Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 3 and 4, the towline operation support structure provided in this embodiment is used for supporting an overhead side towline 100, and includes:
a linear guide rail 1;
a first butt joint component 2 which can slide along the linear guide rail 1;
a rolling body 3 rotatably arranged on the first butt joint component 2, wherein the axial direction of the rolling body 3 is vertical to the extending direction of the linear guide rail 1; the rolling bodies 3 are used for supporting the part of the drag chain 100 on the overhead side during the operation of the drag chain 100;
a second docking assembly 4 for being disposed on the drag chain 100, the second docking assembly 4 being capable of being selectively engaged with and disengaged from the first docking assembly 2; when the second butt joint component 4 is combined with the first butt joint component 2, the second butt joint component 4 can drive the first butt joint component 2 to slide along the linear guide rail 1.
When the drag chain operation supporting structure provided by the embodiment is used, the second butt joint component 4 is arranged on the drag chain 100 close to the free end, the linear guide rail 1 is arranged on the overhead side of the drag chain 100, the extending direction of the linear guide rail 1 is parallel to the moving direction of the free end of the drag chain 100, and the first butt joint component 2 is positioned on the overhead side of the drag chain 100. The rolling bodies 3 of the first docking assembly 2 are able to support the drag chain 100 passing over them (the rolling bodies 3) during the movement of the moving end of the drag chain 100 on the overhead side, along the overhead side towards the stretching side.
After the first butt joint assembly 2 and the second butt joint assembly 4 interact and are combined, the rolling body 3 keeps a state of supporting the drag chain 100 thereon, and the relative position of the rolling body 3 and the drag chain 100 is basically unchanged, the second butt joint assembly 4 can drive the first butt joint assembly 2 and the rolling body 3 to slide along the linear guide rail 1 along with the moving end of the drag chain 100; when the first butt joint assembly 2 and the second butt joint assembly 4 are in a combined state, the rolling bodies 3 support the drag chain 100 on the rolling bodies, the collapse amount of the drag chain 100 on the overhead side can be obviously reduced, and on the premise that the plurality of roller supporting assemblies 200 support the extension side, the collapse amount of the drag chain 100 on the overhead side is reduced, so that the stroke on the overhead side is larger, and the maximum stroke of the drag chain 100 is correspondingly increased.
In addition, the towline operation support structure that this embodiment provided, under the prerequisite that satisfies towline 100 safe overhead operation, compare in prior art, can allow the partial length that towline 100 is located the overhead side longer, the total length of towline 100 is longer for the maximum stroke of towline 100 is bigger, can further satisfy bigger stroke demand.
It should be noted that when the drag chain 100 passes through the rolling element 3, the rolling friction force generated by the drag chain 100 and the rolling element 3 is not enough to make the first docking assembly 2 slide relative to the linear guide 1, in other words, an external force higher than the friction force between the drag chain 100 and the rolling element 3 is required to overcome the friction force between the first docking assembly 2 and the linear guide 1, so as to push the first docking assembly 2 to slide relative to the linear guide 1.
The second docking assembly 4 is positioned on the tow chain 100 near the free end, and optionally, to better prevent the tow chain 100 from collapsing on the overhead side, the second docking assembly 4 may be spaced from the free end of the tow chain 100 by about 1/4 the total length of the tow chain 100.
The rolling bodies 3 may be rollers or rollers.
In an alternative technical scheme, the first butt joint assembly 2 comprises a base matched with the linear guide rail 1 in a sliding mode and a connecting part arranged on the base, and the second butt joint assembly 4 comprises a base used for being connected with the drag chain 100 and a connecting part arranged on the base; the connecting part in the second butt joint component 4 is used for being combined with and separated from the connecting part in the first butt joint component 2; referring to fig. 3 to 5, in the connection portion of the first docking assembly 2 and the connection portion of the second docking assembly 4:
the connecting part comprises a first swing arm 5 arranged on the corresponding base and a first balance assembly 6 for balancing the position of the first swing arm 5, and the first swing arm 5 can swing back and forth along a first direction under the action of external force; the other connecting part comprises two swing arm assemblies 7 arranged on the corresponding base, each swing arm assembly 7 comprises a second swing arm 71 and a second balance assembly 72 for balancing the position of the second swing arm 71, wherein the two second swing arms 71 are arranged at intervals along the first direction;
the first direction is parallel to the extending direction of the linear guide rail 1;
each second swing arm 71 can only swing to one side facing to the other second swing arm 71 from the initial position under the pushing of the first swing arm 5, and the acting force of the first balance assembly 6 is greater than that of the second balance assembly 72;
when the two connecting portions are combined, the first swing arm 5 is located between the two second swing arms 71.
