Description

Technical Field

[0001] The invention belongs to the technical field of underwater bed leveling equipment and relates to an underwater bed leveling machine. Background Art

[0002] At present, the leveling of underwater riprap foundation in China is usually done by divers doing underwater manual leveling and manual water pumping for measurement and acceptance. With the need for large-scale port construction in my country, the use of manual leveling of underwater riprap foundation is greatly restricted, mainly due to the influence of operating personnel and construction conditions, and the quality of foundation leveling is difficult to meet the needs of the project. After the traditional manual leveling is completed, manual water pumping is generally used for confirmation and acceptance. Water pumping is greatly affected by weather and sea conditions, instruments, and human factors, and the measurement and acceptance accuracy is low; manual water pumping can only record water pumping in sequence according to mileage and one point of the section, and the progress is slow.

[0003] When traditional divers are used to level the underwater foundation, the weather and sea conditions have a great impact on the leveling efficiency, the safety risk is high, the quality of the leveling cannot be guaranteed, and the cost is high. After the leveling is completed, manual water pumping is used for acceptance. During the measurement, it will be affected by human factors, weather and waves, instrument errors, etc., resulting in low measurement accuracy, large measurement errors, and slow measurement progress. Manual water pumping measurement can only be performed point by point, and comprehensive regional measurement control cannot be performed. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present invention provides an underwater base bed leveling machine. The technical problem to be solved by the present invention is: how to improve the efficiency of leveling.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] An underwater bed leveling machine comprises a frame and a hollow feed pipe, wherein the frame comprises two oppositely arranged cross beams, and the leveling machine further comprises two oppositely arranged sliding beams, the ends of the sliding beams are movably connected to the cross beams respectively, the feed pipe extends in a vertical direction, the feed pipe is movably connected to the sliding beams, the top and bottom of the feed pipe are open, and cylinders are respectively arranged at the two ends of each cross beam, and each cylinder is slidably connected to a piston rod, and the piston rod extends in a vertical direction.

[0007] When leveling, first place the leveling machine steadily on the base bed that needs to be leveled, adjust the length of the piston rod on the oil cylinder extending out of the cylinder body to make the plane where the frame is located consistent with the horizontal direction, then load the stone into the discharge pipe, and then drop it onto the base bed through the discharge pipe. After the stone reaches the base bed from the discharge pipe, control the lateral and longitudinal movement of the discharge pipe. Make the stone spread on the base bed surface, and scrape the stone flat by moving the sliding beam. During the leveling process, ensure that there is material in the conduit, control the loading speed and quantity, and avoid stone overflow. Compared with simple manual operation, this leveling machine greatly improves the leveling efficiency.

[0008] The sliding beam is driven by a driving source, which includes a first hydraulic motor, a transverse rack and a first transmission rod. Each transverse rack is respectively arranged on a transverse beam and extends along the length direction of the transverse beam. First gears are respectively fixed to the ends of the first transmission rods, and each first gear is respectively meshed with a transverse rack. The first hydraulic motor is arranged on the sliding beam, and the first hydraulic motor drives the first transmission rod to rotate. The first transmission rod moves along the transverse beam while rotating, thereby driving the sliding beam to move, and the discharge pipe on the sliding beam moves accordingly.

[0009] The feeding pipe is driven by driving source 2, which includes a second hydraulic motor, a longitudinal rack and a second transmission rod. Each longitudinal rack is respectively arranged on a sliding beam and extends along the length direction of the sliding beam. Second gears are respectively fixed to the ends of the second transmission rod, and each second gear is respectively meshed with a longitudinal rack. The second hydraulic motor is arranged at the bottom of the feeding pipe. The second hydraulic motor drives the second transmission rod to rotate. The second transmission rod rotates and moves along the sliding beam, thereby driving the feeding pipe to move longitudinally.

[0010] In the above-mentioned underwater base bed leveling machine, the leveling machine also includes a controller, a hydraulic pump and a hydraulic diverter valve, the hydraulic pump is electrically connected to the controller, the first hydraulic motor and the second hydraulic motor are respectively connected to the hydraulic diverter valve, and the hydraulic diverter valve is connected to the hydraulic pump.

[0011] In the above-mentioned underwater bed leveling machine, the first hydraulic motor and the second hydraulic motor are respectively connected to the hydraulic diverter valve through hydraulic pipes.

[0012] In the above-mentioned underwater bed leveling machine, the frame further comprises two oppositely arranged vertical beams, and the end of each vertical beam is respectively fixedly connected to the end of each horizontal beam. In this structure, the horizontal beams and the vertical beams enclose a closed outer frame.

[0013] In the above-mentioned underwater bed leveling machine, the horizontal beam and the vertical beam are made of steel pipes, and the horizontal beam and the vertical beam are provided with a water inlet and an exhaust valve.

