Description

Technical Field

[0001] This utility model relates to the field of tunnel blasting technology, and in particular to a charging tube and charging structure for uncoupled charging. Background Technology

[0002] In engineering blasting operations, techniques such as pre-splitting blasting and smooth blasting are widely used, and decoupled charging is a common charging method in these blasting operations. Decoupled charging refers to a charging method in which the diameter of the explosive inserted into the borehole is smaller than the diameter of the borehole, and a gap is left between the explosive and the inner wall of the borehole. However, currently, the charging tube size used for decoupled charging is fixed, which is only suitable for boreholes of a single size and is difficult to apply to boreholes of different sizes, resulting in poor versatility. Utility Model Content

[0003] The main purpose of this invention is to propose a charging tube and charging structure for uncoupled charges, aiming to solve the technical problem that current charging tubes for uncoupled charges are difficult to apply to boreholes of different sizes and have poor versatility.

[0004] To achieve the above objectives, the present invention proposes a charging tube for uncoupled charging, the charging tube comprising:

[0005] The tube body has a first connecting end and a second connecting end at its two ends along its extension direction. The inner wall of the first connecting end is provided with a first connecting member, and the outer wall of the second connecting end is provided with a second connecting member. The second connecting end can be inserted into the first connecting end of another tube body, and the first connecting member can be connected and cooperated with the second connecting member of yet another tube body.

[0006] A decoupled assembly includes a reinforcing ring and multiple decoupled structures. The multiple decoupled structures are circumferentially spaced on the outer wall of the pipe body. Each decoupled structure includes a movable plate and multiple mounting seats. The multiple mounting seats are axially spaced on the outer wall of the pipe body. The movable plate extends axially along the pipe body and is movably mounted on the multiple mounting seats. The reinforcing ring is mounted on the outer wall of the pipe body and has a clearance groove that matches the shape of the movable plate. The movable plate is disposed within the clearance groove and can move radially relative to each mounting seat towards or away from the pipe body. Each mounting seat has a locking element for locking or unlocking the movable plate.

[0007] In one embodiment, the mounting base includes two seats spaced circumferentially along the tube body, with a movable cavity extending radially along the tube body between the two seats. Each seat has a sliding cavity, which extends along the direction of the movable cavity and communicates with it. A movable plate is disposed within the movable cavity. Two sliding arms are provided on both sides of the movable plate corresponding to the positions of each mounting base. The two sliding arms extend into the two sliding cavities of their respective mounting bases, and each sliding arm can slide within the sliding cavity along the extending direction of the sliding cavity. In each mounting base, at least one seat is equipped with the locking member.

[0008] In one embodiment, each of the mounting bases has two locking members, each of which extends into one of the two sliding cavities and slides into the two sliding cavities respectively. Each locking member can slide along the corresponding sliding cavity and cooperate with the bottom wall of the sliding cavity to clamp or release the sliding arm, thereby locking or unlocking the sliding arm accordingly.

[0009] In one embodiment, the locking member includes a locking rod and a handle. The two ends of the locking rod are a locking end and a toggle end, respectively. The toggle end is connected to the handle, and the locking end extends into the corresponding sliding cavity and slides in cooperation with the sliding cavity. By toggling the handle, the locking rod and its locking end slide along the corresponding sliding cavity, and the sliding arm is clamped or released by the locking end cooperating with the bottom wall of the sliding cavity, thereby locking or unlocking the sliding arm.

[0010] In one embodiment, the bottom wall of the sliding cavity is formed with a plurality of grooves at intervals along the extending direction of the sliding cavity, and the bottom of the sliding arm is formed with a protrusion, and the sliding arm can engage with any of the grooves.

[0011] In one embodiment, the first connector is an internal thread segment, and the second connector is an external thread segment, wherein the internal thread segment and the external thread segment are threadedly engaged.

[0012] In one embodiment, the uncoupled component includes a plurality of reinforcing rings, which are uniformly spaced along the axial direction of the tube body and fitted onto the outer wall of the tube body.

[0013] In one embodiment, one end of the movable plate extends to the first connecting end, and the other end of the movable plate extends to a position close to the second connecting end.

[0014] In one embodiment, the movable plate is a foam board, and the reinforcing ring is a foam ring.

[0015] This utility model also proposes a loading structure for uncoupled loading, the loading structure including a plurality of loading tubes for uncoupled loading as described above, the tube bodies of the plurality of loading tubes being distributed sequentially, and the first connecting end of each tube body being connected to the second connecting end of an adjacent tube body, and the second connecting end of each tube body being connected to the first connecting end of another adjacent tube body.

