A cable adaptive servo device

Abstract

This invention relates to a cable adaptive follow-up device, comprising a base frame, a slant frame, a mounting bracket, a guide rail, and a sliding member. The slant frame is mounted on the top of the base frame, and the top plane of the slant frame forms an angle with the horizontal plane. The mounting bracket is mounted on the top of the slant frame, and the guide rail is mounted on the lower end face of the mounting bracket. The sliding member is slidably connected to the guide rail and slides along the downhill direction of the slant frame under its own weight. The sliding member is used to mount the cable. The beneficial effects are: during the operation of a reciprocating mobile device, when the device moves away from the device, it pulls the cable out; when the device moves closer to the device, the sliding member slides automatically along the downhill direction of the slant frame under its own weight, without external power. This structural design can adapt to changes in cable tension and achieve automatic reset, while also facilitating transportation and on-site assembly.

Description

Technical Field

[0001] This invention relates to the field of cable installation equipment technology, specifically a cable adaptive follow-up device. Background Technology

[0002] In the field of industrial automation, the servo management of cables that provide power and signals to reciprocating mobile devices is crucial to ensuring the long-term stable operation of the equipment.

[0003] Existing technologies mainly rely on cable drag chains, reels, and various conductor rail systems. However, these solutions reveal significant shortcomings under complex working conditions: traditional integral cable drag chains or conductor rails are cumbersome to install and difficult to transport, especially in space-constrained environments such as underground mines and tunnels. For long-stroke reciprocating motion, simple flexible dragging can easily lead to cable friction damage with the ground, while motor-driven active reels, although capable of winding and unwinding, are structurally complex, costly, require additional power and control, and have a relatively high failure rate.

[0004] Furthermore, during the deployment and retrieval of cables for devices such as drones, a mismatch between the deployment / retrieval speed and the device's movement can easily lead to cable tangling and knotting. Existing devices still have significant room for improvement in terms of multi-cable integrated management, impact resistance, anti-deviation, and automatic precise reset. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a cable adaptive follow-up device.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a cable adaptive follow-up device, comprising a base frame, a slant frame, a mounting frame, a guide rail, and a sliding component; The top of the base frame is equipped with a slanted frame, and there is an angle between the top plane of the slanted frame and the horizontal plane; The mounting bracket is installed on the top of the inclined frame, and the guide rail is installed on the lower end face of the mounting bracket. The sliding member is slidably connected to the guide rail, and the sliding member slides along the downhill direction of the inclined frame under its own weight. The sliding element is used to install cables.

[0007] As a further technical solution, the sliding member includes a support frame, a support base, a mounting plate, a first roller, and a second roller; The support is mounted on the top surface of the support frame, the support is connected to the mounting plate, and the first roller and the second roller are mounted on the end of the mounting plate opposite to the support. The first roller is arranged along the width direction of the guide rail, and the second roller is arranged along the height direction of the guide rail; The support frame is used to install cables.

[0008] As a further technical solution, buffers are provided at both ends of the mounting plate, and the two buffers are arranged along the tilting direction of the inclined frame.

[0009] As a further technical solution, elastic limiting members are provided at both ends along the length direction of the guide rail, and the elastic limiting members and the buffer members share the same center line.

[0010] As a further technical solution, the support frame includes a U-shaped support body, a frame plate, pipe clamps, bolts, and partitions; The frame plate is fixedly installed along the height direction inside the opening of the U-shaped support body; The frame plate has a cavity, and several pipe clamps are installed in the cavity by bolts. Each adjacent pipe clamp is connected by a partition in the height direction. The pipe clamps have through holes for cables to pass through. The bottom of the bolt passes through the through hole of the pipe clamp and is fixed to the bottom of the U-shaped support body.

[0011] As a further technical solution, a through hole is formed on the partition, and the nut on the bolt is accommodated in the through hole.

[0012] As a further technical solution, at least two bolts are provided along the height direction of the U-shaped support body, and the bottom of the upper bolt is threadedly connected to the nut of the lower bolt.

[0013] As a further technical solution, the base frame is also equipped with the support frame for fixing the cable, and the support frame is located at the lower part of the sliding member and on the lower side of the inclined frame.

[0014] As a further technical solution, the base frame is provided with a reinforcing rod, and the reinforcing rod is arranged along the height direction of the base frame.

[0015] As a further technical solution, the guide rail is a C-groove guide rail.

[0016] The beneficial effects of this invention are: 1. The combined design of the inclined frame, mounting bracket, guide rail, sliding parts, etc., allows the mobile equipment that performs reciprocating motion to extend the cable when it moves away from the device during operation. When the equipment moves towards the device, it slides down the inclined frame by its own weight through the sliding parts, without the need for external power. This structural design can adapt to changes in cable tension and achieve automatic reset, while also facilitating transportation and on-site assembly. 2. The specific structural design of the sliding component enables the cable to follow the reciprocating motion of the equipment with low resistance, achieve precise automatic reset and long-term reliable operation, and has significant economic and practical advantages.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0021] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] Example 1 This embodiment provides a cable adaptive follow-up device, including a base frame 1, a slant frame 2, a mounting frame 3, a guide rail 4, and a sliding member 5; the slant frame 2 is mounted on the top of the base frame 1, and the top plane of the slant frame 2 forms an angle with the horizontal plane; the mounting frame 3 is mounted on the top of the slant frame 2, and the guide rail 4 is mounted on the lower end face of the mounting frame 3; the sliding member 5 is slidably connected to the guide rail 4, and the sliding member 5 slides along the downhill direction of the slant frame 2 under its own weight; the sliding member 5 is used to install cables.

