Description

Technical Field

[0001] This application belongs to the technical field of oil pump assembly, specifically relating to a lifting fixture for assembling an oil pump assembly. Background Technology

[0002] The oil pump is an important component of the engine lubrication system. Its main function is to draw oil from the oil pan, pressurize it, and deliver it to various parts of the engine that require lubrication, such as the crankshaft, connecting rods, camshaft, and valves. This allows the oil to form an oil film at the lubrication points, reducing friction and wear between parts and ensuring the normal operation of the engine.

[0003] For large, multi-cylinder engines, the required oil pump has a high power output, resulting in a large size and weight. Currently, there are generally two methods for assembling oil pumps. One method involves workers carrying the oil pump to the interface between the engine block and the oil pan for assembly, which leads to a heavy workload and worker fatigue, potentially causing safety accidents. The other method uses hoisting equipment for auxiliary lifting. However, when using hoisting equipment, steel cables are needed to secure the oil pump, affecting assembly efficiency. Furthermore, if the steel cables are not securely tied, the oil pump may fall, also potentially causing a safety accident. Utility Model Content

[0004] This application provides a lifting fixture for assembling an oil pump assembly, which reduces the difficulty of assembling the oil pump, reduces the workload of workers, and improves the assembly efficiency and safety of the oil pump.

[0005] The technical solution adopted in this application is as follows:

[0006] A lifting fixture for assembling an oil pump assembly includes a crossbeam, a lifting ring at the top of the crossbeam, and a clamping assembly at the bottom of the crossbeam. The clamping assembly comprises at least two sets, each set including a connector, a first clamping member, a second clamping member, and a connecting member. The first clamping member has a first connecting section, a first clamping section, and a first hinged section between the first connecting section and the first clamping section. The second clamping member has a second connecting section, a second clamping section, and a second hinged section between the second connecting section and the second clamping section. The first hinged section is hinged to the second hinged section. A clamping space for clamping the oil pump assembly is formed between the first clamping section and the second clamping section. The two ends of the connecting member are respectively connected to the first connecting section and the second connecting section, and the connecting member is connected to the connector. The connector is connected to the crossbeam. When the crossbeam rises, the connector applies an upward pulling force to the first connecting section and the second connecting section through the connector, causing the first connecting section and the second connecting section to move towards each other.

[0007] By adopting the above technical solution, when using the lifting fixture of this application to assist in assembling the oil pump assembly, firstly, the lifting ring is attached to the hook of the lifting equipment. Then, the two sets of clamping components are aligned with the required clamping position of the oil pump assembly. Next, a force is applied to the first and second clamping sections to move them away from each other, causing the first and second clamping sections to rotate in a direction away from each other. Simultaneously, the first and second connecting sections rotate relative to each other, and move in a direction away from each other, ultimately opening the clamping space. The first and second clamping sections are then placed on either side of the required clamping position of the oil pump assembly, meaning the required clamping position of the oil pump assembly is located within the clamping space. Then, the hoisting equipment applies an upward pulling force to the hoisting fixture, the lifting ring applies a downward pulling force to the crossbeam, which in turn causes the crossbeam to apply an upward pulling force to the connecting parts. Under the action of the connecting parts, the connecting parts move upward and apply an upward pulling force to the first connecting section and the second connecting section. As a result, the first connecting section and the second connecting section move upward and move towards each other, so that the first clamping section and the second clamping section move towards each other. Finally, the first clamping section and the second clamping section press against the position where the oil pump assembly needs to be clamped and drive the oil pump assembly to move upward, so that the oil pump assembly moves upward to the position where it needs to be assembled. Then, the oil pump assembly is fixed to complete the assembly of the oil pump assembly.

