Description

Technical Field

[0001] This invention relates to the field of mobile machinery and engineering operation technology, and in particular to a mobile threading trolley that integrates bundling, clamping and conveying. Background Technology

[0002] In the production of railway box girders, steel strands need to be threaded through the girder. Traditional methods involve manually threading each strand individually into the ducts of the box girder, often resulting in tangling and low efficiency. To address this, the idea of ​​threading entire bundles instead of individual strands was considered. However, in the process of threading entire bundles, the lack of bundling (binding) of the strands leads to problems such as individual strand warping causing inconvenience during threading, difficulty in controlling the length, and inconsistent end lengths requiring pre-control of end lengths or calculation of the threading length based on the shortest end length. These issues contribute to the low efficiency of threading steel strands. Summary of the Invention

[0003] To facilitate the bundling of steel strands and improve the efficiency of bundling, this invention provides a mobile bundling trolley that integrates bundling, clamping, and conveying.

[0004] This invention provides a mobile threading trolley that integrates bundling, clamping, and conveying, employing the following technical solution: A mobile stranding trolley integrating bundling, clamping, and conveying includes a frame, a tilting frame at one end of the frame, a first clamping mechanism on the tilting frame, a bundling mechanism, a stranding mechanism, and a second clamping mechanism on the frame, the first clamping mechanism, the bundling mechanism, the stranding mechanism, and the second clamping mechanism being arranged along the strand conveying direction.

[0005] In one specific implementation, the flipping frame includes an outer frame and a support rod. The support rod is disposed inside the outer frame, and a lead screw is provided inside the outer frame. The lead screw is threadedly connected to a slider. A first guide rail is provided on the support rod, and the first guide rail extends along the steel strand conveying direction. A first clamping mechanism is disposed on the first guide rail, and the slider is connected to the first clamping mechanism.

[0006] In one specific implementation scheme, the first clamping mechanism includes a first mounting base and a first clamping cylinder. The first clamping cylinder is disposed on the first mounting base, and a first clamping block is provided inside the first mounting base. The piston rod of the first clamping cylinder extends into the first mounting base and is connected to the first clamping block. The first mounting base is disposed on the first guide rail.

[0007] In one specific implementation, the bundling mechanism includes a mounting plate and a rotating ring. The rotating ring is disposed on one side of the mounting plate. The side of the mounting plate facing away from the rotating ring has multiple transmission wheels connected in a driving manner. The side of the mounting plate facing the rotating ring has a connecting wheel, which is coaxially and fixedly connected to the transmission wheels. The rotating ring has a groove, and the connecting wheel is located in the groove, so that the rotation of the connecting wheel drives the rotating ring to rotate. The rotating ring has a binding roller. The mounting plate has a clearance hole communicating with the rotating ring. The mounting plate has a drive motor for driving the transmission wheels.

[0008] In one specific implementation, the threading mechanism includes a second guide rail, a conveyor chain, and a clamping block. The second guide rail is mounted on the frame and has multiple sliding plates. The conveyor chain is mounted on the sliding plates and moves closer or further apart from each other through the sliding plates. The clamping block is mounted on the conveyor chain.

[0009] In one specific implementation, the second clamping mechanism includes a second mounting base and a second clamping cylinder. The second clamping cylinder is disposed on the second mounting base, and a second clamping block is provided inside the second mounting base. The piston rod of the second clamping cylinder extends into the second mounting base and is connected to the second clamping block.

[0010] In one specific implementation, the frame is provided with a third guide rail, the third guide rail is provided with a movable plate, and the second clamping mechanism is disposed on the movable plate.

[0011] In one specific implementation, the movable plate is provided with a slide rail, and the second clamping mechanism slides on the slide rail.

[0012] In one specific implementation, the bottom of the frame is provided with a flatcar, the flatcar is provided with a lifting assembly, and the frame is mounted on the lifting assembly.

[0013] In one specific implementation, the lifting assembly includes a guide frame and a hydraulic cylinder. The guide frame is vertically mounted on the flatcar, and a guide groove is provided on the inner wall of the guide frame. The hydraulic cylinder is mounted on the flatcar, and the frame is mounted on the piston rod of the hydraulic cylinder. Rollers are provided on the side wall of the frame, and the rollers are located in the guide groove.

