Description

Technical Field

[0001] The utility model relates to the technical field of cable supports, in particular to an aluminum alloy profile structure for a tunnel cable support. Background Art

[0002] In today's society, whether it is communication or electricity, the load is getting bigger and bigger, so the use of cables with various types of conductors is increasing. Because cables are mainly responsible for power or signal transmission, many cables pass through tunnels, so corresponding brackets need to be arranged in the tunnels to support the cables. Of course, there are many existing technologies.

[0003] For example, Chinese patent application number 201720906371.5 discloses a circular tunnel cable fixing bracket for power transmission and transformation projects, including an arc-shaped bracket and a communication cable box. A bracket is provided at one end of the arc-shaped bracket, and the bracket is fixedly connected to the arc-shaped bracket. Connecting plates are provided at both ends of the bracket, and the connecting plates are fixedly connected to the bracket.

[0004] For example, the Chinese patent application number 202120344161.8 discloses an adjustable circular tunnel cable support made of aluminum alloy profile, including: a first curved column, a first tensioning mechanism, a horizontal support arm, a horizontal cable clamp, a first connecting plate, a second curved column, a third curved column, a second tensioning mechanism, and a second connecting plate; the first curved column is arranged at the bottom end and is fixedly connected to the second curved column through the first tensioning mechanism and the second tensioning mechanism; the third curved column is arranged at the top end and is fixedly connected to the second curved column through the first connecting plate and the second connecting plate; the horizontal support arm is fixedly connected to the inner wall of the second curved column; the horizontal cable clamp is fixedly arranged on the top of the horizontal support arm.

[0005] Although the profile structure used in these existing brackets can achieve good cable installation effects, as the use of cables continues to increase, the number and weight of cables that the brackets need to bear will increase. The brackets will easily deform and need to be replaced as a whole. The maintenance space is relatively small, which is not very convenient. Utility Model Content

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0026] Examples, such as Figure 1-4As shown, the tunnel cable support uses an aluminum alloy profile structure, including a first profile frame and a second profile frame spaced apart in the front and rear directions. A plurality of axial profile reinforcement beams z are connected between the first profile frame and the second profile frame. The axial profile reinforcement beams z are used as reinforcement ribs extending in the front and rear directions. A cable mounting seat is installed and connected to the axial profile reinforcement beams z. The cable mounting seat is used for laying cables. The first profile frame, the second profile frame, the axial profile reinforcement beams z and the cable mounting seat are all aluminum alloy workpieces. Such a new design structure has better three-dimensionality and a more solid and stable structure. The first profile frame and the second profile frame are not easily deformed as a whole under a large load. The cable mounting seat installed in the axial profile reinforcement beams z extending in the front and rear directions has more space. The front and rear positions of the cable mounting seats on the axial profile reinforcement beams z at different positions can be different, which is convenient for subsequent replacement and maintenance. The specific implementation plan is as follows:

[0027] The first profile frame includes a first left curved beam 21 and a first right curved beam 22 that can be spliced ​​together. The first left curved beam 21 has an I-shaped cross section and forms a first left curved groove 210 on both the front and rear sides. The first right curved beam 22 has an I-shaped cross section and forms a first right curved groove 220 on both the front and rear sides. The first left curved beam 21 is generally C-shaped with its opening facing right. The first right curved beam 22 is arranged in a mirror-symmetrical manner with the first left curved beam 21. The cross section of the first left curved beam 21 is also a cross section perpendicular to the circumferential direction. The first left curved beam 21 and the first right curved beam 22 are spliced ​​at the top and bottom, respectively, to form a complete closed-loop structure, which is the front basic frame. Correspondingly, the second profile frame includes a second left arc-shaped beam 31 and a second right arc-shaped beam 32 that can be spliced ​​together on the left and right sides. The cross-section of the second left arc-shaped beam 31 is I-shaped and forms a second left arc-shaped groove 310 on the front and rear sides. The cross-section of the second right arc-shaped beam 32 is I-shaped and forms a second right arc-shaped groove 320 on the front and rear sides. The first profile frame and the second profile frame respectively form the most basic outlines of the cable support in the front and rear sides. Of course, the axial profile reinforcement beam z needs to be connected in the middle to form a complete support structure. The structure of the arc groove is formed naturally on the front and rear sides after the I-shaped cross-section is stretched into a solid arc-shaped beam. Furthermore, the axial profile reinforcement beam z is installed and connected between the adjacent first left arc-shaped groove 210 and the second left arc-shaped groove 310, as well as between the adjacent first right arc-shaped groove 220 and the second right arc-shaped groove 320. The specific installation and connection relationship is designed as follows:

