Description

Technical Field

[0001] The invention belongs to pipe segment processing equipment, and relates to a prefabricated pipe segment turning and polishing equipment. Background Art

[0002] Prefabricated high-strength concrete segments are arc-shaped components made of a mixture of cement, gravel, sand and water. They are usually made through the following steps: mold cleaning and oiling, mold assembly, steel skeleton and embedded parts installation, concrete pouring and vibration, concrete molding and plastering, steam curing and subsequent surface treatment, and then transported to designated storage areas.

[0003] After steam curing, the hardening of the concrete segments can be accelerated and the early strength can be improved. However, the surface of the segments is still relatively rough at this time, and the concrete segments need to be surface treated. The commonly used surface treatment is polishing to improve the smoothness of the segments. When the segments are prepared, the outer arc surface is often facing up, and the segments with the outer arc surface facing up are often not convenient to stack. Therefore, before transporting the segments, the segments need to be turned over so that the inner arc surface of the segments faces up. At this time, the two ends of the next layer of segments can limit the upper layer of segments. When stacking, the upper and lower layers have better stability and are also convenient for handling.

[0004] However, the existing polishing method is to polish the inner and outer arc surfaces of the pipe segment by the staff, and then turn it over for transportation. Before turning over, since the inner arc surface of the pipe segment is facing downward, it is very inconvenient for the staff to polish the inner arc surface of the pipe segment, which easily leads to low efficiency of the polishing step. If the pipe segment is turned over during the polishing process, the pipe segment needs to be clamped again after polishing and transported to the stacking position. This method has many processes and also reduces the overall preparation efficiency of the pipe segment. Summary of the invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a prefabricated pipe segment flipping and polishing equipment, which can facilitate the polishing of the pipe segments and directly stack them after polishing, making it convenient to carry the stacked pipe segments and effectively improving the overall preparation efficiency.

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] Reference Figures 1 to 9 A prefabricated pipe segment flipping and polishing device comprises a flipping frame 1, a flipping rod 11, a clamping assembly 2, a polishing assembly 3, a discharging drive assembly 4 and a stacking seat 6; the flipping frame 1 has an inlet 12 and a discharging port 13, the flipping rod 11 is rotatably arranged on the flipping frame 1 and is located between the inlet 12 and the discharging port 13, the clamping assembly 2 is arranged on the flipping rod 11, and the clamping assembly 2 can clamp the pipe segment 7. When the pipe segment 7 is at the inlet 12, the outer arc of the pipe segment 7 is facing upward, and the outer arc surface of the pipe segment 7 is manually polished. Afterwards, the flip rod 11 is rotated to make the pipe segment 7 located at the discharge port 13. At this time, the inner arc of the pipe segment 7 faces upward. The polishing assembly 3 is arranged on the flip frame 1. The polishing assembly 3 can polish the inner arc of the pipe segment 7. The discharge driving assembly 4 is arranged on the flip frame 1 and can drive the flip rod 11 to move toward the discharge port 13. The stacking seat 6 is arranged at the discharge port 13. After the polishing of the pipe segment 7 is completed, the discharge driving assembly 4 can drive the pipe segment 7 to move toward the discharge port 13 and stack it on the stacking seat 6.

[0031] Reference Figure 3 and Figure 4 The clamping assembly 2 includes a clamping table 21, a first clamping rod 22, a first clamping cylinder 23, a second clamping rod 24, and a second clamping cylinder 25; in the present application, there are two clamping tables 21, and the two clamping tables 21 are rotated 180° relative to the rotation axis of the flip rod 11, so that when one of the clamping tables 21 is at the inlet 12 of the flip frame 1, the other clamping table 21 is just located at the outlet 13 of the flip frame 1. In this way, when the outer arc surface of the tube segment 7 at the inlet 12 is polished, the inner arc surface of the tube segment 7 at the inlet 12 can also be polished. In the present application, the outer arc surface is polished manually, and the inner arc surface is polished by the polishing assembly 3.

