Description

Technical Field

[0001] The utility model belongs to the technical field of quality acceptance, and in particular relates to an acceptance device for concealed engineering in underground mines. Background Art

[0002] Due to the influence of geological engineering conditions of ore bodies and surrounding rocks, underground metal mines often need to anchor nets for safety support of some tunnel roofs and side walls during mining, cutting, medium-deep hole construction and blasting. At the same time, hidden engineering acceptance of anchor nets should be carried out in time before commercial concrete spraying. The use of tape measures can only be used to inspect the depth of anchor support on the side walls of the tunnels, and the depth of anchor support on the tunnel roof cannot be effectively measured and inspected. At the same time, the inner diameter of the root of the anchor and the degree of deformation of the anchor cannot be accurately measured, which has a certain impact on the acceptance quality of the overall hidden engineering. When using tape measures for acceptance, the tape measures sometimes get stuck at the root of the anchor, affecting the acceptance progress. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0032] Example 1

[0033] The underground mine concealed engineering acceptance device comprises a measuring rod 1, on which a scale is engraved, and a flaw detection ball 2 matching the inner diameter of the hollow part of the anchor rod is arranged at the measuring end of the measuring rod 1.

[0034] The device measures the anchor rod by means of a measuring rod 1 engraved with a scale, thereby effectively solving the problem that the anchor rod support depth of the tunnel roof cannot be effectively measured and accepted; a flaw detection ball 2 matching the inner diameter size of the hollow part of the anchor rod is provided at the measuring end of the measuring rod 1. By using the flaw detection ball 2, the inner diameter specification of the anchor rod can be quickly checked and whether the anchor rod is deformed can be quickly determined, thereby improving the acceptance efficiency and also improving the accuracy of the acceptance.

[0035] A handle 3 is provided on the measuring rod 1 at the gripping end of the measuring rod 1, which can more conveniently push the measuring rod 1 into the root of the anchor rod that has been drilled into the rock mass, and also can more conveniently pull the measuring rod 1 out of the anchor rod, thereby improving the measurement efficiency.

[0036] Example 2

[0037] The measuring rod 1 includes a multi-section rod body 11, and a folding device 4 is arranged between adjacent rod bodies 11. The multi-section rod body 11 can be folded by the folding device 4. The folding device 4 includes a connecting piece 41. The connecting pieces 41 are evenly distributed and respectively arranged inside adjacent rod bodies 11, and are used to connect adjacent rod bodies 11. Notches that cooperate with the connecting pieces 41 are arranged on the rod bodies 11. First mounting holes 42 are arranged on the connecting pieces 41 located in adjacent rod bodies 11, and second mounting holes that cooperate with the first mounting holes 42 are respectively arranged on the adjacent rod bodies 11. Screws 43 are inserted in the first mounting holes 42 and the second mounting holes. One end of the screw 43 is screwed to the connecting piece 41, and the rod body 11 can rotate around the screw 43.

[0038] The measuring rod 1 adopts a segmented acceptance rod body 11 design, and a folding device 4 is provided at the connection between adjacent rod bodies 11, so that the device can be folded and convenient to carry.

[0039] The ends of adjacent rod bodies 11 are designed to be semicircular, which effectively avoids interference between adjacent rod bodies 11 when the measuring rod 1 is folded.

[0040] When the adjacent rod bodies 11 rotate to a straight line state, the end surfaces of the adjacent rod bodies 11 can abut against each other.

[0041] Example 3

[0042] A locking device 5 is provided between adjacent rod bodies 11. When the adjacent rod bodies 11 rotate to a straight state, the locking device 5 locks the adjacent rod bodies 11 to prevent the adjacent rod bodies 11 from rotating, thereby ensuring the accuracy of measurement when the measuring rod 1 measures the anchor depth.

[0043] The locking device 5 comprises a locking frame 51 , which is arranged at one end of one of the rods 11 of any adjacent rods 11 , and a locking piece 53 is slidably arranged on the locking frame 51 , and a fixing mechanism and a locking mechanism are arranged on the locking piece 53 .

[0044] The fixing mechanism includes a latch tooth 52 arranged on the locking frame 51 and a push button 54 arranged on the locking plate 53 and cooperating with the latch tooth 52. The push button 54 is fixedly arranged on the locking plate 53, so that the operator can push the locking plate 53 to slide in the slideway of the locking frame 51. The push button 54 is provided with an elastic pin cooperating with the latch tooth 52. When the push button 54 is pushed, the elastic pin is in a retracted state, and the push button 54 pushes the locking plate 53 to slide in the slideway of the locking frame 51. When the push button 54 stops being pushed, the elastic pin will rebound under the action of the elastic force and cooperate with the groove between the latch teeth 52, so that the push button 54 is firmly stuck in the slideway.

[0045] The locking mechanism includes a locking hole 55 arranged on the locking plate 53, and one end of another rod body 11 of the adjacent rod bodies 11 is provided with a third mounting hole matching the locking hole 55. The push button 54 is pushed to slide the locking plate 53 to the corresponding position of the locking hole 55 and the third mounting hole. At this time, the push button 54 is stopped, and the fixing screw 43 is screwed into the locking hole 55 and the third mounting hole to fix the adjacent rod bodies 11, effectively preventing relative rotation between the rod bodies 11 of the measuring rod 1, thereby ensuring the accuracy of the measurement during measurement.
