Description

Technical Field

[0001] The invention relates to a device for pulling wires in a wire trough, in particular to a wire trough pulling device which can be used by remote control means. Background Art

[0002] Cable troughs, also known as wiring ducts or distribution ducts, are primarily used to manage and plan various wiring paths. Industrial plants and computer rooms, in particular, often host many different types of wiring, such as cables, signal lines, and other wiring. Installing these cables on the ground would obstruct workspace and potentially pose a hazard to equipment or personnel. Therefore, cable troughs are typically installed on walls, ceilings, or elevated locations to plan, manage, and protect the various wiring.

[0003] See also Figure 1 As shown, the cable duct 10 has a U-shaped cross section, and a receiving space 12 is formed between the two groove rails 11 to accommodate the wiring, so that the wiring can be laid along the installation direction of the cable duct.

[0004] When laying wiring in the cable duct 10, the construction workers usually need to first lay the lead wires, and then use the lead wires to pull the various wiring. When the wiring is a large cable or special pipeline, it may be necessary to first use the lead wires to pull the thick lead wires, and then use the thick lead wires to pull the wiring to complete the wiring laying operation.

[0005] Cable ducts 10 are often located high up in the environment, forcing construction workers to perform elevated operations, which can be quite dangerous. Furthermore, some cable ducts 10 are not easily accessible for construction workers to pull cables. When multiple cable ducts 10 intersect and intersect at high altitudes, the pulling and routing operations become even more difficult. Sometimes, auxiliary tools are even necessary to complete the pulling and routing operations. If the cable ducts 10 are long, construction workers may need to travel back and forth and repeatedly climb high, or even require multiple people to work simultaneously, to complete the pulling and routing or wiring operations. This increases the time and manpower required for wiring and routing operations, and increases the time and risk of overhead operations. Summary of the Invention

[0006] The main purpose of the present invention is to provide a wire duct puller to improve the safety of wiring operations, and at the same time improve the efficiency and convenience of the operation, thereby reducing the manpower and time costs of wiring operations. In order to achieve the above-mentioned purpose, the wire duct puller of the present invention is mounted on two groove rails on both sides of the wire duct, and comprises: a body, which is mounted on the two groove rails and connected to the two groove rails by a traveling assembly so that the body can be positioned on the wire duct or moved along the wire duct, the traveling assembly includes at least one driving wheel in contact with one of the two groove rails, the body is provided with a remote control drive device and a power supply unit, the power supply unit is electrically connected to the remote control drive device to supply the power required for the operation of the remote control drive device, the driving wheel is driven by the remote control drive device to present a stationary or rotating state, the body is provided with at least one traction part for connecting an external traction line; and a remote control device that transmits an operation signal to a receiving end to operate the remote control drive device.

[0007] In one embodiment, the driving wheel has an anti-slip surface.

[0008] In one embodiment, the traveling assembly includes a driven wheel in contact with the other side groove rail.

[0009] In one embodiment, the driven wheel has a flange for engaging with the top of the groove rail.

[0010] In one embodiment, at least one side derailment prevention component is provided on any inner wall surface of the machine body corresponding to the accommodating space of the two groove rails facing the wire trough.

[0011] In one embodiment, the side derailment prevention assembly includes an anti-derailment wheel for contacting any inner wall surface.

[0012] In one embodiment, the machine body includes a main body, at least one extension body and at least one locking piece. The at least one extension body has at least one plug-in portion inserted into the main body, the at least one plug-in portion is locked by the at least one locking piece, and the width of the machine body is adjusted by the insertion depth of the at least one plug-in portion to adjust the span distance of the machine body according to the spacing between the two groove rails.

[0013] In one embodiment, the wire trough pulling device further includes at least one stopper disposed on a displacement path of the wire trough relative to the machine body to limit the displacement range of the machine body.

[0014] In one embodiment, the power supply unit is a battery.

[0015] In one embodiment, the remote control driving device includes a control unit, a motor, a transmission unit, and a wireless receiving unit.

DETAILED DESCRIPTION

[0024] See also Figures 1 to 3As shown, a wire trough 10 has a rail 11 on each side. The wire trough puller includes a body 20 and a remote control device 30. The body 20 is mounted on the two rails 11 and connected to the two rails 11 by a traveling assembly 21, so that the body 20 can be positioned on the wire trough 10 or moved along the wire trough 10. During implementation, at least one stopper 40 can be provided on the displacement path of the wire trough 10 relative to the body 20 to limit the displacement range of the body 20. For example, a stopper 40 can be provided at the end of the wire trough 10 to prevent the body 20 from falling from the end of the wire trough 10.

