Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic electromechanical equipment hoisting equipment, and in particular to a hydraulic electromechanical equipment hoisting system. Background Art

[0002] Traditional lifting methods and equipment are difficult to meet the needs of modern hydraulic electromechanical equipment lifting. It is necessary to adopt more stable lifting processes, such as servo-controlled lifting and hydraulic lifting, combined with precise measurement and control technology to ensure the safety and accuracy of equipment lifting.

[0003] For example, Chinese patent document CN116675130A discloses an electromechanical installation system and method, which adopts a servo-controlled lifting process. The system uses a winding mechanism to wind up the wire rope, so that the wire rope is guided and transported under the action of a first pulley and a second pulley, and the position of the first shaft is adjusted by a first servo motor, a screw rod, and a movable roller, so that the electromechanical equipment can effectively adjust its horizontal position when it is hoisted by the winding mechanism. A plurality of first pulleys are provided, which can simultaneously clamp and lift the electromechanical equipment at multiple angles to maintain balance and stability. The disadvantage is that when the first pulley is moved to align and install the equipment, the length of the wire rope located on the lower side of the first pulley will change, resulting in a change in the height of the heavy object. It is necessary to simultaneously control the rotation of the winding mechanism to ensure the installation height. Due to the different number of wire rope winding layers on the winding mechanism, the diameter during winding is different, and the height of the heavy object cannot be accurately controlled.

Its features are: the design of hydraulic arm and stepper motor, the device can accurately control the lifting position, and is more labor-saving and flexible; its disadvantages are: its structural stability is poor, when clamping heavier electromechanical equipment, the beam is prone to tilt and shaking problems, affecting the installation accuracy.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] It should be noted that references in the specification to "one embodiment," "an embodiment," "exemplary embodiments," "some embodiments," etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment will include such specific features, structures, or characteristics. Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, it is within the knowledge of persons skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0028] Example 1: See also Figure 1-10 , a water conservancy electromechanical equipment lifting system, comprising: a lifting assembly 1, the lifting assembly 1 includes a hydraulic lifting arm 11 and a mobile base 12, the hydraulic lifting arm 11 is fixedly mounted on the mobile base 12, the top of the hydraulic lifting arm 11 has a connecting section 14, the connecting section 14 passes through the hole on the fixed block 13, and then the end cover limit is fixedly installed on the top of the connecting section 14, the fixed block 13 is fixedly connected to a lifting frame 15 at one end away from the adjusting assembly 2, and the other end is connected to the adjusting assembly 2; the lifting frame 15 is used to install the sling assembly 3; the adjusting assembly 2 includes a shell 21, a lifting block 23 is slidingly provided inside the shell 21, an adjusting gear 24 is rotatably mounted on the top or bottom of the lifting block 23, the outer wall of the adjusting gear 24 is radially fixed with a first telescopic mechanism 4, and the end of the first telescopic mechanism 4 away from the adjusting gear 24 is connected to the fixed block 13; a driver 25 is fixedly mounted on the lifting block 23, and a main gear 26 is mounted on the output shaft of the driver 25, and the main gear 26 is meshed with the adjusting gear 24.

[0029] The mobile base 12 is used to support the hydraulic lifting arm 11 and can move on a flat ground. The hydraulic lifting arm 11 lifts the fixed block 13, thereby lifting the equipment. The outer shell 21 is placed on the ground and has good stability. The lifting block 23 slides inside the outer shell 21. The lifting block 23 not only stabilizes the lifting frame 15, making the lifting frame 15 less likely to shake, but also acts as a counterweight. When the lifting frame 15 needs to be swung left and right for adjustment, the driver 25 drives the main gear 26 to rotate, thereby driving the adjustment gear 24 to rotate. Since the outer shell 21 has a certain width in the window located in the first telescopic mechanism 4, the first telescopic mechanism 4 can swing within the window width range, which is convenient for adjusting the installation angle of the equipment during lifting.

[0030] The hoisting system has good stability. During the lifting and installation of electromechanical equipment, the lifting frame 15 is not prone to tilting or shaking. The electromechanical equipment has good stability, which improves the installation accuracy and facilitates the docking, installation and placement of the electromechanical equipment.

[0031] Further, see Figure 2 A central shaft 22 is longitudinally mounted in the housing 21, and a lifting block 23 and an adjusting gear 24 are slidably mounted on the central shaft 22. By providing the central shaft 22, the stability of the lifting block 23 sliding up and down is improved.

