Description

TECHNICAL FIELD

[0002] In the pump head assembly process, the turnover device is an important equipment to realize the processes of fixing the rotor assembly, sealing installation, pump cover assembly, and impeller installation, etc. The turnover machine in the field usually uses a general clamp to fix the rotor assembly, and then completes the assembly through a manual pressing method, and realizes the turnover operation by means of a hydraulic system. However, the existing turnover machine has many deficiencies in actual application, and needs to be improved to improve the efficiency and safety of pump head assembly. First, the general clamp has the problem of unstable clamping when fixing the rotor assembly, which is prone to slipping and may cause damage to the assembly or injury to the personnel, especially during the turnover process. Second, the manual pressing operation is time-consuming and laborious, which seriously affects the production efficiency. In addition, the existing hydraulic system design is unreasonable, which leads to too fast turnover speed, or serious equipment shaking when starting and stopping the turnover, which not only reduces the stability of the equipment, but also may cause safety hazards to the surrounding environment. These defects make the existing turnover machine difficult to meet the efficient and safe production requirements. Moreover, the existing turnover machine usually relies on external hydraulic lines to provide power, which increases the risk of oil pipe and joint leakage, and the external hydraulic lines also have the risk of entanglement during the rotation of the turnover machine, increasing the frequency of equipment maintenance.

[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0053] Please refer to Figures 1 to 11 The embodiment of the present application provides a turnover device, which comprises a turnover assembly 100 and a clamping assembly 200. The turnover assembly 100 comprises a casing 110, a rotating structure 120 rotatably arranged in the casing 110, and a turnover driving device 130 for driving the rotating structure 120 to rotate. The clamping assembly 200 is arranged outside the casing 110 and comprises a supporting structure 210 connected to the rotating structure 120 and used for placing products, and a pressing structure 220 rotatably arranged on the supporting structure 210 and used for pressing the products on the supporting structure 210.

[0054] Overall, as Figure 1 and Figure 2In the shown embodiment, the overturning device is provided with the overturning assembly 100 and the clamping assembly 200, the rotating structure 120 and the overturning driving device 130 are arranged in the casing 110, and the supporting structure 210 and the pressing structure 220 are arranged outside the casing 110 for clamping the product, so that the rotating structure 120 and the overturning driving device 130 for overturning can be arranged in a centralized manner, and the overall integration of the overturning device is significantly improved.

[0055] Specifically, the casing 110 can provide stable support for the rotating structure 120, the built-in overturning driving device 130 can accurately control the overturning angle of the rotating structure 120, and the overturning is ensured to be in place. Moreover, the clamping assembly 200 is arranged outside the casing 110, which facilitates the quick placement of the product on the supporting structure 210, and through the cooperation of the supporting structure 210 and the pressing structure 220, the stability of the product during the overturning process is ensured, and the risk of accidental falling of the product is reduced.

[0056] The overturning assembly 100 and the clamping assembly 200 are integrated, which effectively reduces the complexity and space occupation caused by the independent arrangement of the components in the existing overturning machine, and makes the overall layout of the overturning device more compact and reasonable, thereby facilitating installation, maintenance and operation.

[0057] The designer can adjust the specific type of product according to the use requirement, which is not specifically limited here. Preferably, the product is a pump device, such as a pump head.

[0058] In the embodiment of the present application, as shown in Figure 2 and Figure 3 The rotating structure 120 includes a main shaft 121 rotatably arranged in the casing 110, the main shaft 121 is connected to the supporting structure 210, and the overturning driving device 130 is used to drive the main shaft 121 to drive the supporting structure 210 to overturn.

[0059] The designer can adjust the installation mode of the main shaft 121 according to the use requirement, which is not specifically limited here. In a feasible embodiment, the main shaft 121 is arranged in a horizontal direction and rotatably mounted in the casing 110 through a bearing assembly.

[0060] Moreover, the overturning driving device 130 can be arranged in the casing 110, so that the overturning driving device 130 and the main shaft 121 can be arranged in a centralized manner, and the integration is improved.