[0014] In summary, the present invention has the following beneficial effects: 1. The first clamping mechanism feeds the unloaded bundle of steel strands to the braiding mechanism, which then spirals the binding wire around the steel strands to complete the braiding. The threading assembly then threads the steel strands into the holes of the box girder. Finally, the second clamping assembly controls the exposed length of the steel strands, facilitating automatic threading of the steel strands and ensuring threading quality, thus greatly improving the threading efficiency of the steel strands.

[0015] 2. The second clamping assembly can be moved horizontally under the drive of the moving plate, thereby positioning itself at different openings of the box girder. It can transfer multiple openings while moving the entire moving stranding trolley, further improving the efficiency of steel strand stranding. Attached Figure Description

[0021] The following combination Figures 1-4 The present invention will be described in further detail below.

[0022] Reference Figure 1 The mobile skeining trolley integrating skeining, clamping, and conveying includes a flat car 1, specifically an electric front and rear dual steering wheel driven flat car 1, which can turn on the spot and move in all directions, so as to move flexibly in narrow roads and limited spaces, adjust to the optimal working position, move by remote control to avoid the safety hazards caused by following the vehicle; and can be equipped with a large-capacity battery and power warning.

[0023] Reference Figure 1 and Figure 2 The flatcar 1 is equipped with a lifting assembly 4 and a frame 2. The frame 2 is connected to the lifting assembly 4 and can move up and down under the drive of the lifting assembly 4. The frame 2 contains a threading mechanism 7, and a tilting frame 3 is hinged to one end of the frame 2. The tilting frame 3 is equipped with a first clamping mechanism 5. A bundling mechanism 6 is provided between the first clamping mechanism 5 and the threading mechanism 7, which can bundle the entire bundle of steel strands conveyed by the first clamping mechanism 5. Figure 1 (Not shown in the image). The end of the frame 2 away from the flipping frame 3 is provided with a movable plate 14, a slide rail 15 is provided on the movable plate 14, and a second clamping mechanism 8 is provided on the movable plate 14. The second clamping mechanism 8 can slide on the slide rail 15, thereby moving closer to or away from the threading mechanism 7.

[0024] Reference Figure 1 and Figure 2 The first clamping mechanism 5 clamps the steel strands and then conveys them to the bundling mechanism 6. After the bundling mechanism 6 completes the bundling of the entire steel strand, the threading mechanism 7 further conveys the completed steel strands. The second clamping mechanism 8 is initially located on the side close to the threading mechanism 7. After the tail end of the steel strand leaves the threading mechanism 7, the second clamping mechanism 8 clamps the steel strand and moves on the slide rail 15 to continue conveying the steel strand. At the same time, the exposed length of the steel strand is controlled according to requirements. The exposed length of the steel strand refers to the distance between the tail end face and the beam end face after the entire bundle of steel strands is threaded, which must be consistent with the specifications.

[0025] It should be noted that when the steel strand is conveyed into the duct of the box girder by the threading mechanism 7, the steel strand passes through the second clamping mechanism 8, but the second clamping mechanism 8 is in an open state, that is, the second clamping mechanism 8 does not have a clamping effect on the steel strand.

[0026] Reference Figure 1 and Figure 2 The lifting assembly 4 includes a guide frame 41 and a hydraulic cylinder 42. The guide frame 41 is vertically fixed on the flatcar 1, and a vertically extending guide groove 43 is formed on the inner wall of the guide frame 41. The hydraulic cylinder 42 is on the flatcar 1, and the piston rod of the hydraulic cylinder 42 is fixedly connected to the frame 2. Rollers 44 are provided on the side wall of the frame 2, and the rollers 44 are in the guide groove 43. The extension and retraction of the piston rod of the hydraulic cylinder 42 can drive the frame 2 to rise and fall. During the rising and falling of the frame 2, the rollers 44 roll in the guide groove 43, which guides and supports the frame 2 while reducing friction during the rising and falling process.

[0027] Reference Figure 1 and Figure 2A push-pull cylinder 9 is hinged to the inner wall of the frame 2. The piston rod of the push-pull cylinder 9 is hinged to the tilting frame 3, so that the extension and retraction of the piston rod of the push-pull cylinder 9 can drive the tilting frame 3 to rotate relative to the frame 2. When the tilting frame 3 rotates upward, it can reduce the length of the frame 2 in the Y direction, making it easier for the flatcar 1 to drive the frame 2 through narrower gaps.

