Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically to a cable laying mechanism for low-voltage engineering. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories according to the power transmission capacity: high-voltage and low-voltage. The electrical power used in buildings and building complexes generally refers to AC 220V 50Hz and below low-voltage electricity. During the construction of low-voltage electrical engineering, cables need to be laid, so cable laying mechanisms are required to perform the cable laying operation.

[0003] Currently used cable laying mechanisms typically involve simply winding the cable with a take-up roller. During operation, the take-up roller is driven by a motor to rotate and unwind the cable. This method makes it difficult to adjust the laying position, and friction may occur between the cable and objects in front of the laying point, causing cable wear and affecting the quality of cable laying.

[0004] In view of this, this utility model proposes a low-voltage engineering cable laying mechanism that can adjust the laying position to solve this problem. Utility Model Content

[0007] The cable feeding assembly includes a drive roller and a support roller rotatably connected to the inner wall of the guide tube. The cable is clamped between the drive roller and the support roller. A first motor is fixedly installed on the front side of the guide tube to drive the drive roller to rotate and feed the cable.

[0008] The biasing assembly includes an adjustment box fixedly mounted on the surface of the fixed frame. A shaft is rotatably connected to the surface of the adjustment box. A guide tube is fixedly mounted on the surface of the shaft. An electric push rod is embedded at the bottom end of the adjustment box. The telescopic end of the electric push rod extends into the interior of the adjustment box and is fixedly mounted with a rack. The shaft extends into the interior of the adjustment box and is fixedly mounted with a gear plate. The rack meshes with the gear plate.

[0009] Furthermore, the surface of the mobile frame is provided with a first guide wheel, and cables are laid on the surface of the first guide wheel.

[0010] As a further description of the above technical solution: by setting a first guide wheel, the cable between the take-up roller and the guide tube can be guided and transported.

[0011] Furthermore, a second guide wheel is provided at both ends of the guide tube, and the cable is laid on the surface of the second guide wheel.

[0012] As a further description of the above technical solution: by setting a second guide wheel, the cables passing through both ends of the guide tube can be guided and transported, reducing wear between the cables and the guide tube.

[0013] Furthermore, a mobile power supply and a control panel are fixedly installed on the surface of the mobile frame, and the first motor and the electric push rod are electrically connected to the mobile power supply through the control panel.

[0014] Furthermore, the guide tube includes an outer tube and an inner tube, with the inner tube inserted at the end of the outer tube away from the shaft. An electric telescopic rod is fixedly installed on the surface of the outer tube, and the inner tube is fixed to the telescopic end of the electric telescopic rod.

[0015] As a further description of the above technical solution: Since the guide tube is composed of an inner tube and an outer tube, the length of the guide tube can be adjusted by controlling the extension of the electric telescopic rod, so as to facilitate further adjustment of the line laying height.

[0016] Furthermore, a rectangular rod is rotatably mounted on the surface of the support frame, and a second motor for driving the rectangular rod to rotate and take up the wire is coaxially fixed on the back of the support frame. The take-up roller is sleeved on the surface of the rectangular rod, and a cap is provided at the end of the rectangular rod away from the second motor. The cap is detachably mounted on the end of the rectangular rod by bolts.

[0017] As a further description of the above technical solution: When winding the cable, the second motor drives the winding roller to rotate, which can achieve the purpose of winding the cable. When it is necessary to replace the winding roller, the cap can be removed, and then the winding roller can be removed from the surface of the rectangular rod for replacement.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Compared with existing technologies, this low-voltage engineering cable laying mechanism utilizes a winding roller to wind and wrap the cable, and a mobile frame to move the entire cable. When cable laying is required, a first motor drives a drive roller to rotate. The clamping effect of the drive roller and support roller drives the cable to slide inside the guide tube, achieving the purpose of laying the cable. During laying, the electric push rod can be extended and retracted according to the external environment to move the rack. Based on the meshing of the rack and toothed disc, the shaft can be deflected to adjust the angle of the guide tube. This allows for adjustment of the cable laying height according to the external environment, facilitating avoidance of external objects, reducing wear between the cable and external objects during the laying process, and ensuring the quality of the project construction.

