Description

Technical Field

[0001] The present invention relates to the technical field of building construction and maintenance equipment, and in particular to a factory building concrete support beam and column reinforcement device and a construction method thereof. Background Art

[0002] In the maintenance, functional transformation or seismic reinforcement of existing buildings, it is common to reinforce key concrete support beams, columns and other load-bearing components. According to the current building seismic assessment and reinforcement standards, direct reinforcement of components is the main method to improve the bearing capacity of the structure. Before implementing reinforcement schemes such as increasing the cross-section method and the external steel method, it is usually necessary to temporarily support the components to unload or ensure construction safety. However, existing temporary support technical solutions generally have significant defects: On the one hand, the traditional support system, consisting of scaffolding and multiple separate jacks, is bulky, requires numerous components, and is time-consuming and labor-intensive to set up and dismantle on site. This is especially difficult to move and deploy within existing factory buildings, where equipment is densely packed and space is limited, severely impacting construction efficiency.

[0003] On the other hand, some existing mechanical support devices, although relatively integrated in structure, often have poor mobility, heavy weight, and are difficult to flexibly enter the interior of the factory; more importantly, their height adjustment function usually relies on manual handles or wrenches, which are not only slow to adjust and labor-intensive, but also have a limited adjustment range. It is difficult to efficiently and accurately adapt to the height of beams in different projects and locations, resulting in poor versatility of the equipment and greatly limited scope of application. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a plant building concrete support beam reinforcement device and a construction method thereof.

[0005] The specific technical solutions are as follows: A plant building concrete support beam reinforcement device, comprising a base configured with a moving mechanism; At least two sets of symmetrically arranged lifting mechanisms, each of which is vertically mounted on the base, and each set of lifting mechanisms includes a fixed support column and a movable column that can slide vertically within the support column; a protective plate connected to the top of the movable cylinder of the at least two sets of lifting mechanisms; and A driving system for synchronously driving the at least two lifting mechanisms to perform lifting, wherein the driving system is installed on the base.

[0006] Optionally, the drive system includes: a drive motor that provides rotational power; a worm gear drivingly connected to the output end of the drive motor; and A worm wheel meshes with the worm and has a reverse self-locking feature.

[0007] Optionally, the drive system further includes a linkage mechanism, which is used to synchronously distribute the rotational motion of the worm gear to the at least two lifting mechanisms.

[0008] Optionally, the linkage mechanism includes: a connecting rod fixed coaxially with the worm gear and rotating therewith; at least two first bevel gears fixed to the connecting rod; and At least two second bevel gears are respectively engaged with the first bevel gears, and each of the second bevel gears drives a corresponding lifting mechanism.

[0009] Optionally, each lifting mechanism is provided with an adjustment mechanism, and the adjustment mechanism includes: an adjusting screw coaxially connected to the second bevel gear and rotating therewith, the adjusting screw being accommodated in the interior of the movable cylinder; and An adjusting nut is threadably sleeved on the adjusting screw and fixed to the inner wall of the movable cylinder.

[0010] Optionally, a limiting sliding groove for guiding is provided on the inner wall of the supporting cylinder, and a limiting sliding block that slides in cooperation with the limiting sliding groove is provided on the outer wall of the movable cylinder.

[0011] Optionally, a plurality of universal wheels are installed at the bottom of the base, and the base is also provided with a locking mechanism for lifting the base from the ground and locking it during operation.

[0012] Optionally, the locking mechanism is one or more sets of hydraulic leveling legs.

[0013] A construction method for reinforcing a concrete support beam column of a factory building comprises the following steps: Moving into position step: using the moving mechanism to move the reinforcement device to the bottom of the beam or column to be reinforced; Locking and leveling step: activating the locking mechanism to firmly support the base on the ground; Lifting support step: start the driving system to drive the movable cylinder of the lifting mechanism to rise synchronously until the protective plate is pressed against the beam or column to be reinforced.

[0014] Optionally, in the lifting support step, when the drive system stops working, the drive system uses the self-locking characteristics of the worm gear and worm mechanism to automatically lock the protective plate at the current support height without the need for external braking.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By integrating universal wheels with a locking mechanism into the base, this invention cleverly achieves rapid switching between the equipment's "transport mode" and "operation mode," providing flexibility during transport and stability and reliability during operation. Combined with a long-travel sleeve-type lifting mechanism, it offers a wide vertical adjustment range, easily adapting to factory beams of varying heights. This resolves the core contradiction between mobility and applicability of traditional equipment, significantly improving its versatility and field deployment efficiency. This invention innovatively utilizes a worm gear drive as its core power conversion unit. This not only achieves smooth, high-torque output at a high transmission ratio, providing ample power for lifting heavy objects, but also, crucially, fully utilizes its inherent reverse self-locking feature. This means that in the event of a power outage or motor stop, the lifting mechanism instantly and automatically locks into position, effectively preventing accidental sliding due to gravity. This eliminates the need for any additional, potentially ineffective braking systems, ensuring absolute stability and safety during the mechanical support process. The entire process is driven by a motor, enabling one-touch electric lifting, significantly reducing labor intensity and increasing operational efficiency by several times compared to manual operation. The specially designed bevel gear linkage mechanism ensures that multiple lifting mechanisms are driven by a single power source in the simplest way, achieving absolute synchronous lifting. This ensures that the top guard plate remains level throughout the entire lifting process, avoiding major safety risks such as overloading and overturning that could result from asynchronous lifting.

