Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a height-adjustable cable trench metal bridge. Background Art

[0002] In the construction of power projects, cables need to be laid. The cable trench is a groove for laying cables. A bridge will be set up in the cable trench to facilitate the laying of cables.

[0003] According to a cable trench bridge structure recorded in the patent with announcement number CN111817246B, when it is necessary to install the cable, first lower the clamping seat to disengage the positioning protrusion from the positioning groove, then slide the positioning clamping plate to move the card connector out of the card slot to release the lock on the clamping seat, then open the clamping seat, and the original cable will be clamped by the positioning clamping plate and the positioning base plate without any deviation, then place the newly installed cable in the installation groove of the placement table and the vacant lower positioning groove of the positioning base plate, then close the clamping seat and connect the new positioning clamping plate to the positioning base plate to further restrict the cable, and at the same time, the card connector of the positioning clamping plate extends into the card slot to lock the clamping seat.

[0004] The cable installation needs to pass through the placement plate installed on the installation bracket in sequence. However, during the installation of the installation bracket, there will be errors in manual measurement, resulting in the installation height of the installation bracket not being on the same horizontal line. Since the installation brackets are not at the same level due to the error, the cables are not at the same level. When there is an error in the height of two adjacent installation brackets, the cable will be bent at a certain angle during installation, which will cause damage to the cable. When the cable is dragged for the next installation, the edge of the placement plate will rub against the cable, causing damage to the insulation layer on the outside of the cable, affecting its service life. Based on this, a height-adjustable cable trench metal bridge is now provided to eliminate the drawbacks of existing devices. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In one embodiment, Figure 1-Figure 6 As shown, a height-adjustable cable trench metal bridge comprises a bridge body 101 and mounting brackets 102 symmetrically arranged on the inner side of the side wall of the bridge body 101, the mounting bracket 102 is provided with a mounting frame 103 for the cable to pass through, and the mounting frame 103 is provided with a limiting plate 105 for limiting the entry of multiple cables.

[0029] The bridge body 101 is used to support the installation bracket 102, and the installation bracket 102 is used to support the installation frame 103. The cables pass through the limit plate 105 in sequence. The limit plate 105 limits the cables and is used to guide multiple cables to avoid the cables being arranged in a mess on the limit plate 105. This is not only unsightly, but also causes damage to the cables. Multiple cables are entangled together, which is not conducive to the installation and pulling of the cables by the staff.

[0030] In one embodiment, Figure 3-Figure 4As shown, the limiting plate 105 is provided with a guide group for the cables to pass through in sequence.

[0031] A guide group is provided on the limit plate 105, and this guide group is used to limit the cable. The cable passes through the guide group, which is conducive to the orderly installation of the cable on the limit plate 105. The staff needs to hold one end of the cable with one hand, align the cable with the guide group and pull it to drive the cable to pass through the guide group. There are multiple such guide groups, which can limit multiple cables so that multiple cables can be installed in an orderly manner on the limit plate 105, avoiding the situation where multiple cables are entangled with each other, which will cause the insulation layers of the cables to rub against each other, or the cables will be entangled and bent, causing irreversible damage to the insulation layers of the cables and affecting the service life of the cables; such a guide group can be a long strip block, which is arranged at the upper end of the limit plate 105, and the long strip block is provided with a threading groove for the cable to pass through along the direction in which the cable passes through. Such a guide group can also be a plurality of round blocks arranged along the direction in which the cable passes through, and the round blocks are provided with a threading groove for the cable to pass through.

[0032] In one embodiment, Figure 3-Figure 4 As shown, there are several guide groups, which include several guide frames 104 for the cables to pass through.

[0033] The guide frame 104 is arranged at the upper end of the limit plate 105 along the direction in which the cable passes. There are several guide frames 104, but at least two. The guide frames 104 are arranged along the direction in which the cable passes. The guide frames 104 are provided with gaps for the cable to pass through. The guide frames 104 are made of rubber material to prevent the material from being too hard to scratch the outside of the cable and cause damage to the cable.

[0034] In one embodiment, Figure 3-Figure 4 As shown, the limit plate 105 is provided with a buffer mechanism for reducing friction when pulling the cable.

