Description

Ten-ton-level liquid phase material filling shell capable of automatically overturning through mass center position adjustment

Technical Field

The invention belongs to the technical field of liquid phase material filling shells, relates to a ten-ton liquid phase material filling shell, and particularly relates to a ten-ton liquid phase material filling shell capable of automatically overturning through mass center position adjustment.

Background

Liquid phase materials are filled in the explosive water mist dust removal bomb and the fire extinguishing bomb, the liquid phase materials are scattered into the air under the action of explosive driving loading of the scattered explosives, a cloud cluster with a certain space coverage range is formed, and the effect of the explosive water mist dust removal bomb and the fire extinguishing bomb is increased along with the increase of the diameter of the scattered cloud cluster. In order to improve the diameter of cloud cluster formed by scattering liquid-phase materials, the explosion water mist dust removal bomb and the fire extinguishing bomb are generally designed to be thin-wall shell structures, the energy released after the scattering explosive explodes is used for shell breakage as little as possible, the liquid-phase materials are driven to load and do work as much as possible, the scattering speed of the liquid-phase materials is further improved, and the diameter of the scattering cloud cluster is improved. Therefore, the macroscopic structure of the explosion water mist dust removal bomb and the fire extinguishing bomb is a thin-wall shell structure filled with liquid phase materials.

For a thin-walled shell filled with liquid-phase material, the length-diameter ratio of the shell has a greater influence than the form of cloud formed by scattering. Huijinging et al reported in the document "experimental study of the effect of FAE device parameters on fuel throwing and explosion power" (high-pressure physical reports, 6 months 2004, vol.18, p.2, 105): for the cylindrical thin-wall shell filled with the liquid-phase material, when the length-diameter ratio is properly selected, the shape of a cloud formed by scattering explosives is more ideal, the concentration distribution of the cloud is more uniform, the length-diameter ratio is 3-5 through comprehensive investigation, and the size design of the thin-wall shell filled with the liquid-phase material can be selected within the range.

With the development of products related to thin-wall shells filled with liquid-phase materials, the filling volume of the liquid-phase materials is larger and larger, the total weight of the thin-wall shells filled with the liquid-phase materials is increased, and the weight of the products is developed to the ten-ton level at present. The ten-ton class of thin-walled shells filled with liquid phase material had a diameter of about 2 meters and a length of about 8 meters. During transportation, in order to transport stably, the shell adopts a lying posture, and the axis is parallel to the horizontal plane. When liquid phase materials are filled into the thin-wall shell, in order to ensure that the shell is stable and full during filling, the shell adopts a standing posture, and the axis is vertical to the horizontal plane. When the product is used, in order to improve the coverage of scattering cloud clusters, the shell adopts a standing posture, and the axis is vertical to the horizontal plane. Therefore, the thin-walled case filled with the liquid phase material needs to be repeatedly turned over from lying down to standing up when being filled with the liquid, transported, and used.

The turnover of the ten-ton shell cannot be completed by pure manual operation, and can be safely, reliably and efficiently carried out only by corresponding auxiliary assembly mechanical support equipment. Zhangyumei et al reported a multi-degree-of-freedom turnover vehicle in the document "application of the multi-degree-of-freedom turnover vehicle in satellite assembly" (mechanical manufacturing, 8.2018, vol.56, page 89, 648 th) and composed of a push rod, a turnover frame and an adapter, and the adapter is driven to turn over by stretching and swinging of the push rod, so that the adapter can be turned over at 0-90 degrees. The turnover process of the turnover vehicle to the shell is as follows: the shell is fixed on the turnover vehicle, the outer wall of the shell is connected with the turnover vehicle through a plurality of points, and turnover torque is applied to the shell through the turnover vehicle, so that the shell is subjected to spatial turnover movement, and finally turnover work is finished.

However, when the turnover vehicle is used for turning over a thin-wall shell filled with liquid phase materials in ten-ton class, the following problems occur: when the turnover vehicle finishes the space turnover work of the shell, the turnover vehicle can only ensure that the shell is turned to a required angle, the speed of the turnover process of the shell cannot be accurately controlled, the speed of the shell at the beginning and the end stages of turnover has large sudden change, the shell has the weight up to ten-ton level, the sudden change of the speed in the turnover process can bring great inertial load, the turnover vehicle and the shell are only fixedly connected through a plurality of points, the great inertial load acts on the points, the force borne by each point is great, the shell is a thin-wall shell, the external acting force is too great, the strength of the shell is insufficient and damaged, the leakage of the internal liquid-phase material is further caused, and the failure of the thin-wall shell filled with the liquid-phase material is caused.

