Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a hoisting structure of a precast concrete pipe pile. Background Art

[0002] Precast concrete pipe piles are a type of building component commonly used in infrastructure construction at this stage. They have the characteristics of high bearing capacity, quick and convenient construction, low environmental pollution, reliable pile quality, and good comprehensive technical and economic benefits, and have been widely promoted and used.

[0003] Precast concrete pipe piles are lifted by cranes during production, transportation and lifting. However, in the prior art, the existing method is to use a steel wire rope of a traveling crane to move the piles. A pair of hooks are provided on the steel wire rope of the traveling crane, and the hooks are fixed to the ports at both ends of the precast concrete pipe piles. The piles are then moved by the traveling crane. However, the hooks are easy to slip off the precast concrete pipe piles, which poses a great safety hazard and thus needs further improvement. Utility Model Content

[0004] In order to improve the safety of hoisting of precast concrete pipe piles, the present application provides a hoisting structure for precast concrete pipe piles.

[0005] The present application provides a prefabricated concrete pipe pile hoisting structure that adopts the following technical solution:

[0006] A lifting structure for precast concrete pipe piles, comprising a lifting base for placing the precast concrete pipe piles, the lifting base having a sliding cavity, two sliding cavities being arranged and distributed along the length direction of the lifting base, a movable plate being slidingly connected in each sliding cavity, the movable plate being fixedly connected to a guide rod slidingly penetrated by the lifting base, an end of the guide rod away from the movable plate being fixedly connected to a clamping plate externally arranged on the lifting base, the clamping plate being fixedly connected to a limiting plug correspondingly inserted into a port of the precast concrete pipe pile, and the lifting base being provided with an adjusting component for driving the two movable plates to slide toward or away from each other.

[0007] By adopting the above technical solution, after the precast concrete pipe pile is placed on the lifting base, the two movable plates are driven toward each other through the adjustment component, thereby driving the two clamping plates to slide toward the end of the precast concrete pipe pile and abut against the end face of the precast concrete pipe pile. In addition, the limit plug column is inserted into the port of the precast concrete pipe pile, so as to clamp and fix the two ends of the concrete pipe pile, and the lifting base is lifted by the lifting equipment to improve the lifting safety of the precast concrete pipe pile.

[0008] Preferably, the adjustment assembly includes an adjustment screw rotatably connected to the sliding cavity and a driving component for driving the adjustment screw to rotate, the axial direction of the adjustment screw is parallel to the axial direction of the guide rod, and the adjustment screw thread is penetrated through the movable plate.

[0009] By adopting the above technical solution, the adjusting screw is driven to rotate by the driving component, and the movable plate slides along the axial direction of the adjusting screw due to the thread restriction of the adjusting screw.

[0010] Preferably, the lifting base has a driving cavity located between the two sliding cavities, and one end of the adjusting screw extends into the driving cavity. The driving component includes a rotating shaft rotatably connected to the driving cavity, a first bevel gear built into the driving cavity and coaxially fixed on the rotating shaft, and a second bevel gear built into the driving cavity and coaxially fixed on the end of the adjusting screw, and the first bevel gear and the second bevel gear are meshed.

[0011] By adopting the above technical solution, the first bevel gear is driven to rotate by rotating the rotating shaft, so that the adjusting screw rod is synchronously rotated by the second bevel gear, thereby realizing the sliding movement of the two clamping plates.

[0012] Preferably, the lifting base is fixedly connected with a driving motor for driving the rotating shaft to rotate.

[0013] By adopting the above technical solution, the rotating shaft is driven to rotate by the driving motor, thereby realizing the electric operation of the clamping plate.

[0014] Preferably, the end of the rotating shaft away from the first bevel gear is fixedly connected to a handwheel externally disposed on the lifting base.

[0015] By adopting the above technical solution, the staff can rotate the shaft by turning the hand wheel, which is convenient for manual operation.

[0016] Preferably, the lifting base is provided with a limiter for limiting the rotation of the hand wheel.

[0017] By adopting the above technical solution, a limiting member is added to limit the rotation of the hand wheel, thereby improving operational safety.

[0018] Preferably, the limiting member is a limiting bolt threadedly connected to the handwheel, and the end face of the limiting bolt is pressed against the outer side wall of the lifting base.

[0019] By adopting the above technical solution, when the rotating shaft needs to be rotated, the limit bolt is loosened so that the end face of the limit bolt is separated from the outer wall of the lifting base, thereby releasing the rotation restriction of the hand wheel. After the clamping plate is adjusted, the limit bolt is tightened so that the end face of the limit bolt is pressed against the outer wall of the lifting base, thereby limiting the rotation of the hand wheel through damping.

[0020] Preferably, the clamping plate is provided with an elastic pad abutting against the end surface of the precast concrete pipe pile.

[0021] By adopting the above technical solution, the clamping plate is additionally provided with an elastic pad, thereby reducing the possibility of direct rigid contact between the clamping plate and the precast concrete pipe pile.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. After placing the precast concrete pile on the hoisting base, the two movable plates are driven to approach each other through the adjustment component, thereby driving the two clamping plates to slide toward the end of the precast concrete pile and abut against the end surface of the precast concrete pile. In addition, the limit plug is inserted into the port of the precast concrete pile, so as to clamp and fix the two ends of the concrete pile. The hoisting base is hoisted by the hoisting equipment to improve the hoisting safety of the precast concrete pile.

[0024] 2. The clamping plate is equipped with an elastic pad to reduce the possibility of direct rigid contact between the clamping plate and the precast concrete pipe pile. BRIEF DESCRIPTION OF THE DRAWINGS