[0032] exist Figure 2 In the figure, the outer side of the central shaft 22 is provided with a support spring 28 located between the outer shell 21 and the lifting block 23. The top of the main gear 26 is provided with a pressure plate 27 that fits with the adjustment gear 24. The lifting block 23 slides stably up and down on the outer side of the central shaft 22. After descending, it is buffered by the support spring 28.

[0033] Furthermore, a vertical slot is formed on the outer side of the lifting block 23, and a slide rail 9 is installed on the inner wall of the housing 21 at a position corresponding to the vertical slot. A pulley 10 is provided inside the slide rail 9 for rotation, and the slide rail 9 extends into the vertical slot. The lifting block 23 moves more stably along the slide rail 9.

[0034] See also Figure 2 The outer side of the first telescopic mechanism 4 is fixed with a telescopic connecting rod 8 fixed to the telescopic end of the hydraulic lifting arm 11. The telescopic connecting rod 8 is used to strengthen the stability of the connection between the first telescopic mechanism 4 and the fixed block 13. The telescopic connecting rod 8 can adopt a telescopic structure similar to the boom of a truck crane.

[0035] In this embodiment, the first telescopic mechanism 4 is a hydraulic cylinder, and the driver 25 is a reduction motor or a servo motor.

[0036] Example 2: Based on Example 1, a rotating platform 5 is fixed to the bottom end of the housing 21 and rotatably mounted on the base 6. This facilitates circumferential rotation of the crane frame 15 during lifting, providing a larger working surface. The rotating platform 5 utilizes existing technology, such as a rotating structure used in tower cranes.

[0037] In order to improve the stability of the adjustment component 2, a counterweight safety component 7 is provided on the outside of the base 6; the counterweight safety component 7 includes a base plate 71 and an extension plate 72, the base plate 71 is fixedly connected to one side of the base 6, and the extension plate 72 is hingedly installed on the upper side of the base plate 71, and the hinge point is away from the base 6, and a support leg 73 is fixed on the extension plate 72. When the extension plate 72 is flipped open, the support leg 73 supports the ground; the base plate 71 and the extension plate 72 are used to place a counterweight object 74.

[0038] Example 3: On the basis of Example 1 or Example 2, see Figure 5 、 6 , 7, 8, the hoist assembly 3 includes a connecting base 110, a bracket 31 fixedly mounted at its lower end. Adjustment blocks 33 are mounted at each end of the bracket 31. A turret 34 is connected to the lower end of the adjustment blocks 33. Clamping jaws 35 are pivotally mounted within the turret 34, with the jaws 35 facing each other. The adjustment blocks 33 can be adjusted on the bracket 31, thereby adjusting the spacing between the clamping jaws 35 to accommodate various equipment sizes.

[0039] Specifically, the bracket 31 is provided with guide slots 32 on both sides of the connecting base 110. The lower side of the guide slots 32 is provided with multiple grooves. The adjustment block 33 is a U-shaped groove structure. The adjustment block 33 is clamped to the lower side of the bracket 31 from below. A crossbar is installed on the adjustment block 33 and passes through the guide slots 32. By placing the crossbar on the adjustment block 33 into different grooves, the spacing between the two side clamping jaws 35 can be adjusted.

[0040] Furthermore, the sling assembly 3 also includes a sling seat 18, with positioning frames 19 fixedly connected to both sides of the lower end of the sling seat 18. Two connecting seats 110 are respectively connected to the two positioning frames 19. A second telescopic mechanism 39 is fixedly installed at the bottom of the sling seat 18. The telescopic end of the second telescopic mechanism 39 extends downward. The telescopic end of the second telescopic mechanism 39 is installed with a side frame 38. The lower end of the side frame 38 extends downward from both sides of the bracket 31. One end of the two connecting rods 37 is pivotally hinged to the lower end of the side frame 38. The end of the clamping jaw 35 connected to the rotating frame 34 is provided with an extension section 36. The other ends of the two connecting rods 37 are respectively pivotally hinged to the extension sections 36 on the two side clamping jaws 35. The extension and contraction of the second telescopic mechanism 39 drives the clamping jaws 35 on both sides to open and close, thereby controlling the clamping jaws 35 on both sides to automatically open and grasp the load, making it more flexible to use.

[0041] like Figure 5 As shown, when the telescopic end of the second telescopic mechanism 39 is extended, the side frame 38 moves downward and the clamping claws 35 on both sides are opened; when the telescopic end of the second telescopic mechanism 39 is retracted, the side frame 38 moves upward and the clamping claws 35 on both sides are closed.

[0042] In this embodiment, the second telescopic mechanism 39 is a pneumatic cylinder or a hydraulic cylinder.

