Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of positioning device technology, and more specifically, to a sheath installation auxiliary positioning device. Background Technology

[0002] In industrial production, slurry pumps are a key piece of equipment widely used for conveying slurries containing solid particles. However, a pressing problem exists in the actual operation of slurry pumps: the rear sheath cannot achieve a perfect fit with the pump body, and the front sheath cannot fit perfectly with the pump cover.

[0003] The rear and front sheaths of a slurry pump play crucial roles in protecting the inner walls of the pump body and pump cover, respectively. Their tight fit with the pump body and pump cover is essential for the efficient and stable operation of the slurry pump. However, in practice, gaps often exist between the rear sheath and the pump body, and between the front sheath and the pump cover.

[0004] The existence of these gaps prevents the rear sheath and pump body, as well as the front sheath and pump cover, from being fully positioned. During slurry pump operation, the lack of precise positioning can cause slight displacement and wobbling of the rear and front sheaths, accelerating their wear and shortening their service life. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a sleeve installation auxiliary positioning device, which solves the technical problem in the prior art that there is a gap between the sleeve of the slurry pump and the pump body and pump cover after the slurry pump is installed.

[0014] For example, in a sleeve installation auxiliary positioning device provided in at least one embodiment of this disclosure, the connecting rod is a screw rod and the first slot is a threaded groove.

[0015] For example, in at least one embodiment of the present disclosure, a sheath installation auxiliary positioning device is provided, wherein the first extension further has a third slot, the third slot and the first slot are arranged sequentially in the vertical direction, the first slot and the third slot are in communication, the connecting rod is vertically slidably disposed in the first slot and the third slot, and further includes:

[0016] A slider is slidably mounted on the connecting rod. The slider is configured to slide out of the connecting rod and then engage with the third slot.

[0017] For example, in at least one embodiment of the present disclosure, a sheath installation auxiliary positioning device is provided, wherein the connecting rod has a sliding hole arranged in a vertical direction, and there are two sliders, which are slidably disposed on the connecting rod in opposite directions, and the device further includes:

[0018] A slide bar is slidably disposed within the slide hole. The slide bar has an insertion portion configured to insert or uninsert between two sliders. After the insertion portion is inserted between two sliders, the two sliders are engaged in the third slot.

[0019] For example, in at least one embodiment of this disclosure, a sheath installation auxiliary positioning device further includes:

[0020] An elastic element is disposed at both ends on the two sliders respectively, and the elastic element is used to provide a force to bring the two sliders closer together.

[0021] For example, in a sleeve installation auxiliary positioning device provided in at least one embodiment of this disclosure, the locking member has a plurality of locking members, the second sleeve body is used to be disposed on the pump cover, the pump cover also has a first extension, the second sleeve body also has a second extension, and the locking member is used to connect the first extension and the second extension.

[0022] For example, in a sheath installation auxiliary positioning device provided in at least one embodiment of this disclosure, two second extensions are located between two first extensions.

[0023] The beneficial effects of the embodiments disclosed herein are as follows:

[0024] This disclosure provides a simple and effective positioning and installation method.

[0039] Example 1

[0040] like Figures 1-2 As shown, it illustrates a sheath installation auxiliary positioning device in one embodiment of the present disclosure. The first sheath body 1 is disposed inside the pump body 2. The pump body 2 has a first groove 21. The first sheath body 1 has a first protrusion 11. The first protrusion 11 is used to snap into the first groove 21. After the first protrusion 11 is snapped into the first groove 21 for positioning, it is used to place the first sheath body 1 on the pump body 2. The clip 5 is used to connect the first protrusion 11 and the pump body 2.

[0041] For example, such as Figure 1 As shown, in actual operation, the first sheath body 1 is first placed inside the pump body 2, so that the first protrusion 11 on the first sheath body 1 is aligned with the first groove 21 of the pump body 2. Then, the first protrusion 11 is snapped into the first groove 21 to achieve initial positioning. Next, the clip 5 is used to connect the first protrusion 11 and the pump body 2 to ensure that the first sheath body 1 is installed on the pump body 2. For example, on an industrial water pump production line, workers follow these steps when assembling the pump body 2 and the first sheath body 1.

