Description

Technical Field

[0001] The invention belongs to the technical field of pin removers, and in particular relates to a pin remover capable of clamping pins of different sizes. Background Art

[0002] Thermal power generation uses the heat energy obtained from burning fuels such as coal, petroleum and its products, natural gas, etc. to generate electricity. Thermal power plant equipment is usually large in size, so most thermal power plant equipment is installed and fixed with locating pins. When it is necessary to inspect and maintain the thermal power plant equipment, tools are needed to remove the locating pins.

[0003] When the existing pin remover is used, in order to quickly and conveniently clamp and fix the locating pins on the thermal power plant equipment, it is usually only installed with two sets of symmetrically designed clamping blocks. Although it can clamp the locating pins, when the size of the locating pins is too large, the clamping range of the two sets of clamping blocks is limited, resulting in the large locating pins being easily fallen off during the pin removal work, thereby failing to meet the user's usage needs. Summary of the invention

[0004] The object of the present invention is to provide a pin remover capable of clamping different-sized locking pins, so as to solve the problem that the pin remover of a thermal power plant proposed in the above-mentioned background technology cannot clamp and fix the positioning pins of different sizes.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pin remover capable of clamping different-sized bayonet pins, comprising an inner sleeve and a mounting shell, the outer side of the inner sleeve being connected to an outer sleeve via a slider, one side of the inner sleeve being connected to a screw rod via a bearing, the side of the screw rod away from the inner sleeve being connected to a driving motor via a coupling, the outer side of the driving motor being sleeved with a movable housing, both ends of the movable housing being installed with pulleys, and the mounting shell being sleeved on the outer side of the movable housing;

[0006] A transmission motor is installed on one side of the inner sleeve through a groove, and the output end of the transmission motor is connected to a driving shaft through a coupling, and one side of the driving shaft is connected to a bevel gear set, and a bidirectional screw is connected through the middle of the bevel gear set, and both ends of the bidirectional screw are sleeved with transverse clamping blocks, and one end of the transverse clamping block is installed with a connecting block, and the middle of the connecting block is connected with a sliding column through a bevel groove, and one side of the sliding column is connected to a vertical clamping block, and first sliding blocks are installed at both ends of the transverse clamping block and the vertical clamping block.

[0007] Preferably, a push plate is installed on the same side of the inner sleeve away from the screw rod.

[0008] Preferably, a fixing plate is provided on one side of the push plate, and a telescopic plate is installed on the bottom of the fixing plate.

[0009] Preferably, a movable spring is connected between the telescopic plate and the groove of the outer sleeve, and a second sliding block is connected to one side of the outer sleeve through a sliding groove.

[0010] Preferably, a collection box is connected between the two groups of the second sliding blocks, and a card block is inserted into one side of the second sliding block.

[0011] Preferably, a threaded rod penetrating the inner sleeve is connected to the bottom of the clamping block, and a fixing block is sleeved on the outer side of the threaded rod.

[0012] Preferably, one side of the movable housing is connected to a first baffle via a rotating shaft, one side of the first baffle is plugged with an insertion rod, a movable block is installed on the outer side of the insertion rod, and a telescopic spring is connected between the insertion rod and the movable block.

[0013] Preferably, one side of the mounting shell is connected to a second baffle via a rotating shaft.

[0014] Preferably, a return spring is installed in the middle of the second baffle through a groove, and a telescopic rod is installed at the bottom of the return spring.

[0015] Preferably, the bottom of the telescopic rod is connected to a clamping rod penetrating the second baffle, and a protrusion is installed at the bottom of the clamping rod.

[0016] A technical effect of the present invention is:

[0017] In the embodiment of the present application, when the pin remover that can clamp pins of different sizes is in use, the transmission motor and the drive shaft can be used to drive the bevel gear set and the bidirectional screw to rotate. The rotation of the bidirectional screw will drive the two groups of lateral clamping blocks to move in opposite directions through the first sliding block. The movement of the lateral clamping blocks will cause the sliding column to slide along the bevel groove through the connecting block. With the cooperation of the bevel groove of the connecting block and the sliding column, the vertical clamping block can be driven to move. The two groups of lateral clamping blocks and the two groups of vertical clamping blocks can clamp the four sides of the locating pin at the same time, and the clamping effect of locating pins of different sizes can also be met. This is the use feature of the pin remover that can clamp pins of different sizes.