[0008] The lifting fixture described in this application facilitates the assembly of the oil pump assembly, eliminating the need for manual handling by workers during assembly. This reduces workload and improves assembly efficiency, while also minimizing the risk of worker fatigue and accidents, thus enhancing safety during assembly. Furthermore, compared to using steel cables to bind the oil pump assembly, this fixture improves lifting efficiency and assembly efficiency, and increases the stability of the oil pump assembly during lifting, preventing it from falling and causing accidents, further enhancing safety during assembly.

[0009] Optionally, the crossbeam is provided with a plurality of threaded holes at intervals along its length, and the connecting member is fixedly connected to the crossbeam by bolts threaded into the threaded holes.

[0010] By adopting the above technical solution, when the position of the clamping component needs to be adjusted for auxiliary hoisting of different models of oil pump assemblies, the bolts connected to the threaded holes are turned to separate the bolts from the threaded holes. Then the connecting parts are adjusted so that the connecting parts move to the required position. Then the bolts are threaded into the corresponding threaded holes to complete the adjustment of the position of the clamping component.

[0011] Since the connecting parts are fixedly connected to the crossbeam by bolts threaded into threaded holes, and multiple threaded holes are spaced apart along the length of the crossbeam, the relative position of the clamping components and the crossbeam can be adjusted, as can the distance between two adjacent clamping components. This allows the lifting fixture to assist in the lifting of various models of oil pump assemblies, thereby increasing the flexibility of the lifting fixture.

[0012] Optionally, the connector has a slider slidably connected to the crossbeam, the slider being threadedly connected to a locking bolt, the locking bolt having a locking position abutting against the crossbeam and an unlocking position separating from the crossbeam.

[0013] By adopting the above technical solution, when adjusting the position of the clamping component during the auxiliary hoisting of different models of oil pump assemblies, the locking bolt is turned to separate the locking bolt from the crossbeam. Then the slider is slid to make the slider slide relative to the crossbeam, thereby moving the clamping component to the required position. Then the locking bolt is turned in the opposite direction to finally make the locking bolt press against the crossbeam, thus completing the adjustment of the position of the clamping component.

[0014] Because the connecting component has a slider that slides onto the crossbeam, the clamping assembly can be infinitely adjusted along the length of the crossbeam and the distance between two adjacent clamping assemblies. This allows the clamping assembly to assist in the hoisting of various models of oil pump assemblies, increasing the flexibility of the hoisting fixture. Furthermore, the locking bolts can lock the relative position of the slider and the crossbeam to prevent the slider and the crossbeam from sliding relative to each other during the hoisting of the oil pump assembly, thereby increasing the stability of the oil pump assembly during assisted hoisting.

[0015] Optionally, the lifting fixture further includes a lifting beam, which is hinged to the middle of the crossbeam and is perpendicular to the crossbeam. The lifting beam has a strip-shaped hole, and the top wall of the strip-shaped hole is provided with a plurality of limiting grooves that can accommodate the lifting ring. A portion of the lifting ring is located in the strip-shaped hole.

[0016] By adopting the above technical solution, since the top wall of the strip hole is provided with multiple limiting grooves that can accommodate the lifting rings, and the lifting beam is set perpendicular to the crossbeam, the relative position of the lifting rings and the lifting beam can be adjusted by placing the lifting rings in different limiting grooves. The lifting rings can be adjusted according to the center of mass of the oil pump assembly, so that the state of the oil pump assembly can be maintained in the required position when it is hoisted. This avoids the phenomenon that the oil pump assembly still needs to be adjusted by the staff after hoisting. On the one hand, it further reduces the workload of the staff, and on the other hand, it further improves the efficiency of assembling the oil pump assembly.

[0017] Optionally, the connector includes a first segment and a second segment, both of which are hinged to the connector. The end of the first segment away from the connector is hinged to the first connecting segment, and the end of the second segment away from the connector is hinged to the second connecting segment.

