Description

Technical Field

[0001] The invention relates to a heavy object traction device and a traction construction method thereof, in particular to a traction device and a traction construction method thereof for clamping a thick-diameter steel wire rope to provide a large-tonnage traction force. Background Art

[0002] At present, most wire rope traction equipment requires the use of lifting equipment to open the upper cover plate for lowering and installation when installing the wire rope. The current operating method is: using a set of wire rope traction device, the device includes four mechanisms such as a fixed clamp, a movable clamp, a push jack, and a frame. The clamp adopts an upper and lower cover plate, and the wedge structure is composed of a clamping block and a wedge block. The wedge block is connected to the upper and lower cover plates with a large pin shaft, and the pin shaft and the wedge block and the upper and lower cover plates are transitional fits. During the clamping process, the upper and lower cover plates, the clamping block, the wedge block, and the pin shaft are the main load-bearing parts. The friction is reduced by rolling between the wedge-shaped fitting surfaces. The rolling row is composed of a contact plate, a roller, a retaining frame, etc. The clamping jack and the clamping piece are connected by a connecting seat, a bolt, and a pin shaft, and the connection of each component is a rigid connection; using a set of wire rope traction device, the device includes four mechanisms such as front and rear clamps, a linear winch outer frame, and a traction jack. The clamp outer frame, the clamp clamping part, the fixing part, the clamping block, etc. constitute the clamping wire rope structure, and the clamp fastening device is connected to the clamping part with a through-length screw.

[0003] The shortcomings of the current process are: 1. The wedge block is connected to the upper and lower covers by a large pin shaft, and the pin shaft is a transition fit with the wedge block and the upper and lower covers. The processing accuracy is high, the pin shaft is unevenly stressed, and the upper and lower covers are difficult to open after the structure is deformed by stress, which affects the installation of the wire rope; 2. The wedge-shaped fitting surface adopts rolling, which is a non-standard structural part. The length, width and thickness ratio of the plate are not coordinated. After the heat treatment reaches the designed hardness, it is easy to deform, the cost is high, and the installation is complicated; 3. The upper and lower covers of the clamp are the main load-bearing parts, and the cross-sectional coefficient of the upper and lower covers is high. The weight of a single piece is large, and the equipment stops When the machine is overhauled, it needs to be hoisted with professional lifting equipment, which limits the use environment of the equipment; 4. The clamping jack and the clip are connected by a connecting seat, bolts, and pins. The connections between the components are rigid connections. No elastic compensation device is set, and no effective safety measures are designed for the sudden increase of load, such as the impact of surges during offshore operations; 5. The equipment can only be lubricated once, and the equipment needs to be shut down during construction, which reduces the efficiency of the equipment. In special working conditions, when the equipment cannot be shut down for lubrication, it can only work rigidly, reducing the service life of the equipment.

[0004] Patent authorization notification number CN209719872U "A wire rope type hydraulic jack salvage system for deep-water large-tonnage sunken ships" discloses a wire rope traction device that uses a jack system to clamp the wire rope, which partially solves the above problems, but still has the following shortcomings:

[0005] 1) The frame for installing the jack is a closed structure. Both the front and rear clamps have clamping top brackets. The former occupies the frame space when working, and the latter lengthens the longitudinal length of the rear clamp. The length-to-width ratio of the frame increases, which affects the transportation and storage of the equipment;

[0006] 2) The wedge-shaped fitting surface of the clamp uses a customized non-standard plane bearing, which is difficult to process and the plane bearing plate is easily deformed, affecting the installation accuracy;

[0007] 3) The equipment must be shut down to remove the clamping parts and then add lubricating medium. Under certain working conditions, the equipment cannot be shut down for operation. The equipment has low risk resistance and there is a risk of reducing the service life of the equipment.

[0008] 4) There are no spring components between the clamping jack, the clamp connection seat, and the clip. The three are rigidly connected, lacking safety protection measures for sudden overload, and there is a risk of reducing the service life of the equipment. Summary of the invention

[0025] Another related technical solution is: a traction construction method for clamping a thick diameter steel wire rope, which adopts the traction device for clamping a thick diameter steel wire rope to provide a large tonnage traction force as described in claim 1 for traction construction, characterized in that it comprises the following steps:

[0026] A. On-site assembly of traction device for clamping thick diameter wire rope to provide large tonnage traction force:

[0027] A1: Assemble clamping components I and II:

[0028] Insert the lubricating oil assembly into the groove of the wedge block, pay attention to the installation direction of the oil inlet nozzle, and fix the MGB plate Ⅰ and MGB plate Ⅱ to the wedge block with countersunk hexagonal bolts; fix the fixture connection seat to the front end of the wedge block, and reserve compression margins between the guide bolts Ⅰ, Ⅱ, Ⅲ, Ⅳ and the bonding plate according to the design requirements to complete the installation of the clamping assembly Ⅰ and Ⅱ;

[0029] A2: Assemble the traction device body in the frame body:

[0030] A21: Install the clamping assembly I, clamping assembly II, clamping jack I, and clamping jack II into the movable clamp and fixed clamp;

[0031] A22: The fixed clamp is hoisted into the frame body and fixed with bolts. The clamping jacks Ⅰ and Ⅱ are connected to the frame body with connecting pins Ⅱ and Ⅲ.

