Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated steel pipe transportation, and in particular to a steel pipe loading device and a loading method. Background Art

[0002] With the rapid development of social economy and the increasing number of various engineering projects, higher requirements are placed on the efficiency, quality and reliability of steel pipe engineering. In traditional steel pipe construction, a large amount of steel pipe production work is often required on site, which is not only time-consuming, but also restricted by many factors of the on-site environment, and is prone to problems such as unstable quality. Prefabricated steel pipe technology came into being. Through centralized production in factories or special prefabrication sites, it can effectively overcome the limitations of on-site construction. Prefabricated steel pipes can be customized and produced according to different engineering needs to meet various complex steel pipe layout and functional requirements.

[0003] When transporting prefabricated steel pipes, the stability of the pipe wall clamping is crucial. If the clamping is unstable, the steel pipe will shake, shift or even fall off during transportation, which will not only cause damage to the steel pipe itself, such as scratches and collisions that cause the pipe wall to dent or crack, affecting its subsequent performance and safety, but also trigger a series of chain reactions. For example, it will endanger the safety of transportation equipment and personnel, cause transportation interruptions, and delay project progress or production plans.

[0004] This unstable clamping of the pipe wall is caused by many factors. On the one hand, the unreasonable design of the clamping device is one of the important reasons. If its structure cannot adapt well to steel pipes of different diameters and materials, or lacks sufficient tightening force and adjustability, it is easy to have loose clamping problems. On the other hand, the complexity of the transportation environment will also have an impact, such as road bumps and vibrations, which can cause the originally tight clamping to loosen.

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The steel pipe loading device and loading method according to the embodiment of the present invention are described below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the steel pipe loading device provided by the embodiment of the present invention includes a bottom plate 1, a bottom supporting mechanism 2 and a side wall clamping mechanism 3.

[0026] The bottom supporting mechanism 2 is used to support the bottom of the steel pipe. The bottom supporting mechanism 2 includes a cross beam 22, a pull-out plate 21 and a bottom supporting block 23, wherein the cross beam 22 is arranged on the upper surface of the bottom plate 1, the bottom supporting block 23 is arranged in the middle position of the upper surface of the cross beam 22, and two pull-out plates 21 are arranged, respectively arranged at the two ends of the cross beam 22.

[0027] The side wall clamping mechanism 3 is used to clamp the two sides of the steel pipe, and the side wall clamping mechanism 3 includes a clamp assembly 31, a side wall push rod 33 and a clamp arm 35, wherein the clamp arm 35 is arranged at the end of the pull-out plate 21 away from the cross beam 22, the side wall push rod 33 is hingedly arranged at the top of the clamp arm 35, and the clamp assembly 31 is arranged at the end of the power shaft of the side wall push rod 33 and the top of the clamp arm 35.

[0028] Specifically, when loading the steel pipe, first hang the steel pipe horizontally on the crossbeam 22, place the bottom of the steel pipe on the bottom support block 23, and then adjust the distance between the two pull-out plates 21 until the clamp assembly 31 at the top of the clamp arm 35 contacts both sides of the steel pipe and the two pull-out plates 21 stop approaching.

[0029] Then, the angle of the side wall push rod 33 is rotated and adjusted, and the supporting length of the side wall push rod 33 is adjusted until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe, and the side wall push rod 33 stops moving.

[0030] In this way, the bottom of the steel pipe can be clamped by the bottom support block 23, the two sides of the steel pipe can be clamped by the clamp assembly 31 on the clamp arm 35 to center the steel pipe, and the upper part of the horizontal diameter of the pipe wall can be clamped by the side wall push rod 33 to prevent the steel pipe from jumping up and down and rolling down. In addition, the spacing between the clamp arms 35 and the spacing between the side wall push rods 33 can be adjusted to adapt to steel pipes of different diameters and stably clamp the pipe wall.

[0031] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the side wall push rod 33 is an arc-shaped structure, and an angle adjustment push rod 34 for adjusting the clamping angle of the side wall push rod 33 is provided between the side wall push rod 33 and the clamp arm 35. The power shaft of the side wall push rod 33 is connected to the clamp assembly 31 by setting a spring hinge 32.

