Description

Technology Field

[0001] The present invention relates to a detonation chamber equipped with a cupola shaking prevention means, and more specifically, to a detonation chamber equipped with a cupola shaking prevention means that prevents a cupola, which is opened and closed during the process of handling aged waste ammunition or organic ammunition, from shaking at a specific opening angle. Background Technology

[0003] While some of the ammunition produced domestically and internationally has been used, a large amount remains stored in ammunition depots. However, as this ammunition deteriorates over time, its performance becomes unreliable, causing it to lose its primary function as ammunition. Furthermore, with the continuous discovery of abandoned bombs—remnants of war—concerns regarding their proper disposal are mounting.

[0004] If such aging or discarded ammunition is disposed of in open natural environments through outdoor detonation or incineration, it causes complex environmental pollution problems. Unlike general waste, ammunition contains various energy materials (high explosives, propellants, etc.), resulting in damage from fire, noise, and vibration, as well as the generation of high concentrations of hazardous substances such as dioxins, volatile organic compounds (VOCs), acid gases, incomplete combustion products, dust, and various heavy metals.

[0005] In order to prevent the above-mentioned problem, a detonation chamber (10) illustrated in FIGS. 1 and FIGS. 2 has been proposed. FIGS. 1 and FIGS. 2 are drawings illustrating a detonation chamber according to the prior art.

[0006] The detonation chamber (10) according to the prior art illustrated in FIG. 1 is a device that safely detonates ammunition to cause it to lose its inherent explosive properties, and may include a cupola (20), a base frame (90) located below the cupola (20) and engaged with the cupola (20), a link member (62, 64, 66) connecting the cupola (20) and the base frame (90), and a rotation locking part (30, Bayonet) that locks or unlocks the cupola (20) and the base frame (90).

[0007] Additionally, it may include a pair of locking / unlocking hydraulic cylinders (40) that rotate the rotary locking part (30) in both directions, and an opening / closing hydraulic cylinder (50) that opens and closes the cupola (20) with respect to the base frame (90).

[0008] Referring to FIG. 2, the rotary locking part (30) is for connecting the cupola (20) and the base frame (90) and can be connected to the lower outer surface of the cupola (20). The rotary locking part (30) rotates by a pair of locking / unlocking hydraulic cylinders (40), and by connecting the gear (not shown) formed on the rotary locking part (30) and the gear (32) formed on the base frame (90), the pressure of hundreds of thousands of bar generated during detonation can be sealed in the detonation chamber (10).

[0009] In addition, since the fragments generated upon the detonation of the ammunition have such tremendous destructive power that they can be used for killing as well as destroying equipment, the detonation chamber (10) can be safely protected from the detonation shock by installing a fragment shield (not shown) on the inner side of the cupola (20) where a lot of detonation shock is applied, and by additionally installing an ammunition installation table (92) on the upper part of the base frame (90) to reinforce the part where the ammunition is installed.

[0010] In the conventional detonation chamber (10), almost all components, including the cupola (20), must be made of a material capable of withstanding explosive shock. For example, it is preferable to manufacture them from steel. A cupola (20) made of steel can weigh about 30 to 35 tons.

[0011] In order to detonate waste ammunition, the cupola (20) is opened by the opening / closing hydraulic cylinder (50), the waste ammunition is placed on the ammunition installation table (92), the cupola (20) is closed by the opening / closing hydraulic cylinder (50), and the rotation locking part (30) is operated by the locking / unlocking hydraulic cylinder (40) so that the cupola (20) and the base frame (90) interlock with each other.

[0012] After the waste ammunition, etc. are detonated, cleaning such as removing fragments is performed with the cupola (20) opened by the opening / closing hydraulic cylinder (50).

[0013] However, when the cupola (20) is opened or closed by the opening / closing hydraulic cylinder (50) and the opening angle of the cupola (20) is about 40 to 45 degrees, a hunting phenomenon occurs in which the cupola (20) shakes about 30 to 35 tons despite the hydraulic pressure of the opening / closing hydraulic cylinder (50) being applied.

