Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a formwork hoisting device. Background Technology

[0002] Suspended formwork refers to formwork that is not supported from below and is directly suspended in the air. It is commonly used in bridge construction. During bridge construction, in order to meet the needs of segmented construction, wet joints need to be reserved for different construction segments. Suspended formwork is usually set at the wet joints and used as a molding template for concrete pouring.

[0003] Traditional formwork hoisting usually involves construction workers standing at the wet joint and dragging the formwork, which is labor-intensive. Furthermore, it is difficult for construction workers to ensure that the position of the formwork remains unchanged during the pouring process. The ease of installation and positional accuracy of the formwork are poor, which also reduces the quality of the structure after pouring.

[0004] Therefore, there is an urgent need to propose a formwork hoisting device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a formwork hoisting device that can improve the installation quality and accuracy of formwork, and reduce the difficulty of formwork hoisting and the labor intensity of workers.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a hoisting device for a formwork, comprising:

[0008] A support base includes a mounting frame and at least two legs, the at least two legs being spaced apart circumferentially below the mounting frame and fixedly connected to the mounting frame to support the mounting frame;

[0009] The hoisting assembly includes a roller, a flexible hoisting component, and a connector. The flexible hoisting component is wrapped around the outer periphery of the roller. One end of the flexible hoisting component is fixed to the roller, and the other end can be detachably connected to the hoisting mold. The connector is installed through the roller along its axis. Both ends of the connector are rotatably connected to the mounting frame. Rotating the connector can drive the roller to rotate around its own axis relative to the mounting frame, thereby driving the flexible hoisting component to hoist the hoisting mold.

[0010] It has at least two wheels, with a wheel located under each outrigger.

[0011] Preferably, the hoisting device further includes a locking component. The mounting frame includes a mounting frame and two mounting ear plates fixedly disposed on the top surface of the mounting frame. At least two legs are fixedly connected to the mounting frame. The two ends of the connector correspond one-to-one with the mounting ear plates and are rotatably engaged. The locking component is movably connected to the mounting ear plates. The locking component is configured to lock the connector and the mounting ear plates.

[0012] Specifically, the locking element is slidably connected or hinged to the mounting ear plate.

[0013] Optionally, an operating handle is provided on the side of the connector away from the roller, and rotating the operating handle can drive the connector to rotate.

[0014] Specifically, the operating handle is Z-shaped.

[0015] For example, the side of the operating handle away from the connector is fitted with an anti-slip sleeve or machined with anti-slip threads.

[0016] Specifically, a limiting groove is provided on the outer periphery of the roller, and the flexible lifting component is at least partially engaged with the limiting groove.

[0017] Optionally, the support base also includes support reinforcement components, with support reinforcement components provided between each pair of adjacent legs.

[0018] Optionally, the hoisting device also includes two limiting baffles, which are spaced apart along the axial direction of the rollers and located on both sides of the flexible hoisting component.

[0019] Optionally, at least two of the wheels are swivel wheels equipped with locking mechanisms.

[0020] The beneficial effects of this utility model are:

