Description

Technical Field

[0001] This utility model relates to the field of connection structure technology, specifically to a high-altitude escape device for a live-line working robotic arm. Background Technology

[0002] Power equipment maintenance is a crucial link in ensuring the safe, stable, and economical operation of the power system, directly affecting the operating status of equipment and the quality of power supply. During live-line work, operators often need to perform complex manual operations such as wiring and disconnecting wires in extremely dangerous environments such as high altitudes, high voltages, and strong electromagnetic fields. This is not only labor-intensive but also carries extremely high safety risks. To improve operational safety, live-line work vehicles are typically used for remote control.

[0003] Existing live-line maintenance vehicles mainly consist of a carrier vehicle, a robotic arm, and end effectors (such as wire strippers, wire clamp installation tools, insulation cover installation devices, and wire cutters). The end effectors are typically fixed to the end of the robotic arm using rigid connections such as bolts. However, when the robotic arm is operating at height, if the control system malfunctions or experiences a sudden failure, it is difficult to quickly separate the end effectors from the robotic arm. This can lead to the robotic arm being unable to detach from the live conductor in a timely manner, significantly increasing the risk of the equipment remaining in the energized area and potentially causing electric shock. Utility Model Content

[0004] The purpose of this utility model is to provide a high-altitude escape device for a live-line working robotic arm, which solves the problem that when the control system of an existing live-line working maintenance vehicle malfunctions or crashes at high altitudes, it is difficult to quickly separate the operating tools from the robotic arm, thus making it difficult for the robotic arm to detach from the live main line in time, which greatly increases the risk of electric shock accidents caused by the equipment being stuck in the live area.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for escaping a live-line working robot arm from a height is provided, comprising a first arc-shaped plate, a second arc-shaped plate, and a locking member. The second arc-shaped plate is disposed opposite to the first arc-shaped plate, and one end of the second arc-shaped plate is hinged to one end of the first arc-shaped connecting plate. The inner wall of the second arc-shaped plate is provided with a connecting groove, which extends from one end of the second arc-shaped plate to the other end of the first arc-shaped plate, and the connecting groove is used to connect the operating tool and the robot arm. The locking member is disposed on the first arc-shaped plate, and the locking member is used to connect the other end of the first arc-shaped plate to the other end of the second arc-shaped plate.

[0007] A further technical solution is that the first or second arc-shaped plate is provided with mounting holes; wherein, the mounting holes are used to reserve mounting positions for mounting the first or second arc-shaped plate on the robotic arm.

[0008] A further technical solution is as follows: the other end of the second arc-shaped plate is provided with a receiving groove; the locking member includes a connecting rod and a locking knob; the connecting rod is connected to the other end of the first arc-shaped plate, and the connecting rod passes through the receiving groove; the locking knob is located at the end of the connecting rod away from the first arc-shaped plate, and the locking knob can move along the connecting rod towards or away from the second arc-shaped plate; wherein, the locking knob is used to abut against the outer wall of the second arc-shaped plate.

[0009] A further technical solution is that the connecting rod is hinged to the first arc-shaped plate.

[0010] A further technical solution is: the longitudinal cross-sectional area of ​​the locking knob gradually increases along the connecting rod in the direction away from the first arc plate; a limiting groove is formed on the outer wall of the second arc plate, and the limiting groove is adapted to the end of the locking knob near the first arc plate.

[0011] A further technical solution is that the locking knob is screwed onto the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When a control system crashes or malfunctions, requiring the separation of the operating tool and robotic arm, the locking mechanism is released, and the free ends of the first and second arc-shaped plates are moved away from each other. This allows the operating tool and robotic arm to be pulled out of the connecting slot. Then, the robotic arm is moved away from the operating tool, thus achieving rapid separation. The aim is to quickly separate the operating tool and robotic arm, enabling the robotic arm to rapidly escape from energized areas, thereby significantly reducing the risk of electric shock, short circuits, and other serious accidents caused by live wires remaining on the equipment.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: This example provides a high-altitude escape device for a live-line working robot, such as... Figures 1-5 As shown, the device includes a first arc-shaped plate 1, a second arc-shaped plate 2, and a locking member 4. The second arc-shaped plate 2 is disposed opposite to the first arc-shaped plate 1, and one end of the second arc-shaped plate 2 is hinged to one end of the first arc-shaped connecting plate. The inner wall of the second arc-shaped plate 2 is provided with a connecting groove 3, which extends from the other end of the second arc-shaped plate 2 to the other end of the first arc-shaped plate 1, and the connecting groove 3 is used to connect the operating tool 9 and the robotic arm 8. The locking member 4 is disposed on the first arc-shaped plate 1, and the locking member 4 is used to connect the other end of the first arc-shaped plate 1 and the other end of the second arc-shaped plate 2.

