Description

Technical Field

[0001] The present invention relates to the technical field of cable bridges, and in particular to an adaptive telescopic bridge and an assembly structure thereof. Background Art

[0002] A cable tray is a structure composed of brackets, supports, and mounting accessories used to support and protect cables. It provides crucial support for laying cables within various buildings, allowing them to be arranged neatly and orderly, facilitating subsequent maintenance, inspection, and management.

[0003] During the use of existing bridges, due to the fixed length of the bridge, it is often encountered that the bridge length does not match the actual laying distance. Either the bridge length is too long or too short, resulting in uneven cable laying or unreasonable layout, or additional bridge sections need to be spliced ​​to change its length, which increases construction difficulty and cost.

[0004] The authorization announcement number is CN221812260U, which is an easy-to-splice fireproof trough cable tray. It includes a shell and a cover plate. The front and rear ends of the upper side of the shell are fixedly connected with threaded rods at equal distances. The outer side of the threaded rod is connected to a cylinder. The inner and outer ends of the shell are connected with a splicing mechanism. The splicing mechanism includes a splicing unit and a fireproof unit. When the length of this cable tray needs to be adjusted, one shell needs to be placed on the right end of the other shell. At the same time, the fixed block on the outer side of the shell at the right end slides to the inner side of the connection frame on the outer side of the shell at the left end, and then the plug is rebounded by the spring. The rod is pushed out of the circular groove, and at the same time, the end of the rod away from the spring is moved to the jacks at the upper and lower ends of the connecting frame to fix the two shells to each other. Then, the shells corresponding to the required length are spliced ​​in this way to achieve the effect of convenient splicing and fixing. However, the bridge changes its length by splicing multiple shells one by one. The minimum unit of length adjustment each time is a complete shell length, and continuous and fine length adjustment cannot be achieved. When facing non-standard length requirements, the spliced ​​bridge is prone to being too long or too short, and cannot accurately meet the actual laying requirements.

[0005] Therefore, it is necessary to invent an adaptive telescopic bridge and its assembly structure to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an adaptive telescopic bridge and its assembly structure to solve the problems that the bridge length is fixed and the length needs to be changed by splicing multiple shells one by one, which increases the construction difficulty and cost.

[0007] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adaptive telescopic bridge frame and its assembly structure, including a bridge frame connecting seat, a movable connecting frame, a connecting bridge frame and a telescopic adjustment frame. The four end portions of the bridge frame connecting seat can be detachably connected with the movable connecting frame, one end of the movable connecting frame is hinged with the connecting bridge frame, and one end of the connecting bridge frame is slidably connected with the telescopic adjustment frame. The outer walls of the front and rear ends of the connecting bridge frame are provided with guide rails, and the contact position between the inner wall of the telescopic adjustment frame and the guide rail is provided with a guide slide groove matching therewith. Insert rods are provided at the four corners of the side wall of the bridge frame connecting seat, and the contact position of the movable connecting frame corresponding to the insert rod is provided with a slot matching therewith. A reinforcement mechanism is provided on the outer side of the connection between the bridge frame connecting seat and the movable connecting frame.

[0008] Furthermore, the hinged structure between the movable connecting frame and the connecting bridge frame is a rotatable connecting structure, so that the connecting bridge frame can be adjusted in angle relative to the movable connecting frame.

[0009] Furthermore, fixing plates are provided at the upper and lower ends of one side of the telescopic adjustment frame, and limiting bolts are connected through the fixing plates, so that the fixing plates provide a certain supporting capacity for the limiting bolts.

[0010] Furthermore, the limiting bolt extends to the inside of the connecting bridge, and a plurality of limiting screw holes are distributed in an equidistant array on the upper and lower surfaces of the connecting bridge. The inner wall threads of the plurality of limiting screw holes are adapted to the outer wall threads of the limiting bolts. By cooperating with the limiting screw holes at different positions, the telescopic position of the telescopic adjustment frame on the connecting bridge can be fixed.

[0011] Furthermore, extension plates are provided on the four sides of one end of the movable connecting frame, and matching grooves are provided at the contact positions of the bridge connecting seat corresponding to the extension plates. The cooperation between the extension plates and the grooves enhances the stability of the connection between the bridge connecting seat and the movable connecting frame.

[0012] Furthermore, the reinforcement mechanism includes a reinforcement frame located outside the movable connecting frame, and sliders are provided on the four sides of the inner wall of the reinforcement frame. A No. 1 slide groove is provided at the contact position between the four sides of the outer wall of the movable connecting frame and the slider, so that the reinforcement frame can slide to the connection position inside the No. 1 slide groove.

[0013] Furthermore, a second sliding groove is provided at the contact position between the slider and the four sides of the outer wall of the bridge connecting seat to facilitate the reinforcement frame to slide inside the second sliding groove to the connection position.

