Description

Technical Field

[0001] This utility model relates to the technical field of building safety construction, and more specifically, to a foldable temporary passageway for building construction. Background Technology

[0002] With societal development, high-rise buildings have become the mainstream of new residential construction, with floors increasingly taller, mostly exceeding 20 stories. Tower cranes are large lifting equipment commonly used in construction. Due to the distance between the tower crane and the building under construction, a temporary passage needs to be built between the tower crane and the building to save the crane operator's climbing time and avoid potential safety hazards during climbing. This temporary passage, which is then used to climb the crane ladder to reach the operator's cab, needs to be constantly rebuilt as the building height increases. This process is not only time-consuming and labor-intensive but also poses significant safety risks. A search revealed that publication number CN213923828U discloses a liftable and foldable temporary access passage for tower cranes. Its features include a fixed part and a folding part, which are rotatably connected by pins. A fixed frame is provided on both sides of the front end of the fixed part; the fixed frame is installed on a standard section of the tower crane, and a roller is provided on the upper end of the fixed frame; the roller is driven by a winch, and a traction rope is installed on the roller; the other end of the traction rope is fixed to the bottom of the folding part; the winch is connected to the power distribution cabinet of the tower crane cab; guardrails are provided on both sides of the folding part, and the guardrails include horizontal bars one, two, and three, and vertical bars one and two. Horizontal bars one and two are rotatably connected by pins, and the two ends of horizontal bar three are respectively fixed to the upper ends of vertical bars one and two. This utility model has the positive effects of being liftable and foldable, saving time and effort, and reducing safety hazards. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: However, most temporary passageways lack sunshade facilities, so when the temperature is high, employees are easily exposed to direct sunlight when passing through them, which can easily lead to heatstroke.

[0003] Therefore, a foldable temporary access road for building construction is proposed to address the above issues. Summary of the Invention

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] As attached Figures 1 to 5The foldable temporary construction passage shown includes a fixed frame 1, with a guide rail 2 fixedly connected to the upper surface of the fixed frame 1. A movable mechanism 3 is provided on the upper surface of the guide rail 2. The movable mechanism 3 includes a connecting rod 31, which is slidably connected to the guide rail 2. A slider 32 is slidably connected to the front surface of the connecting rod 31. The slider 32 is hinged to one end of a support 33. The guide rail 2 is hinged to the other end of the support 33. A connecting rod 34 is slidably connected to the upper surface of the guide rail 2 in a linear array. A slider 35 is slidably connected to the front surface of the connecting rod 34. The slider 35 is hinged to one end of a support 36. The sliding connection between the connecting rod 31 and the guide rail 2 allows the connecting rod 31 to move flexibly along the guide rail 2, providing basic space for the unfolding and folding of the entire movable mechanism. The front surface of connecting rod 31 is slidably connected to slider 32. Slider 32 is connected to one end of bracket 33 by hinge. At the same time, guide rail 2 is also connected to the other end of bracket 33 by hinge. This hinge structure gives bracket 33 the ability to rotate flexibly within a certain range. The upper surface of guide rail 2 is slidably connected to connecting rod 34 in a linear array. This distribution ensures that the moving mechanism 3 is evenly stressed and moves in a coordinated manner in various parts.The front surface of connecting rod 2 34 is also slidably connected to slider 2 35. Slider 2 35 is hinged to one end of bracket 2 36, and slider 1 32 is also hinged to the other end of bracket 2 36. Through these hinged connections, bracket 1 33 and bracket 2 36 cooperate with each other, enabling the entire movable mechanism 3 to maintain a stable structural shape during unfolding and folding, playing an important role in angle adjustment during the folding and unfolding of the channel. Slider 1 32 is hinged to the other end of bracket 2 36. The front surfaces of connecting rod 1 31 and connecting rod 2 34 are provided with multiple sets of sliding grooves 37. Multiple sets of sliding grooves 37 are slidably connected to slider 1 32 and slider 2 35. The sliding grooves 37 not only provide a precise track for the movement of slider 1 32 and slider 2 35, but also, through this cooperation, further enhance the stability and accuracy of the movable mechanism 3 during movement, ensuring the stability of each component. The relative positions between them can be accurately adjusted according to the design requirements. The front surfaces of connecting rod 1 31 and connecting rod 2 34 are fixedly connected to fixing blocks 38 in a linear array. The upper surface of fixing block 38 has a pin 39 through it and is slidably connected to the pin 39. The pin 39 is fixedly connected to one end of spring 1 310. Spring 1 310 provides elastic restoring force for the pin 39, so that the pin 39 can automatically reset after being inserted or pulled out by external force, which is convenient for fixing or unlocking the movable mechanism 3 in different states. The other end of fixing block 38 is fixedly connected to spring 1 310. The upper surface of guide rail 2 has slots 311 in a linear array. The slots 311 are slidably connected to the pin 39. In addition, a sealing structure can be designed for the connection between the pin 39 and the slot 311 to prevent dust, debris and other objects from entering during construction and affecting the normal insertion, removal and locking functions of the pin 39. At the bottom of the fixed frame 1, casters with brakes can be installed, allowing the entire temporary passage to be easily moved to the desired position when not fixed, thus improving its flexibility of use.