[0042] This design provides a simple and effective positioning and installation method. The snap-fit ​​positioning of the first protrusion 11 and the first groove 21 can quickly determine the installation position of the first sheath body 1 on the pump body 2, improving installation efficiency. The use of the clip 5 further enhances the stability of the connection, preventing the first sheath body 1 from shifting or loosening during the operation of the pump body 2, thus ensuring the normal operation of the pump body 2.

[0043] In some examples, the pump body 2 has a first extension 22, and a first groove 21 is located on the first extension 22; the first sheath body 1 has a second extension 12, and a first protrusion 11 is located on the second extension 12. The first extension 22 and the second extension 12 are arranged in parallel, and the clip 5 is used to connect the first extension 22 and the second extension 12.

[0044] For example, such as Figure 2As shown, both the pump body 2 and the first sheath body 1 are volute-shaped. A first extension 22 is designed at the outermost edge of the circumference of the pump body 2, and a second extension 12 is designed at the outermost edge of the circumference of the first sheath body 1, ensuring that the first extension 22 and the second extension 12 are arranged parallel to each other. When the clip 5 is installed, the first extension 22 and the second extension 12 are fitted together, thereby making the pump body 2 and the first sheath body 1 fit together. When the first sheath body 1 is placed inside the pump body 2, with the first extension 22 and the second extension 12 parallel, the clip 5 connecting the first extension 22 and the second extension 12 will not affect the fit between the pump body 2 and the first sheath body 1. The first protrusion 11 is located on the side of the first extension 22 near the second extension 12, and the opening of the first groove 21 is located on the side of the second extension 12 near the first extension 22. When the first sheath body 1 is placed inside the pump body 2, the first protrusion 11 and the first groove 21 are aligned, and the first protrusion 11 is engaged with the first groove 21. Then, the first protrusion 11 and the second extension 12 are connected using the clip 5.

[0045] The parallel arrangement of the first extension 22 and the second extension 12 makes the engagement between the first protrusion 11 and the first groove 21 more precise, and also provides a more stable structural foundation for the connection of the clip 5. This design reduces errors during installation and further enhances the stability of the connection between the first sheath body 1 and the pump body 2.

[0046] In some examples, the first extension 22 has a first slot 221, and the first protrusion 11 has a second slot 121. The clip 5 connects the first extension 22 and the second extension 12 through the first slot 221 and the second slot 121. The opening directions of the first slot 221 and the second slot 121 are both arranged along the installation direction of the first sheath body 1, which facilitates the installation of the device.

[0047] For example, such as Figure 2 As shown, when the first extension 22 and the second extension 12 are aligned parallel to each other and the first protrusion 11 is engaged with the first groove 21, a portion of the clip 5 is aligned with the first slot 221 of the first extension 22, and the other portion is aligned with the second slot 121 of the first protrusion 11. Then, the clip 5 is inserted through the first slot 221 and the second slot 121 to connect the first extension 22 and the second extension 12. For example, in the production of some small water pumps, workers can use simple tools to assist in the insertion of the clip 5.

[0048] The first slot 221 and the second slot 121 provide guidance for the connection of the clip 5, making the installation of the clip 5 more accurate and convenient. This connection method enhances the connection strength between the first extension 22 and the second extension 12, thereby improving the stability of the connection between the first sheath body 1 and the pump body 2.

[0049] In some examples, the card plate 51 is used to be disposed in the second card slot 121; one end of the connecting rod 52 is disposed on the card plate 51, and the other end is used to be disposed in the first card slot 221.

