Description

Technical Field

[0001] The invention relates to the technical field of shock absorption of electromechanical equipment in subway construction, in particular to an anti-seismic support frame for subway construction. Background Art

[0002] During subway construction and subsequent operation, electromechanical equipment often needs to be installed on specific seismic support frames, which are used to buffer various vibrations generated during construction and operation to ensure or extend the service life of the electromechanical equipment.

[0003] Existing seismic support frames usually include a vertical seismic mechanism for buffering vertical vibrations and a transverse seismic mechanism for buffering transverse (horizontal) vibrations. The vertical seismic mechanism has a relatively simple structure, usually a retractable column and a vertically distributed shock-absorbing spring at the telescopic position of the column. The transverse seismic mechanism (such as a mechatronic seismic support device for subway construction disclosed in 202310346807.X) usually includes an outer frame fixed to the vertical seismic mechanism, a middle frame slidingly arranged in the outer frame along the plane X-axis direction, and an inner frame slidingly arranged in the middle frame along the plane Y-axis direction. The inner frame is used to carry electromechanical equipment, and transverse shock-absorbing springs are respectively arranged on the sliding strokes of the middle frame and the inner frame, so that the vibrations from two directions are correspondingly buffered by two sets of transversely distributed shock-absorbing springs perpendicular to each other. The transverse seismic mechanism is not only complex in structure, but also in the construction and subsequent operation of the subway, the transverse vibrations often cannot be strictly transmitted in the corresponding X or Y axis direction, which makes it difficult for such seismic support frames to exert a stable and effective seismic effect. Summary of the invention

[0004] The present invention aims to provide a seismic-resistant support frame for subway construction, so as to further improve the seismic-resistant effect of electromechanical equipment during subway construction or operation.

[0005] In order to solve the above technical problems, the specific solution adopted by the present invention is: an anti-seismic support frame for subway construction, including a vertical shock-absorbing frame and a transverse shock-absorbing frame arranged on the vertical shock-absorbing frame, the transverse shock-absorbing frame including a shock-absorbing frame and a shock-absorbing plate, the shock-absorbing frame and the shock-absorbing plate are both circular, the shock-absorbing frame is connected to the vertical shock-absorbing frame, the shock-absorbing plate is used to carry electromechanical equipment for construction and is located in the shock-absorbing frame, and a plurality of radial shock-absorbing springs are arranged between the outer edge of the shock-absorbing plate and the inner edge of the shock-absorbing frame.

[0006] Preferably, a concentrically distributed outer sliding ring is provided in the shock absorbing frame, and the outer end of the radial shock absorbing spring is fixed on an outer sliding block slidably arranged on the outer sliding ring.

[0007] Preferably, a plurality of outer fixing blocks for fixing the outer sliding ring are provided at intervals on the inner edge of the shock absorbing frame.

[0008] Preferably, the outer fixing block corresponds to the outer sliding block at intervals one to one, and an outer circumferential shock-absorbing spring is sleeved on the outer sliding ring between the corresponding outer fixing block and the outer sliding block, and the ends of the outer circumferential shock-absorbing spring are respectively fixedly connected to the outer fixing block and the outer sliding block.

[0009] Preferably, the number of outer sliding blocks provided with outer circumferential damping springs accounts for 1 / 5-1 / 4 of the total number of outer sliding blocks.

[0010] Preferably, two adjacent outer circumferential damping springs are respectively located on both sides of the corresponding outer sliding block in the circumferential direction.

[0011] Preferably, a concentrically distributed inner sliding ring is disposed outside the shock absorbing disk, and the inner end of the radial shock absorbing spring is fixed on an inner sliding block slidably disposed on the inner sliding ring.

[0012] Preferably, a plurality of inner fixed blocks for fixing the inner sliding ring are provided at intervals on the outer edge of the shock absorbing disk, and the inner fixed blocks and the inner sliding block correspond to each other in intervals. An inner circumferential shock absorbing spring is sleeved on the inner sliding ring at a position between the corresponding inner fixed blocks and the inner sliding block, and the ends of the inner circumferential shock absorbing spring are fixedly connected to the inner fixed block and the inner sliding block respectively.

[0013] Preferably, a support plate for supporting the shock absorbing disc is provided at the bottom of the shock absorbing frame.

[0014] Preferably, a plurality of mounting holes are provided at intervals on the bottom of the shock absorbing plate, and rolling balls are provided in the mounting holes for rolling cooperation with the support plate.

