Description

Technical Field

[0001] This document belongs to the technical field of cable trench brackets, and specifically relates to a combined cable trench bracket structure. Background Art

[0002] High-voltage cable lines are mainly laid in underground cable trenches or cable tunnels. Cable brackets are a widely used structural form for cable lines laid in trenches. According to the "Code for Design of Electric Power Engineering Cables (GB_50217-2007)", when cables are laid openly, supports and fixings such as cable brackets and cable trays should be used along the whole length. However, as the cable operating environment becomes more and more complex, at present, more than 90% of the cable channels are shared for power transmission and distribution. The 10-110 kV cables are stacked and intertwined, which brings great potential hazards to the operation of the cable lines and also causes many difficulties in the installation of cable brackets.

[0003] Most of the existing cable brackets are fixed structures, that is, the height, length, and installation position of the cable brackets are fixed, and they only have the function of supporting cables, with low flexibility. Summary of the Utility Model

[0004] In order to solve the above problems, this document proposes a combined cable trench bracket structure. The cable trench bracket includes a main bracket, a sub-bracket, and an arc plate. Plug-in arms are symmetrically and horizontally arranged at both ends of the main bracket. Connecting wing plates are symmetrically arranged longitudinally along the center lines on the front and back sides of the main bracket. A fixed assembly hole runs through the center of the upper surface of the main bracket. Translation card seats are plug-in mounted on the outer sides of the plug-in arms at both ends. Clamping edges are provided on the front and back surfaces of the plug-in arms. A plug-in guide groove runs horizontally through the bottom of the translation card seat. The translation card seats are symmetrically plug-in mounted at both ends of the main bracket through the plug-in guide grooves. Pressing hooks are provided on the front and back sides of the inner ends of the translation card seats. A sub-bracket is vertically and perpendicularly arranged in the middle of the upper surface of the translation card seat. An arc plate is provided inside the sub-bracket. By connecting the main bracket and the sub-bracket through the translation card seat, and the translation card seat is plug-in connected to the main bracket through the plug-in arm, the translation card seat can be conveniently and quickly adjusted according to the diameter of the cables to be erected. Moreover, a number of cable trench brackets can be arranged side by side through the connecting wing plates. The translation card seat can also be used as a base and directly placed on the ground without being fixed, and the cable trench brackets play the role of cable brackets, thus realizing the free adjustment of the cable trench brackets.

[0005] The main bracket is in the shape of a convex mounting and fixing bracket. There is an assembly mounting boss in the middle of the main bracket. The two ends of the assembly mounting boss are connected to the insertion arms in a concave arc transition manner. On the front and back sides of the assembly mounting boss, there are integrally vertical connection wing plates. A fixing assembly hole runs through the center of the upper surface of the assembly mounting boss. Through the cross-shaped outward-expanding main bracket, not only can the connection and fixation of the translation card seat be achieved, but also other main brackets can be connected through connecting rods, greatly increasing the combination and adaptability of the combined cable trench bracket.

[0006] The insertion arms are in the shape of connecting arm plates with two parallel side plates. The parallel spacing between the insertion arms is greater than the parallel spacing between the insertion guide grooves at the bottom of the translation card seat. The width of the insertion arms is less than the width of the insertion guide grooves. On the outer surface of the insertion arms, there are several vertically parallel clamping ridges. The clamping ridges are in the shape of pointed long ridges. The clamping ridges are arranged in a vertically parallel and equally spaced array on the outer surface of the insertion arms. The spacing between the clamping ridges is greater than the thickness of the pressing catch. The protruding width of the clamping ridges is greater than the groove depth of the pressing catch. Through the cooperation of the insertion arms and the clamping ridges on their outer sides, the translation card seat can be conveniently adjusted and fixed, and the insertion arms can also play a role in connecting the translation card seat, thus achieving a highly stable adjustment strength.

[0007] The translation card seat is in the shape of a right trapezoidal bracket seat. On the bottom of the translation card seat, there are symmetrically arranged insertion guide grooves with the horizontal midline as the reference. There is a concave arc on the inner hypotenuse surface of the translation card seat. A secondary bracket is vertically provided at the upper end of the translation card seat. There are corner seats at the four corners of the bottom of the translation card seat. At the ends of the outer sides of the two sides of the insertion guide grooves, there are pressing catches. The pressing catches are made of an inwardly retractable elastic material. One end of the pressing catch is connected to the side end of the translation card seat, and the other end of the pressing catch is provided with a fixing hook facing inward. On the symmetric outer side of the fixing hook, there is a pressing plate, and the pressing plate is connected to an outwardly expanding inclined plate from bottom to top. Through the translation card seat, not only can the connection and adjustment between the secondary bracket and the main bracket be achieved, but also the direct installation without fixation can be realized through the corner seats at the bottom of the translation card seat, greatly simplifying the installation difficulty. The design of the pressing catch can not only fix and limit the translation card seat, but also be conveniently pressed and adjusted to achieve convenient installation and setting.

[0008] The sub-bracket is a rib-cast type bracket, and the outer contour of the sub-bracket is a long rectangular plate. Reinforcing ribs are provided on both side surfaces of the sub-bracket, and a number of arc plates are provided on the inner surface of the sub-bracket at equal vertical intervals. The shape of the arc plate is a single-sided curved supporting arc plate, and one end of the arc plate is vertically plugged and fixedly connected to the surface of the sub-bracket. The arc of the arc plate is facing the outside of the end of the sub-bracket. The high-strength sub-bracket is used to ensure the supporting strength of the arc plate, and the arc plate can also be adjusted in linkage through the sub-bracket, so as to achieve cable installation adaptation. The plug-in connection with the sub-bracket can freely and conveniently adjust the number of arc plates, and the pressurization can adjust the number.

[0009] Beneficial effects:

[0010] By connecting the main bracket and the auxiliary bracket through the translation bracket, and the translation bracket is plugged into the main bracket through the plug-in arm, the translation bracket can be conveniently and quickly adjusted according to the diameter of the cable to be erected, and several cable trench brackets can be arranged side by side by connecting the wing plates, and the translation bracket can also be used as a base and placed directly on the ground without being fixed. It plays the role of a cable bracket through several cable trench brackets, thereby realizing the free adjustment of the cable trench bracket.

[0011] Through the cross-shaped outward-expanding main bracket, not only can the connection and fixation of the translational holder be realized, but also other main brackets can be connected through connecting rods, which greatly increases the combination and adaptability of the combined cable trench bracket.

[0012] The translational card holder can be conveniently adjusted and fixed through the cooperation of the plug-in arm and the clamping edge on its outer side, and the plug-in arm can also play a role in connecting the translational card holder, thereby achieving efficient and stable adjustment strength.

[0013] The translational bracket can not only adjust the connection between the sub-bracket and the main bracket, but also realize direct installation without fixing through the corner bracket at the bottom of the translational bracket, which greatly simplifies the installation difficulty. The design of the push-on hook can not only fix and limit the translational bracket, but also facilitate press adjustment to achieve convenient installation and setting.

[0014] The supporting strength of the arc plate is ensured by the high-strength sub-bracket, and the arc plate can also be adjusted in linkage through the sub-bracket to achieve cable installation adaptation. The plug-in connection with the sub-bracket can freely and conveniently adjust the number of arc plates and the booster adjustable number. BRIEF DESCRIPTION OF THE DRAWINGS
