Description

Technical Field

[0001] This utility model relates to the field of disassembly auxiliary tools, and in particular to a screw disassembly machine for a twin-screw pump. Background Technology

[0002] As a core component of screw air compressors, twin-screw pumps play a crucial role in industrial production. The compressed air generated by screw air compressors provides vital power support for the pneumatic systems of waste treatment equipment and soot blowing systems, and their stable operation is directly related to the efficient implementation of waste treatment and related tasks.

[0003] During the long-term operation of screw air compressors, twin-screw pumps inevitably encounter various malfunctions. When the equipment exhibits abnormal noise, insufficient output, excessive vibration, jamming, or other issues, or after prolonged use, disassembly, inspection, and repair are necessary to ensure the equipment's normal performance. During repair, the disassembled screws (i.e., male and female rotors) require a series of processes, including surface smoothing and cleaning, bearing replacement, seal replacement, and clearance adjustment, to ensure the twin-screw pump can be restored to good working condition.

[0004] However, current methods for disassembling the screws of twin-screw pumps are relatively traditional and cumbersome. (See...) Figure 5 and Figure 6 As shown, because the twin-screw pump 7 has two screws 72 rotatably connected to the bearing 71, disassembly often requires the coordinated operation of multiple workers. Typically, the twin-screw pump is placed on a work stand, with one worker manually tapping the screws to disengage them from the bearing 71, while one or two other workers below catch the screws after they have been knocked off the bearing 71. This disassembly method is not only labor-intensive, but the force and angle of manual tapping are also difficult to control precisely, easily causing unnecessary damage to the screws, bearings, and other components. Furthermore, there are certain safety hazards for the workers below while catching the screws, affecting disassembly efficiency and repair quality.

[0005] While some screw extrusion devices exist in the existing technology, these devices can only operate on single-screw pumps and cannot meet the disassembly requirements of twin-screw pumps. When dealing with twin-screw pumps, using existing single-screw extrusion devices is extremely cumbersome due to the weight of the pump, making it difficult to manually move the pump to adjust the alignment of the device with the two screws. This not only fails to improve disassembly efficiency but may also damage the screws due to misalignment. Furthermore, these existing devices do not solve the problem of requiring workers to support the screws below during disassembly, posing a safety hazard. Therefore, there is an urgent need for a screw disassembly machine that can adapt to twin-screw pumps, achieve rapid disassembly, and ensure operational safety.

[0006] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a screw disassembly machine for a twin-screw pump, which is designed to facilitate the disassembly of the two screws of the twin-screw pump and to receive the disassembled screws without damage.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A screw disassembly machine for a twin-screw pump includes a worktable, a stand mounted on the worktable, a stamping mechanism mounted on top of the stand, and a screw receiving carriage mounted below the worktable. The stamping mechanism is located above the worktable and is used to stamp the screw of the twin-screw pump to disengage it from the bearing. The worktable is provided with a sliding plate that can move in a front-back direction and an adjusting mechanism for driving the sliding plate. The sliding plate is provided with a contoured positioning rim for positioning the twin-screw pump and has a first discharge port located within the contoured positioning rim. The worktable has a second discharge port corresponding to the position of the first discharge port. The receiving chamber of the screw receiving carriage is provided with a buffer airbag.

[0010] As a further improvement to the above technical solution, the adjustment mechanism includes a rack disposed on one side of the slide plate, a rotating shaft vertically rotatably disposed on the worktable, a gear sleeved on the rotating shaft and meshing with the rack for transmission, and a rotation driver connected to the rotating shaft for driving.

[0011] As a further improvement to the above technical solution, the rotary drive is a handwheel.

[0012] As a further improvement to the above technical solution, the rotary driver is a servo motor, the worktable is provided with a first position detection photoelectric sensor, a second position detection photoelectric sensor and a third position detection photoelectric sensor, the top surface of the rack is provided with a contact piece, when the contact piece triggers the first position detection photoelectric sensor, the slide plate is located at the initial working position, when the contact piece triggers the second position detection photoelectric sensor, the slide plate is located at the first screw disassembly working position, when the contact piece triggers the third position detection photoelectric sensor, the slide plate is located at the second screw disassembly working position.

