DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] The embodiment of the first aspect of the present invention is to provide a cable auxiliary installation device, such as Figure 1 As shown, it includes a bracket assembly 2, a rotating pressing block 3, a fixed pressing block 4 and a limiting assembly 5;

[0040] The fixed pressing block 4 is fixedly mounted on the bracket assembly 2, and the rotating pressing block 3 is rotatably connected to the bracket assembly 2 and forms a clamping channel between the fixed pressing block 4 to allow the cable 6 to move upward in one direction;

[0041] The limit assembly 5 is connected to the rotating pressure block 3 and extends to the entrance of the clamping channel. The limit assembly 5 is configured to open the entrance of the clamping channel under the squeezing of the cable 6 and drive the rotating pressure block 3 to rotate relative to the bracket assembly 2 to expand the entrance. It is also configured to reset the blocked entrance when not subject to external force.

[0042] The cable auxiliary installation device can be fixed on an object to be installed with a cable when in use. The object can be, but is not limited to, an insulator body 1, a wall, etc. The following text takes the cable auxiliary installation device fixed on the insulator body 1 as an example for specific description:

[0043] like Figure 1 As shown, when installing the cable 6, the cable 6 is driven by the robot to squeeze the limit assembly 5, forcing the limit assembly 5 to open the entrance of the clamping channel. At the same time, the limit assembly 5 drives the rotating pressure block 3 to rotate counterclockwise relative to the bracket assembly 2 to expand the entrance of the clamping channel. When the cable 6 passes over the edge of the limit assembly 5 and enters the inside of the clamping channel, the rotating pressure block 3 and the fixed pressure block 4 clamp the cable 6 together, and the limit assembly 5 blocks the entrance of the clamping channel. Then the robot can drag the cable 6 upward, and the clamping channel allows the cable 6 to move upward to adjust the position of the cable relative to the insulator body. After the cable 6 reaches the position, the robot and the cable 6 are separated, and the clamping channel can prevent the cable from moving downward.

[0044] The cable auxiliary installation device provided in the embodiment of the first aspect of the present invention facilitates the robot to quickly and conveniently fix the cable 6 on the insulator body 1, and at the same time allows the robot to drag the cable 6 upward to adjust the position of the cable 6 relative to the insulator body 1. The cable 6 will not run out when moving upward in the clamping channel, and the cable 6 will not slide down after the robot releases the cable 6, which is conducive to the operation of the robot. There is no need for the user to accurately park the robot at a suitable position in the air before starting the operation, which reduces the difficulty of operating the robot and improves the operation efficiency.

[0045] It should be noted that when the limiting component 5 is not subjected to external force, for example, when the cable 6 passes over the edge of the limiting component 5 and enters the clamping channel, the rotating pressure block 3 can be reset under the action of gravity to shrink the clamping channel. The rotating pressure block 3 cooperates with the fixed pressure block 4 to clamp the cable 6. The rotating pressure block 3 can also be reset under the action of other auxiliary parts to shrink the clamping channel.

[0046] In an optional embodiment, in order to ensure that the rotating pressing block 3 and the fixed pressing block 4 can effectively clamp the cable 6, the rotating pressing block 3 is reset under the action of other auxiliary parts to reduce the clamping channel.

[0047] Specifically, Figure 2 As shown, the rotating pressing block 3 includes a pressing block body 31 and a first elastic member 32 . The pressing block body 31 is rotatably connected to the bracket assembly 2 and forms a clamping channel with the fixed pressing block 4 . The first elastic member 32 is connected between the pressing block body 31 and the bracket assembly 2 .

