Description

Technical Field

[0001] The present invention relates to the technical field of generator set assembly, and more particularly to an open-frame generator set assembly system. Background Art

[0002] A generator set is a complete set of mechanical devices that converts other forms of energy into electrical energy. Its core components include the engine that provides power, the generator that realizes energy conversion, the control system that ensures the stable operation of the unit, and the chassis that plays a bearing and fixing role. Some units are also equipped with auxiliary components such as fuel tanks and radiators. The assembly of the generator set is a process of precisely integrating the core and auxiliary components according to the design requirements. The chassis serves as the bearing foundation of the unit and often needs to be in rigid contact with the mounting surface. The engine serves as a power source and will generate periodic mechanical vibrations due to the reciprocating motion of the piston, the rotation of the crankshaft, etc. when working. The vibration will be directly transmitted to the chassis through a rigid connection. Therefore, in the existing method, a shock-absorbing mechanism is usually installed between the chassis and the unit. The shock-absorbing mechanism absorbs vibration energy through elastic elements, which can effectively reduce the vibration transmission efficiency between the unit and the chassis, and between the chassis and the mounting base.

[0003] At present, the assembly of generator sets mostly relies on manual labor or semi-automatic equipment. The specific process is: first, the shock absorber mechanism is installed on the base frame with bolts, and then the unit is moved to the top of the base frame with the help of a lifting mechanism. Then, the unit is controlled to descend and docked with the shock absorber mechanism on the base frame for installation.

[0004] However, the chassis is typically a rectangular frame constructed of section steel (such as channel steel). To ensure top surface flatness, the section steel notches must face downward, and the shock absorber is bolted to the top of the section steel. Therefore, workers must reach into the notches to operate, and even use tools to tighten them. However, some areas are narrow, making access difficult. This not only complicates the process but can also lead to injury. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide an open-frame generator set assembly system.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an open-frame generator set assembly system, comprising a hoisting component, a unit mechanism arranged inside the hoisting component, a balancing component, a scissors-type lifting platform, and a base frame mechanism, wherein the unit mechanism is hoisted and connected to the hoisting component, the scissors-type lifting platform is located above the balancing component, and the base frame mechanism is arranged above the scissors-type lifting platform.

[0007] The chassis mechanism includes two first channel steels arranged on the top of the scissor lift platform, two second channel steels are connected between the two first channel steels, and two shock absorbing mechanisms are arranged on the top of each of the second channel steels.

[0008] Each of the shock-absorbing mechanisms includes a shock-absorbing seat arranged on the top of the corresponding second channel steel and two second bolts inserted into the shock-absorbing seat. The bottoms of the two second bolts pass through the corresponding second channel steel and are threadedly connected to a rod body. A through hole is opened on the outer wall of each rod body, and an extrusion rod is passed through the inside of the through hole.

[0009] The present invention is further configured as follows: a positioning plate is connected to the outer wall of one end of the extrusion rod, a screw is connected to the end of the positioning plate away from the extrusion rod, a nut is threadedly connected to the outer wall of the screw, a rectangular groove is provided on the side wall of the first channel steel away from the second channel steel and at a position corresponding to the positioning plate, the positioning plate is adapted to the corresponding rectangular groove, and positioning grooves are provided on the top and bottom surfaces of the rectangular groove close to the second channel steel.

[0010] A horizontal portion is provided at the bottom of the inner wall of the through hole, the cross-section of the extrusion rod is cam-shaped, two fixing plates are connected to the middle position of the bottom of the second channel steel, a through hole is provided on the side wall of the fixing plate, and one end of the extrusion rod is inserted into the corresponding through hole.

[0011] The present invention is further configured as follows: the lifting assembly includes a frame, two sets of slide rails are provided on the top of the frame, the tops of the two sets of slide rails are slidably connected to transfer trolleys, electric winches are installed on the tops of the two transfer trolleys, and a chain lifting mechanism is hoisted at the bottom of the electric winch, and the bottom of the chain lifting mechanism cooperates with the unit mechanism for lifting.

