Description

Technical Field

[0001] This utility model relates to the field of steam turbine maintenance technology, specifically to a steam turbine maintenance parts storage device. Background Technology

[0002] A steam turbine, also known as a steam engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto blades, causing a rotor equipped with rows of blades to rotate and perform work. Steam turbines are the main equipment in modern thermal power plants. Regular maintenance is required to ensure the steam turbine operates normally and stably.

[0003] Chinese patent application number 202221555326.7 discloses a storage device for steam turbine repair parts, including a cabinet.

A guide rail is installed on the front side of the base cabinet, and a sliding door is slidably installed on the surface of the guide rail. Supports are installed on the inner walls of both sides of the top cabinet, and mounting plates are slidably connected to the supports. A sleeve is fixedly installed on the surface of the mounting plate. The base cabinet is divided into a first chamber and a second chamber by a vertical partition. The first chamber contains drawers. In this storage device for steam turbine repair parts, the mounting plate is pushed along a sliding groove to retrieve parts from the sleeve on the surface of the mounting plate. Furthermore, the design of the drawers and chambers within the base cabinet enhances the categorized management of tools.

[0004] However, the storage device for steam turbine maintenance parts still has some shortcomings in actual use. For example, the maintenance parts are stored in categories, so when taking out different maintenance parts, it is necessary to manually pull out the corresponding drawers one by one. After use, it is also necessary to manually push each drawer back. The above operations are highly repetitive, waste maintenance time, and are quite inconvenient. At the same time, when moving the storage equipment, the maintenance parts are not fixed and limited, so they will collide with each other during the movement, resulting in damage to some maintenance parts.

[0023] 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.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: including a frame component 1, an opening and closing component 2 is provided inside the frame component 1, and a limiting component 3 is fixedly installed on the back of the frame component 1;

[0025] The frame assembly 1 includes a box body 101. A box groove 102 is provided on one side of the box body 101. A step plate 103 is fixedly installed in the middle of the bottom surface of the box groove 102. A worm gear 105 is rotatably installed in the middle of the box groove 102. One end of the worm gear 105 passes through the front of the box body 101 and is fixedly installed with a handle 106.

[0026] The opening and closing assembly 2 includes a main rotating shaft 201. A prismatic plate 202 is fixedly sleeved on the top of the main rotating shaft 201. A secondary rotating shaft 203 is rotatably installed on both ends of the bottom surface of the prismatic plate 202. A transmission push-pull rod 204 is rotatably sleeved on the bottom of the shaft of each of the two secondary rotating shafts 203. A push-pull plate 205 is rotatably connected to the other end of each of the two transmission push-pull rods 204. A worm gear 206 is fixedly sleeved on the bottom of the shaft of the main rotating shaft 201. Several storage boxes 207 are fixedly installed on the outer side of each of the two push-pull plates 205.

[0027] The main shaft 201 is rotatably mounted at the center of the top surface of the step plate 103, and the worm wheel 206 is located on one side of the worm 105 and is meshed with the worm 105.

[0028] In this embodiment, the limiting component 3 includes a linear motor 301. An L-shaped support plate 302 is fixedly installed on the front of the slider of the linear motor 301. An I-shaped lifting plate 303 is fixedly installed on one end of the horizontal part of the L-shaped support plate 302. The L-shaped support plate 302 is controlled to descend by the linear motor 301. The descent of the L-shaped support plate 302 can drive the I-shaped lifting plate 303 to descend.

[0029] Meanwhile, several round rods 304 are fixedly installed on both sides of the bottom surface of the I-shaped lifting plate 303, and limit plates 305 are fixedly installed on the bottom surface of the several round rods 304. The linear motor 301 is fixedly installed in the middle of the back of the box 101, and the I-shaped lifting plate 303 is located above the top surface of the box 101.

[0030] The top surface of the box 102 has several panel slots 104 on both sides. Several limiting pressure plates 305 correspond one-to-one with several panel slots 104. Several round rods 304 are slidably inserted into the top surface of the box 101, and the bottom ends of the round rods 304 extend into the box 102. The limiting pressure plates 305 can press down on each maintenance part to prevent the maintenance parts in the storage box 207 from moving and colliding during transportation and causing damage.

[0031] The storage boxes 207 are divided into two groups, and the two groups of storage boxes 207 are slidably installed on both sides of the box groove 102. Different types of maintenance parts can be stored in the storage boxes 207.

[0032] In use, when it is necessary to retrieve maintenance parts, manually turn the handle 106. The handle 106 drives the worm gear 105 to rotate, which in turn drives the worm wheel 206 to rotate. The worm wheel 206 drives the main shaft 201 to rotate, which in turn drives the prismatic plate 202 to rotate. This causes the transmission push-pull rods 204 connected to both ends of the prismatic plate 202 to rotate and tend to be horizontal. The two transmission push-pull rods 204 can simultaneously push the two push-pull plates 205 to move to both sides. The movement of the two push-pull plates 205 can synchronously push out several storage boxes 207 set on both sides from the box slot 102, which can facilitate the staff to retrieve maintenance parts. After use, the handle 106 can be turned in the opposite direction to reset the two transmission push-pull rods 204, which can synchronously pull several storage boxes 207 back into the box slot 102, eliminating the need for manual repeated operation to push the storage boxes 207 back into the box body 101.

[0033] Simultaneously, the limiting pressure plate 305 descends and enters the top of the storage box 207. Each limiting pressure plate 305 presses down on the various repair parts, preventing damage from collisions during transportation. To ensure that the limiting pressure plates 305 at the same height can precisely limit the repair parts in multiple storage boxes 207, filling material can be added to each storage box 207 to ensure consistent height of the items. The filling material can be foam plastic, air-filled bags, cardboard, or laminated cardboard, etc. The linear motor 301 controls the L-shaped support plate 302 to descend, which in turn drives the I-shaped lifting plate 303 and the limiting pressure plates 305 to descend. The limiting pressure plates 305 press down on the various repair parts, preventing damage from movement and collisions during transportation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