[0018] Moreover, when the pin remover capable of clamping pins of different sizes is required to remove the pins of the thermal power plant equipment, it is only necessary to connect the positioning pin to the inside of the inner sleeve, and then the positioning pin can be clamped and limited by the two groups of horizontal clamping blocks and the two groups of vertical clamping blocks in the inner sleeve. Not only can the four sides of the positioning pin be clamped at the same time, but also the positioning pins of different sizes can be clamped and limited, so that the removal effect is better.

[0019] Furthermore, when the pin remover capable of holding pins of different sizes needs to collect the positioning pins after disassembly, it only needs to pull the positioning pin toward the inside of the outer sleeve through the inner sleeve, and at the same time, the inner sleeve will push the telescopic plate toward the groove at the bottom of the outer sleeve through the push plate and the fixed plate. At this time, there is no obstruction from the telescopic plate. After the positioning pin is released, the positioning pin will fall into the collection box at the bottom of the outer sleeve, so that it is convenient to collect the disassembled positioning pins.

[0020] In addition, when the pin remover that can clamp pins of different sizes needs to maintain the driving motor inside the pin remover, the second baffle of the clamping rod can be pulled up so that the clamping rod does not limit the second baffle. Then the second baffle can be quickly opened and the movable shell can be pulled out from the inside of the mounting shell. At the same time, the insertion rod is pulled to one side so that the insertion rod moves out from one side of the first baffle and the insertion rod is pulled downward through the movable block. At this time, the first baffle is rotated upward again. Then the driving motor in the movable shell can be quickly maintained, so that the entire pin remover can work normally.

[0037] See also Figure 1 , Figure 2 The present invention provides a technical solution: a pin remover capable of clamping different sizes of pins, comprising an inner sleeve 1 and a mounting shell 34, the outer side of the inner sleeve 1 is connected to an outer sleeve 2 via a slider, one side of the inner sleeve 1 is connected to a screw rod 3 via a bearing, the side of the screw rod 3 away from the inner sleeve 1 is connected to a driving motor 4 via a coupling, the outer side of the driving motor 4 is sleeved with a movable housing 5, both ends of the movable housing 5 are equipped with pulleys 6, and the mounting shell 34 is sleeved on the outer side of the movable housing 5;

[0038] A transmission motor 7 is installed on one side of the inner sleeve 1 through a groove, and the output end of the transmission motor 7 is connected to a driving shaft 8 through a coupling, and a bevel gear set 9 is connected to one side of the driving shaft 8. A bidirectional screw 10 is connected through the middle of the bevel gear set 9, and both ends of the bidirectional screw 10 are sleeved with a transverse clamping block 11, and a connecting block 12 is installed at one end of the transverse clamping block 11, and a sliding column 13 is connected to the middle of the connecting block 12 through a bevel groove, and a vertical clamping block 14 is connected to one side of the sliding column 13, and first sliding blocks 15 are installed at both ends of the transverse clamping block 11 and the vertical clamping block 14, and the vertical clamping block 14 and the vertical clamping block 14 are slidably connected to the inside of the inner sleeve 1 through the first sliding block 15.

[0039] During specific implementation, when the pin remover capable of clamping different-sized card pins needs to clamp the positioning pin, the inner sleeve 1 can be sleeved on the outer side of the positioning pin, and the positioning pin is located between the two groups of horizontal clamping blocks 11 and the two groups of vertical clamping blocks 14. At this time, the transmission motor 7 can be started, so that the transmission motor 7 drives the driving shaft 8 to rotate through the coupling. One end of the driving shaft 8 is connected with a bevel gear set 9, and the bevel gear set 9 is connected by two mutually meshing bevel gears. One bevel gear is connected to the driving shaft 8, and the other bevel gear is connected to the bidirectional screw 10. Under the cooperation of the driving shaft 8, the bidirectional screw 10 will be driven to rotate through the bevel gear set 9. Both ends of the bidirectional screw 10 are sleeved with horizontal clamping blocks 11, and the horizontal clamping blocks 11 and the bidirectional screw 10 are threadedly connected. At the same time, both ends of the horizontal clamping block 11 are slidably connected to the inside of the inner sleeve 1 through the first sliding block 15. Therefore, under the cooperation of the first sliding block 15, when the bidirectional screw 10 rotates, the two groups of horizontal clamping blocks 11 will move closer to each other;