[0012] The present invention is further configured as follows: the unit mechanism includes a unit body and a first leg and a second leg connected to the bottom of the unit body, a plurality of lifting rings are connected to the top of the unit body, and the plurality of lifting rings are all socketed with the chain lifting mechanism, the first leg and the second leg correspond to the two second channel steels, and the first leg and the second leg are respectively fitted with the tops of the two shock-absorbing mechanisms above the corresponding second channel steels, and the tops of the first leg and the second leg are each provided with two connecting holes, the two connecting holes are arranged corresponding to the corresponding two shock-absorbing mechanisms, and a first bolt is arranged above each of the connecting holes, and the bottom end of the first bolt passes through the connecting hole and is threadedly connected to the corresponding shock-absorbing seat.

[0013] By adopting the above technical solution, the shock absorber seat is connected by plugging and matching the extrusion rod with the rod body, the positioning plate with the positioning groove, and utilizing the plug-in locking method of the mechanical structure. There is no need to rely on bolts for fixation, which eliminates the tedious operation of screwing bolts in a narrow space and avoids the safety hazard of hand insertion. The extrusion rod is rotated to squeeze the convex tip of the outer wall of the extrusion rod against the horizontal part of the through hole, driving the rod body to tighten downward to achieve the tightening and positioning of the shock absorber seat. The positioning plate is inserted into the positioning groove and locked by a nut on one side of the first channel steel. This not only overcomes the hand operation in the narrow groove, but also ensures that the shock absorber seat is stable and shake-free through the coordinated locking of the mechanical structure, thereby improving operational safety.

[0014] The present invention is further configured as follows: the balancing assembly includes a track and two movable carts slidably connected to the top of the track, an auxiliary mechanism is installed on the top of each movable cart, the unit mechanism is located between the two groups of the auxiliary mechanisms, and two groups of supporting mechanisms are provided on the opposite sides of the two auxiliary mechanisms, and the supporting mechanism is arranged toward the unit mechanism.

[0015] The present invention is further configured as follows: each group of the auxiliary mechanisms includes a base installed on the top of the corresponding mobile trolley and two upright frames symmetrically installed on the top of the base, the same side of the two upright frames is connected to a guide rail, and the same side of the two guide rails is slidably connected to a lifting plate.

[0016] The present invention is further configured as follows: two lifting cylinders are installed on the top of the base, the piston rod ends of the two lifting cylinders are connected to a connecting plate, one side of the connecting plate is connected to the lifting plate, and two groups of supporting mechanisms corresponding to a group of auxiliary mechanisms are symmetrically arranged on the side wall of the lifting plate facing the unit mechanism.

[0017] The present invention is further configured as follows: each group of the supporting mechanisms includes an L-shaped supporting plate arranged on the side wall of the corresponding lifting plate, and a rubber pad is installed on the top supporting surface of the L-shaped supporting plate.

[0018] The present invention is further configured as follows: a U-shaped frame is installed on the side wall of the lifting plate, one side of the two L-shaped support plates are inserted between the U-shaped frame and the lifting plate, one side of the L-shaped support plate is connected to a U-shaped block, the U-shaped block is sleeved on the outer wall of the U-shaped frame, a threaded hole is opened on one side of the U-shaped block, and the internal thread of the threaded hole is connected to a locking bolt.

[0019] By adopting the above technical solution, two sets of L-shaped support plates and rubber pads of the supporting mechanism are used to flexibly support the bottom of the unit body, which can stably control the posture of the unit mechanism during the lifting process, prevent the impact pressure generated when the first leg, the second leg and the shock-absorbing mechanism are aligned due to shaking, and reduce the tearing or permanent plastic deformation of the shock-absorbing seat rubber due to instantaneous overload, thereby ensuring its buffering performance. At the same time, the scissors lift platform drives the base frame mechanism to actively fit the bottom of the leg, further reducing the impact during the alignment process.

[0020] Assembly The system is assembled using the following steps: S1. Place the connected first channel steel and second channel steel on the top of the scissor lift platform for standby use, and place multiple sets of shock absorbing mechanisms at corresponding positions on the top of the second channel steel to complete the connection.

[0021] S2. After the shock-absorbing mechanism is installed, the unit mechanism is hoisted using a hoisting assembly, so that the unit mechanism is hoisted above the base mechanism and stops to prepare for assembly.

[0022] S3. The balancing component then assists in positioning the unit mechanism during hoisting, allowing the unit mechanism to remain stationary and balanced. The scissor lift then pushes the base frame mechanism upward to complete the assembly operation with the unit mechanism.

