Description

Technical Field

[0001] The utility model relates to the field of prefabrication of overhead contact wires for rail transit, and particularly to an overall overhead contact wire prefabrication device for catenary. Background Art

[0002] In the urban rail transit system, the overhead contact wires hanging on the catenary are a crucial component, which is responsible for regulating the height of the catenary to ensure the stable and safe operation of the train. In the traditional production process of overhead contact wires, manual measurement and crimping are mainly relied on.

[0003] However, this traditional method has obvious limitations. First, since the overhead contact wire material is mostly soft copper stranded wire, which is soft in texture, it is difficult to ensure the complete straightening of the wire during manual measurement, resulting in large errors in the measurement results. Second, during the manual crimping process, due to the matching accuracy of components and the instability during the crimping process, the finished product size often deviates.

[0004] In addition, the efficiency of manually making overhead contact wires is relatively low, and the average production time for a single overhead contact wire reaches 7 - 8 minutes. In the daily maintenance and special construction of urban rail transit, the demand for overhead contact wires is usually large, and this inefficient production method is difficult to meet the needs of rapid construction. More seriously, once a deviation occurs in the production of overhead contact wires, due to the crimping method, it is very difficult to adjust this deviation, resulting in a large amount of material waste.

[0005] Therefore, in view of the above problems, it is necessary to develop a new overhead contact wire production technology to improve production accuracy, efficiency and flexibility, reduce material waste, and meet the growing needs of the urban rail transit system. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0061] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0062] The utility model provides a prefabrication device for an integral catenary suspension string, which comprises a workbench T, on which a master control component, a pretreatment component, a positioning component and a fastening component are arranged. The master control component is respectively connected with the pretreatment component and the fastening component, and the master control component outputs signals to the pretreatment component and the fastening component. The pretreatment component responds to the signals output by the master control component, pushes the copper wire forward to the preset length of the suspension string and automatically cuts it. The positioning component is used to position the positions of the copper sleeves and the heart-shaped rings and the path of the copper wire. There are two copper sleeves, which are respectively sleeved at both ends of the copper wire, and there are two heart-shaped rings, which are respectively arranged at the preset positions of the copper wire. The fastening component responds to the signals output by the touch-type master control component, crimps the copper sleeves and the heart-shaped rings with the copper wire, and tightens the copper wire.

[0063] Further, the signals output by the master control component include an outgoing line signal and a cutting signal, and the pretreatment component includes a length automatic control mechanism 1 and an automatic cutting mechanism 2. As Figure 1 shown, the length automatic control mechanism 1 is arranged on the workbench T. The length automatic control mechanism 1 responds to the outgoing line signal output by the master control component and pushes the copper wire forward to the preset outgoing line length. The length automatic control mechanism 1 detects the length of the suspension string in real time, controls the prefabrication device for the integral catenary suspension string to accurately control each action mechanism according to the preset outgoing line length, and ensures that the length of the copper wire for making the suspension string meets the requirements. The automatic cutting mechanism 2 is arranged in front of the length automatic control mechanism 1. The automatic cutting mechanism 2 responds to the cutting signal output by the master control component and cuts the copper wire that has advanced to the preset outgoing line length. Among them, the forward direction of the copper wire is the front.

[0064] Furthermore, the length automatic control mechanism 1 includes a driven wheel, a first motor and a driving wheel. The driven wheel is arranged on the workbench T. The driven wheel supports and guides the copper wire, and the driven wheel moves synchronously with the copper wire. The first motor is arranged on the workbench T. The first motor responds to the outgoing line signal output by the master control component. The driving wheel is connected with the first motor. The driving wheel is driven by the first motor, and then the driving wheel drives the copper wire to advance. The driving wheel controls the moving distance of the copper wire according to the preset outgoing line length value. If the length of the copper wire does not reach the preset value, the master control component will send an instruction to the driving wheel to make it continue to rotate to push the copper wire forward. Once the length of the copper wire reaches or exceeds the preset value, the master control component will stop outputting signals to the first motor, and then stop the rotation of the driving wheel, so as to realize the accurate control of the length of the suspension string. In this embodiment, the general suspension string lengths (500mm - 1400mm) on the line all meet the prefabrication conditions.

