Description

Technical Field

[0001] This utility model relates to the field of cylindrical rotary support technology, and in particular to a positionable rotary mechanism for large-diameter cylindrical bodies. Background Technology

[0002] Large-diameter cylinders are cylindrical structures used for the installation and support of wind turbines. During the production and processing of large-diameter cylinders, circumferential welding is required. Due to the long dimensions of the large-diameter cylinders, a slewing support mechanism is often needed for auxiliary slewing support. However, in existing large-diameter cylinder auxiliary slewing support mechanisms, the slewing wheel contacts the outer circle of the cylinder during slewing support, and there is a lack of positioning mechanism between the outer circle of the cylinder and the slewing wheel. During use, the cylinder is prone to relative positional movement on the slewing wheel, which can lead to deviations in the welding point. At the same time, the cylinder is prone to lateral movement during slewing operations on the slewing wheel. In severe cases, the cylinder may fall off the slewing wheel, causing production accidents. Therefore, the existing cylinder slewing support mechanism can no longer meet the production needs of enterprises. Utility Model Content

[0003] The main purpose of this invention is to provide a positioning and rotating mechanism for large-diameter cylinders. During rotation, the mechanism can limit the cylinder in the axial direction to prevent it from moving around. During welding, it can press the end of the cylinder to ensure the cylinder is in a stable position on the rotating wheel, effectively meeting the needs of welding and rotating operations for cylinders.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A positioning and rotating mechanism for a large-diameter cylindrical body includes a first support, a second support, a main rotating assembly, an auxiliary rotating assembly, a first positioning component, and a second positioning component. The first support and the second support are arranged at intervals on the working ground; the main slewing assembly is installed on the first support and connected to it; the auxiliary slewing assembly is installed on the second support and connected to it. A first positioning component is installed and connected to the side of the main rotating assembly, and a second positioning component is installed and connected to the side of the auxiliary rotating assembly. The first positioning component and the second positioning component work together to prevent the large-diameter cylinder from shifting and to clamp and position it. The main rotating assembly and the auxiliary rotating assembly work together to realize the rotation operation of the large-diameter cylinder.

[0005] The first positioning component and the second positioning component have the same structure, both including a cylinder bracket, a working cylinder, a pressing actuator, and a hinge bracket; the working cylinder is mounted on the cylinder bracket, a telescopic cylinder rod is mounted on the working cylinder, and an opening slot is provided on the hinge bracket; the tail end of the pressing actuator is rotatably connected to the upper part of the cylinder rod; the middle part of the pressing actuator is hinged in the opening slot on the hinge bracket.

[0006] The clamping actuator includes a connecting section, a working section, and a clamping block; the connecting section and the working section are fixedly connected as an integral structure, and the connecting section and the working section form a 135° angle; the tail of the connecting section is rotatably connected to the cylinder rod; and the contact parts of the connecting section and the working section are hinged to the hinge bracket; the clamping block is installed and fixedly mounted on the working section for clamping and positioning the large-diameter cylinder.

[0007] The main slewing assembly includes a left slewing wheel assembly, a right slewing wheel assembly, and a main support base; the bottom of the main support base is mounted on a first support and welded to the first support; a left slewing wheel assembly is mounted on one side of the upper part of the main support base, and a right slewing wheel assembly is mounted on the other side of the upper part of the main support base; the bottoms of the left slewing wheel assembly and the right slewing wheel assembly are connected to the main support base by bolts.

[0008] The left and right slewing wheel sets have the same structure, each including a working motor, a reducer, a main slewing wheel, and a main wheel frame. The working motor is installed at the power input end of the reducer to input rotational torque to the reducer. A drive shaft is connected to the power output end of the reducer. The drive shaft is mounted on the main wheel frame through bearings, and the main slewing wheel is coaxially fixedly mounted on the drive shaft.

