Description

Locking assembly system and auxiliary assembly

Technical Field

The utility model relates to a locking assembly system especially relates to an auxiliary assembly subassembly.

Background

The circumferential fixed locking of the booster stage rotor blade is usually realized by arranging a blade locking block assembly, so that the rotor blade is prevented from being separated in the working process. The blade lock block assembly can be seen in fig. 1 and consists of a lock block and a lock screw, which will be described in more detail later.

Under normal conditions, after rotor blade installation is accomplished, blade latch segment subassembly only exposes the locking screw that the diameter is about 5mm and is used for screwing up the latch segment, and the latch segment for example block part is whole to be sheltered from by the blade flange, and when latch segment block width was greater than the drum barrel tongue-and-groove, can use specialized tool to realize the locking assembly of latch segment, specific process is as follows: the latch segment is laid in the blade tongue-and-groove because self width is close with the tongue-and-groove width, and the location can be realized to latch segment self, avoids in the tongue-and-groove relative rotation.

The inventor analyzes that the blade locking block assembly can be simply divided into two processes in the assembling process: after the rotor blade is assembled, the locking screw interface is rotated by a special tool, and the locking block is in pressure connection with the mortise wall surface of the drum blade to realize locking; on one hand, the locking screw and the locking block generate relative motion to enable the locking block to ascend until the locking block abuts against the limiting groove on the upper end face of the mortise of the drum barrel to realize pressure connection, and on the other hand, the head or the lower bottom face of the screw abuts against the limiting point of the screw groove in the drum barrel or the bottom of the mortise to realize final locking.

In consideration of weight reduction, the overall size of the blade locking block assembly tends to be gradually reduced on the premise of meeting the positioning and locking functions, after the height of the locking block main body is smaller, the locking block assembly, particularly the width of the locking block, is reduced, the locking block is placed in a blade mortise, the locking block cannot be stopped when being in contact with the wall surface of a drum blade mortise due to the fact that the width of the locking block is reduced compared with the width of the mortise, the locking block rotates along with the blade locking block in the process of screwing a locking screw, the blade locking block assembly cannot be reliably locked and assembled by using a general tool, in other words, the blade locking block assembly cannot be clamped in a drum limiting groove to be circumferentially positioned in the initial assembly stage, and therefore difficulty is brought to the assembly of the blade locking block assembly.

Detailed Description

The present invention will be further described with reference to the following detailed description and the accompanying drawings, wherein the following description sets forth more details for the purpose of providing a thorough understanding of the present invention, but it is obvious that the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations and deductions based on the practical application without departing from the spirit of the present invention, and therefore, the scope of the present invention should not be limited by the contents of the detailed description.

For example, a first feature described later in the specification may be formed over or on a second feature, and may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

FIGS. 1 and 2 illustrate example configurations of a locking assembly 10, the following description taking locking assembly 10 as an example for achieving circumferentially fixed locking of a pressure stage rotor blade, however, it should be understood that locking assembly 10 may be used in other applications where locking is achieved in cooperation with a mortise. In the case of a circumferentially fixed locking of a pressure stage rotor blade, the locking assembly 10 is also often referred to as a blade locking block assembly or a pressure stage locking block assembly, and the pressure stage rotor blade is circumferentially fixed locked by the provision of the locking assembly 10 to avoid the rotor blade coming out during operation. It is also to be understood that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. Further, the conversion methods in the different embodiments may be appropriately combined.

Referring to fig. 1 and 2, a locking assembly 10 includes a locking block 1 and a locking screw 2. The locking block 1 has a locking screw hole 11. The locking screw 2 has a locking screw section 21, the locking screw 2 passes through the locking screw hole 11 of the locking block 1, and the bottom section 211 of the locking screw section 21 of the locking screw 2 is screwed with the locking screw hole 11 of the locking block 1. The "screw hole" means a hole having an inner peripheral side provided with at least a partial female screw thread, and the "screw" means a rod having an outer peripheral side provided with at least a partial male screw thread. The locking block 1 is placed in the mortise S0, and the top end 22 of the locking screw 2 is exposed out of the notch P0 of the mortise S0 and provided with the force application interface 220. The force application interface 220 is, for example, a shaped aperture, such as a hexagonal aperture, as shown in FIG. 1. For example, in chinese patent CN109209994A, a rotor blade locking device is disclosed, and the working principle of the locking assembly 10 is consistent with that of the rotor blade locking device disclosed therein.

In the embodiment shown in fig. 1, the locking screw hole 11 of the locking block 1 comprises a top hole section 112 and a bottom hole section 111. The bottom hole section 112 of the locking block 1 is screwed with the bottom section 211 of the locking screw section 21 of the locking screw 2, and an annular gap G1 is formed between the top hole section 112 of the locking block 1 and the top section 212 of the locking screw section 21 of the locking screw 2.