[0032] Reference Figure 3 and Figure 4 Specifically, the first clamping rod 22 is slidably disposed on the clamping platform 21, the first clamping cylinder 23 is fixedly disposed on the clamping platform 21, and the output end of the first clamping cylinder 23 is fixedly connected to the first clamping rod 22, and can drive the first clamping rod 22 to slide. The second clamping rod 24 is also slidably disposed on the clamping platform 21, and the second clamping rod 24 is disposed opposite to the first clamping rod 22, the second clamping cylinder 25 is fixedly disposed on the clamping platform 21, and the output end of the second clamping cylinder 25 is fixedly connected to the first clamping rod 22, and can drive the second clamping rod 24 to slide.

[0033] Reference Figure 3 and Figure 4 The first clamping rod 22 and the second clamping rod 24 can approach or move away from each other under the drive of the first clamping cylinder 23 and the second clamping cylinder 25. A clamping area 26 is formed between the first clamping rod 22 and the second clamping rod 24. The clamping area 26 is used to accommodate the pipe segment 7. The first clamping rod 22 and the second clamping rod 24 are used to clamp the pipe segment 7.

[0034] In order to improve the clamping effect, there are two first clamping rods 22 and two first clamping cylinders 23, and there are two second clamping rods 24 and two second clamping cylinders 25.

[0035] Reference Figure 3 and Figure 4 Taking the clamping table 21 at the feed port 12 as an example, the first clamping rod 22 is located above the segment 7. After the segment 7 is transferred to the clamping table 21 at the feed port 12, the two second clamping rods 24 are used to support the segment 7, and then the first clamping rod 22 moves upward so that there is a certain space between the first clamping rod 22 and the outer arc surface of the segment 7, thereby facilitating the staff to polish the outer arc surface of the segment 7.

[0036] Reference Figure 3 and Figure 4When the outer arc surface of the tube segment 7 is polished, the first clamping rod 22 will move downward to clamp the outer arc surface of the tube segment 7. Then the flip rod 11 is rotated to flip the clamping platform 21 originally located at the inlet 12 to the outlet 13. At this time, the two second clamping rods 24 are located above the tube segment 7. The two first clamping rods 22 are used to support the tube segment 7. When the inner arc surface of the tube segment 7 needs to be polished, the second clamping rod 24 is first moved upward so that there is a certain space between the second clamping rod 24 and the inner arc surface of the tube segment 7, so as to facilitate the polishing assembly 3 to polish the inner arc surface of the tube segment 7.

[0037] Reference Figure 3 and Figure 5 The polishing assembly 3 includes a swing arm 31, a polishing rod 32, a polishing disc 33, a first polishing drive assembly 34, a second polishing drive assembly 35 and a third polishing drive assembly 36; the upper end of the swing arm 31 is rotatably set on the flip frame 1, and the lower end is transmission-connected with the polishing rod 32. There are multiple polishing discs 33, and the polishing discs 33 are rotatably set on the polishing rod 32. The polishing rod 32 is equipped with a motor for driving the polishing discs 33 to rotate. The polishing discs 33 are used to polish the inner arc surface of the pipe segment 7.

[0038] Reference Figure 3 and Figure 5 The first polishing drive assembly 34 can drive the swing arm 31 to swing, and the upper end of the swing arm 31 is colinear with the axis of rotation of the flip frame 1 and the arc center axis of the inner arc surface of the pipe segment 7. When the swing arm 31 swings, the polishing disc 33 on the flip rod 11 can move along the surface of the inner arc surface of the pipe segment 7, thereby performing polishing.

