Description

Technical Field

[0001] This application relates to the field of excavator equipment technology, specifically a special attachment for railway excavator operation. Background Technology

[0002] When railway excavators are handling stone or timber, they often need to use special attachments to clamp the stone or timber, usually hydraulic rotary stone grippers (or modified timber grippers). Their core function is to achieve 360-degree rotation and clamping through hydraulic drive, adapting to the stone handling needs under different working conditions. These attachments control the opening and closing of the grippers through hydraulic valve blocks and pipelines, supporting free clockwise / counterclockwise rotation, and can precisely adjust the stone clamping angle to adapt to complex space operations such as railway slope and ballast clearing.

[0003] For example, patent CN221030373U discloses a linkage rod structure for a hydraulic gripper of an excavator's mechanical claw. This patent, through the cooperation of a first connecting rod, allows the left gripper to rotate around the first connecting rod, thereby ensuring the stability of the left gripper's rotation. Through the cooperation of a second connecting rod, it allows the right gripper to rotate around the second connecting rod, thereby ensuring the stability of the right gripper's rotation. Through the cooperation of the linkage rod body, it can drive the other gripper to rotate when the left or right gripper rotates at a certain angle, thereby enabling the two grippers to move synchronously and improving the gripping efficiency.

[0004] In the aforementioned patent, the excavator gripper improves gripping efficiency by setting two sets of freely rotating grippers. However, because these grippers are centrally rotating, they have relatively sharp ends and edges. When in contact with easily damaged stones, the concentrated stress can cause scratches, pits, or even cracks on the stone surface. For example, when gripping soft limestone, the edges of the grippers may scrape off the surface material, and the sharp ends may repeatedly scratch the stone surface, forming multiple intersecting scratches. This damages the stone's appearance and affects its subsequent use value (such as as decorative stone or building surface material). Therefore, it is necessary to provide a special attachment for railway excavators with protective devices to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] like Figures 1-2 As shown, this application provides a special attachment for railway excavator operations, including an excavator arm 1. The excavator arm 1 is mounted on the excavator and is used to assist the excavator in outdoor excavation and other work. The excavator arm 1 includes a connecting block 11, which is fixedly mounted on the excavator. A first connecting arm 12 is rotatably mounted on one side of the connecting block 11, and a second connecting arm 13 is rotatably mounted on one side of the first connecting arm 12. A first electric cylinder 14 is provided between the second connecting arm 13 and the first connecting arm 12. The first electric cylinder 14 is adapted to be connected to the main control room of the excavator, so that the operator can freely control the extension and retraction of the first connecting arm 12 and the second connecting arm 13, thereby flexibly adjusting the length and working range of the excavator arm 1. Meanwhile, a handling component 2 is provided on the second connecting arm 13. The handling component 2 is used to handle materials such as stones in the construction site. The handling component 2 includes a connecting plate 21, which is rotatably installed on the side of the second connecting arm 13 away from the first connecting arm 12. At the same time, a second electric cylinder 15 is rotatably installed at the connection between the connecting plate 21 and the second connecting arm 13. Thus, the workers can freely change the working angle of the handling component 2 by controlling the first electric cylinder 14 and the second electric cylinder 15, thereby completing the material handling task more accurately. A fixing plate 22 is installed at the bottom of the connecting plate 21, and a motor (not shown in the figure) is fixedly installed on one side of the connecting plate 21. The output end of the motor passes through the connecting plate 21 and is fixedly connected to the fixing plate 22. At the same time, multiple sets of clamping components 3 are symmetrically arranged at the bottom of the fixing plate 22. The clamping components 3 include a slide rail 31 fixedly installed at the bottom of the fixing plate 22. A gripper 32 is slidably installed on the slide rail 31. The gripper 32 is a long strip plate structure. At the same time, a cylinder 33 is fixedly installed on one side of the slide rail 31. The output end of the cylinder 33 is fixedly connected to the gripper 32, so that the cylinder 33 is suitable for driving the gripper 32 to move on the slide rail 31, thereby bringing the two sets of grippers 32 closer or further apart, realizing the clamping function, and thus quickly realizing the clamping and transportation of stone.

[0018] like Figures 2-4 As shown, in order to ensure that the handling component 2 can firmly grip stones of different hardness when handling them, a protective component 4 is also provided on the gripper 32. The protective component 4 includes a protective sleeve 41. The outermost layer of the protective sleeve 41 is made of a flexible material with good elasticity and cushioning performance. The inner part is provided with multiple sets of wave-shaped undulations. These undulating structures can better contact the stone surface, increase friction, and prevent the stone from slipping during handling. Meanwhile, a receiving cavity 42 is provided inside the protective sleeve 41. The size of the receiving cavity 42 is adapted to the size of the end of the gripper 32. A mounting ring 43 is provided on the top of the protective sleeve 41. A hole suitable for the gripper 32 to pass through is provided at the center of the mounting ring 43. A wing bolt 44 is threaded on one side of the mounting ring 43. The wing bolt 44 is suitable for passing through the mounting ring 43 to achieve a firm connection between the protective sleeve 41 and the gripper 32. Meanwhile, multiple sets of through connecting holes 34 are also installed on the gripper 32. The size of the connecting hole 34 is adapted to the size of the wing bolt 44 and is used to cooperate with the wing bolt 44. When the stone to be transported is a fragile material, the sharp edges of the ordinary gripper 32 can easily cause the stone to break when it is used to clamp the material. At this time, a protective component 4 can be added to the front end of the gripper 32 through the cooperation of the wing bolt 44 and the connecting hole 34, so that the stone can be flexibly clamped and transported to the predetermined work position. Furthermore, since multiple sets of connecting holes 34 are provided on the gripper 32, the protective component 4 can extend the length of the gripper 32 to adapt to materials of different sizes. In summary, by setting up the protective component 4, this device provides a stable gripping force for the stone through the flexible material and wavy structure of the protective sleeve 41, avoiding damage to the stone during transportation. Furthermore, by adjusting the position of the protective component 4, the length of the gripper 32 can be flexibly extended.

[0019] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
