Description

Technical Field

[0001] This application relates to the field of cleaning pliers technology, and in particular to cleaning pliers. Background Technology

[0002] The overhead contact line is a special power transmission line erected along the railway line to provide electricity to electric locomotives or EMU trains, and is the core part of the traction power supply system of electrified railways. However, in actual operation, the overhead contact line often faces interference from foreign objects. Various foreign objects such as tree branches, plastic film, tarpaulins, billboards, and metal plates frequently fall onto the contact line, causing faults such as contact line circuit breaks and tripping.

[0003] In related technologies, workers usually only modify the insulating rod to make a simple cleaning device. However, when cleaning foreign objects, the cleaning device is difficult to grasp and remove them accurately and efficiently, which results in a lot of time being spent on cleaning, reducing the work efficiency of workers and thus reducing the efficiency of foreign object removal on the contact wire. Utility Model Content

[0004] Therefore, it is necessary to provide a cleaning pliers to address the problem of low efficiency in cleaning foreign objects from overhead contact lines.

[0005] A cleaning pliers, comprising:

[0006] The support components are made of insulating material.

[0007] A clamping assembly is mounted on a support assembly. The clamping assembly includes two clamping units that are swayable relative to the support assembly to change the distance between the two clamping units.

[0008] The linkage component is connected to two clamping units to drive the two clamping units to move closer or further apart.

[0009] In one embodiment, the cleaning forceps further includes:

[0010] The drive assembly is mounted on the support assembly. The drive assembly includes a fixed unit and a drive unit. The fixed unit is hinged to one end of the clamping unit. The drive unit is mounted on the fixed unit and is driven by the linkage assembly. The drive unit drives the two clamping units to move closer or further apart through the linkage assembly.

[0011] In one embodiment, the linkage component includes:

[0012] A linkage unit, one end of which is hinged to a clamping unit;

[0013] A connecting unit is connected to a driving unit, which drives the connecting unit to move along a first direction. The other end of the linkage unit is hinged to the connecting unit.

[0014] In one embodiment, the clamping unit includes:

[0015] Clamping components;

[0016] The first connector has one end hinged to the clamping member, the other end hinged to the fixing unit, and the first connector hinged to the linkage unit.

[0017] The second connector has one end hinged to the clamping member and the other end hinged to the fixing unit.

[0018] In one embodiment, the cleaning forceps further includes:

[0019] The control component is mounted on the support component and is communicatively connected to the drive unit.

[0020] The operation component is set up independently from the control component, and the operation component is connected to the control component to control the switching of the drive unit.

[0021] In one embodiment, the cleaning forceps further includes:

[0022] The power supply component is mounted on the support component and is electrically connected to the control component and the drive component.

[0023] In one embodiment, the clamping unit is provided with serrations.

[0028] In one embodiment, the cleaning forceps further includes:

[0029] A fixing component is located at the bottom of the support component. The fixing component includes a rolling unit to drive the support component to move.

[0030] The aforementioned cleaning pliers have a support component made of insulating material, a clamping component mounted on the support component, and a linkage component connected to two clamping units to change the distance between them. With this structure, when the cleaning pliers are cleaning foreign objects, the operator can hold the support component, and the linkage component drives the two clamping units closer together to grip the foreign object. Subsequently, the linkage component drives the two clamping units further apart to release the foreign object. This configuration allows the cleaning pliers to accurately and efficiently grasp and remove foreign objects, thereby reducing the time required for cleaning, improving operator efficiency, and ultimately increasing the efficiency of foreign object removal on the contact wire.

[0048] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0054] See Figure 1 This application provides a cleaning pliers, which includes a support assembly 10, a clamping assembly 20, and a linkage assembly 30. The support assembly 10 is made of an insulating material. The clamping assembly 20 is disposed on the support assembly 10 and includes two clamping units 21. The clamping units 21 are swayable relative to the support assembly 10 to change the distance between the two clamping units 21. The linkage assembly 30 is connected to the two clamping units 21 to drive the two clamping units 21 to move closer or further apart. (See reference...) Figure 1 The X direction is the first direction.

[0055] Using the technical solution of this application, the support component 10 is made of insulating material, the clamping component 20 is disposed on the support component 10, and the linkage component 30 is connected to two clamping units 21 respectively to change the distance between the two clamping units 21. With this structure, when the cleaning pliers are cleaning foreign objects, the worker can hold the support component 10, and the linkage component 30 drives the two clamping units 21 to move closer together to clamp the foreign object. Subsequently, the linkage component 30 drives the two clamping units 21 to move away from each other to release the foreign object. This configuration allows the cleaning pliers to accurately and efficiently grasp and remove foreign objects, thereby reducing the time required for cleaning work, improving the worker's work efficiency, and ultimately improving the efficiency of foreign object removal on the contact wire.

