Description

Technical Field

[0001] This utility model relates to the structural technology of exhaust pipe connection components, specifically to a novel exhaust pipe connection component for a turbine main unit. Background Technology

[0002] The exhaust pipe of the turbine is responsible for safely and efficiently discharging the high-temperature exhaust gas after power is applied. It must be resistant to high temperature and corrosion, and be able to withstand the high temperature and pressure impact of the exhaust gas. Its reasonable pipe diameter and routing design can reduce exhaust resistance, improve the efficiency of the turbine, reduce noise, and ensure stable operation of the equipment.

[0003] When welding the exhaust pipes of two turbine main units, manual support is usually used. However, if the operator makes a mistake, the exhaust pipe may shake. Once the exhaust pipe shakes, it will not only affect the welding quality, but also cause defects such as porosity and cracks in the weld, creating safety hazards. Therefore, there is an urgent need for a new type of exhaust pipe connection component for turbine main units to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel exhaust pipe connection assembly for a turbine main unit to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel exhaust pipe connection assembly for a turbine main unit includes two exhaust pipe bodies. Two arc-shaped plates are slidably connected to the surfaces of both exhaust pipe bodies. Two second bolts are slidably connected inside the arc-shaped plates. Eight second bolts are arranged in pairs. A connecting bracket is threaded onto the surface of each pair of second bolts. A locking hole is formed on the surface of the connecting bracket. A square plate is slidably connected to the inner wall of the locking hole. The surface of the square plate is fixedly connected to the arc-shaped plate. Locking grooves are formed on the surfaces of both connecting brackets. Eight locking grooves are arranged in pairs. A first bolt is slidably connected to the inner wall of each pair of locking grooves. A fixing cylinder is threaded onto the surface of the first bolt. Four connecting brackets are arranged in groups of four. Two bearing rods are fixedly inserted inside each group of connecting brackets. The effect of this component is that it can limit the movement of the two turbine main unit exhaust pipes during welding, preventing workers from welding the two turbine main unit exhaust pipes together and causing the turbine main unit exhaust pipes to shake, thus avoiding safety hazards caused by shaking.

[0007] Preferably, anti-slip pads are fixedly installed on the surfaces of all eight second bolts. The anti-slip pads are rubber pads. The effect achieved by the above components is that the anti-slip pads can increase the friction between the second bolts and the exhaust pipe.

[0008] Preferably, anti-detachment blocks are fixedly installed on the inner walls of all eight slots. The effect achieved by the above components is that the anti-detachment blocks can assist the first bolt in fixing the connecting frame.

[0009] Preferably, an auxiliary plate is fixedly installed on the surface of each of the four first bolts, and the surface of the auxiliary plate abuts against the anti-loosening block. The effect achieved by the above components is that the auxiliary plate can prevent the first bolt from sliding out of the inner wall of the slot.

[0010] Preferably, each of the four square plates has a contact ball fixedly installed at the end away from the arc plate. The size of the contact ball is larger than the size of the locking hole. The effect achieved by the above components is that the contact ball can prevent the square plate from sliding out of the inner wall of the locking hole, thereby achieving the effect of restricting the square plate from sliding out of the inner wall of the locking hole.

[0011] Preferably, two positioning frames are fixedly installed on the surface of each of the four connecting frames. A balance block is slidably connected to the surface of the positioning frame. The surface of the balance block is fixedly connected to the connecting frame. The cross-section of the balance block is "T". The effect achieved by the above components is that the positioning frame and the balance block can help the worker to align the two connecting frames.

[0012] Preferably, the inner walls of the four slots are provided with rounded corners. The effect achieved by the above components is that the rounded corners can help the operator insert the first bolt into the inner wall of the slot.

[0013] In the above technical solution, this utility model provides a novel exhaust pipe connection assembly for a turbine main unit.

