Abstract
Description
Technical Field
[0001] This invention relates to the field of beam I-beam straightening technology, and more specifically, to an all-purpose semi-trailer beam I-beam straightening device. Background Technology
[0002] As a core load-bearing component of a semi-trailer, the structural precision of the I-beams in the main beam directly determines the vehicle's load-bearing capacity, driving stability, and service life. During the manufacturing process, after welding, cutting, and heat treatment, the I-beams are prone to bending, twisting, or flange deformation due to stress release and uneven localized stress. During long-term use, factors such as heavy loads and bumpy road conditions may also cause plastic deformation. If not effectively corrected, this can lead to an imbalance in the semi-trailer frame's stress, causing uneven tire wear, abnormal braking systems, and even safety accidents such as frame breakage during operation.
[0003] Existing equipment often uses fixed-shape calibration molds, which cannot be flexibly adjusted according to parameters such as the flange width of the I-beam. When calibrating I-beams of different specifications, the entire set of tooling must be replaced after machine shutdown, increasing preparation time, reducing equipment utilization, and potentially causing positioning accuracy deviations due to frequent disassembly and assembly. Furthermore, key components in contact with the I-beam are prone to wear under long-term compression and friction. In existing designs, these components are usually fixed to the main structure, requiring complete replacement after wear, increasing spare parts costs and extending production cycles due to downtime maintenance. During calibration, when the length of the I-beam exceeds the equipment's support range, the end furthest from the calibration equipment will sag due to its own weight, causing the I-beam to enter the calibration area at an angle. This tilting causes uneven stress on the calibration mechanism, concentrating the calibration stress on the web and flanges locally. This not only affects the straightness after calibration but may also cause deformation or leakage in core components such as guide components and pressure cylinders due to long-term uneven loading, shortening the equipment's service life. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides an all-purpose semi-trailer beam I-beam straightening device.
[0005] The technical solution is as follows:
[0006] A versatile semi-trailer beam I-beam straightening device includes a straightening base and two sets of vertical beam plates. Both sets of vertical beam plates are fixed on the top of the straightening base. Each set of vertical beam plates has two plates. A lifting plate slides between the two vertical beam plates of each set. A straightening component is installed on the straightening base and between the two lifting plates. Support components for stabilizing and providing real-time support for the beam I-beam are installed on both sides of the straightening base.
[0007] The correction assembly includes two rotating cylinders that rotate on two lifting plates. Each rotating cylinder has a fixed shaft installed on its side that is close to each other. Each fixed shaft has a threaded sleeve and a side plate on its outer surface. Both the threaded sleeve and the side plate can slide horizontally on the fixed shaft to accommodate I-beams of different sizes.
[0008] The support assembly includes two base plates fixedly connected to both sides of the correction base. Each base plate is provided with a movable seat. Above each movable seat is a sliding frame for supporting the main beam I-beam. Above the sliding frame are two clamping plates for clamping the main beam I-beam.
[0009] Furthermore, a control panel is fixedly connected to the upright beam plate, and a hydraulic telescopic rod is fixedly connected between the two upright beam plates in each group. The two lifting plates are fixedly connected to the two hydraulic telescopic rods respectively. A transmission module is set on both sides of the top of the correction base. The transmission module consists of two rotatable transmission rollers. The top transmission roller is rotatably connected to the lifting plate, and the bottom transmission roller is rotatably connected to the correction base and driven to rotate by a motor.
[0010] Furthermore, the calibration assembly also includes a threaded column with two fixed shafts that are close to each other at one end and are fixedly connected together. Two threaded sleeves are threadedly connected to the adjacent threaded column. A fixing ring is fixedly connected to the middle of the outer surface of the threaded column. The two threaded sleeves are symmetrically arranged about the fixing ring. Multiple limiting blocks are fixedly connected to the surfaces of the two threaded sleeves that are far apart from each other. Two electric telescopic rods are fixedly connected to the surfaces of the two rotating cylinders that are close to each other. Two sets of electric telescopic rods on the same side are arranged as a group. The telescopic shafts of the two sets of electric telescopic rods are fixedly connected to an adjacent side plate. A limiting ring is fixedly connected to the surfaces of the two side plates that are close to each other.
[0011] Furthermore, there are two calibration components. One calibration component is located between the two lifting plates, and the other calibration component is located on the calibration base. The calibration component located on the calibration base is driven by a motor to rotate.
