Description

Technical Field

[0001] The invention relates to the technical field of marine engineering vessels such as launching barges and semi-submersible vessels, and in particular to a load measurement feedback device for launching barges. Background Art

[0002] When launching a newly built or repaired platform or ship on land, a transfer system is needed to transfer the platform or ship from the ground to a launching barge, which will then transport it to a suitable water area. The launching barge will dive to a certain depth to complete the launching of the platform or ship. During the transfer from the ground to the launching barge, the load on the launching barge is constantly changing. The change in load may cause the hull to tilt. At this time, there will be a height difference between the deck of the launching barge and the dock. When the height difference reaches a certain value, it will affect the normal operation of the transfer system, thereby affecting the smooth progress of the launching work. In serious cases, it may cause safety accidents and damage to personnel and property.

[0003] In order to ensure that the transfer work can proceed smoothly, it is necessary to monitor the load conditions on the ship in real time during the transfer process, and feed back the load conditions to the ship's control system in real time. The ship's control system adjusts the ballast water system more accurately based on the feedback signal combined with the four-corner draft gauge to keep the hull as stable as possible, so that the height difference between the launching barge deck and the dock is always kept within a reasonable range. According to the load measurement feedback device and method for launching barges described in patent number CN113418568A, when in use, a single-point support is performed through a guide column. Due to the contact area, it is easily affected by the lateral force and is easily damaged, resulting in errors in the measurement results. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a load measurement feedback device for a launching barge, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a load measurement feedback device for a launching barge, comprising a mounting bracket and a hydraulic cylinder fixed in the inner cavity of the mounting bracket, the inner cavity of the mounting bracket is fixedly connected to a support plate, the top end of the hydraulic cylinder piston rod passes through and extends to the top of the support plate, the top end of the hydraulic cylinder piston rod is sleeved with a movable rod, the bottom of the movable rod is provided with a movable groove adapted to the top end of the hydraulic cylinder piston rod, the top end of the hydraulic cylinder piston rod is slidably connected to a sliding rod, the top end of the sliding rod extends to the inner cavity of the movable groove and is rotatably connected thereto, the surface of the sliding rod is sleeved with a reset spring, The top of the movable rod passes through the top of the mounting bracket and is movably connected thereto. The top of the movable rod is fixedly connected to a receiving plate. The top of the receiving plate is fixedly connected to a hydraulic cylinder. The inner cavity of the hydraulic cylinder is slidably connected to a support rod. The surface of the movable rod is fixedly connected to a hydraulic oil tank. The hydraulic oil tank is connected to the inner cavity of the hydraulic cylinder through a connecting pipe. There are multiple hydraulic cylinders, which are distributed in a circular array on the surface of the receiving plate. When in use, the barge is docked at the dock, and the hull control system on the barge is ready; the product used for this product is transported to the dock by a forklift, and the preparation work is completed; the initial working state of the load measurement feedback device is adjusted;The transfer system starts to work and transfers the platform and ship from the ground to the barge. During this process, the receiving plate on the top of the load measurement feedback device receives the load. First, by judging the slope of the barge contact position, a suitable angle is selected for the receiving plate so that the height difference between the four support rods and the barge contact position is minimized. At this time, the reset spring drives the movable rod to rise, and the angle of the receiving plate is adjusted by rotating the movable rod. At this time, a damping is set between the movable rod and the sliding rod to prevent its own movement, and then it contacts the barge. The lower surface of the barge load arm contacts the four support rods above the receiving plate. At this time, the high-position support rod is first subjected to pressure and moves downward to squeeze the hydraulic oil in the hydraulic cylinder. At this time, the movable rod is squeezed and pressed down to compress the reset spring to move, and then drives the limit plate to move downward and plug into the card slot in the adjustment block to fix the angle of the movable rod to prevent it from deviating. After the section is completed, the alignment is ensured by setting the angle pattern, so that the limit plate can be aligned with the clamping groove of the inner cavity of the adjustment block for limiting. While the angle of the receiving plate can be adjusted quickly, it can play a limiting role after it is lowered to prevent it from swinging left and right and affecting the detection effect. At this time, the low-position support rod is lifted up by the thrust of the hydraulic oil and abuts against the surface of the barge load arm. The four support rods connected by a hydraulic oil tank can support the barge at multiple points, and the force transmission is achieved through hydraulic oil to ensure the uniformity of the supporting force, which is more stable. The multi-point force can prevent the single-point support from being easily affected by the lateral force and easily causing damage. The load is measured in real time and converted into an electrical signal and transmitted to the hull control system on the barge. The control system receives the feedback signal and adjusts the ballast water system in real time in combination with the four-corner draft gauge to keep the barge stable. ;

[0009] As a further solution of the present invention: the surfaces of the movable rod and the adjustment block are provided with angled lines, and the angled lines are provided to ensure the alignment, so that the limit plate can be aligned with the clamping groove in the inner cavity of the adjustment block for limiting.

[0010] As a further solution of the present invention: the inner cavity of the mounting bracket is provided with a detection mechanism connected to the hydraulic cylinder, and the detection mechanism feeds back data by detecting the stroke of the hydraulic cylinder and the internal pressure change.

[0011] As a further solution of the present invention: the hydraulic oil tank is arranged in an annular shape on the surface of the movable rod and is evenly arranged below the four hydraulic cylinders to ensure that the stroke of the hydraulic oil is consistent.

[0012] As a further solution of the present invention: a forklift slot is provided at the bottom of the mounting bracket, the lower half of the forklift slot is configured as a trapezoidal slot which is smaller at the top and larger at the bottom, and the upper half of the forklift slot is configured as a square slot, the inner diameter of the square slot is adapted to the surface size of the forklift fork rod, and when in use, the fork rod of the forklift first enters the trapezoidal slot in the inner cavity of the forklift slot, and then rises upward along the trapezoidal slot when lifted, and then is snapped into the square slot to fork the mounting bracket, which can play a role of limiting while being able to lift quickly, and prevents left and right shaking through the square slot, making position control more precise.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when supporting, the high-position support rod is first subjected to pressure and moves downward to squeeze the hydraulic oil in the hydraulic cylinder, and the low-position support rod is lifted upward by the thrust of the hydraulic oil and abuts against the surface of the barge load arm.
