Description

Technical Field

[0001] This utility model relates to the technical field of laying boat equipment, specifically a force-bearing device for laying boat rollers. Background Technology

[0002] The laying rollers on the laying vessel play a crucial role in engineering projects. They not only collect and organize the geotextile soft sheet and other base fabrics, and slowly unroll and lay them according to construction requirements, but also, with the help of the drive system, flexibly adjust the rotation speed and apply tension according to the construction environment such as water flow and vessel speed, ensuring that the sheet is flat and closely adheres to the seabed. At the same time, the laying rollers can accurately guide the sheet to unfold in a predetermined direction through axial positioning and guiding mechanisms, improving the splicing accuracy of adjacent sheets, and effectively reducing damage to the sheet caused by friction and other factors during the laying process.

[0003] The laying roller force-bearing device of the laying vessel is the core component that ensures its normal operation. It mainly includes a drum drive device, which controls the unwinding speed, applies tension, and achieves braking through the coordinated control of drive motor, reducer, etc.; a support device, which bears the weight of the roller and the laying body, maintains the stability of the roller, and prevents deformation; a tensioning device, such as a spring or hydraulic tensioner, can adjust the tension of the laying body and maintain a suitable tension; a guiding device, with components such as guide wheels and guide plates, guides the laying body to be laid in a predetermined direction to avoid deviation; and a friction device, through structures such as friction rollers, increases the friction between the laying body and the roller to prevent slippage.

[0004] The rollers on existing paving vessels have a fixed and non-adjustable length. When facing different paving operations, the rollers cannot dynamically adapt to the actual working scenario, resulting in reduced construction efficiency during the paving process. Therefore, a force-bearing device for the paving rollers on paving vessels is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a force-bearing device for the laying rollers of a laying vessel. By setting a second roller that can slide inside the first roller and a fixed seat that can drive the two rollers to slide, the entire roller can be adaptively adjusted to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A force-bearing device for laying rollers on a laying vessel includes a base, on the upper part of which a first roller and a second roller are slidably mounted. The first roller has a cavity for mounting the second roller inside, and the second roller is slidably mounted in the middle of the cavity. A limiting ring for limiting the movement of the second roller is installed inside the cavity on the outer arc surface of the second roller.

[0008] Both the first and second rollers are equipped with a fixed seat on one side to limit their movement. The base has a groove for mounting the fixed seat in the middle. The bottom of both sets of fixed seats is equipped with a slider that works in conjunction with the groove.

[0009] Preferably, a servo motor for driving a bidirectional lead screw is embedded inside the base, and the bidirectional lead screw is installed inside the slide groove.

[0010] Preferably, the two ends of the bidirectional lead screw are respectively provided with a left-hand threaded section and a right-hand threaded section, and the two sets of sliders are respectively threadedly connected to the left-hand threaded section and the right-hand threaded section.

[0011] Preferably, the upper surface of the base is provided with several sets of positioning holes for positioning the fixed seat, and a positioning pin is installed through the upper part of each set of sliders to cooperate with the positioning holes for positioning.

[0012] Preferably, each of the two sets of fixed seats is equipped with an independently controlled hydraulic motor on one side. The two sets of hydraulic motors have different displacements, and the two sets of hydraulic motors drive the first roller and the second roller to rotate respectively.

[0013] Preferably, both the first roller and the second roller have several sets of buffer protrusions evenly distributed circumferentially on their outer arc surfaces, and the cross-section of the buffer protrusions is semi-circular, with several sets of anti-slip textures on their outer arc surfaces.

[0014] Preferably, the sidewall of the cavity is fitted with an annular gasket to buffer the limiting ring, and the inner sidewall of the annular gasket is in contact with the outer sidewall of the limiting ring.

