Description

Technical Field

[0001] This utility model belongs to the field of industrial building technology and relates to a steel structure factory building with an electrically folding roof. Background Technology

[0002] In today's era of rapid industrial development, the demand for production space in various industrial settings is becoming increasingly diversified and complex. However, the widely used steel structure factory buildings currently face numerous technical bottlenecks, severely restricting the efficiency and flexibility of industrial production. Among these, the most prominent problems are spatial rigidity and limited functionality. At the same time, traditional sliding steel structure factory buildings consume a large amount of manpower and resources. These problems urgently need to be solved.

[0003] From a space utilization perspective, existing steel structure factory buildings suffer from significant spatial rigidity defects. These buildings are often designed and constructed with fixed structural layouts, strictly dividing the internal space and making flexible adjustments difficult to meet the actual needs of different industrial scenarios. For example, in production line scenarios requiring frequent movement and rearrangement of large equipment, the fixed column spacing and span of traditional steel structure factory buildings become insurmountable obstacles. Large equipment cannot smoothly enter designated locations, or even if it manages to enter, the unreasonable spatial layout will obstruct the production process, significantly reducing production efficiency. Furthermore, for companies that need to temporarily add production areas or adjust production line layouts, the fixed spatial structure of traditional steel structure factory buildings makes renovation work extremely difficult, requiring significant time and money and potentially impacting normal production operations.

[0004] A major drawback of existing steel structure workshops is their limited functionality. Many steel structure workshops are designed with only basic production functions in mind, lacking comprehensive consideration for other auxiliary functions. For example, in some industrial production processes with high environmental requirements, such as electronics manufacturing and precision instrument processing, workshops need to have excellent temperature and humidity control and air purification capabilities. However, traditional steel structure workshops often cannot meet these special needs, leading to a decline in product quality. Furthermore, as industrial production demands increasingly higher levels of safety and environmental protection, existing steel structure workshops also have many shortcomings in terms of fire protection facilities and waste disposal, making them ill-suited to the development trends of modern industry.

[0005] Besides the issues of fixed space and limited functionality, traditional sliding steel structure factory buildings also suffer from significant drawbacks, such as high manpower and material costs. Opening and closing sliding doors typically requires manual operation, which is not only inefficient but also demands substantial human resources. Manual operation of sliding doors also poses safety hazards in inclement weather. Furthermore, the complex mechanical structure of sliding doors makes them prone to malfunctions, resulting in high maintenance and repair costs. Moreover, the poor sealing performance of sliding doors can lead to large fluctuations in temperature and humidity inside the factory, increasing energy consumption and production costs.

[0006] In summary, existing steel structure factory buildings suffer from numerous problems in space utilization, functional design, and operation and maintenance, which have seriously affected the efficiency and quality of industrial production. To adapt to the development needs of modern industry, it is essential to increase research and innovation efforts in steel structure factory building technology, break through the limitations of fixed space and single function, reduce the consumption of human and material resources, and create more flexible, efficient, and intelligent industrial production spaces.

[0040] Example 1

[0041] Please see Figures 1-6 This is a steel structure factory building with an electrically folding roof, including double rows of columns, with diagonal supports and transverse connectors between adjacent columns to form a three-dimensional truss structure, which improves the wind pressure resistance and seismic performance of the track system.

[0042] Each row of columns has a pre-drilled track installation interface at its top. The sliding track is connected to the track installation interface via shear bolts. The movable roof module 1 is sequentially connected to the high-precision sliding track via a four-bar linkage 8 and a guide wheel assembly 7. The guide wheel assembly 7 rolls in contact with the sliding track. The sliding track is made of high-strength steel, with a hardened surface and fitted with low-friction grooves. The four-bar linkage 8 includes adjustable-length links to compensate for errors during track installation and to ensure that the lateral offset is controlled within a certain error range when the roof moves along the preset trajectory.

[0043] At least one end of the double-row columns is equipped with a fixed roof 6, which is rigidly connected to the columns to form the main structure 10 of the steel structure factory building. A storage rack 3 is located below the fixed roof 6. The movable roof 1 module slides to the storage rack 3, rotates and folds, and is stored on the storage rack 3, completely hidden beneath the fixed roof 6. A longitudinal folding function is added to the lateral sliding function to maximize the factory building's clearance.

