Description

Technical Field

[0001] The invention relates to the field of overhead wire hanging string processing, and in particular to a hanging string fixed-length feeding method. Background Art

[0002] With the rapid development of my country's high-speed rail technology, it has put forward newer and higher requirements for the quality and standards of railway technology. In the electrified railway line, the contact network is an important part to ensure the normal operation of the railway. The contact network is connected to the electrified railway power supply line to provide power to the electric locomotive and its ancillary equipment. In the contact network system, the suspension string is one of the key factors for the good contact between the contact network and the locomotive pantograph. On the line, a set of integral suspension strings needs to be installed every 6 to 8 meters to suspend the contact wire on the load-bearing cable, so as to ensure the hanging height of the contact wire and keep the contact wire elastic to ensure that the contact network and the pantograph have a good contact relationship. The suspension string includes a suspension string, a heart-shaped ring and a clamping tube arranged on one side or both sides of the suspension string, and a wire nose arranged at one end or both ends of the suspension string. The production process of suspension strings is mainly divided into several steps, including wire cutting, threading, tensioning, crimping, marking and bundling. Threading includes passing the suspension string through the clamping tube, heart-shaped ring and wire nose. Tightening refers to tightening the heart-shaped ring and clamping tube with the suspension string. Crimping includes the clamping tube and wire nose and the suspension string. At present, the production method of suspension strings is still mainly manual, and generally four to five people are used as a shift to carry out the processes of the above steps. This production method has problems such as high labor cost and low precision of the finished suspension string products, especially in the two links of wire cutting and crimping of the suspension string. The manual production method has problems such as inconsistent and uneven length, weak crimping or excessive crimping force leading to cracking of the clamping tube and / or wire nose. In the process of wire feeding, since the suspension string is wound on the wire drum, it is necessary to manually release the wire and stretch it for correction, which is time-consuming and labor-intensive, and it is impossible to ensure that the suspension string is in a tensioned state, so it needs to be tensioned in the subsequent production process. In the wire cutting process, the wire cutting method is mainly shearing, that is, manually using tools such as steel pliers to cut the suspension string. The manual shearing wire cutting method has low operating efficiency on the one hand, and cannot meet the needs of mechanical automation production on the other hand. More importantly, it will cause the suspension string to be scattered, that is, the suspension string will be scattered at the cutting point, which is not conducive to the subsequent threading operation, especially when the suspension string passes through the clamp tube and / or inserts into the wire nose, the scattered strands at the end of the suspension string will cause great interference.

[0003] In view of this, the present invention intends to provide a method for feeding suspension strings at a fixed length, utilizing multiple module units to realize automatic wire feeding, correction and tensioning of the suspension strings, utilizing heating, twisting and pulling to realize automatic wire cutting and forming a frustum-shaped end of the suspension strings at the cutting point, thereby solving the technical problem of loose strands of the suspension strings at the cutting point in the prior art and facilitating subsequent threading operations. Summary of the invention

[0004] The present invention is intended to provide a method for loading a hanging string at a fixed length to solve the deficiencies in the prior art. The technical problem to be solved by the present invention is achieved through the following technical solutions.

[0005] A method for feeding a suspension string at a fixed length, the improvement of which lies in: in the first step, the suspension string is manually led out from a wire drum on a feeding module and enters a conveying module after being corrected by a correction module; in the second step, the conveying module conveys the suspension string and allows the suspension string to pass through a wire cutting module and enter a wire feeding module; in the third step, the conveying module and the wire feeding module simultaneously convey the suspension string and stop conveying after the suspension string reaches a predetermined wire feeding length; in the fourth step, the wire cutting module heats, twists and breaks the suspension string to complete a fixed-length wire cutting operation; the correction module, the conveying module, the wire cutting module and the wire feeding module are arranged on a workbench in sequence, and the feeding module is arranged on the side of the workbench; in the fifth step, the wire feeding module conveys the cut suspension string to the next workstation, and the second to fourth steps are repeated to complete the next cutting operation.

[0006] In the present invention, the loading module is used for paying out the wire, that is, placing the wire drum of the suspension string on the loading module, paying out the wire by using the loading driver and the conveying driver, and tensioning the paid-out suspension string by using the synchronous operation of the loading driver and the conveying driver; the correction module is used for correcting the suspension string. The reason why the suspension string needs to be corrected is that the suspension string is wound on the wire drum, and the suspension string is bent when paying out the wire, and the suspension string required for making the suspension string needs to be as straight and long as possible. The suspension string needs to be as straight and long as possible because although the finished suspension string can be slightly bent, it needs to be cut according to the length of the suspension string when making the suspension string, so the suspension string needs to be basically straight; the conveying module is used for conveying the suspension string at a fixed length, and the wire feeding module calculates the length of the conveyed suspension string according to the number of rotations of the conveying driver, stops conveying when the conveyed suspension string reaches a predetermined length, and the wire cutting module on the suspension string production line cuts the wire; the wire feeding module is used for conveying the suspension string, and conveys the suspension string to the next station of the suspension string production line for production.