[0025] For example, in implementation, the first arc-shaped plate 1 and the second arc-shaped plate 2 are arranged with their slots facing each other, and one end of the second arc-shaped plate 2 is hinged to one end of the first arc-shaped plate 1 through a hinge shaft, hinge, or other structure, so that the first arc-shaped plate 1 and the second arc-shaped plate 2 together form an openable and closable annular clamping structure. A connecting groove 3 is provided on the inner wall of the second arc-shaped plate 2 (i.e., the side wall of the second arc-shaped plate 2 near the first arc-shaped plate 1), and the connecting groove 3 extends from the other end of the second arc-shaped plate 2 (i.e., the free end of the second arc-shaped plate 2) to the other end of the first arc-shaped plate 1. That is, after the connecting groove 3 extends from the other end of the second arc-shaped plate 2 to one end of the second arc-shaped plate 2, it extends again through one end of the first arc-shaped plate 1 to the other end of the first arc-shaped plate 1, so as to form an annular connecting groove 3 on the inner wall of the first arc-shaped plate 1 and the second arc-shaped plate 2. That is, the connecting groove 3 includes a first groove element and a second groove element, which are arranged opposite to each other on the inner wall of the first arc-shaped plate 1 and the second arc-shaped plate 2. The connecting groove 3 is used to accommodate the ends of the operating tool 9 and the robotic arm 8 that are close to each other, thereby achieving axial positioning between the operating tool 9 and the robotic arm 8. Specifically, a limiting protrusion 10 is provided on the end face of the operating tool 9 near the robotic arm 8, and a limiting groove 11 is provided on the end face of the robotic arm 8 near the operating tool 9. The limiting protrusion 10 fits into the limiting groove 11, thereby achieving radial positioning between the operating tool 9 and the robotic arm 8. A first folded edge 12 is provided on the outer wall of the end of the operating tool 9 near the robotic arm 8, and a second folded edge 13 is provided on the outer wall of the end of the robotic arm 8 near the operating tool 9. In use, when the operating tool 9 and the robotic arm 8 are in contact, the limiting protrusion 10 fits into the limiting groove 11, and the first folded edge 12 and the second folded edge 13 can fit into the connecting groove 3, thereby achieving longitudinal and axial positioning between the operating tool 9 and the robotic arm 8.

[0026] The locking component 4 can be a bolt and nut structure, quick clamp, or other mechanism. The locking component 4 is connected to the other end (free end) of the first arc plate 1 by welding, screwing, or other means. The locking component 4 is used to lock the free ends of the first arc plate 1 and the second arc plate 2 when the first arc plate 1 and the second arc plate 2 are in a closed state, so as to reduce the risk of the first arc plate 1 and the second arc plate 2 accidentally opening.

[0027] During use, when connecting the operating tool 9 and the robotic arm 8, first open the locking member 4 and drive the free ends of the first arc plate 1 and the second arc plate 2 away from each other. Next, attach the operating tool 9 to the robotic arm 8 and fit the limiting protrusion 10 on the operating tool 9 into the limiting groove 11 on the robotic arm 8. Then, fit the first folded edge 12 and the second folded edge 13 of the operating tool 9 and the robotic arm 8, which are close to each other, into the connecting grooves 3 on the first arc plate 1 and the second arc plate 2. Finally, drive the free ends of the first arc plate 1 and the second arc plate 2 closer together, and then operate the locking member 4 to lock the free ends of the first arc plate 1 and the second arc plate 2.

[0028] When the robotic arm 8 is performing high-altitude operations, the operating tool 9 is often hooked onto the live main line.

