Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a construction platform for tunnel engineering. Background Technology

[0002] A tunnel construction platform is a temporary support structure used in tunnel construction. It primarily provides a safe and stable working platform, facilitating excavation, support, and lining operations. Platforms are typically made of steel or aluminum alloy. They are easy to install, have high load-bearing capacity, and high stability, effectively improving construction efficiency and ensuring worker safety. Construction platforms are essential auxiliary equipment in modern tunnel construction.

[0003] As shown in the reference case "A Tunnel Construction Platform Structure" announcement number "CN222436372U", the designed protective component can cover the gap between the measuring frame and the tunnel, preventing impurities on the upper side frame from falling onto the lower side frame. At the same time, the protective component has a simple structure, is easy to process and manufacture, and has strong overall practicality. In addition, the pull-out protective component can also provide buffer protection to prevent the problem of pinching the fingers of workers caused by excessive pulling speed.

[0004] While the aforementioned application can enhance the protection of workers on the platform by setting up protective components, the poor lighting in tunnels necessitates the use of lighting equipment at the construction site. However, large-scale lighting equipment cannot accurately illuminate the construction area, and workers may also block the light while working, which can easily cause trouble for the construction operation. Utility Model Content

[0005] Therefore, it is necessary to provide a construction platform for tunnel engineering to address the problem of not being able to accurately provide lighting to the construction area.

[0006] A construction platform for tunnel engineering includes: a platform body, and a protective railing is provided around the top of the platform body, wherein the protective railing is a switchable protective railing;

[0007] The lighting mechanism includes two spotlights on both sides of the guardrail. A turntable and a slider are provided below the spotlights. The turntable is rotatably connected to the top of the slider, and the slider is slidably connected to the surface of the guardrail.

[0008] In one embodiment, an extrusion block and a friction pad are provided between the slider and the guardrail, and the friction pad is fixedly connected to the extrusion block.

[0009] In one embodiment, the inner wall of the slider is provided with a first threaded rod, one end of which is rotatably connected to the extrusion block, and the other end of which passes through the slider and is provided with a rotating handle.

[0010] In one embodiment, a plug rod is slidably connected to the side of the slider away from the first threaded rod, and a plurality of insertion holes that cooperate with the plug rod are opened on the lower surface of the turntable. A spring is provided between the bottom end of the plug rod and the slider.

[0011] In one embodiment, two positioning rods are fixedly connected to the surface of the turntable, and the lighting spotlight is rotatably connected between the two positioning rods.

[0012] In one embodiment, the surface of the turntable is provided with a groove, and a hinge block is provided inside the groove that is slidably connected to the inner wall of the turntable. An adjustment rod is hinged between the lower surface of the lighting spotlight and the hinge block.

[0013] In one embodiment, a second threaded rod is provided inside the chute. One end of the second threaded rod is rotatably connected to the inner wall of the turntable, and the other end is fixedly connected to a second bevel gear. A knob is rotatably connected to the inner wall of the upper surface of the turntable. The knob passes through the turntable and is fixedly connected to a first bevel gear. The first bevel gear and the second bevel gear mesh with each other.

[0014] In one embodiment, protective plates are fixedly connected to both sides of the main body of the platform, the protective plates are arranged in a stepped manner, and multiple sets of casters are provided at the bottom of the main body of the platform.

[0015] Beneficial effects

[0016] 1. By installing a guardrail at the top of the platform, the user can be protected. At the same time, by installing spotlights on the surface of the guardrail, a new light source is provided for the construction workers. When the workers are working in the area, the spotlights can accurately illuminate the construction area, providing a good construction environment and reducing the difficulty of the workers' work.

[0017] 2. By setting up a slider, a turntable, and two positioning rods, the lighting spotlights can slide along the surface of the guardrail with the slider. The turntable can also be rotated on the surface of the slider, and the angle can be adjusted between the two positioning rods. This effectively eliminates the lighting blind spots or overlap caused by fixed installation, thereby improving construction accuracy and work efficiency. At the same time, the directional lighting layout significantly reduces shadow interference and blind spots, reducing equipment operation errors, personnel bumps, or safety hazards caused by insufficient local lighting, and meeting the safety specifications requirements for high-intensity construction environments.

[0030] The following is combined Figures 1-4 This invention describes a construction platform for tunnel engineering.

[0031] In one embodiment, a construction platform for tunnel engineering includes: a platform body 100, and a guardrail 110 is provided around the top of the platform body 100. The guardrail 110 is a switchable guardrail 110.