[0021] This invention proposes a formwork hoisting device. A flexible hoisting component is wrapped around the outer circumference of a roller, with one end fixed to the roller and the other end connected to the formwork. A connecting component is installed through the roller along its axis and rotatably connected to the mounting frame. Rotating the connecting component drives the roller to rotate, thereby enabling the flexible hoisting component to hoist or lower the formwork. The hoisting process is achieved by rotating the connecting component, reducing the operational difficulty and labor intensity of workers during hoisting, and improving the versatility of hoisting formwork at different installation heights. Compared to traditional formwork hoisting processes that require continuous manual dragging, this also improves the overall installation quality and accuracy of the formwork.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-2As shown, this embodiment provides a formwork hoisting device, including a support base 1, a hoisting assembly 2, and at least two traveling wheels 3. The support base 1 includes a mounting frame 11 and at least two legs 12. The at least two legs 12 are spaced apart along the circumference of the mounting frame 11 below the mounting frame 11 and are all fixedly connected to the mounting frame 11 to support the mounting frame 11. Each leg 12 is provided with a traveling wheel 3 below it. The hoisting assembly 2 includes a roller 21, a flexible hoisting component 22, and a connecting component 23. The flexible hoisting component 22 is wrapped around the outer circumference of the roller 21. One end of the flexible hoisting component 22 is fixed to the roller 21, and the other end can be detachably connected to the formwork. The connecting component 23 is arranged through the axis of the roller 21. Both ends of the connecting component 23 are rotatably connected to the mounting frame 11. Rotating the connecting component 23 can drive the roller 21 to rotate around its own axis relative to the mounting frame 11, so as to drive the flexible hoisting component 22 to hoist the formwork. One end of the flexible lifting component 22 can be equipped with a hook, which connects to the lifting formwork to achieve quick connection and quick disassembly. The flexible lifting component 22 can be a steel wire rope or a hemp rope, etc.

[0034] In this embodiment, the flexible lifting component 22 is arranged around the outer periphery of the roller 21, with one end fixed to the roller 21 and the other end connected to the lifting mold. The connecting component 23 is arranged through the axis of the roller 21 and rotatably connected to the mounting frame 11. Rotating the connecting component 23 can drive the roller 21 to rotate, thereby realizing the lifting or lowering of the lifting mold by the flexible lifting component 22. The lifting process of the lifting mold can be realized by the rotation of the connecting component 23, which not only reduces the difficulty of lifting the lifting mold and the labor intensity of workers during the lifting process, but also improves the versatility of lifting molds with different installation heights. Compared with the traditional lifting process of the lifting mold, which requires continuous manual dragging, it also improves the overall installation quality and installation accuracy of the lifting mold. At least two support legs 12 are arranged at intervals along the circumference of the mounting frame 11 below the mounting frame 11, and are both fixedly connected to the mounting frame 11. The provision of at least two support legs 12 can provide stable support for the lifting process of the lifting mold. Each outrigger 12 is equipped with a traveling wheel 3, which improves the mobility of the formwork hoisting device and reduces the difficulty and labor intensity of workers in handling the formwork hoisting device. At least two traveling wheels 3 can be swivel wheels with locking buckles, which not only ensures steering flexibility but also has a locking effect, thereby improving the mobility of the formwork hoisting device and the stability of the formwork hoisting operation.

[0035] Preferably, the hoisting device further includes a locking component. The mounting frame 11 includes a mounting frame 111 and two mounting ear plates 112 fixedly disposed on the top surface of the mounting frame 111. At least two support legs 12 are fixedly connected to the mounting frame 111. The two ends of the connector 23 correspond one-to-one with the mounting ear plates 112 and are rotatably engaged. The locking component is movably connected to the mounting ear plates 112 and is configured to lock the connector 23 and the mounting ear plates 112. The locking component is movably connected to the mounting ear plates 112 and can lock the connector 23 and the mounting ear plates 112, preventing the connector 23 from continuing to rotate relative to the mounting ear plates 112 after the hoisting device has been hoisted to the specified height. The locking component improves the positional installation accuracy and installation quality of the hoisting device. The mounting ear plates 112 are rotatably engaged with the connector 23, and the mounting ear plates 112 provide a rotation fulcrum for the connector 23 to ensure the flexible adjustment of the hoisting height of the hoisting device. The mounting lug 112 is fixedly connected to the mounting frame 111, and at least two support legs 12 are also fixedly connected to the mounting frame 111. The mounting frame 111 and the at least two support legs 12 can distribute the load borne by the mounting lug 112, providing stable support for the hoisting process of the formwork. It is understood that, in order to reduce the space occupied by the hoisting device, the roller 21 is at least partially located within the hollow cavity enclosed by the mounting frame 111.

