Description

Technical Field

[0001] This invention relates to the field of wiring device technology, and in particular to a low-voltage wiring device and wiring method. Background Technology

[0002] Low-voltage electrical engineering is an important part of building construction. During the construction of low-voltage electrical engineering, wiring is required. In order to improve the safety of wires, some wires need to be run through PP conduits.

[0003] Chinese patent CN217607359U discloses a construction device for low-voltage engineering wiring that can self-clean conduit ropes. The device automatically cleans the dirt on the surface of the conduit rope each time it is wound up and unwound, with timely and effective cleaning without affecting the winding and unwinding of the conduit rope.

[0004] The aforementioned device guides the cable through a conduit rope, allowing it to be threaded into the conduit. However, in actual use, the cable may be piled on the ground, resulting in significant resistance to the conduit rope during the wiring process. Alternatively, the cable may be wound around a roller, but as the cable is unwound layer by layer, the length of cable released in one rotation of the roller gradually decreases, and the speed of the conduit rope is difficult to match the unwinding speed of each layer of cable on the roller. Therefore, the aforementioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a low-voltage wiring device and wiring method to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a low-voltage wiring device and method to solve the problems mentioned in the background art. The existing device guides the cable through the conduit rope so that the cable can be threaded into the conduit. However, in actual use, the cable is either piled on the ground, resulting in large resistance to the conduit rope during the wiring process, or the cable is wound on the roller. As the cable is unwound layer by layer, the length of cable released in one rotation of the roller gradually decreases, and the speed of the conduit rope is difficult to match the unwinding speed of each layer of cable on the roller.

[0007] Based on the above ideas, the present invention provides the following technical solution: a low-voltage wiring installation device, comprising: A spool is used to wind cables. A turntable is disposed on one side of the wire reel, and multiple sets of pressure rods are slidably mounted on the side of the turntable away from the wire reel; The drive belt is located on the side of the turntable away from the wire reel to support the guide rope. When one end of the pressure bar contacts the guide rope and the pressure bar rotates with the turntable, the guide rope can be continuously pushed forward by multiple sets of rotating pressure bars. The limiting post is located on the axis of the turntable and can move along the axis of the turntable. When the two ends of the pressure rod come into contact with the guide rope and the limiting post respectively, the pressure rod can lift the turntable vertically during rotation to change the rotation radius of the end of the pressure rod that is in contact with the guide rope.

[0008] As a further aspect of the present invention: the outer circumferential surface of the limiting post has multiple limiting parts with different diameters. When the limiting post moves relative to the turntable along the turntable axis, the end of the pressure rod away from the guide rope can cooperate with the limiting parts of different diameters.

[0009] As a further aspect of the present invention: multiple sets of rollers are arranged on the inner side of the transmission belt, which can support the upper part of the transmission belt.

[0010] As a further aspect of the present invention: the coil and the turntable are driven to rotate by the same power mechanism.

[0011] As a further aspect of the present invention: a drive unit is arranged along the axial direction of the turntable, and the output end of the drive unit is connected to the limiting post to drive the limiting post to move along the axial direction of the turntable. The drive unit is connected to a distance measuring unit for measuring the winding radius of the cable on the spool. After the outer layer of cable on the spool is completely unwound, the distance measuring unit controls the drive unit to drive the limiting post to move relative to the turntable, so that the end of the pressure rod away from the guide rope abuts against the limiting part with a smaller diameter.

[0012] As a further embodiment of the present invention: a base is provided on the side of the turntable away from the pressure rod and the turntable and the base are rotatably engaged. A boss is fixed on the outer circumference of the base, and a vertical rod fixed on the bottom plate passes through the boss and is elastically engaged with the boss.

[0013] As a further aspect of the present invention: a connecting plate is rotatably mounted on the base plate via a base, and the coil is engaged with the connecting plate.

[0014] As a further aspect of the present invention: the power mechanism includes a motor, and the output shaft of the motor is connected to the connecting plate and the output shaft of the motor is connected to the turntable via a chain or belt drive.

[0015] As a further aspect of the present invention: a groove is provided at the end of the pressure rod away from the limiting post, and a rubber pad is attached to the groove.