[0028] Reference Figure 1 and Figure 2 The tilting frame 3 includes an outer frame 31 and support rods 32. The outer frame 31 is connected to a push-pull cylinder 9. Multiple support rods 32 are fixed inside the outer frame 31 to support the first clamping mechanism 5. A lead screw 10 is provided between adjacent support rods 32. The axis of the lead screw 10 is parallel to the direction of the steel strand conveying. A slider 11 is threaded onto the lead screw 10. A first guide rail 12 is fixed on the support rod 32, extending along the direction of the steel strand conveying. The first clamping mechanism 5 is connected to the slider 11 and the first guide rail 12. When the lead screw 10 is rotated, it drives the slider 11 to slide along the direction of the steel strand conveying, causing the slider 11 to drive the first clamping mechanism 5 to retract along the first guide rail 12 along the direction of the steel strand conveying. In some other embodiments, a thrust cylinder can be used instead of the lead screw 10 and slider 11 to push and pull the first clamping mechanism 5.

[0029] Reference Figure 2 The first clamping mechanism 5 includes a first mounting base 51 and a first clamping cylinder 52. The first mounting base 51 is on the first guide rail 12 and is fixedly connected to the slider 11. A first clamping block 53 is provided inside the first mounting base 51. The first clamping cylinder 52 is fixed to the first mounting base 51. The piston rod of the first clamping cylinder 52 extends into the first mounting base 51 and is fixedly connected to the first clamping block 53. The extension and retraction of the piston rod of the first clamping cylinder 52 can drive the first clamping block 53 to rise and fall within the first mounting base 51, so that when the first clamping block 53 descends, it can clamp the steel strand, and when the first clamping block 53 rises, it can release the steel strand. Both the first mounting base 51 and the first clamping block 53 are provided with V-shaped grooves to position the steel strand. After the steel strand enters between the first clamping block 53 and the first mounting seat 51, the piston rod of the first clamping cylinder 52 extends to clamp the steel strand. The lead screw 10 rotates, causing the slider 11 to drive the first mounting seat 51 to move towards the bundling mechanism 6. When the first mounting seat 51 moves to a position close to the bundling mechanism 6, the steel strand enters the threading mechanism 7 and is transported by the threading mechanism 7. The first clamping cylinder 52 releases its grip on the steel strand, and the first mounting seat 51 moves away from the bundling mechanism 6 under the drive of the lead screw 10.

[0030] Reference Figure 3 and Figure 4The bundling mechanism 6 includes a mounting plate 61 and a rotating ring 62. The mounting plate 61 has four drive wheels 63 arranged in a rectangular pattern. In this embodiment, all four drive wheels 63 are synchronous pulleys connected to each other via synchronous belts. In some other embodiments, they may also be sprockets, etc. A drive motor 67 is fixed on the mounting plate 61. The output shaft of the drive motor 67 is connected to any one of the drive wheels 63, enabling the drive motor 67 to drive the drive wheel 63 to rotate.

[0031] Reference Figure 3 and Figure 4 The mounting plate 61, facing away from the drive wheels 63, has connecting wheels 64 that are coaxially and fixedly connected to the four drive wheels 63. The mounting plate 61 has clearance holes for the steel strand to pass through. The rotating ring 62 is located on the side of the mounting plate 61 with the connecting wheels 64. The side wall of the rotating ring 62 has a groove 65 into which the connecting wheels 64 can engage, allowing the four connecting wheels 64 to support and position the rotating ring 62. Since the connecting wheels 64 are coaxially fixed to the drive wheels 63, when the drive wheels 63 rotate, the connecting wheels 64 rotate synchronously, thereby driving the rotating ring 62 to rotate under the action of friction.

[0032] Reference Figure 3 and Figure 4 A binding roller 66 is mounted on the rotating ring 62. The binding roller 66 can rotate relative to the rotating ring 62 and can also rotate around the axis of the rotating ring 62 under the drive of the rotating ring 62. Driven by the transmission wheel 63, the rotating ring 62 rotates, driving the binding roller 66 to rotate, and the binding roller 66 can rotate on its own under the pull of the binding wire. As the steel strand moves towards the bundling mechanism 6 under the drive of the first clamping mechanism 5, the steel strand passes through the middle of the rotating ring 62. The drive motor 67 runs, the rotating ring 62 rotates, and the binding wire on the binding roller 66 is wound around the steel strand. The binding roller 66 rotates as the binding wire is pulled, so as to tightly wind the binding wire around the entire bundle of steel strands according to the preset pitch, and to bundle the steel strands to avoid the problem of warping of individual steel strands.