[0016] The technical solution of this utility model involves placing the tube body into the borehole. Multiple decoupled structures on the outer wall of the tube body, with movable plates abutting against the borehole wall, create a gap between the tube body and the borehole, allowing for decoupled loading of explosives. Since the first connecting end of the tube body can connect and mate with the second connecting end of another tube body, and the second connecting end of that tube body can also connect and mate with the first connecting end of yet another tube body, different lengths of loading structures can be formed by connecting different numbers of tube bodies, thus making it suitable for boreholes of varying depths and offering strong applicability. Furthermore, each decoupled structure includes multiple mounting seats spaced apart along the extension direction of the tube body. The movable plates can be moved radially away from or closer to the tube body and mounted on these mounting seats. These multiple mounting seats ensure a more secure installation of the movable plates onto the outer wall of the tube body, resulting in high structural reliability. Furthermore, by moving the movable plate away from or towards the tube body, and then locking the movable plate with a locking device, the distance between the movable plate and the tube body can be adjusted. This allows the movable plate on the tube body to abut against the borehole walls of different diameters, thus enabling the decoupled charging tube provided by this invention to match boreholes of different diameters, resulting in greater applicability. Therefore, the tunnel blasting method provided by this invention can meet the requirements for decoupled charging of boreholes of different depths and diameters, thereby meeting the needs for decoupled charging of boreholes of different sizes, demonstrating strong applicability.

[0027] In engineering blasting operations, techniques such as pre-splitting blasting and smooth blasting are widely used, and decoupled charging is a common charging method in these blasting operations. Decoupled charging refers to a charging method in which the diameter of the explosive inserted into the borehole is smaller than the diameter of the borehole, and a gap is left between the explosive and the inner wall of the borehole. However, currently, the charging tube size used for decoupled charging is fixed, which is only suitable for boreholes of a single size and is difficult to apply to boreholes of different sizes, resulting in poor versatility.

[0028] This invention proposes a charge tube 100 and a charge structure for uncoupled charge loading.

[0029] Please see Figures 1 to 3In one embodiment of this utility model, the charging tube 100 for decoupled charging includes a tube body 10 and a decoupling component 20; wherein, the two ends of the tube body 10 along its extension direction are a first connecting end 11 and a second connecting end 12, respectively; the inner tube wall of the first connecting end 11 is provided with a first connecting member 111, and the outer tube wall of the second connecting end 12 is provided with a second connecting member 121; the second connecting end 12 can be inserted into the first connecting end 11 of another tube body 10, and the first connecting member 111 can be connected and cooperated with the second connecting member 121 of another tube body 10; the decoupling component 20 includes a reinforcing ring 22 and a plurality of decoupling structures 21, which are installed at intervals along the circumference of the tube body 10. The outer tube wall of the pipe body 10 has a non-coupled structure 21 including a movable plate 212 and multiple mounting seats 211. The multiple mounting seats 211 are spaced apart along the axial direction of the pipe body 10 on the outer tube wall of the pipe body 10. The movable plate 212 extends along the axial direction of the pipe body 10 and is movably mounted on the multiple mounting seats 211. A reinforcing ring 22 is mounted on the outer tube wall of the pipe body 10. The reinforcing ring 22 is provided with a clearance groove. The clearance groove matches the shape of the movable plate 212. The movable plate 212 is disposed in the clearance groove and can move in the radial direction of the pipe body 10 relative to each mounting seat 211 in a direction away from or close to the pipe body 10. Each mounting seat 211 is provided with a locking element 213 for locking or unlocking the movable plate 212.

