Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to a steel pipe stacking device. Background Technology

[0002] The individual steel pipes produced in the pipe manufacturing workshop need to be stacked and tied with packing straps to form multiple steel pipes into a whole, so as to facilitate hoisting and transportation.

[0003] The common stacking method involves construction workers placing steel pipes into a stacking frame via a conveyor or manually. The stacking frame consists of multiple steel plates forming a hexagonal cavity. After entering the stacking frame, the steel pipes are neatly stacked row by row from bottom to top. The steel pipes are constrained by the cavity to form a group of steel pipes with a hexagonal cross-section. The group of steel pipes is then packaged with strapping and transported out.

[0004] Because the stacking rack is constructed from multiple steel plates forming a hexagonal cavity, with the plates fixed together by bolts, the bolts need to be removed before transporting bundled steel pipes, leaving the stacking rack open to create space for subsequent operations. However, the installation and disassembly processes affect overall production efficiency and are labor-intensive. Therefore, a steel pipe stacking device is needed to improve the production efficiency of the entire stacking and transportation process. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a steel pipe stacking device.

[0006] The steel pipe stacking device provided by this utility model adopts the following technical solution:

[0007] A steel pipe stacking device is installed between two adjacent roller conveyor lines. The device includes a bracket for supporting steel pipes, a limiting mechanism for controlling the stacking position of steel pipes, a lifting mechanism for controlling the up and down movement of the supporting surface of the bracket, and a pulling mechanism for changing the shape of the forming cavity of the limiting mechanism.

[0008] By adopting the above technical solution, the support surface of the bracket is positioned above the top surface of the roller conveyor during stacking. After the steel pipes are stacked, the support surface is lowered below the top surface of the roller conveyor by the lifting mechanism. During the process, the pulling mechanism controls the shape of the forming cavity of the limiting mechanism to make it open, so that the bundled steel pipes can be removed. Then they are transported out through the roller conveyor. Finally, the bracket, limiting mechanism, lifting mechanism and pulling mechanism are restored to their original state for the next use. The device is easy to operate, avoids the process of installing or removing bolts, and improves production efficiency.

[0009] Optionally, the bracket includes a support beam for supporting the steel pipe, and the limiting mechanism includes lower limiting plates symmetrically fixed on both sides of the top surface of the support beam. The lower limiting plates are right-angled triangles, and upper limiting plates are symmetrically arranged above the lower limiting plates. The upper limiting plates and the lower limiting plates are rotatably connected by a connecting shaft. The pulling mechanism includes a pulling rope connected to the top of the upper limiting plate and a tension spring connected between the bottom of the upper limiting plate and the top surface of the support beam.

[0010] By adopting the above technical solution, the upper limit plate is rotated by the pull rope, making the molding cavity open. Then, the tension spring pulls the upper limit plate to rotate in the opposite direction, so that the upper limit plate returns to its original shape, and thus the molding cavity returns to its original shape.

[0011] Optionally, a base plate is provided below the support beam, and a vertical pole is fixedly connected to the bottom surface of the support beam. A vertical pipe is fixedly connected to the top surface of the base plate. The vertical pole slides through the vertical pipe. A groove is opened on the side wall of the vertical pipe along the vertical direction. A mounting frame extending outward through the groove is fixedly connected to the bottom of the vertical pole. A guide wheel is rotatably connected to the end of the mounting frame. The other end of the pull rope passes around the guide wheel and is connected to the top of the vertical pipe.

[0012] By adopting the above technical solution, during the process of the lifting mechanism controlling the beam to move downward, the upright pole drives the mounting frame and guide wheel to move downward, and then the guide wheel pulls the traction rope to control the upper limit plate to rotate outward, thereby using the power of the lifting mechanism to simultaneously act on the lifting and traction processes.

[0013] Optionally, the lifting mechanism includes a hydraulic cylinder vertically mounted on the top surface of the base plate, with the piston rod of the hydraulic cylinder connected to the support beam via a connecting block.

[0014] Optionally, a fixing ring three is fixedly connected to the bottom of the upper limit plate, a fixing ring four is fixedly connected to the top surface of the support beam, and a tension spring is installed between the fixing ring three and the fixing ring four.

[0015] Optionally, a fixing ring 1 is fixed to the top of the upper limit plate, a fixing ring 2 is fixed to the top of the riser, one end of the pull rope is connected to the fixing ring 1, and the other end is connected to the fixing ring 2. Attached Figure Description

[0020] The following combination Figures 1-3 The present invention will be described in further detail below.

[0021] This utility model discloses a steel pipe stacking device. (Refer to...) Figure 1 and Figure 2 The steel pipe stacking device is set between two adjacent roller conveyor lines 1. The device includes a bracket 2 for supporting steel pipes, a limiting mechanism 3 for controlling the stacking position of steel pipes, a lifting mechanism 4 for controlling the up and down movement of the supporting surface of the bracket 2, and a pulling mechanism 5 for changing the shape of the forming cavity of the limiting mechanism 3.