[0065] Furthermore, the automatic cutting mechanism 2 includes a cutting head mechanism 21, a guide block 22 and a pressing mechanism 23. As Figure 1 shown, the cutting head mechanism 21 is arranged in front of the length automatic control mechanism 1.

As Figure 2As shown, in one embodiment, the guiding block 22 is arranged at Figure 1 position B of the middle workbench T. Specifically, the guiding block 22 is arranged in front of the cutting head mechanism 21, and the guiding block 22 is used to define the advancing path of the copper wire. The pressing mechanism 23 is arranged behind the cutting head mechanism 21, and the pressing mechanism 23 is used to fix the copper wire. Herein, the direction opposite to the advancing direction of the copper wire is the rear.

[0066] Furthermore, the cutting head mechanism 21 includes a second motor, a lead screw, and a cutting head, see Figure 4 . The second motor is arranged on the workbench T, and the second motor responds to the cutting signal output by the master control component. The lead screw is connected to the second motor, and the second motor drives the lead screw. The cutting head is connected to the lead screw, and the lead screw pushes the cutting head. Briefly, when it is necessary to cut the copper wire, the second motor drives the lead screw to drive the cutting head to cut the copper wire.

[0067] Further, the signals output by the master control component include a pressing signal and a tightening signal. The fastening component includes: two symmetrically arranged first crimping mechanisms 6, two symmetrically arranged second crimping mechanisms 7, and two symmetrically arranged tightening mechanisms 8, see Figure 3 . The first crimping mechanism 6 and the second crimping mechanism 7 respond to the pressing signal output by the master control component. The two second crimping mechanisms 7 are arranged inside the two first crimping mechanisms 6. The two first crimping mechanisms 6 respectively crimp the copper sleeves sleeved at both ends of the copper wire and the copper wire, and the two second crimping mechanisms 7 respectively crimp the two heart-shaped rings and the copper wire. The two tightening mechanisms 8 are arranged behind the two second crimping mechanisms 7, and the two tightening mechanisms 8 respond to the tightening signal output by the master control component to tighten the copper wire. In one embodiment, the tightening mechanism 8 is connected to the copper wire through a lead screw mechanism inside it. When the motor inside it works, it pushes the lead screw to stretch, so as to realize the tightening operation of the copper wire.

[0068] Furthermore, the first crimping mechanism or the second crimping mechanism includes a hydraulic cylinder 9, a pressing component, and a pneumatic valve 10. The hydraulic cylinder 9 is arranged on the workbench T, and the hydraulic cylinder 9 responds to the pressing signal output by the master control component. The pressing component is connected to the hydraulic cylinder 9. When the hydraulic cylinder 9 works, it presses the heart-shaped ring or the copper sleeve through the pressing component to ensure a firm connection between it and the copper wire. The pressing component includes two symmetrically arranged pressing blocks. The copper wire is located between the two pressing blocks. The two pressing blocks are pushed by the hydraulic cylinder 9 to move synchronously towards the copper wire to crimp the copper sleeve and the copper wire or the heart-shaped ring and the copper wire. The pneumatic valve 10 is connected to the hydraulic cylinder 9, and the pneumatic valve 10 is pressed to release the two pressing blocks.

[0069] Further, the positioning component includes two symmetrically arranged copper sleeve tightening mechanisms 3, two symmetrically arranged copper wire positioning blocks 4, and two symmetrically arranged heart-shaped ring tightening mechanisms 5, see Figure 3 and Figure 5。Two copper sleeve fastening mechanisms 3 are respectively arranged in front of the two first crimping mechanisms 6. Two copper wire positioning blocks 4 are respectively arranged between the two first crimping mechanisms 6 and the two tightening mechanisms 8. Two heart-shaped ring fastening mechanisms 5 are respectively arranged in front of the two tightening mechanisms 8. Among them, taking the extending direction of the two ends of the copper wire as the front, the extending directions of the two ends of the copper wire are the same. The copper sleeve fastening mechanism 3 is connected to the copper sleeve. When crimping the copper wire, the copper sleeve fastening mechanism 3 ensures that the copper sleeve is firmly fixed on the copper wire. The heart-shaped ring fastening device 5 is connected to the heart-shaped ring and is responsible for fixing the position of the heart-shaped ring. The copper wire positioning block 4 is responsible for fixing the position of the copper wire to ensure that the copper wire does not move during the crimping process.