[0013] As a further improvement to the above technical solution, the workbench is provided with a track to guide the sliding plate to move back and forth.

[0014] As a further improvement to the above technical solution, the slide plate and the worktable are lubricated by grease, and the gear and rack are lubricated by grease.

[0015] As a further improvement to the above technical solution, the stamping mechanism includes a mounting base disposed on the top of the stand, a linear driver disposed vertically on the top of the mounting base, a stamping rod connected to the output end of the linear driver, and a punching and disassembling head disposed at the bottom end of the stamping rod.

[0016] As a further improvement to the above technical solution, the bottom of the mounting base is provided with a guide sleeve for guiding the vertical movement of the stamping rod.

[0017] As a further improvement to the above technical solution, the screw receiving vehicle includes a box with an upper opening, a handle on the box, a base plate below the box, and casters at the bottom of the base plate. Upper positioning cylinders are provided at the bottom corners of the box, and lower positioning cylinders, which are the same number as the upper positioning cylinders and correspond one-to-one, are provided on the base plate. A buffer spring is provided between the upper and lower positioning cylinders. The buffer airbag is provided on the inner wall of the box.

[0018] As a further improvement to the above technical solution, the back of the buffer airbag is provided with a strap, and the side wall of the box is provided with a strap groove for the strap to pass through.

[0019] Beneficial effects: The screw disassembly machine for the twin-screw pump provided by this utility model has the following advantages: 1. The sliding plate driven by the adjustment mechanism moves the twin-screw pump, eliminating the need for manual labor to move the heavy twin-screw pump. This allows for quick and accurate alignment of the two screws with the stamping mechanism, significantly shortening the alignment and disassembly time and effectively improving overall work efficiency.

[0020] 2. The use of a stamping mechanism to replace manual hammering ensures controllable pressure, preventing damage to components such as screws and bearings caused by improper manual hammering force and angle. The screw receiving cart under the workbench automatically catches falling screws, eliminating the need for manual catching by operators and ensuring their safety. Furthermore, the buffer airbags in the receiving chamber of the screw receiving cart effectively cushion the falling screws. The method of disassembling and promptly moving screws to the next workstation avoids rigid collisions between two screws, further preventing damage to the screw surface and ensuring the integrity of the components, which is beneficial for subsequent maintenance and reuse.

[0021] 3. The contour positioning edge on the slide plate can achieve precise pre-positioning according to the shape of the twin screw pump. On the one hand, it ensures that the movement path of the twin screw is directly below the stamping mechanism, which is convenient for alignment. On the other hand, it ensures that the twin screw pump will not be displaced during the stamping process, which improves the stability and reliability of the disassembly process and reduces operational errors caused by inaccurate positioning.

Detailed Implementation

[0029] This utility model provides a screw disassembly machine for a twin-screw pump. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, 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, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0031] Please see Figures 1 to 4 As shown, this utility model provides a screw disassembly machine for a twin-screw pump, including a workbench 11, a stand 12 mounted on the workbench 11, a stamping mechanism 2 mounted on the top of the stand 12, and a screw receiving carriage 3 mounted below the workbench 11. The stamping mechanism 2 is located above the workbench 11 and is used to stamp the screw 72 of the twin-screw pump 7, causing the screw 72 to disengage from the bearing 71. The workbench 11 is provided with a sliding plate 4 that can move in the front-back direction and an adjusting mechanism 5 for driving the sliding plate 4 to move. The sliding plate 4 is provided with a contoured positioning rim 41 for positioning the twin-screw pump 7 and has a first discharge port 42 located within the contoured positioning rim 41. The workbench 11 has a second discharge port 110 corresponding to the position of the first discharge port 42. The receiving chamber of the screw receiving carriage 3 is provided with a buffer airbag 31.

