Description

Technical Field

[0001] The utility model relates to the technical field of blasting auxiliary devices, in particular to an air-spaced charging auxiliary device. Background Art

[0002] Spaced charge, also known as spaced charge or air-spaced charge, is a unique explosives configuration method in blasting technology. This method divides the explosive column into several sections and uses a medium such as air, water, or rock slag as a separator. Based on the principle of sympathetic detonation, this method scientifically distributes the explosive energy within the blasthole.

[0003] The current air-spaced charge system uses an airbag containing a container specifically designed to hold the chemical agent. A trigger button is installed on the container. Pressing the trigger button instantly mixes the chemicals, causing a chemical reaction that rapidly releases gas and inflates the airbag. In practice, a tow rope is attached to the top of the airbag, allowing a worker to press the button to initiate the mixing of the chemicals and then lower the airbag into the blasthole. The worker then holds the tow rope and lowers the airbag to the desired depth in the blasthole. The explosive column is then placed above the airbag.

[0004] However, existing methods present several issues. Lowering the airbag relies entirely on manual release of the traction rope, making it difficult to achieve a quick and smooth lowering and potentially resulting in inaccurate positioning. Furthermore, handling the traction rope can be challenging. Directly dropping it into the blasthole could interfere with the subsequent blasting process; forcibly ripping it could damage the airbag, causing air leaks and compromising the blasting effectiveness.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: An air gap charge assist device, such as Figure 1-Figure 4 As shown, it includes a base plate 1, a support plate 2, a mounting plate 21 and a walking wheel 22. Four support plates 2 are fixedly connected to the top of the base plate 1 at intervals. The tops of the four support plates 2 are commonly fixedly connected to the mounting plate 21. The bottom of the base plate 1 is fixedly connected to four walking wheels 22 at intervals. It also includes a winding assembly, a clamping assembly and a positioning assembly. A winding assembly is provided on the top of the mounting plate 21. A clamping assembly and a positioning assembly are provided on the winding assembly. An airbag is clamped and fixed on the clamping assembly. The winding assembly is used to drive the airbag to rise and fall, and the positioning assembly is used to position the lifting distance of the airbag.

[0022] like Figure 1 and Figure 2As shown, the winding assembly includes a mounting base 31, a rotating shaft 32, a servo motor 321, a winding wheel 33, a cable 34, a mounting bracket 35, a fixed shaft 36 and a guide wheel 37. The mounting base 31 is fixedly connected to the top of the mounting plate 21, and the upper part of the mounting base 31 is rotatably connected to the rotating shaft 32. The servo motor 321 is installed on the right side of the mounting base 31, and the output shaft end of the servo motor 321 is fixedly connected to the right end of the rotating shaft 32. The winding wheel 33 is fixedly connected to the rotating shaft 32, and the cable 34 is wound on the winding wheel 33. The mounting brackets 35 are fixedly connected to the left and right sides of the upper part of the mounting base 31, and the fixed shaft 36 is fixedly connected between the upper parts of the two mounting brackets 35. The middle part of the fixed shaft 36 is rotatably connected to the guide wheel 37.

[0023] like Figure 2 and Figure 3 As shown, the clamping assembly includes a connecting seat 41, an electric push rod 42 and a connecting ring 43. The end of the movable end of the cable 34 is fixedly connected to the connecting seat 41, the electric push rod 42 is installed on the connecting seat 41, and the top of the airbag is fixedly connected to the connecting ring 43. The telescopic rod of the electric push rod 42 can be inserted into the connecting ring 43 to fix the airbag.

[0024] like Figure 2 As shown, the positioning assembly includes a fixed plate 51, a guide sleeve 52, a camera 53, a marking ring 54 and a control panel 38. The middle parts of the two mounting brackets 35 are fixedly connected with a fixed plate 51, and a guide sleeve 52 is fixedly connected between the two fixing plates 51. The camera 53 is installed on the right fixing plate 51 near the guide sleeve 52. Marking rings 54 are provided on the cable 34 every half meter. The control panel 38 is installed on the top of the mounting plate 21. The control panel 38 is electrically connected to the servo motor 321, the camera 53 and the electric push rod 38.

