[0023] Embodiment 1

[0024] The present embodiment provides a portable slotting sampling device for underground, specifically as follows Figures 1-4 、 Figure 7As shown, including support frame, the support frame includes support frame crossbeam 102 and support frame vertical beam 101 installed at both ends of support frame crossbeam 102 respectively, the support frame crossbeam 102 is provided with pulley groove 119, locking groove 120; hoisting assembly, the hoisting assembly is arranged on the support frame, for hoisting pick 103; the hoisting assembly includes rotating shaft 110, locking pin 107, locking pin 107 is provided with threaded groove 111, rotating shaft 110 is inserted in support frame crossbeam 102, a plurality of through holes are arranged radially on rotating shaft 110, threaded groove 111 is threadedly connected with the through hole, locking pin 107 slides in locking groove 120, pulley 106 is rotatably connected on rotating shaft 110, pulley 106 rolls in pulley groove 119; one take-up roller 105 is installed at both ends of rotating shaft 110 respectively, and a rocker is installed on one take-up roller 105; pulley cable 104 is wound on take-up roller 105, and hook 116 is arranged at the end of pulley cable 104; the hoisting assembly further includes a lifting ring for fixing pick 103, the lifting ring includes a plurality of connecting arc plates 117, a hanging ring 121 is installed on one connecting arc plate 117, the hanging ring 121 is hung on hook 116, and adjacent connecting arc plates 117 are connected by connecting bolts 118; pick 103 is used for grooving sampling on the wall surface.

[0025] Before construction, the support frame crossbeam 102 is pressed down, so that the two support frame vertical beams 101 are inserted into the ground, then the lifting ring installed on the pick 103 is hung on the hook 116, and then the locking pin 107 is rotated and pulled out, at this time, the rocker is manually rocked, so that the take-up roller 105 drives the rotating shaft 110 to rotate, when the take-up roller 105 rotates, the pulley cable 104 starts to release, and the pick 103 starts to descend, when the height of the pick 103 moves to the position required for grooving, stop rocking the rocker, and the locking pin 107 is inserted into the through hole on the rotating shaft 110 and rotated, so that the locking pin 107 is fixed with the rotating shaft 110, at this time, because the support frame crossbeam 102 limits the rotating shaft 110 and the locking pin 107 is pressed in the locking groove 120, so that the take-up roller 105 cannot rotate when it is pulled by the pulley cable 104, and the multiple-point support of the two pulley cables 104 ensures that the pick 103 is in a horizontal state, then the worker moves the pick 103 to one end of the support frame crossbeam 102, and then starts the pick 103 and drags the pick 103 to move, at this time, the pick 103 will groove on the wall surface and sample; when the pick 103 is dragged to move, the pulley 106 rolls on the pulley groove 119, ensuring that the pulley cable 104 is always in a vertical state, that is, ensuring the stability of the height of the pick 103.

[0026] Through setting the hoisting assembly, the ripper 103 is separated from the support frame cross beam 102, the object around the ripper 103 is reduced, the space around the ripper 103 is increased, and the staff can carry out diversified operation; meanwhile, when the height of the ripper 103 is adjusted, only the rocker needs to be shaken, which is more rapid compared with the traditional method of adjusting the height of the vertical beam 101 of the two support frames.

[0027] Embodiment 2

[0028] This embodiment is further extended on the basis of the above-mentioned embodiments, and specifically as shown in Figure 5 、 Figure 6 The support frame vertical beam 101 is rotatably connected to the connecting block 113 on the support frame cross beam 102, and the support frame vertical beam 101 is provided with an inner hexagonal hole at one end and a tapered surface at the other end, and the tapered surface is provided with a spiral digging groove 112.

[0029] When the support frame is installed, the two support frame vertical beams 101 will inevitably have different insertion depths into the ground. At this time, the level on the support frame cross beam 102 can be directly observed, but further pressing down may result in excessive insertion. Therefore, the staff can use a wrench to twist the inner hexagonal hole of the support frame vertical beam 101, so that the spiral digging groove 112 is rotated into the ground. At this time, the rotation amount is small, which is suitable for fine adjustment, until the support frame cross beam 102 is leveled. In this way, the installation posture of the support frame is adjusted to ensure the accuracy of the notch sampling.

[0030] The other parts of this embodiment are the same as those of the above-mentioned embodiments and will not be described again.

[0032] This embodiment is further extended on the basis of the above-mentioned embodiments, and specifically as shown in Figure 5 The connecting block 113 is provided with a positioning block 114, and the positioning block 114 cooperates with the support frame cross beam 102 to adjust the position of the support frame vertical beam 101.

[0033] The support frame vertical beam 101 is installed on the support frame cross beam 102 through the connecting block 113, so that the support frame vertical beam 101 can be folded when not in use, reducing the space occupation. When in use, the support frame vertical beam 101 is actuated, so that the positioning block 114 is pressed on the support frame cross beam 102. The positioning block 114 is used to make the support frame vertical beam 101 in a vertical state, preventing the two support frame vertical beams 101 from being inserted into the ground with increased resistance due to non-parallelism.

[0034] The other parts of this embodiment are the same as those of the above-mentioned embodiments and will not be described again.
