Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Example (b):

as shown in fig. 1, the valve structure dismounting tool provided in this embodiment includes a first pull rod 1 and a driving assembly 2. The first pull rod 1 is used for being connected with a valve body 30 in the valve structure 3, the driving assembly 2 can be arranged on a foreign object 4 provided with the valve structure 3, and the output side of the driving assembly 2 can be connected with the first pull rod 1. The output side of the drive assembly 2 can be moved relative to the foreign object 4 to bring the first pull rod 1 along its axial direction in a direction away from the foreign object 4.

The valve structure dismounting tool provided by the embodiment is used for dismounting the valve structure 3 mounted on the foreign object 4, wherein the foreign object 4 is a device such as a generator, and the valve structure 3 can comprise a valve body 30 such as a throttle valve. The outer peripheral wall of the valve body 30 such as the throttle valve may be sleeved with a bearing 31 at a position near both ends, and the bearing 31 is interference-fitted in the cylindrical through hole 40 of the foreign object 4.

Use the utility model provides a valve structure dismantles apparatus and dismantles when installing valve structure 3 on foreign object 4, will set up drive assembly 2 in this valve structure dismantles apparatus on foreign object 4 earlier to be connected first pull rod 1 and drive assembly 2's output side, and be connected first pull rod 1 and valve body 30 in the valve structure 3, start drive assembly 2 then, make drive assembly 2's output side remove for foreign object 4. After the output side of the driving assembly 2 moves relative to the foreign object 4, the first pull rod 1 can be moved in the axial direction thereof away from the foreign object 4 by the driving assembly 2, so as to take out the valve body 30 from the foreign object 4.

Compared with the prior art, the valve structure dismantlement apparatus that this embodiment provided utilizes drive assembly 2 and first pull rod 1 to mutually support, can pull out valve body 30 in the valve body 30 structure from foreign object 4 along the axial of first pull rod 1, need not utilize means such as strike, sled to take out valve body 30 from foreign object 4, and then can promote the work efficiency of dismantlement process, and can reduce the damage that the dismantlement process led to the fact throttle valve and generator, thereby can prevent throttle valve and generator and scrap.

In which the bearing 31 near the top end of the valve body 30 is easily taken out together with the valve body 30 when the valve body 30 is taken out from the foreign object 4, but the bearing 31 near the bottom end of the valve body 30 is easily caught in the through hole 40 of the foreign object 4 due to interference fit. If the bearing 31 is jammed in the through hole 40 of the foreign object 4, the process of disassembling the valve structure 3 can be divided into two stages, and in the first stage, the driving assembly 2 and the first pull rod 1 cooperate to pull the valve body 30 out of the through hole 40 of the foreign object 4. In the second stage, the bearing 31 can be pried out of the through hole 40 of the foreign object 4 by prying, or the driving assembly 2 and the first pull rod 1 are continuously matched to pull out the bearing 31 from the through hole 40 of the foreign object 4.

It should be noted that, no matter how the bearing 31 is taken out from the through hole 40 of the foreign object 4, since the valve body 30 in the valve structure 3 is already pulled out according to the mutual cooperation of the driving assembly 2 and the first pull rod 1, when the valve structure 3 is disassembled by using the valve structure disassembling tool provided by this embodiment, the working efficiency of the disassembling process can still be improved, and the damage to the throttle valve and the generator caused by the disassembling process can be reduced, so that the throttle valve and the generator can be prevented from being scrapped.

It can be seen that, the valve structure dismantlement apparatus that this embodiment provided when having alleviated the throttle in the organism of the generator among the dismantlement generating set that exists among the prior art, need utilize means such as strike, sled to take out the throttle from the perforation of organism, not only dismantle inefficiency, and the in-process of dismantling is too violent hard easily, causes the technical problem of damage to throttle and generator.

As shown in fig. 1, the driving assembly 2 of the present embodiment includes a bracket 20 and a driving member 21, and the bracket 20 is configured to be disposed on the foreign object 4. The output side of the drive assembly 2 is located on a drive element 21, which drive element 21 can be connected to the support 20 and to the first tension rod 1.

The bracket 20 is used to support the driving member 21 such that the driving member 21 is easily moved relative to the foreign object 4.

In this embodiment, the bracket 20 may have a heavy weight, which can satisfy the requirement that the bracket 20 is not easy to deviate when the bracket 20 is placed on the foreign object 4. Further, the material of the bracket 20 may be iron alloy or stainless steel.

