The electrical installation lead-in device, by providing a No. 1 traction mechanism assembly and a No. 2 traction mechanism assembly, facilitates the staff to quickly lead the cable according to the length of the cable lead-in, improves the efficiency of the staff in leading the cable, ensures the stability of the cable lead-in, and adopts a synchronous adjustment method to make the cleaning ring contact with the surface of the cable, ensures the neatness of the cable after the lead-in, and improves the effect of the subsequent use of the cable.

[0004] This technical solution uses a motor and a screw rod to adjust the lateral distance between the conveyor rollers, thereby facilitating the adaptation of cables of different sizes. Firstly, it increases the energy consumption of the equipment. Secondly, the two conveyor rollers are combined into one conveyor roller with a smaller gap between them, resulting in a smaller contact area between the thicker cable and the conveyor roller without limiting the up and down directions, which makes it easy for large-sized cables to jump out. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an electrical installation lead device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electrical installation lead device, comprising a base, an adjustment component is arranged on the top of the base, and the adjustment component comprises a swing arm, a first spring is connected to one side of the swing arm, a motor is installed on the top of the swing arm, and a transmission shaft is connected to the output end of the motor, a roller is sleeved on the outside of the transmission shaft, and a slide is fixed on the top of the roller, a anti-rotation frame is connected to the inside of the swing arm, and a second spring is connected between the anti-rotation frame and the swing arm.

[0007] By adopting the above technical solution, the cable is directly inserted into the gap between the two swing arms, and the first spring applies thrust to the swing arm so that the roller always clamps the two sides of the cable, so as to automatically adapt to the width of the cable. At the same time, the four rollers will slide on the transmission shaft and move away from each other due to the pressure of the cable. The grooves on both sides of the transmission shaft and the protrusions on the inner ring of the roller can make the rollers slide on the transmission shaft and rotate with the transmission shaft. If the cable diameter is large, the staff can manually slide the four rollers to move away from each other, so that the four rollers are respectively above and below the two sides of the cable, increasing the contact surface and preventing the cable from falling off. The second spring always applies pressure to the roller to increase the pressure of the contact surface, thereby increasing the friction wheel. At the same time, the anti-rotation frame is used to prevent the second spring from rotating with the roller and causing wear, and the slide plate is used to reduce the friction between the anti-rotation frame and the roller to reduce wear.

[0008] Furthermore, grooves are provided on both sides of the transmission shaft, and a protrusion is provided on the inner ring of the roller, and the roller is slidably connected to the transmission shaft through the groove.

[0009] By adopting the above technical solution, after the motor is started, the output end drives the transmission shaft to rotate, and through the grooves on both sides of the transmission shaft and the protrusions on the inner ring of the roller, the roller can slide on the transmission shaft and rotate with the transmission shaft.

[0010] Furthermore, the anti-rotation frame is slidably connected to the swing arm, and the anti-rotation frame abuts against the slide plate.

[0011] By adopting the above technical solution, the roller rotates and the anti-rotation frame prevents the second spring from being worn due to the rotation of the roller.

[0012] Furthermore, the slide plate is made of Teflon material.

[0013] By adopting the above technical solution, the slide plate reduces the friction between the anti-rotation frame and the roller, thereby reducing wear.

[0014] Furthermore, the rollers, the anti-rotation frames, the second springs and the slide plates are each provided in four numbers, and the four rollers, the anti-rotation frames and the slide plates are symmetrically distributed.

[0015] By adopting the above technical solution, the four rollers will slide on the transmission shaft and move away from each other due to the pressure of the cable. If the diameter of the cable is large, the staff can manually slide the four rollers to move them away from each other, so that the four rollers are respectively above and below the two sides of the cable, increasing the contact surface and preventing the cable from falling off. In conjunction with the second spring, pressure is always applied to the rollers to increase the pressure of the contact surface, thereby increasing the friction wheel.

[0016] Furthermore, there are two of each of the swing arm, the first spring, the motor and the transmission shaft, and the two swing arms are mirror-imaged.

[0017] By adopting the above technical solution, the first spring applies thrust to the swing arm so that the roller always clamps the two sides of the cable to automatically adapt to the width of the cable. After the motor is started, the output end drives the transmission shaft to rotate, and through the grooves on both sides of the transmission shaft and the protrusions on the inner ring of the roller, the roller can slide on the transmission shaft and rotate with the transmission shaft.

