[0002] A rigid structure system composed of straight sections, elbows, tees, cross components, brackets, and hangers of trough type, tray type or ladder type, which closely supports cables, is called a cable tray. Cable trays are divided into structures such as trough type, tray type, ladder type and grid type, and are composed of brackets, brackets and installation accessories, etc. The cable tray in the building can be erected independently or attached to various building and pipe gallery brackets. It should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized. For the cable tray installed outdoors on the building, if it is near the sea or belongs to a corrosion area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion and high impact resistance. During the use of the cable tray, the cable tray needs to be supported. In order to ensure the normal use of the cable tray, the use frequency of the support anti-seismic device is also increasing.

U-shaped frames are fixed on the upper surface of the placement plate and near its left and right sides. A fixing mechanism is provided on the upper surface of the placement plate. In this two-way support anti-seismic device for a cable tray, a buffer mechanism is provided. Through the mutual cooperation between the structures in the buffer mechanism, the influence of external forces and external factors on the support anti-seismic device can be effectively reduced, ensuring the stability of the cable tray in the support anti-seismic device, preventing the cable tray from being damaged during use, and thus playing a role in protecting the cable.

The existing technology is to set a buffer mechanism in the support anti-seismic device for treatment. However, there will still be a situation where the buffer effect is not ideal, the anti-seismic effect is average, only single-stage damping can be carried out, and multi-stage damping cannot be achieved, which leads to the problem of reduced utilization efficiency of the anti-seismic support mechanism.

Specific implementation mode

[0024] The following further describes the present utility model in detail with reference to the embodiments:

[0025] Embodiment 1

[0026] As Figures 1-4 shown, the present utility model provides a cable bridge earthquake-resistant support structure for power engineering, including an earthquake-resistant device 1, a support base 2 fixedly installed on the upper surface of the earthquake-resistant device 1, and an earthquake-resistant seat 3 arranged above the surface of the support base 2.

A bridge frame clamping plate 42 is fixedly installed on the top surface of the pressing block 41. A pressure plate is fixedly installed at the bottom of the pressing block 41. The pressure plate is located inside the earthquake-resistant seat 3, and both ends of the pressure plate are slidably connected to the inner wall surface of the earthquake-resistant seat 3. A rubber block 43 and a positioning rod 44 are installed on the lower surface of the pressure plate. The positioning rod 44 is located on one side of the rubber block 43, and a buffer spring 45 is sleeved on the surface of the positioning rod 44. By setting the bridge frame clamping plate 42 to clamp and limit the bridge frame, and then by setting the pressing block 41, the generated earthquake force presses it down, thereby driving the pressure plate installed at its bottom end to press down. During the pressing process, the rubber block 43 contacts the bottom of the inner cavity of the earthquake-resistant seat 3 and is compressed. Then, through the cooperation of the positioning rod 44 and the buffer spring 45, the force is buffered through compression to improve the buffer effect.

[0027] Embodiment 2

[0028] As Figures 1-4As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the primary buffer unit includes a seismic arc plate 51 fixedly installed on the lower surface of the seismic seat 3 and the upper surface of the seismic device 1. The inner surface of the surface of the seismic arc plate 51 is movably connected with a connecting rod 52. A damping spring 53 is fixedly installed on the surface of the connecting rod 52. Elastic components 54 are fixedly installed on both sides of the seismic arc plate 51. Rubber vertical rings 55 are fixedly installed on the upper and lower surfaces of the elastic components 54. The outer surface of the rubber vertical rings 55 is fixedly connected to the bottom of the seismic seat 3. By setting the seismic arc plate 51, pressure is exerted on it by the seismic seat 3 and it moves downward. During the downward movement, through the cooperation of the connecting rod 52 and the damping spring 53, by compressing the damping spring 53, buffering is carried out. At the same time, affected by the pressure, the rubber vertical rings 55 are deformed, and using their own elastic force, in cooperation with the elastic components 54, the pressure received is buffered. By improving the buffering effect, the seismic resistance effect of the device is further improved.

[0029] Embodiment 3

[0030] As Figures 1-4 As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the secondary buffer unit includes a sleeve rod 61 fixedly connected to the bottom of the seismic seat 3. The sleeve rod 61 is movably connected inside the seismic device 1. A telescopic rod 62 is slidably connected inside the sleeve rod 61. And a buffer step block 63 is fixedly installed on the outer surface of the sleeve rod 61. A connecting plate 64 is arranged on one side of the buffer step block 63. The connecting plate 64 is located inside the seismic device 1. A buffer component 65 is fixedly connected to one side surface of the connecting plate 64. The outer surface of the buffer component 65 is attached to the bottom surface of the buffer step block 63. An elastic arc member 66 is fixedly installed on the other side surface of the connecting plate 64. Buffer sleeves 67 are arranged at both ends of the elastic arc member 66. A buffer rod body 68 is fixedly connected inside the buffer sleeves 67. The inside of the elastic arc member 66 is slidably connected to the outer surface of the buffer rod body 68. Springs are fixedly installed on the surfaces of the telescopic rod 62 and the buffer rod body 68. The seismic seat 3 drives the sleeve rod 61 to slide on the surface of the telescopic rod 62. During the movement, the springs installed on the surface of the telescopic rod 62 are compressed or stretched for buffering. At the same time, the sleeve rod 61 drives the buffer step block 63 to contact and squeeze the buffer component 65, thereby driving the connecting plate 64 to move and squeeze the elastic arc member 66. The stressed elastic arc member 66 deforms and slides on the surface of the buffer rod body 68 inside the buffer sleeve 67, and is buffered under the action of the spring on the surface of the buffer rod body 68 and its own elastic force. The direction of the received seismic force is changed from the up-down direction to the left-right direction. Through multi-stage buffering, it is beneficial to improve the buffering effect.

[0031] Next, the working principle of the seismic support structure for the cable tray in the power project will be specifically described.

[0032] As Figures 1-4 shown, first, by setting the seismic arc plate 51, pressure is exerted on it by the seismic base 3 and it moves downward. During the downward movement, through the cooperation of the connecting rod 52 and the damping spring 53, buffering is carried out by compressing the damping spring 53. At the same time, affected by the pressure, the rubber vertical ring 55 deforms and uses its own elastic force to cooperate with the elastic component 54 to buffer the pressure received. By improving the buffering effect, secondly, the sleeve rod 61 is driven by the seismic base 3 to slide on the surface of the telescopic rod 62. During the movement, the spring installed on the surface of the telescopic rod 62 is compressed or stretched for buffering. At the same time, the sleeve rod 61 drives the buffer ladder block 63 to contact and squeeze the buffer component 65, thereby driving the connecting plate 64 to move and squeeze the elastic arc member 66. The elastic arc member 66 under pressure deforms and slides on the surface of the buffer rod body 68 inside the buffer sleeve 67, and is buffered under the action of the surface spring of the buffer rod body 68 and its own elastic force. The direction of the seismic force received is changed from the up and down direction to the left and right direction. Through multi-stage buffering, it is beneficial to improve the buffering effect.

[0033] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