[0032] During operation, the slide plate 4 is in the initial position, located behind the stamping mechanism 2. First, the twin-screw pump 7 to be disassembled is placed inside the contour positioning edge 41 of the slide plate 4. The contour positioning edge 41 is used to achieve accurate initial positioning of the twin-screw pump 7. The slide plate 4 above the worktable 11 is driven to move forward by the adjustment mechanism 5. After being adjusted to a suitable position, it is ensured that one of the screws 72 of the twin-screw pump 7 corresponds to the position of the stamping mechanism 2 and the second material discharge port 110.

[0033] After positioning, the stamping mechanism 2 located above the worktable 11 is activated to stamp the first screw 72, applying appropriate pressure to disengage the screw 72 from the bearing 71. Under the influence of gravity, the screw 72, disengaged from the bearing 71, falls sequentially through the first discharge port 42 on the slide plate 4 and the second discharge port 110 on the worktable 11, finally landing in the receiving chamber of the screw receiving carriage 3 located below the worktable 11. The buffer airbag 31 in the receiving chamber cushions the falling screw 72, preventing it from being damaged by impact.

[0034] After the first screw 72 is pressed out, the worker can push the screw receiving cart 3 to the next maintenance station, remove the first screw 72 from the screw receiving cart 3, and then reset the screw receiving cart 3. Subsequently, the adjusting mechanism 5 drives the slide plate 4 to move to a suitable position so that the stamping mechanism 2 can be aligned with the second screw 72. The stamping mechanism 2 starts again to stamp the second screw 72, causing it to disengage from the bearing 71. The disengaged second screw 72 then falls into the reset screw receiving cart 3 through the first discharge port 42 and the second discharge port 110 in sequence. This completes the disassembly of the two screws 72 one by one, avoiding rigid collision between the two screws 72 and causing damage.

[0035] Compared with the prior art, the screw disassembly machine of the twin screw pump 7 provided by this utility model has the following advantages: 1. The sliding plate 4 is driven by the adjustment mechanism 5 to move the twin screw pump 7. The heavy twin screw pump 7 can be moved quickly without manual effort, and the two screws 72 and the stamping mechanism 2 can be accurately aligned, which greatly shortens the alignment and disassembly time and effectively improves the overall work efficiency.

[0036] 2. The use of a stamping mechanism 2 to replace manual hammering, with controllable pressure, avoids damage to components such as the screw 72 and bearing 71 caused by improper manual hammering force and angle. The screw receiving carriage 3 under the workbench 11 can automatically receive the falling screw 72, eliminating the need for manual receiving by personnel below, thus eliminating safety hazards and effectively ensuring the personal safety of operators. In addition, the buffer airbag 31 in the receiving chamber of the screw receiving carriage 3 can effectively buffer the falling screw 72. The method of disassembling and moving the screw 72 one by one to the next work station in a timely manner avoids rigid collision between two screws 72, further preventing the surface of the screw 72 from being damaged by impact, ensuring the integrity of the components, and facilitating subsequent maintenance and reuse.

[0037] 3. The contour positioning edge 41 on the slide plate 4 can achieve precise pre-positioning according to the shape of the twin screw pump 7. On the one hand, it ensures that the moving path of the twin screw 72 is located directly below the stamping mechanism 2, which is convenient for alignment. On the other hand, it ensures that the twin screw pump 7 will not be displaced during the stamping process, which improves the stability and reliability of the disassembly process and reduces operational errors caused by inaccurate positioning.

