Description

Technical Field

[0001] This utility model relates to the field of chemical pump repair technology, specifically an auxiliary device for chemical pump repair. Background Technology

[0002] Chemical pumps typically have various parts, such as couplings (back-to-back wheels), gears, or pulleys, installed on their rotating parts with interference fits. After prolonged operation, these parts often become difficult to disassemble due to corrosion, jamming, or excessive tightness. Therefore, tools such as pullers are needed to assist in the maintenance of chemical pumps.

[0003] Currently, pullers are mainly divided into two types: external pullers and internal pullers. External pullers have inward-curved claws and are mainly used to disassemble bearings, gears, pulleys, couplings and other parts on the shaft. Internal pullers have outward-curved claws and are mainly used to disassemble bearings, bushings and other parts that are tightly fitted in the hole. However, external and internal pullers are not interchangeable. Therefore, we propose an auxiliary device for the maintenance of chemical pumps. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the maintenance of chemical pumps, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation in the specification, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Please see Figures 1-3 In this embodiment of the utility model, an auxiliary device for chemical pump maintenance includes a nut 1, a screw 9 is fitted inside the nut 1, a handle 10 is installed on the top of the screw 9, and a top cone 11 is rotatably installed at the bottom of the screw 9. Two square rods 2 are symmetrically fixedly connected to the outer walls on both sides of the nut 1. A pull rod 3 is slidably sleeved on the square rod 2. A through rod 16 is installed on both the pull rod 3 and the top cone 11. A support rod 18 is sleeved on the square rod 2. An installation groove 5 is provided through the outer wall of the pull rod 3 near the bottom end. An L-shaped hook 7 is rotatably installed in the installation groove 5 through a pin 6.

[0022] This utility model, by adopting the above-mentioned solution, such as Figure 1 As shown, when disassembling the bearing 20 that is tightly fitted in the hole, simply rotate the L-shaped hook 7 in the mounting groove 5 until the claws of the L-shaped hook 7 face outwards, then pass the bottom end of the pull rod 3 through the bearing 20 until the L-shaped hook 7 is below the bearing 21, slide the pull rod 3 on the square rod 2 until the pull rod 3 is in contact with the inner wall of the bearing 21, then place the bottom end of the support rod 18 against the bearing seat, and rotate the screw 9 on the nut 1 through the handle 10. Since the top cone 11 and the pull rod 3 are passed through by the through rod 16 at the same time, when the top cone 11 moves upward under the drive of the screw 9, it will drive the two pull rods 3 to move upward at the same time, thereby pulling the bearing 20 out of the bearing seat through the two L-shaped hooks 7. The operation is simple and convenient.

[0023] like Figure 2As shown, when disassembling the bearing 20 that is tightly fitted on the rotating shaft 21, simply remove the through rod 16 from the pull rod 3 and the top cone 11, then rotate the L-shaped pull rod 7 in the mounting groove 5 until the claw of the L-shaped pull hook 7 faces inward, then slide the pull rod 7 on the square rod 2 until the two pull rods 7 are tightly attached to both sides of the bearing 20, and then rotate the screw 9 on the nut 1 by the handle 10 to move the top cone 11 downward to the end of the rotating shaft 21. Then, simply drive the top cone 11 downward to use the reaction force to pull the bearing 20 off the rotating shaft 21.

[0024] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, the top of the top cone 11 is provided with a slot 12, the bottom end of the screw 9 is located in the slot 12, the outer wall of the screw 9 located in the slot 12 is provided with an annular groove 13, and a guide pin 14 is fixedly installed on the outer wall of the top cone 11, one end of the guide pin 14 is located in the annular groove 13.

[0025] By cooperating with the guide pin 14 and the annular groove 13, the bottom end of the screw 9 can be restricted within the slot 12, while the top cone 11 can still rotate at the bottom end of the screw 9.

[0026] Specific combination Figure 2 In one embodiment of this utility model, a magnet 8 is embedded and fixedly installed in the mounting groove 5. By setting the magnet 8, the hook claw of the L-shaped hook 7 located in the mounting groove 5 can be attracted to prevent the L-shaped hook 7 from rotating in the mounting groove 5 without human operation.

[0027] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, the pull rod 3 is provided with an opening groove 4 that matches the square rod 2, and the square rod 2 passes through the corresponding opening groove 4. The support rod 18 is provided with a third through hole 19 that matches the square rod 2. The setting of the snap fastener 4 and the third through hole 19 facilitates the installation of the pull rod 3 and the square rod 2 on the square rod 2.

[0028] Specific combination Figure 1 In one embodiment of the present invention, the outer wall of the pull rod 3 is provided with a second through hole 17 that is adapted to the through rod 16, and the outer wall of the top cone 11 is provided with a first through hole 15 that is adapted to the through rod 16.

[0029] The first through hole 15 and the second through hole 17 facilitate the assembly and disassembly of the through rod 16 on the top cone 11 and the pull rod 3.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
