The position of the first rotating arm 1 relative to the second rotating arm 2 is defined as "front"; the position of the inner rotating plate 32 relative to the outer rotating plate 31 is defined as "inner".

[0030] As described above, the wire running rotating arm is a mechanical device for protecting cables, wires, hoses and the like, such as Figure 6As shown, mainly used in the mobile occasions such as automation equipment, machine tools, robots, transport machinery, to protect the internal circuit from the outside mechanical impact, friction and chemical corrosion and other damage. The main role of the drag chain is to keep the line neat, safe and reliable, while allowing the line to freely stretch with the movement of the mechanical equipment.

[0031] However, the drag chain generally adopts special design and manufacturing process, complex structure, high cost; at the same time, the drag chain adopts multi-section structure, the side line is easy to wear, and the chain and the chain are easy to break, which shortens the service life; in addition, the drag chain adopts the special joint horizontal fixed mode, when the vertical direction is fixed, the bearing capacity is poor.

[0032] In order to at least solve one of the technical problems existing in the prior art or related art, the application provides a wire running rotary arm and coal car, which comprises: a first rotary arm, a second rotary arm and a connecting rotary plate, the first rotary arm and the second rotary arm are hinged through the connecting rotary plate; the first rotary arm comprises: a first wire pipe and a first connecting piece, the first connecting piece is arranged at the first end of the first wire pipe; the second rotary arm comprises: a second wire pipe and a second connecting piece, the second connecting piece is arranged at the first end of the second wire pipe; the connecting rotary plate comprises: an outer rotary plate connected with the second end of the first wire pipe; an inner rotary plate connected with the second end of the second wire pipe; the outer rotary plate and the inner rotary plate are hinged through a connecting shaft. The first rotary arm and the second rotary arm can drive the pipe to move back and forth, the application has the advantages of simple structure, convenient processing and manufacturing, and good bearing capacity; the angle of opening and closing of the first rotary arm and the second rotary arm is large, and the rotary arm material has high strength and is not easy to break.

[0033] The wire running rotary arm and coal car according to some embodiments provided by the application are described below with reference to the accompanying drawings.

[0034] Referring to Figures 1 to 5 , the application provides a wire running rotary arm, which comprises: a first rotary arm 1, a second rotary arm 2 and a connecting rotary plate 3, the first rotary arm 1 and the second rotary arm 2 are hinged through the connecting rotary plate 3; the first rotary arm 1 comprises: a first wire pipe 11 and a first connecting piece 12, the first connecting piece 12 is arranged at the first end of the first wire pipe 11; the second rotary arm 2 comprises: a second wire pipe 21 and a second connecting piece 22, the second connecting piece 22 is arranged at the first end of the second wire pipe 21; the connecting rotary plate 3 comprises: an outer rotary plate 31 connected with the second end of the first wire pipe 11; an inner rotary plate 32 connected with the second end of the second wire pipe 21; the outer rotary plate 31 and the inner rotary plate 32 are hinged through a connecting shaft 34.

[0035] The first rotating arm 1 is hinged to the vehicle body through the first connecting member 12, the second rotating arm 2 is hinged to the mobile container through the second connecting member 22, and the first rotating arm 1 and the second rotating arm 2 rotate around the connecting shaft 34 through the connecting rotating plate 3, so that the first rotating arm 1 and the second rotating arm 2 can approach or move away from each other. When the mobile container approaches the vehicle body, the first rotating arm 1 and the second rotating arm 2 approach each other; when the mobile container moves away from the vehicle body, the first rotating arm 1 and the second rotating arm 2 move away from each other. The larger the opening and closing angle of the first rotating arm and the second rotating arm, the more the pipeline can be driven to move back and forth. The pipeline enters the first threading pipe 11 from the vehicle body, passes through the connecting rotating plate 3, and then enters the second threading pipe 21, and finally is connected to the mobile container. The first threading pipe 11 and the second threading pipe 21 are made of steel pipes, which have high strength and rigidity and can effectively resist external impact, extrusion and wear, thereby protecting the internal pipeline from damage; at the same time, the steel pipe can provide stable support and has good load-bearing capacity.

[0036] In an exemplary embodiment, as shown in Figure 1 The inner rotating plate 32 is between the two outer rotating plates 31, and the wire guide plate 33 is arranged between the two inner rotating plates 32. The wire guide plate 33 and the two outer rotating plates 31 form a wire guide groove, which is used for turning the pipeline.

[0037] The outer rotating plate 31 is the main support structure; the inner rotating plate 32 and the wire guide plate 33 have a function similar to a wire roller, and the inner rotating plate 32 can rotate around the connecting shaft 34 in the outer rotating plate 31. The wire guide plate 33 is equivalent to the bottom of the wire guide groove, and the two outer rotating plates 31 are equivalent to the walls of the wire guide groove. The pipeline comes out of the first threading pipe 11, enters the wire guide groove, and then enters the second threading pipe 21 along the wire guide plate 33. This design can make the pipeline transition more smoothly when turning, reducing the risk of pipeline damage or loss of function caused by sharp turns; at the same time, the outer rotating plate 31, the inner rotating plate 32 and the wire guide plate 33 together form a solid protection structure, which can effectively protect the pipeline from external impact and wear.

[0038] In an exemplary embodiment, the outer rotating plate 31 is in the shape of a circular arc, and the inner rotating plate 32 is also in the shape of a circular arc. The diameter of the outer rotating plate 31 is larger than the diameter of the inner rotating plate 32. The outer rotating plate 31 and the inner rotating plate 32 are designed in the shape of a circular arc, which makes the pipeline transition more smoothly when turning, reducing the risk of pipeline damage or loss of function caused by sharp turns; at the same time, the circular arcs of the outer rotating plate 31 and the inner rotating plate 32 form a concentric structure, so that the inner rotating plate 32 and the outer rotating plate 31 will not affect the pipeline in the wire guide groove when rotating.