[0014] FIGS. 3 and 4 are drawings for explaining the hunting phenomenon that occurs according to the opening angle of the cupola of the detonation chamber according to the prior art. FIGS. 3 and 4 show a schematic diagram for explaining the direction of the force acting on the cupola (20) and the opening / closing hydraulic cylinder (50) while the cupola (20) is open. Here, the connection relationship between the cupola (20), the link members (62, 646, 66), and the opening / closing hydraulic cylinder (50) is represented as a link structure.

[0015] In addition, in FIGS. 3 and 4, COG (Center Of Gravity) refers to the center of gravity of the cupola (20), drawing symbol F refers to the reaction force of the opening / closing hydraulic cylinder (50), and the direction of F refers to the direction of the reaction force.

[0016] FIG. 3(a) shows the cupola (20) engaged with the base frame (90), that is, the cupola (20) is in a closed state. In this state, the weight of the cupola (20) is 30.3 tons, and the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in a direction similar to the axial direction of the opening / closing hydraulic cylinder (50).

[0017] Figure 3(b) shows the cupola (20) in a state where it is opened by 30 degrees. That is, the opening / closing hydraulic cylinder (50) has lifted the cupola (20) by 30 degrees relative to the base frame (90). In this state, the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in a direction almost identical to the axial direction of the opening / closing hydraulic cylinder (50).

[0018] FIG. 4(a) shows the cupola (20) in a state where it is opened at 45 degrees. That is, the opening / closing hydraulic cylinder (50) has lifted the cupola (20) by 45 degrees relative to the base frame (90). In this state, the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in a transverse direction that intersects the axial direction of the opening / closing hydraulic cylinder (50). That is, the reaction force (F) acts in a transverse direction that intersects the axial direction, rather than in the axial direction of the opening / closing hydraulic cylinder (50).

[0019] Figure 4(b) shows the cupola (20) in a state where it is opened 60 degrees. That is, the opening / closing hydraulic cylinder (50) has lifted the cupola (20) by 60 degrees relative to the base frame (90). In this state, the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in a direction opposite to the axial direction of the opening / closing hydraulic cylinder (50). Although the reaction force (F) acts in a direction opposite to the axial direction of the opening / closing hydraulic cylinder (50), the reaction force (F) acts in almost the same line as the axial direction of the opening / closing hydraulic cylinder (50).

[0020] Referring to FIGS. 3 and 4, in the case of FIG. 4 (a), the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in a transverse direction that intersects the axial direction of the opening / closing hydraulic cylinder (50). If we consider the case where the opening angle of the cupola (20) increases continuously from FIG. 3 (a) to FIG. 4 (b), when the opening angle of the cupola (20) becomes about 40 to 45 degrees, the reaction force (F) of the opening / closing hydraulic cylinder (50) changes from the axial direction of the hydraulic cylinder (50) to the transverse direction. When the direction in which the reaction force (F) acts changes from the axial direction of the hydraulic cylinder (50) to the transverse direction, hunting occurs, causing the heavy cupola (20) to shake.

[0021] If a hunting phenomenon occurs where the cupola (20) shakes, it puts a strain on the opening and closing hydraulic cylinder (50), and the operator managing and monitoring the operation of the detonation chamber (10) may feel anxious about the occurrence of an accident.

[0022] Therefore, there is a demand for a detonation chamber in which the hunting phenomenon of the cupola shaking does not occur when the opening angle of the cupola is about 40 to 45 degrees.

[0024] The applicant has proposed the present invention to solve the above-mentioned problems. Prior art literature

[0060] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0061] FIG. 5 is a drawing illustrating a detonation chamber equipped with a cupola shaking prevention means according to an embodiment of the present invention; FIG. 6 is a schematic diagram for explaining a hunting prevention member provided in the detonation chamber according to FIG. 5; FIG. 7 and FIG. 8 are drawings illustrating an example of a hunting prevention member provided in the detonation chamber according to FIG. 5; FIG. 9 is a drawing illustrating another example of a hunting prevention member provided in the detonation chamber according to FIG. 5; FIG. 10 is a drawing illustrating yet another example of a hunting prevention member provided in the detonation chamber according to FIG. 5; FIG. 11 and FIG. 12 are drawings for comparing a hunting phenomenon occurring according to the opening angle of the cupola of a detonation chamber according to the prior art and a detonation chamber according to FIG. 5.