[0016] A wiring method using the aforementioned low-voltage wiring device includes the following steps: unwinding the cable by rotating the reel; rotating multiple sets of pressure rods via a turntable, and supporting the guide rope with a transmission belt, so that the pressure rods can move the guide rope during rotation to feed the cable into the conduit; adjusting the rotation radius of the pressure rod near the guide rope end by cooperating with limiting parts of different diameters, so that the walking speed of the guide rope is adapted to the unwinding speed of different layers of cable on the reel.

[0017] Compared with the prior art, the beneficial effects of the present invention are: by setting the limiting post, the rotation radius of the end of the pressure bar that contacts the guide rope can be adjusted, so that the walking speed of the guide rope can match the unwinding speed of different layers of cable, so that the cable is always in a relaxed but not over-unwound state, avoiding the problem of the cable being pulled due to slow unwinding speed or the cable becoming messy due to fast unwinding speed.

[0020] like Figures 1-10 As shown, a low-voltage wiring device includes a reel 2 with a cable wound on it and a drum with a guide rope 9 wound on it. When it is necessary to insert the cable into the pipe, the end of the guide rope 9 can be connected to the cable. By rotating the reel 2 and the drum, the cable and the guide rope 9 can be released. The guide rope 9 gradually pulls the cable into the pipe and finally out of the pipe. The guide rope 9 can be made of steel wire rope and a plastic sleeve is fitted on the outside of the steel wire rope to protect it.

[0021] In actual use, considering the protection of the cable, a power mechanism can be arranged below the reel 2 to drive the reel 2 to rotate, so that the reel 2 can rotate actively and release the cable. In order to drive the guide rope 9 to move, a turntable 5 is arranged on one side of the reel 2. The turntable 5 is equipped with a drive component that cooperates with the guide rope 9, and the turntable 5 is driven to rotate by the aforementioned power mechanism. During the rotation of the turntable 5, the drive component can pull the guide rope 9 forward, thereby driving the cable to pass into the pipe.

[0022] In practical applications, as the cable is gradually unwound from the reel 2, the amount of cable wound on the reel 2 decreases layer by layer, resulting in a gradual decrease in the length of cable released in one rotation of the reel 2. At this time, the speed of the guide rope 9 needs to match the speed of cable release. Based on this, this solution provides a specific embodiment of the drive component to achieve the matching of the speed of the guide rope 9 and the speed of cable unwinding.

[0023] The drive assembly includes multiple sets of pressure rods 11 disposed on one side of the turntable 5. The multiple sets of pressure rods 11 are arranged in a circular array along the axis of the turntable 5, and a limiting post 10 that cooperates with the pressure rods 11 is provided at the center of the turntable 5. Specifically, one end of the pressure rod 11 abuts against the outer circumferential surface of the limiting post 10, while the other end of the pressure rod 11 cooperates with the guide rope 9. Specifically, the end of the pressure rod 11 away from the limiting post 10 is provided with a groove to increase the contact area between the pressure rod 11 and the guide rope 9. A rubber pad is attached to the groove, so that the pressure rod 11 can drive the guide rope 9 to move more stably as the turntable 5 rotates.

[0024] A base 6 is provided on the side of the turntable 5 away from the pressure rod 11, and the turntable 5 and the base 6 are rotatably engaged. The base 6 can move in the vertical direction. Through this structure, when the pressure rod 11 contacts and squeezes the guide rope 9, the turntable 5 can be driven to move in the vertical direction through the cooperation of the pressure rod 11 and the limiting post 10, thereby changing the rotation radius of the end of the pressure rod 11 near the guide rope 9, so as to change the speed at which the guide rope 9 is driven to move, so that the speed at which the guide rope 9 moves can be adapted to the speed at which the reel 2 unwinds the cable.

[0025] Furthermore, combined Figure 3 , Figure 5 as well as Figure 9 As shown, the limiting post 10 has a stepped structure, that is, the outer circumference of the limiting post 10 has multiple limiting parts 1002 with different diameters, and the end of the pressure rod 11 away from the guide rope 9 abuts against the limiting part 1002. By cooperating with the limiting parts 1002 of different diameters, the rotation radius of the end of the pressure rod 11 close to the guide rope 9 can be adjusted.