[0025] First, the staff moves the device to the blasting hole, starts the electric push rod 42 through the control panel 38, and retracts the telescopic rod of the electric push rod 42. Then, the connecting ring 43 on the airbag is inserted into the connecting seat 41, and then the telescopic rod of the electric push rod 42 is controlled to extend to clamp the connecting ring 43 to ensure that the airbag is stably fixed. At this time, the bottom of the airbag should be adjusted to be roughly aligned with the blasting hole. Next, the distance the airbag needs to be lowered is set on the control panel 38. After the setting is completed, the staff presses the switch in the airbag, and the control panel 38 controls the servo motor 321 to start. The servo motor 321 then drives the rotating shaft 32 to rotate, thereby driving the winding wheel 33 to start rotating, releasing the cable wound on it. 34. Under the influence of the clamping assembly and the gravity of the airbag, as well as the precise guidance of the guide wheel 37 and guide sleeve 52, the cable 34 gradually moves downward along the blasthole. During the movement of the cable 34, the camera 53 constantly monitors and records the marker ring 54 on the cable 34. When the camera 53 detects the marker ring 54 corresponding to the set distance, it immediately sends a signal to the control panel 38, which then controls the servo motor 321 to shut off, allowing the airbag to accurately reach the predetermined position. After the gas in the airbag is completely released and the airbag is expanded to tightly block the blasthole, the control panel 38 controls the telescopic rod of the electric push rod 42 to retract, thereby releasing the clamp on the connecting ring 43. At the same time, the control panel 38 controls the output shaft of the servo motor 321 to rotate in the opposite direction, rewinding the cable 34 onto the reel 33. In this way, the present device can quickly and accurately install the airbag and simultaneously rewind the cable 34 in an orderly manner, effectively avoiding the adverse effects that may be caused by the use of traditional connecting ropes.

[0026] like Figure 2 and Figure 3 As shown, a counterweight ring 6 is also included. The top of the connecting seat 41 is fixedly connected to the counterweight ring 6, and the cable 34 can pass through the counterweight ring 6.

[0027] By providing the counterweight ring 6 , the weight of the connecting seat 41 is further increased, thereby ensuring that the end of the cable 34 is more stable and less likely to shake when being retracted upward.

[0028] like Figure 1 and Figure 4 As shown, it also includes a placement frame 71 and a placement plate 72 . The placement frame 71 is fixedly connected to the top front side of the mounting plate 21 , and the placement plate 72 is fixedly connected to the placement frame 71 .

[0029] By providing the placement frame 71 and the placement plate 72 , when the device is not in use or is moved, the counterweight ring 6 can be clamped on the placement plate 72 , thereby fixing the electric push rod 42 and the like.

[0030] like Figure 1 and Figure 4As shown, it also includes a fixing ring 81, an insertion rod 82 and a pedal 83. The fixing ring 81 is fixedly connected to the support plate 2 at the rear side, and an insertion rod 82 is movably inserted at the rear side of the base plate 1. The top of the insertion rod 82 is fixedly connected to the pedal 83.

[0031] When installing the airbag at the blasting hole, the staff can also use the fixing ring 81, the insertion rod 82 and the pedal 83 to limit the device. The specific method is: first remove the insertion rod 82 from the fixing ring 81, then insert it into the back side of the base plate 1, and then step on the pedal 83 to insert the insertion rod 82 deeply into the soil, so as to achieve a stable limit on the base plate 1 and prevent the base plate 1 from moving during operation.

[0032] like Figure 1 As shown, a handle 9 is also included. The handle 9 is fixedly connected between the upper parts of the two support plates 2 at the rear side. The handle 9 is provided to facilitate the staff to move the device.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
