Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Example 1

As shown in fig. 1, 2, 3 and 4, a terminal anchor clamp loosening detection device is provided, where a terminal anchor clamp 1 is used for anchoring a thread 2, and includes a transmitting end 3 and a receiving end 4 that can be distributed on two sides of the end of the thread 2, where the receiving end 4 can receive a signal transmitted by the transmitting end 3 under the condition that a wireless cable 2 is shielded.

In this embodiment, the signal may be, but is not limited to, an infrared signal, and the transmitting terminal 3 and the receiving terminal 4 together form an infrared sensor. Of course, other sensors capable of detecting the presence of the wireless cable 2 may be used. The thread 2 may be, but is not limited to, a carrier rope, a contact line, and is not limited herein.

The transmitting end 3 periodically transmits signals outwards, as shown in fig. 1, the receiving end 4 cannot receive signals due to the blocking of the clue 2, and if the receiving end 4 continuously does not receive signals, the receiving end is in a continuous non-triggering state, and the terminal anchor wire clamp 1 is proved to work normally without potential safety hazards. As shown in fig. 2, when the thread 2 is loosened, a part of the thread can slide out, at this time, the head of the thread 2 is shortened, no shielding exists between the transmitting end 3 and the receiving end 4, the signal transmitted by the transmitting end 3 is received by the receiving end 4, so that the terminal anchor wire clamp 1 is abnormal and needs to be replaced or overhauled.

Example two

The terminal anchor clamp loosening detection device needs to work normally under the high voltage 25000V, and electromagnetic interference can influence the precision and accuracy of the sensor, so that measures are needed to isolate damage caused by the high voltage to the sensor, and electromagnetic interference is reduced.

Based on this, on the basis of the first embodiment, the transmitting end 3 and the receiving end 4 are respectively wrapped with a high voltage resistant insulating material.

The high voltage resistant insulating material can be glass fiber reinforced epoxy resin, silicone rubber, polyimide film or the like. Different high voltage resistant insulating materials have differences in performance, price and use conditions, and the selection of suitable high voltage resistant insulating materials should be evaluated and selected according to specific application occasions and requirements.

It should be noted that, in addition to shielding the sensor with a high voltage resistant insulating material, a method such as an anti-interference circuit may be used.

Example III

On the basis of the first embodiment or the second embodiment, as shown in fig. 1 and 2, the transmitting end 3 and the receiving end 4 are installed on the terminal anchoring wire clamp 1, and various installation modes are provided, for example, two grooves are oppositely arranged on the inner side of the U-shaped wire clamp body 11 of the terminal anchoring wire clamp 1, and the transmitting end 3 and the receiving end 4 are respectively installed in the corresponding grooves.

By adopting the mode in the embodiment, unnecessary parts are not required to be additionally arranged during production, and the cost is saved as much as possible.

Example IV

The difference from the third embodiment is that, as shown in fig. 3 and 4, the transmitting end 3 and the receiving end 4 are mounted on a mounting member 5 fixed relative to the terminal anchor clamp 1, and the mounting member 5 may be mounted on the terminal anchor clamp 1 or on another fixed body. As shown in fig. 3 and 4, the mounting member is formed by buckling two U-shaped members, and can be sleeved outside the terminal anchor clamp 1.

By adopting the mode in the embodiment, the terminal anchor wire clamp loosening detection device can be conveniently installed on the existing terminal anchor wire clamp 1 without changing the structure of the existing terminal anchor wire clamp, and the existing terminal anchor wire clamp 1 is conveniently modified.

Example five

As shown in fig. 1 and 2, the terminal anchor clamp loosening detection device further comprises a communication module 6 connected with the receiving end 4, and the receiving end 4 is used for triggering the communication module 6 to send out an alarm outwards when receiving a signal.
