Abstract
The utility model discloses an anchor rod and anchor cable strain detector, which comprises a sensor body and is characterized by also comprising a connecting rod and a signal transmitter with a light control circuit, wherein the signal wire of the sensor body is connected with a pressure signal transmitter after passing through the connecting rod; and the connecting rod and the sensor body are fastened and connected through a nut. When the anchor rod and anchor cable strain detector is used and the anchor rod or anchor cable strain value is changed, the pressure signal transmitter visually and clearly display the current pressure value. When the anchor rod and anchor cable strain detector is in operation, the magnitude of the current strain value can be visually displayed only by mine lamp illumination to arouse the alertness of underground staffs and avoid the accidents happening.
Description
Technical field
The utility model relates to the instrument of colliery downhole detection anchor pole, anchor cable stress.
Background technology
At present, anchor pole or the anchor cable tension gauge device that use in process of production in most collieries, all be that sensor body is installed on anchor pole or the anchor cable, reserve signal cable on the sensor body, in the time of need carrying out the stress detection, the staff adopts utility appliance to obtain the current pressure stress value by signal cable and sensor body communication.The shortcoming of this using method is: 1. the demonstration of anchor pole or anchor cable stress value is not directly perceived, just can learn current stress value when having only the staff to operate.2. owing to structural restriction, the communication cable length of reservation differs, and produces inconvenient.3. staff's inconvenient operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, makes improvements, and designs a kind of anchor pole, anchor cable tension gauge.
The technical solution of the utility model is: it comprises the existing sensors body, it is characterized in that, it also comprises connecting link and has the signal transmitting device of light-operated circuit, the signal wire of sensor body passes connecting link and is connected with the pressure signal transmitter, and connecting link and sensor body are fastenedly connected by nut.
During use, sensor is installed on gaging hole mouth place, the pressure signal transmitter is close on the top board in tested tunnel, and makes inspection surface down.During work, sensor is transferred to the pressure signal transmitter with the pressure signal that records, and by the pressure signal transmitter voltage signal is converted to the current pressure value, and by light-operated circuit, display window shows the current pressure value under the situation of artificial lighting.
Good effect of the present utility model is:
When 1, using, when anchor pole or anchor cable stress value change, the pressure signal transmitter intuitively shows current pressure value, visual clear display.
Only need when 2, operating intuitively to show current stress value size, cause personnel in the pit's vigilance, avoid having an accident with the mine lamp irradiation.

Fig. 2 is the upward view of Fig. 1;
Fig. 3 is user mode figure of the present utility model.
Marginal data: 1-pressure signal transmitter, 2-connecting link, 3-sensor body, 4-nut, 5-anchor pole or anchor cable, 6-top board, 7-gaging hole.
Embodiment
As depicted in figs. 1 and 2, it comprises existing sensor body 3, and the signal wire of sensor body 3 passes connecting link 2 and is connected with the pressure signal transmitter 1 that has light-operated circuit, and connecting link 2 is fastenedly connected by nut 4 with sensor body 3;
(see figure 3) during use is installed on sensor body 3 on the anchor pole or anchor cable 5 at place, gaging hole 7 apertures, and pressure signal transmitter 1 is close on the top board 6 in tested tunnel, and makes inspection surface down.During work, sensor is transferred to pressure signal transmitter 1 with the pressure signal that records, and by pressure signal transmitter 1 voltage signal is converted to the current pressure value, and by light-operated circuit, display window shows the current pressure value under the situation of illumination.
