[0060] Compared with the prior art, the test device for an anchor rod drilling machine provided by the embodiments of the application has the following beneficial effects:

[0061] The anchor rod drilling machine testing device provided by the embodiment of the present application comprises a test bench 10, a guide frame 20 and a displacement driving assembly. The top of the test bench 10 is provided with a supporting assembly, which can be a steel plate or other supporting member, for placing a test block 70. The guide frame 20 is fixed with the anchor rod drilling machine 80 through a clamping mechanism 22. The clamping mechanism 22 is in sliding fit with a first guide rod 21. When the anchor rod drilling machine 80 drills a hole in the test block 70 upwardly, the clamping mechanism 22 moves along the first guide rod 21, thereby ensuring that the anchor rod drilling machine 80 can drill upwardly normally. A proximity switch 211 is arranged on the first guide rod 21, which can measure the height change of the anchor rod drilling machine 80 before and after drilling, and further calculate the drilling speed.

[0062] The anchor rod drilling machine testing device provided by the present application can perform actual drilling test on the anchor rod drilling machine 80, and detect the drilling capacity of the anchor rod drilling machine 80 in the mine. The displacement driving assembly comprises a first driving mechanism 30 and a second driving mechanism 40, which can drive the guide frame 20 to move in the horizontal plane, and change the drilling position of the test block 70, so as to facilitate multiple tests.

[0063] The test bench 10 is used for fixing various components mounted thereon. The test block 70 is made of rock material. The test block 70 is arranged on the top of the test bench 10, so as to simulate the actual use scene of the anchor rod drilling machine 80.

[0064] Please refer to Figure 1 and Figure 2 . The test bench 10 comprises a support plate 12, fixed columns 13 and a top plate 14. The support plate 12 is arranged horizontally on the ground. The fixed columns 13 are arranged at intervals in the circumferential direction on the support plate 12. The top plate 14 is arranged on the top of the fixed columns 13, and a supporting space is formed above the top plate 14. The support plate 12, the fixed columns 13 and the top plate 14 are all made of steel material, and the structural strength is sufficient to support the rock test block 70 on the top. Specifically, four fixed columns 13 can be arranged.

[0065] The guide frame 20 is arranged on the test bench 10, and the guide frame 20 is used for mounting the anchor rod drilling machine 80. The anchor rod drilling machine 80 is a pneumatic anchor rod drilling machine 80 in the prior art. When mounting, the anchor rod drilling machine 80 is clamped and fixed through the clamping mechanism 22, so that the working end of the anchor rod drilling machine 80 faces upwardly, and a drill rod is mounted on the working end. After the anchor rod drilling machine 80 is connected with a gas source and a water source, the test can be started.

[0066] When the drilling capacity of the anchor rod drilling machine 80 is tested, the anchor rod drilling machine 80 drives the drill rod to move upwardly to drill a hole in the test block 70 on the top. The movement stroke of the anchor rod drilling machine 80 is measured through the proximity switch 211, and the drilling speed can be calculated.

[0067] The clamping mechanism 22 is used to clamp the anchor rod drilling machine 80, which can be a mechanical clamp or the like in the prior art, and can be manually clamped or electrically or pneumatically driven to clamp.

[0068] The proximity switch 211 is a distance detection element commonly used in the prior art, and its specific specifications are not limited. One or more proximity switches 211 can be provided as needed.

[0069] The displacement driving assembly includes a first driving mechanism 30 and a second driving mechanism 40. The first driving mechanism 30 is used to drive the second driving mechanism 40 to move reciprocally along a first horizontal direction. The second driving mechanism 40 is used to drive the guide frame 20 to move reciprocally along a second horizontal direction. After drilling a hole at a position of the test block 70, the horizontal position of the anchor rod drilling machine 80 can be changed by the first driving mechanism 30 and the second driving mechanism 40, so as to facilitate the next test.

[0070] The first driving mechanism 30 and the second driving mechanism 40 can be hydraulic telescopic rods, electric telescopic rods, or motor-driven gear and rack mechanisms, which can realize linear reciprocating movement.

[0071] Please refer to Figure 1 and Figure 2 The top of the test bench 10 is provided with limiting supports 11. The limiting supports 11 are arranged opposite to each other above the supporting assembly. The space above the supporting assembly and between the two limiting supports 11 forms a supporting space, which is used to limit and fix the test block 70, so as to prevent the test block 70 from shaking during the test.

