DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0041] The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but should not be understood as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present 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 should not be understood as a limitation on the present application.

[0044] In the description of the present application, “plurality” means two or more than two, unless otherwise precisely and specifically specified.

[0045] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0046] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0047] As mentioned in the background technology, the hydraulic pipelines in the related technology may interfere with or even get entangled with other parts during the operation of the transportation equipment, thus affecting the normal operation of the equipment. The reason for this problem is that in the process of conventional material transportation, in order to adapt to different transportation distances and heights and provide flexible material handling solutions, telescopic parts will be added to the transportation equipment. During the extension and retraction process of the telescopic parts, the hydraulic pipelines connected to the telescopic parts inevitably need to be folded and stored.

[0048] In the related art, in order to provide necessary protection for the hydraulic pipeline when it is folded and stored, the hydraulic pipeline is wrapped with a retractable belt, and the retractable belt is folded and stored synchronously with the hydraulic pipeline to prevent the hydraulic pipeline from being damaged due to excessive bending. However, when the telescopic member is transported over a long distance, the retractable belt and the hydraulic pipeline will be long, making it very easy for the hydraulic pipeline to interfere with or even get entangled with other components when folded or unfolded.

[0049] Based on the above technical problems, an embodiment of the present application provides a hydraulic pipeline towing device. In this technical solution, the hydraulic pipeline towing device includes a towing assembly, a line-laying platform and at least one moving part. The line-laying platform and the towing assembly are used to be arranged on the equipment body of the transportation equipment. The moving part is used to be slidably connected to the equipment body. The towing assembly is configured to connect the telescopic part with one of the moving parts, and drive each moving part to slide in the same direction under the drive of the telescopic part. The line-laying platform is used to place the hydraulic pipeline, and each moving part is used to connect with the hydraulic pipeline to drive the hydraulic pipeline to unfold or fold on the line-laying platform. By setting the towing assembly and the moving part, the hydraulic pipeline can be unfolded or folded on the line-laying platform, which can avoid the hydraulic pipeline from interfering with or even entangled with other parts during operation, thereby avoiding affecting the normal operation of the equipment.

[0050] It should be noted that Figures 1 to 3 The schematic diagram of each component of the hydraulic pipeline towing device is shown. The specific structure of the remaining components of the hydraulic pipeline towing device is not limited to Figures 1 to 3 of examples.

[0051] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0052] Reference Figure 1 , Figure 2 and Figure 3 As shown, a hydraulic pipeline towing device provided in an embodiment of the present application is used to accommodate a hydraulic pipeline 100 arranged on a transport equipment, and the transport equipment includes an equipment body and a telescopic part 200, and the hydraulic pipeline 100 is connected to the telescopic part 200. It should be noted that the transport equipment can be various equipment in this field, such as a shield machine, an assembly line, etc. The transport equipment has a telescopic part 200 with reciprocating motion, and the equipment body of the transport equipment provides support for the telescopic part 200. The equipment body is not shown in the accompanying drawings, and the equipment body can be a truss with a supporting function, a mounting frame, etc. Other specific structures of the transport equipment are not limited here. In summary, the hydraulic pipeline towing device provided by this application can be applied to various different transport equipment with hydraulic pipelines 100 and telescopic parts 200.

[0053] The hydraulic pipeline towing device includes a traction component 300, a line-laying platform 400 and at least one moving part 500. The line-laying platform 400 and part of the traction component 300 are used to be arranged on the equipment body. The moving part 500 is used to be slidably connected to the equipment body. The traction component 300 is configured to connect the telescopic part 200 with one of the moving parts 500, and drive the moving parts 500 to slide in the same direction under the drive of the telescopic part 200. The line-laying platform 400 is used to place the hydraulic pipeline 100, and each moving part 500 is used to be connected to the hydraulic pipeline 100 to drive the hydraulic pipeline 100 to unfold or fold on the line-laying platform 400.

[0054] It should also be noted that Figures 1 to 3 The X, Y, and Z directions shown in are perpendicular to each other in the three-dimensional space.

