The second drive mechanism 40 is used to drive the guide frame 20 to move in a second horizontal direction, which is perpendicular to the first horizontal direction.

[0060] Compared with the prior art, the beneficial effects of the anchor drilling rig testing device provided in this application embodiment are:

[0061] An anchor bolt drilling rig testing device provided in this application includes a test bench 10, a guide frame 20, and a displacement drive assembly. The top of the test bench 10 has a support assembly, which can be a support component such as a steel plate, for placing a test block 70. The guide frame 20 fixes the anchor bolt drilling rig 80 through a clamping mechanism 22. The clamping mechanism 22 is slidably engaged with a first guide rod 21. When the anchor bolt drilling rig 80 drills upwards into the test block 70, the clamping mechanism 22 moves along the first guide rod 21 to ensure that the anchor bolt drilling rig 80 can drill upwards normally. A proximity switch 211 is provided on the first guide rod 21, which can measure the height change of the anchor bolt drilling rig 80 before and after drilling, and then calculate the drilling speed.

[0062] The anchor bolt drilling rig testing device provided in this application can perform actual drilling tests on the anchor bolt drilling rig 80 to detect its drilling capability in mines. The displacement drive assembly includes a first drive mechanism 30 and a second drive mechanism 40, which can drive the guide frame 20 to move in the horizontal plane, changing the drilling position of the test block 70 to facilitate multiple tests.

[0063] The test bench 10 is used to fix the various components installed on it. The test block 70 is made of rock. The test block 70 is placed on the top of the test bench 10 to simulate the real use scenario of the anchor drilling rig 80.

[0064] Please see Figure 1 and Figure 2 The test bench 10 includes a support plate 12, fixed columns 13, and a top plate 14. The support plate 12 is laid flat on the ground; multiple fixed columns 13 are spaced circumferentially on the support plate 12; the top plate 14 is located on top of the fixed columns 13, forming a support space above the top plate 14. The support plate 12, fixed columns 13, and top plate 14 are all made of steel, with sufficient structural strength to support the rock specimen 70 on top. Four fixed columns 13 can be specifically installed.

[0065] A guide frame 20 is mounted on the test bench 10 and is used to install the anchor bolt drill 80. The anchor bolt drill 80 is a pneumatic anchor bolt drill 80 of the prior art. During installation, the anchor bolt drill 80 is clamped and fixed by the clamping mechanism 22, so that the working end of the anchor bolt drill 80 faces upward, and a drill rod is installed at the working end. After connecting the anchor bolt drill 80 to the air and water supply, the test can be started.

[0066] When testing the drilling capability of the anchor drilling machine 80, the anchor drilling machine 80 drives the drill rod to move upward to drill a hole in the test block 70 at the top. The movement stroke of the anchor drilling machine 80 is measured by the proximity switch 211, and the drilling speed can then be calculated.

[0067] The clamping mechanism 22 is used to clamp and fix the anchor drilling rig 80. The clamping mechanism 22 can be a mechanical gripper or other clamp in the prior art. It can be manually clamped or electrically or pneumatically driven to achieve clamping.

[0068] The proximity switch 211 is a common distance detection element in the prior art. There are no restrictions on its specific specifications and models. One or more proximity switches 211 can be set as needed.

[0069] The displacement drive assembly includes a first drive mechanism 30 and a second drive mechanism 40. The first drive mechanism 30 drives the second drive mechanism 40 to reciprocate along a first horizontal direction, and the second drive mechanism 40 drives the guide frame 20 to reciprocate along a second horizontal direction. After drilling a hole at one position on the test block 70, the horizontal position of the anchor drilling rig 80 can be changed by the first drive mechanism 30 and the second drive mechanism 40 to facilitate the next test.

[0070] The first drive mechanism 30 and the second drive mechanism 40 can be hydraulic telescopic rods, electric telescopic rods, or gear and rack mechanisms driven by motors, as long as they can achieve linear reciprocating movement.

[0071] Please see Figure 1 and Figure 2 The test bench 10 is provided with two limiting brackets 11 on its top. The two limiting brackets 11 are positioned opposite each other above the support component. The support space is formed above the support component and between the two limiting brackets 11, which is used to limit and fix the test block 70 to prevent the test block 70 from shaking during the test.

