Abstract
The utility model discloses a kind of cable testing bridge grounding clamp, it is made up of cover and temperature sensor at the bottom of hollow screw, locking nut, connecting ring, upper compressing tablet, lower sheeting, screw thread; Upper compressing tablet and lower sheeting are between the screw head and locking nut of hollow screw, connecting ring is pressed between locking nut and lower sheeting, overlap the mode that is threaded connection at the bottom of described screw thread to be arranged on bottom hollow screw and cover bottom surface at the bottom of screw thread has wire hole, described temperature sensor is positioned at hollow screw and its holding wire is extended to outside cover at the bottom of screw thread by described wire hole, and described connecting ring connects earth connection.This cable testing bridge grounding clamp is integrated with a temperature sensor, and temperature sensor has measurement function, therefore makes grounding clamp like never before be provided with the function of measurement, like this, just without the need to perforate mounting temperature sensor extraly on crane span structure, more convenient during making.
Description
Technical field
The utility model relates to a kind of cable testing bridge, especially a kind of cable testing bridge grounding clamp.
Background technology
Cable trough type bridge frame frame is aloft for placing cable.Existing cable trough type bridge frame Problems existing is, electric cable heating easily produces high temperature, and cause short circuit or the accident such as on fire, people are provided with blower fan on cable trough type bridge frame for this reason, blower fan is made and is linked with the temperature sensor in cable trough type bridge frame, blower fan action during temperature height.This cable trough type bridge frame, by independent perforate set temperature transducer, is installed inconvenient, and temperature sensor protrudes, and to be arranged on crane span structure content easily damaged.
In addition: grounding clamp is the part of cable trough type bridge frame, it is for leading away the electrostatic on crane span structure, and makes crane span structure pass to raising fail safe mutually with the earth.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of cable testing bridge grounding clamp with temp sensing function.
Scheme of the present utility model is:
A kind of cable testing bridge grounding clamp, it is made up of cover and temperature sensor at the bottom of hollow screw, locking nut, connecting ring, upper compressing tablet, lower sheeting, screw thread; Upper compressing tablet and lower sheeting are between the screw head and locking nut of hollow screw, connecting ring is pressed between locking nut and lower sheeting, overlap the mode that is threaded connection at the bottom of described screw thread to be arranged on bottom hollow screw and cover bottom surface at the bottom of screw thread has wire hole, described temperature sensor is positioned at hollow screw and its holding wire is extended to outside cover at the bottom of screw thread by described wire hole, and described connecting ring connects earth connection.
This cable testing bridge grounding clamp, the bottom surface of crane span structure is clamped between compressing tablet and lower sheeting, and earth connection is connected with the earth or wall, and holding wire is for exporting measuring-signal.
The beneficial effects of the utility model are:
This cable testing bridge grounding clamp is integrated with a temperature sensor, temperature sensor has measurement function, therefore grounding clamp is made like never before to be provided with the function of measurement, like this, just without the need to perforate mounting temperature sensor extraly on crane span structure, more convenient during making, on the other hand, temperature sensor is limited in hollow screw, and hollow screw plays a protective role to temperature sensor, makes temperature sensor not easily damaged; Moreover screwing on of cover at the bottom of screw thread can regulate the height of temperature sensor in hollow screw, to regulate measurement precision with screwing off.
The further improvement project of the utility model is: the screw head end face of described hollow screw is provided with ventilation slot;
The further improvement project of the utility model is: the opposite face of described upper compressing tablet and lower sheeting is interval with raised line.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 cable testing bridge grounding clamp;
Fig. 2 is the vertical view of embodiment 2 hollow screw;
Fig. 3 is the structural representation of embodiment 3 cable testing bridge grounding clamp.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the cable testing bridge grounding clamp described by the present embodiment, it is made up of cover 6 and temperature sensor 7 at the bottom of hollow screw 1, locking nut 2, connecting ring 3, upper compressing tablet 4, lower sheeting 5, screw thread; Upper compressing tablet 4 and lower sheeting 5 are between the screw head and locking nut 2 of hollow screw 1, connecting ring 3 is pressed between locking nut 2 and lower sheeting 5,6 modes that are threaded connection of overlapping at the bottom of described screw thread to be arranged on bottom hollow screw 1 and to overlap 6 bottom surfaces at the bottom of screw thread has wire hole 8, described temperature sensor 7 is positioned at hollow screw 1 and its holding wire 11 is extended to outside cover 6 at the bottom of screw thread by described wire hole 8, and described connecting ring 3 connects earth connection 12.Temperature sensor 7 adopts PT100 or PT1000 thermal resistance.
This cable testing bridge grounding clamp, the bottom surface of crane span structure is clamped between compressing tablet 4 and lower sheeting 5, and earth connection 12 is connected with the earth or wall, and holding wire 11 is for exporting measuring-signal.This cable testing bridge grounding clamp is integrated with a temperature sensor 7, temperature sensor 7 has measurement function, therefore grounding clamp is made like never before to be provided with the function of measurement, like this, just without the need to perforate mounting temperature sensor 7 extraly on crane span structure, more convenient during making, on the other hand, temperature sensor 7 is limited in hollow screw 1, and hollow screw 1 pair of temperature sensor 7 plays a protective role, and makes temperature sensor 7 not easily damaged; Moreover, overlap 6 screw on and can regulate the height of temperature sensor 7 in hollow screw 1, to regulate measurement precision with screwing off at the bottom of screw thread.
Embodiment 2:
As shown in Figure 2, the cable testing bridge grounding clamp described by the present embodiment, as different from Example 1: the screw head end face of described hollow screw 1 is provided with ventilation slot 9; The existence of ventilation slot 9 makes temperature sensor 7 contact with air in crane span structure better, and while improving measurement precision, hollow screw 1 does not lose protective effect again.
Embodiment 3:
As shown in Figure 3, the cable testing bridge grounding clamp described by the present embodiment, as different from Example 1: the opposite face of described upper compressing tablet 4 and lower sheeting 5 is interval with raised line 10.The effect of raised line 10 is to clamp crane span structure bottom surface better.
Above-described embodiment is only to design of the present utility model explanation for example, and significantly, the protection range of this patent is not limited to above-described embodiment.
The various equivalent modifications or supplementary that those skilled in the art do above-described embodiment, all should fall into the protection range of this patent.