[0023] For example, the base frame 1 is a U-shaped structure formed by connecting multiple rods via connectors, which greatly facilitates transportation and on-site installation. The lower part of the inclined frame 2 is connected to the base frame 1 via connectors, and the inclination angle of the upper inclined surface of the inclined frame 2 is set as needed, with the principle that the sliding component 5 automatically returns to the lower side of the inclined frame 2 under the action of gravity (i.e., during the process of the equipment moving towards the base frame 1).

[0024] Furthermore, the base frame 1 is provided with a reinforcing rod 11, and the reinforcing rod 11 is arranged along the height direction of the base frame 1 to connect the two sides of the U-shaped base frame 1. For example, the reinforcing rod 11 is cross-shaped, which improves the stability and load-bearing capacity of the base frame 1.

[0025] For example, the mounting bracket 3 is frame-shaped, reducing the overall weight of the device, and the mounting bracket 3 is fixed to the top of the inclined frame 2 by connectors on all four sides. For example, to improve the load-bearing capacity of the mounting bracket 3, several horizontal plates 31 are spaced apart along the width direction of the mounting bracket 3, and an intermediate plate 32 is provided along the length direction of the mounting bracket 3. The horizontal plates 31 pass through the intermediate plate 32 and are connected to the intermediate plate 32. For example, the intermediate plate 32 has holes or grooves (not labeled in the figure) that are adapted to the horizontal plates 31 to pass through, so that the horizontal plates 31 can be inserted into the holes or grooves, thereby improving the overall stability of the mounting bracket 3 and extending its service life.

[0026] For example, the guide rail 4 is a C-groove guide rail to prevent the roller from slipping and to provide the sliding member 5 with a low-friction, high-rigidity linear motion path. For example, the length direction of the guide rail 4 is consistent with the length direction of the mounting bracket 3.

[0027] In the specific implementation process, the sliding member 5 includes a support frame 51, a support 52, a mounting plate 53, a first roller 54, and a second roller 55; the support 52 is mounted on the top surface of the support frame 51, the support 52 is connected to the mounting plate 53, and the first roller 54 and the second roller 55 are mounted on the end of the mounting plate 53 opposite to the support 52; the first roller 54 is arranged along the width direction of the guide rail 4, and the second roller 55 is arranged along the height direction of the guide rail 4; the support frame 51 is used to install cables.

[0028] For example, the guide rails 4 are provided in two parallel configurations. Each guide rail 4 has a first roller 54, a second roller 55, a mounting plate 53, and a support 52. For instance, the mounting plate 53 has two first rollers 54 and two second rollers 55. The two first rollers 54 are located in the middle of the mounting plate 53, and the two second rollers 55 are located on either side of the mounting plate 53, with the two first rollers 54 positioned between the two second rollers 55. The two first rollers 54 engage with the inner surfaces of the corresponding guide rails 4, effectively resisting lateral cable tension and preventing the sliding member 5 from deviating or derailing. The two second rollers 55 contact the bearing surfaces of the corresponding guide rails 4, evenly distributing the load of the sliding member 5 and the cable. In other words, the design of the first rollers 54 and second rollers 55 significantly improves operational stability and resistance to eccentric loads. It should be noted that the opening of the C-groove guide rail faces downwards in this configuration.

[0029] Furthermore, both ends of the mounting plate 53 are provided with buffers 56, and the two buffers 56 are arranged along the inclined direction of the inclined frame 2 to reduce the noise during the operation of the sliding member 5 and protect the first roller 54, the second roller 55 and the guide rail 4; for example, the buffer 56 is an annular rubber ring and is arranged coaxially with the guide rail 4 to improve the buffering effect.

[0030] In this embodiment, the specific structural design of the sliding member 5 ensures the bending radius of the cable and prevents the cable from breaking during movement.

[0031] In the specific implementation process, elastic limiting members 41 are provided at both ends along the length direction of the guide rail 4, and the elastic limiting members 41 and the buffer member 56 share the same center line, so that when the sliding member 5 approaches the end of its stroke, the buffer member 56 contacts the elastic limiting member 41. At this time, the elastic limiting member 41 absorbs the kinetic energy of the sliding member 5 impacting it smoothly through compression deformation, thereby achieving flexible stopping and avoiding damage to the first roller 54, the second roller 55, the guide rail 4 and the cable connector caused by rigid impact.

