[0028] Example

[0029] In the prior art, the drill rod sensing device of current intelligent drilling equipment has a complex and bulky structure. Due to the complex working structure, the risk of sensor damage is high and the overall failure rate is high. In addition, due to structural limitations, its positioning accuracy is poor and cannot meet the current requirements for underground coal mine construction.

[0030] See also Figure 1-3 The present invention provides a technical solution: a flexible sensing device for a drilling rig, comprising: a contact block 1, a sensing frame 2, a movable shaft seat 3, a connecting shaft block 4, a proximity switch 5 and a mounting frame 6, and adopts a mechanically coordinated electrical induction working structure. The sensing device has a simple and compact structure and a small installation volume, which can effectively save installation space. In addition, thanks to the small structure volume, the device is flexibly arranged and easy to use and install, and has good installation convenience. The contact block 1 is in direct contact with the sensing object, and the contact block 1 can be adjusted and installed on the upper part of the sensing frame 2. Specifically, as shown in the attached Figure 1 As shown, in order to facilitate the installation and adjustment of the contact block 1, an adjusting screw hole is provided on the top of the sensing frame 2, and an adjusting stud is provided at the lower part of the contact block 1. The lower end of the adjusting stud is threadedly connected to the inner side of the adjusting screw hole. The distance between the sensor and the detection body is adjustable. The position of the contact block 1 can be flexibly adjusted according to the installation and positioning requirements, which can effectively improve the flexibility of the device. In order to facilitate the locking limit of the adjusting stud after adjustment, a locking nut is installed in the middle of the adjusting stud.

[0031] The mounting frame 6 is used for mounting support of the sensing device, such as the attached Figure 2As shown, in order to facilitate the flipping installation of the sensing frame 2, a flipping slot is provided on the mounting frame 6, and a flip connecting block is fixedly installed on the upper rear part of the sensing frame 2, and the flip connecting block is movably fitted and installed on the inner side of the flipping slot to form a flipping connection structure. In order to realize fixed-axis rotation support, a connecting shaft column is provided on the upper part of the mounting frame 6, and the connecting shaft column passes through the upper part of the mounting frame 6 and is plugged and installed with the shaft hole provided in the middle part of the flip connecting block. The sensing frame 2 is installed on the upper part of the mounting frame 6 by fixed-axis flipping through the connecting shaft column. After the upper part is subjected to force, it can perform fixed-axis flipping movement along the connecting shaft column, changing the traditional vertical detection surface detection of the proximity switch to parallel detection surface detection, reducing the risk of impact damage to the proximity switch 5, and increasing the effective detection distance of the proximity switch 5 from 3mm to 15mm, effectively increasing the detection distance.

[0032] In order to facilitate the connection and installation of the proximity switch 5, an induction mounting seat is provided at the front of the mounting frame 6. Figure 2 As shown, the induction mounting base is fixedly installed in the middle of the front side of the mounting frame 6, and the induction mounting base is used for connecting and installing the proximity switch 5, as shown in the attached Figure 1 As shown, in order to facilitate the connection and installation of the proximity switch 5, a sensor mounting port is provided at the end of the sensing mounting seat, and the proximity switch 5 is fixedly installed on the inner side of the sensor mounting port for positioning detection of the sensing object. In order to realize the value detection work, a detection swing arm is provided on the lower side of the sensing frame 2, and the detection end of the proximity switch 5 is facing the side of the detection swing arm.

[0033] The movable shaft seat 3 and the connecting shaft block 4 are used for the flipping guidance and limiting of the induction frame 2. Figure 1 As shown, the movable shaft seat 3 is fixedly installed on the upper part of the connecting shaft block 4. In order to facilitate installation and connection, an shaft hole is provided in the middle part of the movable shaft seat 3, and a movable shaft column is installed inside the shaft hole. In order to connect and install with the connecting shaft block 4, a connecting shaft seat is fixedly installed on the upper bottom side of the sensing frame 2, and the connecting shaft block 4 is hingedly installed with the connecting shaft seat through the movable shaft column to realize the linkage connection between the upper part and the sensing frame 2. In order to connect and install with the sensing mounting seat, an engaging notch is provided at the lower part of the connecting shaft block 4, and the lower part of the connecting shaft block 4 is movably engaged with the middle part of the sensing mounting seat through the engaging notch, and a fixed shaft column is installed in the shaft hole provided at the lower part of the connecting shaft block 4, and an installation shaft hole is opened through the middle part of the sensing mounting seat, and the lower part of the connecting shaft block 4 is hingedly installed with the middle part of the sensing mounting seat through the fixed shaft column to realize the linkage connection with the lower sensing mounting seat, as shown in the attached figure. Figure 3 As shown, after the induction is completed, the rear part of the connecting shaft block 4 conflicts with the mounting frame 6, and a mechanical limit is added on the basis of the electrical signal detection of the proximity switch 5. The mechanical limit is added on the basis of the electrical detection, and the detection accuracy of the action position is improved. The conflict limit of the connecting shaft block 4 can avoid collision damage to the proximity switch 5, thereby ensuring the stability and safety of the sensing device.

[0034] According to the working principle or structural principle, the sensing device is installed at the corresponding position on the upper part of the intelligent drilling equipment. After installation, the position of the contact block 1 is adjusted according to the installation positioning detection needs. During adjustment, the elongation of the adjusting stud is changed by the knob. After the adjustment is completed, the adjusting stud is fixed and the locking nut on the upper part is tightened to lock the adjusted contact block 1 to limit the position, and the adjustment operation of the contact block 1 is completed. When the drilling equipment is installing and removing the drill rod, the object to be detected approaches and presses the contact block 1 downward. The contact block 1 is pushed through contact, and the downward pressure cooperates with the linkage guide of the movable shaft seat 3 and the connecting shaft block 4 to make the sensing frame 2 flip downward. During the flipping process, the detection swing arm on the side of the sensing frame 2 flips down and detects the displacement through the proximity switch 5 to realize the positioning detection of the detection object. When the sensing frame 2 is detected by the proximity switch 5, the connecting shaft block 4 reaches the locking position, as shown in the attached Figure 3 As shown, at this time, the rear part of the connecting shaft block 4 contacts the front part of the mounting frame 6 to form a mechanical limit, thereby ensuring the stability and safety of the sensing device and completing the detection work.

[0035] In summary, the detection principle is optimized, and the traditional vertical detection surface detection of the proximity switch is changed to parallel detection surface detection, which reduces the risk of impact damage to the proximity switch 5 and increases the effective detection distance of the proximity switch 5 from 3mm to 15mm, effectively improving the detection distance and reducing the risk of sensor damage and failure rate. An adjustable contact block 1 is adopted, and the distance between the sensor and the detection body is adjustable. A mechanical limit is added on the basis of the electrical signal detection of the proximity switch 5, and a mechanical limit is added on the basis of electrical detection, so that the detection accuracy of the action position is improved. In addition, a mechanically coordinated electrical induction working structure is adopted, and the sensing device has a simple and compact structure with a small installation volume, which can effectively save installation space, and thanks to the small structure volume, the device layout is flexible and easy to use and install, and has good installation convenience.
