Description

Technical Field

[0001] This utility model belongs to the field of municipal construction technology, specifically, it relates to an auxiliary guide structure for laying municipal cables. Background Technology

[0002] Municipal cables play a crucial role in urban infrastructure construction. They mainly include various types such as power cables, communication cables, and optical cables, and are responsible for important functions such as power transmission, information communication, and the transmission of various types of data.

[0003] When laying municipal cables, they are usually laid along pre-planned routes that often cross city streets, between buildings, underground pipes, and bridges. Typically, trenches are dug or existing underground pipe systems are utilized before the cables are carefully placed within them.

[0004] However, when municipal cables encounter corners during installation, the cables need to be bent to adapt to the changing angles. This bending process can easily damage the cables. The main reason is that cables have inherent physical properties, containing structures such as metal conductors, insulation layers, and sheaths. Excessive bending can subject these structures to stresses exceeding their design limits. Metal conductors may deform or break, insulation layers may crack, compromising their insulation performance, and the sheath may tear, reducing the cable's protective capabilities. Damaged cables directly affect the stability of power transmission and the quality of communication signals, potentially leading to power outages, communication disruptions, or signal interference. This causes significant inconvenience to urban residents, businesses, and the normal operation of various municipal facilities.

[0005] To address the aforementioned issues, this application proposes an auxiliary guiding structure for municipal cable laying. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an auxiliary guide structure for laying municipal cables to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A municipal cable laying auxiliary guide structure includes a mounting frame, an extension block, and a guide block, wherein...

[0009] The outer side wall of the mounting bracket is rotatably connected to a first adjusting rod, and the outer side wall of the mounting bracket is rotatably connected to a second adjusting rod. The ends of the first adjusting rod and the second adjusting rod away from the mounting bracket are respectively fixedly connected to the inner side wall of the expansion block. The inner side wall of the expansion block is slidably connected to the outer side wall of the guide block.

[0010] The inner wall of the mounting bracket is rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a gear, the outer wall of the rotating rod is fixedly connected to a support plate, the top and bottom of the support plate are rotatably connected to connecting rods, and the ends of the two connecting rods away from the support plate are rotatably connected to the outer walls of the first adjusting rod and the second adjusting rod, respectively.

[0011] The mounting bracket has a sliding groove on its inner side wall. A movable plate is slidably connected to the mounting bracket through the sliding groove. A first threaded rod is rotatably connected to the inner side wall of the mounting bracket. The inner side wall of the movable plate is threadedly connected to the outer side wall of the first threaded rod. A toothed plate is fixedly connected to the outer side wall of the movable plate. The outer side wall of the toothed plate meshes with a gear.

[0012] Preferably, it further includes a fixing plate fixedly connected to the outer wall of the guide block. The outer wall of the fixing plate is rotatably connected to a second threaded rod. The outer wall of the second threaded rod is threadedly connected to a pressing block. The outer wall of the pressing block is fixedly connected to a rubber pad. The cross-section of the rubber pad is trapezoidal. By setting the second threaded rod, it is convenient to adjust the height of the pressing block and the rubber pad.

[0013] Preferably, the device also includes a support seat movably disposed outside the rubber pad. The support seat has a trapezoidal cross-section, and the rubber pad is located inside the support seat. By providing the support seat, it is convenient for operators to fix the equipment.

[0014] Preferably, it also includes a roller rotatably connected to the inner sidewall of the expansion block. The inner sidewall of the guide block is provided with a guide groove, the roller is located inside the guide groove, and the outer sidewall of the roller is in contact with the inner sidewall of the guide block to limit the travel path of the expansion block. By setting the roller, it is easy to limit the travel path of the expansion block and avoid the horizontal position of the expansion block and the roller being misaligned during the movement.

[0015] Preferably, the centerline extension of the roller coincides with the center of the cross-section of the expansion block. By setting the centerline extension of the roller to coincide with the center of the cross-section of the expansion block, the roller is prevented from getting stuck while following the expansion block.

[0016] Preferably, it also includes a vertical rod fixedly connected to the bottom of the fixed plate. The outer wall of the vertical rod is slidably connected to the extrusion block. By setting the vertical rod, it is easy to restrict the extrusion block and prevent the extrusion block from rotating synchronously with the second threaded rod.

[0017] Preferably, it also includes a limiting rod fixedly connected to the outer wall of the mounting frame. The outer wall of the toothed plate has a limiting groove, and the limiting rod is located inside the limiting groove to limit the travel path of the toothed plate. By setting the limiting groove and the limiting rod, the toothed plate is prevented from disengaging from the gear during travel.

