Description

Technical Field

[0001] This utility model relates to the technical field of building component handling devices, and more specifically, to a beam and column handling device. Background Technology

[0002] Beams and columns are crucial structural components of buildings. Beams are horizontal load-bearing members, and columns are vertical load-bearing members. Together, they form a frame that supports the weight of the entire building and distributes the gravitational load, primarily undertaking the building's load-bearing and support functions. Due to their significant weight, auxiliary devices are often used to assist in their handling. Existing handling equipment can lift and move beams and columns, but it cannot rotate or adjust them during transport. This limitation in rotation means that once the beams and columns are moved to their designated location, they cannot be rotated or adjusted according to their installation orientation, resulting in limited flexibility in handling and use. Utility Model Content

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-4 As shown in the figure, the beam and column handling device proposed in this embodiment can be used to move single beams and columns within the factory area, and can also be used for short-distance movement of other column-shaped materials.

[0038] This beam and column handling device mainly includes a traveling component 1, a lower support component 2, an upper support component 3, and a clamping component 4 connected in sequence. The traveling component 1 is used for the movement of this beam and column handling device. The lower support component 2 is connected to the traveling component 1, supports the upper support component 3, and is rotatably connected to the upper support component 3. The upper support component 3 supports and connects to the clamping component 4. The clamping component 4 is used to clamp the beam and column, driving the beam and column to move. When the beam and column need to be adjusted in angle, the rotation of the upper support component 3 drives the clamping component 4 to rotate by a certain angle, thereby rotating the beam and column, realizing the movement and rotatable unloading of the beam and column.

[0039] The walking component 1 may include an axle 11 and wheels 12 rotatably connected to both ends of the axle 11. The wheels 12 may be the wheels of a construction site handcart, and their height should be convenient for personnel to push.

[0040] The lower support member 2 may include a lower support column 21 vertically connected to the middle of the axle 11. The lower support column 21 may be integrally connected to the axle 11. The height of the lower support column 21 may be equal to or slightly higher than the radius of the axle 11.

[0041] The upper support member 3 may include an upper support column 31 rotatably connected to the lower support column 21. The height of the upper support column 31 may be the same as or slightly higher than the lower support column 21. A transport rod 34 is vertically connected to the upper end of the upper support column 31. The distance between the front end of the transport rod 34 and the upper support column 31 is less than the distance between the rear end of the transport rod 34 and the upper support column 31. The front end of the transport rod 34 is one end connected to the clamping member 4. The upper support column 31 and the lower support column 21 together support the transport rod 34. The upper end of the upper support column 31 extends beyond the wheel 12. The transport rod 34 uses the lever principle to rotate around the wheel axle 11 as the fulcrum, thereby causing the clamping member 4 at the front end to tilt upwards and lift the beam column. When lifting and moving the beam column, the upper support column 31 and the lower support column 21 are fixedly connected together and cannot rotate. The transport rod 34 is perpendicular to the wheel axle 11. When it is necessary to rotate the beam column, the fixed connection between the upper support column 31 and the lower support column 21 is released, and the upper support column 31 can rotate at any angle. The diameter and specifications of the lower support column 21, upper support column 31, and transport rod 34 should be able to stably support and lift the beam and column.

[0042] To balance the lifting of the beam and column, the clamping component 4 may include a horizontal bar 41 and clamps 42 connected to both ends of the horizontal bar 41. The middle part of the horizontal bar 41 is vertically connected to the front end of the transport rod 34, and a handle 5 is provided at the rear end of the transport rod 34. Both clamps 42 of the clamping component 4 are clamped onto the beam and column. When a person presses the handle 5, the transport rod 34 is lifted, and the beam and column are raised horizontally. Then, the person pushes the handle 5 to start moving the beam and column. The handle 5 may be covered with sponge to facilitate hand operation and improve hand comfort.

[0043] The length of the upper support column 31 can be the same as or slightly greater than the length of the lower support column 21. When moving, the transport rod 34 should be basically horizontal, the handle 5 should be at a height that is easy for personnel to push, and the front end of the transport rod 34 should have sufficient lifting height.

[0044] In one specific embodiment of this utility model, in order to stabilize rotation, the inner and outer diameters of the lower support column 21 and the upper support column 31 are the same, and the lower support column 21 and the upper support column 31 can be cylindrical or square columns of the same specifications.

[0045] To ensure smooth rotation of the upper support column 31, the upper support column 31 and the lower support column 21 are connected by a bearing. The bearing is a thrust bearing 23, which has a high load-bearing capacity, can withstand large axial loads, and can ensure that the rotating shaft will not undergo excessive deflection when bearing loads.

[0046] A bearing mounting hole 22 is provided at the center of the end of the lower support column 21 furthest from the axle 11. The inner diameter of the bearing mounting hole 22 matches the outer diameter of the base of the thrust bearing 23, and the height of the bearing mounting hole 22 is the same as the height of the thrust bearing 23. The thrust bearing 23 is installed inside the bearing mounting hole 22, and both base positions of the thrust bearing 23 are fixed inside the bearing mounting hole 22. A central rod 32 is provided at the center of the lower end of the upper support column 31, and its height and diameter match those of the central hole of the thrust bearing 23. When the upper support column 31 and the lower support column 21 are connected together, the central rod 32 passes through the thrust bearing 23. The thrust bearing 23 and the central rod 32 connect the lower support column 21 and the upper support column 31 together. The central rod 32 is fixed in the center of the ball bearing cage of the thrust bearing 23. The central rod 32 can rotate smoothly through the rotation of the ball bearing cage, facilitating the rotation of the transport rod 34.

