Description

Technical Field

[0001] This utility model relates to the field of safety and material manufacturing technology, specifically to an anti-detachment device for connecting the adjustment cylinder of a TRT turbine to the pistol plate. Background Technology

[0002] TRT turbines are energy-saving devices that use the pressure and heat energy of blast furnace top gas to drive a turbine expander to generate electricity. They are widely used in steel enterprises. TRT turbines drive the rotation of the stationary blade bearing cylinder by the horizontal reciprocating operation of the regulating cylinder. The blast furnace pressure and generator power generation are controlled by adjusting the blade opening.

[0003] Currently, some existing pistol plates and regulating cylinders use planar contact, connected by three bolts and two pins. During TRT operation, the pistol plates frequently reciprocate horizontally, causing fatigue of the connecting parts over time. Under shear force, fatigue fracture occurs. Furthermore, the TRT regulating cylinder is controlled by two hydraulic cylinders. When the two hydraulic cylinders operate asynchronously, the resistance load on the regulating cylinder becomes unbalanced, which can easily lead to the breakage of the connecting bolts and pins between the regulating cylinder and the pistol plate. After the connecting bolts and pins between the pistol plate and the regulating cylinder are broken, the opening of the stationary blade bearing cylinder becomes uncontrollable, making it impossible to regulate the blast furnace top pressure and power generation. In severe cases, this can cause the TRT to overspeed, posing a significant safety risk. When the stationary blade bearing cylinder cannot be adjusted, the unit must be shut down, affecting the company's overall power generation, causing energy waste and increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an anti-detachment device for the connection between the TRT turbine regulating cylinder and the pistol plate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing the TRT turbine's adjusting cylinder from detaching from the pistol plate, comprising a servo cylinder and a pistol plate body fixedly connected to its output end, and further comprising: A fixing pin is installed on the inner surface of the pistol plate body. An adjusting cylinder body is installed on the upper end of the outer surface of the fixing pin. A bolt is threaded on the inner surface of the pistol plate body. Adjusting cylinder DU sliders are installed around the adjusting cylinder body. A protrusion is fixedly connected to the top of the pistol plate body. A groove is provided on the inner surface of the adjusting cylinder body. Reinforcing mechanisms to enhance the anti-dislodgement effect are installed on the inner surfaces around the adjusting cylinder body.

[0006] Preferably, the reinforcement mechanism includes a threaded rod rotatably connected to one side of the inner surface of the regulating cylinder body, a threaded plate threadedly connected to the outer surface of the threaded rod, an insert rod fixedly connected to one side of the threaded plate, and a knob fixedly connected to the other side of the threaded rod.

[0007] Preferably, a guide rod is slidably connected to the inner surface of the threaded plate, and the two sides of the guide rod are fixedly connected to the two sides of the inner surface of the adjusting cylinder body.

[0008] Preferably, a socket is provided on one side of the protrusion.

[0009] Preferably, the number of protrusions is six, and the number of grooves is six.

[0010] Preferably, a sliding sleeve is fixedly connected to one side of the pistol plate body, and a sliding rod is fixedly connected to one side of the servo cylinder, with the inner surface of the sliding sleeve slidably connected to the outer surface of the sliding rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the setting of protrusions and grooves, transforms the planar contact friction of the contact surface into a slightly interference fit contact with concave and convex surfaces. This increases the shear force of the regulating cylinder and the pistol plate, transferring the shear force of the connecting parts to the pistol plate and the regulating cylinder, reducing the shear force of the connecting parts, preventing breakage, ensuring the normal connection and movement of the regulating cylinder and the pistol plate, reducing the number of TRT turbine unit shutdowns due to malfunctions, and allowing for normal adjustment of the blade opening of the stationary blade bearing cylinder. This facilitates the adjustment of the blast furnace top pressure, ensures TRT power generation, and effectively prevents overspeed accidents. At the same time, the reinforcement mechanism can fix the pistol plate body and the regulating cylinder body, effectively improving the stability of the connection and thus improving the anti-detachment effect.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4 As shown, a device for preventing the detachment of the adjustment cylinder and the pistol plate of a TRT turbine includes a servo cylinder 1. The output end of the servo cylinder 1 is fixedly connected to the pistol plate body 2. A fixing pin 3 is installed on the inner surface of the pistol plate body 2. An adjustment cylinder body 5 is installed on the upper end of the outer surface of the fixing pin 3. The pistol plate body 2 and the adjustment cylinder body 5 can be connected and fixed by the fixing pin 3, thus ensuring its stability during use.

[0016] The inner surface of the pistol plate body 2 is threaded with a bolt 4. The upper end of the outer surface of the bolt 4 is threaded to one side of the inner surface of the adjusting cylinder body 5. The bolt 4 can strengthen the connection between the pistol plate body 2 and the adjusting cylinder body 5, thereby improving the stability when fixed.

