In mining, precise positioning of the blasting hole can make the ore blocks after blasting uniform in size, which is convenient for subsequent excavation and transportation, while reducing excessive damage to the surrounding rocks.

[0003] In existing technologies, most measuring plates are fixed installation structures, resulting in a large overall size of the equipment. This occupies a lot of space during transportation, increasing transportation costs and difficulties. At the same time, they also require a large storage space and are difficult to stack compactly with other equipment, reducing space utilization.

[0004] In response to the technical problem of difficulty in adjusting the size of the equipment, this application proposes a blast hole positioning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to adjust the size of the equipment. A blasting hole positioning device is proposed that allows the measuring frame to be rotated backward by pulling the lever, thereby reducing the size of the equipment, effectively lowering transportation difficulty and cost, and improving transportation efficiency. Simultaneously, the smaller size occupies less space during storage, making it easier to store in warehouses, sheds, and other storage locations, improving the utilization rate of storage space, and also facilitating equipment management and maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A blast hole positioning device includes a base, a locking rod slidably connected to the inner wall of the base, a measuring frame connected to the outer wall of the locking rod via a buckle assembly for flipping and folding the measuring frame, a positioning assembly provided on the inner wall of the measuring frame for positioning the blast hole, threaded rods threadedly connected to all four sides of the inner wall of the base, a rotating assembly provided at the bottom end of each threaded rod for adjusting the angle of the base, a spirit level fixedly connected to all four sides of the top of the base, and the outer wall of the measuring frame rotatably connected to the inner wall of the base.

[0008] Furthermore, the buckle assembly includes a slot formed on the right side of the inner wall of the measuring frame, the outer wall of the buckle rod is disposed on the inner wall of the slot, and the shape of the buckle rod matches the slot.

[0009] Furthermore, a limit block is provided on the outer wall of the lever, a spring is fixedly connected to the rear end of the limit block, the other end of the spring is fixedly connected to the inner wall of the base, and the outer wall of the limit block is slidably connected to the inner wall of the base.

[0010] Furthermore, sliders are slidably connected to both sides of the inner wall of the measuring frame, and rotating rods are rotatably connected to the inner walls of the sliders. The other end of each rotating rod is rotatably connected to the inner wall of the base.

[0011] Furthermore, the positioning component includes an electric push rod fixedly connected to the rear end of the measuring frame, a measuring frame fixedly connected to the front end of the electric push rod, and the outer wall of the measuring frame slidably connected to the inner wall of the measuring frame.

[0012] Furthermore, a linear motor is fixedly connected to the inner wall of the measuring frame, and a laser lamp is slidably connected to the outer wall of the linear motor.

[0013] Furthermore, the rotating assembly includes a connecting block rotatably connected to the bottom end of the threaded rod, and a support plate is rotatably connected to the outer wall of the connecting block.

[0014] Furthermore, each of the inner walls of the support plate is rotatably connected to a sliding rod, and the outer walls of the sliding rods are slidably connected to the inner wall of the base.

[0015] This utility model has the following beneficial effects:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 2-4 As shown, one embodiment of this utility model provides a blast hole positioning device, including a base 1, a locking rod 2 slidably connected to the inner wall of the base 1, a measuring frame 5 provided on the outer wall of the locking rod 2, a slot 6 opened on the right side of the inner wall of the measuring frame 5, the outer wall of the locking rod 2 being set on the inner wall of the slot 6, the shape of the locking rod 2 fitting the slot 6, a limiting block 3 provided on the outer wall of the locking rod 2, a spring 4 fixedly connected to the rear end of the limiting block 3, the other end of the spring 4 fixedly connected to the inner wall of the base 1, the outer wall of the limiting block 3 slidably connected to the inner wall of the base 1, sliders 7 slidably connected to both sides of the inner wall of the measuring frame 5, rotating rods 8 rotatably connected to the inner walls of the sliders 7, the other ends of the rotating rods 8 rotatably connected to the inner wall of the base 1 for flipping and folding the measuring frame 5.

