Description

Technical Field

[0001] The utility model relates to the field of building circuit construction, in particular to a wire threading device for building construction. Background Art

[0002] In the circuit construction process of modern buildings, the steps generally adopted are to first locate according to the design plan, then groove and pre-embed the wire tube, then thread the lead wire, and finally insert the wire through the lead wire to complete the initial stage of wire line layout. However, the existing lead wire threading method generally uses a steel wire that is long enough and has a certain toughness as a lead wire, and then inserts one end of the steel wire into the wire tube, and then continuously squeezes the steel wire into the wire tube until one end of the steel wire passes through the wire tube. However, this method has some disadvantages. First, the end of the steel wire is hard, which is easy to scratch the inner wall of the wire tube, causing damage to the insulation layer; second, the steel wire is sometimes difficult to bend, which affects the threading effect.

[0003] For this purpose, Chinese patent publication number CN209881246U discloses a wire threading device for concealed wire pipes in buildings, comprising a short rod and a round block, the round block is located above the short rod, a spherical groove is concave on the upper surface of the short rod, a support rod is respectively arranged at the left and right ends of the upper surface of the short rod, a circular groove is respectively concave on the left and right sides of the upper surface of the short rod, a support rod is arranged inside the circular groove, and a cylindrical block is fixedly connected to the bottom of the support rod. In the wire threading device for concealed wire pipes in buildings, a plum blossom groove is arranged on the right side surface of the threaded nail, so that it is convenient to use a screwdriver to screw the threaded nail into the interior of the round rod, thereby pushing the arc-shaped pressing plate into the arc-shaped groove, so that the wire can be first inserted into the interior of the round rod, and then the threaded nail cooperates with the pressing plate to press the wire into the arc-shaped groove, and the wire is fixed in the round rod, so that the steel wire is pulled from the other end of the wire pipe, so that the wire passes through the entire wire pipe to complete the threading.

[0004] However, when faced with a wire tube with a long threading distance, the existing wire threading device is often unable to completely penetrate the entire wire tube due to insufficient power. In addition, when the wire tube is bent or has many turns, the existing wire threading device cannot be adjusted according to the internal trajectory of the wire tube and cannot smoothly penetrate these uneven areas in the wire tube. At the same time, the existing wire threading device has no additional rotational power, which makes it impossible for the threading device to quickly and easily drill into the deep of the wire tube, and the threading efficiency of the wires is not high. Utility Model Content

[0005] In view of the above problems, a construction wire threading device is provided. By adding threading components, pushing components and rotating drum structures, the problem that the existing threading device cannot pass through longer wire tubes and cannot smoothly pass through the inner wall of wire tubes with complete or many turns is solved.

[0006] In order to solve the problems of the prior art, the utility model provides a construction wire threading device, comprising a frame, a threading assembly and a propulsion assembly, the threading assembly comprising a threading steel cable, a clamping shaft is fixed to the free end of the threading steel cable, a plurality of steering knuckles are installed at one end of the threading steel cable, the threading steel cable is connected to a threading head through the steering knuckle, and is used to guide the threading steel cable into the wire conduit, and the propulsion assembly comprises two groove wheels, the surfaces of the groove wheels are provided with grooves adapted to the threading steel cable, and the groove wheels are symmetrically installed about the central axis of the threading steel cable, and are used to drive the threading steel cable to run forward or backward.

[0007] Preferably, a clamping shaft is fixed to one end of the steering knuckle, and a clamping slot matched with the clamping shaft is provided at the other end, and the steering knuckle is rotationally connected to the threading steel cable through the clamping shaft and the clamping slot, and the steering knuckle is also rotationally connected to other steering knuckles through the clamping shaft and the clamping slot.

[0008] Preferably, one end of the threading head is set as a hemispherical structure, and the other end is provided with a slot matched with the clamping shaft, and the threading head is rotatably connected with the clamping shaft at one end of the steering knuckle through the slot.

[0009] Preferably, a shaft is fixed to the middle of the groove wheel, the shaft is rotatably connected to the mounting seat, and one end of the shaft is fixedly connected to the output shaft of the servo motor.

[0010] Preferably, a rear end cylinder seat is installed at one end of the upper part of the frame, a wire outlet is installed at the other end of the upper part of the frame, a main rotating motor is installed inside the rear end cylinder seat, a rotating drum is sleeved on one end of the rear end cylinder seat, the rotating drum is fixedly connected to the output shaft of the main rotating motor, a mounting rod is fixed to one end of the rotating drum, and one end of the mounting rod is fixedly connected to the mounting seat.

[0011] Preferably, a winding shaft rod is provided in the middle of the installation rod, and the winding shaft rod is used for winding and threading the steel cable.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a threading steel cable, a clamping shaft, a steering knuckle and a threading head, and the threading head and the threading steel cable are pushed into the wire tube by a pushing assembly, and then the threading wire and the threading head are reversely retracted to bring the wire into the wire tube to complete the threading of the wire. The device can easily pass the wire through a longer pre-buried wire tube, and it will not be unable to penetrate because the wire tube is too long or turns too much.

[0014] 2. The utility model uses a rotational connection between the threading head, the steering knuckle and the threading steel cable. After the threading head is pushed into the wire tube, its direction and angle can be freely adjusted along the direction of the wire tube. At the same time, the hemispherical shape of one end of the threading head also facilitates the operation of the threading head in the wire tube, so that the threading assembly can adapt to pre-buried wire tubes with more complicated laying lines without causing blockage.

[0015] 3. The utility model adds structures such as a main rotating motor, a rotating drum and a mounting rod, so that the threading steel cable can be driven by the rotating drum while being pushed into the wire tube by the pushing assembly, so that the threading steel cable and the threading head can be drilled into the wire tube more easily, and some obstacles in the wire tube can also be easily broken through, thereby improving the success rate of threading.