[0032] For example, the elastic limiting member 41 is a rubber buffer block, and it can be fixed in the guide rail 4 by a mounting base (not labeled in the figure).

[0033] In the specific implementation process, the support frame 51 includes a U-shaped support body 511, a frame plate 512, pipe clamps 513, bolts 514, and spacers 515. The frame plate 512 is fixedly installed along the height direction inside the opening of the U-shaped support body 511. The frame plate 512 has a cavity, and several pipe clamps 513 are installed in the cavity by the bolts 514. Each adjacent pipe clamp 513 is connected by a spacer 515 in the height direction. The spacer 515 can improve the stability between the pipe clamps 513. For example, the spacer 515 has a through hole, and the nut on the bolt 514 is accommodated in the through hole, which has the function of separating the longitudinally adjacent pipe clamps 513 and improving the connection stability. The pipe clamp 513 has a through hole 513a for the cable to pass through. The bottom of the bolt 514 passes through the through hole of the pipe clamp 513 and is fixed to the bottom of the U-shaped support body 511.

[0034] It should be noted that the support 52 is fixedly installed at both ends of the upper opening of the U-shaped support body 511. For example, the support 52 is a double-ear support. The mounting plate 53 is inserted into the double ears of the support 52 and rotated through the pin, thereby improving the stability and torsional resistance of the support.

[0035] For example, the U-shaped support body 511 has a U-shaped longitudinal section (viewed from the perspective of the side with the lower slope and the higher height of the box).

[0036] For example, the two sides of the frame plate 512 are fixedly connected to the inner sidewall of the U-shaped support body 511 to improve the stability of the frame plate 512; for example, the frame plate 512 is formed by several support bars; to improve the stability of the pipe clamp 513, the frame plate 512 is provided with at least one crossbar 512a, and the crossbar 512a is arranged along the width direction of the frame plate 512. Furthermore, the crossbar 512a is located at the junction of two layers of pipe clamps 513 in the height direction, further improving the stability of the pipe clamp 513.

[0037] For example, the pipe clamp 513 is arranged in several rows, and each row is provided with several pipe clamps 513, the specific number of which depends on actual needs.

[0038] More specifically, the pipe clamp 513 includes an upper pipe clamp body and a lower pipe clamp body adapted to the upper pipe clamp body, such that the upper pipe clamp body and the lower pipe clamp body are assembled to form a through hole 513a for the cable to pass through. That is, the lower part of the upper pipe clamp body and the upper part of the lower pipe clamp body are both provided with arc-shaped notches (not labeled in the figure). The size of the through hole 513a is determined according to the thickness of the cable.

[0039] In this embodiment, the combined use of the pipe clamp 513, the partition 515, and the bolt 514 enables the device to quickly and reliably clamp cables of different quantities and diameters, allowing multiple cables to be managed uniformly and in an orderly manner.

[0040] In the specific implementation process, at least two bolts 514 are provided along the height direction of the U-shaped support body 511, and the bottom of the upper bolt 514 is threadedly connected to the nut of the lower bolt 514. For example, the nut of the bolt 514 has an internal threaded hole, which facilitates the insertion of the bottom of the upper bolt 514 into the internal threaded hole, so as to realize the connection of multiple bolts 514 in the height direction. It should be noted that, in the height direction, the bolt 514 located at the bottom of the frame plate 512 is fixedly inserted into the bottom of the frame plate 512.

[0041] In the specific implementation, the base frame 1 is also equipped with a support frame 51 (with the same structure as the aforementioned support frame, so it will not be described in detail), which is used to fix the cable. The support frame 51 is located at the lower part of the sliding member 5 and on the lower side of the inclined frame 2. That is, after the cable is fixed to the support frame 51 on the base frame 1, it passes through the support frame 51 on the sliding member 5. During the reciprocating movement of the equipment, the cable between the two support frames 51 is straightened (when the equipment moves away from the device) or bent (when the equipment moves closer to the device). For easy assembly and disassembly, the two sides of the support frame 51 are symmetrically provided with connecting plates 57, so that the support frame 51 is fixedly connected to the base frame 1 through the connecting plates 57 (such as screw connection).

[0042] This embodiment is implemented as follows: One end of the multiple cables that need to be moved is clamped and fixed on the support frame 51 (specifically, fixed on the pipe clamp 513) on the base frame 1, and the other end passes through the support frame 51 on the sliding member 5 and is connected to the external mobile device. When the mobile device moves away from the device, the sliding member 5 is pulled along the uphill direction of the inclined frame 2 by the cable. During this process, slight rolling friction resistance is overcome and the cable is released. When the mobile device moves closer to the device, the pulling force on the cable disappears. At this time, under the action of the cable's own gravity, the sliding member 5 and the cable automatically slide and reset along the guide rail 4 to the lower end. The elastic limiting members 41 at both ends of the guide rail 4 ensure that the reset process is smooth and without impact.

[0043] The structural design of this embodiment enables the cable to follow the equipment with low resistance, achieve precise automatic reset, and operate reliably for a long time during reciprocating motion, which has significant economic benefits and practicality.