[0061] In the embodiment of the present application, as shown in Figure 6 The designer can adjust the specific structure of the supporting structure 210 according to the use requirement, which is not specifically limited here. Preferably, the supporting structure 210 is made by welding a plate body and a reinforcing rib plate. More preferably, the supporting structure 210 is roughly structured as an L shape.

[0062] In the embodiments of the present application, as shown in the embodiments of Figure 2 and Figure 4 , the overturning driving device 130 comprises an overturning hydraulic cylinder 131, and the rotating structure 120 further comprises a driving handle 122 sleeved on the main shaft 121, and the telescopic rod of the overturning hydraulic cylinder 131 is hinged to the driving handle 122.

[0063] By hinging the overturning hydraulic cylinder 131 to the driving handle 122, the telescopic rod of the overturning hydraulic cylinder 131 drives the main shaft 121 to rotate through the driving handle 122, which realizes efficient transmission and accurate control of force, and significantly improves the stability and reliability of the overturning action.

[0064] In addition, the driving handle 122 with different force arm lengths can be replaced according to the use requirements, so that the overturning requirements in different working conditions can be met without replacing the overturning hydraulic cylinder 131, which has better applicability.

[0065] In the embodiments of the present application, as shown in the embodiments of Figure 2 and Figure 6 , the pressing structure 220 comprises a rotating column 221 arranged on the supporting structure 210, a rotating arm 222 rotatably arranged on the rotating column 221, and a pressing hydraulic cylinder 223 arranged on the rotating arm 222, and the pressing hydraulic cylinder 223 is used to press the product on the supporting structure 210.

[0066] By arranging the rotating column 221 on the supporting structure 210, the rotating column 221 can provide a stable rotating support point for the rotating arm 222, and then the rotating arm 222 can drive the pressing hydraulic cylinder 223 to move above or below the supporting structure 210 to press the product, or the rotating arm 222 can drive the pressing hydraulic cylinder 223 to move to the side of the supporting structure 210 to take or place the product.

[0067] By using the pressing hydraulic cylinder 223, the product can be stably fixed on the supporting structure 210, which improves the stability of the product during the overturning process, especially when facing a large weight pump head, preventing the pump head from falling accidentally, thereby ensuring the operation safety.

[0068] In the embodiments of the present application, as shown in the embodiments of Figure 2 , Figure 3 and Figure 6 , the overturning device further comprises a main shaft oil distributor 140 arranged on the main shaft 121, and a column oil distributor 150 arranged on the rotating column 221.

[0069] As shown in Figure 8 and Figure 9In the shown embodiment, the main shaft oil distributor 140 comprises a first main shaft oil inlet ring cavity 141 and a first main shaft oil outlet ring cavity 142 arranged separately from each other, and the main shaft 121 is provided with a first main shaft oil inlet passage 1211 for connecting the first main shaft oil inlet ring cavity 141 and a first main shaft oil outlet passage 1212 for connecting the first main shaft oil outlet ring cavity 142.

[0070] The column oil distributor 150 comprises a first column oil inlet ring cavity 151 and a first column oil outlet ring cavity 152 arranged separately from each other, and the rotary column 221 is provided with a first column oil inlet passage 2211 for connecting the first column oil inlet ring cavity 151 and a first column oil outlet passage 2212 for connecting the first column oil outlet ring cavity 152, the first column oil inlet passage 2211 is connected with the first main shaft oil inlet passage 1211, and the first column oil outlet passage 2212 is connected with the first main shaft oil outlet passage 1212, the first column oil inlet ring cavity 151 is connected with the oil inlet of the pressing hydraulic cylinder 223, and the first column oil outlet ring cavity 152 is connected with the oil outlet of the pressing hydraulic cylinder 223.

[0071] Further, the rotary column 221 is further provided with a first column oil inlet hole 2213 connected with the first column oil inlet passage 2211 and a first column oil outlet hole 2214 connected with the first column oil outlet passage 2212.