[0023] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up an extrusion rod, the extrusion rod is plugged into the rod body, and the positioning plate is plugged into the positioning groove. The connection of the shock absorber seat is achieved by using the plug-in locking method of the mechanical structure. There is no need to rely on bolts for fixing, which saves the tedious operation of screwing bolts in a narrow space and avoids the safety hazard of hand insertion.

[0024] (2) The extrusion rod is rotated to squeeze the convex tip of the outer wall of the extrusion rod against the horizontal part of the through hole, driving the rod body to tighten downward to achieve the tightening and positioning of the shock absorber seat. The positioning plate is inserted into the positioning groove and locked with a nut on one side of the first channel steel. This not only overcomes the hand operation in the narrow groove, but also ensures that the shock absorber seat is stable and shake-free through the coordinated locking of the mechanical structure, thereby improving operational safety.

[0025] (3) The bottom of the unit body is flexibly supported by two sets of L-shaped support plates and rubber pads of the supporting mechanism, which can stably control the posture of the unit mechanism during the lifting process, prevent the impact pressure generated when the first leg and the second leg are aligned with the shock-absorbing mechanism due to shaking, reduce the tearing or permanent plastic deformation of the shock-absorbing seat rubber due to instantaneous overload, and ensure its buffering performance.

[0026] (4) When assembling the unit mechanism and the chassis mechanism, the chassis mechanism is driven by the scissor lift to actively fit the bottom of the support leg. This method further reduces the impact during the alignment process and overcomes the situation where the shock absorber seat rubber is damaged due to instantaneous overload.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0042] See also Figures 1-12 , the present invention provides the following technical solutions: Example 1, see Figure 1 An open-frame generator set assembly system includes a hoisting assembly 1, an internal arrangement of a generator set mechanism 2, and the hoisting assembly 1 is used to hoist the generator set mechanism 2. The specific structure of the hoisting assembly 1 is as follows: See Figure 1 and Figure 2 The hoisting assembly 1 includes a frame 11. Two sets of slide rails are provided on the top of the frame 11. The tops of the two sets of slide rails are slidably connected with a transfer trolley 12. The transfer trolley 12 consists of a mobile frame, a motor and a gear. The motor drives the gear to rotate, and a rack is installed on the slide rail. When the gear rotates, it walks on the rack, thereby driving the mobile frame to move. An electric winch 13 is installed on the top of the transfer trolley 12. A chain hoisting mechanism 14 is hoisted at the bottom of the electric winch 13. The bottom of the chain hoisting mechanism 14 cooperates with the unit mechanism 2 for hoisting. The electric winch 13 can be a hoist, which is not specifically limited here. The transfer trolley 12 is used to drive the electric winch 13 and the chain lifting mechanism 14 to move. The electric winch 13 is used to pull the chain lifting mechanism 14 up and down. The chain lifting mechanism 14 is composed of a lifting plate and four chains. A lifting ring that cooperates with the chain lifting mechanism 14 is provided on the unit mechanism 2. The four chains are respectively connected to the corresponding lifting rings. When the chain lifting mechanism 14 moves up and down, the unit mechanism 2 can be lifted, which facilitates the lifting operation of the unit mechanism 2.

[0043] The unit mechanism 2 is hoisted and connected to the hoisting assembly 1. The specific structure of the unit mechanism 2 is as follows: See Figure 3-Figure 5 The unit mechanism 2 includes a unit body 21 and a first leg 22 and a second leg 23 connected to the bottom of the unit body 21. Multiple lifting rings are connected to the top of the unit body 21. The multiple lifting rings are all connected to the chain lifting mechanism 14. The unit body 21 is composed of a power unit (engine) and a generator and other structures, and the first leg 22 and the second leg 23 are used to support the unit body 21.

[0044] See Figure 4-Figure 9 The interior of the hoisting assembly 1 is provided with a chassis mechanism 5, which is used to connect with the first leg 22 and the second leg 23. The specific structure of the chassis mechanism 5 is as follows: See Figure 4-Figure 9 The chassis mechanism 5 includes two first channel steels 51 arranged below the frame 11, and two second channel steels 52 are connected between the two first channel steels 51. The first channel steels 51 and the second channel steels 52 cooperate to form the main frame of the chassis mechanism 5, and two shock-absorbing mechanisms 53 are arranged on the top of each second channel steel 52. Multiple shock-absorbing mechanisms 53 are arranged corresponding to the first leg 22 and the second leg 23, and the shock-absorbing mechanism 53 has the function of connecting the second channel steel 52 and the first leg 22 or the second leg 23.