[0029] Specifically, the slot 6 is shaped like a 90-degree rotating lever 2 and a non-rotating lever 2, used to limit the measurement frame 5 after it has rotated 90 degrees. Secondly, when the measurement frame 5 rotates, it drives the slider 7 on the inner wall of the measurement frame 5 to slide and drives the rotating rod 8 to rotate, thus supporting the measurement frame 5. Furthermore, when it is necessary to flip the measurement frame 5, it is only necessary to push the limiting block 3 and push the lever 2 to rotate and fold the measurement frame 5 backward, reducing the size of the equipment. By pulling the lever 2, the measurement frame 5 can be rotated backward, reducing the size of the equipment, effectively reducing transportation difficulty and cost, and improving transportation efficiency. At the same time, during storage, the smaller size can occupy less space, making it easier to store in warehouses, sheds and other storage places, improving the utilization rate of storage space, and also facilitating the management and maintenance of the equipment.

[0030] Reference Figure 1 , Figure 5 and Figure 6 As shown, threaded rods 13 are threadedly connected to the four sides of the inner wall of the base 1, and bubble levels 17 are fixedly connected to the four sides of the top of the base 1. The outer wall of the measuring frame 5 is rotatably connected to the inner wall of the base 1. An electric push rod 9 is fixedly connected to the rear end of the measuring frame 5. A measuring frame 10 is fixedly connected to the front end of the electric push rod 9. The outer wall of the measuring frame 10 is slidably connected to the inner wall of the measuring frame 5. A linear motor 11 is fixedly connected to the inner wall of the measuring frame 10. A laser light 12 is slidably connected to the outer wall of the linear motor 11 for positioning the blasting hole. A connecting block 14 is rotatably connected to the bottom end of the threaded rod 13. A support plate 15 is rotatably connected to the outer wall of the connecting block 14. A slide rod 16 is rotatably connected to the inner wall of the support plate 15. The slide rod 16 is slidably connected to the outer wall of the base 1 for adjusting the angle of the base 1.

[0031] Specifically, scales are provided on the outer walls of the measuring frame 5 and the measuring frame 10 to observe the length of movement when adjusting the laser lamp 12. Secondly, the device controls the electric push rod 9 and the linear motor 11 through an external controller. By controlling the electric push rod 9 and the linear motor 11, it is not necessary to manually adjust the position of the blasting hole, which greatly reduces the error caused by human factors and thus more accurately locates the position of the blasting hole. At the same time, by rotating the threaded rods 13 on the four sides, the angle of the support plates 15 on both sides can be adjusted to keep the device in a horizontal state, ensuring the accuracy of measurement and positioning and improving the adaptability and versatility of the device.

[0032] Working principle: First, push the base 1 to adjust the position of the equipment. Second, rotate the threaded rod 13, which drives the bottom connecting block 14, support plate 15, and slide rod 16 downwards. Simultaneously, depending on the ground angle, rotate the threaded rods 13 on all four sides, causing the support plates 15 on both sides to rotate, adjusting the equipment angle. Observe the level bubble 17 to ensure the equipment is level. Next, push the limit block 3 backward to remove it from the locking rod 2, and move the locking rod 2 to the left to remove it from the slot 6. Once the measuring frame 5 reaches its limit, it can be rotated forward to a vertical position. Then, the locking rod 2 is pulled to the right to engage it in the slot 6. The limiting block 3 is secured to the outer wall of the locking rod 2 by the spring 4, thus limiting the locking rod 2 and the measuring frame 5. Next, the electric push rod 9 and the linear motor 11 can be controlled by the controller. The electric push rod 9 drives the measuring frame 10 to slide up and down, and the linear motor 11 drives the laser lamp 12 to slide left and right, thereby adjusting the position of the laser lamp 12. The laser point emitted by the laser lamp 12 is used to locate the blasting point.