[0015] Preferably, the base has several sets of threaded holes in the middle for fixing the base, and each set of threaded holes is fitted with bolts that connect the base and the hull.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the length of the roller needs to be adjusted, the driving component moves the slider linearly along the groove, and the fixed seat, rigidly connected to the slider, synchronously drives the second roller to extend and retract within the first roller's cavity, thus achieving stepless adjustment of the roller's working length. The slider moves the fixed seat, which in turn moves the roller, allowing the laying vessel to quickly adjust the effective length of the roller according to operational requirements. This adjustable roller device significantly improves the laying vessel's functional adaptability and operational coverage, greatly enhancing the overall efficiency of the equipment while ensuring construction accuracy.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a force-bearing device for the laying rollers of a laying boat, such as... Figures 1-5As shown, the system includes a base 1, on which a first roller 2 and a second roller 3 are slidably mounted. The first roller 2 has a cavity 4 for mounting the second roller 3, which is slidably mounted in the center of the cavity 4. A limiting ring 5 is installed inside the cavity 4 on the outer arc surface of the second roller 3 to limit its movement. The base 1 is the fundamental support structure for the entire laying vessel's roller force-bearing device, providing a platform for the first roller 2 and the second roller 3. It can withstand the pressure and forces from the first roller 2, the second roller 3, and those generated during actual use due to the rollers bearing heavy loads or being subjected to external forces, ensuring the stability of the entire device during operation and preventing tilting or displacement due to uneven force distribution or insufficient support. The cavity 4 inside the first roller 2 provides installation space for the second roller 3, allowing it to slide within the cavity and share and transmit various forces during the laying operation while adjusting its length. The limiting ring 5 limits the movement of the second roller 3. During the process of the second roller 3 sliding in the cavity 4, the limiting ring 5 can prevent the second roller 3 from sliding out of the cavity 4, ensuring that the second roller 3 always slides within the predetermined track and range, thus ensuring the structural integrity and operational safety of the device.

[0026] Both the first roller 2 and the second roller 3 have a fixed seat 6 installed on one side to limit their movement. The base 1 has a groove 7 in the middle for installing the fixed seat 6. The bottom of both sets of fixed seats 6 is equipped with a slider 8 that works with the groove 7. The fixed seat 6 can limit the excessive movement of the roller in the horizontal direction, prevent the first roller 2 and the second roller 3 from deviating or misaligning during sliding, and ensure that the roller always runs on the predetermined working track. In addition, the fixed seat 6 can also provide a certain support force for the roller, share some of the external force borne by the roller during operation, enhance the stability of the roller under force, and reduce the possibility of damage to the roller due to uneven force. The groove 7 defines the direction and range of movement of the fixed seat 6, so that the fixed seat 6 can slide along a specific path on the base 1, thereby driving the first roller 2 and the second roller 3 connected to it to move in a regular manner. The slider 8 works with the groove 7 and its main function is to realize the smooth sliding of the fixed seat 6 in the groove 7, thereby facilitating the position adjustment of the first roller 2 and the second roller 3 according to actual working needs.

[0027] Preferably, a servo motor 9 for driving the bidirectional lead screw 10 is embedded inside the base 1. The bidirectional lead screw 10 is installed inside the slide groove 7. In the force-bearing device of the laying rollers on the laying vessel, the high-precision operation of the servo motor 9 ensures the driving accuracy of the bidirectional lead screw 10, thereby achieving precise control of the position of the first roller 2 and the second roller 3, meeting the diverse needs of roller position adjustment in different laying operations. The bidirectional lead screw 10 can perform forward and reverse rotation under the drive of the servo motor 9. When the bidirectional lead screw 10 rotates, it cooperates with the slider 8 at the bottom of the fixed seat 6 to convert the rotational motion of the lead screw into the linear motion of the fixed seat 6 within the slide groove 7.

[0028] The servo motor 9 can be a Panasonic MINAS A6 series, which uses an absolute encoder, has a repeatability of ±0.01mm, supports a wide speed range of 0~3000r / min, and matches the fine-tuning requirements of the roller position in the laying vessel operation. Its IP67 protection rating can adapt to the humid environment of the hull, and the built-in vibration suppression function can reduce the impact of start-up and shutdown and extend the service life of transmission components.

[0029] Preferably, the two ends of the bidirectional lead screw 10 are respectively provided with a left-hand threaded section and a right-hand threaded section. The two sets of sliders 8 are threadedly connected to the left-hand threaded section and the right-hand threaded section, respectively. When the bidirectional lead screw 10 rotates, the sliders 8 connected to the left-hand threaded section and the right-hand threaded section will have different directions of movement. This design allows the two sliders 8 to move closer or further away in a symmetrical and synchronous manner when the lead screw rotates, thereby driving the first roller 2 and the second roller 3 connected to it to move relative to each other or move synchronously.

