Description

Technical Field

[0001] This utility model relates to the field of cable installation equipment, and in particular to a lightweight load-bearing structure for stainless steel cable trays. Background Technology

[0002] Currently, cable trays are industrial products composed of supports, brackets, and installation accessories. Cable trays are categorized into trough-type, tray-type, ladder-type, and mesh-type structures. They can be installed independently or laid on various building and pipe rack supports, exhibiting characteristics such as simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance.

[0003] The following problems currently exist;

[0004] When installing existing cable trays, it is often necessary to install the threaded hangers and crossarms to the wall first, and then place the cable tray on the crossarm. In order to optimize the load-bearing capacity of the crossarm, it is often necessary to draw lines to center the cable tray during installation, so as to avoid uneven stress at both ends of the crossarm, which would shorten the service life of the load-bearing structure. After determining the position of the cable tray, the crossarm is fixed to the cable tray with fixing screws. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model.

[0026] Example 1

[0027] Reference Figures 1 to 7This embodiment provides a lightweight load-bearing structure for a stainless steel cable tray, including a crossarm 100, an inner groove 101 extending through the top of the crossarm 100, a cable tray 200 mounted on the top of the crossarm 100, and L-shaped connecting grooves 201 extending through both ends of the outer wall of the cable tray 200; and a connecting structure 300, which includes a connecting buckle 102, a connecting groove 201, and a fixing block 202. The connecting buckle 102 is rotatably connected inside the inner groove 101 of the crossarm 100, and the connecting groove 201 and the fixing block 202 are both installed on the inner wall of the cable tray 200.

[0028] Two sets of mirror-shaped connecting buckles 102 are rotatably connected in the inner groove 101 of a single crossarm 100. The overall shape of the connecting buckle 102 corresponds to the shape of the connecting groove 201. The connecting buckle 102 and the cable tray 200 cooperate with each other. The installation position of the cable tray 200 on the top of the crossarm 100 is determined by the cooperation of several sets of connecting buckles 102 and the cable tray 200.

[0029] The cable tray 200 has fixing blocks 202 installed at both ends of the inner wall of the single set of connecting grooves 201. Two sets of connecting rods 202a are fixedly connected to the outer wall of the fixing blocks 202, and springs 202b are fixedly connected to the outer wall of the fixing blocks 202. The other end of the springs 202b is fixedly connected to the slider 203. The slider 203 is inserted into the springs 202b and slides along the springs 202b. During installation, the connecting grooves 201 of the cable tray 200 are aligned with several sets of connecting buckles 102, and the cable tray 200 is lowered while maintaining a horizontal state. As the cable tray 200 is lowered, the bottom of the cable tray 200 contacts and presses against the connecting buckles 102. As the compression continues, the connecting buckle 102 rotates inside the inner groove 101 of the crossarm 100. The bottom of the connecting buckle 102 gradually falls into the connecting groove 201 and contacts the slider 203. Due to the continuous rotation of the connecting buckle 102, the connecting buckle 102 squeezes the two sets of sliders 203 around the connecting groove 201. The sliders 203 will then move along the connecting rod 202a until the connecting buckle 102 completely passes between the two sets of sliders 203. Then, the spring 202b provides elastic force and causes the sliders 203 to reverse and reset, thereby limiting the connecting buckle 102 and thus fixing the crossarm 100 to the cable tray 200.

[0030] The outer edge of the slider 203 and the top edge of the outer wall of the connecting buckle 102 are both smooth curved surfaces; this structure makes the extrusion displacement of the connecting buckle 102 and the slider 203 smoother.

[0031] The top two ends of the outer wall of the crossbeam 100 are provided with threaded holes; the crossbeam 100 is fixed to other entities through the cooperation of the threaded holes and the threaded hanger.

[0032] In some embodiments, the following may be adopted, including but not limited to: installing a spring at the connection between the connector 102 and the crossarm 100, or designing the center of gravity of the connector 102 as a whole, so that the end of the connector 102 is always tilted at 45° to 30° when it is not installed with the cable tray 200.

[0033] Working principle: The threaded hangers are fixed to other entities using expansion bolts, ensuring several threaded hangers are aligned in a straight line. Then, the crossbeam 100 is connected and fixed to the threaded hangers using bolts to complete the pre-installation of the cable tray 200. During installation, the cable tray 200 is lowered gradually while maintaining a horizontal position. As the cable tray 200 is lowered, the bottom of its outer wall contacts and presses against the end of the connecting buckle 102, causing the connecting buckle 102 to rotate. With the rotation of the connecting buckle 102… The end of the connecting buckle 102 is inserted into the connecting groove 201 of the cable tray 200 and contacts the slider 203. The end of the connecting buckle 102 presses against two adjacent sliders 203 and forces them to move along the connecting rod 202a until the connecting buckle 102 completely passes through the two adjacent sliders 203. Then, the spring 202b provides elastic force and causes the two sliders 203 to reset. The reset sliders 203 limit the end of the connecting buckle 102 and restrict its rotation to complete the installation of the crossarm 100 and the cable tray 200.