[0018] By adopting the above technical solution, when the crossbeam moves upward under the action of the hoisting equipment, the connecting parts move upward with the crossbeam, so that the connecting parts apply an upward pulling force to the first and second sections, and the first and second sections apply an upward pulling force to the first and second clamping members. This causes the first and second connecting sections to move upward under the action of the first and second sections, and at the same time, they move towards each other. Finally, the first and second clamping sections press against the position required to clamp the oil pump assembly, and the oil pump assembly moves upward under the clamping action of the first and second clamping sections, so as to realize that the first and second connecting sections move towards each other under the action of the connecting parts.

[0019] By setting the connector as a first segment and a second segment, the stability of the first clamping member and the second clamping member can be increased on the one hand, and the connection stability between the first clamping member and the second clamping member and the connector can be increased on the other hand.

[0020] Optionally, the connector is a steel wire rope threaded through the connector, with one end of the steel wire rope fixedly connected to the first connecting segment and the other end of the steel wire rope fixedly connected to the second connecting segment.

[0021] By adopting the above technical solution, when the crossbeam moves upward under the action of the hoisting equipment, the connecting parts move upward with the crossbeam, so that the connecting parts apply an upward tension to the wire rope. The two ends of the wire rope apply an upward tension to the first connecting section and the second connecting section respectively, thereby causing the first connecting section and the second connecting section to move upward under the action of the wire rope. At the same time, the two sections move towards each other, so that the first clamping section and the second clamping section are pressed against the position required for clamping the oil pump assembly, and the oil pump assembly moves upward under the clamping action of the first clamping section and the second clamping section, so as to realize that the first connecting section and the second connecting section move towards each other under the action of the connecting parts.

[0022] By using steel wire ropes as connectors, the assembly difficulty of the lifting fixtures can be reduced, thereby reducing the production difficulty of the lifting fixtures. On the other hand, the steel wire ropes are threaded through the connectors, so that the relative positions of the connectors can be automatically adjusted according to the center of mass of the oil pump assembly, thereby increasing the stability of the oil pump assembly during lifting.

[0023] Optionally, the first connecting segment is provided with a locking rod, and the clamping assembly further includes a locking arm. The locking arm has a hinge end that is hinged to the second connecting segment and a locking end opposite to the hinge end. The locking end is provided with a plurality of locking grooves along the length direction of the locking arm that can accommodate the locking rod.

[0024] By adopting the above technical solution, after the first clamping section and the second clamping section are pressed against the required clamping position of the oil pump assembly under the rising action of the crossbeam, the locking arm is rotated, and then the locking arm rotates to the position where the locking rod is located, so that the locking rod is located in the corresponding locking groove, thereby locking the relative rotation of the first clamping component and the second clamping component. This avoids the phenomenon that the oil pump assembly may separate from the first clamping section and the second clamping section when the oil pump assembly is hoisted, thereby increasing the stability of the oil pump assembly when it is assisted in hoisting, and further increasing the safety of assembling the oil pump assembly.

[0025] Optionally, two second clamping members are provided, with the two second clamping members located on opposite sides of the first clamping member.

[0026] By adopting the above technical solution, since there are two second clamping components, and the two second clamping components are respectively located on opposite sides of the first clamping component, the oil pump can be balanced when the clamping assembly clamps the oil pump assembly, so as to avoid the phenomenon that the oil pump assembly will be tilted due to the unbalanced clamping force. This further increases the stability of the oil pump assembly when it is hoisted, thereby further increasing the safety of the oil pump assembly during assembly.

[0027] Optionally, the connector includes a connecting portion and a connecting part rotatably connected to the connecting portion, the connecting portion being connected to the crossbeam, and the connecting part being connected to the connector.

[0028] By adopting the above technical solution, since the connecting part is rotatably connected to the connecting part, and the connecting part is connected to the crossbeam, and the connecting part is connected to the connecting member, the connecting member can rotate relative to the crossbeam, so as to adjust the relative position of the clamping assembly and the crossbeam. This allows the clamping position of the clamping assembly on the oil pump assembly to be adjusted, which on the one hand increases the stability of the oil pump assembly when clamping it, and on the other hand allows the lifting fixture to assist in lifting more models of oil pump assemblies, thereby further increasing the flexibility of the lifting fixture.

