Description

Technical Field

[0001] This utility model relates to the field of cable installation equipment, and in particular to a high-strength modular stainless steel cable tray. 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] The installation of cable trays needs to be carried out according to the specific route of the line. During the construction process, the route of the line is not always straight. Therefore, when the line bends, the corresponding cable trays also need to be bent accordingly. When cable trays need to be bent, they are usually customized before construction, or ordinary cable trays are cut and welded on site to complete the bending. However, in some construction environments, no-fire operation is required, which makes it impossible to cut and weld the cable trays. Utility Model Content

[0027] Example 1

[0028] Reference Figures 1 to 6This embodiment provides a high-strength modular stainless steel cable tray, including a cable tray 100. The cable tray 100 is composed of several triangular modules 200. Each triangular module 200 includes a frame 201 and a connecting pin 202. The frame 201 is generally L-shaped, and the base of the frame 201 is an isosceles triangle. Several sets of frames 201 are staggered. The connecting pin 202 is located at the top corner of the frame 201. Several sets of frames 201 are connected and cooperate through the connecting pin 202.

[0029] Both ends of the outer wall of the frame 201 are provided with hanging ears 201a, and the heights of the hanging ears 201a at both ends of the outer wall are different.

[0030] A through hole 201b is provided at the top corner of the frame 201 and at the top of the outer wall of the lug 201a. The through hole 201b is sleeved with the connecting pin 202. The connecting pin 202 at the top corner of the frame 201 in a single group is connected to the through holes 201b of the other two adjacent triangular modules 200 to complete the connection and fixation of several groups of frames 201.

[0031] The triangular module 200 includes a bottom pin 202a and a threaded pin 202b. The bottom of the threaded pin 202b is provided with a threaded bolt 202a-1. The top of both the bottom pin 202a and the threaded pin 202b is provided with a threaded groove 202a-2. The single set of connecting pins 202 includes a single bottom pin 202a and three sets of threaded pins 202b that are threaded together. The bottommost threaded pin 202b is threadedly connected to the threaded groove 202a-2 at the top of the bottom pin 202a.

[0032] The length of the threaded groove 202a-2 is greater than the depth of the threaded bolt 202a-1; when the bottom pin 202a is connected to the threaded pin 202b or different threaded pins 202b, after the threaded bolt 202a-1 is completely inserted into the threaded groove 202a-2, a part is still exposed outside, and this part is sleeved with the through hole 201b.

[0033] The bottom pin 202a is fixedly connected to the bottom corner of the frame 201 by screws.

[0034] A connecting bolt 202c is sleeved between two adjacent threaded pins 202b in a single group. Several sets of through holes are opened through the outer wall of the threaded pin 202b. By placing the bolt into the through holes of the two sets of connecting bolts 202c, the minimum limit distance between the two sets of connecting pins 202 is determined, so as to complete the fixation of the cable tray 100 bending.

[0035] Working principle: When it is necessary to bend the cable tray 100, after determining the part of the cable tray 100 that needs to be bent, the connecting pin 202 of the triangular module 200 is removed to separate it from the adjacent frame 201. The frame 201 is then removed, and the connecting pin 202 is reassembled and restored so that it is in a sleeved state with the adjacent frame 201. Then, the connection pin 202 is rotated as the center, and the outer edges of the two adjacent frames 201 are kept parallel. Finally, the bolt is inserted into the through hole of the connecting bolt 202c and fixed to complete the fixing of the cable tray 100 after bending.
