Description

Technical Field

[0001] The utility model relates to the technical field of traction systems, in particular to a shunting winch for a port transportation traction system. Background Art

[0002] Shunting winch is a kind of traction and transportation equipment, which is widely used in places where trains need to be towed and dispatched to load and unload goods, such as railway coal bunker loading stations, power plants, steel mills, port terminals, etc. It can also be used in conjunction with fast loading stations to carry out fast loading and realize various shunting operations.

[0003] A shunting winch primarily consists of a motor, coupling, brake, reducer, and friction wheel. When the winch is operating, the motor starts and outputs power, which is then transferred via the coupling to the reducer for torque reduction and torque increase. The power from the reducer then rotates the friction wheel, which then pulls the vehicle via a wire rope. Depending on the number of friction wheels, shunting winches can be divided into single-, double-, and four-wheel shunting winches. A four-wheel shunting winch consists of two rotating shafts, each of which extends through a housing and is connected to a friction wheel.

[0004] In view of the above-mentioned existing technologies, the inventors believe that when the dispatching winch is performing traction operations, the traction force is borne by the rotating shaft and the friction wheel thereon, and high requirements are placed on the supporting performance and strength of the rotating shaft. Especially in operating situations where the traction weight is large, the conventional dispatching winch rotating shaft has insufficient supporting performance and strength, a short service life, and poor working stability. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a shunting winch for a port transport traction system, which improves the stress state of the rotating shaft and the friction wheel, enhances the supporting performance and strength of the rotating shaft, can withstand greater traction, and operates more stably and reliably.

[0006] To achieve the above-mentioned object, the present invention provides a shunting winch for a port transport tractor system, comprising a reduction gearbox and two rotating shafts rotatably connected to the reduction gearbox, with both ends of each rotating shaft passing through the reduction gearbox and fixed with a friction wheel; and further comprising two support members, the two support members being respectively located on either side of the reduction gearbox, with the ends of each rotating shaft passing through the friction wheel and connected to the corresponding support member.

[0007] The support member includes a connecting plate frame, a connecting beam, two eccentric sleeves and two bearings; the bearing is embedded in the eccentric sleeve, the eccentric sleeve is fixed on the connecting plate frame, one end of the connecting beam is fixedly connected to the reduction gear box body, and the other end is fixedly connected to the connecting plate frame; one end of the rotating shaft passes through the friction wheel and is arranged in the corresponding bearing inner ring, and the rotating shaft is rotatably connected to the eccentric sleeve through the bearing.

[0008] Furthermore, the connecting plate frame includes a connecting plate and two steel sleeves, the eccentric sleeve is fixed in the corresponding steel sleeve, each of the steel sleeves is inserted into the connecting plate and fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the reduction gear box body through a connecting beam.

[0009] Furthermore, there are two connecting plates, which are parallel to each other and distributed on the outside of the two ends of the steel sleeve. A rib plate is provided between the two connecting plates, and both sides of the rib plate are fixedly connected to the connecting plates, and both ends of the rib plate are fixedly connected to the steel sleeve.

[0010] Furthermore, a positioning retaining ring is formed on the outer edge of one end of the eccentric sleeve, and the positioning retaining ring abuts against the end surface of the steel sleeve away from the friction wheel. The positioning retaining ring and the steel sleeve are connected by bolts.

[0011] Furthermore, a baffle is fixed to the end face of the rotating shaft, and the baffle is located outside the bearing and fits with the outer end face of the bearing; and a cover plate is fixedly connected to the end of the eccentric sleeve away from the friction wheel.

[0012] Beneficial effects of the utility model:

[0013] This utility model utilizes a shunting winch for a port transport tractor system. This design incorporates a support frame to reinforce the ends of the rotating shaft, improving the stress on the friction wheel and the rotating shaft. This reduces the shear force experienced by the traditional rotating shaft during traction, resulting in a more balanced force distribution and providing additional support. The overall structure is more stable and can withstand greater traction. Furthermore, the inclusion of an eccentric sleeve within the support facilitates alignment adjustment of the two rotating shafts, making installation more convenient and precise, while reducing vibration and wear caused by misalignment during equipment operation. Furthermore, a variable mounting clearance facilitates adjustment of the radial clearance of the bearings, ensuring optimal bearing performance and service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] The utility model discloses a shunting winch for a port transportation traction system.

