Description

Technical Field

[0001] The utility model relates to the technical field of floating dock steel approach bridges, and particularly relates to a roller support for a floating dock steel approach bridge and a floating dock steel approach bridge. Background Art

[0002] The steel approach bridge is a common hydraulic structure in inland river terminal projects. It can be classified into movable steel approach bridges and fixed steel approach bridges according to whether it can move. Among them, the movable steel approach bridge is widely used in floating docks because it can conveniently adjust its position automatically with the change of water level. The common supports for steel approach bridges mainly include flat supports, rubber supports, arc supports, roller supports, etc. Due to its functional requirements, the movable steel approach bridge usually adopts arc supports and roller supports. The commonly used roller support adopts a structural form in which rollers are installed under the fixed support. This type of support usually has poor load-bearing capacity. To operate under heavy loads, only the wheel diameter and wheel thickness can be increased, which has certain limitations. In addition, as the water level of the river rises and falls, the inclination angle of the steel approach bridge will change. When the inclination angle of the steel approach bridge is relatively large, the mounting frame for installing the rollers will tilt with the steel approach bridge due to the angle change, which may cause the steel approach bridge to abut against the pontoon, resulting in the rollers being unable to play a supporting role and causing deformation and damage to the structure of the steel approach bridge.

[0003] In summary, there is an urgent need for a roller support for a floating dock steel approach bridge and a floating dock steel approach bridge to solve or at least partially solve the problems existing in the prior art. Content of the Utility Model

[0004] The purpose of the utility model is to provide a roller support for a floating dock steel approach bridge, aiming to solve the problem of poor load-bearing capacity of the existing roller support. The specific technical solution is as follows:

[0005] A roller support for a floating dock steel approach bridge includes a mounting seat, a fixed seat and at least two rollers, and also includes a first connecting shaft and a second connecting shaft. The second connecting shafts are arranged in one-to-one correspondence with the rollers. The mounting seat is rotatably connected to the upper part of the fixed seat through the first connecting shaft, and the rollers are rotatably connected to the bottom of the mounting seat through the corresponding second connecting shafts, and multiple rollers are arranged side by side.

[0006] Furthermore, it also includes a bushing, the bushing is sleeved outside the first connecting shaft, and the fixed seat is rotatably connected to the bushing.

[0007] Furthermore, it also includes a first spacer and a second spacer. There are two first spacers, and the two first spacers are respectively arranged at both ends of the bushing, and the first spacer is located between the fixed seat and the bushing;

[0008] Two second spacers are arranged corresponding to each roller, and the two second spacers are respectively arranged at both ends of the roller, and the second spacer is located between the mounting seat and the roller.

[0009] Further, it further includes a limiting plate and a fastener for fastening the limiting plate to the mounting seat. A limiting groove is provided at the end of the second connecting shaft along the radial direction of the second connecting shaft. The limiting plate is partially embedded in the limiting groove along the radial direction of the second connecting shaft, and the fastener connects the mounting seat and the limiting plate.

[0010] Further, two limiting plates are correspondingly arranged for each second connecting shaft. Limiting grooves are arranged at both ends of the second connecting shaft. The two limiting plates are respectively embedded in the limiting grooves at both ends of the second connecting shaft, and the two limiting plates are both fixedly connected to the mounting seat through fasteners.

[0011] Further, the mounting seat includes a mounting plate, a first ear plate and a second ear plate. The mounting plate is horizontally arranged. There are two first ear plates, and the two first ear plates are arranged in parallel above the mounting plate. First connecting holes are arranged on both first ear plates, and the first connecting holes on the two first ear plates are coaxially arranged. The first connecting shaft is connected to the two first ear plates through the two first connecting holes respectively, and the fixing seat is arranged between the two first ear plates;

[0012] The two second ear plates are arranged in parallel below the mounting plate, and at least two second connecting holes are arranged on the two second ear plates. The second connecting holes on one second ear plate are arranged oppositely to the second connecting holes on the other second ear plate. The second connecting shaft is connected to the second ear plate through the second connecting holes, and the rollers are arranged between the two second ear plates.

[0013] Further, it further includes a flexible pad. The flexible pad is arranged on the top of the fixing seat. A plurality of first mounting holes are arranged on the fixing seat, and second mounting holes are provided on the flexible pad. The second mounting holes are arranged corresponding to the first mounting holes.

[0014] Further, weight-reducing grooves are arranged on both sides of the roller.