[0062] Referring to FIG. 5, a detonation chamber (100) equipped with a cupola shaking prevention means according to one embodiment of the present invention may include a cupola (120), a base frame (190) located below the cupola (120) and engaged with the cupola (120), a link member (162, 164, 166) connecting the cupola (120) and the base frame (190), and a rotation locking part (130, Bayonet) that locks or unlocks the cupola (120) and the base frame (190).

[0063] Additionally, it may include a pair of locking / unlocking hydraulic cylinders (140) that rotate the rotary locking part (130) in both directions, and an opening / closing hydraulic cylinder (150) that opens and closes the cupola (120) with respect to the base frame (190).

[0064] The rotary locking part (130) is for connecting the cupola (120) and the base frame (190) and can be formed on the lower outer surface of the cupola (120). The rotary locking part (130) rotates by means of a pair of locking / unlocking hydraulic cylinders (140), and by connecting a gear (not shown) formed on the rotary locking part (130) with a gear (132) formed on the base frame (90), the pressure of hundreds of thousands of bar generated during detonation can be sealed in the detonation chamber (100).

[0065] In addition, since the fragments generated upon the detonation of ammunition have such tremendous destructive power that they can be used for killing as well as destroying equipment, the detonation chamber (100) can be safely protected from the detonation shock by installing a fragment shield (not shown) on the inner side of the cupola (120) where a large amount of detonation shock is applied, and by additionally installing an ammunition installation table (192) on the upper part of the base frame (190) to reinforce the part where the ammunition is installed.

[0066] As illustrated in FIG. 5, a detonation chamber (100) having a cupola shaking prevention means according to one embodiment of the present invention may include: a base frame (190); a cupola (120) rotatably provided with respect to the base frame (190); an opening / closing hydraulic cylinder (150) for opening / closing the cupola (120) with respect to the base frame (190); and a hunting prevention part (170) connecting the opening / closing hydraulic cylinder (150) and the base frame (190).

[0067] A detonation chamber (100) according to one embodiment of the present invention is provided with a hunting prevention part (170) configured to connect an opening / closing hydraulic cylinder (150) and a base frame (190), thereby removing the lateral load generated in the opening / closing hydraulic cylinder (150) or changing the direction of action of the reaction force (F) of the opening / closing hydraulic cylinder (150) from the lateral direction to the axial direction of the opening / closing hydraulic cylinder (150).

[0068] Referring to FIG. 5, the point where the hunting prevention part (170) and the opening / closing hydraulic cylinder (150) are connected is indicated by the drawing symbol "E".

[0069] FIG. 6 shows a schematic diagram of a detonation chamber (100) according to one embodiment of the present invention, in which a hunting prevention part (170) is formed, in the form of a link structure.

[0070] Referring to FIG. 6, the hunting prevention part (170) is connected to the opening / closing hydraulic cylinder (150). When the opening / closing hydraulic cylinder (150) is represented as a link structure, the point (E) where the hunting prevention part (170) and the opening / closing hydraulic cylinder (150) are connected is preferably located at a point approximately 1 / 3 of the length from the bottom of the link structure of the opening / closing hydraulic cylinder (150).

[0071] In one embodiment of the present invention, the detonation chamber (100) is provided with a hunting prevention part (170) connecting the opening / closing hydraulic cylinder (150) and the base frame (190), so that the direction in which the reaction force (F) of the opening / closing hydraulic cylinder (150) acts does not deviate significantly from the axial direction of the opening / closing hydraulic cylinder (150). In FIG. 6, the longitudinal direction of the link structure schematically representing the opening / closing hydraulic cylinder (150) represents the axial direction of the opening / closing hydraulic cylinder (150).

[0072] A hunting prevention member (170) of a detonation chamber (100) according to one embodiment of the present invention can remove the lateral load generated in the opening / closing hydraulic cylinder (150) while the cupola (120) is opened at an angle of 40 to 45 degrees relative to the base frame (190), or change the direction of the reaction force (F) of the opening / closing hydraulic cylinder (150). Here, "lateral load" refers to a force that causes the reaction force (F) of the opening / closing hydraulic cylinder (150) to act in a direction that intersects or deviates from the axial direction.

