Technical Field
[0001] This invention relates to a large-scale cable tray splicing seismic-resistant bracket and its usage method. Background Technology
[0002] To better protect indoor and outdoor cables, cable trays are typically used for protection. Cable trays are available in various types, including trough, tray, ladder, and mesh types. Their structure generally consists of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or attached to various building structures and pipe rack supports. They should be characterized by simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance.
[0003] To better protect the internal cables, when installing cable trays, brackets are usually used to assist in shock absorption to buffer the impact on the cable trays from external forces. During installation, the fixing bracket is installed first, and then four buffer rods are installed on the left and right sides of the fixing bracket to complete the installation.
[0004] The above-mentioned device has the following disadvantages when in use: the overall installation area required is large, which is quite limiting, and the overall buffer structure is relatively simple and cannot perform corresponding buffering actions according to the external intensity. Therefore, there is an urgent need for a large cable tray splicing seismic bracket. Summary of the Invention

[0008] Preferably, a frustum block is provided at one end of the connecting rod inside the seismic chamber, and a large spring block is provided at the same end as the nut inside the seismic chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. The entire device is installed using a double-connecting frame method. The entire device is connected by a series rod wrapped with vibration isolation pads. While having a good seismic structure, it has a small overall footprint and relatively few limitations.

[0025] To address the limitations of existing installation methods and the relatively singular nature of seismic-resistant structures, this invention provides a large-scale cable tray splicing seismic-resistant bracket and its usage method. The technical solution of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described invention is only a part of this invention, not all of it. Based on the invention described herein, all other inventions obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.
[0026] Please see Figure 1-6 The present invention provides a large cable tray splicing seismic support bracket, including a bracket 1. Both the left and right seismic ends of the bracket 1 are provided with seismic chambers 2 that can resist seismic waves in stages. The upper surface of the bracket 1 is symmetrically provided with connecting frames 8. The upper surface of the connecting frames 8 is provided with fixed chambers 10 that can be connected to the wall and can isolate vibration.
[0027] Furthermore, the seismic chamber 2 is composed of a connecting rod 3, a frustum block 4, a large spring block 5, a friction block 6, and a nut 7. The friction block 6 is installed inside the seismic chamber 2, and the nut 7 is installed inside the seismic chamber 2. The friction block 6 is wrapped around the surface of the nut 7, and the threaded end of the nut 7 is provided with a connecting rod 3. By rotating the nut 7 and generating friction with the friction block 6, the vibration is converted into heat energy for consumption.
[0028] Furthermore, a frustum block 4 is provided at one end of the connecting rod 3 inside the seismic chamber 2, and a large spring block 5 is provided at the same end as the nut 7 inside the seismic chamber 2; the vibration is converted into overcoming elastic potential energy and consumed by the large spring block 5 by the frustum block 4 pressing the large spring block 5.
[0029] Furthermore, the fixed chamber 10 is composed of a buffer block 11, a compression block 12 and a locking block 13. A base 9 is provided on the upper surface of the connecting frame 8, and the fixed chambers 10 are symmetrically arranged on the surface of the base 9. The connection between the device and the wall is completed through the fixed chambers 10.
[0030] Furthermore, a buffer block 11 is provided inside the fixed chamber 10, a compression block 12 is provided on the lower surface of the buffer block 11, and a locking block 13 is provided on the lower surface of the compression block 12; the vibration drives the buffer block 11 to move inside the fixed chamber 10, and finally converts the vibration into heat energy consumption.
[0031] Furthermore, a fixing block 14 is provided on the surface of the connecting frame 8, and a wrapping pad 17 is wrapped around the surface of the fixing block 14; the wrapping pad 17 reduces the transmission of vibration.
[0032] Furthermore, the fixing block 14 is connected to the connecting rod 3 via a series rod 15, and the interfaces of the series rod 15 with the fixing block 14 and the connecting rod 3 are all covered with vibration isolation pads 16; the connecting rod 3 is connected to the fixing block 14 via the series rod 15, and the vibration isolation pads 16 reduce the transmission of vibration.