[0015] Further, a first reinforcing rib and a second reinforcing rib are also arranged on the mounting seat. One end of the first reinforcing rib is welded to the first ear plate, and the other end of the first reinforcing rib is welded to the mounting plate. The first reinforcing rib is arranged on the side of the first ear plate away from the fixing seat;

[0016] One end of the second reinforcing rib is welded to the second ear plate, and the other end of the second reinforcing rib is welded to the mounting plate, and the second reinforcing rib is arranged on the side of the second ear plate away from the roller.

[0017] Applying the technical solution of the present utility model has the following beneficial effects:

[0018] Supported on the barge by at least two rollers, the supporting area is increased. In addition, supported by multiple rollers, the load is dispersed, and the bearing capacity of the steel approach bridge is improved without increasing the diameter and width of the rollers. The rollers do not need to be enlarged and widened, which is convenient for arrangement and installation.

[0019] During use, the inclination angle of the steel access bridge changes with the rise and fall of the water level. When the angle of the steel access bridge changes, the fixed seat rotates relative to the mounting seat, ensuring that the two rollers can always support on the pontoon. During the rotation of the fixed seat, the mounting seat does not rotate accordingly. Therefore, the mounting seat will not abut against the pontoon, causing damage to the structure of the steel access bridge, enabling the steel access bridge to rotate smoothly. In addition, the mounting seat and the fixed seat are connected by a hinge. During design, the position of one end of the steel access bridge on the pontoon is raised, thereby reducing the inclination angle of the steel access bridge between the roller support and the arc support, which is beneficial for transporting goods or pedestrians to walk.

[0020] In addition, through the hinge connection between the fixed seat and the mounting seat, the steel access bridge can operate at a larger rotation angle, expanding the applicable range of the steel access bridge for water level drop and slope.

[0021] The present utility model also provides a floating dock steel access bridge, including an access bridge body, an arc support, and a mobile support mechanism. The first end of the access bridge body is connected to the arc support and supported on the fixed pile of the dock. The second end of the access bridge body is connected to the mobile support mechanism. Both the arc support and the mobile support mechanism are arranged at the lower part of the access bridge body. The mobile support mechanism includes a connecting rod and the above-mentioned floating dock steel access bridge roller support. Both floating dock steel access bridge roller supports are installed at one end of the access bridge body away from the arc support, and the two floating dock steel access bridge roller supports are relatively arranged at both ends of the connecting rod. The fixed seat of the floating dock steel access bridge roller support is fixedly connected to the bottom surface of the access bridge body.

Detailed implementation manners

[0031] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below, and preferred embodiments of the present utility model are given. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present utility model more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0033] Embodiment:

[0034] Refer to Figures 1-3 , this embodiment provides a floating dock steel approach bridge roller support, including a mounting seat 2, a fixed seat 1 and at least two rollers 3, further including a first connecting shaft 4 and a second connecting shaft 5. The second connecting shafts 5 are arranged in one-to-one correspondence with the rollers 3. The mounting seat 2 is rotatably connected to the upper part of the fixed seat 1 through the first connecting shaft 4, and the rollers 3 are rotatably connected to the bottom of the mounting seat 2 through the corresponding second connecting shafts 5, and a plurality of rollers 3 are arranged side by side.

[0035] This embodiment will be described with the case of two rollers 3. Specifically, the two rollers 3 are respectively rotatably connected to two second connecting shafts 5, and the two second connecting shafts 5 are installed on the mounting bracket. It should be noted that the two second connecting shafts 5 are arranged in parallel with each other, and both of the two second connecting shafts 5 are parallel to the first connecting shaft 4. The fixed seat 1 is fixed on the barge by bolts, or the fixed seat 1 is fixed on the barge by welding. The two rollers 3 support on the barge and jointly play a supporting role for the steel approach bridge.

[0036] It can be understood that by supporting the steel approach bridge with two rollers 3, the supporting area is increased. In addition, by supporting with multiple rollers 3, the load is dispersed, and the bearing capacity of the steel approach bridge is improved without increasing the diameter and width of the rollers 3. The rollers 3 do not need to be enlarged and widened, which is convenient for arrangement and installation. In addition, during use, the inclination angle of the steel approach bridge will change with the rise and fall of the water level. When the angle of the steel approach bridge changes, the fixed seat 1 rotates relative to the mounting seat 2, so that the two rollers 3 can always support on the barge. During the rotation of the fixed seat 1, the mounting seat 2 will not rotate accordingly. Therefore, the mounting seat 2 will not abut against the barge and cause damage to the structure of the steel approach bridge, enabling the steel approach bridge to rotate smoothly. When designing, if the rotation angle of the steel approach bridge is large, the height of the mounting seat 2 can be increased, thereby increasing the distance between the fixed seat 1 and the barge, so that during the rotation of the steel approach bridge, the fixed seat 1 will not abut against the barge. In addition, the mounting seat 2 and the fixed seat 1 are connected by hinges. During design, the position of one end of the steel approach bridge on the barge is raised, so that the inclination angle of the steel approach bridge between the roller support and the arc-shaped support 13 becomes smaller, which is beneficial for transporting goods or pedestrians to walk.