[0032] Specifically, the arc-shaped side wall push rod 33 can adapt to the close arc-shaped pipe wall, reduce the overflow space of the side wall push rod 33 relative to the pipe wall, and make the loading space more compact; on the other hand, the arc-shaped side wall push rod 33 can extend a wider distance to the left and right sides through the angle adjustment push rod 34, which is suitable for clamping steel pipes of different diameters; the side wall push rod 33 itself can shrink, so it can cover a larger upper and lower distance, which is used to adapt to the position above the horizontal diameter of the clamping pipe wall to prevent the steel pipe from jumping up and down and rolling down.

[0033] In one embodiment of the present invention, Figure 4 As shown, the clamp assembly 31 includes a clamping plate 311, a clamping rubber claw 312 and a contact sensor 313. The clamping plate 311 is hinged to the end of the power shaft of the side wall push rod 33 and the top end of the clamping arm 35 respectively. The clamping rubber claw 312 is arranged on the clamping surface of the clamping plate 311, and the contact sensor 313 is arranged at the bottom of the clamping rubber claw 312. The interior of the clamping rubber claw 312 is a hollow structure.

[0034] Specifically, after the clamping rubber claw 312 contacts the surface of the steel pipe, the clamping plate 311 continues to press tightly to cause the clamping rubber claw 312 to deform. When the contact sensor 313 at the bottom of the clamping rubber claw 312 is squeezed, the contact sensor 313 transmits a contact signal to the controller; at this time, when the contact sensor 313 on the clamping arm 35 transmits a contact signal, the controller controls the pull-out plate push rod 222 to stop moving; when the contact sensor 313 on the side wall push rod 33 transmits a contact signal, the controller controls the side wall push rod 33 to stop moving.

[0035] The clamping rubber claws 312 can provide an elastic support effect to the tube wall through self-compression, thereby preventing the tube wall from being damaged by hard contact with the clamp assembly 31, and also preventing the occurrence of a frame phenomenon between the tube wall and the clamp assembly 31, making the tube wall clamping more close and stable.

[0036] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, a pull-out plate push rod 222 is arranged between the cross beam 22 and the pull-out plate 21, guide rails 221 for slidingly limiting the pull-out plate 21 are arranged on both sides of the cross beam 22, and pull-out plate sliders 211 are arranged at both ends of the pull-out plate 21. The pull-out plate 21 is slidably connected to the vertical side of the clamping arm 35 through the pull-out plate slider 211, and the bottom of the clamping arm 35 is slidably connected to the bottom plate 1. A supporting push rod 24 is arranged at the bottom of the cross beam 22, and the upper surface of the bottom support block 23 is an inverted V-shaped structure, which limits and supports the bottom of the steel pipe during the initial hanging process of the steel pipe.

[0037] Specifically, refer to Figure 7 When the radius of the steel pipe is large, the height of the supporting push rod 24 is lowered, driving the position of the crossbeam 22 to drop, lowering the height of the steel pipe, and then shortening the length of the pull-out plate push rod 222, driving the two pull-out plates 21 closer to each other, and then driving the two clamping arms 35 closer to each other, until the clamp assembly 31 at the top of the two clamping arms 35 contacts both sides of the steel pipe, and the pull-out plate push rod 222 stops moving.

[0038] In one embodiment of the present invention, buffer bases 11 are respectively provided at both ends of the bottom of the bottom plate 1. The buffering direction of the buffer base 11 is a vertical direction, and is used to buffer the up and down bumping force of the steel pipe.

[0039] Then adjust the length of the angle adjustment push rod 34 and the length of the arc-shaped side wall push rod 33 until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe, and the angle adjustment push rod 34 and the side wall push rod 33 stop moving.

[0040] Reference Figure 8 When the radius of the steel pipe is small, the height of the supporting push rod 24 is increased, driving the position of the cross beam 22 to rise, thereby increasing the height of the steel pipe, and then shortening the length of the pull-out plate push rod 222, driving the two pull-out plates 21 and the clamp arms 35 to approach each other, until the clamp assemblies 31 at the top of the two clamp arms 35 are in contact with both sides of the steel pipe, and then the pull-out plate push rod 222 stops moving.

[0041] Then adjust the length of the angle adjustment push rod 34 and the length of the arc-shaped side wall push rod 33 until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe. The angle adjustment push rod 34 and the side wall push rod 33 stop moving to adapt to clamping steel pipes of different diameters so that the pipe wall can be clamped up and down and left and right to prevent the steel pipe from jumping up and down and rolling down.

