[0002] During the expansion of steel pipes, especially for pipes with large diameters, a steel pipe rotating and traversing carriage is used to move and rotate the pipe 180 degrees to expand both ends. When the carriage rotates the pipe 180 degrees, the rotating support inevitably vibrates due to inertia or friction when the rotation stops. This vibration occurs every time the rotation stops, negatively impacting the stability of the connection between the rotating support and the steel pipe, as well as the stability of the connection between the rotating support and the traversing support over time.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 To be continued Figure 5This embodiment provides a steel pipe rotating and traversing vehicle, including a traversing support 1, a rotating support 2 disposed above the traversing support 1, a steel pipe lifting device 3 disposed on the rotating support 2, a rotating device 4 disposed between the traversing support 1 and the rotating support 2 for driving the rotating support 2 to rotate relative to the traversing support 1, and a shock-absorbing device 9 disposed between the traversing support 1 and the rotating support 2; the shock-absorbing device 9 includes a first shock-absorbing block 91 disposed on the traversing support 1 and a first shock-absorbing module 92 disposed on the rotating support 2. The first shock-absorbing block 91 and the first shock-absorbing module 92 are made of shock-absorbing and buffering materials such as rubber, polyurethane, or plastic. The steel pipe rotating and transverse moving vehicle provided in this embodiment has a first shock-absorbing module 92 on the rotating support 2 that cooperates with the first shock-absorbing block 91 on the transverse moving support 1 when the rotating support 2 rotates 180 degrees in the forward direction. This effectively reduces the vibration level of the rotating support 2, which is beneficial to ensuring the stability of the connection structure between the rotating support 2 and the steel pipe, as well as the stability of the connection structure between the rotating support 2 and the transverse moving support 1.

[0027] The first shock-absorbing block 91 is provided with a first shock-absorbing baffle 911 coplanar with the rotation axis of the rotating bracket 2, and the first shock-absorbing module 92 is provided with a first shock-absorbing inclined surface 921 coplanar with the rotation axis of the rotating bracket 2. When the rotating bracket 2 rotates 180 degrees relative to the transverse support 1, the first shock-absorbing baffle 911 and the first shock-absorbing inclined surface 921 are in contact. Since the first shock-absorbing baffle 911 and the rotation axis of the rotating bracket 2 are coplanar, and the first shock-absorbing inclined surface 921 is also coplanar with the rotation axis of the rotating bracket 2, when the rotating bracket 2 rotates relative to the transverse support 1 until the first shock-absorbing block 91 and the first shock-absorbing module 92 cooperate, the first shock-absorbing baffle 911 and the first shock-absorbing inclined surface 921 can fit together, achieving a better shock absorption and buffering effect.

[0028] Furthermore, the vibration damping device 9 also includes a second vibration damping block 93 disposed on the transverse support 1 and a second vibration damping module 94 disposed on the rotating support 2. The second vibration damping block 93 and the second vibration damping module 94 are made of vibration damping and cushioning materials such as rubber, polyurethane, or plastic. On the one hand, when the rotating support 2 stops rotating in the forward direction relative to the transverse support 1, the first vibration damping block 91 and the first vibration damping module 92 can cooperate to achieve buffering and vibration damping. On the other hand, when the rotating support 2 stops rotating in the reverse direction relative to the transverse support 1, the second vibration damping block 93 and the second vibration damping module 94 can cooperate to achieve buffering and vibration damping, which helps to reduce the degree of vibration and ensure the stability of the connection structure.

[0029] The second shock-absorbing block 93 is provided with a second shock-absorbing baffle 931 coplanar with the rotation axis of the rotating bracket 2, and the second shock-absorbing module 94 is provided with a second shock-absorbing inclined surface 941 coplanar with the rotation axis of the rotating bracket 2. When the rotating bracket 2 rotates 180 degrees in the opposite direction to the transverse support 1, the second shock-absorbing baffle 931 and the second shock-absorbing inclined surface 941 are in contact. Since the second shock-absorbing baffle 931 and the rotation axis of the rotating bracket 2 are coplanar, and the second shock-absorbing inclined surface 941 are also coplanar with the rotation axis of the rotating bracket 2, when the rotating bracket 2 rotates relative to the transverse support 1 until the second shock-absorbing block 93 and the second shock-absorbing module 94 cooperate, the second shock-absorbing baffle 931 and the second shock-absorbing inclined surface 941 can fit together, achieving a better shock absorption and buffering effect.