[0037] Furthermore, it also includes a bushing 6. The bushing 6 is sleeved outside the first connecting shaft 4, and the fixed seat 1 is rotatably connected to the bushing 6. It can be understood that the bushing 6 is made of wear-resistant materials such as tin bronze and aluminum bronze. Through the setting of the bushing 6, the friction between the fixed seat 1 and the first connecting shaft 4 is reduced, making the rotation of the fixed seat 1 relative to the mounting seat 2 and the first connecting shaft 4 smoother. In addition, through the setting of the bushing 6, it plays a protective role for the first connecting shaft 4 and improves the service life of the first connecting shaft 4. Secondly, the bushing 6 can be replaced in time after wear, without replacing the first connecting shaft 4 or the fixed seat 1, reducing the maintenance cost.

[0038] Furthermore, it also includes a first spacer 7 and a second spacer 8. There are two first spacers 7, and the two first spacers 7 are respectively arranged at both ends of the bushing 6, and the first spacer 7 is located between the fixed seat 1 and the bushing 6;

[0039] Two second spacers 8 are arranged corresponding to each roller 3, and the two second spacers 8 are respectively arranged at both ends of the roller 3, and the second spacer 8 is located between the mounting seat 2 and the roller 3.

[0040] It can be understood that by arranging the first spacer sleeve 7 at both ends of the bushing 6, a gap is left between the bushing 6 and the mounting seat 2, and a gap is also left between the fixed seat 1 and the mounting seat 2, preventing friction between both sides of the fixed seat 1 and the mounting seat 2, which may cause damage to the fixed seat 1 or generate abnormal noises during the relative rotation of the fixed seat 1 and the mounting seat 2. By arranging the second spacer sleeve 8 at both ends of the roller 3, the roller 3 is separated from the mounting seat 2, preventing friction between the side surface of the roller 3 and the mounting seat 2, which may cause damage to the roller 3 or the mounting seat 2, and secondly, preventing abnormal noises caused by friction between the side surface of the roller 3 and the mounting seat 2.

[0041] Furthermore, it further includes a limiting plate 9 and a fastener 10 for fastening the limiting plate 9 to the mounting seat 2. A limiting groove is provided at the end of the second connecting shaft 5 along the radial direction of the second connecting shaft 5. The limiting plate 9 is partially embedded in the limiting groove along the radial direction of the second connecting shaft 5, and the fastener 10 connects the mounting seat 2 and the limiting plate 9.

[0042] It can be understood that when the second connecting shaft 5 is installed on the mounting seat 2, it may axially move along its own axis. Without limitation, it may cause the second connecting shaft 5 to fall off. By providing a limiting groove at one end of the second connecting shaft 5, during the installation process, a part of the limiting plate 9 is embedded in the limiting groove to prevent the second connecting shaft 5 from axially moving. The limiting plate 9 is connected to the mounting seat 2 through the fastener 10. In this embodiment, the fastener 10 is a screw. In other embodiments, the fastener 10 can also be components or structures such as bolts and rivets. Of course, it should be noted that a limiting groove is also arranged on the first connecting shaft 4, and a limiting plate 9 is fastened to the fixed seat 1 by a screw. A part of the limiting plate 9 is embedded in the limiting groove at the end of the first connecting shaft 4 to limit the first connecting shaft 4.

[0043] Furthermore, two limiting plates 9 are arranged corresponding to each second connecting shaft 5. Limiting grooves are arranged at both ends of the second connecting shaft 5. The two limiting plates 9 are respectively embedded in the limiting grooves at both ends of the second connecting shaft 5, and the two limiting plates 9 are both fixedly connected to the mounting seat 2 through the fastener 10.

[0044] It can be understood that by using two limiting plates 9 to limit both ends of the second connecting shaft 5 at the same time, redundant limiting is increased, and the stability of limiting the second connecting shaft 5 is improved.