[0038] Specifically, the adjustment mechanism 5 includes a rack 51 mounted on one side of the slide plate 4, a rotating shaft 52 vertically rotatably mounted on the worktable 11, a gear 53 sleeved on the rotating shaft 52 and meshing with the rack 51, and a rotary driver connected to the rotating shaft 52. The bottom surface of the worktable 11 is provided with a bearing seat rotatably connected to the rotating shaft 52. The meshing transmission between the gear 53 and the rack 51 has high transmission accuracy and stability. The rotary driver drives the rotating shaft 52 to rotate the gear 53, thereby moving the rack 51 and the slide plate 4, enabling fine-tuning of the position of the twin-screw pump 7. Compared to traditional manual adjustment or other coarse adjustment methods, this method can precisely control the movement distance of the slide plate 4, ensuring high-precision alignment of the screw 72 of the twin-screw pump 7 with the stamping mechanism 2, effectively avoiding damage to the screw 72 due to alignment deviations, and further ensuring disassembly quality.

[0039] In the first embodiment, the rotary actuator is a handwheel 54. The handwheel 54 is operated manually by the operator, allowing for flexible adjustment of the rotation speed and amount according to actual needs, thus achieving precise control over the movement of the slide plate 4. During the alignment process of the twin-screw pump 7, the operator can observe and perceive the real-time movement of the slide plate 4, making timely fine adjustments to ensure the alignment accuracy of the screw 72 and the stamping mechanism 2.

[0040] In another embodiment, the rotary driver is a servo motor, the worktable 11 is equipped with a first position detection photoelectric sensor, a second position detection photoelectric sensor, and a third position detection photoelectric sensor, and the top surface of the rack 51 is equipped with a contact plate. The servo motor has high-precision speed and position control capabilities, and in conjunction with the linkage between the position detection photoelectric sensor and the contact plate, it can realize the automatic switching of the slide plate 4 between the initial station, the first screw 72 disassembly station, and the second screw 72 disassembly station.

[0041] When the contact plate triggers the first position detection photoelectric sensor, the slide plate 4 is in the initial position. When the contact plate triggers the second position detection photoelectric sensor, the slide plate 4 is in the disassembly position of the first screw 72. When the contact plate triggers the third position detection photoelectric sensor, the slide plate 4 is in the disassembly position of the second screw 72. No manual adjustment by operators is required; the servo motor can quickly drive the slide plate 4 to move and accurately position itself according to a preset program or position detection signal. This reduces the time required for manual intervention, speeds up the switching speed of disassembling the two screws 72, and thus improves the overall disassembly efficiency of the twin-screw pump 7.

[0042] The workbench 11 is equipped with a controller and control switches to facilitate the operation of the stamping mechanism 2 and the adjustment mechanism 5 by the operator.

[0043] Furthermore, the workbench 11 is provided with a track 6 for guiding the slide plate 4 to move back and forth. The track 6 can ensure that the slide plate 4 always slides smoothly in a preset direction, effectively limiting the lateral deviation or swaying of the slide plate 4 during the movement process, and avoiding the misalignment between the screw 72 and the stamping mechanism 2 caused by the deviation of the slide plate 4.

[0044] To ensure smooth movement of the slide plate 4, grease is used to lubricate both the slide plate 4 and the worktable 11, as well as the gear 53 and rack 51. The grease forms a lubricating film between the contact surfaces, effectively reducing the coefficient of friction between the slide plate 4 and the worktable 11, and between the gear 53 and rack 51, thus reducing frictional resistance during relative movement. This makes the movement of the slide plate 4 on the track 6 smoother, and the meshing transmission of the gear 53 and rack 51 requires less effort. Whether manually operated by the handwheel 54 or driven by a servo motor, the driving force requirement is reduced, and energy consumption is decreased.

[0045] Specifically, the stamping mechanism 2 includes a mounting base 21 on top of the stand 12, a linear actuator 22 vertically positioned on top of the mounting base 21, a stamping rod 23 connected to the output end of the linear actuator 22, and a punching / removing head 24 located at the bottom of the stamping rod 23. The linear actuator 22 (such as a hydraulic cylinder, pneumatic cylinder, or electric push rod) provides a stable and adjustable driving force, which can flexibly adjust the stamping pressure according to the tightness of the fit between the screw 72 and the bearing 71, avoiding damage to the screw 72 due to excessive force or failure to disengage due to insufficient force, thus achieving precise control of the stamping process.