[0030] The technical solution of this utility model involves placing the tube body 10 into the borehole. The movable plates 212 of multiple decoupled structures 21 on the outer wall of the tube body 10 abut against the borehole wall, creating a gap between the tube body 10 and the borehole. This allows for the decoupled loading of explosives through the tube body 10. Since the first connecting end 11 of the tube body 10 can connect and cooperate with the second connecting end 12 of another tube body 10, and the second connecting end 12 of that tube body 10 can also connect and cooperate with the first connecting end 11 of yet another tube body 10, different lengths of loading structures can be formed by connecting different numbers of tube bodies 10, thus making it suitable for boreholes of different depths and offering strong applicability. Furthermore, each decoupled structure 21 includes multiple mounting seats 211 spaced apart along the extension direction of the tube body 10. The movable plates 212 can be moved radially away from or closer to the tube body 10 and mounted on the multiple mounting seats 211. The multiple mounting seats 211 ensure that the movable plates 212 are more securely mounted to the outer wall of the tube body 10, resulting in high structural reliability. Furthermore, by moving the movable plate 212 away from or towards the tube body 10, and then locking the movable plate 212 with the locking member 213, the distance between the movable plate 212 and the tube body 10 can be adjusted so that the movable plate 212 on the tube body 10 can abut against the borehole wall of different diameters. This allows the charging tube 100 for decoupled charging provided by this invention to be matched with boreholes of different diameters, thus enhancing its applicability. Therefore, the tunnel blasting method provided by this invention can meet the requirements for decoupled charging of boreholes of different depths and diameters, thereby meeting the requirements for decoupled charging of boreholes of different sizes, demonstrating strong applicability. Furthermore, the pipe body 10 is also fitted with multiple reinforcing rings 22. Each reinforcing ring 22 has a clearance groove corresponding to the position of each movable plate 212. The movable plate 212 is set in the clearance groove. Since the shape of the movable plate 212 matches the clearance groove, the clearance groove can provide guidance for the movable plate 212, thereby making the movable plate 212 move more smoothly. In addition, the reinforcing rings 22 can further improve the structural strength of the pipe body 10.

[0031] In one embodiment, the mounting base 211 includes two seat bodies 2111 spaced apart circumferentially along the tube body 10. A movable cavity 214 extending radially along the tube body 10 is formed between the two seat bodies 2111. A sliding cavity 2112 is formed on each seat body 2111. Each sliding cavity 2112 extends along the direction of the movable cavity 214 and communicates with the movable cavity 214. A movable plate 212 is disposed in the movable cavity 214. Two sliding arms 2121 are provided on both sides of the movable plate 212 corresponding to the position of each mounting base 211. The two sliding arms 2121 extend into the two sliding cavities 2112 of their corresponding mounting base 211, and each sliding arm 2121 can slide in the sliding cavity 2112 along the extending direction of the sliding cavity 2112. In each mounting base 211, at least one seat body 2111 is equipped with a locking member 213.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the mounting base 211 includes two seat bodies 2111 axially spaced around the pipe body 10, forming a movable cavity 214 between the two seat bodies 2111. The movable cavity 214 extends radially along the pipe body 10, and a movable plate 212 is disposed within the movable cavity 214. The movable cavity 214 provides guidance for the movement of the movable plate 212, thereby allowing the movable plate 212 to move relatively smoothly along the radial direction of the pipe body 10. Two sliding cavities 2112 are respectively formed on the two seat bodies 2111, and both sliding cavities 2112 communicate with the movable cavity 214. Two sliding arms 2121 on both sides of the movable plate 212, corresponding to the positions of each mounting base 211, extend into the two sliding cavities 2112, and the two sliding arms 2121 can slide along the extension direction of their respective sliding cavities 2112. This allows the movable plate 212 to move radially away from or towards the pipe body 10, with smoother movement.

[0033] In one embodiment, each mounting base 211 has two locking members 213. The two locking members 213 extend into the two sliding cavities 2112 respectively and slide in cooperation with the two sliding cavities 2112 respectively. Each locking member 213 can slide along the corresponding sliding cavity 2112 and cooperate with the bottom cavity wall of the sliding cavity 2112 to clamp or release the sliding arm 2121, thereby locking or unlocking the sliding arm 2121 accordingly.

[0034] Specifically, such as Figure 2 and Figure 3As shown, two locking members 213 are respectively provided on the two seats 2111 of the mounting base 211. Each locking member 213 can move within its corresponding sliding cavity 2112 along the extending direction of the sliding cavity 2112 on its respective seat 2111. When one end of the locking member 213 moves to abut against the top of the sliding arm 2121, the sliding arm 2121 is clamped between the bottom of the locking member 213 and the top of the sliding cavity 2112, thus locking the sliding arm 2121 within the sliding cavity 2112 and locking the movable plate 212. When one end of the locking member 213 moves to disengage from the top of the sliding arm 2121, the clamping of the sliding arm 2121 can be released, and the clamping arm can then slide along the extending direction of the sliding cavity 2112. By moving the locking member 213, the sliding arm 2121 can be locked or unlocked, thereby achieving the locking or unlocking of the movable plate 212, which is simple and convenient.

[0035] In one embodiment, the locking member 213 includes a locking rod 2131 and a handle 2134. The two ends of the locking rod 2131 are a locking end 2132 and a toggle end 2133, respectively. The toggle end 2133 is connected to the handle 2134. The locking end 2132 extends into the corresponding sliding cavity 2112 and slides in cooperation with the sliding cavity 2112. By toggle the handle 2134, the locking rod 2131 and its locking end 2132 slide along the corresponding sliding cavity 2112. The locking end 2132 cooperates with the bottom wall of the sliding cavity 2112 to clamp or release the sliding arm 2121, thereby locking or unlocking the sliding arm 2121.

