Description

Technical Field

[0001] The present invention relates to the field of steel pipe manufacturing and processing, and particularly to a steel pipe shelf that facilitates the picking and placing of steel pipes. Background Art

[0002] Generally, round steel pipes are stacked on the ground. Steel pipes of different specifications cannot be placed together and need to be stacked in multiple areas, occupying a relatively large area, which affects the movement of personnel and the transportation of equipment and raw materials. At the same time, since they are all stacked on the ground, the distinction between steel pipes of different specifications is not obvious, making it inconvenient to use the steel pipes. When the irregular steel pipes are stacked in layers on the shelf, the floor area is reduced, and it is also convenient to distinguish. When the round steel pipes are stacked on the supporting plate of the shelf, locking parts are needed to fix them to prevent the steel pipes from rolling off the shelf. When in use, the locking parts are opened, the steel pipes are taken down, and then locked again. Moreover, the steel pipes are limited by the supporting plates on their upper and lower sides, making it inconvenient to pick and place. Summary of the Invention

[0003] The purpose of the present invention is to provide a steel pipe shelf that facilitates the picking and placing of steel pipes, with the advantages of facilitating the fixing and distinguishing of steel pipes.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A steel pipe shelf that facilitates the picking and placing of steel pipes includes columns. There are multiple columns arranged left and right. On the left and right sides of each column, multiple crossbeams are respectively fixedly connected. The crossbeams on both sides of the column are symmetrical left and right, and the column is located in the middle of the crossbeam. A cavity is formed inside the crossbeam. The opening directions of the cavities of the crossbeams on the same side of the column are the same, and the opening directions of the cavities of the crossbeams on different sides of the column are opposite. It also includes multiple U-shaped brackets. The bottom of the U-shaped bracket is fixedly connected with a horizontal sliding rod through a connecting rod. A chute is formed between the sliding rod and the bottom of the U-shaped bracket. The length of the sliding rod is approximately equal to the length of the crossbeam, and the length of the U-shaped bracket is approximately equal to half of the length of the crossbeam. The sliding rod penetrates into the inside of the crossbeam from the opening of the crossbeam cavity. The U-shaped bracket is located above the crossbeam, and the opening of the U-shaped bracket faces upward. The sliding rod is slidably connected with the crossbeam, and a limiting mechanism is provided between them. A rotating shaft I is rotatably connected at the opening of the cavity of each crossbeam. A friction wheel is integrally formed on the rotating shaft I. A groove is formed by the middle part of the outer wall of the friction wheel sinking into its inside. A connecting rod is fixedly connected between the friction wheels on the same height of the same side of the adjacent two columns, connecting multiple columns into a whole. A T-shaped strip is integrally formed at the bottom of each sliding rod. The middle part of the T-shaped strip is embedded in the groove of the friction wheel and is in rolling connection with the friction wheel.

[0005] With the above technical solution, multiple areas are formed between the columns and the crossbeams. The parts of the crossbeams on the front and rear sides of the columns at the same height are each an area. Steel pipes of the same specification are placed on the crossbeams at the same height in front of or behind the columns, and the steel pipes are located above the opening bottom of the U-shaped brackets on the crossbeams. The steel pipes are blocked by the two side parts of the U-shaped brackets and will not roll off the crossbeams. Rotate one of the connecting rods on the crossbeam where the steel pipe is located. The rotation of this connecting rod drives the rotation of other connecting rods on the layer where the steel pipe is located through the first rotating shaft, thereby driving the rotation of the friction wheels on the entire layer of crossbeams where the steel pipe is located. The rotation of the friction wheels drives the movement of the sliding rods on the entire layer of crossbeams, thereby driving the movement of the U-shaped brackets. The U-shaped brackets drive the steel pipes to move a distance equal to half the length of the crossbeam, so that the steel pipes leave from between the upper and lower layers of crossbeams where they are located. Then, the steel pipes can be removed from the U-shaped brackets by manual or crane and transported away. When taking materials, it will not be blocked by the crossbeams above the steel pipes, which is more convenient; Steel pipes of different specifications are placed on the crossbeams of different layers of the steel pipe rack for better distinction and faster material taking.

[0006] Preferably, it further includes a connecting frame, which is located on the side of the outermost column. A transmission shaft is connected between the connecting frame and the friction wheel of the crossbeam on the outermost column. The transmission shaft includes a connecting rod and a second rotating shaft. The second rotating shaft is fixedly connected to the connecting rod. The second rotating shaft is rotatably connected to the connecting frame. The transmission shafts of the crossbeams on the same side of the end column are located on the same side of the connecting frame.

