Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a prefabricated pipe pile lifting device. Background Art

[0002] At the foundation pit construction site, a crane is needed to lift the prefabricated pipe piles to the installation location. The current crane is generally composed of an electric hoist, a lifting rope and a hook. When lifting, the hook is fixed to the side of the pipe pile, and the crane lifts the pipe pile and completes the transfer. Since the pipe pile is heavy and usually needs to be lifted to a height of tens of meters, the inertia generated by the pipe pile during the lifting process is large, so the pipe pile is very easy to shake, and in severe cases, collisions or even falling off may occur.

[0003] Therefore, in order to control the inertia of pipe piles in the air, we developed this crane. The cage structure can control the direction of the pipe piles and greatly weaken the inertial shaking of the pipe piles, so that the pipe piles can run smoothly when lifted at high altitudes without collision or falling off.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the utility model provides a technical solution: a prefabricated pipe pile lifting device, comprising two groups of large frames 1 arranged in parallel, the two groups of large frames 1 are arranged in parallel, and the left and right sides are coordinated to ensure that the two groups of traveling seats 3 move synchronously, a plurality of groups of movable traveling wheels 2 are arranged at the bottom of the large frame 1, and a traveling seat 3 is slidably installed on the top of the large frame 1, and the traveling seat 3 is driven to move by an external power (not shown in the figure).

[0024] like Figure 1-2 As shown, a rotatable first winding shaft 4 is installed on the top of the walking seat 3, and the first winding shaft 4 is driven by an external first motor 5. A traction rope 8 is wound around the first winding shaft 4, and a cage 6 is installed at the bottom of the walking seat 3. The cage 6 is a multi-section telescopic structure, which is mainly to accommodate the lifting of the pipe pile to different heights. Therefore, the cage 6 needs to have sufficient length when fully unfolded and also be easy to store.

[0025] like Figure 2 As shown, a liftable traction rod 7 is slidably installed in the cage body 6, the top of the traction rod 7 is connected to the end of the traction rope 8, a slide groove 9 is opened on the inner wall of the cage body 6, a slide shaft 10 is installed in the slide groove 9, and both sides of the traction rod 7 are slidably installed on the slide shaft 10 through a sliding sleeve 16.

[0026] like Figure 1 As shown, a pick-up claw 11 that can be opened and closed is installed at the bottom of the traction rod 7.

[0027] like Figure 3 As shown, an auxiliary fixing mechanism is also provided at the bottom of the traction rod 7, and the auxiliary fixing mechanism includes a rotatable second winding shaft 12, and the second winding shaft 12 is driven by an external second motor 13. A fixing rope 14 is wound around the second winding shaft 12, and a fixing clamp 15 is connected to the end of the fixing rope 14. The fixing clamp 15 includes an upper clamp block 151 and a lower clamp block 152. The upper clamp block 151 and the lower clamp block 152 are connected by a threaded rod 153, and a locking nut 154 is provided on the threaded rod 153. By placing the upper clamp block 151 and the lower clamp block 152 at the height of the port of the pipe pile respectively and fixing them by the locking nut 154, the purpose of auxiliary fixing of the pipe pile is achieved, and the fixing rope 14 can be freely stretched to adapt to different distances.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0029] When in use, the first motor 5 is turned on, and the traction rod 7 is lowered by the traction rope 8 under the action of gravity, and the pipe pile is fixed by the picking claw 11 at the bottom of the traction rod 7. Further, the fixing clamp 15 is fixed at the two ports of the pipe pile.

[0030] Then the first motor 5 drives the traction rope 8 to be reeled in, thereby driving the pipe pile to rise into the air. Due to the restraining effect of the cage body 6, the traction rod 7 can only move in the vertical direction, so that the pipe pile can only be lifted and lowered vertically. During the lifting process, the pipe pile is continuously subject to the restraining force in the vertical direction, so it is difficult for it to shake, thereby ensuring the stability of the lifting.

[0031] In summary, the prefabricated pipe pile lifting device can control the direction of the pipe pile through the cage structure, that is, the pipe pile can only move in the vertical direction under the constraint of the cage structure, and cannot move horizontally, which greatly weakens the inertial shaking of the pipe pile, so that the pipe pile can run smoothly during high-altitude lifting without collision or falling off. Furthermore, by setting up an auxiliary fixing mechanism, a double insurance purpose is achieved, so that even if the picking claw fails, the auxiliary fixing mechanism can assume the temporary "picking claw" function to ensure normal lifting.

[0032] It should be noted that the electrical components appearing in this article are all connected to the external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device for controlling computers, etc. Its control principle, internal structure and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration.