Alternatively, the bracket 20 may be fixed to the foreign object 4 by screwing, clipping, or the like.

In practical application, the driving member 21 may be an electric element such as an air cylinder or an electric push rod, and the output side of the driving member 21 may be connected to the first pull rod 1 by means of plugging, clamping or screwing. When the driving member 21 is activated, the driving member 21 is extended, and the first pull rod 1 can be driven to move along the axial direction thereof in a direction away from the foreign object 4.

In the present embodiment, as shown in fig. 1 and 2, the bracket 20 is in a groove shape, the open end of the bracket 20 can be disposed on the external object 4, and the groove bottom of the bracket 20 is disposed opposite to the side of the valve structure 3 exposed to the external object 4. The tank bottom of support 20 is provided with first perforation 200, is provided with the external screw thread that matches with the screw hole phase-match on the valve body 30 of valve structure 3 on the first pull rod 1, and wherein one end of first pull rod 1 can pass behind first perforation 200 threaded connection in the screw hole on valve body 30. The driving member 21 is a nut, the output side of the driving assembly 2 is an internal thread of the nut, and the nut can be connected to the first pull rod 1 in a threaded manner and attached to one side of the groove bottom of the support 20, which is far away from the valve body 30.

When the valve body 30 in the valve structure 3 needs to be disassembled, the open end of the bracket 20 may be placed on the external object 4, and the bottom of the groove of the bracket 20 is relatively disposed on the side of the valve structure 3 exposed to the external object 4, and at this time, a space is formed between the bottom of the groove of the bracket 20 and the valve body 30. Then, one end of the first pull rod 1 can be threaded into the threaded hole of the valve body 30 after passing through the first through hole 200, and then the driving member 21 can be threaded onto the first pull rod 1 after passing through the other end of the first pull rod 1, so that the driving member 21 moves toward the direction close to the bracket 20 until the driving member 21 is attached to the side, away from the valve body 30, of the bottom of the groove of the bracket 20.

In the process of screwing the driving member 21 on the first pull rod 1 and moving the driving member 21 toward the direction approaching the bracket 20, the rotation direction of the driving member 21 may be clockwise or counterclockwise. Taking the rotation direction of the driving member 21 as a clockwise direction as an example, the driving member 21 attached to one side of the bottom of the bracket 20 continues to rotate clockwise at this time, and the valve body 30 can be smoothly and easily pulled out of the through hole 40 of the foreign object 4 by using the acting force between the driving member 21 and the bracket 20 and the acting force between the driving member 21 and the first pull rod 1. The process of rotating driving piece 21 can utilize tools commonly used such as spanner to realize, and the process of pulling valve body 30 through rotatory driving piece 21 compares in current sled mode, and is not only laborsaving, can promote work efficiency, and is difficult for damaging valve body 30 and foreign object 4.

It should be noted that the space between the groove bottom of the bracket 20 and the valve body 30 is used for providing a moving space for the process of moving the valve body 30 in the direction away from the foreign object 4, so that the moving process of the valve body 30 is not hindered by the bracket 20. Because the connection between the valve body 30 and the through hole 40 of the foreign object 4 is realized by interference fit between the two bearings 31 sleeved on the outer peripheral wall of the valve body 30 and the through hole 40 of the foreign object 4, in the process of disassembling the valve body 30, after the bearing 31 close to the top end of the valve body 30 and the valve body 30 are pulled together, the valve body 30 can be separated from the bearing 31 close to the bottom end of the valve body 30, at this moment, the rotating driving member 21 is stopped, and the valve body 30 can be easily taken out from the through hole 40 of the foreign object 4 by directly pulling the first pull rod 1, so that the height of the interval between the groove bottom of the support 20 and the valve body 30 does not need to be greater than the height of.

It can be seen that in the valve structure disassembling tool provided in this embodiment, the first stage in the process of disassembling the valve structure 3 can be completed by using the first pull rod 1, the bracket 20 and the driving member 21 to cooperate with each other, and by rotating the driving member 21.

As shown in fig. 3, the valve structure dismounting tool provided in this embodiment further includes a second pull rod 5, the second pull rod 5 is provided with an external thread matching the internal thread of the nut, and as shown in fig. 2, the bottom of the groove of the bracket 20 is provided with a second through hole 201. As shown in fig. 3, when the output side of the driving assembly 2 moves relative to the foreign object 4 and drives the first pull rod 1 to move in the direction away from the foreign object 4 along the axial direction thereof, the valve body 30 in the valve structure 3 is separated from the foreign object 4, and the bearing 31 sleeved on the valve body 30 in the valve structure 3 remains on the foreign object 4, one end of the second pull rod 5 can pass through the second through hole 201 and then be connected with the bearing 31 remaining in the foreign object 4. The nut can be threaded on second pull rod 5 and the laminating is in the tank bottom of support 20 one side of keeping away from valve body 30, and the nut can be at the in-process of rotation, and the direction that drives second pull rod 5 and keep away from foreign object 4 along its axial orientation removes.