[0007] In the present invention, the wire cutting and pressing part is used to press the suspension string to provide a fixed end for twisting and breaking the suspension string; the wire cutting and twisting part is used to press the suspension string and twist and break it; the wire cutting power supply part is used to provide power for heating the suspension string located between the wire cutting and pressing part and the wire cutting and twisting part.

[0008] When the present invention is used, after the suspension string passes through the wire cutting pressing part and the wire cutting twisting part, the wire cutting pressing movable block of the wire cutting pressing part presses the suspension string to fix one end of the suspension string; the wire cutting twisting chuck of the wire cutting twisting part clamps the other end of the suspension string under the drive of the wire cutting twisting clamping cylinder; the wire cutting power supply part, the wire cutting power supply copper plate A, the wire cutting pressing part, the suspension string located between the wire cutting pressing part and the wire cutting twisting part, the wire cutting twisting part and the wire cutting power supply copper plate B form a loop, and the wire cutting power supply part starts to supply power; the cross-sectional area of ​​the suspension string located between the wire cutting pressing part and the wire cutting twisting part in the whole loop is the smallest, according to the principle that the smaller the cross-sectional area of ​​the conductor, the greater the resistance and Joule's law Q=I 2 Rt, the heat generated by the suspension string between the wire cutting pressing part and the wire cutting breaking part is the greatest, so that the suspension string at this location is softened by heat; the wire cutting breaking driver of the wire cutting breaking part drives the wire cutting breaking chuck to rotate to twist the suspension string between the wire cutting pressing part and the wire cutting breaking part. After the twisting is completed, the wire cutting breaking and pulling cylinder fixed on the wire cutting mounting seat pushes the wire cutting breaking part away from the wire cutting pressing part to pull the suspension string apart to complete the wire cutting operation.

[0009] Compared with the prior art, the present invention uses a feeding module and a conveying module to automatically feed and tension the suspension string, uses a correction module to correct the suspension string, and uses a wire feeding module to convey the suspension string to the next station. The present invention can realize automatic feeding, correction and tensioning of the suspension string. The suspension string cut by the present invention forms a frustum-shaped end at the cutting position of the suspension string, which will not cause loose strands and is conducive to subsequent threading operations.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Embodiment 1:

[0026] Reference Figure 1-Figure 13 As shown, a method for loading a hanging string at a fixed length is improved in that:

[0027] In the first step, the suspension wire is manually drawn out from the wire drum on the loading module 10 and enters the conveying module 30 after being calibrated by the calibration module 20;

[0028] In the second step, the conveying module 30 conveys the suspension string and allows the suspension string to pass through the wire cutting module 60 and then enter the wire feeding module 40;

[0029] In the third step, the conveying module 30 and the wire feeding module 40 simultaneously convey the suspension wire and stop conveying after the suspension wire reaches a predetermined wire feeding length;

[0030] In the fourth step, the wire cutting module 60 heats, twists and breaks the suspension wire to complete the fixed-length wire cutting operation;

[0031] The correction module 20, the conveying module 30, the wire cutting module 60 and the wire feeding module 40 are sequentially arranged on the workbench 50, and the loading module 10 is arranged on the side of the workbench 50;

[0032] In the fifth step, the wire feeding module 40 conveys the cut suspension wire to the next workstation, and repeats the second to fourth steps to complete the next cutting operation.

[0033] In this embodiment, the feeding module 10 is used for paying out the wire, that is, placing the wire drum of the suspension string on the feeding module 10, and using the feeding driver 15 and the conveying driver 32 to pay out the wire, and using the synchronous operation of the feeding driver 15 and the conveying driver 32 to tension the paid-out suspension string; the correction module 20 is used to correct the suspension string. The reason why the suspension string needs to be corrected is that the suspension string is wound on the wire drum, and the suspension string is bent when paying out the wire, and the suspension string required for making the suspension string needs to be as straight and long as possible. The reason why it is long is that although the finished suspension string can be slightly curved, the string needs to be cut according to its length when it is made, so the string needs to be basically straight; the conveying module 30 is used to convey the suspension string at a fixed length, and the conveying module 30 calculates the length of the conveyed suspension string according to the number of rotations of the conveying driver 32. When the conveyed suspension string reaches a predetermined length, the conveying is stopped, and the wire cutting module on the suspension string production line performs the wire cutting; the wire feeding module 40 is used to convey the suspension string and convey the suspension string to the next station of the suspension string production line for production.