Through the experiment discovery, upper end cover 2 is at the inside in-process that removes repeatedly of casing 3, when thickness is than littleer, card owner's phenomenon appears easily, in case card owner, the extrusion force that is bigger again also can't make its continuation motion, and the too big extrusion force can act on casing 3, breaks casing 3 crowded, leads to the failure. And when the ratio of the axial length of the second outer cylindrical surface of the upper end cover 2 to the diameter of the second circular plate of the upper end cover 2 is not lower than 1: when 10, the thickness of the upper end cover 2 is enough, and the problem of jamming does not occur when the upper end cover 2 moves repeatedly in the shell 3.

The weight of the upper end cover 2 is increased along with the increase of the thickness, the total weight of the upper end cover 2 is 10 tons for filling the shell with liquid materials, the difficulty in the shell overturning process is that the total weight is too large, the overturning inertia is large, the pressure born by the shell is too large, the shell is easy to damage, and the weight of the upper end cover 2 is too large, so that only negative effects can be generated. Therefore, the lower the thickness of the upper end cap 2, the better. According to the actual measurement experiment, when the ratio of the axial length of the second outer cylindrical surface of the upper end cover 2 to the diameter of the second circular plate of the upper end cover 2 is not more than 1: 9, the weight of the upper end cap 2 is less than 4% of the total weight, and it is considered that the weight of the upper end cap not exceeding 4% is within an acceptable range, and therefore, the ratio of the axial length of the second outer cylindrical surface of the upper end cap 2 to the diameter of the second circular plate of the upper end cap 2 is not more than 1: 9.

Therefore, the ratio of the axial length of the second outer cylindrical surface of the upper end cap 2 to the second circular plate diameter of the upper end cap 2 is 1: 9-10;

in this embodiment, the ratio of the axial length of the second outer cylindrical surface of the upper end cap 2 to the diameter of the second circular plate of the upper end cap 2 is 1: 9.

the same design of the lower end cover 4 is that the ratio of the axial length of the fourth outer cylindrical surface of the lower end cover 4 to the diameter of the fourth circular plate of the lower end cover 4 is 1: 9-10;

in this embodiment, the ratio of the axial length of the fourth outer cylindrical surface of the lower end cap 4 to the diameter of the fourth circular plate of the lower end cap 4 is 1: 9.

the second upper end circular plane of the upper end cover 2 is parallel to the downward concentric circular ring surface of the third upper end of the shell 3, the distance between the second upper end circular plane of the upper end cover 2 and the downward concentric circular ring surface of the third upper end of the shell 3 is a first distance, the distance between the plane where the axes of the two third threaded blind holes of the shell 3 are located and the centroid of the system is a second distance, the first distance and the second distance are the same, and the fourth lower end circular plane of the lower end cover 4 is in contact with the upward concentric circular ring surface of the third lower end of the shell 3.

Regarding the distance between the axial lines of the two third threaded blind holes of the shell 3 and the lower end of the mass center of the system, the following two aspects are mainly considered, namely, the axial lines are not too long, so that the system is in an ineffective length when the overturning process is completed through the mass center adjustment, the mass center offset is too large, the size to be adjusted is too large, the part of the size is not filled with liquid phase materials and is in an ineffective length, the ineffective length is not too large, and the ineffective length cannot be too short.

Experiments show that when the plane where the axes of the two third threaded blind holes of the shell 3 are located is not less than 120mm at the lower end of the mass center of the system, the mass center offset is sufficient, the mass center is slightly adjusted in the process of turning the system through the mass center adjustment, the rotation angle of the system in the air is small, the generated angular velocity and angular acceleration are small, and the safety requirement is met within a controllable range. When the plane of the axes of the two third threaded blind holes of the shell 3 is positioned at the lower end of the mass center of the system of the invention and is not more than 140mm, the heart offset is not excessively large, the size needing to be adjusted is not excessively large, the invalid length is not more than 2 percent of the total length, and the invalid length is considered to be within an acceptable range.

Therefore, the plane of the axes of the two third threaded blind holes of the shell 3 is 120-140 mm below the mass center of the system;

in this embodiment, the plane of the axes of the two third threaded blind holes of the housing 3 is located at the lower end 120 of the center of mass of the system of the present invention.

