Detailed Description
The invention provides an automatic unhooking device for hanging and placing bearing of marine operation equipment, which aims at the conditions of high working risk coefficient and large misoperation of personnel in the severe environment in the prior marine operation, and aims at facilitating connection of a deep-sea towing cable and an underwater sonar system. The bearing unhooking device can be commonly used with most land unhooking devices.
As shown in fig. 1 and 2, the automatic unhooking device mainly consists of a cylinder 1, a load-bearing bar 11, and a stabilizing mechanism for stabilizing the load-bearing bar 11. Wherein the load-bearing bar 11 and the stabilizing mechanism constitute a unhooking mechanism.
As shown in fig. 3, the cylinder 1 mainly comprises a cylindrical thin-walled cylinder, a semicircular ring-shaped hanging ring 16 and at least two rectangular long and thin through holes 17. The lifting ring 16 is positioned at the top of the cylinder body 1, and as a lifting part, the cylinder body 1 is fixedly connected with the lower part of the main body of the lifting ring 16 in a welding mode. The thin-walled cylinder is a hollow cylinder. The left side and the right side of the cylinder body are symmetrically provided with slender rectangular through holes 17. The inside of the cylinder 1 is vertically communicated for passing through the bearing rod 11, and the through hole 17 of the cylinder is for passing through the ratchet wheel 5.
The cylinder 1 serves as a main body frame, and in this embodiment, has a preliminary overall size of a thin-walled cylinder having an outer diameter of 100mm, an inner diameter of 80mm, and a height of 250 mm. As a load-bearing structure, the thickness of the cylinder 1 needs to be properly increased along with the increase of the cylinder diameter to increase the strength of the cylinder 1, so as to prevent the cylinder 1 from being severely deformed due to stretching when fully loaded. By the finite element analysis of Solidworks, the stress, displacement, deformation and other diagrams show that the original cylinder wall with the diameter of 10mm can be severely deformed due to overlarge stress. The deformation degree of the cylinder body 1 is obviously reduced after the wall thickness is increased to 20mm, but obvious stress concentration still exists in the welding seam part with the ear block 2 (shown in fig. 6), and the specific reinforcement improvement mode needs to refer to the stress, deformation and displacement image analysis of statics analysis. In practical applications, the size and thickness of the cylinder 1 are not limited to the data of the present embodiment, and specific data may vary according to the structure and strength of the cylinder 1.
As shown in fig. 5, the load-bearing bar 11 includes a stopper 12, a snap ring 14, and a bar body 13 connecting the stopper 12 and the snap ring 14. The limiting portion 12 is provided with an axial positioning groove. The limit part 12 of the bearing rod 11 enters the cylinder body 1 through the lower end of the thin-walled cylinder and is meshed with the clamping groove of the ratchet wheel 5 penetrating through the through hole 17. The cross section is set to be perpendicular to the cross section of the rod body 13, and the cross section of the limiting part 12 is small at the top and large at the bottom. That is, the area of the cross section of the stopper 12 away from the rod body 13 is smaller than the area of the cross section of the stopper 12 close to the rod body 13. Also, the cross-sectional area of the rod body 13 is smaller than that of the stopper 12 in contact with the rod body 13. Therefore, the cross section of the limiting part 12 is circular, the axial section of the limiting part 12 is isosceles trapezoid, and the diameter of the largest cross section of the limiting part 12 is smaller than or equal to the inner diameter of the cylinder 1. In practical application, the shaft cross-section shape of the limiting part is not necessarily isosceles trapezoid, and the cross-section shape is not necessarily circular.
The fan-shaped edge formed by expanding the side surface of the limit part 12 is set as a bus. The included angle formed by the bus and the bottom surface of the limiting part 12 is the corner of the limiting part 12. The corners of the limiting parts 12 are the same as the opening angles of the clamping grooves of the ratchet wheel 5. Therefore, the edge of the stopper 12 can engage with the engaging groove of the ratchet 5. After engagement, the ratchet wheel 5 can not only limit the up-and-down movement of the bearing rod 11, but also limit the displacement of the bearing rod 11 in the horizontal direction, so as to prevent the bearing rod 11 from violently striking the cylinder wall. The design of the annular inclined plane of the limiting part 12 not only can achieve the purpose of limiting up-and-down displacement, but also can limit the limiting part 12 in the annular inclined plane by utilizing the component force of the load on the inclined plane, and the larger the load mass is, the larger the transverse limiting force is.
As shown in fig. 1 and 2, a stabilizing mechanism is disposed at each through hole 17. One stabilizing mechanism comprises a ratchet wheel 5, a pawl 4, two ear pieces 2 and a control handle 3. The ratchet wheel 5 is connected with the first holes 8 of the two ear blocks 2 through a first connecting piece, and the pawl 4 is connected with the second holes 9 of the two ear blocks and the control handle 3 through a second connecting component. The first connecting piece is a bolt, and the second connecting component is a square column head.
