After the cables are installed, they are not only beautiful, but also have sufficient isolation space and clear layers between the cables, so that maintenance personnel can quickly distinguish the cables and find maintenance points. Compared with a wall-mounted bracket, the operating equipment is easy to operate, which improves the installation efficiency and quality. Moreover, the isolation fixture of the present invention can offset most of the load by means of the supporting force of the side wall of the cable trough, which greatly improves the stability and reliability of the isolation fixture.

Description

Technical Field

[0001] The invention relates to the technical field of railway electrical appliance accessories, and in particular to a bent-angle fixed cable isolation bracket which does not occupy the bottom space of a railway cable trough. Background Art

[0002] During railway construction, especially the construction of railway four-electric (communication, signal, power and traction substation) projects, a large number of cables need to be laid to ensure the safe operation of trains. However, due to the limitations of various factors such as construction costs and current railway industry standards, the width of railway section cable troughs is usually 200-300mm and the depth is usually 300mm. After deducting the space occupied by railway line equipment and cable connectors in the cable trough, the space available in the cable trough for cable laying and isolation between cables is very limited. Therefore, in order to facilitate construction and control construction costs, in actual construction, construction units usually place cables of various specifications directly in the cable trough. Not only do the cables lack obvious signs, but the cables are also placed in a disorderly manner. In order to ensure the normal operation of the railway, the line maintenance unit can only use the short maintenance time during the avoidance of driving or in the early morning to inspect and repair the cables. The above cable laying method greatly reduces the efficiency of cable maintenance and inspection.

[0003] At the same time, due to the excessive number of lines stacked in the cable trough, the cables will completely block the bottom of the cable trough, resulting in the inability to remove various foreign objects such as sewage, garbage and mud that enter the cable trough in time, affecting the rapid search of the cables and causing great difficulties for the subsequent cable maintenance. At the same time, the above-mentioned dirt has a certain damage to the protective layer on the surface of the cable, shortening the service life of the cable; in order to solve the above problems in the prior art, a floor-standing wiring bracket or a wall-mounted wiring bracket is often set up in the cable trough. Although the floor-standing wiring bracket can ensure the orderly laying and installation of the cables, it will occupy the space at the bottom of the cable trough. At the same time, in order to ensure the mechanical strength of the wiring bracket, the wiring bracket needs to be thickened, thereby occupying more space, further reducing the space available for cable laying in the cable trough; and in the prior art, the cables are generally transported in a coiled manner, and the structural strength of the cables themselves is relatively large. It is extremely difficult to completely straighten the cables during the laying process. The cables installed in the above manner are still crooked after laying.

[0004] If a wall-mounted wiring bracket is used for wiring operations, although it does not need to occupy the lower space of the cable trough and the wiring effect is better, its anchoring equipment needs to be driven into the side wall of the cable trough, and the spacing between the two side walls of the cable trough is small, the space available for construction operations is limited, and construction tools such as electric hammers and electric drills cannot work normally. Even if the forced installation is successful, the connection strength between the wall-mounted wiring bracket and the side wall of the cable trough is limited. After long-term use, not only is the bracket prone to loosening, but the anchoring equipment will also cause irreversible damage to the low-strength concrete side wall of the cable trough. Not only can it not meet the quality requirements of the century-old railway project, but it also makes the later maintenance difficult and the maintenance cost high. Therefore, in the existing railway construction, there is an urgent need for a wiring equipment that has the advantages of both a floor-standing wiring bracket and a wall-mounted wiring bracket. Summary of the invention

[0005] In view of the defects in the prior art such as the difficulty in installing and loose installation of wiring brackets in small-sized cable troughs, the large space occupied by the clamps resulting in cable chaos and difficulty in discharging debris, the present invention discloses an angled fixed cable isolation bracket which does not occupy the bottom space of the railway cable trough. The present invention is not only small in size and easy to install, but also has a high connection strength between the clamp and the cable trough, effectively ensuring the construction quality of railway cable laying. The cables are clearly layered after laying, which is convenient for subsequent maintenance and inspection.

[0006] The present invention achieves the above object through the following technical solutions:

[0007] A bent angle fixed cable isolation bracket which does not occupy the bottom space of a railway cable trough comprises a cable hook and a hook connecting piece which are fixedly connected. A fixing piece which fits the top surface of the cable trough is folded on the hook connecting piece, and a fastening device which fixes the fixing piece to the cable trough is provided on the fixing piece.

[0008] Preferably, a second hook connecting piece is further provided at the free end of the fixing piece, the second hook connecting piece is parallel to the hook connecting piece, and the free ends of the second hook connecting piece and the hook connecting piece are oriented in the same direction.