[0030] Furthermore, the first shock-absorbing block 91 and the second shock-absorbing block 93 are both located below the rotating bracket 2, and there is a gap between them. This effectively avoids interference between the rotating bracket 2 and the first shock-absorbing block 91 and the second shock-absorbing block 93, ensuring that the rotating bracket 2 can rotate smoothly relative to the transverse support 1.

[0031] Furthermore, the upper end of the first damping module 92 is connected to the rotating bracket 2, and the lower end of the first damping module 92 is provided with a first damping connecting cavity 922, on which the first damping inclined surface 921 is disposed; the upper end of the second damping module 94 is connected to the rotating bracket 2, and the lower end of the second damping module 94 is provided with a second damping connecting cavity 942, on which the second damping inclined surface 941 is disposed. When the first damping block 91 cooperates with the first damping module 92, the first damping baffle 911 first enters the first damping connecting cavity 922 and then fits against the first damping inclined surface 921. The first damping connecting cavity 922 has a limiting and guiding function for the first damping baffle 911, which is beneficial to the cooperation between the first damping baffle 911 and the first damping inclined surface 921. Similarly, when the second damping block 93 is engaged with the second damping module 94, the second damping baffle 931 first enters the second damping connecting cavity 942 and then fits against the second damping inclined surface 941. The second damping connecting cavity 942 has a limiting and guiding function for the second damping baffle 931, which is beneficial to the engagement of the second damping baffle 931 with the second damping inclined surface 941.

[0032] Furthermore, both the forward and backward ends of the transverse support 1 are equipped with polyurethane buffers 11. The polyurethane buffer 11 is a device that uses the special microporous bubble structure of polyurethane material to absorb energy and buffer. Specifically, when the polyurethane buffer 11 is subjected to impact, its internal microporous bubble structure absorbs energy, thereby playing a buffering role.

[0033] Furthermore, the rotating device 4 includes a large gear 41 mounted on the transverse support 1, a small gear 42 meshing with the large gear 41, and a rotary drive motor 43 mounted on the rotating support 2. The output end of the rotary drive motor 43 is connected to the small gear 42 to drive the small gear 42 to rotate. The rotating device 4 also includes casters 44 mounted on the rotating support 2 and an annular slide rail 45 mounted on the transverse support 1. When the rotating support 2 rotates relative to the transverse support 1, the casters 44 move along the annular slide rail 45. When it is necessary to rotate the steel pipe, the rotary drive motor 43 drives the small gear 42 to rotate, thereby causing the small gear 42 to move circumferentially along the large gear 41, which in turn drives the rotating support 2 to rotate relative to the transverse support 1. At the same time, the casters 44 on the rotating support 44 move along the annular slide rail 45. On the one hand, the casters 44 can provide stable support for the rotating support 2; on the other hand, the rolling friction between the casters 44 and the annular slide rail 45 makes the rotation of the rotating support 2 smoother.

[0034] Furthermore, a traveling device 5 is provided below the transverse support 1. The traveling device 5 includes two parallel guide rails 51, a traveling wheel set 52 movably mounted on the guide rails 51, and a traveling drive mechanism 53 for driving the traveling wheel set 52 to move along the guide rails 51. The traveling wheel set 52 includes a driving wheel 521 and a driven wheel 522 spaced apart along the extension direction of the guide rails 51. The driving wheel 521 is connected to the traveling drive mechanism 53. The traveling drive mechanism 53 is a traveling drive motor. The two corresponding driving wheels 521 on the two parallel guide rails 51 are connected to the traveling drive motor through a rotating shaft and a coupling. One traveling drive motor can drive the two driving wheels 521 to rotate synchronously, thereby conveniently and efficiently driving the traveling wheel set 52 to move along the guide rails 51.

