Description

Technical Field

[0001] The invention belongs to the technical field of spherical steel bearings, in particular to an adjustable height anti-seismic spherical steel bearing for rail transportation. Background Art

[0002] Spherical steel bearings are products used for wide bridges and curved bridges. They have the characteristics of reliable force transmission, flexible rotation, greater load-bearing capacity than pot-type rubber bearings, and larger allowable bearing displacement. They are also components that can better adapt to the needs of large bearing rotation angles.

[0003] For example, a patent application CN109868732A discloses a spherical steel bearing for an aerial rail transit bridge, so that the longitudinal, transverse and vertical displacements of the beam body can be adjusted during the construction of the beam-pier-beam connection, thereby reducing the accuracy of the pier-beam connection construction and the difficulty of construction, thereby facilitating construction and improving construction efficiency. It is arranged between the beam body and the pier body, and includes an upper support plate, a lower support plate and a spherical crown lining plate located therebetween. The bottom surface of the lower structure of the upper support plate and the upper spherical surface of the spherical crown lining plate form a rotating friction pair, and the bottom surface of the spherical crown lining plate and the top surface of the lower support plate form a sliding friction pair. Longitudinal adjustment holes are longitudinally spaced on both sides of the upper support plate, and an upper connecting bolt connecting the upper support plate and the beam body is arranged at each longitudinal adjustment hole. Transverse adjustment holes are longitudinally spaced on both sides of the lower support plate, and a lower connecting bolt connecting the lower support plate and the pier body is arranged at each transverse adjustment hole.

[0004] Although the above technology can reduce the difficulty of construction, thus facilitating construction and improving construction efficiency, after it was put into use, maintenance personnel found that when a vehicle passed, the upper support plate and the lower support plate were offset, causing friction at the spherical crown lining plate, generating heat energy. During the passage of the vehicle, the frictional force converted the work into internal energy, which accumulated on the upper support plate and the lower support plate, affecting the service life of the entire device.

[0005] At the same time, when friction occurs at the ball crown lining, the small amount of debris generated by the friction cannot be discharged. After the friction debris accumulates, the friction damage is further expanded during friction, thereby affecting the service life.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] like Figures 1 to 9 As shown, the adjustable height earthquake-resistant spherical steel bearing for rail transit of the present invention comprises a supporting part, a heat exchange mechanism, a circulation mechanism and a filtering mechanism.

[0049] The support part includes an upper bearing seat 1, a lower bearing seat 2 and a spherical crown 8. The upper bearing seat 1 is arranged above the lower bearing seat 2. A threaded rod is arranged at the upper end of the upper bearing seat 1 for connecting with the track. The lower bearing seat 2 is used to connect with the ground.

[0050] The spherical crown 8 is arranged at the bottom of the upper bearing seat 1, and a groove adapted to the spherical crown 8 is opened above the lower bearing seat 2. A polytetrafluoroethylene plate is arranged in the groove and fits with the outer wall of the spherical crown 8. An insulating wear-resistant ring is arranged between the upper bearing seat 1 and the lower bearing seat 2. At the same time, in order to achieve a sealed connection between the upper bearing seat 1 and the lower bearing seat 2, a rubber connecting piece is arranged between the upper bearing seat 1 and the lower bearing seat 2.

[0051] The ball crown 8 design can evenly distribute the load, reduce local stress and improve the stability of the structure. At the same time, the ball crown 8 and the groove cooperate to allow free movement in multiple directions, which can effectively cope with the horizontal displacement and rotation of the structure and reduce stress concentration caused by temperature changes or earthquakes.

[0052] The heat exchange mechanism includes a mounting tube 7 , a heat exchange plate 4 and a partition plate 9 . The mounting tube 7 is fixedly mounted on the bottom of the lower bearing seat 2 . The inner cavity of the mounting tube 7 is divided into two chambers by the partition plate 9 , wherein the partition plate 9 is fixedly mounted on the inner wall of the mounting tube 7 .

[0053] The heat exchange plate 4 is fixedly mounted on the inner wall of the mounting tube 7. The heat exchange plate 4 is a common tube plate. The chamber between the upper bearing seat 1 and the lower bearing seat 2 is connected to the inner cavity of the mounting tube 7. Coolant is injected into one side of the partition plate 9. After the coolant enters the inner cavity of the mounting tube 7, it enters the chamber between the upper bearing seat 1 and the lower bearing seat 2, and is then discharged from the other side of the partition plate 9.

[0054] When the coolant flows into the cavity between the upper bearing seat 1 and the lower bearing seat 2, the heat generated by the friction of the ball crown 8 is taken away. At the same time, the debris generated by the friction of the ball crown 8 is discharged along with the flow of the coolant. In actual use, when a vehicle passes, the temperature of the ball crown 8 can be reduced, and the debris generated by the friction can be discharged, thereby increasing the service life of the entire device.