[0034] In this embodiment, the feeding module 10 and the conveying module 30 are used to automatically feed and tension the suspension string, the correction module 20 is used to correct the suspension string, and the wire feeding module 40 is used to convey the suspension string to the next workstation. Compared with the prior art, this embodiment can realize automatic feeding, correction and tensioning of the suspension string.

[0035] Furthermore, by calculating the difference between the number of revolutions of the conveying driving wheel 34 of the conveying module 30 and the distance between the conveying module 30 and the wire cutting module 60, it is determined whether the hanging string in the third step reaches the predetermined length of wire delivery.

[0036] Further, the fourth step is specifically as follows: ① the wire pressing movable block 613 on the wire pressing part 61 in the wire cutting module 60 presses the suspension string; ② the wire cutting and breaking chuck 623 on the wire cutting and breaking part 62 in the wire cutting module 60 is pulled by the wire cutting and breaking clamping cylinder 6221 to clamp the suspension string passing through the wire cutting and breaking chuck 623; ③ the wire cutting power supply part 64, the wire cutting power supply copper plate A641, the wire pressing part 61, the suspension string located between the wire pressing part 61 and the wire cutting and breaking part 62, the wire cutting and breaking part 62 and the wire cutting module 60; The wire power supply copper plate B642 forms a circuit, the wire cutting power supply part 64 supplies power, and the suspension string located between the wire cutting pressing part 61 and the wire cutting twisting part 62 heats up and softens; ④ the wire cutting twisting driver 6211 of the wire cutting twisting part 62 drives the wire cutting twisting chuck 623 to rotate to twist the suspension string located between the wire cutting pressing part 61 and the wire cutting twisting part 62; ⑤ the wire cutting twisting and breaking cylinder 629 fixed on the wire cutting mounting seat 63 of the wire cutting module 60 pushes the wire cutting twisting part 62 away from the wire cutting pressing part 61 to break the suspension string and complete the cutting operation.

[0037] In this embodiment, the wire cutting and pressing part 61 is used to press the suspension string to provide a fixed end for twisting and breaking the suspension string; the wire cutting and twisting part 62 is used to press the suspension string and twist and break it; the wire cutting power supply part 64 is used to provide power for heating the suspension string located between the wire cutting and pressing part 61 and the wire cutting and twisting part 62.

[0038] When the present embodiment is used, after the suspension string passes through the wire cutting pressing part 61 and the wire cutting breaking part 62, the wire cutting pressing movable block 613 of the wire cutting pressing part 61 presses the suspension string to fix one end thereof; the wire cutting breaking chuck 623 of the wire cutting breaking part 62 clamps the other end of the suspension string under the drive of the wire cutting breaking clamping cylinder 6221; the wire cutting power supply part 64, the wire cutting power supply copper plate A641, the wire cutting pressing part 61, the suspension string located between the wire cutting pressing part 61 and the wire cutting breaking part 62, the wire cutting breaking part 62 and the wire cutting power supply copper plate B642 form a circuit, and the wire cutting power supply part 64 starts to supply power; the cross-sectional area of ​​the suspension string located between the wire cutting pressing part 61 and the wire cutting breaking part 62 in the entire circuit is the smallest, and according to the principle that the smaller the cross-sectional area of ​​the conductor, the greater the resistance and Joule's law Q=I 2 Rt, the heat generated by the suspension string between the wire cutting pressing part 61 and the wire cutting breaking part 62 is the greatest, so that the suspension string at this location is softened by heat; the wire cutting breaking driver 6211 of the wire cutting breaking part 62 drives the wire cutting breaking chuck 623 to rotate to twist the suspension string between the wire cutting pressing part 61 and the wire cutting breaking part 62. After the twisting is completed, the wire cutting breaking and pulling cylinder 629 fixed on the wire cutting mounting seat 63 pushes the wire cutting breaking part 62 away from the wire cutting pressing part 61 to pull the suspension string apart to complete the wire cutting operation.

[0039] During specific use of this embodiment, the wire cutting module 60 is installed on the workbench 50 and is located between the conveying module 30 and the wire feeding module 40. The wire drum of the suspension string is unloaded by the loading module 10, the correction module 20 corrects the suspension string, and the conveying module 30 conveys the suspension string. After the suspension string conveyed by the conveying module 30 reaches a predetermined length, this embodiment performs a wire cutting operation of twisting and fusing. After the wire cutting operation is completed, the wire feeding module 40 conveys the cut suspension string to the next workstation for subsequent operations.