[0056] Furthermore, adopting the above structure reduces the labor intensity of workers and ensures the normal operation of the overhead contact system. At the same time, it reduces the possibility of foreign object residue, thereby ensuring the safety of railway transportation, preventing power outages to the overhead contact system, and guaranteeing the normal operation of trains.

[0057] In some embodiments, the insulating material is a composite material with high strength and high insulation performance, such as multilayer epoxy glass fiber, which can effectively block current.

[0058] See Figure 1 The cleaning forceps also includes a drive assembly 40, which is mounted on the support assembly 10. The drive assembly 40 includes a fixing unit 41 and a drive unit 42. The fixing unit 41 is hinged to one end of the clamping unit 21, and the drive unit 42 is mounted on the fixing unit 41. The drive unit 42 is driven by the linkage assembly 30, which drives the two clamping units 21 to move closer or further apart. This configuration provides a mounting base for the drive unit 42 and the clamping assembly 20, facilitating their assembly.

[0059] In some embodiments, the length of the support component 10 extends along a first direction, and the clamping component 20 and the drive component 40 are integrated and then fixed on the support component 10, which facilitates the assembly of the cleaning forceps.

[0060] In some embodiments, the drive component 40 is a geared motor, and the fixing unit 41 is the housing of the geared motor. The geared motor has high torque output characteristics, which can convert the high-speed rotation of the geared motor into a low-speed, high-torque motion suitable for the operation of the linkage component 30, ensuring that the insulating clamp moves smoothly and powerfully when gripping foreign objects.

[0061] See Figure 1 One end of the clamping unit 21 is hinged to the fixed unit 41. The linkage assembly 30 includes a linkage unit 31 and a connecting unit 32. One end of the linkage unit 31 is hinged to the clamping unit 21. The connecting unit 32 is connected to the drive unit 42, which drives the connecting unit 32 to move along a first direction. The other end of the linkage unit 31 is hinged to the connecting unit 32. With this configuration, when the connecting unit 32 moves along the first direction, the linkage unit 31 converts the linear motion into the oscillation of the clamping unit 21 around its hinge point, thus achieving a change in motion mode. The hinge between the linkage unit 31 and the clamping unit 21 and the connecting unit 32 makes the transmission process more flexible.

[0062] In some embodiments, the linkage component 30 includes two linkage units 31, which are configured one-to-one with two clamping units 21. The linkage unit 31 is hinged to the corresponding clamping unit 21, thus ensuring the synchronicity of the movement of the two clamping units 21.

[0063] In some embodiments, the drive unit 42 has an output shaft 421, which is rotatably disposed. The connecting unit 32 has an annular structure and is sleeved on the output shaft 421. The connecting unit 32 is threadedly connected to the output shaft 421 to convert the rotation of the output shaft 421 into linear motion of the connecting unit 32. This configuration can improve the stability of the connecting unit 32 moving along the first direction.

[0064] See Figure 1 The clamping unit 21 includes a clamping member 211, a first connecting member 212, and a second connecting member 213. One end of the first connecting member 212 is hinged to the clamping member 211, and the other end is hinged to the fixing unit 41 and the linkage unit 31. One end of the second connecting member 213 is hinged to the clamping member 211, and the other end is hinged to the fixing unit 41. This configuration effectively constrains the posture of the clamping member 211 during movement, ensuring a stable angle during opening and closing, preventing rotation or swaying, and ensuring accurate alignment and gripping of foreign objects. It also improves the strength and stability of the clamping unit 21, prevents deformation of the clamping member 211, and enhances the reliability of the clamping unit 21's operation.

[0065] In some embodiments, the length of the clamping member 211 extends along the first direction. By adopting the above structure, it is possible to avoid the clamping member 211 forming an angle relative to the first direction.

[0066] In some embodiments, through the coordinated operation of the geared motor and the linkage component 30, the maximum distance between the two clamping members 211 is 10 centimeters, and a fast and precise opening and closing action can be achieved, which can easily handle the cleaning of foreign objects of various shapes and sizes.

[0067] See Figure 2 The cleaning forceps also includes a control component 50 and an operating component 60. The control component 50 is mounted on the support component 10 and is communicatively connected to the drive unit 42. The operating component 60 is independently configured from the control component 50, but is communicatively connected to it to control the switching of the drive unit 42. This configuration, using the control component 50 and operating component 60, allows workers to operate from a safe distance, preventing them from remaining in hazardous environments for extended periods, protecting their safety, and improving operational convenience.

