Description

Technical Field

[0001] The utility model relates to the field of extractors, in particular to an extractor. Background Art

[0002] The packing is a sealing filler between the valve stem and the valve cover. Its function is to ensure that the valve stem can move freely without leaking the medium in the valve. When the drainage pump is in operation, the rotation gap between the drive shaft and the pump seat will cause a lot of water leakage. After the graphite packing is installed in the stuffing box, the packing gland is adjusted to adjust the packing water seepage to ensure the safe and stable operation of the drainage pump. During the flood season, the water leakage of the power plant increased, the drainage pump was started frequently, the packing was seriously worn, and the shaft seal water seepage increased. In order to avoid flooding the plant and ensure the safe and stable operation of the drainage pump, the drainage pump packing needs to be replaced regularly. The gap of the drainage pump packing stuffing box is narrow, and the packing is installed in many layers, generally 5 layers. The closer the packing is to the bottom of the stuffing box, the more difficult it is to remove.

[0003] In the current technical means, the packing is replaced by rotating the soft connection tap and inserting it and forcibly pulling it out of the packing. However, this method is prone to cause the tap to break inside the packing when used in an incorrect manner, making it difficult to remove the packing; and in the process of pulling out the soft connection tap, the moment the tap breaks may hit the hand against fixed parts such as metal, causing personal injury; in addition, using the existing technology to replace the packing requires a lot of time and energy, and also seriously affects the work process of water pump maintenance. For this reason, a remover is proposed. Utility Model Content

[0034] Example 1

[0035] Reference Figure 1 and 2 , which is the first embodiment of the utility model, and this embodiment provides a take-out device.

[0036] The extractor includes an operating assembly 100 .

[0037] Specifically, the operating component 100 includes a first half ring 101 and a second half ring 102. The first half ring 101 and the second half ring 102 have the same structure and are relatively arranged. The first half ring 101 and the second half ring 102 are movably connected. The splicing arrangement of the first half ring 101 and the second half ring 102 can better adapt to the use scenario of the packing. In order to ensure normal use of the drainage pump during use, the two ends of the drainage pump cannot be opened, and the inside of the rotating shaft can only be entered from both sides. A complete ring cannot be nested on the rotating shaft. The splicing method can enter the interior of the drainage pump more quickly, and can be assembled after entering the interior of the drainage pump, so that the first half ring 101 and the second half ring 102 can be smoothly installed on the rotating shaft, which is convenient for staff to better To remove the packing, the first half ring 101 and the second half ring 102 are both provided with a grabbing piece 103. The setting of the grabbing piece 103 facilitates better insertion into the packing. When lifted upward, the packing can be effectively taken out of the drainage pump, avoiding the phenomenon of breakage of the operating component 100 or the packing during the lifting process, further ensuring the safety of the staff. The bottom of the first half ring 101 and the second half ring 102 are both connected with an auxiliary piece 105. The setting of the auxiliary piece 105 makes it convenient for the staff to drive the first half ring 101, the second half ring 102 and the grabbing piece 103 to rotate and press down in the drainage pump by operating the auxiliary piece 105, so that the grabbing piece 103 can smoothly penetrate into the interior of the packing, which saves time and effort in operation and improves work efficiency.

[0038] When in use, first install the two auxiliary parts 105 on the first half ring 101 and the second half ring 102 respectively, then remove the drainage pump shaft seal packing gland bolts, lift the gland and fix it on the transmission shaft water retaining ring, then put the first half ring 101 and the second half ring 102 into the drainage pump, with the end with the grabbing part 103 facing downward, and then combine the first half ring 101 and the second half ring 102 into a complete ring on the rotating shaft of the drainage pump through the fixing part 104, so that the first half ring 101 and the second half ring 102 with the grabbing part 103 are One side is aligned with the packing inside the drainage pump, and finally the auxiliary part 105 is operated with both hands to press down and rotate clockwise. The auxiliary part 105 drives the whole ring to rotate, and the grabbing part 103 on the whole ring penetrates into the packing and then slowly lifts the auxiliary part 105 upwards, and the packing is lifted together, and the packing on the grabbing part 103 can be removed. This can effectively avoid the breakage of the packing or the operating component 100 due to improper operation, as well as personal injury caused by the breakage, facilitates better operation by the staff, saves time and effort, and improves work efficiency.

