Description

Technical Field

[0001] This utility model relates to cable trench supports, and more particularly to a cable trench support and its prefabrication device. Background Technology

[0002] A cable trench is an underground conduit used for laying and replacing power or telecommunications cables, and it also serves as the enclosure structure for the cables being laid. Cable trench supports are frames installed within the cable trench to support the cables.

[0003] Cable trench supports consist of a main frame and multiple cross braces, one end of which is welded to the main frame. The cross braces are spaced apart along the extension direction of the main frame. Currently, the traditional manufacturing process for cable trench supports is: material preparation → dimensional measurement → positioning → fixing → welding → grinding → painting.

[0004] However, the above steps need to be repeated for each bracket, requiring a significant investment of manpower and resources during peak construction periods. Furthermore, the cutting and grinding operations can cause personal injury due to environmental factors, personnel, and different manufacturing methods. This not only affects the construction period but also leads to dimensional deviations and irregular shapes in the brackets due to personnel and environmental factors, potentially resulting in differences in the quality and appearance of each bracket and making it difficult to guarantee consistency and quality stability.

[0023] Reference will now be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided to explain the present invention and not to limit it. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the scope or spirit thereof. For example, features shown or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover these modifications and variations that fall within the scope of the appended claims and their equivalents.

[0024] As used herein, the terms “first,” “second,” and “third” are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of the individual components.

[0025] Figures 1 to 5 The prefabrication device for the cable trench support 1 of this utility model is shown, wherein, Figure 1 A schematic diagram illustrates the fabrication of a cable trench support 1 using the prefabrication device of this invention. The cable trench support 1 comprises a main frame 11 and multiple cross braces 12. One end of each cross brace 12 is welded to the main frame 11, and the cross braces 12 are spaced apart along the extension direction of the main frame 11. The spacing between adjacent cross braces 12 is equal, and the cross braces 12 are perpendicular to the main frame 11. The main frame 11 is made of 7.5# angle steel.

[0026] The prefabrication device of this utility model includes a base 100, a main frame positioning assembly, a cross brace positioning assembly 300, and a cross brace 12 balancing assembly 400. The main frame positioning assembly, the cross brace positioning assembly 300, and the cross brace 12 balancing assembly 400 are all fixed on the base 100. The base 100 can be selected as two 75# channel steels, which establish a stable construction platform for the cable trench support 1.

[0027] The main frame positioning assembly includes a first main frame positioning part 210 and a second main frame positioning part 220, the distance D between the two being the same as the width of the main frame 11, such as... Figure 4 As shown, this is for positioning the main frame 11. Combined with... Figure 1 and Figure 4 The main frame 11 can be directly placed between the first main frame positioning part 210 and the second main frame positioning part 220, and the positioning method is simple.

[0028] Considering that there are multiple cross braces 12 of the cable trench support 1, there are multiple cross brace positioning components 300 of this utility model. The multiple cross brace positioning components 300 are arranged at intervals, and each cross brace positioning component 300 corresponds to one cross brace 12 for positioning the cross brace 12.

[0029] like Figure 1 As shown, the balancing component 400 of the cross brace 12 is positioned away from the main frame positioning component relative to the cross brace positioning component 300. The height of the balancing component 400 of the cross brace 12 is the same as the height of the main frame 11, and the cross brace 12 can be placed on the balancing component 400 of the cross brace 12. The balancing component 400 of the cross brace 12 serves to balance the cross brace 12 and the main frame 11, making the cross brace 12 more stable.

[0030] The prefabrication device for the cable trench support 1 of this utility model positions the main frame 11 through the main frame positioning component and the cross brace 12 through the cross brace positioning component 300 and the cross brace 12 balancing component 400. This can better standardize the production of cable trench supports 1 that meet the drawing requirements, ensure the accuracy and quality of the support products, avoid product quality problems caused by different production environments, personnel, and production methods, significantly improve the quality, consistency, and quality stability of the supports, and effectively improve work efficiency and save costs.

[0031] This invention allows for modular prefabrication of the support frame, reducing the prefabrication steps to: material preparation → placement → welding → grinding → painting. The "placement" step involves first placing the main frame 11, followed by the placement of the multiple cross braces 12. By reducing the time spent on dimensional measurement, positioning, and fixing, significant manpower and material resources are reduced, greatly saving prefabrication time and improving the safety of the support frame, while also significantly enhancing its overall aesthetic quality.

[0032] Combination Figure 1 and Figure 4 The extension direction of the main frame 11 of the cable trench support 1 is defined as the first direction XX, and the direction on the plane where the base 100 is located and perpendicular to the first direction XX is defined as the second direction YY. The second direction YY is also the extension direction of the cross brace 12.

[0033] In one embodiment, the first main frame positioning portion 210 includes a plurality of first positioning channel steels 211, and the second main frame positioning portion 220 includes a plurality of second positioning channel steels 221. The plurality of first positioning channel steels are spaced apart along a first direction XX, and the plurality of second positioning channel steels 221 are spaced apart along the first direction XX, so that the main frame 11 is arranged along the first direction XX.

[0034] Furthermore, the waist of the first positioning channel steel 211 (i.e., the wide side of the channel steel) and the waist of the second positioning channel steel 221 are opposite each other, and the distance between them is consistent with the width of the main frame 11.

[0035] like Figures 1 to 5 As shown, the number of first positioning channel steels 211 can be six, and the number of second positioning channel steels 221 can be four, all of which are 10# channel steel. The first positioning channel steels 211 and the second positioning channel steels 221 are fixed on the surface of the platform according to the dimensions of the main frame 11 in the drawing, so as to fix and position the main frame 11.