In the embodiment shown in fig. 1 and 2, the locking block 1 comprises a block 12 and a threaded sheath 13. The block 12 has a block screw hole 121. The threaded sheath 13 has a sheath screw hole 131 and a sheath outer peripheral surface 132 provided with external threads 13 a. The screw protector 13 is engaged with the block 12 by fitting the protector outer peripheral surface 132 (specifically, the external thread 13a provided by the protector outer peripheral surface 132) into the block screw hole 121, and is engaged with the locking screw 2 by fitting the protector screw hole 131 into the bottom section 211 of the locking screw section 21 of the locking screw 2. The top portion 1211 of the unthreaded threaded sheath 13 of the block screw hole 121 constitutes the top bore section 112 of the aforementioned locking screw hole 11, and the sheath screw hole 131 constitutes the bottom bore section 111 of the locking screw hole 11.

In other words, the locking assembly 10 may include the block 12, the threaded sheath 13 and the locking screw 2, after the block 12 may be connected with the threaded sheath 13 to form the locking block 1, the block is connected with the locking screw 2 through a thread pair, and a self-locking torque may be present in the locking screw 2 during the rotation process, so that the locking assembly 10 may be prevented from being loosened in an environment where vibration is present, and reliable locking of the blade locking mechanism may be achieved.

Fig. 3 to 6 show an example configuration of the subsidiary fitting assembly 20. In the illustrated embodiment, the sub-assembly 20 and the locking assembly 10 together form a locking assembly system for assisting in assembling/installing the locking assembly 10, however, it should be understood that this does not limit the application environment of the sub-assembly 20, and the sub-assembly 20 may be applied to other suitable application environments. Additionally, it should be understood that in the foregoing and subsequent descriptions, spatial relational terms, such as "top," "bottom," "upper," "lower," and the like, may be used for convenience in describing the relationship of one element or feature to another element or feature illustrated in the figures. It will be understood that these terms of spatial relationship are intended to encompass other orientations of the element or component in use or operation in addition to the orientation depicted in the figures. For example, if the components in the figures are turned over, elements described as "bottom" on other elements or features would then be oriented "top" on the other elements or features, and the spatially relative descriptors used herein should be interpreted accordingly.

Referring to fig. 3 to 5, the auxiliary fitting assembly 20 includes a connecting cylinder 3 and a tightening rod 4.

The connector barrel 3 has a barrel bore 300 and the connector barrel 3 includes a bottom barrel section 31 provided with a threaded bore section 301. The threaded bore section 301 of the bottom barrel section 31 is adapted to threadedly engage the top section 212 of the locking screw section 21 of the locking screw 2 of the locking assembly 10. For the locking assembly 10 shown in fig. 1 and 2, the bottom barrel section 31 of the connector barrel 3 is adapted to be placed into the annular gap G1 of the locking assembly 10 to threadedly engage the top section 212 of the locking screw section 21. In other words, the outer peripheral wall diameter of the bottom barrel section 31 of the connecting barrel 3 is smaller than the small diameter of the internal thread of the top bore section 112 of the locking block 1 (specifically, the block screw hole 121 of the block 12). In this way, the connecting cylinder 3 and the locking screw 2 can obtain a sufficient threaded connection section, and the connecting cylinder 3 can freely move up and down in the locking block 1 (specifically, the block 12).

The tightening rod 4 passes through the bore 300 of the connector barrel 3, and the bottom end 41 of the tightening rod 4 passes out of the bore 300 of the connector barrel 3 and is adapted to engage the force application interface to apply torque to the component providing the force application interface. In the illustrated embodiment, the force application interface, i.e., the force application interface 220 of the top end 22 of the locking screw 2 of the locking assembly 10, is provided with a component of the force application interface, i.e., the locking screw 2, such that the bottom end 41 of the tightening rod 4 protrudes through the bore 300 of the connector barrel 3 and is adapted to engage the force application interface 220 of the top end 22 of the locking screw 2 to apply a torque to the locking screw 2. The force application interface 220 may be a torque wrench interface, for example, if the force application interface 220 of the locking screw 2 shown in fig. 1 is a shaped hole, such as a hexagonal hole, then the bottom end 41 of the tightening rod 4 is also correspondingly configured as a shaped column, such as a hexagonal prism, as shown in fig. 6. The tip end 42 of the tightening rod 4 may be provided as a force application end for applying force, for example, also in a hexagonal prism shape, and the lateral dimension (the left-right dimension in fig. 6) is large for applying force for screwing with a wrench.