[0030] Furthermore, the upper surface of the base 1 is provided with several sets of positioning holes 11 for positioning the fixed seat 6. Each set of sliders 8 has a positioning pin 12 installed through the upper part to cooperate with the positioning hole 11 for positioning. When the fixed seat 6 drives the roller to adjust to the appropriate position, the positioning hole 11 can cooperate with the positioning pin 12 to firmly fix the fixed seat 6 on the base 1, preventing the fixed seat 6 from being displaced due to external impact, vibration or load change during the operation of the device, ensuring that the roller maintains a stable working state during operation, thereby improving the accuracy and reliability of the laying operation.

[0031] Furthermore, each of the two sets of fixed bases 6 is equipped with an independently controlled hydraulic motor 13. The two sets of hydraulic motors 13 have different displacements and drive the first roller 2 and the second roller 3 to rotate respectively. Driven by pressurized oil provided by the hydraulic system, the hydraulic motors 13 convert hydraulic energy into mechanical energy, outputting rotational power to drive the rollers. The independent control feature allows each hydraulic motor 13 to be adjusted individually according to actual operational needs. Since the two sets of rollers have different radii, the two sets of hydraulic motors with different displacements can be adjusted to ensure that the laid items reach a synchronized speed, guaranteeing smooth laying. The smaller displacement hydraulic motor 13 has a higher speed response capability, enabling it to quickly adjust its output speed and drive the smaller radius roller to operate at a suitable speed; while the larger displacement hydraulic motor, while ensuring the torque required by the larger radius roller, rationally controls its speed to match the linear speeds of the two rollers.

[0032] Hydraulic motor 13 can be either the Rexroth A2FE63 (large displacement) or the A10VO28 (small displacement). The A2FE63 series swashplate motor has a displacement of 63 cm³ / rev and a maximum pressure of 450 bar, providing high torque for large-radius rollers. The A10VO28 axial piston variable displacement motor has a displacement of 28 cm³ / rev and a wide speed range (80~3000 rpm), suitable for precise speed control of small rollers. Both conform to the ISO 3019 standard interface, facilitating integration into independent hydraulic control systems.

[0033] It is worth noting that both the first roller 2 and the second roller 3 have several sets of buffer protrusions 14 evenly distributed circumferentially on their outer arc surfaces. The cross-section of each buffer protrusion 14 is semi-circular, and its outer arc surface is provided with several sets of anti-slip textures 15. During the paving operation, a significant impact force is generated when the paving material contacts the rollers. The semi-circular buffer protrusions 14 can effectively absorb and disperse this impact force through their elastic deformation, reducing the rigid collision between the paving material and the rollers. This not only protects the surface of the paving material from damage by the rollers, preventing scratches and breakage, and ensuring the integrity and performance of the paving material, but also reduces the impact load on the rollers during operation, lessening wear and extending their service life.

[0034] Specifically, an annular gasket 16 is installed on the side wall of cavity 4 to buffer the limiting ring 5. The inner side wall of the annular gasket 16 fits against the outer side wall of the limiting ring 5. During the laying vessel operation, when the second roller 3 slides in cavity 4, the limiting ring 5 may collide with the side wall of cavity 4 due to external impact, load changes, or its own inertia. The annular gasket 16 has a certain degree of elasticity and can absorb the impact force through its own elastic deformation at the moment of contact between the limiting ring 5 and the side wall of cavity 4, reducing the rigid collision between the two, thereby reducing the vibration and noise generated by the collision, protecting the limiting ring 5 and the side wall of cavity 4 from damage, and extending the service life of related components.

[0035] More specifically, the base 1 has several sets of threaded holes 17 in its center for fixing the base 1. Each set of threaded holes 17 contains bolts 18 for connecting the base 1 to the hull. The threaded holes 17 provide a mounting foundation for the fixed connection between the base 1 and the hull. These threaded holes are distributed in a specific layout to form a stable array of connection points. By cooperating with the bolts 18, the base 1 is firmly fixed to the hull, effectively preventing the base 1 from loosening or shifting when subjected to external forces. This provides a reliable support foundation for the entire laying vessel's roller load-bearing device, ensuring the stable installation of the device on the hull.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
