Description

Technical Field

[0001] This utility model belongs to the field of mining engineering technology, specifically relating to a blasting device for rock excavation steps. Background Technology

[0002] Blasting equipment plays a crucial role in rock excavation projects. Various types of equipment work together to ensure the smooth progress of blasting operations. These include rock drills, down-the-hole drills, and rotary drills. Their main function is to drill blast holes in the rock that meet design requirements, preparing for subsequent charging and blasting. Different types of drilling equipment are suitable for drilling operations in rocks of varying hardness and scale. For example, rock drills are often used for small-scale projects or shallow-hole blasting; down-the-hole drills and rotary drills are suitable for medium- and deep-hole blasting, capable of drilling larger diameter and deeper blast holes in hard rock to meet the needs of large-scale rock excavation.

[0003] Some existing drilling rigs often have the drawback of difficulty in adjusting the angle during the drilling process. For projects with high engineering precision requirements, such as tunnel excavation and slope protection, deviations in the borehole angle may affect the quality of the entire project, leading to irregular tunnel outlines and serious over-excavation or under-excavation. This not only increases the difficulty and cost of subsequent support and lining, but may also affect the stability and safety of the tunnel. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-4 This embodiment of the present invention provides a blasting device for excavating stone steps, comprising:

[0028] The drilling mechanism 100 includes a support platform 101, a support plate 102 fixedly connected to the outer surface of the support platform 101, a drive assembly 103 disposed on the outer surface of the support platform 101 for drilling boreholes, and a flipping assembly 104 disposed directly below the support platform 101 for controlling the drilling angle of the drive assembly 103.

[0029] It should be noted that the support platform 101 is used to provide an installation surface for the drive assembly 103 to ensure stability during drilling operations, and the support plate 102 is used to assist in supporting and positioning some parts of the drive assembly 103.

[0030] Specifically, the drive assembly 103 includes a first motor 103a adapted to be installed on the outer surface of the support plate 102, a threaded rod 103b fixedly connected to the output end of the first motor 103a via a coupling, an internal threaded block 103c threadedly connected to the outer surface of the threaded rod 103b, a connecting plate 103d fixedly sleeved on the outer surface of the internal threaded block 103c, and a limiting rod 103e fixedly connected to the outer surface of the support platform 101 and used in conjunction with the connecting plate 103d.

[0031] Furthermore, the outer end face of the threaded rod 103b is fixedly mounted on the outer surface of the support platform 101 by a bearing, and the inner surface of the connecting plate 103d slides in contact with the outer surface of the limiting rod 103e.

[0032] Preferably, the drive assembly 103 also includes a second motor 103f adapted to be installed on the outer surface of the limit rod 103e, a spiral drill rod 103g fixedly connected to the output end of the second motor 103f via a coupling, and a circular hole 103h opened on the outer surface of the support platform 101 and used in conjunction with the spiral drill rod 103g.

[0033] It should be noted that the output end of the second motor 103f extends through to the side of the connecting plate 103d near the circular hole 103h, and a rotating bearing sleeve is installed at the connection between the output end of the second motor 103f and the connecting plate 103d.

[0034] It should be noted that after the first motor 103a is energized, it generates rotational power, which drives the threaded rod 103b to rotate. The threaded rod 103b uses the principle of thread transmission to drive the internal thread block 103c to drive the connecting plate 103d to move axially along its surface. Then, the connecting plate 103d drives the second motor 103f and the auger drill rod 103g to move synchronously, thereby adjusting the drilling depth. The limiting rod 103e is used to limit and guide the movement of the connecting plate 103d to ensure that the auger drill rod 103g moves smoothly in a straight line. The second motor 103f is used to provide rotational power for the auger drill rod 103g. Driven by the second motor 103f, the auger drill rod 103g rotates at high speed and drills into the rock to perform blast hole drilling operations. The circular hole 103h is used to provide a passage for the auger drill rod 103g to pass through during the drilling process.

[0035] Furthermore, the flipping assembly 104 includes a base 104a disposed directly below the support platform 101, a third motor 104b adapted to be installed at the center of the outer surface of the base 104a, a support column 104c fixedly connected to the output end of the third motor 104b via a coupling, a fixing sleeve 104d fixedly connected to the outer end face of the support column 104c, and a rotating rod 104e rotatably connected to the inner surface of the fixing sleeve 104d.