[0068] See Figure 2The cleaning pliers also include a power supply component 70, which is mounted on the support component 10 and electrically connected to the control component 50 and the drive component 40. This design eliminates the pliers' reliance on a fixed power supply or long cables, ensuring normal operation even without an external power source. Workers can move the pliers as needed, increasing their usability and adapting them to complex working environments such as the field, thus enhancing their environmental adaptability.

[0069] In some embodiments, the cleaning forceps also includes a transmission line 90, through which the power supply component 70 and the control component 50 are electrically connected, and through the transmission line 90, the control component 50 is electrically connected to the drive component 40.

[0070] In some embodiments, the power supply component 70 is a DC battery.

[0071] In some embodiments, the support assembly 10 has a receiving cavity, the fixing unit 41 is disposed on the top of the support assembly 10, and the drive unit 42, control assembly 50, operation assembly 60 and power supply assembly 70 are disposed in the receiving cavity, thereby effectively isolating current conduction and ensuring the health of the staff.

[0072] In some embodiments, the fixing unit 41 is made of insulating material, which further protects the safety of the staff.

[0073] See Figure 1 The clamping unit 21 is provided with serrations 2111. Specifically, the clamping member 211 is provided with serrations 2111. This design increases the coefficient of friction of the surface of the clamping member 211, increases the friction between the clamping member 211 and the foreign object, and prevents the foreign object from slipping out between the two clamping members 211 due to gravity or wind force during the clamping process, thereby enhancing the reliability and firmness of the clamping.

[0074] See Figure 1 The clamping unit 21 is provided with a weight reduction hole 2112. Specifically, the clamping member 211 is provided with a weight reduction hole 2112. This design can reduce the weight of the clamping unit 21 while ensuring the structural strength of the clamping member 211, thereby reducing the load on the operator when holding it, reducing arm fatigue during long-term operation, and improving the operator's flexibility during work.

[0075] Furthermore, the clamping unit 21 is made of insulating material. This design prevents current from flowing from the contact wire to the clamping unit 21 when clamping foreign objects, thus further ensuring the health of the workers.

[0076] Specifically, both clamping units 21 are made of insulating material.

[0077] In some embodiments, only the clamping member 211 is made of an insulating material.

[0078] In other embodiments, the clamping member 211, the first connector 212, and the second connector 213 are all made of insulating material.

[0079] In some operating conditions, fasteners such as nuts or bolts are energized. In some embodiments, workers can use cleaning pliers to disassemble or assemble these fasteners, which improves efficiency and reduces the risk of injury.

[0080] See Figure 3 The support assembly 10 includes multiple support units 11, which are detachably connected to each other. A clamping assembly 20 is mounted on one of the support units 11. This configuration allows for the connection of multiple support units 11 to extend the overall length when cleaning foreign objects at higher locations, significantly expanding the working range of the cleaning pliers. This eliminates the need for frequent climbing or relocation by workers, enabling them to clean foreign objects at different distances and ensuring worker safety when near energized facilities. During transportation or storage, the support assembly 10 can be disassembled into shorter support units 11 for easier carrying and storage of the cleaning pliers.

[0081] In some embodiments, two adjacent support units 11 are threaded together. This arrangement facilitates the connection between two adjacent support units 11 and improves the stability of the connection between them.

[0082] In some embodiments, the support component 10 is telescopically oriented along a first direction. This configuration eliminates the need for on-site assembly of the support component 10, facilitating adjustments to its length along the first direction.

[0083] See Figure 4 The cleaning pliers also include a fixing component 80, which is located at the bottom of the support component 10. The fixing component 80 includes a rolling unit 82 to move the support component 10. This design allows workers to easily move the entire cleaning pliers when transferring between different work points, reducing their workload. Furthermore, the rolling unit 82 can make slight movements when adjusting the cleaning angle and position, improving the ease and flexibility of moving the cleaning pliers and reducing the physical exertion of workers during non-working hours.

[0084] In some embodiments, the fixing component 80 further includes a base 81, the support component 10 is detachably connected to the base 81, and the rolling unit 82 is disposed on the base 81. This arrangement facilitates the installation of the rolling unit 82.

[0085] In some embodiments, the rolling unit 82 is a caster wheel. This configuration allows operators to easily adjust the angle of the cleaning pliers as needed.

[0086] In some embodiments, using the above structure, the length of the insulating clamp along the first direction is 6.2 meters, and the weight is 2.5 kilograms. This configuration ensures the length of the insulating clamp along the first direction while reducing its weight, thus improving the ease of use for workers.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