[0042] In order to clearly explain the above embodiments, refer to Figure 1-8 The specific working principle of the steel pipe loading device of the present invention is as follows: When loading the steel pipe, first hang the steel pipe horizontally on the beam 22, and place the bottom of the steel pipe on the bottom support block 23 of the V-shaped structure to fix the bottom of the steel pipe. Then shorten the length of the pull-out plate push rod 222 to drive the two clamping arms 35 closer to each other until the clamp assembly 31 at the top of the clamping arm 35 contacts both sides of the steel pipe, and then the pull-out plate push rod 222 stops moving.

[0043] During the clamping process of the clamp assembly 31, after the clamping rubber claw 312 contacts the surface of the steel pipe, the clamping plate 311 continues to press to cause the clamping rubber claw 312 to deform. When the contact sensor 313 at the bottom of the clamping rubber claw 312 is squeezed, the contact sensor 313 transmits a contact signal to the controller. When the contact sensor 313 on the clamping arm 35 transmits a contact signal, the controller controls the pull-out plate push rod 222 to stop moving, so that the pipe wall and the clamping arm 35 are clamped together.

[0044] Then adjust the length of the angle adjustment push rod 34 and the length of the arc-shaped side wall push rod 33 until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe. The angle adjustment push rod 34 and the side wall push rod 33 stop moving, so that the pipe wall can be clamped up and down, left and right, to prevent the steel pipe from jumping up and down and rolling down.

[0045] When the radius of the steel pipe is large, the supporting push rod 24 is shortened downward, reducing the height of the supporting push rod 24, driving the position of the crossbeam 22 to drop, thereby lowering the height of the steel pipe, and then shortening the length of the pull-out plate push rod 222, driving the two pull-out plates 21 closer to each other, and then driving the two clamping arms 35 closer to each other, until the clamp assembly 31 at the top of the two clamping arms 35 contacts both sides of the steel pipe, and the pull-out plate push rod 222 stops moving.

[0046] Then adjust the length of the angle adjustment push rod 34 and the length of the arc-shaped side wall push rod 33 until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe, and the angle adjustment push rod 34 and the side wall push rod 33 stop moving.

[0047] When the radius of the steel pipe is small, the height of the supporting push rod 24 is increased, driving the position of the cross beam 22 to rise, thereby increasing the height of the steel pipe, and then shortening the length of the pull-out plate push rod 222 to drive the two pull-out plates 21 and the clamping arms 35 to approach each other until the clamp assembly 31 at the top of the two clamping arms 35 contacts both sides of the steel pipe, and then the pull-out plate push rod 222 stops moving, ensuring that the pipe wall is clamped at the upper, lower, left and right positions to prevent the steel pipe from slipping and jumping up and down.

[0048] In addition, the present invention provides a steel pipe loading method, comprising the following steps: S1. Hang the steel pipe horizontally on the beam 22, and place the bottom of the steel pipe on the bottom support block 23 of the V-shaped structure; S2, shorten the length of the pull-out plate push rod 222 until the clamp assembly 31 at the top of the clamp arm 35 contacts both sides of the steel pipe, and the pull-out plate push rod 222 stops moving; S21, after the clamping rubber claw 312 contacts the surface of the steel pipe, the clamping plate 311 continues to press and deform the clamping rubber claw 312, and when the contact sensor 313 at the bottom of the clamping rubber claw 312 is squeezed, the contact sensor 313 transmits a contact signal to the controller, and when the contact sensor 313 on the clamping arm 35 transmits a contact signal, the controller controls the pull-out plate push rod 222 to stop moving; S3, then adjusting the length of the angle adjustment push rod 34 and the length of the arc-shaped side wall push rod 33 until the clamp assembly 31 on the top of the side wall push rod 33 is clamped above the horizontal diameter of the steel pipe, and the angle adjustment push rod 34 and the side wall push rod 33 stop moving; S4, when the radius of the steel pipe is large, lower the height of the supporting push rod 24, lower the height of the steel pipe, and repeat steps S2 and S3; S5. When the radius of the steel pipe is small, raise the height of the supporting push rod 24, raise the height of the steel pipe, and repeat steps S2 and S3.

[0049] In summary, the steel pipe loading device of the present application can clamp the bottom of the steel pipe through the bottom support block 23, clamp both sides of the steel pipe through the clamp assembly 31 on the clamp arm 35 to center the steel pipe, and clamp the upper horizontal diameter of the pipe wall through the side wall push rod 33 to prevent the steel pipe from jumping up and down and rolling down. In addition, the spacing between the clamp arms 35 and the spacing between the side wall push rods 33 can be adjusted to adapt to steel pipes of different diameters and stably clamp the pipe wall.
