It also describes the technical problem that "currently, during the drilling process, operators roughly position the holes before drilling, which causes deviations in the distribution of the blast holes, resulting in an irregular arrangement of the blast holes and a poor blasting effect in the mine."

[0029] To solve this technical problem, this utility model provides a blast hole positioning device, which is used for blast hole positioning.

[0030] For details, please refer to Figure 1 - Figure 4 The blast hole positioning device specifically includes:

[0031] Support frame 1 includes end frame 4, and there are two end frames 4. The two end frames 4 are arranged in parallel, and the ends of the two end frames 4 are horizontally fixedly connected by crossbar 5. The lower end of each end frame 4 can be detachably provided with a base 6.

[0032] The guide frame 2 is located between two end frames 4. The guide frame 2 includes a crossbeam 7, the ends of which are slidably connected to the two end frames 4 respectively, and a positioning frame 8 is fixedly connected to the middle of the crossbeam 7.

[0033] The limiting frame 3 is located between the two end frames 4. The limiting frame 3 includes two movable plates 9, which are arranged parallel to the end frames 4. The ends of the two movable plates 9 are vertically slidably connected to the crossbar 5 and are fixedly connected by the connecting rod 11.

Moreover, it can be quickly drilled by two people working together, avoiding the need to fix the device to the drilling surface, thereby effectively improving the drilling efficiency.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figure 1 - Figure 4 A blast hole positioning device, comprising:

[0038] Support frame 1 includes end frame 4, and there are two end frames 4. The two end frames 4 are arranged in parallel, and the ends of the two end frames 4 are horizontally fixedly connected by crossbar 5. The lower end of each end frame 4 can be detachably provided with a base 6.

[0039] The guide frame 2 is located between two end frames 4. The guide frame 2 includes a crossbeam 7, the ends of which are slidably connected to the two end frames 4 respectively, and a positioning frame 8 is fixedly connected to the middle of the crossbeam 7. In order to reduce the weight of the crossbeam 7 and improve its aesthetics, a hollow groove is provided on the crossbeam 7.

[0040] The limiting frame 3 is located between the two end frames 4. The limiting frame 3 includes two movable plates 9, which are arranged parallel to the end frames 4. The ends of the two movable plates 9 are vertically slidably connected to the crossbar 5 and are fixedly connected by the connecting rod 11.

[0041] The connecting rod 11 is inserted into the end of the movable plate 9, and the connecting rod 11 and the movable plate 9 are fixedly connected by screws; in order to increase the friction between the movable plate 9 and the crossbeam 7, the upper end of the movable plate 9 is fixedly connected with an anti-slip pad 10.

[0042] It can be seen that the positioning frame 8 is used to position the hole, the crossbeam 7 is used to support the positioning frame 8, and the position of the positioning frame 8 can be adjusted by sliding the end of the crossbeam 7 to the end frame 4. When using it, hold the two crossbars 5 with both hands, put the bottom of the end frame 4 against the hole position, keep the end frame 4 pressed, slide the crossbeam 7 according to the hole requirements, and adjust the position of the positioning frame 8. Before drilling, hold the connecting rod 11 and move it towards the crossbar 5 so that the movable plate 9 is in contact with the bottom of the crossbeam 7, thereby realizing the movement limit of the crossbeam 7. After the crossbeam 7 is limited, another person holds the drilling tool and works with the positioning frame 8 to perform the drilling operation.

[0043] Example 2:

[0044] The blast hole positioning device provided in Example 1 is further optimized, specifically, as follows: Figure 5 As shown, the base 6 includes a connecting seat 12 and an anti-slip block 13. The upper end of the connecting seat 12 is threadedly connected to the end frame 4, and the lower end of the connecting seat 12 is plugged into the anti-slip block 13. In order to improve the anti-slip performance, wear resistance and service life of the anti-slip block 13, the anti-slip block 13 is made of rubber.

[0045] Through the above structural design, the connecting seat 12 and the end frame 4 are connected by a thread, so that the connecting seat 12 can be disassembled and replaced. The anti-slip block 13 is connected to the connecting seat 12 by a plug-in connection, so that the anti-slip block 13 is easy to replace.