[0050] For example, such as Figure 2 As shown, first, place the clamping plate 51 into the second slot 121 of the first protrusion 11, ensuring that the clamping plate 51 fits the second slot 121. Then, fix one end of the connecting rod 52 onto the clamping plate 51, usually by welding, threaded connection, or other methods. Finally, insert the other end of the connecting rod 52 into the first slot 221 of the first extension 22 of the pump body 2 to complete the installation of the clamping component 5. For example, in the production of some custom water pumps, workers will select a suitable clamping plate 51 and connecting rod 52 according to design requirements and install them according to the above steps. The clamping plate 51 is arranged parallel to the first extension 22 to ensure that the connecting rod 52 is installed securely. The clamping plate 51 has a long slot, through which the connecting rod 52 passes and is clamped onto the clamping plate 51.

[0051] The combined design of the locking plate 51 and the connecting rod 52 makes the structure of the locking piece 5 more reasonable and flexible. The locking plate 51 can better cooperate with the second locking slot 121, increasing the contact area between the locking piece 5 and the first protrusion 11 and improving the stability of the connection. The connecting rod 52 provides the necessary length and support for the connection between the locking piece 5 and the first extension 22, facilitating the installation operation.

[0052] In some examples, the connecting rod 52 is a screw, and the first slot 221 is a threaded groove.

[0053] For example, such as Figure 2 As shown, since the connecting rod 52 is a screw and the first slot 221 is a threaded groove, after connecting one end of the screw to the card plate 51, the screw is screwed into the first slot 221 by rotating the screw until the screw and the first slot 221 are tightly fitted.

[0054] The screw and threaded groove provide excellent fastening and adjustability. Rotating the screw allows for precise control of the connection between the locking piece 5 and the first protrusion 11, ensuring a tight fit. Furthermore, this connection method is convenient for disassembly and maintenance; simply reverse the screw rotation.

[0055] Example 2

[0056] In some examples, the first extension 22 also has a third slot 222, which is arranged in sequence with the first slot 221 in the vertical direction. The third slot 222 communicates with the first slot 221. The connecting rod 52 is vertically slidably disposed in the first slot 221 and the third slot 222. The slider 6 is laterally slidably disposed on the connecting rod 52. The slider 6 is configured to slide into or out of the connecting rod 52 after sliding out of the connecting rod 52. The slider 6 is configured to be engaged in the first slot 221 after sliding out of the connecting rod 52.

[0057] For example, such as Figure 4 As shown, firstly, one end of the connecting rod 52 is slid into the first slot 221, and the other end is set on the retaining plate 51. After the connecting rod 52 slides to a suitable position in the first slot 221, the slider 6 is operated to slide laterally. For example, there is a spring between the slider 6 and the connecting rod 52. After reaching the suitable position, the spring can automatically push the slider 6 out, allowing it to slide into the third slot 222. Due to the limitation of the third slot 222, the connecting rod 52 cannot be pulled out, thus fixing the retaining plate 51. If it is necessary to disassemble the retaining piece 5, the slider 6 is slid out of the third slot 222 and slid into the connecting rod 52. For example, during the regular maintenance of the water pump, the worker can follow these steps to install and disassemble the retaining piece 5. The connecting rod 52 slides along the depth direction of the first slot 221, and the slider 6 slides along the width direction of the third slot 222. The thickness of the slider 6 is the same as the depth of the third slot 222, that is, after the slider 6 slides into the third slot 222, the connecting rod 52 will not be pulled out of the first slot 221.

[0058] After the slider 6 slides into the third slot 222, it prevents the connecting rod 52 from sliding vertically within the first slot 221, further enhancing the connection stability between the clip 5 and the first extension 22. The design of the slider 6, which allows the connecting rod 52 to slide in and out, makes the installation and removal of the clip 5 more convenient, improving maintenance efficiency.

[0059] In some examples, the connecting rod 52 has a sliding hole 521 arranged in the vertical direction, and there are two sliders 6. The two sliders 6 are slidably arranged on the connecting rod 52 in opposite directions. The sliding rod 7 is slidably arranged in the sliding hole 521. The sliding rod 7 has an insertion part 71 for inserting between the two sliders 6. After the insertion part 71 is inserted between the two sliders 6, the two sliders 6 move away from each other and are then locked into the third slot 222.