[0009] Preferably, the hook connecting piece is L-shaped, and one end of the hook connecting piece is folded outwardly to be provided with a fixing piece.

[0010] Preferably, the hook connecting piece is U-shaped, and both ends of the hook connecting piece are respectively provided with outwardly folded fixing pieces.

[0011] Preferably, the cable hook is provided with a connecting hole adapted to the hook connecting piece, mutually cooperating elastic lock buckles and retreat grooves are provided between the connecting hole and the cable hook, and the hook connecting piece is provided with a locking groove that is compatible with the elastic lock buckle.

[0012] Preferably, a first clamp and a first slot that cooperate with each other are arranged between the cable hook and the hook connecting piece; an elastic lock buckle and a lock slot that cooperate with each other are also arranged between the cable hook and the hook connecting piece; a lower limit block and a limit slot that cooperate with each other are also arranged between the cable hook and the hook connecting piece.

[0013] Preferably, the lower limit block includes a first lower limit block, and the hook connecting plate is provided with a limit groove adapted to the first lower limit block; a limit card is fixedly provided on the first lower limit block, the limit card abuts against the fixed plate, and the limit card is T-shaped, I-shaped, regular polygonal, circular or elliptical.

[0014] Preferably, the lower limit block further includes a second lower limit block, the second lower limit block is integrally connected with the first clamp, and the first slot and the second lower limit block abut against each other.

[0015] Preferably, a second clamp and a second slot that match each other are provided between the two sides of the top of the cable hook and the hook connecting piece.

[0016] Preferably, the hook connecting piece is connected to the fixing piece via a hinge, and 1 to 4 cable hooks are evenly arranged on the hook connecting piece.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention comprises a cable hook and a hook connecting piece. One end of the hook connecting piece is folded to be provided with a fixing piece that fits with the top surface of the cable trough. The hook connecting piece and the fixing piece form an L shape. During installation, the fixing piece fits with the top surface of the cable trough, and the back of the cable hook on the hook connecting piece fits with the inner wall of the cable trough. After installation, the entire isolation fixture is completely fitted with the cable trough. Compared with the traditional floor-standing cable bracket, the isolation fixture and the cable described in the present invention are both mounted on the upper part of the cable trough, and the lower part of the cable trough is in an empty state. Therefore, the cable line will not block the discharge of sewage, mud and other debris in the cable trough, which is beneficial to the daily maintenance of the cable trough. At the same time, the overall structure of the present invention is an L-shaped structure, and an installation method of fixing the bent angle is adopted. The product structure is greatly simplified. At the same time, some components are located outside the cable trough, so the space occupied by the components located in the cable trough is effectively reduced, which can greatly improve the wiring capacity of the cable trough, and in the section with fewer cables, the size of the cable trough can be reduced to reduce the construction cost.

[0019] At the same time, compared with the inner wall fastening installation method of the traditional wall-mounted bracket, the isolation clamp of the present invention is directly hung and installed on the top of the cable trough, and the fastening connection is achieved by directly driving the fastening device located on the fixing plate into the top of the cable trough concrete, rather than driving the fastening device into the side wall of the cable trough for fixed installation. Therefore, the operating tool can complete the installation of the entire device outside the cable trough, and there is no need to place the operating tool in the cable trough to complete the fastening installation of the bracket. The construction is more convenient and quick, which greatly improves the adaptability of the bracket to small-sized cable troughs. Moreover, since the operating tool is more convenient to operate, it is easier for workers to control the installation quality, thereby improving the installation quality of the bracket.

[0020] The present invention adopts the isolation fixture of the above-mentioned bent angle structure. After the cable is laid, the fixture of the present invention can balance part of the shear force on the fixture connection parts by means of the support effect of the inner wall of the cable trough. Compared with the existing wall-mounted bracket, the force on the anchoring device is significantly reduced, thereby improving the stability and reliability of the equipment; at the same time, under the condition of certain force, the size of the fixing plate can be further reduced to meet the operation requirements of various narrow spaces. In the installation occasions where the size of the fixture does not need to be reduced, the fixture can mount more cables with heavier weight, and the fixture has a wider range of application;

[0021] The present invention can also distribute cables of various specifications in the cable trough in an orderly manner, realize the arrangement of cables of various specifications, improve the aesthetics of the cables after installation, and not only are there sufficient isolation spaces between the cables, but also the layers are clear, which is convenient for maintenance personnel to quickly distinguish the cables and find maintenance points in a shorter maintenance time, thereby improving the quality and efficiency of line maintenance.

