Description

Technical Field

[0001] The utility model relates to a transportation and installation device used in a construction process, in particular to a simple lifting, transportation and installation device. Background Art

[0002] Lifting is a complex process in the installation of various covers, pipes, and components for construction and municipal engineering projects. Covers or pipes are typically installed within trenches, often at a distance from the ground or with obstacles between the installation location and the material storage area. During installation, the covers must be transported to the installation site. However, in many cases, the trenches are deep or there are obstacles such as slopes or potholes between the trench and the construction materials, making over-travel difficult. Typically, cranes, manual lifting, or loading and moving materials using carts are employed. Manual lifting, climbing over mounds or moving materials up and down trenches, is difficult. Manual handling requires at least four people, and at least two more people are required to catch and move the covers and pipes within the trench before installing them. This is labor-intensive, time-consuming, and expensive, requiring a significant amount of labor and time to complete. It is not only labor-intensive and labor-intensive, but also poses certain safety risks. Furthermore, the transport of covers and pipes is prone to damage due to repeated loading and unloading, which is time-consuming and requires limited flexibility. When using a lifting crane, the drainage ditch cover or drainage pipe is light in weight, and each positioning takes a long time, resulting in low utilization rate, and sometimes construction cannot be carried out due to the limitation of small space; if a crane or hook machine is used for lifting and installation, it will cost a lot of machinery costs, and a large area needs to be reserved for parking before construction can begin, so it is very uneconomical.

DETAILED DESCRIPTION

[0028] like Figures 1 to 7 As shown, the utility model is a simple lifting, transporting and installing device, which includes a lifting frame 1, a rotating mechanism, a mobile supporting device and a lifting device.

[0029] like Figure 1 、 Figure 2 As shown, the lifting frame 1 is an A-shaped frame structure formed by welding steel pipes. The lifting frame 1 includes two long steel pipes 2 and a plurality of transverse short steel pipes 3. One end of the two long steel pipes 2 is welded to form a whole and the other end is open to form an A-shaped frame structure. The welded end of the long steel pipe 2 (the end where the two long steel pipes 2 are welded into one body) forms a lifting end 21, which is used to install a lifting device. The open end of the long steel pipe 2 forms two handrails 22, which are used to push the mobile support device or rotate the lifting frame 1. A plurality of transverse short steel pipes 3 are respectively connected in parallel between the inner sides of the two long steel pipes 2, and the short steel pipes play a role in pulling and reinforcing. A short winding steel pipe 17 capable of winding a steel wire rope 20 is provided on one side of the handrail 22. The short winding steel pipe 17 is connected to the upper side of the long steel pipe 2 close to the handrail 22 by welding, and is used for winding and tying the lifting steel wire rope 20. A short limiting steel bar 18 is welded horizontally on the upper part of the short winding steel pipe 17 to prevent the steel wire rope 20 from slipping out.

[0030] like Figure 1 、 Figure 2As shown, the lifting device is connected to the lifting frame 1. The lifting device includes a pulley block 19 and a steel wire rope 20. The pulley block 19 is installed at the lifting end 21 of the A-shaped frame structure. The use of the pulley block 19 can reduce the gravity of the hoisted object. The steel wire rope 20 passes over the pulley block 19 and extends from the lifting end 21 to the side of the handrail 22, and is wound around the winding short steel pipe 17 and fixed.

