Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, and specifically relates to an electrical engineering cable protection structure. Background Technology

[0002] Electric wires and cables serve multiple functions, including transmitting electrical energy, generating magnetic fields, transmitting information, conveying data and images, and enabling monitoring. They are indispensable electrical products in industrial production and modern service industries, often used for control installations, equipment connections, and power transmission. When cables pass through the metal sheath of electrical cabinets, their insulation may be damaged, posing a risk of cable cuts, which can lead to insulation failure and leakage. To address these issues, technicians often use cable protection conduits to protect cables.

[0003] A search revealed a novel cable protection device disclosed in patent CN222016104U. This device involves placing the cable inside a slot, covering it with a protective shell, and then allowing ventilation through air holes. However, this solution has certain shortcomings in practical use. While the cable clamping method is horizontal, in reality, the cable's path is not straight but rather curves around obstacles, making it prone to damage at bends. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrical engineering cable protection structure to solve the problem that cables are easily damaged when encountering bends during the installation process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical engineering cable protection structure, including an angle adjustment mechanism and a cable clamping structure. The angle adjustment mechanism includes a drive platform, with an inspection cover movably engaged at the top of the drive platform. A screw is rotatably connected to the inner side of the drive platform via a built-in motor. A nut seat is threadedly connected to the surface of the screw, and a hinge rod is rotatably connected to the top of the nut seat.

[0006] The cable clamping structure includes a cable pass-through box and a protective cover. The bottom end of the cable pass-through box is hinged to the end of the hinge rod away from the nut seat. The cable pass-through box has a pass-through port on both the front and back sides. A fixing device is fixedly installed inside the cable pass-through box.

[0007] The fixing device includes a vertical plate with a vertical groove on the front side. A rotating arm is slidably connected inside the vertical groove. Two clamping claws are hinged to the top of the rotating arm. An electro-hydraulic push rod is fixedly installed at the top of the vertical plate, and the movable end of the electro-hydraulic push rod is fixedly connected to the clamping claw on the left side.

[0008] More preferably, the inspection cover has a through opening inside, and the hinge rod extends through the through opening to the top of the inspection cover.

[0009] More preferably, a toothed ring is fixedly sleeved on the surface of the screw, and a rack is movably connected to the inner wall of the drive platform via an electric telescopic rod, the rack and the toothed ring meshing with each other.

[0010] More preferably, a hinge seat is fixedly connected to the bottom end of the cable conduit box, and the cable conduit box is rotatably connected to the notch of the drive platform through the hinge seat.

[0011] More preferably, a slider is installed at the bottom end of the gripping claw, and the slider is slidably connected to a groove opened at the top of the vertical plate.

[0012] More preferably, a contact pad is provided on the inner side of the gripping claw, and the contact pad is a sponge pad.

[0013] Compared with the prior art, the electrical engineering cable protection structure provided by this utility model has the following beneficial effects:

[0014] (1) The electrical engineering cable protection structure is equipped with an angle adjustment mechanism. The built-in motor drives the nut seat to rotate the hinge rod through the screw, so that the top of the hinge rod drives the cable clamping structure to adjust the angle, thereby adjusting the bending angle of the corresponding cable during the installation process. This avoids damage to the cable caused by excessive bending angle during the installation process, and ensures that the cable can avoid obstacles during the installation process and reduce the phenomenon of cable damage during the installation process, thus effectively protecting the cable.

[0015] (2) The electrical engineering cable protection structure, by setting a cable clamping structure, can use multiple sets of fixing devices inside the cable box to assist in clamping the cable, so that the structure can be adapted to the diameter of the cable, thereby improving the versatility of the protection structure and enabling it to be used for cables of different sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses an electrical engineering cable protection structure, including an angle adjustment mechanism 1 and a cable clamping structure 2. The angle adjustment mechanism 1 includes a drive platform 101, with an inspection cover 102 movably engaged at the top of the drive platform 101. A screw 103 is rotatably connected to the inner side of the drive platform 101 via a built-in motor. A nut seat 104 is threadedly connected to the surface of the screw 103, and a hinge rod 105 is rotatably connected to the top of the nut seat 104.

[0023] By setting up an angle adjustment mechanism 1, the built-in motor uses a screw 103 to drive the nut seat 104 to rotate the hinge rod 105, so that the top of the hinge rod 105 drives the cable clamping structure 2 to adjust the angle, thereby adjusting the bending angle of the corresponding cable during the installation process. This avoids damage to the cable caused by excessive bending angle during the installation process, ensuring that the cable can avoid obstacles during the installation process and reducing the occurrence of cable damage, thus effectively protecting the cable.

[0024] The cable clamping structure 2 includes a cable pass-through box 201 and a protective cover 202. The bottom end of the cable pass-through box 201 is hinged to the end of the hinge rod 105 away from the nut seat 104. The cable pass-through box 201 has a pass-through port on both the front and back sides. A fixing device 204 is fixedly installed inside the cable pass-through box 201.