[0020] 2. Compared with existing technologies, this low-voltage engineering cable laying mechanism, by setting a first guide wheel, can guide and transport the cable between the take-up roller and the guide tube; by setting a second guide wheel, it can guide and transport the cable passing through both ends of the guide tube, reducing wear between the cable and the guide tube; since the guide tube is composed of an inner tube and an outer tube, the length of the guide tube can be adjusted by controlling the extension of the electric telescopic rod, which facilitates further adjustment of the laying height; when the cable is being wound up, the take-up roller is driven to rotate by a second motor, which can achieve the purpose of winding the cable; when the take-up roller needs to be replaced, the cap can be removed, and then the take-up roller can be removed from the surface of the rectangular rod for replacement.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cable laying mechanism for low-voltage engineering involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1 to 4 This utility model provides a cable laying mechanism for low-voltage engineering, including a mobile frame 1. The upper surface of the mobile frame 1 is respectively provided with a support frame 2 and a fixed frame 3. The surface of the support frame 2 is provided with a winding roller 4. The surface of the fixed frame 3 is provided with a guide tube 5. The inner cavity of the guide tube 5 is reserved with a cavity for the cable to pass through. The surface of the guide tube 5 is provided with a cable laying component. The surface of the fixed frame 3 is provided with an offset component corresponding to the guide tube 5.

[0028] The cable feeding assembly includes a drive roller 6 and a support roller 7 rotatably connected to the inner wall of the guide tube 5. The cable is clamped between the drive roller 6 and the support roller 7. A first motor 8 is fixedly installed on the front side of the guide tube 5 to drive the drive roller 6 to rotate and feed the cable.

[0029] The biasing assembly includes an adjustment box 9 fixedly mounted on the surface of the mounting bracket 3. A shaft 10 is rotatably connected to the surface of the adjustment box 9. A guide tube 5 is fixedly mounted on the surface of the shaft 10. An electric push rod 11 is embedded at the bottom end of the adjustment box 9. The telescopic end of the electric push rod 11 extends into the interior of the adjustment box 9 and is fixedly mounted with a rack 12. The shaft 10 extends into the interior of the adjustment box 9 and is fixedly mounted with a gear plate 13. The rack 12 meshes with the gear plate 13.

[0030] A mobile power supply 16 and a control panel 17 are fixedly installed on the surface of the mobile frame 1. The first motor 8 and the electric push rod 11 are electrically connected to the mobile power supply 16 through the control panel 17.

[0031] The cable laying mechanism for low-voltage engineering uses a winding roller 4 to wind and wrap the cable, and a moving frame 1 to move the entire cable. When it is necessary to lay the cable, the first motor 8 drives the drive roller 6 to rotate. The clamping effect of the drive roller 6 and the support roller 7 can drive the cable to slide inside the guide tube 5, thereby achieving the purpose of laying the cable.

[0032] It is worth noting that during cable laying, the electric push rod 11 can be extended and retracted to move the rack 12 according to the external environment. Based on the meshing of the rack 12 and the gear plate 13, the shaft 10 can be deflected to adjust the angle of the guide tube 5. This allows the cable laying height to be adjusted according to the external environment, making it easier to avoid external objects, reducing wear between the cable and external objects during the laying process, protecting the integrity of the cable, and thus ensuring the quality of the project construction.

[0033] The guide tube 5 includes an outer tube 18 and an inner tube 19. The inner tube 19 is inserted into the end of the outer tube 18 away from the shaft 10. An electric telescopic rod 20 is fixedly installed on the surface of the outer tube 18. The inner tube 19 is fixed to the telescopic end of the electric telescopic rod 20.

[0034] It is worth noting that since the guide tube 5 is composed of an inner tube 19 and an outer tube 18, the length of the guide tube 5 can be adjusted by controlling the extension of the electric telescopic rod 20, which facilitates further adjustment of the line laying height.

[0035] The surface of the mobile frame 1 is provided with a first guide wheel 14, and cables are laid on the surface of the first guide wheel 14.

[0036] Furthermore, by setting the first guide wheel 14, the cable between the take-up roller 4 and the guide tube 5 can be guided and transported.

[0037] Both ends of the guide tube 5 are provided with second guide wheels 15, and the cable is laid on the surface of the second guide wheels 15.

[0038] Furthermore, by setting a second guide wheel 15, the cables passing through both ends of the guide tube 5 can be guided and transported, reducing wear between the cables and the guide tube 5.

[0039] A rectangular rod 21 is rotatably mounted on the surface of the support frame 2, and a second motor 22 for driving the rectangular rod 21 to rotate and take up the wire is coaxially fixed on the back of the support frame 2. The take-up roller 4 is sleeved on the surface of the rectangular rod 21. A cap 23 is provided at the end of the rectangular rod 21 away from the second motor 22. The cap 23 is detachably mounted on the end of the rectangular rod 21 by bolts.

[0040] It is worth noting that when the cable is being wound up, the second motor 22 drives the winding roller 4 to rotate. At this time, the rotor of the first motor 8 is in a free state, which can achieve the purpose of winding up the cable. When the winding roller 4 needs to be replaced, the cap 23 can be removed, and then the winding roller 4 can be removed from the surface of the rectangular rod 21 for replacement.