[0036] For example, the mounting ear plate 112 has a mounting hole, and the connecting rod is rotatably connected to the mounting ear plate 112 through the mounting hole and at least partially protrudes from the mounting hole. In one embodiment, the locking member is slidably connected to the mounting ear plate 112, and the locking member has a locking hole. When the locking member slides in a first direction, the locking hole can engage with the portion of the connecting member 23 protruding from the mounting hole to lock the connecting member 23 and the mounting ear plate 112, restricting the roller 21 from continuing to rotate around its own axis and improving the installation accuracy of the hoisting operation. When the locking member slides in a second direction opposite to the first direction, the connecting member 23 can continue to rotate, realizing flexible adjustment of the hoisting position. In another embodiment, the locking member is hinged to the mounting ear plate 112, and the locking member has a locking hole. When the locking member rotates clockwise, the locking hole can engage with the portion of the connecting member 23 protruding from the mounting hole to lock the connecting member 23 and the mounting ear plate 112. When the locking member rotates counterclockwise, the connecting member 23 can continue to rotate relative to the mounting ear plate 112.

[0037] Preferably, such as Figure 1 As shown, a limiting groove 211 is formed on the outer periphery of the roller 21, and the flexible lifting component 22 is at least partially engaged with the limiting groove 211. The limiting groove 211 restricts the movement of the flexible lifting component 22 along the axial direction of the roller 21 during the lowering and lifting of the lifting mold, thereby improving the installation stability of the lifting mold and ensuring its installation accuracy. In this embodiment, the limiting groove 211 is a continuous, spiral groove formed on the outer wall of the roller 21.

[0038] The hoisting device for the formwork can also include two limiting baffles 4, which are spaced apart along the axial direction of the roller 21 and located on both sides of the flexible hoisting component 22. The limiting baffles 4 restrict the movement distance of the flexible hoisting component 22 along the axial direction of the roller 21, reducing the swaying amplitude caused by the flexible hoisting component 22 during the hoisting process. Both limiting baffles 4 can be annular, respectively located near the two ends of the roller 21 along the axial direction. Alternatively, both limiting baffles 4 can be circular plates, located at both ends of the roller 21 along the axial direction. It is understood that when the two limiting baffles 4 are located at the two ends of the roller 21 along the axial direction, clearance holes are required to allow the connecting component 23 to be rotatably connected to the mounting frame 11 via these clearance holes.

[0039] The rotation of the connector 23 can be achieved by connecting it to the output shaft of the drive motor, or by manual drive. In this embodiment, an operating handle 24 is provided on the side of the connector 23 away from the roller 21. Rotating the operating handle 24 can drive the connector 23 to rotate. The operating handle 24 reduces the difficulty of manually driving the connector 23 to rotate and improves the ease of operation. Both ends of the connector 23 can be provided with operating handles 24 to meet the operational flexibility of workers in different operating spaces. The side of the operating handle 24 away from the connector 23 can be fitted with an anti-slip sleeve or machined with anti-slip threads to enhance the worker's grip on the operating handle 24, prevent accidental slippage when the worker rotates the operating handle 24, and ensure effective manual operation.

[0040] Specifically, the operating handle 24 is Z-shaped, meaning it consists of two horizontal bars of different heights and a vertical bar connecting them. The operating handle 24 can be formed by bending a plain round steel bar. The Z-shaped operating handle 24 increases the operating torque and improves the worker's force application. In this embodiment, the connecting member 23 and the operating handle 24 are integrally formed. In other embodiments, the operating handle 24 can be welded to both ends of the connecting member 23.

[0041] In this embodiment, as Figure 1 and Figure 2 As shown, the support base 1 also includes a support reinforcement 13. A support reinforcement 13 is provided between each pair of adjacent legs 12. The support reinforcement 13 further enhances the support effect of the support base 1 and ensures the hoisting stability of the formwork. The mounting frame 11, at least two legs 12, and support reinforcement 13 can all be made of steel to enhance the overall load-bearing capacity of the support base 1.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