[0045] Further, the mounting base 2 includes a mounting plate 21, a first ear plate 22 and a second ear plate 23. The mounting plate 21 is horizontally arranged. There are two first ear plates 22, and the two first ear plates 22 are arranged in parallel above the mounting plate 21. First connection holes 221 are arranged on both of the two first ear plates 22. The first connection holes 221 on the two first ear plates 22 are coaxially arranged. The first connection shaft 4 is connected to the two first ear plates 22 through the two first connection holes 221 respectively. The fixing base 1 is arranged between the two first ear plates 22;

[0046] The two second ear plates 23 are arranged in parallel below the mounting plate 21, and at least two second connection holes 231 are arranged on the two second ear plates 23. The second connection holes 231 on one second ear plate 23 are arranged opposite to the second connection holes 231 on the other second ear plate 23. The second connection shaft 5 is connected to the second ear plates 23 through the second connection holes 231. The roller 3 is arranged between the two second ear plates 23.

[0047] Further, a flexible pad 11 is also included. The flexible pad 11 is arranged on the top of the fixing base 1. A plurality of first mounting holes 101 are arranged on the fixing base 1. Second mounting holes 111 are provided on the flexible pad 11, and the second mounting holes 111 are arranged corresponding to the first mounting holes 101. It can be understood that the flexible pad 11 is made of rubber. During installation, the fixing base 1 is fixedly connected to the steel approach bridge by bolts passing through the first mounting holes 101 and the corresponding second mounting holes 111. By arranging the flexible pad 11 on the top of the fixing base 1, when the bolts are tightened, it is prevented that the fixing base 1 presses on the steel approach bridge and damages the bottom surface of the steel approach bridge. In other embodiments, the flexible pad 11 can also be made of materials such as silica gel, polyurethane, felt, etc.

[0048] Further, weight reduction grooves 31 are arranged on both sides of the roller 3. It can be understood that through the setting of the weight reduction grooves 31, the overall weight of the roller 3 is reduced, making the whole device lighter. In addition, through the arrangement of the weight reduction grooves 31, the use of materials is reduced. When directly casting, more rollers 3 can be manufactured with the same material, improving the material utilization rate.

[0049] Further, a first reinforcing rib 24 and a second reinforcing rib 25 are also arranged on the mounting base 2. One end of the first reinforcing rib 24 is welded to the first ear plate 22, and the other end of the first reinforcing rib 24 is welded to the mounting plate 21. The first reinforcing rib 24 is arranged on the side of the first ear plate 22 away from the fixing base 1; One end of the second reinforcing rib 25 is welded to the second ear plate 23, and the other end of the second reinforcing rib 25 is welded to the mounting plate 21. And the second reinforcing rib 25 is arranged on the side of the second ear plate 23 away from the roller 3.

[0050] Understandably, through the arrangement of the first reinforcing rib 24, the connection strength between the first ear plate 22 and the mounting plate 21 is enhanced, and the rigidity of the first ear plate 22 is enhanced, improving the ability of the first ear plate 22 to resist deformation. Through the arrangement of the second reinforcing rib 25, the connection strength between the second ear plate 23 and the mounting plate 21 is enhanced, and the rigidity of the second ear plate 23 is enhanced, improving the ability of the second ear plate 23 to resist deformation.

[0051] See Figures 4-6 , this embodiment provides a floating dock steel approach bridge, including an approach bridge body 12, an arc-shaped support 13 and a mobile support mechanism 14. The first end of the approach bridge body 12 is hinged to the arc-shaped support 13 and supported on the fixed piles of the dock. The second end of the approach bridge body 12 is connected to the mobile support mechanism 14. Both the arc-shaped support 13 and the mobile support mechanism 14 are arranged at the lower part of the approach bridge body 12. The mobile support mechanism 14 includes a connecting rod 141 and the above-mentioned floating dock steel approach bridge roller support 142. Both floating dock steel approach bridge roller supports 142 are installed at one end of the approach bridge body 12 away from the arc-shaped support 13, and the two floating dock steel approach bridge roller supports 142 are relatively arranged at both ends of the connecting rod 141. The fixed seat 1 of the floating dock steel approach bridge roller support 142 is fixedly connected to the bottom surface of the approach bridge body 12.

[0052] Understandably, the two floating dock steel approach bridge roller supports are respectively installed at one end of the approach bridge body 12 close to the pontoon bridge, and the two floating dock steel approach bridge roller supports are respectively arranged on both sides of the lower part of the approach bridge body 12. On the one hand, the bearing capacity of the floating dock steel approach bridge roller support for the approach bridge body 12 is improved. On the other hand, the two floating dock steel approach bridge roller supports are arranged on both sides of the approach bridge body 12 to prevent the approach bridge body 12 from rotating and tipping over. By connecting the two floating dock steel approach bridge roller supports through the connecting rod 141, the rigidity and integrity of the connection between the floating dock steel approach bridge roller supports are improved.