[0025] The traveling assembly 21 shown in this embodiment includes two driving wheels 211 and two driven wheels 212, wherein the two driving wheels 211 are in contact with one side of the groove rail 11 (in this embodiment, they are in contact with the top of the groove rail 11), and the two driven wheels 212 are in contact with the other side of the groove rail 11 (in this embodiment, they are in contact with the top of the groove rail 11), so that the body 20 can be stably placed in the cable trough 10 or moved along the installation direction of the cable trough 10; during implementation, the driving wheel 211 has an anti-slip surface (such as a tire skin) to increase the friction between the driving wheel 211 and the groove rail 11, while the driven wheel 212 can adopt a smooth surface to reduce the friction between the groove rail 11.

[0026] The configuration of the traveling assembly 21 in this embodiment is merely illustrative. In actual implementation, the positions and quantities of the driving wheels 211 and the driven wheels 212 may be adjusted and varied to enable the machine body 20 to be positioned or displaced on the cable duct 10 .

[0027] Two anti-lateral slip-off components 22 are respectively provided on each inner wall surface of the housing space 12 of the cable trough 10 corresponding to the two groove rails 11 (a total of four anti-lateral slip-off components 22). The anti-lateral slip-off components 22 include a slip-off prevention wheel 221. The slip-off prevention wheel 221 can be used to contact the inner wall surface to ensure that the body 20 will not slip out of the cable trough 10 laterally, whether it is stationary, moving, or turning along the cable trough 10, thereby improving safety during operation.

[0028] In this embodiment, the two anti-slip wheels 221 located on the same side as the driving wheel 211 normally maintain a non-contact state with the groove rail 11 on the same side, and the two anti-slip wheels 221 (the left one in the figure) have a longer wheelbase. In addition, the two anti-slip wheels 221 located on the same side as the driven wheel 212 normally maintain contact with the groove rail 11 on the same side, and the two anti-slip wheels 221 (the right one in the figure) have a shorter wheelbase. This implementation system provides an indication that when the wire trough 10 has an arc bend, the body 20 can still bend toward the side of the driven wheel 212 (right bend). If it is a reverse bend (left bend), the entire body 20 can be lifted and reversed in the front and back directions and then put back to have the ability to move in the reverse bend (left bend).

[0029] The body 20 is provided with a remote control drive device 23 and a power supply unit 24, which is electrically connected to the remote control drive device 23. During implementation, the power supply unit 24 can be a battery to supply the power required for the operation of the remote control drive device 23. The driving wheel 211 is driven by the remote control drive device 23 to present a stationary or rotating state. Two traction parts 25 in different directions are provided on the body 20 for connection with an external traction line 50. The aforementioned traction line 50 can be a traction wire made of thin steel wire or other materials.

[0030] The remote control device 30 can be operated by a user to release an operation signal (eg, a remote control signal complying with NCC 2.4G specification) for the remote control driving device 23 to receive and operate the remote control driving device 23 .

[0031] See also Figure 2 and Figure 4 As shown, the remote control driving device 23 includes a control unit 231, a motor 232, a transmission unit 233 and a wireless receiving unit 234. The control unit 231 is electrically connected to the power supply unit 24 to obtain power. The control unit 231 is electrically connected to the wireless receiving unit 234 to obtain an operation signal. The control unit 231 is electrically connected to the motor 232 and starts and stops the motor 232 according to the operation signal. The transmission unit 233 is connected to the motor 232 and is driven by the motor 232. When the number of driving wheels 211 is two or more, the transmission unit 233 has an anti-slip differential effect to prevent each driving wheel 211 from idling and driving the body 20 to move.

[0032] See also Figure 2 and Figure 5 As shown, the machine body 20 includes a main body 20a, two extensions 20b, and two locking members 20c. The extensions 20b have an inserting portion 26 that is inserted into the main body 20a. The inserting portion 26 is locked by the locking members 20c, so that the width of the machine body 20 can be adjusted by adjusting the insertion depth of the inserting portion 26. Two driving wheels 211 and two of the anti-slip components 22 are installed on the main body 20a, while two driven wheels 212 and another anti-slip component 22 are installed on the extensions 20b. This allows the span of the machine body 20 to be adjusted according to the spacing between the two groove rails 11, and ensures that the traveling assembly 21 and each anti-slip component 22 can achieve optimal contact with the two groove rails 11 of the cable duct 10.

[0033] See also Figure 3 and Figure 6 As shown, in order to make the walking assembly 21 more firmly connected with the two groove rails 11, the driven wheel 212 has a flange 212a to engage with the top of the groove rail 11, so that the driven wheel 212 is guided by the top of the groove rail 11, so that the body 20 can be stably positioned or displaced on the wire trough 10 through the walking assembly 21.

[0034] As shown in the above figures, the wire trough puller is installed on the wire trough 10 for the traction wire 50 to connect. Its body 20 is straddled on two groove rails 11 through a walking component 21, and the body 20 can be displaced by a remote control device 30, which can reduce the manpower required for the wire pulling operation, making the wire pulling operation more efficient and safer.

[0035] The above description is only illustrative of the present invention and not restrictive. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, and all of them will fall within the scope of protection of the present invention.