[0018] Furthermore, brackets are connected to both sides of the top of the base, universal wheels are connected to both sides of the bottom of the base, and cables are arranged inside the swing arm.

[0019] By adopting the above technical solution, the device can be easily moved through the universal wheels, so that it is convenient to reach the lead-in position to carry out the lead-in work on the cable.

[0020] Furthermore, the swing arm is rotatably connected to the base and the bracket respectively.

[0021] By adopting the above technical solution, the first spring applies a thrust to the swing arm so that the roller always clamps both sides of the cable, so as to automatically adapt to the width of the cable.

[0022] Furthermore, a top frame is connected to the top of the bracket, and a hydraulic cylinder is installed inside the top frame. A cutter is connected to the output end of the hydraulic cylinder, and a knife stop frame is connected to the bottom of the top frame.

[0023] By adopting the above technical solution, after the wiring is completed, the staff switches the hydraulic cylinder once. After the hydraulic cylinder is started, the output end drives the cutter to move downward to cut the cable. After the hydraulic cylinder is turned off, the output end drives the cutter to move upward and retract into the knife stop frame. The cutter is blocked by the knife stop frame to prevent the cutter from being exposed and scratching the staff.

[0024] Furthermore, the cutter is slidably connected to the cutter holder.

[0025] By adopting the above technical solution, after the hydraulic cylinder is closed, the output end drives the cutter to move upward and retract into the cutter stop frame, and the cutter is shielded by the cutter stop frame to prevent the cutter from being exposed and scratching the staff.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model directly inserts the cable into the gap between the two swing arms through the setting of the adjustment component, and applies thrust to the swing arm through the first spring so that the roller always clamps the two sides of the cable, so as to automatically adapt to the width of the cable. At the same time, the four rollers will slide on the transmission shaft and move away from each other under the pressure of the cable, and the grooves on both sides of the transmission shaft and the protrusions on the inner ring of the roller make the rollers able to slide on the transmission shaft and rotate with the transmission shaft. If the diameter of the cable is large, the staff can manually slide the four rollers to move away from each other, so that the four rollers are respectively above and below the two sides of the cable, increasing the contact surface and preventing the cable from falling off, and cooperating with the second spring to always apply pressure to the roller to increase the pressure of the contact surface and thereby increase the friction wheel, and at the same time, the second spring is prevented from rotating with the roller and causing wear, and the friction between the anti-rotation frame and the roller is reduced by the slide plate to reduce wear; it can adapt to cables of different sizes, and the large contact surface is convenient for transportation, and it is not easy to cause the cable to fall off.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] An electrical installation lead device, such as Figure 1-Figure 4 As shown, it includes a base 1, and an adjustment component 9 is arranged on the top of the base 1.

[0037] Specifically, the adjustment component 9 includes a swing arm 901 connected to the top of the base 1, the swing arm 901 is rotatably connected to the base 1 and the bracket 3 respectively, a first spring 902 is connected to one side of the swing arm 901, and a thrust is applied to the swing arm 901 through the first spring 902 so that the roller 904 always clamps the two sides of the cable 4; a motor 903 is installed on the top of the swing arm 901, and a transmission shaft 905 is connected to the output end of the motor 903, and a roller 904 is sleeved on the outside of the transmission shaft 905, grooves are provided on both sides of the transmission shaft 905, and a protrusion is provided on the inner ring of the roller 904, and the roller 904 is slidably connected to the transmission shaft 905 through the groove. After the motor 903 is started, the output end drives the transmission shaft 905 to rotate, and the grooves on both sides of the transmission shaft 905 and the roller 904 are used to adjust the rotation of the roller 904. 04 The protrusion on the inner ring enables the roller 904 to slide on the transmission shaft 905 and rotate with the transmission shaft 905. After the roller 904 rotates, the cable 4 is pushed by friction to start the lead-in work; a slide plate 908 is fixed on the top of the roller 904, and the slide plate 908 is made of Teflon material. The slide plate 908 reduces the friction between the anti-rotation frame 906 and the roller 904 and thus reduces the wear; the swing arm 901 is connected to the inside of the anti-rotation frame 906, and the second spring 907 is connected between the anti-rotation frame 906 and the swing arm 901. The anti-rotation frame 906 is slidably connected to the swing arm 901, and the anti-rotation frame 906 and the slide plate 908 are against each other. The anti-rotation frame 906 prevents the second spring 907 from rotating with the roller 904 and causing wear.