[0029] Optionally, the connecting part includes a pull ring and a U-shaped rod passing through the pull ring, the U-shaped rod being connected to the crossbeam, and the pull ring being provided with a rotating rod rotatably connected to the connecting part.

[0030] By adopting the above technical solution, since the U-shaped rod is inserted through the pull ring, the pull ring and the U-shaped rod can swing relative to each other, thereby increasing the adjustment range of the clamping assembly and further improving the flexibility of the lifting fixture; and the pull ring is provided with a rotating rod rotatably connected to the connecting part, thereby ensuring that the connecting part and the connecting part can rotate relative to each other, thus ensuring the adjustment range of the clamping assembly and ensuring the flexibility of the lifting fixture.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0032] 1. The lifting fixture in this application includes a crossbeam, a lifting ring at the top of the crossbeam, and a clamping assembly at the bottom of the crossbeam. At least two sets of clamping assemblies are provided. Each set of clamping assemblies includes a connector, a first clamping member, a second clamping member, and a connecting member. The first clamping member has a first connecting section, a first clamping section, and a first hinged section. The second clamping member has a second connecting section, a second clamping section, and a second hinged section. The first hinged section is hinged to the second hinged section. A clamping space for clamping the oil pump assembly is formed between the first and second clamping sections. The two ends of the connecting member are respectively connected to the first connecting section and the second connecting section, and the connecting member is connected to the connector. The connector is connected to the crossbeam. When the crossbeam rises, the connector applies an upward pulling force to the first and second connecting sections through the connector, causing the first and second connecting sections to move closer to each other. The directional movement facilitates the auxiliary assembly of the oil pump assembly, eliminating the need for manual handling during assembly and reducing workload. This improves assembly efficiency and reduces the risk of fatigue-related accidents, thus enhancing safety. Furthermore, compared to using steel cables to bind the oil pump assembly, this method improves hoisting efficiency and stability, preventing potential falls and accidents, further enhancing overall safety during assembly.

[0033] 2. The crossbeam in this application is provided with multiple threaded holes at intervals along its length. The connecting parts are fixedly connected to the crossbeam through bolts connected to the threaded holes, thereby allowing the relative position of the clamping components and the crossbeam to be adjusted, as well as the distance between two adjacent clamping components to be adjusted. This enables the lifting fixture to assist in the lifting of various models of oil pump assemblies, thereby increasing the flexibility of the lifting fixture.

[0034] 3. The connecting component in this application has a slider that is slidably connected to the crossbeam. The slider is threadedly connected to a locking bolt. The locking bolt has a locking position that abuts against the crossbeam and an unlocking position that is separated from the crossbeam. This allows the clamping assembly to be infinitely adjustable in the length direction of the crossbeam and the distance between two adjacent clamping assemblies to be infinitely adjustable. This enables the clamping assembly to assist in the hoisting of various models of oil pump assemblies, thereby increasing the flexibility of the hoisting fixture. Attached Figure Description

[0048] Reference Figures 1 to 5A lifting fixture for assembling an oil pump is disclosed, comprising a crossbeam 1, a lifting ring 2 at the top of the crossbeam 1, and a clamping assembly 3 at the bottom of the crossbeam 1. At least two sets of clamping assemblies 3 are provided, each set including a connector 31, a first clamping member 32, a second clamping member 33, and a connecting member 34. The first clamping member 32 has a first connecting section, a first clamping section, and a first hinged section located between the first connecting section and the first clamping section. The second clamping member 33 has a second connecting section, a second clamping section, and a connecting member 34 located between the second connecting section and the first clamping section. The first hinge section is hinged to the second hinge section, and a clamping space 321 for clamping the oil pump assembly is formed between the first clamping section and the second clamping section. The two ends of the connector 34 are respectively connected to the first connecting section and the second connecting section, and the connector 34 is connected to the connector 31. The connector 31 is connected to the crossbeam 1. When the crossbeam 1 rises, the connector 31 applies an upward pulling force to the first connecting section and the second connecting section through the connector 34, so that the first connecting section and the second connecting section move toward each other.