[0014] Furthermore, reinforcement bolts are passed through the center positions of the four sides of the reinforcement frame and extend into the interior of the groove. Reinforcement screw holes matching the groove and the reinforcement bolts are provided at the contact position between the groove and the reinforcement bolts. The connection between the bridge connecting seat and the movable connecting frame is reinforced by the cooperation between the reinforcement bolts and the reinforcement screw holes.

[0015] Furthermore, the bridge frame connecting seat and the movable connecting frame are connected by plugging the rod into the slot, and then the extension plate is inserted into the groove, the reinforcement mechanism is installed and fixed by the reinforcement bolts, the connecting bridge frame and the movable connecting frame are hinged, the telescopic adjustment frame is slidably connected to one end of the connecting bridge frame by the cooperation of the guide slide rail and the guide slide groove, and the telescopic position is fixed by the cooperation of the limit bolt and the limit screw hole.

[0016] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0017] 1. The four ends of the bridge connecting seat of the present invention can be detachably connected to the movable connecting frames. Users can flexibly choose to install or disassemble the movable connecting frames according to actual needs. For example, in a large factory building with relatively open space, a bridge may be required for laying cables in multiple directions and with multiple branches. In this case, the user can install movable connecting frames at all four ends of the bridge connecting seat according to actual direction requirements to build a complex and orderly bridge network. In some small places with limited space or a relatively single cable direction, the user can choose to install movable connecting frames at only one or both ends to meet basic cable support and laying requirements. This structural design realizes the flexible assembly of the bridge in different scenarios, thereby improving the applicability and versatility of the bridge.

[0018] 2. The bridge of the present invention can realize the telescopic function by sliding the telescopic adjustment frame on the connecting bridge, and can be adaptively adjusted according to the length requirements of cable laying, avoiding the inconvenience caused by the fixed length of traditional bridges or the need to splice and adjust the length. At the same time, combined with the cooperation of the limit bolts and the limit screw holes, the telescopic position can be accurately fixed to ensure the stability of the bridge structure.

[0036] Example 1

[0037] like Figure 1-5 As shown, the present invention is an adaptive telescopic bridge and its assembly structure, including a bridge connecting seat 1, a movable connecting frame 2, a connecting bridge 3 and a telescopic adjustment frame 4. The four ends of the bridge connecting seat 1 can be detachably connected with the movable connecting frame 2, one end of the movable connecting frame 2 is hinged with the connecting bridge 3, the hinge structure of the movable connecting frame 2 and the connecting bridge 3 is a rotatable connection structure, one end of the connecting bridge 3 is slidably connected with the telescopic adjustment frame 4, the outer walls of the front and rear ends of the connecting bridge 3 are provided with guide rails 5, and the contact position between the inner wall of the telescopic adjustment frame 4 and the guide rail 5 is provided with a guide groove 6 matching therewith, and the upper and lower ends of one side of the telescopic adjustment frame 4 are provided with a fixing plate 7, and a limiting bolt 8 is connected through the fixing plate 7, and the limiting bolt 8 extends to the inside of the connecting bridge 3, and a plurality of limiting screw holes 9 are equidistantly distributed in an array on the upper and lower surfaces of the connecting bridge 3, and the inner wall threads of the plurality of limiting screw holes 9 are adapted to the outer wall threads of the limiting bolt 8.

[0038] In this embodiment, the four ends of the bridge connecting seat 1 can be disassembled and connected to the movable connecting frame 2, so that the user can flexibly choose the installation quantity and position of the movable connecting frame 2 according to the actual scene requirements. In multi-directional and multi-branch cable laying scenarios such as large factories, multiple movable connecting frames 2 can be installed to build a complex and orderly bridge network; in small places with limited space or a single cable direction, only a small number of movable connecting frames 2 can be installed to meet the basic cable support and laying needs, which greatly improves the applicability and versatility of the bridge. The rotatable hinged structure between the movable connecting frame 2 and the connecting bridge 3 enables the connecting bridge 3 to be adjusted in angle according to the actual direction of the cable, and the sliding function of the telescopic adjustment frame 4 on the connecting bridge 3 enables the bridge to be adaptively adjusted according to the length requirements of the cable laying. At the same time, the cooperation of the limit bolt 8 and the limit screw hole 9 can accurately fix the telescopic position of the telescopic adjustment frame 4. After the telescopic adjustment frame 4 slides to the appropriate position, it is firmly fixed to the connecting bridge 3 by tightening the limit bolt 8 to prevent the telescopic adjustment frame 4 from sliding or displacing during use, ensuring the stability of the bridge structure and providing reliable support and protection for the cables.

