Description

Technical Field

[0001] The utility model relates to the technical field of structural energy dissipation and shock absorption, and specifically refers to a novel energy dissipation and limit device with a rubber and a steel baffle plate arranged inside a funnel-shaped steel cylinder. Background Technique

[0002] As an effective shock absorption control technology, damping energy dissipation devices have been widely used in structural engineering. Setting damping energy dissipation devices at key connection parts of structures can increase the damping of the structures, extend the natural vibration period of the structures, and weaken the seismic response of the structures. Currently, oil dampers, metal dampers, shape memory alloys and other damping energy dissipation devices are widely used in structures and can play an energy dissipation role, but there are still many deficiencies. For example, oil dampers are prone to oil leakage, which affects the service life; metal dampers are prone to fatigue and the deformation is difficult to recover; shape memory alloys are costly and difficult to use on a large scale.

[0003] The friction generated when rubber and steel slide relative to each other can dissipate energy, but the sliding displacement is difficult to control. A novel energy dissipation and limit device with a rubber and a steel baffle plate arranged inside a funnel-shaped steel cylinder has the functions of adjusting the friction energy dissipation ability and controlling the sliding displacement, and has the advantages of low cost, long service life, easy installation and replacement.

The upper flange of the funnel-shaped steel cylinder I is connected with the flange of the force transmission sleeve, and the lower flange of the funnel-shaped steel cylinder I is connected with the lower flange of the funnel-shaped steel cylinder II. Finally, the ball hinge II is pushed to place the internal rubber at the central position of the whole funnel-shaped steel cylinder I and the funnel-shaped steel cylinder II, thus forming a novel energy dissipation and limit device with a rubber and a steel baffle plate arranged inside a funnel-shaped steel cylinder.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] As Figure 1 and Figure 2 shown, a new energy-dissipating limit device with a rubber and steel baffle inside a funnel-shaped steel cylinder mainly consists of a ball hinge one (1), a force transfer sleeve (2), a funnel-shaped steel cylinder one (6), an upper baffle (10), a built-in rubber (12), a lower baffle (13), a high-strength bolt one (9), a high-strength bolt two (16), a steel rod (20), a funnel-shaped steel cylinder two (18), and a ball hinge two (23).

[0028] The upper flanges (5 and 19) and lower flanges (7 and 17) are respectively connected to the upper and lower sides of the funnel-shaped steel cylinder one (6) and the funnel-shaped steel cylinder two (18). A spherical hinge one (1) is installed on one side of the force transfer sleeve (2), and a spherical hinge two (23) is installed on one side of the steel rod (20).

[0029] The upper thread (21) and the lower thread (22) are provided on the steel rod (20). A circular hole (11) is provided in the center of the upper baffle (10), a circular hole (14) is provided in the center of the built-in rubber (12), a circular hole (15) is provided in the center of the lower baffle (13), and a through-hole is provided at the central position of the upper flange (5) of the funnel-shaped steel cylinder one and the upper flange (19) of the funnel-shaped steel cylinder two.

[0030] The inner diameters of the circular hole (11) of the upper baffle, the circular hole (14) of the built-in rubber, the circular hole (15) of the lower baffle, the force transfer sleeve (2), the through-hole of the upper flange (5) of the funnel-shaped steel cylinder one and the through-hole of the upper flange (19) of the funnel-shaped steel cylinder two are all larger than the diameter of the steel rod (20), so that the steel rod (20) can pass through.

[0031] Chamfers are provided at the edge positions of the upper baffle (10) and the lower baffle (13), and the slopes are the same as the conical angles of the funnel-shaped steel cylinder one (6) and the funnel-shaped steel cylinder two (18).

[0032] The steel rod (20) is passed through the central circular hole of the upper flange (19) of the funnel-shaped steel cylinder two from the side of the upper thread (21) of the steel rod, so that the spherical hinge two (23) connected to the steel rod (20) is located outside the funnel-shaped steel cylinder two (18).

[0033] A high-strength bolt two (16) is installed at the lower thread (22) of the steel rod. The lower baffle (13), the built-in rubber (12) and the upper baffle (10) are inserted into the steel rod (20), so that the built-in rubber (12) is installed inside the funnel-shaped steel cylinder two (18). The left side of the built-in rubber (12) is flush with the edge of the lower flange (17) of the funnel-shaped steel cylinder two. A high-strength bolt one (9) is installed at the upper thread (21) of the steel rod and tightened to the design torque, so that the laterally expanding built-in rubber (12) is in close contact with the inner wall of the funnel-shaped steel cylinder two (18).

[0034] The upper flange (5) of the funnel-shaped steel cylinder one is connected to the flange of the force transfer sleeve (3) by using the force transfer sleeve bolt (4). The lower flange (7) of the funnel-shaped steel cylinder one and the lower flange (17) of the funnel-shaped steel cylinder two are connected by using the funnel-shaped steel cylinder bolt (8), so that a part of the side of the upper thread (21) of the steel rod penetrates into the force transfer sleeve (2). At this time, the state is as Figure 3 shown.

[0035] Push the spherical hinge two (23) to place the built-in rubber (12) at the central position of the whole of the funnel-shaped steel cylinder one (6) and the funnel-shaped steel cylinder two (18). At this time, the state is as Figure 4As shown, a new energy-dissipating and displacement-limiting device is formed with a rubber and a steel baffle plate placed inside a funnel-shaped steel cylinder.

[0036] Under the action of an axial force, by pushing and pulling ball hinge one (1) and ball hinge two (23), the internal rubber (12) slides and dissipates energy on the inner walls of funnel-shaped steel cylinder one (6) and funnel-shaped steel cylinder two (18).

[0037] The displacements of the upper baffle plate (10) and the lower baffle plate (13) are limited by the conical necks of funnel-shaped steel cylinder one (6) and funnel-shaped steel cylinder two (18), thereby realizing the displacement-limiting function. When the upper baffle plate (10) slides to the leftmost side of the inner wall of the straight cylinder part of funnel-shaped steel cylinder one (6), the conical neck of funnel-shaped steel cylinder one (6) fits with the chamfer of the upper baffle plate (10), converting to the left-side displacement-limiting state. At this time, the left side of the steel rod (20) is inside the force-transferring sleeve (2), as Figure 5 shown.

[0038] When the lower baffle plate (13) slides to the rightmost side of the inner wall of the straight cylinder part of funnel-shaped steel cylinder two (18), the conical neck of funnel-shaped steel cylinder two (18) fits with the chamfer of the lower baffle plate (13), converting to the right-side displacement-limiting state, as Figure 6 shown.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be within the protection scope of the present invention.