[0025] The fixing device 204 includes a vertical plate 205, a vertical groove 206 is provided on the front side of the vertical plate 205, a rotating arm 207 is slidably connected inside the vertical groove 206, two clamping claws 208 are hinged to the top of the rotating arm 207, and an electric hydraulic push rod 211 is fixedly installed on the top of the vertical plate 205. The movable end of the electric hydraulic push rod 211 is fixedly connected to the clamping claw 208 on the left side.

[0026] By setting up the cable clamping structure 2, multiple sets of fixing devices 204 inside the cable conduit box 201 can assist in clamping the cable, so that the structure can be adapted to fix the cable according to the diameter, thereby improving the versatility of the structure and enabling the protection structure to be used for cable protection of different sizes.

[0027] Specifically, the inspection cover 102 has a through-hole inside, and the hinge rod 105 extends through the through-hole to the top of the inspection cover 102. In this embodiment, the inspection cover 102 facilitates the inspection of the inside of the angle adjustment mechanism 1, while the through-hole limits the hinge rod 105 to prevent positional displacement of the hinge rod 105 during rotation.

[0028] Specifically, a toothed ring 106 is fixedly sleeved on the surface of the screw 103, and a rack 107 is movably connected to the inner wall of the drive platform 101 via an electric telescopic rod. The rack 107 and the toothed ring 106 mesh with each other. In this embodiment, the rack 107 is moved by the electric telescopic rod, causing the rack 107 and the toothed ring 106 to mesh with each other, thereby locking the screw 103. This allows the screw 103 to be fixed by the rack 107 and the toothed ring 106 after the bending angle of the cable is adjusted, preventing the screw 103 from rotating without external force, thus improving the stability of the electrical engineering cable protection structure.

[0029] Furthermore, the rack 107 and the toothed ring 106 allow operators to easily adjust the cable bending angle by controlling the electric telescopic rod to move the rack 107, causing it to separate from the toothed ring 106 and thus releasing the lock on the screw 103. At this point, the built-in motor can drive the screw 103 to rotate, thereby enabling further adjustment of the cable bending angle. The operation is simple and convenient, improving the practicality of this electrical engineering cable protection structure.

[0030] Specifically, a hinge seat 203 is fixedly connected to the bottom end of the cable conduit 201, and the cable conduit 201 is rotatably connected to the notch of the drive platform 101 through the hinge seat 203. In this embodiment, the hinge seat 203 allows the cable conduit 201 to rotate at the notch of the drive platform 101, thereby cooperating with the angle adjustment mechanism 1 to adjust the angle of the cable.

[0031] Specifically, a slider 209 is installed at the bottom end of the gripper 208, and the slider 209 is slidably connected to a groove opened at the top end of the vertical plate 205. In this embodiment, the movement trajectory of the gripper 208 is limited by the slider 209 and the groove, making the gripper 208 more stable when moving.

[0032] Specifically, a contact pad 210, which is a sponge pad, is provided on the inner side of the clamping claw 208. In this embodiment, the contact pad 210 increases the friction between the clamping claw 208 and the cable, thereby improving the clamping effect of the clamping claw 208 on the cable. At the same time, the sponge pad prevents the clamping claw 208 from damaging the cable.

[0033] When using the cable protection structure of this utility model, the operator first passes the cable through the cable pass-through opening of the cable pass-through box 201, and then activates the electric hydraulic push rod 211. The movable end of the electric hydraulic push rod 211 pushes the left clamping claw 208 to move to the right. Since the two clamping claws 208 are hinged to the top of the rotating arm 207, the bottom end of the rotating arm 207 begins to slide down along the vertical groove 206, causing the top end of the rotating arm 207 to gradually close. Therefore, the right clamping claw 208 will move to the left, and the two clamping claws 208 gradually approach and clamp the cable.

[0034] The slider 209 at the bottom of the gripper 208 slides within the groove at the top of the vertical plate 205, ensuring the stability of the gripper 208's movement. The contact pad 210 not only increases the friction between the gripper 208 and the cable, improving the gripping effect, but its sponge pad material also prevents the gripper 208 from damaging the cable.

[0035] When it is necessary to adjust the bending angle of the cable, the operator can control the built-in motor to drive the screw 103 to rotate. The screw 103 drives the nut seat 104 to move, causing the nut seat 104 to drive the hinge rod 105 to deflect at an angle. This allows the nut seat 104 to drive the cable clamping structure 2 to adjust the angle through the hinge rod 105, thereby achieving the adjustment of the bending angle of the cable.

[0036] After adjustment, the staff can use the electric telescopic rod to push the rack 107 to move, so that the rack 107 and the toothed ring 106 mesh with each other, locking the screw 103 and ensuring the stability of the cable bending angle.

[0037] It should be noted that the specific models and specifications of the built-in motor, electric hydraulic push rod 211, and electric telescopic rod in the cable protection structure of this utility model need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] Furthermore, the power supply and working principle of the built-in motor, electric hydraulic push rod 211, and electric telescopic rod in the cable protection structure of this utility model are clear to those skilled in the art, and will not be described in detail here.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
