internal components.
