[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] The lifting and transporting device provided by this utility model can quickly transport the concrete foundation 100 to the designated location, reducing the labor intensity of construction workers and improving construction efficiency.

[0035] like Figures 1-6As shown, the lifting and transporting device is used to lift a concrete foundation 100. The concrete foundation is fixedly connected to a lifting flange 101. The lifting and transporting device includes a support assembly 1 and a lifting assembly 2. The support assembly 1 includes a support frame 11, a first connecting piece 12, a wheel axle 13, and two traveling wheels 14. The two traveling wheels 14 are rotatably connected to both ends of the wheel axle 13. The support frame 11 is fixedly connected to the wheel axle 13, and the first connecting piece 12 is fixedly connected to the support frame 11. The lifting assembly 2 includes a lifting lever 21, a connecting sleeve 22, a fastener 23, a second connecting piece 24, and a lifting component 25. The lifting lever 21 can be slidably connected to the connecting sleeve 22. The connecting sleeve 22 has a fastening threaded hole 221. The fastener 23 passes through the fastening threaded hole 221 and is screwed to the connecting sleeve 22. The fastener 23 can abut against the lifting lever 21 to fix the lifting lever 21 and the connecting sleeve 22. The second connecting member 24 is fixedly connected to the connecting sleeve 22, and the second connecting member 24 is movably connected to the first connecting member 12 to adjust the distance between the lifting lever 21 and the wheel axle 13. The lifting member 25 is connected to one end of the lifting lever 21 and is configured to connect to the lifting flange 101.

[0036] The lifting and transporting device provided by this utility model includes a support assembly 1 and a lifting assembly 2. The support assembly 1 includes wheels 14 for easy movement on factory roofs, reducing the labor intensity of construction workers. The lifting assembly 2 includes a lifting lever 21 and a connecting sleeve 22. The lifting lever 21 can slide within the connecting sleeve 22. One end of a second connecting member 24 is fixedly connected to the connecting sleeve 22, and the other end is fixedly connected to a first connecting member 12. The first connecting member 12 is fixedly connected to the support assembly. When construction workers press the end of the lifting lever 21 away from the lifting member 25, the lifting lever 21 can lift the concrete foundation 100 with the second connecting member 24 as the lever fulcrum, eliminating the need for manual handling by construction workers, reducing their labor intensity, and improving construction efficiency. Furthermore, the lifting lever 21 can slide within the connecting sleeve 22, allowing construction workers to adjust the lever arm as needed, improving user comfort. Meanwhile, the second connecting piece 24 is movably connected to the first connecting piece 12 to adjust the distance between the lifting lever 21 and the wheel axle 13, so that the lifting piece 25 can lift concrete foundations 100 of different heights, thereby improving the versatility of the lifting and transportation device.

[0037] In this embodiment, each end of the axle 13 is interference-fitted with a bearing, and the outer ring of the bearing is interference-fitted with the shaft hole of the traveling wheel 14 to realize the rotational connection between the axle 13 and the traveling wheel 14, ensuring that the traveling wheel 14 travels on the factory roof and improving construction efficiency.

[0038] A support frame 11 is fixedly connected to the axle 13. This embodiment does not specifically limit the shape of the support frame 11. Exemplarily, the support frame 11 includes a support plate 111 and three support rods 112. The bottom ends of the three support rods 112 are fixedly connected to the axle 13, and the top ends of the three support rods 112 are fixedly connected to the support plate 111. The support plate 111 is fixedly connected to the first connecting member 12. The cooperation of the support rods 112 and the support plate 111 can reduce the weight of the support assembly 1. On the one hand, it can reduce the weight of the lifting and transporting device, ensuring that the lifting and transporting device can travel on the factory roof; on the other hand, it can save costs.

[0039] Specifically, see Figure 1 and Figure 3 The three support rods 112 are inclined, with their tops on the same plane and distributed at the three corner points of a triangle. This triangular arrangement of the support rods 112 improves the stability of the support plate 111, thereby enhancing the stability of the lifting and transporting of the concrete foundation 100 and improving construction quality.

[0040] The second connecting member 24 can move vertically relative to the first connecting member 12, thereby adjusting the lifting height of the lifting and transporting device and improving its versatility. Optionally, see [link to other documentation]. Figure 5 The first connector 12 has a sliding groove that extends along the length of the first connector 12. The second connector 24 can slide in the sliding groove, and the first connector 12 and the second connector 24 can be fixedly connected by the locking member 3. The second connector 24 is slidably connected in the sliding groove, which is convenient for adjustment.

[0041] Specifically, the sliding groove is a circular groove, which is easy to process, and the groove wall of the circular groove is smooth. The second connector 24 slides in the sliding groove, which can reduce the wear on the second connector 24 and improve the service life of the first connector 12 and the second connector 24.

[0042] Further, see Figure 5 The locking member 3 is a pin. The first connecting member 12 has two sets of first connecting holes 121 symmetrically arranged. Each set of first connecting holes 121 is spaced apart along the length of the first connecting member 12. All first connecting holes 121 are connected to the sliding groove. The second connecting member 24 has a second connecting hole 241 that can be aligned with the first connecting hole 121. The locking member 3 passes through the first connecting hole 121 and the second connecting hole 241 to fix the first connecting member 12 and the second connecting member 24. The operation is simple.

