Description

Technical Field

[0001] This utility model relates to the field of cable channel construction technology, and specifically to a cable duct construction device. Background Technology

[0002] Currently, in the civil construction of cable channels, cable ducts and cable wells are usually poured separately. Typically, the cable well is poured first, followed by the cable duct. The cable duct is then constructed by reserving a square opening at the connection between the cable well and the cable duct, i.e., on the side wall of the end of the cable well. The size of the opening is usually larger than the outermost size of the duct group.

[0003] Pipe laying refers to the practice of burying pipes underground and then running cables through them. Pipes can be made of concrete, plastic, fiberglass, steel, etc., with sharp or rough edges. Pipe laying is preferred in areas with dense underground pipe networks and narrow urban roads where excavation is difficult.

[0004] Currently, most low-voltage power cable laying in the engineering field is done manually. During the cable laying process, the cable is easily damaged by factors such as dragging, friction, and machinery. When workers pull the cable, the cable bends down due to gravity at the entrance of the cable duct, which can cause the cable sheath to rub directly against the edge of the cable duct, resulting in wear of the cable sheath, a decrease in cable quality, and safety hazards. In addition, the cable is relatively heavy, and pulling it directly not only requires a lot of manpower, but also the greater the weight, the greater the friction and wear. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cable duct construction device that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a cable duct construction device, including a duct plate. A wire-passing hole is opened through one side of the duct plate. A fixed seat is detachably installed on the top of the duct plate. A second support rod is fixed to the top of one side of the fixed seat, and a first support rod is fixed to the top of the other side of the fixed seat. First connecting rods are fixed to both sides of the second support rod away from the fixed seat. Sleeve rods are fixed to the bottom of the opposite ends of the two first connecting rods. Lifting rods are movably sleeved inside the two sleeve rods. Connecting blocks are movably installed at the bottom of the two lifting rods. Support rollers are rotatably connected to the opposite sides of the two connecting blocks.

[0007] Furthermore, the fixing base is U-shaped, a spring is fixed to one side of the inner wall of the fixing base, a pressing plate is fixed to one end of the spring, the top of the pressing plate is parallel to the inner wall of the fixing base, and the bottom of the pressing plate is inclined.

[0008] Furthermore, the second support rod has a placement groove at its top, and the first support rod is used in conjunction with the placement groove. Both the first and second support rods have limit holes on their outer walls. There are multiple limit holes, which are arranged horizontally at equal intervals. One of the limit holes has a limit pin that is movably sleeved inside it.

[0009] Furthermore, both of the outer walls of the sleeve rods are threadedly connected to limit bolts at the bottom, and the limit bolts are in contact with one side of the lifting rod.

[0010] Furthermore, a torsion spring is provided on the inner wall of the lifting rod, the other end of the torsion spring is fixed to the top of the turntable, the turntable is rotatably connected to the bottom end of the lifting rod through a bearing, and the turntable is fixedly connected to the connecting block.

[0011] Furthermore, a first limiting block is fixed to the bottom of the outer wall of the sleeve rod, and a first limiting rod is fixed to the top of the outer wall of the turntable. The first limiting block and the first limiting rod are used together.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application installs a fixed seat on the top of each pipe laying plate and uses a limiting pin inserted into the limiting hole of the first support rod and the second support rod. The first support rod and the second support rod support the two fixed seats, making the fixed seats support the pipe laying plate more tightly. After adjusting the height of the support roller shaft, the cable is passed through the wire hole. The bottom of the cable can be placed on the top of the support roller shaft for rolling movement, thereby making the cable laying more convenient and reducing the external wear of the cable.

[0013] 2. This application connects the first support rod and the second support rod of two adjacent fixed seats, and then uses a limiting pin to insert into the limiting hole of the first support rod and the second support rod to support the pipe plate body with different spacing. The first support rod and the second support rod of two adjacent fixed seats are connected, and then a limiting pin is inserted into the limiting hole of the first support rod and the second support rod to support the wire hole 2 of different heights, thereby achieving the effect of laying pipes of various sizes.

[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0019] This application discloses a cable duct construction device, including a duct plate 1. A wire hole 2 is provided through one side of the duct plate 1. A fixing seat 3 is detachably installed on the top of the duct plate 1. A second support rod 7 is fixed to the top of one side of the fixing seat 3. A first support rod 6 is fixed to the top of the other side of the fixing seat 3. First connecting rods 10 are fixed to both sides of the second support rod 7 away from the fixing seat 3. Sleeve rods 11 are fixed to the bottom of the opposite ends of the two first connecting rods 10. Lifting rods 18 are movably sleeved inside the two sleeve rods 11. Connecting blocks 12 are movably installed at the bottom of the two lifting rods 18. Support roller shafts 13 are rotatably connected to the opposite sides of the two connecting blocks 12.