[0018] In summary, the technical effects and advantages of this utility model are as follows: This municipal cable laying auxiliary guide structure, through the coordinated use of a first adjusting rod, a second adjusting rod, a rotating rod, a sliding groove, a moving plate, a first threaded rod, a toothed plate, a gear, a support plate, a connecting rod, an extension block, and a guide block, facilitates operators to adjust the bending angle of the cable according to the required bending angle at the laying site. This avoids excessive bending during cable laying, thereby preventing the metal conductors inside the cable from bearing stress exceeding their design limits, preventing cable damage, and ultimately avoiding affecting the stability of power transmission and the quality of communication signals.

Operators can adjust the horizontal height of the equipment and the direction of the guide block according to the site environment, thereby improving the adaptability of the equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-4A municipal cable laying auxiliary guide structure includes a mounting frame 1, an extension block 12, and a guide block 14, wherein...

[0029] The outer side wall of the mounting bracket 1 is rotatably connected to a first adjusting rod 2, and the outer side wall of the mounting bracket 1 is rotatably connected to a second adjusting rod 3. The ends of the first adjusting rod 2 and the second adjusting rod 3 away from the mounting bracket 1 are respectively fixedly connected to the inner side wall of the expansion block 12. The expansion block 12 is divided into two parts along the center line. The first adjusting rod 2 and the second adjusting rod 3 are respectively fixedly connected to the inner side wall of one of the expansion blocks 12. The two inner side walls of the expansion block 12 are respectively slidably connected to the outer side wall of the guide block 14.

[0030] The inner wall of the mounting bracket 1 is rotatably connected to a rotating rod 4, and the outer wall of the rotating rod 4 is fixedly connected to a gear 9. There are two gears 9, which are located at the two ends of the rotating rod 4. The outer wall of the rotating rod 4 is fixedly connected to a support plate 10. The cross-section of the support plate 10 is elliptical. The top and bottom of the support plate 10 are rotatably connected to connecting rods 11. The points where the two connecting rods 11 are rotatably connected to the support plate 10 are located at the two foci of the ellipse. The ends of the two connecting rods 11 away from the support plate 10 are rotatably connected to the outer walls of the first adjusting rod 2 and the second adjusting rod 3, respectively. Specifically, one connecting rod 11 is rotatably connected to the second adjusting rod 3, and the end of the connecting rod 11 away from the second adjusting rod 3 is located at the focal point of the support plate 10 away from the second adjusting rod 3. Similarly, the other connecting rod 11 is rotatably connected to the first adjusting rod 2, and the end of the connecting rod 11 away from the first adjusting rod 2 is located at the focal point of the support plate 10 away from the first adjusting rod 2.

[0031] The inner sidewall of the mounting bracket 1 is provided with a sliding groove 5. The mounting bracket 1 is slidably connected to a movable plate 6 through the sliding groove 5. The top and bottom of the movable plate 6 are respectively provided with protrusions, and the protrusions are all located inside the sliding groove 5. The inner sidewall of the mounting bracket 1 is rotatably connected to a first threaded rod 7. The end of the first threaded rod 7 away from the mounting bracket 1 is provided with a handle for easy rotation by the operator. The inner sidewall of the movable plate 6 is threadedly connected to the outer sidewall of the first threaded rod 7. The outer sidewall of the movable plate 6 is fixedly connected to a toothed plate 8. There are two toothed plates 8, and the outer sidewalls of the two toothed plates 8 respectively mesh with two gears 9.

[0032] In use, the operator can rotate the first threaded rod 7 according to the on-site construction environment. When the first threaded rod 7 rotates, since the first threaded rod 7 is threadedly connected to the movable plate 6, and the movable plate 6 is slidably connected inside the mounting bracket 1, the movable plate 6 can move horizontally along the first threaded rod 7 when the first threaded rod 7 is rotated. When the movable plate 6 gradually moves away from the first adjusting rod 2 and the second adjusting rod 3, the movable plate 6 pulls the two toothed plates 8 to move horizontally. Since the two toothed plates 8 are respectively engaged with the two gears 9, when the two toothed plates 8 move, they can drive the two gears 9 to rotate and drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it drives the gears 9 to rotate and drive the rotating rod 4 to rotate. The moving support plate 10 rotates synchronously. At this time, the two connecting rods 11 located at the top and bottom of the support plate 10 push the first adjusting rod 2 and the second adjusting rod 3 respectively, so that the included angle between the first adjusting rod 2 and the second adjusting rod 3 gradually increases, further driving the two parts of the expansion block 12 to gradually separate. Since the expansion block 12 is set outside the guide block 14, when the two parts of the expansion block 12 gradually separate, the guide block 14 fills the space between the two parts of the expansion block 12 to form a complete arc. At this time, the expansion block 12 and the guide block 14 can abut against the bending part of the cable to avoid the cable bending too much and causing cable damage.