[0022] Reference Figure 2 and Figure 3 The bracket 2 includes a base plate 20, which is fixed to the ground by anchor bolts. A support beam 21 is horizontally arranged above the base plate 20. Uprights 22 are vertically fixed to the bottom surfaces at both ends of the support beam 21. A vertical pipe 23 is vertically fixed to the top surface of the base plate 20. The uprights 22 are slidably inserted into the vertical pipe 23.

[0023] Reference Figure 2 and Figure 3 The limiting mechanism 3 includes a lower limiting plate 30 symmetrically fixed to the top surface of the support beam 21. The lower limiting plate 30 is a right-angled triangular steel plate, and the hypotenuses of the two lower limiting plates 30 are arranged facing each other. An upper limiting plate 31 is symmetrically arranged above the lower limiting plate 30. The upper limiting plate 31 has the same shape as the lower limiting plate 30. The upper limiting plate 31 is rotatably connected to the lower limiting plate 30 through a connecting shaft 32.

[0024] Reference Figure 2 and Figure 3 The lifting mechanism 4 includes a hydraulic cylinder 40 vertically installed in the middle of the top surface of the base plate 20. The top of the piston rod of the hydraulic cylinder 40 is connected to the support beam 21 through a connecting block 41. The connecting block 41 serves to connect and distribute the force.

[0025] Reference Figure 2 and Figure 3The pulling mechanism 5 includes a first fixing ring 50 fixed to the right angle of the upper limit plate 31, a second fixing ring 51 fixed to the outer wall of the top of the riser 23, a vertical groove 230 opened on the side wall of the riser 23, a mounting bracket 52 fixed to the outer wall of the bottom of the upright 22, the mounting bracket 52 extending away from the hydraulic cylinder 40, a guide wheel 53 rotatably connected to the cantilever end of the mounting bracket 52, a pulling rope 54 connected to the first fixing ring 50, and the other end of the pulling rope 54 passing around the guide wheel 53 and connecting to the second fixing ring 51.

[0026] Reference Figure 2 and Figure 3 A fixing ring 35 is fixed to the end of the upper limit plate 31 near the connecting shaft 32. A fixing ring 46 is fixed to the top surface of the support beam 21 at the position directly below the connecting shaft 32. A tension spring 57 is installed between the fixing ring 46 and the fixing ring 35. The tension spring 57 pulls the upper limit plate 31 downward, so that the upper limit plate 31 and the lower limit plate 30 maintain a stable vertical symmetry, thereby forming a hexagonal forming cavity in the limiting mechanism 3.

[0027] The implementation principle of the steel pipe stacking device in this embodiment of the utility model is as follows: the steel pipes enter the forming cavity of the limiting mechanism 3 in sequence and are stacked and formed. Under the effective pulling action of the tension spring 57, the upper limit plate 31 remains stable and does not rotate due to the lateral thrust that the steel pipes may cause. At this time, the steel pipe group is supported by the support beam 21 and does not contact the roller conveyor line 1, that is, the top surface elevation of the support beam 21 is higher than the top surface elevation of the roller conveyor line 1.

[0028] After the steel pipe assembly is formed, the steel pipe is tied together. Then, the hydraulic cylinder 40 is controlled to retract, causing the support beam 21 to move downward. During the downward movement of the support beam 21, the mounting frame 52 and guide wheel 53 are driven to move downward, while the fixed ring 2 51 is fixed in position. Then, the pull rope 54 is pulled downward, causing the upper limit plate 31 to overcome the tension of the tension spring 57 and rotate to both sides. At this time, the tension spring 57 is elastically extended.

[0029] After the support beam 21 moves downward to a height lower than the top surface of the roller conveyor line 1, the hydraulic cylinder 40 stops retracting. At this time, the forming cavity formed by the upper limit plate 31 and the lower limit plate 30 is open, and the steel pipe assembly is supported only by the roller conveyor line 1. Starting the roller conveyor line 1 will smoothly transport the bundled steel pipes out. After the bundled steel pipes are output, the hydraulic cylinder 40 is controlled to lift the support beam 21 back to its original position. During this process, the tension spring 57 overcomes the tension of the pull rope 54 and drives the upper limit plate 31 to gradually return to its original position for the next use.

[0030] Throughout the entire palletizing and transportation process, only the lifting mechanism 4, the roller conveyor line 1, and the binding steel pipes need to be controlled by the staff. This eliminates the tedious process of installing or removing bolts, reduces the workload of the staff, and significantly improves the efficiency of the entire production process.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
