Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a device for moving and placing building steel pipes. Background Technology

[0002] In construction, steel pipes are one of the commonly used building materials and are generally placed on storage devices for centralized stacking.

[0003] Most current steel pipe placement devices are fixed structures, with steel pipes placed in a fixed space. The steel pipes are stacked one on top of the other in a fixed space, making it very inconvenient to retrieve specific steel pipes. If it were possible to easily retrieve specific types of steel pipes, it would bring great convenience. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a device for moving and placing building steel pipes.

[0005] The technical solution adopted by this utility model is as follows: A mobile placement device for building steel pipes includes a placement box with a front opening. Doors are rotatably installed on both sides of the front opening, and locks are provided between the opposite edges of the two doors. Four casters are rotatably installed at the bottom corners of the placement box. A connector is fixedly connected to the bottom left side of the placement box. Slide rails are fixedly connected to the front and rear sides of the left and right inner walls of the placement box, and the slide rails are vertically arranged. Three lifting plates are installed inside the placement box, distributed vertically. Slider blocks are fixedly connected to the front and rear sides of the left and right ends of each lifting plate. Two sliders on one side slide and engage with two slide rails on the left and right sides of the same side. Adjustable placement components are provided between adjacent lifting plates. An adjustable placement component is provided between the bottom lifting plate and the bottom wall of the placement box. Slide rails are fixedly connected to the bottom sides of the top lifting plate and the bottom wall of the placement box. Slide rails are fixedly connected to the upper and lower ends of the lifting plate between the top lifting plate and the bottom wall of the placement box.

[0006] The adjustable placement assembly includes a fixed plate, which is fixedly connected to the left side of the bottom wall of the placement box and the top left side of the upper lifting plate. The top of the uppermost lifting plate does not have a fixed plate. Several lower movable plates are evenly distributed to the right of the fixed plate. Several upper movable plates are located above the lower movable plates, with the lower and upper movable plates staggered to each other. A movable plate is located to the right of the rightmost lower movable plate. Slider 2 is fixedly connected to the front and rear ends of the top of the upper movable plate, the front and rear ends of the bottom of the lower movable plate, and the front and rear ends of the bottom of the movable plate. The upper and lower slider 2 are slidably engaged with the upper and lower sliding rails 2, respectively. A placement frame is rotatably connected between the right ends of the fixed plate and the left ends of the leftmost upper movable plate. A placement frame is rotatably connected between the two ends of the upper movable plate and the left and right ends of the two adjacent lower movable plates below. The right ends of the rightmost upper movable plate are rotatably connected to the left and right ends of the movable plate. The two ends of the side are rotatably connected to the placement frame. The right ends of the leftmost upper moving plate are rotatably connected to the left ends of the adjacent leftmost lower moving plate. Several placement frames in each layer are zigzag-shaped. The inner side of the placement frame has several straight rollers, which are distributed front and back. The two ends of the straight rollers are rotatably connected to the top and bottom of the inner side wall of the placement frame, respectively. The ball nut is fixedly connected to the bottom middle of the movable plate. There are fixed seats on both the left and right sides of the ball nut. The two fixed seats are fixedly connected to the upper part of each lifting plate. The top of the inner bottom wall of the placement box is fixedly connected to two fixed seats. A through hole is opened in the middle of the right side wall of the placement box. The through hole extends vertically. A screw rod is rotatably connected between the two fixed seats in the same layer. The ball nut is threaded onto the screw rod. The right end of the screw rod passes through the through hole. There is a gap between the screw rod and the inner wall of the through hole. A handwheel is fixedly connected to the outer wall of the right end of the screw rod.

[0007] The beneficial effects of this utility model are: This invention uses a handwheel to drive a lead screw to rotate, which moves the movable plate and in turn causes the placement frame to change its tilt angle and the lifting plate to move up and down, thus changing the space between the placement frames. This allows it to adapt to the placement needs of building steel pipes of different diameters and improves the versatility of the device.

[0008] The screw and ball nut have a self-locking function. After adjusting the angle of the placement frame and the position of the lifting plate to clamp the pipe, it can ensure that the pipe is stably fixed in the placement device, preventing the pipe from loosening or falling off during movement.

[0009] The straight rollers inside the placement frame reduce friction between the pipe and the placement frame, making it easier for the steel pipe to be installed into the placement device, reducing the difficulty of operation and improving work efficiency. Attached Figure Description

