Description

Technical Field

[0001] The present invention relates to the technical field of wire threading, and particularly relates to an auxiliary device for threading wires in electrical pipelines. Background Art

[0002] At present, with the development of science and technology, people have higher and higher requirements for the functions of buildings. Electricity plays an increasingly important role in buildings, and threading wires in electrical engineering pipes in buildings is a crucial link in the electrical system. During building construction, pipelines for strong electricity or weak electricity need to be embedded in the building structure, and after the building construction is completed, wires need to be threaded into the embedded pipelines. Currently, the main method is to manually pull the wires.

[0003] In the existing operation mode, the wire is extremely likely to be repeatedly scratched against the pipe orifice when entering, which easily causes wear of the wire and affects the wire threading quality. Moreover, during the wire threading process, if not careful, the wire is extremely likely to retract, affecting the wire threading efficiency. In addition, in harsh environments, for example, at low temperatures, the insulation skin of the wire becomes brittle and hard, which is not conducive to wire threading at bends, not only affecting the efficiency but also easily damaging the insulation skin. When there is a large amount of dust, impurities are easily adhered to the insulation skin of the wire, which easily causes the wire to get stuck when walking in the pipeline, affecting the wire threading quality and efficiency.

[0033] The beneficial effects of the present invention are as follows:

[0034] 1.

In this way, the starting position of the wire threading of the cable can be restricted, avoiding the problem of wear caused by repeated friction between the cable and the pipe body port during the insertion process. In addition, the two guide wheels can also play the role of clamping the cable. Without external force, the problem of the cable retracting backward can be prevented; when there is an external force, that is, when the cable is inserted into the pipe body by the external force, since the guide wheels are rotatably arranged, the friction between the cable and the guide wheel 19 can also be reduced.

[0035] 2. In the present invention, through the arrangement of the cleaning assembly, the scraping strip moving backward can push the impurities on the cable backward, improving the effect of the impurities breaking away from the limit; when the third arc-shaped plate resets under the support of the second elastic group, the scraping strip will also contact the outer surface of the cable, playing a small role in assisting the cable to enter. Specifically, when the scraping strip moves backward relative to the cable, since there is an external force to insert the cable forward, in this way, the backward movement of the scraping strip can be prevented from having a negative impact on the wire threading of the cable; when the scraping strip resets and moves forward, since the external force still maintains the state of inserting and limiting forward, at this time, the forward movement of the scraping strip can have a positive impact on the wire threading of the cable;

[0036] 3. In the present invention, through the arrangement of the pushing assembly, only the external force for wire threading the cable can drive the cleaning assembly to perform intermittent pulling operations, and can also drive the knocking block to intermittently impact and vibrate the cable. In this way, the efficiency of cable insertion can be effectively improved.

[0056] Please refer to Figure 1-12 , the present invention provides a technical solution:

[0057] An electrical conduit wire threading auxiliary device, comprising a clamping assembly and a positioning assembly axially connected to the outer end of the clamping assembly;

[0058] The clamping assembly includes two symmetrically arranged first arc-shaped plates 11, and a first elastic component 2 is connected between the two first arc-shaped plates 11. The first elastic component 2 causes the area surrounded by the two first arc-shaped plates 11 to have a tendency to contract towards the inner diameter;

[0059] The positioning component includes second arc plates 13 which are symmetrically arranged and respectively correspond to the two first arc plates 11. The second arc plates 13 and the first arc plates 11 are connected by connecting rods 12. The inner wall ends of the two first arc plates 11 are radially connected with connecting seats 18 through third elastic groups 3. Guide wheels 19 are rotatably arranged on the connecting seats 18. The two third elastic groups 3 respectively act on the two connecting seats 18, so that: the two guide wheels 19 have a tendency to approach each other.

