Description

Technical Field

[0001] This invention relates to the technical field of pipeline support construction, specifically to a rectangular corrugated steel cross-sectional area measurement and positioning component and a jacking pipe steel processing equipment. Background Technology

[0002] During the construction of subway tunnels and similar tunnels, it is necessary to pre-bury pipes for cable laying in areas such as under the tracks. At the same time, in order to avoid the impact of the large current in the cable on the equipment above, it is necessary to install jacking steel reinforcement inside the pre-buried concrete pipe. Jacking steel reinforcement is collectively referred to as rectangular corrugated steel reinforcement, which is a rectangular corrugated steel plate bent into a circular tube structure. During the bending process of the rectangular corrugated steel plate, due to the structure of the rectangular corrugated steel plate, the bending points are unevenly distributed during bending, and the two sides of the rectangular inner cavity expand or contract. After pouring, the structure of each part filled by concrete is not uniform. At the same time, there are bending lines on the outside of the rectangular corrugated steel reinforcement. When the concrete pipe is under pressure, these bending lines cause different bearing pressure at different locations, resulting in poor support effect. In addition, the measurement of the cross-sectional area of ​​the rectangular corrugated steel reinforcement is also subject to problems. Summary of the Invention

[0007] In one embodiment, a jacking steel frame processing device is also included, comprising a pre-bending mechanism. The pre-bending mechanism includes an extension block, which is vertically disposed on the side of the first bending rod away from the first bending rod. The extension block has a through guide groove in the middle along its length direction, and a lever is disposed in the guide groove. The second bending rod is also provided with an inclined extension block, one end of which is fixedly connected to the side of the second bending rod away from the second threaded rod.

[0008] In one embodiment, the actuating lever has a threaded rotating rod perpendicular to the axis of the actuating lever at its middle part.

The support rods pass through and slide in adjacent support lifting grooves in sequence. A thrust spring is provided between the support rods and the base plate and placed in the support lifting groove.

