Description

Technical Field

[0001] The present invention belongs to the technical field of large-volume charge shells, relates to charge shells, and particularly relates to a large-volume charge shell with safe flipping for remote operation. Background Art

[0002] Both the explosion water mist dust removal bomb and the fire extinguishing bomb are filled with liquid-phase materials. Through the explosion-driven loading effect of the scattered explosive, the liquid-phase materials are scattered into the air to form a cloud mass covering a certain spatial range. The effects of the explosion water mist dust removal bomb and the fire extinguishing bomb increase with the increase in the diameter of the scattered cloud mass. In order to increase the diameter of the cloud mass formed by the scattering of the liquid-phase materials, the explosion water mist dust removal bomb and the fire extinguishing bomb are usually designed as thin-walled shell structures. As little energy as possible released by the explosion of the scattered explosive is used for shell rupture, and as much as possible is used to drive and load the liquid-phase materials to do work, thereby increasing the scattering speed of the liquid-phase materials and increasing the diameter of the scattered cloud mass. Therefore, the macroscopic structure of the explosion water mist dust removal bomb and the fire extinguishing bomb is a thin-walled shell structure filled with liquid-phase materials.

[0003] For the thin-walled shell filled with liquid-phase materials, its aspect ratio has a greater impact on the shape of the scattered cloud mass. Hui Junming et al. reported in the literature "Experimental Study on the Influence of FAE Device Parameters on Fuel Scattering and Explosion Power" (High Pressure Physics, June 2004, Vol. 18, No. 2, p. 105): For a cylindrical thin-walled shell filled with liquid-phase materials, when the aspect ratio is properly selected, the shape of the cloud mass formed by the scattering of the explosive is more ideal, and the concentration distribution of the cloud mass is more uniform. Through comprehensive investigation, an aspect ratio of 3 to 5 is better, and the size design of the thin-walled shell filled with liquid-phase materials can be selected within this range.

[0004] With the development of related products of thin-walled shells filled with liquid-phase materials, the filling volume of the liquid-phase materials is getting larger and larger, and the total weight of the thin-walled shells filled with liquid-phase materials increases accordingly. Currently, the weight of such products has reached the ten-ton level. The diameter of the ten-ton thin-walled shell filled with liquid-phase materials is about 2 meters, and the length is about 8 meters. During transportation, in order to ensure stable transportation, the shell lies down with its axis parallel to the horizontal plane. When filling the liquid-phase materials into the thin-walled shell, in order to ensure the stability and full filling of the shell during filling, the shell stands up with its axis perpendicular to the horizontal plane. When using this product, in order to increase the coverage range of the scattered cloud mass, the shell stands up with its axis perpendicular to the horizontal plane. Therefore, the thin-walled shell filled with liquid-phase materials needs to be repeatedly flipped from lying down to standing up during liquid filling, transportation, and use.

[0005] The flipping of a ten-ton shell cannot be completed by manual operation alone and must rely on corresponding auxiliary assembly machinery support equipment to be carried out safely, reliably and efficiently. Zhang Yumei et al. reported a multi-degree-of-freedom flipping vehicle in the literature "Application of Multi-Degree-of-Freedom Flipping Vehicle in Satellite Assembly" (Machinery Manufacturing, August 2018, Vol. 56, No. 648, page 89), which consists of a push rod, a flipping frame and an adapter. By the telescopic and swinging of the push rod, the adapter is driven to flip, which can meet the flipping of the adapter from 0 to 90°. The flipping process of the vehicle for the shell is as follows: The shell is fixed on the flipping vehicle, and the outer wall of the shell is connected to the flipping vehicle through several points. By applying a flipping moment to the shell through the flipping vehicle, the shell undergoes a spatial flipping motion, and finally the flipping work is completed.

[0006] However, when using this flipping vehicle to flip a ten-ton thin-walled shell filled with liquid phase material, the following problems occurred: When the flipping vehicle completes the spatial flipping work of the shell, it can only ensure that the shell is flipped to the required angle, and it is impossible to accurately control the speed of the shell during the flipping process. There are large mutations in the speed at the beginning and end stages of the shell flipping. Since the weight of the shell is as high as ten tons, the mutation of the speed during the flipping process will bring a great inertial load. The flipping vehicle and the shell are only fixedly connected through several points, and the great inertial load acts on these points, and the force borne by each point is very large. And the shell is a thin-walled shell, and too large an external force will cause insufficient strength and damage of the shell, and then lead to leakage of the internal liquid phase material, resulting in the failure of the thin-walled shell filled with liquid phase material. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a remotely operated and safely flipped large-volume charge shell to solve the technical problem of the failure of the charge shell due to speed mutation during the flipping process in the existing technology.

