Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to an adaptive adjustment bracket for supporting high-voltage cables laid in a serpentine pattern. Background Technology

[0002] High-voltage power cables are often laid in a serpentine pattern to effectively mitigate stress and strain caused by thermal expansion and contraction, allowing the cable a certain degree of freedom during thermal expansion. High-voltage power cables are fixed to fixed equipment (supports) using clamps to control the axial force on the cable. During this process, the cable supports bear significant lateral forces, making them more susceptible to damage over long-term use.

[0003] Therefore, when laying cables in a serpentine manner, an adaptive cable support is needed to accommodate the large axial force caused by thermal expansion and contraction of the cable during use, and to automatically adjust the angle or direction of the support according to the strain of the cable, thereby reducing the rigid stress on the support and cable bracket through self-adjustment. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive adjustment bracket to solve the problem that current cable brackets do not have adaptive adjustment capabilities, resulting in a high damage rate.

[0005] This utility model provides an adaptive adjustment bracket, which includes:

[0006] Base;

[0007] A support arm, one end of which is rotatably connected to the base, the support arm being used to support at least a portion of the cable and rotating relative to the base when subjected to an external force exerted on the support arm by the cable;

[0008] An elastic torsion member is disposed at the rotational connection position between the base and the support arm. The elastic torsion member is used to drive the support arm to return to its original position after absorbing the external force applied to the support arm by the cable.

[0009] The base has a connected base plate and a first connecting part. The first connecting part has a first through hole. One end of the support arm has a second connecting part. The second connecting part has a second through hole. A rotating shaft passes through the first through hole and the second through hole to rotatably connect the support arm and the base. The elastic torsion member passes through the rotating shaft and is located in the first through hole and / or the second through hole. Both ends of the elastic torsion member are fixed to the first connecting part and the second connecting part, respectively.

[0010] The adaptive adjustment bracket described in this invention solves the defect of cable brackets that cannot automatically adjust. This adaptive adjustment bracket can automatically adjust its angle according to the direction of force on the cable, thereby adapting to the stress or instantaneous impact force generated by the thermal expansion and contraction of the cable. Furthermore, due to the action of the elastic torsion member inside the bracket, the bracket can adaptively and gradually return to its initial state after impact deformation. This adaptive adjustment bracket experiences relatively small forces, allowing for the design of lighter and simpler brackets based on smaller forces, resulting in a robust, durable, and long-lasting structure. The base plate is used to fix the base, and the support arm and base are rotatably connected together through a first connecting part and a second connecting part. The other end of the support arm is used to connect the cable. This structural design facilitates the actual installation of the adaptive adjustment bracket and expands its application range.

[0011] In a preferred embodiment of the present invention, the adaptive adjustment bracket further includes a rotating gear pair disposed between the base and the support arm. The rotating gear pair is used to limit the support arm during the rotation of the support arm relative to the base, thereby improving the load-bearing capacity of the adaptive adjustment bracket.

[0012] In a preferred embodiment of the present invention, the first connecting part includes a gear seat, the side wall of the gear seat is provided with external gear teeth, the second connecting part is provided with an installation gap, the two sides of the installation gap are formed with parallel upper clamping plates and lower clamping plates, the side wall of the installation gap is provided with internal gear teeth, the gear seat is disposed in the installation gap so that the first through hole on the gear seat and the second through hole on the clamping plate are opposite to each other, and the external gear teeth and the internal gear teeth mesh with each other.

[0013] In this embodiment, a specific structure of a first connecting part and a second connecting part is provided. The first connecting part is in the form of a gear seat, which is clamped between the upper and lower clamping plates of the second connecting part, thereby realizing the rotational engagement connection of the first connecting part and the second connecting part. The clamping method can improve the structural stability of the rotational connection position.

[0014] In a preferred embodiment of the present invention, the first connecting part is provided with an installation gap, and parallel upper and lower clamping plates are formed on both sides of the installation gap. Inner gear teeth are provided on the side wall of the installation gap. The second connecting part includes a gear seat, and outer gear teeth are provided on the side wall of the gear seat. The gear seat is disposed in the installation gap so that the first through hole on the clamping plate and the second through hole on the gear seat are opposite to each other, and the inner gear teeth and the outer gear teeth mesh with each other.

[0015] In this embodiment, another specific structure of the first connecting part and the second connecting part is provided, wherein the second connecting part adopts the form of a gear seat, and the gear seat is clamped between the upper clamping plate and the lower clamping plate of the first connecting part, thereby realizing the rotational engagement connection of the first connecting part and the second connecting part. The clamping method can improve the structural stability of the rotational connection position.

[0016] In a preferred embodiment of this utility model, the elastic torsion member is a torsion spring.