[0049] It is understandable that, since the first hinge segment and the second hinge segment are hinged to each other, the first clamping member 32 and the second clamping member 33 together form a scissor structure, so as to clamp the oil pump assembly by using the extrusion force applied by the first clamping segment and the second clamping segment; and, the first clamping segment and the second clamping segment are both bent in the direction of mutual approach to increase the clamping stability of the oil pump assembly.

[0050] When using the lifting fixture described in this application to assist in assembling the oil pump assembly, first, the lifting ring 2 is attached to the hook of the lifting equipment. Then, the two sets of clamping components 3 are aligned with the required clamping positions of the oil pump assembly. Next, a force is applied to the first and second clamping sections to move them away from each other, causing the first and second clamping sections to rotate in a direction away from each other. Simultaneously, the first and second connecting sections rotate relative to each other, and move in a direction away from each other, ultimately opening the clamping space 321. The first and second clamping sections are then placed on either side of the required clamping position of the oil pump assembly, meaning the required clamping position of the oil pump assembly is located within the clamping space 321. Then, the lifting equipment... The hoisting fixture is subjected to an upward pulling force, the lifting ring 2 is subjected to a downward pulling force on the crossbeam 1, and the crossbeam 1 is subjected to an upward pulling force on the connecting piece 31. Under the action of the connecting piece 31, the connecting piece 34 moves upward and applies an upward pulling force to the first connecting section and the second connecting section, so that the first connecting section and the second connecting section move upward and move towards each other, so that the first clamping section and the second clamping section move towards each other, and finally the first clamping section and the second clamping section press against the position where the oil pump assembly needs to be clamped and drive the oil pump assembly to move upward, so that the oil pump assembly moves upward to the position where it needs to be assembled, and then the oil pump assembly is fixed to complete the assembly of the oil pump assembly.

[0051] The lifting fixture described in this application facilitates the assembly of the oil pump assembly, eliminating the need for manual handling by workers during assembly. This reduces workload and improves assembly efficiency, while also minimizing the risk of worker fatigue and accidents, thus enhancing safety during assembly. Furthermore, compared to using steel cables to bind the oil pump assembly, this fixture improves lifting efficiency and assembly efficiency, and increases the stability of the oil pump assembly during lifting, preventing it from falling and causing accidents, further enhancing safety during assembly.

[0052] The better one is to refer to Figures 1 to 3 The clamping assembly 3 is provided in two sets to ensure the stability of clamping the oil pump assembly while reducing the production cost of the lifting tooling.

[0053] Preferably, the crossbeam 1 is made of I-beam to increase the structural strength of the crossbeam 1, thereby increasing the stability of the lifting fixture when assisting in the lifting of the oil pump assembly, and also increasing the service life of the lifting fixture.

[0054] To enable the lifting fixture to assist in the lifting of various models of oil pumps, in a preferred embodiment, refer to... Figure 2 and Figure 3 The relative position of the connecting piece 31 and the crossbeam 1 can be adjusted to adjust the relative position of the clamping assembly 3 and the crossbeam 1, and at the same time, the distance between the two sets of clamping assemblies 3 can be adjusted, so that the lifting fixture can assist in the lifting of different models of oil pump assemblies.

[0055] This application does not specify the method for adjusting the relative position of the connecting member 31 and the crossbeam 1, and it can adopt any one of the following embodiments:

[0056] Example 1, in this example, refers to Figure 2 The crossbeam 1 has multiple threaded holes 11 spaced apart along its length, and the connecting piece 31 is fixedly connected to the crossbeam 1 by bolts threaded to the threaded holes 11.