[0072] Please see 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 disposed on the test bench 10 along a first horizontal direction, and the second driving mechanism 40 is threadedly engaged with the first lead screw 31. The first driving member 32 is disposed on the test bench 10 and is used to drive the first lead screw 31 to rotate around its own central axis. The second guide rod 33 is parallel to the first lead screw 31 and disposed on the test bench 10, and the second driving mechanism 40 is slidably engaged with the second guide rod 33.

[0073] To improve structural stability, such as Figure 4 As shown, two first lead screws 31 and two guide rods 33 are respectively provided. The first lead screws 31 and the second guide rods 33 are respectively mounted on clamps 34, which are fixedly connected to the fixed column 13. One of the first lead screws 31 is driven to rotate by a first driving member 32 and is connected to the other first lead screw 31 through a transmission mechanism. The transmission mechanism can be a common transmission form such as a sprocket and transmission chain 35, a pulley and a belt.

[0074] The first driving component 32 and the second driving component 43 mentioned below can be motors, and the output shaft of the motor can be connected to the first lead screw 31 through a transmission structure such as a reducer or coupling.

[0075] Please see Figure 5 The second drive mechanism 40 includes a first slide block 41, a second lead screw 42, a second drive member 43, and a third guide rod 44. The first slide block 41 is threadedly engaged with the first lead screw 31 and slidably engaged with the second guide rod 33. The second lead screw 42 is disposed on the first slide block 41 along a second horizontal direction, and the guide frame 20 is threadedly engaged with the second lead screw 42. The second drive member 43 is disposed on the first slide block 41 and is used to drive the second lead screw 42 to rotate around its own central axis. The third guide rod 44 is parallel to the second lead screw 42 and disposed on the first slide block 41, and the guide frame 20 is slidably engaged with the third guide rod 44.

[0076] The second lead screw 42 and the third guide rod 44 are respectively mounted on the first slide 41, and there are two of each. The second lead screw 42 and the third guide rod 44 can move together with the first slide 41.

[0077] Please see Figure 6 The guide frame 20 also includes a second slide block 23, which is threadedly engaged with the second lead screw 42 and slidably engaged with the third guide rod 44. The top of the first guide rod 21 is connected to the second slide block 23.

[0078] To prevent the anchor drilling rig 80 from directly contacting the ground or support plate 12 during testing, causing damage and paint chipping, please refer to [link to relevant documentation]. Figure 6 An anchor drilling rig testing device further includes a support assembly 50, which includes a base plate 51, a support rod 52, and an elastic element 53. The base plate 51 is located at the bottom of the first guide rod 21 and has a clearance hole extending through its own thickness. The support rod 52 is slidably fitted into the clearance hole. The upper end of the support rod 52 is located above the base plate 51 and has a base 521. The lower end of the support rod 52 is located below the base plate 51 and has a pad 522. The elastic element 53 is located between the upper surface of the base plate 51 and the base 521 and is configured to support the base 521 upwards. When the anchor drill 80 is clamped in the clamping mechanism 22 and is in a static state, the lower end of the anchor drill 80 abuts against the base 521, and the elastic element 53 supports the base 521 so that the pad 522 is separated from the bottom of the test bench 10. When the anchor drill 80 drills, under the reaction force of the drilling, the anchor drill 80 compresses the elastic element 53 through the base 521 so that the pad 522 abuts against the bottom of the test bench 10.

[0079] The support assembly 50 is located at the bottom of the anchor drilling rig 80 and serves a supporting function. The elastic element 53 is specifically a helical spring. Under the elastic force of the elastic element 53, the base 521 supports the lower end of the anchor drilling rig 80 and can push upwards to the bottom of the anchor drilling rig 80 during testing. The base 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 supports the bottom of the anchor drilling rig 80. The lower end of the support rod 52 is provided with a pad 522. The base 521 and the pad 522 can be made of materials such as rubber and nylon, which can absorb the impact force of the anchor drilling rig 80 during operation and prevent the bottom of the anchor drilling rig 80 from having bump marks.

