[0002] In the existing electromechanical and municipal engineering construction, large-diameter steel pipes are usually transported once by forklifts or cranes, and collected or stacked in a safe location after arriving at the work site. However, the work site is usually far away from the steel pipe stacking site, and the steel pipes need to be manually transported to the work site for a second time.

[0003] However, during the secondary handling of steel pipes, the steel pipes may be damaged due to their own specifications, size, terrain, manpower limitations, etc. In addition, in the prior art, the secondary handling of steel pipes is often carried out by manual handling or rolling on rollers, which is a process with certain risks. For example, due to the heavy weight of the steel pipes, the handling personnel may be exhausted and cause safety accidents, or due to the size of the steel pipes, they may rub against each other during the handling process, making it difficult to protect the galvanized layer or anti-rust paint on the surface of the steel pipes.

[0034] Combination Figure 1-Figure 8 As shown, the steel pipe transportation device in the present application can be used not only in the transportation operation scenarios of steel pipe fittings 1 in electromechanical or municipal construction, but also in the transportation operation scenarios of long material transportation in different industries.

[0035] A steel pipe transportation device includes a steel pipe fitting 1 placed horizontally on a horizontal plane, and also includes a receiving rod 10, a supporting rod 20, a fixing rod 30, a push rod 40, and a rotating wheel 50; the receiving rod 10 is horizontally set off the ground, and the rotating wheels 50 are respectively fixedly set at both ends of the receiving rod 10, so that the receiving rod 10 can carry the steel pipe fitting 1 and move it from a stacking point to an operation point. One end of the supporting rod 20 is fixedly connected to the rod body of the receiving rod 10 to share the force of the steel pipe fitting 1 acting on the receiving rod 10. The other end of the supporting rod 20 is movably connected to the bottom of the fixing rod 30, so that the fixing rod 30 can be rotated relative to the supporting rod 20 to adapt to different postures of the steel pipe fitting 1 when stacked, so that the staff can place the steel pipe fitting 1 on the fixing rod 30. The middle part of the fixing rod 30 can accommodate the steel pipe fitting 1, so as to facilitate the handling operation of the steel pipe fitting 1. One end of the push rod 40 is fixedly arranged on the rod body of the support rod 20. The staff can hold the push rod 40 to push the support rod 20 to drive the rotating wheel 50 of the receiving rod 10 to rotate, so as to realize the handling operation of the steel pipe fitting 1, improve the handling efficiency and save manpower and material resources. The fixed end of the clamping member 60 is fixedly connected to one end of the fixed rod 30, and the movable end of the clamping member 60 passes through the other end of the fixed rod 30 and is slidably connected thereto to form a limit fit. The inner side surface of the clamping member 60 is in contact with the circumference of the steel pipe fitting 1.

[0036] The clamping member 60 in the present application can be a square rod or a curved plate. The shape of the clamping member 60 is not limited in the present application. In order to highlight the advantages of the embodiments of the present application, the clamping member 60 of the present application adopts a curved plate. One end of the clamping member 60 is fixed on the fixed rod 30 to ensure the stable connection between the clamping member and the fixed rod 30, and the other end of the clamping member 60, i.e., the movable end, is movably connected to the fixed rod 30, so that the inner side surface of the clamping member 60 fits on the peripheral surface of the steel pipe fitting 1, thereby constraining the steel pipe fitting 1 to the bottom of the valley of the fixed rod 30, avoiding the steel pipe fitting 1 from bouncing in the Y direction due to the uneven road surface during transportation, so as to ensure the integrity of the surface of the steel pipe fitting 1. In addition, the clamping member 60 in the present application can be an elastic material or a hard material. The material of the clamping member 60 is not limited in the present application. In order to highlight the advantages of the present application, the clamping member 60 in the present application is made of elastic material. The purpose of this setting is to be able to use its own elastic force to constrain the valley of the fixed rod 60, thereby avoiding stress collision between the clamping member 60 made of rigid material and the rigid circumferential surface of the steel pipe fitting 1, thereby ensuring the integrity of the steel pipe fitting 1.

[0037] Through holes 31 for the clamping member to pass through are provided at both ends of the fixing rod 30, and the through holes 31 are slidably connected to the clamping member 60. Under plumb projection, the two through holes 31 are arranged in a high and low position staggered arrangement, and a check block 32 extends from the inner wall of the through hole 31 in the high position along its radial direction, and a check plate 321 extends from the top of the check block 32 along the axial direction of the through hole.