Regarding the ratio of the axial distance from the upper end surface of the third annular boss of the housing 3 to the third threaded blind hole of the housing 3 to the nominal diameter of the third threaded blind hole of the housing 3, the ratio of the axial distance from the lower end surface of the third annular boss of the housing 3 to the third threaded blind hole of the housing 3 to the nominal diameter of the third threaded blind hole of the housing 3, mainly consider 2 aspects as follows:

It should not be too small, resulting in insufficient strength, when the system of the invention is suspended by the suspension ring 5, the entire weight is applied to the suspension ring 5, and the suspension ring 5 applies all the weight to the third annular projection of the housing 3, and if the size is too small, a fracture will occur from the third annular projection of the housing 3, resulting in failure of the system. Experiments show that when the ratio of the axial distance from the upper end face of the third annular boss of the shell 3 to the third threaded blind hole of the shell 3 to the nominal diameter of the third threaded blind hole of the shell 3 is not lower than 1.4, and the ratio of the axial distance from the lower end face of the third annular boss of the shell 3 to the third threaded blind hole of the shell 3 to the nominal diameter of the third threaded blind hole of the shell 3 is not lower than 1.1, the strength of the third annular boss of the shell 3 is sufficient.

The size of the third annular boss of the shell 3 is too large, so that the cloud cluster formed after the liquid material is scattered is layered due to the fact that the size of the third annular boss of the shell 3 is too large, the third annular boss of the shell 3 is equivalent to a reinforcing rib, when the third annular boss of the shell 3 is small, the influence on the scattered cloud cluster is not large, and the cloud cluster can be connected together in the subsequent diffusion process. When the size of the third annular boss of the shell 3 is larger, the influence on the cloud cluster throwing is overlarge, the cloud clusters cannot be connected together in the subsequent diffusion process, a fault is formed, and the using effect is influenced. Experiments show that when the ratio of the distance from the upper end face of the third annular boss of the shell 3 to the axis of the third threaded blind hole of the shell 3 to the nominal diameter of the third threaded blind hole of the shell 3 is not more than 1.6, and the ratio of the distance from the lower end face of the third annular boss of the shell 3 to the axis of the third threaded blind hole of the shell 3 to the nominal diameter of the third threaded blind hole of the shell 3 is not more than 1.3, the influence on cloud scattering is not large, and the cloud clusters can be connected together in the subsequent diffusion process.

Therefore, the distance from the upper end surface of the third annular boss of the shell 3 to the axis of the third threaded blind hole of the shell 3 is 1.4-1.6 times of the nominal diameter of the third threaded blind hole of the shell 3, and the distance from the lower end surface of the third annular boss of the shell 3 to the axis of the third threaded blind hole of the shell 3 is 1.1-1.3 of the nominal diameter of the third threaded blind hole of the shell 3.

In this embodiment, the distance from the upper end surface of the third annular boss of the housing 3 to the axis of the third threaded blind hole of the housing 3 is 1.4 times of the nominal diameter of the third threaded blind hole of the housing 3, and the distance from the lower end surface of the third annular boss of the housing 3 to the axis of the third threaded blind hole of the housing 3 is 1.1 of the nominal diameter of the third threaded blind hole of the housing 3.

The axes of the two third threaded blind holes of the housing 3 are located on the same horizontal plane, and about the included angle between the axes of the two third threaded blind holes of the housing 3, the following 3 aspects are mainly considered: rotation sensitivity, initial hoisting stability and hoisting capacity.

The rotation sensitivity is the sensitivity degree of the system for spatial rotation after the mass center of the system is deviated, when the rotation sensitivity is poor, after the mass center of the system is deviated, because the connecting line of the mass center of the system and the two third threaded blind holes is closer in the vertical direction, the projections in the vertical direction are almost overlapped, and after the mass center is changed, the system is rotated without an eccentric force, at the moment, the system is in a destabilization state, and once the system is rotated, the system rotates at a high speed and a high angle, which is not in line with the low-speed rotation principle of the invention. When the rotation sensitivity is good, the connection line of the mass center of the system and the two third threaded blind holes has a certain distance in the vertical direction, and after the mass center of the system is shifted, the weight is multiplied by the distance of the connection line of the mass center of the system and the two third threaded blind holes in the vertical direction, so that the system rotates in space along with the change of the mass center in order to ensure that the system rotates moment, and the instability state is avoided. The rotational sensitivity was divided into 3 criteria by actual testing, and 3 scores. The rotation is very sensitive: 10 minutes; the rotation is occasionally sensitive: 3 min; the rotation is very insensitive: -3 points.

