Description

Technical Field

[0001] The present application belongs to the field of cable protection of displacement mechanisms, and more specifically, to a cable support assembly and a displacement mechanism. Background Art

[0002] The displacement device is generally connected to a cable. When the displacement device moves, the cable moves with the displacement mechanism. In order to protect the cable, a drag chain is generally provided on the displacement mechanism, so that the cable is fixed on the drag chain and moves with the displacement device. However, the drag chain has a small hanging load capacity. When the drag chain is long, the drag chain is easily deformed and damaged under the weight of the drag chain and the cable.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] The present application provides a cable support assembly, which can support cables, and in particular, the cable support assembly can support cables on a displacement device.

[0040] like Figure 1 and Figure 2 As shown, a cable support assembly includes a guide member 100, a plurality of sliding structures 200, a connecting rope 300 and a support structure 400.

[0041] The plurality of sliding structures 200 are respectively disposed on the guide member 100 along the length direction of the guide member 100 , and the sliding structures 200 can move relative to the guide member 100 .

[0042] Every two adjacent sliding structures 200 are connected by a connecting rope 300. For example, when the two sliding structures 200 are close to each other, the connecting rope 300 between the two adjacent sliding structures 200 can be gradually bent, and when the two sliding structures 200 are away from each other, the connecting rope 300 between the two adjacent sliding structures 200 can be gradually stretched and finally straightened.

[0043] The support structures 400 are respectively disposed on the sliding structures 200, and the support structures 400 are respectively used to support cables (not shown in the figure). For example, when multiple support structures 400 cooperate to support a long cable, that is, when two support structures 400 are close to each other, the cable portion between the two adjacent support structures 400 can be gradually bent, and when the two support structures 400 are away from each other, the cable portion between the two adjacent support structures 400 can be gradually stretched.

[0044] It can be understood that by arranging multiple sliding structures 200 on the guide member 100, each sliding structure 200 is connected by a connecting rope 300. When one of the sliding structures 200 moves on the guide member 100, the connecting rope 300 can be bent or stretched. When the connecting rope 300 is bent, the previous sliding structure 200 moves to directly contact the adjacent next sliding structure 200 or indirectly contact the connecting rope 300 to drive the sliding structure 200 to move. When the connecting rope 300 is straightened, the previous sliding structure 200 can pull the adjacent next sliding structure 200 to move through the connecting rope 300 during the process of continuing to move.

[0045] That is to say, the movable cables can be placed respectively on the support structure 400 connected to each sliding structure 200. When the cables are moving, since the cables are supported by the support structure 400, the cables can drive the support structure 400 to move along the guide member 100 under the action of the corresponding sliding structure 200. During the movement, the connecting rope 300 between two adjacent sliding structures 200 can be bent or stretched, and the cable between two adjacent supporting structures 400 can also be bent or stretched. For example, when the connecting rope 300 is stretched, the previous sliding structure 200 can drive the next sliding structure 200 to move through the connecting rope 300, and the cable supported by the support structure 400 on the driven sliding structure 200 can also move.

[0046] Therefore, the cable support mechanism of the present application is capable of supporting movable cables, and the cables are supported by a support structure 400 connected by multiple sliding structures 200, and the sliding structure 200 is arranged on the guide member 100. The present application can support the cables by slidingly cooperating between the guide member 100 and the sliding structure 200 connected to the support structure 400. At the same time, the sliding structure 200 is also conducive to driving the cable to move, and the structure in which the sliding structure 200 and the guide member 100 slide relative to each other is not easily damaged.

[0047] In addition, the number of the sliding structures 200 and the supporting structures 400 can be set according to the length of the cable, so that the cable supporting assembly can support cables of different lengths.

[0048] In some embodiments, since the guide member 100 only serves to bear and guide the sliding structure 200 , the guide member 100 may be made of a material with good rigidity, such as metal, to further ensure the stability of the cable support assembly.

[0049] The connecting rope 300 may be a steel wire rope to improve the durability of the connecting rope 300 .

[0050] Furthermore, the length of the connecting rope 300 is shorter than the length of the cable portion between two adjacent supporting structures 400 to prevent the cable portion between the two supporting structures 400 from being straightened (pulled) to avoid damaging the cable.

[0051] It can be understood that since adjacent sliding structures 200 are connected by the connecting rope 300, when the displacement device drives the cable to move, the cable will first cause one of the sliding structures 200 (for example, the first sliding structure 200) to move on the guide member 100. When the sliding direction of the sliding structure 200 is away from the adjacent sliding structure 200, the connecting rope 300 can drive the adjacent sliding structure 200 to move only after the connecting rope 300 is straightened. Therefore, the length of the connecting rope 300 is less than the length of the cable portion between two adjacent support structures 400, which can cause the cable portion to be straightened before the connecting rope 300 is straightened.

[0052] See also Figure 3 The support structure 400 may include a support member 410 , which is disposed on the sliding structure 200 , and a support surface 420 for supporting the cable is also disposed on the support member 410 .

[0053] For example, the support member 410 may be disposed on the sliding structure 200 and extend in a direction away from the sliding structure 200 to form a support surface 420. The extending direction of the support member 410 may be perpendicular to the moving direction of the sliding structure 200.

[0054] It is understandable that since the length of the cable is generally long, in order to facilitate the cable support mechanism to support the cable, the support surface 420 of the support structure 400 set on each sliding structure 200 can be coordinated to support the cable, that is, the cable can be placed on the support surface 420.

