[0001] The utility model belongs to the technical field of rail transit, and particularly relates to a floating slab adapter and a floating slab track system with the same. Background Art

[0002] The vibration and noise problems caused by urban rail transit have a non-negligible impact on the lives of residents along the line and even the structural safety of the overlying buildings. The floating slab track bed system is one of the means with the strongest comprehensive performance among many existing vibration reduction track design schemes, and has been widely applied in the field of urban rail transit.

[0003] At present, the floating slab vibration reduction track is one of the implementation schemes of the vibration reduction track system with the strongest comprehensive vibration isolation performance. The installation and positioning of the floating slab track bed is an important link in the construction and installation. The existing floating slab height adjustment scheme usually realizes the adjustment by installing gaskets between the floating slab and the vibration isolator, which cannot realize stepless height adjustment, and at the same time increases the working difficulty of installation, maintenance and other measures. The relative height adjustment accuracy between the vibration isolator and the floating slab is insufficient, which may lead to uneven supporting reaction forces of the track system on the vibration isolation structure, resulting in a decline in vibration isolation performance, track smoothness and stability, and even may cause damage to the track structure.

[0004] The use of the adapter also does not require replacing the embedded structure in the floating slab to connect the vibration isolator. Through this transition piece of the adapter, the transition connection between the vibration isolator and the floating slab is realized, improving the versatility of the product.

[0005] Chinese Patent CN202223369376.9 discloses a spiral adjustment adapter and its track system. Although it discloses the adapter structure used in cooperation with the vibration isolator, the outer sleeve structure used in cooperation is relatively complex, the installation is unstable, and there is a risk of dislocation between the outer sleeve and the adapter, which will affect the smoothness when the train passes and the stability of the track vibration reduction system.

[0006] Therefore, how to provide a floating slab adapter and a floating slab track system with the same, which have a simple structure, are convenient to assemble and can be adjusted steplessly with high precision, is an urgent problem to be solved by those skilled in the art.

A baffle for restricting the unidirectional rotation of the bearing platform is provided on the inner side wall of the floating slab embedded cylinder. A pin block is adaptively inserted between adjacent bosses, and the pin block is used to restrict the reverse rotation of the bearing platform.

[0018] The resulting technical effect is that the baffle can be used to restrict the unidirectional rotation of the bearing platform, thereby restricting the unidirectional rotation angle of the adapter cylinder. Then, the pin block is used to restrict the rotation of the bearing platform, so as to restrict the circumferential rotation of the adapter cylinder. By using the positioning bolts, lapping blocks and bearing platform to restrict the up-and-down movement of the adapter cylinder in the vertical direction, the installation stability of the floating slab embedded cylinder and the adapter is ensured.

[0019] The present utility model also discloses a floating slab track system, which includes a plurality of the above-mentioned floating slab adapters, floating slab embedded cylinders, floating slab bodies and floating slab vibration isolators.

[0022] The resulting technical effect is that the non-linear rubber vibration isolator provides a non-linear damping vibration damping effect, avoiding the occurrence of low-frequency resonance phenomenon when the train passes by, and improving the stability and smoothness of the track system.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0047] Embodiment 1

[0048] Refer to the accompanying drawings of the present invention Figures 1 to 3 According to an embodiment of the present invention, a floating slab adapter is installed in the floating slab embedded cylinder 1. There is a boss 2 and an adapter cylinder 3 in the floating slab embedded cylinder 1. A thread structure 4 capable of infinitely adjusting the height in cooperation with the floating slab vibration isolator 15 is provided on the inner side wall of the adapter cylinder 3;

[0049] Bearing platform 5. A plurality of bearing platforms 5 are provided on the outer side wall of the adapter cylinder 3, and the bearing platforms 5 abut and are carried below the boss 2;

[0050] The lapping block 6 on the top edge ring of the outer side wall of the adapter cylinder 3 is an annular block. The distance between the lapping block 6 and the bearing platform 5 up and down needs to meet the entry of the boss. The annular block is located above the boss 2. A plurality of limit holes 7 are circumferentially spaced on the annular block. The limit holes are threaded holes. Screw holes 8 cooperating with the limit holes 7 are provided on the boss 2. The number of screw holes corresponds to the number of limit holes and can be coaxially penetrated by positioning bolts 9. The positioning bolts are connected in the screw holes 8.