[0073] In the detonation chamber (100) according to one embodiment of the present invention, when the cupola (120) is opened and the opening angle becomes 40 to 45 degrees, the hunting prevention member (170) applies a tensile force to the opening / closing hydraulic cylinder (150), thereby preventing the direction of action of the reaction force (F) of the opening / closing hydraulic cylinder (150) from deviating from the axial direction or from acting in a transverse direction that intersects the axial direction. In this way, by causing the reaction force (F) of the opening / closing hydraulic cylinder (150) to act along the axial direction by the hunting prevention member (170), the hunting phenomenon in which the cupola (120) shakes when the opening angle of the cupola (120) becomes 40 to 45 degrees is prevented.

[0074] FIGS. 7 and FIGS. 8 illustrate an example of a hunting prevention unit (170, 270) provided in a detonation chamber (100) according to one embodiment of the present invention.

[0075] Referring to FIG. 7(a), the opening and closing hydraulic cylinder (150) may include a cylinder housing (151) and an operating piston (152) with its lower end inserted into the cylinder housing (151). Hydraulic fluid supplied through a hydraulic circuit may flow into or out of the cylinder housing (151). The operating piston (152), with its lower end inserted into the cylinder housing (151), moves forward or backward relative to the cylinder housing (151) by means of the hydraulic fluid flowing into or out of the cylinder housing (151).

[0076] A connection portion (159) for connection with link members (164, 166) may be formed at the top of the operating piston (152). A bottom connection portion (158) for connection with a base frame (190) may be formed at the bottom of the cylinder housing (151). An outer connection portion (157) to which one end of a hunting prevention portion (170) is connected may be formed on the outer surface of the cylinder housing (151).

[0077] The hunting prevention part (170) may include a tension spring (171), a first connecting part (178) formed at the top of the tension spring (171), and a second connecting part (179) formed at the bottom of the tension spring (171). The second connecting part (179) may be connected to a base frame (190), and the first connecting part (178) may be connected to an outer connecting part (157) of a cylinder housing (151).

[0078] The point where the outer connecting part (157) of the cylinder housing (151) and the first connecting part (178) of the hunting prevention part (170) are connected becomes point E. Here, point E can be located at a point that is 1 / 3 of the total length of the opening / closing hydraulic cylinder (150) including the cylinder housing (151) and the operating piston (152), that is, at a point that is 1 / 3 of the total length of the opening / closing hydraulic cylinder (150) from the lower connecting part (158).

[0079] The hunting prevention unit (170) can apply a tensile force to the opening / closing hydraulic cylinder (150). To this end, the hunting prevention unit (170) may include a tension spring (171) with both ends (178, 179) respectively connected to the cylinder housing (151) and the base frame (190) of the opening / closing hydraulic cylinder (150).

[0080] When the tension spring (171) of the hunting prevention unit (170) is stretched, the elastic restoring force that attempts to return it to its original state acts in the opposite direction to the direction of stretching. Therefore, when the tension spring (171) of the hunting prevention unit (170) connected to the cylinder housing (151) is stretched, a tension force (tension) acts on the cylinder housing (151), causing the opening / closing hydraulic cylinder (150) to be pulled by the hunting prevention unit (170).

[0081] Referring to FIG. 7(b), the hunting prevention part (270) may be provided in the form of a hydraulic cylinder. The hunting prevention part (270) provided in the form of a hydraulic cylinder may include a cylinder housing (271), a piston rod (273) with one end inserted into the cylinder housing (271), a first connecting part (278) formed at the top of the piston rod (273), and a second connecting part (279) formed at the bottom of the cylinder housing (271). The second connecting part (279) may be connected to a base frame (190), and the first connecting part (278) may be connected to an outer connecting part (157) of the cylinder housing (151) of the opening / closing hydraulic cylinder (150).

[0082] The point where the outer connecting part (157) of the cylinder housing (151) of the opening / closing hydraulic cylinder (150) and the first connecting part (278) of the hunting prevention part (270) are connected becomes point E. Here, point E can be located at a point that is 1 / 3 of the total length of the opening / closing hydraulic cylinder (150) including the cylinder housing (151) and the operating piston (152), that is, at a point that is 1 / 3 of the total length of the opening / closing hydraulic cylinder (150) from the lower connecting part (158).