[0038] In the above scheme, the through hole is provided to facilitate the moving end of the clamping member to pass through the fixed rod, and the check block 32 is provided to cooperate with the moving end of the clamping member 60 to limit the displacement of the clamping member 60 in the X direction, thereby ensuring the stable connection between the moving end of the clamping member 60 and the fixed rod 30. The check plate 321 is provided to limit the displacement of the clamping member 60 in the Y direction.

[0039] A slide groove 61 is provided on one side of the clamping member 60 close to the steel pipe. The width of the slide groove 61 is greater than the width of the check block. A limit block 62 extends from the bottom of the slide groove 61 to the groove opening. The inner end of the limit block 62 abuts against the check plate 321.

[0040] In the above scheme, the slide groove 61 is provided to constrain the check block 32 in the groove cavity to prevent the check block 32 from being separated from the clamping member 60. The inner end surface of the limit block 62 abuts against the check plate 321, thereby limiting the displacement of the clamping member 60 in the through hole 31 of the fixing rod 30 in the X direction.

[0041] The support rod 20 is fixed with a bearing 60 for the fixed rod 30 to rotate around the axial length direction of the support rod 20, and the axis of the bearing 60 is coaxial with the rod center of the support rod 20. This is to facilitate the posture of the steel pipe fittings 1 when they are stacked. The transporter can adjust the angle between the end face of the fixed rod 30 and the surface of the steel pipe fittings 1, and then directly roll the steel pipe fittings 1 into the airspace 301 of the fixed rod 30, and then transport the steel pipe fittings 1 by pushing and pulling. This process not only does not require the staff to lift the steel pipe fittings 1 to avoid safety accidents due to exhaustion, but also improves the efficiency of secondary transportation of steel pipes.

[0042] The fixing rod 30 in the present application is used to constrain the displacement path of the steel pipe fitting 1 in the X direction. The cross-sectional profile of the fixing rod 30 is U-shaped, C-shaped or V-shaped, so that the transport personnel can use the appropriate fixing rod 30 to deal with different transport objects. The cross-sectional profile of the fixing rod 30 in the present application is U-shaped to ensure that the outer wall of the fixing rod 30 is in good contact with the wall of the steel pipe fitting 1, so that the steel pipe fitting 1 does not swing back and forth in the airspace 301 of the fixing rod 30. A smooth protective pad 33 is attached to the contact surface between the rod body of the fixing rod 30 and the steel pipe fitting 1. The provision of the protective pad 33 can reduce the friction between the surface of the steel pipe fitting 1 and the outer side of the fixing rod 30, and effectively ensure the integrity of the surface of the steel pipe fitting 1.

[0043] In order to facilitate the handling personnel to push and pull the steel pipe 1 with the push rod 40 without effort, the push rod 40 is in an S-shape as a whole. The shape of the push rod is not limited in this application. In order to highlight the beneficial effects of this application, the push rod in this application is in an S-shape as a whole. One end of the push rod 40 is fixedly arranged on the outer wall of the support rod 20 away from the bearing 60, and the other end thereof is suspended.

[0044] The rod body of the receiving rod 10 has a reinforcing rib 80 extending from its outer surface along its radial direction, and the other end of the reinforcing rib 80 is fixedly connected to the outer wall of the support rod 20 away from the bearing 60. The provision of the reinforcing rib 80 effectively improves the modal strength of the steel pipe transportation device in the present application, avoids the fracture of the receiving rod 10 during the steel pipe handling operation, and causes the steel pipe to tip over, thereby reducing the damage rate of the surface of the steel pipe fitting 1. In addition, the reinforcing rib 80 connects the support rod 20 and the receiving rod 10 together, and shares the force generated by the steel component for the receiving rod 10, so as to improve the service life of the steel pipe transportation device.

[0045] In order to facilitate the handling personnel to control the push rod 40 to change the rotation path of the rotating wheels 50 at both ends of the receiving rod 10, the suspended end of the push rod 40 is extended along its radial direction to be used as a handheld cross bar 41, and an anti-slip sleeve 42 is attached to the rod body of the cross bar 41. The provision of the anti-slip sleeve 42 can make the handling personnel hold the cross bar 41 and push and pull the steel pipe 1 more firmly, avoiding safety accidents caused by the handling personnel losing strength due to sweat or water stains.

[0046] A shock-absorbing pad 51 is attached to the circumference of the rotating wheel 50. The setting of the shock-absorbing pad 51 can reduce the bouncing or vibration of the steel pipe 1 due to the uneven road surface during the transportation process of the steel pipe 1, thereby ensuring the integrity of the surface of the steel pipe 1. The edge of the shock-absorbing pad 51 is flush with the rim of the rotating wheel 50, making the appearance of the steel pipe handling device in the present application more beautiful.

[0047] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