[0040] When the suspension string is cut by the present embodiment, a frustum-shaped end is formed at the cutting position of the suspension string, so that the string will not be scattered and the subsequent threading operation is facilitated.

[0041] Embodiment 2:

[0042] Based on Example 1, Figure 1As shown, the loading module 10 includes a loading support base plate 11, a loading support side plate A121 and a loading support side plate B122 arranged at both ends of the loading support base plate 11, a loading rotation shaft A161 and a loading rotation shaft B162 respectively arranged at the upper ends of the loading support side plate A121 and the loading support side plate B122 and arranged correspondingly, and the wire drum of the suspension string is clamped between the loading rotation shaft A161 and the loading rotation shaft B162.

[0043] Furthermore, a loading mounting plate A131 is provided on the surface of the loading support side plate A121 facing away from the loading support side plate B122, and a loading reducer 14 is installed on the loading mounting plate A131. The output shaft of the loading reducer 14 is connected to the loading shaft A161, and the loading reducer 14 is connected to the loading drive 15.

[0044] Furthermore, a loading mounting plate B132 is provided on the surface of the loading support side plate B122 facing away from the loading support side plate A121, and a loading chuck 17 for clamping a transverse rod of the loading shaft B162 is provided on the loading mounting plate 132, and the transverse rod is used to adjust the lateral distance of the loading shaft B162 relative to the loading shaft A161.

[0045] Furthermore, a loading chuck wrench 171 is screwed onto the loading chuck 17, and the loading chuck wrench 171 is rotated to allow the loading chuck 17 to clamp or loosen the transverse rod of the loading shaft B162, thereby fixing or adjusting the lateral distance of the loading shaft B162 relative to the loading shaft A161.

[0046] Furthermore, a loading hand wheel 18 is provided at the end of the transverse rod of the loading shaft B162, and the transverse rod is pushed by the loading hand wheel 18 to move laterally to adjust the transverse distance of the loading shaft B162 relative to the loading shaft A161.

[0047] Furthermore, a loading handwheel handle 181 is rotatably provided on the loading handwheel 18 , and the loading handwheel handle 181 can be pulled out and pulled in relative to the loading handwheel 18 .

[0048] Furthermore, a loading shaft A clamping plate 1611 is provided at the end of the loading shaft A161, and the loading shaft A clamping plate 1611 is used to clamp the wire drum of the hanging string.

[0049] Furthermore, a feeding shaft B protrusion 1621 is provided at the end of the feeding shaft B162, and the feeding shaft B protrusion 1621 is used to clamp the wire drum of the suspension string.

[0050] This embodiment provides a preferred implementation of the loading module 10, wherein the loading support base plate 11 is used to support the entire loading module 10, and can be placed at a suitable position on the side of the workbench 50 when in use; the loading support side plate A121 and the loading support side plate B122 are used to support the wire drum of the suspension string and other components in the loading module 10, and the loading reducer 14 and the loading driver 15 are used to provide power for the wire drum of the suspension string to unwind.

[0051] It is worth noting that the wire is released by the feeding driver 15 and the feeding reducer 14, rather than only by the conveying driver 32 of the rear conveying module 30. On the one hand, the load and power of the conveying driver 32 itself can be reduced to avoid excessive load on the conveying driver 32 due to the friction during the wire release process. At the same time, the required rated power of the conveying driver 32 is also reduced, so that a conveying driver 32 with a lower rated power can be selected. On the other hand, the feeding driver 15 and the feeding reducer 14 cooperate with the conveying driver 32 to achieve continuous and stable loading of the hanging string, that is, the feeding driver 15 and the feeding reducer 14 are used to release the wire. The "releasing" of the loading driver 15 and the "pulling" of the conveying driver 32 during transportation realize the continuous stability of the loading process; more importantly, the loading driver 15 and the loading reducer 14 cooperate with the conveying driver 32 to realize the stretching and tensioning of the suspension string while releasing the string, that is, the stable rotation speed of the loading driver 15 and the loading reducer 14 during the releasing process is utilized to prevent the inertia generated by the pulling of the conveying driver 32 on the wire drum of the suspension string from making the suspension string in a relaxed state, that is, the "backward pulling" of the loading driver 15 and the loading reducer 14 cooperates with the "forward pulling" of the conveying driver 32 to realize the stretching and tensioning while releasing the string, thereby cooperating with the correction module 20 to effectively correct the suspension string.