[0014] (1) By setting up components such as connecting frame, bearing rod and arc plate, the exhaust pipes of the two turbine main units can be limited when welding the exhaust pipes of the two turbine main units, preventing the workers from welding the exhaust pipes of the two turbine main units together and causing the exhaust pipes of the turbine main units to shake, thus avoiding the safety hazards caused by shaking.

[0015] (2) By setting up components such as positioning frames and balance blocks, it is convenient for workers to align the two connecting frames when connecting them, so as to make it convenient for workers to fix the two connecting frames together. Attached Figure Description

Two arc plates 11 are slidably connected to the surfaces of both exhaust pipe bodies 1. Two second bolts 13 are slidably connected inside the arc plates 11. Eight second bolts 13 are grouped in pairs. A connecting bracket 2 is threadedly connected to the surface of each group of second bolts 13. A locking hole 14 is provided on the surface of the connecting bracket 2. A square plate 12 is slidably connected to the inner wall of the locking hole 14. The surface of the square plate 12 is fixedly connected to the arc plates 11. The surfaces of the two connecting brackets 2 are... The device has eight slots 6, arranged in pairs. Each pair of slots 6 has a first bolt 4 slidably connected to the inner wall of its inner wall. The first bolt 4 has a fixed cylinder 5 threadedly connected to its surface. The device also has eight connecting brackets 2 arranged in groups of four. Each connecting bracket 2 has two bearing rods 3 fixedly inserted inside its inner wall. The effect of the above components is that they can limit the exhaust pipes of the two turbine main units when welding them together, preventing the exhaust pipes of the two turbine main units from shaking and avoiding safety hazards caused by shaking.

[0025] In this specific embodiment, anti-slip pads 16 are fixedly installed on the surfaces of the eight second bolts 13. The anti-slip pads 16 are rubber pads, which can increase the friction between the second bolts 13 and the exhaust pipe.

[0026] In this specific embodiment, anti-detachment blocks 7 are fixedly installed on the inner walls of the eight slots 6. The anti-detachment blocks 7 can assist the first bolt 4 in fixing the connecting frame 2.

[0027] In this specific embodiment, auxiliary plates 8 are fixedly installed on the surfaces of the four first bolts 4. The surfaces of the auxiliary plates 8 abut against the anti-detachment block 7. The auxiliary plates 8 can prevent the first bolts 4 from sliding out of the inner wall of the slot 6.

[0028] In this specific embodiment, each of the four square plates 12 has a contact ball 15 fixedly installed at the end away from the arc plate 11. The size of the contact ball 15 is larger than the size of the locking hole 14. The contact ball 15 can prevent the square plate 12 from sliding out of the inner wall of the locking hole 14, thus achieving the effect of restricting the square plate 12 from sliding out of the inner wall of the locking hole 14.

[0029] In this specific embodiment, two positioning frames 9 are fixedly installed on the surface of each of the four connecting frames 2. A balance block 10 is slidably connected to the surface of the positioning frame 9. The surface of the balance block 10 is fixedly connected to the connecting frame 2.

[0031] Working principle: When two exhaust pipes need to be welded together, firstly, the connecting frame 2 is aligned with the positioning frame 9 and the balance block 10, and the two pairs of connecting frames 2 are placed around the two pipes respectively. Then, the first bolt 4 is inserted into the inner wall of the slot 6 on the connecting frame 2. Then, the fixing cylinder 5 is rotated, and the fixing cylinder 5 moves towards the connecting frame 2 with the help of the thread. After the fixing cylinder 5 moves a certain distance, the surface of the fixing cylinder 5 presses against the connecting frame 2, and the connecting frame 2 is fixed together. Then, the second bolt 13 is rotated, and the second bolt 13 moves towards the pipe with the help of the thread. After the second bolt 13 moves a certain distance, the anti-slip pad 16 on the second bolt 13 presses against the exhaust pipe, and the two exhaust pipes are fixed together. At this time, the pipes can be welded. During this process, the exhaust pipes will not shake.