[0012] Furthermore, both side discs have protrusions that are adapted to the strip grooves fixedly connected to their inner sides. The side discs can only slide horizontally on the fixed shaft. The limiting ring has multiple grooves that are adapted to the limiting blocks on the side away from the side discs.
[0013] Furthermore, both base plates are provided with sliding grooves, and the two movable seats are slidably connected inside the two sliding grooves. The outer walls of both movable seats are rotatably connected with two sets of upper and lower rollers, each set consisting of four rollers. The two sets of rollers roll against the upper and lower surfaces of the base plates. Lifting sleeves are fitted on the outer surfaces of both movable seats, and fixed frames are fixedly connected to the tops of the two lifting sleeves. The sliding frames are slidably connected inside the fixed frames. Threaded grooves are provided in the middle of both movable seats, and through holes corresponding to the threaded grooves of the movable seats are provided in the middle of the two fixed frames. Threaded rods are threadedly connected to the threaded grooves of both movable seats. The tops of the threaded rods pass through the through holes of the fixed frames. Multiple balls arranged in a circular array are slidably connected between the outer surface of the threaded rods and the inner sidewall of the through holes of the fixed frames. Rotating frames are fixedly connected to the tops of the two threaded rods. Slots corresponding to the rotating frames are provided on the side walls of both fixed frames, and the rotating frames protrude from the fixed frames through the slots of the fixed frames.
[0014] Furthermore, one of the movable seats is located at the end of the base plate away from the calibration base, and the other movable seat is located at the end of the base plate closer to the calibration base. The outer surface of the rotating frame is provided with a rough texture.
[0015] Furthermore, the support assembly also includes two upright plates fixedly connected to the top of the two sliding frames. Electric cylinders are fixedly connected to the opposite sides of the two upright plates. The telescopic shafts of the two electric cylinders pass through the adjacent upright plates. Two clamping plates are fixedly connected to the ends of the two electric cylinder telescopic shafts that protrude from the upright plates. The adjacent sides of the two clamping plates are both set with a rough texture.
[0016] Based on the above, the beneficial effects of the all-purpose semi-trailer beam I-beam straightening device of the present invention are as follows:
[0017] By adjusting the threaded sleeve and side plate to adapt to I-beams of different sizes, precise fit with the flange and web contours of I-beams of different sizes is ensured, improving equipment utilization and achieving universality for I-beams of different sizes. Adjustment can also be made after wear of the threaded sleeve or side plate, i.e., when the distance between the threaded sleeve and side plate does not fit the flange of the I-beam, the distance between the threaded sleeve and side plate can be adjusted, thereby effectively enabling the threaded sleeve and side plate to squeeze and correct the flange of the I-beam. Compared with existing correction equipment that can only be replaced after wear, the adjustable design can improve service life.
[0018] By using a sliding frame to effectively support the main beam I-beam in real time, it is possible to prevent the end of the main beam I-beam away from the correction base from drooping during the correction process. Furthermore, it can ensure that the main beam I-beam enters the interior of the vertical beam plate in a horizontal posture for correction, avoiding tilting and causing uneven stress on the correction equipment, and reducing the uneven load of the main beam I-beam on the correction equipment.
[0019] By using clamping plates and fixing frames to restrict the sliding frame, the swaying of the main beam I-beam can be limited, preventing large-scale swaying and thus reducing the risk of injury to surrounding personnel and equipment, ensuring the safety of the main beam I-beam alignment process.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0035] The embodiments provided by the present invention will be described in detail below:
[0036] like Figures 1 to 6 As shown, an all-purpose semi-trailer beam I-beam straightening device includes a straightening base 1. Four upright beams 2 are fixedly connected to the top of the straightening base 1. The four upright beams 2 are arranged in two groups of two. A control panel 3 is fixedly connected to one of the upright beams 2. A hydraulic telescopic rod 4 is fixedly connected between the two upright beams 2 in each group. The two hydraulic telescopic rods 4 include a telescopic end and a fixed end. The fixed ends of the two hydraulic telescopic rods 4 are fixedly connected to the adjacent upright beams 2. Lifting plates 5 are fixedly connected to the bottom of the telescopic shafts of the two hydraulic telescopic rods 4. Transmission modules 8 for stable conveying of the beam I-beams are arranged on both sides of the top of the straightening base 1. A straightening component is arranged on the straightening base 1 and between the two lifting plates 5.