[0008] To solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0009] A remotely operated and safely flipped large-volume charge shell, including a cylindrical shell, the cylindrical shell includes a top flange, an outer shell and a bottom flange connected in sequence from top to bottom. The outer diameters of the top flange, the outer shell and the bottom flange are equal. The inner diameters of the top flange and the bottom flange are smaller than the inner diameter of the outer shell, and the inner diameters of the top flange and the bottom flange are equal. A plurality of threaded through holes are evenly axially opened around the circumference of the top flange, and positioning screws are installed in the threaded through holes.

[0010] It also includes an upper end cover. The side surface of the upper end cover is in sliding fit contact with the inner upper surface of the outer housing. A throwing tube installation hole is axially opened in the center of the upper end cover. The upper end of the throwing tube is installed in the throwing tube installation hole. The upper end surface of the upper end cover is flush with the upper end surface of the throwing tube. The lower end of the throwing tube is connected to the lower end cover. The side surface of the lower end cover is in sliding fit contact with the inner lower surface of the outer housing.

[0011] The side surface of the throwing tube is provided with an upper circular ring and a lower circular ring. The upper circular ring is located in the upper middle part of the throwing tube, and the lower circular ring is located in the lower middle part of the throwing tube. The upper circular ring is connected to one end of a plurality of upper circular rods evenly distributed in the circumferential direction. The other end of the upper circular rod is connected to the inner surface of the upper end cover. The lower circular ring is connected to one end of a plurality of lower circular rods evenly distributed in the circumferential direction. The other end of the lower circular rod is connected to the inner surface of the lower end cover. The upper circular ring and the lower circular ring are connected by a plurality of circular arc rods evenly distributed in the circumferential direction.

[0012] A temporary baffle is detachably installed at the lower end of the bottom flange. The temporary baffle, the bottom flange and the lower end cover enclose a high-pressure gas chamber. An inflation through hole is radially provided on the bottom flange. An inflation pipe is installed in the inflation through hole. One end of the inflation pipe extends into the high-pressure gas chamber, and an inflation switch is provided at the other end of the inflation pipe.

[0013] The outer housing, the upper end cover, the throwing tube and the lower end cover enclose a sealed liquid chamber.

[0014] The present invention also has the following technical features:

[0015] A plurality of annular bosses are respectively provided in the middle part of the outer housing. The annular bosses are located in the sealed liquid chamber. Threaded blind holes are provided in the middle part and the annular bosses of the outer housing, and lifting rings are installed in the threaded blind holes.

[0016] The lifting ring includes a threaded cylinder and a ring body that are rotatably and cooperatively connected in sequence. The threaded cylinder is cooperatively installed in the threaded blind hole.

[0017] The number of the annular bosses and the lifting rings is five.

[0018] The number of the threaded through holes and the positioning screws is sixteen.

[0025] (Ⅰ) For the large-volume charge housing with safe remote operation and flipping proposed by the present invention, first, the charge housing filled with liquid-phase material is lifted by a lifting ring.

[0031] The following further elaborates on the specific content of the present invention in conjunction with embodiments. Detailed Embodiment

[0032] It should be noted that the equipment and materials used in the present invention, unless otherwise specified, are all the equipment and materials known in the prior art. For example, the explosives in the present invention are the commonly known explosives in the prior art.

[0033] The present invention connects the spreading pipe, upper end cover, lower end cover, upper circular ring, lower circular ring, upper round rod, lower round rod and arc rod into a whole. This is because when the upper end cover and the lower end cover move independently, the upper end cover moves up and down along the inner surface of the outer shell, and the lower end cover also moves up and down along the inner surface of the outer shell. However, since both the upper end cover and the lower end cover are flat, the axial dimension of the upper end cover and the lower end cover is much smaller than the radial dimension, that is, the aspect ratio is too small. Once deflection occurs during the movement of the upper end cover and the lower end cover, it is very easy to get stuck. For a cylindrical part moving in a cylinder, if the aspect ratio is too small, it is particularly easy to get stuck during the movement. Only when the aspect ratio is close to 1:1 will it not get stuck. Therefore, the upper end cover and the lower end cover are connected into a whole through the upper circular ring, arc rod, lower circular ring and lower round rod of the spreading pipe. Each component of this whole moves at the same speed simultaneously, and the aspect ratio of this whole increases significantly and approaches 1:1, so it will not get stuck during movement, ensuring the normal functioning of the charge housing.

[0034] Following the above technical solution, the following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations made on the basis of the technical solution of this application fall within the protection scope of the present invention.