[0070] Further, an enable button 11 is also arranged on the workbench T, and the enable button 11 is connected to the total control component. The total control component is a touch-type total control component, and the touch-type total control component includes a human-machine interaction interface 12. The operator can control and monitor each component through the human-machine interaction interface 12 to realize the automation and precise control of the entire prefabrication process. The human-machine interaction interface 12 includes: a length setting interface, an outgoing wire button, a cutting button, a pressing button, and a tightening button. The signals output by the total control component include an outgoing wire signal, a cutting signal, a pressing signal, and a tightening signal. Among them, the length setting interface is used to set the preset length of the suspension. Press the outgoing wire button and the enable button 11 simultaneously to output an outgoing wire signal to push the copper wire forward to the preset length of the suspension. Press the cutting button and the enable button 11 simultaneously to output a cutting signal to automatically cut the copper wire that has advanced to the preset length of the suspension. Press the pressing button and the enable button 11 simultaneously to output a pressing signal to crimp the copper sleeve, the heart-shaped ring, and the copper wire. Press the tightening button and the enable button 11 simultaneously to output a tightening signal to tighten the copper wire.

[0071] In another embodiment, the total control component can be used to set the preset length of the suspension, but operation buttons such as the outgoing wire button, the cutting button, the pressing button, and the tightening button are separately arranged on the workbench T and are connected to the total control component. See Figure 7 。

[0072] Further, a power supply component is also arranged on the workbench T. The power supply component includes a power supply 13 and a main power switch 14. The main power switch 14 is respectively connected to the power supply 13 and the total control component.

[0073] Further, an emergency stop switch 15 is also arranged on the workbench T and is connected to the total control component. When the emergency stop switch is pressed, the mechanism inside it will quickly cut off the power line so that the current in the circuit cannot continue to be transmitted, thereby immediately stopping the operation of the equipment.

[0074] Furthermore, a leakage protection mechanism 16 is also provided on the workbench T and is connected to the power supply assembly, playing an important protective role in the entire circuit. It can promptly detect and cut off the leakage current, prevent the occurrence of electric shock accidents, and ensure the safety of personnel and equipment.

[0076] First, pass the copper wire through the driven wheel, set the wire outlet value on the total control assembly, and click the wire outlet button. The copper wire is advanced by driving the driving wheel through the first motor below. The position of the copper wire can be viewed through the guide block 22, and then it reaches the specified position. Press down the pressing mechanism 23 in the automatic cutting mechanism 2 to fix it.

[0077] After fixing, press the enable button 11 and the cutting button, and the automatic cutting mechanism 2 starts to work. The second motor drives the lead screw to push the cutting head to complete the cutting. See Figure 4 .

[0078] Put copper sleeves on both ends of the cut copper wire and fix the copper sleeves on the copper sleeve tightening mechanism 3. The copper wire passes through the first crimping mechanism 6, the copper wire positioning block 4, passes through the tightening mechanism 8, then passes through the second crimping mechanism, and a heart-shaped ring is installed at the second crimping mechanism. The heart-shaped ring is fixed by the heart-shaped ring tightening mechanism 5. Then it passes through another tightening mechanism 8, the copper wire positioning block 4 and the first crimping mechanism 6, and another copper sleeve is fixed on another copper sleeve tightening mechanism 3. See Figure 5 .

[0079] After all are fixed, press the enable button 11 and click the pressing button to start the hydraulic cylinders of the first crimping mechanism 6 and the second crimping mechanism 7 to press the copper sleeves and the heart-shaped ring. Subsequently, press the enable button 11 and click the tightening button, and the tightening mechanism 8 starts to work. The motor in the tightening mechanism 8 is powered on to push the lead screw to stretch the suspension string. When it touches the travel switch, the stretching ends. See Figure 6 .

[0080] After the tightening ends, press the pneumatic valve 10, and the copper sleeve tightening mechanism 3 and the heart-shaped ring tightening mechanism 5 are loosened. Press the enable button 11 and the reset button, and the tightening mechanism 8 is reset, then the copper wire can be taken off, and the prefabrication of the entire suspension string is completed.