[0022] 2. The free end of the fixing plate of the present invention is further provided with a second hook connecting plate parallel to the hook connecting plate, and the free ends of the second hook connecting plate and the hook connecting plate are oriented in the same direction. The fixing plate, the hook connecting plate and the second hook connecting plate together form a U-shape. During installation, the fixing plate is attached to the top surface of the cable trough, and the two hook connecting plates are respectively attached to the side walls of two parallel cable troughs. The above structure can better adapt to the installation conditions of two or more parallel cable troughs. Compared with the unilateral installation method, it not only saves materials, but also the forces of the cables on both sides offset each other, the fixing plate is hardly subjected to any force, and its stability is higher.

[0023] 3. The hook connecting piece of the present invention is L-shaped, and the hook connecting piece and the fixing piece are connected to form a Z shape. The suspended end of the hook connecting piece is used to mount cables with lower weight, and the side that is in contact with the inner wall of the cable trough is used to mount cables with heavier weight. It not only realizes the utilization of the side wall space of the cable trough, but also effectively utilizes the middle space of the cable trough. Each cable is reasonably distributed according to the carrying capacity of the hook connecting piece, and its wiring efficiency is higher and more reasonable.

[0024] 4. The hook connecting piece of the present invention is U-shaped, and its two ends are folded outward to provide fixing pieces. The horizontal plate of the hook connecting piece is used to mount cables with lighter weight, and the vertical plates on both sides are used to mount cables with heavier weight. The two fixing plates on both sides are used to fasten the connection, thereby improving the overall stability and reliability of the equipment. The two ends of the horizontal plate are respectively connected to the two vertical plates, thereby improving the supporting force of the horizontal plate, and the cable mounting capacity of the horizontal plate is stronger and has a wider range of use.

[0025] 5. The cable hook of the present invention is provided with a connecting hole adapted to the hook connecting piece, and elastic lock buckles and retreat grooves that cooperate with each other are provided between the connecting hole and the cable hook. The hook connecting piece is provided with a locking groove adapted to the elastic lock buckle. When in use, the hook connecting piece is directly inserted into the connecting hole, and the fastening connection between the hook connecting piece and the cable hook is achieved through the cooperation of the elastic lock buckle and the locking groove. The installation method is simple and quick, which improves the installation efficiency of the cable hook.

[0026] 6. The present invention also includes a cable hook, wherein a first clamp and a first slot that cooperate with each other are arranged between the two sides of the cable hook and the fixing plate, and an elastic lock buckle and a lock slot for preventing the cable hook from being strung up, and a lower limit block and a limit slot for preventing the cable hook from sliding down are also arranged between the cable hook and the fixing plate. Compared with the prior art, the cable hook is limited in both the horizontal transverse and horizontal longitudinal directions by the first clamp and the cable hook body, and a vertical downward constraint force is provided by the cooperation of the elastic lock buckle and the lock slot to prevent the cable hook from being strung up in the vertical direction during vibration, and a vertical upward constraint is provided by the lower limit block and the limit slot. The present invention simultaneously constrains the cable hook with 6 degrees of freedom in the horizontal transverse, horizontal longitudinal and vertical directions, thereby greatly improving the stability of the cable hook, preventing the cable hook from being separated from the fixing plate during long-term vibration, and improving the stability and reliability of the equipment.

[0027] At the same time, the present invention is provided with a first clamp and a first slot on the fixing plate, which can realize the connection between the fixing plate and the cable hook by sliding, which is not only convenient to install, but also compared with the traditional extruded cable installation method, the first clamp of the present invention does not need to have a certain elastic retreat space, so the structural strength of each connecting part is greater, which greatly improves the restraining force of the first clamp, and further improves the stability and reliability of the product described in the present invention.

[0028] 7. The lower limit block of the present invention comprises a first lower limit block and a second lower limit block. By setting a plurality of lower limit blocks, a greater supporting force can be provided for the cable hook, ensuring sufficient structural strength in the direction of the greatest force, avoiding the cable hook from being crushed by the cable, and improving the reliability of the equipment; at the same time, the second lower limit block and the first clamp are an integrated structure, and the bottom surface of the second lower limit block and the bottom surface of the first slot serve as lower thrust surfaces for each other. The above structure cleverly utilizes the existing structure of the cable hook and the fixing plate, and increases the connection force between the cable hook and the fixing plate as much as possible while ensuring that the product structure is minimally modified, thereby improving the stability and reliability of the equipment.

[0029] 8. The present invention has a limit card integrally connected to the first lower limit block. The limit card can be in any one of a T-shape, an I-shape, a circle, a regular polygon or an ellipse, and the side of the limit card is located outside the side of the first lower limit block to ensure that the bottom surface of the limit card contacts the top surface of the fixing plate, providing a restraining force for the cable hook in the longitudinal direction of the horizontal plane. The cooperation with the first clamp further increases the restraining force on the cable hook in the longitudinal direction of the horizontal plane, thereby improving the stability and reliability of the product.