[0043] Example 4: Based on Example 3, see Figure 8 、 9 , 10. A cavity is provided at the end of the clamping jaw 35, and a buffer plate 310 is rotatably installed in the cavity. A connecting plate 311 is pivotally hinged on the lower side of the buffer plate 310, and the connecting plate 311 is hinged to one end of the horizontal axis 312. A sliding hole is provided in the cavity of the clamping jaw 35, and the other end of the horizontal axis 312 passes through the sliding hole. The horizontal axis 312 is provided with a spring 313 between the connecting plate 311 and the clamping jaw 35.

[0044] When the telescopic end of the second telescopic mechanism 39 retracts, the clamping claw 35 is clamped on the outside of the electromechanical device, and the spring 313 on the outside of the buffer plate 310 is used to buffer the clamping claw 35 to prevent it from directly hitting the electromechanical device, thereby protecting the electromechanical device.

[0045] Example 5: On the basis of Example 1 or 2 or 3 or 4, see Figure 1 、 2 , 3, 4, a sliding block 17 is also fixedly mounted on the spreader seat 18. The sliding block 17 can be cylindrical or rectangular. The lifting frame 15 is provided with a transverse slideway. The sliding block 17 is slidably connected to the slideway on the lifting frame 15. The lifting frame 15 is installed with a push-pull device (not shown in the figure). The push-pull device is connected to the sliding block 17 to adjust the position of the spreader assembly 3. The push-pull device drives the sliding block 17, thereby accurately adjusting the position of the spreader assembly 3.

[0046] In this embodiment, the push-pull device can adopt a screw structure. Specifically, the screw passes through the sliding block 17, and the screw is screwed together with the sliding block 17 by threads. A servo motor is installed at the outer end of the lifting frame 15, and the output shaft of the servo motor is connected to the screw. The servo motor drives the screw to rotate, thereby driving the sliding block 17 to move precisely, so that the sling assembly 3 and the equipment can be accurately moved and adjusted.

[0047] Bolts 16 are installed at the ends of the lifting frame 15. Bolts 16 can be used to install a servo motor or a mounting plate for a hydraulic cylinder. When a servo motor is installed, a screw drives a sliding block 17; when a hydraulic cylinder is used, the piston rod of the hydraulic cylinder is connected to the sliding block 17 to drive the sliding block 17.

[0048] The use steps of the present invention are as follows: During the hoisting construction of hydraulic electromechanical equipment, the mobile base 12 in the lifting assembly 1 is moved to the construction area, and the sliding block 17 inside the guide frame 15 is moved, thereby adjusting and changing the sliding block 17 and the sling assembly 3 below to move the horizontal position.

[0049] The hydraulic lifting arm 11 descends, the rotating platform 5 rotates, and at the same time, the first telescopic mechanism 4 extends and contracts. The lifting assembly 1 follows the mobile support crane 15, lowering the sling assembly 3 to the outside of the electromechanical equipment. The second telescopic mechanism 39 pushes the side frame 38 structure at the output end downward, thereby pushing the connecting rod 37 connected to the other end to deflect, and then pushing the extension section 36 structure at the other end to deflect, controlling the clamping claw 35 structure to rotate inside the rotating frame 34, controlling the clamping claw 35 to open, clamping on the outside of the electromechanical equipment, and completing the clamping limit. When hoisting electromechanical equipment of different sizes, the adjustment block 33 round rod structure located inside the guide groove 32 of the bracket 31 can be moved to different grooves to complete the adjustment of the distance between the two clamping claws 35, and flexibly clamp and position electromechanical equipment of different sizes.

[0050] During clamping, the buffer plate 310 at the end of the clamping jaw 35 impacts the outside of the electromechanical device, and the spring 313 outside the transverse axis 312 cushions and clamps the electromechanical device, protecting it. After clamping is complete, the hydraulic lift arm 11 rises, controlling the synchronous rise of the fixed block 13 and the first telescopic mechanism 4. The adjustment gear 24 is then able to rise outside the central axis 22. The lift block 23 ascends along the slide rail 9, with the pulley 10 reducing friction and ensuring a more stable rise.

[0051] The rotating platform 5 rotates, simultaneously coordinating with the extension and retraction of the first telescopic mechanism 4. The lifting assembly 1 follows the mobile support gantry 15, hoisting the electromechanical equipment to the installation area. The hydraulic lifting arm 11 lowers, controlling the clamping jaws 35 of the clamp assembly 3 to lower the electromechanical equipment to the placement area. During installation, the main gear 26 at the end of the main shaft rotates via the driver 25, engaging the outer adjustment gear 24, causing the gantry 15 to slightly swing and the slide block 17 to move for alignment, before final assembly.