[0032] The lighting mechanism 300 includes two spotlights 330 disposed on both sides of the guardrail 110. A turntable 320 and a slider 310 are disposed below the spotlights 330. The turntable 320 is rotatably connected to the top of the slider 310, and the slider 310 is slidably connected to the surface of the guardrail 110.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, a pressing block 313 and a friction pad 312 are provided between the slider 310 and the guardrail 110. The friction pad 312 is fixedly connected to the pressing block 313. A first threaded rod 311 is provided on the inner wall of the slider 310. One end of the first threaded rod 311 is rotatably connected to the pressing block 313, and the other end of the first threaded rod 311 passes through the slider 310 and is provided with a rotating handle. An insert rod 315 is slidably connected to the side of the slider 310 away from the first threaded rod 311. The lower surface of the turntable 320 has multiple insertion holes 321 that mate with the insert rod 315. A spring 314 is provided between the bottom end of the insert rod 315 and the slider 310. Two positioning rods 33 are fixedly connected to the surface of the turntable 320. 1. The lighting spotlight 330 is rotatably connected between two positioning rods 331. The surface of the turntable 320 is provided with a sliding groove. The inside of the sliding groove is provided with a hinge block 333 that is slidably connected to the inner wall of the turntable 320. An adjusting rod 334 is hinged between the lower surface of the lighting spotlight 330 and the hinge block 333. The inside of the sliding groove is provided with a second threaded rod 332. One end of the second threaded rod 332 is rotatably connected to the inner wall of the turntable 320 and the other end is fixedly connected to a second bevel gear 336. A knob 337 is rotatably connected to the inner wall of the upper surface of the turntable 320. The knob 337 passes through the turntable 320 and is fixedly connected to a first bevel gear 335. The first bevel gear 335 and the second bevel gear 336 mesh with each other.

[0034] In this embodiment, the device can be configured according to the size of the tunnel. When constructing a large tunnel, workers need to be transported to the top of the platform body 100 by machine for work. When constructing a small tunnel, ladders can be installed on both sides of the platform body to allow workers to move to the top of the guardrail 110 on their own. When continuous construction is required inside the tunnel for a long time, portable batteries can be provided for the lighting to continue operation. The friction pad 312 is made of rubber. The end of the insertion rod 315 is provided with a disc-shaped limiting block and a ball-shaped block for easy pulling down. The ball-shaped block and the disc-shaped limiting block are fixedly connected. The surface of the slider 310 is provided with a protrusion. The slider is slidably connected to the protrusion. The spring... 314 is positioned between the protruding block and the disc-shaped limiting block; the threaded portion of the first threaded rod 311 is always inside the slider 310, thus effectively preventing small stones and other debris from entering the thread and affecting the first threaded rod 311. At the same time, a baffle is provided above the second threaded rod 332. The baffle passes through the hinge block 333 and is fixedly connected to the top of the slide groove. However, because the width of the baffle is smaller than the bottom end of the hinge block 333, there is still a gap between the second threaded rod 332 and the outside. In order to completely prevent the influence of external debris on the second threaded rod 332, a retractable spring 314 needs to be sleeved on the surface of the second threaded rod 332 to protect the second threaded rod 332 from contacting the outside.

[0035] The lighting mechanism 300 of this device is installed on the surface of the guardrails 110 on both sides. Due to its sliding and angle-adjustable nature, its position can be adjusted to effectively avoid interference with the workers during construction and will not affect the overall effect of the construction platform.

[0036] like Figure 1 As shown, protective plates 120 are fixedly connected to both sides of the main body 100 of the platform. The protective plates 120 are arranged in a stepped manner, and multiple sets of casters 200 are provided at the bottom of the main body 100 of the platform.

[0037] In this embodiment, the stepped protective plates 120 on both sides of the platform body mainly serve to prevent objects from falling, protect personnel safety, and provide a certain protective barrier to prevent external personnel or equipment from contacting the dangerous area. The stepped design helps to better adapt to different heights and work requirements, enhances the protective effect, and improves the stability and safety of the overall structure, ensuring that accidental injuries or equipment damage are avoided during operation. Each set of casters 200 is equipped with a locking mechanism, which can be used to fix the platform after it is moved to the construction area.

[0038] Working principle: The platform body is moved to the construction area inside the tunnel by the rotating wheel 200, and then the machine transports the workers to the top of the platform. Then the guardrail 110 is closed and locked to start the work.

[0039] When the lighting in the construction area is insufficient, the spotlights 330 can be turned on and adjusted to be aimed at the construction area. During the adjustment process, first, the first threaded rod 311 is rotated by turning the handle. The first threaded rod 311 drives the pressing block 313 to move the friction pad 312 outward. Then, the entire lighting mechanism 300 is moved to a suitable position on the guardrail 110 by the slider 310. Then, the handle is rotated in the opposite direction, so that the first threaded rod 311 drives the pressing block 313 to press the friction pad 312. By increasing the pressure of the friction pad 312 on the guardrail 110, the friction between the friction pad 312 and the guardrail 110 is increased. The slider 310 is fixed by the friction. Then, the insertion rod 315 is pulled downward, so that its top end is inserted from the insertion rod. The light fixture 330 is disengaged from the hole 321. Then, the turntable 320 is rotated to drive the lighting spotlight 330 to rotate horizontally. After the position of the turntable 320 is adjusted, the insertion rod 315 is released. Under the action of the spring 314, the insertion rod 315 is inserted into the insertion hole 321 to fix the turntable 320. Then, the first bevel gear 335 is rotated by rotating the knob 337. The rotation of the first bevel gear 335 drives the second bevel gear 336 to rotate, which in turn drives the second threaded rod 332 to rotate, causing the hinge block 333 to move along the sliding groove opened in the turntable 320. While the hinge block 333 is moving, it will push the lighting spotlight 330 to rotate along the two positioning rods 331 through the adjusting rod 334. After adjusting the lighting spotlight 330 to a suitable angle, stop rotating the knob 337.

[0040] It should be noted that the lighting spotlight 330, the first threaded rod 311, the second threaded rod 332, the first bevel gear 335, and the second bevel gear 336 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the lighting spotlight 330 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