[0035] Furthermore, an anti-tipping device 6 is provided below the transverse support 1. One end of the anti-tipping device 6 is connected to the transverse support 1, and the other end is provided to clamp and cooperate with the guide rail 51. Since the transverse support 1 is clamped and cooperated with the guide rail 51 through the anti-tipping device 6, when the steel pipe rotating transverse vehicle is subjected to uneven force, the transverse support 1 and the guide rail 51 can still maintain a stable connection, and the traveling wheel set 52 and the guide rail 51 can still maintain a stable connection, thereby effectively preventing the occurrence of overturning.

[0036] Specifically, the guide rail 51 includes a guide portion 511, a mounting portion 512 disposed below the guide portion 511, and a connecting portion 513 connecting the guide portion 511 and the mounting portion 512. The width of the guide portion 511 is greater than the width of the connecting portion 513. The anti-tipping device 6 is provided with a connecting groove 63 that mates with the guide portion 511. The anti-tipping device 6 includes a connecting module 61 connected to the transverse support 1, and two opposing clamping arms 62 disposed at the lower end of the connecting module 61. The connecting groove 63 is formed between the two clamping arms 62. The clamping arm 62 includes a first clamping plate 621 disposed beside the guide portion 511 and a second clamping plate 622 disposed below the guide portion 511. The clamping arm 62 is detachably connected to the connecting module 61 by bolts. The clamping arms 62 on both sides of the connecting module 61 simultaneously limit the lateral movement of the guide part 511 by the first clamping plate 621 and limit the downward movement of the guide part 511 by the second clamping plate 622. This effectively prevents the guide part 511 from disengaging from the side or from the bottom of the connecting groove 63, so that the transverse support 1 and the guide rail 51 can still maintain a stable connection when encountering uneven force on the steel pipe rotating transverse vehicle.

[0037] Furthermore, the steel pipe lifting device 3 includes a lifting module 31, a hydraulic drive mechanism 32 for driving the lifting module 31 to rise and fall, and lifting guide mechanisms 33 located on both sides of the hydraulic drive mechanism 32. The lifting guide mechanism 33 includes a sleeve and a guide column located inside the sleeve. The sleeve is fixedly connected to the rotating bracket 2, and the guide column is connected to the lifting module 31. When the steel pipe is moved by the rotating transverse trolley, the steel pipe is placed on the lifting module 31. The hydraulic drive mechanism 32 can drive the lifting module 31 to rise and fall, thereby driving the steel pipe to rise and fall. The lifting guide mechanism 33 provides guidance for the lifting module 31 to rise and fall, which is conducive to smooth and stable lifting.

[0038] Furthermore, two steel pipe lifting devices 3 are spaced apart on the rotating support 2 along its length. A steel pipe rotating roller 21 is provided between the two steel pipe lifting devices 3, and the axis of rotation of the steel pipe rotating roller 21 is perpendicular to the length of the rotating support 2. The steel pipe rotating roller 21 can drive the steel pipe to move between the two steel pipe lifting devices 3 to adjust the relative position of the steel pipe on the two steel pipe lifting devices 3 to a predetermined position, so that the steel pipe is kept balanced on the two steel pipe lifting devices 3 and uneven force is avoided in the steel pipe rotating and traversing vehicle.

[0039] Furthermore, the rotating support 2 is equipped with a tie beam device 7, which includes a first outer support 71, a first inner support 72, a second inner support 73, and a second outer support 74 arranged sequentially at intervals along the length of the rotating support 2. A main beam 75 is provided between the first inner support 72 and the second inner support 73. Tie beams 76 are hinged between the first outer support 71 and the first inner support 72, and between the second outer support 74 and the second inner support 73. The tie beam device 7 can provide tension at both ends of the rotating support 2 along its length, making the overall structure of the rotating support 2 more stable.

[0040] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or angular relationship based on the orientation or angular relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
