Description

Technical Field

[0001] The present application relates to the field of cable trays, and in particular to a modular combined cable tray and an installation method thereof. Background Art

[0002] During the construction of rail transit systems such as subways, it is necessary to lay and install cables on the top of the tunnel to transmit power, signals and control commands to the subway trains during their subsequent operation.

[0003] In order to better support and fix the cables, it is usually necessary to install a cable tray on the top of the tunnel before laying the cables. The cables are then laid in the cable tray to support and fix the cables and reduce mechanical damage to the cables.

[0004] In the related art, the cable tray includes a trough frame and a buckle cover, wherein the buckle cover is buckled on the top of the trough frame to limit the subsequent dust from entering the trough frame. When installing the cable tray, it is necessary to first install a number of hangers on the top of the tunnel to support the cable tray, and then install and fix the cable tray on the hangers.

[0005] With regard to the above-mentioned related technologies, after the cables are installed on the cable tray, a large amount of heat will be generated during use due to their large number and high operating power. The groove cover and buckle cover of the cable tray form a relatively closed space, which is not conducive to the heat dissipation of the cables as a whole. Therefore, there is room for improvement. Summary of the invention

[0006] In order to improve the heat dissipation effect of the cable tray, the present application provides a modular cable tray, a tray auxiliary installation mechanism and a tray installation method.

[0007] The present application provides a modular cable tray, a tray installation mechanism and a tray installation method, which adopt the following technical solutions:

[0008] A modular combined cable tray comprises a cable tray body, wherein the cable tray body is spliced ​​together by a plurality of trough frame units, and the tops of the trough frame units are buckled with buckle covers; a plurality of heat dissipation holes are opened at the bottoms of the trough frame units, and a plurality of support rods are further arranged in the trough frame units, and the two ends of the support rods are respectively connected to the two opposite inner walls of the trough frame units, and a spacing is left between the support rods and the bottoms of the trough frame units; connecting trough members are arranged between adjacent trough frame units, and the adjacent ends of the adjacent trough frame units are embedded in the connecting trough members, and the two ends of the connecting trough members are respectively connected to the adjacent ends of the adjacent trough frame units through a plurality of bolts and nuts.

[0009] By adopting the above technical solution, when laying cables later, the cables can be overlapped on several support rods, and several support rods can be used to support the cables away from the bottom of the trough frame, so as to better dissipate heat when the cables in the trough frame unit are running. On the other hand, several support rods can be used to improve the overall strength of the trough frame unit and reduce the deformation and damage of the trough frame unit. Adjacent trough frame units are connected by connecting trough parts, so that the cable tray does not need to be made in one piece, which is convenient for the transportation and installation of the cable tray.

[0011] By adopting the above technical solution, when installing the trough frame unit later, after moving the trough frame unit to the installation position, the installation plate is fixed to the top of the tunnel by expansion bolts to complete the installation and fixation of the trough frame unit. Compared with the traditional method of installing the hanger first and then installing the trough frame unit, the overall construction steps are simplified and the height error between adjacent hangers is effectively reduced when the hanger is first constructed, which affects the subsequent installation of the trough frame unit.

[0012] Preferably, a support tube is coaxially rotatably sleeved on the support rod.

[0013] By adopting the above technical solution, when the cable is subsequently pulled into the trough unit, the friction between the cable and the support rod can be reduced through the support tube, which facilitates the laying of the cable in the trough unit of the cable tray.

[0014] Preferably, a rubber strip is further provided between the transverse rod and the slot frame unit, and the top and bottom sides of the rubber strip are respectively in contact with the slot frame unit and the support rod.

[0015] By adopting the above technical solution, the rubber strips can be used for shock absorption and buffering, thereby reducing the sliding or displacement of the slot frame unit caused by vibration, making the cables in the slot frame unit less likely to be damaged.

[0017] By adopting the above technical solution, when installing the slot frame unit later, after the bracket is slidably matched to the track of the tunnel through the sliding part, the bracket is slid along the track through the sliding part until the main clamping part at the top of the bracket is located below the installation position of the slot frame unit to be installed, the slot frame unit to be installed is placed on the main clamping part and the slot frame unit is clamped by the main clamping part, and then the main clamping part is moved up until the slot frame unit is moved to the installation position, and finally the mounting plate at the top of the slot frame unit hanger is fixed to the top of the tunnel through the expansion bolts to achieve the installation and fixation of the slot frame unit. The slot frame unit is clamped by the main clamping part, and the slot frame unit is temporarily positioned by the main clamping part to limit the displacement of the slot frame unit during the installation process, so as to facilitate the subsequent fixing of the mounting plate on the hanger to the top of the tunnel through the expansion bolts; at the same time, the bottom of the bracket can be slidably connected to the track inside the tunnel through the sliding part, so as to facilitate the quick and convenient movement of the bracket to the installation position below different slot frame units during the subsequent installation and construction process.