[0046] The punching head 24 is made of rubber with a certain degree of elasticity and hardness. When it comes into contact with the screw 72, it can transmit sufficient punching force and buffer the impact force through its own deformation. This prevents the metal punching parts from directly contacting the surface of the screw 72 and causing scratches, indentations and other damage. In particular, it can protect the smoothness of the screw 72 surface and provide a good foundation for subsequent inspection, cleaning and maintenance.

[0047] Furthermore, the bottom of the mounting base 21 is provided with a guide sleeve 25 for guiding the vertical movement of the stamping rod 23. The guide sleeve 25 can accurately guide the vertical movement of the stamping rod 23, effectively limiting the lateral deviation or swaying of the stamping rod 23 during movement. This ensures that the punching head 24 at the bottom of the stamping rod 23 can always be accurately aligned with the central axis of the screw 72, ensuring that the punching force is applied to the screw 72 entirely in the vertical direction, avoiding uneven force distribution caused by the misalignment of the stamping rod 23, and further improving the smoothness and accuracy of the screw 72 disengaging from the bearing 71.

[0048] Specifically, the screw receiving vehicle 3 includes a housing 32 with an upper opening, a handle 33 mounted on the housing 32, a base plate 34 located below the housing 32, and casters 35 mounted on the bottom of the base plate 34. Upper positioning cylinders 36 are provided at each of the bottom corners of the housing 32. The base plate 34 has lower positioning cylinders 37, the same number as the upper positioning cylinders 36, which correspond one-to-one. A buffer spring 38 is provided between the upper positioning cylinders 36 and the lower positioning cylinders 37. A buffer airbag 31 is mounted on the inner wall of the housing 32. The buffer spring 38 provides primary buffering when the screw 72 falls into the housing 32, effectively mitigating the impact force of the falling screw 72. Simultaneously, the buffer airbag 31 on the inner wall of the housing 32 forms secondary buffering, directly absorbing the collision force when the screw 72 contacts the housing wall. The dual buffer structure minimizes vibration and impact on the screw 72 during the receiving process, especially protecting the smoothness of the screw 72 surface and preventing damage such as dents and scratches, thus providing a good foundation for subsequent maintenance.

[0049] The casters 35 at the bottom of the base plate 34 allow the screw receiving cart 3 to be easily pushed, while the handle 33 on the housing 32 provides a convenient grip for workers to push and pull the screw receiving cart 3. After the first screw 72 is lowered in, workers can easily push the screw receiving cart 3 to the next maintenance station using the handle 33, remove the screw 72, and then reset it to receive the second screw 72. This eliminates the need to laboriously carry the heavy screw 72, significantly reducing the intensity of manual operation and speeding up the transfer of the two screws 72 after disassembly, thus improving overall work efficiency.

[0050] To better secure the airbag 31, a strap 39 is provided on the back of the airbag 31, and a slot 321 for the strap 39 to pass through is provided on the side wall of the housing 32. After the strap 39 passes through the slot 321, it can tightly fix the airbag 31 to the inner wall of the housing 32, effectively preventing the airbag 31 from shifting, falling off, or wrinkling due to impact when the screw 72 falls in. This fixing method ensures that the airbag 31 is always in the preset buffer position, ensuring that it fully exerts its buffering effect when in contact with the screw 72, avoiding buffering failure caused by the displacement of the airbag 31, and further protecting the screw 72 from damage.

[0051] During long-term use, the airbag 31 may experience a decrease in air pressure due to frequent impacts from the screw 72 or natural leakage, resulting in a decline in its cushioning performance. The air nozzle allows operators to replenish the airbag 31 with air at any time using an inflation device, ensuring that the air pressure inside the airbag 31 remains within a suitable range. This guarantees stable elasticity and cushioning capacity, continuously and effectively absorbing the impact force of the screw 72 during its descent, and preventing damage to the screw 72 due to insufficient air pressure in the airbag 31.

[0052] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