[0026] To support the unwound guide rope 9, this design includes a drive belt 14 on the side of the turntable 5 near the pressure bar 11. After being released from the drum, the guide rope 9 moves along the upper surface of the drive belt 14. Figure 3 As shown, multiple sets of rollers 21 are arranged on the inner side of the transmission belt 14. The rollers 21 can support the upper part of the transmission belt 14, which is beneficial to support the guide rope 9 at the top of the transmission belt 14, so that one end of the pressure rod 11 can be stably in contact with the guide rope 9.

[0027] In actual use, one end of the guide rope 9 is led out from the drum and fixedly connected to one end of the cable with a clamp or rope. The power mechanism drives the reel 2 and the turntable 5 to rotate. When the turntable 5 rotates, it can actively release the cable, thereby avoiding damage to the cable caused by actively pulling the cable. When the power mechanism drives the turntable 5 to rotate, the turntable 5 can synchronously drive the multiple sets of pressure rods 11 on its outer side to rotate. When the groove on the pressure rod 11 contacts and squeezes the guide rope 9, the pressure rod 11 can drive the guide rope 9 to move forward during its rotation, so that the guide rope 9 can drive the cable to be further inserted into the pipe. Specifically, when the two ends of the pressure rod 11 contact the guide rope 9 and the limiting part 1002 on the limiting post 10 respectively, the transmission belt 14 supports the guide rope 9, so that the pressure rod 11 can lift the turntable 5 and the base 6 upward during the rotation of the turntable 5, so that the end of the pressure rod 11 that contacts the guide rope 9 has a large rotation radius, so that the speed of the guide rope 9 can match the speed of the cable unwinding. As the cable is laid, the outermost layer of cable will be completely unwound, thus reducing the overall diameter of the cable wound on the reel 2. This means the length of cable released per revolution of the reel 2 is reduced. At this point, the drive unit 17 can move the limiting post 10 along the axis of the turntable 5, causing the end of the pressure rod 11 away from the guide rope 9 to abut against the smaller-diameter limiting part 1002 on the limiting post 10. In this situation, as both ends of the pressure rod 11 contact the guide rope 9 and the limiting part 1002 respectively, the height by which the pressure rod 11 lifts the turntable 5 and the base 6 during rotation is reduced, thereby... The radius of rotation of the end of the pressure rod 11 that contacts the guide rope 9 is reduced, thus slowing down the speed at which the pressure rod 11 drives the guide rope 9. This allows the speed at which the cable is released from the inner layer of the coil 2 to match the speed at which the cable is released. In summary, this device, through the setting of the limiting post 10, can adjust the radius of rotation of the end of the pressure rod 11 that contacts the guide rope 9, so that the speed at which the guide rope 9 travels can match the speed at which different layers of cable are unwound. This ensures that the cable is always in a slack but not over-wound state, avoiding the problem of the cable being pulled due to slow unwinding speed or the cable becoming tangled due to fast unwinding speed.

[0028] Combination Figures 5-10 As shown, in order to install the turntable 5, an annular seat 501 is fixedly provided on one side of the turntable 5 near the base 6, and a retaining ring 602 is fixedly provided on the inner circumferential surface of the base 6. The retaining ring 602 is engaged with the recess on the annular seat 501, so that the turntable 5 and the base 6 are rotated and engaged. Figures 1-5 As shown, a boss 601 is fixed on the outer circumference of the base 6, and the upright fixed on the base plate 1 passes through the boss 601 and slides with it. A limit spring 15 is provided between the baffle fixedly sleeved on the outside of the upright and the boss 601. Of course, the limit spring 15 can be sleeved on the outside of the upright. Through this structure, the base 6 and the turntable 5 can be elastically connected to the base plate 1 and can move in the vertical direction.

[0029] To install the coil 2, a connecting plate 16 is rotatably mounted on the base plate 1 via a base. Specifically, the base is fixedly connected to the base plate 1, and the outwardly extending protruding ring on the connecting plate 16 passes through the base and rotatably engages with it. A vertical plate is also fitted on the top of the base plate 1, allowing the sleeve on the axis of the coil 2 to be positioned between the vertical plate and the connecting plate 16. Figure 4 As can be seen, the connecting plate 16 has a socket 1601, and the end face of the coil 2 is fixedly provided with a protrusion 201 that cooperates with the socket 1601. When the coil 2 is rotated and installed between the upright plate and the connecting plate 16, the protrusion 201 is inserted into the socket 1601, so that the connecting plate 16 can drive the coil 2 to rotate synchronously.