[0009] The auxiliary slewing assembly includes a left auxiliary wheel set, a right auxiliary wheel set, and an auxiliary support base; the bottom of the auxiliary support base is fixedly mounted on a second support; the left and right auxiliary wheel sets are located on both sides of the auxiliary support base and are connected to the auxiliary support base by bolts; the second positioning component is located between the left and right auxiliary wheel sets and is connected to the auxiliary support base.

[0010] The left and right auxiliary wheel sets have the same structure, each including an auxiliary wheel frame, an auxiliary wheel body, and an auxiliary wheel axle. The bottom of the auxiliary wheel frame is connected to the auxiliary support base by bolts. The two ends of the auxiliary wheel axle are mounted on the auxiliary wheel frame by bearings, and the auxiliary wheel body is coaxially fixedly assembled on the auxiliary wheel axle.

[0011] The overall structural design of the positioning rotary mechanism for large-diameter cylinders in this utility model is scientific. Compared with the existing auxiliary rotary structures for cylinders, it can axially limit the cylinder during rotation to prevent it from moving around, and can also press the large-diameter cylinder during welding to ensure the accuracy of the weld position. Specifically, a first positioning component and a second positioning component are respectively installed on the middle outer side of the main rotary assembly and the auxiliary rotary assembly. When the cylinder moves around during rotation, the first positioning component and the second positioning component can block and limit the end of the cylinder. When the cylinder is being welded, the working cylinder can push the pressing actuator to rotate around the hinged bracket through the cylinder rod, so that the working end of the pressing actuator presses the inner wall of the large-diameter cylinder through the pressing block, and finally presses the cylinder onto the main rotary assembly and the auxiliary rotary assembly, effectively preventing the cylinder from moving around during the welding process.

[0019] The working process of the positioning and rotating mechanism for large-diameter cylindrical bodies of this utility model during specific installation and use is as follows: 1. First, the operator can use external hoisting equipment to hoist the large-diameter cylinder to be welded onto the main slewing assembly 3 and the auxiliary slewing assembly 4, ensuring that the main slewing wheel 313 in the main slewing assembly 3 and the auxiliary wheel 412 in the auxiliary slewing assembly 4 are in full contact with the outer circle of the cylinder, and ensuring that the main slewing wheel 313 and the auxiliary wheel 412 provide stable contact support for the cylinder; 2. At this time, the working motor 311 in the main rotating assembly 3 can be started. The working motor 311 inputs rotational torque into the reducer 312. The reducer 312 drives the drive shaft to rotate through its power output end. When the drive shaft rotates, it can drive the main rotating wheel 313 to rotate. At this time, under the action of contact friction, the cylinder supported by the main rotating wheel 313 and the auxiliary wheel 412 achieves rotation. 3. During the rotation of the cylinder, if the cylinder moves axially, the first positioning component 5 located between the left rotary wheel group 31 and the right rotary wheel group 32 and the second positioning component 6 located between the left auxiliary wheel group 41 and the right auxiliary wheel group 42 can contact and limit the end of the cylinder to prevent the cylinder from falling. 4. When the cylinder is rotated to the preset position, the operator can control the working cylinder 52 in the first positioning component 5 and the second positioning component 6 to start. The working cylinder 52 drives the cylinder rod to rise, and the cylinder rod pushes the connecting section 531 of the clamping actuator 53 to rise. At this time, the working section 532 and the clamping block 533 in the clamping actuator 53 press down. When the clamping block 533 is pressed against the bottom of the inner cavity of the cylinder, the working cylinder 52 stops working. At this time, the clamping actuator 53 in the first positioning component 5 and the second positioning component 6 presses the cylinder against the main rotating assembly 3 and the auxiliary rotating assembly 4. 5. At this time, the relative positions of the cylinder body, the main rotary wheel 313, and the auxiliary wheel body 412 are locked, and the operator can control the external welding equipment to perform welding operations on the outer periphery of the cylinder body, effectively ensuring the accuracy of the welding point.