[0037] It should be noted that the transmission module 8 consists of two rotatable transmission rollers. The transmission roller at the top of the transmission module 8 is rotatably connected to the lifting plate 5. That is, when the lifting plate 5 moves up and down, it can drive one of the transmission rollers at the top of the transmission module 8 to move up and down synchronously. The transmission roller at the bottom of the transmission module 8 is rotatably connected to the correction base 1 and is driven to rotate by a motor.
[0038] The correction assembly includes two rotating cylinders 61 rotatably connected to two lifting plates 5. A fixed shaft 62 is fixedly connected to the side of each rotating cylinder 61 that is close to each other. A threaded post 63 is fixedly connected to the end of each fixed shaft 62 that is close to each other. A fixed ring 64 is fixedly connected to the middle of the outer surface of the threaded post 63. Two threaded sleeves 65, symmetrical about the fixed ring 64, are threadedly connected to the outer surface of the threaded post 63. Multiple limiting blocks 66 arranged in a circular array are fixedly connected to the side surfaces of the two threaded sleeves 65 that are far from each other. Two electric telescopic rods 67 are fixedly connected to the side of each rotating cylinder 61 that is close to each other. Two sets of electric telescopic rods 67 are provided on the same side. A side plate 68 is fixedly connected to the telescopic shaft of each set of electric telescopic rods 67. The two side plates 68 slide on a nearby fixed shaft 62. A limiting ring 69 is fixedly connected to the side surfaces of the two side plates 68 that are close to each other. Support assemblies for stabilizing and providing real-time support for the I-beams of the main beam are provided on both sides of the correction base 1.
[0039] It should be noted that there are two correction components. One correction component is set between the two lifting plates 5, and the other correction component is set on the correction base 1. The correction base 1 is equipped with a motor. The correction component set on the correction base 1 is connected by the output shaft of the motor. That is, the rotating cylinder 61 of the correction component set on the correction base 1 is driven to rotate by the motor. The upper and lower surfaces of the two fixed shafts 62 are provided with strip grooves. The inner sides of the two side plates 68 are fixedly connected with protrusions that are adapted to the strip grooves. The protrusions of the side plates 68 slide in the strip grooves of the fixed shafts 62, which can restrict the side plates 68 from rotating. The side plates 68 can only slide horizontally on the fixed shafts 62. The side of the limiting ring 69 away from the side plates 68 is provided with multiple grooves that are adapted to the limiting block 66. After the limiting block 66 and the groove of the limiting ring 69 are engaged, the threaded sleeve 65 can be restricted from rotating.
[0040] When not in use, the telescopic shaft of the electric telescopic rod 67 is in the retracted state, and the electric telescopic rod 67 causes the two side plates 68 to be on the outermost side, and the two threaded sleeves 65 respectively abut against the two side walls of the fixing ring 64.
[0041] Specifically, before aligning the main beam I-beam, the positions of the limiting block 66 and the side plates 68 need to be adjusted according to the dimensions of the main beam I-beam. Regarding the width of the main beam I-beam, if the width is wide, the operator can rotate the two threaded sleeves 65, causing them to rotate on the outer surface of the threaded post 63 and move away from each other. After adjusting the two threaded sleeves 65 to fit the main beam I-beam, the extension shaft of the electric telescopic rod 67 is controlled via the control panel 3. The electric telescopic rod 67 will then drive the two side plates 68 to slide on the fixed shaft 62. At this time, the two side plates... When the two side discs 68 approach each other, and the limiting ring 69 engages with the limiting block 66, the engagement of the limiting ring 69 and the limiting block 66 prevents the threaded sleeve 65 from rotating unexpectedly on the threaded post 63. The limiting block 66 is not fully inserted into the groove of the limiting ring 69; that is, the length of the limiting block 66 and the groove is relatively long. The limiting block 66 does not fully engage with the groove of the limiting ring 69, and it can still move horizontally a certain distance within the groove of the limiting ring 69. Regarding the height of the main beam I-beam, if the height of the main beam I-beam is high, then... The control panel 3 controls the simultaneous retraction of the telescopic shafts of the two hydraulic telescopic rods 4. These shafts drive the two lifting plates 5 upwards simultaneously. The two lifting plates 5 then drive the correction assembly located between them upwards, thus accommodating I-beams of different heights. By adjusting the threaded sleeve 65 and side plate 68 to fit I-beams of different sizes, precise fit with the flange and web contours of I-beams of different sizes is ensured, improving equipment utilization and achieving versatility for I-beams of different sizes. The threaded sleeve 65 or side plate 68 can also be adjusted... The adjustment is performed after wear. Specifically, the distance between the threaded sleeve 65 and the side plate 68 does not fit the flange of the I-beam. At this time, the distance between the threaded sleeve 65 and the side plate 68 can be adjusted. During the adjustment of the threaded sleeve 65 or the side plate 68, the limiting block 66 is further inserted into the groove of the limiting ring 69. At this time, the distance between the threaded sleeve 65 and the side plate 68 can be further reduced, which can effectively enable the threaded sleeve 65 and the side plate 68 to squeeze and correct the flange of the I-beam. Compared with the existing correction equipment that can only be replaced after wear, the adjustable design can improve the service life.