[0055] In the above embodiment, the telescopic member 200 drives each movable member 500 to slide through the traction assembly 300, and the movable member 500 is connected to the hydraulic pipeline 100. The movable member 500 drives the hydraulic pipeline 100 to move, so that the hydraulic pipeline 100 can be unfolded or folded on the line-laying platform 400, which can avoid the hydraulic pipeline 100 from interfering with or even entangled with other components during operation, thereby avoiding affecting the normal operation of the equipment.

[0056] In a possible implementation, the traction assembly 300 includes a reversing fixed pulley 310 , a pulley assembly 320 , a first traction member 330 , and a second traction member 340 .

[0057] The reversing fixed pulley 310 is arranged on an extension line of the sliding direction of the moving member 500. Figure 1 As shown, each moving member 500 can move along Figure 1 As shown in the X direction and the opposite direction of the X direction, the moving member 500 is located between the reversing fixed pulley 310 and the telescopic member 200, one end of the first traction member 330 is connected to the telescopic member 200, and the other end is sequentially wound around the pulley assembly 320 and the reversing fixed pulley 310, and is connected to the moving member 500 away from the reversing fixed pulley 310, so that when the telescopic member 200 slides toward the reversing fixed pulley 310, that is, Figure 1 In the direction indicated by the X arrow, the moving member 500 away from the reversing fixed pulley 310 is driven to slide toward the reversing fixed pulley 310 to drive the hydraulic pipeline 100 to fold.

[0058] The second traction member 340 sequentially connects the telescopic member 200 and each moving member 500, and when the telescopic member 200 slides away from the reversing fixed pulley 310, that is, Figure 1 In the opposite direction indicated by the X arrow, the moving member 500 away from the reversing fixed pulley 310 is driven to slide away from the reversing fixed pulley 310 to drive the hydraulic pipeline 100 to unfold.

[0059] In the above embodiment, when the telescopic member 200 moves in the direction indicated by the X-arrow, the telescopic member 200 applies a pulling force to the first traction member 330, and the first traction member 330 drives the moving member 500 away from the reversing fixed pulley 310 to slide in the direction indicated by the X-arrow through the pulley assembly 320 and the reversing fixed pulley 310. When the moving member 500 away from the reversing fixed pulley 310 abuts against the adjacent moving member 500, it continues to drive the adjacent moving member 500 to slide in the direction indicated by the X-arrow. At this time, the hydraulic pipeline 100 between the moving member 500 away from the reversing fixed pulley 310 and the adjacent moving member 500 will be folded on the wire-laying platform 400, and the telescopic member 200 continues to move in the direction indicated by the X-arrow, and the above process will be repeated until all the moving members 500 slide in the direction indicated by the X-arrow, and the hydraulic pipeline 100 between each adjacent moving member 500 will be folded on the wire-laying platform 400.

[0060] When the telescopic member 200 moves in the opposite direction indicated by the X-arrow, the telescopic member 200 applies a pulling force to the second traction member 340, and the second traction member 340 first drives the moving member 500 away from the reversing fixed pulley 310 to move in the opposite direction indicated by the X-arrow. After the second traction member 340 and the hydraulic pipeline 100 between the moving member 500 away from the reversing fixed pulley 310 and its adjacent moving member 500 are unfolded, the adjacent moving member 500 is continued to be driven to slide in the opposite direction indicated by the X-arrow, and the above process is repeated until each moving member 500 slides in the opposite direction indicated by the X-arrow. At this time, the second traction member 340 and the hydraulic pipeline 100 between each adjacent moving member 500 are unfolded.

[0061] It can be understood that in the above process, when the movable member 500 moves in the direction indicated by the X-arrow, the first traction member 330 is subjected to the pulling force given by the telescopic member 200, and the second traction member 340 is not subjected to the force; when the movable member 500 moves in the opposite direction indicated by the X-arrow, the second traction member 340 is subjected to the pulling force given by the telescopic member 200, driving each movable member 500 to move in the opposite direction indicated by the X-arrow, and the first traction member 330 is subjected to the pulling force given by the movable member 500.

[0062] In one possible implementation, refer to Figure 2 and Figure 3 As shown, in order to improve the safety of the hydraulic pipeline 100 and protect the hydraulic pipeline 100, the second traction member 340 and the hydraulic pipeline 100 are spirally wound together. The second traction member 340 can be used to enhance the strength and toughness of the hydraulic pipeline 100 and extend the service life of the hydraulic pipeline 100.