[0060] For example, such as Figure 4As shown, after the connecting rod 52 is installed in the first slot 221 and the retaining plate 51 is installed in the second slot 121, the sliding rod 7 is inserted into the sliding hole 521 of the connecting rod 52. As the sliding rod 7 is inserted, the insertion part 71 of the sliding rod 7 gradually inserts between the two sliders 6, causing the two sliders 6 to move away from each other under the action of the insertion part 71. When the sliders 6 slide out of the connecting rod 52 and into the third slot 222, the retaining member 5 is fixed. During disassembly, the sliding rod 7 is pulled out, and the two sliders 6 move closer together under the action of the elastic member 8, sliding out of the third slot 222 and into the connecting rod 52.

[0061] The design of the slide bar 7 and the insert 71 provides a simple and effective way to control the sliding of the slider 6. By inserting and removing the slide bar 7, the slider 6 can be easily slid in and out, thereby enabling the installation and removal of the locking piece 5. This design improves the convenience and efficiency of operation while ensuring the reliability of the locking piece 5 connection.

[0062] In some examples, the elastic element 8 is disposed at both ends on the two sliders 6 respectively, and the elastic element 8 is used to provide a force for the two sliders 6 to move closer to each other.

[0063] For example, such as Figure 5 As shown, before installing the clip 5, the two ends of the elastic element 8 are respectively connected to the two sliders 6. The elastic element 8 is misaligned with the insertion part 71 to prevent interference between the insertion part 71 and the elastic element 8 when it is inserted. When the insertion part 71 of the slide rod 7 is inserted between the two sliders 6, the elastic element 8 is stretched. When the slide rod 7 is pulled out, the elastic force of the elastic element 8 causes the two sliders 6 to move closer to each other, slide out of the third slot 222 and slide into the connecting rod 52.

[0064] The elastic element 8 enables the slider 6 to automatically reset during sliding. When the clip 5 is removed, the elastic element 8 can automatically pull the slider 6 back into the connecting rod 52.

[0065] In some examples, there are several clips 5, the pump cover 4 also has a second extension 12, and the second sheath body 3 also has a first extension 22. The clips 5 are used to connect the first extension 22 and the second extension 12.

[0066] For example, such as Figure 3 , Figure 6 As shown, the positions of the first extension 22 and the second extension 12 are also confirmed for the pump cover 4 and the second sheath body 3. The second sheath body 3 is placed on the pump cover 4, aligning the first extension 22 and the second extension 12. Then, using several clips 5, the first extension 22 and the second extension 12 are connected by engaging the clips 5 with the first slot 221 and the second slot 121 in the same manner as connecting the pump body 2 and the first sheath body 1.

[0067] The use of multiple clips 5 to connect the pump cover 4 and the second sheath body 3 increases the strength and stability of the connection. Multiple clips 5 can evenly distribute the force, preventing excessive localized stress that could lead to loosening of the connection. This design is suitable for pump bodies 2 and pump covers 4 of different specifications and operating conditions, improving the versatility and reliability of the device.

[0068] In some examples, two second extensions 12 are located between two first extensions 22.

[0069] For example, such as Figure 6 As shown, when installing the pump cover 4 and the second sheath body 3, two second extensions 12 are placed between two first extensions 22 to tightly connect the second sheath body 3 and the pump cover 4. The clamps 5 ensure that there is no gap between the second sheath body 3 and the pump cover 4. Similarly, the first sheath body 1 and the pump body 2 are also ensured to be without gap. Then, the two first extensions 22 are connected and tightened with bolts. The two second extensions 12 are in contact with each other and are squeezed by the two first extensions 22, so that the first sheath body 1 and the second sheath body 3 are securely installed between the pump body 2 and the pump sleeve.
