Description

Technical Field

[0001] The utility model relates to the field of flange processing and fixing devices for large-span steel pipe towers, and specifically relates to a flange processing and fixing device for large-span steel pipe towers. Background Technique

[0002] A large-span steel pipe tower is a high tower structure used for power lines or communication lines, and it usually needs to withstand strong winds and other environmental factors. Using flange connection is a method to ensure the stability and safety of the tower structure. A flange is a disc-shaped component, usually used at the ends of pipelines, pipe fittings, valves, etc. for easy connection and fixation.

[0003] In the prior art, during the processing of flange plates, a fixing device is required to clamp and fix flange plates of a certain specification to prevent the flange from shifting during processing.

[0004] However, during the drilling process of the flange plate, it is often necessary to rotate the flange plate to adjust the position of the drilling. The existing fixing devices have a single function and cannot directly rotate the flange plate. It is necessary to first remove the flange plate, then manually adjust the position and clamp it again, which is time-consuming and laborious, with troublesome operation, low work efficiency, and very inconvenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flange processing and fixing device for large-span steel pipe towers to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a fixing table, a motor slot is opened in the middle of the top of the fixing table, a motor is arranged in the motor slot, a rotating shaft is inserted at the bottom of the motor, and a holding plate is connected to the top of the rotating shaft; and a sliding block, a clamping ring is arranged inside the sliding block, a communication slot is opened in the middle of the clamping ring, the communication slot communicates with a second telescopic slot opened inside the rear end of the clamping ring, and a plugging plate is inserted in the second telescopic slot.

[0007] Preferably, the motor can control the rotation of the rotating shaft, so that the rotating shaft drives the flange plate placed on the holding plate to rotate together to adjust the drilling position of the flange plate.

[0008] Preferably, first telescopic slots are opened around the holding plate, first springs are arranged in the first telescopic slots, the first springs can drive the sliding blocks to slide in the first telescopic slots, the inner sides of the first springs are connected to the sliding blocks, and a clamping ring is arranged inside the sliding blocks, and the clamping ring can clamp the edge of the flange plate.

[0009] Preferably, an adjusting screw rod is arranged in the middle of the top of the clamping ring. The bottom of the adjusting screw rod is connected with a pressing plate. By screwing the adjusting nut on the adjusting screw rod, the adjusting screw rod can drive the pressing plate to descend, and the flange clamped in the clamping ring is pressed and fixed.

[0010] Preferably, a second telescopic groove is formed inside the rear end of the sliding block. The bottom of the second telescopic groove penetrates through the sliding block. Second springs are arranged on both sides of the top of the adjusting screw rod. The bottom of the second spring is connected with a plugging plate, and the second spring can drive the plugging plate to expand and contract in the second telescopic groove.

[0011] Preferably, a plurality of slot holes are formed at the bottom of the first telescopic groove. The rear end of the pressing plate is plugged in the communicating groove and then plugged in the second telescopic groove through the communicating groove, and is clamped on the top of the plugging plate. When the communicating groove descends, the rear end of the communicating groove can extrude the second spring, so that the second spring extends out of the second telescopic groove and is plugged into the slot hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] A flange processing and fixing device for a large-span steel pipe tower proposed by the utility model. When processing the flange for the large-span steel pipe tower, first insert the four peripheral edges of the flange into the clamping ring. According to the diameter of the flange, the flange starts to extrude the sliding block at the rear end of the clamping ring, so that the first spring drives the sliding block to expand and contract backward to adapt to flanges of different specifications. Then, by screwing the adjusting nut on the adjusting screw rod at the top of the clamping ring, the adjusting screw rod drives the pressing plate to descend, and the four peripheral edges of the flange are fixed in the clamping ring. At the same time, when the pressing plate descends, the rear end of the pressing plate starts to extrude the plugging plate in the second telescopic groove through the communicating groove, so that the plugging plate extends out from the bottom of the second telescopic groove and is plugged into the corresponding slot hole to fix the sliding of the sliding block, preventing the first spring from driving the sliding block to slide during the processing of the flange, resulting in unstable clamping.