[0036] Specifically, the flipping assembly 104 also includes a connecting block 104f fixedly connected to the outer end face of the rotating rod 104e and used in conjunction with the support platform 101, a cylinder 104g adapted to be installed on the outer surface of the base 104a, a circular guide rail 104h fixedly installed on the output end of the cylinder 104g, and a ball bearing 104i disposed in the inner cavity of the circular guide rail 104h.

[0037] It should also be noted that the base 104a is used as the bottom support structure for the entire blasting equipment, placing it stably on the working ground. After the third motor 104b is powered on, it can drive the support column 104c to rotate. Then, the support column 104c drives the rotating rod 104e and the connecting block 104f to rotate synchronously through the fixed sleeve 104d, thereby driving the support platform 101 to rotate horizontally.

[0038] Furthermore, the bottom of the support platform 101 is fixedly connected to the top of the connecting block 104f, and the outer surface of the ball bearing 104i slides in contact with the inner surface of the circular guide rail 104h.

[0039] It should be explained that the cylinder 104g pushes the circular guide rail 104h to move through its telescopic movement. The circular guide rail 104h moves under the push of the cylinder 104g, which in turn pushes the ball bearing 104i to roll. The ball bearing 104i then drives the swing block 104j to move, thereby causing the swing block 104j to drive the rotating rod 104e to rotate, thus adjusting the angle of the support platform 101. The telescopic rod 104k plays a role in preventing the circular guide rail 104h from shifting position during the process of the cylinder 104g pushing the circular guide rail 104h, so as to ensure the accuracy and stability of the angle adjustment. The connecting rod 104l is used to connect the telescopic rod 104k and the output end of the cylinder 104g to transmit the force.

[0040] Preferably, the flipping assembly 104 further includes a swing block 104j fixedly connected to the outer surface of the ball 104i and used in conjunction with the rotating rod 104e, a telescopic rod 104k fixedly installed on the outer surface of the base 104a and used in conjunction with the cylinder 104g, and a connecting rod 104l fixedly sleeved on the outer surface of the telescopic segment of the telescopic rod 104k.

[0041] It should be noted that the inner surface of the end of the connecting rod 104l away from the telescopic rod 104k is fixedly connected to the outer surface of the output end of the cylinder 104g. The telescopic rod 104k is used to prevent the position of the circular guide rail 104h from shifting.

[0042] In use, first, the base 104a is firmly placed on the working ground. Then, according to the designed position of the blast hole, the first motor 103a is started. The rotational power generated by the first motor drives the threaded rod 103b to rotate. The threaded transmission causes the internal threaded block 103c to move the connecting plate 103d along the axial direction of the threaded rod. At the same time, the limiting rod 103e limits and guides the connecting plate 103d to ensure its smooth linear movement. This, in turn, drives the second motor 103f and the auger drill rod 103g to a suitable horizontal position. Next, the second motor 103f is started to provide rotational power to the auger drill rod 103g, causing it to rotate at high speed and drill into the rock, drilling the blast hole through the circular hole 103h. During the drilling process, if it is necessary to adjust the drilling depth, the first motor 103a can be started again, and the above transmission process can be repeated for adjustment.

[0043] When the drilling angle needs to be adjusted: the third motor 104b is started, driving the support column 104c to rotate, which in turn drives the fixed sleeve 104d, the rotating rod 104e, the connecting block 104f, and the support platform 101 to rotate horizontally, achieving a preliminary adjustment of the angle. Then, the cylinder 104g is started, and its telescopic movement pushes the circular guide rail 104h to move. The ball bearings 104i inside the circular guide rail 104h roll, driving the swing block 104j to move, causing the rotating rod 104e to rotate, thereby precisely adjusting the angle of the support platform 101.

[0044] During this process: the telescopic rod 104k moves synchronously under the connection of the connecting rod 104l to prevent the circular guide rail 104h from shifting position and to ensure the accuracy and stability of angle adjustment.

[0045] In summary, through the cooperation of the drive component 103 and the tilting component 104, the drilling angle and direction of the auger rod 103g can be flexibly adjusted during the rock excavation bench blasting operation, so that the blast holes are arranged according to actual needs, ensuring that the explosives are more rationally distributed in the rock, avoiding over-excavation or under-excavation, so as to provide a good foundation for subsequent engineering construction and ensure the quality of the project.
