Description

Technical Field

[0001] This utility model relates to the field of winches, and in particular to a winch with bidirectional rope delivery function. Background Technology

[0002] A winch is a mechanical device mainly used to provide power when hoisting, tensioning or lifting heavy objects. It is widely used in construction sites, mines, ports, hoisting operations and other places. According to different uses and designs, winches can be divided into manual winches, electric winches, hydraulic winches, etc.

[0003] Many existing traditional winches are single-sided lifting mechanisms, which means that in certain situations, if a dual function of lowering one end and raising the other is required, two winches are needed. However, synchronizing two winches is difficult and cannot meet actual usage needs, making them impractical. Therefore, a winch with bidirectional rope output function is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a winch with bidirectional rope output function, which aims to improve the existing technology of some traditional winches, which are mostly single-sided lifting and lowering modes. This means that in certain situations, if it is necessary to achieve the dual function of one end descending and the other end rising, two winches need to be used, but it is difficult to synchronize the two winches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winch with bidirectional rope delivery function, comprising a frame, with drums provided on both the left and right sides of the frame, a connecting shaft passing through and fixedly connected to the middle of the drums, bearings installed on both the left and right sides of the connecting shaft, the connecting shaft being rotatably connected to the frame via the bearings, a housing fixedly connected to the rear of the frame, the connecting shaft passing through and rotatably connected to the housing, a drive assembly jointly installed in the middle of the frame and the housing, a lubrication mechanism installed on the upper part of the housing, and the drive assembly including a motor. The motor is fixedly connected to the frame. The output end of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through and is rotatably connected to the outer casing. A drive gear is fixedly connected to the rear of the rotating shaft. A first driven gear meshes with both the left and right sides of the drive gear. A second driven gear meshes with the two first driven gears on opposite sides. A drive gear meshes with the two second driven gears on opposite sides. The connecting shaft passes through and is fixedly connected to the drive gear. The first and second driven gears are rotatably connected to the inner wall of the outer casing.

[0006] As a further description of the above technical solution:

[0007] The lubrication mechanism includes an outer cylinder that penetrates and is fixedly connected to the outer shell. An oil injection rod is slidably connected to the middle of the outer cylinder, and an adjusting rod is rotatably connected to the top of the oil injection rod. The adjusting rod penetrates and is threadedly connected to the outer cylinder.

[0008] As a further description of the above technical solution:

[0009] The top surface of the oil injection rod is fixedly connected to the left and right sides with limiting rods, and the limiting rods are slidably connected to the outer cylinder.

[0010] As a further description of the above technical solution:

[0011] A connection port is provided on the upper rear side of the outer cylinder.

[0012] As a further description of the above technical solution:

[0013] An oil injection port is provided on the upper rear side of the oil injection rod, and the size and position of the oil injection port are adapted to the connection port.

[0014] As a further description of the above technical solution:

[0015] The lower part of the oil injection rod has multiple oil outlets, and the lower part of the oil injection rod has an oil guide groove, with the oil outlets connected to the oil guide groove.

[0016] As a further description of the above technical solution:

[0017] The middle part of the oil injection rod is hollow, and the lower part of the oil injection rod is tapered.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting up the mutual cooperation between the frame and components such as the motor, rotating shaft, driving gear, first driven gear, second driven gear and drive gear, the device can realize the dual functions of lifting and lowering, and can achieve mechanical synchronization without any difference in lifting and lowering, making it more practical.

[0020] 2. In this utility model, by setting up the cooperation between components such as the outer cylinder, the oil injection rod, the adjusting rod, and the limiting rod, the device can lubricate the gear set without opening the outer shell. Furthermore, through the cooperation of the above components, the oil injection port can be sealed when not in use, preventing the intrusion of external impurities. During oil injection and lubrication, the height of the oil injection rod decreases, and with the cooperation of the oil outlet and the oil guide groove, more precise oil injection operation can be achieved, making it more practical.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a winch with bidirectional rope delivery function, comprising a frame 1, which is the main frame of the winch and is used to install and connect various components. A drum 4 is provided on both the left and right sides of the frame 1 for winding the rope. The outer surface of the drum 4 has grooves for guiding the rope. A connecting shaft 41 is fixedly connected through and to the middle of the drum 4 for mounting the drum 4. Bearings 5 ​​are installed on both the left and right sides of the connecting shaft 41 for mounting the connecting shaft 41 to the frame 1 and for rotating the drum 4. The connecting shaft 41 is rotatably connected to the frame 1 via the bearings 5. A housing 2 is fixedly connected to the rear of the frame 1 for protecting the gear set. The connecting shaft 41 is rotatably connected to the housing 2. A drive assembly 3 is installed in the middle of the frame 1 and the housing 2 for driving the winch. A lubrication mechanism 6 is installed on the upper part of the housing 2 to facilitate lubrication of the gears in the gear set by the operator.

