[0002] Precast culvert sections, also known as precast concrete culvert pipes or prefabricated culvert components, refer to standardized, modular concrete or reinforced concrete pipe sections or box sections that are prefabricated in a factory. These components are transported to the construction site and assembled like building blocks to quickly form underground structures such as culverts, pipelines, and passageways. These structures require the use of hoisting and rotating frames during construction.

[0003] Existing hoisting rotating frames consist of a frame, boom, claws, and a rotating mechanism. The rotating mechanism is connected to the boom and drives the claws to rotate, thereby adjusting the installation and docking angle of the precast culvert sections.

The hoisting mechanism is connected to the top of the multiple sets of connecting rods 101 and the closing block 102. It should be noted that the structural strength of the lifting frame 1 is enhanced by the closing block 102 and the connecting rod 101, and the connection points of the lifting mechanism are provided. This scheme adopts two sets of boom 4 structures, which are symmetrically welded to both ends of the lifting frame 1 along the center.

[0021] Multiple sets of booms 4 are symmetrically fixedly connected to the bottom of both ends of the lifting frame 1. Each set of booms 4 is provided with a claw 8 on the opposite side. Both ends of the lifting frame 1 are fixedly connected with baffles 103. The middle of each set of booms 4 is fixedly connected with a reinforcing rod 401. The reinforcing rod 401 is used to improve the structural strength of the booms 4. Under the suspension support of the booms 4, the claws 8 clamp and grab the precast culvert section by intersecting with it. Specifically, the lifting mechanism includes: Mounting block 2 is fixedly connected to the top of closing block 102, and mounting hole is provided on the top of mounting block 2; Hanging plate 3, multiple sets of hanging plates 3 are respectively fixedly connected to the top of multiple sets of connecting rods 101, and each set of hanging plates 3 has a hanging hole on its top.

[0022] It should be noted that the entire hoisting rotating frame can be connected to the lifting equipment through the mounting block 2 and the lifting plate 3. In this way, the precast culvert section can be picked up by the hoisting rotating frame and then transferred by the lifting equipment.

[0023] Example 2: This utility model provides the following... Figure 3 The rotating mechanism shown is applied to a precast culvert section hoisting rotating frame mechanism in Embodiment 1. The rotating mechanism is located at the bottom of the boom 4 at one end. Specifically, a support plate 6 is fixedly connected to the bottom of one end of the boom 4, and a rotating mechanism is set at the top of the support plate 6. A support column 5 is rotatably connected to the bottom of the other end of the boom 4. The rotating mechanism includes a rotary motor 7, which is fixedly connected to the top of the support plate 6. An output rod 701 is driven to the output end of the rotary motor 7.

[0024] It should be noted that the housing of the rotary motor 7 is fixedly connected to the top of the support plate 6, and a speed reducer structure is provided at the output end of the rotary motor 7. The output rod 701 is connected to the output end of the speed reducer, thereby completing the power output transmission of the rotary motor 7.

[0025] Example 3: This utility model provides the following... Figure 4 The quick-release mechanism shown is applied to a precast culvert section hoisting rotating frame mechanism in Embodiment 1 and a rotating mechanism in Embodiment 2. Multiple quick-release mechanisms are respectively arranged on opposite sides of multiple sets of booms 4. One end of each set of quick-release mechanisms is fixedly connected to the middle of multiple sets of claws 8. Multiple quick-release mechanisms are detachably connected to booms 4 and rotating mechanisms respectively. Output rod 701 and support column 5 are detachably connected to multiple sets of quick-release mechanisms respectively. Specifically, the quick-release mechanism includes: Connecting pipe 9 is sleeved on the outer wall of output rod 701 or support column 5; Connecting rod 901, one end of multiple sets of connecting rods 901 passes through connecting pipe 9 and is inserted and connected to output rod 701 or support column 5.

[0026] It should be noted that the inner wall of the connecting tube 9 is adapted to the outer wall of the output rod 701 and the support column 5. The connecting tube 9 can fit snugly on the outer wall of the output rod 701 and the support column 5. One end of the connecting rod 901 has the outer wall of the connecting tube 9 passing through it and being inserted into its middle. The outer wall of the output rod 701 and the support column 5 are provided with mating holes. One end of the connecting rod 901 passing through the connecting tube 9 is inserted and connected to the mating hole. In this way, the connecting tube 9 connected to the output rod 701 rotates synchronously with it, and the connecting tube 9 connected to the support column 5 is used for rotational support.

[0027] Furthermore, a pull plate 902 is fixedly connected to the other end of the connecting rod 901. A blocking groove is provided at the intersection of the connecting rod 901 and the connecting tube 9. A blocking slider 903 is fixedly connected to the outer wall of the connecting rod 901.

[0028] It should be noted that by setting and cooperating with the blocking slider 903 and the blocking groove, the connecting rod 901 will not detach from the connecting tube 9. Furthermore, by using the compression of the top support spring 904 and the blocking slider 903, the blocking slider 903 will always drive the connecting rod 901 to pass through towards the core of the connecting tube 9, thereby ensuring the stable connection between the entire quick-release mechanism, the output rod 701, and the support column 5.
