[0023] With the continuous development of railway technology, the contact network engineering in railway traction power supply plays an increasingly important role. It is necessary to continuously improve the quality of contact network equipment through skylight maintenance operations to ensure a high level of bow-net relationship. In order to effectively eliminate the harm of induced electricity and mis-transmission of electricity on the contact network equipment to maintenance personnel, ground wires must be hung on the contact network at both ends of the maintenance range to achieve equal potential with the rails.

[0024] In recent years, incorrect operation sequence has frequently occurred during the ground wire hooking process, resulting in accidents of induced electric injuries and deaths. The present invention mainly develops intelligent grounding boots as a means of technological safety, combined with the improvement of the professional quality of operators, to fundamentally solve the problem of improper ground wire operation during the maintenance of contact network equipment, prevent the recurrence of induced electric injury accidents, and ensure the safety of life and property of maintenance personnel.

[0025] like Figure 1 to Figure 2 As shown, the present invention provides an intelligent grounding shoe with equipotential for a contact network or a power transmission line.

[0026] Specifically, by Figure 1Provided is an intelligent grounding shoe for contact network or power transmission line equipotential, comprising a grounding hook 1, a track 8 and a grounding hook 9 integrally formed at one end of the grounding hook 1; a clamping member 7 and a moving member 5 are slidably provided on the grounding hook 1, both of which can slide along the length direction of the grounding hook 1, and the track 8 is clamped between the grounding hook 9 and the clamping member 7. In order to stably clamp the handle 2, the grounding hook 9 and the clamping member 7 are provided with a card slot matching the shape of the track 8 on the opposite sides of the clamping member 7, the clamping member 7 and the moving member 5 are connected by an elastic structure, the handle 2 is rotatably arranged on the grounding hook 1, and a mounting shaft is installed on the part of the grounding hook 1 away from the grounding hook 9, and the handle 2 is sleeved on the mounting shaft. The handle 2 can be used as Figure 1 The latch pin shown in the figure is connected with the pin hole in a matching manner, and a slide rail matching with the outer wall of the mounting shaft can also be provided in the handle 2 to mount the shaft. It can slide in the slide rail and can be locked at any position in the slide rail. The sensing control module 3 is rotatably mounted on the moving part 5 through the connecting part 4, and the two ends of the connecting part 4 are rotatably connected to the handle 2 and the moving part 5 respectively. A connecting shaft 1 is mirror-set on the side of the moving part 5, and a connecting shaft 2 is mirror-set on the side of the handle 2. The two ends of the connecting part 4 are rotatably sleeved on the connecting shaft 1 and the connecting shaft 2 respectively, and the connecting shaft 2 is coaxially arranged with the mounting shaft. The handle 2 and the sensing control module 3 can be connected through a connecting mechanism, and the connecting mechanism is self-locking and fixed when the handle 2 is rotated to be vertical to the ground hook 1.

[0027] In the present invention, the handle 2 is divided into a connecting section, a self-locking section and a holding section. The connecting section is mounted on the mounting shaft through a mounting opening and is rotatably connected to the ground hook 1. The self-locking section is used to cooperate with the sensing control module 3 to be self-locked and fixed through a snap-on structure, while the holding section is used for the staff to hold and apply force.

[0028] Furthermore, as a specific embodiment of the present invention, the present invention provides an intelligent grounding shoe with equipotential of a contact network or a power transmission line.

[0029] Specifically, Figure 1 As shown, the elastic structure is a spring 6, which is located between the clamping member 7 and the moving member 5, and the spring 6 is slidably mounted on the ground wire hook 1. The spring 6 can slide along the length direction of the ground wire hook 1, and the ends of the spring 6 are respectively fixed on the opposite sides of the clamping member 7 and the moving member 5.

[0030] Specifically, the connecting mechanism includes a buckle 11 integrally formed on the handle 2, and a recess 10 for inserting the buckle 11 is provided at the upper side of the sensing control module 3. The buckle 11 is U-shaped, and a self-locking component is provided in the recess 10 for selectively fixing the buckle 11 in the recess 10. When the handle 2 is rotated to be perpendicular to the ground hook 1, the buckle 11 is just inserted into the recess 10, and self-locking is completed by the self-locking component in the recess 10.