[0032] Furthermore, the drive assembly 3 includes a motor 31 for driving the winch. The motor 31 is fixedly connected to the frame 1. The output end of the motor 31 is fixedly connected to a rotating shaft 36 via a coupling, which is used to connect to the drive gear 32. The rotating shaft 36 passes through and is rotatably connected to the housing 2. The rear part of the rotating shaft 36 is fixedly connected to the drive gear 32, which is used to drive the first driven gear 33. The left and right parts of the drive gear 32 are each meshed with a first driven gear 33, which is used to connect to the second driven gear 34. The two first driven gears... Two driven gears 34 are meshed on opposite sides of the wheels 33. Two driven gears 34 are meshed on opposite sides of the wheels 33. They are used to drive the drum 4 to rotate via the connecting shaft 41, and to coordinate the winding and unwinding of the rope, thereby coordinating the lifting and lowering of the material. The connecting shaft 41 and the drive gear 35 are connected through and fixedly connected. The driven gears 33 and 34 are rotatably connected to the inner wall of the outer casing 2. The driving gear 32, the driven gear 33, the driven gear 34 and the drive gear 35 together form a gear set.

[0033] like Figure 6 - Figure 7 As shown, a rope is wound around the outside of the drum 4 for lifting heavy objects; the rope can be a steel wire rope.

[0034] like Figure 4 - Figure 5As shown, the lubrication mechanism 6 includes an outer cylinder 61, which is used to connect various components. The outer cylinder 61 is connected to the outer shell 2 through and fixedly. An oil injection rod 62 is slidably connected to the middle of the outer cylinder 61, which is used to lubricate the gear set with oil. An adjusting rod 63 is rotatably connected to the top of the oil injection rod 62, which is used to adjust the height of the oil injection rod 62 to cooperate with the opening and closing of the oil injection port 621. The adjusting rod 63 is connected to the outer cylinder 61 through and threadedly. A limiting rod 64 is fixedly connected to the left and right sides of the top surface of the oil injection rod 62, which is used to adjust the movement direction of the oil injection rod 62 so that it can only move up and down. The limiting rod 64 is connected to the outer cylinder 61 through and slidably.

[0035] Furthermore, the upper rear side of the outer cylinder 61 is provided with a connecting port 611, which is used to connect with the oil inlet 621 when the oil injection rod 62 descends. The upper rear side of the oil injection rod 62 is provided with an oil inlet 621, the size and position of which are adapted to the connecting port 611. The lower part of the oil injection rod 62 is provided with multiple oil outlets 622, which are used to discharge oil. The lower part of the oil injection rod 62 is provided with an oil guide groove 623, which is used to guide the lubricating oil to the drive gear 32. The oil outlets 622 are connected to the oil guide groove 623. The middle part of the oil injection rod 62 is hollow, and the lower part of the oil injection rod 62 is tapered. The lower part of the oil injection rod 62 does not directly contact the drive gear 32.

[0036] Working principle: When in use, the motor 31 is turned on, and the motor 31 will drive the rotating shaft 36 to rotate. When the rotating shaft 36 rotates, the driving gear 32 fixed to it will rotate, thereby driving the first driven gear 33 meshing with it. At this time, the second driven gear 34 meshing with the first driven gear 33 will rotate, thereby driving the driving gear 35 meshing with it to rotate. Since the connecting shaft 41 is fixed to the driving gear 35, when the driving gear 35 rotates, the connecting shaft 41 will rotate accordingly, thereby driving the drum 4 fixed to it to rotate, thereby realizing the winding and unwinding of the rope to achieve the lifting or lowering of the heavy object.

[0037] When the gear set needs lubrication, rotate the adjusting rod 63 to move the oil injection rod 62 downward, thereby connecting the oil injection port 621 on the oil injection rod 62 with the connecting port 611 on the outer cylinder 61. Then, oil can be injected into the oil injection rod 62 through the oil injection port 621. After the lubricating oil enters the oil injection rod 62, it will flow through the oil outlet 622 to the guide groove 623, and then flow through the guide groove 623 to the driving gear 32. When the driving gear 32 rotates, it will drive the lubricating oil to the first driven gear 33, then from the first driven gear 33 to the second driven gear 34, and finally to the drive gear 35, thus completing the overall lubrication of the gear set.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