[0014] The beneficial effects of this invention are as follows: This invention provides a simple structure that effectively solves the problem of bending uniform rectangular corrugated steel plates, and also assists in measuring the cross-sectional area of ​​rectangular corrugated steel ribs and the processing equipment for jacking pipe ribs. The specific implementation method is as follows: First, after placing the rectangular corrugated steel plate on the positioning round plate, adjust the distance between the two supporting round plates of the positioning round plate, rotate the fixing screw to push the conical table to rotate, and drive the end of the fixing screw to abut against the inclined surface of the conical table to push the conical table to move, so that the two sets of supporting round plates abut against the two sides of the rectangular inner cavity of the rectangular corrugated steel plate. After all the positioning round plates are adjusted, bending can begin. After the rectangular corrugated steel plate is placed between two sets of guide conveying rollers on the conveyor, one end of the rectangular corrugated steel plate is pushed between the pressure roller and the positioning circular plate. Then, the drive motor is started to rotate the rolling shaft, causing the first rotating block to rotate. During the rotation of the first rotating block, the first rotating block drives the first bending rod and the first actuating block connected to the first bending rod to rotate. When the first actuating block rotates away from the supply direction of the rectangular corrugated steel plate, the support shaft on the second actuating block serves as the fulcrum of the rectangular corrugated steel plate. The pressure roller rotates along the axis of the rolling shaft to press the rectangular corrugated steel plate for bending. Due to the abutment action of the support circular plate on the support shaft against the inner side of the rectangular corrugated steel plate, the expansion or contraction of the inner side of the rectangular corrugated steel plate can be avoided when the first actuating block bends the rectangular corrugated steel plate, thus avoiding deformation after bending. To reduce the external fold lines generated after bending rectangular corrugated steel plates, which would affect the measurement and support effect of subsequent rectangular corrugated steel frame sections, the spacing between the support points of the support circular plate and the pressure roller needs to be adjusted during the bending process. When the first bending rod rotates, the extension block drives the actuating rod to rotate the second bending rod. The rotation of the second bending rod then drives the support shaft on the second actuating block to rotate. When the pressure roller rotates, the support circular plate on the support shaft can rotate with the pressure roller, thus changing the rotation fulcrum of the support circular plate relative to the pressure roller. This results in bending over a shorter bending pressure area, solving the problem of the pressure support point lifting off the surface of the support circular plate due to a longer pressure spacing. This effectively solves the problem of external fold lines generated after bending. At the same time, the bent rectangular corrugated steel frame will be more standard and regular, facilitating the measurement of the section. Meanwhile, to accommodate bending of rectangular corrugated steel frames with different radii and rectangular corrugated steel plates with different rectangular protrusion thicknesses, the second and first threaded rods can be rotated to push the second and first bending rods, causing the second and first actuating blocks to move away from the second and first rotating blocks. Simultaneously, the constraint effect of the oblique groove of the first bending rod causes the actuating rod to push the threaded rotating rod through the extension block. The height of the oblique groove can be wider than the diameter of the actuating rod, facilitating adjustment and changing the spacing to adapt to different bending requirements. Furthermore, larger rectangular corrugated steel frames can exhibit smaller and more uniform deformation during bending (i.e., smaller changes in the continuous tangent angle). The distance between the support plate as the support point and the pressing point of the pressing roller is required. When the first bending rod rotates, the length of the threaded rotating rod on the actuating rod extending out of the extension block is relatively large. That is, the actuating rod slides a long distance away from the second bending rod in the inclined groove in the inclined extension block. This causes the second bending rod to be actuated by the actuating rod with lag when the first bending rod rotates, and the rotation angle between the second bending rod and the first bending rod changes. This can effectively change the distance between the support plate as the support point and the pressing point of the pressing roller, thus speeding up the bending speed. The rotating nut increases the thrust of the actuating rod on the inclined extension block by rotating and abutting against the end of the guide groove on the extension block away from the rectangular corrugated steel plate. After bending is completed, the drive motor rotates in the opposite direction, so that the second and first actuating blocks return to their original positions, and the feeding and bending are repeated. At the same time, the bending area can overlap with the previous area to reduce the deformation of the zigzag line. After the rectangular corrugated steel plate is bent into a tube shape, it is overlapped onto the support rod on the top part. The support rod is pushed up and down in the support lifting groove by the thrust of the thrust spring to support the outer surface of the rectangular corrugated steel plate and restore the initial position of the pre-bending mechanism. Then, the cutting mechanism is started. The laser cutting machine is moved by the horizontal moving device to cut the rectangular corrugated steel plate. The rotating shaft of the reverse bending rotation drive motor drives the first actuating block to bend the rectangular corrugated steel plate. The pressure roller pushes the actuating rod on the first bending rod to press the second bending rod to rotate together, thus pressing the tail of the rectangular corrugated steel plate to bend. Since the front end of the rectangular corrugated steel plate is piled on the top part, the weight of the rectangular corrugated steel plate has already fixed the rectangular corrugated steel plate during bending. That is, a small amount of bending at the tail does not need to be supported by the supporting circular plate to occur. Meanwhile, since the rectangular corrugated steel plates have different thicknesses, the support plate can be raised by changing the height of the lifting cylinder, which will drive the guide conveying roller to move, making it easier for the rectangular corrugated steel plates to pass between the pressing roller and the support circular plate.

[0015] To measure the cross-sectional area of ​​the rectangular corrugated steel frame, the distance between the tangent point of the sliding tube furthest from the rolling axis and the center point of the rolling axis can be measured. Alternatively, the cross-sectional area can be calculated by taking the extension length of the rectangular corrugated steel plate and the angle between the first and second actuating blocks and the axis of the rolling axis. The equipment has a simple structure and effectively solves the problem of uniform bending of rectangular corrugated steel plates by changing the bending support point and supporting the inner cavity of the rectangular corrugated steel plate. At the same time, it can assist in the area measurement of the rectangular corrugated steel frame. It has good practicality and economy, which is beneficial to the promotion and use of the equipment.

A second height adjustment component is provided between the first rotating block 43 and the adjacent first actuating block 45 to adjust the relative distance between the first actuating block 45 and the first rotating block 43.

