Description

Technical Field

[0001] This invention relates to the field of leveling device technology, and in particular to a high-efficiency and fast leveling device for lifting machinery. Background Technology

[0002] During the installation and use of lifting machinery such as tower cranes and gantry cranes, ensuring that their support bases are precisely level is crucial. Uneven mounting bases will lead to uneven stress on the lifting machinery, which will not only affect operational stability and lifting accuracy, but also accelerate structural fatigue and bring serious safety hazards.

[0003] Currently, the traditional method for leveling lifting machinery typically involves manual measurement using tools such as spirit levels and dial indicators, followed by repeated adjustments to different points on the support base using jacks or shims. This method has the following drawbacks: First, the manual measurement and adjustment process is cumbersome and time-consuming, and its accuracy depends heavily on the operator's experience, resulting in low efficiency. Second, the leveling devices used are mostly independent tools, lacking integrated design with horizontal reference and movement functions, leading to inconvenience in on-site handling and positioning, poor overall operational continuity, and impacting construction efficiency.

[0004] Therefore, this application aims to provide a leveling device that integrates horizontal reference, multi-point adjustment, movement and fixing functions to solve the technical problems of cumbersome operation, low efficiency and inconvenient movement and positioning of the leveling process of existing lifting machinery. Summary of the Invention

[0005] The main objective of this invention is to provide a high-efficiency and fast leveling device for lifting machinery to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a high-efficiency and fast leveling device for lifting machinery is provided, comprising a mounting base for mounting the lifting machinery, and further comprising: A reference component, located below the mounting base, is used to determine whether the mounting base is level. An adjustment component is also located below the mounting base and connected to different parts of the bottom surface of the mounting base. The mounting base can be leveled by adjusting the component. A support component is provided below the adjustment component to support the adjustment component on the ground; The rolling components are multiple in number and are all located below the support component. They can move up and down along the support component. When the rolling component contacts the ground, it can roll on the ground to move the leveling device. When the rolling component leaves the ground, the support component contacts the ground to fix the leveling device on the ground.

[0007] Furthermore, the support assembly includes a base with an installation groove inside. Several hydraulic cylinders are fixedly installed in the installation groove. The piston rods of the hydraulic cylinders face downwards and slide through the bottom of the base. A support circular plate is fixedly installed at the end of the piston rod of the hydraulic cylinder.

[0008] Furthermore, the rolling assembly includes a pulley, a translation assembly, and a locking assembly. The translation assembly is used to drive the pulley to slide back and forth on the base, and the locking assembly is used to mount the pulley on the translation assembly.

[0009] Furthermore, the translation component includes several bidirectional lead screws, each with a moving block threaded to both ends. Each moving block has a trapezoidal extrusion groove below it, and a branch rod is slidably disposed within each extrusion groove.

[0010] Furthermore, the branch rod slides through the lower surface of the base, and the locking assembly is located at the bottom end of the branch rod and outside the base.

[0011] Furthermore, the locking assembly includes a concave block, and each of the two legs of the concave block is threaded with a locking rod. Each locking rod is provided with a T-shaped block, and the two T-shaped blocks arranged opposite each other are used to install pulleys.

[0012] Furthermore, the adjustment assembly includes several fixed sleeves, the bottom of which is fixedly connected to the base. A lifting cylinder is fixedly installed inside the fixed sleeve, and the piston rod of the lifting cylinder extends from the opening above the fixed sleeve and is hinged to the bottom surface of the mounting base.

[0013] Furthermore, the reference component includes two fixed plates fixedly disposed on the upper surface of the base, and a rotating shaft is rotatably connected between the two fixed plates, with a gravity block fixedly disposed on the rotating shaft.

[0014] Furthermore, an L-shaped rod is fixedly provided at the end of the rotating shaft extending outside the fixed plate, and a perforated plate is slidably sleeved on the outer ring of the horizontal section of the L-shaped rod. The perforated plate is fixedly connected to the fixed plate by bolts, and a positioning frame is provided at the top of the L-shaped rod.

[0015] Furthermore, a positioning frame is fixedly provided at the bottom of the mounting base. By observing whether the positioning frame is parallel to the positioning frame, it can be determined whether the leveling device is level.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating the reference components, multi-point independently adjustable lifting cylinders, and intuitive positioning frame observation method into one unit, operators can complete the leveling status judgment and precise adjustment on the device in one go, without having to repeatedly change measuring tools and lifting tools. This significantly simplifies the operation process and improves the efficiency and accuracy of leveling operations.

