Description

Technical Field

[0001] This document belongs to the technical field of cable trays, and specifically relates to a high-strength cable tray. Background Art

[0002] Cable trays are mainly used to lay computer cables, communication cables, thermocouple cables, and control cables of other highly sensitive systems, and are widely used in buildings such as large office buildings, financial commercial buildings, hotels, and stadiums.

[0003] In traditional steel cable trays, various cables are laid inside the cable tray in a messy and disorderly manner, making it difficult to classify and install cables for different purposes, resulting in poor usage effects. Moreover, the installation of existing cable trays is generally fixed through L-shaped hangers or U-shaped hangers. However, usually, such L-shaped or U-shaped hangers are simply structures formed by bending plates. Due to the limitations of the plates, the L-shaped or U-shaped hangers formed by sheet metal bending cannot achieve the layout of heavy cables. In order to increase the overall strength of the hangers, most of the hangers will add folding ribs during the bending process, or use combined hangers to add reinforcing ribs or connecting ribs on the outer and inner sides of the hangers to increase the overall strength of the cable tray.

[0004] However, when strengthening the cable tray in this form, the form of folding ribs will greatly increase the production difficulty of long-distance cable trays, while the form of adding reinforcing ribs and connecting ribs will greatly increase the weight of the cable tray, resulting in a decrease in the cable weight that the cable tray can carry. Summary of the Utility Model

[0005] To solve the above problems, this paper proposes a high-strength cable tray. The cable tray is a combined cable tray, which includes side profiles and a connecting chassis. The side profiles are arranged symmetrically left and right in a mirror image manner. The connecting chassis is embedded at the bottom between the symmetrical side profiles. The side profile includes a profile body, a profile cavity, an inner cavity rib plate, a bottom convex edge, and a combined chute. The shape of the profile body is a hollow I-shaped profile. A hollow and through profile cavity is vertically provided at the center inside the profile body. Convex edge hooks are provided on both sides of the top of the profile body. A combined chute protrudes downward from the bottom of the profile body. A bottom convex edge is longitudinally and parallelly provided below the inner surface of the profile body. Side plate connection holes are provided at both ends of both surfaces of the profile body. Bottom chassis assembly holes are provided at the bottom of both surfaces of the profile body. An inner cavity rib plate is provided inside the profile cavity. The connecting chassis is provided between the bottom surface of the bottom convex edge and the top surface of the combined chute. The connecting chassis is connected to the profile body through the bottom chassis assembly holes and locking bolts. The side plate connection holes are connected to the outside of the end of the profile body and the connecting side plate through locking bolts. By improving the originally thin bridge side plate into a profile-type side profile formed by high-strength stretching, the overall strength of the assembled bridge is achieved through the overall strength of the hollow profile. Moreover, a chassis can be provided at the bottom between the side plates, which is convenient for the overall assembly strength and convenient installation and connection.

[0006] The shape of the profile cavity is a vertical rectangular cavity. Inner cavity rib plates are symmetrically and parallelly provided on the upper and lower sides inside the profile cavity. The two ends of the inner cavity rib plates are longitudinally conducted with each other inside the profile cavity. Side plate connection holes are provided on both sides of the profile body between the symmetrical inner cavity rib plates. The wall thickness of the profile body around the outside of the profile cavity is the same. The overall strength of the side profile is strengthened through the profile cavity, and inner cavity rib plates are also provided inside the profile cavity to strengthen the profile cavity, so as to facilitate the overall strength optimization.

[0007] The shape of the bottom convex edge is a rectangular long strip-shaped through parallel edge. An arc transition edge is provided at the connection between the upper end of the bottom convex edge and the side surface of the profile body. A chassis installation groove is provided parallelly between the lower end surface of the bottom convex edge and the upper end of the combined chute. Bottom chassis assembly holes are equidistantly provided at the longitudinal midline of the surface of the chassis installation groove. A chassis that is convenient for plug-in installation can be set on one side of the profile body through the bottom convex edge, and various chassis with different shapes can also be installed in the form of a groove, such as a bottom plate, a strip rack, a perforated plate, etc., to realize different bridges with various functions.

[0008] The shape of the combined chute is a downward C-shaped card slot. The shape of the slot opening of the combined chute matches the convex edge hook on the top surface of the profile body. The hanging brackets can be conveniently stacked up and down through the combined chute to realize the combined installation of the cable tray, and assembly tools such as hanging brackets can also be installed.

[0009] The shape of the underframe assembly holes is a horizontally-arranged arc-shaped waist hole. The centers of the underframe assembly holes are horizontally aligned with each other. The diameter of the underframe assembly holes is the same as that of the locking bolts. Adjustable underframe assembly is achieved through the underframe assembly holes, and it can also adapt to various different forms of underframes for grouped installation.

[0010] The shape of the side plate connection holes is a vertically-arranged arc-shaped waist hole. The side plate connection holes are arranged in two rows of equidistant arrays on the end surfaces of the profile body. The side plate connection holes are arranged vertically on both sides with the horizontal midline of the profile body as the reference. The diameter of the side plate connection holes is the same as that of the locking bolts. Vertically adjustable installation and connection of the side plates are achieved through the vertical side plate connection holes, facilitating the docking installation of two profile bodies by connecting the side plates.

[0011] The connecting side plate is a bent plug-in side plate. The upper end of the connecting side plate is connected by clamping with the inner side of the convex edge hook plate through the bent edge. The lower end of the connecting side plate is wrapped around the outside of the bent locking bolt. Fixed screw holes are arranged in an equidistant array in the middle of the surface of the connecting side plate. The connecting side plate is connected to the profile body connected by the fixed screw holes and the locking bolts. Through the connecting side plate, not only can the profile bodies connected at both ends be connected and fixed by the locking bolts, but also the upper end of the connecting side plate is clamped and fixed while the lower end avoids the bolts, thus realizing the smooth installation and connection fixation of the connecting side plate.

[0012] Beneficial effects:

[0013] By improving the originally thin bridge side plates into side profile bars of high-strength tensile molding, and through the overall strength of the hollow profile, the overall high strength of the assembled bridge is achieved. Moreover, an underframe can be set at the bottom between the side plates, facilitating the overall assembly strength and convenient installation and connection.

[0014] The overall strength of the side profile bars is strengthened through the profile cavity, and internal cavity rib plates are also arranged inside the profile cavity to strengthen the profile cavity, thus facilitating the overall strength optimization.

[0015] An underframe that is convenient for plug-in installation is set on one side of the profile body through the bottom convex edge, and various forms of underframes, such as bottom plates, bar frames, hole plates, etc., can be installed in the groove shape to realize different bridges with various functions.

[0016] Through the combined chute, the hanging frames can be conveniently stacked and combined up and down to achieve the combined installation of the bridge, and assembly tools such as hanging frames can also be installed.

[0017] Adjustable underframe assembly is achieved through the underframe assembly holes, and it can also adapt to various different forms of underframes for grouped installation.

[0018] The vertical side plate connection holes enable the vertical adjustment of the installation and connection of the side plates, facilitating the docking and installation of two profile bodies by the connecting side plates.

[0019] The connecting side plates can not only connect and fix the profile bodies connected at both ends through locking bolts, but also the upper end of the connecting side plate is clamped and fixed while the lower end avoids the bolts, thus realizing the smooth installation and connection fixation of the connecting side plates.