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0021] The present invention provides a plant concrete support beam reinforcement device, referring to Figures 1-4 ,include: A base 1 equipped with a moving mechanism; At least two sets of symmetrically arranged lifting mechanisms, the lifting mechanisms are vertically installed on the base 1, and each set of lifting mechanisms includes a fixed support column 21 and a movable column 22 that can slide vertically inside the support column 21; A protective plate 3 connected to the top of the movable cylinder 22 of at least two sets of lifting mechanisms; and A driving system for synchronously driving at least two lifting mechanisms to perform lifting, and the driving system is installed on the base 1.

[0022] The base 1 serves as the supporting platform and framework for the entire device. Multiple heavy-duty universal wheels mounted on the bottom of the mobile mechanism allow operators to easily push it across flat ground, freely maneuvering between the device and the columns, and precisely maneuvering it to any designated support point. This improves efficiency by several orders of magnitude compared to traditional scaffolding, which requires piecemeal transport and on-site erection. This device is equipped with at least two completely symmetrical lifting mechanisms, ensuring that the supporting force is evenly applied to the supported structure, effectively avoiding eccentric moments. Any eccentric load could induce unexpected bending or torsional stresses in the fragile structure being reinforced, leading to new damage. The symmetrical design eliminates this risk at the source, ensuring an absolutely smooth and safe support process. The top guard plate 3 is the interface between the device and the concrete beams and columns being reinforced. Its function goes far beyond transmitting supporting forces. Designed as a large flat plate, the top guard plate 3 effectively distributes and transmits pressure, avoiding stress concentration and maximizing surface protection for the reinforced structure, preventing indentations, cracking, or surface spalling caused by excessive localized pressure. The synchronous drive system is the power source for all movements. It is responsible for accurately driving all lifting mechanisms to move in complete synchronization and is the key to achieving high-precision support.

[0023] Specifically, the drive system includes: a drive motor 41 for providing rotational power; A worm 42 drivingly connected to the output end of the drive motor 41; and A worm wheel 43 meshes with the worm 42 and has a reverse self-locking feature.

[0024] The drive system is integrated and installed inside the working chamber 5 set on the upper part of the base 1 to protect it from the influence of the external environment. The drive motor 41 is installed on the outer wall of the rear side of the base 11. The driving end of the drive motor 41 is fixed with a rotating shaft. The end of the rotating shaft away from the drive motor 41 rotates and extends into the interior of the working chamber 55. The worm 42 is fixed to the end of the rotating shaft. The end of the worm 42 away from the rotating shaft is connected to the bearing on the front inner wall of the working chamber 5. The worm gear 43 is connected to the bottom of the worm 42 and is located inside the working chamber 55. When the drive motor 41 is running, its rotational motion is transmitted to the worm gear 43 through the worm 42, achieving a significant reduction in speed and a significant increase in torque. Due to the self-locking characteristics of the worm gear 43 and worm 42 transmission, when the motor stops, even if the worm gear 43 is subjected to a huge reverse torque, it cannot reverse drive the worm 42, thereby achieving reliable self-locking. In a worm gear 43 and worm 42 transmission, power is typically transmitted from the worm 42 to the worm gear 43. However, since the helix angle of the worm 42 is typically very small, when the worm 42 stops rotating, the reverse force from the worm gear 43 (which is currently bearing the immense weight of the entire supported structure above) generates a significant friction torque. This friction torque is far greater than the torque attempting to drive the worm 42 to rotate. Therefore, the worm gear 43 cannot reversely drive the worm 42 to rotate.

[0025] The drive system further includes a linkage mechanism 6, which is used to synchronously distribute the rotational motion of the worm gear 43 to at least two lifting mechanisms. The linkage mechanism 6 includes: a connecting rod 61 fixed coaxially with the worm gear 43 and rotating therewith; At least two first bevel gears 62 fixed to the connecting rod 61; and At least two second bevel gears 63 are respectively engaged with the first bevel gear 62 , and each second bevel gear 63 drives a corresponding lifting mechanism.