[0032] Hang the thrust jacks Ⅰ and Ⅱ into the main frame;

[0033] After assembling the movable clamp, slide rail I and slide rail II, they are hoisted into the main frame. The movable clamp, thrust jack I and thrust jack II are connected with pins. The slide rails I and II are fixed to limit the vertical displacement of the movable clamp.

[0034] A23: Installation of clamped steel strands:

[0035] A231. Start the clamping jacks I and II of the fixed clamp and the movable clamp, drag out the clamping assembly I and the clamping assembly II, remove the connecting plates I, II, III, IV and V, and vertically place the thick-diameter wire rope to be clamped into the fixed clamp and the movable clamp;

[0036] A232. Restore the positions of clamping assembly I, clamping assembly II, connecting plates I, II, III, IV and V, install the movable crossbeam, guide rollers, hydraulic oil circuit, sensor and hydraulic valve group;

[0037] B. Clamping and pulling of thick diameter wire rope:

[0038] B1: Initial stage - fixed clamp holding thick diameter wire rope:

[0039] The pistons of the clamping jacks Ⅰ and Ⅱ of the movable clamp are retracted to the initial position, that is, the pistons are located at the P1 position, the pistons of the clamping jacks Ⅰ and Ⅱ of the fixed clamp are extended to the initial position, that is, the pistons are located at the Q2 position, and the pistons of the thrust jacks Ⅰ and Ⅱ are retracted to the initial position, that is, the pistons are located at the S1 position. At this time, the movable clamp releases the thick diameter wire rope, and the fixed clamp clamps the thick diameter wire rope;

[0040] B2: The fixed clamp continuously clamps the thick diameter wire rope to stabilize the stage:

[0041] The oil pump works, and the piston extension cylinders of the thrust jacks Ⅰ and Ⅱ move from S1 to S2. At this time, the piston extension cylinders of the clamping jacks Ⅰ and Ⅱ of the movable clamp move from P1 to P2, and the piston retraction cylinders of the clamping jacks Ⅰ and Ⅱ of the fixed clamp move from Q2 to Q1. Through the control of the hydraulic oil circuit, at this stage, the piston extension speed of the clamping jacks Ⅰ and Ⅱ of the movable clamp is greater than the piston retraction speed of the clamping jacks Ⅰ and Ⅱ of the fixed clamp, ensuring that there is no interference in the clamping process;

[0042] B3: Movable clamp for holding thick diameter wire rope:

[0043] The pistons of the clamping jacks Ⅰ and Ⅱ of the movable clamp extend and move to the P2 position, the pistons of the clamping jacks Ⅰ and Ⅱ of the fixed clamp retract to the Q1 position, and the pistons of the thrust jacks Ⅰ and Ⅱ extend to the S2 position, completing the alternating looseness and tightness of the clamped thick-diameter steel wire rope; at this time, the movable clamp and the fixed clamp maintain the state, the pistons of the thrust jacks Ⅰ and Ⅱ continue to extend, and the movable clamp clamps the thick-diameter steel wire rope on the slide rails Ⅰ and Ⅱ and slides longitudinally with the pistons of the thrust jacks Ⅰ and Ⅱ;

[0044] B4: The movable clamp continuously clamps the thick diameter wire rope to stabilize the stage:

[0045] The pistons of thrust jack Ⅰ and thrust jack Ⅱ continue to extend to position S3, and the sensor reads the information. At this time, the pistons of clamping jack Ⅰ and clamping jack Ⅱ of the movable clamp begin to shrink, and the pistons of clamping jack Ⅰ and clamping jack Ⅱ of the fixed clamp begin to extend. The pistons of thrust jack Ⅰ and thrust jack Ⅱ continue to extend and move from position S3 to position S4. The pistons of clamping jack Ⅰ and clamping jack Ⅱ of the movable clamp shrink from P 2 to P1, the piston cylinders of the clamping jacks Ⅰ and Ⅱ of the fixed clamp extend from Q1 to Q2; at this time, the movable clamp gradually loosens the thick diameter wire rope, and the fixed clamp gradually clamps the thick diameter wire rope, through the control of the hydraulic oil circuit. At this stage, the piston cylinder retraction speed of the clamping jacks Ⅰ and Ⅱ of the movable clamp is lower than the piston cylinder extension speed of the clamping jacks Ⅰ and Ⅱ of the fixed clamp, ensuring that the clamping process does not interfere;

[0046] B5: The movable clamp completely releases the thick diameter wire rope, and the fixed clamp completely clamps the thick diameter wire rope again:

[0047] The pistons of thrust jacks I and II extend to position S4, which is the stroke of the thrust jacks. The movable clamp completely releases the thick-diameter wire rope, and the fixed clamp completely clamps the thick-diameter wire rope again.