In an alternative embodiment, with reference to fig. 3, the first balance assembly 6 includes a connecting bar 61 and two elastic members 62, the connecting bar 61 is pivotally connected to the first swing arm 5 and includes two portions located at two sides of the first swing arm 5 along a first direction;
along the first direction, two sides of the first swing arm 5 are respectively provided with an elastic piece 62; each elastic member 62 has one end connected to a corresponding end of the connecting strip 61 and the other end connected to the base;
the first swing arm 5 extends along the direction of the base towards the second docking assembly 4 when in a balanced state under the action of the first balancing assembly 6. The elastic member 62 may be a spring.
Referring to fig. 5-7, in one embodiment, the first swing arm 5 can be pivoted to the corresponding base, and the connecting bar 61 can be pivoted to a side of the first swing arm 5 near the fixed end of the drag chain 100. Specifically, the base that sets up first swing arm 5 includes the body and sets firmly on the body, is used for setting up the mounting panel of first swing arm 5, and the one end that first swing arm 5 is used for being connected with the mounting panel is equipped with the through-hole, and the round pin axle passes the through-hole of first swing arm 5, and both ends are connected with the antifriction bearing in the support to set up first swing arm 5 on the base.
In order to enable the force of the first balance assembly 6 acting on the first swing arm 5 to be adjusted, so that the towchain running support structure provided by the embodiment can be suitable for towchains 100 with different specifications, optionally, the relative position of one end of the elastic piece 62 connected with the base and the base can be adjusted along the first direction. For example: the base comprises a body 211 and an adjusting plate 212, the body 211 is in sliding fit with the linear guide rail 1, the adjusting plate 212 is connected with the body 211 through bolts, and the elastic piece 62 is connected to the adjusting plate 212; an oblong hole 213 for mounting a bolt is provided in the adjustment plate 212, and the longitudinal direction of the oblong hole 213 is parallel to the first direction. At this time, the relative position of the adjustment plate 212 and the body 211 in the first direction is changed, i.e., the force of the first balance assembly 6 acting on the first swing arm 5 can be adjusted. Specifically, the body 211 may include a sliding block 300 slidably disposed on the linear guide 1 and a bottom plate fixedly disposed on the sliding block 300, and the adjusting plate 212 is disposed on a side of the bottom plate facing away from the sliding block 300.
When the tension of the springs at the two sides of the first swing arm 5 needs to be adjusted, the adjusting plate 212 is moved by loosening the bolts, and the tension of the springs at the two sides of the first swing arm 5 is kept consistent, so that the first swing arm 5 is kept at a vertical position, as shown in fig. 5; the adjustment criteria for the spring tension are as follows:
as shown in fig. 9, when the first swing arm 5 contacts the second swing arm 71, the force of the torsion spring received by the second swing arm 71 can be overcome, and the second swing arm 71 close to the second swing arm is pushed down and gets over, and finally gets between the two second swing arms 71.
As shown in fig. 3, when the first swing arm 5 is located between the two second swing arms 71, and the drag chain 100 moves, the second docking assembly 4 drives the first docking assembly 2 and the rolling element 3 to move along the linear guide 1 through the first swing arm 5.
In an alternative solution, the second balance assembly 72 includes a limiting member 721 located on a side of the corresponding second swing arm 71 away from the other second swing arm 71 and an elastic support member 722 located on a side of the corresponding second swing arm 71 toward the other second swing arm 71, and under the action of the elastic support member 722, the corresponding second swing arm 71 always has a tendency to rotate in a direction away from the other second swing arm 71.
