Description

Technical Field

[0001] This utility model belongs to the field of steel formwork installation, and in particular relates to a steel formwork installation device for concrete structures. Background Technology

[0002] In my country's municipal construction projects, there is a significant amount of work involving the construction or repair of concrete structures. However, current technologies for steel formwork support installation are limited by the weight and irregular shape of the steel formwork, making manual installation impossible. Generally, a combination of manual labor and cranes is used. But using cranes presents challenges: high rental costs, highly skilled operators, large and inflexible equipment, numerous safety hazards, and strict requirements for the work surface. For example, in narrow work areas, where the crane's load-bearing capacity is insufficient (risk of tipping over), or on uneven surfaces, the crane cannot be used.

[0003] Comparing with Chinese Patent CN222433979U, an auxiliary lifting device for forklifts is disclosed, including a base with a rotating block rotatably connected to the top of the base. A hydraulic rod is fixedly installed on one side of the rotating block. By activating a first motor to drive a winding wheel to rotate, the pull rope is wound up, causing the pull rope to pull the hook upward at the bottom of the connecting plate, thereby causing the goods to slide off the hook. This allows for automatic disengagement of the forklift lifting device from the goods, facilitating practical operation. By inserting the forklift's forks into the fork slots, the forks can directly drive the lifting device to move. Simultaneously, rotating a bidirectional screw engages with the threaded sleeves on both sides, causing them to drive two insert plates to adjust according to the spacing of the forklift's forks. This facilitates quick installation of the forklift lifting device onto forklifts with different fork spacing, improving practicality.

[0004] However, the aforementioned patents are prone to causing rotation and swaying when lifting long, plate-shaped objects such as steel formwork, which seriously affects the stability of movement and installation and greatly reduces the efficiency of steel formwork installation for concrete structures. Therefore, a new type of equipment needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete structure steel formwork installation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete structure steel formwork installation device includes a lifting assembly for connecting a forklift to lift the steel formwork, and an adjustment assembly at the top of the lifting assembly for pulling and adjusting the lifting height. Two stabilizing assemblies for telescopically pushing auxiliary supports of the steel formwork are symmetrically arranged on both sides of the lifting assembly. The lifting assembly includes a frame body with two symmetrically arranged connecting sleeves at the bottom. An extended cantilever is provided in the middle of the frame body, with its bottom end rotatably connected to the frame body via a pivot. A hook is rotatably mounted on the top of the extended cantilever, and a lifting ring is fixedly provided near the hook at the top of the extended cantilever.

[0008] The adjustment assembly includes a sub-frame, on which a limit guide wheel is rotatably mounted. A winding wheel is provided on one side of the limit guide wheel, and a steel cable is wound on the winding wheel. The top end of the steel cable is tied to the lifting ring, and a control mechanism is provided at both ends of the winding wheel.

[0009] The stabilizing component includes a fixed frame, a limiting rod slidably mounted in the middle of the fixed frame, a limiting head mounted at the end of the limiting rod, and a locking pin mounted on the fixed frame.

[0010] Furthermore: the main body of the frame includes a base plate, on which two upright plates are symmetrically arranged, and a limit rod is provided between the upright plates.

[0011] Furthermore: the upright plate and the base plate are arranged perpendicularly, and the base plate, the upright plate, and the connecting sleeve are welded together.

[0012] Furthermore: the control mechanism includes a hand crank at one end of the winding wheel, a ratchet at the end of the winding wheel away from the hand crank, a backstop plate on one side of the ratchet plate, and the backstop plate and the auxiliary frame are rotatably connected.

[0013] Furthermore: the winding wheel is a horizontally arranged cylindrical shape, and the limiting guide wheel is higher than the winding wheel.

[0014] Furthermore, the limiting head is spherical and made of natural rubber.

[0015] Furthermore: the limiting rod is cylindrical, and the limiting head and the limiting rod are riveted together.

[0016] Compared with existing technologies, the beneficial effects are:

[0017] 1. The adjustable limit heads on both sides form a triangular support with the hook, which effectively prevents the steel formwork from swaying or tilting during movement, reduces the risk of falling off, and enhances operational safety; the connecting sleeve can be directly used with a forklift, which simplifies the complex process of traditional hoisting equipment, enables rapid movement and positioning, and significantly improves construction efficiency.

[0018] 2. Through mechanical structural innovation, the problems of inaccurate positioning, poor stability, and low efficiency in traditional steel formwork installation have been solved. It combines safety, economy, and ease of use, and is suitable for concrete construction scenarios such as buildings and bridges.

[0019] 3. The sliding limit rod, in conjunction with the rubber limit head, adapts to the lateral pushing requirements of steel formwork of different sizes. After the locking nail is fixed, a flexible contact is formed, which protects the formwork surface and enhances stability. The integrated hoisting and adjustment functions eliminate the need for additional cranes or manual support, reducing equipment investment and labor costs. The hoisting and installation are completed in one integrated process, shortening the construction period. It is especially suitable for repetitive formwork installation projects.