[0017] In this embodiment, a torsion spring, which is a relatively mature technology in the prior art, is used as the torsion elastic element. The structure is relatively simple and the cost is low.

[0018] In a preferred embodiment of the present invention, the torsion spring is disposed in the first through hole or the second through hole of the upper clamping plate, the gear seat is provided with a first spring positioning hole, the upper clamping plate is provided with a second spring positioning hole, and the two ends of the torsion spring are respectively disposed in the first spring positioning hole and the second spring positioning hole.

[0019] In this embodiment, corresponding spring positioning holes are provided on the gear seat and the upper clamping plate, so that the two ends of the torsion spring abut against the gear seat and the upper clamping plate respectively, thereby restricting the rotation of the support arm relative to the base and providing a certain rotational restoring force for the support arm.

[0020] In a preferred embodiment of the present invention, the rotating shaft and the lower clamping plate are connected together by a key and a keyway, and the rotating shaft includes a rotating shaft body and a positioning shoulder.

[0021] In this embodiment, the rotating shaft and the lower clamping plate are connected by a key connection, so that the rotating shaft cannot rotate relative to the support arm, and the two form an integral structure that rotates relative to the base; and the positioning shoulder can abut against the upper clamping plate to prevent the rotating shaft from falling out of the fixed through hole.

[0022] In a preferred embodiment of the present invention, the torsion spring is disposed in the first through hole or the second through hole of the upper clamping plate, the gear seat is provided with a first spring positioning hole, the positioning shoulder is provided with a second spring positioning hole, and the two ends of the torsion spring are respectively disposed in the first spring positioning hole and the second spring positioning hole.

[0023] In this embodiment, when the pivot and the support arm are connected by a key, the second spring positioning hole can be set on the positioning shoulder of the torsion spring. This setting method can improve the performance of the torsion spring compared to setting the second spring positioning hole on the clamping plate, thereby increasing the adaptive force that the adaptive adjustment bracket can bear.

[0024] In a preferred embodiment of this utility model, an adjusting plate is provided between the gear seat and the upper clamping plate, and between the gear seat and the lower clamping plate.

[0025] In this embodiment, in order to facilitate the processing of the installation gap, the thickness of the installation gap is usually greater than the thickness of the gear seat. Therefore, it is necessary to set an adjustment plate of corresponding thickness in the installation gap to adjust the gap between the upper clamping plate and the lower clamping plate, and at the same time avoid wear of the upper clamping plate and the lower clamping plate.

[0026] In a preferred embodiment of this utility model, a baffle is provided on the rotating shaft, and the positioning shoulder and the baffle abut against the upper end surface of the upper clamping plate and the lower end surface of the lower clamping plate, respectively.

[0027] In this embodiment, the baffle and the positioning shoulder can limit the two ends of the rotating shaft, thereby axially positioning the rotating shaft and preventing it from falling out of the first through hole and the second through hole. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] like Figures 1 to 7 As shown, this utility model provides an adaptive adjustment bracket, comprising: a base 10; a support arm 20, one end of which is rotatably connected to the base 10, the support arm 20 being used to support at least a portion of a cable and rotating relative to the base 10 when subjected to an external force applied by the cable; an elastic torsion member disposed at the rotatable connection between the base 10 and the support arm 20, the elastic torsion member being used to drive the support arm 20 back to its original position after absorbing the external force applied by the cable; and a rotating gear pair disposed between the base 10 and the support arm 20, the rotating gear pair being used to adjust the position of the support arm 20 relative to the cable. During the rotation of the base 10, the support arm 20 is limited to improve the load-bearing capacity of the adaptive adjustment bracket. The base 10 has a connected base plate 11 and a first connecting part. The first connecting part is provided with a first through hole 13. One end of the support arm 20 forms a second connecting part. The second connecting part is provided with a second through hole 24. A rotating shaft 40 passes through the first through hole 13 and the second through hole 24 to rotatably connect the support arm 20 and the base 10. An elastic torsion member passes through the rotating shaft 40 and is located in the first through hole 13 and / or the second through hole 24. The two ends of the elastic torsion member are fixed to the first connecting part and the second connecting part, respectively.

[0047] The adaptive adjustment bracket described in this invention solves the defect of cable brackets that cannot automatically adjust. This adaptive adjustment bracket can automatically adjust its angle according to the direction of force on the cable, thereby adapting to the stress or instantaneous impact force generated by the thermal expansion and contraction of the cable. In addition, due to the action of the elastic torsion member inside the bracket, the bracket can adaptively and gradually return to its initial state after impact deformation. This adaptive adjustment bracket has a smaller force, and when designing the cable support structure, a lighter and simpler bracket can be designed based on the smaller force, which is sturdy, durable, and has a long service life.