The outer edge of the ratchet wheel 5 is provided with a clamping groove, and the inner edge of the ratchet wheel 5 is provided with a gear. In the present embodiment, the ratchet 5 is a sector ratchet 5, and is preferably an NY-type inner ratchet 5. Each through hole 17 passes through one ratchet wheel 5, and the edge of the limiting part 12 is meshed with the clamping grooves of at least two ratchet wheels 5. As shown in fig. 6, the two sides of the ratchet wheel 5 are provided with the ear blocks 2, and are connected with the ear blocks 2 through the first holes 8 of the ear blocks 2, so that the rotation movement within a limit range can be performed around the mounting shaft on the ear blocks 2, and the limit range is that the clamping groove is not separated from the edge of the limit part 12. To ensure fluency in movement of the ratchet 5, it is desirable that the fit between the ratchet 5 and the ear piece 2 be an interference fit. Ensure that the two have sufficient space without severe friction. The limit range of rotation of the ratchet wheel 5 is 0-51.11 degrees.
The pawl 4 is meshed with a gear of the ratchet wheel 5, and the meshing gear stages are the same. The pawl 4 is connected to the tab 2 via a key 6, a pawl shaft 7 and via a second hole 9 in the tab 2. The limit of rotation of the pawl 4 is 0-5 deg..
As shown in fig. 6, the ear pieces 2 are rectangular with rounded corners, and the two ear pieces 2 are fixed to both sides of the through hole 17 by welding, respectively. The welding lines of the lug 2 and the cylinder 1 are all straight lines, and the welding can be performed by adopting a robot, so that the welding depth is required to be increased as much as possible under the condition that the inner wall of the cylinder is not obviously influenced (welded through), and the connecting area is increased, so that the connecting strength is improved. The welding of the ear piece 2 and the cylinder 1 has slightly higher requirements for position accuracy than the welding of the upper and lower hanging rings 16. During welding, the pair of left and right ear blocks 2 can be fixed through the clamp, welding is completed, cooling is performed, the clamp is not dismounted, and the clamp stands for one day, so that stress is released. After the clamp is disassembled, the position is measured, the distance between the two ear blocks 2 can be upwards or downwards, and if the distance between the two ear blocks 2 is smaller, small-amplitude correction can be performed through breaking or polishing. And ensures that no burrs or welding slag in the notch of the barrel 1 affect the movement of the ratchet wheel 5.
As shown in fig. 1, 2 and 4, the upper portion of the control knob 3 is connected to the outer wall of the cylinder 1, and the area of the contact surface at the connection is variable. With the rotation of the control handle 3, the contact area between the control handle 3 and the outer wall of the cylinder body 1 is changed from large to small or from small to large. Two circular holes are arranged on two sides of the semi-concave circle of the upper part of the control handle 3. The two ends of the square column head of the second connecting component are provided with top thread holes. A plurality of counter sunk holes 18 are arranged at the round corners of the side surface of the lower part of the control handle 3. The control handle 3 is connected to the spacer 15 by means of a plurality of countersunk screws 10. The cushion block 15 is connected with one end of a square column head through a jackscrew, and the square column head penetrates through the lug blocks 2 and the pawl 4, so that the connection of the control handle 3, the two lug blocks 2 and the pawl 4 is realized.
In summary, the detacher device of the present invention has two states: non-limit state, limit state. In the non-limiting state, the bearing rod 11 does not enter the cylinder 1, or the bearing rod 11 is not in contact with the ratchet wheel 5. At this time, the upper part of the control handle 3 is attached to the outer wall of the cylinder 1, and the contact surface area between the two is the largest.
In the limit state, the bearing rod 11 enters the cylinder body 1 from bottom to top, the bearing rod 11 is in contact with the ratchet wheel 5, the edge of the limit part 12 of the bearing rod is meshed with the clamping groove of the ratchet wheel 5, the limit part 12 of the bearing rod is limited by the ratchet wheel 5 at least two positions, the ratchet wheel 5 can not only limit the up-and-down movement of the bearing rod 11, but also limit the displacement of the bearing rod 11 in the horizontal direction, and the violent collision of the bearing rod 11 and the cylinder wall is prevented. At this time, the control knob 3 is separated from the outer wall of the cylinder 1, and the contact surface area between the control knob and the outer wall is reduced. Wherein the control knob 3 controls the rotation of the pawl 4 such that the pawl 4 rotates within a defined range of 0 to 5 deg.. In the process of upward movement of the bearing rod 11, the rotation angle of the ratchet wheel 5 is continuously increased, and under the condition that the ratchet wheel 5 and the bearing rod 11 are always meshed, the limit range of rotation of the ratchet wheel 5 is 0-51.11 degrees. Therefore, when unhooking, the control handle 3 and the ratchet wheel 5 and the pawl 4 are matched to control the axial positioning movement, and the danger of accidental unhooking can not occur within the limit guarantee range.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