[0063] Specifically, the second traction member 340 and the hydraulic pipeline 100 are spirally wound together, so that the hydraulic pipeline 100 is not connected to the moving member 500, and the folding and unfolding of the second traction member 340 can drive the hydraulic pipeline 100 to fold and unfold. Reducing the connection points on the outer peripheral side of the hydraulic pipeline 100 is equivalent to reducing the fatigue bending points on the hydraulic pipeline 100, further providing protection for the hydraulic pipeline 100.

[0064] In a possible implementation manner, the length of the second traction member 340 is smaller than the length of the hydraulic pipeline 100 .

[0065] In the above embodiment, when the telescopic member 200 moves in the opposite direction shown in the X direction, the second traction member 340 will drive the movable members 500 to slide, and the second traction member 340 will drive the hydraulic pipeline 100 to unfold. The length of the second traction member 340 is less than the length of the hydraulic pipeline 100. When the second traction member 340 is fully unfolded, the hydraulic pipeline 100 still has a certain amount of mobility. It can be understood that at this time, the hydraulic pipeline 100 is not subject to the pulling force from the telescopic member 200, which can further protect the hydraulic pipeline 100.

[0066] In a possible implementation manner, the first traction member 330 and the second traction member 340 are both steel wire ropes.

[0067] In the above embodiment, the steel wire rope has extremely high tensile strength, can withstand heavy loads and long-term use, and is suitable for various occasions requiring traction. The use of the steel wire rope as the first traction member 330 and the second traction member 340 can keep the first traction member 330 and the second traction member 340 stable during operation and not prone to severe vibration, which helps to improve the stability of the hydraulic pipeline 100. At the same time, the steel wire rope structure is relatively simple, and subsequent maintenance and replacement are relatively easy, which can reduce costs.

[0068] In one possible implementation, continue to refer to Figure 1 As shown, the hydraulic pipeline towing device also includes a limit assembly 600 , which is disposed on the line-laying platform 400 . The limit assembly 600 is located between the line-laying platform 400 and the telescopic member 200 . The limit assembly 600 is used to support the hydraulic pipeline 100 .

[0069] In the above embodiment, the limit assembly 600 is arranged between the wire-laying platform 400 and the telescopic member 200. The hydraulic pipeline 100 connected to the telescopic member 200 needs to pass through the limit assembly 600 and then abut against the wire-laying platform 400, which is equivalent to providing a hydraulic pipeline 100 on the wire-laying platform 400. The release and retraction opening supports and limits the movement range of the hydraulic pipeline 100, makes the hydraulic pipeline 100 stable, and reduces the adverse effects caused by vibration or shaking of the equipment body.

[0070] In a possible implementation, the limiting assembly 600 includes a limiting frame 610 and a roller 620 , and the limiting frame 610 is connected to the wire placing platform 400 .

[0071] The roller 620 is rotatably connected in the limiting frame 610, and specifically can be rotatably connected to the inner bottom wall of the limiting frame 610. The roller 620 is used to support the hydraulic pipeline 100. It can be understood that the top of the roller 620 is used to support the hydraulic pipeline 100.

[0072] In the above embodiment, the hydraulic pipeline 100 abuts against the roller 620 during the folding or unfolding process, which is equivalent to reducing the friction experienced by the hydraulic pipeline 100, so that the hydraulic pipeline 100 can be more easily moved to the wire placement platform 400 and folded, or more easily moved from the wire placement platform 400 to the side of the telescopic member 200.

[0073] In a possible embodiment, the hydraulic pipeline towing device further includes a baffle 700, which is disposed on the line placing platform 400, the baffle 700 is located on one side of the sliding direction of the moving member 500, and the baffle 700 is located between the reversing fixed pulley 310 and the telescopic member 200, and the length direction of the baffle 700 can be along Figure 1 Middle X direction setting.

[0074] In the above embodiment, when the hydraulic pipeline 100 is folded or unfolded on the wire-laying platform 400, the baffle 700 can prevent the hydraulic pipeline 100 from falling from the wire-laying platform 400, further avoiding interference between the hydraulic pipeline 100 and other components and affecting the normal operation of other components.

[0075] During specific implementation, the baffle 700 and the wire placement platform 400 are integrally formed, which helps to improve the strength and supporting stability of the wire placement platform 400 and the baffle 700.