[0055] For example, in some embodiments, when the cable support mechanism is located above the displacement device, the cable on the support surface 420 may be pressed against the support member 410 under the action of gravity, which can prevent the cable from moving on the support member 410.

[0056] Furthermore, the length of the cable portion reserved between two adjacent support structures 400 can be made longer than the length of the connecting rope 300 connected between two adjacent sliding structures 200, so as to avoid the cable being straightened.

[0057] See also Figure 3 A limiting member 430 may also be provided on the support member 410, and a first limiting groove 460 is formed between the limiting member 430 and the sliding structure 200. The first limiting groove 460 is used to limit the cable on the support member 410 to prevent the cable from detaching from the support member 410, that is, to prevent the cable from detaching from the support surface 420 of the support member 410.

[0058] For example, in some embodiments, the limiting member 430 may be disposed on a side of the supporting member 410 away from the sliding structure 200 , so that a first limiting groove 460 is formed between the limiting member 430 and the sliding structure 200 .

[0059] It can be understood that since multiple sliding structures 200 are arranged on the guide member 100 along the length direction of the guide member 100, the corresponding support structure 400 arranged on each sliding structure 200 is also distributed along the length direction of the guide member 100. Therefore, the first limiting groove 460 on each support structure 400 is also distributed along the length direction of the guide member 100. In this way, the cables can be conveniently placed in each first limiting groove 460 in sequence.

[0060] See also Figure 3 In some embodiments, a slope 440 is provided at the end of the support member 410 along the length direction of the guide member 100, and the slope 440 is inclined in a gradually downward direction.

[0061] It can be understood that when two adjacent support structures 400 are close to each other, the cable portion between the two adjacent support structures 400 can be bent, and the bent cable will naturally sag under the action of gravity. The cable will bend between the end of the support member 410 during the sagging process, so the inclined surface 440 can reduce the curvature of the cable bending and prevent the end of the support member 410 from producing a right angle to the cable and rubbing it.

[0062] Furthermore, a curved surface 450 may be provided at the end of the inclined surface 440 away from the support member 410 , and the curved surface 450 may prevent the end of the inclined surface 440 from generating a right angle to rub against the cable and damage the cable.

[0063] Combination Figure 1 and Figure 2 The sliding structure 200 may include a base 210, a first pulley 220 and a second pulley 230. The first pulley 220 and the second pulley 230 are relatively arranged on the base 210 and clamp the guide member 100, and the first pulley 220 and the second pulley 230 can move relative to the guide member 100, which makes the sliding structure 200 move on the guide member 100 more stable.

[0064] In some embodiments, the connecting rope 300 and the supporting structure 400 may be disposed on the base 210 .

[0065] For example, the support member 410 of the support structure 400 may be disposed on the base 210 .

[0066] In some embodiments, the support member 410 , the base 210 , the inclined surface 440 , and the stopper 430 may be integrally formed.

[0067] Furthermore, a second limiting groove 240 may be provided on the circumferential surface of the first pulley 220 and / or the second pulley 230 , and the guide member 100 is located in the second limiting groove 240 .

[0068] It is understandable that the second limiting groove 240 can prevent the first pulley 220 and / or the second pulley 230 from being separated from the guide member 100 , so that the first pulley 220 and / or the second pulley 230 can always move along the length direction of the guide member 100 .

[0069] Furthermore, a buffer member 250 may be provided on the base 210 , and the buffer member 250 is used to provide buffering when two adjacent bases 210 approach each other, so as to avoid rigid contact between the bases 210 .

[0070] For example, the buffer 250 on the base 210 may contact with the adjacent base 210 for buffering, or the buffer 250 on the base 210 may contact with the buffer 250 on the adjacent base 210 for buffering.

[0071] See also Figure 2 In order to facilitate the installation of the connecting rope 300 , a mounting member 500 may be further provided on the sliding structure 200 , one end of the connecting rope 300 is connected to one of two adjacent sliding structures 200 , and the other end of the connecting rope 300 is connected to the other sliding structure 200 .

[0072] For example, in some embodiments, the mounting member 500 may be disposed on the base 210 .

[0073] See also Figure 1 A stopper 600 may also be provided at the end of the guide member 100 , and the stopper 600 is used to stop the sliding structure 200 to prevent the sliding structure 200 from separating from the guide member 100 during the movement.

[0074] For example, the stopper 600 can stop the base 210 in the sliding structure 200 .

[0075] In addition, the present application also provides a displacement mechanism, including a displacement device and the cable support assembly in the above embodiment, wherein the displacement device can move relative to the guide member 100, and the displacement device is connected to a cable, and the cable is placed on the support structure 400. The displacement device can be a motion platform, for example, a linear motion platform.

[0076] Furthermore, in some embodiments, the cable support assembly may be located above the displacement device. In this way, on the one hand, the connecting rope 300 and the cable portion between two adjacent support structures 400 can have sufficient suspended space after being folded to avoid contact with the ground or other mechanisms of the processing equipment. On the other hand, it is beneficial for the cable to be pressed against the support structure 400. At the same time, when the displacement device drives the connected cable to move, the cable can drive the support structure 400 and the sliding structure 200 connected to the support structure 400 to move.

[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some applications should be included in the protection scope of some applications.