[0045] See Figure 5-Figure 9 Each shock-absorbing mechanism 53 includes a shock-absorbing seat 531 arranged on the top of the corresponding second channel steel 52 and two second bolts 533 inserted into the shock-absorbing seat 531. The first leg 22 and the second leg 23 correspond to the two second channel steels 52, and the first leg 22 and the second leg 23 are respectively fitted with the tops of the two shock-absorbing mechanisms 53 above the corresponding second channel steel 52. There are two connecting holes on the tops of the first leg 22 and the second leg 23. The two connecting holes are arranged corresponding to the corresponding two shock-absorbing mechanisms 53. A first bolt 532 is arranged above each connecting hole. The bottom end of the first bolt 532 passes through the connecting hole and is threadedly connected to the corresponding shock-absorbing seat 531.

[0046] See Figure 5-Figure 9, a first bolt 532 is inserted into the connection hole on the first leg 22 and the second leg 23, and the first bolt 532 is threadedly connected to the corresponding shock-absorbing seat 531. In this way, the connection between the first leg 22 and the second leg 23 and the corresponding shock-absorbing seat 531 is realized, and the shock-absorbing seat 531 can be connected to the corresponding second channel steel 52 through the second bolt 533. When the chassis mechanism 5 is connected to the unit mechanism 2, the staff first places the shock-absorbing seat 531 at the position corresponding to the second channel steel 52, and then passes the second bolt 533 through the shock-absorbing seat 531 and the corresponding second channel steel 52. The bottom end of the second bolt 533 is screwed into the mating nut to complete the connection. When all the shock-absorbing mechanisms 53 are installed, the staff controls the height of the unit mechanism 2, and then drops the first leg 22 and the second leg 23 above the corresponding shock-absorbing seat 531. After placement is completed, the first bolt 532 is used to penetrate the corresponding first leg 22 or the second leg 23 and then threadedly connected to the corresponding shock-absorbing seat 531. When all the bolts are connected, the base frame mechanism 5 can be installed below the first leg 22 and the second leg 23, thereby realizing the assembly of the base frame mechanism 5 and the unit mechanism 2.

[0047] In the second embodiment, in order to ensure the flatness of the top surface of the chassis mechanism 5, the notch of the second channel steel 52 needs to be arranged downward, and the shock-absorbing mechanism 53 is installed on the top of the second channel steel 52 by bolts. Therefore, the staff needs to put their hands into the notch to screw the matching nut, and even need to use tools to screw. However, the space in some positions is small and it is difficult to put the hands in. Not only is the operation cumbersome, but it may also cause personal injury.

[0048] For this purpose, see Figure 5-Figure 9 The bottoms of the two second bolts 533 pass through the corresponding second channel steels 52 and are threadedly connected to the rod body 538. A through hole 537 is provided on the outer wall of each rod body 538. An extrusion rod 535 is passed through the inside of the through hole 537. The inner wall of the through hole 537 is provided with a horizontal portion and an arc-shaped portion. The horizontal portion is located below the arc-shaped portion. The cross-section of the extrusion rod 535 is cam-shaped, that is, the more round end of the extrusion rod 535 is the base circle portion, and the position of the outer wall of the extrusion rod 535 opposite to the base circle portion is the convex tip portion.

[0049] The top of the rod body 538 is provided with an internal thread groove adapted to the second bolt 533. Before the shock absorber seat 531 is installed, the second bolt 533 is first passed through the shock absorber seat 531, and then the rod body 538 is screwed on the thread of the second bolt 533. After that, the staff will place the shock absorber seat 531 on the top of the second channel steel 52, and the rod body 538 passes through the top of the corresponding second channel steel 52. At this time, in the same shock absorber seat 531, the through holes 537 on the two rod bodies 538 face the same direction. The operation method of this state is: the rod body 538 is screwed to the second bolt 533 through the thread. 33, adjust the through holes 537 on the two rod bodies 538 to a relative state, then pass the extrusion rod 535 through the corresponding through hole 537, and then screw the extrusion rod 535 so that the convex part of the extrusion rod 535 squeezes the horizontal position of the through hole 537. This extrusion method, even if there is a slight height difference between the two rod bodies 538, can make the rod body 538 bear downward force to pull the second bolt 533, and the second bolt 533 squeezes the shock absorber seat 531 downward, thereby firmly installing the shock absorber seat 531 on the top of the second channel steel 52.