[0038] See also Figure 1-Figure 4 In the above embodiment, brackets 3 are connected to both sides of the top of the base 1, universal wheels 2 are connected to both sides of the bottom of the base 1, and cables 4 are arranged inside the swing arm 901. The universal wheels facilitate movement of the device, thereby facilitating the lead-in work of the cable 4 to the lead-in position.

[0039] See also Figure 1-Figure 4 In the above embodiment, there are four rollers 904, anti-rotation frames 906, second springs 907 and slides 908, and the four rollers 904, anti-rotation frames 906 and slides 908 are symmetrically distributed. There are two swing arms 901, first springs 902, motors 903 and transmission shafts 905, and the two swing arms 901 are mirror-imaged to increase the contact surface and prevent the cable 4 from falling off.

[0040] Embodiment 2:

[0041] On the basis of the above-mentioned embodiment 1, although the adjustment component 9 is provided to adapt to cables 4 of different sizes, and the large contact surface facilitates transportation and is not likely to cause the cable 4 to fall off; however, the cable 4 needs to be manually cut by the staff after the wiring is completed, and some thicker cables 4 are more time-consuming and labor-intensive to cut; now by providing a hydraulic cylinder 6, a cutter 7 and a knife stop frame 8, the cable 4 can be automatically cut.

[0042] See also Figure 1 In the above embodiment, a top frame 5 is connected to the top of the bracket 3, a hydraulic cylinder 6 is installed inside the top frame 5, and a cutter 7 is connected to the output end of the hydraulic cylinder 6. After the hydraulic cylinder 6 is started, the output end drives the cutter 7 to move downward to cut the cable 4; a knife stop frame 8 is connected to the bottom of the top frame 5, and the cutter 7 is slidably connected to the knife stop frame 8. After the hydraulic cylinder 6 is closed, the output end drives the cutter 7 to move upward and retract into the knife stop frame 8, and the cutter 7 is blocked by the knife stop frame 8 to prevent the cutter 7 from being exposed and scratching the staff.

[0043] The implementation principle of the utility model is as follows: first, the staff directly inserts the cable 4 into the gap between the two swing arms 901, and applies a thrust to the swing arm 901 through the first spring 902 so that the roller 904 always clamps the two sides of the cable 4, so as to automatically adapt to the width of the cable 4. At the same time, the four rollers 904 will slide on the transmission shaft 905 and move away from each other under the pressure of the cable 4. If the diameter of the cable 4 is large, the staff can manually slide the four rollers 904 to move away from each other, so that the four rollers 904 are respectively above and below the two sides of the cable 4, increasing the contact surface and preventing the cable 4 from falling off, and cooperating with the second spring 907 to always apply pressure to the roller 904 to increase the pressure of the contact surface, thereby increasing the friction wheel;

[0044] After the preparation, the staff turns on the motor 903. After the motor 903 is started, the output end drives the transmission shaft 905 to rotate. Through the grooves on both sides of the transmission shaft 905 and the protrusions on the inner ring of the roller 904, the roller 904 can slide on the transmission shaft 905 and rotate with the transmission shaft 905, thereby rotating the roller 904. At the same time, the anti-rotation frame 906 is used to prevent the second spring 907 from rotating with the roller 904 and causing wear, and the slide plate 908 is used to reduce the friction between the anti-rotation frame 906 and the roller 904 to reduce wear. After the roller 904 rotates, the friction force pushes the cable 4 to start the lead-in work;

[0045] After the wire is led, the staff switches the hydraulic cylinder 6 on and off. After the hydraulic cylinder 6 is started, the output end drives the cutter 7 to move downward to cut the cable 4. After the hydraulic cylinder 6 is turned off, the output end drives the cutter 7 to move upward and retract into the knife stop frame 8. The cutter 7 is blocked by the knife stop frame 8 to prevent the cutter 7 from being exposed and scratching the staff.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