[0048] It should be noted that the adaptive adjustment bracket described in this utility model is designed for cables and can provide movable support for cables laid in a serpentine manner. That is, the bracket designed in this application can be used in the field of cable laying technology, but is not limited thereto. The adaptive adjustment bracket can also be used in other technical fields that require movable support.

[0049] The following section will provide a detailed description of the specific structure of each part of the adaptive adjustment bracket described in this utility model and the connection relationship between them.

[0050] First, such as Figures 1 to 6As shown, the base 10 has a connected base plate 11 and a first connecting portion, and one end of the support arm 20 forms a second connecting portion. The base 10 and the support arm 20 are rotatably connected together through the first connecting portion and the second connecting portion. The specific structures of the first connecting portion and the second connecting portion can be interchanged. That is, the first connecting portion can be in the form of a gear seat 12, while the second connecting portion can be in the form of an upper clamping plate 21 and a lower clamping plate 22 with an installation gap 23; or, the second connecting portion can be in the form of a gear seat 12, while the first connecting portion can be in the form of an upper clamping plate 21 and a lower clamping plate 22 with an installation gap 23.

[0051] The two embodiments described above are not substantially different; both employ the same technical principle to achieve a rotatable connection between the base 10 and the support arm 20. For ease of explanation, the following description will use the example of a gear seat 12 as the first connecting part and an installation gap 23 as the second connecting part (e.g., Figures 1 to 6 (as shown); Since another implementation is essentially the same as this embodiment, except that the structural forms of the two connecting parts are changed, the other implementation will not be described in detail.

[0052] like Figure 3 and Figure 4 As shown, the base 10 is a fixing component, which has a connected base plate 11 and a first connecting part. The base plate 11 is used to fix the base 10, and the first connecting part is used to connect with the second connecting part on the support arm 20. In this embodiment, the base plate 11 is a rectangular steel plate, which can be fixed to the wall by welding or bolting. The first connecting part is a gear seat 12, which is a semi-circular steel plate that is perpendicular to the base plate 11 and is connected to the base plate 11 by welding.

[0053] Specifically, such as Figure 4 As shown, the side of the gear seat 12 away from the base plate 11 is a semi-circular structure, with a first through hole 13 at its center, and outer gear teeth are formed on the side wall of the semi-circular structure.

[0054] like Figure 5 and Figure 6 As shown, the support arm 20 is a movable part, which is a long strip of steel. One end of the support arm 20 has a second connecting part and is rotatably connected to the first connecting part (gear seat 12) through the second connecting part.

[0055] Specifically, such as Figure 5 and Figure 6As shown, a mounting gap 23 is provided at one end of the support arm 20. Parallel upper clamping plates 21 and 22 are formed on both sides of the mounting gap 23. The sidewall of the mounting gap 23 is an arc-shaped side, the radius of which is the same as the radius of the semi-circular structure on the upper part of the gear seat 12. An inner gear tooth capable of meshing with the outer gear tooth is provided on this arc-shaped sidewall; that is, the inner gear tooth and the outer gear tooth have the same module and tooth profile. The upper clamping plate 21 and the lower clamping plate 22 are vertically opposite each other, and a second through hole 24 is provided on them, penetrating both the upper clamping plate 21 and the lower clamping plate 22. The second through hole 24 is located at the center of the arc-shaped sidewall.

[0056] like Figure 5 As shown, the support arm 20 is also provided with multiple positioning holes 25, through which the cable can be tied to the support arm 20, thereby fixing the cable.

[0057] The base 10 and the support arm 20 are connected by a rotating shaft 40. During assembly, the upper clamping plate 21 and the lower clamping plate 22 on the support arm 20 clamp the gear seat 12 on the base 10, and adjust it so that the axes of the first through hole 13 and the second through hole 24 coincide. At this time, the outer gear teeth on the gear seat 12 mesh with the inner gear teeth on the mounting gap 23. Then, the rotating shaft 40 passes through the first through hole 13 and the second through hole 24, thereby connecting the base 10 and the support arm 20 together. The outer gear teeth on the gear seat 12 and the inner gear teeth on the mounting gap 23 form a rotating gear pair. The rotating gear pair can play an auxiliary positioning role in the installation process of the self-adjusting bracket, and can also limit the support arm 20 during the rotation of the support arm 20 relative to the base 10, so as to improve the load-bearing capacity of the self-adjusting bracket.

[0058] The rotating shaft 40 includes a rotating shaft body and a positioning shoulder 41. The rotating shaft body passes through the first through hole 13 and the second through hole 24, and the positioning shoulder 41 abuts against the upper end surface of the upper clamping plate 21, thereby preventing the rotating shaft 40 from falling out of the first through hole 13 and the second through hole 24.

