Description

Technical Field

[0001] This utility model relates to the field of blasting drilling technology, specifically to an engineering blasting drilling device. Background Technology

[0002] Mining engineering mainly involves the extraction of mineral resources. Before mining operations begin, technicians need to perform targeted blasting. The compression, loosening, and damage caused by the explosion can disrupt the ore medium, making it easier to extract the ore. Before blasting, holes need to be drilled at the blasting location to facilitate the placement of explosives.

[0003] Chinese patent document CN221400353U, published on July 23, 2024, discloses an adjustable pre-drilling device for blasting in mining engineering. The device includes a base plate, a crossbeam fixedly installed on the top of the base plate, a first motor fixedly installed on the top of the crossbeam, a cooler fixedly installed on the bottom of the first motor, a guide fixedly installed on the bottom of the cooler, a drill rod fixedly installed on the bottom of the guide, and a drill bit fixedly installed on the bottom of the drill rod. This utility model provides a stable platform through the base plate, supports the motor and connects the drilling rig through the crossbeam, provides driving force to the drilling system through the first motor, reduces the temperature of the drill bit and removes the generated heat through the cooler, controls the direction and angle of the drill bit through the guide, transmits rotational and drilling forces through the drill rod, and facilitates drilling operations through the drill bit. Although the above-mentioned application has many beneficial effects, it still has the following shortcomings: the drill rod has insufficient flexibility in adjusting the drilling position. When it is necessary to adjust the drill rod to align with a new drilling point, the drill rod cannot be adjusted directly. The entire drilling device must be moved to achieve the drilling point transfer, which is not only cumbersome to operate, but also consumes a lot of manpower and time, resulting in extremely low operational convenience.

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.

[0020] Please see Figure 1-4 The present invention provides the following technical solution:

[0021] The engineering blasting drilling device includes a base 1, with two supports 2 fixedly connected to the top of the base 1. Hydraulic cylinders 3 are fixedly mounted on the top of the supports 2 via square plates. Guide rods 4 are fixedly connected to the top of the base 1 at positions corresponding to the supports 2. A lifting frame 5 is slidably connected between the supports 2. The lifting frame 5 is equipped with a linkage mechanism 6, which includes two sliding grooves 61 and multiple fixing grooves 62. Support blocks 63 are slidably connected inside each sliding groove 61. Two horizontal rods 64 are fixedly connected between the support blocks 63. Multiple positioning grooves 65 are provided on each horizontal rod 64. A mounting plate 66 is slidably connected to each horizontal rod 64. A motor 67 is fixedly mounted on the top of the mounting plate 66. A drill rod 68 is rotatably connected to the bottom of the mounting plate 66. A rotating rod 69 is rotatably connected to the front wall of the mounting plate 66. A rotating handle 70 is fixedly connected to one end of the rotating rod 69. A torsion spring 71 is fixedly connected to the rotating handle 70 at the position corresponding to the rotating rod 69. A connecting rod 72 is fixedly connected to the rotating handle 70 at the position corresponding to the torsion spring 71. A pressure-bearing rod 73 is rotatably connected to the front wall of the mounting plate 66 at the position corresponding to the rotating rod 69. A positioning rod 74 is fixedly connected to the pressure-bearing rod 73 at the position corresponding to the positioning groove 65. A vertical rod 75 is fixedly connected to the top of each support block 63. A fixing frame 76 is slidably connected to the vertical rod 75. A spring 77 is fixedly connected to the top of the fixing frame 76 at the position corresponding to the vertical rod 75.

[0022] The top ends of the guide rods 4 are fixedly connected to the bottom ends of the top walls of the corresponding brackets 2. One end of each guide rod 4 slides through the lifting frame 5. The output end of the hydraulic cylinder 3 is fixedly connected to the top end of the lifting frame 5. The guide rods 4 facilitate the movement of the lifting frame 5, while the hydraulic cylinder 3 facilitates the up-and-down movement of the lifting frame 5. Slide grooves 61 are symmetrically opened on the lifting frame 5, and fixing grooves 62 are all opened on the top wall of the lifting frame 5. The fixing frame 76 is C-shaped. The two rods on both sides of the bottom end of the fixing frame 76 are slidably inserted into the corresponding fixing grooves 62. The fixing grooves 62 and the fixing frame 76... The connection facilitates the fixing of the mounting plate 66. The bottom end of the output end of the motor 67 is fixedly connected to the top end of the drill rod 68, and the motor 67 can easily drive the drill rod 68 to rotate. The positioning rod 74 is movably connected inside the corresponding positioning groove 65. The connection between the positioning rod 74 and the positioning groove 65 facilitates the fixing of the mounting plate 66. One end of the torsion spring 71 is fixedly connected to the front wall of the mounting plate 66. One end of the connecting rod 72 slides through the pressure rod 73, and the connecting rod 72 can easily drive the pressure rod 73 to rotate. The top ends of the springs 77 are all fixedly connected to the bottom end of the top wall of the corresponding vertical rod 75.

[0023] In use, the base 1 can be moved to the designated drilling point, and then the handle 70 can be rotated directly. Rotating the handle 70 will cause the rotating rod 69 to rotate, and the rotation of the handle 70 will also cause the torsion spring 71 to twist. Simultaneously, the handle 70 will also cause the connecting rod 72 to rotate. As the connecting rod 72 rotates downwards with the handle 70, it will compress the pressure rod 73. At this time, the pressure rod 73 will also rotate under pressure. The part connecting the pressure rod 73 and the connecting rod 72 will rotate downwards, causing the other end of the pressure rod 73 to rotate upwards. The upward-rotating end of the pressure rod 73 will... The positioning rod 74 rotates upward, causing it to separate from the connected positioning groove 65. Simultaneously, the upward rotation of the positioning rod 74 presses against the bottom of the top wall of the fixing frame 76, causing the fixing frame 76 to move upward under pressure. The upward movement of the fixing frame 76 is guided by the two vertical rods 75. The upward movement of the fixing frame 76 also compresses and contracts the spring 77, causing the fixing frame 76 to separate from the connected fixing groove 62. At this point, the positioning rod 74 separates from the positioning groove 65, and the fixing frame 76 separates from the fixing groove 62, allowing for direct... By rotating handle 70, force is applied to mounting plate 66, causing it to slide on the two transverse rods 64 to a designated position. Alternatively, rotating handle 70 and mounting plate 66 can directly pull the two transverse rods 64 back and forth. The forward movement of the transverse rods 64 will jointly drive the support block 63 to move forward in the slide groove 61. After the movement is completed, positioning rod 74 corresponds to the remaining positioning grooves 65, and fixing bracket 76 also corresponds to the remaining fixing grooves 62. At this time, releasing handle 70 will cause torsion spring 71 to drive handle 70 to reset, and the resetting handle 70 will also cause positioning rod 74 to move downward. Rotate to reset, and the positioning rod 74 will connect to the corresponding positioning groove 65. The fixing frame 76 will also move down under the action of the two springs 77. Then the fixing frame 76 connects to the corresponding fixing groove 62. The drilling point can be switched without moving the entire device, which significantly reduces the intensity of operation and the effort required. At this time, the mounting plate 66 is fixed in position, and the motor 67 and hydraulic cylinder 3 can be started. The rotation of the motor 67 will drive the drill rod 68 to rotate, and the output end of the hydraulic cylinder 3 will extend and drive the lifting frame 5 to move down. The movement of the lifting frame 5 will cause the rotating drill rod 68 to perform drilling work.