[0080] Please see Figure 7 The clamping mechanism 22 includes a first clamping seat 221, a second clamping seat 222, and a locking member 223. The first clamping seat 221 is slidably engaged with the first guide rod 21 and has a first groove for accommodating the anchor drilling rig 80; the second clamping seat 222 is movably connected to the first clamping seat 221 and has a second groove for accommodating the anchor drilling rig 80. The first groove and the second groove together form a clamping space for clamping the anchor drilling rig 80; the locking member 223 is detachably connected between the first clamping seat 221 and the second clamping seat 222.

[0081] The locking component 223 can be a limit pin, a latch, a connecting bolt, or other fasteners. Before installing the anchor drilling rig 80, the first clamping seat 221 and the second clamping seat 222 are in a separated state to facilitate the insertion of the anchor drilling rig 80. After the anchor drilling rig 80 is installed in place, the locking component 223 connects and fixes the first clamping seat 221 and the second clamping seat 222 to securely clamp the anchor drilling rig 80.

[0082] The first card holder 221 and the second card holder 222 are movably connected. They can be separate from each other or they can be connected by a hinge at one end of a rotating shaft.

[0083] Please see Figure 8 and Figure 9 The first clamping seat 221 and the second clamping seat 222 are respectively provided with clamping slips 224, which are used to form the first clamping groove and the second clamping groove, respectively. The first clamping seat 221 and the second clamping seat 222 are respectively provided with adjustment grooves 2211 along the opening direction of the first clamping groove and the second clamping seat 222 along the opening direction of the second clamping groove, respectively. The clamping slips 224 are slidably fitted in the corresponding adjustment grooves 2211. One or both of the first clamping seat 221 and the second clamping seat 222 are also provided with adjustment holes along the opening direction of the adjustment grooves 2211. The clamping mechanism 22 also includes a tightening bolt 225, which is threadedly engaged with the adjustment hole. The screw end of the tightening bolt 225 abuts against the corresponding clamping slip 224. Rotating the tightening bolt 225 can push the clamping slip 224 to abut against the outer wall of the anchor drilling machine 80 to achieve clamping.

[0084] The slip 224 is detachable, and different shapes of slip 224 can be replaced to fit different shapes of anchor drilling rigs 80. The side of the slip 224 that fits against the outer wall of the anchor drilling rig 80 can be equipped with a flexible protective layer of materials such as rubber or felt to prevent damage to the product's appearance due to excessive clamping force.

[0085] To eliminate the gap, at least one of the first locator 221 and the second locator 222 is provided with an adjustment hole, and the tightening bolt 225 is set in the adjustment hole. The corresponding slip 224 can be pushed through the adjustment hole so that the slip 224 is pressed against the outer wall of the anchor drilling machine 80.

[0086] Because the anchor drilling rig 80 connects to a water source during drilling tests, water will flow downwards along the drill rod. Please refer to [link / reference needed]. Figure 6 and Figure 9 An anchor drilling rig testing device also includes a water receiving box 60, which is disposed on a guide frame 20. The water receiving box 60 has a water receiving trough with an opening at the top and a mounting hole 61 and a drain hole 62 at the bottom. The mounting hole 61 is for the drill rod to pass through, and the drain hole 62 is provided with a drain connector connected to a drain pipe. The water receiving trough is used to collect the flowing water and discharge it to other locations through the drain hole 62 and the drain pipe.

[0087] Since water or gravel will inevitably splash during the drilling test of the anchor drilling rig 80, protective sleeves or covers can be installed on the outside of the components such as the first lead screw 31 and the second lead screw 42 and electrical equipment to prevent the splashed water or gravel from affecting them.

[0088] For example, protective sleeves can be installed over the first lead screw 31 and the second lead screw 42. The protective sleeves are flexible and compressible corrugated protective tubes, which will not affect the normal operation of the first lead screw 31 and the second lead screw 42, and can also play a role in waterproofing and dustproofing.

[0089] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present invention specification has recorded each combined embodiment and can support different combined embodiments.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