[0050] See Figure 5-Figure 9 A positioning plate 5302 is connected to the outer wall of one end of the extrusion rod 535, and a screw is connected to the end of the positioning plate 5302 away from the extrusion rod 535, and a nut 5303 is threadedly connected to the outer wall of the screw. A rectangular groove 534 is opened on the side wall of the first channel steel 51 away from the second channel steel 52 and corresponding to the positioning plate 5302, and the positioning plate 5302 is adapted to the corresponding rectangular groove 534, and positioning grooves 536 are opened on the top and bottom surfaces of the side of the rectangular groove 534 close to the second channel steel 52. The two positioning grooves 536 are staggered and perpendicular to the corresponding rectangular grooves 534, and two fixing plates 539 are connected to the middle position of the bottom of the second channel steel 52. A through hole 5301 is opened on the side wall of the fixing plate 539, and one end of the extrusion rod 535 is inserted into the corresponding through hole 5301.

[0051] In order to fix the angle of the squeeze rod 535 after being screwed, the insertion method of the squeeze rod 535 is adjusted as follows: The shock-absorbing seat 531 is placed on the top of the second channel steel 52, and after the rod body 538 passes through the corresponding second channel steel 52, the staff will pass the extrusion rod 535 through the corresponding rectangular groove 534 on the first channel steel 51 and through the corresponding through hole 537. The extrusion rod 535 continues to extend to the inside of the corresponding through hole 5301. After the penetration is completed, the positioning plate 5302 on the extrusion rod 535 passes through the corresponding rectangular groove 534 at the same time. In this state, the corresponding rod body 538, the second bolt 533 and the shock-absorbing seat 531 are plugged in and fixed.

[0052] After the insertion is completed, the screw on the extrusion rod 535 is rotated, thereby driving the extrusion rod 535 to rotate inside the corresponding through hole 537. The convex tip of the extrusion rod 535 squeezes the horizontal part inside the through hole 537. After the extrusion rod 535 and the positioning plate 5302 are rotated 90 degrees, the rod body 538 is squeezed downward, causing the rod body 538 and the second bolt 533 to cooperate to tighten and position the shock absorber 531. Then, the extrusion rod 535 is pulled out. At this time, the rotated positioning plate 5302 is stuck in the two positioning grooves 536. Then, the nut 5303 is rotated on the screw, causing the nut 5303 and the positioning plate 5302 to cooperate to complete the angle and position fixation of the extrusion rod 535, ensuring that the shock absorber 531 will not shake. In addition, when the staff screws the nut 5303 and other bolts, it overcomes the situation where the staff has to put their hands into a narrow position, thereby improving the convenience of installation.

[0053] In the third embodiment, the assembly method of the unit mechanism 2 and the base mechanism 5 is to hoist the unit mechanism 2 and place it on the base mechanism 5. During the alignment process of the first leg 22 and the second leg 23 on the unit mechanism 2 with the corresponding shock-absorbing mechanism 53, the unit mechanism 2 will shake, causing part of the shock-absorbing mechanism 53 to bear a pressure far exceeding the design value in advance. The overload will cause the rubber of the shock-absorbing seat 531 to be instantly compressed and deformed too much, causing the internal structure to tear or permanent plastic deformation, and lose its buffering capacity.

[0054] Although the method of clamping the side wall of the unit mechanism 2 can ensure that the unit mechanism 2 remains stable, due to the complexity of the side wall structure of the unit body 21, the clamping method is not reasonable and is not suitable for the hoisting of the unit mechanism 2.

[0055] For this purpose, see Figure 1 On the basis of maintaining the original hoisting of the unit mechanism 2, a balancing component 3 and a scissor lift 4 are arranged below the frame 11. The scissor lift 4 is located above the balancing component 3, and the base frame mechanism 5 is arranged above the scissor lift 4, that is, the base frame mechanism 5 is raised by the scissor lift 4 during installation, and the balancing component 3 is used to adjust the angle and balance of the unit mechanism 2 in the hoisting state. Then the scissor lift 4 is used to drive the base frame mechanism 5 to adjust the height, so as to facilitate the subsequent assembly of the base frame mechanism 5 and the unit mechanism 2 in the balanced state.