[0022] Beneficially, the first height adjustment component includes a second bending rod 463, which has an L-shaped structure. The long end of the second bending rod 463 is fixedly connected to the side of the second actuating block 462 near the second rotating block 46. The second rotating block 46 is also provided with a second threaded rod 461. One end of the second threaded rod 461 is rotatably connected to the side of the second rotating block 46 near the second actuating block 462. The second threaded rod 461 penetrates vertically and is threadedly connected to the short end of the second bending rod 463. The first height adjustment component includes a first bending rod 44, which has an L-shaped structure. The long end of the first bending rod 44 is fixedly connected to the side of the first actuating block 45 near the first rotating block 43. The first rotating block 43 is also provided with a first threaded rod 431. One end of the first threaded rod 431 is rotatably connected to the side of the first rotating block 43 near the first actuating block 45. The first threaded rod 431 penetrates vertically and is threadedly connected to the short end of the first bending rod 44.

[0023] Beneficially, the positioning circular plate includes two supporting circular plates 48, with a supporting shaft 47 passing through and slidably connected to the center of the supporting circular plates 48. Sliding tubes 481 and conical pedestals 482 are respectively provided on opposite sides of the two sets of supporting circular plates 48, both of which are passed through and slidably connected by the supporting shaft 47. The conical end of the conical pedestal is inserted into the inner cavity of the sliding tube 481. Several fixing screws 483 are provided around the sliding tube 481, and the fixing screws 483 are threadedly connected to the sliding tube 481 and abut against the periphery of the conical pedestal 482.

[0024] Beneficially, it also includes a pipe jacking steel frame processing equipment, including a pre-bending mechanism 4. The pre-bending mechanism 4 includes an extension block 441, which is vertically disposed on the side of the first bending rod 44 away from the first bending rod 44. The middle of the extension block 441 is provided with a through guide groove 4411 along the length direction. A lever 442 is disposed in the guide groove 4411. The second bending rod 463 is also provided with an inclined extension block 4631. One end of the inclined extension block 4631 is fixedly connected to the side of the second bending rod 463 away from the second threaded rod 461. The end of the inclined extension block 4631 away from the second bending rod 463 is inclined towards the second lever 462. The middle of the inclined extension block 4631 is provided with an inclined groove 4632 that runs through the length direction of the inclined extension block 4631. The end of the lever 442 away from the extension block 441 passes into and is slidably connected to the inclined groove 4632.

[0025] In practice, to accommodate bending of rectangular corrugated steel frames with different radii and rectangular corrugated steel plates 11 with different rectangular protrusion thicknesses, the second threaded rod 461 and the first threaded rod 431 can be rotated to push the second bending rod 463 and the first bending rod 44 to move the second actuating block 462 and the first actuating block 45 away from the second rotating block 46 and the first rotating block 43. At the same time, the constraint effect of the inclined groove 4632 of the first bending rod 44 drives the actuating rod 442 to push the threaded rotating rod 443 through the extension block 441. The height of the inclined groove 4632 can be wider than the diameter of the actuating rod 442, which is convenient for adjustment and can change its spacing to adapt to different bending requirements.

[0026] Beneficially, the actuating lever 442 has a threaded rotating lever 443 perpendicular to the axis of the actuating lever 442 in the middle. The threaded rotating lever 443 passes through and is slidably connected to the end of the extension block 441 away from the first bending lever 44. The threaded rotating lever 443 has a rotating nut 444 in the middle. The rotating nut 444 is located in the guide groove 4411 and is threadedly connected to the threaded rotating lever 443.

[0027] Beneficially, the first bending rod 44 is also provided with several conveying components 3 on the side near the extension block 441, for conveying the rectangular corrugated steel plate 11 into the space between the pressing roller 451 and the positioning circular plate. The conveying component 3 includes two sets of guide conveying rollers 32, and the two ends of the two sets of guide conveying rollers 32 are provided with support plates 31. The guide conveying rollers 32 pass through and are rotatably connected to the support plates 31. A lifting cylinder 33 is provided between the support plate 31 and the bottom plate 1.