When the output side of the driving assembly 2 moves relative to the foreign object 4 and drives the first pull rod 1 to move in the direction away from the foreign object 4 along the axial direction, the valve body 30 in the valve structure 3 is separated from the foreign object 4, and the bearing 31 sleeved on the valve body 30 in the valve structure 3 is left on the foreign object 4, the process of disassembling the valve structure 3 can enter the second stage, and at this time, the bearing 31 clamped in the through hole 40 of the foreign object 4 in the valve structure 3 needs to be taken out.

When the bearing 31 clamped in the through hole 40 of the foreign object 4 is disassembled, the first pull rod 1 and the driving piece 21 can be separated, the first pull rod 1 is taken down from the bracket 20, then the bracket 20 is placed on the foreign object 4 again, and as the bearing 31 is positioned inside the through hole 40 of the foreign object 4 and a certain distance is reserved between the bearing 31 and the top end of the through hole 40, the open end and the groove bottom of the bracket 20 can be in contact or connected with the foreign object 4 at the moment, and only the position of the groove bottom of the bracket 20 is required to be opposite to that of the bearing 31.

After the position of the bracket 20 is fixed on the foreign object 4, one end of the second pull rod 5 is connected with the bearing 31 after passing through the second through hole 201, then the driving piece 21 is connected with the second pull rod 5 through the other end of the second pull rod 5 by screw threads, and the driving piece 21 is moved in the direction close to the bracket 20 until the driving piece 21 is moved to the side, far away from the bearing 31, of the bottom of the groove attached to the bracket 20. When the driving member 21 is screwed to the second pull rod 5, the rotation direction of the driving member 21 may be clockwise or counterclockwise, and similarly, taking the rotation direction of the driving member 21 as a clockwise direction as an example, the driving member 21 attached to the bottom side of the groove of the bracket 20 continues to rotate clockwise at this time, and the bearing 31 may be pulled out from the through hole 40 of the foreign object 4 by using the acting force between the driving member 21 and the bracket 20 and the acting force between the driving member 21 and the second pull rod 5. The process of rotating the driving member 21 can be performed by using a wrench, a power push rod, or the like.

As shown in fig. 3 and 4, the valve structure removing tool provided in this embodiment further includes a lock nut 6, and the lock nut 6 can be screwed on the external thread of the second pull rod 5 and abut against a side of the nut away from the foreign object 4. The inner wall of the second through hole 201 is provided with an internal thread matching with the external thread of the second pull rod 5.

When the valve structure remover provided by this embodiment further includes the lock nut 6, and the inner wall of the second through hole 201 is provided with the internal thread matching with the external thread of the second pull rod 5, when the second pull rod 5 is assembled on the bracket 20, one end of the second pull rod 5 needs to pass through the second through hole 201 and rotate the second pull rod 5 in the second through hole 201, so that one end of the second pull rod 5 can reach the bearing 31, and in this process, the second pull rod 5 is screwed in the second through hole 201. After the second pull rod 5 is moved to the right position, the driving member 21 is screwed on the second pull rod 5 along the clockwise direction, the driving member 21 is attached to one side of the bottom of the bracket 20, which is far away from the bearing 31, then the lock nut 6 is screwed on the second pull rod 5 along the clockwise direction, and the lock nut 6 is attached to one side of the driving member 21, which is far away from the bracket 20.

Then, the driving member 21 can be rotated in the counterclockwise direction, at this time, the driving member 21 and the lock nut 6 are interlocked, the driving member 21 still abuts on one side of the groove bottom of the bracket 20, the lock nut 6 still abuts on one side of the driving member 21, but the second pull rod 5 moves in the axial direction of the second pull rod 5 in the direction away from the foreign object 4 during the counterclockwise rotation of the driving member 21, so that the bearing 31 connected with the second pull rod 5 can be driven to exit from the through hole 40 of the foreign object 4 together with the second pull rod 5.