[0072] By arranging the main shaft oil distributor 140 on the main shaft 121 and the column oil distributor 150 on the rotary column 221, the main shaft oil distributor 140 and the column oil distributor 150 can form multiple ring cavities relatively independently, and multiple passages for the hydraulic oil to enter and exit can be arranged in the main shaft 121 and the rotary column 221, i.e., the built-in oil passage structure is formed by the cooperation of the ring cavities and the hydraulic oil passages, so that the hydraulic oil does not need to pass through a relatively long external hydraulic pipeline during the transportation between the main shaft oil distributor 140 and the column oil distributor 150, thereby reducing the number of exposed oil pipes of the oil pipe joint machine, reducing the problem of hydraulic oil leakage caused by oil pipe aging, wear, joint loosening, etc., and improving the working stability of the turnover device.

[0073] Moreover, the built-in oil passage structure significantly reduces the complexity of the arrangement of the external hydraulic pipeline, thereby reducing the maintenance cost. At the same time, since the interference problem caused by the external hydraulic pipeline is eliminated, the turnover device can operate more stably, thereby further improving the safety and service life of the turnover device.

[0074] The designer can adjust the connection mode between the first column oil inlet passage 2211 and the first main shaft oil inlet passage 1211 and between the first column oil outlet passage 2212 and the first main shaft oil outlet passage 1212 according to the use needs, which is not specifically limited herein.

[0075] In a feasible embodiment, as shown in the embodiment of Figure 3 and Figure 8 , the main shaft 121 is provided with a connecting piece 124, and the main shaft 121 is connected with the supporting structure 210 through the connecting piece 124. The connecting piece 124 can be provided as a connecting plate, which is not specifically limited here.

[0076] In addition, the connecting piece 124 is provided with a plurality of relatively independent sub-channels, which are respectively a first sub-channel 1241, a second sub-channel 1242, a third sub-channel 1243, and a fourth sub-channel 1244.

[0077] The first sub-channel 1241 is used to communicate the first column oil inlet hole 2213, and the second sub-channel 1242 is used to communicate the first column oil outlet hole 2214. Through the cooperation of the first sub-channel 1241 and the first column oil inlet hole 2213, the first column oil inlet channel 2211 is connected with the first main shaft oil inlet channel 1211. Through the cooperation of the second sub-channel 1242 and the first column oil outlet hole 2214, the first column oil outlet channel 2212 is connected with the first main shaft oil outlet channel 1212.

[0078] In another feasible embodiment, the main shaft 121 and the clamping assembly 200 are synchronously rotated, the first column oil inlet channel 2211 and the first main shaft oil inlet channel 1211 are communicated through a first transition pipeline, and the first column oil outlet channel 2212 and the first main shaft oil outlet channel 1212 are communicated through a second transition pipeline.

[0079] As known from the foregoing, the turnover assembly 100 can drive the clamping assembly 200 to turn over as a whole, and at this time the column oil distributor 150 and the pressing hydraulic cylinder 223 are synchronously rotated. The designer can adjust the communication mode of the first column oil inlet annular cavity 151 and the oil inlet of the pressing hydraulic cylinder 223, and the communication mode of the first column oil outlet annular cavity 152 and the oil outlet of the pressing hydraulic cylinder 223 according to the use requirement, which is not specifically limited here.

[0080] Preferably, as shown in the embodiment of Figure 2 , the turnover device further comprises a first oil pipe 160 and a second oil pipe 170, the first oil pipe 160 communicates the first column oil inlet annular cavity 151 with the oil inlet of the pressing hydraulic cylinder 223, and the second oil pipe 170 communicates the first column oil outlet annular cavity 152 with the oil outlet of the pressing hydraulic cylinder 223. In addition, the first oil pipe 160 and the second oil pipe 170 are located above the rotary arm 222, so as not to interfere with the product on the supporting structure 210.