[0040] A connecting block 12 is installed at one end of the horizontal clamping block 11, and a sliding column 13 is connected to the middle of the connecting block 12 through an inclined groove. Since the sliding column 13 is installed on one side of the vertical clamping block 14, and the two ends of the vertical clamping block 14 are also slidably connected to the inside of the inner sleeve 1 through the first sliding block 15, the vertical clamping block 14 can only slide horizontally along the inner wall of the inner sleeve 1, so that the vertical height position of the sliding column 13 remains unchanged. When the horizontal clamping block 11 drives the inclined groove in the connecting block 12 to move, the sliding column 13 will slide along the inclined groove of the connecting block 12. The groove is an inclined structure. When the sliding column 13 slides along the inclined groove of the connecting block 12, it will drive the vertical clamping block 14 to move. Since the extension lines of the inclined grooves in the four groups of connecting blocks 12 intersect with the center line of the inner sleeve 1, the two groups of horizontal clamping blocks 11 and the vertical clamping blocks 14 move synchronously in opposite directions. When the two groups of horizontal clamping blocks 11 move toward each other, the two groups of vertical clamping blocks 14 will also move toward each other. When the two groups of horizontal clamping blocks 11 move away from each other, the two groups of vertical clamping blocks 14 will also move away from each other. The two groups of vertical clamping blocks 14 and the two groups of horizontal clamping blocks 11 can be used to clamp positioning pins of different sizes on all sides.

[0041] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig.10It can be seen that when in use, the locating pins can be connected between the two groups of horizontal clamps 11 and the two groups of vertical clamps 14, and then the two-way screw 10 drives the two groups of horizontal clamps 11 to move through the cooperation of the transmission motor 7, the drive shaft 8, and the bevel gear group 9. The movement of the horizontal clamp 11 will drive the sliding column 13 and the vertical clamp 14 to move through the connecting block 12 and the bevel groove. With the cooperation of the horizontal clamp 11 and the vertical clamp 14, the locating pins of different sizes can be clamped and fixed.

[0042] A push plate 16 is installed on the same side of the inner sleeve 1 away from the screw rod 3, and a fixed plate 17 is provided on one side of the push plate 16. A telescopic plate 18 is installed at the bottom of the fixed plate 17. A movable spring 19 is connected between the telescopic plate 18 and the groove of the outer sleeve 2. A second sliding block 20 is connected to one side of the outer sleeve 2 through a sliding groove, and a collecting box 21 is connected between the two groups of second sliding blocks 20. A card block 22 is inserted into one side of the second sliding block 20, and a threaded rod 23 passing through the inner sleeve 1 is connected to the bottom of the card block 22. A fixed block 24 is sleeved on the outer side of the threaded rod 23, and the fixed block 24 is installed at the bottom of the outer sleeve 2.

[0043] When it is implemented specifically, the pin remover that can clamp the pins of different sizes can slide the collection box 21 to the bottom of the outer sleeve 2 through the second sliding blocks 20 on both sides of the collection box 21 when it is needed to collect the removed positioning pins. When the collection box 21 is slid to the end of the slide groove of the outer sleeve 2, the threaded rod 23 can be rotated. Since the threaded rod 23 and the fixed block 24 are threadedly connected, and the threaded rod 23 is connected to the block 22 through a bearing, the threaded rod 23 is guided by the groove of the outer sleeve 2 on the block 22, so that the threaded rod 23 will drive the block 22 to move when it rotates, and the block 22 is plugged into one side of the second sliding block 20. At this time, the collection box 21 can be stably installed at the bottom of the outer sleeve 2.

[0044] Then, the positioning pin can be pulled into the inner part of the outer sleeve 2 through the inner sleeve 1, and a push plate 16 is installed on one side of the inner sleeve 1, and a telescopic plate 18 is installed at the bottom of the outer sleeve 2 through a groove, and a fixed plate 17 is installed on the top of the telescopic plate 18. When the inner sleeve 1 moves into the inner part of the outer sleeve 2, the push plate 16 will push the fixed plate 17 to move, and the telescopic plate 18 at the bottom will be driven to move into the groove of the outer sleeve 2 through the fixed plate 17. At the same time, the telescopic plate 18 will squeeze the movable spring 19 in the groove of the outer sleeve 2. When the telescopic plate 18 is completely retracted into the groove of the outer sleeve 2, it can be The through hole at the bottom of the outer sleeve 2 is opened, and then the positioning pin is released by the transmission motor 7. At this time, the positioning pin will fall into the collection box 21 through the through hole at the bottom of the outer sleeve 2 due to the action of gravity, so as to facilitate the collection of the positioning pin. After the disassembly is completed, the inner sleeve 1 can be pushed to the outside of the outer sleeve 2, so that the push plate 16 does not squeeze the telescopic plate 18 through the fixed plate 17, and then the telescopic plate 18 will be reset by the movable spring 19, thereby covering the through hole at the bottom of the outer sleeve 2, so that the positioning pin in the collection box 21 will not fall out through the through hole of the outer sleeve 2.