[0014] In the above-mentioned underwater bed leveling machine, four floating drums are connected to the frame, and each floating drum is connected to the connection between the horizontal beam and the vertical beam through a soft rope and can float to the surface. Leveling positioning is divided into rough positioning and fine positioning. During rough positioning, GPS instruments are used for positioning according to the position of the bed to be leveled, the position of the barge, and the span of the crane. At the same time, nylon ropes hung on the wire ropes of the lifting leveling machine are used for assistance, so that the leveling machine can land steadily on the bed to be leveled. The four floating drums are tied to the four corner points of the frame by soft ropes of appropriate lengths. After the leveling machine is launched into the water, the floating drums will float to the surface, and the soft ropes are in a strained state. At this time, the floating positions of the four floating drums are the positions where the four corner points of the leveling machine fall on the bed. Then, the position of the floating drums is measured by using a GPS instrument to determine whether the position of the leveling machine is consistent with the position to be leveled. If it does not meet the requirements, data comparison and analysis can be performed, and then the leveling machine can be lifted and adjusted.

[0015] In the above-mentioned underwater bed leveling machine, the leveling machine also includes a feeding pipe, the bottom of which is fixed to the top of the feeding pipe, and a hopper is provided on the top of the feeding pipe. When the feeding pipe is long enough, the feeding hopper will be exposed to the water surface, and the stone can be more conveniently loaded into the feeding pipe through the hopper and the feeding hopper.

[0016] In the above-mentioned underwater bed leveling machine, a prism is provided on the top of the feed pipe. The prism is installed on the top of the feed pipe, that is, the position where the feed pipe is exposed to the water surface, and the prism is used for total station measurement. During precise positioning, the feed pipe of the leveling machine moves to the four corner points of the frame of the leveling machine for elevation adjustment. The surveyor sets up a total station on the shore, measures the elevation of the scale line at the top of the feeding pipe (the elevation of the bottom of the pipe = the measured elevation - the scale height) and the coordinates of the feed pipe, and continuously adjusts the length of the piston rod of the oil cylinder through the control console to achieve the elevation required for construction. After verification, feeding and leveling can be carried out.

[0017] After the bed is leveled, a multi-beam bathymetric system is used for inspection and acceptance. The multi-beam bathymetric system is also called a multi-beam bathymetric instrument, a strip bathymetric instrument or a multi-beam bathymetric sonar. The traditional single-beam bathymetric system can only obtain a seabed depth value vertically below the survey ship each time. The multi-beam bathymetric system can obtain the seabed depth values ​​of multiple measurement points within a strip coverage area, realizing the transition from "point-line" measurement to "line-surface" measurement. The significance of its technological progress is very prominent.

[0018] As a new high-precision seabed topography detection method, multi-beam survey technology adopts wide-angle transmission and multi-channel directional reception to obtain underwater high-density strip-style seabed topography data, which completely refreshes the basic concepts of traditional detection technology, breaks through the limitations of traditional single-beam detection technology, and greatly improves the accuracy, resolution and work efficiency of seabed topography survey.

[0019] Multi-beam scanning is used for sea sweeping, and the error of multi-wave velocity scanning acceptance is 0.1% of the water depth. If the water depth of the base bed is 20 meters, the error of the scanning acceptance instrument is 2cm. The acceptance measurement accuracy is high, and the entire base bed can be measured and accepted. The acceptance range is wide and fully covered. Through the analysis and acceptance of the scanning effect and cross-sectional diagram of the entire base bed, the acceptance measurement standard and accuracy are high, and the situation of the entire base bed is accurately grasped. After leveling is completed, the one-time acceptance rate of the base bed reaches 100%. The subsequent caisson installation does not require divers to handle the base bed, while improving the efficiency and accuracy of the caisson installation.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] 1. The leveling machine has high leveling efficiency. Normally, one shift of divers can level about 100 square meters underwater, while one shift of underwater leveling machine can level more than 190 square meters.

[0022] 2. This leveling machine has high leveling accuracy. It uses a feeding pipe to fully cover the entire base bed with fabric, and the total station tracks and verifies the elevation, thus ensuring the leveling accuracy.

[0023] 3. This leveling machine has a higher degree of adaptability to sea conditions, is relatively less affected by weather, and is safer. Underwater leveling of the leveling machine only involves underwater hooking and unhooking operations by divers, which takes a short time and avoids the problem of underwater manual leveling being an all-weather operation with high safety risks.

[0024] 4. Lower cost. The comprehensive cost of leveling with a leveling machine is lower than the comprehensive cost of manual leveling. BRIEF DESCRIPTION OF THE DRAWINGS