[0042] At this point, the two main beams (I-beams) need to be placed between the two sets of vertical beam plates 2 from one side of the correction base 1, referring to... Figure 1In the direction indicated, the main beam I-beam is placed between the two sets of vertical beam plates 2 from the left. During the placement of the main beam I-beam, it needs to be passed through the transmission module 8 on the right side first. At this time, the bottom of the main beam I-beam will contact the transmission roller at the bottom of the transmission module 8. The transmission roller at the top of the transmission module 8 rises and falls synchronously with the height of the lifting plate 5. At this time, the distance between the two transmission rollers of the transmission module 8 will be adapted to the main beam I-beam that needs to be corrected, so that the top of the main beam I-beam will contact the transmission roller at the top of the transmission module 8. The motor of the transmission module 8 is started by controlling the control panel 3. After the motor of the transmission module 8 starts, it will cause the transmission roller to drive the main beam I-beam. Moving to the right, the main beam I-beam will enter between the two correction components. At this time, the main beam I-beam can be squeezed and clamped by the two correction components. That is, the upper and lower surfaces of the I-beam will abut against the surfaces of the limiting rings 69 of the two correction components. At this time, the motor of the rotating cylinder 61 is started by the control panel 3. After the motor of the rotating cylinder 61 starts, it will drive the rotating cylinder 61 to rotate. The rotation of the rotating cylinder 61 will drive the fixed shaft 62 to rotate synchronously. With the synchronous rotation of the transmission roller of the transmission module 8, the main beam I-beam can move. With the help of the threaded sleeve 65 and the side plate 68, the main beam I-beam is squeezed, thereby achieving the effect of correcting the flange of the main beam I-beam.
[0043] like Figure 1 , Figures 7 to 10 As shown, the support assembly includes two base plates 71 fixedly connected to both sides of the correction base 1. Each base plate 71 has a sliding groove 72, and a movable seat 73 is slidably connected inside each of the two sliding grooves 72. Two sets of upper and lower rollers 74 are rotatably connected to the outer walls of each movable seat 73. Each set of rollers 74 consists of four rollers, which roll against the upper and lower surfaces of the base plate 71 respectively. A lifting sleeve 75 is fitted onto the outer surface of each movable seat 73, and a fixing frame 76 is fixedly connected to the top of each lifting sleeve 75. A threaded groove is formed in the middle of each movable seat 73, and a threaded groove is formed in the middle of each fixing frame 76 that connects to the movable seat 73. The threaded grooves correspond to the through holes, and the threaded grooves of the two movable seats 73 are threadedly connected to threaded rods 78. The top of the threaded rods 78 passes through the through hole of the fixed frame 76. The outer surface of the threaded rods 78 and the inner side wall of the through hole of the fixed frame 76 are rolled together by multiple balls 77 arranged in a ring array. The two threaded rods 78 are fixedly connected to a rotating frame 79 at one end of the two adjacent fixed frames 76. The two side walls of the two fixed frames 76 are provided with slots corresponding to the rotating frame 79, so that the rotating frame 79 can protrude from the fixed frame 76 through the slots of the fixed frame 76, making it convenient for the operator to rotate the rotating frame 79. A sliding frame 710 is slidably connected in each of the two fixed frames 76.
[0044] It should be noted that, referring to Figure 1As shown, one movable seat 73 is located at the end of the base plate 71 away from the correction base 1, and the other movable seat 73 is located at the end of the base plate 71 close to the correction base 1. The outer surface of the rotating frame 79 is provided with a rough texture.
