Description

Technical Field

[0001] This utility model relates to the field of railway vehicle tipper unloading technology, and in particular to a hook-and-hook boom device for a tipper. Background Technology

[0002] The tippler unloading system is a large-scale, automated, and efficient unloading equipment used to unload bulk materials such as coal, ore, and chemical raw materials loaded in open railway wagons. The car shifter is an auxiliary device in the tippler unloading system used to traction and dispatch railway vehicles.

[0003] For general-purpose railway open wagons, the tippler unloading system uses a disengagement and unloading operation, while the traction dispatcher relies on its boom to achieve traction and dispatching of the open wagons. In the 1990s, to improve efficiency, my country imported special-purpose railway open wagons with slewing couplers. The tippler unloading system in these cases required a non-disengagement and unloading operation. When traction is required for these open wagons, the traction dispatcher's boom must be lowered above the couplers between the two open wagons to achieve traction without uncoupling, also known as coupling operation. Because the traditional boom, when operating between open wagons without disengagement, interfered with the open wagon accessories, my country imported a traction dispatcher with a telescopic boom, using the telescopic boom for coupling and traction. Currently, non-disengagement and unloading of railway-specific open wagons can only be achieved using a telescopic boom, but the telescopic boom has a complex structure, is heavy, costly, has high maintenance costs, and is difficult to install. Furthermore, the traction dispatcher's boom can only perform hooking operations, not coupling operations. Therefore, in summary, it is necessary to provide a new type of car-pulling mechanism with a tilting and hooking boom for hooking and traction operations of open wagons on railways that do not require uncoupling, thereby overcoming the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned technical problems, a hook arm device for a car-pulling machine is provided. The technical means employed in this invention are as follows:

[0005] A car-pulling mechanism hook boom device includes: a car body, a boom, a linkage mechanism, and a drive unit. One end of the boom is hinged to the car body, and the other end has a U-shaped groove. The drive unit is fixed to the car body, and the boom and the drive unit are connected by a linkage mechanism. The drive unit drives the boom to reciprocate between the horizontal and vertical directions through the linkage mechanism. The maximum radius of rotation r of the boom is less than the distance R from the railway open wagon attachment to the boom's rotation center.

[0006] Furthermore, when the tractor pulls a railway train, the boom is in a horizontal position; when the tractor returns or is not in operation, the boom is in a vertically raised position.

[0007] Furthermore, the front end width 'a' of the boom is less than the distance A between the two open wagon sections.

[0008] Furthermore, the linkage mechanism includes a first link and a second link, the output end of the drive unit is connected to one end of the first link, the other end of the first link is hinged to one end of the second link, and the other end of the second link is hinged to the upper arm.

[0009] Furthermore, the first member is a straight rod, and the second member is a V-shaped rod with an opening angle greater than 90°.

[0010] Furthermore, the drive unit is a motor.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The hook arm device for the car-pulling machine provided by this utility model has a simple structure, is safe and reliable, and is lightweight, greatly reducing installation and maintenance costs.

[0013] 2. The hook-and-pull boom device provided by this utility model replaces the telescopic boom in the prior art with a simpler and more effective method of using a tilting boom, thus realizing the hook-and-pull operation of railway open wagons. By limiting the size and hinge point position of the tilting boom, the boom will not interfere with the railway open wagon accessories during the tilting process, solving the problem in the prior art where the tilting boom cannot achieve hook-and-pull operation due to interference with railway open wagon accessories.

[0014] Based on the above reasons, this utility model can be widely promoted in the fields of railway vehicles, etc. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This invention provides a more economical and simpler hook arm device for tipper machines, which can reduce the weight of tipper machines and increase the gross profit margin of tipper products.

[0022] This utility model discloses a car-pulling mechanism with a hook-locking boom, comprising a car body 1, a boom 2, a linkage mechanism 3, and a drive unit 4. The drive unit 4 is fixed to the car body 1. The boom 2 is connected to the drive unit 4 via the linkage mechanism 3. One end of the boom 2 is hinged to the car body 1. The drive unit 4, through the linkage mechanism 3, enables the boom 2 to rotate about the hinge point between the boom 2 and the car body 1. The drive unit 4 drives the boom 2 to reciprocate between the horizontal and vertical directions via the linkage mechanism 3. The rotation angle range of the boom 2 is 0-90°. The other end of the boom 2 is provided with a U-shaped groove for realizing the hook-locking and traction operation of the car-pulling mechanism. This U-shaped groove is compatible with railway car couplers.

[0023] When the traction machine pulls a train, boom 2 is in a horizontal position, such as Figure 1 As shown. When the scooter returns or is not in operation, boom 2 is in a vertically raised position, as shown. Figure 2 As shown.

[0024] Among them, the width 'a' at the front end of boom 2 is less than the distance A between the two open wagon sections, such as... Figure 3 As shown. Simultaneously, when boom 2 is pitching, boom 2 must not interfere with the railway wagon attachments. That is, by reasonably selecting the position of the boom 2 hinge point, the maximum slewing radius r of boom 2 should be less than the distance R from the railway wagon attachments to the slewing center of boom 2, such as... Figure 1 As shown.

[0025] In this embodiment, the linkage mechanism 3 includes a first link and a second link. The output end of the drive unit 4 is connected to one end of the first link, the other end of the first link is hinged to one end of the second link, and the other end of the second link is hinged to the boom 2. The first link is a straight rod, and the second link is a V-shaped rod with an opening angle greater than 90°. The structural composition of the linkage mechanism 3 is not limited to this structural form. The linkage mechanism 3 of this utility model can adopt any structural composition that enables the boom 2 to reciprocate between the horizontal and vertical directions.

[0026] In this embodiment, the drive unit 4 can be a drive device such as a motor, and the motor can adopt an existing structural form. It should be noted that the drive unit 4 includes, but is not limited to, a motor.

[0027] This invention employs a simpler and more effective tilting boom to replace the telescopic boom in existing technologies, enabling hooking and traction operations on open wagons without disassembling them. By limiting the size and hinge point position of the tilting hooking boom, this invention prevents interference between the boom and railway open wagon attachments during the tilting process, thus solving the problem in existing technologies where interference with railway open wagon attachments prevents hooking operations.

[0028] Compared with the telescopic hook boom in the prior art, the pitch hook boom of this utility model has a simpler structure, is safer and more reliable, and is lighter in weight, greatly reducing installation and maintenance costs.

[0029] After implementation, this utility model can be applied to tippler projects on the Daqin Railway or other ports at home and abroad. It can greatly reduce the weight of the car shifter in the non-disembarkation tippler system, reduce the cost of the car shifter, and increase the gross profit margin of the tippler system.

[0030] Existing wagon towing machines with tilting booms can only perform hooking operations, enabling the towing of general-purpose open wagons that are towed and detached. However, hooking operations for open wagons that are not to be detached can only be achieved using telescopic booms. This invention utilizes a tilting boom to achieve the hooking function, allowing it to be used for towing operations of open wagons that are not to be detached.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