[0081] Further, the first column oil distributor 150 is provided with a first column oil distributor oil inlet hole 153 and a first column oil distributor oil outlet hole 154, the first column oil distributor oil inlet hole 153 is used for communicating the first column oil inlet ring cavity 151, and the first column oil distributor oil outlet hole 154 is used for communicating the first column oil outlet ring cavity 152. Moreover, the first column oil distributor oil inlet hole 153 is communicated with one end of the first oil pipe 160, so that the first oil pipe 160 can communicate the first column oil inlet ring cavity 151 with the oil inlet of the pressing hydraulic cylinder 223; and the first column oil distributor oil outlet hole 154 is communicated with one end of the second oil pipe 170, so that the second oil pipe 170 can communicate the first column oil outlet ring cavity 152 with the oil outlet of the pressing hydraulic cylinder 223.

[0082] In the embodiment, the first column oil distributor 150 and the pressing hydraulic cylinder 223 are located at both ends of the rotary arm 222, and the first column oil distributor 150 can rotate synchronously with the rotary arm 222, so that the distance between the first column oil distributor 150 and the pressing hydraulic cylinder 223 is small, and the first oil pipe 160 and the second oil pipe 170 can realize the communication function. After the first oil pipe 160 and the second oil pipe 170 are installed, the first oil pipe 160 and the second oil pipe 170 are in a straight line shape, and do not have the problems of deformation and shaking during the overturning process.

[0083] Moreover, by arranging the first oil pipe 160 and the second oil pipe 170, the communication difficulty between the first column oil distributor 150 and the pressing hydraulic cylinder 223 is reduced, and the stable transmission of the hydraulic oil during the pressing process is ensured. In addition, the first oil pipe 160 and the second oil pipe 170 are independent components, which are convenient to install, disassemble and maintain, and further improve the reliability and maintainability of the overturning device.

[0084] In the embodiment of the present application, as shown in the embodiments of Figure 2 and Figure 7 , the clamping assembly 200 further comprises a rotary driving structure 230 arranged on the supporting structure 210, and the rotary driving structure 230 is used for driving the rotary arm 222 to rotate.

[0085] By arranging the rotary driving structure 230, not only the accurate rotation driving of the rotary arm 222 is realized, but also the angle position of the supporting structure 210 can be locked, so as to avoid the safety risk caused by the accidental falling of the rotary arm 222 and the pressing hydraulic cylinder 223 under the action of gravity during the overturning process, and the problem of accidental rotation of the rotary arm 222 is also avoided, thereby improving the use safety of the overturning device. Moreover, by arranging the rotary driving structure 230, the rotation stroke of the rotary arm 222 can be automatically controlled, and the control accuracy and operation convenience are improved.

[0086] In the embodiment of the present application, as shown in the embodiments of Figure 2 and Figure 7In the illustrated embodiment, the rotary driving structure 230 includes a rotary hydraulic cylinder 231 arranged on the support structure 210, and a transmission structure 232 arranged between the telescopic rod of the rotary hydraulic cylinder 231 and the slewing arm 222.

[0087] Through the cooperation of the rotary hydraulic cylinder 231 and the transmission structure 232, accurate control and efficient driving of the slewing arm 222 are achieved. As a power source, the rotary hydraulic cylinder 231 converts the reciprocating motion of its telescopic rod into the rotary motion of the slewing arm 222 through the transmission structure 232, ensuring the stability and controllability of the slewing process. This not only simplifies the complexity of the transmission system, but also fully utilizes the advantages of hydraulic transmission to provide strong driving force to meet different load requirements.

[0088] Moreover, the cooperation of the rotary hydraulic cylinder 231 and the transmission structure 232 can flexibly adjust the slewing angle of the slewing arm 222, and realize precise positioning combined with the locking function, effectively improving the operation accuracy and use safety of the equipment.

[0089] The designer can adjust the specific structure of the rotary driving structure 230 according to the use needs, which is not specifically limited here. In a feasible embodiment, as shown in Figure 7 In the illustrated embodiment, the transmission structure 232 includes a transmission rack 2321 arranged on the telescopic rod of the rotary hydraulic cylinder 231, and a transmission gear 2322 sleeved on the slewing column 221 and connected to the slewing arm 222.