[0057] It is understandable that the threaded hole 11 is located at the bottom of the crossbeam 1, and the bolt passes through the connector 31 so that the bolt head can fix the connector 31 by applying an upward force to the connector 31.

[0058] When adjusting the position of clamping component 3 for auxiliary hoisting of different models of oil pump assemblies, the bolts threaded to the threaded holes 11 are turned to separate the bolts from the threaded holes 11. Then the connecting piece 31 is adjusted so that it moves to the required position. Then the bolts are threaded into the corresponding threaded holes 11 to complete the adjustment of the position of clamping component 3.

[0059] Since the connecting piece 31 is fixedly connected to the crossbeam 1 by bolts threaded into the threaded hole 11, and multiple threaded holes 11 are spaced apart along the length of the crossbeam 1, the relative position of the clamping assembly 3 and the crossbeam 1 can be adjusted, as can the distance between two adjacent clamping assemblies 3, thereby enabling the lifting fixture to assist in the lifting of various models of oil pump assemblies, thus increasing the flexibility of the lifting fixture.

[0060] Example 2, in this example, refer to Figure 3 The connecting member 31 has a slider 311 that is slidably connected to the crossbeam 1. The slider 311 is threadedly connected to a locking bolt 312. The locking bolt 312 has a locking position that abuts against the crossbeam 1 and an unlocking position that is separated from the crossbeam 1.

[0061] When adjusting the position of the clamping component 3 for auxiliary hoisting of different models of oil pump assemblies, the locking bolt 312 is turned to separate the locking bolt 312 from the crossbeam 1. Then the slider 311 is slid to make the slider 311 slide relative to the crossbeam 1, thereby moving the clamping component 3 to the required position. Then the locking bolt 312 is turned in the opposite direction, and finally the locking bolt 312 is pressed against the crossbeam 1 to complete the adjustment of the position of the clamping component 3.

[0062] Because the connecting part 31 has a slider 311 that is slidably connected to the crossbeam 1, the clamping assembly 3 can be steplessly adjusted in the length direction of the crossbeam 1 and the distance between two adjacent clamping assemblies 3 can be steplessly adjusted. This allows the clamping assembly 3 to assist in the hoisting of various models of oil pump assemblies, thereby increasing the flexibility of the hoisting fixture. Furthermore, the locking bolt 312 can lock the relative position of the slider 311 and the crossbeam 1 to prevent the slider 311 from sliding relative to the crossbeam 1 when hoisting the oil pump assembly, thus increasing the stability of the oil pump assembly when assisting in the hoisting of the oil pump assembly.

[0063] This application does not specifically limit the structure of the slider 311. Preferably, the slider 311 is a block structure sleeved on the outside of the crossbeam 1 to increase the connection stability between the connector 31 and the crossbeam 1. In other embodiments, the crossbeam 1 is provided with a groove along its own length direction, and the slider 311 is a block structure provided inside the groove.

[0064] Of course, in other ways, the connector 31 can also be connected to the crossbeam 1 by welding, riveting or other fixing methods.

[0065] In a preferred embodiment, refer to Figures 1 to 3 The hoisting fixture also includes a lifting beam 4, which is hinged to the middle of the crossbeam 1 and is set perpendicular to the crossbeam 1. The lifting beam 4 has a strip hole 41, and the top wall of the strip hole 41 is provided with multiple limiting grooves 411 that can accommodate the lifting ring 2. Part of the lifting ring 2 is located in the strip hole 41.

[0066] Because the top wall of the slot 41 is provided with multiple limiting grooves 411 that can accommodate the lifting ring 2, and the lifting beam 4 is set perpendicular to the crossbeam 1, the relative position of the lifting ring 2 and the lifting beam 4 can be adjusted by placing the lifting ring 2 in different limiting grooves 411. The lifting ring 2 can be adjusted according to the center of mass of the oil pump assembly, so that the state of the oil pump assembly can be maintained in the required position when the oil pump assembly is hoisted. This avoids the phenomenon that the oil pump assembly still needs to be adjusted by the staff after hoisting. On the one hand, it further reduces the workload of the staff, and on the other hand, it further improves the efficiency of assembling the oil pump assembly.