[0031] In addition, the sensing control module 3 also includes a shell, and a protrusion 12 is provided in the middle part of the handle 2 near the sensing control module 3. The distance between the handle 2 above and below the side of the protrusion 12 and the sensing control module 3 is larger than the distance between the protrusion 12, and sufficient space can be reserved for the handle 2 to rotate.

[0032] Furthermore, the self-locking component is an electromagnetic lock, and the self-locking component is an electromagnetic lock, which includes a magnetic metal element arranged in the recess 10, such as a nickel-titanium wire, wherein: in the power-off state, the magnetic metal element (nickel-titanium wire) is connected to the buckle 11, and the electromagnetic lock is locked; in the power-on state, the magnetic metal element (nickel-titanium wire) contracts and disconnects from the buckle 11, and the electromagnetic lock is unlocked. A mechanical lock may also be used, with a movable lock tongue provided in the recess 10. After the buckle 11 is inserted into the recess 10, the lock tongue passes through the buckle 11 to restrict the buckle 11 from being separated from the recess 10 to complete self-locking. The specific structure of the mechanical lock may be implemented using relatively mature existing technologies, or may be self-locking by means of electric drive in conjunction with a mechanical structure. For example, a mounting groove may be provided on the side wall of the recess 10, in which an electric telescopic rod and other structures may be installed, and a bolt may be fixedly installed at the movable end of the electric telescopic rod, and a socket for inserting the bolt may be provided on the side wall of the recess 10 opposite to the mounting groove. After the buckle 11 is inserted into the recess 10, self-locking may be completed by controlling the extension of the electric telescopic rod.

[0033] Working principle: After the induction control module 3 receives the external signal, the signal is identified, and the grounding boot is in action. The connecting part 4, handle 2, movable part 5 and ground hook 1 constitute a connecting rod mechanism. When the handle 2 is turned, the movable part 5 moves left and right along the long diameter direction of the ground hook 1. At the same time, the induction control module 3 and the handle 2 rotate relative to each other around the axis of the connecting rod's rotating shaft-the installation axis. When the grounding hook 9 and the clamping part 7 clamp the track 8, the handle 2 and the induction control module 3 are locked. The handle 2 can be locked by mechanical control or electromagnetic induction, and has the function of self-locking when the power is off.

[0034] The grounding shoe is inserted into the lower surface of the track 8, and the handle 2 rotates around the specified position of the grounding hook 1; the connecting member 4 is hinged to the handle 2, and the connecting member 4 is hinged to the moving member 5. The grounding hook 1 passes through the moving member 5, and the grounding hook 1 serves as a linear guide for the moving member 5. When the handle 2 is rotated, the moving member 5 slides relative to the grounding hook 1, realizing the conversion of rotational motion into linear motion. The wire diameter of the spring 6 is larger than the diameter of the grounding hook 1 and smaller than the diameter of the inscribed circle of the contact surface with the moving member 5.

[0035] The other side of the spring 6 is in working state and fits with the clamping piece 7, and the clamping piece 7 is in working state and fits with the track 8. Because the clamping piece 7 is subjected to the reaction force of the spring 6 when the spring 6 is in working state, it can achieve flexible fit with the track 8, thus ensuring the equipotential of the contact network or power transmission line and the track, i.e. grounding. When the handle 2 is rotated at the right angle and the clamping piece 7 and the grounding hook 9 just clamp the track 8, the induction control module 3 just locks the handle 2 to achieve quick installation.

[0036] When a signal is sent out from the outside, which also has an identity recognition function, the sensing control module 3 receives the signal and unlocks the handle 2, rotates the handle 2 counterclockwise, and the clamping member 7 quickly moves away from the guide rail 8, and the smart grounding shoe can be removed at this time.

[0037] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
