Description

Technical Field

[0001] This utility model relates to the technical field of temporary protective facilities for building construction, specifically a telescopic double-shed heavy-duty steel rail mobile work shed for construction sites. Background Technology

[0002] In open-air construction projects, especially in stages such as rebar cage unloading, tying, and precast component processing, the work is significantly affected by weather conditions, making the need for mobile protective facilities extremely urgent. Traditional work sheds, as the primary temporary protective measure, aim to provide enclosed or semi-enclosed spaces in open-air work areas to shield against rain and snow and isolate them from the scorching sun, ensuring the continuity of construction and the working environment of workers. With the expansion of construction scale and the acceleration of construction pace, modern engineering projects place higher demands on the span, mobility, structural stability, and environmental adaptability of work sheds. Simply relying on fixed or simple mobile protective sheds is no longer sufficient to meet the needs of efficient and safe construction organization. Therefore, retractable work sheds that can move flexibly with the work surface and possess good protection and adaptability have become important temporary facilities for improving the level of mechanization and modularization on construction sites.

[0003] Although retractable work sheds have been used in engineering projects, existing technologies generally suffer from several key defects that severely restrict their efficiency and safety. First, the track systems typically use triangular iron, 18kg small ground rails, or lightweight round pipes, which have limited load-bearing capacity. For sheds up to 40m in length, track deformation, shed jamming, or even overturning are highly likely during movement, resulting in extremely poor stability. Second, the sheds are mostly designed with a single structure without consideration for size adaptability. There is no effective safety distance between sheds during expansion and contraction, making them prone to collision damage. Furthermore, the side walls are either completely enclosed, leading to poor ventilation in the work area, or completely open, failing to meet basic protection requirements such as rain and sun protection. Third, the track installation lacks standardized anchoring techniques, simply laying it on the ground. Frequent movement can cause the track to shift, resulting in low positioning accuracy and affecting construction efficiency. Fourth, the fixed expansion and contraction dimensions of the shed cannot simultaneously meet the different needs of unloading steel cages (requiring the shed to retract to create space) and providing work protection (requiring the shed to expand to cover the work area), resulting in poor adaptability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a telescopic double-shed heavy-duty steel rail mobile work shed for construction sites, which solves the problems mentioned in the background art, such as poor stability, susceptibility to collision damage, difficulty in balancing ventilation and protection, low positioning accuracy, and low work efficiency caused by insufficient track load-bearing capacity, unreasonable shed design, unstable track installation, and poor telescopic adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic double-shed heavy-duty steel rail mobile work shed for construction sites, comprising a large shed body, a small shed body, a base structure, and a mobile module.

[0007] Preferably, the concrete strip foundation has a steel reinforcement cage inside, and the anchor rods on the lower surface of the embedded steel plate are welded to the steel reinforcement cage.

[0011] This utility model provides a telescopic double-shed heavy-duty steel rail mobile work shed for construction sites. It has the following beneficial effects: 1. The telescopic double-shed heavy-duty rail mobile work shed at the construction site adopts a reinforced base structure that includes a concrete strip foundation, embedded steel plates, and heavy-duty rails, and is properly anchored with elastic rail sleepers. This design creates a mobile platform with high load-bearing capacity and high stability. It fundamentally overcomes the defects of traditional light rails that are easy to deform and deviate.

Both the large shed body 1 and the small shed body 2 include multiple columns 5, and the top of each column 5 is welded with a tubular truss arch beam 6. The moving module 4 is fixedly installed at the bottom of the column 5 on one side of the large shed body 1 and the small shed body 2. The moving module 4 includes a first traveling frame 16, and the top of the inner surface of the first traveling frame 16 is fixedly installed with an active traveling wheel 17 and an electric push rod 29. The bottom of the electric push rod 29 is... A locking pin 30 is fixedly installed. A motor 20 is fixedly installed on the upper surface of the first traveling frame 16. A second traveling frame 18 is fixedly installed at the bottom of the remaining columns 5 of the large shed body 1 and the small shed body 2. A driven traveling wheel 19 is fixedly installed on the top of the inner surface of the second traveling frame 18. The base structure 3 includes a concrete strip foundation 10. A pre-embedded steel plate 12 is provided on the upper surface of the concrete strip foundation 10. Multiple sleeper spring strips 13 and multiple locking seats 15 are fixedly installed on the upper surface of the pre-embedded steel plate 12. The pre-embedded steel plate 12 is anchored to the steel rail 14 through the multiple sleeper spring strips 13. The driving traveling wheel 17 and the driven traveling wheel 19 are both adapted to the steel rail 14.

[0017] Specifically, multiple purlins 7 are welded to the top of the tubular truss arch beam 6, and a roof plate 8 is fixedly installed on the top of the purlins 7. Side panels 9 are fixedly installed on the outer surface of the columns 5. The side panels 9 are symmetrically arranged on both sides of the roof plate 8. The tubular truss arch beam 6 serves as the main load-bearing frame, transferring the load to the columns 5. The purlins 7 are used for lateral support and fixing of the roof plate 8. The roof plate 8 forms a rainproof and sunproof closed top surface, the columns 5 provide vertical support, and the side panels 9 constitute a lateral enclosure structure, realizing the ventilation and protection functions of being closed at the top and open at the bottom.

