[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0061] Embodiments of the utility model will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the utility model, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used in all drawings to represent the same or similar parts. In addition, although the terms used in the utility model are selected from well-known and commonly used terms, some of the terms mentioned in the utility model specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description herein. In addition, it is required to understand the utility model not only by the actual terms used, but also by the meaning implied by each term.

[0062] As shown in Figure 1~ Figure 4 As shown, the utility model provides a double-headed drag chain floating head, comprising: an upper connecting member 100, a drag chain connecting member 200 and a horizontal sliding device 300.

[0063] The upper connecting member 100 includes a bottom plate 110, a connecting plate 130 and at least two side plates 120, the side plates 120 are connected to both sides of the bottom plate 110, the connecting plate 130 is installed between the bottom plate 110 and the side plates 120, the connecting plate 130 is fixedly connected to the connecting frame 400 of the trolley, and a height adjustment device 121 is provided on each side plate 120 for adjusting the position of the upper connecting member 100 and the connecting frame 400 of the trolley;

[0064] The horizontal sliding device 300 is installed on the lower end surface of the bottom plate 110;

[0065] The drag chain connector 200 includes a drag chain connecting plate 210 and at least two side connecting plates 220, one end of the side connecting plate 220 is connected to both sides of the drag chain connecting plate 210, and the other end of the side connecting plate 220 is connected to both sides of the horizontal sliding device 300, and is located below the bottom plate 110 of the upper connector 100;

[0066] The drag chain connector 200 slides along the bottom plate 110 through the horizontal sliding device 300;

[0067] The left and right sides of the drag chain connecting plate 210 each have at least one drag chain joint connecting portion 211 .

[0068] Since a height adjustment device 121 is provided on each side plate 120 , the relative height or the connection angle between the upper connecting member 100 and the connecting frame 400 of the trolley can be adjusted.

[0069] When the height adjustment devices 121 on the two side panels 120 are adjusted upward or downward by the same distance at the same time, the relative height between the upper connecting member 100 and the connecting frame 400 of the trolley changes, that is, Figure 3B and Figure 4 As shown in , the upper connecting member 100 translates along the Z-axis direction.

[0070] When the height adjustment device 121 on one of the side panels 120 is adjusted upward, and the height adjustment device 121 on the other side panel 120 is adjusted downward, the connection angle between the upper connecting member 100 and the connecting frame 400 of the trolley changes, that is, Figure 3B and Figure 4 As shown in , the upper connecting member 100 rotates around the Y axis, that is, rotates in the direction of arrow a.

[0071] The entire floating head is adjusted in height by adjusting the Z-direction translation of the upper connector 100, ensuring that the double-headed drag chain traction plate works at the height allowed by the drag chain 500. The Y-axis rotation adjustment allows the upper connector 100 to rotate in the direction of the drag chain operation, thereby ensuring that the drag chain 500 runs horizontally.

[0072] Since there is at least one drag chain joint connection part 211 on each of the left and right sides of the drag chain connecting plate 210, the two ends of a drag chain connecting plate 210 can be used to respectively fix the two fixed ends of the double-head drag chain, instead of using two floating heads to pull the double-head drag chain in the past, so as to achieve the purpose of reducing costs.

[0073] like Figure 3B As shown, as a preferred embodiment of the double-head drag chain floating head of the utility model, the height adjustment device 121 includes a height adjustment bolt 122 and a bolt connecting part 123, the bolt connecting part 123 is installed on the inner wall of the side panel 120, one end of the height adjustment bolt 122 is connected to the bolt connecting part 123, and the other end is connected to the connecting frame 400 of the trolley.

[0074] Preferably, the height adjustment bolt 122 cooperates with the threaded hole on the connecting frame 400 of the trolley, so that the relative height or the connection angle between the upper connecting member 100 and the connecting frame 400 of the trolley can be adjusted.

[0075] When the height adjustment bolts 122 on the two side plates 120 and the connection positions on the connecting frame 400 of the trolley are adjusted upward or downward by the same distance at the same time, the relative height of the upper connecting member 100 and the connecting frame 400 of the trolley changes, that is, Figure 3B and Figure 4 As shown in , the upper connecting member 100 translates along the Z-axis direction. .

[0076] When the height adjustment bolt 122 on one of the side panels 120 is adjusted upward to connect with the connecting frame 400 of the trolley, and the height adjustment bolt 122 on the other side panel 120 is adjusted downward to connect with the connecting frame 400 of the trolley, the connection angle between the upper connecting member 100 and the connecting frame 400 of the trolley is changed. Figure 3B and Figure 4 As shown in , the upper connecting member 100 rotates around the Y axis, that is, rotates in the direction of arrow a.

[0077] like Figure 4 , Figure 5 , Fig. 6A and Figure 6B As shown, as a preferred embodiment of the double-headed drag chain floating head of the utility model, at least two first oblong holes 131 are vertically arranged on the connecting plate 130, and the connecting plate 130 is fixedly connected to the connecting frame 400 of the trolley through the first oblong holes 131 and the first connecting bolts 132.

[0078] The first oblong hole 131 allows the position of the fixed connection between the connecting plate 130 and the connecting frame 400 of the trolley to be adjusted, so that the relative height or the connection angle between the upper connecting member 100 and the connecting frame 400 of the trolley can be adjusted in cooperation with the height adjustment bolt 122.

