A feeding pipe anti-sway device

Abstract

This utility model discloses an anti-sway device for a feeding pipe, relating to the technical field of electrolytic aluminum feeding devices. It aims to solve the problem in existing technologies where gaps exist between the reinforcing plate and the rubber tube, causing swaying and friction in the rubber tube. The technical solution involves connecting an overhead crane to a base plate, with a main body slidably connected to the base plate. The main body is connected to a lifting mechanism, and a feeding pipe is rotatably connected below the main body. The feeding pipe and the feeding pipe are connected. A rotating support assembly is located on the feeding pipe, with sliding mechanisms on both sides of the rotating support assembly. The sliding mechanisms are connected to the base plate via a support frame, and anti-sway components are located on both sides of the sliding mechanisms. This utility model reduces the sway rate of the feeding pipe above and below through the slide rail, sliding mechanism, and rotating support assembly, thereby achieving anti-sway. Due to the presence of the slide rail, chute, guide plate, sliding plate, pulley, and pressure bearing, friction is greatly reduced during operation without any interference, allowing for long-term operation.

Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum feeding devices, specifically a feeding tube anti-sway device. Background Technology

[0002] Chinese patent CN114436111A discloses an anti-sway device for the rubber tube of a multi-functional electrolytic aluminum unit. The technical solution includes a flange with multiple reinforcing ribs fixed to the bottom of the flange. Multiple arc-shaped connecting ribs are fixed between two adjacent reinforcing ribs. Each reinforcing rib has an outwardly bent continuous bending part at the upper end. The rubber tube is limited by the reinforcing ribs, thereby achieving anti-sway.

[0003] This technical solution also has the following shortcomings: the stiffening plate limits the rubber tube to prevent swaying. Since the rubber tube needs to move up and down or rotate, there is a gap between the stiffening plate and the rubber tube. The gap will also cause the rubber tube to sway. Moreover, the rubber tube will inevitably interfere with and rub against the stiffening plate after a long time of movement or rotation. Even with the presence of a flexible pad, it is impossible to solve the risk of friction damage in the long term. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figures 1 to 10As shown, this utility model discloses a device for preventing the swaying of a discharge pipe. The technical solution includes an overhead crane with a lifting mechanism and a discharge pipe. The overhead crane is connected to a base plate 1, which has a slide rail 101. A slide groove 401 is formed on the main body 4. The base plate 1 and the main body 4 are slidably connected through the slide rail 101 and the slide groove 401. The main body 4 is connected to the lifting mechanism, allowing it to slide up and down. A discharge pipe 5 is rotatably connected below the main body 4. The outer wall of the discharge pipe 5 has teeth 501. A reduction motor 8 is located above the main body 4. A gear 402 is on the output shaft of the reduction motor 8. The gear 402 meshes with the teeth 501, allowing the discharge pipe 5 to rotate. The discharge pipe 5 has a discharge port 502 on its lower side, and a recess 503 below the discharge port 502. When material accumulates inside the recess 503, it can prevent wear and tear on the bottom of the discharge pipe 5 due to prolonged discharge. The discharge pipe 5 is connected to the feed pipe. The discharge pipe 5 has a rotating support assembly 7, which includes an annular groove 504. The annular groove 504 is integrated with the discharge pipe 5. Below the annular groove 504 is a support plate 701, and on the support plate 701 is a baffle 702. Inside the annular groove 504 on the left side of the baffle 702 is a pressure bearing 9. During descent, the top of the annular groove 504 will press tightly against the top of the pressure bearing 9. Above the annular groove 504 is a flange 703. The flange 703 and the support plate 701 are connected by the fixing bolts 10, and there is a gap between the flange 703 and the annular groove 504. The diameter of the flange 703 is smaller than that of the support plate 701 and it does not contact the guide plate 301. The rotating support assembly 7 has sliding mechanisms 3 on both sides. The support frame 2 is provided with a rotating shaft 201. The sliding mechanism 3 includes a guide plate 301 and a sliding plate 302. The guide plate 301 and the sliding plate 302 are L-shaped plates. The guide plate 301 is rotatably connected to the rotating shaft 201. The rigid connection is prone to deformation of the guide plate 301 and the sliding plate 302 during long-term operation. The sliding plate 302 is located inside the guide plate 301. A pulley 303 is provided on 302. The guide plate 301 and the sliding plate 302 are slidably connected by the pulley 303. The sliding plate 302 is fixedly connected to the support plate 701. There are anti-sway components 6 on both sides of the sliding mechanism 3. The anti-sway components 6 include a support plate 601 and an adjusting plate 602. The adjusting plate 602 is located inside the support plate 601. The support plate 601 is fixed to the base plate 1. A sliding shaft 3011 is provided on the back of the guide plate 301. The sliding shaft 3011 penetrates the support plate 601 and the adjusting plate 602. There is a spring 603 between the adjusting plate 602 and the guide plate 301. An adjusting bolt 604 is screwed on the support plate 601. The end of the adjusting bolt 604 contacts the adjusting plate 602.

[0026] The working principle of this utility model is as follows: When using this device, it is first moved to the working position by a crane, and then the main body 4 is lowered by a lifting mechanism, thereby controlling the discharge port 502 to descend. The main body 4 moves up and down on the base plate 1 through the slide groove 401 and the slide rail 101 to achieve the stability of the upper end of the discharge pipe 5. The lower end of the discharge pipe 5 is connected to the sliding mechanism 3 through the rotating support assembly 7. The sliding mechanism 3 is connected to the base plate 1 through the support frame 2. When the spring 603 pushes the sliding mechanism 3 inward and lowers it, the sliding plate 302 slides on the guide plate 301 synchronously, thereby achieving the stability of the lower end of the discharge pipe 5. When the discharge port 502 needs to change its angle, the reduction motor 8 is controlled to rotate, and the gear 402 rotates synchronously with the output shaft of the reduction motor 8, driving the discharge pipe 5 to rotate. The pressure bearing 9 below assists in the rotation, thereby achieving stable angle adjustment of the discharge port 502. The amount of swing of the lower end of the discharge pipe 5 can be adjusted by adjusting the adjusting bolt 604 to change the force between the spring 603 and the sliding mechanism 3.