[0018] Specifically, the concrete strip foundation 10 has a steel reinforcement cage 11 inside, and the anchor rods on the lower surface of the embedded steel plate 12 are welded to the steel reinforcement cage 11. The concrete strip foundation 10 provides a uniform and stable bearing base for the track system, and the steel reinforcement cage 11 enhances the tensile strength and integrity of the concrete. The embedded steel plate 12 serves as the mounting base for the upper rail 14 and the locking seat 15, and is welded to ensure a reliable connection with the foundation.

[0019] Specifically, a rotating shaft 21 is fixedly connected to the output end of the motor 20 at the bottom. The bottom end of the rotating shaft 21 extends into the interior of the first traveling frame 16. A first bevel gear 22 is fixedly connected to the bottom end of the rotating shaft 21. A rotating rod 23 is rotatably connected to the inner wall of the first traveling frame 16. A second bevel gear 25 is fixedly connected to the end of the rotating rod 23. The first bevel gear 22 and the second bevel gear 25 mesh. The motor 20 provides power, the rotating shaft 21 transmits torque, and the first bevel gear 22 and the second bevel gear 25 form a reversing transmission pair, converting vertical rotation into horizontal rotation. The rotating rod 23 is used to transmit horizontal power.

[0020] Specifically, a first sprocket 24 is fixedly connected to the outer surface of the rotating rod 23, and a connecting rod 26 is fixedly connected to the center of the driving wheel 17. The outer surface of the connecting rod 26 is rotatably connected to the wheel seat of the driving wheel 17. A second sprocket 27 is fixedly connected to the outer surface of the connecting rod 26. A chain 28 meshes with the outer surfaces of the first sprocket 24 and the second sprocket 27. The first sprocket 24, the second sprocket 27 and the chain 28 form a chain drive mechanism, which transmits the power of the rotating rod 23 to the connecting rod 26. The connecting rod 26 then transmits the rotational motion to the driving wheel 17, driving it to roll along the rail 14.

[0021] Specifically, the outer surface of the locking pin 30 matches the interior of the locking seat 15. The locking pin 30 can be inserted into or disengaged from the locking seat 15 under the drive of the electric push rod 29, so as to achieve mechanical rigid locking after the shed is moved to the target position, prevent accidental movement, and ensure operational safety.

[0022] The working principle of the above embodiments: When the shed needs to be moved, the motor 20 installed on the first traveling frame 16 is started. The motor 20 drives the rotating shaft 21 and the first bevel gear 22 at its bottom to rotate. The first bevel gear 22 drives the second bevel gear 25 meshing with it to rotate, thereby driving the rotating rod 23 to rotate. The first sprocket 24 on the rotating rod 23 transmits power to the second sprocket 27 through the chain 28. The second sprocket 27 drives the connecting rod 26 and the driving wheel 17 fixed thereon to rotate synchronously. The driving wheel 17 rolls on the heavy-duty steel rail 14 anchored to the pre-embedded steel plate 12, thereby driving the side column 5 of the large shed 1 or small shed 2 fixed thereto to move through the first traveling frame 16. The bottom of each of the remaining columns 5 is equipped with a second traveling frame 18 with driven traveling wheels 19. The driven traveling wheels 19 also roll on the steel rail 14, so that the entire shed structure can move smoothly along the steel rail 14, realizing the nested expansion and contraction of the small shed 2 inside the large shed 1. When the shed moves to the target position, the control system issues a command to start the electric push rod 29. The push rod of the electric push rod 29 extends downward and pushes the locking pin 30 fixed at its bottom end to insert downward into the locking seat 15 pre-fixed on the pre-embedded steel plate 12. Through the interlocking of the locking pin 30 and the locking seat 15, the precise position of the entire working shed is locked to prevent it from moving accidentally during operation and to ensure construction safety.

[0023] In addition, the various components of the work shed have clear dimensional specifications: the length of the large shed 1 is 23 meters and the height is 6.2 meters, the length of the small shed 2 is 22 meters and the height is 5.2 meters. The two are nested together with a 1-meter height difference and a 1-meter width difference to form a safe nesting space. The columns 5, which serve as the main load-bearing frame, are made of round tubes with an outer diameter of 165 mm. The main three-sided beams of the truss arch beam 6 are made of round tubes with an outer diameter of 48 mm. The purlins 7 are made of square tubes with a cross-sectional dimension of 40 mm × 80 mm. The roof 8 is usually covered with color steel single panels. The side panels 9 are installed at the top 2.5 meters of the side walls of the shed. The lower part of the side walls of the shed remains open. Neither of the two sheds has a gable wall, forming a through work passage.