[0012] like Figure 1-6 As shown: A mobile placement device for building steel pipes includes a placement box 1 with a front opening. Doors 2 are rotatably installed on both the left and right sides of the front opening of the placement box 1, and door locks 3 are provided between the opposite edges of the two doors 2. Four casters 4 are rotatably installed at the bottom corners of the placement box 1. A connector 5 is fixedly connected to the bottom left side of the placement box 1. Slide rails 6 are fixedly connected to the front and rear sides of the left and right inner walls of the placement box 1, and the slide rails 6 are vertically arranged. Three lifting plates 7 are installed inside the placement box 1, distributed vertically. The left and right ends of the lifting plates 7 are... The rear side is fixedly connected to slider 8. The left and right sliders 8 on one side are respectively slidably engaged with the left and right slide rails 6 on the other side. An adjustable placement component is set between the upper and lower adjacent lifting plates 7. An adjustable placement component is set between the lowermost lifting plate 7 and the inner bottom wall of the placement box 1. The bottom sides of the uppermost lifting plate 7 are fixedly connected to slide rails 9. The inner bottom wall of the placement box 1 is fixedly connected to slide rails 9. The upper and lower ends of the lifting plate 7 between the uppermost lifting plate 7 and the inner bottom wall of the placement box 1 are respectively fixedly connected to slide rails 9.

[0013] The adjustable placement assembly includes a fixed plate 13, which is fixedly connected to the left side of the bottom wall of the placement box 1 and the top left side of the upper lifting plate 7. The top of the uppermost lifting plate 7 does not have a fixed plate 13. To the right of the fixed plate 13 are several lower movable plates 11, evenly distributed left and right. Above the lower movable plates 11 are several upper movable plates 10, staggered left and right. To the right of the rightmost lower movable plate 11 is a movable plate 14. The top front and rear ends of the upper moving plate 10, the bottom front and rear ends of the lower moving plate 11, and the bottom front and rear ends of the movable plate 14 are all fixedly connected to slider 2 12. The upper and lower slider 2 12 are respectively slidably engaged with the upper and lower sliding rails 2 9. The right ends of the fixed plate 13 are rotatably connected to the left ends of the leftmost upper moving plate 10 with the placement frame 15. The two ends of the upper moving plate 10 are rotatably connected to the left and right ends of the two adjacent lower moving plates 11. The right ends of the rightmost upper moving plate 10 are connected to the left ends of the movable plate 14 with the placement frame 15. The placement frames 15 are rotatably connected between each other. The right ends of the leftmost upper movable plate 10 are rotatably connected to the left ends of the adjacent leftmost lower movable plate 11. Several placement frames 15 in each layer are zigzag-shaped. Several straight rollers 16 are distributed on the inner side of the placement frame 15. The two ends of the straight rollers 16 are rotatably connected to the top and bottom of the inner side wall of the placement frame 15, respectively. Ball bearing nuts 17 are fixedly connected to the bottom middle of the movable plate 14. The left and right sides of the ball bearing nuts 17 are fixed. Fixed seats 18 are fixedly connected to the upper part of each lifting plate 7. The top of the inner bottom wall of the placement box 1 is fixedly connected to two fixed seats 18. A through hole 21 is opened in the middle of the right side wall of the placement box 1. The through hole 21 extends vertically. A screw rod 19 is rotatably connected between the two fixed seats 18 on the same layer. A ball nut 17 is threaded onto the screw rod 19. The right end of the screw rod 19 passes through the through hole 21. There is a gap between the screw rod 19 and the inner wall of the through hole 21. A handwheel 20 is fixedly connected to the outer wall of the right end of the screw rod 19.

[0014] When it is necessary to place building steel pipes of different diameters, the operator turns the handwheel 20 on the right side wall of the placement box 1. The handwheel 20 drives the lead screw 19 to rotate. When the lead screw 19 rotates, the ball nut 17, which is threadedly connected to the lead screw 19, will move along the lead screw 19. Since the ball nut 17 is fixedly connected to the bottom center of the movable plate 14 of the adjustable placement component, the movable plate 14 will move back and forth on the slide rail 9 via the slider 2 12.

[0015] When the movable plate 14 moves, it will cause the placement frame 15 connected to it to change its tilt angle. At the same time, since the placement frames 15 are rotatably connected to each other, as well as to the fixed plate 13, the upper moving plate 10, and the lower moving plate 11, the entire adjustable placement assembly will adjust its shape as the movable plate 14 moves.

[0016] The adjustable placement component's shape change causes the lifting plate 7 to move up and down, thereby changing the space between adjacent placement frames 15. Tightening the locking nut 22 ensures that it abuts against the right outer wall of the placement box 1, preventing the lead screw 19 from rotating freely.

[0017] The building steel pipe is placed in the placement frame 15. The straight rollers 16 inside the placement frame 15 are distributed back and forth and their two ends are rotatably connected to the top and bottom of the inner side wall of the placement frame 15. This reduces the friction between the pipe and the placement frame 15 and makes it easier to install the pipe. After the pipe is placed, the angle of the placement frame 15 and the position of the lifting plate 7 are adjusted by continuing to rotate the handwheel 20 so that the placement frame 15 clamps the pipe. The self-locking function of the screw 19 and the ball nut 17 is used to fix the pipe in the placement device.

[0018] The placement device can be moved to a designated position by using the movable wheel 4. When it is necessary to take out the pipe, open the door lock 3, pull open the box door 2, and take out the pipe from the front opening of the placement box 1.