[0033] Reference Figure 2The bundled steel strands are moved into the threading mechanism 7, which includes a second guide rail 72, a conveyor chain 71, and clamping blocks 73. The second guide rail 72 is on the frame 2 and extends perpendicular to the conveying direction of the steel strands. Two sliding plates 74 are provided on the second guide rail 72. The sliding plates 74 can move closer to each other or further away from each other along the second guide rail 72. The conveyor chain 71 is set on the sliding plates 74, and the clamping blocks 73 are set on the conveyor chain 71. The clamping blocks 73 on the two conveyor chains 71 are arranged opposite each other and are staggered. That is, when the two conveyor chains 71 move closer to each other under the drive of the sliding plates 74, the clamping blocks 73 on the two conveyor chains 71 move closer to each other, clamping the steel strands and further conveying them under the drive of the conveyor chains 71; when the two conveyor chains 71 move further away from each other, they lose the clamping of the steel strands. When clamping the steel strand, the clamping block 73 on one conveyor chain 71 is aligned with the gap between the clamping blocks 73 on the other chain to clamp the steel strand more stably.

[0034] Reference Figure 2 After the end of the steel strand passes through the threading mechanism 7, the second clamping mechanism 8 clamps the steel strand and controls its exposed length. The second clamping mechanism 8 includes a second mounting base 81 and a second clamping cylinder 82. The second mounting base 81 is on the slide rail 15, and a second clamping block 83 is located inside the second mounting base 81. The second clamping cylinder 82 is fixed to the second mounting base 81, and its piston rod extends into the second mounting base 81 and is fixedly connected to the second clamping block 83. The extension and retraction of the piston rod of the second clamping cylinder 82 can drive the second clamping block 83 to rise and fall. After the steel strand enters the second mounting base 81, the second clamping block 83 descends to clamp the steel strand and is further conveyed under the action of the second mounting base 81. V-grooves are also provided on both the second mounting base 81 and the second clamping block 83 to position the steel strand.

[0035] Reference Figure 2 The frame 2 is equipped with a third guide rail 13, which extends perpendicular to the direction of steel strand conveying. The moving plate 14 is set on the third guide rail 13 and can drive the second clamping mechanism 8 to move, so that the second clamping mechanism 8 and the strand threading mechanism 7 can move laterally in the horizontal direction, thereby positioning them in front of different holes in the box girder. Moreover, the moving and positioning of the moving plate 14 is more convenient and more accurate than the moving and positioning of the flat car 1, reducing the moving and positioning process of the flat car 1 and improving the strand threading efficiency.

[0036] The implementation principle of this invention is as follows: The moving threading trolley is positioned at the box girder by the flat car 1. The lifting component 4 controls the height of the frame 2, so that the second clamping mechanism 8 is positioned at the opening of the box girder. After the entire bundle of steel strands is unloaded, the first clamping cylinder 52 pushes the first clamping block 53 to clamp it, and the lead screw 10 and slider 11 transport the steel strands into the bundling mechanism 6. When the entire bundle of steel strands passes through the rotating ring 62, the rotating ring 62 rotates and winds the binding wire spiral around the steel strands. The bundled steel strands enter the threading mechanism 7, where the conveying chain 71 and clamping block 73 clamp the steel strands for further transport, so that the steel strands enter the second clamping mechanism 8. In the initial state, the second clamping cylinder 82 is in the retracted state, and only the second mounting base 81 supports and simply positions the steel strands. After the end of the steel strand is removed from the threading mechanism 7, the piston rod of the second clamping cylinder 82 extends, the second clamping block 83 clamps the steel strand, and the second mounting base 81 moves along the steel strand conveying direction to control the exposed length of the steel strand. The second clamping mechanism 8 moves laterally on the third guide rail 13, enabling it to move from one channel of the box girder to another, eliminating the need to move the entire threading trolley and facilitating quick positioning for threading the steel strand in the next channel.

[0037] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