[0056] participate Figure 10-12The balancing assembly 3 includes a track 31 and two mobile trolleys 32 slidably connected to the top of the track 31. An auxiliary mechanism 33 is installed on the top of each mobile trolley 32. The mobile trolley 32 is composed of a mobile frame, a motor and a gear. The motor drives the gear to rotate, and a rack is installed on the track 31. When the gear rotates, it walks on the rack, thereby driving the mobile frame to move. The auxiliary mechanism 33 is installed on the top of the mobile frame. The unit mechanism 2 is located between the two sets of auxiliary mechanisms 33. Two sets of supporting mechanisms 34 are provided on the opposite sides of the two auxiliary mechanisms 33. The supporting mechanism 34 is arranged toward the unit mechanism 2. The auxiliary mechanism 33 is used to adjust the position and height of the corresponding supporting mechanism 34. The supporting mechanism 34 is used to support the unit body 21, thereby adjusting the overall level of the unit mechanism 2, facilitating the splicing of the first leg 22 and the second leg 23 with the base frame mechanism 5, and can reduce the pressure degree of the single shock absorbing mechanism 53.

[0057] participate Figure 10-12 Each set of auxiliary mechanisms 33 includes a base 331 mounted on the top of the corresponding mobile trolley 32 and two uprights 332 symmetrically mounted on the top of the base 331. The same side of the two uprights 332 is connected to a guide rail 333. The same side of the two guide rails 333 is slidably connected to a lifting plate 337. Two lifting cylinders 334 are installed on the top of the base 331. The ends of the piston rods of the two lifting cylinders 334 are connected to a connecting plate 335. One side of the connecting plate 335 is connected to the lifting plate 337. The two sets of auxiliary mechanisms 33 corresponding to a set of auxiliary mechanisms 33 are connected. The supporting mechanism 34 is symmetrically arranged on the side wall of the lifting plate 337 facing the unit mechanism 2. The lifting cylinder 334 is used to push the connecting plate 335 up and down, thereby adjusting the height of the lifting plate 337. The lifting plate 337 slides on the guide rail 333 during the adjustment process, and the guide rail 333 cooperates to guide the lifting and lowering of the lifting plate 337. The lifting plate 337 drives the corresponding two groups of supporting mechanisms 34 to rise and fall when rising and falling. The supporting mechanism 34 can adjust the distance between it and the unit mechanism 2 when rising and falling, thereby supporting the unit mechanism 2.

[0058] participate Figure 10-12 Each supporting mechanism 34 includes an L-shaped support plate 342 arranged on the side wall of the corresponding lifting plate 337. A rubber pad 343 is installed on the top supporting surface of the L-shaped support plate 342. When the L-shaped support plate 342 supports the unit mechanism 2, the L-shaped support plate 342 extends to the lower position of the unit body 21, and then the lifting plate 337 is controlled to rise. When the lifting plate 337 rises, it drives the L-shaped support plate 342 to move synchronously, and then adjusts the height of the L-shaped support plate 342, so that the L-shaped support plate 342 can be supported at the lower position of the unit body 21.

[0059] Since the unit mechanism 2 will tilt due to the center of gravity during hoisting, and the multiple chains on the chain hoisting mechanism 14 cannot be adjusted in length, the unit body 21 is supported and lifted by the L-shaped support plate 342, thereby adjusting the overall tilt angle of the unit mechanism 2. During the adjustment process, the unit body 21 as a whole is gradually adjusted to a horizontal state. After the adjustment is completed, the scissors lift platform 4 drives the base frame mechanism 5 to move upward, causing the shock absorbing mechanism 53 to move closer to the first leg 22 and the second leg 23, thereby reducing the local overload caused by the gravity squeezing the shock absorbing mechanism 53 downward during hoisting of the unit mechanism 2.

[0060] participate Figure 10-12 A U-shaped frame 336 is installed on the side wall of the lifting plate 337, and one side of the two L-shaped support plates 342 is inserted between the U-shaped frame 336 and the lifting plate 337. One side of the L-shaped support plate 342 is connected to a U-shaped block 344, and the U-shaped block 344 is sleeved on the outer wall of the U-shaped frame 336. A threaded hole is opened on one side of the U-shaped block 344, and the internal thread of the threaded hole is connected to a locking bolt 341.