[0072] Please refer to Figure 4 The first driving mechanism 30 includes a first lead screw 31, a first driving member 32, and a second guide rod 33. The first lead screw 31 is arranged along the first horizontal direction on the test bench 10, and the second driving mechanism 40 is threadedly connected with the first lead screw 31. The first driving member 32 is arranged on the test bench 10 and is used to drive the first lead screw 31 to rotate around the central axis thereof. The second guide rod 33 is parallel to the first lead screw 31 and is arranged on the test bench 10. The second driving mechanism 40 is slidingly connected with the second guide rod 33.

[0073] In order to improve the stability of the structure, as shown in Figure 4 , the first lead screw 31 and the second guide rod 33 are provided in two, respectively. The first lead screw 31 and the second guide rod 33 are arranged on the hoop 34, and the hoop 34 is fixedly connected with the fixed column 13. One of the first lead screws 31 is driven to rotate by the first driving member 32, and is drivingly connected with the other first lead screw 31 through a transmission mechanism. The transmission mechanism can be a common transmission form such as a sprocket and a transmission chain 35, a belt pulley and a belt, and the like.

[0074] The first driving member 32 and the second driving member 43 below can be motors, and output shafts of the motors can be connected with the first screw rod 31 through transmission structures such as reducers and shaft couplings.

[0075] Please refer to Figure 5 The second driving mechanism 40 includes a first sliding base 41, a second screw rod 42, a second driving member 43 and a third guide rod 44. The first sliding base 41 is threadedly connected with the first screw rod 31 and is slidingly connected with the second guide rod 33; the second screw rod 42 is arranged on the first sliding base 41 along a second horizontal direction, and the guide frame 20 is threadedly connected with the second screw rod 42; the second driving member 43 is arranged on the first sliding base 41 and is configured to drive the second screw rod 42 to rotate around a central axis of the second screw rod 42; and the third guide rod 44 is parallel to the second screw rod 42 and is arranged on the first sliding base 41, and the guide frame 20 is slidingly connected with the third guide rod 44.

[0076] The second screw rod 42 and the third guide rod 44 are arranged on the first sliding base 41 respectively and are both two in number. The second screw rod 42 and the third guide rod 44 can move together with the first sliding base 41.

[0077] Please refer to Figure 6 The guide frame 20 further includes a second sliding base 23, which is threadedly connected with the second screw rod 42 and is slidingly connected with the third guide rod 44, and the top of the first guide rod 21 is connected with the second sliding base 23.

[0078] In order to prevent the anchor rod drill 80 from being directly contacted with the ground or the support plate 12 during testing and thus being scratched, please refer to Figure 6 The anchor rod drill testing device further includes a support assembly 50, which includes a bottom plate 51, a support rod 52 and an elastic member 53. The bottom plate 51 is arranged at the bottom of the first guide rod 21 and has an avoiding hole penetrating through a thickness of the bottom plate 51; the support rod 52 is slidingly connected with the avoiding hole, and an upper end of the support rod 52 is located above the bottom plate 51 and is provided with a base 521, and a lower end of the support rod 52 is located below the bottom plate 51 and is provided with a pad 522; and the elastic member 53 is arranged between an upper surface of the bottom plate 51 and the base 521 and is configured to support the base 521 upward. When the anchor rod drill 80 is clamped at the clamping mechanism 22 and is in a static state, the lower end of the anchor rod drill 80 is abutted against the base 521, and the elastic member 53 supports the base 521 so that the pad 522 is separated from the bottom of the testing rack 10; when the anchor rod drill 80 is drilling, under the reaction force of drilling, the anchor rod drill 80 compresses the elastic member 53 through the base 521 so that the pad 522 is abutted against the bottom of the testing rack 10.

[0079] The support assembly 50 is located at the bottom of the anchor rod drill 80 and serves to support. The elastic member 53 is a coil spring in particular. Under the elastic force of the elastic member 53, the base 521 serves to support the lower end of the anchor rod drill 80 and can tightly push up the bottom of the anchor rod drill 80 when the anchor rod drill 80 is tested. The bottom plate 51 is fixedly installed at the bottom of the first guide rod 21. The upper end of the support rod 52 is provided with the base 521 which serves to support the bottom of the anchor rod drill 80. The lower end of the support rod 52 is provided with the pad 522. The base 521 and the pad 522 can be made of rubber, nylon or the like and can absorb the impact force when the anchor rod drill 80 is running, thereby preventing the bottom of the anchor rod drill 80 from being scratched.