[0033] Furthermore, the connecting rod 3 is threaded inside the shock-resistant chamber 2; through the thread, the nut 7 rotates when the connecting rod 3 moves.
[0034] Furthermore, the bracket 1 is symmetrically provided with movable compartments 21. The upper surface of the movable compartments 21 is provided with protruding blocks 18 arranged in a linear array. The movable compartments 21 are provided with locking rods 19. The locking rods 19 and the protruding blocks 18 are respectively provided with plug-in blocks 20. By sliding the two locking rods 19 to reach the designated location, the bolts pass through the locking rods 19 and are finally connected to the large cable tray. During the connection process, the bolts will drive the plug-in blocks 20 on the surface of the locking rods 19 to insert into the protruding blocks 18 to lock the position of the locking rods 19, thereby completing the connection.
[0035] The aforementioned large-scale cable tray splicing seismic support includes the following steps:
[0036] Step A, Assembly: When installing with a large cable tray, slide the two locking rods 19 to the designated location, and then pass the bolts through the locking rods 19 to finally connect with the large cable tray. During the connection process, the bolts will drive the plug-in block 20 on the surface of the locking rod 19 to insert into the protruding block 18 to lock the position of the locking rod 19, thereby completing the connection.
[0037] Step B, Installation: Attach the base 9 to the wall surface, and finally connect it to the wall by passing the expansion screw through the fixing chamber 10. As the expansion screw continuously enters the wall, its lower end will continuously squeeze the locking block 13, and finally squeeze the buffer block 11 to the upper surface of the buffer block 11 through the squeezing block 12.
[0038] Step C, Earthquake Resistance of the Wall: When the upper wall vibrates, it will be transmitted inward through the fixed chamber 10 immediately. The buffer block 11 inside the fixed chamber 10 will move inside. At this time, the vibration will be converted into heat energy and work done to overcome elastic potential energy. The remaining vibration will be transmitted along the connecting frame 8 to the surface of the fixed block 14. The surface of the fixed block 14 is covered with a wrapping pad 17, and a vibration isolation pad 16 is also wrapped on the contact side between the connecting rod 15 and the fixed block 14. Its load is a single layer load, which can reduce the natural frequency and thus achieve the vibration isolation effect.
[0039] Step D, seismic resistance of the cable tray section: When the cable tray section vibrates, the vibration is transmitted to the seismic chamber 2 through the bracket 1. If the vibration is small, it will drive the connecting rod 3 to move up and down in the seismic chamber 2. During the movement, the nut 7 will rotate under the action of the thread. During the rotation, the nut 7 and the friction block 6 will come into contact with each other and generate friction, converting the vibration into heat energy consumption. If the vibration is large, the connecting rod 3 will move a longer distance. At this time, the frustum block 4 on the connecting rod 3 will come into contact with the large spring block 5, converting the excess vibration into the action of overcoming elastic potential energy, thereby buffering and resisting the seismic.
[0040] The present invention provides a large-scale cable tray splicing seismic-resistant bracket and its method of use, which has the following advantages:
[0041] 1. The entire device is installed using a double connecting frame 8 method. The entire device is connected by a series rod 15 wrapped with vibration isolation pads 16. While having a good seismic structure, it has a small overall footprint and relatively few limitations.
[0042] 2. The entire device adopts a segmented and step-by-step vibration isolation method for seismic resistance. Seismic-resistant structures are set at each possible source of vibration to perform segmented seismic resistance. At the series connection, aftershocks are isolated by vibration isolation pads 16 and wrapping pads 17, which reduces the large vibrations caused by the mixing of multiple vibration sources. Step-by-step vibration isolation uses different seismic resistance methods for different vibration intensities, which is more sensitive and stronger.
[0043] Although the invention has been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these inventions without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