[0076] In other possible implementations, the hydraulic pipeline towing device further includes a guide rail 800, which is used to be arranged on the device body, and the length direction of the guide rail 800 is along Figure 1 The moving members 500 are arranged in the X direction, and the moving members 500 are slidably connected to the guide rail 800 . The moving members 500 are arranged at intervals along the extending direction of the guide rail 800 .

[0077] Here, the guide rail 800 has the effect of a simple structure. On the one hand, it provides support for the moving member 500 , and on the other hand, it provides a limit for the sliding of the moving member 500 , so that the sliding of the moving member 500 is more stable.

[0078] In addition, the guide rail 800 has a simple structure and can reduce manufacturing costs.

[0079] Specifically, in order to facilitate the connection of the first traction member 330, a connection ear 501 is provided on the moving member 500 away from the reversing fixed pulley 310 to provide a connection position between the first traction member 330 and the moving member 500. The moving member 500 can be a moving trolley, and the specific structure and number of the moving trolley are not limited here, and can be selected according to needs and the structure of the internal space of the device body.

[0080] In a possible implementation, the pulley assembly 320 includes a first switching member 321 , a second switching member 322 , and a third switching member 323 .

[0081] The first pulling member 330 is connected to the bottom end of the telescopic member 200 , and the second pulling member 340 is connected to the top end of the telescopic member 200 .

[0082] The first switching member 321, the second switching member 322 and the third switching member 323 are all connected to the equipment body. The first switching member 321 is arranged below the telescopic member 200. Specifically, the first switching member 321 is located in the telescopic member 200 away from the direction indicated by the Z arrow. The second switching member 322 is arranged on one side of the first switching member 321. Specifically, the second switching member 322 is located in the first switching member 321 away from the direction indicated by the Y arrow. The third switching member 323 is arranged on one side of the moving member 500. Specifically, the third switching member 323 is located in the direction indicated by the Z arrow of the second switching member 322, so that the first traction member 330 is wound around the first switching member 321, the second switching member 322 and the third switching member 323 in sequence and then wound around the reversing fixed pulley 310, and the two ends of the first traction member 330 move in the same direction.

[0083] In the above embodiment, for example Figure 1 As shown, the first traction member 330 connected to the bottom end of the telescopic member 200 can be arranged horizontally in the XY plane after passing through the first reversing member 321, and then arranged vertically after passing through the second reversing member 322, and finally arranged horizontally after passing through the third reversing member 323, and then arranged around the reversing fixed pulley 310. In this way, the three-dimensional space can be fully utilized to achieve the same-direction movement of the two ends of the first traction member 330.

[0084] In addition, the first traction member 330 does not interfere with the movement of the moving member 500 , so that the telescopic member 200 can be moved below the guide rail 800 , so that the hydraulic pipeline 100 thereon can be more conveniently folded onto the line-laying platform 400 .

[0085] In another possible implementation, the first switching member 321, the second switching member 322 and the third switching member 323 are all fixed pulleys or fixed pulley groups, and their setting directions can be selected according to actual needs and are not limited here. Using fixed pulleys or fixed pulley groups to achieve the switching of the first traction member 330 has the effects of simple structure and low maintenance cost.

[0086] The implementation principle of a hydraulic pipeline towing device in an embodiment of the present application is as follows: the hydraulic pipeline towing device includes a towing assembly 300, a line-laying platform 400 and at least one moving part 500. The line-laying platform 400 and the towing assembly 300 are used to be arranged on the equipment body, and the moving part 500 is used to be slidably connected to the equipment body. The towing assembly 300 is configured to connect the telescopic member 200 with one of the moving parts 500, and drive each moving part 500 to slide in the same direction under the drive of the telescopic member 200. The line-laying platform 400 is used to place the hydraulic pipeline 100, and each moving part 500 is used to be connected to the hydraulic pipeline 100 to drive the hydraulic pipeline 100 to unfold or fold on the line-laying platform 400. By setting the towing assembly 300 and the moving part 500, the hydraulic pipeline 100 is unfolded or folded on the line-laying platform 400, which can avoid the hydraulic pipeline 100 from interfering with or even entangled with other parts during the working process, thereby avoiding affecting the normal operation of the equipment.