[0060] In this embodiment, the clamping component is used to clamp on the pipe body 1, and the positioning component is used to limit and clamp the cable. Specifically, the two first arc plates 11 are clamped and assembled at the port part of the pipe body 1. Driven by the connecting rod 12, the two guide wheels 19 are located in the rear area of the port part of the pipe body 1. The cable needs to pass through the area between the two guide wheels 19 and then be placed into the pipe body 1. Under the action of the first elastic component 2, the two first arc plates 11 can tightly wrap the outer surface of the pipe body 1. Under the action of the third elastic group 3, the two guide wheels 19 can abut against the outer surface of the cable. In this way, the starting position of the wire threading of the cable can be restricted, and the problem of wear caused by repeated friction between the cable and the port of the pipe body 1 during the placement process can be avoided. In addition, the two guide wheels 19 can also play the role of clamping the cable. Without external force, the problem of the cable retracting backward can be prevented; when there is external force, that is, when the cable is placed into the pipe body 1 by external force, since the guide wheels 19 are rotatably arranged, the friction between the cable and the guide wheels 19 can also be reduced.

[0061] To realize the elastic support of the first elastic component 2 for the two first arc plates 11 and the elastic support of the third elastic group 3 for the two guide wheels 19, preferably, the first elastic component 2 includes two first elastic groups, and the two first elastic groups are respectively at the two end parts of the first arc plates 11;

[0062] The first elastic group includes a first sleeve rod 201 and a first sleeve 202 sleeved on the first sleeve rod 201 and capable of sliding up and down relative to the first sleeve rod 201. The first sleeve rod 201 and the first sleeve 202 are respectively connected to the inner ring surfaces of the same end part of the two first arc plates 11;

[0063] The first elastic group further includes a first elastic member 203 sleeved on the first sleeve rod 201 and the first sleeve 202. The upper and lower ends of the first elastic member 203 are respectively connected to the inner ring surfaces of the two first arc plates 11, and the first elastic member 203 makes the two first arc plates 11 have a tendency to approach each other;

[0064] The third elastic group 3 includes a third sleeve rod 301 connected to the connecting seat 18 and a third sleeve 302 connected to the inner ring surface of the second arc plate 13. The third sleeve 302 is sleeved on the third sleeve rod 301 and can slide relative to the third sleeve rod 301;

[0065] The third elastic group 3 further includes a third elastic member 303 sleeved on the first sleeve rod 301 and the third sleeve 302. The two ends of the third elastic member 302 respectively abut against the connecting seat 18 and the second arc-shaped plate 13, such that: the first sleeve rod 301 is located at the limit position where it extends out of the third sleeve 302.

[0066] In this embodiment, the first sleeve rod 201 and the first sleeve 202 can adaptively adjust the distance between the two first arc-shaped plates 11 according to the outer diameter of the pipe body 1 to achieve the effect of clamping the outer surface of the pipe body 1; the first sleeve rod 301 and the third sleeve 302 can adaptively adjust the distance between the two guide wheels 19 according to the outer diameter of the cable to achieve the effect of clamping and positioning the outer surface of the cable.

[0067] Preferably, the outer end of the positioning assembly is axially connected with a cleaning assembly arranged at an interval from the positioning assembly;

[0068] The cleaning assembly includes two symmetrically arranged third arc-shaped plates 14 respectively corresponding to the two second arc-shaped plates 13. A plurality of annularly arranged scraping strips 15 are arranged at the inner wall end of the third arc-shaped plate 14.

[0069] In this embodiment, with the incoming line direction as the front, when the clamping assembly is assembled on the pipe body 1, then the clamping assembly, the positioning assembly, and the cleaning assembly are arranged in sequence from the front to the back. Through the arrangement of the scraping strips 15, larger impurities on the cable can be blocked outside the two guide wheels 19 and the port of the pipe body 1. In this way, not only can the clamping and limiting effect of the two guide wheels 19 on the cable be ensured, but also larger impurities can be prevented from entering the pipe body 1 and causing blockage, thereby avoiding affecting the wire threading efficiency of the cable.

[0070] The scraping strips 15 can be made of silica gel or rubber materials, which can have a certain rigid supporting force and a certain elastic deformation force to prevent damage to the outer surface of the cable.

[0071] Preferably, the second arc-shaped plate 13 and the third arc-shaped plate 14 are connected by a second elastic group 4. The second elastic group 4 acts on the third arc-shaped plate 14, such that: the third arc-shaped plate 14 has a tendency to approach the second arc-shaped plate 13.

