Description

Technical Field

[0001] This invention relates to the field of building jacking construction technology, specifically to a high-precision multi-point synchronous hydraulic jacking system and its usage method. Background Technology

[0002] A building construction machine is a type of construction equipment that typically includes a lifting mechanism to raise the building platform. By lifting the platform, construction can be carried out on different parts of the building at different heights. Currently, when the lifting mechanism is used to lift the building platform at multiple points, it is easy to cause different lifting heights at each point, which can easily lead to tilting or even accidents.

[0003] A search revealed a pump-controlled and valve-controlled hydraulic jacking system with authorization announcement number CN115370629B. This invention employs a pump-controlled + valve-controlled system to prevent jacking operations from failing if a single electrically controlled pump malfunctions. A balance valve ensures cylinder synchronization accuracy; a flow divider / combiner valve also ensures cylinder synchronization accuracy; a two-position three-way solenoid valve enables single-acting cylinders; and a pilot control valve enables two-stage pilot oil control, preventing abnormal opening of the balance valve.

[0004] However, the existing lifting structures mentioned above cannot achieve the same lifting force at multiple points when lifting the construction machine platform due to the large size of the platform. The lifting force of several lifting cylinders varies greatly, which not only affects the construction but also poses safety hazards. Therefore, we propose a high-precision multi-point synchronous hydraulic lifting system and its usage method. Summary of the Invention

[0005] This invention proposes a high-precision multi-point synchronous hydraulic jacking system and its usage method, which solves the problem mentioned in the background art that existing jacking structures cannot achieve the same jacking force at multiple points during the jacking process when jacking the construction machine platform. Due to the large size of the platform, the jacking force of several jacking cylinders varies greatly, which not only affects the construction but also poses safety hazards.

[0006] The technical solution of the present invention is as follows:

[0007] A high-precision multi-point synchronous hydraulic jacking system includes a jacking frame, a point monitoring controller at the end of the jacking frame, a main hydraulic rod at the lower end of the jacking frame, a jacking plate connected to the top of the jacking frame, a fine-tuning structure between the jacking plate and the jacking frame, a reinforcing structure on the outer surface of the jacking plate, and a pressure sensor installed in the groove opening at the upper end of the jacking plate.

[0008] The fine-tuning structure includes a movable frame slidably connected to the upper end of the lifting frame, an inner guide rod fixedly connected to the lower end of the movable frame, a fine-tuning hydraulic rod connected to the top end of the lifting frame, a positioning kit movably sleeved on the outer surface of the fine-tuning hydraulic rod near the output end, and a stabilizing rod fixedly connected between the positioning kit and the top end of the lifting frame.

[0009] An anti-detachment component is provided between the movable frame and the lifting frame.

[0010] As a further technical solution of the present invention, the reinforcing structure includes an extension plate fixedly connected to the lower end of the lifting plate, a positioning post fixedly connected to the lower end of the extension plate, a connecting hole opened on the outer surface of the extension plate corresponding to the positioning post, a reinforcing plate movably connected to the outer surface of the extension plate, a connecting post fixedly connected to the lower end of the reinforcing plate, and an extension component provided inside the reinforcing plate.

[0011] As a further technical solution of the present invention, the extension component includes movable rods slidably disposed on the outer surfaces of both ends of the reinforcing plate, a pressing column slidably disposed on the upper end of the reinforcing plate, the pressing column and the movable rod being chamfered at their respective corners, a transverse groove being formed inside the reinforcing plate near the middle of the movable rod, a transverse protruding plate being fixedly connected to one end of the outer surface of the movable rod corresponding to the inner side of the transverse groove, a return spring being disposed on one side of the transverse protruding plate inside the transverse groove, a vertical groove being formed inside the reinforcing plate near the middle of the pressing column, and a longitudinal protruding plate being fixedly connected to the outer surface of the pressing column corresponding to the inner side of the vertical groove.

[0012] As a further technical solution of the present invention, the lower end of the inner guide rod is inserted into the interior of the lifting frame and is slidably connected to the lifting frame. The length of the inner guide rod is greater than the maximum extension length of the fine-tuning hydraulic rod. The number of the stabilizing rods is several groups and they are distributed in a ring array. The output end of the main hydraulic rod is fixedly connected to the lower end of the lifting frame, and the lifting frame is pushed by the extension of the main hydraulic rod.