[0026] The linkage mechanism 6 distributes the power output by the worm gear 43. A connecting rod 61 rigidly passes through the center hole of the worm gear 43, rotating synchronously with it. Two first bevel gears 62 are symmetrically fixed and sleeved on the left and right outer walls of the connecting rod 61. These first bevel gears 62 mesh with two independent sets of second bevel gears 63, respectively. When the connecting rod 61 rotates, the two first bevel gears 62 drive the two second bevel gears 63 to rotate synchronously in opposite directions, thereby splitting the power and transmitting it to the lifting mechanisms on both sides.

[0027] Each lifting mechanism is provided with an adjusting mechanism 7, which includes: an adjusting screw 71 coaxially connected to the second bevel gear 63 and rotating therewith, the adjusting screw 71 being accommodated in the interior of the movable cylinder 22; and An adjusting nut 72 is threadedly sleeved on the adjusting screw 71 and fixed to the inner wall of the movable cylinder 22.

[0028] The adjustment mechanism 7 is the executive unit that realizes the final lifting and lowering. The center of each second bevel gear 63 is fixedly connected to an adjustment screw 71, so that it rotates synchronously with it. The outer surface of the adjustment screw 71 is processed with a trapezoidal or rectangular thread, and an adjustment nut 72 is threaded on it. The outer part of the adjustment nut 72 is fixedly connected to the bottom inner wall of the movable cylinder 22. A limiting groove for guidance is provided on the inner wall of the support cylinder 21, and a limiting slider that slides with the limiting groove is provided on the outer wall of the movable cylinder 22. Since the movable cylinder 22 is constrained by the guidance of the limiting groove and the limiting slider inside the support cylinder 21 and cannot rotate, when the adjustment screw 71 rotates, the adjustment nut 72 can only make vertical linear movement along the axis of the adjustment screw 71. The vertical movement of the adjusting nut 72 directly drives the movable column 22 connected to it to perform smooth vertical lifting and lowering inside the supporting column 21. Since the lifting mechanisms on both sides are driven by the same drive and linkage system, their lifting actions are completely synchronized, thereby ensuring that the protective plate 3 fixed on the top of all movable columns 22 can always remain horizontal and be lifted or lowered smoothly until it is tight against the target beam and exerts uniform supporting force.

[0029] A plurality of universal wheels are installed at the bottom of the base 1, and a locking mechanism is also provided on the base 1 for lifting and locking the base 1 from the ground during operation. When the device reaches the predetermined position, its working state needs to be seamlessly switched from "moving" to "stable", and the locking mechanism is a set or multiple sets of hydraulic leveling legs. After starting, the hydraulic legs will extend downward to lift the entire base 1 from the universal wheels so that the chassis of the legs are in direct contact with the ground. This not only transfers the weight of the equipment firmly to the ground, but also completely eliminates any potential instability caused by the rolling and turning of the universal wheels. In this embodiment, the four corners are hydraulic leveling legs. After reaching the predetermined working position, the hydraulic system is started, and the legs are extended to lift the base 1 steadily, so that the universal wheels are off the ground, thereby firmly locking the equipment in the working position and providing a rigid support foundation.

[0030] The present invention uses universal wheels to maneuver the entire device to the bottom of a predetermined reinforcement point within the factory building. Next, the hydraulic outriggers are activated to lock and level the device. Finally, the control box activates the drive motor 41. The powerful force, flowing through a complete transmission chain, ultimately drives the guard plate 3 precisely and smoothly to the predetermined height. The self-locking properties of the worm gear 43 and worm 42 provide long-term, reliable support. The entire process is efficient, labor-saving, and inherently safe.

[0031] The present invention provides a method for reinforcing a concrete support beam and column reinforcement device for a factory building, comprising the following steps: Moving into position step: Before the operation begins, the operator uses a portable control unit (such as an industrial remote control handle) to control the universal wheels at the bottom of the device and use the moving mechanism to move the reinforcement device to the bottom of the beam or column to be reinforced; Locking and leveling steps: After the device is in place, the operator starts the "locking and leveling" program on the control unit; at this time, the hydraulic system is activated, and four or more leveling legs are synchronously extended downward, steadily lifting the entire base 1 from the universal wheels and firmly supporting it on the ground; Lifting and supporting steps: After confirming that the base 1 is locked and leveled, the operator starts the main drive system, and the drive motor 41 starts to run. Through the worm gear 43, worm 42 and mechanical linkage mechanism 6, the movable cylinders 22 of all lifting mechanisms are driven to climb upward at a completely synchronized speed and smoothly. The operator can monitor the lifting height or supporting force in real time until the protective plate 3 is pressed against the beam or column to be reinforced; During the lifting support step, when the drive system stops working, the drive system utilizes the self-locking characteristics of the worm gear 43 and the worm 42 mechanism. Once the motor stops, the reverse self-locking characteristics of the worm gear mechanism take effect immediately, and the entire lifting system is instantly and firmly locked at the current height and support force state without any additional operation.

[0032] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