[0022] Specifically: When a temporary passage needs to be deployed, the connecting rod 31 of the movable mechanism 3 is slidably connected to the guide rail 2, pulling the connecting rod 31 to slide along the guide rail 2. At this time, the slider 32, which is slidably connected to the front surface of the connecting rod 31, will slide in the groove 37 on the connecting rod 31. At the same time, because the slider 32 is hinged to one end of the bracket 33, and the other end of the bracket 33 is hinged to the guide rail 2, as the connecting rod 31 slides, the bracket 33 will rotate about the hinge point with the guide rail 2 as the axis, gradually unfolding. While the connecting rod 31 slides, the connecting rods 34, which are linearly arrayed and slidably connected to the upper surface of the guide rail 2, will also slide synchronously. The slider 35, which is slidably connected to the front surface of the connecting rod 34, slides in its groove 37. The slider 35 is hinged to one end of the bracket 36, and the slider 32 is hinged to the other end of the bracket 36. This allows the bracket 36 to unfold as the connecting rod 31 and the connecting rod 34 slide. Through the hinge and sliding cooperation between the components, the entire channel structure can be unfolded. When it is unfolded to a suitable position and needs to be fixed, the pins 39 on the fixing blocks 38, which are linearly arrayed on the front surface of the connecting rod 31 and the connecting rod 34, slide and engage in the slots 311, which are linearly arrayed on the upper surface of the guide rail 2, under the elastic force of the spring 310. This fixes the connecting rod 31, the connecting rod 34, and the guide rail 2, maintaining the stability of the channel after it is unfolded. Example

[0023] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, a support mechanism 4 is provided on the upper surface of connecting rod 1 31 and connecting rod 2 34. The support mechanism 4 includes an arc-shaped rod 41, and multiple sets of arc-shaped rods 41 are provided. The multiple sets of arc-shaped rods 41 are rotatably connected to connecting rod 1 31 and connecting rod 2 34. The arc-shaped rods 41 can support the sunshade cloth, so that employees are not affected by direct sunlight when passing through.

[0024] In a preferred embodiment, the outer arc surface of the arc-shaped rod 41 is penetrated by the fixed rod 42 and is slidably connected to the fixed rod 42, and the outer arc surface of the fixed rod 42 is provided with a spring 43.

[0025] In a preferred embodiment, the right surface of the fixed frame 1 is provided with mounting holes 5 in a linear array. The mounting holes 5 facilitate the fixing of the fixed frame 1 to other locations where temporary passageways need to be built.

[0026] The working process of this utility model is as follows: First, when it is necessary to unfold the temporary passage, the connecting rod 31 of the movable mechanism 3 is slidably connected to the guide rail 2, and the connecting rod 31 is pulled to slide along the guide rail 2. At this time, the slider 32, which is slidably connected to the front surface of the connecting rod 31, will slide in the groove 37 on the connecting rod 31. At the same time, because the slider 32 is hinged to one end of the bracket 33, and the other end of the bracket 33 is hinged to the guide rail 2, the bracket 33 will rotate around the hinge point with the guide rail 2 as the connecting rod 31 slides, and gradually unfold. At the same time as the connecting rod 31 slides, the connecting rod 34, which is linearly arrayed and slidably connected to the upper surface of the guide rail 2, will also slide synchronously. The multiple sets of arc rods 41 of the support mechanism 4 are rotatably connected to the connecting rod 31 and the connecting rod 34. When the movable mechanism is adjusted to a suitable position, the arc rod 41 can rotate around the connection point with the connecting rod to adjust the height of the sunshade cloth laid above the passage. At the same time, the outer arc surface of the fixing rod 42 is provided with a spring 43. Spring 43 can buffer and provide elastic support for the arc-shaped rod 41. For example, when the passage is subjected to a certain pressure, spring 43 can be compressed to relieve the impact of the pressure on the passage structure and ensure the stability of the passage. The above is the working principle of this foldable temporary construction passage.