[0047] In one specific embodiment of this utility model, to facilitate the positioning of the transport rod 34 during transport, a first flange 24 is provided on the outer periphery of the end of the lower support column 21 away from the axle 11, and a second flange 33 is provided on the outer periphery of the ends of the upper support column 31 adjacent to the lower support column 21. The first flange 24 and the second flange 33 are the same size, and mounting holes are evenly provided on the first flange 24 and the second flange 33 respectively. After the upper support column 31 and the lower support column 21 are connected, the first flange 24 and the second flange 33 fit together. During transport, the transport rod 34 is perpendicular to the axle 11, and the mounting holes on the first flange 24 and the second flange 33 are aligned vertically, and positioning pins 8 can be used for positioning.

[0048] The positioning pin 8 may include a rod and a circular plate connected to the upper end of the rod. The pin can be inserted into the mounting holes that are aligned vertically. The circular plate can be cut from a 5mm thick steel plate and is positioned above the aligned mounting holes.

[0049] To prevent the positioning pin 8 from being lost, a connecting rope 7 is attached to the outer wall of the lower support column 21, and the connecting rope 7 is connected to the top of the positioning pin 8. During relocation, the mounting holes on the first flange 24 and the second flange 33 are aligned vertically, and the positioning pin 8 is inserted into the nearest pair of aligned mounting holes to position and connect the first flange 24 and the second flange 33, preventing the upper support column 31 from rotating. When rotating the transport rod 34, the positioning pin 8 is removed.

[0050] In one specific embodiment of this utility model, for the secure transport rod 34, the transport rod 34 may include a sleeve 341 and a long tube 342 passing through the sleeve 341. The outer diameter of the long tube 342 is adapted to the inner diameter of the sleeve 341, and the middle part of the sleeve 341 is fixedly connected to the upper end of the upper support column 31. After the long tube 342 is inserted into the sleeve 341, the distance between the front end of the long tube 342 and the middle part of the sleeve 341 is less than the distance between the rear end of the long tube 342 and the middle part of the sleeve 341. The specific distances of both ends from the middle part of the sleeve 341 can be determined according to the weight of the beam or column to be moved, which should facilitate the transport rod 34 to lift the beam or column. The sleeve 341 is connected to the upper support column 31, and the upper support column 31 drives the sleeve 341 to rotate or lift, and the sleeve 341 drives the long tube 342 to rotate or lift, resulting in a more stable and powerful drive.

[0051] In one specific embodiment of this utility model, in order to ensure the stability and firmness of the transport rod 34, oblique reinforcing rods 35 are respectively connected between the two ends of the sleeve 341 and the upper support 31. The reinforcing rods 35 can strengthen the stable connection between the sleeve 341 and the upper support 31, and are not easily deformed during long-term use.

[0052] In one specific embodiment of this utility model, in order to stably clamp the beam and column, the clamp 42 may include a cylindrical clamp 44 connected to the crossbar 41 via a hook 43. A hook 43 is provided at both ends of the crossbar 41, and the hooks 43 are used to suspend the cylindrical clamps 44. The two cylindrical clamps 44 can horizontally clamp and suspend the cylindrical beam and column. The cylindrical clamps 44 can be selected according to the weight and diameter of the beam and column, and the hooks 43 facilitate the replacement of different cylindrical clamps 44.

[0053] In one specific embodiment of this utility model, the cylindrical clamp 44 may include a hanging ring 441 and two U-shaped rods 442 connected to the hanging ring 441. A shaft 443 is connected between the ends of the two straight rods of the U-shaped rods 442. A clamping plate 444 is rotatably connected to the shaft 443. The length of the shaft 443 is slightly greater than the thickness of the clamping plate 444.

[0054] The clamping plate 444 may include a long strip plate 445 and an arc-shaped plate 446 connected to one end of the long strip plate 445. A shaft hole is provided at the other end of the long strip plate 445, and the shaft hole passes through the shaft rod 443. The long strip plates 445 of the two clamping plates 444 cross and are rotatably connected together. The lower ends of the arc-shaped plates 446 of the two clamping plates 444 face each other. When the arc-shaped plates 446 of the two clamping plates 444 are exactly abutted together, the shape formed can accommodate the cross section of the beam and column. The beam and column to be transported are clamped between the arc-shaped plates 446 of the two clamping plates 444.

[0055] When the lifting rod 34 is raised, the crossbar 41 moves upward, causing the hanging ring 441 to lift the two U-shaped rods 442. The rectangular plates of the two clamping plates 444 clamp together like pliers, causing the two arc-shaped plates 446 to move closer together, clamping the beam and column between the two arc-shaped plates 446. The two cylindrical clamps 44 have a certain distance between them, which can drive the beam and column to be lifted horizontally.

[0056] In one specific embodiment of this utility model, in order to protect the appearance of the beams and columns, a rubber sleeve 6 is fitted onto the curved plate 446. The contact between the beams and columns and the rubber sleeve 6 can prevent the steel curved plate 446 from damaging the surface of the beams and columns.

[0057] In one specific embodiment of this utility model, to ensure the stability of the lower support column 21, reinforcing diagonal braces 25 can be connected between the wheel axle 11 and both ends of the lower support column 21. The reinforcing diagonal braces 25 can stably support the lower support column 21 and prevent the lower support column 21 from tilting or deforming during long-term use.

[0058] In one specific embodiment of this utility model, in order to provide sufficient lifting space for the beam and column, the radius of the wheel 12 is not less than 30cm. The diameter of the wheel 12 is not less than 60cm, so that after the lower support column 21, the upper support column 31, and the transport rod 34 are connected, the front end of the transport rod 34 has sufficient upward tilting height, allowing the beam and column to be easily lifted off the ground and moved stably.

[0059] The beam and column handling device according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the beam and column handling device proposed in the present invention without departing from the scope of the present invention.