The lock nut 6 is used to create an interlocking action with the driver 21 and thereby define the position of the driver 21. In practical applications, the acting force between the bearing 31 clamped in the through hole 40 of the foreign object 4 and the inner wall of the through hole 40 is relatively large, and the bearing 31 is not easy to withdraw from the through hole 40, while the valve structure disassembling tool provided by this embodiment can save the driving force for rotating the driving member 21 in the process of disassembling the bearing 31 by using the interlocking action between the lock nut 6 and the driving member 21, so as to facilitate pulling out the bearing 31 from the through hole 40 and improve the disassembling efficiency.

As shown in fig. 3 and 4, one end of the second pull rod 5 is rotatably connected with a hook 7, the length of the hook 7 is larger than the inner diameter of the bearing 31 left in the foreign object 4 and is not larger than the outer diameter of the bearing 31, and the hook 7 can pass through the inner ring of the bearing 31 left in the foreign object 4 and then abut on the side of the bearing 31 far away from the bracket 20.

When the end part of the second pull rod 5 connected with the hook connector 7 extends into the bearing 31, because the length of the hook connector 7 is not larger than the outer diameter of the bearing 31, the hook connector 7 can rotate at the end part of the second pull rod 5 under the abutting action of the bearing 31 until the hook connector 7 is attached to one side of the shaft of the second pull rod 5, and at the moment, the hook connector 7 can pass through the inner ring of the bearing 31 and move to one side of the bearing 31 far away from the support 20. After the hook 7 is completely moved to the side of the bearing 31 away from the bracket 20, the abutting action of the bearing 31 on the hook 7 is eliminated, and the hook 7 can reversely rotate under the action of the self-gravity. The second pull rod 5 can then be pulled in a direction away from the bearing 31, and since the length of the hook 7 is greater than the inner diameter of the bearing 31 remaining in the foreign object 4, the hook 7 after the reverse rotation can abut on the side of the bearing 31 away from the bracket 20. When the second pull rod 5 is further pulled in a direction away from the bearing 31, the hook 7 on the second pull rod 5 can bring the bearing 31 to move together, so that the bearing 31 is pulled out of the through hole 40 of the foreign object 4.

As shown in fig. 4, a rotation shaft is inserted through the middle of the hook 7 in a direction perpendicular to the length direction of the hook 7. The end part of the second pull rod 5, which is rotatably connected with the hook connecting piece 7, is provided with a groove 50, the side wall of the groove 50 is provided with two through holes with opposite positions, and the rotating shaft penetrates through the two through holes of the groove 50 along the length direction perpendicular to the second pull rod 5.

In order to improve the structural stability of the second tie rod 5, a connection block 51 may be fixed at an end of the second tie rod 5 provided with a groove 50, the groove 50 being provided on the connection block 51.

As shown in fig. 4, the side of the hooking piece 7 away from the middle of the second draw bar 5 is a cambered surface.

The cambered surface facilitates the rotation of the catch 7 under the abutment action of the bearing 31, thereby facilitating the abutment of the catch 7 on the side of the shank of the second draw bar 5.

In this embodiment, the inner wall of the first through-hole 200 may be smooth.

The diameter of the first through hole 200 is not less than the external diameter of the external thread of the first pull rod 1, and when the diameter of the first through hole 200 is equal to the external diameter of the external thread of the first pull rod 1, in order to prevent the first through hole 200 from affecting the moving process of the first pull rod 1, the inner wall of the first through hole 200 is a smooth surface.

Further, the valve structure disassembling tool provided by the embodiment further comprises a cushion block, and the cushion block can be attached to the outer side of the groove bottom of the support 20.

Since the force between the bearing 31 caught in the through-hole 40 of the foreign object 4 and the inner wall of the through-hole 40 is large, the bearing 31 is not easily withdrawn from the through-hole 40, and thus, in order to facilitate the pulling out of the bearing 31 from the through-hole 40 of the foreign object 4, when the bearing 31 is removed, as shown in fig. 3, the support 20 when the valve body 30 is removed may be inverted so that the groove bottom of the support 20 is attached to the foreign object 4. If it is still difficult to pull the bearing 31 after the bracket 20 is inverted, the pad can be attached to the outside of the groove bottom of the bracket 20.

Further, a third through hole capable of being communicated with the second through hole 201 can be formed in the cushion block, and an inner thread matched with the outer thread of the second pull rod 5 is formed in the inner wall of the third through hole.

The cushion block is used for enhancing the strength of the bracket 20 and improving the supporting force of the bracket 20 on the second pull rod 5.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