[0028] The axial profile reinforcement beam z is integrally connected between the first left arc groove 210 and the second left arc groove 310 or integrally connected between the first right arc groove 220 and the second right arc groove 320. The axial profile reinforcement beam z includes a front end beam z1, an intermediate reinforcement beam z2 and a rear end beam z3 that are integrally connected front and rear. The cross-sections of the front end beam z1 and the rear end beam z3 are both fan-shaped. The fan-shaped shape is mainly to match the arc groove and to match the size as much as possible. Then, the front part of the front end beam z1 is embedded and integrally connected in the first left arc groove 210, or embedded and integrally connected in the first right arc groove 220, while the rear end beam z3 is integrally connected to the second left arc groove 310 or the second right arc groove 320. The intermediate reinforcing beam z2 is in the shape of a flat plate, and the intermediate reinforcing beam z2 can be in the shape of a rectangle. Furthermore, the intermediate reinforcing beam z2 is provided with an adjustment mounting hole z20 for installation and fixation with the cable mounting seat, and the cable mounting seat is also provided with a corresponding mounting hole for matching installation with the adjustment mounting hole z20. Then, the bolt passes through the mounting hole and the adjustment mounting hole z20 on the cable mounting seat to complete the installation and fixation of the cable mounting seat, and the number of the adjustment mounting holes z20 is set as much as possible, so that the assembly position of the cable mounting seat has many adjustment options for installation.

[0029] This is one implementation method. Another method is described below. Specifically, the axial profile reinforcement beam body z is detachably connected between the first left arc groove 210 and the second left arc groove 310, or is integrally connected between the first right arc groove 220 and the second right arc groove 320. This is a detachable connection method of the axial profile reinforcement beam body z. Unlike the above method, the axial profile reinforcement beam body z here is detachable, which makes replacement and maintenance more convenient. More specifically:

[0030] The first left arc-shaped beam body 21 is located in the first left arc groove 210 and is integrally connected with a plurality of first left reinforcing ribs 2100 extending radially and arranged at intervals in the circumferential direction. There are at least two first left reinforcing ribs 2100, preferably 6 or more, and two circumferentially adjacent first left reinforcing ribs 2100 are separated in the first left arc groove 210 to form a fan-shaped first left plug-in mounting hole 21000. The second left arc-shaped beam body 31 is located in the second left arc groove 310 and is integrally connected with a plurality of first left reinforcing ribs 2100 extending radially and arranged at intervals in the circumferential direction. The second left reinforcing ribs 3100 are arranged at intervals, and two circumferentially adjacent second left reinforcing ribs 3100 are separated in the second left arc groove 310 to form a fan-shaped second left plug-in mounting hole 31000. The first right arc-shaped beam 22 is located in the first right arc groove 220 and is integrally connected to a plurality of radially extending and circumferentially spaced first right reinforcing ribs 2200. The two circumferentially adjacent first right reinforcing ribs 2200 are separated in the first right arc groove 220 to form a fan-shaped first right plug-in mounting hole 22000.

[0031] Correspondingly, the second right arc-shaped beam 32 is located in the second right arc-shaped groove 320 and is integrally connected with a plurality of second right reinforcing ribs 3200 extending radially and arranged at intervals in the circumferential direction. Two circumferentially adjacent second right reinforcing ribs 3200 are separated in the second right arc-shaped groove 320 to form a fan-shaped second right plug-in mounting hole 32000.

[0032] The axial profile reinforcement beam body z can still include a front end beam body z1, an intermediate reinforcement beam body z2 and a rear end beam body z3 that are integrally connected front and back, and the cross-sections of the front end beam body z1 and the rear end beam body z3 are both fan-shaped, and the intermediate reinforcement beam body z2 is flat. However, the front end beam body z1 and the rear end beam body z3 on the same axial profile reinforcement beam body z are respectively plugged into the first left plug-in mounting hole 21000 and the second left plug-in mounting hole 31000 or respectively plugged into the first right plug-in mounting hole 22000 and the second right plug-in mounting hole 32000. It can be seen that the structure of the axial profile reinforcement beam body z can refer to the previous implementation method, but it is not an integrally connected structure, and can be plugged in and installed in a front-to-back plug-in manner. Moreover, only the front and rear plug-in can be used. If the fixed strength is required, a hole structure perpendicular to the axial direction can be opened on the adjacent reinforcing ribs and the corresponding inserted end beams, and the axial limit locking can be completed by passing a pin s through the three. The circumferential hole limit itself does not require other limits. For example, in the first left plug-in mounting hole 21000, the two adjacent first left reinforcing ribs 2100 and the front end beam z1 inserted into the hole are respectively provided with corresponding holes perpendicular to the axial direction. After plugging in, a pin is inserted into the corresponding holes of the three continuously from one side, and a nut fixing structure can be installed on the other side to limit the two sides, thereby realizing the axial position locking of the three.