[0059] Furthermore, such as Figure 2 As shown, in order to provide an elastic restoring force between the base 10 and the support arm 20, an elastic torsion member is also provided between the base 10 and the support arm 20. The elastic torsion member passes through the rotating shaft 40 and is located in the first through hole 13 and / or the second through hole 24, and the two ends of the elastic torsion member are respectively fixed to the first connecting part and the second connecting part. In this embodiment, the elastic torsion member adopts a torsion spring 30. The torsion spring 30 is technically mature, has a simple structure, and low cost.

[0060] Specifically, such as Figure 2 , Figure 4 and Figure 6As shown, the torsion spring 30 is disposed in the second through hole 24 of the upper clamping plate 21, and the upper end face of the gear seat 12 is provided with a first spring positioning hole 31, which is located at the edge of the first through hole 13; the upper clamping plate 21 is provided with a second spring positioning hole 32 (not shown in the figure), and the second positioning spring positioning hole 25 is located at the edge of the second through hole 24. The two ends of the torsion spring 30 are respectively disposed in the first spring positioning hole 31 and the second spring positioning hole 32.

[0061] During installation, before inserting the rotating shaft 40 into the first through hole 13 and the second through hole 24, the torsion spring 30 is placed in the second through hole 24 of the upper clamping plate 21. Simultaneously, both ends of the torsion spring 30 are fixed to the base 10 and the support arm 20 respectively through the first spring positioning hole 31 and the second spring positioning hole 32. This allows the torsion spring 30 to generate a corresponding torsional elastic restoring force between the base 10 and the support arm 20. The axis of the torsion spring 30 coincides with the axis of the first through hole 13. Then, the rotating shaft 40 is installed, passing through the torsion spring 30.

[0062] Better, such as Figure 6 As shown, the second through hole 24 on the upper clamping plate 21 is a stepped hole, with the diameters at the upper and lower ends being larger than the diameter in the middle, which facilitates the installation and positioning of the torsion spring 30.

[0063] The structure and technical effects of the preferred embodiment of the adaptive adjustment support of this utility model will be further described below.

[0064] According to one embodiment of the present invention, such as Figures 1 to 7 As shown, the rotating shaft 40 and the lower clamping plate 22 are connected together by the key 50 and the keyway 51. The rotating shaft 40 and the lower clamping plate 22 are connected together by the key 50, so that the rotating shaft 40 cannot rotate relative to the support arm 20. The two form an integral structure and rotate relative to the base 10.

[0065] Specifically, a keyway 51 is provided on the inner wall of the second through hole 24 on the lower clamping plate 22, and a keyway 51 is also provided on the corresponding position of the rotating shaft body. A flat key 50 is locked in the corresponding two keyways 51, thereby restricting the relative rotation between the rotating shaft 40 and the support arm 20.

[0066] Furthermore, such as Figure 2 and Figure 7As shown, the second spring positioning hole 32 is provided on the lower end face of the positioning shoulder 41. When the rotating shaft 40 and the support arm 20 are connected together by the key 50, the second spring positioning hole 32 can be provided on the positioning shoulder 41 of the torsion spring 30. This provisioning method can improve the performance of the torsion spring 30 and thus improve the adaptive force that the adaptive adjustment bracket can bear, compared with the embodiment in which the second spring positioning hole 25 is provided on the upper clamping plate 21.

[0067] According to one embodiment of the present invention, such as Figure 2 and Figure 6 As shown, adjusting plates 26 are provided between the gear seat 12 and the upper clamping plate 21, and between the gear seat 12 and the lower clamping plate 22.

[0068] To facilitate the machining of the mounting gap 23, the width of the mounting gap 23 is usually greater than the thickness of the gear seat 12. Therefore, an adjusting plate 26 of a certain thickness needs to be installed within the mounting gap 23 to adjust the gap between the upper clamping plate 21 and the lower clamping plate 22, while also preventing wear on the upper clamping plate 21 and the lower clamping plate 22. The adjusting plate 26 is a thin steel plate of a certain thickness, which is fixed to the upper clamping plate 21 and the lower clamping plate 22 by welding.

[0069] In a preferred embodiment of this utility model, such as Figure 2 and Figure 7 As shown, a baffle 42 is mounted on the rotating shaft 40, and the positioning shoulder 41 and the baffle 42 abut against the upper end surface of the upper clamping plate 21 and the lower end surface of the lower clamping plate 22, respectively. The baffle 42 and the positioning shoulder 41 can limit the two ends of the rotating shaft 40, thereby realizing the axial positioning of the rotating shaft 40 and preventing it from falling out of the first through hole 13 and the second through hole 24.

[0070] Better, such as Figure 2 As shown, the baffle 42 is fixed to the lower end face of the lower clamping plate 22 by screws, thereby preventing the baffle 42 from falling off.

[0071] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