[0083] The hunting prevention part (270) can apply a tensile force to the opening / closing hydraulic cylinder (150). To this end, the hunting prevention part (270) may be provided in the form of a hydraulic cylinder comprising a piston rod (273) and a cylinder housing (270), with both ends (278, 279) respectively connected to the cylinder housing (151) and the base frame (190) of the opening / closing hydraulic cylinder (150).

[0085] Additionally, as shown in FIG. 8 (a), a hunting prevention member (170) or a tension spring (171) may be provided as a pair on both sides along the diameter direction of the cylinder housing (151).

[0086] Likewise, as illustrated in FIG. 8(b), the hunting prevention unit (270) may include a pair of hydraulic cylinders provided on both sides along the diameter direction of the cylinder housing (151).

[0087] Meanwhile, referring to FIG. 9(a), the hunting prevention part (170) may include a cylinder bracket (180) connected to the cylinder housing (151) of the opening / closing hydraulic cylinder (150) and a tension spring (171) with both ends connected to the cylinder bracket (180) and the base frame (190).

[0088] As shown in FIG. 7(a), if the hunting prevention part (170) or the tension spring (171) is directly connected to the cylinder housing (151) of the opening / closing hydraulic cylinder (150), there is a possibility that the cylinder housing (151) may be deformed or damaged due to the tension of the tension spring (171). If the cylinder housing (151) is deformed or damaged, the opening / closing hydraulic cylinder (150) cannot operate normally, which may lead to a failure of the detonation chamber (100). Therefore, to prevent the cylinder housing (151) from being deformed or damaged, a separate cylinder bracket (180) may be provided on the outside of the cylinder housing (151) as shown in FIG. 9, and the hunting prevention part (170) or the tension spring (171) may be connected to the cylinder bracket (180).

[0090] Referring to FIG. 9(a), the cylinder bracket (180) may include a support member (181) connected to the bottom of the cylinder housing (151) and an extension member (183) that is bent at one end of the support member (181) and extends along the longitudinal direction of the cylinder housing (151).

[0091] The support portion (181) of the cylinder bracket (180) is provided to support the lower end of the cylinder housing (151), and the lower connecting portion (158) formed at the lower end of the cylinder housing (151) may be provided to pass through the support portion (181). The lower end of the cylinder housing (151) and the support portion (181) may be fixed to each other by welding or the like.

[0092] The extension portion (183), which is formed by bending at one end of the support portion (181) and extending along the longitudinal direction of the cylinder housing (151), is preferably formed with a curved surface identical to the outer surface of the cylinder housing (151).

[0093] The lower end of the extension part (183) is connected to the support part (181), and since the hunting prevention part (170) or the tension spring (171) is connected to the extension part (183), a pulling force (tension or tensile force) is applied to the extension part (183). Since the extension part (183) is formed as a curved surface, the degree of deformation of the upper end with respect to the lower end connected to the support part (181) can be reduced.

[0094] An outer connection part (187) to which a hunting prevention part (170) or a tension spring (171) is connected may be formed on the outer surface of the extension part (183). The first connection part (178) of the tension spring (171) may be connected to the outer connection part (187) of the cylinder bracket (180). Thus, the outer connection part (187) of the cylinder bracket (180) may become the E point.

[0095] Meanwhile, the extension (183) of the cylinder bracket (180) is provided spaced apart from the cylinder housing (151), and both ends (178, 179) of the tension spring (171) can be connected to the extension (183) and the base frame (190).

[0096] If the extension part (183) is in contact with the cylinder housing (151), deformation or damage may occur to the cylinder housing (151) due to deformation of the extension part (183). To prevent such problems, it is preferable that the cylinder housing (151) and the extension part (183) be spaced apart from each other.

[0097] A hunting prevention member (170) or a tension spring (171) may be provided as a pair on both sides of the cylinder bracket (180) along the diameter direction of the cylinder housing (151).

[0098] Referring to FIG. 9(b), the hunting prevention part (270) can be provided in the form of a hydraulic cylinder connected to a cylinder bracket (180).