[0020] 4. The hand-cranked winding wheel with a ratchet-anti-reverse mechanism allows for fine-tuning of the steel formwork lifting height, ensuring the slings are taut and precisely positioned, avoiding the uncertainty of manual pulling; the steel cable smoothly transmits tension through a high-position guide wheel, reducing friction loss, while the limit rod fixes the initial position of the cantilever, making operation more labor-saving and controllable; the combination of ratchet and anti-reverse plate prevents the winding wheel from accidentally loosening, ensuring the steel cable remains taut and preventing uncontrolled load.

Two stabilizing assemblies for telescopically pushing auxiliary supports of the steel formwork are symmetrically arranged on both sides of the lifting assembly.

[0030] In this embodiment: the hoisting assembly includes a frame body, with two connecting sleeves 102 symmetrically arranged at the bottom of the frame body, an extended cantilever 106 arranged in the middle of the frame body, the bottom end of the extended cantilever 106 being rotatably connected to the frame body via a rotating shaft 104, a hook 108 being rotatably installed at the top of the extended cantilever 106, and a lifting ring 107 being fixedly arranged at the top of the extended cantilever 106 near the hook 108; the frame body includes a base plate 101, with two upright plates 103 symmetrically arranged on the base plate 101, and a limit rod 105 arranged between the upright plates 103; the upright plates 103 and The base plate 101 is vertically set, and the base plate 101, the upright plate 103 and the connecting sleeve 102 are welded together. First, drive the forklift to lift the main body of the frame and move it to the steel template through the connecting sleeve 102. Then, hang the sling at the top of the steel template on the hook 108 of the extended cantilever 106. The steel cable 204 pulls the extended cantilever 106 through the lifting ring 107 to lift the hook 108 under the support of the pivot 104 (the base plate 101 supports the pivot 104 to rotate through the upright plate 103, and the limit rod 105 is used to limit the extended cantilever 106 in the relaxed state of the support) until the sling is taut.

[0031] In this embodiment: the adjustment component includes a sub-frame 201, on which a limit guide wheel 202 is rotatably mounted. A winding wheel 203 is provided on one side of the limit guide wheel 202, and a steel cable 204 is wound on the winding wheel 203. The top end of the steel cable 204 is tied to a lifting ring 107. Control mechanisms are provided at both ends of the winding wheel 203. The control mechanism includes a hand crank 205 provided at one end of the winding wheel 203, and a ratchet 206 provided at the end of the winding wheel 203 away from the hand crank 205. A backstop plate 207 is provided on one side of the ratchet 206 to prevent backflow. The reverse plate 207 and the sub-frame 201 are rotatably connected; the winding wheel 203 is a horizontally set cylindrical shape, and the limiting guide wheel 202 is higher than the winding wheel 203; the winding wheel 203 is rotated by the hand crank 205 under the support of the sub-frame 201, and under the guidance of the limiting guide wheel 202, the winding steel cable 204 is pulled by the lifting ring 107 to pull the extended cantilever 106 and lift the hook 108 under the support of the rotating shaft 104. At the same time, the anti-reverse plate 207 locks the ratchet 206 to prevent the winding wheel 203 from reversing and releasing the steel cable 204, thus ensuring that the steel cable 204 is taut.

[0032] In this embodiment: the stabilizing component includes a fixed frame 301, a limiting rod 302 is slidably installed in the middle of the fixed frame 301, a limiting head 303 is installed at the end of the limiting rod 302, and a locking pin 304 is installed on the fixed frame 301; the limiting head 303 is spherical and made of natural rubber; the limiting rod 302 is cylindrical, and the limiting head 303 and the limiting rod 302 are riveted together; the limiting rod 302 slides under the support of the fixed frame 301, so that the limiting head 303 pushes the steel template from both sides for stabilization, and the locking pin 304 is tightened to fix it, so that the two limiting heads 303 and the hook 108 form a three-point support, ensuring the stability of the movement and installation of the steel template.

[0033] Working principle: First, the forklift is used to lift the main frame of the machine and move it to the steel formwork via the connecting sleeve 102. Then, the sling at the top of the steel formwork is hung on the hook 108 of the extended cantilever 106. Then, the winding wheel 203 is rotated by the hand crank 205 with the support of the auxiliary frame 201. Under the guidance of the limit guide wheel 202, the winding steel cable 204 is pulled by the lifting ring 107 to lift the hook 108 of the extended cantilever 106 with the support of the rotating shaft 104 (the base plate 101 supports the rotation of the rotating shaft 104 through the upright plate 103, and the limit rod 105 is used to limit the extension cantilever 106 in the relaxed state of the support) until the sling is taut. At the same time, the anti-reverse mechanism is activated. Plate 207 jams ratchet 206, preventing winding wheel 203 from reversing and releasing steel cable 204, ensuring steel cable 204 is taut. Then, the forklift is started to support the main frame and raise it, so that the extended cantilever 106 pulls the sling through hook 108 to lift the steel formwork and detach it from the ground. Then, under the support of fixed frame 301, the sliding limit rod 302 is slid, so that the limit head 303 pushes the steel formwork from both sides to stabilize it, and the locking nail 304 is tightened to fix it, so that the two limit heads 303 and hook 108 form a three-point support, ensuring the stability of the movement and installation of the steel formwork. Finally, the forklift is driven to move the steel formwork to the installation position for installation.