[0051] There are multiple bosses 2 on the floating plate embedded tube 1, and the multiple bosses are located in the same horizontal plane and are spaced apart in the circumferential direction. There is a channel 10 between adjacent bosses 2 through which the bearing platform 5 passes. During installation, the bearing platform on the adapter cylinder is aligned with the channel and moved down until the annular block overlaps the boss, and then the angle of the adapter cylinder is adjusted so that the position of the limit hole corresponds to the position of the screw hole, and the positioning bolt 9 is connected to achieve the installation of the adapter and the floating plate embedded tube. Under this structure, the inner wall of the floating plate embedded tube only needs a boss structure, which simplifies the structure of the existing floating plate embedded tube. Of course, the outer wall of the floating plate embedded tube has a rib plate to strengthen the connection with the floating plate body.

[0052] Example 2

[0053] Reference Figures 4 - 6 , Embodiment 2 is different from Embodiment 1 in that there is no need to change the structure of the traditional floating plate embedded tube. In Embodiment 2, the lap block 6 on the adapter tube is a plurality of split blocks, and the plurality of split blocks are circumferentially spaced on the outer wall of the adapter tube 3. Each split block is provided with a limit hole 7, and the limit hole is a threaded hole. There are multiple bosses 2 on the floating plate embedded tube 1, and the multiple bosses are equidistantly spaced in the circumferential direction. There is no need to set screw holes on the bosses of Embodiment 2. A baffle 11 is provided on the inner wall of the floating plate embedded tube 1 to limit the unidirectional rotation of the bearing platform 5. Note that the baffle 11 is set at the position to ensure that the other side end of the bearing platform is completely hidden below the boss. During installation, the baffle can limit the rotation angle of the adapter tube. Pin blocks 12 are adapted to be inserted between adjacent bosses 2. It should be noted that the pin blocks need to match the shape of the channel between adjacent bosses to avoid left and right shaking of the pin blocks after insertion. The pin blocks just fill the channel space. When the pin blocks are installed, they are embedded in the pre-embedded A step for supporting the pin block is provided at the bottom of the inner wall of the cylinder, so there is no need to worry about the installation of the pin block. The pin block is used to limit the reverse rotation of the bearing platform. That is to say, during the specific installation, after the pin block is inserted, the two side ends of the bearing platform are in contact with the baffle and the limit block, which is used to limit the circumferential rotation of the adapter cylinder, and then the positioning bolt is connected to the limit hole. The end of the positioning bolt is tightly pressed against the boss to limit the vertical displacement of the adapter (in the direction of the up and down jumping of the floating plate). In this way, when adjusting the vibration isolator, there is no need to worry about the unstable relationship between the adapter and the floating plate embedded tube, and the rotation of the adapter can be limited, and the up and down movement of the adapter relative to the floating plate embedded tube can be limited.

[0054] The present utility model also discloses a floating slab track system, which includes a plurality of the above-mentioned floating slab adapters 13, floating slab embedded cylinders 1, floating slab bodies 14 and floating slab vibration isolators 15. The floating slab embedded cylinders 1 are embedded in the floating slab bodies 14 at intervals along the length direction of the rail. Each floating slab embedded cylinder 1 is connected with a floating slab adapter 13. The supporting components of the floating slab embedded cylinders 1 and the floating slab adapters 13 are arranged in two columns along the length direction of the rail. The outer side of the floating slab vibration isolator 15 is provided with an external thread that matches the thread structure of the adapter cylinder body. In this way, the stepless and high-precision adjustment of the floating slab can be realized by rotating the floating slab vibration isolator 15, improving the assembly precision, smoothness and stability of the floating slab vibration reduction track system.

[0055] Specifically, the floating slab vibration isolator 15 is a non-linear rubber vibration isolator, which can avoid the low-frequency resonance problem when the train passes by and also reduce the noise impact. The floating slab vibration isolator 15 includes an adjustment table 151, a base 152, a buffer vibration reduction component 153 and a central rod 154. The outer side of the adjustment table 151 is provided with an external thread structure, and the external thread structure matches the thread structure 4 of the adapter cylinder body. The adjustment table 151 is provided with a central hole; the base 152 is located below the adjustment table 151 as a support foundation, and the base 152 is inserted and sleeved with the adjustment table 151 and can rotate synchronously; the buffer vibration reduction component 153 is placed between the adjustment table 151 and the base 152 to realize the distance adjustment between the adjustment table and the base; the central rod 154 penetrates through the adjustment table 151 and the buffer vibration reduction component 153 and is detachably connected to the base 152. The top end of the central rod 154 limits the initial installation distance between the adjustment table 151 and the base 152.