[0048] When using, Figure 2 As shown, the limit assembly 5 opens the entrance of the clamping channel under the pressure of the cable 6 and overcomes the elastic force of the first elastic member 32 to drive the pressure block body 31 to rotate counterclockwise relative to the bracket assembly 2 to expand the entrance, so as to facilitate the cable 6 to enter the clamping channel; after the cable 6 completely enters the clamping channel, the pressure on the pressure block body 31 is cancelled, and the pressure block body 31 rotates clockwise to reset under the elastic force of the first elastic member 32, and the pressure block body 31 presses the cable 6 against the fixed pressure block 4 to prevent the cable 6 from moving downward.

[0049] The rotating pressing block 3 has a simple structure. After the robot releases the cable 6 , it can stably and effectively press the cable 6 onto the fixed pressing block 4 .

[0050] The first elastic member 32 may be, but is not limited to, a torsion spring.

[0051] In an optional embodiment, if Figure 2 As shown, in order to further increase the friction between the rotating pressure block 3 and the cable 6, and thereby ensure that the cable 6 can be stably pressed on the fixed pressure block 4, the rotating pressure block 3 has an arc surface facing the fixed pressure block 4, and the arc surface is covered with a rubber pad 311, and a clamping channel is formed between the rubber pad 311 and the fixed pressure block 4.

[0052] The arrangement of the arc surface facilitates the adjustment of the width of the clamping channel when the rotating pressing block 3 rotates relative to the bracket assembly 2, that is, Figure 2 As shown, the pressing block 3 is rotated to Figure 2 When the position shown is rotated counterclockwise by a certain angle, the width of the clamping channel increases, and the corresponding entrance of the clamping channel also increases, which facilitates the cable 6 to enter the clamping channel; when the pressure block 3 is rotated counterclockwise to reset, the width of the clamping channel decreases, and the corresponding entrance of the clamping channel also decreases, thereby achieving clamping of the cable 6.

[0053] The provision of the rubber pad 311 can increase the friction between the rotating pressing block 3 and the cable 6 , thereby ensuring that the cable 6 is not easy to move downward after the robot releases the cable 6 .

[0054] Specifically, Figure 2 As shown, when the rotating pressing block 3 includes a pressing block body 31 and a first elastic member 32 , the pressing block body 31 includes a rotating frame 312 and a rubber pad 311 . The rotating frame 312 has an arc surface, and the rubber pad 311 covers the arc surface of the rotating frame 312 .

[0055] There are many ways to connect the rubber pad 311 and the rotating frame 312, for example, the rubber pad 311 and the rotating frame 312 are bonded by colloid, or the rubber pad 311 and the rotating frame 312 are clamped, or the rubber pad 311 and the rotating frame 312 are connected by screws, etc.

[0056] In a preferred embodiment, a plurality of mounting holes are provided on the rotating frame 312, such as Figure 3 As shown, a clamping block 3113 is protruded from the surface of the rubber pad 311 away from the fixed pressing block 4 , and the clamping block 3113 can penetrate the installation through hole and be clamped on the rotating frame 312 to facilitate the connection between the rubber pad 311 and the rotating frame 312 .

[0057] The end of the clamping block 3113 is in an inverted trapezoidal shape, which can ensure that the clamping block 3113 is stably clamped on the rotating frame 312 .

[0058] In addition, the rotating frame 312 can be approximately semicircular, with multiple mounting holes opened on the semicircular arc surface. One end of the rotating frame 312 is rotatably connected to the bracket assembly 2 through a rotating shaft, and a pressure cap 9 is provided on the rotating shaft to prevent the rotating frame 312 from falling.

[0059] In an optional embodiment, if Figure 3 As shown, the surface of the rubber pad 311 away from the curved surface has a first protrusion 3111 and a second protrusion 3112 .

[0060] The first protrusion 3111 and the second protrusion 3112 can further increase the friction between the rubber pad 311 and the cable 6 , thereby ensuring the stability of the cable 6 when being clamped.

[0061] The first protrusion 3111 and the second protrusion 3112 may have the same structure or different structures. In an optional embodiment, for example Figure 3 As shown, the surface of the first protrusion 3111 facing the fixed pressing block 4 is a plane, and the surface of the second protrusion 3112 facing the fixed pressing block 4 is a curved surface, which can increase the friction between the rubber pad 311 and the cable 6 in all directions.