[0045] Specifically, because the main beam I-beams that need to be corrected are deformed, they may bend in various ways, resulting in their ends not being on the same horizontal plane. When placing the main beam I-beams into the control panel 3, the ends of the main beam I-beams can be placed on a sliding bracket 710 away from the correction base 1, specifically the end of the main beam I-beam not placed inside the upright beam plate 2. To ensure stable and effective support for the main beam I-beams, the operator can push the rotating bracket 7 from the slot on the side of the fixed bracket 76. 9. Rotation of the rotating frame 79 causes the threaded rod 78 to rotate within the threaded groove of the movable seat 73. As the threaded rod 78 rotates in conjunction with the threaded groove of the movable seat 73, it spirals upwards. The ball bearings 77 ensure smooth rotation of the threaded rod 78. Furthermore, the spiraling upward movement of the threaded rod 78, via the ball bearings 77, causes the fixed frame 76 to move upwards synchronously. The fixed frame 76 then causes the lifting sleeve 75 to move upwards on the outer surface of the movable seat 73. The upward movement of the fixed frame 76 causes the sliding frame 710 to move upwards synchronously, thereby enabling the sliding frame 710 to... 10. The main beam I-beam is supported to a horizontal position, ensuring that it can enter the interior of the vertical beam plate 2 horizontally. Furthermore, when the main beam I-beam is moved by the transmission module 8 and the two correction components, the support of the main beam I-beam rests on the sliding frame 710, placing the sliding frame 710 under stress. The movement of the main beam I-beam causes the sliding frame 710 to move synchronously. The sliding frame 710, through the fixed frame 76, causes the lifting sleeve 75 to drive the moving seat 73 to slide inside the slide groove 72. When the moving seat 73 moves... The rollers 74 roll on the upper and lower surfaces of the base plate 71, ensuring the smooth and stable movement of the movable seat 73. The sliding frame 710 provides real-time support for the main beam I-beam, preventing the end of the main beam I-beam away from the correction base 1 from drooping during the correction process. This further ensures that the main beam I-beam enters the interior of the upright beam plate 2 in a horizontal posture for correction, avoiding tilting and causing uneven stress on the correction equipment, and reducing the uneven load of the main beam I-beam on the correction equipment.
[0046] Furthermore, when supporting the main beam I-beam, the operator can also push the movable seat 73 to move horizontally on the base plate 71 through the slide groove 72, so that the sliding frame 710 can move closer to or further away from the main beam I-beam, thereby adapting to the use of supporting main beam I-beams of different sizes.
[0047] like Figure 1 , Figures 7 to 9As shown, the support assembly also includes two upright plates 711 fixedly connected to the top of the two sliding frames 710. An electric cylinder 712 is fixedly connected to the side of the two upright plates 711 that is far apart from each other. The telescopic shafts of the two electric cylinders 712 pass through the adjacent upright plates 711 respectively. A clamping plate 713 is fixedly connected to the end of the telescopic shafts of the two electric cylinders 712 that is close to each other.
[0048] It should be noted that the two clamping plates 713 have a rough texture on the side that is close to each other, which is used to stably clamp the I-beam of the main beam.
[0049] Specifically, during the alignment of the main beam I-beam, due to the compression effect, the uncompressed end of the main beam I-beam may sway as stress is released. To address this, after the end of the main beam I-beam is placed on the sliding frame 710, the extension shafts of the two electric cylinders 712 are controlled via the control panel 3. The extension shafts of the electric cylinders 712 will cause the two clamping plates 713 to move closer together. The rough-textured side of the two clamping plates 713 will clamp the main beam I-beam. The clamping plates 713 then... After clamping, if there is horizontal sway, the main beam I-beam will cause the electric cylinder 712 to drive the vertical plate 711 to swing synchronously through the clamping plate 713. The vertical plate 711 will drive the sliding frame 710 to slide horizontally on the fixed frame 76. By restricting the sliding frame 710 through the fixed frame 76, the sway of the main beam I-beam can be limited, avoiding large-amplitude sway of the main beam I-beam. This reduces the damage to surrounding personnel and equipment caused by the sway of the main beam I-beam, ensuring the safety of the main beam I-beam correction process.
[0050] It should be noted that, referring to Figure 1 In the direction of the correction, the end of the main beam I-beam will move to the right. At this time, the corrected end will rest on the sliding frame 710 on the right. Alternatively, the end of the main beam I-beam can be clamped by the clamping plate 713 on the right support component. Thus, the corrected end of the main beam I-beam will also be supported, which can also prevent the main beam I-beam from sag due to gravity after correction, ensuring the stability of the shape of the main beam I-beam after correction and avoiding bending.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