[0039] Example 2

[0040] Reference Figure 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides a remover.

[0041] Specifically, four grabbing pieces 103 are provided and are respectively installed on the top of the first half ring 101 and the second half ring 102. The grabbing piece 103 is hook-shaped, and the end of the grabbing piece 103 is a piercing end 103a. The line formed by the piercing end 103a and the center of the other end of the grabbing piece 103 forms an angle α with the plane of the half ring where it is located, so that the first half ring 101 and the second half ring 102 can be effectively inserted into the packing in the drainage pump when they rotate downward, so that the first half ring 101 and the second half ring 102 are lifted upward, and the grabbing piece 103 is driven to move synchronously, thereby driving the packing on the grabbing piece 103 to move upward, so that the packing is removed from the drainage pump.

[0042] It is worth noting that: 30°<α<90, when the angle α is less than 30°, the piercing end 103a on the grabbing piece 103 is too close to the plane of the two half rings, resulting in that when the two half rings rotate and press down to drive the grabbing piece 103 to move downward, the piercing end 103a on the grabbing piece 103 cannot pierce the packing well, resulting in the inability to insert into the packing, affecting the normal removal of the packing; when the angle α is greater than 90°, the piercing end 103a on the grabbing piece 103 will be in a vertical or offset state with the plane of the two half rings, resulting in that when the two half rings rotate and press down to drive the grabbing piece 103 to move downward, after the piercing end 103a on the grabbing piece 103 pierces the packing, the piercing end 103a in the vertical state is pulled up by the two half rings, because the contact surface between the packing is reduced, thereby failing to effectively remove the packing. When the packing is taken out from the water pump, the use effect is not good. When the piercing end 103a which is larger than the vertical state moves downward, the piercing end 103a is directed upward, and cannot effectively pierce the packing and insert into the packing, thereby affecting the normal removal effect of the packing; only when 30°<α<90, the piercing end 103a on the grabbing piece 103 can more smoothly penetrate into the packing when pressed downward and rotated, ensuring that the grabbing piece 103 is in full contact with the packing, and increasing the contact surface between the grabbing piece 103 and the packing, so that when the grabbing piece 103 is pulled upward, the packing can be smoothly taken out of the drainage pump, and at the same time, the phenomenon of the packing or the grabbing piece 103 breaking during removal is avoided, which can effectively avoid personal injury caused by breakage, facilitate the staff to operate better, and save time and effort, thereby improving work efficiency.

[0043] Example 3

[0044] Reference Figure 1-4 , which is the third embodiment of the utility model. This embodiment provides a take-out device, which is easy to implement the working principle of the second embodiment in combination with the embodiment:

[0045] Specifically, the first half ring 101 and the second half ring 102 are both provided with a fixing part 104, and the fixing part 104 is composed of a pin 104a and a pin hole 104b. The pin 104a and the pin hole 104b are movably connected. Through the setting of the fixing part 104, the first half ring 101 and the second half ring 102 can be smoothly spliced ​​together after being placed in the drainage pump, so that the grasping parts 103 on the first half ring 101 and the second half ring 102 can be better rotated under force. When in use, the first half ring 101 and the second half ring 102 are connected to facilitate the removal of the packing. When not in use, the first half ring 101 and the second half ring 102 are disassembled to facilitate separate storage, reduce the storage area, and store more conveniently.