[0013] As a further technical solution of the present invention, the pressure sensors are in several groups and arranged in a ring array. The positioning kit is kept stable with the lifting frame by a stabilizing rod. The output end of the fine-tuning hydraulic rod is fixedly connected to the lower end of the lifting plate. The pressure sensors, the lifting frame and the point monitoring controller are all electrically connected.

[0014] As a further technical solution of the present invention, the connecting hole extends through the extension plate and the positioning post, the diameter of the connecting post is equal to the diameter of the connecting hole, and the thickness of the reinforcing plate is equal to the distance between the extension plate and the upper end of the lifting plate.

[0015] As a further technical solution of the present invention, the contact surface between the building construction machine operation platform and the lifting plate is increased by the reinforcing plate, the number of the positioning columns is several groups and they are distributed in an array, the number of the connecting columns is equal to the number of the positioning columns, and their positions correspond one-to-one.

[0016] As a further technical solution of the present invention, the number of the extension components is several groups and they are arranged in an array. The movable rod has an "L" shaped structure, and the upper end of one side of the movable rod is flush with the upper end of the reinforcing plate. The movable rod moves away from the pressing column by pressing it down. The movable rod moves to the side of the pressing column when there is no external force pressing the pressing column by the reaction force of the return spring.

[0017] As a further technical solution of the present invention, the anti-detachment component includes an extension rod fixedly connected to the outside of the lifting frame. A positioning block is fixedly connected to the upper end of the extension rod. A through hole is opened on the outer surface of the positioning block. A limit block is fixedly connected to the corner of the outer side surface of the movable frame near the inner guide rod. The through hole matches the movable frame. The movable frame slides up and down along the opening direction of the through hole. The up and down sliding is achieved by the extension and retraction of the fine-tuning hydraulic rod. The positioning block is connected to the four sides of the outer surface of the positioning block. The limit block is used to cooperate with the positioning block to limit the maximum distance of upward movement of the movable frame.

[0018] This invention also includes a method for using a high-precision multi-point synchronous hydraulic jacking system, the method of use including the following:

[0019] In use, the operation of several hydraulic jacking systems is controlled by a point-position monitoring controller. The point-position monitoring controller controls the main hydraulic rod to lift the jacking frame simultaneously. After the jacking plate contacts the lower end of the object being lifted, the pressure sensor displays the pressure value to the point-position monitoring controller. Based on the pressure value, the point-position monitoring controller determines which of the hydraulic jacking systems has insufficient lifting pressure. When the lifting pressure is insufficient, the point-position monitoring controller controls the fine-tuning hydraulic rod in that hydraulic jacking system to lift, causing the jacking plate to move upward again to compensate for the lifting force missing in the first lift. This process continues until the lifting force of each hydraulic jacking system is equal, thus completing a high-precision, multi-point, accurate, and synchronous jacking.

[0020] The working principle and beneficial effects of this invention are as follows:

[0021] This invention, through the function of fine-tuning structure, can quickly compensate for insufficient lifting force in the hydraulic lifting system during the lifting process, thereby achieving synchronous and precise lifting at multiple points. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1-4As shown, this embodiment proposes a high-precision multi-point synchronous hydraulic jacking system, including a jacking frame 3, a point monitoring controller 1 is provided at the end of the jacking frame 3, a main hydraulic rod 2 is provided at the lower end of the jacking frame 3, a jacking plate 4 is connected to the top of the jacking frame 3, a fine adjustment structure 5 is provided between the jacking plate 4 and the jacking frame 3, a reinforcing structure 6 is provided on the outer surface of the jacking plate 4, and a pressure sensor 7 is provided in the groove opening at the upper end of the jacking plate 4.