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 6As shown, a wire threading device for construction includes a frame 1, a threading assembly 3 and a propulsion assembly 2. The threading assembly 3 includes a threading steel cable 31. A clamping shaft 32 is fixed to the free end of the threading steel cable 31. A plurality of steering knuckles 33 are installed at one end of the threading steel cable 31. The threading steel cable 31 is connected to a threading head 34 through the steering knuckle 33, which is used to guide the threading steel cable 31 into the wire conduit. The propulsion assembly 2 includes two groove wheels 23. The surface of the groove wheel 23 is provided with a groove adapted to the threading steel cable 31, and the groove wheel 23 is symmetrically installed about the central axis of the threading steel cable 31, which is used to drive the threading steel cable 31 to run forward or backward.

[0025] The propulsion assembly 2 can continuously push the threading steel cable 31 forward, so that the threading steel cable 31 pushes the threading head 34 deeper into the wire tube. The threading head 34 is provided with a fixing card that can fix the wire. During use, the threading head 34 is first inserted into the wire tube, and the threading steel cable 31 is driven by the groove wheel 23 in the propulsion assembly 2, that is, the threading steel cable 31 is gradually inserted into the wire tube by rotating the groove wheel 23 attached to both sides of the threading steel cable 31, and the threading head 34 is squeezed into the wire tube until the threading head 34 is passed out from the other end of the wire tube, the wire is fixed on the threading head 34, and then the groove wheel 23 is rotated in the opposite direction, so that the threading steel cable 31 pulls back the threading head 34 together with the wire, and the wire is smoothly pulled through the wire tube.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, a clamping shaft 32 is fixed to one end of the steering knuckle 33, and a clamping groove matched with the clamping shaft 32 is provided at the other end. The steering knuckle 33 is rotatably connected to the threading steel cable 31 through the clamping shaft 32 and the clamping groove, and the steering knuckle 33 is also rotatably connected to other steering knuckles 33 through the clamping shaft 32 and the clamping groove.

[0027] The steering knuckle 33 is connected to the threading cable 31 through rotation, and the steering knuckles 33 are connected to each other through rotation. When passing through the curved, turning or uneven area in the wire tube, the connection angle between the clamping shaft 32 and the clamping groove is adjusted to pass through the curved, turning or uneven area in the wire tube, so as to facilitate the threading assembly 3 to smoothly enter and exit the wire tube. The connection between the clamping shaft 32 and the clamping groove in the device can also be replaced by a connection between a spherical groove and a spherical joint, ensuring that the steering knuckle 33 can smoothly pass through the angle change at the connection when encountering a curved angle in the wire tube.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, one end of the guide head 34 is set as a hemispherical structure, and the other end is provided with a slot matched with the clamping shaft 32, and the guide head 34 is rotatably connected with the clamping shaft 32 at one end of the steering knuckle 33 through the slot.

[0029] One end of the threading head 34 is designed as a smooth hemispherical structure, which allows it to enter the wire tube smoothly and squeeze forward without damaging the inside of the wire tube. In addition, the rotational connection between the threading head 34 and the steering knuckle 33 further ensures that the traction head and the steering knuckle 33 can pass through the tortuous or angle-changing areas in the wire tube.

[0030] like Figure 2-Figure 4 As shown, a shaft is fixed in the middle of the groove wheel 23 , the shaft is rotatably connected to the mounting seat 21 , and one end of the shaft is fixedly connected to the output shaft of the servo motor 24 .

[0031] The operation of the servo motor 24 can realize the rapid rotation of the groove wheel 23. The rotation directions of the two groove wheels 23 are always set to rotate in opposite directions, so as to provide driving forces in the same direction on both sides of the traction cable at the same time, driving the traction cable to enter or exit the wire tube. The servo motor 24 is used in automation equipment that needs to have the characteristics of precise positioning, high-speed movement, high torque output, high stability, low noise, etc. The servo motor 24 in the device can provide rotation drive in different directions, and can drive the groove wheel 23 to rotate in different directions according to the use requirements.

[0032] like Figure 1-Figure 3 and Figure 6 As shown, a rear end barrel seat 11 is installed at one end of the upper part of the frame 1, a wire outlet 12 is installed at the other end of the upper part of the frame 1, a main rotating motor 13 is installed inside the rear end barrel seat 11, a rotating drum 14 is sleeved on one end of the rear end barrel seat 11, the rotating drum 14 is fixedly connected to the output shaft of the main rotating motor 13, a mounting rod 15 is fixed to one end of the rotating drum 14, and one end of the mounting rod 15 is fixedly connected to the mounting seat 21.

[0033] The main rotating motor 13 drives the rotating drum 14 to rotate relative to the rear end drum seat 11, and can simultaneously drive the propulsion assembly 2 and the threading assembly 3 to rotate during rotation. This structure can provide rotational power while the propulsion assembly 2 propels the threading steel cable 31 and the threading head 34 into the wire tube, making it easier for the threading head 34 to pass through narrow and tortuous areas in the wire tube, thereby improving the success rate of threading.

[0034] like Figure 1-Figure 3 As shown, a winding shaft rod 16 is provided in the middle of the installation rod 15 , and the winding shaft rod 16 is used for winding and threading the steel cable 31 .

[0035] The winding shaft 16 can be connected to a motor or a manual handle to drive its rotation, so that after the threading of the steel cable 31 is completed, the threading steel cable 31 can be reeled back to the initial position through the winding shaft 16, and the efficiency of the threading head 34 with the wire passing through the wire tube is also improved.

[0036] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
