Description

Technical Field

[0001] The present application relates to the technical field of winches, and in particular to a winch for a rail car. Background Art

[0002] During normal operation, a winch, limited by its structural design, can only apply force in one direction. For example, the steel rope is tightened when the motor is rotating forward, but the rope must be loosened when the motor is rotating reversely. In the ferroalloy smelting process, the iron-feeding carts carrying the molten iron and slag ladles must be moved horizontally along the laid track. Before the molten metal is discharged from the furnace, the carts are pulled under the furnace eye to hold the molten metal. After the molten metal is discharged from the furnace, the carts are pulled to the casting area for processing. Furthermore, the transport of the cast and cooled products to storage requires the carts to be moved back and forth along the tracks laid between the production workshop and the finished product warehouse to achieve product storage.

[0003] In the prior art, a winch is set at each end of the cart. When pulling back and forth, one winch is operated respectively, and then the steel rope of the other winch is loosened and pulled to the parking position of the cart to prepare for pulling back the cart. Since the two winches are far apart, two people are required to operate them, which not only increases equipment and costs, but also makes the operation quite troublesome. Utility Model Content

[0005] The present application provides a winch for a rail cart, comprising a frame 1, a hoisting drum 2, a drive motor 3, a guide pulley 4, a redirecting pulley 5, and a hoisting steel rope 8; the frame 1 is arranged at both ends of the cart track 9, and the hoisting drum 2 is rotatably mounted on the frame 1 at the right end of the cart track 9, and its rotating shaft is connected to the rotating shaft of the drive motor 3 through a transmission belt. The outer ring of the hoisting drum 2 is coaxially mounted with a first hoisting disc 6 and a second hoisting disc 7, and the first hoisting disc 6 and the second hoisting disc 7 are both provided with a circular groove for the transmission arrangement of the hoisting steel rope 8. A guide pulley 4 is mounted in the middle of the frame 1 on the left side of the hoisting drum 2, and the redirecting pulley 5 is mounted on the frame 1 at the left end of the cart track 9. One end of the hoisting steel rope 8 is fixed to the right end of the cart 10, and the other end is wound through the first hoisting disc 6, the guide pulley 4, the second hoisting disc 7, and the redirecting pulley 5 in sequence, and is fixedly connected to the left end of the cart 10.

[0006] Optionally, in some solutions, the first hoisting disc 6 and the second hoisting disc 7 have the same structure, the cross section of the circular groove is a trapezoidal structure, and the width of the circular groove gradually decreases from the top to the bottom.

[0007] The technical solution provided by this application may have the following beneficial effects:

[0008] The renovation cost of this application is much lower than the cost of adding a winch equipment, which reduces the investment cost and operating cost of the equipment. Only one winch is needed, and one person can complete the cart pulling, which is very simple and quick to operate.

Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0016] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0017] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0018] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0019] In response to the above problems, an embodiment of the present application provides a winch for a rail-mounted trolley, which can reduce the investment cost and operating cost of the equipment and is simple and quick to operate.

[0020] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1 The winch for the rail cart includes a frame 1, a hoisting drum 2, a drive motor 3, a guide pulley 4, a redirecting pulley 5, and a hoisting rope 8; the frame 1 is arranged at both ends of the cart track 9, and the hoisting drum 2 is rotatably mounted on the frame 1 at the right end of the cart track 9, and its rotating shaft is connected to the rotating shaft of the drive motor 3 through a transmission belt. The outer ring of the hoisting drum 2 is coaxially mounted with a first hoisting disc 6 and a second hoisting disc 7, and the first hoisting disc 6 and the second hoisting disc 7 are both provided with a circular groove for the transmission arrangement of the hoisting rope 8. A guide pulley 4 is installed in the middle of the frame 1 on the left side of the hoisting drum 2, and the redirecting pulley 5 is installed on the frame 1 at the left end of the cart track 9. One end of the hoisting rope 8 is fixed to the right end of the cart 10, and the other end is wound through the first hoisting disc 6, the guide pulley 4, the second hoisting disc 7, and the redirecting pulley 5 in sequence, and is fixedly connected to the left end of the cart 10.

[0022] During operation, when the cart 10 needs to move to the right, the drive motor 3 is started to rotate the winch drum 2 clockwise, and the first winch disc 6 is rotated to pull the cart 10 to the right, so that the winch rope 8 passes through the guide pulley 4, the second winch disc 7, and the redirecting pulley 5 and is released to the left side of the cart 10. Similarly, when the cart 10 needs to move to the left, the drive motor 3 is started to rotate the winch drum 2 counterclockwise, and the second winch disc 7 is pulled and the redirecting pulley 5 is reversed, so that the cart 10 moves to the left, and the winch rope 8 passes through the guide pulley 4 and the first winch disc 6 and is released to the right side of the cart 10. By controlling the forward and reverse rotation of the drive motor 3, the cart 10 can be driven to reciprocate on the cart track 9. Only one winch is needed, and one person can complete the cart pulling, which reduces the investment cost and operating cost of the equipment.

[0023] In some embodiments, see Figure 2 The cross section of the circular groove is a trapezoidal structure, and the width of the circular groove gradually decreases from the top to the bottom.

[0024] During operation, the conical angle formed by the circular groove with a trapezoidal cross-section can increase the friction between the hoisting steel rope 8 and the wall of the circular groove when the hoisting steel rope 8 moves, and prevent the hoisting steel rope 8 from sliding in the circular groove during the rotation of the hoisting drum 2, causing the cart 10 to not move. The conical angle and the friction between the conical disk angle and the wire rope can be used to pull the cart back and forth. Only one winch is needed to achieve this, and the operation is simple.

[0025] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms include, comprise, or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