[0007] With the above technical solution, rotate one of the transmission shafts on the connecting frame. The rotation of the transmission shaft drives the rotation of the first rotating shaft connected to it. The first rotating shaft drives the rotation of other connecting rods on the same side and at the same layer of the column through the connecting rod, thereby driving the rotation of the friction wheels of this layer, and further driving the movement of the U-shaped brackets and the steel pipes on them.

[0008] Preferably, transmission mechanisms are respectively arranged between multiple transmission shafts on the same side of the connecting frame and the connecting frame. The transmission mechanisms are sprocket chains. There are multiple pairs of sprocket chains. Each transmission shaft is connected to the connecting frame through a pair of sprocket chains. Each pair of sprocket chains respectively includes a driven wheel and a driving wheel. The driven wheel is fixedly connected to the second rotating shaft of the transmission shaft. The driving wheel is fixedly connected with a third rotating shaft. The third rotating shaft passes through the connecting frame and is rotatably connected to the connecting frame. A square shaft is integrally formed at the end of the third rotating shaft away from the driving wheel. The chain connects the driving wheel and the driven wheel. The driven wheels respectively connected to the transmission shafts on the same side of the connecting frame are all located in the middle of the same side vertical plane of the connecting frame. It further includes a hand crank, and a square groove corresponding to the square shaft is opened at the end of the hand crank.

[0009] With the above technical solution, the square groove of the hand crank holds the square shaft on one of the driving wheels located in the middle of one side of the connecting frame. Rotating the hand crank, the hand crank drives the driving wheel to rotate through the square shaft. The driving wheel drives the transmission shaft fixedly connected with the driven wheel to rotate through the chain. The transmission shaft drives the friction wheel on the same layer as it on the column to rotate. When the layer where the cross beam is located is relatively high or low and not convenient to rotate, the driving wheel at the height of the middle position of the connecting frame can be rotated, and then the friction wheel of the cross beam at a higher or lower position can be driven to rotate through the chain and the driven wheel.

[0010] Preferably, the limiting mechanism includes a first bolt and a nut. The first bolt is located at the opening of the cross beam cavity. The first bolt passes through both sides of the cross beam cavity and is fixedly connected to the cross beam through the nut. A convex block is integrally formed on the upper part of the sliding rod.

[0011] With the above technical solution, the U-shaped bracket drives the sliding rod to move in the cross beam cavity. When the convex block on the upper part of the sliding rod touches the first bolt, the sliding rod stops moving, preventing the sliding rod from completely disengaging from the cavity of the cross beam, so as to prevent the U-shaped frame and the steel pipe on it from falling off the cross beam and causing a safety accident.

[0012] Preferably, the U-shaped bracket is fixedly connected to the top end of the column. It further includes a U-shaped bracket. The bracket is fixedly connected to the top end of the column.

[0013] With the above technical solution, the steel pipe can be placed in the opening of the bracket, increasing the storage quantity of the steel pipe rack.

[0014] Preferably, the connecting rod is fixedly connected to the first rotating shaft and the second rotating shaft through a connecting piece. The connecting piece includes a second bolt and a nut. The connecting rod is a hollow rod. The ends of the first rotating shaft and the second rotating shaft penetrate into the interior of the hollow rod. The second bolt between the first rotating shaft and the connecting rod passes through both of them, and the nut is threadedly connected to the second bolt.

[0015] With the above technical solution, by screwing the nut of the second bolt, the first rotating shaft and the connecting rod between them are clamped, thereby fixing the first rotating shaft and the connecting rod.

[0016] Preferably, a cross brace is fixedly connected between two adjacent columns.

[0017] With the above technical solution, the stability of the steel pipe rack is increased. Description of the Drawings

[0022] See Figure 2 , Figure 4 , Figure 7 and Figure 9, a connecting frame 8 is placed on the side of the outermost column 1. A transmission shaft 9 is connected between the friction wheel 5 on the cross beam 2 of the outermost column 1 and the connecting frame 8.

Then, the steel pipe can be removed from the U-shaped bracket 3 by manual or crane and transported away. When taking the material, it will not be blocked by the cross beam 2 above the steel pipe, which is more convenient; Steel pipes of different specifications are placed on the cross beams 2 of different layers of the steel pipe rack for better distinction and more convenient material taking.