[0079] like Figure 5 , Fig. 6A and Figure 6B As shown, as a preferred embodiment of the double-headed drag chain floating head of the utility model, at least two second oblong holes 111 are arranged on the bottom plate 110 along the circumferential direction, and the horizontal sliding device 300 is connected to the bottom plate 110 through the second oblong holes 111 and the second connecting bolts 112.

[0080] Fig. 6A The middle dotted line shows a preferred arrangement of the second oblong hole 111 along the circumferential direction.

[0081] The second oblong hole 111 allows the connection position between the bottom plate 110 and the horizontal sliding device 300 to be adjusted. Figure 4 As shown in FIG. 1 , the horizontal sliding device 300 can rotate around the Z axis, that is, in the direction of arrow b.

[0082] By adjusting the Z-axis rotation, horizontal rotation adjustment can be achieved to avoid horizontal deflection of the drag chain 500.

[0083] like Figure 1B and Figure 4 As shown, as a preferred embodiment of the double-headed drag chain floating head of the utility model, the drag chain joint connecting portion 211 is provided with a slope 212 .

[0084] The design of the slope 212 allows the drag chain 500 to slide in or out more easily along the slope 212 when moving or installing. When the drag chain 500 encounters impact or vibration during movement, the slope 212 can serve as a buffer area to reduce the impact on the drag chain 500 and the drag chain joint.

[0085] like Figure 1A , Figure 1B and Figure 4 As shown, as a preferred embodiment of the double-headed drag chain floating head of the utility model, a horizontal roller device 213 is provided at the bottom of the drag chain connecting plate 210 .

[0086] The horizontal roller device 213 plays a guiding role, enabling the floating head of the double-headed drag chain to move along the drag chain guide groove 600 of the double-headed drag chain system.

[0087] like Figure 2AAs shown, as a preferred embodiment of the double-head drag chain floating head of the utility model, the horizontal sliding device 300 includes an optical axis 310, a linear bearing 320 and a bearing seat 330, the bearing seat 330 is fixedly connected to the base plate 110, the linear bearing 320 is arranged in the bearing seat 330, the two ends of the optical axis 310 are fixedly connected to the side connecting plate 220, and the optical axis 310 passes through the linear bearing 320 to achieve horizontal movement.

[0088] The linear bearing 320 is installed on the bearing seat 330 and fixed on the end cover 340. The optical axis 310 passes through the linear bearing 320 to achieve horizontal movement.

[0089] like Figure 2B As shown, as a preferred embodiment of the double-headed drag chain floating head of the utility model, a lubricating oil nozzle 331 is also provided on the bearing seat 330.

[0090] The lubricating nozzle 331 can ensure that the linear bearing 320 and the optical axis 310 are fully lubricated to avoid rust.

[0091] As described above, the floating head of the double-headed drag chain of the utility model uses a drag chain connecting plate 210 at both ends to fix the two fixed ends of the double-headed drag chain. The utility model adopts a horizontal sliding device 300 to solve the problem of inconsistent running directions of the floating head of the drag chain, the drag chain 500, the drag chain guide groove 600 and the trolley. The utility model adopts a horizontal roller device 213 to ensure that the double-headed drag chain runs in the guide groove.

[0092] The double-headed drag chain floating head of the utility model can rotate around the Z axis, so that the double-headed drag chain floating head can be adjusted for horizontal rotation; two vertical first oblong holes 131 are used with two vertical height adjustment devices 121, so that the floating head can be adjusted for translation along the Z axis and rotation around the Y axis. The impact of installation and manufacturing errors on the operation of the double-headed drag chain is solved, and the installation requirements specified in the drag chain manual are ensured to be met after the drag chain is installed.

[0093] The utility model aims at a double-head drag chain and designs a floating head which can simultaneously tow the double-head drag chain, replacing the previous situation of using two floating heads for towing, so as to achieve the purpose of reducing costs.

[0094] In order to adapt to the new environmental protection and production process requirements, the double-head drag chain floating head designed by the utility model has three degrees of freedom fine-tuning functions (ie, Z-direction translation, Y-axis rotation, and Z-axis rotation).

[0095] The double-headed drag chain floating head of the utility model can form a double-headed drag chain floating head system after being connected with the drag chain 500 and the drag chain guide groove 600. The double-headed drag chain system includes the drag chain 500, the drag chain guide groove 600 and the double-headed drag chain floating head as described above. The joint of the drag chain is connected to the double-headed drag chain floating head. The drag chain guide groove 600 is arranged at the lower part of the double-headed drag chain floating head. The drag chain 500 slides in the drag chain guide groove 600.

[0096] In summary, the double-head drag chain floating head of the utility model has the following advantages:

[0097] 1. The utility model designs a double-headed drag chain floating head for the double-headed drag chain, replacing the previous situation of using two floating heads to pull the double-headed drag chain, so as to achieve the purpose of cost reduction.

[0098] 2. The double-headed drag chain floating head of the utility model can adapt to the new manufacturing process, has strong adjustability and simple structure;

[0099] 3. The utility model reduces the installation difficulty of the entire drag chain floating head system, while ensuring the installation accuracy required for its operation.