[0062] Specifically, Figure 3 As shown, the first protrusion 3111 can be cylindrical, and the second protrusion 3112 can be a strip structure with a semicircular cross-section. The first protrusion 3111 and the second protrusion 3112 are both configured in plurality and are alternately distributed along the extension direction of the rotation axis of the rotating pressing block 3.

[0063] Optionally, the first protrusion 3111 may be a cylindrical protrusion with a diameter of 1 mm and a height of 0.5 mm, and the second protrusion 3112 may be an arc-shaped bar with a semicircular cross-section and a diameter of 1.5 mm.

[0064] In an optional embodiment, if Figure 4 As described above, the fixed pressing block 4 includes a pressing strip 41 extending obliquely, and the pressing strip 41 gradually inclines upward in a direction gradually approaching the rotating pressing block 3 .

[0065] When the cable 6 completely enters the clamping channel, the robot drags the cable 6 upwards. Figure 2 As shown, the dragging force can overcome the elastic force of the first elastic member so that the pressure block body 31 swings counterclockwise at a certain angle, and at the same time the pressure strip 41 will not hinder the upward movement of the cable 6; after the robot and the cable 6 are separated, the cable 6 has a tendency to move downward under the action of gravity, and under the action of friction and the elastic force of the first elastic member 32, the pressure block body 31 swings clockwise, the cable 6 squeezes the pressure strip 41, the pressure strip 41 is deformed, and the pressure strip 41 further increases the pressure applied to the cable 6, thereby ensuring that the cable 6 is stably clamped between the pressure block body 31 and the pressure strip 41.

[0066] The fixed pressure block 4 has a simple structure and can effectively cooperate with the pressure block body 31 to clamp the cable.

[0067] In an optional embodiment, if Figure 4 As shown, the pressure strips 41 are configured in multiples, and the multiple pressure strips 41 are evenly spaced and distributed in parallel along the vertical direction. The above arrangement can increase the contact area between the fixed pressure block 4 and the cable 6, and each pressure strip 41 can clamp the cable 6, so that the clamping effect of the cable 6 is better.

[0068] Specifically, the thickness of a single bead 41 may be 2.5 mm, and the interval between adjacent bead 41 is 2.5 mm.

[0069] Optionally, the material and hardness of the first protrusion 3111, the second protrusion 3112 and the pressure strip 41 are all polyurethane A80.

[0070] In an optional embodiment, if Figure 1 As shown, the limiting assembly 5 includes a sleeve seat 51, a slider 52 and a second elastic member 53. The sleeve seat 51 can be fixedly connected to the rotating pressure block 3 by connecting members such as screws; the slider 52 is slidably matched with the sleeve seat 51; and the second elastic member 53 is clamped between the sleeve seat 51 and the slider 52.

[0071] When installing cable 6, Figure 1 and Figure 2 As shown, the cable 6, driven by the robot, overcomes the elastic force of the second elastic member 53 to squeeze the slider 52, and the slider 52 moves to the left relative to the sleeve seat 51, forcing the limit assembly 5 to open the entrance of the clamping channel. At the same time, the slider 52 transmits the squeezing force to the pressure block body 31 through the sleeve seat 51, so that the pressure block body 31 rotates counterclockwise relative to the bracket assembly 2 to expand the entrance of the clamping channel. When the cable 6 passes over the edge of the slider 52 and enters the interior of the clamping channel, the second elastic member 53 drives the slider 52 to move right and reset, and the slider 52 blocks the entrance of the clamping channel. At the same time, the pressure block body 31 is reset under the action of the first elastic member 32, squeezing the cable 6.