[0015] The transverse shock-absorbing frame in the present invention only includes a shock-absorbing frame and a shock-absorbing plate located in the shock-absorbing frame. The shock-absorbing frame is arranged on the vertical shock-absorbing frame. The shock-absorbing plate is used to carry electromechanical equipment. Both the shock-absorbing frame and the shock-absorbing plate are circular. The inner edge of the shock-absorbing frame and the outer edge of the shock-absorbing plate are connected by a plurality of radial shock-absorbing springs. The structure is simple and easy to implement. Moreover, since the radial shock-absorbing springs are evenly spaced along the inner edge of the shock-absorbing frame and the outer edge of the shock-absorbing plate, after the vibration in any transverse direction is transmitted to the vibration plate and the electromechanical equipment thereon, the radial shock-absorbing springs parallel to or nearly parallel to the vibration direction can be used to buffer the vibration through tensile deformation or compression deformation. Therefore, the present invention can buffer the vibration in all directions, thereby improving the anti-seismic effect of the electromechanical equipment during subway construction or operation.

[0016] In a preferred embodiment of the present invention, the ends of the radial shock-absorbing springs are respectively fixed on an outer slider and an inner slider, and the outer slider and the inner slider are respectively fixed on an outer sliding ring and an inner sliding ring slidably arranged on the shock-absorbing frame and the shock-absorbing disk. Therefore, during the lateral vibration transmission process, the ends of each radial shock-absorbing spring having a larger angle with the vibration direction can slide along the corresponding outer sliding ring and inner sliding ring, thereby avoiding the distortion and deformation failure of the shock-absorbing spring and the sliding column after being subjected to vertical vibration in the existing patent technology involved in the background technology, thereby greatly improving the service life of the present invention and ensuring the shock-absorbing effect of the present invention.

[0017] Furthermore, on the above-mentioned outer sliding ring and inner sliding ring, an outer circumferential shock-absorbing spring and an inner circumferential shock-absorbing spring are also sleeved at the position between the outer sliding block and the inner sliding block and the corresponding outer fixing block and inner fixing block for fixing the outer sliding block and the inner sliding block. On the one hand, the shock-absorbing plate can be reset by the outer circumferential shock-absorbing spring and the inner circumferential shock-absorbing spring. On the other hand, when the shock-absorbing plate and the electromechanical equipment thereon are subjected to torsional vibration in the lateral direction, the tensile deformation or compression deformation of the outer circumferential shock-absorbing spring and the inner circumferential shock-absorbing spring can be used for buffering. Therefore, the present invention can not only buffer linear vibration in the lateral direction, but also buffer torsional vibration in the lateral direction, thereby further improving the anti-seismic effect of the present invention.

[0018] In addition, when the torsional vibration is transmitted to the shock absorbing plate and the electromechanical equipment thereon, due to the circular layout of the present invention, all of the above-mentioned outer circumferential shock absorbing springs and inner circumferential shock absorbing springs can simultaneously generate the tensile deformation or compression deformation required for buffering, thereby achieving a good anti-vibration effect without setting an excessive number of outer circumferential shock absorbing springs and inner circumferential shock absorbing springs, thereby saving the use of springs and reducing the performance requirements of a single outer circumferential shock absorbing spring and inner circumferential shock absorbing spring, making the present invention easy to process and manufacture and controlling costs.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is described below through three embodiments.

[0025] Example 1

[0026] The anti-seismic support frame for subway construction of this embodiment is similar to the conventional anti-seismic support frame in the prior art in that both include a vertical shock-absorbing frame for buffering vertical vibration and a transverse shock-absorbing frame for buffering transverse (horizontal) vibration. Different from the conventional anti-seismic support frame, this embodiment has a transverse shock-absorbing frame with a special structure to buffer vibration in any transverse direction, thereby achieving a better anti-seismic effect.

[0027] In order to achieve the above technical effects, Figure 1 As shown, the transverse shock absorbing frame body in this embodiment includes an annular shock absorbing frame 1 and a circular shock absorbing plate 3, wherein the shock absorbing frame 1 is fixed on the vertical shock absorbing frame (conventional technical means in this field, not shown in the figure), and the shock absorbing plate 3 is distributed in the shock absorbing frame 1 and is used to carry the electromechanical equipment that needs earthquake protection. Between the inner edge of the shock absorbing frame 1 and the outer edge of the shock absorbing plate 3, 16 radial shock absorbing springs 2 are evenly spaced, and the two ends of the radial shock absorbing springs 2 are fixedly connected to the shock absorbing frame 1 and the shock absorbing plate 3 respectively.