[0043] In use, simply move the second connector 24 to the designated height, rotate the second connector 24 so that the first connecting hole 121 of the first connector 12 is aligned with the second connecting hole 241 of the second connector 24, and insert the locking member 3 into the first connecting hole 121 and the second connecting hole 241 to fix the first connector 12 and the second connector 24. Specifically, limiting parts can be provided at both ends of the locking member 3 to prevent the locking member 3 from slipping away from the first connector 12 and / or the second connector 24, causing the first connector 12 and the second connector 24 to separate, preventing the concrete foundation 100 from falling onto the roof and reducing safety hazards.

[0044] Optionally, see Figure 6 The first connecting member 12 has a threaded hole extending along its length. The outer surface of the second connecting member 24 is threaded. The first connecting member 12 and the second connecting member 24 are threadedly connected and can rotate and rise. When rotated, the second connecting member 24 can move vertically, changing the lifting height of the lifting and transporting device. Simultaneously, the threaded connection has self-locking properties, preventing the first connecting member 12 and the second connecting member 24 from separating, thus improving safety.

[0045] In other embodiments, the second connector 24 may have a threaded hole that extends along the length of the second connector 24, and the outer surface of the first connector 12 may be provided with threads.

[0046] The connecting sleeve 22 can be threadedly connected to the lifting lever 21 or slidably connected. In this embodiment, the connecting sleeve 22 is slidably connected to the lifting lever 21, see [link to documentation]. Figure 4 The connecting sleeve 22 has two threaded holes 221 spaced apart along its axial direction. Both threaded holes 221 extend radially along the connecting sleeve 22. Each threaded hole 221 is connected to a fastener 23. When the fastener 23 rotates, it can move closer to or further away from the lifting lever 21. When it moves closer, the fastener 23 can press against the lifting lever 21. Due to the self-locking effect of the threads, the fastener 23 can fix the lifting lever 21 and the connecting sleeve 22 after pressing against the lifting lever 21. When the fastener 23 is separated from the lifting lever 21, the lifting lever 21 can slide inside the connecting sleeve 22, which facilitates the adjustment of the lever arm.

[0047] Since the fastener 23 can be pressed against any position of the lifting lever 21, the lifting lever 21 and the connecting sleeve 22 can be infinitely adjusted without being limited by preset gears. They can be flexibly adjusted according to the actual situation, making the adjustment simple and improving the adjustment accuracy, which further improves the comfort of construction personnel using the lifting and transportation device.

[0048] In this embodiment, see Figure 1 and Figure 2 The lifting component 25 includes a lifting rope 251 and a hook 252. The lifting rope 251 is fixedly connected to the lifting lever 21, and the hook 252 is connected to the bottom end of the lifting rope 251. The hook 252 can be connected to the lifting flange 101. By connecting the lifting lever 21 through the lifting rope 251, the elasticity of the lifting rope 251 can buffer the impact force during the lifting process and reduce the hard pulling on the lifting flange 101. At the same time, the hook 252 can quickly align with the connection point of the lifting flange 101 to achieve convenient loading and unloading. It can also adapt to different installation angles of the lifting flange 101 by the swing of the lifting rope 251, thereby improving the flexibility and safety of the lifting operation.

[0049] Optionally, the lifting rope 251 can be made of high-strength nylon braided rope, which has high tensile strength, can withstand hundreds of kilograms of weight, and can be bent for easy storage.

[0050] Specifically, the lifting rope 251 is equipped with multiple lifting rings, each of which can be fitted onto the lifting lever 21. Different lifting rings fitted onto the lifting lever 21 can change the lifting length of the lifting rope 251. Changing the lifting height of the rope can adapt to the height change of the lifting lever 21 caused by the relative movement of the first connecting member 12 and the second connecting member 24. This avoids the situation where the lifting rope 251 is not long enough when the lifting height increases, causing the hook 252 to be unable to connect to the lifting flange 101, or the lifting rope 251 is too long when the lifting height decreases, causing the rope to not be taut and thus unable to lift the concrete foundation 100.

[0051] To facilitate operation by construction personnel, in this embodiment, see [link to example]. Figure 1 and Figure 4 An operating handle 211 is provided at the end of the lifting lever 21 away from the lifting component 25, and the operating handle 211 is perpendicularly connected to the lifting lever 21. The outer surface of the operating handle 211 is covered with a cushioning layer to improve the grip comfort of the construction personnel. The cushioning layer can be a rubber sleeve.

[0052] The steps for using the lifting and transporting device provided by this utility model are as follows:

[0053] First, adjust the relative positions of the lifting lever 21 and the connecting sleeve 22 to facilitate operation by construction personnel, and then rotate the fastener 23 to fix the lifting lever 21 and the connecting sleeve 22.

[0054] Then, lift the end of the lifting lever 21 away from the lifting component 25, connect the hook 252 to the lifting flange 101, press down the end of the lifting lever 21 away from the lifting component 25, and lift the concrete foundation 100.

[0055] Finally, move the lifting and transport device to the designated position on the factory roof, place the concrete foundation 100, and separate the hook 252 and the lifting flange 101. Continue lifting the remaining concrete foundations 100 to the designated position.

[0056] It should be noted that the two lifting and transport devices can be used in conjunction during operation to improve work efficiency. Each lifting and transport device lifts one end of the concrete foundation 100, which can further reduce the labor intensity of construction workers and improve work efficiency. Furthermore, the coordinated operation of the two lifting and transport devices can also improve the stability of the concrete foundation 100 during transport.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