[0039] Reference Figure 3 and Figure 5 The first polishing drive assembly 34 includes an arc-shaped rack 341, a first polishing gear 342 and a first polishing motor 343; the arc-shaped rack 341 is fixedly arranged on the flip frame 1, and the arc center axis of the arc-shaped rack 341 is colinear with the axis of rotation of the swing arm 31, the first polishing gear 342 is rotatably arranged on the swing arm 31, and the first polishing gear 342 is meshed with the arc-shaped rack 341. The first polishing motor 343 is also fixedly arranged on the swing arm 31, and the output shaft of the first polishing motor 343 is fixedly connected with the first polishing gear 342, which can drive the first polishing gear 342 to rotate, thereby swinging the swing arm 31.

[0040] Reference Figure 3 and Figure 5The second polishing drive assembly 35 can drive the swing arm 31 to extend or shorten. Specifically, the swing arm 31 includes a rotating rod 311 and a telescopic rod 312. The second polishing drive can drive the telescopic rod 312 to move relative to the length direction of the rotating rod 311, thereby realizing the extension or shortening of the swing arm. The first polishing drive assembly 34 mainly drives the rotating rod 311 to swing. The first polishing wheel and the first polishing drive are arranged on the rotating rod 311, so that the telescopic rod 312 can be driven by the swing of the rotating rod 311. Thus, synchronous movement is realized.

[0041] Reference Figure 3 and Figure 5 The second polishing drive assembly 35 includes a polishing cylinder 351, a guide groove 352 and a guide protrusion 353; the polishing cylinder 351 is fixedly arranged on the rotating rod 311, and the output end of the polishing cylinder 351 is fixedly connected to the telescopic rod 312. The polishing cylinder 351 can drive the telescopic rod 312 to slide along the length direction of the rotating rod 311. The guide groove 352 is opened at the lower end of the rotating rod 311, and the guide protrusion 353 is fixed at the upper end of the telescopic rod 312. The guide protrusion 353 is located in the guide groove 352. As the swing arm 31 is extended or shortened, the guide protrusion 353 can move on the guide groove 352.

[0042] Reference Figure 3 and Figure 5 The third polishing drive assembly 36 can drive the polishing rod 32 to move relative to the swing arm 31, so that the polishing plate 33 on the polishing rod 32 can move along the width direction of the pipe segment 7 and polish.

[0043] Reference Figure 3 and Figure 5 The third polishing drive assembly 36 includes a second polishing gear 361, a convex tooth 362, a second polishing motor 363 and a guide rod 364; the second polishing gear 361 is rotatably arranged on the telescopic rod 312, the second polishing motor 363 is fixedly arranged on the telescopic rod 312 and the output shaft of the second polishing motor 363 is rotatably connected to the second polishing gear 361, and can drive the second polishing gear 361 to rotate, the convex tooth 362 is fixedly connected to the polishing rod 32, and the convex tooth 362 is meshed with the second polishing gear 361; one end of the guide rod 364 is fixedly connected to the polishing rod 32, and the other end is slidably connected to the telescopic rod 312. With the rotation of the second polishing gear 361, the polishing rod 32 can slide relative to the telescopic rod 312, and the guide rod 364 also slides relative to the telescopic rod 312. In the present application, the guide rod 364 plays a guiding role, so that the movement of the polishing rod 32 is more stable.

[0044] Reference Figure 6 and Figure 7After the inner arc surface of the pipe segment 7 is polished, a shelf rod 5 is placed on the inner arc surface. The shelf rod 5 is a rectangular long wooden rod. After the shelf rod 5 is placed on the inner arc surface of the pipe segment 7, another pipe segment 7 can be conveniently placed on the pipe segment 7. The shelf rod 5 is mainly used to provide a gap between two adjacent, superimposed pipe segments 7, which can facilitate the transportation of a single pipe segment 7 when the tunnel is spliced ​​later.

[0045] Reference Figure 6 and Figure 7 The flip frame 1 is provided with a receiving groove 51, in which a plurality of shelf rods 5 are placed, a through groove 52 is provided at the bottom of the receiving groove 51, and a placement piece 53 is also provided in the receiving groove 51. A placement driving cylinder 57 is provided on the flip frame 1, and the placement driving cylinder 57 can drive the placement piece 53 to move downward. The placement piece 53 is provided with a placement groove 54. When the placement piece 53 is at the highest position, the placement groove 54 is connected with the through groove 52, and the shelf board in the receiving groove 51 will enter the placement groove 54 through the through groove 52.