[0020] Reference Appendix Figure 2 The fixing seat 3 is U-shaped, and a spring 4 is fixed to one side of the inner wall of the fixing seat 3. A pressing plate 5 is fixed to one end of the spring 4. The top of the pressing plate 5 is parallel to the inner wall of the fixing seat 3, and the bottom of the pressing plate 5 is inclined. The pressing plate 5 is supported by the spring 4, so that the pressing plate 5 and the fixing seat 3 can be tightly fitted to the top of the pipe plate 1. The bottom of the pressing plate 5 is inclined, so when the fixing seat 3 is connected to the pipe plate 1, the fixing seat and the pipe plate 1 can be directly pressed together by the top of the pressing plate 5.

[0021] Reference Appendix Figure 1 The second support rod 7 has a placement groove at its top, and the first support rod 6 is used in conjunction with the placement groove. Both the first support rod 6 and the second support rod 7 have limit holes 8 on their outer walls. There are multiple limit holes 8, which are arranged horizontally at equal intervals. One of the limit holes 8 is fitted with a limit pin 9 through it. The first support rod 6 and the second support rod 7 of two adjacent fixed seats 3 are connected. The limit pin 9 is then inserted into the limit hole 8 of the first support rod 6 and the second support rod 7. The first support rod 6 and the second support rod 7 support the two fixed seats 3, making the fixed seats 3 more tightly supported on the pipe plate 1. When the spacing of the pipe plate 1 changes, the position of the limit holes 8 of the first support rod 6 and the second support rod 7 can be adjusted.

[0022] Reference Appendix Figure 4 Both sleeve rods 11 have threaded connections to the bottom of their outer walls, with limit bolts 15 inserted through them. The limit bolts 15 are connected to one side of the lifting rod 18. The horizontal height of the support roller shaft 13 is adjusted by moving the lifting rod 18 up and down inside the sleeve rod 11. The support roller shaft 13 is adjusted to the bottom of the wire hole 2, and then the position of the lifting rod 18 is fixed by tightening the limit bolts 15. When threading the cable later, the bottom of the cable can be placed on the top of the support roller shaft 13 after passing through the wire hole 2.

[0023] Reference Appendix Figure 5The inner wall of the lifting rod 18 is provided with a torsion spring, and the other end of the torsion spring is fixed to the top of the turntable 14. The turntable 14 is rotatably connected to the bottom end of the lifting rod 18 through a bearing. The turntable 14 is fixedly connected to the connecting block 12. The turntable 14 is connected by the torsion spring so that when the turntable 14 is not subjected to external force, the support roller shaft 13 can be kept perpendicular to one side of the lifting rod 18, and the two support roller shafts 13 are kept parallel. When not subjected to external force, the support roller shaft 13 can support the cable.

[0024] Reference Appendix Figure 4 The first limiting block 16 is fixed to the bottom of the outer wall of the sleeve rod 11, and the first limiting rod 17 is fixed to the top of the outer wall of the turntable 14. The first limiting block 16 and the first limiting rod 17 are used together. When the first limiting block 16 and the first limiting rod 17 are in contact with each other, the angle of the turntable 14 will not continue to change, and the angle of the supporting roller 13 will not continue to change when the cable support moves in the future.

[0025] The workflow of this utility model is as follows: First, install the cable tray 1 according to the cable laying requirements. Then, install the fixing seat 3 on the top of each cable tray 1. The pressing plate 5 is supported by the spring 4, so that the pressing plate 5 and the fixing seat 3 can fit tightly with the top of the cable tray 1. The bottom of the pressing plate 5 is set in an inclined shape. When connecting the fixing seat 3 to the cable tray 1, the fixing seat can be directly pressed to the cable tray 1. The pressing is done by the top of the pressing plate 5. Then, connect the first support rod 6 and the second support rod 7 of the two adjacent fixing seats 3. Then, use the limiting pin 9 to insert into the limiting hole 8 of the first support rod 6 and the second support rod 7. The first support rod 6 and the second support rod 7 support the two fixing seats 3 with each other, so that the fixing seats 3 are more tightly supported on the cable tray 1. When the spacing of the cable tray 1 changes, the position of the limiting hole 8 of the first support rod 6 and the second support rod 7 can be adjusted. Next, adjust the position of the support roller shaft 13 according to the position of the wire hole 2 as needed. Adjust the horizontal height of the support roller shaft 13 by moving the lifting rod 18 up and down inside the sleeve rod 11. Adjust the support roller shaft 13 to the bottom of the wire hole 2. Then, use the limit bolt 15 to tighten and fix the position of the lifting rod 18. Finally, pass the cable through the wire hole 2. The bottom of the cable can be placed on the top of the support roller shaft 13. With the cooperation of the first limit block 16 and the first limit rod 17, when the two touch each other, the angle of the turntable 14 will not continue to change. When the cable is moved in the subsequent support, the angle of the support roller shaft 13 will not continue to change. After installation, adjust the angle of the support roller shaft 13 and move it upward to remove the fixing seat 3. The support roller shaft 13 can then be taken out from the gap between the two cables.