[0017] The regulating cylinder body 5 is equipped with regulating cylinder DU sliders 6 around its perimeter. The top of the pistol plate body 2 is fixedly connected with a protrusion 7. The inner surface of the regulating cylinder body 5 is provided with a groove, and the size of the groove is the same as the size of the protrusion 7. By setting the protrusion 7 and the groove, the planar contact friction of the contact surface can be transformed into a slightly interference fit contact with the concave and convex surfaces, increasing the shear force of the regulating cylinder and the pistol plate, transferring the shear force of the connecting parts to the pistol plate and the regulating cylinder, reducing the shear force of the connecting parts, preventing the connecting parts from breaking, ensuring the normal connection and movement of the regulating cylinder and the pistol plate, reducing the number of TRT turbine unit failures and shutdowns, and ensuring the normal adjustment of the blade opening of the stationary blade bearing cylinder, which facilitates the adjustment of the blast furnace top pressure, ensures the power generation of the TRT, and effectively prevents overspeed accidents.

[0018] The inner surfaces of the regulating cylinder body 5 are all equipped with reinforcement mechanisms 9 to enhance the anti-detachment effect. Through the setting of reinforcement mechanisms 9, the pistol plate body 2 and the regulating cylinder body 5 can be fixed, achieving a multi-connection and fixing effect, effectively improving the stability of the connection, thereby improving the anti-detachment effect.

[0019] The reinforcing mechanism 9 includes a threaded rod 901 rotatably connected to one side of the inner surface of the regulating cylinder body 5. A threaded plate 902 is threadedly connected to the outer surface of the threaded rod 901. A plug rod 903 is fixedly connected to one side of the threaded plate 902, and a knob 904 is fixedly connected to the other side of the threaded rod 901. One side of the threaded rod 901 passes through one side of the regulating cylinder body 5 and is rotatably connected to its inner wall. By turning the knob 904 through the reinforcing mechanism 9, the threaded rod 901 is rotated. The threaded rod 901 moves the threaded plate 902 and the plug rod 903, allowing the plug rod 903 to be inserted into the insertion hole of the protrusion 7 for reinforcement and fixation, effectively improving the stability of the connection.

[0020] The inner surface of the threaded plate 902 is slidably connected to a guide rod 8. The two sides of the guide rod 8 are fixedly connected to the two sides of the inner surface of the adjusting cylinder body 5. Through the guide rod 8, the threaded plate 902 can move left and right, which facilitates the insertion of the insertion rod 903 for reinforcement and fixation, and makes it more stable when moving.

[0021] A insertion hole is provided on one side of the protrusion 7, and the diameter of the insertion hole is the same as the diameter of the insertion rod 903. The insertion hole allows the insertion rod 903 to be easily inserted for reinforcement and fixation. The same diameter ensures that the fixation will not be affected when shaking occurs.

[0022] There are six protrusions 7 and six grooves. By setting the number of protrusions 7 and grooves to six, they can be made to correspond to each other, which facilitates insertion and improves the contact effect.

[0023] A sliding sleeve is fixedly connected to one side of the pistol plate body 2, and a sliding rod is fixedly connected to one side of the servo cylinder 1. The inner surface of the sliding sleeve is slidably connected to the outer surface of the sliding rod. Through the sliding sleeve and the sliding rod, the pistol plate body 2 can be supported and moved, thereby improving its stability during movement and preventing the output end of the servo cylinder 1 from tilting or breaking during reciprocating movement, thus preventing damage from affecting the operation.

[0024] It is worth noting that the technical features such as the servo cylinder 1 and the regulating cylinder body 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] Working principle: The pistol plate body 2 and the regulating cylinder body 5 can be connected and fixed by the fixing pin 3. The regulating cylinder body 5 can be threaded and fixed. By opening a groove on the contact surface of the regulating cylinder body 5 and making a protrusion 7 on the contact surface of the pistol plate body 2, the planar contact friction of the contact surface is transformed into a slightly interference fit contact with concave and convex surfaces. This increases the shear force of the regulating cylinder and the pistol plate, transfers the shear force of the connecting parts to the pistol plate and the regulating cylinder, reduces the shear force of the connecting parts, prevents the connecting parts from breaking, ensures the safe and stable operation of the unit, regulates the blast furnace top pressure, regulates the power generation, and prevents overspeed accidents. This patent solves the long-standing technical difficulties in the field, and the field application effect is significant.

[0026] By turning the knob 904, the threaded rod 901 is rotated, which in turn moves the threaded plate 902 and the insertion rod 903. The insertion rod 903 can be inserted into the insertion hole of the protrusion 7 for reinforcement and fixation, which effectively improves the stability of the connection and thus enhances the anti-detachment effect.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