[0090] Through the cooperation of the transmission rack 2321 and the transmission gear 2322, efficient conversion of the linear motion of the telescopic rod of the rotary hydraulic cylinder 231 to the rotary motion of the slewing arm 222 is achieved, which not only ensures the accuracy and stability of power transmission, but also has high transmission efficiency and load capacity. At the same time, the meshing transmission of the rack and the gear can realize a wide range of angle adjustment to meet the overturning requirements under different working conditions.

[0091] Moreover, through the transmission rack 2321 and the transmission gear 2322, the locking function can be realized, and the angle position of the slewing arm 222 is fixed at a specific operation stage, thereby effectively preventing unintended slewing caused by external interference or gravity, ensuring that the product always maintains the required posture, and reducing the safety risk.

[0092] In the embodiments of the present application, as shown in Figure 10 and Figure 11In the embodiment shown, the spindle oil distributor 140 further includes a second spindle oil inlet ring cavity 143 and a second spindle oil outlet ring cavity 144 that are separated from each other. The spindle 121 is also provided with a second spindle oil inlet channel 1213 for connecting the second spindle oil inlet ring cavity 143 and a second spindle oil outlet channel 1214 for connecting the second spindle oil outlet ring cavity 144. The second spindle oil inlet channel 1213 is connected to the oil inlet of the rotary hydraulic cylinder 231, and the second spindle oil outlet channel 1214 is connected to the oil outlet of the rotary hydraulic cylinder 231.

[0093] Furthermore, the spindle oil distributor 140 is also provided with a first spindle oil distributor inlet 145, a first spindle oil distributor outlet 146, a second spindle oil distributor inlet 147, and a second spindle oil distributor outlet 148. The first spindle oil distributor inlet 145 is connected to the first spindle oil inlet annular cavity 141, the first spindle oil distributor outlet 146 is connected to the first spindle oil outlet annular cavity 142, the second spindle oil distributor inlet 147 is connected to the second spindle oil inlet annular cavity 143, and the second spindle oil distributor outlet 148 is connected to the second spindle oil outlet annular cavity 144.

[0094] By adding a second spindle oil inlet annular cavity 143 and a second spindle oil outlet annular cavity 144, which are separated from each other, and cooperating with the second spindle oil inlet channel 1213 and the second spindle oil outlet channel 1214 inside the spindle 121, precise oil supply and return to the oil inlet and outlet of the rotary hydraulic cylinder 231 are achieved. That is, the annular cavity and the hydraulic oil channel together form an internal oil circuit structure, eliminating the need for long external hydraulic pipelines during the hydraulic oil transport between the spindle oil distributor 140 and the rotary hydraulic cylinder 231. This reduces the number of exposed oil pipes on the pipe joint and lowers the risk of hydraulic oil leakage due to pipe aging, wear, loose joints, etc.

[0095] Furthermore, the built-in hydraulic circuit structure significantly reduces the complexity of external hydraulic piping layout, lowering maintenance costs. Simultaneously, eliminating potential interference issues from external hydraulic piping allows the tilting device to operate more stably, further enhancing its safety and lifespan.

[0096] Designers can adjust the connection between the oil inlet of the second spindle oil inlet channel 1213 and the oil inlet of the rotary hydraulic cylinder 231, and between the oil outlet of the second spindle oil outlet channel 1214 and the oil outlet of the rotary hydraulic cylinder 231, according to the needs of use. No specific restrictions are imposed here.

[0097] In an embodiment, the second main shaft oil inlet channel 1213 is communicated with the third sub-channel 1243 of the connecting piece 124 and communicated with the oil inlet of the rotary hydraulic cylinder 231 through a third transition pipeline, and the second main shaft oil outlet channel 1214 is communicated with the fourth sub-channel 1244 of the connecting piece 124 and communicated with the oil outlet of the rotary hydraulic cylinder 231 through a fourth transition pipeline.