[0039] Further, the inner rotating plate 32 is provided with weight-reducing holes 38, which are evenly distributed along the circumference with the connecting shaft 34 as the center. For example, the weight-reducing holes 38 can be six in number and evenly distributed along the circumference. The weight-reducing holes 38 are specially designed holes in the inner rotating plate 32, which are used to reduce the overall weight of the component. The design of evenly distributing the weight-reducing holes 38 along the circumference helps to maintain the structural balance and strength of the component, while ensuring the maximization of the weight-reducing effect.

[0040] In an illustrative embodiment, as shown in Figure 2 and Figure 3 The two outer rotating plates 31 are provided with support plates 35, which are located near the first threading pipe 11. The two support plates 35 are located on the two sides of the outer rotating plates 31, which can enhance the structural stability of the two outer rotating plates 31, help to resist external forces or torques, and ensure that the two outer rotating plates 31 can maintain their preset positions and shapes under rotating or static conditions. At the same time, the support plates 35 also provide an additional guiding structure for the outlet of the first threading pipe 11, to ensure that the pipelines can be arranged according to the predetermined path.

[0041] In an illustrative embodiment, as shown in Figure 3 The two outer rotating plates 31 are provided with first struts 36, which are located near the first threading pipe 11. The first struts 36 are located on the outer sides of the two outer rotating plates 31, which enhances the connection strength between the two outer rotating plates 31, thereby improving the stability of the entire structure. At the same time, the first struts 36 also provide an additional guiding point for the outlet of the first threading pipe 11, to ensure that the pipelines can be arranged according to the predetermined path.

[0042] In an illustrative embodiment, as shown in Figure 5 The two inner rotating plates 32 are provided with second struts 37, which are located near the second threading pipe 21. The second struts 37 are located on the outer sides of the two inner rotating plates 32, which enhances the connection strength between the two inner rotating plates 32, thereby improving the stability of the entire structure. At the same time, the second struts 37 also provide an additional guiding point for the inlet of the second threading pipe 21, to ensure that the pipelines can be arranged according to the predetermined path.

[0043] In an illustrative embodiment, the first connecting member 12 includes: two first fixed plates 121, which are arranged on the two sides of the first end of the first threading pipe 11; and a first shaft sleeve 122, which is arranged between the two first fixed plates 121.

[0044] The first connecting member 12 is used to be hinged with the vehicle body. The combination of the two first fixing plates 121 and the first shaft sleeve 122 can form a relatively stable and easy-to-maintain structure, the first fixing plate 121 plays a role of supporting frame, providing a support structure for the whole component, and bearing various forces and moments generated by the hinged movement. The bearing is a mechanical element capable of supporting the shaft and allowing it to rotate relative to the shaft sleeve, and the arrangement of the first shaft sleeve 122 and the bearing enables the connecting part of the first connecting member 12 and the vehicle body to smoothly perform the hinged movement, while reducing the heat and wear caused by friction and prolonging the service life of the component. At the same time, the first fixing plate 121 is simple in structure and can be manufactured by conventional processing methods, which helps to reduce the cost.

[0045] Further, the first shaft sleeve 122 is not in the same straight line as the first wire-through pipe 11, and the position of the first shaft sleeve 122 needs to avoid the first end entrance of the first wire-through pipe 11 and leave enough space to accommodate the entry and movement of the pipeline. If the first shaft sleeve 122 is in the same straight line as the first wire-through pipe 11, it may hinder the smooth entry of the pipeline, easily leading to pipeline damage or installation difficulty.

[0046] In an illustrative embodiment, as shown in Figure 4 The first connecting member 12 further comprises a first roller 123 arranged between the two first fixing plates 121, and the first roller 123 is located on both sides close to the first end of the first wire-through pipe 11. The main role of the first roller 123 is to serve as a buffer and guide point between the pipeline and the first wire-through pipe 11, which can effectively prevent the pipeline from rubbing against the edge when passing through the first wire-through pipe 11, and can protect the integrity of the pipeline and prolong the service life of the pipeline.

[0047] In an illustrative embodiment, the second connecting member 22 comprises two second fixing plates 221 arranged on both sides of the first end of the second wire-through pipe 21, and a second shaft sleeve 222 arranged between the two second fixing plates 221. The second connecting member 22 is used to be hinged with the moving container, and the support structure composed of the two second fixing plates 221 and the second shaft sleeve 222 has the same effect as the combination of the two first fixing plates 121 and the first shaft sleeve 122, which will not be described here. It can be understood that, since the second fixing plate 221 is connected with different components than the first fixing plate 121, the shape of the second fixing plate 221 can be different from that of the first fixing plate 121.

[0048] In an illustrative embodiment, the second connecting member 22 further comprises a second roller 223 arranged between the two second fixing plates 221, and the second roller 223 is located on both sides close to the first end of the second wire-through pipe 21. The second roller 223 has the same effect as the first roller 123, which will not be described here.

[0049] In an illustrative embodiment, the first shaft sleeve 122 is provided with an angle sensor 4. The angle sensor 4 is used to detect the rotation angle of the first rotating arm 1. By measuring the rotation angle, the distance between the first rotating arm 1 and the second rotating arm 2 can be indirectly calculated through geometric calculation, under the condition that the initial positions, lengths and connection relationship between the first rotating arm 1 and the second rotating arm 2 are known. By monitoring the rotation angle of the first rotating arm 1 in real time through the angle sensor 4, the running state of the mobile box can be monitored, and adjustment or control can be performed as necessary, so as to ensure the stability and accuracy of the operation of the mobile box.
