Technical Field

[0001] The utility model relates to the technical field of metal electrolytic refining, in particular to a cable threading device for building construction. Background Art

[0002] The electrical lines of a building are all pre-buried in wire conduits, and a tape is placed in the conduit in advance to guide the cable into the conduit later. The tape is generally made of steel wire. After the building pipeline is pre-buried, the cable is pulled through the steel wire for threading. When it is necessary to guide the cable through the steel wire as a tape, one end of the cable is generally tied to one end of the steel wire, and then the steel wire is pulled from the other end to pull the cable into the conduit.

[0003] However, existing cable threading devices for construction are often unable to effectively clean the remaining gravel and debris in the cable threading holes during use, which causes the plastic protective shell on the outer wall of the cable to be easily damaged during the cable insertion process, resulting in unnecessary safety hazards.

DETAILED DESCRIPTION

[0022] In order to make the contents of the present invention easier to understand, the technical solution of the present invention is further described below in conjunction with specific implementation methods and drawings, but the present invention is not limited thereto.

[0023] Embodiment 1

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: a cable threading device for construction, comprising a base 1 and a limit plate 19 fixedly arranged at a cable threading hole, a winding wheel 2 and a bellows 7 are fixedly arranged on the top of the base 1, an air supply pipe 17 is fixedly connected to the air outlet of the bellows 7, an exhaust pipe 18 connected to the air supply pipe 17 is fixedly penetrated on the limit plate 19, a pushing bin 8 is fixedly arranged on the top of the bellows 7, a bundling bin 5 is fixedly arranged between the winding wheel 2 and the pushing bin 8, and the winding wheel 2 is wound with a cable 3, and the free end of the cable 3 passes through the gathering chamber 5, the pushing chamber 8 and the exhaust pipe 18 in sequence to enter the cable threading hole. The gathering chamber 5 straightens the cable 3 sent by the winding wheel 2, and the straightened cable 3 is sent into the pushing chamber 8, so that the cable 3 moves forward continuously. At the same time, the bellows 7 cleans the cable threading hole through the air supply pipe 17, which can prevent the cable 3 from being blocked by gravel, mud, etc. when entering the threading hole, resulting in the cable 3 being unable to be inserted forward.

[0025] As a further preference of this embodiment, a threaded hole 20 is opened on the limit plate 19, and the limit plate 19 is fixed to the cable threading hole by a limit screw 21. At this time, the air outlet of the exhaust pipe 18 is inserted into the cable threading hole.

[0026] Embodiment 2

[0027] Combination Figure 5 A support rod 4 is fixedly provided on the top of the base 1, and a gathering bin 5 is fixedly provided on the top of the support rod 4. A line inlet and a line outlet are respectively provided at both ends of the gathering bin 5. A conveying platform 9 is provided in the gathering bin 5. A fixture 10 is symmetrically provided at the opening of the gathering bin 5. A limiter 12 is movably provided on the inner side of the fixture 10. A screw rod 11 is passed through the fixture 10. One end of the screw rod 11 is rotatably connected to the limiter 12, and the other end of the screw rod 11 passes through the gathering bin 5.

[0028] From the above description, it can be seen that the cable 3 moves from the winding wheel 2 to the gathering chamber 5, enters from the cable inlet of the gathering chamber 5, and adjusts the screw rods 11 on both sides of the gathering chamber 5 to drive the limiters 12 rotatably connected to the inner side of the screw rods 11 to move in the direction of the cable 3 until the limiters 12 on both sides clamp the cable 3. At this time, the cable 3 is pulled again to make the cable 3 pass through the limiters 12, thereby achieving the purpose of straightening the cable 3.

[0029] Embodiment 3

[0030] Electric telescopic rods 22 are symmetrically fixedly arranged in the pushing bin 8, and the output ends of the electric telescopic rods 22 are fixedly connected to electric rollers 6. The cable 3 passes through the electric rollers 6 on both sides. By controlling the electric telescopic rods 22, the electric rollers 6 on both sides are overlapped with the outer wall of the cable 3. Through the cooperation of multiple groups of electric rollers 6, the cable 3 is pushed forward.

[0031] Embodiment 4

[0032] Please refer to Figure 3 and Figure 4 A filter screen 13 is fixedly arranged at one end of the bellows 7, and the filter screen 13 can remove dust, particulate matter and other pollutants in the air. An electric fan 14 is fixedly arranged on one side of the bellows 7 near the filter screen 13, and the electric fan 14 is fixedly connected to a main shaft 15, and the other end of the main shaft 15 is fixedly connected to a wind tube 16.

[0033] Combination Figure 6 The exhaust pipe 18 is provided with an annular cavity, and a plurality of ventilation holes are opened in an annular array on one side of the exhaust pipe 18 close to the cable threading hole, and the air supply pipe 17 is connected to the annular cavity of the exhaust pipe 18.

[0034] As can be seen from the above description, the electric fan 14 in the bellows 7 is started, and air is sucked into the bellows 7 by the electric fan 14, and the air flow is blown into the wind tube 16 by the electric fan 14, and the wind tube 16 is rotated, so as to achieve the effect of compressing the air flow in the bellows 7, so that the air is discharged into the exhaust pipe 18 through the air supply pipe 17 set at one end of the wind tube 16, and finally enters the threading hole from the ventilation hole on one side of the exhaust pipe 18, and the gravel and debris remaining in the threading hole is blown out, which further solves the problem that the traditional threading equipment cannot effectively clean the gravel and debris remaining in the threading hole during use, resulting in the plastic protective shell of the cable 3 being damaged during the insertion process of the cable 3, thereby causing unnecessary safety hazards.