[0039] Example 2

[0040] like Figure 6-9 As shown, the four corners of the side wall of the bridge connecting seat 1 are provided with an insertion rod 10, and the movable connecting frame 2 is provided with a matching slot 11 at the contact position corresponding to the insertion rod 10. A reinforcement mechanism 14 is provided on the outside of the connection between the bridge connecting seat 1 and the movable connecting frame 2, and an extension plate 12 is provided on the four sides of one end of the movable connecting frame 2. The bridge connecting seat 1 is provided with a matching groove 13 at the contact position corresponding to the extension plate 12. The reinforcement mechanism 14 includes a reinforcement frame 1401 located on the outside of the movable connecting frame 2, and the reinforcement frame 1401 Sliders 1402 are provided on the four sides of the inner wall, and matching slide grooves 1403 are provided at the contact positions between the four sides of the outer wall of the movable connecting frame 2 and the slider 1402, and matching slide grooves 1404 are provided at the contact positions between the slider 1402 and the four sides of the outer wall of the bridge frame connecting seat 1. Reinforcement bolts 1405 pass through the center positions of the four sides of the reinforcement frame 1401 and extend to the inside of the groove 13, and matching reinforcement screw holes 1406 are provided at the contact positions between the groove 13 and the reinforcement bolts 1405.

[0041] In this embodiment, the plug rods 10 at the four corners of the side wall of the bridge connecting seat 1 match the slots 11 at the corresponding positions of the movable connecting frame 2. This plug-in structure increases the connection points between the bridge connecting seat 1 and the movable connecting frame 2, making the connection between the two more secure, and the extension plates 12 on the four sides of one end of the movable connecting frame 2 are inserted into the corresponding grooves 13 of the bridge connecting seat 1, further expanding the contact area of ​​the connection part, enhancing the tightness and stability of the connection, and the reinforcement mechanism 14 is through the reinforcement frame 1401, the slider 1402, the first slide 1403, the second slide 1 404. The synergistic effect of the reinforcement bolts 1405 and the reinforcement screw holes 1406 provides additional reinforcement for the connection between the bridge connecting seat 1 and the movable connecting frame 2. At the same time, the reinforcement bolts 1405 are screwed into the reinforcement screw holes 1406 to tightly connect the reinforcement frame 1401 and the bridge connecting seat 1, further enhancing the strength and stability of the connection. Even if the bridge is subjected to vibration, pulling and other forces of the cable during long-term use, the reinforcement mechanism 14 can ensure that the connection part will not loosen, thereby ensuring the normal use of the bridge and the safe transmission of the cable.

[0042] The bridge connecting seat 1 and the movable connecting frame 2 are connected by plugging the rod 10 with the slot 11, and then the extension plate 12 is inserted into the groove 13, the reinforcement mechanism 14 is installed and fixed by the reinforcement bolt 1405, the connecting bridge 3 and the movable connecting frame 2 are hinged, the telescopic adjustment frame 4 is slidably connected to one end of the connecting bridge 3 by the cooperation of the guide rail 5 and the guide slide groove 6, and the telescopic position is fixed by the cooperation of the limit bolt 8 and the limit screw hole 9.

[0043] Working principle of the present invention:

When the plug rod 10 is fully inserted into the slots 11, the extension plate 12 can also be accurately aligned with the embedded groove 13, and then adjust the position of the reinforcement frame 1401 so that the sliders 1402 on the four sides of the inner wall of the reinforcement frame 1401 are respectively aligned with the No. 1 slide grooves 1403 on the four sides of the outer wall of the movable connecting frame 2 and the bridge The second slide groove 1404 on the four sides of the outer wall of the connecting seat 1 is slowly pushed along the direction of the first slide groove 1403 and the second slide groove 1404, so that the position of the reinforcement frame 1401 is just aligned with the connection end of the bridge connecting seat 1 and the movable connecting frame 2, and then the four-sided reinforcement bolts 1405 are screwed in from the center position of the four sides of the reinforcement frame 1401 in sequence, and the reinforcement bolts 1405 are continuously tightened until they are screwed into the reinforcement screw holes 1406 in the groove 13, and the reinforcement frame 1401 and the bridge connecting seat 1 are tightly connected together through threaded engagement;

[0045] When the length of the bridge needs to be adjusted, slowly push the telescopic adjustment frame 4 along the direction of the guide rail 5 to make it slide on the connecting bridge 3. When the telescopic adjustment frame 4 slides to the appropriate position, pick up the limit bolt 8 on the fixing plate 7 and slowly tighten the limit bolt 8 so that it is threadedly engaged with one of the limit screw holes 9 equidistantly distributed in the upper and lower surfaces of the connecting bridge 3 to ensure that the limit bolt 8 can firmly fix the telescopic adjustment frame 4 to prevent it from sliding or displacement during subsequent use.