[0023] Reference Figures 1 to 2 A shunting winch for a port transport traction system includes a reduction gear box 1 and two rotating shafts 2 rotatably connected to the reduction gear box 1. Both ends of each rotating shaft 2 pass through the reduction gear box 1 and are fixed with friction wheels 3; support members 4 are also provided on both sides of the reducer box, and the ends of each rotating shaft 2 pass through the friction wheel 3 and are connected to the corresponding support members 4.

[0024] Reference Figures 3 and 4 The support member 4 includes a connecting plate frame 41, a connecting beam 5, two eccentric sleeves 42 and two bearings 43; the bearings 43 are embedded and tightened in the eccentric sleeves 42, and the eccentric sleeves 42 are installed on the connecting plate frame 41. One end of the connecting beam 5 is fixedly connected to the reduction gear box body 1, and the other end is fixedly connected to the connecting plate frame 41. Then the connecting plate frame 41 is relatively fixed to the reduction gear box body 1 through the connecting beam 5; one end of the rotating shaft 2 passes through the friction wheel 3 and is arranged on the inner ring of the corresponding bearing 43. The rotating shaft 2 is rotatably connected to the eccentric sleeve 42 through the bearing 43.

[0025] The support member 4 is provided by reinforcing the ends of the rotating shaft 2 and is fixedly connected to the reduction gear box 1, thereby improving the stress state of the friction wheel 3 and the rotating shaft 2, reducing the shear force applied to the rotating shaft 2 of the traditional structure during pulling, and providing a more balanced force. It also provides additional support, making the overall structure more stable and capable of withstanding greater traction. Furthermore, the eccentric sleeve 42 in the support member 4 facilitates adjustment of the centering of the two rotating shafts 2 by rotating the eccentric sleeve 42, making installation more convenient and more precise, reducing vibration and wear caused by misalignment during equipment operation, and providing a variable installation gap to facilitate adjustment of the radial clearance of the bearing 43, ensuring the good performance and service life of the bearing 43.

[0026] Reference Figure 5 and Figure 6The connecting plate frame 41 includes a connecting plate 411 and two steel sleeves 412. The eccentric sleeves 42 are fixed in the corresponding steel sleeves 412. Each steel sleeve 412 is inserted into the connecting plate 411 and fixedly connected to the connecting plate 411. The connecting plate 411 is fixedly connected to the reduction gearbox body 1 via the connecting beam 5. In this embodiment, two connecting plates 411 are provided. The two connecting plates 411 are parallel and distributed on the outside of the two ends of the steel sleeves 412. A rib plate 413 is provided between the two connecting plates 411. The two sides of the rib plate 413 are fixedly connected to the connecting plate 411, and the two ends of the rib plate 413 are fixedly connected to the steel sleeves 412. The provision of multiple connecting plates 411 and rib plates 413 ensures the structural strength and stability of the connecting plate frame 41, thereby ensuring the reliability of the support effect of the support member 4.

[0027] A positioning retaining ring 421 is formed on the outer edge of one end of the eccentric sleeve 42. The positioning retaining ring 421 abuts against the end face of the steel sleeve 412 away from the friction wheel 3, and plays an axial positioning role for the installation of the eccentric sleeve 42; the positioning retaining ring 421 and the steel sleeve 412 are connected by bolts to facilitate subsequent disassembly and maintenance. The end face of the rotating shaft 2 is bolted to a baffle 45. The baffle 45 is located on the outside of the bearing 43 and fits against the outer end face of the bearing 43. The baffle 45 acts as a limiter for the bearing 43, ensuring the stability of the position of the bearing 43. The end of the eccentric sleeve 42 away from the friction wheel 3 is bolted to a cover plate 44. The cover plate 44 acts as a sealing and protective role for the eccentric sleeve 42, preventing external debris and dust from entering the eccentric sleeve 42, thereby reducing additional wear on the eccentric sleeve 42 and the bearing 43.
