Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a lifting equipment for electric hoisting of fully prefabricated box culverts. Background Technology

[0002] A fully precast box culvert is a box-shaped culvert structure manufactured using precast concrete component technology. It is precast in a factory and then transported to the construction site for assembly. This can greatly reduce on-site construction time and space occupation, reduce the impact on the surrounding environment, and improve the precision and quality of components and enhance the durability of the structure due to factory production.

Figure 1-6As shown: A lifting device for electric hoisting of fully prefabricated box culverts includes: a fixed base 1; a winding part 2 disposed at the bottom of the fixed base 1; and a clamping part 3 disposed inside the winding part 2; wherein the winding part 2 includes: a rotating base 211, fixedly connected to the bottom of the fixed base 1; and a connecting frame 212, rotatably connected to the bottom of the rotating base 211.

[0019] The outer wall of the connecting frame 212 is provided with a transmission port, which is equidistant from each other around the circumference.

A sliding frame 220 is fixedly connected to the output end of the reciprocating electric telescopic column 221. The sliding frame 220 is slidably connected between the inner sides of the guide frame 219. The sliding frame 220 is adapted to the pressure sensor 222. The reciprocating electric telescopic column 221 is electrically connected to the pressure sensor 222.

[0022] Furthermore, in this embodiment, during use, the electric rotating column 216 is driven to rotate, thereby turning out the entire connecting cable 312. Due to the multiple settings of the winding section 2, it is convenient to clamp the workpiece at multiple support points. Conversely, when not in use, the electric rotating column 216 is driven to rotate, winding up the connecting cable 312, and the reciprocating electric telescopic column 221 is driven, so that the sliding frame 220 at the telescopic end of the reciprocating electric telescopic column 221 slides along the trajectory of the guide frame 219.

Figure 1-6As shown: The clamping part 3 includes: a fixing ring 311, which is fixedly connected to the outer wall of the electric rotating column 216; and a connecting cable 312, which is fixedly connected to the outer wall of the fixing ring 311.

[0024] One end of the connecting iron cable 312 extends outward through the sliding frame 220. One end of the connecting iron cable 312 is fixedly connected to the connecting seat 313. The bottom end of the connecting seat 313 is rotatably connected to the U-shaped clamping frame 314. The bottom of the U-shaped clamping frame 314 has a sliding opening, which is symmetrically arranged. The bottom of the U-shaped clamping frame 314 has a threaded opening.

[0026] Furthermore, in this embodiment, the U-shaped clamping frame 314 is placed on one side of the workpiece, and then the threaded rod 317 is rotated to make it rotate and slide upward. Under the action of the guide post 315, the sliding of the clamping plate 316 is limited, thereby achieving the purpose of clamping the workpiece. Due to the multiple settings of the clamping part 3, the purpose of clamping the workpiece at multiple support points is achieved, thereby improving the stability of the transfer.

[0027] In use, firstly, the electric rotating column 216 is driven to rotate, thereby fully extending the connecting cable 312. Due to the multiple configurations of the winding section 2, it is convenient to clamp the workpiece at multiple fulcrums. Conversely, when no longer in use, the electric rotating column 216 is driven to rotate, winding up the connecting cable 312 and driving the reciprocating electric telescopic column 221, causing the sliding frame 220 at the telescopic end of the reciprocating electric telescopic column 221 to slide along the trajectory of the guide frame 219. When the sliding frame 220 touches the pressure sensor 222 on one side, it controls the sliding frame 220 to change direction. The sliding direction is changed to control the reciprocating sliding of the sliding frame 220, thereby achieving uniform winding of the connecting iron cable 312 and preventing the connecting iron cable 312 from tangling; secondly, the U-shaped clamping frame 314 is placed on one side of the workpiece, and then the threaded rod 317 is rotated to make it rotate upward, and under the action of the guide post 315, the sliding of the clamping plate 316 is limited, thereby achieving the purpose of clamping the workpiece. Due to the multiple settings of the clamping parts 3, the workpiece is clamped at multiple support points, thereby improving the stability of the transfer.