[0099] A hunting prevention member (270) provided in the form of a hydraulic cylinder may include a cylinder housing (271), a piston rod (273) with one end inserted into the cylinder housing (271), a first connecting member (278) formed at the upper end of the piston rod (273), and a second connecting member (279) formed at the lower end of the cylinder housing (271). The second connecting member (279) may be connected to a base frame (190), and the first connecting member (278) may be connected to an outer connecting member (187) of a cylinder bracket (180).

[0100] A hunting prevention part (270) or a hydraulic cylinder may be provided as a pair on both sides of the cylinder bracket (180) along the diameter direction of the cylinder housing (151).

[0102] Referring to FIG. 10 (a), the hunting prevention unit (170) may include a storage casing (210) in which the cylinder housing (151) of the opening / closing hydraulic cylinder (150) is housed, and a tension spring (171) with both ends connected to the storage casing (210) and the base frame (190).

[0103] The storage casing (210) is a hollow cylindrical member. The top of the storage casing (210) is open, and the bottom surface can be connected and fixed to the bottom of the cylinder housing (151). A bottom connecting portion (158) formed at the bottom of the cylinder housing (151) can be provided to pass through the bottom surface of the storage casing (210). The bottom of the cylinder housing (151) and the bottom surface of the storage casing (210) may be fixed to each other by welding or the like.

[0104] The storage casing (210) has a lower surface connected to the bottom of the cylinder housing (151), and an outer connection part (217) to which a hunting prevention part (170) or a tension spring (171) is connected may be formed on the outer surface of the storage casing (210). The first connection part (178) of the tension spring (171) may be connected to the outer connection part (217) of the storage casing (210). Thus, the outer connection part (217) of the storage casing (210) may become the E point.

[0105] Meanwhile, the outer surface of the cylinder housing (151) and the inner surface of the storage casing (210) may be provided in a spaced-apart state.

[0106] If the storage casing (210) is in contact with the cylinder housing (151), deformation or damage may occur to the cylinder housing (151) due to deformation of the storage casing (210). To prevent such problems, it is preferable that the cylinder housing (151) and the storage casing (210) be spaced apart from each other.

[0107] A hunting prevention part (170) or a tension spring (171) may be provided as a pair on both sides of the storage casing (210) along the diameter direction of the cylinder housing (151).

[0108] If the tension of the tension spring (171) of the hunting prevention part (170) is 1.5 tons, it is preferable that the maximum deformation amount (maximum elongation amount) of the tension spring (171) be about 200 mm. By using a tension spring (171) having such mechanical characteristics, the hunting phenomenon that shakes when the cupola (120) is opened to about 40 to 45 degrees can be prevented.

[0109] Additionally, referring to Fig. 10 (b), the hunting prevention part (270) may be provided in the form of a hydraulic cylinder connected to the storage casing (210).

[0110] A hunting prevention member (270) provided in the form of a hydraulic cylinder may include a cylinder housing (271), a piston rod (273) with one end inserted into the cylinder housing (271), a first connecting member (278) formed at the upper end of the piston rod (273), and a second connecting member (279) formed at the lower end of the cylinder housing (271). The second connecting member (279) may be connected to a base frame (190), and the first connecting member (278) may be connected to an outer connecting member (217) of a storage casing (210).

[0111] As illustrated in FIG. 7(b), FIG. 8(b), FIG. 9(b) and FIG. 10(b), the hunting prevention part (270) may be provided in the form of a hydraulic cylinder including a cylinder housing (271) and a piston rod (273). Since the pressure changes according to the change in weight when the hydraulic pressure of the operating fluid acting on the opening / closing hydraulic cylinder (150) changes from positive to negative, a bracket (not shown) may be installed on the outside of the opening / closing hydraulic cylinder (150) and a hydraulic cylinder of about 2 to 3 tons may be installed to prevent the hunting phenomenon of the cupola (20).

[0113] Meanwhile, the detonation chamber (100) according to one embodiment of the present invention may further include a holding valve (not shown, Holding Valve) provided in the hydraulic circuit of the opening / closing hydraulic cylinder (150) in addition to the hunting prevention part (170) that pulls the opening / closing hydraulic cylinder (150) against the base frame (190).