[0046] Preferably, the pin 104a is symmetrically arranged at the open end of the first half ring 101, and the pin hole 104b is symmetrically opened at the open end of the second half ring 102. The first half ring 101 and the second half ring 102 are spliced ​​into a circle through the cooperation between the pin 101a and the pin hole 104b, and are installed on the rotating shaft. They can be well positioned when moving up and down to avoid the phenomenon of the two half rings being offset during the descent process, thereby ensuring that the grabbing pieces 103 on the two half rings can be accurately aligned with the packing inside the drainage pump when descending, so that the grabbing pieces 103 can smoothly pierce the packing and be inserted into it.

[0047] Example 4

[0048] Reference Figure 1-4 , which is the fourth embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides a remover.

[0049] Specifically, the auxiliary component 105 is composed of a connecting rod 105a, a coupling rod 105b and an operating rod 105c. The connecting rod 105a and the operating rod 105c are fixed at both ends of the coupling rod 105b respectively. The connecting rod 105a is fixedly connected to the first half ring 101 or the second half ring 102. Through the setting of the coupling rod 105b, the connecting rod 105a is effectively connected to the operating rod 105c, thereby changing the contact position between both hands and the first half ring 101 and the second half ring 102, making it more time-saving, labor-saving and convenient for the staff to operate the first half ring 101 and the second half ring 102. The coupling rod 105b is arc-shaped, and the rotation direction is set opposite to the opening direction of the half ring where it is located, so that the connecting rod 105a and the operating rod 105c are not in the same horizontal state, and the installation length between the connecting rod 105a and the operating rod 105c The effective shortening makes the auxiliary component 105 better adapted for use in the drainage pump, making it safer for the staff to rotate the operating rod 105c to drive the connecting rod 105a to rotate, avoiding the auxiliary component 105 from colliding with the inside of the drainage pump during rotation due to its excessive length, thereby affecting the normal progress of the packing removal work. At the same time, it avoids the phenomenon that the staff's arm is injured due to the collision of the auxiliary component 105 during operation due to its excessive length. When the staff rotates the operating rod 105c, under the action of the connecting rod 105b, the connecting rod 105c moves synchronously, so that when the connecting rod 105a rotates, it can drive the two half rings to rotate synchronously, thereby driving the grabbing parts 103 on the two half rings to rotate, thereby realizing the removal of the packing in the drainage pump, and avoiding the auxiliary component 105 from breaking due to excessive force.

[0050] It is worth noting that the connecting rod 105a is fixed at the midpoint of the half ring where it is located, and the connecting rod 105a and the operating rod 105c are vertically arranged, which effectively reduces the installation space of the connecting rod 105a and the operating rod 105c, leaving operating space for the staff to rotate the operating rod 105c, and facilitating the staff to operate the auxiliary component 105 on the inner wall of the drainage pump to perform a series of actions such as rotating, pressing, and lifting, thereby avoiding injuries to the staff when operating the auxiliary component 105, making the operation safer, making it easier for the staff to operate the two half rings, and can effectively drive the two half rings to rotate and press, and the connecting rod 105a is threadedly connected to the two half rings, so that when not in use, the connecting rod 105a can be removed from the first half ring 101 and the second half ring 102, saving storage space and making storage more convenient.

[0051] After the first half ring 101 and the second half ring 102 successfully enter the interior of the drainage pump, the pin 104a on the first half ring 101 is inserted into the pin hole 104b on the second half ring 102, so that the first half ring 101 and the second half ring 102 effectively form a complete ring on the rotating shaft, and then the operating rod 105c is rotated and pressed down. Under the action of the operating rod 105c, the connecting rod 105a is synchronously rotated and pressed down, thereby driving the entire ring on the connecting rod 105a to rotate and press down. , and then the grabbing piece 103 on the whole ring rotates downward to pierce the packing and insert into the packing. When the grabbing piece 103 is completely inserted into the packing, the operating rod 105c is lifted upward, thereby driving the connecting rod 105b and the connecting rod 105a at one end of the operating rod 105c to move upward. Driven by the connecting rod 105a, the whole ring and the grabbing piece 103 on the whole ring move upward. Under the action of the grabbing piece 103, the packing moves upward, thereby achieving the effect of removing the packing from the drainage pump.