[0035] The fine-tuning structure 5 includes a movable frame 51 that is slidably connected to the upper end of the lifting frame 3. An inner guide rod 52 is fixedly connected to the lower end of the movable frame 51. A fine-tuning hydraulic rod 53 is connected to the top end of the lifting frame 3. A positioning kit 54 is movably sleeved on the outer surface of the fine-tuning hydraulic rod 53 near the output end. A stabilizing rod 55 is fixedly connected between the positioning kit 54 and the top end of the lifting frame 3.

[0036] An anti-detachment component 8 is provided between the movable frame 51 and the lifting frame 3.

[0037] The lower end of the inner guide rod 52 is inserted into the interior of the lifting frame 3 and is slidably connected to the lifting frame 3. The length of the inner guide rod 52 is greater than the maximum extension length of the fine-tuning hydraulic rod 53. The number of stabilizing rods 55 is several sets and distributed in a ring array. The output end of the main hydraulic rod 2 is fixedly connected to the lower end of the lifting frame 3. The lifting frame 3 is pushed by the extension of the main hydraulic rod 2. The number of pressure sensors 7 is several sets and distributed in a ring array. The positioning kit 54 is kept stable with the lifting frame 3 by the stabilizing rod 55. The output end of the fine-tuning hydraulic rod 53 is fixedly connected to the lower end of the lifting plate 4. The pressure sensors 7, the lifting frame 3 and the point monitoring controller 1 are all electrically connected.

[0038] In this embodiment, when the working platform of the building construction machine needs to be lifted, the main hydraulic rod 2 is first extended by the point monitoring controller 1, so that the lifting frame 3 moves upward. At this time, the lifting plate 4 will contact the lower end of the working platform first. When the value fed back to the point monitoring controller 1 by the pressure sensors 7 on several hydraulic lifting systems is significantly less than the value of other hydraulic lifting systems, the point monitoring controller 1 immediately controls the extension of the fine-tuning hydraulic rod 53 so that the output end of the fine-tuning hydraulic rod 53 pushes the lower end of the working platform upward. At this time, the movable frame 51 will move upward, and the inner guide rod 52 will move upward to expose a part until the value of the pressure sensor 7 in this group of hydraulic lifting systems is equal to the value of the other hydraulic lifting systems, so that the pressure values ​​of each hydraulic lifting system are equal. At the same time, the positioning kit 54, the stabilizing rod 55, the movable frame 51 and the inner guide rod 52 can maintain the stability of the lifting direction.

[0039] Example 2

[0040] like Figures 5-6As shown, based on Embodiment 1, a reinforcing structure 6 is also proposed, including an extension plate 61 fixedly connected to the lower end of the lifting plate 4. A positioning post 62 is fixedly connected to the lower end of the extension plate 61. A connecting hole 63 is opened on the outer surface of the extension plate 61 corresponding to the positioning post 62. A reinforcing plate 64 is movably connected to the outer surface of the extension plate 61. A connecting post 66 is fixedly connected to the lower end of the reinforcing plate 64. An extension component 65 is provided inside the reinforcing plate 64.

[0041] The extension assembly 65 includes movable rods 651 slidably disposed on the outer surfaces of both ends of the reinforcing plate 64. A pressing column 652 is slidably disposed on the upper end of the reinforcing plate 64. The pressing column 652 and the movable rod 651 are both chamfered at their corners. A transverse groove 653 is formed inside the reinforcing plate 64 near the middle of the movable rod 651. A transverse protruding plate 654 is fixedly connected to one end of the outer surface of the movable rod 651 corresponding to the inner side of the transverse groove 653. A return spring 655 is disposed on one side of the transverse protruding plate 654 inside the transverse groove 653. A vertical groove 656 is formed inside the reinforcing plate 64 near the middle of the pressing column 652. A longitudinal protruding plate 657 is fixedly connected to the outer surface of the pressing column 652 corresponding to the inner side of the vertical groove 656.