[0098] In an embodiment of the present application, as shown in the embodiment, Figure 5 the turnover assembly 100 further comprises a brake device 180, and the rotating structure 120 further comprises a brake disc 123 sleeved on the main shaft 121, and the brake device 180 is capable of locking the main shaft 121 through the brake disc 123.

[0099] The reliable locking of the rotating position of the main shaft 121 is achieved through the brake device 180, which can better meet the locking needs of large weight. When the equipment needs to be kept stationary at a specific angle, the brake device 180 can effectively inhibit the unintended rotation of the main shaft 121 due to external force or inertia through cooperation with the brake disc 123, thereby ensuring that the products on the supporting structure 210 always maintain a stable posture during assembly or detection, thereby improving the operation precision and safety. At the same time, the brake device 180 simplifies the locking process, reduces the dependence on other mechanical components, and further improves the reliability and maintenance convenience of the system.

[0100] The specific structure of the brake device 180 can be adjusted by the designer according to the needs, which is not limited here. In an embodiment, the brake device 180 comprises a brake bracket 181, two brake levers 182 hingedly connected to the brake bracket 181 and oppositely arranged, two brake pads 183 arranged on the two brake levers 182 respectively, and a brake hydraulic cylinder 184 for driving the two brake levers 182 to approach or separate.

[0101] The brake bracket 181 is fixedly arranged in the cabinet 110 to serve as a support, and the two brake levers 182 are hingedly connected to the brake bracket 181, so that the two brake levers 182 can drive the brake pads 183 to clamp the brake disc 123, thereby achieving better braking effect.

[0102] In an embodiment of the present application, as shown in the embodiment, Figure 12 the hydraulic control system is connected in parallel with the turnover hydraulic cylinder 131, the rotary hydraulic cylinder 231, the pressing hydraulic cylinder 223 and the brake hydraulic cylinder 184, so as to achieve independent control and have better use effect.

[0103] The specific structure and control mode of the hydraulic control system can be adjusted by the designer according to the needs, which is not limited here. For example, the hydraulic control system can be controlled by a PLC module.

[0104] In the embodiments of the present application, as shown in the embodiments, Figure 2 the turnover device further comprises a clamp assembly 190, which comprises a first clamp seat 191 arranged on the supporting structure 210 and a second clamp seat 192 arranged on the telescopic rod of the pressing hydraulic cylinder 223.

[0105] By arranging the first clamp seat 191 on the supporting structure 210 and the second clamp seat 192 on the telescopic rod of the pressing hydraulic cylinder 223, the first clamp seat 191 can more stably support the product, such as the pump head, and can lift the pump head by a preset height, thereby facilitating the subsequent installation operation. The second clamp seat 192 can perform telescopic movement with the telescopic rod of the pressing hydraulic cylinder 223, and the second clamp seat 192 can better abut against the outer wall of the pump head, thereby improving the stability of pressing.

[0106] The designer can adjust the specific structure of the first clamp seat 191 and the second clamp seat 192 according to the use requirement, which is not specifically limited here. For example, the first clamp seat 191 comprises an adjusting pad arranged on the supporting structure 210, and the adjusting pad can be detachably arranged, so that different heights of adjusting pads can be replaced according to the use requirement, thereby having better use flexibility. The second clamp seat 192 comprises a pressing block arranged on the telescopic rod of the pressing hydraulic cylinder 223, and the pressing block has a larger area, so that the pressing block can be more stably pressed against the outer wall of the pump head, thereby improving the pressing effect.

[0107] By cooperation of the first clamp seat 191 and the second clamp seat 192, the processing error caused by loosening or displacement of the pump head can be effectively avoided, and the clamp assembly 200 can better adapt to the requirements of pump heads of different sizes and shapes, thereby improving the universality and operation efficiency of the clamp assembly 200 and providing a powerful guarantee for high-quality production.