[0035] The buffer mechanism is used to prevent the cable from being damaged due to friction with the edge of the limit plate 105. Before installing the cable, the mounting bracket 102 needs to be installed. The mounting bracket 102 is used to install the mounting frame 103, and the cable needs to pass through the mounting frame 103. However, during the installation of the mounting bracket 102, there may be errors in manual measurement, resulting in the installation height of the mounting bracket 102 not being on the same horizontal line, thereby causing the cables to be at different horizontal heights. When there is an error in the height of two adjacent mounting brackets 102, the cable will be bent at a certain angle during installation, which will cause damage to the cable. When the cable is dragged for the next installation, the edge of the limit plate 105 will rub against the cable, causing damage to the insulating layer on the outside of the cable, affecting its service life. In order to prevent the edge of the limit plate 105 from rubbing against the cable, a buffer mechanism is used to convert this friction into kinetic energy for pulling the cable forward.

[0036] In one embodiment, Figure 3-Figure 6 As shown, the buffer mechanism includes a first rolling group arranged at the inlet end of the limiting plate 105 and a second rolling group arranged at the outlet end of the limiting plate 105 .

[0037] The first rolling group and the second rolling group are respectively arranged at the inlet and outlet ends of the limit plate 105. When the staff installs the cable, they need to pull one end of the cable by hand to pass it through the guide group. Since the mounting bracket 102 is not at the same height, the mounting frame 103 will be at different heights, and the mounting frame 103 is not at the same height, the limit plate 105 will be at different heights. When the cable is installed on the limit plates 105 at different heights, it will bend. During the pulling process, the cable will contact the edge of the limit plate 105 and generate friction, which will cause wear on the insulating layer on the outside of the cable. When the wear is too great, it will cause damage to the inside of the cable, affecting its service life. By arranging the first rolling combination and the second rolling group at the inlet and outlet ends of the limit plate 105, the cable is prevented from contacting the edge of the limit plate 105, thereby avoiding the above situation and protecting the cable.

[0038] In one embodiment, Figure 3-Figure 6 As shown, the first rolling group includes a first roller 301 and a second roller 302, and the second rolling group includes a third roller 303 and a fourth roller 304; the first roller 301 is rotatably arranged above the guide frame 104 where the side of the inlet end of the limiting plate 105 is located; the second roller 302 is rotatably arranged below the guide frame 104 where the side of the inlet end of the limiting plate 105 is located; the third roller 303 is rotatably arranged above the guide frame 104 where the side of the outlet end of the limiting plate 105 is located; the fourth roller 304 is rotatably arranged below the guide frame 104 where the side of the outlet end of the limiting plate 105 is located.

[0039] The limiting plate 105 is slidably matched with the inner wall of the installing frame 103 on both sides near the installing frame 103, and the other two sides of the limiting plate 105 are provided with fixed plates, and the sides of the fixed plates are symmetrically provided with installing groups, and the installing groups include two installing plates, a first roller 301 is rotatably provided between the installing plates near the inlet end of the limiting plate 105, a second roller 302 is rotatably provided between the installing plates below the first roller 301 where the side of the limiting plate 105 is located, a third roller 303 is rotatably provided between the installing plates near the outlet end of the limiting plate 105, and a fourth roller 304 is rotatably provided between the installing plates below the third roller 303 where the side of the limiting plate 105 is located; the first roller 301, the second roller 302, the third roller 303 and the fourth roller 304 are used to prevent the cable from contacting the edge of the limiting plate 105 and causing damage to the cable.

[0040] In one embodiment, Figure 3-Figure 6As shown, the sides of the first roller 301, the second roller 302, the third roller 303 and the fourth roller 304 are respectively provided with a plurality of sliding grooves matched with the guide group.

[0041] The sliding groove is used to limit the position of the cable to prevent the cable from deviating from the first roller 301, the second roller 302, the third roller 303 and the fourth roller 304, thereby further enhancing the protection of the cable.

[0042] In one embodiment, Figure 3 and Figure 6 As shown, the installation frame 103 is provided with an adjustment mechanism for driving the limiting plate 105 to adjust the height.

[0043] The adjusting mechanism includes a screw rod 201, a guide rod 202 and a rotating block 203. One end of the screw rod 201 is connected to the rotating block 203, and the other end of the screw rod 201 passes through the bottom wall of the installation frame 103 and rotates with the limit plate 105. The bottom wall of the installation frame 103 is provided with a thread that cooperates with the screw rod 201. One end of the guide rod 202 passes through the bottom wall of the installation frame 103 and rotates with the limit plate 105. The rotating block 203 is rotated to drive the screw rod 201 to rotate. The screw rod 201 cooperates with the bottom wall of the installation frame 103 to drive the limit plate 105 to adjust the height. When the height difference between adjacent mounting brackets 102 is too large, the height of the limit plate 105 can be adjusted by rotating the rotating block 203 so that the cables are installed at the same height.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