[0048] As a preferred solution of this embodiment, as Figure 1 shown, the outer diameter of the temporary baffle 10 is smaller than the outer diameter of the outer housing 102.

[0050] In this embodiment, the working process of the remotely operated and safely flipped large-volume charge housing includes the following steps:

[0051] Step 1: Place the cylindrical housing 1 on a horizontal platform so that the central axis of the cylindrical housing 1 is perpendicular to the horizontal plane;

[0052] Step 2: Assemble the lower end cover 5 with the cylindrical housing 1;

[0053] Step 3: Assemble the spreading pipe 4 with the lower end cover 5 and the upper end cover 2;

[0054] Step 4: Assemble the upper end cover 2 with the cylindrical housing 1;

[0055] Step 5: Assemble the lifting ring 16 with the cylindrical housing 1;

[0056] Step 6: Assemble the gas filling pipe 13 with the cylindrical housing 1;

[0057] Step 7: Assemble the temporary baffle 11 with the cylindrical housing 1;

[0058] Step 8: Assemble the positioning screw 105 with the threaded through hole 104;

[0059] Step 9: Pour the liquid into the sealed liquid cavity 15 through the liquid filling port provided on the upper end cover 2;

[0060] Step 10: Pass the lifting rope through the circular ring body 1602 of the lifting ring 16, then hang the lifting rope on the crane, and lift the charge housing by the crane so that the temporary baffle 11 is separated from the ground;

[0061] Step Eleven: Change the posture of the charge housing in this embodiment from the standing posture to the lying posture. Connect one end of the charging pipe 13 with the air charging switch 14 to the high-pressure air pump. Open the air charging switch 14 to allow high-pressure air to enter the high-pressure gas chamber 12. Squeeze the lower end cover 5 through the high-pressure gas. The lower end cover 5 then transfers the pressure to the spreading pipe 4 and the sealed liquid chamber 15. The liquid in the sealed liquid chamber 15 transfers the pressure to the upper end cover 2, causing the spreading pipe 4, the upper end cover 2, the lower end cover 5, the upper circular ring 6, the lower circular ring 7, the upper circular rod 8, the lower circular rod 9, and the arc rod 10 to move upward simultaneously. Since the spreading pipe 4, the upper end cover 2, the lower end cover 5, the upper circular ring 6, the lower circular ring 7, the upper circular rod 8, the lower circular rod 9, and the arc rod 10 are connected as a whole, and all components of this whole move at the same speed, the system centroid of the charge housing in this embodiment gradually moves upward. Under the traction of the lifting rope of the crane, the posture of the charge housing in this embodiment gradually changes from the standing posture to the lying posture as the centroid moves upward. When the central axis of the spreading pipe 4 is parallel to the horizontal plane, close the air charging switch 14 and disconnect the charging pipe 13 from the high-pressure air pump;

[0062] Step Twelve: Change the posture of the charge housing in this embodiment from the lying posture to the standing posture. Open the air charging switch 14 of the charging pipe 13 to release the high-pressure gas in the high-pressure gas chamber 12. Connect one end of the charging pipe 13 with the air charging switch 14 to the vacuum pump. Open the air charging switch 14 to evacuate the high-pressure gas chamber 12, causing the lower end cover 5 to be under negative pressure. The lower end cover 5 then transfers the negative pressure to the spreading pipe 4 and the liquid in the sealed liquid chamber 15. The liquid then transfers the negative pressure to the upper end cover 2, causing the spreading pipe 4, the upper end cover 2, the lower end cover 5, the upper circular ring 6, the lower circular ring 7, the upper circular rod 8, the lower circular rod 9, and the arc rod 10 to move simultaneously in the direction close to the temporary baffle 11. Since the spreading pipe 4, the upper end cover 2, the lower end cover 5, the upper circular ring 6, the lower circular ring 7, the upper circular rod 8, the lower circular rod 9, and the arc rod 10 are connected as a whole, and all components of this whole move at the same speed, the system centroid of the charge housing in this embodiment gradually approaches the temporary baffle 11. Under the traction of the lifting rope of the crane, the posture of the charge housing in this embodiment gradually changes from the lying posture to the standing posture as the centroid approaches the temporary baffle 11. When the central axis of the spreading pipe 4 is perpendicular to the horizontal plane, close the air charging switch 14 and disconnect the charging pipe 13 from the vacuum pump;

[0063] Step Thirteen: Tighten the positioning screw 105. Squeeze the upper surface of the upper end cover 2 through the positioning screw 105 to fix the position of the upper end cover 2, so that the upper end cover 2 and the outer housing 102 can no longer move relative to each other. Remove the temporary baffle 11. At this time, the charge housing in this embodiment completes the preparation before the experiment.