[0017] 2. Through the innovative telescopic rolling components, the device can quickly and stably switch between the "moving state" with the pulleys on the ground and the "fixed working state" with the supporting circular plate on the ground and the pulleys off the ground. This solves the problem of difficult transportation of large leveling devices, facilitates quick positioning on the construction site, and provides stable rigid support during operation, ensuring the reliability of leveling operations.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] This embodiment provides a highly efficient and quick leveling device for lifting machinery, such as... Figure 1 and Figure 2 As shown, it includes a support assembly, a rolling assembly, an adjusting assembly, a reference assembly, and a mounting base 6 for mounting the lifting machinery.

[0022] The support assembly includes a base 1, which is a plate-like or frame-like structure with sufficient rigidity and strength. For example... Figures 5 to 8 As shown, a mounting groove 18 is provided inside the base 1. Several hydraulic cylinders 21 are fixedly installed within the mounting groove 18. The piston rods of these hydraulic cylinders 21 are arranged vertically downwards, and the ends of the piston rods slide through the bottom plate of the base 1. A support circular plate 20 is fixedly connected to the end of the piston rod of each hydraulic cylinder 21. When the piston rods of all hydraulic cylinders 21 extend synchronously, the support circular plate 20 presses downwards against the ground, thereby lifting the entire base 1 off the ground and placing the device in a stable supported state.

[0023] A rolling assembly is used to facilitate the movement of the device. The rolling assembly includes a pulley 26, a translational assembly for driving the pulley 26 up and down, and a locking assembly for mounting the pulley 26. The translational assembly includes two transversely arranged bidirectional lead screws 25. The bidirectional lead screws 25 are rotatably mounted on the base 1 via bearing seats and are driven to rotate by a motor installed in the base 1. A moving block 24 is threaded onto each of the two reverse threads of the bidirectional lead screws 25. A trapezoidal extrusion groove 28 is formed below the moving block 24. A limiting groove 23 is also formed on the upper surface of the base plate of the base 1. The upper part of the moving block 24 is embedded in the limiting groove 23 and can slide along it, thereby restricting the moving block 24 to only move horizontally and not rotate. A branch rod 27 is slidably disposed within each extrusion groove 28. The upper end of the branch rod 27 is located within the extrusion groove 28, and the lower end slides through the base plate of the base 1 and extends below it. Inside the base 1, a concave plate 22 is fixedly connected to the position corresponding to each branch rod 27. The branch rod 27 passes through the concave plate 22 and can slide relative to it. To provide a restoring force, a spring 29 is sleeved around the branch rod 27. One end of the spring 29 is fixedly connected to the upper surface of the base plate of the base 1, and the other end is fixedly connected to the top end of the branch rod 27.

[0024] A locking assembly is connected to the bottom end of branch rod 27. The locking assembly includes a concave block 19. The inner sides of the two vertical legs of the concave block 19 are used to clamp the pulley 26. A locking rod 30 is threaded onto each of the two legs. A T-shaped block 32 is threaded onto the inner end of each locking rod 30. The two T-shaped blocks 32 are arranged opposite to each other. The pulley 26 is mounted between the two T-shaped blocks 32 via a fixed shaft 31. Specifically, the opposite inner sides of the T-shaped blocks 32 have grooves for receiving the ends of the fixed shaft 31, and the other ends are machined with threaded grooves adapted to the locking rods 30, which can be screwed into the threaded grooves and connected to the T-shaped blocks 32. During installation, place the T-block 32 inside the two legs of the concave block 19. Screw the locking rod 30 into the T-block 32 from the outside of the concave block 19 to fix the locking rod 30 and the T-block 32 onto the concave block 19. Then, align the fixing shafts 31 on both sides of the pulley 26 with the grooves inside the T-block 32. Continue to rotate the locking rod 30 to screw it onto the concave block 19 and push the T-block 32 closer to the pulley 26 until the fixing shaft 31 extends into the groove, completing the installation of the pulley 26. When it is necessary to remove the pulley 26, turn the locking rod 30 in the opposite direction to move the T-block 32 away from the pulley 26 until the fixing shaft 31 comes out of the groove, making it convenient to replace the pulley 26.

[0025] The adjustment assembly is used to precisely adjust the height of the mounting base 6 to achieve leveling. The adjustment assembly includes multiple retaining sleeves 8. Each retaining sleeve 8 is vertically fixed to the upper surface of the base 1. A lifting cylinder 10 is fixedly installed inside each retaining sleeve 8. The piston rod of the lifting cylinder 10 extends upwards from the top of the retaining sleeve 8, and its end is connected to the bottom surface of the mounting base 6 via a ball joint or universal joint. By independently controlling the extension and retraction of the piston rod of each lifting cylinder 10, the height of the corresponding position of the mounting base 6 can be precisely adjusted.