[0030] In practical use, the ranging unit 13 can be directly arranged on the outside of the cable reel 2 to measure the diameter of the cable winding. However, for more accurate measurement, a columnar positioning element 3 can be arranged on the outside of the wound cable, and the positioning element 3 is rotatably mounted on the bracket 4. Figures 1-3 As shown, a column 401 is fixedly mounted on the base, and the top of the column 401 extends into the bracket 4 and slides with the bracket 4, allowing the bracket 4 to move along the diameter of the coil 2 on the column 401. A ranging unit 13 is mounted on the base to detect the height of the bracket 4. The ranging unit 13 can be an infrared sensor or an ultrasonic sensor, etc. Figure 5 As shown, the drive unit 17 is fixedly connected to the base 6 via a support plate, and the drive unit 17 can be an electric push rod or similar structure, so that the output end of the drive unit 17 is fixedly connected to the limiting post 10. The aforementioned ranging unit 13 is connected to the drive unit 17 via a controller (microcontroller or PLC). When the outer layer of cable on the coil 2 is completely unwound, the positioning member 3 can move towards the center of the coil 2, thereby making the bracket 4 close to the base. The ranging unit 13 can capture this information and control the drive unit 17 to run through the controller, so that the limiting post 10 moves relative to the turntable 5 along its axial direction.

[0031] Combination Figure 1 As shown, the spool is mounted on the base plate 1 via a support frame. The power mechanism includes a motor mounted on the base plate 1. The output shaft of the motor is connected to the connecting disc 16 and the turntable 5 via a transmission unit 7. The transmission unit 7 can be a belt or a chain, which drives the spool 2 and the turntable 5 to rotate. Since the turntable 5 needs to move in the vertical direction, an adjusting wheel 8 is provided at the transmission unit 7 that cooperates with the turntable 5. The adjusting wheel 8 can move in the horizontal direction, which is conducive to the stable cooperation between the transmission unit 7 and the turntable 5.

[0032] For the installation of the transmission belt 14, side plates 12 are provided on both sides of the transmission belt 14. The rotating shafts at both ends of the transmission belt 14 and the rollers 21 arranged inside the transmission belt 14 are rotatably engaged with the side plates 12. A baffle is fixedly installed on the base plate 1, and the side plates 12 are fixedly installed on the top of the baffle. The adjusting wheel 8 is located inside the baffle. Specifically, in conjunction with... Figure 2 , Figure 7 As shown, a protrusion 801 is installed at the center of the adjusting wheel 8, so that the adjusting wheel 8 and the protrusion 801 are rotatably engaged. The protrusion 801 passes through the strip groove on the baffle and is slidably engaged with it. A crossbar fixedly connected to the baffle by a fixing block passes through the protrusion 801 and is slidably engaged with it. An elastic element 19 is installed between the fixing block and the protrusion 801. The elastic element 19 can be a spring, so that the adjusting wheel 8 is elastically connected to the baffle.

[0033] The pressure rod 11 is slidably engaged with the sliding sleeve fixed to the side of the turntable 5, and the end of the pressure rod 11 near the limiting post 10 extends outward to form a flange, thereby preventing the pressure rod 11 from disengaging from the sliding sleeve. Figure 2 As shown, an arc-shaped guide plate 20 is also fixedly installed on the top of the side plate 12, so that the end of the pressure rod 11 away from the limiting post 10 can cooperate with the inner wall of the guide plate 20 and stably transition to the top of the transmission belt 14.

[0034] Combination Figure 7 As shown, a guide plate 18 is fixedly arranged between the two side plates 12, and the guide rope 9 passes through the guide plate 18 and slides with it. Through this structure, the guide rope 9 unwound from the drum can be stably positioned at the top of the transmission belt 14.

[0035] Combination Figure 10 As shown, in addition to being set in a stepped shape to adapt to the unwinding speed of each layer of cable on the reel 2, the outer circumferential surface of the limiting post 10 can also be set as a conical surface 1001 structure, so that the end of the pressure rod 11 away from the guide rope 9 can transition continuously and stably along the outer circumferential surface of the limiting post 10.

[0036] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