In an initial state, as shown in fig. 2, the distance between the top end 22 or the upper end face of the locking screw 2 and the upper end face 122 of the locking block 1 or the block 12 is relatively large, and when the distance is different, for example, about 5mm, the locking block 1 can be clamped into the limiting groove on the upper side of the mortise (for example, the position of fig. 1), so that, in a stage that the locking assembly 10 is not clamped into the limiting groove, the connecting cylinder 3 is connected with the locking screw 2, the tightening rod 4 is arranged to lift the locking screw 2 along the threaded connection section between the connecting cylinder 3 and the locking screw 2, at this time, the locking block 1 is not limited and moves upward together with the locking screw 2, that is, the locking assembly 10 is lifted integrally until the locking block 1 or the block 12 is clamped into the limiting groove, the locking screw 2 is tightened by the tightening rod 4 to sink the locking screw 2 relative to the locking block 1, and after the lower bottom face of the locking screw 2 is contacted with the, the installation of the locking assembly 10 is completed.

In practice, the connecting cylinder 3 may be pressed against the table B1 (shown in fig. 1) where the mortise S0 is located, for example, by hand holding or using other tools, and the screw hole section 301 of the bottom cylinder section 31 of the connecting cylinder 3 is aligned with the top section 212 of the locking screw section 21 of the locking screw 2; then, the bottom end 41 of the tightening rod 4 passed through the cylinder hole 300 is engaged with the force application port 220 of the top end 22 of the locking screw 2, and the locking screw 2 is moved upward relative to the connector cylinder 3 by screwing the tightening rod 4 in the first screwing direction to be screwed with the bottom cylinder section 31 of the connector cylinder 3 to form a screw coupling section, at which time, since the locking block 1 is still at the lower position of the mortise S0, the stopper groove portion capable of being caught in the circumferential direction thereof is not reached, and therefore, the locking screw 2 moves upward together with the locking assembly 10 (including the locking block 1) as a whole. After a threaded connection section with a certain length is formed between the locking screw 2 and the connecting cylinder 3, the locking block 1 can reach the part of the limiting groove which is clamped in the circumferential direction, and it is to be understood that the locking block 1 can prevent rotation after reaching the part of the limiting groove which is clamped in the circumferential direction at the top. At this time, the connector barrel 3 may be held by hand or by other means to be kept stationary, and the locking screw 2 is moved downward relative to the connector barrel 3 by screwing the tightening rod 4 in a second screwing direction, which is opposite to the first screwing direction before, for example, one in a clockwise direction and the other in a counterclockwise direction. At this time, since the locking block 1 has reached the limit groove portion which can clamp it in the circumferential direction, the locking block 1 cannot rotate together with the locking screw 2 due to the circumferential rotation stopping action of the limit groove portion, and thus, when the locking screw 2 is rotated by the screwing action of the tightening rod 4, the threaded connection section with the connection cylinder 3 is gradually reduced in downward movement while also moving downward relative to the locking block 1 until the bottom end of the locking screw 2 abuts against the bottom surface of the mortise, as shown in fig. 1.

The complementary fitting assembly 20 also comprises a containment drum 5. The accommodation tube 5 includes two inner flanges 50a, 50b, fig. 4, an upper flange 50a and a lower flange 50b, each projecting toward the inner peripheral side with an axial gap T1 therebetween.

The connector barrel 3 also has a top barrel section 32. The top cylinder section 32 has an outer flange 321 projecting toward the outer circumferential side. The connector barrel 3 is axially (vertically in fig. 5) restricted with respect to the housing barrel 5 by the outer flange 321 being locked to an axial gap T1 between the two inner flanges 50a and 50b of the housing barrel 5. In other words, the connection barrel 3 and the accommodation barrel 5 are limited by the seam allowance. The connecting cylinder 3 can be changed according to the size of the locking assembly 10, and can be replaced quickly.

The connecting cylinder 3 can be held or moved by controlling the accommodating cylinder 5. The tightening rod 4 passes through the connecting cylinder 3 accommodated in the accommodating cylinder 5 to match and engage with the force application interface 220 of the locking screw 2, thereby achieving the tightening function of the locking screw 2.

The accommodation tube 5 may have a bottom wall 53 provided with a bottom hole 5a and a peripheral wall 54 provided with a pin hole 5 b. In other words, the accommodating cylinder 5 has a cylindrical structure with a hole closed on one side. The accommodation tube 5 is also provided with a handle 6 extending radially outward from the peripheral wall 54 for moving or holding the accommodation tube 5. The accommodation cylinder 5 is further provided with a pin 7 such as a cylindrical pin inserted into the pin hole 5 b. The bottom barrel section 31 of the connecting barrel 3 passes through the bottom hole 5a of the accommodating barrel 5, and the part of the pin 7 extending into the barrel hole 500 of the accommodating barrel 5 and the bottom wall 53 of the accommodating barrel 5 respectively form two inner flanges 50a and 50b of the accommodating barrel 5. In the illustrated embodiment, the side of the receiving cylinder 5 may be provided with a threaded hole so that the handle 6 may be attached.