[0114] The above holding valve is a valve that prevents the natural downward movement of the operating piston (152) due to the leakage of operating fluid at the neutral position (position where the hydraulic pressure changes from positive to negative) of the opening / closing hydraulic cylinder (150) and controls the flow rate when the opening / closing hydraulic cylinder (150) is operated. In one embodiment of the present invention, the detonation chamber (100) can prevent the hunting phenomenon twice by installing the above holding valve in the hydraulic circuit of the opening / closing hydraulic cylinder (150) in addition to the hunting prevention part (170) including a tension spring (171).

[0116] Meanwhile, FIGS. 11 and 12 are drawings for comparing the hunting phenomenon that occurs according to the opening angle of the cupola of a detonation chamber (10) according to the prior art and a detonation chamber (100) according to one embodiment of the present invention.

[0117] FIG. 11(a) is a schematic diagram showing how the direction of the reaction force (F) acting on the opening / closing hydraulic cylinder (50) changes according to the opening angle of the cupola (20) in the detonation chamber (10) according to the prior art shown in FIG. 1 and 2, and FIG. 11(b) is a schematic diagram showing how the direction of the reaction force (F) acting on the opening / closing hydraulic cylinder (150) changes according to the opening angle of the cupola (120) in the detonation chamber (100) according to one embodiment of the present invention shown in FIG. 5. In FIG. 11(a), the longitudinal direction of the link structure schematically representing the opening / closing hydraulic cylinder (50) represents the axial direction of the opening / closing hydraulic cylinder (50), and in FIG. 11(b), the longitudinal direction of the link structure schematically representing the opening / closing hydraulic cylinder (150) also represents the axial direction of the opening / closing hydraulic cylinder (150).

[0118] Referring to FIG. 11 (a), it can be seen that when the opening angle of the cupola (20) is 45 degrees, the reaction force (F) of the opening / closing hydraulic cylinder (50) acts in the axial direction of the opening / closing hydraulic cylinder (50). On the other hand, referring to FIG. 11 (b), it can be seen that even when the opening angle of the cupola (120) is 45 degrees, the reaction force (F) of the opening / closing hydraulic cylinder (150) acts in the axial direction of the opening / closing hydraulic cylinder (150).

[0119] As illustrated in Fig. 11(b), the detonation chamber (100) according to one embodiment of the present invention is equipped with a hunting prevention part (170, 270) connecting the opening / closing hydraulic cylinder (150) and the base plate (190), so that the reaction force (F) of the opening / closing hydraulic cylinder (150) acts in the axial direction of the opening / closing hydraulic cylinder (150) regardless of the opening angle of the cupola (120), so the hunting phenomenon of shaking the cupola (120) does not occur.

[0120] FIG. 12 (a) is a schematic diagram of a link structure in which the center of gravity of the cupola (20, 120) of the detonation chamber (10, 100) is F, the link member (62, 162) directly connected to the cupola is A, the link member (66, 166) to which the opening / closing hydraulic cylinder (50, 150) is connected is B, and the opening / closing hydraulic cylinder (50, 150) is C.

[0121] FIG. 12(b) shows the direction of the reaction force of the opening / closing hydraulic cylinder (C) when the opening angle of the cupola (F) of the detonation chamber (10) according to the prior art shown in FIG. 1 and 2 is 0 degrees, 45 degrees, and 60 degrees. FIG. 12(c) shows the direction of the reaction force of the opening / closing hydraulic cylinder (C) and the direction of the tension (P) of the hunting prevention part (170) when the opening angle of the cupola (F) of the detonation chamber (100) according to one embodiment of the present invention shown in FIG. 5 is 0 degrees, 45 degrees, and 60 degrees.

[0122] In the case of Fig. 12 (b), when the opening angle of the cupola (F) is 45 degrees, the reaction force (see arrow) of the opening / closing hydraulic cylinder (C) acts in the axial and transverse directions, causing the cupola (F) to shake and resulting in a hunting phenomenon.

[0123] In the case of (c) of FIG. 12, when the opening angle of the cupola (F) is 45 degrees, the tension (P) of the hunting prevention part (170) acts transversely to the axial direction of the opening / closing hydraulic cylinder (C), so the reaction force (see arrow) of the opening / closing hydraulic cylinder (C) acts in the axial direction of the opening / closing hydraulic cylinder (C), and the hunting phenomenon of the cupola (F) shaking does not occur.
