Description

Technical Field

[0001] The invention belongs to the field of stage construction, and relates to a hoisting system for stage engineering construction and a construction method thereof. Background Art

[0002] With the development of the national economy and the diversification of architectural design, various large-scale stage venues are becoming more and more numerous, and the requirements for construction period and building quality are becoming higher and higher. During the construction process of the entire large-scale stage venue, there are usually problems such as high construction precision requirements, great organizational difficulties and tight construction period. The stage equipment in the venue is fully functional and the workload of equipment installation is large. In order to solve the problem of tight construction period, it is usually necessary to optimize the construction process to achieve the progress goal.

[0003] The stage area in the venue has large stage machinery and many equipment, which is the key construction route. The conventional construction plan for the stage area is usually a method of construction from bottom to top, which cannot solve the problem of tight construction period of large stage venues. Therefore, it is necessary to optimize and innovate the conventional construction organization arrangement, comprehensively consider comprehensive factors such as the technical feasibility of the plan and the rationality of the construction period, and finally select the construction plan for simultaneous operation of the ground and underground stage spaces. In order to realize the installation of stage equipment in the venue within the shortest construction period, a construction platform can be set up on the ground between the ground and underground stage spaces. The construction platform can be used as a transportation channel for the ground stage space, and can also achieve the purpose of separating the ground and underground stage spaces, making the construction space relatively independent and safe, and gaining space and time for the simultaneous construction of each stage.

[0004] After the construction platform divides the stage space into above-ground and underground stage spaces, the underground stage space is closed and relatively small. It is necessary to flexibly adjust the number of construction equipment in the underground stage space, and to continuously hoist the idle construction equipment out of the underground stage space, and at the same time hoist the required equipment into the underground stage space for use. Therefore, it is hoped to design a hoisting system for stage engineering construction that can accurately control the hoisting of various underground equipment on the ground. Summary of the invention

[0005] In view of this, in order to solve the problem that the hoisting of various equipment in the underground stage space cannot be accurately controlled on the ground during the stage construction process in the above-mentioned existing venues, which affects the construction progress, the present invention provides a hoisting system for stage engineering construction and a construction method thereof.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A hoisting system for stage engineering construction, comprising:

[0008] A construction platform, the interior of which is provided with holes for lifting materials, and a lifting assembly for lifting equipment is provided directly below the construction platform;

[0009] The hoisting assembly includes two symmetrically arranged mounting seats, two symmetrically arranged connecting rods are fixedly connected to the sides of the two mounting seats close to each other, a support plate is arranged on one side of the mounting seat, and a support assembly for supporting the equipment is arranged on the top of the support plate;

[0010] A rotating shaft is fixedly connected to one side of the support plate, one end of the rotating shaft is rotatably connected to the rotating plate, a first arc-shaped groove is opened on one side of the top of the mounting seat, and a brake assembly for braking the rotating plate is arranged inside the first arc-shaped groove;

[0011] Four symmetrical winches are arranged on the top of the construction platform, with lifting ropes wound on the winches. One ends of the four lifting ropes are fixedly connected to the tops of two mounting seats respectively and are used to lift the mounting seats. Four symmetrical circular plates are arranged on the top of the construction platform, with clamping holes opened inside the circular plates, through which the lifting ropes pass, and a limiting component for limiting the lifting ropes is arranged inside the circular plates.

[0012] Furthermore, the support assembly includes a plurality of strip grooves formed on the inner wall of the bottom of the support plate, a strip block is slidably penetrated inside the strip groove, and a same side plate is fixedly connected to the top of one side of the plurality of strip blocks. By forming a plurality of strip grooves on the inner wall of the bottom of the support plate and slidingly penetrating the strip block, combined with the fixed connection of the side plate, the width of the support plate can be flexibly adjusted. This design enables the hoisting device to be adaptively adjusted according to tools of different sizes, thereby improving the versatility and flexibility of the device.

[0013] Furthermore, a rectangular groove is provided on the inner wall of the bottom of the support plate, a threaded block is fixedly connected to the bottom of the side plate, the threaded block is slidably connected to the inner wall of the rectangular groove, a threaded rod is rotatably penetrated on one side of the support plate, the threaded rod thread penetrates the threaded block, the rectangular groove on the inner wall of the bottom of the support plate is slidably connected to the threaded block, and the threaded rod thread penetrates the threaded block, so that the lateral movement of the side plate can be controlled by rotating the threaded rod, which is easy to operate and stable and reliable. This design simplifies the adjustment process and improves the adjustment accuracy.