[0026] The reference assembly provides an absolute horizontal reference. The reference assembly includes two fixed plates 2 mounted on the upper surface of the base 1. A rotating shaft 12 is rotatably connected between the two fixed plates 2 via bearings. A gravity block 9 is fixedly mounted in the middle of the rotating shaft 12. An L-shaped rod 4 is fixedly connected to each end of the rotating shaft 12 extending beyond the fixed plates 2. The horizontal section of the L-shaped rod 4 is fixed to the rotating shaft 12, and the vertical section extends upwards. Because the gravity block 9 is always held vertically downwards by gravity, the rotating shaft 12 and the vertical section of the L-shaped rod 4 fixed to it also always remain vertical. Figure 4 As shown, a perforated plate 3 is slidably fitted onto the horizontal section of the L-shaped rod 4. The horizontal section of the L-shaped rod 4 is preferably rectangular, and the through hole in the center of the perforated plate 3 is also a corresponding rectangle to prevent relative rotation. The perforated plate 3 can be fixedly connected to the fixing plate 2 by bolts 17. Once the perforated plate 3 is fixed, the vertical state of the L-shaped rod 4 can be locked. Figure 3As shown, a positioning frame 11 is installed at the top of the vertical section of the L-shaped rod 4 via an adjustable connection structure. Specifically, the top of the L-shaped rod 4 has a slot 13 and a support plate 15 to support the positioning frame 11. The positioning frame 11 can be pressed and fixed by passing a threaded rod 16 through the positioning frame 11 and screwing it into the threaded hole at the top of the L-shaped rod 4. A pressing circular plate 14 can also be provided at the head of the threaded rod 16 to increase the contact area and ensure that the positioning frame 11 is firmly fixed. When the L-shaped rod 4 is locked in the vertical position, the positioning frame 11, which is fixed vertically to it, is in an absolutely horizontal position, serving as a reference for leveling.

[0027] Mounting base 6 is used to support the lifting machinery to be installed. At the bottom of mounting base 6, a positioning frame 7 is fixedly installed corresponding to the position of positioning bracket 11. A transparent level box 5 is also fixedly installed on one side of mounting base 6. The box contains a colored liquid and is marked with horizontal scale lines, which can be used to assist in quickly determining the levelness.

[0028] The working process of this invention is as follows: 1. Movement and Positioning Start the motor that drives the bidirectional lead screw 25, causing the two moving blocks 24 to move towards each other. The inclined surface of the pressing groove 28 presses the branch rod 27 downward, compressing the spring 29, and finally pushing the pulley 26 downward to contact the ground, lifting the base 1. At this point, the device can be easily pushed to the predetermined working position.

[0029] 2. Preparation for fixing and leveling Activate hydraulic cylinder 21 to extend support plate 20 and press it firmly against the ground. At this time, base 1 is stably supported, and pulley 26 is off the ground. Then, operate the reference assembly: loosen bolt 17 to allow gravity block 9 to hang freely, causing L-shaped rod 4 to be in a vertical position. Move perforated plate 3 to fit tightly against fixing plate 2, and then tighten bolt 17 to lock L-shaped rod 4. Next, place positioning bracket 11 on top of L-shaped rod 4 and tighten threaded rod 16 to fix it in a horizontal position.

[0030] 3. Leveling operation Observe the gap between the positioning frame 7 at the bottom of the mounting base 6 and the horizontal positioning frame 11. If the gap is too large, activate the corresponding lifting cylinder 10 to lift that part of the mounting base 6. At the same time, you can also observe the liquid level in the transparent box 5. Repeatedly adjust each lifting cylinder 10 until the lower surface of the positioning frame 7 is completely in contact with the upper surface of the positioning frame 11, and the liquid level in the transparent box 5 is parallel to the scale line, which indicates that the mounting base 6 has reached a horizontal state.

[0031] 4. Slippage Maintenance When it is necessary to replace pulley 26, with the device supported by hydraulic cylinder 21, operate the motor to move the moving block 24 to a position where pulley 26 is suspended. Then loosen the locking rod 30 to release the T-block 32 from clamping the fixed shaft 31, and the old pulley 26 can be removed and replaced with a new pulley 26.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