[0048] B6: Return to the initial stage:

[0049] The pistons of the clamping jacks Ⅰ and Ⅱ of the fixed clamper are kept at the Q2 position, the pistons of the clamping jacks Ⅰ and Ⅱ of the movable clamper are kept at the P1 position, and the pistons of the thrust jacks Ⅰ and Ⅱ are retracted from the S4 position to the S1 position without load, and the device returns to the initial position;

[0050] C: Repeat steps B1-B6 to complete the clamping and traction of the thick diameter wire rope by alternately clamping the fixed clamp and the movable clamp.

[0051] Due to the above structure, the present invention "a traction device for clamping a thick-diameter steel wire rope to provide a large-tonnage traction force and a traction construction method thereof" has the following beneficial effects:

[0052] 1. The traction device of the present invention is an intermittent traction device. The jacking jack telescopic cylinder has one stroke, and the fixed clamp and the movable clamp complete the alternate clamping to achieve the traction action; the movable clamp and the fixed clamp used to clamp the thick diameter wire rope 4 adopt the wedge clamping principle, which can effectively clamp thick diameter wire ropes of various specifications, and the traction is stable and effective. By using multiple traction devices of the present invention, the traction system can be jointly operated to provide large tonnage traction (see Fig.11 ), the traction construction process is safe, smooth and reliable.

[0053] 2. The traction device of the present invention has the same structure as the movable clamp of the fixed clamp for clamping the thick diameter steel wire rope, the clamping assembly Ⅰ1-3, and the clamping assembly Ⅱ1-14, and the equipment has good stability and safety performance:

[0054] 1. The clamping assembly Ⅰ1-3 and the clamping assembly Ⅱ are composed of a clamp connecting seat 1-3-1, an MGB plate Ⅰ1-3-2, an MGB plate Ⅱ1-3-4 and a clamp 1-3-5; they include a wedge block 1-3-5-1 and a lubricating oil assembly 1-3-5-2. The lubricating oil assembly is located in a groove in the middle of the wedge block. The lubricating oil assembly includes an oil inlet nozzle, an oil outlet nozzle, and a rigid oil pipe. The internal thread of the oil inlet nozzle is a standard structure. By installing the lubricating oil assembly, the equipment can be flexibly filled with lubricating oil, which can greatly improve the lubrication efficiency, reduce downtime operations, and improve construction efficiency.

[0055] 2. The wedge-shaped fitting surface between the clip and the fixture connection seat is composed of a composite stainless steel plate, MGB plate I, and MGB plate II. The material itself has good anti-corrosion properties, and the structural parts are all standard parts with strong versatility and easy to obtain. Compared with steel plates, the MGB plate has a slightly lower elastic modulus and a compression margin is reserved during installation, which can reduce assembly accuracy and installation accuracy, making installation easy. The MGB plate can effectively reduce the vibration and noise of the equipment. At the same time, in the process of clamping the wire rope, the MGB plate can effectively fit the composite stainless steel plate to reduce the phenomenon of excessive local stress. It has a certain shock absorption effect and improves the stability of the equipment.

[0056] 3. The clamping assembly is equipped with a spring to ensure that when the load suddenly increases in the clamping state, the clamp can still effectively clamp the wire rope, thereby improving the safety performance of the equipment:

[0057] The clamping assembly I and the clamping assembly II of the movable clamp and the fixed clamp of the device of the present invention have the same structure, and are both composed of a clamp connecting seat, an MGB plate I, an MGB plate II and a clamping piece; the clamp connecting seat includes springs I, II, III, and IV, guide bolts I, II, III, and IV, as well as a bonding plate, fork ears I and II; a compression margin is reserved between the bonding plate of the clamp connecting seat and the guide bolt, and the wire rope is in a clamped state. When the load suddenly increases (such as the impact of surge in offshore operations), the clamping assembly continues to move forward. At this time, the spring stretches to release the reserved compression margin between the clamp connecting seat and the clamping piece, and the clamping piece can still effectively clamp the wire rope; and the displacement compensation of the spring can effectively prevent the wire rope from suddenly loosening when the load suddenly increases, thereby improving construction safety; avoiding damage to the oil cylinder of the clamping jack due to the clamping assembly continuing to move forward when the load increases, thereby improving the service life of the equipment.

[0058] 3. Use universal materials and standard structural parts, which are easy to obtain and reduce processing costs.

[0059] Fourth, the traction device of the utility model for clamping thick-diameter steel wire ropes to provide large-tonnage traction force is constructed in a manner in which each component is manufactured in a factory and then assembled on the construction site. It can be assembled according to the requirements of steel wire rope specifications and traction force values, is easy to install, and has strong versatility.
