Embodiment 1

[0049] Embodiment 1, a kind of mobile type inclinometer probe detachment fishing device, such as Figure 4 As shown, the connecting rod 2 is included, the lower end of the connecting rod 2 is provided with a salvage shovel 1, and the connecting rod 2 can drive the salvage shovel 1 to move up and down and rotate.

[0050] Said fishing shovel 1 includes a guide groove body connected with the connecting rod 2 , and the guide groove body includes a main groove 101 , a connecting groove 103 and a catcher groove 104 sequentially from top to bottom. The length of the guide groove is preferably 2.0 to 2.5 meters. The material is straight and has no distortion, and the corners are smooth and smooth. Salvage shovel 1 movement direction. The length of the connecting guide groove 103 is 30-50 cm, and the length of the catcher guide groove 104 is 5 cm. The guide groove body is an angle steel, and part of the side wall is cut off from the angle steel to form the connecting guide groove 10...

Embodiment 2

[0060] Embodiment 2, a salvage method for a mobile inclinometer probe detached salvage device, comprising the following steps:

[0061] ① On-site preparation: When the mobile inclinometer 3 is detached from the tube, first tighten the cable 322 and fix it to prevent the upper and lower guide wheel groups from continuing to slide down, and wait for processing; on-site check whether the cable 322 is straight and damaged, Calculate the distance between the upper guide wheel set and the lower guide wheel set of the inclinometer probe 31 from the upper nozzle of the inclinometer tube 4 through the depth data marked on the cable 322, and confirm that the lower guide wheel set of the mobile inclinometer 3 is off the tube and the upper guide wheel If the wheel set is not detached from the tube, calculate the detachment depth of the lower guide wheel set; finally, find out the direction of the upper wheel of the upper guide wheel set and the lower guide wheel set;

Abstract

The invention discloses a movable inclinometer probe pipe-off fisher and a fishing method thereof. The technical problem that an existing inclinometer probe fishing device cannot fish a pipe-off inclinometer probe is solved. The movable inclinometer probe pipe-off fisher comprises a connecting rod, wherein a fishing shovel is arranged at the lower end of the connecting rod and comprises a guide groove body connected with the connecting rod; the guide groove body sequentially comprises a main guide groove, a connecting guide groove and a catcher guide groove from top to bottom; the catcher guide groove is of a short side wall structure; the side wall of the connecting guide groove is of a smooth arc-shaped structure connecting the side wall of the main guide groove and the side wall of thecatcher guide groove; the catcher guide groove is arranged in an arc shape in the direction deviating from the external corner of the guide groove body and deviates from the outer side of the externalcorner of the main guide groove by 15-20mm; and a groove is formed in the end of the catcher guide groove. The movable inclinometer probe pipe-off fisher is wide in application range, small in economic input, easy to manufacture, convenient to install, safe and rapid to operate, large in fishing depth, easy to operate, convenient to disassemble, transport and store and capable of being repeatedlyused.

Description

technical field [0001] The invention relates to the technical field of salvage devices for mobile inclinometers, in particular to a salvage device for removing pipes of mobile inclinometer probes and a fishing method thereof. Background technique [0002] Safety monitoring is becoming more and more important in engineering operation management. Borehole inclinometer monitoring is a reliable method for deep displacement monitoring. Its main task is to use mobile inclinometers to monitor the internal data of the inclinometer, such as figure 1 As shown, the mobile inclinometer 3 includes three parts: an inclinometer probe 31, an inclinometer reel 32 and a reading instrument 33. The inclinometer reel 32 includes a reel base 321 and a cable 322, wherein the inclinometer The probe 31 includes a probe main body 316, the upper end of the probe main body 316 is connected to the cable 322 through a male screw 315 and a female screw 323, the probe main body 316 is provided with an uppe...