The receiving barrel 5, and thus the connecting barrel 3, may be conveniently moved or held using the handle 6. The pin 7 can restrict the axial displacement of the connecting cylinder 3, realize that the connecting cylinder 3 is axially limited in the threaded connection process of the locking assembly 10, and also can prevent the connecting cylinder 3 from falling off and losing from the accommodating cylinder 5 when in use and storage.

The handle 6 is connected with the accommodating cylinder 5 and is used for realizing the functions of connection and lifting with the locking assembly 10 together with the connecting cylinder 3, and further realizing the pressure connection of the locking block 1 (specifically, the block 12) and the upper end surface or the limiting groove of the mortise S0. The connector cylinder 3 may be accommodated in the cylindrical space of the accommodation cylinder 5, and the connector cylinder 3 may be rotated relative to the accommodation cylinder 5, as shown in fig. 3. The complementary fitting assembly 20 may also include a twist barrel 8. Referring to fig. 3, the tightening rod 4 passes through the cylinder hole 800 of the screwing cylinder 8 and the cylinder hole 300 of the connecting cylinder 3 in this order. The screwing cylinder 8 is provided at the bottom end with a shaped post or hole 81 (in the figure, shaped post, for example quadrangular prism), and the connecting cylinder 3 is provided at the top end with a corresponding shaped hole or post 38 (in the figure, shaped hole, for example quadrangular hole). The screwing cylinder 8 is butted with the special-shaped hole or the column 38 through the special-shaped column or the hole 81 to apply torque to the connecting cylinder 3, and the applied torque can be screwing torque or anti-rotation and stopping torque. The twist barrel 8 may also have a top force application end 82 to facilitate application of force to the twist barrel 8 to apply force to the connector barrel 3 by interfacing with the profiled bore or post 38 through the profiled post or bore 81, e.g., the top force application end 82 is square.

With reference to fig. 7 to 10, the locking assembly system can operate as follows: preliminarily butt-jointing the internal thread (the screw hole section 301 of the bottom barrel section 31) of the connecting barrel 3 with the locking screw 2 (the top section 212 of the locking screw section 21), keeping the bottom end of the screwing barrel 8 to press the connecting barrel 3, and rotating the screwing barrel 8 by an operator to enable the connecting barrel 3 to be in threaded connection with the locking screw 2, wherein a short threaded connection section is arranged between the connecting barrel 3 and the locking screw 2 as shown in fig. 7; after the connecting cylinder 3 is screwed with the locking screw 2, the auxiliary assembling component 20 and the locking component 10 are integrally lifted, and then, when the tightening rod 4 is screwed to the middle position by an operator using a wrench or manually, as shown in fig. 8; then, the locking screw 2 is screwed to the bottom continuously, as shown in fig. 9; then, by rotating the screwing cylinder 8, the connecting cylinder 3 is disengaged from the locking screw 2, as shown in fig. 10. The tightening rod 4 can now be removed, by which the mounting operation of the locking assembly 10 is completed.

It should be understood that, as shown in fig. 11, the threaded connection section L1 between the connecting cylinder 3 and the locking screw 2 is much smaller than the distance L2 from the bottom of the mortise to the locking screw 2 after the auxiliary assembly unit 20 and the locking unit 10 are lifted integrally, and the threaded connection section L1 between the connecting cylinder 3 and the locking screw 2 is shorter because in practice, the upper and lower threads are connected between the connecting cylinder 3 and the locking screw 2, and a large torque is required for the subsequent tightening. At this time, the locking screw 2 cannot be completely screwed down by loosening the threaded connection section L1. The manner of operation of fig. 7-10 described above may thus be taken.

The locking assembly system solves the problem that the locking block can not be installed because the locking block rotates along with the rotation of the locking screw in the installation process of the locking assembly, wherein the locking block can be stopped by the pressure connection of the special-shaped surface at the top of the locking block and the matching surface at the top of the mortise of the blade, in other words, the locking block can be stopped by the positioning surface of the mortise, the locking block is connected with the pressure of the positioning surface at the top end of the mortise by lifting the locking block, so that the locking block can be stopped, particularly, the auxiliary assembly component can realize the function of dividing into two parts, namely, the lifting function of the locking block and the screwing function of the locking block screw, moreover, the structural design of separating the lifting and stopping structure from a special screwing tool is adopted, the locking block can be stopped by lifting the locking block, and the problem that the locking block is difficult to assemble because the size of the locking block is reduced, the assembly efficiency is improved. This locking assembly system especially assists the assembly subassembly and has adopted separable structural design, can satisfy different grades of rotor blade locking piece installation and wildcard, can effectively reduce frock clamp manufacturing cost.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention, all without departing from the content of the technical solution of the present invention, fall within the scope of protection defined by the claims of the present invention.