[0033] Reference Figure 1 , Figure 2 and Figure 4 It also includes a fixing plate 16 fixedly connected to the outer wall of the guide block 14. A second threaded rod 17 is rotatably connected through the outer wall of the fixing plate 16. The relative position between the second threaded rod 17 and the fixing plate 16 is fixed, that is, the position between the second threaded rod 17 and the fixing plate 16 remains unchanged when the second threaded rod 17 rotates. A pressing block 19 is threadedly connected to the outer wall of the second threaded rod 17. A rubber pad 20 is fixedly connected to the outer wall of the pressing block 19. The cross-section of the rubber pad 20 is trapezoidal. It also includes a support seat 21 movably disposed outside the rubber pad 20. The cross-section of the support seat 21 is trapezoidal, and the rubber pad 20 is located inside the support seat 21. It also includes a vertical rod 18 fixedly connected to the bottom of the fixing plate 16. The outer wall of the vertical rod 18 is connected to the pressing block 14. 9. A through-sliding connection is used. The bottom of the support base 21 is provided with positioning holes around its perimeter. Construction personnel can fix the support base 21 in a certain position through multiple positioning holes. At this time, the second threaded rod 17 is rotated, which drives the extrusion block 19 to reciprocate along the second threaded rod 17. The upright rod 18 restricts the position of the extrusion block 19, so that the extrusion block 19 cannot rotate with the rotation of the second threaded rod 17. When the extrusion block 19 is raised, it drives the rubber pad 20 to be raised synchronously. At this time, the outer wall of the rubber pad 20 gradually fits against the inner wall of the support base 21. As the second threaded rod 17 rotates, the outer wall of the rubber pad 20 and the inner wall of the support base 21 gradually become more tightly fitted, thereby fixing and installing the equipment.

[0034] Reference Figure 1 , Figure 2 and Figure 4 It also includes rollers 13 rotatably connected to the inner wall of the expansion block 12. There are two rollers 13, which are located inside two parts of the expansion block 12 respectively. The inner wall of the guide block 14 is provided with guide grooves 15, which are also provided with two guide grooves. The two rollers 13 are located inside the two guide grooves 15 respectively, and the outer walls of the two rollers 13 are respectively in contact with the inner wall of the guide block 14 to limit the travel path of the expansion block 12. The extended part of the center line of the two rollers 13 coincides with the center of the cross-section of the expansion block 12. The two rollers 13 play a guiding and supporting role, which makes it easy for the expansion block 12 to move along the predetermined path during the rotation and unfolding process, and prevents deviation or jamming.

[0035] Reference Figure 4 It also includes a limiting rod 23 fixedly connected to the outer wall of the mounting frame 1. There are two limiting rods 23, which are located on the top outer wall and bottom outer wall of the mounting frame 1, respectively. The outer walls of the two toothed plates 8 are provided with limiting grooves 22, and the two limiting rods 23 are located inside the two limiting grooves 22, respectively, to limit the travel path of the toothed plates 8.

[0036] Working principle: Construction personnel can fix the support base 21 in a certain position through multiple positioning holes. At this time, the second threaded rod 17 is rotated, which drives the extrusion block 19 to reciprocate along the second threaded rod 17. The upright rod 18 restricts the position of the extrusion block 19, so that the extrusion block 19 cannot rotate with the rotation of the second threaded rod 17. When the extrusion block 19 is raised, it drives the rubber pad 20 to rise synchronously. At this time, the outer wall of the rubber pad 20 gradually fits against the inner wall of the support base 21. As the second threaded rod 17 rotates, the outer wall of the rubber pad 20 and the inner wall of the support base 21 gradually become more tightly fitted, thereby fixing the equipment. The operator can rotate the first threaded rod 7 according to the on-site construction environment. When the first threaded rod 7 is rotated, since the first threaded rod 7 is threadedly connected to the moving plate 6 and the moving plate 6 is slidably connected inside the mounting frame 1, the moving plate 6 can move horizontally along the first threaded rod 7 when the first threaded rod 7 is rotated. As the moving plate 6 gradually moves away from the first adjusting rod 2 and the second adjusting rod 3, the moving plate 6 pulls the two toothed plates 8 to make horizontal displacement. Since the two toothed plates 8 are engaged with the two gears 9 respectively, when the two toothed plates 8 move, they can drive the two gears 9 to rotate and drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it drives the support plate 10 to rotate synchronously. At this time, the two connecting rods 11 located at the top and bottom of the support plate 10 push the first adjusting rod 2 and the second adjusting rod 3 respectively, so that the included angle between the first adjusting rod 2 and the second adjusting rod 3 gradually increases, further driving the two parts of the expansion block 12 to gradually separate. Since the expansion block 12 is set outside the guide block 14, when the two parts of the expansion block 12 gradually separate, the guide block 14 fills the space between the two parts of the expansion block 12 to form a complete arc. At this time, the expansion block 12 and the guide block 14 can abut against the bending part of the cable to avoid the cable bending too much and causing cable damage.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