[0028] Based on the above structure, after the linear braking in any lateral direction is transmitted to the shock absorbing disc 3 and the electromechanical equipment thereon, the radial shock absorbing spring 2 parallel to or nearly parallel to the vibration direction can be stretched or compressed for buffering, thereby buffering the vibration in that direction. In addition, because the 16 radial shock absorbing springs 2 are evenly spaced and distributed along the circumference of the shock absorbing frame 1 and the shock absorbing disc 3, the present embodiment has a good shock absorbing and buffering effect for vibration in any lateral direction.

[0029] like Figure 2 As shown, the bottom of the shock absorbing frame 1 is also provided with a support plate 13, and the bottom of the shock absorbing disc 3 is provided with a mounting hole 15, in which a rolling ball 14 and a support spring 12 for pushing the lower edge of the rolling ball 14 out of the mounting hole 15 are provided, and the rolling ball 14 and the upper edge of the support plate 13 are rollingly matched, so that the shock absorbing disc 3 and the electromechanical equipment thereon can flexibly move under the action of vibration to stretch or compress the radial shock absorbing spring 2 at the corresponding position. At the same time, the support spring 12 is distributed vertically, which can also assist in strengthening the anti-seismic buffering effect of the vertical shock absorbing frame for vertical vibration.

[0030] Example 2

[0031] The main structure of this embodiment is the same as that of the first embodiment, except that the present embodiment can reduce the distortion and deformation of the radial damping spring 2 in the non-longitudinal direction, and increase the ability to resist torsional vibration that the first embodiment does not have, specifically:

[0032] like Figure 3 As shown, the inner end of the radial damping spring 2 in this embodiment is directly fixed to the outer edge of the damping plate 3, but its outer end is fixed to an outer slider 6. An outer sliding ring 7 is fixedly provided on the inner edge of the damping frame 1 through 16 outer fixing blocks 4 for sliding cooperation of all the outer sliders 6. Through the sliding cooperation between the outer slider 6 and the outer sliding ring 7, the end of each radial damping spring 2 with a larger angle to the vibration direction can slide along the corresponding outer sliding ring 7 during the lateral vibration transmission process, thereby avoiding the large distortion and deformation failure caused by the outer end of the radial damping spring 2 being directly fixed to the damping frame 1.

[0033] The outer fixing blocks 4 and the outer sliding blocks 6 are arranged in a one-to-one interval and correspondence, and an outer circumferential damping spring 5 is sleeved on the outer sliding ring 7 between the outer fixing blocks 4 and the outer sliding blocks 6, and the two ends of the outer circumferential damping spring 5 are respectively fixedly connected to the outer sliding blocks 6 and the outer fixing blocks 4. Through the outer circumferential damping spring 5, when the electromechanical equipment is subjected to torsional vibration in the lateral direction, the outer circumferential damping spring 5 can also be stretched or compressed to perform buffering, thereby enabling this embodiment to produce the ability to resist torsional vibration that the first embodiment does not have.

[0034] Example 3

[0035] On the basis of Example 2, in order to further prevent the inner end of the radial damping spring 2 from being pulled and damaged, and to further improve the ability to resist torsional vibration, as shown in FIG. Figure 4 As shown, in this embodiment, a concentrically distributed inner sliding ring 11 is fixed on the outer periphery of the shock absorbing disk 3 through a plurality of inner fixing blocks 8, 16 inner sliding blocks 10 are arranged on the inner sliding ring 11 and are fixedly connected to the inner end of the radial shock absorbing spring 2 through the inner sliding blocks 10, and at the same time, an inner circumferential shock absorbing spring 9 is also sleeved on the inner sliding ring 11 at a position between the corresponding inner fixing block 8 and the inner sliding block 10.

[0036] It should be noted that, after the torsional vibration is transmitted to the shock absorbing disc 3 and the electromechanical equipment thereon, all the outer circumferential shock absorbing springs 5 ​​and the inner circumferential shock absorbing springs 9 are stretched or compressed, so the present embodiment only needs to set 4 outer circumferential shock absorbing springs 5 ​​and 4 inner circumferential shock absorbing springs 9 to meet the torsional vibration resistance. At the same time, the four outer circumferential shock absorbing springs 5 ​​and the four inner circumferential shock absorbing springs 9 are located on both sides of the end of the same radial shock absorbing spring 2, so that after receiving the torsional vibration in the same direction, if one of the present embodiment produces a tensile deformation, the other one will inevitably be compressed, so that the shock absorbing disc 3 is not affected by the spring thrust or tension in a single direction, and the force is more uniform, which is conducive to achieving torsional vibration resistance and improving the service life.