[0061] See Figure 1 、 Figure 11 and Figure 12 The two L-shaped supporting plates 342 corresponding to the same lifting plate 337 are kept at the same height. The two L-shaped supporting plates 342 corresponding to the same lifting plate 337 can also be called the L-shaped supporting plates 342 on the same side. When the L-shaped supporting plates 342 support the unit body 21, the staff can manually adjust the position of the L-shaped supporting plates 342 according to the required adjustment. The unit body 21 has an obvious tilt. The staff adjusts the position of the L-shaped supporting plate 342 at the bottom of the unit body 21. 2 slides to a position close to the other L-shaped supporting plate 342 on the same side. When the L-shaped supporting plate 342 moves, it drives the corresponding U-shaped block 344 to move. The U-shaped block 344 slides along the extension direction of the U-shaped frame 336, thereby adjusting the position of the L-shaped supporting plate 342. Through this arrangement, when the unit body 21 tilts, the unit body 21 is prevented from being deformed by excessive force on one side, thereby improving the strength of supporting the unit body 21.

[0062] Subsequently, the L-shaped support plate 342 in contact with the unit body 21 will generate a large extrusion pressure, and the L-shaped support plate 342 will gradually move upward. During the upward movement, the L-shaped support plates 342 on both sides and the rubber pads 343 on their tops first fit into the bottom of the unit body 21, and the lifting plate 337 continues to move upward. At this time, the L-shaped support plate 342 in contact with the unit body 21 will lift the tilted unit body 21, and the unit body 21 will gradually adjust to a relatively balanced state. After the adjustment is completed, the scissors lift 4 pushes the base frame mechanism 5 to move upward as a whole, causing the shock absorbing mechanism 53 to actively fit into the bottom position of the first leg 22 and the second leg 23. The active fitting method will reduce the situation where the downward gravity of the unit body 21 squeezes the shock absorbing mechanism 53 and causes local force overload.

[0063] Specifically, when the unit mechanism 2 adjusts its balance, it is achieved by the two moving trolleys 32 walking on the top of the track 31, so that the two sets of auxiliary mechanisms 33 can approach each other. At this time, the L-shaped supporting plate 342 moves to the bottom of the unit body 21 and is located between the first leg 22 and the second leg 23. After the adjustment is completed, the lifting cylinder 334 pushes the connecting plate 335 and the lifting plate 337 to move up, so that the two sets of supporting mechanisms 34 move up at the same time. During the upward movement, the L-shaped supporting plate 342 and the rubber pad 343 on its top first fit into the bottom of the unit body 21. However, due to the center of gravity problem of the unit body 21, the unit body 21 will tilt during hoisting. After the L-shaped supporting plate 342 is completely fitted with the bottom of the unit body 21, the lifting plate 337 continues to move up, and the L-shaped supporting plate 342 can The lower position of the group body 21 is lifted and the group body 21 is gradually adjusted to a relatively balanced state. After the adjustment is completed, the scissor lift platform 4 pushes the base frame mechanism 5 to move up as a whole, causing the shock absorber mechanism 53 to actively fit to the bottom position of the first leg 22 and the second leg 23. In this state, the first bolt 532 is passed through the corresponding connecting hole on the first leg 22 or the second leg 23, and threadedly connected to the inside of the shock absorber seat 531, thereby completing the assembly of the base frame mechanism 5 and the group mechanism 2. After the assembly is completed, the L-shaped support plate 342 moves down and separates from the group body 21, and the mobile trolley 32 drives the corresponding auxiliary mechanism 33 to move out from the bottom of the group body 21. After that, the scissor lift platform 4 moves down and separates from the base frame mechanism 5, and the hoisting assembly 1 moves the group mechanism 2 out from above the scissor lift platform 4 and places it on the ground.

[0064] In the fourth embodiment, the assembly system is assembled by the following steps: S1. Place the connected first channel steel 51 and second channel steel 52 on the top of the scissor lift 4 for standby use, and place multiple groups of shock absorbing mechanisms 53 on the corresponding positions on the top of the second channel steel 52 to complete the connection.

[0065] The more specific steps of S1 are: S11. Place the connected first channel steel 51 and second channel steel 52 on the top of the scissor lift 4, then insert the second bolts 533 into multiple groups of shock-absorbing seats 531, and then thread the rod body 538 onto the outer wall of the second bolts 533. After the connection is completed, place the shock-absorbing seat 531 on the top of the second channel steel 52, and the rod body 538 passes through the top of the corresponding second channel steel 52. At this time, in the same shock-absorbing seat 531, the through holes 537 on the two rod bodies 538 face the same direction.