[0036] In one embodiment, the prefabrication device of this utility model further includes a limiting channel steel 500 fixed on the base 100. The waist of the limiting channel steel 500 is perpendicular to the first direction XX and is used to abut against one end of the main frame 11 to limit the position of the main frame 11 in the first direction XX. The position of the limiting channel steel 500 needs to be determined according to the length of the main frame 11 and the position of the cross brace 12. The limiting channel steel 500 can be selected as a No. 10 channel steel.

[0037] like Figure 1 As shown, the main frame 11 can be positioned by placing one end of the first positioning channel steel 211 and the second main frame 11 against the wide surface of the limiting channel steel 500, which facilitates the subsequent assembly and positioning of the cross brace 12.

[0038] In one embodiment, the cross brace positioning assembly 300 extends along the second direction YY. The number of cross brace positioning assemblies 300 can be adjusted according to the maximum number of cross braces 12 of the cable trench bracket 1. The number of cross braces 12 is consistent with the number of cross brace positioning assemblies 300, but is not limited to such a number. Figures 1 to 5 The five shown.

[0039] The cross brace positioning assembly 300 includes a first cross brace positioning portion 310 and a second cross brace positioning portion 320. The first cross brace positioning portion 310 is used to position the cross brace 12 relative to the main frame 11. The second cross brace positioning portion 320 includes a plurality of main positioning angle steels arranged along a second direction YY to limit the included angle between the cross brace 12 and the main frame 11.

[0040] Specifically, the first cross brace positioning portion 310 includes end positioning angle steels 311. Multiple end positioning angle steels 311 are spaced apart along a first direction XX. The back of the end positioning angle steels 311 and the waist of the second positioning channel steel 221 are located on the same straight line.

[0041] The prefabrication device of this utility model uses the wide surface between the first positioning channel steel 211 and the second positioning channel steel 221 and the end positioning angle steel 311 to fix the main frame 11, which can effectively prevent the deformation of the main frame 11 during the welding process.

[0042] The end positioning angle steel 311 is disposed between two adjacent second positioning channel steels 221, and there is a gap between it and the adjacent second positioning channel steel 221. This gap facilitates the insertion of the support material and its removal after completion.

[0043] like Figure 1 , Figure 3 and Figure 4As shown, the second cross brace positioning part 320 includes a first main positioning angle steel 321, a second main positioning angle steel 322, and a third main positioning angle steel 323 arranged along the second direction YY. The first limb of the first main positioning angle steel 321, the second limb of the second main positioning angle steel 322, and the back of the end positioning angle steel 311 are located on the first straight line AA. The first limb of the third main positioning angle steel 323 is located on the second straight line BB, which is parallel to the first straight line AA. The distance between the first straight line AA and the second straight line BB is the same as the width of the cross brace 12. The combination of the first main positioning angle steel 321, the second main positioning angle steel 322, and the third main positioning angle steel 323 can fix and position the cross brace 12 and effectively control the deformation of the cross brace 12 caused during welding.

[0044] The end positioning angle steel 311, the first main positioning angle steel 321, the second main positioning angle steel 322, and the third main positioning angle steel 323 can be selected as No. 4 angle steel.

[0045] In one embodiment, the cross brace 12 balancing assembly 400 includes a balancing angle steel 410. There is at least one balancing angle steel 410, and its dimensions are the same as the main frame 11 of the cable trench support 1, for example, 7.5# angle steel. The balancing angle steel 410 extends along a first direction XX. The length of the balancing angle steel 410 is greater than or equal to the maximum distance between the two end positioning angle steels 311.

[0046] In one specific embodiment, the base 100 is 2350mm long and 720mm wide, and its main function is to ensure that the cross brace 12 and the main frame 11 (7.5# angle steel) are on the same horizontal plane.

[0047] The cable trench support 1 of this utility model can be manufactured by a prefabrication device of the cable trench support 1 as described in any of the above embodiments.

[0048] After the materials are cut, the main frame 11 and the cross brace 12 can be placed sequentially in the prefabrication device of this utility model. Through the corresponding gaps set in the device, the main frame 11 and the cross brace 12 can be precisely fixed and positioned directly, achieving the functions of rapid positioning and accurate welding. No separate measurement or manual fixing is required, thereby greatly improving the quality, consistency and quality stability of the support.

[0049] This invention can effectively improve work efficiency and save costs; due to the reduction of human factors and the fixed environment for the support fabrication, the safety of operators is greatly improved.

[0050] This invention utilizes a combination design of multiple sets of angle steel and channel steel to effectively fix and position materials, preventing deformation during welding and improving welding quality and efficiency. The base 100 design ensures that materials are placed on the same horizontal plane, providing a more stable working environment and making operation more convenient and efficient.

[0051] The gap design between the second positioning channel steel 221 and the end positioning angle steel 311 facilitates the insertion and removal of the main frame 11, improving operational convenience.

[0052] This invention improves assembly speed, reduces the risk of deformation, protects the integrity of welding materials, and enhances work efficiency and quality.

[0053] At the same time, this utility model is simple to operate, making it easier for construction workers to comply with safe operating procedures, ensuring the safety of operators and preventing accidents.

[0054] The prefabrication device for cable trench supports of this utility model is mainly composed of angle steel and channel steel commonly used on construction sites. The spacing between supports can be adjusted according to usage requirements so that it can meet the prefabrication of all cable trench supports 1 required.

[0055] Based on practical experience, over 1400 cable trench supports 1 were prefabricated on-site using the prefabrication device of this invention. This batch prefabrication significantly improved the efficiency of support installation. The prefabrication process reduced manpower and material resources considerably, saving approximately 50% of the time compared to individual prefabrication and installation.

[0056] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible variations and modifications without departing from the spirit and scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