[0029] When a control system crashes or malfunctions, requiring the separation of the operating tool 9 and the robotic arm 8, the locking element 4 is released, and the free ends of the first arc plate 1 and the second arc plate 2 are driven away from each other, allowing the operating tool 9 and the robotic arm 8 to be pulled out of the connecting groove 3. Then, the robotic arm 8 is driven away from the operating tool 9, thus completing the rapid separation between them. This aims to achieve rapid separation of the operating tool 9 and the robotic arm 8, enabling the robotic arm 8 to quickly leave the energized area, thereby significantly reducing the risk of electric shock, short circuits, and other major accidents caused by live wires remaining on the equipment. Simultaneously, it aims to enable rapid replacement of different functional operating tools 9 (such as wire strippers, wire clamp installation tools, insulation cover installation devices, wire cutters, etc.), thereby shortening preparation time and improving the overall efficiency of live-line work.

[0030] To reduce the risk of loss of the high-altitude escape device for live-line working robotic arms. Example 2: Based on Example 1 above, in this example, as... Figure 1 As shown, the first arc plate 1 or the second arc plate 2 is provided with mounting holes 5; wherein, the mounting holes 5 are used to reserve mounting positions for mounting the first arc plate 1 or the second arc plate 2 on the robotic arm 8.

[0031] For example, during implementation, the first arc-shaped plate 1 (second arc-shaped plate 2) is provided with mounting holes 5. The mounting holes 5 are used to reserve a mounting position for mounting the first arc-shaped plate 1 (second arc-shaped plate 2) on the robotic arm 8.

[0032] During use, the first arc-shaped plate 1 (second arc-shaped plate 2) is connected to the end of the robotic arm 8 closest to the operating work area via fasteners such as bolts, rivets, or pins through the mounting hole 5. This is intended to effectively ensure the connection stability between the high-altitude escape device and the robotic arm 8 in situations such as vibration, impact, misoperation during high-altitude operations, unlocking of the locking component 4, opening of the first arc-shaped plate 1, or separation of the operating tool 9, thereby reducing the risk of falling objects and lost components.

[0033] In a preferred embodiment, to reduce the risk of dryness during the opening and closing of the first arc-shaped plate 1 and the second arc-shaped plate 2 at the connection point between the mounting hole 5 and the robotic arm 8, the mounting hole 5 is located on the axis at the hinge position of the first arc-shaped plate 1 and the second arc-shaped plate 2.

[0034] Example 3: Based on Example 1 above, in this example, as follows... Figure 1 As shown, the other end of the second arc-shaped plate 2 is provided with a receiving groove 6; the locking member 4 includes a connecting rod 41 and a locking knob 42; the connecting rod 41 is connected to the other end of the first arc-shaped plate 1, and the connecting rod 41 passes through the receiving groove 6; the locking knob 42 is located at the end of the connecting rod 41 away from the first arc-shaped plate 1, and the locking knob 42 can move along the connecting rod 41 towards or away from the second arc-shaped plate 2; wherein, the locking knob 42 is used to abut against the outer wall of the second arc-shaped plate 2.

[0035] For example, during implementation, the other end (free end) of the second arc-shaped plate 2 is provided with a receiving groove 6.

[0036] The aforementioned locking component 4 includes a connecting rod 41 and a locking knob 42. One end of the connecting rod 41 is connected to the other end (free end) of the first arc-shaped plate 1 by means of welding, screwing, riveting, hinge, etc. The locking knob 42 passes through the end of the connecting rod 41 away from the first arc-shaped plate 1, and the locking knob 42 can move along the connecting rod 41.

[0037] During use, when it is necessary to lock the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2, first bring the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2 closer together. Next, insert the connecting rod 41 into the receiving groove 6. Then, drive the locking knob 42 towards the second arc-shaped plate 2 (along the connecting rod 41 towards the first arc-shaped plate 1) until the locking knob 42 abuts against the outer wall of the other end of the second arc-shaped plate 2 (i.e., the side away from the first arc-shaped plate 1). To unlock the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2, simply reverse the operation. Locking and unlocking can be completed by moving the locking knob 42 without additional tools. This design aims to make operation intuitive and effortless, especially suitable for operation while wearing insulated gloves in high-altitude work environments.