[0066] S12. Then, the extrusion rod 535 is passed through the corresponding rectangular groove 534 on the first channel steel 51 and the corresponding through hole 537. The extrusion rod 535 continues to extend to the inside of the corresponding through hole 5301. After the passing is completed, the positioning plate 5302 on the extrusion rod 535 passes through the corresponding rectangular groove 534 at the same time. In this state, the corresponding rod body 538, the second bolt 533 and the shock absorber seat 531 are plugged in and fixed.

[0067] S13. After the plug-in is completed, the screw on the extrusion rod 535 is rotated, thereby driving the extrusion rod 535 to rotate inside the corresponding through hole 537. The convex tip part of the extrusion rod 535 squeezes the horizontal part inside the through hole 537. After the extrusion rod 535 and the positioning plate 5302 rotate 90 degrees, the rod body 538 is squeezed downward, causing the rod body 538 and the second bolt 533 to cooperate to tighten and position the shock absorber seat 531.

[0068] S14. Then, the extrusion rod 535 is pulled outward. At this time, the rotated positioning plate 5302 is stuck in the two positioning grooves 536. Then, the nut 5303 is rotated on the screw rod, so that the nut 5303 and the positioning plate 5302 cooperate to fix the angle and position of the extrusion rod 535, ensuring that the shock absorber seat 531 will not shake.

[0069] S2. After the damping mechanism 53 is installed, the unit mechanism 2 is hoisted by using the hoisting assembly 1, so that the unit mechanism 2 is hoisted above the base mechanism 5 and stops to prepare for assembly.

[0070] The more specific steps of S2 are: After S21 and the installation of the shock absorbing mechanism 53 is completed, the transfer trolley 12 drives the electric winch 13 and the chain lifting mechanism 14 to move, and the unit mechanism 2 to be assembled is placed at the lower position of the frame 11, and then the lock on the chain lifting mechanism 14 is connected with the lifting ring on the unit mechanism 2, and then the chain lifting mechanism 14 lifts the unit mechanism 2, and cooperates with the transfer trolley 12 to lift the unit mechanism 2 to the upper position of the base mechanism 5 and stay there for assembly.

[0071] S3. The balancing assembly 3 then assists in positioning the unit mechanism 2 during hoisting, so that the unit mechanism 2 can remain stationary and balanced. The scissor lift 4 then pushes the base mechanism 5 upward to complete the assembly operation with the unit mechanism 2.

[0072] The more specific steps for S3 are: S31, then the two moving trolleys 32 move on the top of the track 31, so that the two sets of auxiliary mechanisms 33 can approach each other. At this time, the L-shaped support plate 342 moves to the bottom of the unit body 21 and is located between the first leg 22 and the second leg 23.

[0073] S32. After the adjustment is completed, the lifting cylinder 334 pushes the connecting plate 335 and the lifting plate 337 upward, causing the two sets of supporting mechanisms 34 to move upward at the same time. During the upward movement, the L-shaped supporting plate 342 and the rubber pad 343 on its top first fit into the bottom of the unit body 21. However, due to the center of gravity problem of the unit body 21, the unit body 21 will tilt during hoisting. After the L-shaped supporting plate 342 on the same side is completely fitted into the bottom of the unit body 21, the lifting plate 337 continues to move upward, and the L-shaped supporting plate 342 can lift the lower position of the unit body 21.

[0074] S33, the unit body 21 is gradually adjusted to a relatively balanced state. After the adjustment is completed, the scissors-type lifting platform 4 pushes the base frame mechanism 5 to move up as a whole, causing the shock-absorbing mechanism 53 to actively fit to the bottom position of the first leg 22 and the second leg 23. In this state, the first bolt 532 is passed through the corresponding connecting hole on the first leg 22 or the second leg 23, and threadedly connected to the inside of the shock-absorbing seat 531, thereby completing the assembly of the base frame mechanism 5 and the unit mechanism 2. After the assembly is completed, the L-shaped support plate 342 moves down and separates from the unit body 21, and the mobile trolley 32 drives the corresponding auxiliary mechanism 33 to move out from the bottom of the unit body 21. After that, the scissors-type lifting platform 4 moves down and separates from the base frame mechanism 5, and the hoisting assembly 1 moves the unit mechanism 2 out from above the scissors-type lifting platform 4 and places it on the ground.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