[0067] Preferably, the lifting ring 2 includes a U-shaped body and a support rod connected to the U-shaped body. The support rod is located in the strip hole 41, and when an upward pulling force is applied to the lifting fixture, the support rod is located in the limiting groove 411.

[0068] This application does not specifically limit the formation method of the limiting groove 411. Preferably, the limiting groove 411 is formed by a groove provided on the top wall of the strip hole 41, so as to reduce the production difficulty of the hoisting tool. In other embodiments, the top wall of the strip hole 41 is provided with a downward protruding rib, and the limiting groove 411 is formed between two adjacent ribs.

[0069] This application does not impose specific limitations on the structure of the connector 34, which can adopt any of the following embodiments:

[0070] Implementation Method 1, in this implementation method, refer to Figure 4 The connector 34 includes a first segment 341 and a second segment 342. Both the first segment 341 and the second segment 342 are hinged to the connector 31. The end of the first segment 341 away from the connector 31 is hinged to the first connecting segment, and the end of the second segment 342 away from the connector 31 is hinged to the second connecting segment.

[0071] It is understandable that one end of the first segment 341 is hinged to the connector 31, and one end of the second segment 342 is hinged to the connector 31. The hinge axis of the first segment 341 and the connector 31 is coaxial with the hinge axis of the second segment 342 and the connector 31. In other words, the first segment 341 and the second segment 342 are hinged to the connector 31 through the same hinge axis.

[0072] When the crossbeam 1 moves upward under the action of the hoisting equipment, the connecting member 31 moves upward along with the crossbeam 1, so that the connecting member 31 applies an upward pulling force to the first section 341 and the second section 342. The first section 341 and the second section 342 apply an upward pulling force to the first clamping member 32 and the second clamping member 33, which in turn causes the first connecting section and the second connecting section to move upward under the action of the first section 341 and the second section 342. At the same time, they move towards each other, so that the first clamping section and the second clamping section are pressed against the position required to clamp the oil pump assembly, and the oil pump assembly moves upward under the clamping action of the first clamping section and the second clamping section, so that the first connecting section and the second connecting section move towards each other under the action of the connecting member 34.

[0073] By configuring the connector 34 to include a first segment 341 and a second segment 342, the stability of the first clamping member 32 and the second clamping member 33 can be increased on the one hand, and the connection stability between the first clamping member 32 and the second clamping member 33 and the connector 34 can be increased on the other hand.

[0074] Implementation Method Two: In this implementation method, refer to... Figure 5 The connector 34 is a steel wire rope that passes through the connector 31. One end of the steel wire rope is fixedly connected to the first connecting section, and the other end of the steel wire rope is fixedly connected to the second connecting section.

[0075] When the crossbeam 1 moves upward under the action of the hoisting equipment, the connecting piece 31 moves upward along with the crossbeam 1, so that the connecting piece 31 applies an upward tension to the wire rope. The two ends of the wire rope apply an upward tension to the first connecting section and the second connecting section respectively, which in turn causes the first connecting section and the second connecting section to move upward under the action of the wire rope. At the same time, the two sections move towards each other, so that the first clamping section and the second clamping section are pressed against the position required for clamping the oil pump assembly, and the oil pump assembly moves upward under the clamping action of the first clamping section and the second clamping section, so that the first connecting section and the second connecting section move towards each other under the action of the connecting piece 34.

[0076] By setting the connector 34 as a steel wire rope, on the one hand, the assembly difficulty of the hoisting tool can be reduced, thereby reducing the production difficulty of the hoisting tool. On the other hand, the steel wire rope is threaded through the connector 31, so that the relative position of the connector 34 and the connector 31 can be automatically adjusted according to the center of mass of the oil pump assembly, thereby increasing the stability of the oil pump assembly when it is hoisted.