[0045] See also Figure 1 , Figure 2 , Figure 5 Figure 8 and Fig. 9 It can be seen that when in use, the inner sleeve 1 can be pulled toward the inside of the outer sleeve 2, so that the push plate 16 pushes the telescopic plate 18 to one side through the fixed plate 17. At this time, the telescopic plate 18 does not block the through hole at the bottom of the outer sleeve 2, and then the horizontal clamping block 11 and the vertical clamping block 14 are loosened. At this time, under the action of gravity, the positioning pins will fall into the collection box 21, thereby facilitating the collection of the positioning pins.

[0046] One side of the movable shell 5 is connected to a first baffle 25 through a rotating shaft, and a plug rod 26 is inserted into one side of the first baffle 25. A movable block 27 is installed on the outer side of the plug rod 26. A telescopic spring 28 is connected between the plug rod 26 and the movable block 27. One side of the mounting shell 34 is connected to a second baffle 29 through a rotating shaft, and a return spring 30 is installed in the middle of the second baffle 29 through a groove. A telescopic rod 31 is installed at the bottom of the return spring 30. The bottom of the telescopic rod 31 is connected to a clamping rod 32 that passes through the second baffle 29, and a protrusion 33 is installed at the bottom of the clamping rod 32. The movable block 27 is slidably connected to the side of the movable shell 5.

[0047] When the drive motor 4 in the movable housing 5 needs to be maintained, the clamping rod 32 passing through one side of the second baffle plate 29 can be pushed upward, so that the clamping rod 32 drives the protrusion 33 at the bottom to move out of the groove of the mounting shell 34. Without the clamping rod 32 and the protrusion 33 docking in the groove of the mounting shell 34, the second baffle plate 29 can be rotated upward by the rotating shaft, and then the movable housing 5 and the drive motor 4 can be pulled out of the mounting shell 34 by the pulley 6. At this time, the insertion rod 26 is pulled to one side of the first baffle plate 25, so that the insertion rod 26 is not inserted into one side of the first baffle plate 25, and then the movable block 27 is pulled downward along the sliding groove on the side of the movable housing 5, so that the movable block 27 and the insertion rod 26 do not limit the first baffle plate 25, so that the first baffle plate 25 can be turned upward, and the drive motor 4 in the movable housing 5 can be maintained without the obstruction of the first baffle plate 25.

[0048] On the contrary, the first baffle 25 can be rotated to one side of the movable block 27, and then the movable block 27 is pushed upward. At this time, the plug rod 26 is released, and the plug rod 26 will be reset by the telescopic spring 28 and inserted into the groove of the first baffle 25, so that the first baffle 25 can be fixed. At the same time, the movable shell 5 is pushed into the mounting shell 34, and then the second baffle 29 is rotated downward, and the clamping rod 32 and the protrusion 33 passing through the middle of the second baffle 29 are connected to the groove of the mounting shell 34. After the clamping rod 32 is released, the clamping rod 32 will drive the clamping rod 32 and the protrusion 33 to move downward through the resetting action of the telescopic rod 31 and the reset spring 30, and the second baffle 29 can be fixed by the clamping rod 32 and the protrusion 33, thereby ensuring that the entire disassembler can work normally.

[0049] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when in use, the second baffle 29 and the first baffle 25 can be quickly flipped upward according to the use requirements, and the drive motor 4 in the movable housing 5 can be quickly maintained at this time.

[0050] To sum up, when the pin remover that can clamp pins of different sizes is in use, the inner sleeve 1 can be docked to the outside of the locating pin that needs to be removed, and then the locating pin is clamped by the horizontal clamping block 11 and the vertical clamping block 14. At this time, the drive motor 4 is started, and the drive motor 4 will drive the screw rod 3 to rotate through the coupling. The screw rod 3 and the outer sleeve 2 are threadedly connected, and the screw rod 3 is connected to one side of the inner sleeve 1 through a bearing. At this time, the drive motor 4 will drive the inner sleeve 1 to shrink toward the inside of the outer sleeve 2 through the screw rod 3, and at the same time, the drive motor 4 will slide the movable outer shell 5 and the pulley 6 along the mounting shell 34, so as to facilitate and quickly remove the locating pin from the generator set through the inner sleeve 1. This is the use feature of the pin remover that can clamp pins of different sizes. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
