Description

Technical Field

[0001] The utility model relates to the technical field of sootblower production, in particular to the technical field of a sootblower rotary assembly frame. Background Art

[0002] A sootblower is a device used to remove soot accumulated on the heating surfaces of a boiler. Over time, a thick layer of dust will condense on the boiler's inner walls. This dust can affect the boiler's thermal conductivity and, consequently, its heating effect. A sootblower can remove this dust by using sound waves or steam, ensuring proper heating and heat conduction.

[0003] Due to its structural characteristics, the steam soot blower needs to be turned back to the right position using a crane and a forklift after assembly, and then packed and boxed. Since the steam soot blower is long and heavy, there are great safety hazards when turning it back to the right position. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sootblower rotary assembly frame, which realizes rapid positioning and clamping before assembly. After assembly, the sootblower can be directly rotated on the device to turn it back to the right position and then packed, thereby improving work efficiency and greatly reducing safety hazards.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The sootblower rotary assembly frame includes a vertical frame, a shell, a telescopic table, a C-shaped seat, a pull ear, a connecting piece, a flip piece and a secondary positioning lever. The shell is provided with an upward-opening mounting groove, and the shell is rotatably mounted on a pair of vertical frames via a first rotating shaft. A motor is fixedly mounted on the vertical frame, and the output shaft of the motor is transmission-connected to the first rotating shaft. A first cylinder is fixedly mounted in the mounting groove, and the telescopic table is fixedly mounted on the telescopic rod of the first cylinder and movably placed in the mounting groove. The telescopic table has a hollow chamber, and a second cylinder is fixedly mounted in the chamber. The paired C-shaped seats are respectively fixedly mounted on both sides of the upper end of the telescopic table, and the C-shaped seats are open outward. The paired C-shaped seats are arranged in a row at the upper end of the telescopic table. A pin is fixedly mounted in the C-shaped seat, and a through slot corresponding to the notch of the C-shaped seat is provided at the upper end of the telescopic table. The pull ear is in the shape of a door. The cam is fixedly mounted on the extension pin of the second extension pin, and the cam is fixedly mounted on the extension pin of the second extension pin.

[0007] Preferably, the telescopic platform has a T-shaped structure.

[0008] Preferably, the lower end of the guide groove is inclined outward.

[0009] The connecting block is arranged above the guide groove of the inclined section.

[0010] The beneficial effects that can be achieved by the above technical solutions of the present invention are:

[0011] 1. By setting up a rotatable and liftable assembly table, it can be rotated 180 degrees after assembly is completed, turned back to the original position, and can be lifted and lowered to place in the packaging box, which improves work efficiency and reduces safety hazards.

[0012] 2. A through slot is opened at the upper end of the telescopic table, a pin is fixedly installed on the C-shaped seat, and the pulling ear is movably inserted into the pin through the guide slot. The pulling ear is movably hinged to the second cylinder. When the telescopic rod of the second cylinder is extended, the pulling ear moves upward, and the guide slot flips the pulling ear outward under the joint action of the pin and the connecting block. When the telescopic rod of the second cylinder is retracted, the pulling ear moves downward, and the guide slot moves the pulling ear downward to clamp the workpiece, thereby realizing the clamping and release of the workpiece.

[0013] 3. By rotating the flip plate through the second rotating shaft and installing it on the positioning block, the secondary positioning block rod is movably inserted into the flip plate through the first sliding groove, and a nut is engaged and installed on the screw rod. Before starting work, the flip plate and the pull ear are flipped outward, and the first workpiece is placed according to the positioning block. At this time, the second cylinder is started, the pull ear clamps the first workpiece, and then the flip plate and the secondary positioning block rod are flipped inward, and the second workpiece is placed according to the secondary positioning block rod, thereby realizing rapid positioning of the workpiece and greatly improving work efficiency.