[0014] Furthermore, the brake assembly includes two symmetrically arranged positioning grooves opened on the inner wall of the bottom of the first arc-shaped groove, the bottom of the rotating plate is fixedly connected with two symmetrically arranged positioning rods, the positioning rods are slidably connected inside the positioning grooves, the top of the mounting seat is fixedly connected with an arc-shaped top plate, the arc-shaped top plate is used to block the top of the rotating plate, the cooperation of the positioning grooves and the positioning rods, and the blocking of the rotating plate by the arc-shaped top plate ensure that the rotating shaft can maintain a stable braking state when needed. At the same time, when the support plate contacts the ground and continues to move downward, the brake can be automatically released, allowing the rotating shaft to rotate to adjust the angle of the support plate, thereby enhancing the adaptability and stability of the device.

[0015] Furthermore, a lower arc plate is fixedly connected to one side of the mounting seat, two symmetrically arranged support blocks are fixedly connected to the bottom of the lower arc plate, two symmetrically arranged clamping rods are fixedly connected to the inner wall of the bottom of the lower arc plate, a plurality of clamping slots are provided at the bottom of the rotating shaft, and the clamping rods and the clamping slots are clamped together to control the angle of the rotating shaft. The clamping design of the lower arc plate, the support block and the clamping rod and the clamping slot at the bottom of the rotating shaft realizes the precise control of the rotating shaft angle. This braking mechanism not only ensures the safety during the hoisting process, but also facilitates the angle adjustment according to the inclination degree of the tool, thereby improving the practicality and safety of the device.

[0016] Furthermore, the limiting assembly includes a plurality of second arc grooves formed on the top of the circular plate, the plurality of second arc grooves are arranged in an annular shape and are interconnected, an annular groove is formed on the outer wall of the circular plate, a connected slide groove is formed on the inner wall of one side of the second arc groove, the bottom of the slide groove is connected to the annular groove, a clamping block is slidably connected inside the second arc groove, a slider is fixedly connected to one end of the clamping block, and one end of the slider extends to the inside of the slide groove, and by forming a plurality of second arc grooves interconnected on the top of the circular plate, and combining the design of the slide groove, the slider and the clamping block, the flexible clamping and stable limiting of the lifting rope are achieved. This design can be adaptively adjusted according to the size of the lifting rope, ensuring the stability and safety of the lifting rope during the lifting process.

[0017] Furthermore, a circular ring is rotatably connected inside the annular groove, and a plurality of inclined grooves are provided inside the circular ring. A push rod is fixedly connected to the bottom of the slider, and one end of the push rod extends into the inclined groove. The inclined groove provided inside the circular ring cooperates with the push rod at the bottom of the slider, so that the slider can be driven to move horizontally by rotating the circular ring. This transmission mechanism has a compact structure and high transmission efficiency, and provides a reliable power source for adjusting the spacing between the clamping blocks.

[0018] Furthermore, the top of the construction platform is fixedly connected with two symmetrically arranged fixed blocks, and the same worm is rotatably connected between the two fixed blocks. A drive motor is fixedly connected to one side of one of the fixed blocks, and the output shaft of the drive motor rotates through the fixed block and is fixedly connected to one end of the worm. The top of the construction platform is rotatably connected with a round rod, and the outer wall of the round rod is fixedly sleeved with a worm wheel meshing with the worm. The transmission combination of the worm, worm wheel and gear, as well as the power input of the drive motor, constitutes an efficient transmission system. This design not only simplifies the operation process (the spacing between the clamping blocks can be adjusted by controlling the motor), but also improves the transmission accuracy and stability, providing strong support for hoisting operations.

[0019] Furthermore, a gear is fixedly sleeved on the outer wall of the round rod, a limiting block is fixedly connected to the top of the round rod, and a plurality of gear teeth are fixedly connected to the outer wall of the circular ring, and the gear teeth are meshed with the gear.

[0020] A construction method of a hoisting system for stage engineering construction specifically comprises the following steps:

[0021] S1. Build a stable working platform: Place corbels at the structural openings to build a balanced and stable steel frame for construction work. Lay the table base floor on the steel frame to form a closed working platform to distinguish the working areas above and below the table. Reserve hoisting holes on the platform for vertical transportation of equipment and materials, while ensuring safe isolation;

[0022] S2. Tool hoisting and mounting base adjustment: Place the tools to be hoisted on two support plates, start the winch, and hoist the mounting base and support plate (carrying tools) to the top of the construction platform using the hoisting rope. Use the connecting rod to ensure that the two mounting bases are stably connected.

