[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.
[0030] A railway contact network electrical testing probe in this embodiment relates to the field of railway maintenance technology. A detachable claw 200 is provided on a metal hook 100 so that the claw 200 can maintain good electrical contact with the metal hook 100 so that the probe can function normally.
[0031] See also Figures 1 to 6 In this embodiment, a railway contact network electric detection probe is used to clamp with a metal hook 100, including: a clamping claw 200, an antenna 300 and a clamping assembly 400. The clamping claw 200 can be inserted into the metal hook 100 and remain connected with the metal hook 100. The antenna 300 can assist the electric detection pole to protect electrical equipment and personnel. The clamping assembly 400 can enable the clamping claw 200 to clamp the metal hook 100, so that the clamping claw 200 and the metal hook 100 maintain good electrical contact.
[0032] The claw 200 is provided with a slot 210, which is inserted into one side of the metal hook 100, so that the claw 200 is connected to the metal hook 100. The antenna 300 is connected to the claw 200, which can assist the electric test pole in protecting electrical equipment and personnel.
[0033] The clamping assembly 400 includes a mounting sleeve 410 connected to the claw 200, an abutment member 420 and an elastic member 430. The mounting sleeve 410 is connected to the slot 210 through a notch. The abutment member 420 is movably inserted in the mounting sleeve 410. The abutment member 420 can move along the axial direction of the mounting sleeve 410 and can extend into the slot 210 through the notch. The elastic member 430 is sleeved on the abutment member 420. The two ends of the elastic member 430 are respectively connected to the mounting sleeve 410 and the abutment member 420. The elastic member 430 has an elastic force to stretch the mounting sleeve 410 and the abutment member 420 to move toward each other. The elastic member 430 can drive the abutment member 420 to pass through the claw 200 and abut on the metal hook 100, ensuring that the metal hook 100 and the claw 200 maintain good electrical contact, and effectively protecting electrical equipment and personnel.
[0034] In some embodiments, see 2 to Figure 5 An adjustment unit 440 is provided between the mounting sleeve 410 and the abutment member 420. The adjustment unit 440 includes a slot 441 and a block 442. The slot 441 is arranged along the axial direction of the mounting sleeve 410. The block 442 is arranged at the side of the abutment member 420. The block 442 is integrated with the abutment member 420. There is a sliding position state and an abutment state between the block 442 and the mounting sleeve 410. In the sliding state, the block 442 slides and engages in the slot 441. The block 442 cooperates with the slot 441 to limit the axial movement of the abutment member 420 along the mounting sleeve 410, so that the abutment member 420 can cooperate with the metal hooks 100 of different thicknesses. In the abutment state, the block 442 abuts against the end of the mounting sleeve 410 away from the claw 200, and the end of the abutment member 420 is completely separated from the metal hook 100, so that the clamping of the metal hook 100 can be released.
[0035] It should be noted that the adjustment unit 440 is specifically a dividing pin structure, which can be divided and positioned. In the present application, the opening of the dividing pin is mainly used to limit the axial position of the abutment member 420, so as to control the abutment degree between the abutment member 420 and the claw 200.
[0036] During use, the abutment 420 in a sliding state can move relatively away from the claw 200, so that the block 442 disengages from the slot 441 of the mounting sleeve 410. By rotating the abutment 420, the block 442 can abut against the end of the mounting sleeve 410 away from the claw 200, and the end of the abutment 420 completely disengages from the metal hook 100, thereby releasing the clamping of the metal hook 100.
[0037] In a further embodiment, an enlarged head 421 is provided at one end of the abutment 420 away from the claw 200, and the enlarged head 421 is fixedly connected to the abutment 420. The enlarged head 421 can be convenient for human hand holding and rotation. With the help of the enlarged head 421, the abutment 420 can switch between a sliding state and an abutment state.
[0038] In some embodiments, see Figures 2 to 4 The groove body 210 is provided with an anti-slip tooth 211, which is arranged on the inner side of the groove body 210, and the anti-slip tooth 211 extends relative to the abutment 420. The anti-slip tooth 211 can be clamped in the metal hook 100 to prevent the claw 200 from escaping from the metal hook 100.
[0039] It should be noted that: grooves 110 are provided on both sides of the metal hook 100 (such as Figure 6 As shown), the groove 110 is embedded in the interior of the metal hook 100, and the anti-slip tooth 211 can be inserted into the groove 110 to abut against the metal hook 100 at multiple angles, thereby limiting the axial movement of the metal hook 100 along the abutment 420 and along a plane perpendicular to the axial direction of the abutment 420, ensuring that the claw 200 can abut tightly against the metal hook 100, so that the claw 200 and the metal hook 100 maintain a good electrical connection.
[0040] In some embodiments, see Figure 1 and Figure 2 The antenna 300 includes multiple telescopic rods that are nested with each other. Different telescopic rods have different diameters. Among two adjacent telescopic rods, the thinner telescopic rod can be inserted into the thicker telescopic rod to achieve the change of the overall length of the antenna 300. When the multiple telescopic rods are fully extended, the length is greater than 500mm.
[0041] In some embodiments, the antenna 300 includes a plurality of mutually hinged folding rods, adjacent folding rods are connected by hinge shafts, and adjacent folding rods can be bent relative to each other as needed. When the folding rods maintain an angle of 0°, the antenna 300 has the shortest length. When the angle between the folding rods is 180°, the antenna 300 has the longest length, which is greater than 500 mm.
[0042] In some embodiments, the antenna 300 includes multiple detachable connecting rods, which are connected by threads. Different connecting rods can be connected end to end to change the length of the antenna 300. When three connecting rods are connected, the length of the antenna 300 is greater than 500 mm.
[0043] It should be noted that according to internal industry standards, the length of the antenna 300 is not less than 500 mm. Generally, the length of the antenna 300 is controlled to be slightly greater than 500 mm, which not only meets the standard requirements, but also does not make the antenna 300 too long and difficult to store. At the same time, the minimum diameter of the antenna 300 is generally greater than 2 mm.
[0044] Compared with the metal wire antenna 300, the antenna 300 in the present application is easy to adjust and store, and has a strong ability to resist deformation due to external forces.
[0045] In addition, the antenna 300 may also be a hard metal conductive rod. The antenna 300 does not need to be stored and can be stored together with the electric test pole without interfering with the electric test function.
[0046] Workflow: First, adjust the abutment 420 to the abutment state, and retract the end of the abutment 420 into the mounting sleeve 410. Then, insert the slot body 210 into the metal hook 100 so that the anti-slip teeth 211 cooperate with the groove 110 of the metal hook 100. Next, adjust the abutment 420 to the sliding state, and the slider in the slide groove releases the lock on the abutment 420. Under the action of the elastic member 430, the abutment 420 can move relative to the anti-slip teeth 211 and abut against the metal hook 100, completing the connection and fixation of the claw 200 and the metal hook 100, so that the claw 200 and the metal hook 100 maintain good electrical contact.
[0047] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