[0056] Among them, the adjustment table 151 is provided with a hexagonal counterbore 1511, the top of the adjustment table 151 is provided with a screw hole 1512, a slot hole is opened on the side wall of the adjustment table 151 corresponding to the hexagonal counterbore, the top of the slot hole is communicated with the screw hole 1512, a lock 1513 is inserted in the slot hole, one end of the lock 1513 is provided with a biting groove, and the biting groove is similar to a serrated groove, aiming to bite the thread structure 4 on the adapter cylinder body. The other end of the lock 1513 is provided with an inclined surface, and a screw 1514 is threadedly connected in the screw hole. When the screw is tightened, the conical surface of the screw abuts against the inclined surface of the lock, and the conical surface of the screw 1514 urges the lock to move towards the adapter cylinder body 3 direction. The biting groove on the lock bites with the thread structure of the adapter cylinder body, so as to realize the position limitation of the vibration isolator and the adapter, prevent the vibration isolator from loosening during use, and thus affect the smoothness of the track system and the vibration reduction performance of the track system.

[0057] System example one, refer to the appendix Figure 7, on the basis of Embodiment 1, the first non-linear rubber isolator is used in a supporting manner. The isolator can rotate synchronously during adjustment. A convex perforated square rod 155 is provided in the middle of the bottom of the adjustment table 151, and an inner square hole 156 matching the perforated square rod is provided in the middle of the base 152. The perforated square rod 155 is slidably connected up and down in the inner square hole 156, and the central rod 154 is located in the hole of the perforated square rod 155. When the adjustment table is rotated, the lower base will rotate accordingly, avoiding the frictional loss of the buffer and vibration damping components between the adjustment table and the base, and also ensuring the reaction force requirements of the buffer and vibration damping components. In this application example, the buffer and vibration damping component is a V-shaped rubber-steel laminate. The V shape means that the cross-section of the rubber-steel laminate in the rotating section is V-shaped. Compared with the spring isolator, it has a stronger longitudinal and transverse (corresponding to the longitudinal and transverse directions of the floating slab) support stiffness effect, higher stability, and is not easy to shake. For the specific internal hexagonal fitting, refer to the appendix Figure 13 .

[0058] System Example Two, refer to the appendix Figure 8 , also on the basis of Embodiment 1, a second isolator is used in a supporting manner. Different from the isolator in Example One, a first staggered tooth structure 157 is provided in a ring shape at the bottom of the adjustment table 151, and a second staggered tooth structure 158 is provided in a ring shape at the top of the base 152. The first staggered tooth structure 157 is adaptively inserted and synchronously rotated with the second staggered tooth structure 158, and there is a downward pressing gap between the teeth of the first staggered tooth structure 157 and the grooves of the corresponding second staggered tooth structure 158. In this application example, the buffer and vibration damping component is a V-shaped rubber-steel laminate, which has a stronger longitudinal and transverse (corresponding to the longitudinal and transverse directions of the floating slab) support stiffness effect, higher stability, and is not easy to shake. For the specific cooperation of the first staggered tooth structure and the second staggered tooth structure, refer to the appendix Figure 14 .

[0059] System Example Three, refer to the appendix Figure 9 , on the basis of Embodiment 1, a third non-linear rubber isolator is used. Different from the isolator in Example Two, a first cylinder structure 159 extends from the bottom of the adjustment table 151. A limiting groove is provided on the inner side of the first cylinder structure 159, and a second cylinder structure 160 is provided on the top of the base 152. A limiting block is provided on the outer side wall of the second cylinder structure 160. The first cylinder structure 159 is adaptively inserted outside the second cylinder structure 160, and the limiting block is slidably connected with the limiting groove in an adaptive manner. In this application example, the buffer and vibration damping component is a V-shaped rubber-steel laminate, which has a stronger longitudinal and transverse (corresponding to the longitudinal and transverse directions of the floating slab) support stiffness effect, higher stability, and is not easy to shake. For the specific cooperation of the first staggered tooth structure and the second staggered tooth structure, refer to the appendix Figure 15 .

[0060] System Examples One to Three are all extended applications under the adapter structure of Embodiment 1.

V-shaped, folded and flat are all in terms of the cross-section of the rotating body.
