Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blasting construction, in particular to a semi-automatic rolled explosive filling device. Background Art
[0002] Blasting operations are the energy source of the energy industry and the foundation of basic industries. The construction process includes: blasting design → blasting surface leveling → hole measurement and layout → drilling → drilling inspection → receiving explosives → processing explosive charges → charging → packing → connecting the blasting network → blasting network safety inspection → safety alert → detonation → post-blast inspection and handling → data compilation. These operations require a significant amount of labor, especially charging, which typically requires two or three people to complete, significantly increasing construction safety risks and costs.
[0003] The existing method of loading explosives requires first re-measurement of the blasthole and then lifting the explosives one by one. The operation is very time-consuming and labor-intensive. In addition, during the lifting of the explosives, there is a high possibility that stones on the blasthole wall will fall into the blasthole, which will cause gaps between the explosives, resulting in the failure of the explosives to detonate, and the explosives will remain in the blasthole, which will bury a safety hazard for the subsequent follow-up operations.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present application. The terms used in the description of the present application in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application.
[0030] In the current blasting operation process, a large amount of manual labor is required, especially for charging. Generally, two or three people are needed to complete it, which greatly increases the construction safety hazards and construction costs.
[0031] In view of this, the present utility model provides a coiled explosive loading device. Figures 1-3 This is an embodiment of the coiled explosive loading device provided by the present utility model. Please refer to Figures 1-3 , the device 100 includes a bracket 1, a first component 2, and a second component 3.
[0032] Specifically, the first component 2 is integrally cylindrical and is installed on the bracket 1. The first component 2 includes a housing 21, and an opening 21a for the thin sheet 32 to extend out is provided on the housing 21. The second component 3 is rotatably installed inside the housing 21. The second component 3 includes a reel 31 and a thin sheet 32 wound around the reel 31. Among them, the thin sheet 32 is made of materials such as steel or fiberglass, is soft and bendable, and its cross-section is concave. One end of the thin sheet 32 is fixedly connected to the reel 31. When the thin sheet 32 is being wound up, it can be flattened; when it extends out, the cross-section will return to a concave shape and the extended part remains in a straight shape. The concave groove formed by the thin sheet 32 is used to place the rolled explosive to prevent it from rotating and falling out of the thin sheet 32.
[0033] In the technical solution of the present utility model, by utilizing the winding characteristics of the thin sheet 32 with a concave cross-section, the reel 31 is driven manually or by a machine to unfold the thin sheet 32, and the thin sheet 32 is straightly extended into the blast hole to be blasted along the opening 21a, thereby transporting the explosive on the thin sheet 32 into the blast hole. The device 100 greatly reduces the construction safety hazards and construction costs.
[0034] For facilitating the loading of explosives into blast holes at various angles, please refer to Figure 1 , in an embodiment of the present utility model, the housing 21 includes a first housing 211 connected to the bracket 1 and a second housing 212 movably disposed on the first housing 211, and the opening 21a is provided on the second housing 212. Among them, the first housing 211 is a cylinder installed on the bracket 1, the second housing 212 is annular and sleeved on the first housing 211, the second housing 212 can rotate around the axial direction of the first housing 211, and the position of the opening 21a of the second housing 212 changes during rotation.
[0035] It should be noted that the second housing 212 can be sleeved at both ends of the first housing 211 or in the middle of the first housing 211; when it is sleeved in the middle of the first housing 211, at least part of the middle part of the first housing 211 is cut off so that the opening 21a communicates with the inside of the first housing 211.
[0036] Of course, the implementation manner of the present utility model is not limited to this. The first housing 211 can also be in a flat plate shape, and the second housing 212 is slidably installed on the first housing 211. When it slides, the position of the opening 21a can also be changed.
[0037] For facilitating the adjustment of the housing 21 to be in a horizontal plane, please refer to Figure 1 , in an embodiment of the present utility model, the bracket 1 includes a plurality of telescopic support frames 12, and each support frame 12 is connected to the first housing 211. There are 3 support frames 12 in this embodiment, and each support frame 12 has two sleeves sleeved with each other. After the two sleeves are telescopically adjusted to change the length of the support frame 12, they can be fixed by tightening the bolts.
[0038] Further, please refer to Figure 1 , in an embodiment of the present utility model, a bubble level 213 is provided on the first housing 211. The bubble level 213 relies on gravity induction and displays the horizontal state by determining whether the bubble is in the middle, thereby measuring whether the housing 21 is parallel to the horizontal plane.