[0046] Reference Figure 6 and Figure 7 A rotating plate 55 is provided at the bottom of the placement groove 54, and the shelf rod 5 in the placement groove 54 is supported by the rotating plate 55. A protrusion 56 is provided on the lower surface of the rotating plate 55, and the protrusion 56 is located directly above the second clamping rod 24. The driving cylinder moves downward, and the second clamping rod 24 moves upward at the same time. The second clamping rod 24 pushes against the protrusion 56 to rotate the rotating plate 55. After the rotating plate 55 rotates and tilts, the shelf rod 5 originally on the rotating plate 55 will fall into the inner arc surface of the pipe segment 7.

[0047] Since two placing rods 5 are needed to support the pipe segment 7, there are two placing grooves 54, two placing driving cylinders 57 and two placing members 53, which are symmetrically arranged on the turning frame 1.

[0048] Reference Figure 1 and Figure 8 , the discharging drive assembly 4 has two groups, which are respectively connected to the flip rods 11 at both ends. The discharging drive assembly 4 includes a slide 41, a slider 42 and a driving rod 43. The slide 41 is opened on the flip frame 1, and the slider 42 is slidably set in the slide 41. The flip rod 11 is rotatably set in the slider 42. The slider 42 is also provided with a flip click. The output shaft of the flip motor is connected to the flip rod 11 and can drive the flip rod 11 to rotate. The driving rod 43 is threadedly connected to the slider 42. A motor that can rotate the driving rod 43 is provided in the flip frame 1. After the motor rotates the driving rod 43, the slider 42 can move in the slide 41. The driving rod 43 is provided with a thread, which is not shown in the figure. The driving rod 43 and the slider 42 are driven by a screw.

[0049] Reference Figure 2and Fig. 9 When the placing rod 5 is placed on the inner arc surface of the pipe segment 7, the discharging driving assembly 4 moves the flip rod 11 toward the discharging port 13, so that the pipe segment 7 originally at the position of the discharging port 13 moves to the top of the stacking seat 6, and the stacking seat 6 can stack the pipe segment 7.

[0050] Reference Figure 2 and Fig. 9 Two buffer plates 65 are fixed on the upper surface of the stacking seat 6 for supporting the bottom segment 7. Slide rails 61 are arranged on both sides of the stacking seat 6. A slide table 62 is slidably connected to the slide rails 61. A lifting cylinder 63 is fixed on the slide table 62. The output end of the lifting cylinder 63 is arranged at the upper part. A lifting seat 64 is fixed to the output end of the lifting cylinder 63. The curvature of the upper surface of the lifting seat 64 is consistent with the curvature of the outer arc surface of the segment 7.

[0051] Reference Figure 2 and Fig. 9 In the case where there are already segments 7 on the stacking seat 6, when it is necessary to put the segments 7 at the discharge port 13 on the stacking seat 6, the lifting cylinder 63 first drives the lifting seat 64 to move upward, pushing the segments 7 originally on the buffer plate 65 to move upward, making room for the buffer plate 65, and then the discharge drive assembly 4 moves the segments 7 at the discharge port 13 to just above the buffer plate 65, and then rotates the flip rod 11 so that the segments 7 can abut against the buffer plate 65. Then the discharge drive assembly 4 resets the flip rod 11, and then the lifting seat 64 moves downward so that the segments 7 on the lifting seat 64 can be supported on the segments 7 already placed on the buffer plate 65. There is also a cylinder inside the stacking seat 6 that can drive the slide 62 to move, so that the slide 62 moves relative to the slide rail 61, so that the lifting seat 64 is away from the segments 7, and finally located below the two ends of the lowest segments 7.