[0023] S3, Adaptive size adjustment: If the size of the device needs to be adjusted to suit different tools, the threaded rod is rotated to drive the side plates to move laterally so that the two side plates move closer or farther away from each other to adapt to the size of the tool;

[0024] S4. Angle adjustment of the support plate: When it falls to the ground, the support plate touches the ground first, and the mounting seat continues to move down, triggering the unlocking mechanism (the lever moves out of the slot), releasing the brake on the rotating shaft. At this time, the rotating shaft can be rotated to drive the support plate to adjust the angle according to the inclination of the tool to enhance stability;

[0025] S5. Ensure the stability of the lifting rope: Start the drive motor, drive the clamping block to move horizontally through a series of transmission mechanisms, adjust the distance between the clamping blocks to make them tightly contact the lifting rope, and ensure the stability of the lifting rope during the lifting process.

[0026] The beneficial effects of the present invention are:

[0027] The hoisting system for stage engineering construction disclosed in the present invention has the following advantages:

[0028] 1. Improve construction efficiency and safety: By placing the corbels at the structural opening to build a balanced and stable construction steel frame, and laying the table base subfloor as a hard isolation layer for the working platform, the working space above and below the stage is effectively divided, and synchronous construction above and below the stage is achieved, which significantly improves construction efficiency. At the same time, the reserved equipment and material hoisting holes not only form a vertical transportation channel, but also achieve the effect of safety isolation, ensuring safety during the construction process.

[0029] 2. Flexible adjustment of the size of the lifting device: By rotating the threaded rod to drive the threaded block and the side plate to move horizontally, the distance between the two support plates can be flexibly adjusted to meet the lifting needs of tools of different sizes. This design enhances the versatility and flexibility of the lifting device and reduces construction delays caused by tool size mismatch.

[0030] 3. Enhanced hoisting stability: After the support plate touches the ground, by releasing the brake on the shaft and allowing it to rotate, the angle of the support plate can be adjusted according to the inclination of the tool, thereby ensuring stability during the hoisting process. This adaptive adjustment mechanism effectively prevents hoisting accidents caused by tool tilt and improves construction safety.

[0031] 4. Intelligent adjustment of the stability of the lifting rope: The driving motor drives a series of transmission mechanisms to achieve intelligent adjustment of the spacing between multiple clamping blocks, ensuring that the clamping blocks can tightly contact the lifting rope and maintain the stability of the lifting rope. This design reduces the safety hazards caused by the shaking of the lifting rope and improves the accuracy and reliability of the lifting operation.

[0032] 5. The overall structure is compact and easy to operate: The entire lifting device has a compact structure, the components are closely matched, and the operation is simple and fast. Construction workers can quickly complete the adjustment, installation and disassembly of the lifting device, which improves construction efficiency and reduces labor intensity.

The top of the construction platform (1) is rotatably connected to a round rod (38), and an outer wall of the round rod (38) is fixedly sleeved with a worm wheel (37) meshing with the worm (33).

7. A hoisting system for stage engineering construction as claimed in claim 6, characterized in that: The outer wall of the round rod (38) is fixedly sleeved with a gear (32), the top of the round rod (38) is fixedly connected to a limit block (36), and the outer wall of the circular ring (35) is fixedly connected to a plurality of gear teeth (31), and the gear teeth (31) are meshed with the gear (32).

8. A construction method of a hoisting system for stage engineering construction according to any one of claims 4 to 7, characterized in that: The specific steps include: S1. Build a stable working platform: Place corbels at the structural openings to build a balanced and stable steel frame for construction work. Lay the table base floor on the steel frame to form a closed working platform to distinguish the working areas above and below the table. Reserve hoisting holes on the platform for vertical transportation of equipment and materials, while ensuring safe isolation; S2. Tool hoisting and mounting base (7) adjustment: Place the tool to be hoisted on two support plates (11), start the winch (2), hoist the mounting base (7) and the support plate (11) to the top of the construction platform (1) via the hoisting rope (6), and ensure that the two mounting bases (7) are stably connected via the connecting rod (10); S3, adaptive size adjustment: if the size of the device needs to be adjusted to suit different tools, the threaded rod (14) is rotated to drive the side plates (16) to move laterally, so that the two side plates (16) move closer to or farther from each other to adapt to the size of the tool; S4, angle adjustment of the support plate (11): when the support plate (11) falls to the ground, the support plate (11) first contacts the ground, and the mounting seat (7) continues to move downward, triggering the unlocking mechanism, that is, the locking rod (25) moves out of the locking slot (26), releasing the brake on the rotating shaft (21), and the rotating shaft (21) can be rotated at this time, driving the support plate (11) to adjust the angle according to the inclination degree of the tool, thereby enhancing stability; S5. Ensuring the stability of the lifting rope (6): starting the driving motor (4), driving the clamping block (30) to move horizontally through a series of transmission mechanisms, and adjusting the spacing of the clamping blocks (30) so that they are in close contact with the lifting rope (6), thereby ensuring the stability of the lifting rope (6) during the lifting process.