[0055] The circulation mechanism includes an installation box 6, a connecting tube 13 and a circulation pump 12. The circulation pump 12 is arranged in the installation box 6, and the input end is connected to one end of the connecting tube 13. The other end of the connecting tube 13 and the output end of the circulation pump 12 are both used to connect to the inner cavity of the installation tube 7. The circulation pump 12 is used as a power source for the flow of coolant.

[0056] The filtering mechanism is used to filter impurities in the connecting tube 13. By filtering impurities in the coolant, during use, it prevents debris generated by friction from flowing into the chamber between the upper bearing seat 1 and the lower bearing seat 2 again, thereby maintaining continuous cleaning.

[0057] The bottom of the heat exchanger fin 4 extends to the outer wall of the mounting tube 7 and is fixedly installed with a support ring 3, wherein one end of the heat exchanger fin 4 extending to the outside of the mounting tube 7 is pre-buried in the ground, and the heat in the coolant is absorbed by the heat exchanger fin 4 and transferred to the ground to achieve cooling of the coolant. The support ring 3 is provided to improve the structural strength of the heat exchanger fin 4.

[0058] A spiral tube 5 is fixedly installed on the outer wall of the mounting tube 7. Two spiral tubes 5 are provided. The two spiral tubes 5 are respectively connected to two chambers separated by the partition plate 9. One of the spiral tubes 5 is connected to one end of the connecting tube 13, and the other spiral tube 5 is connected to the output end of the circulating pump 12, so as to control the circulation of the coolant when the circulating pump 12 is working.

[0059] The spiral tube 5 is a copper tube, which is pre-buried in the bottom surface when in use. When the coolant flows, the time for the coolant to flow underground can be effectively increased, thereby facilitating the cooling of the coolant.

[0060] As a preferred embodiment of the present invention, the filtering mechanism includes a support frame 18, a filter layer 17 and a collecting tube 11. The support frame 18 is arranged in the inner cavity of the connecting tube 13, and the support frame 18 is inclined toward the liquid inlet direction of the connecting tube 13. The connecting tube 13 provides an installation position for the support frame 18.

[0061] The filter layer 17 is disposed in the support frame 18 , so that impurities in the coolant are filtered through the filter layer 17 during the flow of the coolant.

[0062] The collecting cylinder 11 is fixedly mounted on the outer wall of the connecting cylinder 13, and the collecting cylinder 11 is located directly below the supporting frame 18. When the coolant flows, the impurities are flushed into the interior of the collecting cylinder 11 along the inclined outer wall of the filter layer 17. The impurities are collected by the collecting cylinder 11, thereby reducing the content of impurities in the connecting cylinder 13 as much as possible and increasing the service life of the filtration.

[0063] The inner wall of the collecting cylinder 11 is provided with a rubber sheet 21. The rubber sheet 21 is a fan-shaped structure, and a plurality of rubber sheets 21 are provided along the axis of the collecting cylinder 11. The rubber sheet 21 is inclined toward the inner cavity of the collecting cylinder 11. Through the cooperation of the plurality of rubber sheets 21, when the coolant flows in the inner cavity of the connecting cylinder 13, the impurities in the inner cavity of the collecting cylinder 11 can be prevented as much as possible from flowing back into the inner cavity of the connecting cylinder 13.

[0064] A sealing cylinder 15 is detachably installed at the bottom of the collecting cylinder 11. The sealing cylinder 15 is connected to the collecting cylinder 11 through a thread and is used to seal the bottom of the collecting cylinder 11. A capturing layer 20 is obliquely arranged on the inner wall of the sealing cylinder 15. The capturing layer 20 is a common sponge structure and is used to absorb impurities after the impurities enter the collecting cylinder 11, thereby preventing the impurities from flowing into the inner cavity of the connecting cylinder 13 again.

[0065] A conical hole is formed on the inner wall of the collecting tube 11 , and a support frame 23 is fixedly mounted on the inner wall of the collecting tube 11 . A control rod 24 is elastically mounted on the upper end of the support frame 23 , and the control rod 24 is connected to the support frame 23 via a spring.

[0066] A sealing plug 22 for sealing the tapered hole is fixedly mounted on one end of the control rod 24 . The elastic force exerted on the control rod 24 controls the sealing plug 22 to have a tendency to seal the tapered hole in real time.

[0067] After the blocking tube 15 is assembled with the collecting tube 11 , the outer wall of the blocking tube 15 presses the control rod 24 , and the blocking plug 22 is controlled to separate from the tapered hole by the pressing control rod 24 , so as to realize the communication between the inner cavity of the collecting tube 11 and the connecting tube 13 .

[0068] When it is necessary to remove impurities in the inner cavity of the connecting tube 13, the sealing tube 15 is removed. During the removal of the sealing tube 15, the sealing plug 22 is driven by the elastic force of the spring to close the conical hole, thereby preventing the coolant in the inner cavity of the connecting tube 13 from flowing out.