[0028] Beneficially, the guide conveyor roller is driven to rotate by a motor; or the rectangular corrugated steel plate 11 moves and drives the rotation.

[0029] Beneficially, a cutting mechanism 2 is also provided on the side of the conveyor 3 away from the base plate 1. The cutting mechanism 2 includes a laser cutter 21 and a transverse moving device 22 that facilitates the movement of the support plate 31. The laser cutter 21 is a commonly used device for cutting sheet metal. The transverse moving device 22 can realize the movement of the laser cutter 21 and can be configured according to the actual situation. It is not an inventive point of this invention, so it will not be described in detail. The cutting mechanism 2 is placed on the base plate 1.

[0030] Beneficially, the pre-bending mechanism 4 is also provided with a top part 5 on the side near the base plate 1. The top part 5 is used to support the bent rectangular corrugated steel plate 11. Specifically, the top part 5 includes several support rods 51. The axis of the support rods 51 is parallel to the axis of the rolling shaft 42. The two ends of the several support rods 51 are provided with support lifting plates 52 placed on the base plate 1. The support lifting plates 52 are provided with several support lifting grooves 521 along the direction away from the base plate 1. The several support lifting grooves 521 are arranged in an axial array along the length direction of the support lifting plates 52. The support rods 51 pass through and slide in adjacent support lifting grooves 521 in sequence. A thrust spring 522 is provided between the support rods 51 and the base plate 1 and placed in the support lifting groove 521.

