Description

Technical Field

[0001] This utility model belongs to the field of blasting hole drilling equipment, and specifically relates to a blasting hole opening device. Background Technology

[0002] A blasting hole opener is a device used to open blast holes in engineering blasting operations. Current blasting hole openers suffer from drawbacks such as cumbersome movement and difficult drilling transport. The difficulty in movement stems primarily from their typically large size and weight, coupled with a lack of convenient mobility design. To ensure the opener's power and stability, their complex and bulky structure makes transfer between different construction sites difficult. The difficulty in drilling transport arises from the inaccurate and inefficient coordination between the transport and drilling components. This may be due to insufficient stability of the transport component or susceptibility of the drilling component to external interference during transport. Conventional solutions to the movement problem involve using external handling equipment such as cranes, but this increases costs, is limited by site constraints, and impacts construction efficiency. For the drilling transport problem, methods such as optimizing the transport component design to improve its accuracy and stability are commonly employed. However, these optimizations may require significant technical investment and costs, and in actual construction, complex transport structures are more prone to failure, leading to difficult maintenance and delays in construction. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0019] 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.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a blasting hole opening device, comprising: a base assembly and an opening component 200. The opening component 200 is mounted on the upper surface of the base assembly. The base assembly includes: a base box 100, casters 110, a handle 130, a partition 160, a lifting plate 140, an electric push rod 150, and a door 120. The lower surface of the base box 100 is equipped with casters 110 with a self-locking structure. The upper surface of the base box 100 is equipped with the lifting plate 140 via the electric push rod 150. The interior of the base box 100 is equipped with a partition 160. A door 120 is installed on the side surface. The opening assembly 200 includes: a base plate 210-210, a vertical plate 220, a vertical plate 230, a slide bar 250, a conveyor, a slider 260, a base plate 270, a fixing component, and a perforating component. The front and rear surfaces of the base plate are symmetrically equipped with the vertical plate 230 and the vertical plate 220, respectively. The slide bar 250 and the conveyor are installed between the vertical plate 220 and the vertical plate 230. The outer surface of the slide bar 250 and the conveyor is equipped with the base plate 270 via the slider 260. The upper surface of the base plate 270 is equipped with a perforating component via the fixing component.

[0021] Please see Figures 1 to 4 As the first embodiment of this utility model: a universal wheel 110 with a self-locking structure is installed at each of the four corners of the lower surface of the base box 100 by screws; a box door 120 is damped and hinged to the left side surface of the base box 100 by a damping hinge; a partition 160 is installed between the upper inner wall and the lower inner wall inside the base box 100; and two receiving cavities are formed inside the base box 100 by the partition 160.

[0022] The left cavity contains a power supply assembly, and the bottom of the right cavity is evenly equipped with four electric push rods 150. The end of the electric push rod 150 away from the bottom box 100 is connected to the four corners of the lower surface of the lifting plate 140. The lifting plate 140 is movably mounted on the upper surface of the bottom box 100 via the electric push rods 150.

[0023] In use, the user first opens the self-locking casters 110 on the lower surface of the base box 100, then moves the base box 100 using the handle 130 to the desired location for creating a blasting hole. The user then activates the electric push rod 150 inside the base box 100, extending its telescopic rod to raise the opening assembly 200 on the upper surface of the lifting plate 140. After adjusting the height of the opening assembly 200 to the appropriate position for creating the blasting hole (the minimum position for creating the blasting hole must not be lower than the lowest height of the electric push rod 150 after extension and retraction, and the minimum height for creating the blasting hole...), the user proceeds to the next step. The highest position (not exceeding the maximum height of the electric push rod 150 after extension and retraction) allows the user to activate the drilling component 200 to drill holes for blasting. Because the universal wheels 110 with a self-locking structure allow the entire drilling device to move easily between different construction sites, eliminating the need for extensive manual labor and greatly improving the equipment's mobility. Simultaneously, the lifting plate 140 connected to the electric push rod 150 can adjust the height of the drilling component 200 according to different construction needs. When drilling blast holes, the drilling equipment can be adjusted to a suitable height, making it suitable for different equipment.

[0024] Please see Figures 1 to 4 As a second embodiment of the present utility model: a base plate 210210 is installed at the center of the upper surface of the lifting plate 140, a vertical plate 230 with an L-shaped cross-section is installed at the front edge of the upper surface of the base plate 210210, a vertical plate 220 is installed on the rear surface of the base plate 210210, and a sliding rod 250 is symmetrically installed at the two corners of the upper edge between the vertical plate 220 and the vertical plate 230.

[0025] The threaded rod 240 and the motor 241 are mounted on the lower surface of each slide rod 250 via the vertical plate 1 220 and the vertical plate 230. Two motors 241 are symmetrically mounted on the rear surface of the vertical plate 1 220. The output shaft of the motor 241 is rotatably connected to the threaded rod 240. A slider 260 is slidably mounted on the outer surface of each slide rod 250 and the threaded rod 240.

[0026] The device includes a drilling motor 280, a drill rod 290, and a cutting edge 291. A base plate 270 is mounted on the upper surface of two sliders 260. Two fasteners 271 are mounted on the upper surface of the base plate 270. The drilling motor 280 is tightly fitted inside the two fasteners 271. The drill rod 290 is mounted on the output shaft of the drilling motor 280. The cutting edge 291 is integrally formed at the end of the drill rod 290 away from the drilling motor 280.

[0027] In use, when the opening component 200 is moved to the location where a blasting hole needs to be opened through the operation steps of the first embodiment, the user can activate the motor 241 on the rear surface of the vertical plate 230, causing the output shaft of the motor 241 to drive the threaded rod 240 to rotate, thereby causing the slider 260 on the outer surface of the threaded rod 240 to move along the slide rod 250, thereby causing the base plate 270 on the upper surface of the slider 260 to move, and then causing the drilling component on the upper surface of the base plate 270 to move towards the blasting hole to be opened. When moving the drilling component, the user can activate the drilling motor 280, causing the drilling motor 280 to drive the drill rod 290 and the cutting head 291 to rotate, thereby coordinating the above steps with the cutting head 291. The 91 and drill rod 290 are used to open blasting holes. The user can select the conveying length of the conveyor according to the actual situation, and then determine the depth of the blasting hole. (The diameter of the drill rod 290 and the cutting edge 291 can be selected and replaced according to the actual situation. A larger diameter cutting edge 291 and drill rod 290 can open a larger diameter blasting hole. As for the selection of the diameter of the cutting edge 291 and drill rod 290 and how to replace the drill rod 290, these are existing technologies, and their working principles and structures will not be elaborated here.) Since the conveyor can achieve precise displacement control of the drilling part, it ensures the distance accuracy of the blasting hole, and can accurately open the blasting hole according to the design requirements, thereby improving the reliability of the blasting effect.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