Specifically, the elastic support 722 may include a torsion spring, and the limiting member 721 may include a limiting block, a limiting post, a limiting plate, or the like.
In a specific implementation manner, the second swing arm 71 is mounted on the base through a pin and a torsion spring, and finally integrally mounted on the corresponding drag chain 100 or the linear guide 1. After the installation is completed, the second swing arm 71 is in a vertical state when in a free state, when the second swing arm 71 is acted by an external force, the second swing arm 71 can swing towards the inner side (namely, the side where the other second swing arm 71 is located), and when the external force is cancelled, the second swing arm 71 restores to the vertical state due to the existence of the torsion spring. The second swing arm 71 is restricted from swinging to the outside (i.e., the side away from the other second swing arm 71) by the stopper 721.
Generally, the thickness of the drag chain 100 is limited, and the space for installing other structures is small, so that, as an alternative solution, the connecting portion of the first docking assembly 2 comprises the first swing arm 5 and the first balance assembly 6, and the connecting portion of the second docking assembly 4 comprises two swing arm assemblies 7 with relatively small occupation, so as to facilitate the arrangement of the structures.
Optionally, the tow chain running support structure comprises two stop assemblies 8, the two stop assemblies 8 being adapted to define the stroke of the first docking assembly 2, in particular the stop assemblies 8 may be bumpers, each defining one end of the stroke of the first docking assembly 2.
The drag chain device provided by the embodiment comprises the drag chain 100 and the drag chain operation supporting structure, so that the technical effect which can be achieved by the drag chain operation supporting structure can be at least achieved, that is, the maximum stroke of the drag chain 100 is larger, and the details are not repeated herein.
The operation of the drag chain device provided by this embodiment will be described with reference to fig. 8-10 by taking the example that the connecting portion of the first docking assembly 2 includes the first swing arm 5 and the first balance assembly 6, and the connecting portion of the second docking assembly 4 includes the two swing arm assemblies 7:
when the moving end of the drag chain 100 moves from the leftmost side to the right side on the overhead side, the first docking assembly 2 is placed on the leftmost side of the linear guide rail 1; as shown in fig. 8, in the initial state, the drag chain 100 is in the position of the state a, the second docking assembly 4 on the drag chain 100 is not in contact with the first swing arm 5, and the rolling body 3 supports the drag chain 100 when the free end of the drag chain 100 continues moving to the right. When the moving end of the drag chain 100 moves to the state b, as shown in fig. 9, the second swing arm 71 on the right side of the drag chain 100 contacts with the first swing arm 5, at this time, the rolling element 3 is about the middle position of the drag chain 100 on the overhead side, and when the drag chain 100 moves to the right again, the first swing arm 5 pushes the second swing arm 71 on the right side to swing and pass over the second swing arm 71, so as to be located in the middle of the two second swing arms 71; when the moving end of the drag chain 100 continues to move rightward, the second swing arm 71 drives the first swing arm 5, so as to drive the first docking assembly 2 and the rolling element 3 to move rightward together. At this time, if the moving end of the drag chain 100 stops moving to the right and moves to the left instead, the second swing arm 71 on the right side can also drive the first swing arm 5 to move to the left. When the drag chain 100 drives the rolling element 3 to move to the state c (i.e. the rolling element 3 is in contact with the bumper), as shown in fig. 10, because the bumper blocks the rolling element 3, the left second swing arm 71 pushes the first swing arm 5, so that the first swing arm 5 is pulled out from between the two second swing arms 71, and the drag chain 100 continues to move forward to the position of the state d. The first butt joint assembly 2 stops at the rightmost side of the linear guide rail 1, and the first swing arm 5 is restored to a vertical state.
When the moving end of the tow chain 100 travels from the rightmost side to the leftmost side: i.e. from state d to state a, the whole operation process is reversed to the above process. That is, the second swing arm 71 on the drag chain 100 drives the first docking assembly 2 to move from right to left through the first swing arm 5, and when the left buffer is reached, the first swing arm 5 is separated from between the two second swing arms 71, and the drag chain 100 continues to move forward. The first docking assembly 2 stops at the leftmost side of the linear guide 1, and the first swing arm 5 is restored to the vertical state.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