[0039] To better adjust the angle of the opening 21a relative to the horizontal plane, please refer to Figure 1 , in an embodiment of the present utility model, a scale is provided on the first housing 211 to indicate the inclination angle of the opening 21a relative to the horizontal plane. It should be noted that when the scale is 0°, the direction in which the sheet 32 extends from the opening 21a on the reel 31 is the horizontal direction.
[0040] It should be understood that, for facilitating the guiding of the sheet 32 to extend from the opening 21a, a guide rail (not shown in the figure) is provided between the reel 31 and the opening 21a to facilitate the conveyance of the sheet 32.
[0041] To enable the reel 31 to rotate, please refer to Figure 1 and 2 , in an embodiment of the present utility model, the first assembly 2 further includes a bearing 22 provided on the housing 21. In this embodiment, the two bearings 22 are respectively installed at both ends of the cylindrical first housing 211, and the reel 31 is connected to the bearing 22 to enable it to rotate relative to the housing 21; in addition, a handle is provided at one end of the reel 31 to facilitate the staff to drive its rotation.
[0042] It should be noted that a cylindrical structure is fixedly installed on the reel 31, and the sheet 32 is wound on this cylindrical structure and is inside the cylindrical first housing 211. In addition, when the sheet 32 is wound, it is restricted inside the housing 21.
[0043] To prevent the explosive from falling when the sheet 32 conveys the rolled explosive, please refer to Figure 3 , in an embodiment of the present utility model, a clamp member 4 is further included. The clamp member 4 is a plastic part, and a bayonet and a clamping block (not shown in the figure) are respectively provided at both ends thereof. The bayonet and the clamping block can move relative to each other in the length direction of the sheet 32 and then be clamped with each other to tie the rolled explosive and the sheet 32 together to fix the rolled explosive placed on the sheet 32.
[0044] To be able to unload the explosive after it enters the blast hole, please refer to Figure 3In one embodiment of the present invention, a pull rod 5 is further provided along the length of the sheet 32 and connected to one end of the clamp 4. When the explosive reaches the bottom of the blasthole, the pull rod 5 is pulled along the length of the sheet 32 to disconnect the clamp block and the bayonet, thereby releasing the clamp 4, allowing the rolled explosive to fall off the sheet 32 and enter the blasthole.
[0045] Preferably, in one embodiment of the present invention, the concave cross section of the sheet 32 is arc-shaped for easy winding. In addition, to prevent static electricity from being generated and causing the explosive to be detonated, the device 100 is made of anti-static material.
[0046] Furthermore, a nut is provided at one end of the thin sheet 32, which is screwed to the reel 31. A screw is also provided at the other end, allowing multiple thin sheets 32 to be fixed to each other via threaded connections. The length of the thin sheet 32 can be set to 0.5 meters or 1 meter, allowing the depth of the blasthole to be repeatedly measured while charging. When interval charging is required, the detonating cord is first secured in the groove of the thin sheet 32, and then the explosives and charge pack are placed according to the design. If the hole depth and angle do not meet the requirements, the blasting operator manually cranks the handle in the opposite direction to remove the explosives from the blasthole. If the hole depth and angle meet the requirements, the thin sheet 32 can be left in the blasthole without removing the clamp 4.
[0047] This device allows one person to complete charge charging, hole depth measurement, and angle measurement. The explosives are secured to the thin sheet 32 before entering the blasthole, preventing explosive refusal due to falling rocks from the hole wall and increasing the safety of subsequent operations. During charge charging, the actual depth of the blasthole can be calculated based on the number of sections of the thin sheet 32 and the length of each section (if the length of the explosive retaining plate is 1 meter and there are 3 sections in the blasthole, the actual depth is 3*1 = 3 meters). The charge quantity can be adjusted based on the actual depth to achieve a better blasting effect. During charge charging, the actual angle of the blasthole can be measured using the scale on the first housing 211, which is particularly important when charging sidewall holes. When staggered charging is required, this can be accomplished using the thin sheet 32. Since the material of the thin sheet 32 is inexpensive, the portion with the explosives secured to it can remain in the blasthole, resulting in more accurate charge spacing. Moreover, the detonating cord can be directly stuck on the sheet 32, eliminating the need to wrap the detonating cord around the explosive with adhesive tape.
[0048] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0049] The above embodiments only represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