[0072] Specifically, the sliding direction of the slider 52 relative to the sleeve seat 51 is perpendicular to the rotation axis of the rotating pressure block 3 relative to the bracket assembly 2, and the two do not intersect, so that when the slider 52 transmits the extrusion force to the pressure block body 31 through the sleeve seat 51, the force will not directly act on the rotation axis of the rotating pressure block 3. The force generates a certain torque relative to the axis of the rotating pressure block 3, which facilitates the rotation of the rotating pressure block 3.

[0073] In a preferred embodiment, when the cable 6 squeezes the slider 52, the slider 52 slides obliquely upward relative to the sliding sleeve seat 51, and the rotation axis of the rotating pressure block 3 relative to the bracket assembly 2 is located on the lower side of the sliding path of the slider 52 relative to the sliding sleeve seat 51, so that when the slider 52 transmits the squeezing force to the pressure block body 31 through the sliding sleeve seat 51, the pressure block body 31 can rotate counterclockwise.

[0074] In an optional embodiment, the sliding sleeve seat 51 has a through hole, and the slider 52 may include a connecting column, which passes through the through hole and is slidably matched with the sliding sleeve seat 51. Figure 5 As shown, one end of the connecting column is connected to a blocking portion 521 for bearing the extrusion force given by the cable 6. When the slider 52 is not subjected to external force, the blocking portion 521 can also block the entrance of the clamping channel. The second elastic member 53 is sleeved on the outside of the connecting column and clamped between the blocking portion 521 and the sliding sleeve seat 51. The other end of the connecting column is connected to an adjusting member 522 for adjusting the distance between the blocking portion 521 and the sliding sleeve.

[0075] In the above embodiment, the sleeve seat 51 and the second elastic member 53 are limited between the adjusting member 522 and the blocking portion 521, and the adjusting member 522 can be movably connected to the connecting column, for example, the adjusting member 522 is threadedly connected to the connecting column. When in use, the adjusting member 522 is rotated, and since the second elastic member 53 is retractable, the distance between the adjusting member 522 and the blocking portion 521 can be adaptively increased or decreased, thereby changing the distance between the blocking portion 521 and the sleeve, so that the user can adjust the blocking portion 521 to block the entrance of the clamping channel to adapt to cables 6 of different diameters.

[0076] The second elastic member 53 may be, but is not limited to, a coil spring.

[0077] In addition, the blocking portion 521 has a guide slope on the side away from the clamping channel. In the direction gradually away from the connecting column, the guide slope gradually tilts closer to the clamping channel. After the cable 6 contacts and squeezes the guide slope, it can force the slider 52 to slide relative to the sliding sleeve seat 51.

[0078] The included angle between the guiding inclined surface and the vertical plane may be 40°.

[0079] In an optional embodiment, if Figure 2 and 5 As shown, the bracket assembly 2 includes a guide bracket 21 and a support frame 22 connected to the guide bracket 21, at least one of the guide bracket 21 and the support frame 22 is connected to the insulator body 1, the fixed pressure block 4 is fixed to the support frame 22, the rotating pressure block 3 is rotatably connected to the support frame 22, and the guide bracket 21 has a guide channel for guiding the cable 6 to the limit assembly 5.

[0080] by Figure 2 For example, the guide bracket 21 is connected to the insulator body 1, and the support frame 22 is connected to the top of the guide bracket 21. The guide bracket 21 has a guide channel, and the guide channel can guide the cable 6 to the limit component 5 when installing the cable 6, which makes it easier for the user to use a robot to drive the cable 6 to align with the limit component 5, thereby reducing the difficulty of operation for the user.

[0081] In an optional embodiment, if Figure 2 and 5 As shown, the guide bracket 21 may be U-shaped, with a closed end connected to the insulator body 1 and an open end for the cable 6 to enter.