[0038] In one optional embodiment, the locking component 4 further includes a spring, which is sleeved on the connecting rod 41. One end of the spring is connected to the end of the connecting rod 41 away from the first arc-shaped plate 1 by welding, screwing, or other means, and the other end of the spring is connected to the locking knob 42 by welding, screwing, or other means. During use, external force is first used to drive the locking knob 42 along the connecting rod 41 in a direction away from the first arc-shaped plate 1 to compress the spring. When the connecting rod 41 is inserted into the receiving groove 6, the external force is released. At this time, the spring force drives the locking knob 42 along the connecting rod 41 in a direction closer to the first arc-shaped plate 1 until the locking knob 42 abuts against the outer wall of the other end of the second arc-shaped plate 2 (i.e., the side away from the first arc-shaped plate 1).

[0039] To facilitate the insertion of the connecting rod 41 into the receiving groove 6. Example 4: Based on Example 3 above, as... Figure 1 As shown, in this embodiment, the connecting rod 41 is hinged to the first arc-shaped plate 1.

[0040] For example, during implementation, the connecting rod 41 is hinged to the first arc-shaped plate 1 via a hinge shaft or pin.

[0041] During use, when it is necessary to lock the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2, firstly, bring the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2 closer together. Next, rotate the connecting rod 41 to push it into the receiving groove 6. Then, drive the locking knob 42 towards the second arc-shaped plate 2 (along the connecting rod 41 towards the first arc-shaped plate 1) until the locking knob 42 abuts against the outer wall of the other end of the second arc-shaped plate 2 (i.e., the side away from the first arc-shaped plate 1). To unlock the free ends of the first arc-shaped plate 1 and the second arc-shaped plate 2, simply reverse the operation. This is intended to facilitate the operator's rotation of the connecting rod 41 and pushing it into or out of the receiving groove 6.

[0042] To reduce the risk of slippage within the self-accommodating groove 6 of the connecting rod 41. Example 5: Based on Example 3 or Example 4 above, in this example, as... Figure 1 , Figure 2 Combination Figure 3 As shown, the longitudinal cross-sectional area of ​​the locking knob 42 gradually increases along the connecting rod 41 in the direction away from the first arc plate 1; a limiting groove 7 is provided on the outer wall of the second arc plate 2, and the limiting groove 7 is adapted to the end of the locking knob 42 near the first arc plate 1.

[0043] For example, during implementation, the longitudinal cross-sectional area of ​​the locking knob 42 gradually increases along the connecting rod 41 in the direction away from the first arc-shaped plate 1. That is, the locking knob 42 is conical or mushroom-shaped, and the diameter of the end of the locking knob 42 near the first arc-shaped plate 1 is smaller, while the diameter of the end of the first arc-shaped plate 1 is larger.

[0044] A limiting groove 7 is formed on the outer wall of the second arc-shaped plate 2 (i.e., the side of the second arc-shaped plate 2 away from the first arc-shaped plate 1). The shape of the limiting groove 7 is adapted to the locking knob 42. That is, the limiting groove 7 is an annular groove or a U-shaped groove, and its size and depth match the end of the locking knob 42 near the first arc-shaped plate 1 (i.e., the smaller diameter end). When the locking knob 42 moves toward the second arc-shaped plate 2 and presses against the outer wall of the second arc-shaped plate 2, the end of the locking knob 42 near the first arc-shaped plate 1 (i.e., the smaller diameter end) is embedded in the limiting groove 7, forming a mechanical engagement. This is intended to reduce the risk of the connecting rod 41 slipping out of the self-accommodating groove 6 under vibration, impact, or accidental pulling, thereby improving the connection stability.

[0045] Example 6: Based on Example 5 above, in this example, as... Figure 2 As shown, the locking knob 42 is screwed onto the connecting rod 41.

[0046] For example, in implementation, the locking knob 42 has a threaded hole, and the connecting rod 41 has an external thread. The locking knob 42 is screwed onto the external thread of the connecting rod 41 through the threaded hole.

[0047] During use, rotating the locking knob 42 will cause it to move along the connecting rod 41 towards or away from the first arc-shaped plate 1. This is intended to facilitate the operator in moving the locking knob 42 along the connecting rod 41, thereby improving the efficiency of quickly separating the operating tool 9 from the robotic arm 8.

More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims.