The initial hoisting stability is the stability degree of the system when the system is initially hoisted by a crane. The system is rotated by an angle compared with the posture before hoisting after the initial hoisting with a crane. Because the crane lifts the system, the posture of the system is correspondingly rotated under the action of gravity, and the smaller the rotation angle is, the better the rotation angle is. Because the lifting process does not need the follow-up use process, the rotating speed can be accurately controlled, the lifting process belongs to a simple rough process, the rotating angle is reduced as small as possible, the shell only bears upward force to move upwards, the space posture is rotated as little as possible, the rotating angular speed and the angular acceleration are small, and the shell safety can be guaranteed. When the initial hoisting stability is good, the vertical distance between the center of mass of the shell and the connecting line of the 2 hoisting rings 5 is small, the hoisting system rotates slightly, the center of mass of the shell can be overlapped with the vertical direction of the connecting line of the 2 hoisting rings 5, at the moment, the system is stable, the angular velocity and the angular acceleration are small in the process of slight rotation, and no danger occurs. When the initial hoisting stability is poor, the vertical distance between the centroid of the shell and the connecting line of the 2 hoisting rings 5 is large, the hoisting device needs to rotate by a large angle, the centroid of the shell can be vertically overlapped with the connecting line of the 2 hoisting rings 5, at the moment, the system can be stable, and in the process of rotating by a large angle, the angular velocity and the angular acceleration are large, so that danger can occur. Through practical tests, the initial hoisting safety is divided into 3 standards and 3 scores. The rotation angle does not exceed 3 °: 10 minutes; the rotation angle is 3-10 degrees: 5 min; the rotation angle exceeds 10 °: and 0 point.

The lifting capacity is the capacity of the weight of the system of the invention that 2 lifting rings 5 can lift. Because 2 rings 5 are at a certain angle, when hoisting, 2 rings 5 bear both shearing force and bending moment, and bear pulling force, the stress state is very complicated, and under the multi-stress state, the gravity of the system of the invention which can be borne by 2 rings 5 is lower than the actual pure shearing resistance of 2 rings. When the hoisting capacity is good due to the structure of the hoisting device, the force borne by the 2 hoisting rings 5 is mainly shear force, and the rotating bending moment and the tensile force are both small, so that the weight of the hoisting device capable of hoisting by the 2 hoisting rings 5 is close to the actual pure shear resistance of the 2 hoisting rings 5. When the hoisting capacity is poor due to the structure of the hoisting device, the force borne by the 2 hoisting rings 5 is the mixed action of shearing force, rotating bending moment and pulling force, and the ultimate strength of the parent material of the 2 hoisting rings 5 can be easily achieved, at this time, the weight of the hoisting device capable of hoisting by the 2 hoisting rings 5 is very low and is only a very small part of the actual pure shearing resistance of the 2 hoisting rings 5, and at this time, danger is easily caused during hoisting. Through practical test, the lifting capacity is divided into 3 standards and 3 scores. The hoisting weight is more than 80% of the actual pure shear resistance: 10 minutes; the hoisting weight is 80% -60% of the actual pure shear resistance: 6 minutes; the weight per hook is 60% or less of the actual pure shear resistance: and 2 minutes.

The included angle of the axes of the two third threaded blind holes of the shell 3 is divided into the following intervals: 179-180 degrees, 178-179 degrees, 177-178 degrees, 176-177 degrees, 175-176 degrees, 174-175 degrees, 173-174 degrees, 172-173 degrees, 171-172 degrees and 170-171 degrees.

The included angles of the axes of the two third threaded blind holes of the shell 3 in the above intervals are respectively tested and evaluated according to the above three standards, and the obtained scores are as follows:

the included angle of the axes of the two third threaded blind holes of the housing 3	Sensitivity to rotation	Initial hoisting safety	Lifting capacity	Total score
					179°～180°	-3	10	10	17
178°～179°	3	10	10	23
					177°～178°	10	10	10	30
176°～177°	10	10	10	30
					175°～176°	10	5	10	25
174°～175°	10	5	6	21
					173°～174°	10	5	6	21
172°～173°	10	5	6	21
					171°～172°	10	0	6	16
170°～171°	10	0	2	12

Experiments show that when the included angle of the axes of the two third threaded blind holes of the shell 3 is 176-178 degrees, the obtained score is the highest, and 30 scores are obtained.

Therefore, the included angle of the axes of the two third threaded blind holes of the housing 3 is 176-178 °.

In this embodiment, the included angle between the axes of the two third threaded blind holes of the housing 3 is 176 °.