[0042] In this embodiment, when lifting objects with a certain degree of flexibility or bending properties, it is necessary to increase the lifting area of ​​the lifting plate 4. At this time, the user can insert the connecting post 66 at the lower end of the reinforcing plate 64 downwards, corresponding to the connecting hole 63 on the outer surface of the extension plate 61, until the upper end of the reinforcing plate 64 is just flush with the upper outer surface of the lifting plate 4. At this time, the lifting area of ​​the lifting plate 4 is expanded. At the same time, during the lifting process, the pressing post 652 will contact the object being lifted first. At this time, the pressing post 652 will move downwards together with the longitudinal protruding plate 657, and the movable rod 651 will move away from the pressing post 652. This causes the movable rod 651 to move until the upper end of the pressing post 652 is flush with the outer surface of the reinforcing plate 64, thereby increasing the effective range of the reinforcing plate 64. Under the condition that the contact area with the object being lifted remains unchanged, the lifting stability is effectively enhanced, and a better support effect can be achieved.

[0043] The connecting hole 63 passes through the extension plate 61 and the positioning post 62. The diameter of the connecting post 66 is equal to the diameter of the connecting hole 63. The thickness of the reinforcing plate 64 is equal to the distance between the extension plate 61 and the upper end of the lifting plate 4. The reinforcing plate 64 increases the contact surface between the building machine's working platform and the lifting plate 4. The number of positioning posts 62 is in several groups and they are arranged in an array. The number of connecting posts 66 is equal to the number of positioning posts 62, and their positions correspond one-to-one. The number of extension components 65 is in several groups and they are arranged in an array. The movable rod 651 has an "L" shaped structure, and the upper end of one side of the movable rod 651 is flush with the upper end of the reinforcing plate 64. The movable rod 651 moves away from the pressing post 652 by pressing down on the pressing post 652. The reaction force of the return spring 655 allows the movable rod 651, together with the transverse protruding plate 654, to move towards the pressing post 652 when the pressing post 652 is not pressed down by external force.

[0044] Example 3

[0045] like Figures 7-8 As shown, based on Embodiment 2, the anti-detachment component 8 is further proposed to include an extension rod 81 fixedly connected to the outside of the lifting frame 3. A positioning block 82 is fixedly connected to the upper end of the extension rod 81. A through hole 83 is opened on the outer surface of the positioning block 82. A limiting block 84 is fixedly connected to the corner of the outer side surface of the movable frame 51 near the inner guide rod 52. The through hole 83 matches the movable frame 51. The movable frame 51 slides up and down along the opening direction of the through hole 83. The up and down sliding is achieved by the extension and retraction of the fine-tuning hydraulic rod 53. The positioning block 82 is connected to the four sides of the outer surface of the positioning block 82. The limiting block 84 is used to cooperate with the positioning block 82 to limit the maximum distance of upward movement of the movable frame 51.

[0046] This embodiment can effectively enhance the stability during the lifting process and prevent the movable frame 51 from falling off the lifting frame 3.

[0047] This invention also includes a method for using a high-precision multi-point synchronous hydraulic jacking system, the method of use including the following:

[0048] In use, the operation of several hydraulic jacking systems is controlled by the point monitoring controller 1. The point monitoring controller 1 controls the main hydraulic rod 2 to lift the jacking frame 3 simultaneously. After the jacking plate 4 contacts the lower end of the object being lifted, the pressure sensor 7 displays the pressure value to the point monitoring controller 1. The point monitoring controller 1 determines which of the several hydraulic jacking systems has insufficient lifting pressure based on the pressure value. When the lifting pressure is insufficient, the point monitoring controller 1 controls the fine-tuning hydraulic rod 53 in that hydraulic jacking system to lift, so that the jacking plate 4 moves upward again to compensate for the lifting force missing in the first lifting. This process continues until the lifting force of each hydraulic jacking system is equal, thus completing the high-precision, multi-point, accurate, and synchronous jacking.

[0049] It should be noted that the pressure values ​​of the pressure sensor 7 in the above-mentioned hydraulic jacking system are equal when the hydraulic jacking system evenly distributes the jacking load. For jacking loads of different weights, it is necessary to calculate or measure the pressure values ​​of each area before performing the jacking operation. In this state, the jacking status of each hydraulic jacking system can be determined by comparing the calculated pressure values.

[0050] It should be noted that during use, the main hydraulic rod 2 is fixed to the building or other foundation stability through the bracket, thereby maintaining the lifting performance of the main hydraulic rod 2 on the lifting frame 3.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