[0036] Specifically, such as Figure 2 and Figure 3 As shown, the locking lever 2131 extends along the extension direction of its corresponding sliding cavity 2112, with the locking end 2132 and the actuating end 2133 at its two ends along the extension direction, respectively. A handle 2134 is connected to the actuating end 2133, and the locking end 2132 extends into the sliding cavity 2112 and engages with the bottom wall of the sliding cavity 2112 to clamp or release the sliding arm 2121. By actuating the handle 2134, the locking end 2132 can be moved to a point where its bottom abuts against or disengages from the top of the sliding arm 2121, making the process simpler and more convenient.

[0037] In one embodiment, the bottom wall of the sliding cavity 2112 is formed with a plurality of grooves 2113 at intervals along the extending direction of the sliding cavity 2112, and a protrusion 2122 is formed at the bottom of the sliding arm 2121, and the sliding arm 2121 can engage with any of the grooves 2113.

[0038] Specifically, such as Figure 2 and Figure 3As shown, the bottom wall of the sliding cavity 2112 has multiple downwardly recessed grooves 2113 spaced apart along the extending direction of the sliding cavity 2112. Each sliding arm 2121 has a downwardly protruding protrusion 2122 at its bottom end. The protrusion 2122 can engage with each groove 2113. This engagement between the protrusion 2122 and the groove 2113 allows for a more stable and reliable locking of the sliding arm 2121, and also enables more precise control of the moving distance of the movable plate 212, improving adjustment accuracy. It should be noted that after moving the locking end 2132 to the top, disengaging it from the sliding arm 2121, the movable plate 212 needs to be lifted upwards to disengage the protrusion 2122 at the bottom of the sliding arm 2121 from the groove 2113 before the sliding arm 2121 can move along the extending direction of the sliding cavity 2112.

[0039] In one embodiment, the first connector 111 is an internal thread segment, and the second connector 121 is an external thread segment, with the internal thread segment and the external thread segment being threadedly engaged.

[0040] Specifically, such as Figure 1 As shown, the pipe body 10 can be connected to another pipe body 10 by the internal thread section engaging with the external thread section of the other pipe body 10, making the connection simple and convenient.

[0041] In one embodiment, the uncoupled component 20 includes a plurality of reinforcing rings 22, which are uniformly spaced along the axial direction of the pipe body 10 and fitted onto the outer wall of the pipe body 10.

[0042] Specifically, as shown in the figure, multiple reinforcing rings 22 are provided at intervals along the axial direction of the pipe body 10. The clearance grooves on the multiple reinforcing rings 22 can provide better guidance for the movement of the movable plate 212, and the multiple reinforcing rings 22 can further improve the structural strength of the pipe body 10.

[0043] In one embodiment, one end of the movable plate 212 extends to the first connecting end 11, and the other end of the movable plate 212 extends to a position close to the second connecting end 12.

[0044] Specifically, such as Figure 1 As shown, one end of the movable plate 212 extends to the first connecting end 11, and the other end of the movable plate 212 extends to a position close to the second connecting end 12, which can cover the entire length range of the tube body 10. This can effectively reduce the shaking of the tube body 10 in the borehole, and make the charging tube 100 for uncoupled charging provided by this utility model more stable during use.

[0045] In one embodiment, the movable plate 212 is a foam board, and the reinforcing ring 22 is a foam ring. Using a foam board as the movable plate 212 and a foam ring as the reinforcing ring 22 can effectively reduce the weight of the charge tube 100 for uncoupled charge provided by this invention, facilitating transportation. Furthermore, the foam ring and foam board are relatively inexpensive, further reducing the cost of the charge tube 100 for uncoupled charge provided by this invention, resulting in better economic efficiency.

[0046] This utility model also proposes a loading structure for uncoupled charges. The loading structure for uncoupled charges includes a plurality of loading tubes 100 for uncoupled charges. The tube bodies 10 of the plurality of loading tubes 100 are distributed sequentially, and the first connecting end 11 of each tube body 10 is connected to the second connecting end 12 of its adjacent tube body 10. The second connecting end 12 of each tube body 10 is connected to the first connecting end 11 of its adjacent tube body 10. The specific structure of the loading tube 100 for uncoupled charges is as described in the above embodiments. Since this loading structure for uncoupled charges adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