[0031] Working principle of this invention: First, after placing the rectangular corrugated steel plate 11 on the positioning round plate, adjust the distance between the two supporting round plates 48 of the positioning round plate, rotate the fixing screw 483 to push the conical platform 482 to rotate, and drive the end of the fixing screw 483 to abut against the inclined surface of the conical platform 482 to push the conical platform to move, so that the two sets of supporting round plates 48 abut against the two sides of the rectangular inner cavity of the rectangular corrugated steel plate 11. After all the positioning round plates are adjusted, bending can begin. After the rectangular corrugated steel plate 11 is placed between the two sets of guide conveying rollers 32 on the conveyor 3, one end of the rectangular corrugated steel plate 11 is pushed between the pressing roller 451 and the positioning circular plate. Then, the drive motor 421 is started to rotate the rolling shaft 42, causing the first rotating block 43 to rotate. During the rotation of the first rotating block 43, the first rotating block 43 drives the first bending rod 44 and the first actuating block 45 connected to the first bending rod 44 to rotate. The first actuating block 45 moves away from the rectangular corrugated steel plate 11. When the direction is rotated, the support shaft 47 on the second actuating block 462 serves as the fulcrum of the rectangular corrugated steel plate 11. The pressing roller 451 rotates along the axis of the rolling shaft 42 to press the rectangular corrugated steel plate 11 for bending. Due to the abutment action of the support circular plate 48 on the support shaft 47 against the inner side of the rectangular corrugated steel plate 11, the expansion or contraction of the inner side of the rectangular corrugated steel plate 11 can be avoided when the first actuating block 45 bends the rectangular corrugated steel plate 11, thus avoiding deformation of the rectangular corrugated steel plate 11 after bending. To reduce the external fold lines generated after bending the rectangular corrugated steel plate 11, which would affect the measurement and support effect of the subsequent rectangular corrugated steel frame section, the spacing between the support points of the support plate 48 needs to be adjusted when the pressure roller 451 is pressing and bending. When the first bending rod 44 rotates, the extension block 441 drives the actuating rod 442 to rotate the second bending rod 463. The rotation of the second bending rod 463 drives the support shaft 47 on the second actuating block 462 to rotate. When the pressure roller 451 rotates, the support plate 48 on the support shaft 47 can rotate with the pressure roller 451, which changes the rotation fulcrum of the support plate 48 on the pressure roller 451. This results in bending with a shorter bending pressing area, solving the problem of the pressure support point lifting off the surface of the support plate 48 due to the long pressing spacing. This effectively solves the problem of the external fold lines generated after bending. At the same time, the bent rectangular corrugated steel frame will be more standard and regular, which is convenient for the measurement of the section. Meanwhile, to accommodate bending of rectangular corrugated steel frames with different radii and rectangular corrugated steel plates 11 with different rectangular protrusion thicknesses, the second threaded rod 461 and the first threaded rod 431 can be rotated to push the second bending rod 463 and the first bending rod 44 to move the second actuating block 462 and the first actuating block 45 away from the second rotating block 46 and the first rotating block 43. At the same time, the constraint effect of the inclined groove 4632 of the first bending rod 44 drives the actuating rod 442 to push the threaded rotating rod 443 out of the extension block 441. The height of the inclined groove 4632 can be wider than the diameter of the actuating rod 442, which is convenient for adjustment and can change its spacing to adapt to different bending requirements. At the same time, since larger rectangular corrugated steel frames can have smaller and more uniform deformation (i.e., smaller changes in the continuous tangent angle) during bending, a supporting circular plate 48 is required as a support. The distance between the support point and the pressing point of the pressing roller 451 is relatively large when the first bending rod 44 rotates. The threaded rotating rod 443 on the actuating rod 442 extends out of the extension block 441 for a relatively large length. That is, the actuating rod 442 slides a long distance away from the second bending rod 463 in the inclined groove 4632 in the inclined extension block 4631. This causes the second bending rod 463 to be delayed by the actuating rod 442 when the first bending rod 44 rotates. The rotation angle between the second bending rod 463 and the first bending rod 44 changes, which can effectively change the distance between the support plate 48 as the support point and the pressing point of the pressing roller 451, thus speeding up the bending speed. The rotating nut 444 increases the thrust of the actuating rod 442 on the inclined extension block 4631 by rotating and abutting against the end of the guide groove 4411 on the extension block 441 away from the rectangular corrugated steel plate 11. After bending is completed, the drive motor 421 is rotated in the opposite direction, so that the second actuating block 462 and the first actuating block 45 return to their original positions, and the feeding and bending are repeated. At the same time, the bending area can overlap with the previous area to reduce the deformation of the fold line. After the rectangular corrugated steel plate 11 is bent into a tube shape, it is overlapped onto the support rod 51 on the top part 5. The support rod 51 is pushed up and down in the support lifting groove 521 by the thrust of the thrust spring 522 to support the outer surface of the rectangular corrugated steel plate 11 and restore the initial position of the pre-bending mechanism 4. Then, the cutting mechanism 2 is started. The laser cutting machine 21 is moved by the horizontal moving device 22 to cut the rectangular corrugated steel plate 11. The rotating shaft of the reverse bending rotation drive motor 421 drives the first actuating block 45 to bend the rectangular corrugated steel plate 11. The pressing roller 451 pushes the actuating rod 442 on the first bending rod 44 to press the second bending rod 463 to rotate together, so that the tail of the rectangular corrugated steel plate 11 can be bent. Since the front end of the rectangular corrugated steel plate 11 is piled on the top part 5, the weight of the rectangular corrugated steel plate 11 has already fixed the rectangular corrugated steel plate 11 during bending. That is, the small amount of bending at the tail does not need to be supported by the supporting circular plate 48 to occur. Meanwhile, since the rectangular corrugated steel plate 11 has different thicknesses, the support plate 31 can be raised by changing the height of the lifting cylinder 33, which will drive the guide conveying roller to move, so that the rectangular corrugated steel plate 11 can be passed between the pressing roller 451 and the support circular plate 48.

[0032] To measure the cross-sectional area of ​​the rectangular corrugated steel frame, the cross-sectional area can be effectively measured by measuring the distance between the tangent point of the sliding tube 481 away from the rolling shaft 42 and the center point of the rolling shaft 42. Alternatively, the cross-sectional area can be calculated by measuring the axial length of the extended length of the rectangular corrugated steel plate 11 and the angle between the first actuating block 45, the second actuating block 462 and the axis of the rolling shaft 42.