[0044] The storage rack 3 is equipped with temporary limiting blocks to facilitate positioning and fixing of the movable roof module. This prevents the movable roof from sliding further or shifting due to inertia or other external forces after reaching the storage rack. It also provides some protection for the movable roof, preventing damage from collisions between adjacent movable roofs. The fixed roof 6 integrates a solar power supply unit to power the drive system and lighting equipment.

[0045] The movable roof module 1 comprises several movable roofs 1, which are connected by hinge shafts. Each movable roof 1 is equipped with a folding motor drive unit 5, which drives the hinge shaft to rotate, thereby enabling the movable roof 1 to be folded and stored longitudinally on the storage rack 3. Adjacent movable roofs 1 are also connected by cables, which are automatically wound and unwound via an electric reel. The hinge shaft contains a worm gear self-locking mechanism, allowing the movable roof 1 to be folded synchronously by the folding motor drive unit 5.

[0046] A limiting device 9 is provided at the end of the sliding track; the limiting device 9 is electrically connected to the distance measuring sensor to realize the translation trajectory control and endpoint positioning of the movable roof 1. An adjustable connecting plate is provided at the docking point of the sliding track, and the track surface is coated with an anti-rust coating. The adjustable connecting plate can ensure smooth docking between adjacent tracks and allows for fine adjustments to adapt to different installation conditions or track deformation. By adjusting the adjustable connecting plate, the overall straightness and levelness of the track can be ensured, thereby ensuring the smooth sliding of the movable roof module on the track.

[0047] Each movable roof 1 is also equipped with a movable motor drive unit 4, which includes a synchronous motor, a reducer, and a rack and pinion transmission unit connected in sequence. The synchronous motor provides power, the reducer adjusts the speed and torque, and then drives the guide wheel group 7 through the rack and pinion transmission unit, moving the movable roof 1 on the sliding track. The synchronous motor is equipped with an intelligent protection device for emergency braking when the synchronous motor encounters abnormal resistance. Rotary motion is converted into linear motion, ultimately driving another unit. The synchronous motor is responsible for precise speed control, the reducer adjusts the torque and speed to match the load requirements, and the rack and pinion transmission unit converts the motion form to achieve linear drive. The movable motor drive unit 4 can drive the movement of the roof modules, effectively reducing manpower. The control system adopts a bus architecture integrating a multi-channel absolute encoder to monitor roof displacement in real time, supporting single-module inching, multi-module group linkage, and preset deployment mode recall. The drive system has a built-in intelligent protection mechanism that automatically triggers emergency braking when abnormal resistance or deviation is detected. Simultaneously, an electric drum cable reel achieves adaptive cable winding and unwinding during movement, eliminating the risk of cable entanglement.

[0048] The mobile motor drive unit 4 and the folding motor drive unit 5 are electrically connected to the control system to enable remote wireless control of them. The control system integrates a bus architecture, supporting single-module inching, group linkage, and preset deployment modes. The control system is operated via a wireless remote control and supports obstacle detection sensors and overload protection modules, automatically triggering an emergency stop in abnormal conditions. The detection sensors control the roof movement based on outdoor weather changes; for example, automatically folding the mobile roof 1 during rain and automatically opening it when there is an indoor gas leak.

[0049] A sealing unit is installed between adjacent movable roofs 1. The sealing unit includes a compressible rubber baffle, a drainage channel, and an elastic sealing strip. The rubber baffle is installed on the adjacent side of the movable roof 1, and the sealing strip is installed around the perimeter of the movable roof 1. At the joint of adjacent movable roofs 1, the sealing strip and the rubber baffle form a drainage channel.

[0050] Example 2

[0051] Based on Embodiment 1, the movable roof module 1 can be replaced with other roof modules with specific functions. The replacement roof module is quickly replaced via a standardized quick-installation interface on the movable roof 1, allowing for rapid functional module replacement without interrupting factory operations. The standardized quick-installation interface integrates a bidirectional guide groove, an electromagnetic latch, and a multi-level sealing system, supporting rapid replacement of various roof modules. The bidirectional guide groove guides the replacement roof module for rapid alignment and limits its movement. The electromagnetic latch then quickly locks or unlocks the module. Simultaneously, the self-sealing waterproof component provides a seal during connection, preventing water and dust from entering.

[0052] In this embodiment, the movable roof module 1 in Embodiment 1 is replaced with a rainproof roof module. The rainproof roof module includes a weather-resistant steel plate layer and a self-healing waterproof layer, with drainage channels and elastic sealing strips at the edges for drainage.