[0072] In this embodiment, through the arrangement of the second elastic group 4, the third arc-shaped plate 14 can be pulled backward by an external force. In this way, the backward moving scraping strips 15 can push the impurities on the cable backward, improving the effect of the impurities breaking away from the limit; when the third arc-shaped plate 14 resets under the support of the second elastic group 4, the scraping strips 15 will also contact the outer surface of the cable, playing a small auxiliary incoming line effect.

[0073] It should be noted that when the scraping strip 15 moves backward relative to the cable, since an external force is applied to insert the cable forward, in this way, the negative impact on the wire threading of the cable caused by the backward movement of the scraping strip 15 can be prevented; when the scraping strip 15 resets and moves forward, since the external force still maintains the state of being inserted forward and limited, at this time, the forward movement of the scraping strip 15 can have a positive impact on the wire threading of the cable.

[0074] To achieve the elastic support of the second elastic group 4 for the second arc plate 13 and the third arc plate 14, preferably, the second elastic group 4 includes a second sleeve rod 401 connected to the inner end of the third arc plate 14 and a second sleeve 402 connected to the outer end of the second arc plate 13;

[0075] The second elastic group 4 further includes a second elastic member 403 sleeved on the first sleeve rod 401 and the second sleeve 402. The two ends of the second elastic member 403 are respectively connected to the third arc plate 14 and the second arc plate 13, and the second elastic member 403 makes the third arc plate 14 and the second arc plate 13 have a tendency to approach each other.

[0076] In this embodiment, through the cooperation of the second sleeve rod 401 and the second sleeve 402, not only can the hard support of the second arc plate 14 for the third arc plate 14 be realized, but also the stable movement between the second arc plate 14 and the third arc plate 14 can be realized.

[0077] Preferably, it further includes a pushing component 8 that can act on the third arc plate 14 away from the second arc plate 13;

[0078] The pushing component 8 includes two pushing groups corresponding to the two guiding wheels 19 respectively; each pushing group includes a rotating disk 801 connected to the guiding wheel 19 in a linkage manner, and a plurality of pushing blocks 802 arranged along the circumferential direction are provided at the outer ring end of the rotating disk 801;

[0079] It further includes a cleaning transmission component 10, and the cleaning transmission component 10 includes two cleaning transmission groups respectively cooperating with the two pushing groups;

[0080] Each cleaning transmission group includes a cleaning transmission rod 501 in an "L" shape, a cleaning connection group 6 connected to the horizontal section of the cleaning transmission rod 501, and a cleaning connection block 502 connected to the cleaning connection group 6. The vertical section of the cleaning transmission rod 501 abuts against the outer ring end of the rotating disk 801, and the cleaning connection block 502 is connected to the inner end of the third arc plate 14.

[0081] In this embodiment, through the setting of the pushing component 8, there is no need to separately set an external force to pull the cleaning component, but the external force of the wire threading of the cable can be used to drive the cleaning component to perform intermittent pulling operations in a linkage manner. Specifically, as follows:

[0082] When the cable is inserted forward under the action of external force on the guide wheel 19, the guide wheel 19 will rotate adaptively on the connecting seat 18. During the rotation process, the rotating disc 801 will be driven to rotate. Through the cooperation of the pushing block 802 and the vertical section of the cleaning transmission rod 501, the cleaning transmission rod 501 will be intermittently pushed backward, and then the third arc-shaped plate 14 and the scraping strip 15 will be driven to move backward intermittently, so as to push off larger impurities on the cable. Under the reset action of the second elastic group 4, the third arc-shaped plate 14 and the scraping strip 15 will also move forward intermittently, thus having a positive impact on the cable inlet.

[0083] Preferably, a knocking block 21 is connected to the connecting seat 18 through a knocking elastic group 9. The knocking elastic group 9 acts on the knocking block 21, so that the knocking block 21 has a tendency to move towards the outer diameter end.