[0031] like Figure 1 and Figures 3 to 5 As shown, the rotating mechanism is connected between the lifting frame 1 and the mobile support device. The rotating mechanism comprises two circular steel plates and a ball bearing 16 positioned between them. The upper circular steel plate 4 is located on the upper side, while the lower circular steel plate 5 is located on the lower side. The two circular steel plates are connected at the center by bolts 10 to form a single structure. The lower circular steel plate 5 has a circular groove 15 recessed downward on its upper surface. The depth of the groove 15 is less than the diameter of the ball bearing 16, which is positioned within the groove. The upper circular steel plate 4 presses against the ball bearing 16. The two circular steel plates have corresponding through-holes in their centers, through which bolts 10 pass to connect the upper and lower circular steel plates to form a single structure. Under the action of the ball bearing 16, the upper circular steel plate 4 can rotate 360 ​​degrees relative to the lower circular steel plate 5. The ball bearing 16 isolates the upper and lower circular steel plates, reducing friction between them and promoting rolling. The upper surface of the upper circular steel plate 4 is connected to an upwardly extending steel plate upper support frame 11, and the lower surface of the lower circular steel plate 5 is connected to a downwardly extending steel plate lower support frame 12. The top end of the steel plate support frame 11 is connected to the middle of the lifting frame 1, and the bottom end of the steel plate lower support frame 12 is connected to the movable support device. The overall structure formed by the connection between the upper circular steel plate and the lifting frame 1 can rotate relative to the overall structure formed by the connection between the lower circular steel plate and the movable support device. In this embodiment, the steel plate support frame 11 is two short steel pipes in an inverted eight shape. The bottom ends of the two short steel pipes are connected to the upper surface of the upper circular steel plate 4, and the top ends of the two short steel pipes are respectively connected to the two long steel pipes 2 of the lifting frame 1. The steel plate lower support frame 12 is two vertical steel pipes. The top ends of the two vertical steel pipes are respectively connected to the lower surface of the lower circular steel plate 5, and the bottom ends of the two vertical steel pipes are respectively connected to the tire connecting shaft 7.

[0032] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 7As shown, the mobile support device includes a tire connecting shaft 7, support legs 8, and a rotating tire 6. Two rotating tires 6 are mounted on either end of the tire connecting shaft 7. The two rotating tires 6 can be 100 / 90-18-inch pneumatic motorcycle tires. Support leg mounting holes 13 are provided near the ends of the tire connecting shaft 7. These holes are formed by extending the tire connecting shaft 7 from the outside of the rotating tire 6. The two support legs 8 are mounted in these holes, extending downward from the top of the tire connecting shaft 7. A row of positioning holes 14 is opened on the supporting foot 8, which passes through the opposite side surfaces of the supporting foot 8. The mobile supporting device also includes a locking steel bar 9 that can be positioned in the positioning hole 14 and stuck on the upper side of the supporting foot mounting hole 13 while the supporting foot 8 is positioned in the supporting foot mounting hole 13. When the supporting foot 8 is installed in the supporting foot mounting hole 13, the locking steel bar 9 passes through one of the positioning holes 14 of the supporting foot 8 to determine the length of the supporting foot 8 extending out of the lower side of the tire connecting shaft 7. If it is necessary to push the simple lifting and transportation installation device, the supporting foot 8 can be adjusted upward to reduce the support foot 8 from being worn out of the ground. If it is necessary to fix the simple lifting and transportation installation device at a certain position, the supporting foot 8 can be adjusted downward so that the section of the supporting foot 8 touches the ground, thereby increasing the stability of the simple lifting and transportation installation device.

[0033] During operation, after the simple lifting and transporting installation device is carted to the lifting point, the lifting frame 1 is manually operated, using the handrail to push the simple lifting and transporting installation device to the appropriate position. The device is then pushed to the material placement point, clearing any obstacles near the construction area. After stopping, the adjustable support legs 8 are lowered. Once the support legs 8 touch the ground, they are threaded through locking bars 9 in the positioning holes 14 adjacent to the tire connecting shaft 7, securing the simple lifting and transporting installation device. By rotating the handrail, the rotating mechanism moves the lifting frame, and the rotating ball bearings 16 drive the lifting arm of the lifting frame 1 through a full 360° rotation. Using the handrail, the worker rotates the lifting end 21 to the material storage area. After securing the cover plate with the wire rope 20, the wire rope 20 is tightened at the rear end (the end where the handrail is located). After the wire rope 20 is shortened to the desired length, it is tied to the short steel pipe 17 at the rear end for securement. By rotating the handrail, the boom of the lifting frame 1 is rotated, and after rotating to the appropriate position, the wire rope 20 is slowly lowered, and the materials are installed after manual cooperation. After the transportation and lifting are completed, the materials are pushed to the next construction site.

[0034] The above embodiments are only preferred embodiments of the present invention. The structure of the present invention is not limited to the forms listed in the above embodiments. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