[0080] Please refer to Figure 7 The clamping mechanism 22 comprises a first clamping seat 221, a second clamping seat 222 and a locking member 223. The first clamping seat 221 is in sliding fit with the first guide rod 21 and has a first clamping groove for accommodating the anchor rod drill 80. The second clamping seat 222 is movably connected with the first clamping seat 221 and has a second clamping groove for accommodating the anchor rod drill 80. The first clamping groove and the second clamping groove jointly form a clamping space for clamping the anchor rod drill 80. The locking member 223 is detachably connected between the first clamping seat 221 and the second clamping seat 222.

[0081] The locking member 223 can be a limiting pin, a latch, a connecting bolt or the like fastener. Before the anchor rod drill 80 is installed, the first clamping seat 221 and the second clamping seat 222 are in a separated state so as to facilitate the installation of the anchor rod drill 80. After the anchor rod drill 80 is installed in place, the first clamping seat 221 and the second clamping seat 222 are connected and fixed by the locking member 223, thereby stably clamping the anchor rod drill 80.

[0082] The first clamping seat 221 and the second clamping seat 222 are movably connected and can be in a separated form or in a structure form of hinged connection through a pivot.

[0083] Please refer to Figure 8 and Figure 9 The first clamping seat 221 and the second clamping seat 222 are respectively provided with a slip bowl 224. The two slip bowls 224 are respectively used to form the first clamping groove and the second clamping groove. The first clamping seat 221 and the second clamping seat 222 are respectively provided with an adjusting groove 2211 along the opening direction of the first clamping groove and the second clamping groove. The slip bowl 224 is in sliding fit in the corresponding adjusting groove 2211. One or both of the first clamping seat 221 and the second clamping seat 222 are further provided with an adjusting hole along the opening direction of the adjusting groove 2211. The clamping mechanism 22 further comprises a jacking bolt 225 which is in screw fit with the adjusting hole. The screw end of the jacking bolt 225 abuts against the corresponding slip bowl 224. The jacking bolt 225 can push the slip bowl 224 to abut against the outer wall of the anchor rod drill 80 by being rotated, thereby achieving clamping.

[0084] The clamping shoe 224 is detachably arranged, and different shapes of the clamping shoe 224 can be replaced to adapt to different shapes of the anchor rod drill 80. The side surface of the clamping shoe 224 used to fit the outer wall of the anchor rod drill 80 can be provided with a flexible protective layer made of rubber, felt or the like to avoid damage to the appearance of the product due to excessive clamping force.

[0085] In order to eliminate the active gap, at least one of the first clamping seat 221 and the second clamping seat 222 is provided with an adjusting hole, and the jacking bolt 225 is arranged in the adjusting hole. The corresponding clamping shoe 224 can be pushed through the adjusting hole to make the clamping shoe 224 abut against the outer wall of the anchor rod drill 80.

[0086] Since the anchor rod drill 80 will be connected to a water source when drilling and testing, water will flow downward along the drill rod. Please refer to Figure 6 and Figure 9 The anchor rod drill testing device further comprises a water receiving box 60, which is arranged on the guide frame 20. The water receiving box 60 has a water receiving groove, the top of which is open. The bottom of the water receiving groove is provided with a mounting hole 61 for the drill rod to pass through and a drainage hole 62. The drainage hole 62 is provided with a drainage connector, and the drainage connector is connected with a drainage pipe. The water receiving groove is used to receive the flowing water and discharge it to other positions through the drainage hole 62 and the drainage pipe.

[0087] Since the anchor rod drill 80 will inevitably cause water or stone splashing when drilling and testing, in order to prevent the splashing water or stone from affecting the transmission parts such as the first lead screw 31 and the second lead screw 42 and the electrical equipment, a protective sleeve or cover can be arranged outside.

[0088] For example, a protective sleeve can be arranged outside the first lead screw 31 and the second lead screw 42. The protective sleeve is a flexible and compressible corrugated protective pipe, which does not affect the normal operation of the first lead screw 31 and the second lead screw 42, and can also play a waterproof and dustproof role.

[0089] It can be understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments, and the specific contents of each combined embodiment will not be described here. After the description, it can be considered that the present application has described each combined embodiment, and different combined embodiments can be supported.

[0090] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
