Description

Technical Field

[0001] The utility model relates to the technical field of rescue machines, in particular to a traction mechanism for an overhead line rescue machine. Background Art

[0002] A cable wrapping robot refers to a walking robot used to wrap an insulating layer on an exposed overhead line. Existing cable wrapping robots, such as Chinese patent CN 116488055 A, disclose a cable wrapping robot and a wrapping method thereof. The cable wrapping robot has a certain probability of failure during operation. Generally, if a cable wrapping robot is suspended on an overhead line due to a failure, the cable wrapping robot can only be towed back manually. Due to the high height of the overhead line, this operation has problems such as low work efficiency and high risk factor when towed back manually, especially due to the restrictions of weather conditions and other factors.

[0003] At the same time, during rescue operations, due to the high overhead lines, the line of sight may be limited under different environmental conditions, and the position of the cable wrapping robot cannot be observed by human eyes. It is easy to touch obstacles, and the position and distance of the cable wrapping robot cannot be quickly and accurately located, requiring a lot of manual intervention, which reduces work efficiency.

[0026] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0027] like Figures 1 to 4 The traction mechanism for an overhead line rescue machine shown in the figure comprises a walking mechanism 1, on which a hook assembly 6 is mounted, the hook assembly 6 is opened toward the direction of the cable wrapping robot, and a probe 51 and a rangefinder 52 are mounted on the walking mechanism 1;

[0028] Main boards 53 are installed on both the front and rear sides of the walking mechanism 1. The two main boards 53 are connected by a mounting plate, and the hook assembly 6 is installed on the mounting plate.

[0029] The directions of the probe 51 and the rangefinder 52 are consistent with the direction of the hook assembly 6 , and the rangefinder 52 is installed on any main board 53 or on the board surface of any opening and closing arm 36 in the walking mechanism 1 .

[0030] like Figure 2 As shown, the hook assembly 6 includes a hook mounting plate 26, on which a hook mounting seat 27 is mounted, in which a hook 28 with a gear is clamped, and on the hook mounting seat 27 a hook motor 25 is mounted, on the output rod of the hook motor 25 a gear 29 is mounted, and the hook 28 and the gear 29 are meshed with each other.

[0031] The hook claw 28 is divided into an upper hook claw body and a lower hook claw body. The upper hook claw body is arranged opposite to the lower hook claw body. Each hook claw body is divided into a hook head and a hook handle joint. The outer peripheral wall of the hook handle joint is provided with a tooth structure that meshes with the gear 29.

[0032] You can choose to use either the upper hook split or the lower hook split according to the actual working conditions.

[0033] The probe 51 can monitor the status of the hook assembly 6 in real time to ensure that the rescue machine can correctly approach and hook the auxiliary rope or shell, which helps to prevent potential problems, achieve a higher degree of automated operation, reduce manual intervention, and improve work efficiency. Under different environmental conditions, such as insufficient light or obstructed vision, the probe can help the rescue machine work normally. With the assistance of the probe, the rescue machine can more accurately perform the operations of hooking, positioning and fixing the auxiliary rope or shell, improving the quality of work. The probe can support remote operation, and the operator can control the rescue machine from a safe location to further improve safety.

[0034] The rangefinder 52 can help the operator accurately measure the distance between the cable wrapping robot and the rescue machine. In aerial operations, it can avoid collisions and provide real-time distance information to help the operator control the rescue machine to maintain a safe distance. Through the rangefinder 52, the rescue machine can quickly determine the position and distance of the cable wrapping robot, reduce the time for searching and positioning, and improve work efficiency. The data from the rangefinder can be used to automatically adjust the position and movement of the rescue machine for more precise control. It can provide distance information that is more reliable than the naked eye. It can reduce the risks caused by visual errors or misjudgments. Accurate distance measurement helps to ensure the quality and accuracy of the auxiliary rope or shell hook, and avoids operation failures due to distance misjudgment.

[0035] like Figures 3-4 As shown, the walking mechanism 1 includes a walking body, on which an opening and closing arm 36 with arm teeth, an opening and closing motor 37 and a rotating shaft 38 are installed, and the walking body is provided with two sets of rotating shafts 38 arranged in parallel. The two sets of opening and closing arms 36 are respectively connected to the corresponding rotating shafts 38;

[0036] The output end of the opening and closing motor 37 is connected to the second transmission assembly 39, and the second transmission assembly 39 is connected to a rotating shaft 38, driving the opening and closing motor 37, and driving a rotating shaft 38 to rotate, so that the opening and closing arm 36 on the rotating shaft 38 is meshed with the other opening and closing arm 36, and the two opening and closing arms 36 are in a closed or open state;

[0037] A lower tug assembly 41 is installed between the two opening and closing arms 36, a semi-travel hanging wheel 44 is installed on the inner side of the upper end of each opening and closing arm 36, a second drive motor 43 is installed on both opening and closing arms 36, the second drive motor 43 is connected to the semi-travel hanging wheel 44 through a third transmission assembly, and a stepper motor 42 is also installed on the walking body, and the stepper motor 42 is connected to the lower tug assembly 41 through the third transmission assembly;

[0038] A locking assembly 40 is provided at the top of the opening and closing arms 36 for interlocking the two opening and closing arms 36 when they are closed. When the two opening and closing arms 36 are closed, their respective semi-travel hanging wheels 44 are aligned and interlocked through the locking assembly 40 .

[0039] Working process:

[0040] Step 1: Manually send the rescue machine to the overhead line that needs rescue, and move it toward the package robot through the walking structure 1;

[0041] Step 2: After approaching, the operator observes the distance between the rescue machine and the wrapping robot and the position of the hook assembly 6 in real time from below through the cooperation of the probe 51 and the rangefinder 52, and moves the rescue machine to an appropriate position;

[0042] Step 3: Any hook in the hook assembly 6 hooks the auxiliary rope or the shell of the cable-wrapped robot, and then confirms again whether it is hooked through the probe 51;

[0043] At the same time, the two running wheels of the walking mechanism on the cable wrapping robot suspend the cable wrapping robot as a whole on the overhead line. After the rescue machine is started, the cable wrapping robot walks on the overhead line through the two running wheels.

[0044] Step 4: Finally, start the walking mechanism 1 to drag back the faulty cable wrapping robot to complete the rescue.

[0045] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description.