[0082] In an optional embodiment, if Figure 5As shown, a baffle 7 is connected to one end of the guide bracket 21 away from the insulator body 1, one end of the baffle 7 is rotatably connected to the guide bracket 21 through the shaft 011, and the other end is against the inner wall of the guide channel formed by the guide bracket 21, and a third elastic member 8 is provided between the baffle 7 and the guide bracket 21, so that the baffle 7 opens the guide channel under the pressure of the cable 6 and resets the closed guide channel when not subject to external force.

[0083] When in use, the cable 6 moves toward the baffle 7 driven by the robot, and the cable 6 contacts and overcomes the elastic force of the third elastic member 8 to squeeze the baffle 7, causing it to rotate open, and the cable 6 enters the guide channel. At this time, the baffle 7 is reset under the action of the third elastic member 8, closing the guide channel and preventing the cable from escaping from the guide bracket 21.

[0084] The third elastic member 8 may be, but is not limited to, a torsion spring.

[0085] In an optional embodiment, if Figure 5 As shown, when the blocking piece 7 is not subjected to external force, a guide opening 10 is formed between the blocking piece 7 and the guide bracket 21 , and the opening of the guide opening 10 gradually increases in a direction away from the limiting assembly 5 .

[0086] The above arrangement facilitates the cable 6 to align with the baffle 7, thereby pushing the baffle 7 into the guide channel.

[0087] Specifically, the guide opening 10 is at an angle of 145°.

[0088] An embodiment of the second aspect of the present invention provides a cable installation method. The cable installation method provided by the embodiment of the second aspect of the present invention adopts the above-mentioned cable auxiliary installation device, including:

[0089] The robot drives the cable 6 to squeeze the limiting assembly 5, and the limiting assembly 5 opens the entrance of the clamping channel and drives the rotating pressing block 3 to rotate relative to the bracket assembly 2 to expand the entrance of the clamping channel;

[0090] After the cable 6 passes over the edge of the limiting assembly 5 and enters the interior of the clamping channel, the rotating pressing block 3 and the fixed pressing block 4 clamp the cable 6 together, and the limiting assembly 5 is reset to block the entrance of the clamping channel;

[0091] The robot drags the cable 6 upward, and the clamping channel allows the cable to move upward. After the cable is in place, the robot releases the cable 6, and the clamping channel prevents the cable 6 from moving downward.

[0092] The following is a detailed description of the cable installation method:

[0093] 1. The cable 6 moves toward the baffle 7 under the drive of the robot. Under the guidance of the guide opening 10, the cable 6 contacts and squeezes the baffle 7, causing it to rotate and open. The cable 6 enters the guide channel. At this time, the baffle 7 is reset under the action of the third elastic member 8, closing the guide channel to prevent the cable from escaping from the guide bracket 21.

[0094] 2. The cable 6 continues to move toward the blocking portion 521 driven by the robot, and contacts and squeezes the guiding inclined surface of the blocking portion 521, forcing the slider 52 to slide relative to the sliding sleeve seat 51. At the same time, the pressing block body 31 is driven to rotate upward and open;

[0095] 3. The cable 6 continues to move toward the clamping channel. When the cable 6 exceeds the edge of the blocking portion 521 and enters the inside of the clamping channel, the slider 52 is reset under the action of the second elastic member 53 and blocks the cable 6 by the plane on the rear side of the slider 52. The pressing block body 31 and the fixed pressing block 4 clamp the cable 6.

[0096] 4. The robot drags the cable 6 upwards, and the cable 6 drives the pressing block body 31 to rotate upwards. At the same time, the cable 6 presses the pressing bar 41 upwards so that the cable 6 can move upwards;

[0097] 5. After the cable 6 reaches the position, the robot and the cable 6 are separated. Under the action of gravity, the cable 6 tends to move downward. The pressing block body 31 rotates downward under the action of the first elastic member 32. At the same time, the cable 6 brings up the pressure strip 41 and presses the pressure strip 41 obliquely downward, and the pressure strip 41 prevents the cable 6 from moving downward.