[0030] 9. The present invention also provides a second clamp and a second slot that cooperate with each other on the top of the cable hook and the fixing plate. The second clamp and the second slot provide constraints in the horizontal longitudinal direction on the upper part of the cable hook with a separation tendency, thereby ensuring that the cable hook and the fixing plate are tightly fitted together, further improving the stability and reliability of the cable hook.

[0031] 10. The present invention is provided with 1-4 cable hooks on the hook connecting plate, which can not only meet the mounting requirements of multiple cables, but also can add cable hooks of different specifications to meet the mounting and wiring requirements of cables of different specifications, thereby improving the practicality of the product; at the same time, the hook connecting plate and the fixing plate are connected by a hinge mechanism, so that the hook connecting plate and the fixing plate can be installed at any angle, which greatly improves the adaptability of the device to the inner wall of the special-shaped cable trough and expands the scope of use of the device.

The specific structure is as follows: Fig.12 As shown, it comprises a hook connecting piece 2 and a cable hook 1 which are fixedly connected, the hook connecting piece 2 is U-shaped, and fixing pieces 3 are folded outwardly at both ends of the hook connecting piece 2, and the cable hook 1 is evenly fixedly connected on the horizontal and vertical surfaces of the U-shaped hook connecting piece 2, wherein a simple hook is fixedly provided on the horizontal section for mounting light cables, and the vertical surface is used for mounting heavy cables;

[0072] Further, such as Fig.13 As shown, the horizontal section flat plate of the hook connecting piece 2 can also be integrally formed with a plurality of grooves 21 for placing cables (that is, the horizontal section can be W-shaped or S-shaped), and the cables can be fixed to the hook connecting piece by bundling methods such as cable ties, so as to mount lighter cables; and the two vertical edges are used for mounting heavier cables; at the same time, the angle between the fixing piece 3 and the hook connecting piece 2 can be a right angle or any other angle to ensure that the shape of the fixture is compatible with the shape of the concrete blocks on both sides of the cable trough.

[0073] In the above embodiment, the hook connecting plate 2 and the fixing plate 3 can adopt an integrally formed structure, and can also be connected by welding. At the same time, in order to improve the adaptability of the product to cable troughs of different structures, the hook connecting plate 2 and the fixing plate 3 can also be connected by a hinge structure, thereby improving the adaptability of the device to the side wall of the cable trough.

[0074] It should also be pointed out that other free combinations of the technical solutions described in the above embodiments by those skilled in the art all fall within the protection scope of this application.

[0075] When the present invention is used, firstly, the first holding card is inserted into the first slot, the second holding card is inserted into the second slot, the first lower limit block is inserted into the limit slot, and the locking block of the elastic lock buckle is in close contact with the hook connecting piece, the elastic connecting piece is squeezed and deviated outward, at this time, the cable hook is slid downward, and the side of the hook connecting piece slides into the first holding card and the second holding card, when the elastic buckle slides to the locking slot, the elastic connecting piece automatically resets, the locking block is inserted into the locking slot, and cooperates with the locking slot to fix the cable hook, and the installation of the cable hook is completed;

[0076] After the cable hook is installed, the fixing plate is attached to the top surface of the cable trough, and the back of the cable hook is attached to the inner wall of the cable trough. The specific structure is as follows: Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the nails on the fixing plate are driven into the concrete blocks on both sides of the cable trough by a nail gun to achieve a fixed connection.

[0077] The present invention realizes the corner installation of the clamp by folding the fixing plate, which not only optimizes the stress condition of the whole device, reduces the force it receives, and enhances the connection stability of the device, but also can operate the tool outside the cable trough for installation operation, and the installation operation is convenient. After installation, the bottom of the cable trough is in an empty state, so it will not hinder the smooth discharge of foreign matter in the trough, which greatly facilitates the subsequent maintenance and inspection. At the same time, after various cables are installed on the clamp described in the present invention, the chaotic cables in the cable trough are sorted out, and there is sufficient isolation space between cables. It can not only effectively isolate different cables, but also the cables are clearly layered, which greatly improves the cable search efficiency, and the cables are more beautiful after installation. The present invention has the advantages of both floor-standing brackets and wall-mounted brackets while overcoming their respective shortcomings, greatly improving the efficiency and quality of railway cable laying construction.

[0078] At the same time, the present invention also realizes the fastening and limiting of the cable hook in 6 degrees of freedom directions through elastic locks and multiple clamps, which can effectively prevent the cable hook from being separated from the hook connecting plate during cable vibration, thereby improving the stability and reliability of the isolation fixture; the cable hook and the fixing plate can be installed by sliding, and the installation method is simple and maintenance is convenient, which greatly improves the installation efficiency of the equipment.