[0077] In a preferred embodiment, refer to Figure 1 , Figure 4 and Figure 5 The first connecting section is provided with a locking rod 322, and the clamping assembly 3 also includes a locking arm 331. The locking arm 331 has a hinge end that is hinged to the second connecting section and a locking end opposite to the hinge end. The locking end is provided with a plurality of locking grooves 332 that can accommodate the locking rod 322 along the length direction of the locking arm 331.

[0078] After the first and second clamping sections are pressed against the required clamping positions of the oil pump assembly by the rising action of the crossbeam 1, the locking arm 331 is rotated, thereby causing the locking arm 331 to rotate to the position of the locking rod 322, so that the locking rod 322 is located in the corresponding locking groove 332, thereby locking the relative rotation of the first clamping member 32 and the second clamping member 33. This avoids the phenomenon that the oil pump assembly may separate from the first and second clamping sections when hoisting the oil pump assembly, thereby increasing the stability of the oil pump assembly when assisting in hoisting the oil pump assembly, and further increasing the safety when assembling the oil pump assembly.

[0079] Preferably, the opening of the locking groove 332 faces downward, so as to ensure the engagement stability of the locking rod 322 and the locking groove 332 under the gravity of the locking arm 331.

[0080] This application does not specifically limit the formation of the locking groove 332. Preferably, the side of the locking end is provided with multiple rib structures, and the locking groove 332 is formed between two adjacent rib structures. In other embodiments, the locking groove 332 may also be formed by a notch provided on the side of the locking end.

[0081] In a preferred embodiment, refer to Figure 1 and Figure 4 There are two second clamping components 33, which are located on opposite sides of the first clamping component 32. This allows the oil pump assembly to be balanced when the clamping assembly 3 clamps it, thus preventing the oil pump assembly from tilting due to unbalanced clamping forces. This further increases the stability of the oil pump assembly when it is hoisted, thereby increasing the safety of the oil pump assembly during assembly.

[0082] This application does not specifically limit the structure of the connector 31; preferably, refer to... Figure 3 , Figure 4 and Figure 5 The connector 31 includes a connecting part 313 and a connecting part 314 rotatably connected to the connecting part 313. The connecting part 313 is connected to the crossbeam 1, and the connecting part 314 is connected to the connector 34.

[0083] Since the connecting part 314 is rotatably connected to the connecting part 313, and the connecting part 313 is connected to the crossbeam 1, and the connecting part 314 is connected to the connecting member 34, the connecting member 34 can rotate relative to the crossbeam 1, so as to adjust the relative position of the clamping assembly 3 and the crossbeam 1. This allows the clamping position of the clamping assembly 3 on the oil pump assembly to be adjusted, which on the one hand increases the stability of the oil pump assembly when clamping it, and on the other hand allows the lifting fixture to assist in lifting more models of oil pump assemblies, thereby further increasing the flexibility of the lifting fixture.

[0084] Furthermore, refer to Figure 4 and Figure 5 The connecting part 313 includes a pull ring 316 and a U-shaped rod 315 passing through the pull ring 316. The U-shaped rod 315 is connected to the crossbeam 1. The pull ring 316 is provided with a rotating rod 317 rotatably connected to the connecting part 314.

[0085] Since the U-shaped rod 315 passes through the pull ring 316, the pull ring 316 and the U-shaped rod 315 can swing relative to each other, thereby increasing the adjustment range of the clamping assembly 3 and further improving the flexibility of the lifting fixture; and the pull ring 316 is provided with a rotating rod 317 rotatably connected to the connecting part 314, thereby ensuring that the connecting part 313 and the connecting part 314 can rotate relative to each other, thereby ensuring the adjustment range of the clamping assembly 3 and ensuring the flexibility of the lifting fixture.

[0086] In other embodiments, the connector 31 may also be a block structure connected to the crossbeam 1.