[0069] As a preferred embodiment of the present invention, a mounting frame 19 is fixedly installed on the inner wall of the connecting cylinder 13, and a pressing shaft 31 for pressing the filter layer 17 is slidably installed in the inner cavity of the mounting frame 19. The filter layer 17 is made of elastic material. When the coolant flows through the filter layer 17, the filter layer 17 is squeezed to separate impurities from the filter layer 17.

[0070] A reciprocating groove 32 is provided on the radial outer wall of the pressing shaft 31, and a protrusion that slides with the reciprocating groove 32 is fixedly installed on the inner wall of the mounting frame 19. The pressing shaft 31 is rotated, and the reciprocating groove 32 and the protrusion inside the mounting frame 19 cooperate to make the pressing shaft 31 slide back and forth, thereby pressing the filter layer 17, and cooperating with the elasticity of the filter layer 17 itself to control the deformation and resetting of the filter layer 17 to facilitate the shedding of impurities.

[0071] A carrier plate 30 is fixedly mounted on the side wall of the mounting frame 19, and a guide plate 29 is fixedly mounted on the radial outer wall of the carrier plate 30. The guide plate 29 is tilted and multiple guide plates 29 are evenly arranged along the outer wall of the carrier plate 30. When the coolant flows inside the connecting tube 13, the water flow impacts the guide plate 29 to control the rotation of the carrier plate 30.

[0072] A sliding rod 33 is fixedly installed on the outer wall of the top pressure shaft 31, and a sliding groove for the sliding rod 33 to slide is opened at the center position of the axial end of the supporting plate 30. The rotation of the supporting plate 30 drives the top pressure shaft 31 to rotate through the sliding rod 33, thereby controlling the reciprocating sliding of the top pressure shaft 31 to achieve self-cleaning of the filter layer 17.

[0073] As a preferred embodiment of the present invention, a liquid inlet pipe 25 and a liquid discharge pipe 26 are fixedly mounted on the outer wall of the connecting tube 13 , wherein the liquid inlet pipe 25 and the liquid discharge pipe 26 are made of elastic material.

[0074] Valve balls 16 are provided at both ends of the connecting tube 13 , and the two valve balls 16 are rotated to control the conduction and closing of the inner cavity of the connecting tube 13 .

[0075] The outer wall of the connecting tube 13 is provided with a parallel hinged rod 10, and the outer wall of the valve ball 16 is fixedly installed with a pin shaft connected to the parallel hinged rod 10. The two valve balls 16 are controlled to rotate by the parallel hinged rod 10, wherein the parallel hinged rod 10 is two straight plates parallel to each other, and another set of straight plates are rotatably installed at both ends and the middle part of the straight plate through the pin shaft. The straight plates at both ends are connected to the two valve balls 16 and rotate along the middle part of the middle straight plate, thereby controlling the synchronous rotation of the two valve balls 16 to improve the operating efficiency.

[0076] The drain pipe 26 is located between the filter layer 17 and one of the valve balls 16, and the inlet pipe 25 is located between the filter layer 17 and the other valve ball 16. After the two valve balls 16 are closed, a pressure difference is generated at both ends of the inlet pipe 25 and the drain pipe 26, thereby controlling the reverse flow of coolant in the area between the two valve balls 16. At this time, the filter layer 17 is further cleaned by reverse flushing of the coolant, thereby preventing impurities from clogging the filter layer 17.

[0077] A control pump 14 is fixedly mounted on the inner wall of the mounting box 6 , the output end of the control pump 14 is connected to the drain pipe 26 , the input end of the control pump 14 is connected to the inlet pipe 25 , and the control pump 14 is a common gear pump used to provide power for backwashing the filter layer 17 with coolant.

[0078] An extrusion cam 27 is fixedly mounted on the inner wall of the installation box 6. The extrusion cam 27 is located between the liquid inlet pipe 25 and the liquid discharge pipe 26. The extrusion cam 27 is rotated to squeeze the liquid inlet pipe 25 and the liquid discharge pipe 26, thereby controlling the flow aperture in the liquid inlet pipe 25 and the liquid discharge pipe 26 to become narrower during squeezing.

[0079] The output shaft of the built-in motor of the control pump 14 is fixedly installed with a transmission shaft 28, and the transmission shaft 28 is fixedly connected to the center position of the axial end of the extrusion cam 27. When the control pump 14 is working, the extrusion cam 27 is driven to rotate by the transmission shaft 28, and then the outer walls of the liquid inlet pipe 25 and the liquid discharge pipe 26 are reciprocated. During backflushing, the flow speed of the coolant is controlled to make the filter layer 17 shake, thereby further improving the efficiency of impurity shedding and separation.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