[0033] Preferably, the intermediate reinforcing beam z2 is provided with an adjustment mounting hole z20 for mounting and fixing with a cable mounting seat, and the cable mounting seat comprises a base plate 11 mounted and connected to the intermediate reinforcing beam z2, a fixed support plate 12 integrally connected to the front of the base plate 11, an adjustment support leg 13 that can be retracted and connected to the base plate 11, a cable mounting plate 14 connected between the top of the adjustment support leg 13 and the top of the fixed support plate 12, a cable placement frame 140 integrally connected to the side of the cable mounting plate 14 facing away from the base plate 11, and the top of the adjustment support leg 13 is connected to the cable. The back of the cable installation plate 14 is hingedly connected, the bottom end of the adjusting support leg 13 is hingedly connected to the front of the base plate 11, and the top of the fixed support plate 12 is hingedly connected to the back of the cable installation plate 14. The front of the base plate 11 is the surface part on the side facing away from the middle reinforcing beam z2. The adjusting support leg 13 and the fixed support plate 12 are both on the front side of the base plate 11. The end of the adjusting support leg 13 and the fixed support plate 12 connected to the base plate 11 is the bottom end and the end connected to the cable installation plate 14 is the top end. The side of the cable installation plate 14 facing away from the base plate 11 is the front and is used to set the cable insertion frame 140.

[0034] Corresponding mounting holes are provided on the base plate 11 to mate with the adjustable mounting holes z20. As mentioned above, this allows the base plate 11 to be removably fixedly connected to the intermediate reinforcement beam z2 by means of bolts m. The fixed support plate 12 can be a single upright plate. The hinged connection can be achieved by forming a hinge axis on the back of the cable mounting plate 14 and forming a sleeve corresponding to the hinge axis on the top of the adjustable support leg 13. In this way, the cable mounting plate 14 is movable relative to the adjustable support leg 13. The hinged structure at the other two locations can also adopt this method. The main purpose is to ensure that the connection at these three locations is not locked, but provides support and mobility. By adjusting the length of the support leg 13, the angle of the cable mounting plate 14 can be fine-tuned, allowing the cable mounting plate 14 to be adjusted to a more precise position. The adjustable support leg 13 can adopt a conventional aluminum alloy cylinder structure or a conventional aluminum alloy length-adjustable screw-type adjustment structure. The upper and lower ends of the adjustable support leg 13 are respectively hingedly connected to the cable mounting plate 14 and the base plate 11. The cable placement frame 140 may adopt an existing frame type, such as a plurality of consecutive locking hoops on the left and right or a plurality of locking hoops arranged in a pyramid shape, and the locking hoops may be opened and closed to lock.

[0035] Preferably, the upper end portion and the lower end portion of the first left arc-shaped beam body 21 are respectively connected as a whole with the upper left reinforcing end plate 41 and the lower left reinforcing end plate 42, and the upper end portion and the lower end portion of the first right arc-shaped beam body 22 are respectively connected as a whole with the upper right reinforcing end plate 51 and the lower right reinforcing end plate 52, and the upper left reinforcing end plate 41 and the upper right reinforcing end plate 51 are connected with an upper tensioning assembly, and the above-mentioned reinforcing end plates can be rectangular plates, and the upper tensioning assembly can also adopt an existing tensioning structure, for example, the upper tensioning assembly is a latch-type connector or an articulated connector, specifically including a left screw hingedly connected to the upper left reinforcing end plate 41. The screw sleeve 61 and the right screw sleeve 62, which is hingedly connected to the upper right reinforcing end plate 51, also include an operating lever that can be screwed into both the left and right screw sleeves 61 and 62. The operating lever includes a left-hand screw 63, an intermediate operating lever 64, and a right-hand screw 65, which are integrally connected left and right. The intermediate operating lever 64 can be hexagonal or simply a nut. Using a specialized tool such as pliers, the left-hand screw 63 and the right-hand screw 65 can be screwed into the left and right screw sleeves 61 and 62, respectively, thereby achieving tension between the first left and right curved beams 21 and 22, and ensuring tension between the entire closed loop and the tunnel after splicing. A lower tensioning assembly is connected between the corresponding left and right reinforcing end plates 42 and 52, adopting the same structural design as the upper tensioning assembly. Similarly, the second left and right curved beams 31 and 32 are also integrally connected to the corresponding upper and lower reinforcing end plates, and the reinforcing end plates are connected via a tensioning assembly.

[0036] Of course, when the above-mentioned aluminum alloy profile structure is in use, it needs to be further positioned after installation. For example, the first left curved beam 21 of the first profile frame is further limited by setting limit piles or anchors on the front and rear sides of the first left curved beam 21 in the tunnel.

[0037] The installation of the entire aluminum alloy profile structure is relatively simple. For example, the first profile frame and the second profile frame are first placed in the tunnel, and the axial profile reinforcement beam z is placed between the first profile frame and the second profile frame. The first profile frame and the second profile frame are tensioned and tensioned in the tunnel through the tensioning assembly. Then, the first profile frame and the second profile frame themselves can be limited and locked in the front and back of the tunnel. Then, the cable mounting seat can be installed and the cables can be assembled.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