[0084] The knocking elastic group 9 includes a support plate 901 connected to the side wall of the connecting seat 18, a fifth sleeve rod 902 connected to the support plate 901, and a fifth sleeve 903 connected to the knocking block 21. The fifth sleeve 903 is sleeved on the fifth sleeve rod 902 and the two can slide relative to each other. The knocking elastic group 9 further includes a fifth elastic member 904 sleeved on the fifth sleeve rod 902 and the fifth sleeve 903. The two ends of the fifth elastic member 904 are respectively connected to the support plate 901 and the knocking block 21, so that the knocking block 21 and the support plate 901 have a tendency to approach each other.

[0085] It further includes a knocking transmission assembly 10 that can act on the knocking block 21 to move towards the inner diameter end. The knocking transmission assembly 10 includes a knocking transmission group corresponding to the cleaning transmission group at the bottom of the two cleaning transmission groups.

[0086] The knocking transmission group includes a knocking linkage rod 1001 connected to the cleaning transmission rod 501 and in an "L" shape, and a knocking push rod 1004 connected to the knocking block 21. The horizontal section of the knocking linkage rod 1001 is connected to the cleaning transmission rod 501. An installation block 1002 is arranged at the inner diameter end of the vertical section of the knocking linkage rod 1001. A transmission protrusion 1003 that can cooperate with the knocking push rod 1004 is connected to the inner diameter end of the installation block 1002.

[0087] In this embodiment, during the process of the rotation of the guide wheel 19 driving the cleaning transmission rod 501 to move back and forth, the knocking linkage rod 1001 will be driven to move back and forth. In this way, the transmission protrusion 1003 can intermittently push up the knocking push rod 1004. The knocking push rod 1004 will then reset and move down under the action of the knocking elastic group 9. Through such repeated up and down movements, the knocking block 21 can form an intermittent impact and vibration effect on the cable. During the impact and vibration process, it helps to loosen the inner cavity of the pipe body 1 and also enables the cable to form self-support. In this way, it is more conducive to the cable inlet operation.

[0088] Among them, the transmission protrusion 1003 can be set in a triangular shape, a frustum shape, etc. that can cooperate with the percussion push rod 1004; through the cooperation of the fifth rod 902 and the fifth sleeve 903, it can rigidly support the up and down movement of the percussion block 21, and can also improve the stability of the up and down movement of the percussion block 21.

[0089] Preferably, it further includes an interlocking limit assembly 7, and the interlocking limit assembly 7 includes two interlocking limit groups corresponding to the two connection seats 18 respectively;

[0090] The interlocking limit group includes a guide rail 701 connected to the connection seat 18 and a slider connected to the cleaning transmission rod 501 and capable of cooperating with the guide rail 701.

[0091] In this embodiment, through the cooperation of the guide rail 701 and the slider 702, the stability of the forward and backward movement of the cleaning linkage rod 501 can be improved, thereby improving the stability of the forward and backward movement of the third arc plate 14 and the scraping strip 15. In addition, the stability of the cooperation between the transmission protrusion 1003 and the percussion push rod 1004 can also be improved.

[0092] Preferably, the cleaning connection group 6 includes a fourth sleeve 601 connected to the outer diameter end of the cleaning transmission rod 501 and a fourth rod 602 connected to the cleaning connection block 502. The fourth sleeve 601 is sleeved on the fourth rod 602 and the two can slide relative to each other.

[0093] In this embodiment, through the arrangement of the fourth rod 602 and the fourth sleeve 601, the radial distance between the cleaning connecting rod 501 and the cleaning connection block 502 can be adjusted adaptively.

[0094] Preferably, an arc-shaped groove 16 is formed on the inner ring surface of the second arc plate 13, and an electric heating plate 17 is installed in the arc-shaped groove 16;

[0095] A temperature sensor 20 is further provided at the inner side end of the second arc plate 13;

[0096] It further includes a control system for controlling the temperature sensor 20 and the electric heating plate 17.

[0097] In this embodiment, the control system can be separately arranged outside the clamping assembly, the positioning assembly and the cleaning assembly. In this way, it can avoid affecting the wire routing of the cable. When encountering a special environment, that is, in a low-temperature environment, the cable entering the line can be heated by the electric heating plate 17, which can soften the brittle and hardened insulating skin, so that it is more conducive to the cable entering operation.
